MPS II drift chamber system  

Energy Technology Data Exchange (ETDEWEB)

The MPS II detectors are narrow drift space chambers designed for high position resolution in a magnetic field and in a very high particle flux environment. Central to this implementation was the development of 3 multi-channel custom IC's and one multi-channel hybrid. The system is deadtimeless and requires no corrections on an anode-to-anode basis. Operational experience and relevance to ISABELLE detectors is discussed.

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. copyright 1997 American Institute of Physics

Characteristics of the new MPS II spectrometer system  

Energy Technology Data Exchange (ETDEWEB)

The BNL MPS II is a conversion of the spark chamber detector system of MPS I to a narrow drift space novel drift chamber system. A description is given of this very compact drift chamber system in which the electronics for individual channels is mounted on the chamber. Under actual experimental operating conditions, the chamber shows high resolution of approx. = 200 microns, are dead-time free, and yielded excellent performance. The digital electronics used eliminates channel-by-channel corrections. We have used it in a very large drift chamber system for which it is well suited since it requires less than one integrated circuit per channel. A description of the system, its testing, its use and results obtained in an experiment is presented and discussed.

MPS II: adaptive behavior of patients and impact on the family system.  

Science.gov (United States)

Mucopolysaccharidosis type II (MPS II), also known as Hunter syndrome, is a chronic and progressive X-linked lysosomal disease that mainly affects males. It occurs in 1 in every 65,000 to 1 in 132,000 births. There are two distinct forms of the disease based on age of onset and clinical course: mild and severe. MPS II affects many organ systems including the nervous, cardiovascular, gastrointestinal and respiratory systems. Complications can include vision problems, progressive hearing loss, thickened and elastic skin, mental impairment, and enlarged liver and spleen. We herein focus on the adaptive behavior of individuals with MPS II, and the impact of MPS II on the family system. Outcomes from the Vineland-II Adaptive Behavior Scales showed that the MPS II patient sample experienced significantly lower functioning in communication, daily living skills, socialization, and motor skills compared to normative data. Patients with severe MPS II were found to have significantly lower adaptive functioning in all domains, as compared to those with mild MPS II. Length of time on ERT had no significant relationship to adaptive functioning. Results from the Peds QL Family Impact Module indicated that families of patients with MPS II experienced a lower overall health-related quality of life and overall lower family functioning (including lower emotional and cognitive functioning) than those with chronic illnesses residing in an inpatient setting.

The MPS II - A tracking detector system for large high rate experiments  

International Nuclear Information System (INIS)

The MPS II tracking detector system was developed for a variety of low cross section experiments that are only practical in a high beam rate environment. It was built as a general purpose device for use in a fixed target (AGS) situation where the beam passes through all elements of the detector. The electronics is dead-timeless so that high efficiency is achieved at event rates as high as 10/sup 6//sec/ch. This capability would allow these detectors to be used as close as 20 cm from a hadron-hadron collider at 1 Tev luminosity up to 10/sup 33//cm/sup 2/sec

MPS Editor  

Science.gov (United States)

Previously, it was time-consuming to hand-edit data and then set up simulation runs to find the effect and impact of the input data on a spacecraft. MPS Editor provides the user the capability to create/edit/update models and sequences, and immediately try them out using what appears to the user as one piece of software. MPS Editor provides an integrated sequencing environment for users. It provides them with software that can be utilized during development as well as actual operations. In addition, it provides them with a single, consistent, user friendly interface. MPS Editor uses the Eclipse Rich Client Platform to provide an environment that can be tailored to specific missions. It provides the capability to create and edit, and includes an Activity Dictionary to build the simulation spacecraft models, build and edit sequences of commands, and model the effects of those commands on the spacecraft. MPS Editor is written in Java using the Eclipse Rich Client Platform. It is currently built with four perspectives: the Activity Dictionary Perspective, the Project Adaptation Perspective, the Sequence Building Perspective, and the Sequence Modeling Perspective. Each perspective performs a given task. If a mission doesn't require that task, the unneeded perspective is not added to that project's delivery. In the Activity Dictionary Perspective, the user builds the project-specific activities, observations, calibrations, etc. Typically, this is used during the development phases of the mission, although it can be used later to make changes and updates to the Project Activity Dictionary. In the Adaptation Perspective, the user creates the spacecraft models such as power, data store, etc. Again, this is typically used during development, but will be used to update or add models of the spacecraft. The Sequence Building Perspective allows the user to create a sequence of activities or commands that go to the spacecraft. It provides a simulation of the activities and commands that have been created.

DET/MPS - THE GSFC ENERGY BALANCE PROGRAM, DIRECT ENERGY TRANSFER/MULTIMISSION SPACECRAFT MODULAR POWER SYSTEM (UNIX VERSION)  

Science.gov (United States)

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.

FEDERAL USERS CONFERENCE PRODUCT LINE TOOL SET (PLTS) MAP PRODUCTION SYSTEM (MPS) ATLAS CUSTOM GRIDS [Rev 0 was draft  

International Nuclear Information System (INIS)

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

Development of a Lagrangian Meshless Flow Solver based on the Moving Particle Semi-implicit (MPS) Method  

Science.gov (United States)

This paper discusses on the development of a meshless flow solver based on the Lagrangian particle method. The differential operators are discretised by using the particle interaction models proposed in the numerical framework of the Moving Particle Semi-implicit (MPS) technique. The MPS method is attractive from the viewpoint of no mesh is required and fluid is purely represented by points (the virtue of meshless algorithm). Some flow applications attempted by the current meshless solver will be shown and results are compared with the published experimental data.

Highly concentrated toluene decomposition on the dielectric barrier discharge (DBD) plasma-photocatalytic hybrid system with Mn-Ti-incorporated mesoporous silicate photocatalyst (Mn-Ti-MPS)  

International Nuclear Information System (INIS)

This study investigates the Mn-Ti-incorporated mesoporous silicate (Mn-Ti-MPS) as a photocatalyst for highly concentrated toluene removal in a plasma-photocatalytic hybrid system. Various Mn-Ti-MPS [Ti/Si molar ratio = 1/4, Mn/Ti molar ratio = 0.01/1 (1 mol%), 0.05/1 (5 mol%) and 0.1/1 (10 mol%)] photocatalysts were successfully synthesized using a common hydrothermal method without causing any structural damage. In the X-ray diffraction (XRD) pattern, the main peaks of the TiO2 anatase structure and MnO did not show. All samples displayed hexagonal specific peaks at 2.5 deg. (d100 plane), 4.1 deg. (d110 plane) and 4.7 deg. (d200 plane). This indicates that the Ti ions and Mn ions were well substituted into the Si ion sites in the framework of MCM-41. Their surface areas decreased compared with that of pure MCM-41, while the hexagonal straight pore size was distributed in a range of 2.5-3.5 nm. In the Mn-Ti-MPS, much more water and toluene molecules were absorbed compared to the Ti-MPS. From the X-ray photoelectron spectroscopy (XPS) result, it was determined that the hydrophilicity of the Mn-Ti-MPS was stronger than that of the Ti-MPS. Photocatalytic decomposition for highly concentrated toluene of 1000 ppm increased in the Mn-Ti-MPS when compared with the Ti-MPS, while toluene decomposition on 5 mol% Mn-Ti-MPS was remarkably enhanced to 80% in the plasma system. The conversion to CO2, however, did not improve in the case of the plasma-only system. Nonetheless, in the plasma-photocatalytic hybrid system, the conversion to CO2 for 5 mol% Mn-Ti-MPS reached 43% (in an 800 ppm toluene conversion)

Joint observations of the ETL ozone lidar and MPS system during the Los Angeles free-radical study  

Energy Technology Data Exchange (ETDEWEB)

Lidar systems measuring ozone concentration and aerosol profiles in the lower troposphere can make significant contributions to the understanding of chemical and transport processes for regional air quality assessment and control. The Environmental Technology Laboratory of the National Oceanic and Atmospheric Administration has developed a compact, efficient, transportable lower troposphere ozone lidar, which is capable of continuously measuring ozone concentration profiles from near the surface to about 3 km with high range resolution, and aerosol backscatter profiles from near the surface to about 10 km. The ozone lidar was deployed in two field experiments in California in 1993. The second field experiment, discussed here, was the Free Radical Study in the Los Angeles basin during September 1993. The ETL Mobile Profiling System (MPS), co-located with the lidar during the study, continuously measured surface and profiles of meteorological parameters using remote and in-situ techniques. The meteorological information is combined with the ozone lidar measurements to provide valuable insight into the complexity of the ozone profiles.

Fast and Accurate Simulation of Quantum Computing by Multi-Precision Mps: Recent Development  

Science.gov (United States)

The time-dependent matrix-product-state (TDMPS) simulation method has been known as one of fast simulation methods to study time-evolving quantum systems. Here, I report recent development of my open-source C++ library named ZKCM_QC designed for TDMPS simulations of quantum circuits with arbitrary floating-point precision. Simulation performance is reported for well-known quantum algorithms. In addition, it is numerically shown that a trustworthy simulation should be performed in multiprecision and should not involve truncations of nonzero Schmidt coefficients.

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)

Full Text Available The establishment of the District Assembly Common Fund (DACF in 1993 and concomitant percentage set aside for Members of Parliament (MPs in 2004 aims to support local governments and legislators in pro-poor development activities in their communities and constituencies. In spite of the importance of the MPs’ share of the District Assemblies Common Fund (MPsCF in financing local level development in Ghana, very little is known about monitoring systems and procedures on the disbursement and utilization of the funds. The study therefore assessed qualitative data derived from interviews with officials from selected Local Government Authorities (LGAs as well as other key stakeholders in the disbursement and utilization of the fund. The study findings point to the absence of legislative instrument on the management of the MPsCF. Further, monitoring of the fund was a responsibility shared by the LGAs and other external stakeholders. Finally, the effectiveness of monitoring the disbursement and utilization of the MPsCF was strongly influenced by the relationship between the Chief Executive of the Local Government Authority (LGCE and MPs in the local government area.

On the consistency of MPS  

Science.gov (United States)

The consistency of the Moving Particle Semi-implicit (MPS) method in reproducing the gradient, divergence and Laplacian differential operators is discussed in the present paper. Its relation to the Smoothed Particle Hydrodynamics (SPH) method is rigorously established. The application of the MPS method to solve the Navier-Stokes equations using a fractional step approach is treated, unveiling inconsistency problems when solving the Poisson equation for the pressure. A new corrected MPS method incorporating boundary terms is proposed. Applications to one dimensional boundary value Dirichlet and mixed Neumann-Dirichlet problems and to two-dimensional free-surface flows are presented.

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

Spectroscopy of MPS(3):DAMS(+) composite materials  

Science.gov (United States)

Composite materials are comprised of two separate components that are brought together to form a new material that exhibits unique properties not found in the individual components. The composite material studied in this work is a guest dye cation, (4-[4-(dimethylamino)-alpha-styrl]-1-methylpyridinium) or DAMS+, intercalated into an inorganic host lattice (MPS 3, where M = Cd2+ or Mn2+). MPS3 :DAMS+ exhibits high-efficiency second-harmonic generation (SHG), which is only observed when a material lacks a center of symmetry. There must be an organization of dye molecules upon intercalation to induce the noncentrosymmetry necessary for SHG. The formation of dye aggregates will be studied as a possible noncentrosymmetric arrangement. The intercalated materials (MPS3:DAMS+) exhibited spectral features of J-aggregates. These features included a sharp aggregate absorption and emission band, known as the J-band. There was a small Stokes shift (250 cm-1) between aggregate absorption and emission bands, and a red-shift between the J-band and isolated dye absorption band (3,700 cm-1). The low-energy tail of the emission J-band was theoretically modeled using the Urbach-Martienssen equation, while the high-energy states were fit to a Gaussian to determine aggregate disorder. Disorder was also modeled using a Monte-Carlo lineshape analysis program. From these theoretical models, the aggregate was found to be two-dimensional and weakly coupled. A variety of sample types were studied including intercalated powders and single crystals using absorbance, reflectance and emission spectroscopy. Reflectance spectra were directly compared with absorbance spectra using the Kramers-Kronig Transformation2 to determine that the surface aggregates and the interior aggregates were structurally similar. A new imaging microspectrophotometer was developed to investigate the topology of the composite materials. Kinetics of the intercalation front were studied and a layer-by-layer intercalation mechanism was developed. Surface studies using other materials indicated the polyanion nature of MPS3 :DAMS+ was essential for aggregation. Infrared microspectroscopy was used to determine the orientation of dye molecules on the surface of the large composite crystals. The DAMS+ in MPS 3:DAMS+ was shown to form two-dimensional brickwork aggregates with the molecules aligned "edge-on" on the surface and interior of the host lattice.

Skeletal response to lentiviral mediated gene therapy in a mouse model of MPS VII.  

Science.gov (United States)

Mucopolysaccharidosis VII (MPS VII) is an autosomal recessive, lysosomal storage disorder caused by ?-glucuronidase (GUSB) deficiency, resulting in the accumulation of glycosaminoglycans (GAGs), in a variety of cell types. Severe, progressive skeletal pathology, termed dysostosis multiplex, is a prominent clinical feature of MPS VII. We have evaluated a gene therapy protocol for its efficacy in preventing the development and progression of bone pathology in MPS VII mice treated with a lentiviral vector at birth or at 7 weeks. Two weeks after injections, high levels of vector expression were observed in liver, spleen and bone marrow and to a lesser extent in kidney, lung and heart. Widespread clearance of GAG storage was observed in somatic tissues of both groups and some clearance of neuronal storage was observed in mice treated from birth. Micro-CT analysis demonstrated a significant decrease in vertebral and femoral bone mineral volume, trabecular number, bone surface density and cortical bone thickness in both treatment groups. Lumbar and femoral bone lengths were significantly decreased in untreated MPS VII mice, while growth plate heights were increased and these parameters did not change upon treatment. Small improvements in performance in the open field and rotarod behaviour tests were noted. Overall, systemic lentiviral-mediated gene therapy results in a measurable improvement in parameters of bone mass and architecture as well as biochemical and enzymatic correction. Conversely, growth plate chondrocytes were not responsive to treatment, as evidenced by the lack of improvement in vertebral and femoral bone length and growth plate height. PMID:22525091

Science.gov (United States)

We discuss the numerical apsects of the Matrix Product State (MPS) representation for a large series of Fractional Quantum Hall states. We benchmark the MPS for several model states such as the Read-Rezayi series using both overlap, energies, densities and pair correlation functions. We discuss how accurate this description is depending on the geometry (sphere, disk or cylinder). As an application, we use the MPS to compute the size of the quasiholes for the Read-Rezayi series.

