    This system enables a driver to park the car at a predetermined spot without the driver seeing the outside scene. The system shows on a driver seat display the steps that the driver is to follow and thereby supports the driver when visibility is poor, when the parking space is difficult to approach, when the driver is a novice, or when the driver is aged. The system ensures accurate positioning of the car by showing the steering direction and angle, the car speed, and the force of braking to the driver. For this purpose, the system knows the absolute car position by the use of an RFID (Radio Frequency Identification) tag which is a kind of IC (Integrated Circuit) card and D-GPS (Differential-Global Positioning System), grasps the relative car position by the use of a gyroscope, and collects data from plural sensors, which are complementary to each other, such as a car-speed sensor and a steering sensor.

    Outlined herein are characteristics of solar radiation permeation in lean-to greenhouses provided with photovoltaic (PV) arrays on part of their roofs, and estimated quantities of power generated by the PV systems for different districts, seasons and cell areas. Three types of PV systems were followed; system 1: single-crystalline silicon, system 2: amorphous silicon, monolithically combined with the roof, and system 3: film-shape amorphous silicon. Annual quantity of power generated by these systems tends to increase as latitude decreases. They show an annual energy conversion efficiency of 10.3, 5.1 and 2.1%, respectively. Efficiency is unaffected by direction of the building on which the PV system is installed at low latitudes, as long as it is within {+-} 30deg around the east-west direction. At high latitudes, it is preferably in the east-west direction. For the PV system covering 30% of the roof area at a north latitude of 35deg, light received by plants in the greenhouse is fairly unaffected by the system throughout the year. These systems show a yearly solar energy utilization efficiency of 49 to 59, 46 to 55 and 44 to 53%, respectively, when they cover 60% of the roof area. 5 refs., 6 figs, 2 tabs.

In a test conducted in the presence of gas of 0-10ppm concentration, the prototype transmits signals that indicate excellent linearity and responsiveness. In the research and development of a probe for measuring electronic devices, efforts are made to put to practical use an IC (integrated circuit) probe of 40{mu}m pitch times 400 arrays, and specifications to develop for the probe are defined. A tentatively built cantilever structure shows values that justify its practical application. In the research and development of an IMI electronic circuit, a prototype No. 1 of a system for processing and transmitting sensor signals by radio is manufactured, which operates on the carrier frequency of 2.4GHz and sampling frequency of 4kHz. The prototype performs to achieve the goal. (NEDO)

    This paper describes the research result on the conceptual design of the total system for the WE-NET project in 1996. Basic conditions are as follows: solid polymer water electrolysis, hydrogen combustion turbine power generation, hydrogen transport/storage through ammonia medium, power generation scale of 1000-4000MW (2-5 yen/kWh), and transport distance of 5000-20000km between supply and consumption places. The system efficiency was estimated to be 68% and 23% at an ammonia arrival time and power sending end, respectively, and it was dependent on a transport distance, while no power generation scale. The power cost was estimated to be 7 yen/Mcal and 33 yen/kWh, respectively. The system efficiency at a sending end was lower by 15% and 2% than that of the liquid hydrogen and methanol system, while the power cost was higher by 0 and 8 yen/kWh, respectively. It was necessary for loss reduction of this ammonia system to develop a new high-efficiency ammonia synthesis process, and hydrogen separation (decomposition/refining) process. 80 figs., 52 tabs.

    The evacuation-support system is under development for not only the aged bedridden persons but also the persons disabled in exercising movement to excrete by themselves. When the person lying on his bed is going to excrete, his sequence of actions to be taken is to sit down on his bed, walk to the toilet, sit on it, simultaneously take off his clothes and excrete. After the excretion, the above actions are reversely taken as for as he lies on his bed. Researches are being made into the mechanical system which partially or entirely supports the above five necessary actions. The system structuring can depend upon the following five types of disabled persons` residual function: difficulty in sitting or moving without help. Paralyzed lower extremities and partially impaired upper extremities. Ability to walk with functional assistance. Ability to stand up with support but walk unstably. Ability to walk, leaning on and along the railing. In the present project, its three constituent elements are being developed which are the multi-functional bed internally equipped with transferring/riding/mounting apparatus, transfer support apparatus and multi-function portable toilet. The development of the present system is expected to be followed by that of the self-supporting excretion system which will be proper for Japanese houses. 3 figs., 1 tab.

    Since disabled persons increase with a progress of an aging society, while a care power decreases with a decrease in birth rate, development and practical use of the welfare equipment contributing to self-support of aged and handicapped persons, reduction of doctors' or therapists' burdens, and as a result, reduction of medical care costs are desirable. Among them, R and D and practical use are expected of the advanced welfare equipment and system based on human engineering technology contributing to improvement of lives of aged and handicapped persons, and support of nurses and cares of disabled persons. In fiscal 1998, on both human friendly care support intelligent equipment and home welfare equipment system, 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. For the former, 'heart disease diagnosis and treatment total support system,' and for the latter, 'body function rehabilitation support system' were surveyed. (NEDO)

    In this paper, to evaluate the hydrogen production cost per unit volume, system optimization of solar hydrogen energy system is discussed. Based on the simulation of the I-V characteristics of amorphous Si (a-Si) photovoltaic array, the working point between the array and hydrogen generator was determined. The cost ratio of each design point was calculated. The optimum design points were 500 W/m{sup 2} for the single crystal Si system, and 600 W/m{sup 2} for the a-Si system. When the rating capacity of design point was constant, almost constant cost ratio was obtained independent of the type of photovoltaic cells. It was found that the photovoltaic cells can be fabricated in about 15% lower cost at maximum. It was also found that the optimum design point sifts to the lower insolation site due to reduction of the photovoltaic cell cost. Since the annual hydrogen generation quantity does not depend on the type of photovoltaic cells under the constant rating capacity of design point, hydrogen can be produced in lower cost by using photovoltaic cell of lower cost. 5 refs., 10 figs., 5 tabs.

    Under the hydrogen-utilizing international clean energy system technology project WE-NET (World Energy NET Work) in fiscal 1998, researches and studies were conducted to clearly define safety designs and to improve on accident-and-safety analyses. In relation with system safety design, investigations continued into Japanese and foreign manuals and regulations about the handling of hydrogen and its peripherals, and safe design guidelines (draft) were compiled. Anomalies and accidents supposed to be typical of each of the systems concerned were investigated. As for accident-and-safety analyses, incorporation of a turbulence model was studied in relation to models representing the leak, evaporation, and diffusion of liquid hydrogen, and improvement was achieved when the scope of evaluation was enlarged concerning the hydrogen detonation model. The integration of the two models was discussed for the due evaluation of a series of processes of liquid hydrogen leak, evaporation, diffusion, and detonation. Calculation was performed for two assumed accidents, and the results were found to justify the integration of the two models. (NEDO)

    For a coordinated task to be accomplished in an organization, documents, charts, and data produced by plural workers need to be shared by the plural workers. This information sharing setup will function more effectively when the meanings and purposes of documents, etc., are arranged in good order relative to the other documents and when they are managed as a group of documents organically linked with each other and properly updated as the task approaches completion. In the self-evolving databases proposed so far, five types of document links representing the relations between documents are automatically generated and the documents are unifiedly managed for the documents yielded by coordinated work to be arranged in a proper order. A procedure for automatically generating document links are established on the basis of information received from the document retrieval system and Lotus Notes application. In a self-evolving database, the document on either side of a link is apt to be lost due to users` moving or deleting documents. An automatic procedure is developed in this report which will enable such document links to correctly restore themselves without loss of semantic relations. 12 refs., 11 figs., 3 tabs.

    To suppress the emission of environmental pollutants from coal utilization in China and to contribute to stable security of Japan`s energy, demonstration of clean coal technology and consolidation of diffusion base to be introduced into China have been promoted. Demonstration program for diffusing simplified desulfurizers has been promoted. For accelerating the achievement, experts of desulfurizers were delegated to Weifang Chemical Industry Works, to support the program. Exhaust gas is introduced from boiler via water spray dust remover, suction fan and centralized stack into absorption tower of the simplified wet-type desulfurizer. In the ascending process, the exhaust gas contacts with absorbent, to remove SO2 and dust. The absorbent is blasted up through the spray nozzle. The absorbent is oxidized by the air into sulfate ion in the liquid chamber at the lower part of tower, and neutralized by hydrated lime to form gypsum. Through the continuous operation for two years, understandings were remarkably increased. However, good treatment of the tax system is required for further diffusion. Though there are no problems for ordinary start and stop, emergency operation is insufficient. There are some problems in the maintenance due to the delay of finding failures. 16 figs., 1 tab.

    Purpose of the project is to develop a transfer aid system for the elderly who need assistance in moving from a bed or a chair. It can make up insufficiency of assistant persons and can help to comfortably move the elderly. It has the highest demand in rehabilitation centers or hospitals. We have been designing an actuator using a metal hydride alloy for more than ten years and have confirmed that the actuator is very useful for developing the transfer. Furthermore, we have designed the transfer from a view point of human interfaces. This research was done under the above background. 1. We studied a comfortable posture for the elderly at an initial phase of standing to design the optimal knee pad using a life-size model of a transfer. Especially, we managed to lighten the burden imposed on the elderly by referring electromyographic signals at lower limbs and ground reaction forces. 2. Since the tactile sensation of the bottom of elderly person's foot gets dull, we designed a foot stage to prevent the elderly from the dull. 3. We determined the optimal mixture rate of a metal hydride alloy and developed an elastic bellows in order to design the actuator used for the transfer aid. 4. We determined the optimal compliance to prevent the elderly from a mechanical shock and designed a mechanism so that the transfer aid can work well. 5. Based on the above results, we developed the transfer aid using the metal hydride actuator. It was ascertained that it can lift a elderly person with 80kg weight by using only 40g alloy. Furthermore, it is proved that the transfer is not heavy (about 20g weight), small, silent, and moves smoothly by a battery on the market. (NEDO)

When CE aiding by means of a computer is considered, it is important to discuss a method for information management not only for `utilization of product models`, but also for `maintaining consistency between items of product information` and `concurrent utilization and production of product information` in concurrent designs. For the CE aided information management, utilization and production of the product information is effective if restrictive relationship between items of product information, and design functions are made clear. Definitions were given on the restrictive relationship between items of product information and `restrictive relationship information` that has `decision/provisional decision`, `date and time`, `designer` and `design functions`. Furthermore, `comprehensive relationship between items of product information` that can be produced from the restrictive relationship information was defined as a `restrictive network`. Utilizing the restrictive relationship between items of product information for CE aiding is effective. 9 refs., 14 figs.

