AutoPyFactory: A Scalable Flexible Pilot Factory Implementation

Caballero, J; Hover, J; Love, P; Stewart, G A

2012-01-01

The ATLAS experiment at the CERN LHC is one of the largest users of grid computing infrastructure, which is a central part of the experiment's computing operations. Considerable efforts have been made to use grid technology in the most efficient and effective way, including the use of a pilot job based workload management framework. In this model the experiment submits ‘pilot’ jobs to sites without payload. When these jobs begin to run they contact a central service to pick-up a real payload to execute. The first generation of pilot factories were usually specific to a single Virtual Organization (VO), and were bound to the particular architecture of that VO's distributed processing. A second generation provides factories which are more flexible, not tied to any particular VO, and provide new and improved features such as monitoring, logging, profiling, etc. In this paper we describe this key part of the ATLAS pilot architecture, a second generation pilot factory, AutoPyFactory. AutoPyFactory has a modular design and is highly configurable. It is able to send different types of pilots to sites and exploit different submission mechanisms and queue characteristics. It is tightly integrated with the PanDA job submission framework, coupling pilot flow to the amount of work the site has to run. It gathers information from many sources in order to correctly configure itself for a site and its decision logic can easily be updated. Integrated into AutoPyFactory is a flexible system for delivering both generic and specific job wrappers which can perform many useful actions before starting to run end-user scientific applications, e.g., validation of the middleware, node profiling and diagnostics, and monitoring. AutoPyFactory also has a robust monitoring system that has been invaluable in establishing a reliable pilot factory service for ATLAS.

Chung, M. J.; Kim, C. Y.

2018-03-01

In this study, we proposed integrated control system for automation of injection molding process required for construction of smart factory. The injection molding process consists of heating, tool close, injection, cooling, tool open, and take-out. Take-out robot controller, image processing module, and process data acquisition interface module are developed and assembled to integrated control system. By adoption of integrated control system, the injection molding process can be simplified and the cost for construction of smart factory can be inexpensive.

Insulin-like growth factor-I, physical activity, and control of cellular anabolism.

Science.gov (United States)

Nindl, Bradley C

2010-01-01

The underlying mechanisms responsible for mediating the beneficial outcomes of exercise undoubtedly are many, but the insulin-like growth factor-I (IGF-I) system is emerging as an important and central hormonal axis that plays a significant role concerning cellular anabolism. This introductory article summarizes the intent and the content for papers presented as part of a 2008 American College of Sports Medicine national symposium entitled "Insulin-like Growth Factor-I, Physical Activity, and Control of Cellular Anabolism." The individual authors and their papers are as follows: Jan Frystyk authoring "The relationship between exercise and the growth hormone/insulin-like growth factor-I axis," Greg Adams authoring "IGF-I signaling in skeletal muscle and the potential for cytokine interactions," and Brad Nindl authoring "Insulin-like growth factor-I as a biomarker of health, fitness, and training status." These papers focus on 1) different assay methodologies for IGF-I within the paradigm of exercise studies, 2) research demonstrating that intracellular signaling components associated with several proinflammatory cytokines have the potential to interact with anabolic signaling processes in skeletal muscle, and 3) an overview of IGF-I as a biomarker related to exercise training, muscle and bone remodeling, body composition, cognition, and cancer. When summed in total, the contribution that these papers will make will undoubtedly involve bringing attention to the vast regulatory complexity of the IGF-I system and will hopefully convince the reader that the IGF-I system warrants further detailed scientific inquiry to resolve many unanswered questions and paradoxical experimental findings. The IGF-I system remains one of the most intriguing and captivating marvels of human physiology that seems central in mediating numerous adaptations from physical activity.

B factories present unique requirements for controls and instrumentation systems. High reliability is critical to achieving the integrated luminosity goals. The CESR-B upgrade at Cornell University will have a control system based on the architecture of the successful CESR control system, which uses a centralized database/massage routing system in a multiported memory, and VAX stations for all high-level control functions. The implementation of this architecture will address the deficiencies in the current implementation while providing the required performance and reliability. (author)

A Hospital Is Not Just a Factory, but a Complex Adaptive System-Implications for Perioperative Care.

Science.gov (United States)

Mahajan, Aman; Islam, Salim D; Schwartz, Michael J; Cannesson, Maxime

2017-07-01

Many methods used to improve hospital and perioperative services productivity and quality of care have assumed that the hospital is essentially a factory, and therefore, that industrial engineering and manufacturing-derived redesign approaches such as Six Sigma and Lean can be applied to hospitals and perioperative services just as they have been applied in factories. However, a hospital is not merely a factory but also a complex adaptive system (CAS). The hospital CAS has many subsystems, with perioperative care being an important one for which concepts of factory redesign are frequently advocated. In this article, we argue that applying only factory approaches such as lean methodologies or process standardization to complex systems such as perioperative care could account for difficulties and/or failures in improving performance in care delivery. Within perioperative services, only noncomplex/low-variance surgical episodes are amenable to manufacturing-based redesign. On the other hand, complex surgery/high-variance cases and preoperative segmentation (the process of distinguishing between normal and complex cases) can be viewed as CAS-like. These systems tend to self-organize, often resist or react unpredictably to attempts at control, and therefore require application of CAS principles to modify system behavior. We describe 2 examples of perioperative redesign to illustrate the concepts outlined above. These examples present complementary and contrasting cases from 2 leading delivery systems. The Mayo Clinic example illustrates the application of manufacturing-based redesign principles to a factory-like (high-volume, low-risk, and mature practice) clinical program, while the Kaiser Permanente example illustrates the application of both manufacturing-based and self-organization-based approaches to programs and processes that are not factory-like but CAS-like. In this article, we describe how factory-like processes and CAS can coexist within a hospital and how

In-Factory Learning - Qualification For The Factory Of The Future

Science.gov (United States)

Quint, Fabian; Mura, Katharina; Gorecky, Dominic

2015-07-01

The Industry 4.0 vision anticipates that internet technologies will find their way into future factories replacing traditional components by dynamic and intelligent cyber-physical systems (CPS) that combine the physical objects with their digital representation. Reducing the gap between the real and digital world makes the factory environment more flexible, more adaptive, but also more complex for the human workers. Future workers require interdisciplinary competencies from engineering, information technology, and computer science in order to understand and manage the diverse interrelations between physical objects and their digital counterpart. This paper proposes a mixed-reality based learning environment, which combines physical objects and visualisation of digital content via Augmented Reality. It uses reality-based interaction in order to make the dynamic interrelations between real and digital factory visible and tangible. We argue that our learning system does not work as a stand-alone solution, but should fit into existing academic and advanced training curricula.

Fletcher, Eugene; Krivoruchko, Anastasia; Nielsen, Jens

2016-06-01

Engineering industrial cell factories to effectively yield a desired product while dealing with industrially relevant stresses is usually the most challenging step in the development of industrial production of chemicals using microbial fermentation processes. Using synthetic biology tools, microbial cell factories such as Saccharomyces cerevisiae can be engineered to express synthetic pathways for the production of fuels, biopharmaceuticals, fragrances, and food flavors. However, directing fluxes through these synthetic pathways towards the desired product can be demanding due to complex regulation or poor gene expression. Systems biology, which applies computational tools and mathematical modeling to understand complex biological networks, can be used to guide synthetic biology design. Here, we present our perspective on how systems biology can impact synthetic biology towards the goal of developing improved yeast cell factories. Biotechnol.

The fourth industrial revolution promises to create what has been called the smart factory. The vision is that within such modular structured smart factories, cyber-physical systems monitor physical processes, create a virtual copy of the physical world and make decentralised decisions. This paper provides a view of this initiative from an automation systems perspective. In this context it considers how future automation systems might be effectively configured and supported through their lifecycles and how integration, application modelling, visualisation and reuse of such systems might be best achieved. The paper briefly describes limitations in current engineering methods, and new emerging approaches including the cyber physical systems (CPS) engineering tools being developed by the automation systems group (ASG) at Warwick Manufacturing Group, University of Warwick, UK.

The Nearby Supernova Factory (SNfactory) is an international experiment designed to lay the foundation for the next generation of cosmology experiments (such as CFHTLS, wP, SNAP and LSST) which will measure the expansion history of the Universe using Type Ia supernovae. The SNfactory will discover and obtain frequent lightcurve spectrophotometry covering 3200-10000 (angstrom) for roughly 300 Type Ia supernovae at the loW--redshift end of the smooth Hubble flow. The quantity, quality, breadth of galactic environments, and homogeneous nature of the SNfactory dataset will make it the premier source of calibration for the Type Ia supernova width-brightness relation and the intrinsic supernova colors used for K-correction and correction for extinction by host-galaxy dust. This dataset will also allow an extensive investigation of additional parameters which possibly influence the quality of Type Ia supernovae as cosmological probes. The SNfactory search capabilities and folloW--up instrumentation include wide-field CCD imagers on two 1.2-m telescopes (via collaboration with the Near Earth Asteroid Tracking team at JPL and the QUEST team at Yale), and a two-channel integral-field-unit optical spectrograph/imager being fabricated for the University of Hawaii 2.2-m telescope. In addition to ground-based folloW--up, UV spectra for a subsample of these supernovae will be obtained with HST. The pipeline to obtain, transfer via wireless and standard internet, and automatically process the search images is in operation. Software and hardware development is now underway to enable the execution of folloW--up spectroscopy of supernova candidates at the Hawaii 2.2-m telescope via automated remote control of the telescope and the IFU spectrograph/imager

Down sampled signal processing for a B Factory bunch-by-bunch feedback system

Hindi, H.; Hosseini, W.; Briggs, D.; Fox, J.; Hutton, A.

1992-03-01

A bunch-by-bunch feedback scheme is studied for damping coupled bunch synchrotron oscillations in the proposed PEP II B Factory. The quasi-linear feedback systems design incorporates a phase detector to provide a quantized measure of bunch phase, digital signal processing to compute an error correction signal and a kicker system to correct the energy of the bunches. A farm of digital processors, operating in parallel, is proposed to compute correction signals for the 1658 bunches of the B Factory. This paper studies the use of down sampled processing to reduce the computational complexity of the feedback system. We present simulation results showing the effect of down sampling on beam dynamics. Results show that down sampled processing can reduce the scale of the processing task by a factor of 10

The U.S. is addicted to petroleum--a dependency that periodically shocks the economy, compromises national security, and adversely affects the environment. If liquid fuels remain the main energy source for U.S. transportation for the foreseeable future, the system solution is the production of new liquid fuels that can directly displace diesel and gasoline. This study focuses on advanced concepts for biofuel factory production, describing three design concepts: biopetroleum, biodiesel, and higher alcohols. A general schematic is illustrated for each concept with technical description and analysis for each factory design. Looking beyond current biofuel pursuits by industry, this study explores unconventional feedstocks (e.g., extremophiles), out-of-favor reaction processes (e.g., radiation-induced catalytic cracking), and production of new fuel sources traditionally deemed undesirable (e.g., fusel oils). These concepts lay the foundation and path for future basic science and applied engineering to displace petroleum as a transportation energy source for good.

Chen, Wei-Tai; Yeh, Yu-Hui F; Liu, Ting-Yu; Lin, Ta-Te

2016-01-01

In plant factories, plants are usually cultivated in nutrient solution under a controllable environment. Plant quality and growth are closely monitored and precisely controlled. For plant growth evaluation, plant weight is an important and commonly used indicator. Traditional plant weight measurements are destructive and laborious. In order to measure and record the plant weight during plant growth, an automated measurement system was designed and developed herein. The weight measurement system comprises a weight measurement device and an imaging system. The weight measurement device consists of a top disk, a bottom disk, a plant holder and a load cell. The load cell with a resolution of 0.1 g converts the plant weight on the plant holder disk to an analog electrical signal for a precise measurement. The top disk and bottom disk are designed to be durable for different plant sizes, so plant weight can be measured continuously throughout the whole growth period, without hindering plant growth. The results show that plant weights measured by the weight measurement device are highly correlated with the weights estimated by the stereo-vision imaging system; hence, plant weight can be measured by either method. The weight growth of selected vegetables growing in the National Taiwan University plant factory were monitored and measured using our automated plant growth weight measurement system. The experimental results demonstrate the functionality, stability and durability of this system. The information gathered by this weight system can be valuable and beneficial for hydroponic plants monitoring research and agricultural research applications.

Factory automation for heavy electric equipment

The heightening of productivity in the factories manufacturing heavy electric equipment has been advanced so far by the rationalization of direct workings such as NC, robots and the adoption of FMS (flexible manufacturing system). However, as CAD advances, the effective utilization of these data and the expansion to future CIM (computer integrated manufacture) have become to be demanded. In the Hitachi Works of Hitachi Ltd., it was decided to advance the synthetic rationalization by adopting FA (factory automation) system. Steam turbine blades, pipings for nuclear power plants and motor coils were taken up as the objects since these are important parts, and for the purpose of the drastic heightening of QA level, the heightening of accuracy and the shortening of processes, the synchronization with field installation schedule and the creation of safe working place environment, the FA projects for these three sections were simultaneously planned. When the automation of non-mass production factories is promoted, there are the unmanned factories combining FMS lines for relatively many products and those characterized by FMC of shortening preparation time for small lot products, and this is the examples of the former. The system constitution for FA and the production management combined with it are described. The high reliability of the optical network was regarded as important. (Kako, I.)

Since about three or four years ago, the enterprises of machinery, iron and steel and welding materials in Japan are paying much attention to the acquisition of ASME (American Society of Mechanical Engineers) certificates or authorization to stamp the code symbols. That is, over 70 factories in Japan have undergone ASME examination, and consequently acquired the authorization or certificates. Such authorization is divided into over 20 kinds, of which about 7 are possessed by the companies in Japan. In nuclear field, the kinds of authorization are N (nuclear vessel), NPT (nuclear vessel parts), NV (nuclear vessel safety valve), and MM (material manufacturing). In non-nuclear fields, they are S (power boilers), U (pressure vessels, in Div. 1), and U2 (pressure vessels in Div. 2). The following matters are described: ASME setup, authorization procedures of ASME for factories, the kinds of authorization, factories in Japan holding the authorization or certificates, and renewal of the authorization.

The asymmetric energy B Factory proposed as an upgrade of PEP at Stanford Linear Accelerator Center will require a highly reliable and efficient injection system. The conceptual design has shown the feasibility of extracting 9 GeV electrons and 3.1 GeV positrons from the existing linac and injecting equal charges into 1658 buckets in each of the two rings of the collider. An injection study group has continued the development and study of this proposal and has generated workable designs for many related systems and subsystems. (author) 3 refs.; 4 figs.; 2 tabs

1998-05-01

At the 2.5 GeV ring of the Photon Factory, a single-pass beam-position monitor (BPM) system is being prepared for the storage ring and the beam transport line. In the storage ring, the injected beam position during the first several turns can be measured with a single injection pulse. The BPM system has an adequate performance, useful for the commissioning of the new low-emittance lattice. Several stripline BPMs are being installed in the beam transport line. The continuous monitoring of the orbit in the beam transport line will be useful for the stabilization of the injection energy as well as the injection beam orbit.

AutoPyFactory: A Scalable Flexible Pilot Factory Implementation

CERN Document Server

Caballero, J; The ATLAS collaboration; Love, P; Stewart, G

2012-01-01

The ATLAS experiment at the CERN LHC is one of the largest users of grid computing infrastructure, which is a central part of the experiment’s computing operations. Considerable efforts have been made to use grid technology in the most efficient and effective way, including the use of a pilot job based workload management framework. In this model the experiment submits ’pilot’ jobs to sites without payload. When these jobs begin to run they contact a central service to retrieve a real payload to execute. The first generation of pilot factories were usually specific to a single VO, and were bound to the particular architecture of that VO’s distributed processing. A second generation provides factories which are more flexible, not tied to any particular VO, and provide new or improved features such as monitoring, logging, profiling, etc. In this paper we describe this key part of the ATLAS pilot architecture, a second generation pilot factory, AutoPyFactory. AutoPyFactory has a modular design and is hig...

Energetic sector in SARTID Iron and Steel factory includes complex systems for production, transformation and distribution of all kinds of energy and fluids, supplying all other production divisions. As that, energetic sector has large influence in environment. Incorporating quality system ISO 14001 in SARTID factory, with special care we are working on environment protection monitoring system. Having started with this, as first we are working on implementation of monitoring system for air pollution from our emitters of exhausted gases issued from incineration of blast furnace (BF) gas, natural gas and crude oil. Constant recording of air pollutant emissions from our boilers have became standard procedure now. This monitoring system is based on software package, where input data are permanently measured flow of fuels, fuel composition and quality of combustion. As a result, in each time we know quantity of emitted exhausted components - CO 2 , CO, SO 2 , (NO) x . Another monitoring system that we are implementing right now is some simpler, being used for a lot of smaller BF or natural gas consumers. (Original)

Highlights: • Hybrid MPPT method was developed and utilized in a PV system of closed plant factory. • The tracking of the maximum power output of PV system can be achieved in real time. • Hybrid MPPT method not only decreases energy loss but increases power utilization. • The feasibility of applying PV system to the closed plant factory has been examined. • The PV system significantly reduced CO 2 emissions and curtailed the fossil fuels. - Abstract: Photovoltaic (PV) generation systems have been shown to have a promising role for use in high electric-load buildings, such as the closed plant factory which is dependent upon artificial lighting. The power generated by the PV systems can be either directly supplied to the buildings or fed back into the electrical grid to reduce the high economic costs and environmental impact associated with the traditional energy sources such as nuclear power and fossil fuels. However, PV systems usually suffer from low energy-conversion efficiency, and it is therefore necessary to improve their performance by tackling the energy loss issues. The maximum power point tracking (MPPT) control technique is essential to the PV-assisted generation systems in order to achieve the maximum power output in real time. In this study, we integrate the previously proposed direct-prediction MPP method with a perturbation and observation (P and O) method to develop a new hybrid MPPT method. The proposed MPPT method is further utilized in the PV inverters in a PV system installed on the roof of a closed plant factory at National Taiwan University. The tested PV system is constructed as a two-stage grid-connected photovoltaic power conditioning (PVPC) system with a boost-buck full bridge design configuration. A control scheme based on the hybrid MPPT method is also developed and implemented in the PV inverters of the PVPC system to achieve tracking of the maximum power output of the PV system in real time.

sufficient titers. To improve the production of polyketides biological engineering principles have been applied for the development and engineering of microbial polyketide cell factories. The two biological hosts used for heterologous polyketide production were Aspergillus nidulans and Saccharomyces...... phosphopantetheinylase (PPTase). This versatile vector system can easily be used for expression of other polyketides of interest as well as extended to express whole gene clusters. After achieving proof of principle in terms of expression, the polyketide cell factory must be optimized. The optimization can be achieved...... characterization in bioreactors revealed that the yields of 6-MSA on biomass increased albeit not significantly. As a result of this it may be argued that there is still more work to be done in terms of model building in A. nidulans. Utilizing another well-established cell factory S. cerevisiae the capabilities...

The kaon factory - towards the physics of strongly interacting systems

International Nuclear Information System (INIS)

Vogt, Erich

1988-01-01

With the advent of the standard model for quarks and leptons and unified forces there are profound new questions for the physics of strongly interacting systems: the nature of the nucleon, the physics of quark confinement, fundamental symmetries governing hadron decay and the effect of quarks and gluons on nuclear behaviour. Of the new large facilities now planned to respond to these questions the kaon factory is central. It uses very intense (∼100 μA) primary proton beams (∼30 GeV) to generate intense secondary beams of various hadrons and leptons. (author)

1991-01-01

The proposed asymmetric energy B Factory to be built in the PEP tunnel at SLAC will require a highly effective and profuse source of low emittance electron and positron bunches. The B Factory will consist of two rings of equal size, a 9 GeV electron ring and a 3.1 GeV positron ring, each with 1658 bunches with total circulating currents of 1.5 and 2.1 amperes respectively. As the luminosity lifetime of the collider is expected to be about two hours, the injector should be capable of filling the rings in a small fraction of an hour. It turns out that with some simple modifications, the SLC linac with its damping rings and positron source is ideally suited to fulfill this function effectively. The overall injection system is described

Vacuum system of the high energy ring of an asymmetric B-factory based on PEP

International Nuclear Information System (INIS)

Barletta, W.A.; Calderon, M.O.; Wong, R.; Jenkins, T.M.

1991-01-01

The multi-ampere currents required for high luminosity operation of an asymmetric B factory leads to extremely stressing requirements on a vacuum system suitable for maintaining long beam-gas lifetimes and acceptable background levels in the detector. We present the design for a Cu alloy vacuum chamber and its associated pumping system for the 9 GeV electron storage ring of the proposed B factory based on PEP. The excellent thermal and photo-desorption properties of Cu allows handling the high proton flux in a conventional, single chamber design with distributed ion pumps. The x-ray opacity of the Cu is sufficiently high that no additional lead shielding is necessary to protect the dipoles from the intense synchrotron radiation generated by the beam. The design allows chamber commissioning in <500 hr of operation. 5 refs., 3 figs., 2 tabs

In addition to hearing the latest experimental and theoretical developments at the 17th International Symposium on Lepton Photon Interactions in Beijing, delegates were brought up-to-date on the substantial progress towards the realization of a Tau-Charm Factory in the Chinese capital. Opening the Symposium, Zhou Guangzhao, President of the Chinese Academy of Sciences, expressed a commitment of the Chinese government to basic research and its interest in the continuing development high energy physics in China. Following the very successful construction and operation of Beijing's Electron-Positron Collider, BEPC, the Chinese government has provided 5M yuan ($US 600,000) for a feasibility study by the end of 1996 for a Tau-Charm Factory at Beijing's Institute of High Energy Physics (IHEP). Professor Zhou expressed his belief that, once approved, such a factory would greatly enhance high energy physics in China. He warmly welcomed international collaboration both in the construction of the accelerator and in the experimental programme. His comments were reinforced in the following welcome speech by IHEP Director Zheng Zhipeng. Conference delegates had the opportunity to inspect the BEPC injector and collider, built almost entirely by Chinese industry. The International Committee for Future Accelerators (ICFA) met during the Symposium, with Tau- Charm Factory business on the agenda. In his subsequent report, ICFA Chairman John Peoples said that a Tau-Charm Factory provides a unique experimental environment for the precision studies of tau, charm and light quark-gluon spectroscopy, and that some issues in these fields are not satisfactorily addressed solely by B Factories or fixed-target experiments.

Growth rates of coherent beam oscillations are faster than the natural damping mechanisms for the parameters of the PEP-II B-factory storage rings at nominal currents, even with damping of cavity higher order modes (HOM's). With 165 8 bunches separated by 4.2 ns, and a large current of up to 3A (2.14 A nominal in the low energy ring), many coupled-bunch modes are excited by the resistive wall impedance and cavity higher order mode impedance. Fastest growth times of transverse rigid-bunch modes of approximately 300 ps are expected, two orders of magnitude faster than the radiation damping time. We will provide broadband, bunch-by-bunch feedback to suppress this coherent motion of the beam. Experience gained with a prototype system, installed and successfully operating at the LBNL Advanced Light Source (ALS), has been used extensively in developing the design of the PEP-II systems

Putting Automated Visual Inspection Systems To Work On The Factory Floor: What's Missing?

Science.gov (United States)

Waltz, Frederick M.; Snyder, Michael A.; Batchelor, Bruce G.

1990-02-01

Machine vision systems and other automated visual inspection (AVI) systems have been proving their usefulness in factories for more than a decade. In spite of this, the number of installed systems is far below the number that could profitably be employed. In the opinion of the authors, the primary reason for this is the high cost of customizing vision systems to meet applications requirements. A three-part approach to this problem has proven to be useful: 1. A multi-phase paradigm for customer interaction, system specification, system development, and system installation; 2. A powerful and easy-to-use system development environment, including a a flexible laboratory lighting setup, plus software-based tools to assist in the design of image acquisition systems, b. an image processing environment with a very large repertoire of image processing and feature extraction operations and an easy-to-use command interpreter having macro capabilities, and c. an image analysis environment with high-level constructs, a flexible and powerful syntax, and a "seamless" interface to the image processing level; and 3. A moderately-priced high-speed "target" system fully compatible with the development environment, so that algorithms developed thereon can be transferred directly to the factory environment without further development costs or reprogramming. Items 1 and 2 are covered in other papers1,23,4,5 and are touched on here only briefly. Item 3 is the main subject of this paper. Our major motivation in presenting this paper is to offer suggestions to vendors developing commercial boards and systems, in hopes that the special needs of industrial inspection can be met.

Accommodating more and more distributed PhotoVoltaic (PV) systems within load pockets has changed the shape of distribution grids. It is not, therefore, accurate anymore to address distribution grids just only as a lumped load. So it will be crucial in the near future to have an aggregate model of PV systems in distribution grids. By doing so, it is important to develop models for PV systems in different simulation platforms to study their behavior in order to derive an aggregate model of them. Although, there have been several detailed-switching model of a PV system in EMTDC/PSCAD simulation platform in literature, these non-proprietary switching models are slow in simulation, particularly when the number of the PV systems increases on the grounds that in PSCAD the simulation is based on time domain instantaneous values and requires more mathematical details of components. Therefore, in this paper a model of the PV system in DIgSILENT/Power Factory is developed, which is a proper environment to run rms simulation and works based on the phasors, and, moreover, from mathematical perspective is more simplified. The performance of the stemming model is compared with the switching model in PSCAD. Comparing the simulation results of the proposed model in PowerFactory with the model in PSCAD shows the credibility and accuracy of the proposed model. (orig.)

