    Being able to act remotely in our homes could be very useful in providing various services such as surveillance and remote interventions, which are key features for telehomecare applications. In addition to navigation and environmental challenges that a telepresence robot would face in home settings, the system requires an appropriate teleoperation interface for safe and efficient usage by novice users. This paper describes the design criteria and characterizes visualization and control modalities of user interfaces with a real robot. By considering the user's needs along with the current state of the art in teleoperation interfaces, two novel mixed-reality visualization modalities are compared with standard video-centric and map-centric perspectives. We report teleoperation trials under six different task scenarios with a sample of 37 novice operators in homelike conditions. The results based on three quantitative metrics and one qualitative metric outline under which conditions the novel mixed-reality visualization modalities significantly improve the performance of novice users.

    Varghese, Nishad G.

    Knowledge management (KM) exists in various forms throughout organizations. Process documentation, training courses, and experience sharing are examples of KM activities performed daily. The goal of KM systems (KMS) is to provide a tool set which serves to standardize the creation, sharing, and acquisition of business critical information. Existing literature provides numerous examples of targeted evaluations of KMS, focusing on specific system attributes. This research serves to bridge the targeted evaluations with an industry-specific, holistic approach. The user preferences of aerospace employees in engineering and engineering-related fields were compared to profiles of existing aerospace KMS based on three attribute categories: technical features, system administration, and user experience. The results indicated there is a statistically significant difference between aerospace user preferences and existing profiles in the user experience attribute category, but no statistically significant difference in the technical features and system administration attribute categories. Additional analysis indicated in-house developed systems exhibit higher technical features and user experience ratings than commercial-off-the-self (COTS) systems.

    1995-12-01

    The Trajectory Analysis and Optimization System (TAOS) is software that simulates point--mass trajectories for multiple vehicles. It expands upon the capabilities of the Trajectory Simulation and Analysis program (TAP) developed previously at Sandia National Laboratories. TAOS is designed to be a comprehensive analysis tool capable of analyzing nearly any type of three degree-of-freedom, point-mass trajectory. Trajectories are broken into segments, and within each segment, guidance rules provided by the user control how the trajectory is computed. Parametric optimization provides a powerful method for satisfying mission-planning constraints. Althrough TAOS is not interactive, its input and output files have been designed for ease of use. When compared to TAP, the capability to analyze trajectories for more than one vehicle is the primary enhancement, although numerous other small improvements have been made. This report documents the methods used in TAOS as well as the input and output file formats.

    Full Text Available The Web has evolved from mere HTML static pages to dynamic pages and providing information to users in interactive and engaging ways. One of the most revolutionary tools that has changed the online experience of Internet users is the Macromedia Flash. Nowadays, Web designers are providing both the HTML and Flash interfaces to users. However, the users are still not sure about which interface style, i.e., hypertext-based HTML interface or animation-based Flash interface, is better to use in terms of usability and effectiveness. This paper compares the strengths and weaknesses of both animated and hypertext Web interfaces in terms of their usability and also users’ attitudes and perceptions about these interfaces. To conduct the comparative study, an animated user interface was developed using Flash for the Division of Information Studies websiteof Nanyang Technological University, Singapore. This interface was compared with the existing hypertext user interface of the same website. It was found that animated user interface was preferred for its text readability, appropriate use of colours and buttons, visual consistency and sequencing of screens, attractiveness of design, pleasantness and user-friendliness of interface, ease of use, content coverage, organisation of information, navigation, and usability. The hypertext user interface was preferred for its speed of downloading and its navigational capability that complemented the Web browser navigation.

    Larsen, E; Rise, J; Lund, K E

    2013-07-01

    The use of snus is increasing in Norway. In this study we examined differences between adolescents who were exclusive snus users, and adolescent non-users, smokers and dual users of snus and cigarettes on a number of psychosocial factors, categorized as risk variables and protective variables associated with involvement in health compromising behavior. We applied separate logistic regression models, where exclusive snus users (n=740) were compared with non-users (n=904), smokers (n=219), and dual users (n=367). Compared to non-users, the group of exclusive snus users was associated with variables traditionally predicting health risk behavior, such as smoking friends (OR=1.74, SD 1.27-2.38) and truancy (OR=2.12, SD 1.65-2.78). Compared to smokers, exclusive snus users were related to variables traditionally associated with protection against involvement in health risk behavior, e.g. higher academic orientation (OR=1.66, SD 1.12-2.45). Associations with protective factors were also observed when exclusive snus users were compared with dual users. While the group of exclusive snus users was associated with a pattern of psychosocial risk compared to non-users, they showed a more conventional pattern when compared to smokers and dual users. The group of exclusive snus users may be described on a continuum varying from psychosocial risk factors to protective factors of risk involvement depending on the group of comparison. PMID:23583834

  14. Familial analysis of MMN in cannabis users: A case study

    2013-10-01

    Full Text Available Aims: The Mismatch Negativity (MMN is a brain event-related potential marker of sensory memory and prediction error, and is thought to index N-methyl-D-aspartate receptor-mediated glutamate neurotransmission functionality. MMN is reduced in patients with schizophrenia and in their unaffected first degree relatives. MMN is also reduced in chronic cannabis users and in ex-cannabis users (33-month abstinent. Reduced MMN in ex-users suggests that cannabis-related deficits may persist after cessation of use, or alternatively this may reflect a pre-existing condition. One way of potentially elucidating this issue, is to conduct a familial analysis of the MMN in cannabis users and their non-user first degree relatives: attenuated MMN in relatives might indicate a familial vulnerability to cannabis use or to glutamatergic dysfunction. Method: One sibling pair (one cannabis user, one non-user sibling and three non-user, unrelated, matched controls completed a multi-feature MMN paradigm with duration (100ms, frequency (1200Hz and intensity (90dB deviants (deviants 6%; standards 82%, 50ms, 1000Hz, 80dB. Results: Visual inspection of MMN waveforms and patterns of means suggests that non-user siblings have MMN amplitudes intermediate to their user-siblings (whose MMN is most attenuated and controls. Examination of confidence intervals for controls (reflecting MMN amplitude variability across conditions indicated that the user-sibling had smaller MMN amplitudes for all deviant conditions, and the non-user sibling had reduced duration MMN amplitude, compared to controls. Conclusions: These preliminary data provide early evidence that MMN might reflect a pre-existing vulnerability that is antecedent to cannabis use, but exacerbated by subsequent cannabis use, and may inform current conceptualisations of cannabis as a component cause of schizophrenia. However future research should attempt to replicate these findings in a larger sample.