    Conceptual design was made on a database system as part of the comprehensive surveys of nationwide geothermal resources. Underground hot water in depths of several kilometers close to the ground surface is a utilizable geothermal energy. Exploration using the ground surface survey is much less expensive than the test drilling survey, but has greater error in estimation because of being an indirect method. However, integrating data by freely using a number of exploration methods can improve the accuracy of estimation on the whole. In performing the conceptual design of a geothermal resource information system, the functions of this large scale database were used as the framework. Further data collection, distribution and interactive type man-machine communication, modeling, and environment surveillance functions were incorporated. Considerations were also given on further diversified utilization patterns and on support to users in remote areas and end users. What is important in designing the system is that constituting elements of hardware and software should function while being combined organically as one system, rather than the elements work independently. In addition, sufficient expandability and flexibility are indispensable. (NEDO)

    This paper reports the study results on the standard weather data necessary for simulation of PV power generation systems in fiscal 1994. In the study on the selection criterion of the standard weather data from the viewpoint of PV power generation systems, three typical years are used; a year with average solar radiation, and two years with extremely less and more solar radiation for safe simulation. The standard weather data are arranged for output calculation of PV power generation systems by selecting the most typical year based on long-term observation data. The data to be arranged are as follows; total, direct and scattered solar radiations incident upon a horizontal surface, solar radiation upon a slope surface, sunshine duration, air temperature, wind direction, wind velocity, amount of precipitation, and snow depth. For arrangement of the nationwide standard weather data, estimation of total solar radiation is necessary based on sunshine duration data observed by all weather bureaus. In this study, the estimation model was developed of the total solar radiation integrated with time from rotary pyrheliometer data. 5 figs.

    To construct an advanced operation and management system for utility telecommunications management network (TMN), this paper proposes a modeling method of managed objects (MOs) required for managing and managed systems, such as an asynchronous transmission mode (ATM) exchanger. Flexible line setting and path switching control are required for the advanced TMN, which must cope with the extension and modification of functions, flexibly. Assignment of roles of managing sides and managed sides was determined. Then, structures of objects such as facilities and logic data, and their interaction were modeled. Common management functions and objects of each function were classified. Based on the TMN standard and MOs of the existing design peculiar to utility, new MOs peculiar to utility were defined in response to the models. The existing MOs can be effectively utilized, and the optimum MOs to be incorporated can be expected. The MOs peculiar to utility are added to the common specification of electric power industry. Since they can be reused for the extension and modification of functions, the cost can be reduced. The MOs applicable to path switching control of utility were designed as a trial. 9 refs., 16 figs., 10 tabs.

    This paper describes a hydrogen transportation system utilizing metal hydrides. For a storage method for moving, metal hydrides having high hydrogen containing performance like Mg-based hydrides would have high portability, less weight disadvantage, and high economic performance. In the fixed location storage, metal hydrides are superior in safety and maintenance cost to the conventional high-pressure gas holder and liquefied hydrogen storage. Because of their high dependence on equilibrium pressure and temperature, the significance of development thereof is large as the source of high-pressure hydrogen generation and motive force. More effective utilization of low-level heat, and separation and refining of hydrogen may also be expected. With regard to fuel supply for hydrogen fueled automobiles, metal hydrides are better in safety and total energy cost than liquefied hydrogen, but have a number of disadvantageous points in weight demerit. Eliminating the weight demerit would be the central issue of the development. Accompanying the development of hydrogen fueled automobiles, there are a number of technological elements to be developed on fuel supply system, such as storage, moving and transportation in hydrogen manufacturing sites, and filling and storage at using sites. Arranging the related infrastructures would be the issue. (NEDO)

    This paper reports the wind power development field test project in the off-shore park in Daitocho Town in Shizuoka Prefecture. The annual average wind velocity was 4.2 m/s (at height of 20 m above the ground), where the facility utilization rates for 300 and 500 kW class plants were 15.1 and 16.7%, respectively. Both of the annual average wind velocity and the facility utilization rate do not meet the criteria established by NEDO. Although the location is adjacent to the Natural Park, there is no restricting condition for installation. The substation to which system linkage is to be performed is the Daito substation 3 km north of the planned location. The major load is the Daito Spa in the park facility. Ground bed at depth of 5 m will be used as the windmill foundation supporting bed. There is little electromagnetic wave hazard. The location is 380 m away from the nearest residential house, presenting no windmill noise problem. The amount of power to be generated was assumed 281,000 kWh. Specifications for nine models of 300-kW class windmills that can be introduced into Japan were discussed to select a model. The project cost was calculated to be 128.5 million yen. The construction cost will be 428,000 yen and the power generation cost 38.1 yen/kWh. Its economy is poor when the current unit price for surplus power purchase is considered, but the effect of enlightenment may be expected. (NEDO)

    The control system for keeping the fixed-point of ships against disturbance was designed by applying an ILQ (Inverse Linear Quadratic) control (possible to specify the response of controlled systems with time constant) theory, to study the effect of different time constants as design parameter on a fixed-point keeping performance. It was assumed that the controlled ship is equipped with two bow thrusters and one stern thruster of 30ton in output to generate a control force. For fixed-point keeping control, the state equation was derived to slave the controlled system to a target input. The ILQ design method uses the result of the inverse problem of optimum regulators. For designing control systems by using the ILQ control theory, the smallest time constant should be selected according to the most severe disturbance condition considering the response performance of controllers, to achieve fixed-point keeping of ships. In fixed-point keeping, it is also essential to put the initial position as close as possible to the target point. 2 refs., 6 figs., 2 tabs.

    Actualities of exhaust heat and demand for heat in the area are investigated on the result of which a wide-area energy utilization network system will be built. In fiscal 1998, further questionnaires are distributed in addition to last fiscal year's, and door-to-door visits are made on leading factories representing 10 types of industries. The result of data analysis places the nationwide total of exhaust heat at 320,000 Tcal/year including heat generated by electric power generation. When it is so defined that usable heat be above 150 degrees C for exhaust gas, above 40 degrees C for hot water, and above 200 degrees for solids, the total will be reduced to 230,000 Tcal/year. Cleaning plants (plants that treat refuse or sewage) as the sources of exhaust heat besides the factories are investigated for the amount of heat they discharge, and then it is found that the amount of heat they discharge is the fourth largest following electric power plants, iron and steel mills, and chemical plants. It is also found that most of their exhaust heat is of good quality because it is latent in steam or hot water. It is acknowledged, partly because many of such plants are situated relatively near to the urban district, that their role is important when studies are made on the utilization of exhaust heat.

    As a research on systematizing ECO and ENERGY cities, surveys and analyses were performed on the actual state of introducing district heat supply systems utilizing difference waste heats including factory waste heat. Waste heat from electric power generation is utilized for district heat supply in Japan at 122 points or about 20% of the district heat supply points in operation as of March 1998. The number is in the increasing trend in recent years, and the future potential of its introduction can be said high as the history thereof is still short. Its introduction form is accounted mostly for by building cogeneration or plant cogeneration. Back-up facilities for the case when waste heat supply stops because of regular facility checks are provided by the heat supply business operators, which impede the economy of the system. In the U.S., the Public Utility Regulatory Policy act motivated installation of cogeneration and off-peak power generation systems for district heat supply. Technical maps (for waste heat sources and different waste heat utilization systems) were prepared based on the surveys to discuss the future measures. (NEDO)

    For collecting solar radiation data necessary for the prediction of power to be outputted by photovoltaic power systems in Japan, detailed experiments and observations were conducted with an emphasis placed on the amount of solar radiation on a slope facing north and on the amount of solar radiation broken down by wavelength. Models were analyzed, and the fiscal 1999 results were compiled. In the validation of a model of solar radiation on an inclined surface, a review was conducted using the 1-year data observed at the Takasaki station for all directions, including solar radiation on the slope facing north, and the validity of the model was confirmed. As for the validation of a model for estimating solar radiation by duration of sunshine, it was examined for accuracy using the same data, and was found to be fairly high in accuracy. For the maintenance of solar radiation data for each wavelength, continuous observation was conducted for each wavelength of solar radiation at the Takasaki station using a multi-filter spectroradiometer, and a technique was established to determine spectral distribution using the observed data. Moreover, continuous observation of global diffused solar radiance was conducted using a sky scanner at the said station and solar cell power generation characteristics was continuously monitored.

    With the purpose of developing high strength and high-anticorrosive aluminum-based material through microstructure control, R and D was conducted, with fiscal 2000 results compiled. In the research of grain refinement mechanism, molten metal rolled stock was experimentally produced in which Mg content was varied 0-2.5 mass % with Al-2.5 mass % Mn as its base. As a result, a microstructure with an average grain size of about 3 {mu}m was obtained by processing the alloy through homogenization at 550 degrees C, cold rolling by 91% and the final treatment at 350 degrees C without Mg addition. Addition of Mg increased square grain boundaries in the microstructure, raising proof stress to about 180 MPa in Al-2.5%Mn-2.5%Mg alloy. In the research of development of the machining process, a rapid heating process was performed on a typical aluminum alloy, with the effect examined, by an alloy system or a plate thickness, on the electric power used and on the temperature reached. A rapidly heated aluminum alloy plate turned to have a microstructure with equi-axed grains of a uniform size, compared with a salt bath processed material heated at the same temperature. (NEDO)

    To verify the clean coal technology to be diffused in China and consolidate its diffusion basis, demonstration project of circulating fluidized bed boiler was conducted through the cooperation with China which is positive in its introduction. This report describes its characteristics. Coal and limestone are supplied in a lower part of combustion chamber, and are mixed with circulating ash by fluidized air for combustion. Densely fluidized bed the same as the bubbling fluidized bed is formed in the lower part of combustion chamber, which provides excellent stability in ignition and combustion. Particles including ash, char and limestone formed during the combustion are discharged into the cyclone through the convection heat transfer part at the outlet of combustion chamber with the combustion gas flow. Since the gas temperature is lowered to 400 to 500degC at the convection heat transfer part, troubles of the ash circulating system can be prevented. The combustion gas separated from ash at the cyclone is discharged through the heat exchanger and precipitator, and the collected ash is returned to the lower part of combustion chamber. In FY 1997, design, fabrication, procurement/inspection, field survey/meeting, survey of visitors/meeting, and education were carried out. 4 figs., 4 tabs.