Overview of LLRF Systems

2005-01-01

In the past two decades accelerator controls and feedback systems have changed dramatically. While in the past relative simple analog systems where used, present systems are highly complex, and all accelerators in planning or under construction heavily relay on advanced feedback and feedforward control schemes. The Low-Level-Radio-Frequency (LLRF) system not only stabilizes the field in the RF cavities, but also has to provide among other things frequency control, exception handling, extensive diagnostic, and performance and machine availability maximization. As manifold as the tasks are for the LLRF system, so are the challenges. Linac driven light sources require highest field stability, while pulsed machines or low beta linacs bring their own challenges for the LLRF system. This presentation reviews the challenges and demands on present and future LLRF systems, gives an overview of state-of-the-art solutions, and an introduction into a very active and exciting field of accelerator physics.

A conceptual design of circular Higgs factory

Energy Technology Data Exchange (ETDEWEB)

Cai, Yunhai

2016-11-30

Similar to a super B-factory, a circular Higgs factory (CHF) will require strong focusing systems near the interaction points and a low-emittance lattice in the arcs to achieve a factory luminosity. At electron beam energy of 125 GeV, beamstrahlung effects during the collision pose an additional challenge to the collider design. In particular, a large momentum acceptance at the 2% level is necessary to retain an adequate beam lifetime. This turns out to be the most challenging aspect in the design of a CHF. In this paper, an example will be provided to illustrate the beam dynamics in a CHF, emphasizing the chromatic optics. Basic optical modules and advanced analysis will be presented. Most importantly, we will show that 2% momentum aperture is achievable.

Full Text Available Arm support systems provide support throughout daily tasks, training or in an industrial environment. During the last decades a large diversity of actuated arm support systems have been developed. To analyze the actuation principles in these systems, an overview of actuated arm support systems is provided. This overview visualizes the current trends on research and development of these support systems and distinguishes three categories. These categories depend mainly on the functional status of the user environment, which defines the specifications. Therefore, the actuated arm support systems are classified according to their user environment, namely: ambulatory, rehabilitation and industrial. Furthermore, three main actuation principles and three mechanical construction principles have been identified.

Feasible designs are well advanced for high-luminosity e + e - storage rings which produce B 0 bar B 0 pairs either at rest or, in what appears to be a more promising option, boosted in the detector frame. Facilities which could provide samples of 30--100 fb -1 per year on the Υ(4S) will be proposed in early 1991. Here we examine the principal physics goal of such B Factories, namely CP violation in the b system. Methods in a variety of channels, estimated event samples, and detector requirements are all considered. We conclude that the physics argument for an e + e - B Factory is well documented, and compelling. 50 refs., 22 figs., 10 tabs

1998-05-01

Accompanying the brilliance-upgrading project at the Photon Factory storage ring, the beam-position monitor (BPM) system has been renovated. The new system was designed to enable precise and fast measurements to correct the closed-orbit distortion (COD), as well as to feed back the orbit position during user runs. There are 42 BPMs newly installed, amounting to a total of 65 BPMs. All of the BPMs are calibrated on the test bench using a coaxially strung metallic wire. The measured electrical offsets are typically 200 micro m in both directions, which is 1/2-1/3 of those of the old-type BPMs. In the signal-processing system, PIN diode switches are employed in order to improve reliability. In the fastest mode, this system is capable of measuring COD within about 10 ms; this fast acquisition will allow fast suppression of the beam movement for frequencies up to 50 Hz using a global feedback system.

Performance Prediction of a MongoDB-Based Traceability System in Smart Factory Supply Chains.

2016-12-14

In the future, with the advent of the smart factory era, manufacturing and logistics processes will become more complex, and the complexity and criticality of traceability will further increase. This research aims at developing a performance assessment method to verify scalability when implementing traceability systems based on key technologies for smart factories, such as Internet of Things (IoT) and BigData. To this end, based on existing research, we analyzed traceability requirements and an event schema for storing traceability data in MongoDB, a document-based Not Only SQL (NoSQL) database. Next, we analyzed the algorithm of the most representative traceability query and defined a query-level performance model, which is composed of response times for the components of the traceability query algorithm. Next, this performance model was solidified as a linear regression model because the response times increase linearly by a benchmark test. Finally, for a case analysis, we applied the performance model to a virtual automobile parts logistics. As a result of the case study, we verified the scalability of a MongoDB-based traceability system and predicted the point when data node servers should be expanded in this case. The traceability system performance assessment method proposed in this research can be used as a decision-making tool for hardware capacity planning during the initial stage of construction of traceability systems and during their operational phase.

The author surveys the range of nuclear physics issues which can be addressed with a high intensity hadron facility such as the KAON factory. He discusses hadron spectroscopy, kaon scattering, hypernuclear physics, spin physics, and nuclear physics with neutrinos. Nuclear Physics is defined rather broadly, encompassing the study of strongly interacting systems, and including the structure of individual hadrons, hadron-hadron interactions, hadronic weak and electromagnetic currents (in nuclei too), conventional nuclear structure, and exotic nuclei. The basic theme is how the KAON Factory can shed light on non-perturbative QCD and its relation to conventional nuclear physics

Rapid prototyping 3D virtual world interfaces within a virtual factory environment

On-going work into user requirements analysis using CLIPS (NASA/JSC) expert systems as an intelligent event simulator has led to research into three-dimensional (3D) interfaces. Previous work involved CLIPS and two-dimensional (2D) models. Integral to this work was the development of the University of Massachusetts Lowell parallel version of CLIPS, called PCLIPS. This allowed us to create both a Software Bus and a group problem-solving environment for expert systems development. By shifting the PCLIPS paradigm to use the VEOS messaging protocol we have merged VEOS (HlTL/Seattle) and CLIPS into a distributed virtual worlds prototyping environment (VCLIPS). VCLIPS uses the VEOS protocol layer to allow multiple experts to cooperate on a single problem. We have begun to look at the control of a virtual factory. In the virtual factory there are actors and objects as found in our Lincoln Logs Factory of the Future project. In this artificial reality architecture there are three VCLIPS entities in action. One entity is responsible for display and user events in the 3D virtual world. Another is responsible for either simulating the virtual factory or communicating with the real factory. The third is a user interface expert. The interface expert maps user input levels, within the current prototype, to control information for the factory. The interface to the virtual factory is based on a camera paradigm. The graphics subsystem generates camera views of the factory on standard X-Window displays. The camera allows for view control and object control. Control or the factory is accomplished by the user reaching into the camera views to perform object interactions. All communication between the separate CLIPS expert systems is done through VEOS.

Construction of new data archive system in RIKEN RI beam factory

International Nuclear Information System (INIS)

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

2012-01-01

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

Neutrino factories

The discovery of neutrino oscillations marks a major milestone in the history of neutrino physics, and opens a window to what lies beyond the Standard Model. Many current and forthcoming experiments will answer open questions; however, a major step forward, up to and possibly including CP violation in the neutrino mixing matrix, will be offered by the neutrino beams from a neutrino factory. The neutrino factory is a new concept for producing neutrino beams of unprecedented quality in terms of intensity, flavour composition, and precision of the beam parameters. These beams enable the exploration of otherwise inaccessible domains in neutrino oscillation physics by exploiting baselines of planetary dimensions. Suitable detectors pose formidable challenges but seem within reach with only moderate extrapolations from existing technologies. Although the main physics attraction of the neutrino factory is in the area of neutrino oscillations, an interesting spectrum of further opportunities ranging from high-precision, high-rate neutrino scattering to physics with high-intensity stopped muons comes with it

The properties of the neutrino provide a unique window on physics beyond that described by the standard model. The study of subleading effects in neutrino oscillations, and the race to discover CP-invariance violation in the lepton sector, has begun with the recent discovery that $\\theta_{13} > 0$. The measured value of $\\theta_{13}$ is large, emphasizing the need for a facility at which the systematic uncertainties can be reduced to the percent level. The neutrino factory, in which intense neutrino beams are produced from the decay of muons, has been shown to outperform all realistic alternatives and to be capable of making measurements of the requisite precision. Its unique discovery potential arises from the fact that only at the neutrino factory is it practical to produce high-energy electron (anti)neutrino beams of the required intensity. This paper presents the conceptual design of the neutrino factory accelerator facility developed by the European Commission Framework Programme 7 EURO$\

Transportation fuels will gradually shift from oil based fuels towards alternative fuel resources like biofuels. Current bioethanol and biodiesel can, however, not cover the increasing demand for biofuels and there is therefore a need for advanced biofuels with superior fuel properties. Novel cell factories will provide a production platform for advanced biofuels. However, deep cellular understanding is required for improvement of current biofuel cell factories. Fast screening and analysis (-omics) methods and metabolome-wide mathematical models are promising techniques. An integrated systems approach of these techniques drives diversity and quantity of several new biofuel compounds. This review will cover the recent technological developments that support improvement of the advanced biofuels 1-butanol, biodiesels and jetfuels. Copyright © 2011 Elsevier Ltd. All rights reserved.

2016-01-01

In the future, with the advent of the smart factory era, manufacturing and logistics processes will become more complex, and the complexity and criticality of traceability will further increase. This research aims at developing a performance assessment method to verify scalability when implementing traceability systems based on key technologies for smart factories, such as Internet of Things (IoT) and BigData. To this end, based on existing research, we analyzed traceability requirements and an event schema for storing traceability data in MongoDB, a document-based Not Only SQL (NoSQL) database. Next, we analyzed the algorithm of the most representative traceability query and defined a query-level performance model, which is composed of response times for the components of the traceability query algorithm. Next, this performance model was solidified as a linear regression model because the response times increase linearly by a benchmark test. Finally, for a case analysis, we applied the performance model to a virtual automobile parts logistics. As a result of the case study, we verified the scalability of a MongoDB-based traceability system and predicted the point when data node servers should be expanded in this case. The traceability system performance assessment method proposed in this research can be used as a decision-making tool for hardware capacity planning during the initial stage of construction of traceability systems and during their operational phase.

Engineering Robustness of Microbial Cell Factories.

Gong, Zhiwei; Nielsen, Jens; Zhou, Yongjin J

2017-10-01

Metabolic engineering and synthetic biology offer great prospects in developing microbial cell factories capable of converting renewable feedstocks into fuels, chemicals, food ingredients, and pharmaceuticals. However, prohibitively low production rate and mass concentration remain the major hurdles in industrial processes even though the biosynthetic pathways are comprehensively optimized. These limitations are caused by a variety of factors unamenable for host cell survival, such as harsh industrial conditions, fermentation inhibitors from biomass hydrolysates, and toxic compounds including metabolic intermediates and valuable target products. Therefore, engineered microbes with robust phenotypes is essential for achieving higher yield and productivity. In this review, the recent advances in engineering robustness and tolerance of cell factories is described to cope with these issues and briefly introduce novel strategies with great potential to enhance the robustness of cell factories, including metabolic pathway balancing, transporter engineering, and adaptive laboratory evolution. This review also highlights the integration of advanced systems and synthetic biology principles toward engineering the harmony of overall cell function, more than the specific pathways or enzymes. © 2017 WILEY-VCH Verlag GmbH & Co.

A tau-charm-factory at Argonne

International Nuclear Information System (INIS)

Norem, J.; Repond, J.

1994-01-01

In this paper we explore the possibility of building a tau-charm-factory at the Argonne National Laboratory. A tau-charm-factory is an e + e - collider with a center-of-mass energy between 3.0 GeV and 5.0 GeV and a luminosity of at least 1 x 10 33 cm -2 s -1 . Once operational, the facility will produce large samples of τ pairs, charm mesons, and charmonium with either negligible or well understood backgrounds. This will lead to high precision measurements in the second generation quark and the third generation lepton sectors that cannot be done at other facilities. Basic physical properties and processes, such as the tau neutrino mass, rare tau decays, charm decay constants, rare charm meson decays, neutral D 0 -- meson mixing, and many more will be studied with unique precision. An initial design of the collider including the injector system is described. The design shows that a luminosity of at least 1 x 10 33 cm -2 s -1 can be achieved over the entire center-of-mass energy range of the factory

Neutrino beams from the decay of muons in a storage ring offer the prospect of very high flux, well-understood spectra, and equal numbers of electron and muon neutrinos, as desirable for detailed exploration of neutrino oscillations via long baseline detectors [1]. Such beams require. large numbers of muons, and hence a high performance target station at which a 1-4 MW proton beam of 16-24 GeV impinges on a compact target, all inside a high field solenoid channel to capture as much of the phase volume of soft pions as possible. A first concept was based on a carbon target, as reported in 2000 the Neutrino Factory Study-I [2]. A higher performance option based on a free mercury jet has been studied in 2001 as part of the Neutrino Factory Feasibility Study-II [3,4]. An overview of a mercury jet target facility is presented here, including requirements, design concept and summaries of simulated performance. Further details are presented in related papers at this conference

Muon Acceleration: Neutrino Factory and Beyond

Energy Technology Data Exchange (ETDEWEB)

Bogacz, Alex [Thomas Jefferson National Accelerator Facility (TJNAF), Newport News, VA (United States)

2018-03-01

We summarize the current state of a concept for muon acceleration aimed at a future Neutrino Factory and extendable to Higgs Factory. The main thrust of these studies was to reduce the overall cost while maintaining performance by exploring the interplay between the complexity of the cooling systems and the acceptance of the accelerator complex. To ensure adequate survival for the short-lived muons, acceleration must occur at high average gradient. The need for large transverse and longitudinal acceptances drives the design of the acceleration system to an initially low RF frequency, e.g., 325 MHz, which is then increased to 650 MHz as the transverse size shrinks with increasing energy. High-gradient normal conducting RF cavities at these frequencies require extremely high peak-power RF sources. Hence superconducting RF (SRF) cavities are chosen. We consider an SRF-efficient design based on a multi-pass (4.5) ?dogbone? RLA, extendable to multi-pass FFAG-like arcs.

The Physics of the B Factories

International Nuclear Information System (INIS)

Bevan, A.J.; Golob, B.; Mannel, T.

2014-01-01

The inspiration for this book came from Fran@cois le Diberder. During his term as spokesperson for BABAR he laid down a vision for the two B Factory detector collaborations, BABAR and Belle, to work together on a book that would describe the methodologies used and physics results obtained by those experiments. A key ideal emphasized from the outset was that this book should be written from a pedagogical perspective; it should be of interest to the student and expert alike. This vision was presented during a BABAR collaboration meeting on the island of Elba in May 2008 and a follow up Belle collaboration meeting at KEK, with visiting colleagues from the BABAR collaboration, and was embraced by the community. A number of workshops involving people from the theoretical community as well as the two collaborations were held on four continents over the following years. The resulting book, ''The Physics of the B Factories'', is a testament to the way that this concept captured the zeitgeist on both sides of the Pacific Ocean. This book is divided into three parts, the first of which provides a brief description of the B Factories, including a short (though not exhaustive) historical perspective, as well as descriptions of the detectors, ancillary data acquisition systems and data (re)processing systems that were built by the two detector collaborations in the late 1990's. The second part of the book discusses tools and methods that are frequently used when analyzing the data collected. These range from details of low level reconstruction algorithms and abstract summaries of statistical methods to high level prescriptions used when evaluating systematic uncertainties on measurements of observables. The third part of the book is devoted to physics results. This includes sufficient theoretical discussion in order for the reader to understand the context of the work being described. We are indebted to our colleagues from the theoretical community who have helped us achieve

The title overviews were compiled to support the market introduction campaign for solar water heaters in the Netherlands. Use has been made of the data-banks of the Dutch subsidy administrator 'Senter'. 88% of the 1,883 systems, that were installed in 1993, are solar water heaters. Considering the solar collector surface the largest contribution is from the use of mainly uncovered collectors in swimming pools: 51% (37% for the collector surface of solar water heaters). Energy utilities are involved in the installation of 70% of the solar heating systems (even 77% for the solar water heaters). Next to the quarterly overviews, the subsidy data for the period 1988 up to and including 1993 are analyzed. 70% of the installed systems has been purchased and 30% was rented. At the end of 1993 preparations were made to install more than 3,000 solar boilers in 1994 and 1995. 3 figs., 21 tabs

Data Management System at the Photon Factory Macromolecular Crystallography Beamline

2013-01-01

Macromolecular crystallography is a very powerful tool to investigate three-dimensional structures of macromolecules at the atomic level, and is widely spread among structural biology researchers. Due to recent upgrades of the macromolecular crystallography beamlines at the Photon Factory, beamline throughput has improved, allowing more experiments to be conducted during a user's beam time. Although the number of beamlines has increased, so has the number of beam time applications. Consequently, both the experimental data from users' experiments and data derived from beamline operations have dramatically increased, causing difficulties in organizing these diverse and large amounts of data for the beamline operation staff and users. To overcome this problem, we have developed a data management system by introducing commercial middleware, which consists of a controller, database, and web servers. We have prepared several database projects using this system. Each project is dedicated to a certain aspect such as experimental results, beam time applications, beam time schedule, or beamline operation reports. Then we designed a scheme to link all the database projects.

This report describes a research project to examine the hardware used in automated control systems like those that control the electric grid. This report provides an overview of the vendors, architectures, and supply channels for a number of control system devices. The research itself represents an attempt to probe more deeply into the area of programmable logic controllers (PLCs) - the specialized digital computers that control individual processes within supervisory control and data acquisition (SCADA) systems. The report (1) provides an overview of control system networks and PLC architecture, (2) furnishes profiles for the top eight vendors in the PLC industry, (3) discusses the communications protocols used in different industries, and (4) analyzes the hardware used in several PLC devices. As part of the project, several PLCs were disassembled to identify constituent components. That information will direct the next step of the research, which will greatly increase our understanding of PLC security in both the hardware and software areas. Such an understanding is vital for discerning the potential national security impact of security flaws in these devices, as well as for developing proactive countermeasures.

An analysis of a target factory leading to the determination of production expressions has provided for the basis of a parametric study. Parameters involving the input and output rate of a process system, processing yield factors, and multiple processing steps and production lines have been used to develop an understanding of their dependence on the rate of target injection for laser fusion. Preliminary results have indicated that a parametric study of this type will be important in the selection of processing methods to be used in the final production scheme of a target factory

Damped button electrode for B-Factory BPM system

Energy Technology Data Exchange (ETDEWEB)

Shintake, T; Akasaka, N; Obina, T; Chin, Y H [National Lab. for High Energy Physics, Tsukuba, Ibaraki (Japan)

1996-08-01

A new concept of damping of resonances in a button electrode has been proposed and tested in the BPM system for the B-Factory project at KEK (KEKB). Since a very high current beam has to be stored in the machine, even a small resonance in the ring will result in losing a beam due to multi-bunch instabilities. In a conventional button electrode used in BPMs, a TE110 mode resonance can be trapped in the gap between the electrode and the vacuum chamber. In order to damp this mode, the diameter of the electrode has been chosen to be small to increase the resonance frequency and to radiate the power into the beam pipe. In addition, an asymmetric structure is applied to extract the EM energy of the TE110 mode into the coaxial cable as the propagating TEM mode which has no cut-off frequency. Results of the computer simulations and tests with cold models are reported. The quality factor of the TE110 mode was small enough due to the radiation into the beam pipe even in the conventional electrode and the mode coupling effect due to the asymmetric shape was significant on a cavity-like TE111 mode.

The inspiration for this book came from Fran@cois le Diberder. During his term as spokesperson for BABAR he laid down a vision for the two B Factory detector collaborations, BABAR and Belle, to work together on a book that would describe the methodologies used and physics results obtained by those experiments. A key ideal emphasized from the outset was that this book should be written from a pedagogical perspective; it should be of interest to the student and expert alike. This vision was presented during a BABAR collaboration meeting on the island of Elba in May 2008 and a follow up Belle collaboration meeting at KEK, with visiting colleagues from the BABAR collaboration, and was embraced by the community. A number of workshops involving people from the theoretical community as well as the two collaborations were held on four continents over the following years. The resulting book, ''The Physics of the B Factories'', is a testament to the way that this concept captured the zeitgeist on both sides of the Pacific Ocean. This book is divided into three parts, the first of which provides a brief description of the B Factories, including a short (though not exhaustive) historical perspective, as well as descriptions of the detectors, ancillary data acquisition systems and data (re)processing systems that were built by the two detector collaborations in the late 1990's. The second part of the book discusses tools and methods that are frequently used when analyzing the data collected. These range from details of low level reconstruction algorithms and abstract summaries of statistical methods to high level prescriptions used when evaluating systematic uncertainties on measurements of observables. The third part of the book is devoted to physics results. This includes sufficient theoretical discussion in order for the reader to understand the context of the work being described. We are indebted to our colleagues from the theoretical community who

An asymmetric B factory based on PEP

International Nuclear Information System (INIS)

1991-02-01

In this report we describe a design for a high-luminosity Asymmetric B Factory to be built in the PEP tunnel on the SLAC site. This proposal, a collaborative effort SLAC, LBL, and LLNL, is the culmination of more than two years of effort aimed at the design and construction of an asymmetric e + e - collider capable of achieving a luminosity of L = 3 x 10 33 cm -2 s -1 . The configuration adopted utilizes two storage rings, and electron ring operating at 9 GeV and a positron ring at 3.1 GeV, each with a circumference of 2200 m. The high-energy ring is an upgrade of the PEP storage ring at SLAC; all PEP magnets and most power supplies will be reused. The upgrade consists primarily of replacing the PEP vacuum chamber and RF system with newly designed versions optimized for the high-current environment of the B Factory. The low-energy ring will be newly constructed and will be situated atop the high-energy ring in the PEP tunnel. Utilities already installed in the PEP tunnel are largely sufficient to operate the two B Factory storage rings

Energy usage in Beet Suger Factories. Sockerfabrikens energianvaendning; En systemstudie

Energy Technology Data Exchange (ETDEWEB)

Feltborg, G

1990-02-01

A computer program has been developed in order to simulate the energy consumption of beet sugar factories, for various plant configurations. The program is divided into five block units: Extraction and Juice purification, Juice concentration, Crystallization, Drying and finally the Power House. Each block consists of different modules, for example, a heat exchanger, an evaporator, a turbine and a dryer. The purpose of this project was to simulate some different system configurations of a sugar factory, whereby both new and previously used process technologies were utilized. The following parts of the process have been particularly emphasized: Power House - gas turbine, waste heat boiler. Drying - low-temperature dryer, steam dryer. Evaporation - vapour recompression. Crystallization - vapour recompression, continuous system. The different plant configurations have been compared to a reference factory, which is designed according to current technology used in a modern and well balanced Swedish factory. The comparisons are based upon the total power consumption as well as the total annual energy costs. Eleven different plant configurations were studied. The maximum power reduction is 36%, relative to the reference factory. The dissertation also contains an experimental study of a low-temperature drying process. The drying characteristics of pressed beet pulp were studied in a specially designed rotary dryer pilot plant. A number of parameters were varied i.e. the solid moisture content, air velocity, temperature and rotational speed. The results are given in terms of an apparent volumetric heat-transfer coefficient, determined from measured data. A mathematical model was established to determine the residence time of the material in the rotary dryer at different air velocities. (45 refs.).

2018-01-01

ExMC is creating an ecosystem of tools to enable well-informed medical system trade studies. The suite of tools address important system implementation aspects of the space medical capabilities trade space and are being built using knowledge from the medical community regarding the unique aspects of space flight. Two integrating models, a systems engineering model and a medical risk analysis model, tie the tools together to produce an integrated assessment of the medical system and its ability to achieve medical system target requirements. This presentation will provide an overview of the various tools that are a part of the tool ecosystem. Initially, the presentation's focus will address the tools that supply the foundational information to the ecosystem. Specifically, the talk will describe how information that describes how medicine will be practiced is captured and categorized for efficient utilization in the tool suite. For example, the talk will include capturing what conditions will be planned for in-mission treatment, planned medical activities (e.g., periodic physical exam), required medical capabilities (e.g., provide imaging), and options to implement the capabilities (e.g., an ultrasound device). Database storage and configuration management will also be discussed. The presentation will include an overview of how these information tools will be tied to parameters in a Systems Modeling Language (SysML) model, allowing traceability to system behavioral, structural, and requirements content. The discussion will also describe an HRP-led enhanced risk assessment model developed to provide quantitative insight into each capability's contribution to mission success. Key outputs from these various tools, to be shared with the space medical and exploration mission development communities, will be assessments of medical system implementation option satisfaction of requirements and per-capability contributions toward achieving requirements.

WQO is Decidable for Factorial Languages

KAUST Repository

Atminas, Aistis

2017-08-08

A language is factorial if it is closed under taking factors, i.e. contiguous subwords. Every factorial language can be described by an antidictionary, i.e. a minimal set of forbidden factors. We show that the problem of deciding whether a factorial language given by a finite antidictionary is well-quasi-ordered under the factor containment relation can be solved in polynomial time. We also discuss possible ways to extend our solution to permutations and graphs.

