The EPICS Process Variable Gateway is both a Channel Access Server and Channel Access Client that provides a means for many clients, typically on different subnets, to access a process variable while making only one connection to the server that owns the process variable. It also provides additional access security beyond that implemented on the server. It thus protects critical servers while providing suitably restricted access to needed process variables. The original version of the Gateway worked with EPICS Base 3.13 but required a special version, since the changes necessary for its operation were never incorporated into EPICS Base. Version 2 works with any standard EPICS Base 3.14.6 or later and has many improvements in both performance and features over the older version. The Gateway is now used at many institutions and has become a stable, high-performance application. It is capable of handling tens of thousands of process variables with hundreds of thousands of events per second. It has run for over three months in a production environment without having to be restarted. It has many internal process variables that can be used to monitor its state using standard EPICS client tools, such as MEDM and StripTool. Other internal process variables can be used to stop the Gateway, make several kinds of reports, or change the access security without stopping the Gateway. It can even be started on remote workstations from MEDM by using a Secure Shell script. This paper will describe the new Gateway and how it is used. The Gateway is both a server (like an EPICS Input/Output Controller (IOC)) and a client (like the EPICS Motif Editor and Display Manager (MEDM), StripTool, and others). Clients connect to the server side, and the client side connects to IOCs and other servers, possibly other Gateways. See Fig. 1. There are perhaps three principal reasons for using the Gateway: (1) it allows many clients to access a process variable while making only one connection to

This document describes the core software that resides in an Input/Output Controller (IOC), one of the major components of EPICS. The basic components are: (OPI) Operator Interface; this is a UNIX based workstation which can run various EPICS tools; (IOC) Input/Output Controller; this is a VME/VXI based chassis containing a Motorola 68xxx processor, various I/O modules, and VME modules that provide access to other I/O buses such as GPIB, (LAN), Local Area Network; and this is the communication network which allows the IOCs and OPIs to communicate. Epics provides a software component, Channel Access, which provides network transparent communication between a Channel Access client and an arbitrary number of Channel Access servers

The Experimental Physics and Industrial Control System (EPICS) provides control and data acquisition for the experimental physics community. Because the capabilities required by the experimental physics community for control were not available through industry, we began the design and implementation of EPICS. It is a distributed process control system built on a software communication bus. The functional subsystems, which provide data acquisition, supervisory control, closed loop control, archiving, and alarm management, greatly reduce the need for programming. Sequential control is provided through a sequential control language, allowing the implementer to express state diagrams easily. Data analysis of the archived data is provided through an interactive tool. The timing system provides distributed synchronization for control and time stamped data for data correlation across nodes in the network. The system is scalable from a single test station with a low channel count to a large distributed network with thousands of channels. The functions provided to the physics applications have proven helpful to the experiments while greatly reducing the time to deliver controls. (author)

In He RFQ device, the high-power Radio-Frequency (RF) is very important because it is responsible for the stable delivery and efficient acceleration of the beam. Since that, the control system of high-power Radio-Frequency must be developed and this system is called LLRF control system. The LLRF control system required exquisite amplitude value that has ±1 % error range. We need a precise remote control system for this reason. This paper represents the configuration of LLRF control system in terms of software layers based on EPICS. Also, this paper explains the application of LLRF control system to test environment (hardware) and represents test result and suggests future work. The LLRF control system at the He RFQ is very important. The configuration of LLRF control system is completed on the software side and hardware modules: vxworks operating system installation, EPICS BASE compilation, module source code compiled, object file loading and execution on vxworks, EPICS IOC operation check, etc. The application of LLRF control system to module is implemented well: ADC module, DAC module, EPICS IOC test.

The performance evaluation and analysis of intersystem dependency of the various subsystems of the Superconducting Cyclotron (SCC) demand a well configured data logging, archiving and historic analysis facility for large number of control parameters along with on-line failure analysis facility of every system. Experimental Physics and Industrial Control System (EPICS) is used as development architecture of the control system of these systems with MySQL as database for large amount of relational data management. This combination requires integration between EPICS and MySQL server. For this purpose, MySQL Archiver as an EPICS Extension is developed for data logging and archiving of control parameters into MySQL database. This extension also provides a web based tool for online monitoring of control parameters and historic analysis of archived data. This paper describes the software architecture, implementation, as well as method of configuration for any other EPICS based control system as a utility. This facility is also elaborated with examples, web page views and experiences of deploying it in SCC. (author)

EPICS: operating system independent device/driver support

International Nuclear Information System (INIS)

Kraimer, M.R.

2003-01-01

Originally EPICS input/output controllers (IOCs) were only supported on VME-based systems running the vxWorks operating system. Now IOCs are supported on many systems: vxWorks, RTEMS, Solaris, HPUX, Linux, WIN32, and Darwin. A challenge is to provide operating-system-independent device and driver support. This paper presents some techniques for providing such support. EPICS (Experimental Physics and Industrial Control System) is a set of software tools, libraries, and applications developed collaboratively and used worldwide to create distributed, real-time control systems for scientific instruments such as particle accelerators, telescopes, and other large scientific experiments. An important component of all EPICS-based control systems is a collection of input/output controllers (IOCs). An IOC has three primary components: (1) a real-time database; (2) channel access, which provides network access to the database; and (3) device/driver support for interfacing to equipment. This paper describes some projects related to providing device/driver support on non-vxWorks systems. In order to support IOCs on platforms other than vxWorks, operating-system-independent (OSI) application program interfaces (APIs) were defined for threads, semaphores, timers, etc. Providing support for a new platform consists of providing an operating-system-dependent implementation of the OSI APIs.

EPICS is a set of software tools and applications developed collaboratively and used to create distributed soft real-time control systems for scientific instruments such as particle accelerators and telescopes. Such distributed control systems typically comprise tens or even hundreds of computers, networked together to allow communication between them and to provide control and feedback of the various parts of the device from a central control room, or even remotely over the internet. EPICS uses Client/Server and Publish/Subscribe techniques to communicate between the various computers. A Channel Access Gateway allows engineers and physicists elsewhere in the building to examine the current state of the IOCs, but prevents them from making unauthorized adjustments to the running system. In many cases the engineers can make a secure internet connection from home to diagnose and fix faults without having to travel to the site. EPICS is used by many facilities worldwide, including the Advanced Photon Source at Argonne National Laboratory, Fermilab, Keck Observatory, Laboratori Nazionali di Legnaro, Brazilian Synchrotron Light Source, Los Alamos National Laboratory, Australian Synchrotron, and Stanford Linear Accellerator Center.

Experimental Physics and Industrial Control System (EPICS) SCADA software package is popular worldwide for deploying accelerator control systems. EPICS base allows building server applications that interact with EPICS compliant lower level hardware, embedded systems, commercial PLCs on one side and facilitates seamless connectivity with EPICS clients on the other side. Large number of such lower level (EPICS complaint) networked systems work in collaborative environment for physics experiment. RCnD has developed a PLC platform, Trombay Programmable Logic Controller TPLC-32 for deploying C and I systems of NPP and allied utilities. This platform is now also being used for deploying accelerator C and I systems. Hence the activity of developing TPLC-32 interface with EPICS was taken up in RCnD. This paper introduces the architecture of the EPICS Input Output Controller (IOC) and describes the implementation of the EPICS SoftIOC for TPLC-32. It also describes Operator Interface developed using MEDM EPICS client for LEHIPA vacuum control system built using TPLC-32. (author)

The Korea Superconducting Tokamak Advanced Research (KSTAR) control system will be developed with several subsystems, which consist of the central control system (e.g. plasma control, machine control, diagnostic control, time synchronization, and interlock systems) and local control systems for various subsystems. We are planning to connect the entire system with several networks, viz. a reflective-memory-based real-time network, an optical timing network, a gigabit Ethernet network for generic machine control, and a storage network. Then it will evolve into a network-based, distributed real-time control system. Thus, we have to consider the standard communication protocols among the subsystems and how to handle the various kinds of hardware in a homogeneous way. To satisfy these requirements, EPICS has been chosen for the KSTAR control. The EPICS framework provides network-based real-time distributed control, operating system independent programming tools, operator interface tools, archiving tools, and interface tools with other commercial and non-commercial software. The most important advantage of the use of the EPICS framework is in providing homogeneity of the system for the control system developer. The developer does not have to be concerned about the specifics of the local system, but can concentrate on the implementation of the control logic with EPICS tools. We will present the details of the integration issues and also will give a brief summary of the entire KSTAR control system from an integration point of view

Modern control systems applications are often built on top of a real time operating system. At LEHIPA beamlines, open source control systems offer a modem solution for cost effectiveness and technical competence. The 'Experimental Physics and Industrial Control System' (EPICS) and the 'Real-Time Operating System for Multiprocessor Systems' (RTEMS) were chosen to develop the core control system. Presently, the EPICS/RTEMS/MVME5500 control system is implemented for RF Protection Interlock system and BPM. This paper shares an experience of building RTEMS for MVME5500, configuring and run EPICS for RTEMS-MVME5500 architecture. It further shows EPICS bench marking results using EPICS catime and hamesstest utilities for this architecture. (author)

Highlights: • Underlying functionalities are encapsulated into plug-and-play modules. • The slow controller is EPICS compatible. • The slow controller can work as PSH. - Abstract: J-TEXT tokamak has recently implemented J-TEXT COntrol, Data Access and Communication (CODAC) system on the principle of ITER CODAC. The control network in J-TEXT CODAC system is based on Experimental Physics and Industrial Control System (EPICS). However, former slow plant system controllers in J-TEXT did not support EPICS. Therefore, J-TEXT has designed an EPICS compatible slow controller. And moreover, the slow controller also acts the role of Plant System Host (PSH), which helps non-EPICS controllers to keep working in J-TEXT CODAC system. The basic functionalities dealing with user defined tasks have been modularized into driver or plug-in modules, which are plug-and-play and configured with XML files according to specific control task. In this case, developers are able to implement various kinds of control tasks with these reusable modules, regardless of how the lower-lever functions are implemented, and mainly focusing on control algorithm. And it is possible to develop custom-built modules by themselves. This paper presents design of the slow controller. Some applications of the slow controller have been deployed in J-TEXT, and will be introduced in this paper.

The Qt-based GUI system developed at the Australian Synchrotron for use on EPICS control systems has recently been enhanced to including support for imaging, plotting, user login, logging and configuration recipes. Plans are also being made to broaden its appeal within the wider EPICS community by expanding the range of development options and adding support for EPICS V4. Current features include graphical and non-graphical application development as well as simple 'code-free' GUI design. Additional features will allow developers to let the GUI system handle its own data using Qt-based EPICS-aware classes or, as an alternative, use other control systems data such as PSI's CAFE.

EPICS is used worldwide mostly for controlling accelerators and large experimental physics facilities. Although EPICS is well fit for the design and development of automation systems, which are typically VME or PLC-based systems, and for soft real-time systems, it may present several drawbacks when used to develop hard real-time systems/applications especially when general purpose operating systems as plain Linux are chosen. This is in particular true in fusion research devices typically employing several hard real-time systems, such as the magnetic control systems, that may require strict determinism, and high performance in terms of jitter and latency. Serious deterioration of important plasma parameters may happen otherwise, possibly leading to an abrupt termination of the plasma discharge. The MARTe framework has been recently developed to fulfill the demanding requirements for such real-time systems that are alike to run on general purpose operating systems, possibly integrated with the low-latency real-time preemption patches. MARTe has been adopted to develop a number of real-time systems in different Tokamaks. In this paper, we first summarize differences and similarities between EPICS IOC and MARTe. Then we report on a set of performance measurements executed on an x86 64 bit multicore machine running Linux with an IO control algorithm implemented in an EPICS IOC and in MARTe.

The National Spherical Torus Experiment (NSTX) has been in operation at the Princeton Plasma Physics Laboratory (PPPL) since 1999. Since then, NSTX has made use of the Experimental Physics and Industrial Control System (EPICS) and MDSplus software packages, among others for control and data acquisition. To date, the two products have been integrated using special 'bridging' programs that include client-components for the EPICS and MDSplus servers. Recent improvements in the EPICS software have made it easier to develop a direct interface with MDSplus. This paper will describe the new EPICS extensions developed at PPPL that provide: (1) a direct data interface between EPICS process variables and MDSplus nodes; and (2) an interface between EPICS events and MDSplus events. These extensions have been developed for use with EPICS on Solaris and are currently being modified for use on real-time operating systems. Separately, an XML-RPC client was written to access EPICS 'trended' data, sampled usually once per minute during a 24 h period. The client extracts and writes a day's worth of trended data to a 'daily' MDSplus tree

The US Department of Energy's (DOE's) Pollution Prevention Information Clearinghouse (EPIC) is a computer system intended for the exchange of pollution prevention information DOE-wide. EPIC is being developed as a distributed system that will allow access to other databases and applications. The first prototype of EPIC (Prototype I) was put on-line in January 1994. Prototype I contains information on EM-funded pollution prevention projects; relevant laws, regulations, guidance, and policy; facility and DOE contacts; and meetings and conferences. Prototype I also gives users access to the INEL Hazardous Solvent Substitution Data System (HSSDS) and to information contained on the US Environmental Protection Agency's (EPNS) Pollution Prevention Infbrmation Exchange System (PIES) as a test of the distributed system concept. An initial user group of about 35 is testing and providing feedback on Prototype I. Prototype II, with a Graphical User Interface (GUI), is planned for the end of CY94. This paper describes the current state of EPIC in terms of architecture, user interface, and information content. Plans for Prototype II and the final system are then discussed. The EPIC development effort is being coordinated with EPA and US Department of Defense (DoD) efforts to develop or upgrade their pollution prevention information exchange systems

Diamond Light Source has recently received funding for an additional 10 photon beamlines, bringing the total to 32 beamlines and around 40 end-stations. These all use EPICS (Experimental Physics and Industrial Control System) for the control of the underlying instrumentation associated with photon delivery, the experiment and most of the data acquisition hardware. For the scientific users Diamond has developed the Generic Data Acquisition (GDA) application framework to provide a consistent science interface across all beamlines. While each application is customized to the science of its beamline, all applications are built from the framework and predominantly interface to the underlying instrumentation through the EPICS abstraction. We will describe the complete system, illustrate how it can be configured for a specific beamline application, and how other synchrotrons are, and can, adapt these tools for their needs. (authors)

For unattended telescopes in Antarctic, the remote operation, autonomous observation and control are essential. An EPICS-(Experimental Physics and Industrial Control System) and RTS2-(Remote Telescope System, 2nd Version) based autonomous observation and control system with remoted operation is introduced in this paper. EPICS is a set of open source software tools, libraries and applications developed collaboratively and used worldwide to create distributed soft real-time control systems for scientific instruments while RTS2 is an open source environment for control of a fully autonomous observatory. Using the advantage of EPICS and RTS2, respectively, a combined integrated software framework for autonomous observation and control is established that use RTS2 to fulfil the function of astronomical observation and use EPICS to fulfil the device control of telescope. A command and status interface for EPICS and RTS2 is designed to make the EPICS IOC (Input/Output Controller) components integrate to RTS2 directly. For the specification and requirement of control system of telescope in Antarctic, core components named Executor and Auto-focus for autonomous observation is designed and implemented with remote operation user interface based on browser-server mode. The whole system including the telescope is tested in Lijiang Observatory in Yunnan Province for practical observation to complete the autonomous observation and control, including telescope control, camera control, dome control, weather information acquisition with the local and remote operation.

Lessons learned enhancing EPICS CA for LANSCE timed and flavored data

Hill, Jeffrey O.

2009-01-01

A previous paper described an upgrade to EPICS enabling client side tools at LANSCE to receive subscription updates filtered selectively to match a logical configuration of LANSCE beam gates, as configured by the control room. The upgrade required fundamental changes in the EPICS core components. First, the event queue in the EPICS server was upgraded to buffer record (function block) and device specific parameters accessed generically via software interfaces for introspection of 3rd party data. In contrast, event queues in previous versions of EPICS were strictly limited to buffering only value, timestamp, and alarm status tuples. Second, the Channel Access server is being upgraded to filter subscription updates. In this follow on paper some necessary design changes mid-project and the lessons learned during the software development will be described.

The advent of array-based genome-wide DNA methylation methods has enabled quantitative measurement of single CpG methylation status at relatively low cost and sample input. Whereas the use of Infinium Human Methylation BeadChips has shown great utility in clinical studies, no equivalent tool is available for rodent animal samples. We examined the feasibility of using the new Infinium MethylationEPIC BeadChip for studying DNA methylation in mouse. In silico, we identified 19,420 EPIC probes (referred as mEPIC probes), which align with a unique best alignment score to the bisulfite converted reference mouse genome mm10. Further annotation revealed that 85% of mEPIC probes overlapped with mm10.refSeq genes at different genomic features including promoters (TSS1500 and TSS200), 1st exons, 5'UTRs, 3'UTRs, CpG islands, shores, shelves, open seas and FANTOM5 enhancers. Hybridization of mouse samples to Infinium Human MethylationEPIC BeadChips showed successful measurement of mEPIC probes and reproducibility between inter-array biological replicates. Finally, we demonstrated the utility of mEPIC probes for data exploration such as hierarchical clustering. Given the absence of cost and labor convenient genome-wide technologies in the murine system, our findings show that the Infinium MethylationEPIC BeadChip platform is suitable for investigation of the mouse methylome. Furthermore, we provide the "mEPICmanifest" with genomic features, available to users of Infinium Human MethylationEPIC arrays for mouse samples.

Calibration of the DSCOVR EPIC Visible and NIR Channels using MODIS Terra and Aqua Data and EPIC Lunar Observations

The unique position of the Deep Space Climate Observatory (DSCOVR) Earth Polychromatic Imaging Camera (EPIC) at the Lagrange 1 point makes an important addition to the data from currently operating low Earth orbit observing instruments. EPIC instrument does not have an onboard calibration facility. One approach to its calibration is to compare EPIC observations to the measurements from polar-orbiting radiometers. Moderate Resolution Imaging Spectroradiometer (MODIS) is a natural choice for such comparison due to its well-established calibration record and wide use in remote sensing. We use MODIS Aqua and Terra L1B 1km reflectances to infer calibration coefficients for four EPIC visible and NIR channels: 443, 551, 680 and 780 nm. MODIS and EPIC measurements made between June 2015 and 2016 are employed for comparison. We first identify favorable MODIS pixels with scattering angle matching temporarily collocated EPIC observations. Each EPIC pixel is then spatially collocated to a subset of the favorable MODIS pixels within 25 km radius. Standard deviation of the selected MODIS pixels as well as of the adjacent EPIC pixels is used to find the most homogeneous scenes. These scenes are then used to determine calibration coefficients using a linear regression between EPIC counts/sec and reflectances in the close MODIS spectral channels. We present thus inferred EPIC calibration coefficients and discuss sources of uncertainties. The lunar EPIC observations are used to calibrate EPIC O2 absorbing channels (688 and 764 nm), assuming that there is a small difference between moon reflectances separated by approx.10 nm in wavelength provided the calibration factors of the red (680 nm) and near-IR (780 nm) are known from comparison between EPIC and MODIS.

Experience using EPICS on PC platforms

The Experimental Physics and Industrial Control System (EPICS) has been widely adopted in the accelerator community. Although EPICS is available on many platforms, the majority of implementations have used UNIX workstations as clients, and VME- or VXI-based processors for distributed input output controllers. Recently, a significant portion of EPICS has been ported to personal computer (PC) hardware platforms running Microsoft's operating systems, and also Wind River System's real time vxWorks operating system. This development should significantly reduce the cost of deploying EPICS systems, and the prospect of using EPICS together with the many high quality commercial components available for PC platforms is also encouraging. A hybrid system using both PC and traditional platforms is currently being implemented at LANL for LEDA, the low energy demonstration accelerator under construction as part of the Accelerator Production of Tritium (APT) project. To illustrate these developments the authors compare their recent experience deploying a PC-based EPICS system with experience deploying similar systems based on traditional (UNIX-hosted) EPICS hardware and software platforms

Calibration of the DSCOVR EPIC visible and NIR channels using MODIS Terra and Aqua data and EPIC lunar observations

Full Text Available The unique position of the Deep Space Climate Observatory (DSCOVR Earth Polychromatic Imaging Camera (EPIC at the Lagrange 1 point makes an important addition to the data from currently operating low Earth orbit observing instruments. EPIC instrument does not have an onboard calibration facility. One approach to its calibration is to compare EPIC observations to the measurements from polar-orbiting radiometers. Moderate Resolution Imaging Spectroradiometer (MODIS is a natural choice for such comparison due to its well-established calibration record and wide use in remote sensing. We use MODIS Aqua and Terra L1B 1 km reflectances to infer calibration coefficients for four EPIC visible and NIR channels: 443, 551, 680 and 780 nm. MODIS and EPIC measurements made between June 2015 and 2016 are employed for comparison. We first identify favorable MODIS pixels with scattering angle matching temporarily collocated EPIC observations. Each EPIC pixel is then spatially collocated to a subset of the favorable MODIS pixels within 25 km radius. Standard deviation of the selected MODIS pixels as well as of the adjacent EPIC pixels is used to find the most homogeneous scenes. These scenes are then used to determine calibration coefficients using a linear regression between EPIC counts s−1 and reflectances in the close MODIS spectral channels. We present thus inferred EPIC calibration coefficients and discuss sources of uncertainties. The lunar EPIC observations are used to calibrate EPIC O2 absorbing channels (688 and 764 nm, assuming that there is a small difference between moon reflectances separated by  ∼  10 nm in wavelength and provided the calibration factors of the red (680 nm and NIR (780 nm are known from comparison between EPIC and MODIS.

The alarm detecting layer is the component that monitors alarm signals which are transported to the processing part through message queue. The main purpose of the processing part is to transfer the alarm signals connecting an alarm identification and state of the alarm to database system. The operation interface of system level signal links has been developed by EPICS framework. EPICS tools have been used for monitoring device alarm status. The KOMAC alarm system was developed for offering a user-friendly, intuitive user interface. The alarm system is implemented with EPICS IOC for alarm server, eclipse-mars integrated development tool for alarm viewer, and mariadb for alarm log. The new alarm system supports intuitive user interface on alarm information and alarm history. Alarm view has plans to add login function, user permission on alarm acknowledge, user permission of PV import, search and report function.

This paper presents a developed, tested and integrated EPICS IOC (I/O controller) module solution for the ISTTOK tokamak machine operation and control for the vacuum and gas injection systems. The work is organized in two software layers which communicate through a serial RS-232 communication protocol. The first software layer is an EPICS IOC module running as a computer server application capable of receiving requests from remote or local clients providing driver interface to the system by forwarding requested commands and receiving system and control operation status. The second software layer is the firmware running in Microchip dsPIC microcontroller modules which performs the interface from RS-232 optical fiber serial protocol to EPICS IOC module. The dsPIC module communicates to the ISTTOK tokamak sensors and actuators via RS-485 and is programmed with a new protocol developed for this purpose that allows EPICS IOC module command sending/receiving, machine operation control and monitoring and system status information. Communication between EPICS IOC module and clients is achieved via a TCP/IP and UDP protocol referred as Channel Access. In addition, the EPICS IOC module provides user client applications access allowing operators to perform remote or local monitoring, operation and control.

The TPS (Taiwan Photon Source) is the latest generation 3 GeV synchrotron light source which has been in construction since 2010. The EPICS (Experimental Physics and Industrial Control System) framework is adopted as control system infrastructure for the TPS. The EPICS IOCs (Input Output Controller) and various database records have been gradually implemented to control and monitor available subsystems of the TPS at this moment. The subsystem includes timing, power supply, motion controller, miscellaneous Ethernet compliant devices etc. Through EPICS PVs (Process Variables) channel access, remote access I/O data via Ethernet interface can be observed by the usable graphical tool-kits, such as the EDM (Extensible Display Manager) and MATLAB. The operation interface mainly includes the function of setting, reading, save, restore and etc. Integration of operation interfaces will depend upon properties of each subsystem. In addition, the centralized management method is utilized to serve every client from file servers in order to maintain consistent versions of related EPICS files. (authors)

Collaborative development of the EPICS Qt framework Phase I Final Report

Energy Technology Data Exchange (ETDEWEB)

Mayssat, Robert E. [Lyncean Technologies, Inc., Palo Alto, CA (United States)

2015-01-15

At Lyncean, a private company spun-off from technology developed at the SLAC National Lab, we have been using EPICS for over a decade. EPICS is ubiquitous on our flagship product – the Compact Light Source. EPICS is not only used to control our laser and accelerator systems, but also to control our x-ray beamlines. The goal of this SBIR is for Lyncean Technologies to spearhead a worldwide collaborative effort for the development of control system tools for EPICS using the Qt framework, a C++-based coding environment that could serve as a competitive alternative to the Java-based Control System Studio (CSS). This grant's Phase I, not unlike a feasibility study, is designed for planning and scoping the preparatory work needed for Phase II or other funding opportunities. The three main objectives of this Phase I are (1) to become better acquainted with the existing EPICS Qt software and Qt framework in order to evaluate the best options for ongoing development, (2) to demonstrate that our engineers can lead the EPICS community and jump-start the Qt collaboration, and (3) to identify a scope for our future work with solicited feedback from the EPICS community. This Phase I report includes key technical findings. It clarifies the differences between the two apparently-competing EPICS Qt implementations, caQtDM and the QE Framework; it explains how to create python-bindings, and compares Qt graphical libraries. But this report is also a personal story that narrates the birth of a collaboration. Starting a collaboration is not the work of a single individual, but the work of many. Therefore this report is also an attempt to publicly give credit to many who supported the effort. The main take-away from this grant is the successful birth of an EPICS Qt collaboration, seeded with existing software from the PSI and the Australian Synchrotron. But a lot more needs to be done for the collaboration founders' vision to be realized, and for the collaboration to reach

EPICS version 4 extends the functionality of version 3 by providing the ability to define, transport, and introspect composite data types. Version 3 provided a set of process variables and a data protocol that adequately defined scalar data along with an atomic set of attributes. While remaining backward compatible, Version 4 is able to easily expand this set with a data protocol capable of exchanging complex data types and parameterized data requests. Additionally, a group of engineers defined reference types for some applications in this environment. The goal of this work is to define a narrow interface with the minimal set of data types needed to support a distributed architecture for physics applications, data acquisition, and data analysis.

We report the discovery of two hot Jupiters orbiting the stars EPIC229426032 and EPIC246067459. We used photometric data from Campaign 11 and 12 of the Kepler K2 Mission and radial velocity data obtained using the HARPS, FEROS, and CORALIE spectrographs. EPIC229426032 b and EPIC246067459 b have masses of 1.60^{+0.11}_{-0.11} and 0.86^{+0.13}_{-0.12}Mjup, radii of 1.65^{+0.07}_{-0.08} and 1.30^{+0.15}_{-0.14} R_{jup}, and are orbiting their host stars in 2.18 and 3.20-day orbits, respectively. The large radius of EPIC229426032 b leads us to conclude that this candidate corresponds to a highly inflated hot Jupiter. EPIC2460674559 b has a radius consistent with theoretical models, considering the high incident flux falling on the planet. We consider EPIC229426032 b to be a excellent system for follow-up studies, since not only is it very inflated, but it also orbits a relatively bright star (V = 11.6).

To describe a validated and multifactorial deprivation score to study the relationship between socioeconomic deprivation and perinatal risks. The index of deprivation EPICES (Evaluation of Precarity and Inequalities in Health Examination Centers) was used to characterize the deprivation status of 234 women in post-partum in comparison with perinatal morbidity. The cutoff value of 30.7 was the threshold to define deprivation. Two hundred and eight patients were included in this retrospective study from whom 48 (23%) had a score of deprivation higher than 30.7. Maternofetal morbidity was more severe in deprived patients. The current results show that the EPICES score could be a useful obstetrical tool for the identification of deprived women during pregnancy. Copyright © 2011 Elsevier Masson SAS.

EPIC: an Error Propagation/Inquiry Code

International Nuclear Information System (INIS)

Baker, A.L.

1985-01-01

The use of a computer program EPIC (Error Propagation/Inquiry Code) will be discussed. EPIC calculates the variance of a materials balance closed about a materials balance area (MBA) in a processing plant operated under steady-state conditions. It was designed for use in evaluating the significance of inventory differences in the Department of Energy (DOE) nuclear plants. EPIC rapidly estimates the variance of a materials balance using average plant operating data. The intent is to learn as much as possible about problem areas in a process with simple straightforward calculations assuming a process is running in a steady-state mode. EPIC is designed to be used by plant personnel or others with little computer background. However, the user should be knowledgeable about measurement errors in the system being evaluated and have a limited knowledge of how error terms are combined in error propagation analyses. EPIC contains six variance equations; the appropriate equation is used to calculate the variance at each measurement point. After all of these variances are calculated, the total variance for the MBA is calculated using a simple algebraic sum of variances. The EPIC code runs on any computer that accepts a standard form of the BASIC language. 2 refs., 1 fig., 6 tabs

The CEBAF accelerator control system: migrating from a TACL to an EPICS based system

1994-01-01

CEBAF is in the process of migrating its accelerator and experimental hall control systems to one based upon EPICS, a control system toolkit developed by a collaboration among several DOE laboratories in the US. The new system design interfaces existing CAMAC hardware via a CAMAC serial highway to VME-based I/O controllers running the EPICS software; future additions and upgrades will for the most part go directly into VME. The decision to use EPICS followed difficulties in scaling the CEBAF-developed TACL system to full machine operation. TACL and EPICS share many design concepts, facilitating the conversion of software from one toolkit to the other. In particular, each supports graphical entry of algorithms built up from modular code, graphical displays with a display editor, and a client-server architecture with name-based I/O. During the migration, TACL and EPICS will interoperate through a socket-based I/O gateway. As part of a collaboration with other laboratories, CEBAF will add relational database support for system management and high level applications support. Initial experience with EPICS is presented, along with a plan for the full migration which is expected to be finished next year. ((orig.))

In line with our group's intention of producing software using, where possible, Object-Oriented methodologies and techniques in the development of RF control systems, we have undertaken three projects to enhance the EPICS software environment. Two of the projects involve interfaces to EPICs Channel Access from Object-Oriented languages. The third is an enhancement to the EPICS State Notation Language to better support the Shlaer-Mellor Object-Oriented Analysis and Design Methodology. This paper discusses the motivation, approaches, results and future directions of these three projects.

An EPICS IOC builder

International Nuclear Information System (INIS)

Abbott, M.G.; Cobb, T.

2012-01-01

An EPICS IOC (Input/Output Controller) is typically assembled from a number of standard components each with potentially quite complex hardware or software initialization procedures intermixed with a good deal of repetitive boiler-plate code. Assembling and maintaining a complex IOC can be a quite difficult and error prone process, particularly if the components are unfamiliar. The EPICS IOC builder is a Python library designed to automate the assembly of a complete IOC from a concise component level description. The dependencies and interactions between components as well as their detailed initialization procedures are automatically managed by the IOC builder through component description files maintained with the individual components. At Diamond Light Source we have a large library of components that can be assembled into EPICS IOCs. The IOC Builder is further finding increasing use in helping non-expert users to assemble an IOC without specialist knowledge. (authors)

The combined meteorology and air quality modeling system composed of the Weather Research and Forecast (WRF) model and Community Multiscale Air Quality (CMAQ) model is an important decision support tool that is used in research and regulatory decisions related to emissions, meteorology, climate, and chemical transport. The Environmental Policy Integrated Climate (EPIC) is a cropping model which has long been used in a range of applications related to soil erosion, crop productivity, climate change, and water quality around the world. We have integrated WRF/CMAQ with EPIC using the Fertilizer Emission Scenario Tool for CMAQ (FEST-C) to estimate daily soil N information with fertilization for CMAQ bi-directional ammonia flux modeling. Driven by the weather and N deposition from WRF/CMAQ, FEST-C EPIC simulations are conducted on 22 different agricultural production systems ranging from managed grass lands (e.g. hay and alfalfa) to crop lands (e.g. corn grain and soybean) with rainfed and irrigated information across any defined conterminous United States (U.S.) CMAQ domain and grid resolution. In recent years, this integrated system has been enhanced and applied in many different air quality and ecosystem assessment projects related to land-water-atmosphere interactions. These enhancements have advanced this system to become a valuable tool for integrated assessments of air, land and water quality in light of social drivers and human and ecological outcomes. This presentation will focus on evaluating the sensitivity of precipitation and N deposition in the integrated system to MODIS vegetation input and lightning assimilation and their impacts on agricultural production and fertilization. We will describe the integrated modeling system and evaluate simulated precipitation and N deposition along with other weather information (e.g. temperature, humidity) for 2011 over the conterminous U.S. at 12 km grids from a coupled WRF/CMAQ with MODIS and lightning assimilation

EPICS channel access using websocket

International Nuclear Information System (INIS)

Uchiyama, A.; Furukawa, K.; Higurashi, Y.

2012-01-01

Web technology is useful as a means of widely disseminating accelerator and beam status information. For this purpose, WebOPI was implemented by SNS as a web-based system using Ajax (asynchronous JavaScript and XML) with EPICS. On the other hand, it is often necessary to control the accelerator from different locations as well as the central control room during beam operation and maintenance. However, it is not realistic to replace the GUI-based operator interface (OPI) with a Web-based system using Ajax technology because of interactive performance issue. Therefore, as a next generation OPI over the web using EPICS Channel Access (CA), we developed a client system based on WebSocket, which is a new protocol provided by the Internet Engineering Task Force (IETF) for Web-based systems. WebSocket is a web technology that provides bidirectional, full-duplex communication channels over a single TCP connection. By utilizing Node.js and the WebSocket access library called Socket.IO, a WebSocket server was implemented. Node.js is a server-side JavaScript language built on the Google V8 JavaScript Engine. In order to construct the WebSocket server as an EPICS CA client, an add-on for Node.js was developed in C/C++ using the EPICS CA library, which is included in the EPICS base. As a result, for accelerator operation, Web-based client systems became available not only in the central control room but also with various types of equipment. (author)

The Expanded Prostate Cancer Index Composite (EPIC) instrument was designed to assess a range of health-related quality-of-life issues specifically relevant to patients with prostate cancer. This study examined the validity and reliability of Chinese versions of the 26-item EPIC and of the 16-item EPIC for Clinical Practice (EPIC-CP) in Chinese patients with prostate cancer. A Chinese version of the 26-item EPIC and the 16-item EPIC-CP were self-completed by 252 Chinese patients with prostate cancer who were recruited from three community-based cancer service centers. Confirmatory factors analysis assessed the factor structures of the EPIC and the EPIC-CP. Internal consistency and construct and clinical validities of the factor structures were assessed. Confirmatory factor analysis revealed that the original factor structure of both EPIC-26 and EPIC-CP showed good fit to this sample. A correlated model was superior to a hierarchical model in both EPIC-26 and EPIC-CP supporting the utility of the domain scores over the total scores. Cronbach α ranged from 0.55 to 0.91 for EPIC-26 and 0.44 to 0.67 for EPIC-CP. Construct validity was supported by correlations between EPIC-26/EPIC-CP and psychological distress measures. Clinical validity was supported by differentiation between patients with and without prostatectomy. These Chinese versions of the five-factor EPIC-26 and the EPIC-CP are valid and practical measures for assessing a range of health-related quality-of-life issues related to the diagnosis and treatment of prostate cancer, highlighting their utility in assessing health-related quality of life for patients diagnosed with prostate cancer.

The Experimental Physics and Industrial Control System (EPICS) is a software toolkit, developed by a worldwide collaboration, which significantly reduces the level of effort required to implement a new control system. Recent developments now also significantly reduce the level of effort required to integrate commercial, legacy and/or site-authored control systems with EPICS. This paper will illustrate with an example both the level and type of effort required to use EPICS with other control system components as well as the benefits that may arise

The rebirth of the epic from the Nietzsche's Philosophy

Reza Samim

2016-12-01

Full Text Available his philosophy with Iranian mysticism. Such identification is fundamentally flawed and contradicts Nietzsche's ontological principles and moral values. Some of the Iranian commentators, expert in Nietzsche's philosophy, identified Nietzsche's thought is pregnant from the epic universal values, not the mystical patterns. Understanding of Nietzsche's Philosophy is possible with the help of Shahnameh and Iliad not mysticism. The reason of this fundamental error lies in the fact that these Iranian commentators fail to distinguish the subtle differences between mysticism and epic, and this failure, has led to their mixing Nietzsche's thought with the Iranian mysticism. Epic and mysticism are related in the differences not the similarities. Although there could be some similarities between the mystical worldview and that of epic, they are merely outward and superficial. In effect, in the matter of epistemic, moral and ontological principles, epic contradicts mysticism. At the best, mysticism can be considered to be the negative correspondence of epic and called “Negative Epic”. Nietzsche's thought has been affected to a greater extent by the Greek culture than and prior to the Iranian traditions. Nietzche's symbolic recourse to Zoroaster cannot be a cogent basis for these commentators' claim. Moreover, Nietzche's grasp of Zoroastrian worldview is so much blurred and incomplete. He appreciates the Greek culture not the Iranian traditions. Therefore, autonomy, voluntarism, appreciation of life and denunciation of passivity are the set of values and principles associating Nietzsche's philosophy with epic. These are exactly the principles disregarded and even denied in mystical thought. In other words, Nietzsche's philosophy can be considered the rebirth of the epic in the sphere of philosophical thought.

