Sample records for chlorpropham pc code

  1. PC-Reactor-core transient simulation code

    International Nuclear Information System (INIS)

    PC-REATOR, a reactor core transient simulation code has been developed for the real-time operator training on a IBM-PC microcomputer. The program presents capabilities for on-line exchange of the operating parameters during the transient simulation, by friendly keyboard instructions. The model is based on the point-kinetics approximation, with 2 delayed neutron percursors and up to 11 decay power generating groups. (author)

  2. HOTSPOT Health Physics codes for the PC

    International Nuclear Information System (INIS)

    The HOTSPOT Health Physics codes were created to provide Health Physics personnel with a fast, field-portable calculation tool for evaluating accidents involving radioactive materials. HOTSPOT codes are a first-order approximation of the radiation effects associated with the atmospheric release of radioactive materials. HOTSPOT programs are reasonably accurate for a timely initial assessment. More importantly, HOTSPOT codes produce a consistent output for the same input assumptions and minimize the probability of errors associated with reading a graph incorrectly or scaling a universal nomogram during an emergency. The HOTSPOT codes are designed for short-term (less than 24 hours) release durations. Users requiring radiological release consequences for release scenarios over a longer time period, e.g., annual windrose data, are directed to such long-term models as CAPP88-PC (Parks, 1992). Users requiring more sophisticated modeling capabilities, e.g., complex terrain; multi-location real-time wind field data; etc., are directed to such capabilities as the Department of Energy's ARAC computer codes (Sullivan, 1993). Four general programs -- Plume, Explosion, Fire, and Resuspension -- calculate a downwind assessment following the release of radioactive material resulting from a continuous or puff release, explosive release, fuel fire, or an area contamination event. Other programs deal with the release of plutonium, uranium, and tritium to expedite an initial assessment of accidents involving nuclear weapons. Additional programs estimate the dose commitment from the inhalation of any one of the radionuclides listed in the database of radionuclides; calibrate a radiation survey instrument for ground-survey measurements; and screen plutonium uptake in the lung (see FIDLER Calibration and LUNG Screening sections)

  3. Development of PC version code system for radiation dose estimation

    International Nuclear Information System (INIS)

    Since a direct access from a radiation work site to a main frame computer is usually difficult, evaluation of radiation sources and/or doses are often carried out by handcalculations with less accuracy. So considering a recent remarkable progress of PC (Personal computer), we have developed an interactive code system of PC version to calculate dose equivalent values with high accuracy. It consists of a radiation source calculation code ORIGEN-2 and point kernel shielding calculation codes, QAD-CGGP2 and G33-GP2. With the present system, you can easily obtain dose equivalent values at any detector point starting from radiation source estimation. Validity of these codes have been verified individually on a main frame computer through various benchmark calculations. Thus we verified the present PC version system by comparing the PC calculations with those using a main frame computer. Excellent agreement was obtained between them. (author)

  7. Application of an integrated PC-based neutronics code system to criticality safety

    International Nuclear Information System (INIS)

    An integrated system of neutronics and radiation transport software suitable for operation in an IBM PC-class environment has been under development at the Idaho National Engineering Laboratory (INEL) for the past four years. Nuclear cross-section data and resonance parameters are preprocessed from the Version 5 Evaluated Nuclear Data Files (ENDF/B-V) and supplied in a form suitable for use in a PC-based spectrum calculation and cross-section generation module. The cross-section module of the PC-based code system produces application-specific data libraries that can be used in various PC-based neutron transport and diffusion theory code modules. Some of the modules in the system are straightforward conversions of existing codes with a few improvements to allow more effective operation in the PC environment while other modules were specifically written for the PC code system. Four modules within the system are particularly useful for criticality safety applications: COMBINE/PC, a portable ENDF/B Version 5 neutron spectrum and cross-section generation program; KENO5A/PC, a three-dimensional Monte Carlo criticality module; ANISN/PC, a one-dimensional, discrete ordinates transport theory code; and DORT/PC, a two-dimensional, discrete ordinates transport theory code. A description of the codes and methods used in the analysis and the results of the benchmark critical experiments are presented in this paper. In general, excellent agreement was found between calculated and experimental results. 19 refs., 1 fig., 3 tabs

  10. Development of a PC code package for the analysis of research and power reactors

    International Nuclear Information System (INIS)

    Computer codes available for performing reactor physics calculations for nuclear research reactors and power reactors are normally suited for running on mainframe computers. With the fast development in speed and memory of the PCs and affordable prices it became feasible to develop PC versions of commonly used codes. The present work performed under an IAEA sponsored research contract has successfully developed a code package for running on a PC. This package includes a cross-section generating code PSU-LEOPARD and 2D and 1D spatial diffusion codes, MCRAC and MCYC 1D. For adapting PSU-LEOPARD for a PC, the binary library has been reorganized to decimal form, upgraded to FORTRAN-77 standard and arrays and subroutines reorganized to conform to PC compiler. Similarly PC version of MCRAC for FORTRAN-77 and 1D code MCYC 1D have been developed. Tests, verification and bench mark results show excellent agreement with the results obtained from mainframe calculations. The execution speeds are also very satisfactory. 12 refs, 4 figs, 3 tabs

    We consider the implementation of a parallel Monte Carlo code for high-performance simulations on PC clusters with MPI. We carry out tests of speedup and efficiency. The code is used for numerical simulations of pure SU(2) lattice gauge theory at very large lattice volumes, in order to study the infrared behavior of gluon and ghost propagators. This problem is directly related to the confinement of quarks and gluons in the physics of strong interactions.

  15. Determination of neutronics parameters of the Ghana MNSR using the diffusion code REBUS-PC

    International Nuclear Information System (INIS)

    Neutronics plays a major role in nuclear reactor analysis and the prediction, operation and safety of nuclear reactors. Neutronics also plays a major role when it comes to coupling of neutronics and thermal hydraulics codes which is the current trend in nuclear engineering. This thesis presents an investigative study into the determination of some neutronics parameters such as cross-section, neutron flux, power peaking factors, control rod, shutdown margin and safety reactivity factor of the Miniature Neutron Source Reactor(MNSR) of Ghana using the diffusion code REBUS-PC. Neutron cross-sections and their group constants were generated by WIMS and the results used as input file for REBUS-PC. The REBUS-PC input deck was modified to cater for control rod insertions and withdrawals and the various neutronics parameters calculated. Comparisons were made of the values of power peaking factors, control rod worth versus axial position, safety reactivity factor, axial neutron flux versus axial distances and shutdown margin determined by REBUS-PC and MCNP-5. An average neutron flux of 1.13 x 1012n cm-2 s-1 was reported which was 13% higher than the experimentally quoted value of 1.0x12n cm-2s -1 when REBUS-PC was used. A k-effective of 1.00426±0.00001 which corresponded to 0.026% higher than the experimental value of 1.0040 ± 0.00000 and an excess reactivity of 4.24 mk which also corresponds to 24% higher than the experimental value of 4.00 mk were determined when REBUS-PC was used for the simulation. A control rod worth value of 6.92 mk was also calculated which corresponded to 8% higher than the experimental value of 7.00 mk, whiles a shutdown margin of 2.68 which also corresponds to 32% higher than the experimental value of 3.00 were calculated. These determined neutronics parameters showed remarkable agreement with experimental data and hence will ensure safe operation of the reactor (GHARR-1). (au)

    Chlorpropham (isopropyl 3-chlorocarbanilate) is a pesticide used to control sprouting of potatoes during long-term storage. The objective of the present study was to establish the total chlorpropham residue balance (residues in unwashed and washed whole tubers, peeled tubers, peels, boiled and pureed tubers, and washing and cooking waters) for two potato varieties after uniform application as a function of storage time under different typical storage conditions (in a basement, storehouse, and refrigerator) in Lithuania. Chlorpropham concentration on washed and unwashed tubers decreased from approximately 15 mg kg(- 1) after storage for 28 d to approximately 9 mg kg(- 1) after storage for 85 d. Peel concentrations decreased from approximately 50 mg kg(- 1) at 5 d after treatment to approximately 20 mg kg(- 1) at 85 d after treatment. The average concentration in the two varieties of peeled tubers in the three storage facilities was 1 mg kg(- 1). Chlorpropham concentrations in the wash water decreased from 3.5 to 1.0 mg L(- 1) when the storage time increased from 28 to 85 d. The cooking water concentration similarly decreased, from > 0.2 mg L(- 1) at 28 d after treatment to > 0.1 mg L(- 1) at 85 d after treatment. The results of this study show that chlorpropham concentrations in tubers under these typical conditions were below the recently revised levels that are acceptable for residues in whole potatoes (30 mg kg(- 1)) and peels (40 mg kg(- 1)). Also, despite fluctuating conditions during storage, chlorpropham treated tubers did not sprout, as compared to untreated tubers, which sprouted. PMID:19089708

  17. Identification and functional characterization of G6PC2 coding variants influencing glycemic traits define an effector transcript at the G6PC2-ABCB11 locus.

    Full Text Available Genome wide association studies (GWAS for fasting glucose (FG and insulin (FI have identified common variant signals which explain 4.8% and 1.2% of trait variance, respectively. It is hypothesized that low-frequency and rare variants could contribute substantially to unexplained genetic variance. To test this, we analyzed exome-array data from up to 33,231 non-diabetic individuals of European ancestry. We found exome-wide significant (P<5×10-7 evidence for two loci not previously highlighted by common variant GWAS: GLP1R (p.Ala316Thr, minor allele frequency (MAF=1.5% influencing FG levels, and URB2 (p.Glu594Val, MAF = 0.1% influencing FI levels. Coding variant associations can highlight potential effector genes at (non-coding GWAS signals. At the G6PC2/ABCB11 locus, we identified multiple coding variants in G6PC2 (p.Val219Leu, p.His177Tyr, and p.Tyr207Ser influencing FG levels, conditionally independent of each other and the non-coding GWAS signal. In vitro assays demonstrate that these associated coding alleles result in reduced protein abundance via proteasomal degradation, establishing G6PC2 as an effector gene at this locus. Reconciliation of single-variant associations and functional effects was only possible when haplotype phase was considered. In contrast to earlier reports suggesting that, paradoxically, glucose-raising alleles at this locus are protective against type 2 diabetes (T2D, the p.Val219Leu G6PC2 variant displayed a modest but directionally consistent association with T2D risk. Coding variant associations for glycemic traits in GWAS signals highlight PCSK1, RREB1, and ZHX3 as likely effector transcripts. These coding variant association signals do not have a major impact on the trait variance explained, but they do provide valuable biological insights.

  18. PC-based criticality code use at an open-quotes isolated siteclose quotes

    International Nuclear Information System (INIS)

    Personal computer (PC)-based codes were used to conduct evaluations for subcriticality of fissile material in staging areas at the Pantex plant. The calculations, whose results were used in safety analysis reports (SARS) and a radiological hazards analysis (RHA), were performed by an individual practitioner located off-site. The Pantex evaluations addressed plutonium-metal components, modeling them as identical generic units. The model is conservative for criticality safety purposes in assuming a spherical shell with increased mass and reduced radius, while the plutonium content is treated as if it is all 239Pu. The computer codes KEN05APC (with 16-group Hansen-Roach cross sections) and MCNP4 (in a package with grouped cross sections) were obtained from the Radiation Shielding Information Center (RSIC). Calculations were performed for arrays of units in various numbers and arrangements with a variety of moderations and reflection conditions and with and without containers

  19. NUSTART: A PC code for NUclear STructure And Radiative Transition analysis and supplementation

    International Nuclear Information System (INIS)

    NUSTART is a computer program for the IBM PC/At. It is designed for use with the nuclear reaction cross-section code STAPLUS, which is a STAPRE-based CRAY computer code that is being developed at Lawrence Livermore National Laboratory. The NUSTART code was developed to handle large sets of discrete nuclear levels and the multipole transitions among these levels; it operates in three modes. The Data File Error Analysis mode analyzes an existing STAPLUS input file containing the levels and their multipole transition branches for a number of physics and/or typographical errors. The Interactive Data File Generation mode allows the user to create input files of discrete levels and their branching fractions in the format required by STAPLUS, even though the user enters the information in the (different) format used by many people in the nuclear structure field. In the Branching Fractions Calculations mode, the discrete nuclear level set is read, and the multipole transitions among the levels are computed under one of two possible assumptions: (1) the levels have no collective character, or (2) the levels are all rotational band heads. Only E1, M1, and E2 transitions are considered, and the respective strength functions may be constants or, in the case of E1 transitions, the strength function may be energy dependent. The first option is used for nuclei closed shells; the bandhead option may be used to vary the E1, M1, and E2 strengths for interband transitions. K-quantum number selection rules may be invoked if desired. 19 refs

  1. Theoretical and user's manual for pc-PRAISE: A probabilistic fracture mechanics computer code for piping reliability analysis

    International Nuclear Information System (INIS)

    The purpose of this document is to collect under one cover and update the documentation related to the PRAISE Computer Code. pc-PRAISE is the most recent version of the code, which is a probabilistic fracture mechanics code that has recently been modified to run on an IBM personal computer to evaluate the reliability of welds in nuclear power plant piping systems. pc-PRAISE was adapted from the PRAISE Computer Code, which was originally developed in 1980--81 by Lawrence Livermore National Laboratory (LLNL) under funding from the US Nuclear Regulatory Commission for assessment of the influence of seismic events on the failure probability of piping in pressurized water reactors. PRAISE is an acronym for Piping Reliability Analysis Including Seismic Events, and has been significantly expanded in recent years to allow consideration of both crack initiation and growth in a variety of piping materials in pressurized and boiling water reactors. PRAISE has a deterministic basis in fracture mechanics. Some of the inputs, such as initial crack size and inspection detection probability, are considered to be random variables, and failure probability versus time for a given weldment is evaluated by Monte Carlo simulation. Complex realistic stress histories can be treated by the code, and sets of random material properties for representative piping materials are built into the code. This document provides a comprehensive summary of the deterministic basis of the code, along with description of statistical distributions of random variables. Code inputs are described and an extensive set of sample problems is provided along with descriptions of representative outputs

  2. Description and validation of ANTEO, an optimised PC code the thermalhydraulic analysis of fuel bundles

    International Nuclear Information System (INIS)

    The paper deals with the description of a Personal Computer oriented subchannel code, devoted to the steady state thermal hydraulic analysis of nuclear reactor fuel bundles. The development of such a code was made possible by two facts: firstly, the increase, in the computing power of the desk machines; secondly, the fact that several years of experience into operate subchannels codes have shown how to simplify many of the physical models without a sensible loss of accuracy. For sake of validation, the developed code was compared with a traditional subchannel code, the COBRA one. The results of the comparison show a very good agreement between the two codes. (author)

    International Nuclear Information System (INIS)

    Research highlights: → Impact of Tehran's reactor and radioisotope laboratory stacks has been studied. → Gaussian Plume Dispersion Model and laboratory analyses were used. → Glass-fiber filters were used in the exclusion area in different direction. → The released radionuclide concentration was calculated by the code and measurements. → Dose calculations best compared to procedures presented in the Regulatory Guide. - Abstract: The amount of released radionuclide from Tehran's research reactor and radioisotope laboratory stacks and their impact have been studied. The aim of this work is to determine the amount and type of radioactive materials and to estimate their risk once they are released into the environment. To perform the above two tasks, CAP88-PC computer code which simulates Gaussian dispersion air transport Plume Model and laboratory analysis of air samples around the site were used. Computer code input data are provided by the Safety Analysis Report and Reactor Annual Reports. Air samples were collected using the filter and sampling pumps and analyzed by gamma spectroscopy counter. Results of computer program showed that the risk of cancer death (lifetime risk) is below the regulatory limit. Results of analysis of available radionuclide in the air samples also showed that concentrations are close to the background and confirm the code results.

  10. PC/FRAM: A code for the nondestructive measurement of the isotopic composition of actinides for safeguards applications

    Sampson, T.E.; Kelley, T.A.

    1996-12-01

    The Nuclear Safeguards Program at the Los Alamos National Laboratory has developed and fielded techniques for the gamma-ray spectrometry measurement of the isotopic composition of plutonium and other actinides for over 20 years, ever since Parker and Reilly first proposed a practical method for the measurement of the arbitrary sample. Their procedures, incorporating internal (to the measured gamma-ray spectrum) or {open_quotes}intrinsic{close_quotes} self-determination of the relative efficiency function of the sample-detector measurement system, are widely applied today. The PC/FRAM code is the most recent and most highly-developed Los Alamos code developed specifically for the nuclear safeguards applications of this technique. We will describe the measurement principles that allow accurate measurements to be taken on samples of arbitrary size, shape, and measurement geometry- and of arbitrary physical and chemical composition-through the use of known nuclear decay data (half-lives and branching intensities). Subsequently, we will describe the analysis methodology, which is driven by an easily edited parameter file that frees the user from dependence on a dedicated programmer for analyses of special cases. This methodology relies on internal gamma-ray peaks from the spectrum under analysis to self-calibrate the unknown spectrum for energy and peak shape (energy dependence of full width at half maximum (FWHM) and tailing parameters). The program uses these parameters to calculate response functions that are fit to the analysis peaks requested in the parameter file. The structure of the code and its Windows 3.1 user interface allows use with equal ease by the experienced spectroscopist or operator-level personnel in a working facility.

    After modulation of sulphation and glucuronidation, the relationship between the changes in metabolism and cytotoxicity of chloropropham (CIPC), a widely used herbicide, was investigated in isolated rat hepatocyte suspensions. Under physiological conditions, CIPC had a cytolytic effect, modified membrane permeability and reduced intracellular ATP level. CIPC was metabolized by hepatocytes mainly into 4-OH chlorpropham sulphate (37%) and glucuronide conjugates (18%). Inhibition of sulphation, by omitting sulphate from the isolation and incubation media, did not affect the cytotoxicity of CIPC, since there was a 2.5-fold compensatory increase in 4-OH CIPC glucuronide. Inhibition of glucuronidation by adding 4 mM D-galactosamine in the incubation medium led to a 66% decrease of glucuronide conjugate and simultaneously to a 32% decrease of sulphate conjugate. In that case, concentrations of free 4-OH CIPC in both hepatocytes and incubation medium were markedly increased, while those of 3-chloroaniline and 3-chloroacetanilide were slightly modified and remained low. This alteration of metabolism was accompanied by modification of cell permeability and reduction in ATP synthesis. The cytolytic effect was due to CIPC itself, whereas the effect on energetic metabolism was attributed to a metabolite. Results demonstrated for the first time a partial inhibition of sulphation by D-galactosamine (4 mM), probably due to the effect of D-galactosamine on intracellular ATP levels. PMID:8588294

  13. Simulation of radiation dose rate distributions around casks in ships and vehicles by using QBF code for PC-9801 computer

    International Nuclear Information System (INIS)

    The main aim of the present report is to show that the behavior of the spatial distribution of the radiation dose rate in a wide region can be easily visualized in various aspects of cask shipment even by personal computers which are very popular today, and that the QBF code system is a useful tool to perform this simulation. A great merit of using this code system is that one can easily analyze, with high reliability, roles of various important factors such as shielding structures and cask positions in the behavior of dose rate distributions.

    International Nuclear Information System (INIS)

    Evaluating the need for and the effectiveness of remedial cleanup at waste sites often includes finding average contaminant concentrations and identifying pockets of contamination called hot spots. The standard tool for calculating the probability of detecting pockets of contamination called hot spots has been the ELIPGRID code of singer and Wickman. The ELIPGRID-PC program has recently made this algorithm available for an IBM reg-sign personal computer (PC) or compatible. A new version of ELIPGRID-PC, incorporating Monte Carlo test results and simple graphics, is herein described. Various examples of how to use the program for both single and multiple hot spot cases are given. The code for an American National Standards Institute C version of the ELIPGRID algorithm is provided, and limitations and further work are noted. This version of ELIPGRID-PC reliably meets the goal of moving Singer's ELIPGRID algorithm to the PC

  1. Metabolism and cytotoxicity of chlorpropham (CIPC) and its essential metabolites in isolated rat hepatocytes during a partial inhibition of sulphation and glucuronidation reactions: a comparative study.

    1998-07-01

    The changes in metabolism and cytotoxicity of chlorpropham (CIPC) and its major metabolites, 4-hydroxychlorpropham (4-OH CIPC), 3-chloroaniline, and 3-chloroacetanilide were investigated in isolated rat hepatocyte suspensions after a partial inhibition of sulphation and glucuronidation and the two reactions combined in an attempt to assess the part of each of them in the enhanced CIPC toxicity observed in vivo after D-galactosamine treatment. With sulphation and glucuronidation effective, CIPC has a cytolytic effect and reduces intracellular ATP and K+ level while 4-OH CIPC has a weak cytolytic effect but modifies ATP and K+ level in a greater extent than CIPC. Inhibition of sulphation does not affect the cytotoxicity of CIPC or 4-OH CIPC because there is a compensatory increase in the amount of 4-OH CIPC glucuronide formed and the level of free 4-OH CIPC always remain low. In contrast, when incubations are carried out with either CIPC or 4-OH CIPC, the presence of D-galactosamine leads to a decrease of glucuronide and sulphate conjugates accompanied, respectively, by a 3.6-fold and 6. 9-fold increase of the free 4-OH CIPC level in the culture medium. This alteration of the metabolism is followed by a marked reduction of ATP synthesis with a concomitant modification of cell permeability. The cytolytic effect is due to CIPC itself, whereas the effect on energy supply was attributed to free 4-OH CIPC. The results demonstrate a combined effect of free 4-OH CIPC and D-galactosamine on intracellular ATP level that could account for the partial inhibition of sulphation. This change in the CIPC metabolism could explain the increased CIPC toxicity observed in vivo after D-galactosamine pretreatment. PMID:9601925

  4. Monte Carlo tests of the ELIPGRID-PC algorithm

    International Nuclear Information System (INIS)

    The standard tool for calculating the probability of detecting pockets of contamination called hot spots has been the ELIPGRID computer code of Singer and Wickman. The ELIPGRID-PC program has recently made this algorithm available for an IBM reg-sign PC. However, no known independent validation of the ELIPGRID algorithm exists. This document describes a Monte Carlo simulation-based validation of a modified version of the ELIPGRID-PC code. The modified ELIPGRID-PC code is shown to match Monte Carlo-calculated hot-spot detection probabilities to within ±0.5% for 319 out of 320 test cases. The one exception, a very thin elliptical hot spot located within a rectangular sampling grid, differed from the Monte Carlo-calculated probability by about 1%. These results provide confidence in the ability of the modified ELIPGRID-PC code to accurately predict hot-spot detection probabilities within an acceptable range of error

  15. On the graphic simulation of severe accidents using IBM PC

    International Nuclear Information System (INIS)

    In this paper some methods of developing a graphical simulation system using IBM PC and MELCOR code were discussed. Most TH codes, which can calculate the severe accident phenomena parameters, are now running on workstations or supercomputers, to meet the complicated calculations. But the recent progress in computer engineering including personal computers make it possible to run TH codes in small microprocessor environments. Therefore we have surveyed some technical aspects in developing a severe accident graphical simulation system using IBM PC and MELCOR code. Especially noticing the complicated calculation results and the difficulties in obtaining continuous data due to the large data size, which are main defects of TH codes, we also surveyed the graphical methods to overcome these problems. The proposed methods are expected to play important roles in developing our graphic simulation system of severe accidents

  16. Conical Nanopore PC Membranes

    International Nuclear Information System (INIS)

    Template synthesis can be considered an alternative to conventional lithography methods. It is one way of providing a panel of nanoscale metallic wires, tubes or organic polymeric devices. Our interest is focused on track-etched membranes produced from swift heavy ions bombardment of polymer films. In comparison with self-assembly of block copolymers, this bottom-up approach has the advantage of being economic, it is not time-consuming and it allows track formation of diverse geometries. Tailoring of the conical nanopore tip opening would have a tremendous impact on sensing domain, as well as on fundamental understanding of perpendicular giant magneto Resistance properties observed in metallic multilayered cylindrical nanowires. By combining low-energy heavy ion beam radiation effects with asymmetric etching, the etching temperature and time can be tuned to prepare conical nanopores of controlled geometry from 0.5 to 1μm at the base to a few nanometers at the top. Asymmetric etching onto PC films was pH-monitored at various temperatures in the range of 65 degree to 80 degree. Fluence impact onto track etch pores was also investigated. The pore shape characterization was achieved by electronic microscopy measurements on membrane surfaces and on electrodeposited nanowires. We have also observed a difference in the conical shape of replicated nanowires. Some showed sting shapes and others displayed shell shapes depending on whether a neutralizing agent was used during etching or not

  18. PC-PRAISE, BWR Piping Reliability Analysis

    International Nuclear Information System (INIS)

    1 - Description of program or function: PC-PRAISE is a probabilistic fracture mechanics computer code developed for IBM or IBM compatible personal computers to estimate probabilities of leak and break in nuclear power plant cooling piping. 2 - Method of solution: PC-PRAISE considers the initiation and/or growth of crack-like defects in piping weldments. The initiation analyses are based on the results of laboratory studies and field observations in austenitic piping material operating under boiling water reactor conditions. The considerable scatter in such results is quantified and incorporated into a probabilistic model. The crack growth analysis is based on (deterministic) fracture mechanics principles, in which some of the inputs (such as initial crack size) are considered to be random variables. Monte Carlo simulation, with stratified sampling on initial crack size, is used to generate weldment reliability results. 3 - Restrictions on the complexity of the problem: There is essentially no limitation with PC-PRAISE but for large number of replications used in the Monte Carlo simulation scheme, computation time may become prohibitive

    1 - Description of program or function: These primitives are the lowest level routines needed to perform super VGA graphics on a PC. A sample main program is included that exercises the primitives. Both Lahey and Microsoft FORTRAN's have graphics libraries. However, the libraries do not support 256 color graphics at resolutions greater than 320x200. The primitives bypass these libraries while still conforming to standard usage of BIOS. The supported graphics modes depend upon the PC graphics card and its memory. Super VGA resolutions of 640x480 and 800x600 have been tested on an ATI VGA Wonder card with 512 K memory and on several 80486 PC's (unknown manufacturers) at retail stores. 2 - Method of solution: Both Lahey and Microsoft primitives depend upon sending the correct parameters to the PC BIOS (basic input output system) as discussed in the references. 3 - Restrictions on the complexity of the problem: The primitives were developed for 256 color VGA applications. It is known, for instance, that some CGA and 16 color VGA video modes will not operate correctly using these primitives. Potential users should try the test program on their PC/video card combination to determine applicability

    The Integrated Composite Analyzer (ICAN) is a computer program designed to carry out a comprehensive linear analysis of multilayered fiber composites. The analysis contains the essential features required to effectively design structural components made from fiber composites. ICAN includes the micromechanical design features of the Intraply Hybrid Composite Design (INHYD) program to predict ply level hygral, thermal, and mechanical properties. The laminate analysis features of the Multilayered Filamentary Composite Analysis (MFCA) program are included to account for interply layer effects. ICAN integrates these and additional features to provide a comprehensive analysis capability for composite structures. Additional features unique to ICAN include the following: 1) ply stress-strain influence coefficients, 2) microstresses and microstrain influence coefficients, 3) concentration factors around a circular hole, 4) calculation of probable delamination locations around a circular hole, 5) Poisson's ratio mismatch details near a straight edge, 6) free-edge stresses, 7) material card input for finite element analysis using NASTRAN (available separately from COSMIC) or MARC, 8) failure loads based on maximum stress criterion, and laminate failure stresses based on first-ply failures and fiber breakage criteria, 9) transverse shear stresses, normal and interlaminar stresses, and 10) durability/fatigue type analyses for thermal as well as mechanical cyclic loads. The code can currently assess degradation due to mechanical and thermal cyclic loads with or without a defect. ICAN includes a dedicated data bank of constituent material properties, and allows the user to build a database of material properties of commonly used fibers and matrices so the user need only specify code names for constituents. Input to ICAN includes constituent material properties (or code names), factors reflecting the fabrication process, and composite geometry. ICAN performs micromechanics

    International Nuclear Information System (INIS)

    Instruments for nuclear signal measurements based on add-on card for a personal computer (PC) are designed often. Then one faces the problem of the addressing of data input/output devices which show an integration level or intelligence that makes the use of several port address indispensable, and these are limited in the PC. The virtual addressing offers the advantage of the occupation of few addresses to accede to many of these devices. The principles of this technique and the appliances of a solution in radiometric in a radiometric card based on programmed logic are discussed in this paper

  8. Versatile PC-logger for radioisotope measurements

    International Nuclear Information System (INIS)

    The logger, a personal computer and software is all to set up a radioisotope measuring system. It may find numerous applications in a wide range of disciplines: kinetics description of flow process in industry, slip velocity measurements in hydrotransport, flow rates evaluation in waste water treatment plants, nucleonic gauges in industry, ect. Readings from up to 4 scintillation detectors, the user has set to log, are stored in regular intervals. The user can set the logger to start and stop logging manually, with keyboard or from a program running on a connected PC. Stored data can be transferred to any computer with RS232 serial interface. The logger works equally well together with conventional PC's and 'lap-tops' for field work. Its internal program is stored in nonvolatile RAM. This makes it possible to upgrade or change the code by just down loading a new one. The logger is internal rechargeable batteries for measuring off-line; they remain as a back-up in case the external supply is disconnected or fails. (author)

    The Stellaris PC (Bausch & Lomb) is a versatile platform that allows surgeons to perform both anterior segment and posterior segment surgeries. It was developed based on the Stellaris microincision cataract surgery system and can therefore perform coaxial or bimanual microincision cataract surgery in combination with posterior segment surgery. Similar to Millenium, its predecessor, the Stellaris PC has an open architecture with modular design that allows products and instruments manufactured by other companies to be used with the system. Vitrectomy can be performed using the traditional 20-gauge system or with microincision 23- or 25-gauge transconjunctival sutureless vitrectomy systems. The special design of the vitreous cutter with increased port area, improved fluidics, and optimized port open time makes the Stellaris PC an efficient system for performing microincision vitrectomy surgery. This article will describe the design, features, and details of various components of the Stellaris PC, including machine controls, entry site alignment trocar/cannula system, fluidics, and high-speed vitreous cutter, as well as its unique illumination system.

