Aerosol and cloud sensing with the Lidar In-space Technology Experiment (LITE)
Winker, D. M.; McCormick, M. P.
1994-01-01
The Lidar In-space Technology Experiment (LITE) is a multi-wavelength backscatter lidar developed by NASA Langley Research Center to fly on the Space Shuttle. The LITE instrument is built around a three-wavelength ND:YAG laser and a 1-meter diameter telescope. The laser operates at 10 Hz and produces about 500 mJ per pulse at 1064 nm and 532 nm, and 150 mJ per pulse at 355 nm. The objective of the LITE program is to develop the engineering processes required for space lidar and to demonstrate applications of space-based lidar to remote sensing of the atmosphere. The LITE instrument was designed to study a wide range of cloud and aerosol phenomena. To this end, a comprehensive program of scientific investigations has been planned for the upcoming mission. Simulations of on-orbit performance show the instrument has sufficient sensitivity to detect even thin cirrus on a single-shot basis. Signal averaging provides the capability of measuring the height and structure of the planetary boundary layer, aerosols in the free troposphere, the stratospheric aerosol layer, and density profiles to an altitude of 40 km. The instrument has successfully completed a ground-test phase and is scheduled to fly on the Space Shuttle Discovery for a 9-day mission in September 1994.

Modal survey testing of the Lidar In-space Technology Experiment (LITE) - A Space Shuttle payload
Anderson, J. B.; Coleman, A. D.; Driskill, T. C.; Lindell, M. C.
This paper presents the results of the modal survey test of the Lidar In-space Technology Experiment (LITE), a Space Shuttle payload mounted in a Spacelab flight single pallet. The test was performed by the Dynamics Test Branch at Marshall Space Flight Center, AL and run in two phases. In the first phase, an unloaded orthogrid connected to the pallet with 52 tension struts was tested. This test included 73 measurement points in three directions. In the second phase, the pallet was integrated with mass simulators mounted on the flight support structure to represent the dynamics (weight and center of gravity) of the various components comprising the LITE experiment and instrumented at 213 points in 3 directions. The test article was suspended by an air bag system to simulate a free-free boundary condition. This paper presents the results obtained from the testing and analytical model correlation efforts. The effect of the suspension system on the test article is also discussed.

Project LITE - Light Inquiry Through Experiments
Brecher, K.
2004-12-01
Hands-on, inquiry-based, constructivist activity offers students a powerful way to explore, uncover and ultimately gain a feel for the nature of science. In order to make practicable a more genuine approach to learning astronomy, we have undertaken the development of hands-on (and eyes-on) materials that can be used in introductory undergraduate astronomy courses. These materials focus on light and optics. Over the past several years as part of Project LITE (Light Inquiry Through Experiments), we have developed a kit of optical materials that is integrated with a set of Java applets. The combined kit and software allows students to do actual experiments concerning geometrical optics, fluorescence, phosphorescence, polarization and other topics by making use of the photons that are emitted by their computer screens. We have also developed a suite of over 100 Flash applets that allow students to directly explore many aspects of visual perception. A major effort of the project concerns spectroscopy, since it is arguably the most important tool used by astronomers to disentangle the nature of the universe. It is also one of the most challenging subjects to teach in undergraduate astronomy courses. The spectroscopy component of Project LITE includes take-home laboratory materials and experiments that are integrated with web-based software. We have also developed a novel quantitative handheld binocular spectrometer (patent pending). Our major spectroscopic software is called the Spectrum Explorer (SPEX). It allows students to create, manipulate and explore all types of spectra including blackbody, power law, emission and absorption. We are now extending the SPEX capabilities to help students gain easy access to the astronomical spectra included in the NVO databases. All of the Project LITE software can be found http://lite.bu.edu. Project LITE is supported by Grant #DUE-0125992 from the NSF Division of Undergraduate Education.

Experience with the gLite workload management system in ATLAS Monte Carlo production on LCG
International Nuclear Information System (INIS)
Campana, S; Sciaba, A; Rebatto, D
2008-01-01
The ATLAS experiment has been running continuous simulated events production since more than two years. A considerable fraction of the jobs is daily submitted and handled via the gLite Workload Management System, which overcomes several limitations of the previous LCG Resource Broker. The gLite WMS has been tested very intensively for the LHC experiments use cases for more than six months, both in terms of performance and reliability. The tests were carried out by the LCG Experiment Integration Support team (in close contact with the experiments) together with the EGEE integration and certification team and the gLite middleware developers. A pragmatic iterative and interactive approach allowed a very quick rollout of fixes and their rapid deployment, together with new functionalities, for the ATLAS production activities. The same approach is being adopted for other middleware components like the gLite and CREAM Computing Elements. In this contribution we will summarize the learning from the gLite WMS testing activity, pointing out the most important achievements and the open issues. In addition, we will present the current situation of the ATLAS simulated event production activity on the EGEE infrastructure based on the gLite WMS, showing the main improvements and benefits from the new middleware. Finally, the gLite WMS is being used by many other VOs, including the LHC experiments. In particular, some statistics will be shown on the CMS experience running WMS user analysis via the WMS

This report describes the development and testing of a novel system, the Greenhouse gas Laser Imaging Tomography Experiment (GreenLITE), for Monitoring, Reporting and Verification (MRV) of CO2 at Geological Carbon Storage (GCS) sites. The system consists of a pair of laser based transceivers, a number of retroreflectors, and a set of cloud based data processing, storage and dissemination tools, which enable 2-D mapping of the CO2 in near real time. A system was built, tested locally in New Haven, Indiana, and then deployed to the Zero Emissions Research and Technology (ZERT) facility in Bozeman, MT. Testing at ZERT demonstrated the ability of the GreenLITE system to identify and map small underground leaks, in the presence of other biological sources and with widely varying background concentrations. The system was then ruggedized and tested at the Harris test site in New Haven, IN, during winter time while exposed to temperatures as low as -15 °CºC. Additional testing was conducted using simulated concentration enhancements to validate the 2-D retrieval accuracy. This test resulted in a high confidence in the reconstruction ability to identify sources to tens of meters resolution in this configuration. Finally, the system was deployed for a period of approximately 6 months to an active industrial site, Illinois Basin – Decatur Project (IBDP), where >1M metric tons of CO2 had been injected into an underground sandstone basin. The main objective of this final deployment was to demonstrate autonomous operation over a wide range of environmental conditions with very little human interaction, and to demonstrate the feasibility of the system for long term deployment in a GCS environment.

Project LITE (Light Inquiry Through Experiments) is a materials, software, and curriculum development project. It focuses on light, optics, color and visual perception. According to two recent surveys of college astronomy faculty members, these are among the topics most often included in the large introductory astronomy courses. The project has aimed largely at the design and implementation of hands-on experiences for students. However, it has also included the development of lecture demonstrations that employ novel light sources and materials. In this presentation, we will show some of our new lecture demonstrations concerning geometrical and physical optics, fluorescence, phosphorescence and polarization. We have developed over 200 Flash and Java applets that can be used either by teachers in lecture settings or by students at home. They are all posted on the web at http://lite.bu.edu. For either purpose they can be downloaded directly to the user's computer or run off line. In lecture demonstrations, some of these applets can be used to control the light emitted by video projectors to produce physical effects in materials (e.g. fluorescence). Other applets can be used, for example, to demonstrate that the human percept of color does not have a simple relationship with the physical frequency of the stimulating source of light. Project LITE is supported by Grant #DUE-0125992 from the NSF Division of Undergraduate Education.

Longitudinal Ionospheric Variability Observed by LITES on the ISS
Stephan, A. W.; Finn, S. C.; Cook, T.; Geddes, G.; Chakrabarti, S.; Budzien, S. A.
2017-12-01
The Limb-Imaging Ionospheric and Thermospheric Extreme-Ultraviolet Spectrograph (LITES) is an imaging spectrograph designed to measure altitude profiles (150-350 km) of extreme- and far-ultraviolet airglow emissions that originate from photochemical processes in the ionosphere and thermosphere. During the daytime, LITES observes the bright O+ 83.4 nm emission from which the ionospheric profile can be inferred. At night, recombination emissions at 91.1 and 135.6 nm provide a direct measure of the electron content along the line of sight. LITES was launched and installed on the International Space Station (ISS) in late February 2017 where it has been operating along with the highly complementary GPS Radio Occultation and Ultraviolet Photometry - Colocated (GROUP-C) experiment. We will present some of the first observations from LITES in April 2017 that show longitudinal patterns in ionospheric density and the daily variability in those patterns. LITES vertical imaging from a vantage point near 410 km enables a particularly unique perspective on the altitude of the ionospheric peak density at night that can complement and inform other ground- and space-based measurements, and track the longitude-altitude variability that is reflective of changes in equatorial electrodynamics.

RGLite, an interface between ROOT and gLite-proof on the grid
International Nuclear Information System (INIS)
Malzacher, P; Manafov, A; Schwarz, K
2008-01-01
Using the gLitePROOF package it is possible to perform PROOF-based distributed data analysis on the gLite Grid. The LHC experiments managed to run globally distributed Monte Carlo productions on the Grid, now the development of tools for data analysis is in the foreground. To grant access interfaces must be provided. The ROOT/PROOF framework is used as a starting point. Using abstract ROOT classes (TGrid, ...) interfaces can be implemented, via which Grid access from ROOT can be accomplished. A concrete implementation exists for the ALICE Grid environment AliEn. Within the D-Grid project an interface to the common Grid middleware of all LHC experiments, gLite, has been created. Therefore it is possible to query Grid File Catalogues from ROOT for the location of the data to be analysed. Grid jobs can be submitted into a gLite based Grid. The status of the jobs can be asked for, and their results can be obtained

The Limb-Imaging Ionospheric and Thermospheric Extreme-ultraviolet Spectrograph (LITES) was launched as part of the Space Test Program Houston #5 (STP-H5) payload aboard a commercial resupply flight on February 19, 2017 and was subsequently installed on the International Space Station (ISS). LITES is an imaging spectrograph that spans the 60 - 140 nm wavelength range at 1 nm spectral resolution and samples tangent altitudes 150 - 350 km with 0.2° angular resolution. LITES, in combination with the GPS Radio Occultation and Ultraviolet Photometry - Colocated (GROUP-C) experiment, which includes a GPS receiver and a nadir viewing 135.6 nm photometer, jointly collect new information on the thermosphere and the ionosphere using simultaneous UV and radio emissions. LITES, which uses standard stars to perform in-flight calibration, observes altitude profiles of day and night airglow emissions that are being used to infer thermospheric and ionospheric density profiles. Furthermore, due to the inclination of the ISS, LITES has also observed auroral spectrum and their altitude and spatial variations. Finally, geomagnetic storm effects on its UV emissions can be used to remotely sense their effects on the upper atmospheric morphology. These ISS observations,which are complement to the upcoming ICON and GOLD NASA missions, are focused on ionosphere-atmosphere coupling and global-scale atmospheric response to space weather observed from higher altitudes . We will present an overview of the LITES instrument, some early results from the first few months of operations. We will also summarize the advantages in calibration and validation activities that are possible through space-based LITES, GROUP-C and stellar measurements and simultaneous ground-based optical and radar observations.

The CMS experiment at LHC started using the Resource Broker (by the EDG and LCG projects) to submit Monte Carlo production and analysis jobs to distributed computing resources of the WLCG infrastructure over 6 years ago. Since 2006 the gLite Workload Management System (WMS) and Logging and Bookkeeping (LB) are used. The interaction with the gLite-WMS/LB happens through the CMS production and analysis frameworks, respectively ProdAgent and CRAB, through a common component, BOSSLite. The important improvements recently made in the gLite-WMS/LB as well as in the CMS tools and the intrinsic independence of different WMS/LB instances allow CMS to reach the stability and scalability needed for LHC operations. In particular the use of a multi-threaded approach in BOSSLite allowed to increase the scalability of the systems significantly. In this work we present the operational set up of CMS production and analysis based on the gLite-WMS and the performances obtained in the past data challenges and in the daily Monte Carlo productions and user analysis usage in the experiment.

Vega-Lite: A Grammar of Interactive Graphics.
Satyanarayan, Arvind; Moritz, Dominik; Wongsuphasawat, Kanit; Heer, Jeffrey
2017-01-01
We present Vega-Lite, a high-level grammar that enables rapid specification of interactive data visualizations. Vega-Lite combines a traditional grammar of graphics, providing visual encoding rules and a composition algebra for layered and multi-view displays, with a novel grammar of interaction. Users specify interactive semantics by composing selections. In Vega-Lite, a selection is an abstraction that defines input event processing, points of interest, and a predicate function for inclusion testing. Selections parameterize visual encodings by serving as input data, defining scale extents, or by driving conditional logic. The Vega-Lite compiler automatically synthesizes requisite data flow and event handling logic, which users can override for further customization. In contrast to existing reactive specifications, Vega-Lite selections decompose an interaction design into concise, enumerable semantic units. We evaluate Vega-Lite through a range of examples, demonstrating succinct specification of both customized interaction methods and common techniques such as panning, zooming, and linked selection.

Expanding Scales and Applications for 2D Spatial Mapping of CO2 using GreenLITE
Erxleben, W. H.; Dobler, J. T.; Zaccheo, T. S.; Blume, N.; Braun, M.
2015-12-01
The Greenhouse gas Laser Imaging Tomography Experiment (GreenLITE) system is a new measurement approach originally developed under a cooperative agreement with the Department of Energy (DOE) National Energy Technology Laboratory (NETL), Atmospheric Environmental Sciences (AER) and Exelis Inc. (now part of Harris Corp.). The original system design provides 24/7 monitoring of Ground Carbon Storage (GCS) sites, in order to help ensure worker safety and verify 99% containment. The first generation was designed to cover up to 1km2 area, and employs the Exelis Continuous Wave (CW) Intensity Modulated (IM) approach to measure differential transmission. A pair of scanning transceivers was built and combined with a series of retro reflectors, and a local weather station to provide the information required for producing estimates of the atmospheric CO2 concentration over a number of overlapping lines-of-site. The information from the transceivers, and weather station, are sent remotely to a web-based processing and storage tool, which in-turn uses the data to generate estimates of the 2D spatial distribution over the area of coverage and disseminate that information near real-time via a secure web interface. Recently, in 2015, Exelis and AER have invested in the expansion of the GreenLITE transceiver system to 5 km range, enabling areas up to 25 km2 to be evaluated with this technology, and opening new possibilities for applications such as urban scale monitoring. The 5 km system is being tested in conjunction with the National Institute of Standards and Technology at the Boulder Atmospheric Observatory in August of this year. This talk will review the initial GreenLITE system, testing and deployment of that system, and the more recent development, expansion and testing of the 5 km system.

Selvarajan, Shoba [Iowa State Univ., Ames, IA (United States)
2002-01-01
The goal of this thesis is to develop a new Channel Interface device for the MPICH Implementation of the MPI (Message Passing Interface) standard using MP_Lite. MP_Lite is a lightweight message-passing library that is not a full MPI implementation, but offers high performance MPICH (Message Passing Interface CHameleon) is a full implementation of the MPI standard that has the p4 library as the underlying communication device for TCP/IP networks. By integrating MP_Lite as a Channel Interface device in MPICH, a parallel programmer can utilize the full MPI implementation of MPICH as well as the high bandwidth offered by MP_Lite. There are several layers in the MPICH library where one can tie a new device. The Channel Interface is the lowest layer that requires very few functions to add a new device. By attaching MP_Lite to MPICH at the lowest level, the Channel Interface, almost all of the performance of the MP_Lite library can be delivered to the applications using MPICH. MP_Lite can be implemented either as a blocking or a non-blocking Channel Interface device. The performance was measured on two separate test clusters, the PC and the Alpha miniclusters, having Gigabit Ethernet connections. The PC cluster has two 1.8 GHz Pentium 4 PCs and the Alpha cluster has two 500 MHz Compaq DS20 workstations. Different network interface cards like Netgear, TrendNet and SysKonnect Gigabit Ethernet cards were used for the measurements. Both the blocking and non-blocking MPICH-MP_Lite Channel Interface devices perform close to raw TCP, whereas a performance loss of 25-30% is seen in the MPICH-p4 Channel Interface device for larger messages. The superior performance offered by the MPICH-MP_Lite device compared to the MPICH-p4 device can be easily seen on the SysKonnect cards using jumbo frames. The throughput curve also improves considerably by increasing the Eager/Rendezvous threshold.

The short form of impact of weight on quality of life (IWQOL)-Lite is a 31-item, self-report, obesity-specific measure of health-related quality of life (HRQOL) that consists of a total score and scores on each of five scales--physical function, self-esteem, sexual life, public distress, and work--and that exhibits strong psychometric properties. This study was undertaken in order to assess test-retest reliability and discriminant validity in a heterogeneous sample of individuals not in treatment. Individuals were recruited from the community to complete questionnaires that included the IWQOL-Lite, SF-36, Rosenberg self-esteem (RSE) scale, Marlowe-Crowne social desirability scale, global ratings of quality of life, and sexual functioning and public distress ratings. Persons currently enrolled in weight loss programs or with a body mass index (BMI) of less than 18.5 were dropped from the analyses, leaving 341 females and 153 males for analysis, with an average BMI of 27.4. For test-retest reliability, 112 participants completed the IWQOL-Lite again. ANOVA revealed significant main effects for BMI for all IWQOL-Lite scales and total score. Females showed greater impairment than males on all scales except public distress. Internal consistency ranged from 0.816 to 0.944 for IWQOL-Lite scales and was 0.958 for total score. Test-retest reliability ranged from 0.814 to 0.877 for scales and was 0.937 for total score. Internal consistency and test-retest results for overweight/obese subjects were similar to those obtained for the total sample. There was strong evidence for convergent and discriminant validity of the IWQOL-Lite in overweight/obese subjects. As in previous studies conducted on treatment-seeking obese persons, the IWQOL-Lite appears to be a reliable and valid measure of obesity-specific quality of life in overweight/obese persons not seeking treatment.

Implementation of MP_Lite for the VI Architecture
Energy Technology Data Exchange (ETDEWEB)
Chen, Weiyi [Iowa State Univ., Ames, IA (United States)
2001-01-01
MP_Lite is a light weight message-passing library designed to deliver the maximum performance to applications in a portable and user friendly manner. The Virtual Interface (VI) architecture is a user-level communication protocol that bypasses the operating system to provide much better performance than traditional network architectures. By combining the high efficiency of MP_Lite and high performance of the VI architecture, they are able to implement a high performance message-passing library that has much lower latency and better throughput. The design and implementation of MP_Lite for M-VIA, which is a modular implementation of the VI architecture on Linux, is discussed in this thesis. By using the eager protocol for sending short messages, MP_Lite M-VIA has much lower latency on both Fast Ethernet and Gigabit Ethernet. The handshake protocol and RDMA mechanism provides double the throughput that MPICH can deliver for long messages. MP_Lite M-VIA also has the ability to channel-bonding multiple network interface cards to increase the potential bandwidth between nodes. Using multiple Fast Ethernet cards can double or even triple the maximum throughput without increasing the cost of a PC cluster greatly.

ARCIMBOLDO_LITE: single-workstation implementation and use.
Sammito, Massimo; Millán, Claudia; Frieske, Dawid; Rodríguez-Freire, Eloy; Borges, Rafael J; Usón, Isabel
2015-09-01
ARCIMBOLDO solves the phase problem at resolutions of around 2 Å or better through massive combination of small fragments and density modification. For complex structures, this imposes a need for a powerful grid where calculations can be distributed, but for structures with up to 200 amino acids in the asymmetric unit a single workstation may suffice. The use and performance of the single-workstation implementation, ARCIMBOLDO_LITE, on a pool of test structures with 40-120 amino acids and resolutions between 0.54 and 2.2 Å is described. Inbuilt polyalanine helices and iron cofactors are used as search fragments. ARCIMBOLDO_BORGES can also run on a single workstation to solve structures in this test set using precomputed libraries of local folds. The results of this study have been incorporated into an automated, resolution- and hardware-dependent parameterization. ARCIMBOLDO has been thoroughly rewritten and three binaries are now available: ARCIMBOLDO_LITE, ARCIMBOLDO_SHREDDER and ARCIMBOLDO_BORGES. The programs and libraries can be downloaded from http://chango.ibmb.csic.es/ARCIMBOLDO_LITE.

LiteBIRD [Lite (Light) satellite for the studies of B-mode polarization and Inflation from cosmic background Radiation Detection] is a small satellite to map the polarization of the cosmic microwave background (CMB) radiation over the full sky at large angular scales with unprecedented precision. Cosmological inflation, which is the leading hypothesis to resolve the problems in the Big Bang theory, predicts that primordial gravitational waves were created during the inflationary era. Measurements of polarization of the CMB radiation are known as the best probe to detect the primordial gravitational waves. The LiteBIRD working group is authorized by the Japanese Steering Committee for Space Science (SCSS) and is supported by JAXA. It has more than 50 members from Japan, USA and Canada. The scientific objective of LiteBIRD is to test all the representative inflation models that satisfy single-field slow-roll conditions and lie in the large-field regime. To this end, the requirement on the precision of the tensor-to-scalar ratio, r, at LiteBIRD is equal to or less than 0.001. Our baseline design adopts an array of multi-chroic superconducting polarimeters that are read out with high multiplexing factors in the frequency domain for a compact focal plane. The required sensitivity of 1.8μKarcmin is achieved with 2000 TES bolometers at 100mK. The cryogenic system is based on the Stirling/JT technology developed for SPICA, and the continuous ADR system shares the design with future X-ray satellites.

Hot ion buildup and lifetime in LITE. Final report
International Nuclear Information System (INIS)
1978-09-01
An experimental investigation of hot ion buildup and lifetime in a small scale mirror device (LITE) is described. Hot ions were produced by 27 kV neutral beam injection into laser produced LiH plasmas and H plasmas produced by a washer gun. Hot H ion (12 kV) densities of approx. = 10 12 cm -3 were produced with the LiH target plasmas and densities an order of magnitude lower were produced with the washer gun target plasmas. Hot ion dominant plasmas were not achieved in LITE. The experimental measurements and subsequent analysis using numerical models of the plasma buildup indicate that in small, unshielded mirror plasmas, careful control must be maintained over the transient background gas density in the vicinity of the plasma surface. The hot ion lifetime in LITE was set by the transient cold neutral background resulting from the washer gun of reflux from the target plasma striking the adjacent surfaces

2003-08-01
Este trabalho centra-se em atividades na fase de pré-lançamento do satélite COROT, da agência espacial francesa (CNES), a ser lançado em 2005. O satélite será dedicado à sismologia estelar e à procura de exoplanetas. Nosso programa de trabalho centra-se em dois pontos principais: (1) efetuar uma procura detalhada nos campos COROT de alvos astrofísicos de especial interesse; (2) participar das análises espectroscópicas prévias de alvos selecionados para determinação de parâmetros físicos das estrelas com a maior precisão possível. Na presente etapa, priorizou-se o primeiro ponto do projeto. Foi feito um levantamento geral dos objetos astrofísicos encontrados nos dois campos de observação, centrados em 06H50M e 18H50M, com raios de 10 minutos. Concluiu-se que as estrelas B-Be deverão ser observadas no campo sismológico, enquanto que as anãs brancas deverão sê-lo no campo exoplanetário. Objetos a serem observados foram escolhidos de forma a estarem próximos de alvos principais dos programas centrais do satélite. Paralelamente, estudos e pesquisas bibliográficas foram feitos para compreender os assuntos de interesse principal, ou seja, as pulsações não-radiais de estrelas Ob-Be

Automation and hypermedia technology applications
Jupin, Joseph H.; Ng, Edward W.; James, Mark L.
1993-01-01
This paper represents a progress report on HyLite (Hypermedia Library technology): a research and development activity to produce a versatile system as part of NASA's technology thrusts in automation, information sciences, and communications. HyLite can be used as a system or tool to facilitate the creation and maintenance of large distributed electronic libraries. The contents of such a library may be software components, hardware parts or designs, scientific data sets or databases, configuration management information, etc. Proliferation of computer use has made the diversity and quantity of information too large for any single user to sort, process, and utilize effectively. In response to this information deluge, we have created HyLite to enable the user to process relevant information into a more efficient organization for presentation, retrieval, and readability. To accomplish this end, we have incorporated various AI techniques into the HyLite hypermedia engine to facilitate parameters and properties of the system. The proposed techniques include intelligent searching tools for the libraries, intelligent retrievals, and navigational assistance based on user histories. HyLite itself is based on an earlier project, the Encyclopedia of Software Components (ESC) which used hypermedia to facilitate and encourage software reuse.

Medical Data Manager an Interface between PACS and the gLite Data Management System
Montagnat, Johan; Texier, Romain; Nienartowicz, Krzysztof; Baud, Jean-Philippe
2008-01-01
The medical imaging community uses the DICOM image format and protocol to store and exchange data. The Medical Data Manager (MDM) is an interface between DICOM compliant systems such as PACS and the EGEE Data Management System. It opens hospital imaging networks to the world scale Grid while protecting sensitive medical data. It can be accessed transparently from any gLite service. It is an important milestone towards adoption of Grid technologies in the medical imaging community. Hospitals continuously produce tremendous amounts of image data that is managed by local PACS (Picture Archiving and Communication Systems). These systems are often limited to a local network access although the community experiences a growing interest for data sharing and remote processing. Indeed, patient data is often spread out different medical data acquisition centers. Furthermore, researchers in the area often need to analyze large populations whose data can be gathered through federations of PACS. Opening PACS to the outer I...

M2Lite: An Open-source, Light-weight, Pluggable and Fast Proteome Discoverer MSF to mzIdentML Tool.
Aiyetan, Paul; Zhang, Bai; Chen, Lily; Zhang, Zhen; Zhang, Hui
2014-04-28
Proteome Discoverer is one of many tools used for protein database search and peptide to spectrum assignment in mass spectrometry-based proteomics. However, the inadequacy of conversion tools makes it challenging to compare and integrate its results to those of other analytical tools. Here we present M2Lite, an open-source, light-weight, easily pluggable and fast conversion tool. M2Lite converts proteome discoverer derived MSF files to the proteomics community defined standard - the mzIdentML file format. M2Lite's source code is available as open-source at https://bitbucket.org/paiyetan/m2lite/src and its compiled binaries and documentation can be freely downloaded at https://bitbucket.org/paiyetan/m2lite/downloads.

The gLite Workload Management System (WMS) is a collection of components that provide the service responsible for distributing and managing tasks across computing and storage resources available on a Grid. The WMS basically receives requests of job execution from a client, finds the required appropriate resources, then dispatches and follows the jobs until completion, handling failure whenever possible. Other than single batch-like jobs, compound job types handled by the WMS are Directed Acyclic Graphs (a set of jobs where the input/output/execution of one of more jobs may depend on one or more other jobs), Parametric Jobs (multiple jobs with one parametrized description), and Collections (multiple jobs with a common description). Jobs are described via a flexible, high-level Job Definition Language (JDL). New functionality was recently added to the system (use of Service Discovery for obtaining new service endpoints to be contacted, automatic sandbox files archival/compression and sharing, support for bulk-submission and bulk-matchmaking). Intensive testing and troubleshooting allowed to dramatically increase both job submission rate and service stability. Future developments of the gLite WMS will be focused on reducing external software dependency, improving portability, robustness and usability

The gLite Workload Management System represents a key entry point to high-end services available on a Grid. Being designed as part of the european Grid within the six years long EU-funded EGEE project, now at its third phase, the WMS is meant to provide reliable and efficient distribution and management of end-user requests. This service basically translates user requirements and preferences into specific operations and decisions - dictated by the general status of all other Grid services - while taking responsibility to bring requests to successful completion. The WMS has become a reference implementation of the 'early binding' approach to meta-scheduling as a neat, Grid-aware solution, able to optimise resource access and to satisfy requests for computation together with data. Several added value features are provided for job submission, different job types are supported from simple batch to a variety of compounds. In this paper we outline what has been achieved to provide adequate workload and management components, suitable to be deployed in a production-quality Grid, while covering the design and development of the gLite WMS and focusing on the most recently achieved results.

The gLite File Transfer Service
Badino, Paolo; Casey, J; Frohner, A; Kunszt, Peter Z; McCance, G
2006-01-01
In this paper we describe the architecture and implementation of the gLite File Transfer Service (FTS) and list the most basic deployment scenarios. The FTS is addressing the need to manage massive wide-area data transfers on dedicated network channels while allowing the involved sites and users to manage their policies. The FTS manages the transfers in a robust way, allowing for an optimized high throughput between storage systems. The FTS can be used to perform the LHC Tier-0 to Tier-1 data transfer as well as the Tier-1 to Tier-2 data distribution and collection. The storage system peculiarities can be taken into account by fine-tuning the parameters of the FTS managing a particular channel. All the manageability related features as well as the interaction with other components that form part of the overall service are described as well. The FTS is also extensible so that particular user groups or experiment frameworks can customize its behavior both for pre- and post-transfer tasks. The FTS has been desig...

