    The objective of this advanced technology development (ATD) project has been to provide sturdy, miniaturized laser light scattering (LLS) instrumentation for use in microgravity experiments. To do this, we assessed user requirements, explored the capabilities of existing and prospective laser light scattering hardware, and both coordinated and participated in the hardware and software advances needed for a flight hardware instrument. We have successfully breadboarded and evaluated an engineering version of a single-angle glove-box instrument which uses solid state detectors and lasers, along with fiber optics, for beam delivery and detection. Additionally, we have provided the specifications and written verification procedures necessary for procuring a miniature multi-angle LLS instrument which will be used by the flight hardware project which resulted from this work and from this project's interaction with the laser light scattering community.

    Entering the 1990s, technological tools that were in the research and development stage not so long ago are changing the way inspectors are able to verify nuclear materials at many facilities around the world. Many new instruments - ranging from advanced video monitoring systems to miniature detectors and analysers - already are in place. In some cases, they have been custom-made for specific safeguards tasks, or for placement in locations, such as underwater storage pools for spent reactor fuel, where inspectors cannot go. Standing behind the development of many of these new safeguards instruments are a number of factors. They include: technological advances In computer related fields, such as microprocessing and electronics, and specific areas of instrumentation; technical developments in the nuclear industry and Efficiency improvements and efforts to reduce the costs of safeguards implementation

    In public debates about German industry's global competitiveness it becomes evident that environmental law and the technology-related law are almost exclusively perceived as systems of law which - for reasons of environmental protection and protection of public health - are setting restraints to technological development. This is a narrow perspective neglecting the functions of the law as an instrument providing legal security and a reliable framework for developments. In a democratic, constitutional state, the environmental law and the technology-related law are instruments providing for protection of the basic, general rights and requirements of technology, and contribute to ensuring general acceptance of technologic development.

    In this report automatic startup technology and dynamic alarm processing technology are developed. We designed an automatic control system had four modes and six break points. The four modes are heating mode I, heating mode II, heating mode III and critical mode. The six break points are RHR isolation and pressurizer bubble generation, P-6, critical conformation and another three break points for the start point of each mode from heating mode II to critical mode. We defined control variables and components at each mode and developed control algorithms. The conceptual design for automatic startup system configuration and interface with test facility was developed. These results will be used for detail design and software implementation in the project of next year. For development of dynamic alarm processing technology, necessary techniques were selected according to the survey on current development activities and the analysis on design documents. Alarm operating procedures were studied for obtaining casual relationships among alarms and part of a preliminary prototype was implemented in this first year using the results of the analysis including various techniques studied during the survey and analysis stage. 70 figs, 7 tabs, 77 refs.

    The science objectives for proposed NASA missions for the next decades push the state of the art in sensitivity and spatial resolution over a wide range of wavelengths, including the x-ray to the submillimeter. While some of the proposed missions are larger and more sensitive versions of familiar concepts, such as the next generation space telescope, others use concepts, common on the Earth, but new to space, such as optical interferometry, in order to provide spatial resolutions impossible with other concepts. However, despite their architecture, the performance of all of the proposed missions depends critically on the back-end instruments that process the collected energy to produce scientifically interesting outputs. The Advanced Optical Instruments Technology panel was chartered with defining technology development plans that would best improve optical instrument performance for future astrophysics missions. At this workshop the optical instrument was defined as the set of optical components that reimage the light from the telescope onto the detectors to provide information about the spatial, spectral, and polarization properties of the light. This definition was used to distinguish the optical instrument technology issues from those associated with the telescope, which were covered by a separate panel. The panel identified several areas for optical component technology development: diffraction gratings; tunable filters; interferometric beam combiners; optical materials; and fiber optics. The panel also determined that stray light suppression instruments, such as coronagraphs and nulling interferometers, were in need of general development to support future astrophysics needs.

    Instrumentation is developed for the Civilian Radioactive Waste Management Program to meet several different (and sometimes conflicting) objectives. This paper addresses instrumentation development for data needs that are related either directly or indirectly to a repository site, but does not touch on instrumentation for work with waste forms or other materials. Consequently, this implies a relatively large scale for the measurements, and an in situ setting for instrument performance. In this context, instruments are needed for site characterization to define phenomena, develop models, and obtain parameter values, and for later design and performance confirmation testing in the constructed repository. The former set of applications is more immediate, and is driven by the needs of program design and performance assessment activities. A host of general technical and nontechnical issues have arisen to challenge instrumentation development. Instruments can be classed into geomechanical, geohydrologic, or other specialty categories, but these issues cut across artificial classifications. These issues are outlined. Despite this imposing list of issues, several case histories are cited to evaluate progress in the area

    Background:The nature of technology has been rarely discussed despite the fact that technology plays an essential role in modern society. It is important to discuss students' concepts of the nature of technology, and further to advance their technological literacy and adaptation to modern society. There is a need to assess high school students' concepts of the nature of technology. Purpose:This study aims to engage in discourse on students' concepts of the nature of technology based on a proposed theoretical framework. Moreover, another goal is to develop an instrument for measuring students' concepts of the nature of technology. Sample:Four hundred and fifty-five high school students' perceptions of technology were qualitatively analyzed. Furthermore, 530 students' responses to a newly developed questionnaire were quantitatively analyzed in the final test. Design and method:First, content analysis was utilized to discuss and categorize students' statements regarding technology and its related issues. The Student Concepts of the Nature of Technology Questionnaire was developed based on the proposed theoretical framework and was supported by the students' qualitative data. Finally, exploratory factor analysis and reliability analysis were applied to determine the structure of the items and the internal consistency of each scale. Results:Through a process of instrument development, the Student Concepts of the Nature of Technology Questionnaire was shown to be a valid and reliable tool for measuring students' concepts of the nature of technology. This newly developed questionnaire is composed of 29 items in six scales, namely 'technology as artifacts,' 'technology as an innovation change,' 'the current role of technology in society,' 'technology as a double-edged sword,' 'technology as a science-based form,' and 'history of technology.' Conclusions:The Student Concepts of the Nature of Technology Questionnaire has been confirmed as a reasonably valid and reliable

    Although several organizations are performing their tasks making efforts to develop new digital technology for application to existing nuclear power plants as well as new plants of the future, their projects are similar to each other and have possibilities of redundant investment. Therefore, KAERI have established a Master Plan to define the suitable work-scope of each Instrumentation and Control (I and C) development project and proceed its development items continuously. Furthermore, in the project, several kinds of advanced technology for application of computer science and digital electronics were studied to obtain better reliability of the I and C systems and reduce opertor's burden. For establishing the Master Plan, functions of I and C system of NPPs were surveyed. Especially EPRI URD was deeply analyzed for setting up a basis of the foreign countries were referred for the Master Plan. For the new technology survey, fault-tolerant control technology and control system performance analysis methods were studied. Requirements of alarm and information system as well as technology of I and C network system of NPPs were also established to introduce the advantages of commercial distributed control system.

    Technology-based aids for lifestyle change are becoming more prevalent for chronic conditions. Important "digital divides" remain, as well as concerns about privacy, data security, and lack of motivation. Researchers need a way to characterize participants' readiness to use health technologies. To address this need, we created an instrument to measure patient readiness to engage with health technologies among adult patients with chronic conditions. Initial focus groups to determine domains, followed by item development and refinement, and exploratory factor analysis to determine final items and factor structure. The development sample included 200 patients with chronic conditions from 6 family medicine clinics. From 98 potential items, 53 best candidate items were examined using exploratory factor analysis. Pearson's Correlation for Test/Retest reliability at 3 months. The final instrument had 28 items that sorted into 8 factors with associated Cronbach's alpha: 1) Health Information Need (0.84), 2) Computer/Internet Experience (0.87), 3) Computer Anxiety (0.82), 4) Preferred Mode of Interaction (0.73), 5) Relationship with Doctor (0.65), 6) Cell Phone Expertise (0.75), 7) Internet Privacy (0.71), and 8) No News is Good News (0.57). Test-retest reliability for the 8 subscales ranged from (0.60 to 0.85). The Patient Readiness to Engage in Health Internet Technology (PRE-HIT) instrument has good psychometric properties and will be an aid to researchers investigating technology-based health interventions. Future work will examine predictive validity.

    It is necessary to develop various types of welding, instrumentation and helium gas filling techniques that can conduct TIG spot welding exactly at a pin-hole of the end-cap on the nuclear fuel rod to fill up helium gas. The welding process is one of the most important among the instrumentation processes of the nuclear fuel test rod. To manufacture the nuclear fuel test rod, a precision welding system needs to be fabricated to develop various welding technologies of the fuel test rod jointing the various sensors and end-caps on a fuel cladding tube, which is charged with fuel pellets and component parts. We therefore designed and fabricated an orbital TIG welding system and a laser welding system. This paper describes not only some experiment results from weld tests for the parts of a nuclear fuel test rod, but also the contents for the instrumentation process of the dummy fuel test rod installed with the C-type T. C. A dummy nuclear fuel test rod was successfully fabricated with the welding and instrumentation technologies acquired with various tests. In the test results, the round welding has shown a good weldability at both the orbital TIG welding system and the fiber laser welding system. The spot welding to fill up helium gas has shown a good welding performance at a welding current of 30A, welding time of 0.4 sec and gap of 1 mm in a helium gas atmosphere. The soundness of the nuclear fuel test rod sealed by a mechanical sealing method was confirmed by helium leak tests and microstructural analyses

    Instrumentation, controls, and human-machine interfaces are essential enabling technologies that strongly influence nuclear power plant performance and operational costs. The nuclear power industry is currently engaged in a transition from traditional analog-based instrumentation, controls, and human-machine interface (ICHMI) systems to implementations employing digital technologies. This transition has primarily occurred in an ad hoc fashion through individual system upgrades at existing plants and has been constrained by a number of concerns. Although international implementation of evolutionary nuclear power plants and the progression toward new plants in the United States have spurred design of more fully digital plant-wide ICHMI systems, the experience base in the nuclear power application domain is limited. Additionally, design and development programs by the U.S. Department of Energy (DOE) for advanced reactor concepts, such as the Generation IV Program and Next Generation Nuclear Plant (NGNP), introduce different plant conditions and unique plant configurations that increase the need for enhanced ICHMI capabilities to fully achieve programmatic goals related to economic competitiveness, safety and reliability, sustainability, and proliferation resistance and physical protection. As a result, there are challenges that need to be addressed to enable the nuclear power industry to effectively and efficiently complete the transition to safe and comprehensive use of digital technology

    All of the nuclear power plants in Korea are operating with analog instrumentation and control (I and C) equipment which are increasingly faced with frequent troubles, obsolescence and high maintenance expense. Electrical and computer technology has improved rapidly in recent years and has been applied to other industries. So it is strongly recommended to adopt the modern digital and computer technology to improve plant safety and availability. The plan, which is aimed at replacement of existing I and C systems, and at improving planned as well as next generation digital I and C systems is divided into three major parts: (1) Plan for domestic design of I and C systems and components, (2) Plan for domestic manufacturing of I and C equipment, and (3) Plan for development of future technologies. This plan provides advanced digital I and C requirements equivalent to Electric Power Research Institute Utility Requirements Document (Chapter 10) Man Machine Interface Systems. Also this plan includes the critical issue of digital I and C, namely software verification and validation strategy. (6 refs., 1 fig., 2 tabs.)

  7. On the selection of financing instruments to push the development of new technologies: Application to clean energy technologies

    2012-01-01

    Achieving climate policy goals requires mobilizing public funds to bring still immature clean technologies to competitiveness and create new technological options. The format of direct public support must be tailored to the characteristics of technologies addressed. Based on the experience accumulated with innovation programs, we have identified those features of innovation that should directly condition the choice of direct support instruments. These include the funding gap between the cost of innovation activities and the amount of private funds leveraged; the ability of technologies targeted to compete for public funds in the market; the probability that these technologies fail to reach the market; and the type of entity best suited to conduct these activities. Clean innovation features are matched to those of direct support instruments to provide recommendations on the use to be made of each type of instrument. Given the large financing gap of most clean energy innovation projects, public grants and contracts should finance a large part of clean pre-deployment innovation. However, public loans, equity investments, prizes and tax credits or rebates can successfully support certain innovation processes at a lower public cost. Principles derived are applied to identify the instrument best suited to a case example. - Highlights: ► Public financing instruments must be tailored to the features of supported innovation. ► Instruments should trigger desired innovation at the lowest public cost possible. ► They should strike the right balance between technology selection and competition. ► Public funds mobilized through them should reach the innovating entity. ► Public loans, equity investments, prizes, and rebates should be used in specific cases.

In the DSP part, the DSP requirements for NPPs have been induced for the performance of the DSP systems and the functional analysis for Reactor Coolant System (RCS) has been performed as the embodied target system. Total quantities of the I and C signals, signal types, and signal functions were also investigated in Ulchin NPP units 3 and 4. From these basis, the prototype facility was configured for performance validation and algorithm implementation. In order to develop the methods of DSP techniques and algorithms, the current signal validation methods have been studied and analyzed. In the analysis for the communication networks in NPP, the basic technique for the configuration of communication networks and the important considerations for applying to NPPs have been reviewed. Test and experimental facilities have been set up in order to carry out the required tests during research activities on the monitoring techniques for abnormal conditions. Studies were concentrated on methods how to acquire vibration signals from the mechanical structures and equipment including rotating machinery and reactor, and analyses for the characteristics of the signals. Fuzzy logic was evaluated as a good technique to improve the reliability of the monitoring and diagnosing algorithm through the application of the theory such as the automatic pattern recognition algorithm of the vibration spectrum, the alarm detection and diagnosis for collisions of loose parts. 71 figs, 32 tabs, 64 refs.

    We found essential problems followed by digitalizing of instrumentation and control. A scheme is divided into hardware and software to resolve these problems. We have analyzed the hardware V and V methodologies about common mode failure, commercial grade dedication process and electromagnetic compatibility. We have developed several guidelines, the software classification guideline, the quality assurance handbook for the software in digital I and C, the software V and V planning guideline, and the software safety guideline. And then, we have established the integrated environment for the safety-critical software based on the Computer Aided Software Engineering (CASE) tools. We have also surveyed a trend and application case of test facility for establishment of functional requirements. Input/output interface which connects among the host computer and developed target and panel are designed and manufactured using UXI bus. The developed functional test facility is used for test and validate the automatic start-up intelligent control system, the dynamic alarm system, the accident identification system using hidden Markov model, and the intelligent logic tracking system.

    Instrumented roll technology on Alexanderwerk WP120 roller compactor was developed and utilized successfully for the measurement of normal stress on ribbon during the process. The effects of process parameters such as roll speed (4-12 rpm), feed screw speed (19-53 rpm), and hydraulic roll pressure (40-70 bar) on normal stress and ribbon density were studied using placebo and active pre-blends. The placebo blend consisted of 1:1 ratio of microcrystalline cellulose PH102 and anhydrous lactose with sodium croscarmellose, colloidal silicon dioxide, and magnesium stearate. The active pre-blends were prepared using various combinations of one active ingredient (3-17%, w/w) and lubricant (0.1-0.9%, w/w) levels with remaining excipients same as placebo. Three force transducers (load cells) were installed linearly along the width of the roll, equidistant from each other with one transducer located in the center. Normal stress values recorded by side sensors and were lower than normal stress values recorded by middle sensor and showed greater variability than middle sensor. Normal stress was found to be directly proportional to hydraulic pressure and inversely to screw to roll speed ratio. For active pre-blends, normal stress was also a function of compressibility. For placebo pre-blends, ribbon density increased as normal stress increased. For active pre-blends, in addition to normal stress, ribbon density was also a function of gap. Models developed using placebo were found to predict ribbon densities of active blends with good accuracy and the prediction error decreased as the drug concentration of active blend decreased. Effective angle of internal friction and compressibility properties of active pre blend may be used as key indicators for predicting ribbon densities of active blend using placebo ribbon density model. Feasibility of on-line prediction of ribbon density during roller compaction was demonstrated using porosity-pressure data of pre-blend and normal stress

    Full Text Available The increased use of technology within the educational field gives rise to the need for developing valid instruments to measure key constructs associated with performance. We present some self-report instruments developed and/or validated in the Italian context that could be used to assess achievement emotions and correlates, within the theoretical framework of Pekrun’s control-value model. First, we propose some data related to the construction of two instruments developed to assess ten achievement emotions: the Brief Achievement Emotions Questionnaire, BR-AEQ, used with college students, and the Graduated Achievement Emotions Set, GR-AES, used with primary school students. Second, we describe some data concerning the validation within the Italian context of two instruments assessing achievement goals as antecedents of achievement emotions: the Achievement Goal Questionnaire-Revised, AGQ-R, and its more recent version based on the 3 X 2 achievement goal model.

    This project is currently engaging twelve undergraduate students in the process of developing new technology and instrumentation for use in balloon borne geospace investigations in the auroral zone. Motivation stems from advances in microelectronics and consumer electronic technology. Given the technological innovations over the past 20 years it now possible to develop new instrumentation to study the auroral ionosphere and stratospheric ozone layer using ultralight balloon payloads for less than 6lbs and $3K per payload. The University of Houston Undergraduate Student Instrumentation Project (USIP) team has built ten such payloads for launch using 1500 gm latex weather balloons deployed in Houston, TX, Fairbanks, AK, and as well as zero pressure balloons launched from northern Sweden. The latex balloon project will collect vertical profiles of wind velocity, temperature, electrical conductivity, ozone, and odd nitrogen. This instrument payload will also produce profiles of pressure, electric field, and air-earth electric current. The zero pressure balloons will obtain a suite of geophysical measurements including: DC electric field, electric field and magnetic flux, optical imaging, total electron content of ionosphere via dual-channel GPS, X-ray detection, and infrared/UV spectroscopy. Students flew payloads with different combinations of these instruments to determine which packages are successful. Data collected by these instruments will be useful in understanding the nature of electrodynamic coupling in the upper atmosphere and how the global earth system is changing. Twelve out of the launched fifteen payloads were successfully launched and recovered. Results and best practices learned from lab tests and initial Houston test flights will be discussed.

    Zircaloy-4 of the nuclear fuel test rod, AISI 316L of the mechanical sealing parts, and the MI (mineral insulated) cable at a thermocouple instrumentation are hetero-metals, and are difficult to weld to dissimilar materials. Therefore, a mechanical sealing method to instrument the thermocouple should be conducted using two kinds of sealing process as follows: One is a mechanical sealing process using Swagelok, which is composed of sealing components that consists of an end-cap, a seal tube, a compression ring and a Swagelok nut. The other is a laser welding process used to join a seal tube, and an MI cable, which are made of the same material. The mechanical sealing process should be sealed up with the mechanical contact compressed by the strength forced between a seal tube and an end-cap, and the laser welding process should be conducted to have no defects on the sealing area between a seal tube and an MI cable. Therefore, the mechanical sealing and laser welding techniques need to be developed to accurately measure the centerline temperature of the nuclear fuel test rod in an experimental reactor. The mechanical sealing and laser welding tests were conducted to develop the thermocouple instrumentation techniques for the nuclear fuel test rod. The optimum torque value of a Swagelok nut to seal the mechanical sealing part between the end-cap and seal tube was established through various torque tests using a torque wrench. The optimum laser welding conditions to seal the welding part between a seal tube and an MI cable were obtained through various welding tests using a laser welding system

    The irradiation test of end-plug specimens was planned for the evaluation of nuclear fuels performance. To establish the fabrication process, and for satisfying the requirements of the irradiation test, an orbital-GTA weld machine for the specimens of the dual rods was developed, and the preliminary welding experiments for optimizing the process conditions of the specimens of the dual rods were performed. Dual rods with a 9.5mm diameter and a 0.6mm wall thickness of the cladding tubes and end-plugs have been used and the optimum conditions of the pin-hole welding have also been selected. This paper describes the experimental results of the GTA welds of the specimens of the dual rods and the metallography examinations of the GTA welded specimens for various welding conditions for the instrumented fuel irradiation test. These investigations satisfied the requirements of the instrumented irradiation test and the GTA welds for the specimens of the dual rods at the HANARO research reactor

    The phenomenon of "digital divide" is complex and multidimensional, extending beyond issues of physical access. The purpose of this study was to develop a scale to measure a range of factors related to digital divide among higher education faculty and to evaluate its reliability and validity. Faculty's Information and Communication Technology Access (FICTA) scale was tested and validated with 322 faculty teaching in public and private sector universities. Principal components analysis with varimax rotation confirmed an 8-factor solution corresponding to various dimensions of ICT access. The 57-item FICTA scale demonstrated good psychometric properties and offers researchers a tool to examine faculty's access to ICT at four levels - motivational, physical, skills, and usage access.

    The PWR plant operation is normally categorized into plant startup, low power operation, normal operation, cooldown operation. In these operation, however, startup and cooldown operation is performed manually according to the operation procedure. These manual operation is required to operator`s technical skills. And the manual operation can be occurred to operational errors because of operator`s workload during long duration. Automatic startup system, named by Automatic Startup Intelligent Control System (ASICS) is developed for reducing operator tasks, optimizing heatup operation, and enhancement of operation reliability and availability from cold shutdown to reactor power 5%. ADIOS has applied several alarm processing technologies, such as plant mode dependency, state dependence, direct precursor, and level precursor, etc. ADIOS has also applied a model-base diagnostic functions for operator to cope with major transients. To confirm a correctness of alarm processing techniques, prototype have been developed based on KORI 3 and YGN 3 PWR NPPs. The about 3000 alarm objects have been represented as knowledge base in the prototypes. The alarm window like tile for the safety-related alarms, primary and secondary schematic display, and detailed system-level schematic display have been designed.

    Body posture and activity are important indices for assessing health and quality of life, especially for elderly people. Therefore, an easily wearable device or instrumented garment would be valuable for monitoring elderly people’s postures and activities to facilitate healthy aging. In particular, such devices should be accepted by elderly people so that they are willing to wear it all the time. This paper presents the design and development of a novel, textile-based, intelligent wearable vest for real-time posture monitoring and emergency warnings. The vest provides a highly portable and low-cost solution that can be used both indoors and outdoors in order to provide long-term care at home, including health promotion, healthy aging assessments, and health abnormality alerts. The usability of the system was verified using a technology acceptance model-based study of 50 elderly people. The results indicated that although elderly people are anxious about some newly developed wearable technologies, they look forward to wearing this instrumented posture-monitoring vest in the future.

    WEAVE is the next-generation wide-field optical spectroscopy facility for the William Herschel Telescope (WHT) on La Palma in the Canary Islands, Spain. It is a multi-object "pick-and-place" fibre-fed spectrograph with a 1000 fibre multiplex behind a new dedicated 2° prime focus corrector. The WEAVE positioner concept uses two robots working in tandem in order to reconfigure a fully populated field within the expected 1 hour dwell-time for the instrument (a good match between the required exposure times and the limit of validity for a given configuration due to the effects of differential refraction). In this paper we describe some of the final design decisions arising from the prototyping phase of the instrument design and provide an update on the current manufacturing status of the fibre positioner system.

  11. Developments in analytical instrumentation

    Science.gov (United States)

    Petrie, G.

    The situation regarding photogrammetric instrumentation has changed quite dramatically over the last 2 or 3 years with the withdrawal of most analogue stereo-plotting machines from the market place and their replacement by analytically based instrumentation. While there have been few new developments in the field of comparators, there has been an explosive development in the area of small, relatively inexpensive analytical stereo-plotters based on the use of microcomputers. In particular, a number of new instruments have been introduced by manufacturers who mostly have not been associated previously with photogrammetry. Several innovative concepts have been introduced in these small but capable instruments, many of which are aimed at specialised applications, e.g. in close-range photogrammetry (using small-format cameras); for thematic mapping (by organisations engaged in environmental monitoring or resources exploitation); for map revision, etc. Another innovative and possibly significant development has been the production of conversion kits to convert suitable analogue stereo-plotting machines such as the Topocart, PG-2 and B-8 into fully fledged analytical plotters. The larger and more sophisticated analytical stereo-plotters are mostly being produced by the traditional mainstream photogrammetric systems suppliers with several new instruments and developments being introduced at the top end of the market. These include the use of enlarged photo stages to handle images up to 25 × 50 cm format; the complete integration of graphics workstations into the analytical plotter design; the introduction of graphics superimposition and stereo-superimposition; the addition of correlators for the automatic measurement of height, etc. The software associated with this new analytical instrumentation is now undergoing extensive re-development with the need to supply photogrammetric data as input to the more sophisticated G.I.S. systems now being installed by clients, instead

  12. Technological considerations in emergency instrument preparedness

    Emergency preparedness has been emphasized during the development of the nuclear industry. Existing instrumentation technology has been effectively applied to minimizing the probability of accidents. Radiological instrumentation provided for the measurement of ambient radiation levels or routine releases of radioactive material is usually adequate to provide an early warning that an accident is occurring. In contrast, radiological instrumentation capable of providing a reasonable measure of the source term which could be involved in a severe accident has not received enough attention. In emergency planning the capability should be established for identifying as promptly as possible the need for evasive action out in the plant environs and for minimizing the consequences of an accident in terms of resultant human exposure. Therefore instrumentation is required to measure the source term no matter where the point of release might be, together with instrumentation for obtaining meteorological data sufficient to establish the path of the release in the environment

    Full text : Nuclear Instrumentation is a field of vital importance for DAE. It has important applications in many areas of interest such as Reactor Monitoring and control, Accelerator based research, Laser and nuclear physics experiments, Health and environmental monitoring, Astrophysics experiments etc. It is a specialized field involving expertise in detection of radioactivity down to the level of few events per minute as well as processing and analysis of signals which can be as small as few hundred micro volts embedded in noise. Some applications involve digitizing and processing these signals with 0.001% accuracy and timing accuracies of a fraction of nano sec. Rapid developments in semiconductor related technologies have influenced the field of nuclear instrumentation. Development of FPGA's and ASIC's have made it possible to develop miniaturized smart and portable instruments for field applications. Advancements in field of computers, communications and various field buses have been successfully utilized for smart, portable and DSP based instrumentation. Smart sensor with detector and front-end electronics on a single silicon chip is now a reality. These instruments are also made intelligent by addition of fuzzy logic, artificial neural networks and expert systems. Electronics Division of BARC has made significant contribution to the field of nuclear instrumentation to achieve self-reliance in this area. This has also led to development of several new methods, which have been published in international journals and appreciated worldwide. As a step towards achieving complete self-reliance a programme for development of FPGA's, HMC's and ASIC's has been undertaken and is being followed with special emphasis. This also includes development of detector and front- end electronics on a single chip. This talk brings out details of these developments and describes the 'state of art' work done in India

    A general nuclear power stations desire to continue operating for as long as possible. But, cable in nuclear power stations can be subjected to energetic radiation to various degrees as well as other environmental stimuli. It is of major importance to know how these materials will respond and how any resulting aging phenomena can be monitored. From the point of view of nuclear safety the interest in these cables derives from the fact that they are of vital importance. Many researches on cable condition monitoring have been conducting for many years and various techniques of condition monitoring have been suggested until now. We will develop the combination of CM methods using merits of preliminary methods and CM methods using signal processing technique.

    1995-01-01

    Nuclear components, nuclear practices and nuclear facilities have all improved with the maturing of the industry. These improvements have been driven by forces, which are beyond the normal evolutionary pressures, such as increased safety, as low as possible radiation exposure for the workers as well as for the public and the increasing competiveness of alternative forms of energy generation. International nuclear safeguards has had to keep pace with these technological and administrative changes. Moreover, the political climate has changed since the initial implementation of safeguards under the Non-Proliferation Treaty. Implementation of safeguards agreements has accommodated to these changes as well as to the technical innovations. One important component of safeguards implementation, namely the instruments deployed by inspectors, has matured with the help of Member States. Continued efforts in the development and deployment of appropriate instruments are needed to maintain an acceptable level of efficiency and credibility. (orig.)