  15. Comparative risk analysis

    International Nuclear Information System (INIS)

    In this paper, the risks of various energy systems are discussed considering severe accidents analysis, particularly the probabilistic safety analysis, and probabilistic safety criteria, and the applications of these criteria and analysis. The comparative risk analysis has demonstrated that the largest source of risk in every society is from daily small accidents. Nevertheless, we have to be more concerned about severe accidents. The comparative risk analysis of five different energy systems (coal, oil, gas, LWR and STEC (Solar)) for the public has shown that the main sources of risks are coal and oil. The latest comparative risk study of various energy has been conducted in the USA and has revealed that the number of victims from coal is 42 as many than victims from nuclear. A study for severe accidents from hydro-dams in United States has estimated the probability of dam failures at 1 in 10,000 years and the number of victims between 11,000 and 260,000. The average occupational risk from coal is one fatal accident in 1,000 workers/year. The probabilistic safety analysis is a method that can be used to assess nuclear energy risks, and to analyze the severe accidents, and to model all possible accident sequences and consequences. The 'Fault tree' analysis is used to know the probability of failure of the different systems at each point of accident sequences and to calculate the probability of risks. After calculating the probability of failure, the criteria for judging the numerical results have to be developed, that is the quantitative and qualitative goals. To achieve these goals, several systems have been devised by various countries members of AIEA. The probabilistic safety ana-lysis method has been developed by establishing a computer program permit-ting to know different categories of safety related information. 19 tabs. (author)

    International Nuclear Information System (INIS)

    CMS has a distributed computing model, based on a hierarchy of tiered regional computing centres. However, the end physicist is not interested in the details of the computing model nor the complexity of the underlying infrastructure, but only to access and use efficiently and easily the remote services. The CMS Remote Analysis Builder (CRAB) is the official CMS tool that allows the access to the distributed data in a transparent way. We present the current development direction, which is focused on improving the interface presented to the user and adding intelligence to CRAB such that it can be used to automate more and more the work done on behalf of user. We also present the status of deployment of the CRAB system and the lessons learnt in deploying this tool to the CMS collaboration.

    2000-10-01

    Research on lifting activities has led to the design of several useful tools for evaluating tasks that involve lifting and material handling. The National Institute for Occupational Safety and Health (NIOSH) has developed a single task lifting equation. This formula has been frequently used as a guide in the field of ergonomics and material handling. While being much more complicated, the multi-task formula will provide a more realistic analysis for the evaluation of lifting and material handling jobs. A user friendly tool has been developed to assist professionals in the field of ergonomics in analyzing multitask types of material handling jobs. The program allows for up to 10 different tasks to be evaluated. The program requires a basic understanding of the NIOSH lifting guidelines and the six multipliers that are involved in the analysis of each single task. These multipliers are: Horizontal Distance Multiplier (HM), Vertical Distance Multiplier (VM), Vertical Displacement Multiplier (DM), Frequency of lifting Multiplier (FM), Coupling Multiplier (CM), and the Asymmetry Multiplier (AM). Once a given job is analyzed, a researched list of recommendations is provided to the user in an attempt to reduce the potential risk factors that are associated with each task.

    The CMS experiment at LHC has had a distributed computing model since early in the project plan. The geographically distributed computing system is based on a hierarchy of tiered regional computing centers; data reconstructed at Tier-0 are then distributed and archived at Tier-1 where re-reconstruction on data events is performed and computing resources for skimming and selection are provided. The Tier-2 centers are the primary location for analysis activities. The analysis will be thus performed in a distributed way using Grid infrastructure. The CMS computing model architecture has also the goal to enable thousands physicist collaboration worldwide spread (about 2600 from 180 scientific institutes) to access data. In order to require to the end user a very limited knowledge of underlying technical details, CMS has been developed a set of specific tools using the Grid services. This model is being tested in many Grid Service Challenges of increasing complexity, coordinated with the Worldwide LHC Computing Gr...

  20. Comparing the Iowa and Soochow gambling tasks in opiate users

    2012-03-01

    Full Text Available The Iowa Gambling Task (IGT is in many respects the gold-standard for demonstrating decision-making in drug using groups. However, it is not clear how basic task properties such as the frequency and magnitude of rewards and losses affect choice behaviour in drug users and even in healthy players. In this study, we used a variant of the IGT, the Soochow Gambling Task (SGT, to observe choice behaviour in opiate users and healthy decision makers in a task where reward frequency is not confounded with the long-term outcome of each alternative. In both opiate users (n=26 and healthy controls (n=27, we show that reward frequency strongly influences choice behaviour in the IGT and SGT. Neither group showed a consistent preference across tasks for alternatives with good long-term outcomes, but rather, subjects appeared to prefer alternatives that win most frequently. We interpret this as evidence to suggest that healthy players perform better than opiate users on the IGT because they are able to utilize gain-loss frequencies to guide their choice behaviour on the task. This challenges the previous notion that poorer performance on the IGT in drug users is due to an inability to be guided by future consequences.

    Full Text Available In the competitive wireless market, there are many drivers behind customer defection. Switching barriers, service performance, perceived value in carriers' offers, satisfaction and other constructs can play a pivotal role in customer switching processes among carriers. This study attempts to compare [...] the influence of these factors, taking into account cultural similarities and dissimilarities, between Brazilian and German mobile users. A survey was conducted on two samples, comprising 202 users in Brazil and 200 users in Germany, with culture being employed as a context variable to compare their behavior. Analysis by means of multi-group structural equation modeling suggests that, in both countries, customer satisfaction, service performance and perceived value have important roles in defining customer switching intentions, while switching barriers did not prove to have significant effects upon switching behavior. The results also suggest that the two cultures are sufficiently similar (considering the sample and the variables involved in the model) to not present differences in the studied consumer behavior, except for the effect of service performance upon satisfaction.

    2016-01-01

    A number of studies have investigated different ways of visualizing uncertainty. However, in the temporal dimension, it is still an open question how to best represent uncertainty, since the special characteristics of time require special visual encodings and may provoke different interpretations. Thus, we have conducted a comprehensive study comparing alternative visual encodings of intervals with uncertain start and end times: gradient plots, violin plots, accumulated probability plots, error bars, centered error bars, and ambiguation. Our results reveal significant differences in error rates and completion time for these different visualization types and different tasks. We recommend using ambiguation - using a lighter color value to represent uncertain regions - or error bars for judging durations and temporal bounds, and gradient plots - using fading color or transparency - for judging probability values.

    Full Text Available The use of Instant Messaging, or IM, has become widely adopted in private and corporate communication. They can provide instant, multi-directed and multi-types of communications which make the message spreading in IM different from those in WWW, Blog and email systems. Groups have great impacts on message spreading in IM. The research demonstrates the power law distribution of groups in MSN with parameter ? ranging from 0.76 to 1.22. Based on an online survey, IM user behavior is analyzed from the aspects of message sending/receiving and contacts maintaining. According to the results, degree distribution of users has a peak value and doesn't present power law character. This may indicate that social networks should be a prospective direction for the research on IM topology.

  11. CMS Configuration Editor: GUI based application for user analysis job

    International Nuclear Information System (INIS)

    We present the user interface and the software architecture of the Configuration Editor for the CMS experiment. The analysis workflow is organized in a modular way integrated within the CMS framework that organizes in a flexible way user analysis code. The Python scripting language is adopted to define the job configuration that drives the analysis workflow. It could be a challenging task for users, especially for newcomers, to develop analysis jobs managing the configuration of many required modules. For this reason a graphical tool has been conceived in order to edit and inspect configuration files. A set of common analysis tools defined in the CMS Physics Analysis Toolkit (PAT) can be steered and configured using the Config Editor. A user-defined analysis workflow can be produced starting from a standard configuration file, applying and configuring PAT tools according to the specific user requirements. CMS users can adopt this tool, the Config Editor, to create their analysis visualizing in real time which are the effects of their actions. They can visualize the structure of their configuration, look at the modules included in the workflow, inspect the dependences existing among the modules and check the data flow. They can visualize at which values parameters are set and change them according to what is required by their analysis task. The integration of common tools in the GUI needed to adopt an object-oriented structure in the Python definition of the PAT tools and the definition of a layer of abstraction from which all PAT tools inherit.