    The capacity and performance of the existing system that recovers the overall heating and cooling exhaust heat completely into a seasonal storage tank and the system that discharges the exhaust heat slightly to the outside and recovers it partially were compared and investigated. The system uses a central single-duct discharge system as an air-conditioning system. A heat pump and a flat-plate solar collector installed on the roof of a building are used as the heat source. The seasonal storage tank in the ground just under the building is a cylindrical water tank of 5 m deep with the concrete used as body. The upper surface of a storage tank is heat-insulated by a stylo-platform of 200 mm, and the lower side surface by a stylo-platform of 100 mm. Calculation when the difference in temperature used in a seasonal storage tank is set to 35{degree}C and 25{degree}C was performed for the system that has two control methods. The overall exhaust heat recovery system is almost the same in energy performance as the partial exhaust heat recovery system. The partial exhaust heat recovery system is more advantageous on the economic side. 4 refs., 6 figs., 3 tabs.

    The two-stage compression cascade heating heat pump cycle was devised for hot water supply in business use such as hotel and store use which allows hot water supply less in primary energy consumption than gas boilers, and higher in temperature than conventional heat pumps. This cycle heats water in cascade manner by two-stage compression using two compressors in both low- and high-stage refrigerant circuits, and two condensers different in condensation temperature (intermediate heat exchanger and condenser) to achieve higher hot water temperature and higher COP. For cost reduction, the new system design method was established which is possible to cope with conventional compressors such as screw and scroll ones with different theoretical suction volume for every one. System design parameters such as thermal output and COP of hot water supply were largely affected by theoretical suction volume ratio of low- and high-stage compressors dependent on combination of the compressors, and refrigerant condensing temperature in an intermediate heat exchanger as proper parameter. 4 refs., 17 figs., 13 tabs.

    Computer chemistry was investigationally studied. The advance of theoretical chemistry is indispensable to the design of materials, and the theory and high speed computational method are expected which can simulate the real system with more accuracy. It is basic to simulate structures and physical properties of structural molecules and the aggregate, but the meso region, the intermedium region between structural molecules and the aggregate, has became regarded as important. Rough visualization models in high polymer materials and the progress of computational software/hardware of quantum chemistry/molecular dynamics such as catalyst become necessary. Seamless zooming is proposed as a concept of the software which simulates materials from micro/macro/meso viewpoints. Moreover, to make the most of computer chemistry, an integrated system is necessary which generally handles computational software, database, etc. For the development of software, indispensable is the demonstrative verification by a combination of experiments and researchers. Under a commission from NEDO, the investigational research was conducted as a leading study during fiscal 1996 and 1997 to view the course of the research. 17 refs., 37 figs., 5 tabs.

    An active use of the natural materials replaced the petroleum chemical products and an attempt for a development of the organism imitation materials are not limited only on the surfactants, but become a great trend also widely over the dyestuff, plastics material, food, cosmetics, agricultural chemicals and so forth. In addition, an institution of the recognition system for an 'eco-mark' is done, and a development of the environment conformity materials (eco-material) is advanced. In Japan since around 1950, a practical application and a research and development of new surfactants have been rapidly progressed making the derivatives originated in a petroleum chemistry as an axis. In this paper, including a viewpoint of the ecotechnology, a chemical structure and function of the surfactant being derived from the organisms, a molecule design and attempt for functional material making of the biomimetic surfactants are described. The author considers the biomimetic surfactants as one of the approaches to develop a new functional surfactant as the new raw materials, and is performing a development of the admixtures for improving a defect the soap has and so forth. 80 refs., 3 figs., 5 tabs.

    Introduced herein is the construction of Yuge-Ohashi Bridge, a 325-meter long three-span cable-stayed structure. Each tower is provided with deflectors to prevent galloping vibration that the bridge may experience after completion. Because it was afraid that the towers during the erection process would experience at the base sections a bend that would be greater than their withstand strength, vibration dampers TMDs (Tuned Mass Dampers) were installed. To enable the spars to withstand strong wind after completion, wing-type flaps were arranged on their sides. To damp vibration during the spar cantilever erection process, TMDs of the cantilever type were provided capable of responding to the vertical direction vibration, for which weights were caused to travel along the arms for tuning. To prevent the top-stage cables from rain caused vibration, U-shape grooves were provided. To prevent the intermediate-stage cables from rain caused vibration, high-attenuation rubber dampers were installed. A side span spar and a tower were installed en bloc by FC (Floating Crane) boats, and the central span spar was installed by cantilever erection. Thanks to the fuzzy control-aided accuracy management system, cable adjustment was efficiently accomplished and the accuracy fell within the target value range. 4 refs., 5 figs.

    The Daini-Chikumagawa bridge, having spans of 134m {times} 2 which is the largest in Japan as the concrete railroad, is a prestressed concrete (PC) oblique cable-stayed bridge building on the Hokuriku Shinkansen express line which is constructing towards Nagano Olympic (Feb.1998). Regarding adoption of the oblique cable-stayed bridge for the railroad bridge, there are very few examples on a global scale and in Japan besides this bridge there is only one example (Omoto bridge (Iwate pref.), span = 85m). One H type tower (H = 65m from the surface of bridge) is erected at the center of the Chikuma river and then main girders are built at the front and rear of this tower. These main girders, being separated into 5m {times} 24 blocks per one side excepting surroundings of the tower, are fabricated as a three room box type PC block (total width 12.8m; height 3.0m) each on the river beach near the spot. These blocks are jointed from the tower side by the overhanging work using the constructing vehicles and are fixed with oblique materials (cables; two face hanging system) at intervals of 10m. 4 refs., 16 figs., 5 tabs.

    In order to improve the efficiency and quality of metal molding designs, Sony Corp. has adopted an injection molding simulation system since the first half of 1980s. Since, however, molding materials are thermal fluids, which transit their phase from liquid into solid, and boundary conditions will be changed in the middle of their cycles, their analyzing works are very difficult. Therefore, softwares in this field are still on the way to be developed. Since this corporation has joined to the Cornell Injection Molding Program (CIMP) project in Cornell University, they have added improvements on their programs to be supplied, and have used them with their own programs developed additionally based on transformation processes. They have carried out minimizing of shape of boss root and examining holding pressure control by this simulation system. Since actually input works for CAD process have been carried out by hand now, it takes a time a little, though, they have also considered to make it easy by automating for applications of the full model. 4 refs., 7 figs.

    The aim is to improve on hydrocarbon oxidation which is a difficult reaction (analogous to combustion and having potential for heat generation or explosion, with restrictions therefore imposed on reaction conditions) by use of a catalyst supporting porous membrane. The fiscal 1999-2000 results are stated. In this effort, the target reaction is promoted by a catalyst supported by a porous membrane while combustion is controlled by the said porous membrane that separates oxygen and hydrocarbon from each other. Such a design was not available since a catalyst supporting inorganic membrane withstanding so high a temperature was difficult to prepare. Recently, however, a porous membrane with its pores regulated to microstructural dimensions was developed. The activity of a Pd membrane catalyst is evaluated in view of the degree of oxidation of propylene, cyclohexene, and benzene. It is then found that hydrogen that has passed the Pd membrane participates in the reaction. In a propylene oxidation test using a membrane type Ag/Al{sub 2}O{sub 3} catalyst, it is found that acetone is generated and that oxygen after passing through the membrane participates in the reaction. Methods are studied for preparing a metal membrane in which the catalyst system comprises a catalyst supporting porous membrane and a Pd membrane. In the fabrication of metal membranes, a highly selective hydrogen permeable membrane is stably prepared by the thermal CVD (chemical vapor deposition) method. (NEDO)

    The Quiet Short Take-Off and Landing (QSTOL) Experimental Aircraft `ASKA` has been researched and developed by the National Aerospace Laboratory (NAL). The `ASKA` was based upon the airframe of the home produced C-1 tactical transport which was modified into the Upper Surface Blowing (USB) -powered high- lift STOL aircraft. The wing configuration, however, was not changed. Therefore, this Experimental Aircraft does not always have the optimum configuration of a USB-type aircraft. So the authors tried to improve the aerodynamic characteristics of the STOL Aircraft. This paper describes the investigations which have been conducted to improve the aerodynamic characteristics of a subsonic jet transport semi-span model with an Upper Surface Blown Flap system which has been newly designed using the NAL STOL-CAD program. The model had an 8.2{degree} swept wing of aspect ratio 10.0 and four turbofan engines with short USB nozzles. The tests were conducted in the NAL 2{times}2m Gust Wind Tunnel with closed section and results were obtained for several flap and slat deflections at jet momentum coefficients from 0 to 1.85. Compared with the aerodynamic characteristics of the `ASKA` model, we determined that the airframe weight can be reduced and the aerodynamic characteristics can be improved significantly. 14 refs., 44 figs.