Baby factories taint surrogacy in Nigeria.

2016-01-01

The practice of reproductive medicine in Nigeria is facing new challenges with the proliferation of 'baby factories'. Baby factories are buildings, hospitals or orphanages that have been converted into places for young girls and women to give birth to children for sale on the black market, often to infertile couples, or into trafficking rings. This practice illegally provides outcomes (children) similar to surrogacy. While surrogacy has not been well accepted in this environment, the proliferation of baby factories further threatens its acceptance. The involvement of medical and allied health workers in the operation of baby factories raises ethical concerns. The lack of a properly defined legal framework and code of practice for surrogacy makes it difficult to prosecute baby factory owners, especially when they are health workers claiming to be providing services to clients. In this environment, surrogacy and other assisted reproductive techniques urgently require regulation in order to define when ethico-legal lines have been crossed in providing surrogacy or surrogacy-like services.

Haiti. Educating factory workers.

Science.gov (United States)

Hughes, H

1990-04-01

There are approximately 50,000 workers employed in the light assembly industry in Haiti. About 70% are women, the majority of whom are aged between 25 and 34 years, and are either single or in a nonpermanent relationship with the father of their children. Many live and work in appalling conditions, surviving on very low wages to support several children and an extended family. The acquired immunodeficiency syndrome (AIDS) is now a visible problem in many factories. In October 1988, the Center for the Promotion of Women Workers (Centre de Promotion des Femmes Ouvriers/CPFO) launched a pilot AIDS education program for factory women. The Center, based in a large industrial zone near the airport, runs a health clinic and courses in literacy, communications skills, health promotion and family planning. The new AIDS program allowed CPFO staff to gain entry into factories for the 1st time. Other courses were held outside working hours and outside factory premises. Staff contacted manages by telephone to arrange a meeting to discuss AIDS and to ask permission to hold educational "round tables" with workers. Of 18 managers in the factories approached over a 12-month period, only 2 refused entry to CPFO staff. Almost all managers reported they had registered between 2 and 5 deaths from AIDS among their employees over the past couple of years. A total of 85 educational sessions, each lasting about 2 hours, were held within 28 different factories, community or labor organizations reaching 3063 workers (male and female). In each session, the presentation was carried out by 2 CPFO trained monitors and included a slide show, flip charts, and the video "Met ko," originally produced for Haitian immigrants in New York. The most important aspect of the program was the training of 38 volunteer factory-based health promoters. These promoters attended the round table sessions, where they facilitated discussion and distributed condoms and were subsequently available for counseling co

The purpose of this report is to provide an overview of Micro-System technology as it applies to inertial sensing. Transduction methods are reviewed with capacitance and piezoresistive being the most often used in COTS Micro-electro-mechanical system (MEMS) inertial sensors. Optical transduction is the most recent transduction method having significant impact on improving sensor resolution. A few other methods are motioned which are in a R&D status to hopefully allow MEMS inertial sensors to become viable as a navigation grade sensor. The accelerometer, gyroscope and gravity gradiometer are the type of inertial sensors which are reviewed in this report. Their method of operation and a sampling of COTS sensors and grade are reviewed as well.

G-Cloud Monitor: A Cloud Monitoring System for Factory Automation for Sustainable Green Computing

Directory of Open Access Journals (Sweden)

Hwa-Young Jeong

2014-11-01

Full Text Available Green and cloud computing (G-cloud are new trends in all areas of computing. The G-cloud provides an efficient function, which enables users to access their programs, systems and platforms at anytime and anyplace. Green computing can also yield greener technology by reducing power consumption for sustainable environments. Furthermore, in order to apply user needs to the system development, the user characteristics are regarded as some of the most important factors to be considered in product industries. In this paper, we propose a cloud monitoring system to observe and manage the manufacturing system/factory automation for sustainable green computing. For monitoring systems, we utilized the resources in the G-cloud environments, and hence, it can reduce the amount of system resources and devices, such as system power and processes. In addition, we propose adding a user profile to the monitoring system in order to provide a user-friendly function. That is, this function allows system configurations to be automatically matched to the individual’s requirements, thus increasing efficiency.

METABOLIC MODELLING IN THE DEVELOPMENT OF CELL FACTORIES BY SYNTHETIC BIOLOGY

Directory of Open Access Journals (Sweden)

Paula Jouhten

2012-10-01

Full Text Available Cell factories are commonly microbial organisms utilized for bioconversion of renewable resources to bulk or high value chemicals. Introduction of novel production pathways in chassis strains is the core of the development of cell factories by synthetic biology. Synthetic biology aims to create novel biological functions and systems not found in nature by combining biology with engineering. The workflow of the development of novel cell factories with synthetic biology is ideally linear which will be attainable with the quantitative engineering approach, high-quality predictive models, and libraries of well-characterized parts. Different types of metabolic models, mathematical representations of metabolism and its components, enzymes and metabolites, are useful in particular phases of the synthetic biology workflow. In this minireview, the role of metabolic modelling in synthetic biology will be discussed with a review of current status of compatible methods and models for the in silico design and quantitative evaluation of a cell factory.

Comments on particle identification at the B factory

Ratcliff, B.N.

1992-01-01

The importance of particle identification at an asymmetric B Factory is discussed, and the general status of a number of particle identification technologies which might be included in B Factory detectors is briefly reviewed. It is generally agreed that high quality hadronic particle identification is fundamental to the central mission of understanding CP violation at the B Factory, but there is as yet no clear open-quotes consensusclose quotes solution for such a detector. In a sense, this lack of a particle identification solution is a matter of definition. There is, in fact, a perfectly reasonable, open-quotes conventional technologyclose quotes, particle identification system which makes use of a large tracking chamber with excellent (i.e., relativistic rise quality) dE/dx surrounded by a good TOF with a rather long flight path. The chamber must be rather large (around 2 meters in outer radius) and perhaps high pressure as well, but similar devices are rather well understood and it would appear to be possible to meet the particle identification performance required at B Factory momenta. This solution has not been embraced by any of the detector groups, however, because of the effect it has on the electromagnetic calorimetry. open-quotes Everyoneclose quotes wants high quality calorimetry (such as can be provided by CsI crystals), but such devices cost a great deal per unit volume, and the cost scales roughly like the inner radius squared. Moreover, no one wants to see the high quality (expensive) calorimetry compromised by excessive mass in front. Thus, the essence of the particle identification problem is that there is no approximately massless, very thin particle identification device known with adequate performance. Of course, it might equally well be said that there is no high quality calorimeter known which is sufficiently cost-effective to be placed outside an appropriately sized tracking plus particle identification system

International Nuclear Information System (INIS)

1997-12-01

The CADS database is a standardized, quality-assured, and configuration-controlled data management system developed to assist in the task of characterizing the DOE surplus HEU material. Characterization of the surplus HEU inventory includes identifying the specific material; gathering existing data about the inventory; defining the processing steps that may be necessary to prepare the material for transfer to a blending site; and, ultimately, developing a range of the preliminary cost estimates for those processing steps. Characterization focuses on producing commercial reactor fuel as the final step in material disposition. Based on the project analysis results, the final determination will be made as to the viability of the disposition path for each particular item of HEU. The purpose of this document is to provide an informational overview of the CADS database, its evolution, and its current capabilities. This document describes the purpose of CADS, the system requirements it fulfills, the database structure, and the operational guidelines of the system

Batteries used in photovoltaic applications are required to have particular properties in order to minimize the system cost, in addition to meeting stringent reliability requirements associated with PV system installations. The battery sizing, installations, operation and maintenance, thus, are fundamentally different from those used in several other energy storage applications. The current paper gives an overview of battery systems commonly used in PV installation, as well as several new options which are found suitable or have been modified suitably to meet PV energy storage requirements. The systems are discussed briefly with respect to their construction, performance characteristics and compatibility with PV systems. The battery sizing procedures are also reviewed. (Author).

Analysis of scaled-factorial-moment data

International Nuclear Information System (INIS)

Seibert, D.

1990-01-01

We discuss the two standard constructions used in the search for intermittency, the exclusive and inclusive scaled factorial moments. We propose the use of a new scaled factorial moment that reduces to the exclusive moment in the appropriate limit and is free of undesirable multiplicity correlations that are contained in the inclusive moment. We show that there are some similarities among most of the models that have been proposed to explain factorial-moment data, and that these similarities can be used to increase the efficiency of testing these models. We begin by calculating factorial moments from a simple independent-cluster model that assumes only approximate boost invariance of the cluster rapidity distribution and an approximate relation among the moments of the cluster multiplicity distribution. We find two scaling laws that are essentially model independent. The first scaling law relates the moments to each other with a simple formula, indicating that the different factorial moments are not independent. The second scaling law relates samples with different rapidity densities. We find evidence for much larger clusters in heavy-ion data than in light-ion data, indicating possible spatial intermittency in the heavy-ion events

In this report we describe a design for a high-luminosity Asymmetric B Factory to be built in the PEP tunnel on the SLAC site. This proposal, a collaborative effort SLAC, LBL, and LLNL, is the culmination of more than two years of effort aimed at the design and construction of an asymmetric e{sup +}e{sup {minus}} collider capable of achieving a luminosity of L = 3 {times} 10{sup 33} cm{sup {minus}2} s{sup {minus}1}. The configuration adopted utilizes two storage rings, and electron ring operating at 9 GeV and a positron ring at 3.1 GeV, each with a circumference of 2200 m. The high-energy ring is an upgrade of the PEP storage ring at SLAC; all PEP magnets and most power supplies will be reused. The upgrade consists primarily of replacing the PEP vacuum chamber and RF system with newly designed versions optimized for the high-current environment of the B Factory. The low-energy ring will be newly constructed and will be situated atop the high-energy ring in the PEP tunnel. Utilities already installed in the PEP tunnel are largely sufficient to operate the two B Factory storage rings.

The proposed B factory accelerator facilities will require active feedback systems to control multibunch instabilities. These feedback systems must operate in machines with thousands of circulating bunches and with short (2--4 ns) interbunch intervals. The functional requirements for transverse (betatron) and longitudinal (synchrotron) feedback systems are presented. Several possible implementation options are discussed and system requirements developed. Conceptual designs are presented for the PEP II transverse and longitudinal feedback systems

Factorials of real negative and imaginary numbers - A new perspective.

Presently, factorials of real negative numbers and imaginary numbers, except for zero and negative integers are interpolated using the Euler's gamma function. In the present paper, the concept of factorials has been generalised as applicable to real and imaginary numbers, and multifactorials. New functions based on Euler's factorial function have been proposed for the factorials of real negative and imaginary numbers. As per the present concept, the factorials of real negative numbers, are complex numbers. The factorials of real negative integers have their imaginary part equal to zero, thus are real numbers. Similarly, the factorials of imaginary numbers are complex numbers. The moduli of the complex factorials of real negative numbers, and imaginary numbers are equal to their respective real positive number factorials. Fractional factorials and multifactorials have been defined in a new perspective. The proposed concept has also been extended to Euler's gamma function for real negative numbers and imaginary numbers, and beta function.

The Low-Energy Neutrino Factory

To date most studies of Neutrino Factories have focused on facilities where the energy of the muon in the storage ring has been in the range of 25-50 GeV. In this paper we present a concept for a Low-Energy (∼ 4 GeV) neutrino factory. For baselines of O(1000 km), the rich oscillation pattern at low neutrino interaction energy (0.5 - ∼3 GeV) provides the unique performance of this facility with regard to its sensitivity to CP violation and the determination of the neutrino mass hierarchy. A unique neutrino detector is needed, however, in order to exploit this oscillation pattern. We will describe the basic accelerator facility, demonstrate the methodology of the analysis and give an estimate on how well the Low-Energy neutrino factory can measure θ 13 , CP violation and the mass hierarchy. We will also describe the detector concept that is used, show a preliminary analysis regarding its performance and indicate what R and D is still needed. Finally we will show how the Low-Energy neutrino factory could be a step towards an energy frontier muon collider.

The Energy Factory is a collaboration of 26 Dutch local water boards in which options for energy saving and energy production are examined. According to the authors, the initiative of the Energy Factory will lead to a reframing of the role of the water boards. Moreover, they explain how the PPP concept (People, Planet, Profit) may act as platform for negotiations between actors who are involved in the Energy Factory. In addition, the PPP concept is used to demonstrate that the Energy Factory will lead to larger social involvement, social entrepreneurship and growing profits [Dutch] De Energiefabriek is een samenwerkingsverband van 26 waterschappen in Nederland waarin wordt gezocht naar mogelijkheden om energie te besparen en zelf energie te produceren.

Daarnaast leggen ze uit hoe het PPP-concept (People, Profit, Planet) kan fungeren als platform voor onderhandelingen tussen de actoren die betrokken zijn bij de Energiefabriek. Verder wordt met het PPP-concept aangetoond dat de Energiefabriek leidt tot ruimere maatschappelijke betrokkenheid, maatschappelijk ondernemen en winstvergroting.

OSG has been operating for a few years at UCSD a glideinWMS factory for several scientific communities, including CMS analysis, HCC and GLOW. This setup worked fine, but it had become a single point of failure. OSG thus recently added another instance at Indiana University, serving the same user communities. Similarly, CMS has been operating a glidein factory dedicated to reprocessing activities at Fermilab, with similar results. Recently, CMS decided to host another glidein factory at CERN, to increase the availability of the system, both for analysis, MC and reprocessing jobs. Given the large overlap between this new factory and the three factories in the US, and given that CMS represents a significant fraction of glideins going through the OSG factories, CMS and OSG formed a common operations team that operates all of the above factories. The reasoning behind this arrangement is that most operational issues stem from Grid-related problems, and are very similar for all the factory instances. Solving a probl...

Full Text Available To manage the impact of Industry 4.0 on industrial engineering (IE education curriculum requirements, realistic teaching and learning infrastructure such as a learning factory are required. This paper scans the literature to determine Industry 4.0’s principles and interactions with IE and a learning factory, surveys relevant universities by questionnaire to determine its current status and practices, and formulates didactic design parameters for an Industry 4.0 learning factory to support IE education in South Africa, making use of existing models of cyber-physical systems and learning factory morphology. In other results, the technical universities are discovered to be more positively disposed, in general terms, to developing an Industry 4.0 learning factory than are the traditional programmes which, with one exception, prefer computational facilities. Of ten universities that offer IE, only one — a traditional programme — has made significant progress towards creating an Industry 4.0 learning factory.

Software factory techniques applied to process control at CERN

2008-01-01

The CERN Large Hadron Collider (LHC) requires constant monitoring and control of quantities of parameters to guarantee operational conditions. For this purpose, a methodology called UNICOS (UNIfied Industrial COntrols Systems) has been implemented to standardize the design of process control applications. To further accelerate the development of these applications, we migrated our existing UNICOS tooling suite toward a software factory in charge of assembling project, domain and technical information seamlessly into deployable PLC (Programmable logic Controller) - SCADA (Supervisory Control And Data Acquisition) systems. This software factory delivers consistently high quality by reducing human error and repetitive tasks, and adapts to user specifications in a cost-efficient way. Hence, this production tool is designed to encapsulate and hide the PLC and SCADA target platforms, enabling the experts to focus on the business model rather than specific syntaxes and grammars. Based on industry standard software, ...

The ultra high luminosity B-factory (SuperB) project of INFN requires a high performance and reliable injection system, providing electrons at 4 GeV and positrons at 7 GeV, to fulfil the very tight requirements of the collider. Due to the short beam lifetime, continuous injection of electron and positron bunches in both LER and HER rings is necessary to maintain an high average luminosity. Polarized electrons are required for experiments and must be delivered by the injection system, due to the beam lifetime shorter than the ring polarization build-up: they will be produced by means of a SLAC-SLC polarized gun. The emittance and the energy spread of the e{sup -}/e{sup +} beams are reduced in a 1 GeV Damping Ring (DR) before injection in the main rings. Two schemes for positron production are under study, one with e{sup -}/e{sup +} conversion at low energy (< 1 Gev) and one with conversion at 6 GeV and a recirculation line to bring the positrons back to the DR. Acceleration through the Linac is provided by a 2856 MHz RF system made of travelling wave (TW), room temperature accelerating structures.

Photon Factory Activity Report no.12 deals with our activities in the period from October 1993 through September 1994. We operate two light sources at the Photon Factory; the 2.5-GeV Photon Factory storage ring, which is a dedicated light source, and the 6.5-GeV TRISTAN Accumulation Ring, which is parasitically used as a light source. We keep more than seventy experimental stations at two facilities, and accept experiments primarily according to approval by the Program Advisory Committee. The number of proposals to the Photon Factory has been still growing. Three-hundred eighty two proposals were approved by the PAC in FY1994, which is an increase by thirteen percent compared to the previous year. Remarkable was growth in biology proposals, particularly proposals in protein crystallography. In FY 1994, we accepted approximately 20,000 man-days as general users, and almost ten percent of them were from abroad. We always open the facility to users, not only domestic but also international. Recently we have been concentrating our effort to upgrading of the light sources and reconstruction of the experimental stations to keep the Photon Factory an attractive research facility in the forthcoming years. We have already started a program of reducing the emittance of the 2.5-GeV storage ring, which now operates with an emittance of 110 nm-rad, to 27 nm-rad by modifying the lattice, with the goal of operation at the reduced emittance in the fall of 1997. We also have conceived of a conversion of the TRISTAN Accumulation Ring to a dedicated light source of high energies. The on-going TRISTAN project will terminate by the end of 1995, and the TRISTAN Main Ring will be converted to a new B-Factory. At this moment, the TRISTAN Accumulation Ring will be disused as the injector to the Main Ring, and conversion of the AR to a dedicated light source becomes possible. (J.P.N.)

Propionibacteria are actinobacteria consisting of two principal groups: cutaneous and dairy. Cutaneous propionibacteria are considered primary pathogens to humans, whereas dairy propionibacteria are widely used in the food and pharmaceutical industries. Increasing attention has been focused on improving the performance of dairy propionibacteria for the production of industrially important chemicals, and significant advances have been made through strain engineering and process optimization in the production of flavor compounds, nutraceuticals, and antimicrobial compounds. In addition, genome sequencing of several propionibacteria species has been completed, deepening understanding of the metabolic and physiological features of these organisms. However, the metabolic engineering of propionibacteria still faces several challenges owing to the lack of efficient genome manipulation tools and the existence of various types of strong restriction-modification systems. The emergence of systems and synthetic biology provides new opportunities to overcome these bottlenecks. In this review, we first introduce the major species of propionibacteria and their properties and provide an overview of their functions and applications. We then discuss advances in the genome sequencing and metabolic engineering of these bacteria. Finally, we discuss systems and synthetic biology approaches for engineering propionibacteria as efficient and robust cell factories for the production of industrially important chemicals.

With respect to a managing technology of advanced factories in the Japanese chemical industry, this paper enumerates the following three examples to discuss the ways the future factory technologies should be: operation techniques and problems in a newest ethylene plant, operation supports and facility control in chemical factories, and CIM structuring in beer breweries. The paper describes the operation techniques in an ethylene plant that are broken down into the following: measures for safety and material diversification, environment preservation, means to minimize the required labor, adoption of multi-variables, non-interference control technology for ethylene-propylene columns, and operation techniques that have been introduced with such a new technique as an integrated instrumentation room equipped with a gas leakage detection system. Structuring of CIM in the cited beer brewery has followed the transition of IE-TQC-JIT-FMS-CIM. Although a beer brewery may give somewhat different image from an ordinary chemical plant, the beer brewing process resembles a chemical plant in that it operates reacting machines in batch multiple tanks, and uses instrumentations and controllers using sensors. The key point in the future development is an organic link between market fluctuation and production activities. 1 fig.

Particular emphasis is placed on the description of the technological process of wastewater treatment at the ‘Natron-Hayat’ Maglaj factory which is represented in the paper by a technological scheme and represents one of the more complex systems for wastewater treatment. In the experimental part, the results of the efficiency of the wastewater treatment system at the ‘Natron-Hayat’ Maglaj factory were given. It can be said that the basic raw materials for paper production are cellulose fibers and water. The role that water has in the cellulose and paper industry as the solvent, agent for cooking and washing of the produced pulp, indicates the presence of water in almost all stages of cellulose fiber production (Žarković et al., 2004. In accordance with the principles of sustainable development, cellulose and paper industry must face strict regulations on the protection of the environment which includes rationalization of raw material consumption, water, energy and chemicals, with ‘Natron-Hayat’ Maglaj are subjected to the purification before discharging into surface water recipient. The wastewaters from ‘Natron-Hayat’ Maglaj factory are discharged into river Bosna.

Biogas - a contribution to the solution of the problem of energy supply for cheese factories

Energy Technology Data Exchange (ETDEWEB)

Favre, R; Bachmann, M

1985-01-01

During a two years period the energy consumption of four different cheese factories has been analysed. The whey of the four cheese factories is used for fattening pigs in an attached piggery. All four factories are equipped with biogas-digesters which use the slurry from the piggeries for methane production. The overall energy consumption per ton of milk transformed varies from 600 and 885 MJ. This includes the energy used for heating the fermentation rooms and the cheese maker's flat as well as the energy used for the piggery. 10 to 40% of the total energy is being consumed in form of electricity. Three of the four digesters are working at temperatures of 30 to 35/sup 0/C. One is run in the psychrophilic range, i.e. without heating system. The heated systems use 20 to 40% of the total gas production for heating the digesters. The net gas production of all four systems is of the same order of magnitude. The necessary energy for milk transformation depends on the type of installation used and on the skill of the cheese maker to use his installation economically. Between 30 and 60% of the total energy demand of the four factories has been covered by biogas. Economic problems regarding the use of biogas in cheese factories are discussed.

The authors describe the drivers of the current energy debate and the state of the art in making factories energy efficient. They explain important principles that must be observed in considering factories as a system and in order to understand questions relating to energy. They have developed methods for finding appropriate energy-efficient solutions in factory planning. Detailed explanations are given on energy-relevant installations which require planning such as drives, compressed air systems or ventilation systems. The book presents methods and instruments for the analysis and evaluation of energy consumption which can be used for assessment purposes during the initial planning as well as for monitoring and influencing energy consumption during normal operation. Selected practical examples, notably from the automotive industry, serve to illustrate the material presented. The book is intended primarily for planning and production engineers in the piece goods industry as well as for students in related fields.

Quantum mechanics paradoxes at the Φ-factory

International Nuclear Information System (INIS)

Ghirardi, G.C.; Grassi, R.; Weber, T.

1991-04-01

We discuss the possibility of performing experiments allowing one to test quantum mechanics versus any local realistic model within the context of the physics at the Φ-factory. After having sketched the main features of the physical process under consideration and having focused the locality requirements for it, we derive Bell's inequality for the two-meson system. Comparison with quantum predictions shows that the inequality is not violated for any choice of the parameters characterizing the measurement process. Contrary to the case of spin variables, there is then no way to exclude, by experiments at the Φ-factory, the possibility of a local realistic description of the process. A recent suggestion about a test of quantum predictions versus the assumption of a spontaneous factorization mechanism, as well as the claimed validity of an inequality which is different from Bell's one, are also discussed. The general conclusion is that the Φ-factory facility does not seem to open new ways of testing quantum mechanics versus alternative general schemes of the type which are usually regarded as worth considering the debate about locality and quantum mechanics. The concluding Section is devoted to making clear our position with respect to the problems discussed in this paper. It is pointed out that, in our opinion, the existing experimental evidence makes already clear that one has to accept the ''mysterious'' features of microscopic systems. The really crucial problem is that of investigating whether one can restore a coherent worldview which generally conforms with our experience at the macroscopic level, by keeping all highly successful predictions of quantum theory at the microscopic one.

at factories characterized by low planning maturity, but lower for factories with medium planning maturity. For low planning maturity, the APS module is used for improving the configuration of the manufacturing system, whereas high planning maturity is required to capture performance benefits from optimization......Through a study of four embedded action research cases within a global OEM, it is investigated how the frequency of use and contribution of an Advanced Planning and Scheduling (APS) module are affected by factory context. The performance contribution of the APS module is found to be high...... and scenario planning. Further, it is found that planning complexity at the factory increases both the frequency of use and the contribution of using APS modules. On the basis of the findings, three propositions are formulated on the link between factory context and the use of APS module....

Systems Factorial Technology provides new insights on global-local information processing in autism spectrum disorders.

Science.gov (United States)

Johnson, Shannon A; Blaha, Leslie M; Houpt, Joseph W; Townsend, James T

2010-02-01

Previous studies of global-local processing in autism spectrum disorders (ASDs) have indicated mixed findings, with some evidence of a local processing bias, or preference for detail-level information, and other results suggesting typical global advantage, or preference for the whole or gestalt. Findings resulting from this paradigm have been used to argue for or against a detail focused processing bias in ASDs, and thus have important theoretical implications. We applied Systems Factorial Technology, and the associated Double Factorial Paradigm (both defined in the text), to examine information processing characteristics during a divided attention global-local task in high-functioning individuals with an ASD and typically developing controls. Group data revealed global advantage for both groups, contrary to some current theories of ASDs. Information processing models applied to each participant revealed that task performance, although showing no differences at the group level, was supported by different cognitive mechanisms in ASD participants compared to controls. All control participants demonstrated inhibitory parallel processing and the majority demonstrated a minimum-time stopping rule. In contrast, ASD participants showed exhaustive parallel processing with mild facilitatory interactions between global and local information. Thus our results indicate fundamental differences in the stopping rules and channel dependencies in individuals with an ASD.