  12. Phenomenology of Pc(4380)+, Pc(4450)+ and related states

    International Nuclear Information System (INIS)

    The Pc(4380)+ and Pc(4450)+ states recently discovered at LHCb have masses close to several relevant thresholds, which suggests they can be described in terms of meson-baryon degrees of freedom. This article explores the phenomenology of these states, and their possible partners, from this point of view. Competing models can be distinguished by the masses of the neutral partners which have yet to be observed, and the existence or otherwise of further partners with different isospin, spin, and parity. Future experimental studies in different decay channels can also discriminate among models, using selection rules and algebraic relations among decays. Among the several possible meson-baryon pairs which could be important, one implies that the states are mixtures of isospins 1/2 and 3/2, with characteristic signatures in production and decay. A previous experimental study of a Cabibbo-suppressed decay showed no evidence for the states, and further analysis is required to establish the significance of this non-observation. Several intriguing similarities suggest that Pc(4450)+ is related to the X(3872) meson. (orig.)

  13. User's guide for an interactive fault tree editor, PC-CREFTS

    International Nuclear Information System (INIS)

    To support the core damage frequency evaluation in probabilistic safety assessment (PSA) for nuclear power plants, a personal computer (PC) based level-1 program package named PC-REFT (PC-Based Reliability Analysis with Event Tree and Fault Tree Techniques) is being developed at JAERI. This report provides a user's guide for a fault tree editor, PC-CREFTS, which is a member program of PC-REFT. PC-CREFTS is a PC-based program for editing fault trees interactively and has the following capabilities and features. (1) Interactively constructing/updating fault trees and assigning failure rate data to basic events on a given fault tree : This capability enhances efficiency in building and modifying fault trees. (2) Checking the logical structure of a given fault tree and lack of failure rates for basic events : This capability can eliminate data errors in preparing input data for the fault tree analysis. (3) Creating input data files for the fault tree analysis codes, FTA-J and CUT-TD, which were developed at JAERI and run on a main-frame computer : This capability can reduce manual efforts in preparing input data for these codes. (4) Printing a given fault tree : This capability assists the analyst in documenting the fault tree analysis. In addition, PC-CREFTS gives the user-friendly graphic interface, making it easier for the users to edit the fault tree and to manage the data files. (author)

  15. PC driven integrated vacuum system

    International Nuclear Information System (INIS)

    The monitoring of industrial plants by virtual instrumentation represents the most modern trend in the domain of electronic equipment. The integrated vacuum system presented here has several facilities, including the automated data storing of measurement results on hard disk and providing warning messages for operators when the measured parameters are lower or higher upper than the fixed values. The system can also work stand-alone, receiving the commands from the keyboards placed on his front panel but, when it is included in a automation complex system, a remote control from PC is necessary . Both parts of the system, power supply unit for turbo-molecular pump and the vacuum gage, are controlled by an 80C31 microcontroller. Because this microcontroller has a built-in circuitry for a serial communication, we established a serial communication between the PC and the power supply unit for turbo-molecular pump and the vacuum gage, according to the RS-232 hardware standard. As software, after careful evaluation of several options, we chose to develop a hybrid software packing using two different software development tools: LabVIEW, and assembly language. We chose LabVIEW because it is dedicated to data acquisition and communications, containing libraries for data collection, analysis, display and storage. (authors)

  16. PC based vibration monitoring system

    International Nuclear Information System (INIS)

    Health of large rotating machinery gets reflected in the vibration signature of the rotor and supporting structures and proper recording of these signals and their analysis can give a clear picture of the health of the machine. Using these data and their trending, it is possible to predict an impending trouble in the machine so that preventive action can be taken in time and catastrophic failure can be avoided. Continuous monitoring and analysis can give quick warning and enable operator to take preventive measures. Reactor Control Division, BARC is developing a PC based Vibration monitoring system for turbo generator machinery. The System can acquire 20 vibration signals at a rate of 5000 samples per second and also 15 process signals at a rate of 100 samples/ sec. The software for vibration monitoring system includes acquisition modules, analysis modules and Graphical User Interface module. The acquisition module involves initialization, setting of required parameters and acquiring the data from PC-based data acquisition cards. The acquired raw vibration data is then stored for analysis using various software packages. The display and analysis of acquired data is done in LabVIEW 7.0 where the data is displayed in time as well as frequency domain along with the RMS value of the signal. (author)

    Montelongo, S

    2005-12-16

    The Spectral Instruments (SI) PC104 systems associated with the SI-1000 CCD camera exhibited intermittent power problems during setup, test and operations which called for further evaluation and testing. The SI PC104 System is the interface between the SI-1000 CCD camera and its associated Diagnostic Controller (DC). As such, the SI PC104 must be a reliable, robust system capable of providing consistent performance in various configurations and operating conditions. This SI PC104 system consists of a stackable set of modules designed to meet the PC104+ Industry Standard. The SI PC104 System consists of a CPU module, SI Camera card, Media converter card, Video card and a I/O module. The root cause of power problems was identified as failing solder joints at the LEMO power connector attached to the SI Camera Card. The recommended solution was to provide power to the PC104 system via a PC104+ power supply module configured into the PC104 stack instead of thru the LEMO power connector. Test plans (2) were developed to test SI PC104 performance and identify any outstanding issues noted during extended operations. Test Plan 1 included performance and image acquisition tests. Test Plan 2 verified performance after implementing recommendations. Test Plan 2 also included verifying integrity of system files and driver installation after bootup. Each test plan was implemented to fully test against each set of problems noted. Test Plan presentations and Test Plan results are attached as appendices. Anticipated test results will show successful operation and reliable performance of the SI PC104 system receiving its power via a PC104 power supply module. A SI PC104 Usage Recommendation Memo will be sent out to the SI PC104 User Community. Recommendation memo(s) are attached as appendices.

  19. PC/104 Embedded IOCs at Jefferson Lab

    International Nuclear Information System (INIS)

    Jefferson Lab has developed embedded IOCs based on PC/104 single board computers (SBC) for low level control systems. The PC/104 IOCs run EPICS on top of the RTEMS operating system. Two types of control system configurations are used in different applications, PC/104 SBC with commercial PC/104 I/O cards and PC/104 SBC with custom designed FPGA-based boards. RTEMS was built with CEXP shell to run on the PC/104 SBC. CEXP shell provides the function of dynamic object loading, which is similar to the widely used VxWorks operating system. Standard software configurations were setup for PC/104 IOC application development to provide a familiar format for new projects as well as ease the conversion of applications from VME based IOCs to PC/104 IOCs. Many new projects at Jefferson Lab are going to employ PC/104 SBCs as IOCs and some applications have already been running them for accelerator operations. The PC/104 - RTEMS IOC provides a free open source Real-Time Operating System (RTOS), low cost/maintenance, easily installed/ configured, flexible, and reliable solution for accelerator control and 12GeV Upgrade projects.

  20. Conversion from 8800 to 8800PC - Evaluation and experience

    International Nuclear Information System (INIS)

    Though a final version of the software is pending the 8800PC operating system host computer is a welcomed change from the old Digital (DEC) host computer. The 8800PC host computer uses the Windows NT operating system and has proven to be very user friendly. Descriptive window messages replace the cryptic coding of the DEC host. Though numerous electrical components were replaced, system calibration remained constant. Calibrated Thermoluminescent (TL) output from a randomly selected 8815 field card was measured before and after the upgrade. The % difference, when comparing calibrated output from an upgraded reader to the non upgraded reader, ranged from 0.2 to 3%. The most disappointing aspect of the upgrade experience was the lag time between hardware installation and software completion

    Full Text Available Green computing is the study and practice of using computing resources efficiently. This give idea about reduce the use of hazardous materials maximize energy efficiency during the product's lifetime, and promote recyclability. Green computing can be broadly defined as the problem of reducing the overall carbon footprint of computing and communication infrastructure, such as data centers, by using energy-efficient design and operations. As the environmentalists and energy conservationists ponder over the issue of conserving environment, technologists have come out with a simple solution to let you contribute to the “Go Green” campaign- with the help of Green PCs. By using green computing practices; you can improve energy management, increase energy efficiency, reduce e-waste, and save money. Taking into consideration the popular use of information technology industry, it has to lead a revolution of sorts by turning green in a manner no industry has ever done before. It is worth emphasizing that this “green technology” should not be just about sound bytes to impress activists but concrete action and organizational policy. The plan towards Green PC should include new electronic products and services with optimum efficiency and all possible options towards energy savings and technical issues in high-performance green computing span the spectrum from green infrastructure like energy-efficient buildings, intelligent cooling systems, green power sources for green hardware multi-core computing systems, energy-efficient server design, energy-efficient solid-state storage for green software and applications.

    A high performance Beowulf (PC cluster) machine installed with Linux operating system and MPI (Message Passing Interface) for interprocessor communications has been constructed using Gigabit Ethernet and the communication software GAMMA (Genoa Active Message Machine), instead of the standard TCP/IP protocol. Fast C/Fortran compilers have been exploited with the GAMMA communication libraries. This method has eliminated large communication overhead of TCP/IP and resulted in significant increase in the computational performance of real application programs including the first-principle molecular dynamics simulation code.

    Full Text Available We have studied the hydrogen bonds in PC61BM solids. Inter-molecular interaction is analyzed theoretically for the well-defined monoclinic (P21/n structure. The results indicate that PC61BM combines into C–H⋯Od bonded molecular chains, where Od denotes the doubly-bonded O atom of PC61BM. The molecular chains are linked together by C–H⋯Os bonds, where Os denotes the singly-bonded O atom of PC61BM. To reveal the consequences of hydrogen bond formation on the structural properties of PC61BM solids (not limited to the monoclinic structure, we design and perform some experiments for annealed samples with the monoclinic (P21/n PC61BM as starting material. The experiments include differential scanning calorimetry, X-ray diffraction and infrared absorption measurements. Structural phase transitions are observed below the melting point. The C–H⋯Od bonds seem persisting in the altered structures. The inter-molecular hydrogen bonds can help to understand the phase separation in polymer/PC61BM blends and may be responsible for the existence of liquid PC61BM.

  6. Monte Carlo simulations on a 9-node PC cluster

    International Nuclear Information System (INIS)

    Monte Carlo simulation methods are frequently used in the fields of medical physics, dosimetry and metrology of ionising radiation. Nevertheless, the main drawback of this technique is to be computationally slow, because the statistical uncertainty of the result improves only as the square root of the computational time. We present a method, which allows to reduce by a factor 10 to 20 the used effective running time. In practice, the aim was to reduce the calculation time in the LNHB metrological applications from several weeks to a few days. This approach includes the use of a PC-cluster, under Linux operating system and PVM parallel library (version 3.4). The Monte Carlo codes EGS4, MCNP and PENELOPE have been implemented on this platform and for the two last ones adapted for running under the PVM environment. The maximum observed speedup is ranging from a factor 13 to 18 according to the codes and the problems to be simulated. (orig.)

    Recently, new site-specific seismic design response spectra were developed for Savannah River Site (SRS) performance category (PC) 1,2,3 and 4 structures, systems and components (SSCs) (WSRC, 1997, 1998) in accordance with DOE Standards. The lower performance categories (PC1 and PC2) site-specific design basis were not compatible with the response spectrum generated if building code guidelines were used (National Earthquake Hazard Reduction Program Recommended Provisions for Seismic Regulations for New Building, (NEHRP), 1997). These differences in criteria and approach should be documented and understood. Thus, Westinghouse Savannah River Company (WSRC) initiated this study to evaluate the difference between the building code hazard assessment (NEHRP) and the site-specific hazard evaluations used for SRS design.

  11. A PC-based telemetry system for acquiring and reducing data from multiple PCM streams

    Science.gov (United States)

    Simms, D. A.; Butterfield, C. P.

    1991-07-01

    The Solar Energy Research Institute's (SERI) Wind Research Program is using Pulse Code Modulation (PCM) Telemetry Data-Acquisition Systems to study horizontal-axis wind turbines. Many PCM systems are combined for use in test installations that require accurate measurements from a variety of different locations. SERI has found them ideal for data-acquisition from multiple wind turbines and meteorological towers in wind parks. A major problem has been in providing the capability to quickly combine and examine incoming data from multiple PCM sources in the field. To solve this problem, SERI has developed a low-cost PC-based PCM Telemetry Data-Reduction System (PC-PCM System) to facilitate quick, in-the-field multiple-channel data analysis. The PC-PCM System consists of two basic components. First, PC-compatible hardware boards are used to decode and combine multiple PCM data streams. Up to four hardware boards can be installed in a single PC, which provides the capability to combine data from four PCM streams directly to PC disk or memory. Each stream can have up to 62 data channels. Second, a software package written for use under DOS was developed to simplify data-acquisition control and management. The software, called the Quick-Look Data Management Program, provides a quick, easy-to-use interface between the PC and multiple PCM data streams. The Quick-Look Data Management Program is a comprehensive menu-driven package used to organize, acquire, process, and display information from incoming PCM data streams. The paper describes both hardware and software aspects of the SERI PC-PCM system, concentrating on features that make it useful in an experiment test environment to quickly examine and verify incoming data from multiple PCM streams. Also discussed are problems and techniques associated with PC-based telemetry data-acquisition, processing, and real-time display.

    Science.gov (United States)

    Cazaubon, Sylvie; Viegas, Pedro; Couraud, Pierre-Olivier

    2007-01-01

    It is now well established that both normal and pathological (or scrapie) isoforms of prion protein, PrPc and PrPsc respectively, are involved in the development and progression of various forms of neurodegenerative diseases, including scrapie in sheep, bovine spongiform encephalopathy (or "mad cow disease") and Creutzfeldt-Jakob disease in human, collectively known as prion diseases. The protein PrPc is highly expressed in the central nervous system in neurons and glial cells, and also present in non-brain cells, such as immune cells or epithelial and endothelial cells. Identification of the physiological functions of PrPc in these different cell types thus appears crucial for understanding the progression of prion diseases. Recent studies highlighted several major roles for PrPc that may be considered in two major domains : (1) cell survival (protection against oxidative stress and apoptosis) and (2) cell adhesion. In association with cell adhesion, distinct functions of PrPc were observed, depending on cell types : neuronal differentiation, epithelial and endothelial barrier integrity, transendothelial migration of monocytes, T cell activation. These observations suggest that PrPc functions may be particularly relevant to cellular stress, as well as inflammatory or infectious situations. PMID:17875293

    4D phase contrast MR imaging (4D PC MRI) has been introduced for spatiotemporal evaluation of intracranial hemodynamics in various cerebrovascular diseases. However, it still lacks validation with standards of reference. Our goal was to compare blood flow quantification derived from 4D PC MRI with transcranial ultrasound and 2D PC MRI. Velocity measurements within large intracranial arteries [internal carotid artery (ICA), basilar artery (BA), and middle cerebral artery (MCA)] were obtained in 20 young healthy volunteers with 4D and 2D PC MRI, transcranial Doppler sonography (TCD), and transcranial color-coded duplex sonography (TCCD). Maximum velocities at peak systole (PSV) and end diastole (EDV) were compared using regression analysis and Bland-Altman plots. Correlation of 4D PC MRI measured velocities was higher in comparison with TCD (r = 0.49-0.66) than with TCCD (0.35-0.44) and 2D PC MRI (0.52-0.60). In mid-BA and ICA C7 segment, a significant correlation was found with TCD (0.68-0.81 and 0.65-0.71, respectively). No significant correlation was found in carotid siphon. On average over all volunteers, PSVs and EDVs in MCA were minimally underestimated compared with TCD/TCCD. Minimal overestimation of velocities was found compared to TCD in mid-BA and ICA C7 segment. 4D PC MRI appears as valid alternative for intracranial velocity measurement consistent with previous reference standards, foremost with TCD. Spatiotemporal averaging effects might contribute to vessel size-dependent mild underestimation of velocities in smaller (MCA), and overestimation in larger-sized (BA and ICA) arteries, respectively. Complete spatiotemporal flow analysis may be advantageous in anatomically complex regions (e.g. carotid siphon) relative to restrictions of ultrasound techniques. (orig.)

    International Nuclear Information System (INIS)

    Asyn Driver was applied for PC/104 IOC serial communication systems at Jefferson Lab. We chose the ines GPIB-PC/104-XL as the GPIB interface module and developed a low lever device driver that is compatible with the Asyn Driver. Instrument device support was created to provide access to the operating parameters of GPIB devices. A Low level device driver for the serial communication board Model 104-COM-8SM was also developed to run under Asyn Driver. This serial interface board contains eight independent ports and provides effective RS-485, RS-422 and RS-232 multipoint communication. StreamDevice protocols were applied for the serial communications. The Asyn Driver in PC/104 IOC applications provides a standard interface between the high level device support and hardware level device drivers. This makes it easy to develop the GPIB and serial communication applications for PC/104 IOCs. A number of applications have been written to use the PC/104 Asyn driver in our control system at Jefferson Lab. (authors)

    International Nuclear Information System (INIS)

    Multiparameter data acquisition (MPA) systems which analyse nuclear events with respect to more than one property of the event are essential tools for the study of some complex nuclear phenomena requiring analysis of time coincident spectra. For better throughput and accuracy each parameter is digitized by its own ADC. A stand alone low cost IBM PC based 8-parameter data acquisition system developed by the authors makes use of Address Recording technique for acquiring data from eight 12 bit ADC's in the PC Memory. Two memory buffers in the PC memory are used in ping-pong fashion so that data acquisition in one bank and dumping of data onto PC disk from the other bank can proceed simultaneously. Data is acquired in the PC memory through DMA mode for realising high throughput and hardware interrupt is used for switching banks for data acquisition. A comprehensive software package developed in Turbo-Pascal offers a set of menu-driven interactive commands to the user for setting-up system parameters and control of the system. The system is to be used with pelletron accelerator. (author). 5 figs

    How is sensory information represented in the brain? A long-standing debate in neural coding is whether and how timing of spikes conveys information to downstream neurons. Although we know that neurons in the olfactory bulb (OB) exhibit rich temporal dynamics, the functional relevance of temporal coding remains hotly debated. Recent recording experiments in awake behaving animals have elucidated highly organized temporal structures of activity in the OB. In addition, the analysis of neural circuits in the piriform cortex (PC) demonstrated the importance of not only OB afferent inputs but also intrinsic PC neural circuits in shaping odor responses. Furthermore, new experiments involving stimulation of the OB with specific temporal patterns allowed for testing the relevance of temporal codes. Together, these studies suggest that the relative timing of neuronal activity in the OB conveys odor information and that neural circuits in the PC possess various mechanisms to decode temporal patterns of OB input.

  1. Population dose assessment: characteristics of PC CREAM

    International Nuclear Information System (INIS)

    This paper presents the main features of the PC CREAM, a program for performing radiological impact assessments due to radioactive discharges into the environment during the operation of radioactive and nuclear facilities. PC CREAM is a suite of six programs that can be used to estimate individual and collective radiation doses. The methodology of PC CREAM is based on updated environmental and dosimetric models, including ICRP 60 recommendations. The models include several exposure pathways and the input files are easy to access. The ergonomics of the program improves the user interaction and makes easier the input of local data. This program is useful for performing sensitivity analysis, siting studies and validation of model comparing the activity concentration output data with environmental monitoring data. The methodology of each module is described as well as the output data. (author)

  5. Installation and implementation of PC COSYMA

    International Nuclear Information System (INIS)

    COSYMA is a probabilistic reactor accident consequence assessment model developed in the 1980's by the research institutes of the EC countries, primarily by NRPB and KfK. In 1993 a simplified version of the program was released to be implemented on a PC. In the study the PC COSYMA program was applied to calculate as the end points nuclide concentrations, doses received, numbers of health effects, areas affected by countermeasures and other results related to countermeasure strategies. Some results are compared with the results obtained by the ARANO program developed by VTT Energy (Technical Research Centre of Finland) to quarantee proper interpretation of the application.

    2002-01-01

    A multidisciplinary, collaborative simulation has been performed on a Grid of geographically distributed PC clusters. The multiscale simulation approach seamlessly combines i) atomistic simulation backed on the molecular dynamics (MD) method and ii) quantum mechanical (QM) calculation based on the density functional theory (DFT), so that accurate but less scalable computations are performed only where they are needed. The multiscale MD/QM simulation code has been Grid-enabled using i) a modular, additive hybridization scheme, ii) multiple QM clustering, and iii) computation/communication overlapping. The Gridified MD/QM simulation code has been used to study environmental effects of water molecules on fracture in silicon. A preliminary run of the code has achieved a parallel efficiency of 94% on 25 PCs distributed over 3 PC clusters in the US and Japan, and a larger test involving 154 processors on 5 distributed PC clusters is in progress.

    Err. Wait. Please no! USB sticks are not innocent little things. They can quickly mutate into malicious nasty beasts! Just in the recent past, at least two physics experiments were suffering as their control and data acquisition PCs, respectively, were infected by USB sticks holding malicious code. A bit longer ago, a series of laptops were infected at a 2008 computing conference as an infected USB stick made its tour around. Bad luck for those who ran a Windows operating system and inserted that stick…   So, you found a USB stick in the cafeteria? Take care. If this were a lollipop, you wouldn’t just pick it up and lick it, would you? So beware of USB sticks whose origin or previous usage you don’t know. They might infect your PC once plugged in. In order to be on the safe side, accept and share only USB sticks whose owner you trust. Run up-to-date anti-virus software on your PC, make sure that its operating system is patched...

  13. Experience using EPICS on PC platforms

    International Nuclear Information System (INIS)

    The Experimental Physics and Industrial Control System (EPICS) has been widely adopted in the accelerator community. Although EPICS is available on many platforms, the majority of implementations have used UNIX workstations as clients, and VME- or VXI-based processors for distributed input output controllers. Recently, a significant portion of EPICS has been ported to personal computer (PC) hardware platforms running Microsoft's operating systems, and also Wind River System's real time vxWorks operating system. This development should significantly reduce the cost of deploying EPICS systems, and the prospect of using EPICS together with the many high quality commercial components available for PC platforms is also encouraging. A hybrid system using both PC and traditional platforms is currently being implemented at LANL for LEDA, the low energy demonstration accelerator under construction as part of the Accelerator Production of Tritium (APT) project. To illustrate these developments the authors compare their recent experience deploying a PC-based EPICS system with experience deploying similar systems based on traditional (UNIX-hosted) EPICS hardware and software platforms

  17. COMPPAP - COMPOSITE PLATE BUCKLING ANALYSIS PROGRAM (IBM PC VERSION)

    Science.gov (United States)

    Smith, J. P.

    1994-01-01

    The Composite Plate Buckling Analysis Program (COMPPAP) was written to help engineers determine buckling loads of orthotropic (or isotropic) irregularly shaped plates without requiring hand calculations from design curves or extensive finite element modeling. COMPPAP is a one element finite element program that utilizes high-order displacement functions. The high order of the displacement functions enables the user to produce results more accurate than traditional h-finite elements. This program uses these high-order displacement functions to perform a plane stress analysis of a general plate followed by a buckling calculation based on the stresses found in the plane stress solution. The current version assumes a flat plate (constant thickness) subject to a constant edge load (normal or shear) on one or more edges. COMPPAP uses the power method to find the eigenvalues of the buckling problem. The power method provides an efficient solution when only one eigenvalue is desired. Once the eigenvalue is found, the eigenvector, which corresponds to the plate buckling mode shape, results as a by-product. A positive feature of the power method is that the dominant eigenvalue is the first found, which is this case is the plate buckling load. The reported eigenvalue expresses a load factor to induce plate buckling. COMPPAP is written in ANSI FORTRAN 77. Two machine versions are available from COSMIC: a PC version (MSC-22428), which is for IBM PC 386 series and higher computers and compatibles running MS-DOS; and a UNIX version (MSC-22286). The distribution medium for both machine versions includes source code for both single and double precision versions of COMPPAP. The PC version includes source code which has been optimized for implementation within DOS memory constraints as well as sample executables for both the single and double precision versions of COMPPAP. The double precision versions of COMPPAP have been successfully implemented on an IBM PC 386 compatible running

    1990-05-01

    Recent advances in algorithms and techniques for speech coding now permit high quality voice reproduction at remarkably low bit rates. The advent of powerful single-ship signal processors has made it cost effective to implement these new and sophisticated speech coding algorithms for many important applications in voice communication and storage. Some of the main ideas underlying the algorithms of major interest today are reviewed. The concept of removing redundancy by linear prediction is reviewed, first in the context of predictive quantization or DPCM. Then linear predictive coding, adaptive predictive coding, and vector quantization are discussed. The concepts of excitation coding via analysis-by-synthesis, vector sum excitation codebooks, and adaptive postfiltering are explained. The main idea of vector excitation coding (VXC) or code excited linear prediction (CELP) are presented. Finally low-delay VXC coding and phonetic segmentation for VXC are described.

  19. CLIPS - C LANGUAGE INTEGRATED PRODUCTION SYSTEM (IBM PC VERSION)

    Science.gov (United States)

    Riley, G.

    1994-01-01

    The C Language Integrated Production System, CLIPS, is a shell for developing expert systems. It is designed to allow artificial intelligence research, development, and delivery on conventional computers. The primary design goals for CLIPS are portability, efficiency, and functionality. For these reasons, the program is written in C. CLIPS meets or outperforms most micro- and minicomputer based artificial intelligence tools. CLIPS is a forward chaining rule-based language. The program contains an inference engine and a language syntax that provide a framework for the construction of an expert system. It also includes tools for debugging an application. CLIPS is based on the Rete algorithm, which enables very efficient pattern matching. The collection of conditions and actions to be taken if the conditions are met is constructed into a rule network. As facts are asserted either prior to or during a session, CLIPS pattern-matches the number of fields. Wildcards and variables are supported for both single and multiple fields. CLIPS syntax allows the inclusion of externally defined functions (outside functions which are written in a language other than CLIPS). CLIPS itself can be embedded in a program such that the expert system is available as a simple subroutine call. Advanced features found in CLIPS version 4.3 include an integrated microEMACS editor, the ability to generate C source code from a CLIPS rule base to produce a dedicated executable, binary load and save capabilities for CLIPS rule bases, and the utility program CRSV (Cross-Reference, Style, and Verification) designed to facilitate the development and maintenance of large rule bases. Five machine versions are available. Each machine version includes the source and the executable for that machine. The UNIX version includes the source and binaries for IBM RS/6000, Sun3 series, and Sun4 series computers. The UNIX, DEC VAX, and DEC RISC Workstation versions are line oriented.

  20. Development of GIFT-PC: the software with multi-drawing functions of three dimensional geometries

    International Nuclear Information System (INIS)

    The Combinatorial Geometry (CG) is a general-purpose geometry package used on radiation transport simulation codes. It is quite useful to illustrate the CG geometries on a simulation code because the visible information of the CG geometries used in a calculation can avoid some mistakes in the case of complicated data, and make it easier to understand the calculation models in the case of presentations. GIFT code (Geographic Information For Target) hsa been developed at Ballistic Research Laboratory, US, for the purpose of illustrating the components of a target from any point of view, calculating a projected area or volume and checking the correctness of the geometry description. Using the drawing functions of GIFT code, perspective or isometric views of a target can be obtained from various points of view. The present report describes the overview of GIFT code and the development of GIFT-PC. GIFT-PC, based on GIFT code, has been developed for easier drawings of three-dimensional geometries using the GUI (Graphical User Interface) system of personal computers, and can be used in various fields as a useful drawing tool for CG geometries.

    Full Text Available Pc3 geomagnetic field fluctuations detected at low latitude (L'Aquila, Italy during the passage of a high velocity solar wind stream, characterized by variable interplanetary magnetic field conditions, are analyzed. Higher frequency resonant fluctuations and lower frequency phenomena are simultaneously observed; the intermittent appearance and the variable frequency of the longer period modes can be well interpreted in terms of the variable IMF elements; moreover their polarization characteristics are consistent with an origin related to external waves propagating in antisunward direction. A comparison with simultaneous observations performed at Terra Nova Bay (Antarctica provides additional evidence for a clear relationship between the IMF and Pc3 pulsations also at very high latitudes.

