    The Aerospace Corporation is sponsoring research into the development and use of Nanotechnology Instrumentation in support of Space Launch applications. The intent is to use nanotechnology-based commercial-off-the-shelf components (COTS) micro-electromechanical (MEMS) and in-house developed sensors as basis for a wired or wireless sensors instrumentation and detection system. As part of this effort, the Aerospace Materials and Mechanics Technology Center (MMTC) is supporting the development and testing of a wireless Multi-parameter Sensor (MPS) instrumentation system and a chemical microsensor for the detection of hydrogen chloride (HCl) gas in solid rocket motor exhaust plumes. This paper documents and describes the progress made in the development and testing of these MEMS-based instrumentation.

  2. The APS machine protection system (MPS)

    International Nuclear Information System (INIS)

    The machine protection system (MPS) that protects the APS storage ring vacuum chamber from x-ray beams, is active. There are over 650 sensors monitored and networked through the MPS system. About the same number of other process variables are monitored by the much slower EPICS control system, which also has an input to the rf abort chain. The MPS network is still growing with the beam position limits detection system coming on-line. The network configuration, along with a limited description of individual subsystems, is presented

  5. 3D simulation of eutectic interaction of Pb–Sn system using Moving Particle Semi-implicit (MPS) method

    International Nuclear Information System (INIS)

    Highlights: • Development of MPS eutectic model for solid–solid interaction. • Analysis of experiments dealing with eutectic behavior of Pb–Sn by MPS simulation. • The analysis has revealed the mechanism of eutectic melting due to eutectic reaction. - Abstract: The eutectic reaction phenomenon was analyzed based on the Moving Particle Semi-implicit (MPS) method. The improved MPS code was applied to three-dimensional Pb–Sn system experiments conducted at Central Research Institute of Electric Power Industry (CRIEPI). The experiments dealt with solid–solid contact materials at 225 and 205 °C. The mass diffusion process was modeled based on Fick’s second law. The criterion of eutectic reaction was modeled based on binary phase diagram. The calculated penetration rates, i.e. height reduction rates, were compared with the experimental measurements. The results obtained by the MPS simulations exhibit good agreement with the experiments carried out at 205 and 225 °C. MPS simulation predicted that Sn particle will liquefy earlier than Pb particle

    The potential host immune response to a nonself protein poses a fundamental challenge for gene therapies targeting recessive diseases. We demonstrate in both dogs and nonhuman primates that liver-directed gene transfer using an adeno-associated virus (AAV) vector in neonates induces a persistent state of immunological tolerance to the transgene product, substantially improving the efficacy of subsequent vector administration targeting the central nervous system (CNS). We applied this approach to a canine model of mucopolysaccharidosis type I (MPS I), a progressive neuropathic lysosomal storage disease caused by deficient activity of the enzyme ?-l-iduronidase (IDUA). MPS I dogs treated systemically in the first week of life with a vector expressing canine IDUA did not develop antibodies against the enzyme and exhibited robust expression in the CNS upon intrathecal AAV delivery at 1 month of age, resulting in complete correction of brain storage lesions. Newborn rhesus monkeys treated systemically with AAV vector expressing human IDUA developed tolerance to the transgene, resulting in high cerebrospinal fluid (CSF) IDUA expression and no antibody induction after subsequent CNS gene therapy. These findings suggest that inducing tolerance to the transgene product during a critical period in immunological development can improve the efficacy and safety of gene therapy. PMID:26022732

    1994-01-01

    The DET/MPS programs model and simulate the Direct Energy Transfer and Multimission Spacecraft Modular Power System in order to aid both in design and in analysis of orbital energy balance. Typically, the DET power system has the solar array directly to the spacecraft bus, and the central building block of MPS is the Standard Power Regulator Unit. DET/MPS allows a minute-by-minute simulation of the power system's performance as it responds to various orbital parameters, focusing its output on solar array output and battery characteristics. While this package is limited in terms of orbital mechanics, it is sufficient to calculate eclipse and solar array data for circular or non-circular orbits. DET/MPS can be adjusted to run one or sequential orbits up to about one week, simulated time. These programs have been used on a variety of Goddard Space Flight Center spacecraft projects. DET/MPS is written in FORTRAN 77 with some VAX-type extensions. Any FORTRAN 77 compiler that includes VAX extensions should be able to compile and run the program with little or no modifications. The compiler must at least support free-form (or tab-delineated) source format and 'do do-while end-do' control structures. DET/MPS is available for three platforms: GSC-13374, for DEC VAX series computers running VMS, is available in DEC VAX Backup format on a 9-track 1600 BPI tape (standard distribution) or TK50 tape cartridge; GSC-13443, for UNIX-based computers, is available on a .25 inch streaming magnetic tape cartridge in UNIX tar format; and GSC-13444, for Macintosh computers running AU/X with either the NKR FORTRAN or AbSoft MacFORTRAN II compilers, is available on a 3.5 inch 800K Macintosh format diskette. Source code and test data are supplied. The UNIX version of DET requires 90K of main memory for execution. DET/MPS was developed in 1990.

    Maps, and more importantly Atlases, are assisting the user community in managing a large land area with complex issues, the most complex of which is the management of nuclear waste. The techniques and experiences discussed herein were gained while developing several atlases for use at the US Department of Energy's Hanford Site. The user community requires the ability to locate not only waste sites, but other features as well. Finding a specific waste site on a map and in the field is a difficult task at a site the size of Hanford. To find a specific waste site, the user begins by locating the item or object in an index, then locating the feature on the corresponding map within an atlas. Locating features requires a method for indexing them. The location index and how to place it on a map or atlas is the central theme presented in this article. The user requirements for atlases forced the design team to develop new and innovative solutions for requirements that Product Line Tool Set (PLTS) Map Production System (MPS)-Atlas was not designed to handle. The layout of the most complex atlases includes custom reference grids, multiple data frames, multiple map series, and up to 250 maps. All of these functional requirements are at the extreme edge of the capabilities of PLTS MPS-Atlas. This document outlines the setup of an atlas using PLTS MPS-Atlas to meet these requirements.

    A series of tests was conducted on two 12 ampere hour nickel cadmium batteries under a simulated cycle regime using the multiple voltage versus temperature levels designed into the modular power system (MPS). These tests included: battery recharge as a function of voltage control level; temperature imbalance between two parallel batteries; a shorted or partially shorted cell in one of the two parallel batteries; impedance imbalance of one of the parallel battery circuits; and disabling and enabling one of the batteries from the bus at various charge and discharge states. The results demonstrate that the eight commandable voltage versus temperature levels designed into the MPS provide a very flexible system that not only can accommodate a wide range of normal power system operation, but also provides a high degree of flexibility in responding to abnormal operating conditions.

    The use of Duratek's Mobile Process System (MPS) employing sluiceable pressure vessels and improved operational techniques generates operational efficiencies including volume reduction (VR), reduced personnel labor and exposure and higher flowrates for cleanup of liquid radwaste streams in an operating nuclear power plant (Salem Generating Station). Significant additional VR is achievable based on laboratory and on-site experience utilizing Durasil 70. Under high conductivity, actual waste stream conditions, this proprietary media has demonstrated through-puts of a magnitude 15 times higher than organic cation resin. A long-term problem, cobalt species removal, is mitigated by this media

    During the 2010 run, the MPS have been additionally stressed by the commissioning of operational procedures and systems tests. As requested by the MPS external review committee, human factors have to be further minimized and discipline reinforced when increasing the stored beam energies towards and beyond the 2010 target of 30 MJ. This talk will present a synthesis of the Evian discussion on MPS and human factors, with an emphasis on the tools and procedures to be put in place for the 2011 run in order to ensure the machine safety during standard beam operation and after periods of machine developments or technical stops.

    The Naval Postgraduate School Advanced Design Project sponsored by the Universities Space Research Association Advanced Design Program is a multipurpose satellite bus (MPS). The design was initiated from a Statement of Work (SOW) developed by the Defense Advanced Research Projects Agency (DARPA). The SOW called for a 'proposal to design a small, low-cost, lightweight, general purpose spacecraft bus capable of accommodating any of a variety of mission payloads. Typical payloads envisioned include those associated with meteorological, communication, surveillance and tracking, target location, and navigation mission areas.' The design project investigates two dissimilar missions, a meteorological payload and a communications payload, mated with a single spacecraft bus with minimal modifications. The MPS is designed for launch aboard the Pegasus Air Launched Vehicle (ALV) or the Taurus Standard Small Launch Vehicle (SSLV).

  17. Replacement of heavy components of the Main Primary System (MPS). Recent innovations made by Framatome ANP

    International Nuclear Information System (INIS)

    The replacement of heavy components is the result of widespread stress corrosion of Inconel 600 (and alloys 82/182) in the primary system. Following the corrosion of steam generator tubes, which led to the first steam generator replacement (SGR) operations, work has begun on reactor vessel head replacements (RVHR) and pressurizer replacements, pending treatment of the dissimilar butt welds (DBW). The replacement of sections of the Main Primary System is one way of optimizing plant lifetime besides preventing stress corrosion in primary components and combating phenomena as thermal fatigue or certain metallurgical weaknesses. The increase in the number of major operations carried out in the reactor building on PWR and BWR reactor geometries has called for major technical innovations. AREVA, has over the past twenty years carried out more than forty SGRs throughout the world, including the supply of 115 steam generators of all types. This equates to over 60% of all SGR operations performed in Europe and the USA. Today, most SGR operations are performed in the USA, though some still continue in Europe and Asia. Operations have been planned until 2015. The first RVHR operations were carried out in France in 1993, and have been widespread in Europe since 1996 (Spain and Belgium), and in the USA since 2002 (Davis Besse). Since 1993 AREVA, through its subsidiaries Framatome ANP, Jeumont SA and SGT, has performed 72 RVHRs, i.e. most of those carried out in Europe and the USA. Today, RVHR operations take place throughout the world and have been planned until 2014. The first pressurizer replacement took place in the fall of 2005 in Saint Lucie, USA. Others are to follow (Fort Calhoun, Millestone). A significant number of partial or complete pressurizer replacements are now being scheduled. Special focus must be given to this new operation, as a decision is required between the following types of replacements, taking into account the number of pressurizer heaters and the condition of the various penetrations (lateral or from above, for instrumentation, unloading, spraying, etc.): - Complete replacement of the component (including dissimilar metal welds, thermal sleeves and even a section of the surge line if necessary); - Bottom replacement; - Replacement of faulty penetrations only. Along with the regular replacement of molded Main Primary System elbows (SGR operations), the following actions have also been carried out: - Replacement of a half crossover leg (SGR-GR4, 2000); - Replacement of a cold leg section (RCLS) with a chemical and volume control system (CVCS) nozzle (SGR-FH1, 2002). In the future we predict work will be carried out on the pressurizer surge line (potentially carried out as part of a pressurizer changeover or as a stand-alone operation). This presentation will focus on the major innovations developed by Framatome ANP, aided by its international customers in order to carry out these primary component replacement operations as well and as quickly as possible. These innovations concern the following domains: - Hoisting and handling; - Metrology and topo-metry; - Machining and welding; - Automated operations in piping; - Operation management. In conclusion one stresses that to increase the lifetime of their nuclear plants, optimize outages and sometimes increase thermal and electrical power it is necessary to optimize the replacement of heavy primary components. To meet the operator needs, suppliers must in turn enhance their capacity and skills in terms of: - Providing near-turnkey services (supplies and work); - Orchestrating these operations (i.e. by performing the duties of an engineering department); - Providing services in a range of fields, from concrete to instrumentation and control, and even performance testing; - Being technically innovative in all of these areas. Since the 1990's, with the assistance of its worldwide customer base, Framatome ANP has been carrying out this approach thanks to its experience as a vendor and manufacturer (OEM), bolstered by the capacities of its Engineering Departments and R and D Centers

  19. Development of the machine protection system for LCLS-I

    International Nuclear Information System (INIS)

    Machine Protection System (MPS) requirements for the currently operating Linac Coherent Light Source (LCLSI) demand that fault detection and mitigation occur within one machine pulse (1/120 of a second at full beam rate). The MPS must handle inputs from a variety of sources including loss monitors as well as standard state-type inputs. These sensors exist at various places across the full 2.5 Km length of the accelerator and beam lines. A new MPS has been developed based on a distributed star network where custom-designed local hardware nodes handle sensor inputs and mitigation outputs for localized regions of the LCLS accelerator complex. These Link- Nodes report status information and receive action commands from a centralized processor running the MPS algorithm over a private network. The individual Link-Node is a 3u chassis with configurable hardware components that can be setup with digital and analog inputs and outputs, depending upon the sensor and actuator requirements. Features include a custom MPS digital input/output subsystem, a private Ethernet interface, an embedded processor, a custom MPS engine implemented in an FPGA and an Industry Pack (IP) bus interface, allowing COTS and custom analog/digital I/O modules to be utilized for MPS functions. These features, while capable of handling standard MPS state-type inputs and outputs, allow other systems like beam loss monitors to be completely integrated within it. To date, four different types of Link-Nodes are in use in LCLS-I. This paper describes the design, construction and implementation of the LCLS MPS with a focus on the Link-Node, which has proven to be a very useful and flexible component for the MPS. (authors)

  2. MPS beam control software architecture

    International Nuclear Information System (INIS)

    The new Machine Protection System (MPS) now being tested at SLAC has a beam control subsystem resident in processors located close to the beam monitoring devices within the machine. There are two types of beam control micros: Algorithm Processors (AP's) which collect and evaluate data from monitoring devices, and a Supervisor (SUPE) which collects and evaluates data from all the AP's. The SUPE also receives the global machine beamcode indicating beam presence, and passes it on to the AP's. The SUPE receives the beamcode pattern from the Master Pattern Generator (MPG) via a shared-memory communication link. MIL-1553 serial communication is used between the SUPE and the AP's, and between the AP's and the monitoring devices. Multitasking software is used to allow high priority handling of data evaluation and low priority handling of host/user interfacing and event reporting. Pipelining of data between acquisition and evaluation and reporting is used to accomodate the processing capacity, while still supporting full processing at the 360Hz broadcast rate of the beamcode pattern

  6. Acid mucopolysaccharides (MPS) in fibroblast cultures. 4

    International Nuclear Information System (INIS)

    Cultures of embryonic rat fibroblasts were incubated with 35S-sulfate at pH 6.6 and 7.4 (Eagle medium, Hepes buffer) for 48 hours. The MPS were isolated and fractionated. Determination of hexuronic acid was done according to Bitter and Muir, measuring of sulfate incorporation by liquid scintillation counting. It could be demonstrated in which way the MPS pattern was modified in fibroblast cultures by changes in the concentrations of lactate and protons. Individually acting anabolic and catabolic processes that were influenced by cell density, pH and lactate were decisive factors for the MPS pools concerned. (author)

  7. MPS Vax monitor and control software architecture

    International Nuclear Information System (INIS)

    The new Machine Protection System (MPS) now being tested at the SLAC Linear Collider (SLC) includes monitoring and controlling facilities integrated into the existing VAX control system. The actual machine protection is performed by VME micros which control the beam repetition rate on a pulse-by-pulse basis based on measurements from fault detectors. The VAX is used to control and configure the VME micros, configure custom CAMAC modules providing the fault detector inputs, monitor and report faults and system errors, update the SLC database, and interface with the user. The design goals of the VAX software include a database-driven system to allow configuration changes without code changes, use of a standard TCP/IP-based message service for communication, use of existing SLCNET micros for CAMAC configuration, security and verification features to prevent unauthorized access, error and alarm logging and display updates as quickly as possible, and use of touch panels and X-windows displays for the user interface

    Many real-world systems are multistate systems composed of multistate components in which the reliability can be computed in terms of the lower bound points of level d, by formulating in terms of either the d-minimal paths (d-MPs) or d-minimal cutsets (d-MCs). Such systems (electric power, transportation, etc.) may be regarded as flow networks whose arcs have independent, discrete, limited and multivalued random capacities. A simple method is proposed to search for all d-MPs for network reliability in a system subject to both arc and node failures. The proposed method does not require re-enumeration for all of the d-MPs or MPs for the additional the node failure consideration. Because only the sum of the flow through into (or from) each unreliable node of the d-MPs which found in the network with perfect nodes is calculated, the proposed algorithm is easier to understand and implement. With considering unreliable nodes, this method is also more realistic and valuable for performing the reliability analysis in an existing network. The computational complexity of the proposed algorithm is analyzed and compared with the existing methods. One example is illustrated to show how all d-MPs are generated in a network with arc and node failures solved by the proposed algorithm

  10. Seed-mediated synthesis and structural analysis of hierarchical silver microparticles (HiAgMPs) with highly nanotextured surfaces

    International Nuclear Information System (INIS)

    Highlights: • Hierarchical silver microparticles (HiAgMPs) were synthesized by the seed-mediated method using silver nanoplates as seeds. • The growth of HiAgMPs under various synthetic conditions was analyzed by time-dependent scanning electron microscopy. • The internal structure of HiAgMPs was thoroughly investigated by direct electron microscopic observation and N2 isotherm. - Abstract: We developed a novel method to synthesize hierarchical silver microparticles (HiAgMPs) with highly nanotextured surfaces based on the seed-mediated synthesis by using silver nanoplates as seeds. The synthetic conditions for the resultant HiAgMPs were intensively investigated with various types and concentrations of nanoparticle seeds at different Ag+ concentrations. The growth mechanism of the HiAgMPs was studied by monitoring the morphological evolution at different growth phases. Importantly, we, for the first time, analyzed the internal structure of the HiAgMPs, which are composed of a packed core surrounded by a grooved shell. The catalytic properties of the HiAgMPs were investigated and determined to be highly active for the reduction of 4-nitrophenol

  11. Development of d.c. power supply for gyrotron with energy recovery system

    International Nuclear Information System (INIS)

    A new type of power supply system for a gyrotron with collector potential depression (CPD) to enhance gyrotron efficiency was developed. The power supply system is composed of a main power supply (MPS) and an acceleration power supply (APS). The APS which provides the stable high field to the magnetron injection gun (MIG) of the gyrotron is the key point of the system. The DC-DC converter technique is applied to the APS and it can output 100 kV of maximum voltage within ±0.5% stability and 300 mA of maximum current. The CPD gyrotron operation was successfully achieved with an efficiency of 48% and power of 350 kW for 5 s at 110 GHz. The stable gyrotron operation, without regulation of MPS, which provides the d.c. input power to the gyrotron, has been demonstrated by the combination of the APS and MPS. (orig.)

    The design and operation of the BNL multiparticle spectrometer are described. Also a formation experiment anti pp → n/sub c/ → final state was studied at 3.7 to 4.2 GeV/c tuning the total cm energy of the anti pp system to lie near the just below the J mass to search for the existence of a narrow peak (J/sup PC/ = O/sup -+ /GAMMAν several MeV). No outstanding peak is seen, but an approximate cross section limit is given in the region of a few microbarns. There is a clear K0 signal. Also a plot of the effective mass and missing mass for events with two neutral K's produced by 8.7-GeV/c π- on hydrogen is given

  13. Fully-automated field mapping of a dipole magnet of a multi-passage spectrometer (MPS)

    International Nuclear Information System (INIS)

    MLLTRAP is a Penning-trap mass-spectrometer facility, which is currently being commissioned at the Maier-Leibnitz Laboratory in Garching. Here, atomic mass values are determined by measuring cyclotron frequencies of stored ions in a strong magnetic field. In the future, highly-charged ions should be utilized for an improvement in the achievable mass accuracy. For this purpose, singly-charged ions will have to be injected into a charge-breeding device, such as an EBIT, and transferred back towards the Penning traps, while being q/A selected. To fulfill these tasks a multi-passage-spectrometer (MPS) is being built. It consists of a fast-ramping, round-pole dipole magnet with an electrostatic mirror system. A basic requirement for building the MPS is a detailed knowledge on the magnetic field produced by the magnet. It is necessary to simulate the trajectories of the ions and gain knowledge on the design and geometry of the electrostatic mirror system and the vacuum chamber. For this purpose, a robot was designed, which - powered by three step motors - measures the magnetic field fully automated. The robot moves a Hall probe within three dimensions with a resolution of 1 mm and an uncertainty of 0.5 mm. In this presentation, the development of the robot, its control and data acquisition via LabView and the results are presented.

  15. MPS views on population growth.

    Science.gov (United States)

    1997-09-01

    This article features the different views of Parliament members concerning the need in the reduction of population growth for development sustenance. Population growth would lead to environmental degradation, malnutrition, diseases, and high incidence of poverty. Furthermore, social problems arise like teenage pregnancies, and abuse of young girls. Suggestions on curtailing this problem as suggested by some of the parliament members includes educating people on issues of migration, family planning and reproductive health. Other members suggested on family planning legislation, like in the case of China where population explosion exists. Further, members thought that advocacy for population control such as condom usage targeting to couples having large families should be catered. However, this was denounced by some members as a failure and should not be sanctioned at large family couples but rather to husband with several wives. Finally, a compromised view was directed on population management with poverty alleviation involving the provision of amenities such as water, electricity, good roads, potable water, and income generating activities.

  16. Reservoir Modeling by Data Integration via Intermediate Spaces and Artificial Intelligence Tools in MPS Simulation Frameworks

    International Nuclear Information System (INIS)

    Conditioning stochastic simulations are very important in many geostatistical applications that call for the introduction of nonlinear and multiple-point data in reservoir modeling. Here, a new methodology is proposed for the incorporation of different data types into multiple-point statistics (MPS) simulation frameworks. Unlike the previous techniques that call for an approximate forward model (filter) for integration of secondary data into geologically constructed models, the proposed approach develops an intermediate space where all the primary and secondary data are easily mapped onto. Definition of the intermediate space, as may be achieved via application of artificial intelligence tools like neural networks and fuzzy inference systems, eliminates the need for using filters as in previous techniques. The applicability of the proposed approach in conditioning MPS simulations to static and geologic data is verified by modeling a real example of discrete fracture networks using conventional well-log data. The training patterns are well reproduced in the realizations, while the model is also consistent with the map of secondary data

  18. Capturing phenotypic heterogeneity in MPS I: results of an international consensus procedure

    2012-04-01

    Full Text Available Abstract Background Mucopolysaccharidosis type I (MPS I is traditionally divided into three phenotypes: the severe Hurler (MPS I-H phenotype, the intermediate Hurler-Scheie (MPS I-H/S phenotype and the attenuated Scheie (MPS I-S phenotype. However, there are no clear criteria for delineating the different phenotypes. Because decisions about optimal treatment (enzyme replacement therapy or hematopoietic stem cell transplantation need to be made quickly and depend on the presumed phenotype, an assessment of phenotypic severity should be performed soon after diagnosis. Therefore, a numerical severity scale for classifying different MPS I phenotypes at diagnosis based on clinical signs and symptoms was developed. Methods A consensus procedure based on a combined modified Delphi method and a nominal group technique was undertaken. It consisted of two written rounds and a face-to-face meeting. Sixteen MPS I experts participated in the process. The main goal was to identify the most important indicators of phenotypic severity and include these in a numerical severity scale. The correlation between the median subjective expert MPS I rating and the scores derived from this severity scale was used as an indicator of validity. Results Full consensus was reached on six key clinical items for assessing severity: age of onset of signs and symptoms, developmental delay, joint stiffness/arthropathy/contractures, kyphosis, cardiomyopathy and large head/frontal bossing. Due to the remarkably large variability in the expert MPS I assessments, however, a reliable numerical scale could not be constructed. Because of this variability, such a scale would always result in patients whose calculated severity score differed unacceptably from the median expert severity score, which was considered to be the 'gold standard'. Conclusions Although consensus was reached on the six key items for assessing phenotypic severity in MPS I, expert opinion on phenotypic severity at diagnosis proved to be highly variable. This subjectivity emphasizes the need for validated biomarkers and improved genotype-phenotype correlations that can be incorporated into phenotypic severity assessments at diagnosis.

    Master production schedule (MPS) plays an important role in an integrated production planning system. It converts the strategic planning defined in a production plan into the tactical operation execution. The MPS is also known as a tool for top management to control over manufacture resources and becomes input of the downstream planning levels such as material requirement planning (MRP) and capacity requirement planning (CRP). Hence, inappropriate decision on the MPS development may lead to i...

  20. Numerical analysis of fuel-coolant interactions in coolant injection mode using MPS

    International Nuclear Information System (INIS)

    The numerical method used in this study is the Moving Particle Semi-implicit (MPS) method which is based on moving particles and their interactions. Grids are not necessary, so that large fluid deformation can be calculated without numerical diffusion. Boiling and solidification models are developed for the MPS method. Melt injection is calculated considering boiling and solidification. Clusters of melt particles appear due to solidification. To understand the fundamental physics of the jet penetration, water jet injection into a pool of a denser fluid under non-boiling and isothermal conditions are calculated using the MPS method. The density ratio of the denser fluid to water is 1.88 (fluorinert) or 9.4 (anatomical alloy). The calculation results are compared with experiments, which were conducted in the ALPHA/MUSE facility at JAERI. In the calculation, air entrainment is observed as the experiments due to the jet penetration. However, the maximum jet penetration depth is shallower than the experiments. (author)

    International Nuclear Information System (INIS)

    The Taylor bubble rising in a vertical tube filled with liquid lead-bismuth eutectic was simulated based on MPS method. Several performed results including shape development, bubble rising terminal speed fitting line, and the thickness and axial velocity profile of the falling film were presented. The simulation results were compared with some experimental results from literature and reveal the corresponding laws obeyed by the terminal speed, velocity profile and film thickness. The computational results agree well with both theoretical analysis and experimental results, which demonstrates the reasonable selection of model as well as the accuracy and reliability of MPS method.

  3. Analytical model for reverse characteristics of 4H–SiC merged PN–Schottky (MPS) diodes

    International Nuclear Information System (INIS)

    A new analytical model for reverse characteristics of 4H–SiC merged PN–Schottky diodes (MPS or JBS) is developed. To accurately calculate the reverse characteristics of the 4H–SiC MPS diode, the relationship between the electric field at the Schottky contact and the reverse bias is analytically established by solving the cylindrical Poisson equation after the channel has pinched off. The reverse current density calculated from the Wentzel–Kramers–Brillouin (WKB) theory is verified by comparing it with the experimental result, showing that they are in good agreement with each other. Moreover, the effects of P-region spacing (S) and P-junction depth (Xj) on the characteristics of 4H–SiC MPS are analysed, and are particularly useful for optimizing the design of the high voltage MPS diodes.

    Mps1 is one of the several essential kinases whose activation is required for robust mitotic spindle checkpoint signalling. The activity of Mps1 is tightly regulated and increases dramatically during mitosis or in response to spindle damage. To understand the molecular mechanism underlying Mps1 regulation, we determined the crystal structure of the kinase domain of Mps1. The 2.7-{angstrom}-resolution crystal structure shows that the Mps1 kinase domain adopts a unique inactive conformation. Intramolecular interactions between the key Glu residue in the {alpha}C helix of the N-terminal lobe and the backbone amides in the catalytic loop lock the kinase in the inactive conformation. Autophosphorylation appears to be a priming event for kinase activation. We identified Mps1 autophosphorylation sites in the activation and the P+1 loops. Whereas activation loop autophosphorylation enhances kinase activity, autophosphorylation at the P+1 loop (T686) is associated with the active kinase. Mutation of T686 autophosphorylation site impairs both autophosphorylation and transphosphorylation. Furthermore, we demonstrated that phosphorylation of T676 may be a priming event for phosphorylation at T686. Finally, we identified two critical lysine residues in the loop between helices {alpha}EF and {alpha}F that are essential for substrate recruitment and maintaining high levels of kinase activity. Our studies reveal critical biochemical mechanisms for Mps1 kinase regulation.

    We calculate exactly the reduced density matrix of matrix product states (MPS). This result enables one to perform analytical studies of entanglement in MPS by elementary algebraic operations on matrices of small rank. We consider the MPS ground states of two anisotropic spin chains. One is a q-deformed Affleck-Kennedy-Lieb-Tasaki (AKLT) model and the other is a general spin-1 quantum antiferromagnet with nearest-neighbor interactions. Our analysis shows how anisotropy affects entanglement on different continuous parameter manifolds.

  7. Future opportunities for hadron spectroscopy at the MPS

    International Nuclear Information System (INIS)

    Before I go into detailed MPS experiments, I will give a summary of the status of lattice gauge calculations of glueball masses plus glueball and hybrid masses from the bag model, and the flux tube model. For the following discussion, I am going to assume that multi-quark states or molecules are best described in terms of the MIT bag model of Jaffe with its spectrum best defined by work done by R.L. Jaffe and F.E. Low using a method called The P-Matrix. Using this method one sees that all 4-quark states will appear as very broad continuum like effects that one would not associate with meson resonances, except for the S* and the ? which forms a very special threshold K/bar K/ bound systems. There is a possibility that the E(1420) may also be related to the J/sup PC/ = 1++, qq/bar q//bar q/ spectrum having its width narrowed by a final state interaction

    We prepared macro-porous silicon (MPS) by electrochemical corrosion in a double-tank cell on the surface of single-crystalline P-type silicon. Then, nano-WO3 films were deposited on MPS layers by DC facing target reactive magnetron sputtering. The morphologies of the MPS and WO3/MPS samples were investigated by using a field emission scanning electron microscope. The crystallization of WO3 and the valence of the W in the WO3/MPS sample were characterized by X-ray diffraction and X-ray photoelectron spectroscopy, respectively. The gas sensing properties of MPS and WO3/MPS gas sensors were thoroughly measured at room temperature. It can be concluded that: the WO3/MPS gas sensor shows the gas sensing properties of a P-type semiconductor gas sensor. The WO3/MPS gas sensor exhibits good recovery characteristics and repeatability to 1 ppm NO2. The addition of WO3 can enhance the sensitivity of MPS to NO2. The long-term stability of a WO3/MPS gas sensor is better than that of an MPS gas sensor. The sensitivity of the WO3/MPS gas sensor to NO2 is higher than that to NH3 and C2H5OH. The selectivity of the MPS to NO2 is modified by deposited nano-WO3 film.

    2015-09-01

    Full Text Available Mucopolysaccharidosis VI (MPS VI is an autosomal recessive inborn error of metabolism caused by mutations in the arylsulfatase B gene (ARSB and consequent deficient activity of ARSB, a lysosomal enzyme. We present here the results of a study undertaken to identify the mutations in ARSB in MPS VI patients in India. Around 160 ARSB mutations, of which just 4 are from India, have been reported in the literature. Our study covered nine MPS VI patients from eight families. Both familial mutations were found in seven families, and only one mutation was found in one family. Seven mutations were found — four novel (p.G38_G40del3, p.C91R, p.L98R and p.R315P, two previously reported from India (p.D53N and p.W450C, and one reported from outside India (p.R160Q. One mutation, p.W450C, was present in two families, and the other six mutations were present in one family each. Analysis of the molecular structure of the enzyme revealed that most of these mutations either cause loss of an active site residue or destabilize the structure of the enzyme. The only previous study on mutations in ARSB in Indian MPS VI patients, by Kantaputra et al. 2014 [1], reported four novel mutations of which two (p.D53N and p.W450C were found in our study as well. Till date, nine mutations have been reported from India, through our study and the Kantaputra study. Eight out of these nine mutations have been found only in India. This suggests that the population studied by us might have its own typical set of mutations, with other populations equally likely to have their own set of mutations.

    1999-01-01

    Planetary systems toward the Galactic Bulge can be detected through microlensing measurements. The microlensing planet search technique has some unique merits: low-mass planets can be detected from the ground; the Galactic family of planetary systems can be sampled unbiased; the time scale for the completion of each event is relatively short. The unambiguity of the underlying low-multiplicity point lenses is an indispensable element that allows robust interpretaion of the events. We have found the first circumbinary planet in the microlensing event MACHO-97-BLG-41. We have found evidence of a low mass planet (few Earths to Neptune mass) in a very high magnification event MACHO-98-BLG-35. We emphasize the necessity for coherent searches of microlensing planets with a network of instruments in the southern hemisphere. The network can also be vitally instrumental for follow-up observations of SN1a's and GRB's which share with microlensing planets the transiency as well as the clues to our quest of the origins.

    2007-06-01

    Mucopolysaccharidosis II (MPS II; Hunter syndrome) is an X-linked metabolic disorder caused by a deficiency of the lysosomal enzyme iduronate-2-sulfatase (I2S), which catalyzes the catabolism of glycosaminoglycans (GAG) by cleaving the O-linked sulfate from dermatan sulfate and heparan sulfate. Recently, enzyme replacement therapy (ERT) with recombinant human I2S (Elaprase (idursulfase), Shire Human Genetic Therapies, Inc.), has been approved in the US and European Union for the treatment and management of MPS II. The purpose of the studies presented here was to describe some of the preclinical development of idursulfase using the I2S knock-out mouse model of MPS II designed to study the effect of dose and various dosing regimens of idursulfase on urine and tissue GAG levels. Urine and tissue samples were collected prior to idursulfase treatment and periodically throughout each study and analyzed for GAGs. The presence of anti-idursulfase antibodies in the mice serum after idursulfase use was also determined. Results showed that idursulfase, at several doses and at several dosing frequencies, caused a reduction in tissue and urine GAG levels in a dose-dependent manner. These studies also demonstrated that after IV administration, idursulfase is biologically active in the IdS-KO mouse model and is transported to key target tissues, reaching the lysosomes in an active form, and degrading the accumulated GAG. In conclusion, these results indicated that ERT with idursulfase produced in a human cell line could be useful in the treatment and management of MPS II, and were used in the design of clinical studies to evaluate the efficacy of idursulfase in MPS II patients.