Moshir, Mehrdad; Murphy, David W.; Milman, Mark H.; Meier, David L.
2010-01-01
The SIM Lite Astrometric Observatory will be the first space-based Michelson interferometer operating in the visible wavelength, with the ability to perform ultra-high precision astrometric measurements on distant celestial objects. SIM Lite data will address in a fundamental way questions such as characterization of Earth-mass planets around nearby stars. To accomplish these goals it is necessary to rely on a model-based systems engineering approach - much more so than most other space missions. This paper will describe in further detail the components of this end-to-end performance model, called "SIM-sim", and show how it has helped the systems engineering process.

Te/C nanocomposites for Li-Te Secondary Batteries
Seo, Jeong-Uk; Seong, Gun-Kyu; Park, Cheol-Min
2015-01-01
New battery systems having high energy density are actively being researched in order to satisfy the rapidly developing market for longer-lasting mobile electronics and hybrid electric vehicles. Here, we report a new Li-Te secondary battery system with a redox potential of ~1.7 V (vs. Li+/Li) adapted on a Li metal anode and an advanced Te/C nanocomposite cathode. Using a simple concept of transforming TeO2 into nanocrystalline Te by mechanical reduction, we designed an advanced, mechanically reduced Te/C nanocomposite electrode material with high energy density (initial discharge/charge: 1088/740 mA h cm-3), excellent cyclability (ca. 705 mA h cm-3 over 100 cycles), and fast rate capability (ca. 550 mA h cm-3 at 5C rate). The mechanically reduced Te/C nanocomposite electrodes were found to be suitable for use as either the cathode in Li-Te secondary batteries or a high-potential anode in rechargeable Li-ion batteries. We firmly believe that the mechanically reduced Te/C nanocomposite constitutes a breakthrough for the realization and mass production of excellent energy storage systems.

There is an urgent need to capture metadata on the rapidly growing number of genomic, metagenomic and related sequences, such as 16S ribosomal genes. This need is a major focus within the Genomic Standards Consortium (GSC), and Habitat is a key metadata descriptor in the proposed 'Minimum Information about a Genome Sequence' (MIGS) specification. The goal of the work described here is to provide a light-weight, easy-to-use (small) set of terms ('Habitat-Lite') that captures high-level information about habitat while preserving a mapping to the recently launched Environment Ontology (EnvO). Our motivation for building Habitat-Lite is to meet the needs of multiple users, such as annotators curating these data, database providers hosting the data, and biologists and bioinformaticians alike who need to search and employ such data in comparative analyses. Here, we report a case study based on semi-automated identification of terms from GenBank and GOLD. We estimate that the terms in the initial version of Habitat-Lite would provide useful labels for over 60% of the kinds of information found in the GenBank isolation-source field, and around 85% of the terms in the GOLD habitat field. We present a revised version of Habitat-Lite and invite the community's feedback on its further development in order to provide a minimum list of terms to capture high-level habitat information and to provide classification bins needed for future studies.

Magnetic confinement of laser produced LiH plasma in LITE
International Nuclear Information System (INIS)
Ard, W.B.; Stufflebeam, J.H.; Tomlinson, R.G.
1976-01-01
In the LITE experiment, a hot, dense plasma produced by laser heating of an approximately 100 μ dia LiH particle is used to fill a minimum-B baseball coil mirror magnetic containment field. The confined laser produced plasma subsequently serves as the target for an energetic neutral hydrogen beam in experiments to investigate the target plasma buildup approach for creating and sustaining an equilibrium, steady state mirror fusion plasma. In the experiments, the LiH particle is positioned in vacuum at the laser beam focus by a feedback particle suspension system and heated by two sided irradiation with the focused dual beam, 50 j, 7 nsec output of a Q-switched Nd-glass laser. The energy density of the laser produced plasma is initially much greater than that of the surrounding magnetic field and the plasma expands, converting its internal energy into expansion kinetic energy and displacement of the magnetic field. As the energy density falls below that of the magnetic field, the expansion is stopped and the plasma becomes trapped, making the transition to a low beta, mirror confined plasma. This report is concerned with the properties and behavior of the plasma in the confinement stage

Highlights: • Verification of the SuperMC Monte Carlo transport code with ITER C-Lite model. • The modeling of the ITER C-Lite model using the latest SuperMC/MCAM. • All the calculated quantities are consistent with MCNP well. • Efficient variance reduction methods are adopted to accelerate the calculation. - Abstract: In pursit of accurate and high fidelity simulation, the reference model of ITER is becoming more and more detailed and complicated. Due to the complexity in geometry and the thick shielding of the reference model, the accurate modeling and precise simulaion of fusion neutronics are very challenging. Facing these difficulties, SuperMC, the Monte Carlo simulation software system developed by the FDS Team, has optimized its CAD interface for the automatic converting of more complicated models and increased its calculation efficiency with advanced variance reduction methods To demonstrate its capabilites of automatic modeling, neutron/photon coupled simulation and visual analysis for the ITER facility, numerical benchmarks using the ITER C-Lite neutronic model were performed. The nuclear heating in divertor and inboard toroidal field (TF) coils and a global neutron flux map were evaluated. All the calculated nuclear heating is compared with the results of the MCNP code and good consistencies between the two codes is shown. Using the global variance reduction methods in SuperMC, the average speed-up is 292 times for the calculation of inboard TF coils nuclear heating, and 91 times for the calculation of global flux map, compared with the analog run. These tests have shown that SuperMC is suitable for the design and analysis of ITER facility.

Visando isto, o objetivo do trabalho foi analisar a aplicabilidade e os limites de detecção na identificação de alvos naturais em diferentes imagens de satélites. A área de estudo está localizada no Estado de São Paulo dentro do Município de Onda Verde, os alvos naturais foram selecionados a partir de análises realizadas nas imagens e visita desses pontos em campo. Foram escolhidas áreas que apresentaram bom contraste com o entorno e fácil localização nas imagens de satélite. Para o processamento digital de imagem foi utilizado o software livre gvSIG. Neste estudo foram empregados dados de satélites de média resolução espacial como Landsat-5, CBERS-2B e IRS-P6, disponíveis na base de dados de domínio público do INPE (Instituto Nacional de Pesquisas Espaciais e imagens de alta resolução espacial dos satélites RapidEye e WorldView-2. Nos sensores de média resolução espacial, as menores resoluções espaciais dos sensores TM e LISS-3, não impediram a visualização dos alvos espectrais analisados, visto que, no CCD que possui uma maior resolução espacial, não foi possível a identificação dos alvos escolhidos. As imagens de alta resolução espacial RapidEye e WorldView apresentaram grande riqueza de detalhamento para a cobertura do solo, a isto atrela-se a alta resolução radiométrica desses satélites.

LiteNet: Lightweight Neural Network for Detecting Arrhythmias at Resource-Constrained Mobile Devices
Directory of Open Access Journals (Sweden)
Ziyang He
2018-04-01
Full Text Available By running applications and services closer to the user, edge processing provides many advantages, such as short response time and reduced network traffic. Deep-learning based algorithms provide significantly better performances than traditional algorithms in many fields but demand more resources, such as higher computational power and more memory. Hence, designing deep learning algorithms that are more suitable for resource-constrained mobile devices is vital. In this paper, we build a lightweight neural network, termed LiteNet which uses a deep learning algorithm design to diagnose arrhythmias, as an example to show how we design deep learning schemes for resource-constrained mobile devices. Compare to other deep learning models with an equivalent accuracy, LiteNet has several advantages. It requires less memory, incurs lower computational cost, and is more feasible for deployment on resource-constrained mobile devices. It can be trained faster than other neural network algorithms and requires less communication across different processing units during distributed training. It uses filters of heterogeneous size in a convolutional layer, which contributes to the generation of various feature maps. The algorithm was tested using the MIT-BIH electrocardiogram (ECG arrhythmia database; the results showed that LiteNet outperforms comparable schemes in diagnosing arrhythmias, and in its feasibility for use at the mobile devices.

It can be trained faster than other neural network algorithms and requires less communication across different processing units during distributed training. It uses filters of heterogeneous size in a convolutional layer, which contributes to the generation of various feature maps. The algorithm was tested using the MIT-BIH electrocardiogram (ECG) arrhythmia database; the results showed that LiteNet outperforms comparable schemes in diagnosing arrhythmias, and in its feasibility for use at the mobile devices.

The AnnoLite and AnnoLyze programs for comparative annotation of protein structures
Directory of Open Access Journals (Sweden)
Dopazo Joaquín
2007-05-01
Full Text Available Abstract Background Advances in structural biology, including structural genomics, have resulted in a rapid increase in the number of experimentally determined protein structures. However, about half of the structures deposited by the structural genomics consortia have little or no information about their biological function. Therefore, there is a need for tools for automatically and comprehensively annotating the function of protein structures. We aim to provide such tools by applying comparative protein structure annotation that relies on detectable relationships between protein structures to transfer functional annotations. Here we introduce two programs, AnnoLite and AnnoLyze, which use the structural alignments deposited in the DBAli database. Description AnnoLite predicts the SCOP, CATH, EC, InterPro, PfamA, and GO terms with an average sensitivity of ~90% and average precision of ~80%. AnnoLyze predicts ligand binding site and domain interaction patches with an average sensitivity of ~70% and average precision of ~30%, correctly localizing binding sites for small molecules in ~95% of its predictions. Conclusion The AnnoLite and AnnoLyze programs for comparative annotation of protein structures can reliably and automatically annotate new protein structures. The programs are fully accessible via the Internet as part of the DBAli suite of tools at http://salilab.org/DBAli/.

In this work we describe some aspects of the dynamics of the mean-motion resonances. Emphasis to the case of resonances between regular satellites of the giant planets will be given, even so some aspects of the physics of the resonances in extra-solar planetary systems are also briefly treated. The role of the resonances in satellites systems is discussed through examples, showing how certain resonances, and its relations with the tidal dissipation effects, can be the key of the explanation of some phenomena still not explained in the Solar System. Amongst some examples we highlight the problem of the resurfacing of Enceladus, the existence of active volcanoes in Io, and the possible existence of the subsurface ocean in Europe. This work has as objective the divulgation of some topics in Celestial Mechanics and Planetary Sciences for an undergraduate public in exact sciences, as Astronomy and Physics, and not their detailed description. Neste trabalho descrevemos alguns aspectos da dinâmica de ressonâncias de movimentos médios. Será dada ênfase maior ao caso de ressonâncias entre satélites regulares dos planetas gigantes, embora alguns aspectos da física das ressonâncias em sistemas planetários extra-solares também sejam discutidos brevemente. A importância do estudo de ressonâncias em sistemas de satélites é discutida mais detalhadamente através de exemplos, mostrando como certas ressonâncias e suas relações com efeitos de dissipação de maré podem ser a chave de parte da explicação de alguns fenômenos ainda não explicados no Sistema Solar. Dentre vários exemplos destacamos o problema da remodelagem da superfície do satélite Enceladus, a existência de vulcões ativos em Io, e a possível existência do oceano subterrâneo em Europa. Este trabalho tem como objetivo a divulgação de alguns tópicos de Mecânica Celeste e Planetologia para um público de nível de graduação em disciplinas na área de exatas, em especial Astronomia e F

Full Text Available Resumen: El objetivo de este artÃculo es modelar, analizar y controlar una constelación de cinco satélites, situados en los puntos de Lagrange del sistema Tierra â Luna. El modelo se ha desarrollado incluyendo efectos complejos no considerados habitualmente, como el viento solar, la no esfericidad de los planetas y la deriva de la órbita lunar, para hacerlo más realista. Sobre los satélites se ejerce una propulsión continua, calculada por medio de controladores tipo PD, tanto convencionales como borrosos, y cuya finalidad es situar y mantener a cada satélite en su punto de Lagrange frente a las inestabilidades y derivas inherentes al sistema. El sistema completo se ha implementado en el lenguaje de modelado Modelica, para el que se han creado una serie de elementos aeroespaciales, y las simulaciones se han desarrollado con el software Dymola. Tanto con los controladores clásicos como con los borrosos se han obtenido muy buenos resultados.

Full Text Available This paper is innovating the theory of elités in the way it was configured by the Central and Eastern European thinking (researches and studies because it is focused on the way the changing of the electoral system influences the structure of political parliamentary elités. This study aims at revealing the connection between the electoral system and the structure of political élites, and it is based on two sociological researches that took place in the Romanian Parliament (Chamber of Deputies in two different chronological and political moments. The first chronological moment was in October 2008 and the second was in November 2009. The political moments are given by the presence of two different types of electoral systems. In the first research, the political élites analyzed belonged to a parliament elected by a proportional representation system (PR on closed lists, and in the second, the elections took place by „uninominal” system. It is shown that the change of electoral system from a period to another does determines the strategy of behavior of the political parliamentary élites and, implicitly, the functioning of parliamentary democracy through the political decisions that shape a certain behavior of élites.

Full Text Available La recomposición de las é lites políticas mexicanas durante la década de los ochenta se entrevera con la transfor mación del modelo de desarrollo: de uno predominante mente proteccionista y nacionalista a un modelo de corte neoliberal y aperturista. Dicha transformación he implicado cambios de fondo en las prácticas sociales de las é lites políticas. A partir de una base de datos que incluye a todos los funcionarios más importantes del perí odo 1988 - 2014, se investigan los mecanismos que estructuraron una red de poder transexenal y transnacional en México, así como los factores que favorecieron la organización de un campo de poder que se centra cada vez más en la frontera entre los espacios nacionales, regionales y globales. E ntre dichos mecanismos, encontramos : el contexto histórico internacional; la formación de equipos de trabajo con una visión del mundo predominantemente neoliberal; las trayectorias de los funcionarios; las reformas impulsadas ; el fluido tránsito entre posiciones públi cas y privadas; y las muy diversas relaciones que este grupo de funcionarios sostiene con organizaciones y otros actores transnacionales. Se concluye que las nuevas prácticas sociales de la s élites no sólo obstaculizan y socavan la formación de bienes públicos y de estructuras autónomas con la capacidad para planificar en función de un interés general, sino que promueven la depredación institucional.

In this paper we describe the use of CREAM and CEMonitor services for job submission and management within the gLite Grid middleware. Both CREAM and CEMonitor address one of the most fundamental operations of a Grid middleware, that is job submission and management. Specifically, CREAM is a job management service used for submitting, managing and monitoring computational jobs. CEMonitor is an event notification framework, which can be coupled with CREAM to provide the users with asynchronous job status change notifications. Both components have been integrated in the gLite Workload Management System by means of ICE (Interface to CREAM Environment). These software components have been released for production in the EGEE Grid infrastructure and, for what concerns the CEMonitor service, also in the OSG Grid. In this paper we report the current status of these services, the achieved results, and the issues that still have to be addressed.

On gLite WMS/LB monitoring and Management through WMSMonitor
International Nuclear Information System (INIS)
Cesini, D; Dongiovanni, D; Fattibene, E; Ferrari, T
2010-01-01
The Workload Management System is the gLite service supporting the distributed production and analysis activities of various HEP experiments. It is responsible of dispatching computing jobs to remote computing facilities by matching job requirements and the resource status information collected from the Grid information services. Given the distributed and heterogeneous nature of the Grid, the monitoring of the job lifecycle and of the aggregate workflow patterns generated by multiple user communities, and the reliability of the service are of great importance. In this paper we deal with the problem of WMS monitoring and management. We present the architecture and implementation of the WMSMonitor, a tool for WMS monitoring and management, which has been designed to meet the needs of various WMS user categories: administrators, developers, advanced Grid users and performance testers. The tool was successfully deployed to monitor the progress of WMS job submission activities during HEP computing challenges. We also describe how, for each WMS in a cluster, WMSMonitor produces status indexes and a load metric that can be used for automated notification of critical events via Nagios, or for ranking of service instances deployed in load balancing mode.

Mobile telephones have significant potential for use in psychological research, possessing unique characteristics-not least their ubiquity--that may make them useful tools for psychologists. We examined whether it is possible to measure reaction times (RTs) accurately using Adobe Flash Lite on mobile phones. We ran simple and choice RT experiments on two widely available mobile phones, a Nokia 6110 Navigator and a Sony Ericsson W810i, using a wireless application protocol (WAP) connection to access the Internet from the devices. RTs were compared within subjects with those obtained using a Linux-based millisecond-accurate measurement system. Results show that measured RTs were significantly longer on mobile devices, and that overall RTs and distribution of RTs varied across devices.

The Solar Alpha Rotary Joint (SARJ) is a mechanism of the International Space Station (ISS) that orients the solar power generating arrays toward the sun as the ISS orbits our planet. The orientation with the sun must be maintained to fully charge the ISS batteries and maintain all the other ISS electrical systems operating properly. In 2007, just a few months after full deployment, the starboard SARJ developed anomalies that warranted a full investigation including ISS Extravehicular Activity (EVA). The EVA uncovered unexpected debris that was due to degradation of a nitride layer on the SARJ bearing race. ISS personnel identified the failure root-cause and applied an aerospace grease to lubricate the area associated with the anomaly. The corrective action allowed the starboard SARJ to continue operating within the specified engineering parameters. The SARJ LITE (Lubrication Interval Test and Evaluation) program was initiated by NASA, Lockheed Martin, and Boeing to simulate the operation of the ISS SARJ for an extended time. The hardware was designed to test and evaluate the exact material components used aboard the ISS SARJ, but in a controlled area where engineers could continuously monitor the performance. After running the SARJ LITE test for an equivalent of 36+ years of continuous use, the test was opened to evaluate the metallography and lubrication. We have sampled the SARJ LITE rollers and plate to fully assess the grease used for lubrication. Chemical and thermal analysis of these samples has generated information that has allowed us to assess the location, migration, and current condition of the grease. The collective information will be key toward understanding and circumventing any performance deviations involving the ISS SARJ in the years to come.

On-orbit technology experiment facility definition
Russell, Richard A.; Buchan, Robert W.; Gates, Richard M.
1988-01-01
A study was conducted to identify on-orbit integrated facility needs to support in-space technology experiments on the Space Station and associated free flyers. In particular, the first task was to examine the proposed technology development missions (TDMX's) from the model mission set and other proposed experimental facilities, both individually and by theme, to determine how and if the experiments might be combined, what equipment might be shared, what equipment might be used as generic equipment for continued experimentation, and what experiments will conflict with the conduct of other experiments or Space Station operations. Then using these results, to determine on-orbit facility needs to optimize the implementation of technology payloads. Finally, to develop one or more scenarios, design concepts, and outfitting requirements for implementation of onboard technology experiments.

The Compact Muon Solenoid (CMS) is one of the general purpose experiments at the CERN Large Hadron Collider (LHC). CMS computing relies on different grid infrastructures to provide computational and storage resources. The major grid middleware stacks used for CMS computing are gLite, Open Science Grid (OSG) and ARC (Advanced Resource Connector). Helsinki Institute of Physics (HIP) hosts one of the Tier-2 centers for CMS computing. CMS Tier-2 centers operate software systems for data transfers (PhEDEx), Monte Carlo production (ProdAgent) and data analysis (CRAB). In order to provide the Tier-2 services for CMS, HIP uses tools and components from both ARC and gLite grid middleware stacks. Interoperation between grid systems is a challenging problem and HIP uses two different solutions to provide the needed services. The first solution is based on gLite-ARC grid level interoperability. This allows to use ARC resources in CMS without modifying the CMS application software. The second solution is based on developi...

Methods currently available for the measurement of oxygen concentrations (oximetry) in viable tissues differ widely from each other in their methodological basis and applicability. The goal of this study was to compare two novel methods, particulate-based electron paramagnetic resonance (EPR) and OxyLite oximetry, in an experimental tumor model. EPR oximetry uses implantable paramagnetic particulates, whereas OxyLite uses fluorescent probes affixed on a fiber-optic cable. C3H mice were transplanted with radiation-induced fibrosarcoma (RIF-1) tumors in their hind limbs. Lithium phthalocyanine (LiPc) microcrystals were used as EPR probes. The pO2 measurements were taken from random locations at a depth of ~3 mm within the tumor either immediately or 48 h after implantation of LiPc. Both methods revealed significant hypoxia in the tumor. However, there were striking differences between the EPR and OxyLite readings. The differences were attributed to the volume of tissue under examination and the effect of needle invasion at the site of measurement. This study recognizes the unique benefits of EPR oximetry in terms of robustness, repeatability and minimal invasiveness. PMID:17705635

2004-06-23
SLAC has been studying end-to-end WAN bandwidth availability and achievability for 2.5 years via IEPM-BW [1]. IEPM-BW performs network intensive tests every 90 minutes. Based on that experience we have also developed a light weight available bandwidth (ABwE [2]) measurement tool that can make a measurement within a second. We are now extending this to a WAN measurement and detection system (IEPM-LITE) aimed at more quickly detecting and troubleshooting network performance problems and also to be more friendly on lower performance paths. IEPM-LITE uses ping, forward traceroutes, and ABwE sensors to monitor, in close to real-time, Round Trip Times (RTT), changes in available bandwidth and routes to and from target hosts. This paper discusses the experiences, techniques and algorithms used to detect and report on significant traceroute and bandwidth changes. The ultimate aim is to develop a lightweight WAN network performance monitoring system that can detect, in near real time, significant changes and generate alerts.

SLAC has been studying end-to-end WAN bandwidth availability and achievability for 2.5 years via IEPM-BW [1]. IEPM-BW performs network intensive tests every 90 minutes. Based on that experience we have also developed a light weight available bandwidth (ABwE [2]) measurement tool that can make a measurement within a second. We are now extending this to a WAN measurement and detection system (IEPM-LITE) aimed at more quickly detecting and troubleshooting network performance problems and also to be more friendly on lower performance paths. IEPM-LITE uses ping, forward traceroutes, and ABwE sensors to monitor, in close to real-time, Round Trip Times (RTT), changes in available bandwidth and routes to and from target hosts. This paper discusses the experiences, techniques and algorithms used to detect and report on significant traceroute and bandwidth changes. The ultimate aim is to develop a lightweight WAN network performance monitoring system that can detect, in near real time, significant changes and generate alerts

The Compact Muon Solenoid (CMS) is one of the general purpose experiments at the CERN Large Hadron Collider (LHC). CMS computing relies on different grid infrastructures to provide computational and storage resources. The major grid middleware stacks used for CMS computing are gLite, Open Science Grid (OSG) and ARC (Advanced Resource Connector). Helsinki Institute of Physics (HIP) hosts one of the Tier-2 centers for CMS computing. CMS Tier-2 centers operate software systems for data transfers (PhEDEx), Monte Carlo production (ProdAgent) and data analysis (CRAB). In order to provide the Tier-2 services for CMS, HIP uses tools and components from both ARC and gLite grid middleware stacks. Interoperation between grid systems is a challenging problem and HIP uses two different solutions to provide the needed services. The first solution is based on gLite-ARC grid level interoperability. This allows to use ARC resources in CMS without modifying the CMS application software. The second solution is based on developing specific ARC plugins in CMS software.

How medical technologies shape the experience of illness.
Hofmann, Bjørn; Svenaeus, Fredrik
2018-02-03
In this article we explore how diagnostic and therapeutic technologies shape the lived experiences of illness for patients. By analysing a wide range of examples, we identify six ways that technology can (trans)form the experience of illness (and health). First, technology may create awareness of disease by revealing asymptomatic signs or markers (imaging techniques, blood tests). Second, the technology can reveal risk factors for developing diseases (e.g., high blood pressure or genetic tests that reveal risks of falling ill in the future). Third, the technology can affect and change an already present illness experience (e.g., the way blood sugar measurement affects the perceived symptoms of diabetes). Fourth, therapeutic technologies may redefine our experiences of a certain condition as diseased rather than unfortunate (e.g. assisted reproductive technologies or symptom based diagnoses in psychiatry). Fifth, technology influences illness experiences through altering social-cultural norms and values regarding various diagnoses. Sixth, technology influences and changes our experiences of being healthy in contrast and relation to being diseased and ill. This typology of how technology forms illness and related conditions calls for reflection regarding the phenomenology of technology and health. How are medical technologies and their outcomes perceived and understood by patients? The phenomenological way of approaching illness as a lived, bodily being-in-the-world is an important approach for better understanding and evaluating the effects that medical technologies may have on our health, not only in defining, diagnosing, or treating diseases, but also in making us feel more vulnerable and less healthy in different regards.

Full Text Available This article analyzes the "98" and its meanings, namely the fact that the Porto Rican élite acepted it as a path opened for developement of a modernizing project under US leadership. A re-organization of the country was expected as a consequence of the Empire's democratic liberalism. This was however resisted by the local economical, social and cultural conditions. Although some achievements must be recognized, it is necessary to analyze whom they benefited and what they were meant for.
Análisis de los significados del 98 a partir del estudio de la aceptación de la élite puertorriqueña, que en esa coyuntura vio la oportunidad de realizar un proyecto modernizador bajo la égida de Estados Unidos. El liberalismo democrático del imperio posibilitaría la puesta en marcha de una reorganización del país que, sin embargo, chocó con las condiciones particulares y estructuras económicas, sociales y culturales de Puerto Rico. Aceptando la consecución de algunos logros, cabe preguntarnos para qué se hicieron y quiénes se beneficiaron de ellos. -
Um satélite brasileiro para observação do diâmetro solar
Emilio, M.; Leister, N. V.; Benevides Soares, P.; Teixeira, R.; Kuhn, J.
2003-08-01
Propomos uma missão espacial para medir a forma e o diâmetro solar com o objetivo de ajudar a determinar o potencial gravitacional do Sol e a sua rotação com precisão, testar modelos teóricos de variação de energia e pela primeira vez medir os modos g de oscilação. As observações serão obtidas através do instrumento denominado APT (Astrometric and Photometric Telescope) descrito por Kuhn(1983). A sensibilidade do instrumento é de 0,2 mas em 27 dias para as observações do diâmetro solar feitas a cada minuto. Esta é uma missão de três anos de duração e pode complementar as medidas que serão feitas pelo satélite PICARD (a ser lançado em 2007). Outros parâmetros físicos podem ser obtidos com as mesmas imagens o que certamente interessará à comunidade de física solar. Um primeiro contato foi realizado com a agência espacial brasileira que pretende lançar um satélite científico a cada dois anos.

Estimación de pequeñas perturbaciones en satélites geocéntricos como un problema inverso
Zadunaisky, P. E.
El movimiento geocéntrico de un satélite artificial es simulado automáticamente por un sistema de ecuaciones diferenciales de segundo orden que incluyen dos funciones perturbadoras. La primera representa el segundo término del potencial gravitatorio de la Tierra y la segunda corresponde al frenado atmosférico. Asumiendo como conocidas, por hipótesis o por mediciones, la posición y velocidad del satélite en instantes sucesivos se estiman las perturbaciones a intervalos sucesivos por un método determinístico. Para ilustrar el método y comprobar la precisión de nuestros resultados hemos simulado dos ejemplos incluyendo valores conocidos de las perturbaciones que luego comparamos con los resultados de nuestro método. El método puede aplicarse por ejemplo para el intervalo de una revolución satelital lo cual permitiría el diseño inmediato de una maniobra correctiva de la órbita satelital.

This study examined the relations of preservice science teachers' attitudes towards technology use, technology ownership, technology competencies, and experiences to their self-efficacy beliefs about technological pedagogical content knowledge (TPACK). The present study also investigated interrelations among preservice teachers' attitudes towards technology use, technology ownership, technology competencies, and experiences. The participants of study were 665 elementary preservice science teachers (467 females, 198 males) from 7 colleges in Turkey. The proposed model based on educational technology literature was tested using structural equation modeling. The model testing results revealed that preservice teachers' technology competencies and experiences mediated the relation of technology ownership to their TPACK self efficacy beliefs. The direct relation of their possession of technology to their TPACK self efficacy beliefs was insignificant while the indirect relation through their technology competencies and experiences was significant. The results also indicated there were significant direct effects of preservice teachers' attitudes towards technology use, technology competencies, and experiences on their TPACK self efficacy beliefs.

O satélite Fraco-europeu COROT fará fotometria de altissima precisão (pretende-se atingir uma parte em um milhão), grande campo (3x3 graus) e por longos períodos, de duas regiões pré-determinadas do céu, com 10 graus de raio. Suas finalidades básicas serão estudos em sismologia estelar e a procura de exoplanetas. A comunidade astronômica brasileira participará dessa missão espacial, com direitos iguais aos dos parceiros europeus. Isso se deve a que o satélite utilizará a estação de recepção de dados de Natal (INPE), 5 a 6 brasileiros participarão das equipes de software e cientistas do país atuarão na fase de pré-lançamento. Apresentamos nesta comunicação sugestões para a preparação de propostas de observações com COROT, no âmbito dos Programas Adicionais, que contemplam outros projetos que não de sismologia ou exoplanetas. As últimas definições técnicas e decisões tomadas na 4th Corot Week de junho último serão igualmente apresentadas, em particular quanto às regiões de observação escolhidas e quanto aos procedimentos a seguir para se propor observações.