  4. PC imaging system for reactor NDE

    International Nuclear Information System (INIS)

    PC-based systems have been given recent attention by EPRI to organize and manage inspection data (RP-2405-15, TestPro system); integrate with larger, mainframe computers to maintain dialogue for on-site and remote applications; and, in this project, to aid the operator in providing guidance to render decisions on the data. The PC system configuration for this project consisted of a central processing unit (CPU), a hard disk and a floppy disk, 640K bytes of system memory, a high-resolution graphics card and compatible color monitor, and a mouse for operator interaction with software. The software package was written in FORTRAN under the PC Disk Operating System (PC-DOS) and utilized a graphics package for image display. Application of this package to crack-counterbore discrimination in piping welds was investigated. Present automatic techniques utilize signal features from single, A-scan data to render a decision on whether the reflector is benign (i.e., counterbore, weld root) or a crack. However, experienced manual operators in the field make reliable decisions based on the integrated response from the reflector as the transducer is scanned past the suspicious region. Since this software package could display and manipulate ensemble A-scans, spatial features - similar to those used by experts - were developed as discriminants. Ultrasonic responses from intergranular stress corrosion cracks (IGSCCs) were discovered to vary both in time-of-flight and in their amplitude, whereas counterbore responses were more consistent. The software package contains methods for viewing and quantifying these spatial features

  5. COSYMA, a mainframe and PC program package for assessing the consequences of hypothetical accidents

    International Nuclear Information System (INIS)

    COSYMA (Code System from MARIA) is a program package for assessing the off-site consequences of accidental releases of radioactive material to atmosphere, developed as part of the European Commission's MARIA programme (Methods for Assessing the Radiological Impact of Accidents). COSYMA represents a fusion of ideas and modules from the Forschungszetrum Karlsruhe program system UFOMOD, the National Radiological Protection Board program MARC and new model developments together with data libraries from other MARIA contractors. Mainframe and PC versions of COSYMA are distributed to interested users by arrangement with the European Commission. The system was first released in 1990, and has subsequently been updated. The program system uses independent modules for the different parts of the analysis, and so permits a flexible problem-oriented application to different sites, source terms, emergency plans and the needs of users in the various parts of Europe. Users of the mainframe system can choose the most appropriate combination of modules for their particular application. The PC version includes a user interface which selects the required modules for the endpoints specified by the user. This paper describes the structure of the mainframe and PC versions of COSYMA, and summarises the models included in them. The mainframe or PC versions of COSYMA have been distributed to more than 100 organisations both inside and outside the European Union, and have been used in a wide variety of applications. These range from full PRA level 3 analyses of nuclear power and research reactors to investigations on advanced containment concepts and the preplanning of off-site emergency actions. Some of the experiences from these applications are described in the paper. An international COSYMA user group has been established to stimulate communication between the owners, developers and users of the code and to serve as a reference point for questions relating to the code. The group produces

  6. Simulation with PC-based-p-cat package

    International Nuclear Information System (INIS)

    The PWR Core And Thermohydraulics (P-CAT) package is the first engineering grade real-time simulation code developed to take advantage of today's PC power. The package consists of three important products: CAST (Control And Simulation Tool) system, MACK (Micro-node Analysis of Core Kinetics) model and TPFN (Two Phase Flow Network) thermal hydraulics model. The CAST system offers database management, module scanning, interactive debugging, real-time executives, super graphics, etc. This paper reports that the 3-D MACK model is a FLARE type model, with the major difference of dropping the adiabatic approach. This micro-node model, with 193 (one for each fuel assembly) radial nodes and 6 axial nodes (a total of 158 nodes) for a typical Westinghouse PWR core, was recently completed and benchmarked. The major achievements of the code are its accuracy and time-efficiency. The MACK model is much more accurate than the coarse node (typically 100-200 nodes) models, especially during asymmetrical rod movements. The TPFN model is an engineering thermal hydraulics model. Drift flux formulations are used to faithfully simulate the single phase and two phase phenomena. Presence of noncondensibles can also be simulated. The model uses a unique numerical method that computes the nodal flow rates and the system pressure at the same time. TPFN model has been applied to the simulation of the RCS and steam generators of a Westinghouse plant and integrated with the MACK core model

    A novel subtilisin-like protein, PC8, was identified by PCR using degenerate primers to conserved amino acid residues in the catalytic region of members of the prohormone convertase family. PC8 was predicted to be 785 residues long and was structurally related to the mammalian convertases furin, PACE4, PC1 and PC2, sharing more than 50% amino acid identity over the catalytic region with these family members. PC8 possessed the catalytically important Asp, His, Asn and Ser amino acids, the homo B domain of this family of enzymes and a C-terminal hydrophobic sequence indicative of a transmembrane domain. Structurally, PC8 is more related to furin and PACE4 than to PC1 or PC2. Like furin and PACE4, PC8 mRNA was found to be widely expressed; this is in contrast with PC1 and PC2, which have a restricted distribution. Two transcripts, of 4.5 and 3.5 kb, were detected in both human cell lines and rat tissues. Unlike furin and PACE4, both of which map to chromosome 15, PC8 maps to chromosome 11q23-11q24, suggesting that this gene may have resulted from an ancient gene duplication event from either furin or PACE4, or conversely that these genes arose from PC8.

  9. CFARMHD -- A MathCAD PC program to evaluate performance and economics of CFARII fusion reactors

    International Nuclear Information System (INIS)

    This report describes a PC computer program ''CFARMHD'', developed to evaluate the performance (MHD cycle efficiency) and economics (Cost-of-Electricity CoE) for pulsed fusion reactors using the Compact Fusion Advanced Rankine II (CFARII) MHD Balance of Plant (BoP). The CFARII concept to which this code applies is generic to any fusion driver which can be characterized by an assumed yield Y (GJ), target gain G, and unit cost ($/joule driver). The CFARMHD code models the sizes, masses, energies, mass flows and powers corresponding to the physical systems and optimizes them to minimize CoE for given Y, G, $/joule, and choice of material for the working fluid (cast as solid spherical shells around the target). A description of the models used in the CFARMHD code is given in Section 11, and the CoE minimization procedure used in the code is described in Section III

  11. Phosphatidylcholine (PC) biosynthesis in pancreatic islets of Langerhans

    International Nuclear Information System (INIS)

    Islets of Langerhans isolated from rat pancreata were incubated with [14C]choline to determine the biosynthesis of PC by the CDP choline to determine the biosynthesis of PC by the CDPcholine pathway. Recovery of [14C]PC in islet membranes was time-related, and stimulated by glucose (17mM) during 60 min. The rate of PC synthesis was constant during 60 min with glucose stimulation. In contrast, the sulfonylurea tolbutamide (2 mM) reduced the recovery of [14C]choline in PC, and 8-bromo-cyclic AMP (5 mM) did not significantly affect [14C]PC recovery. Incubation of islets in Ca2+-free medium enhanced glucose-stimulated recovery of [14C]choline-labeled PC due to the inhibition of phospholipase and phospholipid hydrolysis. Inhibition of CTP:phosphocholine cytidylyltransferase with 5-deoxy-5'-isobutylthioadenosine (SIBA) reduced [14C]PC levels and insulin release in a concentration dependent manner. Treatment with SIBA also reduced Mg2+-dependent Ca2+-ATPase activity in islet microsomes. Quantitation of membrane PC showed that glucose stimulation did not alter islet P levels. Thus, islet PC biosynthesis is linked to glucose stimulation and contributes to the maintenance of PC levels in membranes undergoing exocytosis and phospholipid hydrolysis. Adequate PC levels support Ca2+ pump activity and secretory mechanisms

  12. A TDC-PC interface for DPAC

    International Nuclear Information System (INIS)

    In a standard DPAC (time Differential Perturbed Angular Correlation) setup the time measuring is mostly done by a TAC (time-to-amplitude converter) connected through an ADC to a computer or MCA. Accelerator on-line techniques more often use a TDC (time-to-digital converter) which eliminates nonlinearities and noise in the analog part of the TAC-ADC combination. The authors briefly describe an interface for the LeCroy 4201 TDC to an IBM-PC. The system is dedicated to the DPAC technique, but can easily be modified for other applications, e.g. μSR and DPAD. 2 figs

    A car license plate reader (CLPR) using fuzzy inference and neural network algorithm has been developed in Industrial Technology Research Institute (ITRI) and installed in highway toll stations to identify stolen cars. It takes an average of 0.7 seconds to recognize a car license plate by using a PC with 80486-50 CPU. The recognition rate of the system is about 97%. The techniques of CLPR include vehicle sensing, image grab control, optic pre- processing, lighting, and optic character recognition (OCR). The CLPR can be used in vehicle flow statistics, the checking of stolen vehicles, automatic charging systems in parking lots or garage management, and so on.

  1. Comparative biosynthesis, covalent post-translational modifications and efficiency of prosegment cleavage of the prohormone convertases PC1 and PC2: glycosylation, sulphation and identification of the intracellular site of prosegment cleavage of PC1 and PC2.

    1993-09-15

    We present herein the pulse-chase analysis of the biosynthesis of the prohormone convertases PC1 and PC2 in the endocrine GH4C1 cells infected with vaccinia virus recombinants expressing these convertases. Characterization of the pulse-labelled enzymes demonstrated that pro-PC1 (88 kDa) is cleaved into PC1 (83 kDa) and pro-PC2 (75 kDa) into PC2 (68 kDa). Secretion of glycosylated and sulphated PC1 (84 kDa) occurs about 30 min after the onset of biosynthesis, whereas glycosylated and sulphated PC2 (68 kDa) is detected in the medium after between 1 and 2 h. Furthermore, in the case of pro-PC2 only, we observed that a fraction of this precursor escapes glycosylation. A small proportion (about 5%) of the intracellular glycosylated pro-PC2 (75 kDa) is sulphated, and it is this glycosylated and sulphated precursor that is cleaved into the secretable 68 kDa form of PC2. Major differences in the carbohydrate structures of PC1 and PC2 are demonstrated by the resistance of the secreted PC1 to endoglycosidase H digestion and sensitivity of the secreted PC2 to this enzyme. Inhibition of N-glycosylation with tunicamycin caused a dramatic intracellular degradation of these convertases within the endoplasmic reticulum, with the net effect of a reduction in the available activity of PC1 and PC2. These results emphasize the importance of N-glycosylation in the folding and stability of PC1 and PC2. Pulse-labelling experiments in uninfected mouse beta TC3 and rat Rin m5F insulinoma cells, which endogenously synthesize PC2, showed that, as in infected GH4C1 cells, pro-PC2 predominates intracellularly. In order to define the site of prosegment cleavage, pulse-chase analysis was performed at low temperature (15 degrees C) or after treatment of GH4C1 cells with either brefeldin A or carbonyl cyanide m-chlorophenylhydrazone. These results demonstrated that the onset of the conversions of pro-PC1 into PC1 and non-glycosylated pro-PC2 into PC2 (65 kDa) occur in a pre-Golgi compartment

  2. The 1996 ENDF pre-processing codes

    International Nuclear Information System (INIS)

    The codes are named 'the Pre-processing' codes, because they are designed to pre-process ENDF/B data, for later, further processing for use in applications. This is a modular set of computer codes, each of which reads and writes evaluated nuclear data in the ENDF/B format. Each code performs one or more independent operations on the data, as described below. These codes are designed to be computer independent, and are presently operational on every type of computer from large mainframe computer to small personal computers, such as IBM-PC and Power MAC. The codes are available from the IAEA Nuclear Data Section, free of charge upon request. (author)

    2011-01-01

    Near-Earth Asteroids can be hazardous to the Earth, due to their orbital characteristics and proximity to inner Solar System planets. Using three sets of CCD images collected in June and July 2011, the orbital elements of asteroid 1994 PC1 were determined at solar opposition. The body's specific right ascension and declination were calculated through least squares plate reduction (taking parallax into account) and compared to those of the Jet Propulsion Laboratory. These data were then used to find 1994 PC1's orbital elements, as well as any statistical uncertainty. This research points to an eccentricity of 0.3272 (+0.00009 or -0.0005), a semi major axis of 1.3401 AU (+0.0001 AU or -0.0004 AU), an inclination angle of 33.30^{\\circ} (+0.05^{\\circ} or -0.01^{\\circ}), a longitude of the ascending node of 118.01^{\\circ} (+0.09^{\\circ} or -0.02^{\\circ}), an argument of perihelion of 47.14^{\\circ} (+0.005^{\\circ} or -0.08^{\\circ}), and a time of last perihelion of JD 2455642.88 (+0.007 or -0.03).

  4. MARS Code in Linux Environment

    International Nuclear Information System (INIS)

    The two-phase system analysis code MARS has been incorporated into Linux system. The MARS code was originally developed based on the RELAP5/MOD3.2 and COBRA-TF. The 1-D module which evolved from RELAP5 alone could be applied for the whole NSSS system analysis. The 3-D module developed based on the COBRA-TF, however, could be applied for the analysis of the reactor core region where 3-D phenomena would be better treated. The MARS code also has several other code units that could be incorporated for more detailed analysis. The separate code units include containment analysis modules and 3-D kinetics module. These code modules could be optionally invoked to be coupled with the main MARS code. The containment code modules (CONTAIN and CONTEMPT), for example, could be utilized for the analysis of the plant containment phenomena in a coupled manner with the nuclear reactor system. The mass and energy interaction during the hypothetical coolant leakage accident could, thereby, be analyzed in a more realistic manner. In a similar way, 3-D kinetics could be incorporated for simulating the three dimensional reactor kinetic behavior, instead of using the built-in point kinetics model. The MARS code system, developed initially for the MS Windows environment, however, would not be adequate enough for the PC cluster system where multiple CPUs are available. When parallelism is to be eventually incorporated into the MARS code, MS Windows environment is not considered as an optimum platform. Linux environment, on the other hand, is generally being adopted as a preferred platform for the multiple codes executions as well as for the parallel application. In this study, MARS code has been modified for the adaptation of Linux platform. For the initial code modification, the Windows system specific features have been removed from the code. Since the coupling code module CONTAIN is originally in a form of dynamic load library (DLL) in the Windows system, a similar adaptation method

    1992-01-01

    The recent advancement of computer technology makes reservoir simulations feasible in a personal computer (PC) environment. This manual provides a guide for running BOAST-VHS, a black oil reservoir simulator for vertical/horizontal/slant wells, using a PC. In addition to detailed explanations of input data file preparation for simulation runs, special features of BOAST-VHS are described and three sample problems are presented. BOAST-VHS is a cost-effective and easy-to-use reservoir simulation tool for the study of oil production from primary depletion and waterflooding in a black oil reservoir. The well model in BOAST-VHS permits specification of any combination of horizontal, slanted, and vertical wells in the reservoir. BOAST-VHS was designed for an IBM PC/AT, PS-2, or compatible computer with 640 K bytes of memory. BOAST-VHS can be used to model a three-dimensional reservoir of up to 810 grid blocks with any combination of rows, columns, and layers, depending on the input data supplied. This dynamic redimensioning feature facilitates simulation work by avoiding the need to recompiling the simulator for different reservoir models. Therefore the program is only supplied as executable code without any source code.

    Science.gov (United States)

    Kantak, A. V.

    1994-01-01

    The AKPLOT routine was designed for engineers and scientists who use graphs as an integral part of their documentation. AKPLOT allows the user to generate a graph and edit its appearance on a CRT. This graph may undergo many interactive alterations before it is finally screen dumped to a printer for a hard copy plot. The finished AKPLOT graph may be stored in a file for future use. Features available in AKPLOT include: multiple curves on a single plot; combinations of linear and logarithmic scale axes; Lagrange interpolation of selected curves; shrink, expand, zoom, and tilt; ten different symbols and four different colors for curves; and three different grid types. AKPLOT enables the user to perform least squares fitting of all or selected curves with polynomials of up to 99 degrees and examine the least squares coefficients. The user must provide the data points to be plotted by one of two methods: 1) supplying an external file of X-Y values for all curves, or 2) computing the X-Y vectors by either placing BASIC code describing the relation in a designated section of the AKPLOT code or dynamically entering a one line function. Using either technique, the X-Y values are input to the computer only once, as the iterative graph edit loop bypasses the data input step for faster execution. AKPLOT is written in BASIC for interactive execution and has been implemented on an IBM PC series computer operating under DOS. AKPLOT requires a graphics board and a color monitor. This program was originally developed in 1986 and later revised in 1987.

  7. GPIB interface of IBM-PC compatible microcomputer and multimeter HP3457A for the automatization of temperature measurements

    International Nuclear Information System (INIS)

    The measurement of temperature distribution of the beam transport devices, utilized in the IEAv linac, takes several hours to be completed. At the beam transport laboratory, these experiments are controlled with the help of a MS-quick BASIC code denominated TERMOJ. This code uses the software of STD-8410 plate to promote the communication between an IBM-PC compatible microcomputer and the programmable multimeter HP3457A via GPIB interface. This work presents information for the automation of experiments using thermocouples to obtain temperature distributions with the TERMOJ code. Also, suggestions of how modify the algorithm of the program for the specific situations are indicated. (author)

  8. COBRA-IV PC: A personal computer version of COBRA-IV-I for thermal-hydraulic analysis of rod bundle nuclear fuel elements and cores

    International Nuclear Information System (INIS)

    COBRA-IV PC is a modified version of COBRA-IV-I, adapted for use with most IBM PC and PC-compatible desktop computers. Like COBRA-IV-I, COBRA-IV PC uses the subchannel analysis approach to determine the enthalpy and flow distribution in rod bundles for both steady-state and transient conditions. The steady-state and transient solution schemes used in COBRA-IIIC are still available in COBRA-IV PC as the implicit solution scheme option. An explicit solution scheme is also available, allowing the calculation of severe transients involving flow reversals, recirculations, expulsions, and reentry flows, with a pressure or flow boundary condition specified. In addition, several modifications have been incorporated into COBRA-IV PC to allow the code to run on the PC. These include a reduction in the array dimensions, the removal of the dump and restart options, and the inclusion of several code modifications by Oregon State University, most notably, a critical heat flux correlation for boiling water reactor fuel and a new solution scheme for cross-flow distribution calculations. 7 refs., 8 figs., 1 tab

  10. PC based systems for measurements in reactor physics

    International Nuclear Information System (INIS)

    A set of applications was developed, utilizing the advantages of coupling acquisition cards to PCs, fructifying the experience in reactor physics measurements. The main objectives were: on-line work with advanced codes of gamma spectra analysis, performing on-line corrections for neutron detectors with complex dynamics and dynamic processing of signals from ratemeter and frequency-meter lines. The advanced date processing is carried out at foreground level while the data acquisition and primary processing are carried out at background level. The achieved software covers pulse-height analyzers, ratemeters, frequency meters, multichannel counting ratemeters and noise analysis. By making use of a simple hardware and by increasing the weight of software we improved the performance of generally used acquisition cards, fulfilling, at the same time, the requirements for reactor physics accurate measurements. In-reactor experiments or experiments using neutron sources were used for testing the PC based systems as well as for adjusting their parameters. Extensions to reactor control/safety systems are conceived as developing models systems, because they proved to be versatile tools for testing physics and safety principles. Thus, this work represents an interface between reactor physics and reactor instrumentation and control engineering

    The white dwarf luminosity function is an important tool to understand the properties of the Solar neighborhood, like its star formation history, and its age. Here we present a population synthesis study of the white dwarf population within 40~pc from the Sun, and compare the results of this study with the properties of the observed sample. We use a state-of-the-art population synthesis code based on Monte Carlo techniques, that incorporates the most recent and reliable white dwarf cooling sequences, an accurate description of the Galactic neighborhood, and a realistic treatment of all the known observational biases and selection procedures. We find a good agreement between our theoretical models and the observed data. In particular, our simulations reproduce a previously unexplained feature of the bright branch of the white dwarf luminosity function, which we argue is due to a recent episode of star formation. We also derive the age of the Solar neighborhood employing the position of the observed cut-off of ...

  12. Materials accounting system for an IBM PC

    International Nuclear Information System (INIS)

    We have adapted the Los Alamos MASS accounting system for use on an IBM PC/AT at the Fuels Manufacturing Facility (FMF) at Argonne National Laboratory-West (ANL-WEST) in Idaho Falls, Idaho. Cost of hardware and proprietary software was less than $10,000 per station. The system consists of three stations between which accounting information is transferred using floppy disks accompanying special nuclear material shipments. The programs were implemented in dBASEIII and were compiled using the proprietary software CLIPPER. Modifications to the inventory can be posted in just a few minutes, and operator/computer interaction is nearly instantaneous. After the records are built by the user, it takes 4 to 5 seconds to post the results to the database files. A version of this system was specially adapted and is currently in use at the FMF facility at Argonne National Laboratory in Idaho Falls. Initial satisfaction is adequate and software and hardware problems are minimal

    "Orandum est ut sit mens sana in corpore sano" ("You should pray for a healthy mind in a healthy body"). This phrase is a shortened citation from the satirical work of the Roman poet Juvenal. It highlights the significant role of physical as well as mental health. Aesthetic ideals have existed since the Archaic age, but they are not necessarily the same in different continents. Being familiar with aesthetic ideals in different cultures might help to accommodate patients' needs and wishes in today's globalised world. Therefore, fellowship programs such as the program organised by the Association of German Aesthetic Plastic Surgeons ("VDÄPC") are very important for young plastic surgeons who are interested in improving their surgical skills and experience. After all, aesthetic surgery is a dynamic specialty, which requires aesthetic plastic surgeons to undergo continued medical education. PMID:27096212

    M. K. Hudson

    2004-01-01

    Full Text Available A study of Pc-5 magnetic pulsations using data from the Combined Release and Radiation Effects Satellite (CRRES was carried out. Three-component dynamic magnetic field spectrograms have been used to survey ULF pulsation activity for the approximate fourteen month lifetime of CRRES. Two-hour panels of dynamic spectra were examined to find events which fall into two basic categories: 1 toroidal modes (fundamental and harmonic resonances and 2 poloidal modes, which include compressional oscillations. The occurence rates were determined as a function of L value and local time. The main result is a comparable probability of occurence of toroidal mode oscillations on the dawn and dusk sides of the magnetosphere inside geosynchronous orbit, while poloidal mode oscillations occur predominantly along the dusk side, consistent with high azimuthal mode number excitation by ring current ions.

    Pc-5 pulsations following Storm Sudden Commencements (SSCs were examined separately. The spatial distribution of modes for the SSC events was consistent with the statistical study for the lifetime of CRRES. The toroidal fundamental (and harmonic resonances are the dominant mode seen on the dawn-side of the magnetosphere following SSCs. Power is mixed in all three components. In the 21 dusk side SSC events there were only a few examples of purely compressional (two or radial (one power in the CRRES study, a few more examples of purely toroidal modes (six, with all three components predominant in about half (ten of the events.

  1. Speech coding

    Energy Technology Data Exchange (ETDEWEB)

    Ravishankar, C., Hughes Network Systems, Germantown, MD

    1998-05-08

    Speech is the predominant means of communication between human beings and since the invention of the telephone by Alexander Graham Bell in 1876, speech services have remained to be the core service in almost all telecommunication systems. Original analog methods of telephony had the disadvantage of speech signal getting corrupted by noise, cross-talk and distortion Long haul transmissions which use repeaters to compensate for the loss in signal strength on transmission links also increase the associated noise and distortion. On the other hand digital transmission is relatively immune to noise, cross-talk and distortion primarily because of the capability to faithfully regenerate digital signal at each repeater purely based on a binary decision. Hence end-to-end performance of the digital link essentially becomes independent of the length and operating frequency bands of the link Hence from a transmission point of view digital transmission has been the preferred approach due to its higher immunity to noise. The need to carry digital speech became extremely important from a service provision point of view as well. Modem requirements have introduced the need for robust, flexible and secure services that can carry a multitude of signal types (such as voice, data and video) without a fundamental change in infrastructure. Such a requirement could not have been easily met without the advent of digital transmission systems, thereby requiring speech to be coded digitally. The term Speech Coding is often referred to techniques that represent or code speech signals either directly as a waveform or as a set of parameters by analyzing the speech signal. In either case, the codes are transmitted to the distant end where speech is reconstructed or synthesized using the received set of codes. A more generic term that is applicable to these techniques that is often interchangeably used with speech coding is the term voice coding. This term is more generic in the sense that the

    International Nuclear Information System (INIS)

    A pc-interface module has been developed that provides an easy way to interface PC with I/O devices. This MSC51 micro controller based module accepts series of commands from a personal computer through a serial port. The commands are defined to easily control 24 I/O lines available on the module. These lines can be individually used as either input or output that make the module very verstile. A command is received by the module on ASCII string basis. Each character sent to the module will give an interrupt. The firmware's interrupt handler will store the character in a buffer until end of command character arrives. The firmware then parses and interpreters the command and responses accordingly

    Highlights: • We determine the optical properties of two fullerene derivatives using ellipsometry. • Multisample analysis is applied to verify the uniqueness of the model. • The energy position of the oscillators used are compared with ones present in the parent molecules. - Abstract: Spectroscopic ellipsometry is used to determine the optical properties and to extract electronic transitions of PC60BM and PC70BM thin films in the UV–Visible range. By means of a sum of Gaussian oscillators, the imaginary parts of dielectric functions of both materials are modeled. The physical meaning of each model is checked by comparing the energy position of the oscillators with known optical transitions of the C60 and C70 molecules as revealed in literature by others techniques. It is shown that spectroscopic ellipsometry is a powerful technique to investigate the electronic structure of pi-conjugated molecules

They are available from the IAEA Nuclear Data Section, free of charge upon request, on magnetic tape or a set of HD diskettes. (author)

  8. Computer code ONEBFP. Final report

    International Nuclear Information System (INIS)

    The final product of Task 10, the computer code ONEBFP, was delivered to the customer on 28 July 1995. ONEBFP is a newly written transport module specifically designed for use in the BOXIEMP code system. ONEBFP uses advanced transport methods and should provide better accuracy than the existing transport module in BOXIEMP. ONEBFP was designed for ease of maintenance and replaces an existing transport module consisting of over 100,000 lines of code. ONEBFP consists of 6632 lines of Fortran code, of which 3412 are comment lines used for documentation. Dynamic memory storage is used for all data arrays. Three methods are available; one is chosen at installation time. They are Fortran 90 automatic arrays, Fortran 90 Allocate/Deallocate, or the Allocate/Deallocate extension to Fortran 77 allowed in the Microsoft Fortran Powerstation product for IBM PC compatibles. ONEBFP requires two input files, a binary cross section input file and a text file of controls and other specifications. Two output files are produced, the first is a report file that regurgitates the input from the text input and a summary of how the calculation progressed and the second contains detailed pointwise and angular quantifies such as the flux that are the results of the calculation. This second file serves as the interface to the postprocessing modules of the BOXIEMP code

    OpenAIRE

    Klappenecker, Andreas; Roetteler, Martin

    2000-01-01

    Knill introduced a generalization of stabilizer codes, in this note called Clifford codes. It remained unclear whether or not Clifford codes can be superior to stabilizer codes. We show that Clifford codes are stabilizer codes provided that the abstract error group has an abelian index group. In particular, if the errors are modelled by tensor products of Pauli matrices, then the associated Clifford codes are necessarily stabilizer codes.

  13. MCNP code

    International Nuclear Information System (INIS)

    The MCNP code is the major Monte Carlo coupled neutron-photon transport research tool at the Los Alamos National Laboratory, and it represents the most extensive Monte Carlo development program in the United States which is available in the public domain. The present code is the direct descendent of the original Monte Carlo work of Fermi, von Neumaum, and Ulam at Los Alamos in the 1940s. Development has continued uninterrupted since that time, and the current version of MCNP (or its predecessors) has always included state-of-the-art methods in the Monte Carlo simulation of radiation transport, basic cross section data, geometry capability, variance reduction, and estimation procedures. The authors of the present code have oriented its development toward general user application. The documentation, though extensive, is presented in a clear and simple manner with many examples, illustrations, and sample problems. In addition to providing the desired results, the output listings give a a wealth of detailed information (some optional) concerning each state of the calculation. The code system is continually updated to take advantage of advances in computer hardware and software, including interactive modes of operation, diagnostic interrupts and restarts, and a variety of graphical and video aids

    Thermoluminescence (TL) Reader is an important basic equipment for any Luminescence researcher. It can be used to study and characterize TL of materials in different forms (Powder, Crystals and discs). By considering the requirement for a Low Cost integral TL Reader, Nucleonix Systems has taken up the task and developed a Low cost PC Controlled TL Reader by integrating complete electronics hardware circuits (comprising of Power Electronics, Low/High voltage supplies, Temperature controller, Microcontroller based data acquisition circuits having serial counter, ADC, DAC, EEPROM, PMT, PMT housing, sample heating system, drawer assembly etc.,) in to a single enclosure. This Integral TL Reader unit gets connected to the personal computer system through serial port (RS232C). The user interface to the system is through front-end VB software defined Graphics User Interface (GUI). The primary objective of this development has been not only to reduce the cost but also a simple reliable system and there by make it affordable to many of the University Researchers and other users in India and other Asian countries.

  16. 100 pc renewable energies: the last obstacles

    International Nuclear Information System (INIS)

    As some countries or territories have set a target of 100 pc of renewable energies by 2015, a first article discusses the different components of a scenario corresponding to this objective: reduction of primary energy consumption, sobriety, efficiency, electricity and heat production, mobility, development of exchanges and solidarities between territories, new roles for the different actors. A second article briefly presents the situation of different cities and territories in terms of production of renewable energies and of energy savings (Vancouver, Costa Rica, Canaries Islands, the region of Thouars in France, Denmark, Frankfurt, and Bangladesh). Two persons belonging either to a company or to a public body, both committed in energy efficiency issues, give their opinion on issues of governance and innovation. The next article outlines that, despite the content of the law on energy transition, there is still much to be done to develop the empowerment of local communities or, in other words, to introduce an energetic decentralisation. A researcher then outlines the need to introduce a strong tax system in relationship with carbon emission to support the development of renewable energies. An article then describes the example of the Vendee district which has been developing since 2012 an infrastructure of charging points for electric vehicles. The last article outlines the role of training organisations which will have to adapt themselves to new professions in various sectors

    We have studied the hydrogen bonds in PC{sub 61}BM solids. Inter-molecular interaction is analyzed theoretically for the well-defined monoclinic (P2{sub 1}/n) structure. The results indicate that PC{sub 61}BM combines into C–H⋯O{sub d} bonded molecular chains, where O{sub d} denotes the doubly-bonded O atom of PC{sub 61}BM. The molecular chains are linked together by C–H⋯O{sub s} bonds, where O{sub s} denotes the singly-bonded O atom of PC{sub 61}BM. To reveal the consequences of hydrogen bond formation on the structural properties of PC{sub 61}BM solids (not limited to the monoclinic structure), we design and perform some experiments for annealed samples with the monoclinic (P2{sub 1}/n) PC{sub 61}BM as starting material. The experiments include differential scanning calorimetry, X-ray diffraction and infrared absorption measurements. Structural phase transitions are observed below the melting point. The C–H⋯O{sub d} bonds seem persisting in the altered structures. The inter-molecular hydrogen bonds can help to understand the phase separation in polymer/PC{sub 61}BM blends and may be responsible for the existence of liquid PC{sub 61}BM.

  2. Pulsating proton aurora caused by rising tone Pc1 waves

    Nomura, R.; Shiokawa, K.; Omura, Y.; Ebihara, Y.; Miyoshi, Y.; Sakaguchi, K.; Otsuka, Y.; Connors, M.

    2016-02-01

    We found rising tone emissions with a dispersion of ˜1 Hz per several tens of seconds in the dynamic spectrum of a Pc1 geomagnetic pulsation (Pc1) observed on the ground. These Pc1 rising tones were successively observed over ˜30 min from 0250 UT on 14 October 2006 by an induction magnetometer at Athabasca, Canada (54.7°N, 246.7°E, magnetic latitude 61.7°N). Simultaneously, a Time History of Events and Macroscale Interactions during Substorms panchromatic (THEMIS) all-sky camera detected pulsations of an isolated proton aurora with a period of several tens of seconds, ˜10% variations in intensity, and fine structures of 3° in magnetic longitudes. The pulsations of the proton aurora close to the zenith of ATH have one-to-one correspondences with the Pc1 rising tones. This suggests that these rising tones scatter magnetospheric protons intermittently at the equatorial region. The radial motion of the magnetospheric source, of which the isolated proton aurora is a projection, can explain the central frequency increase of Pc1, but not the shorter period (tens of seconds) frequency increase of ˜1 Hz in Pc1 rising tones. We suggest that EMIC-triggered emissions generate the frequency increase of Pc1 rising tones on the ground and that they also cause the Pc1 pearl structure, which has a similar characteristic time.