    A major objective of the project is to develop a digital automatic supervisory limitation system and validate its design for the next generation= nuclear power plant. The limitation system assures that the plant does not exceed the operating limits by regulation the plant operations through on-line monitoring the operating margins of the critical parameters. A new conceptual model of power maneuverability has been proposed for the design of the limitation system and for its validation. Also, the limitation system monitors overall operation processes throughout a nuclear power plant by implementing hierarchical communication networks. Based on the conceptual design in software of the 1 st year results, the detailed design of the limitation system has been performed during the 2 nd year with constructing a prototype digital system. The system consists of the software module for plant simulation and the hardware module for implementation of limitation system and the associated interfaces in hardware. The limitation algorithm were implemented into the microprocessor and the interfaces were realized through the I/O modules. Also, these modules are incorporated into the communication networks. The products of the project could be directly applicable to the following nuclear unit adopting the limitation system, providing the bumpless transition to the commercial design phase. And the prototype evaluation scheme will be very useful for the succeeding studies related to the digital nuclear I and C fields, such as fault-tolerance design methods, software verification and validation and response time execution of digital systems. 69 refs., 3 tabs., 44 figs.

    Resilience benefits from the use of protective factors, as opposed to risk factors, which are associated with vulnerability. Considerable research and instrument development has been conducted in clinical settings for patients. The need existed for an instrument to be developed in a workplace setting to measure resilience of employees. This study developed and tested a resilience instrument for employees in the workplace. The research instrument was distributed to executives and nurses working in the United States in hospital settings. Five-hundred-forty completed and usable responses were obtained. The instrument contained an inventory of workplace resilience, a job stress questionnaire, and relevant demographics. The resilience items were written based on previous work by the lead author and inspired by Weick's [1] sense-making theory. A four-factor model yielded an instrument having psychometric properties showing good model fit. Twenty items were retained for the resulting Workplace Resilience Instrument (WRI). Parallel analysis was conducted with successive iterations of exploratory and confirmatory factor analyses. Respondents were classified based on their employment with either a rural or an urban hospital. Executives had significantly higher WRI scores than nurses, controlling for gender. WRI scores were positively and significantly correlated with years of experience and the Brief Job Stress Questionnaire. An instrument to measure individual resilience in the workplace (WRI) was developed. The WRI's four factors identify dimensions of workplace resilience for use in subsequent investigations: Active Problem-Solving, Team Efficacy, Confident Sense-Making, and Bricolage.

    Laparoscopy was a progressive step to advancing surgical procedures as it minimised the scars left on the body after surgery, compared to traditional open surgery. Many years later, single-incision laparoscopic surgery (SILS) was created where, instead of having multiple incisions, only one incision is made or multiple small incisions in one location. SILS, or laparoendoscopic single-site surgery (LESS), may produce lesser scars but drawbacks for the surgeons are still present. This paper aims to present related literature of the recent technological developments in laparoscopic tools and procedure particularly in the vision system, handheld instruments. Tech advances in LESS will also be shown. Furthermore, this review intends to give an update on what has been going on in the surgical robot market and state which companies are interested and are developing robotic systems for commercial use to challenge Intuitive Surgical's da Vinci Surgical System that currently dominates the market.

    This white paper offers cautionary observations about the planning and development of new, large radio astronomy instruments. Complexity is a strong cost driver so every effort should be made to assign differing science requirements to different instruments and probably different sites. The appeal of shared resources is generally not realized in practice and can often be counterproductive. Instrument optimization is much more difficult with longer lists of requirements, and the development process is longer and less efficient. More complex instruments are necessarily further behind the technology state of the art because of longer development times. Including technology R&D in the construction phase of projects is a growing trend that leads to higher risks, cost overruns, schedule delays, and project de-scoping. There are no technology breakthroughs just over the horizon that will suddenly bring down the cost of collecting area. Advances come largely through careful attention to detail in the adoption of new technology provided by industry and the commercial market. Radio astronomy instrumentation has a very bright future, but a vigorous long-term R&D program not tied directly to specific projects needs to be restored, fostered, and preserved.

    We have examined requirements for a fusion instrumentation and control development program to determine where emphasis is needed. The complex, fast, and closely coupled system dynamics of fusion reactors reveal a need for a rigorous approach to the development of instrumentation and control systems. A framework for such a development program should concentrate on three principal need areas: the operator-machine interface, the data and control system architecture, and fusion compatible instruments and sensors. System dynamics characterization of the whole fusion reactor system is also needed to facilitate the implementation process in each of these areas. Finally, the future need to make the instrumentation and control system compatible with the requirements of a commercial plant is met by applying transition technology. These needs form the basis for the program tasks suggested

    In the medical diagnosis, the nuclear medical instrument using the radioactive isotope are commonly utilized. In the foreign countries, the medical application and development of the most advanced nuclear medical instrument such as Single Photon Emission Computer Tomography (SPECT) and position emission tomograph (PET), have been extensively carried out. However, in Korea, such highly expensive instruments have been all, imported, paying foreign currency. Since 1997, much efforts, the development of the radio nuclide medical instrument, the drive of the domestic production, etc. have been made to establish our own technologies and to balance the international payments under the support of the Ministry of Science and Technology. At present time, 180 nuclear imaging instruments are now in operation and 60 of them are analog camera. In analog camera, the vector X-Y monitor is need for are image display. Since the analog camera, signal can not be process in the digital form, we have difficulties to transfer and store the image data. The image displayed at the monitor must be stored in the form of polaroid or X ray film. In order to discard these disadvantages, if we developed the computer interface system, the performance analog camera will be comparable with that of the digital camera. The final objective of the research is that using the interface system developed in this research, we reconstruct the image data transmitted to the personal computer in the form of the generalized data file

    Nuclear power plants are facing strong demands for higher reliability and cost-performance in their control and instrumentation systems. To meet these needs, Hitachi is developing advanced control and instrumentation technology by rationalizing the conventional technology in that field. The rationalization is done through the utilization of reliable digital technology and optical transmission technology, and others, which are now commonly used in computer applications. The goal of the development work is to ensure safe, stable operation of the plant facilities and to secure harmony between man and machine. To alleviate the burdens of the operators, the latest electronic devices are being employed to create an advanced man-machine interface, and to promote automatic operation of the plant based upon the automatic operation of individual systems. In addition, the control and instrumentation system, including the safety system, incorporates more and more digital components in order to further enhance the reliability and maintainability of the plant.

    Existing research suggests that digital games can be used effectively for educational purposes at any level of training. Perioperative nursing educators can use games to complement curricula, in guidance and staff development programs, to foster team collaboration, and to give support to critical thinking in nursing practice because it is a complex environment. To describe the process of developing an educational game to set up surgical instruments on the Mayo stand or back table as a resource to assist the instructor in surgical instrumentation training for students and nursing health professionals in continued education. The study was characterized by applied research in production technology. It included the phases of analysis and design, development, and evaluation. The objectives of the educational game were developed through Bloom's taxonomy. Parallel to the physical development of the educational game, a proposed model for the use of digital elements in educational game activities was applied to develop the game content. The development of the game called "Playing with Tweezers" was carried out in 3 phases and was evaluated by 15 participants, comprising students and professional experts in various areas of knowledge such as nursing, information technology, and education. An environment was created with an initial screen, menu buttons containing the rules of the game, and virtual tour modes for learning and assessment. The "digital" nursing student needs engagement, stimulation, reality, and entertainment, not just readings. "Playing with Tweezers" is an example of educational gaming as an innovative teaching strategy in nursing that encourages the strategy of involving the use of educational games to support theoretical or practical classroom teaching. Thus, the teacher does not work with only 1 type of teaching methodology, but with a combination of different methodologies. In addition, we cannot forget that skill training in an educational game does not

    Our recent work has concentrated on the development of high-resolution PET instrumentation reflecting in part the growing importance of PET in nuclear medicine imaging. We have developed a number of positron imaging instruments and have the distinction that every instrument has been placed in operation and has had an extensive history of application for basic research and clinical study. The present program is a logical continuation of these earlier successes. PCR-I, a single ring positron tomograph was the first demonstration of analog coding using BGO. It employed 4 mm detectors and is currently being used for a wide range of biological studies. These are of immense importance in guiding the direction for future instruments. In particular, PCR-II, a volume sensitive positron tomograph with 3 mm spatial resolution has benefited greatly from the studies using PCR-I. PCR-II is currently in the final stages of assembly and testing and will shortly be placed in operation for imaging phantoms, animals and ultimately humans. Perhaps the most important finding resulting from our previous study is that resolution and sensitivity must be carefully balanced to achieve a practical high resolution system. PCR-II has been designed to have the detection characteristics required to achieve 3 mm resolution in human brain under practical imaging situations. The development of algorithms by the group headed by Dr. Chesler is based on a long history of prior study including his joint work with Drs. Pelc and Reiderer and Stearns. This body of expertise will be applied to the processing of data from PCR-II when it becomes operational

    Being user friendly should be the main guidance, beside the self-understood high performance, in today's instrumentation development. Here we identify three components of the user-friendly policy: the all-in-one concept, customization, and connectivity. All-in-one is the concept of unification of various building blocks and thus various functionalities in one product. The customization is enabled by the product's reconfigurability that allows a product to grow and support new requirements and applications without changing hardware. The consequence of the two is the capacity of the single instrument to perform a variety of tasks that before were split among different devices. The last of the three is connectivity that improves the relationship between controls and beam diagnostics, brings out-of-the-crate freedom, and opens unforeseen possibilities for intra-accelerator cooperation and remote technical support

    Over its more than thirty-year history, the Advanced Technologies and Instrumentation (ATI) program within the Division of Astronomical Sciences has provided grants to support the development and deployment of detectors and instrumentation for ground-based astronomy. This program has enabled scientific advances in diverse fields from solar physics to exoplanets to cosmology. ATI has provided instrumentation for both small and large observatories from radio through visible wavebands. It has played a role in the early development of major initiatives such as the Large Synoptic Survey Telescope. Technology development for astronomy unfolds over a longer period than the lifetime of a single grant. This review will consider ATI from an historical perspective to assess its impact on astronomy.

    1982-06-01

    This paper describes developmental works on the instrumentation of the Experimental VHTR. In the area of the nuclear instrumentation for the reactor control, high temperature fission counter-chambers have been developed. These withstood the accelerated irradiation life tests at 600 deg. C, the long term in-reactor operating test at 600 deg. C and the 800 deg. C-operating tests for several hundred hours in a simulated accident condition. Platinum-Molybdenum alloy thermocouples have been studied as a neutron-irradiation-resistant high-temperature thermocouple for the in-core temperature distribution monitoring of the VHTR in the temperature range between 1000 deg. C and 1350 deg. C. The instability problems of the Pt-5% Mo/Pt-0.1% Mo thermocouple seem to be overcome by introducing a double sheath structure and adopting a better material to the inner sheath. A local failure and abnormality monitoring method for the HTR fuel is also studied using a gas-sweeping irradiation rig for the CPF compacts. This study aims mainly at the development of a method to compensate for the dependency of the FP-release rate on the fuel temperature, the neutron flux density, the burn-up and others, in order to increase the detection sensitivity of fuel failures.

    Full Text Available Objectives: The goal of this project was to develop the first disease-specific instrument for the evaluation of quality of life in chronic pancreatitis. Methods: Focus groups and interview sessions were conducted, with chronic pancreatitis patients, to identify items felt to impact quality of life which were subsequently formatted into a paper-and-pencil instrument. This instrument was used to conduct an online survey by an expert panel of pancreatologists to evaluate its content validity. Finally, the modified instrument was presented to patients during precognitive testing interviews to evaluate its clarity and appropriateness. Results: In total, 10 patients were enrolled in the focus groups and interview sessions where they identified 50 items. Once redundant items were removed, the 40 remaining items were made into a paper-and-pencil instrument referred to as the Pancreatitis Quality of Life Instrument. Through the processes of content validation and precognitive testing, the number of items in the instrument was reduced to 24. Conclusions: This marks the development of the first disease-specific instrument to evaluate quality of life in chronic pancreatitis. It includes unique features not found in generic instruments (economic factors, stigma, and spiritual factors. Although this marks a giant step forward, psychometric evaluation is still needed prior to its clinical use.

    The assessment of activities of daily living (ADL) is essential for dementia diagnostics. Even in mild cognitive impairment (MCI), subtle deficits in instrumental ADL (IADL) may occur and signal a higher risk of conversion to dementia. Thus, sensitive and reliable ADL assessment tools are important. Smart homes equipped with sensor technology and video cameras may provide a proxy-free assessment tool for the detection of IADL deficits. The aim of this paper is to investigate the potential of a smart home environment for the assessment of IADL in MCI. The smart home consisted of a two-room flat equipped with activity sensors and video cameras. Participants with either MCI or healthy controls (HC) had to solve a standardized set of six tasks, e.g., meal preparation, telephone use, and finding objects in the flat. MCI participants needed more time (1384 versus 938 seconds, p smart home technologies offer the chance for an objective and ecologically valid assessment of IADL. It can be analyzed not only whether a task is successfully completed but also how it is completed. Future studies should concentrate on the development of automated detection of IADL deficits.

    Radiation detector is the key component in precise and accurate measurement of the nuclear radiations. The detectors deployed for radiation measurements in broadly classified sectors of Energy, Security, Discovery Science and Health and Environments are in general specific to their applications. The nuclear reactors as well as the fuel processing including waste management in energy sector require wide range/variety of detectors and the instruments for safe and precise generation of power. The security sector has gained importance in radiation monitoring in the present security perspective and there are many challenges in development of detector technology. The Discovery Science or the mega science projects viz CERN, Fermilab, GANIL, INO, MACE telescope, ITER etc have continuously generated new demand on detector related technologies that have been also found to be useful in other applications. Similarly, the health and environment monitoring have been also evolving with new technologies and techniques to address the requirement's arising in projects of new nuclear programs

    A proper measurement of the relevant single and two-phase flow parameters is the basis for the understanding of many complex thermal-hydraulic processes. Reliable instrumentation is therefore necessary for the interaction between analysis and experiment especially in the field of nuclear safety research where postulated accident scenarios have to be simulated in experimental facilities and predicted by complex computer code systems. The so-called conventional instrumentation for the measurement of e. g. pressures, temperatures, pressure differences and single phase flow velocities is still a solid basis for the investigation and interpretation of many phenomena and especially for the understanding of the overall system behavior. Measurement data from such instrumentation still serves in many cases as a database for thermal-hydraulic system codes. However some special instrumentation such as online concentration measurement for boric acid in the water phase or for non-condensibles in steam atmosphere as well as flow visualization techniques were further developed and successfully applied during the recent years. Concerning the modeling needs for advanced thermal-hydraulic codes, significant advances have been accomplished in the last few years in the local instrumentation technology for two-phase flow by the application of new sensor techniques, optical or beam methods and electronic technology. This paper will give insight into the current state of instrumentation technology for safety-related thermohydraulic experiments. Advantages and limitations of some measurement processes and systems will be indicated as well as trends and possibilities for further development. Aspects of instrumentation in operating reactors will also be mentioned.

    Described herein are the FY 1999 results of development of the photon-aided instrumentation and processing technologies. The photon technologies will be widely applicable to various industrial areas, e.g., medical, diagnostic, communication, transmission and chemical areas, in addition to instrumentation and processing, and the FY 1999 project is directed to the survey and analysis of the information, and prediction of their effects. The high-sensitivity light-receiving elements enlarged up to 5mm diameter (effective area) are developed, based on the technologies to grow the thin films using an MOVPE (metal-organic vapor-phase epitaxy) device and the results of development of the infrared ray-receiving InGaAs photodiode sensitive in a 2.5 to 2.7{mu}m wavelength range. The surface roughness of 0.4nmRMS is achieved by the bowl feed liquid polishing method, to develop the processing technologies for high-precision substrates for optical mirrors. The results are used to develop the prototype X-ray mirrors with surface accuracy of {lambda}/10 to {lambda}/20 and roughness of 0.3 to 0.5nmRMS. In the development of the technologies for the light sources which can sufficiently supply photons for exciting semiconductor lasers, the technologies are developed to efficiently converge the laser beams. Also developed are the apparatus which can converge the beams to a diameter of around 0.6mm, and the apparatus which uses optical fibers to evaluate the beam diameter. (NEDO)

    For several years Los Alamos has incorporated microprocessors into instruments to expand the capability of portable survey type equipment. Beginning with portable pulse height analyzers, the developments have expanded to small dedicated instruments which handle the measurement and interpretation of various radiation fields. So far, instruments to measure gamma rays, neutrons, and beta particles have been produced. The computer capability built into these instruments provides significant computational power into the instruments. Capability unheard of a few years ago in small portable instruments is routine today. Large computer-based laboratory measurement systems which required much space and electrical power can now be incorporated in a portable hand-held instrument. The microprocessor developments at Los Alamos are now restricted to radiation monitoring equipment but can be expanded to chemical and biological applications as well. Applications for radiation monitoring equipment and others are discussed

    Industrial radioisotope instruments are emerging as advanced monitoring, controlling and automation tools for industries in China. Especially the on-line analysis systems based on radioisotope instruments, referred to as nucleonic control systems (NCS), have more and more important role in the modernization and optimization of industrial processes. Over nearly four decades significant progress has been made in the development and application of radioisotope instruments in China. After a brief review of the history of radioisotope instruments, the state of the art of this kind of instruments and recent examples of their applications are given. Technical and economic benefits have resulted from the industrial applications of radioisotope instruments and the sales of products of their own in marketing. It is expected that along with the high speed growth of national economy, there will be greater demand for radioisotope instruments and nucleonic control systems in Chinese industry to promote the technological transformation and progress of traditional industries and to establish high-tech industries with technology-intensive products. Sustained efforts for the research and development of radioisotope instrument should be made to up-grade domestic instruments and to satisfy the needs of the smaller scale industries more common in China for low cost systems.

    Terrestrial gamma-ray flashes (TGFs) are brief MeV gamma-ray flashes that are associated with thunderstorms, around 12km in altitude, and are viewed by orbiting satellites. These bright flashes of high energy photons were discovered in 1994. The two major models for TGFs that originate in thunderstorms are the Lightning Leader and Relativistic Feedback Discharge (RFD) model. Both depend on energetic electrons radiating via bremsstrahlung emission. The Lightning Leader model theorizes that lightning step leaders can accelerate electrons to relativistic speeds. The RFD model states that an energetic seed particle can be accelerated to relativistic speeds by strong electric fields inside of a thunderstorm. The main difference in the results of the two models is as follows; the Lightning Leader model results in a wider beam of gamma-rays than the RFD model because the electric field of a thunderstorm is more structured than that of lightning. The TRYAD mission will be the first to fly two detectors, inside CubeSats, in formation to detect TGFs from multiple points in the sky. The data from the CubeSats and the World Wide Lightning Location Network (WWLLN) will likely provide enough insight to constrain or eliminate some of the existing models for TGFs.This summer was spent testing components and constructing the engineering model of the scientific instrument that will be used to detect TGFs. The detector is made up of four lead-doped plastic scintillators which are coupled to arrays of Silicon Photomultipliers (SiPM). The signal from the SiPM array is then fed into a discriminator where a lower energy estimate can be determined and photon counts are recorded. I will present the progress made over the summer constructing the engineering model.

    To develop educational technology with caregivers of older people based on the needs, difficulties and concerns related to the elderly care expressed by the caregivers themselves. Research of qualitative nature, with participant observation, based on concepts used by Paulo Freire. Data collection and analysis used the "World Cafe" methodology and the thematic content analysis, respectively. The needs of these caregivers refer to their training and information on aging. The difficulties highlighted are deterrents to quality assistance to older adults, such as: insufficient resources, environmental factor and relationship with the family. The interests are evident in relation to the care and to its more subjective relationship. Final considerations: Educational technologies, printed matter and media, developed along with the caregivers, contribute to orientation and information of caregiver, population and professionals as facilitating instruments, regarding elderly care.

    This paper summarizes the requisites for small animal PET scanners, present state of their market and of their development in National Institute of Radiological Sciences (NIRS). Relative to the apparatus clinically used, the requisites involve the high spatial resolution of 0.8-1.5 mm and high sensitivity of the equipment itself due to low dose of the tracer to be given to animals. At present, more than 20 institutions like universities, research facilities and companies are developing the PET equipment for small animals and about 10 machines are in the market. However, their resolution and sensitivity are not fully satisfactory and for their improvement, investigators are paying attention to the gamma ray measurement by depth-of-interaction (DOI) method. NIRS has been also developing the machine jPET-D4 and has proposed to manufacture jPET-RD having 4-layer DOI detectors with the absolute central sensitivity as high as 14.7%. jPET-RD is to have the spatial resolution as high as <1mm (central view) and -1.4 mm (periphery).

    1990-01-01

    In his July 1989 space policy speech, President Bush proposed a long range continuing commitment to space exploration and development. Included in his goals were the establishment of permanent lunar and Mars habitats and the development of extended duration space transportation. In both cases, a major issue is the availability of qualified sensor technologies for use in real-time monitoring and control of integrated physical/chemical/biological (p/c/b) Environmental Control and Life Support Systems (ECLSS). The purpose of this study is to determine the most promising instrumentation technologies for future ECLSS applications. The study approach is as follows: 1. Precursor ECLSS Subsystem Technology Trade Study - A database of existing and advanced Atmosphere Revitalization (AR) and Water Recovery and Management (WRM) ECLSS subsystem technologies was created. A trade study was performed to recommend AR and WRM subsystem technologies for future lunar and Mars mission scenarios. The purpose of this trade study was to begin defining future ECLSS instrumentation requirements as a precursor to determining the instrumentation technologies that will be applicable to future ECLS systems. 2. Instrumentation Survey - An instrumentation database of Chemical, Microbial, Conductivity, Humidity, Flowrate, Pressure, and Temperature sensors was created. Each page of the sensor database report contains information for one type of sensor, including a description of the operating principles, specifications, and the reference(s) from which the information was obtained. This section includes a cursory look at the history of instrumentation on U.S. spacecraft. 3. Results and Recommendations - Instrumentation technologies were recommended for further research and optimization based on a consideration of both of the above sections. A sensor or monitor technology was recommended based on its applicability to future ECLS systems, as defined by the ECLSS Trade Study (1), and on whether its

    Brenac, A.

    1987-02-01

    Experimental developments principally concerning electron sources for inverse photoemission are presented. The specifications of the electron beam are derived from experiment requirements, taking into account the limitations encountered (space charge divergence). For a wave vector resolution of 0.2 A -1 , the maximum current is 25 microA at 20 eV. The design of a gun providing such a beam in the range 5 to 50 eV is presented. Angle-resolved inverse photoemission experiments show angular effects at 30 eV. For an energy of 10 eV, angular effects should be stronger, but the low efficiency of the spectrometer in this range makes the experiments difficult. The total energy resolution of 0.3 eV is the result mainly of electron energy spread, as expected. The electron sources are based on field effect electron emission from a cathode consisting of a large number of microtips. The emission arises from a few atomic cells for each tip. The ultimate theoretical energy spread is 0.1 eV. This value is not attained because of an interface resistance problem. A partial solution of this problem allows measurement of an energy spread of 0.9 eV for a current of 100 microA emitted at 60 eV. These cathodes have a further advantage in that emission can occur at a low temperature [fr

    Full Text Available The Common Instrument Middleware Architecture (CIMA model for Web services based monitoring of remote scientific instruments is being extended and enhanced to provide a capability for remote instrument control. X-ray diffraction has been selected as an ideal domain for prototype development, with the goal being a comprehensive and feature rich portal system for access to remote instruments and their data. The system has two principle components, one of which serves the instrument and data, and the second serves the client user. Plugin modules are used to provide flexibility and re-use, and the notion of plugin control is being developed. The architecture supports remote access to multiple instruments from a single portal. The use of Web 2.0 Pushlet and AJAX technologies has been introduced for push based portlet refresh and updating. An X3D based 3D virtual representation of the instrument provides data collection simulation and (pseudo real time instrument representation.

    Variety of nuclear instruments are required for different applications in reactors such as reactor start-up, reactor protection and regulating system, area monitoring, failed fuel detection, stack monitoring etc. Attempts are made to develop a standardized microcomputer based hardware for configuring different types of instruments. PC architecture is chosen due to easy availability of components/boards and software. These instruments have dual redundant Network Interface Cards for connecting to a Primary Radiation Data LAN which in turn can be connected to Plant Information Bus through Gateways. These SMART instruments can be tested/calibrated through specific commands from remote computers connected over the LAN. This paper describes the various issues involved and the design details.

    Background:Few studies have examined students' attitudinal perceptions of technology. There is no appropriate instrument to measure senior high school students' motivation and self-regulation toward technology learning among the current existing instruments in the field of technology education. Purpose:The present study is to validate an instrument for assessing senior high school students' motivation and self-regulation towards technology learning. Sample:A total of 1822 Taiwanese senior high school students (1020 males and 802 females) responded to the newly developed instrument. Design and method:The Motivation and Self-regulation towards Technology Learning (MSRTL) instrument was developed based on the previous instruments measuring students' motivation and self-regulation towards science learning. Exploratory and confirmatory factor analyses were utilized to investigate the structure of the items. Cronbach's alpha was applied for measuring the internal consistency of each scale. Furthermore, multivariate analysis of variance was used to examine gender differences. Results:Seven scales, including 'Technology learning self-efficacy,' 'Technology learning value,' 'Technology active learning strategies,' 'Technology learning environment stimulation,' 'Technology learning goal-orientation,' 'Technology learning self-regulation-triggering,' and 'Technology learning self-regulation-implementing' were confirmed for the MSRTL instrument. Moreover, the results also showed that male and female students did not present the same degree of preference in all of the scales. Conclusions:The MSRTL instrument composed of seven scales corresponding to 39 items was shown to be valid based on validity and reliability analyses. While male students tended to express more positive and active performance in the motivation scales, no gender differences were found in the self-regulation scales.

    A new instrumentation architecture for radiation spectroscopy is in the early stages of development at Savannah River. Based upon the same digital sampling techniques used in sonar and radar, sampled data spectroscopy (SDS) has produced Na(I)/PMT spectra with resolution comparable to conventional PHA systems. This work has laid the foundation for extending SDS techniques to solid state detector applications as well. Two-dimensional SDS processes raw, unintegrated detector output pulses to produce both energy and shape information that is used to construct a conventional energy spectrum. System advantages include zero electronic deadtime to support very high count rates, elimination of pulse pile-up peaks, high noise immunity, and digital system stability and reliability. Small size and low power requirements make 2-D SDS anideal technology for portable instrumentation and remote monitoring applications. Applications of potential interest at Savannah River include on-the-spot spill analysis, real-time waste stream monitoring, and personnel and area monitoring below background levels. A three-dimensional sampled data architecture is also being developed. Relying on image analysis and enhancement techniques, 3-D SDS identifies spectral peaks without determining the energy of any individual detector pulses. These techniques also open up a new avenue of exploration for reducing or removing Compton effects from the spectra of single detector systems. The intended application for this technique is waste characterization where lower energy isotopes are often obscured by the Compton scattering from dominant isotopes such as Csl37

    The FLuorescence Imaging Spectrometer (FLORIS) is the payload of the FLuorescence Explorer Mission (FLEX) of the European Space Agency. The mission objective is to perform quantitative measurements of the solar induced vegetation fluorescence to monitor photosynthetic activity. FLORIS works in a push-broom configuration and it is designed to acquire data in the 500-780 nm spectral range, with a sampling of 0.1 nm in the oxygen bands (759-769 nm and 686- 697 nm) and 0.5-2.0 nm in the red edge, chlorophyll absorption and Photochemical Reflectance Index bands. FLEX will fly in formation with Sentinel-3 to benefit of the measurements made by the Sentinel-3 instruments OLCI and SLSTR, particularly for cloud screening, proper characterization of the atmospheric state and determination of the surface temperature. The instrument concept is based on a common telescope and two modified Offner spectrometers with reflective concave gratings both for the High Resolution (HR) and Low Resolution (LR) spectrometers. In the frame of the instrument pre-development Leonardo Company (I) has built and tested an elegant breadboard of the instrument consisting of the telescope and the HR spectrometer. The development of the LR spectrometer is in charge of OHB System AG (D) and is currently in the manufacturing phase. The main objectives of the activity are: anticipate the development of the instrument and provide early risk retirement of critical components, evaluate the system performances such as imaging quality parameters, straylight, ghost, polarization sensitivity and environmental influences, verify the adequacy of critical tests such as spectral characterization and straylight, define and optimize instrument alignment procedures. Following a brief overview of the FLEX mission, the paper will cover the design and the development of the optics breadboard with emphasis on the results obtained during the tests and the lessons learned for the flight unit.