Feasibility of testing local hidden variable theories in a Charm factory

It is commonly believed that the local hidden variable theories (LHVTs) can be tested through measuring the Bell inequalities. This scheme, for the massive particle system, was originally set up for the entangled K 0 K 0 pair system from the φ factory. In this paper we show that the J/Ψ→K 0 K 0 process is even more realistic for this goal. We analyze the unique properties of J/Ψ in the detection of basic quantum effects, and find that it is possible to use J/Ψ decay as a test of LHVTs in the future τ-charm factory. Our analyses and conclusions are generally also true for other heavy onium decays

Pump testing - Comparison of factory vs. field test of centrifugal pumps

International Nuclear Information System (INIS)

Fehlau, R.

1992-01-01

Testing of pumps in situ, i.e., as installed in a system, will typically yield somewhat different performance results from the original manufacturer's factory test. This paper discusses some of the reasons for these variations. It shows that the factory test curves can be used for evaluation of initial acceptance tests but not for reference in normal inservice testing (IST). This is the basis for reference values used in American Society of Mechanical Engineers (ASME) Section 11 specifications and the revised ASME Code 1990

Survivor shielding. Part A. Nagasaki factory worker shielding

Santoro, Robert T.; Barnes, John M.; Azmy, Yousry Y.; Kerr, George D.; Egbert, Stephen D.; Cullings, Harry M.

Recent investigations based on conventional chromosome aberration data by the RERF suggest that the DS86 doses received by many Nagasaki factory workers may have been overestimated by as much as 40% relative to those for other survivors in Japanese-type houses and other shielding configurations (Kodama et al. 2001). Since the factory workers represent about 25% of the Nagasaki survivors with DS86 doses in excess of 0.5 Gy (50 rad), systematic errors in their dose estimates can have a major impact on the risk coefficients from RERF studies. The factory worker doses may have been overestimated for a number of reasons. The calculation techniques, including the factory building modeling, weapon source spectra and cross-section data used in the DS86 shielding calculations were not detailed enough to replicate actual conditions. The models used did not take into account local shielding provided by machinery, tools, and the internal structure in the buildings. In addition, changes in the disposition of shielding following collapse of the building by the blast wave were not considered. The location of large factory complexes may be uncertain, causing large numbers of factory survivors, correctly located relative to each other, to be uniformly too close to the hypocenter. Any or all of these reasons are sufficient to result in an overestimate of the factory worker doses. During the DS02 studies, factory worker doses have been reassessed by more carefully modeling the factory buildings, incorporating improved radiation transport methods and cross-section data and using the most recent bomb leakage spectra (Chapter 2). Two-dimensional discrete ordinates calculations were carried out initially to estimate the effects of workbenches and tools on worker doses to determine if the inclusion of these components would, in fact, reduce the dose by amounts consistent with the RERF observations (Kodama et al. 2001).

Design of a Low Cost Smart Dryer Temperature Measurement System for Tea Factories

Directory of Open Access Journals (Sweden)

Utpal SARMA

2009-09-01

Full Text Available This paper presents the design of a low cost smart dryer temperature measurement system for Tea Factories using K-type Thermocouple implementing linearization polynomial. The thermo emf is amplified by an instrumentation amplifier having high CMRR (106 dB and high input impedance (1012 Ohm. The analog signal is converted to digital form with the help of an SPI compatible 12-bit ADC. Data acquisition and transmission is done with an 8- bit microcontroller. As the dependence of thermo emf on temperature is not linear hence it is fitted with a polynomial. NIST data for K-type TC is taken as a standard for this fitting. The error with linear fit and polynomial fit is also presented. The digital data is corrected according to the polynomial and sent to a PC located at a remote control room for monitoring and data logging via RS232C communication. The performance of the entire system is discussed in the paper.

In Depth Diagnostics for RF System Operation in the PEP-II B Factory

International Nuclear Information System (INIS)

Van Winkle, Daniel; Fox, John; Teytelman, Dmitry; SLAC

2005-01-01

The PEP-II RF systems incorporate numerous feedback loops in the low-level processing for impedance control and operating point regulation. The interaction of the multiple loops with the beam is complicated, and the systems incorporate online diagnostic tools to configure the feedback loops as well as to record fault files in the case of an RF abort. Rapid and consistent analysis of the RF-related beam aborts and other failures is critical to the reliable operation of the B-Factory, especially at the recently achieved high beam currents. Procedures and algorithms used to extract diagnostic information from time domain fault files are presented and illustrated via example interpretations of PEP-II fault file data. Example faults presented will highlight the subtle interpretation required to determine the root cause. Some such examples are: abort kicker firing asynchronously, klystron and cavity arcs, beam loss leading to longitudinal instability, tuner read back jumps and poorly configured low-level RF feedback loop

Full Text Available Bangladesh is a developing country and has a lot of factories for different products for local use and also export to abroad. Garments industries are one of the top most items of exported items. A huge number of populations are working in garments industries. But these factories are not well designed in sense of the thermal environment. Workers experiences sickness related to indoor environment. The productions of these factories are affected due to employees’ health condition. The research is done in two different methods. One is empirical data collection using thermal data loggers and the other is questionnaire survey on the spots for three factory buildings. The field study was conducted in four different months of the same year during winter and summer period. Expected findings of this research are that the indoor environment is not comfortable for works at day time during summer season. This research will help the factory workers in providing a comfortable thermal environment and also help the employers or factory owners to increase their production margin.

Software factory techniques applied to Process Control at CERN

CERN Multimedia

Dutour, MD

2007-01-01

The CERN Large Hadron Collider (LHC) requires constant monitoring and control of quantities of parameters to guarantee operational conditions. For this purpose, a methodology called UNICOS (UNIfied Industrial COntrols Systems) has been implemented to standardize the design of process control applications. To further accelerate the development of these applications, we migrated our existing UNICOS tooling suite toward a software factory in charge of assembling project, domain and technical information seamlessly into deployable PLC (Programmable logic Controller) – SCADA (Supervisory Control And Data Acquisition) systems. This software factory delivers consistently high quality by reducing human error and repetitive tasks, and adapts to user specifications in a cost-efficient way. Hence, this production tool is designed to encapsulate and hide the PLC and SCADA target platforms, enabling the experts to focus on the business model rather than specific syntaxes and grammars. Based on industry standard software...

Particle identification at an asymmetric B Factory

Coyle, P.; Eigen, G.; Hitlin, D.; Oddone, P.; Ratcliff, B.; Roe, N.; Va'vra, J.; Ypsilantis, T.

1991-09-01

Particle identification systems are an important component of any detector at a high-luminosity, asymmetric B Factory. In particular, excellent hadron identification is required to probe CP violation in B 0 decays to CP eigenstates. The particle identification systems discussed below also provide help in separating leptons from hadrons at low momenta. We begin this chapter with a discussion of the physics motivation for providing particle identification, the inherent limitations due to interactions and decays in flight, and the requirements for hermiticity and angular coverage. A special feature of an asymmetric B Factory is the resulting asymmetry in the momentum distribution as a function of polar angle; this will also be quantified and discussed. In the next section the three primary candidates, time-of-flight (TOF), energy loss (dE/dx), and Cerenkov counters, both ring-imaging and threshold, will be briefly described and evaluated. Following this, one of the candidates, a long-drift Cerenkov ring-imaging device, is described in detail to provide a reference design. Design considerations for a fast RICH are then described. A detailed discussion of aerogel threshold counter designs and associated R ampersand D conclude the chapter. 56 refs., 64 figs., 13 tabs

Mathematical modeling of biological processes provides deep insights into complex cellular systems. While quantitative and continuous models such as differential equations have been widely used, their use is obstructed in systems wherein the knowledge of mechanistic details and kinetic parameters is scarce. On the other hand, a wealth of molecular level qualitative data on individual components and interactions can be obtained from the experimental literature and high-throughput technologies, making qualitative approaches such as Boolean network modeling extremely useful. In this paper, we build on our research to provide a methodology overview of Boolean modeling in systems biology, including Boolean dynamic modeling of cellular networks, attractor analysis of Boolean dynamic models, as well as inferring biological regulatory mechanisms from high-throughput data using Boolean models. We finally demonstrate how Boolean models can be applied to perform the structural analysis of cellular networks. This overview aims to acquaint life science researchers with the basic steps of Boolean modeling and its applications in several areas of systems biology. (paper)

Craddock, M.K.; Baartman, R.; Burge, R.

1988-06-01

The TRIUMF KAON Factory proposal has made considerable progress on both technical and political fronts over the last year. A racetrack-shaped lattice is now being considered in conjunction with a three-element slow extraction system in an effort to reduce losses to the 0.1% level. Hardware studies have continued on both magnet power supplies and on rf cavities - the latter work gaining an extra dimension from a recently-instituted formal collaboration with LAMPF. The H - extraction system for the cyclotron has been tested successfully with 66 μA pulsed and 10 μA average beams. On the political side, British Columbia has agreed to fund the buildings and tunnels (Cdn dollar 87M) and is making the KAON Factory its top priority project with the Canadian federal government. A joint federal-provincial delegation has traveled abroad and found that a number of countries would consider significant contributions to the cost. Approval of dollar 11 million in pre-construction R and D funds is expected imminently, permitting formal negotiations to start abroad, with final approval for construction coming in 1989

The benefits and challenges of sharing glidein factory operations across nine time zones between OSG and CMS

OSG has been operating for a few years at UCSD a glideinWMS factory for several scientific communities, including CMS analysis, HCC and GLOW. This setup worked fine, but it had become a single point of failure. OSG thus recently added another instance at Indiana University, serving the same user communities. Similarly, CMS has been operating a glidein factory dedicated to reprocessing activities at Fermilab, with similar results. Recently, CMS decided to host another glidein factory at CERN, to increase the availability of the system, both for analysis, MC and reprocessing jobs. Given the large overlap between this new factory and the three factories in the US, and given that CMS represents a significant fraction of glideins going through the OSG factories, CMS and OSG formed a common operations team that operates all of the above factories. The reasoning behind this arrangement is that most operational issues stem from Grid-related problems, and are very similar for all the factory instances. Solving a problem in one instance thus very often solves the problem for all of them. This paper presents the operational experience of how we address both the social and technical issues of running multiple instances of a glideinWMS factory with operations staff spanning multiple time zones on two continents.

BASIC OVERVIEW ABOUT DIGITAL FACTORY AND VIRTUAL COMMISSIONING

Directory of Open Access Journals (Sweden)

Radko Popovič

2015-03-01

Full Text Available The paper deals with PLM systems, which are using for management of products during their lifetime. For that it is necessary to have some special tool for it. Especially if we want to handle pre-production phase. The main philosophy is to get fully functional virtual system before it will be created in real production. This virtual system needs to be modeled according to requirements of product and its process of production. This concept is called virtual commissioning. Environment, which contains machines, robots, equipment, workers and products, needs to be simulated with all possible scenarios before it will be implemented to real production. The resolution of this idea is not only cost saving, but also shorter time of production planning.

Systems for carbon trading. An overview

International Nuclear Information System (INIS)

Hasselknippe, Henrik

2003-12-01

This paper focuses on the increasing number of regional, national and international systems for trading and transfer of greenhouse gas emission allowances and emission reduction credits. The paper will serve as a platform for further discussions on the development of the international carbon trading market. The analysis builds on the International Emissions Trading Association (IETA) Trading Schemes Database, which has been developed by Point Carbon, covering all known trading schemes and programs. A full overview of all existing trading schemes and proposals is presented, showing inter alia the outreach and judicial nature of the systems, the range and nature of emission reduction or credit purchase targets, allocation methods used, links to external systems, and possibilities for the use of project-based credits. A comparative assessment is performed on a number of design criteria, allowing for conclusions to be drawn on the level of harmonisation of these systems, and the identification of convergence or divergence of important operational features. The systems covered in the analysis display considerable variation when it comes to key design criteria and functionality. A rapid integration of many of the planned and active systems seems likely following the agreement on the EU emissions trading scheme, and will be further accelerated if the Kyoto Protocol is ratified

2014-12-01

Full Text Available This paper, by referring to the archaeological reports and local gazetteers and comparing images of porcelain wares, makes a comprehensive and in-depth analysis of the layout of power and space in Jingdezhen Imperial Factory according to its geography, geomancy, security management, space regulation, architectural features, production characteristics and production layout. It contends that the Imperial Factory which integrates porcelain making factory with local government is the embodiment of absolute monarchy in ceramic culture. The factory is located on Zhushan mountain, the center of Jingdezhen’s industry, business and transportation. Being at the center, it gives off an air of prestige and majesty, overlooking dominantly the surrounding private kilns. It has also turned the political system into power operation, setting up not only workshops but also administrative offices. By taking advantage of the best resources, it has produced porcelain for imperial family and court. Its specialized production has solved the contradiction between complicated technology and numerous procedures of production. The shape, color and pattern of the porcelain wares are strictly stipulated and the best of the best wares are demanded. Hence the porcelain production is featured with longest firing, largest scale, superb craftsmanship, and best kinds of wares. All of these reveal the process and rule power and space are intersected and different cultures overlapped.

Factorial experiments have rarely been used in the development or evaluation of clinical interventions. However, factorial designs offer advantages over randomized controlled trial designs, the latter being much more frequently used in such research. Factorial designs are highly efficient (permitting evaluation of multiple intervention components with good statistical power) and present the opportunity to detect interactions amongst intervention components. Such advantages have led methodologists to advocate for the greater use of factorial designs in research on clinical interventions (Collins, Dziak, & Li, 2009). However, researchers considering the use of such designs in clinical research face a series of choices that have consequential implications for the interpretability and value of the experimental results. These choices include: whether to use a factorial design, selection of the number and type of factors to include, how to address the compatibility of the different factors included, whether and how to avoid confounds between the type and number of interventions a participant receives, and how to interpret interactions. The use of factorial designs in clinical intervention research poses choices that differ from those typically considered in randomized clinical trial designs. However, the great information yield of the former encourages clinical researchers' increased and careful execution of such designs. Copyright © 2017. Published by Elsevier Ltd.

Battery Management System Hardware Concepts: An Overview

Directory of Open Access Journals (Sweden)

Markus Lelie

2018-03-01

Full Text Available This paper focuses on the hardware aspects of battery management systems (BMS for electric vehicle and stationary applications. The purpose is giving an overview on existing concepts in state-of-the-art systems and enabling the reader to estimate what has to be considered when designing a BMS for a given application. After a short analysis of general requirements, several possible topologies for battery packs and their consequences for the BMS’ complexity are examined. Four battery packs that were taken from commercially available electric vehicles are shown as examples. Later, implementation aspects regarding measurement of needed physical variables (voltage, current, temperature, etc. are discussed, as well as balancing issues and strategies. Finally, safety considerations and reliability aspects are investigated.

In several years, technologies and systems based on the Internet of things (IoT) will be widely used in all smart factories. When processing a huge array of unstructured data, their filtration and adequate interpretation are a priority for enterprises. In this context, the correct representation of information in a user-friendly form acquires special importance, for which the market today presents advanced analytical platforms designed to collect, store and analyze data on technological processes and events in real time. The main idea of the paper is the statement of the information security problem in IoT and integrity of processed information.

Factorial correlators: angular scaling within QCD jets

International Nuclear Information System (INIS)

Peschanski, R.

2001-01-01

Factorial correlators measure the amount of dynamical correlation in the multiplicity between two separated phase-space windows. We present the analytical derivation of factorial correlators for a QCD jet described at the double logarithmic (DL) accuracy. We obtain a new angular scaling property for properly normalized correlators between two solid-angle cells or two rings around the jet axis. Normalized QCD factorial correlators scale with the angular distance and are independent of the window size. Scaling violations are expected beyond the DL approximation, in particular from the subject structure. Experimental tests are feasible, and thus would be welcome. (orig.)

In this paper an overview on the NSSS fluid system design of PGSFR is described based on the issued design documents. System concepts and major components design concepts for PHTS, IHTS, DHRS and SWRPRS were developed. Thermal-hydraulic characteristics were analyzed based on CFD simulation. The design bases and concepts for auxiliary systems were also developed. The upstream design requirements of fluid system such as system design requirements, component design requirements, I and C design requirements, BOP interface design requirements, design guides and P and IDs were produced. The control logic and computer code for the analysis for operational characteristics is under progress. The protection system consists of a safety grade PPS and a non-safety grade DPS (Diverse Protection System). The DPS provides a diverse method to trip the reactor to satisfy the requirements relative to ATWS (Anticipated Transients Without Scram) as well as Defense-In-Depth and Diversity.

Fontana, Juan; Lopez-Iglesias, Carmen; Tzeng, Wen-Ping; Frey, Teryl K.; Fernandez, Jose J.; Risco, Cristina

Viral factories are complex structures in the infected cell where viruses compartmentalize their life cycle. Rubella virus (RUBV) assembles factories by recruitment of rough endoplasmic reticulum (RER), mitochondria and Golgi around modified lysosomes known as cytopathic vacuoles or CPVs. These organelles contain active replication complexes that transfer replicated RNA to assembly sites in Golgi membranes. We have studied the structure of RUBV factory in three dimensions by electron tomography and freeze-fracture. CPVs contain stacked membranes, rigid sheets, small vesicles and large vacuoles. These membranes are interconnected and in communication with the endocytic pathway since they incorporate endocytosed BSA-gold. RER and CPVs are coupled through protein bridges and closely apposed membranes. Golgi vesicles attach to the CPVs but no tight contacts with mitochondria were detected. Immunogold labelling confirmed that the mitochondrial protein p32 is an abundant component around and inside CPVs where it could play important roles in factory activities.

Calibration of the beam-position monitor system for the SLAC PEP-II B factory

International Nuclear Information System (INIS)

Johnson, R.; Smith, S.; Kurita, N.

1997-06-01

The Beam-Position Monitors (BPM) for the PEP-II B Factory consist of four 1.5-cm diameter button style pickups mounted on the diagonals of the quadrupole vacuum chambers. Before installation of the vacuum chambers in the quadrupole assemblies, the electrical center of the BPMs is measured with respect to the mechanical center in a calibration test stand. In this paper the calibration test stand is described and the precision and accuracy of the calibrations are presented. After installation of the quadrupole assemblies in the PEP-II tunnel, the passive attenuation for each channel of the system is measured to preserve the accuracy of the calibration. Finally, the active electronics includes an onboard calibrator. Results for these portions of the calibration are presented

Optimization of a furniture factory layout

Directory of Open Access Journals (Sweden)

Tadej Kanduč

2015-03-01

Full Text Available This paper deals with the problem of optimizing a factory floor layout in a Slovenian furniture factory. First, the current state of the manufacturing system is analyzed by constructing a discrete event simulation (DES model that reflects the manufacturing processes. The company produces over 10,000 different products, and their manufacturing processes include approximately 30,000 subprocesses. Therefore, manually constructing a model to include every subprocess is not feasible. To overcome this problem, a method for automated model construction was developed to construct a DES model based on a selection of manufacturing orders and relevant subprocesses. The obtained simulation model provided insight into the manufacturing processes and enable easy modification of model parameters for optimizing the manufacturing processes. Finally, the optimization problem was solved: the total distance the products had to traverse between machines was minimized by devising an optimal machine layout. With the introduction of certain simplifications, the problem was best described as a quadratic assignment problem. A novel heuristic method based on force-directed graph drawing algorithms was developed. Optimizing the floor layout resulted in a significant reduction of total travel distance for the products.

Rogers, C T; Prior, G; Gilardoni, S; Neuffer, D; Snopok, P; Alekou, A; Pasternak, J

2013-01-01

In the neutrino factory, muons are produced by firing high-energy protons onto a target to produce pions. The pions decay to muons and pass through a capture channel known as the muon front end, before acceleration to 12.6 GeV. The muon front end comprises a variable frequency rf system for longitudinal capture and an ionization cooling channel. In this paper we detail recent improvements in the design of the muon front end.

SWITCH: a dynamic CRISPR tool for genome engineering and metabolic pathway control for cell factory construction in Saccharomyces cerevisiae.

Science.gov (United States)

Vanegas, Katherina García; Lehka, Beata Joanna; Mortensen, Uffe Hasbro

2017-02-08

The yeast Saccharomyces cerevisiae is increasingly used as a cell factory. However, cell factory construction time is a major obstacle towards using yeast for bio-production. Hence, tools to speed up cell factory construction are desirable. In this study, we have developed a new Cas9/dCas9 based system, SWITCH, which allows Saccharomyces cerevisiae strains to iteratively alternate between a genetic engineering state and a pathway control state. Since Cas9 induced recombination events are crucial for SWITCH efficiency, we first developed a technique TAPE, which we have successfully used to address protospacer efficiency. As proof of concept of the use of SWITCH in cell factory construction, we have exploited the genetic engineering state of a SWITCH strain to insert the five genes necessary for naringenin production. Next, the naringenin cell factory was switched to the pathway control state where production was optimized by downregulating an essential gene TSC13, hence, reducing formation of a byproduct. We have successfully integrated two CRISPR tools, one for genetic engineering and one for pathway control, into one system and successfully used it for cell factory construction.

DEVELOPMENT OF LAW RELATING TO FACTORIES IN INDIA

Directory of Open Access Journals (Sweden)

M. K. Sahu

2015-01-01

Full Text Available The rapid growth of industrial town and factories has paved the way to develop our industrial legislation accordingly. The Government of India never expressed their interest in framing separate legislation vis-à-vis factories which resulted in implementation of the same statute which was enacted pre-independence. It was done by virtue of Art. 372 of the Constitution of India. However, the Constitutional Lawmakers created vacuum for the implementation of new statute in accordance with the demand of society by inserting scope under the Directive Principles of State Policies. However, in the 67 years history of Indian Republic, there are unprecedented developments of law relating to factories in India.The Government of India, with the adoption of existed statute, made an effort to incorporate the welfare legislation but it never developed along with the change in time. It is to be noticed that as far as existing statutes are concerned, the development is an effect of judicial pronouncement or some tragic incident like Bhopal Gas Tragedy. This paper succinctly describes the history of factory legislation, the constitutional validity of the previous statute and necessary amendment which have already been done and / or on the verge of being amended. It will further discuss contribution of judiciary in developing the law relating to factories, scope of industrial jurisprudence in promoting the development of factory legislation. The primary focus of the research project is to reflect upon the areas where factory legislation has developed, so that proper yardstick could be made in order to put emphasis on those areas which have been remained untouched.

There are two principles which the management of a research institute like KEK must respect when dealing with such big project as B-Factory. One is the scientific merit of the project and the other is the organizational consideration which includes financial, human, technical and historical elements. Ideally, the two principles are to be fully taken into account. But, in many cases, one or the other is only partially fulfilled due to unavoidable circumstances. The lack of flexibility to respond to all possible situations is more dangerous and may lead to a disaster as in the case of SSC. I will describe the process which lead to the successful construction, operation and physics presentations of KEK B-Factory following faithfully the official records.

The research on the utilization of emitted light has conspicuously developed recently, and also in Japan, the National Laboratory for High Energy Physics planned the construction of the 2.5 GeV Photon Factory and completed it as the facility commonly utilized by researchers in various fields. Hitachi Ltd. designed and manufactured the deflecting electromagnets, quadrupole electromagnets and their exciting power sources installed in the storage ring emitting light, and the electromagnets for the transport line from an electron linear accelerator to the storage ring. Since high uniformity and high accuracy are required for the spatial distribution of magnetic field intensity of respective electromagnets, the accuracy of finishing magnetic pole surfaces was made within +-0.02 mm, and the accuracy of assembling and the absolute values of pole gaps were made within +-0.05 mm, thus the expected performance was able to be attained. Besides, as to the stabilized power sources, transistor control system was adopted for those of both deflecting electromagnets and quadrupole electromagnets, and the stability of 5 x 10 -4 and 1 x 10 -5 or less respectively was able to be attained. In this paper, the technical matters of electromagnets and power sources are reported. (Kako, I.)

With the advent of the deep economic crisis in Argentina on 2001, the recovery of companies through to the creation of the Cooperatives Working Self-Management or Factories Recovered by its workers was constituted as one of the ways in which the salaried disobeyed the increasing unemployment. When the companies turn into recovered factories they tend to leave of side practices that have been seen like imposed by the previous organization and not understanding them as a primary condition for the execution of his tasks. Safety and ergonomics are two disciplines that are no longer considered relevant to the daily work. Therefore this investigation aims to revalue, undergo semantic to give back to a place in every organization analyzed. This research developed a self-diagnostic tool for working conditions, and the environment, present in the recovered factories.

