    For efficient medical care supply systems, the R and D of advanced medical care technology and equipment largely contribute to productivity improvement for medical care services. Among them, a progress of medical care technology is becoming important for preparation of efficient and fair supply systems. MITI thus established 'Medical care and welfare equipment development project' in 1994, and has promoted the strategic long-term R and D project of medical care and welfare equipment as joint R and D project of NEDO and private enterprises. In fiscal 1998, on the development of the fine sampling/analysis system for blood, the high- precision 3-D image diagnosis system, the low-invasion operation support system, and the artificial internal organ technologies since fiscal 1996, this project clarified essential technical issues based on the future view, selected some themes to be newly developed in the future, and surveyed and evaluated the details of their R and D concretely.

    Fuji Electric Co., Ltd., in collaboration with Shitashion Japan and Arthur Andersen Ltd., developed a 'marketing analysis support system' which integrally analyzes evaluation factors of various dimensions explaining consumers' purchasing behaviors and which supports business for the efficient operation of product development and demand prediction. This system breaks down products into each evaluation factor from psychological and physical viewpoints, and carries out various kinds of multivariate analysis, thereby making it easy to understand visually, for example, what evaluation factors decide relative positional relations between evaluation factors or between products as well as the position of a product in the whole. Further, more precise marketing analysis and prediction become possible by visually grasping blank areas of products, extent of competition, distribution of products, composition of product series, etc. (translated by NEDO)

    Vapor-liquid equilibria of a water + 1-butanol system containing a trace amount of furfural were measured at atmospheric pressure by use of a Iino-type still for systems of limited miscibility. Vapor-liquid compositions for the major components (water and 1-butanol) are shown to be nearly coincident with those of the binary system. In the partially miscible region, the vapor-liquid equilibrium ratios of the trace component (furfural) at bubble point were found to be 2.5 and 0.46. Consequently, the partition coefficient of the trace component between the two liquid phases is 5.4. The equilibrium ratio curve of the trace component is presented, in which the calculated curve within the partially miscible region is shown to be coincident with the experimental data. 5 refs., 3 figs., 1 tab.

    Vapor-liquid equilibria of a water-methanol-ethanol system containing a minute amount of furfural were measured at atmospheric pressure by use of an Othmer-type still. The experimental results are represented by four triangular diagrams against the liquid compositions of the major components (water, methanol and ethanol), in which three diagrams show the vapor composition of the major components, respectively, and one diagram shows the equilibrium ratio of the trace component (furfural). The curved surface of the equilibrium ratio of the trace component exhibits a gentle downward slope in most areas, but shows a half-saddle face in the neighborhood of the water-ethanol side. 4 refs., 10 figs., 3 tabs.

    In order to complement an anomaly diagnosis system by analysis of gases in oil for transformers, the analysis/diagnosis method of trace constituents in oil was developed. Liquid-liquid solvent extraction using methanol aqueous solution as extract, and high-speed liquid chromatography were adopted to analyze decomposed products dissolved into oil by over heating as trace constituents. The relation between over heat temperature and the amount of decomposed products by over heating was studied by simulation experiment of over heat anomaly. The detectable duration of anomaly after its generation was also studied by examining the adsorption phenomenon of the thermal decomposed products onto insulating materials. As a result, the criterion of the analysis/diagnosis method was prepared by using 5-hydroxymethylfurfural as index constituent of over heating anomaly. Although furfural was also effective as index constituent, it was excluded from the index constituent because furfural is formed by deterioration of transformers even during normal operation. 2 refs., 19 figs., 7 tabs.

    Inquiries are made to consumers (monitors) who own a photovoltaic power generation system at their houses, and their replies are analyzed for isolating the factors involving the purchase of this domestic power generating system. A large part of the monitors are 40-50 years old males in the relatively high income bracket. They are very interested in problems of global environments, resources, and energy, and are inclined to assume value-consciousness and life-style which encourage them to love health and nature, participation in social functions, and decision-making. The need for the protection of global environments occupies more than 90% of the reasons for their adoption of photovoltaic power generation. The monitors strongly feel, however, that they paid very much for the apparatus although they were granted some subsidies. As for motives for their acquisition of the system, their answers are categorized into four groups according to their responses as to whether (or not) they expect economic merits though dependent on future development and whether (or not) they accept the current energy policies. The result shows that some monitors think like average citizens. 17 refs., 22 figs., 11 tabs.

    The systems in American and European countries for technological development of welfare-related equipment and tools are surveyed and analyzed, with the objectives to draw proposals for establishing the systems which help smooth spread of the research/development results. It is necessary, in selecting the research themes, to well balance the supports for research and development based on the ideas and initiatives by the researchers with those for the publicly invited themes in which the government narrows down the politically important items. For exchanging researchers, the program should help exchange researchers routinely, to match the needs and seeds. It is necessary for the research and development programs promoted by the government for welfare-related equipment to quantitatively grasp the characteristics of various body functions and deterioration of these functions by aging, and to encourage the new participants by providing them with the databases. For promotion of spreading the R and D results, it is necessary to develop laws and regulations which help reduce expenses of the individual disabled and aged, and promote purchase of equipment through insurance, like ADA and rehabilitation-related laws adopted by USA.

    As an energy conservation promotion measure, a project is under development for introducing and subsidizing high-efficiency energy systems and for letting their effect known publicly and widely. The number of proposed energy systems has increased greatly and technical divisions to follow in classifying them have become vague, from which problems are now arising over the execution of follow-up checks and the maintenance of fair treatment. In the effort to solve this problem, 376 propositions are analyzed and classified, a technical classification method is proposed, and an instruction manual on the method is compiled. The classification involves (1) proposed classification, (2) variation, (3) energy reduction rate, and (4) tentatively calculated cost. Item (1) deals with the basic classification (air-conditioning, ventilation, and hot water supply, and, to be considered in combination with them, options which are cooking, illumination, and others) and, item (2) covers eight items such as new/old construction, structure, and structural frame. In Chapter 1 of the report, the 376 propositions are put in order according to common classification items and an original classification table is prepared. In Chapter 2, the goals are clarified and the classification principles are defined. In Chapter 3, the classification is checked for its validity and some realistic ways of grouping are described. In Chapter 4, a classification implementation flow chart is shown. (NEDO)

    Using the vitellogenin levels in male fishes as a parameter of pollution caused by internal secretion disturbing substances would allow collective measurement of compounding action of pollutants, acquisition of time averaged values, and large reduction in analysis cost. The present research and development works are intended to put such technological seeds into practical use, and promote its proliferation. The following subjects were implemented: (1) fabrication of effective anti-bodies, (2) their application to fresh water fishes, salmon, and trout, (3) their application to sea water fishes, (4) effects on mummichog and medaka, (5) correlation between spawning actions and vitellogenin manifestation in male fish, (6) discussions on chemical analysis methods and the correlativity therewith, and (7) establishment of methods for field investigation and evaluation. In Item (1), an ELISA system using vitellogenin anti-bodies of different fishes was established. A universal anti-body reacting commonly to all of fish vitellogenins was developed. In Items (2), (3) and (4), an evaluation system was established on actions of internal secretion disturbing substances on sea water fish and fresh water fish by using fish vitellogenins. In Item (5), effects on spawning of medaka, and effects on procreation activities (sterility) were evaluated by using vitellogenin. (NEDO)

    Distribution of probabilities of solar radiation fluctuation was examined to learn the fluctuation in photovoltaic power generation efficiency for the purpose of improving on the generation system. The measuring setup comprised one base station and nine terminal stations. The terminal stations were arrayed in lattice so that a 4km{times}4km-large area would be covered. The standard deviation in solar radiation fluctuation at an observation spot ANNE stayed constant at approximately 0.1kW/m{sup 2} at all observation hours. In the vicinity of a clearness index range of 0.5-0.6 (a higher index showing a clearer weather) in the daytime, the index fluctuated very much, predicting a half-clear sky with scattered cloud. In the range of 0.2-0.3, fluctuation was small. In the range of 0.6-0.7, fluctuation was small and solar radiation was stable under the clear sky. The scope of fluctuation in the areal average is smaller than that in the average at each of the terminal stations, which is explained by the even-out effect. This means that, if multiple PV systems concentratedly introduced into one region are appropriately coordinated, the outputs from the individual PV systems that are naturally inconsistent are evened out and that the reliability of the network as a whole is consequently enhanced. 5 refs., 7 figs., 1 tab.

    Arrangement, investigation and analysis of an energy information exchange system were conducted, with the aim of coping with the development in the whole Asia/Pacific area, the stabilization of energy supply/demand, and the environmental problem and of realizing effective cooperation of every country in the area. Concerning the trend of the domestic primary energy supply/demand, there are some patterns. Countries which show high growth rates are developing countries such as Thailand and China, and NIES such as Korea and Taiwan. Countries where growth rates are slowing down and lowering are developed countries such as Australia, Canada, Japan and the U.S. Countries where energy supply/demand is not stabilized are Singapore, Hong Kong, Indonesia and Chile which are suffering from variations in import/export. The ultimate energy consumption is the domestic primary energy supply from which the conversion loss in the conversion sector was deducted, and indicates almost the same trend as the primary energy supply. It is divided into a stabilized type of developed countries and a rapidly increasing type and a stagnant type. However, there are some exceptions. Total data in the quarter of the year cannot be the yearly data by itself, but requires a year-end tax arrangement. 40 tabs.

In the simulation, assumed were a standard case, aging/hollowing case, and technical innovation case. As to macroeconomic models, macro items such as the economic growth rate, prices and IS balance were determined by giving foreign factors, financial factors, population factors, etc. In long-term energy supply/demand models, data on demand by use in commercial/residential and transportation sectors were estimated using various statistics. About the calculation result of a standard case of the former sector, the existing industries which markedly ebbed are primary products, the material system, construction/civil engineering, etc. Contrarily, the production industry such as general machines, electrical machines and automobiles increased the share. New and highly growing industries are new production industries like electronics and communication and new services like finance, insurance and communication.

    For measuring trace pollutants and for establishing a simplified high-speed method of assessing their impacts, research and development efforts are exerted to build measuring devices to meet the purpose. In relation with air pollutants, researches are conducted to develop a passive sampler technology-aided measuring devices capable of on-site analyses of trace pollutants. For the development of microchips to be the nuclei of such devices, studies are conducted about a gas absorbing chip consisting of porous quartz glass and a passive sampler installed thereon, a chemical reaction chip on which absorbed NO{sub 2} ions react with a fluorescent reagent, and an optical detection chip capable of high-sensitivity detection of a fluorescent substance generated by an ultraviolet emission device. As the result, an A4 size prototype of a trace NO{sub 2} measuring device is developed using a fluorescence detecting microchip system. In addition, a simplified measuring device is developed, in which gas absorbed at a polymer film flows in a very thin plastic-formed channel to reach an electrochemical detection system for measurement, and the device is found to work effectively.

    An end use model used in the United States who is advanced in demand-side management (DSM) was used to discuss possibilities of designing and evaluating Japan`s future DSM measures. The end use model assumes energy demand based on such factors as device characteristics, meteorological data, energy prices, user characteristics, market characteristics and DSM measures. The model calculates energy demand amount by end uses basically by multiplying assumptions on device unit requirement, device retention rate, and number of users. A representative tool as an end use model that handles load shapes is the hourly electric load model (HELM). It assumes an annual load curve and predicts a maximum system load. The present discussions have performed estimation on demand for consumer use air conditioners in a day in which a maximum summer load occurs in a reference year, estimation on load in a maximum load day in an estimated year, and estimation on weather sensitivity of loads. 5 refs., 5 figs.

    A method to inspect the rattle, one of the transient noises of car interior, is developed. In the method, the waveform data of overall noise are analyzed using Wigner distribution, and its rattle component is condensed and separated from the background excitation noise. Then the rattle component is classified into three levels: strong, middle and none, using the neural network. A fuzzy inference is also used to select regular waveform measurements. Experimental results show that the correct classification ratio of the method is more than 90%, which equals skilled inspection operators in accuracy. 11 refs., 8 figs.

    Hydrogen gas as material is produced mostly by steam reforming of hydrocarbons, and includes a considerable amount of impurities such as carbon dioxide, nitrogen and oxygen. The concentration of impurities in the refined gas is approximately 1ppm. In the liquefaction process of hydrogen liquefaction plant, the gases entering the low temperature portion near the free expansion valve (J-T valve) are mostly oxygen and nitrogen. When oxygen is solidified, attached, accumulated near J-T valve, it incurs a possibility of exploding for reason of impact force, etc. by contact with the valve portion. A mixture of hydrogen and oxygen ignites at the minimum value of approximately 0.02 milli-joule, and therefore it has great danger of explosion. As viewed from a point of danger prevention, there is a possibility of explosion when the hydrogen-oxidizing agent mixture is formed. Accordingly, it is necessary to conduct an experiment for confirming the explosion at J-T valve portion. From viewpoints of prevention of explosion accident and running operation, it is necessary to experimentally grasp the definite allowable oxygen concentration. Further, it is necessary to establish a technology to continuously and accurately measure the concentration of trace impurities in hydrogen gas. (NEDO)

    This report describes the impact assessment which is an important step for LCA. For classification of the impact assessment, the existing literature was reviewed and a skeleton for the classification was proposed. The weighting factors for nine selected impact categories, which were used to calculate environmental load point (ELP) for the valuation, were obtained for two overseas groups, i.e., students of Amsterdam University and SETAC Europe members. It was found that the former provided the similar trends to general Japanese, however that the latter gave high weighting in the global warming and depletion of ozone layer. The ELP was proposed and applied to automatic washing machine, coffee maker, waste incineration power generation system, and co-generation system. As a result, its effectiveness was demonstrated. This report also describes problems for the LCA of thermal and material recycling of PS trays. 99 refs., 96 figs., 73 tabs.