Full Text Available RESUMO Neste trabalho, objetivou-se avaliar a variabilidade genética da coleção de trabalho de acessos de araticum da Embrapa Cerrados e outros materiais próximos ao Distrito Federal, utilizando marcadores moleculares RAPD, microssatélites e análise de características morfológicas. Folhas de 18 acessos de araticum foram coletadas e utilizadas para a extração das amostras de DNA genômico, as quais foram amplificadas para obtenção de marcadores moleculares RAPD e microssatélites. Na análise morfológica, foram avaliadas 23 características dos acessos de araticum. As dissimilaridades genéticas entre os 18 genótipos de araticum evidenciaram a variabilidade genética dos acessos e as análises de agrupamento levaram à formação de três grupos de similaridade. Verificaram-se coeficientes de dissimilaridades genéticas baixos entre os materiais oriundos da Embrapa Cerrados e altos entre os outros materiais. Esses acessos são importantes fontes de variabilidade para o enriquecimento da atual coleção de trabalho da Embrapa Cerrados e para futuros estudos de caracterização morfológica e agronômica.

Technologies of democracy: experiments and demonstrations.
Laurent, Brice
2011-12-01
Technologies of democracy are instruments based on material apparatus, social practices and expert knowledge that organize the participation of various publics in the definition and treatment of public problems. Using three examples related to the engagement of publics in nanotechnology in France (a citizen conference, a series of public meetings, and an industrial design process), the paper argues that Science and Technology Studies provide useful tools and methods for the analysis of technologies of democracy. Operations of experiments and public demonstrations can be described, as well as controversies about technologies of democracy giving rise to counter-experiments and counter-demonstrations. The political value of the analysis of public engagement lies in the description of processes of stabilization of democratic orders and in the display of potential alternative political arrangements.

2015-01-01
Recently a new laser based approach for measuring area with potential for producing 2D estimates of the concentration spatial distribution has been developed through a cooperative agreement with the National Energy and Technology Laboratory of the Department of Energy, Exelis Inc. and AER Inc. The new approach is based on a pair of continuous wave intensity modulated laser absorption spectrometer transceivers, combined with a series of retro reflectors located around the perimeter of the area being monitored. The main goal of this cooperative agreement is monitoring, reporting and verification for ground carbon capture and storage projects. The system was recently tested at the Zero Emission Research and Technology site in Bozeman, MT, with underground leak rates ranging from 0.1 – 0.3 metric ton per day (T/d), as well as a 0.8 T/d surface release. Over 200 hours of data were collected over a rectangular grid 180m x 200m between August 18th and September 9th. In addition, multiple days of in situ data were acquired for the same site, using a Licor gas analyzer systems. Initial comparisons between the laser-based system and the in situ agree very well. The system is designed to operate remotely and transmit the data via a 3G/4G connection along with weather data for the site. An all web-based system ingests the data, populates a database, performs the inversion to ppm CO2 using the Line-by-Line Radiative Transfer Model (LBLRTM), and displays plots and statistics for the retrieved data. We will present an overview of the GreenLITE measurement system, outline the retrieval and reconstruction approach, and discuss results from extensive field testing.

En trabajos anteriores (Carpintero et al., Cel. Mech. Dynam. Astron. 85, 247, 2003), mostramos que las órbitas caóticas son muy importantes en los satélites galácticos. Sin embargo, los únicos modelos autoconsistentes de los que se disponía para ellos eran los de Heggie-Ramamani, cuya función de distribución depende sólo de la energía por lo que no mostraban diferencias entre las distribuciones de sus órbitas regulares y caóticas. Ahora, mediante una aproximación cuadrupolar, hemos logrado construir modelos autoconsistentes de satélites galácticos con distribuciones de velocidades anisotrópicas (lo que indica que sus funciones de distribución no dependen sólo de la energía) y hemos logrado revelar las diferencias entre las estructuras espaciales de las órbitas de distinta caoticidad.

Flight Test of a Technology Transparent Light Concentration Panel on SMEX/WIRE
Stern, Theodore G.; Lyons, John
2000-01-01
A flight experiment has demonstrated a modular solar concentrator that can be used as a direct substitute replacement for planar photovoltaic panels in spacecraft solar arrays. The Light Concentrating Panel (LCP) uses an orthogrid arrangement of composite mirror strips to form an array of rectangular mirror troughs that reflect light onto standard, high-efficiency solar cells at a concentration ratio of approximately 3:1. The panel area, mass, thickness, and pointing tolerance has been shown to be similar to a planar array using the same cells. Concentration reduces the panel's cell area by 2/3, which significantly reduces the cost of the panel. An opportunity for a flight experiment module arose on NASA's Small Explorer / Wide-Field Infrared Explorer (SMEX/WIRE) spacecraft, which uses modular solar panel modules integrated into a solar panel frame structure. The design and analysis that supported implementation of the LCP as a flight experiment module is described. Easy integration into the existing SMEX-LITE wing demonstrated the benefits of technology transparency. Flight data shows the stability of the LCP module after nearly one year in Low Earth Orbit.

Through theoretical studies of sociological crowd theory and pragmatist perspectives on experience combined with design exper- iments at sporting events this dissertation establishes an conceptual understanding of crowd experience. The outcome of this work is furthermore synthesized...... in a conceptual model of social experiences that presents crowd experiences as a distinct type of social experience. This is different from what previously have been explored within experi- ence-oriented design. This dissertation is composed of four research papers framed by an overview that summarizes...

The Advanced Communication Technology Satellite (ACTS) is a key to reaching NASA's goal of developing high-risk, advanced communications technology using multiple frequency bands to support the nation's future communication needs. Using the multiple, dynamic hopping spot beams, and advanced on board switching and processing systems, ACTS will open a new era in communications satellite technology. One of the key technologies to be validated as part of the ACTS program is the multibeam antenna with rapidly reconfigurable hopping and fixed spot beam to serve users equipped with small-aperature terminals within the coverage areas. The proposed antenna technology experiments are designed to evaluate in-orbit ACTS multibeam antenna performance (radiation pattern, gain, cross pol levels, etc.).

El presente estudio se llevó a cabo en el Valle del Mezquital, en el estado de Hidalgo, el cual tiene problemas de contaminación por las aguas residuales que se utilizan para regar las tierras agrícolas. Se valoraron y clasificaron las tierras según su nivel de concentración de nitratos a través de imágenes de satélite Landsat-TM, el programa IDRISI y datos de campo. Los resultados indicaron que a través de las imágenes de satélite es posible indicar los niveles de concentración de nitratos en capas de suelo de 60-90 cm de profundidad, donde las altas concentraciones de nitratos están directamente asociadas a la lixiviación de estos y causan problemas de contaminación. Cuando se usa el cultivo de alfalfa como indicador, la imagen de satélite muestra un 91.88 % de certeza de obtener las concentraciones de nitratos, y cuando se usa el cultivo de maíz, la imagen sólo muestra un 63.33 % de certeza.

The recently developed Canadian Health Care Evaluation Project (CANHELP) questionnaire, which can be used to assess both patient and family satisfaction with end-of-life care, takes 40-60 minutes to complete. The length of the interview may limit its uptake and clinical utility; a shorter version would make its use more feasible. The purpose of this study was to develop and validate a shorter version of the CANHELP questionnaire. Data were collected using a cross-sectional survey of patients with advanced medical diseases and their family members. Participants completed the long version of CANHELP, a global rating of satisfaction with care (GRS), the FAMCARE scale (family members only), and a quality-of-life (QOL) questionnaire. We reduced the items on the long version based on their relationship to the GRS, the frequency of missing data, the distribution of responses, the redundancy of the items, and focus groups with frontline users. With the remaining items, we assessed internal consistency using Cronbach's alpha, and evaluated construct validity by describing the correlation of the new CANHELP Lite with the full version of CANHELP, GRS, FAMCARE, and the QOL questionnaire scores. A total of 363 patients and 193 family members participated in this study. The patient version was reduced from 37 items to 20 items and the caregiver version was reduced from 38 items to 21 items. Cronbach's alphas ranged from 0.68 to 0.93 for all domains of both the patient and caregiver questionnaires. We observed a high degree of correlation between CANHELP Lite domains and overall scores and the same domains and overall scores for the full version of CANHELP. In addition, we observed moderate to strong correlation between the CANHELP Lite overall satisfaction scores and the GRS questions. There was moderate correlation between the overall family member CANHELP Lite score and overall FAMCARE score (r = 0.45) and this was similar to the correlation between the full version of

Full Text Available RESUMEN: El caso de Rafael Gasset, propietario y director de "El Imparcial", sirve como modelo ilustrativo del ascenso político y social protagonizado por las élites salidas del periodismo desde fines del siglo XIX. El protagonismo político asumido por Gasset en la crítica coyuntura del 98 sería inexplicable sin tener en cuenta el crédito que le confería su periódico, el diario de más influencia en la España de la Restauración. Todo partido y todo líder político necesitaban en aquellos momentos ejercer algún tipo de control e influencia sobre un gran periódico. Sin él, la jefatura y los partidos no valían nada. Por ello, el periodismo era ya, a fines del siglo XIX, uno de los medios más representativos de ascenso en la política profesional y en el liderazgo social. Las campañas periodísticas de "El imparcial" (Madrid, 1867-1933 fueron, durante décadas, decisivas en la creación de estados de opinión. Estas campañas serían el medio utilizado por Gasset para influir sobre los medios oficiales y para integrarse, de ese modo, en la élite gobernante del régimen de la Restauraciuón. Esta integración se produjo al ser nombrado ministro de Agricultura por Francisco Silvela en abril de 1900. La estrecha vinculación existente desde entonces entre los intereses políticos y periodísticos del nuevo ministro, sin embargo, habría de pagarla muy cara su órgano de información, en términos de pérdida de credibilidad y prestigio entre el público lector independiente. Palabras Clave: Restauración Española, Élites políticas, Periodismo, Opinión pública, Política de masas.

Modelo analítico del efecto de PRS sobre satélites GPS
Meza, A.; Brunini, C.; Usandivaras, J. C.
El sistema GPS (Global Position System) es, hoy en día, la herramienta de navegación y posicionamiento más potente y lo será sin duda en la próxima década. Gran parte de su valiosa utilidad se debe a la alta precisión que permite lograr y ésta, a su vez, depende, entre otras causas, de la precisión con que se conocen las órbitas de los satélites. La presión de radiación solar (PRS) fija el límite de la precisión con que pueden calcularse en la actualidad las efemérides satelitarias. El objetivo de este trabajo es proponer una mejor resolución de este fenómeno. El modelo analítico aquí presentado, se basa en el análisis del comportamiento de los residuos de un ajuste por mínimos cuadrados en el que se utiliza el modelo de PRS propuesto por Beutler. El mismo consiste en un modelo determinista del fenómeno con dos parámetros libres. Los resultados obtenidos ponen de manifiesto que, aún después de aplicar dichos parámetros, prevalecen en los residuos efectos semidiurnos en las componentes radial,tangencial y normal. Estos resultados obtenidos se comparan con los de un trabajo desarrollado por el Instituto de Berne (Beutler et al., 1994), en el que se utilizaron como pseudo-observaciones las órbitas precisas del IGS (CODE). El intervalo de integración escogido por este centro fueron las semanas 680 y 681. En resumen se tienen arcos de 14 días para todos los satélites, donde las efemérides precisas de los mismos para los 14 días fueron utilizados como pseudo-observaciones. El modelo de fuerza que empleó dicho centro fue básicamente el tradicional en lo que respecta al modelo de las fuerzas gravitacionales, y para la PRS utilizo el modelo standard de Beutler. Los parámetros de este modelo junto con las 6 condiciones iniciales (posición y velocidad) fueron ajustados por el método general de mínimos cuadrados. Los residuos en la componente radial, tangencial y normal, para los satélites con un buen comportamiento, presentan una

A training system with quantitative evaluation of performance for training perfusionists is valuable for preparation for rare but critical situations. A simulator system, ECCSIM-Lite, for extracorporeal circulation (ECC) training of perfusionists was developed. This system consists of a computer system containing a simulation program of the hemodynamic conditions and the training scenario with instructions, a flow sensor unit, a reservoir with a built-in water level sensor, and an ECC circuit with a soft bag representing the human body. This system is relatively simple, easy to handle, compact, and reasonably inexpensive. Quantitative information is recorded, including the changes in arterial flow by the manipulation of a knob, the changes in venous drainage by handling a clamp, and the change in reservoir level; the time courses of the above parameters are presented graphically. To increase the realism of the training, a numerical-hydraulic circulatory model was applied. Following the instruction and explanation of the scenario in the form of audio and video captions, it is possible for a trainee to undertake self-study without an instructor or a computer operator. To validate the system, a training session was given to three beginners using a simple training scenario; it was possible to record the performance of the perfusion sessions quantitatively. In conclusion, the ECCSIM-Lite system is expected to be useful for perfusion training, since quantitative information about the trainee's performance is recorded and it is possible to use the data for assessment and comparison.

Canadian Experience in Nuclear Power Technology Transfer
International Nuclear Information System (INIS)
Boulton, J.
1987-01-01
Technology transfer has and will continue to play a major role in the development of nuclear power programs. From the early beginnings of the development of the peaceful uses of nuclear power by just a few nations in the mid-1940s there has been a considerable transfer of technology and today 34 countries have nuclear programs in various stages of development. Indeed, some of the major nuclear vendors achieves their present position through a process of technology transfer and subsequent development. Canada, one of the early leaders in the development of nuclear power, has experience with a wide range of programs bout within its own borders and with other countries. This paper briefly describes this experience and the lessons learned from Canada's involvement in the transfer of nuclear power technology. Nuclear technology is complex and diverse and yet it can be assimilated by a nation given a fire commitment of both suppliers and recipients of technology to achieve success. Canada has reaped large benefits from its nuclear program and we believe this has been instrumentally linked to the sharing of goals and opportunity for participation over extended periods of time by many interests within the Canadian infrastructure. While Canada has accumulated considerable expertise in nuclear technology transfer, we believe there is still much for US to learn. Achieving proficiency in any of the many kinds of nuclear related technologies will place a heavy burden on the financial and human resources of a nation. Care must be taken to plan carefully the total criteria which will assure national benefits in industrial and economic development. Above all, effective transfer of nuclear technology requires a long term commitment by both parties

Technology adoption subsidies. An experiment with managers
International Nuclear Information System (INIS)
Aalbers, Rob; Van der Heijden, Eline; Potters, Jan; Van Soest, Daan; Vollebergh, Herman
2009-01-01
We evaluate the impact of technology adoption subsidies on investment behavior in an individual choice experiment. In a laboratory setting professional managers are confronted with an intertemporal decision problem in which they have to decide whether or not to search for, and possibly adopt, a new technology. Technologies differ in the per-period benefits they yield, and their purchase price increases with the per-period benefits provided. We introduce a subsidy on the more expensive technologies (that also yield larger per-period benefits), and find that the subsidy scheme induces agents to search for and adopt these more expensive technologies even though the subsidy itself is too small to render these technologies profitable. We speculate that the result is driven by the positive connotation (affect) that the concept 'subsidy' invokes. (author)

Experience Scaling Up Manufacturing of Emerging Photovoltaic Technologies
Energy Technology Data Exchange (ETDEWEB)
Braun, G. W.; Skinner, D. E.
2007-01-01
This report examines two important generic photovoltaic technologies at particularly revealing stages of development, i.e., the stages between R&D and stable commercial production and profitable sales. Based on two historical cases, it attempts to shed light on the difference between: (1) costs and schedules validated by actual manufacturing and market experience, and (2) estimated costs and schedules that rely on technology forecasts and engineering estimates. The amorphous Silicon case also identifies some of the costs that are incurred in meeting specific market requirements, while the Cadmium Telluride case identifies many of the operational challenges involved in transferring R&D results to production. The transition between R&D and commercial success takes a great deal of time and money for emerging energy conversion technologies in general. The experience reported here can be instructive to those managing comparable efforts, and to their investors. It can also be instructive to R&D managers responsible for positioning such new technologies for commercial success.

Pakistan's experience in transfer of nuclear technology
International Nuclear Information System (INIS)
Ahmad Khan, Nunir
1977-01-01
Of all technologies, nuclear technology is perhaps the most interdisciplinary in character as it encompasses such varied fields as nuclear physics, reactor physics, mechanical, electrical electronics controls, metallurgical and even civil and geological engineering. When we speak of transfer of acquisition of nuclear technology we imply cumulative know-how in many fields, most of which are not nuclear per se but are essential for building the necessry infrastructure and back-up facilities for developing and implementing any nuclear energy program. In Pakistan, efforts on utilization of nuclear energy for peaceful applications were initiated about twenty years ago. During these years stepwise development of nuclear technology has taken place. The experience gained by Pakistan so far in transfer of nuclear technology is discussed. Suggestions have been made for continuing the transfer of this most essential technology from the advanced to the developing countries while making sure that necessary safeguard requirements are fullfilled

Controle orbital de satélites artificiais com propulsão e uso de gravidade lunar
Torres, K. S.; de Almeida Prado, A. F. B.
2003-08-01
A redução do custo de combustível de uma manobra é atualmente a grande prioridade de todos os programas espaciais existentes no mundo. As manobras assistidas pela gravidade são uma ótima forma de se contornar o problema pois proporcionam economias com vasto impacto no custo final da missão. Neste trabalho é feito um estudo particular do controle orbital de um satélite artificial da Terra usando a gravidade da Lua. O objetivo é estudar uma técnica econômica para uma mudança de plano de um satélite que está em órbita em volta da Terra. A idéia principal desta abordagem é enviar primeiramente o veículo espacial em direção à Lua usando uma manobra mono-impulsiva para que assim o campo gravitacional da Lua possa fazer a mudança de plano desejada (sem custo de combustível) e só então retornar o veículo aos valores iniciais de semi-eixo e excentricidade usando uma manobra bi-impulsiva tipo Hohmann. Para tanto, é assumido que a espaçonave inicia em uma órbita circular coplanar à órbita da lua em torno da Terra e a meta é colocá-la em uma órbita similar que difere da órbita inicial somente pela inclinação. São usadas equações analíticas baseadas na abordagem Patched Conics para se calcular a variação na velocidade, momento angular, energia e inclinação do veículo espacial que realiza esta manobra. Várias simulações são feitas para se avaliar as economias de combustível envolvidas.

This paper presents first on orbit measured data from the Forward Technology Solar Cell Experiment (FTSCE). FTSCE is a space experiment housed within the 5th Materials on the International Space Station Experiment (MISSE-5). MISSE-5 was launched aboard the Shuttle return to flight mission (STS-114) on July 26, 2005 and deployed on the exterior of the International Space Station (ISS). The experiment will remain in orbit for nominally one year, after which it will be returned to Earth for post-flight testing and analysis. While on orbit, the experiment is designed to measure a 36 point current vs. voltage (IV) curve on each of the experimental solar cells, and the data is continuously telemetered to Earth. The experiment also measures the solar cell temperature and the orientation of the solar cells to the sun. A range of solar cell technologies are included in the experiment including state-of-the-art triple junction InGaP/GaAs/Ge solar cells from several vendors, thin film amorphous Si and CuIn(Ga)Se2 cells, and next-generation technologies like single-junction GaAs cells grown on Si wafers and metamorphic InGaP/InGaAs/Ge triple-junction cells. In addition to FTSCE, MISSE-5 also contains a Thin-Film Materials experiment. This is a passive experiment that will provide data on the effect of the space environment on more than 200 different materials. FTSCE was initially conceived in response to various on-orbit and ground test anomalies associated with space power systems. The Department of Defense (DoD) required a method of rapidly obtaining on orbit validation data for new space solar cell technologies, and NRL was tasked to devise an experiment to meet this requirement. Rapid access to space was provided by the MISSE Program which is a NASA Langley Research Center program. MISSE-5 is a completely self-contained experiment system with its own power generation and storage system and communications system. The communications system, referred to as PCSat, transmits

Full Text Available En la sociedad del riesgo, la aceleración y multiplicación de las crisis políticas y la incertidumbre producida por efectos de la modernización democrática genera vacíos políticos, que son ocupados por actores de la sociedad civil al asumir responsabilidades de gobierno. Pero se pueden rastrear rasgos autoritarios, reflejos de las continuidades de la cultura política latinoamericana, donde las élites reaparecen con un papel de liderazgo. Así el autoritarismo con rostro democrático se originaría, no tanto en la supuesta separación teórica entre Estado y sociedad civil, sino más bien en su compenetración, en su batalla por definir la gubernamentalidad, expresada a través de la sobre-representación de las élites y la paulatina desaparición de la auto-representación de los sectores populares.

Experiences of technology integration in home care nursing.
Johnson, K A; Valdez, R S; Casper, G R; Kossman, S P; Carayon, P; Or, C K L; Burke, L J; Brennan, P F
2008-11-06
The infusion of health care technologies into the home leads to substantial changes in the nature of work for home care nurses and their patients. Nurses and nursing practice must change to capitalize on these innovations. As part of a randomized field experiment evaluating web-based support for home care of patients with chronic heart disease, we engaged nine nurses in a dialogue about their experience integrating this modification of care delivery into their practice. They shared their perceptions of the work they needed to do and their perceptions and expectations for patients and themselves in using technologies to promote and manage self-care. We document three overarching themes that identify preexisting factors that influenced integration or represent the consequences of technology integration into home care: doing tasks differently, making accommodations in the home for devices and computers, and being mindful of existing expectations and skills of both nurses and patients.

The plasma focus - numerical experiments leading technology
International Nuclear Information System (INIS)
Saw, S.H.; Lee, S.
2013-01-01
Numerical experiments on the plasma focus are now used routinely to assist design and provide reference points for diagnostics. More importantly guidance has been given regarding the implementation of technology for new generations of plasma focus devices. For example intensive series of experiments have shown that it is of no use to reduce static bank inductance L0 below certain values because of the consistent loading effects of the plasma focus dynamics on the capacitor bank. Thus whilst it was thought that the PF1000 could receive major benefits by reducing its bank inductance L 0 , numerical experiments have shown to the contrary that its present L 0 of 30 nH is already optimum and that reducing L 0 would be a very expensive fruitless exercise. This knowledge gained from numerical experiments now acts as a general valuable guideline to all high performance (ie low inductance) plasma focus devices not to unnecessarily attempt to further lower the static inductance L 0 . The numerical experiments also show that the deterioration of the yield scaling law (e.g. the fusion neutron yield scaling with storage energy) is inevitable again due to the consistent loading effect of the plasma focus, which becomes more and more dominant as capacitor bank impedance reduces with increasing capacitance C 0 as storage energy is increased. This line of thinking has led to the suggestion of using higher voltages (as an alternative to increasing C 0 ) and to seeding of Deuterium with noble gases in order to enhance compression through thermodynamic mechanisms and through radiation cooling effects of strong line radiation. Circuit manipulation e.g. to enhance focus pinch compression by current-stepping is also being numerically experimented upon. Ultimately however systems have to be built, guided by numerical experiments, so that the predicted technology may be proven and realized. (author)

Full Text Available The Internet and computer technology have altered the education landscape. Online courses are offered throughout the world. Learning about the experiences of faculty members is important to guide practitioners and administrators. Using qualitative research methodology, this study investigated the experiences of faculty members teaching online courses. A convenience sampling was used to select the instructional technology faculty members to investigate their experiences in online courses. Semi-structured interviews with faculty members teaching online courses were used as the primary source to collect data about the experiences of faculty members in online courses. Results of the study showed that faculty members' interest in using technology and the amount of time available to them for online course design affected the quality of online courses. The findings of this study also indicated that design quality of online courses is affected by the interest of faculty members to use the technology and the time that they can devote to planning, designing, and developing online courses. The poor design of existing online courses, high learning expectations of ndividuals from these courses, and the future of online courses are the concerns of faculty members. Higher education institutions should support workshops and trainings to increase the skills and interests of non-instructional design faculty members to design and develop online courses.

2012-01-01
To manage data in the grid, with its jungle of protocols and enormous amount of data in different storage solutions, it is important to have a strong, versatile and reliable data management library. While there are several data management tools and libraries available, they all have different strengths and weaknesses, and it can be hard to decide which tool to use for which purpose. EMI is a collaboration between the European middleware providers aiming to take the best out of each middleware to create one consolidated, all-purpose grid middleware. When EMI started there were two main tools for managing data - gLite had lcg util and the GFAL library, ARC had the ARC data tools and libarcdata2. While different in design and purpose, they both have the same goal; to manage data in the grid. The design of the new EMI datalib was ready by the end of 2011, and a first prototype is now implemented and going through a thorough testing phase. This presentation will give the latest results of the consolidated library together with an overview of the design, test plan and roadmap of EMI datalib.

Modern Grid middleware is built around components providing basic functionality, such as data storage, authentication, security, job management, resource monitoring and reservation. In this paper we describe the Computing Resource Execution and Management (CREAM) service. CREAM provides a Web service-based job execution and management capability for Grid systems; in particular, it is being used within the gLite middleware. CREAM exposes a Web service interface allowing conforming clients to submit and manage computational jobs to a Local Resource Management System. We developed a special component, called ICE (Interface to CREAM Environment) to integrate CREAM in gLite. ICE transfers job submissions and cancellations from the Workload Management System, allowing users to manage CREAM jobs from the gLite User Interface. This paper describes some recent studies aimed at assessing the performance and reliability of CREAM and ICE; those tests have been performed as part of the acceptance tests for integration of CREAM and ICE in gLite. We also discuss recent work towards enhancing CREAM with a BES and JSDL compliant interface.

Beckurts, K.H.
1977-01-01
Nuclear energy development in the Federal Republic of Germany was initiated in 1955. In spite of this late start, the country now has a broad potential in all branches of peaceful nuclear technology. Turkey nuclear power plants are erected by German industry, and the country has the basic technology at its disposal for all stages of the nuclear fuel cycle. In the areas of uranium enrichment and reprocessing, multilateral joint ventures with European countries have been formed. The country also has an active development program for advanced reactors. In general areas of technology transfer and development aid, in the nuclear field, there are interrelated activities of both government and industry. The government has concluded bilateral agreements with a number of countires e.g. Argentina, Brazil, India, Iran and Pakistan, covering the general field of nuclear science; in the framework of these agreements, which are being carried out mainly by the nuclear research centers at Juelich and Karlsruhe, active cooperation in research, development, education, and training are being pursued. The nonproliferation of nuclear weapons is a major objective of the Federal government which strongly affects its policies for international nuclear trade. The paper describes the nuclear technology potential available in the Federal Republic of Germany and reviews experience gathered in cooperation with developing countries. Future policies for nuclear technology transfer are discussed with special reference to the role of national R and D laboratories

European pharmacy students' experience with virtual patient technology.
Cavaco, Afonso Miguel; Madeira, Filipe
2012-08-10
To describe how virtual patients are being used to simulate real-life clinical scenarios in undergraduate pharmacy education in Europe. One hundred ninety-four participants at the 2011 Congress of the European Pharmaceutical Students Association (EPSA) completed an exploratory cross-sectional survey instrument. Of the 46 universities and 23 countries represented at the EPSA Congress, only 12 students from 6 universities in 6 different countries reported having experience with virtual patient technology. The students were satisfied with the virtual patient technology and considered it more useful as a teaching and learning tool than an assessment tool. Respondents who had not used virtual patient technology expressed support regarding its potential benefits in pharmacy education. French and Dutch students were significantly less interested in virtual patient technology than were their counterparts from other European countries. The limited use of virtual patients in pharmacy education in Europe suggests the need for initiatives to increase the use of virtual patient technology and the benefits of computer-assisted learning in pharmacy education.

Technologically-mediated communication: student expectations and experiences in a FOMO society

Angela T. Ragusa
2017-11-01
Full Text Available Abstract While technology enables a wider section of society to access higher education, accessing, as a process, fundamentally differs from acquiring the individual and systemic skills required for online learning. This study presents primary data about perceptions of, and experiences with, online learning in an Australian university from a survey of 289 distance education (DE students. Epistemologically, it prioritises giving agency and voice to an increasingly disempowered collective, online learners, who often are institutionally pursued for economic advantage, rather than pedagogical interest in serving students’ unique, individual needs/preferences. Participants’ comparison of face-to-face and online learning experiences allowed for benefits and disadvantages of online learning to emerge from lived-experiences. While a key benefit of online learning was its perceived ‘flexibility’, findings revealed difference between students’ conceptualisation of flexibility and institutional realities. Although DE students longed for non-technologically-medicated communication with peers and lecturers, the process of learning how to become a DE student failed to address students’ needs/concerns beyond technical skill acquisition and subject content mastery. Students’ ‘fear they were missing out’ (FOMO on ‘better’ internal classroom and learning experiences was a key limitation 85% perceived about DE. Whereas traditional classroom experiences generally were recalled favourably, online learning was described by its shortcomings. Findings demonstrate need for deeper investigation of how/why educational technologies are implemented. Conclusions suggest critical research investigating whether embedded technologies meet student and/or institutional needs and aspirations in globally competitive learning environments may assuage DE’s stigma, realign expectations and improve teaching/learning experiences.