The Advanced Photon Source (APS) at Argonne National Laboratory is a third-generation x-ray light source which uses the Experimental Physics and Industrial Control System (EPICS) to operate its linear accelerator, positron accumulator ring, booster synchrotron, and storage ring equipment. EPICS has been used at the APS since the beginning of installation and commissioning. Currently, EPICS controls approximately 100 VME crates containing over 100,000 process variables. With this complexity, the APS has had to review some of the methods originally employed and make changes as necessary. In addition, due to commissioning and operational needs, higher-level operator software needed to be created. EPICS has been flexible enough to allow this

On the Issue of Origin of the Yakut Epic Olonkho

2018-03-01

Full Text Available The issue on the origin of the Yakut heroic epic Olonkho was covered in works in history and ethnography of the Yakuts back in the 19th century, for instance, in the famous monograph Yakuts. Experience of ethnographic research by a Polish exile V.L. Seroshevskiy (1896. Since that time, this issue was interesting for many, but no special monograph research has been done yet. Currently, the issue of Olonkho origin is gaining special scientific and general cultural significance, as on November 25, 2005 the Yakut heroic epic Olonkho according to the historical decision of UNESCO was granted the high status “Masterpiece of oral and non-material heritage of humanity”. The Yakut epic is a part of the multicomponent epic creative work of the Turkic nations but it was the only one to get such a high international recognition. This paper aims to revive the scientific interest to the issue of the Yakut epic’s genesis. To date, some rich source-related and historiographical material has been accumulated for broader generalizations – the main point is that the Yakut epic is becoming an important object of comparative historical analysis of the origin of all Turkic epics. The thing is that epic researchers admit that almost a thousand years of existence isolated from the whole Turkic world in the North-East of Asia kept many archaic features of the epics of the ancient ancestors – natives of Central Asia and Southern Siberia. It became clear that Olonkho origin is organically linked with the ethnic history of its nation.The paper follows this comprehensive process reflected in works by archeologists, ethnographers, historians and linguists. Their latest achievements are impressive, bringing a lot of novelty into the conventional views of origins and development of the Yakut epic. The paper attempts to specify that novelty and rationalize the idea that time has come to introduce that novelty into science to solve the long-standing issue of origin of

Full Text Available In 2004 Hollywood produced three purportedly blockbuster epic films:Troy, King Arthur and Alexander. Many critics suggested a direct linkbetween the 1950s “sword and sandal” epic and this new crop of movies.Similarities between the two cycles certainly exist but in this essay I want to emphasize a crucial difference between the contemporary,cosmopolitan, epic and the previous, more nation-bound, 1950s cycle.Rather than being in tune with key elements of American foreign policy, the new cycle of “sword and sandal” films offers a somber assessment of American imperial adventures. I shall contend, in fact, that the new crop of epic films had to choose between two generic conventions that are, at present, not compatible. On the one hand, epic films had traditionally been the bearers of the foreign policy vision of the country that produced them. On the other, their inflated budgets made them dependent on an international market. Deeply aware of a globalized and rising opposition to US foreign policy and of the fact that foreign box office now exceeds the domestic take of a blockbuster, it may be no wonder that the makers of these films chose to craft them into citizens of the world.

SPIDER, the ITER-size ion-source test bed in the ITER Neutral Beam Test Facility, is a fusion device requiring a complex central system to provide control and data acquisition, referred to as CODAS. The CODAS software architecture will rely on EPICS and MDSplus, two open-source, collaborative software frameworks, targeted at control and data acquisition, respectively. EPICS has been selected as ITER CODAC middleware and, as the final deliverable of the Neutral Beam Test Facility is the procurement of the ITER Heating Neutral Beam Injector, we decided to adopt this ITER technology. MDSplus is a software package for data management, supporting advanced concepts, such as platform and underlying hardware independence, self description data, and data driven model. The combined use of EPICS and MDSplus is not new in fusion, but their level of integration will be new in SPIDER, achieved by a more refined data access layer. The paper presents the integration software to use effectively EPICS and MDSplus, including the definition of appropriate EPICS records to interact with MDSplus. The MDSplus and EPICS archive concepts are also compared on the basis of performance tests and data streaming is investigated by ad-hoc measurements.

EPICS (Experimental Physics and Industrial Control System) is a collection of software tools collaboratively developed which can be integrated to provide a comprehensive and scalable control system. Currently there is an increase in use of such systems in large Physics experiments like KSTAR, ITER and DAIC (Daejeon Accelerator Ion Complex). The Korean heat load test facility (KoHLT-EB) was installed at KAERI. This facility is utilized for a qualification test of the plasma facing component (PFC) for the ITER first wall and DEMO divertor, and the thermo-hydraulic experiments. The existing data acquisition device was Agilent 34980A multifunction switch and measurement unit and controlled by Agilent VEE. In the present paper, we report the EPICS based newly upgraded KoHLT-EB DAQ system which is the advanced data acquisition system using FPGA-based reconfigurable DAQ devices like compact RIO. The operator interface of KoHLT-EB DAQ system is composed of Control-System Studio (CSS) and another server is able to archive the related data using the standalone archive tool and the archiveviewer can retrieve that data at any time in the infra-network.

The Earth Polychromatic Imaging Camera (EPIC) sensor on the Deep Space Climate Observatory (DSCOVR) satellite presents unique opportunities to derive cloud properties of the entire daytime Earth. In particular, the Oxygen A- and B-band and corresponding reference channels provide cloud top pressure information. In order to address the in-cloud penetration depth issue—and ensuing retrieval bias—a comprehensive sensitivity study has been conducted to simulate satellite-observed radiances for a wide variety of cloud structures and optical properties. Based on this sensitivity study, a cloud top pressure algorithm for DSCOVR-EPIC has been developed. Further, the algorithm has been applied to EPIC measurements.

Simulation using Xorbit with EPICS

International Nuclear Information System (INIS)

Evans, K. Jr.

1995-01-01

The accelerator code Xorbit has an interface to the Experimental Physics and Industrial Control System (EPICS). This means that machine data such as magnet settings can be sent to Xorbit via EPICS, and the resulting orbit parameters such as beta functions, etc., can be calculated. In addition, Xorbit can be made to simulate the real machine, whether the latter is running or not. To accomplish this for the APS, there is a database of process variables in an IOC corresponding to each APS ring and beamline. These process variables are very similar to the real process variables that read and set power supplies and read monitors, except that when a setting is changed, Xorbit is notified via a callback, calculates a new orbit, and outputs the appropriate readbacks to the database. By attaching the string ''Xorbit:'' to a control name the control system will respond to the simulation rather than the real system. This allows the testing of control algorithms, orbit diagnostics, and many other components of the control system (as well as EPICS itself). It is fast enough to be visually similar to accessing the real system

Exon-primed intron-crossing (EPIC markers for non-model teleost fishes

Directory of Open Access Journals (Sweden)

Riethoven Jean-Jack M

2010-03-01

Full Text Available Abstract Background Exon-primed intron-crossing (EPIC markers have three advantages over anonymous genomic sequences in studying evolution of natural populations. First, the universal primers designed in exon regions can be applied across a broad taxonomic range. Second, the homology of EPIC-amplified sequences can be easily determined by comparing either their exon or intron portion depending on the genetic distance between the taxa. Third, having both the exon and intron fragments could help in examining genetic variation at the intraspecific and interspecific level simultaneously, particularly helpful when studying species complex. However, the paucity of EPIC markers has hindered multilocus studies using nuclear gene sequences, particularly in teleost fishes. Results We introduce a bioinformatics pipeline for developing EPIC markers by comparing the whole genome sequences between two or more species. By applying this approach on five teleost fishes whose genomes were available in the Ensembl database http://www.ensembl.org, we identified 210 EPIC markers that have single-copy and conserved exon regions with identity greater than 85% among the five teleost fishes. We tested 12 randomly chosen EPIC markers in nine teleost species having a wide phylogenetic range. The success rate of amplifying and sequencing those markers varied from 44% to 100% in different species. We analyzed the exon sequences of the 12 EPIC markers from 13 teleosts. The resulting phylogeny contains many traditionally well-supported clades, indicating the usefulness of the exon portion of EPIC markers in reconstructing species phylogeny, in addition to the value of the intron portion of EPIC markers in interrogating the population history. Conclusions This study illustrated an effective approach to develop EPIC markers in a taxonomic group, where two or more genome sequences are available. The markers identified could be amplified across a broad taxonomic range of teleost

An object oriented framework of EPICS for MicroTCA based control system

Geng, Z.

2012-01-01

EPICS (Experimental Physics and Industrial Control System) is a distributed control system platform which has been widely used for large scientific devices control like particle accelerators and fusion plant. EPICS has introduced object oriented (C ++ ) interfaces to most of the core services. But the major part of EPICS, the run-time database, only provides C interfaces, which is hard to involve the EPICS record concerned data and routines in the object oriented architecture of the software. This paper presents an object oriented framework which contains some abstract classes to encapsulate the EPICS record concerned data and routines in C ++ classes so that full OOA (Objected Oriented Analysis) and OOD (Object Oriented Design) methodologies can be used for EPICS IOC design. We also present a dynamic device management scheme for the hot swap capability of the MicroTCA based control system. (authors)

The Earth Polychromatic Imaging Camera (EPIC) aboard the Deep Space Climate Observatory (DSCOVR) satellite constantly images the sunlit disk of Earth from the Lagrange-1 (L1) point in 10 spectral channels spanning the UV, VIS, and NIR spectrums. Recently, the DSCOVR EPIC team has publicly released version 2 dataset, which has implemented improved navigation, stray-light correction, and flat-fielding of the CCD array. The EPIC 2-year data record must be well-calibrated for consistent cloud, aerosol, trace gas, land use and other retrievals. Because EPIC lacks onboard calibrators, the observations made by EPIC channels must be calibrated vicariously using the coincident measurements from radiometrically stable instruments that have onboard calibration systems. MODIS and VIIRS are best-suited instruments for this task as they contain similar spectral bands that are well-calibrated onboard using solar diffusers and lunar tracking. We have previously calibrated the EPIC version 1 dataset by using EPIC and VIIRS angularly matched radiance pairs over both all-sky ocean and deep convective clouds (DCC). We noted that the EPIC image required navigations adjustments, and that the EPIC stray-light correction provided an offset term closer to zero based on the linear regression of the EPIC and VIIRS ray-matched radiance pairs. We will evaluate the EPIC version 2 navigation and stray-light improvements using the same techniques. In addition, we will monitor the EPIC channel calibration over the two years for any temporal degradation or anomalous behavior. These two calibration methods will be further validated using desert and DCC invariant Earth targets. The radiometric characterization of the selected invariant targets is performed using multiple years of MODIS and VIIRS measurements. Results of these studies will be shown at the conference.

2009-01-01

The Extrasolar Planetary Imaging Coronagraph (EPIC) is a proposed NASA Exoplanet Probe mission to image and characterize extrasolar giant planets. EPIC will provide insights into the physical nature and architecture of a variety of planets in other solar systems. Initially, it will detect and characterize the atmospheres of planets identified by radial velocity surveys, determine orbital inclinations and masses and characterize the atmospheres around A and F type stars which cannot be found with RV techniques. It will also observe the inner spatial structure of exozodiacal disks. EPIC has a heliocentric Earth trailing drift-away orbit, with a 5 year mission lifetime. The robust mission design is simple and flexible ensuring mission success while minimizing cost and risk. The science payload consists of a heritage optical telescope assembly (OTA), and visible nulling coronagraph (VNC) instrument. The instrument achieves a contrast ratio of 10^9 over a 5 arcsecond field-of-view with an unprecedented inner working angle of 0.13 arcseconds over the spectral range of 440-880 nm. The telescope is a 1.65 meter off-axis Cassegrain with an OTA wavefront error of lambda/9, which when coupled to the VNC greatly reduces the requirements on the large scale optics.

A new EPICS/RTEMS IOC based on the Altera System-on-Chip (SoC) FPGA is being designed at Jefferson Lab. The Altera SoC FPGA integrates a dual ARM Cortex-A9 Hard Processor System (HPS) consisting of processor, peripherals and memory interfaces tied seamlessly with the FPGA fabric using a high-bandwidth interconnect backbone. The embedded Altera SoC IOC has features of remote network boot via U-Boot from SD card or QSPI Flash, 1Gig Ethernet, 1GB DDR3 SDRAM on HPS, UART serial ports, and ISA bus interface. RTEMS for the ARM processor BSP were built with CEXP shell, which will dynamically load the EPICS applications at runtime. U-Boot is the primary bootloader to remotely load the kernel image into local memory from a DHCP/TFTP server over Ethernet, and automatically run RTEMS and EPICS. The first design of the SoC IOC will be compatible with Jefferson Lab’s current PC104 IOCs, which have been running in CEBAF 10 years. The next design would be mounting in a chassis and connected to a daughter card via standard HSMC connectors. This standard SoC IOC will become the next generation of low-level IOC for the accelerator controls at Jefferson Lab.

Highlights: • Implementation of a soft real-time control system based on EPICS technology. • High data throughput system control implementation. • GPU technology applied to fast control. • EPICS fast control based solution. • Fast control and data acquisition in Linux. - Abstract: For new control systems development, ITER distributes CODAC Core System that is a software package based on Linux RedHat, and includes EPICS (Experimental Physics and Industrial Control System) as software control system solution. EPICS technology is being widely used for implementing control systems in research experiments and it is a very well tested technology, but presents important lacks to meet fast control requirements. To manage and process massive amounts of acquired data, EPICS requires additional functions such as: data block oriented transmissions, links with speed-optimized data buffers and synchronization mechanisms not based on system interruptions. This EPICS limitation turned out clearly during the development of the Fast Plant System Controller Prototype for ITER based on PXIe platform. In this work, we present a solution that, on the one hand, is completely compatible and based on EPCIS technology, and on the other hand, extends EPICS technology for implementing high performance fast control systems with soft-real time characteristics. This development includes components such as: data acquisition, processing, monitoring, data archiving, and data streaming (via network and shared memory). Additionally, it is important to remark that this system is compatible with multiple Graphics Processing Units (GPUs) and is able to integrate MatLab code through MatLab engine connections. It preserves EPICS modularity, enabling system modification or extension with a simple change of configuration, and finally it enables parallelization based on data distribution to different processing components. With the objective of illustrating the presented solution in an actual

Full Text Available The aim of this study is to show the presence of classical epic, Homer's Iliad, in the chronicle of Machado de Assis, analyzing the intertextual dialogue between Machado de Assis and the epic poem by Homer, considering the concept of intertextuality developed by Julia Kristeva from philosophical conceptions of Bakhtin. In the chronicle of March 18, 1894 for the newspaper Gazeta de Notícias on sunday column "A Semana", Machado de Assis crosses Homer's epic to his chronicle, rewrites the epic text for the daily issues of his weekly column. To Tiphaine Samoyault, writing is rewriting, "stand on the existing foundations and contribute to a continued creation" (2008, p. 77 one of the principles of intertextuality. It was observed that from the reading and assimilation of the classic poem, Machado de Assis can approach so far genres, bringing the verses to his prose, leaving it closer to poetry. In this sense, we can see the richness of Machado de Assis chronicles, often left on the sidelines in favor of his short stories and romances. In addition, the dialogue, to rewrite the epic in his chronicle, Machado seems to contribute to this "continuous creation", reviving the memory of literature and emphasizing the permanence of classical work.

Pirate Alterity and Mimesis in Colonial Epic Poetry

Full Text Available Pirate representation is studied in a series of Epic poems in the late sixteenth century and early seventeenth century. The ambiguous image of the English enemy is read in texts by Juan de Miramontes, Pedro de Oña, Martín del Barco Centenera and Juan de Castellanos, among others. On the one hand, Colonial Epic ignores some important differences between privateers and pirates since the privateering had been legally accepted by all European nations, including Spain. Besides, Pirate is always called «Lutheran» and revealing its absolute otherness with respect to the Catholic model. On the other hand, it proposes a laudatory epics enemy painting from the imitation of the values accepted by the colonial society. The relationship between the Spanish hero and the privateer is represented not in a vertical direction, as could happen between colonizer and colonized subject, but on a level of rivalry.

2011-02-01

J-PARC (Japan Proton Accelerator Research Complex) accelerator devices are controlled by the use of the software called EPICS (Experimental Physics and Industrial Control System). The unique name called an EPICS record is given to a control signal and data acquisition, Accelerator device control is achieved using the EPICS record. The requirement for the EPICS record name is 2 points; (1) no overlap of the EPICS record name, (2) the control contents can be easily imagined from the EPICS record name. To manage the EPICS record using relational database for the information management of the accelerator device in J-PARC, the naming structure is required so that a mechanical process can be performed easily. It was necessary to standardize the EPICS record name and the EPICS record structure to achieve these requirements. Therefore, we have formulated a guideline called 'EPICS record naming conventions' to decide to an EPICS record name uniquely and standardization. The abbreviated key word list of the accelerator devices and the control signal that compose the EPICS record name is appended to the EPICS record naming conventions. (author)

The trio of macromolecular crystallography beamlines constructed by the General Medicine and Cancer Institutes Collaborative Access Team (GM/CA-CAT) in Sector 23 of the Advanced Photon Source (APS) have been in growing demand owing to their outstanding beam quality and capacity to measure data from crystals of only a few micrometres in size. To take full advantage of the state-of-the-art mechanical and optical design of these beamlines, a significant effort has been devoted to designing fast, convenient, intuitive and robust beamline controls that could easily accommodate new beamline developments. The GM/CA-CAT beamline controls are based on the power of EPICS for distributed hardware control, the rich Java graphical user interface of Eclipse RCP and the task-oriented philosophy as well as the look and feel of the successful SSRL BluIce graphical user interface for crystallography. These beamline controls feature a minimum number of software layers, the wide use of plug-ins that can be written in any language and unified motion controls that allow on-the-fly scanning and optimization of any beamline component. This paper describes the ways in which BluIce was combined with EPICS and converted into the Java-based JBluIce, discusses the solutions aimed at streamlining and speeding up operations and gives an overview of the tools that are provided by this new open-source control system for facilitating crystallographic experiments, especially in the field of microcrystallography.

The Low-Level RF (LLRF) control system of the Proton Engineering Frontier Project (PEFP) was developed for handling the driving frequency for Quadrupole (RFQ) and the Draft Tube Linac (DTL) cavities in 2006. The RF amplitude and phase of the accelerating field were controlled within 1% and 1 degree by stability requirements, respectively. Operators have been using the LLRF control system under the windows based text console mode as an operator interface. The LLRF control system could not be integrated with Experimental Physics Industrial Control System (EPICS) Input Output Controllers (IOC) for each subsection of PEFP facility.

The control system of SSRF (Shanghai Synchrotron Radiation Facility) is based on EPICS (Experimental Physics and Industrial Control System). Operation data storage for synchrotron radiation facility is important for its status monitoring and analysis. At SSRF, operation data used to be index files recorded by traditional EPICS Channel Archiver. Nevertheless, index files are not suitable for long-term maintenance and difficult for data analysis. Now, RDB Channel Archiver and MySQL are used for SSRF beamline operation data archiving, so as to promote the data storage reliability and usability. By applying a new uploading mechanism to RDB Channel Archiver, its writing performance is improved. A web-based GUI (Graphics User Interface) is also developed to make it easier to access database.

Basu, A.; Singh, S.K.; Rosily, Sherry; Bhagwat, P.V.

2016-01-01

Particle accelerators and many industrial complex systems, require a robust and efficient control for its proper operation to achieve required beam quality, safety of its sub component and all working personnel. This control is executed via a graphical user interface through which an operator interacts with the accelerator to achieve the desired state of the machine and its output. Experimental Physics and Industrial Control System (EPICS) is a widely used control system framework in the field of accelerator control. It acts as a middle layer between field devices and graphic user interface used by the operator. Field devices can also be made EPICS compliant by using EPICS based software in that. On the other hand Qt is a C++ framework which is widely used for creating very professional looking and user friendly graphical component. In Low Energy High Intensity Proton Accelerator (LEHIPA), which is the first stage of the three stage Accelerator Driven System (ADS) program taken by Bhabha Atomic Research Centre (BARC), it is decided that EPICS will be used for controlling the accelerator and Qt will be used for developing the various Graphic User Interface (GUI) for operation and diagnostics. This paper discuss the work carried out to achieve this goal in LEHIPA

The Experimental Physics and Industrial Control System (EPICS) uses a broadcast method to locate resources and controls distributed across control servers. There are many advantages offered by using a centrally managed name resolution method, in which resources are located using a repository. The suitability of DCE Directory Service as a name resolution method is explored, and results from a study involving DCE are discussed. An alternative nameserver method developed and in use at the Thomas Jefferson national Accelerator Facility (Jefferson Lab) is described and results of integrating this new method with existing EPICS utilities presented. The various methods discussed in the paper are compared

The beam loss signals must be digitized and the sampling has to be synchronized to a reference signal which is an external trigger for beam operation. The digitized data must be accessible by the Experimental Physics and Industrial Control System (EPICS)-based control system, which manages the whole accelerator control. In order to satisfy the requirement, an Input /Output Controller (IOC), which runs Linux on a CPU module with PCI express based Analog to Digital Converter (ADC) modules, has been adopted. An associated linux driver and EPICS device support module also have been developed. The IOC meets the requirements and the development and maintenance of the software for the IOC is considerably efficient. The data acquisition system running EPICS will be used in increasing phase of KOrea Multi-purpose Accelerator Complex (KOMAC) beam power. The beam monitoring system integrates BLM and BPM signals into control system and offers real-time data to operators. The IOC, which is implemented with Linux and PCI driver, has supported data acquisition as a very flexible solution.

To identify new tools capable of predicting surgical performance of novices on an augmentation mammoplasty simulator. The pace of technical skills acquisition varies between residents and may necessitate more time than that allotted by residency training before reaching competence. Identifying applicants with superior innate technical abilities might shorten learning curves and the time to reach competence. The objective of this study is to identify new tools that could predict surgical performance of novices on a mammoplasty simulator. We recruited 14 medical students and recorded their performance in 2 skill-games: Mikado and Perplexus Epic, and in 2 video games: Star War Racer (Sony Playstation 3) and Super Monkey Ball 2 (Nintendo Wii). Then, each participant performed an augmentation mammoplasty procedure on a Mammoplasty Part-task Trainer, which allows the simulation of the essential steps of the procedure. The average age of participants was 25.4 years. Correlation studies showed significant association between Perplexus Epic, Star Wars Racer, Super Monkey Ball scores and the modified OSATS score with r s = 0.8491 (p 41 (p = 0.005), and r s = 0.7309 (p < 0.003), but not with the Mikado score r s = -0.0255 (p = 0.9). Linear regressions were strongest for Perplexus Epic and Super Monkey Ball scores with coefficients of determination of 0.59 and 0.55, respectively. A combined score (Perplexus/Super-Monkey-Ball) was computed and showed a significant correlation with the modified OSATS score having an r s = 0.8107 (p < 0.001) and R 2 = 0.75, respectively. This study identified a combination of skill games that correlated to better performance of novices on a surgical simulator. With refinement, such tools could serve to help screen plastic surgery applicants and identify those with higher surgical performance predictors.

Knott, M.; Gurd, D.; Lewis, S.; Thuot, M.

1993-01-01

The Experimental Physics and Industrial Control Systems (EPICS) is the result of a software sharing and co-development effort of major importance now underway. The initial two participants, LANL and ANL, have now been joined by three other labs, and an earlier version of the software has been transferred to three commercial firms and is currently undergoing separate development. The reasons for EPICS's success may be useful to enumerate and explain and the desire and prospects for its continued development are certainly worth examining

CAFE, a modern C++ interface to the EPICS channel access library

International Nuclear Information System (INIS)

Chrin, J.; Sloan, M.C.

2012-01-01

CAFE (Channel Access interface) is a C++ library that provides a modern, multifaceted interface to the EPICS-based control system that we may find in particle accelerators for instance. CAFE makes extensive use of templates and containers with multiple STL-compatible access methods to enhance efficiency, flexibility and performance. Stability and robustness are accomplished by ensuring that connectivity to EPICS channels remains in a well defined state in every eventuality, and results of all synchronous and asynchronous operations are captured and reported with integrity. CAFE presents the user with a number of options for writing and retrieving data to and from the control system. In addition to basic read and write operations, a further abstraction layer provides transparency to more intricate functionalities involving logical sets of data; such 'group' objects are easily instantiated through an XML-based configuration mechanism. CAFE's suitability for use in a broad spectrum of applications is demonstrated. These range from high performance Qt GUI (Graphical User Interface) control widgets, to event processing agents that propagate data through the Object Managements Group's Data Distribution Service (OMG-DDS), to script-like frameworks such as MATLAB. The methodology for the modular use of CAFE serves to improve maintainability by enforcing a logical boundary between the channel access components and the programming extensions of the application framework at hand.

The Extrasolar Planetary Imaging Coronagraph (EPIC) is a NASA Astrophysics Strategic Mission Concept under study for the upcoming Exoplanet Probe. EPIC's mission would be to image and characterize extrasolar giant planets, and potential super-Earths, in orbits with semi-major axes between 2 and 10 AU. EPIC will provide insights into the physical nature of a variety of planets in other solar systems complimenting radial velocity (RV) and astrometric planet searches. It will detect and characterize the atmospheres of planets identified by radial velocity surveys and potentially some transits, determine orbital inclinations and masses, characterize the atmospheres of gas giants around A and F stars, observed the inner spatial structure and colors of inner Spitzer selected debris disks. EPIC would be launched into a heliocentric Earth trailing drift-away orbit, with a 3-year mission lifetime (5 year goal) and will revisit planets at least three times. The starlight suppression approach consists of a visible nulling coronagraph (VNC) that enables high order starlight suppression in broadband light. To demonstrate the VNC approach and advance it's technology readiness the NASA/Goddard Space Flight Center and Lockheed-Martin have developed a laboratory VNC and have demonstrated white light nulling. We will discuss our ongoing VNC work and show the latest results from the VNC testbed.

Development of EPICS based beam-line experimental control employing motor controller for precision positioning

Tuli, Anupriya; Jain, Rajiv; Vora, H.S.

2015-01-01

In a Synchrotron Radiation Source the beamline experiments are carried out in radiation prone environment, inside the hutch, which demands to conduct experiments remotely. These experiments involves instrument control and data acquisition from various devices. Another factor which attributes to system complexity is precise positioning of sample and placement of detectors. A large number of stepper motors are engaged for achieving the required precision positioning. This work is a result of development of Experimental Physics and Industrial Control System (EPICS) based control system to interface a stepper motor controller developed indigenously by Laser Electronics Support Division of RRCAT. EPICS is an internationally accepted open source software environment which follows toolkit approach and standard model paradigm. The operator interface for the control system software was implemented using CSS BOY. The system was successfully tested for Ethernet based remote access. The developed control software comprises of an OPI and alarm handler (EPICS ALH). Both OPI and ALH are linked with PV's defined in database files. The development process resulted into a set of EPICS based commands for controlling stepper motor. These commands are independent of operator interface, i.e. stepper motor can be controlled by using these set of commands directly on EPICS prompt. This command set is illustrated in the above table. EPICS Alarm Handler was also tested independently by running these commands on EPIC prompt. If not using ALH, operator can read the alarm status of a PV using 'SEVR' and 'STAT' attributes. (author)

2015-05-07

Few detailed facility-based costing studies of routine immunization (RI) programs have been conducted in recent years, with planners, managers and donors relying on older information or data from planning tools. To fill gaps and improve quality of information, a multi-country study on costing and financing of routine immunization and new vaccines (EPIC) was conducted in Benin, Ghana, Honduras, Moldova, Uganda and Zambia. This paper provides the rationale for the launch of the EPIC study, as well as outlines methods used in a Common Approach on facility sampling, data collection, cost and financial flow estimation for both the routine program and new vaccine introduction. Costing relied on an ingredients-based approach from a government perspective. Estimating incremental economic costs of new vaccine introduction in contexts with excess capacity are highlighted. The use of more disaggregated System of Health Accounts (SHA) coding to evaluate financial flows is presented. The EPIC studies resulted in a sample of 319 primary health care facilities, with 65% of facilities in rural areas. The EPIC studies found wide variation in total and unit costs within each country, as well as between countries. Costs increased with level of scale and socio-economic status of the country. Governments are financing an increasing share of total RI financing. This study provides a wealth of high quality information on total and unit costs and financing for RI, and demonstrates the value of in-depth facility approaches. The paper discusses the lessons learned from using a standardized approach, as well as proposes further areas of methodology development. The paper discusses how results can be used for resource mobilization and allocation, improved efficiency of services at the country level, and to inform policies at the global level. Efforts at routinizing cost analysis to support sustainability efforts would be beneficial. Copyright © 2015 Elsevier Ltd. All rights reserved.

Pedro Cebollero

2017-11-01

Full Text Available This is an introductory study to Gaspar de Villagrá’s History of New Mexico (1610 in the context of the Cortés epic cycle tradition. The concept of «epic continuity» is utilized in order to better understand how the poem adheres to epic tradition at the same time that it goes through formal changes needed for its renovation. Part of the renovation is the inclusion of prose as a legal defense strategy, and its use as a vehicle for the struggles of Mexican Creoles. It is proposed that this poem belongs in a Frontier Creole epic sub-cycle.

Matthew D Krasowski

2016-01-01

Full Text Available Background: Epic Beaker Clinical Pathology (CP is a relatively new laboratory information system (LIS operating within the Epic suite of software applications. To date, there have not been any publications describing implementation of Beaker CP. In this report, we describe our experience in implementing Beaker CP version 2012 at a state academic medical center with a go-live of August 2014 and a subsequent upgrade to Beaker version 2014 in May 2015. The implementation of Beaker CP was concurrent with implementations of Epic modules for revenue cycle, patient scheduling, and patient registration. Methods: Our analysis covers approximately 3 years of time (2 years preimplementation of Beaker CP and roughly 1 year after using data summarized from pre- and post-implementation meetings, debriefings, and the closure document for the project. Results: We summarize positive aspects of, and key factors leading to, a successful implementation of Beaker CP. The early inclusion of subject matter experts in the design and validation of Beaker workflows was very helpful. Since Beaker CP does not directly interface with laboratory instrumentation, the clinical laboratories spent extensive preimplementation effort establishing middleware interfaces. Immediate challenges postimplementation included bar code scanning and nursing adaptation to Beaker CP specimen collection. The most substantial changes in laboratory workflow occurred with microbiology orders. This posed a considerable challenge with microbiology orders from the operating rooms and required intensive interventions in the weeks following go-live. In postimplementation surveys, pathology staff, informatics staff, and end-users expressed satisfaction with the new LIS. Conclusions: Beaker CP can serve as an effective LIS for an academic medical center. Careful planning and preparation aid the transition to this LIS.

Highlights: • This architecture targets the health management integration into the NDS. • The developed solution supports the ShM redundancy features, specified by ATCA. • The average RTT was around 59 ms and in 99.9% of the cases was less than 130 ms. • Without losing any update cycle, can monitor a system shelf with approximately 400 sensors. • This solution enables the user to configure the entire system in DB files and st.cmd. - Abstract: The ITER CODAC Core System (CCS) is responsible for plant Instrumentation and Control (I&C) supervising and monitoring. This system uses the Enhanced Physics and Industrial Control System (EPICS) Channel Access (CA) protocol as the interface with the Plant Operation Network (PON). This paper presents a generic EPICS device support developed for the integration of the ATCA Shelf Manager (ShM) into the ITER CCS, providing scalability and easy configuration. The device support uses the available HTTP interface on Shelf Manager in the communication layer. Both HTTP server and sensors/actuators definitions can be configured using the EPICS database file and the Input/Output Controller (IOC) initialization file. A proposal based on this device is also presented, targeting the Nominal Device Support (NDS) for health management. The EPICS device support running in an IOC provides Process Variables (PV) to the PON network with the system information and these PVs can be used by all CA clients, such as EPICS user interface clients, alarm systems and archive systems. Operation with redundant ATCA ShMs and device support scalability tests were performed and the results are presented.

DSCOVR/EPIC observations of SO2 reveal dynamics of young volcanic eruption clouds

Volcanic emissions of sulfur dioxide (SO2) and ash have been measured by ultraviolet (UV) and infrared (IR) sensors on US and European polar-orbiting satellites since the late 1970s. Although successful, the main limitation of these observations from low Earth orbit (LEO) is poor temporal resolution (once per day at low latitudes). Furthermore, most currently operational geostationary satellites cannot detect SO2, a key tracer of volcanic plumes, limiting our ability to elucidate processes in fresh, rapidly evolving volcanic eruption clouds. In 2015, the launch of the Earth Polychromatic Imaging Camera (EPIC) aboard the Deep Space Climate Observatory (DSCOVR) provided the first opportunity to observe volcanic clouds from the L1 Lagrange point. EPIC is a 10-band spectroradiometer spanning UV to near-IR wavelengths with two UV channels sensitive to SO2, and a ground resolution of 25 km. The unique L1 vantage point provides continuous observations of the sunlit Earth disk, from sunrise to sunset, offering multiple daily observations of volcanic SO2 and ash clouds in the EPIC field of view. When coupled with complementary retrievals from polar-orbiting UV and IR sensors such as the Ozone Monitoring Instrument (OMI), the Ozone Mapping and Profiler Suite (OMPS), and the Atmospheric Infrared Sounder (AIRS), we demonstrate how the increased observation frequency afforded by DSCOVR/EPIC permits more timely volcanic eruption detection and novel analyses of the temporal evolution of volcanic clouds. Although EPIC has detected several mid- to high-latitude volcanic eruptions since launch, we focus on recent eruptions of Bogoslof volcano (Aleutian Islands, AK, USA). A series of EPIC exposures from May 28-29, 2017, uniquely captures the evolution of SO2 mass in a young Bogoslof eruption cloud, showing separation of SO2- and ice-rich regions of the cloud. We show how analyses of these sequences of EPIC SO2 data can elucidate poorly understood processes in transient eruption

A Woman Voice in an Epic: Tracing Gendered Motifs in Anne Vabarna's Peko

Directory of Open Access Journals (Sweden)

Andreas Kalkun

2008-12-01

Full Text Available In the article the gendered motifs found in Anne Vabarna’s Seto epic Peko are analysed. Besides the narrative telling of the life of the male hero, the motives regarding eating, refusing to eat or offering food, and the aspect of the female body or its control deserve to be noticed. These scenes do not communicate the main plot, they are often related to minor characters of the epic and slow down the narrative, but at the same time they clearly carry artistic purpose and meaning. I consider these motifs, present in the liminal parts of the epic, to be the dominant symbols of the epic where the author’s feminine world is being exposed. Observing these motifs of Peko in the context of Seto religious worldview, the life of Anne Vabarna and the social position of Seto women, the symbols become eloquent and informative.

The interview-administered 24 h dietary recall (24-HDR) EPIC-Soft® has a series of controls to guarantee the quality of dietary data across countries. These comprise all steps that are part of fieldwork preparation, data collection and data management; however, a complete characterisation of these quality controls is still lacking. The present paper describes in detail the quality controls applied in EPIC-Soft, which are, to a large extent, built on the basis of the EPIC-Soft error model and are present in three phases: (1) before, (2) during and (3) after the 24-HDR interviews. Quality controls for consistency and harmonisation are implemented before the interviews while preparing the seventy databases constituting an EPIC-Soft version (e.g. pre-defined and coded foods and recipes). During the interviews, EPIC-Soft uses a cognitive approach by helping the respondent to recall the dietary intake information in a stepwise manner and includes controls for consistency (e.g. probing questions) as well as for completeness of the collected data (e.g. system calculation for some unknown amounts). After the interviews, a series of controls can be applied by dietitians and data managers to further guarantee data quality. For example, the interview-specific 'note files' that were created to track any problems or missing information during the interviews can be checked to clarify the information initially provided. Overall, the quality controls employed in the EPIC-Soft methodology are not always perceivable, but prove to be of assistance for its overall standardisation and possibly for the accuracy of the collected data.

A study of some features of the ultra high vacuum systems for EPIC

International Nuclear Information System (INIS)

Elsey, R.J.; Bennett, J.R.J.; Dossett, A.J.

1977-01-01

This report covers the experimental work carried out towards the development of the ultra high vacuum for the proposed electron positron storage ring, EPIC. Experiments included outgassing tests on samples of materials and pump-down tests on full scale aluminium vessels. The effect of baking was investigated. The approval of the similar machine PETRA at Hamburg and the subsequent withdrawal of the EPIC proposal in October 1975 curtailed the vacuum work. The experiments reported here are therefore incomplete, but nevertheless proved useful in showing that there should have been no major problems with building the vacuum system for EPIC. (author)

Gonzalez-Lopez, David; Faerber, Gloria; Diab, Mahmoud; Amorim, Paulo; Zeynalov, Natig; Doenst, Torsten

2017-10-01

Current sizing strategies suggest valve selection based on annulus diameter despite supra-annular placement of biological prostheses potentially allowing placement of a larger size. We assessed the frequency of selecting a larger prosthesis if prosthesis size was selected using a replica (upsizing) and evaluated its impact on haemodynamics. We analysed all discharge echocardiograms between June 2012 and June 2014, where a replica sizer was used for isolated aortic valve replacement (Epic Supra: 266 patients, Trifecta: 49 patients). Upsizing was possible in 71% of the Epic Supra valves (by 1 size: 168, by 2 sizes: 20) and in 59% of the Trifectas (by 1 size: 26, by 2 sizes: 3). Patients for whom upsizing was possible had the lowest pressure gradients within their annulus size groups. The difference was significant in annulus diameters of 21-22 or 25-26 mm (Epic Supra) and 23-24 mm (Trifecta). Trifecta gradients were the lowest. However, the ability to upsize the Epic Supra by 2 sizes eliminated the differences between Epic Supra and Trifecta. Upsizing did not cause intraoperative complications. Using replica sizers for aortic prosthesis size selection allows the implantation of bigger prostheses than recommended in most cases and reduces postoperative gradients, specifically for Epic Supra. © The Author 2017.