Structural and Functional Characterization of the Protein Kinase Mps1 in Arabidopsis thaliana  

Science.gov (United States)

In eukaryotes, protein kinases catalyze the transfer of a gamma-phosphate from ATP (or GTP) to specific amino acids in protein targets. In plants, protein kinases have been shown to participate in signaling cascades driving responses to environmental stimuli and developmental processes. Plant meristems are undifferentiated tissues that provide the major source of cells that will form organs throughout development. However, non-dividing specialized cells can also dedifferentiate and re-initiate cell division if exposed to appropriate conditions. Mps1 (Monopolar spindle) is a dual-specificity protein kinase that plays a critical role in monitoring the accuracy of chromosome segregation in the mitotic checkpoint mechanism. Although Mps1 functions have been clearly demonstrated in animals and fungi, its role in plants is so far unclear. Here, using structural and biochemical analyses here we show that Mps1 has highly similar homologs in many plant genomes across distinct lineages (e.g. AtMps1 in Arabidopsis thaliana). Several structural features (i.e. catalytic site, DFG motif and threonine triad) are clearly conserved in plant Mps1 kinases. Structural and sequence analysis also suggest that AtMps1 interact with other cell cycle proteins, such as Mad2 and MAPK1. By using a very specific Mps1 inhibitor (SP600125) we show that compromised AtMps1 activity hampers the development of A. thaliana seedlings in a dose-dependent manner, especially in secondary roots. Moreover, concomitant administration of the auxin IAA neutralizes the AtMps1 inhibition phenotype, allowing secondary root development. These observations let us to hypothesize that AtMps1 might be a downstream regulator of IAA signaling in the formation of secondary roots. Our results indicate that Mps1 might be a universal component of the Spindle Assembly Checkpoint machinery across very distant lineages of eukaryotes.

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.)

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

Energy Technology Data Exchange (ETDEWEB)

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.

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

Directory of Open Access Journals (Sweden)

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.

Email and political campaigning: the experience of MPs in Westminster  

Directory of Open Access Journals (Sweden)

Full Text Available Traditionally individual politicians communicated directly with their constituents, but the arrival of the mass media, especially television, eroded the role of direct communication. The development of new Information Communication Technologies (ICTs is now re-opening the use of direct communication as part of post-modern campaigning (Norris 2000, with the Internet providing an alternative to media relations. The World Wide Web has attracted great interest from political commentators, but so far email has been largely ignored. Yet the Web is a pull technique, whereas the push nature of email opens up new campaigning possibilities. Downes and Mui (2000 suggest that email represents potentially a 'killer app' which might revolutionize the way MPs approach re-election. A survey of Members of Parliament (MPs Assembly Members (AMs of the Welsh Assembly and Members of the Scottish Parliament (MSPs examines whether they have grasped the opportunities email represents. The research suggests that the outbound use of email for campaigning purposes is limited to a small number of pioneers. Resources, parliamentary culture and party affiliation all shape the use of email campaigning.

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.

Structural and mechanistic insights into Mps1 kinase activation  

Energy Technology Data Exchange (ETDEWEB)

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.

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

In the present study, single steam bubble condensation behaviors in subcooled water have been simulated using Moving Particle Semi-implicit (MPS) method. The liquid phase was modeled using moving particles and the two phase interface was set to be a movable boundary which can be tracked by the topological position of the interfacial particles. The interfacial heat transfer was determined according to the heat conduction through the interfacial liquid layer and the coupling between momentum and energy was specially treated. Computational results showed that the bubble experiences various deformations at lower degrees of liquid subcooling while it remains nearly spherical at higher degrees of liquid subcooling. The bubble lifetime is nearly proportional to bubble size and is prolonged at higher system pressures. Bubble lifetime obtained from the MPS method agrees well with the experiments of Kamei and Hirata (1986, 1987), however it is lower than the predictions of Sudhoff et al. (1982). The underestimation is caused by severe bubble deformation at lower degrees of subcooling. The present study exhibits some fundamental characteristics of single steam bubble condensation and is expected to be instructive for further applications of the MPS method to evaluate more complicated bubble dynamics problems.

Enhancement of performance and stability of MPS mesh-free particle method for multiphase flows characterized by high density ratios  

Science.gov (United States)

The paper presents an enhanced stabilized MPS (Moving Particle Semi-implicit) method for simulation of multiphase flows characterized by high density ratios. The developed method benefits from four previously developed schemes [1] as well as a novel one proposed for accurate, consistent modeling of density at the phase interface. The new scheme can be considered as an extended version of a commonly applied density smoothening scheme and is shown to keep the sharpness of spatial density variations while enhancing the stability and performance of simulations. Further, the paper highlights the importance of applying a Taylor series consistent scheme for calculation of pressure gradient in multiphase MPS-based simulations. By presenting a simple perturbation analysis, it is shown that some commonly applied MPS-based pressure gradient models are prone to increase the level of unphysical perturbations at the phase interface leading to numerical instabilities. The original MPS gradient model with a Gradient Correction [1] is shown to provide stable and accurate results even in case of violent multiphase flows characterized by high density ratios.

New Alleles of the Yeast MPS1 Gene Reveal Multiple Requirements in Spindle Pole Body Duplication  

Digital Repository Infrastructure Vision for European Research (DRIVER)

In Saccharomyces cerevisiae, the Mps1p protein kinase is critical for both spindle pole body (SPB) duplication and the mitotic spindle assembly checkpoint. The mps1–1 mutation causes failure early in SPB duplication, and because the spindle assembly checkpoint is also compromised, mps1–1 cells proceed with a monopolar mitosis and rapidly lose viability. Here we report the genetic and molecular characterization of mps1–1 and five new temperature-sensitive alleles of MPS1. Each of the six...

Novel vaccine delivery system induces robust humoral and cellular immune responses based on multiple mechanisms.  

Science.gov (United States)

Aiming to enhance the immunogenicity of H5N1 split vaccine, the development of a novel antigen delivery system based on quaternized chitosan hydrogel microparticles (Gel MPs) with multiple mechanisms of immunity enhancement is attempted. Gel MPs based on ionic cross-linking are prepared in a simple and mild way. Gel MPs are superior as a vaccine delivery system due to their ability to: 1) enhance cellular uptake and endosomal escape of antigens in dendritic cells (DCs); 2) significantly activate DCs; 3) form an antigen depot and recruit immunity cells to improve antigen capture. Further in vivo investigation shows that Gel MPs, in comparison to aluminum salts (Alum), LPS, and covalent cross-linking quaternized chitosan MPs (GC MPs), induce higher humoral and cellular immune responses with a mixed Th1/Th2 immunity. In conclusion, these results demonstrate that Gel MPs are efficient antigen delivery vehicles based on multiple mechanisms to enhance both humoral and cellular immune responses against H5N1 split antigen.

Preclinical dose ranging studies for enzyme replacement therapy with idursulfase in a knock-out mouse model of MPS II.  

Science.gov (United States)

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.

MRI morphometric characterisation of the paediatric cervical spine and spinal cord in children with MPS IVA (Morquio-Brailsford syndrome).  

Science.gov (United States)

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 on the spinal canal and cause spinal stenosis in MPS IVA? So far, there have been no standardised morphometric measurements of the paediatric MPS IVA cervical spine to evaluate whether there is pre-existing spinal stenosis predisposing to compressive myelopathy or whether this is purely an acquired process secondary to instability and compression. This study provides the first radiological quantitative analysis of the cervical spine and spinal cord in a series of affected children. MRI morphometry indicates that the MPS IVA spine is narrower at C1-2 level giving an inverted funnel shape. There is no evidence of a reduction in the Torg ratio (canal-body ratio) in the cervical spine. The spinal canal does not exceed 11 mm at any level, significantly smaller than normal historical cohorts (14 mm). The sagittal diameter and axial surface area of both spinal canal and cord are reduced. C1-2 level cord compression was evident in the canal-cord ratio but the Torg ratio was not predictive of cord compression. In MPS IVA the reduction in the space available for the cord (SAC) is multifactorial rather than due to congenital spinal stenosis. PMID:23404316

TP53 mutation-correlated genes predict the risk of tumor relapse and identify MPS1 as a potential therapeutic kinase in TP53-mutated breast cancers.  

Science.gov (United States)

Breast cancers (BC) carry a complex set of gene mutations that can influence their gene expression and clinical behavior. We aimed to identify genes driven by the TP53 mutation status and assess their clinical relevance in estrogen receptor (ER)-positive and ER-negative BC, and their potential as targets for patients with TP53 mutated tumors. Separate ROC analyses of each gene expression according to TP53 mutation status were performed. The prognostic value of genes with the highest AUC were assessed in a large dataset of untreated, and neoadjuvant chemotherapy treated patients. The mitotic checkpoint gene MPS1 was the most significant gene correlated with TP53 status, and the most significant prognostic marker in all ER-positive BC datasets. MPS1 retained its prognostic value independently from the type of treatment administered. The biological functions of MPS1 were investigated in different BC cell lines. We also assessed the effects of a potent small molecule inhibitor of MPS1, SP600125, alone and in combination with chemotherapy. Consistent with the gene expression profiling and siRNA assays, the inhibition of MPS1 by SP600125 led to a reduction in cell viability and a significant increase in cell death, selectively in TP53-mutated BC cells. Furthermore, the chemical inhibition of MPS1 sensitized BC cells to conventional chemotherapy, particularly taxanes. Our results collectively demonstrate that TP53-correlated kinase MPS1, is a potential therapeutic target in BC patients with TP53 mutated tumors, and that SP600125 warrant further development in future clinical trials.

Coupled Simulation of Seismic Wave Propagation and Failure Phenomena by Use of an MPS Method  

Science.gov (United States)

The failure of brittle materials, for example glasses and rock masses, is commonly observed to be discontinuous. It is, however, difficult to simulate these phenomena by use of conventional numerical simulation methods, for example the finite difference method or the finite element method, because of the presence of computational grids or elements artificially introduced before the simulation. It is, therefore, important for research on such discontinuous failures in science and engineering to analyze the phenomena seamlessly. This study deals with the coupled simulation of elastic wave propagation and failure phenomena by use of a moving particle semi-implicit (MPS) method. It is simple to model the objects of analysis because no grid or lattice structure is necessary. In addition, lack of a grid or lattice structure makes it simple to simulate large deformations and failure phenomena at the same time. We first compare analytical and MPS solutions by use of Lamb's problem with different offset distances, material properties, and source frequencies. Our results show that analytical and numerical seismograms are in good agreement with each other for 20 particles in a minimum wavelength. Finally, we focus our attention on the Hopkinson effect as an example of failure induced by elastic wave propagation. In the application of the MPS, the algorithm is basically the same as in the previous calculation except for the introduction of a failure criterion. The failure criterion applied in this study is that particle connectivity must be disconnected when the distance between the particles exceeds a failure threshold. We applied the developed algorithm to a suspended specimen that was modeled as a long bar consisting of thousands of particles. A compressional wave in the bar is generated by an abrupt pressure change on one edge. The compressional wave propagates along the interior of the specimen and is visualized clearly. At the other end of the bar, the spalling of the bar is reproduced numerically, and a broken piece of the bar is formed and falls away from the main body of the bar. Consequently, these results show that the MPS method effectively reproduces wave propagation and failure phenomena at the same time.

Exploring phase transitions by finite-entanglement scaling of MPS in the 1D ANNNI model  

Energy Technology Data Exchange (ETDEWEB)

We use the finite-entanglement scaling of infinite matrix product states (iMPS) to explore supposedly infinite order transitions. This universal method may have lower computational costs than finite-size scaling. To this end, we study possible MPS-based algorithms to find the ground states of the transverse axial next-nearest-neighbor Ising (ANNNI) model in a spin chain with first and second neighbor interactions and frustration. The ground state has four distinct phases with transitions of second order and one of supposedly infinite order, the Kosterlitz-Thouless transition. To explore phase transitions in the model, we study general quantities such as the correlation length, entanglement entropy and the second derivative of the energy with respect to the external field, and test the finite-entanglement scaling. We propose a scaling ansatz for the correlation length of a non-critical system in order to explore infinite order transitions. This method provides considerably less computational costs compared to the finite-size scaling method in [8], and quantities obtained by applying fixed boundary conditions (such as domain wall energy in [8]) are omitted. The results show good agreement with previous studies of finite-size scaling using DMRG.

Functional correction of CNS lesions in an MPS-IIIA mouse model by intracerebral AAV-mediated delivery of sulfamidase and SUMF1 genes.  

Science.gov (United States)

Mucopolysaccharidosis type IIIA (MPS-IIIA or Sanfilippo syndrome) is a lysosomal storage disorder caused by the congenital deficiency of sulfamidase (SGSH) enzyme and consequent accumulation of partially degraded heparan sulfate (HS) in lysosomes. The central nervous system (CNS) is the predominant site of tissue damage in MPS-IIIA. Here we describe a gene therapy approach for MPS-IIIA in a mouse model using recombinant adeno-associated virus serotype 5 (AAV2/5) as a vehicle to deliver therapeutic genes to the CNS. SUMF1 (SUlfatase Modifying Factor 1) exhibits an enhancing effect on sulfatase activity when co-expressed with sulfatases. Consistent with these findings, we demonstrated that co-delivery of SUMF1 and SGSH (via an AAV2/5-CMV-SGSH-IRES-SUMF1 vector) resulted in a synergistic increase in SGSH activity, both in primary neural cells and in murine brain. A study aimed at testing the therapeutic efficacy of simultaneous brain administration of SUMF1 and SGSH was then performed by injecting the lateral ventricles of newborn MPS-IIIA/normal mice with either AAV2/5-CMV-SGSH-IRES-SUMF1 or AAV2/5-CMV-GFP vectors. Widespread GFP expression was observed within the GFP-injected brain, and a stable and significant increase of SGSH activity was detected in several brain regions following SGSH-IRES-SUMF1 administration. Treatment with AAV2/5-CMV-SGSH-IRES-SUMF1 vectors resulted in a visible reduction in lysosomal storage and inflammatory markers in transduced brain regions. Finally, the MPS-IIIA mice treated with therapeutic genes displayed an improvement in both motor and cognitive functions. Our results suggest that early treatment of CNS lesions by AAV-mediated intraventricular injection of both SGSH and SUMF1 genes may represent a feasible therapy for MPS-IIIA. PMID:17725987

Development of a machine protection system for the Superconducting Beam Test Facility at Fermilab  

Energy Technology Data Exchange (ETDEWEB)

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 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 consideration.

Mps1 phosphorylation of condensin II controls chromosome condensation at the onset of mitosis.  

Science.gov (United States)

During mitosis, genomic DNA is condensed into chromosomes to promote its equal segregation into daughter cells. Chromosome condensation occurs during cell cycle progression from G2 phase to mitosis. Failure of chromosome compaction at prophase leads to subsequent misregulation of chromosomes. However, the molecular mechanism that controls the early phase of mitotic chromosome condensation is largely unknown. Here, we show that Mps1 regulates initial chromosome condensation during mitosis. We identify condensin II as a novel Mps1-associated protein. Mps1 phosphorylates one of the condensin II subunits, CAP-H2, at Ser492 during mitosis, and this phosphorylation event is required for the proper loading of condensin II on chromatin. Depletion of Mps1 inhibits chromosomal targeting of condensin II and accurate chromosome condensation during prophase. These findings demonstrate that Mps1 governs chromosomal organization during the early stage of mitosis to facilitate proper chromosome segregation. PMID:24934155

The Machine Protection System (MPS) is a device-safety system that is designed to prevent damage to hardware by generating interlocks, based upon the state of input signals generated by selected sub-system. It exists to protect key machinery such as the 50 kW and 1 MW RF Systems. When a fault state occurs, the MPS is capable of responding with an interlock signal within several microseconds. The Machine Protection System inputs are designed to be fail-safe. In addition, all fault conditions are latched and time-stamped. The ERL MPS is based on a National Instruments hardware platform, and is programmed by utilizing National Instruments development environment for a visual programming language.