1989-12-31
In August 1989 the Office of the Chief of Naval Research and the American Defense Preparedness Association conducted the first Navy Domestic Technology Transfair. The objective of the Transfair was to expose the US Navy`s years of solid experience across a broad span of technology to organizations outside of the Navy. It was an opportunity for private industry to capitalize on the Navy developed technology and this opening for industry was the primary focus of the Transfair. The event provided a unique forum to meet leading Navy scientific and engineering innovators face-to-face. Information was available concerning licensing of naval technology that was for sale to the private sector. Further, discussions covered opportunities for new cooperative research and development agreements with Navy laboratories and R&D activities. These agreements were authorized under the Federal Technology Transfer Act of 1986. The Transfair program was conducted in such a manner as to allow each Navy inventor, either scientist or engineer, to present a system, piece of hardware, or licensable concept in a formal paper presentation. Then, the Navy inventors were available in two, two-hour periods in which individual discussions were conducted, with attendees pursuing specific venues of cooperative agreements as desired. This report provides specifics concerning the technologies that were made available for transfer to the private sector during the Transfair. The Transfair concept sought to add special emphasis to the opening that the 1988 Technology Transfer Act brought to the marketplace. The experience was a step in the education of the possibilities for cooperation between the government and the private sector to share technology. Of additional significance is the economic enhancement for business expansion with the application of the technology to markets beyond defense.

This paper examines how young peoples' lived experiences with personal technologies can be used to teach engineering ethics in a way which facilitates greater engagement with the subject. Engineering ethics can be challenging to teach: as a form of practical ethics, it is framed around future workplace experience in a professional setting which students are assumed to have no prior experience of. Yet the current generations of engineering students, who have been described as 'digital natives', do however have immersive personal experience with digital technologies; and experiential learning theory describes how students learn ethics more successfully when they can draw on personal experience which give context and meaning to abstract theories. This paper reviews current teaching practices in engineering ethics; and examines young people's engagement with technologies including cell phones, social networking sites, digital music and computer games to identify social and ethical elements of these practices which have relevance for the engineering ethics curricula. From this analysis three case studies are developed to illustrate how facets of the use of these technologies can be drawn on to teach topics including group work and communication; risk and safety; and engineering as social experimentation. Means for bridging personal experience and professional ethics when teaching these cases are discussed. The paper contributes to research and curriculum development in engineering ethics education, and to wider education research about methods of teaching 'the net generation'.

The presence of oxygen-deficient tumor cells is a critical issue in cancer therapy. To identify tumor hypoxia, tissue partial oxygen pressure (pO2) can be measured directly. The OxyLite system allows determination of pO2 in tumors and permits continuous measurements of pO2 at a fixed point. In this study, this system was used to continuously measure pO2 in R3327-AT tumors in animals anesthetized with isoflurane. In addition, continuous pO2 measurement was performed in the muscle in non-tumor-bearing animals. In animals breathing isoflurane balanced by air, tumor pO2 at fixed positions decreased rapidly within 1-2 min of probe positioning but remained stable thereafter. In animals breathing isoflurane balanced by pure oxygen, tumor pO2 was higher and remained high. We also measured pO2 values at multiple positions in R3327-AT tumors of various sizes, with anesthetized animals breathing either air or pure oxygen. Our data showed that the frequency of pO2 measurements below 2.5 or 5.0 mmHg was significantly higher in animals breathing air than in animals breathing pure oxygen. Measurements in different-sized tumors showed that the mean pO2 value decreased as tumor volume increased, with the largest change occurring between tumor volumes of 100 and 200 mm3. Our data demonstrate that the OxyLite system, when used with isoflurane anesthesia, is a valuable tool in the study of tumor hypoxia.

An economic perspective on experience curves and dynamic economies in renewable energy technologies
International Nuclear Information System (INIS)
Papineau, Maya
2006-01-01
This paper analyzes dynamic economies in renewable energy technologies. The paper has two contributions. The first is to test the robustness of experience in solar photovoltaic, solar thermal and wind energy to the addition of an explicit time trend, which has been done in experience studies for other industries, but not for renewable energy technologies. Estimation is carried out on the assumption that cumulative capacity, industry production, average firm production, and electricity generation affect experience and thus the fall in price. The second contribution is to test the impact of R and D on price reduction. In general cumulative experience is found to be highly statistically significant when estimated alone, and highly statistically insignificant when time is added to the model. The effect of R and D is small and statistically significant in solar photovoltaic technology and statistically insignificant in solar thermal and wind technologies

Using assistive technology for schoolwork: the experience of children with physical disabilities.
Murchland, Sonya; Parkyn, Helen
2010-01-01
This study explored the experience of children with physical disabilities using assistive technology for participation with schoolwork to gain a greater understanding of their perspectives and subjective experiences. A qualitative study involving thematic analysis of in-depth interviews of the child with a parent or significant adult. Purposeful sampling from a larger study recruited five children aged between 10 and 14 years, with differing physical disabilities who attended mainstream schools. All children used computer-based assistive technology. All of the children recognised that assistive technology enabled them to participate and reduced the impact of their physical disability, allowing independent participation, and facilitated higher learning outcomes. Issues related to ease of use, social implications and assistive technology systems are discussed.

Full Text Available Today’s youngsters interact with digital technologies to a great extent which leads scholars to question the influence of this exposure on human cognitive structure. Through resorting to digital nativity assumptions, it is presumed that cognitive architecture of the youth may change in accordance with digital technology use. In this regard, the current study investigated the relationship between digital technology experience, daily media exposure and working memory capacity of so-called digital native participants. A total of 572 undergraduate students responded to self-report measures, which addressed years of experience for 7 different digital devices and the daily time spent for 14 different digital activities. Participants’ working memory capacity was measured through the Computation Span and the Dot Matrix Test. While the former was used to measure the phonological loop capacity, the latter was used to address the visuo-spatial sketchpad capacity. Correlational analyses revealed that neither the phonological loop capacity nor the visuo-spatial sketchpad capacity was related to digital technology experience and daily media exposure. Thus, the transformative contribution of digital technology experience to human cognitive architecture could not be observed through the current measures

Performance of active vibration control technology: the ACTEX flight experiments
Nye, T. W.; Manning, R. A.; Qassim, K.
1999-12-01
This paper discusses the development and results of two intelligent structures space-flight experiments, each of which could affect architecture designs of future spacecraft. The first, the advanced controls technology experiment I (ACTEX I), is a variable stiffness tripod structure riding as a secondary payload on a classified spacecraft. It has been operating well past its expected life since becoming operational in 1996. Over 60 on-orbit experiments have been run on the ACTEX I flight experiment. These experiments form the basis for in-space controller design problems and for concluding lifetime/reliability data on the active control components. Transfer functions taken during the life of ACTEX I have shown consistent predictability and stability in structural behavior, including consistency with those measurements taken on the ground prior to a three year storage period and the launch event. ACTEX I can change its modal characteristics by employing its dynamic change mechanism that varies preloads in portions of its structure. Active control experiments have demonstrated maximum vibration reductions of 29 dB and 16 dB in the first two variable modes of the system, while operating over a remarkable on-orbit temperature range of -80 °C to 129 °C. The second experiment, ACTEX II, was successfully designed, ground-tested, and integrated on an experimental Department of Defense satellite prior to its loss during a launch vehicle failure in 1995. ACTEX II also had variable modal behavior by virtue of a two-axis gimbal and added challenges of structural flexibility by being a large deployable appendage. Although the loss of ACTEX II did not provide space environment experience, ground testing resulted in space qualifying the hardware and demonstrated 21 dB, 14 dB, and 8 dB reductions in amplitude of the first three primary structural modes. ACTEX II could use either active and/or passive techniques to affect vibration suppression. Both experiments trailblazed

New technologies in robotic surgery: the Korean experience.
Tuliao, Patrick H; Kim, Sang W; Rha, Koon H
2014-01-01
The development of the robotic systems has made surgery an increasingly technology-driven field. Since the introduction of the first robotic platform in 2005, surgical practice in South Korea has also been caught up in the global robotic revolution. Consequently, a market focused on improving the robotic systems was created and Korea has emerged as one of its frontrunners. This article reviews the Korean experience in developing various robotic technologies and then Korea's most recent contributions to the development of new technologies in robotic surgery. The goal of new technologies in the field of robotic surgery has been to improve on the current platforms by eliminating their disadvantages. The pressing goal is to develop a platform that is less bulky, more ergonomic, and capable of providing force feedback to the surgeon. In Korea, the Lapabot and two new robotic systems for single-port laparoscopic surgery are the most recent advances that have been reported. Robotic surgery is rapidly evolving and Korea has stayed in the forefront of its development. These new advancements in technology will eventually produce better robotic platforms that will greatly improve the manner in which surgical care is delivered.

Therefore, various effort modernize society involve program of transfer technology in main agenda. Purpose of this study is to choose a process of technology transfer and according to be able to reach for technological ability of nuclear power self-reliance. This research is conducted by study of existing literature, namely learn from experience of Korea which have succeeded to develop nuclear energy technology with self-reliance. While this research scope is to describe the process of technology transfer and according to be able to reach for technological ability of nuclear energy self-reliance. This study conclude that program of technology transfer have to start since nuclear power development pre-project period, project construction of NPP period and also in operation period. To reach for technological ability of self-reliance require to be done by long-term program and require to be build by several units which last for a transfer of technology. Government Commitment to have important role also have to be strong to push the happening of technology transfer. Institutions in concerned should have to be clear and hold responsible according to its interest. National industries as executor of technology transfer require to be given by larger ones opportunity in course of transfer this technology. (author)

Full Text Available Information and communication technology (ICT is a prime modality of ordering in the contemporary world. However, order creates and needs its own disorder, and ICT has a long record of failing to deliver on its promises and creating the experience of disorder. This paper looks at the myths of ordering around ICT and then looks at people's experiences of ICT disorder. In particular it looks at three factors: the informal networks that develop because of problems with ICT and with ICT help; the failure of management and communication in hierarchy and finally the failure of requirements engineering to live up to its promise. This focus on disorder may suggest a new way of approaching the so-called ‘Information Society’.

The Starshine 3 satellite will carry several power technology demonstrations. Since Starshine 3 is primarily a passive experiment and does not need electrical power to successfully complete its mission, the requirement for a highly reliable power system is greatly reduced. This creates an excellent opportunity to test new power technologies. Several government and commercial interests have teamed up to provide Starshine 3 with a small power system using state-of-the-art components. Starshine 3 will also fly novel integrated microelectronic power supplies (IWS) for evaluation.

Utilizing HPC Network Technologies in High Energy Physics Experiments
AUTHOR|(CDS)2088631; The ATLAS collaboration
2017-01-01
Because of their performance characteristics high-performance fabrics like Infiniband or OmniPath are interesting technologies for many local area network applications, including data acquisition systems for high-energy physics experiments like the ATLAS experiment at CERN. This paper analyzes existing APIs for high-performance fabrics and evaluates their suitability for data acquisition systems in terms of performance and domain applicability. The study finds that existing software APIs for high-performance interconnects are focused on applications in high-performance computing with specific workloads and are not compatible with the requirements of data acquisition systems. To evaluate the use of high-performance interconnects in data acquisition systems a custom library, NetIO, is presented and compared against existing technologies. NetIO has a message queue-like interface which matches the ATLAS use case better than traditional HPC APIs like MPI. The architecture of NetIO is based on a interchangeable bac...

Volvo drivers' experiences with advanced crash avoidance and related technologies.
Eichelberger, Angela H; McCartt, Anne T
2014-01-01
Crash avoidance technologies can potentially prevent or mitigate many crashes, but their success depends in part on driver acceptance. Owners of 2010-2012 model Volvo vehicles with several technologies were interviewed about their experiences. Interviews were conducted in summer 2012 with 155 owners of vehicles with City Safety as a standard feature; 145 owners with an optional technology package that included adaptive cruise control, distance alert, collision warning with full auto brake (and pedestrian detection on certain models), driver alert control, and lane departure warning; and 172 owners with both City Safety and the technology package. The survey response rates were 21 percent for owners with City Safety, 30 percent for owners with the technology package, and 27 percent for owners with both. Ten percent of owners opted out before the telephone survey began, and 18 percent declined to participate when called. Despite some annoyance, most respondents always leave the systems on, although fewer do so for lane departure warning (59%). For each of the systems, at least 80 percent of respondents with the system would want it on their next vehicle. Many respondents reported safer driving habits with the systems (e.g., following less closely with adaptive cruise control, using turn signals more often with lane departure warning). Fewer respondents reported potentially unsafe behavior, such as allowing the vehicle to brake for them at least some of the time. About one third of respondents experienced autonomous braking when they believed they were at risk of crashing, and about one fifth of respondents thought it had prevented a crash. About one fifth of respondents with the technology package reported that they were confused or misunderstood which safety system had activated in their vehicle. Consistent with the results for early adopters in the previous survey of Volvo and Infiniti owners, the present survey found that driver acceptance of the technologies

The standard response to engineering disasters like the Deepwater Horizon case is to ascribe full moral responsibility to individuals and to collectives treated as individuals. However, this approach is inappropriate since concrete action and experience in engineering contexts seldom meets the criteria of our traditional moral theories. Technological action is often distributed rather than individual or collective, we lack full control of the technology and its consequences, and we lack knowledge and are uncertain about these consequences. In this paper, I analyse these problems by employing Kierkegaardian notions of tragedy and moral responsibility in order to account for experiences of the tragic in technological action. I argue that ascription of responsibility in engineering contexts should be sensitive to personal experiences of lack of control, uncertainty, role conflicts, social dependence, and tragic choice. I conclude that this does not justify evading individual and corporate responsibility, but inspires practices of responsibility ascription that are less 'harsh' on those directly involved in technological action, that listen to their personal experiences, and that encourage them to gain more knowledge about what they are doing. © The Author(s) 2010.

Full Text Available Though Chile is often lauded for its successful democratic transition and high quality democracy, there are increasing levels of citizen dissatisfaction with the functioning of democracy. This article asks whether this dissatisfaction is due to the lack of congruence between political elites and the mass public with respect to their orientations on political and economic issues. It provides tentative support for the proposition that there is growing consensus between elites and the mass public with respect to the most im-portant issues. Rather than a lack of congruence between elites and the mass public, the paper suggests that the more likely source of citizen dissatisfaction is an emerging partidocracia (or a polity characterized by political party domination which hampers the full functioning of democracy in terms of legitimacy, accountability and alternation of power. Because this domination has been produced by the interaction of an entrenched legislative election system and model of post-authoritarian partisan politics, it will be difficult to eliminate. A pesar de que Chile sea considerado a menudo como un caso de transición democrática exitoso y como una democracia de alta calidad, hay niveles crecientes de insatisfacción con el funcionamiento de la democracia.

Volvo and Infiniti drivers' experiences with select crash avoidance technologies.
Braitman, Keli A; McCartt, Anne T; Zuby, David S; Singer, Jeremiah
2010-06-01
Vehicle-based crash avoidance systems can potentially reduce crashes, but success depends on driver acceptance and understanding. This study gauged driver use, experience, and acceptance among early adopters of select technologies. Telephone interviews were conducted in early 2009 with 380 owners of Volvo vehicles equipped with forward collision warning with autobrake, lane departure warning, side-view assist, and/or active bi-xenon headlights and 485 owners of Infiniti vehicles with lane departure warning/prevention. Most owners kept systems turned on most of the time, especially forward collision warning with autobrake and side-view assist. The exception was lane departure prevention; many owners were unaware they had it, and the system must be activated each time the vehicle is started. Most owners reported being safer with the technologies and would want them again on their next vehicles. Perceived false or unnecessary warnings were fairly common, particularly with side-view assist. Some systems were annoying, especially lane departure warning. Many owners reported safer driving behaviors such as greater use of turn signals (lane departure warning), increased following distance (forward collision warning), and checking side mirrors more frequently (side-view assist), but some reported driving faster at night (active headlights). Despite some unnecessary or annoying warnings, most Volvo and Infiniti owners use crash avoidance systems most of the time. Among early adopters, the first requirement of effective warning systems (that owners use the technology) seems largely met. Systems requiring activation by drivers for each trip are used less often. Owner experience with the latest technologies from other automobile manufacturers should be studied, as well as for vehicles on which technologies are standard (versus optional) equipment. The effectiveness of technologies in preventing and mitigating crashes and injuries, and user acceptance of interfaces, should be

Full Text Available Na certificação de mudas de plantas frutíferas, a identificação genética é importante em todas as etapas do processo de produção. Em pessegueiro, a identificação de genótipos baseada somente em características morfofenológicas deixa dúvidas quanto à verdadeira identidade de algumas cultivares. Marcadores moleculares de microssatélies foram utilizados objetivando a caracterização molecular de 8 cultivares de nectarineira e 28 de pessegueiro. Para a análise, foram utilizados 13 incializadores de microssatélites (primers, sendo que todos foram marcadores produzindo polimorfismo suficiente para identificar 32 das 36 cultivares analisadas. A maior similaridade genética verificada nas cultivares para consumo in natura foi entre Coral e Planalto (0,94 e entre Della Nona e Marfim (0,90, enquanto, para os pessegueiros para indústria, foi de 0,93 entre Jubileu e Capdeboscq e de 0,92 entre Jade e Esmeralda. Os marcadores de microssatélites permitiram separar em grupos distintos as nectarineiras e os pessegueiros de consumo in natura dos de indústria, havendo uma elevada concordância entre os dados genealógicos das cultivares e os dados gerados pelos microssatélites, confirmando a grande utilidade da técnica para a caracterização genética.Genetic identification of fruit tree plants is important in all phases of the production process. On peach the genotypes identification based only on the morphologic and phenologic characteristics leaves doubts on the true identity of some cultivars. Microsatellite markers were used aiming at the molecular characterization of eight nectarine and 28 peach cultivars. Thirteen microsatellite primers were used and all of them generated enough polimorfism that may identify 32 out of 36 of the analysed cultivars. The greatest genetic similarity was found between the fresh market 'Coral' and 'Planalto'(0,94 and between the 'Della Nona' and 'Marfim' cultivars (0,90, whereas for caning peaches the

CIRS-lite, a Fourier Transform Spectrometer for Low-Cost Planetary Missions
Brasunas, J.; Bly, V.; Edgerton, M.; Gong, Q.; Hagopian, J.; Mamakos, W.; Morelli, A.; Pasquale, B.; Strojny, C.
2011-01-01
Passive spectroscopic remote sensing of planetary atmospheres and surfaces in the thermal infrared is a powerful tool for obtaining information about surface and atmospheric temperatures, composition, and dynamics (via the thermal wind equation). Due to its broad spectral coverage, the Fourier transform spectrometer (FTS) is particularly suited to the exploration and discovery of molecular species. NASA's Goddard Space Flight Center (GSFC) developed the CIRS (Composite Infrared Spectrometer) FTS for the NASA/ESA Cassini mission to the Saturnian system. CIRS observes Saturn, Titan, icy moons such as Enceladus, and the rings in thermal self-emission over the spectral range of 7 to 1000 ell11. CIRS has given us important new insights into stratospheric composition and jets on Jupiter and Saturn, the cryo-geyser and thermal stripes on Enceladus, and the winter polar vortex on Titan. CIRS has a mass of 43 kg, contrasted with the earlier GSFC FTS, pre-Voyager IRIS (14 kg). Future low-cost planetary missions will have very tight constraints on science payload mass, thus we must endeavor to return to IRIS-level mass while maintaining CIRS-level science capabilities ("do more with less"). CIRS-lite achieves this by pursuing: a) more sensitive infrared detectors (high Tc superconductor) to enable smaller optics. b) changed long wavelength limit from 1000 to 300 microns to reduce diffraction by smaller optics. c) CVD (chemical vapor deposition) diamond beam-splitter for broad spectral coverage. d) single FTS architecture instead of a dual FTS architecture. e) novel materials, such as single crystal silicon for the input telescope primary.

Modern Grid middleware is built around components providing basic functionality, such as data storage, authentication, security, job management, resource monitoring and reservation. In this paper we describe the Computing Resource Execution and Management (CREAM) service. CREAM provides a Web service-based job execution and management capability for Grid systems; in particular, it is being used within the gLite middleware. CREAM exposes a Web service interface allowing conforming clients to submit and manage computational jobs to a Local Resource Management System. We developed a special component, called ICE (Interface to CREAM Environment) to integrate CREAM in gLite. ICE transfers job submissions and cancellations from the Workload Management System, allowing users to manage CREAM jobs from the gLite User Interface. This paper describes some recent studies aimed at assessing the performance and reliability of CREAM and ICE; those tests have been performed as part of the acceptance tests for integration of ...

Technology for the Next-Generation-Mobile User Experience
Delagi, Greg
The current mobile-handset market is a vital and growing one, being driven by technology advances, including increased bandwidth and processing performance, as well as reduced power consumption and improved screen technologies. The 3G/4G handsets of today are multimedia internet devices with increased screen size, HD video and gaming, interactive touch screens, HD camera and camcorders, as well as incredible social, entertainment, and productivity applications. While mobile-technology advancements to date have made us more social in many ways, new advancements over the next decade will bring us to the next level, allowing mobile users to experience new types of "virtual" social interactions with all the senses. The mobile handsets of the future will be smart autonomous-lifestyle devices with a multitude of incorporated sensors, applications and display options, all designed to make your life easier and more productive! With future display media, including 3D imaging, virtual interaction and conferencing will be possible, making every call feel like you are in the same room, providing an experience far beyond today's video conferencing technology. 3D touch-screen with integrated image-projection technologies will work in conjunction with gesturing to bring a new era of intuitive mobile device applications, interaction, and information sharing. Looking to the future, there are many challenges to be faced in delivering a smart mobile companion device that will meet the user demands. One demand will be for the availability of new and compelling services, and features on the "mobile companion". These mobile companions will be more than just Internet devices, and will function as on-the-go workstations, allowing users to function as if they were sitting in front of their computer in the office or at home. The massive amounts of data that will be transmitted through, to and from these mobile companions will require immense improvements in system performance, including

Over the next three years the research program of the Heavy Ion Fusion Virtual National Laboratory (HIF-VNL), a collaboration among LBNL, LLNL, and PPPL, is focused on separate scientific experiments in the injection, transport and focusing of intense heavy ion beams at currents from 100 mA to 1 A. As a next major step in the HIF-VNL program, we aim for a complete ''source-to-target'' experiment, the Integrated Beam Experiment (IBX). By combining the experience gained in the current separate beam experiments IBX would allow the integrated scientific study of the evolution of a single heavy ion beam at high current ({approx}1 A) through all sections of a possible heavy ion fusion accelerator: the injection, acceleration, compression, and beam focusing. This paper describes the main parameters and technology choices of the planned IBX experiment. IBX will accelerate singly charged potassium or argon ion beams up to 10 MeV final energy and a longitudinal beam compression ratio of 10, resulting in a beam current at target of more than 10 Amperes. Different accelerator cell design options are described in detail: Induction cores incorporating either room temperature pulsed focusing-magnets or superconducting magnets.

RGLite, an interface between ROOT and gLite—proof on the grid
Malzacher, P.; Manafov, A.; Schwarz, K.
2008-07-01
Using the gLitePROOF package it is possible to perform PROOF-based distributed data analysis on the gLite Grid. The LHC experiments managed to run globally distributed Monte Carlo productions on the Grid, now the development of tools for data analysis is in the foreground. To grant access interfaces must be provided. The ROOT/PROOF framework is used as a starting point. Using abstract ROOT classes (TGrid, ...) interfaces can be implemented, via which Grid access from ROOT can be accomplished. A concrete implementation exists for the ALICE Grid environment AliEn. Within the D-Grid project an interface to the common Grid middleware of all LHC experiments, gLite, has been created. Therefore it is possible to query Grid File Catalogues from ROOT for the location of the data to be analysed. Grid jobs can be submitted into a gLite based Grid. The status of the jobs can be asked for, and their results can be obtained.

Explaining experience curves for new energy technologies. A case study of liquefied natural gas
International Nuclear Information System (INIS)
Greaker, Mads; Lund Sagen, Eirik
2008-01-01
Many new energy technologies seem to experience a fall in unit price as they mature. In this paper we study the unit price of liquefying natural gas in order to make it transportable by ship to gas power installations all over the world. Our point of departure is the experience curve approach, however unlike many other studies of new energy technologies, we also seek to account for autonomous technological change, scale effects and the effects of upstream competition among technology suppliers. To our surprise we find that upstream competition is by far the most important factor contributing to the fall in unit price. With respect to the natural gas business, this may have implications for the future development in prices as the effect of increased upstream competition is temporary and likely to weaken a lot sooner than effects from learning and technological change. Another more general policy implication, is that while promoting new energy technologies, governments must not forget to pay attention to competition policy. (author)

Using Inertial Sensors in Smartphones for Curriculum Experiments of Inertial Navigation Technology
Directory of Open Access Journals (Sweden)
Xiaoji Niu
2015-03-01
Full Text Available Inertial technology has been used in a wide range of applications such as guidance, navigation, and motion tracking. However, there are few undergraduate courses that focus on the inertial technology. Traditional inertial navigation systems (INS and relevant testing facilities are expensive and complicated in operation, which makes it inconvenient and risky to perform teaching experiments with such systems. To solve this issue, this paper proposes the idea of using smartphones, which are ubiquitous and commonly contain off-the-shelf inertial sensors, as the experimental devices. A series of curriculum experiments are designed, including the Allan variance test, the calibration test, the initial leveling test and the drift feature test. These experiments are well-selected and can be implemented simply with the smartphones and without any other specialized tools. The curriculum syllabus was designed and tentatively carried out on 14 undergraduate students with a science and engineering background. Feedback from the students show that the curriculum can help them gain a comprehensive understanding of the inertial technology such as calibration and modeling of the sensor errors, determination of the device attitude and accumulation of the sensor errors in the navigation algorithm. The use of inertial sensors in smartphones provides the students the first-hand experiences and intuitive feelings about the function of inertial sensors. Moreover, it can motivate students to utilize ubiquitous low-cost sensors in their future research.

Nursing care in a high-technological environment: Experiences of critical care nurses.
Tunlind, Adam; Granström, John; Engström, Åsa
2015-04-01
Management of technical equipment, such as ventilators, infusion pumps, monitors and dialysis, makes health care in an intensive care setting more complex. Technology can be defined as items, machinery and equipment that are connected to knowledge and management to maximise efficiency. Technology is not only the equipment itself, but also the knowledge of how to use it and the ability to convert it into nursing care. The aim of this study is to describe critical care nurses' experience of performing nursing care in a high technology healthcare environment. Qualitative, personal interviews were conducted during 2012 with eight critical care nurses in the northern part of Sweden. Interview transcripts were analysed using qualitative content analysis. Three themes with six categories emerged. The technology was described as a security that could facilitate nursing care, but also one that could sometimes present obstacles. The importance of using the clinical gaze was highlighted. Nursing care in a high technological environment must be seen as multi-faceted when it comes to how it affects CCNs' experience. The advanced care conducted in an ICU could not function without high-tech equipment, nor could care operate without skilled interpersonal interaction and maintenance of basal nursing. That technology is seen as a major tool and simultaneously as a barrier to patient-centred care. Copyright © 2014 Elsevier Ltd. All rights reserved.

Twenty-eight participants were interviewed using a structured interview guide and questionnaires, and a practical test of how to use the iPad was performed. The Mini-Mental State Examination (MMSE was used to assess cognition. Cognitive deficits and low self-efficacy significantly reduced the ability of the subjects to use the smart house technology and to perceive the smart house technology service as provided. Age was unrelated to the outcome variables. Finally, technology experience had an effect on technology perception. If further research supports these findings, it should influence smart-house implementation in an elderly population, raising awareness of usability problems in older people with low self-efficacy and cognitive problems.Keywords: smart house technology, iPad, cognition, self-efficacy, technology experience, elderly

This paper describes a space solar cell experiment currently being built by the Naval Research Laboratory (NRL) in collaboration with NASA Glenn Research Center (GRC), and the US Naval Academy (USNA). The experiment has been named the Forward Technology Solar Cell Experiment (FTSCE), and the purpose is to rapidly put current and future generation space solar cells on orbit and provide validation data for these technologies. The FTSCE is being fielded in response to recent on-orbit and ground test anomalies associated with space solar arrays that have raised concern over the survivability of new solar technologies in the space environment and the validity of present ground test protocols. The FTSCE is being built as part of the Fifth Materials on the International Space Station (MISSE) Experiment (MISSE-5), which is a NASA program to characterize the performance of new prospective spacecraft materials when subjected to the synergistic effects of the space environment. Telemetry, command, control, and communication (TNC) for the FTSCE will be achieved through the Amateur Satellite Service using the PCSat2 system, which is an Amateur Radio system designed and built by the USNA. In addition to providing an off-the-shelf solution for FTSCE TNC, PCSat2 will provide a communications node for the Amateur Radio satellite system. The FTSCE and PCSat2 will be housed within the passive experiment container (PEC), which is an approximately 2ft x2ft x 4in metal container built by NASA Langley Research Center (NASA LaRC) as part of the MISSE-5 program. NASA LaRC has also supplied a thin film materials experiment that will fly on the exterior of the thermal blanket covering the PCSat2. The PEC is planned to be transported to the ISS on a Shuttle flight. The PEC will be mounted on the exterior of the ISS by an astronaut during an extravehicular activity (EVA). After nominally one year, the PEC will be retrieved and returned to Earth. At the time of writing this paper, the

Application of Ifsar Technology in Topographic Mapping: JUPEM's Experience
Zakaria, Ahamad
2018-05-01
The application of Interferometric Synthetic Aperture Radar (IFSAR) in topographic mapping has increased during the past decades. This is due to the advantages that IFSAR technology offers in solving data acquisition problems in tropical regions. Unlike aerial photography, radar technology offers wave penetration through cloud cover, fog and haze. As a consequence, images can be made free of any natural phenomenon defects. In Malaysia, Department of Survey and Mapping Malaysia (JUPEM) has been utilizing the IFSAR products since 2009 to update topographic maps at 1 : 50,000 map scales. Orthorectified radar imagery (ORI), Digital Surface Models (DSM) and Digital Terrain Models (DTM) procured under the project have been further processed before the products are ingested into a revamped mapping workflow consisting of stereo and mono digitizing processes. The paper will highlight the experience of Department of Survey and Mapping Malaysia (DSMM)/ JUPEM in using such technology in order to speed up mapping production.