    We have developed a systematic design task planning method based on a design structure matrix(DSM) and a lumped model- based framework for knowledge sharing in a concurrent design environment as key techniques for developing higher quality products in a shorter design time. The DSM facilitates systematic analysis of dependencies among design tasks and optimization of the design process. The framework based on a lumped model description of mechanical systems enables concurrent and cooperative work among multidisciplinary designers at an early stage of the design process. In this paper, we also discuss the relationships between these techniques and the product development flow from product definition to detailed design. (author)

    A simplified method is developed, which measures dioxins in flue gas without using GC/MS (gas chromatography/mass spectrometry) of the double focusing type. The sampling device is built of two collecting bottles, containing water and diethylene glycol, and uses no XAD-2 (cross-linked amberlight divinyl benzene) resin. Such a design does not need time consuming Soxlet extraction in the sampling process and shortens the processing time. An HPLC (high performance liquid chromatography) system replaces the convenient column chromatography system in the cleanup process, and this enables automation and rapid treatment. For the measurement of toxicity equivalent, GC/MS is used to separate and quantify 17 kinds of toxic isomers as in the conventional method. The GC/MS is of the quadruple focusing type, however, and this reduces the device cost at the initial stage and shortens the time for operators to acquire the skills of maintenance and operation. Though the quadruple focusing type is inferior to the double focusing type in sensitivity, the shortcoming is compensated for by massive specimen injection using a PTV (programmable temperature vaporizer). The result of a JIS (Japanese Industrial Standard) method and the result of this newly developed method are found to agree excellently with each other. This method is simple and efficient, suitable for use in the analysis of small incinerator flue gas. (NEDO)

    The general analysis/assessment method of a fossil fuel cycle was studied. Seven kinds of power generation plants such as LNG cycle and coal cycle ones, and four kinds of transport and treatment systems of recovered CO2 such as ocean and underground systems were studied as case studies on life cycle analysis. As data necessary for life cycle analysis, the database was constructed which stores the facilities and operational energy required for a total energy system from mining of fossil fuel to treatment of recovered CO2, and the quantity of environmental waste such as CO2 emission. As a result, the decrease rate of energy balance defined as ratio of input energy to power plant output was estimated to be 14-43% and 20-60% in LNG cycle and coal cycle, respectively. Even if the recovery rate of CO2 in power plants reached 80-90%, reduction of total CO2 emission was limited to only 20-40% because of CO2 emission during mining, liquefaction and transport of fuel. 168 refs., 48 figs., 102 tabs.

    Carbon emissions which would cause global warming were agreed to be constrained at COP3 in Kyoto. In addition, carton emission permits trading was also approved to be introduced. The emission permits trading is expected to achieve efficient carbon emission reduction, equalizing the marginal costs of the emission reduction for the participating countries. In other words, the permits trading allows participants to reduce emissions where it is least expensive to do so. However, the inadequate introduction of the trading systems may impose unfairly greater burden on some countries, and therefore careful evaluation of the system would be indispensable for its implementation. In this paper, we attempt to analyze the emission permits trading. using the theory of cooperative games with a global energy model of optimization type. We assumed that seven world regions as players participate the permits trading system under the condition of the emission reduction target presented at COP3 and so on, and show the nucleolus of the grand coalition games, and the computational results of primary energy supplies and CO2 shadow prices. The insights of this research indicate that in order to stabilize the grand coalition, a noticeable amount of additional transfer of money would be needed besides the payments associated with the emission permits trading. 10 refs., 7 figs., 5 tabs.

    This study is done for the purpose of numerically analyzing how customers react to make their choice between quality and price, as well as to evaluating the marketability of the new electric service differentiated by quality, on the assumption that electric utility is capable of providing the multi-product of the service with various combinations instead of the conventional single product between price and quality. An analysis was made for the customers like the large-scale computer users those who attach importance to quality. As for the method of the analysis, the choice (the introduction of emergency power source or uninterruptible power system) which have been actually done by the customers for the following two conditions, were used as the model of the analysis: The one was the standard of the requirements for the quality of electric power, of which requirements were composed of the two factors, such as the reliability on power supply and momentary voltage drop; The other was the cost (purchased power price plus investment by consumers for back-up power system) necessary to maintain the quality. Consequently, it was found that in order to heighten the competitiveness for the competition in electricity market, electric utility had to establish their service rate corresponding to the load, as well as that the quality was a important strategic factor for them. 30 refs., 10 figs., 9 tabs.

    An objective evaluation from a third party was conducted on the purpose, plan, execution method, achievement, etc. of a project 'The devilment of the catalyst surface high accuracy quantitative analysis technology using electron spectroscopy.' The purpose of the project is to make the relationing possible between the analytical results of the catalyst surface and the catalyst performance which has been so far difficult by heightening the accuracy of the catalyst quantitative surface analytical accuracy using the electron spectroscopy. The purpose and significance are judged to be worth a lot. This project is an industry/university/government joint project between the two countries. The project is excellent both in connection among research institutes and leadership of chief researchers, and it is judged that the joint research system fully functioned. The term of the project was shortened from 3 years in the first plan to 2 years, and therefore, the study was finished only on silicon oxide and organic thin films. However, it was determined that the study results are to be run in the magazine 'Surface and Interface Analysis,' which indicates that the achievement was judged to be very worth in the academic viewpoint.

    Trends toward power market deregulation were investigated in Japan and 16 other countries, and various deregulation models were examined and evaluated for their merits and demerits. There are four basic models, that is, franchise bidding model, competitive bidding in power generation model, wholesale wheeling or retail wheeling model, and mandatory pool or voluntary pool model. Power market deregulation has been a global tendency since the second half of the 1970s, with various models adopted by different countries. Out of the above-said models, it is the retail wheeling model and pool models (open access models) that allow the final customer to select power suppliers, and the number of countries adopting these models is increasing. The said models are characterized in that the disintegration of the vertical transmission-distribution integration (separation of distribution service and retail supply service) and the liberation of the retail market are simultaneously accomplished. The pool models, in particular, are enjoying favor because conditions for fair competition have already been prepared and because it is believed high in efficiency. In Japan and France, where importance is attached to atomic power generation, the competitive bidding model is adopted as a means to harmonize the introduction of competition into the source development and power generation sectors. 7 refs., 4 tabs.

    The effect of activated carbon (AC) on biodegradation of organic micropollutants in water was investigated, using fenitrothion, phenol and aniline as the model compounds, activated sludges cultured in a mixed solution of glucose, peptone and aniline, and Rhodotorula glutinis isolated as the phenol-degradation bacterium. The following conclusions are obtained by analyzing the corrected degradation curves derived from the adsorption equilibrium relationships, oxygen consumption characteristics and observed degradation curves. Biodegradation of each compound is accelerated in the presence of AC. Non-biological degradation of fenitrothion is also accelerated in the presence of AC, its effect being more noted in biodegradation and increasing as AC quantity increases. Phenol is biodegraded by different mechanisms, depending on its initial concentration. The maximum oxygen consumption rate during the biodegradation of phenol increases in the presence of AC, conceivably resulting from enhanced bacterial activities. 5 refs., 6 figs., 4 tabs.

    Furfural is produced in the distillation stage of low-class distilled spirit manufacturing and badly influences the quality of products. The removal of minute amount of furfural in an ethanol aqueous solution was thus investigated by an Oldershow-type batch-rectifying column consisting of ten plates. Furfural of 50 ppm was added to an ethanol aqueous solution of 6.6 mole% as raw materials. If the ethanol concentration in the upper distillation plates is set high, furfural is forecast to be concentrated in the intermediate plate. In an experiment, side-cut was carried out at this plate. If side-cut is performed at the seventh-plate tray from the top, the total side-cut rate is 12%. In this case, 77% of furfural is removed. The side-cut rate of ethanol at that time was 11%. Moreover, 85% of furfural was removed when ethanol with high concentration was extracted from the top under total reflux conditions and when side-cut was carried out. Only 9% of ethanol was distilled in this case. It was confirmed that furfural can be separated using a multi-plate batch-distilling column. 2 refs., 4 figs., 1 tab.

    To obtain the basic data to develop instruments for diagnosis of atherosclerosis and to elucidate the mechanisms of atherogenesis by focusing on the autofluorescence of blood and vascular walls of atherosclerotic animal models and human patients. We have performed experiments to examine the relationships between autofluorescence of blood and vascular walls of guinea pig atherosclerotic model and human patients and obtained the following results. 1. The autofluorescence from human atherosclerotic aorta included the components with longer wave length than normal aorta, suggesting that diagnosis of atherosclerotic aortic walls will be possible using spectroscopic analysis through glass fiber catheter into vascular system. Further studies should be needed to the quantitative diagnosis. 2. The autofluorescence from blood plasma of human atherosclerotic patients has showed that the peak wave length was shorter than that of normal plasma. This phenomenon was mainly caused by the oxidization of plasma, especially lipoproteins, LDL and HDL. 3. Atherosclerotic model of the guinea pigs was quite similar to human atherosclerosis at the points of cholesterol levels and localization of lipid deposit to arterial walls, and showed to be useful for the studies of atherosclerosis.

    Molibdophosphoric acid (PMo) reacts with malachite green (MG{sup +}) to form a colored ion associate (MG{sup +}- PMo) in an acidic solution according to the formula : HMG{sup 2+}+H{sub 3}PMo{sub 12}O{sub 40}{yields}(MG{sup +})H{sub 2}PMo{sub 12}O{sub 40}+2H{sup +}. A protonated form HMG{sup 2+} is yellow (the absorption mximum at 446 nm), whereas the ion associate MG{sup +} is blue green (the absorption maximum at 650 nm). MG{sup +} is found to accelerate the formation of PMo. Water-miscible organic solvents such as methanol,ethanol and propanol also accelerate the formation of PMo as well as the formation of MG sup + - PMo. Some anionic surfactants decelerate the reaction, however, contribute to the suppression of the baseline drift in a flow injection analysis (FIA). By the use of the proposed reaction accelerator and surfactant. a highly sensitive FIA system is established for,orthophosphate up to the range of several ppb. 16 figs.. 11 refs.

    Element technology is studied to realize a reflective-type, full-color, and high-resolution liquid crystal display for super-low power consumption data display. As to the functional compound microstructure formation technology, a 4-inch panel was trially fabricated using two-layer guest-host liquid crystal technology to achieve the desired display performance by control of molecular orientation. Further, holographic PDLC elements were favorably test-fabricated. A ferroelectric PZT thin layer was formed by forming layer at low temperature at which a glass substrate can be used. Optical interference/optical dispersion type optical control materials were studied by liquid crystal/polymer composition. Also studied were super-pure/super-reliable liquid crystal compound/liquid crystal composite systems and super-anisotropic liquid crystal compound by modeling ionic impurities and liquid crystal molecular interaction. In relation to the control technology of optical reflection characteristics, effects of liquid crystal molecular structures (derivative effect and copolymer composition) on orientation were elucidated. As to the technology to form multi-dimensional anisotropic structures, efforts were made for the heightening of formation technology of simple RGB (red, green, blue) directional reflection layers using acrylate materials. The paper also outlined the comprehensive survey. (NEDO)

    The paper developed an analysis method of the energy supply/demand structure of city and compared the conventional city and a city considering energy conservation. An energy supply/demand flow chart was newly proposed. From this flow chart, `energy sustainability ratios` was proposed as a new index for comprehensively evaluating two elements of the energy conservation by load reduction and heightening of energy conversion rates and the utilization of waste heat and renewable energy. A method for analysis of the energy supply/demand structure of city was developed including daily supply/demand patterns in the area where individual equipment in every residence/building correspond to the energy supply and the area where centralized energy systems such as district energy supply correspond it. From the developed analysis method, analysis was made of a newly developed city with a 0.6 million population in terms of the conventional city and energy conservation city, to clarify the present energy supply/demand structure of city and to express it in an energy flow chart. At the same time, validity of the analysis method and evaluation indexes were confirmed by comparing the conventional city and energy conservation city. 15 refs, 27 figs., 17 tabs.

    Power supply services, city gas supply services, water supply and drainage services, roads, and buildings were treated as urban infrastructures so as to grasp the resources and CO2 emission consumed in their life cycle. Moreover, the consumption of resources for supporting one person and the emission of CO2 were analyzed to clarify an important point for resource saving and environmental load reduction. The resources used and CO2 emitted for each urban infrastructure were calculated with Kanto districts as a target. For the annual material weight a person, buildings are about 1,200 kg, roads are about 560 kg, and city gas is about 170 kg. Water supply and drainage is about 68 kg, and electric power is about 57 kg. For the annual CO2 emission a person, buildings are about 120 kg-C, roads are about 13 kg-C, and electric power is about 6.6 kg-C. City gas is about 5.3 kg-C, and water supply and drainage is about 4.4 kg-C. In the material weight for each resource, gravel, crushed stone, concrete, and asphalt concrete have a high consumption rate. In CO2 emission, iron, concrete, and gas oil form a high rate. 21 refs., 26 figs., 2 tabs.

    For analytical evaluation of effects of environmental protection measures, energy conservation measures, new energy promotion measures, etc., a very-long term energy supply/demand model was developed and used for a simulational study. The model is composed of the models of macro economics, secondary energy prices, new energy introduction, and energy supply/demand. The feature is that the amount of new energy introduction is measuringly analyzed based on the cost and market scale, and integratedly estimated in a frame of energy supply/demand of the whole Japan. As a result of the simulation, energy source as of 2030 is composed of coal (17%), oil (44%) and nuclear power (15%) in the case of the economic growth as viewed optimistically. Contrarily, in the case of it as viewed pesimistically, energy source is composed of coal (11%), oil (40%) and nuclear power (22%). CO2 emission is -12.4% in the case of the new energy promotion than in the standard case. 7 refs., 79 figs., 107 tabs.

    For the econometric analysis of petroleum substitution energy, a domestic econometric model was developed which can concretely and econometrically grasp and analyze effects of measures taken for environmental policies, energy conservation, promotion of new energy, etc. The model was made so synthetic as to catch a relationship between energy supply/demand and changes of econosocial structures in economic growth, industrial structure, life style, etc. which are extremely important elements for catching future energy demand. The model is composed of a secondary energy price model, a new energy introduction model, and an energy supply/demand model. As case parameters, selected were the price of crude oil, introduction of new energy, GDP and energy conservation, and the following cases were assumed: standard case, high price energy case, new energy introduction promotion case, low economic growth case, energy conservation case, and low energy demand case. The results of simulating each of these cases were indicated. 91 figs., 110 tabs.

    Full Text Available A nonlinear robust control-system design framework predicated on a hierarchical switching controller architecture parameterized over a set of moving nominal system equilibria is developed. Specifically, using equilibria-dependent Lyapunov functions, a hierarchical nonlinear robust control strategy is developed that robustly stabilizes a given nonlinear system over a prescribed range of system uncertainty by robustly stabilizing a collection of nonlinear controlled uncertain subsystems. The robust switching nonlinear controller architecture is designed based on a generalized (lower semicontinuous Lyapunov function obtained by minimizing a potential function over a given switching set induced by the parameterized nominal system equilibria. The proposed framework robustly stabilizes a compact positively invariant set of a given nonlinear uncertain dynamical system with structured parametric uncertainty. Finally, the efficacy of the proposed approach is demonstrated on a jet engine propulsion control problem with uncertain pressure-flow map data.

    For contributing to the formulation of technology development programs, an analysis is conducted based on the concept of value web into which the economic spread effect is incorporated. As information technology plays an important role in the fields of automobiles and chemical materials, there are various fields the research and development efforts exerted in which are common to many others. As to what additional values are created when such separately developed technologies cross each other, a discussion is conducted using techniques of industry-oriented analyses. Findings obtained are mentioned below. When the numbers of essays relative to the respective industries are compared, it is found that 63% of the total number of biotechnological essays fall on agriculture, the drug industry, and the food industry. On the other hand, when it comes to the produce, related industries larger in marketing scale is more strongly influenced by the spread effect. The spread effect of biotechnology is distinguished in the drug industry, and that of information/communication technology in the information industry, electric and electronic industries, and in the semiconductor industry.