Progress report on a study of inelastic K- reactions with polarized target in the Brookhaven MPS  

International Nuclear Information System (INIS)

The University of Massachusetts full-scale polarized-target run with the Brookhaven MPS was successfully carried out in late 1980, many years after being proposed. This study of K- inelastic processes represents the first application of the spin refrigerator target, and is unusual among polarized-target experiments in its use of a large multiparticle spectrometer for complex final states. It is also unusual in its emphasis on inelastic channels of S = -1 baryon resonances. Analysis of data (at 2.3 GeV c.m.) now in progress will establish the usefulness of the target system and also provide new information for the SU(6)/sub W/ (or other) quark model. 3 references, 1 figure

Random pharmacokinetic profiles of EC-MPS in children with autoimmune disease  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Therapy with mycophenolate mofetil (MMF has become a valuable therapeutic option in children with autoimmune disease. MMF prescription in children with autoimmune diseases differs from that in transplant recipients in terms of different dosing regimen, and concomitant administration of other immunosuppressive medications. Recently, another formulation of the same active compound, mycophenolic acid (MPA, has become available as enteric-coated Mycophenolate Sodium (EC-MPS. Dosing and pharmacokinetics of EC-MPS in pediatric autoimmune disease have never been studied. Methods We therefore performed a pilot study on 6 patients, who were treated with EC-MPS. All patients underwent 1-2 full 10-point pharmacokinetic (PK profiles over a 12-hour dosing interval. We compared the results with that of 22 similar patients on MMF therapy. Results Median EC-MPS dose was 724 mg/m2 (range 179-933 mg/m2. The MPA Area-Under-The-(Time-Concentration-Curves (AUCs on MMF and EC-MPS were comparable (54.4 mg × h/L on MMF and 44.0 mg × h/L on EC-MPS, n.s., Mann Whitney. After correcting for bioequivalence, the dose-normalized AUCs were also similar on both the formulations. However, PK profiles on EC-MPS were quite random, and time to maximum concentration varied from 30 minutes to 720 minutes. The concentration at six-hour correlated best with the AUC. This was different from a homogenous PK-profile on MPA. Conclusions EC-MPS has a different PK profile from MMF. The data suggest that patients on EC-MPS must undergo a complete PK profile to assess adequate exposure. The 6-hour concentration provides an estimate of the exposure and should be targeted between 3-4 mg/L.

Liga developer apparatus system  

Energy Technology Data Exchange (ETDEWEB)

A system to fabricate precise, high aspect ratio polymeric molds by photolithograpic process is described. The molds for producing micro-scale parts from engineering materials by the LIGA process. The invention is a developer system for developing a PMMA photoresist having exposed patterns comprising features having both very small sizes, and very high aspect ratios. The developer system of the present invention comprises a developer tank, an intermediate rinse tank and a final rinse tank, each tank having a source of high frequency sonic agitation, temperature control, and continuous filtration. It has been found that by moving a patterned wafer, through a specific sequence of developer/rinse solutions, where an intermediate rinse solution completes development of those portions of the exposed resist left undeveloped after the development solution, by agitating the solutions with a source of high frequency sonic vibration, and by adjusting and closely controlling the temperatures and continuously filtering and recirculating these solutions, it is possible to maintain the kinetic dissolution of the exposed PMMA polymer as the rate limiting step.

Numerical simulation on inertia controlled steam bubble condensation using MPS  

Science.gov (United States)

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.

Mutagenic potential scale developed for relative evaluation of biological system response to environments presenting different gamma exposure rates  

International Nuclear Information System (INIS)

The elaboration of a mutagenic potential scale (MPS) will be accomplished through the evaluation of the frequency of induced mutations in a plant biological system in different sites. The selection of these sites will be based on general public perception of risk to health. In this selection, it will include areas such ecological paradises and also neighborhoods of nuclear reactors and uranium mining and milling industry with potential radiological impact. The developed project foresees the contribution of other research groups that will also provide data from different sites. The referred scale will be built based on the response of the genetic system that gives color to the cells of Tradescantia (BNL 4430) stamen hair to mutagenic agents. Methodological improvements has been developed aiming the computerization of mutagenic events evaluation and statistical analysis of data that will significantly increase the efficiency of the system and obtention of results. Other biological systems of environmental quality are being added to the project, for future use. MPS should facilitate the general public and professionals of the nuclear area to understand risks, on a biological basis, of exposure from radiologically impacted environments. (author)

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

CheMPS2: a free open-source spin-adapted implementation of the density matrix renormalization group for ab initio quantum chemistry  

CERN Document Server

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. 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 D...

The machine protection system for the R&D energy recovery LINAC  

Energy Technology Data Exchange (ETDEWEB)

The Machine Protection System (MPS) is a device-safety system that is designed to prevent damage to hardware by generating interlocks, based upon the state of input signals generated by selected sub-systems. It protects all the key machinery in the R&D Project called the Energy Recovery LINAC (ERL) against the high beam current. The MPS is capable of responding to a fault with an interlock signal within several microseconds. The ERL MPS is based on a National Instruments CompactRIO platform, and is programmed by utilizing National Instruments' development environment for a visual programming language. The system also transfers data (interlock status, time of fault, etc.) to the main server. Transferred data is integrated into the pre-existing software architecture which is accessible by the operators. This paper will provide an overview of the hardware used, its configuration and operation, as well as the software written both on the device and the server side.

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

Energy Technology Data Exchange (ETDEWEB)

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)

Advanced Dewatering Systems Development  

Energy Technology Data Exchange (ETDEWEB)

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.

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 1s 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.

Heparin cofactor II-thrombin complex: a biomarker of MPS disease.  

Science.gov (United States)

The mucopolysaccharidoses are a group of lysosomal storage disorders caused by defects in the degradation of glycosaminoglycans. Each disorder is characterized by progressive multi-system disease with considerable clinical heterogeneity. The clinical heterogeneity of these disorders is thought to be related to the degree of the metabolic block in glycosaminoglycan degradation which in turn is related to the underlying mutation at the respective locus. There are currently no objective means other than longitudinal clinical observation, or the detection of a recurrent genetic mutation to accurately predict the clinical course for an individual patient, particularly when diagnosed early. In addition, there are no specific disease biomarkers that reflect the total body burden of disease. The lack of specific biomarkers has made monitoring treatment responses and predicting disease course difficult in these disorders. The recent introduction of enzyme replacement therapy for MPS I, II, and VI highlights the need for objective measures of disease burden and disease responsiveness. We show that serum levels of heparin cofactor II-thrombin complex is a reliable biomarker of the mucopolysaccharidoses. Untreated patients have serum levels that range from 3- to 112-fold above control values. In a series of patients with varying severity of mucopolysaccharidosis I, the serum complex concentration was reflective of disease severity. In addition, serum heparin cofactor II-thrombin levels showed responsiveness to various treatment regimens. We propose that serum levels of heparin cofactor II-thrombin complex may provide an important assessment and monitoring tool for patients with mucopolysaccharidosis. PMID:18511319

Proceedings of the 1st Nordic Optimization Symposium - 10th Nordic MPS meeting, Copenhagen 2006  

DEFF Research Database (Denmark)

On behalf of the Technical University of Denmark, the Danish Operations Research Society and the Nordic Section of the Mathematical Programming Society we welcome you to Copenhagen and the 1st Nordic Optimization Symposium - the 10th meeting of the Nordic MPS. The meetings of the Nordic MPS have evolved to be more that just a meeting on Mathematical Programming. They are a forum for discussing a wide range of related areas and practical cases. In the organizing committee we wanted the name of the meeting to reflect this. We have therefore in agreement with the board of the Nordic MPS suggested to add a new title, that reflects the much broader field that is our playground at these meetings. Still the odd trustworthy title â??Meeting of the Nordic MPSâ? has been maintained to demonstrate the origin of the symposium. It is our hope that future Nordic MPS meetings will carry on using this â??double nameâ?. The program includes 2 plenary lectures by Leo Kroon and Arne Drud and more than 50 contributed presentations. The symposium has this time expanded beyond our Nordic boundaries with participants from eg. the Netherlands, Italy and New Zealand. As a consequence the original 2 parallel streams we had in mind have extended to 3 throughout the symposium. It is our firm belief that this symposium will - like all the previous Nordic MPS meetings - be a fruitfull ground for collaboration and networking and therebye further tighten the ties between the Nordic countries in relation to optimization, Operations Research and Mathematical Programming. Finally we would like to thank our sponsors and supporter for their contributions. It has among other things made it possible to give free registration to a number of researchers from the Baltic countries and Ph.D. students in general. We wish you all an enjoyable 1st Nordic Optimization Symposium (10th Nordic MPS meeting) in Copenhagen.

The study of pressure source term in moving particle semi-implicit (MPS)  

Science.gov (United States)

In this paper pressure source terms proposed by different researcher are compared in term of pressure stability. In Moving Particle Semi-Implicit (MPS) method, the pressure error is compensated back into pressure Poisson equation as source term in order to enforce the incompressibility. However the non physical pressure fluctuation still remains an open problem in MPS method. In present study the hydrostatic model is used as example to study the pressure stability for each of the pressure source terms. The pressure at the fixed point over time is plotted and the fluctuation from the theoretical pressure is discussed.

Numerical simulation of sloshing with large deforming free surface by MPS-LES method  

Science.gov (United States)

Moving particle semi-implicit (MPS) method is a fully Lagrangian particle method which can easily solve problems with violent free surface. Although it has demonstrated its advantage in ocean engineering applications, it still has some defects to be improved. In this paper, MPS method is extended to the large eddy simulation (LES) by coupling with a sub-particle-scale (SPS) turbulence model. The SPS turbulence model turns into the Reynolds stress terms in the filtered momentum equation, and the Smagorinsky model is introduced to describe the Reynolds stress terms. Although MPS method has the advantage in the simulation of the free surface flow, a lot of non-free surface particles are treated as free surface particles in the original MPS model. In this paper, we use a new free surface tracing method and the key point is "neighbor particle". In this new method, the zone around each particle is divided into eight parts, and the particle will be treated as a free surface particle as long as there are no "neighbor particles" in any two parts of the zone. As the number density parameter judging method has a high efficiency for the free surface particles tracing, we combine it with the neighbor detected method. First, we select out the particles which may be mistreated with high probabilities by using the number density parameter judging method. And then we deal with these particles with the neighbor detected method. By doing this, the new mixed free surface tracing method can reduce the mistreatment problem efficiently. The serious pressure fluctuation is an obvious defect in MPS method, and therefore an area-time average technique is used in this paper to remove the pressure fluctuation with a quite good result. With these improvements, the modified MPS-LES method is applied to simulate liquid sloshing problems with large deforming free surface. Results show that the modified MPS-LES method can simulate the large deforming free surface easily. It can not only capture the large impact pressure accurately on rolling tank wall but also can generate all physical phenomena successfully. The good agreement between numerical and experimental results proves that the modified MPS-LES method is a good CFD methodology in free surface flow simulations.

Leukocytapheresis (LCAP) decreases the level of platelet-derived microparticles (MPs) and increases the level of granulocytes-derived MPs: a possible connection with the effect of LCAP on rheumatoid arthritis.  

Science.gov (United States)

Microparticles (MPs) are believed to play an important role in inflammatory diseases such as rheumatoid arthritis (RA). Leukocytapheresis (LCAP) is one of the options available for the treatment of RA. We analyzed the levels of MPs in RA, by flow cytometry, especially in relation to the effect of LCAP. Twenty female patients with RA were recruited into this study. Six of the 20 patients with RA further received LCAP. Plasma levels of platelet-derived MPs were high in patients with RA and are correlated with disease activity. LCAP significantly improved RA in all six patients. The numbers of platelet-derived MPs significantly decreased after the first session of LCAP, which was probably due to direct removal by LCAP. Mean numbers of platelet-derived MPs after four sessions of LCAP markedly decreased. The numbers of granulocyte-derived MPs, which are suggested to have an anti-inflammatory effect, were markedly increased after the first session of LCAP. These data suggest that removal of platelet-derived MPs and increase of granulocyte-derived MPs are novel mechanisms of LCAP as effective treatment in RA. PMID:19337689

POWER SYSTEMS DEVELOPMENT FACILITY  

Energy Technology Data Exchange (ETDEWEB)

This report discusses test campaign GCT3 of the Halliburton KBR transport reactor train with a Siemens Westinghouse Power Corporation (Siemens Westinghouse) particle filter system at the Power Systems Development Facility (PSDF) located in Wilsonville, Alabama. 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.

Numerical analysis of isothermal JET injection into a denser liquid pool using RD-MPS Method  

Energy Technology Data Exchange (ETDEWEB)

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.

Simulation of the QUEOS Experiment using Rigid Dynamic-Moving Particle Semi-Implicit (RD-MPS) Method  

International Nuclear Information System (INIS)

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

Series Bosch System Development  

Science.gov (United States)

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.

Evaluation of possible failure of the mononuclear phagocyte system after total splenectomy in rats  

Directory of Open Access Journals (Sweden)

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.

HLW Disposal System Development  

International Nuclear Information System (INIS)

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/cm3. 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

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.

Cloning and molecular characterization of BumaMPs1, a novel metalloproteinases from the venom of scorpion Buthus martensi Karsch.  

Science.gov (United States)

Scorpion venoms metalloproteinase is involved in a number of important biological, physiological and pathophysiological processes. In this work, a complete sequence of metalloproteinase was first obtained from venom of scorpion Buthus martensi and named as BumaMPs1. BumaMPs1 has 393 amino acid residues containing with a molecular mass of 44.53 kDa, showing an isoelectric point of 5.66. The primary sequence analysis indicated that the BumaMPs1 contains a zinc-binding motif (HELGHNLGISH), methionine-turn motif (YIM), disintegrin-like domain (ETCD) and N-glycosylation site. The multiple alignment of its deduced amino acid sequence and those of other metalloproteinase showed a high structural similarly, mainly among class reprolysin proteases. The phylogenetic analysis showed early divergence and independent evolution of BumaMPs1 from other metalloproteinase. PMID:24125658

On the Laplacian model for particle-based simulation using Moving-Particle Semi-implicit (Mps) Method  

Science.gov (United States)

A general form of Laplacian model is derived for the numerical framework of Moving Particle Semi-implicit (MPS) method. The existing proposals of MPS Laplacian model available in the open literature can indeed be reproduced from this general Laplacian model. Most importantly, the numerical accuracy of the evaluated Laplacian term particularly on the irregular particle layout can be further improved by adjusting the tuning parameter introduced in the general Laplacian model.