Adicionalmente, estas pueden ser caracterizadas con datos provenientes del espacio de la misma manera en que son caracterizadas las estaciones insitu procurando información de carácter hidráulico (pendiente del fondo del cauce, profundidad del flujo cero, coeficiente de Manning, entre otros que hasta el momento sólo podía ser deducida a partir de mediciones directas en campo.

Full Text Available En las décadas comprendidas entre 1982 y 2002, Colombia ya se afirmaba como un Estado democrático. Sin embargo, en este período el paramilitarismo agenció uno de los más agudos niveles de violencia homicida en el país. Ante esta realidad incuestionable, surgen planteamientos que intentan explicar esta paradoja: a Colombia no es una democracia: es un régimen terrorista que acaba con la oposición para mantener un sistema de exclusiones desde arriba; b las instituciones colombianas han sido una víctima más de la violencia paramilitar; y c el paramilitarismo obedece a la insurgencia de élites locales y regionales contra procesos de paz impulsados desde arriba. Las dos primeras, claramente cuestionables. La última, todavía insuficiente a la hora de identificar el papel de los tomadores de decisiones a nivel central, tanto en el Estado como en el sistema político, en el despliegue y auge del fenómeno paramilitar. Este artículo evalúa estas tres afirmaciones y analiza, con base en documentos oficiales e informes de prensa de la época, los alcances del paramilitarismo en las décadas comprendidas entre 1982 y 2002, al tenor del papel desempeñado por la democracia colombiana y sus instituciones, pues –al contrario del discurso oficial de los gobiernos, quienes por más de treinta años han afirmado haber sufrido la penetración y agresión del paramilitarismo de la mano de “manzanas podridas” o “casos aislados”– el fenómeno paramilitar en Colombia durante el período estudiado disfrutó de un estatus especial agenciado públicamente por políticos centristas, prosaicos y conciliadores apuntalados en las presiones de sectores clave del sistema político y de las élites vulnerables del país.

Internet Filtering Technology and Aversive Online Experiences in Adolescents.
Przybylski, Andrew K; Nash, Victoria
2017-05-01
To evaluate the effectiveness of Internet filtering tools designed to shield adolescents from aversive experiences online. A total of 1030 in-home interviews were conducted with early adolescents aged from 12 to 15 years (M = 13.50, SD = 1.18) and their caregivers. Caregivers were asked about their use of Internet filtering and adolescent participants were interviewed about their recent online experiences. Contrary to our hypotheses, policy, and industry advice regarding the assumed benefits of filtering we found convincing evidence that Internet filters were not effective at shielding early adolescents from aversive online experiences. Preregistered prospective and randomised controlled trials are needed to determine the extent to which Internet filtering technology supports vs thwarts young people online and if their widespread use justifies their financial and informational costs.

US monitoring and verification technology: on-site inspection experience and future challenges
International Nuclear Information System (INIS)
Gullickson, R.L.; Carlson, D.; Ingraham, J.; Laird, B.
2013-01-01
The United States has a long and successful history of cooperation with treaty partners in monitoring and verification. For strategic arms reduction treaties, our collaboration has resulted in the development and application of systems with limited complexity and intrusiveness. As we progress beyond New START (NST) along the 'road to zero', the reduced number of nuclear weapons is likely to require increased confidence in monitoring and verification techniques. This may place increased demands on the technology to verify the presence of a nuclear weapon and even confirm the presence of a certain type. Simultaneously, this technology must include the ability to protect each treaty partner's sensitive nuclear weapons information. Mutual development of this technology by treaty partners offers the best approach for acceptance in treaty negotiations. This same approach of mutual cooperation and development is essential for developing nuclear test monitoring technology in support of the Comprehensive Nuclear Test Ban Treaty (CTBT). Our ability to detect low yield and evasive testing will be enhanced through mutually developed techniques and experiments using laboratory laser experiments and high explosives tests in a variety of locations and geologies.

A design for living technology: experiments with the mind time machine.
Ikegami, Takashi
2013-01-01
Living technology aims to help people expand their experiences in everyday life. The environment offers people ways to interact with it, which we call affordances. Living technology is a design for new affordances. When we experience something new, we remember it by the way we perceive and interact with it. Recent studies in neuroscience have led to the idea of a default mode network, which is a baseline activity of a brain system. The autonomy of artificial life must be understood as a sort of default mode that self-organizes its baseline activity, preparing for its external inputs and its interaction with humans. I thus propose a method for creating a suitable default mode as a design principle for living technology. I built a machine called the mind time machine (MTM), which runs continuously for 10 h per day and receives visual data from its environment using 15 video cameras. The MTM receives and edits the video inputs while it self-organizes the momentary now. Its base program is a neural network that includes chaotic dynamics inside the system and a meta-network that consists of video feedback systems. Using this system as the hardware and a default mode network as a conceptual framework, I describe the system's autonomous behavior. Using the MTM as a testing ground, I propose a design principle for living technology.

Experience with virtual reality-based technology in teaching restorative dental procedures.
Buchanan, Judith A
2004-12-01
This article reports on extensive experience with advanced simulation at the University of Pennsylvania, School of Dental Medicine (UPSDM). Virtual reality-based technology (VRBT) or advanced simulation is currently available for the instruction of dental students in preclinical restorative procedures. UPSDM was one of the first schools in the world to have extensive experience with VRBT technology using an advanced simulation unit (DentSim) from DenX, Ltd. UPSDM's experience consists of several years of research using control and experimental groups, employing students to participate in an investigative project, and using the units for remediation and a supplement to the preclinical laboratory. Currently, all first-year students (Class of 2007 and Class of 2008) are receiving most of their preparative operative training on the VRBT units. UPSDM started with one (beta) version unit in 1998, which was later updated and expanded first to four units and recently to fifteen units. This communication is presenting the studies that were of fundamental importance in making the decision to acquire fifteen units in 2003. The areas of main interest to the SDM concerning this technology were its use in teaching, refreshing, and remediating students in restorative procedures and its effectiveness as a teaching methodology in relation to time, efficiency, and faculty. Several studies with varying parameters were performed at various time points. The limited statistical analysis conducted was not conclusive for all measures, and in some cases the data only suggest areas of possible significance. This is due to the low number of students who could access the limited number of available units and the change of protocols in response to student and faculty input. Overall, the results do suggest, however, that students learn faster, arrive at the same level of performance, accomplish more practice procedures per hour, and request more evaluations per procedure or per hour than in our

The large helical device is a heliotron device with L = 2 and M = 10 continuous helical coils and three pairs of poloidal coils, and all of coils are superconductive. Since the experiments started in 1998, the development of engineering technologies and the demonstration of large-superconducting-machine operations have greatly contributed to an understanding of physics in currentless plasmas and a verification of the capability of fully steady-state operation. In recent plasma experiments, the steady state and high-beta experiments, which are the most important subjects for the realization of attractive fusion reactors, have progressed remarkably and produced two world-record parameters, i.e. the highest average beta of 4.5% in helical devices and the highest total input energy of 1.6 GJ in all magnetic confinement devices. No degradation has been observed in the coil performance, and stable cryogenic operational schemes at 4.4 K have been established. The physics and engineering results from the LHD experiment directly contribute to the design study for a D-T fusion demo reactor FFHR with a LHD-type heliotron configuration

The tremendous growth in biological data has resulted in an increase in the number of research papers being published. This presents a great challenge for scientists in searching and assimilating facts described in those papers. Particularly, biological databases depend on curators to add highly precise and useful information that are usually extracted by reading research articles. Therefore, there is an urgent need to find ways to improve linking literature to the underlying data, thereby minimising the effort in browsing content and identifying key biological concepts. As part of the development of Europe PMC, we have developed a new platform, SciLite, which integrates text-mined annotations from different sources and overlays those outputs on research articles. The aim is to aid researchers and curators using Europe PMC in finding key concepts more easily and provide links to related resources or tools, bridging the gap between literature and biological data.

Technology of mirror machines: LLL facilities for magnetic mirror fusion experiments
International Nuclear Information System (INIS)
Batzer, T.H.
1977-01-01
Significant progress in plasma confinement and temperature has been achieved in the 2XIIB facility at Livermore. These encouraging results, and their theoretical corroboration, have provided a firm basis for the design of a new generation of magnetic mirror experiments, adding support to the mirror concept of a fusion reactor. Two new mirror experiments have been proposed to succeed the currently operating 2XIIB facility. The first of these called TMX (Tandem Mirror Experiment) has been approved and is currently under construction. TMX is designed to utilize the intrinsic positive plasma potential of two strong, and relatively small, minimum B mirror cells to enhance the confinement of a much larger, magnetically weaker, centrally-located mirror cell. The second facility, MFTF (Mirror Fusion Test Facility), is currently in preliminary design with line item approval anticipated for FY 78. MFTF is designed primarily to exploit the experimental and theoretical results derived from 2XIIB. Beyond that, MFTF will develop the technology for the transition from the present small mirror experiments to large steady-state devices such as the mirror FERF/FTR. The sheer magnitude of the plasma volume, magnetic field, neutral beam power, and vacuum pumping capacity, particularly in the case of MFTF, has placed new and exciting demands on engineering technology. An engineering overview of MFTF, TMX, and associated MFE activities at Livermore will be presented

Over the next three years the research program of the Heavy Ion Fusion Virtual National Laboratory (HIF-VNL), a collaboration among LBNL, LLNL, and PPPL, is focused on separate scientific experiments in the injection, transport and focusing of intense heavy ion beams at currents from 100 mA to 1 A. As a next major step in the HIF-VNL program, we aim for a complete 'source-to-target' experiment, the Integrated Beam Experiment (IBX). By combining the experience gained in the current separate beam experiments IBX would allow the integrated scientific study of the evolution of a single heavy ion beam at high current (∼1 A) through all sections of a possible heavy ion fusion accelerator: the injection, acceleration, compression, and beam focusing.This paper describes the main parameters and technology choices of the planned IBX experiment. IBX will accelerate singly charged potassium or argon ion beams up to 10 MeV final energy and a longitudinal beam compression ratio of 10, resulting in a beam current at target of more than 10 Amperes. Different accelerator cell design options are described in detail: Induction cores incorporating either room temperature pulsed focusing-magnets or superconducting magnets

The use of technology into science learning encounters problems. One of the problem is teachers’ less technological pedagogical and content knowledge (TPACK) on the implementation of technology itself. The purpose of this study was to investigate science teachers’ experience in using digital technology into science classroom. Through this study science teachers’ technological knowledge (TK) and technological content knowledge (TCK) can be unpacked. Descriptive method was used to depict science teachers’ TK and TCK through questionnaire that consisted of 20 questions. Subjects of this study were 25 science teachers in Bandung, Indonesia. The study was conducted in the context of teacher professional training. Result shows that science teachers still have less TK, yet they have high TCK. The teachers consider characteristics of concepts as main aspect for implementing technology into science teaching. This finding describes teachers’ high technological content knowledge. Meanwhile, science teachers’ technological knowledge was found to be still low since only few of them who can exemplify digital technology that can be implemented into several science concept. Therefore, training about technology implementation into science teaching and learning is necessary as a means to improve teachers’ technological knowledge.

Smart house technology using tablet computers may help older people to master activities of daily living by making it easier to perform daily tasks like controlling lights and indoor temperature throughout the house with a few keystrokes. The aim of this study was to investigate the impact of age, cognition, self-efficacy, and technology experience on the ability of older people to perceive and use iPad tablet computers for this purpose. Twenty-eight participants were interviewed using a structured interview guide and questionnaires, and a practical test of how to use the iPad was performed. The Mini-Mental State Examination (MMSE) was used to assess cognition. Cognitive deficits and low self-efficacy significantly reduced the ability of the subjects to use the smart house technology and to perceive the smart house technology service as provided. Age was unrelated to the outcome variables. Finally, technology experience had an effect on technology perception. If further research supports these findings, it should influence smart-house implementation in an elderly population, raising awareness of usability problems in older people with low self-efficacy and cognitive problems.

Older individuals' experiences during the assistive technology device service delivery process.
Gramstad, Astrid; Storli, Sissel Lisa; Hamran, Torunn
2014-07-01
Providing assistive technology devices to older individuals living in their ordinary homes is an important intervention to increase and sustain independence and to enable ageing at home. However, little is known about older individuals' experiences and needs in the assistive technology device (ATD) service delivery process. The purpose of this study was to investigate older individuals' experiences during the service delivery process of ATDs. Nine older individuals were interviewed three times each throughout the ATD service delivery process. The interviews were analysed within a hermeneutical phenomenological perspective. The results show that the service delivery process could be interpreted as an enigmatic journey and described using four themes: "hope and optimistic expectations", "managing after delivery or needing additional help", "having available help versus being abandoned", and "taking charge or putting up". The results emphasize the need for occupational therapists to maintain an individualized approach towards older clients throughout the service delivery process. The experiences of older individuals were diverse and related to expectations that were not necessarily articulated to the occupational therapist. The situation when the ATD is delivered to the client was highlighted by the clients as an important event with the potential to facilitate a successful service delivery process.

``Recent experiences and future expectations in data storage technology''
Pfister, Jack
1990-08-01
For more than 10 years the conventional media for High Energy Physics has been 9 track magnetic tape in various densities. More recently, especially in Europe, the IBM 3480 technology has been adopted while in the United States, especially at Fermilab, 8 mm is being used by the largest experiments as a primary recording media and where possible they are using 8 mm for the production, analysis and distribution of data summary tapes. VHS and Digital Audio tape have recurrently appeared but seem to serve primarily as a back-up storage media. The reasons for what appear to be a radical departure are many. Economics (media and controllers are inexpensive), form factor (two gigabytes per shirt pocket), and convenience (fewer mounts/dismounts per minute) are dominant among the reasons. The traditional data media suppliers seem to have been content to evolve the traditional media at their own pace with only modest enhancements primarily in ``value engineering'' of extant products. Meanwhile, start-up companies providing small system and workstations sought other media both to reduce the price of their offerings and respond to the real need of lower cost back-up for lower cost systems. This happening in a market context where traditional computer systems vendors were leaving the tape market altogether or shifting to ``3480'' technology which has certainly created a climate for reconsideration and change. The newest data storage products, in most cases, are not coming from the technologies developed by the computing industry but by the audio and video industry. Just where these flopticals, opticals, 19 mm tape and the new underlying technologies, such as, ``digital paper'' may fit in the HEP computing requirement picture will be reviewed. What these technologies do for and to HEP will be discussed along with some suggestions for a methodology for tracking and evaluating extant and emerging technologies.

Experience with a run file archive using database technology
International Nuclear Information System (INIS)
Nixdorf, U.
1993-12-01
High Energy Physics experiments are known for their production of large amounts of data. Even small projects may have to manage several Giga Byte of event information. One possible solution for the management of this data is to use today's technology to archive the raw data files in tertiary storage and build on-line catalogs which reference interesting data. This approach has been taken by the Gammas, Electrons and Muons (GEM) Collaboration for their evaluation of muon chamber technologies at the Superconducting Super Collider Laboratory (SSCL). Several technologies were installed and tested during a 6 month period. Events produced were first recorded in the UNIX filesystem of the data acquisition system and then migrated to the Physics Detector Simulation Facility (PDSF) for long term storage. The software system makes use of a commercial relational database management system (SYBASE) and the Data Management System (DMS), a tape archival system developed at the SSCL. The components are distributed among several machines inside and outside PDSF. A Motif-based graphical user interface (GUI) enables physicists to retrieve interesting runs from the archive using the on-line database catalog

The impact of foundry-to-foundry variability and bias conditions during irradiation on the Total Ionizing Dose (TID) response of commercial 130-nm CMOS technologies have been investigated for applications in High Energy Physics (HEP) experiments. n- and p-channel MOSFETs from three different manufacturers have been irradiated with X-rays up to more than 100 Mrad (SiO2). Even though the effects of TID are qualitatively similar, the amount of degradation is shown to vary considerably from foundry to foundry, probably depending on the processing of the STI oxide and/or doping profile in the substrate. The bias during irradiation showed to have a strong impact as well on the TID response, proving that exposure at worst case bias conditions largely overestimates the degradation a device may experience during its lifetime. Overall, our results increase the confidence that 130-nm CMOS technologies can be used in future HEP experiments even without Hardness-By-Design solutions, provided that constant monitoring of th...

A 3-month-long, large-scale flume experiment involving research and testing of selected conventional and surrogate bedload-monitoring technologies was conducted in the Main Channel at the St. Anthony Falls Laboratory under the auspices of the National Center for Earth-surface Dynamics. These experiments, dubbed StreamLab06, involved 25 researchers and volunteers from academia, government, and the private sector. The research channel was equipped with a sediment-recirculation system and a sediment-flux monitoring system that allowed continuous measurement of sediment flux in the flume and provided a data set by which samplers were evaluated. Selected bedload-measurement technologies were tested under a range of flow and sediment-transport conditions. The experiment was conducted in two phases. The bed material in phase I was well-sorted siliceous sand (0.6-1.8 mm median diameter). A gravel mixture (1-32 mm median diameter) composed the bed material in phase II. Four conventional bedload samplers – a standard Helley-Smith, Elwha, BLH-84, and Toutle River II (TR-2) sampler – were manually deployed as part of both experiment phases. Bedload traps were deployed in study Phase II. Two surrogate bedload samplers – stationarymounted down-looking 600 kHz and 1200 kHz acoustic Doppler current profilers – were deployed in experiment phase II. This paper presents an overview of the experiment including the specific data-collection technologies used and the ambient hydraulic, sediment-transport and environmental conditions measured as part of the experiment. All data collected as part of the StreamLab06 experiments are, or will be available to the research community.

Technology foresight studies have become an important tool in identifying realistic ways of reducing the impact of modern energy systems on the climate and the environment. Studies on the future cost development of advanced energy technologies are of special interest. One approach widely adopted for the analysis of future cost is the experience curve approach. The question is, however, how robust this approach is, and which experience curves should be used in energy foresight analysis. This paper presents an analytical framework for the analysis of future cost development of new energy technologies for electricity generation; the analytical framework is based on an assessment of available experience curves, complemented with bottom-up analysis of sources of cost reductions and, for some technologies, judgmental expert assessments of long-term development paths. The results of these three methods agree in most cases, i.e. the cost (price) reductions described by the experience curves match the incremental cost reduction described in the bottom-up analysis and the judgmental expert assessments. For some technologies, the bottom-up analysis confirms large uncertainties in future cost development not captured by the experience curves. Experience curves with a learning rate ranging from 0% to 20% are suggested for the analysis of future cost development

In this paper, the gasification conditions, the gasifier structure, the measuring system and the gasification rationale of a pilot project experiment of underground coal gasification (UCG) in the Liuzhuang Colliery, Tangshan, are illustrated. The technique of two-phase underground coal gasification is proposed. The detection of the moving speed and the length of the gasification working face is made using radon probing technology. An analysis of the experiment results indicates that the output of air gas is 3000 m 3 /h with a heating value of about 4.18 MJ/m 3 , while the output of water gas is 2000 m 3 /h with a heating value of over 11.00 MJ/m 3 , of which H 2 content is above 40% with a maximum of 71.68%. The cyclical time of two-phase underground gasification is 16 h, with 8 h for each phase. This prolongs the time when the high-heating value gas is produced. The moving speed of the gasification working face in two alternative gasifiers is identified, i.e. 0.204 and 0.487 m/d, respectively. The success of the pilot project experiment of the underground gasification reveals the strides that have been made toward the commercialization of the UCG in China. It also further justifies the reasonability and feasibility of the new technology of long channel, big section, two-phase underground gasification. A conclusion is also drawn that the technology of the pilot project experiment can be popularized in old and discarded coal mines

New tools and technology for the study of human performance in simulator experiments
International Nuclear Information System (INIS)
Droeivoldsmo, Asgeir
2004-04-01
The Halden Virtual Reality Centre has for the last four years reported a number of experiments in the area of real world application of virtual and augmented reality technology. The insights from these studies have been reviewed and reported as part of a PhD-thesis submitted at the Norwegian University of Science and Technology. This report is based on the thesis and contains a theoretical discussion of how the virtual and augmented reality technology could be used to extend human operator performance in control rooms to include co-operation with plant floor personnel and interaction with not already built equipment. This thesis suggests that new tools and technology can be used for production of relevant data and insights from the study of human performance in simulator and field experiments. It examines some of the theoretical perspectives behind data collection and human performance assessment, and argues for a high resemblance of the real world and use of subject matter expertise in simulator studies. A model is proposed, suggesting that human performance measurement should be tightly coupled to the topic of study and have a close connection to the time line. This coupling requires new techniques for continuous data collection, and eye movement tracking has been identified as a promising basis for this type of measures. One way of improving realism is to create virtual environments allowing for controlling more of the environment surrounding the test subjects. New application areas for virtual environments are discussed for use in control room and field studies. The combination of wearable computing, virtual and augmented (the use of computers to overlay virtual information onto the real world) reality provides many new possibilities to present information to operators. In two experiments, virtual and augmented reality techniques were used to visualise radiation fields for operators in a contaminated nuclear environment. This way the operators could train for

Students' Perceptions of and Experiences With Educational Technology: A Survey.
Royal, Kenneth; Hedgpeth, Mari-Wells; McWhorter, Dan
2016-05-18
It is generally assumed that incoming students in medical education programs will be better equipped for the "digital age" given their younger age and an educational upbringing in which technology was seemingly omnipresent. In particular, many assume that today's medical students are more likely to hold positive attitudes and increased comfortability with technology and possess greater information technology (IT) skills. The purpose of this study was to compare responses of incoming veterinary medical students to a series of IT-related questions contained in a common questionnaire over the course of a 10-year period (2005-2015) to discern whether students' attitudes have improved and uses and comfortability with technology have increased as anticipated. A survey measuring attitudes and preferences, computing experience, and technology ownership was administered each year for the past 10 years to incoming veterinary medical students at a large veterinary school in the United States. Students' responses to survey items were compared at 3 data points (2005, 2010, and 2015). Today's incoming veterinary medical students tend to indicate the same desire to improve skills using spreadsheets and web page design as incoming students from 10 years ago. It seems that despite technological advances and increased exposure to such applications and skills, there remains a challenge for students to "keep up" with the ever evolving technology. Moreover, although students continue to report they are very comfortable with using a computer (and related devices), many use their computers as typewriters or word processors, as opposed to a means for performing more advanced computing functions. In general, today's medical students are not expert computer users as many assume. Despite an upbringing in a digitized world, many students still lack many basic computing skills.

The potential for digital technologies to enhance students' mathematics learning is widely recognised, and use of computers and graphics calculators is now encouraged or required by secondary school mathematics curriculum documents throughout Australia. However, previous research indicates that effective integration of technology into classroom practice remains patchy, with factors such as teacher knowledge, confidence, experience and beliefs, access to resources, and participation in professional development influencing uptake and implementation. This paper reports on a large-scale survey of technology-related professional development experiences and needs of Queensland secondary mathematics teachers. Teachers who had participated in professional development were found to be more confident in using technology and more convinced of its benefits in supporting students' learning of mathematics. Experienced, specialist mathematics teachers in large metropolitan schools were more likely than others to have attended technology-related professional development, with lack of time and limited access to resources acting as hindrances to many. Teachers expressed a clear preference for professional development that helps them meaningfully integrate technology into lessons to improve student learning of specific mathematical topics. These findings have implications for the design and delivery of professional development that improves teachers' knowledge, understanding, and skills in a diverse range of contexts.

Selected issues in the development of fusion nuclear technology (FNT) have been studied. These relate to (1) near-term experiments, modeling, and analysis for several key FNT issues, and (2) FNT testing in future fusion facilities. A key concern for solid breeder blankets is to reduce the number of candidate materials and configurations for advanced experiments to emphasize those with the highest potential. Based on technical analysis, recommendations have been developed for reducing the size of the test matrix and for focusing the testing program on important areas of emphasis. The characteristics of an advanced liquid metal MHD experiment have also been studied. This facility is required in addition to existing facilities in order to address critical uncertainties in MHD fluid flow and heat transfer. In addition to experiments, successful development of FNT will require models for interpreting experimental data, for planning experiments, and for use as a design tool for fusion components. Modeling of liquid metal fluid flows is a particular area of need in which substantial progress is expected, and initial efforts are reported here. Preliminary results on the modeling of tritium transport and inventory in solid breeders are also summarized. Finally, the thermo-mechanical behavior of liquid-metal-cooled limiters is analyzed and the parameter space for feasible designs is explored. Because of the renewed strong interest in a fusion engineering facility, a critical review and analysis of the important FNT testing requirements have been performed. Several areas have been emphasized due to their strong impact on the design and cost of the test facility. These include (1) the length of the plasma burn and the mode of operation (pulsed vs. steady-state), and (2) the need for a tritium-producing blanket and its impact on the availability of the device.