  15. Numerical analysis of molten core-concrete interaction using MPS method

    International Nuclear Information System (INIS)

    Moving particle semi-implicit (MPS) method uses particles for discretization of fluids. Governing equations are transformed to particle interactions. Grids are not necessary. This enables us to analyze multi-fluid and multi-phase flows with large deformation of interfaces. In the present study, a two-dimensional code is developed for molten core-concrete interaction (MCCI) based on the MPS method. Heat transfer is calculated without any specific correlations. Solid is simply represented by fixed particles. A particle can be changed to a moving (fluid) or fixed (solid) particle corresponding to its enthalpy. The developed code is applied to SWISS-2 experiment. The calculation geometry is x-y two dimensions though the experiment was r-z two dimensions. Nucleate boiling and radiation heat transfers are considered between the melt and the water pool. Only heat conduction is assumed among the melt pool, concrete and MgO (side wills). Natural convection in the melt pool is considered using Boussinesq's approximation. Gas release and volume contraction accompanied by the concrete ablation are ignored. Calculated heat flux to the water pool agrees well with the experiment, though the ablation speed in the concrete is a little slower. A stable crust is formed in a short time after water is poured in and the heat flux to the water pool rapidly decreases. The shape of the crust is like a bridge due to the natural convection in the melt pool. (author)

    2016-03-01

    A simple electrochemical biosensor for quantitative determination of carbamate pesticide was developed based on a sensing interface of citrate-capped gold nanoparticles (AuNPs)/(3-mercaptopropyl)-trimethoxysilane (MPS)/gold electrode (Au). The biosensor was fabricated by firstly assembling three-dimensional (3D) MPS networks on Au electrode and subsequently assembling citrate-capped AuNPs on 3D MPS network via AuS bond. The interface of AuNPs/MPS/Au was negatively charged originating from the citrate coated on AuNPs that would repulse the negatively charged ferricyanide ([Fe(CN)6](3-/4-)) to produce a negative response. In the presence of acetylcholinesterase (AChE) and acetylthiocholine (ATCl), the AChE catalyzes the hydrolysis of ATCl into positively charged thiocholine which would replace the citrate on AuNPs through the strong AuS bond and convert the negative charged surface to be positively charged. The resulted positively charged AuNPs/MPS/Au then attracted the [Fe(CN)6](3-/4-) to produce a positive response. Based on the inhibition of carbamate pesticides on the activity of AChE, the pesticide could be quantitatively determined at a very low potential. The linear range was from 0.003 to 2.00?M. The sensing platform was also proved to be suitable for carbamate pesticides detection in practical sample. PMID:26547618

It will select kinematic quantities unique to the reaction being studied, thereby permitting higher sensitivities and a reduction in data-processing cost for MPS experiments. The principles of operation for this trigger, and the results of simulations to assess its performance, are presented

    Nearly all children with MPS IVA develop skeletal deformities affecting the spine. At the atlanto-axial spine, odontoid hypoplasia occurs. GAG deposition around the dens, leads to peri-odontoid infiltration. Transverse/alar ligament incompetence causes instability. Atlanto-axial instability is associated with cord compression and myelopathy, leading to major morbidity and mortality. Intervention is often required. Does the presence of widened bullet shaped vertebra in platyspondily encroach o...

    Intracerebrospinal fluid (CSF) infusion of replacement enzyme is under evaluation for amelioration of disease-related symptoms and biomarker changes in patients with the lysosomal storage disorder mucopolysaccharidosis type IIIA (MPS IIIA; www.clinicaltrials.gov ; NCT#01155778; #01299727). Determining the optimal dose/dose-frequency is important, given the invasive method for chronically supplying recombinant protein to the brain, the main site of symptom generation. To examine these variables, we utilised MPS IIIA Huntaway dogs, providing recombinant human sulphamidase (rhSGSH) to young pre-symptomatic dogs from an age when MPS IIIA dog brain exhibits significant accumulation of primary (heparan sulphate) and secondary (glycolipid) substrates. Enzyme was infused into CSF via the cisterna magna at one of two doses (3 mg or 15 mg/infusion), with the higher dose supplied at two different intervals; fortnightly or monthly. Euthanasia was carried out 24 h after the final injection. Dose- and frequency-dependent reductions in heparan sulphate were observed in CSF and deeper layers of cerebral cortex. When we examined the amount of immunostaining of the general endo/lysosomal marker, LIMP-2, or quantified activated microglia, the higher fortnightly dose resulted in superior outcomes in affected dogs. Secondary lesions such as accumulation of GM3 ganglioside and development of GAD-reactive axonal spheroids were treated to a similar degree by both rhSGSH doses and dose frequencies. Our findings indicate that the lower fortnightly dose is sub-optimal for ameliorating existing and preventing further development of disease-related pathology in young MPS IIIA dog brain; however, increasing the dose fivefold but halving the frequency of administration enabled near normalisation of disease-related biomarkers.

    In developed nations, swallowing disorders and aspiration pneumonia have become serious problems. We developed a method to simulate the behavior of the organs involved in swallowing to clarify the mechanisms of swallowing and aspiration. The shape model is based on anatomically realistic geometry, and the motion model utilizes forced displacements based on realistic dynamic images to reflect the mechanisms of human swallowing. The soft tissue organs are modeled as nonlinear elastic material using the Hamiltonian MPS method. This method allows for stable simulation of the complex swallowing movement. A penalty method using metaballs is employed to simulate contact between organ walls and smooth sliding along the walls. We performed four numerical simulations under different analysis conditions to represent four cases of swallowing, including a healthy volunteer and a patient with a swallowing disorder. The simulation results were compared to examine the epiglottic downfolding mechanism, which strongly influences the risk of aspiration.

    Multi-task and real-time measurement of relative displacement is widely needed in the present industrial field. Existing measuring methods require complex preparation and data processing, or are unable meet the requirement of automation, multi-task and real-time. The instruments used to measure absolute coordinates are inefficiency because of the measured target is relative displacement. A new single-station wMPS (Workspace Measuring Position System) measurement method combined distance measurement is presented in this paper. It learns from measuring principle of total station, measures angle based on rotating scanning laser plane measuring method, and measures distance based on optoelectronic scanning multi-angle intersection location principle, uses the angle-length resection measuring method, builds a new mathematical model to measure the relative displacement of the target. The result of experiment proves that it increases measuring efficiency and achieves multi-task and real-time measurement of relative displacement.

    Full Text Available Membrane proteins (MPs are responsible for the interface between the exterior and the interior of the cell. These proteins are implicated in numerous diseases, such as cancer, cystic fibrosis, epilepsy, hyperinsulinism, heart failure, hypertension and Alzheimer's disease. However, studies on these disorders are hampered by a lack of structural information about the proteins involved. Structural analysis requires large quantities of pure and active proteins. The majority of medically and pharmaceutically relevant MPs are present in tissues at very low concentration, which makes heterologous expression in large-scale production-adapted cells a prerequisite for structural studies. Obtaining mammalian MP structural data depends on the development of methods that allow the production of large quantities of MPs. This review focuses on the different heterologous expression systems, and the purification strategies, used to produce large amounts of pure mammalian MPs for structural proteomics.

    2015-12-01

    Full Text Available Mucopolysaccharidosis (MPS is an inherited metabolic disease caused by deficiency of the enzymes needed for glycosaminoglycan (GAG degradation. MPS type I is caused by the deficiency of the lysosomal enzyme alpha-l-iduronidase and is classified into Hurler syndrome, Scheie syndrome, and Hurler–Scheie syndrome based on disease severity and onset. Cardiac complications such as left ventricular hypertrophy, cardiac valve disease, and coronary artery disease are often observed in MPS type I. Enzyme replacement therapy (ERT has been available for MPS type I, but the efficacy of this treatment for cardiac valve disease is unknown. We report on a 56-year-old female patient with attenuated MPS I (Scheie syndrome who developed aortic and mitral stenosis and coronary artery narrowing. The cardiac valve disease progressed despite ERT and she finally underwent double valve replacement and coronary artery bypass grafting. The pathology of the cardiac valves revealed GAG accumulation and lysosomal enlargement in both the mitral and aortic valves. Zebra body formation was also confirmed using electron microscopy. Our results suggest that ERT had limited efficacy in previously established cardiac valve disease. Early diagnosis and initiation of ERT is crucial to avoid further cardiac complications in MPS type I.

    Bubble dynamics is quite complicated in the field of two-phase hydrodynamics because the interfacial heat and mass transfer is comprehensively affected by various influencing factors. Bubble condensation can be either thermally controlled or inertia controlled. Inertia controlled bubble condensation indicates that considerable pressure difference exists between the steam bubble and ambient liquid. In this paper, the inertia controlled steam bubble condensation was simulated using moving particle semi-implicit (MPS) method. The spherical bubble is located in the center of the cylindrical pool which makes the possibility of 2-D axisymmetric computation. The lateral and bottom wall are set to be rigid insulated boundaries and the top is free surface boundary. The pool volume must be large enough to eliminate the effects by pool wall. The initial bubble pressure ranges from 0.48 MPa to 3.98 MPa, and the initial bubble diameter ranges from 2 mm to 5 mm, and the ambient water pressure and temperature is 0.1 MPa and 70 °C, respectively. The bubble dynamics during condensation was investigated and the influences of initial bubble pressure and diameter were obtained. The bubble deformation during condensation is shown in figure 1, and the variations of bubble diameters and pressures during condensation are shown in figures 2 and 3, respectively.

    Fermilab's Superconducting RF Beam Test Facility currently under construction will produce electron beams capable of damaging the acceleration structures and the beam line vacuum chambers in the event of an aberrant accelerator pulse. The accelerator is being designed with the capability to operate with up to 3000 bunches per macro-pulse, 5Hz repetition rate and 1.5 GeV beam energy. It will be able to sustain an average beam power of 72 KW at the bunch charge of 3.2 nC. Operation at full intensity will deposit enough energy in niobium material to approach the melting point of 2500 {\\deg}C. In the early phase with only 3 cryomodules installed the facility will be capable of generating electron beam energies of 810 MeV and an average beam power that approaches 40 KW. In either case a robust Machine Protection System (MPS) is required to mitigate effects due to such large damage potentials. This paper will describe the MPS system being developed, the system requirements and the controls issues under consideratio...

  14. Experiments and MPS analysis of stratification behavior of two immiscible fluids

    International Nuclear Information System (INIS)

    Highlights: • Improving numerical stability of MPS method. • Implicitly calculating viscous term in momentum equation for highly viscous fluids. • Validation of the enhanced MPS method by analyzing dam break problem. • Various stratification behavior analysis by experiments and simulations. • Sensitivity analysis of the effects of the fluid viscosity and density difference. - Abstract: Stratification behavior is of great significance in the late in-vessel stage of core melt severe accident of a nuclear reactor. Conventional numerical methods have difficulties in analyzing stratification process accompanying with free surface without depending on empirical correlations. The Moving Particle Semi-implicit (MPS) method, which calculates free surface and multiphase flow without empirical equations, is applicable for analyzing the stratification behavior of fluids. In the present study, the original MPS method was improved to simulate the stratification behavior of two immiscible fluids. The improved MPS method was validated through simulating classical dam break problem. Then, the stratification processes of two fluid columns and injected fluid were investigated through experiments and simulations, using silicone oil and salt water as the simulant materials. The effects of fluid viscosity and density difference on stratification behavior were also sensitively investigated by simulations. Typical fluid configurations at various parametric and geometrical conditions were observed and well predicted by improved MPS method

    To achieve a valid effect of wireless mesh networks against selfish nodes and selfish behaviors in the packets forwarding, an approach named mixed MPS-BNS strategy is proposed in this paper. The proposed strategy is based on the Maximum Payoff Strategy (MPS) and the Best Neighbor Strategy (BNS). In this strategy, every node plays a packet forwarding game with its neighbors and records the total payoff of the game. After one round of play, each player chooses the MPS or BNS strategy for certain probabilities and updates the strategy accordingly. In MPS strategy, each node chooses a strategy that will get the maximum payoff according to its neighbor's strategy. In BNS strategy, each node follows the strategy of its neighbor with the maximum total payoff and then enters the next round of play. The simulation analysis has shown that MPS-BNS strategy is able to evolve to the maximum expected level of average payoff with faster speed than the pure BNS strategy, especially in the packets forwarding beginning with a low cooperation level. It is concluded that MPS-BNS strategy is effective in fighting against selfishness in different levels and can achieve a preferable performance. PMID:23401672

    In the early days of general computer systems for science data processing, staff members working on NASA's data systems would most often be hired as mathematicians. Computer engineering was very often filled by those with electrical engineering degrees. Today, the Goddard Space Flight Center has special position descriptions for data scientists or as they are more commonly called: data systems engineers. These staff members are required to have very diverse skills, hence the need for a generalized position description. There is always a need for data systems engineers to develop, maintain and operate the complex data systems for Earth and space science missions. Today's data systems engineers however are not just mathematicians, they are computer programmers, GIS experts, software engineers, visualization experts, etc... They represent many different degree fields. To put together distributed systems like the NASA Earth Observing Data and Information System (EOSDIS), staff are required from many different fields. Sometimes, the skilled professional is not available and must be developed in-house. This paper will address the various skills and jobs for data systems engineers at NASA. Further it explores how to develop staff to become data scientists.

  17. Daily Democracy : A Comparative Study of British, Italian and Swedish MPs Use of Twitter in Non-election Periods

    DEFF Research Database (Denmark)

    Larson, Karin; Giro, Francesca

    Although the ubiquity of social media points to everyday concerns, when it comes to analysing its use by politicians research typically focuses on the exceptional, namely election campaigns. While this provides insight into a highly visible and strategically mediated phase of the political process, it ignores the communicative mundaneness of daily democracy. This paper accordingly in- vestigates and compares the ways in which members of parliament (MPs) in three European countries – Italy, Sweden and United Kingdom – utilize Twit- ter during off-peak periods, focusing on the extent to which social media are fostering a more ‘connected’ and reciprocal relationship between citizens and politicians. Throughout many Western democracies, research points to the in- creasing valorisation of Twitter as an informal, intimate and open space for (ev- eryday) political communication, raising important questions about what tweet- ing practices are particularly prominent and if and how connections with citizens are being cultivated. In order to begin addressing such questions, this paper uses hand-coded content analysis to examine tweeting behaviour during a two week non-election period. First, we map basic patterns of usage. Second, we analyse the types of tweets (e.g. retweet, @-reply); third, their function (e.g. self-promotion, critiquing, requesting input/support); fourth, interaction (whom MPs communicate with). Finally, we examine the content (the political/personal topics tweeted about). The unique comparative positioning of the study opens up analytical space for determining how national context may influence tweeting behaviour of MPs in diverging political systems. In light of this analysis, the pa- per explicates the interlinkages of political representation and inherent potential for bottom-up reciprocity between politicians and citizens engaging with social media. We dicuss our findings in light of ongoing debates about postmodern politics and the empowering potential of new media. We argue that social media practices may foster new (more personal, intimate) forms of connectivity and interaction between politicians and citizens.

  20. Myocardial Perfusion Tomoscintigraphy With 99mTc MIBI (SPECT MPS 99mTc MIBI) In The Assessment Of Myocardial Viability

    International Nuclear Information System (INIS)

    Prognosis of the patients with severe coronary artery disease is highly dependent on the degree of left ventricular dysfunction. Impaired contractile performance at rest is not necessarily due to Irreversible tissue damage but may relate to the 'hibernating' myocardium which has been defined as potentially reversible, chronic contractile dysfunction during prolonged, painless ischemia. Recovery of function may occur after successful revascularization only in the presence of substantial amount of viable myocardium. The development of highly precise and predictable diagnostic methods for the identification of viable myocardium and postoperative functional improvement is crucial for reasonable preoperative selection of the patients. Detection of hibernated myocardium Is a real diagnostic challenge when FDG-Fl8 PET, as the most accurate method for myocardial viability assessment is not available and Tl 201, as already established myocardial viability marker is not routinely used. Interest for the 99mTc labeled complexes, most often 99mTc MIBI, as proved myocardial perfusion but not yet viability tracer is constantly increasing, supported by the widespread availability of this radioisotope, its better imaging and radio dosimetric properties when compared to Ti 201. The aim of this study was to evaluate the diagnostic value of different SPECT MIBI Tc99m myocardial perfusion scintigraphy (MPS) modalities performed at rest and after nitrate administration, in the detection of myocardial viability (MV) arid to compare it with rest-redistribution TI 201 MPS (R-Red) and with the control SPECT MPS Tc99m MIBI study after revascularization. In a prospective study, 176 patients (34-77yrs, 25 female, 151 male), with angiographically proved coronary artery disease, most of them with previous myocardial infarction (143/176p (81%),>6 months) and LV dysfunction (110/176p (62%), EFG-MPS 41+/-16%) underwent ECG Gated SPECT MPS Tc 99m MIBI at rest and after s.l. administration of 0,5 mg Nitroglycerin (NTG). 20/176 p were examined also by TI 201 R-Red study and 20/176p were reevaluated after revascularization. Qualitative and quantitative analysis of rest, post-NTG and TI 201 Rest-Redistribution perfusion images (QL,QN) and functional analysis of rest and post-NTG Gated study (G) was done, using 17 segment model, grouped also according to vascular territories and 5-point scoring system for assessment of perfusion (0-normal, 1-mild,2-moderate,3-severe hypoperfusion, 4-absent perfusion) and wall motion (0-normal,l-mild,2-severe hypo kinetic, 3-akinetic,4-dyskinetic). A segment was predeterminated to be viable if the segment score was ?2 by perfusion (>50% photon activity by circumferential profiles) and ?2 by C-CG qated SPECT analysis (wall motion +/-, wall thickening-). Summed segment viability scores, total and separate for particular territory were. calculated and used to predict overall and territory viability. In a group of 176 pts, from a total of 2992 analyzed myocardial segments, 47% were nonviable by QL-Rest analysis, 31% by QN-Rest (p2) 25% by G-Rest (p2), 36% by QL-Rest-Red (p=0.3 vs. QL-Rest, ?2), 18% by QN-Rest-Red (p=04 vs. QN-Rest, ?2),), 33% by QL-NTG (p2), 19% by QN-NTG (p2), 16% by G-NTG (p=0.08 vs. QN-NTG, ?2), 28% by QL-NTG-Red (P=0.33 vs. QL-NTG, ?2), and 17% by QN-NTG-Red (p=0.4 vs. QN- NTG, ?2). Similar relation among different modalities was also observed during the assessment of total viability score: 26+/-9.1 by QN-Rest, 21.8+/-8.9 by G-Rest (p<0.01 vs. QN-Rest), 20.2+/-9.9 by QN-NTG (p<0.0l vs. G-Rest) and 16.7+/-9.4 by NTG-G (p<0.001 vs QN-NTG). Compared with TI 201 R-Red the sensitivity, specificity, positive and negative predictive values and accuracy for SPECT MPS Tc99m MIBI modalities were: 73%,100%,100%,37,5%,76% for QL-Rest, 84%,96%,99%,49%,86% for QN-Rest, 93,5%,81%,97%,67% 92% for G-Rest, 86%,94%, 99%,52%,87% for QL-NTG, 97%,90%,98%,81%,96% for QN-NTG and 97%,75%,96%82%,94% for G-NTG.

    Type I mucopolysaccharidosis (MPS I) is an autosomal recessive lysosomal storage disorder with neurological features. Humans and laboratory animals with MPS I exhibit various white matter abnormalities involving the corpus callosum and other regions. In this study, we first validated a novel MRI technique, entitled Relaxation Along a Fictitious Field in the rotating frame of rank n (RAFFn), as a measure of myelination and dysmyelination in mice. We then examined differences between MPS I mice and heterozygotes using RAFF5 and histology. RAFF5 (i.e., RAFFn with n = 5) relaxation time constants were highly correlated with histological myelin density (R2 = 0.68, P<0.001), and RAFF5 clearly distinguished between the hypomyelinated and dysmyelinated shiverer mouse and the wild-type mouse. Bloch-McConnell theoretical analysis revealed slower exchange correlation times and smaller exchange-induced relaxation rate constants for RAFF4 and RAFF5 compared to RAFF1-3, T1?, and T2?. These data suggest that RAFF5 may assess methylene protons in myelin lipids and proteins, though other mechanisms (e.g. detection of myelin-bound water) may also explain the sensitivity of RAFF5 to myelin. In MPS I mice, mean RAFF5 relaxation time constants were significantly larger for the striatum (P = 0.004) and internal capsule (P = 0.039), and marginally larger for the fornix (P = 0.15). Histological assessment revealed no differences between MPS I mice and heterozygotes in myelin density or corpus callosum thickness. Taken together, these findings support subtle dysmyelination in the brains of mice with MPS I. Dysmyelination may result from myelin lipid abnormalities caused by the absence of ?-L-iduronidase. Our findings may help to explain locomotor and cognitive deficits seen in mice with MPS I. PMID:25680196

    2013-01-01

    The density matrix renormalization group (DMRG) has become an indispensable numerical tool to find exact eigenstates of finite-size quantum systems with strong correlation. In the fields of condensed matter, nuclear structure and molecular electronic structure, it has significantly extended the system sizes that can be handled compared to full configuration interaction, without losing numerical accuracy. For quantum chemistry (QC), the most efficient implementations of DMRG require the incorporation of particle number, spin and point group symmetries in the underlying matrix product state (MPS) ansatz, as well as the use of so-called complementary operators.

If a symmetry is non-abelian, the Wigner-Eckart theorem allows to factorize a tensor into a Clebsch-Gordan coefficient and a reduced tensor.

  5. Numerical analysis of crust formation in molten core-concrete interaction using MPS method

    International Nuclear Information System (INIS)

    A two-dimensional code is developed for molten core-concrete interaction (MCCI) based on Moving Particle Semi-implicit (MPS) method. Heat transfer is calculated without any specific correlations. A particle can be changed to a moving (fluid) or fixed (solid) particle corresponding to its enthalpy, which provide the phase change model for particles. The phase change model is verified by one-dimensional test calculations. Nucleate boiling and radiation heat transfers are considered between the core debris and the water pool. The developed code is applied to SWISS-2 experiment in which stainless steel is used as the melt material. Calculated heat flux to the water pool agrees well with the experiment, though the ablation speed in the concrete is a little slower. A stable crust is formed in a short time after water is poured in and the heat flux to the water pool rapidly decreases. MACE-M0 using corium is also analyzed. The ablation speed of concrete is slower than that of SWISS-2 because of low heat conduction in corium. An unlimited geometry is analyzed by setting the cyclic boundary condition on the sides. When the crust is broken by the decomposition gas, heat transfer to the water pool is kept high for a longer time because the crust re-formation is delayed. (author)

  6. A DSP-Based Beam Current Monitoring System for Machine Protection Using Adaptive Filtering

    International Nuclear Information System (INIS)

    The CEBAF accelerator at Jefferson Lab is currently using an analog beam current monitoring (BCM) system for its machine protection system (MPS), which has a loss accuracy of 2 micro-amps. Recent burn-through simulations predict catastrophic beam line component failures below 1 micro-amp of loss, resulting in a blind spot for the MPS. Revised MPS requirements target an ultimate beam loss accuracy of 250 nA. A new beam current monitoring system has been developed which utilizes modern digital receiver technology and digital signal processing concepts. The receiver employs a direct-digital down converter integrated circuit, mated with a Jefferson Lab digital signal processor VME card. Adaptive filtering is used to take advantage of current-dependent burn-through rates. Benefits of such a system include elimination of DC offsets, generic algorithm development, extensive filter options, and interfaces to UNIX-based control systems

    Full Text Available The aim of this study was to prepare light-cured dental composites and to evaluate their physical, chemical and mechanical properties. Experimental composites were prepared from 2, 2 bis [4-(2-hidroxy 3-metacriloxypropoxi) phenyl] propane (Bis-GMA), tetraethyleneglycol dimethacrylate (TEEGDMA), 3-me [...] thacryloxypropyl trimethoxysilane (MPS) and a hybrid filler consisting of quartz and colloidal silica particles (Aerosil 90). The initiation system was based on the pair Camphorquinone (CQ) / N, N dimethylaminoethylmethacrylate (DMAEMA). The experimental composites and a commercial dental composite used as reference (Charisma®) were submitted to determinations of depth of cure, water absorption and solubility, compressive and diametral tensile strengths, and elastic modulus, according to the indications of the ISO standards. The experimental resins presented adequate values for most of the analyzed properties, except for compressive strengths. In the Bis-GMA/ MPS/quartz-aerosil composite a better integration between filler and matrix was observed. The Bis-GMA/TEEGDMA/quartz-aerosil composite showed the best performance in regards to depth of cure, solubility in water, diametral tensile strength and elastic modulus. The properties of this composite were better than those of the commercial reference material, except for compressive strength.

    The density matrix renormalization group (DMRG) has become an indispensable numerical tool to find exact eigenstates of finite-size quantum systems with strong correlation. In the fields of condensed matter, nuclear structure and molecular electronic structure, it has significantly extended the system sizes that can be handled compared to full configuration interaction, without losing numerical accuracy.

The symmetries introduce a sparse block structure in the MPS ansatz and in the intermediary contracted tensors. If a symmetry is non-abelian, the Wigner-Eckart theorem allows to factorize a tensor into a Clebsch-Gordan coefficient and a reduced tensor. In addition, the fermion signs have to be carefully tracked. Because of these challenges, implementing DMRG efficiently for QC is not straightforward. Efficient and freely available implementations are therefore highly desired. In this work we present CheMPS2, our free open-source spin-adapted implementation of DMRG for ab initio QC. Around CheMPS2, we have implemented the augmented Hessian Newton-Raphson complete active space self-consistent field method, with exact Hessian. The bond dissociation curves of the 12 lowest states of the carbon dimer were obtained at the DMRG(28 orbitals, 12 electrons, DSU(2) = 2500)/cc-pVDZ level of theory. The contribution of 1 s core correlation to the X1?g+ bond dissociation curve of the carbon dimer was estimated by comparing energies at the DMRG(36o, 12e, DSU(2) = 2500)/cc-pCVDZ and DMRG-SCF(34o, 8e, DSU(2) = 2500)/cc-pCVDZ levels of theory.

    The intelligent transportation system has generated a strong need for the development of intelligent camera systems to meet the requirements of sophisticated applications, such as electronic toll collection (ETC), traffic violation detection and automatic parking lot control. In order to achieve the highest levels of accuracy in detection, these cameras must have high speed electronic shutters, high resolution, high frame rate, and communication capabilities. A progressive scan interline transfer CCD camera, with its high speed electronic shutter and resolution capabilities, provides the basic functions to meet the requirements of a traffic camera system. Unlike most industrial video imaging applications, traffic cameras must deal with harsh environmental conditions and an extremely wide range of light. Optical character recognition is a critical function of a modern traffic camera system, with detection and accuracy heavily dependent on the camera function. In order to operate under demanding conditions, communication and functional optimization is implemented to control cameras from a roadside computer. The camera operates with a shutter speed faster than 1/2000 sec. to capture highway traffic both day and night. Consequently camera gain, pedestal level, shutter speed and gamma functions are controlled by a look-up table containing various parameters based on environmental conditions, particularly lighting. Lighting conditions are studied carefully, to focus only on the critical license plate surface. A unique light sensor permits accurate reading under a variety of conditions, such as a sunny day, evening, twilight, storms, etc. These camera systems are being deployed successfully in major ETC projects throughout the world.

    Mucopolysaccharidosis type IIIA (MPS-IIIA) or Sanfilippo A syndrome is a lysosomal storage genetic disease that results from the deficiency of the N-sulfoglucosamine sulfohydrolase (SGSH) protein, a sulfamidase required for the degradation of heparan sulfate glycosaminoglycans (GAGs). The accumulation of these macromolecules leads to somatic organ pathologies, severe neurodegeneration and death. To assess a novel gene therapy approach based on prolonged secretion of the missing enzyme by the liver, mediated by hydrodynamic gene delivery, we first compared a kanamycin and an antibiotic-free expression plasmid vector, called pFAR4. Thanks to the reduced vector size, pFAR4 derivatives containing either a ubiquitous or a liver-specific promoter mediated a higher reporter gene expression level than the control plasmid. Hydrodynamic delivery of SGSH-encoding pFAR4 into MPS-IIIA diseased mice led to high serum levels of sulfamidase protein that was efficiently taken up by neighboring organs, as shown by the correction of GAG accumulation. A similar reduction in GAG content was also observed in the brain, at early stages of the disease. Thus, this study contributes to the effort towards the development of novel biosafe non-viral gene vectors for therapeutic protein expression in the liver, and represents a first step towards an alternative gene therapy approach for the MPS-IIIA disease.

  14. Power Systems Development Facility

    International Nuclear Information System (INIS)

    The objective of the PSDF would be to provide a modular facility which would support the development of advanced, pilot-scale, coal-based power systems and hot gas clean-up components. These pilot-scale components would be designed to be large enough so that the results can be related and projected to commercial systems. The facility would use a modular approach to enhance the flexibility and capability for testing; consequently, overall capital and operating costs when compared with stand-alone facilities would be reduced by sharing resources common to different modules. The facility would identify and resolve technical barrier, as well as-provide a structure for long-term testing and performance assessment. It is also intended that the facility would evaluate the operational and performance characteristics of the advanced power systems with both bituminous and subbituminous coals. Five technology-based experimental modules are proposed for the PSDF: (1) an advanced gasifier module, (2) a fuel cell test module, (3) a PFBC module, (4) a combustion gas turbine module, and (5) a module comprised of five hot gas cleanup particulate control devices. The final module, the PCD, would capture coal-derived ash and particles from both the PFBC and advanced gasifier gas streams to provide for overall particulate emission control, as well as to protect the combustion turbine and the fuel cell

(KBR) Transport Gasifier train with a Siemens Westinghouse Power Corporation (SW) particle filter system at the Power Systems Development Facility (PSDF) located in Wilsonville, Alabama. The Transport Gasifier is an advanced circulating fluidized-bed reactor designed to operate as either a combustor or a gasifier using a particulate control device (PCD). While operating as a gasifier, either air or oxygen can be used as the oxidant. Test run TC12 began on May 16, 2003, with the startup of the main air compressor and the lighting of the gasifier start-up burner. The Transport Gasifier operated until May 24, 2003, when a scheduled outage occurred to allow maintenance crews to install the fuel cell test unit and modify the gas clean-up system. On June 18, 2003, the test run resumed when operations relit the start-up burner, and testing continued until the scheduled end of the run on July 14, 2003. TC12 had a total of 733 hours using Powder River Basin (PRB) subbituminous coal. Over the course of the entire test run, gasifier temperatures varied between 1,675 and 1,850 F at pressures from 130 to 210 psig.

    A new fine coal dewatering technology has been developed and tested in the present work. The work was funded by the Solid Fuels and Feedstocks Grand Challenge PRDA. The objective of this program was to 'develop innovative technical approaches to ensure a continued supply of environmentally sound solid fuels for existing and future combustion systems with minimal incremental fuel cost.' Specifically, this solicitation is aimed at developing technologies that can (i) improve the efficiency or economics of the recovery of carbon when beneficiating fine coal from both current production and existing coal slurry impoundments and (ii) assist in the greater utilization of coal fines by improving the handling characteristics of fine coal via dewatering and/or reconstitution. The results of the test work conducted during Phase I of the current project demonstrated that the new dewatering technologies can substantially reduce the moisture from fine coal, while the test work conducted during Phase II successfully demonstrated the commercial viability of this technology. It is believed that availability of such efficient and affordable dewatering technology is essential to meeting the DOE's objectives.

    Mucopolysaccharidosis (MPS) II is an X-linked metabolic disorder caused by dysfunction of iduronate-2-sulfatase (I2S). This abnormality causes the progressive accumulation of incompletely degraded glycosaminoglycans (GAGs) in the lysosomes. The auditory characteristics of MPS II in mouse models have not been reported. In this study, we evaluated the auditory characteristics of the MPS II in IDS knock-out (IDS-KO) mice. In addition, the effect of enzyme replacement therapy (ERT) on hearing was studied. The IDS-KO mice had normal histology of the cochlea and retained good hearing at 7 weeks of age. However, at 17 weeks of age, the hearing thresholds of the IDS-KO mice were elevated and exudates were found in the middle ear. The hearing thresholds of the enzyme-treated IDS-KO (IDS-ERT) mice were similar to the wild-type (WT) mice at 17 weeks. Moreover, the microstructure of the inner ear was similar to the IDS-KO by transmission electron microscopy. The histology findings indicated that the microstructure of the inner ear was similar in comparisons between IDS-KO and IDS-ERT mice, even after 10 weeks of treatment. However, the hearing deficits in the MPS II mouse model can be prevented if ERT is started before the onset of hearing impairment. PMID:22847837

    In this study, the rigid body dynamics coupled moving particle semi-implicit (RD-MPS) method was used to simulate a plunging liquid jet penetrating into a denser liquid pool. The phenomenon is related to fuel-coolant interactions (FCI) during severe accidents in nuclear power plants when coolant water is forcedly injected into a melt pool. A numerical particle method like MPS enables to simulate the complex multiphase flow in that significant deformation of fluids occurs due to its inherent grid less algorithm. However, the MPS method alone cannot continue the calculation for a long time as shown in the Ikea's work due to the large deformation of fluid surfaces and the difference in both liquid densities. In the RD-MPS method, the rigid body dynamics was coupled with the moving particle semi-implicit method to increase the overall stability of calculations and to calculate the multi-phase behavior of fluids. We performed two and three dimensional calculations to simulate jet penetration behaviors in a denser liquid pool, and the result was in good agreement with that of experiment. The simulation results suggested that the coupled model be useful in simulating dynamic interactions of multi-phase incompressible fluids as well as that the 3-D simulation for the plunging jet in a confined geometry predicted better agreement with experimental results than the 2-D simulation did.