    2010-08-01

    Analysis of PC polarimeter data at {radical}s = 200 and 500 GeV from Run9 is presented. Final polarization results, fill-by-fill, for blue and yellow beams, as to be used by RHIC experiments (in collisions) are released and collected in http://www4.rcf.bnl.gov/cnipol/pubdocs/Run09Offline/. Global relative systematic uncertainties {delta}P/P (to be considered as correlated from fill to fill) are 4.7% for 100 GeV beams, and 8.3% (12.1%) for blue (yellow) 250 GeV beams. For a product of two beam polarizations P{sub B} {center_dot} P{sub Y} (used in double spin asymmetry measurements) the relative uncertainty {delta}(P{sub B} {center_dot} P{sub Y})/(P{sub B} {center_dot} P{sub Y}) 8.8% for 100 GeV beams and 18.5% for 250 GeV beams. For the average between two beam polarization (P{sub B} + P{sub Y})/2 (used in single spin asymmetry measurements, when data from two polarized beams are combined) the relative uncertainty is 4.4% for 100 GeV beams and 9.2% for 250 GeV beams. Larger uncertainties for 250 GeV beams relate to significant rate related systematic effects experienced in the first part of Run9 (due to thicker targets used and smaller trans. beam size at higher beam energy).

  5. A TDC-PC based DPAC spectrometer

    International Nuclear Information System (INIS)

    In spectroscopies like muon spin rotation or the time differential perturbed angular correlation method the experimentally determined quantity is a time interval between two events. The transformation of this time into a physically handy signal has in most cases been performed by a time-to-amplitude converter (TAC). The resulting voltage has been digitized in a separate analog-to-digital converter (ADC) and entered some type of multichannel analyser (MCA). Apart from not being very convenient the systems have some significant weaknesses: The available size of the total spectrum area is limited due to the MCA. Nonlinearities in TACs and ADCs and noise in the analog part are well known complications. There is no way to see the experimental result, besides the raw data, during the course of the experiment. Here a new type of data collecting system is described. The basic idea, is to substitute the TAC and EDC for a time-to-digital converter (TDC), that is coupled to a personal computer (PC). The computer, used here, is with 256 kbyte of memory, which is sufficient for both the data collection and for the TDC controlling and data treating program DEPACK. The spectrum area is variable, with a predefined standard size of 8 * 2048 channels. On-line data treatment can be performed with the DEPACK program. With the choice of a TDC all problems related to analog parts in the equipment can be circumvented. The TDC can measure both positive and negative times, which enables in a standard 4 detector setup, the simultaneous collection of 8 spectra. If not objected for other reasons, all fast circuit start and stop signals may access the TDC. Since the maximum conversion frequency of the module is 1 MHz an overload protection is not required

  6. PC/FRAM, Version 3.2 User Manual

    International Nuclear Information System (INIS)

    This manual describes the use of version 3.2 of the PC/FRAM plutonium isotopic analysis software developed in the Safeguards Science and Technology Group, NE-5, Nonproliferation and International Security Division Los Alamos National Laboratory. The software analyzes the gamma ray spectrum from plutonium-bearing items and determines the isotopic distribution of the plutonium 241Am content and concentration of other isotopes in the item. The software can also determine the isotopic distribution of uranium isotopes in items containing only uranium. The body of this manual descenies the generic version of the code. Special facility-specific enhancements, if they apply, will be described in the appendices. The information in this manual applies equally well to version 3.3, which has been licensed to ORTEC. The software can analyze data that is stored in a file on disk. It understands several storage formats including Canberra's S1OO format, ORTEC'S 'chn' and 'SPC' formats, and several ASCII text formats. The software can also control data acquisition using an MCA and then store the results in a file on disk for later analysis or analyze the spectrum directly after the acquisition. The software currently only supports the control of ORTEC MCB'S. Support for Canbema's Genie-2000 Spectroscopy Systems will be added in the future. Support for reading and writing CAM files will also be forthcoming. A versatile parameter fde database structure governs all facets of the data analysis. User editing of the parameter sets allows great flexibility in handling data with different isotopic distributions, interfering isotopes, and different acquisition parameters such as energy calibration, and detector type. This manual is intended for the system supervisor or the local user who is to be the resident expert. Excerpts from this manual may also be appropriate for the system operator who will routinely use the instrument

  8. DORT-PC, 2-D Discrete Ordinates Transport System

    International Nuclear Information System (INIS)

    1 - Description of program or function: This version of DORT (ORNL Mod 5, 12 Oct 89, INEL Ver 2.1) was derived from the Cray UNICOS version distributed in CCC-543/TORT, which was developed at ORNL under Defense Nuclear Agency sponsorship. DORT is directly based on the earlier DOT codes. DORT-PC determines the fluence of particles throughout one- or two-dimensional geometric systems due to sources either generated as a result of particle interaction with the medium or incident upon the system from extraneous sources. The principal application is to the deep-penetration transport of neutrons and photons. Criticality (k-type and search) problems can also be solved. Numerous printed edits of the results are available, and results can be transferred to output files for subsequent analysis. 2 - Method of solution: The Boltzmann transport equation is solved, using either the method of discrete ordinates or diffusion theory approximation. In the discrete ordinates method, the primary mode of operation, balance equations are solved for the flow of particles moving in a set of discrete directions in each cell of a space mesh and in each group of a multigroup energy structure. Iterations are performed until all implicitness in the coupling of cells, directions, groups, and source regeneration has been resolved. Several methods are available to accelerate convergence. Anisotropic cross sections can be expressed in a Legendre expansion of arbitrary order. Output data sets can be used to provide an accurate restart of a previous problem or to deliver information to other codes. Several techniques are available to remove the effects of negative fluxes caused by the finite difference approximation and of negative scattering sources due to truncation of the cross-section expansion. The space mesh can be described such that the number of first-dimensional (i) intervals varies with the second dimension (j). The number of discrete directions can vary across the space mesh and with

    Spratling, M W

    2016-08-01

    Previous work has shown that predictive coding can provide a detailed explanation of a very wide range of low-level perceptual processes. It is also widely believed that predictive coding can account for high-level, cognitive, abilities. This article provides support for this view by showing that predictive coding can simulate phenomena such as categorisation, the influence of abstract knowledge on perception, recall and reasoning about conceptual knowledge, context-dependent behavioural control, and naive physics. The particular implementation of predictive coding used here (PC/BC-DIM) has previously been used to simulate low-level perceptual behaviour and the neural mechanisms that underlie them. This algorithm thus provides a single framework for modelling both perceptual and cognitive brain function. PMID:27118562

    Roop, J.M.; Kaplan, D.T.

    1984-09-01

    A project to improve and enhance the Industrial Sector Technology Use Model (ISTUM) was originated in the summer of 1983. The project had dix identifiable objectives: update the data base; improve run-time efficiency; revise the reference base case; conduct case studies; provide technical and promotional seminars; and organize a service bureau. This interim report describes which of these objectives have been met and which tasks remain to be completed. The most dramatic achievement has been in the area of run-time efficiency. From a model that required a large proportion of the total resources of a mainframe computer and a great deal of effort to operate, the current version of the model (ISTUM-PC) runs on an IBM Personal Computer. The reorganization required for the model to run on a PC has additional advantages: the modular programs are somewhat easier to understand and the data base is more accessible and easier to use. A simple description of the logic of the model is given in this report. To generate the necessary funds for completion of the model, a multiclient project is proposed. This project will extend the industry coverage to all the industrial sectors, including the construction of process flow models for chemicals and petroleum refining. The project will also calibrate this model to historical data and construct a base case and alternative scenarios. The model will be delivered to clients and training provided. 2 references, 4 figures, 3 tables.

    A kind of novel binary phase code named sidelobe suppression code is proposed in this paper. It is defined to be the code whose corresponding optimal sidelobe suppression filter outputs the minimum sidelobes. It is shown that there do exist sidelobe suppression codes better than the conventional optimal codes-Barker codes. For example, the sidelobe suppression code of length 11 with filter of length 39 has better sidelobe level up to 17dB than that of Barker code with the same code length and filter length.

    1997-12-01

    Old seismic data recorded on magnetic tapes is often difficult to read because of the tape sticking problem known as the `sticky syndrome`. It has to be transcribed to other suitable media using dedicated multiple systems during the whole project years. The first system requirement is the capability of reading gapless magnetic tape, which is peculiar to the old seismic data tapes. The second requirement would be the availability of storage devices with compact and huge capacity. The system must be cheap enough compared to the total cost of the data being transcribed. We introduce a PC based seismic data transcribing system. The system is equipped with an tape drive which can handle 800, 1600, 3200, and 6250 BPI densities. Well known storage devices such as 8mm Exabyte, 4mm DDS-2, and the SCSI CD recorder, are selected for the output devices. These output media should provide more durability, compactness, and portability than the original. Linux is chosen for the operating system. Unfortunately, the Linux, like other Unix systems, is subject to the limit in maximum i/o block size. The maximum block size of the SCSI tape driver is fixed to 32 KB, which is far less than the requirements in SEG-A, B, and C seismic tapes. A kernel patch is written to extend such a limit up to 2048 KB. Input and output programs are written to handle the tape data in variable block mode. A unique disk file format is designed to preserve the IBG(inter-block gap) within the disk copy. A utility program is also provided to manipulate the disk copy and to convert to SU(Seismic Unix) compatible SEG-Y file. Of the total two months of the transcription period, we spend most of the time in reading the sticky magnetic tapes. The seismic tapes had to be `baked` to dry out the moisture before reading. It took nine days to burn the all 85 diskettes. Writing two sets of 8mm Exabytes took only one day. It is considered that 8mm Exabyte can be the optimum output media for the main seismic data storage

    Fermilab is investigating the use of PC's for HEP computing. As a first step we have built a full offline environment under Linux on a set of Pentium (P5) and Pentium Pro (P6) machines (the ''PC Farm''). The Pythia simulation has been ported to run serially and in parallel (using CPS) on the PC Farm. Fermilab software products and CDF offline packages have also been ported to Linux. Run 1 CDF data has been analyzed on both Linux and SGI (Irix) with essentially identical results. The performance of the system is compared to results with commercial UNIX systems

It is a PC-compatible FORTRAN code that is written in a top-down, modular format. This paper discusses the additions to the code that permit WECS components to be analyzed using linear fracture mechanics. To illustrate the capabilities of the numerical techniques employed here, two example problems are presented.

  18. Monte Carlo simulation of an arc therapy treatment by means of a PC distribution model

    International Nuclear Information System (INIS)

    It would be always desirable to have an independent assessment of a planning system. Monte Carlo (MC) offers an accurate way of checking dose distribution in non homogeneous volumes. Nevertheless, its main drawback is the long processing times needed. A distribution model to simulate arc-therapy treatments with Monte Carlo techniques has been developed. This model divides the individual tasks with a physical sense. In this way, not only the CPU time is substantially reduced but a detailed analysis can be achieved. A distribution program modifies the input parameters in the code to send a different task to each processor. This model has been installed on a PC network without any resident software. This model works independently of the operating system pre-installed. The PC acting as a server exports the required operating system (Linux), the MC code and the input data, as well as it stores all the results. Some very complex radiosurgery treatments simulated using this model leads a CPU time about one hour. (orig.)

    2010-01-01

    In this paper, we define and study \\emph{quantum cyclic codes}, a generalisation of cyclic codes to the quantum setting. Previously studied examples of quantum cyclic codes were all quantum codes obtained from classical cyclic codes via the CSS construction. However, the codes that we study are much more general. In particular, we construct cyclic stabiliser codes with parameters $[[5,1,3

  20. Abnormal expression and processing of the proprotein convertases PC1 and PC2 in human colorectal liver metastases

    International Nuclear Information System (INIS)

    The family of proprotein convertases has been recently implicated in tumorigenesis and metastasis in animal models. However, these studies have not yet been completely corroborated in human tumors. Using RT PCR, immunoblot and immunohistochemistry we assessed the presence and the processing patterns of the convertases PC1 and PC2 as well as the PC2 specific chaperone 7B2 in human liver metastases originating from colorectal cancer and compared them to unaffected and normal liver. Furthermore, we assessed the presence and processing profiles of PC1, PC2 and 7B2 in primary colon cancers. mRNA, protein expression, and protein cleavage profiles of proprotein convertases 1 and 2 are altered in liver colorectal metastasis, compared to unaffected and normal liver. Active PC1 protein is overexpressed in tumor, correlating with its mRNA profile. Moreover, the enhanced PC2 processing pattern in tumor correlates with the overexpression of its specific binding protein 7B2. These results were corroborated by immunohistochemistry. The specific and uniform convertase pattern observed in the metastases was present only in a fraction of primary colon cancers. The uniformly altered proprotein convertase profile in liver metastases is observed only in a fraction of primary colon cancers, suggesting possible selection processes involving PCs during metastasis as well as an active role of PCs in liver metastasis. In addition, the exclusive presence of 7B2 in metastatic tumors may represent a new target for early diagnosis, prognosis and/or treatment

    Full Text Available The Rt Hon The Lord Phillips of Worth Matravers KG PC, President of the Supreme Court of the United Kingdom of Great Britain and Northern Ireland Ambition and excellence. Those two words epitomize Qatar. Under the leadership of his Highness the Emir, this small State has set out to make an impact on the world that belies its size. Ambitious was the plan to have an international broadcasting station. Ambitious was the plan to build from scratch a Museum of Islamic Art. Ambitious was the bid – the successful bid to host the World Cup in 2022. Ambitious is the bid to stage the Olympic Games in 2020. Qatar not merely has ambitions, it realizes its ambitions. And when it does so it is not enough to say that the result is ‘world class’, for Qatar sets out to be a world leader in whatever it puts its hand to. Excellence is the norm. Al Jazeera has established itself as the broadcasting station of choice for many throughout the world. The Doha Museum of Islamic Art is recognized as being second to none. In addition, the scale and standard of development in Doha itself is setting new standards of excellence in the fields of architecture and civil engineering. Thus when Qatar focuses its energies on education and the law, high achievements are expected. I shall have the honour of helping to achieve those expectations when I succeed Lord Woolf as President of Qatar’s new and impressive Civil and Commercial Court. The College of Law at Qatar University is already achieving excellence in the field of legal education. So, naturally, all expect great things of this new International Review of Law and I am delighted to have been invited to welcome it by this foreword. The range of the first edition is both international and topical. Those countries that have experienced the turbulence of the Arab Spring are settling new constitutions, and other countries are bent on constitutional reform designed to avoid such turbulence.

    The autocorrelation of a Boolean function possesses the capability to reflect such characteristics as linear structure, Strict Avalanche Criterion(SAC) and Propagation Criterion(PC)of degree k. But it can do nothing in determining the order of SAC or PC. A calculating table for the autocorrelation is constructed in this paper so as to show what is beyond the autocorrelation and how the three cryptographic characteristics are exhibited. A deeper study on the calculating table in a similar way has helped us to develop a new concept, named as the general autocorrelation, to address efficiently the problem how to determine the orders of SAC and PC. The application on the Advanced Encryption Standard(AES) shows the SAC and PC characteristics of Boolean functions of AES S-box.

    Crown rust is an important disease of oat caused by Puccinia coronata Corda f. sp. avenae Eriks. Crown rust is efficiently and effectively managed through the development of resistant oat varieties. Pc91 is a seedling crown rust resistance gene that is highly effective against the current P. coronata population in North America. The primary objective of this study was to develop DNA markers linked to Pc91 for purposes of marker-assisted selection in oat breeding programs. The Pc91 locus was mapped using a population of F7-derived recombinant inbred lines developed from the cross 'CDC Sol-Fi'/'HiFi' made at the Crop Development Centre, University of Saskatchewan. The population was evaluated for reaction to P. coronata in field nurseries in 2008 and 2009. Pc91 mapped to a linkage group consisting of 44 Diversity Array Technology (DArT) markers. DArTs were successfully converted to sequence characterized amplified region (SCAR) markers. Five robust SCARs were developed from three non-redundant DArTs that co-segregated with Pc91. SCAR markers were developed for different assay systems, such that SCARs are available for agarose gel electrophoresis, capillary electrophoresis, and Taqman single nucleotide polymorphism detection. The SCAR markers accurately postulated the Pc91 status of 23 North American oat breeding lines. PMID:20862449

    Full Text Available Interface properties of cobalt(II phthalocyanine (CoPc and cobalt(II hexadecafluoro-phthalocyanine (CoPcF16 to gold are investigated by photo-excited electron spectroscopies (X-ray photoemission spectroscopy (XPS, ultraviolet photoemission spectroscopy (UPS and X-ray excited Auger electron spectroscopy (XAES. It is shown that a bidirectional charge transfer determines the interface energetics for CoPc and CoPcF16 on Au. Combined XPS and XAES measurements allow for the separation of chemical shifts based on different local charges at the considered atom caused by polarization effects. This facilitates a detailed discussion of energetic shifts of core level spectra. The data allow the discussion of site-specific charge-transfer processes.

    Quantum convolutional codes can be used to protect a sequence of qubits of arbitrary length against decoherence. We introduce two new families of quantum convolutional codes. Our construction is based on an algebraic method which allows to construct classical convolutional codes from block codes, in particular convolutional BCH codes. These codes have the property that they contain their Euclidean, respectively Hermitian, dual codes. Hence, they can be used to define quantum convolutional codes by the stabilizer code construction. We compute BCH-like bounds on the free distances which can be controlled as in the case of block codes, and establish that the codes have non-catastrophic encoders.

    necessary only to add an identification record and the namelist data that are to be changed from the previous run. This code was originally developed in 1989 in FORTRAN V on a CDC 6000 computer system, and was later ported to an MS-DOS environment. Both versions are available from COSMIC. There are only a few differences between the PC version (LAR-14458) and CDC version (LAR-14178) of AERO2S distributed by COSMIC. The CDC version has one main source code file while the PC version has two files which are easier to edit and compile on a PC. The PC version does not require a FORTRAN compiler which supports NAMELIST because a special INPUT subroutine has been added. The CDC version includes two MODIFY decks which can be used to improve the code and prevent the possibility of some infrequently occurring errors while PC-version users will have to make these code changes manually. The PC version includes an executable which was generated with the Ryan McFarland/FORTRAN compiler and requires 253K RAM and an 80x87 math co-processor. Using this executable, the sample case requires about four hours to execute on an 8MHz AT-class microcomputer with a co-processor. The source code conforms to the FORTRAN 77 standard except that it uses variables longer than six characters. With two minor modifications, the PC version should be portable to any computer with a FORTRAN compiler and sufficient memory. The CDC version of AERO2S is available in CDC NOS Internal format on a 9-track 1600 BPI magnetic tape. The PC version is available on a set of two 5.25 inch 360K MS-DOS format diskettes.

    The recent advancement of computer technology makes reservoir simulations feasible in a personal computer (PC) environment. This manual provides a guide for running BOAST-VHS, a black oil reservoir simulator for vertical/horizontal/slant wells, using a PC. In addition to detailed explanations of input data file preparation for simulation runs, special features of BOAST-VHS are described and three sample problems are presented. BOAST-VHS is a cost-effective and easy-to-use reservoir simulation tool for the study of oil production from primary depletion and waterflooding in a black oil reservoir. The well model in BOAST-VHS permits specification of any combination of horizontal, slanted, and vertical wells in the reservoir. BOAST-VHS was designed for an IBM PC/AT, PS-2, or compatible computer with 640 K bytes of memory. BOAST-VHS can be used to model a three-dimensional reservoir of up to 810 grid blocks with any combination of rows, columns, and layers, depending on the input data supplied. This dynamic redimensioning feature facilitates simulation work by avoiding the need to recompiling the simulator for different reservoir models. Therefore the program is only supplied as executable code without any source code.

  18. Study of nuclear computer code maintenance and management system

    International Nuclear Information System (INIS)

    Software maintenance is one of the most important problems since late 1970's.We wish to develop a nuclear computer code system to maintenance and manage KAERI's nuclear software. As a part of this system, we have developed three code management programs for use on CYBER and PC systems. They are used in systematic management of computer code in KAERI. The first program is embodied on the CYBER system to rapidly provide information on nuclear codes to the users. The second and the third programs were embodied on the PC system for the code manager and for the management of data in korean language, respectively. In the requirement analysis, we defined each code, magnetic tape, manual and abstract information data. In the conceptual design, we designed retrieval, update, and output functions. In the implementation design, we described the technical considerations of database programs, utilities, and directions for the use of databases. As a result of this research, we compiled the status of nuclear computer codes which belonged KAERI until September, 1988. Thus, by using these three database programs, we could provide the nuclear computer code information to the users more rapidly. (Author)

  19. Empirically modelled Pc3 activity based on solar wind parameters

    Directory of Open Access Journals (Sweden)

    T. Raita

    2010-09-01

    Full Text Available It is known that under certain solar wind (SW/interplanetary magnetic field (IMF conditions (e.g. high SW speed, low cone angle the occurrence of ground-level Pc3–4 pulsations is more likely. In this paper we demonstrate that in the event of anomalously low SW particle density, Pc3 activity is extremely low regardless of otherwise favourable SW speed and cone angle. We re-investigate the SW control of Pc3 pulsation activity through a statistical analysis and two empirical models with emphasis on the influence of SW density on Pc3 activity. We utilise SW and IMF measurements from the OMNI project and ground-based magnetometer measurements from the MM100 array to relate SW and IMF measurements to the occurrence of Pc3 activity. Multiple linear regression and artificial neural network models are used in iterative processes in order to identify sets of SW-based input parameters, which optimally reproduce a set of Pc3 activity data. The inclusion of SW density in the parameter set significantly improves the models. Not only the density itself, but other density related parameters, such as the dynamic pressure of the SW, or the standoff distance of the magnetopause work equally well in the model. The disappearance of Pc3s during low-density events can have at least four reasons according to the existing upstream wave theory: 1. Pausing the ion-cyclotron resonance that generates the upstream ultra low frequency waves in the absence of protons, 2. Weakening of the bow shock that implies less efficient reflection, 3. The SW becomes sub-Alfvénic and hence it is not able to sweep back the waves propagating upstream with the Alfvén-speed, and 4. The increase of the standoff distance of the magnetopause (and of the bow shock. Although the models cannot account for the lack of Pc3s during intervals when the SW density is extremely low, the resulting sets of optimal model inputs support the generation of mid latitude Pc3 activity predominantly through

  20. REPRISK-PC, Radioactive Waste Storage Risk Assessment

    International Nuclear Information System (INIS)

    A - Description of program or function: REPRISK-PC is a PC version of the REPRISK model used in the modelling of long-term radionuclide releases and population health effects resulting from disposal of high level radioactive wastes in mined geological repositories. REPRISK is a set of computer programs and databases that models the transport of radionuclides from the repository through the environment to exposed human populations and estimates the resulting health impact. B - Method of solution: Various natural processes or human activities could lead to radionuclide releases from a geological repository after it has been closed. These perturbations happen according to some frequency or probability. REPRISK-PC incorporates the characteristics of these perturbations and their associated probability. REPRISK-PC models four release scenarios: (1) direct impact of a waste package - releases to air and land surface (volcano, meteorite, drilling/direct hit); (2) direct impact of a waste package - releases to an aquifer (faulting, breccia pipes); (3) disruption of the repository - releases to land (drilling/no hit); (4) disruption of the repository - releases to an aquifer (normal groundwater flow, faulting, breccia pipes, drilling/no hit). C - Restrictions on the complexity of the problem: REPRISK-PC does not model the differences in radionuclide-specific velocities, which may control the travel time from repository to the accessible environment. It is not a good model for time periods greater than 10,000 years when radium daughters become important

    We introduce twisted permutation codes, which are frequency permutation arrays analogous to repetition permutation codes, namely, codes obtained from the repetition construction applied to a permutation code. In particular, we show that a lower bound for the minimum distance of a twisted permutation code is the minimum distance of a repetition permutation code. We give examples where this bound is tight, but more importantly, we give examples of twisted permutation codes with minimum distance...

    This project involved the installation of a 200kW PC25C{trademark} phosphoric-acid fuel cell power plant at Orgenergogaz, a Gazprom industrial site in Russia. In April 1997, a PC25C{trademark} was sold by ONSI Corporation to Orgenergogaz, a subsidiary of the Russian company ''Gazprom''. Due to instabilities in the Russian financial markets, at that time, the unit was never installed and started by Orgenergogaz. In October of 2001 International Fuel Cells (IFC), now known as UTC Fuel Cells (UTCFC), received a financial assistance award from the United States Department of Energy (DOE) entitled ''Demonstration of PC 25 Fuel Cell in Russia''. Three major tasks were part of this award: the inspection of the proposed site and system, start-up assistance, and installation and operation of the powerplant.

    Dubey, Girija; Jindal, Prashant; Bhandari, Rajiv; Dhiman, Neha; Bajaj, Chetan; Jindal, Vijay

    Poly methyl methacrylate (PMMA) and Polycarbonate (PC) are low cost polymer materials which can be easily transformed into desired shapes for various applications. However they have poor mechanical, thermal and electrical properties which are required to be enhanced to widen their scope of applications specifically where along with high strength, rapid heat transfer is essential. Multi Walled Carbon nanotubes (MWCNTs) are excellent new materials having extraordinary mechanical and transport properties. We will report results of fabricating composites of varying compositions of MWCNTs with PMMA and PC and their thermal conductivity behaviour using simple transient heat flow methods. The samples in disk shapes of around 2 cm diameters and 0.2 cm thickness with MWCNT compositions varying up to 10 wt% were fabricated. We found that both PMMA and PC measured high thermal conductivity with increase in the composition of CNTs. The thermal conductivity of 10wt% MWCNT/PMMA composite increased by nearly two times in comparison to pure PMMA.

  7. Monte Carlo Simulation for Neptun 10 PC medical linear accelerator and calculations of electron beam parameters

    International Nuclear Information System (INIS)

    In recent decades, cancer has been one of the main ever increasing causes of death in developed countries. In order to fulfill the aforementioned considerations different techniques have been used, one of which is Monte Carlo simulation technique. High accuracy of the Monte Carlo simulation has been one of the main reason for its wide spread application. In this study, MCNP-4C code was employed to simulate electron mode of the Neptun 10 PC Linac, dosimetric quantities for conventional fields have also been both measured and calculated. Although Neptun 10 PC Linac is no longer licensed for installation in European and some other countries but regrettably nearly 10 of them have been installed in different centers around the country and are in operation. Therefore, in this circumstance, to improve the accuracy of treatment planning, Monte Carlo simulation for Neptun 10 PC was recognized as a necessity. Simulated and measured values of depth dose curves, off axis dose distributions for 6 , 8 and 10 MeV electrons applied for four different size fields, 6 x 6 cm2, 10 x 10 cm2, 15 x 15 cm2 and 20 x 20 cm2 were obtained. The measurements were carried out by a Welhofer-Scanditronix dose scanning system, Semiconductor Detector and Ionization Chamber. The results of this study have revealed that the values of two main dosimetric quantities depth dose curves and off axis dose distributions, acquired by MCNP-4C simulation and the corresponding values achieved by direct measurements are in a very good agreement (within 1% to 2% difference). In general, very good consistency of simulated and measured results, is a good proof that the goal of this work has been accomplished. In other word where measurements of some parameters are not practically achievable, MCNP-4C simulation can be implemented confidently. (author)

  8. Homological stabilizer codes

    International Nuclear Information System (INIS)

    In this paper we define homological stabilizer codes on qubits which encompass codes such as Kitaev’s toric code and the topological color codes. These codes are defined solely by the graphs they reside on. This feature allows us to use properties of topological graph theory to determine the graphs which are suitable as homological stabilizer codes. We then show that all toric codes are equivalent to homological stabilizer codes on 4-valent graphs. We show that the topological color codes and toric codes correspond to two distinct classes of graphs. We define the notion of label set equivalencies and show that under a small set of constraints the only homological stabilizer codes without local logical operators are equivalent to Kitaev’s toric code or to the topological color codes. - Highlights: ► We show that Kitaev’s toric codes are equivalent to homological stabilizer codes on 4-valent graphs. ► We show that toric codes and color codes correspond to homological stabilizer codes on distinct graphs. ► We find and classify all 2D homological stabilizer codes. ► We find optimal codes among the homological stabilizer codes.

In brief, the analysis consists of calibrating the detectors, determining energy corrections ('dead layers'), determining good runs and extracting the polarization from data.

  10. PC-based digital feedback control for scanning force microscope

    International Nuclear Information System (INIS)

    In the past, most digital feedback implementation for scanned-probe microscope were based on a digital signal processor (DSP). At present DSP plug-in card with the input-output interface module is still expensive compared to a fast pentium PC motherboard. For a magnetic force microscope (MFM) digital feedback has an advantage where the magnetic signal can be easily separated from the topographic signal. In this paper, a simple low-cost PC-based digital feedback and imaging system for Scanning Force Microscope (SFM) is presented. (Author)

  11. ISO-PC Version 1.98: User's guide

    International Nuclear Information System (INIS)

    This document describes how to use Version 1.98 of the shielding program named ISO-PC. Version 1.98 corrects all known errors in ISOSHLD-II. In addition, a few numeric problems have been eliminated. There are three new namelist variables, 25 additional shielding materials, and 5 more energy groups. The two major differences with the original ISOSHLD-II are the removal of RIBD(radioisotope buildup and decay) source generator, and the removal of the non-uniform source distribution parameter, SSV1. This version of ISO-PC works with photon energies from 10 KeV to 10 MeV using 30 energy groups

  15. STATUS OF THE LINUX PC CLUSTER FOR BETWEEN-PULSE DATA ANALYSES AT DIII-D

    International Nuclear Information System (INIS)

    OAK-B135 Some analyses that survey experimental data are carried out at a sparse sample rate between pulses during tokamak operation and/or completed as a batch job overnight because the complete analysis on a single fast workstation cannot fit in the narrow time window between two pulses. Scientists therefore miss the opportunity to use these results to guide experiments quickly. With a dedicated Beowulf type cluster at a cost less than that of a workstation, these analyses can be accomplished between pulses and the analyzed data made available for the research team during the tokamak operation. A Linux PC cluster comprises of 12 processors was installed at DIII-D National Fusion Facility in CY00 and expanded to 24 processors in CY01 to automatically perform between-pulse magnetic equilibrium reconstructions using the EFIT code written in Fortran, CER analyses using CERQUICK code written in IDL and full profile fitting analyses (ne, Te, Ti, Vr, Zeff) using IDL code ZIPFIT.