    We present the user interface and the software architecture of the Configuration Editor for the CMS experiment. The analysis workflow is organized in a modular way integrated within the CMS framework that organizes in a flexible way user analysis code. The Python scripting language is adopted to define the job configuration that drives the analysis workflow. It could be a challenging task for users, especially for newcomers, to develop analysis jobs managing the configuration of many required modules. For this reason a graphical tool has been conceived in order to edit and inspect configuration files. A set of common analysis tools defined in the CMS Physics Analysis Toolkit (PAT) can be steered and configured using the Config Editor. A user-defined analysis workflow can be produced starting from a standard configuration file, applying and configuring PAT tools according to the specific user requirements. CMS users can adopt this tool, the Config Editor, to create their analysis visualizing in real time which are the effects of their actions.

    2012-12-01

    This paper describes known uses of NASA's Land Atmosphere Near-real time Capability for EOS (LANCE) data and imagery and summarizes findings from informal interviews with LANCE users, undertaken to better understand their needs. LANCE, the NRT component of EOSDIS, provides products from MODIS, AIRS, OMI and MLS within 3 hours of satellite observation. LANCE has in excess of 50,000 unique anonymous users per month using data and imagery for wildfire management, air quality measurements, shipping, agricultural forecasting as well as monitoring volcanic plumes, dust storms, smoke plumes and floods etc. Users can be categorized as end users or as brokers who may repackage the imagery and pass it on to their own end users. Interactions with a sample of end users found the following: users like MODIS Rapid Response imagery but do not want to be confined to pre-defined subsets; they want a broader selection of imagery and those with higher bandwidth want the capability to pull in imagery in to their own web-mapping or GIS applications. Users with lower bandwidth want the capability to define their own areas-of-interest for simple download of an image file. Users also expressed a desire to see historic as well as near-real time data, so they can compare the current situation to the recent past. Users want download capabilities to enable information to be shared quickly and easily. These and other findings are being fed back to EOSDIS developers who are creating tools and services to better meet user needs. The findings from users have been valuable in ensuring that developers are on track. The most recent offerings, available http://earthdata.nasa.gov/lance, are Worldview - a web-based client which provides capability to interactively browse full-resolution, global, near real-time satellite imagery from 50+ data products from LANCE, and the Global Imagery Browse Services (GIBS) which enables both users and brokers to pull the latest imagery in to their own web mapping applications.

  15. User-definable bull's-eye database analysis

    International Nuclear Information System (INIS)

    We developed a type of bull's-eye analysis which facilitates user-defined processing, and then explored the effects of various types of processing on the comparisons of patient information with that of reference databases. Male and female bull's-eye database were generated from 32 normal patients using unweighted 2D prefiltering, ramp backprojection, unweighted 3D postfiltering, and peak value circumferential plotting (base method). The data from each patient were then reprocessed and compared to the databases by means of three different approaches: (1) using the base method, (2) using average as opposed to peak value profiles, and (3) using a resolution recovery prefilter instead of a smoothing prefilter. Significant differences in the number of apparently abnormal regions were found between the three methods. In other words, the type of SPET-processing affected the accuracy of comparisons between patient and database information. Because even sophisticated analysis can now be performed on personal computers, we conclude that, rather than a pre-processed data file, clinical ''normal reference'' information should consist of original SPET data from a series of documented normal patients. Each user could then generate reference bull's-eye database by applying his or her own clinical processing procedures to the data. (orig./MG)

  16. Reinforcing user data analysis with Ganga in the LHC era: scalability, monitoring and user-support

    International Nuclear Information System (INIS)

    Ganga is a grid job submission and management system widely used in the ATLAS and LHCb experiments and several other communities in the context of the EGEE project. The particle physics communities have entered the LHC operation era which brings new challenges for user data analysis: a strong growth in the number of users and jobs is already noticeable. Current work in the Ganga project is focusing on dealing with these challenges. In recent Ganga releases the support for the pilot job based grid systems Panda and Dirac of the ATLAS and LHCb experiment respectively have been strengthened. A more scalable job repository architecture, which allows efficient storage of many thousands of jobs in XML or several database formats, was recently introduced. A better integration with monitoring systems, including the Dashboard and job execution monitor systems is underway. These will provide comprehensive and easy job monitoring. A simple to use error reporting tool integrated at the Ganga command-line will help to improve user support and debugging user problems. Ganga is a mature, stable and widely-used tool with long-term support from the HEP community. We report on how it is being constantly improved following the user needs for faster and easier distributed data analysis on the grid.

    2012-10-01

    This document is a user manual for the Dairy Analytics and Nutrient Analysis (DANA) model. DANA provides an analysis of dairy anaerobic digestion technology and allows users to calculate biogas production, co-product valuation, capital costs, expenses, revenue and financial metrics, for user customizable scenarios, dairy and digester types. The model provides results for three anaerobic digester types; Covered Lagoons, Modified Plug Flow, and Complete Mix, and three main energy production technologies; electricity generation, renewable natural gas generation, and compressed natural gas generation. Additional options include different dairy types, bedding types, backend treatment type as well as numerous production, and economic parameters. DANA’s goal is to extend the National Market Value of Anaerobic Digester Products analysis (informa economics, 2012; Innovation Center, 2011) to include a greater and more flexible set of regional digester scenarios and to provide a modular framework for creation of a tool to support farmer and investor needs. Users can set up scenarios from combinations of existing parameters or add new parameters, run the model and view a variety of reports, charts and tables that are automatically produced and delivered over the web interface. DANA is based in the INL’s analysis architecture entitled Generalized Environment for Modeling Systems (GEMS) , which offers extensive collaboration, analysis, and integration opportunities and greatly speeds the ability construct highly scalable web delivered user-oriented decision tools. DANA’s approach uses server-based data processing and web-based user interfaces, rather a client-based spreadsheet approach. This offers a number of benefits over the client-based approach. Server processing and storage can scale up to handle a very large number of scenarios, so that analysis of county, even field level, across the whole U.S., can be performed. Server based databases allow dairy and digester parameters be held and managed in a single managed data repository, while allows users to customize standard values and perform individual analysis. Server-based calculations can be easily extended, versions and upgrades managed, and any changes are immediately available to all users. This user manual describes how to use and/or modify input database tables, run DANA, view and modify reports.

    Many kinds of human reliability analysis (HRA) methods have been developed. However, users are required to be skillful so as to use them, and also required complicated works such as drawing event tree (ET) and calculation of uncertainty bounds. Moreover, each method is not so complete that only one method of them is not enough to evaluate human reliability. Therefore, a personal computer (PC) based support system for HRA has been developed to execute HRA practically and efficiently. The system consists of two methods, namely, simple method and detailed one. The former uses ASEP that is a simplified THERP-technique, and combined method of OAT and HRA-ET/DeBDA is used for the latter. Users can select a suitable method for their purpose. Human error probability (HEP) data were collected and a database of them was built to use for the support system. This paper describes outline of the HRA methods, support functions and user`s guide of the system. (author).