    In order to clarify a humification process in the early stage of coalification, the nitrogen functionality of prepared glucose-glycine condensate was studied experimentally. In experiment, the condensate was prepared by heating the mixture of glucose, glycine and water in a autoclave at 130{degree}C for 50 hours, and furthermore heating the produced solid material in water at 300{degree}C. After the condensate was hydrocracked, the fraction, condensate and hydrocracking residue were analyzed by elementary analyzer, {sup 13}C-NMR, XPS, FT-IR, capillary GC-FID/NPD and GC-MS. As a result, the glucose-glycine condensate could be arranged on the basis of three types of nitrogen such as pyridine, pyrrole and quaternary amine type. Pyridine type nitrogen increased, while quaternary amine type one decreased with an increase in heating treatment temperature. Rich pyrrole type nitrogen and poor pyridine type one were found in light nitrogen compounds in hydrocracked products. 2 refs., 4 figs., 2 tabs.

    This report summarizes the fiscal 1999 research result on simulation analysis on petroleum substituting energy. The simulation model for analyzing social and energy supply and demand structures comprehensively was established by improving the China and Korea models developed in fiscal 1998 through a use of input-output tables. In simulation of the China model, the reference case showed that a primary energy demand in 2030 reaches 3.3 times as much as that in 1997 (2.9 times in CO{sub 2}), resulting in serious energy and environment problems. Reduction of primary energy and CO{sub 2} is possible by promotion of energy saving and introduction of a carbon tax. In simulation of the Korea model, the reference case showed that CO{sub 2} emission in 2030 reaches 2.2 times as much as that in 1997, showing an annual increase rate of 2.4%. The annual increase rate can be reduced by introducing a carbon tax. The simulation model for automobile energy was also established for major countries in Asia. Automobile energy consumption increases with diffusion of automobiles until 2030 gradually. In particular, the consumption in China reaches that in Japan in 2010. (NEDO)

    In order to study coal production processes, an estimation study was carried out on coal originating materials by using biomaker analysis. Test samples are original coals collected directly from a mine in Hokkaido (not having been subjected cleaning). Mixing and solvent extraction were performed after pulverization, and then tests were given on saturated hydrocarbon components divided by using a silicagel column chromatograph for the present study. It can be known from n-alkane distribution in the coal that low molecular alkane increases with increasing degree of coalification. Artificial coal made by wet-heating Metasequoia leaves contains only little n-alkane. Diterpenoid compound exists in the Taiheiyo and Akabira coals. Tetra-cyclic diterpernoid is contained abundantly in subtropical coniferous trees, serving as a parameter for warm environment. The compound is contained also in the Fushun coal, but not in Indonesian coals. Hopanoid constitution shows very high similarity, but H/C atomic ratio may vary largely even if the coalification is at the same degree. This is likely to be caused from difference in originating materials. Hopanoids are bacteria attributed substances, whose activities are not affected by the originating materials. 2 figs., 1 tab.

    Electric utilities positively wrestle now with business diversification such as telecomunication, thermal supplying, urban planning to intensify the administrative foundation under relaxation for regulations. These businesses are yet small scale ones but are supposed to enlarge to the scale equivalent to the main business for a long period. Since the electric industry is a public utility enterprise and has fewer experiences to develop concrete diversifying strategy, this research was proceeded to determine the directions of diversification by analyzing management data or making hearing for well-diversified corporations such as fiber industry, private railway industry, and leasing industry. It was found from this study that diversification would have the possibility of plus for multiple managerial indeces such as profitability, growability and stability and that the diversification would be developed by using effectively the managerial resources. Then, the conditions on which electric utilities must consider when they enter into new businesses were arranged on the basis of this survey. 46 refs., 14 figs., 9 tabs.

    With economy growing at a fast pace in the Asia-Pacific region in recent years, demand for energy is sharply increasing in various industries, and the demand is expected to continue to grow. It is afraid that the trend may extend to other developing regions such as East Europe. It is, and will remain to be, important to prevent warming, assure sustained economic development, and secure stable supply of energy on the global scale. The survey in this report aims to grasp the trends of energy efficiency improvement in Asia-Pacific nations, in other developing nations, and in developed nations as well, to ultimately serve the best interests of Japan. For the achievement of the goal, Japan's attitude toward energy conservation promotion activities is expressed at international conferences on energy conservation promotion such as those of APEC (Asia-Pacific Economic Cooperation Conference) in the Asia-Pacific region and of environmental/energy-saving conferences of IEA (International Energy Agency) in Europe and America. On these occasions, information is collected and overseas technical literature is obtained thanks to the established coordination with United Nations-affiliated organizations and key persons in various countries. Data and information thus acquired are utilized for the investigation and analysis of energy conservation technologies and policies adopted and diffused in the respective nations involved. Using them, promotion of energy conservation policies in the Asia-Pacific region and establishment of environmental friendliness are also investigated. (NEDO)

    Study is under way for a more accurate solar radiation quantity prediction for the enhancement of solar energy utilization efficiency. Utilizing the technique of roughly estimating the day`s clearness index from forecast weather, the forecast weather (constituted of weather conditions such as `clear,` `cloudy,` etc., and adverbs or adjectives such as `afterward,` `temporary,` and `intermittent`) has been quantified relative to the clearness index. This index is named the `weather index` for the purpose of this article. The error high in rate in the weather index relates to cloudy days, which means a weather index falling in 0.2-0.5. It has also been found that there is a high correlation between the clearness index and the north-south wind direction component. A multiple regression analysis has been carried out, under the circumstances, for the estimation of clearness index from the maximum temperature and the north-south wind direction component. As compared with estimation of the clearness index on the basis only of the weather index, estimation using the weather index and maximum temperature achieves a 3% improvement throughout the year. It has also been learned that estimation by use of the weather index and north-south wind direction component enables a 2% improvement for summer and a 5% or higher improvement for winter. 2 refs., 6 figs., 4 tabs.

    Technological change is a major driving force for long-run economic growth. New theories on growth have stressed the importance of innovative and adaptive capacity of firms in order to fully reap the benefits of research and development (R and D) within the firms as well as those spilled-over from other firms and abroad. This report empirically investigates the relationship between R&D and productivity as well as that between productivity and industrial competitiveness for the G-5 countries (Japan, the US, (West) Germany, France and the UK). To do so, we have constructed comparable data on R and D capital stock (so-called 'knowledge capital'), the level and growth rates of total factor productivity (TFP), and the revealed comparative advantage (RCA) index for 22 manufacturing industries in each G-5 country. The major results are summarized as follows. First, the volume of knowledge capital for Japan is still far smaller than that of the US (40% for total manufacturing in 1995). Second, there is no clear tendency of TFP convergence to the US level for each country after 1980 and its level for Japan is about 70% of the US in 1993. In addition, the TFP gap between Japan and the US has recently widened for high-tech sector. Third, the estimated elasticities of TFP with respect to the R&D stock for manufacturing sector during the mid-1970s and the early 1990s are 0.07 for Japan and 0.21 for the US on average, with deteriorating R and D potency in Japanese manufacturing. For high-technology industries, they are much larger with the estimates of 0.45 for Japan and 0.86 for the US on average, whereas for Japan the R&D performance becomes worse during the last decade. Fourth, we found that international competitiveness in industries depends not only on TFP and exchange rate fluctuations, but also on various non-price factors such as product quality, marketing ability, and product market segmentation.

    A proposal is made on a method to analyze a slope disaster in detail from a viewpoint of ''where the disaster occurred'' (to analyze in a line pattern the apertures of a collapse and main scarps in a land slide). Methodological emphasis was placed on superimposing aerial photograph images taken before and after a disaster over imaged information on factors based on land conditions including topographical characteristics. Applicability of this method was discussed using a landslide location in Niigata Prefecture as an example. This paper describes the result of tb discussion by the following items: Imaging the aerial photographs and correcting their geometrical distortion; extracting items of line-pattern information from the aerial photographs and classifying the land coverage; and analyzing factors of causing the landslide using an image superimposing process. The papers also mentioned a view that this method may be applied effectively on disasters occurring on ground surface. 11 refs., 8 figs., 2 tabs.

    For development of production technologies suitable for environment, safety and advanced information-oriented society by improving the flexibility of production lines, some new measurement technologies were researched. Problem solution was attempted by combining the in-situ multi-dimensional measurement technology capable of easily obtaining various 3-D information with the non-contact photon measurement technology superior in operability and sensitivity under any environment conditions. This solution requires a compact radiation source with higher brightness and wider spectral range, and a high-sensitive detector. The technology concentrating photon onto minute regions, high-efficiency transmission, and control technology of photon wave front are also necessary. Development and international standardization of a common interface is unavoidable. In addition, its network is essential for advanced use of multimedia,. In the future, the comfortable life surrounded by advanced products and multimedia, comfortable social environment, safety and resource saving will be achieved by this technology. 94 refs., 75 figs., 15 tabs.

    The material balance of carbonization products (wood-gas, wood-vinegar, wood-tar and charcoal) prepared from the sapwood and the heartwood of Sugi (Cryptomeria japonica D. Don) at various temperatures was determined. The evolution of both carbon monoxide and carbon dioxide mainly occurred at the carbonization temperature below 600 degree C and that of hydrogen and methane at 600-800 degree C. Total yield of the wood-vinegar and the wood-tar was almost constant at 500-800 degree C. On the other hand, the yield of the charcoal decreased because of the evolution of the wood gas with an increase in carbonization temperature. The wood-vinegars prepared at the temperature over 400 degree C were found to consist of carboxylic acids such as acetic acid and propionic acid, methanol, acetone, furans, alkylphenols, guaiacols, cyclotene and maltol by capillary gas chromatography. Since the constituent varieties and contents of the wood-vinegars prepared at both 400 degree C and 800 degree C were very similar each other, the wood-vinegar of Sugi wood chiefly produced below 400 degree C. FT-IR spectra of the charcoals showed the generation of carbonyl and olefin groups at 300-400 degree C and then the formation of aromatic rings along with the disappearance of carbonyl groups over 600 degree C. The production of radical species in the charcoals carbonized at 300-600 degree C was observed by ESR, on the contrary, the charcoals carbonized over 700 degree C were inactive. The specific surface area and the pore volume of the charcoal of Sugi sapwood increased with an increase in carbonization temperature. The pH of charcoal-dispersed aqueous solution increased with an increase in carbonization temperature. The high adsorptive activity of the charcoal carbonized at 400 degree C for ammonia gas and that at 800 degree C for hydrogen sulfide gas seemed to be dependent on acidic and basic properties of the charcoals, respectively.

In the previous, although there was a measuring method of mental stress by RSA, a issue arise such as reliability of analysis, because driver`s heart rate affect by respiration and muscle motion as well. We have established a method to measure mental stress by fractal dimension. And tried it is the proving ground and public road driving. We have confident that it is more reliable than RSA to quantify driver`s mental stress and fatigue. 9 refs., 9 figs., 1 tab.

    Looking for effective policy on petroleum substituting energy, measuring models were made for analyzing relations between changes in social structure and energy supply/demand structure. Through the simulation using these models, effects of difference in energy policy on economy and energy supply/demand were studied. Countries for survey were Thailand, the Philippines, Indonesia, Malaysia, China and Korea. The measuring model is composed of the macroeconomic model and the energy supply/demand model. In the case of Korea, the interindustry-relations model was added. Using the macroeconomic model, asked were fluctuations in various economic activities/industrial structure/price/trade balance such as GDP and crude steel production by inputting overseas indices, population indices and financial indices such as the world trade, crude oil price and exchange rates. In FY 2000, for ASEAN countries, data were collected for analysis of relations between changes in economical/social structure and energy supply/demand structure. Using the pilot model constructed, the simulation was made on the standard case. (NEDO)

    Evaluation is one of many fields where "systems thinking" is popular and is said to hold great promise. However, there is disagreement about what constitutes systems thinking. Its meaning is ambiguous, and systems scholars have made diverse and divergent attempts to describe it. Alternative origins include: von Bertalanffy, Aristotle, Lao Tsu or multiple aperiodic "waves." Some scholars describe it as synonymous with systems sciences (i.e., nonlinear dynamics, complexity, chaos). Others view it as taxonomy-a laundry list of systems approaches. Within so much noise, it is often difficult for evaluators to find the systems thinking signal. Recent work in systems thinking describes it as an emergent property of four simple conceptual patterns (rules). For an evaluator to become a "systems thinker", he or she need not spend years learning many methods or nonlinear sciences. Instead, with some practice, one can learn to apply these four simple rules to existing evaluation knowledge with transformative results.

    The paper presents a view of systems integration, from an ergonomics/human factors perspective, emphasising the process of systems integration as is carried out by humans. The first section discusses some of the fundamental issues in systems integration, such as the significance of systems boundaries, systems lifecycle and systems entropy, issues arising from complexity, the implications of systems immortality, and so on. The next section outlines various generic processes for executing systems integration, to act as guides for practitioners. These address both the design of the system to be integrated and the preparation of the wider system in which the integration will occur. Then the next section outlines some of the human-specific issues that would need to be addressed in such processes; for example, indeterminacy and incompleteness, the prediction of human reliability, workload issues, extended situation awareness, and knowledge lifecycle management. For all of these, suggestions and further readings are proposed. Finally, the conclusions section reiterates in condensed form the major issues arising from the above.

Artificial neural networks are not only capable of learning how to classify patterns, such images or sequence of events, but they can also effectively model complex nonlinear systems. Their ability to classify sequences of events is probably more popular in industrial applications where there is an inherent need to model nonlinear system

    2008-08-19

    Darwin's 19th century evolutionary theory of descent with modification through natural selection opened up a multidimensional and integrative conceptual space for biology. We explore three dimensions of this space: explanatory pattern, levels of selection, and degree of difference among units of the same type. Each dimension is defined by a respective pair of poles: law and narrative explanation, organismic and hierarchical selection, and variational and essentialist thinking. As a consequence of conceptual debates in the 20th century biological sciences, the poles of each pair came to be seen as mutually exclusive opposites. A significant amount of 21st century research focuses on systems (e.g., genomic, cellular, organismic, and ecological/global). Systemic Darwinism is emerging in this context. It follows a "compositional paradigm" according to which complex systems and their hierarchical networks of parts are the focus of biological investigation. Through the investigation of systems, Systemic Darwinism promises to reintegrate each dimension of Darwin's original logical space. Moreover, this ideally and potentially unified theory of biological ontology coordinates and integrates a plurality of mathematical biological theories (e.g., self-organization/structure, cladistics/history, and evolutionary genetics/function). Integrative Systemic Darwinism requires communal articulation from a plurality of perspectives. Although it is more general than these, it draws on previous advances in Systems Theory, Systems Biology, and Hierarchy Theory. Systemic Darwinism would greatly further bioengineering research and would provide a significantly deeper and more critical understanding of biological reality.