  17. The code system COROUT: Radioactive inventory calculations

    International Nuclear Information System (INIS)

    The code system COROUT is devoted to the evaluation of nuclear reactor out-of-core radioactive inventory for the sake of the nuclear power plant decommissioning problem. The code includes calculations of the neutron flux distributions and activation kinetics in the consistent way. Only thermal neutrons are taken into consideration in the present code version. Code is divided into three steps. The first step prepares the necessary data file containing data on reactor geometry, core flux, reactor operational history and data on elements in the out-of-core zones. The main part of calculations are performed during the second step. Here the thermal neutron flux distribution in the out-of-core area is calculated for two-dimensional cylindrical geometry and the system of gain-loss equations and the activation kinetics is solved for the elements in the different out-of-core shells. The Vladimirov's method of iterations on the spatial grid is used for the neutron flux calculations. The kinetic equations are solved by the operational method. The change of neutron field due to activation during reactor campaign is taken into account. The third part of COROUT code system allows to prepare plots of flux and activity distribution for different shells. All steps could be initiated independently using the results stored at the previous steps. The code is destined for the personal computers and has been written on the base of 32-bit FORTRAN language for IBM PC. 4 refs, 6 figs, 1 tab

    Recent publications have described the implementation of state-of-the-art reservoir engineering applications based on integrated networks of mainframe, workstation, and desktop computers. These facilities provide excellent resources for geologic and engineering applications, but at the cost of substantial investment in computer hardware, network installation, and systems staffing. This paper describes an adaptation of similar state-of-the-art applications to a desktop platform that minimizes the required hardware and system investment. The platform is an Intel 486 or Pentium-based PC with two hard drives and 32 to 64 MB of memory. One disk is partitioned to a standard DOS/Windows environment. The other disk is partitioned to the Linux operating system. Linux is a freely available clone of Unix for the 80386/80486 CPU, which is supported by a worldwide volunteer effort. A machine of this type can be constructed from components for $4,000 to $8,000, depending on CPU and memory. A number of proprietary modeling codes have been ported over so that the PC can provide much of the capability of the network systems.

    2012-08-01

    Rice stripe virus (RSV) belongs to the genus Tenuivirus and its genome consists of four single-stranded RNAs encoding seven proteins. Here, we have analyzed the processing and membrane association of Pc2 encoded by vcRNA2 in insect cells. The enhanced green fluorescent protein (eGFP) was fused to the Pc2 and used for the detection of Pc2 fusion proteins. The results showed that Pc2 was cleaved to produce two proteins named Pc2-N and Pc2-C. When expressed alone, either Pc2-N or Pc2-C could transport to the Endoplasmic reticulum (ER) membranes independently. Further mutagenesis studies revealed that Pc2 contained three ER-targeting domains. The results led us to propose a model for the topology of the Pc2 in which an internal signal peptide immediately followed a cleavage site, and two transmembrane regions are contained.

    An experimental setup is described to measure 1/f noise (pink noise) in conductors using a PC equipped with a sound card functioning as a spectrum analyzer. A simple auxiliary analog electronic circuit with three operational amplifiers has been assembled to yield the required amplification, to match the sound card signal levels, and to implement a bridge configuration to improve dynamical range. Test experiments and data analysis have been conducted using commonly available software, together with some custom scripts and C code. The whole setup is technically accessible and economical for both the high school and undergraduate levels. Results are reported for pink noise of vintage carbon resistors spanning seven frequency decades, from 1 mHz to 10 kHz.

  2. Proposal for Using of a PC for Data Acquisition, Signal Processing and Control of Egyptor Tokamak

    International Nuclear Information System (INIS)

    This paper presents a system to replace the outdated and faulty computer associated with Egyptor Tokamak by a conventional PC and I/O card to restore its automatic data acquisition and control. VisSim S/W with real-time add-on and Advantech PCL-812 PG compatible ACL-812 PG data acquisition card are employed to achieve this purpose. Digital channels of the card are buffered to drive the Tokamak associated circuits. A multi-mode program for data acquisition and control is designed and implemented in VisSim environment. Data analysis is also included in the program. The program can be distributed with VisSim viewer or through generated C code from VisSim block diagram. The proposed system is tested on Tokamak successfully for working relay and thyristor driving circuits

  3. A PC-based computer program for simulation of containment pressurization

    International Nuclear Information System (INIS)

    This paper reports that a PC-based computer program has been developed to simulate a pressurized water reactor (PWR) containment during various transients. This containment model is capable of determining pressure and temperature history of a PWR containment in the event of a loss of coolant accident, as well as main steam line breaks inside the containment. Conservation of mass and energy equations are applied to the containment model. Development of the program is based on minimization of input specified information and user friendliness. Maximization of calculation efficiency is obtained by superseding the traditional trial and error procedure for determination of the state variables and implementation of an explicit solution for pressure. The program includes simplified models for active heat removal systems. The results are in close agreement between the present model and CONTEMPT-MOD5 computer code for pressure and temperature inside the containment

    2001-04-01

    Prohormone convertases PC1 and PC2 are endoproteases involved in prohormone cleavage at pairs of basic amino acids. There is a report that prohormone convertase exists in the rat anterior pituitary gonadotrophs, where it had previously been considered that proprotein processing does not take place. In addition to luteinizing hormone and follicle-stimulating hormone, rat pituitary gonadotrophs contain chromogranin A (CgA) and secretogranin II (SgII), two members of the family of granin proteins, which have proteolytic sites in their molecules. In the present study we examined whether there is a close correlation between subcellular localization of prohormone convertases and granin proteins. Ultrathin sections of rat anterior pituitary were immunolabeled with anti-PC1 or -PC2 antisera and then stained with immunogold. Immunogold particles for PC1 were exclusively found in large, lucent secretory granules, whereas those for PC2 were seen in both large, lucent and small, dense granules. The double-immunolabeling also demonstrated colocalization of PC2 and SgII in small, dense granules and of PC1, PC2, and CgA in large, lucent granules. These immunocytochemical results suggest that PC2 may be involved in the proteolytic processing of SgII and that both PC1 and PC2 may be necessary to process CgA. PMID:11383885

    This work consists about the progress made on the design and development of a new optimized version of DART code (DART-P), a mechanistic computer model for the performance calculation and assessment of aluminum dispersion fuel. It is part of a collaboration agreement between CNEA and ANL in the area of Low Enriched Uranium Advanced Fuels. It is held by the Implementation Arrangement for Technical Exchange and Cooperation in the Area of Peaceful Uses of Nuclear Energy, signed on October 16, 1997 between US DOE and the National Atomic Energy Commission of the Argentine Republic. DART optimization is a biannual program; it is operative since February 8, 1999 and has the following goals: 1. Design and develop a new DART calculation kernel for implementation within a parallel processing architecture. 2. Design and develop new user-friendly I/O routines to be resident on Personal Computer (PC)/WorkStation (WS) platform. 2.1. The new input interface will be designed and developed by means of a Visual interface, able to guide the user in the construction of the problem to be analyzed with the aid of a new database (described in item 3, below). The new I/O interface will include input data check controls in order to avoid corrupted input data. 2.2.

  8. Experiences with NJOY and ENDF pre-processing system on PC-486 and benchmarks of WIMS library generated from ENDF/B-VI

    International Nuclear Information System (INIS)

    The objective of the present study is to develop WIMS-CITATION computation system using PC-486 for nuclear analysis of advanced Pressurized Water Reactors, whose burnups are designed to achieve more than 60,000 MWD/MTU, and CANDU reactors. In order to achieve the objective, it is essential to generate the proper WIMS library. The possibility of employing NJOY code and ENDF Pre-Processing System are under investigation. In order to verify the acceptability of the WIMS library generated from ENDF/B-VI on PC-486, new libraries are generated and compared with the libraries generated using CYBER and SUN Work Station for testing benchmark results of five light water and five heavy water lattices. The result shows that PC-486-based WIMS library is acceptable even though there exist some minor problems. (author). 11 refs, 16 figs, 9 tabs

    Full Text Available Background: Platelet rich plasma-platelet concentrate (PRP-PC, buffy coat poor-platelet concentrate (BC-PC, and apheresis-PC were prepared and their quality parameters were assessed. Study Design: In this study, the following platelet products were prepared: from random donor platelets (i platelet rich plasma - platelet concentrate (PRP-PC, and (ii buffy coat poor- platelet concentrate (BC-PC and (iii single donor platelets (apheresis-PC by different methods. Their quality was assessed using the following parameters: swirling, volume of the platelet concentrate, platelet count, WBC count and pH. Results: A total of 146 platelet concentrates (64 of PRP-PC, 62 of BC-PC and 20 of apheresis-PC were enrolled in this study. The mean volume of PRP-PC, BC-PC and apheresis-PC was 62.30±22.68 ml, 68.81±22.95 ml and 214.05±9.91 ml and ranged from 22-135 ml, 32-133 ml and 200-251 ml respectively. The mean platelet count of PRP-PC, BC-PC and apheresis-PC was 7.6±2.97 x 1010/unit, 7.3±2.98 x 1010/unit and 4.13±1.32 x 1011/unit and ranged from 3.2-16.2 x 1010/unit, 0.6-16.4 x 1010/unit and 1.22-8.9 x 1011/unit respectively. The mean WBC count in PRP-PC (n = 10, BC-PC (n = 10 and apheresis-PC (n = 6 units was 4.05±0.48 x 107/unit, 2.08±0.39 x 107/unit and 4.8±0.8 x 106/unit and ranged from 3.4 -4.77 x 107/unit, 1.6-2.7 x 107/unit and 3.2 - 5.2 x 106/unit respectively. A total of 26 units were analyzed for pH changes. Out of these units, 10 each were PRP-PC and BC-PC and 6 units were apheresis-PC. Their mean pH was 6.7±0.26 (mean±SD and ranged from 6.5 - 7.0 and no difference was observed among all three types of platelet concentrate. Conclusion: PRP-PC and BC-PC units were comparable in terms of swirling, platelet count per unit and pH. As expected, we found WBC contamination to be less in BC-PC than PRP-PC units. Variation in volume was more in BC-PC than PRP-PC units and this suggests that further standardization is required for preparation of BC-PC

    We cloned cDNAs encoding PC1 and PC2 from a cDNA library constructed for the anterior pituitary gland of the bullfrog (Rana catesbeiana) and sequenced them. The bullfrog PC1 cDNA consisted of 2972 base pairs (bp) with an open reading frame of 2208 bp and encoded a protein of 736 amino acids, including a putative signal peptide of 26 amino acids. The protein showed a high homology to R. ridibunda PC1 (95.1%) and mammalian PC1 (72.6%). The bullfrog PC2 cDNA consisted of 2242 bp with an open reading frame of 1914 bp and encoded a protein of 638 amino acids, including a putative signal peptide of 23 amino acids. This protein showed a high homology to R. ridibunda PC2 (95.5%) and mammalian PC2 (84.8%). The catalytic triad of serine proteinases of the subtilisin family was found at Asp-168, His-209, and Ser-383 in the PC1 protein and at Asp-167, His-208, and Ser-384 in the PC2 protein. In situ hybridization staining revealed that PC2 mRNA was detected in corticotrope cells of the tadpoles, but not in those of the adults. In the adult, only PC1 mRNA was detected in the pars distalis but both PC1 and PC2 mRNAs were detected in the pars intermedia. The data also showed that PC1 mRNA was expressed in gonadotrope cells.

    Highlights: •Cadmium can promote early upregulation of autophagy in PC-12 cells. •Autophagy precedes apoptosis in cadmium-treated PC-12 cells. •Cadmium-induced autophagy is cytoprotective in PC-12 cells. •Class III PI3K/beclin-1/Bcl-2 signaling pathway plays a positive role in cadmium-triggered autophagy. -- Abstract: Laboratory data have demonstrated that cadmium (Cd) may induce neuronal apoptosis. However, little is known about the role of autophagy in neurons. In this study, cell viability decreased in a dose- and time-dependent manner after treatment with Cd in PC-12 cells. As cells were exposed to Cd, the levels of LC3-II proteins became elevated, specific punctate distribution of endogenous LC3-II increased, and numerous autophagosomes appeared, which suggest that Cd induced a high level of autophagy. In the late stages of autophagy, an increase in the apoptosis ratio was observed. Likewise, pre-treatment with chloroquine (an autophagic inhibitor) and rapamycin (an autophagic inducer) resulted in an increased and decreased percentage of apoptosis in contrast to other Cd-treated groups, respectively. The results indicate that autophagy delayed apoptosis in Cd-treated PC-12 cells. Furthermore, co-treatment of cells with chloroquine reduced autophagy and cell activity. However, rapamycin had an opposite effect on autophagy and cell activity. Moreover, class III PI3 K/beclin-1/Bcl-2 signaling pathways served a function in Cd-induced autophagy. The findings suggest that Cd can induce cytoprotective autophagy by activating class III PI3 K/beclin-1/Bcl-2 signaling pathways. In sum, this study strongly suggests that autophagy may serve a positive function in the reduction of Cd-induced cytotoxicity.

In sum, this study strongly suggests that autophagy may serve a positive function in the reduction of Cd-induced cytotoxicity

    2008-08-01

    Full Text Available We present a new class of alternating codes. Instead of the customary binary phase codes, the new codes utilize either p or p–1 phases, where p is a prime number. The first class of codes has code length pm, where m is a positive integer, the second class has code length p–1. We give an actual construction algorithm, and explain the principles behind it. We handle a few specific examples in detail. The new codes offer an enlarged collection of code lengths for radar experiments.

    Highlights: • Coupling interface between CFD code Fluent and system code Athlet was created. • Athlet code is internally coupled with neutron kinetic code Dyn3D. • Explicit coupling of overlapped computational domains was used. • A coupled system of Athlet/Dyn3D+Fluent codes was successfully tested on a real case. - Abstract: The aim of this work was to develop the coupling interface between CFD code Fluent and system code Athlet internally coupled with neutron kinetic code Dyn3D. The coupling interface is intended for simulation of complex transients such as Main Steam Line Break scenarios, which cannot be modeled separately first by system and neutron kinetic code and then by CFD code, because of the feedback between the codes. In the first part of this article, the coupling method is described. Explicit coupling of overlapped computational domains is used in this work. The second part of the article presents a demonstration simulation performed by the coupled system of Athlet/Dyn3D and Fluent. The “Opening a Steam Dump to the Atmosphere” test carried out at the Temelin NPP (VVER-1000) was simulated by the coupled system. In this simulation, the primary and secondary circuits were modeled by Athlet, mixing in downcomer and lower plenum was simulated by Fluent and heat generation in the core was calculated by Dyn3D. The results of the simulation with Athlet/Dyn3D+Fluent were compared with the experimental data and the results from a calculation performed with Athlet/Dyn3D without Fluent.

    The genes for three subtilisin/kexin-like proprotein convertases, PC4, PC5, and PACE4, were mapped in the mouse by RFLP analysis of a DNA panel from a (C57BL/6JEi x SPRET/Ei) F{sub 1} x SPRET/Ei backcross. The chromosomal locations of the human homologs were determined by Southern blot analysis of a DNA panel from human-rodent somatic cell hybrids, most of which contained a single human chromosome each. The gene for PC4 (Pcsk4 locus) mapped to mouse chromosome 10, close to the Adn (adipsin, a serine protease) locus and near the Amh (anti-Mullerian hormone) locus; in a human, the gene was localized to chromosome 19. The gene for PC5 (Pcsk5 locus) mapped to mouse chromosome 19 close to the Lpc1 (lipoacortin-1) locus and, in human, was localized to chromosome 9. The gene for PACE4 (Pcsk6 locus) mapped to mouse chromosome 7, at a distance of 13 cM from the Pcsk3 locus, which specifies furin, another member of this family of enzymes previoulsy mapped to this chromosome. This is in concordance with the known close proximity of these two loci in the homologous region on human chromosome 15q25-qter. Pcsk3 and Pcsk6 mapped to a region of mouse chromosome 7 that has been associated cytogenetically with postnatal lethality in maternal disomy, suggesting that these genes might be candidates for imprinting. 43 refs., 3 figs., 2 tabs.

    2015-01-01

    A novel surface-type nonvolatile electric memory elements based on organic semiconductors CuPc and H2Pc are fabricated by vacuum deposition of the CuPc and H2Pc films on preliminary deposited metallic (Ag and Cu) electrodes. The gap between Ag and Cu electrodes is 30–40 µm. For the current–voltage (I–V ) characteristics the memory effect, switching effect, and negative differential resistance regions are observed. The switching mechanism is attributed to the electric-field-induced charge transfer. As a result the device switches from a low to a high-conductivity state and then back to a low conductivity state if the opposite polarity voltage is applied. The ratio of resistance at the high resistance state to that at the low resistance state is equal to 120–150. Under the switching condition, the electric current increases∼80–100 times. A comparison between the forward and reverse I–V characteristics shows the presence of rectifying behavior.

  12. Teseo code validation

    International Nuclear Information System (INIS)

    In this report some validation tests for the TESEO code are described. The TESEO code was developed at ENEA - Clementel Center in the framework of the C2RV code sequence. This code sequence produces multigroup resonance cross sections for fast reactor analysis. It consists of the codes TESEO, MC2-II, GERES, ANISN, MEDIL. The TESEO code processes basic nuclear data in ENDF-B format and produces an ultrafine group (2082 groups) cross section library for the MC2-II code. To validate the TESEO algorithms, the data produced by TESEO code were compared with the data produced by other well-tested codes which use different algorithms. No substantial differences was found between these data and the data produced by TESEO code. TESEO algorithms showed high reliability. A detailed study of TESEO calculation options was carried out. Their use and functions are shown to inform the user of the code

    Science.gov (United States)

    Riley, , .

    1994-01-01

    The C Language Integrated Production System, CLIPS, is a shell for developing expert systems. It is designed to allow artificial intelligence research, development, and delivery on conventional computers. The primary design goals for CLIPS are portability, efficiency, and functionality. For these reasons, the program is written in C. CLIPS meets or outperforms most micro- and minicomputer based artificial intelligence tools. CLIPS is a forward chaining rule-based language. The program contains an inference engine and a language syntax that provide a framework for the construction of an expert system. It also includes tools for debugging an application. CLIPS is based on the Rete algorithm, which enables very efficient pattern matching. The collection of conditions and actions to be taken if the conditions are met is constructed into a rule network. As facts are asserted either prior to or during a session, CLIPS pattern-matches the number of fields. Wildcards and variables are supported for both single and multiple fields. CLIPS syntax allows the inclusion of externally defined functions (outside functions which are written in a language other than CLIPS). CLIPS itself can be embedded in a program such that the expert system is available as a simple subroutine call. Advanced features found in CLIPS version 4.3 include an integrated microEMACS editor, the ability to generate C source code from a CLIPS rule base to produce a dedicated executable, binary load and save capabilities for CLIPS rule bases, and the utility program CRSV (Cross-Reference, Style, and Verification) designed to facilitate the development and maintenance of large rule bases. Five machine versions are available. Each machine version includes the source and the executable for that machine. The UNIX version includes the source and binaries for IBM RS/6000, Sun3 series, and Sun4 series computers. The UNIX, DEC VAX, and DEC RISC Workstation versions are line oriented.

  14. Calculations of angular momentum coupling coefficients on a computer code

    International Nuclear Information System (INIS)

    In this study, Clebsch-Gordan coefficients, 3j symbols, Racah coefficients, Wigner's 6j and 9j symbols were calculated by a prepared computer code of COEFF. The computer program COEFF is described which calculates angular momentum coupling coefficients and expresses them as quotient of two integers multiplied by the square root of the quotient of two integers. The program includes subroutines to encode an integer into its prime factors, to decode of prime factors back into an integer , to perform basic arithmetic operations on prime-coded numbers, as well as subroutines which calculate the coupling coefficients themselves. The computer code COEFF had been prepared to run on a VAX. In this study we rearranged the code to run on PC and tested it successfully. The obtained values in this study, were compared with the values of other computer programmes. A pretty good agreement is obtained between our prepared computer code and other computer programmes

  15. METHANE de-NOX for Utility PC Boilers

    Energy Technology Data Exchange (ETDEWEB)

    2005-09-30

    The overall project objective is the development and validation of an innovative combustion system, based on a novel coal preheating concept prior to combustion, that can reduce NO{sub x} emissions to 0.15 lb/million Btu or less on utility pulverized coal (PC) boilers. This NO{sub x} reduction should be achieved without loss of boiler efficiency or operating stability, and at more than 25% lower levelized cost than state-of-the-art SCR technology. A further objective is to ready technology for full-scale commercial deployment to meet the market demand for NO{sub x} reduction technologies. Over half of the electric power generated in the U.S. is produced by coal combustion, and more than 80% of these units utilize PC combustion technology. Conventional measures for NOx reduction in PC combustion processes rely on combustion and post-combustion modifications. A variety of combustion-based NO{sub x} reduction technologies are in use today, including low-NO{sub x} burners (LNBs), flue gas recirculation (FGR), air staging, and natural gas or other fuel reburning. Selective non-catalytic reduction (SNCR) and selective catalytic reduction (SCR) are post-combustion techniques. NO{sub x} reduction effectiveness from these technologies ranges from 30 to 60% and up to 90-93% for SCR. Typically, older wall-fired PC burner units produce NO{sub x} emissions in the range of 0.8-1.6 lb/million Btu. Low-NO{sub x} burner systems, using combinations of fuel staging within the burner and air staging by introduction of overfire air in the boiler, can reduce NO{sub x} emissions by 50-60%. This approach alone is not sufficient to meet the desired 0.15 lb/million Btu NO{sub x} standard with a range of coals and boiler loads. Furthermore, the heavy reliance on overfire air can lead to increased slagging and corrosion in furnaces, particularly with higher-sulfur coals, when LNBs are operated at sub-stoichiometric conditions to reduce fuel-derived NOx in the flame. Therefore, it is desirable

    This paper proposes deterministic algorithms for decentralized network coding. Decentralized coding allows to locally specify the coding operations at network nodes without knowledge of the overall network topology, and to accommodate future changes in the network such as addition of receivers. To the best of our knowledge, these are the first deterministic decentralized algorithms proposed for network coding.

Cramer is thus the voice of a new ‘code...... discusses code as the artist’s material and, further, formulates a critique of Cramer.

    Donnell, B.

    1994-01-01

    COOL (that is, a rule can pattern match on objects created using COOL). CLIPS 6.0 provides the capability to define functions, overloaded functions, and global variables interactively. In addition, CLIPS can be embedded within procedural code, called as a subroutine, and integrated with languages such as C, FORTRAN and Ada. CLIPS can be easily extended by a user through the use of several well-defined protocols. CLIPS provides several delivery options for programs including the ability to generate stand alone executables or to load programs from text or binary files. CLIPS 6.0 provides support for the modular development and execution of knowledge bases with the defmodule construct. CLIPS modules allow a set of constructs to be grouped together such that explicit control can be maintained over restricting the access of the constructs by other modules. This type of control is similar to global and local scoping used in languages such as C or Ada. By restricting access to deftemplate and defclass constructs, modules can function as blackboards, permitting only certain facts and instances to be seen by other modules. Modules are also used by rules to provide execution control. The CRSV (Cross-Reference, Style, and Verification) utility included with previous version of CLIPS is no longer supported. The capabilities provided by this tool are now available directly within CLIPS 6.0 to aid in the development, debugging, and verification of large rule bases. COSMIC offers four distribution versions of CLIPS 6.0: UNIX (MSC-22433), VMS (MSC-22434), MACINTOSH (MSC-22429), and IBM PC (MSC-22430). Executable files, source code, utilities, documentation, and examples are included on the program media. All distribution versions include identical source code for the command line version of CLIPS 6.0. This source code should compile on any platform with an ANSI C compiler. Each distribution version of CLIPS 6.0, except that for the Macintosh platform, includes an executable for the

  3. Radioimmunoassay data processing program for IBM PC computers

    International Nuclear Information System (INIS)

    The Medical Applications Section of the International Atomic Energy Agency (IAEA) has previously developed several programs for use on the Hewlett-Packard HP-41C programmable calculator to facilitate better quality control in radioimmunoassay through improved data processing. The program described in this document is designed for off-line analysis using an IBM PC (or compatible) for counting data from standards and unknown specimens (i.e. for analysis of counting data previously recorded by a counter), together with internal quality control (IQC) data both within and between batch. The greater computing power of the IBM PC has enabled the imprecision profile and IQC control curves which were unavailable on the HP-41C version. It is intended that the program would make available good data processing capability to laboratories having limited financial resources and serious problems of quality control. 3 refs

    2016-01-01

    It was proposed that the narrow $P_c(4450)$ structure observed by the LHCb Collaboration in the reaction $\\Lambda_b\\to J/\\psi p K$ might be due to a triangle singularity around the $\\chi_{c1}$--proton threshold at 4.45~GeV. We discuss the occurrence of a similar triangle singularity in the $J/\\psi p$ invariant mass distribution for the decay $\\Lambda_b\\to J/\\psi p \\pi$, which could explain the bump around 4.45~GeV in the data. More precise measurements of this process would provide valuable information towards an understanding of the $P_c$ structures.

    International Nuclear Information System (INIS)

    The Spallation Neutron Source (SNS) project's diagnostics group has begun its implementation of more than 300 PC-based Network Attached Devices (NADs). An implementation of this size creates many challenges, such as distribution of patches and software upgrades; virus/worm potentials; and the configuration management, including interaction with the SNS relational database. As part of the initial solution, a base operating system (OS) configuration has been determined and computer management software has been implemented. Each PC requires a unique configuration, but all are based on a common OS and supporting applications. The diagnostics group has started with an implementation of an XP Embedded (XPe) OS and uses Altiris registered eXpress Deployment SolutionTM. The use of XPe and Altiris gives the diagnostics group the ability to easily configure, distribute, and manage software on a large scale. This paper describes the initial experience and discusses plans for the future

  8. Studies on molecular interactions between puerarin and PC liposomes

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Fluorescence emission spectra, FTIR spectra, zeta potential measurements, and ab initio quantum calculation are used to study the interaction between puerarin and membranes composed of egg phosphatidylcholine (PC) liposome. The hydrophobic interactions cause the puerarin molecule to partition into lipid bilayers with its B-ring, and favor the displacement of acid-base equilibrium of puerarin towards the base form. Due to the hydrogen bond formation between the puerarin hydroxyl groups and polar groups of PC molecules on the water/membrane interface, puerarin can easily intercalate into the organized structure of phospholipids and modulate the membrane function. Our results reveal that the liposome membrane integrity is significantly higher compared with that of empty liposome.

  11. PC analysis of stochastic differential equations driven by Wiener noise

    KAUST Repository

    Le Maître, Olivier Le

    2015-03-01

    A polynomial chaos (PC) analysis with stochastic expansion coefficients is proposed for stochastic differential equations driven by additive or multiplicative Wiener noise. It is shown that for this setting, a Galerkin formalism naturally leads to the definition of a hierarchy of stochastic differential equations governing the evolution of the PC modes. Under the mild assumption that the Wiener and uncertain parameters can be treated as independent random variables, it is also shown that the Galerkin formalism naturally separates parametric uncertainty and stochastic forcing dependences. This enables us to perform an orthogonal decomposition of the process variance, and consequently identify contributions arising from the uncertainty in parameters, the stochastic forcing, and a coupled term. Insight gained from this decomposition is illustrated in light of implementation to simplified linear and non-linear problems; the case of a stochastic bifurcation is also considered.

    Development of a responsive, high-bandwidth missile autopilot for airframes which have structural modes of unusually low frequency presents a challenging design task. Such systems are viable candidates for modern, state-space control design methods. The PC-MATLAB interactive software package provides an environment well-suited to the development of candidate linear control laws for flexible missile autopilots. The strengths of MATLAB include: (1) exceptionally high speed (MATLAB's version for 80386-based PC's offers benchmarks approaching minicomputer and mainframe performance); (2) ability to handle large design models of several hundred degrees of freedom, if necessary; and (3) broad extensibility through user-defined functions. To characterize MATLAB capabilities, a simplified design example is presented. This involves interactive definition of an observer-based state-space compensator for a flexible missile autopilot design task. MATLAB capabilities and limitations, in the context of this design task, are then summarized.

    PC12 cells habituate during repetitive stimulation with acetylcholine, bradykinin, or high potassium. Interspersing these stimulants did not affect the rate of habituation of the others, but it could modulate the amplitude of the norepinephrine secretion each could achieve. Stimulation with acetylcholine inhibited norepinephrine secretion caused by high potassium and bradykinin stimulation, while high potassium had no effect on acetylcholine or bradykinin, and bradykinin increased secretion c...

    I work in the Flight Software Engineering Branch, where we provide design and development of embedded real-time software applications for flight and supporting ground systems to support the NASA Aeronautics and Space Programs. In addition, this branch evaluates, develops and implements new technologies for embedded real-time systems, and maintains a laboratory for applications of embedded technology. The majority of microchips that are used in modern society have been programmed using embedded technology. These small chips can be found in microwaves, calculators, home security systems, cell phones and more. My assignment this summer entails working with an iPAQ HP 5500 Pocket PC. This top-of-the-line hand-held device is one of the first mobile PC's to introduce biometric security capabilities. Biometric security, in this case a fingerprint authentication system, is on the edge of technology as far as securing information. The benefits of fingerprint authentication are enormous. The most significant of them are that it is extremely difficult to reproduce someone else's fingerprint, and it is equally difficult to lose or forget your own fingerprint as opposed to a password or pin number. One of my goals for this summer is to integrate this technology with another Pocket PC application. The second task for the summer is to develop a simple application that provides an Astronaut EVA (Extravehicular Activity) Log Book capability. The Astronaut EVA Log Book is what an astronaut would use to report the status of field missions, crew physical health, successes, future plans, etc. My goal is to develop a user interface into which these data fields can be entered and stored. The applications that I am developing are created using eMbedded Visual C++ 4.0 with the Pocket PC 2003 Software Development Kit provided by Microsoft.