    The composite panel with photovoltaic-thermo module becomes higher in energy-saving than the conventional air-conditioning system by the independent radiational heating and cooling effect obtained when the generating panel using a solar cell module is combined with the heating and cooling panel using a thermo-element module. The output of a solar cell module can be directly used because the solar cell module operates in AC. This paper reports the relation between the absorbed value and power consumption of the cooling panel, while paying attention to the cooling panel. The performance coefficient of the maximum absorbed value from an non-absorbing substance to a cooling panel is 2 to 3. Assume that the cooling panel during non-adiabatic operation is operated using a solar cell module of 800 W/m{sup 2} in solar intensity and 15% in conversion efficiency. The cooling-surface temperature difference is 12.12 K, and the maximum absorbed value of a non-absorbing substance to a cooling panel is 39.12 W/m{sup 2}. The absorbed value of the outer temperature to the cooling panel is 74.4 W/m{sup 2}, and each performance coefficient is 3.26 and 0.62. The absorbed value must be calculated for evaluation from the cooling-surface temperature difference measured directly from the cooling panel. 4 refs., 8 figs., 1 tab.

    In relation to the circulating fluidized bed boiler which reduces the amount of sulfur oxides emitted in coal utilization, a verification project was carried out on installation of the equipment and spread activity in China and the Philippines contributing to the control of environmental pollutant associated with coal utilization and the effective use of energy. At the Fanshan area, installed was a 10t/h internal circulating fluidized bed boiler. At the performance test, coal includes around 7% of impurities such as stone, and the impurities should be excluded continuously at the time of actual run. Therefore, the boiler efficiency had to be changed from 89.5% to 85.8%. Further, power generation facilities have not yet been finished, and the overall operation of boiler turbine has not been executed. At the Zibo area, a 30t/h external circulating fluidized bed boiler was installed. The boiler efficiency reached 86.1%, over the targeted value. At the Batangas area in the Philippines, a 10t/h internal circulating fluidized bed boiler was installed. The boiler efficiency reached 85.8%, over the designed value. About the coal produced in the Philippines, slagging was feared, but the combustion state was favorable. 82 figs., 21 tabs.

    The effort of fiscal 1997 at isolating the best way to introduce a relatively small amount of hydrogen into urban fuel economy was carried over to fiscal 1998. In the research of fiscal 1998, comparison was made between Tokyo and London in connection with hydrogen introduction, and a transition scenario was proposed for introducing hydrogen into Tokyo. Models were built for Tokyo and London, and studied. The result of this study was different from that obtained in the previous study, and places the two cities under similar conditions. The difference is attributed to the rapid progress in the development of the fuel cell and to the resultant reduction in cost. It is inferred that, in consideration of the transportation situation, the introduction of pure hydrogen will be the most cost-effective for both cities at least for some time to come. According to the revised data, natural gas may be procured in Tokyo as in London but the size of supply available in Tokyo is fairly smaller than that in London. Several transition scenarios covering the period up to 2025 were subjected to discussion. (NEDO)

    This project is aimed at development of automatic rotary table type digging apparatus capable of digging high-temperature beds of 3,000 to 5,000 m in depth, 400 degrees C and 500 kg/cm{sup 2}. The automatic excavation apparatus is designed based on the concept that the driller is separated from the running drawworks side for other works. However, it is operated manually in a traditional manner, when the bed for which it is to be used is under complex conditions, or when the bed properties require frequent changes in digging conditions with respect to bit load and speed of rotation. The apparatus works, when the bed is considered to be under essentially constant conditions at a fairly high depth, in such a way that a combination of bit load and speed of rotation is set by the driller, and the work line wound on the drawworks drum is let out to keep the bit load constant. It is equipped with, e.g., a controller, converter and brake operating device, detecting suspension load by the controller, when it increases, increasing speed of air motor after comparing the load with the reference level, and relaxing the brake, to keep the suspension load at the set level. When the suspension load decreases, on the other hand, the air motor is decelerated to tighten the brake. (NEDO)

    The pilot plant outputs 1000kWe. Under an automated operation program, 2 operators per shift take care of the whole plant (with one operator on patrol). Daily startup and stop is automatic in principle. The system stops its operation in principle when the computer is down, with accessories to be manually stopped. Warnings are dealt with all by the computer. A safety sequence is organized independent from the computer. The operators interfere with the system for the manipulation of subsystems and adjustment functions. With the plant in normal operation, the computer system logs data, monitors warnings, and the plant is under control of an analog control unit. For the activation of the automatic startup/stop function, the operators have to choose a mode of operation. The above-named document covers, furthermore, the data processing function of the automatic operating system, automatic startup/stop program, hardware, automatic startup/stop table, and a general flow chart describing the automatic startup/stop train.

    The documentation assumes a new type high speed ship, higher than 50kt in speed and heavier than 1000ton in dead weight, to require the ocean goingness, middle distance navigation and high speed transport. The present report dealed with how to discriminate a ship, navigating at a high speed on oceanic waves, in critical condition against the encountering waves. Navigating far distantly from the shore, the ship was generally made to positively utilize the information data from the geostationary metheorological satellite (GMS) to be applied as a support soft tool for the maritime system and other designs. As a result, the high speed ship on the quartering waves was numerically elucidated in critical condition against the encountering waves and simultaneously assumed in critical course upon discriminating the critical condition in a concretely designated oceanic area. It was shown that, if different Froude numbers are calculated and ordered of critical circular frequency, angle, wave period, etc. against the encountering, a dimensionally arbitrary ship is easily discriminatable in critical course in an arbitrary oceanic area by utilizing a GMS determination support tool. 12 refs., 14 figs., 2 tabs.

    The paper described the fiscal 1997 result of the study of scenarios for introducing hydrogen to the urban area. In the case of studying it in London, it was found that hythane (mixture of hydrogen into town gas) was effective, but in the case of doing in Tokyo, it was found that the scenario was undesirable because of the increasing infracost. Accordingly, another scenario was studied. It was assessed from the aspects of environmental advantages, infracosts, and potential advantageous values in urban areas associated with hydrogen utilization (hydrogen premium). It is most effective to use hydrogen as a fuel of transportation means from the aspect of environmental merits as the decrease in external cost. In Tokyo, the dependence upon electric power is large, and therefore it is attractive to introduce highly efficient fuel cells which enable the dispersed cogeneration using hydrogen. The value of hydrogen is determined by the avoidance of environmentally influential substances and the surplus generated output by fuel cells (substitution for the existing natural gas). When the high external cost can be assumed, the value of hydrogen becomes large. The paper also considered the arrangement of infrastructures in Tokyo. 187 refs., 14 figs., 18 tabs.

    This paper explains the application of the fuzzy theory to a design. A rational decision in design with only an objective logic requires conditions such that a set of selectable alternative plans and the results of executing them are known, and that a rule or a sequential relation exists to decide the order of preference of the alternative plans. In a case where the optimum anti-earthquake design was applied, for example, the seismic motion, subsoil and properties of materials or the like used to be treated stochastically and statistically as being of random nature. However, elements of uncertainty are actually involved other than the randomness, in consideration of cost effectiveness, safety and such. In the problems of anti-earthquake design by the fuzzy theory, the restrictive conditions are stipulated with a membership function respectively, such that the design earthquake motion is in a range larger than the maximum motion, and that the stress or displacement is each in the range smaller than the allowable stress or displacement of members; in addition, the weight is expressed to be the minimum as the objective function. 9 refs., 1 fig.

    The feasibility study was conducted on a model project in Vietnam, aimed at solving the environmental pollution problems resulting from use of coal by demonstrating and disseminating the Japan's environmental technologies in the Southeast Asian countries. The feasibility study was conducted for the Cua Ong Coal Preparation Enterprise, which has the largest coal preparation capacity in Vietnam and port facilities. It is treating raw coal from 10 coal mines for classification and preparation, and shipping coal of various types that meet the standards for domestic use and export. The survey results point out that unrecovered coal remains in waste water discharged from the coal preparation plants to pollute the sea area, and that quantity of the refuse increases because of the unrecovered coal it contains. The environmental technologies needed to introduce include modification to variable wave pattern type jigging separator, refuse height measuring instrument and automatic controller, circulating heavy medium gravimeter, highly functional settling pond, and flocculent facilities.

    This R and D are aimed at establishing technology to support the reservoir modeling work required for predicting the reservoir variation from the geological/geochemical side. The contents of the development are (1) establishment of the practical measuring system for core fracture system, and (2) establishment of new modeling support technology. In (1), as the core fraction system measuring system, the measurement of fluid inclusion homogenization temperature and melting point and laser Raman spectroscopy were applied to the Wasabizawa area to obtain the results. In (2), the R and D were conducted of a rapid age measuring method for altered rock/unaltered rock and an analytical method for fluid flow using trace chemical components of hydrothermal minerals. In the former, 3-D thermoluminescent intensity of the age-known quartz was measured. The TL age of weak altered rock of Kijiyama dacite in the Wasabizawa area was 320Ka, almost the same result as 320Ka already reported. In the latter, trace components of quartz were measured at each well, and changes in the depth direction were made clear. It was made clear that the variation of Na/K ratio is large around the lost circulation stratum. The geothermal fluid flow was made clear by the analysis of similarity of the intensity ratio. (NEDO)

    Observations are being made in Takasaki City, Gunma Prefecture on insolation, putting emphasis on the north side, and insolation by wavelengths to put insolation estimation model on the north side slope into order. This is an attempt to put into order by using the model the data for insolation on slope in all azimuth, taking the meteorological offices all over the country as the object. With regard to monthly average insolation, it was verified that the existing estimation model can be applied to the north slope in the Takasaki area, whereas trial calculations were performed on the average daily cumulative insolation by azimuth and inclination angle in the Takasaki observation points. As a result, it was made clear that the insolation onto north side roofs in Japan is about 70% of that on the south side. With respect to the time cumulative slope insolation, it was made clear that the Perez's cumulative model can be applied to the Takasaki area. Spectral distribution of global and scattered solar radiation was put into order by insolation to have verified that the stronger the global solar radiation intensity, the greater the occupation ratio of shorter waves increases, or in other words, the spectral distribution of the global insolation can be formulated. Sky distribution of radiation is being measured by means of measuring the sky scanning type radiation and luminance distribution. (NEDO)

    Surveyed are the roles of the government, important for environmental buildup for technological innovation. The U.S. research and development support programs are classed into contracts, grants, cooperative agreements, and CRADAs (Cooperative Research and Development Agreements). The government financially supports the first three, but not CRADA. It provides CRADA with manpower, facilities, and resources. The research and development (R-and-D) appropriation not for national defense in the U.S. fiscal 2000 budget is up 36% to $39.4 billion occupying 50.6% of the total R-and-D expense. The basic research appropriation is given the highest priority, enjoying an increase of 4.7% to $18.1 billion. In the U.S., taxation for R-and-D expenses is done in two ways. One is a research expense tax deduction system under which R-and-D expense is handled as a cost, a subject of deduction. The other is a research and experiment tax deduction system under which a certain percentage of R-and-D increment is free of taxation. NEDO's (New Energy and Industrial Technology Development Organization) system for national R-and-D projects is scheduled to change extensively upon reorganization of the government ministries and agencies in January, 2001. Under the circumstances, the current and future systems of the state supports for R-and-D are outlined, and the position of NEDO in them is clarified. The R-and-D systems of the entrusted businesses and the problems they contain are also described. (NEDO)

    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.