2015-01-01

There is no doubt today about the possibilities and potential of digital impression-taking with the aid of intraoral optical impression systems, and the past few years have seen a considerable increase in the range of optical intraoral scanners available on the market. On the strength of numerous innovations and a wider range of indications in orthodontics and implantology, intraoral scanning systems appear to be a highly promising development for the future. Digital impression-taking with intraoral scanners has already shown itself in some respects to be clearly superior to conventional impression- taking. Particularly worthy of mention is the versatile integration of digital impressions into diagnostic and treatment concepts to provide a customizable healthcare solution for the patient. It remains exciting to look forward to future developments that will allow us to observe digital impression-taking--as with other digital applications already established in everyday life--becoming firmly established in the routine of dentistry and dental technology. This article presents an overview of the benefits and limitations of digital impression-taking using intraoral scanning systems, and includes a summary of all the relevant intraoral scanners available on the market at present.

In this paper, we present an overview of the System Design Analysis carried on for SHARK-NIR, the coronagraphic camera designed to take advantage of the outstanding performance that can be obtained with the FLAO facility at the LBT, in the near infrared regime. Born as a fast-track project, the system now foresees both coronagraphic direct imaging and spectroscopic observing mode, together with a first order wavefront correction tool. The analysis we here report includes several trade-offs for the selection of the baseline design, in terms of optical and mechanical engineering, and the choice of the coronagraphic techniques to be implemented, to satisfy both the main scientific drivers and the technical requirements set at the level of the telescope. Further care has been taken on the possible exploitation of the synergy with other LBT instrumentation, like LBTI. A set of system specifications is then flown down from the upper level requirements to finally ensure the fulfillment of the science drivers. The preliminary performance budgets are presented, both in terms of the main optical planes stability and of the image quality, including the contributions of the main error sources in different observing modes.

Full Text Available The article considered the influence of the heat consumers distribution and the flashing vapours effect juice for multipleevaporator sugar factory on the consumption the main production flow of heat transfer agent – water vapor. The problem of rational distribution of heat transfer agent for of the corps multiple-evaporator is relevant from point of view of energy saving and energysaving heat of the sugar factory. The solution to this problem is advantageously carried out on the basis of quantitative mathematical description of the distribution of vapor on the corps of the evaporation plant. The heat consumers distribution should be based on technical and economic calculation. To solve this problem it is advisable to use a single equation that determines the dependence of the steam flow in the first unit evaporator on the amount of evaporated water and the method of heat consumers distribution for housing. Evaporators sugar factory has two functions – technology and heat, each of which is described by its equation. On the basis of the material and heat balance equations for the realization of the basic functions of the system evaporator written multipleevaporator equations. The solution of this system allows you to obtain the equation of the steam flow and the amount of evaporated water, taking into account the flashing vapours effect. Solution of the system should take into account the accepted design standards of sugar factories. As a result of solving the system of equation is obtained, which allows you to organize and optimize the heat consumers distribution of the corps evaporator. The equation can be used for any number of units evaporator. This equation allows you to assess the efficiency of the evaporation plant of a sugar factory. This is of great practical importance in the modernization of thermal schemes of sugar factories.

Craddock, M.K.

1989-09-01

Proposals for high intensity proton synchrotrons (typically providing 100 μA (6 x 10 14 p/s)) at 30 GeV have been made in Canada, Europe, Japan, the USA and the USSR. These beams would be roughly 100 times more intense than those available now and would yield equivalent increases in the fluxes of secondary particles (kaons, pions, muons, antiprotons, hyperons and neutrinos) - or cleaner beams for a smaller increase in flux. The ability to investigate rare processes on the precision frontier opens new avenues to fundamental questions in both particle and nuclear physics, complementary to traditional approaches via the energy frontier. The demand for higher currents has led to novel features in many of the accelerator designs: asymmetric magnet cycles, avoidance of transition crossing, separate collector and stretcher rings, three-dimensional beam painting at injection, bucket-to-bucket beam transfer, perpendicular biassing of microwave ferrite in the rf tuners, the use of Siberian Snakes to preserve polarization, and the addition of a pre-septum to make slow extraction >99.8% efficient. Other characteristic features include rapid cycling rates, booster stages, H - injection, low impedance enclosures, powerful feedback systems for control of beam instabilities and beam loading, and local collimation systems for handling beam loss. This paper reviews the general features of kaon factory accelerator design and the status of the various proposals

2007-01-01

Italy produces approximately 4,520,000 tons of pasta annually, which is about 67% of its total productive potential. As factories need electric and thermal energy simultaneously, combined heat and power (CHP) systems are the most suitable. This paper describes a feasibility study of a CHP plant in a pasta factory in Italy while analyzing energy saving and environmental benefits. Commercially available CHP systems suitable for the power range of energy demand in pasta production use reciprocating engines or gas turbines. This study demonstrates how their use can reduce both energy costs and CO 2 equivalent greenhouse gas emission in the environment. An economic analysis was performed following the methodology set out by Italian National Agency for Technology, Energy and Environment (ENEA) based on a discounted cash flow (DCF) method called 'Valore Attuale Netto' (VAN), which uses a cash flow based on the saving of energy when using different energy processes

Full Text Available The rehabilitation works carried out in the Sennar sugarcane factory in Sudan, improved the rates of milling accompanied by the horizontal and vertical expansions of the farm compelled Sennar factory to go for mechanical harvesting to solve the problem of labor shortage. The aim of this paper is to evaluate the current sugarcane manual and mechanical harvesting systems with regard to production efficiency, cost effectiveness, cane loading efficiency, infield losses, and the effect of trash (extraneous matter in factory process. Different experiments were conducted to compare and contrast between the two harvesting systems. The results revealed that manual harvesting (8.98 SDG/ton is more expensive than mechanical harvesting (4.9.5 SDG/ton; the wages for the cane cutting labor represent 74.14% of the total cutting cost, 46% of the total manual harvesting cost, and 18.9% of the total harvesting cost. Infield cane losses represent 4.72% and 4.22% of the actual yield for the manual harvesting and mechanical harvesting systems, respectively. Moreover, the results showed a significant difference between the two harvesting systems with regard to the cane weight/trailer (ton/trailer and trash percent. On average the cane weight (ton/trailer is 6.88 for manual harvesting and 10.12 for mechanical harvesting. The trash percent is only 3.66% for manually harvested cane while it reached 9.49 for the mechanically harvested cane. A 1% increase in trash will lead to decrease in sugar recovery by 0.1%. It could recommended that Sennar Sugar Factory as well as other sugar factories in Sudan could go for increasing the mechanical harvesting system and reducing the manual harvesting to less than 10% of the total area. The specialized cane cutter labors should be employed in other agricultural operations during the off-season to insure their availability at the start of the season. A further research is needed to reduce the infield cane losses and trash percent

Pilot infrastructures are becoming prominent players in the Grid environment. One of the major advantages is represented by the reduced effort required by the user communities (also known as Virtual Organizations or VOs) due to the outsourcing of the Grid interfacing services, i.e. the pilot factory, to Grid experts. One such pilot factory, based on the glideinWMS pilot infrastructure, is being operated by the Open Science Grid at University of California San Diego (UCSD). This pilot factory is serving multiple VOs from several scientific domains. Currently the three major clients are the analysis operations of the HEP experiment CMS, the community VO HCC, which serves mostly math, biology and computer science users, and the structural biology VO NEBioGrid. The UCSD glidein factory allows the served VOs to use Grid resources distributed over 150 sites in North and South America, in Europe, and in Asia. This paper presents the steps taken to create a production quality pilot factory, together with the challenges encountered along the road.

Growing market turbulences and shorter product life cycles require a continuous adaptation of factory structures resulting in a continuous factory planning process. Therefore a new framework is developed which focuses on configuration and data management process integration. This enable an online system performance evaluation based on continuous availability of current data. The use of this framework is especially helpful and will guarantee high cost and time savings, when used in the early stages of the planning, called the concept or rough planning phase. The new framework is supported by a planning round table as a tool for team-based configuration processes integrating the knowledge of all persons involved in planning processes. A case study conducted at a German company shows the advantages which can be achieved by implementing the new framework and methods.

Work has begun on the merger of two well known systems, VEOS (HITLab) and CLIPS (NASA). In the recent past, the University of Massachusetts Lowell developed a parallel version of NASA CLIPS, called P-CLIPS. This modification allows users to create smaller expert systems which are able to communicate with each other to jointly solve problems. With the merger of a VEOS message system, PCLIPS-V can now act as a group of entities working within VEOS. To display the 3D virtual world we have been using a graphics package called HOOPS, from Ithaca Software. The artificial reality environment we have set up contains actors and objects as found in our Lincoln Logs Factory of the Future project. The environment allows us to view and control the objects within the virtual world. All communication between the separate CLIPS expert systems is done through VEOS. A graphical renderer generates camera views on X-Windows devices; Head Mounted Devices are not required. This allows more people to make use of this technology. We are experimenting with different types of virtual vehicles to give the user a sense that he or she is actually moving around inside the factory looking ahead through windows and virtual monitors.

An Overview of Liquid Fluoride Salt Heat Transport Systems

Energy Technology Data Exchange (ETDEWEB)

Holcomb, David Eugene [ORNL; Cetiner, Sacit M [ORNL

2010-09-01

Heat transport is central to all thermal-based forms of electricity generation. The ever increasing demand for higher thermal efficiency necessitates power generation cycles transitioning to progressively higher temperatures. Similarly, the desire to provide direct thermal coupling between heat sources and higher temperature chemical processes provides the underlying incentive to move toward higher temperature heat transfer loops. As the system temperature rises, the available materials and technology choices become progressively more limited. Superficially, fluoride salts at {approx}700 C resemble water at room temperature being optically transparent and having similar heat capacity, roughly three times the viscosity, and about twice the density. Fluoride salts are a leading candidate heat-transport material at high temperatures. Fluoride salts have been extensively used in specialized industrial processes for decades, yet they have not entered widespread deployment for general heat transport purposes. This report does not provide an exhaustive screening of potential heat transfer media and other high temperature liquids such as alkali metal carbonate eutectics or chloride salts may have economic or technological advantages. A particular advantage of fluoride salts is that the technology for their use is relatively mature as they were extensively studied during the 1940s-1970s as part of the U.S. Atomic Energy Commission's program to develop molten salt reactors (MSRs). However, the instrumentation, components, and practices for use of fluoride salts are not yet developed sufficiently for commercial implementation. This report provides an overview of the current understanding of the technologies involved in liquid salt heat transport (LSHT) along with providing references to the more detailed primary information resources. Much of the information presented here derives from the earlier MSR program. However, technology has evolved over the intervening years

Design, analysis and presentation of factorial randomised controlled trials

Directory of Open Access Journals (Sweden)

Little Paul

2003-11-01

Full Text Available Abstract Background The evaluation of more than one intervention in the same randomised controlled trial can be achieved using a parallel group design. However this requires increased sample size and can be inefficient, especially if there is also interest in considering combinations of the interventions. An alternative may be a factorial trial, where for two interventions participants are allocated to receive neither intervention, one or the other, or both. Factorial trials require special considerations, however, particularly at the design and analysis stages. Discussion Using a 2 × 2 factorial trial as an example, we present a number of issues that should be considered when planning a factorial trial. The main design issue is that of sample size. Factorial trials are most often powered to detect the main effects of interventions, since adequate power to detect plausible interactions requires greatly increased sample sizes. The main analytical issues relate to the investigation of main effects and the interaction between the interventions in appropriate regression models. Presentation of results should reflect the analytical strategy with an emphasis on the principal research questions. We also give an example of how baseline and follow-up data should be presented. Lastly, we discuss the implications of the design, analytical and presentational issues covered. Summary Difficulties in interpreting the results of factorial trials if an influential interaction is observed is the cost of the potential for efficient, simultaneous consideration of two or more interventions. Factorial trials can in principle be designed to have adequate power to detect realistic interactions, and in any case they are the only design that allows such effects to be investigated.

Beyond doubt, the advent of a kaon factory will be of immense significance for the study of hadronic atoms. Here we will discuss some classes of experiments that certainly can and will be done at a kaon factory, as well as some very interesting possibilities which deserve investigation. Among the certains we include the observation of hadronic x rays from kaonic and μ - atoms, for both Z greater than one and for the isotopes of hydrogen, mainly for strong interaction information. More conjectural is the possibility of measuring Xi - and Ω - x rays

2001-03-01

This document gives an overview of the European Activation System (EASY) as released in 2001. EASY-2001 consists of a wide range of codes, data and documentation all aimed at satisfying the objective of calculating the response of materials irradiated in a neutron flux. It is designed to investigate fusion devices that will act as intense sources of high energy (14 MeV) neutrons and cause significant activation of the surrounding materials. However, the very general nature of the calculational method and the data libraries means that it is applicable (with some reservations) to all situations (e.g. fission reactors or neutron sources) where materials are exposed to neutrons below 20 MeV

The Experience Factory: Strategy and Practice

Basili, Victor R.; Caldiera, Gianluigi

The quality movement, that has had in recent years a dramatic impact on all industrial sectors, has recently reached the system and software industry. Although some concepts of quality management, originally developed for other product types, can be applied to software, its specificity as a product which is developed and not produced requires a special approach. This paper introduces a quality paradigm specifically tailored on the problem of the systems and software industry. Reuse of products, processes and experiences originating from the system life cycle is seen today as a feasible solution to the problem of developing higher quality systems at a lower cost. In fact, quality improvement is very often achieved by defining and developing an appropriate set of strategic capabilities and core competencies to support them. A strategic capability is, in this context, a corporate goal defined by the business position of the organization and implemented by key business processes. Strategic capabilities are supported by core competencies, which are aggregate technologies tailored to the specific needs of the organization in performing the needed business processes. Core competencies are non-transitional, have a consistent evolution, and are typically fueled by multiple technologies. Their selection and development requires commitment, investment and leadership. The paradigm introduced in this paper for developing core competencies is the Quality Improvement Paradigm which consists of six steps: (1) Characterize the environment, (2) Set the goals, (3) Choose the process, (4) Execute the process, (5) Analyze the process data, and (6) Package experience. The process must be supported by a goal oriented approach to measurement and control, and an organizational infrastructure, called Experience Factory. The Experience Factory is a logical and physical organization distinct from the project organizations it supports. Its goal is development and support of core competencies

The objective of the present work is safe management of residues from Factory of Barren Ores, their reprocessing, expenditures reduction for remediation of Istiklol city former uranium tailings. For this purpose, some experiences were adopted - Factory of Barren Ores tailing use for filling up the open pit where water with uranium content 3-5 mg/l is located. Factory of Barren Ores waste are passed through heap leaching and have some amount of uranium salts dissolved in water. Thus, we propose to dissolve uranium from Factory of Barren Ores wastes with uranium bearing water flowing out from gallery and filling up the open-pit by radioactive wastes. In so doing, uranium content flowing out from gallery will increase twice, and further, passing them through apricot's shell, as a sorbent, we will clean the water against radionuclides. Residue samples with uranium content 0,015% from Factory of Barren Ores and uranium bearing waters from gallery 1 with uranium content 0,0025 g/l were used for laboratory tests. After which, a slurry was prepared by means of residue mixing with water in ratio of solid and liquid phases (S:L) - 1:2 and 9,7 ml of sulfuric acid (Ρ=1,82) was added which corresponds consumption by H 2 SO 4 176,54 kg/t. For the first test, leaching was carried out during 4 hours at ph=1,6 at room temperature. For the second test, leaching was carried out at 60 d eg C a nd ph=1,6 during 4 hours. Slurry heating and mixing was carried out by means of magnetic mixer. The basic residue leaching indicators are provided in this article.

Wheat (Triticum aestivum L.) is one of the most important agricultural crops in both space such as Bioregenerative Life Support Systems (BLSS) and urban agriculture fields, and its cultivation is affected by several environmental factors. The objective of this study was to investigate the influences of different environmental conditions (BLSS, plant factory, green house and field) on the wheat growth, thousand kernel weight (TKW), harvest index (HI), biomass yield and quality during their life cycle. The results showed that plant height partially influenced by the interaction effects with environment, and this influence decreased gradually with the plant development. It was found that there was no significant difference between the BLSS and plant factory treatments on yields per square, but the yield of green house and field treatments were both lower. TKW and HI in BLSS and plant factory were larger than those in the green house and field. However, grain protein concentration can be inversely correlated with grain yield. Grain protein concentrations decreased under elevate CO2 condition and the magnitude of the reductions depended on the prevailing environmental condition. Conditional interaction effects with environment also influenced the components of straw during the mature stage. It indicated that CO2 enriched environment to some extent was better for inedible biomass degradation and had a significant effect on "source-sink flow" at grain filling stage, which was more beneficial to recycle substances in the processes of the environment regeneration.

Phenomenology of neutrino oscillations at the neutrino factory

International Nuclear Information System (INIS)

Tang, Jian

2011-01-01

We consider the prospects for a neutrino factory measuring mixing angles, the CP violating phase and mass-squared differences by detecting wrong-charge muons arising from the chain μ + → ν e → ν μ → μ - and the right-charge muons coming from the chain μ + → anti ν μ → anti ν μ → μ - (similar to μ - chains), where ν e → ν μ and anti ν μ → anti ν μ are neutrino oscillation channels through a long baseline. First, we study physics with near detectors and consider the treatment of systematic errors including cross section errors, flux errors, and background uncertainties. We illustrate for which measurements near detectors are required, discuss how many are needed, and what the role of the flux monitoring is. We demonstrate that near detectors are mandatory for the leading atmospheric parameter measurements if the neutrino factory has only one baseline, whereas systematic errors partially cancel if the neutrino factory complex includes the magic baseline. Second, we perform the baseline and energy optimization of the neutrino factory including the latest simulation results from the magnetized iron neutrino detector (MIND). We also consider the impact of τ decays, generated by appearance channels ν μ → ν τ and ν e → ν τ , on the discovery reaches of the mass orderings, the leptonic CP violation, and the non-zero θ 13 , which we find to be negligible for the considered detector. Third, we make a comparison of a high energy neutrino factory to a low energy neutrino factory and find that they are just two versions of the same experiment optimized for different regions of the parameter space. In addition, we briefly comment on whether it is useful to build the bi-magic baseline at the low energy neutrino factory. Finally, the effects of one additional massive sterile neutrino are discussed in the context of a combined short and long baseline setup. It is found that near detectors can provide the required sensitivity at the

The approach to thermal equilibrium, or thermalization, in isolated quantum systems is among the most fundamental problems in statistical physics. Recent theoretical studies have revealed that thermalization in isolated quantum systems has several remarkable features, which emerge from quantum entanglement and are quite distinct from those in classical systems. Experimentally, well isolated and highly controllable ultracold quantum gases offer an ideal testbed to study the nonequilibrium dynamics in isolated quantum systems, promoting intensive recent theoretical endeavors on this fundamental subject. Besides thermalization, many isolated quantum systems show intriguing behavior in relaxation processes, especially prethermalization. Prethermalization occurs when there is a clear separation of relevant time scales and has several different physical origins depending on individual systems. In this review, we overview theoretical approaches to the problems of thermalization and prethermalization.

Hazardous factories: Nigerian evidence.

Science.gov (United States)

Oloyede, Olajide

2005-06-01

The past 15 years have seen an increasing governmental and corporate concern for the environment worldwide. For governments, information about the environmental performance of the industrial sector is required to inform macro-level decisions about environmental targets such as those required to meet UN directives. However, in many African, Asian, and Latin American countries, researching and reporting company environmental performance is limited. This article serves as a contribution to filling the gap by presenting evidence of physical and chemical risk in Nigerian factories. One hundred and three factories with a total of 5,021 workers were studied. One hundred and twenty physical and chemical hazards were identified and the result shows a high number of workers exposed to such hazards. The study also reveals that workers' awareness level of chemical hazards was high. Yet the danger was perceived in behavioral terms, especially by manufacturing firms, which tend to see environmental investment in an increasingly global economy as detrimental to profitability.

Technological improvements in accelerator design in the 1960's resulted in the capability to develop medium-energy proton accelerators with beam intensities of almost 1 mA. These beams are able to produce fluxes of secondary particles, including pions, muons, neutrinos, and neutrons, which are as much as 10,000 times as intense as those previously available. Those machines built for optimum meson production are commonly called meson factories. The characteristics of these facilities are reviewed, and the present programs in applied research, and some potential areas of future work are discussed

Byung Do Chung

2018-04-01

Full Text Available Interest in smart factories and smart supply chains has been increasing, and researchers have emphasized the importance and the effects of advanced technologies such as 3D printers, the Internet of Things, and cloud services. This paper considers an innovation in dynamic supply-chain design and operations: connected smart factories that share interchangeable processes through a cloud-based system for personalized production. In the system, customers are able to upload a product design file, an optimal supply chain design and operations plan are then determined based on the available resources in the network of smart factories. The concept of smart supply chains is discussed and six types of flexibilities are identified, namely: design flexibility, product flexibility, process flexibility, supply chain flexibility, collaboration flexibility, and strategic flexibility. Focusing on supply chain flexibility, a general planning framework and various optimization models for dynamic supply chain design and operations plan are proposed. Further, numerical experiments are conducted to analyze fixed, production, and transportation costs for various scenarios. The results demonstrate the extent of the dynamic supply chain design and operations problem, and the large variation in transportation cost.

The eldercare factory.

Rapid advances in service robotics together with dramatic shifts in population demographics have led to the notion that technology may be the answer to our eldercare problems. Robots are being developed for feeding, washing, lifting, carrying and mobilising the elderly as well as monitoring their health. They are also being proposed as a substitute for companionship. While these technologies could accrue major benefits for society and empower the elderly, we must balance their use with the ethical costs. These include a potential reduction in human contact, increased feeling of objectification and loss of control, loss of privacy and personal freedom as well as deception and infantilisation. With appropriate guidelines in place before the introduction of robots en masse into the care system, robots could improve the lives of the elderly, reducing their dependence and creating more opportunities for social interaction. Without forethought, the elderly may find themselves in a barren world of machines, a world of automated care: a factory for the elderly. Copyright © 2011 S. Karger AG, Basel.

Toxic metals such as lead and cadmium are among the pollutants that are created by the metal production factories and disseminated in the nature. In order to study the quantity of cadmium pollution in the environment of the metal production factories, 50 saplings of the spruce species at the peripheries of the metal production factories were examined and the samples of the leaves, roots, and stems of saplings planted around the factory and the soil of the environment of the factory were studied to investigate pollution with cadmium. They were compared to the soil and saplings of the spruce trees planted outside the factory as observer region. The results showed that the quantity of pollution in the leaves, stems, and roots of the trees planted inside the factory environment were estimated at 1.1, 1.5, and 2.5 mg/kg, respectively, and this indicated a significant difference with the observer region (p metal production factory was estimated at 6.8 mg/kg in the depth of 0-10 cm beneath the level of the soil. The length of roots in the saplings planted around the factory of metal production stood at 11 and 14.5 cm in the observer region which had a significant difference with the observer region (p production processes in the factory. © The Author(s) 2013.

Computer systems pervade every aspect of the DIII-D National Fusion Research program. This includes real-time systems acquiring experimental data from data acquisition hardware; cpu server systems performing short term and long term data analysis; desktop activities such as word processing, spreadsheets, and scientific paper publication; and systems providing mechanisms for remote collaboration. The DIII-D network ties all of these systems together and connects to the ESNET wide area network. This paper will give an overview of these systems, including their purposes and functionality and how they connect to other systems. Computer systems include seven different types of UNIX systems (HP-UX, REALIX, SunOS, Solaris, Digital UNIX, Ultrix, and IRIX), OpenVMS systems (both BAX and Alpha), MACintosh, Windows 95, and more recently Windows NT systems. Most of the network internally is ethernet with some use of FDDI. A T3 link connects to ESNET and thus to the Internet. Recent upgrades to the network have notably improved its efficiency, but the demand for bandwidth is ever increasing. By means of software and mechanisms still in development, computer systems at remote sites are playing an increasing role both in accessing and analyzing data and even participating in certain controlling aspects for the experiment. The advent of audio/video over the interest is now presenting a new means for remote sites to participate in the DIII-D program

Transcription factories are nuclear domains where gene transcription takes place although the molecular basis for their formation and maintenance are unknown. In this study, we explored how the properties of chromatin as a polymer may contribute to the structure of transcription factories. We found that transcriptional active chromatin contains modifications like histone H4 acetylated at Lysine 16 (H4K16ac). Single fibre analysis showed that this modification spans the entire body of the gene. Furthermore, H4K16ac genes cluster in regions up to 500 Kb alternating active and inactive chromatin. The introduction of H4K16ac in chromatin induces stiffness in the chromatin fibre. The result of this change in flexibility is that chromatin could behave like a multi-block copolymer with repetitions of stiff-flexible (active-inactive chromatin) components. Copolymers with such structure self-organize through spontaneous phase separation into microdomains. Consistent with such model H4K16ac chromatin form foci that associates with nascent transcripts. We propose that transcription factories are the result of the spontaneous concentration of H4K16ac chromatin that are in proximity, mainly in cis

Full Text Available Background: Incense and joss stick are generally used in the world. Most products were made in small household factories. There are many environmental and occupational hazards in these factories. Objective: To evaluate the workplace environmental and occupational hazards in small household incense and joss stick factories in Roi-Et, Thailand. Methods: Nine small household factories in rural areas of Roi-Et, Thailand, were studied. Dust concentration and small aerosol particles were counted through real time exposure monitoring. The inductively coupled plasma optical emission spectrometry (ICP-OES was used for quantitative measurement of heavy metal residue in incense products. Results: Several heavy metals were found in dissolved dye and joss sticks. Those included barium, manganese, and lead. Rolling and shaking processes produced the highest concentration of dust and aerosols. Only 3.9 % of female workers used personal protection equipment. Conclusion: Dust and chemicals were major threats in small household incense and joss stick factories in Thailand. Increasing awareness towards using personal protection equipment and emphasis on elimination of environmental workplace hazards should be considered to help the workers of this industry.

