BASE - 2nd generation software for microarray data management and analysis  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Microarray experiments are increasing in size and samples are collected asynchronously over long time. Available data are re-analysed as more samples are hybridized. Systematic use of collected data requires tracking of biomaterials, array information, raw data, and assembly of annotations. To meet the information tracking and data analysis challenges in microarray experiments we reimplemented and improved BASE version 1.2. Results The new BASE presented in this report is a comprehensive annotable local microarray data repository and analysis application providing researchers with an efficient information management and analysis tool. The information management system tracks all material from biosource, via sample and through extraction and labelling to raw data and analysis. All items in BASE can be annotated and the annotations can be used as experimental factors in downstream analysis. BASE stores all microarray experiment related data regardless if analysis tools for specific techniques or data formats are readily available. The BASE team is committed to continue improving and extending BASE to make it usable for even more experimental setups and techniques, and we encourage other groups to target their specific needs leveraging on the infrastructure provided by BASE. Conclusion BASE is a comprehensive management application for information, data, and analysis of microarray experiments, available as free open source software at http://base.thep.lu.se under the terms of the GPLv3 license.

2nd Generation alkaline electrolysis. Final report  

Energy Technology Data Exchange (ETDEWEB)

The overall purpose of this project has been to contribute to this load management by developing a 2{sup nd} generation of alkaline electrolysis system characterized by being compact, reliable, inexpensive and energy efficient. The specific targets for the project have been to: 1) Increase cell efficiency to more than 88% (according to the higher heating value (HHV)) at a current density of 200 mA /cm{sup 2}; 2) Increase operation temperature to more than 100 degree Celsius to make the cooling energy more valuable; 3) Obtain an operation pressure more than 30 bar hereby minimizing the need for further compression of hydrogen for storage; 4) Improve stack architecture decreasing the price of the stack with at least 50%; 5) Develop a modular design making it easy to customize plants in the size from 20 to 200 kW; 6) Demonstrating a 20 kW 2{sup nd} generation stack in H2College at the campus of Arhus University in Herning. The project has included research and development on three different technology tracks of electrodes; an electrochemical plating, an atmospheric plasma spray (APS) and finally a high temperature and pressure (HTP) track with operating temperature around 250 deg. C and pressure around 40 bar. The results show that all three electrode tracks have reached high energy efficiencies. In the electrochemical plating track a stack efficiency of 86.5% at a current density of 177mA/cm{sup 2} and a temperature of 74.4 deg. C has been shown. The APS track showed cell efficiencies of 97%, however, coatings for the anode side still need to be developed. The HTP cell has reached 100 % electric efficiency operating at 1.5 V (the thermoneutral voltage) with a current density of 1. 1 A/cm{sup 2}. This track only tested small cells in an externally heated laboratory set-up, and thus the thermal loss to surroundings cannot be given. The goal set for the 2{sup nd} generation electrolyser system, has been to generate 30 bar pressure in the cell stack. An obstacle to be overcomed has been to ensure equalisation of the H{sub 2} and O{sub 2} pressure to avoid that mixing of gasses can occur. To solve this problem, a special equilibrium valve has been developed to mechanically control that the pressure of the H{sub 2} at all times equals the O{sub 2} side. The developments have resulted in a stack design, which is a cylindrical pressure vessel, with each cell having a cell ''wall'' sufficiently thick, to resist the high pressure and sealed with O-rings for perfect sealing at high pressures. The stack has in test proved to resist a pressure on 45 bar, though some adjustment is still needed to optimize the pressure resistance and efficiency. When deciding on the new stack design both a 'zero gap' and 'non-zero gap' was considered. The zero gap design is more efficient than non-zero gap, however the design is more complex and very costly, primarily because the additional materials and production costs for zero gap electrodes. From these considerations, the concept of a ''low gap'', low diameter, high pressure and high cell number electrolyser stack was born, which could offer an improved efficiency of the electrolyser without causing the same high material and production cost as a zero gap zero gap solution. As a result the low gap design and pressurized stack has reduced the price by 60% of the total system, as well as a reduced system footprint. The progress of the project required a special focus on corrosion testing and examination of polymers in order to find alternative durable membrane and gasket materials. The initial literature survey and the first tests indicated that the chemical resistance of polymers presented a greater challenge than anticipated, and that test data from commercial suppliers were insufficient to model the conditions in the electrolyser. The alkali resistant polymers (e.g. Teflon) are costly and the search for cheaper alternatives turned into a major aim. A number of different tests were run under accelerated conditions and the degradation mechani

The 2nd Generation Real Time Mission Monitor (RTMM) Development  

Science.gov (United States)

The NASA Real Time Mission Monitor (RTMM) is a visualization and information system that fuses multiple Earth science data sources, to enable real time decisionmaking for airborne and ground validation experiments. Developed at the National Aeronautics and Space Administration (NASA) Marshall Space Flight Center, RTMM is a situational awareness, decision-support system that integrates satellite imagery and orbit data, radar and other surface observations (e.g., lightning location network data), airborne navigation and instrument data sets, model output parameters, and other applicable Earth science data sets. The integration and delivery of this information is made possible using data acquisition systems, network communication links, network server resources, and visualizations through the Google Earth virtual globe application. In order to improve the usefulness and efficiency of the RTMM system, capabilities are being developed to allow the end-user to easily configure RTMM applications based on their mission-specific requirements and objectives. This second generation RTMM is being redesigned to take advantage of the Google plug-in capabilities to run multiple applications in a web browser rather than the original single application Google Earth approach. Currently RTMM employs a limited Service Oriented Architecture approach to enable discovery of mission specific resources. We are expanding the RTMM architecture such that it will more effectively utilize the Open Geospatial Consortium Sensor Web Enablement services and other new technology software tools and components. These modifications and extensions will result in a robust, versatile RTMM system that will greatly increase flexibility of the user to choose which science data sets and support applications to view and/or use. The improvements brought about by RTMM 2nd generation system will provide mission planners and airborne scientists with enhanced decision-making tools and capabilities to more efficiently plan, prepare and execute missions, as well as to playback and review past mission data. To paraphrase the old television commercial RTMM doesn t make the airborne science, it makes the airborne science easier.

Super Boiler 2nd Generation Technology for Watertube Boilers  

Energy Technology Data Exchange (ETDEWEB)

This report describes Phase I of a proposed two phase project to develop and demonstrate an advanced industrial watertube boiler system with the capability of reaching 94% (HHV) fuel-to-steam efficiency and emissions below 2 ppmv NOx, 2 ppmv CO, and 1 ppmv VOC on natural gas fuel. The boiler design would have the capability to produce >1500 F, >1500 psig superheated steam, burn multiple fuels, and will be 50% smaller/lighter than currently available watertube boilers of similar capacity. This project is built upon the successful Super Boiler project at GTI. In that project that employed a unique two-staged intercooled combustion system and an innovative heat recovery system to reduce NOx to below 5 ppmv and demonstrated fuel-to-steam efficiency of 94% (HHV). This project was carried out under the leadership of GTI with project partners Cleaver-Brooks, Inc., Nebraska Boiler, a Division of Cleaver-Brooks, and Media and Process Technology Inc., and project advisors Georgia Institute of Technology, Alstom Power Inc., Pacific Northwest National Laboratory and Oak Ridge National Laboratory. Phase I of efforts focused on developing 2nd generation boiler concepts and performance modeling; incorporating multi-fuel (natural gas and oil) capabilities; assessing heat recovery, heat transfer and steam superheating approaches; and developing the overall conceptual engineering boiler design. Based on our analysis, the 2nd generation Industrial Watertube Boiler when developed and commercialized, could potentially save 265 trillion Btu and $1.6 billion in fuel costs across U.S. industry through increased efficiency. Its ultra-clean combustion could eliminate 57,000 tons of NOx, 460,000 tons of CO, and 8.8 million tons of CO2 annually from the atmosphere. Reduction in boiler size will bring cost-effective package boilers into a size range previously dominated by more expensive field-erected boilers, benefiting manufacturers and end users through lower capital costs.

Automated CFD Database Generation for a 2nd Generation Glide-Back-Booster  

Science.gov (United States)

A new software tool, AeroDB, is used to compute thousands of Euler and Navier-Stokes solutions for a 2nd generation glide-back booster in one week. The solution process exploits a common job-submission grid environment using 13 computers located at 4 different geographical sites. Process automation and web-based access to the database greatly reduces the user workload, removing much of the tedium and tendency for user input errors. The database consists of forces, moments, and solution files obtained by varying the Mach number, angle of attack, and sideslip angle. The forces and moments compare well with experimental data. Stability derivatives are also computed using a monotone cubic spline procedure. Flow visualization and three-dimensional surface plots are used to interpret and characterize the nature of computed flow fields.

Boosting biogas yield of anaerobic digesters by utilizing concentrated molasses from 2nd generation bioethanol plant  

Energy Technology Data Exchange (ETDEWEB)

Concentrated molasses (C5 molasses) from 2nd generation bioethanol plant has been investigated for enhancing productivity of manure based digesters. A batch study at mesophilic condition (35+- 1 deg C) showed the maximum methane yield from molasses as 286 LCH4/kgVS which was approximately 63% of the calculated theoretical yield. In addition to the batch study, co-digestion of molasses with cattle manure in a semi-continuously stirred reactor at thermophilic temperature (50+- 1 deg C) was also performed with a stepwise increase in molasses concentration. The results from this experiment revealed the maximum average biogas yield of 1.89 L/L/day when 23% VSmolasses was co-digested with cattle manure. However, digesters fed with more than 32% VSmolasses and with short adaptation period resulted in VFA accumulation and reduced methane productivity indicating that when using molasses as biogas booster this level should not be exceeded.

Improved beam spot measurements in the 2nd generation proton beam writing system  

Science.gov (United States)

Nanosized ion beams (especially proton and helium) play a pivotal role in the field of ion beam lithography and ion beam analysis. Proton beam writing has shown lithographic details down to the 20 nm level, limited by the proton beam spot size. Introducing a smaller spot size will allow smaller lithographic features. Smaller probe sizes, will also drastically improve the spatial resolution for ion beam analysis techniques. Among many other requirements, having an ideal resolution standard, used for beam focusing and a reliable focusing method, is an important pre-requisite for sub-10 nm beam spot focusing. In this paper we present the fabrication processes of a free-standing resolution standard with reduced side-wall projection and high side-wall verticality. The resulting grid is orthogonal (90.0° ± 0.1), has smooth edges with better than 6 nm side-wall projection. The new resolution standard has been used in focusing a 2 MeV H2+ beam in the 2nd generation PBW system at Center for Ion Beam Applications, NUS. The beam size has been characterized using on- and off-axis scanning transmission ion microscopy (STIM) and ion induced secondary electron detection, carried out with a newly installed micro channel plate electron detector. The latter has been shown to be a realistic alternative to STIM measurements, as the drawback of PIN diode detector damage is alleviated. With these improvements we show reproducible beam focusing down to 14 nm.

Next generation LP system for maintenance in nuclear power reactors (2nd report)  

International Nuclear Information System (INIS)

Laser peening is a surface enhancement process that introduces compressive residual stress on materials by irradiating laser pulses under aqueous environment. The process utilizes the impulsive effect of high-pressure plasma generated by ablative interaction of each laser pulse. Around a decade ago, the authors invented a new process of laser peening (LP) without any surface preparation, while the conventional types required coating that prevented the surface from melting. Taking advantage of the new process without surface preparation, we have applied laser peening without coating to nuclear power plants as a preventive maintenance against stress corrosion cracking (SCC). Toshiba released the first LP system in 1999, which delivered laser pulses through waterproof pipes with mirrors. In 2002, fiber-delivery was attained and significantly extended the applicability. Now, the development of a new system has been just accomplished, which is extremely simple, reliable and easy-handled. (author)

Street presents enormous risks to street children; they are excluded from safe-family environment, basic services like health and education, and protection against exploitation. This article explored the inclusion of 27 SGSC in regular schools in Accra. Using qualitative methods, we obtained data from 15 teachers and social workers directly involved in the inclusion project. Finding revealed that SGSC were provided with pedagogical materials, daily feeding and school-related needs to encourage school attendance. To enhance positive learning outcomes of SGSC, teachers employed explicit instruction, cooperative learning, and social skills instruction. The study concludes that inclusion of SGSC in regular schools requires a willing and responsible school leadership; a comprehensive needs assessment including street mapping and social investigation on SGSC; financial support; and training of school personnel on streetism.

Strategies for 2nd generation biofuels in EU - Co-firing to stimulate feedstock supply development and process integration to improve energy efficiency and economic competitiveness  

International Nuclear Information System (INIS)

The present biofuel policies in the European Union primarily stimulate 1st generation biofuels that are produced based on conventional food crops. They may be a distraction from lignocellulose based 2nd generation biofuels - and also from biomass use for heat and electricity - by keeping farmers' attention and significant investments focusing on first generation biofuels and the cultivation of conventional food crops as feedstocks. This article presents two strategies that can contribute to the development of 2nd generation biofuels based on lignocellulosic feedstocks. The integration of gasification-based biofuel plants in district heating systems is one option for increasing the energy efficiency and improving the economic competitiveness of such biofuels. Another option, biomass co-firing with coal, generates high-efficiency biomass electricity and reduces CO2 emissions by replacing coal. It also offers a near-term market for lignocellulosic biomass, which can stimulate development of supply systems for biomass also suitable as feedstock for 2nd generation biofuels. Regardless of the long-term priorities of biomass use for energy, the stimulation of lignocellulosic biomass production by development of near term and cost-effective markets is judged to be a no-regrets strategy for Europe. Strategies that induce a relevant development and exploit existing energy infrastructures in order to reduce risk and reach lower costs, are proposed an attractive complement the present and prospective biofuel policies.

Development of WWER-440 fuel. Use of fuel assemblies of 2-nd and 3-rd generations with increased enrichment  

International Nuclear Information System (INIS)

The problem of increasing the power of units at NPPs with WWER-440 is of current importance. There are all the necessary prerequisites for the above-stated problem as a result of updating the design of fuel assemblies and codes. The decrease of power peaking factor in the core is achieved by using profiled fuel assemblies, fuel-integrated burning absorber, FAs with modernized docking unit, modern codes, which allows decreasing conservatism of RP safety substantiation. A wide range of experimental studies of fuel behaviour has been performed which has reached burn-up of (50-60) MW·day/kgU in transition and emergency conditions, post-reactor studies of fuel assemblies, fuel rods and fuel pellets with a 5-year operating period have been performed, which prove high reliability of fuel, presence of a large margin in the fuel pillar, which helps reactor operation at increased power. The results of the work performed on introduction of 5-6 fuel cycles show that the ultimate fuel state on operability in WWER-440 reactors is far from being achieved. Neutron-physical and thermal-hydraulic characteristics of the cores of working power units with RP V-213 are such that actual (design and measured) power peaking factors on fuel assemblies and fuel rods, as a rule, are smaller than the maximum design values. This factor is a real reserve for power forcing. There is experience of operating Units 1, 2, 4 of the Kola NPP and Unit 2 of the Rovno NPP at increased power. Units of the Loviisa NPP are operated at 109 % power. During transfer to work at increased power it is reasonable to use fuel assemblies with increased height of the fuel pillar, which allows decreasing medium linear power distribution. Further development of the 2-nd generation fuel assembly design and consequent transition to working fuel assemblies of the 3-rd generation provides significant improvement of fuel consumption under the conditions of WWER-440 reactors operation with more continuous fuel cycles and increased power

Generative Software Engineering  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Researching evermore abstract and powerful ways of composing programs is the meat of software engineering for half a century. Important early steps were subroutines (to encapsulate actions) and records (to encapsulate data). A large step forward came with the introduction of the object-oriented concepts (classes, subclasses and virtual methods) where classes can encapsulate both data and behaviors in a very powerful, but still flexible, way. For a long time, these concepts dominated the scene...

[Diagnosis of HCV infection by 3rd-generation ELISA in HCV-RNA positive hypertransaminasemic patients with 2nd-generation ELISA negative results].  

Science.gov (United States)

To evaluate the improved sensitivity of 3rd-generation assays for the detection of ani-HCV antibodies in diagnosing cases of HCV infection, we have re-tested by 3rd-generation ELISA test (ELISA-3) serum samples from immunocompetent patients with chronic hypertransaminasemia who were HCV-RNA positive but tested negative with 2nd-generation ELISA (ELISA-2). Out of 21 HCV-RNA positive/ELISA-2 negative samples, 3 (14.3%) were ELISA-3 positive. Among the ELISA-3 reactive samples, two were indeterminate by RIBA-3 (one was reactive with c1 00 and the other with c22), and one was negative. These results demonstrate that even in the clinical setting ELISA-3 improves the diagnosis of HCV infection. The improvement seems to be related to a better reactivity of HCV peptides rather than to the inclusion of the new determinant NS5. However, the sensitivity of the tests for the detection of anti-HCV antibodies remains to be improved. PMID:14976439

Eutectic freeze crystallization in a 2nd generation cooled disk column crystallizer for MgSO 4·H 2O system  

Science.gov (United States)

Eutectic freeze crystallization is a new separation process to produce pure ice and salt from concentrated salt solutions. For this new process, specialized crystallizers are being developed. A new, 2nd generation cooled disc column crystallizer (CDCC-2) with 150-l capacity and 5.6 m 2/m 3 cooling area was designed and tested for MgSO 4 crystallization. A heat flux of 1720-5750 W/m 2 was achieved at a temperature difference between coolant and crystallizer bulk solution of 3-6.5 K and a residence time of 1-3 h. Crystallization and gravitational separation of ice and salt are discussed.

Performance Evaluation of Electrochem's PEM Fuel Cell Power Plant for NASA's 2nd Generation Reusable Launch Vehicle  

Science.gov (United States)

NASA's Next Generation Launch Technology (NGLT) program is being developed to meet national needs for civil and commercial space access with goals of reducing the launch costs, increasing the reliability, and reducing the maintenance and operating costs. To this end, NASA is considering an all- electric capability for NGLT vehicles requiring advanced electrical power generation technology at a nominal 20 kW level with peak power capabilities six times the nominal power. The proton exchange membrane (PEM) fuel cell has been identified as a viable candidate to supply this electrical power; however, several technology aspects need to be assessed. Electrochem, Inc., under contract to NASA, has developed a breadboard power generator to address these technical issues with the goal of maximizing the system reliability while minimizing the cost and system complexity. This breadboard generator operates with dry hydrogen and oxygen gas using eductors to recirculate the gases eliminating gas humidification and blowers from the system. Except for a coolant pump, the system design incorporates passive components allowing the fuel cell to readily follow a duty cycle profile and that may operate at high 6:1 peak power levels for 30 second durations. Performance data of the fuel cell stack along with system performance is presented to highlight the benefits of the fuel cell stack design and system design for NGLT vehicles.

Contribution of ion beam analysis methods to the development of 2nd generation high temperature superconducting (HTS) wires  

Energy Technology Data Exchange (ETDEWEB)

One of the crucial steps in the second generation high temperature superconducting wire program was development of the buffer layer architecture. The architecture designed at the Superconductivity Technology Center at Los Alamos National Laboratory consists of several oxide layers wherein each layer plays a specific role, namely: nucleation layer, diffusion barrier, biaxially textured template, and an intermediate layer with a good match to the lattice parameter of superconducting Y{sub 1}Ba{sub 2}Cu{sub 3}O{sub 7} (YBCO) compound. This report demonstrates how a wide range of ion beam analysis techniques (SIMS, RBS, channeling, PIXE, PIGE, NRA, ERD) was employed for analysis of each buffer layer and the YBCO films. These results assisted in understanding of a variety of physical processes occurring during the buffet layer fabrication and helped to optimize the buffer layer architecture as a whole.

FT-IR Investigation of Hoveyda-Grubbs'2nd Generation Catalyst in Self-Healing Epoxy Mixtures  

International Nuclear Information System (INIS)

The development of smart composites capable of self-repair on aeronautical structures is still at the planning stage owing to complex issues to overcome. A very important issue to solve concerns the components' stability of the proposed composites which are compromised at the cure temperatures necessary for good performance of the composite. In this work we analyzed the possibility to apply Hoveyda Grubbs' second generation catalyst (HG2) to develop self-healing systems. Our experimental results have shown critical issues in the use of epoxy precursors in conjunction with Hoveyda-Grubbs II metathesis catalyst. However, an appropriate curing cycle of the self-healing mixture permits to overcome the critical issues making possible high temperatures for the curing process without deactivating self-repair activity.

The ClearPET(TM) project: development of a 2nd generation high-performance small animal PET scanner  

International Nuclear Information System (INIS)

Second generation high-performance PET scanners, called ClearPET(TM), have been developed by working groups of the Crystal Clear Collaboration (CCC). High sensitivity and high spatial resolution for the ClearPET camera is achieved by using a phoswich arrangement combining two different types of lutetium-based scintillator materials: LSO from CTI and LuYAP:Ce from the CCC (ISTC project). In a first ClearPET prototype, phoswich arrangements of 8x8 crystals of 2x2x10mm3 are coupled to multi-channel photomultiplier tubes (Hamamatsu R7600). A unit of four PMTs arranged in-line represents one of 20 sectors of the ring design. The opening diameter of the ring is 120mm, the axial detector length is 110mm.The PMT pulses are digitized by free-running ADCs and digital data processing determines the gamma energy, the phoswich layer and even the exact pulse starting time, which is subsequently used for coincidence detection. The gantry allows rotation of the detector modules around the field of view.Preliminary data shows a correct identification of the crystal layer about (98±1)%. Typically the energy resolution is (23.3±0.5)% for the luyap layer and (15.4±0.4)% for the lso layer. early studies showed the timing resolution of 2ns FWHM and 4.8ns FWTM. the intrinsic spatial resolution ranges from 1.37mm to 1.61mm full-width of half-maximum (FWHM) with a mean of 1.48mm FWHM. further improvements in image and energy resolution are expected when the system geometry is fully modeled

Power plant intake quantification of wheat straw composition for 2nd generation bioethanol optimization : A Near Infrared Spectroscopy (NIRS) feasibility study  

DEFF Research Database (Denmark)

Optimization of 2nd generation bioethanol production from wheat straw requires comprehensive knowledge of plant intake feedstock composition. Near Infrared Spectroscopy is evaluated as a potential method for instantaneous quantification of the salient fermentation wheat straw components: cellulose (glucan), hemicelluloses (xylan, arabinan), and lignin. Aiming at chemometric multivariate calibration, 44 pre-selected samples were subjected to spectroscopy and reference analysis. For glucan and xylan prediction accuracies (slope: 0.89, 0.94) and precisions (r2: 0.87) were obtained, corresponding to error of prediction levels at 8â??9%. Models for arabinan and lignin were marginally less good, and especially for lignin a further expansion of the feasibility dataset was deemed necessary. The results are related to significant influences from sub-sampling/mass reduction errors in the laboratory regimen. A relative high proportion of outliers excluded from the present models (10â??20%) may indicate that comminution sample preparation is most likely always needed. Different solutions to these issues are suggested.

Early onset hypercholesterolemia induced by the 2nd-generation tyrosine kinase inhibitor nilotinib in patients with chronic phase-chronic myeloid leukemia.  

Science.gov (United States)

Despite a well-recognized clinical benefit of the 2(nd)-generation tyrosine kinase inhibitor nilotinib in patients with imatinib-resistant/-intolerant or newly diagnosed chronic myeloid leukemia, recent evidence suggests that nilotinib has a propensity to increase the risk of occlusive arterial events, especially in patients with pre-existing cardiovascular risk factors. Given the key role of lipids in cardiovascular diseases, we studied the plasma lipid profile and global cardiovascular risk prior to and during nilotinib therapy in a series of 27 patients in the setting of a prospective single center study. Data from a minimum 1-year follow up showed that nilotinib significantly increased total, low- and high-density lipoprotein cholesterol within three months. Consequently, the proportion of patients with non-optimal low-density lipoprotein cholesterol increased from 48.1% to 88.9% by 12 months, leading to cholesterol-lowering drug intervention in 22.2% of patients. The proportion of patients with low levels of high-density lipoprotein cholesterol decreased from 40.7% to 7.4% by 12 months. In contrast, a significant decrease in triglycerides was observed. Global cardiovascular risk worsened in 11.1% of patients due to diabetes or occlusive arterial events. Whether hypercholesterolemia was the main driver of occlusive arterial events was uncertain: a longer follow up is necessary to ask whether nilotinib-induced hypercholesterolemia increases long-term risk of atherosclerotic diseases. Nevertheless, given key atherogenic properties of low-density lipoprotein cholesterol, we conclude that when prescribing nilotinib, commitment to detect lipid disorders at baseline and during follow up is mandatory given their frequency, requirement for changes in lifestyle or drug intervention, and potential for long-term cardiovascular complications.