    The aim is to develop and popularize techniques relating to geological information such as thermal history. The efforts center about the application of a now-available core fracture measuring system to developed geothermal fields and about the development of new technologies. The measuring system is applied to some core cuttings collected from five boreholes in the Akinomiya district, Akita Prefecture, and the system is used for (1) the evaluation of homogenization temperatures of inclusions in the fluid, (2) the measurement of the points of melting from ice of inclusions in the fluid, and (3) the implementation of laser Raman spectroscopy. Under item (1), it is found that the minimum homogenization temperature of quartz phenocryst in the mother rock or of low-salinity fluid inclusion in a quartz vein is near the current subsurface temperature and that subsurface and reservoir temperatures may be known by evaluating their homogenization temperature. Under item (2), it is found that the NaCl equivalent salinity is distributed in the range of 0.0 to 25wt% and that, in this connection, there is difference between a fluid in a fluid flow and a fluid spurting as thermal water in the Akinomiya district. Under item (3), CO2, N{sub 2}, and CH{sub 4} are detected in most of the boreholes. Efforts are exerted to develop a hydrothermal fluid analyzing technique using a rapid rock dating method and traces of chemical ingredients in hydrothermal minerals. (NEDO)

    To evaluate geothermal reservoirs in the initial stage of development, to keep stable output in service operation, and to develop a technology effective for extraction from peripheral reservoirs, study was made on a reservoir variation prediction technique, in particular, a modeling support technique. This paper describes the result in fiscal 1997. Underground temperature estimation technique using homogenization temperatures of fluid inclusions among core fault system measurement systems was applied to Wasabizawa field. The effect of stretching is important to estimate reservoir temperatures, and use of a minimum homogenization temperature of fluid inclusions in quartz was suitable. Even in the case of no quartz in hydrothermal veins, measured data of quartz (secondary fluid inclusion) in parent rocks adjacent to hydrothermal veins well agreed with measured temperature data. The developmental possibility of a new modeling support technique was confirmed enough through collection of documents and information. Based on the result, measurement equipment suitable for R and D was selected, and a measurement system was established through preliminary experiments. 39 refs., 35 figs., 6 tabs.

    As a support study for the development of an entrained bed coal gasification power plant by a 200 t/d pilot plant, the dismantling study was made for gasifier facilities, desulfurization facilities, dedusting facilities at the existing 40 t/d testing facilities. In the results of the analysis of the specimens sampled from gasifier and peripheral facilities, the corrosion loss of thickness was great in carbon steel/low-alloy steel equipment, and the generation of intergranular corrosion/intergranular crack was recognized in stainless steel equipment. The loss of thickness caused by erosion was also recognized in carrier tubes, etc. As to the high-temperature dry desulfurization system, the damage was totally great, but the effect of taking measures for it was unclear because the loss of thickness by corrosion/abrasion had not been measured regularly. Relating to the high-temperature dry dedusting system, there used to be a lot of troubles from stress corrosion cracking and pitting corrosion, and the best measures for corrosion prevention were taken for each trouble. As to the Al thermal spraying, stabilized thermal treatment, shot-peening, etc., the excellent corrosion prevention effect was recognized on the austenite stainless steel. (NEDO)

    Discussions have been given on identification of actual status of exhaust gas emission during driving, starting, and idling of automobiles, on technologies to enhance fuel consumption and reduce exhaust gas emission, and on technologies to measure harmful substances. In the investigation of effects of environmental temperatures on evaporation gas, it was shown that fuel evaporation generated from the fuel tank increases as the average ambient temperature rises. In the investigation of effects of environmental temperatures on exhaust gas and fuel consumption, it was discovered that the effects of environmental temperatures on 10{center_dot}15 mode regulated exhaust gas differ depending on vehicles, and no definite difference due to combustion systems was recognized. Carbon monoxide and THC under the 11 mode regulation showed a trend to increase when the environmental temperature falls down. In the investigation of effects of fuel properties on exhaust gas, no definite difference due to combustion systems was recognized as a result of measurements using various types of gasoline having different distillation properties. In the investigation of analysis methods for harmful substances, development has been made on an analysis method mainly for 1-3 butadiene. (NEDO)

    As to the development of coal use hydrogen production technology, the paper made the test study on the improvement of gasifier use materials and evaluation of the characteristics, the evaluation test in the environment using the actual machine, etc., and the FY 1993 results were reported. The results of the study were as follows. Concerning the shaped refractory for gasifier hearth, it was found that high chromia base and picrochromite base refractory development materials had much more excellent coal slag resistance than other existing component-system materials. It was shown that the development materials began to deteriorate under the coal gasification environment at temperatures of about 1,500 degrees C or higher. As to the mullite ceramics, a possibility was shown of improving the slag permeation resistance by making the crystal grain coarse by long-time sintering. By the survey of the state of damage of the proposed materials (refractory and iridium) used in the operational environment of the pilot plant, the outlook for use limit was made clear. In the environment test using the actual machine on the proposed metal base alloy of the typical equipment of the pilot plant, the correspondence between the operational environment and material corrosion was made clear.

    With an objective of putting into practical use the wavelength multiplex recording system applied with the PHB phenomenon, research and development has been performed on material systems making high quality hole production possible at high sensitivity and high density. This paper summarizes the achievements in fiscal 1989. In the discussion of PHB materials, measurements were performed on the triple state of zinc, magnesium, copper and iron complexes of tetra-phenyl porphin and the triple state spectra by using the flash decomposition method in order to develop new photo-gate type material systems. Correlation was discovered between the free energy change in the reaction and the PHB reactivity from the result of the experiments, whereas important findings were obtained for designing the photo-gate type PHB material systems. In the discussion of the wavelength multiplex recording, an optical system was designed and fabricated to perform scanning and detection on sample surface by using laser beam squeezed to a diameter of 100 {mu} m. Discussions were given on the wavelength multiplex recording, position multiplex recording, and high-speed recording using this optical system. As a result, position multiplex holes were produced successfully by using the laser beam squeezed to a diameter of 100 {mu} m on four different positions on the sample surface, when the tetra phenylporphin derivative was used.

    The pressurized hydro-fluidized gasification method is such that coal is hydro-gasified under a pressure of 30kg/cm{sup 3} to produce a methane-rich calorie gas. This method is a combination of three independent processes, namely, (1) thermal cracking of coal, (2) hydrogasification of thermally decomposed product, and (3) water gasification for self-contained hydrogen, and is a continuous gasification method in which all processes are operated in a fluidized bed. In fiscal 1976, an operation technique was found in which conditions suitable for each reaction purpose were given to a detached thermal cracking furnace and hydrogasification furnace and in which continuous gasification was still maintained without an adverse effect between the two furnaces. This year, the continuous gasification test will be implemented successively, determining suitable operating conditions for the purpose of increasing methane concentration and improving gasification efficiency, and concurrently extracting device-related problems that impair the continuous operation. With the aim of obtaining a self-contained system for hydrogen, water gasification tests will be conducted, with the optimum conditions determined for the water gasification. An operation test will be carried out for an internal heat type control box, so that the functions under pressurization, durability and operation criteria will be determined. (NEDO)

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)

    This paper describes the precast segment construction of double-span continuous prestressed concrete (PC) box girder with a length of 93 m in the Soegawa Viaduct in Akita Prefecture. The match cast surface of the newly constructed segment is occasionally deformed into arch due to the temperature gradient generated by the hardening heat. To avoid this phenomenon, the minimum segment length more than one-sixth of the segment width of 11.2 m was determined. Compatible type internal/external cable method was adopted for the configuration of PC steel members in the main direction. In this method, steel members for PC were placed outside of concrete as well as inside of concrete. The yard for fabricating segments was made in the back area of abutment of the bridge. Segments fabricated using steel frames were brought in the yard using a crane and stocked. After the support construction, segments were constructed from No.1 segment in order. Since placing accuracy of the whole segments was affected by the placing of the standard segment, the accuracy was improved by the three-dimensional control using surveying equipment. After the construction of segments and tension of PC, the bridge is to be completed in September, 1997. 3 refs., 21 figs., 4 tabs.

    Through characteristics and examples of urban model, the present paper explains how the urban plan and design are conceived. It also does the recent trend of scenic arrangement in Japan. The progressionists base the urban model on the rationalism. They condition the urban space to be hygienic, functional, regulatory, geometric and orderly, which means the negation of cultural scenery with stores and houses on streets. Such a model is applied to the urban development in Japan. The culturists aim at an urban model characterized by the small-scale, intensive, organic and asymmetric urban space. Its scenery is cultural, local and organic. Its examples are given by British garden cities. Aiming at an urban model descended from the culturism, the townscape school plans the urban arrangement based on the individual experience and not the enlightening position. They commit a fault by disregarding the problem for the urban entirety and losing its philosophy. In Japan, the scenery is being built up through the preservation of historic townscape, scenic arrangement of stores and houses on streets, and planning of the park. 11 refs., 4 figs.