  9. Using XML and Java Technologies for Astronomical Instrument Control

    2001-01-01

    Traditionally, instrument command and control systems have been highly specialized, consisting mostly of custom code that is difficult to develop, maintain, and extend. Such solutions are initially very costly and are inflexible to subsequent engineering change requests, increasing software maintenance costs. Instrument description is too tightly coupled with details of implementation. NASA Goddard Space Flight Center, under the Instrument Remote Control (IRC) project, is developing a general and highly extensible framework that applies to any kind of instrument that can be controlled by a computer. The software architecture combines the platform independent processing capabilities of Java with the power of the Extensible Markup Language (XML), a human readable and machine understandable way to describe structured data. A key aspect of the object-oriented architecture is that the software is driven by an instrument description, written using the Instrument Markup Language (IML), a dialect of XML. IML is used to describe the command sets and command formats of the instrument, communication mechanisms, format of the data coming from the instrument, and characteristics of the graphical user interface to control and monitor the instrument. The IRC framework allows the users to define a data analysis pipeline which converts data coming out of the instrument. The data can be used in visualizations in order for the user to assess the data in real-time, if necessary. The data analysis pipeline algorithms can be supplied by the user in a variety of forms or programming languages. Although the current integration effort is targeted for the High-resolution Airborne Wideband Camera (HAWC) and the Submillimeter and Far Infrared Experiment (SAFIRE), first-light instruments of the Stratospheric Observatory for Infrared Astronomy (SOFIA), the framework is designed to be generic and extensible so that it can be applied to any instrument. Plans are underway to test the framework

    1984-01-01

    The ultrasonic flaw detectors with 'A-scope indication' have been frequently used as the means for confirming the soundness of structures and equipments, but there are problems in their operational, quantifying and recording capabilities. Recently, the digital ultrasonic measuring instrument of touch panel type ''UT 1000 Series'' has been developed, which resolves these problems by a single effort. This measuring instrument is that of portable type, which gives the digital output of measured results in real time only by lightly touching the peak point of an echo on the Brown tube. This instrument contains the rich software for measurement, and can measure the positions and dimensions of defects and the pressure on contact surfaces with high accuracy. 'A-scope indication' is the indication with an oscilloscope taking the intensity of echo and the propagation time of ultrasonic waves on the ordinate and abscissa, respectively. There are three types of the instrument, that is, for detecting defects, for measuring contact surface pressure and for both purposes. The size of the instrument is 240 mm width, 350 mm length and 175 mm height, and the weight is 8.5 kgf. The specification, function and features of the ultrasonic flaw detector, touch panel, gain setter, key board, microcomputer and others are reported. (Kako, I.)

    Full Text Available The rapid increase and availability of mathematics software, either for classroom or individual learning activities, presents a challenge for teachers. It has been argued that many products are limited in quality. Some of the more commonly used software products have been criticized for poor content, activities which fail to address some learning issues, poor graphics presentation, inadequate documentation, and other technical problems. The challenge for schools is to ensure that the educational software used in classrooms is appropriate and effective in supporting intended outcomes and goals. This paper aimed to develop instrument for evaluating mathematics educational software in order to help teachers in selecting the appropriate software. The instrument considers the notion of educational including content, teaching and learning skill, interaction, and feedback and error correction; and technical aspects of educational software including design, clarity, assessment and documentation, cost and hardware and software interdependence. The instrument use a checklist approach, the easier and effective methods in assessing the quality of educational software, thus the user needs to put tick in each criteria. The criteria in this instrument are adapted and extended from standard evaluation instrument in several references.   Keywords: mathematics educational software, educational aspect, technical aspect.

    Highlights: • We developed a strategy for the development of instrumentation for EU ITER TBSs. • TBSs instrumentation functions: safety, operation and scientific mission. • Described activities are in support of ITER design review process. -- Abstract: The instrumentation of the HCLL and HCPB Test Blanket System is fundamental in ensuring that ITER safety and operational requirements are satisfied as well as in enabling the scientific mission of the TBM program. It carries out three essential functions: (i) safety, intended as compliance with ITER requirements toward public and workers protection; (ii) system control, intended as compliance with ITER operational requirements and investment protection; and (iii) scientific mission, intended as validating technology and predictive tools for blanket concepts relevant to fusion energy systems. This paper describes the strategy for instrumentation development by providing details of the following five steps to be implemented in procured activities in the short to mid-term (3–4 years): (i) provide mapping of sensors requirements based on critical review of preliminary design data; (ii) develop functional specifications for TBS sensors based on the analysis of operative conditions in the various ITER buildings in which they are located; (iii) assess availability of commercial sensors against developed specifications; (iv) develop prototypes when no available solution is identified; and (v) perform single effect tests for the most critical solicitations and post-test examination of commercial products and prototypes. Examples of technology assessment in two technical areas are included to reinforce and complement the strategy description.

    Contaminated soils pose a significant challenge for characterization and remediation programs that require rapid, accurate and comprehensive data in the field or laboratory. Environmental analyzers based on supercritical fluid (SF) technology have been designed and developed for meeting these global needs. The analyzers are designated the CHAMP Systems (Chemical Hazards Automated Multimedia Processors). The prototype instrumentation features SF extraction (SFE) and on-line capillary gas chromatographic (GC) analysis with chromatographic and/or spectral identification detectors, such as ultra-violet, Fourier transform infrared and mass spectrometers. Illustrations are given for a highly automated SFE-capillary GC/flame ionization (FID) configuration to provide validated screening analysis for total extractable hydrocarbons within ca. 5--10 min, as well as a full qualitative/quantitative analysis in 25--30 min. Data analysis using optional expert system and neural networks software is demonstrated for test gasoline and diesel oil mixtures in this integrated intelligent instrument approach to trace organic analysis of soils and sediments

    2013-10-01

    Purpose: The purpose of this study was to develop an instrument to measure psychological ownership in a South African context. Motivation for the study: It was found that previous instruments for the measurement of psychological ownership lacked the ability to grasp the extensive reach of psychological ownership. Research design, approach and method: A quantitative cross-sectional survey was conducted on a non-probability convenience sample of 713 skilled, highly-skilled and professional employees from various organisations in both the private and public sectors in South Africa. Main findings: Although a 69-item measurement instrument was developed in order to capture the proposed seven-dimensional psychological ownership construct, it became evident when analysing the data that a four-factor model comprising 35 items was suitable. Practical/managerial implications: If a sense of psychological ownership toward an organisation could be established amongst its employees by addressing the factors as measured by the South African Psychological Ownership Questionnaire, organisations could become enhanced workplaces and, as a result, sustainable performance could be promoted and staff could be retained. Contribution/value-add: The instrument for measuring psychological ownership in a South African context could serve as a diagnostic tool that would allow human resource professionals and managers to determine employees’ sense of psychological ownership regarding their organisation and to focus specifically on weak dimensional areas that could be improved.

  18. Policy instruments for development of wind power in Sweden

    2003-01-01

    It is often believed that energy policy and policy instruments can play a significant role in the transition towards sustainable energy by stimulating and accelerating the development and deployment of new energy technologies. However, despite the known need for, and benefits of, new energy technologies their market introduction and expansion is often slow. Wind power has been on the political agenda since the 1970s in several European countries as well as in other countries throughout the world. However, the technology and market development of wind power has been very different in these countries. Despite three decades of policy intervention the installed capacity in Sweden was only 265 MW in 2000, compared with 6,107 MW in Germany, 2,836 MW in Spain and 2,341 MW in Denmark. This report analyses the effects of policy instruments on wind power development in Sweden and identifies possible reasons why wind power has not been installed to a greater extent. The analysis is based on an empirical example of a socio technological system-based approach to evaluation of technology and market development for new energy technologies; i.e. an approach focused on the technological system including the actors, institutions and organizations that build, drive and utilise it and the economic and legal framework that regulates it. The aim is to assess the impact on technology and market development and to discuss the relatively late and slow wind power development in Sweden. The report also examines the achievement of governmental energy policy goals. Using the socio-technological systems approach we analyse Swedish policy programmes and wind power development between 1975 and 2000. The political and economic framework is identified. The discussion of the political and economic frameworks is limited to public policy goals and policy instruments. The policy focus is set to policy instruments aimed for technology and market development of wind power, such as research and

    Described herein are the FY 2000 results of development of the photon-aided instrumentation and processing technologies, aimed at improving efficiency of the production processes which have been massively consuming energy, e.g., those for welding, joining, surface treatment and granulation for producing fine particles. The program for production of the functional composite compounds by the microscopic processing technologies prepares the electrically resistant films and dielectric films by in-situ mixing two types of the ultrafine particles. The program for the in-situ measuring technology is aimed at measuring contents of the constituent components of fine particles, 30nm or less in size, to an accuracy of 10% by the emission spectroscopy, after making them plasmatic. The program for the high-power, all-solid-state laser technology is developing the excited chamber for the high-power, all-solid-state slab type laser, in order to realize the energy-efficient laser-aided processing. The program for the tightly-focusing, all-solid-state laser technology develops the highly uniform crystals by growing the GLBO crystals for producing the high-power ultraviolet laser beams, is developing the techniques for production of the wavelength converting elements, including the GLBO crystal package, and develops the wavelength conversion method by the fourth-harmonic generation with the all-solid-state laser beams as the fundamental wave, realizing the high harmonic power of 23W, for generating the high-power ultraviolet laser beams at a high efficiency.

    The project had three major aims: improvement of technology for high-speed cell and chromosome sorting; the use of such instrumentation in genome analysis; applying the principles developed and the lessons learned to automated processes for the genome program. The work was a continuation of studies that were started at the Lawrence Livermore National Laboratory before the PI moved to the University of Washington. At Livermore, a high-speed sorter for the selection of human chromosomes was built. The instrument incorporated Livermore`s advanced sorter technology. The engineering focused on improving robustness and reliability so that the full potential of high-speed sorting would become available to the biological research laboratory. The new instrument, dubbed MoFlo for modular flow cytometer, proved to be a very practical and efficient tool during the chromosome isolation phase of the gene-library project. Its reliability and ease of operation exceeded that of the commercial instruments. The technology was licensed to two companies.

    A versatile laser light scattering (LLS) instrument is developed for use in microgravity to measure microscopic particles of 30 A to above 3 microns. Since it is an optical technique, LLS does not affect the sample being studied. A LLS instrument built from modules allows several configurations, each optimized for a particular experiment. The multiangle LLS instrument can be mounted in the rack in the Space Shuttle and on Space Station Freedom. It is possible that a Space Shuttle glove-box and a lap-top computer containing a correlator card can be used to perform a number of experiments and to demonstrate the technology needed for more elaborate investigations. This offers simple means of flying a great number of experiments without the additional requirements of full-scale flight hardware experiments.

    2016-03-01

    The Atmospheric Sounder Spectrometer for Infrared Spectral Technology (ASSIST) measures the absolute infrared (IR) spectral radiance (watts per square meter per steradian per wavenumber) of the sky directly above the instrument. More information about the instrument can be found through the manufacturer’s website. The spectral measurement range of the instrument is 3300 to 520 wavenumbers (cm-1) or 3-19.2 microns for the normal-range instruments and 3300 to 400 cm-1 or 3-25 microns, for the extended-range polar instruments. Spectral resolution is 1.0 cm-1. Instrument field-of-view is 1.3 degrees. Calibrated sky radiance spectra are produced on cycle of about 141 seconds with a group of 6 radiance spectra zenith having dwell times of about 14 seconds each interspersed with 55 seconds of calibration and mirror motion. The ASSIST data is comparable to the Atmospheric Emitted Radiance Interferometer (AERI) data and can be used for 1) evaluating line-by-line radiative transport codes, 2) detecting/quantifying cloud effects on ground-based measurements of infrared spectral radiance (and hence is valuable for cloud property retrievals), and 3) calculating vertical atmospheric profiles of temperature and water vapor and the detection of trace gases.

    Energy and technology are essential ingredients of development, it is only through their use that it became possible to sustain a population of almost 5 billion on Earth. The challenges to eradicate poverty and underdevelopment in developing countries in the face of strong population increases can only be successfully met with the use of advanced technology, leapfrogging the path followed in the past by today's industrialized countries. It is shown in the paper that energy consumption can be decoupled from economic development. Such possibility will contribute significantly in achieving sustainable development. 10 refs., 4 figs., 3 tabs.

    1992-07-01

    Economic development in developing countries must be accomplished in a manner that does not harm the environment with pollution. Pollution harms human health and productivity. Thus appropriate strategies must be developed that promote growth, reduce poverty, and protect the environment. A review of the current literature is performed with attention paid to cost-effective interventions i.e., comparisons of regulatory and fiscal instruments that can reduce pollution. Both direct instruments (like effluent charges, tradable permits, deposit refund systems, emission regulations and regulatory agency funding for purification, cleanup, waste disposal, and enforcement) and indirect instruments (like input/output taxes and subsidies, substitution subsidies, abatement inputs, regulation of equipment and processes, and development of clean technologies) are examined. Examples are used to show how indirect instruments can be successful when monitoring and enforcement is too costly. A careful examination of distributive concerns illustrate how the effect on the poor may need particular consideration and how groups with vested interests can help evaluate the probable success of such interventions.

    Peer review panels composed of 80 external scientists recently visited Oak Ridge National Laboratory (ORNL) to review almost 700 proposals for experiments on 23 instruments at the Spallation Neutron Source (SNS) and High Flux Isotope Reactor (HFIR). These were proposed for the time period from January-June 2012. About 40% of the proposals were approved for beam time and 20% were placed on an alternate list if time becomes available. The Hybrid Spectrometer HYSPEC at SNS began its commissioning in September 2011. HYSPEC is otpimized for studying low energy dynamics in single-crystal samples using a broad variety of sample environments, and is equipped with a polarization analysis capability. It is expected to be available for users on a limited basis in the second half of 2012. The detector tank of CORELLI has been installed on beamline 9 at SNS. Now that the tank is in place, banks of neutron detectors and boron carbide shielding will be installed around the interior. CORELLI is optimized to probe complex disorder in crystalline materials through diffuse scattering from single-crystal samples. It will begin commissioning in 2014. CORELLI is one of four instruments being developed under the SING II (SNS Instruments Next Generation II) project. The others are the Macromolecular Neutron Diffractometer (MANDI), the Vibrational Spectrometer (VISION, scheduled to begin commissioning in 2012), and the Time of Flight Ultra Small Angle Neutron Scattering Instrument (TOF-USANS). The single crystal neutron diffractometer IMAGINE, was deliverd to HFIR in October 2011. Preliminary testing has been carried out. IMAGINE will provide atomic resolution information on chemical, organic, metallo-organic and protein single crystals that will enable their chemical, physical and biological structure and function to be understood.

    Virtual instruments (VIs) require metrological verification when applied as measuring instruments. Owing to the software-centered architecture, metrological evaluation of VIs includes two aspects: measurement functions and software characteristics. Complexity of software imposes difficulties on metrological testing of VIs. Key approaches and technologies for metrology evaluation of virtual instruments are investigated and analyzed in this paper. The principal issue is evaluation of measurement uncertainty. The nature and regularity of measurement uncertainty caused by software and algorithms can be evaluated by modeling, simulation, analysis, testing and statistics with support of powerful computing capability of PC. Another concern is evaluation of software features like correctness, reliability, stability, security and real-time of VIs. Technologies from software engineering, software testing and computer security domain can be used for these purposes. For example, a variety of black-box testing, white-box testing and modeling approaches can be used to evaluate the reliability of modules, components, applications and the whole VI software. The security of a VI can be assessed by methods like vulnerability scanning and penetration analysis. In order to facilitate metrology institutions to perform metrological verification of VIs efficiently, an automatic metrological tool for the above validation is essential. Based on technologies of numerical simulation, software testing and system benchmarking, a framework for the automatic tool is proposed in this paper. Investigation on implementation of existing automatic tools that perform calculation of measurement uncertainty, software testing and security assessment demonstrates the feasibility of the automatic framework advanced.

    The simplified boiling water reactor (SBWR) is based on utilizing to the maximum extent possible proven light water reactor (LWR) technology developed through 30 years of operating plant experience plus the advanced boiling water reactor (ABWR) technology development program. For the unique features, developmental programs have been put in place to qualify the design. Thus, the focus of technology development has been on the passive safety features - the gravity-driven ECCS (GDCS) and the containment heat removal (PCCS). General Electric constructed a full-height, scaled, integral facility to demonstrate the GDCS concept and provide data for methods qualification. For the PCCS, a three-pronged program was implemented. Basic heat transfer data were obtained via testing at the Massachusetts Institute of Technology and the University of California at Berkeley. A full-height scaled integral facility to demonstrate the PCCS concept and provide data for methods qualification was constructed in Japan in 1989. Initial testing is now complete. Design of a full-scale heat exchanger unit is underway and testing is planned for completion in early 1993

    The Robotics Technology Development Program (RTDP) is a ''needs-driven'' effort. A lengthy series of presentations and discussions at DOE sites considered critical to DOE's Environmental Restoration and Waste Management (EM) Programs resulted in a clear understanding of needed robotics applications toward resolving definitive problems at the sites. A detailed analysis of the Tank Waste Retrieval (TWR), Contaminant Analysis Automation (CAA), Mixed Waste Operations (MWO), and Decontamination ampersand Dismantlement (D ampersand D). The RTDP Group realized that much of the technology development was common (Cross Cutting-CC) to each of these robotics application areas, for example, computer control and sensor interface protocols. Further, the OTD approach to the Research, Development, Demonstration, Testing, and Evaluation (RDDT ampersand E) process urged an additional organizational break-out between short-term (1--3 years) and long-term (3--5 years) efforts (Advanced Technology-AT). The RDTP is thus organized around these application areas -- TWR, CAA, MWO, D ampersand D and CC ampersand AT -- with the first four developing short-term applied robotics. An RTDP Five-Year Plan was developed for organizing the Program to meet the needs in these application areas

    2007-06-15

    The spent fuel coming from the PWR is one of the most difficult problems to be solved for the continuous use of nuclear power. It takes a few million years to be safe under the ground. Therefore, it is not easy to take care of the spent fuel for such a long time. Transmutation technology is the key technology which can solve the spent fuel problem basically. Transmutation is to transmute long-lived radioactive nuclides in the spent fuel into short-lived or stable nuclide through nuclear reactions. The long-lived radioactive nuclides can be TRU and fission products such as Tc-99 and I-129. Although the transmutation technology does not make the underground disposal totally unnecessary, the period to take care of the spent fuel can be reduced to the order of a few hundred years. In addition to the environmental benefit, transmutation can be considered to recycle the energy in the spent fuel since the transmutation is performed through nuclear fission reaction of the TRU in the spent fuel. Therefore, transmutation technology is worth being developed in economical aspect. The results of this work can be a basis for the next stage research. The objective of the third stage research was to complete the core conceptual design and verification of the key technologies. The final results will contribute to the establishment of Korean back end fuel cycle policy by providing technical guidelines.

    2014-12-24

    Electron Cyclotron Heating (ECH) is needed for plasma heating, current drive, plasma stability control, and other applications in fusion energy sciences research. The program of fusion energy sciences supported by U. S. DOE, Office of Science, Fusion Energy Sciences relies on the development of ECH technology to meet the needs of several plasma devices working at the frontier of fusion energy sciences research. The largest operating ECH system in the world is at DIII-D, consisting of six 1 MW, 110 GHz gyrotrons capable of ten second pulsed operation, plus two newer gyrotrons. The ECH Technology Development research program investigated the options for upgrading the DIII-D 110 GHz ECH system. Options included extending present-day 1 MW technology to 1.3 – 1.5 MW power levels or developing an entirely new approach to achieve up to 2 MW of power per gyrotron. The research consisted of theoretical research and designs conducted by Communication and Power Industries of Palo Alto, CA working with MIT. Results of the study would be validated in a later phase by research on short pulse length gyrotrons at MIT and long pulse / cw gyrotrons in industry. This research follows a highly successful program of development that has led to the highly reliable, six megawatt ECH system at the DIII-D tokamak. Eventually, gyrotrons at the 1.5 megawatt to multi-megawatt power level will be needed for heating and current drive in large scale plasmas including ITER and DEMO.

    Remote portable seismic stations are, in most cases, constrained by logistics and cost. High latitude operations introduce environmental, technical and logistical challenges that require substantially more engineering work to ensure robust, high quality data return. Since 2006, IRIS PASSCAL has been funded by NSF to develop, deploy, and maintain a pool of polar specific seismic stations. At roughly the same time, PASSCAL began supporting experiments specifically targeting glacier dynamics such as the mechanisms of subglacial hydrology, basal shear stress, ice stream stick slip mechanisms, and glacier seismicity. Although much of the development for high-latitude deployments was directly applicable to cryoseismology, these new experiments introduced a unique series of challenges including high ablation, standing water, and moving stations. Our polar development objectives have focused on: Reducing station power requirements, size and weight; Extending the operational temperature of a station; Simplifying logistics; Engineering solutions that are cost effective, manufacturable, serviceable and reusable; And, developing high-latitude communications for both state-of-health and data transmission. To these ends, PASSCAL continues testing new power storage technology, refining established power systems for lighter and smaller power banks, and exploring telemetry solutions to increase high-bandwidth communication options and abilities for remote seismic stations. Further enhancing PASSCAL's ability to support cryoseismology is a recent NSF funded collaborative effort lead by Central Washing University joined by IRIS and New Mexico Tech to build a Geophysical Earth Observatory for Ice Covered Environments (GEOICE). The GEOICE instrument, power system and other integrated ancillary components are designed to require minimal installation time and logistical load (i.e., size and weight), while maximizing ease-of-use in the field and optimizing costs of instrumentation and

Production of the fine, functional circuits is studied for microscopic processing technology. The light source with variable wavelength-in a range of 2 to 5{mu}m for the solid-state laser, to measure concentration and composition of gases by the infrared absorption laser. The photon wave front compensator is being developed, to prevent disturbance-induced sensitivity deterioration for measurement of high temperature by the laser-aided ultrasonic instrumentation. The prototype of superconducting X-ray detector is developed, for high-sensitivity detection of impurities by measuring fluorescent X-ray. Development of the 10kW-class solid-state, rod-type laser is started for high-speed, high-precision laser-aided welding and cutting, and output of 11.3kW and electrical/optical conversion efficiency of 21.5% are achieved. An electrical/optical conversion efficiency of 17% is also achieved with the slab-type laser. An all-solid-state laser is being developed. It will produce high-energy pulses and high-quality beams capable of generating the beams which are converged very finely on the work with an average output power of 1KW (fundamental wave) and electrical/optical conversion efficiency of at least 20%.

    A new velocimetry system is currently being developed at NASA LaRC. The device, known as a Doppler global velocimeter (DGV), can record three velocity components within a plane simultaneously and in near real time. To make measurements the DGV, like many other velocimetry systems, relies on the scattering of light from numerous small particles in a flow field. The particles or seeds are illuminated by a sheet of laser light and viewed by two CCD cameras. The scattered light from the particles will have a frequency which is a function of the source laser light frequency, the viewing angle, and most importantly the seed velocities. By determining the scattered light intensity the velocity can be measured at all points within the light sheet simultaneously. Upon completion of DGV component construction and initial check out a series of tests in the Basic Aerodynamic Research (wind) Tunnel (BART) are scheduled to verify instrument operation and accuracy. If the results are satisfactory, application of the DGV to flight measurements on the F-18 High Alpha Research Vehicle (HARV) are planned. The DGV verification test in the BART facility will utilize a 75 degree swept delta wing model. A major task undertaken this summer included evaluation of previous results for this model. A specific series of tests matching exactly the previous tests and exploring new DGV capabilities were developed and suggested. Another task undertaken was to study DGV system installation possibilities in the F-18 HARV aircraft. In addition, a simple seeding system modification was developed and utilized to make Particle Imaging Velocimetry (PIV) measurements in the BART facility.

    Part of the French Alternative Energies and Atomic Energy Commission (CEA), the National Institute for Nuclear Science and Technology (INSTN) is a higher education institution whose mission is to provide students and professionals a high level of scientific and technological qualification in all disciplines related to nuclear energy applications. In this frame, INSTN carries out education and training (E and T) programs in nuclear instrumentation and radioprotection. Its strategy has always been to complete theoretical courses by training courses and laboratory works carried out on an extensive range of training tools that includes a large panel of nuclear instrumentation as well as software applications. Since its creation in 1956, the INSTN has conducted both education and vocational programs on ionizing radiation detection. An extensive range of techniques have commonly been used during practical works with students and employees of companies who need to get the knowledge and specialization in this field. Today, the INSTN is mainly equipped with usual detectors and electronics in large numbers in order to be able to accommodate up to 48 trainees at the same time in two classrooms, with only two trainees for one workstation in order to optimize their learning. In the field of the neutron detection systems, the INSTN has strongly developed its offer taking advantage of the use of research reactors, such as ISIS reactor (700 kW) at Saclay. The implementation of neutron detection systems specific to the courses offers a unique way of observing and analysing the signal coming from neutron detectors, as well as learning how to set the parameters of the detection system in real conditions.

    Nowadays, mobile technologies are part of everyday life, but the lack of instruments to assess their acceptability for the management of chronic diseases makes their actual adoption for this purpose slow. The objective of this study was to develop a survey instrument for assessing patients' attitude toward and intention to use mobile technology for diabetes mellitus (DM) self-management, as well as to identify sociodemographic characteristics and quality of life factors that affect them. We first conducted the documentation and instrument design phases, which were subsequently followed by the pilot study and instrument validation. Afterward, the instrument was administered 103 patients (median age: 37 years; range: 18-65 years) diagnosed with type 1 or type 2 DM, who accepted to participate in the study. The reliability and construct validity were assessed by computing Cronbach's alpha and using factor analysis, respectively. The instrument included statements about the actual use of electronic devices for DM management, interaction between patient and physician, attitude toward using mobile technology, and quality of life evaluation. Cronbach's alpha was 0.9 for attitude toward using mobile technology and 0.97 for attitude toward using mobile device applications for DM self-management. Younger patients (Spearman's ρ =-0.429; P higher education level (Kendall's τ =0.51; P mobile assistive applications for DM control. Moreover, patients with a higher quality of life presented a significantly more positive attitude toward using modern technology (Spearman's ρ =0.466; P mobile technology for DM self-management. Additionally, we found that even if most of the patients showed positive attitude toward mobile applications, only a moderate level of intention to indeed use them was observed. Moreover, the study indicated that barriers were truthfulness and easiness to use.