We demonstrate that near detectors are mandatory for the leading atmospheric parameter measurements if the neutrino factory has only one baseline, whereas systematic errors partially cancel if the neutrino factory complex includes the magic baseline. Second, we perform the baseline and energy optimization of the neutrino factory including the latest simulation results from the magnetized iron neutrino detector (MIND). We also consider the impact of {tau} decays, generated by appearance channels {nu}{sub {mu}} {yields} {nu}{sub {tau}} and {nu}{sub e} {yields} {nu}{sub {tau}}, on the discovery reaches of the mass orderings, the leptonic CP violation, and the non-zero {theta}{sub 13}, which we find to be negligible for the considered detector. Third, we make a comparison of a high energy neutrino factory to a low energy neutrino factory and find that they are just two versions of the same experiment optimized for different regions of the parameter space. In addition, we briefly comment on whether it is useful to build the bi-magic baseline at the low energy neutrino factory. Finally, the

We are now developing automated sample exchange robots for high-throughput protein crystallographic experiments for onsite use at synchrotron beam lines. It is part of the fully automated robotics systems being developed at the Photon Factory, for the purposes of protein crystallization, monitoring crystal growth, harvesting and freezing crystals, mounting the crystals inside a hutch and for data collection. We have already installed the sample exchange robots based on the SSRL automated mounting system at our insertion device beam lines BL-5A and AR-NW12A at the Photon Factory. In order to reduce the time required for sample exchange further, a prototype of a double-tonged system was developed. As a result of preliminary experiments with double-tonged robots, the sample exchange time was successfully reduced from 70 seconds to 10 seconds with the exception of the time required for pre-cooling and warming up the tongs

2013-01-01

Faced with competition Patrick Philippon - Les Defis du CEA no.179 - April 2013 from the emerging countries, the competitiveness of the industrialised nations depends on the ability of their industries to innovate. This strategy necessarily entails the reorganisation and optimisation of the production systems. This is the whole challenge for 'advanced manufacturing', which relies on the new information and communication technologies. Interactive robotics, virtual reality and non-destructive testing are all technological building blocks developed by CEA, now approved within a cross-cutting programme, to meet the needs of industry and together build the factories of tomorrow.

DeStaebler, H.

1990-07-01

The goal of the project is to observe CP violation in the bar BB system. This machine is supposed to be a factory for high energy physics, not an R ampersand D project for accelerator physics. There are a number of interrelated design issues arising from the different desires of the detector and the machine, some of which are listed in this paper. A number of background and beampipe issues are mentioned. The emphasis is on calculations. Any satisfactory design will combine measurements on existing machines with calculations pertaining to the measurement conditions as well as to the proposed machine. 57 refs

RIKEN RI Beam Factory project

Energy Technology Data Exchange (ETDEWEB)

Yano, Yasushige; Goto, Akira; Katayama, Takeshi [Institute of Physical and Chemical Research, Wako, Saitama (Japan)

1997-03-01

The RARF proposes `RIKEN RI Beam Factory` as a next facility-expanding project. The factory makes it the primary aim to provide RI (Radioactive Isotope) beams covering over the whole atomic-mass range with the world-highest intensity in a wide energy range up to several hundreds MeV/nucleon. These RI beams are generated by the fragmentation of high-intensity heavy-ion beams. For the efficient production heavy-ion energies will be boosted up to over 100 MeV/nucleon even for very heavy ions by a K2500-MeV superconducting ring cyclotron serving as a post accelerator of the existing K540-MeV ring cyclotron. A new type of experimental installation called `MUSES` (Multi-USe Experimental Storage rings) will be constructed as well. With MUSES, various types of unique colliding experiments will become possible. (author)

Background Delivery arrangements include changes in who receives care and when, who provides care, the working conditions of those who provide care, coordination of care amongst different providers, where care is provided, the use of information and communication technology to deliver care, and quality and safety systems. How services are delivered can have impacts on the effectiveness, efficiency and equity of health systems. This broad overview of the findings of systematic reviews can help policymakers and other stakeholders identify strategies for addressing problems and improve the delivery of services. Objectives To provide an overview of the available evidence from up-to-date systematic reviews about the effects of delivery arrangements for health systems in low-income countries. Secondary objectives include identifying needs and priorities for future evaluations and systematic reviews on delivery arrangements and informing refinements of the framework for delivery arrangements outlined in the review. Methods We searched Health Systems Evidence in November 2010 and PDQ-Evidence up to 17 December 2016 for systematic reviews. We did not apply any date, language or publication status limitations in the searches. We included well-conducted systematic reviews of studies that assessed the effects of delivery arrangements on patient outcomes (health and health behaviours), the quality or utilisation of healthcare services, resource use, healthcare provider outcomes (such as sick leave), or social outcomes (such as poverty or employment) and that were published after April 2005. We excluded reviews with limitations important enough to compromise the reliability of the findings. Two overview authors independently screened reviews, extracted data, and assessed the certainty of evidence using GRADE. We prepared SUPPORT Summaries for eligible reviews, including key messages, 'Summary of findings' tables (using GRADE to assess the certainty of the evidence), and

They describe more a what-to-do approach for validation, whereas the GAMP Suppliers Guide describes a how-to-do validation. Nevertheless, they do not contain major discrepancies.

Manufacturing data analytics using a virtual factory representation.

Science.gov (United States)

Jain, Sanjay; Shao, Guodong; Shin, Seung-Jun

2017-01-01

Large manufacturers have been using simulation to support decision-making for design and production. However, with the advancement of technologies and the emergence of big data, simulation can be utilised to perform and support data analytics for associated performance gains. This requires not only significant model development expertise, but also huge data collection and analysis efforts. This paper presents an approach within the frameworks of Design Science Research Methodology and prototyping to address the challenge of increasing the use of modelling, simulation and data analytics in manufacturing via reduction of the development effort. The use of manufacturing simulation models is presented as data analytics applications themselves and for supporting other data analytics applications by serving as data generators and as a tool for validation. The virtual factory concept is presented as the vehicle for manufacturing modelling and simulation. Virtual factory goes beyond traditional simulation models of factories to include multi-resolution modelling capabilities and thus allowing analysis at varying levels of detail. A path is proposed for implementation of the virtual factory concept that builds on developments in technologies and standards. A virtual machine prototype is provided as a demonstration of the use of a virtual representation for manufacturing data analytics.

Full Text Available Based upon a wide range of archive records, the article covers issues relating to particular aspects of life and living standards of silk weaving factory workers’ families in a village of Fryanovo of Moskovski county in XVIII — fi rst quarter of XIX centuries.Workers’ daily life was signifi cantly infl uenced by living conditions. It is via this article that we analyze dimensions and types of living premises provided to workers by the factory owners, as well as its improvements. The Fryanovo factory offi ce records that remain intact allow consideration of issues relating to food for workers, including sources for providing Fryanovo inhabitants with bread and other food products, the composition and the average amount thereof.One chapter of the article is specifi cally devoted to workers’ worship service attendance, as well as diff erences in religion belief of Fryanovo inhabitants. In addition to the orthodox Christian majority of its population, there were also Catholics and Old Believers among its inhabitants.The issues directly relating to working at the silk weaving factory include work schedule and rules, average age of workers, wage payment methods, as well as workers motivation by the silk weaving factory owner. Considered are the issues relating to employment of children and women at the silk weaving factory. An important part of the research relates to living conditions of non-working population groups: young children, retired and handicaps who were given some money or bread, on monthly bases, by silk weaving factory owners.Medical services for the silk weaving factory workers, personal taxation and other fees, participation by factory workers, in recruitments, penalties and fi nes system as implemented by the silk weaving factory in Fryanovo are also within the spectrum of questions that are discussed within the article.The fi nal chapter of the research points out the village inner life issues, such as alcohol abuse among

Factorial complexity and Morally Debatable Behaviors

Full Text Available Currently, from the scientific and professional practice point of view, comes out the necessity to know more about moral permissiveness, as it seems to be an increase in “moral relativism”.. Because it, it this is important to have tools to collect valid and reliable information about moral in social situations defined as social and personal behavior issue. This paper presents a technical note of The Morally Debatable Behaviors Scale (MDBS from Harding & Phillips (1986, which was developed in USA and mainly focused on young people and adults. This technical note makes direct reference to a recent Latin American study (Merino & Grimaldo, 2010; this article focuses on the internal structure and the problems associated with evidences of factorial complexity among items of the MDBS. This means that the interpretation of scores is not factorially simple and could not be achieved by a conceptual distinction between the latent constructs applied to the study sample.. The results in the previous study of the factorial complexity leads the researcher to decide whether an instrument for measuring this aspect may contain a reasonable amount of complexity that is consistent with what is in reality, or look for the unidimensional and simple structure.

Atmospheric aerosol system: An overview

Aerosols could play a critical role in many processes which impact on our lives either indirectly (e.g., climate) or directly (e.g., health). However, our ability to assess these possible impacts is constrained by our limited knowledge of the physical and chemical properties of aerosols, both anthropogenic and natural. This deficiency is attributable in part to the fact that aerosols are the end product of a vast array of chemical and physical processes. Consequently, the properties of the aerosol can exhibit a great deal of variability in both time and space. Furthermore, most aerosol studies have focused on measurements of a single aerosol characteristic such as composition or size distribution. Such information is generally not useful for the assessment of impacts because the degree of impact may depend on the integral properties of the aerosol, for example, the aerosol composition as a function of particle size. In this overview we discuss recent work on atmospheric aerosols that illustrates the complex nature of the aerosol chemical and physical system, and we suggest strategies for future research. A major conclusion is that man has had a great impact on the global budgets of certain species, especially sulfur and nitrogen, that play a dominant role in the atmospheric aerosol system. These changes could conceivably affect climate. Large-scale impacts are implied because it has recently been demonstrated that natural and pollutant aerosol episodes can be propagated over great distances. However, at present there is no evidence linking anthropogenic activities with a persistent increase in aerosol concentrations on a global scale. A major problem in assessing man's impact on the atmospheric aerosol system and on global budgets is the absence of aerosol measurements in remote marine and continental areas

To prepare for the PEP-II turn on, we have studied one commissioning strategy with simulated lattice errors. Features such as difference and absolute orbit analysis and correction are discussed. To prepare for the commissioning of the PEP-II injection line and high energy ring (HER), we have developed a system for on-line orbit analysis by merging two existing codes: LEGO and RESOLVE. With the LEGO-RESOLVE system, we can study the problem of finding quadrupole alignment and beam position (BPM) offset errors with simulated data. We have increased the speed and versatility of the orbit analysis process by using a command file written in a script language designed specifically for RESOLVE. In addition, we have interfaced the LEGO-RESOLVE system to the control system of the B-Factory. In this paper, we describe online analysis features of the LEGO-RESOLVE system and present examples of practical applications.

Baby factories and baby harvesting are relatively new terms that involve breeding, trafficking, and abuse of infants and their biological mothers. Since it was first described in a United Nations Educational, Scientific and Cultural Organization report in Nigeria in 2006, several more baby factories have been discovered over the years. Infertile women are noted to be major patrons of these baby factories due to the stigmatization of childless couples in Southern Nigeria and issues around cultural acceptability of surrogacy and adoption. These practices have contributed to the growth in the industry which results in physical, psychological, and sexual violence to the victims. Tackling baby factories will involve a multifaceted approach that includes advocacy and enacting of legislation barring baby factories and infant trafficking and harsh consequences for their patrons. Also, programs to educate young girls on preventing unwanted pregnancies are needed. Methods of improving awareness and acceptability of adoption and surrogacy and reducing the administrative and legal bottlenecks associated with these options for infertile couples should be explored to diminish the importance of baby factories. © The Author(s) 2015.

Comparison of drive systems for pulsed synchronous machines - an overview

International Nuclear Information System (INIS)

Baumgart, G.E.; Boenig, H.J.

1986-01-01

Magnetically confined plasma fusion experiments require large pulses of energy to be delivered into coil systems. One of the most effective methods of generating these high energy pulses is to convert stored inertial energy into electrical energy. Large synchronous generators of both the vertical and horizontal shaft type have been successfully used for this purpose. As the pulsed energy is delivered to the load, the inertial energy of the rotor of the machine is changed into electrical energy, causing the rotor to slow down. A drive system is required to accelerate the generator from standstill to the maximum operating speed and between load pulses from a reduced operating speed to the maximum speed. There are several types of drive systems that can be used for this application. An overview of six candidate drive systems is presented and comparisons of cost, performance, efficiency and line effects for these systems are described

Health monitoring systems have rapidly evolved during the past two decades and have the potential to change the way health care is currently delivered. Although smart health monitoring systems automate patient monitoring tasks and, thereby improve the patient workflow management, their efficiency in clinical settings is still debatable. This paper presents a review of smart health monitoring systems and an overview of their design and modeling. Furthermore, a critical analysis of the efficiency, clinical acceptability, strategies and recommendations on improving current health monitoring systems will be presented. The main aim is to review current state of the art monitoring systems and to perform extensive and an in-depth analysis of the findings in the area of smart health monitoring systems. In order to achieve this, over fifty different monitoring systems have been selected, categorized, classified and compared. Finally, major advances in the system design level have been discussed, current issues facing health care providers, as well as the potential challenges to health monitoring field will be identified and compared to other similar systems.

The need for intense muon beams for muon colliders [1] and for neutrino factories based on muon storage rings [2,3,4] leads to a concept of 1-4 MW proton beams incident a moving target that is inside a 20-T solenoid magnet, with a mercury jet as a preferred example. Novel technical issues for such a system include disruption of the mercury jet by the proton beam and distortion of the jet on entering the solenoid, as well as more conventional issues of materials lifetime and handling of activated materials in an intense radiation environment. As part of the R and D program [5] of the Neutrino Factory and Muon Collider Collaboration, R and D effort related to targetry is being performed within the context of BNL E951 [6], first results of which are discussed here and in other contributions to this conference

The Daniel K. Inouye Solar Telescope (DKIST, formerly the Advanced Technology Solar Telescope, ATST) is unique as, apart from protecting the telescope and its instrumentation from the weather, it holds the entrance aperture stop and is required to position it with millimeter-level accuracy. The compliance of the Enclosure design with the requirements, as of Final Design Review in January 2012, was supported by mathematical models and other analyses which included structural and mechanical analyses (FEA), control models, ventilation analysis (CFD), thermal models, reliability analysis, etc. During the Enclosure Factory Assembly and Testing the compliance with the requirements has been verified using the real hardware and the models created during the design phase have been revisited. The tests performed during shutter mechanism subsystem (crawler test stand) functional and endurance testing (completed summer 2013) and two comprehensive system-level factory acceptance testing campaigns (FAT#1 in December 2013 and FAT#2 in March 2014) included functional and performance tests on all mechanisms, off-normal mode tests, mechanism wobble tests, creation of the Enclosure pointing map, control system tests, and vibration tests. The comparison of the assumptions used during the design phase with the properties measured during the test campaign provides an interesting reference for future projects.

"Mixing" as an ethnoetiology of HIV/AIDS in Malaysia's multinational factories.

Science.gov (United States)

Root, Robin

2006-09-01

Minah Karan, the stigmatizing label appended to Malay factory women in the 1980s, signaled a dangerous female sexuality that risked spreading beyond the factory gates and infecting Malaysia's idea(l)s of its traditional kampung culture. This article narrates how Minah Karan, as the former antihero of development, was reconstituted in the 1990s, with the government's labeling of factories as "high-risk settings" for HIV/AIDS. This is an ethnoetiology based not on any evidential epidemiological data but on the racial and gendered "mixing" that transpires behind factory walls: a fear that the "mixing of the sexes" means ipso facto "sexual mixing" among the races. The article demonstrates how importation of the high-risk label articulates at the local level the new and contested linkages, economic, religious, and scientific, constitutive of globalization. The pragmatic nature and imperatives of this high-risk process are discerned in factory women's accounts of how they negotiate the interactional imperatives of factory work, because transnational structures of productivity violate the social boundaries that have long connoted political stability, moral integrity, ethnic community, and individual safety. The article concludes by questioning whether ethnoetiologies, especially when they concern sexual networks, become social etiologies, because this would locate ethnoetiologies as central to conventional public health praxis rather than as ethnographic exotica in the margins.

1997-01-01

Factorial and fractal methods were applied to nuclear-electromagnetic cascades in the atmosphere (γ families) to find sensitivity of these methods to multiparticle fluctuations in γ families. Averaged parameters of factorial and fractal methods of the real families were compared with the same quantities for the statistical set of random families. The correlations between the same parameters for families divided into sectors and into rings are studied. The correlations between different parameters for the same families divided into sectors are investigated

Natural computing for mechanical systems research: A tutorial overview

Science.gov (United States)

Worden, Keith; Staszewski, Wieslaw J.; Hensman, James J.

2011-01-01

A great many computational algorithms developed over the past half-century have been motivated or suggested by biological systems or processes, the most well-known being the artificial neural networks. These algorithms are commonly grouped together under the terms soft or natural computing. A property shared by most natural computing algorithms is that they allow exploration of, or learning from, data. This property has proved extremely valuable in the solution of many diverse problems in science and engineering. The current paper is intended as a tutorial overview of the basic theory of some of the most common methods of natural computing as they are applied in the context of mechanical systems research. The application of some of the main algorithms is illustrated using case studies. The paper also attempts to give some indication as to which of the algorithms emerging now from the machine learning community are likely to be important for mechanical systems research in the future.

A factorial experiment on image quality and radiation dose

International Nuclear Information System (INIS)

Norrman, E.; Persliden, J.

2005-01-01

To find if factorial experiments can be used in the optimisation of diagnostic imaging, a factorial experiment was performed to investigate some of the factors that influence image quality, kerma area product (KAP) and effective dose (E). In a factorial experiment the factors are varied together instead of one at a time, making it possible to discover interactions between the factors as well as major effects. The factors studied were tube potential, tube loading, focus size and filtration. Each factor was set to two levels (low and high). The influence of the factors on the response variables (image quality, KAP and E) was studied using a direct digital detector. The major effects of each factor on the response variables were estimated as well as the interaction effects between factors. The image quality, KAP and E were mainly influenced by tube loading, tube potential and filtration. There were some active interactions, for example, between tube potential and filtration and between tube loading and filtration. The study shows that factorial experiments can be used to predict the influence of various parameters on image quality and radiation dose. (authors)

On the use of metabolic control analysis in the optimization of cyanobacterial biosolar cell factories.

Science.gov (United States)

Angermayr, S Andreas; Hellingwerf, Klaas J

2013-09-26

Oxygenic photosynthesis will have a key role in a sustainable future. It is therefore significant that this process can be engineered in organisms such as cyanobacteria to construct cell factories that catalyze the (sun)light-driven conversion of CO2 and water into products like ethanol, butanol, or other biofuels or lactic acid, a bioplastic precursor, and oxygen as a byproduct. It is of key importance to optimize such cell factories to maximal efficiency. This holds for their light-harvesting capabilities under, for example, circadian illumination in large-scale photobioreactors. However, this also holds for the "dark" reactions of photosynthesis, that is, the conversion of CO2, NADPH, and ATP into a product. Here, we present an analysis, based on metabolic control theory, to estimate the optimal capacity for product formation with which such cyanobacterial cell factories have to be equipped. Engineered l-lactic acid producing Synechocystis sp. PCC6803 strains are used to identify the relation between production rate and enzymatic capacity. The analysis shows that the engineered cell factories for l-lactic acid are fully limited by the metabolic capacity of the product-forming pathway. We attribute this to the fact that currently available promoter systems in cyanobacteria lack the genetic capacity to a provide sufficient expression in single-gene doses.

Preparation of an Evaluated HACCP- Plan in Order to Implementation in Iranian Mineral Water Factories for Avoiding the Common Food Safety Hazards in Such Industries

Directory of Open Access Journals (Sweden)

Amin Kiyani

2014-12-01

Full Text Available Background: consumption of mineral waters in the world has increased in recent years, and also concerns of consumers about its contamination are growing. Thereby, implementation of such a protective system as HACCP can prevent contamination of waters by different agents. This research aimed to develop an HACCP-Plan standard for mineral waters manufacturing factories in Iran. Methods: In current study, like production lines, polyethylene terephthalate (PET containers packaging, warehouses and laboratories sections of factories were observed from view of production and quality control. To monitor, control and restrict the hazards, seven principles of HACCP were considered. In continue applicable solutions were presented inclusive and practically for all factories. Required information were verified and presented through investigation of national and international standards. Results: The results shown that lack of sanitizing mineral water supplies and factories environment, incomplete water treatment, non-standard production of PET bottles, improper storage of raw materials and final product, and lack of inspection of equipment led to the increasing health hazards of the product and endanger the consumers health. Conclusion: In order to produce safe mineral water, it is necessary to sanitize the water supplies and factory environment. In addition, the process of water treatment and the production of PET bottles must be according to national and international standards. As the implementation of the HACCP system in various mineral water producing factories is not same, application of developed system in this research will be effective to standardize the implementation of this system in plants.

Lymphocyte-based model systems for allergy research: a historic overview.

Science.gov (United States)

Neunkirchner, Alina; Schmetterer, Klaus G; Pickl, Winfried F

2014-01-01

During the last decades, a multitude of studies applying distinct in vitro and in vivo model systems have contributed greatly to our better understanding of the initiation and regulation of inflammatory processes leading to allergic diseases. Over the years, it has become evident that among lymphocytes, not only IgE-producing B cells and allergy-orchestrating CD4(+) helper cells but also cytotoxic CD8(+) T cells, γδ-T cells and innate lymphoid cells, as well as regulatory lymphocytes, might critically shape the immune response towards usually innocuous allergens. In this review, we provide a historic overview of pioneering work leading to the establishment of important lymphocyte-based model systems for allergy research. Moreover, we contrast the original findings with our currently more refined knowledge to appreciate the actual validity of the respective models and to reassess the conclusions obtained from them. Conflicting studies and interpretations are identified and discussed. The tables are intended to provide an easy overview of the field not only for scientists newly entering the field but also for the broader readership interested in updating their knowledge. Along those lines, herein we discuss in vitro and in vivo approaches to the investigation of lymphocyte effector cell activation, polarization and regulation, and describe depletion and adoptive transfer models along with gene knockout and transgenic (tg) methodologies. In addition, novel attempts to establish humanized T cell antigen receptor tg mouse models for allergy research are described and discussed. © 2014 S. Karger AG, Basel.

Science.gov (United States)

Muthusamy, A; Jayabalan, N

2001-10-01

The effect of sago and sugar factory effluents was studied on Gossypium hirsutum L. var. MCU 5 and MCU 11. Plants were irrigated with 0, 25, 50, 75 and 100% of effluents of both factories. At lower concentration (25%) of sugar factory effluents had stimulatory effect on all biochemical contents observed. Moreover, all concentration of sago factory effluents were found to have inhibitory effect on all biochemical contents except proline content which increased with increasing concentration of both the effluents. Plants growing on adjacent to sago and sugar factories or they irrigated with such type of polluted water, may accumulate the heavy metals found in both the effluents, at higher levels in plant products and if consumed may have similar effect on living organisms.

An asymmetric Β-factory based on PEP

Oddone, P.

1989-01-01

This paper reviews the motivation for building asymmetric B-factories based on storage rings and describes the current LBL/SLAC study to develop such a factory by modifying the PEP storage ring and adding a new low energy (2.5-3 GeV) storage ring. Collisions between the beam of the modified high energy PEP ring and the low energy ring lead to a luminosity of 2 x 10 33 cm- 2 sec - 1 at E cm = Y(4s) with currents of 0.8A in each beam. Further increases in current can lead to luminosities close to 10 34 cm - 2 sec - 1

Bailey, Timothy; Bode, Bruce W; Christiansen, Mark P; Klaff, Leslie J; Alva, Shridhara

2015-11-01

The purpose of the study was to evaluate the performance and usability of the FreeStyle(®) Libre™ Flash glucose monitoring system (Abbott Diabetes Care, Alameda, CA) for interstitial glucose results compared with capillary blood glucose results. Seventy-two study participants with type 1 or type 2 diabetes were enrolled by four U.S. clinical sites. A sensor was inserted on the back of each upper arm for up to 14 days. Three factory-only calibrated sensor lots were used in the study. Sensor glucose measurements were compared with capillary blood glucose (BG) results (approximately eight per day) obtained using the BG meter built into the reader (BG reference) and with the YSI analyzer (Yellow Springs Instrument, Yellow Springs, OH) reference tests at three clinic visits (32 samples per visit). Sensor readings were masked to the participants. The accuracy of the results was demonstrated against capillary BG reference values, with 86.7% of sensor results within Consensus Error Grid Zone A. The percentage of readings within Consensus Error Grid Zone A on Days 2, 7, and 14 was 88.4%, 89.2%, and 85.2%, respectively. The overall mean absolute relative difference was 11.4%. The mean lag time between sensor and YSI reference values was 4.5±4.8 min. Sensor accuracy was not affected by factors such as body mass index, age, type of diabetes, clinical site, insulin administration, or hemoglobin A1c. Interstitial glucose measurements with the FreeStyle Libre system were found to be accurate compared with capillary BG reference values, with accuracy remaining stable over 14 days of wear and unaffected by patient characteristics.