    Particle dissipation and mixing in liquid are common multiphase phenomena not only in nature and but also in industrial processes. Also, It is one of important phenomena in nuclear safety analysis on severe accidents associated with the coolability of the corium debris bed, in which the characteristics of the porous corium debris bed such as local porosity distribution, debris bed configuration, debris size distribution, porous structure etc., determined by the corium jet breakup, precipitation, and mixing processes are considered to be of importance. Therefore, we developed a new computational tool, called ADDA (Analysis of Debris Dynamics and Agglomeration), based on an enhanced MPS (Moving Particle Semi-implicit) algorithm (Park, 2011) to understand the complex debris dissipation and mixing phenomena and identify the roles of the debris characteristics in the process and verified against the QUEOS experiment (Meyer, 1996; 1997) performed at FzK in Germany

The transport reactor is an advanced circulating fluidized-bed reactor designed to operate as either a combustor or a gasifier using one of two possible particulate control devices (PCDs). The transport reactor was operated as a pressurized gasifier during GCT3. GCT3 was planned as a 250-hour test run to commission the loop seal and continue the characterization of the limits of operational parameter variations using a blend of several Powder River Basin coals and Bucyrus limestone from Ohio. The primary test objectives were: (1) Loop Seal Commissioning--Evaluate the operational stability of the loop seal with sand and limestone as a bed material at different solids circulation rates and establish a maximum solids circulation rate through the loop seal with the inert bed. (2) Loop Seal Operations--Evaluate the loop seal operational stability during coal feed operations and establish maximum solids circulation rate. Secondary objectives included the continuation of reactor characterization, including: (1) Operational Stability--Characterize the reactor loop and PCD operations with short-term tests by varying coal feed, air/coal ratio, riser velocity, solids circulation rate, system pressure, and air distribution. (2) Reactor Operations--Study the devolatilization and tar cracking effects from transient conditions during transition from start-up burner to coal. Evaluate the effect of process operations on heat release, heat transfer, and accelerated fuel particle heat-up rates. Study the effect of changes in reactor conditions on transient temperature profiles, pressure balance, and product gas composition. (3) Effects of Reactor Conditions on Syngas Composition--Evaluate the effect of air distribution, steam/coal ratio, solids circulation rate, and reactor temperature on CO/CO{sub 2} ratio, H{sub 2}/converted carbon ratio, gasification rates, carbon conversion, and cold and hot gas efficiencies. Test run GCT3 was started on December 1, 2000, with the startup of the thermal oxidizer fan, and was completed on February 1, 2001. This test was conducted in two parts; the loop seal was commissioned during the first part of this test run from December 1 through 15, which consisted of hot inert solids circulation testing. These initial tests provided preliminary data necessary to understand different parameters associated with the operation and performance of the loop seal. The loop seal was tested with coal feed during the second part of the test run and additional data was gathered to analyze reactor operations and to identify necessary modifications to improve equipment and process performance. In the second part of GCT3, the gasification portion of the test, from January 20 to February 1, 2001, the mixing zone and riser temperatures were varied between 1,675 and 1,825 F at pressures ranging from 200 to 240 psig. There were 306 hours of solid circulation and 184 hours of coal feed attained in GCT3.

    The Personnel Protection System (PPS), Machine Protection System (MPS) and Timing System (TS) of control system for Linear IFMIF Prototype Accelerator are critical systems for not only operation but also safety of accelerator. Then, the control system and accelerator subsystem (Injector, RFQ and etc.) communicate by hardwired signals. And, the adjustments and the definitions of interface and sequence function are important. In addition, under the control system and the accelerator subsystem are linked actually, the interface test for them has to be performed in EU before its shipment to Rokkasho, because it has a high risk to take long time to improve them after some problems about interface are found at Rokkasho. Then, to achieve the reliable functions for PPS, MPS and TS, we began developing the test benches of these systems using PLC MPS units, TS modules and etc. which are adopted at actual equipments from the start of the control system development. Next, we shipped these developed test benchies to EU (CEA, Saclay) and we connected them with Injector. And, we performed the interface tests during Injector test at Saclay. In this paper, the results of interface test at Saclay between Injector and PPS, MPS and TS are presented. (author)

  11. Numerical analysis of jet injection mechanism of fuel-coolant interactions using MPS

    International Nuclear Information System (INIS)

    The numerical method used in this study is Moving Particle Semi-implicit (MPS) method which is based on moving particles and their interactions. Grids are not necessary, so that large fluid deformation can be calculated without numerical diffusion. To understand the fundamental physics of the jet penetration, water jet injection into a pool of a denser fluid under non-boiling and isothermal conditions is calculated using the MPS method. The density ratio of the denser fluid (Fluorinert) to water is 1.88. The calculation results are compared with experiments which were conducted in the ALPHA/MUSE facility at JAERI. In three-dimensional calculation, the penetration behavior agrees with the experiment. It is found that the jet penetration process is divided to two stages and, at the first stage, the coolant jet can penetrate deeper than existing correlations of breakup length. (author)

    This study presents an accurate and robust boundary model, the explicitly represented polygon (ERP) wall boundary model, to treat arbitrarily shaped wall boundaries in the explicit moving particle simulation (E-MPS) method, which is a mesh-free particle method for strong form partial differential equations. The ERP model expresses wall boundaries as polygons, which are explicitly represented without using the distance function. These are derived so that for viscous fluids, and with less computational cost, they satisfy the Neumann boundary condition for the pressure and the slip/no-slip condition on the wall surface. The proposed model is verified and validated by comparing computed results with the theoretical solution, results obtained by other models, and experimental results. Two simulations with complex boundary movements are conducted to demonstrate the applicability of the E-MPS method to the ERP model.

    Full Text Available Mucopolysaccharidosis type I (MPS I) is a rare lysosomal disorder caused by deficiency of alph-L-iduronidase. Few clinical trials have assessed the effect of enzyme replacement therapy (ERT) for this condition. We conducted an exploratory, open-label, non-randomized, multicenter cohort study of pati [...] ents with MPS I. Data were collected from questionnaires completed by attending physicians at the time of diagnosis (T1; n = 34) and at a median time of 2.5 years later (T2; n = 24/34). The 24 patients for whom data were available at T2 were allocated into groups: A, no ERT (9 patients; median age at T1 = 36 months; 6 with severe phenotype); B, on ERT (15 patients; median age at T1 = 33 months; 4 with severe phenotype). For all variables in which there was no between-group difference at baseline, a delta of ;±20% was considered clinically relevant. The following clinically relevant differences were identified in group B in T2: lower rates of mortality and reported hospitalization for respiratory infection; lower frequency of hepatosplenomegaly; increased reported rates of obstructive sleep apnea syndrome and hearing loss; and stabilization of gibbus deformity. These changes could be due to the effect of ERT or of other therapies which have also been found more frequently in group B. Our findings suggest MPS I patients on ERT also receive a better overall care. ERT may have a positive effect on respiratory morbidity and overall mortality in patients with MPS I. Additional studies focusing on these outcomes and on other therapies should be performed.

    State-of-the-art (SOA) carbon dioxide (CO2) reduction technology for the International Space Station produces methane as a byproduct. This methane is subsequently vented overboard. The associated loss of hydrogen ultimately reduces the mass of oxygen that can be recovered from CO2 in a closed-loop life support system. As an alternative to SOA CO2 reduction technology, NASA is exploring a Series-Bosch system capable of reducing CO2 with hydrogen to form water and solid carbon. This results in 100% theoretical recovery of oxygen from metabolic CO2. In the past, Bosch-based technology did not trade favorably against SOA technology due to a high power demand, low reaction efficiencies, concerns with carbon containment, and large resupply requirements necessary to replace expended catalyst cartridges. An alternative approach to Bosch technology, labeled "Series-Bosch," employs a new system design with optimized multi-stage reactors and a membrane-based separation and recycle capability. Multi-physics modeling of the first stage reactor, along with chemical process modeling of the integrated system, has resulted in a design with potential to trade significantly better than previous Bosch technology. The modeling process and resulting system architecture selection are discussed.

    Full Text Available Aneuploidy has been recognized as a common characteristic of cancers. Aneuploidy frequently results from errors of the mitotic checkpoint, the major cell cycle control mechanism that acts to prevent chromosome missegregation. Mutation of the genes that control chromosome segregation during mitosis may explain the high rate of chromosomal instability and aneuploidy, a characteristic of most solid tumors, including glioblastoma (GBM (Gordon et al., 2012 [1]; Singh et al., 2012 [2]. Monopolar spindle 1 (MPS1 is an essential spindle assembly checkpoint kinase that is overexpressed in several human cancers (Kilpinen et al., 2010 [3]; Mills et al., 1992 [4]; Yuan et al., 2006 [5]. In our previous publication, we have shown the role of MPS1 kinase in DNA repair and enhanced radiosensitivity in GBM (Maachani et al., 2015 [6]. Here, we provide methodological and analytical details of that study, to compare mRNA expression profile of siMPS1-silenced U251 cells with untransfected control, and siRNA control (siNeg at 6, 24, and 48 h after transfection.

    In order to increase the yield of the ceramic precursors, copolymers of polycarbosilane (PCS) and {gamma}-methacryloxypropyltrimethoxy silane ({gamma}-MPS) were synthesized by hydrosilylation with platinum catalyst. The structures of PCS-co-MPS ceramic precursors were investigated by using FT-IR and {sup 1}H-NMR spectrometers. The syntheses of ceramic precursors were confirmed by monitoring the change of the absorption bands appearing at 2100, 1720, 1640, 1170, 1130 cm{sup -1} on the FT-IR spectra. The syntheses of ceramic precursors were also confirmed by the presence of peaks at 4.1, 3.5, 1.8 ppm on the {sup 1}H-NMR spectra. The conversion of PCS-co-MPS copolymers was around 87.5% and 18.2% higher than that of the pure PCS. After the heat-treatment at 1500{sup o} C, the crystalline peaks for {beta}-SiC were observed at -60, -109 pp, on the {sup 29}Si-NMR spectra, and at 2{theta}=35{sup o}, 59{sup o} and 71{sup o} on the X-ray spectra, respectively. It showed the conversion of ceramic precursors to crystalline {beta}-SiC. 18 refs., 8 figs.

    Compatibility between an arcjet propulsion system and a communications satellite was verified by testing a Government-furnished, 1.4 kW hydrazine arcjet system with the FLTSATCOM qualification model satellite in a 9.1-meter (30-foot) diameter thermal-vacuum test chamber. Background pressure was maintained at 10(exp -5) torr during arcjet operation by cryopumping the thruster exhaust with an array of 5 K liquid helium cooled panels. Power for the arcjet system was obtained from the FLTSATCOM battery simulator. Spacecraft telemetry was monitored during each thruster firing period. No changes in telemetry data attributable to arcjet operation were detected in any of the tests. Electromagnetic compatibility data obtained included radiated emission measurements, conducted emission measurements, and cable coupling measurements. Significant noise was observed at lower frequencies. Above 500 MHz, radiated emissions were generally within limits, indicating that communication links at S-band and higher frequencies will not be affected. Other test data taken with a diagnostic array of calorimeters, radiometers, witness plates, and a residual gas analyzer evidenced compatible operation, and added to the data base for arcjet system integration. Two test series were conducted. The first series only included the arcjet and diagnostic array operating at approximately 0.1 torr background pressure. The second series added the qualification model spacecraft, a solar panel, and the helium cryopanels. Tests were conducted at 0.1 torr and 10(exp-5) torr. The arcjet thruster was canted 20 degrees relative to the solar panel axis, typical of the configuration used for stationkeeping thrusters on geosynchronous communications satellites.

    2004-01-01

    Full Text Available Young and adult Wistar rats were submitted to total splenectomy and compared to animals not submitted to any surgical manipulation in order to evaluate the phagocytic function of spleen. The animals were infected with Escherichia coli labeled with technetium-99m and killed 20 minutes later. Liver, lung, spleen and a blood clot sample were taken. No significant differences were found in the percentage of bacterial radioactivity uptake in mononuclear phagocyte system (MPS organs in young and adult splenectomized rats. However, phagocytosis index by macrophages of MPS organs was smaller in splenectomized animals than in control group. Splenectomized rats were associated with a higher blood bacterial radioactivity uptake than animals of the control group (p<0.0001 due to a larger bacterial remnant in the bloodstream. This finding suggested that some failure in the MPS occurred in the absence of the spleen, demonstrating the need to develop alternative surgical techniques for total splenectomy.

    A KRS is suggested through design requirement analysis of the buffer and the canister which are the constituent of disposal system engineered barrier and HLW management plans are proposed. In the aspect of radionuclide retention capacity, the thickness of the buffer is determined 0.5m, the shape to be disc and ring and the dry density to be 1.6 g/cm{sup 3}. The maximum temperature of the buffer is below 100 .deg. which meets the design requirement. And bentonite blocks with 5 wt% of graphite showed more than 1.0 W/mK of thermal conductivity without the addition of sand. The result of the thermal analysis for proposed double-layered buffer shows that decrease of 7 .deg. C in maximum temperature of the buffer. For the disposal canister, the copper for the outer shell material and cast iron for the inner structure material is recommended considering the results analyzed in terms of performance of the canisters and manufacturability and the geochemical properties of deep groundwater sampled from the research area with granite, salt water intrusion, and the heavy weight of the canister. The results of safety analysis for the canister shows that the criticality for the normal case including uncertainty is the value of 0.816 which meets subcritical condition. Considering nation's 'Basic Plan for Electric Power Demand and Supply' and based on the scenario of disposing CANDU spent fuels in the first phase, the disposal system that the repository will be excavated in eight phases with the construction of the Underground Research Laboratory (URL) beginning in 2020 and commissioning in 2040 until the closure of the repository is proposed. Since there is close correlation between domestic HLW management plans and front-end/back-end fuel cycle plans causing such a great sensitivity of international environment factor, items related to assuring the non-proliferation and observing the international standard are showed to be the influential factor and acceptability of HLW management plans to be the influential factor of making decision for social acceptability of nuclear power.

  5. Development of a multifunctional particle spectrometer for space radiation imaging

    International Nuclear Information System (INIS)

    For future exploration of the solar system, the European Space Agency (ESA) is planning missions to Mercury (BepiColombo), the Sun (SolarOrbiter) and to the moons of Jupiter and Saturn. The expected intensity of radiation during such missions is hazardous for the scientific instruments and the satellite. To extend the lifetime of the satellite and its payload a multifunctional particle spectrometer (MPS) is being developed. The basic function of the MPS is to send an alarm signal to the satellite control system during periods of high radiation. In addition the MPS is a scientific instrument that will unfold the composition of the different contributing particles on-line by the dE/dx versus E method. The energy spectrum and angular distribution of the particles will be recorded as well. This article describes the main requirements and the base line design for the MPS. A readout scheme consisting of a 32 channel ASIC from IDEAS is proposed and the signal filtering algorithm will run on a digital signal processor based on FPGA technology. Results are shown from prototype calibration studies with a proton beam

  6. Incremental value of 24-hour delayed imaging in 201Tl stress myocardial perfusion studies (MPS) with an 'early rest reinjection' protocol

    International Nuclear Information System (INIS)

    Full text: One hundred patients (pts) undergoing stress MPS had 24 h imaging for fixed defects at 4 h delayed imaging. 53 had prior myocardial infarction (MI) and 71 were males. Stress employed isotonic exercise with dipyridamole (0.56 mg kg-1) infusion in 57 pts, exercise alone in 33 and dipyridamole alone in 10. All pts with stress defects had rest-reinjection of 40 MBq of 201Tl after stress imaging had been completed, and most had sublingual nitrate therapy 10 min before reinjection. MPS from the 100 pts (15% of total) were read without clinical data, using a 20 segment scoring system. 51 pts showed -2 segments improvement between 4 and 24 h scores, but 22 pts had shown reversibility between stress and 4 h imaging and the further change did not alter interpretation. The other 29 pts (group A) showed clinically important change in 24 h scores, leaving 71 pts without clinical change (group B). Segmental improvement between 4 and 24 h in group A was 4.62 ± 2.18 and 1.18 ± 1.48 in group B (P = 0.02). Group A stress defect scores were not greater (10.90 ± 3.60) or more severe (3.72 ± 3.06) than in group B (8.92 ± 4.34 and 2.79 ± 3.11); 18 group A pts had MI compared with 38 group B pts. No significant correlation was found between improved 4-24 h scores and parameters of stress-LV dysfunction. There is benefit from 24 h, 201TI MPS in patients with persisting 4 h defects, despite early rest-reinjection and acute nitrate therapy

  11. Numerical analysis of freezing controlled penetration behavior of the molten core debris in an instrument tube with MPS

    International Nuclear Information System (INIS)

    Highlights: • The EPRI-3 melt solidification test was successfully analyzed by MPS code. • Analysis of the solidification behavior of molten UO2 and Fe in BWR instrument tube. • The melt had solidified and plugged the instrument tube in all the calculations. • Typical melt solidification behavior in instrument tube was revealed by MPS method. - Abstract: The freezing controlled penetration behavior of the molten core debris in the BWR instrument tube had been analyzed with a two dimensional geometry under severe accident conditions using Moving Particle Semi-implicit (MPS) method. The change of melt viscosity with temperature in the phase transition region was taken into account in the present MPS method. Accordingly, in order to improve the computation speed of such highly viscous fluid, the implicit calculation scheme was employed to solve the viscous term in this study. The surface tension model based on the inter-particle potential force was incorporated in the MPS method to track the melt leading front more accurately. The present MPS method was validated first by simulating the experiment of molten aluminum oxide penetrating in a prototypical PWR instrument tube which was performed by EPRI. The comparison of the predicted penetration length and the measured results showed a good agreement selecting a parameter. Then the penetration and solidification behaviors of molten stainless steel and uranium dioxide in the BWR instrument tube were simulated under a wide parametric range. The computational results showed that the melt penetration length increased with the melt superheat, and the melt had plugged the tube in all simulations. The melt flow resistance increased due to the formation of the crust on the tube surface and the increase of melt viscosity in the phase transition region. The present results indicated that the typical melt penetration and solidification behavior in the instrument tube was successfully revealed by MPS method

  12. Exercise tolerance test (ett) or myocardial perfusion scan (mps) - what to choose in patients of ischaemic heart disease (ihd)

    International Nuclear Information System (INIS)

    Objective: To evaluate the validity of exercise tolerance test (ETT) with treadmill exercise in the diagnosis and follow-up of ischaemic heart disease (IHD), taking myocardial perfusion scan (MPS) as standard. Study Design: Retrospective, validation study. Place and Duration of Study: Nuclear Medical Centre (NMC) Armed Forces Institute of Pathology (AFIP), Rawalpindi, Pakistan, from 1 January to 31 December 2009. Patients and Methods: One hundred and nineteen patients (88 males, 31 females), referred for MPS; were selected through non-probability, consecutive sampling. Patients of all ages and gender, fit to undertake treadmill exercise, were included. Patients with contraindications to ETT, like unstable angina, conduction abnormalities, etc., or those who had taken a beta blocker within the preceding 24 hours, were excluded. ETT through treadmill exercise was done, followed by MPS with single photon emission computed tomography (SPECT) technique, using Thallium-201 or Technetium-99 m 2-methoxy-isobutyl-isonitrile (MIBI). ETT was interpreted as positive or negative for ischaemia, with borderline changes considered positive. MPS was interpreted as positive or negative for ischaemia. Validity of ETT was evaluated in terms of sensitivity (Sn), specificity (Sp), and positive and negative predictive value (PPV and NPV), taking MPS as standard. Results: Sensitivity of ETT was found to be 77.5% and specificity was 43.6%. PPV was 73.8% and NPV was 48.6%. Out of a total (n) of 119 patients, true positive (TP) cases were 62, true negative (TN) 17, false positive (FP) 22 and false negative (FN) 18. Conclusions: ETT is an acceptably sensitive but non-specific test for evaluating myocardial ischaemia, with adequate PPV but low NPV, when validating it against MPS. Replacing the MPS with ETT, in the diagnosis and follow-up of IHD, is thus, not prudent. ETT can be useful as a screening test. (author)

  15. Numerical Analysis on the Vortex Pattern and Flux Particle Dispersion in KR Method Using MPS Method

    Science.gov (United States)

    Hirata, N.; Xu, Y.; Anzai, K.

    2015-06-01

    The mechanically-stirring vessel is widely used in many fields, such as chemical reactor, bioreactor, and metallurgy, etc. The type of vortex mode that formed during impeller stirring has great effect on stirring efficiency, chemical reacting rate and air entrapment. Many efforts have been made to numerically simulate the fluid flow in the stirring vessel with classical Eulerian method. However, it is difficult to directly investigate the vortex mode and flux particle dispersion. Therefore, moving particle semi-implicit (MPS) method, which is based on Lagrangian method, is applied to simulate the fluid flow in a KR method in this practice. Top height and bottom heights of vortex surface in a steady state under several rotation speed was taken as key parameters to compare the results of numerical and published results. Flux particle dispersion behaviour under a rotation speed range from 80 to 480 rpm was also compared with the past study. The result shows that the numerical calculation has high consistency with experimental results. It is confirmed that the calculation using MPS method well reflected the vortex mode and flux particle dispersion in a mechanically-stirring vessel.

    Mucopolysaccharidosis IVA (MPS IVA; Morquio A syndrome) is a lysosomal storage disorder caused by deficiency of N-acetylgalactosamine-6-sulfate sulfatase, which results in systemic accumulation of glycosaminoglycans (GAGs), keratan sulfate and chondroitin-6-sulfate. Accumulation of these GAGs causes characteristic features as disproportionate dwarfism associated with skeletal deformities, genu valgum, pigeon chest, joint laxity, and kyphoscoliosis. However, the pathological mechanism of systemic skeletal dysplasia and involvement of other tissues remain unanswered in the paucity of availability of an autopsied case and successive systemic analyses of multiple tissues. We report here a 20-year-old male autopsied case with MPS IVA, who developed characteristic skeletal features by the age of 1.5 years and died of acute respiratory distress syndrome five days later after occipito-C1-C2 cervical fusion. We pathohistologically analyzed postmortem tissues including trachea, lung, thyroid, humerus, aorta, heart, liver, spleen, kidney, testes, bone marrow, and lumbar vertebrae. The postmortem tissues relevant with clinical findings demonstrated 1) systemic storage materials in multiple tissues beyond cartilage, 2) severely vacuolated and ballooned chondrocytes in trachea, humerus, vertebrae, and thyroid cartilage with disorganized extracellular matrix and poor ossification, 3) appearance of foam cells and macrophages in lung, aorta, heart valves, heart muscle, trachea, visceral organs, and bone marrow, and 4) storage of chondrotin-6-sulfate in aorta. This is the first autopsied case with MPS IVA whose multiple tissues have been analyzed pathohistologically and these pathological findings should provide a new insight into pathogenesis of MPS IVA.

    José Sixto, B.A.

    2011-01-01

    Full Text Available In a technologically and sociologically advanced society, the organizations that do not use the new media and the cyber communication techniques are probably doomed to failure. In this virtual sphere the social networks constitute a suitable resource and channel for the implementation of political marketing 2.0, as it provides a scenario where the interaction with users is possible. From this perspective, we verified their presence of the 350 members of the Spanish Congress on Facebook, the country’s most popular social network, in order to establish the predominant typologies, updating frequency, contents, resources, and the types of information posted in this spaces.This article also examines the interactivity of MPs in what we have termed Commitment 2.0: political communication in personal contexts such as social networks requires going from the participatory attitude to the participatory action; that is, to accept the interaction 2.0 as the correct behaviour on the network.

  3. A Study on the Management of Micropollutants in Water System Considering Climate Change and other Potential Effects

    International Nuclear Information System (INIS)

    In this study, the management polices of micropollutants (MPs) were reviewed and the future management strategy was discussed considering climate change and etc. In Korea, the investigation of drinking water has been actively carried out for the priority contaminants as well as MPs. Recently river and lake waters have been also examined for MPs. However, the coverage and depth of the investigation is limited. Moreover, climate change is likely to increase air, water temperature and it will affect the hydrological cycle. Such changes may increase the residual concentrations of MPs in water system. As water reuse increases, the residual MPs of the recycled water may create public concerns. Thus, in a viewpoint of the precautionary principle, more stringent management of MPs is recommended for the drinking water and the body-contact water use. For the surface water, more studies are necessary to understand the ecological risk by MPs

  4. Development of teleoperated cleanup system

    International Nuclear Information System (INIS)

    This report describes the development of a teleoperated cleanup system for use in a highly radioactive environment of DFDF(DUPIC Fuel Demonstration Facility) at KAERI where direct human access to the in-cell is strictly limited. The teleoperated cleanup system was designed to remotely remove contaminants placed or fixed on the floor surface of the hot-cell by mopping them with wet cloth. This cleanup system consists of a mopping slave, a mopping master and a control console. The mopping slave located at the in-cell comprises a mopping tool with a mopping cloth and a mobile platform, which were constructed in modules to facilitate maintenance. The mopping master that is an input device to control the mopping slave has kinematic dissimilarity with the mopping slave. The control console provides a means of bilateral control flows and communications between the mopping master and the mopping slave. In operation, the human operator from the out-of-cell performs a series of decontamination tasks remotely by manipulating the mopping slave located in-cell via a mopping master, having a sense of real mopping. The environmental and mechanical design considerations, and control systems of the developed teleoperated cleanup system are also described

  7. Development of pipe layout system

    International Nuclear Information System (INIS)

    In the plant design carried out so far, the process up to final drawings has been the repetition of the correction of drawings. This is because the space as the object of design is finite, and it is difficult to lay many pipes efficiently. Especially in nuclear power plants, the quantity of materials required for ensuring the safety and quality control is enormous, and only the skilled engineers having rich experience have become unable to deal with it. The model engineering using plastic models has been adopted, but still there are problems. In order to solve this problem, the development of the system for unitarily managing the various design information of plants with a computer, checking up various design with this information, automatically outputting design drawings and management data, and heightening the quality of design, synchronizing the progress, increasing the speed and saving the labor of design was carried out. This system is versatile and can be used for all plants. The emphasis in the development was placed on compact data structure, rapid picture processing and easy operation. The present status of design and the automation, the basic design of the system, the function of the system, the internal expression of models, the method of picture processing, and the results of application are reported.

    York, David W.; Mackin, Michael A.; Liszka, Kathy J.; Lichter, Michael J.

    2004-01-01

    Telemedicine is taking a step forward with the efforts of team members from the NASA Glenn Research Center, the MetroHealth campus of Case Western University, and the University of Akron. The Arrhythmia Monitoring System is a completed, working test bed developed at Glenn that collects real-time electrocardiogram (ECG) signals from a mobile or homebound patient, combines these signals with global positioning system (GPS) location data, and transmits them to a remote station for display and monitoring. Approximately 300,000 Americans die every year from sudden heart attacks, which are arrhythmia cases. However, not all patients identified at risk for arrhythmias can be monitored continuously because of technological and economical limitations. Such patients, who are at moderate risk of arrhythmias, would benefit from technology that would permit long-term continuous monitoring of electrical cardiac rhythms outside the hospital environment. Embedded Web Technology developed at Glenn to remotely command and collect data from embedded systems using Web technology is the catalyst for this new telemetry system (ref. 1). In the end-to-end system architecture, ECG signals are collected from a patient using an event recorder and are transmitted to a handheld personal digital assistant (PDA) using Bluetooth, a short-range wireless technology. The PDA concurrently tracks the patient's location via a connection to a GPS receiver. A long distance link is established via a standard Internet connection over a 2.5-generation Global System for Mobile Communications/General Packet Radio Service (GSM/GPRS)1 cellular, wireless infrastructure. Then, the digital signal is transmitted to a call center for monitoring by medical professionals.

    Serrano, Daniel; Maña, Antonio; Llarena, Rafael; Crespo, Beatriz Gallego-Nicasio; Li, Keqin

    Traditionally, security patterns have successfully been used to describe security and dependability. In the SERENITY Project the notion of security and dependability (S&D) pattern has been extended to exact specifications of re-usable security mechanisms for Ambient Intelligence (AmI) systems. These S&D Patterns include information on the security properties satisfied by the solution and on the context conditions to be fulfilled. This chapter presents the development of applications supported by SERENITY. In the context of SERENITY we refer to these applications as Serenity-aware applications. Firstly, this chapter presents the Serenity-aware application design using S&D Artefacts. Secondly, it proposes a Java Application Programming Interface (API) to be used in the application development. And, finally, it introduces the development of an example Serenity-aware application.

    Full Text Available An adequate logistics information system provides real time automated data processing, distribution and of information according to Terrain Commander's requirements, which leads to timely fulfillment of logistic demands of units. SAP ERP The SAP ERP application is the integrated (ERP software capable of working with complex organisational structures, personnel, equipment, and finance. It enables planning and combining forces for every type of operations. The system also enables the determination of the readiness status of modelled forces. ISL The Information System for Logistics (ISL is a comprehensive information system of the Ministry of Defence (MoD and the Army of the Czech Republic that covers many areas: acquisition, supply, ammunition and equipment maintenance, logistics, etc. The ISL provides support for military logistics in all important areas of consumer and acquisition logistics, satisfaying all kinds of Defence Forces needs in the country and abroad. LOGFAS The information system LOGFAS comprises Logistics Database (LOGBASE, Movement and Transportation software (M&T, Allied Command Europe Resource Optimisation Software System (ACROSS and Logistic Reporting System (LOGREP. The Logistics Database LOGBASE represents a logistics information source and also a database related to assets, forces, geography, infrastructure, targets, supplies, movements and medical data. The main software tools which rely on the LOGBASE are M&T, ACROSS and LOGREP. GCSS-Army The original impetus to create the SALE came in the mid-90s when the United States Department of Defense (DoD started a logistics modernisation programme. One of tasks was to build The Single Army Logistics Enterprise (SALE for the purpose of covering the whole organisational structure of the DoD. There are three components of the SALE: GCSS-Army, PLM+ and LMP. Each of them uses the commercial Enterprise Resource Planning SAP Software with a Web access. The main component, GCSS-Army (Global Combat Support System-Army Field/Tactical, is intended for the tactical level and it will replace 14 tactical logistics information systems and connect them with the rest of the information environment. Tendencies in the development of logistics information systems In line with the presented information solutions, it is possible to extract relevant conclusions about tendencies in the development of these types of systems all around the world. These conclusions should be implemented, through adequate principles, into domestic software development. Three main tendencies are visible in modern solutions: using centralised databases, integration of existing separated software solutions, and connecting previously autonomus systems. Conclusion In accordance with present time requirements, logistic support should be realised as close as possible to the origin of a logistic need, in real time and adequately. Information systems enable real time delivery of information needed for a quality logistic support in all phases of operations as well as for a faster generation of all types of documents.

    We developed a novel poly(lactic-co-glycolic acid)-based, microparticle (MP) system providing concurrent delivery of multiple encapsulated immuno-suppressive factors and antigen, for in vivo conditioning of dendritic cells (DCs) toward a tolerance promoting pathway. Subcutaneous administration prevents onset of type 1 diabetes (T1D) in NOD mice. Two MP sizes were made: phagocytosable MPs were fabricated encapsulating vitamin D3 or insulin B(9-23) peptide, while unphagocytosable MPs were fabricated encapsulating TGF-?1 or GM-CSF. The combination of Vit D3/TGF-?1 MPs confers an immature and LPS activation-resistant phenotype to DCs, and MP-delivered antigen is efficiently and functionally presented. Notably, two subcutaneous injections into 4week old NOD mice using the combination of MPs encapsulating Vit D3, Ins B, TGF-?1 and GM-CSF protected 40% of mice from T1D development, significant in comparison to the control. This work represents one of the first applications of a biomaterial-based, MP vaccine system to successfully prevent autoimmune diabetes. PMID:25842187

    Advances in genetic engineering have generated great interest in biotechnology systems. Modern fermentation processes have a more scientific basis and can be optimized more quickly by utilizing instrumentation and control technology that permits increasing yield and product quality. The automation technology, to a large extent, can determine the degree of success of growing microorganisms. The automation system in modern biotechnology facilities includes a number of leading technologies such as sensors, indicators, data acquisition, distributed control, programmable control, communications, data base management, on-line data analysis techniques and application software. Modern computer systems have made fermentation processes easier and more accurate by performing tasks such as on-line analysis, statistical process control and supervisory control, while microprocessor-based distributed process controllers perform direct digital control, batch and sequencing control. This paper addresses technical issues related to the development of instrumentation and control systems that integrate these technologies through methodologies that permit the timely generation of the documentation and drawings that specify the control system for procurement, installation, commissioning, validation and operation.

    2007-10-15

    Design, high-voltage test, and installation of 6 MW ICRF heating system for KSTAR is completed. The antenna demonstrated satisfactory standoff at high voltages up to 41 kV for 300 sec. The result indicates good power handling capabilities of the antenna as high as 10 MW/m2. This power density is equivalent to RF power coupling of 6 MW into a 4 {omega}/m target plasma, and is typical of advanced tokamak heating scenarios. In addition, vacuum feed through, DC break, and liquid stub developed for 300 sec operation are installed, as well as a 2 MW, 30-60MHz transmitter. The transmitter successfully produced output powers of 600 kW continuously, 1.5{approx}1.8 MW for 300 sec, and 2 MW for 100 msec or shorter pulses. A realtime control system based on DSP and EPICS is developed, installed, and tested on the ICRF system. Initial results from feasibility study indicate that the present antenna and the transmission lines could allow load-resilient operation on KSTAR. Until the KSTAR tokamak start to produce plasmas in 2008, however, hands-on operational experiences are obtained from participating in ICRF heating experiments at ASDEX and DIII-D tokamaks arranged through international cooperation.

  14. Expert system development (ESD) shell

    International Nuclear Information System (INIS)

    An Expert System Development (ESD) Shell design implementation is desribed in detail. The shell provides high-level generic facilities for Knowledge Representation (KR) and inferencing and tools for developing user interfaces. Powerful set of tools in the shell relieves much of the programming burden in the ES development. The shell is written in PROLOG under IBM PC/AT. KR facilities are based on two very powerful formalisms namely, frames and rules. Inference Engine (IE) draws most of its power from unification and backward reasoning strategy in PROLOG. This basic mechanism is enhanced further by incorporating both forward and backward chaining of rules and frame-based inferencing. Overall programming style integrates multiple paradigms including logic, object oriented, access-oriented and imperative programming. This permits ES designer a lot of flexibility in organizing inference control. Creation and maintainance of knowledge base is a major activity. The shell, therefore, provides number of facilities to simplify these tasks. Shell design also takes note of the fact that final success of any system depends on end-user satisfaction and hence provides features to build use-friendly interfaces. The shell also provides a set of interfacing predicates so that it can be embedded within any PROLOG program to incorporate functionalilty of the shell in the user program.