    Neutron scattering instruments in HANARO research reactor have been contributed to various fields of basic science and material engineering. These instruments are open to publics and researchers can apply beam-time and do experiments with instrument scientists. In most cases, these instruments run for several weeks without stopping, and therefore instrument scientist wants to see the instrument status and receive information if the instruments have some problem. This is important for the safety. However, it is very hard to get instrument information outside of instruments. Access from external site is strongly forbidden in the institute due to the network safety, I developed another way to send instrument status information using commercial short messaging service(SMS). In this presentation, detailed features of this system will be shown. As a prototype, this system is being developed for the single instrument: Disk-chopper time-of-flight instruments (DC-TOF). I have successfully developed instruments and operate for several years. This information messaging system can be used for other neutron scattering instruments.

    The human brain functions through a chemically-induced biological process which operates in a manner similar to electrical systems. The signal resulting from this biochemical process can actually be monitored and read using tools and having patterns similar to those found in electrical and electronics engineering. The primary signature of this electrical activity is the ''brain wave'', which looks remarkably similar to the output of many electrical systems. Likewise, the device currently used in medical arenas to read brain electrical activity is the electroencephalogram (EEG) which is synonymous with a multi-channel oscilloscope reading. Brain wave readings and recordings for medical purposes are traditionally taken in clinical settings such as hospitals, laboratories or diagnostic clinics. The signal is captured via externally applied scalp electrodes using semi-viscous gel to reduce impedance. The signal will be in the 10 to 100 microvolt range. In other instances, where surgeons are attempting to isolate particular types of minute brain signals, the electrodes may actually be temporarily implanted in the brain during a preliminary procedure. The current configurations of equipment required for EEGs involve large recording instruments, many electrodes, wires, and large amounts of hard disk space devoted to storing large files of brain wave data which are then eventually analyzed for patterns of concern. Advances in sensors, signal processing, data storage and microelectronics over the last decade would seem to have paved the way for the realization of devices capable of ''real time'' external monitoring, and possible assessment, of brain activity. A myriad of applications for such a capability are likewise presenting themselves, including the ability to assess brain functioning, level of functioning and malfunctioning. Our plan is to develop the sensors, signal processing, and portable instrumentation package which could

    Full Text Available The article considers the process and develops the conception of management of the proactive development of enterprises. The main instruments of management of enterprises’ development have been allocated on the system, process, and micro-process levels. The economic-mathematical model of formation of the optimal program of enterprise’s development has been built with reflection of interests of the most significant stakeholders and the basic types of projects which are combined in the program of development of enterprise. Taking account of the peculiarities of activity together with the objectives of industrial enterprises’ development, the following groups of projects are selected: technical and technological, providing for the change of the level of technology at the enterprise; productive, aimed at quantitative and qualitative change of production of enterprise, increase of its competitiveness; organizational, leading to changes in the organization, structure, and management of enterprise. The choice of the most acceptable private optimal program of enterprise’s development is carried out using the matrix method. According to this method, the absolute values of indicators of the socio-economic development of enterprises become relative with the subsequent transition to the definition of integral estimates for each program. It is also possible to use the methods of compromise programming that allow to obtain a Pareto-optimal solution.

    Four main techniques of electromagnetic testing are used for commercial applications: eddy current testing, alternating current field testing, magnetic flux leakage testing and remote field testing. Eddy current testing is a nondestructive evaluation method, which makes eddy current flow on a specimen by applying driving pulse to eddy current probe coil, by using eddy current testing device, and makes the change of eddy current which is dependently caused by flaws, material characteristics, testing condition, receiving through eddy current, and analyzes material properties, flaws, status on the specimen. Application of EC instrumentation varies widely in industry from the identification of metal heat treatment to the inspection of steam generator tubing in nuclear power plants. In this study, we have designed multichannel EC instrument which can be applicable to the NDE of the tube in heat exchanger for electric power facility, chemistry, and military industry, and finally confirmed the proper function of EC instrumentation

    Kim, Bong Goo; Park, Sung Jae; Choo, Ki Nam

    2011-01-01

    Over 50 years of nuclear fuels and materials irradiation testing has led to many countries developing significant improvements in instrumentation to monitor physical parameters and to control the test conditions in Materials Test Reactors (MTRs) or research reactors. Recent effort to deploy new fuels and materials in existing and advanced reactors has increased the demand for well-instrumented irradiation tests. Specifically, demand has increased for tests with sensors capable of providing real-time measurement of key parameters, such as temperature, geometry changes, thermal conductivity, fission gas release, cracking, coating buildup, thermal and fast flux, etc. This review paper documents the current state of instrumentation technologies in MTRs in the world and summarizes on-going research efforts to deploy new sensors. There is increased interest to irradiate new materials and reactor fuels for advanced PWRs and the Gen-IV reactor systems, such as SFRs (Sodium-cooled Fast Reactors), VHTRs (Very-High-Temperature Reactors), SCWRs (Supercritical-Water-cooled Reactors) and GFRs (Gas-cooled Fast Reactor). This review documents the current state of instrumentation technologies in MTRs in the world, identifies challenges faced by previous testing methods and how these challenges were overcome. A wide range of sensors are available to measure key parameters of interest during fuels and materials irradiations in MTRs. Such sensors must be reliable, small size, highly accurate, and able to withstand harsh conditions. On-going development efforts are focusing on providing MTR users a wider range of parameter measurements with increased accuracy. In addition, development efforts are focusing on reducing the impact of sensor on measurements by reducing sensor size. This report includes not only status of instrumentation using research reactors in the world to irradiate nuclear fuels and materials but also future directions relating to instrumentation technologies for

    We have been studying small, driven, magnetic-mirror-based fusion reactors for the Technology Development Facility (TDF), that will test fusion reactor materials, components, and subsystems. Magnetic mirror systems are particularly interesting for this application because of their inherent steady-state operation, potentially high neutron wall loading, and relatively small size. Our design is a tandem mirror device first described by Fowler and Logan, based on the physics of the TMX experiments at Lawrence Livermore National Laboratory (LLNL). The device produces 20 MW of fusion power with a first-wall, uncollided 14-MeV neutron flux of 1.4 MW/m 2 on an area of approximately 8 m 2 , while consuming approximately 250 MW of electrical power. The work was done by a combined industrial-laboratory-university group

    This program is aimed at developing the technology required for carrying out the mirror reactor program. Much of this work applies to the national program and fusion in general; it covers the following areas: Neutral-beam program (including beam direct conversion and vacuum technology). Direct conversion: In addition to direct conversion associated with neutral beams, we have a continuing program to develop efficient direct recovery systems, which are required for reducing power losses from future mirror reactors. Materials program, several key problems on tritium control and handling that must be solved for any large D-T fusion device are being investigated in the LLL tritium laboratory; emphasis is on cleanup of low tritium concentrations in reactor containment buildings and on the containment of tritium by using various low-permeability barriers and coatings to be applied to metal walls. The effects of neutrons on properties of superconducting materials are being investigated using a unique apparatus in which superconducting properties are measured while the specimen is continuously maintained at liquid-helium temperature. Reactor design studies: Design studies of mirror reactors form a basis for evaluation of mirror concepts and for guiding our long-range program. Present emphasis is on delineating features of reactors based on the tandem mirror concept (TMR), on a fission/fusion hybrid reactor based on the TMR, and on an engineering evaluation of a small reactor system based on field reversal. Reactors that are small and candidates for construction the next decade are being investigated in a program sponsored by the Electric Power Research Institute

Nuclear material position scan system for the reduction of measurement error was developed for the spatial distribution search of spent fuel in DUPIC facility. Web-based realtime remote monitoring system was designed and constructed for satisfying the IAEA's performance criteria of continuous monitoring, and also developed a software for the function of remote control and message. And diversion paths in a proliferation resistant pyroprocess for SFR were analyzed and its protecting system against the diversion paths were suggested for enhancing proliferation resistance of advanced nuclear fuel cycle. These results could be used for planning the further R and D items in the area of safeguards. Those R and D results mentioned above would be helpful for increasing Korean nuclear transparency in the future.

    This chapter reviews the parameters which are important to positron-imaging instruments. It summarizes the options which various groups have explored in designing tomographs and the methods which have been developed to overcome some of the limitations inherent in the technique as well as in present instruments. The chapter is not presented as a defense of positron imaging versus single-photon or other imaging modality, neither does it contain a description of various existing instruments, but rather stresses their common properties and problems. Design parameters which are considered are resolution, sampling requirements, sensitivity, methods of eliminating scattered radiation, random coincidences and attenuation. The implementation of these parameters is considered, with special reference to sampling, choice of detector material, detector ring diameter and shielding and variations in point spread function. Quantitation problems discussed are normalization, and attenuation and random corrections. Present developments mentioned are noise reduction through time-of-flight-assisted tomography and signal to noise improvements through high intrinsic resolution. Extensive bibliography. (U.K.)

    Full Text Available Abstract Background Clinical risk management (CRM plays a crucial role in enabling hospitals to identify, contain, and manage risks related to patient safety. So far, no instruments are available to measure and monitor the level of implementation of CRM. Therefore, our objective was to develop an instrument for assessing CRM in hospitals. Methods The instrument was developed based on a literature review, which identified key elements of CRM. These elements were then discussed with a panel of patient safety experts. A theoretical model was used to describe the level to which CRM elements have been implemented within the organization. Interviews with CRM practitioners and a pilot evaluation were conducted to revise the instrument. The first nationwide application of the instrument (138 participating Swiss hospitals was complemented by in-depth interviews with 25 CRM practitioners in selected hospitals, for validation purposes. Results The monitoring instrument consists of 28 main questions organized in three sections: 1 Implementation and organizational integration of CRM, 2 Strategic objectives and operational implementation of CRM at hospital level, and 3 Overview of CRM in different services. The instrument is available in four languages (English, German, French, and Italian. It allows hospitals to gather comprehensive and systematic data on their CRM practice and to identify areas for further improvement. Conclusions We have developed an instrument for assessing development stages of CRM in hospitals that should be feasible for a continuous monitoring of developments in this important area of patient safety.

    2006-01-01

    Molecular imaging using high-resolution single-photon emission computed tomography (SPECT) and positron emission tomography (PET) has advanced elegantly and has steadily gained importance in the clinical and research arenas. Continuous efforts to integrate recent research findings for the design of different geometries and various detector technologies of SPECT and PET cameras have become the goal of both the academic community and nuclear medicine industry. As PET has recently become of more interest for clinical practice, several different design trends seem to have developed. Systems are being designed for ''low cost'' clinical applications, very high-resolution research applications (including small-animal imaging), and just about everywhere in-between. The development of dual-modality imaging systems has revolutionized the practice of nuclear medicine. The major advantage being that SPECT/PET data are intrinsically aligned to anatomical information from the X-ray computed tomography (CT), without the use of external markers or internal landmarks. On the other hand, combining PET with magnetic resonance imaging (MRI) technology is scientifically more challenging owing to the strong magnetic fields. Nevertheless, significant progress has been made resulting in the design of a prototype small animal PET scanner coupled to three multichannel photomultipliers via optical fibers, so that the PET detector can be operated within a conventional MR system. Thus, many different design paths are being pursued - which ones are likely to be the main stream of future commercial systems? It will be interesting, indeed, to see which technologies become the most popular in the future. This paper briefly summarizes state-of-the art developments in nuclear medicine instrumentation. Future prospects will also be discussed. (orig.)

    Spires, Renee H. [Savannah River Remediation (United States)

    2012-07-01

    There are good ideas and new technologies proposed every day to solve problems within the DOE complex. A process to transition a new technology from inception to the decision to launch a project with baselines is described. Examples from active technology development projects within Savannah River Remediation (SRR) will be used to illustrate the points. The process includes decision points at key junctures leading to preliminary design. At that point, normal project management tools can be employed. The technology development steps include proof-of-principle testing, scaled testing and analysis, and conceptual design. Tools are used that define the scope necessary for each step of technology development. The tools include use of the DOE technology readiness guide, Consolidated Hazards Analysis (CHA) and internal checklists developed by Savannah River Remediation. Integration with operating or planned facilities is also included. The result is a roadmap and spreadsheet that identifies each open question and how it may be answered. Performance criteria are developed that enable simple decisions to be made after the completion of each step. Conceptual design tasks should begin as the technology development continues. The most important conceptual design tasks at this point in the process include process flow diagrams (PFDs), high level Process and Instrumentation Drawings (P and IDs), and general layout drawings. These should influence the design of the scaled simulant testing. Mechanical and electrical drawings that support cost and schedule development should also be developed. An early safety control strategy developed from the CHA will also influence the cost. The combination of test results, calculations and early design output with rough order of magnitude cost and schedule information provide input into the decisions to proceed with a project and data to establish the baseline. This process can be used to mature any new technology, especially those that must be

    Full Text Available During the past ten years expertise in human-computer interaction has shifted from humans interacting with desktop computers to individual human beings or groups of human beings interacting with embedded or mobile technology. Thus, humans are not only interacting with computers but with technology. Obviously, this shift should be reflected in how we educate human-technology interaction (HTI experts today and in the future. We tackle this educational challenge first by analysing current Master’s-level education in collaboration with two universities and second, discussing postgraduate education in the international context. As a result, we identified core studies that should be included in the HTI curriculum. Furthermore, we discuss some practical challenges and new directions for international HTI education.

    2012-09-01

    The Advanced Technology Solar Telescope (ATST) is a 4-meter solar observatory under construction at Haleakala, Hawaii. The simultaneous use of multiple instruments is one of the unique capabilities that makes the ATST a premier ground based solar observatory. Control of the instrument suite is accomplished by the Instrument Control System (ICS), a layer of software between the Observatory Control System (OCS) and the instruments. The ICS presents a single narrow interface to the OCS and provides a standard interface for the instruments to be controlled. It is built upon the ATST Common Services Framework (CSF), an infrastructure for the implementation of a distributed control system. The ICS responds to OCS commands and events, coordinating and distributing them to the various instruments while monitoring their progress and reporting the status back to the OCS. The ICS requires no specific knowledge about the instruments. All information about the instruments used in an experiment is passed by the OCS to the ICS, which extracts and forwards the parameters to the appropriate instrument controllers. The instruments participating in an experiment define the active instrument set. A subset of those instruments must complete their observing activities in order for the experiment to be considered complete and are referred to as the must-complete instrument set. In addition, instruments may participate in eavesdrop mode, outside of the control of the ICS. All instrument controllers use the same standard narrow interface, which allows new instruments to be added without having to modify the interface or any existing instrument controllers.

    The role of the Science Mission Directorate (SMD) is to enable NASA to achieve its science goals in the context of the Nation's science agenda. SMD's strategic decisions regarding future missions and scientific pursuits are guided by Agency goals, input from the science community-including the recommendations set forth in the National Research Council (NRC) decadal surveys-and a commitment to preserve a balanced program across the major science disciplines. Toward this end, each of the four SMD science divisions-Heliophysics, Earth Science, Planetary Science, and Astrophysics-develops fundamental science questions upon which to base future research and mission programs. Often the breakthrough science required to answer these questions requires significant technological innovation-e.g., instruments or platforms with capabilities beyond the current state of the art. SMD's targeted technology investments fill technology gaps, enabling NASA to build the challenging and complex missions that accomplish groundbreaking science.

    1997-01-01

    AECL has a comprehensive product development program that is advancing all aspects of CANDU technology including fuel and fuel cycles, fuel channels, heavy water and tritium technology, safety technology, components and systems, constructability, health and environment, and control and instrumentation. The technology arising from these programs is being incorporated into the CANDU design through an evolutionary process. This evolutionary process is focused on improving economics, enhancing safety and ensuring fuel cycle flexibility to secure fuel supply for the foreseeable future. This strategic thrusts are being used by CANDU designers and researchers to set priorities and goals for AECL's development activities. The goals are part of a 25-year development program that culminates in the 'CANDU X'. The 'CANDU X' is not a specific design - it is a concept that articulates our best extrapolation of what is achievable with the CANDU design over the next 25 years, and includes the advanced features arising from the R and D and engineering to be done over that time. AECL's current product, the 700 MWe class CANDU 6 and the 900 MWe class CANDU 9, both incorporate output from the development programs as the technology become available. A brief description of each development areas is given below. The paper ends with the conclusion that AECL has a clear vision of how CANDU technology and products will evolve over the next several years, and has structured a comprehensive development program to take full advantage of the inherent characteristics of heavy water reactors.

    2014-01-01

    A review of existing measurement instruments was conducted to examine their suitability to measure disability prevalence and assess quality of life, protection of disability rights and community participation by people with disabilities, specifically within the context of development programs in low and middle-income countries. From a search of PubMed and the grey literature, potentially relevant measurement instruments were identified and examined for their content and psychometric properties, where possible. Criteria for inclusion were: based on the WHO's International Classification of Functioning Disability and Health (ICF), used quantitative methods, suitable for population-based studies of disability inclusive development in English and published after 1990. Characteristics of existing instruments were analysed according to components of the ICF and quality of life domains. Ten instruments were identified and reviewed according to the criteria listed above. Each version of instruments was analysed separately. Only three instruments included a component on quality of life. Domains from the ICF that were addressed by some but not all instruments included the environment, technology and communication. The measurement instruments reviewed covered the range of elements required to measure disability-inclusion within development contexts. However no single measurement instrument has the capacity to measure both disability prevalence and changes in quality of life according to contemporary disability paradigms. The review of measurement instruments supports the need for developing an instrument specifically intended to measure disability inclusive practice within development programs. Implications for Rehabilitation Surveys and tools are needed to plan disability inclusive development. Existing measurement tools to determine prevalence of disability, wellbeing, rights and access to the community were reviewed. No single validated tool exists for population

    1994-01-01

    For the period 1987-1993, developments in the environmental policies of OECD countries with respect to the use of economic instruments are compared and the differences analyzed. The focus is on applications in the field of air pollution policies. The comparison is made on the basis of two surveys. To complete the descriptive part, a brief survey is also presented of currently discussed and recently introduced economic instruments. A description of economic instruments as such and a review of rationales for employing economic and financial incentives precede this analysis. The analysis shows that the use of economic instruments has indeed increased since 1987, but the development has not been spectacular. Possible explanations for this are presented. Also, some types of instrument have advanced more than others and the changes differ from one set of countries to another. Product charges (including air pollution-related ones) have become more widely used, especially in Scandinavian countries. Moreover, growing attention is being paid to the use of economic instruments at the international level. The incentive impacts of economic (and other) instruments appear to have received relatively little empirical attention, even though these are an important policy-relevant feature in instrument choice. 23 refs., 5 tabs

    2011-05-01

    Full Text Available As one of the oldest instruments known to mankind, the flute is present in some form in nearly every culture and ethnic group in the world. However, in Western music in particular, the flute has taken its place as an important part of musical culture, both as a solo and an ensemble instrument. The flute has also undergone its most significant technological developments in Western musical culture, moving from the bone keyless flutes of the Prehistoric era to the gold and silver instruments known to performers today. During the Renaissance and Baroque periods in particular, however, the flute rose to popularity as a solo instrument and began to evolve into its modern form. New developments in the design and mechanics of the instrument drove this increased interest, which ultimately gave the flute a prominent position in music that has lasted throughout history.

    This second chapter on instrumentation gives little general consideration on history and classification of instrumentation, and two specific states of the art. The first one concerns NMR (block diagram of instrumentation chain with details on the magnets, gradients, probes, reception unit). The first one concerns precision instrumentation (optical fiber gyro-meter and scanning electron microscope), and its data processing tools (programmability, VXI standard and its history). The chapter ends with future trends on smart sensors and Field Emission Displays. (D.L.). Refs., figs

    ``Squeezing'' of the stone or cirumferential pressure of the wave propagating at the outside of the stone in the liquid or tissue results in fragmentation in planes perpendicular or parallel to the wave propagation direction. The corresponding pressure zone propagating with the sound velocity in the liquid which is below the sound velocity in the stone, causes an evanescent pressure zone in the stone resulting in tensile stress in planes parallel and perpendicular to the wave plane. A quantitative model predicting the ratio of pulses needed to fragment the stone to 2 mm particle size in relation to the number of pressure pulses needed for the first fragmentation is well in accord with experiments, supporting the ``squeezing mechanism with binary fragmentation.'' On the basis of these results it now appears possible to optimize the pressure pulse parameters measured using the Fiber Optic Probe Hydrophone (FOPH). With correspondingly optimized self-focusing electromagnetic shock wave generator systems a clinical study of the concept ``wide focus and low pressure'' ESWL was performed in a scientific cooperation between the 1. Physical Institute of the University of Stuttgart and the Xixin Medical Instruments Co., Ltd. in Suzhou, China. Literature: W.

    The new industrial political tools based on the sustainable development of productive activities, and originating at the Rio Conference in 1992, late introduced by the EU, the Government and voluntary organizations (ISO, CEM, UNI) are gradually entering the market, thereby underling their effect in terms of industrial competitiveness. The main tools were examined in the report and mostly refer to the voluntary ones which, in surpassing the 'command and control' logic, increasingly tend to get close to traditional fiscal, tariff and financial ones. Voluntary agreements, environmental management systems (EMAS, norme ISO 14001), the risk prevention systems (UNI 10617), certification (Ecolabel, ISO 14040) and environment communication tools (environment balance sheet, environmental report, environmental statement) are synthetically described [it

    Heavy water is used as a moderator and heat transport medium in CANDU reactors. It is a very expensive component of the reactor and any leaking or downgrading serves to increase the cost of electric power. Precise analytical measurements of the isotopic concentrations of water samples over the entire range of D 2 O concentrations are therefore vital for keeping such leaking or downgrading to a minimum. On-line isotopic analyzers offer many advantages over manual sampling; timely protection against leaks to the environment, continuous rather than discrete data for process control, accurate accounting for heavy water inventory, reduction in staff workloads, operational convenience and cost saving. This article outlines Chalk River Nuclear Laboratories' combined endeavours with Barringer Research Limited to find a viable approach to on-line D 2 O monitoring at CANDU power stations and heavy water plants. The development of heavy water monitors from their initial design, the Series 400 monitors, to their current one, the Series 4600, is traced

    Full Text Available Innovation is seen in numerous specialized studies as an efficient method for improving the performance of a company based on the sector in which that company operates. Based on this idea, the article aims to determine the nature of inter-correlation between the innovation activity of companies and the level of performance of these, which are the main types of innovation and how they can influence companies` position and how the sector of activity can influence the dimension of the impact of innovation. For achieve these objectives have been analysed empirical studies in various sectors, studies which have highlighted a positive inter-correlation between innovation activity and the performance of companies with significant differences depending on the type of innovation and industry use. The article is completed by an empirical analysis which aims to determine the extent to which performance of companies in the construction sector is sensitive to innovation activity. For the analysis were collected data from 14 companies which developed the specific activities in the construction sector of Europe, were achieve a total of 112 observations. The results obtained by applying a multiple regression model shows a positive correlation relationship between indicators of innovation (R&D expenditures and the value of patents/patents on the one side and performance indicators (equity, labour productivity and number of employees on the other side. Another direction of research analysed in this paper is to determine the impact of labour indicators on the level of innovation, in this situation was achieve a positive but insignificant inter-correlation between those indicators.

    Transfer of technology is a complex process with many facets, options and constraints. While the concept is an important step in bringing industrialization process to agricultural based countries, it is clear, however, that a country will only benefit from a new technology if it addresses a real need, and if it can be absorbed and adapted to suit the existing cultural and technological base. International Atomic Energy Agency, as UN body, has a mandate to promote nuclear applicationsand assist Member States in transfer of technology for peaceful applications. This mandate has been pursued by many different mechanisms developed in the past years: technical assistance, coordinated research programmes, scientific and technical meetings, publications, etc. In all these activities the Agency is the organizer and initiator, but main contributions come from expert services from developed countries and, increasingly, from developing countries themselves. The technical cooperation among developing coutries more and more becomes part of different programmes. In particular, regional cooperation has been demonstrated as an effective instrument for transfer of technology from developed and among developing countries. Some examples of actual programmes are given.

    This contribution will describe the initial stages of a new ASTID-funded research program initiated in Fall 2009 aimed at lab-on-a-chip system development for astrobiological investigations on Titan. This technology development builds off related work at JPL and Berkeley [1-3] on the ultrasensitive compositional and chiral analysis of amino acids on Mars in order to search for signatures of past or present life. The Mars-focused instrument system utilizes a microcapillary electrophoresis (μCE) system integrated with on-chip perfluoropolyether (PFPE) membrane valves and pumps for automated liquid sample handling, on-chip derivitization of samples with fluorescent tags, dilution, and mixing with standards for data calibration. It utilizes a four-layer wafer stack design with CE channels patterned in glass, along with a PFPE membrane, a pneumatic manifold layer, and a fluidic bus layer. Three pneumatically driven on-chip diaphragm valves placed in series are used to peristaltically pump reagents, buffers, and samples to and from capillary electrophoresis electrode well positions. Electrophoretic separation occurs in the all-glass channels near the base of the structure. The Titan specific lab-on-a-chip system under development here focuses its attention on the unique organic chemistry of Titan. In order to chromatographically separate mixtures of neutral organics such as polycyclic aromatic hydrocarbons (PAHs), the Titan-specific microfluidic platform utilizes the related technique of microcapillary electrochromatography (μCEC). This technique differs from conventional μCE in that microchannels are filled with a porous stationary phase that presents surfaces upon which analyte species can adsorb/desorb. It is this additional surface interaction that enables separations of species critical to the understanding of the astrobiological potential of Titan that are not readily separated by the μCE technique. We have developed two different approaches for the integration

  16. Mobilizing technology for developing countries

    Weiss, C Jr

    1979-10-01

    Mr. Weiss says that the 15 years since the UN Conference on Science, Technology, and Development in Geneva have taught us that what seem at first to be technological obstacles to development frequently turn out on closer examination to have been policy failures; that introduction of technologies into developing countries must be accompanied by institutional and policy changes if the technologies are to benefit the countries. He points out that choice of alternative technology for a developing country should depend on careful overall assessment of local techno-economic, geographical, ecological, and social factors, as well as the desired balance between growth and equity. Such a technology assessment, a key element in the choice of appropriate (i.e., locally suitable) technology for particular investment projects, should be built into procedures for project preparation and appraisal in governments and development assistance agencies. Turning to technologists, Mr. Weiss says they face a double challenge: (1) to recognize potential for new efforts to harness science and technology for the benefit of the developing countries; and (2) by understanding the social, institutional, and economic framework into which an innovation is to operate, to ease its application and diffusion, and thus speed and increase its practical impact. 25 references.

    Adequate work assessments are a matter of importance both for individuals and society [5,29,31,38,40,46,52]. However, there is a lack of adequate and reliable instruments for use in work rehabilitation [14,15,20,21,31,44]. The purpose of this study was to develop and evaluate an observation instrument for assessing work performance, the AWP (Assessment of Work Performance). The purpose of the 14-item instrument is to assess the individual's observable working skills in three different areas: motor skills, process skills, and communication and interaction skills. This article describes the development and results of preliminary testing of the AWP. The testing indicates a satisfactory face validity and utility for the AWP and supports further research and testing of the instrument.