ODMR and optical investigations of vacancies in MPS3 lattices  

International Nuclear Information System (INIS)

Photoluminescence from lamellar chalcogenide lattices of CdPS3 and ZnPS3 has been examined using the techniques of photoexcitation, photoluminescence and optically detected magnetic resonance (ODMR) spectroscopy. Sharp absorption edges are observed at 3.295 and 3.50 eV in the ZnPS3 and CdPS3 lattices respectively. The band edge of ZnPS3 is about 1 eV higher in energy than previously reported and in agreement with recent band structure calculations. Peaks below the band edge due to stacking disorder were noted. A nearly isotropic ODMR signal without resolved nuclear hyperfine splittings is observed from CdPS3 after intercalation with pyridine. The signal is analyzed in terms of weakly exchange coupled donor and acceptor centers with g = 2. ZnPS3 crystals exhibit a complex, angle dependent ODMR spectrum prior to intercalation. The ODMR spectrum arises from a strongly coupled, two electron triplet center. Signals were associated with luminescence that is due to octahedral zinc vacancy centers in ZnPS3. The system was modeled as two strongly coupled electron spins with hyperfine interaction due to a nearby I = 1/2 31P nucleus. Photoluminescence spectra of fullerenes C60 and C70 are reported, for both microcrystalline solids and glassy solutions. Tentative analyses for the solution spectra are presented

Development of the accelerating system  

Energy Technology Data Exchange (ETDEWEB)

One of the main purposes of the 'Development of the Accelerating System' is developing a 100-MeV proton linac which accelerate proton beams from 20 MeV to 100 MeV by using 7 DTL (drift tube linac) tanks. Two of them were finished in the 2-nd stage of the project. The remaining part was also successfully fabricated and installed at Gyeongju site of KAERI. The MEBT is an essential component to extract and supply 20-MeV proton beams to users, and to match proton beams to the next accelerating structure for 100-MeV acceleration. The development of the MEBT has successfully finished. The project also developed the digital LLRF (low level RF) system which control the accelerating field within 1% in magnitude and 1 degree in phase. This system has been successfully tested in the 20-MeV linac operation at Daejeon site of KAERI. The modified version of the digital LLRF system will be used in the 100-MeV linac operation. The project also developed the beam diagnostic system. They are the strip-line type beam position monitor (BPM), the beam current monitor (CT), the beam loss monitor (BLM), and the emittance measurement system. They are used to measure the characteristics of the 20-MeV proton beams. The project also developed the EPIC-based control system. It is used to monitor the status of the accelerator and components, and to remotely control accelerator components. It has been used and modified in the 20-MeV linac operation. The modified version of the LLRF, diagnostics and control systems will be used in 100-MeV linac operation.

The safety of dipyridamole myocardial perfusion scintigraphy (MPS) in patients with end-stage chronic airways limitations (CAL)  

International Nuclear Information System (INIS)

Full text: Dipyridamole MPS is a well-established investigative technique in the diagnosis and pre-operative risk stratification of patients with possible coronary artery disease. However, there remains a concern of its use in patients with end-stage chronic airways limitations (CAL). Lung volume reduction surgery (LVRS) is a recent therapeutic option for such patients. The options for non-invasive pre-operative cardiac assessment in such patients are limited. This study reviewed the safety of dipyridamole use in such a clinical setting. 20 patients (10M, 10F, mean age 64.8 yrs) were evaluated. None had any history of ischaemic heart disease. Dipyridamole was administered intravenously at a dose of 0.05 mg/kg. Six patients remained asymptomatic throughout the procedure, while none experienced any chest pain. Two patients experienced moderate dyspnoea, which was rapidly relieved with aminophylline (100mg IV) during the recovery phase of the study. Two others developed mild dyspnoea; one settled spontaneously, while the other responded promptly to aminophylline. Aminophylline was administered to nine other patients to reverse minor symptoms (headache, flushing sensation). One other patient developed marked hypotension (SBP fell >20mmHg) and bradycardia, but no ECG changes for myocardial ischaemia. He responded well to aminophylline. His myocardial perfusion scan demonstrated extensive reversible myocardial ischaemia. Although the population size was small, dipyridamole appears safe to use in patients with end-stage CAL.

Characterization of a Putative Spindle Assembly Checkpoint Kinase Mps1, Suggests Its Involvement in Cell Division, Morphogenesis and Oxidative Stress Tolerance in Candida albicans  

Science.gov (United States)

In Saccharomyces cerevisiae MPS1 is one of the major protein kinase that governs the spindle checkpoint pathway. The S. cerevisiae structural homolog of opportunistic pathogen Candida albicans CaMPS1, is indispensable for the cell viability. The essentiality of Mps1 was confirmed by Homozygote Trisome test. To determine its biological function in this pathogen conditional mutant was generated through regulatable MET3 promoter. Examination of heterozygous and conditional (+Met/Cys) mps1 mutants revealed a mitosis specific arrest phenotype, where mutants showed large buds with undivided nuclei. Flowcytometry analysis revealed abnormal ploidy levels in mps1mutant. In presence of anti-microtubule drug Nocodazole, mps1 mutant showed a dramatic loss of viability suggesting a role of Mps1 in Spindle Assembly Checkpoint (SAC) activation. These mutants were also defective in microtubule organization. Moreover, heterozygous mutant showed defective in-vitro yeast to hyphae morphological transition. Growth defect in heterozygous mutant suggest haploinsufficiency of this gene. qRT PCR analysis showed around 3 fold upregulation of MPS1 in presence of serum. This expression of MPS1 is dependent on Efg1and is independent of other hyphal regulators like Ras1 and Tpk2. Furthermore, mps1 mutants were also sensitive to oxidative stress. Heterozygous mps1 mutant did not undergo morphological transition and showed 5-Fold reduction in colony forming units in response to macrophage. Thus, the vital checkpoint kinase, Mps1 besides cell division also has a role in morphogenesis and oxidative stress tolerance, in this pathogenic fungus.

Development of economic collector systems  

Energy Technology Data Exchange (ETDEWEB)

A comparison of systems of the different modular concepts was introduced for collector development work. The HELIOMAN-3-32/A collector module was used as the basis of comparison. Because of the results of this comparison, the single axis/horizontal north-south variant was given preference for development work. Activities for the design and development of the following components for the single axis horizontal trough following the sun took place: Parabolic mirror (1.5 m long, 1.1 m wide, thickness of glass 5 mm), absorber (38 mm diameter), trough structure (combination of several rows of mirrors), trough drive with 4 joint drive. Apart from this development work for a cylindrical paraboloid collector, the complete unit of a collector area was also considered (reducing the price).

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.

Remote Arrhythmia Monitoring System Developed  

Science.gov (United States)

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.

Reciprocating Feed System Development Status  

Science.gov (United States)

The reciprocating feed system (RFS) is an alternative means of providing high pressure propellant flow at low cost and system mass, with high fail-operational reliability. The RFS functions by storing the liquid propellants in large, low-pressure tanks and then expelling each propellant through two or three small, high-pressure tanks. Each RFS tank is sequentially filled, pressurized, expelled, vented, and refilled so as to provide a constant, or variable, mass flow rate to the engine. This type of system is much lighter than a conventional pressure fed system in part due to the greatly reduced amount of inert tank weight. The delivered payload for an RFS is superior to that of conventional pressure fed systems for conditions of high total impulse and it is competitive with turbopump systems, up to approximately 2000 psi. An advanced version of the RFS uses autogenous pressurization and thrust augmentation to achieve higher performance. In this version, the pressurization gases are combusted in a small engine, thus making the pressurization system, in effect, part of the propulsion system. The RFS appears to be much less expensive than a turbopump system, due to reduced research and development cost and hardware cost, since it is basically composed of small high- pressure tanks, a pressurization system, and control valves. A major benefit is the high reliability fail-operational mode; in the event of a failure in one of the three tank-systems, it can operate on the two remaining tanks. Other benefits include variable pressure and flow rates, ease of engine restart in micro-gravity, and enhanced propellant acquisition and control under adverse acceleration conditions. We present a system mass analysis tool that accepts user inputs for various design and mission parameters and calculates such output values payload and vehicle weights for the conventional pressure fed system, the RFS, the Autogenous Pressurization Thrust Augmentation (APTA) RFS, and turbopump systems. Using this tool, a preliminary design of a representative crew exploration vehicle (CEV) has been considered. The design parameters selected for a representative system were modeled after the orbital maneuvering system (OMS) on the Shuttle Orbiter, with an increase of roughly a factor of ten in the delta- V capability and a greater thrust (30,000 lbs, vs. 12,000 lbs). Both storable and cryogenic propellants were considered. Results show that a RFS is a low mass alternative to conventional pressure fed systems, with a substantial increase in payload capability and that it is weight-competitive with turbopump systems at low engine pressure (a few hundred psi); at high engine pressures, the APTA RFS appears to offer the highest payload. We also present the status of the RFS test bed fabrication, assembly, and checkout. This test bed is designed to provide flow rates appropriate for engines in the roughly 10,000 to 30,000 lb thrust range.

Development of biotechnology control systems.  

Science.gov (United States)

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.

KSTAR RF heating system development  

Energy Technology Data Exchange (ETDEWEB)

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.

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.

Development of controlled drilling system  

International Nuclear Information System (INIS)

In Japan, the soft sedimentary rock of the Neogene tertiary is being focused as a host rock for the High Level Radioactive Waste (HLW) disposal. Especially, the soft sedimentary rock at the offshore, region is thought to be one of the best candidates, since there is no driving force of the underground water. The measurement and logging in the bore hole in order to check the hydro-geological and geomechanical conditions of the host rock is a very important way to examine the potentially of the disposal candidates. The CRIEPI (Central Research Institute of Electric Power Industry) has been conducting the project about the controlled drilling technology and the measurement and logging technologies in its borehole. In 2000, as the beginning year of the project, we made the conceptual design of the drilling and measuring systems, and made key tools concerning each technology on an experimental basis. We have been developing sub tools constructing drilling and measuring systems since 2000, and applying these systems to the Horonobe site recent 5 years. We will briefly report the outline of the system and the results of drilling and measurement that were carried out at the Horonobe site. (author)

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

AGING SYSTEM DESIGN DEVELOPMENT STRATEGY  

Energy Technology Data Exchange (ETDEWEB)

This plan provides an overview, work to date, and the path forward for the design development strategy of the Aging cask for aging commercial spent nuclear fuel (CSNF) at the Yucca Mountain Project (YMP) repository site. Waste for subsurface emplacement at the repository includes US Department of Energy (DOE) high-level radioactive waste (HLW), DOE SNF, commercial fuel in dual-purpose canisters (DPCs), uncanistered bare fuel, naval fuel, and other waste types. Table 1-1 lists the types of radioactive materials that may be aged at YMP, and those materials that will not be placed in an aging cask or module. This plan presents the strategy for design development of the Aging system. 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.

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

Social networks, politics and Commitment 2.0: Spanish MPs on Facebook  

Directory of Open Access Journals (Sweden)

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.

The Micro-Pillar Shear-Stress Sensor MPS3 for Turbulent Flow  

Directory of Open Access Journals (Sweden)

Full Text Available Wall-shear stress results from the relative motion of a fluid over a body surface as a consequence of the no-slip condition of the fluid in the vicinity of the wall. To determine the two-dimensional wall-shear stress distribution is of utter importance in theoretical and applied turbulence research. In this article, characteristics of the Micro-Pillar Shear-Stress Sensor MPS3, which has been shown to offer the potential to measure the two-directional dynamic wall-shear stress distribution in turbulent flows, will be summarized. After a brief general description of the sensor concept, material characteristics, possible sensor-structure related error sources, various sensitivity and distinct sensor performance aspects will be addressed. Especially, pressure-sensitivity related aspects will be discussed. This discussion will serve as ‘design rules’ for possible new fields of applications of the sensor technology.

MEASUREMENT PROCESS OF SOFTWARE DEVELOPMENT PROJECTS FOR SUPPORTING STRATEGIC BUSINESS OBJECTIVES IN SOFTWARE DEVELOPING COMPANIES  

Directory of Open Access Journals (Sweden)

Full Text Available Software developing companies work in a competitive market and are often challenged to make business decisions with impact on competitiveness. Models accessing maturity for software development processes quality, such as CMMI and MPS-BR, comprise process measurements systems (PMS. However, these models are not necessarily suitable to support business decisions, neither to achieve strategic goals. The objective of this work is to analyze how the PMS of software development projects could support business strategies for software developing companies. Results taken from this work show that PMS results from maturity models for software processes can be suited to help evaluating operating capabilities and supporting strategic business decisions.

Recent developments at MLLTRAP: Improving the system for mass measurements and in-trap observation of nuclear decays  

Energy Technology Data Exchange (ETDEWEB)

Highlights: • A MPS system for m/q separation is developed. • A “detector trap” inside a Penning trap magnet is developed for the future MATS facility. • A novel type of recoil-distance experiment is envisaged. -- Abstract: The MLLTRAP double Penning-trap setup, installed at the Maier-Leibnitz Laboratory in Garching, presently serves as an environment for development work for mass spectrometry and decay-spectroscopy experiments at future radioactive ion beam (RIB) facilities. Here, an m/q separator is presently being set up as an element for beam transport of charge-bred ions, which are required for mass measurements of highly-charged ions. Moreover, a novel type of experimental setup, dedicated to in-trap decay spectroscopy, is under development to be implemented in the future MATS facility at FAIR. It combines the high-resolution mass-purification capabilities of a Penning trap with a customized “detector-trap” setup, consisting of an arrangement of position-sensitive Si-strip detectors that replaces the conventional ring electrode of the trap, providing both, ion storage and detection of decay products. In this way, decay-spectroscopy experiments of mass-selected nuclides, trapped as a carrier-free source, thus avoiding any background or scattering effects, will become feasible via direct in situ spectroscopy of stored ions.

Optimal Flow and Pressure Management in Machine Perfusion Systems for Organ Preservation  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Intra-organ flow is the most critical parameter in machine-perfused organ preservation systems (MPS). Ultrasonic flow sensors (UFS) are commonly employed in MPS. However, UFS are sensitive to changes in fluid composition and temperature and require recalibration. Novel Coriolis-type mass flow sensors (CFS) may be more suitable for MPS because the measurement technique is not amenable to these factors. The effect of viscosity, colloids, temperature, pressure, and preservation solution on flow ...

Mutagenic potential scale developed for relative evaluation of biological system response to environments presenting different gamma exposure rates; Escala de potencial mutagenico (EPM) desenvolvida para avaliar, relativamente a resposta de sistemas biologicos a ambientes apresentando maiores ou menores taxas de exposicao gama  

Energy Technology Data Exchange (ETDEWEB)

The elaboration of a mutagenic potential scale (MPS) will be accomplished through the evaluation of the frequency of induced mutations in a plant biological system in different sites. The selection of these sites will be based on general public perception of risk to health. In this selection, it will include areas such ecological paradises and also neighborhoods of nuclear reactors and uranium mining and milling industry with potential radiological impact. The developed project foresees the contribution of other research groups that will also provide data from different sites. The referred scale will be built based on the response of the genetic system that gives color to the cells of Tradescantia (BNL 4430) stamen hair to mutagenic agents. Methodological improvements has been developed aiming the computerization of mutagenic events evaluation and statistical analysis of data that will significantly increase the efficiency of the system and obtention of results. Other biological systems of environmental quality are being added to the project, for future use. MPS should facilitate the general public and professionals of the nuclear area to understand risks, on a biological basis, of exposure from radiologically impacted environments. (author) 7 refs.