    The secretion of the hormone insulin from beta cells is modulated by the expression of the dense core vesicle transmembrane protein IA-2. Since IA-2 is found in neuroendocrine cells throughout the body, the present experiments were initiated to determine whether the expression of IA-2 also modulates the secretion of neurotransmitters. Using the dopamine-secreting pheochromocytoma cell line PC12, we found that the overexpressions of IA-2 increased the cellular content and secretion of dopamine...

    We estimate the kinematic dependence of the exclusive photo-- and electroproduction of $J^{PC}=1^{-+}$ exotic mesons due to $\\pi$ exchange. We show that the kinematic dependence is largely independent of the exotic meson form factor, which is explicitly derived for a $1^{-+}$ isovector hybrid meson in the flux-tube model of Isgur and Paton. The relevance to experiments currently planned at Jefferson Lab is indicated.

  10. LysoPC acyltransferase/PC transacylase activities in plant plasma membrane and plasma membrane-associated endoplasmic reticulum

    Directory of Open Access Journals (Sweden)

    Tjellström Henrik

    2007-11-01

    Full Text Available Abstract Background The phospholipids of the plant plasma membrane are synthesized in the endoplasmic reticulum (ER. The majority of these lipids reach the plasma membrane independently of the secretory vesicular pathway. Phospholipid delivery to the mitochondria and chloroplasts of plant cells also bypasses the secretory pathway and here it has been proposed that lysophospholipids are transported at contact sites between specific regions of the ER and the respective organelle, followed by lysophospholipid acylation in the target organelle. To test the hypothesis that a corresponding mechanism operates to transport phospholipids to the plasma membrane outside the secretory pathway, we investigated whether lysolipid acylation occurs also in the plant plasma membrane and whether this membrane, like the chloroplasts and mitochondria, is in close contact with the ER. Results The plant plasma membrane readily incorporated the acyl chain of acyl-CoA into phospholipids. Oleic acid was preferred over palmitic acid as substrate and acyl incorporation occurred predominantly into phosphatidylcholine (PC. Phospholipase A2 stimulated the reaction, as did exogenous lysoPC when administered in above critical micellar concentrations. AgNO3 was inhibitory. The lysophospholipid acylation reaction was higher in a membrane fraction that could be washed off the isolated plasma membranes after repeated freezing and thawing cycles in a medium with lowered pH. This fraction exhibited several ER-like characteristics. When plasma membranes isolated from transgenic Arabidopsis expressing green fluorescent protein in the ER lumen were observed by confocal microscopy, membranes of ER origin were associated with the isolated plasma membranes. Conclusion We conclude that a lysoPC acylation activity is associated with plant plasma membranes and cannot exclude a PC transacylase activity. It is highly plausible that the enzyme(s resides in a fraction of the ER, closely

    International Nuclear Information System (INIS)

    Electronic transitions at interfaces between MoO3 layers and organic layers of C60, SubPc, MgPc, and nano-composite layers of SubPc:C60 and MgPc:C60 have been studied by modulated surface photovoltage (SPV) spectroscopy. For all systems, time dependent and modulated SPV signals pointed to dissociation of excitons at the MoO3/organic layer interfaces with a separation of holes towards MoO3. The highest occupied molecular orbital (HOMO)-lowest unoccupied molecular orbital (LUMO) gaps (EHL) of C60, SubPc, and MgPc and the effective EHL of SubPc:C60 and MgPc:C60 were measured. The offsets between the LUMO (ΔEL) or HOMO (ΔEH) bands were obtained with high precision and amounted to 0.33 or 0.73 eV for SubPc:C60, respectively, and to −0.33 or 0.67 eV for MgPc:C60, respectively. Exponential tails below EHL and most pronounced sub-bandgap transitions were characterized and ascribed to disorder and transitions from HOMO bands to unoccupied defect states

    2007-02-01

    Digital light processing (DLP) is an innovative display technology that uses an optical switch array, known as a digital micromirror device (DMD), which allows digital control of light. To date, DMDs have been used primarily as high-speed spatial light modulators for projector applications. A tablet PC is a notebook or slate-shaped mobile PC. Its touch screen or digitizing tablet technology allows the user to operate the notebook with a stylus or digital pen instead of using a keyboard or mouse. In this paper, we describe an interface solution that translates any sketch on the tablet PC screen to an identical mirror-copy over the cross-section of the DMD micromirrors such that the image of the sketch can be projected onto a special screen. An algorithm has been created to control each single micromirror of the hundreds of thousands of micromirrors that cover the DMD surface. We demonstrate the successful application of a DMD to a high-speed two-dimensional (2D) scanning environment, acquiring the data from the tablet screen and launching its contents to the projection screen; with very high accuracy up to 13.68 μm x 13.68 μm of mirror pitch.

  14. The reactor physics computer programs in PC's era

    International Nuclear Information System (INIS)

    The main objective of reactor physics analysis is the evaluation of flux and power distribution over the reactor core. For CANDU reactors sophisticated computer programs, such as FMDP and RFSP, were developed 20 years ago for mainframe computers. These programs were adapted to work on workstations with UNIX or DOS, but they lack a feature that could improve their use and that is 'user friendly'. For using these programs the users need to deal with a great amount of information contained in sophisticated files. To modify a model is a great challenge. First of all, it is necessary to bear in mind all the geometrical dimensions and accordingly, to modify the core model to match the new requirements. All this must be done in a line input file. For a DOS platform, using an average performance PC system, could it be possible: to represent and modify all the geometrical and physical parameters in a meaningful way, on screen, using an intuitive graphic user interface; to reduce the real time elapsed in order to perform complex fuel-management analysis 'at home'; to avoid the rewrite of the mainframe version of the program? The author's answer is a fuel-management computer package operating on PC, 3 time faster than on a CDC-Cyber 830 mainframe one (486DX/33MHz/8MbRAM) or 20 time faster (Pentium-PC), respectively.

    Blends of PC and PPSQ (A) with high Mw and good ladderlike regularity or PPSQ(B) with low Mw and more defective Si-atoms in its structure have been prepared by solution casting. The dispersed spheres (PPSQ(A)-rich) are unevenly dispersed in the continuous PC-rich phase and there is no phase-inversion as PPSQ(A) content increases when the percentage of PPSQ(A) is not more than70%. PPSQ(B)-rich spheres are evenly dispersed in the continuous phase (PC-rich) and phaseinversion occurs when PPSQ(B) percentage is up to 70%. Tg of PPSQ(A)/PC or PPSQ(B)/PC at some compositions are lower than that of pure PC due to the enlarged free-volume of PC-rich phase because some spheres of rigid PPSQ chains are included in the PC-rich phase. PC and PPSQ(A) or PPSQ(B)are partially compatible. The compatibility of PC and PPSQ(B) is better than that of PC and PPSQ(A)with high Mw and good ladderlike regularity. Heat history has some influence on the TgS and compatibility of PPSQ(A)/PC and PPSQ(B)/PC blends.

    This study aims to design and generate recombinant lentiviral vector containing the complete coding sequence (CDS) region of human serine protease inhibitor Kazal type 1 gene (SPINK1) and establish a human pancreatic cancer cell line (AsPC-1) stably overexpressing SPINK1. Then, to assess the proliferative and oncogenic effects of upregulated SPINK1 gene on pancreatic cancer AsPC-1 cells using different methods. Initially, the target coding sequence (CDS) of SPINK1 was amplified by polymerase chain reaction (PCR) and the synthesized product was subsequently subcloned into the lentiviral vector. The construction of recombinant SPINK1 gene was verified by the restriction digestion and sequencing analysis. The lentiviral particles carrying SPINK1 gene were produced by co-transfection of the recombination lentiviral vector and the packaging mix plasmids into 293 T cells and filtered and concentrated before AsPC-1 cells were infected by the virus particles. The cells transduced were differentially selected with puromycin, and the clones that highly expressed SPINK1 were chosen by real-time PCR and confirmed by Western blot after 7 weeks. The stably transduced AsPC-1 cell line showed significantly increased metabolic and proliferative capability using CCK-8 and Trypan Blue assays (P < 0.001). Cell cycle and DNA content analysis by flow cytometry showed that upregulated SPINK1 elicited significant increase in the percentage of AsPC-1 cells in the S and G2/M phase (P < 0.001). Clone formation assay demonstrated that the number of the colonies formed in the experimental group was greater than that in the control parental cells (P < 0.001). It was concluded that a stable AsPC-1 cell line capable of overexpressing SPINK1 had been successfully created, and that the proliferative capacity of AsPC-1 pancreatic cancer cells was significantly raised by SPINK1 upregulation as well as the ability of a single AsPC-1 cell to grow into a colony.

    Just like PTM or PTLM (post-translational modification) in proteins, PTCM (post-transcriptional modification) in RNA plays very important roles in biological processes. Occurring at adenine (A) with the genetic code motif (GAC), N(6)-methyldenosine (m(6)A) is one of the most common and abundant PTCMs in RNA found in viruses and most eukaryotes. Given an uncharacterized RNA sequence containing many GAC motifs, which of them can be methylated, and which cannot? It is important for both basic research and drug development to address this problem. Particularly with the avalanche of RNA sequences generated in the postgenomic age, it is highly demanded to develop computational methods for timely identifying the N(6)-methyldenosine sites in RNA. Here we propose a new predictor called pRNAm-PC, in which RNA sequence samples are expressed by a novel mode of pseudo dinucleotide composition (PseDNC) whose components were derived from a physical-chemical matrix via a series of auto-covariance and cross covariance transformations. It was observed via a rigorous jackknife test that, in comparison with the existing predictor for the same purpose, pRNAm-PC achieved remarkably higher success rates in both overall accuracy and stability, indicating that the new predictor will become a useful high-throughput tool for identifying methylation sites in RNA, and that the novel approach can also be used to study many other RNA-related problems and conduct genome analysis. A user-friendly Web server for pRNAm-PC has been established at http://www.jci-bioinfo.cn/pRNAm-PC, by which users can easily get their desired results without needing to go through the mathematical details.

    We use a combination of molecular dynamics simulations and density functional theory calculations to investigate the energetic disorder in fullerene systems. We show that the energetic disorder evaluated from an ensemble average contains contributions of both static origin (time-independent, due to loose packing) and dynamic origin (time-dependent, due to electron-vibration interactions). In order to differentiate between these two contributions, we compare the results obtained from an ensemble average approach with those derived from a time average approach. It is found that in both amorphous C60 and C70 bulk systems, the degrees of static and dynamic disorder are comparable, while in the amorphous PC61BM and PC71BM systems, static disorder is about twice as large as dynamic disorder.

    Highlights: • We determine the optical properties of two fullerene derivatives using ellipsometry. • Multisample analysis is applied to verify the uniqueness of the model. • The energy position of the oscillators used are compared with ones present in the parent molecules. - Abstract: Spectroscopic ellipsometry is used to determine the optical properties and to extract electronic transitions of PC{sub 60}BM and PC{sub 70}BM thin films in the UV–Visible range. By means of a sum of Gaussian oscillators, the imaginary parts of dielectric functions of both materials are modeled. The physical meaning of each model is checked by comparing the energy position of the oscillators with known optical transitions of the C{sub 60} and C{sub 70} molecules as revealed in literature by others techniques. It is shown that spectroscopic ellipsometry is a powerful technique to investigate the electronic structure of pi-conjugated molecules.

    We study the strong decay channels Pc+(4380 )→J /ψ p and Pc+(4450 )→J /ψ p under a ΣcD¯* molecular state ansatz. With various spin-parity assignments, the partial decay widths of the J /ψ p final state are calculated. Our results show that all the P wave ΣcD¯* assignments are excluded, while S wave ΣcD¯* pictures for Pc(4380 ) and Pc(4450 ) are both allowed by present experimental data. The JP=3 /2- Σc*D ¯ and Σc*D¯* molecules are also discussed in the heavy quark limit, and we find that the Σc*D ¯ system for Pc(4380 ) is possible. More experimental information on spin parities and partial decay widths and theoretical investigations on other decay modes are needed to clarify the nature of the two Pc states.

  5. A PC-based data acquisition system for enhanced reactor operation

    International Nuclear Information System (INIS)

    A PC-based data acquisition system, developed at the PUSPATI TRIGA Reactor facility (RTP), has proven to be a versatile tool in improving both operational and research capabilities. The system consists of a 16-bit personal computer with plug-in input/output board that captures analog signals and converts them to digital form with 12-bit accuracy. Direct memory access within the board enables fast communication through the host PC buslines. Built-in micro-coded commands were combined with the BASIC-language software. At the signal end, isolation amplifiers were installed for protection against ground disturbances and loops. Applications of the system include computerized rod and power calibrations. Menu-driven software and computerized data logging has increased accuracy at minimal manpower costs. For reactor operation monitoring, up to 16 single-ended input channels were available with a maximum sampling capability of 13,700 samples per second. Analog signals such as reactor power, fuel temperature and control rod positions were tapped from the instrumentation channels and sequentially multiplexed and digitized, then displayed on a monitor which serves as additional operator support. Data continuously monitored can be easily stored and retrieved, enabling rapid access and efficient management. The data acquisition system has also been used for work on reactor noise analysis. Signals from the fission chamber of the linear power channel were sampled in various operating modes at different power levels to identify noise signatures and sources. Software development centered on frequency and time domain analysis, file management and plotting routines. The initial language used was FORTRAN 1.0 but this was rewritten in PASCAL 2.0 to enhance calculation speed and reduce storage space. Results show that the technique was capable of detecting core disturbances caused by control rod oscillation and uneven distribution of samples in the specimen rotary rack during operation

    Elsenhans, Andreas-Stephan; Wassermann, Alfred

    2010-01-01

    Based on ideas of K\\"otter and Kschischang we use constant dimension subspaces as codewords in a network. We show a connection to the theory of q-analogues of a combinatorial designs, which has been studied in Braun, Kerber and Laue as a purely combinatorial object. For the construction of network codes we successfully modified methods (construction with prescribed automorphisms) originally developed for the q-analogues of a combinatorial designs. We then give a special case of that method which allows the construction of network codes with a very large ambient space and we also show how to decode such codes with a very small number of operations.

    International Nuclear Information System (INIS)

    In the framework of the contractual agreement between the Ministry of Energy and Infrastructure and the Division of Nuclear Engineering of the Israel Atomic Energy Commission, both Soreq-NRC and Ben-Gurion University have agreed to establish, in 1991, a code center. This code center contains a library of computer codes and relevant data, with particular emphasis on nuclear power plant research and development support. The code center maintains existing computer codes and adapts them to the ever changing computing environment, keeps track of new code developments in the field of nuclear engineering, and acquires the most recent revisions of computer codes of interest. An attempt is made to collect relevant codes developed in Israel and to assure that proper documentation and application instructions are available. En addition to computer programs, the code center collects sample problems and international benchmarks to verify the codes and their applications to various areas of interest to nuclear power plant engineering and safety evaluation. Recently, the reactor simulation group at Soreq acquired, using funds provided by the Ministry of Energy and Infrastructure, a PC work station operating under a Linux operating system to give users of the library an easy on-line way to access resources available at the library. These resources include the computer codes and their documentation, reports published by the reactor simulation group, and other information databases available at Soreq. Registered users set a communication line, through a modem, between their computer and the new workstation at Soreq and use it to download codes and/or information or to solve their problems, using codes from the library, on the computer at Soreq (authors)

    Mi, Ye; Tower, Leonard K.

    2013-01-01

    NASA Glenn Research Center (GRC) has developed the LERCHP code. The PC-based LERCHP code can be used to predict the steady-state performance of heat pipes, including the determination of operating temperature and operating limits which might be encountered under specified conditions. The code contains a vapor flow algorithm which incorporates vapor compressibility and axially varying heat input. For the liquid flow in the wick, Darcy s formula is employed. Thermal boundary conditions and geometric structures can be defined through an interactive input interface. A variety of fluid and material options as well as user defined options can be chosen for the working fluid, wick, and pipe materials. This report documents the current effort at GRC to update the LERCHP code for operating in a Microsoft Windows (Microsoft Corporation) environment. A detailed analysis of the model is presented. The programming architecture for the numerical calculations is explained and flowcharts of the key subroutines are given

  16. A description of the ENIGMA fuel performance code

    International Nuclear Information System (INIS)

    An overview of the main features and characteristics of the ENIGMA code developed by BNFL and CEGB is given. A general description as well as some specific sub-models are presented. One of the characteristics of this code is its fully-modular conception. Each submodel treats a well identified basic mechanism. This detailed, semi-empirical formulation of physical models contributes to reducing the number of tuning parameters. The advantage of such a modular construction is the easy replacement of a model if a less empirical one becomes available, or if shortcomings in current models are discovered. The code can be run on a PC equipped with a transputer. An extensive programme of code assessment is currently underway. (author). 9 refs, 9 figs, 1 tab

    The topological color code and the toric code are two leading candidates for realizing fault-tolerant quantum computation. Here we show that the color code on a $d$-dimensional closed manifold is equivalent to multiple decoupled copies of the $d$-dimensional toric code up to local unitary transformations and adding or removing ancilla qubits. Our result not only generalizes the proven equivalence for $d=2$, but also provides an explicit recipe of how to decouple independent components of the ...

  18. FLUID- THERMODYNAMIC AND TRANSPORT PROPERTIES OF FLUIDS (IBM PC VERSION)

    Science.gov (United States)

    Fessler, T. E.

    1994-01-01

    The accurate computation of the thermodynamic and transport properties of fluids is a necessity for many engineering calculations. The FLUID program was developed to calculate the thermodynamic and transport properties of pure fluids in both the liquid and gas phases. Fluid properties are calculated using a simple gas model, empirical corrections, and an efficient numerical interpolation scheme. FLUID produces results that are in very good agreement with measured values, while being much faster than older more complex programs developed for the same purpose. A Van der Waals equation of state model is used to obtain approximate state values. These values are corrected for real-gas effects by model correction factors obtained from tables based on experimental data. These tables also accurately compensate for the special circumstances which arise whenever phase conditions occur. Viscosity and thermal conductivity values are computed directly from tables. Interpolation within tables is based on Lagrange's three point formula. A set of tables must be generated for each fluid implemented. FLUID currently contains tables for nine fluids including dry air and steam. The user can add tables for any fluid for which adequate thermal property data is available. The FLUID routine is structured so that it may easily be incorporated into engineering programs. The IBM 360 version of FLUID was developed in 1977. It is written in FORTRAN IV and has been implemented on an IBM 360 with a central memory requirement of approximately 222K of 8 bit bytes. The IBM PC version of FLUID is written in Microsoft FORTRAN 77 and has been implemented on an IBM PC with a memory requirement of 128K of 8 bit bytes. The IBM PC version of FLUID was developed in 1986.

  14. Comparison of CAP88 PC Ver. 3.0 and MAXDOSE dose assessment models involving co-located stack releases at the Savannah River site.

    Science.gov (United States)

    Farfán, Eduardo; Jannik, G Timothy; Lee, Patricia; Powell, Aaron

    2013-08-01

    The Savannah River National Laboratory's Environmental Dosimetry Group performs dosimetry assessments for Savannah River Site (SRS) radionuclide air emissions utilizing the Clean Air Act Assessment Package-1988 (CAP88) code (CAP88 PC Ver. 3.0) and the MAXDOSE-SR Ver. 2011 code, which is an SRS-specific version of the Nuclear Regulatory Commission's MAXIGASP code. CAP88 PC and MAXDOSE-SR are used at SRS for demonstrating compliance with Environmental Protection Agency dose standards for radionuclide emissions to the atmosphere and Department of Energy Order 458.1 dose standards, respectively. During a routine comparison of these two assessment models, it was discovered that CAP88 PC Ver. 3.0 was not producing the expected results when using multiple co-located stacks in a single run. Specifically, if the stack heights are considered separately, the results for several radionuclides (but not all) differ from the combined run [i.e., 1 + 2 does not equal (1+2)]. Additionally, when two or more stack heights are considered in a run, the results depend on the order of the selected stack heights. For example, for a two stack-height run of 0 meter and 61 m input produces different results from a 61 m and 0 m input run. This study presents a comparison of CAP88 PC Ver. 3.0 and MAXDOSE-SR Ver. 2011 based on SRS input data and on two-stack release scenarios. The selected radionuclides for this study included gases/vapors (H, C, Kr, and I) and particulates (Sr, Cs, Pu, and Am) commonly encountered at SRS. PMID:23803669

  15. PrPC displays an essential protective role from oxidative stress in an astrocyte cell line derived from PrPC knockout mice

    International Nuclear Information System (INIS)

    Highlights: ► PrPC in solution acts as a radical scavenger. ► PrPC reduces hydrogen peroxide toxicity in astrocytes. ► Increase in ROS disrupted the cell cycle in the PrPC-knockout astrocytes. ► PrPC prevents the cell death independently of an SOD-like activity. -- Abstract: The PrPC protein, which is especially present in the cellular membrane of nervous system cells, has been extensively studied for its controversial antioxidant activity. In this study, we elucidated the free radical scavenger activity of purified murine PrPC in solution and its participation as a cell protector in astrocytes that were subjected to treatment with an oxidant. In vitro and using an EPR spin-trapping technique, we observed that PrPC decreased the oxidation of the DMPO trap in a Fenton reaction system (Cu2+/ascorbate/H2O2), which was demonstrated by approximately 70% less DMPO/OH·. In cultured PrPC-knockout astrocytes from mice, the absence of PrPC caused an increase in intracellular ROS (reactive oxygen species) generation during the first 3 h of H2O2 treatment. This rapid increase in ROS disrupted the cell cycle in the PrPC-knockout astrocytes, which increased the population of cells in the sub-G1 phase when compared with cultured wild-type astrocytes. We conclude that PrPC in solution acts as a radical scavenger, and in astrocytes, it is essential for protection from oxidative stress caused by an external chemical agent, which is a likely condition in human neurodegenerative CNS disorders and pathological conditions such as ischemia.

    International Nuclear Information System (INIS)

    This report is a detailed description on the TPC code, that calculates the power balance of a tokamak plasma according to the ITER guidelines. The TPC code works on a personal computer (Macintosh or J-3100/ IBM-PC). Using input data such as the plasma shape, toroidal magnetic field, plasma current, electron temperature, electron density, impurities and heating power, TPC code can determine the operation point of the fusion reactor (Ion temperature is assumed to be equal to the electron temperature). Supplied flux (Volt · sec) and burn time are also estimated by coil design parameters. Calculated energy confinement time is compared with various L-mode scaling laws and the confinement enhancement factor (H-factor) is evaluated. Divertor heat load is predicted by using simple scaling models (constant-χ, Bohm-type-χ and JT-60U empirical scaling models). Frequently used data can be stored in a 'device file' and used as the default values. TPC code can generate 2-D mesh data and the POPCON plot is drawn by a contour line plotting program (CONPLT). The operation manual about CONPLT code is also described. (author)

A 171-group problem-oriented data library is usually used in 1 dimensional calculations by the code ANISN. This library is being generated by the AMPX modules (BONAMI and others). Data libraries with smaller number of groups are being used in 2 dimensional calculations by DOT-3. These libraries have been gotten from 171-group problem-oriented libraries which are averaged by corresponding spectra from 1 dimensional calculations. Using of the described system is being demonstrated with two examples. (authors). 6 refs., 2 tabs., 5 figs

  1. Universal Rateless Codes From Coupled LT Codes

    CERN Document Server

    Aref, Vahid

    2011-01-01

    It was recently shown that spatial coupling of individual low-density parity-check codes improves the belief-propagation threshold of the coupled ensemble essentially to the maximum a posteriori threshold of the underlying ensemble. We study the performance of spatially coupled low-density generator-matrix ensembles when used for transmission over binary-input memoryless output-symmetric channels. We show by means of density evolution that the threshold saturation phenomenon also takes place in this setting. Our motivation for studying low-density generator-matrix codes is that they can easily be converted into rateless codes. Although there are already several classes of excellent rateless codes known to date, rateless codes constructed via spatial coupling might offer some additional advantages. In particular, by the very nature of the threshold phenomenon one expects that codes constructed on this principle can be made to be universal, i.e., a single construction can uniformly approach capacity over the cl...

  5. Nasal associated lymphoid tissue of the Syrian golden hamster expresses high levels of PrPC.

    Directory of Open Access Journals (Sweden)

    Melissa D Clouse

    Full Text Available The key event in the pathogenesis of the transmissible spongiform encephalopathies is a template-dependent misfolding event where an infectious isoform of the prion protein (PrPSc comes into contact with native prion protein (PrPC and changes its conformation to PrPSc. In many extraneurally inoculated models of prion disease this PrPC misfolding event occurs in lymphoid tissues prior to neuroinvasion. The primary objective of this study was to compare levels of total PrPC in hamster lymphoid tissues involved in the early pathogenesis of prion disease. Lymphoid tissues were collected from golden Syrian hamsters and Western blot analysis was performed to quantify PrPC levels. PrPC immunohistochemistry (IHC of paraffin embedded tissue sections was performed to identify PrPC distribution in tissues of the lymphoreticular system. Nasal associated lymphoid tissue contained the highest amount of total PrPC followed by Peyer's patches, mesenteric and submandibular lymph nodes, and spleen. The relative levels of PrPC expression in IHC processed tissue correlated strongly with the Western blot data, with high levels of PrPC corresponding with a higher percentage of PrPC positive B cell follicles. High levels of PrPC in lymphoid tissues closely associated with the nasal cavity could contribute to the relative increased efficiency of the nasal route of entry of prions, compared to other routes of infection.

    International Nuclear Information System (INIS)

    This report describes the source term estimation codes, XSORs. The codes are written for three pressurized water reactors (Surry, Sequoyah, and Zion) and two boiling water reactors (Peach Bottom and Grand Gulf). The ensemble of codes has been named ''XSOR''. The purpose of XSOR codes is to estimate the source terms which would be released to the atmosphere in severe accidents. A source term includes the release fractions of several radionuclide groups, the timing and duration of releases, the rates of energy release, and the elevation of releases. The codes have been developed by Sandia National Laboratories for the US Nuclear Regulatory Commission (NRC) in support of the NUREG-1150 program. The XSOR codes are fast running parametric codes and are used as surrogates for detailed mechanistic codes. The XSOR codes also provide the capability to explore the phenomena and their uncertainty which are not currently modeled by the mechanistic codes. The uncertainty distributions of input parameters may be used by an. XSOR code to estimate the uncertainty of source terms

    This reference manual provides users of the NAGRADATA system with comprehensive keys to the coding/decoding of geological and technical information to be stored in or retreaved from the databank. Emphasis has been placed on input data coding. When data is retreaved the translation into plain language of stored coded information is done automatically by computer. Three keys each, list the complete set of currently defined codes for the NAGRADATA system, namely codes with appropriate definitions, arranged: 1. according to subject matter (thematically) 2. the codes listed alphabetically and 3. the definitions listed alphabetically. Additional explanation is provided for the proper application of the codes and the logic behind the creation of new codes to be used within the NAGRADATA system. NAGRADATA makes use of codes instead of plain language for data storage; this offers the following advantages: speed of data processing, mainly data retrieval, economies of storage memory requirements, the standardisation of terminology. The nature of this thesaurian type 'key to codes' makes it impossible to either establish a final form or to cover the entire spectrum of requirements. Therefore, this first issue of codes to NAGRADATA must be considered to represent the current state of progress of a living system and future editions will be issued in a loose leave ringbook system which can be updated by an organised (updating) service.

  8. Computer codes for level 1 probabilistic safety assessment

    International Nuclear Information System (INIS)

    Probabilistic Safety Assessment (PSA) entails several laborious tasks suitable for computer codes assistance. This guide identifies these tasks, presents guidelines for selecting and utilizing computer codes in the conduct of the PSA tasks and for the use of PSA results in safety management and provides information on available codes suggested or applied in performing PSA in nuclear power plants. The guidance is intended for use by nuclear power plant system engineers, safety and operating personnel, and regulators. Large efforts are made today to provide PC-based software systems and PSA processed information in a way to enable their use as a safety management tool by the nuclear power plant overall management. Guidelines on the characteristics of software needed for management to prepare a software that meets their specific needs are also provided. Most of these computer codes are also applicable for PSA of other industrial facilities. The scope of this document is limited to computer codes used for the treatment of internal events. It does not address other codes available mainly for the analysis of external events (e.g. seismic analysis) flood and fire analysis. Codes discussed in the document are those used for probabilistic rather than for phenomenological modelling. It should be also appreciated that these guidelines are not intended to lead the user to selection of one specific code. They provide simply criteria for the selection. Refs and tabs

  9. Permutation codes for sources.

    1972-01-01

    Source encoding techniques based on permutation codes are investigated. For a broad class of distortion measures it is shown that optimum encoding of a source permutation code is easy to instrument even for very long block lengths. Also, the nonparametric nature of permutation encoding is well suited to situations involving unknown source statistics. For the squared-error distortion measure a procedure for generating good permutation codes of a given rate and block length is described. The performance of such codes for a memoryless Gaussian source is compared both with the rate-distortion function bound and with the performance of various quantization schemes. The comparison reveals that permutation codes are asymptotically ideal for small rates and perform as well as the best entropy-coded quantizers presently known for intermediate rates. They can be made to compare favorably at high rates, too, provided the coding delay associated with extremely long block lengths is tolerable.

  10. Testing algebraic geometric codes

    Institute of Scientific and Technical Information of China (English)

    2009-01-01

    Property testing was initially studied from various motivations in 1990’s. A code C  GF (r)n is locally testable if there is a randomized algorithm which can distinguish with high possibility the codewords from a vector essentially far from the code by only accessing a very small (typically constant) number of the vector’s coordinates. The problem of testing codes was firstly studied by Blum, Luby and Rubinfeld and closely related to probabilistically checkable proofs (PCPs). How to characterize locally testable codes is a complex and challenge problem. The local tests have been studied for Reed-Solomon (RS), Reed-Muller (RM), cyclic, dual of BCH and the trace subcode of algebraicgeometric codes. In this paper we give testers for algebraic geometric codes with linear parameters (as functions of dimensions). We also give a moderate condition under which the family of algebraic geometric codes cannot be locally testable.