In the fourth Stage (reliability study, eight raters assessed thirty randomly selected decision support technologies.IPDASi measures quality in 10 dimensions, using 47 items, and provides an overall quality score (scaled from 0 to 100 for each intervention. Overall IPDASi scores ranged from 33 to 82 across the decision support technologies sampled (n = 30, enabling discrimination. The inter-rater intraclass correlation for the overall quality score was 0.80. Correlations of dimension scores with the overall score were all positive (0.31 to 0.68. Cronbach's alpha values for the 8 raters ranged from 0.72 to 0.93. Cronbach's alphas based on the dimension means ranged from 0.50 to 0.81, indicating that the dimensions, although well correlated, measure different aspects of decision support technology quality.

    Full Text Available This paper shows the results of studying the technology of manufacturing cortical electrode-instruments (EI with the use of indirect methods of the Rapid Prototyping technology. Functional EI prototypes were made by layered synthesis of the photopolymer material with the use of the stereolithography technology (SLA - Stereo Lithography Apparatus. The article is focused on two methods of indirect EI manufacturing. One of the EI prototypes was used for making a molded wax model for hot investment casting, followed by applying copper coating. The second prototype was used for applying copper plating to a prepared current-conductive layer. As a result of EDMing a steel workpiece, both EIs reached the desired depth, which is 1 mm. The copper plating applied to the EI preserves its integrity. Through the use of the casting technology, there is a possibility to cut the economic costs by 35%. Using a prototype with preliminarily applied conductive coating makes it possible to make geometrically-complex EIs.

    Full Text Available  Future skills, so-called 21st century skills, emphasise collaboration, creativity, critical thinking, problem-solving and especially ICT skills (Voogt & Roblin, 2012. Teachers have to be able to use various pedagogical approaches and ICT in order to support the development of their students’ 21st century skills (Voogt & Roblin, 2012. These skills, particularly ICT skills, pose challenges for teachers and teacher education. This paper focuses on developing an instrument for measuring pre-service teachers’ knowledge related to ICT in the context of 21st century skills.Technological Pedagogical Content Knowledge (TPACK; Mishra & Kohler, 2006 was used as a theoretical framework for designing the instrument. While the TPACK framework is actively used, the instruments used to measure it have proven challenging. This paper outlines the results of the development process of the TPACK-21 instrument. A new assessment instrument was compiled and tested on pre-service teachers in Study1 (N=94. Based on these results, the instrument was further developed and tested in Study2 (N=267. The data of both studies were analysed using multiple quantitative methods in order to evaluate the psychometric properties of the instruments. The results provide insight into the challenges of the development process itself and also suggest new solutions to overcome these difficulties.

    In this review article, we summarize systems for gait rehabilitation based on instrumented footwear and present a context of their usage in Parkinson's disease (PD) patients' auditory and haptic rehabilitation. We focus on the needs of PD patients, but since only a few systems were made with this purpose, we go through several applications used in different scenarios when gait detection and rehabilitation are considered. We present developments of the designs, possible improvements, and software challenges and requirements. We conclude that in order to build successful systems for PD patients' gait rehabilitation, technological solutions from several studies have to be applied and combined with knowledge from auditory and haptic cueing.

    Modern and future heterodyne radio astronomy instrumentation critically depends on availability of advanced fabrication technologies and components. In Part1 of the Poster, we present the thin film fabrication process for SIS mixer receivers, utilizing either AlOx, or AlN barrier superconducting tunnel junctions developed and supported by GARD. The summary of the process design rules is presented. It is well known that performance of waveguide mixer components critically depends on accuracy of their geometrical dimensions. At GARD, all critical mechanical parts are 3D-mapped with a sub-um accuracy. Further progress of heterodyne instrumentation requires new efficient and compact sources of LO signal. We present SIS-based frequency multiplier, which could become a new option for LO source. Future radio astronomy THz receivers will need waveguide components, which fabricating due to their tiny dimensions is not feasible by traditional mechanical machining. We present the alternative micromachining technique for fabricating waveguide component for up 5 THz band and probably beyond.

    1989-01-01

    The author develops a general set of considerations to explain how a consistent, well-organized, prioritized, and adequate time-allowance program plan for routine maintenance can be constructed. The analysis is supplemented with experience from the high flux isotope reactor (HFIR) at US Oak Ridge National Laboratory (ORNL). After the preventive maintenance (PM) problem was defined, the instruments on the schedule were selected based on the manufacturer's design specifications, quality-assurance requirements, prior classifications, experiences with the incidence of breakdowns or calibration, and dependencies among instruments. The effects of repair error in PM should be also studied. The HFIR requires three full-time technicians to perform both PM and unscheduled maintenance. A review is presented of concepts from queuing theory to determine anticipated breakdown patterns. In practice, the pneumatic instruments have a much longer lifetime than the electric/electronic instruments on various reactors at ORNL.

    A radioactive aerosol instrumentation is developed recently for measuring the α and/or β activity of artificial radioactivity aerosols which are produced in nuclear facilities. The instrumentation has the function discriminating natural radioactivity aerosols resulted from radon and thoron daughters, and it is enabled in time and without delay to measure α and β artificial activity collected with a filter by pumping aerosols through this filter. The energy discrimination and compensation method is used for eliminating the influence of natural αradioactivity aerosols. To minimize the influence of natural β-radioactivity aerosols, the method measuring the ratio α/β of natural aerosols is also used in the instrument. The improved methods eliminating the influence of natural background α and β aerosols are used so that both α and β artificial activities in aerosol filter samples can be monitored simultaneously. The instrumentation is appropriate for monitoring α and/or β artificial radioactive aerosols

    Liu, P; Tian, W Y

    2006-01-01

    A model machine of multifunctional form and position measurement instrument controlled by a personal computer has been successfully developed. The instrument is designed in rotary table type with a high precision air bearing and the radial rotation error of the rotary table is 0.08 μm. Since a high precision vertical sliding carriage supported by an air bearing is used for the instrument, the straightaway motion error of the carriage is 0.3 μm/200 mm and the parallelism error of the motion of the carriage relative to the rotation axis of the rotary table is 0.4 μm/200 mm. The mathematical models have been established for assessing planar and spatial straightness, flatness, roundness, cylindricity, and coaxality errors. By radial deviation measurement, the instrument can accurately measure form and position errors of such workpieces as shafts, round plates and sleeves of medium or small dimensions with the tolerance grades mostly used in industry

  16. Recent Developments in Instrumentation for Pre-Clinical Imaging Studies

    Full text: Recent advances in imaging instrumentation have led to a variety of tomograph designs for dedicated pre clinical imaging of laboratory animals. These advances make it possible to image and quantify the kinetics of radiolabelled pharmaceuticals in a wide range of animal models from rodents to non-human primates. Applications include evaluation of promising new radiopharmaceuticals, study of the molecular origins of human disease and evaluation of new forms of therapy. These applications and advances in instrumentation are equally applicable to positron emitters and single photon emitters. This paper provides an overview of recent advances which have led to the current state-of-the-art in pre clinical imaging. The common inorganic scintillators that have been used for SPECT and PET, including some of the promising materials recently studied. The current crystal of choice for SPECT imaging is NaI(Tl) because of its high light output and density which make it well suited to imaging photons in the 100-200 keV range. However, NaI(Tl) has the disadvantage that it must be hermetically sealed to prevent absorption of moisture from the environment. Therefore, investigators have explored a number of alternative inorganic crystals, including CsI(Tl) and cerium-doped yttrium aluminium perovskite (YAP), as well as solid state detectors such as cadmium zinc telluride (CZT). Many of the crystals used in SPECT have also been tried for PET, including NaI(Tl) and YAP. However these crystals have lower stopping power than BGO and NaI(Tl) is also relatively slow. A very promising scintillator for PET is cerium-doped lutetium oxyorthosilicate (LSO) (1) which has similar stopping power to BGO and relatively high light output and fast decay. The first PET scanner to use LSO was the UCLA animal scanner, microPET, which also makes use of a number of other new technologies and unique design features. Recently, improvements in multi-anode and crossed wire position sensitive

    This is the final report of a one-year, Laboratory Directed Research and Development (LDRD) project at Los Alamos National Laboratory (LANL). A Multichip Module (MCM) was designed and submitted for fabrication to the Lockheed Martin foundry using a licensed process called High Density Interconnect (HDI). The HDI process uses thin film techniques to create circuit interconnect patterns on multiple layers of dielectric film which are deposited directly on top of unpackaged electronic die. This results in an optimally small package that approaches the area of the bare die themselves. This project tested the capability of the Lockheed Martin foundry to produce, in an HDI process, a complex mixed-mode (analog and digital) circuit on a single MCM substrate

    Tsuda, Kenzo; Ito, Emi.

    1985-08-01

    In order to computerize the lending and management of measuring instruments, at first, the specification of the software was examined, but thereafter, the development was begun. The largest aim of the computerization was the automation and labor saving of the lending works of diverse measuring instruments and the automatic management. From user side, it is desirable to know the specification and the state of use and reservation of measuring instruments and to be able to easily make reservation based on the information. Besides, from management side, it is desirable to know the location and the state of use and reservation of measuring instruments, to immediately prepare for lending and returning, and to automate the recording of lending and returning. So as to satisfy those conditions, the automatic reservation and management system for measuring instruments was developed. At the same time, the means to simply input required data such as specification, names of manufacturers and equipment number was developed. The input of data was carried out for three months from October, 1984, and the system was almost completed in December, 1984. The full scale operation was started in Junuary, 1985. (Kako, I.)

    The purpose of this study is to develop and validate the Korean Health Literacy Instrument, which measures the capacity to understand and use health-related information and make informed health decisions in Korean adults. In Phase 1, 33 initial items were generated to measure functional, interactive, and critical health literacy with prose, document, and numeracy tasks. These items included content from health promotion, disease management, and health navigation contexts. Content validity assessment was conducted by an expert panel, and 11 items were excluded. In Phase 2, the 22 remaining items were administered to a convenience sample of 292 adults from community and clinical settings. Exploratory factor and item difficulty and discrimination analyses were conducted and four items with low discrimination were deleted. In Phase 3, the remaining 18 items were administered to a convenience sample of 315 adults 40-64 years of age from community and clinical settings. A confirmatory factor analysis was performed to test the construct validity of the instrument. The Korean Health Literacy Instrument has a range of 0 to 18. The mean score in our validation study was 11.98. The instrument exhibited an internal consistency reliability coefficient of 0.82, and a test-retest reliability of 0.89. The instrument is suitable for screening individuals who have limited health literacy skills. Future studies are needed to further define the psychometric properties and predictive validity of the Korean Health Literacy Instrument.

    The Office of Technology Development (TD) supports research and development of technologies that will lower cost, reduce risk, improve safety, and accelerate cleanup of the Nuclear Weapons Complex and provide solutions to currently untractable environmental problems. The TD strategic plan outlines Applied Research, Development, Demonstration, Testing, and Evaluation (RDDT and E) that will provide needed technology products to be used by Environmental Restoration and Waste Management operations (i.e., our customers). The TD strategic plan is derived from EM Goals, Objectives, and Strategy and is incorporated into DOE'S Five-Year Plan for Environmental Restoration and Waste Management. The TD strategic plan is developed based on integrating customer requirements, and is complemented by a top-down, bottom-up analysis of Site Specific Technology Needs and environmental problems. The execution of TD's strategic plan is implemented largely through Integrated Programs (IP) and Integrated Demonstrations (ID). IDs have proven to be a cost-effective method of managing technology development, testing and evaluation, and implementation of successful technology systems into the DOE Environmental Restoration and Waste Management Programs. The Savannah River ID for Volatile Organic Compounds (VOCs) in Saturated Soils resulted in a 51 percent cost savings over stand-alone demonstrations, saving over $8 million. The IPs and IDs are selected based on customer needs, technical complexity, and complex-wide regulatory and compliance agreements. New technology systems are selected for incorporation into an IP or ID from offerings of the DOE laboratories, industry, and the universities. A major TD initiative was announced in August 1991, with the release of a Program Research and Development Announcement (PRDA) requesting industry and universities to propose innovative new technologies to clean up the Weapons Complex.

    Near infrared spectroscopy (NIRS) is an established technology using photons of light in the near infrared spectrum to monitor changes in tissue of naturally occurring chromophores, including oxygenated and deoxygenated hemoglobin. Technology and methodology have been validated for measurement of a range of physiologic parameters. NIRS has been applied successfully in urology research; however current instruments are designed principally for brain and muscle study. To describe development of a NIRS instrument specifically designed for monitoring changes in chromophore concentration in the bladder detrusor in real time, to facilitate research to establish the role of this non-invasive technology in the evaluation of patients with voiding dysfunction The portable continuous wave NIRS instrument has a 3 laser diode light source (785, 808 and 830 nanometers), fiber optic cables for light transmission, a self adhesive patient interface patch with an emitter and sensor, and software to detect the difference between the light transmitted and received by the instrument. Software incorporated auto-attenuates the optical signals and converts raw optical data into chromophore concentrations displayed graphically. The prototype was designed, tested, and iteratively developed to achieve optimal suprapubic transcutaneous monitoring of the detrusor in human subjects during bladder filling and emptying. Evaluation with simultaneous invasive urodynamic measurement in men and women indicates good specificity and sensitivity of NIRS chromophore concentration changes by receiver operator curve analysis, and correlation between NIRS data and urodynamic pressures. Urological monitoring with this NIRS instrument is feasible and generates data of potential diagnostic value.

    The COR and PCOS Program Offices (POs) reside at the NASA Goddard Space Flight Center (GSFC), serving as the NASA Astrophysics Division's implementation arm for matters relating to the two programs. One aspect of the PO's activities is managing the COR and PCOS Strategic Astrophysics Technology (SAT) program, helping mature technologies to enable and enhance future astrophysics missions. For example, the SAT program is expected to fund key technology developments needed to close gaps identified by Science and Technology Definition Teams (STDTs) planned to study several large mission concept studies in preparation for the 2020 Decadal Survey.The POs are guided by the National Research Council's "New Worlds, New Horizons in Astronomy and Astrophysics" Decadal Survey report, NASA's Astrophysics Implementation Plan, and the visionary Astrophysics Roadmap, "Enduring Quests, Daring Visions." Strategic goals include dark energy, gravitational waves, and X-ray observatories. Future missions pursuing these goals include, e.g., US participation in ESA's Euclid, Athena, and L3 missions; Inflation probe; and a large UV/Optical/IR (LUVOIR) telescope.To date, 65 COR and 71 PCOS SAT proposals have been received, of which 15 COR and 22 PCOS projects were funded. Notable successes include maturation of a new far-IR detector, later adopted by the SOFIA HAWC instrument; maturation of the H4RG near-IR detector, adopted by WFIRST; development of an antenna-coupled transition-edge superconducting bolometer, a technology deployed by BICEP2/BICEP3/Keck to measure polarization in the CMB signal; advanced UV reflective coatings implemented on the optics of GOLD and ICON, two heliophysics Explorers; and finally, the REXIS instrument on OSIRIS-REx is incorporating CCDs with directly deposited optical blocking filters developed by another SAT-funded project.We discuss our technology development process, with community input and strategic prioritization informing calls for SAT proposals and

  17. Multi-Institutional Development of a Mastoidectomy Performance Evaluation Instrument.

    Kerwin, Thomas; Hittle, Brad; Stredney, Don; De Boeck, Paul; Wiet, Gregory

    A method for rating surgical performance of a mastoidectomy procedure that is shown to apply universally across teaching institutions has not yet been devised. This work describes the development of a rating instrument created from a multi-institutional consortium. Using a participatory design and a modified Delphi approach, a multi-institutional group of expert otologists constructed a 15-element task-based checklist for evaluating mastoidectomy performance. This instrument was further refined into a 14-element checklist focusing on the concept of safety after using it to rate a large and varied population of performances. Twelve otolaryngological surgical training programs in the United States. A total of 14 surgeons from 12 different institutions took part in the construction of the instrument. By using 14 experts from 12 different institutions and a literature review, individual metrics were identified, rated as to the level of importance and operationally defined to create a rating scale for mastoidectomy performance. Initial use of the rating scale showed modest rater agreement. The operational definitions of individual metrics were modified to emphasize "safe" as opposed to "proper" technique. A second rating instrument was developed based on this feedback. Using a consensus-building approach with multiple rounds of communication between experts is a feasible way to construct a rating instrument for mastoidectomy. Expert opinion alone using a Delphi method provides face and content validity evidence, however, this is not sufficient to develop a universally acceptable rating instrument. A continued process of development and experimentation to demonstrate evidence for reliability and validity making use of a large population of raters and performances is necessary to achieve universal acceptance.

    2017-12-01

    Titanium aluminide alloys have been successfully introduced into civil aircraft engine technology in recent years, and a significant order volume increase is expected in the near future. Due to its beneficial buy-to-fly ratio, investment casting bears the highest potential for cost reduction of all competing production technologies for TiAl-LPTB. However, highest mechanical properties can be achieved by TiAl forging. In view of this, Access e.V. has developed technologies for the production of TiAl investment cast parts and TiAl die cast billets for forging purposes. While these parts meet the highest requirements, establishing series production and further optimizing resource and economic efficiency are present challenges. In order to meet these goals, Access has recently been certified according to aircraft standards, aiming at qualifying parts for production on technology readiness level 6. The present work gives an overview of the phases of development and certification.

    This article explores the extent to which and in what ways environmental policy instruments may affect patterns of environmental friendly technological change in the energy sector. Our argument is based on the assumption, however, that technological change is also affected by the political context in which the instruments are applied and by the nature of the problem itself. Comparative empirical research involving different European countries, sectors and policy fields were examined, including climate change, air pollution and wind power. The relationship between environmental policy instruments and technological change is extremely complex, not least due to the impact of other factors that may be more decisive than environmental ones. Against this backdrop, it was concluded that: 1) a portfolio of policy instruments works to the extent that different types of policy instruments affect the different drivers and stages behind technological change needed to solve specific problems. The need for a portfolio of policy instruments depends on the technological challenge being faced; 2) voluntary approaches facilitated constructive corporate strategies, but mandatory approaches tended to be more effective in stimulating short term major technological change; 3) voluntary approaches work well in the short term when the problem to be solved is characterized by lack of information and coordination.

  5. Fact sheet on nuclear power plant instrumentation and control technologies

    International Nuclear Information System (INIS)

    2006-01-01

    Nuclear power plants (NPPs) are facing challenges in several instrumentation and control (I and C) areas with ageing and obsolete components and equipment. With license renewals and power uprates, the long-term operation and maintenance of obsolete I and C systems may not be a cost-effective and reliable option. The effort needed to maintain or increase the reliability and useful life of existing I and C systems may be greater in the long run than modernizing I and C systems or replacing them completely with new digital systems. The increased functionality of the new I and C systems can also open up new possibilities to better support the operation and maintenance activities in the plant. The IAEA recognizes the importance of the profound role the I and C systems play in the reliable, safe, efficient, and cost-effective operations of NPPs by supporting the activities of the Department of Nuclear Energy's Technical Working Group on Nuclear Power Plant Control and Instrumentation (TWG-NPPCI). The group was established in March 1970. Its membership currently includes thirty Member States and three international organizations. The most recent meeting of the TWG-NPPCI was held in May 2005 in Vienna. The meeting report is available at http://www.iaea.org/OurWork/ST/NE/NENP/twg_nppc.html. The next meeting of the TWGNPPCI will be the 21st meeting of the advisory body, and it will be held in May 2007

    A set of prototype, high temperature logging tools (temperature, pressure and flow) were tested successfully to temperatures up to 275/sup 0/C in a Union geothermal well during November 1978 as part of the Geothermal Logging Instrumentation Development Program. This program is being conducted by Sandia Laboratories for the Department of Energy's Division of Geothermal Energy. The progress and plans of this industry based program to develop and apply the high temperature instrumentation technology needed to make reliable geothermal borehole measurements are described. Specifically, this program is upgrading existing sondes for improved high temperature performance, as well as applying new materials (elastomers, polymers, metals and ceramics) and developing component technology such as high temperature cables, cableheads and electronics to make borehole measurements such as formation temperature, flow rate, high resolution pressure and fracture mapping. In order to satisfy critical existing needs, the near term goal is for operation up to 275/sup 0/C and 7000 psi by the end of FY80. The long term goal is for operation up to 350/sup 0/C and 20,000 psi by the end of FY84.

  14. Applications of telecommunication technology for optical instrumentation with an emphasis on space-time duality

    Science.gov (United States)

    van Howe, James William

    Telecommunication technology has often been applied to areas of science and engineering seemingly unrelated to communication systems. Innovations such as electronic amplifiers, the transistor, digital coding, optical fiber, and the laser, which all had roots in communication technology, have been implemented in devices from bar-code scanners to fiber endoscopes for medical procedures. In the same way, the central theme of the work in the following chapters has been to borrow both the concepts and technology of telecommunications systems to develop novel optical instrumentation for non-telecom pursuits. This work particularly leverages fiber-integrated electro-optic phase modulators to apply custom phase profiles to ultrafast pulses for control and manipulation. Such devices are typically used in telecom transmitters to encode phase data onto optical pulses (differential phase-shift keying), or for chirped data transmission. We, however, use electro-optic phase modulators to construct four novel optical devices: (1) a programmable ultrafast optical delay line with record scanning speed for applications in optical metrology, interferometry, or broad-band phase arrays, (2) a multiwavelength pulse generator for real-time optical sampling of electronic waveforms, (3) a simple femtosecond pulse generator for uses in biomedical imaging or ultrafast spectroscopy, and (4) a nonlinear phase compensator to increase the energy of fiber-amplified ultrashort pulse systems. In addition, we describe a fifth instrument which makes use of a higher-order mode fiber, similar in design to dispersion compensating fibers used for telecom. Through soliton self-frequency shift in the higher-order mode fiber, we can broadly-tune the center frequency of ultrashort pulses in energy regimes useful for biomedical imaging or ultrafast spectroscopy. The advantages gained through using telecom components in each of these systems are the simplicity and robustness of all-fiber configurations, high

    There is a strong need for portable radiometric instrumentation that can accurately confirm the presence of nuclear materials and allow isotopic analysis of radionuclides in the field. To fulfill this need, the authors are developing a hand-held, non-cryogenic, low-power gamma- and X-ray measurement and analysis instrument that can both search and then accurately verify the presence of nuclear materials. The authors report on the use of cadmium zinc telluride detectors, signal processing electronics, and the new field-portable instrument based on the MicroNOMAD Multichannel Analyzer from EG and G ORTEC. They will also describe the isotopic analysis that allows uranium enrichment measurements to be made accurately in the field. The benefits of this work are realized in a wide spectrum of applications that include Arms Control, Nuclear Safeguards, Environmental Management, Emergency Response, and Treaty Verification

    Radiation therapy machines need a constant monitoring to assure tumoral dose accuracy. Special attention must be given to linear accelerators which should be checked frequently. By this reason, an instrument was developed at the Nuclear Instrumentation Laboratory DEN/UFPE to measure the output energy and beam symmetry. This instrument use three silicon photodiodes as radiation detectors. Two of then were localized at 5cm and 10cm depht at the central axis and one at 5 cm from the center, at the lateral irradiated field. Changes in the photon spectrum are detected by the ratio of upper to lower photodiode response. The radiation field uniformity is checked by the lateral photodiode. (author) [pt

    Pyroprocessing technology was developed in the beginning for metal fuel treatment in the US in the 1960s. The conventional aqueous process, such as PUREX, is not appropriate for treating metal fuel. Pyroprocessing technology has advantages over the aqueous process: less proliferation risk, treatment of spent fuel with relatively high heat and radioactivity, compact equipment, etc. The addition of an oxide reduction process to the pyroprocessing metal fuel treatment enables handling of oxide spent fuel, which draws a potential option for the management of spent fuel from the PWR. In this context, KAERI has been developing pyroprocessing technology to handle the oxide spent fuel since the 1990s. This paper describes the current status of pyroprocessing technology development at KAERI from the head-end process to the waste treatment. A unit process with various scales has been tested to produce the design data associated with the scale up. A performance test of unit processes integration will be conducted at the PRIDE facility, which will be constructed by early 2012. The PRIDE facility incorporates the unit processes all together in a cell with an Ar environment. The purpose of PRIDE is to test the processes for unit process performance, operability by remote equipment, the integrity of the unit processes, process monitoring, Ar environment system operation, and safeguards related activities. The test of PRIDE will be promising for further pyroprocessing technology development

    The 2020 Decadal technology survey is starting in 2018. Technology on the shelf at that time will help guide selection to future low risk and low cost missions. The Advanced Mirror Technology Development (AMTD) team has identified development priorities based on science goals and engineering requirements for Ultraviolet Optical near-Infrared (UVOIR) missions in order to contribute to the selection process. One key development identified was lightweight mirror fabrication and testing. A monolithic, stacked, deep core mirror was fused and replicated twice to achieve the desired radius of curvature. It was subsequently successfully polished and tested. A recently awarded second phase to the AMTD project will develop larger mirrors to demonstrate the lateral scaling of the deep core mirror technology. Another key development was rapid modeling for the mirror. One model focused on generating optical and structural model results in minutes instead of months. Many variables could be accounted for regarding the core, face plate and back structure details. A portion of a spacecraft model was also developed. The spacecraft model incorporated direct integration to transform optical path difference to Point Spread Function (PSF) and between PSF to modulation transfer function. The second phase to the project will take the results of the rapid mirror modeler and integrate them into the rapid spacecraft modeler.

    2001-01-01

    The Electron Drift Instrument (EDI) is a new technique for measuring electric fields in space by detecting the effect on weak beams of test electrons. This U.S. portions of the technique, flight hardware, and flight software were developed for the Cluster mission under this contract. Dr. Goetz Paschmann of the Max Planck Institute in Garching, Germany, was the Principle Investigator for Cluster EDI. Hardware for Cluster was developed in the U.S. at the University of New Hampshire, Lockheed Palo Alto Research Laboratory, and University of California, San Diego. The Cluster satellites carrying the original EDI instruments were lost in the catastrophic launch failure of first flight of the Arianne-V rocket in 1996. Following that loss, NASA and ESA approved a rebuild of the Cluster mission, for which all four satellites were successfully launched in the Summer of 2000. Limited operations of EDI were also obtained on the Equator-S satellite, which was launched in December, 1997. A satellite failure caused a loss of the Equator-S mission after only 5 months, but these operations were extremely valuable in learning about the characteristics and operations of the complex EDI instrument. The Cluster mission, satellites, and instruments underwent an extensive on-orbit commissioning phase in the Fall of 2000, carrying over through January 2001. During this period all elements of the instruments were checked and careful measurements of inter-experiments interferences were made. EDI is currently working exceptionally well in orbit. Initial results verify that all aspects of the instrument are working as planned, and returning highly valuable scientific information. The first two papers describing EDI on-orbit results have been submitted for publication in April, 2001. The principles of the EDI technique, and its implementation on Cluster are described in two papers by Paschmann et al., attached as Appendices A and B.

    1981-01-01

    New developments in electronics and radiation detectors are improving on real-time data acquisition of radiation exposure and contamination conditions. Recent developments in low power circuit designs, hybrid and integrated circuits, and microcomputers have all contributed to smaller and lighter radiation detection instruments that are, at the same time, more sensitive and provide more information (e.g., radioisotope identification) than previous devices. New developments in radiation detectors, such as cadmium telluride, gas scintillation proportional counters, and imaging counters (both charged particle and photon) promise higher sensitivities and expanded uses over present instruments. These developments are being applied in such areas as health physics, waste management, environmental monitoring, in vivo measurements, and nuclear safeguards

    This article presents a review of the literature and an evaluation on the development and application of skull-image superimposition technology - both instrumentation and methodology - contributed by a number of scholars since 1935. Along with a comparison of the methodologies involved in the two superimposition techniques - photographic and video - the author characterized the techniques in action and the recent advances in computer image superimposition processing technology. The major disadvantage of conventional approaches is its relying on subjective interpretation. Through painstaking comparison and analysis, computer image processing technology can make more conclusive identifications by direct testing and evaluating the various programmed indices.