    As a part of the research and development regarding characterisation of deep geological environment, the GEOMASS (GEOLOGICAL MODELLING ANALYSIS AND SIMULATION SOFTWARE) system has been developed by the Japan Atomic Energy Agency in order to carry out geological and hydrogeological modelling and groundwater flow simulation and so on. The GEOMASS system integrates a commercial geological interpretation system (EarthVision), which is used for geological modelling and visualisation, with a proprietary code for groundwater flow (FracAffinity). This integrated system allows users to make rapid improvement of models as data increases. Also, it is possible to perform more realistic groundwater flow simulation due to the capability of modelling the rock mass as a continuum with discrete hydro-structural features in the rock mass. This paper consists of 'Overview of GEOMASS system', FracAffinity Theoretical Background' and 'FracAffinity User Guide' and is edited as a GEOMASS system manual. 'Overview of GEOMASS system' describes the outline of this system. 'FracAffinity Theoretical Background' describes the information of technical background of FracAffinity software. FracAffinity User Guide' describes the structure of the FracAffinity input files, the usage of FracAffinity Interface and flow-solver. Updating of the FracAffinity has been continued as needed and FracAffinity version3.3 is the latest version at present (July 2008). (author)

    A reactive system comprises networks of computing components, achieving their goals through interaction among themselves and their environment. Thus even relatively small systems may exhibit unexpectedly complex behaviours. As moreover reactive systems are often used in safety critical systems......, the need for mathematically based formal methodology is increasingly important. There are many books that look at particular methodologies for such systems. This book offers a more balanced introduction for graduate students and describes the various approaches, their strengths and weaknesses, and when...... they are best used. Milner's CCS and its operational semantics are introduced, together with the notions of behavioural equivalences based on bisimulation techniques and with recursive extensions of Hennessy-Milner logic. In the second part of the book, the presented theories are extended to take timing issues...

    1992-03-01

    The CASDAC (Containment And Surveillance Data Authenticated Communication) system has been developed by JAERI for nuclear safeguards and physical protection of nuclear material. This system was designed and constructed as an upgraded RECOVER system, design concept of which was based on the original RECOVER system and also the TRANSEAVER system. Both of them were developed several years ago as a remote monitoring system for continual verification of security and safeguards status of nuclear material. The system consists of two subsystems, one of them is a Grand Command Center (GCC) subsystem and the other is a facility subsystem. Communication between the two subsystems is controlled through the international telephone line network. Therefore all communication data are encrypted to prevent access by an unauthorized person who may intend to make a falsification, or tapping. The facility subsystem has an appropriate measure that ensure data security and reliable operation under unattended mode of operator. The software of this system is designed so as to be easily used in other different types of computers. This report describes the outline of the CASDAC system and the results of its performance test. This work has been carried out in the framework of Japan Support Programme for Agency Safeguards (JASPAS) as a project, JA-1. (author)

    This monograph presents a systematic analysis of bubble system mathematics, using the mechanics of two-phase systems in non-equilibrium as the scope of analysis. The author introduces the thermodynamic foundations of bubble systems, ranging from the fundamental starting points to current research challenges. This book addresses a range of topics, including description methods of multi-phase systems, boundary and initial conditions as well as coupling requirements at the phase boundary. Moreover, it presents a detailed study of the basic problems of bubble dynamics in a liquid mass: growth (dynamically and thermally controlled), collapse, bubble pulsations, bubble rise and breakup. Special emphasis is placed on bubble dynamics in turbulent flows. The analysis results are used to write integral equations governing the rate of vapor generation (condensation) in non-equilibrium flows, thus creating a basis for solving a number of practical problems. This book is the first to present a comprehensive theory of boil...

    Full Text Available Two strategies towards the realization of nanotechnology have been presented, i.e., top-down and bottom up. The former one is mainly based on nanofabrication and includes technologies such as nano-lithography, nano-imprint, and etching. Presently, they are still 2D fabrication processes with low resolution. The later one is an assembly-based technique. At present, it includes such items as self-assembly, dip-pen lithography, and directed self-assembly. These techniques can generate regular nano patterns in large scales. To fabricate 3D complex nano devices there are still no effective ways by so far. Here we show our effort on the development of a nano laboratory, a prototype nanomanufacturing system, based on nanorobotic manipulations. In which, we take a hybrid strategy as shown in Fig. 1. In this system, nano fabrication and nano assembly can be performed in an arbitrary order to construct nano building blocks and finally nano devices. The most important feature in this system is that the products can be fed back into the system to shrink the system part by part leading to nanorobots. Property characterization can be performed in each intermediate process. Due to the nanorobotic manipulation system, dynamic measurement can be performed rather than conventional static observations.

  10. Fiscal system analysis - contractual systems

    Production sharing contracts are one of the most popular forms of contractual system used in petroleum agreements around the world, but the manner in which the fiscal terms and contract parameters impact system measures is complicated and not well understood. The purpose of this paper is to quantify the influence of private and market uncertainty in contractual fiscal systems. A meta-modelling approach is employed that couples the results of a simulation model with regression analysis to construct numerical functionals that quantify the fiscal regime. Relationships are derived that specify how the present value, rate of return, and take statistics vary as a function of the system parameters. The deepwater Girassol field development in Angola is taken as a case study. (author)

    1990-01-01

    The represent invention concerns a reactor system with improved water injection means to a pressure vessel of a BWR type reactor. A steam pump is connected to a heat removing system pipeline, a high pressure water injection system pipeline and a low pressure water injection system pipeline for injecting water into the pressure vessel. A pump actuation pipeline is disposed being branched from a main steam pump or a steam relieaf pipeline system, through which steams are supplied to actuate the steam pump and supply cooling water into the pressure vessel thereby cooling the reactor core. The steam pump converts the heat energy into the kinetic energy and elevates the pressure of water to a level higher than the pressure of the steams supplied by way of a pressure-elevating diffuser. Cooling water can be supplied to the pressure vessel by the pressure elevation. This can surely inject cooling water into the pressure vessel upon loss of coolant accident or in a case if reactor scram is necessary, without using an additional power source. (I.N.)

    In spite of the remarkable safety record of the nuclear industry as a whole, recent public concern over the potential impact of the industry's accelerated growth has prompted ERDA to expand its emergency response procedures. The Atmospheric Release Advisory Capability, ARAC, is a computer communications system designed to enhance the existing emergency response capability of ERDA nuclear facilities. ARAC will add at least two new functions to this capability: centralized, real-time data acquisition and storage, and simulation of the long range atmospheric transport of hazardous materials. To perform these functions, ARAC employs four major sub-systems or facilities: the site facility, the central facility, the global weather center and the regional model. The system has been under development for the past two years at the Lawrence Livermore Laboratory of the University of California

Spin-systems are well-defined models, for which, in special cases, exact properties may be derived. These special cases are for the greater part, one- dimensional and restricted in their applicability, but they may give insight into general properties that also exist in higher dimension. This work pays special attention to qualitative differences between spin lattices of different dimensions. It also replaces the traditional picture of an (ordered) antiferromagnetic state of a Heisenberg sy

    Demand side management through a pricing mechanism, that is the indirect load control was experimented to analyze the pricing effect. When power consumption in indirect load control groups is compared between peak time band in weekdays in summer and off-the-peak time band, the power is less consumed when price gap is set than in a uniform charge time. When more number of persons is in home in daytime, room cooling is used in daytime including the peak band to adjust the demand. The substitution elasticity in price between demands in the peak time band and the off-the-peak time band is from about 0.06 to 0.07, which cannot be ignored. If the peak price is increased by four times, the demand in the peak band can be reduced by about 0.15 kW (when average power demand per household is assumed 0.75 kW). For room cooling devices, the first device is often installed in a living room and the second and further units in individual rooms such as bed rooms. The more the number of device, the higher the possibility that the use time band is outside the peak time band. This indirect load control experiment is a field test related to the peak-activated pricing for small power users, by which the users` behavior against the pricing effect was identified quantitatively. 5 refs., 1 fig., 8 tabs.

The mutual reliance relationship among the project partners has been built gradually in such ways as Shell has built an agricultural vocational school inviting professors specialized in agriculture from England. Mitsubishi has created a large-scale cattle breeding business and produced beef cattles under the severe tropical environment, with an unfortunate result that the production cost did not balance with the market price. Recently, three Japanese agricultural engineers have succeeded at last producing tomatoes, cucumbers and lettuces through endeavors of vegetable production by means of hydroponic processes. The Brunei Goverment is also planning to cultivate fish and shells. Meanwhile the voices from the working site stress strongly that the operation has been continued with the safety-first concept at all times.

    This project aims at development of the high-accuracy quantitative analysis technique by electron spectroscopy for surface analysis of catalysts and semiconductors. Since conventional analysis technique using an energy-fixed X-ray excitation source is inadequate to obtain satisfactory surface sensitivity and quantitative accuracy for catalysts, for development of the titled technique, this project makes experiment using energy-variable synchrotron radiation to modify the parameter on motion of low-speed electrons in solids which is obtained by Monte Carlo calculation. For establishment of the high-accuracy quantitative analysis technique of surface compositions of materials such as catalyst of which performance is dominated by utmost surface, the project studies the attenuation length of electrons in solids by electron spectroscopy using soft X-rays from synchrotron radiation. In this fiscal year, the project established the equipment and technique for high-accuracy quantitative analysis of the thickness and electron attenuation length of silicon oxide films on silicon wafers by electron spectroscopy.

    This project targets to make analysis of surface chemical phenomena of solid catalysts possible, and establish the basis of intelligent design for catalytic materials, through development of an advanced electron spectroscopy for surface analysis. In fiscal 1999, the research was promoted by using the diffraction grating and driving mechanism introduced in fiscal 1998, and by developing the measurement result on silicon oxide films by radiation beam photoelectron spectroscopy. The measurement technique was established by the optimized measurement process which can treat variable parameters as constant. The analysis result of measurement data in fiscal 1999 showed the dependence of an electron damping length in silicon oxide films on radiation photon energy. The energy dependence well agreed with a theoretically obtained inelastic mean free path of electrons qualitatively, while was smaller by nearly 30% than the latter quantitatively. Measurement was made on the damping length in oxidation-active Gd and Nd oxide films. In both cases of Si and Si oxide film substrates, oxidation of substrates or formation of silicate was observed.

    The survey on the reduction measures against greenhouse effect gases was carried out which was proposed by the IEA-GHG phase 3 program. In Japan, various low emission vehicles (LEV) such as electric, methanol and natural gas vehicles are under rapid development. Like France, cost reduction and preparation of fuel filling stations are urgently necessary for the diffusion of LEVs. In New Zealand, air pollution by automobiles is not essential. The Switzerland government is promoting the diffusion of compact electric vehicles, and inhibits the use of conventional automobiles in some tourist resorts. The California state is leading the world by prescribing the bold regulation for preventing the air from pollution. In particular, the state government put automobile manufacturers under an obligation to produce zero emission vehicles (ZEV, electric vehicle) by 2% of passenger cars and trucks from 1998 and to increase ZEVs up to 10% until 2010. This report also includes two papers concerned, `Forestry management for sustainable development` and `Tropical forestry action plan after five years.` 142 refs., 19 figs., 23 tabs.

    Product evaluation has been investigated from a viewpoint of compatibility with human life by considering human being as the subject of life. This report describes the investigation results. Product evaluation is defined as evaluating products on a consumer-oriented viewpoint and informing consumers of the evaluation results. According to a questionnaire survey with regard to daily living products, products in the low degree of satisfaction in their usage were electric tooth brush, video camera, electric rice jar, vacuum cleaner, and electric iron. Contents of dissatisfaction with these products were classified by aspect, i.e., human aspect regarding human body/recognition, life aspect regarding functions of products and how to use them, and sensitivity aspect such as appearance of products. Thus, points at issue were clarified. As regards the human aspect, incompatibility between the size/form of products and human body/posture, and recognition psychological incompatibility such as difficulty in understanding function or operation of products were pointed out. Establishment of a method for measuring and evaluating the human`s body functions and the compatibility with products, and necessity of the acquisition of human`s body characteristic data and the consolidation positions are also described. 4 refs., 42 figs., 30 tabs.

    A d.c. bias current driven by the self-bias voltage which is conducted through the r.f.-powered glow discharge plasma varies the emission characteristics drastically, leading to improvement of the detection power in the optical emission spectrometry. By conducting the bias currents of 20-30 mA, the emission intensities of the atomic resonance lines were 10-20 times larger than those obtained with conventional r.t.- powered plasmas. The detection limits for determination of alloyed elements in the re-based binary alloy samples were estimated to be l.6 x 10{sup -3}% Cr for CrI 425.43nm, 7 x 10{sup -4}% Mn for MnI 403.10nm, 1.9>10{sup -3}% Cu for CuI 327.40nm, 1.1 x 10{sup -3}% Al for AlI 396.16nm, and 6.6 x 10{sup -3}% Ni for NiI 352.45 nm.

    This paper describes comprehensive evaluation and analysis mainly on the 51 items adopted in the high-performance industrial furnace introduction field tests. The development of a high-performance industrial furnace has completed the fundamental development research in fiscal 1998, and the possibility was verified on energy saving of more than 30% and reduction of NOx emission by 50% over that by conventional furnaces. Upon this fundamental achievement, the field test project has started as the comprehensive approach to developing the practically usable technologies for three years from fiscal 1998 until fiscal 2000, which is being promoted as a joint research project. According to the survey on the actual state in fiscal 1998, a little less than 20,000 industrial furnaces having combustion capacity of more than 500,000 Kcal/hr (excepting boilers) are being used. If these furnaces are converted into the high-performance industrial furnace, energy conservation of 210,000 x 10{sup 6} Mcal (converted to crude oil of 22.7 x 10{sup 6} kl/year) can be achieved from the maximum annual energy consumption of 700,000 x 10{sup 6} Mcal (converted to crude oil of 75.7 x 10{sup 6} kl/year). This conservation amount corresponds to about 12% of the final energy consumption in the whole Japanese industrial departments in fiscal 1996. It is expected that the performance of the full-size high-performance industrial furnace will be verified, and this technology will be promoted for wide proliferation. (NEDO)

    The project aims to prepare inter-industry relations tables and models for energy analysis for Asian countries and thereby to probe into relations between the industrial structure or the ultimate consumption structure and energy consumption. For the comprehension of energy consumption as broken by each industry, Asian nations' inter-industry relations tables and energy statistics are linked for the compilation of energy analysis oriented inter-industry relations tables, and the resultant tables are used for the metric analysis of industrial structures and energy consumption structures in these countries. The tables prepared this time are 1985 tables for Korea, Indonesia, Thailand, and the Philippines and 1990 tables for China, Singapore, and Malaysia. The Malaysian transportation sector needs to be improved in energy saving. In Singapore, energy saving is functioning effectively in the transportation sector. China's energy consuming industries are those involving coal, chemistry, steelmaking, ceramics, and earth and quarrying. In Taiwan, improvement needs to be made in the transportation sector. Korea should conserve energy in the transportation sector. In the Philippines, energy needs to be saved in businesses related to water supply, transportation, and fishery.