Archiving a large fraction of the EPICS signals within the Jefferson Lab (JLAB) Accelerator control system is vital for postmortem and real-time analysis of the accelerator performance. This analysis is performed on a daily basis by scientists, operators, engineers, technicians, and software developers. Archiving poses unique challenges due to the magnitude of the control system. A MySQL Archiving system (Mya) was developed to scale to the needs of the control system; currently archiving 58,000 EPICS variables, updating at a rate of 11,000 events per second. In addition to the large collection rate, retrieval of the archived data must also be fast and robust. Archived data retrieval clients obtain data at a rate over 100,000 data points per second. Managing the data in a relational database provides a number of benefits. This paper describes an archiving solution that uses an open source database and standard off the shelf hardware to reach high performance archiving needs. Mya has been in production at Jefferson Lab since February of 2007.

This work presents a fast acquisition multipurpose controller, focussing on its EPICS integration and on its XML based configuration. This controller is based on a Lyrtech VHS-ADC board which encloses an FPGA, connected to a Host PC. This Host acts as local controller and implements an IOC integrating the device in an EPICS network. These tasks have been performed using Java as the main tool to program the PC to make the device fit the desired application. All the process includes the use of different technologies: JNA to handle C functions i.e. FPGA API, JavaIOC to integrate EPICS and XML w3c DOM classes to easily configure the particular application. In order to manage the functions, Java specific tools have been developed: Methods to manage the FPGA (read/write registers, acquire data,...), methods to create and use the EPICS server (put, get, monitor,...), mathematical methods to process the data (numeric format conversions,...) and methods to create/ initialize the application structure by means of an XML file (parse elements, build the DOM and the specific application structure). This XML file has some common nodes and tags for all the applications: FPGA registers specifications definition and EPICS variables. This means that the user only has to include a node for the specific application and use the mentioned tools. A main class is in charge of managing the FPGA and EPICS server according to this XML file. This multipurpose controller has been successfully used to implement a BPM and an LLRF application for the ESS-Bilbao (European Spallation Source) facility. (authors)

Epic and Romance in The Lord Of The Rings

Directory of Open Access Journals (Sweden)

Martin Simonson

2016-10-01

Full Text Available In the field of comparative literature The Lord of the Rings has been most frequently studied within the contexts of romance and epic. This approach, however, leaves out important generic aspects of the global picture, such as the narrative’s strong adherence to the novel genre and to mythic traditions beyond romance and epic narratives. If we choose one particular genre as the yardstick against which to measure the work’s success in narrative terms, we tend to end up with the conclusion that The Lord of the Rings does not quite make sense within the given limits of the genre in question. In Tolkien’s work there is a narrative and stylistic exploration of the different genres’ constraints in which the Western narrative traditions – myth, epic, romance, the novel, and their respective subgenres – interact in a previously unknown but still very much coherent world that, because of the particular cohesion required by such a chronotope, exhibits a clear contextualization of references to the previous traditions. As opposed to many contemporary literary expressions, the ensuing absence of irony and parody creates a generic dialogue, in which the various narrative traditions explore and interrogate each other’s limits without rendering the others absurdly incompatible, ridiculous or superfluous.

2012-01-01

Data storage is a primary issue in any research facility. In the EPICS middleware based accelerator community, Channel Archiver has been always considered the main reference. It works with Oracle and MySQL, probably the best well known relational databases. However, demanding requirements at minimum costs have fostered the development of a wide range of alternatives, like MDSPlus (Consorzio RFX), SciDB (BNL) or Hypertable (IFNF). This document launches a tool called HyperArchiver, which was firstly developed at IFNF (Italy) and eventually customised by ESS Bilbao (Spain). Based on a NoSQL database named Hypertable, it focuses on large data sets management with maximum scalability, reliability and performance. Besides the update and further customization made at ESS Bilbao, HyperArchiver is presented with a set of GUIs, in order to provide an easy use and integration with any general control system. A LabVIEW VI and two cross-platform PyQt GUIs for both Hypertable data retrieval and HyperArchiver control have been developed and successfully tested at ESS Bilbao. (author)

Sources of mineral phosphorus (P) fertilizers are non-renewable. Although the longevity of P mines and the risk of future P depletion are highly debated P scarcity may be detrimental to agriculture in various ways. Some of these impacts include increasing food insecurity and nitrogen (N) and P imbalances, serious fluctuations in the global fertilizer and crop market prices, and contribution in geopolitical conflicts. P-rich waste produced from livestock production activities (i.e. manure) are an alternative to mineral P fertilizer. The substitution of mineral fertilizer with manure (1) delays the depletion of phosphate rock stocks, (2) reduces the vulnerability of P fertilizer importing countries to sudden changes in the fertilizer market, (3) reduces the chances of geopolitical conflicts arising from P exploitation pressures, (4) avoids the need for environmental protection policies in livestock systems, (5) is an opportunity for the boosting of crop yields in low nutrient input agricultural systems, and (6) contributes to the inflow of not only P but also other essential nutrients to agricultural soils. The Environmental Policy Integrated Climate model (EPIC) is a widely used process-based, crop model integrating various environmental flows relevant to crop production as well as environmental quality assessments. We simulate crop yields using a powerful computer cluster infra-structure (known as EPIC-IIASA) in combination with spatially-explicit EPIC input data on climate, management, soils, and landscape. EPIC-IIASA contains over 131,000 simulation units and it has 5 arc-min resolution. In this work, we implement two process-based models of manure biogeochemistry into EPIC-IIASA, i.e. SurPhos (for P) and Manure DNDC (for N and carbon) and a fate model model describing nutrient outflows from fertilizer via runoff. For EGU, we will use EPIC-IIASA to quantify the potential of mineral P fertilizer substitution with manure. Specifically, we will estimate the relative

As controls needs at the Advanced Photon Source matured from an installation phase to an operational phase, the need to monitor the existing conventional facilities control system with the EPICS-based accelerator control system was realized. This existing conventional facilities control network is based on a proprietary system from Johnson Controls called Metasys. Initially read-only monitoring of the Metasys parameters will be provided; however, the ability for possible future expansion to full control is available. This paper describes a method of using commercially available hardware and existing EPICS software as a bridge between the Metasys and EPICS control systems

To describe the research methods for the development of a new open source, cross-platform tool which processes data from the European Prospective Investigation into Cancer and Nutrition Norfolk Food Frequency Questionnaire (EPIC-Norfolk FFQ). A further aim was to compare nutrient and food group values derived from the current tool (FETA, FFQ EPIC Tool for Analysis) with the previously validated but less accessible tool, CAFÉ (Compositional Analyses from Frequency Estimates). The effect of text matching on intake data was also investigated. Cross-sectional analysis of a prospective cohort study-EPIC-Norfolk. East England population (city of Norwich and its surrounding small towns and rural areas). Complete FFQ data from 11 250 men and 13 602 women (mean age 59 years; range 40-79 years). Nutrient and food group intakes derived from FETA and CAFÉ analyses of EPIC-Norfolk FFQ data. Nutrient outputs from FETA and CAFÉ were similar; mean (SD) energy intake from FETA was 9222 kJ (2633) in men, 8113 kJ (2296) in women, compared with CAFÉ intakes of 9175 kJ (2630) in men, 8091 kJ (2298) in women. The majority of differences resulted in one or less quintile change (98.7%). Only mean daily fruit and vegetable food group intakes were higher in women than in men (278 vs 212 and 284 vs 255 g, respectively). Quintile changes were evident for all nutrients, with the exception of alcohol, when text matching was not executed; however, only the cereals food group was affected. FETA produces similar nutrient and food group values to the previously validated CAFÉ but has the advantages of being open source, cross-platform and complete with a data-entry form directly compatible with the software. The tool will facilitate research using the EPIC-Norfolk FFQ, and can be customised for different study populations.

Jllumina - A comprehensive Java-based API for statistical Illumina Infinium HumanMethylation450 and Infinium MethylationEPIC BeadChip data processing

Directory of Open Access Journals (Sweden)

Almeida Diogo

2016-10-01

Full Text Available Measuring differential methylation of the DNA is the nowadays most common approach to linking epigenetic modifications to diseases (called epigenome-wide association studies, EWAS. For its low cost, its efficiency and easy handling, the Illumina HumanMethylation450 BeadChip and its successor, the Infinium MethylationEPIC BeadChip, is the by far most popular techniques for conduction EWAS in large patient cohorts. Despite the popularity of this chip technology, raw data processing and statistical analysis of the array data remains far from trivial and still lacks dedicated software libraries enabling high quality and statistically sound downstream analyses. As of yet, only R-based solutions are freely available for low-level processing of the Illumina chip data. However, the lack of alternative libraries poses a hurdle for the development of new bioinformatic tools, in particular when it comes to web services or applications where run time and memory consumption matter, or EWAS data analysis is an integrative part of a bigger framework or data analysis pipeline. We have therefore developed and implemented Jllumina, an open-source Java library for raw data manipulation of Illumina Infinium HumanMethylation450 and Infinium MethylationEPIC BeadChip data, supporting the developer with Java functions covering reading and preprocessing the raw data, down to statistical assessment, permutation tests, and identification of differentially methylated loci. Jllumina is fully parallelizable and publicly available at http://dimmer.compbio.sdu.dk/download.html

POPULARIZING EPIC NARRATIVE IN GEORGE R.R. MARTIN'S A GAME OF THRONES

2012-11-01

Full Text Available This research is intended to show the sustainability of epic in latest years of human history through the most phenomenal fantasy in American literature, A Game of Thrones. Along with the capability of human beings in thinking dearly and sensibly, it is commonsensical that people tend to free themselves from irrationality. The reality shows, however, that the existence of epic fantasy still has power in appealing audiences or readers. This is the case with A Game of Thrones written by George RR Martin who was given the award of One of The Most Influential People in 2011 by Time magazine. This qualitative march, using genre approach, finds out that in order to be compatible with today's society, an epic seen in A Game of Thrones, which is commonly known as a story centering on the legendary hero and his heroic deed in oral folk tradition, keeps its power as an epic fantasy narrative through certain archetypes and formulas. Through genre analysis using semiotic approach, the research brings about conclusions that the elements of high fantasy, elements built through rational representation, and a smart combination of convention and invention brings about its popularity. It is also concluded that there is a close relationship between the myth and the mode of people living even in the most modern context.

There is epidemiologic evidence that the consumption of fried, grilled or barbecued meat and fish that are well-done or browned may be associated with an increased cancer risk. These high-temperature cooking methods are thought to be surrogates for mutagens and carcinogens produced in meat and fish, eg heterocyclic amines or polycyclic hydrocarbons. Since data on food cooking methods are scarce, the aim of this study was to describe the variation in meat and fish cooking methods in different parts of Europe. Using a standardized 24 h recall from a sub-sample of the EPIC cohort (35 644 persons, 35-75 y old), mean daily intake of meat and fish prepared by different cooking methods and the relative contribution of the cooking methods to the overall cooking of meat and fish was calculated. Whereas frying was more often noted in northern Europe, roasting and stir frying were more often used in the south. Concerning high-temperature cooking methods, their frequency of application varies between 15% in the EPIC cohort of North-Italy and 49% in the cohort of The Netherlands. Average consumption of fried, grilled and barbecued meat and fish ranges from a low of 12 g/day in the centres in southern Spain to a high of 91 g/day in northern Spain. High variation in both the kind of meat/fish consumed as well as its cooking methods is observed within EPIC. In order to use this variation for the evaluation of the impact of cooking methods on cancer risk, a questionnaire on meat and fish cooking methods is being developed and could be applied in the whole EPIC cohort.

The EPIC-Heidelberg and the EPIC-Potsdam studies with about 53,000 study participants represent the German contribution to the EPIC (European Investigation into Cancer and Nutrition) cohort study. Within the EPIC study, standardized 24-hour dietary recalls were applied as a quantitative calibration method in order to estimate the amount of scaling bias introduced by the varying center-specific dietary assessment methods. This article presents intake of food items and food groups in the two German cohorts estimated by 24-hour quantitative dietary recalls. Recalls from 1,013 men and 1,078 women in Heidelberg and 1,032 men and 898 women in Potsdam were included in the analysis. The intake of recorded food items or recipe ingredients as well as fat used for cooking was summarized into 16 main food groups and a variety of different subgroups stratified by sex and weighted for the day of the week and age. In more than 90% of the recalls, consumption of dairy products, cereals and cereal products, bread, fat, and non-alcoholic beverages, particularly coffee/tea, was reported. Inter-cohort evaluations revealed that bread, potatoes, fruit and fat were consumed in higher amounts in the Potsdam cohort while the opposite was found for pasta/rice, non-alcoholic, and alcoholic beverages. It was concluded that the exposure variation was increased by having two instead of one EPIC study centers in Germany. Copyright 1999 S. Karger AG, Basel

Uncertainties in cloud phase and optical thickness retrievals from the Earth Polychromatic Imaging Camera (EPIC).

Science.gov (United States)

Meyer, Kerry; Yang, Yuekui; Platnick, Steven

2016-01-01

This paper presents an investigation of the expected uncertainties of a single channel cloud optical thickness (COT) retrieval technique, as well as a simple cloud temperature threshold based thermodynamic phase approach, in support of the Deep Space Climate Observatory (DSCOVR) mission. DSCOVR cloud products will be derived from Earth Polychromatic Imaging Camera (EPIC) observations in the ultraviolet and visible spectra. Since EPIC is not equipped with a spectral channel in the shortwave or mid-wave infrared that is sensitive to cloud effective radius (CER), COT will be inferred from a single visible channel with the assumption of appropriate CER values for liquid and ice phase clouds. One month of Aqua MODIS daytime granules from April 2005 is selected for investigating cloud phase sensitivity, and a subset of these granules that has similar EPIC sun-view geometry is selected for investigating COT uncertainties. EPIC COT retrievals are simulated with the same algorithm as the operational MODIS cloud products (MOD06), except using fixed phase-dependent CER values. Uncertainty estimates are derived by comparing the single channel COT retrievals with the baseline bi-spectral MODIS retrievals. Results show that a single channel COT retrieval is feasible for EPIC. For ice clouds, single channel retrieval errors are minimal (< 2%) due to the particle size insensitivity of the assumed ice crystal (i.e., severely roughened aggregate of hexagonal columns) scattering properties at visible wavelengths, while for liquid clouds the error is mostly limited to within 10%, although for thin clouds (COT < 2) the error can be higher. Potential uncertainties in EPIC cloud masking and cloud temperature retrievals are not considered in this study.

A versatile trigger and synchronization module with IEEE1588 capabilities and EPICS support

Event timing and synchronization are two key aspects to improve in the implementation of distributed data acquisition (dDAQ) systems such as the ones used in fusion experiments. It is also of great importance the integration of dDAQ in control and measurement networks. This paper analyzes the applicability of the IEEE1588 and EPICS standards to solve these problems, and presents a hardware module implementation based in both of them that allow adding these functionalities to any DAQ. The IEEE1588 standard facilitates the integration of event timing and synchronization mechanisms in distributed data acquisition systems based on IEEE 803.3 (Ethernet). An optimal implementation of such system requires the use of network interface devices which include specific hardware resources devoted to the IEE1588 functionalities. Unfortunately, this is not the approach followed in most of the large number of applications available nowadays. Therefore, most solutions are based in software and use standard hardware network interfaces. This paper presents the development of a hardware module (GI2E) with IEEE1588 capabilities which includes USB, RS232, RS485 and CAN interfaces. This permits to integrate any DAQ element that uses these interfaces in dDAQ systems in an efficient and simple way. The module has been developed with Motorola's Coldfire MCF5234 processor and National Semiconductors's PHY DP83640T, providing it with the possibility to implement the PTP protocol of IEEE1588 by hardware, and therefore increasing its performance over other implementations based in software. To facilitate the integration of the dDAQ system in control and measurement networks the module includes a basic Input/Output Controller (IOC) functionality of the Experimental Physics and Industrial Control System (EPICS) architecture. The paper discusses the implementation details of this module and presents its applications in advanced dDAQ applications in the fusion community.

The paper describes the integration of Experimental Physics and Industrial Control System (EPICS) Channel Access (CA) protocol and Microsoft ActiveX technology towards developing a generalize operator interface (OPI) building facility for Windows platform. EPICS is used as the development architecture of the control system in Superconducting Cyclotron (SCC). Considering the operators' familiarity and compatibility with third party software, it was decided to use MS-Windows platform at operator interface level in SCC during commission. Microsoft Visual Basic (VB) is used on trial basis as OPI building platform to incorporate user specific features e.g. file system access for data storage and analysis, user authentication at OPI level etc. A set of EPICS Channel Access embedded ActiveX components is developed to ease the programming complexity and reduce developmental time of the OPI for Windows platform. OPIs, developed using these components and containing hundreds of process parameters, are being used reliably over a considerable period of time. (author)

The Spallation Neutron Source (SNS) accelerator systems will deliver a 1.0 GeV, 1.4 MW proton beam to a liquid mercury target for neutron scattering research. The accelerator complex consists of a 1 GeV linear accelerator, an accumulator ring and associated transport lines. The SNS diagnostics platform is PC-based and will run Windows for its OS and LabVIEW as its programming language. Data acquisition hardware will be based on PCI cards. There will be about 300 rack-mounted computers. The Channel Access (CA) protocol of the Experimental Physics and Industrial Control System (EPICS) is the SNS control system communication standard. This paper describes the approaches, implementation, and features of LabVIEW library to CA for Windows, Linux, and Mac OS X. We also discuss how the library implements the asynchronous CA monitor routine using LabVIEW's occurrence mechanism instead of a callback function (which is not available in LabVIEW). The library is used to acquire accelerator data and applications have been ...

Full Text Available Web applications vulnerabilities allow attackers to perform malicious actions that range from gaining unauthorized account access to obtaining sensitive data. The number of reported web application vulnerabilities in last decade is increasing dramatically. The most of vulnerabilities result from improper input validation and sanitization. The most important of these vulnerabilities based on improper input validation and sanitization are: SQL injection (SQLI, Cross-Site Scripting (XSS and Buffer Overflow (BOF. In order to address these vulnerabilities we designed and developed the WAPTT (Web Application Penetration Testing Tool tool - web application penetration testing tool. Unlike other web application penetration testing tools, this tool is modular, and can be easily extended by end-user. In order to improve efficiency of SQLI vulnerability detection, WAPTT uses an efficient algorithm for page similarity detection. The proposed tool showed promising results as compared to six well-known web application scanners in detecting various web application vulnerabilities.

Proton Engineering Frontier Project (PEFP) has developed a 20MeV proton accelerator, and established a distributed control system based on EPICS for sub-system components such as vacuum unit, beam diagnostics, and power supply system. The control system includes a real-time monitoring and alarm functions. From the aspect of a efficient maintenance of a control system and a additional extension of subsystems, EPICS software framework was adopted. In addition, a control system should be capable of providing an easy access for users and a real-time monitoring on a user screen. Therefore, we have implemented a new web-based monitoring server with several libraries. By adding DB module, the new IOC web monitoring system makes it possible to monitor the system through the web. By integrating EPICS Channel Access (CA) and Database libraries into a Database module, the web-based monitoring system makes it possible to monitor the sub-system status through user's internet browser. In this study, we developed a web based monitoring system by using EPICS IOC (Input Output Controller) with IBM server

Elpasolites are a promising new family of inorganic scintillators that can detect both gamma rays and neutrons within a single detector volume, reducing the instrument size, weight, and power (SWaP), all of which are critical for planetary science missions. The ability to distinguish between neutron and gamma events is done through pulse shape discrimination (PSD). The Elpasolite Planetary Ice and Composition Spectrometer (EPICS) utilizes elpasolites in a next-generation, highly capable, low-SWaP gamma-ray and neutron spectrometer. We present simulated capabilities of EPICS sensitivities to neutron and gamma-rays, and demonstrate how EPICS can constrain the origin of Phobos between the following three main hypotheses: 1) accretion after a giant impact with Mars, 2) co-accretion with Mars, and 3) capture of an external body. The MCNP6 code was used to calculate the neutron and gamma-ray flux that escape the surface of Phobos, and GEANT4 to model the response of the EPICS instrument on orbit around Phobos.

The Elpasolite Planetary Ice and Composition Spectrometer (EPICS) is an innovative, low-resource gamma-ray and neutron spectrometer for planetary science missions, enabled by new scintillator and photodetector technologies. Neutrons and gamma rays are produced by cosmic ray interactions with planetary bodies and their subsequent interactions with the near-surface materials produce distinctive energy spectra. Measuring these spectra reveals details of the planetary near-surface composition that are not accessible through any other phenomenology. EPICS will be the first planetary science instrument to fully integrate the neutron and gamma-ray spectrometers. This integration is enabled by the elpasolite family of scintillators that offer gamma-ray spectroscopy energy resolutions as good as 3% FWHM at 662 keV, thermal neutron sensitivity, and the ability to distinguish gamma-ray and neutron signals via pulse shape differences. This new detection technology will significantly reduce size, weight, and power (SWaP) while providing similar neutron performance and improved gamma energy resolution compared to previous scintillator instruments, and the ability to monitor the cosmic-ray source term. EPICS will detect scintillation light with silicon photomultipliers rather than traditional photomultiplier tubes, offering dramatic additional SWaP reduction. EPICS is under development with Los Alamos National Laboratory internal research and development funding. Here we report on the EPICS design, provide an update on the current status of the EPICS development, and discuss the expected sensitivity and performance of EPICS in several potential missions to airless bodies.

Full Text Available Se presenta el marco teórico, la lógica de elaboración y primeros datos de validación de un cuestionario de sabiduría epicúrea (EPI-1 que ha sido cumplimentado por dos muestras de 473 y 266 adultos, con un predominio de mujeres. Además, se han cumplimentado el cuestionario NEO-PI-R de Costa y McCrae de los cinco grandes y dos escalas conectadas teóricamente con concepciones de sabiduría: una de prudencia y otra de intolerancia a la ambigüedad. Los resultados sugieren que, aunque sin una consistencia alta, se pueden rastrear en nuestros días los elementos básicos de la sabiduría epicúrea que se mezclan con otros de corte más funcional. Las relaciones con los cinco grandes así como con prudencia interpersonal e intolerancia de la ambigüedad demuestran que la sabiduría epicúrea no puede identificarse con ninguna de estas dimensiones, aunque guarda relaciones tenues con neuroticismo, apertura a la experiencia e intolerancia de la ambigüedad; asimismo se presenta como independiente de “prudencia” operacionalizada mediante refranes, que representa más bien estrategias de “supervivencia interpersonal”. Los resultados alcanzados se discuten dentro de un modelo de sabiduría alternativo al del grupo de Baltes en Berlín.

A Client/Server Architecture for Supporting Science Data Using EPICS Version 4

Energy Technology Data Exchange (ETDEWEB)

Dalesio, Leo [EPIC Consulting, Jacksonville, FL (United States)

The Phase 1 grant that serves as a precursor to this proposal, prototyped complex storage techniques for high speed structured data that is being produced in accelerator diagnostics and beam line experiments. It demonstrates the technologies that can be used to archive and retrieve complex data structures and provide the performance required by our new accelerators, instrumentations, and detectors. Phase 2 is proposed to develop a high-performance platform for data acquisition and analysis to provide physicists and operators a better understanding of the beam dynamics. This proposal includes developing a platform for reading 109 MHz data at 10 KHz rates through a multicore front end processor, archiving the data to an archive repository that is then indexed for fast retrieval. The data is then retrieved from this data archive, integrated with the scalar data, to provide data sets to client applications for analysis, use in feedback, and to aid in identifying problem with the instrumentation, plant, beam steering, or model. This development is built on EPICS version 4 , which is being successfully deployed to implement physics applications. Through prior SBIR grants, EPICS version 4 has a solid communication protocol for middle layer services (PVAccess), structured data representation and methods for efficient transportation and access (PVData), an operational hierarchical record environment (JAVA IOC), and prototypes for standard structured data (Normative Types). This work was further developed through project funding to successfully deploy the first service based physics application environment with demonstrated services that provide arbitrary object views, save sets, model, lattice, and unit conversion. Thin client physics applications have been developed in Python that implement quad centering, orbit display, bump control, and slow orbit feedback. This service based architecture has provided a very modular and robust environment that enables commissioning teams

Uncertainties in cloud phase and optical thickness retrievals from the Earth Polychromatic Imaging Camera (EPIC)

2018-01-01

This paper presents an investigation of the expected uncertainties of a single channel cloud optical thickness (COT) retrieval technique, as well as a simple cloud temperature threshold based thermodynamic phase approach, in support of the Deep Space Climate Observatory (DSCOVR) mission. DSCOVR cloud products will be derived from Earth Polychromatic Imaging Camera (EPIC) observations in the ultraviolet and visible spectra. Since EPIC is not equipped with a spectral channel in the shortwave or mid-wave infrared that is sensitive to cloud effective radius (CER), COT will be inferred from a single visible channel with the assumption of appropriate CER values for liquid and ice phase clouds. One month of Aqua MODIS daytime granules from April 2005 is selected for investigating cloud phase sensitivity, and a subset of these granules that has similar EPIC sun-view geometry is selected for investigating COT uncertainties. EPIC COT retrievals are simulated with the same algorithm as the operational MODIS cloud products (MOD06), except using fixed phase-dependent CER values. Uncertainty estimates are derived by comparing the single channel COT retrievals with the baseline bi-spectral MODIS retrievals. Results show that a single channel COT retrieval is feasible for EPIC. For ice clouds, single channel retrieval errors are minimal (clouds the error is mostly limited to within 10%, although for thin clouds (COT cloud masking and cloud temperature retrievals are not considered in this study.

No official German translation exists for the 50-item Expanded Prostate Cancer Index Composite (EPIC), and no minimal important difference (MID) has been established yet. The aim of the study was to translate and validate a German version of the EPIC with cultural adaptation to the different German speaking countries and to establish the MID. We translated and culturally adapted the EPIC into German. For validation, we included a consecutive subsample of 92 patients with localized prostate cancer undergoing radical prostatectomy who participated the Prostate Cancer Outcomes Cohort. Baseline and follow-up assessments took place before and six weeks after prostatectomy in 2010 and 2011. We assessed the EPIC, EORTC QLQ-PR25, Feeling Thermometer, SF-36 and a global rating of health state change variable. We calculated the internal consistency, test-retest reliability, construct validity, responsiveness and MID. For most EPIC domains and subscales, our a priori defined criteria for reliability were fulfilled (construct reliability: Cronbach's alpha 0.7-0.9; test-retest reliability: intraclass-correlation coefficient ≥ 0.7). Cross-sectional and longitudinal correlations between EPIC and EORTC QLQ-PR25 domains ranged from 0.14-0.79, and 0.06-0.5 and 0.08-0.72 for Feeling Thermometer and SF-36, respectively. We established MID values of 10, 4, 12, and 6 for the urinary, bowel, sexual and hormonal domain. The German version of the EPIC is reliable, responsive and valid to measure HRQL in prostate cancer patients and is now available in German language. With the suggested MID we provide interpretation to what extent changes in HRQL are clinically relevant for patients. Hence, study results are of interest beyond German speaking countries.

This article presents intakes of nutrients in the EPIC-Heidelberg and the EPIC-Potsdam (European Investigation into Cancer and Nutrition) studies. Estimates are based on standardized 24-hour dietary recalls. Recalls from 1,013 men and 1,078 women in Heidelberg and from 1,032 men and 898 women in Potsdam were included in the analysis. The estimated nutrient intake was based on the German Food Code and Nutrient Data Base version II.3. Analyses were carried out stratified by sex and weighted for the day of the week and age. Men in Potsdam reported significantly higher intakes of energy (mean Potsdam = 10,718 kJ, mean Heidelberg = 10,387 kJ) and higher intakes of vitamins and minerals as compared with men in Heidelberg. However, Heidelberg men consumed more alcohol, alpha-tocopherol, phosphorus, calcium, and magnesium. Potsdam women reported lower energy (mean Potsdam = 7,537 kJ, mean Heidelberg = 7,855 kJ), alcohol, and cholesterol intakes as compared with Heidelberg women. Vitamin and mineral intakes were lower too, except for retinol and ascorbic acid. The intakes of energy and most nutrients observed in the Potsdam and Heidelberg study populations were within the range reported from other German studies. The observed differences between both study populations indicate different dietary patterns, increasing the exposure variation in the EPIC study. Copyright 2001 S. Karger AG, Basel

Fast radiative transfer models for retrieval of cloud properties in the back-scattering region: application to DSCOVR-EPIC sensor

Molina Garcia, Victor; Sasi, Sruthy; Efremenko, Dmitry; Doicu, Adrian; Loyola, Diego

In this work, the requirements for the retrieval of cloud properties in the back-scattering region are described, and their application to the measurements taken by the Earth Polychromatic Imaging Camera (EPIC) on board the Deep Space Climate Observatory (DSCOVR) is shown. Various radiative transfer models and their linearizations are implemented, and their advantages and issues are analyzed. As radiative transfer calculations in the back-scattering region are computationally time-consuming, several acceleration techniques are also studied. The radiative transfer models analyzed include the exact Discrete Ordinate method with Matrix Exponential (DOME), the Matrix Operator method with Matrix Exponential (MOME), and the approximate asymptotic and equivalent Lambertian cloud models. To reduce the computational cost of the line-by-line (LBL) calculations, the k-distribution method, the Principal Component Analysis (PCA) and a combination of the k-distribution method plus PCA are used. The linearized radiative transfer models for retrieval of cloud properties include the Linearized Discrete Ordinate method with Matrix Exponential (LDOME), the Linearized Matrix Operator method with Matrix Exponential (LMOME) and the Forward-Adjoint Discrete Ordinate method with Matrix Exponential (FADOME). These models were applied to the EPIC oxygen-A band absorption channel at 764 nm. It is shown that the approximate asymptotic and equivalent Lambertian cloud models give inaccurate results, so an offline processor for the retrieval of cloud properties in the back-scattering region requires the use of exact models such as DOME and MOME, which behave similarly. The combination of the k-distribution method plus PCA presents similar accuracy to the LBL calculations, but it is up to 360 times faster, and the relative errors for the computed radiances are less than 1.5% compared to the results when the exact phase function is used. Finally, the linearized models studied show similar behavior

Analyzing multiple single nucleotide polymorphisms (SNPs) is a promising approach to finding genetic effects beyond single-locus associations. We proposed the use of multilocus stepwise regression (MSR) to screen for allele combinations as a method to model joint effects, and compared the results with the often used genetic risk score (GRS), conventional stepwise selection, and the shrinkage method LASSO. In contrast to MSR, the GRS, conventional stepwise selection, and LASSO model each genotype by the risk allele doses. We reanalyzed 20 unlinked SNPs related to type 2 diabetes (T2D) in the EPIC-Potsdam case-cohort study (760 cases, 2193 noncases). No SNP-SNP interactions and no nonlinear effects were found. Two SNP combinations selected by MSR (Nagelkerke's R² = 0.050 and 0.048) included eight SNPs with mean allele combination frequency of 2%. GRS and stepwise selection selected nearly the same SNP combinations consisting of 12 and 13 SNPs (Nagelkerke's R² ranged from 0.020 to 0.029). LASSO showed similar results. The MSR method showed the best model fit measured by Nagelkerke's R² suggesting that further improvement may render this method a useful tool in genetic research. However, our comparison suggests that the GRS is a simple way to model genetic effects since it does not consider linkage, SNP-SNP interactions, and no non-linear effects. © 2015 John Wiley & Sons Ltd/University College London.

Indigenous women in Spanish American Historic Epic Poetry

Directory of Open Access Journals (Sweden)

Lise Segas

2016-05-01

Full Text Available Epic poetry has always been considered a masculine genre. The eruption of a group identity, masculine, white, aristocratic and christian, is the result of the representation and the exclusion of the Other, fictitious and singular, but in fact composed of a variety of ethnic groups, origins, sex, genders, religions and different degrees between fiction and historicity. Indeed, in the historical epic poetry which narrated the Conquest, except for the conquistadors listed at length and the indigenous kings and caciques, only few characters are distinguished by a historical individualisation. The Other, Amerindian and female, makes a shy entrance into history, into singularity, into the (historical and christian truth. It is the case of interpreters: Malinche and India Catalina, only historical native women that appear as part of the narrative plot as well as in the conquest enterprise in the poems of Lasso de la Vega (Cortés valeroso y Mexicana, Mexicana, of Juan de Castellanos (Elegías de varones ilustres de Indias and of Saavedra Guzmán (El peregrino indiano.

Cryogenic Plant of Variable Energy Cyclotron Centre consists of two Helium refrigerators (250W and 415W at the rate 4.5K), valve box with sub-cooler and associated sub systems like pure gas storage, helium purifier and impure gas recovery etc. The system also consists of 3.1K liters of liquid Nitrogen (LN 2 ) storage and delivery system. Many of the systems are procured from different suppliers and some are also developed in house. Due to the variety of systems and suppliers the control philosophy, communication protocols and component is also different. So the Supervisory control and data acquisition (SCADA) module has to be such that it can take care of the variance and bring everything into a common control platform. To solve this purpose EPICS (Experimental Physics and Industrial Control System) architecture has been adopted. EPICS is having the advantage of being open source, flexible and unlimited as compared to the commercial SCADA packages. (author)

Juvencus and the biblical epic: specificity and literary criticism

Full Text Available Latin Christian poetry has emerged in  Constantine Era and flourished between 400 and 800. It has a fundamental role in the development of literary theory and critical discourse, because, except for Prudencio, the rest of the poets of this first period has chosen by the adaptation of the classical canon to Christian themes. The Christian epic is therefore one of the first genres and begins as biblical epic. The first major work of this type is the Gospel Harmony from the Spanish poet Juvencus, until 330. This work begins a long series of biblical poetry, Latin at first, but after this there is its continuation in the vernaculars, like Caedmon, Cynewulf, The Heliand, The Passion by Clermont till Ojeda, Milton and Klopstock.The dedication to the established authority , the subordination of the art´s purpose for the salvation of the soul as well as the desire to legitimize poetry with Christian arguments remain as fundamental premises in the construction of gender. When the modern epic apear, its compromise with new theological Aporia will not lose those extraliterary requirements from provenance.Keywords: Latin Christian poetry; Constantine Era; Virgil.

Full Text Available In the European Investigation into Cancer and Nutrition study (EPIC, physical activity (PA has been indexed as a cross-tabulation between PA at work and recreational activity. As the proportion of non-working participants increases, other categorization strategies are needed. Therefore, our aim was to develop a valid PA index for this population, which will also be able to express PA continuously. In the German EPIC centers Potsdam and Heidelberg, a clustered sample of 3,766 participants was re-invited to the study center. 1,615 participants agreed to participate and 1,344 participants were finally included in this study. PA was measured by questionnaires on defined activities and a 7-day combined heart rate and acceleration sensor. In a training sample of 433 participants, the Improved Physical Activity Index (IPAI was developed. Its performance was evaluated in a validation sample of 911 participants and compared with the Cambridge Index and the Total PA Index. The IPAI consists of items covering five areas including PA at work, sport, cycling, television viewing, and computer use. The correlations of the IPAI with accelerometer counts in the training and validation sample ranged r = 0.40-0.43 and with physical activity energy expenditure (PAEE r = 0.33-0.40 and were higher than for the Cambridge Index and the Total PA Index previously applied in EPIC. In non-working participants the IPAI showed higher correlations than the Cambridge Index and the Total PA Index, with r = 0.34 for accelerometer counts and r = 0.29 for PAEE. In conclusion, we developed a valid physical activity index which is able to express PA continuously as well as to categorize participants according to their PA level. In populations with increasing rates of non-working people the performance of the IPAI is better than the established indices used in EPIC.

THE PLOT OF HUSBAND’S RETURN TO HIS WIFE’S WEDDING IN "THE ODYSSEY" BY HOMER AND IN THE SLAVIC AND RUSSIAN EPIC

Full Text Available The article analyzes the plot of husband’s return to his wife’s wedding embodied both in the millenary Ancient epic literature represented by the "Odyssey" of Homer, and in the Russian and Slavic epic. The study of Homer’s epic heritage, conducted over the years, includes a huge number of works of scientists around the world. Comparative-historical, comparative-genetic and comparative-typological studies found a link between oral folk tradition and epic poetry written by an author. The current international science is developing the hypothesis that professionally individual Homeric poems, which are at least 850 years old, were created in the ancient, oral poetry improvisation in a precise format of hexameter. The study of the Russian epic has less history, but the researches in this field have revealed the presence of Late Antiquity elements in the Slavic environment. These elements along with paganism and Christianity became the source of the people’s spiritual culture. The plot "the return of her husband", which is analyzed in the article, is widely-spread in folklore of many nations, and appeared rudimentarily in "The Odyssey". The western and eastern variants of this theme are diverse in genre structure and stylistic features. In Russian tradition the plot is presented in a large thematic variety "Dobrynya and Alyosha", which evolves into the epic genre due to contamination, small inserts in the epic genre. As a result, the great volume brings together the olden time and the ancient epic, creating intermediate forms comparable with the author’s imitations.