    Purified water is one of the most commonly utilized reagents in the laboratory. It is used throughout experimental protocols in virtually every type of laboratory application : as blanks, for the dissolution and dilution of samples, the dilution of standards, preparation of mobile phases and for media and buffer preparation. Contaminants present in purified water can therefore have a significant impact on results. Hence, it is important to ensure that the laboratory water-purification system contains a combination of purification technologies to target specific impurities related to each application. This article looks at some of these technologies and their relevance for specific applications, such as HPLC, LC/MS, and ion chromatography (IC). (author)

    Integrating medical instruments with medical information systems becomes more and more important in healthcare industry. To make medical instruments without standard communication interface possess the capability of interoperating and sharing information with medical information systems, we developed a medical instrument integration gateway based on Integrating the Healthcare Enterprise Patient Care Device (IHE PCD) integration profiles in this research. The core component is an integration engine which is implemented according to integration profiles and Health Level Seven (HL7) messages defined in IHE PCD. Working with instrument specific Javascripts, the engine transforms medical instrument data into HL7 ORU message. This research enables medical instruments to interoperate and exchange medical data with information systems in a standardized way, and is valuable for medical instrument integration, especially for traditional instruments.

    With the evolutionary change in the production activities of human societies, the concept of development has also been changing. In the recent years the emphasis has been on the environmentally sound and sustainable development. The environmentally sound and sustainable development can be obtained through judicious use of technology. Technology as a resource transformer has emerged as the most important factor which can constitute to economic growth. But technology is not an independent and autonomous force, it is only an instrument which needs to be used carefully, properly and appropriately which necessitates technology management. (author)

    In response to recommendations from the Advisory Committee on Reactor Safeguards, the Division of Operational Safety, U.S. ERDA has contracted with Battelle, Pacific Northwest Laboratories to survey the adequacy of existing instrumentation at nuclear fuel cycle facilities to meet emergency requirements and to develop technical criteria for instrumentation systems to be used in assessment of environmental conditions following plant emergencies. This report, the fifth in a series, provides: (1) calibration methods to assure the quality of radiological measurements and (2) testing procedures for determining whether an emergency radiological instrument meets the performance specifications. Three previous reports in this series identified the emergency instrumentation needs for power reactors, mixed oxide fuel plants, and fuel reprocessing facilities. Each of these three reports contains a Section VI, which sets forth applicable radiological instrument performance criteria and calibration requirements. Testing and calibration procedures in this report have been formatted in two parts: IV and V, each divided into three subsections: (1) Power Reactors, (2) Mixed Oxide Fuel Plants, and (3) Fuel Reprocessing Facilities. The three performance criteria subsections directly coincide with the performance criteria sections of the previous reports. These performance criteria sections have been reproduced in this report as Part III with references of ''required action'' added

    The Marine and Hydrokinetic Technology (MHK) Instrumentation, Measurement, and Computer Modeling Workshop was hosted by the National Renewable Energy Laboratory (NREL) in Broomfield, Colorado, July 9-10, 2012. The workshop brought together over 60 experts in marine energy technologies to disseminate technical information to the marine energy community and collect information to help identify ways in which the development of a commercially viable marine energy industry can be accelerated. The workshop was comprised of plenary sessions that reviewed the state of the marine energy industry and technical sessions that covered specific topics of relevance. Each session consisted of presentations, followed by facilitated discussions. During the facilitated discussions, the session chairs posed several prepared questions to the presenters and audience to encourage communication and the exchange of ideas between technical experts. Following the workshop, attendees were asked to provide written feedback on their takeaways and their best ideas on how to accelerate the pace of marine energy technology development. The first four sections of this document give a general overview of the workshop format, provide presentation abstracts and discussion session notes, and list responses to the post-workshop questions. The final section presents key findings and conclusions from the workshop that suggest how the U.S. Department of Energy and national laboratory resources can be utilized to most effectively assist the marine energy industry.

  8. Policy instruments for development of wind power in Sweden; Styrmedel foer vindkraftens utveckling i Sverige

    2003-07-01

    It is often believed that energy policy and policy instruments can play a significant role in the transition towards sustainable energy by stimulating and accelerating the development and deployment of new energy technologies. However, despite the known need for, and benefits of, new energy technologies their market introduction and expansion is often slow. Wind power has been on the political agenda since the 1970s in several European countries as well as in other countries throughout the world. However, the technology and market development of wind power has been very different in these countries. Despite three decades of policy intervention the installed capacity in Sweden was only 265 MW in 2000, compared with 6,107 MW in Germany, 2,836 MW in Spain and 2,341 MW in Denmark. This report analyses the effects of policy instruments on wind power development in Sweden and identifies possible reasons why wind power has not been installed to a greater extent. The analysis is based on an empirical example of a socio technological system-based approach to evaluation of technology and market development for new energy technologies; i.e. an approach focused on the technological system including the actors, institutions and organizations that build, drive and utilise it and the economic and legal framework that regulates it. The aim is to assess the impact on technology and market development and to discuss the relatively late and slow wind power development in Sweden. The report also examines the achievement of governmental energy policy goals. Using the socio-technological systems approach we analyse Swedish policy programmes and wind power development between 1975 and 2000. The political and economic framework is identified. The discussion of the political and economic frameworks is limited to public policy goals and policy instruments. The policy focus is set to policy instruments aimed for technology and market development of wind power, such as research and

    Using various neutron scattering, imaging, and activation analysis instruments and irradiation facility and capsules, the short-term industrial application and mid and long-term basic science with neutrons was carried out. In this regard, we proposed the utilization of the neutron scattering and diffraction techniques to the study of physical, mechanical material properties in industrial components. The nano magnetic thin film structure study using neutron reflectometry, spin structure and dynamics study using neutron scattering, hydrogen combination structure study using single crystal diffraction were carried out. The triple-axis spectrometer has been installed. Also, a new growth facility of single crystal has been developed to supply crystals for the neutron scattering experiment. We have contributed to the performance enhancement of hydrogen fuel cell by the development of quantitative neutron radiography technology and developed the differential phase imaging technology using silicon grating. To perform precise neutron activation analysis, a Compton suppressed gamma-ray spectroscopy system was installed. Through the analysis of actual samples as well as geological and biological reference materials, performance test was carried out. We built up analytical data base and develope integrated analytical program for INAA/PGAA.

    The purpose of this study is to develop the radioisotope tracer technology, which can be used in solving industrial and environmental problems and to build a strong tracer group to support the local industries. In relation to the tracer technology in 1999, experiments to estimate the efficiencies of a sludge digester of a waste water treatment plant and a submerged biological reactor of a dye industry were conducted. As a result, the tracer technology for optimization of facilities related to wastewater treatment has been developed and is believed to contribute to improve their operation efficiency. The quantification of the experimental result was attempted to improve the confidence of tracer technology by ECRIN program which basically uses the MCNP simulation principle. Using thin layer activation technique, wear of tappet shim was estimated. Thin layer surface of a tappet shim was irradiated by proton beam and the correlation between the measured activity loss and the amount of wear was established. The equipment was developed to adjust the energy of proton which collides with the surface of tappet. The tracer project team has participated into the tracer test for estimating the efficiency of RFCC system in SK cooperation. From the experiment the tracer team has obtained the primary elements to be considered for judging the efficiency of RFCC unit. By developing the tracer techniques to test huge industrial units like RFCC, the tracer team will be able to support the local industries that require technical services to solve any urgent trouble.

    By letter dated 27 April 2011, the Director General of the Centre for Strategic Analysis, Vincent Chriqui, confided to Jean Bergougnoux, honorary president of the SNCF, Honorary General Director of EDF, the task of animating a reflection Prospective Technological Studies of the sectors of energy, transport and construction. This synthesis report, prepared with the assistance of rapporteurs Centre for Strategic Analysis, attempts to summarize and put into perspective all the work which show these specific reports. Admittedly some very complex issues still need supplements. It may therefore be useful to extend this work in a number of areas. Beyond its role in the competitiveness of a country, technological innovation is essential to provide appropriate responses to the challenges of our commitment to sustainable development in terms of economic growth, preservation of the environmental and social progress. Mission for Prospective Technological conducted by the Centre for Strategic Analysis has sought to clarify this dual problem by proposing a long-term vision for the energy, transport and construction. For each technology studied, it has attempted to assess both the possible contribution to sustainable development and the competitive potential of our country on the international scene. His work, chaired by Jean Bergougnoux have reviewed the technological advances that may occur in the coming decades in the sectors concerned. They examined the conditions for integration of these advances in systems and subsystems existing (or create) and the conditions of a mature technical, economic but also social. Wherever possible, two time horizons were identified: a medium-term horizon, 2030, for which we have a fairly clear vision of future developments and long-term horizon, 2050, which allows to consider jumps Scientists are still uncertain. Finally, the mission is interested in four transverse technologies involved consistently in the three study areas, which are likely to

    The W. M. Keck Observatory continues to develop new capabilities in support of our science driven strategic plan which emphasizes leadership in key areas of observational astronomy. This leadership is a key component of the scientific productivity of our observing community and depends on our ability to develop new instrumentation, upgrades to existing instrumentation, and upgrades to supporting infrastructure at the observatory. In this paper we describe the as measured performance of projects completed in 2014 and the expected performance of projects currently in the development or construction phases. Projects reaching completion in 2014 include a near-IR tip/tilt sensor for the Keck I adaptive optics system, a new center launch system for the Keck II laser guide star facility, and NIRES, a near-IR Echelle spectrograph for the Keck II telescope. Projects in development include a new seeing limited integral field spectrograph for the visible wavelength range called the Keck Cosmic Web Imager, a deployable tertiary mirror for the Keck I telescope, upgrades to the spectrograph detector and the imager of the OSIRIS instrument, and an upgrade to the telescope control systems on both Keck telescopes.

  15. Development of an international standard on instruments setpoints based on ISA S67.04 - 1994

    International Nuclear Information System (INIS)

    Quinn, E.L.

    1996-01-01

    This is a summary of the application for and development of an international standard on instrument setpoints, based on the Instrument Society of America (ISA) Standard S67.04 - 1994. The forum this new standard was proposed in is the International Electrotechnique Commission (IEC), based in Geneva, Switzerland, which is the international commission which oversees electrical and instrumentation standards for all applications around the world. The Instrument Society of America (ISA) is a United States based Society for the advancement of instrumentation and controls related science and technology and has 30,000 members. A division within the ISA is the Standard and Practices board which has over 5000 members actively involved in standards development and approval. In 1994, the ISA SP67, Nuclear Power Plant Standards Committee authorized that the IEC be approached to develop and issue an IEC standard on Instrument Setpoints. This application was formally submitted in January, 1995 to the IEC and approved for ballot to member countries in June, 1995. Approval for standard development by IEC was received in October, 1995 and the first draft vas issued in February, 1996, and is currently under review by the IEC working group. It is very important to focus on the approach that the U.S. and other countries are taking toward development of IEC standards that can apply to all nuclear instrumentation applications around the world. By referencing IEC standards in design specification, vendors can be solicited from many different countries, thereby ensuring that the highest quality products can be used. This also offsets the need to specify individual standards in the specification, based on the country that each vendor solicited, represents. In summary, this standard development process, with support from the American National Standards Institute (ANSI) will assist U.S. suppliers in competing in the global market for products and services into the next century.

    The genetic technologies being adopted in South Asia are significant factors in the agricultural development of the area. But, labeling them " miracle seeds," solely responsible for recent agricultural growth, is misleading. Certainly the introduction of new genetic technology has catalyzed South Asian agriculture and has instilled a new dynamism essential to economic development. Somewhat similar phenomena have, however, been observed in other parts of the world in other periods of history. The nature of these genetic technologies, how they are being applied, and their limits and potential have been explored above. Also, the effects of these varieties on the generation of employment, and the distribution of benefits accruing from them have been examined in preliminary fashion. Stemming from the preceding discussion, two areas of priority appear obvious. First, the close association of genetic technologies with irrigation suggests that irrigation should receive more attention than it has in the past. Large-scale public irrigation schemes are expensive and have tended to yield low rates of return. However, there appears to be room for marginal increases in, or improvements of, existing irrigation facilities. Second, even with a rapid spread of the practices associated with highyeild varieties, it may be too much to expect the farm sector to absorb the expected increases in the rural labor force. The generation of employment is a major problem in India as well as in most other developing countries. Hence, possibilities for expanding rural, nonfarm employment and controlling population growth should be sought vigorously.

  3. Human factors survey of advanced instrumentation and controls technologies in nuclear plants

    International Nuclear Information System (INIS)

    Carter, R.J.

    1992-01-01

    A survey of advanced instrumentation and controls (I ampersand C) technologies and associated human factors issues in the US and Canadian nuclear industries was carried out by a team from Oak Ridge national laboratory to provide background for the development of regulatory policy, criteria, and guides for review of advanced I ampersand C systems as well as human engineering guidelines for evaluating these systems. The survey found those components of the US nuclear industry surveyed to be quite interested in advanced I ampersand C, but very cautious in implementing such systems in nuclear facilities and power plants. The trend in the facilities surveyed is to experiment cautiously when there is an intuitive advantage or short-term payoff. In the control room, the usual practice is direct substitution of digital and microprocessor-based instruments or systems that are functionally identical to the analog instruments or systems being replaced. The most advanced I ampersand C systems were found in the Canadian CANDU plants, where the newest plant has digital system in almost 100% of its control systems and in over 70% of its plant protection system. The hypothesis that properly 'introducing digital systems increases safety' is supported by the Canadian experience. The performance of these digital systems was achieved using an appropriate quality assurance program for the software development. The ability of digital systems to detect impending failures and initiate a fail-safe action, is a significant safety issue that should be of special interest to every US utility as well as to the US Nuclear Regulatory Commission.

  4. Novel instrumentation of multispectral imaging technology for detecting tissue abnormity

    2012-10-01

    Multispectral imaging is becoming a powerful tool in a wide range of biological and clinical studies by adding spectral, spatial and temporal dimensions to visualize tissue abnormity and the underlying biological processes. A conventional spectral imaging system includes two physically separated major components: a band-passing selection device (such as liquid crystal tunable filter and diffraction grating) and a scientific-grade monochromatic camera, and is expensive and bulky. Recently micro-arrayed narrow-band optical mosaic filter was invented and successfully fabricated to reduce the size and cost of multispectral imaging devices in order to meet the clinical requirement for medical diagnostic imaging applications. However the challenging issue of how to integrate and place the micro filter mosaic chip to the targeting focal plane, i.e., the imaging sensor, of an off-shelf CMOS/CCD camera is not reported anywhere. This paper presents the methods and results of integrating such a miniaturized filter with off-shelf CMOS imaging sensors to produce handheld real-time multispectral imaging devices for the application of early stage pressure ulcer (ESPU) detection. Unlike conventional multispectral imaging devices which are bulky and expensive, the resulting handheld real-time multispectral ESPU detector can produce multiple images at different center wavelengths with a single shot, therefore eliminates the image registration procedure required by traditional multispectral imaging technologies.

    Full Text Available Małgorzata Farnik, Władysław PierzchałaDepartment of Pneumonology, Silesian University of Medicine, Katowice, PolandAbstract: Patient-related outcomes measures could provide important information for the current state of the art in medical care and even have an impact on macrodecisions in the health care system. Patient-related outcomes were initially defined as subjective health indicators that allow disability and illness to be assessed, based on patient, caregiver, or physician self-reports. As illness involves psychological and behavioral complex processes of care, a multidisciplinary approach in measuring patient-reported outcomes should be recommended, such as quality of life questionnaires. Patient-related outcomes measures should correspond to specific clinical situations and bring opportunities to improve quality of care. Objective measurements enable quantitative data to be collected and analyzed. Depending on the aim of the research, investigators can use existing methods or develop new tools. This publication presents a methodology for developing patient-related outcomes measures, based on a multistage procedure. The proper definition of specific study objectives and the methodology of instrument development are crucial for successfully transferring the study concept. The model of instrument development is the process of starting from the preliminary phase and includes questionnaire design and scaling, pilot testing (cognitive debriefing, revision of the preliminary version, evaluation of the new tool, and implementation. Validation of the new instrument includes reliability, reproducibility, internal consistency, and responsiveness. The process of designing the new tool should involve a panel of experts, including clinicians, psychologists (preliminary phase, and statisticians (scale development and scoring, and patients (cognitive debriefing. Implementation of a new tool should be followed by evaluation study – assessment of

    2014-01-01

    Background Utilization indices exist to measure quantity of prenatal care, but currently there is no published instrument to assess quality of prenatal care. The purpose of this study was to develop and test a new instrument, the Quality of Prenatal Care Questionnaire (QPCQ). Methods Data for this instrument development study were collected in five Canadian cities. Items for the QPCQ were generated through interviews with 40 pregnant women and 40 health care providers and a review of prenatal care guidelines, followed by assessment of content validity and rating of importance of items. The preliminary 100-item QPCQ was administered to 422 postpartum women to conduct item reduction using exploratory factor analysis. The final 46-item version of the QPCQ was then administered to another 422 postpartum women to establish its construct validity, and internal consistency and test-retest reliability. Results Exploratory factor analysis reduced the QPCQ to 46 items, factored into 6 subscales, which subsequently were validated by confirmatory factor analysis. Construct validity was also demonstrated using a hypothesis testing approach; there was a significant positive association between women’s ratings of the quality of prenatal care and their satisfaction with care (r = 0.81). Convergent validity was demonstrated by a significant positive correlation (r = 0.63) between the “Support and Respect” subscale of the QPCQ and the “Respectfulness/Emotional Support” subscale of the Prenatal Interpersonal Processes of Care instrument. The overall QPCQ had acceptable internal consistency reliability (Cronbach’s alpha = 0.96), as did each of the subscales. The test-retest reliability result (Intra-class correlation coefficient = 0.88) indicated stability of the instrument on repeat administration approximately one week later. Temporal stability testing confirmed that women’s ratings of their quality of prenatal care did not change as a result of giving

    The Sentinel-5 instrument is currently under development by a consortium led by Airbus Defence and Space in the frame of the European Union Copernicus program. It is a customer furnished item to the MetOp Second Generation satellite platform, which will provide operational meteorological data for the coming decades. Mission objective of the Sentinel-5 is to monitor the composition of the Earth atmosphere for Copernicus Atmosphere Services by taking measurements of trace gases and aerosols impacting air quality and climate with high resolution and daily global coverage. Therefore the Sentinel-5 provides five dispersive spectrometers covering the UV-VIS (270…500 nm), NIR (685 …773 nm) and SWIR (1590…1675 and 2305…2385 nm) spectral bands with resolutions <=1nm. Spatially the Sentinel-5 provides a 108° field of view with a ground sampling of 7.5 x 7 km2 at Nadir. The development program is post PDR and the build-up of the industrial team is finalised. We report on the instrument architecture and design derived from the driving requirements, the predicted instrument performance, and the general status of the program.

    Nuclear power plant (NPP) is a multi-input and multi-output, no-linear and time-varying complex system. The conventional PID controller is usually used in NPP control system which is based on analog instrument. The system parameters are easy to overshoot and the response time is longer in the control mode of the conventional PID. In order to improve this condition, a new coordinated control strategy which is based on expert system and the original controllers in the digital instrument and control technology was presented. In order to verify and validate it, the proposed coordinated control technology was tested by the full-scope real-time simulation system. The results prove that using digital instrument and control technology to achieve coordinated controller is feasible, the coordinated controller can effectively improve the dynamic operating characteristics of the system, and the coordinated controller is superior to the conventional PID controller in control performance.

    The neutron scattering program at the Los Alamos spallation neutron source is based on the operational WNR facility which provides up to 11 μA of 800 MeV protons to a target in pulse widths up to 8 μs at 120 Hz. The immediate goals of the program are: to gain experience with neutron instrumentation at spallation neutron sources; and to explore the scientific potential for condensed matter research at these sources. The proton storage ring (PSR) funded for construction will provide 100 μA in 0.27 μs pulses at 12 Hz, therefore greatly improving intensity, time-of-flight (TOF) resolution, and repetition rate. The initial emphasis, given limited manpower and resources, has been placed on developing a set of prototype instruments which are relatively easy to implement and which take advantage of the unique characteristics of the present WNR when compared with reactor neutron sources

    Energy efficiency is the critical parameter for policies that aim at reducing energy consumption while maintaining or even boosting economic growth. The two main options to influence energy efficiency are changes in relative prices, i.e., raising the price of energy through economic instruments, or to introduce new technologies which increase the productivity of each unit of energy. This paper is based on the notion that in an equilibrium economy the marginal economic productivity is identical for all factors, i.e., energy, labour, knowledge and capital. From this premise two main conclusions can be drawn. First, any change in price or technology will have an impact on the whole economy by creating feedbacks through the substitution of factors of production and goods, as well as increased wealth. Second, the two policy approaches, changing relative prices and technology development, are not opposite to each other. They are the two faces of the same reality and should be developed and promoted simultaneous and consistently. (Author)

    This article reports on the implications and benefits of Internet technology among women from developing countries. Cyberfeminism is the practice of feminism in cyberspace. Feminists believe that women should take control and augment Internet technologies to empower themselves. Learning to use the computers, getting "connected," and surfing the Internet are encouraged among all women with the aim of advancing feminist causes and empowering women. The Internet has been observed to cause radical changes in the way business and social activities are conducted. A description of how two women have engaged in cyberfeminism and worked in development and technology programs is included. One contributor, Annapurna Mamipudi, is involved in a non-governmental organization working with traditional handloom weavers in India Another contributor is Radhika Gajjala, who works in academia and creates on-line "discussion lists" and Web sites from her North American geographical location. Her job is to create spaces that provide opportunities for dialogue and collaboration among women with Internet access all over the world.

    Technology procurement is used as an environmental control means in Sweden to promote the manufacturing and sale of energy-efficient technologies. The public authority in charge makes use of the market mechanism in alternating co-operative and competitive elements. The fragmented market, with its standardised products for many small customers, is brought together to specify desired product developments. These demands also include other qualities besides energy efficiency. A contest is announced in which a possible future market is indicated to manufacturers. Efforts are made to enlarge the market to motivate their investment and to keep down the unit cost. Each side in the deal is thus given an incentive to act in the desired direction. (author)

The extent of routine operational releases has been reviewed for the light water reactor (LWR) fuel cycle (including plutonium recycle), the breeder reactor fuel cycle, and the high-temperature gas cooled reactor (HTGR) fuel cycle. The stack monitoring instrumentation that is presently in use at the various fabrication and reprocessing plants around the country is examined. Sampling difficulties including the inlet-probe arrangement and the effectiveness of the entire sampling system are discussed, as are the measurement problems for alpha-emitting, long-lived, transuranic aerosols, 129 I, 106 Ru, and tritium oxide. The potential problems in the HTGR fuel cycle such as the measurement of releases of alpha-emitting aerosols and of gaseous releases of 220 Rn and 14 C are also considered. Monitoring requirements range from the detection of low-level, routine releases to high-level accidental releases. Both first and second kinds of detection errors are considered in a discussion of adequate detection limits. The presently deployed monitors are critically examined in this light and the drawbacks and limitations of each are noted. Prototype instrumentation is studied, including Argonne's mechanical separation technique, Battelle's mass separation by surface ionization method, and in particular, LLL's transuranic aerosol measurement system. The potentials, sensitivities, advantages, and limitations of each system are enumerated. The additional potential uses of the LLL system are also discussed

    Considerable effort in the astronomy education research (AER) community over the past several years has focused on developing assessment tools in the form of multiple-choice conceptual diagnostics and content knowledge surveys. This has been critically important in advancing the AER discipline so that researchers could establish the initial knowledge state of students as well as to attempt measure some of the impacts of innovative instructional interventions. Unfortunately, few of the existing instruments were constructed upon a solid list of clearly articulated and widely agreed upon learning objectives. This was not done in oversight, but rather as a result of the relative youth of AER as a discipline. Now that several important science education reform documents exist and are generally accepted by the AER community, we are in a position to develop, validate, and disseminate a new assessment instrument which is tightly aligned to the consensus learning goals stated by the American Astronomical Society - Chair's Conference on ASTRO 101, the American Association of the Advancement of Science's Project 2061 Benchmarks, and the National Research Council's National Science Education Standards. In response, researchers from the Cognition in Astronomy, Physics and Earth sciences Research (CAPER) Team at the University of Wyoming's Science & Math Teaching Center (UWYO SMTC) have designed a criterion-referenced assessment tool, called the Test Of Astronomy STandards (TOAST). Through iterative development, this instrument has a high degree of reliability and validity for instructors and researchers needing information on students’ initial knowledge state at the beginning of a course and can be used, in aggregate, to help measure the impact of course-length duration instructional strategies for courses with learning goals tightly aligned to the consensus goals of our community.

    Nuclear power plant (NPP) with VPBER-600 reactor is a station of new generation. The specified term of reactor plant operation is 60 years and taking into account that the proposed term of starting the first power unit is on the turn of centuries one can definitely state that for Russia conditions VPBER-600 is a plant of 21 century. Such far removed term for NPP now in the stage of development as it can seem does not put the problems of modernization as first order tasks. But open-quotes...who does not think about future lives in the past.close quotes It is that the NPP instrumentation and control (I ampersand C) systems are in the most degree subjected to the influence of factors which favor their modifications. These factors can be arbitrarily divided into two groups: (1) inner factors, i.e. changes (failures, aging, etc) in I ampersand C components as well as changes dictated by technological reasons (change of equipment composition, control algorithms, operation modes); (2) outer factors, i.e. intensive development of information technologies and rapid improvement of electronic components. This presentation addresses the problem of modernization of the safety instrumentation for this next generation facility, and the research effort it will entail. The system is designed to allow for modernization, and the relatively easy adoption of new instrumentation and technology as it becomes available

    New and enhanced nuclear fuels are a key enabler for new and improved reactor technologies. For example, the goals of the next generation nuclear plant (NGNP) will not be met without irradiations successfully demonstrating the safety and reliability of new fuels. Likewise, fuel reliability has become paramount in ensuring the competitiveness of nuclear power plants. Recently, the Office of Nuclear Energy in the Department of Energy (DOE-NE) launched a new direction in fuel research and development that emphasizes an approach relying on first principle models to develop optimized fuel designs that offer significant improvements over current fuels. To facilitate this approach, high fidelity, real-time, data are essential for characterizing the performance of new fuels during irradiation testing. A three-year strategic research program is proposed for developing the required test vehicles with sensors of unprecedented accuracy and resolution for obtaining the data needed to characterize three-dimensional changes in fuel microstructure during irradiation testing. When implemented, this strategy will yield test capsule designs that are instrumented with new sensor technologies for the Advanced Test Reactor (ATR) and other irradiation locations for the Fuel Cycle Research and Development (FC R&D) program. Prior laboratory testing, and as needed, irradiation testing, of these sensors will have been completed to give sufficient confidence that the irradiation tests will yield the required data. Obtaining these sensors must draw upon the expertise of a wide-range of organizations not currently supporting nuclear fuels research. This document defines this strategic program and provides the necessary background information related to fuel irradiation testing, desired parameters for detection, and an overview of currently available in-pile instrumentation. In addition, candidate sensor technologies are identified in this document, and a list of proposed criteria for ranking

    The objectives of this study are to develop the technology for the determination of isotopic ratios of nuclear particles detected from swipe samples and to develop the NIPS system. The R and D contents and results of this study are firstly the production of nuclear micro particle(1 ∼ 20 μm) and standardization, the examination of variation in fission track characteristic according to nuclear particle size and enrichment( 235 U: 1-50%), the construction of database and the application of this technique to swipe samples. If this technique is verified its superiority by various field tests and inter-laboratory comparison program with other institutes in developed countries, it can be possible to join NWAL supervised under IAEA and to export our technology abroad. Secondly, characteristics of alpha track by boron (n, α) nuclear reaction were studied to measure both total boron concentration and 10B enrichment. The correlation of number of alpha tracks and various 10B concentration was studied to evaluate the reliability of this method. Especially, cadmium shielding technique was introduced to reduce the background of alpha tracks by covering the solid track detector and the multi-dot detector plate was developed to increase the reproducibility of measurement by making boron solution dried evenly in the plate. The results of the alpha track method were found to be well agreed with those of mass spectroscopy within less than 10 % deviation. Finally, the NIPS system using 252 Cf neutron source was developed and prompt gamma spectrum and its background were obtained. Monte Carlo method using MCNP-4B code was utilized for the interpretation of neutron and gamma-ray shielding condition as well as the moderation of a fast neutron. Gamma-gamma coincidence was introduced to reduce the prompt gamma background. The counting efficiency of the HPGe detector was calibrated in the energy range from 50 keV to 10 MeV using radio isotope standards and prompt gamma rays of Cl for the

    The European Spallation Source (ESS), scheduled to start operation in 2020, is aiming to deliver the most intense neutron beams for experimental research of any facility worldwide. Its long pulse time structure implies significant differences for instrumentation compared to other spallation sources which, in contrast, are all providing short neutron pulses. In order to enable the development of methods and technology adapted to this novel type of source well in advance of the first instruments being constructed at ESS, a test beamline (TBL) was designed and built at the BER II research reactor at Helmholtz-Zentrum Berlin (HZB). Operating the TBL shall provide valuable experience in order to allow for a smooth start of operations at ESS. The beamline is capable of mimicking the ESS pulse structure by a double chopper system and provides variable wavelength resolution as low as 0.5% over a wide wavelength band between 1.6 Å and 10 Å by a dedicated wavelength frame multiplication (WFM) chopper system. WFM is proposed for several ESS instruments to allow for flexible time-of-flight resolution. Hence, ESS will benefit from the TBL which offers unique possibilities for testing methods and components. This article describes the main capabilities of the instrument, its performance as experimentally verified during the commissioning, and its relevance to currently starting ESS instrumentation projects.