Evolution of the Factory 1975-2006

International Nuclear Information System (INIS)

2006-01-01

Since it was founded in 1973. Equipos Nucleares (ENSA) has been actively present in the nuclear market. This was the reason for its creation and for which it was organized from the very beginning, by designing a company with a nuclear structure and mentality. The author reviews the history and evolution of the Factory- more than a workshop- and describes its different stages, which were strongly affected by the unexpected evolution of a diminishing market- an inexistent market the likes to say- and also stresses the extraordinary difficulty of its work and the determination to remain in the nuclear market. He acknowledges the people and the culture of ENSA emphasizing their dedication, generosity, flexibility, training and enthusiasm, and stresses their stake in being the best and to attain excellence in the quality of supplies, meeting deadlines and customer satisfaction, identifying these as fundamental factors of the company's legacy. Having a better Factory is possible by improving its technological capability through researching and developing its processes, automating and robotizing manufacturing and inspection activities, and simplifying its operating systems. A result of these efforts is the continuous international presence as a supplier and collaborator with the world's leading designers, which has consolidated it as a reference supplier on the American market. Of not is the supply to the market of its different product lines a result of combining its design and manufacturing capabilities with its flexibility and size, all of which contribute to ENSA's wealth, diversity and appeal. ENSA is aware of the forthcoming resurgence of the new nuclear market. It is preparing for the future by renewing and upgrading its manufacturing facilities and implementing new systems techniques- Lean Manufacturing and Six Sigma-into its Annual Improvement Plans to favor and drive its technological capability and competitiveness and to respond to the increasingly demanding

2010-07-01

Axial flow fans used in underground mining are also commonly used in subway tunnel ventilation fans to provide an evacuation path during a tunnel fire emergency. The axial flow fans provide sufficient air velocity to the fire site to prevent backlayering of smoke against the incoming airflow. Since the tunnels are used by the public, advance testing of fans and motors is conducted to confirm that the equipment will perform as specified during a fire. This paper discussed some of the advantages derived from conducting fan factory tests for tunnel projects that would also apply to mining applications. It also described other benefits from testing that are unique to mining. External factors that may cause the fan performance to vary considerably from the predicted performance measured at the factory were also discussed. These included air density changes and system effects produced by poorly designed shaft configurations and fan inlet ductwork. 11 refs., 6 figs.

Concept of data storage prototype for Super-C-Tau factory detector

International Nuclear Information System (INIS)

Maximov, D.A.

2017-01-01

The physics program of experiments at the Super- c τ factory with a peak luminosity of 10 35 cm −2 s −1 leads to high requrements for Data Acquisition and Data Storage systems. Detector data storage is one of the key component of the detector infrastructure, so it must be reliable, highly available and fault tolerant shared storage. It is mostly oriented (from end user point of view) for sequential but mixed read and write operations and is planed to store large data blocks (files). According to CDR of Super-C-Tau factory detector data storage must have very high performance (up to 1 Tbps in both directions simultaneously) and have significant volume (tens and hundreds of Petabytes). It is decided to build a series of prototypes with growing capabilities to investigate storage and neighboring technologies. First prototype of data storage is aimed to develop and test basic components of detector data storage system such as storage devices, networks and software. This prototype is designed to be capable to work with data rate of order 10 Gbps. It is estimated that about 5 modern computers with about 50 disks in total should be enough to archive required performance. The prototype will be based on Ceph storage technology. Ceph is a distributed storage system which allows to create storage solutions with very flexible design, high availability and scalability.

In June, 1989, the study group for exploring the feasibility of B meson physics using an asymmetric energy accelerator was organized. This report is the summary of the results of the works that this study group carried out in nine months, and is the Japanese edition of the report of English edition 'Task Force Report on Asymmetric B-factory at KEK'. The activity plan of the study group was to make up the plan exceeding the preceding CLEO-2 experiment by utilizing the features of an asymmetric B-factory. Under this plan, the activities have been carried out by the study meetings twice every week on the physics side and once every two weeks on the accelerator side. Besides, in two study meetings held in October and December, 1989, several persons who have engaged in the research on B meson physics actually in foreign countries were invited, and the discussion was carried out. At present toward the materialization of the plan, the concrete investigation of accelerators and measuring instruments was begun. The significance of a B-factory and the construction project, the physics of a B-factory, the experimental method and the plan for an accelerator are reported. (K.I.)

Jaipakdee, Napaphak; Limpongsa, Ekapol; Pongjanyakul, Thaned

2016-01-01

The objective of this study was to apply fractional factorial and multi-response optimization designs using desirability function approach for developing topical microemulsions. Minoxidil (MX) was used as a model drug. Limonene was used as an oil phase. Based on solubility, Tween 20 and caprylocaproyl polyoxyl-8 glycerides were selected as surfactants, propylene glycol and ethanol were selected as co-solvent in aqueous phase. Experiments were performed according to a two-level fractional factorial design to evaluate the effects of independent variables: Tween 20 concentration in surfactant system (X1), surfactant concentration (X2), ethanol concentration in co-solvent system (X3), limonene concentration (X4) on MX solubility (Y1), permeation flux (Y2), lag time (Y3), deposition (Y4) of MX microemulsions. It was found that Y1 increased with increasing X3 and decreasing X2, X4; whereas Y2 increased with decreasing X1, X2 and increasing X3. While Y3 was not affected by these variables, Y4 increased with decreasing X1, X2. Three regression equations were obtained and calculated for predicted values of responses Y1, Y2 and Y4. The predicted values matched experimental values reasonably well with high determination coefficient. By using optimal desirability function, optimized microemulsion demonstrating the highest MX solubility, permeation flux and skin deposition was confirmed as low level of X1, X2 and X4 but high level of X3.

The effects of outsourcing on occupational health and safety: a comparative study of factory-based workers and outworkers in the Australian clothing industry.

Science.gov (United States)

Mayhew, C; Quinlan, M

1999-01-01

Outsourcing has become increasingly widespread throughout industrialized societies over the past 20 years. Accompanying this has been a renewed growth in home-based work, sometimes using new technologies (telework) but also entailing a re-emergence of old forms, such as clothing outwork, used extensively 100 years ago. A growing body of research indicates that changes to work organization associated with outsourcing adversely affect occupational health and safety (OHS), both for outsourced workers and for those working alongside them. This study assessed the OHS implications of the shift to home-based workers in the Australian clothing industry by systematically comparing the OHS experiences of 100 factory-based workers and 100 outworkers. The level of self-reported injury was over three times higher among outworkers than factory-based workers undertaking similar tasks. The most significant factor explaining this difference was the payment system. All outworkers were paid solely by the piece, whereas factory workers were paid either under a time plus production bonus system or solely on a time basis. While the incidence of injury was far higher among outworkers, factory-based workers paid under an incentive system reported more injuries than those paid solely on a time basis. Increasing injury was correlated with piecework payment systems.

1990-01-01

The normalization of factorial moments of intermittency, which is often the subject of controverses, is justified and (re-)derived from the general assumption of multi-Poissonian statistical noise in the production of particles at high-energy. Correction factors for the horizontal vs. Vertical analyses are derived in general cases, including the factorial multi-bin correlation moments

Report on energy conservation. Potential feasibility study on energy conservation at the national textile factories (Energy-saving equipment)

2001-03-01

In consideration of the future CDM project, feasibility study was made on the energy conservation/cost reduction in national textile factories in Egypt. In textile factories in Egypt, the steam by oil fueled boiler is used in dyeing, drying and other production processes. In this study, studied were the energy conservation effect, greenhouse effect gas reduction effect and economical efficiency in the case of using electric power/steam by the natural gas fueled cogeneration system. As a result of the study, the energy conservation effect in 6 national textile factories became 13% on average, which equals to the conservation of 15,000 toe per year. The greenhouse effect gas reduction effect also became 13%, which equals to the reduction of approximately 46,000 t-CO2 per year. As to the economical efficiency, the depreciation period of investment became 4.0-8.6 years (5.6 years on average). In the light of the operation period of cogeneration facilities of 15 years, it was indicated that the system was very advantageous. (NEDO)

A Profile-Based Framework for Factorial Similarity and the Congruence Coefficient.

Science.gov (United States)

Hartley, Anselma G; Furr, R Michael

2017-01-01

We present a novel profile-based framework for understanding factorial similarity in the context of exploratory factor analysis in general, and for understanding the congruence coefficient (a commonly used index of factor similarity) specifically. First, we introduce the profile-based framework articulating factorial similarity in terms of 3 intuitive components: general saturation similarity, differential saturation similarity, and configural similarity. We then articulate the congruence coefficient in terms of these components, along with 2 additional profile-based components, and we explain how these components resolve ambiguities that can be-and are-found when using the congruence coefficient. Finally, we present secondary analyses revealing that profile-based components of factorial are indeed linked to experts' actual evaluations of factorial similarity. Overall, the profile-based approach we present offers new insights into the ways in which researchers can examine factor similarity and holds the potential to enhance researchers' ability to understand the congruence coefficient.

Status of neutrino factory and muon collider R and D

International Nuclear Information System (INIS)

Zisman, M.S.

2001-01-01

A significant worldwide R and D effort is presently directed toward solving the technical challenges of producing, cooling, accelerating, storing, and eventually colliding beams of muons. Its primary thrust is toward issues critical to a Neutrino Factory, for which R and D efforts are under way in the U.S., via the Neutrino Factory and Muon Collider Collaboration (MC); in Europe, centered at CERN; and in Japan, at KEK. Under study and experimental development are production targets handling intense proton beams (1-4 MW), phase rotation systems to reduce beam energy spread, cooling channels to reduce transverse beam emittance for the acceleration system, and storage rings where muon decays in a long straight section provide a neutrino beam for a long-baseline (3000 km) experiment. Critical experimental activities include development of very high gradient normal conducting RF (NCRF) and superconducting RF (SCRF) cavities, high-power liquid-hydrogen absorbers, and high-field superconducting solenoids. Components and instrumentation that tolerate the intense decay products of the muon beam are being developed for testing. For a high-luminosity collider, muons must be cooled longitudinally as well as transversely, requiring an emittance exchange scheme. In addition to the experimental R and D effort, sophisticated theoretical and simulation tools are needed for the design. Here, the goals, present status, and future R and D plans in these areas will be described

A possibility of usage of accelerators of neutron as well as meson factories is considered. Parameters of linear and cyclic accelerators are given, which are employed as meson factories and as base for developing intense neutron generators. It is emphasized that the principal aim of developing neutron generators on the base of high current proton accelerators is production of intense neutron fluxes with a present energy spectrum. Production of tens-and-hundreds milliampere currents at the energy of 800-1000 MeV is considered at present for two types of accelerating facilities viz. linear accelerators under continuous operating conditions and cyclotrons with strong focusing. Quantitative evaluations of developing high-efficiency linear and cyclic accelerators are considered. The basic parameters of an ccelerating complex are given, viz. linear accelerator-injector and 800 MeV isochronous cyclotron. The main problems associated with their realization are listed [ru

Limit values in special agreements between factories and sewage works

International Nuclear Information System (INIS)

Lundstroem, Yrjoe

1987-01-01

The operation of sewage works is controlled in Finland by the water and health authorities. These authorities set special quality demands for the effluent from sewage treatment plants into the recipient. Also other wastes from treatment plants, mainly sludges, have special regulations and operational target values. Sewage works have to achieve the aim goals and limit values set. In order to fulfill the regulations, sewage works impose such limit values on factory wastewaters that there will be no problems at the treatment plants. Sewage works can act in two ways: - require the factory to operate in such a way that the limit values are not exceeded, - the factory pays a certain sum of money to the sewage works, which takes care of the whole problem. It can be said in general, that it is not possible to get rid of harmful substances by payment to the sewage works if the substances cause treatment problems or problems in sludge disposal. If the factory produces wastewater that contains a higher organic load, more suspended solids or a higher nutrient load than normal sanitary wastewater, the problem is most often solved by paying an extra fee to the sewage works

In particular, it looks closely at the life experiences of a factory worker, two unemployed migrants and a union leader and it illustrates their narratives of hard work and “luck” in the quest for personal growth. It explores the various social networks that sustain life among factory workers while focusing specifically on the role of unionism as a symbolic and material resource to navigate through the precariousness and hardship of salary work and unemployment.

Kaon factories

Craddock, M.K.

1983-03-01

Kaon factories would provide beams 100-1000 times more intense than those available from present accelerators in the 10-30 GeV range. More intense or cleaner secondary beams of kaons, antiprotons and neutrinos would be of particular interest for high precision experiments and studies of rare processes in both particle and nuclear physics, e.g. symmetry violations in K-decay, neutrino scattering, meson and baryon spectroscopy, hypernuclei, exotic atoms, K + studies of nuclear density and resonance propagation in nuclei. The various accelerators proposed include both fast-cycling synchrotrons providing 100 μA proton beams at 15 to 32 GeV and superconducting isochronous ring cyclotrons giving 100-400 μA at up to 15 GeV. This paper describes these designs and the various technical problems associated with them

Environmental impact of cheese production: A case study of a small-scale factory in southern Europe and global overview of carbon footprint.

Science.gov (United States)

Canellada, Fernando; Laca, Amanda; Laca, Adriana; Díaz, Mario

2018-09-01

The environmental performance of a small-scale cheese factory sited in a NW Spanish region has been analysed by Life Cycle Assessment (LCA) as representative of numerous cheese traditional factories that are scattered through the European Union, especially in the southern countries. Inventory data were directly obtained from this facility corresponding to one-year operation, and the main subsystems involved in cheese production were included, i.e. raw materials, water, electricity, energy, cleaning products, packaging materials, transports, solid and liquid wastes and gas emissions. Results indicated that the environmental impacts derived from cheese making were mainly originated from raw milk production and the natural land transformation was the most affected of the considered categories. On the contrary, the manufacturing of packaging material and other non-dairy ingredients barely influenced on the total impact. Additionally, an average carbon footprint of the cheeses produced in the analysed facility has also been calculated, resulting milk production and pellet boiler emissions the most contributing subsystems. Furthermore, it was notable the positive environmental effect that entailed the direct use of whey as animal feed, which was considered in this study as avoided fodder. Finally, a revision of published works regarding the environmental performance of cheese production worldwide was provided and compared to results found in the present work. According to the analysed data, it is clear that the content of fat and dry extract are determinant factors for the carbon footprint of cheeses, whereas the cheesemaking scale and the geographical area have a very low effect.

Overview of the CANDU fuel handling system for advanced fuel cycles

International Nuclear Information System (INIS)

Koivisto, D.J.; Brown, D.R.

1997-01-01

Because of its neutron economies and on-power re-fuelling capabilities the CANDU system is ideally suited for implementing advanced fuel cycles because it can be adapted to burn these alternative fuels without major changes to the reactor. The fuel handling system is adaptable to implement advanced fuel cycles with some minor changes. Each individual advanced fuel cycle imposes some new set of special requirements on the fuel handling system that is different from the requirements usually encountered in handling the traditional natural uranium fuel. These changes are minor from an overall plant point of view but will require some interesting design and operating changes to the fuel handling system. Some preliminary conceptual design has been done on the fuel handling system in support of these fuel cycles. Some fuel handling details were studies in depth for some of the advanced fuel cycles. This paper provides an overview of the concepts and design challenges. (author)

The proposed linear Accelerator that accelerates muons from 190 MeV to 2.45 GeV will use superconducting solenoids for focusing the muon beam. The accelerator will use superconducting RF cavities. These cavities are very sensitive to stay magnetic field from the focusing magnets. Superconducting solenoids can produce large stray fields. This report describes the 201.25 MHz acceleration system for the neutrino factory. This report also describes a focusing solenoid that delivers almost no stray field to a neighboring superconducting RF cavity

The aim of the present study was to develop optimal air-conditioning systems for plant factories. To verify the effect of particular air-conditioning and lighting systems, cultivation experiments were performed with frill-lettuce for two weeks. In the present study, the relationship between the cultivation condition, the yield (i.e., increase in edible portion weight), and the functional components were discussed. Based on the measured data, increased photosynthetic photon flux density increased antioxidative activity and edible portion weight, possibly because high light intensities are stressful for frill lettuce. Antioxidative activity also increased under conditions of low CO2 concentration, weak and strong winds, and high air temperature because these conditions became stresses for the plants. However, a decrease in edible portion weight was observed under these conditions, implying there is a negative correlation between antioxidative activity and edible portion weight.

Application of factorial design for the ab initio study of cis- and trans-1,2 dihaloethylene stabilities

Directory of Open Access Journals (Sweden)

Silva João Bosco P. da

2000-01-01

Full Text Available The chemometric technique Two Level Factorial Design was used to evaluate the principal and interaction effects of wave function modifications on calculated energy differences (DE between the cis and trans isomers of 1,2-dihaloethylenes, C2H2X2 (X=F and Cl. The factorial profile of DE is quite different for these systems. The addition of polarization and diffuse functions to the basis set have the largest effects in describing cis 1,2-difluoroethylene as the most stable isomer. In contrast electronic correlation, at the MP2 level, and the inclusion of polarization functions in the basis set have the largest effects in describing the cis form as the most stable one in the 1,2-dichloroethylenes. In both systems the interaction effects are smaller than the principal effects.

2017-01-24

Most workers in auto part factories in Thailand are usually exposed to excessive noise in their workplace. This study aimed to assess the level of occupational noise-induced hearing loss and investigate risk factors causing hearing loss in auto part factory workers in the welding units in Thailand. This was a cross-sectional study. One hundred eighty subjects were recruited from 356 workers in the welding unit of three factories. Sixty eligible subjects in each factory were selected by systemic random sampling. The subjects were interviewed using a face-to-face questionnaire. Noise exposure levels and audiograms were measured by a noise dosimeter and an audiometer, respectively. The findings confirmed that noise exposure levels of 86-90 dB (A) and exceeding 90 dB (A) significantly increased the risk of hearing loss in either ear. A noise exposure level exceeding 90 dB (A) significantly increased the prevalence of hearing loss in both ears. Regarding, a 10-pack-year smoking history increased the prevalence of hearing loss in either ear or both ears. In addition, subjects with employment duration exceeding 10 years significantly developed hearing loss in either ear. The engineering control or personal control by wearing hearing protection device should be used to decrease noise exposure levels lower than 85 dB (A) for 8 h. Moreover, if the exposure level reaches 85 dB (A) for 8 h, the employer needs to implement a hearing conservation program in the workplace.

CONFOUNDING STRUCTURE OF TWO-LEVEL NONREGULAR FACTORIAL DESIGNS

Institute of Scientific and Technical Information of China (English)

Ren Junbai

2012-01-01

In design theory,the alias structure of regular fractional factorial designs is elegantly described with group theory.However,this approach cannot be applied to nonregular designs directly. For an arbitrary nonregular design,a natural question is how to describe the confounding relations between its effects,is there any inner structure similar to regular designs? The aim of this article is to answer this basic question.Using coefficients of indicator function,confounding structure of nonregular fractional factorial designs is obtained as linear constrains on the values of effects.A method to estimate the sparse significant effects in an arbitrary nonregular design is given through an example.

Today, many raw materials used in factories may have a dangerous effect on the physiological system of workers. One of them which is widely used in the polyurethane factories is diisocyanates. These compounds are widely used in surface coatings, polyurethane foams, adhesives, resins, elastomers, binders, and sealants. Exposure to diisocyanates causes irritation to the skin, mucous membranes, eyes, and respiratory tract. Hexamethylene diamine (HDA) is metabolite of hexamethylene diisocyanate (HDI). It is an excretory material by worker's urine who is exposed to HDI. Around 100 air samples were collected from five defined factories by midget impinger which contained dimethyl sulfoxide absorbent as a solvent and tryptamine as reagent. Samples were analyzed by high-performance liquid chromatography with EC\\UV detector using NIOSH 5522 method of sampling. Also, 50 urine samples collected from workers were also analyzed using William's biological analysis method. The concentration of HDI into all air samples were more than 88 microg/m(3), and they have shown high concentration of pollutant in the workplaces in comparison with NIOSH standard, and all of the workers' urine were contaminated by HDA. The correlation and regression test were used to obtain statistical model for HDI and HDA, which is useful for the prediction of diisocyanates pollution situation in the polyurethane factories.

Evaluation of a Cogeneration Plant with Integrated Fuel Factory; Integrerad braenslefabrik med kraftvaermeanlaeggning - en utvaerdering

Atterhem, Lars

2002-12-01

A feasibility study was carried out in 1993 by Skellefteaa Kraft AB, to analyse the technical and economical possibilities to build a new baseload district heating production plant. The conclusion from the study was that, as a first step, a new cogeneration plant, based on a circulating fluidised bed boiler, should be built. The commissioning of the cogeneration plant took place in autumn 1996. The plant was prepared for a future integration with a biofuel drying process for pellets production. During spring 1996 an investment decision was taken and the fuel factory was erected in may 1997. Vaermeforsk Service AB has financed this research project and the Swedish state energy program (Fabel) has contributed with 33,7 Million SEK to the financing of the recovery electric power generation part of the fuel factory. The aim with this research project has been to evaluate and compare the integrated cogeneration plant fuel factory concept with a conventional co-generation plant, specially when it comes to increased power generation. The fuel factory comprises of fuel feeding system, fuel dryer, steam converter from fuel moisture to low pressure process steam, low pressure condensing turbine, cooling water system, fuel pellets production and storage with ship loading plant in the harbour of Skellefteaa. The steam to the fuel factory is extracted from the cogeneration turbine at a pressure level between 12-26 bar and the extraction flow has then already generated power in the cogeneration turbine. Power is also generated in the low pressure condensing turbine of the fuel factory. The low pressure steam is generated with fuel moisture in the steam converter. During the first years of operation there has been both conventional commissioning problems but also technical problems related to the new process concept. The last are for example corrosion and erosion problems, fouling problems of heat exchangers, capacity and leakage problems. The performance goals of the fuel

Phenomenology of scaled factorial moments and future approaches for correlation studies

International Nuclear Information System (INIS)

Seibert, D.

1991-01-01

We show that the definitions of the exclusive and inclusive scaled factorial moments are not equivalent, and propose the use of scaled factorial moments that reduce to the exclusive moments in the case of fixed multiplicity. We then present a new derivation of the multiplicity scaling law for scaled factorial moment data. This scaling law seems to hold, independent of collision energy, for events with fixed projectile and target. However, deviations from this scaling law indicate that correlations in S-Au collisions are 30 times as strong as correlations in hadronic collisions. Finally, we discuss 'split-bin' correlation functions, the most useful tool for future investigations of these anomalously strong hadronic correlations. (orig.)

A Fuzzy Collaborative Forecasting Approach for Forecasting the Productivity of a Factory

Directory of Open Access Journals (Sweden)

Yi-Chi Wang

2013-01-01

Full Text Available Productivity is always considered as one of the most basic and important factors to the competitiveness of a factory. For this reason, all factories have sought to enhance productivity. To achieve this goal, we first need to estimate the productivity. However, there is considerable degree of uncertainty in productivity. For this reason, a fuzzy collaborative forecasting approach is proposed in this study to forecast the productivity of a factory. First, a learning model is established to estimate the future productivity. Subsequently, the learning model is converted into three equivalent nonlinear programming problems to be solved from various viewpoints. The fuzzy productivity forecasts by different experts may not be equal and should therefore be aggregated. To this end, the fuzzy intersection and back propagation network approach is applied. The practical example of a dynamic random access memory (DRAM factory is used to evaluate the effectiveness of the proposed methodology.

Hong, Kuk-Ki; Nielsen, Jens

2012-08-01

Metabolic engineering is the enabling science of development of efficient cell factories for the production of fuels, chemicals, pharmaceuticals, and food ingredients through microbial fermentations. The yeast Saccharomyces cerevisiae is a key cell factory already used for the production of a wide range of industrial products, and here we review ongoing work, particularly in industry, on using this organism for the production of butanol, which can be used as biofuel, and isoprenoids, which can find a wide range of applications including as pharmaceuticals and as biodiesel. We also look into how engineering of yeast can lead to improved uptake of sugars that are present in biomass hydrolyzates, and hereby allow for utilization of biomass as feedstock in the production of fuels and chemicals employing S. cerevisiae. Finally, we discuss the perspectives of how technologies from systems biology and synthetic biology can be used to advance metabolic engineering of yeast.