Needs and Possibility of Involving Nuclear Power Plant in the Macedonian Power System  

International Nuclear Information System (INIS)

The Macedonian Power System (MPS) used to be a part of the former Yugoslav Power System, and it was connected to the European system by 400 kV transmission lines. At the present time, the MPS works isolated from the UCPTE, only connected to the Yugoslav and Greek power systems. The connections with the Bulgarian and Albanian power systems are on a lower voltage level. The reliability and stability of the MPS needs to be improved. Macedonia is located in the central area of the Balkan, where the transmission systems from other Balkan countries are crossing. in the near future, the Macedonian Power System needs to be linked to the European system. To prepare for the energy demand at the beginning of the 21-st century, when the local coal reserves get exhausted, Macedonia needs to start with activities for substitution of the existing coal-fired thermal power plants with nuclear plants. This paper discusses the activities for global development solutions in the area of power generation. (author)

Common N-acetylgalactosamine-6-sulfate sulfatase (GALNS exon mutations in Brazilian patients with mucopolysaccharidosis IVA (MPS IVA  

Directory of Open Access Journals (Sweden)

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.

Impact of high-dose, chemically modified sulfamidase on pathology in a murine model of MPS IIIA.  

Science.gov (United States)

Mucopolysaccharidosis type IIIA (MPS IIIA) is a neurodegenerative lysosomal storage disorder that results from a deficiency of sulfamidase (N-sulfoglucosamine sulfohydrolase), with consequential accumulation of its substrate, partially degraded heparan sulfate. Conventional doses (e.g. 1mg/kg) of intravenously delivered recombinant human sulfamidase (rhSGSH) do not improve neuropathology in MPS IIIA mice due to an inability to traverse the blood-brain barrier; however high-dose treatment or administration of enzyme that has been chemically modified to remove mannose-6-phosphate glycans has been shown to reduce neuropathology in related animal models. We have combined these approaches to evaluate the ability of 1, 5, 10 or 20mg/kg of similarly chemically modified or unmodified rhSGSH to reduce neuropathology following repeated intravenous delivery to adult MPS IIIA mice. rhSGSH was detected in brain homogenates from mice treated with all doses of modified rhSGSH and those receiving the two higher doses of unmodified rhSGSH, albeit at significantly lower levels. Immunohistochemically, rhSGSH visualized in the brain was localized to the endothelium, meninges and choroid plexus, with no convincing punctate intra-neuronal staining seen. This presumably underlies the failure of the treatment to reduce the relative level of a heparan sulfate-derived oligosaccharide (GlcNS-UA), or secondarily stored substrates that accumulate in MPS IIIA brain cells. However, modification of rhSGSH significantly increased its effectiveness in degrading GlcNS-UA in non-CNS tissues, potentially as a result of its reduced plasma clearance. If this observation is generally applicable, chemical modification may permit the use of significantly lower doses of lysosomal enzymes in patients currently receiving intravenous enzyme replacement therapy.

Heteroallelic missense mutations of the galactosamine-6-sulfate sulfatase (GALNS) gene in a mild form of Morquio disease (MPS IVA).  

Science.gov (United States)

Morquio disease (MPS IVA) is an autosomal recessive disorder caused by a deficiency of N-acetylgalactosamine-6-sulfate sulfatase (GALNS) activity. Patients commonly present in early infancy with growth failure, spondyloepiphyseal dysplasia, corneal opacification, and keratan sulfaturia, but milder forms have been described. We report on a patient who grew normally until age 5 years. Her keratan sulfaturia was not detected until adolescence, and she now has changes restricted largely to the axial skeleton. She has experienced only mildly impaired vision. At age 22, thin-layer chromatography of purified glycosaminoglycans showed some keratan sulfaturia. GALNS activity in fibroblast homogenate supernatants was 20 +/- 5% of controls (as compared to 5 +/- 3% of controls in severe MPS IVA, P < .003). Kinetic analysis of residual fibroblast GALNS activity in patient and parents revealed decreased K(m) and increased Vmax in the mother and daughter, but not in the father, compatible with compound heterozygosity. GALNS exons were amplified from patient genomic DNA and screened by SSCP. Two missense mutations, a C to T transition at position 335 (predicting R94C) and a T to G transversion at position 344 (predicting F97V), were found on sequencing an abnormally migrating exon 3 amplicon. Digestion of the amplicon with FokI and AccI restriction enzymes (specific for the R94C and F97V mutations, respectively) confirmed heterozygosity. In fibroblast transfection experiments, heterozygous R94C and F97V mutants independently expressed as severe and mild GALNS deficiency, respectively. We interpret these findings to indicate that our patient bears heteroallelic GALNS missense mutations, leading to GALNS deficiency and mild MPS IVA. Our findings expand the clinical and biochemical phenotype of MPS IVA, but full delineation of the genotype-phenotype relationship requires further study of native and transfected mutant cell lines.

Characterization of an MPS I-H Knock-In Mouse that Carries a Nonsense Mutation Analogous to the Human IDUA-W402X Mutation  

Science.gov (United States)

Here we report the characterization of a knock-in mouse model for the autosomal recessive disorder mucopolysaccharidosis type I-Hurler (MPS I-H), also known as Hurler syndrome. MPS I-H is the most severe form of ?-L-iduronidase deficiency. ?-L-iduronidase (encoded by the IDUA gene) is a lysosomal enzyme that participates in the degradation of dermatan sulfate and heparan sulfate. Using gene replacement methodology, a nucleotide change was introduced into the mouse Idua locus that resulted in a nonsense mutation at codon W392. The Idua-W392X mutation is analogous to the human IDUA-W402X mutation commonly found in MPS I-H patients. We found that the phenotype in homozygous Idua-W392X mice closely correlated with the human MPS I-H disease. Homozygous W392X mice showed no detectable ?-L-iduronidase activity. We observed a defect in GAG degradation as evidenced by an increase in sulfated GAGs excreted in the urine and stored in multiple tissues. Histology and electron microscopy also revealed evidence of GAG storage in all tissues examined. Additional assessment revealed bone abnormalities and altered metabolism within the Idua-W392X mouse. This new mouse will provide an important tool to investigate therapeutic approaches for MPS I-H that cannot be addressed using current MPS I-H animal models.

Information Systems Development as a Research Method  

Directory of Open Access Journals (Sweden)

Full Text Available This paper takes the stance that some cases of information systems development can be considered knowledge creating activities, and, in those cases, information systems development can be a legitimate research method. In these cases not only is knowledge created about the development process itself but also a deeper understanding emerges about the organisational problem that the system is designed to solve. The paper begins with a brief overview of research in the design sciences and a comparison of research methods that are concerned with the design, and use, of information systems. This is followed by an assessment of the way systems development as a research method deals with the scientific research processes of data collection, analysis, synthesis and display. A case study, where the systems development research method was use, is described to illustrate the method and give the reader a better understanding of the approach.

The Designer Aminoglycoside NB84 Significantly Reduces Glycosaminoglycan Accumulation Associated with MPS I-H in the Idua-W392X Mouse  

Science.gov (United States)

Suppression therapy utilizes compounds that suppress translation termination at in-frame premature termination codons (PTCs) to restore full-length, functional protein. This approach may provide a treatment for diseases caused by nonsense mutations such as mucopolysaccharidosis type I-Hurler (MPS I-H). MPS I-H is a lysosomal storage disease caused by severe ?-L-iduronidase deficiency and subsequent lysosomal glycosaminoglycan (GAG) accumulation. MPS I-H represents a good target for suppression therapy because the majority of MPS I-H patients carry nonsense mutations, and restoration of even a small amount of functional ?-L-iduronidase may attenuate the MPS I-H phenotype. In this study, we investigated the efficiency of suppression therapy agents to suppress the Idua-W392X nonsense mutation in an MPS I-H mouse model. The drugs tested included the conventional aminoglycosides gentamicin, G418, amikacin, and paromomycin. In addition, the designer aminoglycosides NB54 and NB84, two compounds previously designed to mediate efficient PTC suppression with reduced toxicity, were also examined. Overall, NB84 suppressed the Idua-W392X nonsense mutation much more efficiently than any of the other compounds tested. NB84 treatment restored enough functional ?-L-iduronidase activity to partially reverse abnormal GAG accumulation and lysosomal abundance in mouse embryonic fibroblasts derived from the Idua-W392X mouse. Finally, in vivo administration of NB84 to Idua-W392X mice significantly reduced urine GAG excretion and tissue GAG storage. Together, these results suggest that NB84-mediated suppression therapy has the potential to attenuate the MPS I-H disease phenotype.

Space Launch Flight Termination System initial development  

Science.gov (United States)

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.

Development of coaxial counterrotating rotary tilling system  

Energy Technology Data Exchange (ETDEWEB)

A computer simulation of the soil reaction force was very helpful to develop the new rotary tilling system of a walking tractor which uses coaxial simultaneously counterrotating blades to stabilize the tractor while tilling. The simulation revealed that the fluctuation of the soil reaction force generated by the new tilling system retaining a conventional blade arrangement is great compared with the ordinary tilling system, and that the system with an appropriate blade arrangement improves this fluctuation. The walking tractor developed using this computer simulation tool demonstrates the capability of being operated stably up to its maximum output of rotary shafts.

Development of borehole multiple deformation sensor system  

Science.gov (United States)

The multiple deformation sensor system for small diameter borehole is required for the long term monitoring of deformation of rock mass of high-level radioactive waste disposal site. The conventional electric monitoring systems are difficult to apply for a long term monitoring in many cases because of the sensor failure caused by lowering of insulation or other problems and only available for the large borehole and for 6 or less measurement sections. The Borehole Multiple Deformation Sensor System was developed based on the FBG (Fiber Bragg Grating) sensor technology that is expected to have longer life time than electric systems. The developed system can be set in a 66 mm diameter borehole and available for 9 or more measurement sections that can be hardly achieved by electric systems. The sensor system is applying for the monitoring of ground deformation in the Horonobe Underground Research Laboratory in Japan.

[Therapy for systemic metabolic disorders based on the detection of basic corneal landmarks in childhood].  

Science.gov (United States)

Many systemic lysosomal storage disorders show basic corneal opacities already in childhood. The lysosome is a cell organelle, produced by Golgi's apparatus, that is surrounded by a membrane and contains hydrolytic enzymes that break down food molecules, especially proteins and other complex molecules. The ophthalmologist's precise diagnosis of corneal clouding at the slit-lamp may reveal the correct interpretation of the specific lysosomal storage disorder. It is very important to diagnose such diseases as soon as possible because today the development of systemic enzymatic therapies has broadened the therapeutic armamentarium for the current standard of care. The following corneal landmarks of systemic storage diseases and of the modern systemic therapy are presented: cornea verticillata in Fabry's disease, periodic infusion of alpha-galactosidase a; Kayser-Fleischer's ring in Wilson's disease, zinc, trienetin, low copper diet; multiple, punctiform crystals in cystinosis, cysteamine, Raptor RP 103(DR cysteamine) that reduces the cytotoxity in form of continous dissolving of cystine from lysosome, renal transplantation, haematopoietic stem cell transplantation; peripheral ring, but not true lipid arc, and moderate stromal haze in LCAT-deficiency, injection of recombinant enzyme or of encapsulated LCAT-secreting cells; diffuse stromal haze in mucopolysaccharidoses (MPS). Enzyme replacement therapy is currently indicated for MPS I, MPS II, and MPS VI, haematopoietic stem cell transplantation; painful, bilateral pseudo-dendritic opacities in tyrosinemia type II (eponym: Richner-Hanhart syndrome), low phenylalanine and tyrosine diet result in complete disappearance of corneal alterations with a consecutive painfree period. Strict diet during the whole life is necessary to prevent corneal recurrences and the occurrence of palmo-plantar keratoses. Such therapies can enable the patient to lead an otherwise normal life for decades. PMID:23794426

Hydrogen storage and delivery system development: Fabrication  

Energy Technology Data Exchange (ETDEWEB)

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.

Development of control system for measuring system with CAMAC  

Energy Technology Data Exchange (ETDEWEB)

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.

The HS6000/20 development system  

International Nuclear Information System (INIS)

In the actual control system of MEA, NIKHEF-K three color displays are in use for graphical representation of the accelerator status information. At the moment the quality of the color displays is bad. The HS6000 development system of the English company Syntel seems to offer a possible solution to replace these displays. In the development system software is developed which finally may run on a target module. The target module, consisting of a processor card with memory and RS232 port and a graphical card, takes care for the control of a color display. The institute has disposed of an experimental set up during two weeks in order to investigate the possibilities and limitations of the development system. The HS6000 development system runs under the OS-9 multi-user and multi-tasking operating system. The operating system takes care for a part of the necessary software to render a computer valuable. The OS-9 operating system disposes of about 60 utility commands. A feature of OS-9 is the application of modular software technique which are based upon memory modules. The interface between the user and the internal functions of the operating system is formed from the shell, the OS-9 command-interpreter code. The software, which has to run on the target module, is written with the help of the Mmacs screen editor, the draw program and the medit editor. The draw program and the medit editor form part of the EGOS ( Enhanced Graphical Output Software) packet. The EGOS packet is a multi-tasking graphical interface for the OS-9 operating system.

The development of air cooled condensation systems  

International Nuclear Information System (INIS)

EGI - Contracting/Engineering has had experience with the development of air cooled condensing systems since the 1950's. There are two accepted types of dry cooling systems,the direct and the indirect ones. Due to the fact that the indirect system has several advantages over the direct one, EGI's purpose was to develop an economic, reliable and efficient type of indirect cooling system, both for industrial and power station applications. Apart from system development, the main components of dry cooling plant have been developed as well. These are: the water-to-air heat exchangers; the direct contact (DC, or jet) condenser; the cooling water circulating pumps and recovery turbines; and the peak cooling/preheating units. As a result of this broad development work which was connected with intensive market activity, EGI has supplied about 50% of the dry cooling plants employed for large power stations all over the world. This means that today the cumulated capacity of power units using Heller type dry cooling systems supplied and contracted by EGI is over 6000 MW

Common N-acetylgalactosamine-6-sulfate sulfatase (GALNS) exon mutations in Brazilian patients with mucopolysaccharidosis IVA (MPS IVA)  

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: English Abstract in english 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 o [...] f 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 development of ZPRL digital control system  

International Nuclear Information System (INIS)

Zero Power Reactor at Lung-Tan (ZPRL) is a small open-pool type research reactor located at Lung-Tan, Taiwan. The reactor achieved its first criticality in 1971. An analog control system has been used for almost over 20 years and the power regulating function is found gradually out of order. Therefore, we decided to develop a digital control system to replace the existing analog one. A prototype system has been developed and under on-line test now. The proposed ZPRL digital control system consists of three personal computers. These computers are used as (1) operator console, (2) data acquisition and control system, and (3) auxiliary and backup system. The operator console contains all the man-machine interface functions in the form of graphic display. The data acquisition and control system converts the analog signals into digital ones and feeds to the other two computers. The auxiliary and backup system normally emulates a strip chart recorder for the linear and logarithmic neutron powers and also acts as a transient recorder to keep the trace of the operating conditions on demand or when the reactor scrams. On-line test shows that the system does assure a satisfactory performance. It is not only as good as the analog system but also has the advantages of flexibility, testibility, and a user friendly man-machine interface. (author)

Development of a Radioactive Waste Assay System  

Energy Technology Data Exchange (ETDEWEB)

Nuclear Act of Korea requires the manifest of low and intermediate level radioactive waste generated at nuclear power plants prior to disposal sites.Individual history records of the radioactive waste should be contained the information about the activity of nuclides in the drum, total activity, weight, the type of waste. A fully automated nuclide analysis assay system, non-destructive analysis and evaluation system of the radioactive waste, was developed through this research project. For the nuclides that could not be analysis directly by MCA, the activities of the representative {gamma}-emitters(Cs-137, Co-60) contained in the drum were measured by using that system. Then scaling factors were used to calculate the activities of {alpha}, {beta}-emitters. Furthermore, this system can automatically mark the analysis results onto the drum surface. An automated drum handling system developed through this research project can reduce the radiation exposure to workers. (author). 41 refs., figs.