Experimental and numerical validation of the effective medium theory for the B-term band broadening in 1st and 2nd generation monolithic silica columns.  

Science.gov (United States)

Effective medium theory (EMT) expressions for the B-term band broadening in monolithic silica columns are presented at the whole-column as well as at the mesoporous skeleton level. Given the bi-continuous nature of the monolithic medium, regular as well as inverse formulations of the EMT-expressions have been established. The established expressions were validated by applying them to a set of experimental effective diffusion (Deff)-data obtained via peak parking on a number of 1st and 2nd generation monolithic silica columns, as well as to a set of numerical diffusion simulations in a simplified monolithic column representation (tetrahedral skeleton model) with different external porosities and internal diffusion coefficients. The numerically simulated diffusion data can be very closely represented over a very broad range of zone retention factors (up to k?=80) using the established EMT-expressions, especially when using the inverse variant. The expressions also allow representing the experimentally measured effective diffusion data very closely. The measured Deff/Dmol-values were found to decrease significantly with increasing retention factor, in general going from about Deff/Dmol=0.55 to 0.65 at low k? (k??1.5-3.8) to Deff/Dmol=0.25 at very high k? (k??40-80). These values are significantly larger than observed in fully-porous and core-shell particles. The intra-skeleton diffusion coefficient (Dpz) was typically found to be of the order of Dpz/Dmol=0.4, compared to Dpz/Dmol=0.2-0.35 observed in most particle-based columns. These higher Dpz/Dmol values are the cause of the higher Deff/Dmol values observed. In addition, it also appears that the higher internal diffusion is linked to the higher porosity of the mesoporous skeleton that has a relatively open structure with relatively wide pores. The observed (weak) relation between Dpz/Dmol and the zone retention factor appears to be in good agreement with that predicted when applying the regular variant of the EMT-expression directly to the mesoporous skeleton level.

Test Sequence Generation for Distributed Software System  

Directory of Open Access Journals (Sweden)

Full Text Available This paper considers the test case generation for distributed software (a test case contains one or more test sequences. Applying the single finite state machine (FSM test approach to distributed software, we will suffer from some problems: 1 the state combinatorial explosion problem; 2 some unexecutable test cases may be generated; 3 some fault may be masked and cannot be isolated accurately. This paper proposed a new test case generation method based on the FSM net model. Instead of testing the global transitions of product machine, the generated test cases are used to verify the local transitions. We discuss the detailed methods of verifying the outputs and the tail states of the local transitions. Moreover, we prove that if all the local transitions are right, the transition structure of the distributed software is right. The tests are generated on the local transition structure of components, so we will not meet the state combinatorial explosion problem. All the outputs of the local transitions are checked, so the fault isolation results may be more accurate.

Next-Generation Lightweight Mirror Modeling Software  

Science.gov (United States)

The advances in manufacturing techniques for lightweight mirrors, such as EXELSIS deep core low temperature fusion, Corning's continued improvements in the Frit bonding process and the ability to cast large complex designs, combined with water-jet and conventional diamond machining of glasses and ceramics has created the need for more efficient means of generating finite element models of these structures. Traditional methods of assembling 400,000 + element models can take weeks of effort, severely limiting the range of possible optimization variables. This paper will introduce model generation software developed under NASA sponsorship for the design of both terrestrial and space based mirrors. The software deals with any current mirror manufacturing technique, single substrates, multiple arrays of substrates, as well as the ability to merge submodels into a single large model. The modeler generates both mirror and suspension system elements, suspensions can be created either for each individual petal or the whole mirror. A typical model generation of 250,000 nodes and 450,000 elements only takes 5-10 minutes, much of that time being variable input time. The program can create input decks for ANSYS, ABAQUS and NASTRAN. An archive/retrieval system permits creation of complete trade studies, varying cell size, depth, and petal size, suspension geometry with the ability to recall a particular set of parameters and make small or large changes with ease. The input decks created by the modeler are text files which can be modified by any editor, all the key shell thickness parameters are accessible and comments in deck identify which groups of elements are associated with these parameters. This again makes optimization easier. With ANSYS decks, the nodes representing support attachments are grouped into components; in ABAQUS these are SETS and in NASTRAN as GRIDPOINT SETS, this make integration of these models into large telescope or satellite models possible

Automatic program generation: future of software engineering  

Energy Technology Data Exchange (ETDEWEB)

At this moment software development is still more of an art than an engineering discipline. Each piece of software is lovingly engineered, nurtured, and presented to the world as a tribute to the writer's skill. When will this change. When will the craftsmanship be removed and the programs be turned out like so many automobiles from an assembly line. Sooner or later it will happen: economic necessities will demand it. With the advent of cheap microcomputers and ever more powerful supercomputers doubling capacity, much more software must be produced. The choices are to double the number of programers, double the efficiency of each programer, or find a way to produce the needed software automatically. Producing software automatically is the only logical choice. How will automatic programing come about. Some of the preliminary actions which need to be done and are being done are to encourage programer plagiarism of existing software through public library mechanisms, produce well understood packages such as compiler automatically, develop languages capable of producing software as output, and learn enough about the whole process of programing to be able to automate it. Clearly, the emphasis must not be on efficiency or size, since ever larger and faster hardware is coming.

The 2nd Generation z(Redshift) and Early Universe Spectrometer Part I: First-light observation of a highly lensed local-ULIRG analog at high-z  

CERN Document Server

We report first science results from our new spectrometer, the 2nd generation z(Redshift) and Early Universe Spectrometer (ZEUS-2), recently commissioned on the Atacama Pathfinder Experiment telescope (APEX). ZEUS-2 is a submillimeter grating spectrometer optimized for detecting the faint and broad lines from distant galaxies that are redshifted into the telluric windows from 200 to 850 microns. It utilizes a focal plane array of transition-edge sensed bolometers, the first use of these arrays for astrophysical spectroscopy. ZEUS-2 promises to be an important tool for studying galaxies in the years to come due to its synergy with ALMA and its capabilities in the short submillimeter windows that are unique in the post Herschel era. Here we report on our first detection of the [CII] 158 $\\mu m$ line with ZEUS-2. We detect the line at z ~ 1.8 from H-ATLAS J091043.1-000322 with a line flux of $(6.44 \\pm 0.42) \\times 10^{-18} W m^{-2}$.

Generating Protocol Software from CPN Models Annotated with Pragmatics  

DEFF Research Database (Denmark)

Model-driven software engineering (MDSE) provides a foundation for automatically generating software based on models that focus on the problem domain while abstracting from the details of underlying implementation platforms. Coloured Petri Nets (CPNs) have been widely used to formally model and verify protocol software, but limited work exists on using CPN models of protocols as a basis for automated code generation. The contribution of this paper is a method for generating protocol software from a class of CPN models annotated with code generation pragmatics. Our code generation method consists of three main steps: automatically adding so-called derived pragmatics to the CPN model, computing an abstract template tree, which associates pragmatics with code templates, and applying the templates to generate code which can then be compiled. We illustrate our method using a unidirectional data framing protocol.

Generating regression tests for software migration  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Software modernization projects consist of the redesign of a legacy application and its migration to a novel platform. The validation of the migration step is a major concern since it has to check the exact preservation of the functionalities of the legacy system. Regression testing can be used to perform this validation. However, in most migration projects the specifications and test cases for the legacy application are obsolete. In this context, producing and running the tests can represent...

Computer Software Configuration Item-Specific Flight Software Image Transfer Script Generator  

Science.gov (United States)

A K-shell UNIX script enables the International Space Station (ISS) Flight Control Team (FCT) operators in NASA s Mission Control Center (MCC) in Houston to transfer an entire or partial computer software configuration item (CSCI) from a flight software compact disk (CD) to the onboard Portable Computer System (PCS). The tool is designed to read the content stored on a flight software CD and generate individual CSCI transfer scripts that are capable of transferring the flight software content in a given subdirectory on the CD to the scratch directory on the PCS. The flight control team can then transfer the flight software from the PCS scratch directory to the Electronically Erasable Programmable Read Only Memory (EEPROM) of an ISS Multiplexer/ Demultiplexer (MDM) via the Indirect File Transfer capability. The individual CSCI scripts and the CSCI Specific Flight Software Image Transfer Script Generator (CFITSG), when executed a second time, will remove all components from their original execution. The tool will identify errors in the transfer process and create logs of the transferred software for the purposes of configuration management.

Search-Based Software Test Data Generation Using Evolutionary Computation  

Directory of Open Access Journals (Sweden)

Full Text Available Search-based Software Engineering has been utilized for a number of software engineering activities.One area where Search-Based Software Engineering has seen much application is test data generation. Evolutionary testing designates the use of metaheuristic search methods for test case generation. The search space is the input domain of the test object, with each individual or potential solution, being an encoded set of inputs to that test object. The fitness function is tailored to find test data for the type of testthat is being undertaken. Evolutionary Testing (ET uses optimizing search techniques such as evolutionary algorithms to generate test data. The effectiveness of GA-based testing system is compared with a Random testing system. For simple programs both testing systems work fine, but as the complexity of the program or the complexity of input domain grows, GA-based testing system significantly outperforms Random testing.

Generation of test cases from software requirements using combination trees  

Directory of Open Access Journals (Sweden)

Full Text Available Requirements play an important role in conformance of software quality, which is verified and validated through software testing. Usually the software requirements are expressed natural language such as English. In this paper we present an approach to generate test case from requirements. Our approach takes requirements expressed in natural language and generates test cases using combination trees. However until now we have the tabular representations for combination pairs or simply the charts for them. In this paper we propose the use of combination trees which are far easier to visualize and handle in testing process. This also gives the benefits of remembering the combination of input parameters which we have tested and which are left, giving further confidence on the quality of the product which is to be released.

Model Based Analysis and Test Generation for Flight Software  

Science.gov (United States)

We describe a framework for model-based analysis and test case generation in the context of a heterogeneous model-based development paradigm that uses and combines Math- Works and UML 2.0 models and the associated code generation tools. This paradigm poses novel challenges to analysis and test case generation that, to the best of our knowledge, have not been addressed before. The framework is based on a common intermediate representation for different modeling formalisms and leverages and extends model checking and symbolic execution tools for model analysis and test case generation, respectively. We discuss the application of our framework to software models for a NASA flight mission.

Computer aided power flow software engineering and code generation  

Energy Technology Data Exchange (ETDEWEB)

In this paper a software engineering concept is described which permits the automatic solution of a non-linear set of network equations. The power flow equation set can be seen as a defined subset of a network equation set. The automated solution process is the numerical Newton-Raphson solution process of the power flow equations where the key code parts are the numeric mismatch and the numeric Jacobian term computation. It is shown that both the Jacobian and the mismatch term source code can be automatically generated in a conventional language such as Fortran or C. Thereby one starts from a high level, symbolic language with automatic differentiation and code generation facilities. As a result of this software engineering process an efficient, very high quality Newton-Raphson solution code is generated which allows easier implementation of network equation model enhancements and easier code maintenance as compared to hand-coded Fortran or C code.

Optimized generation of high resolution breast anthropomorphic software phantoms  

International Nuclear Information System (INIS)

Purpose: The authors present an efficient method for generating anthropomorphic software breast phantoms with high spatial resolution. Employing the same region growing principles as in their previous algorithm for breast anatomy simulation, the present method has been optimized for computational complexity to allow for fast generation of the large number of phantoms required in virtual clinical trials of breast imaging. Methods: The new breast anatomy simulation method performs a direct calculation of the Cooper's ligaments (i.e., the borders between simulated adipose compartments). The calculation corresponds to quadratic decision boundaries of a maximum a posteriori classifier. The method is multiscale due to the use of octree-based recursive partitioning of the phantom volume. The method also provides user-control of the thickness of the simulated Cooper's ligaments and skin. Results: Using the proposed method, the authors have generated phantoms with voxel size in the range of (25-1000 ?m)3/voxel. The power regression of the simulation time as a function of the reciprocal voxel size yielded a log-log slope of 1.95 (compared to a slope of 4.53 of our previous region growing algorithm). Conclusions: A new algorithm for computer simulation of breast anatomy has been proposed that allows for fast generation of high resolution anthropomorphic software phantoms.

Fifth-generation computing: dedicated software is the key  

Energy Technology Data Exchange (ETDEWEB)

The nation that controls the manufacture of the best of tomorrow's computers will emerge as the dominant economic power. But, VLSI chips will not determine the best computers. Software, uniquely designed and tailored to an application, will drive the machines that will be made with commodity-like, readily available hardware. Three distinct, but overlapping computer types will dominate the artificial intelligence-based machine that simulates human behavior; the supercomputer geared to high speed number crunching and massive calculations; and the ''standard'' home, factory, or office machine, be it micro, mini, or mainframe. With fine-tuned software, the AI computer will use languages that optimize its symbolic processing and logic manipulations. Meanwhile, the supercomputer will use software geared to its highly parallel architecture, and the ''run-of-the-mill'' machine will feature easy-to-use, portable software that facilitates the networked home, office, and factory.

Generation and Optimization of Test cases for Object-Oriented Software Using State Chart Diagram  

CERN Multimedia

The process of testing any software system is an enormous task which is time consuming and costly. The time and required effort to do sufficient testing grow, as the size and complexity of the software grows, which may cause overrun of the project budget, delay in the development of software system or some test cases may not be covered. During SDLC (software development life cycle), generally the software testing phase takes around 40-70% of the time and cost. State-based testing is frequently used in software testing. Test data generation is one of the key issues in software testing. A properly generated test suite may not only locate the errors in a software system, but also help in reducing the high cost associated with software testing. It is often desired that test data in the form of test sequences within a test suite can be automatically generated to achieve required test coverage. This paper proposes an optimization approach to test data generation for the state-based software testing. In this paper, ...

Adapting software components to be used in a particular application is a crucial issue in software component based technology. In fact, software components can be used in contexts with characteristics different from those envisaged when designing the component. Centralized or distributed deployment infrastructure can be one of these assumptions. Thus, a component can be designed as a monolithic unit to be deployed on a centralized infrastructure, nevertheless the used infrastructure needs the component to be distributed. In this paper, we propose an approach allowing us to transform a centralized software component into a distributed one. Our technique is based on refactoring and fragmentation of component source-code.

[Food intake regulation - 2nd part].  

Science.gov (United States)

The review article summarizes the principles of hedonic regulation of food intake which represents the food intake independent on the maintenance of homeostasis. The theory describing hedonic regulation, so called Incentive Salience Theory, comprises three major processes: liking (positive attribution to food stimulus), wanting (motivation to gain it) and learning (identification of these stimuli and distinguishing them from those connected with aversive reaction). Neuronal reward circuits are the anatomical and functional substrates of hedonic regulation. They react to gustatory and olfactory (or visual) stimuli associated with food intake. A food item is preferred in case its consumption is connected with a pleasant feeling thus promoting the behavioural reaction. The probability of this reaction after repetitive exposure to such a stimulus is increased (learned preference). On the contrary, learned aversion after repetitive exposure is connected with avoidance of a food item associated with a negative feeling. Main mediators of hedonic regulation are endocannabinoids, opioids and monoamines (dopamine, serotonin). Dopamine in dorsal striatum via D2 receptors generates food motivation as a key means of survival, however in ventral striatum (nucleus accumbens) is responsible for motivation to food bringing pleasure. Serotonin via its receptors 5-HT1A a T-HT2C decreases intake of palatable food. It plays a significant role in the pathogenesis of eating disorders, particularly mental anorexia. There, a food restriction represents a kind of automedication to constitutionally pathologically increased serotonin levels. Detailed understanding of processes regulating food intake is a key to new pharmacological interventions in eating disorders. PMID:24564775

FACTORS GENERATING RISKS DURING REQUIREMENT ENGINEERING PROCESS IN GLOBAL SOFTWARE DEVELOPMENT ENVIRONMENT  

Directory of Open Access Journals (Sweden)

Full Text Available Challenges of Requirements Engineering become adequate when it is performed in global software development paradigm. There can be many reasons behind this challenging nature. “Risks” can be one of them, as there is more risk exposure in global development paradigm. So it is may be one of the main reasons of making Requirement Engineering more challenging. For this first there is a need to identify the factors which actually generate these risks. This paper therefore not only identifies the factors, but also the risks which these factors may generate. A systematic literature review is done for the identification of these factors and the risks which may occur during requirement engineering process in global software development paradigm. The list leads to progressive enhancement for assisting in requirement engineering activities in global software development paradigm. This work is especially useful for the, less experience people working in global software development.

Automatic test case generation for safety-critical software reliability demonstration  

International Nuclear Information System (INIS)

CANDU generating stations incorporate special safety systems, whose function is to detect the presence of adverse plant conditions and, under these conditions, initiate a reactor shutdown, containment and emergency cooling. Recently, the design of these systems has incorporated software components. As a result of the high integrity requirements placed on the overall systems, the software components are safety-critical. One aspect of the software's integrity is its reliability. The Canadian nuclear industry has a standard to which safety-critical software is engineered. Associated with this standard is a procedure for testing the software to demonstrate statistically its reliability. This paper focuses on a Computer Aided Software Testing (CAST) tool that supports this procedure by allowing safety engineers to configure directly the automatic generation of test cases using high-level concepts from nuclear operating experience and safety analysis data. We describe the design of the tool and give an example of how it has been used on a recent software development project. (author) 22 refs., 2 figs

A computer-based physics laboratory apparatus: Signal generator software  

Science.gov (United States)

This paper describes a computer-based physics laboratory apparatus to replace expensive instruments such as high-precision signal generators. This apparatus uses a sound card in a common personal computer to give sinusoidal signals with an accurate frequency that can be programmed to give different frequency signals repeatedly. An experiment on standing waves on an oscillating string uses this apparatus. In conjunction with interactive lab manuals, which have been developed using personal computers in our university, we achieve a complete set of low-cost, accurate, and easy-to-use equipment for teaching a physics laboratory.

THR Simulator – the software for generating radiographs of THR prosthesis  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Measuring the orientation of acetabular cup after total hip arthroplasty is important for prognosis. The verification of these measurement methods will be easier and more feasible if we can synthesize prosthesis radiographs in each simulated condition. One reported method used an expensive mechanical device with an indeterminable precision. We thus develop a program, THR Simulator, to directly synthesize digital radiographs of prostheses for further analysis. Under Windows platform and using Borland C++ Builder programming tool, we developed the THR Simulator. We first built a mathematical model of acetabulum and femoral head. The data of the real dimension of prosthesis was adopted to generate the radiograph of hip prosthesis. Then with the ray tracing algorithm, we calculated the thickness each X-ray beam passed, and then transformed to grey scale by mapping function which was derived by fitting the exponential function from the phantom image. Finally we could generate a simulated radiograph for further analysis. Results Using THR Simulator, the users can incorporate many parameters together for radiograph synthesis. These parameters include thickness, film size, tube distance, film distance, anteversion, abduction, upper wear, medial wear, and posterior wear. These parameters are adequate for any radiographic measurement research. This THR Simulator has been used in two studies, and the errors are within 2° for anteversion and 0.2 mm for wearing measurement. Conclusion We design a program, THR Simulator that can synthesize prosthesis radiographs. Such a program can be applied in future studies for further analysis and validation of measurement of various parameters of pelvis after total hip arthroplasty.

Mapping and industrial IT project to a 2nd semester design-build project  

DEFF Research Database (Denmark)

CDIO means bringing the engineer's daily life and working practice into the educational system. In our opinion this is best done by selecting an appropriate project from industry. In this paper we describe how we have mapped an industrial IT project to a 2nd semester design-build project in the Diploma IT program at the Technical University of Denmark. The system in question is a weighing system operating in a LAN environment. The system is used in the medical industry for producing tablets. We present the design of a curriculum to support the development of major components of the weighing system. A simple teaching model for software engineering is presented which combines technical disciplines with disciplines from section 2-4 in the CDIO syllabus. The implementation of a joint project involving several courses supports the CDIO perspective. Already the traditional IT-diploma education for decades has included many of the essential features of the CDIO (for example, focus on teamwork, development of social skills, the open nature of design problems). The specific project has previously been conducted on 5th Semester The project has now been brought forward to the 2nd semester of study. A successful implementation at this level requires careful planning of activities through the semester. Principles of the CDIO have been of great help in this regard. Finally we draw conclusions and give our recommendations based on those.

Advanced User Interface Generation in the Software Framework for Magnetic Measurements at CERN  

CERN Multimedia

A model-based approach, the Model-View-Interactor Paradigm, for automatic generation of user interfaces in software frameworks for measurement systems is proposed. The Model-View-Interactor Paradigm is focused on the ``interaction{''} typical in a software framework for measurement applications: the final user interacts with the automatic measurement system executing a suitable high-level script previously written by a test engineer. According to the main design goal of frameworks, the proposed approach allows the user interfaces to be separated easily from the application logic for enhancing the flexibility and reusability of the software. As a practical case study, this approach has been applied to the flexible software framework for magnetic measurements at the European Organization for Nuclear research (CERN). In particular, experimental results about the scenario of permeability measurements are reported.

Reliable Mining of Automatically Generated Test Cases from Software Requirements Specification (SRS)  

CERN Document Server

Writing requirements is a two-way process. In this paper we use to classify Functional Requirements (FR) and Non Functional Requirements (NFR) statements from Software Requirements Specification (SRS) documents. This is systematically transformed into state charts considering all relevant information. The current paper outlines how test cases can be automatically generated from these state charts. The application of the states yields the different test cases as solutions to a planning problem. The test cases can be used for automated or manual software testing on system level. And also the paper presents a method for reduction of test suite by using mining methods thereby facilitating the mining and knowledge extraction from test cases.

Ontology-based Software for Generating Scenarios for Characterizing Searches for Nuclear Materials  

Energy Technology Data Exchange (ETDEWEB)

A software environment was created in which ontologies are used to significantly expand the number and variety of scenarios for special nuclear materials (SNM) detection based on a set of simple generalized initial descriptions. A framework was built that combined advanced reasoning from ontologies with geographical and other data sources to generate a much larger list of specific detailed descriptions from a simple initial set of user-input variables. This presentation shows how basing the scenario generation on a process of inferencing from multiple ontologies, including a new SNM Detection Ontology (DO) combined with data extraction from geodatabases, provided the desired significant variability of scenarios for testing search algorithms, including unique combinations of variables not previously expected. The various components of the software environment and the resulting scenarios generated will be discussed.