    Materials related to IEA Greenhouse Gas Rand D Program (IEA/GHG) were analyzed. The Sleipner carbon dioxide underground storage workshop is acting to narrow themes for understanding the technologies, observation methods, and research activities. The IEA/GHG has verified the known facts about ocean storage of carbon dioxide, and discussed the important development targets. Researches were made on improving methane recovery efficiency and the possibility of sealing carbon dioxide by injecting carbon dioxide in order to improve recovery of carbon bed methane. The IEA/GHG has developed a methodology for complete fuel cycles of LNG, and evaluated cost and benefit of reducing greenhouse effect gas emission. A process combining electric power generation, carbon dioxide absorption and hot heat energy utilization can reduce emission of carbon dioxide into atmosphere at relatively low cost and low energy loss. The paper also describes reduction of greenhouse effect gas emitted from cement factories, petroleum refining and petro-chemical industries, and offshore petroleum and gas facilities. It also describes influence of forestry on carbon absorption and timber markets. Case studies have discussed effects of modifying power generation plants. (NEDO)

    Comparative investigation of numerical analysis results of out-of-plane secondary stress caused in a cross beam web around scallop before reinforcement and around cutting portion of vertical stiffeners after reinforcement was carried out. In case of steel truss bridge, there exists difference in axial thrust between outside stringers which continue through a cross beam, and it was revealed that this axial thrust was the main factor which causes partial bending stress in a cross beam web plate. When the lower end of vertical stiffeners is not connected to a cross beam foot flange considering of welding, out-of-plane secondary stress was caused partially in a cross beam web plate around scallop, because of the difficult to transmit adjoining stringers axial thrust difference directly to foot flange. In case of the actual analysis, cross beam web plate around cutting portion of vertical stiffeners causes partial out-of-plane secondary stress in web plate, due to being pressed partially by comparatively high stiffness vertical stiffeners. When repair and reinforcement of steel road truss bridge are carried out, it is necessary to take close attention specially on the structure of the parts in which outside stringers is connected to cross beam. 18 refs., 16 figs.

    This paper summarizes the basic materials related to unified evaluation models for global warming. The unified evaluation is a disciplinary process to combine, interpret and share the information from different scientific disciplinary areas in such a form that the whole cause and effect chain can be evaluated from a macroscopic view. The process has higher utilization value than the evaluation overemphasizing a single academic area, and can provide decision makers with useful information. The process is suitable to model complex interactions and feedback mechanisms in diversified scenes such as climate change. The unified evaluation can identify the policy criteria along with a measure framework having consistency. The evaluation process is repetitive and continuous, wherein a science community can convey comprehensive knowledge and finding to a decision making community. In turn, the decision making side can feed back the experiences and achievements in learning. Execution of the evaluation requires different approaches, such as judgement of specialists including the modeling methods and experience, discovery as a result of applying the policies, and survey methods. The paper also describes the gaming conception, scenario analysis, and unification evaluation methods. (NEDO)

    Effective use of the limited natural resources and preservation of global environments are sought for with the 21st century approaching. In the field of measurement analysis, 21st century type technologies are desired, different from the current ones whose improvement is to be attained through reaching for the limits of sensitivity and resolution. Although the laser device with its performance innovatively advanced has now come to provide light sources for measurement, yet they retain their own flaws of damaging or destroying the object of measurement. Passive measurement techniques need to be developed using natural light or white light as well as laser, which will enable the measurement of the shapes and characteristics of human beings, other animals, and vegetables by use of their radiation, and to determine the kinds and amounts of components of the living environments by use of natural light. Techniques should be developed to measure, in natural light or artificial illumination, shapes and colors, and microscopic substances on solid matters, their temperatures, and reaction processes in factories and laboratories. In this connection, surveys are conducted of technologies for measuring safety, productivity, and environment improving potential. Technologies key to their realization are those involving novel heterodyne interference and light source quality improvement, light amplification, cohering, signal processing, chemistry and mass transfer, establishment of multidimensionality, systematization, etc. (NEDO)

    Morecroft, John

    System dynamics is an approach for thinking about and simulating situations and organisations of all kinds and sizes by visualising how the elements fit together, interact and change over time. This chapter, written by John Morecroft, describes modern system dynamics which retains the fundamentals developed in the 1950s by Jay W. Forrester of the MIT Sloan School of Management. It looks at feedback loops and time delays that affect system behaviour in a non-linear way, and illustrates how dynamic behaviour depends upon feedback loop structures. It also recognises improvements as part of the ongoing process of managing a situation in order to achieve goals. Significantly it recognises the importance of context, and practitioner skills. Feedback systems thinking views problems and solutions as being intertwined. The main concepts and tools: feedback structure and behaviour, causal loop diagrams, dynamics, are practically illustrated in a wide variety of contexts from a hot water shower through to a symphony orchestra and the practical application of the approach is described through several real examples of its use for strategic planning and evaluation.

    The objective of this paper is to demonstrate that a bioenergy system has to be considered as an integrated process in which each stage or step interacts with other steps in the overall process. There are a number of stages in the supply and conversion of woody biomass for energy. Each step in the chain has implications for the next step and for overall system efficiency. The resource can take many forms and will have varying physical and chemical characteristics which will influence the efficiency and cost of conversion. The point in the supply chain at which size and moisture content is reduced and the manner in which it is done is influential in determining feedstock delivered cost and overall system costs. To illustrate the interactions within the overall system, the influence of the nature, size and moisture content of delivered feedstocks on costs of generating electricity via thermal conversion processes is examined using a model developed to investigate the inter-relationships between the stages in the supply chain.

    Mirror neurons are a class of visuomotor neurons, discovered in the monkey premotor cortex and in an anatomically connected area of the inferior parietal lobule, that activate both during action execution and action observation. They constitute a circuit dedicated to match actions made by others with the internal motor representations of the observer. It has been proposed that this matching system enables individuals to understand others' behavior and motor intentions. Here we will describe the main features of mirror neurons in monkeys. Then we will present evidence of the presence of a mirror system in humans and of its involvement in several social-cognitive functions, such as imitation, intention, and emotion understanding. This system may have several implications at a cognitive level and could be linked to specific social deficits in humans such as autism. Recent investigations addressed the issue of the plasticity of the mirror neuron system in both monkeys and humans, suggesting also their possible use in rehabilitation.

    Up to the present the production, transmission and distribution of energy has been considered mostly as a fragmented problem; at best only subsystems have been considered. Today the scale of energy utilization is increasing rapidly, and correspondingly, the reliance of societies on energy. Such strong quantitative increases influence the qualitative nature of energy utilization in most of its aspects. Resources, reserves, reliability and environment are among the key words that may characterize the change in the nature of the energy utilization problem. Energy can no longer be considered an isolated technical and economical problem, rather it is embedded in the ecosphere and the society-technology complex. Restraints and boundary conditions have to be taken into account with the same degree of attention as in traditional technical problems, for example a steam turbine. This results in a strong degree of interweaving. Further, the purpose of providing energy becomes more visible, that is, to make survival possible in a civilized and highly populated world on a finite globe. Because of such interweaving and finiteness it is felt that energy should be considered as a system and therefore the term 'energy systems' is used. The production of energy is only one component of such a system; the handling of energy and the embedding of energy into the global and social complex in terms of ecology, economy, risks and resources are of similar importance. he systems approach to the energy problem needs more explanation. This paper is meant to give an outline of the underlying problems and it is hoped that by so doing the wide range of sometimes confusing voices about energy can be better understood.

    1992-01-01

    The Nuclear Waste Policy Act (NWPA) of 1982 assigned to the Department of Energy (DOE) the responsibility for managing the disposal of spent nuclear fuel and high-level radioactive waste and established the Office of Civilian Radioactive Waste Management (OCRWM) for that purpose. The Secretary of Energy, in his November 1989 report to Congress (DOE/RW-0247), announced three new initiatives for conduct of the Civilian Radioactive Waste Management (CRWM) program. One of these initiatives was to establish improved management structure and procedures. In response, OCRWM performed a management study and the Direct subsequently issued the Management Systems Improvement Strategy (MSIS) on August 10, 1990, calling for a rigorous implementation of systems engineering principles with a special emphasis on functional analysis. This approach establishes a framework for integrating the program management efforts with the technical requirements analysis into a single, unified, and consistent program. The functional analysis approach recognizes that just the facilities and equipment comprising the physical waste management system must perform certain functions, so must certain programmatic and management functions be performed within the program in order to successfully bring the physical system into being

    A moving object such as a container on a conveyor belt is imaged by an optical system onto a charge coupled device array in which the lines of the array are arranged perpendicular to the direction of motion of the object. The speed of movement of the object is sensed to generate electrical signals which are processed to provide shift signals enabling the shifting of data row to row in the array in synchronism with the movement of the container. The electrical charge associated with a given point on the array is transferred from one line to the other until it appears at the last line of the array, from which it is read out in known manner in conjunction with all other electrical charges associated with the row of charge coupled devices in the last line of the array. Due to the integrating effect achieved, the aperture of the imaging system can be much smaller than otherwise would be required, and/or the level of light illumination can be reduced. The imaging system can be applied to X-ray inspection devices, aerial surveillance or scanning of moving documents in copying processes. (author)

    A balanced braking system comprising a plurality of braking assemblies located about a member to be braked. Each of the braking assemblies consists of a spring biased piston of a first material fitted into a body of a different material which has a greater contraction upon cooling than the piston material. The piston is provided with a recessed head portion over which is positioned a diaphragm and forming a space therebetween to which is connected a pressurized fluid supply. The diaphragm is controlled by the fluid in the space to contact or withdraw from the member to be braked. A cooling means causes the body within which the piston is fitted to contract more than the piston, producing a tight shrink fit therebetween. The braking system is particularly applicable for selectively braking an arbor of an electron microscope which immobilizes, for example, a vertically adjustable low temperature specimen holder during observation. The system provides balanced braking forces which can be easily removed and re-established with minimal disturbance to arbor location.

    A system for posting hazardous materials into and out of an enclosure, such as a glovebox, through a port in a wall of the enclosure. The port is normally closed by a door which cooperates with a removable end closure, on a container or the like when the latter is presented to and secured at the port. The container is secured in position at the port by means of a rotatable coupling ring. A single interlock ensures that the door cannot be opened in the absence of a container at the port and also that the container cannot be removed from the port when the door is open. In place of the container, a glove secured to a rigid sleeve may be used to enable the operator to perform a work function within the glovebox. (author)

    Full Text Available In this paper, we revise the classical formulation of the problem depriving it of the concepts that are superfluous from the mathematical point of view. We observe that a number of power stations can be substituted by a single one that behaves equivalently to the entire set. Proceeding in this way, we obtain a variational formulation in its purest sense (without restrictions. This formulation allows us to employ the theory of calculus of variations to the highest degree. We then calculate the equivalent minimizer in the case where the cost functions are second-order polynomials. We prove that the equivalent minimizer is a second-order polynomial with piece-wise constant coefficients. Moreover, it belongs to the class C1. Finally, we present various examples prompted by real systems and perform the proposed algorithms using Mathematica.

    This book presents an overview of the most recent advances in nonlinear science. It provides a unified view of nonlinear properties in many different systems and highlights many  new developments. While volume 1 concentrates on mathematical theory and computational techniques and challenges, which are essential for the study of nonlinear science, this second volume deals with nonlinear excitations in several fields. These excitations can be localized and transport energy and matter in the form of breathers, solitons, kinks or quodons with very different characteristics, which are discussed in the book. They can also transport electric charge, in which case they are known as polarobreathers or solectrons. Nonlinear excitations can influence function and structure in biology, as for example, protein folding. In crystals and other condensed matter, they can modify transport properties, reaction kinetics and interact with defects. There are also engineering applications in electric lattices, Josephson junction a...

    1998-01-01

    The NJOY Nuclear Data Processing System is used to convert evaluated nuclear data in ENDF format into forms useful for applications. The NJOY code is a modular computer code designed to read evaluated data in ENDF format, transform the data in various ways, and output the results as libraries designed to be used in various applications. The modules are essentially independent programs, and they communicate with each other using input and output files, plus a very few common variables. The NJOY code can work with neutrons, photons, and charged particles. The evaluated nuclear data are reconstructed to pointwise cross sections from ENDF resonance parameters and interpolation schemes. The pointwise data can be Doppler broadened to the temperatures requested by users. The data in unresolved energy range can be computed to effective self-shielded pointwise cross sections. The cross sections and scattering matrices for free or bound scatterers in the thermal energy range are able to be produced. The self-shielded multigroup cross sections, group-to-group scattering matrices, photon-production matrices, and charged-particle cross sections from pointwise data can be generated for various application codes

    This paper reports that world styrene demand, paced by a near doubling of combined requirements in East Asia and Oceania, could reach 19.3 million metric tons by 2000, an average growth rate of 3.7%/year. So concludes Chem Systems Inc., Tarrytown, N.Y., in a study of world styrene markets through the end of the century. Pacific Rim styrene production and consumption throughout the 1990s are predicted to make up increasingly larger shares of world markets, while demand and production lag in the U.S. and western Europe. Demand and capacity in other parts of the world will grow in real terms, increasing combined market shares only slightly. Most of the increase will be driven by demand in East Asia and Oceania, where consumption by century's end is expected to increase 4.48 million metric tons from 2.25 million tons in 1991. Meantime, Japan's styrene demand in 2000 is projected at 2.64 million tons, a 500,000 ton increase from 1991 demand but a net market loss of 1.9%

    The DO cryogenic system is controlled by a TI565-PLC based control system. This allows the system to be unmanned when in steady state operation. System experts will need to be contacted when system parameters exceed normal operating points and reach alarm setpoints. The labwide FIRUS system provides one alarm monitor and communication link. An autodialer provides a second and more flexible alarm monitor and communication link. The autodialer monitors contact points in the control system and after receiving indication of an alarm accesses a list of experts which it calls until it receives an acknowledgement. There are several manufacturers and distributors of autodialer systems. This EN explains the search process the DO cryo group used to fmd an autodialer system that fit the cryo system's needs and includes information and specs for the unit we chose.