  15. StaMPS Improvement for Deformation Analysis in Mountainous Regions: Implications for the Damavand Volcano and Mosha Fault in Alborz

    Directory of Open Access Journals (Sweden)

    Sanaz Vajedian

    2015-06-01

    Full Text Available Interferometric Synthetic Aperture Radar (InSAR capability to detect slow deformation over terrain areas is limited by temporal decorrelation, geometric decorrelation and atmospheric artefacts. Multitemporal InSAR methods such as Persistent Scatterer (PS-InSAR and Small Baseline Subset (SBAS have been developed to deal with various aspects of decorrelation and atmospheric problems affecting InSAR observations. Nevertheless, the applicability of both PS-InSAR and SBAS in mountainous regions is still challenging. Correct phase unwrapping in both methods is hampered due to geometric decorrelation in particular when using C-band SAR data for deformation analysis. In this paper, we build upon the SBAS method implemented in StaMPS software and improved the technique, here called ISBAS, to assess tectonic and volcanic deformation in the center of the Alborz Mountains in Iran using both Envisat and ALOS SAR data. We modify several aspects within the chain of the processing including: filtering prior to phase unwrapping, topographic correction within three-dimensional phase unwrapping, reducing the atmospheric noise with the help of additional GPS data, and removing the ramp caused by ionosphere turbulence and/or orbit errors to better estimate crustal deformation in this tectonically active region. Topographic correction is done within the three-dimensional unwrapping in order to improve the phase unwrapping process, which is in contrast to previous methods in which DEM error is estimated before/after phase unwrapping. Our experiments show that our improved SBAS approach is able to better characterize the tectonic and volcanic deformation in the center of the Alborz region than the classical SBAS. In particular, Damavand volcano shows an average uplift rate of about 3 mm/year in the year 2003–2010. The Mosha fault illustrates left-lateral motion that could be explained with a fault that is locked up to 17–18 km depths and slips with 2–4 mm/year below that depth.

    Delivery system of insulin is vital for its acceptance and adherence to therapy for achieving the glycemic targets. Enormous developments have occurred in the delivery system of insulin during the last twenty years and each improvement was aimed at two common goals: patients convenience and better glycemic control. Till to date, the various insulin delivery systems are: syringes/vials, injection aids, jet injectors, transmucosal delivery, transdermal delivery, external insulin infusion pump, implantable insulin pumps, insulin pens and insulin inhalers. Syringe/vial is the oldest and conventional method, still widely used and relatively cheaper. Modern plastic syringes are disposable, light weight with microfine needle for patients convenience and comfort. Oral route could be the most acceptable and viable, if the barriers can be overcome and under extensive trial. Insulin pen device is an important milestone in the delivery system of insulin as it is convenient, discrete, painless, attractive, portable with flexible life style and improved quality of life. More than 80% of European diabetic patients are using insulin pen. Future digital pen will have better memory option, blood glucose monitoring system, insulin dose calculator etc. Insulin infusion pump is a good option for the children, busy patients with flexible lifestyle and those who want to avoid multiple daily injections. Pulmonary route of insulin delivery is a promising, effective, non-invasive and acceptable alternative method. Exubera, the world first insulin inhaler was approved by FDA in 28 January 2006. But due to certain limitations, it has been withdrawn from the market in October 2007. The main concern of inhaled insulin are: long term pulmonary safety issues, cost effectiveness and user friendly device. In future, more acceptable and cost effective insulin inhaler will be introduced. Newer avenues are under extensive trial for better future insulin delivery systems. PMID:18285745

    T. R. Duhl

    2013-04-01

    Full Text Available A pollen model that simulates the timing and production of wind-dispersed allergenic pollen by terrestrial, temperate vegetation has been developed to quantify how pollen occurrence may be affected by climate change and to investigate how pollen can interact with anthropogenic pollutants to affect human health. The Simulator of the Timing and Magnitude of Pollen Season (STaMPS model is driven by local meteorological conditions and is designed to be sensitive to climate shifts, as well as flexible with respect to the vegetation species and plant functional types (trees, grasses, etc. represented and the climate zones simulated. The initial focus for the model is the simulation of the pollen emission potential of important allergenic tree and grass species that typically flower between March–June in Southern California (S. CA, which is characterized by moderate Mediterranean and oceanic climate zones as well as regions of arid desert and arid steppe. Vegetation cover and species composition data are obtained from numerous datasets and a database of allergenic vegetation species, their pollen production potential and relative allergenicities has been developed. For the selected allergenic species and spring-early summer simulation period, temperature is the main driver controlling the timing of pollen release, while precipitation (and temperature, for some species controls the magnitude of pollen produced. The model provides species-specific pollen potential maps for each day of the simulation period; these are then used by a pollen transport model to simulate ambient pollen concentrations as described in a companion paper (Zhang et al., 2013a, which also presents model evaluation results for the S. CA model domain. The STaMPS model was also used to quantify the possible impact of climate change on pollen season under the IPCC SRES A1B scenario as simulated by the ECHAM5 global climate model. Current (1995–2004 and future (2045–2054 meteorological conditions downscaled using the Weather Research and Forecasting (WRF model were used to drive STaMPS and generate estimates of the relative magnitude and timing of pollen season for important allergenic tree and grass species that bloom from March through June in a larger domain that covers all of CA and Nevada. Differences in the simulated timing and magnitude of pollen season for the selected allergenic species under current and future climate scenarios are presented. The results suggest that across all of the simulated species, pollen season starts an average of 5–6 days earlier under predicted future climatic conditions with an associated average annual domain-wide temperature increase of about 1°C compared to simulated current conditions. Differences in the amount of pollen produced under the two scenarios vary by species and are affected by the selected simulation period (1 March–30 June. Uncertainties associated with the STaMPS model and future model development plans are also discussed.

    2001-01-01

    The Compact Microscope Imaging System (CMIS) is a diagnostic tool with intelligent controls for use in space, industrial, medical, and security applications. The CMIS can be used in situ with a minimum amount of user intervention. This system, which was developed at the NASA Glenn Research Center, can scan, find areas of interest, focus, and acquire images automatically. Large numbers of multiple cell experiments require microscopy for in situ observations; this is only feasible with compact microscope systems. CMIS is a miniature machine vision system that combines intelligent image processing with remote control capabilities. The software also has a user-friendly interface that can be used independently of the hardware for post-experiment analysis. CMIS has potential commercial uses in the automated online inspection of precision parts, medical imaging, security industry (examination of currency in automated teller machines and fingerprint identification in secure entry locks), environmental industry (automated examination of soil/water samples), biomedical field (automated blood/cell analysis), and microscopy community. CMIS will improve research in several ways: It will expand the capabilities of MSD experiments utilizing microscope technology. It may be used in lunar and Martian experiments (Rover Robot). Because of its reduced size, it will enable experiments that were not feasible previously. It may be incorporated into existing shuttle orbiter and space station experiments, including glove-box-sized experiments as well as ground-based experiments.

  19. Computer aided training system development

    International Nuclear Information System (INIS)

    The first three phases of Training System Development (TSD) -- job and task analysis, curriculum design, and training material development -- are time consuming and labor intensive. The use of personal computers with a combination of commercial and custom-designed software resulted in a significant reduction in the man-hours required to complete these phases for a Health Physics Technician Training Program at a nuclear power station. This paper reports that each step in the training program project involved the use of personal computers: job survey data were compiled with a statistical package, task analysis was performed with custom software designed to interface with a commercial database management program. Job Performance Measures (tests) were generated by a custom program from data in the task analysis database, and training materials were drafted, edited, and produced using commercial word processing software

    International Nuclear Information System (INIS)

    Conventional or external beam radiotherapy, has been a viable alternative for cancer treatment. Although this technique is effective, its use is limited if the patient has multiple malignant lesions (metastases). An alternative approach is based on the design of radiopharmaceuticals that, to be administered in the patient, are directed specifically toward the target cell producing a selective radiation delivery. This treatment is known as targeted radiotherapy. We have summarized and discussed some results related to our investigations on the development of targeted radiotherapy systems, including aspects of internal dosimetry

The Aging system will not handle naval fuel, DOE HLW, MCOs, or DOE SNF since those materials will be delivered to the repository in a state and sequence that allows them to be placed into waste packages for emplacement. Some CSNF from nuclear reactors, especially CSNF that is thermally too hot for emplacement underground, will need to be aged at the repository

  2. ADASAGE, ADA Application Development System

    International Nuclear Information System (INIS)

    1 - Description of program or function: ADASAGE is an application development system designed to facilitate rapid and professional construction of applications written in Ada on microcomputers. ADASAGE applications may vary in size from small to large multi-program systems. ADASAGE consists of a collection of re-usable libraries for database management and form and report processing utilities having the following capabilities: basic universal type and function definitions; sequential file input/output; terminal and file input/output; DOS system command execution; data movement and fill; string manipulation; math libraries; bit manipulation; a relational database utility; data validation; menu form and window procedures; report generation; sort/merge, time, and date functions; sound production; editing; and index rebuilding. Each of the capabilities is integrated to allow the development of an efficient system. As an application is designed and developed, the desired ADASAGE capabilities are chosen and included along with any requirements unique to that application. 2 - Method of solution: All ADASAGE applications which use the database, forms (windows, menus, etc.), or reporting functions require a file with a suffix of .DFL. This file contains the database schema, the various forms and windows, and report definitions. The THOR editor is used to create and maintain the .DFL file. This editor operates on a file with the suffix .SRC and creates and edits schemes, forms, and report formats and compile the .SRC file into the .DFL file used by the application. The application will have unique requirements not satisfied by the selected utilities of ADASAGE. The code for these along with the code necessary to import and use the selected ADASAGE utilities constitutes the programmed application. The completed application system will contain the .DFL file produced by the THOR editor, the required ADASAGE utilities, and the programmed application. During the course of normal database development and use, restructuring and/or rebuilding of database files may be required if the schema for a record is modified (new fields are added, changed, or deleted and new keys selected, etc.), or if the index file for a relation becomes damaged or is destroyed. Program REBUILD performs this task. The rebuilding process is invoked by supplying both an old .DFL file name identifying the schema definition under which the current data was written and a current .DFL file name identifying the new schema definition to which the current database must be changed. REBUILD compares the old and current schema definitions for a relation, adjusts the database files accordingly, and re-tags the database files with the new version so that access with the new schema is allowed. The index file for the relation is then rebuilt, and any unused space within the database files removed. 3 - Restrictions on the complexity of the problem: Maxima for each ADASAGE database are: 4,294,967,000 records (tuples) per record size; 32,000 bytes record (tuple) size; 32,000 fixed-length field (attribute size); 4,294,967,000 variable-length field (attribute) size; 1,000 relations (flat files); 1,000 joined relations; 1,000 views; 500 fields (attributes) per relation; 500 keyed fields per relation; 6,550 forms (windows); 55 significant digits in a number. The user's operating system or hardware may have more stringent limits than these

  4. Magnetic properties and specific heat of MPS3 (M=Mn, Fe, Zn)

    International Nuclear Information System (INIS)

    The magnetic properties and specific heat of MPS3 (M=Mn, Fe and Zn) have been investigated. While ZnPS3 is non-magnetic, MnPS3 and FePS3 are antiferromagnets with the Neel temperature TN of 78 and 118 K, respectively. Nevertheless, the specific heat of MnPS3 and FePS3 is smaller than that of ZnPS3 below about 20 K. The temperature dependence of the magnetic specific heat CM of MnPS3 shows a broad hump which is characteristic to the two dimensional magnetic materials and a small sharp peak at TN. On the other hand, that of FePS3 shows a large sharp peak at TN. As for FePS3, the temperature dependences of the magnetization M and CM are well reproduced by taking account of the magneto-elastic effect which introduces an additional term proportional to the square of the average value of the spin to the exchange coupling constant. As for MnPS3, marked two dimensional characters appear in the temperature dependence of M and CM. The observed TN is much smaller than the paramagnetic Curie temperature of 240 K obtained from the temperature dependence of the magnetic susceptibility at high temperature

    Development of NASA's Space Launch System (SLS) heavy lift rocket is shifting from the formulation phase into the implementation phase in 2014, a little more than three years after formal program approval. Current development is focused on delivering a vehicle capable of launching 70 metric tons (t) into low Earth orbit. This "Block 1" configuration will launch the Orion Multi-Purpose Crew Vehicle (MPCV) on its first autonomous flight beyond the Moon and back in December 2017, followed by its first crewed flight in 2021. SLS can evolve to a130-t lift capability and serve as a baseline for numerous robotic and human missions ranging from a Mars sample return to delivering the first astronauts to explore another planet. Benefits associated with its unprecedented mass and volume include reduced trip times and simplified payload design. Every SLS element achieved significant, tangible progress over the past year. Among the Program's many accomplishments are: manufacture of Core Stage test panels; testing of Solid Rocket Booster development hardware including thrust vector controls and avionics; planning for testing the RS-25 Core Stage engine; and more than 4,000 wind tunnel runs to refine vehicle configuration, trajectory, and guidance. The Program shipped its first flight hardware - the Multi-Purpose Crew Vehicle Stage Adapter (MSA) - to the United Launch Alliance for integration with the Delta IV heavy rocket that will launch an Orion test article in 2014 from NASA's Kennedy Space Center. Objectives of this Earth-orbit flight include validating the performance of Orion's heat shield and the MSA design, which will be manufactured again for SLS missions to deep space. The Program successfully completed Preliminary Design Review in 2013 and Key Decision Point C in early 2014. NASA has authorized the Program to move forward to Critical Design Review, scheduled for 2015 and a December 2017 first launch. The Program's success to date is due to prudent use of proven technology, infrastructure, and workforce from the Saturn and Space Shuttle programs, a streamlined management approach, and judicious use of new technologies. The result is a safe, affordable, sustainable, and evolutionary path to development of an unprecedented capability for future missions across the solar system. In an environment of economic challenges, the nationwide SLS team continues to meet ambitious budget and schedule targets. This paper will discuss SLS program and technical accomplishments over the past year and provide a look at the milestones and challenges ahead.

  6. Matrix-Product-State Algorithm for Finite Fractional Quantum Hall Systems

    2015-09-01

    Exact diagonalization is a powerful tool to study fractional quantum Hall (FQH) systems. However, its capability is limited by the exponentially increasing computational cost. In order to overcome this difficulty, density-matrix-renormalization-group (DMRG) algorithms were developed for much larger system sizes. Very recently, it was realized that some model FQH states have exact matrix-product-state (MPS) representation. Motivated by this, here we report a MPS code, which is closely related to, but different from traditional DMRG language, for finite FQH systems on the cylinder geometry. By representing the many-body Hamiltonian as a matrix-product-operator (MPO) and using single-site update and density matrix correction, we show that our code can efficiently search the ground state of various FQH systems. We also compare the performance of our code with traditional DMRG. The possible generalization of our code to infinite FQH systems and other physical systems is also discussed.

    Full Text Available Morquio A Syndrome (mucopolysaccharidosis IVA - MPS IVA, OMIM# 253000 is an autosomal recessive inborn error of metabolism caused by the deficiency of N-acetylgalactosamine-6-sulfate sulfatase (GALNS. We investigated five unrelated Brazilian MPS IVA families for mutations in exons 4, 5, 9 and 10 of the GALNS gene. Six out of the 10 mutant alleles were identified. Taken together with a previous study, which included six unrelated families, common mutations among Brazilian patients were p.N164T, p.G116S and p.G301C. Among one hundred control subjects three novel silent mutations were found (p.A107A; GCC -> GCT, p.Y108Y; TAC -> TAT, p.P357P; CCG -> CCA. Screening starting with exons 4, 5, 9, 10 and 11 may be a good strategy for genotyping of Brazilian patients since these exons include 73% of all mutations identified in the current and previous studies.

    The colloidal ZnS quantum dots (QDs) were prepared using 3-mercaptopropyltrimethoxysilane (MPS) molecules. Sol-gel spin coating method was used to deposit the colloidal nanoparticles on a glass substrate. Several features of the MPS were made use to produce self assembled thin films of ZnS quantum dots in a SiO2 network. Produced films were heat treated in between 225 °C and 325 °C to investigate their growth kinetics. The result showed that their size changed approximately from 3 nm to 4 nm and the first excitation peak position changed from 4.6 eV to 4.1 eV in this temperature interval. The activation energy of the nanoparticles for the Ostwald ripening process was found to be 59 kJ/mol.

    Mucopolysaccharidosis (MPS) is a group of lysosomal storage diseases (LSD), characterized by the deficiency of a lysosomal enzyme responsible for the degradation of glycosaminoglycans (GAG). This deficiency leads to the lysosomal accumulation of partially degraded GAG. Nevertheless, deficiency of a single lysosomal enzyme has been associated with impairment in other cell mechanism, such as apoptosis and redox balance. Although GAG analysis represents the main biomarker for MPS diagnosis, it has several limitations that can lead to a misdiagnosis, whereby the identification of new biomarkers represents an important issue for MPS. In this study, we used a system biology approach, through the use of a genome-scale human metabolic reconstruction to understand the effect of metabolism alterations in cell homeostasis and to identify potential new biomarkers in MPS. In-silico MPS models were generated by silencing of MPS-related enzymes, and were analyzed through a flux balance and variability analysis. We found that MPS models used approximately 2286 reactions to satisfy the objective function. Impaired reactions were mainly involved in cellular respiration, mitochondrial process, amino acid and lipid metabolism, and ion exchange. Metabolic changes were similar for MPS I and II, and MPS III A to C; while the remaining MPS showed unique metabolic profiles. Eight and thirteen potential high-confidence biomarkers were identified for MPS IVB and VII, respectively, which were associated with the secondary pathologic process of LSD. In vivo evaluation of predicted intermediate confidence biomarkers (?-hexosaminidase and ?-glucoronidase) for MPS IVA and VI correlated with the in-silico prediction. These results show the potential of a computational human metabolic reconstruction to understand the molecular mechanisms this group of diseases, which can be used to identify new biomarkers for MPS.

  10. Sensitivity study of melt behavior of Fukushima Daiichi unit 1 type accident with MELCOR code and MPS method

    International Nuclear Information System (INIS)

    Sensitivity calculation on melt behavior and lower head response at Fukushima Daiichi unit 1 reactor was performed with methods for estimation of leakages and consequences of releases (MELCOR) 2.1 and moving particle semi-implicit (MPS) method. Four sensitivity cases were calculated, considering safety relief valve (SRV) seizure, penetrations and debris porosity. The results indicated that the lower head failed due to creep rupture, not considering penetrations; otherwise it would have failed due to penetration tube rupture and ejection at an earlier time, resulting in part of debris dropping into the cavity of the drywell. The temperature of residual debris in pressure vessel kept low, and the vessel wall did not suffer creep failure up to 15 hours after reactor scram from which moment the water injection became available. Another aspect was that reactor pressure vessel (RPV) depressurization postponed the lower head creep failure time, and the low debris porosity brought forward the penetration rupture time. Either lower head creep failure or penetration rupture and ejection occurred in the central part of the pressure vessel. In MPS calculation, a slice of debris bed together with lower head, including an instrument guide tube, was chosen as the computational domian. Detailed temperature profiles in debris bed, penetration and vessel wall were obtained. The penetration rupture time calculated by MPS was earlier than the MELCOR result, while the vessel wall creep failure time was later. (author)

A full listing of the Conference, and how to obtain a copy of the proceedings, is shown on Page 300.The existing Loran-C and Chayka infrastructure can, with some minor changes, become a very powerful augmentation system for GNSS (GPS, GLONASS and the future Galileo). Delft University initially proposed the Eurofix concept in 1989. Although the necessary modification to the LF navigation systems are minimal, the GNSS user may get significant benefits from the Eurofix signals in terms of accuracy, integrity and availability. The reason is the high signal structure, signal propagation, and the operations dissimilarity of both systems. The broadcast correction and integrity data improves GNSS accuracy down to the metre level. In this way, the measured Loran-C and Chayka ranges are continuously updated. Thus, in the case of GNSS signal interruptions, highly calibrated Loran-C/Chayka may take over the navigation function. Tests carried out in Europe at the Loran-C station at Sylt (Germany) drew large international attention, leading to further tests in the USA by the US Coast Guard in 1998. Recently, a Dutch-Russian consortium implemented Eurofix on the Chayka transmitter at Bryansk (Russia) which is now successfully broadcasting DGPS as well as DGLONASS correction data. This paper highlights some on-air Eurofix DGPS performance experiments carried out in Europe and the USA. With all the European Loran-C and Chayka transmitters modified, Eurofix can be used all over the European continent. As multiple stations can normally be received simultaneously, the user may locally apply networked DGNSS, which may reduce spatial decorrelation effects significantly. Post-processed results of this Regional Area Augmentation System are presented.

  14. The Development of Surveillance Systems.

    Henderson, D A

    2016-03-01

    Surveillance systems in public health practice have increased in number and sophistication with advances in data collection, analysis, and communication. When the Communicable Disease Center (now the Centers for Disease Control and Prevention) was founded some 70 years ago, surveillance referred to the close observation of individuals with suspected smallpox, plague, or cholera. Alexander Langmuir, head of the Epidemiology Branch, redefined surveillance as the epidemiology-based critical factor in infectious disease control. I joined Langmuir as assistant chief in 1955 and was appointed chief of the Surveillance Section in 1961. In this paper, I describe Langmuir's redefinition of surveillance. Langmuir asserted that its proper use in public health meant the systematic reporting of infectious diseases, the analysis and epidemiologic interpretation of data, and both prompt and widespread dissemination of results. I outline the Communicable Disease Center's first surveillance systems for malaria, poliomyelitis, and influenza. I also discuss the role of surveillance in the global smallpox eradication program, emphasizing that the establishment of systematic reporting systems and prompt action based on results were critical factors of the program.

    International Nuclear Information System (INIS)

    The Transportation Technology Center at Sandia National Laboratories has taken the lead in the development of the TRansUranic PACkage Transporter I (TRUPACT-I) for transporting contact-handled transuranic waste. TRUPACT-I is a Type B package designed for transport by truck and rail. One of the regulatory requirements of a Type B package is that it survive a drop onto a 15.2-cm-dia punch. This paper discusses the development of the puncture resistant panels used in TRUPACT-I. Concepts tested ranged from monolithic steel plates to laminated Kevlar fabric bonded to a steel backing plate. The TRUPACT-I wall design incorporated the laminated Kevlar and stainless steel puncture panel

  18. Development of a diagnostic expert system for PWR feedwater system

    International Nuclear Information System (INIS)

    The feedwater system of a PWR plays an important role in normal plant operation and safety control under transient conditions and even a minor abnormality in this system may have a significant impact on the plant's operational integrity. So, the plant operator and maintenance staff must be knowledgeable about the feedwater system and the development of an expert system to support plant staff is desirable. A diagnostic expert system for PWR feedwater systems has been developed. As a first step, prototype system software for off-line diagnosis was developed. The essential functions of this system are to identify defective components and provide specific guidance for repair when an abnormality of the feedwater system occurs during plant operation. The paper presents a system configuration, methodology for diagnosis, results of test runs and evaluation for a prototype system. (author). Poster presentation. 1 ref., 3 figs

    The Workshops on Autonomous Systems emanated from a gathering with the doctoral students of just three chairs at Fernuniversität in Hagen, which we organise twice per year for a number of years now. Their purpose is to discuss on-going research and to create a community spirit. Furthermore, they serve as a means of structuring the students' research processes. The workshop has grown and matured in several respects. The doctoral students presenting their work do not come from a single university anymore, but from three. Besides them and their supervisors, also other scientists became interested in the event and contribute to its programme. Following the model of Advanced Study Institutes, they are available on the premises for relaxed, informal discussions outside the formal sessions. Finally, with the co-sponsorship of Gesellschaft für Informatik, the German Computer Society, and this surprisingly comprehensive volume of contributions published by Springer-Verlag the workshop turned into a visible scientifi...

    Full Text Available Objectives : Hand paresthesia is common syndrome and the cause is more unknown than known reason. The Purpose of this study were investigated the effects of Myofacial Pain Syndrome theory to make diagnosis and treatment by Pharmacopuncture for the patients of hand paresthesia. Method : This study was carried out to established the clinical criteria of hand parethesia. The patients who had past history of diabeics, neuropathy induced by alcohol or drug were excluded, and 86 patients who had hand paresthesia related with unknown-reason was selected by the interview process. And the effects of Pharmacopuncture theory were analyzed using VAS score before and after treatment. Results and conclusions : 56.9% of unknown-reason patients are positive at diagnosis by MPS theory. While positive group decrease from 62.81±14.27 to 25.28±15.97, negative group decrease from 55.88±10.92 to 48.28±14.01 by VAS scores. Positive group was accordingly more effective than negative group. So diagnosis and treatment for hand numbness patients by MPS theory was useful in clinical.

  5. Investigation of current transport parameters of Ti/4H-SiC MPS diode with inhomogeneous barrier

    International Nuclear Information System (INIS)

    The current transport parameters of 4H-SiC merged PiN Schottky (MPS) diode are investigated in a temperature range of 300–520 K. Evaluation of the experimental current–voltage (I—V) data reveals the decrease in Schottky barrier height ?b but an increase in ideality factor n, with temperature decreasing, which suggests the presence of an inhomogeneous Schottky barrier. The current transport behaviours are analysed in detail using the Tung's model and the effective area of the low barrier patches is extracted. It is found that small low barrier patches, making only 4.3% of the total contact, may significantly influence the device electrical characteristics due to the fact that a barrier height of 0.968 eV is much lower than the average barrier height 1.39 eV. This shows that ion implantation in the Schottky contact region of MPS structure may result in a poor Ti/4H-SiC interface quality. In addition, the temperature dependence of the specific on-resistance (Ron—sp), T2.14, is determined between 300 K and 520 K, which is similar to that predicted by a reduction in electron mobility.

  6. Elements of a successful safeguards system development

    International Nuclear Information System (INIS)

    The material control and accounting system in place in the nuclear fuel facility of the General Electric Wilmington Manufacturing Department has received national and international recognition as one of the best in the nuclear industry. Although only low enriched uranium is processed in the facility, the system has been identified as a model Material Control and Accounting tool capable of handling safeguards requirements applicable to high enriched uranium processing. The development of the system can also serve as a model for other systems, and this report is essentially a ''how to'' description of the GE experience. Important facets of the system development included actions taken to enhance input data accuracy, the diversity and depth in experience of the development team, the adequacy of the resources committed to development, and top management support of the project. Most provocative was the concept of the need for an integrated manufacturing information system rather than a safeguards system per se

    Full Text Available The paper describes a reference model of the national innovation system of Serbia planned to be gradually developed. The model presented is not complete, but is sufficient to illustrate its usage. The development of a national innovation system may be achieved by implementing a phased and segmented approach. This means that parts of the innovation system that are related to specific industrial sectors may be developed separately according to national priorities. Also, the system may be improved and expanded in later phases of its development. The approach suggested is demonstrated in the case of the innovation system of the software industry. The necessary programs and measures for supporting the development of the software industry are listed. Once these programs and measures are implemented, the software industry in Serbia may be able to reach global competitiveness.

    Walter, Maxwell; Karlsson, Sven

    2014-01-01

    Testing is an important part of system development, and to test effectively we require knowledge of the internal state of the system under test. Testing an operating system kernel is a challenge as it is the operating system that typically provides access to this internal state information. Multi-core kernels pose an even greater challenge due to concurrency and their shared kernel state. In this paper, we present a testing framework that addresses these challenges by running the operating system in a virtual machine, and using virtual machine introspection to both communicate with the kernel and obtain information about the system. We have also developed an in-kernel testing API that we can use to develop a suite of unit tests in the kernel. We are using our framework for for the development of our own multi-core research kernel.

  19. Doing learning : engineers in systems development

    DEFF Research Database (Denmark)

    Mathiasen, John Bang; Koch, Christian

    Purpose: To investigate how learning occurs in a systems development project, using a company developing wind turbine control systems in collaboration with customers as case. Design/methodology/approach: Dewey’s approach to learning is used, emphasising reciprocity between the individual’s experience and the sociotechnical practice. The framework involves the concepts of sociotechnical practice, anchoring of indeterminate situation, and strip of doings towards determinate situation. An ethnographic study was made of four cases of systems development. Findings: An extreme case reveals initiated learning processes and that the interchanges between materiality and systems developers block the learning processes due to a customer with imprecise demands and unclear system specifications. In the four cases discussed, learning does occur however. Research limitations/implications: A qualitative study focusing on individual systems developers gives limited insight into whether the learning processes found would occur in other systems development processes. Practical implications: Managers should ensure that constitutive means, such as specifications, are available, and that they are sufficiently obdurate. Too ductile means, such as customers with unclear demands, can block learning processes. Systems developers with different experience also enable learning processes. Converging anchoring of the indeterminate situation being handled enables collective learning. Focusing on this, systems development companies can safeguard their learning and product embedded knowledge when engaging in interorganisational collaboration handling the risk of giving knowledge away. Originality/value: The specific contribution involves Dewey’s approach to learning with focus on micro-processes of the individual systems developer’s learning, adding the possibility for collective learning.

    2015-01-01

    Drug discovery and development are hampered by high failure rates attributed to the reliance on non-human animal models employed during safety and efficacy testing. A fundamental problem in this inefficient process is that non-human animal models cannot adequately represent human biology. Thus, there is an urgent need for high-content in vitro systems that can better predict drug-induced toxicity. Systems that predict cardiotoxicity are of uppermost significance, as approximately one third of safety-based pharmaceutical withdrawals are due to cardiotoxicty. Here, we present a cardiac microphysiological system (MPS) with the attributes required for an ideal in vitro system to predict cardiotoxicity: i) cells with a human genetic background; ii) physiologically relevant tissue structure (e.g. aligned cells); iii) computationally predictable perfusion mimicking human vasculature; and, iv) multiple modes of analysis (e.g. biological, electrophysiological, and physiological). Our MPS is able to keep human induced pluripotent stem cell derived cardiac tissue viable and functional over multiple weeks. Pharmacological studies using the cardiac MPS show half maximal inhibitory/effective concentration values (IC50/EC50) that are more consistent with the data on tissue scale references compared to cellular scale studies. We anticipate the widespread adoption of MPSs for drug screening and disease modeling. PMID:25748532

    International Nuclear Information System (INIS)

    A critical enabling technology in the evolutionary development of nuclear thermal propulsion (NTP) is the ability to predict the system performance under a variety of operating conditions. Since October 1991, US (DOE), (DOD) and NASA have initiated critical technology development efforts for NTP systems to be used on Space Exploration Initiative (SEI) missions to the Moon and Mars. This paper presents the strategy and progress of an interagency NASA/DOE/DOD team for NTP system modeling. It is the intent of the interagency team to develop several levels of computer programs to simulate various NTP systems. An interagency team was formed for this task to use the best capabilities available and to assure appropriate peer review. The vision and strategy of the interagency team for developing NTP system models will be discussed in this paper. A review of the progress on the Level 1 interagency model is also presented

    This paper describes the studies, capabilities and challenges in initial development of a new digital encrypted termination system for space launch vehicles. This system is called the Space Launch Flight Termination System (SLFTS). Development of SLFTS is required to address an obsolescence issue and to improve the security of flight termination systems presently in use on the nation's space launch vehicles. SLFTS development was implemented in a four phase approach with the goal of producing a high secure, cost effective flight termination system for United Launch Alliance (ULA) and the United States Air Force (USAF) Evolved Expendable Launch Vehicle (EELV). These detailed study phases developed the requirements, design and implementation approach for a new high secure flight termination system. Studies led to a cost effective approach to replace the High Alphabet Command Receiver Decoders (HA-CRD) presently used on the EELV (Delta-IV & Atlas-V), with a common SLFTS unit. SLFTS is the next generation flight termination system for space launch vehicles, providing an assured high secure command destruct system for launch vehicles in flight. The unique capabilities and challenges to develop this technology for space launch use will be addressed in this paper in detail. This paper summarizes the current development status, design and capabilities of SLFTS for EELV.

    International Nuclear Information System (INIS)

    Construction of a large-scale helical device equipped with many measuring instruments is progressing in National Institute for Fusion Science. Aiming at the development of a control system using CAMAC, HIBP measuring system equipped with CHS experimental system was chosen as the object. It is necessary to operate all parts of the apparatus by remote-control. However, there are various functions necessary for the control system of those measuring equipments. Possibly, some of those functions such as those in the vacium-exhaust system can be controlled by a common system. The authors attempted to develop a control system composed of CAMAC controlled by an intelligent crate-controller, and a programmable logic one. In this report, this system, CAMAC and the latter controller are assigned to the real-time control of beam-orbital and the sequence control of the vacuum-exhaust apparatus, respectively. The real-time OS of the intelligent crate controller along with the above system is explained in this report. Further, development of an environment is which graphical user interface available for general-purpose net works is usable and also of a development of measuring control system with VME + VxWorks as well as CAMAC + VAXELN for comparison of the respective control systems are pointed out as the future problems.

    Hydrogen storage and delivery is an important element in effective hydrogen utilization for energy applications and is an important part of the FY1994-1998 Hydrogen Program Implementation Plan. This project is part of the Field Work Proposal entitled Hydrogen Utilization in Internal Combustion Engines (ICE). The goal of the Hydrogen Storage and Delivery System Development Project is to expand the state-of-the-art of hydrogen storage and delivery system design and development. At the foundation of this activity is the development of both analytical and experimental evaluation platforms. These tools provide the basis for an integrated approach for coupling hydrogen storage and delivery technology to the operating characteristics of potential hydrogen energy use applications. Analytical models have been developed for internal combustion engine (ICE) hybrid and fuel cell driven vehicles. The dependence of hydride storage system weight and energy use efficiency on engine brake efficiency and exhaust temperature for ICE hybrid vehicle applications is examined. Results show that while storage system weight decreases with increasing engine brake efficiency energy use efficiency remains relatively unchanged. The development, capability, and use of a newly developed fuel cell vehicle hydride storage system model will also be discussed. As an example of model use power distribution and control for a simulated driving cycle is presented. An experimental test facility, the Hydride Bed Testing Laboratory (HBTL) has been designed and fabricated. The development of this facility and its use in storage system development will be reviewed. These two capabilities (analytical and experimental) form the basis of an integrated approach to storage system design and development. The initial focus of these activities has been on hydride utilization for vehicular applications.