    Kratom (Mitragyna speciosa) is a psychoactive plant that has been used since at least 1836 in folk medicine in Southeast Asian countries. More recently, kratom has become widely available in the West and is used for both recreational and medicinal purposes. There has, however, been little scientific research into the short- and long-term effects of kratom in humans, and much of the information available is anecdotal. To supplement the increasing scientific understanding of kratom's pharmacology and research into its effects in animals, we report the results of a qualitative analysis of first-hand descriptions of human kratom use that were submitted to, and published by, a psychoactive substance information website (Erowid.org). Themes that emerged from these experience reports indicate that kratom may be useful for analgesia, mood elevation, anxiety reduction, and may aid opioid withdrawal management. Negative response themes also emerged, indicating potential problems and unfavorable "side" effects, especially stomach upset and vomiting. Based on our analyses, we present preliminary hypotheses for future examination in controlled, quantitative studies of kratom. PMID:26595229

    In this paper we carry out a comparative analysis of the word network as the collaboration network based on the novel by M. Bulgakov 'Master and Margarita', the synonym network of the Russian language as well as the Russian movie actor network. We have constructed one-mode projections of these networks, defined degree distributions for them and have calculated main characteristics. In the paper a generation algorithm of collaboration networks has been offered which allows one to generate networks statistically equivalent to the studied ones. It lets us reveal a structural correlation between word network, synonym network and movie actor network. We show that the degree distributions of all analyzable networks are described by the distribution of q-type.

    Full Text Available There are many methods of decision making by an ensemble of classifiers. The most popular are methods that have their origin in voting method, where the decision of the common classifier is a combination of individual classifiers’ outputs. This work presents comparative analysis of some classifier fusion methods based on weighted voting of classifiers’ responses and combination of classifiers’ discriminant functions. We discus different methods of producing combined classifiers based on weights. We show that it is not possible to obtain classifier better than an abstract model of committee known as an Oracle if it is based only on weighted voting but models based on discriminant function or classifier using feature values and class numbers could outperform the Oracle as well. Delivered conclusions are confirmed by the results of computer experiments carried out on benchmark and computer generated data.

The ETA Tool is a software program that augments the analysis and reporting capabilities of a commercial-off-the-shelf (COTS) testability analysis software package called the Testability Engineering And Maintenance System (TEAMS) Designer. An initial diagnostic assessment is performed by the TEAMS Designer software using a qualitative, directed-graph model of the system being analyzed. The ETA Tool utilizes system design information captured within the diagnostic model and testability analysis output from the TEAMS Designer software to create a series of six reports for various system engineering needs. The ETA Tool allows the user to perform additional studies on the testability analysis results by determining the detection sensitivity to the loss of certain sensors or tests. The ETA Tool was developed to support design and development of the NASA Ares I Crew Launch Vehicle. The diagnostic analysis provided by the ETA Tool was proven to be valuable system engineering output that provided consistency in the verification of system engineering requirements. This software user manual provides a description of each output report generated by the ETA Tool. The manual also describes the example diagnostic model and supporting documentation - also provided with the ETA Tool software release package - that were used to generate the reports presented in the manual

    The following report gives the reader an overview of and instructions on the proper use of the National Renewable Energy Laboratory Force and Loads Analysis Program (FLAP, version 2.2). It is intended as a tool for prediction of rotor and blade loads and response for two- or three-bladed rigid hub wind turbines. The effects of turbulence are accounted for. The objectives of the report are to give an overview of the code and also show the methods of data input and correct code execution steps in order to model an example two-bladed rigid hub turbine. A large portion of the discussion (Sections 6.0, 7.0, and 8.0) is devoted to the subject of inputting and running the code for wind turbulence effects. The ability to include turbulent wind effects is perhaps the biggest change in the code since the release of FLAP version 2.01 in 1988. This report is intended to be a user`s guide. It does not contain a theoretical discussion on equations of motion, assumptions, underlying theory, etc. It is intended to be used in conjunction with Wright, Buhl, and Thresher (1988).

    The J-2X Engine (built by Pratt & Whitney Rocketdyne,) in the Upper Stage of the Ares I Crew Launch Vehicle, will only start within a certain range of temperature and pressure for Liquid Hydrogen and Liquid Oxygen propellants. The purpose of the Simulink Integrated Performance Analysis Model is to verify that in all reasonable conditions the temperature and pressure of the propellants are within the required J-2X engine start boxes. In order to run the simulation, test variables must be entered at all reasonable values of parameters such as heat leak and mass flow rate. To make this testing process as efficient as possible in order to save the maximum amount of time and money, and to show that the J-2X engine will start when it is required to do so, a graphical user interface (GUI) was created to allow the input of values to be used as parameters in the Simulink Model, without opening or altering the contents of the model. The GUI must allow for test data to come from Microsoft Excel files, allow those values to be edited before testing, place those values into the Simulink Model, and get the output from the Simulink Model. The GUI was built using MATLAB, and will run the Simulink simulation when the Simulate option is activated. After running the simulation, the GUI will construct a new Microsoft Excel file, as well as a MATLAB matrix file, using the output values for each test of the simulation so that they may graphed and compared to other values.

  6. Strategic Analysis of Trust Models for User-Centric Networks

    2013-03-01

    Full Text Available We present a strategic analysis of a trust model that has recently been proposed for promoting cooperative behaviour in user-centric networks. The mechanism for cooperation is based on a combination of reputation and virtual currency schemes in which service providers reward paying customers and punish non-paying ones by adjusting their reputation, and hence the price they pay for services. We model and analyse this system using PRISM-games, a tool that performs automated verification and strategy synthesis for stochastic multi-player games using the probabilistic alternating-time temporal logic with rewards (rPATL. We construct optimal strategies for both service users and providers, which expose potential risks of the cooperation mechanism and which we use to devise improvements that counteract these risks.

  7. Sociological analysis and comparative education

    Science.gov (United States)

    Woock, Roger R.

    1981-12-01

    It is argued that comparative education is essentially a derivative field of study, in that it borrows theories and methods from academic disciplines. After a brief humanistic phase, in which history and philosophy were central for comparative education, sociology became an important source. In the mid-50's and 60's, sociology in the United States was characterised by Structural Functionalism as a theory, and Social Survey as a dominant methodology. Both were incorporated into the development of comparative education. Increasingly in the 70's, and certainly today, the new developments in sociology are characterised by an attack on Positivism, which is seen as the philosophical position underlying both functionalism and survey methods. New or re-discovered theories with their attendant methodologies included Marxism, Phenomenological Sociology, Critical Theory, and Historical Social Science. The current relationship between comparative education and social science is one of uncertainty, but since social science is seen to be returning to its European roots, the hope is held out for the development of an integrated social theory and method which will provide a much stronger basis for developments in comparative education.

  18. Rent control: a comparative analysis

    Scientific Electronic Library Online (English)

    S, Maass.