    Decisive parts of the Western political system have demonstrated a seemingly surprising misinterpretation of military might. As Madelaine Albright has suggested, the mighty perceived themselves as "almighty". Political power seems to have invested in instrumental coercive power relations and found...... military coercion to be the appropriate mean. Using the system theory and the theory of systemic risks displayed by the German sociologist Niklas Luhmann the article demonstrates how military systems due to their own autonomy and autopoiesis do not fit into the idea of political government....... The Clausewitzian ideal of a political system that could continue its power games by means of war was moderated by Clausewitz' own analysis of "friction". How can a political system be so blind towards the possibilities of another system? What are the risks of systemic blind spots? The argument of the paper...

    2012-08-01

    Systems Biology is about combining theory, technology, and targeted experiments in a way that drives not only data accumulation but knowledge as well. The challenge in Systems Biomedicine is to furthermore translate mechanistic insights in biological systems to clinical application, with the central aim of improving patients' quality of life. The challenge is to find theoretically well-chosen models for the contextually correct and intelligible representation of multi-scale biological systems. In this review, we discuss the current state of Systems Biology, highlight the emergence of Systems Biomedicine, and highlight some of the topics and views that we think are important for the efficient application of Systems Theory in Biomedicine.

    2011-01-01

    The implementation of an integrated system health management (ISHM) capability is fundamentally linked to the management of data, information, and knowledge (DIaK) with the purposeful objective of determining the health of a system. It is akin to having a team of experts who are all individually and collectively observing and analyzing a complex system, and communicating effectively with each other in order to arrive at an accurate and reliable assessment of its health. In this paper, concepts, procedures, and approaches are presented as a foundation for implementing an intelligent systems ]relevant ISHM capability. The capability stresses integration of DIaK from all elements of a system. Both ground-based (remote) and on-board ISHM capabilities are compared and contrasted. The information presented is the result of many years of research, development, and maturation of technologies, and of prototype implementations in operational systems.

    1986-01-01

    Utilization of Probabilistic Risk Assessment (PRA) related information in the day-to-day operation of plant systems has, in the past, been impracticable due to the size of the computers needed to run PRA codes. This paper discusses a microcomputer-based database system which can greatly enhance the capability of operators or regulators to incorporate PRA methodologies into their routine decision making. This system is called the System Analysis and Risk Assessment (SARA) system. SARA was developed by EG and G Idaho, Inc. at the Idaho National Engineering Laboratory to facilitate the study of frequency and consequence analyses of accident sequences from a large number of light water reactors (LWRs) in this country. This information is being amassed by several studies sponsored by the United States Nuclear Regulatory Commission (USNRC). To meet the need of portability and accessibility, and to perform the variety of calculations necessary, it was felt that a microcomputer-based system would be most suitable

  8. Systems engineering for very large systems

    Science.gov (United States)

    Lewkowicz, Paul E.

    Very large integrated systems have always posed special problems for engineers. Whether they are power generation systems, computer networks or space vehicles, whenever there are multiple interfaces, complex technologies or just demanding customers, the challenges are unique. 'Systems engineering' has evolved as a discipline in order to meet these challenges by providing a structured, top-down design and development methodology for the engineer. This paper attempts to define the general class of problems requiring the complete systems engineering treatment and to show how systems engineering can be utilized to improve customer satisfaction and profit ability. Specifically, this work will focus on a design methodology for the largest of systems, not necessarily in terms of physical size, but in terms of complexity and interconnectivity.

  9. Epilogue: Systems Approaches and Systems Practice

    Science.gov (United States)

    Reynolds, Martin; Holwell, Sue

    Each of the five systems approaches discussed in this volume: system dynamics (SD), the viable systems model (VSM), strategic options development and analysis (SODA), soft systems methodology (SSM) and critical systems heuristics (CSH) has a pedigree. Not in the sense of the sometimes absurd spectacle of animals paraded at dog shows. Rather, their pedigree derives from their systems foundations, their capacity to evolve and their flexibility in use. None of the five approaches has developed out of use in restricted and controlled contexts of either low or high levels of complicatedness. Neither has any one of them evolved as a consequence of being applied only to situations with either presumed stakeholder agreement on purpose, or courteous disagreement amongst stakeholders, or stakeholder coercion. The compilation is not a celebration of abstract ‘methodologies', but of theoretically robust approaches that have a genuine pedigree in practice.

    We construct a large family of evidently integrable Hamiltonian systems which are generalizations of the KM system. The algorithm uses the root system of a complex simple Lie algebra. The Hamiltonian vector field is homogeneous cubic but in a number of cases a simple change of variables transforms such a system to a quadratic Lotka-Volterra system. We present in detail all such systems in the cases of A3, A4 and we also give some examples from higher dimensions. We classify all possible Lotka-Volterra systems that arise via this algorithm in the An case.

    Full Text Available The main message of this paper is that systemism is best suited for transdisciplinary studies. A description of disciplinary sciences, transdisciplinary sciences and systems sciences is given, along with their different definitions of aims, scope and tools. The rationale for transdisciplinarity is global challenges, which are complex. The rationale for systemism is the concretization of understanding complexity. Drawing upon Ludwig von Bertalanffy’s intention of a General System Theory, three items deserve attention—the world-view of a synergistic systems technology, the world picture of an emergentist systems theory, and the way of thinking of an integrationist systems method.

    Under a variety of rubrics (e.g., complexity, self-constructing systems, dissipative structures), interest has recently burgeoned in applying principles of complex systems to a wide variety of scientific issues. A major concern is with emergent properties of systems not derivable from the properties of components of the systems. In this paper, some elementary aspects of "systems" considerations are applied to phenomena of alcohol pharmacogenetics. It is likely that whole new families of informative phenotypes can be generated by this approach.

  11. Systems Theory and Systems Approach to Leadership

    Directory of Open Access Journals (Sweden)

    Dr.Sc. Berim Ramosaj

    2014-06-01

    Full Text Available Systems theory is product of the efforts of many researchers to create an intermediate field of coexistence of all sciences. If not for anything else, because of the magnitude that the use of systemic thinking and systemic approach has taken, it has become undisputed among the theories. Systems theory not only provides a glossary of terms with which researchers from different fields can be understood, but provides a framework for the presentation and interpretation of phenomena and realities. This paper addresses a systematic approach to leadership, as an attempt to dredge leadership and systems theory literature to find the meeting point. Systems approach is not an approach to leadership in terms of a manner of leader’s work, but it’s the leader's determination to factorize in his leadership the external environment and relationships with and among elements. Leader without followers is unable to exercise his leadership and to ensure their conviction he should provide a system, a structure, a purpose, despite the alternative chaos. Systems approach clarifies the thought on the complexity and dynamism of the environment and provides a framework for building ideas. If the general system theory is the skeleton of science (Boulding: 1956, this article aims to replenish it with leadership muscles by prominent authors who have written on systems theory and leadership, as well as through original ideas. In this work analytical methods were used (by analyzing approaches individually as well as synthetic methods (by assaying individual approaches in context of entirety. The work is a critical review of literature as well as a deductive analysis mingled with models proposed by authors through inductive analysis. Meta-analysis has been used to dissect the interaction and interdependence between leadership approaches.

    The development of new distribution automation applications is considerably wide nowadays. One of the most interesting areas is the development of a distribution management system (DMS) as an expansion of the traditional SCADA system. At the power transmission level such a system is called an energy management system (EMS). The idea of these expansions is to provide supporting tools for control center operators in system analysis and operation planning. The needed data for new applications is mainly available in some existing systems. Thus the computer systems of utilities must be integrated. The main data source for the new applications in the control center are the AM/FM/GIS (i.e. the network database system), the SCADA, and the customer information system (CIS). The new functions can be embedded in some existing computer system. This means a strong dependency on the vendor of the existing system. An alternative strategy is to develop an independent system which is integrated with other computer systems using well-defined interfaces. The latter approach makes it possible to use the new applications in various computer environments, having only a weak dependency on the vendors of the other systems. In the research project this alternative is preferred and used in developing an independent distribution management system

    2004-12-30

    Physical analogs have shown considerable promise for understanding the behavior of complex adaptive systems, including macroeconomics, biological systems, social networks, and electric power markets. Many of today's most challenging technical and policy questions can be reduced to a distributed economic control problem. Indeed, economically based control of large-scale systems is founded on the conjecture that the price-based regulation (e.g., auctions, markets) results in an optimal allocation of resources and emergent optimal system control. This report explores the state-of-the-art physical analogs for understanding the behavior of some econophysical systems and deriving stable and robust control strategies for using them. We review and discuss applications of some analytic methods based on a thermodynamic metaphor, according to which the interplay between system entropy and conservation laws gives rise to intuitive and governing global properties of complex systems that cannot be otherwise understood. We apply these methods to the question of how power markets can be expected to behave under a variety of conditions.

    1992-06-01

    The ITER reference system uses low-temperature water for heat removal and high-temperature helium for bake-out. As these systems share common equipment, bake-out cannot be performed until the cooling system is drained and dried, and the reactor cannot be started until the helium has been purged from the cooling system. This study examines the feasibility of using a single high-temperature fluid to perform both heat removal and bake-out. The high temperature required for bake-out would also be in the range for power production. The study examines cost, operational benefits, and impact on reactor safety of two options: a high-pressure water system, and a low-pressure organic system. It was concluded that the cost savings and operational benefits are significant; there are no significant adverse safety impacts from operating either the water system or the organic system; and the capital costs of both systems are comparable

    The System Performance Optimization has become an important and difficult field for large scientific computer centres. Important because the centres must satisfy increasing user demands at the lowest possible cost. Difficult because the System Performance Optimization requires a deep understanding of hardware, software and workload. The optimization is a dynamic process depending on the changes in hardware configuration, current level of the operating system and user generated workload. With the increasing complication of the computer system and software, the field for the optimization manoeuvres broadens. The hardware of two manufacturers IBM and CDC is discussed. Four IBM and two CDC operating systems are described. The description concentrates on the organization of the operating systems, the job scheduling and I/O handling. The performance definitions, workload specification and tools for the system stimulation are given. The measurement tools for the System Performance Optimization are described. The results of the measurement and various methods used for the operating system tuning are discussed. (Auth.)

    The Upgraded RECOVER (Remote Continual Verification) system is a communication system for remote continual verification of security and safeguards status of nuclear material in principal nuclear facilities. The system is composed of a command center and facility sub-systems. A command center is a mini-computer system to process C/S (Containment and Surveillance) status data. Facility sub-systems consists of OSM (On-site Multiplexer), MU (Monitoring Unit) and C/S sensor. The system uses public telephone network for communication between a command center and facility sub-systems, and it encrypts communication data to prevent falsification and wiretapping by unauthorized persons. This system inherits the design principle of RECOVER system that was tested by IAEA before. We upgraded and expanded its capabilities more than those of RECOVER. The development of this system began in 1983, and it finished in 1987. Performance tests of the system were carried out since 1987. It showed a farely good result with some indications which should need further improvements. The Upgraded RECOVER system provides timely information about the status of C/S systems, which could contribute to the reduction of inspection effort and the improvement of cost performance.

    Distributed intelligent systems can be distinguished by the models that they use. The model developed focuses on layered multiagent system conceived of as a bureaucracy in which a distributed data base serves as a central means of communication. The various generic bureaus of such a system is described and a basic vocabulary for such systems is presented. In presenting the bureaus and vocabularies, special attention is given to the sorts of reasonings that are appropriate. A bureaucratic model has a hierarchy of master system and work group that organizes E agents and B agents. The master system provides the administrative services and support facilities for the work groups.

    1993-11-01

    In this article, we looked at some decisions that apply to the design of reliable computer systems. We began with a discussion of several terms such as testability, then described some systems that call for highly reliable hardware and software. The article concluded with a discussion of methods that can be used to achieve higher reliability in computer systems. Reliability and fault tolerance in computers probably will continue to grow in importance. As more and more systems are computerized, people will want assurances about the reliability of these systems, and their ability to work properly even when sub-systems fail.

    It is generally very difficult to solve nonlinear systems, and such systems often possess chaotic solutions. In the rare event that a system is completely solvable, it is said to integrable. Such systems never have chaotic solutions. Using the Inverse Scattering Transform Method (ISTM) two...... particular configurations of the Discrete Self-Trapping (DST) system are shown to be completely solvable. One of these systems includes the Toda lattice in a certain limit. An explicit integration is carried through for this Near-Toda lattice. The Near-Toda lattice is then generalized to include singular...

    The objective of this analysis is to identify issues and criteria that apply to the design of the Subsurface Emplacement Transportation System (SET). The SET consists of the track used by the waste package handling equipment, the conductors and related equipment used to supply electrical power to that equipment, and the instrumentation and controls used to monitor and operate those track and power supply systems. Major considerations of this analysis include: (1) Operational life of the SET; (2) Geometric constraints on the track layout; (3) Operating loads on the track; (4) Environmentally induced loads on the track; (5) Power supply (electrification) requirements; and (6) Instrumentation and control requirements. This analysis will provide the basis for development of the system description document (SDD) for the SET. This analysis also defines the interfaces that need to be considered in the design of the SET. These interfaces include, but are not limited to, the following: (1) Waste handling building; (2) Monitored Geologic Repository (MGR) surface site layout; (3) Waste Emplacement System (WES); (4) Waste Retrieval System (WRS); (5) Ground Control System (GCS); (6) Ex-Container System (XCS); (7) Subsurface Electrical Distribution System (SED); (8) MGR Operations Monitoring and Control System (OMC); (9) Subsurface Facility System (SFS); (10) Subsurface Fire Protection System (SFR); (11) Performance Confirmation Emplacement Drift Monitoring System (PCM); and (12) Backfill Emplacement System (BES)

    The solar power satellite system is a system that converts solar energy into electric energy in the space, transmits power to earth through wireless resort such as microwave and supplies energy of new concept. In order to realize this system it is necessary to have new technologies such as space power transmission at low cost, construction of large space buildings and wireless high power transmission. In this paper, the principles, characteristics and the necessary technology of this system were explained. Besides Japan`s SPS2000 Plan (cooperative research by universities, government agencies and private corporations on the model of solar power satellite) the group of Europe, Russia and the United States has also proposed some ideas concerning the solar power satellite system. As far as the microwave power transmission, which is the key technology for solar power satellite system, is concerned, ground demonstration tests at the level of several tens of kW are discussed in Canada and France. 3 refs., 3 figs.

    Hughes, Peter M. (Inventor); Luczak, Edward C. (Inventor)

    1998-01-01

    A system and method provides for the creation of a highly graphical expert system without the need for programming in code. An expert system is created by initially building a data interface, defining appropriate Mission, User-Defined, Inferred, and externally-generated GenSAA (EGG) data variables whose data values will be updated and input into the expert system. Next, rules of the expert system are created by building appropriate conditions of the rules which must be satisfied and then by building appropriate actions of rules which are to be executed upon corresponding conditions being satisfied. Finally, an appropriate user interface is built which can be highly graphical in nature and which can include appropriate message display and/or modification of display characteristics of a graphical display object, to visually alert a user of the expert system of varying data values, upon conditions of a created rule being satisfied. The data interface building, rule building, and user interface building are done in an efficient manner and can be created without the need for programming in code.