From the position of the functional approach, the structural unit of management activity is functional task management, the realization of which in the course of activities designed control technology. Functioning of many systems management processes and sub-processes is considered. A typical implementation of this act is to solve the set of specific management tasks to achieve the desired goal of a fixed initial situation. The contemporary development of organizations is determined by the necessity to respond to the current challenges and the market trends. In order to react adequately, it is important to use effective means to rebuild the systems of managing the economic systems referred to as organizations. We present a model of organization management system (OMS, and a model of development of organizational processes management system. We review the stages of the said models, including both the conceptual and the technological aspects of organization development based on reengineering. We emphasize the basic advantages of the described models. to reveal the main priorities of economic development of the region and to identify "hot spots", the industries that could be a source of risk and destabilize the economic regional security. Tver region is an example, as its main indicators of economic activity are on the average level of development. It gives the possibility of using tools to support the strategy of economic security at the regional level.

    2014-01-01

    In a world that increasingly relies on the Internet to function, application developers rely on the implementations of protocols to guarantee the security of data transferred. Whether a chosen protocol gives the required guarantees, and whether the implementation does the same, is usually unclear. The Guided System Development framework contributes to more secure communication systems by aiding the development of such systems. The framework features a simple modelling language, step-wise refinement from models to implementation, interfaces to security verification tools, and code generation from the verified specification. The refinement process carries thus security properties from the model to the implementation. Our approach also supports verification of systems previously developed and deployed. Internally, the reasoning in our framework is based on the Beliefs and Knowledge tool, a verification tool based on belief logics and explicit attacker knowledge.

    A critical enabling technology in the evolutionary development of nuclear thermal propulsion (NTP) is the ability to predict the system performance under a variety of operating conditions. This is crucial for mission analysis and for control subsystem testing as well as for the modeling of various failure modes. Performance must be accurately predicted during steady-state and transient operation, including startup, shutdown, and post operation cooling. The development and application of verified and validated system models has the potential to reduce the design, testing, and cost and time required for the technology to reach flight-ready status. Since Oct. 1991, the U.S. Department of Energy (DOE), Department of Defense (DOD), and NASA have initiated critical technology development efforts for NTP systems to be used on Space Exploration Initiative (SEI) missions to the Moon and Mars. This paper presents the strategy and progress of an interagency NASA/DOE/DOD team for NTP system modeling. It is the intent of the interagency team to develop several levels of computer programs to simulate various NTP systems. The first level will provide rapid, parameterized calculations of overall system performance. Succeeding computer programs will provide analysis of each component in sufficient detail to guide the design teams and experimental efforts. The computer programs will allow simulation of the entire system to allow prediction of the integrated performance. An interagency team was formed for this task to use the best capabilities available and to assure appropriate peer review.

  5. Proximity sensor system development. CRADA final report

    International Nuclear Information System (INIS)

    Lockheed Martin Energy Research Corporation (LMERC) and Merritt Systems, Inc. (MSI) entered into a Cooperative Research and Development Agreement (CRADA) for the development and demonstration of a compact, modular proximity sensing system suitable for application to a wide class of manipulator systems operated in support of environmental restoration and waste management activities. In teleoperated modes, proximity sensing provides the manipulator operator continuous information regarding the proximity of the manipulator to objects in the workspace. In teleoperated and robotic modes, proximity sensing provides added safety through the implementation of active whole arm collision avoidance capabilities. Oak Ridge National Laboratory (ORNL), managed by LMERC for the United States Department of Energy (DOE), has developed an application specific integrated circuit (ASIC) design for the electronics required to support a modular whole arm proximity sensing system based on the use of capacitive sensors developed at Sandia National Laboratories. The use of ASIC technology greatly reduces the size of the electronics required to support the selected sensor types allowing deployment of many small sensor nodes over a large area of the manipulator surface to provide maximum sensor coverage. The ASIC design also provides a communication interface to support sensor commands from and sensor data transmission to a distributed processing system which allows modular implementation and operation of the sensor system. MSI is a commercial small business specializing in proximity sensing systems based upon infrared and acoustic sensors

  10. Development of a refuelling support system

    International Nuclear Information System (INIS)

    In a refuelling operation, it is essential to handle fuel assemblies precisely so as to guarantee quality, and from the standpoint of safety. In order to plan and execute efficient operations, the knowledge of experienced operators is required. Therefore, a support system based on artificial intelligence (AI) technology has been developed, and has been put into operation in actual refuelling operations performed at annual inspection and on scheduled shutdown. This system prepares an optimum refuelling plan, gives the operator step-by-step instructions for operation, and displays and prints out the history of transfer and storage of items. A network uses AI to assist operators with fuel handling facilities and operational rules acquired through operating experience. The system was applied to the real control system in February 1995 and worked successfully. The development of this system has made it possible to optimize the refuelling schedule, reduce the operator's burden and improve the reliability of refuelling

    Ho, H.; Newell, J. F.

    1991-05-01

    A knowledge based system LDEXPT using the intelligent data base paradigm was developed for the Composite Load Spectra (CLS) project to simulate the probabilistic loads of a space propulsion system. The knowledge base approach provides a systematic framework of organizing the load information and facilitates the coupling of the numerical processing and symbolic (information) processing. It provides an incremental development environment for building generic probabilistic load models and book keeping the associated load information. A large volume of load data is stored in the data base and can be retrieved and updated by a built-in data base management system. The data base system standardizes the data storage and retrieval procedures. It helps maintain data integrity and avoid data redundancy. The intelligent data base paradigm provides ways to build expert system rules for shallow and deep reasoning and thus provides expert knowledge to help users to obtain the required probabilistic load spectra.

  12. Modified projective synchronization of a fractional-order hyperchaotic system with a single driving variable

    International Nuclear Information System (INIS)

    In this paper, the modified projective synchronization (MPS) of a fractional-order hyperchaotic system is investigated. We design the response system corresponding to the drive system on the basis of projective synchronization theory, and determine the sufficient condition for the synchronization of the drive system and the response system based on fractional-order stability theory. The MPS of a fractional-order hyperchaotic system is achieved by transmitting a single variable. This scheme reduces the information transmission in order to achieve the synchronization, and extends the applicable scope of MPS. Numerical simulations further demonstrate the feasibility and the effectiveness of the proposed scheme. (general)

    Hydrogen storage and delivery is an important element in effective hydrogen utilization for energy applications and is an important part of the FY1994-1998 Hydrogen Program Implementation Plan. The purpose of this project is to develop a platform for the engineering evaluation of hydrogen storage and delivery systems with an added focus on lightweight hydride utilization. Hybrid vehicles represent the primary application area of interest, with secondary interests including such items as existing vehicles and stationary uses. The near term goal is the demonstration of an internal combustion engine/storage/delivery subsystem. The long term goal is optimization of storage technologies for both vehicular and industrial stationary uses. In this project an integrated approach is being used to couple system operating characteristics to hardware development. A model has been developed which integrates engine and storage material characteristics into the design of hydride storage and delivery systems. By specifying engine operating parameters, as well as a variety of storage/delivery design features, hydride bed sizing calculations are completed. The model allows engineering trade-off studies to be completed on various hydride material/delivery system configurations. A more generalized model is also being developed to allow the performance characteristics of various hydrogen storage and delivery systems to be compared (liquid, activated carbon, etc.). Many of the features of the hydride storage model are applicable to the development of this more generalized model.

Background information on the OCRWM transportation cask systems development activities and the relevant industry activities will also be provided

  15. An INTEL 8080 microprocessor development system

    International Nuclear Information System (INIS)

    The INTEL 8080 has become one of the two most widely used microprocessors at CERN, the other being the MOTOROLA 6800. Even thouth this is the case, there have been, to date, only rudimentary facilities available for aiding the development of application programs for this microprocessor. An ideal development system is one which has a sophisticated editing and filing system, an assembler/compiler, and access to the microprocessor application. In many instances access to a PROM programmer is also required, as the application may utilize only PROMs for program storage. With these thoughts in mind, an INTEL 8080 microprocessor development system was implemented in the Proton Synchrotron (PS) Division. This system utilizes a PDP 11/45 as the editing and file-handling machine, and an MSC 8/MOD 80 microcomputer for assembling, PROM programming and debugging user programs at run time. The two machines are linked by an existing CAMAC crate system which will also provide the means of access to microprocessor applications in CAMAC and the interface of the development system to any other application.

    Lusby, Brian S.; Miranda, Bruno M.; Collins, Jacob A.

    2011-01-01

    The Propulsion Systems Branch at NASA s Lyndon B. Johnson Space Center (JSC) has developed a parametric analytical tool to address the need to rapidly predict heat leak into propellant distribution lines based on insulation type, installation technique, line supports, penetrations, and instrumentation. The Propellant Feed System Analytical Tool (PFSAT) will also determine the optimum orifice diameter for an optional thermodynamic vent system (TVS) to counteract heat leak into the feed line and ensure temperature constraints at the end of the feed line are met. PFSAT was developed primarily using Fortran 90 code because of its number crunching power and the capability to directly access real fluid property subroutines in the Reference Fluid Thermodynamic and Transport Properties (REFPROP) Database developed by NIST. A Microsoft Excel front end user interface was implemented to provide convenient portability of PFSAT among a wide variety of potential users and its ability to utilize a user-friendly graphical user interface (GUI) developed in Visual Basic for Applications (VBA). The focus of PFSAT is on-orbit reaction control systems and orbital maneuvering systems, but it may be used to predict heat leak into ground-based transfer lines as well. PFSAT is expected to be used for rapid initial design of cryogenic propellant distribution lines and thermodynamic vent systems. Once validated, PFSAT will support concept trades for a variety of cryogenic fluid transfer systems on spacecraft, including planetary landers, transfer vehicles, and propellant depots, as well as surface-based transfer systems. The details of the development of PFSAT, its user interface, and the program structure will be presented.

  19. Development of the Hypothalamic Melanocortin System

    Directory of Open Access Journals (Sweden)

    SebastienGBouret

    2013-03-01

    Full Text Available The melanocortin system is a critical component of the forebrain and hindbrain regulatory systems involved in energy balance. This system is composed of pro-opiomelanocortin (POMC neurons that act, in part, through the melanocortin-4 receptor (MC4R. Although the importance of the melanocortin system in controlling feeding has been established for two decades, the understanding of the developmental substrates underlying POMC and MC4R neuron development and function has just begun to emerge. The formation of the melanocortin system involves several discrete developmental steps that include the birth and fate specification of POMC- and MC4R-containing neurons and the extension and guidance of POMC axons to their MC4R-expressing target nuclei. Each of these developmental processes appears to require specific sets of genes and developmental cues that include perinatal hormones. Recent evidence has also highlighted the importance of perinatal nutrition in controlling the ultimate architecture of the melanocortin system.

The system has promoted higher design quality and greatly reduced design cost. (author)

  3. Development of industrial variant specification systems

    DEFF Research Database (Denmark)

    Hansen, Benjamin Loer

    2003-01-01

    With globalisation and increased competition industrial companies must be prepared to satisfy individual customer needs and still stay competitive with regards to lead times, quality, and prices. These factors require companies to be better prepared to handle specification activities during order acquisition and order fulfilment, i.e. the creation of drawings, bill-of-materials, routings, product descriptions, quote letters etc. The present thesis is rooted in the assumption that variant specification systems supporting the cross-functional processes of order acquisition and order fulfilment must be developed from a holistic and strategically anchored point of view. Another assumption is that this is a challenge for many industrial companies. Even though the literature presents many considerations on general issues covering new information technology, little work is found on the business perspectives and the challenge of understanding the variant specification tasks and the connections between variant specification, product development, sales, manufacturing, and information technology. The present thesis seeks to meet this challenge with a procedure, concepts and tools. This is done through an extensive answer to the four research tasks of the Ph.D. project: • Define and describe the variant specification system. • Create a procedure for the development of variant specification systems. • Create concepts, methods and tools to support the analysis and determination of the variant specification task. • Identify solution elements and structural variables to be used in the design of variant specification systems. The thesis presents a “top-down” procedure to be used to develop variant specification systems from a strategically anchored and holistic point of view. A methodology and related task variables are presented for analysing and determining the variant specification task. These are grouped in external and internal task variables. Additionally functional characteristics, which can be used for defining performance measures, are defined. Based in the concept of “focus” different levels of tasks are discussed. A list of structural variables and solution components has been created. These are related to four design aspects in the holistic system design covering the aspects of process design, selection of resources (such as hardware, software and humans), the design of information structures, and the design of organisational structures. The elements in the thesis have been created and evaluated through two case studies. Action research has been conducted in combination with the design and implementation of IT based variant specification systems. One of the case companies has successfully implemented highly advanced variant specification systems. In this company, the subject has been given a high strategic priority, and many new developers have been assigned to continue the development of such systems. In conclusion, the thesis presents a valuable platform for researchers and practitioners doing projects related to the development of variant specification systems.

    The mission of the United States Department of Energy's Office of Environmental Management is to complete the safe cleanup of the environmental legacy brought about from five decades of nuclear weapons development and go vernment - sponsored nuclear energy re search. S ome of the waste s that that must be managed have be en identified as good candidates for disposal in a deep borehole in crystalline rock (SNL 2014 a). In particular, wastes that can be disposed of in a small package are good candidates for this disposal concept. A canister - based system that can be used for handling these wastes during the disposition process (i.e., storage, transfers, transportation, and disposal) could facilitate the eventual disposal of these wastes. This report provides information for a program plan for developing specifications regarding a canister - based system that facilitates small waste form packaging and disposal and that is integrated with the overall efforts of the DOE's Office of Nuclear Energy Used Fuel Dis position Camp aign's Deep Borehole Field Test . Groundwork for Universal Ca nister System Development September 2015 ii W astes to be considered as candidates for the universal canister system include capsules containing cesium and strontium currently stored in pools at the Hanford Site, cesium to be processed using elutable or nonelutable resins at the Hanford Site, and calcine waste from Idaho National Laboratory. The initial emphasis will be on disposal of the cesium and strontium capsules in a deep borehole that has been drilled into crystalline rock. Specifications for a universal canister system are derived from operational, performance, and regulatory requirements for storage, transfers, transportation, and disposal of radioactive waste. Agreements between the Department of Energy and the States of Washington and Idaho, as well as the Deep Borehole Field Test plan provide schedule requirements for development of the universal canister system . Future work includes collaboration with the Hanford Site to move the cesium and strontium capsules into dry storage, collaboration with the Deep Borehole Field Tes t to develop surface handling and emplacement techniques and to develop the waste package design requirements, developing universal canister system design options and concepts of operations, and developing system analysis tools. Areas in which f urther research and development are needed include material properties and structural integrity, in - package sorbents and fillers, waste form tolerance to heat and postweld stress relief, waste package impact limiters, sensors, cesium mobility under downhol e conditions, and the impact of high pressure and high temperature environment on seals design.

  5. A Systems Engineering Approach to Architecture Development

    Science.gov (United States)

    Di Pietro, David A.

    2015-01-01

    Architecture development is often conducted prior to system concept design when there is a need to determine the best-value mix of systems that works collectively in specific scenarios and time frames to accomplish a set of mission area objectives. While multiple architecture frameworks exist, they often require use of unique taxonomies and data structures. In contrast, this paper characterizes architecture development using terminology widely understood within the systems engineering community. Using a notional civil space architecture example, it employs a multi-tier framework to describe the enterprise level architecture and illustrates how results of lower tier, mission area architectures integrate into the enterprise architecture. It also presents practices for conducting effective mission area architecture studies, including establishing the trade space, developing functions and metrics, evaluating the ability of potential design solutions to meet the required functions, and expediting study execution through the use of iterative design cycles.

One product of this project has been the Thermal Performance Diagnostic Manual for Nuclear Power Plants (NP-4990P). The purpose of this manual is to provide engineering personnel at nuclear power plants with a consistent way in which to identify thermal performance problems. General Physics is also involved in the development of another computer system called Fossil Thermal Performance Advisor (FTPA) which helps operators improve performance for fossil power plants. FTPA is a joint venture between General Physics and New York State Electric and Gas Company. This paper describes both of these computer systems and uses the FTPA as an interesting comparison that illustrates the considerations required for the development of a computer system that effectively addresses the needs of the users

  7. A Systems Engineering Approach to Architecture Development

    Di Pietro, David A.

    2015-01-01

    Architecture development is often conducted prior to system concept design when there is a need to determine the best-value mix of systems that works collectively in specific scenarios and time frames to accomplish a set of mission area objectives. While multiple architecture frameworks exist, they often require use of unique taxonomies and data structures. In contrast, this paper characterizes architecture development using terminology widely understood within the systems engineering community. Using a notional civil space architecture example, it employs a multi-tier framework to describe the enterprise level architecture and illustrates how results of lower tier, mission area architectures integrate into the enterprise architecture. It also presents practices for conducting effective mission area architecture studies, including establishing the trade space, developing functions and metrics, evaluating the ability of potential design solutions to meet the required functions, and expediting study execution through the use of iterative design cycles

    The application of new technologies to the control and automation of irrigation processes is quickly gaining attention. The automation of irrigation execution (through irrigation controllers) is now widespread. However, the automatic generation and execution of irrigation schedules is receiving growing attention due to the possibilities offered by the telemetry/remote control systems currently being installed in collective pressurized networks. These developments can greatly benefit from the combination of irrigation system and crop models, and from the interaction with agrometeorological databases, hydraulic models of pressurized collective distribution networks, weather forecasts and management databases for water users associations. Prospects for the development of such systems in collective sprinkler irrigation systems are analyzed in this presentation. Additionally, experimental results are presented on the application of these concepts to a hydrant irrigating a solid-set irrigated maize field.

A High Consequence System is a system whose failure could lead to serious injury, loss of life, destruction of valuable resources, unauthorized use, damaged reputation or loss of credibility or compromise of protected information. This methodology can be scaled for use in projects of any size and complexity and does not prescribe any specific software engineering technology. Tasks are described that ensure software is developed in a controlled environment. The effort needed to complete the tasks will vary according to the size, complexity, and risks of the project. The emphasis of this methodology is on obtaining the desired attributes for each individual High Consequence System.

  12. Reactor alarm system development and application issues

    International Nuclear Information System (INIS)

    The new hardware and software technologies, and the need in research reactors for assistance systems in operation and maintenance, have given an appropriate background to develop a computer based system named ''Reactor Alarm System'' (RAS). RAS is a software package, user oriented, with emphasis on production, experiments and maintenance goals. It is designed to run on distributed systems conformed with microcomputers under QNX operating system. RAS main features are: a) Alarm Panel Display; b) Alarm Page; c) Alarm Masking and Inhibition; d) Alarms Color and Attributes; e) Condition Classification; and f) Arrangement Presentation. RAS design allows it to be installed as a part of a computer based Supervision and Control System in new installations or retrofit existing reactor instrumentation systems. The analysis of human factors during development stage and successive user feedback from different applications, brought out several RAS improvements: a) Multiple-copy alarm summaries; b) Improved alarm handling; c) Extended dictionary; and d) Enhanced hardware availability. It has proved successful in providing new capabilities for operators, and also has shown the continuous increase of user-demands, reflecting the expectations placed today on computer-based systems.

Particular attention is given to the management of system development when there is uncertainty. System dynamics, flexibility, adaptability and reliability are some of the properties studied. It is shown why guaranteed strategies are preferable for securing maximum reliability of energy systems development and most efficient distribution among energy industries of the limited resources of the national economy. In the second paper the system for centralized management of energy development in the USSR and planned methods of improvement by increasing the economic independence of power plants and making economic control links more effective are analyzed. The degree and organization of control over energy development are considered as an organized hierarchical process. The system of work (make-up, sequence and content) for controlling energy development currently in existence in the USSR is discussed. (orig.).

    1996-10-01

    Hydrogen storage and delivery is an important element in effective hydrogen utilization for energy applications and is an important part of the FY1994-1998 Hydrogen Program Implementation Plan. This project is part of the Field Work Proposal entitled Hydrogen Utilization in Internal Combustion Engines (ICE). The goal of the Hydrogen Storage and Delivery System Development Project is to expand the state-of-the-art of hydrogen storage and delivery system design and development. At the foundation of this activity is the development of both analytical and experimental evaluation platforms. These tools provide the basis for an integrated approach for coupling hydrogen storage and delivery technology to the operating characteristics of potential hydrogen energy use applications. Results of the analytical model development portion of this project will be discussed. Analytical models have been developed for internal combustion engine (ICE) hybrid and fuel cell driven vehicles. The dependence of hydride storage system weight and energy use efficiency on engine brake efficiency and exhaust temperature for ICE hybrid vehicle applications is examined. Results show that while storage system weight decreases with increasing engine brake efficiency energy use efficiency remains relatively unchanged. The development, capability, and use of a recently developed fuel cell vehicle storage system model will also be discussed. As an example of model use, power distribution and control for a simulated driving cycle is presented. Model calibration results of fuel cell fluid inlet and exit temperatures at various fuel cell idle speeds, assumed fuel cell heat capacities, and ambient temperatures are presented. The model predicts general increases in temperature with fuel cell power and differences between inlet and exit temperatures, but under predicts absolute temperature values, especially at higher power levels.

    2002-02-01

    Using recent technologies on a mobile robot computer science, we developed an automatic inspection system for weld lines of the reactor vessel. The ultrasonic inspection of the reactor pressure vessel is currently performed by commercialized robot manipulators. Since, however, the conventional fixed type robot manipulator is very huge, heavy and expensive, it needs long inspection time and is hard to handle and maintain. In order to resolve these problems, we developed a new automatic inspection system using a small mobile robot crawling on the vertical wall of the reactor vessel. According to our conceptual design, we developed the reactor inspection system including an underwater inspection robot, a laser position control subsystem, an ultrasonic data acquisition/analysis subsystem and a main control subsystem. We successfully carried out underwater experiments on the reactor vessel mockup, and real reactor ready for Ulchine nuclear power plant unit 6 at Dusan Heavy Industry in Korea. After this project, we have a plan to commercialize our inspection system. Using this system, we can expect much reduction of the inspection time, performance enhancement, automatic management of inspection history, etc. In the economic point of view, we can also expect import substitution more than 4 million dollars. The established essential technologies for intelligent control and automation are expected to be synthetically applied to the automation of similar systems in nuclear power plants.

  4. Development of an omnidirectional vision system

    Valdir, Grassi Junior; Jun, Okamoto Junior.

    2006-03-01

    Full Text Available Omnidirectional vision systems can provide images with a 360° of field of view. For this reason, they can be useful to robotic applications such as navigation, teleoperation and visual servoing. An effective way to construct this type of vision system is by combining lenses and mirrors together resu [...] lting on a system that does not require the movement of the camera to the direction of attention of the robot. A typical construction is by mounting a convex mirror in front of a camera aligning the center of the mirror with the optical axis of the camera. The most common convex mirror shapes used are conic, parabolic, hyperbolic and spherical. In this work we present two types of mirror that were constructed: a spherical mirror, used in the initial tests, and a hyperbolic, used for actual robot tasks. The hyperbolic mirror was manufactured using an ultra-precision CNC machine. Additionally, a software was developed to create panoramic and perspective images from the image acquired by the system. This work shows the development of an omnidirectional vision system, presenting the formulation used to determine a suitable mirror shape, the mechanical solutions used to build a fully operational system, and the results of the developed algorithm.

    Paul, Ben E.; Cobbett, John A.

    A Laser Ordnance Initiation System (LOIS) has been developed for use in military aircraft emergency escape/egress systems. Applying LOIS to a single-seat and a two-seat F-16 aircraft escape system has proven both cost and weight effective. In both cases, system redundancy is supplied. The large weight reduction is attributed to the elimination of certain initiators, the small size of the logic components and the low weight of the fiber-optic lines (0.037 lb/ft). The required components for a laser operated escape systems are described, with emphasis on the mechanically actuated pyrolaser, which supplies the required energy to activate the various seat devices; the optical AND gate, which provides the logic to ensure proper event sequencing; and the optical mode selector, which establishes aircrew control of the ejection sequence in multiseat aircraft only.

Initial testing and familiarization of the currently obtained prototype components is underway, however full prototype construction is required for further optimization. Monte Carlo models of the prototype system were performed to estimate die-away and efficiency values. Analysis of these models resulted in the development of a software package capable of determining the effects of nearest-neighbor rejection methods for elimination of detector cross talk. A parameter study was performed using previously developed analytical methods for the estimation of assay mass variance for use as a figure-of-merit for system performance. A software package was developed to automate these calculations and ensure accuracy. The results of the parameter study show that the prototype fast neutron multiplicity counter design is very nearly optimized under the restraints of the parameter space.

    Over the past few decades, considerable attention has been given to structural control systems to mitigate structural vibration under natural hazards such as earthquakes and extreme weather conditions. Traditional wired structural control systems often employ a large amount of cables for communication among sensors, controllers and actuators. In such systems, implementation of wired sensors is usually quite complicated and expensive, especially on large scale structures such as bridges and buildings. To reduce the laborious installation and maintenance cost, wireless control systems (WCSs) are considered as a novel approach for structural vibration control. In this work, a WCS is developed based on the open source Arduino platform. Low cost, low power wireless sensing and communication components are built on the Arduino platform. Structural control algorithms are embedded within the wireless sensor board for feedback control. The developed WCS is first validated through a series of tests. Next, numerical simulations are performed simulating wireless control of a 3-story shear structure equipped with a semi-active control device (MR damper). Finally, experimental studies are carried out implementing the WCS on the 3-story shear structure in the Intelligent Infrastructure Systems Lab (IISL). A hydraulic shake table is used to generate seismic ground motions. The control performance is evaluated with the impact of modeling uncertainties, measurement noises as well as time delay and data loss induced by the wireless network. The developed WCS is shown to be effective in controlling structural vibrations under several historical earthquake ground motions.

  13. Development of an advanced robot manipulator system

    International Nuclear Information System (INIS)

    A sophisticated manipulator system for an advanced robot was developed under the 'Advanced Robot Technology Development' Program promoted and supported by the Agency of Industrial Science and Technology of MITI. The authors have participated in the development of a fingered manipulator with force and tactile sensors applicable to a masterslave robot system. Our slave manipulator is equipped with four fingers. Though the finger needs many degrees of freedom so as to be suitable for skilful handing of an object, our fingers are designed to have minimum degree of freedom in order to reduce weight. Each finger tip was designed to be similar to a human finger which has flexibility, softness and contact feeling. The shape of the master finger manipulator was so designed that the movement of the fingers is smoother and that the constraint feeling of the operator is smaller. We were adopted to a pneumatic pressure system for transmitting the tactile feeling of the slave fingers to the master fingers. A multiple sensory bilateral control system which gives an operator a feeling of force and tactile reduces his feeling of constraint in carrying out work with a robot system. (author)

  14. Advanced CIDI Emission Control System Development

    Lambert, Christine

    2006-05-31

    Ford Motor Company, with ExxonMobil and FEV, participated in the Department of Energy's (DOE) Ultra-Clean Transportation Fuels Program with the goal to develop an innovative emission control system for light-duty diesel vehicles. The focus on diesel engine emissions was a direct result of the improved volumetric fuel economy (up to 50%) and lower CO2 emissions (up to 25%) over comparable gasoline engines shown in Europe. Selective Catalytic Reduction (SCR) with aqueous urea as the NOx reductant and a Catalyzed Diesel Particulate Filter (CDPF) were chosen as the primary emission control system components. The program expected to demonstrate more than 90% durable reduction in particulate matter (PM) and NOx emissions on a light-duty truck application, based on the FTP-75 drive cycle. Very low sulfur diesel fuel (<15 ppm-wt) enabled lower PM emissions, reduced fuel economy penalty due to the emission control system and improved long-term system durability. Significant progress was made toward a durable system to meet Tier 2 Bin 5 emission standards on a 6000 lbs light-duty truck. A 40% reduction in engine-out NOx emissions was achieved with a mid-size prototype diesel engine through engine recalibration and increased exhaust gas recirculation. Use of a rapid warm-up strategy and urea SCR provided over 90% further NOx reduction while the CDPF reduced tailpipe PM to gasoline vehicle levels. Development work was conducted to separately improve urea SCR and CDPF system durability, as well as improved oxidation catalyst function. Exhaust gas NOx and ammonia sensors were also developed further. While the final emission control system did not meet Tier 2 Bin 5 NOx after 120k mi of aging on the dynamometer, it did meet the standards for HC, NMOG, and PM, and an improved SCR catalyst was shown to have potential to meet the NOx standard, assuming the DOC durability could be improved further. Models of DOC and SCR function were developed to guide the study of several key design factors for SCR systems and aid in the development of urea control strategy for maximum NOx reduction with minimum NH3 slip. A durable co-fueling system was successfully built and tested, with the help of service station nozzle and dispenser manufacturers, for simultaneous delivery of diesel fuel and aqueous urea to the vehicle. The business case for an aqueous urea infrastructure in the US for light-duty vehicles was explored.

  2. Towards a Provotyping Approach in Systems Development

    DEFF Research Database (Denmark)

    Mogensen, Preben Holst

    1992-01-01

    This paper explores the notion of ‘provocation through concrete experience’ towards a provotyping approach. It addresses the question: How do we on the one hand, devise qualitatively new systems, and on the other hand, ensure their usability in a given practice? The notion of provocation through concrete experience is developed through an investigation of prototyping and activity theory. Exploration of this notion leads to the idea of the systemdeveloper ‘provoking ’ concrete, everyday practice, by exposing current problems, calling forth what usually is taken for granted. Problems with current practice and a lack of mutual understanding, usually conceived of as hindrances to successful systems development, are used constructively. These ideas are compared to four related approaches: Future Workshops, Metaphorical Design, Cooperative Prototyping, and Organizational Games. The comparison serves the twofold purpose of contextualizing the new ideas as well as developing techniques for carrying themout.

  4. Development of computerized event sequence abstracting system

    International Nuclear Information System (INIS)

    For the purpose of efficient utilization of safety-related event information on nuclear power plants, a new computer software package CESAS has been developed. CESAS is to extract systematically the event sequence, that is sequential and causal relationship between occurrences, from the event description written in natural language of English. This system is designed to be based on knowledge engineering technique utilized in the field of natural language treatment. The analytical process in this system consists of following three steps: (1) To analyze each sentence syntactically and semantically (2) To identify sentences, clauses or phrases representing occurrences (3) To deduce the mutual relationship between occurrences. An existing syntactic analysis approach is applied to the above (1) step. As for (2) and (3) steps, a new analytical approach has been developed. In this paper, the outlines of CESAS and the newly developed approach are described and the analytical result is shown in comparison with a manually-extracted event sequence. (author)

  7. Development of compact CCTV surveillance system. 'COSMOS'

    International Nuclear Information System (INIS)

    The Compact Surveillance and Monitoring System, 'COSMOS' has been developed as a compact, simple, highly reliable CCTV surveillance system. The system is intended to provide a direct replacement for the IAEA Twin Minolta film camera systems. The system consists of a recording unit and a set up/review unit. The recording unit, consisting of a CCD camera module, a 8mm VTR unit, a controller module and a power unit, is contained in a tamper indicating housing. The VTR module of very low power consumption is specially developed for COSMOS capable of battery operation. The system can be operated for three months either by battery without battery change where mains power is not readily available or by AC powers. The field-use model of COSMOS was completed in 1991. The field-evaluation test by the IAEA and JAERI was successfully completed in 1993. The IAEA accepted the COSMOS as a routine-use device in August 1993. This report describes the performance features and IAEA test result of COSMOS. (author)

  8. Development of an Integrated Distribution Management System

    Schatz, Joe E.

    2010-10-20

    This final report details the components, functionality, costs, schedule and benefits of developing an Integrated Distribution Management System (IDMS) for power distribution system operation. The Distribution Automation (DA) and Supervisory Control and Data Acquisition (SCADA) systems used by electric power companies to manage the distribution of electric power to retail energy consumers are vital components of the Nation’s critical infrastructure. Providing electricity is an essential public service and a disruption in that service, if not quickly restored, could threaten the public safety and the Nation’s economic security. Our Nation’s economic prosperity and quality of life have long depended on the essential services that utilities provide; therefore, it is necessary to ensure that electric utilities are able to conduct their operations safely and efficiently. A fully integrated technology of applications is needed to link various remote sensing, communications and control devices with other information tools that help guide Power Distribution Operations personnel. A fully implemented IDMS will provide this, a seamlessly integrated set of applications to raise electric system operating intelligence. IDMS will enhance DA and SCADA through integration of applications such as Geographic Information Systems, Outage Management Systems, Switching Management and Analysis, Operator Training Simulator, and other Advanced Applications, including unbalanced load flow and fault isolation/service restoration. These apps are capable of utilizing and obtaining information from appropriately installed DER, and by integrating disparate systems, the Distribution Operators will benefit from advanced capabilities when analyzing, controlling and operating the electric system.

  9. Development of a Universal Waste Management System

    Science.gov (United States)

    Stapleton, Thomas J.; Baccus, Shelley; Broyan, James L., Jr.

    2013-01-01

    NASA is working with a number of commercial companies to develop the next low Earth orbit spacecraft. The hardware volume and weight constraints are similar to or greater than those of the Apollo era. This, coupled with the equally demanding cost challenge of the proposed commercial vehicles, causes much of the Environmental Control and Life Support System (ECLSS) designs to be reconsidered. The Waste Collection System (WCS) is within this group of ECLSS hardware. The development to support this new initiative is discussed within. A WCS concept - intended to be common for all the vehicle platforms currently on the drawing board - is being developed. The new concept, referred to as the Universal Waste Management System (UWMS), includes favorable features from previous designs while improving on other areas on previous Space Shuttle and the existing International Space Station (ISS) WCS hardware, as needed. The intent is to build a commode that requires less crew time, improved cleanliness, and a 75% reduction in volume and weight compared to the previous US ISS/Extended Duration Orbitor WCS developed in the 1990s. The UWMS is most similar to the ISS Development Test Objective (DTO) WCS design. It is understood that the most dramatic cost reduction opportunity occurs at the beginning of the design process. To realize this opportunity, the cost of each similar component between the UWMS and the DTO WCS was determined. The comparison outlined were the design changes that would result with the greatest impact. The changes resulted in simplifying the approach or eliminating components completely. This initial UWMS paper will describe the system layout approach and a few key features of major components. Future papers will describe the UWMS functionality, test results, and components as they are developed.

  10. J-2X Abort System Development

    Science.gov (United States)

    Santi, Louis M.; Butas, John P.; Aguilar, Robert B.; Sowers, Thomas S.