Controlling the beam spot size and shape in a diffraction experiment determines the probed sample volume. The HIPPO - High-Pressure-Preferred Orientation– neutron time-offlight diffractometer is located at the Lujan Neutron Scattering Center in Los Alamos National Laboratories. HIPPO characterizes microstructural parameters, such as phase composition, strains, grain size, or texture, of bulk (cm-sized) samples. In the current setup, the beam spot has a 10 mm diameter. Using a collimator, consisting of two pairs of neutron absorbing boron-nitride slabs, horizontal and vertical dimensions of a rectangular beam spot can be defined. Using the HIPPO robotic sample changer for sample motion, the collimator would enable scanning of e.g. cylindrical samples along the cylinder axis by probing slices of such samples. The project presented here describes implementation of such a collimator, in particular the motion control software. We utilized the EPICS (Experimental Physics Interface and Control System) software interface to integrate the collimator control into the HIPPO instrument control system. Using EPICS, commands are sent to commercial stepper motors that move the beam windows.

Modbus is a client/server communication model. In our applications, the embedded Ethernet device XPort is designed as the server and a SoftIOC running EPICS Modbus is the client. The SoftIOC builds a Modbus request from parameter contained in a demand that is sent by the EPICS application to the Modbus Client interface. On reception of the Modbus request, the Modbus server activates a local action to read, write, or achieve some other action. So, the main Modbus server functions are to wait for a Modbus request on 502 TCP port, treat this request, and then build a Modbus response.

Full Text Available Teesid: Artikkel keskendub eepose „Kalevipoeg“ käsitlusele võrdleva kirjandusteaduse vaatepunktist. „Kalevipoja“ uurimine ilukirjandusliku teosena muutis paradigmaatiliselt rahvuseepose senist tõlgendust ja seda tänu Jüri Talveti käsitlustele „Kalevipojast“ kui suurest Euroopa eeposest, silmapaistavast maailmakirjanduse kunsteeposte seas. Eepose teksti ja poeetika kirjandusteaduslik uurimine on selgitanud, kuidas eepose tekst on üles ehitatud sisemistele, intratekstuaalsetele seostele, mis korduvad gradatsiooniliselt ja toetuvad teatud kindlatele tekstuaalsetele sõlmpunktidele, näiteks „Saarepiiga“, „uni“ jpt. Enam kui autentsed allikad, on „Kalevipoja“ kui kirjandusliku teksti puhul oluline eepose toimimine pidevalt uusi tekste ärgitava tüvitekstina. Eepose analüüs näitab, kuidas selliste seoste alusel tekivad uued kultuurilised ühikud, kauneid näiteid selliste motiivikordustele rajatud seosteahelate kohta leidub ka Jüri Talveti luules.   The article focuses on the treatment of the epic The Kalevipoeg from the viewpoint of comparative literature. This approach is a continuation of the study of literary relations of the epic which, on the one hand is opposite to, but on the other hand continues the present folkloristic approach to The Kalevipoeg as a folklore-based epic, which is based on the comparative-historical method of studying folklore. F. R. Kreutzwald’s role in creating the national epic was enormous; the epic can be conceived as a fictional and intentional piece, emphasising the role of its author. Although different genres of genuine folklore can be recognised in the epic, works of fiction of European and world classics have also been used in its construction, and the text of the epic has itself become an intertextual foundation for new works of fiction. The paradigm of discussing the epic changed due to Jüri Talvet’s groundbreaking treatment of The Kalevipoeg as a great European epic and

Aedes aegypti, Aedes notoscriptus, and Aedes albopictus are important vectors of many arboviruses implicated in human disease such as dengue fever. Genetic markers applied across vector species can provide important information on population structure, gene flow, insecticide resistance, and taxonomy, however, robust microsatellite markers have proven difficult to develop in these species and mosquitoes generally. Here we consider the utility and transferability of 15 Ribosome protein (Rp) Exon-Primed Intron-Crossing (EPIC) markers for population genetic studies in these 3 Aedes species. Rp EPIC markers designed for Ae. aegypti also successfully amplified populations of the sister species, Ae. albopictus, as well as the distantly related species, Ae. notoscriptus. High SNP and good indel diversity in sequenced alleles plus support for amplification of the same regions across populations and species were additional benefits of these markers. These findings point to the general value of EPIC markers in mosquito population studies. © 2014 Institute of Zoology, Chinese Academy of Sciences.

EPIC Calibration/Validation Experiment Field Campaign Report

Koch, Steven E [National Severe Storm Laboratory/NOAA; Chilson, Phillip [University of Oklahoma; Argrow, Brian [University of Colorado

2017-03-15

A field exercise involving several different kinds of Unmanned Aerial Systems (UAS) and supporting instrumentation systems provided by DOE/ARM and NOAA/NSSL was conducted at the ARM SGP site in Lamont, Oklahoma on 29-30 October 2016. This campaign was part of a larger National Oceanic and Atmospheric Administration (NOAA) UAS Program Office program awarded to the National Severe Storms Laboratory (NSSL). named Environmental Profiling and Initiation of Convection (EPIC). The EPIC Field Campaign (Test and Calibration/Validation) proposed to ARM was a test or “dry-run” for a follow-up campaign to be requested for spring/summer 2017. The EPIC project addresses NOAA’s objective to “evaluate options for UAS profiling of the lower atmosphere with applications for severe weather.” The project goal is to demonstrate that fixed-wing and rotary-wing small UAS have the combined potential to provide a unique observing system capable of providing detailed profiles of temperature, moisture, and winds within the atmospheric boundary layer (ABL) to help determine the potential for severe weather development. Specific project objectives are: 1) to develop small UAS capable of acquiring needed wind and thermodynamic profiles and transects of the ABL using one fixed-wing UAS operating in tandem with two different fixed rotary-wing UAS pairs; 2) adapt and test miniaturized, high-precision, and fast-response atmospheric sensors with high accuracy in strong winds characteristic of the pre-convective ABL in Oklahoma; 3) conduct targeted short-duration experiments at the ARM Southern Great Plains site in northern Oklahoma concurrently with a second site to be chosen in “real-time” from the Oklahoma Mesonet in coordination with the (National Weather Service (NWS)-Norman Forecast Office; and 4) gain valuable experience in pursuit of NOAA’s goals for determining the value of airborne, mobile observing systems for monitoring rapidly evolving high-impact severe weather

Full Text Available Presence of common qualities in texts shows that the flow of events, heroes, traditions and customs, the course lead upon the events, attitudes and behaviors are very similar and repeated nearly in all texts. The only thing that changes is the hero that the story is arrayed in the name of. Every text more or less repeats itself. At the end, it is found that repetition movement is handled and executed in Dede Korkut epics like a system; repetitions are very strong and play a great role in constitution of both text and macro text. In addition, repetitions serve greatly in view of Dede Korkut epics as a whole. Repetitions that we see in the subject, time, place, character names, tradition, order of event flow etc. give wholeness to the epics as content. On the other hand, construct of every text in a similar style appears as an indication that integrity has not been achieved in epics in terms of composition.

DeLay, Tom; Smith, Brett H.; Ely, Kevin; MacArthur, Doug

1998-01-01

Tooling technology applications for composite structures fabrication have been expanded at MSFC's Productivity Enhancement Complex (PEC). Engineers from NASA/MSFC and Lockheed Martin Corporation have developed a tooling foam for use in composite materials processing and manufacturing that exhibits superior thermal and mechanical properties in comparison with other tooling foam materials. This tooling foam is also compatible with most preimpregnated composite resins such as epoxy, bismaleimide, phenolic and their associated cure cycles. MARCORE tooling foam has excellent processability for applications requiring either integral or removable tooling. It can also be tailored to meet the requirements for composite processing of parts with unlimited cross sectional area. A shelf life of at least six months is easily maintained when components are stored between 50F - 70F. The MARCORE tooling foam system is a two component urethane-modified polyisocyanurate, high density rigid foam with zero ozone depletion potential. This readily machineable, lightweight tooling foam is ideal for composite structures fabrication and is dimensionally stable at temperatures up to 350F and pressures of 100 psi.

The Experimental Projectile Impact Chamber (EPIC) consists of a 20.5mm caliber, compressed gas gun and a 7m wide test bed. It is possible to vary the projectile size and density, the velocity up to about 5001n/"s, the impact angle. and the target composition. The EPIC is especially designed for the analysis of impacts into unconsolidated and liquid targets. i.e. allowing the use of gravity scaling. The general objective with the EPIC is to analyze the cratering and modification processes at wet-target (e.g. marinle) impacts. We have carried out 14 shots into dry sand targets with two projectile compositions (light and weak; heavy and strong), at two impact angles. at three impact velocities, and in both quarter-space and half- space geometries. We recorded the impacts with a high-speed camera and compared the results with numerical simulations using iSALE. The evaluation demonstrated that there are noticeable differences between the results from the two projectile types, but that the crater dimensions are consistent with scaling laws based on other impact experiments [1]. This proves the usefulness of the EPIC in the analysis of natural impacts.

Molecular genetic analysis of cereal β-amylase genes using exon-primed intron-crossing (EPIC PCR

Directory of Open Access Journals (Sweden)

Stratula Olga

2014-01-01

Full Text Available The proteins encoded by cereal β-amylase genes Bamy1 and Bamy2 genes play an important role in seedling germination and in the brewing process. Here, we use exon-primed intron-crossing (EPIC to analyse Bamy1 and Bamy2 genetic diversity among 38 accessions belonging to six Poaceae tribes. DNA sequence alignment of multiple Poaceae species β-amylase sequences allowed design of EPIC primers that simultaneously amplify Bamy1 and Bamy2 in all the cereal species investigated. The genetic variation observed in the samples investigated is analysed and discussed, and illustrates the effectiveness of this approach for intra- and interspecific analysis in plant species.

Spectral re-distribution and surface loss effects in Swift XRT (XMM-Newton EPIC) MOS CCDs

CERN Document Server

Short, A D; Turner, M J L

2002-01-01

In the course of testing and selecting the EPIC MOS CCDs for the XMM-Newton observatory, the developed a Monte-Carlo model of the CCD response. Among other things, this model was used to investigate surface loss effects evident at low energies. By fitting laboratory data, these losses were characterised as a simple function of X-ray interaction depth and this result enabled the spectral re-distribution itself to be modelled as a simple analytical function. Subsequently, this analytical function has been used to generate the response matrix for the EPIC MOS instruments and will now be employed to model the spectral re-distribution for the Swift XRT CCD.

In large scale distributed control system, there are lots of common service composed an environment for the entire control system, such as the server system for the common software base library, application server, archive server and so on. This paper gives a description of a virtualization realization for control system environment including the virtualization for server, storage, network system and application for the control system. With a virtualization instance of the EPICS based control system environment that was built by the VMware vSphere v4, we tested the whole functionality of this virtualization environment in the SSRF control system, including the common server of the NFS, NIS, NTP, Boot and EPICS base and extension library tools, we also have applied virtualization to application servers such as the Archive, Alarm, EPICS gateway and all of the network based IOC. Specially, we test the high availability and VMotion for EPICS asynchronous IOC successful under the different VLAN configuration of the current SSRF control system network. (authors)

The evolution of Jefferson Lab's control system

K. S. White; M. Bickley; W. Watson

1999-01-01

Thomas Jefferson National Accelerator Facility's (Jefferson Lab) accelerator controls were initially implemented as a proprietary in-house system. During machine commissioning, problems were encountered leading to a decision to migrate to the Experimental Physics and Industrial Controls System (EPICS). Since then, the accelerator and all other laboratory controls have been successfully converted. In addition to implementing Jefferson Lab's controls using EPICS, new data visualization tools have been developed and existing programs have been enhanced with new capabilities. In order to provide a more generic interface for high level applications development, a device abstraction layer, called Common DEVice (CDEV), was implemented. These additions have been made available to other laboratories and are in use at many sites, including some that do not use EPICS. Control System development is not limited to computer scientists; operators, engineers and physicists frequently add capabilities using EPICS, CDEV, Tel/tk, and other tools. These contributions have tailored the control system for many different types of customers. For the future, the authors envision more intelligent processing and more capable tools for data storage, retrieval and visualization

The aim of this study was to evaluate the feasibility of the suggested trans-European methodology for undertaking representative dietary surveys among schoolchildren: 2 × 24-h dietary recalls (24-HDRs) combined with a food-recording booklet, using EPIC-Soft (the software developed to conduct 24-HDRs in the European Prospective Investigation into Cancer and Nutrition (EPIC) Study) pc-program. A total of 75 children aged 7-8 years and 70 children aged 12-13 years old were recruited through the Civil Registration System in Denmark, and 57 children aged 7-8 years and 47 children aged 12-13 years were recruited through schools in Spain. Each child with one parent completed two face-to-face 24-HDRs, combined with optional use of a food-recording booklet (FRB) to be filled in by the child, a parent or other proxy persons for preparing the recalls. Feasibility was evaluated by questionnaires completed by parents, children and interviewers, and by selected data from the 24-HDRs. The face-to-face interviews with the child and a parent together are confirmed as feasible. The children participated actively in the interviews, the oldest children being most active. The children, parents and interviewers agreed that children needed help from the parents, and that parents were of help to the child. In both countries, other proxy persons, such as teachers or the school cafeteria staff, were involved before the interview, and the majority of the parents and children reported that the FRB had been a help for the child during the interview. Further results point at specific needed improvements of the tools. The evaluated method is shown feasible in two culturally diverse European populations. However, the feasibility study also points to specific improvements of tools and data collection protocol that are strongly recommended before implementation of the method in each country of a pan-European dietary survey.

Sacrifice and self-sacrifice of Prince Lazar in the national epic from Christian and pagan aspects

Directory of Open Access Journals (Sweden)

Bojanić-Ćirković Mirjana D.

2014-01-01

Full Text Available This paper approaches the motives of sacrifice and self-sacrifice of Prince Lazar as a key to the construction of this epic character. At the beginning, consulting dictionaries and previous research, we determine the terminology and concepts of sacrifice self-sacrifice. Approaching the analysis of these motifs in the epic poems and accepting attitudes about their developmental line that ranges from medieval to folk literature, first search for Christian self-sacrifice. In the final part of the paper we provide a synthesis of Christian and pagan influence on the shaping of Lazarus motif of sacrifice and self-sacrifice with an emphasis on their share, hierarchy and function.

Previous studies have related poor glycemic control and/or some diabetes complications to low socioeconomic status. Some aspects of socioeconomic status have not been assessed in these studies. In the present study, we used an individual index of deprivation, the Evaluation de la Précarité et des Inégalités de santé dans les Centres d'Examens de Santé (Evaluation of Precarity and Inequalities in Health Examination Centers [EPICES]) score, to determine the relationship among glycemic control, diabetes complications, and individual conditions of deprivation. We conducted a cross-sectional prevalence study in 135 consecutive diabetic patients (age 59.41 +/- 13.2 years [mean +/- SD]) admitted in the hospitalization unit of a French endocrine department. Individual deprivation was assessed by the EPICES score, calculated from 11 socioeconomic questions. Glycemic control, lipid levels, blood pressure, retinopathy, neuropathy, and nephropathy were assessed. HbA(1c) level was significantly correlated with the EPICES score (r = 0.366, P < 0.001). The more deprived patients were more likely than the less deprived patients to have poor glycemic control (beta = 1.984 [SE 0.477], P < 0.001), neuropathy (odds ratio 2.39 [95% CI 1.05-5.43], P = 0.037), retinopathy (3.66 [1.39-9.64], P = 0.009), and being less often admitted for 1-day hospitalization (0.32 [0.14-0.74], P = 0.008). No significant relationship was observed with either nephropathy or cardiovascular risk factors. Deprivation status is associated with poor metabolic control and more frequent microvascular complications, i.e., retinopathy and neuropathy. The medical and economic burden of deprived patients is high.

The K2 Mission uses the Kepler spacecraft to obtain high-precision photometry over ≈80 day campaigns in the ecliptic plane. The Ecliptic Plane Input Catalog (EPIC) provides coordinates, photometry, and kinematics based on a federation of all-sky catalogs to support target selection and target management for the K2 mission. We describe the construction of the EPIC, as well as modifications and shortcomings of the catalog. Kepler magnitudes (Kp) are shown to be accurate to ≈0.1 mag for the Kepler field, and the EPIC is typically complete to Kp ≈ 17 (Kp ≈ 19 for campaigns covered by Sloan Digital Sky Survey). We furthermore classify 138,600 targets in Campaigns 1-8 (≈88% of the full target sample) using colors, proper motions, spectroscopy, parallaxes, and galactic population synthesis models, with typical uncertainties for G-type stars of ≈3% in {T}{{eff}}, ≈0.3 dex in {log} g, ≈40% in radius, ≈10% in mass, and ≈40% in distance. Our results show that stars targeted by K2 are dominated by K-M dwarfs (≈41% of all selected targets), F-G dwarfs (≈36%), and K giants (≈21%), consistent with key K2 science programs to search for transiting exoplanets and galactic archeology studies using oscillating red giants. However, we find significant variation of the fraction of cool dwarfs with galactic latitude, indicating a target selection bias due to interstellar reddening and increased contamination by giant stars near the galactic plane. We discuss possible systematic errors in the derived stellar properties, and differences with published classifications for K2 exoplanet host stars. The EPIC is hosted at the Mikulski Archive for Space Telescopes (MAST): http://archive.stsci.edu/k2/epic/search.php.

A development environment for the SSC control system

The SSC is developing a design environment for control system development within the context of EPICS. The environment is aimed at developers of applications using the EPICS Input/Output Controller (IOC). The unique aspect of this effort is our emphasis on providing a simple and intuitive development environment compared with tools currently available. Our most important goal in this effort has been to hide the complexity of EPICS IOC development from the developers. This paper describes two tools which are under development; The Function Block Editor (FBE) and the State Machine Editor (SME). The FBE provides a visual editing environment for graphically describing control processes as a set of related functional blocks. The configuration of functional blocks is then translated into IOC records and executed. SME allows the user to visually construct a sequence using a notation we are modeling after Grafcet [1]. State machines are translated into EPICS State Notation Language programs and executed. Future extensions will be described. ((orig.))

Effect of introduction of a new electronic anesthesia record (Epic) system on the safety and efficiency of patient care in a gastrointestinal endoscopy suite-comparison with historical cohort.

Goudra, B; Singh, P M; Borle, A; Gouda, G

2016-01-01

Use of electronic medical record systems has increased in the recent years. Epic is one such system gaining popularity in the USA. Epic is a private company, which invented the electronic documentation system adopted in our hospital. In spite of many presumed advantages, its use is not critically analyzed. Some of the perceived advantages are increased efficiency and protection against litigation as a result of accurate documentation. In this study, retrospective data of 305 patients who underwent endoscopic retrograde cholangiopancreatography (wherein electronic charting was used - "Epic group") were compared with 288 patients who underwent the same procedure with documentation saved on a paper chart ("paper group"). Time of various events involved in the procedure such as anesthesia start, endoscope insertion, endoscope removal, and transfer to the postanesthesia care unit were routinely documented. From this data, the various time durations were calculated. Both "anesthesia start to scope insertion" times and "scope removal to transfer" times were significantly less in the Epic group compared to the paper group. Use of Epic system led to a saving of 4 min of procedure time per patient. However, the mean oxygen saturation was significantly less in the Epic group. In spite of perceived advantages of Epic documentation system, significant hurdles remain with its use. Although the system allows seamless flow of patients, failure to remove all artifacts can lead to errors and become a source of potential litigation hazard.

Background How coffee consumption relates to mortality in diverse European populations, with variable coffee preparation methods and customs, is unclear. Objectives To examine whether coffee consumption is associated with all-cause and cause-specific mortality in men and women. Design Prospective cohort study. Setting Ten European countries. Participants A total of 521,330 men and women enrolled in the European Prospective Investigation into Cancer and Nutrition (EPIC). Main outcome measure Multivariable hazard ratios (HRs) and 95% confidence intervals(CIs) estimated using multivariable Cox proportional hazards models. The association of coffee with serum biomarkers of liver function, inflammation, and metabolic health was evaluated in the EPIC Biomarkers sub-cohort (n=14,800). Results During a mean follow-up of 16.4 years, 41,693 deaths occurred. Compared with non-consumers, participants in the highest quartile of coffee consumption experienced statistically significant lower all-cause mortality (Men: HR=0.88, 95%CI: 0.82–0.95; P-trendcoffee and circulatory disease mortality, (HR=0.78, 95%CI: 0.68–0.90; P-trendcoffee and ovarian cancer mortality (HR 1.12, 95% CI: 1.02–1.23 P-trend 0.001). In the EPIC-biomarkers sub-cohort, higher coffee consumption was associated with lower serum alkaline phosphatase, alanine transaminase, aspartate transaminase, and C-reactive protein. Limitation Reverse causality may have led to spurious findings; however, results did not differ following exclusion of participants who died within 8-years of baseline. The study is also limited by a single assessment of coffee drinking habits at baseline. Conclusions These results confirm prior findings on the reduced risk of mortality associated with coffee drinking but additionally show that this relationship does not vary by country where coffee preparation and drinking habits may differ. The study also reports novel inverse relationships between coffee drinking and digestive disease

In Helium Radio-Frequency Quadrupole (He RFQ) development, the role of the high-power Radio-Frequency (RF) is very important because it is responsible for stable delivery and efficient acceleration of the beam. Since the amplitude control requirements of LLRF system are ±1 % (amplitude), we need a precise remote control system for this reason. This system is referred to as Low-Level RF (LLRF) control system. This paper describes the basic configuration tasks performed by hardware side and the software side to build the LLRF control system, and describes the future work of the He RFQ LLRF control system based on this paper. LLRF control system development at the He RFQ development stage is important. LLRF control system development requires the exact configuration of hardware and software. For each of the Layer configuration is completed on the software side and hardware modules: vxworks operating system installation, EPICS BASE compilation, module source code compiled, object file loading and execution on vxworks, EPICS IOC operation check, etc.

Artificial intelligence tool development and applications to nuclear power

International Nuclear Information System (INIS)

Naser, J.A.

1987-01-01

Two parallel efforts are being performed at the Electric Power Research Institute (EPRI) to help the electric utility industry take advantage of the expert system technology. The first effort is the development of expert system building tools, which are tailored to electric utility industry applications. The second effort is the development of expert system applications. These two efforts complement each other. The application development tests the tools and identifies additional tool capabilities that are required. The tool development helps define the applications that can be successfully developed. Artificial intelligence, as demonstrated by the developments described is being established as a credible technological tool for the electric utility industry. The challenge to transferring artificial intelligence technology and an understanding of its potential to the electric utility industry is to gain an understanding of the problems that reduce power plant performance and identify which can be successfully addressed using artificial intelligence

to investigate hypothesised relationships between diet and cancer by assessing diet as a whole, in the Italian cohort EPIC. multicentric prospective study. 47,749 volunteers were recruited between 1993 and 1998 in the centres of Varese and Turin (Northern Italy), Florence (Central Italy), Naples and Ragusa (Southern Italy). Information on diet and lifestyle were collected through validated questionnaires. Anthropometric measurements were taken and biological samples collected using standardised protocols. follow-up was carried out by accessing regional cancer and mortality registries, hospital discharge records, and by telephone inquiries (only for Naples). After a median follow-up of 11 years, 879 incident cases of breast cancer, 421 cases of colorectal cancer, and 152 deaths were identified. Multivariate Cox regression models were used to estimate risks in relation to dietary characteristics. the "Olive oil & Salad" dietary pattern, characterised by high consumption of raw vegetables and olive oil, was associated with a lower risk of overall mortality in the elderly. Adherence to a Mediterranean diet rich in vegetables and fruit was associated with reduced risk of colon cancer. Consumption of high-glycemic carbohydrates was associated with higher incidence of breast cancer and colorectal cancer. Reduced risk of colon cancer was also found in regular consumers of yoghurt. the accuracy and comprehensiveness of EPIC-Italy data made it possible to investigate both individual dietary components and dietary habits as a whole, to thereby provide Italians with dietary and lifestyle advice that will help them to remain healthy.

Full Text Available Using the Research Development (R&D methodology, the study aimed to develop and validate WebQuests which can be used in literature subjects, particularly in the tertiary level to address the need of literature teachers for pedagogy in the teaching of epic s. The development of the Web Quests was anchored on the Theory of Constructivism. Two groups of experts validated the Web Quests – the literature experts and the ICT experts. The Content Validation Checklist, used by the literature experts, was utilized t o evaluate the content of the Web Quests. Meanwhile, the Rubric for Evaluating Web Quests, used by the ICT experts, was utilized to evaluate the design characteristics of the Web Quests. Computed weighted means using range interval of point scores were emp loyed to treat the data gathered from the evaluation conducted by both group of experts. The Web Quests developed contain five major parts which include: 1 introduction; 2 task; 3 process; 4 evaluation; and 5 conclusion. Based on the findings, the con tent of the Web Quests developed are valid in terms of objectives, activities and instructional characteristics. Likewise, the design characteristics of the Web Quests are excellent in terms of introductions, tasks, processes, resources, evaluations, concl usions and overall designs. Thus, the Web Quests developed are acceptable and can be utilized as instructional materials by literature teachers in the teaching of epics.

The NASA's Earth Polychromatic Imaging Camera (EPIC) onboard NOAA's Deep Space Climate Observatory (DSCOVR) mission was launched on February 11, 2015 to the Sun-Earth Lagrangian L1 point where it began to collect radiance data of the entire sunlit Earth at 16 km resolution (in equatorial zone) every 65 to 110 min in June 2015. It provides imageries in near backscattering directions with the scattering angle between 168o and 176o at ten UV to Near-IR narrow spectral bands centered at 317.5 (band width 1.0) nm, 325.0 (1.0) nm, 340.0 (3.0) nm, 388.0 (3.0) nm, 433.0 (3.0) nm, 551.0 (3.0) nm, 680.0 (1.7) nm, 687.8 (0.6) nm, 764.0 (1.7) nm and 779.5 (2.0) nm. This poster presents the theoretical basis of the algorithm designed for the generation of leaf area index (LAI) and diurnal course of sunlit leaf area index (SLAI) from EPIC Bidirectional Reflectance Factor of vegetated land. LAI and SLAI are defined as the total hemi-surface and sunlit leaf semi-surface per unit ground area. Whereas LAI is a standard product of many satellite the SLAI is a new satellite-derived parameter. Sunlit and shaded leaves exhibit different radiative response to incident Photosynthetically Active Radiation (400-700 nm), which in turn triggers various physiological and physical processes required for the functioning of plants. Leaf area and its sunlit portion are key state parameters in most ecosystem productivity and carbon/nitrogen cycle. Status of the EPIC LAI/SLAI product and its validation strategy are also discussed in this poster.

EPICS GPIB device support

International Nuclear Information System (INIS)

Winans, J.

1993-01-01

A GPIB device support module is used to provide access to the operating parameters of a GPIB device. GPIB devices may be accessed via National Instruments 1014 cards or via Bitbus Universal Gateways. GPIB devices typically have many parameters, each of which may be thought of in terms of the standard types of database records available in EPICS. It is the job of the device support module designer to decide how the mapping of these parameters will be made to the available record types. Once this mapping is complete, the device support module may be written. The writing of the device support module consists primarily of the construction of a parameter table. This table is used to associate the database record types with the operating parameters of the GPIB instrument. Other aspects of module design include the handling of SRQ events and errors. SRQ events are made available to the device support module if so desired. The processing of an SRQ event is completely up to the designer of the module. They may be ignored, tied to event based record processing, or anything else the designer wishes. Error conditions may be handled in a similar fashion

Retrieving Smoke Aerosol Height from DSCOVR/EPIC

Science.gov (United States)

Xu, X.; Wang, J.; Wang, Y.

2017-12-01

Unlike industrial pollutant particles that are often confined within the planetary boundary layer, smoke from forest and agriculture fires can inject massive carbonaceous aerosols into the upper troposphere due to the intense pyro-convection. Sensitivity of weather and climate to absorbing carbonaceous aerosols is regulated by the altitude of those aerosol layers. However, aerosol height information remains limited from passive satellite sensors. Here we present an algorithm to estimate smoke aerosol height from radiances in the oxygen A and B bands measured by the Earth Polychromatic Imaging Camera (EPIC) from the Deep Space Climate Observatory (DSCOVR). With a suit of case studies and validation efforts, we demonstrate that smoke aerosol height can be well retrieved over both ocean and land surfaces multiple times daily.

The health-related quality of life (HRQOL) after treatment of prostate cancer is examined using a new HRQOL tool. HRQOL, based on the expanded prostate cancer index composite (EPIC) and SF-8 questionnaires, was prospectively compared after either a radical retropubic prostatectomy (RRP) or a permanent prostate brachytherapy (PPB) at a single institute. Between October 2005 and June 2007, 96 patients were treated by an RRP and 88 patients were treated by a PPB. A HRQOL survey was completed at baseline, and at 1, 3, 6 and 12 months after treatment, prospectively. The general HRQOL in the RRP and PPB groups was not different after 3 months. However, at baseline and 1 month after treatment, the mental component summary was significantly better in the PPB group than in the RRP group. Moreover, the disease-specific HRQOL was worse regarding urinary and sexual functions in the RRP group. Urinary irritative/obstructive was worse in the PPB group, but urinary incontinence was worse in the RRP group and had not recovered to baseline after 12 months. The bowel function and bother were worse in the PPB group than in the RRP group after 3 months. In the RRP group, the patients with nerve sparing demonstrated the same scores in sexual function as the PPB group. This prospective study revealed the differences in the HRQOL after an RRP and PPB. Disease-specific HRQOL is clarified by using EPIC survey. These results will be helpful for making treatment decisions. (author)

Despite increasing interest in the concept of calibration in dietary surveys, there is still little experience in the use and standardization of a common reference dietary method, especially in international studies. In this paper, we present the general theoretical framework and the approaches developed to standardize the computer-assisted 24 h diet recall method (EPIC-SOFT) used to collect about 37 000 24-h dietary recall measurements (24-HDR) from the 10 countries participating in the European Prospective Investigation into Cancer and Nutrition (EPIC). In addition, an analysis of variance was performed to examine the level of standardization of EPIC-SOFT across the 90 interviewers involved in the study. The analysis of variance used a random effects model in which mean energy intake per interviewer was used as the dependent variable, while age, body mass index (BMI), energy requirement, week day, season, special diet, special day, physical activity and the EPIC-SOFT version were used as independent variables. The analysis was performed separately for men and women. The results show no statistical difference between interviewers in all countries for men and five out of eight countries for women, after adjustment for physical activity and the EPIC-SOFT program version used, and the exclusion of one interviewer in Germany (for men), and one in Denmark (for women). These results showed an interviewer effect in certain countries and a significant difference between gender, suggesting an underlying respondent's effect due to the higher under-reporting among women that was consistently observed in EPIC. However, the actual difference between interviewer and country mean energy intakes is about 10%. Furthermore, no statistical differences in mean energy intakes were observed across centres from the same country, except in Italy and Germany for men, and France and Spain for women, where the populations were recruited from areas scattered throughout the countries.

2005-01-01

At Jefferson Lab, we have been evaluating soft core processors running an EPICS IOC over μClinux on our custom hardware. A soft core processor is a flexible CPU architecture that is configured in the FPGA as opposed to a hard core processor which is fixed in silicon. Combined with an on-board Ethernet port, the technology incorporates the IOC and digital control hardware within a single FPGA. By eliminating the general purpose computer IOC, the designer is no longer tied to a specific platform, e.g. PC, VME, or VXI, to serve as the intermediary between the high level controls and the field hardware. This paper will discuss the design and development process as well as specific applications for JLab's next generation low-level RF controls and Machine Protection Systems

BURT: back up and restore tool

Energy Technology Data Exchange (ETDEWEB)

Karonis, N.T.

1994-11-01

BURT is just one of the tools in the Experimental Physics Industrial Control System (EPICS). In this document we address the problem of backing up and restoring sets of values in databases whose values are continuously changing. In doing so, we present the Back Up and Restore Tool (BURT). In this presentation we provide a theoretical framework that defines the problem and lays the foundation for its solution. BURT is a tool designed and implemented with respect to that theoretical framework. It is not necessary for users of BURT to have an understanding of that framework. It was included in this document only for the purpose of completeness. BURT`s basic purpose is to back up sets of values so that they can be later restored. Each time a back up is requested, a new ASCII file is generated. Further, the data values are stored as ASCII strings and therefore not compressed. Both of these facts conspire against BURT as a candidate for an archiver. Users who need an archiver should use a different tool, the Archiver.

This thesis is divided into two parts of improvements to the accelerator control system of the S-DALINAC. In the first part the finalisation of the EPICS migration to the S-DALINAC control system is presented. Therefore the input-outputcontrollers(IOCs) of the controls of magnets, the targets, and the video multiplexer are included into the EPICS framework. In addition to that the operator interfaces(OPIs) of the controls of magnets and targets are implemented. To configure these IOCs and OPIs a relational database is used, which was extended within this thesis. In- and output of magnet control is provided by rotating knobs and touch screens, which hardware were modernised. The realised steps are doing their part in reducing perturbations and ease up operations since. The second part covers the automated optimisation of beam optics. Therefore the software AreaDetector was integrated into the S-DALINAC control system. The functionality is shown by the example of setting a quadrupol magnet deflection-free fully automated. Also the flexibility enables other setups to be automatically optimised in the future.

To aid in assessing the functional performance of ITER, Fission Chambers (FC) based on the neutron diagnostic use case deliver timestamped measurements of neutron source strength and fusion power. To demonstrate the Plant System Instrumentation & Control (I&C) required for such a system, ITER Organization (IO) has developed a neutron diagnostics use case that fully complies with guidelines presented in the Plant Control Design Handbook (PCDH). The implementation presented in this paper has been developed on the PXI Express (PXIe) platform using products from the ITER catalog of standard I&C hardware for fast controllers. Using FlexRIO technology, detector signals are acquired at 125 MS/s, while filtering, decimation, and three methods of neutron counting are performed in real-time via the onboard Field Programmable Gate Array (FPGA). Measurement results are reported every 1 ms through Experimental Physics and Industrial Control System (EPICS) Channel Access (CA), with real-time timestamps derived from the ITER Timing Communication Network (TCN) based on IEEE 1588-2008. Furthermore, in accordance with ITER specifications for CODAC Core System (CCS) application development, the software responsible for the management, configuration, and monitoring of system devices has been developed in compliance with a new EPICS module called Nominal Device Support (NDS) and RIO/FlexRIO design methodology.

With the launch of the Deep Space Climate Observatory (DSCOVR), new estimates of the daytime Earth radiation budget can computed from a combination of measurements from the two Earth-observing sensors onboard the spacecraft, the Earth Polychromatic Imaging Camera (EPIC) and the National Institute of Standards and Technology Advanced Radiometer (NISTAR). Although these instruments can provide accurate top-of-atmosphere (TOA) radiance measurements, they lack sufficient resolution to provide details on small-scale surface and cloud properties. Previous studies have shown that these properties have a strong influence on the anisotropy of the radiation at the TOA, and ignoring such effects can result in large TOA-flux errors. To overcome these effects, high-resolution scene identification is needed for accurate Earth radiation budget estimation. Selected radiance and cloud property data measured and derived from several low earth orbit (LEO, including NASA Terra and Aqua MODIS, NOAA AVHRR) and geosynchronous (GEO, including GOES (east and west), METEOSAT, INSAT-3D, MTSAT-2, and HIMAWARI-8) satellite imagers were collected to create hourly 5-km resolution global composites of data necessary to compute angular distribution models (ADM) for reflected shortwave (SW) and longwave (LW) radiation. The satellite data provide an independent source of radiance measurements and scene identification information necessary to construct ADMs that are used to determine the daytime Earth radiation budget. To optimize spatial matching between EPIC measurements and the high-resolution composite cloud properties, LEO/GEO retrievals within the EPIC fields of view (FOV) are convolved to the EPIC point spread function (PSF) in a similar manner to the Clouds and the Earth's Radiant Energy System (CERES) Single Scanner Footprint TOA/Surface Fluxes and Clouds (SSF) product.

For the UNK Project a development of the Accelerator Control Applications is in the progress. These applications will use a specific Graphical User Interface for data presentation and accelerator parameter management. A number of tools have been developed based on the Motif Tool Kit. They contain a set of problem oriented screen templates and libraries. Using these tools, full scale prototype applications of the UNK Tune and Orbit measurement and correction were developed and are described, as examples. A subset of these allows the creation of the synoptic control screens from the Autocad pictures files and Oracle DB equipment descriptions. The basic concepts and a few application examples are presented. ((orig.))

computationally efficient than running multiple GCM or RCM simulations. Such a large ensemble of projections permits a description of a probability density function (PDF) of future climate states rather than a small number of individual story lines within that PDF, which may not be representative of the PDF as a whole; the EPIC method largely corrects for such potential sampling biases. The method is useful for providing projections of changes in climate to users wishing to investigate the impacts and implications of climate change in a probabilistic way. A web-based tool, using the EPIC method to provide probabilistic projections of changes in daily maximum and minimum temperatures for New Zealand, has been developed and is described in this paper.