  12. Business system: Sustainable development and anticipatory system

    Directory of Open Access Journals (Sweden)

    Vojko Potočan

    2002-01-01

    Full Text Available The existence and development of humankind depends mainly upon the co-ordinated operation of all areas and levels of human activity. However, in theory and in practice there is no model of operation, which would provide a harmonized and target oriented development. A partial solution is offered by sustainable development, which tries to define and carry out common goals of mankind with a harmonized implementation of human activities at all levels of its living and behaviour. Companies belong to central institutions of modern society which essentially co–create the sustainability of society. The company’s endeavour by simulation to prepare models of their goals concerning their internal and external environment. On the base of systemic treatment, we can define companies as business system, which can survive in a log-run only on the basis of sustainable development. The business system can also be supported by the application of the anticipatory systems. The anticipatory systems can be, in this sense, understood as an entity of the methodological approach, techniques and modes of work. Their characteristics have, a direct impact on the determination of goals, on the orientation of operation, and hence on the achievement of the business system results.

  13. Operating System for Runtime Reconfigurable Multiprocessor Systems

    Directory of Open Access Journals (Sweden)

    Diana Göhringer

    2011-01-01

    Full Text Available Operating systems traditionally handle the task scheduling of one or more application instances on processor-like hardware architectures. RAMPSoC, a novel runtime adaptive multiprocessor System-on-Chip, exploits the dynamic reconfiguration on FPGAs to generate, start and terminate hardware and software tasks. The hardware tasks have to be transferred to the reconfigurable hardware via a configuration access port. The software tasks can be loaded into the local memory of the respective IP core either via the configuration access port or via the on-chip communication infrastructure (e.g. a Network-on-Chip. Recent-series of Xilinx FPGAs, such as Virtex-5, provide two Internal Configuration Access Ports, which cannot be accessed simultaneously. To prevent conflicts, the access to these ports as well as the hardware resource management needs to be controlled, e.g. by a special-purpose operating system running on an embedded processor. For that purpose and to handle the relations between temporally and spatially scheduled operations, the novel approach of an operating system is of high importance. This special purpose operating system, called CAP-OS (Configuration Access Port-Operating System, which will be presented in this paper, supports the clients using the configuration port with the services of priority-based access scheduling, hardware task mapping and resource management.

    The objectives of an integrated security system are to detect intruders and unauthorized activities with a high degree of reliability and the to deter and delay them until effective response/engagement can be accomplished. Definition of an effective integrated security system requires proper application of a system engineering methodology. This paper summarizes a methodology and describes its application to the problem of integrated security system definition. This process includes requirements identification and analysis, allocation of identified system requirements to the subsystem level and provides a basis for identification of synergistic subsystem elements and for synthesis into an integrated system. The paper discusses how this is accomplished, emphasizing at each step how system integration and subsystem synergism is considered. The paper concludes with the product of the process: implementation of an integrated security system

    A pulse height analyzer terminal system PHATS has been developed for online data processing via JAERI-TOKAI computer network. The system is controled by using a micro-computer MICRO-8 which was developed for the JAERI-TOKAI network. The system program consists of two subprograms, online control system ONLCS and pulse height analyzer control system PHACS. ONLCS links the terminal with the conversational programming system of FACOM 230/75 through the JAERI-TOKAI network and controls data processing in TSS and remote batch modes. PHACS is used to control INPUT/OUTPUT of data between pulse height analyzer and cassette-MT or typewriter. This report describes the hardware configuration and the system program in detail. In the appendix, explained are real time monitor, type of message, PEX to PEX protocol and Host to Host protocol, required for the system programming. (author)

  9. Saturated Switching Systems

    CERN Document Server

    Benzaouia, Abdellah

    2012-01-01

    Saturated Switching Systems treats the problem of actuator saturation, inherent in all dynamical systems by using two approaches: positive invariance in which the controller is designed to work within a region of non-saturating linear behaviour; and saturation technique which allows saturation but guarantees asymptotic stability. The results obtained are extended from the linear systems in which they were first developed to switching systems with uncertainties, 2D switching systems, switching systems with Markovian jumping and switching systems of the Takagi-Sugeno type. The text represents a thoroughly referenced distillation of results obtained in this field during the last decade. The selected tool for analysis and design of stabilizing controllers is based on multiple Lyapunov functions and linear matrix inequalities. All the results are illustrated with numerical examples and figures many of them being modelled using MATLAB®. Saturated Switching Systems will be of interest to academic researchers in con...

    Cross disciplinary biometric systems help boost the performance of the conventional systems. Not only is the recognition accuracy significantly improved, but also the robustness of the systems is greatly enhanced in the challenging environments, such as varying illumination conditions. By leveraging the cross disciplinary technologies, face recognition systems, fingerprint recognition systems, iris recognition systems, as well as image search systems all benefit in terms of recognition performance.  Take face recognition for an example, which is not only the most natural way human beings recognize the identity of each other, but also the least privacy-intrusive means because people show their face publicly every day. Face recognition systems display superb performance when they capitalize on the innovative ideas across color science, mathematics, and computer science (e.g., pattern recognition, machine learning, and image processing). The novel ideas lead to the development of new color models and effective ...

    Traditionally safety systems intended for protecting personnel from electrical and radiation hazards at particle accelerator laboratories have made extensive use of electromechanical relays. These systems have the advantage of high reliability and allow the designer to easily implement fail-safe circuits. Relay based systems are also typically simple to design, implement, and test. As systems, such as those presently under development at the Superconducting Super Collider Laboratory (SSCL), increase in size, and the number of monitored points escalates, relay based systems become cumbersome and inadequate. The move toward Programmable Electronic Safety Systems is becoming more widespread and accepted. In developing these systems there are numerous precautions the designer must be concerned with. Designing fail-safe electronic systems with predictable failure states is difficult at best. Redundancy and self-testing are prime examples of features that should be implemented to circumvent and/or detect failures. Programmable systems also require software which is yet another point of failure and a matter of great concern. Therefore the designer must be concerned with both hardware and software failures and build in the means to assure safe operation or shutdown during failures. This paper describes features that should be considered in developing safety systems and describes a system recently installed at the Accelerator Systems String Test (ASST) facility of the SSCL

    The MSRC Spill Operation System (SOS) is a tool for the support of decision-making at the time of a catastrophic oil spill. SOS provides MSRC decision-makers with access to information about the source of the spill, the spill environment, and the availability of spill response resources. This system is designed to meet the information needs of a Response Supervisor, an Environmental Advisor, Logistics/Maintenance Supervisor, Operations Supervisor, and the MSRC Regional General Manager. The SOS project Objectives are: (1) integrate currently available data, systems, and technologies; (2) develop an application that effectively supports mobilized operations and can be adapted to support normal operations; (3) ensure that the development of computer applications is driven by user needs and not by technology; and (4) coordinate with government and other industry organizations to avoid duplication of effort. Design Objectives for SOS are: (1) centralize management information storage while decentralizing decision making capabilities; (2) boost User confidence by providing a system that is easy to learn, easy to use, and is open-quotes Sailor Proofclose quotes; and (3) use visualization technology in providing spill related information. This approach includes the use of Geographic Information System (GIS) technology for maps and geographically associated resource; and support MSRC's concept of operation which includes - a swift notification of response personnel; fast mobilization of response resources; and accurate tracking of resources during a spill. MSRC is organized into five responsibility regions

    This report summarizes runtime system challenges for exascale computing, that follow from the fundamental challenges for exascale systems that have been well studied in past reports, e.g., [6, 33, 34, 32, 24]. Some of the key exascale challenges that pertain to runtime systems include parallelism, energy efficiency, memory hierarchies, data movement, heterogeneous processors and memories, resilience, performance variability, dynamic resource allocation, performance portability, and interoperability with legacy code. In addition to summarizing these challenges, the report also outlines different approaches to addressing these significant challenges that have been pursued by research projects in the DOE-sponsored X-Stack and OS/R programs. Since there is often confusion as to what exactly the term “runtime system” refers to in the software stack, we include a section on taxonomy to clarify the terminology used by participants in these research projects. In addition, we include a section on deployment opportunities for vendors and government labs to build on the research results from these projects. Finally, this report is also intended to provide a framework for discussing future research and development investments for exascale runtime systems, and for clarifying the role of runtime systems in exascale software.

    We present recent work on building and scaling trustworthy systems with formal, machine-checkable proof from the ground up, including the operating system kernel, at the level of binary machine code. We first give a brief overview of the seL4 microkernel verification and how it can be used to build verified systems. We then show two complementary techniques for scaling these methods to larger systems: proof engineering, to estimate verification effort; and code/proof co-generation, for scalable development of provably trustworthy applications.This article is part of the themed issue 'Verified trustworthy software systems'. © 2017 The Author(s).

    The development of new distribution automation applications is considerably wide nowadays. One of the most interesting areas is the development of a distribution management system (DMS) as an expansion to the traditional SCADA system. At the power transmission level such a system is called an energy management system (EMS). The idea of these expansions is to provide supporting tools for control center operators in system analysis and operation planning. Nowadays the SCADA is the main computer system (and often the only) in the control center. However, the information displayed by the SCADA is often inadequate, and several tasks cannot be solved by a conventional SCADA system. A need for new computer applications in control center arises from the insufficiency of the SCADA and some other trends. The latter means that the overall importance of the distribution networks is increasing. The slowing down of load-growth has often made network reinforcements unprofitable. Thus the existing network must be operated more efficiently. At the same time larger distribution areas are for economical reasons being monitored at one control center and the size of the operation staff is decreasing. The quality of supply requirements are also becoming stricter. The needed data for new applications is mainly available in some existing systems. Thus the computer systems of utilities must be integrated. The main data source for the new applications in the control center are the AM/FM/GIS (i.e. the network database system), the SCADA, and the customer information system (CIS). The new functions can be embedded in some existing computer system. This means a strong dependency on the vendor of the existing system. An alternative strategy is to develop an independent system which is integrated with other computer systems using well-defined interfaces. The latter approach makes it possible to use the new applications in various computer environments, having only a weak dependency on the

    The Nuclear Energy for Rocket Vehicle Application (NERVA) program of the 1960's and early 1970's was dramatically successful, with no major failures during the entire testing program. This success was due in large part to the successful development of a systems engineering process. Systems engineering, properly implemented, involves all aspects of the system design and operation, and leads to optimization of theentire system: cost, schedule, performance, safety, reliability, function, requirements, etc. The process must be incorporated from the very first and continued to project completion. This paper will discuss major aspects of the NERVA systems engineering effort, and consider the implications for current nuclear propulsion efforts

    At present, 23 units of PWR type reactors have been operated in Japan since the start of Mihama Unit 1 operation in 1970 and various improvements have been made to upgrade operability of power stations as well as reliability and safety of power plants. As the share of nuclear power increases, further improvements of operating performance such as load following capability will be requested for power stations with more reliable and safer operation. This article outlined the reactor control system of PWR type reactors and described the control performance of power plants realized with those systems. The PWR control system is characterized that the turbine power is automatic or manually controlled with request of the electric power system and then the nuclear power is followingly controlled with the change of core reactivity. The system mainly consists of reactor automatic control system (control rod control system), pressurizer pressure control system, pressurizer water level control system, steam generator water level control system and turbine bypass control system.

    1988-01-01

    Purpose: To previously set a nuclear reactor toward safety side by the reactor scram if an emergency core cooling system is failed to operate. Constitution If abnormality occurs in an emergency core cooling system or an aqueous boric acid injection system, a reactor protection system is operated and, if the reactor protection system shows an abnormal state, a control rod withdrawal inhibition system is operated as a fundamental way. For instance, when the driving power source voltage for the emergency core cooling system is detected and, if it is lower than a predetermined value, the reactor protection system is operated. Alternatively, if the voltage goes lower than the predetermined value, the control rod withdrawal is inhibited. In addition, stopping for the feedwater system is inhibited. Further, integrity of the driving means for the emergency core cooling system is positively checked and the protection function is operated depending on the result of check. Since the nuclear reactor can be set toward the safety side even if the voltage for the driving power source of the aqueous boric acid injection system is lower than a predetermined value, the reactor safety can further be improved.

    Full Text Available Recently there have been many important and valuable developments in the communication industry. The huge increase in the sound, data and visual communications has caused a parallel increase in the demand for systems with wider capacity, higher speed and higher quality. Communication systems that use light to transfer data are immensely increased. There have recently many systems in which glass or plastic fiber cables were developed for light wave to be transmitted from a source to a target place. Fiber optic systems, are nowadays widely used in energy transmission control systems, medicine, industry and lighting. The basics of the system is, movement of light from one point to another point in fiber cable with reflections. Fiber optic lighting systems are quite secure than other lighting systems and have flexibility for realizing many different designs. This situation makes fiber optics an alternative for other lighting systems. Fiber optic lighting systems usage is increasing day-by-day in our life.

    The advent of the World Wide Web (Web) and the ability to easily put data repositories on-line has resulted in a proliferation of digital libraries. The heterogeneity of the underlying systems, the autonomy of the individual sites, and distributed nature of the technology has made both interoperability across the sites and the search for resources within a site major research topics. This article will describe a system that addresses both issues using standard Web protocols and meta-data labels to implement an inventory of on-line resources across a group of sites. The success of this system is strongly dependent on the existence of and adherence to a standards architecture that guides the management of meta-data within participating sites.

    2005-01-01

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

    1991-01-01

    Terrorism and other aspects of world political instability have created a high demand for temporary physical protection systems within the nuclear materials management community. They can be used when vehicles carrying important assets are away from their permanent fixed site location, around areas where experiments are being temporarily conducted, around construction areas and one portions of a fixed site physical security system which is temporarily inoperable. Physical security systems can be grouped into four categories: tactical, portable, semi-permanent, and fixed. The resources and experience gained at Sandia National Laboratories in over forty years of developing and implementing security systems for protecting nuclear weapons and fixed nuclear facilities is now being applied to temporary physical security systems. This paper emphasizes temporary physical security systems and their component parts that are presently available and identify additional system-subsystem objectives, requirements, and concepts

    The purpose of the meeting was to discuss and develop cost-estimating methods for heavy-ion fusion accelerator systems. The group did not consider that its purpose was to make technical judgments on proposed systems, but to develop methods for making reasonable cost estimates of these systems. Such estimates will, it is hoped, provide material for systems studies, will help in guiding research and development efforts by identifying high-leverage subsystems (areas that account for a significant part of total system cost and that might be reduced in cost by further technical development) and to begin to provide data to aid in an eventual decision on the optimum type of accelerator for heavy-ion fusion. The systems considered as examples are: (1) injection system; (2) Wideroe linac; (3) Alvarez linac; (4) induction linac; (5) superconducting accumulator ring; (6) synchrotron; (7) final rf bunching; and (8) final beam transport to target

    Since the last ICALEPCS, a small multi-region team has developed a reference design model for a control system for the International Linear Collider as part of the ILC Global Design Effort. The scale and performance parameters of the ILC accelerator require new thinking in regards to control system design. Technical challenges include the large number of accelerator systems to be controlled, the large scale of the accelerator facility, the high degree of automation needed during accelerator operations, and control system equipment requiring 'Five Nines' availability. The R and D path for high availability touches the control system hardware, software, and overall architecture, and extends beyond traditional interfaces into the technical systems. Software considerations for HA include fault detection through exhaustive out-of-band monitoring and automatic state migration to redundant systems, while the telecom industry's emerging ATCA standard - conceived, specified, and designed for High Availability - is being evaluated for suitability for ILC front-end electronics.