    Full Text Available Recent case law shows that vulnerable, previously disadvantaged private sector tenants are currently facing eviction orders - and consequential homelessness - on the basis that their leases have expired. In terms of the case law it is evident that once their leases have expired, these households do [...] not have access to alternative accommodation. In terms of the Constitution, this group of marginalised tenants have a constitutional right of access to adequate housing and a right to occupy land with legally secure tenure. The purpose of this article is to critically analyse a number of legislative interventions, and specifically rent control, that were imposed in various jurisdictions in order to provide strengthened tenure protection for tenants. The rationale for this analysis is to determine whether the current South African landlord-tenant regime is able to provide adequate tenure protection for vulnerable tenants and therefore in the process of transforming in line with the Constitution. The legal construction of rent control was adopted in pre-1994 South Africa, England and New York City to provide substantive tenure protection for tenants during housing shortages. These statutory interventions in the different private rental markets were justified on the basis that there was a general need to protect tenants against exploitation by landlords. However, the justification for the persistent imposition of rent control in New York City is different since it protects a minority group of financially weak tenants against homelessness. The English landlord-tenant regime highlights the importance of a well-structured social sector that can provide secure, long-term housing options for low-income households who are struggling to access the private rental sector. Additionally, the English rental housing framework shows that if the social sector is functioning as a "safety net" for low-income households, the private sector would be able to uphold deregulation. In light of these comparisons and the fact that the South African social sector is not functioning optimally yet, the question is whether the South African private sector is able to provide the required level of tenure protection for struggling tenants. Recent case law shows that tenants are at liberty to lodge unfair practice complaints with the Rental Housing Tribunals on the basis that the landlords' ground for termination of the lease constitutes an unfair practice. The Court defined an unfair practice as a practice that unreasonably prejudices the tenants' rights or interests. This judicial development signifies some transformation in the private sector since it allows the Tribunals to scrutinise landlords' reasons for termination of tenancies in light of tenants' personal and socioeconomic circumstances. The Tribunals are therefore empowered to weigh the interests of both parties and decide whether to confirm termination of the lease or set aside such termination. In light of this recent development, the Tribunals can provide strengthened tenure protection for destitute tenants on a case by case basis, which incorporates a flexible context-sensitive approach to the provision of secure housing rights in the landlord-tenant framework. This methodology is similar to the German approach. Even though this judicial development is welcomed, it raises some concerns with regard to landlords' property rights and specifically landlords' constitutional property rights since Tribunals are now at liberty to set aside contractually agreed grounds for termination of leases without any statutory guidance. The legislation fails to provide any information regarding legitimate grounds for termination, which might have to be rectified in future. The grounds listed in the rent control legislation should serve as a starting point to determine which grounds for termination of a lease should generally be upheld. However, German landlord-tenant law shows that a statutory ground for termination of a lease should not be imposed in an absolutist fashion but rather place a

  20. Performance analysis of an opportunistic multi-user cognitive network with multiple primary users

    KAUST Repository

    Khan, Fahd Ahmed

    2014-03-01

    Consider a multi-user underlay cognitive network where multiple cognitive users concurrently share the spectrum with a primary network with multiple users. The channel between the secondary network is assumed to have independent but not identical Nakagami-m fading. The interference channel between the secondary users (SUs) and the primary users is assumed to have Rayleigh fading. A power allocation based on the instantaneous channel state information is derived when a peak interference power constraint is imposed on the secondary network in addition to the limited peak transmit power of each SU. The uplink scenario is considered where a single SU is selected for transmission. This opportunistic selection depends on the transmission channel power gain and the interference channel power gain as well as the power allocation policy adopted at the users. Exact closed form expressions for the moment-generating function, outage performance, symbol error rate performance, and the ergodic capacity are derived. Numerical results corroborate the derived analytical results. The performance is also studied in the asymptotic regimes, and the generalized diversity gain of this scheduling scheme is derived. It is shown that when the interference channel is deeply faded and the peak transmit power constraint is relaxed, the scheduling scheme achieves full diversity and that increasing the number of primary users does not impact the diversity order. © 2014 John Wiley & Sons, Ltd.

  1. Micromechanical combined stress analysis: MICSTRAN, a user manual

    Science.gov (United States)

    Naik, R. A.

    1992-01-01

    Composite materials are currently being used in aerospace and other applications. The ability to tailor the composite properties by the appropriate selection of its constituents, the fiber and matrix, is a major advantage of composite materials. The Micromechanical Combined Stress Analysis (MICSTRAN) code provides the materials engineer with a user-friendly personal computer (PC) based tool to calculate overall composite properties given the constituent fiber and matrix properties. To assess the ability of the composite to carry structural loads, the materials engineer also needs to calculate the internal stresses in the composite material. MICSTRAN is a simple tool to calculate such internal stresses with a composite ply under combined thermomechanical loading. It assumes that the fibers have a circular cross-section and are arranged either in a repeating square or diamond array pattern within a ply. It uses a classical elasticity solution technique that has been demonstrated to calculate accurate stress results. Input to the program consists of transversely isotropic fiber properties and isotropic matrix properties such as moduli, Poisson's ratios, coefficients of thermal expansion, and volume fraction. Output consists of overall thermoelastic constants and stresses. Stresses can be computed under the combined action of thermal, transverse, longitudinal, transverse shear, and longitudinal shear loadings. Stress output can be requested along the fiber-matrix interface, the model boundaries, circular arcs, or at user-specified points located anywhere in the model. The MICSTRAN program is Windows compatible and takes advantage of the Microsoft Windows graphical user interface which facilitates multitasking and extends memory access far beyond the limits imposed by the DOS operating system.

  3. User's guide for the REBUS-3 fuel cycle analysis capability

    International Nuclear Information System (INIS)

    REBUS-3 is a system of programs designed for the fuel-cycle analysis of fast reactors. This new capability is an extension and refinement of the REBUS-3 code system and complies with the standard code practices and interface dataset specifications of the Committee on Computer Code Coordination (CCCC). The new code is hence divorced from the earlier ARC System. In addition, the coding has been designed to enhance code exportability. Major new capabilities not available in the REBUS-2 code system include a search on burn cycle time to achieve a specified value for the multiplication constant at the end of the burn step; a general non-repetitive fuel-management capability including temporary out-of-core fuel storage, loading of fresh fuel, and subsequent retrieval and reloading of fuel; significantly expanded user input checking; expanded output edits; provision of prestored burnup chains to simplify user input; option of fixed-or free-field BCD input formats; and, choice of finite difference, nodal or spatial flux-synthesis neutronics in one-, two-, or three-dimensions

    A physicist analysing data from the LHC experiments will have to deal with data and computing resources that are distributed across multiple locations and have different access methods. Ganga helps by providing a uniform high-level interface to the different low-level solutions for the required tasks, ranging from the specification of input data to the retrieval and post-processing of the output. For LHCb and ATLAS the goal is to assist in running jobs based on the Gaudi/Athena C++ framework. Ganga is written in python and presents the user with a single GUI rather than a set of different applications. It uses pluggable modules to interact with external tools for operations such as querying metadata catalogues, job configuration and job submission. At start-up, the user is presented with a list of templates for common analysis tasks, and information about ongoing tasks is stored from one invocation to the next. Ganga can also be used through a command line interface. This closely mirrors the functionality of ...