2nd Medicon Valley Inhalation Symposium 16 October 2013, Lund, Sweden The 2nd Medicon Valley Inhalation Symposium was arranged by the Medicon Valley Inhalation Consortium. It was held at the Medicon Village, which is the former AstraZeneca site in Lund, Sweden. It was a 1 day symposium focused on inhaled drug delivery and inhalation product development. 120 delegates listened to 11 speakers. The program was organized to follow the value chain of an inhalation product development. This year there was a focus on inhaled biomolecules. The inhaled delivery of insulin was covered by two presentations and a panel discussion. The future of inhaled drug delivery was discussed together with an overview of the current market situation. Two of the inhalation platforms, capsule inhalers and metered-dose inhalers, were discussed in terms of the present situation and the future opportunities. Much focus was on the regulatory and intellectual aspects of developing inhalation products. The manufacturing of a dry powder inhaler requires precision filling of powder, and the various techniques were presented. The benefits of nebulization and nasal delivery were illustrated with some case studies and examples. The eternal challenge of poor compliance was addressed from an industrial design perspective and some new approaches were introduced. PMID:24483190

Software for Generating Troposphere Corrections for InSAR Using GPS and Weather Model Data  

Science.gov (United States)

Atmospheric errors due to the troposphere are a limiting error source for spaceborne interferometric synthetic aperture radar (InSAR) imaging. This software generates tropospheric delay maps that can be used to correct atmospheric artifacts in InSAR data. The software automatically acquires all needed GPS (Global Positioning System), weather, and Digital Elevation Map data, and generates a tropospheric correction map using a novel algorithm for combining GPS and weather information while accounting for terrain. Existing JPL software was prototypical in nature, required a MATLAB license, required additional steps to acquire and ingest needed GPS and weather data, and did not account for topography in interpolation. Previous software did not achieve a level of automation suitable for integration in a Web portal. This software overcomes these issues. GPS estimates of tropospheric delay are a source of corrections that can be used to form correction maps to be applied to InSAR data, but the spacing of GPS stations is insufficient to remove short-wavelength tropospheric artifacts. This software combines interpolated GPS delay with weather model precipitable water vapor (PWV) and a digital elevation model to account for terrain, increasing the spatial resolution of the tropospheric correction maps and thus removing short wavelength tropospheric artifacts to a greater extent. It will be integrated into a Web portal request system, allowing use in a future L-band SAR Earth radar mission data system. This will be a significant contribution to its technology readiness, building on existing investments in in situ space geodetic networks, and improving timeliness, quality, and science value of the collected data

Scoping analysis of the Advanced Test Reactor using SN2ND  

Energy Technology Data Exchange (ETDEWEB)

A detailed set of calculations was carried out for the Advanced Test Reactor (ATR) using the SN2ND solver of the UNIC code which is part of the SHARP multi-physics code being developed under the Nuclear Energy Advanced Modeling and Simulation (NEAMS) program in DOE-NE. The primary motivation of this work is to assess whether high fidelity deterministic transport codes can tackle coupled dynamics simulations of the ATR. The successful use of such codes in a coupled dynamics simulation can impact what experiments are performed and what power levels are permitted during those experiments at the ATR. The advantages of the SN2ND solver over comparable neutronics tools are its superior parallel performance and demonstrated accuracy on large scale homogeneous and heterogeneous reactor geometries. However, it should be noted that virtually no effort from this project was spent constructing a proper cross section generation methodology for the ATR usable in the SN2ND solver. While attempts were made to use cross section data derived from SCALE, the minimal number of compositional cross section sets were generated to be consistent with the reference Monte Carlo input specification. The accuracy of any deterministic transport solver is impacted by such an approach and clearly it causes substantial errors in this work. The reasoning behind this decision is justified given the overall funding dedicated to the task (two months) and the real focus of the work: can modern deterministic tools actually treat complex facilities like the ATR with heterogeneous geometry modeling. SN2ND has been demonstrated to solve problems with upwards of one trillion degrees of freedom which translates to tens of millions of finite elements, hundreds of angles, and hundreds of energy groups, resulting in a very high-fidelity model of the system unachievable by most deterministic transport codes today. A space-angle convergence study was conducted to determine the meshing and angular cubature requirements for the ATR, and also to demonstrate the feasibility of performing this analysis with a deterministic transport code capable of modeling heterogeneous geometries. The work performed indicates that a minimum of 260,000 linear finite elements combined with a L3T11 cubature (96 angles on the sphere) is required for both eigenvalue and flux convergence of the ATR. A critical finding was that the fuel meat and water channels must each be meshed with at least 3 'radial zones' for accurate flux convergence. A small number of 3D calculations were also performed to show axial mesh and eigenvalue convergence for a full core problem. Finally, a brief analysis was performed with different cross sections sets generated from DRAGON and SCALE, and the findings show that more effort will be required to improve the multigroup cross section generation process. The total number of degrees of freedom for a converged 27 group, 2D ATR problem is {approx}340 million. This number increases to {approx}25 billion for a 3D ATR problem. This scoping study shows that both 2D and 3D calculations are well within the capabilities of the current SN2ND solver, given the availability of a large-scale computing center such as BlueGene/P. However, dynamics calculations are not realistic without the implementation of improvements in the solver.

Software architecture for control and data acquisition of linear plasma generator Magnum-PSI  

Energy Technology Data Exchange (ETDEWEB)

Highlights: ? An architecture based on a modular design. ? The design offers flexibility and extendability. ? The design covers the overall software architecture. ? It also covers its (sub)systems’ internal structure. -- Abstract: The FOM Institute DIFFER – Dutch Institute for Fundamental Energy Research has completed the construction phase of Magnum-PSI, a magnetized, steady-state, large area, high-flux linear plasma beam generator to study plasma surface interactions under ITER divertor conditions. Magnum-PSI consists of several hardware subsystems, and a variety of diagnostic systems. The COntrol, Data Acquisition and Communication (CODAC) system integrates these subsystems and provides a complete interface for the Magnum-PSI users. Integrating it all, from the lowest hardware level of sensors and actuators, via the level of networked PLCs and computer systems, up to functions and classes in programming languages, demands a sound and modular software architecture, which is extendable and scalable for future changes. This paper describes this architecture, and the modular design of the software subsystems. The design is implemented in the CODAC system at the level of services and subsystems (the overall software architecture), as well as internally in the software subsystems.

SEMANTIC WEB-BASED SOFTWARE ENGINEERING BY AUTOMATED REQUIREMENTS ONTOLOGY GENERATION IN SOA  

Directory of Open Access Journals (Sweden)

Full Text Available This paper presents an approach for automated generation of requirements ontology using UML diagrams in service-oriented architecture (SOA. The goal of this paper is to convenience progress of software engineering processes like software design, software reuse, service discovering and etc. The proposed method is based on a four conceptual layers. The first layer includes requirements achieved by stakeholders, the second one designs service-oriented diagrams from the data in first layer and extracts XMI codes of them. The third layer includes requirement ontology and protocol ontology to describe behavior of services and relationships between them semantically. Finally the forth layer makes standard the concepts exists in ontologies of previous layer. The generated ontology exceeds absolute domain ontology because it considers the behavior of services moreover the hierarchical relationship of them. Experimental results conducted on a set of UML4Soa diagrams in different scopes demonstrate the improvement of the proposed approach from different points of view such as: completeness of requirements ontology, automatic generation and considering SOA.

Reliable Mining of Automatically Generated Test Cases from Software Requirements Specification (SRS  

Directory of Open Access Journals (Sweden)

Full Text Available Writing requirements is a two-way process. In this paper we use to classify Functional Requirements (FR and Non Functional Requirements (NFR statements from Software Requirements Specification (SRS documents. This is systematically transformed into state charts considering all relevant information. The current paper outlines how test cases can be automatically generated from these state charts. The application of the states yields the different test cases as solutions to a planning problem. The test cases can be used for automated or manual software testing on system level. And also the paper presents a method for reduction of test suite by using mining methods thereby facilitating the mining and knowledge extraction from test cases.

Improvement of a plasma uniformity of the 2nd ion source of KSTAR neutral beam injector  

International Nuclear Information System (INIS)

The 2nd ion source of KSTAR (Korea Superconducting Tokamak Advanced Research) NBI (Neutral Beam Injector) had been developed and operated since last year. A calorimetric analysis revealed that the heat load of the back plate of the ion source is relatively higher than that of the 1st ion source of KSTAR NBI. The spatial plasma uniformity of the ion source is not good. Therefore, we intended to identify factors affecting the uniformity of a plasma density and improve it. We estimated the effects of a direction of filament current and a magnetic field configuration of the plasma generator on the plasma uniformity. We also verified that the operation conditions of an ion source could change a uniformity of the plasma density of an ion source

RAVE: First results and 2nd data release  

Science.gov (United States)

RAVE, the RAdial Velocity Experiment, is an ambitious program to conduct a survey to measure the radial velocities, metallicities and abundance ratios for up to a million stars using the 1.2-m UK Schmidt Telescope of the Anglo-Australian Observatory (AAO), over the period 2003-2010. The survey represents a giant leap forward in our understanding of our own Milky Way galaxy, providing a vast stellar kinematic database larger than any other survey proposed for this coming decade. The main data product will be a southern hemisphere survey of about a million stars. This survey would comprise 0.7 million thin disk main sequence stars, 250 000 thick disk stars, 100 000 bulge and halo stars, and a further 50 000 giant stars including some out to 10 kpc from the Sun. RAVE will offer the first truly representative inventory of stellar radial velocities for all major components of the Galaxy. Here we present the first scientific results of this survey as well as its second data release which doubles the number of previously released radial velocities. For the first time, the release also provides atmospheric parameters for a large fraction of the 2nd year data making it an unprecedented tool to study the formation of the Milky Way.

Book review: Psychology in a work context (2nd Ed.  

Directory of Open Access Journals (Sweden)

Full Text Available Bergh, Z. & Theron, A.L. (Eds (2003 Psychology in a work context (2nd Ed.. Cape Town: Oxford University Press.

This book is an overview and introduction to Industrial and Organisational Psychology. It is a work of ambitious scope, and it is clear that the contributors have invested a great deal of thought and effort in the planning and execution of the book. The current version is the second edition, and it looks set to become one of those standard textbooks that are revised every few years to keep up with changing times. It is a handsome volume, produced to a high standard of editorial care, pleasingly laid out and organised well enough to be useful as an occasional reference source. An English-Afrikaans glossary, tables of contents for every chapter as well as for the entire book, a comprehensive index and extensive bibliography make it easy to retrieve the information relating to a particular topic. Every chapter ends with a conclusion summarising the gist of the material covered. Quality illustrations lighten the tone and help to bring some of the concepts to life. Learning outcomes and self-assessment exercises and questions for every chapter will be useful to the lecturer using the book as a source for a tutored course, and for the student studying by distance learning. If sold at the suggested retail price, the book represents good value compared to imported textbooks that cover similar ground.

Aptaligner: automated software for aligning pseudorandom DNA x-aptamers from next-generation sequencing data.  

Science.gov (United States)

Next-generation sequencing results from bead-based aptamer libraries have demonstrated that traditional DNA/RNA alignment software is insufficient. This is particularly true for X-aptamers containing specialty bases (W, X, Y, Z, ...) that are identified by special encoding. Thus, we sought an automated program that uses the inherent design scheme of bead-based X-aptamers to create a hypothetical reference library and Markov modeling techniques to provide improved alignments. Aptaligner provides this feature as well as length error and noise level cutoff features, is parallelized to run on multiple central processing units (cores), and sorts sequences from a single chip into projects and subprojects.

On the 2nd order autocorrelation of an XUV attosecond pulse train  

International Nuclear Information System (INIS)

Full text: We present the first direct measurement of sub-fs light bunching that has been achieved, extending well established fs optical metrology to XUV as pulses. A mean train pulse duration of 780 as has been extracted through a 2nd order autocorrelation approach, utilizing a nonlinear effect that is induced solely by the XUV radiation to be characterized. The approach is based on (i) a bisected spherical mirror XUV wavefront divider used as an autocorrelator and (ii) the two photon ionization of atomic He by a superposition of the 7th to the 15th harmonic of a Ti:sapph laser. The measured temporal mean width is more than twice its Fourier transform limited (FTL) value, in contrast to the as train pulse durations measured through other approaches, which where found much closer to the FTL values. We have investigated, and discuss here the origin of this discrepancy. An assessment of the validity of the 2nd order AC approach for the broad band XUV radiation of as pulses is implemented through ab initio calculations (solution of the 3D TDSE of He in the presence of the superposition of the harmonic superposition) modeling the spectral and temporal response of the two-XUV-photon He ionization detector employed. It is found that both the spectral and temporal response are not affecting the measured duration. The mean width of the as train bursts is estimated from the spectral phases of the individual harmonics as they result from the rescattering model, taking into account the spatially modulated temporal width of the radiation due to the spatiotemporal intensity distribution of the driving field during the harmonic generation process. The measured value is found in reasonable agreement with the estimated duration. The method used for the 2nd order AC in itself initiates further XUV-pump-XUV-probe studies of sub-fs-scale dynamics and at the same time becomes highly pertinent in connection with nonlinear experiments using XUV free - electron laser sources.

NEXT GENERATION ANALYSIS SOFTWARE FOR COMPONENT EVALUATION - Results of Rotational Seismometer Evaluation  

Science.gov (United States)

The Component Evaluation project at Sandia National Laboratories supports the Ground-based Nuclear Explosion Monitoring program by performing testing and evaluation of the components that are used in seismic and infrasound monitoring systems. In order to perform this work, Component Evaluation maintains a testing facility called the FACT (Facility for Acceptance, Calibration, and Testing) site, a variety of test bed equipment, and a suite of software tools for analyzing test data. Recently, Component Evaluation has successfully integrated several improvements to its software analysis tools and test bed equipment that have substantially improved our ability to test and evaluate components. The software tool that is used to analyze test data is called TALENT: Test and AnaLysis EvaluatioN Tool. TALENT is designed to be a single, standard interface to all test configuration, metadata, parameters, waveforms, and results that are generated in the course of testing monitoring systems. It provides traceability by capturing everything about a test in a relational database that is required to reproduce the results of that test. TALENT provides a simple, yet powerful, user interface to quickly acquire, process, and analyze waveform test data. The software tool has also been expanded recently to handle sensors whose output is proportional to rotation angle, or rotation rate. As an example of this new processing capability, we show results from testing the new ATA ARS-16 rotational seismometer. The test data was collected at the USGS ASL. Four datasets were processed: 1) 1 Hz with increasing amplitude, 2) 4 Hz with increasing amplitude, 3) 16 Hz with increasing amplitude and 4) twenty-six discrete frequencies between 0.353 Hz to 64 Hz. The results are compared to manufacture-supplied data sheets.

Energies of the 1s2nd Rydberg states for the lithium atom  

International Nuclear Information System (INIS)

In this work, energy levels and quantum defects of 1s2nd bound states and their adjacent continuum states for the lithium atom are calculated with the R-matrix theory, and then the quantum defect function of the 1s2nd channel is obtained, which vary smoothly with the energy based on the quantum defect theory. The obtained quantum defect function is calibrated from more accurate experimental value of higher Rydberg state and used to calculate quantum defects, ionization potentials and transition energies (relative to the 1s22s ground state) of 1s2nd high Rydberg states of the lithium atom. Present calculations may help in performing measurements of yet unmeasured 1s2nd Rydberg states of this system in future. -- Highlights: •Quantum defects of 1s2nd channel for the lithium atom are calculated. •The QDF of the 1s2nd channel is obtained by the quantum defect theory. •The original QDF is calibrated from more accurate experimental value. •The new QDF is used to calculate term energies of the 1s2nd Rydberg states. •Present calculations help in performing measurements of 1s2nd Rydberg states

The rank of the 2nd Gaussian map for general curves  

CERN Multimedia

We prove that, for the general curve of genus g, the 2nd Gaussian map is injective if g = 18. The proof relies on the study of the limit of the 2nd Gaussian map when the general curve of genus g degenerates to a general stable binary curve, i.e. the union of two rational curves meeting at g+1 points.

A software tool for simulation of surfaces generated by ball nose end milling  

DEFF Research Database (Denmark)

The number of models available for prediction of surface topography is very limited. The main reason is that these models cannot be based on engineering principles like those for elastic deformations. Most knowledge about surface roughness and integrity is empirical and up to now very few mathematical relationships relating surface parameters to cutting conditions are available. Basic models of kinematical roughness, determined by the tool profile and the pattern of relative motions of tool and workpiece, have been so far not reliable. The actual roughness may be more than five times higher due to error motions, unstable built up edge and changing tool profile due to wear [1]. Tool chatter is also affecting surface roughness, but its effect is normally not included in prediction of surface roughness, since machining conditions which generate chatter must be avoided in any case. Finally, reproducibility of experimental results concerning surface roughness requires tight control of all influencing factors, difficult to keep in actual machining workshops. This introduces further complications in surface topography modelling. In the light of these considerations, a simple software tool, for prediction of surface topography of ball nose end milled surfaces, was developed. Such software tool is based on a simplified model of the ideal tool motion and neglects the effects due to run-out, static and dynamic deflections and error motions, but has the merit of generating in output a file in a format readable by a surface processor software (SPIP [2]), for calculation of a number of surface roughness parameters. In the next paragraph a description of the basic features of ball nose end milled surfaces is given, while in paragraph 3 the model is described.

Dr. Janet Bohren from University of Cincinnati and Jennifer McVay-Dyche from United Theological Seminary, explained their experience with a course management system used to develop dialogue between K-12 teachers in Turkey and the US, on the topics of religion, culture and schools. Their workshop provided an overview of a pilot study. They showed us a good case-study of utilizing “Blackboard” as a mean for getting rid of biases and improving the understanding of the American and Turkish teachers against each other. We had very remarkable key notes as well. Dr Nikitas Kastis representing European Distance and E-Learning Network (EDEN made his speech on distance and e-Learning evolutions and trends in Europe. He informed the audience about the application and assessment criteria at European scale, concerning e-Learning in the education and training systems. Meanwhile, our key note speakers took our attention to different applications of virtual learning. Dr. Piet Kommers from University of Twente exemplified a virtual training environment for acquiring surgical skills. Dr. Timothy Shih from Tamkang University presented their project called Hard SCORM (Sharable Content Object Reference Model as an asynchronous distance learning specification. In his speech titled “Engaging and Supporting Problem Solving Online” Prof. David Jonassen from University of Missouri, reflected his vision of the future of education and explained why it should embrace problem solving. Then he showed us examples of incorporating this vision with learning environments for making online problem solving possible. Dr. Wolfram Laaser from Fern University talked on applications of ICT at Europe

Computer software program for monitoring the availability of systems and components of electric power generating systems  

International Nuclear Information System (INIS)

As availabilities of electric power generating stations systems and components become more and more important from a financial, personnel safety, and regulatory requirements standpoint, it is evident that a comprehensive, yet simple and user-friendly program for system and component tracking and monitoring is needed to assist in effectively managing the large volume of systems and components with their large numbers of associated maintenance/availability records. A user-friendly computer software program for system and component availability monitoring has been developed that calculates, displays and monitors selected component and system availabilities. This is a Windows trademark based (Graphical User Interface) program that utilizes a system flow diagram for the data input screen which also provides a visual representation of availability values and limits for the individual components and associated systems. This program can be customized to the user's plant-specific system and component selections and configurations. As will be discussed herein, this software program is well suited for availability monitoring and ultimately providing valuable information for improving plant performance and reducing operating costs

Software for evaluating magnetic induction field generated by power lines: implementation of a new algorithm  

International Nuclear Information System (INIS)

The Regional Environment Protection Agency of Friuli Venezia Giulia (A.R.P.A. F.V.G., Italy) has performed an analysis on existing software designed to calculate magnetic induction field generated by power lines. As far as the agency requirements are concerned the tested programs display some difficulties in the immediate processing of electrical and geometrical data supplied by plant owners, and in certain cases turn out to be inadequate in representing complex configurations of power lines. Furthermore, none of them is preset for cyclic calculus to determine the time evolution of induction in a certain exposure area. Finally, the output data are not immediately importable by ArcView, the G.I.S. used by A.R.P.A. F.V.G., and it is not always possible to implement the territory orography to determine the field at specified heights above the ground. P.h.i.d.e.l., an innovative software, tackles and works out al l the above mentioned problems. The power line wires interested in its implementation are represented by poly lines, and the field is analytically calculated, with no further approximation, not even when more power lines are concerned. Therefore, the obtained results, when compared with those of other programs, are the closest to experimental measurements. The output data can be employed both in G.I.S. and Excel environments, allowing the immediate overlaying of digital cartography and the determining of the 3 and 10 ?T bands, in compliance with the Italian Decree of the President of the Council of Ministers of 8 July 2003.

Managing Complexity in Next Generation Robotic Spacecraft: From a Software Perspective  

Science.gov (United States)

This presentation highlights the challenges in the design of software to support robotic spacecraft. Robotic spacecraft offer a higher degree of autonomy, however currently more capabilities are required, primarily in the software, while providing the same or higher degree of reliability. The complexity of designing such an autonomous system is great, particularly while attempting to address the needs for increased capabilities and high reliability without increased needs for time or money. The efforts to develop programming models for the new hardware and the integration of software architecture are highlighted.

Study on SOFC combined cycle power generation system. 2nd Report. Study of influence of system configuration on performance of SOFC power plants; Kotai denkaishitsugata nenryo denchi fukugo hatsuden system no kenkyu. 2. Kosei ga kotonaru hatsuden system no seino kaisek  

Energy Technology Data Exchange (ETDEWEB)

System analysis of Solid Oxide Fuel Cell (SOFC)/Gas Turbine (GT) combined cycle power generation systems were carried out by means of numerical simulation method. In the first report, the influence of the SOFC operation conditions on the efficiencies of the system was discussed. This report studied the influence of the system configuration on the system performance. First, the system performance using internal reforming was compared with that using external reforming. Next, the system performance using cathode gas recycling or anode gas recycling was studied. As a result, it was clarified that the use of the internal reforming or gas recycling was effective to raise the gas turbine inlet temperature, but did not always make the system efficiency improvements. However, when the Heat Recovery Steam Generator is installed in the system using anode gas recycling, the efficiency of the SOFC/GT/Steam Turbine combined cycle power generation system was estimated to be over 65%.

2nd Topical Workshop on Laser Technology and Optics Design  

CERN Document Server

Lasers have a variety of applications in particle accelerator operation and will play a key role in the development of future particle accelerators by improving the generation of high brightness electron and exotic ion beams and through increasing the acceleration gradient. Lasers will also make an increasingly important contribution to the characterization of many complex particle beams by means of laser-based beam diagnostics methods. The second LANET topical workshop will address the key aspects of laser technology and optics design relevant to laser application to accelerators. The workshop will cover general optics design, provide an overview of different laser sources and discuss methods to characterize beams in details. Participants will be able to choose from a range of topical areas that go deeper in more specific aspects including tuneable lasers, design of transfer lines, noise sources and their elimination and non-linear optics effects. The format of the workshop will be mainly training-based wit...

From next-generation sequencing alignments to accurate comparison and validation of single-nucleotide variants: the pibase software  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Scientists working with single-nucleotide variants (SNVs), inferred by next-generation sequencing software, often need further information regarding true variants, artifacts and sequence coverage gaps. In clinical diagnostics, e. g. SNVs must usually be validated by visual inspection or several independent SNV-callers. We here demonstrate that 0.5-60% of relevant SNVs might not be detected due to coverage gaps, or might be misidentified. Even low error rates can overwhelm the true biological ...

OASIS4 – a coupling software for next generation earth system modelling  

Directory of Open Access Journals (Sweden)

Full Text Available In this article we present a new version of the Ocean Atmosphere Sea Ice Soil coupling software (OASIS4. With this new fully parallel OASIS4 coupler we target the needs of Earth system modelling in its full complexity. The primary focus of this article is to describe the design of the OASIS4 software and how the coupling software drives the whole coupled model system ensuring the synchronization of the different component models. The application programmer interface (API manages the coupling exchanges between arbitrary climate component models, as well as the input and output from and to files of each individual component. The OASIS4 Transformer instance performs the parallel interpolation and transfer of the coupling data between source and target model components. As a new core technology for the software, the fully parallel search algorithm of OASIS4 is described in detail. First benchmark results are discussed with simple test configurations to demonstrate the efficiency and scalability of the software when applied to Earth system model components. Typically the compute time needed to perform the search is in the order of a few seconds and is only weakly dependant on the grid size.

Highlights of the 2nd session of the General Conference  

International Nuclear Information System (INIS)

The debates of the Conference were based on the 'First Annual Report to the General Conference' (GC(n)/39) covering the period 23 October 1957 to 30 June 1958, the 'Programme and Budget for 1959' (GC(H)/36) both submitted by the Board of Governors and on the statement made by the Director General on 22 September 1958 (GC(II)OR. 14) which brought the survey of the Agency's activities up-to-date. Delegates appraised the first year's achievements and many speakers emphasized the importance of close international co-operation in the field of atomic energy and dealt with the role the IAEA was called upon to play. Referring to the offers of various and in particular fissionable materials several delegates supported the statement made by the Director General in his opening address that some preferential treatment must be given the Agency by the offering countries thereby providing some inducement for governments to utilize the channels of true international co-operation. Issues concerning safeguards and reactors were discussed. The Conference finally recommended that the Board of Governors should give earnest and early consideration to initiating action for a survey to be made of the needs of the less developed countries in the matter of nuclear power generation plants, and to the adoption of measures for continuing study regarding the development of technology and economics of small and medium scale nuclear power reactors best suited for less developed countries, and assisting them in planning and implementing their training programmes in that connection. The Conference, finally, voted in favour of the appropriations necessary for the setting up of laboratory facilities. Practically all delegates agreed, although with varying emphasis, on the importance of technical assistance and other activities of the IAEA which would soonest benefit the less advanced countries. The General Conference finally approved by 59 votes, none against and one abstention the Board of Governors' recommendation that the total appropriation for the administrative expenses of the Agency in 1959 shall amount to $5,225,000, and by 58 votes, none against and one abstention that the target for voluntary contributions to the General Fund be set at $1,500,000. A number of separate votes on individual budget items had all resulted in majorities for the original Board of Governors' recommendations. A Special Committee on, the pledging of voluntary contributions to the General Fund from which the operational part of the Agency's programme was to be financed met on 3 October. As Mr. Sterling Cole, Director General, explained unlike the specialized agencies of the UN, the Agency's technical assistance activities, including all fellowships and technical assistance projects and equipment provided at the Agency's expense as well as its functional laboratory will have to be financed at present through voluntary contributions. By the end of the second session of the General Conference, the President was able to announce a total of approximately $ 848,000 pledged by 21 Member States, a number of delegates having indicated their countries' willingness to make contributions, the amount of which would be made known at a later date. All main decisions taken during the second session of the General Conference are listed

Generation of controller of an underwater robot for constant altitude cruising by self-training. 2nd Report. ; Modification of forward model and adaptation process. Jiko kunren ni yoru kaichu robot no teikodo koko. 2. ; Forward model to controller no chosei hoho no kairyo  

Energy Technology Data Exchange (ETDEWEB)

As a guidance system to be applied to constant altitude cruising of the self-controlling underwater robot, improvement of the SONCS (composed from controller network and forward model network) proposed in the previous paper by the author's laboratory is reported. The forward model network was divided into three modules respectively holding a function representing dynamics of the robot and deriving the quantity of state at a next time-step, a function of deriving the data of distance measurement at the next step, and a function of calculating the altitude from the data of distance measurement. A difference type network which represents the output with the increment from the input and a learning method which generates temporary instruction data train from the signals reversely propagating the forward network and thereby adjusts the controller network were introduced. Effectiveness of these three technical improvements was demonstrated based on numerical simulation. 4 refs., 12 figs.