    2008-01-01

    The J-2X is an expendable liquid hydrogen (LH2)/liquid oxygen (LOX) gas generator cycle rocket engine that is currently being designed as the primary upper stage propulsion element for the new NASA Ares vehicle family. The J-2X engine will contain abort logic that functions as an integral component of the Ares vehicle abort system. This system is responsible for detecting and responding to conditions indicative of impending Loss of Mission (LOM), Loss of Vehicle (LOV), and/or catastrophic Loss of Crew (LOC) failure events. As an earth orbit ascent phase engine, the J-2X is a high power density propulsion element with non-negligible risk of fast propagation rate failures that can quickly lead to LOM, LOV, and/or LOC events. Aggressive reliability requirements for manned Ares missions and the risk of fast propagating J-2X failures dictate the need for on-engine abort condition monitoring and autonomous response capability as well as traditional abort agents such as the vehicle computer, flight crew, and ground control not located on the engine. This paper describes the baseline J-2X abort subsystem concept of operations, as well as the development process for this subsystem. A strategy that leverages heritage system experience and responds to an evolving engine design as well as J-2X specific test data to support abort system development is described. The utilization of performance and failure simulation models to support abort system sensor selection, failure detectability and discrimination studies, decision threshold definition, and abort system performance verification and validation is outlined. The basis for abort false positive and false negative performance constraints is described. Development challenges associated with information shortfalls in the design cycle, abort condition coverage and response assessment, engine-vehicle interface definition, and abort system performance verification and validation are also discussed.

    Attention is given to the development of a laboratory model of an airborne computer associated with a strapdown gyro unit manufactured by an U.S. aerospace company. The considered system should satisfy the requirements for a small satellite launcher. The inertial unit includes two dry tuned-rotor gyros and two-scale digitizers. The computing system includes a 8087 numeric coprocessor and an 8086 16-bit processor. The 8087 implements with high speed and precision floating-point operations including trigonometric functions. The algorithm for the computer is discussed, taking into account the use of the quaternion method for obtaining attitude information. In an evaluation of the merits of the selected computing system it is pointed out that the availability of low cost high performance numeric processors gives the sounding rocket community the possibility of using a powerful airborne computer of standard design, with enough capability to implement a strapdown inertial reference system.

  17. Oral health care systems in developing and developed countries

    DEFF Research Database (Denmark)

    Kandelman, Daniel; Arpin, Sophie

    2012-01-01

    Health care systems are essential for promoting, improving and maintaining health of the population. Through an efficient health service, patients can be advised of disease that may be present and so facilitate treatment; risks factors whose modification could reduce the incidence of disease and illness in the future can be identified, and further, how controlling such factors can contribute to maintain a good quality of life. In developed countries, clinics or hospitals may be supported by health professionals from various specialties that allow their cooperation to benefit the patient; these institutions or clinics may be equipped with the latest technical facilities. In developing countries, health services are mostly directed to provide emergency care only or interventions towards certain age group population. The most common diseases are dental caries and periodontal disease and frequently intervention procedures aim, at treating existing problems and restore teeth and related structure to normal function. It is unfortunate that the low priority given to oral health hinders acquisition of data and establishment of effective periodontal care programmes in developing countries but also in some developed countries where the periodontal profile is also less than satisfactory. Despite the fact that in several developed countries there are advanced programmes oriented to periodontal disease treatments, the concern is related to the lack of preventive oriented treatments. According to data available on periodontal status of populations from developed countries, despite the number of dentists and trained specialists, dental health professionals do not presently meet adequately the need for prevention, focusing mainly on curative care. The need for strengthening disease prevention and health promotion programmes in order to improve oral health conditions and particularly periodontal status in the majority of countries around the world is evident. Unfortunately, in many countries, the human, financial and material resources are still insufficient to meet the need for oral health care services and to provide universal access, especially in disadvantaged communities, in both developing and developed countries. Moreover, even though the most widespread illnesses are avoidable, not all population groups are well informed about or able to take advantage of the proper measures for oral health promotion. In addition, in many countries, oral health care needs to be fully integrated into national or community health programmes. Improving oral health is a very challenging objective in developing countries, but also in developed countries, especially with the accelerated aging of the population now underway and intensifying over the coming years.

  18. PLM system support for modular product development

    Bruun, Hans Peter Lomholt; Mortensen, Niels Henrik

    2015-01-01

    A modular design strategy both enables, but also demands, parallelism in design activities and collaboration between a diversity of disciplines in companies, which often involves supporting computer-based tools for enhancing interaction, design management, and communication. Product data management (PDM) and product lifecycle management (PLM) systems offer support by automating and managing some of the operational complexity of modular design activities. PLM system tools are used for handling a variety of product definitions, to manage workflow of development activities, and to measure relational properties such as cost and performance. Companies often use a PLM tool for management of CAD files, documents, and drawings, but they do not take advantage of the full potential of the PLM system to support the development activities of modular product designs. The key result of this paper is the description of an empirical tested approach using a visual product architecture representation in combination with a PLM system to support the development of a product family of products. The results from the study encompass new PLM capabilities for handling multiple product structures, visualising multiple architectural views on products, controlling interfaces, and quantifying and communicating the status and progress of product-related resources. © 2014 Elsevier B.V.

    Critical parts of the software development life cycle are concerned with eliciting, understanding, and managing requirements. Though the literature on this subject dates back for several decades, practicing effective requirements development remains a current and challenging area. Some projects flourish with a requirements development process (RDP) that is implicit and informal, but this approach may be overly risky, particularly for large projects that involve multiple individuals, groups, and systems over time. At Partners HealthCare System in Boston, Massachusetts, we have applied a more formal approach for requirements development to the Patient Computing Project. The goal of the project is to create web-based software that connects patients electronically with their physician's offices and has the potential to improve care efficiency and quality. It is a large project, with over 500 function points. Like most technological innovation, the successful introduction of this system requires as much attention to understanding the business needs and workflow details as it does to technical design and implementation. This paper describes our RDP approach, and key business requirements discovered through this process. We believe that a formal RDP is essential, and that informatics as a field must include proficiencies in this area. PMID:11825282

  20. Development of the Medium Energy Linac Systems

    International Nuclear Information System (INIS)

    The main purpose of this project is developing 100-MeV proton linear accelerator (linac) for proton engineering frontier project (PEFP). In the first phase of the PEFP, the development of the 20-MeV linac has successfully finished. Hence the work scope of this project is designing the linac to accelerate proton beams from 20-MeV up to 100-MeV, fabricating the linac up to 45 MeV, fabricating one set of the medium energy beam transport (MEBT) tank, and developing the low level radio frequency (LLRF) system and the control system. The basic role of the new proton accelerator is accelerating 20-mA proton beams from 20 MeV up to 100 MeV. The first step of the design procedure is optimizing and determining the accelerator parameters. The beam loss is also main concern in the design stage. The drift tube (DT) and the quadrupole magnets are designed to be optimized to the new linac design. The other purpose is confirming the new design by fabricating and tuning the drift tube linac (DTL). The 20MeV proton beam divided into two directions. One is supplying the beams to user group by turning on the 45-degree bending magnet. The other is guided into the 100-MeV DTL by tuning off the dipole magnet. That is why the PEFP MEBT located after 20-MeV DTL. The MEBT is realized as two small DTL tanks with three cells and a 45-degree bending magnet. The fabrication of one MEBT tank is another purpose of this project. The other purposes of this project is developing the LLRF system to control the RF signal and control system to monitor and control the vacuum system, magnet power supply, etc

    2005-07-12

    This document reports on the work done by Honeywell Sensing and Control to investigate the feasibility of modifying low cost Commercial Sensors for use inside a PEM Fuel Cell environment. Both stationary and automotive systems were considered. The target environment is hotter (100 C) than the typical commercial sensor maximum of 70 C. It is also far more humid (100% RH condensing) than the more typical 95% RH non-condensing at 40 C (4% RH maximum at 100 C). The work focused on four types of sensors, Temperature, Pressure, Air Flow and Relative Humidity. Initial design goals were established using a market research technique called Market Driven Product Definition (MDPD). A series of interviews were conducted with various users and system designers in their facilities. The interviewing team was trained in data taking and analysis per the MDPD process. The final result was a prioritized and weighted list of both requirements and desires for each sensor. Work proceeded on concept development for the 4 types of sensors. At the same time, users were developing the actual fuel cell systems and gaining knowledge and experience in the use of sensors and controls systems. This resulted in changes to requirements and desires that were not anticipated during the MDPD process. The concepts developed met all the predicted requirements. At the completion of concept development for the Pressure Sensor, it was determined that the Fuel Cell developers were happy with off-the-shelf automotive pressure sensors. Thus, there was no incentive to bring a new Fuel Cell Specific Pressure Sensor into production. Work was therefore suspended. After the experience with the Pressure Sensor, the requirements for a Temperature Sensor were reviewed and a similar situation applied. Commercially available temperature sensors were adequate and cost effective and so the program was not continued from the Concept into the Design Phase.

  3. Development of evaluation system for flashing erosion

    International Nuclear Information System (INIS)

    Liquid droplet impingement erosion (LDI) is defined as an erosion phenomenon caused by high-speed droplet attack in a wet steam flow, and sometimes observed in a steam piping system of a power plant. In our previous researches, we have developed an LDI evaluation system to evaluate the thinning shape due to LDI on a steam piping within a practically acceptable time. However, present system is not applicable to LDI on a hot-water piping due to flashing phenomena (flashing erosion) because it is difficult to calculate the flashing flow due to sudden phase change and critical flow rate evaluation models needed for LDI evaluation system are not verified in wet steam region. Therefore, in this study, we tried to develop a new flow calculation code for flashing flow and to verify the critical flow rate evaluation models in wet steam region. For flashing flow simulation, based on a present CFD code, pre-conditioning method was adopted to achieve the stable calculation of the water region, and extended look-up table including from low-pressure water to high-pressure dry steam was incorporated. Finally, a new CFD code water-steam flow was developed. Several benchmark tests were conducted and those results show this new code can reproduce the flashing phenomena and is applicable from the very low-speed flow to supersonic flow. Then, HEM model for critical mass flow rate was verified with flashing and wet steam experiments and CFD calculations, and incorporated into LDI evaluation system to extend applicable region of the evaluation system into flashing erosion.

    2015-01-01

    Industrial strain development requires system-wide engineering and optimization of cellular metabolism while considering industrially relevant fermentation and recovery processes. It can be conceptualized as several strategies, which may be implemented in an iterative fashion and in different orders. The key challenges have been the time-, cost- and labor-intensive processes of strain development owing to the difficulties in understanding complex interactions among the metabolic, gene regulatory and signaling networks at the cell level, which are collectively represented as overall system performance under industrial fermentation conditions. These challenges can be overcome by taking systems approaches through the use of state-of-the-art tools of systems biology, synthetic biology and evolutionary engineering in the context of industrial bioprocess. Major systems metabolic engineering achievements in recent years include microbial production of amino acids (L-valine, L-threonine, L-lysine and L-arginine), bulk chemicals (1,4-butanediol, 1,4-diaminobutane, 1,5-diaminopentane, 1,3-propanediol, butanol, isobutanol and succinic acid) and drugs (artemisinin).

  15. Development of severe accident training support system

    International Nuclear Information System (INIS)

    In order for appropriate decision-making during plant operation and management, the professional knowledge, expert's opinion, and previous experiences as well as information for current status are utilized. The operation support systems such as training simulators have been developed to assist these decision-making process, and most of them cover from normal operation to emergency operation because of the very low frequency of severe accident and of uncertaintics included in severe accident phenomena and scenarios. However, the architectures for severe accident management are being established based on severe accident management guidelines in some developed countries. Recentrly, in Korea, as teh severe accident management guideline was developed, the basis for establishing severe accident management architecture is prepared and this leads to the development of tool for systematic education and training for personnel related to severe accident management. The severe accident taining support system thus is developed to assist decision-making during execution of severe accident management guidelines by providing plant status information, prefessional knowledge for phenomena and scenarios, expected behavior for strategy execution, and so on

    With the retirement of the Space Shuttle, NASA is seeking to reinvigorate the national space program and recapture the public s interest in human space exploration by developing missions to the Moon, near-earth asteroids, Lagrange points, Mars, and beyond. The would-be successor to the Space Shuttle, NASA s Constellation Program, planned to take humans back to the Moon by 2020, but due to budgetary constraints was cancelled in 2010 in search of a more "affordable, sustainable, and realistic" concept2. Following a number of studies, the much anticipated Space Launch System (SLS) was unveiled in September of 2011. The SLS core architecture consists of a cryogenic first stage with five Space Shuttle Main Engines (SSMEs), and a cryogenic second stage using a new J-2X engine3. The baseline configuration employs two 5-segment solid rocket boosters to achieve a 70 metric ton payload capability, but a new, more capable booster system will be required to attain the goal of 130 metric tons to orbit. To this end, NASA s Marshall Space Flight Center recently released a NASA Research Announcement (NRA) entitled "Space Launch System (SLS) Advanced Booster Engineering Demonstration and/or Risk Reduction." The increased emphasis on affordability is evident in the language used in the NRA, which is focused on risk reduction "leading to an affordable Advanced Booster that meets the evolved capabilities of SLS" and "enabling competition" to "enhance SLS affordability. The purpose of the work presented in this paper is to perform an independent assessment of the elements that make up an affordable and realistic path forward for the SLS booster system, utilizing advanced design methods and technology evaluation techniques. The goal is to identify elements that will enable a more sustainable development program by exploring the trade space of heavy lift booster systems and focusing on affordability, operability, and reliability at the system and subsystem levels5. For this study, affordability is defined as lifecycle cost, which includes design, development, test, and engineering (DDT&E), production and operational costs (P&O). For this study, the system objectives include reducing DDT&E schedule by a factor of three, showing 99.9% reliability, flying up to four times per year, serving both crew and cargo missions, and evolving to a lift capability of 130 metric tons.3 After identifying gaps in the current system s capabilities, this study seeks to identify non-traditional and innovative technologies and processes that may improve performance in these areas and assess their impacts on booster system development. The DDT&E phase may be improved by incorporating incremental development testing and integrated demonstrations to mitigate risk. To further reduce DDT&E, this study will also consider how aspects of the booster system may have commonality with other users, such as the Department of Defense, commercial applications, or international partners; by sharing some of the risk and investment, the overall development cost may be reduced. Consideration is not limited to solid and liquid rocket boosters. A set of functional performance characteristics, such as engine thrust, specific impulse (Isp), mixture ratio, and throttle range are identified and their impacts on the system are evaluated. This study also identifies how such characteristics affect overall life cycle cost, including DDT&E and fixed and variable P&O.

    1993-09-01

    The System for Anomaly and Failure Detection (SAFD) algorithm was developed as an improvement over the current redline system used in the Space Shuttle Main Engine Controller (SSMEC). Simulation tests and execution against previous hot fire tests demonstrated that the SAFD algorithm can detect engine failures as much as tens of seconds before the redline system recognized the failure. Although the current algorithm only operates during steady state conditions (engine not throttling), work is underway to expand the algorithm to work during transient conditions. This task assignment originally specified developing a platform for executing the algorithm during hot fire tests at Technology Test Bed (TTB) and installing the SAFD algorithm on that platform. Two units were built and installed in the Hardware Simulation Lab and at the TTB in December 1991. Since that time, the task primarily entailed improvement and maintenance of the systems, additional testing to prove the feasibility of the algorithm, and support of hot fire testing. This document addresses the work done since the last report of June 1992. The work on the System for Anomaly and Failure Detection during this period included improving the platform and the algorithm, testing the algorithm against previous test data and in the Hardware Simulation Lab, installing other algorithms on the system, providing support for operations at the Technology Test Bed, and providing routine maintenance.

    We present our experiences in managing the development cycles of the control systems for ANKA and the ALMA Common Software. Our team consists practically only of undergraduate students. Stimulating and rewarding the students with cutting-edge technologies and travel to conferences like this and installation fieldwork are an important positive factor in raising their motivation. However, building any system with a group of inexperienced students is quite a challenging task. Many problems occur with planning deadlines and missing them, organizing and managing development, sources, and documentation and also when dealing with conventional program management rules. To cope with them, we use many tools: CVS for versioning and source archiving, Bugzilla for keeping our bugs in order, a to-do list for managing tasks, an activity log and also many other programs and scripts, some found on the Internet and some made by ourselves. In the end, we had to become organized like a professional company. Documentation and dem...

In the following time a computers for account, spectrometric and weighing equipment for NDA, TID and other office equipment were delivered. Development of a number of documents concerning regulation of NM handling, IAEA inspectors cooperation, reporting was conducted under ORNL support. NMCA custodians were participants of many training courses held in Kazakhstan, NIS, LANL, NRC. The computerized NMCA system 'AIMAS' developed in ANL and delivered to the Institute was implemented successfully in 1995. During some followed years the 'AIMAS' system was modified step by step and spread to other nuclear facilities of Kazakhstan and Uzbekistan under DOE support. The important element of supporting of SSAC development in Kazakhstan is funding and providing with methodic of annual workshops-conferences for NMCA custodians from Kazakhstan and Uzbekistan. These meetings are conducted continuously on the all nuclear facilities so that the NMCA specialists have a chance to meet their progress in NMCA area. Last such meeting was conducted in August 2005 at the Institute of Atomic Energy. (author)

    2013-01-01

    Development of the central nervous system relies on the generation of specialized cell types in a tightly controlled spatial and temporal order from neural progenitor cells. Morphogen molecules, secreted by defined sources, spatially organize neural progenitors by inducing discrete expression patterns of cell fate determinant genes in a concentration-dependent manner. The combinatorial expression of these patterning genes defines distinct progenitor domains from which specific neuronal subtyp...

    The SNS Extraction Fast Kicker System is a very high power, high repetition rate pulsed power system. It was design and developed at Brookhaven National Laboratory. This system will consist of fourteen identical high voltage, high current modulators, and their auxiliary control and charging systems. The modulators will drive fourteen extraction magnet sections located inside of the SNS accumulator ring. The required kicker field rise time is 200 ns, a pulse flattop of 700 ns, a pulse repetition rate of 60 pulse-per-second. A 2500 Ampere per modulator output is required to reach the extraction kicker magnetic field strength. This design features a Blumlein Pulse-Forming-Network based topology, a low beam impedance termination, a fast current switching thyratron, and low inductance capacitor banks. It has a maximum charging voltage of 50kV, an open circuit output of 100kV, and a designed maximum pulsed current output of 4kA per modulator. The overall system output will be multiple GVA with 60 Pulse-per-second repetition rate. A prototype modulator has been successfully built and tested well above the SNS requirement. The modulator system production is in progress.

    Full Text Available The integration of health and safety, environmental and quality (HSEQ management systems has become a current topic in the 21st century, as the need for systems thinking has grown along with the number of management system standards. This study aims to map current developments and trends in integrated HSEQ management. Three viewpoints are taken: the current state of the main HSEQ management standards, research literature on integrated management systems (IMS, and a case study of an industry-led HSEQ cluster in Northern Finland. The results demonstrate that some of the most prominent current trends are the harmonization of the high level structure of management systems by ISO, the evaluation of IMS, accounting for the supply chain in HSEQ issues, and sustainability and risk management. The results of the study can be used by practitioners to get a view of the current state of HSEQ management systems and their integration, and by researchers to seek out potential directions for HSEQ and IMS related research.

  15. Radiation risks to the developing nervous system

    International Nuclear Information System (INIS)

    A symposium dealing with 'Radiation Risks to the Developing Nervous System' held at Neuherberg, June 18-20, 1985 was organised by the Radiation Protection Programme of the Commission of the European Communities and the Gesellschaft fuer Strahlen- und Umweltforschung mbH. The proceedings of this symposium present up-to-date information on the development of the nervous system and the modifications caused by prenatal radiation there upon. A large part of the proceedings is devoted to the consequences of prenatal irradiation in experimental animals with respect to alterations in morphology, biochemistry and behaviour, to the influence of dose, dose rate and radiation quality and to the question whether damage of the brain can arise from a synergistic action of radiation together with other agents. Since animal models for damage to the human central nervous system have inherent short-comings due to the differences in structure, complexity and development it is discussed how experimental studies could be applied to the human situation. The most recent data on persons exposed in utero at Hiroshima and Nagasaki are reviewed. A round table discussion, published in full, analyses all this information with a view to radiation protection, and defines the areas where future studies are needed. Separate abstracts were prepared for papers in these proceedings. (orig./MG)

    2016-01-01

    The development of new drug therapies requires substantial and ever increasing investments from the pharmaceutical company. Ten years ago, the average time from early target identification and optimization until initial market authorization of a new drug compound took more than 10 years and involved costs in the order of one billion US dollars. Recent studies indicate even a significant growth of costs in the meanwhile, mainly driven by the increasing complexity of diseases addressed by pharmaceutical research.Modeling and simulation are proven approaches to handle highly complex systems; hence, systems medicine is expected to control the spiral of complexity of diseases and increasing costs. Today, the main focus of systems medicine applications in industry is on mechanistic modeling. Biological mechanisms are represented by explicit equations enabling insight into the cooperation of all relevant mechanisms. Mechanistic modeling is widely accepted in pharmacokinetics, but prediction from cell behavior to patients is rarely possible due to lacks in our understanding of the controlling mechanisms. Data-driven modeling aims to compensate these lacks by the use of advanced statistical and machine learning methods. Future progress in pharmaceutical research and development will require integrated hybrid modeling technologies allowing realization of the benefits of both mechanistic and data-driven modeling. In this chapter, we sketch typical industrial application areas for both modeling techniques and derive the requirements for future technology development. PMID:26677181

    In the frame of the Exploration Programs, a soft landing on the planet surface is foreseen. To ensure a successful final landing phase, a landing system by using leg tripod design landing legs with adequate crushable damping system was selected, capable of absorbing the residual velocities (vertical, horizontal and angular) at touch- down, insuring stability. TAS-I developed a numerical non linear dynamic methodology for the landing impact simulation of the Lander system by using a commercial explicit finite element analysis code (i.e. Altair RADIOSS). In this paper the most significant FE modeling approaches and results of the analytical simulation of landing impact are reported, especially with respect to the definition of leg dimensioning loads and the design update of selected parts (if necessary).

  18. Development of the environmental neutron detection system

    2002-01-01

    Environmental neutron detection system was proposed and developed. The main goal of this system was set to detect fast and thermal neutrons with the identical detectors setup without degraders. This system consists of a sup 1 sup 0 B doped liquid scintillator for n detection and CsI scintillators for simultaneous gamma emission from sup 1 sup 0 B doped in the liquid scintillator after the n capture reaction. The first setup was optimized for the thermal n detection, while the second setup was for the fast n detection. It was shown that the thermal n flux was obtained in the first setup by using the method of the gamma coincidence method with the help of the Monte Carlo calculation. The second setup was designed to improve the detection efficiency for the fast n, and was shown qualitatively that both the pulse shape discrimination and the coincidence methods are efficient. There will be more improvements, particularly for the quantitative discussion.

    Silicon carbide (SiC) based gas sensors have significant potential to address the gas sensing needs of aerospace applications such as emission monitoring, fuel leak detection, and fire detection. However, in order to reach that potential, a range of technical challenges must be overcome. These challenges go beyond the development of the basic sensor itself and include the need for viable enabling technologies to make a complete gas sensor system: electrical contacts, packaging, and transfer of information from the sensor to the outside world. This paper reviews the status at NASA Glenn Research Center of SiC Schottky diode gas sensor development as well as that of enabling technologies supporting SiC gas sensor system implementation. A vision of a complete high temperature microfabricated SiC gas sensor system is proposed. In the long-term, it is believed that improvements in the SiC semiconductor material itself could have a dramatic effect on the performance of SiC gas sensor systems.

  1. Development of decommissioning engineering support system for fugen. Development of support system during actual dismantlement works

    International Nuclear Information System (INIS)

    The Advanced Thermal Reactor, Fugen Nuclear Power Station was permanently shut down in March 2003, and is now preparing for decommissioning. We have been developing Decommissioning Engineering Support System (DEXUS) aimed at planning optimal dismantlement process and carrying out dismantlement work safely and precisely. DEXUS consists of 'decommissioning planning support system' and 'dismantling support system'. The dismantling support system is developed aiming at using during actual dismantling work. It consists of three subsystems such as 'Worksite Visualization System', 'Dismantling Data Collection System' and 'Generated Waste Management System'. 'Worksite Visualization System' is a support system designed to provide the necessary information to workers during actual dismantlement works. And this system adopts AR (Augmented Reality) technology, overlapping calculation information into real world. 'Dismantling Data Collection System' is to collect necessary data for improving accuracy of decommissioning planning by evaluating work content and worker equipage, work time for dismantlement works. 'Generated Waste Management system' is a system recording necessary information by attaching the barcode to dismantled wastes or the containers. We can get the information of generated waste by recording generation place, generated time, treatment method and the contents. These subsystems enable to carry out reasonable and safe decommissioning of Fugen. In addition, we expect that those systems will be used for decommissioning of other nuclear facilities in the future. (authors)

  4. Developing an information systems strategy for nursing.

    1995-01-01

    With the rapidly changing health care environment and information technology advances, organizations need to engage in strategic, planned change in order to allocate limited resources, achieve the organization's goals, and fulfill its mission [1]. One of the most important aspects of the organization's planned strategies for change concerns the information systems. The involvement of the nursing department in this process is critical. This poster presentation will communicate how nurses can develop an information systems strategic plan that will enable them to play an active role as contributors and vital participants in the strategic and business planning processes for information systems. This information systems strategy for nursing will: a) provide direction and purpose, b) guide nursing in identifying the kinds of information technology needed, c) assist in timely implementation of a system that supports nursing, and d) identify desired outcomes and benefits of an information system. The nursing information systems plan must be built on, and support, the organization's mission and business plan and integrate into the over-all information systems plans [2]. Components of the nursing strategic plan include the nursing mission statement and vision, an assessment of the current environment to identify supporting technology needed to achieve the nursing vision, expectations/anticipated outcomes, environmental considerations, and special staffing/expertise considerations. The nursing vision and mission statement is an articulation of the overall direction and purpose of the nursing organization. An assessment of the nursing organization, problem areas, opportunities for growth, the physical environment, existing systems, communications requirements, and resources is carried out to help identify areas where new technologies and automated methods of managing information could be applied. Special staffing and expertise not currently available in the organization, but necessary to the successful implementation of the plan, should be identified, and plans for filling those needs should be included in the planning and prioritization process. Based on the mission and assessment findings, goals or anticipated outcomes are developed. These goals must be realistic, financially feasible, and logistically achievable; they should also provide direction for action and decision-making [3]. Measurable objectives and detailed action plans can then be developed from these goals when implementation of this aspect of the strategic plan is begun. It is especially important, even at a strategic planning level, to consider change management techniques, including specific steps to involve individuals who will be affected by the change and to ensure open communication throughout the process. Efforts to collaborate with all affected departments and to offer input and educational opportunities to the various members of the health care team should be included in the strategic plan. A business plan describing the mission, goals, and objectives for a specific system implementation is the final step in the strategic planning process. The business plan includes expected outcomes and cost justification and may be done in cooperation with other departments (in the organization) that will be involved with this system. The business plan is used to communicate the information system's needs to the administration and governing board of the organization. With a good information systems strategy, nursing will be prepared to make more timely and better informed decisions related to applying information technology within the nursing department. The end results of this planning should be evident in the improved utilization of information technology to support the nursing vision and mission. PMID:8591465

  5. Development of an intellectual maintenance management system. Development of trouble detection and troubleshooting evaluation system

    International Nuclear Information System (INIS)

    Many research activities are conducted to enhance cost performance and safety of nuclear power plants operation and maintenance. Concept of autonomous operating system to equal the role of operators and of maintenance personnel with artificial intelligence and autonomous robots has been developed. An intellectual maintenance management system has been developed to be equipped with decision making functions of maintenance personnel. The intellectual maintenance management system is in charge of maintenance function of an autonomous plant, which consists of plant-wide monitoring, evaluation of component integrity, and scheduling of maintenance activities. In other words, this system should be equipped with preventive maintenance and corrective maintenance functions those are currently loaded on personnel. In this report, we discussed condition monitoring maintenance in the preventive maintenance. We also reported a sensor validation system development for machinery condition monitoring and diagnosis. We adopted distributed and cooperative system construction technique, which is expected recently in applications to large-scale plants. This system has inter-agent communication function for signal transmission and reception among distributed physics models of machineries. The system has been constructed for water/steam system of the LMFBR power plant. The system has been validated to be capable of cooperative sensor validation by the distributed set of agents, with quantitative indication of sensor deviation based on a newly developed fuzzy algorithm with inter-agent cooperation. The derived reference parameter value from the inter-agent evaluations also stands for the alternative measurement to the malfunctioned sensor. (author)

  6. Implementing Life Cycle Assessment in systems development.

    Bhander, Gurbakhash Singh; Hauschild, Michael Zwicky

    2003-01-01

    Today's industry is being forced to consider the environmental performance of its products concurrently with traditional requirements such as quality, price or functional performance. The Life Cycle Assessment (LCA) technique has been identified as a powerful tool to calculate environmental impacts derived from products and system, and calculate resource consumptions. However, the complexity of LCA poses restrictions to its use in current product and system development given the need for a reduction in product development cycle time which is needed to meet the increasing competitive pressures and the rapid changes in markets for many products. The overall aim of the paper is to provide an understanding of the environmental issues involved in the early stages of product development and the capacity of life cycle assessment techniques to address these issues. The paper aims to outline the problems for the designer in evaluating the environmental benignity of the product from the outset and to provide the designer with a framework for decision support based on the performance evaluation at different stages of the design process. The overall aim of this paper is to produce an in-depth understanding of the barriers to implementation of LCA by developers of products, and of the opportunities for introducing environmental criteria in the design process through meeting the information requirements of the designer on the different life cycle stages, producing an in-depth understanding of the attitudes of practitioners among product developers to the subject area, and an understanding of possible future directions for product development. An Environmentally Conscious Design method is introduced and trade-offs are presented between design degrees of freedom and environmental solutions. It also discusses a number of possibilities which can be introduced in the design stage compared to the other life cycle stages of the product system. The paper collects experiences and ideas around the state-of-the-art in eco-design, from literature and personal experience and further provides eco-design life cycle assessment strategies. The paper reviews the current environmental evaluation practices with respect to product life cycles. As a number of deficiencies in LCA are identified, strategies are presented to provide a solution to many of the deficiencies. The result of the paper is a definition of the requirements for performance measurement techniques and a performance measurement environment necessary to support life cycle evaluation throughout the evaluation of early stages of a product system.

  7. Development of Vertical Cable Seismic System (2)

    Asakawa, E.; Murakami, F.; Tsukahara, H.; Ishikawa, K.

    2012-12-01

    The vertical cable seismic is one of the reflection seismic methods. It uses hydrophone arrays vertically moored from the seafloor to record acoustic waves generated by surface, deep-towed or ocean bottom sources. Analyzing the reflections from the sub-seabed, we could look into the subsurface structure. This type of survey is generally called VCS (Vertical Cable Seismic). Because VCS is an efficient high-resolution 3D seismic survey method for a spatially-bounded area, we proposed the method for the hydrothermal deposit survey tool development program that the Ministry of Education, Culture, Sports, Science and Technology (MEXT) started in 2009. We are now developing a VCS system, including not only data acquisition hardware but data processing and analysis technique. Our first experiment of VCS surveys has been carried out in Lake Biwa, JAPAN in November 2009 for a feasibility study. Prestack depth migration is applied to the 3D VCS data to obtain a high quality 3D depth volume. Based on the results from the feasibility study, we have developed two autonomous recording VCS systems. After we carried out a trial experiment in the actual ocean at a water depth of about 400m and we carried out the second VCS survey at Iheya Knoll with a deep-towed source. In this survey, we could establish the procedures for the deployment/recovery of the system and could examine the locations and the fluctuations of the vertical cables at a water depth of around 1000m. The acquired VCS data clearly shows the reflections from the sub-seafloor. Through the experiment, we could confirm that our VCS system works well even in the severe circumstances around the locations of seafloor hydrothermal deposits. We have carried out two field surveys in 2011. One is a 3D survey with a boomer for a high-resolution surface source and the other one for an actual field survey in the Izena Cauldron an active hydrothermal area in the Okinawa Trough. Through these surveys, we have confirmed that the uncertainty in the locations of the source and of the hydrophones in water could lower the quality of subsurface image. It is, therefore, strongly necessary to develop a total survey system that assures an accurate positioning and a deployment techniques. In case of shooting on sea surface, GPS navigation system are available, but in case of deep-towed source or ocean bottom source, the accuracy of shot position with SSBL/USBL is not sufficient for the very high-resolution imaging as requested for the SMS survey. We will incorporate the accurate LBL navigation systems with VCs. The LBL navigation system has been developed by IIS of the University of Tokyo. The error is estimated less than 10cm at the water depth of 3000m. Another approach is that the shot points can be calculated using the first break of the VCS after the VCS locations are estimated by slant-ranging from the sea surface. Our VCS system has been designed as a survey tool for hydrothermal deposit, but it will be also applicable for deep water site surveys or geohazard assessment such as active faults.

  8. Development of superconducting ship propulsion system

    International Nuclear Information System (INIS)

    When we plan displacement-type monohull high speed vessels, it is difficult to get the hull form with the wave-making resistance minimum, because the stern shape is restricted by arrangement of propulsive machines and shafts. A small-sized and light-weight propulsive machines will reduce the limit to full form design. Superconducting technology will have capability of realizing the small-sized and light-weight propulsion motor. The superconducting electric propulsion system which is composed of superconducting propulsion motors and generators, seems to be an ideal propulsion system for future vehicles. We have constructed a 480 kW superconducting DC homopolar laboratory test motor for developing this propulsion system. The characteristic of this motor is that it has a superconducting field winding and a segmented armature drum. The superconducting field winding which operates in the persistent current mode, is cooled by a condensation heat exchanger and helium refigerating system built into the cryostat of the superconducting field winding. The operating parameters of this motor agreed well with the design parameters. Using the design concepts of this motor, we have conceptually designed a 150,000-200,000 PS superconducting electric propulsive system for a displacement-type monohull high speed ship. (author)

  9. Development of JRR-4 operation support system

    International Nuclear Information System (INIS)

    The Japan Research Reactor No.4 (JRR-4) is a light water moderated and cooled, graphite reflected, pool-type reactor with the thermal output of 3500 kW. In February 1996, a work on core modification from high-enriched fuels to low-enriched ones was started and the work on modification was completed in May 1998. As a part of the work, Operation Support System (OSS) was adopted for the purpose of reducing load of operator, preventing operator's error and supplying operation data to users. In this paper, JRR-4 Operation Support System's configuration, characteristics and development process are described. OSS consists mainly of a workstation (WS), ?XL and Personal Computer (PC). WS is used for collection of operation data. ?XL is used for cooling system control and PC is used for operators' support. All of the program applications used in WS, ?XL and PC are designed to make sure of high flexibility for the demands on modification from operators and new operation modes. The result of adopting this system, the consolidation monitoring, automation of part of reactor operation and data management were realized. In addition, the cooling control system was compacted.