Poetry’s Politics in Archaic Greek Epic and Lyric

Directory of Open Access Journals (Sweden)

David F. Elmer

2013-03-01

Full Text Available This essay builds on work in The Poetics of Consent (2013, which argues that the Iliad’s representation of politics reflects the workings of the oral tradition underlying the poem as we have it, a tradition that developed in the context of Panhellenic festivals. Applying a similar perspective to poetry belonging to the very different performative context of the symposium, this essay draws evidence from Theognis and Alcaeus suggesting that the social dynamics of sympotic performance could be expressed in terms of political fragmentation and alienation. In the Odyssey, the contrast between the epic singers Phemios and Demodokos reflects an awareness of the difference between these performative contexts.

Erasmus Darwin's Deistic Dissent and Didactic Epic Poetry: Promoting Science Education to a Mixed Audience Under the Banner of Tolerance

Science.gov (United States)

Martin, Kirsten Anne

Erasmus Darwin's task as a Deistic Dissenter poet who wished to promote science education to a mixed audience was complex. There was mainstream concern over what Deists and Dissenters actually believed about God, their involvement in science, and, especially, how their published works, whatever the subject, might affect public morality and politics. I argue that Darwin's poetry is primarily in the genre of Lucretian didactic epic but that it also involves elements of other written traditions (literary and non-literary). I focus on English didactic poetry, the theological written traditions of Dissent and Deism, and a particular tradition of erotic satire. The genre of Lucretian didactic epic and the tradition of English didactic poetry are non-identical. In Darwin's Lucretian didactic epic, resemblances to such poems as Pope's Essay on Man challenge ideas about what kind of narrative a didactic poem in the English language can deliver. Techniques from the theological written traditions of Dissent and Deism reflect Darwin's affiliations, signal that science education fits within a larger debate about intellectual freedom, and promote tolerance for differences of opinion about nature. Mimicry of a particular tradition of erotic satire helps to downplay the address to a mixed audience while satirising some common misconceptions about poetry, botany, and women in the period. Darwin's poetry challenges ideas about what people from his community of belief meant to communicate or transmit by writing for the general public, what the general public was entitled to learn, and what poetry was able to teach. Perhaps Darwin's biggest modification of Lucretian didactic epic was that he did not tell his readers exactly what to think, but how.

Jackson, M J; Sein, H; Ahmed, W; Woodwards, R

2007-01-01

The application of diamond coatings on cemented tungsten carbide (WC-Co) tools has been the subject of much attention in recent years in order to improve cutting performance and tool life in orthodontic applications. WC-Co tools containing 6% Co metal and 94% WC substrate with an average grain size of 1 - 3 microm were used in this study. In order to improve the adhesion between diamond and WC substrates it is necessary to etch cobalt from the surface and prepare it for subsequent diamond growth. Alternatively, a titanium nitride (TiN) interlayer can be used prior to diamond deposition. Hot filament chemical vapour deposition (HFCVD) with a modified vertical filament arrangement has been employed for the deposition of diamond films to TiN and etched WC substrates. Diamond film quality and purity has been characterized using scanning electron microscopy (SEM) and micro Raman spectroscopy. The performances of diamond-coated WC-Co tools, uncoated WC-Co tools, and diamond embedded (sintered) tools have been compared by drilling a series of holes into various materials such as human tooth, borosilicate glass, and acrylic tooth materials. Flank wear has been used to assess the wear rates of the tools when machining biomedical materials such as those described above. It is shown that using an interlayer such as TiN prior to diamond deposition provides the best surface preparation for producing dental tools.

The European Prospective Investigation into Cancer and Nutrition (EPIC), which has been established in order to investigate the relations between nutrition and cancer, was initiated in 1990 and involves 10 European countries with heterogeneous dietary patterns and differing cancer incidence rates. This manuscript presents the design, recruitment and baseline characteristics of the Prospect-EPIC cohort co-ordinated in Utrecht, The Netherlands. The cohort is based on volunteers recruited among women participating in a regional breast cancer screening program. It comprises of 17,357 subjects aged 50-69 years at enrolment from Utrecht and vicinity, who have consented to participate in the study and its follow-up. Each participant filled out a general questionnaire and a food frequency questionnaire. Participants were also physically examined and have donated a blood sample. Participation rate was 34.5%. Blood samples were donated by most participants (97.5%) and detailed informed consents were obtained from 87.4% of participants. Mean age at enrolment was 57 years. Anthropometric, lifestyle and morbidity characteristics of the cohort population did not differ largely from those of similar study populations in The Netherlands. Based on the Prospect-EPIC population, we intend to conduct prospective total cohort, nested case-control or case-cohort studies, in order to investigate relations between consumption of certain food groups or nutrients and chronic diseases, including hormone dependant cancers such as breast, colon, endometrial and ovary cancers.

The NASA's Earth Polychromatic Imaging Camera (EPIC) onboard NOAA's Deep Space Climate Observatory (DSCOVR) mission was launched on February 11, 2015 to the Sun-Earth Lagrangian L1 point where it began to collect radiance data of the entire sunlit Earth every 65 to 110 min in June 2015. It provides imageries in near backscattering directions with the scattering angle between 168° and 176° at ten ultraviolet to near infrared (NIR) narrow spectral bands centered at 317.5 (band width 1.0) nm, 325.0 (2.0) nm, 340.0 (3.0) nm, 388.0 (3.0) nm, 433.0 (3.0) nm, 551.0 (3.0) nm, 680.0 (3.0) nm, 687.8 (0.8) nm, 764.0 (1.0) nm and 779.5 (2.0) nm. This poster presents current status of the Vegetation Earth System Data Record of global Leaf Area Index (LAI), solar zenith angle dependent Sunlit Leaf Area Index (SLAI), Fraction vegetation absorbed Photosynthetically Active Radiation (FPAR) and Normalized Difference Vegetation Index (NDVI) derived from the DSCOVR EPIC observations. Whereas LAI is a standard product of many satellite missions, the SLAI is a new satellite-derived parameter. Sunlit and shaded leaves exhibit different radiative response to incident Photosynthetically Active Radiation (400-700 nm), which in turn triggers various physiological and physical processes required for the functioning of plants. FPAR, LAI and SLAI are key state parameters in most ecosystem productivity models and carbon/nitrogen cycle. The product at 10 km sinusoidal grid and 65 to 110 min temporal frequency as well as accompanying Quality Assessment (QA) variables will be publicly available from the NASA Langley Atmospheric Science Data Center. The Algorithm Theoretical Basis (ATBD) and product validation strategy are also discussed in this poster.

Mapping Romanzo Criminale. An Epic Narrative Ecosystem?

Directory of Open Access Journals (Sweden)

Marta Boni

2015-05-01

Full Text Available Romanzo Criminale is one of the few recent Italian media products that has emerged as a societal phenomenon and as a vehicle for the exportation of a national culture. It is a complex narrative which extends in time and space due to its various adaptations and intermedial crossovers. Following the path of complexity, drawing on Edgar Morin’s work, Romanzo Criminale will be thought of as a complex system. As precedent studies on the intertwining of official and grassroots discourses show, Romanzo Criminale becomes a complex world, with its boundaries and internal organization. This paper will show that Romanzo Criminale can be studied as a semiosphere (Lotman 2005, or a semiotic space defined by and which encourages the intertwining of texts and audience appropriations, creating an epic process. Some methodological perspectives used for mapping this phenomenon will be discussed, namely Franco Moretti’s distant reading.

Los Alamos National Laboratory has been working with National Instruments (NI) and Cosy lab to implement EPICS Input Output Controller (IOC) software that runs directly on NI CompactRIO Real Time Controller (RTC) and communicates with NI LabVIEW through a shared memory interface. In this presentation, we will discuss our current progress in upgrading the control system at the Los Alamos Neutron Science Centre (LANSCE) and what we have learned about integrating CompactRIO into large experimental physics facilities. We will also discuss the implications of using Channel Access Server for LabVIEW which will enable more commercial hardware platforms to be used in upgrading existing facilities or in commissioning new ones.

The spectral invariant approximation within canopy radiative transfer to support the use of the EPIC/DSCOVR oxygen B-band for monitoring vegetation

International Nuclear Information System (INIS)

Marshak, Alexander; Knyazikhin, Yuri

2017-01-01

EPIC (Earth Polychromatic Imaging Camera) is a 10-channel spectroradiometer onboard DSCOVR (Deep Space Climate Observatory) spacecraft. In addition to the near-infrared (NIR, 780 nm) and the ‘red’ (680 nm) channels, EPIC also has the O2 A-band (764±0.2 nm) and B-band (687.75±0.2 nm). The EPIC Normalized Difference Vegetation Index (NDVI) is defined as the difference between NIR and ‘red’ channels normalized to their sum. However, the use of the O2 B-band instead of the ‘red’ channel mitigates the effect of atmosphere on remote sensing of surface reflectance because O2 reduces contribution from the radiation scattered by the atmosphere. Applying the radiative transfer theory and the spectral invariant approximation to EPIC observations, the paper provides supportive arguments for using the O2 band instead of the red channel for monitoring vegetation dynamics. Our results suggest that the use of the O2 B-band enhances the sensitivity of the top-of-atmosphere NDVI to the presence of vegetation. - Highlights: • The use of the O2 B-band channel (688 nm) instead of the red channel (680 nm) mitigates the effect of atmosphere on remote sensing of surface reflectance. • The spectral invariant approach confirms that the synergy of the green, O2 B-band and near IR channels mimics spectral properties of vegetation. • The structural parameter of vegetation retrieved remotely is weakly sensitive to the uncertainty in the atmospheric optical depth.

Phytosterol intake with natural foods, a measure of healthy dietary choices, increases plasma levels, but increased plasma phytosterols are believed to be a coronary heart disease (CHD) risk factor. To address this paradox, we evaluated baseline risk factors, phytosterol intake, and plasma noncholesterol sterol levels in participants of a case control study nested within the European Prospective Investigation into Cancer and Nutrition (EPIC) Spanish cohort who developed CHD (n = 299) and matched controls (n = 584) who remained free of CHD after a 10 year follow-up. Sitosterol-to-cholesterol ratios increased across tertiles of phytosterol intake (P = 0.026). HDL-cholesterol level increased, and adiposity measures, cholesterol/HDL ratios, and levels of glucose, triglycerides, and lathosterol, a cholesterol synthesis marker, decreased across plasma sitosterol tertiles (P phytosterol intake and plasma sitosterol. The multivariable-adjusted odds ratio for CHD across the lowest to highest plasma sitosterol tertile was 0.59 (95% confidence interval, 0.36–0.97). Associations were weaker for plasma campesterol. The apolipoprotein E genotype was unrelated to CHD risk or plasma phytosterols. The data suggest that plasma sitosterol levels are associated with a lower CHD risk while being markers of a lower cardiometabolic risk in the EPIC-Spain cohort, a population with a high phytosterol intake.

Black-Right-Pointing-Pointer Increasing control parameters will not increase consumed time neither complexity. Black-Right-Pointing-Pointer IQ demodulation can be achieved thanks to the transformed values at driver level. - Abstract: The IFMIF-EVEDA (International Fusion Materials Irradiation Facility - Engineering Validation and Engineering Design Activity) linear accelerator, known as Linear IFMIF Prototype Accelerator (LIPAc), will be a 9 MeV, 125 mA continuous wave (CW) deuteron accelerator prototype to validate the technical options of the accelerator design for IFMIF. The primary mission of such facility is to test and verify materials performance when subjected to extensive neutron irradiation of the type encountered in a fusion reactor to prepare for the design, construction, licensing and safe operation of a fusion demonstration reactor (DEMO). The radio frequency (RF) power system of IFMIF-EVEDA consists of 18 RF chains working at 175 MHz with three amplification stages each. The low-level radio frequency (LLRF) controls the amplitude and phase of the signal to be synchronized with the beam and it also controls the resonance frequency of the cavities. The system is based on a commercial compact peripheral component interconnect (cPCI) field programmable gate array (FPGA) board, provided by Lyrtech and controlled by a Windows host PC. For this purpose, it is mandatory to communicate the cPCI FPGA board from EPICS Channel Access [1]. A software architecture on EPICS framework in order to control and monitor the LLRF system is presented.

DAMT - DISTRIBUTED APPLICATION MONITOR TOOL (HP9000 VERSION)

Keith, B.

1994-01-01

Typical network monitors measure status of host computers and data traffic among hosts. A monitor to collect statistics about individual processes must be unobtrusive and possess the ability to locate and monitor processes, locate and monitor circuits between processes, and report traffic back to the user through a single application program interface (API). DAMT, Distributed Application Monitor Tool, is a distributed application program that will collect network statistics and make them available to the user. This distributed application has one component (i.e., process) on each host the user wishes to monitor as well as a set of components at a centralized location. DAMT provides the first known implementation of a network monitor at the application layer of abstraction. Potential users only need to know the process names of the distributed application they wish to monitor. The tool locates the processes and the circuit between them, and reports any traffic between them at a user-defined rate. The tool operates without the cooperation of the processes it monitors. Application processes require no changes to be monitored by this tool. Neither does DAMT require the UNIX kernel to be recompiled. The tool obtains process and circuit information by accessing the operating system's existing process database. This database contains all information available about currently executing processes. Expanding the information monitored by the tool can be done by utilizing more information from the process database. Traffic on a circuit between processes is monitored by a low-level LAN analyzer that has access to the raw network data. The tool also provides features such as dynamic event reporting and virtual path routing. A reusable object approach was used in the design of DAMT. The tool has four main components; the Virtual Path Switcher, the Central Monitor Complex, the Remote Monitor, and the LAN Analyzer. All of DAMT's components are independent, asynchronously executing

Experiences in messaging middle-ware for high-level control applications

Existing high-level applications in accelerator control and modeling systems leverage many different languages, tools and frameworks that do not inter-operate with one another. As a result, the accelerator control community is moving toward the proven Service-Oriented Architecture (SOA) approach to address the inter-operability challenges among heterogeneous high-level application modules. Such SOA approach enables developers to package various control subsystems and activities into 'services' with well-defined 'interfaces' and make leveraging heterogeneous high-level applications via flexible composition possible. Examples of such applications include presentation panel clients based on Control System Studio (CSS) and middle-layer applications such as model/data servers. This paper presents our experiences in developing a demonstrative high-level application environment using emerging messaging middle-ware standards. In particular, we utilize new features in EPICS v4 and other emerging standards such as Data Distribution Service (DDS) and Extensible Type Interface by the Object Management Group. We first briefly review examples we developed previously. We then present our current effort in integrating DDS into such a SOA environment for control systems. Specifically, we illustrate how we are integrating DDS into CSS and develop a Python DDS mapping. (authors)

EPIC models fuel and coolant motion which result from internal fuel pin pressure (from fission gas or fuel vapor) and/or from the generation of sodium vapor pressures in the coolant channel subsequent to pin failure in an LMFBR. The modeling includes the ejection of molten fuel from the pin into a coolant channel with any amount of voiding through a clad rip which may be of any length or which may expand with time. One-dimensional Eulerian hydrodynamics is used to model both the motion of fuel and fission gas inside a molten fuel cavity and the mixture of two-phase sodium and fission gas in the channel. Motion of molten fuel particles in the coolant channel is tracked with a particle-in-cell technique

Background/Objective Fruit and vegetable intake (FVI) may reduce the risk of type 2 diabetes (T2D), but the epidemiological evidence is inconclusive. The aim of this study is to examine the prospective association of FVI with T2D and conduct an updated meta-analysis. Subjects/Methods In the EPIC-InterAct (European Prospective Investigation into Cancer-InterAct) prospective case-cohort study nested within eight European countries, a representative sample of 16 154 participants and 12 403 incident cases of T2D were identified from 340 234 individuals with 3.99 million person-years of follow-up. For the meta-analysis we identified prospective studies on FVI and T2D risk by systematic searches of MEDLINE and EMBASE until April 2011. Results In EPIC-InterAct, estimated FVI by dietary questionnaires varied more than two-fold between countries. In adjusted analyses the hazard ratio (95% confidence interval) comparing the highest with lowest quartile of reported intake was 0.90 (0.80-1.01) for FVI; 0.89 (0.76-1.04) for fruit, and 0.94 (0.84-1.05) for vegetables. Among FV sub-types, only root vegetables were inversely associated with diabetes 0.87 (0.77-0.99). In meta-analysis using pooled data from five studies including EPIC-InterAct, comparing the highest with lowest category for FVI was associated with a lower relative risk of diabetes (0.93 (0.87-1.00)). Fruit or vegetables separately were not associated with diabetes. Among FV sub-types, only green leafy vegetable intake (RR: 0.84 (0.74-0.94)) was inversely associated with diabetes. Conclusions Sub-types of vegetables, such as root vegetables or green leafy vegetables may be beneficial for the prevention of diabetes, while total FVI may exert a weaker overall effect.

Large-scale longitudinal data on the association of domain-specific physical activity (PA) and mortality is limited. Our objective was to evaluate the association of work, household (HPA), and leisure time PA (LTPA) with overall and cause-specific mortality in the EPIC-Spain study. 38,379 participants (62.4% women), 30-65years old, and free of chronic disease at baseline were followed-up from recruitment (1992 - 1996) to December 31st, 2008 to ascertain vital status and cause of death. PA was evaluated at baseline and at a 3-year follow-up with a validated questionnaire (EPIC-PAQ) and combined variables were used to classify the participants by sub-domains of PA. Associations with overall, cancer, and cardiovascular mortality risks were assessed using competing risk Cox regression models adjusted by potential confounders. After 13.6years of mean follow-up, 1371 deaths were available for analyses. HPA was strongly associated to reduced overall (hazard ratio (HR) for Q4 vs. Q1=0.47 (0.34, 0.64)) and cause-specific mortalities in women and to lower cancer mortality in men (P for trend=0.004), irrespective of age, education, and lifestyle and morbidity variables. LTPA was associated with lower mortality in women (HR for Q4 vs. Q1=0.71 (0.52, 0.98)), but not men. No relationships were found between sedentariness at work and overall mortality. HPA was associated to lower mortality risk in men and women from the EPIC-Spain cohort, whereas LTPA also contributed to reduce risk of death in women. Considering the large proportion of total daily PA that HPA represents in some population groups, these results are of public health importance. Copyright © 2016 Elsevier Inc. All rights reserved.

Remote controlled tool systems for nuclear sites have subsea applications

1995-10-01

Remotely operated underwater tool systems designed to operate in Nuclear Fuel Storage Basins can be applied to deep water, subsea oilfield applications. Spent nuclear fuel rods re stored underwater in large indoor swimming pool-like facilities where the water cover shields the workers from the radiation. This paper describes three specialized tooling systems that were designed and built by Sonsub for work at the Department of Energy's Hanford site. The Door Seal Tool removed an existing seal system, cleaned a 20 ft. tall, carbon steel, underwater hatch and installed a new stainless steel gasket surface with underwater epoxy. The Concrete Sampling Tool was built to take core samples from the vertical, concrete walls of the basins. The tool has three hydraulic drills with proprietary hollow core drill bits to cut and retrieve the concrete samples. The Rack Saw remotely attached itself to a structure, cut a variety of steel shapes and pipes, and retained the cut pieces for retrieval. All of these systems are remotely operated with onboard video cameras and debris collection systems. The methods and equipment proven in this application are available to refurbish sealing surfaces and to drill or sample concrete in offshore oil field applications

2012-01-01

The ubiquitousness of web clients from personal computers to cell phones results in a growing demand for web-based access to control system data. At the Oak Ridge National Laboratory Spallation Neutron Source (SNS) we have investigated different technical approaches to provide read access to data in the Experimental Physics and Industrial Control System (EPICS) for a wide variety of web client devices. The core web technology, HTTP, is less than ideal for online control system displays. Appropriate use of Ajax, especially the Long Poll paradigm, can alleviate fundamental HTTP limitations. The SNS Status web uses basic Ajax technology to generate generic displays for a wide audience. The Dashboard uses Long Poll and more client-side Java-Script to offer more customization and faster updates for users that need specialized displays. The Web OPI uses RAP for web access to any BOY display, offering utmost flexibility because users can create their own BOY displays in CSS. These three approaches complement each other. Users can access generic status displays with zero effort, invest time in creating their fully customized displays for the Web OPI, or use the Dashboard as an intermediate solution

To evaluate the consumption of added fats and oils across the European centres and countries participating in the European Prospective Investigation into Cancer and Nutrition (EPIC). 24-Hour dietary recalls were collected by means of standardised computer-guided interviews in 27 redefined EPIC centres across 10 European countries. From an initial number of 36 900 subjects, single dietary recalls from 22 924 women and 13 031 men in the age range of 35-74 years were included. Mean daily intake of added fats and oils varied between 16.2 g (Varese, Italy) and 41.1 g (Malmö, Sweden) in women and between 24.7 g (Ragusa, Italy) and 66.0 g (Potsdam, Germany) in men. Total mean lipid intake by consumption of added fats and oils, including those used for sauce preparation, ranged between 18.3 (Norway) and 37.2 g day-1 (Greece) in women and 28.4 (Heidelberg, Germany) and 51.2 g day-1 (Greece) in men. The Mediterranean EPIC centres with high olive oil consumption combined with low animal fat intake contrasted with the central and northern European centres where fewer vegetable oils, more animal fats and a high proportion of margarine were consumed. The consumption of added fats and oils of animal origin was highest in the German EPIC centres, followed by the French. The contribution of added fats and oils to total energy intake ranged from 8% in Norway to 22% in Greece. The results demonstrate a high variation in dietary intake of added fats and oils in EPIC, providing a good opportunity to elucidate the role of dietary fats in cancer aetiology.

1996-01-01

The CEBAF accelerator at Thomas Jefferson National Accelerator Facility (Jefferson Lab) successfully began its experimental nuclear physics program in November of 1995 and has since surpassed predicted machine availability. Part of this success can be attributed to using the EPICS (Experimental Physics and Industrial Control System) control system toolkit. The CEBAF control system is one of the largest accelerator control system now operating. It controls approximately 338 SRF cavities, 2,300 magnets, 500 beam position monitors and other accelerator devices, such as gun hardware and other beam monitoring devices. All told, the system must be able to access over 125,000 database records. The system has been well received by both operators and the hardware designers. The EPICS utilities have made the task of troubleshooting systems easier. The graphical and test-based creation tools have allowed operators to custom build control screens. In addition, the ability to integrate EPICS with other software packages, such as Tcl/Tk, has allowed physicists to quickly prototype high-level application programs, and to provide GUI front ends for command line driven tools. Specific examples of the control system applications are presented in the areas of energy and orbit control, cavity tuning and accelerator tune up diagnostics

Applications of computational tools in biosciences and medical engineering

CERN Document Server

Altenbach, Holm

2015-01-01

 This book presents the latest developments and applications of computational tools related to the biosciences and medical engineering. It also reports the findings of different multi-disciplinary research projects, for example, from the areas of scaffolds and synthetic bones, implants and medical devices, and medical materials. It is also shown that the application of computational tools often requires mathematical and experimental methods. Computational tools such as the finite element methods, computer-aided design and optimization as well as visualization techniques such as computed axial tomography open up completely new research fields that combine the fields of engineering and bio/medical. Nevertheless, there are still hurdles since both directions are based on quite different ways of education. Often even the “language” can vary from discipline to discipline.

In Search of a National Epic: The use of Old Norse myths in Tolkien's vision of Middle-earth

Directory of Open Access Journals (Sweden)

Tommy Kuusela

2014-05-01

Full Text Available In this article some aspects of Tolkien’s work with regard to his relationship to folklore and nationalism are presented. It is also argued, contrary to Lauri Honko’s view of literary epics, that pre-literary sources constitute a problem for the creators of literary epics and that their elements can direct the choice of plot and form. Tolkien felt that there was a British – but no English – mythology comparable to the Greek, Finnish or Norse ones. He tried to reconstruct the ‘lost mythology’ with building blocks from existing mythologies, and dedicated his work to the English people. In this, he saw himself as a compiler of old source material. This article considers his use of Old Norse sources. With Honko’s notion of the second life of folklore it is argued that Tolkien managed to popularise folklore material while his efforts to make his work exclusively English failed; for a contemporary audience it is rather cross-cultural.

Optogenetic Tools for Subcellular Applications in Neuroscience.

Rost, Benjamin R; Schneider-Warme, Franziska; Schmitz, Dietmar; Hegemann, Peter

2017-11-01

The ability to study cellular physiology using photosensitive, genetically encoded molecules has profoundly transformed neuroscience. The modern optogenetic toolbox includes fluorescent sensors to visualize signaling events in living cells and optogenetic actuators enabling manipulation of numerous cellular activities. Most optogenetic tools are not targeted to specific subcellular compartments but are localized with limited discrimination throughout the cell. Therefore, optogenetic activation often does not reflect context-dependent effects of highly localized intracellular signaling events. Subcellular targeting is required to achieve more specific optogenetic readouts and photomanipulation. Here we first provide a detailed overview of the available optogenetic tools with a focus on optogenetic actuators. Second, we review established strategies for targeting these tools to specific subcellular compartments. Finally, we discuss useful tools and targeting strategies that are currently missing from the optogenetics repertoire and provide suggestions for novel subcellular optogenetic applications.

Full Text Available La atractiva apariencia de la madera de Cordia alliodora (laurel, sus características físico-mecánicas, su abundante regeneración natural, captura de carbono y protección al suelo, la hacen ideal para la reforestación. No obstante, la falta de material de siembra de buena calidad para suplir la demanda media anual, convierten la propagación vegetativa en una herramienta esencial para el mejoramiento genético, y la conservación de genotipos en bancos clonales. En este sentido, se propuso establecer una metodología para la inducción y enraizamiento de brotes epicórmicos de árboles de laurel utilizando reguladores de crecimiento vegetal. Las concentraciones de citoquininas empleadas para la inducción de brotes a partir de árboles adultos fueron de: 0, 3000, 6000, 9000 mg L-1 de BAP sola y combinadas con 1000, 2000, 3000 mg L-1 de AIA, y se determinaron utilizando un Diseño Completo Aleatorizado (DCA. Las concentraciones de auxinas para el enraizamiento de los brotes fueron de 0, 1000, y 1500 mg kg-1 de ANA y AIB, mediante un DCA con arreglo factorial 3 x 3 (hormona ANA x hormona AIB. Se evaluó la inducción de brotes epicórmicos y se obtuvieron 2.67 brotes de 16.42 cm de longitud, con 6000 mg kg-1 de BAP + 2000 mg kg-1 de AIA. El porcentaje de enraizamiento fue 54%, número de raíces 1.78, longitud 2.59 con 1500 mg kg-1 de ANA + 1500 mg kg-1 de AIB. El uso de citoquininas y auxinas fue efectivo para provocar la diferenciación celular tanto en la inducción y rizogénesis de brotes epicórmicos de laurel.

‘Eastern’ Elegy and ‘Western’ Epic: reading ‘orientalism’ in Propertius 4 and Virgil’s Aeneid

Directory of Open Access Journals (Sweden)

Donncha O’Rourke

2011-11-01

Full Text Available This article explores the extent to which the genres of epic and elegy can be considered ‘occidental’ and ‘oriental’ respectively. Such a polarity is apparently constructed in the ‘epic’ and ‘elegiac’ movements of Propertius 4.1, but it is also progressively deconstructed in Propertius’ reception of Virgil’s Aeneid in elegies 4.1, 4.6 and 4.9. On the one hand, Propertius reads the Aeneid for its oriental components (e.g. the Phrygian immigration as viewed by native Italy ; its oriental ‘heroines’ : Dido, Cleopatra and, if the episode to which she lends her name is not an interpolation, Helen. On the other hand, Propertian elegy has for its part become more occidental (Propertius sings of maxima Roma and the Roman victory at Actium ; Cynthia is dead. In this way, Propertius shows that the narrative of elegy is no less bound up with occidental hegemony than that of Virgilian epic, and that elegy’s literary exoticism is, like Virgil’s intertextual appropriation of Greek literature, itself contingent on Roman imperialism.

Pizzica, P.A.; Garner, P.L.; Abramson, P.B.

The computer code EPIC models fuel and coolant motion which results from internal fuel pin pressure (from fission gas or fuel vapor) and possibly from the generation of sodium vapor pressure in the coolant channel subsequent to pin failure in a liquid-metal fast breeder reactor. The EPIC model is restricted to conditions where fuel pin geometry is generally preserved and is not intended to treat the total disruption of the pin structure. The modeling includes the ejection of molten fuel from the pin into a coolant channel with any amount of voiding through a clad breach which may be of any length or which may extend with time. One-dimensional Eulerian hydrodynamics is used to treat the motion of fuel and fission gas inside a molten fuel cavity in the fuel pin as well as the mixture of two-phase sodium and fission gas in the coolant channel. Motion of fuel in the coolant channel is tracked with a type of particle-in-cell technique. EPIC is a Fortran-IV program requiring 400K bytes of storage on the IBM 370/195 computer. 21 refs., 2 figs.

Enabling Future Large Searches for Exoplanet Auroral Emission with the EPIC Correlator Architecture

Science.gov (United States)

Thyagarajan, Nithyanandan; Beardsley, Adam P.; Bowman, Judd D.; Morales, Miguel F.

2017-05-01

Extrasolar planets are expected to emit strong ``auroral'' emission at radio frequencies generated by the interaction of the host star's stellar winds with the planet's magnetosphere through electron-cyclotron maser emission. This transient emission lasts a few seconds to days and is almost fully circularly polarized. Detecting this emission in exoplanets is a critical probe of their magnetospheres and thus their interior compositions and habitability. The intensity and detectability of the emission depends on the suitability of many factors to the observing parameters such as the strength of the stellar wind power, the planetary magnetosphere cross-section, the highly beamed and coherent nature of electron-cyclotron emission, and narrow ranges of the planet's orbital phase. Large areas of sky must be surveyed continuously to high sensitivity to detect auroral emission. Next-generation radio telescopes with wide fields of view, large collecting areas and high efficiency are needed for these searches. This poses challenges to traditional correlator architectures whose computational cost scales as the square of the number of antennas. I will present a novel radio aperture synthesis imaging architecture - E-field Parallel Imaging Correlator (EPIC) - whose all-sky and full Stokes imaging capabilities will not only address the aforementioned factors preventing detection but also solve the computational challenges posed by large arrays. Compared to traditional imaging, EPIC is inherently fast and thus presents the unique advantage of probing transient timescales ranging orders of magnitude from tens of microseconds to days at no additional cost.

An Analysis of Pulsating Subdwarf B Star EPIC 203948264 Observed During Campaign 2 of K2

Full Text Available We present a preliminary analysis of the newly–discovered pulsating subdwarf B (sdB star EPIC 203948264. The target was observed for 83 days in short cadence mode during Campaign 2 of K2, the two–gyro mission of the Kepler space telescope. A time–series analysis of the data revealed 22 independent pulsation frequencies in the g–mode region ranging from 100 to 600 μHz (0:5 to 2:8 hours. The main method we use to identify pulsation modes is asymptotic period spacing, and we were able to assign all but one of the pulsations to either l = 1 or l = 2. The average period spacings of both sequences are 261:34 ± 0.78 s and 151:18 ± 0.34 s, respectively. The pulsation amplitudes range from 0.77 ppt down to the detection limit at 0.212 ppt, and are not stable over the duration of the campaign. We detected one possible low–amplitude, l = 2, rotationally split multiplet, which allowed us to constrain the rotation period to 46 days or longer. This makes EPIC 203948264 another slowly rotating sdB star.

Owing to peculiar properties of nanobody, including nanoscale size, robust structure, stable and soluble behaviors in aqueous solution, reversible refolding, high affinity and specificity for only one cognate target, superior cryptic cleft accessibility, and deep tissue penetration, as well as a sustainable source, it has been an ideal research tool for the development of sophisticated nanobiotechnologies. Currently, the nanobody has been evolved into versatile research and application tool kits for diverse biomedical and biotechnology applications. Various nanobody-derived formats, including the nanobody itself, the radionuclide or fluorescent-labeled nanobodies, nanobody homo- or heteromultimers, nanobody-coated nanoparticles, and nanobody-displayed bacteriophages, have been successfully demonstrated as powerful nanobiotechnological tool kits for basic biomedical research, targeting drug delivery and therapy, disease diagnosis, bioimaging, and agricultural and plant protection. These applications indicate a special advantage of these nanobody-derived technologies, already surpassing the "me-too" products of other equivalent binders, such as the full-length antibodies, single-chain variable fragments, antigen-binding fragments, targeting peptides, and DNA-based aptamers. In this review, we summarize the current state of the art in nanobody research, focusing on the nanobody structural features, nanobody production approach, nanobody-derived nanobiotechnology tool kits, and the potentially diverse applications in biomedicine and biotechnology. The future trends, challenges, and limitations of the nanobody-derived nanobiotechnology tool kits are also discussed.

Full Text Available The Heroism of women in the African Epic: A critical analysis of Sundiata or the mandingo Epic, Emperor Shaka The Great: A Zulu Epic and Nsongo’a Lianja: The national Epic of the Nkundo. In African epics, female figures perform salient heroic roles that are, unfortunately, not widely recognised and celebrated, as notions of bravery and heroism are understood from a male perspective. Against this backdrop, this study adopts new critical and conceptual approaches to interrogate existing narratives, discourse and ideas on/or about female heroism. By focusing on selected epics, this work incorporates perceptions about women in folktales whose themes comment and reflect on the presentation of female characters and the roles they execute in society. The present contribution critically examines the role of supernatural forces in female characters’ commitment and heroism; not only protecting Soundiata, Shaka, and Lianja in accomplishing their destinies but also showcasing the activities, traditions, belief systems and culture of the Mandingo, Zulu, and Mongo in their respective societies.

2011-01-01

The High Voltage Converter Modulators (HVCM) for the 100-MeV accelerator was installed to drive the 20-MeV linac. There are two klystrons in the 20-MeV linac and one modulator was used to drive two klystrons simultaneously. The HVCM for the 20-MeV linac area in Korea Atomic Energy Research Institute (KAERI) is shown in Fig. 1. We were faced with the necessity of integrating Programmable Logic Controllers (PLCs) for the HVCM into the Proton Engineering Frontier Project (PEFP) control system. At the PEFP, Experimental Physics and Industrial Control System (EPICS) has become the most widely used solution for building control systems for 100MeV proton accelerator. The EPICS as a standard development tool is a distributed architecture that provides several solutions such as independent programming tools for operating system, operator interface tools, and archiving tools. Although EPICS is used directly in our control system, HVCMs were delivered with the Allen-Bradley ControlLogix as a PLC. The industrial PLC has been verified for safety systems. We need to connect an interface from our EPICS control system to AB-PLC using Ethernet/IP (ControlNet over Ethernet) protocol over Ethernet. In this paper, we will present the communication protocol and EPICS IOC installation for the EPICS based PLC control system

The Korea multi-purpose accelerator complex (KOMAC) has two beam extraction points at 20 and 100 MeV for proton beam utilization. There are about 70 control systems for controlling the KOMAC subsystems, such as the ion source, the radio frequency, the diagnostic devices, the magnet power supply, and the cooling system. The infrastructure which includes network system, local controllers, and control system environment was required to be changed to process increasing process variables without fail. Experimental Physics and Industrial Control System (EPICS) based high level control environment which includes alarm, data archiving was changed to support the improved infrastructure of KOMAC control system. In this paper, we will describe the improvement of infrastructures for the KOMAC control system and EPICS based high level application. We improved the control network environment and EPCIS based high level application for enhancement of the KOMAC control system.

Integrating Gigabit ethernet cameras into EPICS at Diamond light source

International Nuclear Information System (INIS)

Cobb, T.

2012-01-01

At Diamond Light Source a range of cameras are used to provide images for diagnostic purposes in both the accelerator and photo beamlines. The accelerator and existing beamlines use Point Grey Flea and Flea2 Firewire cameras. We have selected Gigabit Ethernet cameras supporting GigE Vision for our new photon beamlines. GigE Vision is an interface standard for high speed Ethernet cameras which encourages inter-operability between manufacturers. This paper describes the challenges encountered while integrating GigE Vision cameras from a range of vendors into EPICS. GigE Vision cameras appear to be more reliable than the Firewire cameras, and the simple cabling makes much easier to move the cameras to different positions. Upcoming power over Ethernet versions of the cameras will reduce the number of cables still further

To report the 1-year results of a pivotal study for a new-generation nitinol stent for the treatment of iliac atherosclerotic lesions. The ORION trial (ClinicalTrials.gov identifier NCT00896337) was a single-arm, non-randomized, prospective, multicenter clinical trial that enrolled 125 patients (81 men; mean age 61.1±9.3 years) implanted with the EPIC self-expanding nitinol stent system in 166 de novo or restenotic iliac artery lesions ≤13 cm long. The primary endpoint was the 9-month major adverse event rate [i.e., device- or procedure-related death within 30 days, myocardial infarction during the index hospitalization, target vessel revascularization (TVR), or index limb amputation]. Follow-up occurred at hospital discharge and at 1, 9, and 12 months. An independent core laboratory evaluated ultrasound results at 1, 9, and 12 months. The primary endpoint met the prespecified performance goal, with only 3.4% (4/117) of patients experiencing a major adverse event by 9 months (p<0.0001). By 12 months, 6 (5.4%) of 111 patients had TVR; none had an index limb amputation. The ankle-brachial index, Walking Impairment Questionnaire, and Rutherford classifications all showed sustained improvements through 12 months. Primary patency was 94.4% with comparable results for lesions classified as complex (TASC II C/D 95.5%) or non-complex (TASC II A/B 95.0%). The EPIC stent system demonstrated safety and effectiveness through 12 months, including improvements for complex lesions. The EPIC stent is a viable alternative to surgery for patients with either complex or non-complex lesions.