From field to factory-Taking advantage of shop manufacturing for the pebble bed modular reactor

International Nuclear Information System (INIS)

Wallace, Edward; Matzie, Regis; Heiderd, Roger; Maddalena, John

2006-01-01

The move of nuclear plant construction from the field to the factory for small, advanced pebble bed modular reactor (PBMR) designs has significant benefits compared to traditional light water reactor (LWR) field oriented designs. The use of modular factory construction techniques has a growing economic benefit over time through well-established process learning applications. This paper addresses the basic PBMR design objectives and commercialization model that drive this approach; provides a brief technical description of the PBMR design and layout with representative CAD views and discusses derived figures of merit highlighting the relative simplicity of PBMR compared to a modern LWR. The discussion emphasizes that more of PBMR can be built in the factory due to the simple design of a direct helium Brayton cycle compared to an indirect LWR steam cycle with its associated equipment. For the PBMR design there are fewer and less cumbersome auxiliary and safety systems with their attendant support requirements. Additionally, the labor force economic efficiency for nuclear projects is better in the factory than in the field, including consideration of labor costs and nuclear quality programs. Industrial learning is better in the factory because of the more controlled environment, mechanization optimization opportunities and because of the more stable labor force compared to the field. Supply chain benefits are more readily achievable with strategic contracts for module suppliers. Although building a nuclear power plant is not a typical high volume manufacturing process, for the PBMR-type of plant, with its high degree of standardization and relatively small, simplified design, the shift to factory work has a significant impact on overall project cost due to earlier identification and better coordination of parallel construction paths. This is in stark contrast to the construction of a large LWR in the past. Finally, the PBMR modular plant concept continues at the

Resource use efficiency of closed plant production system with artificial light: concept, estimation and application to plant factory.

Science.gov (United States)

Kozai, Toyoki

2013-01-01

Extensive research has recently been conducted on plant factory with artificial light, which is one type of closed plant production system (CPPS) consisting of a thermally insulated and airtight structure, a multi-tier system with lighting devices, air conditioners and fans, a CO2 supply unit, a nutrient solution supply unit, and an environment control unit. One of the research outcomes is the concept of resource use efficiency (RUE) of CPPS.This paper reviews the characteristics of the CPPS compared with those of the greenhouse, mainly from the viewpoint of RUE, which is defined as the ratio of the amount of the resource fixed or held in plants to the amount of the resource supplied to the CPPS.It is shown that the use efficiencies of water, CO2 and light energy are considerably higher in the CPPS than those in the greenhouse. On the other hand, there is much more room for improving the light and electric energy use efficiencies of CPPS. Challenging issues for CPPS and RUE are also discussed.

This study aims to investigate factors affecting weakly basic drugs liposomal systems. Resolution V fractional factorial design (2 V 5-1 ) is used as an example of screening designs that would better be used as a wise step before proceeding with detailed factors effects or optimization studies. Five factors probable to affect liposomal systems of weakly basic drugs were investigated using Amisulpride as a model drug. Factors studied were; A: Preparation technique B: Phosphatidyl choline (PhC) amount (mg) C: Cholesterol: PhC molar ratio, D: Hydration volume (ml) and E: Sonication type. Levels investigated were; Ammonium sulphate-pH gradient technique or Transmembrane zinc chelation-pH gradient technique, 200 or 400 mg, 0 or 0.5, 10 or 20 ml and bath or probe sonication for A, B, C, D and E respectively. Responses measured were Particle size (PS) (nm), Zeta potential (ZP) (mV) and Entrapment efficiency percent (EE%). Ion selective electrode was used as a novel method for measuring unentrapped drug concentration and calculating entrapment efficiency without the need for liposomal separation. Factors mainly affecting the studied responses were Cholesterol: PhC ratio and hydration volume for PS, preparation technique for ZP and preparation technique and hydration volume for EE%. The applied 2 V 5-1 design enabled the use of only 16 trial combinations for screening the influence of five factors on weakly basic drugs liposomal systems. This clarifies the value of the use of screening experiments before extensive investigation of certain factors in detailed optimization studies. Copyright © 2017. Published by Elsevier B.V.

Highlights: • The operating mode of the factory and the power supply streams are presented. • Energetic Analysis of steam turbine power plant of an existing phosphoric acid factory. • Exergetic Analysis of each component of steam turbine power plant and the different heat recovery system. • Energy, exergy efficiency and irreversibility rates for the main components are determined. • The effect of the operating parameters on the plant performance are analyzed. - Abstract: An energetic and exergetic analysis is conducted on a Steam Turbine Power Plant of an existing Phosphoric Acid Factory. The heat recovery systems used in the different parts of the plant are also considered in the study. Mass, energy and exergy balances are established on the main compounds of the plant. A numerical code is established using EES software to perform the calculations required for the thermal and exergy plant analysis considering real variation ranges of the main operating parameters such as pressure, temperature and mass flow rate. The effects of theses parameters on the system performances are investigated. The main sources of irreversibility are the melters, followed by the heat exchangers, the steam turbine generator and the pumps. The maximum energy efficiency is obtained for the blower followed by the heat exchangers, the deaerator and the steam turbine generator. The exergy efficiency obtained for the heat exchanger, the steam turbine generator, the deaerator and the blower are 88%, 74%, 72% and 66% respectively. The effects of High Pressure steam temperature and pressure on the steam turbine generator energy and exergy efficiencies are investigated.

Ultrastructural Characterization of Zika Virus Replication Factories

Mirko Cortese

2017-02-01

Full Text Available Summary: A global concern has emerged with the pandemic spread of Zika virus (ZIKV infections that can cause severe neurological symptoms in adults and newborns. ZIKV is a positive-strand RNA virus replicating in virus-induced membranous replication factories (RFs. Here we used various imaging techniques to investigate the ultrastructural details of ZIKV RFs and their relationship with host cell organelles. Analyses of human hepatic cells and neural progenitor cells infected with ZIKV revealed endoplasmic reticulum (ER membrane invaginations containing pore-like openings toward the cytosol, reminiscent to RFs in Dengue virus-infected cells. Both the MR766 African strain and the H/PF/2013 Asian strain, the latter linked to neurological diseases, induce RFs of similar architecture. Importantly, ZIKV infection causes a drastic reorganization of microtubules and intermediate filaments forming cage-like structures surrounding the viral RF. Consistently, ZIKV replication is suppressed by cytoskeleton-targeting drugs. Thus, ZIKV RFs are tightly linked to rearrangements of the host cell cytoskeleton. : Cortese et al. show that ZIKV infection in both human hepatoma and neuronal progenitor cells induces drastic structural modification of the cellular architecture. Microtubules and intermediate filaments surround the viral replication factory composed of vesicles corresponding to ER membrane invagination toward the ER lumen. Importantly, alteration of microtubule flexibility impairs ZIKV replication. Keywords: Zika virus, flavivirus, human neural progenitor cells, replication factories, replication organelles, microtubules, intermediate filaments, electron microscopy, electron tomography, live-cell imaging

Exposing Dark Sector with Future Z-Factories arXiv

CERN Document Server

Liu, Jia; Wang, Xiao-Ping; Xue, Wei

We investigate the prospects of searching dark sector models via exotic Z-boson decay at future $e^+ e^-$ colliders with Giga Z and Tera Z options. Four general categories of dark sector models: Higgs portal dark matter, vector portal dark matter, inelastic dark matter and axion-like particles, are considered. Focusing on channels motivated by the dark sector models, we carry out a model independent study of the sensitivities of Z-factories in probing exotic decays. The limits on branching ratios of the exotic Z decay are typically $\\mathcal{O} (10^{-6} - 10^{-8.5}) $ for the Giga Z and $\\mathcal{O} (10^{-7.5} - 10^{-11})$ for the Tera Z, and they are compared with the projection for the high luminosity LHC. We demonstrate that future Z-factories can provide its unique and leading sensitivity, and highlight the complementarity with other experiments, including the indirect and direct dark matter search limits, and the existing collider limits. Future Z factories will play a leading role to uncover the hidden ...

Background Governance arrangements include changes in rules or processes that determine authority and accountability for health policies, organisations, commercial products and health professionals, as well as the involvement of stakeholders in decision-making. Changes in governance arrangements can affect health and related goals in numerous ways, generally through changes in authority, accountability, openness, participation and coherence. A broad overview of the findings of systematic reviews can help policymakers, their technical support staff and other stakeholders to identify strategies for addressing problems and improving the governance of their health systems. Objectives To provide an overview of the available evidence from up-to-date systematic reviews about the effects of governance arrangements for health systems in low-income countries. Secondary objectives include identifying needs and priorities for future evaluations and systematic reviews on governance arrangements and informing refinements of the framework for governance arrangements outlined in the overview. Methods We searched Health Systems Evidence in November 2010 and PDQ Evidence up to 17 December 2016 for systematic reviews. We did not apply any date, language or publication status limitations in the searches. We included well-conducted systematic reviews of studies that assessed the effects of governance arrangements on patient outcomes (health and health behaviours), the quality or utilisation of healthcare services, resource use (health expenditures, healthcare provider costs, out-of-pocket payments, cost-effectiveness), healthcare provider outcomes (such as sick leave), or social outcomes (such as poverty, employment) and that were published after April 2005. We excluded reviews with limitations that were important enough to compromise the reliability of the findings of the review. Two overview authors independently screened reviews, extracted data and assessed the certainty of evidence

The Photon Factory currently operates four synchrotron beamlines for protein crystallography and two more beamlines are scheduled to be constructed in the next years. Over the last years these beamlines have been upgraded and equipped with a fully automated beamline control system based on a robotic sample changer. The current system allows for remote operation, controlled from the user's area, of sample mounting, centering and data collection of pre-frozen crystals mounted in Hampton-type cryo-loops on goniometer head. New intuitive graphical user interfaces have been developed so as to control the complete beamline operation. Furthermore, algorithms for automatic sample centering based on pattern matching and X-ray beam scanning are being developed and combined with newly developed diffraction evaluation programs in order to complete entire automation of the data collection.

Testing strong factorial invariance using three-level structural equation modeling

Directory of Open Access Journals (Sweden)

Suzanne eJak

2014-07-01

Full Text Available Within structural equation modeling, the most prevalent model to investigate measurement bias is the multigroup model. Equal factor loadings and intercepts across groups in a multigroup model represent strong factorial invariance (absence of measurement bias across groups. Although this approach is possible in principle, it is hardly practical when the number of groups is large or when the group size is relatively small. Jak, Oort and Dolan (2013 showed how strong factorial invariance across large numbers of groups can be tested in a multilevel structural equation modeling framework, by treating group as a random instead of a fixed variable. In the present study, this model is extended for use with three-level data. The proposed method is illustrated with an investigation of strong factorial invariance across 156 school classes and 50 schools in a Dutch dyscalculia test, using three-level structural equation modeling.

Full Text Available The Chinese government has promulgated a de-capacity policy for economic growth and environmental sustainability, especially for the iron and steel industry. With these policies, this study aimed to monitor the economic activities and evaluate the production conditions of an iron and steel factory based on satellites via Landsat-8 Thermal Infrared Sensor (TIRS data and high-resolution images from January 2013 to October 2017, and propel next economic adjustment and environmental protection. Our methods included the construction of a heat island intensity index for an iron and steel factory (ISHII, a heat island radio index for an iron and steel factory (ISHRI and a dense classifying approach to monitor the spatiotemporal changes of the internal heat field of an iron and steel factory. Additionally, we used GF-2 and Google Earth images to identify the main production area, detect facility changes to a factory that alters its heat field and verify the accuracy of thermal analysis in a specific time span. Finally, these methods were used together to evaluate economic activity. Based on five iron and steel factories in the Beijing-Tianjin-Hebei region, when the ISHII curve is higher than the seasonal changes in a time series, production is normal; otherwise, there is a shut-down or cut-back. In the spatial pattern analyses, the ISHRI is large in normal production and decreases when cut-back or shut-down occurs. The density classifying images and high-resolution images give powerful evidence to the above-mentioned results. Finally, three types of economic activities of normal production, shut-down or cut-back were monitored for these samples. The study provides a new perspective and method for monitoring the economic activity of an iron and steel factory and provides supports for sustainable development in China.

CUKROPROJEKT supervised the building of 2 beet sugar factories in the Chinese People's Republic. Work started in 1954 with preparation of the lay-out and the actual erection of the plant started in 1954. The plants in question were the sugar factories Chiamussy on the river Sungari and Sinjungo (New China) in Kirin, both with a daily capacity of 1000 t. Initial difficulties were overcome, the factories were put into operation in 1955 and the planned output was achieved. CUKROPROJEKT experts acquainted themselves with cane sugar processing and planned a design for a 3000 tons/day sugar factory with departments for production of absolute alcohol, fodder yeast, and solid CO/sub 2/. The factory was built in the Pearl River delta. Building operations started in 1957 and the factory started working in 1959. The planned output was achieved during the 1st campaign, with a peak throughput of 3600 tons/day.

Mobile Multi-System Overview

At the time of this reporting, there are 2,589 rich mobile devices used at JPL, including 1,550 iPhones and 968 Blackberrys. Considering a total JPL population of 5,961 employees, mobile applications have a total addressable market of 43 percent of the employees at JPL, and that number is rising. While it was found that no existing desktop tools can realistically be replaced by a mobile application, there is certainly a need to improve access to these desktop tools. When an alarm occurs and an engineer is away from his desk, a convenient means of accessing relevant data can save an engineer a great deal of time and improve his job efficiency. To identify which data is relevant, an engineer benefits from a succinct overview of the data housed in 13+ tools. This need can be well met by a single, rich, mobile application that provides access to desired data across tools in the ops infrastructure.

System theory in industrial patient monitoring: an overview.

Science.gov (United States)

Baura, G D

2004-01-01

Patient monitoring refers to the continuous observation of repeating events of physiologic function to guide therapy or to monitor the effectiveness of interventions, and is used primarily in the intensive care unit and operating room. Commonly processed signals are the electrocardiogram, intraarterial blood pressure, arterial saturation of oxygen, and cardiac output. To this day, the majority of physiologic waveform processing in patient monitors is conducted using heuristic curve fitting. However in the early 1990s, a few enterprising engineers and physicians began using system theory to improve their core processing. Applications included improvement of signal-to-noise ratio, either due to low signal levels or motion artifact, and improvement in feature detection. The goal of this mini-symposium is to review the early work in this emerging field, which has led to technologic breakthroughs. In this overview talk, the process of system theory algorithm research and development is discussed. Research for industrial monitors involves substantial data collection, with some data used for algorithm training and the remainder used for validation. Once the algorithms are validated, they are translated into detailed specifications. Development then translates these specifications into DSP code. The DSP code is verified and validated per the Good Manufacturing Practices mandated by FDA.

Portable Material Culture and Death Factory Auschwitz

Directory of Open Access Journals (Sweden)

Adrian T. Myers

2007-11-01

Full Text Available Like any other factory, the death factory of Auschwitz consumed primary materials and produced secondary products. Unique to Auschwitz, though, is that the primary material consumed was human life; not just the life of the breathing human body, but also the material possessions associated with that life. The detritus of this most efficient genocide – clothing, jewellery, food, corpses – was appropriated and put to new uses by the SS and the prisoners. Others have recognised the various postwar material cultural outcomes of the camp: the writing, the film, the theatre, the art, the tourism. This article, however, demonstrates that the material culture of Auschwitz is not a phenomenon exclusive to the postwar era. It focuses on the fact that inside the camp during the war, despite the landscape of death and deprivation, intimate interaction between humans and material culture continued.

Prototype studies of a 1 MHz chopper for the KAON Factory

1991-05-01

A 1.025 MHz (≅ 10 6 discrete pulses/s) beam chopper is required for the injection line into the accumulator ring of the KAON Factory at TRIUMF. The beam chopper will create 108 ns gaps in the 1 GeV/c H - beam to allow enough time for the magnetic field to be established in the kicker magnets in each of the 5 rings. The required deflection of 1 mrad can be achieved with a set of plates 5 cm apart in which the product of voltage difference and plate length is 37.7 kV.m. The 'kick' must have a rise and fall time of less than 39 ns and a flat top of 49 ns on alternate pulses. A novel design concept for a 1 MHz chopper has been developed involving an energy storage system where the electric pulses are stored in a large diameter (10 cm) low loss coaxial cable. Measurements on the performance of a high voltage prototype are presented. Results are encouraging and show that this novel design can be implemented successfully for the KAON Factory.

Ultrasound imaging is frequently used in medicine. The quality of ultrasound images is often dependent on the skill of the sonographer. Several researchers have proposed robotic systems to aid in ultrasound image acquisition. In this paper we first provide a short overview of robot-assisted ultrasound imaging (US). We categorize robot-assisted US imaging systems into three approaches: autonomous US imaging, teleoperated US imaging, and human-robot cooperation. For each approach several systems are introduced and briefly discussed. We then describe a compact six degree of freedom parallel mechanism telerobotic system for ultrasound imaging developed by our research team. The long-term goal of this work is to enable remote ultrasound scanning through teleoperation. This parallel mechanism allows for both translation and rotation of an ultrasound probe mounted on the top plate along with force control. Our experimental results confirmed good mechanical system performance with a positioning error of < 1 mm. Phantom experiments by a radiologist showed promising results with good image quality.

Overview study of LNG release prevention and control systems

Energy Technology Data Exchange (ETDEWEB)

Pelto, P.J.; Baker, E.G.; Holter, G.M.; Powers, T.B.

1982-03-01

The liquefied natural gas (LNG) industry employs a variety of release prevention and control techniques to reduce the likelihood and the consequences of accidental LNG releases. A study of the effectiveness of these release prevention and control systems is being performed. Reference descriptions for the basic types of LNG facilities were developed. Then an overview study was performed to identify areas that merit subsequent and more detailed analyses. The specific objectives were to characterize the LNG facilities of interest and their release prevention and control systems, identify possible weak links and research needs, and provide an analytical framework for subsequent detailed analyses. The LNG facilities analyzed include a reference export terminal, marine vessel, import terminal, peakshaving facility, truck tanker, and satellite facility. A reference description for these facilities, a preliminary hazards analysis (PHA), and a list of representative release scenarios are included. The reference facility descriptions outline basic process flows, plant layouts, and safety features. The PHA identifies the important release prevention operations. Representative release scenarios provide a format for discussing potential initiating events, effects of the release prevention and control systems, information needs, and potential design changes. These scenarios range from relatively frequent but low consequence releases to unlikely but large releases and are the principal basis for the next stage of analysis.

This study is related to the energy and exergy analysis of a model sugar factory in Turkey. In this study, energy efficiency issue in food industries are investigated within a general context to provide energy saving by reducing energy – exergy losses in the sugar production process. The aim of this study is to determine the best energy and exergy efficiency with the mass and energy balances according to design parameters for a sugar factory. Energy savings that can be applied in food industries are examined. Appropriate scenarios are prepared, and optimization results are compared. As a result of thermodynamics calculations made according to the 1st and 2nd Laws of Thermodynamics, energy and exergy efficiencies of a factory were calculated. Factory total energy efficiency and exergy efficiency were found to be 72.2% and 37.4%, respectively, and according to these results, energy quality was found to be 0.64. In conclusion, the current turbine power process energy and exergy efficiencies were 46.4% and 27.7%, respectively, and the optimized turbine power process energy and exergy efficiencies were 48.7% and 31.7%, respectively. This study performs an attitude to the problem of exergy optimization of the turbine power plant. An overall assessment of the energy and exergy efficiency calculations is performed and is focused on how they should be. - Highlights: • The energy and exergy efficiency of a sugar plant depends more on steam than process. • Energy and exergy efficiencies of a factory increase when the turbine power increases, as in a sugar factory. • Statistical analysis demonstrates the precision of data. • Thermoeconomic analysis of the energy and exergy efficiency of the Çumra Sugar Integrated Plant is performed.

Vertical Integration in factories using OPC-UA and IEC-61499

Directory of Open Access Journals (Sweden)

Marcelo V. García

2017-02-01

Full Text Available Nowadays, factory automation systems need to cope with very different challenges, such as big data, IIoT, etc. These challenges lead to a new generation of automation systems based on the so-called Cyber-Physical Production Systems (CPPS globally connected to form a flexible System of Cyber-Physical Production Systems (SoCPPS. CPPSs require acquisition of production system data and smart data processing to extract information to improve the overall system performance. To achieve that it is needed to bridge the gap between the control systems and higher layers. This paper discusses an approach to use the IEC 61499 function block concept to exchange data between plant floor and higher layers using an industrial standard like OPC UA. The OPC UA server offers subscription mechanisms, making possible the integration of several resources residing at plant floor. As it runs on embedded devices, the proposal makes possible to acquire plant information at low cost, enabling at the same time, a component-based design for enterprise plant floor control with independence of the hardware platform used

1988-03-01

Over the last year considerable progress has been achieved on both technical and political fronts. Hardware studies have continued on both magnet power supplies and on rf cavities - the latter work gaining an extra dimension from a recently-instituted formal collaboration with LAMPF. A racetrack-shaped lattice is being considered in conjunction with a three-element slow extraction system in an effort to reduce losses to the 0.1% level. British Columbia has agreed to fund the buildings and tunnels (Cdn $87M) and is making the KAON Factory its tope priority project with the Canadian federal government. A joint federal-provincial delegation has traveled abroad and found that a number of countries would consider significant contributions to the cost. Government approval contingent upon such contributions is anticipated later in 1988, together with preconstruction R and D funds

The physical meaning and the combinatorial implications of the factorial cumulant of a state variable such as the number of neutrons or the number of neutron counts are specified. Features of the presentation are: (1) the fission process is treated in its entirety without the customary binary emission restriction, (b) the introduction of the factorial cumulants helps in reducing the complexity of the mathematical problems, (c) all the solutions can be obtained analytically. Only the ergodic hypothesis for the neutron population evolution is dealt with. (author)

Burman, Jeremy Trevelyan

2012-08-01

In this article, I use a new book about Jean Piaget to introduce a new historical method: examining "psychological factories." I also discuss some of the ways that "Great Men" are presented in the literature, as well as opportunities for new projects if one approaches the history of the discipline differently and examines the conditions that made that greatness possible. To that end, the article includes many details about Piaget that have never before been discussed in English. Attention is drawn, in particular, to Piaget's collaborators: the hundreds of workers at his factory in Geneva, many of whom were women. (PsycINFO Database Record (c) 2012 APA, all rights reserved).

The main focus in development of yeast cell factories has generally been on establishing optimal activity of heterologous pathways and further metabolic engineering of the host strain to maximize product yield and titer. Adequate stress tolerance of the host strain has turned out to be another major challenge for obtaining economically viable performance in industrial production. Although general robustness is a universal requirement for industrial microorganisms, production of novel compounds using artificial metabolic pathways presents additional challenges. Many of the bio-based compounds desirable for production by cell factories are highly toxic to the host cells in the titers required for economic viability. Artificial metabolic pathways also turn out to be much more sensitive to stress factors than endogenous pathways, likely because regulation of the latter has been optimized in evolution in myriads of environmental conditions. We discuss different environmental and metabolic stress factors with high relevance for industrial utilization of yeast cell factories and the experimental approaches used to engineer higher stress tolerance. Improving stress tolerance in a predictable manner in yeast cell factories should facilitate their widespread utilization in the bio-based economy and extend the range of products successfully produced in large scale in a sustainable and economically profitable way. © FEMS 2017.

Methods of factorial moments and fractal dimensions are used to analyze γ families from nuclear-electromagnetic cascades in the atmosphere. The analysis aims at estimating the sensitivity of these methods to multiparticle density fluctuations in γ families as considered in spaces of various variables. The mean characteristics of factorial and fractal moments in the azimuthal plane are studied and compared with those of the statistical ensemble of random families. It is shown that fluctuations of the photon distribution in the azimuthal angle Φ are of a dynamic origin. The mean model parameters are analyzed as functions of the radius vector R, an analog of pseudorapidity, and the product ER (E is the energy of an individual photon), an analog of the transverse momentum. Particle densities for two-dimensional partitions into both rings (in the radius R) and sectors (in the azimuthal angle Φ), d 2 N/dΦdR, are also considered. The distributions of various factorial and fractal features of individual γ families are compared with those for the statistical ensemble of random families. Correlations of these features for a γ family treated in terms of different variables (sectors and rings) are studied. Correlations between different factorial-fractal parameters of γ families are analyzed

The consumption of soft-drinks has been associated with dental caries development. The aim was to evaluate dental caries experience amongst the workers working in soft-drink industries located in South India and compare it with other factory workers. To evaluate the validity of specific caries index (SCI), which is newer index for caries diagnosis. This was a cross-sectional study carried out among 420 workers (210 in soft-drinks factory and 210 in other factories), in the age group of 20-45 years of Udupi district, Karnataka, India. Index used for clinical examination was decayed, missing, filled surfaces (DMFS) index and SCI. The mean and standard deviation (SD) of decayed surface (5.8 ± 1.8), missing surface (4.3 ± 2) and filled surface (1.94 ± 1.95) and total DMFS score (12.11 ± 3.8) in soft-drinks factory workers were found to be significantly higher than the other factory workers. The total SCI score (mean and SD) was found to be significantly higher in soft-drinks factory workers (5.83 ± 1.80) compared with other factory workers (4.56 ± 1.45). There was a high correlation obtained between SCI score and DMFS score. The regression equation given by DMFS = 1.178 + 1.866 (SCI scores). The caries experience was higher in workers working in soft-drinks factory and this study also showed that specific caries index can be used as a valid index for assessing dental caries experience.