Automatic Generation of Machine Emulators: Efficient Synthesis of Robust Virtual Machines for Legacy Software Migration  

DEFF Research Database (Denmark)

As older mainframe architectures become obsolete, the corresponding le- gacy software is increasingly executed via platform emulators running on top of more modern commodity hardware. These emulators are virtual machines that often include a combination of interpreters and just-in-time compilers. Implementing interpreters and compilers for each combination of emulated and target platform independently of each other is a redundant and error-prone task. We describe an alternative approach that automatically synthesizes specialized virtual-machine interpreters and just-in-time compilers, which then execute on top of an existing software portability platform such as Java. The result is a considerably reduced implementation effort.

Reed canary grass as a feedstock for 2nd generation bioethanol production.  

Science.gov (United States)

The enzymatic hydrolysis and fermentation of reed canary grass, harvested in the spring or autumn, and barley straw were studied. Steam pretreated materials were efficiently hydrolysed by commercial enzymes with a dosage of 10-20FPU/g d.m. Reed canary grass harvested in the spring was hydrolysed more efficiently than the autumn-harvested reed canary grass. Additional ?-glucosidase improved the release of glucose and xylose during the hydrolysis reaction. The hydrolysis rate and level of reed canary grass with a commercial Trichoderma reesei cellulase could be improved by supplementation of purified enzymes. The addition of CBH II improved the hydrolysis level by 10% in 48hours' hydrolysis. Efficient mixing was shown to be important for hydrolysis already at 10% dry matter consistency. The highest ethanol concentration (20g/l) and yield (82%) was obtained with reed canary grass at 10% d.m. consistency. PMID:22939601

Twist decomposition of nonlocal light-cone operators II: general tensors of 2nd rank  

International Nuclear Information System (INIS)

A group theoretical procedure, introduced earlier in , to decompose bilocal light-ray operators into (harmonic) operators of definite twist is applied to the case of arbitrary 2nd rank tensors. As a generic example the bilocal gluon operator is considered which gets contributions of twist-2 up to twist-6 from four different symmetry classes characterized by corresponding Young tableaux; also the twist decomposition of the related vector and scalar operators is considered. In addition, we extend these results to various trilocal light-ray operators, like the Shuryak-Vainshtein, the three-gluon and the four-quark operators, which are required for the consideration of higher-twist distribution amplitudes. The present results rely on the knowledge of harmonic tensor polynomials of any order n which have been determined up to the case of 2nd rank symmetric tensor for arbitrary space-time dimension

Crystal structures and phase transformation of deuterated lithium imide, Li2ND  

International Nuclear Information System (INIS)

We have investigated the crystal structure of deuterated lithium imide, Li2ND, by means of neutron and X-ray diffraction. An order-disorder transition occurs near 360K. Below that temperature Li2ND can be described to the same level of accuracy as a disordered cubic (Fd3-bar m) structure with partially occupied Li 32e sites or as a fully occupied orthorhombic (Ima2 or Imm2) structure. The high temperature phase is best characterized as disordered cubic (Fm3-bar m) with D atoms randomized over the 192l sites. Density functional theory calculations complement and support the diffraction analyses. We compare our findings in detail with previous studies

Revised data for 2nd version of nuclear criticality safety handbook/data collection  

International Nuclear Information System (INIS)

This paper outlines the data prepared for the 2nd version of Data Collection of the Nuclear Criticality Safety Handbook. These data are discussed in the order of its preliminary table of contents. The nuclear characteristic parameters (k_?, M"2, D) were derived, and subcriticality judgment graphs were drawn for eleven kinds of fuels which were often encountered in criticality safety evaluation of fuel cycle facilities. For calculation of criticality data, benchmark calculations using the combination of the continuous energy Monte Carlo criticality code MVP and the Japanese Evaluated Nuclear Data Library JENDL-3.2 were made. The calculation errors were evaluated for this combination. The implementation of the experimental results obtained by using NUCEF facilities into the 2nd version of the Data Collection is under discussion. Therefore, related data were just mentioned. A database is being prepared to retrieve revised data easily. (author)

A luminescence spectroscopy study of SrI{sub 2}:Nd{sup 3+} single crystals  

Energy Technology Data Exchange (ETDEWEB)

The paper presents the results of a study on the luminescence of SrI{sub 2}:Nd{sup 3+} single crystals grown by the vertical Bridgman method. The photoluminescence (PL) spectra of SrI{sub 2}:Nd crystals show characteristic lines corresponding to transitions in trivalent Nd{sup 3+} ions, the most intense line at ca. 1070 nm is due to the radiative {sup 4}F{sub 3/2}?{sup 4}I{sub 11/2} transitions. Efficient PL excitation in a crystal transparency band occurs due to optical 4f?4f transitions from the ground {sup 4}I{sub 9/2} state, or the charge transfer transitions I{sup ?}?Nd{sup 3+}. The paper discussed two new PL emission bands at 2.8 and 3.8 eV, associated with the lattice defects formed in SrI{sub 2} crystal at introducing Nd{sup 3+} impurity ions; two intense narrow PL excitation bands at 5.52 and 5.31 eV, originating from free and defect-bound excitons, respectively; an efficient channel of exciton energy transfer between the host lattice and defects. We calculated the H(k) functions of distribution of the elementary relaxations over the reaction rate constants and explained on this basis the nonexponential PL decay kinetics in SrI{sub 2}:Nd{sup 3+} crystal. -- Author-Highlights: • Luminescence spectroscopy study with time-resolution of SrI{sub 2}:Nd{sup 3+} single crystals. • PL emission band at 1070 nm is due to {sup 4}F{sub 3/2}?{sup 4}I{sub 11/2} transitions in Nd{sup 3+} ions. • PL bands at 2.8 and 3.8 eV are due to the lattice defects in SrI{sub 2} Nd{sup 3+} crystals. • Efficient channel of exciton energy transfer between the host lattice and defects. • Nonexponential PL decay kinetics explained in terms of Kohlrausch function.

Software and Algorithms for Solving Computational Geodynamic Problems using Next Generation Hardware  

Science.gov (United States)

Numerical geodynamic modeling is typically based on solving a series of partial differential equations which describe the long-term behavior of the solid visco-elasto-brittle/plastic Earth as a highly viscous incompressible fluid with strongly variable non-Newtonian viscosity. Coding for solving geodynamic equations is catching up with the advance of modern high performance computing. In the past five years, newly developed many-core computing technology, including GPU (Graphics Processing Unit) and MIC (Many Integrated Core), has also been utilized for geodynamic modeling. However, the lack of easy-to-expand or easy-to-use geo-computing toolkits limits the high performance software catching up with the endless updating of high performance hardware. In this presentation, we will firstly show two examples of the implementation of solving geodynamic problems based on Stokes and continuity equations with strongly variable viscosity using many-core hardware, with a specific focus on the GPU. The first example is a geometric multi-grid (GMG) solver, which solves a synthetic sinking cube problem using a staggered grid finite difference discretization. The second example is a preconditioned minimal residual (MINRES) solver for incompressible Stokes flow problem with many viscous inclusions which is discretized using the finite element method. Through these two implementation examples, we will analyze the cost of coding and running advantages and disadvantages of the two kinds of coding methodologies, and in a hope to discuss a potential general coding flowchart for solving geodynamic equations using many-core devices. Finally, a software stack based many-core computing framework oriented to geodynamic modeling is proposed for the future.

Sustainable development - a role for nuclear power? 2nd scientific forum  

International Nuclear Information System (INIS)

The 2nd Scientific Forum of the International Atomic Energy Agency (IAEA) was held during the 43rd General Conference. This paper summarizes the deliberations of the two-day Forum. The definition of 'sustainable development' of the 1987 Bruntland Commission - 'development that meets the needs of the present without compromising the ability of future generations to meet their own needs' - provided the background for the Forum's debate whether and how nuclear power could contribute to sustainable energy development. The framework for this debate comprises different perspectives on economic, energy, environmental, and political considerations. Nuclear power, along with all energy generating systems, should be judged on these considerations using a common set of criteria (e.g., emission levels, economics, public safety, wastes, and risks). First and foremost, there is a growing political concern over the possible adverse impact of increasing emissions of greenhouse gases from fossil fuel combustion. However, there is debate as to whether this would have any material impact on the predominantly economic criteria currently used to make investment decisions on energy production. According to the views expressed, the level of safety of existing nuclear power plants is no longer a major concern - a view not yet fully shared by the general public. The need to maintain the highest standards of safety in operation remains, especially under the mounting pressure of competitiveness in deregulated and liberalized energy markets. The industry must continuously reinforce a strong safety culture among reactor designers, builders, and operators. Furthermore, a convincing case for safety will have to be made for any new reactor designs. Of greater concern to the public and politicians are the issues of radioactive waste and proliferation of nuclear weapons. There is a consensus among technical experts that radioactive wastes from nuclear power can be disposed of safely and economically in deep geologic formations. However, the necessary political decisions to select sites for repositories need public support and understanding about what the industry is doing and what can be done. As to nuclear weapons proliferation, the existing safeguards system must be fully maintained and strengthened and inherently proliferation-resistant fuel cycles should be explored. Overviews of the future global energy demand and of the prospects for nuclear power in various economic regions of the world indicate that, in the case of the OECD countries, the dominant issue is economics in an increasingly free market system for electricity. For the so-called transition economies, countries of the Former Soviet Union and Central and Eastern Europe, the issue is one of managing nuclear power plant operations safely. In the case of developing countries, the dominant concern is effective management of technology, in addition to economics and finance. The prospects for nuclear power depend on the resolution of two cardinal issues. The first is economic competitiveness, and in particular, reduced capital cost. The second is public confidence in the ability of the industry to manage plant operations and its high level waste safely. There is a continuing need for dialogue and communication with all sectors of the public: economists, investors, social scientists, politicians, regulators, unions, and environmentalists. Of help in this dialogue would be nuclear power's relevance to and comparative advantages in addressing environmental issues, such as global climate change, local air quality, and regional acidification. Suggestions have been made for a globalized approach to critical nuclear power issues, such as waste management, innovative and proliferation-resistant reactors and fuel cycles, and international standards for new generation nuclear reactor designs.The conclusion seems to be that there is a role for nuclear energy in sustainable development, especially if greenhouse gas emissions are to be limited. Doubts persist in the minds of many energy experts over the pote

Massive coordination of dispersed generation using PowerMatcher based software agents  

International Nuclear Information System (INIS)

One of the outcomes of the EU-Fifth framework CRISP-project (http://crisp.ecn.nl/), has been the development of a real-time control strategy based on the application of distributed intelligence (ICT) to coordinate demand and supply in electricity grids. This PowerMatcher approach has been validated in two real-life and real-time field tests. The experiments aimed at controlled coordination of dispersed electricity suppliers (DG-RES) and demanders in distributed grids enabled by ICT-networks. Optimization objectives for the technology in the tests were minimization of imbalance in a commercial portfolio and mitigation of strong load variations in a distribution network with residential micro-CHPs. With respect to the number of ICT-nodes, the field tests were on a relatively small-scale. However, application of the technology has yielded some very encouraging results in both occasions. In the present paper, lessons learned from the field experiments are discussed. Furthermore, it contains an account of the roadmap for scaling up these field-tests with a larger number of nodes and with more diverse appliance/installation types. Due to its autonomous decision making agent-paradigm, the PowerMatcher software technology is expected to be widely more scaleable than central coordination approaches. Indeed, it is based on microeconomic theory and is expected to work best if it is applied on a massive scale in transparent market settings. A set of various types of supply and demand appliances was defined and implemented in a PowerMatcher software simulation environment. A massive amount of these PowerMatcher node-agents each representing such a devicetype was utilized in a number of scenario calculations. As the production of DG-RES-resources and the demand profiles are strongly dependent on the time-of-year, climate scenarios leading to operational snapshots of the cluster were taken for a number of representative periods. The results of these larger scale simulations as well as scalability issues, encountered, are discussed. Further issues covered are the stability of the system as reflected by the internal price development pattern that acts as an 'invisible hand' to reach the common optimisation goal. Finally, the effects of scaling-up the technology are discussed in terms of possible 'emergent behaviour' of subsets in the cluster and primary process quality of appliances operating concertedly using the PowerMatcher

Transition energy and dipole oscillator strength for 1s22p-1s2nd of Cr21+ ion  

International Nuclear Information System (INIS)

The transition energies, wavelengths and dipole oscillator strengths of 1s22p-1s2nd (3 ? n ? 9) for Cr21+ ion are calculated. The fine structure splittings of 1s2nd (n ? 9) states for this ion are also calculated. In calculating energy, we have estimated the higher-order relativistic contribution under a hydrogenic approximation. The quantum defect of Rydberg series 1s2nd is determined according to the quantum defect theory. The results obtained in this paper excellently agree with the experimental data available in the literature. Combining the quantum defect theory with the discrete oscillator strengths, the discrete oscillator strengths for the transitions from initial state 1s22p to highly excited 1s2nd states (n ? 10) and the oscillator strength density corresponding to the bound—free transitions are obtained.

Quantification of epigenetic and genetic 2nd hits in CDH1 during hereditary diffuse gastric cancer syndrome progression  

Digital Repository Infrastructure Vision for European Research (DRIVER)

BACKGROUND & AIMS: Hereditary diffuse gastric cancer (HDGC) families carry CDH1 heterozygous germline mutations; their tumors acquire complete CDH1 inactivation through "2nd-hit" mechanisms. Most frequently, this occurs via promoter hypermethylation (epigenetic modification), and less frequently via CDH1 mutations and loss of heterozygosity (LOH). We quantified the different 2nd hits in CDH1 occurring in neoplastic lesions from HDGC patients.

Application to non-destructive assay of 2nd layer tail cylinder at Rokkasho Enrichment plant  

International Nuclear Information System (INIS)

International Atomic Energy Agency (IAEA) safeguards criteria 93+2 requirement stipulates that depleted uranium under the single C/S (Metal or Camera) is re-verified with 10% coverage (?=0.9) once a year, normally during physical inventory verification. In order to maintain the continuity of knowledge, the entire depleted uranium cylinders transferred from the processing area are sealed by inspectorates (the state and the IAEA) after sufficient verification with 50% coverage (?=0.5). At Rokkasho Enrichment plant, the depleted uranium cylinder (0.2?0.3% enrichment of tail cylinder centrifuged by cascade) separated at the processing area is stored in the cylinder storage. The 2nd layer tail cylinder pile-up has been adopted for efficient-use of the storage; one block is comprised of four cylinders on the lower, three on the upper. The capacity of the specific cylinder crane is limited to as low as height of the upper cylinder. Current lifter with germanium detector is applied to the lower cylinder. However, it is highly possible that inspectorate selects random for the upper tail cylinder at the physical inventory verification. Therefore, at the verification, the operators corporate to lift down the 2nd layer tail cylinder to ground floor so that inspectorate is able to verify it. The Nuclear Material Control Center (NMCC) has designed and manufactured the specific detector lifter capable of the 2nd layer measurement and the potable detector's collimator. Afterwards, we conducted a site test in the plant and inspection efficiency and reduced operator's burden. (author)

jMHC: software assistant for multilocus genotyping of gene families using next-generation amplicon sequencing.  

Science.gov (United States)

Genotyping of multilocus gene families, such as the major histocompatibility complex (MHC), may be challenging because of problems with assigning alleles to loci and copy number variation among individuals. Simultaneous amplification and genotyping of multiple loci may be necessary, and in such cases, next-generation deep amplicon sequencing offers a great promise as a genotyping method of choice. Here, we describe jMHC, a computer program developed for analysing and assisting in the visualization of deep amplicon sequencing data. Software operates on FASTA files; therefore, output from any sequencing technology may be used. jMHC was designed specifically for MHC studies but it may be useful for analysing amplicons derived from other multigene families or for genotyping other polymorphic systems. The program is written in Java with user-friendly graphical interface (GUI) and can be run on Microsoft Windows, Linux OS and Mac OS. PMID:21676201

Radcalc for windows benchmark study: A comparison of software results with Rocky Flats hydrogen gas generation data  

International Nuclear Information System (INIS)

Radcalc for Windows Version 2.01 is a user-friendly software program developed by Waste Management Federal Services, Inc., Northwest Operations for the U.S. Department of Energy (McFadden et al. 1998). It is used for transportation and packaging applications in the shipment of radioactive waste materials. Among its applications are the classification of waste per the US. Department of Transportation regulations, the calculation of decay heat and daughter products, and the calculation of the radiolytic production of hydrogen gas. The Radcalc program has been extensively tested and validated (Green et al. 1995, McFadden et al. 1998) by comparison of each Radcalc algorithm to hand calculations. An opportunity to benchmark Radcalc hydrogen gas generation calculations to experimental data arose when the Rocky Flats Environmental Technology Site (RFETS) Residue Stabilization Program collected hydrogen gas generation data to determine compliance with requirements for shipment of waste in the TRUPACT-II (Schierloh 1998). The residue/waste drums tested at RFETS contain contaminated, solid, inorganic materials in polyethylene bags. The contamination is predominantly due to plutonium and americium isotopes. The information provided by Schierloh (1 998) of RFETS includes decay heat, hydrogen gas generation rates, calculated Geff values, and waste material type, making the experimental data ideal for benchmarking Radcalc. The following sections discuss the RFETS data and the Radcalc cases modeled with the data. Results are tabulated and also provided graphically

International Nuclear Information System (INIS)

A sensitive submillimeter heterodyne receiver has been used to measure electron cyclotron emission at the 2nd through the 5th harmonics from thermal plasmas in Alcator A. A sensitive diagnostic of the electron energy distribution function is obtained from intensity ratios of the optically thin harmonics, in particular the small runaway fraction (approx.10-6) that exists even in well thermalized Alcator A plasmas. Also the 4th and 5th harmonics are a sensitive measure of impending plasma disruption due to vessel air leaks

The ratio of 2nd to 4th digit length: a new predictor of disease predisposition?  

Science.gov (United States)

The ratio between the length of the 2nd and 4th digits is: (a) fixed in utero; (b) lower in men than in women; (c) negatively related to testosterone and sperm counts; and (d) positively related to oestrogen concentrations. Prenatal levels of testosterone and oestrogen have been implicated in infertility, autism, dyslexia, migraine, stammering, immune dysfunction, myocardial infarction and breast cancer. We suggest that 2D:4D ratio is predictive of these diseases and may be used in diagnosis, prognosis and in early life-style interventions which may delay the onset of disease or facilitate its early detection.

Dielectric studies of CaF_2:Nd single crystals from RT to 350 "0C  

International Nuclear Information System (INIS)

Dielectric measurements of CaF_2:Nd single crystals from RT to 350 "0C are carried out at different frequencies (10"2, 10"3, 10"4, and 10"5 Hz). Variation of the real part of dielectric constant ?' and the dielectric loss (tan ?) with temperature at a particular frequency and the variation of ?' and tan ? with frequency at a particular temperature are studied. Also, the activation energy in the frequency independent region of the ac conductivity plot is calculated and compared with earlier results. (author)

Group field theory as the 2nd quantization of Loop Quantum Gravity  

CERN Document Server

We construct a 2nd quantized reformulation of canonical Loop Quantum Gravity at both kinematical and dynamical level, in terms of a Fock space of spin networks, and show in full generality that it leads directly to the Group Field Theory formalism. In particular, we show the correspondence between canonical LQG dynamics and GFT dynamics leading to a specific GFT model from any definition of quantum canonical dynamics of spin networks. We exemplify the correspondence of dynamics in the specific example of 3d quantum gravity. The correspondence between canonical LQG and covariant spin foam models is obtained via the GFT definition of the latter.

Multigrid preconditioning of the generator two-phase mixture balance equations in the Genepi software  

Energy Technology Data Exchange (ETDEWEB)

In the framework of the two-phase fluid simulations of the steam generators of pressurized water nuclear reactors, we present in this paper a geometric version of a pseudo-Full MultiGrid (pseudo- FMG) Full Approximation Storage (FAS) preconditioning of balance equations in the GENEPI code. In our application, the 3D steady state flow is reached by a transient computation using a semi-implicit fractional step algorithm for the averaged two-phase mixture balance equations (mass, momentum and energy for the secondary flow). Our application, running on workstation clusters, is based on a CEA code-linker and the PVM package. The difficulties to apply the geometric FAS multigrid method to the momentum and mass balance equations are addressed. The use of a sequential pseudo-FMG FAS twogrid method for both energy and mass/momentum balance equations, using dynamic multigrid cycles, leads to perceptibly improvements in the computation convergences. An original parallel red-black pseudo-FMG FAS three-grid algorithm is presented too. The numerical tests (steam generator mockup simulations) underline the sizable increase in speed of convergence of the computations, essentially for the ones involving a large number of freedom degrees (about 100 thousand cells). The two-phase mixture balance equation residuals are quickly reduced: the reached speed-up stands between 2 and 3 following the number of grids. The effects on the convergence behavior of the numerical parameters are investigated.

Mid-water Software Tools and the Application to Processing and Analysis of the Latest Generation Multibeam Sonars  

Science.gov (United States)

The latest generation of multibeam sonars now has the ability to map the water-column, along with the seafloor. Currently, the users of these sonars have a limited view of the mid-water data in real-time, and if they do store the data, they are restricted to replaying it only, with no ability for further analysis. The water-column data has the potential to address a number of research areas including detection of small targets (wrecks, etc.) above the seabed, mapping of fish and marine mammals and a wide range of physical oceanographic processes. However, researchers have been required to develop their own in-house software tools before they can even begin their study of the water column data. This paper describes the development of more general software tools for the full processing of raw sonar data (bathymetry, backscatter and water-column) to yield output products suitable for visualization in a 4D time-synchronized environment. The huge water-column data volumes generated by the new sonars, combined with the variety of data formats from the different sonar manufacturers, provides a significant challenge in the design and development of tools that can be applied to the wide variety of applications. The development of the mid-water tools on this project addressed this problem by using a unified way of storing the water column data in a generic water column format (GWC). The sonar data are converted into the GWC by re-integrating the water column packets with time-based navigation and attitude, such that downstream in the workflow, the tools will have access to all relevant data of any particular ping. Dependent on the application and the resolution requirements, the conversion process also allows simple sub-sampling. Additionally, each file is indexed to enable fast non-linear lookup and extraction of any packet type or packet type collection in the sonar file. These tools also fully exploit multi-core and hyper-threading technologies to maximize the throughput of the significant volume of water column data. Currently, the source conversion system supports a wide variety of hydrographic and fisheries sonars such as the Kongsberg EM3002, EM302, EM122, ME70, EK60, EK500 and Reson 7125. It is proposed that the GWC format be public, and it has been distributed for review and comment to researchers, sonar manufacturers and software developers (http://www.ivs3d.com/support/gwc/). 3-D view of the bubble plume NW Rota Volcano.

Characterization of the 1st and 2nd EF-hands of NADPH oxidase 5 by fluorescence, isothermal titration calorimetry, and circular dichroism  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Superoxide generated by non-phagocytic NADPH oxidases (NOXs is of growing importance for physiology and pathobiology. The calcium binding domain (CaBD of NOX5 contains four EF-hands, each binding one calcium ion. To better understand the metal binding properties of the 1st and 2nd EF-hands, we characterized the N-terminal half of CaBD (NCaBD and its calcium-binding knockout mutants. Results The isothermal titration calorimetry measurement for NCaBD reveals that the calcium binding of two EF-hands are loosely associated with each other and can be treated as independent binding events. However, the Ca2+ binding studies on NCaBD(E31Q and NCaBD(E63Q showed their binding constants to be 6.5 × 105 and 5.0 × 102 M-1 with ?Hs of -14 and -4 kJ/mol, respectively, suggesting that intrinsic calcium binding for the 1st non-canonical EF-hand is largely enhanced by the binding of Ca2+ to the 2nd canonical EF-hand. The fluorescence quenching and CD spectra support a conformational change upon Ca2+ binding, which changes Trp residues toward a more non-polar and exposed environment and also increases its ?-helix secondary structure content. All measurements exclude Mg2+-binding in NCaBD. Conclusions We demonstrated that the 1st non-canonical EF-hand of NOX5 has very weak Ca2+ binding affinity compared with the 2nd canonical EF-hand. Both EF-hands interact with each other in a cooperative manner to enhance their Ca2+ binding affinity. Our characterization reveals that the two EF-hands in the N-terminal NOX5 are Ca2+ specific.