Sazykina, Tatiana; Kryshev, Ivan I

2006-01-01

The paper presents data on radiation effects in populations of wild vertebrate animals inhabiting contaminated terrestrial ecosystems. The data were extracted from the database "Radiation effects on biota", compiled within the framework of the EC Project EPIC (2000-2003). The data collection, based on publications in Russian, demonstrates radiation effects in the areas characterized with high levels of radionuclides (Kyshtym radioactive trace; "spots" of enhanced natural radioactivity in the Komi region of Russia; territories contaminated from the Chernobyl fallout). The data covers a wide range of exposures from acute accidental irradiation to lifetime exposures at relatively low dose rates. Radiation effects include mortality, changes in reproduction, decrease of health, ecological effects, cytogenetic effects, adaptation to radiation, and others. Peculiarities of radiation effects caused by different radionuclides are described, also the severity of effects as they appear in different organisms (e.g. mice, frogs, birds, etc.).

Richards, J.; Nussbaumer, R.; Rapaz, S.; Waters, G.

2012-01-01

The DC linear accelerators of the ISAC radioactive beam facility at TRIUMF do not impose rigorous timing constraints on the control system. Therefore a real-time operating system is not essential for device control. The ISAC Control System is completing a move to the use of the Linux operating system for hosting all EPICS IOCs. The IOC platforms include GE-Fanuc VME based CPUs for control of most optics and diagnostics, rack mounted servers for supervising PLCs, small desktop PCs for GPIB and RS232 instruments, as well as embedded ARM processors controlling CAN-bus devices that provide a suitcase sized control system. This article focuses on the experience of creating a customized Linux distribution for front-end IOC deployment. Rationale, a road-map of the process, and efficiency advantages in personnel training and system management realized by using a single OS will be discussed. (authors)

She became a pionery because written and published the first epic work by a woman in Portuguese language: Memorial da Infância de Christo e Triumpho do Divino Amor (1639. This book is a key work for our understanding of both gender and epic studies, both in the context of Portuguese literature and from the standpoint the greek mythology including in the monasteries. For this we will make a survey around what the critics say about this god and which are the appropriations that the writer-nun gives to this myth in her text because he figures quite often, more than other mythological gods, with clearly intended to demonstrate the symbolic plurality of this deity in the service of what is benevolent and Christian.

Fuel and coolant motions following pin failure: EPIC models and the PBE-5S experiment

International Nuclear Information System (INIS)

Garner, P.L.; Abramson, P.B.

1979-01-01

The EPIC computer code has been used to analyze the post-fuel-pin-failure behavior in the PBE-5S experiment performed at Sandia Laboratories. The effects of modeling uncertainties on the calculation are examined. The calculations indicate that the majority of the piston motion observed in the test is due to the initial pressurization of the coolant channel by fuel vapor at cladding failure. A more definitive analysis requires improvements in calculational capabilities and experiment diagnostics

Versatile Data Acquisition and Controls for EPICS using VME-based FPGAs

International Nuclear Information System (INIS)

Trent Allison; Roger Flood

2001-01-01

Field Programmable Gate Arrays (FPGAs) have provided versatile VME based data acquisition and control systems with minimal development times for the Thomas Jefferson National Accelerator Facility (Jefferson Lab). FPGAs have been used to interface with VME controllers using both standard A16 and A24 address modes. VME vector-interrupt capability has also been implemented for timing issues in some applications. FPGA designs have additionally been used to provide controls for various systems by interfacing with Analog to Digital Converters (DAC), interlocks, and other drive signals. These controls can be molded to the individual needs of each system and can provide operators with indicators and controls in EPICS via a VME interface. This allows the developer to choose components and make specifications that are not available commercially. Jefferson Lab has begun developing standard FPGA libraries that result in quick turnaround times and inexpensive designs. There have been approximately eight VME based FPGA designs implanted in one department at Jefferson Lab and they are becoming more widespread. FPGAs continue to become larger and faster enabling systems to be incorporated on one integrated circuit. Inherently, FPGAs can process data faster than many microprocessors due to the small processing overhead associated with a custom FPGA design. The ability to modify FPGA code enables the developer to easily implement future additions to a system, making the design flexible and expandable.

UTOPIA—User-Friendly Tools for Operating Informatics Applications

Science.gov (United States)

Sinnott, J. R.; Attwood, T. K.

2004-01-01

Bioinformaticians routinely analyse vast amounts of information held both in large remote databases and in flat data files hosted on local machines. The contemporary toolkit available for this purpose consists of an ad hoc collection of data manipulation tools, scripting languages and visualization systems; these must often be combined in complex and bespoke ways, the result frequently being an unwieldy artefact capable of one specific task, which cannot easily be exploited or extended by other practitioners. Owing to the sizes of current databases and the scale of the analyses necessary, routine bioinformatics tasks are often automated, but many still require the unique experience and intuition of human researchers: this requires tools that support real-time interaction with complex datasets. Many existing tools have poor user interfaces and limited real-time performance when applied to realistically large datasets; much of the user's cognitive capacity is therefore focused on controlling the tool rather than on performing the research. The UTOPIA project is addressing some of these issues by building reusable software components that can be combined to make useful applications in the field of bioinformatics. Expertise in the fields of human computer interaction, high-performance rendering, and distributed systems is being guided by bioinformaticians and end-user biologists to create a toolkit that is both architecturally sound from a computing point of view, and directly addresses end-user and application-developer requirements.

Climate risk screening tools and their application: A guide to the guidance

Energy Technology Data Exchange (ETDEWEB)

Traerup, S.; Olhoff, A.

2011-07-01

Climate risk screening is an integral part of efforts to ascertain current and future vulnerabilities and risks related to climate change. It is a prerequisite for identifying and designing adaptation measures, and an important element in the process of integrating, or mainstreaming, climate change adaptation into development project, planning and policy processes. There is an increasing demand and attention among national stakeholders in developing countries to take into account potential implications of climate variability and change for planning and prioritizing of development strategies and activities. Subsequently, there is a need for user friendly guidance on climate risk screening tools and their potentials for application that targets developing country stakeholders. This need is amplified by the sheer volume of climate change mainstreaming guidance documents and risk screening and assessment tools available and currently under development. Against this background, this paper sets out to provide potential users in developing countries, including project and programme developers and managers, with an informational entry point to climate risk screening tools. The emphasis in this report is on providing: 1) An overview of available climate risk screening and assessment tools along with indications of the tools available and relevant for specific purposes and contexts (Section 3). 2) Examples of application of climate risk screening and assessment tools along with links to further information (Section 4). Before turning to the respective sections on available climate risk screening tools and examples of their application, a delimitation of the tools included in this paper is included in Section 2. This section also provides a brief overview of how climate screening and related tools fit into decision making steps at various planning and decision making levels in conjunction with an outline of overall considerations to make when choosing a tool. The paper is

Management tools for distributed control system in KSTAR

2012-01-01

The integrated control system of the Korea Superconducting Tokamak Advanced Research (KSTAR) has been developed with distributed control systems based on Experimental Physics and Industrial Control System (EPICS) middle-ware. It has the essential role of remote operation, supervising of tokamak device and conducting of plasma experiments without any interruption. Therefore, the availability of the control system directly impacts on the entire device performance. For the non-interrupted operation of the KSTAR control system, we have developed a tool named as Control System Monitoring (CSM) to monitor the resources of EPICS Input/Output Controller (IOC) servers (utilization of memory, cpu, disk, network, user-defined process and system-defined process), the soundness of storage systems (storage utilization, storage status), the status of network switches using Simple Network Management Protocol (SNMP), the network connection status of every local control sever using Internet Control Message Protocol (ICMP), and the operation environment of the main control room and the computer room (temperature, humidity, electricity) in real time. When abnormal conditions or faults are detected by the CSM, it alerts abnormal or fault alarms to operators. Especially, if critical fault related to the data storage occurs, the CSM sends the simple messages to operator's mobile phone. The operators then quickly restored the problems according to the emergency procedure. As a result of this process, KSTAR was able to perform continuous operation and experiment without interruption for 4 months

Development of a state machine sequencer for the Keck Interferometer: evolution, development, and lessons learned using a CASE tool approach

Reder, Leonard J.; Booth, Andrew; Hsieh, Jonathan; Summers, Kellee R.

2004-09-01

This paper presents a discussion of the evolution of a sequencer from a simple Experimental Physics and Industrial Control System (EPICS) based sequencer into a complex implementation designed utilizing UML (Unified Modeling Language) methodologies and a Computer Aided Software Engineering (CASE) tool approach. The main purpose of the Interferometer Sequencer (called the IF Sequencer) is to provide overall control of the Keck Interferometer to enable science operations to be carried out by a single operator (and/or observer). The interferometer links the two 10m telescopes of the W. M. Keck Observatory at Mauna Kea, Hawaii. The IF Sequencer is a high-level, multi-threaded, Harel finite state machine software program designed to orchestrate several lower-level hardware and software hard real-time subsystems that must perform their work in a specific and sequential order. The sequencing need not be done in hard real-time. Each state machine thread commands either a high-speed real-time multiple mode embedded controller via CORBA, or slower controllers via EPICS Channel Access interfaces. The overall operation of the system is simplified by the automation. The UML is discussed and our use of it to implement the sequencer is presented. The decision to use the Rhapsody product as our CASE tool is explained and reflected upon. Most importantly, a section on lessons learned is presented and the difficulty of integrating CASE tool automatically generated C++ code into a large control system consisting of multiple infrastructures is presented.

Full Text Available Supplement users (SU make healthy lifestyle choices; on the other hand, SU report more medical conditions. We hypothesised that cod liver oil (CLO consumers are similar to non-supplement users, since CLO use might originate from historical motives, i.e., rickets prevention, and not health consciousness. CLO consumers were studied in order to identify possible confounders, such as confounding by indication. The European Prospective Investigation into Cancer (EPIC investigates causes of chronic disease. The participants were 25,639 men and women, aged 40–79 years, recruited from general practices in Norfolk, East-Anglia (UK. Participants completed questionnaires and a health examination between 1993 and 1998. Supplement use was measured using 7-day diet diaries. CLO was the most common supplement used, more prevalent among women and associated with not smoking, higher physical activity level and more favourable eating habits. SU had a higher occurrence of benign growths and bone-related diseases, but CLO was negatively associated with cardiovascular-related conditions. Although the results of SU characteristics in EPIC-Norfolk are comparable with studies worldwide, the CLO group is different from SU in general. Confounding by indication takes place and will need to be taken into account when analysing prospective associations of CLO use with fracture risk and cardiovascular diseases.

International Nuclear Information System (INIS)

Bass, B.R.; Kruse, K.; Dodds, R.H. Jr.; Malik, S.N.M.

1998-11-01

The Habanero software was developed by the National Center for Superconducting Applications at the University of Illinois, Urbana-Champaign, as a framework for the collaborative sharing of Java applications. The Habanero tool performs distributed communication of single-user, computer software interactions to a multiuser collaborative environment. An investigation was conducted to evaluate the capabilities of the Habanero tool in providing an Internet-based collaborative framework for researchers located at different sites and operating on different workstations. These collaborative sessions focused on the sharing of test data and analysis results from materials engineering areas (i.e., fracture mechanics and structural integrity evaluations) related to reactor pressure vessel safety research sponsored by the US Nuclear Regulatory Commission. This report defines collaborative-system requirements for engineering applications and provides an overview of collaborative systems within the project. The installation, application, and detailed evaluation of the performance of the Habanero collaborative tool are compared to those of another commercially available collaborative product. Recommendations are given for future work in collaborative communications

Full Text Available Background: Beaker is a relatively new laboratory information system (LIS offered by Epic Systems Corporation as part of its suite of health-care software and bundled with its electronic medical record, EpicCare. It is divided into two modules, Beaker anatomic pathology (Beaker AP and Beaker Clinical Pathology. In this report, we describe our experience implementing Beaker AP version 2014 at an academic medical center with a go-live date of October 2015. Methods: This report covers preimplementation preparations and challenges beginning in September 2014, issues discovered soon after go-live in October 2015, and some post go-live optimizations using data from meetings, debriefings, and the project closure document. Results: We share specific issues that we encountered during implementation, including difficulties with the proposed frozen section workflow, developing a shared specimen source dictionary, and implementation of the standard Beaker workflow in large institution with trainees. We share specific strategies that we used to overcome these issues for a successful Beaker AP implementation. Several areas of the laboratory-required adaptation of the default Beaker build parameters to meet the needs of the workflow in a busy academic medical center. In a few areas, our laboratory was unable to use the Beaker functionality to support our workflow, and we have continued to use paper or have altered our workflow. In spite of several difficulties that required creative solutions before go-live, the implementation has been successful based on satisfaction surveys completed by pathologists and others who use the software. However, optimization of Beaker workflows has continued to be an ongoing process after go-live to the present time. Conclusions: The Beaker AP LIS can be successfully implemented at an academic medical center but requires significant forethought, creative adaptation, and continued shared management of the ongoing product by

Many older adults rely on a manual wheelchair for mobility but typically receive little, if any, training on how to use their wheelchair effectively and independently. Standardized skill training is an effective intervention, but limited access to clinician trainers is a substantive barrier. Enhancing Participation in the Community by Improving Wheelchair Skills (EPIC Wheels) is a 1-month monitored home training program for improving mobility skills in older novice manual wheelchair users, integrating principles from andragogy and social cognitive theory. The purpose of this study is to determine whether feasibility indicators and primary clinical outcome measures of the EPIC Wheels program are sufficiently robust to justify conducting a subsequent multi-site randomized controlled trial. A 2 × 2 factorial randomized controlled trial at two sites will compare improvement in wheelchair mobility skills between an EPIC Wheels treatment group and a computer-game control group, with additional wheelchair use introduced as a second factor. A total of 40 community-dwelling manual wheelchair users at least 55 years old and living in two Canadian metropolitan cities (n = 20 × 2) will be recruited. Feasibility indicators related to study process, resources, management, and treatment issues will be collected during data collection and at the end of the study period, and evaluated against proposed criteria. Clinical outcome measures will be collected at baseline (pre-randomization) and post-intervention. The primary clinical outcome measure is wheelchair skill capacity, as determined by the Wheelchair Skills Test, version 4.1. Secondary clinical outcome measures include wheelchair skill safety, satisfaction with performance, wheelchair confidence, life-space mobility, divided-attention, and health-related quality of life. The EPIC Wheels training program offers several innovative features. The convenient, portable, economical, and adaptable tablet-based, home program model

Nowadays the decision makers but also citizens are concerning with the sustainability and vulnerability of land management practices on various aspects and in particular on water quality and quantity in complex watersheds. The Black Sea Catchment is an important watershed in the Central and East Europe. In the FP7 project enviroGRIDS [1] was developed a Web Portal that incorporates different tools and applications focused on geospatial data management, hydrologic model calibration, execution and visualization and training activities. This presentation highlights, from the end-user point of view, the scenario related with hydrological models using the tools and applications available in the enviroGRIDS Web Portal [2]. The development of SWAT (Soil Water Assessment Tool) hydrological models is a well known procedure for the hydrological specialists [3]. Starting from the primary data (information related to weather, soil properties, topography, vegetation, and land management practices of the particular watershed) that are used to develop SWAT hydrological models, to specific reports, about the water quality in the studied watershed, the hydrological specialist will use different applications available in the enviroGRIDS portal. The tools and applications available through the enviroGRIDS portal are not dealing with the building up of the SWAT hydrological models. They are mainly focused on: calibration procedure (gSWAT [4]) - uses the GRID computational infrastructure to speed-up the calibration process; development of specific scenarios (BASHYT [5]) - starts from an already calibrated SWAT hydrological model and defines new scenarios; execution of scenarios (gSWATSim [6]) - executes the scenarios exported from BASHYT; visualization (BASHYT) - displays charts, tables and maps. Each application is built-up as a stack of functional layers. We combine different layers of applications by vertical interoperability in order to build the desired complex functionality. On

Continuous improvement of product and process quality is always challenging and creative task in today's era of globalization. Various quality tools are available and used for the same. Some of them are successful and few of them are not. Considering the complexity in the continuous quality improvement (CQI) process various new techniques are being introduced by the industries, as well as proposed by researchers and academia. Lean Manufacturing, Six Sigma, Lean Six Sigma is some of the techniques. In recent years, there are new tools being opted by the industry, especially automotive, called as Automotive Core Tools (ACT). The intention of this paper is to review the applications and benefits along with existing research on Automotive Core Tools with special emphasis on continuous quality improvement. The methodology uses an extensive review of literature through reputed publications—journals, conference proceedings, research thesis, etc. This paper provides an overview of ACT, its enablers, and exertions, how it evolved into sophisticated methodologies and benefits used in organisations. It should be of value to practitioners of Automotive Core Tools and to academics who are interested in how CQI can be achieved using ACT. It needs to be stressed here that this paper is not intended to scorn Automotive Core Tools, rather, its purpose is limited only to provide a balance on the prevailing positive views toward ACT.

Highlights: • The test bed allows for the validation of real-time image processing techniques. • Offers FPGA (FlexRIO) image processing that does not require CPU intervention. • Is fully compatible with the architecture of the ITER Fast Controllers. • Provides flexibility and easy integration in distributed experiments based on EPICS. - Abstract: Image diagnostics are becoming standard ones in nuclear fusion. At present, images are typically analyzed off-line. However, real-time processing is occasionally required (for instance, hot-spot detection or pattern recognition tasks), which will be the objective for the next generation of fusion devices. In this paper, a test bed for image generation, acquisition, and real-time processing is presented. The proposed solution is built using a Camera Link simulator, a Camera Link frame-grabber, a PXIe chassis, and offers software interface with EPICS. The Camera Link simulator (PCIe card PCIe8 DVa C-Link from Engineering Design Team) generates simulated image data (for example, from video-movies stored in fusion databases) using a Camera Link interface to mimic the frame sequences produced with diagnostic cameras. The Camera Link frame-grabber (FlexRIO Solution from National Instruments) includes a field programmable gate array (FPGA) for image acquisition using a Camera Link interface; the FPGA allows for the codification of ad-hoc image processing algorithms using LabVIEW/FPGA software. The frame grabber is integrated in a PXIe chassis with system architecture similar to that of the ITER Fast Controllers, and the frame grabber provides a software interface with EPICS to program all of its functionalities, capture the images, and perform the required image processing. The use of these four elements allows for the implementation of a test bed system that permits the development and validation of real-time image processing techniques in an architecture that is fully compatible with that of the ITER Fast Controllers

Full Text Available Carbon sequestration in soils constitutes an important option that can be used to reduce CO2 emissions to the atmosphere and reduce environmental impacts. Soil organic carbon (SOC is both a source of carbon release and a sink for carbon sequestration. Our objectives in this study were to validate the interactive Environmental Policy Impact Calculator (i-EPIC model version 0509, as well as to estimate SOC sequestration under climate change scenarios A2 and B2 SRES emission scenarios in Thailand. The SOC estimated by i-EPIC was compared with data from the Office of Soil Resources Survey and Research, Land Development Department. The results indicated that performance testing of i-EPIC is able to estimate SOC. Validation of SOC proved to be satisfactory with a resulting root mean square error (RMSE % value of 34.60. The SOC content showed a decreasing trend under B2 and A2 climate scenarios (average 0.87% and 0.85%, respectively compared to the reference from 2007 (average 0.92%. Stepwise regression analysis also revealed that carbon from residue decomposition, biomass pool carbon, and the total change of the carbon pool were directly correlated with the SOC (R2= 0.99, p< 0.01. Furthermore, the change from rain supplied water to irrigation also resulted in an increase of carbon inputs but a decrease in the SOC sequestered during the 2007-2017 period. Regression analyses indicated that soil carbon sequestration responds linearly to carbon input. Significant changes in carbon input as well as decreases in SOC levels were observed as temperature and precipitation increased. Based on the testing and analysis, we concluded that i-EPIC is capable of reliably simulating effects of climate change on SOC sequestration. Based on the results, this knowledge and information can increase effectiveness in the promotion of integrated rice management for rice production in Thailand.

Full Text Available Organic bioelectronics forms the basis of conductive polymer tools with great potential for application in biomedical science and medicine. It is a rapidly growing field of both academic and industrial interest since conductive polymers bridge the gap between electronics and biology by being electronically and ionically conductive. This feature can be employed in numerous ways by choosing the right polyelectrolyte system and tuning its properties towards the intended application. This review highlights how active organic bioelectronic surfaces can be used to control cell attachment and release as well as to trigger cell signaling by means of electrical, chemical or mechanical actuation. Furthermore, we report on the unique properties of conductive polymers that make them outstanding materials for labeled or label-free biosensors. Techniques for electronically controlled ion transport in organic bioelectronic devices are introduced, and examples are provided to illustrate their use in self-regulated medical devices. Organic bioelectronics have great potential to become a primary platform in future bioelectronics. We therefore introduce current applications that will aid in the development of advanced in vitro systems for biomedical science and of automated systems for applications in neuroscience, cell biology and infection biology. Considering this broad spectrum of applications, organic bioelectronics could lead to timely detection of disease, and facilitate the use of remote and personalized medicine. As such, organic bioelectronics might contribute to efficient healthcare and reduced hospitalization times for patients.

Full Text Available Whether and how n-3 and n-6 polyunsaturated fatty acids (PUFAs are related to type 2 diabetes (T2D is debated. Objectively measured plasma PUFAs can help to clarify these associations.Plasma phospholipid PUFAs were measured by gas chromatography among 12,132 incident T2D cases and 15,919 subcohort participants in the European Prospective Investigation into Cancer and Nutrition (EPIC-InterAct study across eight European countries. Country-specific hazard ratios (HRs were estimated using Prentice-weighted Cox regression and pooled by random-effects meta-analysis. We also systematically reviewed published prospective studies on circulating PUFAs and T2D risk and pooled the quantitative evidence for comparison with results from EPIC-InterAct. In EPIC-InterAct, among long-chain n-3 PUFAs, α-linolenic acid (ALA was inversely associated with T2D (HR per standard deviation [SD] 0.93; 95% CI 0.88-0.98, but eicosapentaenoic acid (EPA and docosahexaenoic acid (DHA were not significantly associated. Among n-6 PUFAs, linoleic acid (LA (0.80; 95% CI 0.77-0.83 and eicosadienoic acid (EDA (0.89; 95% CI 0.85-0.94 were inversely related, and arachidonic acid (AA was not significantly associated, while significant positive associations were observed with γ-linolenic acid (GLA, dihomo-GLA, docosatetraenoic acid (DTA, and docosapentaenoic acid (n6-DPA, with HRs between 1.13 to 1.46 per SD. These findings from EPIC-InterAct were broadly similar to comparative findings from summary estimates from up to nine studies including between 71 to 2,499 T2D cases. Limitations included potential residual confounding and the inability to distinguish between dietary and metabolic influences on plasma phospholipid PUFAs.These large-scale findings suggest an important inverse association of circulating plant-origin n-3 PUFA (ALA but no convincing association of marine-derived n3 PUFAs (EPA and DHA with T2D. Moreover, they highlight that the most abundant n6-PUFA (LA is inversely

To test the feasibility of tools and procedures for a pan-European food consumption survey among children 0-10 years and to recommend one of two tested dietary assessment methods. Two pilot studies including 378 children were conducted in Belgium and the Czech Republic in the Pilot studies for Assessment of Nutrient intake and food Consumption among Kids in Europe. One protocol included a 3-day food diary which was checked with a parent, and data were entered afterwards using EPIC-Soft. The alternative protocol consisted of two non-consecutive 1-day food diaries followed by EPIC-Soft completion interviews. Both protocols included general and food propensity questionnaires and anthropometric measurements. The protocols were compared using evaluation questionnaires among the participating parents and study personnel. The parents found the questionnaires and instructions for filling in the food diaries understandable. Food description and food quantification was evaluated as problematic by 29 and 15% of the participants for the 3-day diaries versus 15 and 12% for the 1-day diaries. The protocol with 1-day food diaries was evaluated as less burdensome by the parents and logistically more challenging by the interviewers. Both dietary assessment methods with related tools and administration protocols were evaluated as feasible. The administration protocol with two 1-day food diaries with completion interviews offers more advantages for the future pan-European survey in children 0-10 years. The positive evaluation of feasibility of tools and materials is an important step towards harmonised food consumption data at European level among the younger age groups.

Remote tooling applications at the FFTF/IEM cell

At the fast flux test facility, a US Government-owned 400-MW(thermal) sodium-cooled fast reactor, the interim examination and maintenance (IEM) cell is used for the remote disassembly of irradiated fuel and material experiments and remote maintenance operations. The IEM cell has been a challenging area both for maintenance and operation of remote equipment. Innovative tooling has been required to provide the reliability, strength and dexterity for performing myriad bolting, cutting, gripping, and other such functions. Over the years, a set of basic components that can be modified and adapted to several applications has been developed. These include torque multipliers, torque limiters, right-angle drives, and many common hand tools with fittings designed to be handled by master-slave manipulators (MSM) or electromechanical manipulator (EMM) hands. An example of such a system is the closed loop ex-vessel machine (CLEM) grapple change tool, which is designed for both hands-on use in a glove box and remote use in the IEM cell

Few epidemiological studies have examined the association between dietary trans fatty acids and weight gain, and the evidence remains inconsistent. The main objective of the study was to investigate the prospective association between biomarker of industrial trans fatty acids and change in weight within the large study European Prospective Investigation into Cancer and Nutrition (EPIC) cohort. Baseline plasma fatty acid concentrations were determined in a representative EPIC sample from the 23 participating EPIC centers. A total of 1,945 individuals were followed for a median of 4.9 years to monitor weight change. The association between elaidic acid level and percent change of weight was investigated using a multinomial logistic regression model, adjusted by length of follow-up, age, energy, alcohol, smoking status, physical activity, and region. In women, doubling elaidic acid was associated with a decreased risk of weight loss (odds ratio (OR) = 0.69, 95% confidence interval (CI) = 0.55-0.88, p = 0.002) and a trend was observed with an increased risk of weight gain during the 5-year follow-up (OR = 1.23, 95% CI = 0.97-1.56, p = 0.082) (p-trendacid level and risk of weight loss (OR = 0.82, 95% CI = 0.66-1.01, p = 0.062) while no significant association was found with risk of weight gain during the 5-year follow-up (OR = 1.08, 95% CI = 0.88-1.33, p = 0.454). No association was found for saturated and cis-monounsaturated fatty acids. These data suggest that a high intake of industrial trans fatty acids may decrease the risk of weight loss, particularly in women. Prevention of obesity should consider limiting the consumption of highly processed foods, the main source of industrially-produced trans fatty acids.

We have discovered a new, rare triple-mode RR Lyr star, EPIC 201585823, in the Kepler K2 mission Campaign 1 data. This star pulsates primarily in the fundamental and first-overtone radial modes, and, in addition, a third non-radial mode. The ratio of the period of the non-radial mode...... pixels with significant signal for the star, but without correction for pointing changes, is best for frequency analysis of this star, and, by implication, other RR Lyr stars observed by the K2 mission. We compare several pipeline reductions of the K2 mission data for this star....

Calvo, J.; Ibarra, A.; Miguel Angel Patricio; Rivers, M.

2012-01-01

The IFMIF-EVEDA (International Fusion Materials Irradiation Facility - Engineering Validation and Engineering Design Activity) linear accelerator will be a 9 MeV, 125 mA CW (Continuous Wave) deuteron accelerator prototype to validate the technical options of the accelerator design for IFMIF. The primary mission of such facility is to test and verify materials performance when subjected to extensive neutron irradiation of the type encountered in a fusion reactor. The RF (Radio Frequency) power system of IFMIF-EVEDA consists of 18 RF chains working at 175 MHz with three amplification stages each. The LLRF (Low-Level Radio Frequency) controls the amplitude and phase of the signal to be synchronized with the beam and it also controls the resonance frequency of the cavities. The system is based on a commercial cPCI (Compact Peripheral Component Interconnect) FPGA (Field Programmable Gate Array) board provided by Lyrtech and controlled by a Windows Host PC. For this purpose, it is mandatory to communicate the cPCI FPGA Board with an EPICS Channel Access, building an IOC (Input Output Controller). A new software architecture to design a device support, using AsynPortDriver class and CSS as a GUI (Graphical User Interface), is also presented. (authors)

This report, deliverable D2.1 in the CRISP project, serves as a preparation report for the development of simulation tools and prototype software which will be developed in forthcoming stages of the CRISP project. Application areas for these simulations are: fault detection and diagnosis, supply and demand matching and intelligent load shedding. The context in which these applications function is the power network with a high degree of distributed generation, including renewables. In order to control a so called distributed grid we can benefit from a high level of distributed control and intelligence. This requires, on top of the power system network, an information and communication network.. We argue that such a network should be seen as an enabler of distributed control and intelligence. The applications, through which control and intelligence is implemented, then form a third network layer, the service oriented network. Building upon this three-layered network model we derive in this report the requirements for a simulation tool and experiments which study new techniques for fault detection and diagnostics and for simulation tools and experiments implementing intelligent load shedding and supply and demand matching scenarios. We also look at future implementation of these services within the three-layered network model and the requirements that follow for the core information and communication network and for the service oriented network. These requirements, supported by the studies performed in the CRISP Workpackage 1, serve as a basis for development of the simulation tools in the tasks 2.2 to 2.4.

The U.S. Nuclear Regulatory Commission's (NRC) conducts human factors engineering (HFE) safety reviews of applicant submittals for new plants and for changes to existing plants. The reviews include the evaluation of the methods and tools (M&T) used by applicants as part of their HFE program. The technology used to perform HFE activities has been rapidly evolving, resulting in a whole new generation of HFE M&Ts. The objectives of this research were to identify the current trends in HFE methods and tools, determine their applicability to NRC safety reviews, and identify topics for which the NRC may need additional guidance to support the NRC's safety reviews. We conducted a survey that identified over 100 new HFE M&Ts. The M&Ts were assessed to identify general trends. Seven trends were identified: Computer Applications for Performing Traditional Analyses, Computer-Aided Design, Integration of HFE Methods and Tools, Rapid Development Engineering, Analysis of Cognitive Tasks, Use of Virtual Environments and Visualizations, and Application of Human Performance Models. We assessed each trend to determine its applicability to the NRC's review by considering (1) whether the nuclear industry is making use of M&Ts for each trend, and (2) whether M&Ts reflecting the trend can be reviewed using the current design review guidance. We concluded that M&T trends that are applicable to the commercial nuclear industry and are expected to impact safety reviews may be considered for review guidance development. Three trends fell into this category: Analysis of Cognitive Tasks, Use of Virtual Environments and Visualizations, and Application of Human Performance Models. The other trends do not need to be addressed at this time.

To support the development of in-service inspection methods for the Advanced Sodium Test Reactor for Industrial Demonstration (ASTRID) project led by the French Atomic Energy Commission (CEA), several tools that allow situations specific to Sodium cooled Fast Reactors (SFR) to be modeled have been implemented in the CIVA software and exploited. This paper details specific applications and results obtained. For instance, a new specular reflection model allows the calculation of complex echoes from scattering structures inside the reactor vessel. EMAT transducer simulation models have been implemented to develop new transducers for sodium visualization and imaging. Guided wave analysis tools have been developed to permit defect detection in the vessel shell. Application examples and comparisons with experimental data are presented.

Safety control system and its interface to EPICS for the off-line front end of the SPES project

International Nuclear Information System (INIS)

Vasquez, J.; Andrighetto, A.; Bassato, G.; Costa, L.; Giacchini, M.; Bertocco, M.

2012-01-01

The SPES (Selective Production of Exotic Species) project is based on a facility for the production of neutron-rich radioactive ion beams using the isotope separation on-line technique. The SPES off-line front-end apparatus involves a number of subsystems and procedures that are potentially dangerous both for human operators and for the equipment. The high voltage power supply, the ion source complex power supplies, the target chamber handling systems and the laser source are some example of these subsystems. For that reason, a safety control system has been developed. It is based on Schneider Electrics Preventa family safety modules that control the power supply of critical subsystems in combination with safety detectors that monitor critical variables. A Programmable Logic Controller (PLC), model BMXP342020 from the Schneider Electrics Modicon M340 family, is used for monitoring the status of the system as well as controlling the sequence of some operations in automatic way. A touch screen, model XBTGT5330 from the Schneider Electrics Magelis family, is used as Human Machine Interface (HMI) and communicates with the PLC using MODBUS-TCP. Additionally, an interface to the EPICS control network was developed using a home-made MODBUS-TCP EPICS driver in order to integrate it to the control system of the Front End as well as present the status of the system to the users on the main control panel.

The Experimental Physics Industrial Control System (EPICS) is a set of software which is being used as the basis of the National Spherical Torus Experiment's (NSTX) Process Control System, a major element of the NSTX's Central Instrumentation and Control System. EPICS is a result of a co-development effort started by several US Department of Energy National Laboratories. EPICS is actively supported through an international collaboration made up of government and industrial users. EPICS' good points include portability, scalability, and extensibility. A drawback for small experiments is that a wide range of software skills are necessary to get the software tools running for the process engineers. The authors' experience in designing, developing, operating, and maintaining NSTX's EPICS (system) will be reviewed

Nuclear Tools For Oilfield Logging-While-Drilling Applications

International Nuclear Information System (INIS)

Reijonen, Jani

2011-01-01

Schlumberger is an international oilfield service company with nearly 80,000 employees of 140 nationalities, operating globally in 80 countries. As a market leader in oilfield services, Schlumberger has developed a suite of technologies to assess the downhole environment, including, among others, electromagnetic, seismic, chemical, and nuclear measurements. In the past 10 years there has been a radical shift in the oilfield service industry from traditional wireline measurements to logging-while-drilling (LWD) analysis. For LWD measurements, the analysis is performed and the instruments are operated while the borehole is being drilled. The high temperature, high shock, and extreme vibration environment of LWD imposes stringent requirements for the devices used in these applications. This has a significant impact on the design of the components and subcomponents of a downhole tool. Another significant change in the past few years for nuclear-based oilwell logging tools is the desire to replace the sealed radioisotope sources with active, electronic ones. These active radiation sources provide great benefits compared to the isotopic sources, ranging from handling and safety to nonproliferation and well contamination issues. The challenge is to develop electronic generators that have a high degree of reliability for the entire lifetime of a downhole tool. LWD tool testing and operations are highlighted with particular emphasis on electronic radiation sources and nuclear detectors for the downhole environment.

Ratsnake: A Versatile Image Annotation Tool with Application to Computer-Aided Diagnosis

Directory of Open Access Journals (Sweden)

D. K. Iakovidis

2014-01-01

Full Text Available Image segmentation and annotation are key components of image-based medical computer-aided diagnosis (CAD systems. In this paper we present Ratsnake, a publicly available generic image annotation tool providing annotation efficiency, semantic awareness, versatility, and extensibility, features that can be exploited to transform it into an effective CAD system. In order to demonstrate this unique capability, we present its novel application for the evaluation and quantification of salient objects and structures of interest in kidney biopsy images. Accurate annotation identifying and quantifying such structures in microscopy images can provide an estimation of pathogenesis in obstructive nephropathy, which is a rather common disease with severe implication in children and infants. However a tool for detecting and quantifying the disease is not yet available. A machine learning-based approach, which utilizes prior domain knowledge and textural image features, is considered for the generation of an image force field customizing the presented tool for automatic evaluation of kidney biopsy images. The experimental evaluation of the proposed application of Ratsnake demonstrates its efficiency and effectiveness and promises its wide applicability across a variety of medical imaging domains.

Rohrmann, S; Kroke, A; Boeing, H; Becker, N

2003-08-01

Smoking prevention is less advanced in Germany compared with other European and North American countries, and fewer data exist, especially on the consumption habits at the individual level over time. EPIC Germany, which is part of a European multicentre study on diet and cancer, collected data on individual smoking behaviour and allows for consideration of the changing consumption pattern for both centres and different age groups. Within EPIC 25 546 and 27 548 participants, respectively, were recruited in Heidelberg and Potsdam. Data on smoking habits were collected by means of a computer-guided interview during the baseline examination between 1994 and 1998. For each birth cohort smoking prevalence and mean number of cigarettes smoked per day at different ages were calculated. Additionally, the prevalence of non-filter cigarette smoking was computed. Smoking prevalence in the 1990s was still higher among men (Heidelberg 16.3-32.3%; Potsdam 18.2-29.3%) than among women (Heidelberg 12.8-32.0%; Potsdam 10.4-27.8%). However, the percentage of women smokers was still increasing. Filter cigarettes comprised a growing percentage of the cigarettes smoked, but especially among men differences between both German cohorts can still be seen: depending on age, 10.0-12.7% of men in the Heidelberg cohort smoked non-filter cigarettes, but only 1.1-2.3% in the Potsdam cohort. The quantity smoked was higher in the Heidelberg than in the Potsdam cohort with respect to the mean number of cigarettes smoked per day as well as the pack-years of smoking. In conclusion, smoking habits in the Potsdam and the Heidelberg cohorts did not strongly differ by smoking prevalence. However, they did differ according to the quantity and quality of smoking. These differences, as well as the changes over the last 40 years may contribute to a changing pattern of diseases in different groups of the German population.