    Minokawai power station is a plant with low head and large water quantity (output: 23.4MW) that utilizes Imawatari dam down the Kiso river. In constructing this power station, vertical drilling of about 33m in depth was executed in soft sedimentary rock area with uniaxial compression strength of 100kgf/cm{sup 2} or so. This report describes the geological condition in the drilling area and the outline of design and execution of corresponding landslide preventions. The drilling area mainly consists of tuff-containing sandstone and conglomerate with several weak layers such as lignite layers, and its stratum slopes gently from the mountain side to the river side. When the landslide preventions were designed, it was especially considered to secure stability of the drilling surface of earth filling as well as to control shear deformation along the lignite layer. Based on the two-dimensional elasto-plastic FEM analysis, structural design of landslide prevention walls and reinforcing methods using ground anchors and lock-bolts were determined. Construction works have been proceeded with as the ground behavior has been measured and controlled by setting many instruments such as insertion-type clinometers on the landslide preventions and the back ground. 2 refs., 18 figs., 5 tabs.

    The design and construction of the Chichibu-Park Bridge in Japan were outlined which is the symmetric 2-span continuous PC cable stayed road bridge with one main tower (530 m in total length, 392 m in main bridge length, 19 m in width) built over the Arakawa River. The double-suspended four-box main girder with wind noses was adopted because of its excellent torsional rigidity of area and wind proof stability, and the rigid-frame main girder was rigidly connected to the middle main tower. The main tower with an H-type hollow section was adopted considering its workability, and was assembled with its divided 18 blocks. Each side of the main girder was suspended at 30 points spaced at 6.0 m, and the tower ends of the diagonal cables were fixed to the partition inside the main tower taking a landscape into account. The thick stranded wires composed of fine PC steel stranded wires and covered with polyethylene were adopted as diagonal cables, and structural beams were used for both ends of the diagonal cables. Damping wires were also adopted to damp the diagonal cables. 9 refs., 12 figs., 6 tabs.

    Structure and design of single suspension PC cable bridge, which is first kind of high way bridge in Japan and aiming to start for general use by March, 1993, are reported. As a construction outline, main construction quantity and general layout of the whole bridge together with the selective detail and characteristics of the diagonal member, tower, main girder and tower support member, are cited. Design conditions( load, materials, allowable stress and others ), basic plan of the design, and structure analysis( surface stress framed structure analysis, stereoscopic framework analysis and FEM analysis of local stress ) are explained. Design of structure member like main girder is based on diagonal member tension, wave shearing force, level of diagonal strain stress, bending stress when diagonal member anchors the deformed main tower caused by living load during earth quake, principal stress of main tower junction and local stress etc. Main tower support member design is based on the results of corbel shearing force at varied cross section and main stress, and diagonal member design is decided by allowable stress. Diagonal member anchorage traverse beam design depends on bending moment of traverse beam and shearing force. 3 refs., 15 figs., 1 tab.

    The Natorigawa Bridge is reconstructed. Out of the reconstruction work, a report is made mainly on the design of the superstructure work of the PC panel-stayed bridge and the details of the work. In selecting bridge type, PC simple through beam bridge, steel trussed bridge, PC cable-stayed bridge, and PC panel-stayed bridge are compared, and a 2-span continuous PC panel-stayed bridge is adopted. Its appearance resembles that of the cable-stayed bridge, but the structure resembles a girder bridge. The appropriate span length is the intermediate range between those of the girder bridge and the cable-stayed bridge. Its trafficability is excellent with little deformation by the running of trains because the main beam, diagonal panel, and the main tower are connected rigidly to provide high rigidity of the entire bridge. PRC structure is employed in consideration of the restriction to beam height and economical efficiency. Analyses by a FEM model using two dimensional plane elements and by a few plane frame models as well as comparison of sectional force are performed for this bridge, and a proper plane model is selected. Substructure work, superstructure work and measurement work are described. 3 refs., 16 figs., 6 tabs.

    The number of constructed prestressed concrete cable stayed bridges reached nearly 100 in Japan, and the technique has greatly developed. In this article, the current status of design techniques for prestressed concrete cable stayed bridges were introduced along with the examples of constructed bridges for the analysis method and the design method for each structure part while introducing the current examples of constructed bridges. Also, this kind of extra-dosed prestressed concrete bridge and prestressed concrete bridge with prestressed concrete stays were reported. Standards have been prepared including a chapter for the prestressed concrete cable stayed bridges in the Road Bridge Guideline document in February 1990. Load to be noticed as the characteristics peculiar to the prestressed concrete cable stayed bridges includes the shock due to live load, temperature change, and execution error of a tower. For example, 1/1000 of the total tower height is generally considered as the execution error of the tower. A diagonal member is manufactured at factories and in fields and has both advantages and disadvantages. The linear analysis of plane framework is general. Damping of and earthquakeproof designs against the wind and earthquake of the diagonal member were also provided. 11 refs., 17 figs., 2 tabs.

    This paper describes design, fabrication and erection of Queen Mall Bridge, which is a new landmark in Minato-Mirai Yokohama. This bridge is two-span continuous cable stayed pedestrian bridge with a roof, and has a length 72.2 m, a width 18 m and a weight about 1,050 t. This bridge connects between the Queen`s Square and the second floor of Pacifico Yokohama. Achieving harmonious impression of the newly designed bridge in this area, glass roof was employed and all-weld method was applied to the in-site jointing of main girders and main tower in addition to the essential structural design. Since all-weld method was applied to the in-site jointing, highly accurate fabrication was considered during the in-site jointing. Due to the heavy traffic of the road below the bridge, the erection time was shortened under the severe erection conditions at night by large block method. Especially, accuracy control was considered for the whole shape management. Pre-assemble of all members was conducted just near the erection site, only 500 m away from the site, to shorten the construction time. 1 ref., 5 figs.

    This paper describes the planning and design of the Ikeda-Lake Bridge of the Tokushima Express Way. This bridge is a PC (prestressed concrete) five-span continuous balanced arch bridge with a length 705 m. This bridge transverses prefectural road, Ikeda Dam Lake of Yoshino River, park, JR line, national highway, and town road, and both ends of the bridge are tunnels, resulting in the complicated bridging condition. Various bridging methods were examined from the viewpoint of structural characteristics, workability, profitability, maintenance/management, and aspect. A bridge with PC stiffening girders was adopted. The maximum interval between supports is 200 m. This bridge has the largest scale as a concrete arch bridge in Japan. Basements of bridge piers were constructed by pneumatic caisson method and large-diameter deep basement method. Since basements were located in the dam lake and they were quickly constructed in a short period in a non-flood season, steel caissons were separately fabricated in the dock, towed and placed for excavation. For the construction of upper section, overhang method was adopted using movable working vehicle. For the construction of arch section, the arch was overhung simultaneously in the both sides by composing the truss using stiffened girders, arch ribs, vertical members, and temporary cable stayed members, which was the first in Japan. In 1997, basement construction was completed, and construction of bridge piers and a part of the construction of upper section have been started. 2 refs., 12 figs.

    This report summarizes the fiscal 1999 research result on the aerodynamic design and seal design necessary for development of advanced hydrogen compressors for large-scale hydrogen liquefiers in the WE-NET plan. In the study on aerodynamic performance of impellers, 3-D viscous flow analysis of 2 types of new impeller forms (20 and 15 degrees) was carried out based on the study result on backward angle. The 2-D viscous flow analysis result on diffuser suitable for hydrogen compressors showed that improvement of the performance of a NACA65 type profile diffuser is possible. The study result on scale effect by using Casy's evaluation formula showed the efficiency difference of nearly 2.6% between impeller diameters of 1000mm and 300mm at 0.08 in exit width ratio. Study was made on hydrogen gas leak for spiral groove sealing selected as hydrogen gas sealing. The study on small capacity hydrogen liquefiers was conducted on the same process cycle as the 11t/d liquefier which has been commercially available. (NEDO)

    For the confirmation of safety for the geological disposal of radioactive wastes, it is very important to demonstrate the groundwater flow by in-situ investigation in the deep underground. We have developed a groundwater flow meter to measure simultaneously the velocity and direction of groundwater flow by means of detecting the electric potential difference between the groundwater to evaluate and the distilled water as a tracer in a single well. In this paper, we describe the outline of the groundwater flow meter system developed by CRIEPI and Taisei-Kiso-Sekkei Co. Ltd. and the evaluation methodology for observed data by using it in fractured rocks. Furthermore, applied results to in-situ tests at the Tounou mine of Japan Nuclear Fuel Cycle Development Institute (JNC) and the Aespoe Hard Rock Laboratory (HRL) of Swedish Nuclear Fuel and Waste Management Co. (SK) are described. Both sites are different type of fractured rock formations of granite. From these results, it was made clear that this flow meter system can be practically used to measure the groundwater flow direction and velocity as low as order of 1x10 -3 ∼10 -7 cm/sec. (author)

    In the R and D of the high temperature coal gasification technology by the entrained bed system which is the core technology of the coal utilization hydrogen production technology, the paper carried out the dismantling study of pilot plant and the summarization of the results. About the summarization of the results, as the results of the HYCOL operation study, there were insufficiencies in expansion of the coal kind used and acquisition of scale-up data, but it was verified that the conceptual design of the HYCOL method was fully applicable to the higher gasification efficiency, higher reliability, adaptability to many kinds of coal and compactness of facilities (low construction cost) which were the final subjects for the realization of commercial plant. This was highly evaluated. Especially, the greatest characteristic of the HYCOL method is the freedom in selection of temperature difference between the upper stage and lower stage, that is, temperatures can be controlled to temperatures they want in each of the upper stage and lower stage in the one-chamber gasifier according to coal properties and slagging control. The verification of this freedom was the base of the total results. Moreover, a reputation was being made that the gasification efficiency and process reliability are at the world's highest level.