Several public health education programs and government agencies across the country have started offering virtual or online training programs in emergency preparedness for people who are likely to be involved in managing or responding to different types of emergency situations such as natural disasters, epidemics, bioterrorism, etc. While such online training programs are more convenient and cost-effective than traditional classroom-based programs, their success depends to a great extent on the underlying technological environment. Specifically, in an online technological environment, different types of user experiences come in to play-users' utilitarian or pragmatic experience, their fun or hedonic experience, their social experience, and most importantly, their usability experience-and these different user experiences critically shape the program outcomes, including course completion rates. This study adopts a multi-disciplinary approach and draws on theories in human computer interaction, distance learning theories, usability research, and online consumer behavior to evaluate users' experience with the technological environment of an online emergency preparedness training program and discusses its implications for the design of effective online training programs. . Data was collected using a questionnaire from 377 subjects who had registered for and participated in online public health preparedness training courses offered by a large public university in the Northeast. Analysis of the data indicates that as predicted, participants had higher levels of pragmatic and usability experiences compared to their hedonic and sociability experiences. Results also indicate that people who experienced higher levels of pragmatic, hedonic, sociability and usability experiences were more likely to complete the course(s) they registered for compared to those who reported lower levels. The study findings hold important implications for the design of effective online emergency

Crash avoidance technologies have the potential to prevent or mitigate many crashes, but their effectiveness depends on drivers' acceptance and proper use. Owners of 2011 Dodge Charger, Dodge Durango, and Jeep Grand Cherokee vehicles were interviewed about their experiences with their vehicles' technologies. Interviews were conducted in April 2013 with 215 owners of Dodge and Jeep vehicles with adaptive cruise control and forward collision warning and 215 owners with blind spot monitoring and rear cross-path detection. Most owners said that they always keep each collision avoidance technology turned on, and more than 90% of owners with each system would want the technology again on their next vehicle. The majority believed that the systems had helped prevent a collision; this ranged from 54% of drivers with forward collision warning to more than three-quarters with blind spot monitoring and rear cross-path detection. Some owners reported behavioral changes with the systems, but over-reliance on them is not prevalent. Reported use of the systems varied by the age and gender of the driver and duration of vehicle ownership to a greater degree than in previous surveys of luxury Volvo and Infiniti vehicles with collision avoidance technologies. Notably, drivers aged 40 and younger were most likely to report that forward collision warning had alerted them multiple times and that it had prevented a collision and that they follow the vehicle ahead less closely with adaptive cruise control. Reports of waiting for the alert from forward collision warning before braking were infrequent but increased with duration of ownership. However, these reports could reflect confusion of the system with adaptive cruise control, which alerts drivers when braking is necessary to maintain a preset speed or following distance but a crash is not imminent. Consistent with previous surveys of luxury vehicle owners with collision avoidance technologies, acceptance and use remains high among

The Forward Technology Solar Cell Experiment (FTSCE) is a space solar cell experiment built as part of the Fifth Materials on the International Space Station Experiment (MISSE-5): Data Acquisition and Control Hardware and Software. It represents a collaborative effort between the NASA Glenn Research Center, the Naval Research Laboratory, and the U.S. Naval Academy. The purpose of this experiment is to place current and future solar cell technologies on orbit where they will be characterized and validated. This is in response to recent on-orbit and ground test results that raised concerns about the in-space survivability of new solar cell technologies and about current ground test methodology. The various components of the FTSCE are assembled into a passive experiment container--a 2- by 2- by 4-in. folding metal container that will be attached by an astronaut to the outer structure of the International Space Station. Data collected by the FTSCE will be relayed to the ground through a transmitter assembled by the U.S. Naval Academy. Data-acquisition electronics and software were designed to be tolerant of the thermal and radiation effects expected on orbit. The experiment has been verified and readied for flight on STS-114.

mHealth apps are deployed with the aim of improving access, quality, and experience of health care. It is possible that any mHealth intervention can yield differential impacts for different types of users. Mediating and determining factors, including personal and socioeconomic factors, affect technology adoption, the way health workers leverage and use the technology, and subsequently the quality and experience of care they provide. To develop a framework to assess whether mHealth platforms affect the quality and experience of care provided by frontline workers, and whether these effects on quality and experience are different depending on the level of technology adoption and individual characteristics of the health worker. Literacy, education, age, and previous mobile experience are identified as individual factors that affect technology adoption and use, as well as factors that affect the quality and experience of care directly and via the technology. Formative research was conducted with 15 community health workers (CHWs) using CommCare, an mHealth app for maternal and newborn care, in Bihar, India. CHWs were first classified on the level of CommCare adoption using data from CommCareHQ and were then shadowed on home visits to evaluate their levels of technology proficiency, and the quality and experience of care provided. Regression techniques were employed to test the relationships. Out of all the CHWs, 2 of them refused to participate in the home visits, however, we did have information on their levels of technology adoption and background characteristics, which were included in the analysis as relevant. Level of technology adoption was important for both quality and experience of care. The quality score for high users of CommCare was higher by 33.4% (P=.04), on average, compared to low users of CommCare. Those who scored higher on CommCare proficiency also provided significantly higher quality and experience of care, where an additional point in Comm

This study examines the role of video technology in the development of cooking skills. The study explored the views of 141 female participants on whether video technology can promote confidence in learning new cooking skills to assist in meal preparation. Prior to each focus group participants took part in a cooking experiment to assess the most effective method of learning for low-skilled cooks across four experimental conditions (recipe card only; recipe card plus video demonstration; recipe card plus video demonstration conducted in segmented stages; and recipe card plus video demonstration whereby participants freely accessed video demonstrations as and when needed). Focus group findings revealed that video technology was perceived to assist learning in the cooking process in the following ways: (1) improved comprehension of the cooking process; (2) real-time reassurance in the cooking process; (3) assisting the acquisition of new cooking skills; and (4) enhancing the enjoyment of the cooking process. These findings display the potential for video technology to promote motivation and confidence as well as enhancing cooking skills among low-skilled individuals wishing to cook from scratch using fresh ingredients.

Education in hydrology is changing rapidly due to diversification of students, emergent major scientific and practical challenges that our discipline must engage with, shifting pedagogic ideas and higher education environments, the need for students to develop new discipline specific and transferrable skills, and the advent of innovative technologies for learning and teaching. This paper focuses on new technologies in the context of learning and teaching in Physical Geography and reflects on the implications of our experiences for education in hydrology. We evaluate the experience of designing and trialling novel mobile technology-based field exercises and a virtual field trip for a Year 1 undergraduate Physical Geography module at a UK university. The new exercises are based on using and obtaining spatial data, operation of meteorological equipment (explained using an interactive DVD), and include introductions to global positioning systems (GPS) and geographical information systems (GIS). The technology and exercises were well received in a pilot study and subsequent rolling-out to the full student cohort (∼150 students). A statistically significant improvement in marks was observed following the redesign. Although the students enjoyed using mobile technology, the increased interactivity and opportunity for peer learning were considered to be the primary benefits by students. This is reinforced further by student preference for the new interactive virtual field trip over the previous "show-and-tell" field exercise. Despite the new exercises having many advantages, exercise development was not trivial due to the high start-up costs, the need for provision of sufficient technical support and the relative difficulty of making year-to-year changes (to the virtual field trip in particular). We believe our experiences are directly relevant to the implementation of such novel learning and teaching technologies in hydrology education.

This work presents a methodology for constructing 2D estimates of CO2 field concentrations from integrated open path measurements of CO2 concentrations. It provides a description of the methodology, an assessment based on simulated data and results from preliminary field trials. The Greenhouse gas Laser Imaging Tomography Experiment (GreenLITE) system, currently under development by Exelis and AER, consists of a set of laser-based transceivers and a number of retro-reflectors coupled with a cloud-based compute environment to enable real-time monitoring of integrated CO2 path concentrations, and provides 2D maps of estimated concentrations over an extended area of interest. The GreenLITE transceiver-reflector pairs provide laser absorption spectroscopy (LAS) measurements of differential absorption due to CO2 along intersecting chords within the field of interest. These differential absorption values for the intersecting chords of horizontal path are not only used to construct estimated values of integrated concentration, but also employed in an optimal estimation technique to derive 2D maps of underlying concentration fields. This optimal estimation technique combines these sparse data with in situ measurements of wind speed/direction and an analytic plume model to provide tomographic-like reconstruction of the field of interest. This work provides an assessment of this reconstruction method and preliminary results from the Fall 2014 testing at the Zero Emissions Research and Technology (ZERT) site in Bozeman, Montana. This work is funded in part under the GreenLITE program developed under a cooperative agreement between Exelis and the National Energy and Technology Laboratory (NETL) under the Department of Energy (DOE), contract # DE-FE0012574. Atmospheric and Environmental Research, Inc. is a major partner in this development.

The Laser Initiated Target Experiment (LITE) at the United Technologies Research Center is designed to address the target plasma buildup approach to a steady state mirror fusion device. A dense, mirror confined, target plasma is produced by high power laser irradiation of a solid lithium hydride particle, electrically suspended in a vacuum at the center of an established minimum-B magnetic field. Following expansion in and capture by the magnetic field, this target plasma is irradiated by an energetic neutral hydrogen beam. Charge exchange collisions with energetic beam particles serve to heat the confined plasma while ionization of the neutral beam atoms and trapping in the mirror magnetic field add particles to the confined plasma. For sufficiently high beam intensities, confined plasmas losses will be offset so that buildup of the plasma density occurs, thus demonstrating sustenance and fueling as well as the heating by neutral beam injection of a steady state mirror fusion device. Investigations of the decay of the magnetically confined target plasmas and initial studies of energetic neutral beam injection into confined target plasmas, conducted during this report period, are presented. Additional development of the LITE experimental systems including improvements in the laser plasma production facility, the energetic neutral beam line, and the heavy ion probe diagnostic is reported. A series of calculations on enhanced scattering and classical decay for plasma mirror confined in a LITE type system are discussed

This multicenter study was conducted to evaluate the performance of five recently introduced blood glucose (BG) monitoring (BGM) devices under daily routine conditions in comparison with the YSI (Yellow Springs, OH) 2300 Stat Plus glucose analyzer. Five hundred one diabetes patients with experience in self-monitoring of BG were randomized to use three of five different BGM devices (FreeStyle Lite® [Abbott Diabetes Care Inc., Alameda, CA], FreeStyle Freedom Lite [Abbott Diabetes Care], OneTouch® UltraEasy® [LifeScan Inc., Milpitas, CA], Accu-Chek® Aviva [Roche Diagnostics, Mannheim, Germany], and Contour® [Bayer Vital GmbH, Leverkusen, Germany]) in a daily routine setting. All devices and strips were purchased from local regular distribution sources (pharmacies, four strip lots per device). The patients performed the finger prick and the glucose measurement on their own. In parallel, a healthcare professional performed the glucose assessment with the reference method (YSI 2300 Stat Plus). The primary objective was the comparison of the mean absolute relative differences (MARD). Secondary objectives were compliance with the International Organization for Standardization (ISO) accuracy criteria under these routine conditions and Clarke and Parkes Error Grid analyses. MARD ranged from 4.9% (FreeStyle Lite) to 9.7% (OneTouch UltraEasy). The ISO 15197:2003 requirements were fulfilled by the FreeStyle Lite (98.8%), FreeStyle Freedom Lite (97.5%), and Accu-Chek Aviva (97.0%), but not by the Contour (92.4%) and OneTouch UltraEasy (91.1%). The number of values in Zone A of the Clarke Error Grid analysis was highest for the FreeStyle Lite (98.8%) and lowest for the OneTouch Ultra Easy (90.4%). FreeStyle Lite, FreeStyle Freedom Lite, and Accu-Chek Aviva performed very well in this study with devices and strips purchased through regular distribution channels, with the FreeStyle Lite achieving the lowest MARD in this investigation.

The development of charged particle bombardment experiments to simulate neutron irradiation induced swelling in austenitic alloys is briefly described. The applications of these techniques in LMFBR core materials technology are discussed. It is shown that use of the techniques to study the behavior of cold-worked Type-316 was instrumental in demonstrating at an early date the need for advanced materials. The simulation techniques then were used to identify alloying elements which can markedly decrease swelling and thus a focused reactor irradiation program is now in place to allow the future use of a lower swelling alloy for LMFBR core components

2002-01-01
DIAMO, state owned enterprise, has a wide experience in uranium mining with the use of classical deep mining, acid in situ leaching and uranium ore processing. The sandstone deposits in Straz block have been exploited since 1968. Geological and hydrogeological conditions of the deposits and the short distance between the deep mine and ISL wellfields requires pumping huge amounts of fresh and/or acid mine water, their treatment and subsequent discharge into streams. DIAMO developed and applied several technologies for different types of wastewater treatment from the start of mining. Practically all of these technologies are used in the current phase of uranium deposit restoration after mining. It is possible to apply these technologies both in the production phase and during the restoration of underground water. In some cases, it is very desirable to combine two or several of them.

Compensated isocurvature perturbations (CIP), where the primordial baryon and cold dark matter density perturbations cancel, do not cause total matter isocurvature perturbation. Consequently, at the linear order in the baryon density contrast Δ, a mixture of CIP and the adiabatic mode leads to the same CMB spectra as the pure adiabatic mode. Only recently, Muñoz et al. showed that at the second order CIP leaves an imprint in the observable CMB by smoothing the power spectra in a similar manner as lensing. This causes a strong degeneracy between the CIP variance Δ{sub rms}{sup 2} ≡ (Δ{sup 2}) and the phenomenological lensing parameter A {sub L}. We study several combinations of the Planck 2015 data and show that the measured lensing potential power spectrum C {sub ℓ}{sup φφ} breaks the degeneracy. Nested sampling of the ΛCDM+Δ{sub rms}{sup 2}(+ A {sub L}) model using the Planck 2015 temperature, polarization, and lensing data gives Δ{sub rms}{sup 2} = (6.9{sup +3.0}{sub −3.1}) × 10{sup −3} at 68% CL. A non-zero value is favoured at 2.3σ (or without the polarization data at 2.8σ). CIP with Δ{sub rms}{sup 2} ≈ 7 × 10{sup −3} improves the bestfit χ{sup 2} by 3.6 compared to the adiabatic ΛCDM model. In contrast, although the temperature data favour A {sub L} ≅ 1.22, allowing A {sub L} ≠ 1 does not improve the joint fit at all, since the lensing data disfavour A {sub L} ≠ 1. Indeed, CIP provides a rare example of a simple model, which is capable of reducing the Planck lensing anomaly significantly and fitting well simultaneously the high (and low) multipole temperature and lensing data, as well as the polarization data. Finally, we derive forecasts for two future satellite missions (LiteBIRD proposal to JAXA/NASA and Exploring Cosmic Origins with CORE proposal to ESA's M5 call) and compare these to simulated Planck data. Due to its coarse angular resolution, LiteBIRD is not able to improve the constraints on Δ{sub rms}{sup 2} or A

Grid computing has been an increasing topic in recent years. It attracts the attention of many scientists from many fields. As a result, many Grid systems have been built for serving people's demands. At present, many tools for developing the Grid systems such as Globus, gLite, Unicore still developed incessantly. Especially, gLite - the Grid Middleware - was developed by the Europe Community scientific in recent years. Constant growth of Grid technology opened the way for new opportunities in term of information and data exchange in a secure and collaborative context. These new opportunities can be exploited to offer physicians new telemedicine services in order to improve their collaborative capacities. Our platform gives physicians an easy method to use telemedicine environment to manage and share patient's information (such as electronic medical record, images formatted DICOM) between remote locations. This paper presents the Grid Infrastructure based on gLite; some main components of gLite; the challenge scenario in which new applications can be developed to improve collaborative work between scientists; the process of deploying Hospital Open software Platform for E-health (HOPE) on the Grid.

Electron beam flue gas treatment technology is one of the most advanced technologies among new generation air pollution control processes. It is the only one process for simultaneous removal of SO 2 and NO x , applied in the industrial scale. Moreover other pollutants as acidic compounds, VOC and dioxins can be removed in one step. Among the other advantages a fully usable by-product – a fertilizer is created in the process. The industrial demonstrational plant was constructed in EPS Pomorzany in Szczecin (Poland). The facility treats the flue gases of maximum flow of 270.000 Nm 3 /h, which are irradiated by four accelerators of 700 keV electron energy and 260 kW beam power each. The removal efficiency of SO 2 in this installation may reach 95%, while removal efficiency of NO x – 70%. Apart of technical analysis also economical calculations of investment and operational costs of EBFGT installations, based on the data obtained on the Polish installation, was performed. The results show that in the case of multi-pollutant control the electron beam technology is strongly competitive to conventional technologies. Description of the experiences obtained during the operation of the plant and further possibilities of the technology development are presented in this paper. (author)

The Laser Astrometric Test of Relativity (LATOR) is a Michelson-Morley-type experiment designed to test the Einstein's general theory of relativity in the most intense gravitational environment available in the solar system - the close proximity to the Sun. By using independent time-series of highly accurate measurements of the Shapiro time-delay (laser ranging accurate to 1 cm) and interferometric astrometry (accurate to 0.1 picoradian), LATOR will measure gravitational deflection of light by the solar gravity with accuracy of 1 part in a billion, a factor {30,000 better than currently available. LATOR will perform series of highly-accurate tests of gravitation and cosmology in its search for cosmological remnants of scalar field in the solar system. We present science, technology and mission design for the LATOR mission.

Full Text Available Education in hydrology is changing rapidly due to diversification of students, emergent major scientific and practical challenges that our discipline must engage with, shifting pedagogic ideas and higher education environments, the need for students to develop new discipline specific and transferrable skills, and the advent of innovative technologies for learning and teaching. This paper focuses on new technologies in the context of learning and teaching in Physical Geography and reflects on the implications of our experiences for education in hydrology. We evaluate the experience of designing and trialling novel mobile technology-based field exercises and a virtual field tour for a Year 1 undergraduate Physical Geography module at a UK university. The new exercises are based on using and obtaining spatial data, operation of meteorological equipment (explained using an interactive DVD, and include introductions to global positioning systems (GPS and geographical information systems (GIS. The technology and exercises were well received in a pilot study and subsequent rolling-out to the full student cohort (∼150 students. A statistically significant improvement in marks was observed following the redesign. Although the students enjoyed using mobile technology, the increased interactivity and opportunity for peer learning were considered to be the primary benefits by students. This is reinforced further by student preference for the new interactive virtual field tour over the previous "show-and-tell" field exercise. Despite the new exercises having many advantages, exercise development was not trivial due to the high start-up costs, the need for provision of sufficient technical support and the relative difficulty of making year-to-year changes (to the virtual field tour in particular. Our experiences are highly relevant to the implementation of novel learning and teaching technologies in hydrology education.

New MMIS (Man Machine Interface System) technology is rapidly advanced as digital technology provides opportunity for more functionality and better cost effectiveness. Also, NPP (Nuclear Power Plant) operators are inclined to use the new technology for the construction of new plant and for the upgrade of existing plants. However, this new technology may include risks at the same time. These risks are mainly due to the poor reliability of newly developed technology. According to the user requirement (KURD: Korean Utility Requirement Document), advanced MMIS technology may be applied if it could be apparently needed to obtain a defined gain in simplicity or performance. For applying new MMIS technology, reliability needs to be verified on the basis of the requirements of proven technology. KURD suggests two methods for verifying satisfaction of the requirement of proven technology. These methods are to verity whether or not unproven MMIS technology has adequate reliability. First method is that it has at least three years of documented, satisfactory service as modules of subsystems in power plant applications similar to that in LWRs or in other than power plant applications which are similar to the use in the APR1400 M-MIS. Second method is that it has satisfactorily completed a defined program of prototype testing which has been designed to verify its performance in the APR1400 M-MIS application. But, new MMIS technology had not yet opportunity to apply in the Nuclear Power Plant. Therefore, we think that second method is the effective method to demonstrate reliability and performance of new technology through the experience accumulation test. In here, Experience accumulation test means that we emulate the process of nuclear power plant such as installation after shipping, trial operation, operation, and maintenance with MMIS facility and verify reliability and performance through various test method under the circumstance of emulation and if any problem occurs

Advanced Concepts, Technologies and Flight Experiments for NASA's Earth Science Enterprise
Meredith, Barry D.
2000-01-01
Over the last 25 years, NASA Langley Research Center (LaRC) has established a tradition of excellence in scientific research and leading-edge system developments, which have contributed to improved scientific understanding of our Earth system. Specifically, LaRC advances knowledge of atmospheric processes to enable proactive climate prediction and, in that role, develops first-of-a-kind atmospheric sensing capabilities that permit a variety of new measurements to be made within a constrained enterprise budget. These advances are enabled by the timely development and infusion of new, state-of-the-art (SOA), active and passive instrument and sensor technologies. In addition, LaRC's center-of-excellence in structures and materials is being applied to the technological challenges of reducing measurement system size, mass, and cost through the development and use of space-durable materials; lightweight, multi-functional structures; and large deployable/inflatable structures. NASA Langley is engaged in advancing these technologies across the full range of readiness levels from concept, to components, to prototypes, to flight experiments, and on to actual science mission infusion. The purpose of this paper is to describe current activities and capabilities, recent achievements, and future plans of the integrated science, engineering, and technology team at Langley Research Center who are working to enable the future of NASA's Earth Science Enterprise.

Preventing dangerous global climate change requires timely deployment of nascent energy technologies with zero or low Co2 emissions. Managing the shift to a common sustainable technology path calls for insight about the influence of global technological change on the national energy system. Moreover, national policies are required to promote the shift to the new technology path. This calls for methods to analyse the national energy system within a global perspective. The objective of the work presented in this thesis was to investigate interplay between technology diffusion, niche markets and technology learning from the perspective of a small open economy like Norway. More specifically, develop methods to include the influence of technology learning manifested in experience and learning curves into national energy-economy-environment models. Moreover, apply the methods to investigate the potential influence and sensitivity to technology learning in a small open economy. In this thesis three such methods have been developed, applied and its importance assessed using Norway as an example. In this work three models have been linked. They are the global Energy Technology Perspectives model operated by the International Energy Agency, the Norwegian Markal model at the Institute for Energy Technology and the macro economic model MSG6 at Statistics Norway. Method one and two has been developed to manage the interplay between the models. In a local perspective technology learning in the global market is perceived as spillover. Based upon a review of the characteristics of technological change and learning curves and its application to energy system modelling some criteria important for the parameterization and modelling of spillover in a small open economy are suggested. The first method incorporates spillover into the national Markal model. The second method establishes a soft-link between the national models. The soft-link served two purposes; to provide input on demand

Increasing awareness on environmental damage and climate change has induced many nations to engage in green growth. South Korea, as one of the largest consumers of energy, is no exception and has shown its determination to pursue green growth in the future. In order to do so, South Korea plans to substitute fossil fuel with alternative sources in electricity generation. However, the key constraint to green growth is the high cost faced by renewable electricity generation. Fortunately, nuclear energy can serve as an economic alternative to fossil fuel. To achieve CO 2 emission reduction and faster economic growth, it is wise to analyze prospects of alternatives using experience curve framework. The results and industry background are consistent for nuclear technology, and the results suggest that nuclear should serve as the main substitute. Consideration of policy risk inherent in renewable also strengthens the argument. Renewable technologies, on the other hand, showed overstated learning capacity that is partially inconsistent with technological background. Nevertheless, the renewable (photovoltaic and fuel cell) should help nuclear marginally in substituting fossil fuel in South Korea's Electricity Generation. - Highlights: ► Progress ratios of renewable energy show great prospect. ► The policy risk is inherent in renewable and may overestimate its prospect. ► Nuclear sources are economic and less affected by policy risk. ► Fuel cell and photovoltaic should help nuclear marginally in green growth.

1994-01-01
This paper describes the outstanding performance of the indigenous development program of nuclear power technology such as the design and fabrication of both CANDU and PWR fuel and in the design and construction of nuclear steam supply system in Korea. The success has been accomplished through the successful technology transfer from foreign suppliers and efficient utilization of R and D manpower in the design and engineering of nuclear power projects. In order to implement the technology transfer successfully, the joint design concept has been introduced along with effective on-the-job training and the transfer of design documents and computer codes. Korea's successful development of nuclear power program has resulted in rapid expansion of nuclear power generation capacity in a short time, and the nuclear power has contributed to the national economy through lowering electricity price by about 50 % as well as stabilizing electricity supply in 1980s. The nuclear power is expected to play a key role in the future electricity supply in Korea. Now Korea is under way of taking a step toward advanced nuclear technology. The national electricity system expansion plan includes 18 more units of NPPs to be constructed by the year 2006. In this circumstance, the country has fixed the national long-term nuclear R and D program (lgg2-2001) to enhance the national capability of nuclear technology. This paper also briefly describes future prospects of nuclear technology development program in Korea

Full Text Available It is substantiated that, taking into account the world trends in the development of fuel and energy complexes, in the near future the most preferable direction in using solid fossil fuels will become not just their burning but advanced thermochemical processing, which will result in obtaining such end products as substitutes for natural gas, electricity, and synthetic analogues of hydrocarbons. There analyzed foreign experience on commercialization of indirect coal gasification technologies, among which the technologies of traditional and plasma gasification are singled out. The advantages and disadvantages of these technologies are systematized, and the hypothesis about better prospects for using the technology of plasma gasification of coal in comparison with the traditional analogues that are based on the Fischer-Tropsch process is put forward.

Pre-service physics teacher skill in designing simple experiment set is very important in adding understanding of student concept and practicing scientific skill in laboratory. This study describes the skills of physics students in designing simple experiments based technologicall. The experimental design stages include simple tool design and sensor modification. The research method used is descriptive method with the number of research samples 25 students and 5 variations of simple physics experimental design. Based on the results of interviews and observations obtained the results of pre-service physics teacher skill analysis in designing simple experimental physics charged technology is good. Based on observation result, pre-service physics teacher skill in designing simple experiment is good while modification and sensor application are still not good. This suggests that pre-service physics teacher still need a lot of practice and do experiments in designing physics experiments using sensor modifications. Based on the interview result, it is found that students have high enough motivation to perform laboratory activities actively and students have high curiosity to be skilled at making simple practicum tool for physics experiment.

Hands-On Open Access Broadband Wireless Technology Lab Mapping Course Outcomes to Lab Experiments
Directory of Open Access Journals (Sweden)
Yazan Alqudah
2012-10-01
Full Text Available The unprecedented growth in wireless communication is offering opportunities and challenges for educators. Thanks to technology advances and job opportunities, more and more students are interested in wireless communications courses. However, bridging the gap between classroom and real-world experience remains a challenge. Advanced undergraduate communications courses typically focus more on theory. Some courses are given online, and lack hands-on experiments. Driven by feedback from industry and students, we propose practical laboratory experiments that attempt to bridge the gap between classroom and real world. The laboratory exercises take advantage of the infrastructure of deployed wireless networks and allow students to measure, and analyze data, as well as to interact. The proposed labs can be used even in online courses. This paper describes the experiments proposed, the procedures and typical results. The experiments are tied to course objective.

We introduce a simple model representing the underlying trade-off - between investing enough effort in any one project to spur rapid progress, and diversifying effort over many projects simultaneously to hedge against failure. We use stochastic experience curves to model the idea that investing more in a technology reduces its unit costs, and we use a mean-variance objective function to unders...

Full Text Available En este trabajo se investigaron las relaciones genéticas entre 17 poblaciones nativas sudamericanas en relación a 15 microsatélites (STRs autosómicos, utilizando 3 distancias genéticas- DST, DAy (δu2-que se ajustan a diferentes postulados teóricos. A través de diferentes técnicas de análisis (escalamiento multidimensional, correlación y correlación parcial de matrices se puso a prueba si las distancias genéticas reflejaban las relaciones interpoblacionales esperadas a partir de la distribución geográfica o de relaciones lingüísticas entre las poblaciones. Además, se estimó en que grado las distintas medidas de distancias genéticas eran influenciadas por la diversidad (He de cada población. Los mapas genéticos muestran, principalmente para DST y DA, que las poblaciones aisladas y con bajo tamaño efectivo (Ne aparecen como outliers, mientras que las poblaciones con alto Ne y mayor flujo génico ocupan una posición central a bajos valores de distancia unas de otras y sin un patrón definido de agrupamiento. La falta de asociación entre distancias genéticas y lingüísticas o geográficas y por otra parte, la alta correlación negativa entre He y distancias génicas promedio por población confiman ese patrón, demostrando que la mayor parte de la variación interpoblacional puede ser explicada en función del grado de diversidad intrapoblacional. Es decir, las distancias genéticas no reflejan relaciones filogenéticas, lingüísticas o geográficas, sino más bien eventos demográficos recientes tales como cuellos de botella genético, efecto fundador o migración externa masiva. Este hecho puede ser comprobado por medio de otra metodología analítica, el modelo de Harpending y Ward.

Full Text Available Los hallazgos arqueológicos en la costa norte peruana durante las últimas décadas han permitido constatar que el género femenino tuvo un peso muy importante en las estructuras regionales de poder. Se ha descubierto que las mujeres ocuparon cargos especiales en el mundo político-religioso, lo cual significa una importante contribución al actual análisis de la sociedad prehispánica en la costa norte del Perú. Este artículo analiza cuatro de estos cargos ocupados por mujeres de élite y argumenta que, posiblemente, tengan una vinculación directa entre ellos mediante un fuerte sentido de espiritualidad donde los mundos político, religioso y social aparecen fuertemente vinculados. Archaeological findings on the Northern coast of Peru in recent decades, have allowed for bringing to light the important role played by women in the power structures in the coast. The acknowledgement that women occupied special positions in the political and religious worlds, means a significant contribution to the current analysis of pre-Hispanic society in the Northern coast of Peru. Therefore, this article looks at four of these positions occupied by elite women, and argues that they may be intertwined by means of a strong sense of spirituality in which the political, the religious and the social worlds can't be dissociated from one another.

Multiple Payload Ejector for Education, Science and Technology Experiments
Lechworth, Gary
2005-01-01
The education research community no longer has a means of being manifested on Space Shuttle flights, and small orbital payload carriers must be flown as secondary payloads on ELV flights, as their launch schedule, secondary payload volume and mass permits. This has resulted in a backlog of small payloads, schedule and cost problems, and an inability for the small payloads community to achieve routine, low-cost access to orbit. This paper will discuss Goddard's Wallops Flight Facility funded effort to leverage its core competencies in small payloads, sounding rockets, balloons and range services to develop a low cost, multiple payload ejector (MPE) carrier for orbital experiments. The goal of the MPE is to provide a low-cost carrier intended primarily for educational flight research experiments. MPE can also be used by academia and industry for science, technology development and Exploration experiments. The MPE carrier will take advantage of the DARPAI NASA partnership to perform flight testing of DARPA s Falcon small, demonstration launch vehicle. The Falcon is similar to MPE fiom the standpoint of focusing on a low-cost, responsive system. Therefore, MPE and Falcon complement each other for the desired long-term goal of providing the small payloads community with a low-cost ride to orbit. The readiness dates of Falcon and MPE are complementary, also. MPE is being developed and readied for flight within 18 months by a small design team. Currently, MPE is preparing for Critical Design Review in fall 2005, payloads are being manifested on the first mission, and the carrier will be ready for flight on the first Falcon demonstration flight in summer, 2006. The MPE and attached experiments can weigh up to 900 lb. to be compatible with Falcon demonstration vehicle lift capabilities fiom Wallops, and will be delivered to the Falcon demonstration orbit - 100 nautical mile circular altitude.