    Although nursing students spend a large part of their learning period in the clinical environment, clinical learning has not been perceived by its nature yet. To develop an instrument to measure effective factors on clinical learning in nursing students. This is a mixed methods study performed in 2 steps. First, the researchers defined "clinical learning" in nursing students through qualitative content analysis and designed items of the questionnaire based on semi-structured individual interviews with nursing students. Then, as the second step, psychometric properties of the questionnaire were evaluated using the face validity, content validity, construct validity, and internal consistency evaluated on 227 students from fourth or higher semesters. All the interviews were recorded and transcribed, and then, they were analyzed using Max Qualitative Data Analysis and all of qualitative data were analyzed using SPSS 14. To do the study, we constructed the preliminary questionnaire containing 102 expressions. After determination of face and content validities by qualitative and quantitative approaches, the expressions of the questionnaire were reduced to 45. To determine the construct validity, exploratory factor analysis was applied. The results indicated that the maximum variance percentage (40.55%) was defined by the first 3 factors while the rest of the total variance percentage (59.45%) was determined by the other 42 factors. Results of exploratory factor analysis of this questionnaire indicated the presence of 3 instructor-staff, students, and educational related factors. Finally, 41 expressions were kept in 3 factor groups. The α-Cronbach coefficient (0.93) confirmed the high internal consistency of the questionnaire. Results indicated that the prepared questionnaire was an efficient instrument in the study of the effective factors on clinical learning as viewed by nursing students since it involves 41 expressions and properties such as instrument design based

    Although speech perception tests are available to evaluate hearing, there is no standardized validated tool to quantify speech quality. The objective of this study is to develop a validated tool to measure quality of speech heard. Prospective instrument validation study of 35 normal hearing adults recruited at a tertiary referral center. Participants listened to 44 speech clips of male/female voices reciting the Rainbow Passage. Speech clips included original and manipulated excerpts capturing goal qualities such as mechanical and garbled. Listeners rated clips on a 10-point visual analog scale (VAS) of 18 characteristics (e.g. cartoonish, garbled). Skewed distribution analysis identified mean ratings in the upper and lower 2-point limits of the VAS (ratings of 8-10, 0-2, respectively); items with inconsistent responses were eliminated. The test was pruned to a final instrument of nine speech clips that clearly define qualities of interest: speech-like, male/female, cartoonish, echo-y, garbled, tinny, mechanical, rough, breathy, soothing, hoarse, like, pleasant, natural. Mean ratings were highest for original female clips (8.8) and lowest for not-speech manipulation (2.1). Factor analysis identified two subsets of characteristics: internal consistency demonstrated Cronbach's alpha of 0.95 and 0.82 per subset. Test-retest reliability of total scores was high, with an intraclass correlation coefficient of 0.76. The Speech Quality Instrument (SQI) is a concise, valid tool for assessing speech quality as an indicator for hearing performance. SQI may be a valuable outcome measure for cochlear implant recipients who, despite achieving excellent speech perception, often experience poor speech quality. 2b.

    The workshop participants were asked to: (1) Assess the current capabilities of chemical sensor technologies for addressing US Department of Energy (DOE) Environmental Restoration and Waste Management (EM) needs; (2) Estimate potential near term (one to two years) and intermediate term (three to five years) capabilities for addressing those needs; and (3) Generate a ranked list of specific recommendations on what research and development (R&D) should be funded to provide the necessary capabilities. The needs were described in terms of two pervasive EM problems, the in situ determination of chlorinated volatile organic compounds (VOCs), and selected metals in various matrices at DOE sites. The R&D recommendations were to be ranked according to the estimated likelihood that the product technology will be ready for application within the time frame it is needed and the estimated return on investment. The principal conclusions and recommendations of the workshop are as follows: Chemical sensors capable of in situ determinations can significantly reduce analytical costs; Chemical sensors have been developed for certain VOCs in gases and water but none are currently capable of in situ determination of VOCs in soils; The DOE need for in situ determination of metals in soils cannot be addressed with existing chemical sensors and the prospects for their availability in three to five years are uncertain; Adaptation, if necessary, and field application of laboratory analytical instruments and those few chemical sensors that are already in field testing is the best approach for the near term; The chemical sensor technology development plan should include balanced support for near- and intermediate-term efforts.

    The workshop participants were asked to: (1) Assess the current capabilities of chemical sensor technologies for addressing US Department of Energy (DOE) Environmental Restoration and Waste Management (EM) needs; (2) Estimate potential near term (one to two years) and intermediate term (three to five years) capabilities for addressing those needs; and (3) Generate a ranked list of specific recommendations on what research and development (R ampersand D) should be funded to provide the necessary capabilities. The needs were described in terms of two pervasive EM problems, the in situ determination of chlorinated volatile organic compounds (VOCs), and selected metals in various matrices at DOE sites. The R ampersand D recommendations were to be ranked according to the estimated likelihood that the product technology will be ready for application within the time frame it is needed and the estimated return on investment. The principal conclusions and recommendations of the workshop are as follows: Chemical sensors capable of in situ determinations can significantly reduce analytical costs; Chemical sensors have been developed for certain VOCs in gases and water but none are currently capable of in situ determination of VOCs in soils; The DOE need for in situ determination of metals in soils cannot be addressed with existing chemical sensors and the prospects for their availability in three to five years are uncertain; Adaptation, if necessary, and field application of laboratory analytical instruments and those few chemical sensors that are already in field testing is the best approach for the near term; The chemical sensor technology development plan should include balanced support for near- and intermediate-term efforts

    Full Text Available The new EU target of achieving 80-95% emission reductions by 2050 calls for novel energy policy solutions. Previous research has failed to evaluate the influence of all relevant elements of energy policy on technology-specific sustainable renewable energy diffusion. This paper adds to existing research by studying the effectiveness of financial and fiscal instruments on diffusion, additionally controlling for potential political, economic, social, and environmental drivers. These drivers are analysed for 26 EU countries over the period 1990-2011. The main results show that feed-in tariffs, quotas, and tenders effectively promote wind technologies. Other explanatory variables have technology- and model-dependent impacts.

    DUPIC safeguards R and D in the second phase has focused on the development of nuclear material measurement system and its operation and verification, the development of nuclear material control and accounting system, and the development of remote and unmanned containment/surveillance system. Of them, the nuclear material measurement system was authenticated from IAEA and officially used for IAEA and domestic safeguards activities in DFDF. It was also verified that the system could be used for quality control of DUPIC process. It is recognised that the diagnostic software using neural network and remote and unmanned containment/surveillance system developed here could be key technologies to go into remote and near-real time monitoring system. The result of this project will eventually contribute to similar nuclear fuel cycles like MOX and pyroprocessing facility as well as the effective implementation of DUPIC safeguards. In addition, it will be helpful to enhance international confidence build-up in the peaceful use of spent fuel material

    The base floor of SANS was constructed by the 27 steel plates with horizontal flatness of {+-}0.5mm. That is for the two dimensional position sensitivity neutron detector(2D-PSD), which is operated in vacuum chamber, as moving smoothly. Concerned to the equipments, we designed and installed the inner-shielding of the PNS which will be used for research of magnetic structure and critical phenomena of the materials. In the development of experimental devices, we have designed and manufactured a beam-stop exchange unit and a detector carriage which are used for 2D-PSD. The detector carriage is to control the distance between sample and detector. The beam-stop exchange unit is to protect detector from exposure of direct neutron beam. Especially, many experimental devices or instruments such as high-resolution collimator, components for low temperature facility, multi-purpose vacuum chamber, etc. were made in domestic, it is worth meaningful in domestic availability and standardization for the neutron instrument component.

    Full Text Available An examination of the psychometric properties of the Lateral Violence in Nursing Survey (LVNS, an instrument previously developed to measure the perceived incidence and severity of lateral violence (LV in the nursing workplace, was carried out. Conceptual clustering and principal components analysis were used with survey responses from 663 registered nurses and ancillary nursing staff in a southeastern tertiary care medical center. Where appropriate, Cronbach’s alpha (α evaluated internal consistency. The prevalence/severity of lateral violence items constitute two distinct subscales (LV by self and others with Cronbach’s alpha of 0.74 and 0.86, respectively. The items asking about potential causes of LV are unidimensional and internally consistent (alpha = 0.77 but there is no conceptually coherent theme underlying the various causes. Respondents rating a potential LV cause as “major” scored higher on both prevalence/severity subscales than those rating it a “minor” cause or not a cause. Subsets of items on the LVNS are internally reliable, supporting construct validity. Revisions of the original LVNS instrument will improve its use in future work.

    2009-03-01

    In the next few years political decisions lie ahead in Sweden and the EU regarding the detailed formulation of the EU's so-called 20-20-20 targets and accompanying EU directives. Talks on a new international post-2012 climate agreement are imminent. The EU targets involve reducing emissions of greenhouse gases by 20 per cent, increasing the proportion of renewable energy by 20 per cent and improving energy efficiency by 20 per cent - all by the year 2020. According to the analysis of the consequences of the targets that the Technology Development Group has commissioned, the reduction in carbon dioxide in the stationary energy system in the Nordic region will be 40 per cent, not 20 per cent, if all the EU targets are to be achieved. The biggest socio-economic cost is associated with achieving the efficiency target, followed by the costs associated with achieving the renewable energy target and the CO 2 target. On the basis of this analysis and compilations about technology development, we want to highlight the following important key issues: Does Sweden want to have the option of nuclear power in the future or not? How to choose good policy instruments for new electricity production and networks? How best to reduce the carbon dioxide emissions of the transport sector and how to develop control and incentive measures that promote such a development? We are proposing the following: Carry out a more in-depth analysis of the consequences of the EU targets, so that the policy instruments produce the best combination as regards climate, economy and security of supply. To achieve the EU targets would require large investments in electricity production, particularly renewable energy, and in electricity networks. Internationally harmonized policy instruments and other incentive measures are required in order for the necessary investments to take place. The policy instruments have to provide a level playing field for all players in the energy sector. The large investments

    IT-related self-efficacy has been found to have a critical influence on system use. However, traditional measures of computer self-efficacy and Internet-related self-efficacy are perceived to be inapplicable in the context of mobile computing and commerce because they are targeted primarily at either desktop computer or wire-based technology contexts. Based on previous research, this study develops and validates a multidimensional instrument for measuring mobile computing self-efficacy (MCSE). This empirically validated instrument will be useful to researchers in developing and testing the theories of mobile user behavior, and to practitioners in assessing the mobile computing self-efficacy of users and promoting the use of mobile commerce systems.

  19. Development and validation of a trustworthy multisource feedback instrument to support nurse appraisals.

    Nurse appraisal is well established in the Western world because of its obvious educational advantages. Appraisal works best with many sources of information on performance. Multisource feedback (MSF) is widely used in business and in other clinical disciplines to provide such information. It has also been incorporated into nursing appraisals, but, so far, none of the instruments in use for nurses has been validated. We set out to develop an instrument aligned with the UK Knowledge and Skills Framework (KSF) and to evaluate its reliability and feasibility across a wide hospital-based nursing population. The KSF framework provided a content template. Focus groups developed an instrument based on consensus. The instrument was administered to all the nursing staff in 2 large NHS hospitals forming a single trust in London, England. We used generalizability analysis to estimate reliability, response rates and unstructured interviews to evaluate feasibility, and factor structure and correlation studies to evaluate validity. On a voluntary basis the response rate was moderate (60%). A failure to engage with information technology and employment-related concerns were commonly cited as reasons for not responding. In this population, 11 responses provided a profile with sufficient reliability to inform appraisal (G = 0.7). Performance on the instrument was closely and significantly correlated with performance on a KSF questionnaire. This is the first contemporary psychometric evaluation of an MSF instrument for nurses. MSF appears to be as valid and reliable as an assessment method to inform appraisal in nurses as it is in other health professional groups. © 2015 The Alliance for Continuing Education in the Health Professions, the Society for Academic Continuing Medical Education, and the Council on Continuing Medical Education, Association for Hospital Medical Education.

    Scientific ground-truth measurements for near-term Mars missions, such as the 2009 Mars Science Laboratory (MSL) mission, are essential for validating current in situ flight instrumentation and for the development of advanced instrumentation technologies for life-detection missions over the next decade. The NASA Astrobiology Institute (NAI) has recently funded a consortium of researchers called the Astrobiology Sample Analysis Program (ASAP) to analyze an identical set of homogenized martian analog materials in a "round-robin" style using both state-of-the-art laboratory techniques as well as in-situ flight instrumentation including the SAM gas chromatograph mass spectrometer and CHEMIN X-ray diffraction/fluorescence instruments on MSL and the Urey and MOMA organic analyzer instruments under development for the 2013 ExoMars missions. The analog samples studied included an Atacama Desert soil from Chile, the Murchison meteorite, a gypsum sample from the 2007 AMASE Mars analog site, jarosite from Panoche Valley, CA, a hydrothermal sample from Rio Tinto, Spain, and a "blind" sample collected during the 2007 MSL slow-motion field test in New Mexico. Each sample was distributed to the team for analysis to: (1) determine the nature and inventory of organic compounds, (2) measure the bulk carbon and nitrogen isotopic composition, (3) investigate elemental abundances, mineralogy and matrix, and (4) search for biological activity. The experimental results obtained from the ASAP Mars analog research consortium will be used to build a framework for understanding the biogeochemistry of martian analogs, help calibrate current spaceflight instrumentation, and enhance the scientific return from upcoming missions.

    In recent years the promotion of marine observations based on volunteer participation, known as Citizen Science, has provided environmental data with unprecedented resolution and coverage. The Citizen Science based approach has the additional advantage to engage people by raising awareness and knowledge of marine environmental problems. The technological advances in embedded systems and sensors, enables citizens to create their own devices (known as DIY, Do-It-Yourself, technologies) for monitoring the marine environment. Within the context of the CITCLOPS project (www.citclops.eu), a DIY instrument was developed to monitor changes on water transparency as a water quality indicator. The instrument, named KdUINO, is based on quasi-digital sensors controlled by an open-hardware (Arduino) board. The sensors measure light irradiance at different depth and the instrument automatically calculates the light diffuse attenuation Kd coefficient to quantify the water transparency. The buoy construction is an ideal activity for creative STEM programming. Several workshops in high schools were done to show to the students how to construct their own buoy. Some of them used the buoy to develop their own scientific experiments. In order to engage students more motivated in artistic disciplines, the research group developed also a sonification system that allows creating music and graphics using KdUINO measurements as input data.

    The design and construction of an instrumented and active robotic gripper is presented in this paper. The gripping device is a four-bar-linkage parallel jaw type end effector and the fingers are actuated by DC servo motor and gear drive. To make the gripper active, it is equipped with several sensors viz. straingauge type force sensor, magnetic proximity sensor, infrared sensor and vision sensor. A potentiometric position sensor is used to give position feed back of the fingers to the gripper controller. All sensory data are received by a Z-80 microprocessor and a software is developed to process data to transmit corresponding signals to the servocontroller designed for the gripper activation. The gripper can be used for automated grasping of randomly scattered object that remains in the field of view of the camera mounted on the gripper. (author). 3 refs., 2 figs

    Full Text Available The WHOQOL instrument was adapted as a health-related QOL instrument for a population-based epidemiologic study of eye diseases in southern India, the Andhra Pradesh Eye Disease Study (APEDS. A follow-up question was added to each item in WHOQOL to determine whether the decrease in QOL was due to any health reasons including eye-related reasons. Modifications in WHOQOL and translation in local language were done through the use of the focus groups including health professionals and people not related to health care. The modified instrument has 28 items across 6 domains of the WHOQOL and was translated into the local language, Telugu, using the pragmatic approach. It takes 10-20 minutes to be administered by a trained interviewer. Reliability was within acceptable range. This health-related QOL instrument is being used in the population-based study APEDS to develop a vision-specific QOL instrument which could potentially be used to assess the impact of visual impairment on QOL across different cultures and for use in evaluating eye-care interventions. This health-related QOL instrument could also be used to develop other disease-specific instruments as it allows assessment of the extent to which various aspects of QOL are affected by a variety of health problems.

    This report presents the preliminary results of a research and development project on the validation of new techniques for on-line testing of calibration drift of process instrumentation channels in nuclear power plants. These techniques generally involve a computer-based data acquisition and data analysis system to trend the output of a large number of instrument channels and identify the channels that have drifted out of tolerance. This helps limit the calibration effort to those channels which need the calibration, as opposed to the current nuclear industry practice of calibrating essentially all the safety-related instrument channels at every refueling outage

    The Arctic Energy Technology Development Laboratory was created by the University of Alaska Fairbanks in response to a congressionally mandated funding opportunity through the U.S. Department of Energy (DOE), specifically to encourage research partnerships between the university, the Alaskan energy industry, and the DOE. The enabling legislation permitted research in a broad variety of topics particularly of interest to Alaska, including providing more efficient and economical electrical power generation in rural villages, as well as research in coal, oil, and gas. The contract was managed as a cooperative research agreement, with active project monitoring and management from the DOE. In the eight years of this partnership, approximately 30 projects were funded and completed. These projects, which were selected using an industry panel of Alaskan energy industry engineers and managers, cover a wide range of topics, such as diesel engine efficiency, fuel cells, coal combustion, methane gas hydrates, heavy oil recovery, and water issues associated with ice road construction in the oil fields of the North Slope. Each project was managed as a separate DOE contract, and the final technical report for each completed project is included with this final report. The intent of this process was to address the energy research needs of Alaska and to develop research capability at the university. As such, the intent from the beginning of this process was to encourage development of partnerships and skills that would permit a transition to direct competitive funding opportunities managed from funding sources. This project has succeeded at both the individual project level and at the institutional development level, as many of the researchers at the university are currently submitting proposals to funding agencies, with some success.

    The growing number of cores provided by today’s high-­end computing systems present substantial challenges to application developers in their pursuit of parallel efficiency. To find the most effective optimization strategy, application developers need insight into the runtime behavior of their code. The University of Oregon (UO) and the Juelich Supercomputing Centre of Forschungszentrum Juelich (FZJ) develop the performance analysis tools TAU and Scalasca, respectively, which allow high-­performance computing (HPC) users to collect and analyze relevant performance data – even at very large scales. TAU and Scalasca are considered among the most advanced parallel performance systems available, and are used extensively across HPC centers in the U.S., Germany, and around the world. The TAU and Scalasca groups share a heritage of parallel performance tool research and partnership throughout the past fifteen years. Indeed, the close interactions of the two groups resulted in a cross-­fertilization of tool ideas and technologies that pushed TAU and Scalasca to what they are today. It also produced two performance systems with an increasing degree of functional overlap. While each tool has its specific analysis focus, the tools were implementing measurement infrastructures that were substantially similar. Because each tool provides complementary performance analysis, sharing of measurement results is valuable to provide the user with more facets to understand performance behavior. However, each measurement system was producing performance data in different formats, requiring data interoperability tools to be created. A common measurement and instrumentation system was needed to more closely integrate TAU and Scalasca and to avoid the duplication of development and maintenance effort.

    Full Text Available Introduction: Although nursing students spend a large part of their learning period in the clinical environment, clinical learning has not been perceived by its nature yet. To develop an instrument to measure effective factors on clinical learning in nursing students. Methods: This is a mixed methods study performed in 2 steps. First, the researchers defined “clinical learning” in nursing students through qualitative content analysis and designed items of the questionnaire based on semi-structured individual interviews with nursing students. Then, as the second step, psychometric properties of the questionnaire were evaluated using the face validity, content validity, construct validity, and internal consistency evaluated on 227 students from fourth or higher semesters. All the interviews were recorded and transcribed, and then, they were analyzed using Max Qualitative Data Analysis and all of qualitative data were analyzed using SPSS 14. Results: To do the study, we constructed the preliminary questionnaire containing 102 expressions. After determination of face and content validities by qualitative and quantitative approaches, the expressions of the questionnaire were reduced to 45. To determine the construct validity, exploratory factor analysis was applied. The results indicated that the maximum variance percentage (40.55% was defined by the first 3 factors while the rest of the total variance percentage (59.45% was determined by the other 42 factors. Results of exploratory factor analysis of this questionnaire indicated the presence of 3 instructor-staff, students, and educational related factors. Finally, 41 expressions were kept in 3 factor groups. The α-Cronbach coefficient (0.93 confirmed the high internal consistency of the questionnaire. Conclusion: Results indicated that the prepared questionnaire was an efficient instrument in the study of the effective factors on clinical learning as viewed by nursing students since it

    Despite a relatively poor understanding of Hawaiian groundwater systems, the State of Hawaii depends almost exclusively on groundwater for its public water supply. Ike Wai, an NSF funded project (EPSCoR Program Award OIA #1557349) at the University of Hawaii, aims to develop new groundwater models for Hawaii's aquifers, including water quality and transport processes. To better understand aquifer properties such as capacity and hydraulic conductivity, we are developing well-monitoring instruments that can autonomously record water parameters such as conductivity, temperature, and hydraulic head level, with sampling frequencies on the order of minutes. We are currently exploring novel methods and materials for solving classical design problems, such as applying dielectric spectroscopy techniques for measuring salinity, and using recycled materials for producing custom cable assemblies. System components are fabricated in house using rapid prototyping (e.g. 3D printing, circuit board milling, and laser cutting), and traditional manufacturing techniques. This approach allows us to produce custom components while minimizing development cost, and maximizing flexibility in the overall system's design.

    In experiments like ion implantation based ion track formations, the sample is implanted to low doses of the order of 10 10 ions/cm 2 , limiting the ion beam currents to be less than 1-5 x 10 -12 A. However the standard current integrators available are not sensitive to very low currents, causing an unacceptable high level of error in dose measurement. Hence a low dose implantation measurement system has been developed. It consists of a very sensitive low current preamplifier with full scale input 1nA/100pA, a standard current integrator, a microcontroller based interface circuit, which are connected to a personal computer(PC) through USB. Two types of the software are developed for the system: the microcontroller firmware using C and windows based virtual instrument programs using LabVIEW 7.0. Necessary precautions associated with pA level measurement like rigidly fastened good quality cables, low ripple DC power supply, shielding, close mounting of the preamplifier to the sample are adopted. After necessary calibrations with an ECIL make low current source, the system has been put into regular use. Design and development details, salient features are discussed in this paper. (author)

    Technology development requires an enormous financial investment over a long period of time. Scarce national and corporate resources, the result of highly competitive markets, decreased profit margins, wide currency fluctuations, and growing debt, often preclude continuous development of energy technology by single entities, i.e., corporations, institutions, or nations. Although the energy needs of the developed world are generally being met by existing institutions, it is becoming increasingly clear that existing capital formation and technology transfer structures have failed to aid developing nations in meeting their growing electricity needs. This paper will describe a method for meeting the electricity needs of the developing world through technology transfer and international cooperative technology development. The role of nuclear power and the advanced passive plant design will be discussed. (author)

    This report describes an External Review conducted by the LWRS Program Advanced Instrumentation, Information, and Control (II&C) Systems Technologies Pathway to solicit feedback on the topics and results of the ongoing II&C research program. This review was held in conjunction with the Nuclear Energy Institute (NEI) Digital I&C Working Group meeting that was held at Idaho National Laboratory (INL) on August 9-10, 2016. Given the opportunity to visit INL and see the pathway research projects, NEI agreed that the Working Group would serve as the External Review panel for the purpose of obtaining expert input on the value and timing of the research projects. This consisted of demonstrations in the Human Systems Simulation Laboratory followed by presentations on the II&C research program in general as well as the five technology development areas. Following the meeting, the presentations were sent to each of the attendees so they could review them in more detail and refer to them in completing the feedback form. Follow-up activities were conducted with the attendees following the meeting to obtain the completed feedback forms. A total of 13 forms were returned. The feedback forms were reviewed by the pathway to compile the data and comments received, which are documented in the report. In all, the feedback provided by the External Review participants is taken to be a strong endorsement of the types of projects being conducted by the pathway, the value they hold for the nuclear plants, and the general timing of need. The feedback aligns well with the priorities, levels of efforts allocated for the research projects, and project schedules. The feedback also represents realistic observations on the practicality of some aspects of implementing these technologies. In some cases, the participants provided thoughtful challenges to certain assumptions in the formulation of the technologies or in deployment plans. These deserve further review and revision of plans if warranted

    Munk, Michelle M.