    2010-01-01

    For senior-level undergraduate and first and second year graduate systems engineering and related courses. A total life-cycle approach to systems and their analysis. This practical introduction to systems engineering and analysis provides the concepts, methodologies, models, and tools needed to understand and implement a total life-cycle approach to systems and their analysis. The authors focus first on the process of bringing systems into being--beginning with the identification of a need and extending that need through requirements determination, functional analysis and allocation, design synthesis, evaluation, and validation, operation and support, phase-out, and disposal. Next, the authors discuss the improvement of systems currently in being, showing that by employing the iterative process of analysis, evaluation, feedback, and modification, most systems in existence can be improved in their affordability, effectiveness, and stakeholder satisfaction.

    Well designed large systems include many instrument taking data. These data are used in a variety of ways. They are used to control the system and its components, to monitor system and component health, and often for historical or financial purposes. This paper discusses a new method of using data from low level instrumentation to monitor system and component health. The method uses the covariance of instrument outputs to calculate a measure of system change. The method involves no complicated modeling since it is not a parameter estimation algorithm. The method is iterative and can be implemented on a computer in real time. Examples are presented for a metal lathe and a high efficiency particulate air (HEPA) filter. It is shown that the proposed method is quite sensitive to system changes such as wear out and failure. The method is useful for low level system diagnostics and fault detection

    Smith, D.J.

    1991-01-01

    This paper reports that instrument manufacturers must develop standard network interfaces to pull together interrelated systems such as automatic start-up, optimization programs, and online diagnostic systems. In the past individual control system manufacturers have developed their own data highways with proprietary hardware and software designs. In the future, electric utilities will require that future systems, irrespective of manufacturer, should be able to communicate with each other. Until now the manufactures of control systems have not agreed on the standard high-speed data highway system. Currently, the Electric Power Research Institute (EPRI), in conjunction with several electric utilities and equipment manufactures, is working on developing a standard protocol for communicating between various manufacturers' control systems. According to N. Michael of Sargent and Lundy, future control room designs will require that more of the control and display functions be accessible from the control room through CRTs. There will be less emphasis on traditional hard-wired control panels

    Hydropneumatic suspensions systems combine the excellent properties of gas springs with the favourable damping properties of hydraulic fluids. The advantages of these systems are particularly appropriate for automotive applications, such as passenger cars, trucks and agricultural equipment. In this book, Dr. Bauer provides an extensive overview of hydropneumatic suspension systems. Starting with a comparison of different types of suspension systems, the author subsequently describes the theoretical background associated with spring and damping characteristics of hydropneumatic systems and furthermore explains the design of the most important system components. Additionally he gives an overview of level control systems and various special functions. Finally the technology is illustrated by design examples and the outlook for future hydropneumatic suspensions is discussed. (orig.)

    A true Geographic Information System (GIS) is a computer mapping system with spatial analysis ability and cartographic accuracy that will offer many different projections. GIS has evolved to become an everyday tool for a wide range of users including oil companies, worldwide. Other systems are designed to allow oil and gas companies to keep their upstream data in the same format. Among these are the Public Petroleum Data Model developed by Gulf Canada, Digitech and Applied Terravision Systems of Calgary, the system developed and marketed by the Petrotechnical Open Software Corporation in the United States, and the Mercury projects by IBM. These have been developed in an effort to define an industry standard. The advantages and disadvantages of open and closed systems were discussed. Factors to consider when choosing a GIS system such as overall performance, area of use and query complexity, were reviewed. 3 figs

    Ubiquitous annotation systems allow users to annotate physical places, objects, and persons with digital information. Especially in the field of location based information systems much work has been done to implement adaptive and context-aware systems, but few efforts have focused on the general...... requirements for linking information to objects in both physical and digital space. This paper surveys annotation techniques from open hypermedia systems, Web based annotation systems, and mobile and augmented reality systems to illustrate different approaches to four central challenges ubiquitous annotation...... systems have to deal with: anchoring, structuring, presentation, and authoring. Through a number of examples each challenge is discussed and HyCon, a context-aware hypermedia framework developed at the University of Aarhus, Denmark, is used to illustrate an integrated approach to ubiquitous annotations...

  5. Synchronization of chaotic systems

    Pecora, Louis M.; Carroll, Thomas L.

    2015-01-01

    We review some of the history and early work in the area of synchronization in chaotic systems. We start with our own discovery of the phenomenon, but go on to establish the historical timeline of this topic back to the earliest known paper. The topic of synchronization of chaotic systems has always been intriguing, since chaotic systems are known to resist synchronization because of their positive Lyapunov exponents. The convergence of the two systems to identical trajectories is a surprise. We show how people originally thought about this process and how the concept of synchronization changed over the years to a more geometric view using synchronization manifolds. We also show that building synchronizing systems leads naturally to engineering more complex systems whose constituents are chaotic, but which can be tuned to output various chaotic signals. We finally end up at a topic that is still in very active exploration today and that is synchronization of dynamical systems in networks of oscillators

  9. Intelligent systems engineering methodology

    1990-01-01

    An added challenge for the designers of large scale systems such as Space Station Freedom is the appropriate incorporation of intelligent system technology (artificial intelligence, expert systems, knowledge-based systems, etc.) into their requirements and design. This presentation will describe a view of systems engineering which successfully addresses several aspects of this complex problem: design of large scale systems, design with requirements that are so complex they only completely unfold during the development of a baseline system and even then continue to evolve throughout the system's life cycle, design that involves the incorporation of new technologies, and design and development that takes place with many players in a distributed manner yet can be easily integrated to meet a single view of the requirements. The first generation of this methodology was developed and evolved jointly by ISX and the Lockheed Aeronautical Systems Company over the past five years on the Defense Advanced Research Projects Agency/Air Force Pilot's Associate Program, one of the largest, most complex, and most successful intelligent systems constructed to date. As the methodology has evolved it has also been applied successfully to a number of other projects. Some of the lessons learned from this experience may be applicable to Freedom.

    The ignition experiment ZEPHYR will need tritium as an essential component of the fuel. The ZEPHYR Tritium Systems are designed as to recycle the fuel directly at the experiment. An amount of tritium, which is significantly below the total throughput, for example 10 5 Ci will be stored in uranium getters and introduced into the torus by a specially designed injection system. The torus vacuum system operates with tritium-tight turbomolecular pumps and multi-stage roots pumps in order to extract and store the spent fuel in intermediate storage tanks at atmospheric pressure. A second high vacuum system, similar in design, serves as to evacuate the huge containments of the neutral injection system. The spent fuel will be purified and subsequently processed by an isotope separation system in which the species D 2 , DT and T 2 will be recovered for further use. This isotope separation will be achieved by a preparative gaschromatographic process. All components of the tritium systems will be installed within gloveboxes which are located in a special tritium handling room. The atmospheres of the gloveboxes and of the tritium rooms are controlled by a tritium monitor system. In the case of a tritium release - during normal operation as well as during an accident - these atmospheres become processed by efficient tritium absorption systems. All ZEPHYR tritium handling systems are designed as to minimize the quantity of tritium released to the environment, so that the stringent German laws on radiological protection are satisfied.

    The data acquisition system of the Mega-Amp Spherical Tokamak (MAST) presently collects up to 400 MB of data in about 3000 data items per shot, and subsequent fast growth is expected. Since the start of MAST operations (in 1999) the system has changed dramatically. Though we continue to use legacy CAMAC hardware, newer VME, PCI, and PXI based sub-systems collect most of the data now. All legacy software has been redesigned and new software has been developed. Last year a major system improvement was made-replacement of the message distribution system. The new message system provides easy connection of any sub-system independently of its platform and serves as a framework for many new applications. A new data acquisition controller provides full control of common sub-systems, central error logging, and data acquisition alarms for the MAST plant. A number of new sub-systems using Linux and Windows OSs on VME, PCI, and PXI platforms have been developed. A new PXI unit has been designed as a base sub-system accommodating any type of data acquisition and control devices. Several web applications for the real-time MAST monitoring and data presentation have been developed

  12. Managing hybrid marketing systems.

    As competition increases and costs become critical, companies that once went to market only one way are adding new channels and using new methods - creating hybrid marketing systems. These hybrid marketing systems hold the promise of greater coverage and reduced costs. But they are also hard to manage; they inevitably raise questions of conflict and control: conflict because marketing units compete for customers; control because new indirect channels are less subject to management authority. Hard as they are to manage, however, hybrid marketing systems promise to become the dominant design, replacing the "purebred" channel strategy in all kinds of businesses. The trick to managing the hybrid is to analyze tasks and channels within and across a marketing system. A map - the hybrid grid - can help managers make sense of their hybrid system. What the chart reveals is that channels are not the basic building blocks of a marketing system; marketing tasks are. The hybrid grid forces managers to consider various combinations of channels and tasks that will optimize both cost and coverage. Managing conflict is also an important element of a successful hybrid system. Managers should first acknowledge the inevitability of conflict. Then they should move to bound it by creating guidelines that spell out which customers to serve through which methods. Finally, a marketing and sales productivity (MSP) system, consisting of a central marketing database, can act as the central nervous system of a hybrid marketing system, helping managers create customized channels and service for specific customer segments.

  13. Modeling Sustainable Food Systems.

    The processes underlying environmental, economic, and social unsustainability derive in part from the food system. Building sustainable food systems has become a predominating endeavor aiming to redirect our food systems and policies towards better-adjusted goals and improved societal welfare. Food systems are complex social-ecological systems involving multiple interactions between human and natural components. Policy needs to encourage public perception of humanity and nature as interdependent and interacting. The systemic nature of these interdependencies and interactions calls for systems approaches and integrated assessment tools. Identifying and modeling the intrinsic properties of the food system that will ensure its essential outcomes are maintained or enhanced over time and across generations, will help organizations and governmental institutions to track progress towards sustainability, and set policies that encourage positive transformations. This paper proposes a conceptual model that articulates crucial vulnerability and resilience factors to global environmental and socio-economic changes, postulating specific food and nutrition security issues as priority outcomes of food systems. By acknowledging the systemic nature of sustainability, this approach allows consideration of causal factor dynamics. In a stepwise approach, a logical application is schematized for three Mediterranean countries, namely Spain, France, and Italy.

  14. A national control system

    International Nuclear Information System (INIS)

    Larsson, A.

    1975-01-01

    An effective control of nuclear fissionable material is dependent on three different kinds of control, the industry - laboratory management, a national control system and an international safeguards system. The national systems of control differ greatly between various industrialized countries. Two principal reasons for fact can be mentioned. The type and the amounts for nuclear material may be different depending upon the stage of development of the nuclear industry in the country in question. Another reason may be that the country may wish to establish a very elaborate national system of control in order to minimize the IAEA control as much as possible. The two safeguards agreements between the Agency and Sweden on one hand and the Agency and Japan on the other hand can serve as examples for the understanding of the latitude of the IAEA safeguards system under NPT due to the influence of the national control system. If it thus is apparent that the national control system is strongly interrelated to the international safeguards system it is equally influenced by the control and accountancy systems which exist at the nuclear plants and development laboratories. A detailed study of national control systems and their relations to plant management control would fall outside the scope of this article. Some important features will however be examined. (author)

    Electrical utility distribution systems are in the middle of an unprecedented technological revolution in planning, design, maintenance and operation. The prime movers of the revolution are the major economic shifts that affect decision making. The major economic influence on the revolution is the cost of losses (technical and nontechnical). The vehicle of the revolution is the computer, which enables decision makers to examine alternatives in greater depth and detail than their predecessors could. The more important elements of the technological revolution are: system planning, computers, load forecasting, analytical systems (primary systems, transformers and secondary systems), system losses and coming technology. The paper is directed towards the rather unique problems encountered by engineers of utilities in developing countries - problems that are being solved through high technology, such as the recent World Bank-financed engineering computer system for Sri Lanka. This system includes a DEC computer, digitizer, plotter and engineering software to model the distribution system via a digitizer, analyse the system and plot single-line diagrams.

    Asteroids and other Small Solar System Bodies (SSSBs) are currently of great scientific and even industrial interest. Asteroids exist as the permanent record of the formation of the Solar System and therefore hold many clues to its understanding as a whole, as well as insights into the formation of planetary bodies. Additionally, SSSBs are being investigated in the context of impact risks for the Earth, space situational awareness and their possible industrial exploitation (asteroid mining). In all these aspects, the knowledge of the geophysical characteristics of SSSB surface and internal structure are of great importance. Given their size, constitution, and the evidence that many SSSBs are not simple monoliths, these bodies should be studied and modelled as self-gravitating granular systems in general, or as granular systems in micro-gravity environments in particular contexts. As such, the study of the geophysical characteristics of SSSBs is a multi-disciplinary effort that lies at the crossroads between Granular Mechanics, Celestial Mechanics, Soil Mechanics, Aerospace Engineering and Computer Sciences.

    Most of the Dutch large rivers, canals and lakes are controlled by the Dutch water authorities. The main reasons concern safety, navigation and fresh water supply. Historically the separate water bodies have been controlled locally. For optimizating management of these water systems an integrated approach was required. Presented is a platform which integrates data from all control objects for monitoring and control purposes. The Operational Management System for Regulated Water Systems (IWP) is an implementation of Delft-FEWS which supports operational control of water systems and actively gives advice. One of the main characteristics of IWP is that is real-time collects, transforms and presents different types of data, which all add to the operational water management. Next to that, hydrodynamic models and intelligent decision support tools are added to support the water managers during their daily control activities. An important advantage of IWP is that it uses the Delft-FEWS framework, therefore processes like central data collection, transformations, data processing and presentation are simply configured. At all control locations the same information is readily available. The operational water management itself gains from this information, but it can also contribute to cost efficiency (no unnecessary pumping), better use of available storage and advise during (water polution) calamities.