  10. Development of cost-benefit analysis system

    International Nuclear Information System (INIS)

    In order to promote the FDR development, it is necessary to see various benefits brought by introduction of FBR from multiple perspectives and have a good grasp of such benefits quantitatively and an adequate R and D investment scale which corresponds with them. In this study, the structured prototype in the previous study was improved to be able to perform cost-benefit analysis. An example of improvement made in the system is addition of subroutine used for comparison between new energy and benefits brought by introduction of FBR with special emphasis on addition of logic for analyzing externality about the new energy. Other improvement examples are modification of the Conventional Year Expense Ratio method of power generation cost to Average Durable Year Cost method, addition of database function and turning input data into database, and reviewing idea on cost by the type of waste material and price of uranium. The cost-benefit analysis system was also restructured utilizing Microsoft ACCESS so that it should have a data base function. As the result of the improvement mentioned above, we expect that the improved cost-benefit analysis system will have higher generality than the system before; therefore, great deal of benefits brought by application of the system in the future is expected.

    The global environment is a complex and dynamic system. Earth system modeling is needed to help understand changes in interacting subsystems, elucidate the influence of human activities, and explore possible future changes. Integrated assessment of environment and human development is arguably the most difficult and most important "systems" problem faced. To illustrate this approach, we present results from the integrated global system model (IGSM), which consists of coupled submodels addressing economic development, atmospheric chemistry, climate dynamics, and ecosystem processes. An uncertainty analysis implies that without mitigation policies, the global average surface temperature may rise between 3.5 °C and 7.4 °C from 1981-2000 to 2091-2100 (90% confidence limits). Polar temperatures, absent policy, are projected to rise from about 6.4 °C to 14 °C (90% confidence limits). Similar analysis of four increasingly stringent climate mitigation policy cases involving stabilization of greenhouse gases at various levels indicates that the greatest effect of these policies is to lower the probability of extreme changes. The IGSM is also used to elucidate potential unintended environmental consequences of renewable energy at large scales. There are significant reasons for attention to climate adaptation in addition to climate mitigation that earth system models can help inform. These models can also be applied to evaluate whether "climate engineering" is a viable option or a dangerous diversion. We must prepare young people to address this issue: The problem of preserving a habitable planet will engage present and future generations. Scientists must improve communication if research is to inform the public and policy makers better. PMID:22706645

    Alkaline desert soils are high in insoluble calcium phosphates but deficient in soluble orthophosphate (Pi) essential for plant growth. In this extreme environment, one adaptive strategy could involve specific associations between plant roots and mineral phosphate solubilizing (MPS) bacteria. The most efficient MPS phenotype in Gram-negative bacteria results from extracellular oxidation of glucose to gluconic acid via the quinoprotein glucose dehydrogenase. A unique bacterial population isolated from the roots of Helianthus annus jaegeri growing at the edge of an alkaline dry lake in the Mojave Desert showed no MPS activity and no gluconic acid production. Addition of a concentrated solution containing material washed from the roots to these bacteria in culture resulted in production of high levels of gluconic acid. This effect was mimicked by addition of the essential glucose dehydrogenase redox cofactor 2,7,9-tricarboxyl-1H-pyrrolo[2,3]-quinoline-4,5-dione (PQQ) but the bioactive component was not PQQ. DNA hybridization data confirmed that this soil bacterium carried a gene with homology to the Escherichia coli quinoprotein glucose dehydrogenase. These data suggest that expression of the direct oxidation pathway in this bacterium may be regulated by signaling between the bacteria and the plant root. The resultant acidification of the rhizosphere may play a role in nutrient availability and/or other ecophysiological parameters essential for the survival of this desert plant. PMID:10568838

    MPS(Moving Particle Semi-implicit) Method is a Lagrangian numerical analysis method, which does not necessary to set the lattice. Thus, it is effective for the analysis with complicated boundary such as free surface flow. On the other hand, since it is possible that particles varying their relative positions in MPS method, it courses a problem of non-uniformity in the spatial distribution of particles, thereby generating pressure fluctuation. Solving the pressure fluctuation problem has now been considered as the most important issue to improve the performance MPS method. So far there are some ways been suggested to solve the problem, but the pressure fluctuation can not be erased fundamentally by any of those. To deal with the problem, Tamai, Koshizuka had proposed a higher-order accuracy differential model that can properly take into account the spatial arrangement of particles. However, this model has just been proposed 2013 and not been well verified when applied to simulation. The present study has firstly comfirmed that compare to the old methods, Tamai, Koshizuka's new model can solve the problem more effectively. Secondly, we try to use the new differential model to do the dam-break simulation which is a classical benchmark for free-surface issues. However, we found that the new model has problems when dealing with the Neumann boundary condition. So we proposed a new way of setting the Neumann boundary condition in order to use the new differential model correctly, and finially got a very good result in the simulation.

    The colloidal CdS quantum dots (QDs) were synthesized with various molar ratios of 3-mercaptopropyltrimethoxysilane (MPS) molecules. The results show that the smaller size of CdS QDs was obtained at the higher molar concentration of MPS. Sol-gel spin coating method was used for deposition of the colloidal nanoparticles on a glass substrate. One pot production method was used to obtain self-assembled thin films of CdS QDs in SiO2 network and the grow kinetics of QDs were investigated. The samples were heat treated at various temperatures to observe the growth of the QDs. The sizes of the QDs were obtained in the range of 2-5 nm depending on the capping agent concentration and heat-treatment temperature. The activation energies for the Ostwald ripening process were found as 38.7, 56.4, 93,1 and 98.6 kJ/mol for the samples containing molar ratio of MPS:Cd = 0.25, 0.50, 1.00 and 2.00 respectively.

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

  16. EU developments of the ITER ECRH system

    International Nuclear Information System (INIS)

    The EU will be providing the largest contribution to the ITER electron cyclotron (EC) heating and current drive (H and CD) system (20 MW, CW at 170 GHz). The contribution includes one third of the H and CD gyrotrons, their associated power supplies and four upper port launcher antennas. In all areas of participation, the EU EC partnership (coordinated by the European Fusion Development Agreement) aims toward advancing the technology, while staying within a specified cost envelope. This is portrayed in the co-axial gyrotron development that offers the potential to double the output power per source (2.0 MW), increasing the delivered power for a fixed number of auxiliary systems. The EU partnerships also attempt to increase performance for the entire EC system, in particular the launching antennas. The proposed front steering launcher design offers greater control of MHD activity than the previous remote steering design and opens up the possibility of an enhanced performance UL. The EC physics requirements are repartitioned between the upper and equatorial launchers for a synergetic balance, which increases the EC physics capabilities while relaxing some of the engineering requirements

    2014-02-01

    Recent investigations show the need for certificating sunglasses to ensure the safety and health to population. The Brazilian Standard ABNT NBR 15111 regulates features to sunglasses, however, there is not a sunglasses certification office in Brazil, therefore, our lab has been developing several equipment for sunglasses testing. This work refers to one of them: the flammability test system for sunglasses in compliance with the NBR 15111. The standard provides requirements for the flammability test procedure which requires that the equipment must operate at a temperature of 650 °C +/- 20 °C the end of a steel rod of 300 mm length and 6 mm diameter should be heated and pressed over the surface of the lenses for five seconds; the flammability is checked by visual inspection. The furnace is made of ceramic. We used a power electronic circuit to control the power in the furnace using ON/OFF mode and for measuring the temperature, we used a K-type thermocouple. A stepper motor with pulley lifts the steel rod. The system reaches the working temperature in 15 minutes for a step input of 61 V in open loop system. The electronics control are under development in order to shorten the time necessary to reach the working temperature and maintain the temperature variation in the furnace within the limits imposed by the standard as next steps.

  18. Advanced systems: Status and development prospects

    International Nuclear Information System (INIS)

    World reserves of coal, uranium, thorium and thermonuclear fuel (deuterium and lithium) are sufficient to provide mankind with energy for many centuries. The rate of increase in demand is unlikely to be a limiting factor, and it would seem that any ''limits to growth'' will be dictated by other, in particular ecological, factors. In the last two decades, world power production has developed a structure in which a predominant place is occupied by oil and gas; this will have to change as a result of the marked depletion of oil resources and the enhanced role played in the fuel balance by power from coal and nuclear fission, on which, it would seem, the long-term growth of world energy production will be based. The contribution of nuclear fission power towards meeting world energy needs will depend on a number of factors, the most important of which from a long-term point of view is the time and rate of introduction of advanced nuclear power systems and fuel cycles with high nuclear fuel surpluses (breeding ratios). The results of almost 30 years of development of nuclear power with thermal-neutron reactors may serve as a basis for the analysis, evaluation and forecasting of the development of advanced systems.

  19. Development of decommissioning system engineering technology

    International Nuclear Information System (INIS)

    In the decommissioning planning stage, it is important to select the optimized decommissioning process considering the cost and safety. Especially the selection of the optimized decommissioning process is necessary because it affects to improve worker's safety and decommissioning work efficiency. The decommissioning process evaluation technology can provide the optimized decommissioning process as constructing various decommissioning scenarios and it can help to prevent the potential accidents as delivering the exact work procedures to workers and to help workers to perform decommissioning work skillfully. It's necessary to measure the radioactive contamination in the highly contaminated facilities such as hot-cells or glove-boxes to be decommissioned for decommissioning planning. These facilities are very high radiation level, so it is difficult to approach. In this case the detector system is preferable to separate the sensor and electronics, which have to locate in the facility outside to avoid the electric noise and worker's radiation exposure. In this project, we developed the remote detection system for radiation measurement and signal transmission in the high radiation area. In order to minimize worker's exposure when decommissioning highly activated nuclear facilities, it is necessary to develop the remote handling tool to perform the dismantling work remotely. Especially, since cutting, measuring, and decontamination works should be performed remotely in the highly activated area, the remote handling tool for conducting these works should be developed. Therefore, the multi-purpose dismantling machine that can measuring dose, facility cutting, and remote handling for maintenance and decommissioning of highly activated facility should be needed

  20. Development of the plutonium oxide vitrification system

    International Nuclear Information System (INIS)

    Repository disposal of plutonium in a suitable, immobilized form is being considered as one option for the disposition of surplus weapons-usable plutonium. Accelerated development efforts were completed in 1997 on two potential immobilization forms to facilitate downselection to one form for continued development. The two forms studied were a crystalline ceramic based on Synroc technology and a lanthanide borosilicate (LaBS) glass. As part of the glass development program, melter design activities and component testing were completed to demonstrate the feasibility of using glass as an immobilization medium. A prototypical melter was designed and built in 1997. The melter vessel and drain tube were constructed of a Pt/Rh alloy. Separate induction systems were used to heat the vessel and drain tube. A Pt/Rh stirrer was incorporated into the design to facilitate homogenization of the melt. Integrated powder feeding and off-gas systems completed the overall design. Concurrent with the design efforts, testing was conducted using a plutonium surrogate LaBS composition in an existing (near-scale) melter to demonstrate the feasibility of processing the LaBS glass on a production scale. Additionally, the drain tube configuration was successfully tested using a plutonium surrogate LaBS glass

    2015-09-01

    In the present study, performance improvements of the particle search and particle interaction calculation steps constituting the performance bottleneck in the moving particle simulation method are achieved by developing GPU-compatible algorithms for many core processor architectures. In the improvements of particle search, bucket loops of the cell-linked list are changed to a loop structure having fewer local variables and the linked list and the forward star of particle search algorithms within a bucket are compared. In the particle interaction calculation, the problem of the ratio of particles within the interaction domain to the neighboring particle candidates being quite low is improved. By these improvements, a performance efficiency of 24.7 % can be achieved for the first-order polynomial approximation scheme using NVIDIA Tesla K20, CUDA-6.5, and double-precision floating-point operations.

    Since its first ion beam, the GANIL accelerator has been driven by a Control System built around a minicomputer MITRA 125 and a distributed intelligence consisting of programmable Controllers and INTEL 8080 equipped autonomous CAMAC Controllers. After a brief description of the GANIL Control System, this paper will lay emphasis on the major improvements undertaken along four main directions: a) Upgrading the Control Computer. b) Introducing more powerful local intelligence. A microprocessorized autonomous CAMAC Controller called ''DIVA 68C'' using the 68000 microprocessor embedded in a VME card has been developed. Also, the 68000 will be used in a general purpose CAMAC module, the first application of which is to replace the existing data link modules. (c) Making human-machine dialog smarter with use of color graphic terminals. d) Meeting the requirements of the coming second injector. In this purpose a fully equipped auxiliary console is being installed near the main console for operation by summer 1985

  5. Development of energy and transport systems

    International Nuclear Information System (INIS)

    Economic development and the advancement of technology is presented as a process of substituting old forms of satisfying human needs by new ones or, more precisely, as a sequence of such substitutions. The examples, reconstructed from historical records, describe the quantitative, technological changes in energy and transport systems. The analysis of historical replacement of old by new technologies has shown that most of these processes can be described by simple rules that are captured in the logistic substitution model, and that technological substitution, expressed in terms of market shares, follows characteristic S-shaped curves. To illustrate the properties of the approach examples are given of how new energy forms replaced their predecessors. To further explore the method similar substitution processes in transport systems are described. 21 refs, 23 figs, 1 tab

    Full Text Available We present a progress report on the development of information system of lunar crescent astronomical observations which will be largely accessible for public domain. This consists of calculations of the Moon’s ephemeris as well as systematic real-time lunar crescent observations. A well suited small telescope, equipped with a simple digital detector, is connected to a server to provide information on lunar crescent observations. The system has been used and worked well. The only constraint is poor weather condition. Network of small telescopes, installed at various locations in Indonesia, are currently planned to provide plethora of data. In the long term, this will be used to help to determine the astronomical visibility criteria of lunar crescent for Islamic calendar.

  7. Development of the Open Items Tracking System

    International Nuclear Information System (INIS)

    The West Valley Demonstration Project, located on the site of the only commercial nuclear fuel reprocessing facility to have operated in USA, has the directed objectives of solidifying the high-level radioactive waste into a durable, solid form for shipment; decontaminating and decommissioning the tanks and facilities; and disposing of the resulting low-level and transuranic wastes. Since an escalating trend of open work items was noticed in the Fall of 1988, and there was no control mechanism for tracking and closing the open items, a Work Control System was developed for this purpose. It is self-contained system on a mainframe ARTEMIS 9000, which tracks, monitors, and closes out external commitments in a timely manner. Audits, surveillances, site appraisals, preventive maintenance, instrument calibration recall, and scheduling are covered

    2004-01-01

    To achieve NASA's ambitious mission objectives for the future, aircraft and spacecraft will need intelligence to take the correct action in a variety of circumstances. Vehicle intelligence can be defined as the ability to "do the right thing" when faced with a complex decision-making situation. It will be necessary to implement integrated autonomous operations and low-level adaptive flight control technologies to direct actions that enhance the safety and success of complex missions despite component failures, degraded performance, operator errors, and environment uncertainty. This paper will describe the array of technologies required to meet these complex objectives. This includes the integration of high-level reasoning and autonomous capabilities with multiple subsystem controllers for robust performance. Future intelligent systems will use models of the system, its environment, and other intelligent agents with which it interacts. They will also require planners, reasoning engines, and adaptive controllers that can recommend or execute commands enabling the system to respond intelligently. The presentation will also address the development of highly dependable software, which is a key component to ensure the reliability of intelligent systems.

    A differential absorption lidar system (DIAL) based on a continuously tunable optical parametric amplifier (OPA) pumped by a Nd : YAG laser (200 mJ at ?=355 nm) operating at a maximum pulse repetition rate of 100 Hz has been developed. The system provides continuously tunable coherent radiation in the Visible-near IR range (0.4-2.5 ?m), allowing to perform DIAL measurements in a spectral region where most of atmospheric constituents and pollutants display absorption lines. The spectral width of the OPA system is line-narrowed by using a master oscillator dye laser as seeder, achieving a linewidth of 0.04 cm -1 (FWHM), a spectral purity larger than 99% and a frequency stability better than 1 pm h -1, with an output energy in the IR of 1-10 mJ. The OPA system was used to perform DIAL measurements in the lower troposphere. Preliminary results in terms of water vapor content and aerosol backscattering profiles are presented and discussed.

  10. Development of the High Energy Linac Systems

    International Nuclear Information System (INIS)

    The main purpose of this project is studying the extension plan of the proton engineering frontier project (PEFP) 100-MeV Linac. It includes three categories. One is studying operation plan of the PEFP linac and its extended accelerators, and developing a distribution system of 100-MeV proton beams with a laser striping. Other is designing superconducting RF (SRF) modules and fabricating and testing a copper cavity model. The other is designing a rapid cycling synchrotron (RCS). The operation scheme of the PEFP linac is related to the optimization in the operation of the 100-MeV linac, 200-MeV SRF, and RCS. We studied several operational method to increase the validity of the accelerators. The beam distribution system has two roles. One is supplying proton beams of 100 MeV to the user group. The laser stripping of the negative hydrogen atoms is used in this case. The other beams are directed to the next high energy accelerators. This study contributes to increase the availability of the proton beams. The SRF is one of candidates to extend the PEFP linac system. Since the accelerating gradient of the SRF is much higher than the normal conducting accelerator, a lot of institutes over the world are developing the SRF structure. Main purposes are designing an SRF module, fabricating and testing an copper model which has similar material properties as Nb of the usual SRF cavity material. The RCS is a synchrotron whose injector is the PEFP 100-MeV linac. Main purposes are determining the lattice structure, studying the fast and slow extraction system, simulating beam behavior in the designed synchrotron. The RCS will be used as the spallation neutron source and tools in the basic and applied science including medical application

    Despite widespread aims to strengthen the Health Information System (HIS) as a tool for decentralised health care, there is a strong tendency in most developing countries that the HIS continues to reflect the central level's needs and requirements. The traditional design approach with little or no...... end user involvement results in a centralised HIS with an extensive, somewhat inappropriate, but also inflexible set of standards. Consequently, the HIS is not very useful for the wished-for decentralisation of health services, and there is an urgent need to redesign the existing HIS in order to make...

  17. EU Developments of the ITER ECRH System

    International Nuclear Information System (INIS)

    The electron cyclotron (EC) heating and current drive (H (and) CD) system of ITER will deliver 20 MW/CW in the plasma at 170 GHz for H (and) CD in addition to 2.5 MW/3 s at 120 GHz for plasma start-up. The EC system is composed of power supplies (PS), up to 24 H (and) CD gyrotrons (1 to 2 MW tubes), 3 start-up gyrotrons (1 MW tubes), 24 transmission lines and two sets of launching antennas: equatorial (EL) and upper (UL) launchers. Under the present ITER procurement package the EU is responsible for one third of the H (and) CD 170 GHz gyrotrons, all PSs associated with the H (and) CD system, and the whole set (4) of upper launchers. In all areas of participation, the EU EC partnership (coordinated by the European Fusion Development Association - EFDA) aims toward advancing the technology of each of these subsystems. For example, procurement of Pulse Step Modulator (PSM) HVPS is under consideration, which might have equivalent costs to the present ITER design (thyristor HVPS and HV series switch), but with an increased flexibility in operation and variation in the EC power waveform. The EU is at the forefront in gyrotron research and is developing a 2 MW CW 170 GHz coaxial cavity gyrotron offering an increase in output power while maintaining moderate power densities in the gyrotron cavity and collector. THALESR in collaboration with its EFDA partners (FZK, CRPP, TEKES) is manufacturing a series of prototype tubes in three phases of typically 1 s, 100 s and then CW pulse capacity (? 2010). A 2 MW, CW gyrotron test facility is being built at CRPP that will be used to develop the 2 MW coaxial tube, in addition to testing various components required by the EC system. EFDA has undertaken a parallel development of two launcher options: front (FS) and remote (RS) steering, with the aim of providing an optimum launcher for ITER weighing EC physics aspects and operation reliability. The FS launcher (ITER reference design) offers a significant enhancement in physics performance, while the RS (backup solution) offers a remote steering mirror far from the plasma for simplified ex-vessel maintenance access. The principle role of the UL is to stabilise neoclassical tearing modes. However, an enhanced performance UL launcher is under investigation by EFDA, seeking synergy between the EL and UL that would extend the physics potential of both launchers for an enhanced ITER EC physics performance, while at the same time relax some of the engineering requirements.

  18. Development of a THz spectroscopic imaging system

    International Nuclear Information System (INIS)

    We have developed a real-time THz imaging system based on the two-dimensional (2D) electro-optic (EO) sampling technique. Employing the 2D EO-sampling technique, we can obtain THz images using a CCD camera at a video rate of up to 30 frames per second. A spatial resolution of 1.4 mm was achieved. This resolution was reasonably close to the theoretical limit determined by diffraction. We observed not only static objects but also moving ones. To acquire spectroscopic information, time-domain images were collected. By processing these images on a computer, we can obtain spectroscopic images. Spectroscopy for silicon wafers was demonstrated

  19. Progress in coating development for fusion systems

    International Nuclear Information System (INIS)

    Development of effective and reliable coatings is a key to the viability of most, if not all, fusion blanket systems. The specific purpose and requirements of the coatings vary widely, depending on the blanket concept. The efforts on coating development to date have focused primarily on electrically insulating coatings for the self-cooled lithium concepts with a vanadium alloy structure, and the tritium barrier coatings for the water-cooled, Pb-Li (WCLL) breeder concepts with ferritic steel structures. Although other coating materials are under consideration, most of the effort on the electrically insulating coatings has focused on CaO and AlN coatings on V-4Cr-4Ti alloy structure. Most of the effort on the tritium barrier coating development is focused on Al2O3 coatings formed on aluminized ferritic steels. This paper presents an overview of the status of coating development for the various fusion concepts with emphasis on the materials interaction and chemistry control issues associated with the formation, stability and performance of the coatings

    Large (>6 microm) rigid microparticles (MPs) become passively entrapped within the lungs after intravenous (i.v.) injection making them an attractive and highly efficient alternative to inhalation for pulmonary delivery. In this study, PEGylated 6 microm polystyrene MPs with multiple copies of the norvaline (Nva) alpha-amino acid prodrug of camptothecin (CPT) were prepared. Surface morphology was characterized using a scanning electron microscope. CPT was released from the CPT-Nva-MPs over 24 h in rat plasma at 37 degrees C. In-vivo CPT plasma concentrations were low (approximately 1 ng/ml or less) and constant over a period of 4 days after a single i.v. injection of CPT-Nva-MPs as compared with high but short-lived systemic exposures after an i.v. injection of free CPT. This suggests that sustained local CPT concentrations were achieved in the lung after administration of the MP delivery system. Anticancer efficacy was evaluated in an orthotopic lung cancer animal model and compared with a bolus injection of CPT. Animals receiving free CPT (2 mg/kg) and CPT-Nva-MPs (0.22 mg/kg CPT and 100 mg/kg MPs) were found to have statistically significant smaller areas of lung cancer (PNva-MPs were found to be free of cancer. The CPT dose using targeted MPs was 10 times lower than after i.v. injection of free CPT, but was more effective in reducing the amount of cancerous areas. In conclusion, CPT-Nva-MPs were able to achieve effective local lung and low systemic CPT concentrations at a dose that was 10 times lower than systemically administered CPT resulting in a significant improvement in anticancer efficacy in an orthotopic rat model of lung cancer.

    In 2009 May, the National Research Universal (NRU) calandria leaked. During the next year, the calandria was inspected with six new Non-Destructive Evaluation (NDE) techniques to determine the extent of the corrosion, repaired, and finally the repair was inspected with four additional new NDE techniques before the reactor was returned to service. The calandria is surrounded by a light-water reflector vessel fabricated from the same material as the calandria vessel. Concerns that the same corrosion mechanism had damaged the reflector vessel led to the development of a system to inspect the full circumference of the reflector wall for corrosion damage. The inspection region could only be accessed through 64 mm diameter ports, was 10 m below the port, and had to be inspected from the corroded surface. The ultrasonic technique was designed to produce a closely spaced wall thickness (WT) grid over an area of approximately 5 m2 on the corroded surface using a very small probe holder. This paper describes the Reflector Wall Inspection (RWI) development project and the system that resulted. (author)

  2. Mobile Systems Development: An Empirical Study

    DEFF Research Database (Denmark)

    Hosbond, J. H.

    As part of an ongoing study on mobile systems development (MSD), this paper presents preliminary findings of research-in-progress. The debate on mobility in research has so far been dominated by mobile HCI, technological innovations, and socio-technical issues related to new and emerging mobile work patterns. This paper is about the development of mobile systems.Based on an on-going empirical study I present four case studies of companies each with different products or services to offer and diverging ways of establishing and sustaining a successful business in the mobile industry. From the case studies I propose a five-layered framework for understanding the structure and segmentation of the industry. This leads to an analysis of the different modes of operation within the mobile industry, exemplified by the four case studies.The contribution of this paper is therefore two-fold: (1) I present preliminary findings from an on-going multiple case study that indicates and support a five-layered segmentation of the mobile industry, and (2) I propose four modes of operation reflecting the diversified nature of MSD.

  3. Development of a versatile digital readout system

    International Nuclear Information System (INIS)

    During the research and design phase of new detector electronics, development of a suitable test environment takes a significant amount of time. Most existing systems are specifically designed for certain frontend electronics and cannot be reused for future developments. Thus, our approach is to build a flexible test environment with state-of-the-art hardware, which can be reconfigured to support various frontend electronics. This is achieved by deploying a modular design concept, which is followed in both hardware and software. Key features of the hardware platform are the gigabit optical connection to the PC, the powerful FPGA (Virtex 4), and consequent separation of analog and digital parts of the readout. Via firmware updates, arbitrary communication protocols can be implemented and the external connectors of the readout board can be freely configured. This is accompanied by a modular software framework written in C++ which declares different communication layers for easy hardware access as well as a generic storage structure for simple data handling. These levels of abstraction make it easy to add support for changed or completely new devices. The implementation of the digital readout system as well as its modular firmware and software design is presented and its key features are explained in detail.

  4. Development of CANDU Spent Fuel Sipping System

    International Nuclear Information System (INIS)

    As the tendency is toward radioactivity zero-leakage on the reactor core for the safe operation of nuclear power plants, the importance of detecting radioactivity leaking from fuel assemblies irradiated in the core is being on the rise. Nuclear fuel, even though it is designed and fabricated in terms of excellent thermal performance and mechanical integrity, can be damaged under unexpected circumstances. An excessive hydriding on fuel rods and pellet-to-clad interaction., etc. can result in failed fuel rod. It is, thus, considered that a inspection process is prerequisite procedure to identify causes of such failed fuel rods for the safe operation of nuclear power plants. If a fuel rod failure occurs during the operation of a nuclear power plant, the coolant water becomes contaminated by leaked fission products, and the power level of the plant has to be lowered or the operation to be stopped. In addition, the spent fuel that have been stored in a spent fuel storage pool for a long time is now transferring to a dry storage. To maximize the integrity of the dry storage, all the fuels transferring to a dry storage should be examined their integrities exactly and efficiently. Therefore, the ultimate purpose of this study is to develop a system capable of judging whether the long-term stored fuel in spent fuel storage pool is failed or not. In this study, a spent fuel sipping system with wet leakage detection technology is developed to make it possible

  5. Development of tritium cleanup system for LHD

    International Nuclear Information System (INIS)

    Energy is vital for humans and we have been consuming a large amount of fossil fuel especially from the beginning of the industrial revolution. Nowadays its huge consumption has however come to threaten our life and we have to prepare nonfossil fuels, for instance solar energy, biomass energy, nuclear energy and so on. Fusion energy is an unlimited resource and one of the strongest candidates of the future energy source. At the National Institute for Fusion Science (referred to as 'NIFS' hereafter), we have constructed a new fusion experimental device called large helical device (referred to as 'LHD' hereafter) in 1998. The device will generate a small amount of tritium, as a fusion product. In order to remove it from the exhaust gas, we have designed a tritium cleanup system based on a new concept. This system is mainly composed of a palladium permeater, a decomposer and hydrogen absorbing alloys. It may perfectly recover the tritium from exhaust gas without oxidizing it. This system is applicable for the future needs at fusion power plants. In order to remove tritium discharged from fusion experimental facilities, it is usual to employ a system by which tritiated constituents, in various chemical forms, are entirely converted to a form of water vapor by catalytic oxidation. The water vapor containing tritiated form is then absorbed by molecular sieve (referred to as 'wet system' hereafter). However, in the case of LHD, it is not rational to deliberately convert the discharged tritium into the water vapor, because the tritium discharged from LHD is almost in a form of hydrogen molecules. Moreover, the tritium in the form of water vapor affects the human body 18000 times stronger than that of hydrogen molecules. In accordance with these view points, we have developed another type of tritium cleanup system based on a new concept, in which hydrogen molecules including tritiated ones (HT, DT and T2) found in the exhaust gas of LHD are directly fixed to hydrogen absorbing alloys. Other impurities such as methane and water vapor, parts of which are tritiated, will be decomposed into each elemental form by the decomposition process and hydrogen molecules, including tritiated constituents from the decomposition (referred to as 'dry system' hereafter)

    The sta:us of development of a Direct Drive Ha!! Thruster System is presented. 13 the first part. a s:udy of the impacts to spacecraft systems and mass benefits of a direct-drive architecture is reviewed. The study initially examines four cases of SPT-100 and BPT-4000 Hall thrusters used for north-south station keeping on an EXPRESS-like geosynchronous spacecraft and for primary propulsion for a Deep Space- 1 based science spacecraft. The study is also extended the impact of direct drive on orbit raising for higher power geosynchronous spacecraft and on other deep space missions as a function of power and delta velocity. The major system considerations for accommodating a direct drive Hall thruster are discussed, including array regulation, system grounding, distribution of power to the spacecraft bus, and interactions between current-voltage characteristics for the arrays and thrusters. The mass benefit analysis shows that, for the initial cases, up to 42 kg of dry mass savings is attributable directly to changes in the propulsion hardware. When projected mass impacts of operating the arrays and the electric power system at 300V are included, up to 63 kg is saved for the four initial cases. Adoption of high voltage lithium ion battery technology is projected to further improve these savings. Orbit raising of higher powered geosynchronous spacecraft, is the mission for which direct drive provides the most benefit, allowing higher efficiency electric orbit raising to be accomplished in a limited period of time, as well as nearly eliminating significant power processing heat rejection mass. The total increase in useful payload to orbit ranges up to 278 kg for a 25 kW spacecraft, launched from an Atlas IIA. For deep space missions, direct drive is found to be most applicable to higher power missions with delta velocities up to several km/s , typical of several Discovery-class missions. In the second part, the status of development of direct drive propulsion power electronics is presented. The core of this hardware is the heater-keeper-magnet supply being qualified for the BPT-4000 by Aerojet. A breadboard propulsion power unit is in fabrication and is scheduled for delivery late in 2003.

  7. Latvian natural gas system and its development

    International Nuclear Information System (INIS)

    The data presented in the paper evidence that natural gas consumption decreased from 2.91 billion m3 in 1991 to 0.95 in 1994, while in the period 1997-1999 it was levelled at about 1.3 billion m3. It is expected that there will be a gradual increase in natural gas consumption from 1.32 billion m:3 in 2001 to 1.95 billion m3 in 2005 mainly due to to development of co-generation stations and significant growth in the industrial sector. All the gas consumed in Latvia is imported from Russia during the summer period and injected into the Incukalns Underground Gas Storage for winter needs, in particular, for Latvian consumers as well as, partly, for Estonia and North-West of Russia. Latvia processes unique geological conditions for creation of a system of natural underground gas storage in the future with an active total volume of up to 50 billion m3. By integration of the Latvian underground gas storage system in the joint Russian - European gas transmission system, Latvia could become a major seasonal regulator of natural gas for Western regions of Russia and for Baltic Sea countries: Lithuania, Estonia, Finland, and Sweden.

    We describe some of the challenging aspects in the indigenous development of the whole head multichannel magnetoencephalography (MEG) system at IGCAR, Kalpakkam. These are: i) fabrication and testing of a helmet shaped sensor array holder of a polymeric material experimentally tested to be compatible with liquid helium temperatures, ii) the design and fabrication of the PCB adapter modules, keeping in mind the inter-track cross talk considerations between the electrical leads used to provide connections from SQUID at liquid helium temperature (4.2K) to the electronics at room temperature (300K) and iii) use of high resistance manganin wires for the 86 channels (86×8 leads) essential to reduce the total heat leak which, however, inevitably causes an attenuation of the SQUID output signal due to voltage drop in the leads. We have presently populated 22 of the 86 channels, which include 6 reference channels to reject the common mode noise. The whole head MEG system to cover all the lobes of the brain will be progressively assembled when other three PCB adapter modules, presently under fabrication, become available. The MEG system will be used for a variety of basic and clinical studies including localization of epileptic foci during pre-surgical mapping in collaboration with neurologists.

  9. Power Systems Development Facility. Environmental Assessment

    Energy Technology Data Exchange (ETDEWEB)

    1993-06-01

    The objective of the PSDF would be to provide a modular facility which would support the development of advanced, pilot-scale, coal-based power systems and hot gas clean-up components. These pilot-scale components would be designed to be large enough so that the results can be related and projected to commercial systems. The facility would use a modular approach to enhance the flexibility and capability for testing; consequently, overall capital and operating costs when compared with stand-alone facilities would be reduced by sharing resources common to different modules. The facility would identify and resolve technical barrier, as well as-provide a structure for long-term testing and performance assessment. It is also intended that the facility would evaluate the operational and performance characteristics of the advanced power systems with both bituminous and subbituminous coals. Five technology-based experimental modules are proposed for the PSDF: (1) an advanced gasifier module, (2) a fuel cell test module, (3) a PFBC module, (4) a combustion gas turbine module, and (5) a module comprised of five hot gas cleanup particulate control devices. The final module, the PCD, would capture coal-derived ash and particles from both the PFBC and advanced gasifier gas streams to provide for overall particulate emission control, as well as to protect the combustion turbine and the fuel cell.