    Full Text Available This article presents a study about the preference of use in virtual social networks, using Facebook as object of study, to identify the motivational factors for the usability of this technology platform. The social network Facebook has been chosen to present a technological scenario of high sociability and virtual interaction. The methodology used was the netnography, being made through the collection of discussions in North American sites of news and forums online, where there is a large critical user participation on the internet, about the gains and frustrations in this context. The content analysis was performed comparing the categories of users found in the literature about values that motivate consumer technology, describing the hedonic, social, utilitarian values and perceptions of risk in consumption when related to lack of privacy. The results show two main groups of users of this technology and 7 subgroups. Therefore, the contribution of the study is that the formation of these groups may reflect technological usability of user groups around the world. The study also brings to the discussion issues related to the behaviors of the users of virtual networks which can be useful for businesses and their relationships with consumers and also the development of new knowledge from such criticism and demands that digital consumers expose about the technologies.

  7. International Reactor Physics Handbook Database and Analysis Tool (IDAT) - IDAT user manual

    International Nuclear Information System (INIS)

    The IRPhEP Database and Analysis Tool (IDAT) was first released in 2013 and is included on the DVD. This database and corresponding user interface allows easy access to handbook information. Selected information from each configuration was entered into IDAT, such as the measurements performed, benchmark values, calculated values and materials specifications of the benchmark. In many cases this is supplemented with calculated data such as neutron balance data, spectra data, k-eff nuclear data sensitivities, and spatial reaction rate plots. IDAT accomplishes two main objectives: 1. Allow users to search the handbook for experimental configurations that satisfy their input criteria. 2. Allow users to trend results and identify suitable benchmarks experiments for their application. IDAT provides the user with access to several categories of calculated data, including: - 1-group neutron balance data for each configuration with individual isotope contributions in the reactor system. - Flux and other reaction rates spectra in a 299-group energy scheme. Plotting capabilities were implemented into IDAT allowing the user to compare the spectra of selected configurations in the original fine energy structure or on any user-defined broader energy structure. - Sensitivity coefficients (percent changes of k-effective due to elementary change of basic nuclear data) for the major nuclides and nuclear processes in a 238-group energy structure. IDAT is actively being developed. Those approved to access the online version of the handbook will also have access to an online version of IDAT. As May 2013 marks the first release, IDAT may contain data entry errors and omissions. The handbook remains the primary source of reactor physics benchmark data. A copy of IDAT user's manual is attached to this document. A copy of the IRPhE Handbook can be obtained on request at http://www.oecd-nea.org/science/wprs/irphe/irphe-handbook/form.html

    DEFF Research Database (Denmark)

    BrunsŘ, Karen; Verbeke, Wim

    2009-01-01

    Purpose - The purpose of this paper is to investigate motives and barriers for eating fish among light users and heavy users, to discuss consumer evaluation of fish quality, and to explore the existence of cross-cultural fish consumer  segments. Design/methodology/approach - Qualitative data were collected through six focus group discussions, three in Spain and three in Belgium. In each country, one group consisted of heavy users while two groups included light users. Findings - The same attitudinal motives and barriers for fish consumption can be found in both countries and across user groups, even though fish consumption levels differ considerably. The main motives for eating fish are health and taste, while the main barriers are price perception, smell when cooking fish, and that fish does not deliver the same level of satiety as compared to meat. Big differences are found between countries and user groups with respect to preparation skills and the use of quality cues. Heavy users are very skilled in evaluating fish quality, especially those in Spain, while light users, especially those in Belgium, make seemingly irrational assumptions when evaluating the quality of fish. Research limitations/implications - This study is based on qualitative focus group discussions in two European countries only. Originality/value - This study explores and compares motives, barriers and quality evaluation among heavy and light fish consumers in two European countries. The paper yields valuable insights for further quantitative research into explaining variations in fish consumption, as well as for fish quality evaluation and fish market segmentation studies.

    Knight, Norman F. Jr.; Reeder, James R. (Technical Monitor)

    2006-01-01

    An overview of different types of composite material system architectures and a brief review of progressive failure material modeling methods used for structural analysis including failure initiation and material degradation are presented. Different failure initiation criteria and material degradation models are described that define progressive failure formulations. These progressive failure formulations are implemented in a user-defined material model (or UMAT) for use with the ABAQUS/Standard1 nonlinear finite element analysis tool. The failure initiation criteria include the maximum stress criteria, maximum strain criteria, the Tsai-Wu failure polynomial, and the Hashin criteria. The material degradation model is based on the ply-discounting approach where the local material constitutive coefficients are degraded. Applications and extensions of the progressive failure analysis material model address two-dimensional plate and shell finite elements and three-dimensional solid finite elements. Implementation details and use of the UMAT subroutine are described in the present paper. Parametric studies for composite structures are discussed to illustrate the features of the progressive failure modeling methods that have been implemented.

    Full Text Available The research was conducted in order to make comparative analysis of virtual education applications. The research is conducted in survey model. The study group consists of total 300 institutes providing virtual education in the fall, spring and summer semesters of 2004; 246 in USA, 10 in Australia, 3 in South Africa, 10 in India, 21 in UK, 6 in Japan, 4 in Turkey. The information has been collected by online questionnaire sent to the target mass by e-mail. The questionnaire has been developed in two information categories as personal information and institutes and their virtual education applications. The English web design of the online questionnaire and the database has been prepared by Microsoft ASP codes which is the script language of Microsoft Front Page editor and has been tested on personal web site. The questionnaire has been pre applied in institutions providing virtual education in Australia. The English text of the questionnaire and web site design have been sent to educational technology and virtual education specialists in the countries of the study group. With the feedback received, the spelling mistakes have been corrected and concept and language validity have been completed. The application of the questionnaire has taken 40 weeks during March-November 2004. Only 135 institutes have replied. Two of the questionnaires have been discharged because they included mistaken coding, names of the institutions and countries. Valid 133 questionnaires cover approximately 44% of the study group. Questionnaires saved in the online database have been transferred to Microsoft Excel and then to SPSS by external database connection. In regards of the research objectives, the data collected has been analyzed on computer and by using SPSS statistics package program. In data analysis frequency (f, percentage (% and arithmetic mean ( have been used. In comparisons of country, institute, year, and other variables, che-square test, independent t-Test and one way variance analysis (F Test have been used. Kruskal-Wallis H test and Mann-Whitney U test have been used. Although virtual education applications differentiate in choices and applications in different countries, education levels and types, after completion of the data analysis it is seen that study group consists of people whom are graduate and undergraduate level, personal users having education expectations, between the ages of 18-45 and working full time. They mostly offer programs providing undergraduate and graduate education in social sciences, giving accredited document, certificate and title. It is seen that most of the instructors have taken a planned education and they are mostly working as full time instructors and they are taking technical support. Financial resources are obtained from fees taken from students and the resources are mostly used for personnel costs. In applications central administration and organization take place and it is seen that they interfere with universities, for physical facilities they use information process centers and virtual classrooms, and for infrastructure and support services they use information process services. It is seen that while in the teaching process they use both synchronous and asynchronous presentation technologies; in order to support course content they use e-mail, web, cd, and course book technologies to provide basic learning environment function; they prefer different environments to cover face to face education needs; they take self learning and collaboration as basis and they take projects and term paper evaluations serious; they mostly prefer multiple choice tests and they usually make virtual courses exams through the internet. Regarding the characteristics of their institutions’ applications, the study group have agreed on mostly to connection and being dependent on connection opportunities. A significant difference between their institutions’ characteristics and the model for developing computer labs, when they had started to provide virtual lessons and presentation technologies u