Expert system development for probabilistic load simulation  

Science.gov (United States)

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.

System reliability developments in structural engineering  

International Nuclear Information System (INIS)

Two major limitations occur in present structural design code developments utilizing reliability theory. The notional system reliabilities may differ significantly from calibrated component reliabilities. Secondly, actual failures are often due to gross errors not reflected in most present code formats. A review is presented of system reliability methods and further new concepts are developed. The incremental load approach for identifying and expressing collapse modes is expanded by employing a strategy to identify and enumerate the significant structural collapse modes. It further isolates the importance of critical components in the system performance. Ductile and brittle component behavior and strength correlation is reflected in the system model and illustrated in several examples. Modal combinations for the system reliability are also reviewed. From these developments a system factor can be addended to component safety checking equations. Values may be derived from system behavior by substituting in a damage model which accounts for the response range from component failure to collapse. Other strategies are discussed which emphasize quality assurance during design and in-service inspection for components whose behavior is critical to the system reliability. (Auth.)

NASA Redox Storage System Development Project  

Science.gov (United States)

The Redox Storage System Technology Project was jointly supported by the U.S. Department of Energy and NASA. The objectives of the project were to develop the Redox flow battery concept and to probe its technical and economic viability. The iron and chromium redox couples were selected as the reactants. Membranes and electrodes were developed for the original mode of operating at 25 C with the reactants separated by an ion-exchange membrane. Analytical capabilities and system-level operating concepts were developed and verified in a 1-kW, 13-kWh preprototype system. A subsequent change was made in operating mode, going to 65 C and using mixed reactants. New membranes and a new electrode catalyst were developed, resulting in single cell operation as high as 80 mA/sq cm with energy efficiencies greater than 80 percent. Studies indicate a likely system cost of about $75/kWh. Standard Oil of Ohio (Sohio) has undertaken further development of the Redox system. An exclusive patent license was obtained from NASA by Sohio. Transfer of Redox technology to Sohio is supported by the NASA Technology Utilization Office.

Hydrogen storage and delivery system development  

Energy Technology Data Exchange (ETDEWEB)

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.

Clover development during spaceflight: A model system  

Science.gov (United States)

The development of legume root nodules was studied as a model system for the examination of gravitational effects on plant root development. In order to examine whether rhizobial association with clover roots can be achieved in microgravity, experiments were performed aboard the KC-135 parabolic aircraft and aboard the sounding rocket mission Consort 3. Binding of rhizobia to roots and the initial stages of root nodule development successfully occurred in microgravity. Seedling germination experiments were performed in the sliding block device, the Materials Dispersion Apparatus, aboard STS-37. When significant hydration of the seeds was achieved, normal rates of germination and seedling development were observed.

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.

Identification, expression, and biochemical characterization of N-acetylgalactosamine-4-sulfatase mutations and relationship with clinical phenotype in MPS-VI patients  

Energy Technology Data Exchange (ETDEWEB)

Maroteaux-Lamy syndrome, or mucopolysaccharidosis type VI (MPS-VI), is a lysosomal storage disorder characterized by the defective degradation of dermatan sulfate due to the deficiency of N-acetylgalactosamine-4-sulfatase (4S). The clinical severity of MPS-VI ranges in a continuum from mildly affected to severely affected patients. Mutations in MPS-VI patient samples were identified by chemical cleavage and direct DNA sequencing of PCR products derived from patient cDNA. Five amino acid substitutions were identified (T92M, R95Q, Y210C, H393P, and L498P), individually introduced into the wild-type 4S cDNA by site-directed in vitro mutagenesis, and transfected into Chinese hamster ovary cells. Three of the five mutations (R95Q, Y210C, and H393P) were observed in > 1 of 25 unrelated MPS-VI patients; however, the mutations were not found in 20 control individuals. The residual 4S activity and protein (biochemical phenotype) were determined for each mutant in order to confirm their identity as mutations and to dissect the contribution of each mutant allele to the overall clinical phenotype of the patient. For each patient, the combined biochemical phenotypes of the two 4S mutant alleles demonstrated a good correspondence with the observed clinical phenotype (with the possible exception of a patient who was a compound heterozygote for T92M and L498P). This preliminary correspondence between genotype and the phenotype in MPS-VI may, with further refinement, contribute to the assessment of therapeutic approaches for MPS-VI patients. 30 refs., 4 tabs.

Development of Solar Powered Irrigation System  

Science.gov (United States)

Development of a solar powered irrigation system has been discussed in this paper. This system would be SCADA-based and quite useful in areas where there is plenty of sunshine but insufficient water to carry out farming activities, such as rubber plantation, strawberry plantation, or any plantation, that requires frequent watering. The system is powered by solar system as a renewable energy which uses solar panel module to convert Sunlight into electricity. The development and implementation of an automated SCADA controlled system that uses PLC as a controller is significant to agricultural, oil and gas monitoring and control purpose purposes. In addition, the system is powered by an intelligent solar system in which solar panel targets the radiation from the Sun. Other than that, the solar system has reduced energy cost as well as pollution. The system is equipped with four input sensors; two soil moisture sensors, two level detection sensors. Soil moisture sensor measures the humidity of the soil, whereas the level detection sensors detect the level of water in the tank. The output sides consist of two solenoid valves, which are controlled respectively by two moistures sensors.

Applying Prolog to Develop Distributed Systems  

CERN Document Server

Development of distributed systems is a difficult task. Declarative programming techniques hold a promising potential for effectively supporting programmer in this challenge. While Datalog-based languages have been actively explored for programming distributed systems, Prolog received relatively little attention in this application area so far. In this paper we present a Prolog-based programming system, called DAHL, for the declarative development of distributed systems. DAHL extends Prolog with an event-driven control mechanism and built-in networking procedures. Our experimental evaluation using a distributed hash-table data structure, a protocol for achieving Byzantine fault tolerance, and a distributed software model checker - all implemented in DAHL - indicates the viability of the approach.

Feedwater system diagnostic development using distributed simulation  

Energy Technology Data Exchange (ETDEWEB)

A real-time diagnostic system for the EBR-II steam plant has been developed using the DISYS Diagnostic and Control Guidance Expert System. Diagnostic rules were developed to distinctly identify ten specific fault conditions and were tested using a real-time distributed simulation of the EBR-II steam plant. The distributed simulation is implemented in three separate programs in a VAX cluster and is coordinated through a distributed simulation manager operating in a UNIX workstation. The multi-program DISYS system currently operates in the same UNIX workstation as the simulation manager and obtains the simulated data from a shared memory segment maintained by the simulation manager. Future work includes modifying the DISYS system to improve the fault detection of rapid transients and enable it to detect gradual long term trends.

Development of a shear stress sensor to analyse the influence of polymers on the turbulent wall shear stress  

Energy Technology Data Exchange (ETDEWEB)

The drag reducing effect of polymers in a channel flow is well known and it is assumed that the polymer filaments interfere with the turbulent structures in the very near-wall flow. To analyse their precise effect, a micro-pillar shear stress sensor (MPS{sup 3}) measurement system is developed which allows the detection of wall shear stress at high spatial and temporal resolutions. Different manufacturing techniques for the required micro-pillars are discussed and their influence on the flow is investigated evidencing the non-intrusive character of the pillars. Subsequently, a complete calibration is presented to relate the recorded deflection to wall shear stress values and to assure the correct detection over the whole expected frequency spectrum. A feasibility study about the ability to visualize the two-dimensional wall shear stress distribution completes the discussion about the validity of MPS{sup 3}. In the last step, the drag reduction of a polymer filament grafted on a micro-pillar compared to a plain pillar and the application of MPS{sup 3} in an ocean-type polymer solution are investigated. The results confirm the expected behaviour found in the literature.

System development and asset management under restructuring  

International Nuclear Information System (INIS)

In many developed countries the electricity infrastructure contains ageing assets. Because of the need of a continuing operation and higher load factors on the network, the opportunities for replacement or refurbishment are limited. These must be regarded as an opportunity to review the structure of the system and to consider the design and development required to meet the new requirements, taking advantage of new available technologies: HVDC, FACTS, cables, etc. The symposium examines assets management issues and assesses strategies for overhauling existing systems, taking into account the impact on market operation, on supply security and environment

Hybrid systems look good for developing countries  

Energy Technology Data Exchange (ETDEWEB)

Although interconnected grids are increasing in global importance, they are unacceptable in many thinly settled developing countries for technical and economic reasons. Decentralized electricity supply is thus of great interest in such places. Hybrid systems of 10 to 100 kW capacity which are comprised of a combination of diesel generators and renewable energy technologies may offer a future option to the traditional diesel only systems.

Development of scanning control system for proton therapy system  

International Nuclear Information System (INIS)

Proton Therapy is a kind of radiation therapy which can concentrate dose distribution in the tumor, and is widely used today. Pencil beam scanning method has been developed as an advanced approach to proton therapy. We have developed this method in collaboration with National Cancer Center Hospital East (NCCE). The scanning control system is required to scan beam spot in precise position and detect it with high accuracy. In addition, it is necessary to design a beam current stabilize control system which can secure stable dose distribution. We have developed an advanced scanning control system which has a monitoring system to detect beam position with resolution of les than 0.1 mm and fast sampling time (less than 20 ?s), and a beam current controller to stabilize beam current within ±1%. The pencil beam scanning treatment is scheduled to start within 2011. (author)

Development of an omnidirectional vision system  

Directory of Open Access Journals (Sweden)

Full Text Available Omnidirectional vision systems can provide images with a 360degrees 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 resulting 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.

Development of an automatic reactor inspection system  

International Nuclear Information System (INIS)

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

Development of subpicosecond pulse radiolysis system  

CERN Document Server

The highest time resolution of the pulse radiolysis had remained about 30 ps since the late 1960s. To make clear the primary processes in the radiation chemistry and physics within 30 ps, we developed a stroboscopic pulse radiolysis system for the absorption spectroscopy with the time resolution of 2.0 ps (10-90% rise time). The time resolution of 2.0 ps was estimated from the time-dependent behavior of the hydrated electrons. The system consists of a subpicosecond electron linac as an irradiation source, a femtosecond laser as an analyzing light and a jitter compensation system.

Statement about researches relative to the operation stability of the MPS P230 of Ariane 5; Point sur les recherches relatives a la stabilite de fonctionnement du MPS P230 d'Ariane 5  

Energy Technology Data Exchange (ETDEWEB)

This paper makes a statement about the researches carried out in the framework of the ASSM (Aerodynamics of Segmented Solid Motors) research program on the operation stability of the MPS P230 solid propellant engine of the French Ariane 5 launcher. After a brief historical recall of the works performed on this topic during the last 10 years, the present day situation is detailed. The feasibility of a numerical capture of the instability phenomenon is now achieved and 3 scenarios leading to swirl flow instabilities could be identified. These scenarios were validated using numerical simulation, simulation in cold gases, and launcher tests. However, one scenario based on a strong instability mechanism, seems to better fit with the observations made on the P230 engine and will deeply influence the scientific strategy of the research program.

Full Text Available Quality is the life of embedded systems, and thetesting is a basic guarantee for stable and reliable operation ofthe embedded systems. Testing is an important part in thedevelopment of any system as it represents the ultimateverification and validation of specification, design and code.The goal of testing is to design a series of test cases that has thehighest likelihood of finding most of the errors with a minimumamount of time and effort. The techniques used to test theembedded systems provide systematic guidance for designingtests that exercise the internal logic of Embedded Systemcomponents and test the input and output domains of theprogram to uncover errors in program function, behavior andperformance. Simulation can be used as an alternative to theactual target system for a significant portion of the testingeffort, saving developers time and money, as well as increasingtest coverage and providing better debugging facilities, itbecomes much more necessary to construct embedded systemstesting environment.

Space Fission Propulsion System Development Status  

Science.gov (United States)

The world's first man-made self-sustaining fission reaction was achieved in 1942. Since then fission has been used to propel submarines, generate tremendous amounts of electricity, produce medical isotopes, and provide numerous other benefits to society. Fission systems operate independently of solar proximity or orientation, and are thus well suited for deep space or planetary surface missions. In addition, the fuel for fission systems (enriched uranium) is virtually non-radioactive. The primary safety issue with fission systems is avoiding inadvertent system start. Addressing this issue through proper system design is straight-forward. Despite the relative simplicity and tremendous potential of space fission systems, the development and utilization of these systems has proven elusive. The first use of fission technology in space occurred 3 April 1965 with the US launch of the SNAP-10A reactor. There have been no additional US uses of space fission systems. While space fission systems were used extensively by the former Soviet Union, their application was limited to earth-orbital missions. Early space fission systems must be safely and affordably utilized if we are to reap the benefits of advanced space fission systems. NASA's Marshall Space Flight Center, working with Los Alamos National Laboratory (LANL), Sandia National Laboratories, and others, has conducted preliminary research related to a Safe Affordable Fission Engine (SAFE). An unfueled core has been fabricated by LANL, and resistance heaters used to verify predicted core thermal performance by closely mimicking heat from fission. The core is designed to use only established nuclear technology and be highly testable. In FY01 an energy conversion system and thruster will be coupled to the core, resulting in an 'end-to-end' nuclear electric propulsion demonstrator being tested using resistance heaters to closely mimic heat from fission. Results of the SAFE test program will be presented. The applicability of a SAFE-powered electric propulsion system to outer planet science missions will also be discussed.

Development of Human System Integration at NASA  

Science.gov (United States)

Human Systems Integration seeks to design systems around the capabilities and limitations of the humans which use and interact with the system, ensuring greater efficiency of use, reduced error rates, and less rework in the design, manufacturing and operational deployment of hardware and software. One of the primary goals of HSI is to get the human factors practitioner involved early in the design process. In doing so, the aim is to reduce future budget costs and resources in redesign and training. By the preliminary design phase of a project nearly 80% of the total cost of the project is locked in. Potential design changes recommended by evaluations past this point will have little effect due to lack of funding or a huge cost in terms of resources to make changes. Three key concepts define an effective HSI program. First, systems are comprised of hardware, software, and the human, all of which operate within an environment. Too often, engineers and developers fail to consider the human capacity or requirements as part of the system. This leads to poor task allocation within the system. To promote ideal task allocation, it is critical that the human element be considered early in system development. Poor design, or designs that do not adequately consider the human component, could negatively affect physical or mental performance, as well as, social behavior. Second, successful HSI depends upon integration and collaboration of all the domains that represent acquisition efforts. Too often, these domains exist as independent disciplines due to the location of expertise within the service structure. Proper implementation of HSI through participation would help to integrate these domains and disciplines to leverage and apply their interdependencies to attain an optimal design. Via this process domain interests can be integrated to perform effective HSI through trade-offs and collaboration. This provides a common basis upon which to make knowledgeable decisions. Finally, HSI must be considered early in the requirements development phase of system design and acquisition. This will provide the best opportunity to maximize return on investment (ROI) and system performance. HSI requirements must be developed in conjunction with capability ]based requirements generation through functional. HSI requirements will drive HSI metrics and embed HSI issues within the system design. After a system is designed, implementation of HSI oversights can be very expensive. An HSI program should be included as an integral part of a total system approach to vehicle and habitat development. This would include, but not limited to, workstation design, D&C development, volumetric analysis, training, operations, and human -robotic interaction. HSI is a necessary process for Human Space Flight programs to meet the Agency Human ]System standards and thus mitigate human risks to acceptable levels. NASA has been involved in HSI planning, procedures development, process, and implementation for many years, and has been building several internal and publicly accessible products to facilitate HSI fs inclusion in the NASA Systems Engineering Lifecycle. Some of these products include: NASA STD 3001 Volumes 1 and 2, Human Integration Design Handbook, NASA HSI Implementation Plan, NASA HSI Implementation Plan Templates, NASA HSI Implementation Handbook, and a 2 ]hour short course on HSI delivered as part of the NASA Space and Life Sciences Directorate Academy. These products have been created leveraging industry best practices and lessons learned from other Federal Government agencies.