  14. Pc based RF control system for the Vincy cyclotron

    International Nuclear Information System (INIS)

    The concept and design procedure for the RF control system of the VINCY cyclotron are described. Special attention has been paid to the choice of computer support of this system. The merits and limitations of the chosen solution have been analyzed. A PC type computer has been selected as the platform for performing the functions of initiation, control, and supervision of the RF system. The integration of the hardware is carried out by direct connection to the PC bus via standard communication interfaces. The system software operates under a graphic oriented Windows operating system applying the modern concept of virtual instrumentation. The application of this concept allowed considerable simplification of the operator-RF system interaction and resulted in additional flexibility of the software to further extensions or modifications of the system. The selected open architecture of the computer platform allows a simple and economic upgrading of the realized system in accordance with future requirements. Tests of the realized RF control system prototype are in progress. (authors)

  15. Compressional Pc 4 pulsations observed at synchronous orbit

    Science.gov (United States)

    Tonegawa, Y.

    1982-09-01

    The ATS-6 geosynchronous satellite's magnetometer data are examined in order to ascertain the behavior of Pc 4-type ULF wave magnetic oscillations in the 40-180 sec period range, for the June 1-August 31, 1974, interval. Two wave types are noted: the meridionally polarized, or 'compressional', and the azimuthally polarized, or 'transverse'; the latter occurring in the early morning hours, while the former occur in the afternoon. Eigenmode period calculations employing the GEOS 2 satellite's plasma density data indicate that the period of compressional waves, in the 40-110 sec range, agrees with the calculated period of the second haramonic oscillation of the magnetic field line passing through the satellite. Attention is given to a bounce resonant condition between azimuthally propagating waves and ring current protons, and the satisfaction of the resonant condition when the azimuthal angular wave number is longer than about 100 is seen as suggesting that the compressional Pc 4 waves cannot be observed on the ground, due to the ionospheric screening effect.

  16. PC analysis of stochastic differential equations driven by Wiener noise

    International Nuclear Information System (INIS)

    A polynomial chaos (PC) analysis with stochastic expansion coefficients is proposed for stochastic differential equations driven by additive or multiplicative Wiener noise. It is shown that for this setting, a Galerkin formalism naturally leads to the definition of a hierarchy of stochastic differential equations governing the evolution of the PC modes. Under the mild assumption that the Wiener and uncertain parameters can be treated as independent random variables, it is also shown that the Galerkin formalism naturally separates parametric uncertainty and stochastic forcing dependences. This enables us to perform an orthogonal decomposition of the process variance, and consequently identify contributions arising from the uncertainty in parameters, the stochastic forcing, and a coupled term. Insight gained from this decomposition is illustrated in light of implementation to simplified linear and non-linear problems; the case of a stochastic bifurcation is also considered. - Highlights: • Develop Galerkin formalism to propagate parametric uncertainty in stochastic models. • Decompose variance into orthogonal noise, parameter and mixed contributions. • Demonstrate spectral algorithms for uncertain linear system and a bifurcation model

  18. Various Schemes to Speed up the PC during Virus Scan

    Neha Bishnoi,

    2011-07-01

    Full Text Available The current threat landscape is changing and we have seen a large volume of new viruses captured by security vendors each day. Customers always complain that anti-virus software slow down their computers by consuming much of PC memory and resources. Antivirus developers have to keep on inserting new virus signatures into their databases as variety of zero-day threats over the internet are becoming more popular. Due to this large database anti-virus soft ware slows down the PC. However, the increasing size of the signaturefile is not the only reason to drag computers to a crawl during the virus scan. Many antivirus products are available in the market claiming for the safest and more efficient antivirus. In this paper we will also focus on the other reasons which contribute in slowing down the computer system during virus scan. Distributed antivirusscheme becomes a popular solution for this problem. In this paper we will discuss the distributed security infrastructure for deploying a light-weight and fast anti-virus product and will also elaborate the different schemes responsible for slowing down the computer systems and suggested solutions for the same. We have also discussed some problems related to Cloud Computing and some solutions to it in this paper.

  19. Regulation of CREB by moderate hypoxia in PC12 cells.

    2000-01-01

    The mechanisms by which excitable cells adapt and respond to changes in O2 levels remain largely unknown. We have investigated the effect of hypoxia on the cyclic AMP response element binding protein (CREB) transcription factor. PC12 cells were exposed to moderate levels of hypoxia (5% O2) for various times between 20 min and 6 hr. We found that hypoxia rapidly and persistently induced ser133 phosphorylation of CREB. This effect was more robust than that produced by exposing PC12 cells to either forskolin, KCl, or NGF. This effect was not due to activation of any of the previously known CREB kinases, including PKA, CaMK, PKC, p70s6k, or MAPKAP kinase-2. Thus, hypoxia may induce activation of a novel CREB kinase. To test whether phosphorylation of CREB was associated with an activation of CRE-dependent gene expression, cells were transfected with wild type and mutated regions of the 5'-flanking region of the tyrosine hydroxylase (TH) gene fused to a CAT reporter gene. Mutation of the CRE element in a TH reporter gene reduced, but did not abolish, the effects of hypoxia on TH gene expression. However, hypoxia did not induce transactivation of a GAL4-luciferase reporter by a GAL4-CREB fusion protein. Thus, the mechanism by which hypoxia regulates CREB is distinct, and more complex, than that induced by forskolin, depolarization, or nerve growth factor. PMID:10849656

  5. Longitudinal frequency variation of long-lasting EMIC Pc1-Pc2 waves localized in the inner magnetosphere

    Long-lasting (> 20 h) electromagnetic ion cyclotron (EMIC) Pc1-Pc2 waves were observed by the Athabasca (L =˜ 4.6) induction magnetometer and Canadian Array for Realtime Investigations of Magnetic Activity (L =˜ 4-6) fluxgate magnetometers on 5 April 2007. These waves showed a systematic frequency change with local time, the minimum frequency near dusk, and the maximum frequency near dawn. Assuming the plasmapause as a potential source region of the waves, we estimated the plasmapause location from localized proton enhancement (LPE) events observed at NOAA-Polar Orbiting Environmental Satellites and METOP-2 satellites. We found that the longitudinal frequency variation of EMIC waves has a clear correlation with the estimated plasmapause location and that the waves are in the frequency band between the equatorial helium and oxygen gyrofrequencies at the estimated plasmapause. With our analysis results we suggest that the LPE events are caused by wave-particle interaction with the helium band EMIC waves generated near the plasmapause.

    2010-02-01

    Objective: In in vitro photodynamic therapy, the LD50 of Pc 181 has been reported to be 7 to 8 times less than that of silicon phthalocyanine 4 (Pc 4). The Optical Pharmacokinetic System (OPS) can measure photosensitizer concentrations in accessible tissues non-invasively. We used OPS to evaluate the tumor pharmacokinetics of Pc 181 and Pc 4 and the tissue drug distribution in SCID mice bearing either human breast cancer MDA-MB-231 or human head and neck squamous cell carcinoma SCC-15 xenografts. Methods: Following iv administration of 2.5 mg/kg Pc 181 or 2 mg/kg Pc 4 to SCID mice, OPS measurements were taken on tumor and normal tissues between 5 and 4320 min in vivo or in situ. Results: Large variations in tumor Pc 181 concentrations were observed among mice. In MDA-MB-231 tumors, the Pc 181 concentration peaked at 240 min, and was retained in the tumor. Tumor Pc 181 concentrations were much less than the tumor Pc 4 concentrations at an equimolar dose. Pc 181 concentrations were the highest in liver, followed by spleen, and kidney. In mice bearing SCC-15 xenografts, skin and underlying tissue Pc 181 concentrations were higher than tumor concentrations at all time points examined. Conclusions: This first Pc 181 pharmacokinetics study described a tissue Pc 181 distribution similar to that of Pc 4. However, tumor Pc 181 concentrations were lower than those of Pc 4 at equimolar doses.

    To support the discussion on aeroelastic codes, a description of the code FLEXLAST was given and experiences within benchmarks and measurement programmes were summarized. The code FLEXLAST has been developed since 1982 at Stork Product Engineering (SPE). Since 1992 FLEXLAST has been used by Dutch industries for wind turbine and rotor design. Based on the comparison with measurements, it can be concluded that the main shortcomings of wind turbine modelling lie in the field of aerodynamics, wind field and wake modelling. (au)

  17. Phonological coding during reading.

    2014-11-01

    The exact role that phonological coding (the recoding of written, orthographic information into a sound based code) plays during silent reading has been extensively studied for more than a century. Despite the large body of research surrounding the topic, varying theories as to the time course and function of this recoding still exist. The present review synthesizes this body of research, addressing the topics of time course and function in tandem. The varying theories surrounding the function of phonological coding (e.g., that phonological codes aid lexical access, that phonological codes aid comprehension and bolster short-term memory, or that phonological codes are largely epiphenomenal in skilled readers) are first outlined, and the time courses that each maps onto (e.g., that phonological codes come online early [prelexical] or that phonological codes come online late [postlexical]) are discussed. Next the research relevant to each of these proposed functions is reviewed, discussing the varying methodologies that have been used to investigate phonological coding (e.g., response time methods, reading while eye-tracking or recording EEG and MEG, concurrent articulation) and highlighting the advantages and limitations of each with respect to the study of phonological coding. In response to the view that phonological coding is largely epiphenomenal in skilled readers, research on the use of phonological codes in prelingually, profoundly deaf readers is reviewed. Finally, implications for current models of word identification (activation-verification model, Van Orden, 1987; dual-route model, e.g., M. Coltheart, Rastle, Perry, Langdon, & Ziegler, 2001; parallel distributed processing model, Seidenberg & McClelland, 1989) are discussed. PMID:25150679

    Distributed storage systems for large-scale applications typically use replication for reliability. Recently, erasure codes were used to reduce the large storage overhead, while increasing data reliability. A main limitation of off-the-shelf erasure codes is their high-repair cost during single node failure events. A major open problem in this area has been the design of codes that {\\it i)} are repair efficient and {\\it ii)} achieve arbitrarily high data rates. In this paper, we explore the r...

    Joseph Rabovitser

    2000-07-05

    The overall project objective is the development and validation of an innovative combustion system, based on a novel coal preheating concept prior to combustion, that can reduce NO{sub x} emissions to 0.15 lb/million Btu or less on utility pulverized coal (PC) boilers. This NO{sub x} reduction should be achieved without loss of boiler efficiency or operating stability, and at more than 25% lower levelized cost than state-of-the-art SCR technology. A further objective is to make this technology ready for full-scale commercial deployment by 2002-2003 in order to meet an anticipated market demand for NO{sub x} reduction technologies resulting from the EPA's NO{sub x} SIP call.

  1. A materials accounting system for an IBM PC

    International Nuclear Information System (INIS)

    The authors have adapted the Los Alamos MASS accounting system for use on an IBM PC/AT at the Fuels Manufacturing Facility (FMF) at Argonne National Laboratory West (ANL-WEST). Cost of hardware and proprietary software was less than $10,000 per station. The system consists of three stations between which accounting information is transferred using floppy disks accompanying special nuclear material shipments. The programs were implemented in dBASEIII and were compiled using the proprietary software CLIPPER. Modifications to the inventory can be posted in just a few minutes, and operator/computer interaction is nearly instantaneous. After the records are built by the user, it takes 4-5 seconds to post the results to the database files. A version of this system was specially adapted and is currently in use at the FMF facility at Argonne National Laboratory. Initial satisfaction is adequate and software and hardware problems are minimal

    The optimization of injection molding process for polycarbonate/acrylonitrile-butadiene-styrene (PC/ABS) blends is studied using Taguchi method and principal component analysis (PCA). Four controllable process factors are studied at three levels each in the manufacturing process. The L9 orthogonal array is conducted to determine the optimum process factor/level combination for single quality of mechanical properties. In addition, the principal component analysis is employed to transform the correlated mechanical properties to a set of uncorrelated components and to evaluate a comprehensive index for multi-response cases. Then the optimum process factor/level combination for multiple qualities can be determined. Finally, the analysis of variance is used to find out the most influential injection molding parameter for single and multiple qualities problems.

  3. Page: a program for gamma spectra analysis in PC microcomputers

    International Nuclear Information System (INIS)

    PAGE is a software package, written in BASIC language, to perform gamma spectra analysis. It was developed to be used in a high-purity intrinsic germanium detector-multichannel analyser-PC microcomputer system. The analysis program of PAGE package accomplishes functions as follows: peak location; gamma nuclides identification; activity determination. Standard nuclides sources were used to calibrate the system. To perform the efficiency x energy calibration a logarithmic fit was applied. Analysis of nuclides with overlapping peaks is allowed by PAGE program. PAGE has additional auxiliary programs for: building and list of isotopic nuclear data libraries; data acquisition from multichannel analyser; spectrum display with automatic area and FWHM determinations. This software is to be applied in analytical process control where time response is a very important parameter. PAGE takes ca. 1.5 minutes to analyse a complex spectrum from a 4096 channels MCA.

    Cho, Y.-C.; Mclachlan, B. G.

    1987-01-01

    A PC based image processing system was employed to determine the instantaneous velocity field of a two-dimensional unsteady flow. The flow was visualized using a suspension of seeding particles in water, and a laser sheet for illumination. With a finite time exposure, the particle motion was captured on a photograph as a pattern of streaks. The streak pattern was digitized and processed using various imaging operations, including contrast manipulation, noise cleaning, filtering, statistical differencing, and thresholding. Information concerning the velocity was extracted from the enhanced image by measuring the length and orientation of the individual streaks. The fluid velocities deduced from the randomly distributed particle streaks were interpolated to obtain velocities at uniform grid points. For the interpolation a simple convolution technique with an adaptive Gaussian window was used. The results are compared with a numerical prediction by a Navier-Stokes computation.

  5. Neurosecretory Habituation in PC12 Cells: Modulation During Parallel Habituation

    Martin, Paul T.; Koshland, Daniel E., Jr.

    1995-05-01

    PC12 cells habituate during repetitive stimulation with acetylcholine, bradykinin, or high potassium. Interspersing these stimulants did not affect the rate of habituation of the others, but it could modulate the amplitude of the norepinephrine secretion each could achieve. Stimulation with acetylcholine inhibited norepinephrine secretion caused by high potassium and bradykinin stimulation, while high potassium had no effect on acetylcholine or bradykinin, and bradykinin increased secretion caused by acetylcholine. Changes in norepinephrine secretion resulting from any of these stimulants correlated with changes in internal calcium levels. Cyclic AMP-, protein kinase C-, and calmodulin-dependent second messenger pathways all modulated norepinephrine secretion caused by acetylcholine and high potassium and showed a distinct hierarchy in their effectiveness. These data demonstrate that different receptor pathways can change the norepinephrine response of one another while not changing the levels of the molecules responsible for habituation.

    To evaluate the practical usefulness of several types of the reporting system especially for radiologists, we have developed and employed several reporting systems. We categorized those reporting systems as follows (1) stand alone PC reporting system; (2) linked reporting system with PACS environment; (3) integrated three-dimensional (3D) imaging workstation (WS) with the intranet. We have evaluated the advantages and disadvantages of those three systems, and compared between the reporting system without PACS and network reporting system with PACS. Using linked reporting system with PACS, radiologists could easily reference both previous reports and archived diagnostic images, and also make their teaching files quickly. In conclusion, the reporting system under PACS environment is found to be practical and helpful for Japanese radiologists. PMID:11378217

  7. Pc5 waves generated by substorm injection: a case study

    Directory of Open Access Journals (Sweden)

    2008-07-01

    Full Text Available We analyzed the spectral-polarized characteristics of Pc5 ULF waves observed on 17 September 2000 after the 03:20:25 UT substorm onset with the satellites GOES 8 and 10 located east and west of the onset location. In the course of the event, the wave polarization changed from mixed (between toroidal and poloidal to poloidal, and then to mixed again. The hodogram of magnetic field oscillations rotated counterclockwise at GOES 8, and clockwise at GOES 10. It is suggested that the satellites detected the waves generated by the substorm injected clouds of the charged particles drifting in the magnetosphere in the opposite azimuthal directions: GOES 8 (located east of the substorm onset detected the wave generated by an electron cloud, and GOES 10 (west of the onset detected the wave generated by a positive ion cloud. This interpretation is confirmed by the energetic particles data recorded by LANL satellites.

  8. Stochastic acceleration of ions driven by Pc1 wave packets

    International Nuclear Information System (INIS)

    The stochastic motion of protons and He+ ions driven by Pc1 wave packets is studied in the context of resonant particle heating. Resonant ion cyclotron heating typically occurs when wave powers exceed 10−4 nT2/Hz. Gyroresonance breaks the first adiabatic invariant and energizes keV ions. Cherenkov resonances with the electrostatic component of wave packets can also accelerate ions. The main effect of this interaction is to accelerate thermal protons to the local Alfven speed. The dependencies of observable quantities on the wave power and plasma parameters are determined, and estimates for the heating extent and rate of particle heating in these wave-particle interactions are shown to be in reasonable agreement with known empirical data

    1991-01-01

    The PC-based Digital Acoustic Control System (DACS), which is a closed-loop system capable of precisely controlling the spectrum in real-time mode, is discussed. The system is based on integrated facility hardware including control microphones, signal conditioners, a real-time analyzer (RTA), a shaper, high capacity power amplifiers, and acoustic horns and generators. The DACS provides both an improved spectrum simulation and realtime information of pertinent test parameters that are stored in five separate files. These files can be hard copied and/or transferred to other programs to obtain a specific format of the test data. It is demonstrated that the computer interface with digital RTA and programmable filters are most effective and efficient. This facility runs independently under the control of a computer with an IEEE-488 interface to the facility hardware.

  12. Tokamak Systems Code

    International Nuclear Information System (INIS)

    The FEDC Tokamak Systems Code calculates tokamak performance, cost, and configuration as a function of plasma engineering parameters. This version of the code models experimental tokamaks. It does not currently consider tokamak configurations that generate electrical power or incorporate breeding blankets. The code has a modular (or subroutine) structure to allow independent modeling for each major tokamak component or system. A primary benefit of modularization is that a component module may be updated without disturbing the remainder of the systems code as long as the imput to or output from the module remains unchanged

  13. IBM-PC based reactor neutronics analysis package

    International Nuclear Information System (INIS)

    The development of a comprehensive system of microcomputer-based codes suitable for neutronics and shielding analysis of nuclear reactors has been undertaken by EG and G Idaho, Inc. at the Idaho National Engineering Laboratory (INEL). This system has been designed for cross section generation, one-dimensional discrete-ordinates analysis, one- two- and three-dimensional diffusion theory analysis, and various other radiation transport applications of interest. Several code modules are now operational, others are still under development. Use of desktop microcomputers rather than mainframe systems for complex scientific calculations offers several distinct advantages. These include economy, user convenience, and local, decentralized control of calculations. In addition to INEL applications, this code system could be extremely useful outside of the National Laboratory environment where access to appropriate mainframe computing systems may be limited. Outside users may include universities and some utilities and consultant organizations

  14. Upgrading of analogue gamma cameras with PC based computer system

    International Nuclear Information System (INIS)

    Full text: Dedicated nuclear medicine computers for acquisition and processing of images from analogue gamma cameras in developing countries are in many cases faulty and technologically obsolete. The aim of the upgrading project of International Atomic Energy Agency (IAEA) was to support the development of the PC based computer system which would cost 5.000 $ in total. Several research institutions from different countries (China, Cuba, India and Slovenia) were financially supported in this development. The basic demands for the system were: one acquisition card an ISA bus, image resolution up to 256x256, SVGA graphics, low count loss at high count rates, standard acquisition and clinical protocols incorporated in PIP (Portable Image Processing), on-line energy and uniformity correction, graphic printing and networking. The most functionally stable acquisition system tested on several international workshops and university clinics was the Slovenian one with a complete set of acquisition and clinical protocols, transfer of scintigraphic data from acquisition card to PC through PORT, count loss less than 1 % at count rate of 120 kc/s, improvement of integral uniformity index by a factor of 3-5 times, reporting, networking and archiving solutions for simple MS network or server oriented network systems (NT server, etc). More than 300 gamma cameras in 52 countries were digitized and put in the routine work. The project of upgrading the analogue gamma cameras yielded a high promotion of nuclear medicine in the developing countries by replacing the old computer systems, improving the technological knowledge of end users on workshops and training courses and lowering the maintenance cost of the departments.

    In this article, the in vitro cytotoxicity of platycodin D was evaluated in human PC-12, SGC-7901, BEL-7402, HeLa and A549 cancer cell lines. PC-12 cells were sensitive to platycodin D treatment, with an IC50 value of 13.5±1.2μM. Morphological and comet assays showed that platycodin D effectively induced apoptosis in PC-12 cells. Platycodin D increased the levels of reactive oxygen species (ROS) and induced a decrease in mitochondrial membrane potential. Platycodin D induced cell cycle arrest at the G0/G1 phase in the PC-12 cell line. Platycodin D can induce autophagy. In addition, platycodin D can down-regulate the expression of Bcl-2 and Bcl-x, and up-regulate the levels of Bid protein in the PC-12 cells. The results demonstrated that platycodin D induced PC-12 cell apoptosis through a ROS-mediated mitochondrial dysfunction pathway. PMID:27294548

  16. Is there a link between proprotein convertase PC7 activity and human lipid homeostasis?

    Directory of Open Access Journals (Sweden)

    Johann Guillemot

    2014-01-01

    Full Text Available A genome-wide association study suggested that a R504H mutation in the proprotein convertase PC7 is associated with increased circulating levels of HDL and reduced triglycerides in black Africans. Our present results show that PC7 and PC7-R504H exhibit similar processing of transferrin receptor-1, proSortilin, and apolipoprotein-F. Plasma analyses revealed no change in the lipid profiles, insulin or glucose of wild type and PC7 KO mice. Thus, the R504H mutation does not modify the proteolytic activity of PC7. The mechanisms behind the implication of PC7 in the regulation of human HDL, triglycerides and in modifying the levels of atherogenic small dense LDL remain to be elucidated.

    Lu, Jun; Zhang, Zhuo; Mo, Juan

    2014-01-01

    The conception of universal combinatorial coding is proposed. Relations exist more or less in many coding methods. It means that a kind of universal coding method is objectively existent. It can be a bridge connecting many coding methods. Universal combinatorial coding is lossless and it is based on the combinatorics theory. The combinational and exhaustive property make it closely related with the existing code methods. Universal combinatorial coding does not depend on the probability statistic characteristic of information source, and it has the characteristics across three coding branches. It has analyzed the relationship between the universal combinatorial coding and the variety of coding method and has researched many applications technologies of this coding method. In addition, the efficiency of universal combinatorial coding is analyzed theoretically. The multicharacteristic and multiapplication of universal combinatorial coding are unique in the existing coding methods. Universal combinatorial coding has theoretical research and practical application value. PMID:24772019

  19. Study of intergranular precipitation in Al 6.8 pc at. Zn and Al 12.1 pc at. Zn

    International Nuclear Information System (INIS)

    As the homogeneous decomposition of alloys with structural hardening is generally accompanied by an heterogeneous precipitation on defects such as dislocations, grain boundaries, and so on, this research thesis reports the study of intergranular precipitation in a Al Zn alloy (Al 15 pc wt.Zn and Al 25 oc wt.Zn) by using transmission electronic microscopy for a local and direct observation of precipitation at grain boundaries. Moreover, possibilities of diffraction of present phases allow their structures and possible epitaxies to be determined. This technique also allows grain boundaries to be analysed and their parameters to be determined. In order to study bare areas and boundary migration, scanning electronic microscopy has been used on massive samples, and X ray analysis has been used on thin ones

  20. Release of full-length PrPC from cultured neurons following neurotoxic challenges

    Directory of Open Access Journals (Sweden)

    Kevin K W Wang

    2012-10-01

    Full Text Available The susceptibility of the normal cellular prion protein isoform, PrPC, to proteolytic digestion has been well documented. In addition, a link between PrPC and the cytosolic protease, calpain, has been reported although the specifics of the interaction remain unclear. We performed in vitro and in cell-based studies to examine this relationship. We observed that human recombinant PrP (HrPrP was readily cleaved by calpain-1 and -2, and we have identified and defined the targeted cleavage sites. In contrast, HrPrP was resistant to caspase-3 digestion. Unexpectedly, when brain lysates from PrPC-expressing mice were treated with calpain, no appreciable loss of the intact PrPC, nor the appearance of PrPC breakdown products (BDPs were observed, even though alpha II-spectrin was converted to its signature calpain-induced BDPs. In addition, when rat cerebrocortical neuronal cultures (RtCNC were subjected to the two neurotoxins at subacute levels, maitotoxin (MTX and N-methyl-D-aspartate (NMDA, PrPC BDPs were also not detectable. However, a novel finding from these cell-based studies is that apparently full-length, mature PrPC is released into culture media from RtCNC challenged with subacute doses of MTX and NMDA. Calpain inhibitor SNJ-1945 and caspase inhibitor IDN-6556 did not attenuate the release of PrPC. Similarly, the lysosomal protease inhibitor, NH4Cl, and the proteasome inhibitor, lactacystin, did not significantly alter the integrity of PrPC or its release from the RtCNC. In conclusion, rat neuronal PrPC is not a significant target for proteolytic modifications during MTX and NMDA neurotoxic challenges. However, the robust neurotoxin-mediated release of full-length PrPC into the cell culture media suggests an unidentified neuroprotective mechanism for PrPC.

    1995-12-01

    A new interactive computer code is presented in this paper for dynamic and soil-structure interaction (SSI) analyses. The computer program FETA (Finite Element Transient Analysis) is a self contained interactive graphics environment for IBM-PC`s that is used for the development of structural and soil models as well as post-processing dynamic analysis output. Full 3-D isometric views of the soil-structure system, animation of displacements, frequency and time domain responses at nodes, and response spectra are all graphically available simply by pointing and clicking with a mouse. FETA`s finite element solver performs 2-D and 3-D frequency and time domain soil-structure interaction analyses. The solver can be directly accessed from the graphical interface on a PC, or run on a number of other computer platforms.

  11. Fracture flow code

    International Nuclear Information System (INIS)

    The hydrology of the SCV site will be modelled utilizing discrete fracture flow models. These models are complex, and can not be fully cerified by comparison to analytical solutions. The best approach for verification of these codes is therefore cross-verification between different codes. This is complicated by the variation in assumptions and solution techniques utilized in different codes. Cross-verification procedures are defined which allow comparison of the codes developed by Harwell Laboratory, Lawrence Berkeley Laboratory, and Golder Associates Inc. Six cross-verification datasets are defined for deterministic and stochastic verification of geometric and flow features of the codes. Additional datasets for verification of transport features will be documented in a future report. (13 figs., 7 tabs., 10 refs.) (authors)

  12. Transformation invariant sparse coding

    2011-01-01

    Sparse coding is a well established principle for unsupervised learning. Traditionally, features are extracted in sparse coding in specific locations, however, often we would prefer invariant representation. This paper introduces a general transformation invariant sparse coding (TISC) model. The...... model decomposes images into features invariant to location and general transformation by a set of specified operators as well as a sparse coding matrix indicating where and to what degree in the original image these features are present. The TISC model is in general overcomplete and we therefore invoke...... sparse coding to estimate its parameters. We demonstrate how the model can correctly identify components of non-trivial artificial as well as real image data. Thus, the model is capable of reducing feature redundancies in terms of pre-specified transformations improving the component identification....

    Hoerth, Matthew T; Drazkowski, Joseph F; Noe, Katherine H; Sirven, Joseph I

    2011-06-01

    Eyewitnesses frequently perceive seizures as life threatening. If an event occurs on the hospital premises, a "code blue" can be called which consumes considerable resources. The purpose of this study was to determine the frequency and characteristics of code blue calls for seizures and seizure mimickers. A retrospective review of a code blue log from 2001 through 2008 identified 50 seizure-like events, representing 5.3% of all codes. Twenty-eight (54%) occurred in inpatients; the other 22 (44%) events involved visitors or employees on the hospital premises. Eighty-six percent of the events were epileptic seizures. Seizure mimickers, particularly psychogenic nonepileptic seizures, were more common in the nonhospitalized group. Only five (17.9%) inpatients had a known diagnosis of epilepsy, compared with 17 (77.3%) of the nonhospitalized patients. This retrospective survey provides insights into how code blues are called on hospitalized versus nonhospitalized patients for seizure-like events. PMID:21546315

    Brehm, Enrico M

    2016-01-01

    In this work, we introduce classical holographic codes. These can be understood as concatenated probabilistic codes and can be represented as networks uniformly covering hyperbolic space. In particular, classical holographic codes can be interpreted as maps from bulk degrees of freedom to boundary degrees of freedom. Interestingly, they are shown to exhibit features similar to those expected from the AdS/CFT correspondence. Among these are a version of the Ryu-Takayanagi formula and intriguing properties regarding bulk reconstruction and boundary representations of bulk operations. We discuss the relation of our findings with expectations from AdS/CFT and, in particular, with recent results from quantum error correction.

    A number of laser propagation codes have been assessed as to their suitability for modeling Army High Energy Laser (HEL) weapons used in an anti- sensor mode. We identify a number of areas in which systems analysis HEL codes are deficient. Most notably, available HEL scaling law codes model the laser aperture as circular, possibly with a fixed (e.g. 10%) obscuration. However, most HELs have rectangular apertures with up to 30% obscuration. We present a beam-quality/aperture shape scaling rela...