    The ability to accurately predict the thermomechanical deformation response of advanced composite materials continues to play an important role in the development of these strategic materials. Analytical models that predict the effective behavior of composites are used not only by engineers performing structural analysis of large-scale composite components but also by material scientists in developing new material systems. For an analytical model to fulfill these two distinct functions it must be based on a micromechanics approach which utilizes physically based deformation and life constitutive models and allows one to generate the average (macro) response of a composite material given the properties of the individual constituents and their geometric arrangement. Here the user guide for the recently developed, computationally efficient and comprehensive micromechanics analysis code, MAC, who's predictive capability rests entirely upon the fully analytical generalized method of cells, GMC, micromechanics model is described. MAC is a versatile form of research software that 'drives' the double or triple ply periodic micromechanics constitutive models based upon GMC. MAC enhances the basic capabilities of GMC by providing a modular framework wherein (1) various thermal, mechanical (stress or strain control), and thermomechanical load histories can be imposed; (2) different integration algorithms may be selected; (3) a variety of constituent constitutive models may be utilized and/or implemented; and (4) a variety of fiber architectures may be easily accessed through their corresponding representative volume elements.

  16. Matrix analysis of the insider threat (MAIT) user's manual

    International Nuclear Information System (INIS)

    MAIT is a sophisticated method for the analysis of safeguards or security systems that determines if single or multiple insiders can covertly sabotage a facility or system, or can covertly divert a resource that is present in the facility or system. The MAIT method provides a detailed, organized way to exhaustively examine the safeguards or security system against these covert threats. An evaluation of this broad scope is beyond the reasonable capability of an analyst working without computer assistance. The MAIT analysis is conducted by first manually collecting detailed facility design data and access and control information for each individual safeguard measure. With this information, the MAIT computer code synthesizes every possible situation and returns data to the analyst concerning those particular events that are not adequately protected. This report replaces the previous user's manual (SAI-78-960-LJ). It includes the details that an analyst needs to know to use the upgraded MAIT evaluation method. The major changes incorporated in the present version of the method include the evaluation of scenarios that span two conditions, the consolidation of theft and sabotage versions of the program and the incorporation and consideration of secondary targets in a path

    Full Text Available One of the important issues in data mining is the interestingness problem. Typically, in a data mining process, the number of patterns discovered can easily exceed the capabilities of a human user to identify interesting results. To address this problem, utility measures have been used to reduce the patterns prior to presenting them to the user. A frequent itemset only reflects the statistical correlation between items, and it does not reflect the semantic significance of the items. This proposed approach uses a utility based itemset mining approach to overcome this limitation. This proposed system first uses Dbscan clustering algorithm which identifies the behavior of the users page visits, order of occurrence of visits. After applying the clustering technique High Two phase utility mining algorithm is applied, aimed at finding itemsets that contribute high utility.Mining web access sequences can discover very useful knowledge from web logs with broad applications. Mining useful Web path traversal patterns is a very important research issue in Web technologies. Knowledge about the frequent Web path traversal patterns enables us to discover the most interesting Websites traversed by the users. However, considering only the binary (presence/absence occurrences of the Websites in the Web traversal paths, real world scenarios may not be reflected. Therefore, if we consider the time spent by each user as a utility value of a website, more interesting web traversal paths can be discovered using proposed two-phase algorithm. User page visits are sequential in nature. In this paper MSNBC web navigation dataset is used to compare the efficiency and performance in web usage mining is finding the groups which share common interests General Terms Web session mining, log analysis.

    2014-10-01

    Full Text Available With the wide application of Internet in almost all fields, it has become the most important way for information publication, providing a large number of channels for spreading public opinion. Public opinions, as the response of Internet users to the information such as social events and government policies, reflect the status of both society and economics, which is highly valuable for the decision-making and public relations of enterprises. At present, the analysis methods for Internet public opinion are mainly based on discriminative approaches, such as Support Vector Machine (SVM and neural network. However, when these approaches analyze the sentiment of Internet public opinion, they are failed to exploit information hidden in text, e.g. topic. Motivated by the above observation, this paper proposes a detection method for public sentiment based on Probabilistic Latent Semantic Analysis (PLSA model. PLSA inherits the advantages of LSA, exploiting the semantic topic hidden in data. The procedure of detecting the public sentiment using this algorithm is composed of three main steps: (1 Chinese word segmentation and word refinement, with which each document is represented by a bag of words; (2 modeling the probabilistic distribution of documents using PLSA; (3 using the Z-vector of PLSA as the features of documents and delivering it to SVM for sentiment detection. We collect a set of text data from Weibo, blog, BBS etc. to evaluate our proposed approach. The experimental results shows that the proposed method in this paper can detect the public sentiment with high accuracy, outperforming the state-of-the-art approaches, i.e., word histogram based approach. The results also suggest that, text semantic analysis using PLSA could significantly boost the sentiment detection

    Full Text Available In present days of growing information technology, many browsers available for surfing and web mining. A user has option to use any of them at a time to mine out the desired website. Every browser has pre-defined level of popularity and reputation in the market. This paper considers the setup of only two browsers in a computer system and a user prefers to any one, if fails, switches to the other one .The behavior of user is modeled through Markov chain procedure and transition probabilities are calculated. The quitting to browsing is treated as a parameter of variation over the popularity. Graphical study is performed to explain the inter relationship between user behavior parameters and browser market popularity parameters. If rate of a company is lowest in terms of browser failure and lowest in terms of quitting probability then company enjoys better popularity and larger user proportion

    Sheth, Kapil S.; Gutierrez-Nolasco, Sebastian

    2010-01-01

    This paper presents an analysis of factors that impact user flight schedules during air traffic congestion. In pre-departure flight planning, users file one route per flight, which often leads to increased delays, inefficient airspace utilization, and exclusion of user flight preferences. In this paper, first the idea of filing alternate routes and providing priorities on each of those routes is introduced. Then, the impact of varying planning interval and system imposed departure delay increment is discussed. The metrics of total delay and equity are used for analyzing the impact of these factors on increased traffic and on different users. The results are shown for four cases, with and without the optional routes and priority assignments. Results demonstrate that adding priorities to optional routes further improves system performance compared to filing one route per flight and using first-come first-served scheme. It was also observed that a two-hour planning interval with a five-minute system imposed departure delay increment results in highest delay reduction. The trend holds for a scenario with increased traffic.