This paper presents the results of using a stylized optimization model of the global electricity supply system to analyze the optimal research and development (R and D) support for an energy technology. The model takes into account the dynamics of technological progress as described by a so-called two-factor learning curve (2FLC). The two factors are cumulative experience ('learning by doing') and accumulated knowledge ('learning by searching'); the formulation is a straightforward expansion of conventional one-factor learning curves, in which only cumulative experience is included as a factor, which aggregates the effects of accumulated knowledge and cumulative experience, among others. The responsiveness of technological progress to the two factors is quantified using learning parameters, which are estimated using empirical data. Sensitivities of the model results to the parameters are also tested. The model results also address the effect of competition between technologies and of CO 2 constraints. The results are mainly methodological; one of the most interesting is that, at least up to a point, competition between technologies - in terms of both market share and R and D support - need not lead to 'lock-in' or 'crowding-out'

Recent NEA work on plutonium has been, essentially, targeted at economic and scientific aspects and the need to identify suitable technical solutions, despite the existing political uncertainties associated with their implementation. Such studies provide the facts and current views concerning plutonium and its civil use; address questions influencing the choice of fuel cycle options and illustrate how economic and logistic assessments of the alternatives could be undertaken. An ad-hoc expert group, with a membership drawn from fifteen countries and three international organisations, which was formed in early 1994 under the auspices of the NEA, with the task of identifying, examining and evaluating the broad technical questions related to plutonium management, has just published its work. This paper discusses the work and main conclusions of the expert group and focuses on the following two topics: Technologies, already implemented, which provide for short and medium-term storage of plutonium or for recycling the plutonium through reactors. A brief review is provided of experience gained with them and technical commentaries are made on their potential future deployment; Such technologies may, in the longer term, be joined by a further range which are, in some cases, already under development. Attention is drawn to those additional options that may become available. Another NEA expert group studied in detail the economics of the open and closed fuel cycles and reported, in 1994, its main findings: Some economic considerations of importance to various aspects of plutonium recycling are also presented in this paper.

We survey radiative Green function theory (1) in linear transport theory where numerical procedures are required to obtain specific results and (2) in the photon diffusion limit (large optical depths) where it is analytically tractable, at least for homogeneous plane-parallel media. We then describe two recent applications of Green function theory to passive cloud remote sensing in the presence of strong three-dimensional transport effects. Finally, we describe recent instrumental breakthroughs in 'off-beam' cloud lidar which is based on direct measurements of radiative Green functions with special attention to the data collected during the Shuttle-based Lidar In-space Technology Experiment (LITE) mission.

Full Text Available A variedade Goethe é símbolo da vitivinicultura da região de Urussanga, sul do Estado de Santa Catarina, a qual, atualmente, busca a Indicação Geográfica da Uva e do Vinho Goethe. Para isto, um dos requisitos necessários é a identificação precisa do material genético. Os marcadores microssatélites constituem a ferramenta molecular mais utilizada para a identificação varietal de videira em todo o mundo e têm a capacidade de produzir um perfil genético único para cada material vitícola. O objetivo deste trabalho foi caracterizar duas seleções de uva 'Goethe', presentes no município de Urussanga, por meio de marcadores moleculares microssatélites, visando a atender aos requisitos de denominação de origem e indicação de procedência controlada. A extração do DNA genômico foi realizada a partir de folhas jovens e ramos de nove acessos de cada seleção de 'Goethe Classica' e 'Goethe Primo' provenientes de uma coleção pública e de oito coleções privadas da região de Urussanga. Dez loci microssatélites VVS2, VVMD5, VVMD7, VVMD27, VrZAG62, VrZAG79, VVMD25, VVMD28, VVMD31 e VVMD32 foram genotipados através de eletroforese capilar. As análises realizadas mostraram que as duas variantes da uva 'Goethe' apresentaram um perfil molecular idêntico e único, isto é, representam a mesma variedade e sem nenhuma correspondência com variedades descritas anteriormente na literatura e nos bancos de dados consultados. As diferenças fenotípicas observadas provavelmente são devidas a mutações somáticas em regiões funcionais do genoma, fenômeno que dá origem aos clones em videira.'Goethe' grape is a symbol of the viticulture of Urussanga region, South of Santa Catarina State, which is currently claiming the geographical indication of the grape and wine Goethe.

The testing of new technologies aboard the International Space Station (ISS) is facilitated through the use of a passive experiment container, or PEC, developed at the NASA Langley Research Center. The PEC is an aluminum suitcase approximately 2 ft square and 5 in. thick. Inside the PEC are mounted Materials International Space Station Experiment (MISSE) plates that contain the test articles. The PEC is carried to the ISS aboard the space shuttle or a Russian resupply vehicle, where astronauts attach it to a handrail on the outer surface of the ISS and deploy the PEC, which is to say the suitcase is opened 180 deg. Typically, the PEC is left in this position for approximately 1 year, at which point astronauts close the PEC and it is returned to Earth. In the past, the PECs have contained passive experiments, principally designed to characterize the durability of materials subjected to the ultraviolet radiation and atomic oxygen present at the ISS orbit. The MISSE5 experiment is intended to characterize state-of-art (SOA) and beyond photovoltaic technologies.

Full Text Available This article aimed to answer how the use of computers and the Internet, directly and indirectly, has affected the time of teaching work and how these tool have determined the experience of teachers. Sources of research consisted of doctoral and master theses, as well as official documents that referring to these concepts and instruments. The survey instrument was developed as a form, using a software for the collection and analysis of data; for the assessment of the results we used the content analysis technique. The results show the relationship between time and experience under different cultural conventions that permeate the school, consolidating awareness under contradictions supported by the potential of new technologies in a condition of atrophying the experience to which the training process and the work of the teacher would tend to be reduced. The method is achieved from critical theory, especially the concepts of experience indicated by Adorno and Benjamin, ideology of technological rationality and industrial society, by Marcuse, and key concepts of dialectical materialism, such as alienated labor, commodity and machinery, from Marx.

Many technological and methodical advances have made stereotactic body radiotherapy (SBRT) more accurate and more efficient during the last years. This study aims to investigate whether experience in SBRT and technological innovations also translated into improved local control (LC) and overall survival (OS). A database of 700 patients treated with SBRT for lung metastases in 20 German centers between 1997 and 2014 was used for analysis. It was the aim of this study to investigate the impact of fluorodeoxyglucose positron-emission tomography (FDG-PET) staging, biopsy confirmation, image guidance, immobilization, and dose calculation algorithm, as well as the influence of SBRT experience, on LC and OS. Median follow-up time was 14.3 months (range, 0-131.9 months), with 2-year LC and OS of 81.2% (95% confidence interval [CI] 75.8%-85.7%) and 54.4% (95% CI 50.2%-59.0%), respectively. In multivariate analysis, all treatment technologies except FDG-PET staging did not significantly influence outcome. Patients who received pre-SBRT FDG-PET staging showed superior 1- and 2-year OS of 82.7% (95% CI 77.4%-88.6%) and 64.8% (95% CI 57.5%-73.3%), compared with patients without FDG-PET staging resulting in 1- and 2-year OS rates of 72.8% (95% CI 67.4%-78.8%) and 52.6% (95% CI 46.0%-60.4%), respectively (P=.012). Experience with SBRT was identified as the main prognostic factor for LC: institutions with higher SBRT experience (patients treated with SBRT within the last 2 years of the inclusion period) showed superior LC compared with less-experienced centers (P≤.001). Experience with SBRT within the last 2 years was independent from known prognostic factors for LC. Investigated technological and methodical advancements other than FDG-PET staging before SBRT did not significantly improve outcome in SBRT for pulmonary metastases. In contrast, LC was superior with increasing SBRT experience of the individual center. Copyright © 2016 Elsevier Inc. All rights reserved.

Background: When presenting to an imaging department, the person who is to be imaged is often in a vulnerable state, and can experience the scan in a number of ways. It is the role of the radiographer to produce a high quality image and facilitate patient care throughout the imaging process. A qualitative systematic review was performed to synthesise the existent evidence on the patient experience of high technology medical imaging. Only papers relating to Magnetic Resonance Imaging (MRI) and Computed Tomography (CT) were identified. Inclusion criteria: Studies that were of a qualitative design that explored the phenomenon of interest, the patient experience of high technology medical imaging. Participants included anyone who had undergone one of these procedures. Methods: A systematic search of medical and allied health databases was conducted. Articles identified during the search process that met the inclusion criteria were then critically appraised for methodological quality independently by two reviewers. Results: During the search and inclusion process, 15 studies were found that were deemed of suitable quality to be included in the review. From the 15 studies, 127 findings were extracted from the included studies. These were analysed in more detail to observe common themes, and then grouped into 33 categories. From these 33 categories, 11 synthesised findings were produced. The 11 synthesised findings highlight the diverse, unique and challenging ways in which people experience imaging with MRI and CT scanners. Conclusion: The results of the review demonstrate the diverse ways in which people experience medical imaging. All health professionals involved in imaging need to be aware of the different ways each patient may experience imaging.

Recent attempts by large tobacco companies to represent themselves as socially responsible have been widely dismissed as image management. Existing research supports such claims by pointing to the failings and misleading nature of corporate social responsibility (CSR) initiatives. However, few studies have focused in depth on what tobacco companies hoped to achieve through CSR or reflected on the extent to which these ambitions have been realised. Iterative searching relating to CSR strategies was undertaken of internal British American Tobacco (BAT) documents, released through litigation in the US. Relevant documents (764) were indexed and qualitatively analysed. In the past decade, BAT has actively developed a wide-ranging CSR programme. Company documents indicate that one of the key aims of this programme was to help the company secure access to policymakers and, thereby, increase the company's chances of influencing policy decisions. Taking the UK as a case study, this paper demonstrates the way in which CSR can be used to renew and maintain dialogue with policymakers, even in ostensibly unreceptive political contexts. In practice, the impact of this political use of CSR is likely to be context specific; depending on factors such as policy élites' understanding of the credibility of companies as a reliable source of information. The findings suggest that tobacco company CSR strategies can enable access to and dialogue with policymakers and provide opportunities for issue definition. CSR should therefore be seen as a form of corporate political activity. This underlines the need for broad implementation of Article 5.3 of the Framework Convention on Tobacco Control. Measures are needed to ensure transparency of interactions between all parts of government and the tobacco industry and for policy makers to be made more aware of what companies hope to achieve through CSR.

Infrared multilayer interface filter which were used in satellite radiometers were examined. The ability of the filters to withstand the space environment in these applications is critical. An experiment on the LDEF subjects the filters to authoritative spectral measurements following space exposure to ascertain their suitability for spacecraft use and to permit an understanding of degradation mechanisms. The understanding of the effects of prolonged space exposure on spacecraft materials, surface finishes, and adhesive systems is important to the spacecraft designer. Materials technology experiments and experiment on infrared multilayer filters are discussed.

Commercialization of Plasma-Assisted Technologies: The Indian Experience
John, P. I.
The paper describes an initiative by the Institute for Plasma Research (IPR), India in establishing links with the Indian industry for developing and commercialising advanced plasma-based industrial technologies. This has culminated in the creation of a self-financing technology development, incubation, demonstration and delivery facility. A business plan for converting the knowledge base to commercially viable technologies conceived technology as a product and the industry as the market and addressed issues like resistance to new technologies, the key role of entrepreneur, thrust areas and the necessity of technology incubation and delivery. Success of this strategy is discussed in a few case studies. We conclude by identifying the cost, environmental, strategic and techno-economic aspects, which would be the prime drivers for plasma-assisted manufacturing technology in India.

The objective of this research is to examine issues related to the increasing importance of energy-efficient technologies in high-rise construction. The aim of the paper is to investigate modern approaches to building design that involve implementation of various energy-saving technologies in diverse climates and at different structural levels, including the levels of urban development, functionality, planning, construction and engineering. The research methodology is based on the comprehensive analysis of the advanced global expertise in the design and construction of energy-efficient high-rise buildings, with the examination of their positive and negative features. The research also defines the basic principles of energy-efficient architecture. Besides, it draws parallels between the climate characteristics of countries that lead in the field of energy-efficient high-rise construction, on the one hand, and the climate in Russia, on the other, which makes it possible to use the vast experience of many countries, wholly or partially. The paper also gives an analytical review of the results arrived at by implementing energy efficiency principles into high-rise architecture. The study findings determine the impact of energy-efficient technologies on high-rise architecture and planning solutions. In conclusion, the research states that, apart from aesthetic and compositional interpretation of architectural forms, an architect nowadays has to address the task of finding a synthesis between technological and architectural solutions, which requires knowledge of advanced technologies. The study findings reveal that the implementation of modern energy-efficient technologies into high-rise construction is of immediate interest and is sure to bring long-term benefits.

AECL experience with low-level radioactive waste technologies
International Nuclear Information System (INIS)
Buckley, L.P.; Charlesworth, D.H.
1988-08-01
Atomic Energy of Canada Limited (AECL), as the Canadian government agency responsible for research and development of peaceful uses of nuclear energy, has had experience in handling a wide variety of radioactive wastes for over 40 years. Low-level radioactive waste (LLRW) is generated in Canada from nuclear fuel manufacturers and nuclear power facilities, from medical and industrial uses of radioisotopes and from research facilities. The technologies with which AECL has strength lie in the areas of processing, storage, disposal and safety assessment of LLRW. While compaction and incineration are the predominant methods practised for solid wastes, purification techniques and volume reduction methods are used for liquid wastes. The methods for processing continue to be developed to improve and increase the efficiency of operation and to accommodate the transition from storage of the waste to disposal. Site-specific studies and planning for a LLRW disposal repository to replace current storage facilities are well underway with in-service operation to begin in 1991. The waste will be disposed of in an intrusion-resistant underground structure designed to have a service life of over 500 years. Beyond this period of time the radioactivity in the waste will have decayed to innocuous levels. Safety assessments of LLRW disposal are performed with the aid of a series of interconnected mathematical models developed at Chalk River specifically to predict the movement of radionuclides through and away from the repository after its closure and the subsequent health effects of the released radionuclides on the public. The various technologies for dealing with radioactive wastes from their creation to disposal will be discussed. 14 refs

Grid enablement of OpenGeospatial Web Services: the G-OWS Working Group
Mazzetti, Paolo
2010-05-01
integration on existing solutions. More specifically, the Open Geospatial Consortium (OGC) Web Services (OWS) specifications play a fundamental role in geospatial information sharing (e.g. in INSPIRE Implementing Rules, GEOSS architecture, GMES Services, etc.). On the Grid side, the gLite middleware, developed in the European EGEE (Enabling Grids for E-sciencE) Projects, is widely spread in Europe and beyond, proving its high scalability and it is one of the middleware chosen for the future European Grid Infrastructure (EGI) initiative. Therefore the convergence between OWS and gLite technologies would be desirable for a seamless access to the Grid capabilities through OWS-compliant systems. Anyway, to achieve this harmonization there are some obstacles to overcome. Firstly, a semantics mismatch must be addressed: gLite handle low-level (e.g. close to the machine) concepts like "file", "data", "instruments", "job", etc., while geo-information services handle higher-level (closer to the human) concepts like "coverage", "observation", "measurement", "model", etc. Secondly, an architectural mismatch must be addressed: OWS implements a Web Service-Oriented-Architecture which is stateless, synchronous and with no embedded security (which is demanded to other specs), while gLite implements the Grid paradigm in an architecture which is stateful, asynchronous (even not fully event-based) and with strong embedded security (based on the VO paradigm). In recent years many initiatives and projects have worked out possible approaches for implementing Grid-enabled OWSs. Just to mention some: (i) in 2007 the OGC has signed a Memorandum of Understanding with the Open Grid Forum, "a community of users, developers, and vendors leading the global standardization effort for grid computing."; (ii) the OGC identified "WPS Profiles - Conflation; and Grid processing" as one of the tasks in the Geo Processing Workflow theme of the OWS Phase 6 (OWS-6); (iii) several national, European and

Interactive technologies provide various kinds of user interaction (sound, images, animations, etc. and is a basic tool for the creation of computer training programs. The synthesis of traditional and modern information technology is based on the activity- when learning activities are the subject of training and help to create an overview of the professional activities of an interpreter as a purposeful, active, long-term process of learning. Using an interdisciplinary approach makes it possible to seamlessly integrate the knowledge of linguistics and computer science, linguistics and psychology. The purpose of this paper is the analysis of experience in the use of new information technologies in the training of future translators in UK universities. In this research we identified the most common programs used in the preparation of translators, substantiated the possibility of their application, named the city and universities in the UK where such training is carried out.

Enabling kinetic micro-penetrator technology for Solar System research
Gowen, R. A.
2008-09-01
Whilst the concept of high speed impacting penetrator probes is not new, recent highly successful ground test results have considerably improved the perception that these can be a viable and useful addition to the current toolbox of planetary probes. Previous developments only led to a single deployment (Deep Space-2 to Mars on the ill fated NASA Mars Polar Lander mission in 1999) where neither the soft lander nor penetrator was ever heard from, which is not a logical basis for dismissing penetrator technology. Other space penetrator programmes have included the Russian Mars'96 ~80m/s penetrators for which the whole mission was lost before the spacecraft left Earth orbit, and the Japanese Lunar-A program which was cancelled after a lengthy development program which however saw multiple successful ground trials. The Japanese penetrators were designed for ~300m/s impact. The current UK penetrator developments are actively working towards full space qualification for a Lunar penetrators (MoonLITE mission), which would also provide a significant technical demonstration towards the development of smaller, shorter lived penetrators for exploring other solar system objects. We are advocating delivered micro-penetrators in the mass range ~4-10Kg, (preceded by ~13Kg Lunar penetrator MoonLITE development program), impacting at around 100-500m/s and carrying a scientific payload of around 2Kg. Additional mass is required to deliver the probes from `orbit' to surface which is dependent upon the particular planetary body in question. The mass per descent module therefore involves and additional element which, for a descent through an atmosphere could be quite modest, while for a flyby deployment, can be substantial. For Europa we estimate a descent module mass of ~13 Kg, while for Enceladus the value is ~40Kg for Enceladus since a deceleration of ~3.8 kms-1 is needed from a Titan orbit. The delivery system could consist of a rocket deceleration motor and attitude control system

The Synergy CircuLite micropump is a novel partial-support miniature left ventricular assist device that propels 2-3 l/min blood from the left atrium into the right subclavian artery. The ability of currently available investigative modalities to confirm Synergy pump malfunction is limited. The Synergy speed fluctuates periodically (at 10-s intervals) from the baseline to a transient decrease followed by a transient increase (alternating speed algorithm, ASA) with the purpose of changing the blood flow behaviour, thereby reducing thrombogenicity. The aim of this study was to develop a simple non-invasive monitoring technique to assess pump function based on the detection of the ASA in the peripheral microcirculation. Between February 2012 and July 2013, 10 patients with advanced chronic heart failure underwent Synergy implantation at our institution. The pump function was assessed by echocardiography and invasive monitoring according to standard protocols; additionally, the pump speed and power consumption were monitored. During the pump function assessment, the pulse oximeter waveform was recorded from the index fingers of the left and right hand with simultaneous pump auscultation using a stethoscope positioned on the pump (right infra-clavicular pocket). The pulse oximeter waveform was readily detectable from the right and left hand of all study patients. If the Synergy function was normal, there was a significant difference in the morphology of the pulse oximeter waveform from each hand: the ASA algorithm produced a more pronounced variation (giant wave) in the trace from the right hand than from the left. The giant waves invariably coincided with the sound variation associated with the ASA algorithms, which were detected regularly at 10-s intervals. We describe a simple, readily applicable, inexpensive, non-invasive technique that allows evaluation of Synergy pump function and may have diagnostic utility under conditions of suspected pump thrombus

Hard of hearing students usually face more difficulties at school than other students. A classroom environment with wireless technology was implemented to explore whether wireless technology could enhance mathematics learning and teaching activities for a hearing teacher and her 7 hard of hearing students in a Taiwan junior high school. Experiments showed that the highly interactive communication through the wireless network increased student participation in learning activities. Students demonstrated more responses to the teacher and fewer distraction behaviors. Fewer mistakes were made in in-class course work because Tablet PCs provided students scaffolds. Students stated that the environment with wireless technology was desirable and said that they hoped to continue using the environment to learn mathematics.

Non destructive testing (NDT) is an essential technology for quality control leading to more reliable and safer industrial as well as nuclear plants. This was the main reason for the IAEA to undertake the promotion of this technology in the world. Through its regional and technical assistance programmes the NDT technology programmes encompass approximately more than 80 developing countries. The main focus of the NDT programme has been the creation of core groups of personnel able to undertake education, training and certification of NDT personnel and provision of NDT services to industries, creation of national certifying bodies, issuance of national standards compatible with ISO 9712 and the establishment of Professional NDT Societies. The programme has met a great success in most of the Member States. The paper will review the programmes of the IAEA in the field of NDT and provide an assessment of the present status of NDT technology development both in the developing as well as developed countries.

Background The current popularity of mindfulness-based practices has coincided with the increase in access to mobile technology. This has led to many mindfulness apps and programs becoming available, some specifically for children. However, little is known about the experience of engaging with mindfulness through these mediums. Aims To explore children's experience of mindfulness delivered both face-to-face and through a computer game to highlight any differences or similarities. Method A two-armed qualitative focus groups design was used to explore children's experiences. The first arm offered mindfulness exercises in a traditional face-to-face setting with guided meditations. The second arm offered mindfulness exercises through a computer game avatar. Results Themes of relaxation, engagement, awareness, thinking, practice and directing attention emerged from both arms of focus groups. Subthematic codes highlight key differences as well as similarities in the experience of mindfulness. Conclusions These results indicate that mindfulness delivered via technology can offer a rich experience. © The Royal College of Psychiatrists 2017.

Most research on learning in the field of dementia has studied teaching approaches, while little is known about learning as experienced and enacted by the people with dementia. The aim was to explore the lived experience of learning and maintaining knowledge related to technology among people with mild to moderate stage dementia. Seven persons with dementia were interviewed in-depth, and data were analyzed with a phenomenological approach. The participants positioned themselves on a continuum from 'Updating and expanding is not for me' to 'Updating and expanding is really for me'. They used different ways of learning in their everyday life - relying on one's habituated repertoire of actions, on other people or on technology itself, or belonging to a learning context. We have much to gain from better understanding of how people with dementia strive to learn and maintain their skills and knowledge related to technology. This is particularly important as they seem to use other approaches than those employed in current teaching methods. The necessity of learning stands out particularly when it comes to the interaction with the current multitude and ever-changing designs of technologies, including assistive technologies developed specifically to support people with dementia.

Nuclear engineering experiments using outside facilities of the campus have been offered for graduate students in the nuclear engineering course in Tokyo Institute of Technology (Tokyo Tech.). The experiments are managed with the collaboration of Japan Nuclear Cycle Development Institute (JNC), Japan Atomic Energy Research Institute (JAERI) and Research Reactor Institute, Kyoto University (KUR). This report presents the new curriculum of the nuclear engineering experiments at JNC since 2002. The change is due to the shutdown of Deuterium Criticality Assembly Facility (DCA) that was used as an experimental facility until 2001. Reactor physics experiment using the training simulator of the experimental fast reactor JOYO is continued from the previous curriculum with the addition of the criticality approach experiment and control rods calibration. A new experimental subject is an irradiated material experiment at the Material Monitoring Facility (MMF). As a result, both are acceptable as the student experiments on the fast reactor. (author)

The technological achievements and experience at JET

1999-01-01
The Joint European Torus, JET, the largest and most successful Tokamak in the world, was conceived from the start as a research project with very ambitious aims and a bold approach to extrapolations of the physics and technology base as well as the international nature of its organisation. Throughout its operating life the JET team has maintained this approach and, with its innovative and flexible design, has extended its performance far beyond the initially intended boundaries thereby retaining a lead in virtually all areas of fusion research. The team has shown a willingness to venture far beyond the technology base of the time into new areas and dimensions. The paper will highlight a few examples which illustrate the approach taken in JET to work closely with industry and the European Associations to extend the technology beyond the current state of the art whilst maintaining a tight grip on the fundamental requirements of cost and time schedule. These range from large scale integrated systems as well as small scale technological breakthroughs. Large scale systems include the Active Gas Handling System for the on-line reprocessing of the tritium-deuterium fuel, the Remote Handling System which was integrated into the JET machine from the very beginning, the JET Power Supply system as well as, most importantly, the design of the JET structure itself which permitted the fast maintenance and repair of all major sub-units. Other notable advances include the Neutral Beam Injection and Radio Frequency Heating systems, the large open structure cryo-pumps and the novel cryo-transmission lines. Some of the associated technologies required major advances in the area of diagnostics, high power handling components, carbon fibre reinforced carbon materials as well as in the whole field of beryllium technology and beryllium handling.

This article analyzes nanotechnology as an experiment in democratic deliberation, one that seems motivated both by a desire to improve deliberative democracy and to protect the technology from undue public interference. However, rather than involving amplified (overstated) risks, nanotechnology appears to involve attenuated (understated) risks. Results from a 3-year panel study are presented to illustrate the ways in which citizens form opinions about nanotechnology, supporting the assertion that public opinion about complex technology can be both reasonable and stable. Nevertheless, the authors also voice concern that, in the absence of public pressure, risk regulation may not evolve as swiftly as it should to protect both society and industry.

Full Text Available This paper accounts for an innovative pedagogical experience carried out within the terms of the DINIECE, MECYT - FAHCE, UNLP agreement, which calls for the use of Geographical Information Systems (GIS with pedagogical purposes. Such experience took place in the course called "Urban Itineraries Seminar" at the Colegio Nacional Rafael Hernández, UNLP. From a geographical and didactic critical belief, the students were encouraged to understand the socio-environmental reality they live in. In order to do this, environmental issues were identified in the area of La Plata by means of a territorial and spatial analysis. The students lived and experienced a new line of work in which innovation was signated by the use of new technologies (GIS together with the didactic methodology which encourages meaningful learning.

To describe and explore parents' experiences when their children with severe physical impairments receive gaze-based assistive technology (gaze-based assistive technology (AT)) for use in daily life. Semi-structured interviews were conducted twice, with one year in between, with parents of eight children with cerebral palsy that used gaze-based AT in their daily activities. To understand the parents' experiences, hermeneutical interpretations were used during data analysis. The findings demonstrate that for parents, children's gaze-based AT usage meant that children demonstrated agency, provided them with opportunities to show personality and competencies, and gave children possibilities to develop. Overall, children's gaze-based AT provides hope for a better future for their children with severe physical impairments; a future in which the children can develop and gain influence in life. Gaze-based AT provides children with new opportunities to perform activities and take initiatives to communicate, giving parents hope about the children's future.

This paper is a report of a review to describe and discuss the psychometric properties of instruments used in healthcare education settings measuring experience and attitudes of healthcare students regarding their information and communication technology skills and their use of computers and the Internet for education. Healthcare professionals are expected to be computer and information literate at registration. A previous review of evaluative studies of computer-based learning suggests that methods of measuring learners' attitudes to computers and computer aided learning are problematic. A search of eight health and social science databases located 49 papers, the majority published between 1995 and January 2007, focusing on the experience and attitudes of students in the healthcare professions towards computers and e-learning. An integrative approach was adopted, with narrative description of findings. Criteria for inclusion were quantitative studies using survey tools with samples of healthcare students and concerning computer and information literacy skills, access to computers, experience with computers and use of computers and the Internet for education purposes. Since the 1980s a number of instruments have been developed, mostly in the United States of America, to measure attitudes to computers, anxiety about computer use, information and communication technology skills, satisfaction and more recently attitudes to the Internet and computers for education. The psychometric properties are poorly described. Advances in computers and technology mean that many earlier tools are no longer valid. Measures of the experience and attitudes of healthcare students to the increased use of e-learning require development in line with computer and technology advances.

Data-acquisition systems for high-energy physics experiments like the ATLAS experiment at the European particle-physics research institute CERN are used to record experimental physics data and are essential for the effective operation of an experiment. Located in underground facilities with limited space, power, cooling, and exposed to ionizing radiation and strong magnetic fields, data-acquisition systems have unique requirements and are challenging to design and build. Traditionally, these systems have been composed of custom-designed electronic components to be able to cope with the large data volumes that high-energy physics experiments generate and at the same time meet technological and environmental requirements. Custom-designed electronics is costly to develop,effortful to maintain and typically not very flexible. This thesis explores an alternative architecture for data-acquisition systems based on commercial off-the-shelf (COTS) components. A COTS-based data distribution device called FELIX that will be integrated in ATLAS is presented. The hardware and software implementation of this device is discussed, with a specific focus on performance, heterogenity of systems and traffic patterns. The COTS-based readout approach is evaluated in the context of the future requirements of the ATLAS experiment. The main contributions of the thesis are an analysis of the ATLAS data-acquisition system with a focus on the readout system, a software architecture for the main application on FELIX hosts, a performance analysis and tuning based on computer science methods for central FELIX software components with respect to the requirements of the ATLAS experiment, a network communication library with a high-level software interface to utilize high-performance computing network technology for the purpose of data-acquisition systems, and an evaluation and discussion of ATLAS data-acquisition using FELIX systems as a case study for COTS-based data-acquisition in high

Decontamination is one of the most important technologies for the decommissioning of NPP. The purpose of decontamination is to reduce the Risk of exposure of the decommissioning workers, and to recycle parts of the plant components. Currently, there is a lack of data on the efficiency of the decontamination technologies for decommissioning. In most cases, the local radiation level can be lowered below a regulatory limitation by decontamination. Therefore, more efficient decontamination technology must be continuously developed. This work describes the practical experiences in the United States and the European countries for NPP decommissioning using these decontamination technologies. When the decommissioning of domestic nuclear power plant is planned and implemented, this work will be helpful as a reference of previous cases.