    International Nuclear Information System (INIS)

    The Enigma fuel performance code has been developed jointly by BNFL and the CEGB's Berkeley Nuclear Laboratories. Its development arose from the need for a code capable of analysing all aspects of light water reactor (LWR) fuel behaviour which would also provide a suitable framework for future submodel development. The submodels incorporated into Enigma reflect the significant progress which has been made in recent years in modelling the important physical processes which determine fuel behaviour. The Enigma code has been subjected to an extensive programme of validation which has demonstrated its suitability for LWR performance analysis. (author)

    International Nuclear Information System (INIS)

    The FERDOR method is widely used to unfold neutron energy spectra from pulse-height distributions measured with NE-213 spectrometers. Two unfolding codes COOLC (developed at ORNL) and FORIST (modified version of COOLC developed at UIUC) implement the FERDOR method and are distributed by RSIC. Each code package contains an NE-213 response matrix, sample input data, and sample output. The smoothing (window) widths which are distributed with COOLC are not the most appropriate for all neutron spectrum measurements. The FORIST code determines an optimum set of window widths according to the desired statistical error in the smoothed spectrum

  9. RHIC PC CNI POLARIMETER: EXPERIMENTAL SETUP AND PHYSICS RESULTS

    International Nuclear Information System (INIS)

    Acceleration of polarized proton beams and experiments with them at RHIC require fast and reliable measurements of the polarization. The polarimeter presented here uses very high figure of merit of the elastic pC scattering at very low momenta transfer since the cross section is large. Small (a few percent) analyzing power of the reaction makes it necessary to collect about 107 events per measurement. A deadtimeless DAQ system for the polarimeter is discussed in this paper. It is based on the waveform digitizer modules with ''on-board''' event analysis, resulting in typical polarization measurement times of several tens of seconds. During winter 2001/2002 RHIC polarized run several dedicated data runs were taken by the polarimeter to extract the form of the analyzing power dependence as a function of the momentum transferred at beam energies 24 and 100 GeV. This dependence is extremely important for the theoretical understanding of the CNI process including the contribution of the spin-flip hadronic amplitude. The new data may become an input to some theoretical models predicting the energy dependence of the analyzing power

    Safe monitoring of foetal heart rate is a valuable tool for the healthy evolution and wellbeing of both foetus and mother. This paper presents a non-invasive optical technique that allows for foetal heart rate detection using a photovoltaic infrared (IR) detector placed on the mother's abdomen. The system presented here consists of a photoplethysmography (PPG) circuit, abdomen circuit and a personal computer equipped with MATLAB. A near IR beam having a wavelength of 880 nm is transmitted through the mother's abdomen and foetal tissue. The received abdominal signal that conveys information pertaining to the mother and foetal heart rate is sensed by a low noise photodetector. The PC receives the signal through the National Instrumentation Data Acquisition Card (NIDAQ). After synchronous detection of the abdominal and finger PPG signals, the designed MATLAB-based software saves, analyses and extracts information related to the foetal heart rate. Extraction is carried out using recursive least squares adaptive filtration. Measurements on eight pregnant women with gestational periods ranging from 35-39 weeks were performed using the proposed system and CTG. Results show a correlation coefficient of 0.978 and a correlation confidence interval between 88-99.6%. The t test results in a p value of 0.034, which is less than 0.05. Low power, low cost, high signal-to-noise ratio, reduction of ambient light effect and ease of use are the main characteristics of the proposed system. PMID:24195701

    2002-01-01

    We present adaptive optics assisted OASIS integral field spectrography of the S0 galaxy NGC 4621. Two-dimensional stellar kinematical maps (mean velocity and dispersion) reveal the presence of a 60 pc diameter counter-rotating core (CRC), the smallest observed to date. The OASIS data also suggests that the kinematic center of the CRC is slightly offset from the center of the outer isophotes. This seems to be confirmed by archival HST/STIS data. We also present the HST/WFPC2 V-I colour map, which exhibits a central elongated red structure, also slightly off-centered in the same direction as the kinematic centre. We then construct an axisymmetric model of NGC 4621: the two-integral distribution function is derived using the Multi-Gaussian Expansion and the Hunter & Qian (1993) formalisms. Although the stellar velocities are reasonably fitted, including the region of the counter-rotating core, significant discrepancies between the model and the observations demonstrate the need for a more general model (e.g....

    We report the discovery of a transient radio source 2.7 arcsec (0.1 pc projected distance) South of the Galactic Center massive black hole, Sagittarius A*. The source flared with a peak of at least 80 mJy in March 2004. The source was resolved by the Very Large Array into two components with a separation of ~0.7 arcsec and characteristic sizes of ~0.2 arcsec. The two components of the source faded with a power-law index of 1.1 +/- 0.1. We detect an upper limit to the proper motion of the Eastern component of ~3 x 10^3 km s^-1 relative to Sgr A*. We detect a proper motion of ~10^4 km s^-1 for the Western component relative to Sgr A*. The transient was also detected at X-ray wavelengths with the Chandra X-ray Observatory and the XMM-Newton telescope and given the designation CXOGC J174540.0-290031. The X-ray source falls in between the two radio components. The maximum luminosity of the X-ray source is ~10^36 erg s^-1, significantly sub-Eddington.

    The NA48 experiment at the CERN SPS measures the direct CP violation parameter Re( epsilon '/z) in the neutral kaon system with an intended precision of 2*10/sup -4/. Thus, the data acquisition system has to handle peak rates up to 150 MByte/s during a 2.5 s beam burst and flat rates up to 20 MByte/s during on-line processing. The NA48 on-line PC farm includes 24 PentiumII-266 MHz PCs connected via switched fast ethernet network. This farm receives data from the detector systems and performs event building. Afterwards the data are transferred via an optical gigabit ethernet link to the NA48 central data recording system at CERN computer center. In addition, trigger and checking processes can be applied. The software on the farm is implemented as client/server applications and represents a highly flexible, fail safe, and scalable system. During data taking, in 1999, 100 TByte were collected, processed, and stored by the acquisition system with an overall efficiency of 99%. (5 refs).

    1991-02-01

    The Hanford Unified Dose Utility (HUDU) computer program was developed to provide rapid initial assessment of radiological emergency situations. The HUDU code uses a straight-line Gaussian atmospheric dispersion model to estimate the transport of radionuclides released from an accident site. For dose points on the plume centerline, it calculates internal doses due to inhalation and external doses due to exposure to the plume. The program incorporates a number of features unique to the Hanford Site (operated by the US Department of Energy), including a library of source terms derived from various facilities' safety analysis reports. The HUDU code was designed to run on an IBM-PC or compatible personal computer. The user interface was designed for fast and easy operation with minimal user training. The theoretical basis and mathematical models used in the HUDU computer code are described, as are the computer code itself and the data libraries used. Detailed instructions for operating the code are also included. Appendices to the report contain descriptions of the program modules, listings of HUDU's data library, and descriptions of the verification tests that were run as part of the code development. 14 refs., 19 figs., 2 tabs.

    2016-01-01

    Exosomes are small extracellular vesicles containing microRNAs and mRNAs that are produced by various types of cells. We previously used ultrafiltration and size-exclusion chromatography to isolate two types of human salivary exosomes (exosomes I, II) that are different in size and proteomes. We showed that salivary exosomes contain large repertoires of small RNAs. However, precise information regarding long RNAs in salivary exosomes has not been fully determined. In this study, we investigated the compositions of protein-coding RNAs (pcRNAs) and long non-protein-coding RNAs (lncRNAs) of exosome I, exosome II and whole saliva (WS) by next-generation sequencing technology. Although 11% of all RNAs were commonly detected among the three samples, the compositions of reads mapping to known RNAs were similar. The most abundant pcRNA is ribosomal RNA protein, and pcRNAs of some salivary proteins such as S100 calcium-binding protein A8 (protein S100-A8) were present in salivary exosomes. Interestingly, lncRNAs of pseudogenes (presumably, processed pseudogenes) were abundant in exosome I, exosome II and WS. Translationally controlled tumor protein gene, which plays an important role in cell proliferation, cell death and immune responses, was highly expressed as pcRNA and pseudogenes in salivary exosomes. Our results show that salivary exosomes contain various types of RNAs such as pseudogenes and small RNAs, and may mediate intercellular communication by transferring these RNAs to target cells as gene expression regulators.

    The FAST Code which is capable of determining structural loads on a flexible, teetering, horizontal axis wind turbine is described and comparisons of calculated loads with test data are given at two wind speeds for the ESI-80. The FAST Code models a two-bladed HAWT with degrees of freedom for blade bending, teeter, drive train flexibility, yaw, and windwise and crosswind tower motion. The code allows blade dimensions, stiffnesses, and weights to differ and models tower shadow, wind shear, and turbulence. Additionally, dynamic stall is included as are delta-3 and an underslung rotor. Load comparisons are made with ESI-80 test data in the form of power spectral density, rainflow counting, occurrence histograms, and azimuth averaged bin plots. It is concluded that agreement between the FAST Code and test results is good. (au)

  4. Induction technology optimization code

    International Nuclear Information System (INIS)

    A code has been developed to evaluate relative costs of induction accelerator driver systems for relativistic klystrons. The code incorporates beam generation, transport and pulsed power system constraints to provide an integrated design tool. The code generates an injector/accelerator combination which satisfies the top level requirements and all system constraints once a small number of design choices have been specified (rise time of the injector voltage and aspect ratio of the ferrite induction cores, for example). The code calculates dimensions of accelerator mechanical assemblies and values of all electrical components. Cost factors for machined parts, raw materials and components are applied to yield a total system cost. These costs are then plotted as a function of the two design choices to enable selection of an optimum design based on various criteria. (Author) 11 refs., 3 figs

    Full Text Available In this research, the composites between polycarbonate (PC and acrylonitrile-butadiene-styrene (ABS alloy and Kevlar fiber were prepared. The flexural and tensile properties of PC/ABS alloy and its composites were determined using a universal testing machine. The synergistic behavior of flexural modulus was observed for all regions of PC contents, while the synergism of flexural strength and tensile strength were found in some PC contents. It was found that the optimum weight ratio of PC:ABS was 60:40. In the Kevlar Fiber-reinforced PC/ABS composite system at PC:ABS of 60:40, both flexural modulus and strength were increased with matrix contents. Additionally, the flexural strength drastically increased with the matrix content and then reached the maximum value of 167 MPa at the matrix content of 33.4 wt%. The results from peel test, water contact measurement, and scanning electron microscopy (SEM reveal that the interfacial adhesion between the Kevlar fiber and the polymer matrix could be improved by increasing the PC content in the matrix.

    Invasive aspergillosis (IA) has become increasingly common and is characterised by high morbidity and mortality. Upcoming resistance threatens treatment with azoles and highlights the continuous need for novel therapeutics. This laboratory study investigated the in vitro and in vivo potential of the alkylphospholipid oleylphosphocholine (OlPC) against Aspergillus. In vitro activities of OlPC, miltefosine, posaconazole and voriconazole were determined for Aspergillus fumigatus, A. niger, A. terreus and A. flavus. In vivo efficacy of OlPC was evaluated in a systemic A. fumigatus mouse model, adopting a short-term and long-term oral or intraperitoneal dosing regimen. OlPC showed good in vitro activity against A. fumigatus (IC50 = 1.04 μmol l(-1)). Intraperitoneal administration of 50 mg kg(-1) day(-1) OlPC significantly reduced the fungal organ burdens at 4 days post-infection (dpi). Although 5- and 10-day OlPC treatment improved survival, organ burdens were not affected at 10 and 15 dpi. While this study showed excellent in vitro activity of OlPC against Aspergillus spp., its therapeutic efficacy in an acute mouse model for IA was less convincing. Given the limited therapeutic options in the current antifungal market for invasive infections, OlPC activity should be assessed in a less stringent in vivo model, potentially in combination treatment with other already marketed antifungal drugs.

    Background A number of studies have shown that oxidative stress and mitochondrial involvement are major triggering factors in the development of neurodegenerative diseases. Cobalt chloride (CoCl_2)-induced cell death in PC12 cells may serve a simple and convenient in vitro model of hypoxia-induced neuronal cytotoxicity. To explore the effect of geniposide on CoCl_2 which induced cytotoxicity and mitochondrial function in rat pheochromocytoma PC12 cells, we analyzed the influence of geniposide on the expression of apoptosis-related proteins. Methods PC12 cells and RNAi PC12 cells were treated with 0, 12.5, 25, 50, 100 μmol/L geniposide for 12 hours and then exposure to 400 μmol/L CoCl_2 for 12 hours. Cell viability, cell morphology, and expression of Bcl-2, Bax, P53 and caspase-9 were determined using Western blotting. Results Pretreatment with geniposide markedly improved the cells viability and morphology, decreased the expression of Bax, P53 and caspase-9, and increased the expression of Bcl-2 in PC12 cells challenged by CoCl_2. However, in the RNAi PC12 cells, geniposide had no significant effect on the expression of these proteins. Conclusion Geniposide protects PC12 cells from CoCl_2 involved in mitochondrial mediated apoptosis, and GLP-1 R might play a critical role in the neuroprotection of geniposide in PC12 cells.

    This paper deals with the magnetic and electrical properties of the unsolvated crystals of bisphthalocyaninato lutetium, Pc2Lu. The crystalline structure and the magnetic properties determined by ESR reveal a bidimensional spin diffusion in this system. The conductivity measurements show that Pc 2Lu crystals are extrinsic molecular semiconductors.

    Channell, P.J.; Healy, L.M.; Lysenko, W.P.

    1985-10-01

    This paper describes the status of BEDLAM and presents the results of some tests. We simulated a section of radio-frequency quadrupole (RFQ) linac, neglecting space charge, to test the new code. Agreement with a Particle-In-Cell (PIC) simulation was excellent. We also verified that the fourth-order solution is more accurate than the second-order solution, which indicates the convergence of the method. We believe these results justify the continued development of moment simulation codes.

    Systems code is often written in low-level languages like C/C++, which offer many benefits but also delegate memory management to programmers. This invites memory safety bugs that attackers can exploit to divert control flow and compromise the system. Deployed defense mechanisms (e.g., ASLR, DEP) are incomplete, and stronger defense mechanisms (e.g., CFI) often have high overhead and limited guarantees [19, 15, 9]. We introduce code-pointer integrity (CPI), a new design point that guarantees...

  20. Towards advanced code simulators

    International Nuclear Information System (INIS)

    The Central Electricity Generating Board (CEGB) uses advanced thermohydraulic codes extensively to support PWR safety analyses. A system has been developed to allow fully interactive execution of any code with graphical simulation of the operator desk and mimic display. The system operates in a virtual machine environment, with the thermohydraulic code executing in one virtual machine, communicating via interrupts with any number of other virtual machines each running other programs and graphics drivers. The driver code itself does not have to be modified from its normal batch form. Shortly following the release of RELAP5 MOD1 in IBM compatible form in 1983, this code was used as the driver for this system. When RELAP5 MOD2 became available, it was adopted with no changes needed in the basic system. Overall the system has been used for some 5 years for the analysis of LOBI tests, full scale plant studies and for simple what-if studies. For gaining rapid understanding of system dependencies it has proved invaluable. The graphical mimic system, being independent of the driver code, has also been used with other codes to study core rewetting, to replay results obtained from batch jobs on a CRAY2 computer system and to display suitably processed experimental results from the LOBI facility to aid interpretation. For the above work real-time execution was not necessary. Current work now centers on implementing the RELAP 5 code on a true parallel architecture machine. Marconi Simulation have been contracted to investigate the feasibility of using upwards of 100 processors, each capable of a peak of 30 MIPS to run a highly detailed RELAP5 model in real time, complete with specially written 3D core neutronics and balance of plant models. This paper describes the experience of using RELAP5 as an analyzer/simulator, and outlines the proposed methods and problems associated with parallel execution of RELAP5

    In recent work, various fractal image coding methods are reported, which adopt the self-similarity of images to compress the size of images. However, till now, no solutions for the security of fractal encoded images have been provided. In this paper, a secure fractal image coding scheme is proposed and evaluated, which encrypts some of the fractal parameters during fractal encoding, and thus, produces the encrypted and encoded image. The encrypted image can only be recovered by the correct ke...

    Behavioral, anatomical, and physiological approaches can be integrated in the study of sound localization in barn owls. Space representation in owls provides a useful example for discussion of place and ensemble coding. Selectivity for space is broad and ambiguous in low-order neurons. Parallel pathways for binaural cues and for different frequency bands converge on high-order space-specific neurons, which encode space more precisely. An ensemble of broadly tuned place-coding neurons may conv...

  4. PEAR code review

    International Nuclear Information System (INIS)

    As a necessary component in the continuous improvement and refinement of methodologies employed in the nuclear industry, regulatory agencies need to periodically evaluate these processes to improve confidence in results and ensure appropriate levels of safety are being achieved. The independent and objective review of industry-standard computer codes forms an essential part of this program. To this end, this work undertakes an in-depth review of the computer code PEAR (Public Exposures from Accidental Releases), developed by Atomic Energy of Canada Limited (AECL) to assess accidental releases from CANDU reactors. PEAR is based largely on the models contained in the Canadian Standards Association (CSA) N288.2-M91. This report presents the results of a detailed technical review of the PEAR code to identify any variations from the CSA standard and other supporting documentation, verify the source code, assess the quality of numerical models and results, and identify general strengths and weaknesses of the code. The version of the code employed in this review is the one which AECL intends to use for CANDU 9 safety analyses. (author)

  5. On Expanded Cyclic Codes

    2008-01-01

    The paper has a threefold purpose. The first purpose is to present an explicit description of expanded cyclic codes defined in $\\GF(q^m)$. The proposed explicit construction of expanded generator matrix and expanded parity check matrix maintains the symbol-wise algebraic structure and thus keeps many important original characteristics. The second purpose of this paper is to identify a class of constant-weight cyclic codes. Specifically, we show that a well-known class of $q$-ary BCH codes excluding the all-zero codeword are constant-weight cyclic codes. Moreover, we show this class of codes achieve the Plotkin bound. The last purpose of the paper is to characterize expanded cyclic codes utilizing the proposed expanded generator matrix and parity check matrix. We analyze the properties of component codewords of a codeword and particularly establish the precise conditions under which a codeword can be represented by a subbasis. With the new insights, we present an improved lower bound on the minimum distance of...

  6. KENO-V code

    International Nuclear Information System (INIS)

    The KENO-V code is the current release of the Oak Ridge multigroup Monte Carlo criticality code development. The original KENO, with 16 group Hansen-Roach cross sections and P1 scattering, was one ot the first multigroup Monte Carlo codes and it and its successors have always been a much-used research tool for criticality studies. KENO-V is able to accept large neutron cross section libraries (a 218 group set is distributed with the code) and has a general P/sub N/ scattering capability. A supergroup feature allows execution of large problems on small computers, but at the expense of increased calculation time and system input/output operations. This supergroup feature is activated automatically by the code in a manner which utilizes as much computer memory as is available. The primary purpose of KENO-V is to calculate the system k/sub eff/, from small bare critical assemblies to large reflected arrays of differing fissile and moderator elements. In this respect KENO-V neither has nor requires the many options and sophisticated biasing techniques of general Monte Carlo codes

  7. Introduction and preparation of the nuclear fuel cycle facility risk analysis code: STAR

    International Nuclear Information System (INIS)

    STAR code is a computer program, by which one can perform the probabilistic safety assessment (PSA) for the nuclear fuel cycle facility in both the normal and the accidental event of environmental radioactive material release. This code was originally developed by NUKEM GmbH in West Germany as a fruit of the PSE (Projekt Sicherheitsstudien Entsorgung) aiming at R and D of safety analysis methods for use in nuclear fuel cycle facilities such as reprocessing plants. In JAERI, efforts have been made to research and develop safety assessment methods applicable to the accidental situations assumed to happen in the reprocessing plants. In this line of objectives, the STAR code was introduced from NUKEM GmbH in 1986 and, since then, has been improved and prepared to add an ability to analyze public radiation exposure by released activities from the plants. At the first stage of this code preparation, the program conversion was made to adapt the STAR code, originally operative on IBM-compatible PC's and Hewlett Packard 7550A plotters, to NEC PC 9801RX and NEC PR 602R page printers installed in the Fuel Cycle Safety Assessment Laboratory of JAERI. This report describes calculational performances of the STAR code, results of the improvement and preparation works together with input/output data format in illustration of a sample HALW (High Activity Liquid Waste) tank PSA problem, thus making a users' manual for the STAR code.

    We examined the expression and localization of the prohormone convertases, PC1 and PC2, in the ultimobranchial gland of the adult bullfrog using immunohistochemical (IHC) and in situ hybridization (ISH) techniques. In the ultimobranchial gland, PC1-immunoreactive cells were columnar, and were present in the follicular epithelium. When serial sections were immunostained with anti-calcitonin, anti-CGRP, anti-PC1, and anti-PC2 sera, PC1 was found only in the calcitonin/CGRP-producing cells. No PC2-immunopositive cells were detected. In the ISH, PC1 mRNA-positive cells were detected in the follicle cells in the ultimobranchial gland. No PC2 mRNA-positive cells were detected. RT-PCR revealed expression of the mRNAs of PC1 and the PC2 in the ultimobranchial gland. However, very little of the PC2 mRNA is probably translated because no PC2 protein was detected either by IHC staining or by Western blotting analysis. We conclude that the main prohormone convertase that is involved in the proteolytic cleavage of procalcitonin in the bullfrog is PC1. PMID:14566018

  9. Photodynamic Therapy with the Silicon Phthalocyanine Pc 4 Induces Apoptosis in Mycosis Fungoides and Sezary Syndrome

    2010-01-01

    Full Text Available Our current focus on the effects of Photodynamic Therapy (PDT using silicon phthalocyanine Pc 4 photosensitizer on malignant T lymphocytes arose due to preclinical observations that Jurkat cells, common surrogate for human T cell lymphoma, were more sensitive to Pc 4-PDT-induced killing than epidermoid carcinoma A431 cells. Mycosis fungoides (MF as well as Sezary syndrome (SS are variants of cutaneous T-cell lymphoma (CTCL in which malignant T-cells invade the epidermis. In this study, we investigated the cytotoxicity of Pc 4-PDT in peripheral blood cells obtained from patients with SS and in skin biopsies of patients with MF. Our data suggest that Pc 4-PDT preferentially induces apoptosis of CD4+CD7− malignant T-lymphocytes in the blood relative to CD11b+ monocytes and nonmalignant T-cells. In vivo Pc 4-PDT of MF skin also photodamages the antiapoptotic protein Bcl-2.

  10. Reuse of the compact nuclear simulator software under PC with Linux

    International Nuclear Information System (INIS)

    This study was approached to reuse source programs for a nuclear simulator under PC with Open Source Software(OSS) and to extend its applicability. Source programs in the Compact Nuclear Simulator(CNS), which has been operated for institutional research and training in KAERI, were reused and implemented for Linux-PC environment with the aim of supporting the study. PC with 500 MHz processor and Linux 2.2.5-22 kernel were utilized for the reuse implementation and it was investigated for some applications, through the functional testing for its main functions as interfaced with compact control panels in the current CNS. Development and upgrade of small-scale simulators, establishment of process simulation for PC, and development of prototype predictive simulation, can effectively be enabled with the experience though the reuse implementation was limited to port only CNS programs for PC with Linux

  11. Phase Behavior, Thermal Stability and Rheological Properties of PPEK/PC Blends

    Institute of Scientific and Technical Information of China (English)

    2002-01-01

    Phase behavior, thermal stability and rheological properties of the blends of poly(phthalazinone ether ketone) (PPEK)with bisphenol-A polycarbonate (PC) prepared by solution coprecipitation were studied using differential scanning calorimetry (DSC), Frourier-Transform IR spectroscopy (FT-IR), thermogravimetric analysis (TGA) and capillary rheometer. The DSC results indicated that PPEK/PC blends are almost immiscible in full compositions. FT-IR investigation showed that there were no apparent specific interactions between the constituent polymers. The blends keep excellent thermal stability and the addition of PC degrades the thermal stability of blends to some degree. The thermal degradation processes of the blends are much similar to that of PC. The studies on rheological properties of blends show that blending PPEK with PC is beneficial to reducing the melt viscosity and improving the appearance of PPEK.

    Background: It is extensively supposed that vegetarian diet could affect cancer progress and increase the influence of formal chemotherapy. Objectives: The present study was designed to determine the effect of the ethanol Bane skin extract against chemo resistant prostate cancer PC3 cells. Materials and Methods: PC3 and L929 cells were cultivated and then incubated in the ethanol Bane skin extract with various concentrations of 0.78, 1.5, 3.13, 6.25, 12.5 mg/mL in 3 times 24, 48, 72 hours. Cytotoxic effect of the ethanol Bane skin extract on PC3 and L929 cells was examined by MTT assay after 24, 48, and 72 hours. Morphology of PC3 cells was evaluated by Gimsa staining. Results: The ethanol Bane skin extract inhibited proliferation and caused cell death with IC50 values of 2.8 mg/mL on PC3 cells and the IC50 was 6.1 mg/mL on l929 cells. Morphological changes and apoptotic bodies were observed in PC3 cells faced with the ethanol Bane skin extract by staining with Gimsa. Conclusions: The ethanol Bane skin extract could repress the growth of PC3 cell line. This inhibitory effect of the Bane extract depended on the dose and the time on PC3. The result of this study shows that the ethanol Bane skin extract includes photochemical and inhibitory function against proliferation and inducer of apoptosis in human prostate cancer PC3 cells and also has less cytotoxic effect on l929 than PC3 cells. The ethanol Bane skin extract might be a good candidate for the new herbal anticancer drug. PMID:27482333

  14. Manganese oxidation state mediates toxicity in PC12 cells

    International Nuclear Information System (INIS)

    The role of the manganese (Mn) oxidation state on cellular Mn uptake and toxicity is not well understood. Therefore, undifferentiated PC12 cells were exposed to 0-200 μM Mn(II)-chloride or Mn(III)-pyrophosphate for 24 h, after which cellular manganese levels were measured along with measures of cell viability, function, and cytotoxicity (trypan blue exclusion, medium lactate dehydrogenase (LDH), 8-isoprostanes, cellular ATP, dopamine, serotonin, H-ferritin, transferrin receptor (TfR), Mn-superoxide dismutase (MnSOD), and copper-zinc superoxide dismutase (CuZnSOD) protein levels). Exposures to Mn(III) >10 μM produced 2- to 5-fold higher cellular manganese levels than equimolar exposures to Mn(II). Cell viability and ATP levels both decreased at the highest Mn(II) and Mn(III) exposures (150-200 μM), while Mn(III) exposures produced increases in LDH activity at lower exposures (≥50 μM) than did Mn(II) (200 μM only). Mn(II) reduced cellular dopamine levels more than Mn(III), especially at the highest exposures (50% reduced at 200 μM Mn(II)). In contrast, Mn(III) produced a >70% reduction in cellular serotonin at all exposures compared to Mn(II). Different cellular responses to Mn(II) exposures compared to Mn(III) were also observed for H-ferritin, TfR, and MnSOD protein levels. Notably, these differential effects of Mn(II) versus Mn(III) exposures on cellular toxicity could not simply be accounted for by the different cellular levels of manganese. These results suggest that the oxidation state of manganese exposures plays an important role in mediating manganese cytotoxicity

  15. Conversion of a mainframe simulation for maintenance performance to a PC environment

    International Nuclear Information System (INIS)

    The computer model MAPPS, the Maintenance Personnel Performance Simulation, has been developed and validated by the US NRC [Nuclear Regulatory Commission] in order to improve maintenance practices and procedures at nuclear power plants. This model has now been implemented and improved, in a PC [personal computer] environment and renamed MICROMAPPS. The model is stochastically based and users are able to simulate the performance of 2- to 8-person crews for a variety of maintenance tasks under a variety of conditions. These conditions include aspects of crew actions as potentially influenced by the task, the environment, or the personnel involved. For example, the influence of the following factors is currently modeled within the MAPPS computer code: (1) personnel characteristics include but are not limited to intellectual and perceptual motor ability levels, the effect of fatigue and conversely, of rest breaks on performance, stress, communication, supervisor acceptance, motivation, organizational climate, time since the tasks was last performed and the staffing level available; (2) task variables include but are not limited to time allowed, occurrence of shift change, intellectual requirements, perceptual motor requirements, procedures quality, necessity for protective clothing and essentiality of a procedures quality, necessity for protective clothing and essentiality of a subtask; and (3) environment variables include temperature of the workplace, radiation level, and noise levels. The output describing maintainer performance includes subtask and task identification, success proportion, work and wait durations, time spent repeating various subtasks and outcome in terms of errors detected by the crew, false alarms, undetected errors, duration, and the probability of success. The model is comprehensive and allows for the modeling of decision making, trouble-shooting and branching of tasks

    ESO is currently in the final phase of the standardization process for PC-based Programmable Logical Controllers (PLCs) as the new platform for the development of control systems for future VLT/VLTI instruments. The standard solution used until now consists of a Local Control Unit (LCU), a VME-based system having a CPU and commercial and proprietary boards. This system includes several layers of software and many thousands of lines of code developed and maintained in house. LCUs have been used for several years as the interface to control instrument functions but now are being replaced by commercial off-the-shelf (COTS) systems based on BECKHOFF Embedded PCs and the EtherCAT fieldbus. ESO is working on the completion of the software framework that enables a seamless integration into the VLT control system in order to be ready to support upcoming instruments like ESPRESSO and ERIS, that will be the first fully VLT compliant instruments using the new standard. The technology evaluation and standardization process has been a long and combined effort of various engineering disciplines like electronics, control and software, working together to define a solution that meets the requirements and minimizes the impact on the observatory operations and maintenance. This paper presents the challenges of the standardization process and the steps involved in such a change. It provides a technical overview of how industrial standards like EtherCAT, OPC-UA, PLCOpen MC and TwinCAT can be used to replace LCU features in various areas like software engineering and programming languages, motion control, time synchronization and astronomical tracking.

  17. Radiation shielding and transport codes and data libraries for personal computers available from the Radiation Shielding Information Center

    International Nuclear Information System (INIS)

    In nuclear applications, the conversion of mainframe software to the personal computer (PC) environment has seen an accelerated pace. Credit has to be extended to the software companies that have made the scientific language FORTRAN available on PCs. Not to be neglected are the scientists who dedicate their time in the conversion of codes and are challenged by the limited PC memory and disk space. The Radiation shielding Information Center (RSIC) at Oak Ridge National Laboratory has encouraged these developments, and the shielding community has cooperated by making these new tools available via RSIC. The PC codes in the shielding and radiation transport area are divided into five categories (these categories are not mutually exclusive): (1) gamma-ray scattering; (2) neutron and gamma-ray transport (also coupled); (3) environmental dose; (4) medical applications; and (5) reactor physics. Each category is discussed