The application of a multi-physics tool kit to spatial reactor dynamics

International Nuclear Information System (INIS)

Clifford, I.; Jasak, H.

2009-01-01

Traditionally coupled field nuclear reactor analysis has been carried out using several loosely coupled solvers, each having been developed independently from the others. In the field of multi-physics, the current generation of object-oriented tool kits provides robust close coupling of multiple fields on a single framework. This paper describes the initial results obtained as part of continuing research in the use of the OpenFOAM multi-physics tool kit for reactor dynamics application development. An unstructured, three-dimensional, time-dependent multi-group diffusion code Diffusion FOAM has been developed using the OpenFOAM multi-physics tool kit as a basis. The code is based on the finite-volume methodology and uses a newly developed block-coupled sparse matrix solver for the coupled solution of the multi-group diffusion equations. A description of this code is given with particular emphasis on the newly developed block-coupled solver, along with a selection of results obtained thus far. The code has performed well, indicating that the OpenFOAM tool kit is suited to reactor dynamics applications. This work has shown that the neutronics and simplified thermal-hydraulics of a reactor May be represented and solved for using a common calculation platform, and opens up the possibility for research into robust close-coupling of neutron diffusion and thermal-fluid calculations. This work has further opened up the possibility for research in a number of other areas, including research into three-dimensional unstructured meshes for reactor dynamics applications. (authors)

Big data is prevalent in HPC computing. Many HPC projects rely on complex workflows to analyze terabytes or petabytes of data. These workflows often require running over thousands of CPU cores and performing simultaneous data accesses, data movements, and computation. It is challenging to analyze the performance involving terabytes or petabytes of workflow data or measurement data of the executions, from complex workflows over a large number of nodes and multiple parallel task executions. To help identify performance bottlenecks or debug the performance issues in large-scale scientific applications and scientific clusters, we have developed a performance analysis framework, using state-ofthe- art open-source big data processing tools. Our tool can ingest system logs and application performance measurements to extract key performance features, and apply the most sophisticated statistical tools and data mining methods on the performance data. It utilizes an efficient data processing engine to allow users to interactively analyze a large amount of different types of logs and measurements. To illustrate the functionality of the big data analysis framework, we conduct case studies on the workflows from an astronomy project known as the Palomar Transient Factory (PTF) and the job logs from the genome analysis scientific cluster. Our study processed many terabytes of system logs and application performance measurements collected on the HPC systems at NERSC. The implementation of our tool is generic enough to be used for analyzing the performance of other HPC systems and Big Data workows.

The SAFRAN tool (Safety Assessment Framework) is a user-friendly software application that incorporates the methodologies developed in the SADRWMS (Safety Assessment Driven Radioactive Waste Management Solutions) project. The International Atomic Energy Agency (IAEA) organized the International Project on Safety Assessment Driving Radioactive Waste Management Solutions (SADRWMS) to examine international approaches to safety assessment for predisposal management of all types of radioactive waste, including disused sources, small volumes, legacy and decommissioning waste, operational waste, and large volume naturally occurring radioactive material residues. SAFRAN provides aid in: Describing the predisposal RW management activities in a systematic way, Conducting the SA (safety assessment) with clear documentation of the methodology, assumptions, input data and models, Establishing a traceable and transparent record of the safety basis for decisions on the proposed RW management solutions, Demonstrating clear consideration of and compliance with national and international safety standards and recommendations. The SAFRAN tool allows the user to visibly, systematically and logically address predisposal radioactive waste management and decommissioning challenges in a structured way. It also records the decisions taken in such a way that it constitutes a justifiable safety assessment of the proposed management solutions. The objective of this paper is to describe the SAFRAN architecture and features, properly define the terms safety case and safety assessment, and to predict the future development of the SAFRAN tool and assess its applicability to the construction of a future LILW (Low and Intermediate Level Waste) storage facility and repository in Croatia, taking into account all the capabilities and modelling features of the SAFRAN tool.

The United States National Science Foundation funded PermaData project led by the National Snow and Ice Data Center (NSIDC) with a team from the Global Terrestrial Network for Permafrost (GTN-P) aimed to improve permafrost data access and discovery. We developed a Data Integration Tool (DIT) to significantly speed up the time of manual processing needed to translate inconsistent, scattered historical permafrost data into files ready to ingest directly into the GTN-P. We leverage this data to support science research and policy decisions. DIT is a workflow manager that divides data preparation and analysis into a series of steps or operations called widgets. Each widget does a specific operation, such as read, multiply by a constant, sort, plot, and write data. DIT allows the user to select and order the widgets as desired to meet their specific needs. Originally it was written to capture a scientist's personal, iterative, data manipulation and quality control process of visually and programmatically iterating through inconsistent input data, examining it to find problems, adding operations to address the problems, and rerunning until the data could be translated into the GTN-P standard format. Iterative development of this tool led to a Fortran/Python hybrid then, with consideration of users, licensing, version control, packaging, and workflow, to a publically available, robust, usable application. Transitioning to Python allowed the use of open source frameworks for the workflow core and integration with a javascript graphical workflow interface. DIT is targeted to automatically handle 90% of the data processing for field scientists, modelers, and non-discipline scientists. It is available as an open source tool in GitHub packaged for a subset of Mac, Windows, and UNIX systems as a desktop application with a graphical workflow manager. DIT was used to completely translate one dataset (133 sites) that was successfully added to GTN-P, nearly translate three datasets

CMS Partial Releases Model, Tools, and Applications. Online and Framework-Light Releases

The CMS Software project CMSSW embraces more than a thousand packages organized in subsystems for analysis, event display, reconstruction, simulation, detector description, data formats, framework, utilities and tools. The release integration process is highly automated by using tools developed or adopted by CMS. Packaging in rpm format is a built-in step in the software build process. For several well-defined applications it is highly desirable to have only a subset of the CMSSW full package bundle. For example, High Level Trigger algorithms that run on the Online farm, and need to be rebuilt in a special way, require no simulation, event display, or analysis packages. Physics analysis applications in Root environment require only a few core libraries and the description of CMS specific data formats. We present a model of CMS Partial Releases, used for preparation of the customized CMS software builds, including description of the tools used, the implementation, and how we deal with technical challenges, suc...

Transportable Applications Environment (TAE) Plus - A NASA productivity tool used to develop graphical user interfaces

Science.gov (United States)

Szczur, Martha R.

1991-01-01

The Transportable Applications Environment (TAE) Plus, developed at NASA's Goddard Space Flight Center, is an advanced portable user interface development environment which simplifies the process of creating and managing complex application graphical user interfaces (GUIs), supports prototyping, allows applications to be oported easily between different platforms, and encourages appropriate levels of user interface consistency between applications. This paper discusses the capabilities of the TAE Plus tool, and how it makes the job of designing and developing GUIs easier for the application developers. The paper also explains how tools like TAE Plus provide for reusability and ensure reliability of UI software components, as well as how they aid in the reduction of development and maintenance costs.

A portable accelerator control toolkit

Energy Technology Data Exchange (ETDEWEB)

Watson, W.A. III

1997-06-01

In recent years, the expense of creating good control software has led to a number of collaborative efforts among laboratories to share this cost. The EPICS collaboration is a particularly successful example of this trend. More recently another collaborative effort has addressed the need for sophisticated high level software, including model driven accelerator controls. This work builds upon the CDEV (Common DEVice) software framework, which provides a generic abstraction of a control system, and maps that abstraction onto a number of site-specific control systems including EPICS, the SLAC control system, CERN/PS and others. In principle, it is now possible to create portable accelerator control applications which have no knowledge of the underlying and site-specific control system. Applications based on CDEV now provide a growing suite of tools for accelerator operations, including general purpose displays, an on-line accelerator model, beamline steering, machine status displays incorporating both hardware and model information (such as beam positions overlaid with beta functions) and more. A survey of CDEV compatible portable applications will be presented, as well as plans for future development.

2016-01-01

The application of surface topography measurement methods to the field of firearm and toolmark analysis is fairly new. The field has been boosted by the development of a number of competing optical methods, which has improved the speed and accuracy of surface topography acquisitions. We describe here some of these measurement methods as well as several analytical methods for assessing similarities and differences among pairs of surfaces. We also provide a few examples of research results to identify cartridge cases originating from the same firearm or tool marks produced by the same tool. Physical standards and issues of traceability are also discussed. PMID:27182440

MURMoT. Design and Application of Microbial Uranium Reduction Monitoring Tools

Energy Technology Data Exchange (ETDEWEB)

Loeffler, Frank E. [Univ. of Tennessee, Knoxville, TN (United States)

2014-12-31

Uranium (U) contamination in the subsurface is a major remediation challenge at many DOE sites. Traditional site remedies present enormous costs to DOE; hence, enhanced bioremediation technologies (i.e., biostimulation and bioaugmentation) combined with monitoring efforts are being considered as cost-effective corrective actions to address subsurface contamination. This research effort improved understanding of the microbial U reduction process and developed new tools for monitoring microbial activities. Application of these tools will promote science-based site management decisions that achieve contaminant detoxification, plume control, and long-term stewardship in the most efficient manner. The overarching hypothesis was that the design, validation and application of a suite of new molecular and biogeochemical tools advance process understanding, and improve environmental monitoring regimes to assess and predict in situ U immobilization. Accomplishments: This project (i) advanced nucleic acid-based approaches to elucidate the presence, abundance, dynamics, spatial distribution, and activity of metal- and radionuclide-detoxifying bacteria; (ii) developed proteomics workflows for detection of metal reduction biomarker proteins in laboratory cultures and contaminated site groundwater; (iii) developed and demonstrated the utility of U isotopic fractionation using high precision mass spectrometry to quantify U(VI) reduction for a range of reduction mechanisms and environmental conditions; and (iv) validated the new tools using field samples from U-contaminated IFRC sites, and demonstrated their prognostic and diagnostic capabilities in guiding decision making for environmental remediation and long-term site stewardship.

A methodology for string resolution

International Nuclear Information System (INIS)

Karonis, N.T.

1992-11-01

In this paper we present a methodology, not a tool. We present this methodology with the intent that it be adopted, on a case by case basis, by each of the existing tools in EPICS. In presenting this methodology, we describe each of its two components in detail and conclude with an example depicting how the methodology can be used across a pair of tools. The task of any control system is to provide access to the various components of the machine being controlled, for example, the Advanced Photon Source (APS). By access, we mean the ability to monitor the machine's status (reading) as well as the ability to explicitly change its status (writing). The Experimental Physics and Industrial Control System (EPICS) is a set of tools, designed to act in concert, that allows one to construct a control system. EPICS provides the ability to construct a control system that allows reading and writing access to the machine. It does this through the notion of databases. Each of the components of the APS that is accessed by the control system is represented in EPICS by a set of named database records. Once this abstraction is made, from physical device to named database records, the process of monitoring and changing the state of that device becomes the simple process of reading and writing information from and to its associated named records

2012-01-25

As Semantic Web technologies mature and new releases of key elements, such as SPARQL 1.1 and OWL 2.0, become available, the Life Sciences continue to push the boundaries of these technologies with ever more sophisticated tools and applications. Unsurprisingly, therefore, interest in the SWAT4LS (Semantic Web Applications and Tools for the Life Sciences) activities have remained high, as was evident during the third international SWAT4LS workshop held in Berlin in December 2010. Contributors to this workshop were invited to submit extended versions of their papers, the best of which are now made available in the special supplement of BMC Bioinformatics. The papers reflect the wide range of work in this area, covering the storage and querying of Life Sciences data in RDF triple stores, tools for the development of biomedical ontologies and the semantics-based integration of Life Sciences as well as clinicial data.

UNE MYTHOCRITIQUE DE LA CHANSON DE GUILLAUME EST-ELLE POSSIBLE ?

Full Text Available The main aim of the present study is to examine the appropriateness of myth criticism methods in the context of medieval French literature. The first part of the essay is conceived as a brief confrontation, opposing the theory of Mircea Eliade concerning the repetition of the Hero Archetype in traditional epics to some textual elements in the chansons de geste, analogous to “visible mythemes” which tend to appear in popular epic poetry. Through a series of comparisons, we come to the conclusion that the interpretation to which the “eliadian” scheme leads us expands the boundaries of a literary myth (an academic invisible and rather aspires to a “theology of text” (a lived invisible. The second part of the article provides the reader with a practical application of the results of the preceding reflections, and includes an interpretation of the story of Vivien based on the Christian concept of Imitatio Christi.

Epics, popular culture and politics in a modern work of art

Full Text Available “Death in Dallas” is a video-installation by Zoran Naskovski comprised of a visual documentary material connected to the assassination of John Fitzgerald Kennedy, the president of the USA and materials about his public and private life; b a soundtrack comprised of a poem accompanied by gusle by Jozo Karamatić with decasyllabic lyrics “Death in Dallas” by Božo Lasić. The unexpected and strange combo birthed a work of art which contains different layers of meaning and one of the most complete postmodern works of art in Serbian modern art. Naskovski had combined the seemingly incompatible codes of popular culture into a specific artistic method of its own genre – “Balkan noise”. Using the method of “noise” music, in which every noise, soundscape or voice has equal meaning and value; he included epics, tradition, politics, popular and folk culture. Finally, by doing so he had completely shifted the paradigm from modern to postmodern, from the substance of myth to a demystification of this type of representation.

Sulfate, nitrate and blood pressure - An EPIC interaction between sulfur and nitrogen.

Kuhnle, Gunter G; Luben, Robert; Khaw, Kay-Tee; Feelisch, Martin

Nitrate (NO 3 - )-rich foods such as green leafy vegetables are not only part of a healthy diet, but increasingly marketed for primary prevention of cardiovascular disease (CVD) and used as ergogenic aids by competitive athletes. While there is abundant evidence for mild hypotensive effects of nitrate on acute application there is limited data on chronic intake in humans, and results from animal studies suggest no long-term benefit. This is important as nitrate can also promote the formation of nitrosamines. It is therefore classified as 'probably carcinogenic to humans', although a beneficial effect on CVD risk might compensate for an increased cancer risk. Dietary nitrate requires reduction to nitrite (NO 2 - ) by oral commensal bacteria to contribute to the formation of nitric oxide (NO). The extensive crosstalk between NO and hydrogen sulfide (H 2 S) related metabolites may further affect nitrate's bioactivity. Using nitrate and nitrite concentrations of drinking water - the only dietary source continuously monitored for which detailed data exist - in conjunction with data of >14,000 participants of the EPIC-Norfolk study, we found no inverse associations with blood pressure or CVD risk. Instead, we found a strong interaction with sulfate (SO 4 2- ). At low sulfate concentrations, nitrate was inversely associated with BP (-4mmHg in top quintile) whereas this was reversed at higher concentrations (+3mmHg in top quintile). Our findings have a potentially significant impact for pharmacology, physiology and public health, redirecting our attention from the oral microbiome and mouthwash use to interaction with sulfur-containing dietary constituents. These results also indicate that nitrate bioactivation is more complex than hitherto assumed. The modulation of nitrate bioactivity by sulfate may render dietary lifestyle interventions aimed at increasing nitrate intake ineffective and even reverse potential antihypertensive effects, warranting further investigation

Practical applications of surface analytic tools in tribology

Science.gov (United States)

Ferrante, J.

1980-01-01

Many of the currently, widely used tools available for surface analysis are described. Those which have the highest applicability for giving elemental and/or compound analysis for problems of interest in tribology and are truly surface sensitive (that is, less than 10 atomic layers) are presented. The latter group is evaluated in detail in terms of strengths and weaknesses. Emphasis is placed on post facto analysis of experiments performed under 'real' conditions (e.g., in air with lubricants). It is further indicated that such equipment could be used for screening and quality control.

Full Text Available Object: Before epilepsy surgeries, intracranial electroencephalography (iEEG is often employed in function mapping and epileptogenic foci localization. Although the implanted electrodes provide crucial information for epileptogenic zone resection, a convenient clinical tool for electrode position registration and brain function mapping visualization is still lacking. In this study, we developed a Brain Function Mapping (BFM Tool, which facilitates electrode position registration and brain function mapping visualization, with an application to epilepsy surgeries.Methods: The BFM Tool mainly utilizes electrode location registration and function mapping based on pre-defined brain models from other software. In addition, the electrode node and mapping properties, such as the node size/color, edge color / thickness, mapping method, can be adjusted easily using the setting panel.

The scale of scientific High Performance Computing (HPC) and High Throughput Computing (HTC) has increased significantly in recent years, and is becoming sensitive to total energy use and cost. Energy-efficiency has thus become an important concern in scientific fields such as High Energy Physics (HEP). There has been a growing interest in utilizing alternate architectures, such as low power ARM processors, to replace traditional Intel x86 architectures. Nevertheless, even though such solutions have been successfully used in mobile applications with low I/O and memory demands, it is unclear if they are suitable and more energy-efficient in the scientific computing environment. Furthermore, there is a lack of tools and experience to derive and compare power consumption between the architectures for various workloads, and eventually to support software optimizations for energy efficiency. To that end, we have performed several physical and software-based measurements of workloads from HEP applications running on ARM and Intel architectures, and compare their power consumption and performance. We leverage several profiling tools (both in hardware and software) to extract different characteristics of the power use. We report the results of these measurements and the experience gained in developing a set of measurement techniques and profiling tools to accurately assess the power consumption for scientific workloads.

Geant4 is a tool kit developed by a collaboration of physicists and computer professionals in the High Energy Physics field for simulation of the passage of particles through matter. The motivation for the development of the Beam Tools is to extend the Geant4 applications to accelerator physics. Although there are many computer programs for beam physics simulations, Geant4 is ideal to model a beam going through material or a system with a beam line integrated to a complex detector. There are many examples in the current international High Energy Physics programs, such as studies related to a future Neutrino Factory, a Linear Collider, and a very Large Hadron Collider

A new methodology for empirical model validation has been proposed in the framework of the Task 22 (Building Energy Analysis Tools) of the International Energy Agency. It involves two main steps: checking model validity and diagnosis. Both steps, as well as the underlying methods, have been presented in the first part of the paper. In this part, they are applied for testing modelling hypothesis in the framework of the thermal analysis of an actual building. Sensitivity analysis tools have been first used to identify the parts of the model that can be really tested on the available data. A preliminary diagnosis is then supplied by principal components analysis. Useful information for model behaviour improvement has been finally obtained by optimisation techniques. This example of application shows how model parameters space analysis is a powerful tool for empirical validation. In particular, diagnosis possibilities are largely increased in comparison with residuals analysis techniques. (author)

2017-06-01

Full Text Available Rational application of pesticides by properly adjusting the amount of product to the actual needs and specific conditions for application is a key factor for sustainable plant protection. However, current plant protection product (PPP labels registered for citrus in EU are usually expressed as concentration (%; rate/hl and/or as the maximum dose of product per unit of ground surface, without taking into account those conditions. In this work, the fundamentals of a support tool, called CitrusVol, developed to recommend mix volume rates in PPP applications in citrus orchards using airblast sprayers, are presented. This tool takes into consideration crop characteristics (geometry, leaf area density, pests, and product and application efficiency, and it is based on scientific data obtained previously regarding the minimum deposit required to achieve maximum efficacy, efficiency of airblast sprayers in citrus orchards, and characterization of the crop. The use of this tool in several commercial orchards allowed a reduction of the volume rate and the PPPs used in comparison with the commonly used by farmers of between 11% and 74%, with an average of 31%, without affecting the efficacy. CitrusVol is freely available on a website and in an app for smartphones.

The operation of a 100-MeV linear proton accelerator, the major driving values and experimental data need to be archived. According to the experimental conditions, different data are required. Functions that can add new data and delete data in real time need to be implemented. In an experimental physics and industrial control system (EPICS) input output controller (IOC), the value of process variables (PVs) are matched with the driving values and data. The PV values are archived in text file format by using the channel archiver. There is no need to create a database (DB) server, just a need for large hard disk. Through the web, the archived data can be loaded, and new PV values can be archived without stopping the archive engine. The details of the implementation of a data archiving system with channel archiver are presented, and some preliminary results are reported.

2013-01-01

Process analytical technology (PAT) is used to monitor and control critical process parameters in raw materials and in-process products to maintain the critical quality attributes and build quality into the product. Process analytical technology can be successfully implemented in pharmaceutical and biopharmaceutical industries not only to impart quality into the products but also to prevent out-of-specifications and improve the productivity. PAT implementation eliminates the drawbacks of traditional methods which involves excessive sampling and facilitates rapid testing through direct sampling without any destruction of sample. However, to successfully adapt PAT tools into pharmaceutical and biopharmaceutical environment, thorough understanding of the process is needed along with mathematical and statistical tools to analyze large multidimensional spectral data generated by PAT tools. Chemometrics is a chemical discipline which incorporates both statistical and mathematical methods to obtain and analyze relevant information from PAT spectral tools. Applications of commonly used PAT tools in combination with appropriate chemometric method along with their advantages and working principle are discussed. Finally, systematic application of PAT tools in biopharmaceutical environment to control critical process parameters for achieving product quality is diagrammatically represented.

Hoffelner, W.; Samaras, M.; Bako, B.; Iglesias, R.

2008-01-01

The design of components for power plants is usually based on codes, standards and design rules or code cases. However, it is very difficult to get the necessary experimental data to prove these lifetime assessment procedures for long-term applications in environments where complex damage interactions (temperature, stress, environment, irradiation) can occur. The rules used are often very simple and do not have a basis which take physical damage into consideration. The linear life fraction rule for creep and fatigue interaction can be taken as a prominent example. Materials modelling based on a multi-scale approach in principle provides a tool to convert microstructural findings into mechanical response and therefore has the capability of providing a set of tools for the improvement of design life assessments. The strength of current multi-scale modelling efforts is the insight they offer as regards experimental phenomena. To obtain an understanding of these phenomena it is import to focus on issues which are important at the various time and length scales of the modelling code. In this presentation the multi-scale path will be demonstrated with a few recent examples which focus on VHTR applications. (authors)

Contemporary molecular tools in microbial ecology and their application to advancing biotechnology

KAUST Repository

Rashid, Mamoon; Stingl, Ulrich

2015-01-01

Novel methods in microbial ecology are revolutionizing our understanding of the structure and function of microbes in the environment, but concomitant advances in applications of these tools to biotechnology are mostly lagging behind. After more than a century of efforts to improve microbial culturing techniques, about 70–80% of microbial diversity – recently called the “microbial dark matter” – remains uncultured. In early attempts to identify and sample these so far uncultured taxonomic lineages, methods that amplify and sequence ribosomal RNA genes were extensively used. Recent developments in cell separation techniques, DNA amplification, and high-throughput DNA sequencing platforms have now made the discovery of genes/genomes of uncultured microorganisms from different environments possible through the use of metagenomic techniques and single-cell genomics. When used synergistically, these metagenomic and single-cell techniques create a powerful tool to study microbial diversity. These genomics techniques have already been successfully exploited to identify sources for i) novel enzymes or natural products for biotechnology applications, ii) novel genes from extremophiles, and iii) whole genomes or operons from uncultured microbes. More can be done to utilize these tools more efficiently in biotechnology.

The ultimate aim of the performance assessment methodology developed over the last 10-15 years is to predict quantitatively the behavior of disposal systems over periods of time into the far future. The methodology can, however, also be applied in range of tasks during repository development and is in many programmes used as a tool for improving or optimizing the design of subsystem components of for guiding the course of project planning. In Swiss waste management program, there are several examples of the use of performance assessment as a tool in the manner mentioned above. The interaction between research models, assessment models and simplified models is considered to be of key importance and corresponding measures are taken to properly structure the process and to track the data: first, the results of all applications of the models are included in a consistent manner in the scenario analyses for the different sites and systems and, second, consistency in the underlying assumptions and in the data used in the different model calculations is assured by the consequent application of a configuration data management system (CDM). Almost all the applications of performance assessment have been included in Swiss work, but for this paper, only two examples have been selected: applications of performance assessment in both the HLW and the LLW program; and acceptance of specific waste types and their allocation to an appropriate repository on the basis of simplified safety analyses

Applications and issues of GIS as tool for civil engineering modeling

1999-01-01

A tool that has proliferated within civil engineering in recent years is geographic information systems (GIS). The goal of a tool is to supplement ability and knowledge that already exists, not to serve as a replacement for that which is lacking. To secure the benefits and avoid misuse of a burgeoning tool, engineers must understand the limitations, alternatives, and context of the tool. The common benefits of using GIS as a supplement to engineering modeling are summarized. Several brief case studies of GIS modeling applications are taken from popular civil engineering literature to demonstrate the wide use and varied implementation of GIS across the discipline. Drawing from the case studies, limitations regarding traditional GIS data models find the implementation of civil engineering models within current GIS are identified and countered by discussing the direction of the next generation of GIS. The paper concludes by highlighting the potential for the misuse of GIS in the context of engineering modeling and suggests that this potential can be reduced through education and awareness. The goal of this paper is to promote awareness of the issues related to GIS-based modeling and to assist in the formulation of questions regarding the application of current GIS. The technology has experienced much publicity of late, with many engineers being perhaps too excited about the usefulness of current GIS. An undoubtedly beneficial side effect of this, however, is that engineers are becoming more aware of GIS and, hopefully, the associated subtleties. Civil engineers must stay informed of GIS issues and progress, but more importantly, civil engineers must inform the GIS community to direct the technology development optimally.

In 1987, New York Power Authority's Emergency and Process Information Computer (EPIC) System will be operational. The EPIC system was designed to perform two distinct functions: to serve as an advanced replacement for the existing plant process computer and to assist in providing the JAFNPP operations staff with information during plant emergency conditions. Besides meeting the operational and regulatory goals of NYPA, EPIC was designed to meet NYPA human factors criteria. Using human factors literature, industry standards and guidelines, a Human Factors Criteria document was prepared for the EPIC project. This document served as the bases for all hardware, display, and documentation design applicable to EPIC. The major tasks of the EPIC human factors plan include integration of past and present applicable human factors information, establishment of a user definition using data gathered from control room observations (startup and shutdown of JAFNPP), survey of computer programs used by the operators, and obtaining input from licensed operators. These major tasks played a role in the design of the design of the control room configuration, the design and development of computer generated displays, and the format in which the displayed and hard copy information would be presented to the user. This paper presents an overview of the human factors work performed and the documents researched or developed in the design of EPIC displays, software, and hardware. The location and operation of this new computer based information system, like the displays was based on the systematic application of operations and human factors principles

2005-01-01

The SCK.CEN developed during the BR3 reactor decommissioning a graphical interfaced 3D dose assessment tool aimed at the above mentioned dose optimization problems. The tool was improved further and commercialized under the name VISIPLAN 3D ALARA planning tool. The use of VISIPLAN tool at NPP A1 decommissioning was advised by EDF within the IAEA TCP SLR/4008 project missions as a component of a 3D technological chain ensuring acquisition and evaluation of digitized information leading to ALARA optimisation of the developed decommissioning working procedures (see Fig. 1). VISIPLAN license was purchased by IAEA and granted to VUJE and NPP A1 within the IAEA TCP project SLR/4008, covering also the necessary basic and advanced training (at NPP A1 real decommissioning environment), and is currently used by VUJE analysts at NPP A1 decommissioning as an ALARA tool for intervention planning and optimisation. The VISIPLAN allows a fast dose assessment for work planned in a radioactive environment. The calculations are based on a 3D model of the work place. This PC-based tool is user friendly and calculates a detailed dose account for different work scenarios defined by the ALARA analyst, taking into account worker position, work duration and subsequent geometry and source distribution changes. The VISIPLAN methodology is described. The VISIPLAN tool was applied to several ALARA studies carried out by the VUJE within development and analysis of various Work Programs for NPP Al decommissioning tasks. The applications ranged from simpler to complex ALARA planning tasks covering simple shielding applications to selection of the most suitable order of complex working procedures. Removal of inner liners from underground reservoirs 6/1 and 6/2 as well as Dismantling of pipes and components from a (hostile) 60 m corridor are described. (authors)

Computerized physician order entry has been shown to significantly improve chemotherapy safety by reducing the number of prescribing errors. Epic's Beacon Oncology Information System of computerized physician order entry and electronic medication administration was implemented in Henry Ford Health System's ambulatory oncology infusion centers on 9 November 2013. Since that time, compliance to the infusion workflow had not been assessed. The objective of this study was to optimize the current workflow and improve the compliance to this workflow in the ambulatory oncology setting. This study was a retrospective, quasi-experimental study which analyzed the composite workflow compliance rate of patient encounters from 9 to 23 November 2014. Based on this analysis, an intervention was identified and implemented in February 2015 to improve workflow compliance. The primary endpoint was to compare the composite compliance rate to the Beacon workflow before and after a pharmacy-initiated intervention. The intervention, which was education of infusion center staff, was initiated by ambulatory-based, oncology pharmacists and implemented by a multi-disciplinary team of pharmacists and nurses. The composite compliance rate was then reassessed for patient encounters from 2 to 13 March 2015 in order to analyze the effects of the determined intervention on compliance. The initial analysis in November 2014 revealed a composite compliance rate of 38%, and data analysis after the intervention revealed a statistically significant increase in the composite compliance rate to 83% ( p < 0.001). This study supports a pharmacist-initiated educational intervention can improve compliance to an ambulatory, oncology infusion workflow.

Korea Mult-purpose Accelerator Complex (KOMAC) has been operating 100 MeV proton linear accelerator . For operating 100 MeV linac, various control system has been implemented such as vacuum, power supply, RCCS and etc. KOMAC is operating two beam lines so that clients can use 100 MeV proton beam for their experiment. KOMAC sends beam to beam line and target room using two dipole magnets and several quadrupole magnets. As demand for experiments and Radius Isotope using beam is increased, another beam line is under construction and RI beam line control system is need. To synchronize with KOMAC control system, RI beam line control system is based on Experimental Physics and Industrial control System (EPICS) software. The beam is transported to RI beam line to control magnet power supply and vacuum. Implementation of RI beam line control system is presented and some preliminary results are reported. The base RI beam line control system is implemented. It can control beam direction and vacuum. Comparing archived data and current data, RI beam line and control system will be improved. In the future, scroll pump and gate control system will be implemented using programmable logic controller PLC. RI beam interlock sequence will be added to KOMAC interlock system to protect linac.

Komiyama, M.; Fukunishi, N.; Uchiyama, A.

2012-01-01

RIKEN Radioactive Isotope Beam Factory (RIBF) is a cyclotron-based next-generation radioactive beam facility. RIBF uses two types of control systems; an experimental physics and industrial control system (EPICS)-based system and a group of several non-EPICS-based systems. For each control system there is a corresponding data archiving system in operation, and in order to unify these two data archives, since October 2009 we have been developing a new archiving system. This new data archive system, named RIBF Control Data Archive System (RIBFCAS), is required, at intervals between 1 - 60 s, to collect and store more than 3000 data generated by EPICS controlled devices through EPICS input/output controllers (IOCs). In addition, RIBFCAS must be able to combine the existing non-EPICS-based systems. To fulfill these requirements, a Java-based platform has been created, and client applications are based on Adobe AIR runtime. The RIBFCAS hardware system, therefore, consists of an application server, a database server and client-PCs. Presently, we have succeeded in stably acquiring approximately 3000 data from 22 IOCs every 10 s. Moreover, incorporation of the non-EPICS-based data archive system into RIBFCAS is now in progress.

Modeling and classification difficulties are fundamental issues in natural hazard assessment. A geographic information system (GIS) is a domain that requires users to use various tools to perform different types of spatial modeling. Bivariate statistical analysis (BSA) assists in hazard modeling. To perform this analysis, several calculations are required and the user has to transfer data from one format to another. Most researchers perform these calculations manually by using Microsoft Excel or other programs. This process is time consuming and carries a degree of uncertainty. The lack of proper tools to implement BSA in a GIS environment prompted this study. In this paper, a user-friendly tool, BSM (bivariate statistical modeler), for BSA technique is proposed. Three popular BSA techniques such as frequency ratio, weights-of-evidence, and evidential belief function models are applied in the newly proposed ArcMAP tool. This tool is programmed in Python and is created by a simple graphical user interface, which facilitates the improvement of model performance. The proposed tool implements BSA automatically, thus allowing numerous variables to be examined. To validate the capability and accuracy of this program, a pilot test area in Malaysia is selected and all three models are tested by using the proposed program. Area under curve is used to measure the success rate and prediction rate. Results demonstrate that the proposed program executes BSA with reasonable accuracy. The proposed BSA tool can be used in numerous applications, such as natural hazard, mineral potential, hydrological, and other engineering and environmental applications.

EPIC 203868608 is a source in the ~10 Myr old Upper Scorpius OB association. Using K2 photometry and ground-based follow-up observations, David et al. (2016) found that it consists of two brown dwarfs with a tertiary object at a projected separation of ~20 AU; the former objects appear to be a double-lined eclipsing binary with a period of 4.5 days. This is one of only two known eclipsing SB2s where both components are below the hydrogen-burning limit. We present additional follow-up observations of this system from the IGRINS high-resolution near-infrared spectrograph at McDonald Observatory. Our measured radial velocities do not follow the orbital solution presented by David et al. (2016). Instead, our combined IGRINS plus literature radial velocity dataset appears to indicate a period significantly different than that of the eclipsing binary obvious from the K2 light curve. We will discuss possible scenarios to account for the conflicting observations of this system.

Old Wine in New Bottles-The SPEAR Control System Upgrade

Energy Technology Data Exchange (ETDEWEB)

Rarback, Harvey

1999-10-19

The control systems for the SPEAR storage ring and injector were designed almost two decades ago and have worked reliably for us. Both systems are heavily dependent on the OpenVMS operating system and CAMAC. The realtime data reside in shared memory on a single computer for each control system. In order to use more modern client tools while preserving our investment in the hardware and software, we have installed an EPICS Portable Channel Access Server (CAS) on the control computers. The CAS will serve the existing realtime data as EPICS Process Variables (PVs) and allow us to use client tools like dm2k and IDL running on other workstations to more easily build new operator interfaces and develop accelerator physics programs. The CAS will also provide the infrastructure to help integrate new hardware controlled by EPICS Input/Output Controllers (IOCs).

The Spallation Neutron Source (SNS) is an accelerator-based neutron source being built in Tennessee by a partnership of six national laboratories. The control system components for the SNS were produced by personnel at the collaborating laboratories, by vendors of the equipment, and by commercial contractors. A number of different approaches were used to provide the programming for both the programmable logic controllers (PLCs) and the input-output controllers (IOCs) which were all based on the Experimental Physics and Industrial Control System (EPICS). For conventional facilities, both the PLCs and the IOCs were programmed under a commercial contract. The PLCs for the high power radio frequency system (HPRF) were programmed by the vendors of the equipment, while the IOCs were programmed by the collaborating laboratory. Finally, while the IOCs for the cryogenic systems were programmed at Oak Ridge, three different approaches were used to produce the PLC programming: some were programmed at Oak Ridge, some at TJNAF, and some at vendor sites. This paper discusses the status of the PLCs in the control system and the integration challenges encountered in the various approaches

Efficient Photometry In-Frame Calibration (EPIC) Gaussian Corrections for Automated Background Normalization of Rate-Tracked Satellite Imagery

Science.gov (United States)

Griesbach, J.; Wetterer, C.; Sydney, P.; Gerber, J.

Photometric processing of non-resolved Electro-Optical (EO) images has commonly required the use of dark and flat calibration frames that are obtained to correct for charge coupled device (CCD) dark (thermal) noise and CCD quantum efficiency/optical path vignetting effects respectively. It is necessary to account/calibrate for these effects so that the brightness of objects of interest (e.g. stars or resident space objects (RSOs)) may be measured in a consistent manner across the CCD field of view. Detected objects typically require further calibration using aperture photometry to compensate for sky background (shot noise). For this, annuluses are measured around each detected object whose contained pixels are used to estimate an average background level that is subtracted from the detected pixel measurements. In a new photometric calibration software tool developed for AFRL/RD, called Efficient Photometry In-Frame Calibration (EPIC), an automated background normalization technique is proposed that eliminates the requirement to capture dark and flat calibration images. The proposed technique simultaneously corrects for dark noise, shot noise, and CCD quantum efficiency/optical path vignetting effects. With this, a constant detection threshold may be applied for constant false alarm rate (CFAR) object detection without the need for aperture photometry corrections. The detected pixels may be simply summed (without further correction) for an accurate instrumental magnitude estimate. The noise distribution associated with each pixel is assumed to be sampled from a Poisson distribution. Since Poisson distributed data closely resembles Gaussian data for parameterized means greater than 10, the data may be corrected by applying bias subtraction and standard-deviation division. EPIC performs automated background normalization on rate-tracked satellite images using the following technique. A deck of approximately 50-100 images is combined by performing an independent median

Sustainability rating tools for buildings and its wider application

Siew Renard

2017-01-01

Full Text Available This paper provides a commentary on the latest research in measuring the sustainability of buildings and its wider application. The emergence of sustainability rating tools (SRTs has faced critique from scholars due to their deficiencies such as the overemphasis on environmental criteria, the negligence of uncertainty in scoring and existence of non-scientific criteria benchmarks among many others. This could have attributed to the mixed evidence in the literature on the benefits of SRTs. Future research direction is proposed to advance the state-of-the art in this field.