Since 2003, Andra (the French public body in charge of radioactive waste management) has been working on the progressive technological development of waste storage containers, package handling mechanical prototypes, excavation techniques and support lining of underground openings at the Bure Underground Laboratory (URL) site, in order to evaluate the feasibility of constructing and operating a Deep Geological Repository (DGR aka Cigeo), in the Callovian-Oxfordian clayish formation (the ''Argillites''), likely to receive as of 2025-2030 the first of many intermediate and high-level long lived wastes, at a 500m depth. The Cigeo Project, which has now entered into an intense engineering development phase, must take into account all the data, knowledge and experience gathered over more than 10 years of technical research. The spectrum of activities concerned encompasses a wide array of subjects such as the return of experience gathered from the shaft sinking operations, the drift excavation operations (via means of rock hammer, road header and tunnel boring machine) and the subsequent lining support of the horizontal drifts (via metal arches, mesh, rock bolts, shotcrete, cast concrete and wedges). The story of coring, drilling and casing vertical, slanted or horizontal boreholes is also of interest. The implementation and evaluation of sealing technologies or hydraulic cut-offs must be integrated in the design. The construction and qualification in 3 campaigns of 9 families of concrete containers and 3 categories of carbon steel overpacks also come as input data. The design, construction and testing of 3 package emplacement systems, the implementation of 2 waste retrievability tests are accounted for in the studies ongoing. Finally the collation of environmental and geotechnical data on the excavated material (likely to be re- used for opening backfilling at time of repository closure) will help to minimize the acreage, volume and visual impact of

2018-01-01
Optimization experiment of SCR denitrification technologies on a 300MW unit was conducted. Adjustment of ammonia injection quantity of corresponding AIG was conducted after measuring the SCR export NOx concentration field in 250MW load, the distribution uniformity of NOx volume fraction at the outlet of both reactor A and B was improved significantly, where the relative standard deviation of NOx reduced respectively from 29.83% to 13.01% and 24.54% to 9.26%, simultaneously, the amount of ammonia escape of A, B reactor decrease respectively by 24.76%, 19.45%. The results of optimization experiment show that, optimal adjustment can improve the NOx concentration distribution, reduce the amount of ammonia escape in a certain extent, and judge whether the catalytic activity of the regional catalyzer is in good condition. As to the area where catalyst is ineffective, the effect of optimization experiment is limited, the catalyzer should be the timely replacement, so as to better protect downstream equipment.

O MIRAX (Monitor e Imageador de RAios-X) é um projeto de desenvolvimento de um pequeno satélite astronômico de raios-X (~200 kg, ~240 W). A estratégia básica da missão será observar continuamente (~9 meses por ano) a região central (~1000 graus2) do plano Galáctico e realizar estudos espectroscópicos de banda larga (2-200 keV) e alta sensibilidade de um grande conjunto de fontes através de imagens com resolução de ~6'. Isso proporcionará uma cobertura inédita do "espaço de descobertas" através da detecção, localização, identificação e estudo detalhado de fenômenos imprevisíveis, tais como transientes fracos de raios-X, novas rápidas de raios-X e bursts de raios gama, assim como o estudo de fontes com emissão persistente. Neste trabalho apresentamos o projeto das duas câmeras de raios-X duros (CXDs) do MIRAX, que irão operar na faixa de 10 a 200 keV. Cada CXD consistirá de um plano de detectores CZT (Cd0,9Zn0,1Te) de 0,5 mm de resolução espacial e 370 cm2 de área total, e de uma máscara codificada com elementos quadrados de 1,3 mm de lado e 0,5 cm de espessura. A máscara terá dimensões de 315 cm ´ 275 cm e será montada a 700 cm de distância dos detectores. Com essa configuração as CXDs terão 6' de resolução angular e, quando colocadas a um ângulo de 29° entre si, as duas câmeras propiciam um campo totalmente codificado de 39° ´ 6°12' e um campo total de 76° ´ 44°. Serão apresentadas simulações de observações da região do plano Galáctico com o conjunto formado pelas duas CXDs.

The approach to the reprocessing of irradiated fuel from power reactors in India is conditioned by the non-availability of highly enriched uranium with the consequent need for plutonium for the fast-reactor programme. With this in view, the fuel reprocessing programme in India is developing in stages matching the nuclear power programme. The first plant was set up in Trombay to reprocess the metallic uranium fuel from the research reactor CIRUS. The experience gained in the construction and operation of this plant, and in its subsequent decommissioning and reconstruction, has not only provided the know-how for the design of subsequent plants but has indicated the fruitful areas of research and development for efficient utilization of limited resources. The Trombay plant also handled successfully, on a pilot scale, the reprocessing of irradiated thorium fuel to separate uranium-233. The second plant at Tarapur has been built for reprocessing spent fuels from the power reactors at Tarapur (BWR) and Rajasthan (PHWR). The third plant, at present under design, will reprocess the spent fuels from the power reactors (PHWR) and the Fast Breeder Test Reactor (FBTR) located at Kalpakkam. Through the above approach experience has been acquired which will be useful in the design and construction of even larger plants which will become necessary in the future as the nuclear power programme grows. The strategies considered for the sizing and siting of reprocessing plants extend from the idea of small plants, located at nuclear power station sites, to a large-size central plant, located at an independent site, serving many stations. The paper discusses briefly the experience in reprocessing uranium and thorium fuels and also in decommissioning. An attempt is made to outline the technological and economic aspects which are relevant under different circumstances and which influence the size and siting of the fuel reprocessing plants and the expected lead times for construction

Full Text Available A technological divide exists in Zimbabwe between urban and rural schools that puts rural based students at a disadvantage. In Zimbabwe, the government, through the president donated computers to most rural schools in a bid to bridge the digital divide between rural and urban schools. The purpose of this phenomenological study was to understand the experiences of Advanced Level students using computers at two rural boarding Catholic High Schools in Zimbabwe. The study was guided by two research questions: (1 How do Advanced level students in the rural areas use computers at their school? and (2 What is the experience of using computers for Advanced Level students in the rural areas of Zimbabwe? By performing this study, it was possible to understand from the students’ experiences whether computer usage was for educational learning or not. The results of the phenomenological study showed that students’ experiences can be broadly classified into five themes, namely worthwhile (interesting experience, accessibility issues, teachers’ monopoly, research and social use, and Internet availability. The participants proposed teachers use computers, but not monopolize computer usage. The solution to the computer shortage may be solved by having donors and government help in the acquisitioning of more computers.

Grand multiparae's evolving experiences of birthing and technology in U.S. hospitals.
Fleming, Susan E; Vandermause, Roxanne
2011-01-01
To explore the nature of birthing in United States (U.S.) hospitals from 1973-2007 and to explicate and interpret common, often overlooked, birthing experiences and nursing care. A Heideggerian phenomenological approach utilizing in-depth interviews. Participants' homes in Washington, Idaho, and Oregon. A purposive sample of grand multiparaes (N = 14). Data were collected via open conversational interviews of 60-90 minutes recorded on digital media and completion of a demographic and birth attribute form. Field notes and interpretive commentary were used as additional data sources and were analyzed using an established Heideggerian approach. The participants came from diverse religious and ethical backgrounds and experienced 116 births (8.29 births per woman, 79% unmedicated), a Cesarean rate of 6%, and a breastfeeding rate of 99% with a mean duration of 12 months. Two overarching patterns emerged: pursuing the "'good birth": a safe passage for baby and being in-and-out of control: body, technology, others. Each pattern subsumed several overlapping themes. The first pattern revealed that women often desire a good birth in the safety of a hospital by navigating their options prior to and during the birth. The second pattern revealed a common, yet often unachievable, desire by all of those involved in the process to control birth. Harmonizing an exchange of ideas in a technologically advanced environment prevalent in hospitals today can increase the quality of intrapartum care. Encouraging anchored companions and promoting normal physiological birth will make hospitals places where women can experience a good birth and feel safe. © 2011 AWHONN, the Association of Women's Health, Obstetric and Neonatal Nurses.

Full Text Available The development and dissemination of sawah rice eco-technology in Nigeria and Ghana as prerequisites for the actualization of green revolution in West Africa were described. It showed that the neglect of the eco-technology and the overemphasis of the biotechnology have rendered the ineffective transferability of the green revolution process from Asia to Africa. The sawah eco-technology increases yield up to 5 t/hm2 through bunding and the use of inlet and outlet connecting irrigation and drainage, which enhances effective water control and management, improves the efficiency of fertilizer, improves nitrogen fixation by soil microbes and algae, increases the use of wetlands, improves soil organic matter accumulation, suppresses weed growth, and enhances immune mechanism of rice through nutrient supply. The current experience has therefore established that the technology overcomes the constraints that have limited the realization of green revolution in West Africa.

Full Text Available El objetivo de este artículo es explicar las reformas de las reglas de reelección que tuvieron lugar en 2015 en cuatro países latinoamericanos: República Dominicana, Honduras, Colombia y Brasil. Contrariamente a lo que sostiene la literatura comparada reciente, se argumenta que estas reformas se deben básicamente a motivaciones estratégicas y objetivos particularistas de las élites políticas que las promovieron. Tanto en el caso de las permisivas (República Dominicana y Honduras como las restrictivas (Colombia y Brasil, las reformas responden a intereses electorales de corto plazo de los actores políticos y están ausentes las razones de eficiencia del sistema y consensos amplios para la aprobación de los cambios de los sistemas electorales. En términos más generales, el artículo argumenta que un marco analítico para el estudio de las reformas electorales debería abarcar tres dimensiones: las motivaciones y objetivos de la coalición reformista, los propios actores que promueven la reforma y la manera de como esta se aprobó.

It is imperative to tackle the issue globally mobilizing all available policies and measures. One of the important ones among them is technology transfer and diffusion. By utilizing international co-operation, industry can promote such measures in two ways: through government policy and through industry's own voluntary initiative. Needless to say, various government policies and measures play essential role. By the same token, industry initiative can complement them. There is much literature documenting the former. On the contrary there are few on the latter. This paper sheds light on the latter. The purpose of this paper is to explore the effectiveness of global voluntary sectoral approach for technology diffusion and transfer based on steel sector experience. The goal is to contribute toward building a worldwide low-carbon society by manufacturing goods with less energy through international cooperation of each sector. The authors believe that the voluntary sectoral approach is an effective method with political and practical feasibilities, and hope to see the continued growth of more initiatives based on this approach. - Highlights: → There exist huge reduction potentials in steel industries globally. → Technology transfer and diffusion are keys to achieve reductions. → Main barriers are economic, technological and policy-related. → Case studies in overcoming barriers are discussed. → In steel industry, a voluntary sectoral approach has shown to be effective.

Nowadays public acceptance is the most frequent keyword used in the Brazilian nuclear scenario with the revival of the nuclear program, in which the construction of more nuclear power plants and a national radioactive waste repository are expected. The acceptance of such activities is tightly linked to a strategic communication plan, the effective tool to be implemented if success is intended. Isolated communication actions are being done in the nuclear area and this paper presents one example of them, describing the experience with college students from two educational institutions, who attended the lecture 'Nuclear technology: prejudice, fundamentals, applications and challenges'. Opinion surveys were done before and after each event, to know the opinions towards nuclear technology. The surveys were based on the choice of three words from about 10 not ordered stimulating keywords and each participant was invited to choose the first three ones that could represent the image he/she had when faced with the theme 'nuclear technology'. The lecture included topics covering positive and negative points of the nuclear technology. The measured results after the lectures shown positive perspective in the first images associated with the nuclear technology, despite focus on accidents was given in the final part of the event. The results show that some effectiveness on the target public was achieved in terms of bringing new perceptions on this technology. It is expected that this article can contribute somehow to the discussion of public acceptance of nuclear technology in Brazil. (author)

Data-acquisition systems for high-energy physics experiments like the ATLAS experiment at the European particle-physics research institute CERN are used to record experimental physics data and are essential for the effective operation of an experiment. Located in underground facilities with limited space, power, cooling, and exposed to ionizing radiation and strong magnetic fields, data-acquisition systems have unique requirements and are challenging to design and build. Traditionally, these systems have been composed of custom-designed electronic components to be able to cope with the large data volumes that high-energy physics experiments generate and at the same time meet technological and environmental requirements. Custom-designed electronics is costly to develop, effortful to maintain and typically not very flexible. This thesis explores an alternative architecture for data-acquisition systems based on commercial off-the-shelf (COTS) components. A COTS-based data distribution device called FELIX that w...

As originally proposed, the Space Technology-7 Disturbance Reduction System (DRS) project, managed out of the Jet Propulsion Laboratory, was designed to validate technologies required for future missions such as the Laser Interferometer Space Antenna (LISA). The two technologies to be demonstrated by DRS were Gravitational Reference Sensors (GRSs) and Colloidal MicroNewton Thrusters (CMNTs). Control algorithms being designed by the Dynamic Control System (DCS) team at the Goddard Space Flight Center would control the spacecraft so that it flew about a freely-floating GRS test mass, keeping it centered within its housing. For programmatic reasons, the GRSs were descoped from DRS. The primary goals of the new mission are to validate the performance of the CMNTs and to demonstrate precise spacecraft position control. DRS will fly as a part of the European Space Agency (ESA) LISA Pathfinder (LPF) spacecraft along with a similar ESA experiment, the LISA Technology Package (LTP). With no GRS, the DCS attitude and drag-free control systems make use of the sensor being developed by ESA as a part of the LTP. The control system is designed to maintain the spacecraft s position with respect to the test mass, to within 10 nm/the square root of Hz over the DRS science frequency band of 1 to 30 mHz.

Each year since 1980 an international training course on the implementation of States' Systems of Accounting for and Control of Nuclear Materials (SSACs) has been offered in the USA under the auspices of the Nuclear Non-Proliferation Act of 1978. The courses are sponsored by the US Department of Energy in cooperation with the International Atomic Energy Agency (IAEA) and conducted by the Los Alamos National Laboratory, with the assistance of other organizations. The purpose of the courses, which are described in detail in the paper, is ''to provide practical training in the design, implementation and operation of a national system of accounting for and control of nuclear materials that satisfies both national and IAEA international safeguards objectives.'' On odd numbered years, the course emphasis is on bulk-processing facilities; on even years the emphasis is on item-dominant facilities. Internationally known authorities are selected as course lecturers from the IAEA and Los Alamos, as well as government, industry, and national laboratories in both the USA and abroad. Lectures are supplemented with workshops, panel discussions, tours of Los Alamos safeguards laboratories, and visits to operating nuclear fuel-cycle facilities. Attendance at the 1981, 1982 and 1983 SSAC courses has averaged 26 student participants, with almost as many nations represented. The overall response to the courses has been highly favorable, indicating that they are fulfilling a timely and important need. Key to the success has been a course format that encourages maximum exchange of safeguards technology and experience among all participants, both students and lecturers. (author)

Increasing energy efficiency is discussed as an effective way to protect the climate, even though this is frequently associated with additional (investment) costs when compared to standard technologies. However, the investment costs of emerging energy-efficient technologies can be reduced by economies of scale and experience curve effects. This also brings about higher market penetration by lowering market barriers. Experience curves have already been analyzed in detail for renewable energy technologies, but are not as well documented for energy-efficient technologies despite their significance for energy and climate policy decisions. This work provides empirical evidence for effects of economies of scale and experience on the costs of energy-efficient electric motors. We apply a new methodology to the estimation of learning effects that is particularly promising for energy-efficient technologies where the very low data availability did not allow calculations of learning rates so far. Energy-efficient electric motors are a highly relevant energy technology that is responsible for about 55% of German electricity consumption. The analysis consists of three main steps. First, the calculation of composite price indices based on gross value added statistics for Germany which show the changes in cost components of electric motors over the period 1995 to 2006; second, an estimation of the corresponding learning rate which is, in a third step, compared with learning rates observed for other energy-efficient technologies in a literature review. Due to restrictions of data availability, it was not possible to calculate a learning rate for the differential costs of energy-efficient motors compared to standard motors. Still, we estimated a learning rate of 9% for 'Eff2' motors in a period when they penetrated the market and replaced the less efficient 'Eff3' motors. Furthermore, we showed the contribution of different effects to these cost reductions, like

However......, by reinterpreting his notion of "modern technology," this article shows how it is possible to philosophically assess living technologies and to recognize ways in which Heidegger anticipated this phenomenon with his notion of cybernetics. The interpretation elucidates the fundamental process of technology becoming...... living and simultaneously presents living technology as the ultimate technology. The thesis of this article is that living technology is not just one more technology; rather, it is the perfection of technology as understood by Aristotle. Aristotle's thinking is in this way a key example of a profound...

Full Text Available For many decades, cathode ray tube (CRT monitors have been the dominant display technology in vision science. However, in recent years, most manufacturers stopped their CRT production lines, which enforces the application of alternative display technology in the field of vision science. Here, we analyze liquid crystal displays (LCDs and organic light-emitting diode (OLED monitors for their applicability in vision science experiments. Based on extensive measurements of their photometric output, we compare these technologies and contrast them with classical CRT monitors. Vision scientists aim to accurately present both static and dynamic stimuli on their display devices. As for the presentation of static stimuli, we demonstrate an increased accuracy for LCD and OLED devices compared to CRT monitors, because the former exhibit a higher degree of independence of neighboring pixels. As for dynamic presentations, both CRTs and OLEDs outperform LCD devices in terms of accuracy, because dynamic presentations on LCDs require a reorientation of the liquid crystal molecules, so that successive frames in time depend on each other. Together with widely unknown and uncontrolled technical artifacts, these properties of LCDs may impair visual experiments that require high temporal precision. Therefore, OLED monitors are more suitable for vision science experiments with respect to both their static and their temporal characteristics. However, for certain applications in visual neuroscience, the low duty cycle of some OLED devices may introduce frequencies to the photometric output which fall within the window of visibility of neurons in the visual cortex and therefore interfere with single unit recordings.

Is the Moon Illusion a Celestial Ames Demonstration?
Brecher, Kenneth
2010-01-01
To most naked eye observers, the Moon appears larger when seen near the horizon than it does when seen near the zenith. This "Moon Illusion” has been reported from as early as the fourth century BC and has been the subject of hundreds of papers and two books. Its explanation does not lie in the realm of physics (atmospheric refraction) or astronomy (eccentric lunar orbit) but, rather, in the realm of visual perception. Theories for the cause of the effect abound but, at present, there is no universally accepted explanation. Because the effect can be easily observed in many locations and during the course of an academic year, the moon illusion can provide a nice astronomical example that involves both direct observations and theoretical analysis. As part of the NSF funded "Project LITE: Light Inquiry Through Experiments", we have been developing inexpensive experiments and demonstrations that can be done at home. One of these is a miniature version of the classic "Ames Room". The life size version was originally developed by Adelbert Ames, Jr. and can be seen in many science museums. Our "digital” Ames Room has been designed to be printed on heavy paper using an inexpensive inkjet printer from a PDF file that is posted on the Project LITE web site http://lite.bu.edu and then cut and folded to make the room. When viewed through one wall using a commonly available door viewer, it dramatically demonstrates how the eye and brain system assesses the relative size of objects by making comparisons with the surrounding environment in which the objects are placed. In this presentation we will discuss some insights that the Ames Room provides that may offer clues to the correct explanation for the Moon Illusion. Project LITE is supported by the NSF through DUE Grant # 0715975.

The key to the success of nuclear information management depends on whether nuclear engineers focus their attention on such management or not. This paper focus to strategic management of nuclear technology information through the KNGR NIC experience. The present KEPCO systems on nuclear information are largely divided into four parts, which are Integrated NPP Information System, System by Business Process Reengineering for Construction, KNGR IMS and Document Management Systems of Plant DDCC. In order to accommodate effective system integration, it is not desirable that a system is subordinate to others because each system has its own work flows and practices site by site. Therefore for good NIS, the system should be developed by web-based, local computer system and bottom-up approach. NIC management have to focus on domain control, nuclear portal service and development of search engine

Patients with hypertension in the community frequently fail to meet treatment goals. The optimal way to organize and deliver care to hypertensive patients has not been clearly identified. The powerful on-board computing capacity of mobile devices, along with the unique relationship individuals have with newer technologies, suggests that they have the potential to influence behaviour. However, little is known regarding the views and experiences of patients using such technology to self-manage their hypertension and associated lifestyle behaviours. The aim of this study was to explore patients' views and experiences of using technology based self-management tools for the treatment of hypertension in the community. This focus group study was conducted with known hypertensive patients over 45 years of age who were recruited in a community setting in Ireland. Taped and transcribed semi-structured interviews with a purposeful sample involving 50 participants in six focus groups were used. Framework analysis was utilized to analyse the data. Four key inter-related themes emerged from the analysis: individualisation; trust; motivation; and communication. The globalisation of newer technologies has triggered many substantial and widespread behaviour changes within society, yet users are unique in their use and interactions with such technologies. Trust is an ever present issue in terms of its potential impact on engagement with healthcare providers and motivation around self-management. The potential ability of technology to influence motivation through carefully selected and tailored messaging and to facilitate a personalised flow of communication between patient and healthcare provider was highlighted. Newer technologies such as mobile devices and the internet have been embraced across the globe despite technological challenges and concerns regarding privacy and security. In the design and development of technology based self-management tools for the treatment of

A big affection of the rock environment and groundwaters occurred during the chemical mining of uranium in the years 1966 to 1996 in the neighbourhood of the town Straz pod Ralskem in the Czech Republic. It is necessary to clean the residual technological solutions (RTS) from the underground. The pH of the solutions in some places is still less than 2 and the concentration of sulphates reaches up to 65 g/l. The remedial activities consist of pumping of the RTS from the ground and reprocessing of the RTS in the surface technologies. The implementation of the new neutralization technologies NDS ML and NDS 10 help us with increasing of the efficiency of the remedial process. The NDS ML technology ('Mother liquor reprocessing station') started its operation in 2009 and it processes the concentrated technological solution from the evaporation station after the alum crystallization (mother liquor) with the concentration of total dissolved solids up to 250 g/l. The principle is the neutralization of the acid solutions with the aid of the lime milk. The suspension is then filtrated in the filter press, the filter cake is deposited in the tailings pond and the filtrate is injected back into the underground rock environment. The NDS 10 technology ('Neutralization and Decontamination Station NDS 10') started its operation in 2012 and it works on the same technological principle as the NDS ML station. The difference is that the NDS 10 station can process higher volume (4.4 m 3 /min) of the RTS with lower concentration of total dissolved solids 20 - 25 g/l. This poster describes the experiences of the state enterprise DIAMO with putting of these two neutralization technologies into operation and with using of the lime milk neutralization in such a large scale.

Two Antarctic projects developed by solid earth scientists in the GPS and seismology communities have rich education and outreach activities focused on disseminating information gleaned from this research and on including students from underrepresented groups. Members of the UNAVCO and IRIS research consortia along with international partners from Australia, Canada, Chile, Germany, Italy, New Zealand and the U.K. aim to deploy an ambitious GPS/seismic network to observe the Antarctic glaciological and geologic system using a multidisciplinary and internationally coordinated approach. The second project supports this network. UNAVCO and IRIS are designing and building a reliable power and communication system for autonomous polar station operation which use the latest power and communication technologies for ease of deployment and reliable multi-year operation in severe polar environments. This project will disseminate research results through an IPY/POLENET web-based museum style display based on the next-generation "Museum Lite" capability primarily supported by IRIS. "Museum Lite" uses a standard PC, touch-screen monitor, and standard Internet browsers to exploit the scalability and access of the Internet and to provide customizable content in an interactive setting. The unit is suitable for research departments, public schools, and an assortment of public venues, and can provide wide access to real-time geophysical data, ongoing research, and general information. The POLENET group will work with members of the two consortia to provide content about the project and polar science in general. One unit is to be installed at Barrow's Ilisagvit College through the Barrow Arctic Science Consortium, one at McMurdo Station in Antarctica, and two at other sites to be determined (likely in New Zealand/Australia and in the U.S.). In January, 2006, Museum Lite exhibit was installed at the Amundsen-Scott South Pole Station. Evaluation of this prototype is underway. These

Recent discussions have focused on using health information technology (HIT) to support goals related to universal healthcare delivery. These discussions have generally not reflected on the experience of countries with a large amount of experience using HIT to support universal healthcare on a national level. HIT was compared globally by using data from the Ministry of the Interior, Republic of China (Taiwan). Taiwan has been providing universal healthcare since 1995 and began to strategically implement HIT on a national level at that time. Today the national-level HIT system is more extensive in Taiwan than in many other countries and is used to aid administration, clinical care, and public health. The experience of Taiwan thus can provide an illustration of how HIT can be used to support universal healthcare delivery. In this article we present an overview of some key historical developments and successes in the adoption of HIT in Taiwan over a 17-year period, as well as some more recent developments. We use this experience to offer some strategic perspectives on how it can aid in the adoption of large-scale HIT systems and on how HIT can be used to support universal healthcare delivery.

In the last 15 years there has been an increased emphasis in both educational research and curriculum development upon investigating children's perspectives of their experience of learning. Children naturally have very particular and important insights to offer in helping us to develop our understanding of teaching and learning. However, research into children's perceptions in the field of primary Design & Technology education is still at a very early stage (Lunt in International handbook of research and development in technology education, Sense Publishers, Utrecht, 2009a). For example, in three reviews of educational research in Design & Technology (Kimbell in A guide to educational research, The Woburn Publishers, London, 1996; Eggleston in Teaching and learning design and technology: a guide to recent research and its applications, Continuum, London, 2000; Harris and Wilson in Designs on the curriculum? A review of the literature on the impact of design and technology in schools, Department for Education and Skills, London, 2003) there are only passing references made to eliciting and considering pupils' views and, in the studies where it does occur, it is used as a supplementary method of data collection rather than as a focus of research. The work which exists is small-scale and the majority of studies relate to secondary-aged pupils. The research that we have recently undertaken has tried to redress this gap. It has focused on primary children's (aged 9-11 years) perceptions of Design & Technology in general (Benson and Lunt in PATT 18 international conference on design and technology educational research: teaching and learning technological literacy in the classroom, University of Glasgow, Glasgow, 2007) and latterly creativity in Design & Technology. It has been claimed by many that Design & Technology is a `creative' subject which develops children's creative abilities. This is a bold claim and one that needs careful consideration.

Full Text Available O objetivo deste trabalho foi identificar marcadores microssatélites ligados ao loco de características quantitativas (QTL responsável pelo escurecimento tardio do tegumento de feijões do tipo carioca, a fim de reduzir o tempo de avaliação necessário para seleção quanto a essa característica. Foram utilizados dados de avaliação fenotípica de 185 progênies F2:3 derivadas do cruzamento VC-3 x 'BRSMG Majestoso', para o estudo do controle genético do escurecimento dos grãos. Com esses dados, foram confeccionados dois "bulks" segregantes de DNA, empregados para a avaliação de 444 pares de primers SSR. Os aplicativos computacionais GQMOL e Sisvar foram utilizados para avaliar as segregações, confeccionar um grupo de ligação e realizar análises de marca simples e de regressão múltipla pelo método "backward". Oito marcadores apresentaram polimorfismo nos "bulks". Seis desses marcadores foram agrupados em um grupo de ligação de 80,49 cM, e destes, três mostraram-se estreitamente ligados ao QTL responsável pelo escurecimento tardio dos grãos. O marcador PVM02TC116 cossegregou com o QTL em questão, e os marcadores PVESTBR-98 (2,00 cM e PV176 (12,24 cM flanqueiam essa região, o que sugere elevada eficiência para possível uso na seleção assistida.

The High Throughput Computing paradigm typically involves a scenario whereby a given, estimated processing power is made available and sustained by the computing environment over a medium/long period of time. As a consequence, the performance goals are in general targeted at maximizing resource utilization to obtain the expected throughput, rather than minimizing run time for individual jobs. This does not mean that optimal resource selection through adequate workload management is not desired nor effective, nonetheless, relatively small and pre-assessed percentages of suboptimal choices or unexpected events can be tolerated. However, there are use-cases, among the HEP community, for which the described model does not immediately fit. This paper deals with the workload needs primarily driven by the Collider Detector at Fermilab (CDF) experimental collaboration. In particular, the CDF analysis facility (CAF) typically operates by splitting its computations into so-called sections, which can be seen as sets of uniform and independent jobs. Processing a section cannot be considered completed until all its jobs have been successfully executed, thus requiring a Minimum Completion Time (MCT) dynamic scheduling policy where not even a single job should lay in non-terminal Grid states. A significant part of the CDF analysis is processed on the European Grid infrastructure through the gLite Workload Management System (WMS). This paper describes the design enhancements and ranking algorithms the WMS has been provided with to implement an adaptive scheduling policy to minimise MCT. Case study, outlined approach and first results are presented.