    Chiburiko Bridge lies across Chiburiko which is a lake for agricultural water, and is used by people, carts and cars for administration. It is a stressed-ribbon bridge with the road surface made with concrete covered bands of cables stretched between abutments, and is the first highway bridge in Japan. A report is made on the plan and construction of the bridge. Integration of the precast slab with the cast-in-place concrete as well as mutual integration of the precast slabs are validated by the use of a reproduced model of a part of the bridge. Floor slabs are suspended by cables, and can be constructed with no form nor support by integrating cast-in-place concrete with the precast slabs on mutually joined precast slabs. It has been said that the stressed-ribbon bridge has a structure suitable for long span bridges because it has a simple structure. Studies, however, seems to be necessary on the impact caused by running of vehicles and on the wind resisting stability. 3 refs., 17 figs., 2 tabs.

    This project aims at development, demonstration and utilization of waste recycling technologies. This report summarizes the fiscal 1998 results. The test/demonstration plant for separation and removal of foreign materials was constructed for effective use of waste building wood, and its optimum operation condition was studied. Although some foreign materials exists, 90% of waste building wood chips were separated and recovered through some improvements for the plant. An advanced separation technology is expected. As for fibering technology, fibers with target compression strength were obtained from cedar chips through a disintegration experiment using a newly developed refiner plate. Although the compression strength of fibers obtained from waste building wood chips was slightly poor, it is attained by increasing the target specific gravity of light- weight wooden materials by nearly 10% from 0.1. As for fiber orientation technology, as the tension of a forming belt was adjusted to achieve sufficient width compression, nearly 90% of the target compression strength was attained. A width compression method remains to be solved. (NEDO)

    The needs for low power LSIs have rapidly increased recently. For the low power LSI development, not only new circuit technologies but also new design automation tools supporting the new technologies are indispensable. The purpose of this project is to develop a new design automation software, which is able to design new digital LSIs with much lower power than that of conventional CMOS LSIs. A new design automation software for very low power LSIs has been developed targeting the pass-transistor logic SPL, a dedicated low power circuit technology. The software includes a logic synthesis function for pass-transistor-based macrocells and a macrocell placement function. Several new algorithms have been developed for the software, e.g. BDD construction. Some of them are designed and implemented for parallel processing in order to reduce the processing time. The logic synthesis function was tested on a set of benchmarks and finally applied to a low power CPU design. The designed 8-bit CPU was fully compatible with Zilog Z-80. The power dissipation of the CPU was compared with that of commercial CMOS Z-80. At most 82% of power of CMOS was reduced by the new CPU. On the other hand, parallel processing speed up was measured on the macrocell placement function. 34 folds speed up was realized. (NEDO)

    A rough design was performed on a floating airport. On this floating structure, environmental external force was estimated, mooring design was carried out, and discussions was given on the position retaining performance important for airport functions and behavior of the floating structure. The discussion was given on cases that the airport is surrounded and not surrounded by floating breakwaters. A floating structure which becomes super-large in size requires considerations on force due to sea level gradient as a result of a tide. Deriving flow condition changes and force acting on the floating structure simultaneously by using numerical calculations makes it possible to estimate current force given with considerations on influence of the flow conditions created by installing the floating airport. Estimation was carried out by using a zone dividing method on wave drifting force acting upon the floating airport. As a result, it was found that installing floating and permeating type breakwaters can reduce the wave drifting force acting on the floating airport. The wave drifting force working on the floating airport can be reduced by installing the floating and permeating type breakwaters to lower levels than when no such breakwaters are installed. The airport may be moored with less number of fenders when the fenders of the same type are used. 18 refs., 10 figs., 5 tabs.

    This paper reports the design and construction of landslide preventive construction at the site of the Yamasubara hydroelectric power plant (with a maximum output of 40,700 kW) and the result of slope stability verification after completion of the construction. The moderate slope on top of the primary slide has sands presumed to be colluvial deposit distributed with a depth of 10 m or more, where occurrence of a secondary slip was feared as triggered by the primary slide. The power plant protective constructions consisted of concrete walls to protect the entire power plant including buildings, and falling stone protective fences installed around the surge tanks. The temporary measures were so set that groundwater levels are lowered to a level that can assure the slide safety factor of 1.0 or more by means of drain boring using the down-the-hole hammer type. The permanent protective construction used rock anchors that are superior in constructability and economy. The stability of sliding slope faces was verified to confirm effects of the protective constructions. The verification included observations of groundwater level behavior, water well-up from drain holes, and movements in the slopes. The result showed that the protective constructions have give sufficient effects. Continued slope stability control is important. 16 figs., 7 tabs.

    This paper describes an influence of additional elements on the high temperature deformation behavior of Nb-base solid solution alloys. Highly concentrated solid solution single crystals of Nb-Ta and Nb-Mo alloys were prepared. Compression test and strain rate sudden change test were conducted in the vacuum at temperatures ranging from 77 to 1773 K, to determine the strain rate sensitivity index. Yield stress of the Nb-Ta alloy was similar to that of Nb alloy at temperatures over 0.3{times}T{sub M}, where T{sub M} is fusing point of Nb. While, the yield stress increased with increasing the impurity oxygen concentration at temperatures below 0.3{times}T{sub M}. The yield stress became much higher than that of Nb alloy. The strain rate sensitivity index showed positive values in the whole temperature range. On the other hand, the yield stress of Nb-Mo alloy was higher than that of Nb alloy in the whole temperature range, and increased with increasing the Mo concentration. The strain rate sensitivity index showed negative values at the temperature range from 0.3{times}T{sub M} to 0.4{times}T{sub M}. It was found that serration occurred often for Nb-40Mo alloys. 1 ref., 4 figs., 1 tab.

    A report on design and execution of cable-stayed composite girder bridge with precast RC-slabs constructed first in Japan though in small scale was described. This bridge adopted steel slabs relatively low in slab height for main slab and with two boxes slab section, and was designed at an aim of being more economic and shorter in its working term in comparison with steel girder slab type, on a base of the design in a region allowable with the existing design standards. This bridge is mainly in accordance with the regulation on continuous bridge in the prescription of road bridge, and is designed for normal RC-girder selecting between girder supports to direction normal to bridge axis as usual without using specially strong concrete to the girder. And, in order to fill with the regulation on allowable tensile stress on considering effects of creep and drying shrinkage, a method adding prestress to the slabs was adopted. Furthermore, a loop-like overlap joint for cable joint for the precast girders, expansion concrete for joint portion to compose the girder with the steel slab and so forth were adopted. 12 refs., 22 figs., 5 tabs.

    Aomori Bay Bridge is a 1,219m long elevated bridge, a part of No.2 Bay Highway of 1,993m in total length crossing over Aomori railway station which was planned in ordecr to integrate the port facilities of Aomori Harbor and expedite cargo traffic smoothly. Of this Bay Bridge, its main bridge portion crossing over Aomori railway station and the sea area was planned as a continuous prestressed concrete cable-stayed bridge of 498m in total length and consisting of three portions including the central portion in which the main span between the central bridge piers was 240m. It is scheduled to open in the summer of 1992. With regard to the design of this bridge, special care for the view of the bridge has been taken covering from the structure style to the accessories. For this bridge, a large scale underground continuous wall solid base with a box-shaped section consisting of 6 chambers was adopted for the base of a main tower. It has the cantilever suspension structure of the wide girder with the inverted Y-shaped pylons. For its stav cable, was adopted a large capacity stay cable with standard tensile strength of 1,942 fabricated on the site and for its covering tube, a FRP tube was adopted. In this article, the construction of the main girder and stay cables, and the construction control during their installation by projection are reported. 7 refs., 14 figs., 9 tabs.

    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.

    Technology has now progressed to the point that intelligent systems are replacing humans in the decision making processes as well as aiding in the solution of very complex problems. In many cases intelligent systems are already outperforming human activities. 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

    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.

    A policy of improving a very large floating body was planned based on its dynamic characteristics, and a proposal was made thereon. Furthermore, discussions were given on stability that considers effect of elastic deformation required when a structure is mounted on a floating body. With respect to a structural design of a very large floating body in which elastic response is governing, and upon modeling the very large floating body into an aeolotropic plate on an elastic supporting floor, it was shown that the existing range of natural vibration speed in the elastic response is in higher range than the natural vibration speed of heave. It was also indicated that the peak height of response to waves in resonance is inversely proportional to wave frequency, and furthermore, degree of flowing in of vibration energy during the resonance is determined by an inner product of spatial vibration patterns of wave force and the excited mode shape. A proposal was made on a floating body improved of excessive response in the floating body edges by changing the characteristics of the floating body edges. In addition, discussions were given on stability that considers elastic deformation of a floating body that becomes necessary when a structure, such as a building, is built on a very large floating body. 9 refs., 9 figs., 3 tabs.

    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)

    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...

    2008-11-01

    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.

    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)

    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.)

  1. System Dynamics

    Science.gov (United States)

    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. Such confusion starts already with the term 'energy crisis'. Is there an energy crisis or not? Much future work is required to tackle the problems of energy systems.

    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)

    1982-09-23

    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.

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...