    2006-01-01

    . Similar studies of Aerocapture applications at Neptune, Venus, and Mars were studied in 2003 through 2005. All showed significant performance improvements for the missions studied. Findings from these studies were used to guide the technology development tasks originally solicited in a 2002 NASA ROSS Research Announcement. The tasks are now in their final year and have provided numerous improvements in modeling and hardware, for use in proposals or new mission starts. Major Accomplishments: Since validation of the Aerocapture maneuver requires a space flight, ground developments have focused on modeling and environment prediction, materials, and sensors. Lockheed Martin has designed and built a 2-meter Carbon-Carbon aeroshell "hot structure." The article utilizes co-cured stiffening ribs and advanced insulation to achieve large scale, and up to a 40% reduction in areal density over the Genesis probe construction. This concept would be an efficient solution for probes that experience heat rates near 800-1000 W/cm(exp 2), such as at Venus and Earth. Applied Research Associates has extensively tested a family of efficient ablative TPS materials that provide solutions for a range of heating conditions. These materials are being applied to high-temperature structures built by ATK Space Systems, led by Langley Research Center. One-meter aeroshells will be thermally tested to validate construction and demonstrate higher bondline temperatures, which can lead to mass savings of up to 30% over traditional heatshields. Ames Research Center has developed aeroshell instrumentation that could measure environmental conditions and material performance during atmospheric entry. Instruments to measure TPS recession, heat flux, and catalycity could be combined with traditional sensors to provide a "plug-and-play" system for minimal mass and power, that would acquire flight data for model improvement and risk reduction on future missions. Improved atmospheric and aerothermodynamic models ha

    Measuring and evaluating patients' recovery, following intensive care, is essential for assessing their recovery process. By using a questionnaire, which includes spiritual and existential aspects, possibilities for identifying appropriate nursing care activities may be facilitated. The study describes the development and evaluation of a recovery questionnaire and its validity and reliability. A questionnaire consisting of 30 items on a 5-point Likert scale was completed by 169 patients (103 men, 66 women), 18 years or older (m=69, SD 12.5) at 2, 6, 12 or 24 months following discharge from an ICU. An exploratory factor analysis, including a principal component analysis with orthogonal varimax rotation, was conducted. Ten initial items, with loadings below 0.40, were removed. The internal item/scale structure obtained in the principal component analysis was tested in relation to convergent and discrimination validity with a multi-trait analysis. Items consistency and reliability were assessed by Cronbach's alpha and internal item consistency. Test of scale quality, the proportion of missing values and respondents' scoring at maximum and minimum levels were also conducted. A total of 20 items in six factors - forward looking, supporting relations, existential ruminations, revaluation of life, physical and mental strength and need of social support were extracted with eigen values above one. Together, they explained 75% of the variance. The half-scale criterion showed that the proportion of incomplete scale scores ranged from 0% to 4.3%. When testing the scale's ability to differentiate between levels of the assessed concept, we found that the observed range of scale scores covered the theoretical range. Substantial proportions of respondents, who scored at the ceiling for forward looking and supporting relations and at floor for the need of social support, were found. These findings should be further investigated. The factor analysis, including discriminant validity

    Computed tomography (CT), which uses penetrating radiation from many directions to reconstruct cross-sectional or 3D images of object, has widely applied in medical diagnosis and treatment, industrial NDT and NDE. So it is significant for college students to understand the fundamental of CT. The authors describe the CD-50BG CT instrument developed for experimental teaching at colleges. With 50 mm field-of-view and the translation-rotation scanning mode, the system makes use of a single plastic scintillator + photomultiplier detector and a 137 Cs radioactive source with 0.74 GBq activity, which is housed in a tungsten alloy shield. At the same time, an image processing software has been developed to process the acquired data, so that cross-sectional and 3D images can be reconstructed. High quality images with 1 lp·mm -1 spatial resolution and 1% contrast sensitivity are obtained. So far in China, more than ten institutions including Tsinghua University and Peking University have already applied the system to elementary teaching. (authors)

    Instrumentation, Controls, and Human-Machine Interface (ICHMI) technologies are essential to ensuring delivery and effective operation of optimized advanced Generation IV (Gen IV) nuclear energy systems. In 1996, the Watts Bar I nuclear power plant in Tennessee was the last U.S. nuclear power plant to go on line. It was, in fact, built based on pre-1990 technology. Since this last U.S. nuclear power plant was designed, there have been major advances in the field of ICHMI systems. Computer technology employed in other industries has advanced dramatically, and computing systems are now replaced every few years as they become functionally obsolete. Functional obsolescence occurs when newer, more functional technology replaces or supersedes an existing technology, even though an existing technology may well be in working order.Although ICHMI architectures are comprised of much of the same technology, they have not been updated nearly as often in the nuclear power industry. For example, some newer Personal Digital Assistants (PDAs) or handheld computers may, in fact, have more functionality than the 1996 computer control system at the Watts Bar I plant. This illustrates the need to transition and upgrade current nuclear power plant ICHMI technologies.

    Relying on coal for energy requires optimizing the extraction of heat content from various blends of coal fuel and reducing harmful constituents and byproducts. Having a real-time measurement instrument provides relevant information about toxic constituents released in the atmosphere from burning coal and optimizes the performance of a power plant. A few commercial instruments exist and have been in operation for more than a decade. However, most of these instruments are based on radioactive sources and are bulky, expensive and time-consuming. The proposed instrument is based on the Laser Induced Breakdown Spectroscopy (LIBS). The advantage of LIBS is that it is a standoff instrument, does not require sample preparation and provides precise information about sample constituents.

    1994-12-31

    In the development of advanced technologies, there are several forces which are involved in the success of the development of those technologies. In the overall development of new technologies, a sufficient number of these forces must be present and working in order to have a successful opportunity at developing, introducing and integrating into the marketplace a new technology. This paper discusses some of these forces and how they enter into the equation for success in advanced technology research, development, demonstration, commercialization and deployment. This paper limits itself to programs which are generally governmental funded, which in essence represent most of the technology development efforts that provide defense, energy and environmental technological products. Along with the identification of these forces are some suggestions as to how changes may be brought about to better ensure success in a long term to attempt to minimize time and financial losses.

    2003-01-01

    The NASA Glenn Research Center is developing small mobile platforms for sensor placement, as well as methods for communicating between roving platforms and a central command location. The first part of this project is to use commercially available equipment to miniaturize an existing sensor platform. We developed a five-circuit-board suite, with an average board size of 1.5 by 3 cm. Shown in the preceding photograph, this suite provides all motor control, direction finding, and communications capabilities for a 27- by 21- by 40-mm prototype mobile platform. The second part of the project is to provide communications between mobile platforms, and also between multiple platforms and a central command location. This is accomplished with a low-power network labeled "SPAN," Sensor Platform Area Network, a local area network made up of proximity elements. In practice, these proximity elements are composed of fixed- and mobile-sensor-laden science packages that communicate to each other via radiofrequency links. Data in the network will be shared by a central command location that will pass information into and out of the network through its access to a backbone element. The result will be a protocol portable to general purpose microcontrollers satisfying a host of sensor networking tasks. This network will enter the gap somewhere between television remotes and Bluetooth but, unlike 802.15.4, will not specify a physical layer, thus allowing for many data rates over optical, acoustical, radiofrequency, hardwire, or other media. Since the protocol will exist as portable C-code, developers may be able to embed it in a host of microcontrollers from commercial to space grade and, of course, to design it into ASICs. Unlike in 802.15.4, the nodes will relate to each other as peers. A demonstration of this protocol using the two test bed platforms was recently held. Two NASA modified, commercially available, mobile platforms communicated and shared data with each other and a

  2. Field estimation of soil water content. A practical guide to methods, instrumentation and sensor technology

    International Nuclear Information System (INIS)

    2008-01-01

    During a period of five years, an international group of soil water instrumentation experts were contracted by the International Atomic Energy Agency to carry out a range of comparative assessments of soil water sensing methods under laboratory and field conditions. The detailed results of those studies are published elsewhere. Most of the devices examined worked well some of the time, but most also performed poorly in some circumstances. The group was also aware that the choice of a water measurement technology is often made for economic, convenience and other reasons, and that there was a need to be able to obtain the best results from any device used. The choice of a technology is sometimes not made by the ultimate user, or even if it is, the main constraint may be financial rather than technical. Thus, this guide is presented in a way that allows the user to obtain the best performance from any instrument, while also providing guidance as to which instruments perform best under given circumstances. That said, this expert group of the IAEA reached several important conclusions: (1) the field calibrated neutron moisture meter (NMM) remains the most accurate and precise method for soil profile water content determination in the field, and is the only indirect method capable of providing accurate soil water balance data for studies of crop water use, water use efficiency, irrigation efficiency and irrigation water use efficiency, with a minimum number of access tubes; (2) those electromagnetic sensors known as capacitance sensors exhibit much more variability in the field than either the NMM or direct soil water measurements, and they are not recommended for soil water balance studies for this reason (impractically large numbers of access tubes and sensors are required) and because they are rendered inaccurate by changes in soil bulk electrical conductivity (including temperature effects) that often occur in irrigated soils, particularly those containing

    Uranium kernel fabrication technology using a wet chemical so-gel method, a key technology in the coated particle fuel area, is established up to the calcination step and the first sintering of UO2 kernel was attempted. Experiments on the parametric study of the coating process using the surrogate ZrO2 kernel give the optimum conditions for the PyC and SiC coating layer and ZrC coating conditions were obtained for the vaporization of the ZrCl4 precursor and coating condition from ZrC coating experiments using plate-type graphite substrate. In addition, by development of fuel performance analysis code a part of the code system is completed which enables the participation to the benchmark calculation and comparison in the IAEA collaborated research program. The technologies for irradiation and post irradiation examination, which are important in developing the HTGR fuel technology of its first kind in Korea was started to develop and, through a feasibility study and preliminary analysis, the technologies required to be developed are identified for further development as well as the QC-related basic technologies are reviewed, analyzed and identified for the own technology development. Development of kernel fabrication technology can be enhanced for the remaining sintering technology and completed based on the technologies developed in this phase. In the coating technology, the optimum conditions obtained using a surrogate ZrO2 kernel material can be applied for the uranium kernel coating process development. Also, after completion of the code development in the next phase, more extended participation to the international collaboration for benchmark calculation can be anticipated which will enable an improvement of the whole code system. Technology development started in this phase will be more extended and further focused on the detailed technology development to be required for the related technology establishment

    Alcatel Alenia Space and ECM have jointly developed a new ceramic material to produce lightweight, stiff, stable and cost effective structures and mirrors for space instrument the CesicÒ. Its intrinsic properties, added to ample manufacturing capabilities allow to manufacture stiff and lightweight cost effective mirrors and structure for space instruments. Different scale 1 flight representative CesicÒ optical structures have been manufactured and successfully tested under very strong dynamic environment and cryogenic condition down to 30K CesicÒ is also envisaged for large and lightweight space telescopes mirrors, a large CesicÒ 1 meter class mirror with an area mass of less than 25 Kg/m2 has been sized again launch loads and WFE performance and manufactured. CesicÒ applicability for large focal plane have been demonstrated through different scale 1 breadboards. Based on these successful results, AlcatelAleniaSpace and ECM are now in position to propose for space this technology with new innovative concepts thanks to the CesicÒ manufacturing capabilities. CesicÒ has therefore been selected for the structure and mirrors parts of a flight instrument payload and the manufacturing of the flight hardware is already underway. An high temperature high gain lightweight antenna breadboard is also under manufacturing for Bepi colombo mission. CesicÒ is therefore a good candidate for future challenging space instruments and is currently proposed for Japan and US space projects.

    This paper describes the development of the Chinese Quality of Life Instrument (ChQOL) which is a self-report health status instrument. Chinese Medicine relies very much on asking subjective feelings of patients in the process of diagnosis and monitoring of treatment. For thousands of years, Chinese Medicine practitioners have accumulated a good wealth of experiences in asking questions about health of their patients based on the concept of health in Chinese Medicine. These experiences were then transformed into questions for the ChQOL. It is believed that ChQOL can contribute to the existing Patient Report Outcome measures. This paper outlines the concept of health and disease in Traditional Chinese Medicine, the building of the conceptual framework of the ChQOL, the steps of drafting, selecting and validating the items, and the psychometric properties of the ChQOL. The development of the ChQOL was based on the concept of health in Traditional Chinese Medicine with a theory driven approach. Based on the results of literature review, the research team developed an initial model of health which encompassed the concept of health in TCM. An expert panel was then invited to comment and give suggestions for improvement of the initial model. According to their suggestions, the model was refined and a set of initial items for the ChQOL was drafted. The refined model, together with the key domains, facets and initial items of the ChQOL were then mailed to a sample of about 100 Chinese medicine practitioners throughout Mainland China for their comments and advice. A revised set of items were developed for linguistic testing by a convenience sample consisting of both healthy people and people who attended Chinese Medicine treatment. After that, an item pool was developed for field-testing.

    This project investigated technologies that may reduce environmental pollution. This was a basic research/educational project addressing two major areas: A. In the algae research project, newly isolated strains of microalgae were investigated for feedstock production to address the production of renewable fuels. An existing collection of microalgae was screened for lipid composition to determine strains with superior composition of biofuel molecules. As many microalgae store triacylglycerides in so-called oil bodies, selected candidate strains identified from the first screen that accumulate oil bodies were selected for further biochemical analysis, because almost nothing was known about the biochemistry of these oil bodies. Understanding sequestration of triacylglycerides in intracellular storage compartments is essential to developing better strains for achieving high oil productivities by microalgae. At the onset of the project there was almost no information available on how to obtain detailed profiles of lipids from strains of microalgae. Our research developed analytical methods to determine the lipid profiles of novel microalgal strains. The project was embedded into other ongoing microalgal projects in the Polle laboratory. The project benefited the public, because students were trained in cell cultivation and in the operation of state-of-the-art analytical equipment. In addition, students at Brooklyn College were introduced into the concept of a systems biology approach to study algal biofuels production. B. A series of new nanostructured catalysts were synthesized, and characterized by a variety of physical and chemical methods. Our catalyst design leads to active nanostructures comprising small metal particles in intimate contact with strongly basic sites provided by the supports, which include poly(4-vinylpyridine), magnesium oxide, functionalized multi-walled carbon nanotubes, and graphene oxide. The new materials display a good potential as catalysts

  12. Development of perceived instrumentality for mathematics, reading and science curricula

    Science.gov (United States)

    Garcia, Steve L.

    Perceptions of instrumentality (PI) are the connections one sees between a current activity and a future goal. With high PI, one is motivated to persist with quality effort because the current activity, even when difficult, is perceived as aligned with, and progress toward, the goal. Conversely, with low PI, one is motivated to relinquish effort in pursuit of other, more meaningful goals. In view of the alarming dropout rates in this country, it appears that PI research has much to offer in understanding students' motivations to stay in school and hence to become employed in their field of choice. Because academic achievement motivation can be affected by gender and ethnicity, particularly for specific components of the curriculum, and because curricular content varies across grade levels and school settings, this line of research offers significant potential for understanding and improving student outcomes. This research examined the development of PI among suburban 6th, 8th, 10th and 12th graders from a school district in the southwestern United States. Twelve hundred students completed a one-time paper and pencil survey measuring the perceived instrumentality of mathematics, literacy and science courses in terms of the students' occupational choices. MANOVA was used to determine factors that may affect students' overall PI and individual subject PI. Grade, gender, ethnicity, occupational choice, expectancy and value were the independent variables. A school setting variable was examined for effects on 12th graders. For the 8th through 12th grade sample, significant main effects were observed for grade, gender, minority status, occupational choice and expectancy on PI. Results show that PI is highest in the 6 th grade. Males reported higher Math PI than females. Females reported higher Reading PI and Science PI than males. Minority students reported lower overall PI and Science PI than non-minority students. Students who aspire to professional careers report the

    The objective of this study, conducted in Bolivia from April to July of 2008, is the design and validation of an initial nursing assessment instrument to be used in clinical and educational environments in Santa Cruz (Bolivia). Twelve Bolivian nurses participated; both document analysis as well as consensus techniques were used to determine the categories and criteria to be assessed. Categories included in the nursing assessment instrument are a physical assessment and the eleven Gordon's Functional Health Patterns. The nursing assessment instrument stands out as being concise, easy to complete and utilizing a nursing approach. It does not include items for advanced nursing assessment. However, it incorporates items regarding lifestyle and the patient's autonomy. The nursing assessment instrument contributes to improving the quality of clinical records, supports the nursing diagnosis and implementation of the nursing process, promotes the nurse's role and helps to standardize practice.

    This study sought to develop a self-report instrument to be used in the assessment of the project competences of college students engaged in online project-based learning. Three scales of the KIPSSE instrument developed for this study, namely, the knowledge integration, project skills, and self-efficacy scales, were based on related theories and the analysis results of three project advisor interviews. Those items of knowledge integration and project skill scales focused on the integration of different disciplines and technological skills separately. Two samples of data were collected from information technology-related courses taught with an online project-based learning strategy over different semesters at a college in southern Taiwan. The validity and reliability of the KIPSSE instrument were confirmed through item analysis and confirmatory factor analysis using structural equation modeling of two samples of students' online response sets separately. The Cronbach's alpha reliability coefficient for the entire instrument was 0.931; for each scale, the alpha ranged from 0.832 to 0.907. There was also a significant correlation ( r = 0.55, p < 0.01) between the KIPSSE instrument results and the students' product evaluation scores. The findings of this study confirmed the validity and reliability of the KIPSSE instrument. The confirmation process and related implications are also discussed.

  16. Research reactor instrumentation and control technology. Report of a technical committee meeting

    International Nuclear Information System (INIS)

    1997-10-01

    The majority of research reactors operating today were put into operation 20 years ago, and some of them underwent modifications, upgrading and refurbishing since their construction to meet the requirements for higher neutron fluxes. However, a few of these ageing research reactors are still operating with their original instrumentation and control systems (I and C) which are important for reactor safety to guard against abnormal occurrences and reactor control involving startup, shutdown and power regulation. Worn and obsolete I and C systems cause operational problems as well as difficulties in obtaining replacement parts. In addition, satisfying the stringent safety conditions laid out by the nuclear regulatory bodies requires the modernization of research reactors I and C systems and integration of additional instrumentation units to the reactor. In order to clarify these issues and to provide some guidance to reactor operators on state-of-art technology and future trends for the I and C systems for research reactors, a Technical Committee Meeting on Technology and Trends for Research Reactor Instrumentation and Controls was held in Ljubljana, Slovenia, from 4 to 8 December 1995. This publication summarizes the discussions and recommendations resulting from that meeting. This is expected to benefit the research reactor operators planning I and C improvements.

    Full Text Available The assessment of the most informative methods of diagnostics of mechanisms with electric drive has been given; their realization in a measuring complex on the basis of the virtual device has been considered. The comparative analysis of vibration methods for the analysis of current spectra and the thermal method of nondestructive testing has been carried out. It has been stated that methods of vibration diagnostics are more sensitive to defects in the mechanical part of the electric drive (determination of defects in bearing assemblies, misalignment of shafts, imbalance of rotating parts. Analysis of the current spectrum at the early stage has shown the defects of rotor windings, static and dynamic rotor eccentricity. The temperature of the bearing assemblies and the stator (the thermal control method indicates the defects in lubrication and cooling systems. The set of methods of nondestructive control allows increase the completeness and reliability of diagnosis of the mechanism with electric drive. The optimal solution to realize into one measuring instrument all methods of diagnostics is to use the technology of virtual instruments. The list of components for the measuring part of the complex and the functional scheme of the program for processing the results have been given. Spectra of vibration of defective mechanisms have been obtained with the help of the measuring complex based on the virtual instrument. Some recommendations have been given on the introduction of the virtual appliance in the State register of measuring instruments.

    Licensees of commercial nuclear power plants in the US are expected to submit license renewal applications for the period of operation of 60 to 80 years which has also been referred to as long term operation (LTO). The greatest challenges to LTO are associated with degradation of passive components as active components are routinely maintained and repaired or placed through maintenance programs. Some passive component degradation concerns include stress corrosion cracking (SCC) of metal components, radiation induced embrittlement of the reactor pressure vessel (RPV), degradation of buried piping, degradation of concrete containment structures, and degradation of cables. Proactive management of passive component aging employs three important elements including online monitoring of degradation, early detection of degradation at precursor stages, and application of prognostics for the prediction of remaining useful life (RUL). This document assesses several nondestructive examination (NDE) measurement technologies for integration into proactive aging management programs. The assessment is performed by discussing the three elements of proactive aging management identified above, considering the current state of the industry with respect to adopting these key elements, and analyzing measurement technologies for monitoring large cracks in metal components, monitoring early degradation at precursor stages, monitoring the degradation of concrete containment structures, and monitoring the degradation of cables. Specific and general needs have been identified through this assessment. General needs identified include the need for environmentally rugged sensors are needed that can operate reliably in an operating reactor environment, the need to identify parameters from precursor monitoring technologies that are unambiguously correlated with the level of pre-macro defect damage, and a methodology for identifying regions where precursor damage is most likely to initiate.

    MWIR (Mid-Wave Infrared) spectroscopy shows a large potential in the current IR devices market, due to its multiple applications, such as gas detection, chemical analysis, industrial monitoring, combustion and flame characterization. It opens this technique to the fields of application, such as industrial monitoring and control, agriculture and environmental monitoring. However, a major barrier, which is the lack of affordable specific key elements such a MWIR light sources and low cost uncooled detectors, have held it back from its widespread use. In this paper an uncooled MWIR detector combined with image enhancement technique is reported. This investigation shows good results in gas leakage detection test. It also verify the functions of self-developed MWIR lens and optics. A good agreement in theoretical design and experiment give us the lessons learned for the potential application in infrared satellite technology. A brief discussions will also be presented in this paper.

    New instrumentation and control technologies must be justified for application in power plants on the basis of improved plant performance and reduced investment costs. This justification requires that capability differences among systems be identified and that implementation schemes be selected which permit meaningful comparisons. A simple evaluation of initial investment costs is frequently inadequate because it does not account for operational expenses or resulting changes in plant performance. As an example of a more comprehensive evaluation methodology, this paper reviews the procedures and results from a recently completed study of remote multiplexing funded by the Electric Power Research Institute (EPRI). In this study it was found that plant-wide multiplexing of non-safety instrumentation and control signals is technically feasible, can be designed to satisfy availability requirements, may save millions of dollars as a hardwire replacer, and can provide other significant intangible benefits.

    The Lunar Surface Systems Supportability Technology Development Roadmap is a guide for developing the technologies needed to enable the supportable, sustainable, and affordable exploration of the Moon and other destinations beyond Earth. Supportability is defined in terms of space maintenance, repair, and related logistics. This report considers the supportability lessons learned from NASA and the Department of Defense. Lunar Outpost supportability needs are summarized, and a supportability technology strategy is established to make the transition from high logistics dependence to logistics independence. This strategy will enable flight crews to act effectively to respond to problems and exploit opportunities in an environment of extreme resource scarcity and isolation. The supportability roadmap defines the general technology selection criteria. Technologies are organized into three categories: diagnostics, test, and verification; maintenance and repair; and scavenge and recycle. Furthermore, "embedded technologies" and "process technologies" are used to designate distinct technology types with different development cycles. The roadmap examines the current technology readiness level and lays out a four-phase incremental development schedule with selection decision gates. The supportability technology roadmap is intended to develop technologies with the widest possible capability and utility while minimizing the impact on crew time and training and remaining within the time and cost constraints of the program.

    Biomass gasification offers a practical way to use this locally available fuel source for co-firing traditional large utility boilers. The gasification process converts biomass into a low Btu producer gas that can be fed directly into the boiler. This strategy of co-firing is compatible with a variety of conventional boilers including natural gas fired boilers as well as pulverized coal fired and cyclone boilers. Gasification has the potential to address all problems associated with the other types of co-firing with minimum modifications to the existing boiler systems. Gasification can also utilize biomass sources that have been previously unsuitable due to size or processing requirements, facilitating a reduction in the primary fossil fuel consumption in the boiler and thereby reducing the greenhouse gas emissions to the atmosphere.

    The Dark Energy Spectroscopic Instrument (DESI) is under construction to measure the expansion history of the universe using the baryon acoustic oscillations technique. The spectra of 35 million galaxies and quasars over 14,000 square degrees will be measured during a 5-year survey. A new prime focus corrector for the Mayall telescope at Kitt Peak National Observatory will deliver light to 5,000 individually targeted fiber-fed robotic positioners. The fibers in turn feed ten broadband multi-object spectrographs. We describe the ProtoDESI experiment, that was installed and commissioned on the 4-m Mayall telescope from 2016 August 14 to September 30. ProtoDESI was an on-sky technology demonstration with the goal to reduce technical risks associated with aligning optical fibers with targets using robotic fiber positioners and maintaining the stability required to operate DESI. The ProtoDESI prime focus instrument, consisting of three fiber positioners, illuminated fiducials, and a guide camera, was installed behind the existing Mosaic corrector on the Mayall telescope. A fiber view camera was mounted in the Cassegrain cage of the telescope and provided feedback metrology for positioning the fibers. ProtoDESI also provided a platform for early integration of hardware with the DESI Instrument Control System that controls the subsystems, provides communication with the Telescope Control System, and collects instrument telemetry data. Lacking a spectrograph, ProtoDESI monitored the output of the fibers using a fiber photometry camera mounted on the prime focus instrument. ProtoDESI was successful in acquiring targets with the robotically positioned fibers and demonstrated that the DESI guiding requirements can be met.

    Technology transfer is often mentioned as an ancillary benefit of the Kyoto Protocol's Clean Development Mechanism (CDM), but this claim has never been researched or substantiated. The question of technology transfer is important from two perspectives: for host countries, whether the CDM provides a corridor for foreign, climate-friendly technologies and investment, and for industrialised countries as it provides export potential for climate-friendly technologies developed as a consequence of stringent greenhouse gas targets. In order to better understand whether technology transfer from the EU and elsewhere is occurring through the CDM, and what is the value of the associated foreign investment, this paper examines technology transfer in the 63 CDM projects that were registered on January 1st, 2006. Technology originates from outside the host country in almost 50% of the evaluated projects. In the projects in which the technology originates from outside the host country, 80% use technology from the European Union. Technologies used in non-CO2 greenhouse gas and wind energy projects, and a substantial share of the hydropower projects, use technology from outside the host country, but biogas, agricultural and biomass projects mainly use local technology. The associated investment value with the CDM projects that transferred technology is estimated to be around 470 million Euros, with about 390 coming from the EU. As the non-CO2 greenhouse gas projects had very low capital costs, the investment value was mostly in the more capital-intensive wind energy and hydropower projects

    The main objectives of this thesis are: to investigate technological change and cost reduction for a number of renewable electricity technologies by means of the experience curve approach; to address related methodological issues in the experience curve approach, and, based on these insights; and to analyze the implications for achieving the Dutch renewable electricity targets for the year 2020 within a European context. In order to meet these objectives, a number of research questions have been formulated: What are the most promising renewable electricity technologies for the Netherlands until 2020 under different technological, economic and environmental conditions?; To what extent is the current use of the experience curve approach to investigate renewable energy technology development sound, what are differences in the utilization of this approach and what are possible pitfalls?; How can the experience curve approach be used to describe the potential development of partially new energy technologies, such as offshore wind energy? Is it possible to describe biomass fuel supply chains with experience curves? What are the possibilities and limits of the experience curve approach when describing non-modular technologies such as large (biomass) energy plants?; What are the main learning mechanisms behind the cost reduction of the investigated technologies?; and How can differences in the technological progress of renewable electricity options influence the market diffusion of renewable electricity technologies, and what implications can varying technological development and policy have on the implementation of renewable electricity technologies in the Netherlands? The development of different renewable energy technologies is investigated by means of some case studies. The possible effects of varying technological development in combination with different policy backgrounds are illustrated for the Netherlands. The thesis focuses mainly on the development of investment

    Radiation shielding analysis in nuclear engineering fields is an important technology which is needed for the calculation of reactor shielding as well as radiation related safety problems in nuclear facilities. Moreover, the design technology required in high level radioactive waste management and disposal facilities is faced on serious problems with rapidly glowing nuclear industry development, and more advanced technology has to be developed for tomorrow. The main purpose of this study is therefore to build up the self supporting ability of technology development for the radiation shielding analysis in order to achieve successive development of nuclear industry. It is concluded that basic shielding calculations are possible to handle and analyze by using our current technology, but more advanced technology is still needed and has to be learned for the degree of accuracy in two-dimensional shielding calculation.