  10. Development of CANDU core monitoring system

    International Nuclear Information System (INIS)

    The research was performed to develop a CANDU Core Monitoring System(CCMS) that enables operators to have efficient core management by monitoring core power distribution, burnup distribution, and the other important core variables and managing the past core history for Wolsong Nuclear Power Plant(NPP) No. 1. CCMS uses RFSP(Reactor Fueling Simulation Program) for continuous core calculation by integrating the algorithm and assumptions validated and uses the information taken from DCC(Digital Control Computer) for the purpose of producing basic input data. CCMS could be largely divided into two modules; CCMS server program and CCMS client program. CCMS server program plays the role in automatic and continuous RFSP run and management of the past output data resulting from the run using Data Base Management System(DBMS). CCMS client program enables users to monitor current and past core status with GUI(Graphic-User Interface) environment predefined. The effectiveness of CCMS was verified by comparing the data resulted from field-test of the system for about 43 hours with the data used in the field of Wolsong NPP No. 1

  11. Web-based Core Design System Development

    International Nuclear Information System (INIS)

    The selection of a loading pattern is one of core design processes in the operation of a nuclear power plant. A potential new loading pattern is identified by selecting fuels that to not exceed the major limiting factors of the design and that satisfy the core design conditions for employing fuel data from the existing loading pattern of the current operating cycle. The selection of a loading pattern is also related to the cycle plan of an operating nuclear power plant and must meet safety and economic requirements. In selecting an appropriate loading pattern, all aspects, such as input creation, code runs and result processes are processed as text forms manually by a designer, all of which may be subject to human error, such as syntax or running errors. Time-consuming results analysis and decision-making processes are the most significant inefficiencies to avoid. A web-based nuclear plant core design system was developed here to remedy the shortcomings of an existing core design system. The proposed system adopts the general methodology of OPR1000 (Korea Standard Nuclear Power Plants) and Westinghouse-type plants. Additionally, it offers a GUI (Graphic User Interface)-based core design environment with a user-friendly interface for operators. It reduces human errors related to design model creation, computation, final reload core model selection, final output confirmation, and result data validation and verification. Most significantly, it reduces the core design time by more than 75% compared to its predecessor

  12. Development of the environmental data management system

    International Nuclear Information System (INIS)

    The recent society requires business activities with environmental consideration to every enterprise. Also, Japanese laws require those activities. For example, 'Law Concerning the Promotion of Business Activities with Environmental Consideration by Specified Corporations, etc, by Facilitating Access to Environmental Information, and Other Measures' (Environmental Consideration Law) mandates publication of a report relating to the activities of environmental consideration to each enterprise above designated size. 'Act on the Rational Use of Energy' mandates the report of the results of energy consumption and the long-term plan of the rational use of energy. Moreover, 'Act on Promotion of Global Warming Countermeasures' mandates the report of the greenhouse gas emissions. In addition to those, 'Water Pollution Control Law', 'Waste Management and Public Cleaning Law' and other environmental laws as well as environmental ordinances require business activities with environmental consideration to all companies. So, it is very important for Japan Atomic Energy Agency (JAEA) to report business activities with environmental consideration in order to build up trustful relations with the nation and communities. The Environmental Data Management System has been developed as the data base of business activities with environmental consideration in JAEA and as the means to promote the activities at every site and office of JAEA. This report summarizes the structure of the Environmental Data Management System, kinds of environmental performance data treated by the system, and gathering methods of the data. (author)

    In this study, the effect of time fractionalization on the development of quantum systems is taken under consideration by making use of fractional calculus. In this context, a Mittag-Leffler function is introduced as an important mathematical tool in the generalization of the evolution operator. In order to investigate the time fractional evolution of the quantum (nano) systems, time fractional forms of motion are obtained for a Schrödinger equation and a Heisenberg equation. As an application of the concomitant formalism, the wave functions, energy eigenvalues, and probability densities of the potential well and harmonic oscillator are time fractionally obtained via the fractional derivative order α, which is a measure of the fractality of time. In the case α =1, where time becomes homogenous and continuous, traditional physical conclusions are recovered. Since energy and time are conjugate to each other, the fractional derivative order α is relevant to time. It is understood that the fractionalization of time gives rise to energy fluctuations of the quantum (nano) systems.

    Environmental neutron detection system is proposed. The main goal of this system was set to detect fast and thermal neutrons with the identical detector setup without degraders. A detector setup for the system with a sup 1 sup 0 B doped liquid scintillator, which had been optimized for thermal neutron counting in last year, was developed first. For optimization of for fast neutron counting, density of sup 1 sup 0 B and the size of the detector were fixed by measurement of fast neutrons, with help of the Monte Carlo calculation. In the meantime, possibility of the use of inorganic scintillators in neutron counting were verified, to solve the problem occurring at the long term use of the organic liquid scintillators. The detectors checked were LSO, BaF sub 2 , BGO and GSO. LSO and BaF sub 2 have much more difficulties in neutron counting such as background counting rates and BGO has some unclear signals at neutron measurements. GSO was shown to be the most probable candidate among them at the measurement of neu...

    2013-01-01

    A concept for a Universal Waste Management System (UWMS) has been developed based on the knowledge gained from over 50 years of space travel. It is being designed for Commercial Orbital Transportation Services (COTS) and Multi ]Purpose Crew Vehicle (MPCV) and is based upon the Extended Duration Orbiter (EDO) commode. The UMWS was modified to enhance crew interface and reduce volume and cost. The UWMS will stow waste in fecal canisters, similar to the EDO, and urine will be stowed in bags for in orbit change out. This allows the pretreated urine to be subsequently processed and recovered as drinking water. The new design combines two fans and a rotary phase separator on a common shaft to allow operation by a single motor. This change enhances packaging by reducing the volume associated with an extra motor, associated controller, harness, and supporting structure. The separator pumps urine to either a dual bag design for COTS vehicles or directly into a water reclamation system. The commode is supported by a concentric frame, enhancing its structural integrity while further reducing the volume from the previous design. The UWMS flight concept development effort is underway and an early output of the development will be a ground based UMWS prototype for manned testing. Referred to as the Gen 3 unit, this prototype will emulate the crew interface included in the UWMS and will offer a great deal of knowledge regarding the usability of the new design, allowing the design team the opportunity to modify the UWMS flight concept based on the manned testing.

    As a subcontractor to General Motors (GM), Ames Laboratory provided the technical expertise and supplied experimental materials needed to assess the technology of high energy bonded permanent magnets that are injection or compression molded for use in the Advanced Electric Traction System motor. This support was a sustained (Phase 1: 6/07 to 3/08) engineering effort that builds on the research achievements of the primary FreedomCAR project at Ames Laboratory on development of high temperature magnet alloy particulate in both flake and spherical powder forms. Ames Lab also provide guidance and direction in selection of magnet materials and supported the fabrication of experimental magnet materials for development of injection molding and magnetization processes by Arnold Magnetics, another project partner. The work with Arnold Magnetics involved a close collaboration on particulate material design and processing to achieve enhanced particulate properties and magnetic performance in the resulting bonded magnets. The overall project direction was provided by GM Program Management and two design reviews were held at GM-ATC in Torrance, CA. Ames Lab utilized current expertise in magnet powder alloy design and processing, along with on-going research advances being achieved under the existing FreedomCAR Program project to help guide and direct work during Phase 1 for the Advanced Electric Traction System Technology Development Program. The technical tasks included review of previous GM and Arnold Magnets work and identification of improvements to the benchmark magnet material, Magnequench MQP-14-12. Other benchmark characteristics of the desired magnet material include 64% volumetric loading with PPS polymer and a recommended maximum use temperature of 200C. A collaborative relationship was maintained with Arnold Magnets on the specification and processing of the bonded magnet material required by GM-ATC.

  18. Development of Shimadzu digital subtraction system

    International Nuclear Information System (INIS)

    Shimadzu has recently developed a digital subtraction system. It can perform intra-arterial digital subtraction angiography (DSA) using low concentration of contrast medium, or can visualize arteries with intravenuous injection. It can extremely reduce patient's pain in angiography. Image quality of DSA has been much improved by the development of high quality image amplifiers, improvement of signal-to-noise ratio of the x-ray television unit and the development of digital disk recorders. The peak-hold subtraction method that is now under clinical study presents images of blood vessels as the trace of the flow of contrast medium. The maximum-hold memory where the maximum value of the brightness in some period is stored for every picture element is subtracted from the minimum-hold memory where the minimum value is stored, and thus images of blood vessels can be obtained. Hardware of this method is rather simple and it is expected that the amount of contrast medium may be reduced or x-ray dose of the patient may be decreased. (author)

    Solar approached Phase II of ATS program with the goal of 50% thermal efficiency. An intercolled and recuperated gas turbine was identified as the ultimate system to meet this goal in a commercial gas turbine environment. With commercial input from detailed market studies and DOE`s ATS program, Solar redefined the company`s proposed ATS to fit both market and sponsor (DOE) requirements. Resulting optimized recuperated gas turbine will be developed in two sizes, 5 and 15 MWe. It will show a thermal efficiency of about 43%, a 23% improvement over current industrial gas turbines. Other ATS goals--emissions, RAMD (reliability, availability, maintainability, durability), cost of power--will be met or exceeded. During FY95, advanced development of key materials, combustion and component technologies proceeded to the point of acceptance for inclusion in ATS Phase III.

  20. Development of novel emission tomography system

    Science.gov (United States)

    Fu, Geng

    In recent years, small animals, such as mice and rats, have been widely used as subjects of study in biomedical research while molecular biology and imaging techniques open new opportunities to investigate disease model. With the help of medical imaging techniques, researchers can investigate underlying mechanisms inside the small animal, which are useful for both early diagnosis and treatment monitoring. Based on tracer principle single photon emission computed tomography (SPECT) has increased popularity in small animal imaging due to its higher spatial resolution and variety of single-photon emitting radionuclides. Since the image quality strongly depends on the detector properties, both scintillation and semiconductor detectors are under active investigation for high resolution X-ray and gamma ray photon detection. The desired detector properties include high intrinsic spatial resolution, high energy resolution, and high detection efficiency. In this thesis study, we have made extensive efforts to develop novel emission tomography system, and evaluate the use of both semiconductor and ultra-high resolution scintillation detectors for small animal imaging. This thesis work includes the following three areas. Firstly, we have developed a novel energy-resolved photon counting (ERPC) detector. With the benefits of high energy resolution, high spatial resolution, flexible detection area, and a wide dynamic range of 27--200keV, ERPC detector is well-suited for small animal SPECT applications. For prototype ERPC detector excellent imaging (˜350microm) and spectroscopic performance (4keV Co-57 122keV) has been demonstrated in preliminary study. Secondly, to further improve spatial resolution to hundred-micron level, an ultra-high resolution Intensified EMCCD (I-EMCCD) detector has been designed and evaluated. This detector consists of the newly developed electron multiplying CCD (EMCCD) sensor, columnar CsI(Tl) scintillator, and an electrostatic de-magnifier (DM) tube. The detector offers the combination of an excellent intrinsic spatial resolution, a good signal-to-noise ratio (SNR), a large active area, and reasonable detection efficiency over the energy range from 27 to 140 keV. Based on I-EMCCD detector we developed a prototype dual-head single photon emission microscope (SPEM) system for mouse imaging. Both phantom and animal imaging experiments have been performed to evaluate system capabilities for ultra-high resolution SPECT imaging. In addition, we have presented a feasibility study of using emission tomography system for synchrotron X-ray fluorescence computer tomography (XFCT). Based on high resolution semiconductor detector and collimation aperture, X-ray fluorescence emission tomography (XFET) can offer more imaging information content by each detected photon and allow less scanning motion, which help to overcome the hurdle for current X-ray fluorescence computed tomography (XFCT) and improve imaging speed. CCD-based emission tomography system has been set up at the Advanced Photon Source (APS) for phantom and animal imaging. It has demonstrated that XFET is capable of acquiring 3D element distribution with a greatly improved imaging speed. Key words: SPECT, ERPC, I-EMCCD, SPEM, APS, and XFET

    The VCS (Vertical Cable Seismic) is one of the reflection seismic methods. It uses hydrophone arrays vertically moored from the seafloor to record acoustic waves generated by surface, deep-towed or ocean bottom sources. Analyzing the reflections from the sub-seabed, we could look into the subsurface structure. Because VCS is an efficient high-resolution 3D seismic survey method for a spatially-bounded area, we proposed the method for the hydrothermal deposit survey tool development program that the Ministry of Education, Culture, Sports, Science and Technology (MEXT) started in 2009. We are now developing a VCS system, including not only data acquisition hardware but data processing and analysis technique. We carried out several VCS surveys combining with surface towed source, deep towed source and ocean bottom source. The water depths of the survey are from 100m up to 2100m. The target of the survey includes not only hydrothermal deposit but oil and gas exploration. Through these experiments, our VCS data acquisition system has been completed. But the data processing techniques are still on the way. One of the most critical issues is the positioning in the water. The uncertainty in the positions of the source and of the hydrophones in water degraded the quality of subsurface image. GPS navigation system are available on sea surface, but in case of deep-towed source or ocean bottom source, the accuracy of shot position with SSBL/USBL is not sufficient for the very high-resolution imaging. We have developed another approach to determine the positions in water using the travel time data from the source to VCS hydrophones. In the data acquisition stage, we estimate the position of VCS location with slant ranging method from the sea surface. The deep-towed source or ocean bottom source is estimated by SSBL/USBL. The water velocity profile is measured by XCTD. After the data acquisition, we pick the first break times of the VCS recorded data. The estimated positions of shot points and receiver points in the field include the errors. We use these data as initial guesses, we invert iteratively shot and receiver positions to match the travel time data. After several iterations we could finally estimate the most probable positions. Integration of the constraint of VCS hydrophone positions, such as the spacing is 10m, can accelerate the convergence of the iterative inversion and improve results. The accuracy of the estimated positions from the travel time date is enough for the VCS data processing.

    In 2009, Ministry of Education, Culture, Sports, Science and Technology(MEXT) started the survey system development for Hydrothermal deposit. We proposed the Vertical Cable Seismic (VCS), the reflection seismic survey with vertical cable above seabottom. VCS has the following advantages for hydrothermal deposit survey. (1) VCS is an efficient high-resolution 3D seismic survey in limited area. (2) It achieves high-resolution image because the sensors are closely located to the target. (3) It avoids the coupling problems between sensor and seabottom that cause serious damage of seismic data quality. (4) Because of autonomous recording system on sea floor, various types of marine source are applicable with VCS such as sea-surface source (GI gun etc.) , deep-towed or ocean bottom source. Our first experiment of 2D/3D VCS surveys has been carried out in Lake Biwa, JAPAN, in November 2009. The 2D VCS data processing follows the walk-away VSP, including wave field separation and depth migration. Seismic Interferometry technique is also applied. The results give much clearer image than the conventional surface seismic. Prestack depth migration is applied to 3D data to obtain good quality 3D depth volume. Seismic Interferometry technique is applied to obtain the high resolution image in the very shallow zone. Based on the feasibility study, we have developed the autonomous recording VCS system and carried out the trial experiment in actual ocean at the water depth of about 400m to establish the procedures of deployment/recovery and to examine the VC position or fluctuation at seabottom. The result shows that the VC position is estimated with sufficient accuracy and very little fluctuation is observed. Institute of Industrial Science, the University of Tokyo took the research cruise NT11-02 on JAMSTEC R/V Natsushima in February, 2011. In the cruise NT11-02, JGI carried out the second VCS survey using the autonomous VCS recording system with the deep towed source provided by Institute of Industrial Science, the University of Tokyo. It generates high frequency acoustic waves around 1kHz. The acquired VCS data clearly shows the reflections and currently being processed for imaging the subsurface structure.

    The Facilities Engineering and Architectural Branch is responsible for the design and maintenance of buildings, laboratories, and civil structures. In order to improve efficiency and quality, the FEAB has dedicated itself to establishing a data infrastructure based on Geographic Information Systems, GIs. The value of GIS was explained in an article dating back to 1980 entitled "Need for a Multipurpose Cadastre which stated, "There is a critical need for a better land-information system in the United States to improve land-conveyance procedures, furnish a basis for equitable taxation, and provide much-needed information for resource management and environmental planning." Scientists and engineers both point to GIS as the solution. What is GIS? According to most text books, Geographic Information Systems is a class of software that stores, manages, and analyzes mapable features on, above, or below the surface of the earth. GIS software is basically database management software to the management of spatial data and information. Simply put, Geographic Information Systems manage, analyze, chart, graph, and map spatial information. At the outset, I was given goals and expectations from my branch and from my mentor with regards to the further implementation of GIs. Those goals are as follows: (1) Continue the development of GIS for the underground structures. (2) Extract and export annotated data from AutoCAD drawing files and construct a database (to serve as a prototype for future work). (3) Examine existing underground record drawings to determine existing and non-existing underground tanks. Once this data was collected and analyzed, I set out on the task of creating a user-friendly database that could be assessed by all members of the branch. It was important that the database be built using programs that most employees already possess, ruling out most AutoCAD-based viewers. Therefore, I set out to create an Access database that translated onto the web using Internet Explorer as the foundation. After some programming, it was possible to view AutoCAD files and other GIS-related applications on Internet Explorer, while providing the user with a variety of editing commands and setting options. I was also given the task of launching a divisional website using Macromedia Flash and other web- development programs.

  4. Development of CRD stub tube welding system

    International Nuclear Information System (INIS)

    The reactor pressure vessel (RPV) of nuclear power plants include control rod drive (CRD) stub tubes installed on the inner surface of the bottom head by welding. Weld seams are located at the root of each stub tube, to which accessibility is limited. The weld travel requires an elliptical movement with inclination along the inner bottom head surface, and furthermore the location on the bottom head of each stub tube has different angle of inclination. CRD stub tubes were installed by skilled welders using MIG welding in previous RPV construction. Recently, a CRD stub tube TIG welding system was developed for RPV construction in the near future, which can be applied to such 3 dimensional welding orbit. (author)

  5. The development of the JET electromagnetic system

    International Nuclear Information System (INIS)

    A series of enhancements of the JET apparatus is in the process of being implemented to increase the fusion parameter nsub(iD)Tsub(i)?sub(E) to values required for meaningful D-T operation. Modifications to the electromagnetic system (magnets, power supplies and plasma control) are major features of the new JET development plans, for operation with magnetic limiter up to 4MA and with material limiter up to 7MA. If the electromagnetic, thermal and mechanical assessment of the machine and power supplies, now underway, shows that the indicated extensions of the JET engineering operating space are possible, flat top currents of duration 10s and magnitude 4 and 7MA will be achieved in magnetic and material limiter configurations, respectively.

    The Controls software for the Large Hadron Collider (LHC) at CERN, with more than 150 millions lines of code, resides amongst the largest known code bases in the world1. Industry has been applying Agile software engineering techniques for more than two decades now, and the advantages of these techniques can no longer be ignored to manage the code base for large projects within the accelerator community. Furthermore, CERN is a particular environment due to the high personnel turnover and manpower limitations, where applying Agile processes can improve both, the codebase management as well as its quality. This paper presents the successful application of the Agile software development process Scrum for machine protection systems at CERN, the quality standards and infrastructure introduced together with the Agile process as well as the challenges encountered to adapt it to the CERN environment.

  8. Development of respiratory gating system in MRI

    International Nuclear Information System (INIS)

    Respiratory gating system in a 0.15 Tesla MRI was developed in order to reduce motion artifacts by respiration. As devices to detect-respiratory movement, we employed an air bag, a electrolyte band or a thermistor. The quality of respiratory gated images of the abdomen was much improved, especially by using the air bag or the band with a tube containing electrolyte solution. Respitatory gating improved the visualization of abdominal viscera such as liver, spleen, gallbladder and kidneys. Combination of respiratory and cardiac gating made the images much better. Respiratory gating tends to make the scan time longer, however, improvement of the image quality offsets the demerit enough and can save the averaging times. (author)

    Full Text Available Research on robot hand design is being carried out to accommodate a variety of tasks such as grasping and manipulation of objects in the field of industrial applications, service robots and rehabilitation robots. Problem statement: To design and develop a microcontroller-based four fingered robotic hand with a simple and minimal control strategy to pick and place application with object detection by simple IR sensor logic. Approach: The methodology is based on anthropomorphic design with three fingers and an opposing thumb. Each finger has three links and three double revolute joints. Each finger is actuated by a single opposing pair of tendons. The robot hand system is interfaced to microcontroller with software control by means of 14 independent commands for the motion of joints: close and open for fore finger, middle finger, ring finger and thumb finger and wrist up and down, base clockwise and counter clockwise, pick and place and home position. The tendoning system and wireless feedback logic provide the hand with the ability to confirm to object topology and therefore providing the advantage of using a simple control structure. Results: Reliable grasping and releasing is achieved with simple control mechanisms and IR sensors/push-button switches. The hand can pick a variety of objects with different surface characteristics and shapes without having to reconstruct its surface description. Picking of the object is successfully completed as long as the object is within the workspace of the hand and placed the object at the desired position within the workspace by relevant software control using keyboard commands. Conclusion: Hardware and software development of microcontroller-based four-fingered robotic hand is addressed. Details of hand control software for mainly pick and place applications are presented. Results of the experimental work for pick and place application of different objects is enumerated.

  10. The development of the JET electromagnetic system

    International Nuclear Information System (INIS)

    A series of enhancements of the JET apparatus is in the process of being implemented to increase the fusion parameter eta/sub iD/T/sub i/tau/sub E/ to values required for meaningful D - T operation. Modifications to the electromagnetic system (magnets, power supplies and plasma control) are major features of the new JET development plans, for operation with magnetic limiter up to 4MA and with material limiter up to 7MA. Operation at these levels, well above design values, requires compensation of stray fields at breakdown, control of plasma current derivative during the early phase of the discharge, larger currents in the primary windings of the transformer (coil I) and arrangements for establishing magnetic limiter configurations. To this end coil I will be made a 10 subcoil stack (now 8), a fast rise voltage shaping circuit and a DC power supply will be added to the present JET poloidal system, and the radial field control will be modified to cater for the magnetic limiter configuration with both one and two X-points. If the electromagnetic, thermal and mechanical assessment of the machine and power supplies, now underway, shows that the indicated extensions of the JET engineering operations space are possible, flat top current s of duration 10s and magnitude 4 and 7MA will be achieved in magnetic and material limiter configurations, respectively

    BAE Systems' SMART (Stacked Modular Architecture High-Resolution Thermal) Chip Camera provides very compact long-wave infrared (LWIR) solutions by combining a 12 μm wafer-level packaged focal plane array (FPA) with multichip-stack, application-specific integrated circuit (ASIC) and wafer-level optics. The key innovations that enabled this include a single-layer 12 μm pixel bolometer design and robust fabrication process, as well as wafer-level lid packaging. We used advanced packaging techniques to achieve an extremely small-form-factor camera, with a complete volume of 2.9 cm3 and a thermal core weight of 5.1g. The SMART Chip Camera supports up to 60 Hz frame rates, and requires less than 500 mW of power. This work has been supported by the Defense Advanced Research Projects Agency's (DARPA) Low Cost Thermal Imager - Manufacturing (LCTI-M) program, and BAE Systems' internal research and development investment.

  12. Systems approach to nuclear waste glass development

    International Nuclear Information System (INIS)

    Development of a host solid for the immobilization of nuclear waste has focused on various vitreous wasteforms. The systems approach requires that parameters affecting product performance and processing be considered simultaneously. Application of the systems approach indicates that borosilicate glasses are, overall, the most suitable glasses for the immobilization of nuclear waste. Phosphate glasses are highly durable; but the glass melts are highly corrosive and the glasses have poor thermal stability and low solubility for many waste components. High-silica glasses have good chemical durability, thermal stability, and mechanical stability, but the associated high melting temperatures increase volatilization of hazardous species in the waste. Borosilicate glasses are chemically durable and are stable both thermally and mechanically. The borosilicate melts are generally less corrosive than commercial glasses, and the melt temperature miimizes excessive volatility of hazardous species. Optimization of borosilicate waste glass formulations has led to their acceptance as the reference nuclear wasteform in the United States, United Kingdom, Belgium, Germany, France, Sweden, Switzerland, and Japan

  13. Information System on Occupational Exposure: Future Developments

    International Nuclear Information System (INIS)

    In response to pressures from deregulation and from ageing of the global nuclear power plant fleet, radiation protection personnel have found that occupational exposures are best managed through proper job planning, implementation and review to ensure that exposures are 'as low as reasonably achievable'(ALARA). A prerequisite for applying the principle of optimisation to occupational radiation protection is the timely exchange of data and information on dose reduction methods. To facilitate this global approach to work management, the OECD Nuclear Energy Agency (Nea) launched the Information System on Occupational Exposure (I.S.O.E.) in 1992. The objective of I.S.O.E. is to provide a forum for radiation protection experts from both utilities and national regulatory authorities to discuss, promote and coordinate international cooperative undertakings for the radiological protection of workers at nuclear power plants.The I.S.O.E. programme offers a variety of products in the occupational exposure area, such as: the world largest database on occupational exposure from nuclear power plants, a yearly analysis of dose trends and an overview of current developments, through I.S.O.E. Annual Reports, detailed studies, analyses, and information on current issues in operational radiation protection, through I.S.O.E. Information Sheets, a system for rapid communication of radiation protection-related information, such as effective dose reduction approaches and implementation of work management principles. A forum for discussing occupational exposure management issues through I.S.O.E. workshops, symposia and newsletters. (N.C.)

  14. Development of advanced reprocessing system 'FLUOREX'

    International Nuclear Information System (INIS)

    The nuclear fuel reprocessing technology 'FLUOREX' is a hybrid system that combines fluoride volatility and solvent extraction methods, where the major U in spent fuel is separated as UF6 gas efficiently by the fluoride volatility method and MOX is recovered by well-established conventional PUREX like process which, however, does not have uranium-plutonium partitioning part for strong proliferation resistance. The system can recover pure U and MOX with a decontamination factor of over 107 and can drastically reduce costs compared with the conventional one. From 2001 to 2004, we carried out the examination for the fundamental process of FLUOREX. The investigation have been continued from 2004 to 2007 from the viewpoint of the engineering of flame reactor control, the development of systems such as decladding, UF6 purification including the trace Pu recovery process using UO2F2 adsorbent, and the conversion of MOX resources, and the influence of fluorine on the dissolution and extraction processes. We concluded that from those experimental results, key processes of FLUOREX are fundamentally proved. From 2008 to 2010, we carried out the important investigation for advanced stage of UF6 purification, recovery of PuF6, conversion of fluoride FPs to oxide, and effect of fluorine on material in the solvent extraction process. The UF6 purification process was examined in the semi-engineering scale using a flame reactor and absorbent traps. We got the prospect for UF6 purification using fluoride absorbents such as NaF and MgF2. We studied recovery of PuF6 by UO2F2 absorbent in small apparatus using Pu, Np and Tc. The engineering scale test of oxide conversion demonstrated that the rotary kiln was applicable for conversion process of non-volatile fluoride FPs to oxides. Effect of fluorine on material in the solvent extraction was examined with corrosion test and electrochemical analysis. These results demonstrated the applicability of FLUOREX to new generation reprocessing. (author)

  15. Development of shielding design analysis system

    International Nuclear Information System (INIS)

    The aim of this work is to develop insufficient auxiliary routines which manage input and output data and interface the main codes and to establish a shielding design analysis system on work stations (SUN, DEC). In shielding design analyses, one- and two- dimensional (1-D and 2-D) transport Sn codes are used mainly with some auxiliary codes which generate input data of Sn calculation and edit Sn calculation outputs. The main transport calculation codes can be obtained from the Code Center of RIST (Research Organization for Information Science and Technology). In this work, peripheral codes are developed to generate cross sections, produce Sn quadrature sets, edit calculation outputs or draw contour figures. In shielding calculations around a reactor, the boot-strapping technique is often employed to treat a large area extending from the core to the biological shield to improve the calculation accuracy. When a three-dimensional (3-D) calculation for a complex geometry with shielding defects, 2-D and 3-D coupling calculation is employed frequently. To use this coupling method conversion cods are prepared which read flux file from DORT and prepare an external boundary source file for the 2-D or the 3-D calculation codes. For further conveniences well used data such as the Sn quadrature sets, the dose rate conversion factors, the reaction cross section sets are stored as a data base and code manuals including sample inputs of typical problems are prepared which are comprehensible to beginners.

  17. Development of the excretory system in a polyplacophoran mollusc: stages in metanephridial system development

    Baeumler Natalie

    2012-09-01

    Full Text Available Abstract Background Two types of excretory systems, protonephridia and metanephridial systems are common among bilaterians. The homology of protonephridia of lophotrochozoan taxa has been widely accepted. In contrast, the homology of metanephridial systems – including coelomic cavities as functional units – among taxa as well as the homology between the two excretory systems is a matter of ongoing discussion. This particularly concerns the molluscan kidneys, which are mostly regarded as being derived convergently to the metanephridia of e.g. annelids because of different ontogenetic origin. A reinvestigation of nephrogenesis in polyplacophorans, which carry many primitive traits within molluscs, could shed light on these questions. Results The metanephridial system of Lepidochitona corrugata develops rapidly in the early juvenile phase. It is formed from a coelomic anlage that soon achieves endothelial organization. The pericardium and heart are formed from the central portion of the anlage. The nephridial components are formed by outgrowth from lateral differentiations of the anlage. Simultaneously with formation of the heart, podocytes appear in the atrial wall of the pericardium. In addition, renopericardial ducts, kidneys and efferent nephroducts, all showing downstream ciliation towards the internal lumen, become differentiated (specimen length: 0.62 mm. Further development consists of elongation of the kidney and reinforcement of filtration and reabsorptive structures. Conclusions During development and in fully formed condition the metanephridial system of Lepidochitona corrugata shares many detailed traits (cellular and overall organization with the protonephridia of the same species. Accordingly, we suggest a serial homology of various cell types and between the two excretory systems and the organs as a whole. The formation of the metanephridial system varies significantly within Mollusca, thus the mode of formation cannot be used as a homology criterion. Because of similarities in overall organization, we conclude that the molluscan metanephridial system is homologous with that of the annelids not only at the cellular but also at the organ level.

  19. Controlling Complex Systems and Developing Dynamic Technology

    Science.gov (United States)

    Avizienis, Audrius Victor

    In complex systems, control and understanding become intertwined. Following Ilya Prigogine, we define complex systems as having control parameters which mediate transitions between distinct modes of dynamical behavior. From this perspective, determining the nature of control parameters and demonstrating the associated dynamical phase transitions are practically equivalent and fundamental to engaging with complexity. In the first part of this work, a control parameter is determined for a non-equilibrium electrochemical system by studying a transition in the morphology of structures produced by an electroless deposition reaction. Specifically, changing the size of copper posts used as the substrate for growing metallic silver structures by the reduction of Ag+ from solution under diffusion-limited reaction conditions causes a dynamical phase transition in the crystal growth process. For Cu posts with edge lengths on the order of one micron, local forces promoting anisotropic growth predominate, and the reaction produces interconnected networks of Ag nanowires. As the post size is increased above 10 microns, the local interfacial growth reaction dynamics couple with the macroscopic diffusion field, leading to spatially propagating instabilities in the electrochemical potential which induce periodic branching during crystal growth, producing dendritic deposits. This result is interesting both as an example of control and understanding in a complex system, and as a useful combination of top-down lithography with bottom-up electrochemical self-assembly. The second part of this work focuses on the technological development of devices fabricated using this non-equilibrium electrochemical process, towards a goal of integrating a complex network as a dynamic functional component in a neuromorphic computing device. Self-assembled networks of silver nanowires were reacted with sulfur to produce interfacial "atomic switches": silver-silver sulfide junctions, which exhibit complex dynamics (e.g. both short- and long-term changes in conductivity) in response to applied voltage signals. Characterization of these atomic switch networks (ASNs) brought out interesting parallels to biological neural networks, including power-law scaling in the statistics of electrical signal propagation and dynamic self-organization of differentiated subnetworks. A reservoir computing (RC) strategy was employed to utilize measurements of electrical signals dynamically generated in ASNs to perform time-series memory and manipulation tasks including a parity test and arbitrary waveform generation. These results represent the useful integration of a complex network into a dynamic physical RC device.

    2008-01-18

    Background: The Rosebud Sioux Tribe (RST) is located in south central South Dakota near the Nebraska border. The nearest community of size is Valentine, Nebraska. The RST is a recipient of several Department of Energy grants, written by Distributed Generation Systems, Inc. (Disgen), for the purposes of assessing the feasibility of its wind resource and subsequently to fund the development of the project. Disgen, as the contracting entity to the RST for this project, has completed all the pre-construction activities, with the exception of the power purchase agreement and interconnection agreement, to commence financing and construction of the project. The focus of this financing is to maximize the economic benefits to the RST while achieving commercially reasonable rates of return and fees for the other parties involved. Each of the development activities required and its status is discussed below. Land Resource: The Owl Feather War Bonnet 30 MW Wind Project is located on RST Tribal Trust Land of approximately 680 acres adjacent to the community of St. Francis, South Dakota. The RST Tribal Council has voted on several occasions for the development of this land for wind energy purposes, as has the District of St. Francis. Actual footprint of wind farm will be approx. 50 acres. Wind Resource Assessment: The wind data has been collected from the site since May 1, 2001 and continues to be collected and analyzed. The latest projections indicate a net capacity factor of 42% at a hub height of 80 meters. The data has been collected utilizing an NRG 9300 Data logger System with instrumentation installed at 30, 40 and 65 meters on an existing KINI radio tower. The long-term annual average wind speed at 65-meters above ground level is 18.2 mph (8.1 mps) and 18.7 mph (8.4 mps) at 80-meters agl. The wind resource is excellent and supports project financing.