PCID and ASPIRE 2.0 - The Next Generation of AMOS Image Processing Software  

Science.gov (United States)

One of the missions of the Air Force Maui Optical and Supercomputing (AMOS) site is to generate high-resolution images of space objects using the Air Force telescopes located on Haleakala. Because atmospheric turbulence greatly reduces the resolution of space object images collected with ground-based telescopes, methods for overcoming atmospheric blurring are necessary. One such method is the use of adaptive optics systems to measure and compensate for atmospheric blurring in real time. A second method is to use image restoration algorithms on one or more short-exposure images of the space object under consideration. At AMOS, both methods are used routinely. In the case of adaptive optics, rarely can all atmospheric turbulence effects be removed from the imagery, so image restoration algorithms are useful even for adaptive-optics-corrected images. Historically, the bispectrum algorithm has been the primary image restoration algorithm used at AMOS. It has the advantages of being extremely fast (processing times of less than one second) and insensitive to atmospheric phase distortions. In addition, multi-frame blind deconvolution (MFBD) algorithms have also been used for image restoration. It has been observed empirically and with the use of computer simulation studies that MFBD algorithms produce higher-resolution image restorations than does the bispectrum algorithm. MFBD algorithms also do not need separate measurements of a star in order to work. However, in the past, MFBD algorithms have been factors of one hundred or more slower than the bispectrum algorithm, limiting their use to non-time-critical image restorations. Recently, with the financial support of AMOS and the High-Performance Computing Modernization Office, an MFBD algorithm called Physically-Constrained Iterative Deconvolution (PCID) has been efficiently parallelized and is able to produce image restorations in only a few seconds. In addition, with the financial support of AFOSR, it has been shown that PCID achieves or closely approaches the theoretical limits to image restoration quality for a variety of scenarios. For these reasons, PCID is now being transitioned to being the site-wide image restoration algorithm. Because the algorithm can be complicated to use, a GUI is being developed to be the front end to the PCID algorithm. This interface, called the Advanced SPeckle Image Reconstruction Environment (ASPIRE) version 2.0, is the next generation of the current ASPIRE GUI used as a front end to the bispectrum algorithm. ASPIRE 2.0 will be the front-end GUI to PCID, the bispectrum algorithm, and the AMOSphere database. In this presentation we describe ASPIRE 2.0 and PCID and how to use them to obtain high-resolution images.

Nonlinear Dynamics of Memristor Based 2nd and 3rd Order Oscillators  

Exceptional behaviours of Memristor are illustrated in Memristor based second order (Wien oscillator) and third order (phase shift oscillator) oscillator systems in this Thesis. Conventional concepts about sustained oscillation have been argued by demonstrating the possibility of sustained oscillation with oscillating resistance and dynamic poles. Mathematical models are also proposed for analysis and simulations have been presented to support the surprising characteristics of the Memristor based oscillator systems. This thesis also describes a comparative study among the Wien family oscillators with one Memristor. In case of phase shift oscillator, one Memristor and three Memristors systems are illustrated and compared to generalize the nonlinear dynamics observed for both 2nd order and 3rd order system. Detail explanations are provided with analytical models to simplify the unconventional properties of Memristor based oscillatory systems.

Belief Functions: Theory and Applications - Proceedings of the 2nd International Conference on Belief Functions  

CERN Document Server

The theory of belief functions, also known as evidence theory or Dempster-Shafer theory, was first introduced by Arthur P. Dempster in the context of statistical inference, and was later developed by Glenn Shafer as a general framework for modeling epistemic uncertainty. These early contributions have been the starting points of many important developments, including the Transferable Belief Model and the Theory of Hints. The theory of belief functions is now well established as a general framework for reasoning with uncertainty, and has well understood connections to other frameworks such as probability, possibility and imprecise probability theories.   This volume contains the proceedings of the 2nd International Conference on Belief Functions that was held in Compiègne, France on 9-11 May 2012. It gathers 51 contributions describing recent developments both on theoretical issues (including approximation methods, combination rules, continuous belief functions, graphical models and independence concepts) an...

Full Text Available Abstract The International Symposium "Peripheral Nerve Repair and Regeneration and 2nd Club Brunelli Meeting" was held on December 4-5, 2009 in Turin, Italy (Organizers: Bruno Battiston, Stefano Geuna, Isabelle Perroteau, Pierluigi Tos. Interest in the study of peripheral nerve regeneration is very much alive because complete recovery of nerve function almost never occurs after nerve reconstruction and, often, the clinical outcome is rather poor. Therefore, there is a need for defining innovative strategies for improving the success of recovery after nerve lesion and repair and this meeting was intended to discuss, from a multidisciplinary point of view, some of today's most important issues in this scientific field, arising from both basic and clinical neurosciences.

Production of artificial ionospheric layers by frequency sweeping near the 2nd gyroharmonic  

Science.gov (United States)

Artificial ionospheric plasmas descending from the background F-region have been observed on multiple occasions at the High Frequency Active Auroral Research Program (HAARP) facility since it reached full 3.6 MW power. Proximity of the transmitter frequency to the 2nd harmonic of the electron gyrofrequency (2fce) has been noted as a requirement for their occurrence, and their disappearance after only a few minutes has been attributed to the increasing frequency mismatch at lower altitudes. We report new experiments employing frequency sweeps to match 2fce in the artificial plasmas as they descend. In addition to revealing the dependence on the 2fce resonance, this technique reliably produces descending plasmas in multiple transmitter beam positions and appears to increase their stability and lifetime. High-speed ionosonde measurements are used to monitor the altitude and density of the artificial plasmas during both the formation and decay stages.

A critical discussion of the 2nd intercomparison on electron paramagnetic resonance dosimetry with tooth enamel  

International Nuclear Information System (INIS)

Recently, we have participated in 'The 2nd International Intercomparison on EPR Tooth Dosimetry' wherein 18 laboratories had to evaluate low-radiation doses (100-1000 mGy) in intact teeth (Wieser et al., Radiat. Meas., 32 (2000a) 549). The results of this international intercomparison seem to indicate a promising picture of EPR tooth dosimetry. In this paper, the two Belgian EPR participants present a more detailed and critical study of their contribution to this intercomparison. The methods used were maximum likelihood common factor analysis (MLCFA) and spectrum subtraction. Special attention is paid to potential problems with sample preparation, intrinsic dose evaluation, linearity of the dose response, and determination of dose uncertainties

Full Text Available SciELO Colombia | Language: Spanish Abstract in spanish Actualmente en el entorno del comercio electrónico es necesario contar con herramientas que permitan obtener conocimiento útil que brinde soporte a la toma de decisiones de marketing; para ello se necesita de un proceso que utiliza una serie de técnicas para el procesamiento de los datos, entre ella [...] s se encuentra la minería de datos, que permite llevar a cabo un proceso de descubrimiento de información automático. Este trabajo tiene como objetivo presentar la técnica de reglas de asociación como la adecuada para descubrir cómo compran los clientes en una empresa que ofrece un servicio de comercio electrónico tipo B2C, con el fin de apoyar la toma de decisiones para desarrollar ofertas hacia sus clientes o cautivar nuevos. Para la implementación de las reglas de asociación existe una variedad de algoritmos como: A priori, DHP, Partition, FP-Growth y Eclat y para seleccionar el más adecuado se define una serie de criterios (Danger y Berlanga, 2001), entre los que se encuentran: inserciones a la base de datos, costo computacional, tiempo de ejecución y rendimiento, los cuales se analizaron en cada algoritmo para realizar la selección. Además, se presenta el desarrollo de una herramienta software que contempla la metodología CRISP-DM constituida por cuatro submódulos, así: Preprocesamiento de datos, Minería de datos, Análisis de resultados y Aplicación de resultados. El diseño de la aplicación utiliza una arquitectura de tres capas: Lógica de presentación, Lógica del Negocio y Lógica de servicios; dentro del proceso de construcción de la herramienta se incluye el diseño de la bodega de datos y el diseño de algoritmo como parte de la herramienta de minería de datos. Las pruebas hechas a la herramienta de minería de datos desarrollada se realizaron con una base de datos de la compañía FoodMart3. Estas pruebas fueron de: rendimiento, funcionalidad y confiabilidad en resultados, las cuales permiten encontrar reglas de asociación igualmente. Los resultados obtenidos facilitaron concluir, entre otros aspectos, que las reglas de asociación como técnica de minería de datos permiten analizar volúmenes de datos para servicios de comercio electrónico tipo B2C, lo cual es una ventaja competitiva para las empresas. Abstract in english Tools leading to useful knowledge being obtained for supporting marketing decisions being taken are currently needed in the ecommerce environment. A process is needed for this which uses a series of techniques for data-processing; data-mining is one such technique enabling automatic information disc [...] overy. This work presents the association rules as a suitable technique for discovering how customers buy from a company offering business to consumer (B2C) e-business, aimed at supporting decision-making in supplying its customers or capturing new ones. Many algorithms such as A priori, DHP, Partition, FP-Growth and Eclat are available for implementing association rules; the following criteria were defined for selecting the appropriate algorithm: database insert, computational cost, performance and execution time. The development of a software tool is also presented which involved the CRISP-DM approach; this software tool was formed by the following four sub-modules: data pre-processing, data-mining, results analysis and results application. The application design used three-layer architecture: presentation logic, business logic and service logic. Data warehouse design and algorithm design were included in developing this data-mining software tool. It was tested by using a FoodMart company database; the tests included performance, functionality and results? validity, thereby allowing association rules to be found. The results led to concluding that using association rules as a data mining technique facilitates analysing volumes of information for B2C e-business services which represents a competitive advantage for those companies using Internet as their sales? media.

Transition Energy and Oscillator Strength of 1s2 2p – 1s2nd for Fe23+ ion  

International Nuclear Information System (INIS)

Transition energies, wavelengths and dipole oscillator strengths of 1s22p – 1s2nd (3 ? n ? 9) for Fe23+ ion are calculated. The fine structure splittings of 1s2nd (n ? 9) states for this ion are also evaluated. The higher-order relativistic contribution to the energy is estimated under a hydrogenic approximation. The quantum defect of Rydberg series 1s2nd is determined according to the quantum defect theory. The energies of any highly excited states with (n ? 10) for this series can be reliably predicted using these quantum defects as input. The results in this paper excellently agree with the experimental data available in the literature. Combining the quantum defect theory with the discrete oscillator strengths, the discrete oscillator strengths for the transitions from same given initial state 1s22p to highly excited 1s2nd states (n ? 10) and the oscillator strength density corresponding to the bound-free transitions is obtained.

Comparative analysis of 1st, 2nd, and 4th year MD students' attitudes toward Complementary Alternative Medicine (CAM  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background To identify and report the attitudes and beliefs of 1st, 2nd, and 4th year medical students toward complementary alternative medicine (CAM. Methods The previously validated and reliability tested CHBQ was administered to medical students attending the University of South Florida School of Medicine. Results Significant changes were found between both 1st (46.0 ± 7.7 and 4th (37.8 ± 15.7 year students and 2nd (48.3 ± 7.8 and 4th (37.8 ± 15.7 year students. No significant difference was found between 1st (46.0 ± 7.7 and 2nd (48.3 ± 7.8 year students. When comparing scores based on gender, a significant difference was present between males (41.2 ± 12.2 and females (46.1 ± 11.0. Conclusion CHBQ scores were significantly more positive in both 1st and 2nd year medical students in comparison with 4th year student's scores. These findings suggest that as student exposure to allopathic techniques and procedures increases during the last year of medical school, their attitudes toward CAM decrease. Females were also significantly more likely to have stronger positive attitudes toward CAM than males, though both genders represented an overall positive attitude toward CAM.

The 2nd and 3rd lower molars development of in utero gamma irradiated mouse fetus and neonates  

International Nuclear Information System (INIS)

Pregnant mothers were irradiated by a single dose of gamma rays (0, 2, 4, 6 Gy cobalt 60) in the days 10, 12, 14, 16, 18 of pregnancy. The heads of the embryos, and those of the neonates were taken at consecutive intervals of irradiation, starting from 16 days of pregnancy till 3rd day after delivery. The effect of irradiation was investigated in the development of the 2nd and 3rd lower molars on serial tissue sections, within consecutive periods of their organogenesis. Irradiation led to growth-deficiency in the 2nd and 3rd molars, and causes delay in their development. This was observed in various degree depending on the dose, time of irradiation, and time after irradiation. This belated development was manifested in morphogenesis, histogenesis, and odontoblasts and ameloblastis cyto and functional differentiations. The study showed that the delay in the development-stages of the 2nd lower molar, under control, if compared with the same process, to which is exposed, the 1st lower molar - within two days difference - dose not diminish the later irradiation effect on the 2nd molar, when compared with the immediate irradiation effect in the 1st molar (demonstrated in a previous study by Osman and Al-Achkar, 2001). On the contrary, the present study showed that the 2nd lower molar is more radiosensitive to various doses than the 1st lower molar. Also it showed the irradiation with two doses 4 and 6 Gy leads to a delay in the formation of the 3rd lower molar's bud, and it does not go deeper beyond the lower molar. (Author)

First case of Fusobacterium necrophorum endocarditis to have presented after the 2nd decade of life.  

Science.gov (United States)

Fusobacterium necrophorum, an obligate, anaerobic, filamentous, gram-negative rod, is thought to be a normal inhabitant of the mucous membranes in human beings. Fusobacterium species have been implicated in cases of Lemierre syndrome and other pathologic conditions. Their reported association with infective endocarditis is extremely rare. We describe the case of a previously healthy 34-year-old man who emergently presented with flu-like symptoms and dyspnea on exertion. He had recently undergone a dental procedure. Empiric antibiotic therapy was initiated. Blood cultures were positive for metronidazole-resistant F. necrophorum. A transesophageal echocardiogram revealed 2 mobile vegetations on the mitral valve. Despite the antibiotic therapy, the patient's respiratory status worsened and, after 3 weeks, he died. On the basis of the organism's pathophysiology and the patient's recent dental procedure, the oral cavity was the likely source of the bacteremia. Our patient's case underscores the importance of recognizing Fusobacterium bacteremia as a possible cause of endocarditis. To our knowledge, this is the first reported case of monomicrobial F. necrophorum endocarditis to have presented in a patient after the 2nd decade of life. In addition, it is apparently only the 4th report of F. necrophorum mitral valve endocarditis with case results derived from modern culture techniques. PMID:24082377

[Quality of medical records in Naples (Italy) 2nd University School of Medicine].  

Science.gov (United States)

To evaluate and improve the quality of medical-record keeping, in clinics and surgery departments. The evaluation involved 66 Operative Units (O.U.) of the "2nd University Hospital" in Naples (Italy). 10 medical records for each O.U. were randomly selected, for a total of 660. The quality was evaluated in all sections of medical records using the criteria of completeness, clarity and traceability of the data. The most critical issues are: unclear handwriting in almost all sections, in the whole scarse presence of a discharge letter (17.0%) in surgery (1.4%), almost total absence of the physicians signature in the clinical diary (2.3%). The completeness of medical records (presence of patient's history, physical examination, informed consent) is significantly higher in the surgery departments. The medical records are significantly righter in the clinic departments. In general, a poor quality of medical-record keeping was detected. This indicates the need to improve the quality by involving the staff in the importance of correct compilation. PMID:19014110

Alpha irradiation effects in Ca2Nd8(SiO4)6O2  

International Nuclear Information System (INIS)

The effects of alpha irradiation in the rare-earth silicate, Ca2Nd8(SiO4)6O2, was investigated by x-ray diffraction, x-ray absorption near-edge spectroscopy (XANES), and extended x-ray fine structure (EXAFS) techniques. Irradiation with alpha particles emitted isotropically from a 238PuO2 source to a cumulative dose of 2.25 times 1021 alphas/m2 (0.36 dpa) produced measurable anisotropic lattice expansions, with no tendency toward the amorphization that was previously reported due to self-radiation damage in Cm-doped samples at similar displacement-damage (0.25 dpa) levels. The unit-cell volume expanded exponentially with dose to a value corresponding to 2.5% expansion at saturation. The fluorescence XANES data of irradiated surfaces indicate a rearrangement of the near-neighbor ions about Nd. The EXAFS results indicate an irradiation-induced increase in structural disorder that becomes readily apparent at distances of several coordination spheres away from Nd. 14 refs., 5 figs

Contributors are invited to submit research that deals with different facets of contemporary approaches to design education research. All papers will be double-blind peer-reviewed. This conference is open to research in any aspect and discipline of design educationConference themeDesign Learning for Tomorrow - Design Education from Kindergarten to PhDDesigned artefacts and solutions influence our lives and values, both from a personal and societal perspective. Designers, decision makers, investors and consumers hold different positions in the design process, but they all make choices that will influence our future visual and material culture. To promote sustainability and meet global challenges for the future, professional designers are dependent on critical consumers and a design literate general public.  For this purpose design education is important for all. We propose that design education in general education represents both a foundation for professional design education and a vital requirement for developing the general public’s competence for informed decision making.REGISTRATION AT http://www.hioa.no/DRScumulus

Studies with Ferrous Sulfamate and Alternate Reductants for 2nd Uranium Cycle  

International Nuclear Information System (INIS)

A wide range of miniature mixer-settler tests were conducted to determine the source of iron and sulfur contamination in the uranium product stream (''1EU'') of H Canyon's 2nd Uranium Cycle. The problem was reproduced on the laboratory scale mixer-settlers by changing the feed location of ferrous sulfamate from stage D4 to stage D1. Other process variables effected no change. It was later determined that ferrous sulfamate (FS) solids had plugged the FS line to stage D4, causing FS to backup a ventline and enter the Canyon process at stage D1. Pluggage was almost certainly due to precipitation of FS solids during extended process downtime. During the search for the root cause, tests showed that FS solids were quite small (1-10 mm), and a portion of them could bypass the current Canyon prefilter (3-mm). Also, additional tests were done to find an alternate means of reducing and thereby removing plutonium and neptunium from the uranium product. These tests showed that FS was a more effective reductant than either ascorbic acid or a hydroxylamine nitrate (HAN) / dilute FS combination

??????????????????? Reservoir Characteristics of 2nd Member of Jialingjiang Formation in Fuchengzhai Structure of East Sichuan  

Directory of Open Access Journals (Sweden)

Full Text Available ????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????–??????–????????????????2?????1???????3?????????????????????????????????????????????????????????????????????????????????????????????????????????????????????Based on the core description, thin sections identification, and physical property data analysis, reservoir char- acteristics of 2nd member of Jialingjiang Formation in Fuchengzhai area, eastern Sichuan, are studied in detail. The results show that the rock types of T1j2 are limestone, dolostone and cream rock, and reservoir rocks are mainly crystal- line dolostone and grain dolostone. The combination analysis of casting thin sections and scanning electron microscopy shows that reservoir space mainly exists in secondary pores (inter-grain pore, intercrystal pore, inter-crystal dissolved pore and fractures. The mass-properties analysis indicates that the reservoir property of T1j2 is poor, which belongs to fracture-pore and pore-fracture reservoir. Favourable reservoirs are mainly developed in T1j22, less in T1j21, and least in T1j23. Moreover, the reservoirs of T1j2 are mainly controlled by rock types, distributions of sedimentary facies, diagene- sis forms, tectonic actions, and so on, among which bank and tidal flat of dolomite are favourable reservoir facies, dis- solution and dolomization contribute to diagenesis, and microfractures shaped in tectonic activity are conducive to form the high quality reservoir and develop its permeability.

Mesocosm soil ecological risk assessment tool for GMO 2nd tier studies  

DEFF Research Database (Denmark)

Ecological Risk Assessment (ERA) of GMO is basically identical to ERA of chemical substances, when it comes to assessing specific effects of the GMO plant material on the soil ecosystem. The tiered approach always includes the option of studying more complex but still realistic ecosystem level effects in 2nd tier caged experimental systems, cf. the new GMO ERA guidance: EFSA Journal 2010; 8(11):1879. We propose to perform a trophic structure analysis, TSA, and include the trophic structure as an ecological endpoint to gain more direct insight into the change in interactions between species, i.e. the food-web structure, instead of relying only on the indirect evidence from population abundances. The approach was applied for effect assessment in the agro-ecosystem where we combined factors of elevated CO2, viz. global climate change, and GMO plant effects. A multi-species (Collembola, Acari and Enchytraeidae) mesocosm factorial experiment was set up in a greenhouse at ambient CO2 and 450 ppm CO2 with a GM barley variety and conventional varieties. The GM barley differed concerning the composition of amino acids in the grain (antisense C-hordein line). The fungicide carbendazim acted as a positive control. After 5 and 11 weeks, data on populations, plants and soil organic matter decomposition were evaluated. Natural abundances of stable isotopes, 13C and 15N, of animals, soil, plants and added organic matter (crushed maize leaves) were used to describe the soil food web structure.

An open-source software tool for the generation of relaxation time maps in magnetic resonance imaging  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background In magnetic resonance (MR imaging, T1, T2 and T2* relaxation times represent characteristic tissue properties that can be quantified with the help of specific imaging strategies. While there are basic software tools for specific pulse sequences, until now there is no universal software program available to automate pixel-wise mapping of relaxation times from various types of images or MR systems. Such a software program would allow researchers to test and compare new imaging strategies and thus would significantly facilitate research in the area of quantitative tissue characterization. Results After defining requirements for a universal MR mapping tool, a software program named MRmap was created using a high-level graphics language. Additional features include a manual registration tool for source images with motion artifacts and a tabular DICOM viewer to examine pulse sequence parameters. MRmap was successfully tested on three different computer platforms with image data from three different MR system manufacturers and five different sorts of pulse sequences: multi-image inversion recovery T1; Look-Locker/TOMROP T1; modified Look-Locker (MOLLI T1; single-echo T2/T2*; and multi-echo T2/T2*. Computing times varied between 2 and 113 seconds. Estimates of relaxation times compared favorably to those obtained from non-automated curve fitting. Completed maps were exported in DICOM format and could be read in standard software packages used for analysis of clinical and research MR data. Conclusions MRmap is a flexible cross-platform research tool that enables accurate mapping of relaxation times from various pulse sequences. The software allows researchers to optimize quantitative MR strategies in a manufacturer-independent fashion. The program and its source code were made available as open-source software on the internet.

Comparison of strong gravitational lens model software II. HydraLens: Computer-assisted strong gravitational lens model generation and translation  

Science.gov (United States)

The behavior of strong gravitational lens model software in the analysis of lens models is not necessarily consistent among the various software available, suggesting that the use of several models may enhance the understanding of the system being studied. Among the publicly available codes, the model input files are heterogeneous, making the creation of multiple models tedious. An enhanced method of creating model files and a method to easily create multiple models, may increase the number of comparison studies. HydraLens simplifies the creation of model files for four strong gravitational lens model software packages, including Lenstool, Gravlens/Lensmodel, glafic and PixeLens, using a custom-designed GUI for each of the four codes that simplifies the entry of the model for each of these codes, obviating the need for user manuals to set the values of the many flags and in each data field. HydraLens is designed in a modular fashion, which simplifies the addition of other strong gravitational lens codes in the future. HydraLens can also translate a model generated for any of these four software packages into any of the other three. Models created using HydraLens may require slight modifications, since some information may be lost in the translation process. However the computer-generated model greatly simplifies the process of developing multiple lens models. HydraLens may enhance the number of direct software comparison studies and also assist in the education of young investigators in gravitational lens modeling. Future development of HydraLens will further enhance its capabilities.

Madeira Extreme Floods: 2009/2010 Winter. Case study - 2nd and 20th of February  

Science.gov (United States)

Floods are at world scale the natural disaster that affects a larger fraction of the population. It is a phenomenon that extends it's effects to the surrounding areas of the hydrographic network (basins, rivers, dams) and the coast line. Accordingly to USA FEMA (Federal Emergency Management Agency) flood can be defined as:"A general and temporary condition of partial or complete inundation of two or more acres of normally dry land area or of two or more properties from: Overflow of inland or tidal waters; Unusual and rapid accumulation or runoff of surface waters from any source; Mudflow; Collapse or subsidence of land along the shore of a lake or similar body of water as a result of erosion or undermining caused by waves or currents of water exceeding anticipated cyclical levels that result in a flood as defined above." A flash flood is the result of intense and long duration of continuous precipitation and can result in dead casualties (i.e. floods in mainland Portugal in 1967, 1983 and 1997). The speed and strength of the floods either localized or over large areas, results in enormous social impacts either by the loss of human lives and or the devastating damage to the landscape and human infrastructures. The winter of 2009/2010 in Madeira Island was characterized by several episodes of very intense precipitation (specially in December 2009 and February 2010) adding to a new record of accumulated precipitation since there are records in the island. In February two days are especially rainy with absolute records for the month of February (daily records since 1949): 111mm and 97mm on the 2nd and 20th respectively. The accumulated precipitation ended up with the terrible floods on the 20th of February causing the lost of dozens of human lives and hundreds of millions of Euros of losses The large precipitation occurrences either more intense precipitation in a short period or less intense precipitation during a larger period are sometimes the precursor of geological phenomena resulting in land movement, many times in the same or very near areas from previous episodes. Although flood episodes have a strong dependency in the topography and hydrological capacity of the terrains, the human intervention is also an enormously important factor, more specifically the anthropogenic factors such deforestation, dams, change of water fluxes, and impermeabilization of the terrain surface. The risk assessment of floods should be address based not only on the knowledge of the meteorological and hidrometeorological factors, such the accumulated precipitation and soil water balance but also in the river path and water amounts and well the surrounding geomorphology of the water basins. The current work is focused in the meteorological contribution for the floods occurrence episode of 2010 in the Madeira Island, specifically the climatic characterization of the 2009/2010 Winter with particular incidence on the days of the 2nd and 20th of February.