    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%

    A method for determining part re-use and recycling strategy in product design is considered for optimal design of total product life cycle based on the concept of Right Quality Products. For this purpose, it is important to be able to estimate part deterioration status under various product usage conditions. For supporting product designers' decision making about the product life cycle in preliminary design phase, the deterioration estimation is not required to be very exact, but to generate every possible deterioration modes qualitatively. Then, based on these deterioration modes, functional behaviour of target products is simulated, and possible product failure modes can be generated. By utilizing the FMEA (Failure Mode and Effect Analysis) method, the effects of failure modes are evaluated, and the results are fed back to product designers for confirming their design in terms of total product life cycle optimization. A basic methodology is considered, and case study has been done for a mechanical assembly of a one-time use camera. The assembly consists of injection molded parts. Various CAE methods have been used for predicting possible part failures due to initial residual stress, warp, fatigue, creep, and wear. Then kinematic and dynamic analysis of mechanical assembly has been done for detecting the effect of part deterioration on mechanism movements. Several critical failure modes have been detected, and the effects of those failures have been checked by the FMEA method. (NEDO)

    R and D was conducted for the purpose of developing the alternative natural gas manufacturing process that, using coal as the raw material, is highly efficient as well as environmentally superior, with the fiscal 1996 results reported. A test research was carried out on the coal hydrogasification process which was selected as the optimum process based on the studies in the previous years. On the basis of the results of the studies, a free fall pyrolyzer was employed as the test equipment for the use of behavior research of hetero-elements in the test. The basic specifications were set based on a hydrogen/coal ratio of 0.2, a temperature of 950 degrees C and a pressure of 7 MPa, which are the reaction conditions of the ARCH reactor, with the basic design drafted accordingly. In a preliminary examination on the mechanisms of the coal hydrogasification reaction, analysis was made on the representative 20 different kinds of coals, on the six kinds of which studies were made on the gasification behavior using a constant heating rate pyrolyzer. As a result, from the temperature dependency of a methane forming speed, it was assumed that three components of coal had bearing upon the gasification behavior. (NEDO)

    R and D was conducted for the purpose of developing the alternative natural gas manufacturing process that, using coal as the raw material, is highly efficient as well as environmentally superior, with the fiscal 1998 results reported. A hydrogasification test was conducted on Taiheiyo coal at a temperature of 1,173k and a pressure of 7 MPa, which showed that all gaseous products other than methane stopped their evolution roughly in the heat-up process, while methane continued to evolve to show the highest yield. In the reactivity comparison of various types of coal, coals with carbon content of 80% or below were high in reactivity and considered suitable for hydrogasification feedstock. It was also suggested that the hydrogasification reactivity of low rank coals including sub-bituminous coals or below might be greatly affected by the presence/absence of the catalytic effects of ion-exchanged metals. Behavior experiments of sulfur and nitrogen in coal in the hydrogenation reaction were carried out using a continuous free-fall type reactor, which elucidated the effects of hydrogen pressure and gas residence time among various operational elements.

A basic methodology is considered, and case study has been done for a mechanical assembly of a one-time use camera. The assembly consists of injection molded parts. Various CAE methods have been used for predicting possible part failures due to initial residual stress, warp, fatigue, creep, and wear. Then kinematic and dynamic analysis of mechanical assembly has been done for detecting the effect of part deterioration on mechanism movements. Several critical failure modes have been detected, and the effects of those failures have been checked by the FMEA method. (NEDO)

    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.

However, the efficacy is not well reported. Therefore, the objective of the study was to conduct a systematic review and meta-analysis of the available evidence on prevention of uncomplicated wound infections by prophylactic topical antibiotics. Materials and methods: The search included Pubmed, Google Scholar, SCOPUS, Embase, Cochrane, ClinicalTrials.gov, International Clinical Trials Registry Platform, National Technical Information Service, and the National Guidelines Clearinghouse. Results: We identified eight randomized controlled trials and four quasi-randomized trials that met the criteria for the systematic review. Of these trials, 11 studies were pooled for meta-analysis to compare the effects of topical antibiotics versus placebo and 4 studies were pooled for comparison of effects of topical antibiotics versus topical antiseptics on uncomplicated wounds. Fewer wound infections occurred in the topical antibiotic arms compared to placebo (pooled risk ratio: 0.57 [95% CI: 0.37 to 0.86]; p=0.01 and pooled risk

    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...

    Utilizing cooling properties and current voltage characteristics of a small cooling panel using thermoelectric elements which had been fabricated previously on a trial basis, design and prototype production were executed on a large radiant cooling and heating panel driven by photovoltaic cell modules. The panel design set the cooling area to about 0.5 m {sup 2} and the number of elements to 70 pieces, and optimum number of elements in series and parallel connection was derived. As a result of the analysis, it was made clear that the optimum number of thermoelectric module arrays in series and parallel connection varies depending on insolation intensity. It was found preferable that the number of parallel connection array be set to one to two in a region or time period in which low insolation intensity is distributed in greater amount. In the case where high insolation intensity is distributed in a greater amount, setting it to two to three is preferable. By using the structured design method and the HASP Tokyo data, thermoelectric element modules were interconnected with 35 modules in series and two in parallel on a cooling panel installed on the roof of the Science University of Tokyo. A simulation result revealed that the average temperature difference on the cooled surface in summer is 4.37 degC, and the solar cell utilization rate is 0.67. It is necessary in the future to improve heat dissipation efficiency and area ratio. 1 ref., 12 figs., 5 tabs.

    2008-01-01

    Operating systems provide the fundamental mechanisms for securing computer processing. Since the 1960s, operating systems designers have explored how to build "secure" operating systems - operating systems whose mechanisms protect the system against a motivated adversary. Recently, the importance of ensuring such security has become a mainstream issue for all operating systems. In this book, we examine past research that outlines the requirements for a secure operating system and research that implements example systems that aim for such requirements. For system designs that aimed to

    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.

The systemic administration of acetylsalicylic acid decreases endothelial dysfunction, potentially reducing thrombus, enhancing vasodilatation, and inhibiting the progression of atherosclerosis; but, this is weakened by upper gastrointestinal bleeding. This study proposes a hybrid stent with biodegradable nanofibers, for the local, sustained delivery of acetylsalicylic acid to injured artery walls. Biodegradable nanofibers are prepared by first dissolving poly(D,L-lactide-co-glycolide and acetylsalicylic acid in 1,1,1,3,3,3-hexafluoro-2-propanol. The solution is then electrospun into nanofibrous tubes, which are then mounted onto commercially available bare-metal stents. In vitro release rates of pharmaceuticals from nanofibers are characterized using an elution method, and a high-performance liquid chromatography assay. The experimental results suggest that biodegradable nanofibers

    System 7 is a single-user graphical user interface-based operating system for Macintosh computers and was part of the classic Mac OS line of operating systems. It was introduced on May 13, 1991, by Apple Computer. It succeeded System 6, and was the main Macintosh operating system until it was succeeded by Mac OS 8 in 1997. Features added with the System 7 release included virtual memory, personal file sharing, QuickTime, QuickDraw 3D, and an improved user interface. This is the first real major evolution of the Macintosh system, bringing a significant improvement in the user interface, improved stability and many new features such as the ability to use multiple applications at the same time. "System 7" is the last operating system name of the Macintosh that contains the word "system". Macintosh operating systems were later called "Mac OS" (for Macintosh Operating System).

    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.

    Hazardous wastes contaminated with radionuclides, chemicals, and explosives exist across the Department of Energy complex and need to be remediated due to environmental concerns. Currently, an opportunity is being developed to dramatically reduce remediation costs and to assist in the acceleration of schedules associated with these wastes by deploying a Hot Spot Removal System. Removing the hot spot from the waste site will remove risk driver(s) and enable another, more cost effective process/option/remedial alternative (i.e., capping) to be applied to the remainder of the site. The Hot Spot Removal System consists of a suite of technologies that will be utilized to locate and remove source terms. Components of the system can also be used in a variety of other cleanup activities. This Hot Spot Removal System Description document presents technologies that were considered for possible inclusion in the Hot Spot Removal System, technologies made available to the Hot Spot Removal System, industrial interest in the Hot Spot Removal System`s subsystems, the schedule required for the Hot Spot Removal System, the evaluation of the relevant technologies, and the recommendations for equipment and technologies as stated in the Plan section.

    The Site Systems Engineering Management Plan (SEMP) is the Westinghouse Hanford Company (WHC) implementation document for the Hanford Site Systems Engineering Policy, (RLPD 430.1) and Systems Engineering Criteria Document and Implementing Directive, (RLID 430.1). These documents define the US Department of Energy (DOE), Richland Operations Office (RL) processes and products to be used at Hanford to implement the systems engineering process at the site level. This SEMP describes the products being provided by the site systems engineering activity in fiscal year (FY) 1996 and the associated schedule. It also includes the procedural approach being taken by the site level systems engineering activity in the development of these products and the intended uses for the products in the integrated planning process in response to the DOE policy and implementing directives. The scope of the systems engineering process is to define a set of activities and products to be used at the site level during FY 1996 or until the successful Project Hanford Management Contractor (PHMC) is onsite as a result of contract award from Request For Proposal DE-RP06-96RL13200. Following installation of the new contractor, a long-term set of systems engineering procedures and products will be defined for management of the Hanford Project. The extent to which each project applies the systems engineering process and the specific tools used are determined by the project`s management.

    System integration (SI) is defined as combining hardwares and softwares as the infrastructures with know-hows for their use comprehensively to respond to high-level needs of users. This paper reports the features of an SI being developed by a company (E Company), its concept on the systematized development methodology, and the conceptual models. With the primary policy placed on creative integration standing on customers positions, the SI concept comprises three parts of models for evaluations as seen from the customers, evaluations as seen from the E Company, and the development object systems to link both parts. The third part is further consisted of several lower hierarchies including a customer controlled system hierarchy (this enables customers to control the system through visualization, for example, and includes three logic models (multiple solution selection, optimal solution under restricted conditions, and numerical solution)). 2 refs., 9 figs.

    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.

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

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.)

    Full Text Available Usually, a Big Data system has a monitoring system for performance evaluation and error prevention. There are some disadvantages in the way that these tools display the information and its targeted approach to physical components. The main goal is to study visual and interactive mechanisms that allow the representation of monitoring data in grid computing environments, providing the end-user information, which can contribute objectively to the system analysis. This paper is an extension of the paper presented at (Pinho and Carvalho 2016 and has the purpose to present the state of the art, carries out the proposed solution and present the achieved goals.

    This paper discusses the architectural design features to be employed by Westinghouse in the application of distributed digital processing techniques to the protection system. While the title of the paper makes specific reference to microprocessors, this is only one (and the newest) of the building blocks which constitutes a distributed digital processing system. The actual system structure (as realized through utilization of the various building blocks) is established through considerations of reliability, licensability, and cost. It is the intent of the paper to address these considerations licenstions as they relate to the architectural design features. (orig.) [de

    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.

    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.

    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.

    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.