Moreira, Ana Maria Maniero; Günther, Wanda Maria Risso

2016-01-01

Abstract Objectives: to propose a tool to facilitate diagnosis, formulation and evaluation of the Waste Management Plan in Primary Healthcare Centers and to present the results of the application in four selected units. Method: descriptive research, covering the stages of formulation /application of the proposed instrument and the evaluation of waste management performance at the units. Results: the tool consists in five forms; specific indicators of waste generation for outpatients healthcare units were proposed, and performance indicators that give scores for compliance with current legislation. In the studied units it is generated common waste (52-60%), infectious-sharps (31-42%) and recyclable (5-17%). The average rates of generation are: 0,09kg of total waste/outpatient assistance and 0,09kg of infectious-sharps waste/outpatient procedure. The compliance with regulations, initially 26-30%, then reached 30-38% a year later. Conclusion: the tool showed to be easy to use, bypassing the existence of a complex range of existing regulatory requirements, allowed to identify non-conformities, pointed out corrective measures and evaluated the performance of waste management. In this sense, it contributes to decision making and management practices relating to waste, tasks usually assigned to nurses. It is recommended that the tool be applied in similar healthcare units for comparative studies, and implementation of necessary adaptations for other medical services. PMID:27556874

Design of an instrumented smart cutting tool and its implementation and application perspectives

International Nuclear Information System (INIS)

Wang, Chao; Cheng, Kai; Chen, Xun; Minton, Timothy; Rakowski, Richard

2014-01-01

This paper presents an innovative design of a smart cutting tool, using two surface acoustic wave (SAW) strain sensors mounted onto the top and the side surface of the tool shank respectively, and its implementation and application perspectives. This surface acoustic wave-based smart cutting tool is capable of measuring the cutting force and the feed force in a real machining environment, after a calibration process under known cutting conditions. A hybrid dissimilar workpiece is then machined using the SAW-based smart cutting tool. The hybrid dissimilar material is made of two different materials, NiCu alloy (Monel) and steel, welded together to form a single bar; this can be used to simulate an abrupt change in material properties. The property transition zone is successfully detected by the tool; the sensor feedback can then be used to initiate a change in the machining parameters to compensate for the altered material properties.

Application of Statistical Tools for Data Analysis and Interpretation in Rice Plant Pathology

Directory of Open Access Journals (Sweden)

Parsuram Nayak

2018-01-01

Full Text Available There has been a significant advancement in the application of statistical tools in plant pathology during the past four decades. These tools include multivariate analysis of disease dynamics involving principal component analysis, cluster analysis, factor analysis, pattern analysis, discriminant analysis, multivariate analysis of variance, correspondence analysis, canonical correlation analysis, redundancy analysis, genetic diversity analysis, and stability analysis, which involve in joint regression, additive main effects and multiplicative interactions, and genotype-by-environment interaction biplot analysis. The advanced statistical tools, such as non-parametric analysis of disease association, meta-analysis, Bayesian analysis, and decision theory, take an important place in analysis of disease dynamics. Disease forecasting methods by simulation models for plant diseases have a great potentiality in practical disease control strategies. Common mathematical tools such as monomolecular, exponential, logistic, Gompertz and linked differential equations take an important place in growth curve analysis of disease epidemics. The highly informative means of displaying a range of numerical data through construction of box and whisker plots has been suggested. The probable applications of recent advanced tools of linear and non-linear mixed models like the linear mixed model, generalized linear model, and generalized linear mixed models have been presented. The most recent technologies such as micro-array analysis, though cost effective, provide estimates of gene expressions for thousands of genes simultaneously and need attention by the molecular biologists. Some of these advanced tools can be well applied in different branches of rice research, including crop improvement, crop production, crop protection, social sciences as well as agricultural engineering. The rice research scientists should take advantage of these new opportunities adequately in

Cock, Peter J A; Grüning, Björn A; Paszkiewicz, Konrad; Pritchard, Leighton

2013-01-01

The Galaxy Project offers the popular web browser-based platform Galaxy for running bioinformatics tools and constructing simple workflows. Here, we present a broad collection of additional Galaxy tools for large scale analysis of gene and protein sequences. The motivating research theme is the identification of specific genes of interest in a range of non-model organisms, and our central example is the identification and prediction of "effector" proteins produced by plant pathogens in order to manipulate their host plant. This functional annotation of a pathogen's predicted capacity for virulence is a key step in translating sequence data into potential applications in plant pathology. This collection includes novel tools, and widely-used third-party tools such as NCBI BLAST+ wrapped for use within Galaxy. Individual bioinformatics software tools are typically available separately as standalone packages, or in online browser-based form. The Galaxy framework enables the user to combine these and other tools to automate organism scale analyses as workflows, without demanding familiarity with command line tools and scripting. Workflows created using Galaxy can be saved and are reusable, so may be distributed within and between research groups, facilitating the construction of a set of standardised, reusable bioinformatic protocols. The Galaxy tools and workflows described in this manuscript are open source and freely available from the Galaxy Tool Shed (http://usegalaxy.org/toolshed or http://toolshed.g2.bx.psu.edu).

The IRMIS object model and services API

Saunders, C.; Dohan, D.A.; Arnold, N.D.

2005-01-01

The relational model developed for the Integrated Relational Model of Installed Systems (IRMIS) toolkit has been successfully used to capture the Advanced Photon Source (APS) control system software (EPICS process variables and their definitions). The relational tables are populated by a crawler script that parses each Input/Output Controller (IOC) start-up file when an IOC reboot is detected. User interaction is provided by a Java Swing application that acts as a desktop for viewing the process variable information. Mapping between the display objects and the relational tables was carried out with the Hibernate Object Relational Modeling (ORM) framework. Work is well underway at the APS to extend the relational modeling to include control system hardware. For this work, due in part to the complex user interaction required, the primary application development environment has shifted from the relational database view to the object oriented (Java) perspective. With this approach, the business logic is executed in Java rather than in SQL stored procedures. This paper describes the object model used to represent control system software, hardware, and interconnects in IRMIS. We also describe the services API used to encapsulate the required behaviors for creating and maintaining the complex data. In addition to the core schema and object model, many important concepts in IRMIS are captured by the services API. IRMIS is an ambitious collaborative effort for defining and developing a relational database and associated applications to comprehensively document the large and complex EPICS-based control systems of today's accelerators. The documentation effort includes process variables, control system hardware, and interconnections. The approach could also be used to document all components of the accelerator, including mechanical, vacuum, power supplies, etc. One key aspect of IRMIS is that it is a documentation framework, not a design and development tool. We do not

Jenni, F

2006-01-01

In the last two decades, simulation tools made a significant contribution to the great progress in development of power electronics. Time to market was shortened and development costs were reduced drastically. Falling costs, as well as improved speed and precision, opened new fields of application. Today, continuous and switched circuits can be mixed. A comfortable number of powerful simulation tools is available. The users have to choose the best suitable for their application. Here a simple rule applies: The best available simulation tool is the tool the user is already used to (provided, it can solve the task). Abilities, speed, user friendliness and other features are continuously being improved—even though they are already powerful and comfortable. This paper aims at giving the reader an insight into the simulation of power electronics. Starting with a short description of the fundamentals of a simulation tool as well as properties of tools, several tools are presented. Starting with simplified models ...

L’image du Turc dans la poésie épique serbe The image of Turk in the epic serbian poetry

Full Text Available L’œuvre de Vuk Karadjitch et son évocation de l’image du Turc dans la poésie épique serbe. Persuadé que la poésie épique serbe porte une valeur exceptionnelle dans la formation de la langue elle-même ainsi que dans la constitution de l’identité nationale et de la mémoire collective, Vuk Karadjitch se hâte, durant toute sa vie, de rencontrer les chanteurs épiques-aèdes pour les écouter et noter les poèmes. C’est ainsi qu’il réussit à recueillir environ mille chants populaires.Les critères de systématisation de Vuk Karadjitch prennent en compte le contenu thématique des poèmes. Il divise les chants en deux familles : les poèmes féminins traitant des sujets appropriés, et les poèmes masculins qui évoquent les thèmes héroïques, les batailles, les guerres, les personnages et les événements importants de l’histoire. Les chants masculins sont au centre de nos recherches dans cette étude. Ces poèmes qui parlent des batailles sanglantes et de l’héroïsme national se situent historiquement à l’époque de l’envahissement turc des territoires serbes. Selon les différentes périodes de l’occupation ottomane, on peut voir l’évolution de l’image de l’occupant turc, construite dans l’imaginaire collectif. Dans la présence turque, les Serbes ne voyaient pas seulement l’envahisseur cruel, mais surtout leur propre échec qui les fait appeler constamment à la vengeance et à la révolte. En ce sens, la poésie épique serbe de l’époque de la domination turque n’est qu’une longue épopée sur un thème unique : la liberté.Persuaded that epic Serbian poetry plays an exceptional part in the formation of the language itself as well as in the constitution of a national identity and collective memory, Vuk Karadjich hurries throughout his life to meet traditional epic-singers and note down their poems. It is in this way he is able to collect around one thousand popular songs.Vuk Karadjich�

Application of lean tools in the supply chain of a maintenance environment

Full Text Available Historically, Lean thinking has limited applications in the maintenance environment (that is, a non-manufacturing environment. This article reports on the Lean tools that can be implemented in the maintenance environment. To achieve this, a typical supply chain management of a rolling stock service organisation was used for analysis and validation. The approach was initially to map the current supply chain process through a standard method of value stream mapping so as to identify non-Lean activities. After mapping the current state, other suitable Lean tools for the current supply chain management were applied. Finally, performance Indicators were formulated for continuous review and assessment.

Tools for Empirical and Operational Analysis of Mobile Offloading in Loop-Based Applications

Directory of Open Access Journals (Sweden)

Alexandru-Corneliu OLTEANU

2013-01-01

Full Text Available Offloading for mobile devices is an increasingly popular research topic, matching the popu-larity mobile devices have in the general population. Studying mobile offloading is challenging because of device and application heterogeneity. However, we believe that focusing on a specific type of application can bring advances in offloading for mobile devices, while still keeping a wide range of applicability. In this paper we focus on loop-based applications, in which most of the functionality is given by iterating an execution loop. We model the main loop of the application with a graph that consists of a cycle and propose an operational analysis to study offloading on this model. We also propose a testbed based on a real-world application to empirically evaluate offloading. We conduct performance evaluation using both tools and compare the analytical and empirical results.

BioTapestry now provides a web application and improved drawing and layout tools.

Paquette, Suzanne M; Leinonen, Kalle; Longabaugh, William J R

2016-01-01

Gene regulatory networks (GRNs) control embryonic development, and to understand this process in depth, researchers need to have a detailed understanding of both the network architecture and its dynamic evolution over time and space. Interactive visualization tools better enable researchers to conceptualize, understand, and share GRN models. BioTapestry is an established application designed to fill this role, and recent enhancements released in Versions 6 and 7 have targeted two major facets of the program. First, we introduced significant improvements for network drawing and automatic layout that have now made it much easier for the user to create larger, more organized network drawings. Second, we revised the program architecture so it could continue to support the current Java desktop Editor program, while introducing a new BioTapestry GRN Viewer that runs as a JavaScript web application in a browser. We have deployed a number of GRN models using this new web application. These improvements will ensure that BioTapestry remains viable as a research tool in the face of the continuing evolution of web technologies, and as our understanding of GRN models grows.

Research has shown that mobile applications provide a powerful alternative to traditional paper diaries; however, little data exists in comparing apps to the traditional mode of paper as a patient education and engagement tool in the clinical setting. This study was designed to compare the effectiveness of a mobile app versus a spiral-notebook guide throughout prenatal care. This randomized (n=173) controlled pilot was conducted at an East Coast community hospital. Chi-square and repeated-measures analysis of variance was used to test intervention effects in the sample of 127 pregnant mothers who completed their prenatal care in the healthcare system. Patients who were distributed the mobile application used the tool to record information about pregnancy more frequently (p=.04) and developed greater patient activation (p=.02) than patients who were distributed notebooks. No difference was detected on interpersonal clinical communication. A mobile application successfully activated a patient population in which self-management is a critical factor. This study shows that mobile apps can prompt greater use and result in more activated patients. Findings may be translated to other patient populations who receive recurring care for chronic disease.

Friend, Tynan H; Jennings, Samantha J; Levine, Wilton C

2017-02-01

In April 2016, Massachusetts General Hospital (MGH) went live with the Epic electronic health records (EHR) system, replacing a variety of EHRs that previously existed in different departments throughout the hospital. At the time of implementation, the Vocera® Badge Communication System, a wireless hands-free communication device distributed to perioperative team members, had increased perioperative communication flow and efficiency. As a quality improvement effort to better understand communication patterns during an EHR go-live, we monitored our Vocera call volume and user volume before, during and after our go-live. We noticed that call volume and user volume significantly increased during our immediate go-live period and quickly returned to baseline levels. We also noticed that call volume increased during periods of unplanned EHR downtime long after our immediate go-live period. When planning the implementation of a new EHR, leadership must plan for and support this critical communication need at the time of the go-live and must also be aware of these needs during unplanned downtime.

Verrucci, Enrica; Bevington, John; Vicini, Alessandro

2014-05-01

A set of open-source tools to create building exposure datasets for seismic risk assessment was developed from 2010-13 by the Inventory Data Capture Tools (IDCT) Risk Global Component of the Global Earthquake Model (GEM). The tools were designed to integrate data derived from remotely-sensed imagery, statistically-sampled in-situ field data of buildings to generate per-building and regional exposure data. A number of software tools were created to aid the development of these data, including mobile data capture tools for in-field structural assessment, and the Spatial Inventory Data Developer (SIDD) for creating "mapping schemes" - statistically-inferred distributions of building stock applied to areas of homogeneous urban land use. These tools were made publically available in January 2014. Exemplar implementations in Europe and Central Asia during the IDCT project highlighted several potential application areas beyond the original scope of the project. These are investigated here. We describe and demonstrate how the GEM-IDCT suite can be used extensively within the framework proposed by the EC-FP7 project SENSUM (Framework to integrate Space-based and in-situ sENSing for dynamic vUlnerability and recovery Monitoring). Specifically, applications in the areas of 1) dynamic vulnerability assessment (pre-event), and 2) recovery monitoring and evaluation (post-event) are discussed. Strategies for using the IDC Tools for these purposes are discussed. The results demonstrate the benefits of using advanced technology tools for data capture, especially in a systematic fashion using the taxonomic standards set by GEM. Originally designed for seismic risk assessment, it is clear the IDCT tools have relevance for multi-hazard risk assessment. When combined with a suitable sampling framework and applied to multi-temporal recovery monitoring, data generated from the tools can reveal spatio-temporal patterns in the quality of recovery activities and resilience trends can be

Full Text Available Abstract Background Common information facilities do not always provide the quality information needed to answer questions on health or health-related issues, such as Occupational Safety and Health (OSH matters. Barriers may be the accessibility, quantity and readability of information. Online Question & Answer (Q&A network tools, which link questioners directly to experts can overcome some of these barriers. When designing and testing online tools, assessing the usability and applicability is essential. Therefore, the purpose of this study is to assess the usability and applicability of a new online Q&A network tool for answers on OSH questions. Methods We applied a cross-sectional usability test design. Eight occupational health experts and twelve potential questioners from the working population (workers were purposively selected to include a variety of computer- and internet-experiences. During the test, participants were first observed while executing eight tasks that entailed important features of the tool. In addition, they were interviewed. Through task observations and interviews we assessed applicability, usability (effectiveness, efficiency and satisfaction and facilitators and barriers in use. Results Most features were usable, though several could be improved. Most tasks were executed effectively. Some tasks, for example searching stored questions in categories, were not executed efficiently and participants were less satisfied with the corresponding features. Participants' recommendations led to improvements. The tool was found mostly applicable for additional information, to observe new OSH trends and to improve contact between OSH experts and workers. Hosting and support by a trustworthy professional organization, effective implementation campaigns, timely answering and anonymity were seen as important use requirements. Conclusions This network tool is a promising new strategy for offering company workers high quality information

Cultural Trauma and Christian Identity in the Late Medieval Heroic Epic, The Siege of Jerusalem.

DeMarco, Patricia A

2015-01-01

This essay examines scenes of violence in the late medieval poem The Siege of Jerusalem in order to reveal the ways in which trauma is used as the grounds upon which Christian/Jewish difference is established. In particular, I argue that this poem serves as an example of a widespread element in Christian chivalric identity, namely the need to manage the repetitive invocation of Christ's crucifixion (ritually repeated through liturgical and poetic invocation) as a means of asserting both the bodily and psychic integrity of the Christian subject in contrast to the violently abjected figure of the Jewish body. The failure of The Siege protagonist, Wespasian, to navigate the cultural trauma of the crucifixion is contrasted to the successful management of trauma by the martial hero, Tancred, in Tasso's epic, Gerusalemme Liberata, illustrating the range of imaginative possibilities for understanding trauma in pre-modern war literature.

This document describes a recently developed analysis tool that enhances the resident capabilities of the Micromechanics Analysis Code with the Generalized Method of Cells (MAC/GMC) and its application. MAC/GMC is a composite material and laminate analysis software package developed at NASA Glenn Research Center. The primary focus of the current effort is to provide a graphical user interface (GUI) capability that helps users optimize highly nonlinear viscoplastic constitutive law parameters by fitting experimentally observed/measured stress-strain responses under various thermo-mechanical conditions for braided composites. The tool has been developed utilizing the MATrix LABoratory (MATLAB) (The Mathworks, Inc., Natick, MA) programming language. Illustrative examples shown are for a specific braided composite system wherein the matrix viscoplastic behavior is represented by a constitutive law described by seven parameters. The tool is general enough to fit any number of experimentally observed stress-strain responses of the material. The number of parameters to be optimized, as well as the importance given to each stress-strain response, are user choice. Three different optimization algorithms are included: (1) Optimization based on gradient method, (2) Genetic algorithm (GA) based optimization and (3) Particle Swarm Optimization (PSO). The user can mix and match the three algorithms. For example, one can start optimization with either 2 or 3 and then use the optimized solution to further fine tune with approach 1. The secondary focus of this paper is to demonstrate the application of this tool to optimize/calibrate parameters for a nonlinear viscoplastic matrix to predict stress-strain curves (for constituent and composite levels) at different rates, temperatures and/or loading conditions utilizing the Generalized Method of Cells. After preliminary validation of the tool through comparison with experimental results, a detailed virtual parametric study is

Frequently left brain damage (LBD) leads to limb apraxia, a disorder that can affect tool-use. Despite its impact on daily life, classical tests examining the pantomime of tool-use and imitation of gestures are seldom applied in clinical practice. The study's aim was to present a diagnostic approach which appears more strongly related to actions in daily life in order to sensitize applicants and patients about the relevance of the disorder before patients are discharged. Two tests were introduced that evaluate actual tool selection and tool-object-application: the Novel Tools (NTT) and the Familiar Tools (FTT) Test (parts of the DILA-S: Diagnostic Instrument for Limb Apraxia - Short Version). Normative data in healthy subjects (N = 82) was collected. Then the tests were applied in stroke patients with unilateral left brain damage (LBD: N = 33), a control right brain damage group (RBD: N = 20) as well as healthy age and gender matched controls (CL: N = 28, and CR, N = 18). The tests showed appropriate interrater-reliability and internal consistency as well as concurrent and divergent validity. To examine criterion validity based on the well-known left lateralization of limb apraxia, group comparisons were run. As expected, the LBD group demonstrated a high prevalence of tool-use apraxia (NTT: 36.4%, FTT: 48.5%) ranging from mild to severe impairment and scored worse than their control group (CL). A few RBD patients did demonstrate impairments in tool-use (NTT: 15%, FTT: 15%). On a group level they did not differ from their healthy controls (CR). Further, it was demonstrated that the selection and application of familiar and novel tools can be impaired selectively. Our study results suggest that real tool-use tests evaluating tool selection and tool application should be considered for standard diagnosis of limb apraxia in left as well as right brain damaged patients.

Ergodic optimization in the expanding case concepts, tools and applications

CERN Document Server

Garibaldi, Eduardo

2017-01-01

This book focuses on the interpretation of ergodic optimal problems as questions of variational dynamics, employing a comparable approach to that of the Aubry-Mather theory for Lagrangian systems. Ergodic optimization is primarily concerned with the study of optimizing probability measures. This work presents and discusses the fundamental concepts of the theory, including the use and relevance of Sub-actions as analogues to subsolutions of the Hamilton-Jacobi equation. Further, it provides evidence for the impressively broad applicability of the tools inspired by the weak KAM theory.

Using the missed opportunity tool as an application of the Lives Saved Tool (LiST) for intervention prioritization.

The Missed Opportunity tool was developed as an application in the Lives Saved Tool (LiST) to allow users to quickly compare the relative impact of interventions. Global Financing Facility (GFF) investment cases have been identified as a potential application of the Missed Opportunity analyses in Democratic Republic of the Congo (DRC), Ethiopia, Kenya, and Tanzania, to use 'lives saved' as a normative factor to set priorities. The Missed Opportunity analysis draws on data and methods in LiST to project maternal, stillbirth, and child deaths averted based on changes in interventions' coverage. Coverage of each individual intervention in LiST was automated to be scaled up from current coverage to 90% in the next year, to simulate a scenario where almost every mother and child receive proven interventions that they need. The main outcome of the Missed Opportunity analysis is deaths averted due to each intervention. When reducing unmet need for contraception is included in the analysis, it ranks as the top missed opportunity across the four countries. When it is not included in the analysis, top interventions with the most total deaths averted are hospital-based interventions such as labor and delivery management in the CEmOC and BEmOC level, and full treatment and supportive care for premature babies, and for sepsis/pneumonia. The Missed Opportunity tool can be used to provide a quick, first look at missed opportunities in a country or geographic region, and help identify interventions for prioritization. While it is a useful advocate for evidence-based priority setting, decision makers need to consider other factors that influence decision making, and also discuss how to implement, deliver, and sustain programs to achieve high coverage.

Full Text Available The European Prospective Investigation into Cancer and nutrition (EPIC is a long-term, multi-centric prospective study in Europe investigating the relationships between cancer and nutrition. This study has served as a basis for a number of Genome-Wide Association Studies (GWAS and other types of genetic analyses. Over a period of 5 years, 52,256 EPIC DNA samples have been extracted using an automated DNA extraction platform. Here we have evaluated the pre-analytical factors affecting DNA yield, including anthropometric, epidemiological and technical factors such as center of subject recruitment, age, gender, body-mass index, disease case or control status, tobacco consumption, number of aliquots of buffy coat used for DNA extraction, extraction machine or procedure, DNA quantification method, degree of haemolysis and variations in the timing of sample processing. We show that the largest significant variations in DNA yield were observed with degree of haemolysis and with center of subject recruitment. Age, gender, body-mass index, cancer case or control status and tobacco consumption also significantly impacted DNA yield. Feedback from laboratories which have analyzed DNA with different SNP genotyping technologies demonstrate that the vast majority of samples (approximately 88% performed adequately in different types of assays. To our knowledge this study is the largest to date to evaluate the sources of pre-analytical variations in DNA extracted from peripheral leucocytes. The results provide a strong evidence-based rationale for standardized recommendations on blood collection and processing protocols for large-scale genetic studies.

Chee, T.; Nguyen, L.; Minnis, P.; Spangenberg, D.; Ayers, J.

2013-12-01

Providing access to information is a key concern for NASA Langley Research Center. We describe a tool and method that allows end users to easily browse and access information that is otherwise difficult to acquire and manipulate. The tool described has as its core the application-programming interface that is made available to the public. One goal of the tool is to provide a demonstration to end users so that they can use the enhanced imagery as an input into their own work flows. This project builds upon NASA Langley Cloud and Radiation Group's experience with making real-time and historical satellite imagery accessible and easily searchable. As we see the increasing use of virtual supply chains that provide additional value at each link there is value in making satellite imagery available through a simple access method as well as allowing users to browse and view that imagery as they need rather than in a manner most convenient for the data provider.

Dallas, Lorna J; Jha, Awadhesh N

2015-06-30

Biological systems are the ultimate recipients of pollutant-induced damage. Consequently, our traditional reliance on analytical tools is not enough to assess ecosystem health. Biological responses or biomarkers are therefore also considered to be important tools for environmental hazard and risk assessments. Due to historical mining, other anthropogenic activities, and its conservational importance (e.g. NATURA sites, SACs), the Tamar estuary in South West England is an ideal environment in which to examine applications of such biological tools. This review presents a thorough and critical evaluation of the different biological tools used in the Tamar estuary thus far, while also discussing future perspectives for biomarker studies from a global perspective. In particular, we focus on the challenges which hinder applications of biological tools from being more readily incorporated into regulatory frameworks, with the aim of enabling both policymakers and primary stakeholders to maximise the environmental relevance and regulatory usefulness of such tools.

The aim of this study was to examine the association of body mass index (BMI) and weight gain with eating at restaurants and similar establishments or eating at work among 10 European countries of the European Prospective Investigation into Cancer and Nutrition (EPIC) study. This study included a representative sample of 24,310 randomly selected EPIC participants. Single 24-h dietary recalls with information on the place of consumption were collected using standardized procedures between 1995 and 2000. Eating at restaurants was defined to include all eating and drinking occasions at restaurants, cafeterias, bars and fast food outlets. Eating at work included all eating and drinking occasions at the workplace. Associations between eating at restaurants or eating at work and BMI or annual weight changes were assessed using sex-specific linear mixed-effects models, controlling for potential confounders. In southern Europe energy intake at restaurants was higher than intake at work, whereas in northern Europe eating at work appeared to contribute more to the mean daily intake than eating at restaurants. Cross-sectionally, eating at restaurants was found to be positively associated with BMI only among men (β=+0.24, P=0.003). Essentially no association was found between BMI and eating at work among both genders. In a prospective analysis among men, eating at restaurants was found to be positively, albeit nonsignificantly, associated with weight gain (β=+0.05, P=0.368). No association was detected between energy intake at restaurants and weight changes, controlling for total energy intake. Among men, eating at restaurants and similar establishments was associated with higher BMI and possibly weight gain.

Cytogenetic chromosome maps offer molecular tools for genome analysis and clinical cytogenetics and are of particular importance for species with difficult karyotypes, such as camelids (2n = 74). Building on the available human–camel zoo-fluorescence in situ hybridization (FISH) data, we developed the first cytogenetic map for the alpaca (Lama pacos, LPA) genome by isolating and identifying 151 alpaca bacterial artificial chromosome (BAC) clones corresponding to 44 specific genes. The genes were mapped by FISH to 31 alpaca autosomes and the sex chromosomes; 11 chromosomes had 2 markers, which were ordered by dual-color FISH. The STS gene mapped to Xpter/Ypter, demarcating the pseudoautosomal region, whereas no markers were assigned to chromosomes 14, 21, 22, 28, and 36. The chromosome-specific markers were applied in clinical cytogenetics to identify LPA20, the major histocompatibility complex (MHC)-carrying chromosome, as a part of an autosomal translocation in a sterile male llama (Lama glama, LGL; 2n = 73,XY). FISH with LPAX BACs and LPA36 paints, as well as comparative genomic hybridization, were also used to investigate the origin of the minute chromosome, an abnormally small LPA36 in infertile female alpacas. This collection of cytogenetically mapped markers represents a new tool for camelid clinical cytogenetics and has applications for the improvement of the alpaca genome map and sequence assembly.

Full Text Available The mTOR (mammalian target of rapamycin signal transduction pathway integrates various signals, regulating ribosome biogenesis and protein synthesis as a function of available energy and amino acids, and assuring an appropriate coupling of cellular proliferation with increases in cell size. In addition, recent evidence has pointed to an interplay between the mTOR and p53 pathways. We investigated the genetic variability of 67 key genes in the mTOR pathway and in genes of the p53 pathway which interact with mTOR. We tested the association of 1,084 tagging SNPs with prostate cancer risk in a study of 815 prostate cancer cases and 1,266 controls nested within the European Prospective Investigation into Cancer and Nutrition (EPIC. We chose the SNPs (n = 11 with the strongest association with risk (p<0.01 and sought to replicate their association in an additional series of 838 prostate cancer cases and 943 controls from EPIC. In the joint analysis of first and second phase two SNPs of the PRKCI gene showed an association with risk of prostate cancer (OR(allele = 0.85, 95% CI 0.78-0.94, p = 1.3 x 10⁻³ for rs546950 and OR(allele = 0.84, 95% CI 0.76-0.93, p = 5.6 x 10⁻⁴ for rs4955720. We confirmed this in a meta-analysis using as replication set the data from the second phase of our study jointly with the first phase of the Cancer Genetic Markers of Susceptibility (CGEMS project. In conclusion, we found an association with prostate cancer risk for two SNPs belonging to PRKCI, a gene which is frequently overexpressed in various neoplasms, including prostate cancer.

Purpose: The new short Expanded Prostate Cancer Index Composite for Clinical Practice (EPIC-CP) patient-reported health-related quality of life (HRQOL) tool has removed the rectal bleeding question from the previous much longer version, EPIC-26. Herein, we assess the impact of losing the dedicated rectal bleeding question in 2 independent prospective multicenter cohorts. Methods and Materials: In a prospective multicenter test cohort (n=865), EPIC-26 patient-reported HRQOL data were collected for 2 years after treatment from patients treated with prostate radiation therapy from 2003 to 2011. A second prospective multicenter cohort (n=442) was used for independent validation. A repeated-effects model was used to predict the change from baseline in bowel summary scores from longer EPIC instruments using the change in EPIC-CP bowel summary scores with and without rectal bleeding scores. Results: Two years after radiation therapy, 91% of patients were free of bleeding, and only 2.6% reported bothersome bleeding problems. Correlations between EPIC-26 and EPIC-CP bowel scores were very high (r"2=0.90-0.96) and were statistically improved with the addition of rectal bleeding information (r"2=0.94-0.98). Considering all patients, only 0.2% of patients in the test cohort and 0.7% in the validation cohort reported bothersome bleeding and had clinically relevant HRQOL changes missed with EPIC-CP. However, of the 2.6% (n=17) of men with bothersome rectal bleeding in the test cohort, EPIC-CP failed to capture 1 patient (6%) as experiencing meaningful declines in bowel HRQOL. Conclusions: Modern prostate radiation therapy results in exceptionally low rates of bothersome rectal bleeding, and <1% of patients experience bothersome bleeding and are not captured by EPIC-CP as having meaningful HRQOL declines after radiation therapy. However, in the small subset of patients with bothersome rectal bleeding, the longer EPIC-26 should strongly be considered, given its superior

In the United States, young men who have sex with men (YMSM) and transgender women who have sex with men (YTWSM) bear a disproportionate burden of prevalent and incident HIV infections. Once diagnosed, many YMSM and YTWSM struggle to engage in HIV care, adhere to antiretroviral therapy (ART), and achieve viral suppression. Computer-based interventions, including those focused on behavior change, are recognized as effective tools for engaging youth. The purpose of the study described in this protocol is to evaluate the efficacy of Epic Allies, a theory-based mobile phone app that utilizes game mechanics and social networking features to improve engagement in HIV care, ART uptake, ART adherence, and viral suppression among HIV-positive YMSM and YTWSM. The study also qualitatively assesses intervention acceptability, perceived impact, and sustainability. This is a two-group, active-control randomized controlled trial of the Epic Allies app. YMSM and YTWSM aged 16 to 24 inclusive, with detectable HIV viral load are randomized 1:1 within strata of new to care (newly entered HIV medical care ≤12 months of baseline visit) or ART-nonadherent (first entered HIV medical care >12 months before baseline visit) to intervention or control conditions. The intervention condition addresses ART adherence barriers through medication reminders and adherence monitoring, tracking of select adherence-related behaviors (eg, alcohol and marijuana use), an interactive dashboard that displays the participant's adherence-related behaviors and provides tailored feedback, encouragement messages from other users, daily HIV/ART educational articles, and gamification features (eg, mini-games, points, badges) to increase motivation for behavior change and app engagement. The control condition features weekly phone-based notifications to encourage participants to view educational information in the control app. Follow-up assessments are administered at 13, 26, and 39 weeks for each arm.

The human factors plan was developed as a methodology to apply human factors from the conceptual design of the EPIC system to the functional verification conducted at the plant. An integral part of the Human Factors Plan was the Functional Verification Plan. Developed in parallel, this second plan and its resultant programs verified functional appropriateness of the SPDS display, NSSS displays, EOP displays, man-machine interfaces (MMI), and workstation designs. The functional verification process was performed at the hardware/software developer's factory and at the JAFNPP, following installation of the EPIC system. Because the EPIC system replaces existing control room equipment, it is important that human factors be applied in a systematic manner consistent with other control room displays and controls. To ensure that this goal was met, a human factors plan was developed

Prediction of proteins' secondary structure is one of the major steps in the generation of homology models. These models provide structural information which is used to design suitable ligands for potential medicinal targets. However, selecting a proper tool between multiple secondary structure prediction (SSP) options is challenging. The current study is an insight onto currently favored methods and tools, within various contexts. A systematic review was performed for a comprehensive access to recent (2013-2016) studies which used or recommended protein SSP tools. Three databases, Web of Science, PubMed and Scopus were systematically searched and 99 out of 209 studies were finally found eligible to extract data. Four categories of applications for 59 retrieved SSP tools were: (I) prediction of structural features of a given sequence, (II) evaluation of a method, (III) providing input for a new SSP method and (IV) integrating a SSP tool as a component for a program. PSIPRED was found to be the most popular tool in all four categories. JPred and tools utilizing PHD (Profile network from HeiDelberg) method occupied second and third places of popularity in categories I and II. JPred was only found in the two first categories, while PHD was present in three fields. This study provides a comprehensive insight about the recent usage of SSP tools which could be helpful for selecting a proper tool's choice.

Novel and delicate meanings, beautiful and innovative descriptions and lexical and semantic embellishments put this Mathnavi amongst the most important historical epics of Persian literature. Also, the presence of old and rare words, Turkish and Mongolian words and idioms prevalent in the Persian language have made this work a valuable source for lexicographers. The historical aspect of this work is also of significance. The correction of this work can open a new space for broader researches on Hatefi, the style of his works and the condition of his time.

Helicoverpa armigera is an important pest of cotton and other agricultural crops in the Old World. Its wide host range, high mobility and fecundity, and the ability to adapt and develop resistance against all common groups of insecticides used for its management have exacerbated its pest status. An understanding of the population genetic structure in H. armigera under Indian agricultural conditions will help ascertain gene flow patterns across different agricultural zones. This study inferred the population genetic structure of Indian H. armigera using five Exon-Primed Intron-Crossing (EPIC)-PCR markers. Nested alternative EPIC markers detected moderate null allele frequencies (4.3% to 9.4%) in loci used to infer population genetic structure but the apparently genome-wide heterozygote deficit suggests in-breeding or a Wahlund effect rather than a null allele effect. Population genetic analysis of the 26 populations suggested significant genetic differentiation within India but especially in cotton-feeding populations in the 2006-07 cropping season. In contrast, overall pair-wise F(ST) estimates from populations feeding on food crops indicated no significant population substructure irrespective of cropping seasons. A Baysian cluster analysis was used to assign the genetic make-up of individuals to likely membership of population clusters. Some evidence was found for four major clusters with individuals in two populations from cotton in one year (from two populations in northern India) showing especially high homogeneity. Taken as a whole, this study found evidence of population substructure at host crop, temporal and spatial levels in Indian H. armigera, without, however, a clear biological rationale for these structures being evident.

A Critique of the Application of Neighborhood Sustainability Assessment Tools in Urban Regeneration

Full Text Available Neighbourhood Sustainability Assessment Tools (NSA tools are fast becoming the principal framework for urban planners and developers for promoting urban sustainability. The majority of NSA tools promote a specific type of urban development that effectively excludes regeneration projects from the urban sustainability conversation. Given that the world’s megacities are mostly built, it is argued that it is essential that strategies for global sustainability consider that urban development is focussed internally to address existing, under-serviced communities in particular need of meaningful intervention and sustainable redevelopment frameworks. The paper uses existing knowledge on NSA tools to highlight the shortcomings of outcomes-based approaches to urban governance and builds the case that the technocratic “one-size-fits-all” approach adopted by many tools inadequately accounts for underlying institutional, social and economic arrangements that influence urban development, making them inappropriate for application in both planned and existing communities. The paper proposes that urban redevelopment strategies need to be derived from the urban realities of a particular place or context. Such strategies must be grounded in principles of urban governance, participatory action and an understanding of market dynamics. Without these collaborative procedural frameworks, urban regeneration projects will continue to inadequately transition towards more comprehensive sustainability.