Re-fighting the 2nd Anglo-Boer War: historians in the trenches  

Directory of Open Access Journals (Sweden)

Full Text Available Some one hundred years ago, South Africa was tom apart by the 2nd Anglo- Boer War (1899-1902. The war was a colossal psychological experience fought at great expense: It cost Britain twenty-two thousand men and £223 million. The social, economic and political cost to South Africa was greater than the statistics immediately indicate: at least ten thousand fighting men in addition to the camp deaths, where a combination of indifference and incompetence resulted in the deaths of 27 927 Boers and at least 14 154 Black South Africans. Yet these numbers belie the consequences. It was easy for the British to 'forget' the pain of the war, which seemed so insignificant after the losses sustained in 1914-18. With a long history of far-off battles and foreign wars, the British casualties of the Anglo-Boer War became increasingly insignificant as opposed to the lesser numbers held in the collective Afrikaner mind. This impact may be stated somewhat more candidly in terms of the war participation ratio for the belligerent populations. After all, not all South Africans fought in uniform. For the Australian colonies these varied between 4½per thousand (New South Wales to 42.3 per thousand (Tasmania. New Zealand 8 per thousand, Britain 8½ per thousand: and Canada 12.3 per thousand; while in parts of South Africa this was perhaps as high as 900 per thousand. The deaths and high South African participation ratio, together with the unjustness of the war in the eyes of most Afrikaners, introduced bitterness, if not a hatred, which has cast long shadows upon twentieth-century South Africa.

Conference Report on the 2nd International Symposium on Lithium Applications for Fusion Devices  

Science.gov (United States)

The 2nd International Symposium on Lithium Applications for Fusion Devices (ISLA-2011) was held on 27-29 April 2011 at the Princeton Plasma Physics Laboratory (PPPL) with broad participation from the community working on aspects of lithium research for fusion energy development. This community is expanding rapidly in many areas including experiments in magnetic confinement devices and a variety of lithium test stands, theory and modeling and developing innovative approaches. Overall, 53 presentations were given representing 26 institutions from 10 countries. The latest experimental results from nine magnetic fusion devices were given in 24 presentations, from NSTX (PPPL, USA), LTX (PPPL, USA), FT-U (ENEA, Italy), T-11M (TRINITY, RF), T-10 (Kurchatov Institute, RF), TJ-II (CIEMAT, Spain), EAST (ASIPP, China), HT-7 (ASIPP, China), and RFX (Padova, Italy). Sessions were devoted to: I. Lithium in magnetic confinement experiments (facility overviews), II. Lithium in magnetic confinement experiments (topical issues), III. Special session on liquid lithium technology, IV. Lithium laboratory test stands, V. Lithium theory/modeling/comments, VI. Innovative lithium applications and VII. Panel discussion on lithium PFC viability in magnetic fusion reactors. There was notable participation from the fusion technology communities, including the IFE, IFMIF and TBM communities providing productive exchanges with the physics oriented magnetic confinement lithium research groups. It was agreed to continue future exchanges of ideas and data to help develop attractive liquid lithium solutions for very challenging magnetic fusion issues, such as development of a high heat flux steady-state divertor concept and acceptable plasma disruption mitigation techniques while improving plasma performance with lithium. The next workshop will be held at ENEA, Frascati, Italy in 2013.

Analysis of Harmonic Wave Generation in Nonlinear Oblique Crack Surface  

Energy Technology Data Exchange (ETDEWEB)

Based on the nonlinear spring model coupled with perturbation method, 2nd harmonic waves generated by oblique incident ultrasound on nonlinear crack interface were calculated and investigated. Reflected and transmitted waves from the interface were determined and analyzed at various angle of incidence for the cracks with different interfacial stiffness in order to estimate the 2nd harmonic generation of incident ultrasound. It was shown in computer simulation that the 2nd harmonic components changed much with the increase of incidence angle in both reflected and transmitted wave, but became very small when the incident angle approached toward 90 degree. It can be concluded that the 2nd harmonic component of reflected wave has a meaningful amplitude as much as the transmitted 2nd harmonic wave from partly closed crack.

Diva-Fit: A step-by-step manual for generating high-resolution graphs and histogram overlays of flow cytometry data obtained with FACSDiva software  

Directory of Open Access Journals (Sweden)

Full Text Available In recent years, flow cytometry has been revolutionized via the introduction of digital data acquisition and analysis tools that facilitate simultaneous investigation of ten or more parameters. At the same time, some data presentation tools offered by commercial suppliers have remained surprisingly “antiquated”. This leads to the ironic fact that high-quality data is often represented by poor-quality illustrations: namely pixelated plots. In particular, data obtained using FACSDiva software is frequently exported into figures as low-resolution pixel graphics resulting in low-quality images. Additionally, even the newest version, Diva_6.1.2, is still unable to generate histogram overlays, a popular and convincing tool for direct data comparison. We hereby present an easy and down-to-earth Diva-Figure-improvement toolbox (Diva-Fit, which facilitates the generation of high-resolution graphs based on data acquired with FACSDiva software. Moreover, Diva-Fit allows the easy removal of unwanted quadrant labels without impairing the quality of FACS plots. Finally, we show that Diva-Fit supports straightforward composition of histogram overlays. All software tools necessary are freely available. We believe that the proposed toolbox may be very useful for many researchers working with flow cytometry.

International Nuclear Information System (INIS)

The crystal, magnetic structures and physical properties of the double perovskite-type barium neodymium osmate Ba2NdOsO6 are investigated through powder X-ray and neutron diffraction, electrical conductivity, magnetic susceptibility, and specific heat measurements. The Rietveld analysis reveals that the Nd and Os ions are arranged with regularity over the six-coordinate B sites in a distorted perovskite ABO3 framework. The monoclinic crystal structure described by space group P21/n (tilt system a?a?c+) becomes more distorted with decreasing temperature from 300 K down to 2.5 K. This compound shows a long-range antiferromagnetic ordering of Os5+ below 65 K. An antiferromagnetic ordering of Nd3+ also occurs at lower temperatures (?20 K). The magnetic structure is of Type I and the magnetic moments of Nd3+ and Os5+ ions are in the same direction in the ab-plane. - Graphical Abstract: The Magnetic structure of Ba2NdOsO6 is of Type I, and the magnetic moments of the Nd3+ and Os5+ ions are in the same direction in the ab-plane. Highlights: ? Crystal structures of Ba2NdOsO6 are determined to be monoclinic below 300 K. ? Its electrical resistivity shows a Mott variable-range hopping behavior with localized carriers. ?

On possibility of low-threshold two-plasmon decay instability in 2nd harmonic ECRH experiments at toroidal devices  

Directory of Open Access Journals (Sweden)

Full Text Available The effects of the parametric decay of the 2nd harmonic X-mode into two short wave-length UH plasmons propagating in opposite directions is considered. The possibility of the absolute instability excitation is demonstrated in the case of the density profile possessing local maximum slightly exceeding the UH resonance value. The threshold of the absolute instability is shown to be substantially smaller than that provided by the standard theory for monotonous density profile.

International Nuclear Information System (INIS)

TiO2 and TiO2:Nd,Yb films were deposited by a doctor blade deposition technique from pastes prepared by a sol–gel process, and characterized by electron microscopy and spectroscopic techniques. Near infrared (NIR) photoluminescence (PL) properties upon 808 nm excitation were also examined. The rutile TiO2:Nd,Yb samples exhibited the strongest NIR PL signal. The relationship between the morphological properties, annealing temperature and the optical behavior of TiO2:Nd,Yb films is discussed. Furthermore, the study showed that hyperspectral imaging spectroscopy can be used as a rapid and nondestructive macroscopic characterization technique for the identification of spectral features and evaluation of luminescent surfaces of oxides. -- Highlights: ? Films and powders of Nd and Yb-doped titania have been synthesized. ? Three modifications (anatase, rutile and Degussa P25) have been studied. ? The NIR photoluminescence properties were studied by hyperspectral imaging. ? Emission at 978, 1008, 1029, 1064 and 1339 nm was obtained. ?

Dependence of cosmic ray solar daily variation (1st, 2nd and 3rd) on heliomagnetic polarity reversals  

International Nuclear Information System (INIS)

Using 696 station-years of neutron monitor data during the period of 1964-1983 and those from muon telescopes at surface and underground stations, a long term variation of cosmic ray solar daily variations (1st, 2nd and 3rd) has been analysed in order to study its dependence on the heliomagnetic polarity reversals. It is found that 1st, 2nd and 3rd harmonic variations show respectively counter clockwise phase shifts on the harmonic dial for the transition from the Negative to the Positive polarity state. The polarity state is defined as 'Positive' ('Negative') when the interplanetary magnetic field (IMF) is away (toward) in the Northern Hemisphere and toward (away) in the Southern Hemisphere. It is demonstrated that these phase shifts cannot be explained by one-dimensional diffusion of the pitch angle distribution along the IMF-axis, such as the one presented by Bieber and Pomerantz, but can be explained by three-dimensional treatment of the cosmic ray diffusion-convection in space developed by Munakata and Nagashima in considering the drift effect in the heliosphere pointed out by Jokipii et al. According to the theory, the rigidity dependence of the observed phase shift of the 2nd harmonic variation suggests that the power exponent of the rigidity spectrum of the cosmic ray mean free path is less than unity at least in a rigidity region of about one to several tens GV.

Comparison of elution efficiency of 99Mo/99mTc generator using theoretical and a free web based software method  

International Nuclear Information System (INIS)

Full text: Generator is constructed on the principle of decay growth relationship between a long lived parent radionuclide and short lived daughter radionuclide. Difference in chemical properties of daughter and parent radionuclide helps in efficient separation of the two radionuclides. Aim and Objectives: The present study was designed to calculate the elution efficiency of the generator using the traditional formula based method and free web based software method. Materials and Methods: 99Mo/99mTc MON.TEK (Monrol, Gebze) generator and sterile 0.9% NaCl vial and vacuum vial in the lead shield were used for the elution. A new 99Mo/99mTc generator (calibrated activity 30GBq) calibrated for thursday was received on monday morning in our department. Generator was placed behind lead bricks in fume hood. The rubber plugs of both vacuum and 0.9% NaCl vial were wiped with 70% isopropyl alcohol swabs. Vacuum vial placed inside the lead shield was inserted in the vacuum position simultaneously 10 ml NaCl vial was inserted in the second slot. After 1-2 min vacuum vial was removed without moving the emptied 0.9%NaCl vial. The vacuum slot was covered with another sterile vial to maintain sterility. The RAC was measured in the calibrated dose calibrator (Capintec, 15 CRC). The elution efficiency was calculated theoretically and using free web based software (Apache Web server (www.apache.org) and PHP (www.php.net). Web site of the Italian Association of Nuclear Medicine and Molecular Imaging (www.aimn.it). Results: The mean elution efficiency calculated by theoretical method was 93.95% +0.61. The mean elution efficiency as calculated by the software was 92.85% + 0.89. There was no statistical difference in both the methods. Conclusion: The free web based software provides precise and reproducible results and thus saves time and mathematical calculation steps. This enables a rational use of available activity and also enabling a selection of the type and number of procedures to perform in a busy nuclear medicine department

Elementary processes in combustion and sooting of coal derived fuels. Progress report: 2nd year, 2nd quarter, November 10, 1983-February 9, 1984. [:CH/sub 2/  

Energy Technology Data Exchange (ETDEWEB)

Accomplishments are briefly discussed for the following tasks: (1) reactivity of aromatics - intermediates in combustion and soot formation; (2) generation of ions for reaction studies; and (3) chemistry of C/sub 4/ diradicals. As a prototype for radical attack on aromatics, a process important for the combustion and sooting of aromatic-rich synthetic fuels, the reaction of :CH/sub 2/ and benzene was examined. A mixture of diazomethane (CH/sub 2/N/sub 2/) and benzene was expanded through the free nozzle which was heated to 170 +- 10/sup 0/C. Diazomethane decomposes to :CH/sub 2/ and N/sub 2/ and a pulsed tunable laser was used to search for reaction products by laser induced fluorescence. The reaction is believed to lead to toluene through norcaradiene and cycloheptatriene species. In these preliminary studies neither were found but the small reaction yield was the problem. This reaction will be repeated using the photodecomposition of ketene, CH/sub 2/CO, to generate the :CH/sub 2/. For task 2, we have been able to elucidate the pathways to ion generation in multiphoton ionization and are able to produce the C/sub 6/H/sub 5//sup +/ and C/sub 5/H/sub 4//sup +//C/sub 5/H/sub 3//sup +/ species for reaction studies. Work is continuing on the chemistry of radical intermediates in the combustion of aromatics for task 3. The C/sub 4/H/sub 8/ diradical decomposes to two ethylenes in quantitative yields as determined by gas phase high-resolution ir spectroscopy.

Early elementary schooling in 2nd and 3rd grades (ages 7-9) is an important period for the acquisition and mastery of basic mathematical skills. Yet, we know very little about neurodevelopmental changes that might occur over a year of schooling. Here we examine behavioral and neurodevelopmental changes underlying arithmetic problem solving in a well-matched group of 2nd (n = 45) and 3rd (n = 45) grade children.

FOREWORD: 2nd International Workshop on New Computational Methods for Inverse Problems (NCMIP 2012)  

Science.gov (United States)

Conference logo This volume of Journal of Physics: Conference Series is dedicated to the scientific contributions presented during the 2nd International Workshop on New Computational Methods for Inverse Problems, (NCMIP 2012). This workshop took place at Ecole Normale Supérieure de Cachan, in Cachan, France, on 15 May 2012, at the initiative of Institut Farman. The first edition of NCMIP also took place in Cachan, France, within the scope of the ValueTools Conference, in May 2011 (http://www.ncmip.org/2011/). The NCMIP Workshop focused on recent advances in the resolution of inverse problems. Indeed inverse problems appear in numerous scientific areas such as geophysics, biological and medical imaging, material and structure characterization, electrical, mechanical and civil engineering, and finance. The resolution of inverse problems consists of estimating the parameters of the observed system or structure from data collected by an instrumental sensing or imaging device. Its success firstly requires the collection of relevant observation data. It also requires accurate models describing the physical interactions between the instrumental device and the observed system, as well as the intrinsic properties of the solution itself. Finally, it requires the design of robust, accurate and efficient inversion algorithms. Advanced sensor arrays and imaging devices provide high rate and high volume data; in this context, the efficient resolution of the inverse problem requires the joint development of new models and inversion methods, taking computational and implementation aspects into account. During this one-day workshop, researchers had the opportunity to bring to light and share new techniques and results in the field of inverse problems. The topics of the workshop were: algorithms and computational aspects of inversion, Bayesian estimation, kernel methods, learning methods, convex optimization, free discontinuity problems, metamodels, proper orthogonal decomposition, reduced models for the inversion, non-linear inverse scattering, image reconstruction and restoration, applications (bio-medical imaging, non-destructive evaluation etc). NCMIP 2012 was a one-day workshop. Each of the submitted papers was reviewed by 2 to 4 reviewers. Among the accepted papers, there are 8 oral presentations and 5 posters. Three international speakers were invited for a long talk. This second edition attracted 60 registered attendees in May 2012. NCMIP 2012 was supported by Institut Farman (ENS Cachan) and endorsed by the following French research networks (GDR ISIS, GDR Ondes, GDR MOA, GDR MSPC). The program committee acknowledges the following laboratories CMLA, LMT, LSV, LURPA, SATIE, as well as DIGITEO Network.

Development of Hydrologic Characterization Technology of Fault Zones -- Phase I, 2nd Report  

Energy Technology Data Exchange (ETDEWEB)

This is the year-end report of the 2nd year of the NUMO-LBNL collaborative project: Development of Hydrologic Characterization Technology of Fault Zones under NUMO-DOE/LBNL collaboration agreement, the task description of which can be found in the Appendix 3. Literature survey of published information on the relationship between geologic and hydrologic characteristics of faults was conducted. The survey concluded that it may be possible to classify faults by indicators based on various geometric and geologic attributes that may indirectly relate to the hydrologic property of faults. Analysis of existing information on the Wildcat Fault and its surrounding geology was performed. The Wildcat Fault is thought to be a strike-slip fault with a thrust component that runs along the eastern boundary of the Lawrence Berkeley National Laboratory. It is believed to be part of the Hayward Fault system but is considered inactive. Three trenches were excavated at carefully selected locations mainly based on the information from the past investigative work inside the LBNL property. At least one fault was encountered in all three trenches. Detailed trench mapping was conducted by CRIEPI (Central Research Institute for Electric Power Industries) and LBNL scientists. Some intriguing and puzzling discoveries were made that may contradict with the published work in the past. Predictions are made regarding the hydrologic property of the Wildcat Fault based on the analysis of fault structure. Preliminary conceptual models of the Wildcat Fault were proposed. The Wildcat Fault appears to have multiple splays and some low angled faults may be part of the flower structure. In parallel, surface geophysical investigations were conducted using electrical resistivity survey and seismic reflection profiling along three lines on the north and south of the LBNL site. Because of the steep terrain, it was difficult to find optimum locations for survey lines as it is desirable for them to be as straight as possible. One interpretation suggests that the Wildcat Fault is westerly dipping. This could imply that the Wildcat Fault may merge with the Hayward Fault at depth. However, due to the complex geology of the Berkeley Hills, multiple interpretations of the geophysical surveys are possible. iv An effort to construct a 3D GIS model is under way. The model will be used not so much for visualization of the existing data because only surface data are available thus far, but to conduct investigation of possible abutment relations of the buried formations offset by the fault. A 3D model would be useful to conduct 'what if' scenario testing to aid the selection of borehole drilling locations and configurations. Based on the information available thus far, a preliminary plan for borehole drilling is outlined. The basic strategy is to first drill boreholes on both sides of the fault without penetrating it. Borehole tests will be conducted in these boreholes to estimate the property of the fault. Possibly a slanted borehole will be drilled later to intersect the fault to confirm the findings from the boreholes that do not intersect the fault. Finally, the lessons learned from conducting the trenching and geophysical surveys are listed. It is believed that these lessons will be invaluable information for NUMO when it conducts preliminary investigations at yet-to-be selected candidate sites in Japan.

Development of Hydrologic Characterization Technology of Fault Zones: Phase I, 2nd Report  

International Nuclear Information System (INIS)

This is the year-end report of the 2nd year of the NUMO-LBNL collaborative project: Development of Hydrologic Characterization Technology of Fault Zones under NUMO-DOE/LBNL collaboration agreement, the task description of which can be found in the Appendix 3. Literature survey of published information on the relationship between geologic and hydrologic characteristics of faults was conducted. The survey concluded that it may be possible to classify faults by indicators based on various geometric and geologic attributes that may indirectly relate to the hydrologic property of faults. Analysis of existing information on the Wildcat Fault and its surrounding geology was performed. The Wildcat Fault is thought to be a strike-slip fault with a thrust component that runs along the eastern boundary of the Lawrence Berkeley National Laboratory. It is believed to be part of the Hayward Fault system but is considered inactive. Three trenches were excavated at carefully selected locations mainly based on the information from the past investigative work inside the LBNL property. At least one fault was encountered in all three trenches. Detailed trench mapping was conducted by CRIEPI (Central Research Institute for Electric Power Industries) and LBNL scientists. Some intriguing and puzzling discoveries were made that may contradict with the published work in the past. Predictions are made regarding the hydrologic property of the Wildcat Fault based on the analysis of fault structure. Preliminary conceptual models of the Wildcat Fault were proposed. The Wildcat Fault appears to have multiple splays and some low angled faults may be part of the flower structure. In parallel, surface geophysical investigations were conducted using electrical resistivity survey and seismic reflection profiling along three lines on the north and south of the LBNL site. Because of the steep terrain, it was difficult to find optimum locations for survey lines as it is desirable for them to be as straight as possible. One interpretation suggests that the Wildcat Fault is westerly dipping. This could imply that the Wildcat Fault may merge with the Hayward Fault at depth. However, due to the complex geology of the Berkeley Hills, multiple interpretations of the geophysical surveys are possible. iv An effort to construct a 3D GIS model is under way. The model will be used not so much for visualization of the existing data because only surface data are available thus far, but to conduct investigation of possible abutment relations of the buried formations offset by the fault. A 3D model would be useful to conduct 'what if' scenario testing to aid the selection of borehole drilling locations and configurations. Based on the information available thus far, a preliminary plan for borehole drilling is outlined. The basic strategy is to first drill boreholes on both sides of the fault without penetrating it. Borehole tests will be conducted in these boreholes to estimate the property of the fault. Possibly a slanted borehole will be drilled later to intersect the fault to confirm the findings from the boreholes that do not intersect the fault. Finally, the lessons learned from conducting the trenching and geophysical surveys are listed. It is believed that these lessons will be invaluable information for NUMO when it conducts preliminary investigations at yet-to-be selected candidate sites in Japan.

Transient and equilibrium cycle characteristics on Paks uprated power units with 2nd generation of Gadolinia fuel  

International Nuclear Information System (INIS)

A power up rating project actually in progress on PAKS NPP units in Hungary. Nominal power of Unit 4 and 1 has already increased to 1485 MWt h (500 MW e), it is the 108% of former nominal power. In order to provide economic fuel cycle on up rated power, Paks tends to introduce higher enriched fuel. The fuel has modified geometry offered by fuel vendor, the pin wise enrichment profile is slightly modified according to Paks requirements. Actually the safety analysis works of modified fuel introduction are going on. In frame of this work the transient cycle containing 'old' and modified fuel and the new equilibrium cycles are determined. The main features of transient and equilibrium cycles are introduced in this report. The calculations has been made by modified C-PORCA code taking into account different length of new and old fuel. The cross section libraries are prepared by HELIOS (Authors)

The 2nd to 4th digit ratio (2D:4D) and eating disorder diagnosis in women  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Eating disorders are more common in females than in males and are believed to be caused, in part, by biological and hormonal factors. Digit ratio or 2D:4D (the ratio of the 2nd to the 4th digit) is considered to be a proxy for prenatal testosterone (PT) and prenatal oestrogen (PE) exposure. However, how 2D:4D may be related to type of eating pathology is unknown. The relationship between 2D:4D and eating disorder diagnosis was investigated in recovered and currently eating disordered (n=31) a...

Investigations on layered perovskites: Na_2Nd_2Ti_3O_1_0, H_2Nd_2Ti_3O_1_0 and Nd_2Ti_3O_9?  

International Nuclear Information System (INIS)

The structure of the layered perovskite Na_2Nd_2Ti_3O_1_0 was investigated by refining X-ray powder diffraction data using the Rietveld method. The Nd"3"+ cation is located in the intra-slab perovskite site and the Na"+ cation in the interlayer space. Acid exchange of the potassium homologous compound leads to the formation of H_2Nd_2Ti_3O_1_0, xH_2O. Prior to condensation at 900 C, the thermolysis of this solid acid yields an intermediate phase which, despite the total removal of water, retains the layered structure from 600 C to 850 C. The thermal evolution of the protonated form was studied by thermal analysis and crystallographic techniques and was found to exhibit two main steps. The first corresponds to the removal of water, which is complete at 600 C, and results in an intermediate phase containing five-coordinated titanium cations and a statistical distribution of Nd"3"+ in the available intra- and interslab sites. The second step can be considered as a complex condensation reaction leading to a 3D-cation defective perovskite. (orig.)

Sequence comparative analysis using networks: software for evaluating de novo transcript assembly from next-generation sequencing.  