MPACT Fast Neutron Multiplicity System Prototype Development  

Energy Technology Data Exchange (ETDEWEB)

This document serves as both an FY2103 End-of-Year and End-of-Project report on efforts that resulted in the design of a prototype fast neutron multiplicity counter leveraged upon the findings of previous project efforts. The prototype design includes 32 liquid scintillator detectors with cubic volumes 7.62 cm in dimension configured into 4 stacked rings of 8 detectors. Detector signal collection for the system is handled with a pair of Struck Innovative Systeme 16-channel digitizers controlled by in-house developed software with built-in multiplicity analysis algorithms. 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.

Development of DUMAS data processing system  

International Nuclear Information System (INIS)

In the field of nuclear experiments, the speed-up of data processing has been required recently along with the increase of the amount of data per event or the rate of event occurrence per unit time. In the DUMAS project of RCNP, the development of data processing system has been required, which can perform the high speed transfer and processing. The system should transfer the data of 5 multiwire proportional counters and other counters from the laboratory to the counting room at the rate of 1000 events every second, and also should perform considerably complex processes such as histogramming, particle identification, calculation of various polarizations as well as dumping to the secondary memory in the counting room. Furthermore, easy start-up, adjustment, inspection and maintenance and non-special hardware and software should be considered. A system presently being investigated for satisfying the above requirements is described. The main points are as follows: to employ CAMAC system for the interface with readout circuit, to transfer data between the laboratory and the counting room by converting the byte-serial transfer to the bit-serial optical fiber communication, and to unify the data processing computers to the PDP-11 family by connecting two miniature computers. Development of such a data processing system seems to be useful as an preparatory research for the development of NUMATRON measuring instruments. (Wakatsuki, Y.)

Development, primacy, and systems of cities.  

Science.gov (United States)

The relationship between the evolutionary changes in the city size distribution of nationally defined urban systems and the process of socioeconomic development is examined. Attention is directed to the problems of defining and measuring changes in city size distributions, using the results to test empirically the relationship of such changes to the development process. Existing theoretical structures and empirical generalizations which have tried to explain or to describe, respectively, the hierarchical relationships of cities are represented by central place theory and rank size relationships. The problem is not that deviations exist but that an adequate definition is lacking of urban systems on the 1 hand, and a universal measure of city size distribution, which could be applied to any system irrespective of its level of development, on the other. The problem of measuring changes in city size distributions is further compounded by the lack of sufficient reliable information about different systems of cities for the purposes of empirical comparative analysis. Changes in city size distributions have thus far been viewed largely within the framework of classic equilibrium theory. A more differentiated continuum of the development process should replace the bioplar continuum of underdeveloped developed countries in relating changes in city size distribution with development. Implicit in this distinction is the view that processes which influence spatial organization during the early formative stages of development are inherently different from those operating during the more advanced stages. 2 approaches were used to examine the relationship between national levels of development and primacy: a comparative analysis of a large number of countries at a given point in time; and a historical analysis of a limited sample of 2 advanced countries, the US and Great Britain. The 75 countries included in this study cover a wide range of characteristics. The study found a significant association between the degree of primacy of distributions of cities and their socioeconomic level of development; and the form of the primacy curve (or its evolution with development) seemed to follow a consistent pattern in which the peak of primacy obtained during the stages of socioeconomic transition with countries being less primate in either direction from that peak. This pattern is the result of 2 reverse influences of the development process on the spatial structure of countries--centralization and concentration beginning with the rise of cities and a decentralization and spread effect accompanying the increasing influence and importance of the periphery and structural changes in the pattern of authority.

Research and Development Management System (RDMS)  

International Nuclear Information System (INIS)

Research and Development (R and D) is a main activity carried out at the Malaysian Nuclear Agency particularly in the physical science and nuclear field. The R and D activity that is carried out needs to be managed more efficiently and systematically. Until now all research management activities are carried out manually or semi electronically, beginning from filling in application forms to when the project is completed. Therefore a computerized system is needed in order to manage and monitor R and D projects. The R and D system is capable of giving access information concerning R and D projects which are carried out to users inside and outside the agency. The R and D management system (RDMS) can increase the capability of the Malaysian Nuclear Agency in managing, researching and developing, innovating and inventing technology as well as commercializing the R and D produced.

Development of a Universal Waste Management System  

Science.gov (United States)

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.

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)

Development of vehicle intelligent monitoring system (VIMS)  

Science.gov (United States)

In an urban highway network system such as Tokyo Metropolitan Expressway, to detect conditions of road pavement and expansion joints is a very important issue. Although accurate surface condition can be captured by using a road profiler system, the operating cost is expensive and development of a simpler and more inexpensive system is really needed to reduce monitoring cost. "Vehicle Intelligent Monitoring System (VIMS)" developed for this purpose is described in this paper. An accelerometer and GPS are installed to an ordinary road patrol car. GPS together with a PC computer are used to measure the road surface condition and to identify the location of the vehicle, respectively. Dynamic response of the vehicle is used as a measure of the road pavements surface condition as well as the expansion joints. A prototype of VIMS is installed to a motor car and measurement is made at the actual roads. Accuracy of measuring result and effectiveness of this system are demonstrated; the outline of the system and some of the measurement results are reported herein.

Development of Intellectual Reactor Design System: IRDS  

International Nuclear Information System (INIS)

In the frame of the new theme 'Study of analysis method of new nuclear power systems' admitted in our Reactor system laboratory since FY 1988, a program to develop the Intellectual Reactor Design System (IRDS) in the same spirit as ADES has been established. This report describes the activities related to IRDS performed in FY 1989. One of major activities is drafting IRDS. It reflects the conclusion of the STA ADES committee. The essence is to construct a modular system under the object-oriented programming environment to provide a conversational tool for feasibility study and conceptual design. Along the draft the following items were executed in the FY. For the realization of the conversational tool, a tool for input data generation by an object-oriented programming and another tool like CAD for geometry input data generation by a conversational processing of figures on display were examined. Upon the study how to construct the object-oriented data base, the class and frame structures of the design data base were drafted. As components of the modular system, programming of a neutronics and a thermohydraulics module for feasibility study was started. Also a structure analysis code was studied for conversion. In the coming FY, the computer system which has been composed by a FACOM host machine and terminals or isolated PCs will be exchanged by a SUN work-station linked with the host machine and PCs by an ETHER network. Under the suitable environment, the development of IRDS will be promoted. (author)

System for Anomaly and Failure Detection (SAFD) system development  

Science.gov (United States)

This task specified developing the hardware and software necessary to implement the System for Anomaly and Failure Detection (SAFD) algorithm, developed under Technology Test Bed (TTB) Task 21, on the TTB engine stand. This effort involved building two units; one unit to be installed in the Block II Space Shuttle Main Engine (SSME) Hardware Simulation Lab (HSL) at Marshall Space Flight Center (MSFC), and one unit to be installed at the TTB engine stand. Rocketdyne personnel from the HSL performed the task. The 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 failure 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 condition.

Development of a digital mammography system  

International Nuclear Information System (INIS)

A digital breast imaging system is under development to provide improved detectability of breast cancer. In previous work, the limitations of screen-film mammography were studied using both theoretical and experimental techniques. Important limitations were found in both the acquisition and the display components of imaging. These have been addressed in the design of a scanned-projection digital mammography system. A high resolution x-ray image intensifier (XRII), optically coupled to a self-scanned linear photodiode array, is used to record the image. Pre- and post-patient collimation virtually eliminates scattered radiation and veiling glare of the XRII with only a 20% increase in dose due to penumbra. Geometric magnification of 1.6 times is employed to achieve limiting spatial resolution of 7 lp/mm. For low-contrast objects as small as 0.1 mm in diameter, the digital system is capable of producing images with higher contrast and signal-to-noise ratio than optimally-exposed conventional film-screen mammography systems. Greater latitude is obtainable on the digital system because of its wide dynamic range and linearity. The slit system is limited due to long image acquisition times, and poor quantum efficiency. This motivated the authors' current work on a slot beam digital mammography system which is based on a fiber-optic x-ray detector. Preliminary results of this system are presented

Development of an Integrated Distribution Management System  

Energy Technology Data Exchange (ETDEWEB)

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.

Korea Operational Oceanographic System (KOOS) is a research project funded by the Minister of Land, Transport and Maritime Affairs (MLTM) in Korea and the goal of this project is to develop an integrated operational oceanographic system that will provide nowcasts and forecasts of ocean information around Korean Peninsula to support marine activities for governmental agencies and to mitigate coastal disasters such as storm surge, oil spill, and search and rescue. Since August 2009, KIOST has been leading the project to develop KOOS, which consists of three parts, 1) observing systems, 2) numerical modeling with data management and skill assessment, and 3) practical application systems. In KOOS about 190 real-time coastal/ocean observing platforms such as tidal stations, buoys, off-shore research stations and satellites from various agencies, KIOST, KHOA (Korea Hydrographic and Oceanographic Administration), NFRDI (National Fisheries Research & Development Institute), and KMA (Korea Meteorological Administration) have been used for input data as well as calibration and validation for numerical models. With observing networks, various atmospheric models and ocean models have been set-up and tested. KOOS enables us to forecast tides, waves, storm surges, currents as well as temperature and salinity for 72-hour time period in two time a day. The performance of numerical models is evaluated by the skill assessment system. For practical purposes, KOOS has various application systems such as storm surge, search and rescues, oil spill, and ports and channel prediction system. All ocean information in KOOS is to be presented via web-based GIS, which is an effective tool that is helpful to decision-makers.

EXPERT SYSTEMS - DEVELOPMENT OF AGRICULTURAL INSURANCE TOOL  

Directory of Open Access Journals (Sweden)

Full Text Available Because of the fact that specialty agricultural assistance is not always available when the farmers need it, we identified expert systems as a strong instrument with an extended potential in agriculture. This started to grow in scale recently, including all socially-economic activity fields, having the role of collecting data regarding different aspects from human experts with the purpose of assisting the user in the necessary steps for solving problems, at the performance level of the expert, making his acquired knowledge and experience available. We opted for a general presentation of the expert systems as well as their necessity, because, the solution to develop the agricultural system can come from artificial intelligence by implementing the expert systems in the field of agricultural insurance, promoting existing insurance products, farmers finding options in depending on their necessities and possibilities. The objective of this article consists of collecting data about different aspects about specific areas of interest of agricultural insurance, preparing the database, a conceptual presentation of a pilot version which will become constantly richer depending on the answers received from agricultural producers, with the clearest exposure of knowledgebase possible. We can justify picking this theme with the fact that even while agricultural insurance plays a very important role in agricultural development, the registered result got from them are modest, reason why solutions need to be found in the scope of developing the agricultural sector. The importance of this consists in the proposal of an immediate viable solution to correspond with the current necessities of agricultural producers and in the proposal of an innovative solution, namely the implementation of expert system in agricultural insurance as a way of promoting insurance products. Our research, even though it treats the subject at an conceptual level, it wants to undertake an attempt to present the necessity and importance of implementing expert systems in agricultural insurance as a solution of development of the Romanian agricultural sector since insurance play an important role in the stimulation of investments in agriculture and in the stabilization of agricultural producers incomes. The results of the study, at a conceptual level, confirms the necessity of aplying expert systems in agricultural insurance because of the benefits which would be created (informing agricultural producers about the existence and importance of agricultural insurance, the development of the insurance market which would lead to the development of agriculture, creation of new insurance products adapted to the needs of the farmers.

Sensor Development for PEM Fuel Cell Systems  

Energy Technology Data Exchange (ETDEWEB)

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.

Phosphorylation of microtubule-binding protein Hec1 by mitotic kinase Aurora B specifies spindle checkpoint kinase Mps1 signaling at the kinetochore.  

Science.gov (United States)

The spindle assembly checkpoint (SAC) is a quality control device to ensure accurate chromosome attachment to spindle microtubule for equal segregation of sister chromatid. Aurora B is essential for SAC function by sensing chromosome bi-orientation via spatial regulation of kinetochore substrates. However, it has remained elusive as to how Aurora B couples kinetochore-microtubule attachment to SAC signaling. Here, we show that Hec1 interacts with Mps1 and specifies its kinetochore localization via its calponin homology (CH) domain and N-terminal 80 amino acids. Interestingly, phosphorylation of the Hec1 by Aurora B weakens its interaction with microtubules but promotes Hec1 binding to Mps1. Significantly, the temporal regulation of Hec1 phosphorylation orchestrates kinetochore-microtubule attachment and Mps1 loading to the kinetochore. Persistent expression of phosphomimetic Hec1 mutant induces a hyperactivation of SAC, suggesting that phosphorylation-elicited Hec1 conformational change is used as a switch to orchestrate SAC activation to concurrent destabilization of aberrant kinetochore attachment. Taken together, these results define a novel role for Aurora B-Hec1-Mps1 signaling axis in governing accurate chromosome segregation in mitosis. PMID:24187132

Development of industrial variant specification systems  

DEFF Research Database (Denmark)

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: â?¢ Define and describe the variant specification system. â?¢ Create a procedure for the development of variant specification systems. â?¢ Create concepts, methods and tools to support the analysis and determination of the variant specification task. â?¢ Identify solution elements and structural variables to be used in the design of variant specification systems. The thesis presents a â??top-downâ? 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 â??focusâ? 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.

Space Launch System Accelerated Booster Development Cycle  

Science.gov (United States)

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.