Science.gov (United States)

DNA sequencing technology is becoming more accessible to a variety of researchers as costs continue to decline. As researchers begin to sequence novel transcriptomes, most of these data sets lack a reference genome and will have to rely on de novo assemblers. Making comparisons across assemblies can be difficult: each program has its strengths and weaknesses, and no tool exists to comparatively evaluate these data sets. We developed software in R, called Sequence Comparative Analysis using Networks (SCAN), to perform statistical comparisons between distinct assemblies. SCAN uses a reference data set to identify the most accurate de novo assembly and the "good" transcripts in the user's data. We tested SCAN on three publicly available transcriptomes, each assembled using three assembly programs. Moreover, we sequenced the transcriptome of the oomycete Achlya hypogyna and compared de novo assemblies from Velvet, ABySS, and the CLC Genomics Workbench assembly algorithms. One thousand one hundred twenty-eight of the CLC transcripts were statistically similar to the reference, compared with 49 of the Velvet transcripts and 937 of the ABySS transcripts. SCAN's strength is providing statistical support for transcript assemblies in a biological context. However, SCAN is designed to compare distinct node sets in networks, therefore it can also easily be extended to perform statistical comparisons on any network graph regardless of what the nodes represent.

Conceptual design and optimization of a 1-1/2 generation PFBC plant task 14. Topical report  

Energy Technology Data Exchange (ETDEWEB)

The economics and performance of advanced pressurized fluidized bed (PFBC) cycles developed for utility applications during the last 10 years (especially the 2nd-Generation PFBC cycle) are projected to be favorable compared to conventional pulverized coal power plants. However, the improved economics of 2nd-Generation PFBC cycles are accompanied by the perception of increased technological risk related to the pressurized carbonizer and its associated gas cleanup systems. A PFBC cycle that removed the uncertainties of the carbonizer while retaining the high efficiency and low cost of a 2nd-Generation PFBC cycle could improve the prospects for early commercialization and pave the way for the introduction of the complete 2nd-Generation PFBC cycle at some later date. One such arrangement is a PFBC cycle with natural gas topping combustion, referred to as the 1.5-Generation PFBC cycle. This cycle combines the advantages of the 2nd-Generation PFBC plant with the reduced risk associated with a gas turbine burning natural gas, and can potentially be part of a phased approach leading to the commercialization of utility 2nd-Generation PFBC cycles. The 1.5-Generation PFBC may also introduce other advantages over the more complicated 2nd-Generation PFBC system. This report describes the technical and economic evaluation of 1.5-Generation PFBC cycles for utility or industrial power generation.

Determination of Conceptions of Secondary 10th Grade Students About Torque, Angular Momentum and Kepler’s 2nd Law  

Directory of Open Access Journals (Sweden)

Full Text Available Prior knowledge that students have can be compatible with scientific facts or it can be a learning disability different from the scientific facts. So it is important to reveal students' prior knowledge and to determine their ideas that are not compatible with scientific information. In this study, it has been aimed to reveal the prior knowledge of 133 tenth grade students about torque, conservation of angular momentum and Kepler's 2nd law. Students taking place in the sample have not taken formal education about these concepts yet and their ideas may be naive. The students have been asked three open-ended questions whose study of validity and reliability has been carried out. While it is seen that students gave answers consistent with the scientific facts about the torque concept, none of the answers given by students about the conservation of angular momentum and Kepler's 2nd law is included in the category of scientific answer. Students have been encountered the most common type of alternative answers for both of these concepts. In the teaching of this concept and law, students' prior knowledge conflicting with the scientific ideas should be considered, that is to say, teaching should be organized to include conceptual change.

COTS software selection process.  

Energy Technology Data Exchange (ETDEWEB)

Today's need for rapid software development has generated a great interest in employing Commercial-Off-The-Shelf (COTS) software products as a way of managing cost, developing time, and effort. With an abundance of COTS software packages to choose from, the problem now is how to systematically evaluate, rank, and select a COTS product that best meets the software project requirements and at the same time can leverage off the current corporate information technology architectural environment. This paper describes a systematic process for decision support in evaluating and ranking COTS software. Performed right after the requirements analysis, this process provides the evaluators with more concise, structural, and step-by-step activities for determining the best COTS software product with manageable risk. In addition, the process is presented in phases that are flexible to allow for customization or tailoring to meet various projects' requirements.

Software Testing  

Directory of Open Access Journals (Sweden)

Full Text Available Software goes through a cycle of software development stages. A software is envisioned, created, evaluated, fixed and then put to use. To run any software consistently without any failure/bug/error, the most important step is to test the software. This paper points various types of software testing(manual and automation, various software testing techniques like black box, white box, gray box, sanity, functional testing etc. and software test life cycle models (V-model and W-model. This paper tries to solve the misconceptions of those who think that testing is to be done only after the coding phase, but in reality it is to be associated with each and every phase of software life cycle models.

Early prediction for necessity of 2nd I-131 ablation therapy with serum thyroglobulin levels in patients with differentiated thyroid cancer  

International Nuclear Information System (INIS)

The aim of our study was to evaluate the predictive value of serum thyroglobulin levels, measured at preoperative status and just before 1st I-131 ablation therapy with high serum TSH, for necessity of 2nd I-131 ablation therapy in differentiated thyroid cancer patients. 111 patients with DTC who underwent total or near total thyroidectomy followed by immediate I-131 ablation therapy, were enrolled in this study. TSH, Tg and anti-Tg autoantibody were measured before thyroidectomy (TSHpreop, Tgpreop and Anti-Tgpreop) and just before 1st I-131 ablation therapy (TSHabl, Tgabl and Anti-Tgabl). All TSHabl levels were above 30mU/liter, ATg [(Tgpreop-Tgabl)X100/(Tgpreop)] was calculated. 29 patients(26.1%, 29/111) had to receive 2nd I-131 ablation therapy. Of 70 patients whose Tgabl were under 10 ng/ml, only 11 patients had received 2nd I-131 ablation therapy (15.7%). Patients with Tgabl greater than or equal to 10 ng/ml had received 2nd I-131 ablation therapy (18/41, 43.9%) than patients with lower Tgabl level. There was a disparity of necessity of 2nd I-131 ablation therapy between two groups(Tgabl <10 ng/ml and Tgabl =10 ng/ml, two by two /2 test p=0.0016). Of 41 patients with Tgabl greater than or equal to 10 ng/ml, 19 patients showed increased Tg levels (ATg<0). Patients with negative ATg and Tgabl greater than or equal to 10 ng/ml showed a strikingly high necessity of 2nd I-131 ablation therapy (11/19, 57.9%). There was also a significant disparity of necessity of 2nd I-131 ablation therapy between two groups(ATg<0 + Tgabl =10 ng/ml and the others, two by two /2 test, p=0.0012). These results suggest that high Tgabl level just before 1st I-131 ablation therapy can forecast the necessity of 2nd I-131 ablation therapy. Moreover, Difference of Tg level between preoperative status and just before 1st I-131 ablation therapy could also suggest necessity of 2nd I-131 ablation therapy at early period of DTC patients surveillance

CaF2:Mn thermoluminescence: a single glow peak not described by 1st or 2nd order kinetics  

International Nuclear Information System (INIS)

The thermoluminescence (TL) of CaF2:Mn has been studied using photon counting and digital recording. For doses of 10 rad or less the TL glow curves appear to consist of a single glow peak. However, there are indications - which are pronounced at larger doses - that one additional low intensity peak (area less than or equal to one percent) is superimposed on each side of the central peak. The intense peak is not described by 1st or 2nd order kinetics but is well described by the more general kinetics from which these kinetics are derived. These observations, and the results of additional kinetic analysis, demonstrate that retrapping is not negligible and may include all three peaks. In such systems, which are likely to include other dosimeter materials and minerals, peak height will not increase linearly with dose; an important factor for dosimetry and dating applications

Use of 2nd and 3rd Level Correlation Analysis for Studying Degradation in Polycrystalline Thin-Film Solar Cells  

Energy Technology Data Exchange (ETDEWEB)

The correlation of stress-induced changes in the performance of laboratory-made CdTe solar cells with various 2nd and 3rd level metrics is discussed. The overall behavior of aggregated data showing how cell efficiency changes as a function of open-circuit voltage (Voc), short-circuit current density (Jsc), and fill factor (FF) is explained using a two-diode, PSpice model in which degradation is simulated by systematically changing model parameters. FF shows the highest correlation with performance during stress, and is subsequently shown to be most affected by shunt resistance, recombination and in some cases voltage-dependent collection. Large decreases in Jsc as well as increasing rates of Voc degradation are related to voltage-dependent collection effects and catastrophic shunting respectively. Large decreases in Voc in the absence of catastrophic shunting are attributed to increased recombination. The relevance of capacitance-derived data correlated with both Voc and FF is discussed.

[Near-infrared fluorescence and energy transfer in Sr2SiO4 : Eu2+, Nd3+].  

Science.gov (United States)

Sr2 SiO4 : Eu2+ , Nd3+ was synthesized by solid state synthesis method, and the sensitization of Nd3+ near-infrared luminescence by Eu2+ was investigated. The characteristic near-infrared luminescence of Nd2+ in Sr2 SiO4 matrix was greatly enhanced by co-doping of Eu2+. The mechanism of energy transfer from Eu2+ to Nd3+ was analyzed through investigation of fluorescence excitation and emission spectra, and fluorescence lifetime. Excited Eu2+ (II) transfers energy effectively to Nd3+ through non-radiative energy transfer process in Sr2SiO4, resulting in greatly enhanced near-infrared luminescence of Nd3+, while sensitization of Nd3+ by Eu2+ (I) was achieved by the way of Eu2+ (II).

[Optimization of the Barron ligature treatment of 2nd and 3rd-degree hemorrhoids using a therapeutic troika].  

Science.gov (United States)

Due to the fact that the intensity of haemorrhoidal complaints may rapidly change, also numerous therapeutic approaches of minor effectiveness are considered a helpful remedy. However, the advantage of the Barron-ligature is not seriously doubted. By placing it correctly at the insensitive distal rectum, haemorrhoidal operations are only necessary in very advanced stages. Can the Barron ligature be optimized even more? Three patient groups consisting of 120 patients with 2nd degree haemorrhoids who were simultaneously treated by anal dilation using an appropriate lubricant for the anal dilator, were compared with each other in a randomized, open, placebo-controlled study conducted in two centres. In these groups treatment consisted of: rubber-band ligature alone rubber-band ligature and anal dilator and Kamillosan ointment rubber-band ligature and anal dilator and vaseline The observation period comprised six weeks. Every two weeks a check was made. Assessment criteria were: light-red haemorrhage, itching, oozing, sensation of incomplete evacuation, nodal prolapse and slight staining after defecation The pressure ratios of the closing apparatus were investigated at the beginning and end of the study. The group who had been treated with rubber-band ligature, anal dilator and Kamillosan ointment showed the best results. By simultaneously applying the rubber-band ligature, anal dilator and Kamillosan ointment as a lubricant, significantly better results could be obtained. The findings are based on a former retrospective study carried out in 500 patients with 2nd degree haemorrhoids. In this study by applying the anal dilator and Kamillosan ointment, the number of treatments could significantly be reduced from 5.95 to 4.2 and the number of necessary ligatures from 3.8 to 2.76 which, also from the economic point of view, was favourable.

Generation of a vector of nodal forces produced by loads pre-set by the arbitrary sculpted surface designated for universal stress analysis software ?????????? ???????????? ??????? ??????? ??? ?? ????????, ???????? ???????????? ???????????????? ????????????, ??? ????????????? ?????? ???????????? ???????  

Directory of Open Access Journals (Sweden)

Full Text Available The subject matter of the article represents the concept of a vector of nodal forces produced by loads pre-set by the arbitrary sculpted surface. The concept in question may be integrated into engineering CAD systems in the capacity of a preprocessor. Pursuant to the proposed methodology, the initial surface load represents a geometric object pre-set as a selection of standard graphic primitives. This technology is easy to use if the pre-processing constituent of the strength analysis system operates within CAD media. Multi-factor strength-related problems were resolved by Department of Computer-Aided Design of Moscow State University of Roads. Researchers have developed and tested KATRAN open architecture strength analysis software programme that may be integrated into AutoCAD processor. A user may select the surface accommodating any simulated arbitrary load; further, a point of the pre-set load intensity specified in the Distributed Load Q field of interface window Distributed Loads, and the point of zero intensity load are to be specified. The above source data are used to calculate the scale coefficient of transition from linear distances to the real value of the load intensity generated within the coordinate surface. The point of zero load intensity represents a virtual plane of zero distributed load values. The proposed software designated for the conversion of arbitrary distributed loads into the nodal load is compact; therefore, it may be integrated into modules capable of exporting the nodal load into other systems of strength analysis, though functioning as a problem-oriented geometrical utility of AutoCAD.???????? ????????? ???????????? ??????? ??????? ??? ?? ????????, ???????? ???????????? ???????????????? ????????????, ??? ???????? ???????????? ???????, ???????????? ? ???????? ????????????? ??????????

Multi-atom resonant photoemission and the development of next-generation software and high-speed detectors for electron spectroscopy  

International Nuclear Information System (INIS)

This dissertation has involved the exploration of a new effect in photoelectron emission, multi-atom resonant photoemission (MARPE), as well as the development of new software, data analysis techniques, and detectors of general use in such research. We present experimental and theoretical results related to MARPE, in which the photoelectron intensity from a core level on one atom is influenced by a core-level absorption resonance on another. We point out that some of our and others prior experimental data has been strongly influenced by detector non-linearity and that the effects seen in new corrected data are smaller and of different form. Corrected data for the MnO(001) system with resonance between the O 1s and Mn 2p energy levels are found to be well described by an extension of well-known intraatomic resonant photoemission theory to the interatomic case, provided that interactions beyond the usual second-order Kramers-Heisenberg treatment are included. This theory is also found to simplify under certain conditions so as to yield results equivalent to a classical x-ray optical approach, with the latter providing an accurate and alternative, although less detailed and general, physical picture of these effects. Possible future applications of MARPE as a new probe of near-neighbor identities and bonding and its relationship to other known effects are also discussed. We also consider in detail specially written data acquisition software that has been used for most of the measurements reported here. This software has been used with an existing experimental system to develop the method of detector characterization and then data correction required for the work described above. The development of a next generation one-dimensional, high-speed, electron detector is also discussed. Our goal has been to design, build and test a prototype high-performance, one-dimensional pulse-counting detector that represents a significant advancement in detector technology and is well matched to modern high-brightness synchrotrons radiation sources and high-transmission electron-energy analyzers as typically used in photoelectron spectroscopy experiments. The general design of the detector and the results of initial tests are discussed and the acquisition of photoelectron spectra with the first test detector is described

Development of a radioactive waste treatment equipment utilizing microwave heating, 2nd report  

International Nuclear Information System (INIS)

The objective of the present study is to establish an incineration technique utilizing microwave heating which enables a high volume reduction of spent ion-exchange resins and filtering media generated at nuclear facilities. The past three years from 1982 to 1985, with the financial aid from the Agency of Science and Technology, brought a great and rapid progress to this project when the heating technique was switched from direct microwave heating to indirect heating by employing a bed of beads of silicon carbide. This material was also used to build a secondary furnace, walls and roster bars, to treat the obnoxious gases and soot arising in the primary incineration process by the radiating heat of this material heated to above 1000 deg C again by microwave energy, but not by the originarily applied direct plasma torch combustion. The incinerator and the secondary furnace were integrated into one unit as the principal treating equipment. This novel approach made possible a well stabilized continuous incineration operation. Further, developmental efforts toward industrial applications were made by setting up a pilot plant with microwave generators, 2 sets of 5 kW of 2450 MHz and 1 set of 25 kW of 915 MHz, and tests were carried out to prove remarkably high volume reduction capability well above roughly 200 on weight basis. For hot test runs, a one - tenth scale pilot test setup was installed at the TOKAI Laboratory of Japan Atmic Energy Research Institute and tested with materials spiked with radioisotopes and also with spent ion-exchange resins stored there. Very satisfactory results were obtained in these proving tests to show the efficient capability of high volume reduction treatment of otherwise stable radioactive waste materials such as spent ion-exchange resins.

Software Engineering” is Engineering  

Directory of Open Access Journals (Sweden)

Full Text Available Determine that "Software Engineering" is engineering, is an issue that generates discussion in many universities in which, by decades, computer science programs have used the term to describe individual courses and claim it as part of their discipline. However, some engineering faculties demand it as a new and necessary specialty between traditional engineering disciplines. This article analyzed the differences between Computer Science and "Software Engineering" as engineering and is argued the necessity of a program in this last that follow the traditional engineering approach looking for a professional formation of software engineers.

FragVLib a free database mining software for generating "Fragment-based Virtual Library" using pocket similarity search of ligand-receptor complexes  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background With the exponential increase in the number of available ligand-receptor complexes, researchers are becoming more dedicated to mine these complexes to facilitate the drug design and development process. Therefore, we present FragVLib, free software which is developed as a tool for performing similarity search across database(s of ligand-receptor complexes for identifying binding pockets which are similar to that of a target receptor. Results The search is based on 3D-geometric and chemical similarity of the atoms forming the binding pocket. For each match identified, the ligand's fragment(s corresponding to that binding pocket are extracted, thus, forming a virtual library of fragments (FragVLib that is useful for structure-based drug design. Conclusions An efficient algorithm is implemented in FragVLib to facilitate the pocket similarity search. The resulting fragments can be used for structure-based drug design tools such as Fragment-Based Lead Discovery (FBLD. They can also be used for finding bioisosteres and as an idea generator.

Dielectric properties of [Ca1-x(Li1/2Nd1/2)x]1-yZnyTiO3 ceramics at microwave frequencies  

International Nuclear Information System (INIS)

Dielectric properties of Ca1-x(Li1/2Nd1/2)xTiO3 (0.0?x?0.6, CLNT) and [Ca0.6(Li1/2Nd1/2)0.4]1-yZnyTiO3 (0.5?y?1.0, CLNZT) ceramics were investigated at 4-10 GHz. For the CLNT system, a single perovskite phase was detected in the entire composition range. The dielectric constants (K), and the temperature coefficients of the resonant frequency (TCF) were dependent on the B-site bond valence. Qf value decreases with the increase in (Li1/2Nd1/2)TiO3 content (x) due to a decrease in grain size. For the CLNZT system, Qf value and TCF were improved with Zn content (y) due to the formation of Zn2TiO4. Typically, K of 47, Qf of 13000 GHz, TCF of 14 ppm per deg. C were obtained for [Ca0.6(Li1/2Nd1/2)0.4]0.4Zn0.6TiO3 sintered at 1150 deg. C for 4 h

A software engineering process for safety-critical software application  

International Nuclear Information System (INIS)

Application of computer software to safety-critical systems in on the increase. To be successful, the software must be designed and constructed to meet the functional and performance requirements of the system. For safety reason, the software must be demonstrated not only to meet these requirements, but also to operate safely as a component within the system. For longer-term cost consideration, the software must be designed and structured to ease future maintenance and modifications. This paper presents a software engineering process for the production of safety-critical software for a nuclear power plant. The presentation is expository in nature of a viable high quality safety-critical software development. It is based on the ideas of a rational design process and on the experience of the adaptation of such process in the production of the safety-critical software for the shutdown system number two of Wolsung 2, 3 and 4 nuclear power generation plants. This process is significantly different from a conventional process in terms of rigorous software development phases and software design techniques, The process covers documentation, design, verification and testing using mathematically precise notations and highly reviewable tabular format to specify software requirements and software requirements and software requirements and code against software design using static analysis. The software engineering process described in this paper applies the principle of information-hiding decomposition in software design using a modular design technique so that when a change is required or an error is detected, the affected scope can be readily and confidently located. it also facilitates a sense of high degree of confidence in the 'correctness' of the software production, and provides a relatively simple and straightforward code implementation effort. 1 figs., 10 refs.

Effect of CO2, Nd:YAG, and Er:YAG lasers on dentin and pulp tissues in dogs  

Science.gov (United States)

Although there has been interest in lasers in dentistry since lasers were first developed in the early 1960's, this interest was limited until recently. Over the past five years there has been a flurry of interest to find the most effective wavelength and parameters of treatment. With this interest has come clinical and experimental reports. This project is a pilot study to investigate laser effects on dogs teeth. Multiple teeth from 2 dogs (n equals 40) were treated using either a CO2, Nd:YAG, or an Er:YAG laser, or slow-speed rotary instrumentation. One dog died after treatment and was not used in this study. The second dog was sacrificed four days after treatment with the lasers and the teeth were decalcified and processed for light microscopy. The dentin and pulpal tissues were then evaluated for changes from their normal histologic patterns. The purpose of this study was to first determine if the dog would be a good model for in-vivo histologic testing of lasers and second to evaluate the histologic effects of different lasers on dog's teeth. Our findings suggest that each laser causes a different degree of effect to the treated teeth. The specifics of these effects are discussed herein.

Explicit formulas for 2nd-order driving terms due to sextupoles and chromatic effects of quadrupoles.  

Energy Technology Data Exchange (ETDEWEB)

Optimization of nonlinear driving terms have become a useful tool for designing storage rings, especially modern light sources where the strong nonlinearity is dominated by the large chromatic effects of quadrupoles and strong sextupoles for chromaticity control. The Lie algebraic method is well known for computing such driving terms. However, it appears that there was a lack of explicit formulas in the public domain for such computation, resulting in uncertainty and/or inconsistency in widely used codes. This note presents explicit formulas for driving terms due to sextupoles and chromatic effects of quadrupoles, which can be considered as thin elements. The computation is accurate to the 4th-order Hamiltonian and 2nd-order in terms of magnet parameters. The results given here are the same as the APS internal note AOP-TN-2009-020. This internal nte has been revised and published here as a Light Source Note in order to get this information into the public domain, since both ELEGANT and OPA are using these formulas.

Inelastic neutron scattering studies on the 3d-4f heterometallic single-molecule magnet Mn2Nd2  

International Nuclear Information System (INIS)

The discovery of slow relaxation and quantum tunneling of the magnetization in Mn12ac more than 15 years ago has inspired both physicists and chemists alike. This class of molecules, now called single-molecule magnets (SMMs), has very recently been expanded to heterometallic clusters incorporating transition metal and rare earth ions. The 4f ions were chosen because of their large angular momentum and magnetic anisotropy. Inelastic neutron scattering experiments were performed on the time-of-flight disk-chopper spectrometer IN5 at ILL on the SMM Mn2Nd2. A magnetic model was developed which perfectly describes all data, including the magnetic data. It was found that neither the large anisotropy nor the large angular momentum of the NdIII ions is the main reason for the SMM behavior in this molecule. Our analysis of the data indicates that it is the weak coupling of the NdIII ions to the MnIII ions, usually considered as a drawback of rare earth ions, which enhances the relaxation time and therefore leads to SMM behavior.

Effect of Software Manager, Programmer and Customer over Software Quality  

Directory of Open Access Journals (Sweden)

Full Text Available Several factors might be affecting the quality of software products. In this study we focus on three significant parameters: software manager, programmer and the customer. Our study demonstrates that the quality of product will improve by increasing the information generated by these three parameters. These parameters can be considered as triangular which the quality is its centroid. In this perspective, if the triangular be equilateral, then the optimum quality of the product will beachieved. In other words, to generate high quality software, the ability of software manager, programmer and customer must be same. Subsequently, only a manager or only an expert programmer, and with a software aware customer cannot be a guarantee to the high quality of the software products.

What difference does a year of schooling make? Maturation of brain response and connectivity between 2nd and 3rd grades during arithmetic problem solving.  