Development of Carbon Dioxide Removal Systems for Advanced Exploration Systems  

Science.gov (United States)

"NASA's Advanced Exploration Systems (AES) program is pioneering new approaches for rapidly developing prototype systems, demonstrating key capabilities, and validating operational concepts for future human missions beyond Earth orbit" (NASA 2012). These forays beyond the confines of earth's gravity will place unprecedented demands on launch systems. They must not only blast out of earth's gravity well as during the Apollo moon missions, but also launch the supplies needed to sustain a crew over longer periods for exploration missions beyond earth's moon. Thus all spacecraft systems, including those for the separation of metabolic carbon dioxide and water from a crewed vehicle, must be minimized with respect to mass, power, and volume. Emphasis is also placed on system robustness both to minimize replacement parts and ensure crew safety when a quick return to earth is not possible. Current efforts are focused on improving the current state-of-the-art systems utilizing fixed beds of sorbent pellets by seeking more robust pelletized sorbents, evaluating structured sorbents, and examining alternate bed configurations to improve system efficiency and reliability. These development efforts combine testing of sub-scale systems and multi-physics computer simulations to evaluate candidate approaches, select the best performing options, and optimize the configuration of the selected approach, which is then implemented in a full-scale integrated atmosphere revitalization test. This paper describes the carbon dioxide (CO2) removal hardware design and sorbent screening and characterization effort in support of the Atmosphere Resource Recovery and Environmental Monitoring (ARREM) project within the AES program. A companion paper discusses development of atmosphere revitalization models and simulations for this project.

Remote viewing system development in BNFL  

Energy Technology Data Exchange (ETDEWEB)

The application of imaging systems to BNFL`s plants is primarily provided by the Company`s Engineering Group. Many systems have been developed for active service and several new developments are currently in an advanced stage of implementation. BNFL has acquired extensive experience of remote viewing from a series of projects undertaken for the Sellafield site in West Cumbria. Applications vary in size and complexity, from simple identification of bar-codes to more complex schemes for remotely storing UO{sub 3} drums. Some are high speed and highly repetitive, whereas others are low speed but require high precision. In this paper the authors shall outline a selection of current applications. (Author).

Stirling Convertor System Dynamic Model Developed  

Science.gov (United States)

Free-piston Stirling convertors are being developed for potential use on NASA exploration missions. In support of this effort, the NASA Glenn Research Center has developed the Stirling convertor System Dynamic Model (SDM). The SDM models the Stirling cycle thermodynamics; heat flow; gas, mechanical, and mounting dynamics; the linear alternator; and the controller. The SDM s scope extends from the thermal energy input to thermal, mechanical, and electrical energy output, allowing one to study complex system interactions among subsystems. Thermal, mechanical, fluid, magnetic, and electrical subsystems can be studied in one model. The SDM is a nonlinear time-domain model containing sub-cycle dynamics, which simulates transient and dynamic phenomena that other models cannot. The entire range of convertor operation is modeled, from startup to full-power conditions.

Energy Technology Data Exchange (ETDEWEB)

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), {mu}XL and Personal Computer (PC). WS is used for collection of operation data. {mu}XL is used for cooling system control and PC is used for operators` support. All of the program applications used in WS, {mu}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.

Development of gap switch monitor system  

International Nuclear Information System (INIS)

In order to keep the performance of pulsed power source consisting of many capacitors, switches connected in parallel with the load must be operated as nearly simultaneously as possible (the low distribution time). Monitoring the starting condition of each switches makes it easy to find and repair the malfunctioned switches. As a result, the reliability of bank system is expected to be fairly improved. A switch monitor system which has the above functions is developed and installed to the plasma experimental device TPE-2. The system consists of 312 channels of signal detector sections, a display section and a data acquision and processing section. The distribution of switching time (jitter) can be checked with a sensitivity of 100 ns which is necessary for the reappearance of power system. Signals from the detectors to the display section and GP-IB communication between the display section and the data processing section are optically connected to diminish electromagnetic noise. The reliability of power supply system of TPE-2 is significantly improved by use of the monitor system. (author)

Development of 2-loop feedwater control system  

International Nuclear Information System (INIS)

A 2-loop feedwater control system has been developed for automatic transfer control of the reactor feed pumps (RFP's) in BWR plants. This system consists of a master level controller and sub-loop flow controllers for each of the RFP's. Control characteristics of the 2-loop control system were investigated using a dynamic analysis code for the condensate feedwater system. Although the RFP system has a hydraulic coupling effect, the flow control loops become stable by setting adequate controller gains in the sub-loop flow controllers. The control characteristics in the major loop were modified in their initial response to level setpoint change by using a lead/lag compensator. Moreover, reactor core cooling was protected sufficiently during the transient in a trip of a turbine driven RFP. From simulation results of the transfer controls from the motor driven RFP to turbine driven RFP, it was ascertained that the 2-loop control system has such advantages as shorter completion time and superior controllability against ON-OFF action of a RFP recirculation valve during transfer control.

Health care system reform in developing countries  

Directory of Open Access Journals (Sweden)

Full Text Available This article proposes a critical but non-systematic review of recent health care system reforms in developing countries. The literature reports mixed results as to whether reforms improve the financial protection of the poor or not. We discuss the reasons for these differences by comparing three representative countries: Mexico, Vietnam, and China. First, the design of the health care system reform, as well as the summary of its evaluation, is briefly described for each country. Then, the discussion is developed along two lines: policy design and evaluation methodology. The review suggests that i background differences, such as social development, poverty level, and population health should be considered when taking other countries as a model; ii although demand-side reforms can be improved, more attention should be paid to supply-side reforms; and iii the findings of empirical evaluation might be biased due to the evaluation design, the choice of outcome, data quality, and evaluation methodology, which should be borne in mind when designing health care system reforms.

Development of an automated handwriting analysis system  

Directory of Open Access Journals (Sweden)

Full Text Available In the present study a method has been proposed for the behavioral prediction of a person through automated handwriting analysis. The present work identifies the psychological traits in the writing namely size, slant and pressure, baseline, number of breaks, margins, speed of writing and spacing between the words. The handwriting is analyzed through Image Processing in MATLAB. The behavioral pattern of the person is predicted from the above traits of the handwriting. The developed system identifies handwriting closely which may not be possible for a graphologist. It is real time and involves less image preprocessing. The proposed system is calibrated with manual analysis. The results obtained through the system are in good agreement to more than 80 percent of the cases with ideal manual analysis.

Development of portable superconducting bulk magnet system  

International Nuclear Information System (INIS)

A magnetic drug delivery system (MDDS) has recently been developed enabling magnetic seeded drugs to be navigated around the diseased parts of the human body. To improve the magnetic drug delivery performance, a portable superconducting bulk magnet system with strong magnetic fields has also been developed. This magnet system primarily consists of small bulk high-temperature superconductors and a compact Stirling-cycle cryocooler. The materials used in the high-temperature superconductors are rare earth 123 single domain compounds (GdBaCuO). The main body of the magnet is 9.5 kg and 740 mm in length. In this study, a bulk magnet was successfully activated using field-cooling magnetization under a superconducting solenoid magnet. The magnetic flux densities at the surface of the vacuum chambers that contain the bulk magnets reached 5.07 T and 6.76 T under the static fields of 6 T and 10 T, respectively. We clarified that the magnetic gradient was approximately 10 T/m at a position 50 mm from the surface of the vacuum chambers. This operating bulk magnet system is portable and can be easily transported via car over long distances. (author)

The Monterey Ocean Observing System Development Program  

Science.gov (United States)

The Monterey Bay Aquarium Research Institute (MBARI) has a major development program underway to design, build, test and apply technology suitable to deep ocean observatories. The Monterey Ocean Observing System (MOOS) program is designed to form a large-scale instrument network that provides generic interfaces, intelligent instrument support, data archiving and near-real-time interaction for observatory experiments. The MOOS mooring system is designed as a portable surface mooring based seafloor observatory that provides data and power connections to both seafloor and ocean surface instruments through a specialty anchor cable. The surface mooring collects solar and wind energy for powering instruments and transmits data to shore-side researchers using a satellite communications modem. The use of a high modulus anchor cable to reach seafloor instrument networks is a high-risk development effort that is critical for the overall success of the portable observatory concept. An aggressive field test program off the California coast is underway to improve anchor cable constructions as well as end-to-end test overall system design. The overall MOOS observatory systems view is presented and the results of our field tests completed to date are summarized.

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)

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

Energy Technology Data Exchange (ETDEWEB)

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)

Developments in dry low emissions systems  

Energy Technology Data Exchange (ETDEWEB)

Ever restrictive emissions regulations have a big impact on the production of industrial gas turbines. Solar Turbines Inc. believes that in the long term, clean combustion is more cost effective than exhaust gas cleanup. Therefore, it developed a low emissions combustor called SoLoNOx. The authors described the development process from dry lean-premixed (DLE) combustion to the characteristics of the combustor, followed by the fuel injectors, fuel circuits and the maintenance of product stability. They also examined other combustion technologies like advanced combustor liners, augmented backside-cooled liners, ceramic combustor liners, variable geometry systems and catalytic combustion. Even if this first generation low emission combustor turned out to be a great success, emissions regulations are constantly changing and becoming more stringent. Further research and development is required to meet the new constraints imposed on emissions. 9 refs., 1 tab., 18 figs.

Implementing Life Cycle Assessment in systems development.  

DEFF Research Database (Denmark)

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.

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)

Lunar Surface Systems Supportability Technology Development Roadmap  

Science.gov (United States)

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.

The Mediterranean Forecasting System: recent developments  

Science.gov (United States)

Recent developments of the Mediterranean Monitoring and Forecasting Centre of the EU-Copernicus marine service, the Mediterranean Forecasting System (MFS), are presented. MFS provides forecast, analysis and reanalysis for the physical and biogeochemical parameters of the Mediterranean Sea. The different components of the system are continuously updated in order to provide to the users the best available product. This work is focus on the physical component of the system. The physical core of MFS is composed by an ocean general circulation model (NEMO) coupled with a spectral wave model (Wave Watch-III). The NEMO model provides to WW-III surface currents and SST fields, while WW-III returns back to NEMO the neutral component of the surface drag coefficient. Satellite Sea Level Anomaly observations and in-situ T & S vertical profiles are assimilated into this system using a variational assimilation scheme based on 3DVAR (Dobricic, 2008) . Sensitive experiments have been performed in order to assess the impact of the assimilation of the latest available SLA missions, Altika and Cryosat together with the long term available mission of Jason2. The results show a significant improvement of the MFS skill due to the multi-mission along track assimilation. The primitive equations module has been recently upgraded with the introduction of the atmospheric pressure term and a new, explicit, numerical scheme has been adopted to solve the barotropic component of the equations of motion. The SLA satellite observations for data assimilation have been consequently modified in order to account for the new atmospheric pressure term introduced in the equations. This new system has been evaluated using tide gauge coastal buoys and the satellite along track data. The quality of the SSH has improved significantly while a minor impact has been observed on the other state variables (temperature, salinity and currents). Experiments with a higher resolution NWP (numerical weather prediction) forcing provided by the COSMO-MED system (provided by the Italian Meteorological Office), have been performed and a pre-operational 3-day forecast production system has been developed. The comparison between this system and the official one forced by the ECMWF NWP data will be discussed.

EU developments of the ITER ECRH system  

Energy Technology Data Exchange (ETDEWEB)

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.

New developments of the GANIL Control System  

Energy Technology Data Exchange (ETDEWEB)

Since the 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. CAMAC is the digital transmission standard adopted to interface the processors to the GANIL facilities. In order to cope with the growing needs of the accelerator operation, many developments of the Control System have been carried out during the last years or are underway. After a brief description of the GANIL Control System, this paper describes the major improvements undertaken in four main directions: a) Upgrading the Control Computer. The minicomputer MITRA 125 will be replaced by a faster one equipped with much larger memories and disk capabilities. b) Introducing more powerful local intelligence. An autonomous CAMAC Controller called DIVA 68C using the 68000 microprocessor 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) Improving the human-machine interface with the use of color graphic terminals. d) Meeting the requirements for the coming second injector. For this purpose, a fully equipped auxiliary console is being installed near the main console for operation by summer 1985.

Flammability test for sunglasses: developing a system  

Science.gov (United States)

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.

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

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

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

Developing GP monitoring systems guided by a soft systems approach.  

Science.gov (United States)

This paper describes a selected aspect of a research project concerned with 'contracts and competition' in the recently reformed National Health Service. The particular feature highlighted in this paper is the central role played by the general practitioners in the health service as principal sources of the demands made on provider units (particularly hospitals) and, hence, critical determinants of volumes and costs in contracting. A practical outcome of the research has been the development of GP monitoring systems to be used by provider units particularly in the context of marketing-led referral expectations. The approach used to highlight areas of potential GP contract management and monitoring improvements has been a development of soft systems methodology. PMID:10153274

Solid-vapor adsorption refrigeration system development  

Science.gov (United States)

The study describes the development of heat-activated industrial refrigeration systems using ammoniated complex compound sorption media. The focus was on single-stage cycles for low temperature (+20 F and below) refrigeration. Compared to vapor compression refrigeration, these cycles have the advantages of lower operating energy costs, reduction of peak electrical demand and associated demand charges, and reduced maintenance costs due to replacement of the compressor with solid-state sorbers. In many cases, particularly for refrigeration at -40 F and below, complex compound sorption cycles also have the potential for lower first cost than conventional electrically driven refrigeration systems. Technical issues addressed included the following: economic optimization of sorber design, demonstration of cyclic stability of the sorption reactions, construction material compatibility, and reactor scale-up. Sorption reactions for refrigeration at -40 and -70 F were demonstrated. Optimum heat exchanger configuration, complex compound loading, and cycle time were determined.

The development of a neurosurgical navigation system  

International Nuclear Information System (INIS)

A Computer Assisted Neurosurgical Navigation System (CANS Navigator) has been developed, which assists neurosurgeons in surgery by utilizing images from highly advanced medical imaging devices. During a surgical procedure, the positional and directional information about the surgical, tools can be confirmed by observing their location on the CT or MR images on the CRT monitor. Applying magnetic field technology to position measurement, the position sensor attached to the surgical tool can be made small and light. As a result, no interference occurs with the surgical procedure. Performed on important fine vessels and nerves, neurosurgery requires precision techniques often lasting many hours. Therefore, the surgeons bear great loads physically and psychologically. Because understanding the location of the diseased part and the various organs can be made easy, the use of this system reduces the workload on surgeons and helps effect more accurate and safer surgery.

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

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

Mobile Systems Development: An Empirical Study  

DEFF Research Database (Denmark)

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.

Development of NRU reflector wall inspection system  

Energy Technology Data Exchange (ETDEWEB)

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)

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)

Time fractional development of quantum systems  

Science.gov (United States)

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 ?, which is a measure of the fractality of time. In the case ?=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 ? is relevant to time. It is understood that the fractionalization of time gives rise to energy fluctuations of the quantum (nano) systems.

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.

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

Japan has effectively and efficiently accumulated technologies required for human space activities through its participation in the International Space Station (ISS) program. After the completion of the ISS program, the main arena of human space activities could move from low- Earth orbit to the Moon in the future. In preparation for such development, JAXA considers a future "international human lunar base" that might be developed as the place where Japan could fully utilize, maintain and further develop its capability for conducting human space activities. Since the moon is a test-bed for Mars, permanent lunar bases are a logical outgrowth of initial lunar exploration. For brief visits, the lunar base requires only stored oxygen and water, but a permanent lunar base must recycle oxygen and water to reduce transportation costs. This kind activities will give a great suggestion to sustainable society. A conceptual model of a life support system using physicochemical treatment to circulate the material has been designed. This paper describes test results of the significant design features and preliminary test results of the oxygen production system. The 0.04-0.2

Development of novel emission tomography system  

Science.gov (United States)

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, flexi