Science.gov (United States)

Early elementary schooling in 2nd and 3rd grades (ages 7-9) is an important period for the acquisition and mastery of basic mathematical skills. Yet, we know very little about neurodevelopmental changes that might occur over a year of schooling. Here we examine behavioral and neurodevelopmental changes underlying arithmetic problem solving in a well-matched group of 2nd (n = 45) and 3rd (n = 45) grade children. Although 2nd and 3rd graders did not differ on IQ or grade- and age-normed measures of math, reading and working memory, 3rd graders had higher raw math scores (effect sizes = 1.46-1.49) and were more accurate than 2nd graders in an fMRI task involving verification of simple and complex two-operand addition problems (effect size = 0.43). In both 2nd and 3rd graders, arithmetic complexity was associated with increased responses in right inferior frontal sulcus and anterior insula, regions implicated in domain-general cognitive control, and in left intraparietal sulcus (IPS) and superior parietal lobule (SPL) regions important for numerical and arithmetic processing. Compared to 2nd graders, 3rd graders showed greater activity in dorsal stream parietal areas right SPL, IPS and angular gyrus (AG) as well as ventral visual stream areas bilateral lingual gyrus (LG), right lateral occipital cortex (LOC) and right parahippocampal gyrus (PHG). Significant differences were also observed in the prefrontal cortex (PFC), with 3rd graders showing greater activation in left dorsal lateral PFC (dlPFC) and greater deactivation in the ventral medial PFC (vmPFC). Third graders also showed greater functional connectivity between the left dlPFC and multiple posterior brain areas, with larger differences in dorsal stream parietal areas SPL and AG, compared to ventral stream visual areas LG, LOC and PHG. No such between-grade differences were observed in functional connectivity between the vmPFC and posterior brain regions. These results suggest that even the narrow one-year interval spanning grades 2 and 3 is characterized by significant arithmetic task-related changes in brain response and connectivity, and argue that pooling data across wide age ranges and grades can miss important neurodevelopmental changes. Our findings have important implications for understanding brain mechanisms mediating early maturation of mathematical skills and, more generally, for educational neuroscience. PMID:21620984

Heart Hopscotch: Teaching Cardiovascular Physiology to 2nd Graders - PhUn Week Poster Session EB 2012  

Science.gov (United States)

Arizona currently ranks in the bottom 10th for education in the United States. In an effort to encourage science education, we designed PhUn Week activities for 2nd grade students at Kyrene de los Niños elementary school in Tempe, AZ. The emphasis of the activities was basic anatomy of the heart and the flow of blood through the heart. Methods: Students were first asked to draw a scientist according to their perceptions of what a scientist looks like. They were then asked to draw what they thought the heart looked like as well as guess the sizes of hearts for various animals. Through these activities and some basic questions, the educators were able to assess the baseline knowledge of the students. Using heart models, we were able to teach the students about the anatomy of their hearts. During the final activity that we designed, ÃÂHopscotch through the HeartÃÂ, students were able to hop or walk through a diagram of the heart drawn in chalk on the sidewalk. Each student pretended to be a blood cell being pumped by the heart, and described their path as they made their way through the heart and into the lungs to collect oxygen then back through the heart where they were then pumped out to the body. Results: Studentsàunderstanding of cardiovascular physiology seemed to improve based upon verbal and physical demonstration of their knowledge with the Hopscotch activity. More importantly, they seemed to have a lot of fun while learning. Students asked about the size of their own hearts and the size of other animalsàin comparison. Conclusion: Involving different modes of learning àlecture/discussion, visual (drawing), and kinesthetic (Hopscotch) àappears to be effective at educating elementary students about cardiovascular physiology.

ENABLE -- A systolic 2nd level trigger processor for track finding and e/? discrimination for ATLAS/LHC  

International Nuclear Information System (INIS)

The Enable Machine is a systolic 2nd level trigger processor for the transition radiation detector (TRD) of ATLAS/LHC. It is developed within the EAST/RD-11 collaboration at CERN. The task of the processor is to find electron tracks and to reject pion tracks according to the EAST benchmark algorithm in less than 10?s. Track are identified by template matching in a (?,z) region of interest (RoI) selected by a 1st level trigger. In the (?,z) plane tracks of constant curvature are straight lines. The relevant lines form mask templates. Track identification is done by histogramming the coincidences of the templates and the RoI data for each possible track. The Enable Machine is an array processor that handles tracks of the same slope in parallel, and tracks of different slope in a pipeline. It is composed of two units, the Enable histogrammer unit and the Enable z/?-board. The interface daughter board is equipped with a HIPPI-interface developed at JINR/-Dubna, and Xilinx 'corner turning' data converter chips. Enable uses programmable gate arrays (XILINX) for histogramming and synchronous SRAMs for pattern storage. With a clock rate of 40 MHz the trigger decision time is 6.5 ?s and the latency 7.0 ?s. The Enable machine is scalable in the RoI size as well as in the number of tracks processed. It can be adapted to different recognition tasks and detector setups. The prototype of the Enable Machine has been tested in a beam time of the RD6 collaboration at CERN in October 1993

Two U-7wt.%Mo dispersion fuel rods with different fuel particle sizes, two U- 7wt.%Mo dispersion fuel rods surface-treated with pre-oxidation and Ni coating, one U-7wt.%Mo dispersion fuel rod with a poison material of Er2O3, a U-9wt.%Mo dispersion fuel rod, and a U3Si dispersion fuel rod were loaded in the KOMO-test (the 2nd irradiation test of U-Mo fuels in HANARO by KAERI). In addition, the monolithic U-Mo ring fuel was loaded to develop higher U-density fuel. The fuel assembly with the above 10 fuel rods was irradiated in HAHARO successfully from January 9, 2003 to January 27, 2004. After cooling them for about 3 months, the PIE has been performed. Most of the fuel particles were interacted with the Al matrix in the central area of the rod-type U-Mo dispersion fuels with a high linear power and a higher burnup than 60 at.%. Some large pores were observed between the particles in the central area of the fuel rods. However the swellings of the fuel meats are not large, at less than 17 %. The fuel of a larger particle-size distribution showed a better stability than the fuel of a smaller particle-size distribution. Any surface treatments were observed to have no improvement on the oxidation layer formation of the cladding surface. U3Si dispersion fuel used as a reference showed a much lesser interaction with the matrix Al when compared with the U-Mo dispersion fuel. In an examination for the tubular monolithic U-Mo fuel abnormal phenomena such as many bubbles and a large swelling happened due to an unexpected contamination of the silicon from the quartz tube used for a mold during melting and casting process.

A verification of the high density after contrast enhancement in the 2nd week in cerebroischemic lesion  

International Nuclear Information System (INIS)

To determine the indication, it is necessary to make clear the relation among the Stage (time and course), the Strength, the Pathogenesis, and the Effects of the operation in these diseases (SSPE relation). In this report, we focused on the High Density of CT after the contrast enhancement in the cases of ischemic lesions (the High Density was named ''Ribbon H. D.''). Seventeen cases of Ribbon H. D. in fresh infarctions were verified concerning the time of the appearance of the H. D., the features of its location and nature, and the histological findings. The results were as follows: The Ribbon H. D. appeared in the early stage of infarctions, and had its peak density at the end of the 2nd week after the onset. The Ribbon H. D. was mostly located along the cortical line, showing a ribbon-like band. The Ribbon H. D. did not appear in the sharply demarcated coagulation necrosis in the early stage or in the defined Low Density (L. D.) in the late stage of infarctions. Although the Ribbon H. D. shows the extravasation of contrast media, it does not necessarily show the existence of the hemorrhagic infarction. Some part of the Ribbon H. D. changes to a well-defined L. D. and the rest of the part becomes relative isodensity in the late stage. This change corresponds to the change in the incomplete necrosis which is afterwards divided into a resolution with a cystic cavity and the glial replacement in the late stage. In conclusion, it is possible to understand that the Ribbon H. D. corresponds to the lesion of an incomplete necrosis, with neovascularization, in the early stage of infarctions. Therefore, in addition to the present indication of a by-pass operation (TIA, RIND), this incomplete necrosis (Ribbon H. D.), its surrounding area and just before the appearance of the Ribbon H. D. might be another indication of the operation. (author)

Accumulation of structural defects in ion-irradiated Ca2Nd8(SiO4)6O2  

International Nuclear Information System (INIS)

Ion irradiations of the rare-earth orthosilicate, Ca2Nd8(SiO4)6O2, have been carried out using both alpha particles (emitted from a 238PuO2 source) and 3 MeV argon ions. The unit cell exhibits anisotropic expansion under irradiation, consistent with expectations based on the polyhedral connectivity within the structure. A least-squares analysis of the interatomic distances suggests that the unit-cell expansions are primarily due to changes in oxygen-oxygen distances and cation separations between neighboring polyhedra rather than to bonds within polyhedra. The irradiation-induced change in unit-cell volume is proportional to 1-exp(-BD), where B is an annealing rate constant and D is the dose, in agreement with a model for the accumulation of isolated point defects in the structure. The volume expansion saturates at 2.56% and 1.40% for the alpha and argon irradiations, respectively. Analysis of the results suggests that a significant fraction of the defects produced in the argon-ion displacement cascades are lost to in-cascade recombination. Differential scanning calorimetry of powder irradiated with 3 MeV argon ions to 20 ions/nm2 reveals an exothermic recovery peak at 350 degree C with an activation energy of 1.3±0.1 eV and average stored energy release of 28.2 J/g. There is no evidence for amorphization of this material under alpha or argon irradiation

Software management issues  

Energy Technology Data Exchange (ETDEWEB)

The difficulty of managing the software in large HEP collaborations appears to becoming progressively worst with each new generation of detector. If one were to extrapolate to the SSC, it will become a major problem. This paper explores the possible causes of the difficulty and makes suggestions on what corrective actions should be taken.

Application of Software Safety Analysis Methods  

Energy Technology Data Exchange (ETDEWEB)

A fully digitalized reactor protection system, which is called the IDiPS-RPS, was developed through the KNICS project. The IDiPS-RPS has four redundant and separated channels. Each channel is mainly composed of a group of bistable processors which redundantly compare process variables with their corresponding setpoints and a group of coincidence processors that generate a final trip signal when a trip condition is satisfied. Each channel also contains a test processor called the ATIP and a display and command processor called the COM. All the functions were implemented in software. During the development of the safety software, various software safety analysis methods were applied, in parallel to the verification and validation (V and V) activities, along the software development life cycle. The software safety analysis methods employed were the software hazard and operability (Software HAZOP) study, the software fault tree analysis (Software FTA), and the software failure modes and effects analysis (Software FMEA)

Turbulence statistics of Couette Poiseuille turbulent flow. 2nd Report. Higher order turbulence statistics; Couette Poiseuille gata ranryu no midare tokeiryo. 2. Koji tokeiryo  

Energy Technology Data Exchange (ETDEWEB)

Turbulence statistics in Couette Poiseuille flow are obtained by measurements. These include correlation coefficient, skewness and flatness factors and four-quadrant analysis of Reynolds shear stress -{rho}uv. In the region of y{sup +} {<=}30-40, the distributions of all these quantities are only affected by non-dimensional parameter {mu}({identical_to}u*{sup 3}/{alpha}{nu}), as the mean velocity and the turbulence intensities profiles are. The four-quadrant analysis shows that the fractional contribution from 4th-quadrant is affected largely by parameter {mu} whereas that from 2nd-quadrant remains unaffected. In the case of 0<{mu}{<=}94, the fractional contribution from 4th-quadrant is greater than that from 2nd-quadrant, unlike the conventional wall turbulent flow. 8 refs., 17 figs., 2 tabs.

Generations.  

Science.gov (United States)

Groups naturally promote their strengths and prefer values and rules that give them an identity and an advantage. This shows up as generational tensions across cohorts who share common experiences, including common elders. Dramatic cultural events in America since 1925 can help create an understanding of the differing value structures of the Silents, the Boomers, Gen Xers, and the Millennials. Differences in how these generations see motivation and values, fundamental reality, relations with others, and work are presented, as are some applications of these differences to the dental profession.

Software engineering  

Science.gov (United States)

Today's software systems generally use obsolete technology, are not integrated properly with other software systems, and are difficult and costly to maintain. The discipline of reverse engineering is becoming prominent as organizations try to move their systems up to more modern and maintainable technology in a cost effective manner. The Johnson Space Center (JSC) created a significant set of tools to develop and maintain FORTRAN and C code during development of the space shuttle. This tool set forms the basis for an integrated environment to reengineer existing code into modern software engineering structures which are then easier and less costly to maintain and which allow a fairly straightforward translation into other target languages. The environment will support these structures and practices even in areas where the language definition and compilers do not enforce good software engineering. The knowledge and data captured using the reverse engineering tools is passed to standard forward engineering tools to redesign or perform major upgrades to software systems in a much more cost effective manner than using older technologies. The latest release of the environment was in Feb. 1992.

The 2006 Helsingborg Consensus Conference on European Stroke Strategies: Summary of conference proceedings and background to the 2nd Helsingborg Declaration.  

Science.gov (United States)

The 2nd Helsingborg Consensus Conference on European Stroke Strategies, was held March 2006 with the aims to update core issues in stroke management, to monitor progress, and to set new targets for the year 2015. the congress was organized by the International Society of Internal Medicine, endorsed by the European Stroke Council and the International Stroke Society, and co-sponsored by the WHO Regional Office for European. The meeting prepared the 2nd Helsingborg Declaration which details principles of care, research and development areas, and targets for the year 2015 in 5 areas of stroke management: organization of stroke services, management of acute stroke, prevention, rehabilitation, and evaluation of stroke outcome and quality assessment. The burden of stroke in European will increase markedly in the next decades. There is substantial evidence on insufficient control of major risk factors for stroke, in particular hypertension. The organization of stroke services plays a key role in the provision of effective therapies, but stroke units and facilities for provision of thrombolytic therapy remain suboptimal. Cognitive long term effects of stroke, and caregiver strain, have been underrecognized areas. Quality assessment as an integral part of services is still not established in most geographical areas. Several of the original Helsingborg Declaration goals for 2005 were found not to have been met. Some goals for 2015 in the 2nd Helsingborg Declaration was therefore kept unchanged or only slightly modified. The present report summarizes the proceedings held during the conference and provides further perspectives on the 2006 Helsingborg Declaration. PMID:18705975

Preparation of nanometric CeO{sub 2}-ZrO{sub 2}-Nd{sub 2}O{sub 3} solid solution and its catalytic performances  

Energy Technology Data Exchange (ETDEWEB)

A kind of nanometric CeO{sub 2}-ZrO{sub 2}-Nd{sub 2}O{sub 3} (CZN) solid solution for a carrier in the automotive three-way catalysts was synthesized by a coprecipitation method and characterized by means of X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), nitrogen adsorption-desorption (BET), scanning electron microscopy (SEM) and oxygen storage capacity (OSC). For the purpose of comparison, an unincorporated CeO{sub 2}-ZrO{sub 2} (CZ) was also synthesized. The XRD measurements disclose the prepared CeO{sub 2}-ZrO{sub 2}-Nd{sub 2}O{sub 3} have a face-centered cubic fluorite structure and nanoparticle sizes. According to the results of XPS, Nd{sup 3+} ions can enter the CZ lattice and form a homogenous solid solution. Oxygen storage capacity measurements reveal that CeO{sub 2}-ZrO{sub 2}-Nd{sub 2}O{sub 3} display high oxygen mobility at a low temperature. The results of the activity tests show that the catalyst exhibits good three-way catalytic activity and fairly wide range of air-to-fuel ratios.

The paper briefly reviews some of the fundamental difficulties presented by the design and the validation of software for safety critical applications. It suggests that software formal documentation techniques may be one way to ameliorate the problems described. The principles behind a method of documenting both requirements and software design are presented. The method has been followed by the Atomic Energy Control Board of Canada in its safety assessment of the software for the shutdown system of the Darlington nuclear power generating station. The method is illustrated by applying it to a small portion of the safety feature actuation system of a PWR reactor. (Author) 15 refs., 4 tabs., fig

Parametric Estimation of Software Systems  

Directory of Open Access Journals (Sweden)

Full Text Available Software is characterised by software metrics. Calculation of effort estimation is a type of software metrics. Software effort estimation plays a vital role in the development of software. In recent years, software has become the most expensive component of computer system projects. The major part of cost of software development is due to the human-effort, and most cost estimation methods focus on this aspect and give estimates in terms of person-month. In this paper, estimation of effort required for the development of software project is calculated using genetic algorithm approach. Software systems are becoming complex and they desire for new, effective and optimized technique with limited resources. A solution to this problem lies in nature where complex species have evolved from simple organisms and constantly become able to adapt to changes in the environment. In case of species, it takes hundreds of generations and years which are not considerable in the field of software engineering. With the use of genetic algorithm, it can be done instantly by simulating the results on various tools of genetic algorithm.

Also the extensive knowledge and practical experience about digital long-term preservation technologies have been acquired. This wide spectrum of activities puts us in the position to discuss the often overlooked aspect of the digital preservation - preservation of software programs. There are many resources dedicated to digital preservation of digital data, documents and multimedia records,but not so many about how to preserve the functionalities and features of computer programs. Exactly these functionalities - dynamic response to inputs - render the computer programs rich compared to documents or linear multimedia. The article opens the questions on the beginning of the way to the permanent digital preservation. The purpose is to find a way in the right direction, where all relevant aspects will be covered in proper balance. The following questions are asked: why at all to preserve computer programs permanently, who should do this and for whom, when we should think about permanent program preservation, what should be persevered (such as source code, screenshots, documentation, and social context of the program - e.g. media response to it ..., where and how?

Full Text Available The reality is that the statistical methods used for analysis of data depend upon the availability ofsoftware. Analysis of marked animal data is no different than the rest of the statistical field. Themethods used for analysis are those that are available in reliable software packages. Thus, the criticalimportance of having reliable, up–to–date software available to biologists is obvious. Statisticians havecontinued to develop more robust models, ever expanding the suite of potential analysis methodsavailable. But without software to implement these newer methods, they will languish in the abstract,and not be applied to the problems deserving them.In the Computers and Software Session, two new software packages are described, a comparison ofimplementation of methods for the estimation of nest survival is provided, and a more speculative paperabout how the next generation of software might be structured is presented.Rotella et al.

Nests are assumed to be visited atvarious, possibly infrequent, intervals. All of the approaches described compute nest survival with thesame likelihood, and require that the age of the nest is known to account for nests that eventually hatch.However, each approach offers advantages and disadvantages, explored by Rotella et al. (2004.Efford et al. (2004 present a new software package called DENSITY. The package computes populationabundance and density from trapping arrays and other detection methods with a new and unique approach.DENSITY represents the first major addition to the analysis of trapping arrays in 20 years.Barker & White (2004 discuss how existing software such as Program MARK require that each newmodel’s likelihood must be programmed specifically for that model. They wishfully think that futuresoftware might allow the user to combine pieces of likelihood functions together to generate estimates.The idea is interesting, and maybe some bright young statistician can work out the specifics toimplement the procedure.Choquet et al. (2004 describe MSURGE, a software package that implements the multistate capture–recapture models. The unique feature of MSURGE is that the design matrix is constructed with an interpretedlanguage called GEMACO. Because MSURGE is limited to just multistate models, the special requirementsof these likelihoods can be provided.The software and methods presented in these papers gives biologists and wildlife managers anexpanding range of possibilities for data analysis. Although ease–of–use is generally getting better,it does not replace the need for understanding of the requirements and structure of the modelsbeing computed. The internet provides access to many free software packages as well as user–discussion groups to share knowledge and ideas.

Software development method for safety critical applications  

Energy Technology Data Exchange (ETDEWEB)

The introduction of computer-based automation systems to safety critical applications is largely hampered by the fact that there is no generally accepted method for quantifying the reliability of software. The introductory chapter discusses the reliability of technical equipment in general and of the software in particular. Expanding on this, a software development procedure is then described that permits the generation of highly reliable software. (orig.) (5 refs., 3 figs.).

Global Software Engineering: A Software Process Approach  

Science.gov (United States)

Our research has shown that many companies are struggling with the successful implementation of global software engineering, due to temporal, cultural and geographical distance, which causes a range of factors to come into play. For example, cultural, project managementproject management and communication difficulties continually cause problems for software engineers and project managers. While the implementation of efficient software processes can be used to improve the quality of the software product, published software process models do not cater explicitly for the recent growth in global software engineering. Our thesis is that global software engineering factors should be included in software process models to ensure their continued usefulness in global organisations. Based on extensive global software engineering research, we have developed a software process, Global Teaming, which includes specific practices and sub-practices. The purpose is to ensure that requirements for successful global software engineering are stipulated so that organisations can ensure successful implementation of global software engineering.

GREEN SOFTWARE ENGINEERING PROCESS : MOVING TOWARDS SUSTAINABLE SOFTWARE PRODUCT DESIGN  

Directory of Open Access Journals (Sweden)

Full Text Available The Software development lifecycle (SDLC currently focuses on systematic execution and maintenance of software by dividing the software development process into various phases that include requirements-gathering, design, implementation, testing, deployment and maintenance. The problem here is that certain important decisions taken in these phases like use of paper, generation of e-Waste, power consumption and increased carbon foot print by means of travel, Air-conditioning etc may harm the environment directly or indirectly. There is a dearth of models that define how a software can be developed and maintained in an environment friendly way. This paper discusses the changes in the existing SDLC and suggests appropriate steps which can lead to lower carbon emissions, power and paper use, thus helping organizations to move towards greener and sustainable software development.

On factors contributing to quality of nuclear control computer software  

International Nuclear Information System (INIS)

Safety related computer software has increasingly come into focus in the software engineering field over the past decade. This paper describes how Ontario Hydro has addressed the software industry concerns in the methodology used for designing and implementing the unit control computer software for the new Darlington Generating Station. The corner stone of the methodology is a software quality assurance (SQA) program, which was initially set up to cover only the software development portion of the software life cycle, but which is now being extended to cover the entire software life cycle, including commissioning, operation and maintenance of the software.

Adaptation of Black-Box Software Components  

Directory of Open Access Journals (Sweden)

Full Text Available The globalization of the software market leads to crucial problems for software companies. More competition between software companies arises and leads to the force on companies to develop ever newer software products in ever shortened time interval. Therefore the time to market for software systems is shortened and obviously the product life cycle is shortened too. Thus software companies shortened the time interval for research and development. Due to the fact of competition between software companies software products have to develop low-priced and this leads to a smaller return on investment. A big challenge for software companies is the use of an effective research and development process to have these problems under control. A way to control these problems can be the reuse of existing software components and adapt those software components to new functionality or accommodate mismatched interfaces. Complete redevelopment of software products is more expensive and time consuming than to develop software components. The approach introduced here presents novel technique together with a supportive environment that enables developers to cope with the adaptability of black-box software components. A supportive environment will be designed that checks the compatibility of black-box software components with the assistance of their specifications. Generated adapter software components can take over the part of adaptation and advance the functionality. Besides, a pool of software components can be used to compose an application to satisfy customer needs. Certainly this pool of software components consists of black-box software components and adapter software components which can be connected on demand.

A Study of Mining Software Engineering Data and Software Testing  

Directory of Open Access Journals (Sweden)

Full Text Available The primary goal of software development is to deliver Optimal Software, i.e., software produced at low cost, high quality & productivity and scheduled with in time. In order to achieve this optimal software, programmers generally reuse the existing libraries, rather than developing similar code products right from the scratch. While reusing the libraries, programmers are facing several changes such as many existing libraries are not properly documented and many libraries contain large number of program interfaces (PIs through which libraries expose their functionality. These challenges lead to certain problems that affect in producing optimal software. The problems such as reuse of existing libraries consumes more time, lack of knowledge on reusage of program interfaces and we can’t generate effective test inputs during white box testing. The first two problems reduce the software productivity where as last one affect on software testing. To resolve these problems, we propose a general framework called Netminer. Netminer contains a code search engine. With the help of code search engine, we can search the available open source code over the internet. In the analysis phase, Netminer automatically compares the specifications of program interfaces with relevant code examples that are available in the internet. In the next phase, Netminer applies data mining techniques on code examples that are collected and identify common patterns. The common patterns represent exact usage of program interfaces. We propose some more approaches based on Netminer. Some approaches help programmers in effectively reusing program interfaces provided by existing libraries. Some approaches identify defects under analysis from the mined specifications and some approaches help in generating test inputs by the use of static and dynamic test generation. Our research study shows that Netminer framework can be effectively used in software engineering for achieving optimal software.

Software for mass spectrometer control  

International Nuclear Information System (INIS)

The paper describes a software application for the MAT 250 mass spectrometer control, which was refurbished. The spectrometer was bring-up-to-date using a hardware structure on its support where the software application for mass spectrometer control was developed . The software application is composed of dedicated modules that perform given operations. The instructions that these modules have to perform are generated by a principal module. This module makes possible the change of information between the modules that compose the software application. The use of a modal structure is useful for adding new functions in the future. The developed application in our institute made possible the transformation of the mass spectrometer MAT 250 into a device endowed with other new generation tools. (authors)

Software testing in roughness calculation  

International Nuclear Information System (INIS)

A test method to determine the function quality provided by the software for roughness measurement is presented in this study. The function quality of the software requirements should be part of and assessed through the entire life cycle of the software package. The specific function, or output accuracy, is crucial for the analysis of the experimental data. For scientific applications, however, commercial software is usually embedded with specific instrument, which is used for measurement or analysis during the manufacture process. In general, the error ratio caused by the software would be more apparent especially when dealing with relatively small quantities, like the measurements in the nanometer-scale range. The model of 'using a data generator' proposed by NPL of UK was applied in this study. An example of the roughness software is tested and analyzed by the above mentioned process. After selecting the 'reference results', the 'reference data' was generated by a programmable 'data generator'. The filter function of 0.8 mm long cutoff value, defined in ISO 11562 was tested with 66 sinusoid data at different wavelengths. Test results from commercial software and CMS written program were compared to the theoretical data calculated from ISO standards. As for the filter function in this software, the result showed a significant disagreement between the reference and test results. The short cutoff feature for filtering at the high frequencies does not function properly, while the long cutoff feature has the maximum difference in the filtering ratio, which is more than 70% between the wavelength of 300 ?m and 500 ?m. Conclusively, the commercial software needs to be tested more extensively for specific application by appropriate design of reference dataset to ensure its function quality