    International Nuclear Information System (INIS)

    The IAEA has been supporting its Member States in the area of energy planning for sustainable development. Development and dissemination of appropriate methodologies and their computer codes are important parts of this support. This manual has been produced to facilitate the use of the MAED model: Model for Analysis of Energy Demand. The methodology of the MAED model was originally developed by. B. Chateau and B. Lapillonne of the Institute Economique et Juridique de l'Energie (IEJE) of the University of Grenoble, France, and was presented as the MEDEE model. Since then the MEDEE model has been developed and adopted to be appropriate for modelling of various energy demand system. The IAEA adopted MEDEE-2 model and incorporated important modifications to make it more suitable for application in the developing countries, and it was named as the MAED model. The first version of the MAED model was designed for the DOS based system, which was later on converted for the Windows system. This manual presents the latest version of the MAED model. The most prominent feature of this version is its flexibility for representing structure of energy consumption. The model now allows country-specific representations of energy consumption patterns using the MAED methodology. The user can now disaggregate energy consumption according to the needs and/or data availability in her/his country. As such, MAED has now become a powerful tool for modelling widely diverse energy consumption patterns. This manual presents the model in details and provides guidelines for its application

    Due to the rapid growth in wireless local area networks (WLANs), it has become important to characterize the fine-grained structure of user association patterns. In this paper, we focus on unraveling the structure in user's daily association patterns in WLANs in the long run. The daily access pattern is defined by the fraction of time it spends with a particular location. We answer three questions: 1) Do users demonstrate consistent behavior? Using our novel metrics and clustering, we conclude that many users (more than 50%) are multi-modal. 2) Is it possible to represent user association patterns using a compact representation? Using eigen-decomposition, we show that the intrinsic dimensionality of the constructed user association matrices is low and only the top five eigenvalues and their corresponding eigenvectors can be used to reconstruct those association matrices with an error of 5%, in terms of the L1 and L2 matrix norms. 3) How can we decide if two users have similar association patterns?

    Full Text Available Voting through Short Message Service (SMS technology is fast and reliable as the mobile technology in Malaysia is quite advanced. Most of the SMS voting mechanism is easily understood by the public. There is no need to explain the voting process in detail as almost 80% of the mobile users know how to use the SMS service. SMS voting is just another way of sending a vote to the recipient by using short code instead of using a normal mobile number. SMS voting provides a useful, secure and reliable process as mobile users are informed of the charges incurred and receive a return SMS to acknowledge that their SMS vote has been received. The objective of this study is to study the characteristics of SMS voting adopters in terms of demographic factors as well as to explore the mobile users’ perception towards SMS voting. A survey using questionnaires was conducted to gain information and opinions from a convenience sample of 300 Malaysian mobile users regarding their perceptions on using SMS to vote. The findings revealed that approximately two-thirds of the Malay respondents use SMS voting, most mobile users in the sample are single and female, and that mobile users like to send their votes using SMS. There is a significant difference between the usage of SMS voting among female respondents. Of the respondents 80 per cent perceive that the ease of use factor has greatly influenced mobile users in using SMS for voting purposes.

    Full Text Available Generally user page visits are sequential in nature. The large number of Web pages on many Web sites has raised navigational problems. Markov chains have been used to model user sequential navigational behavior on the World Wide Web (WWW.The enormous growth in the number of documents in the WWW increases the need for improved link navigation and path analysis models. Link prediction and path analysis are important problems with a wide range of applications ranging from personalization to websites. The complete size of the WWW coupled with the variation in users' navigation patterns makes this a very difficult sequence modeling problem. This paper generalizes the concept of grey relational analysis to develop a technique, called grey relational pattern analysis associated with Markov chains for sequential web data, for analyzing the similarity between given patterns. Based on this technique, a clustering algorithm” Grey Clustering algorithm for Sequential Data” is proposed to finding cluster of a given data set .The problem of determining the optimal number of clusters .

    Full Text Available Public libraries have an exciting opportunity to help to bring everyone intothis global conversation and to bridge what is often called ‘the digital divide’. They can achieve this by providing information technology for public access, by teaching basic computer skills and by participating in programmes to combat illiteracy. The public library is the local centre of information, making all kinds of knowledge and information readily available to its users. The services of the public library are provided on the basis of equality of access for all, regardless of age, race, sex, religion, nationality, language or social status. Specific services and materials must be provided for those users who cannot, for whatever reason, use the regular services and materials, for example linguistic minorities, people with disabilities or people in hospital or prison. However, to fulfill the principle of access for all, they must also continue to maintain services that provide information in different ways, for example, through print or the oral tradition. These are likely to remain of vital importance for the foreseeable future.

    Full Text Available With the continued growth and proliferation of Web services and Web based information systems, the volumes of user data have reached astronomical proportions. Analyzing such data using Web Usage Mining can help to determine the visiting interests or needs of the web user. As web log is incremental in nature, it becomes a crucial issue to predict exactly the ways how users browse websites. It is necessary for web miners to use predictive mining techniques to filter the unwanted categories for reducing the operational scope. Markov models& its variations have also been used to analyze web navigation behavior of users. A user's web link transition on a particular website can be modeled using first, second-order or higher-order Markov models and can be used to make predictions regarding future navigation and to personalize the web page for an individual user. All higher order Markov model holds the promise of achieving higher prediction accuracies, improved coverage than any single-order Markov model but holds high state space complexity. Hence a Hybrid Markov Model is required to improve the operation performance and prediction accuracy significantly. Markov model is assumed to be a probability model by which users’ browsing behaviors can be predicted at category level. Bayesian theorem can also be applied to present and infer users’ browsing behaviors at webpage level. In this research, Markov models and Bayesian theorem are combined and a two-level prediction model is designed. By the Markov Model, the system can effectively filter the possible category of the websites and Bayesian theorem will help to predict websites accuracy. The experiments will show that our provided model has noble hit ratio for prediction.

    The ability of modern HEP experiments to acquire and process unprecedented amounts of data and simulation have lead to an explosion in the volume of information that individual scientists deal with on a daily basis. Explosion has resulted in a need for individuals to generate and keep large personal analysis data sets which represent the skimmed portions of official data collections, pertaining to their specific analysis. While a significant reduction in size compared to the original data, these personal analysis and simulation sets can be many terabytes or 10s of TB in size and consist of 10s of thousands of files. When this personal data is aggregated across the many physicists in a single analysis group or experiment it can represent data volumes on par or exceeding the official production samples which require special data handling techniques to deal with effectively. In this paper we explore the changes to the Fermilab computing infrastructure and computing models which have been developed to allow experimenters to effectively manage their personal analysis data and other data that falls outside of the typically centrally managed production chains. In particular we describe the models and tools that are being used to provide the modern neutrino experiments like NOvA with storage resources that are sufficient to meet their analysis needs, without imposing specific quotas on users or groups of users. We discuss the storage mechanisms and the caching algorithms that are being used as well as the toolkits are have been developed to allow the users to easily operate with terascale+ datasets.

    Users with anomalous behaviors in online communication systems (e.g. email and social medial platforms) are potential threats to society. Automated anomaly detection based on advanced machine learning techniques has been developed to combat this issue; challenges remain, though, due to the difficulty of obtaining proper ground truth for model training and evaluation. Therefore, substantial human judgment on the automated analysis results is often required to better adjust the performance of anomaly detection. Unfortunately, techniques that allow users to understand the analysis results more efficiently, to make a confident judgment about anomalies, and to explore data in their context, are still lacking. In this paper, we propose a novel visual analysis system, TargetVue, which detects anomalous users via an unsupervised learning model and visualizes the behaviors of suspicious users in behavior-rich context through novel visualization designs and multiple coordinated contextual views. Particularly, TargetVue incorporates three new ego-centric glyphs to visually summarize a user's behaviors which effectively present the user's communication activities, features, and social interactions. An efficient layout method is proposed to place these glyphs on a triangle grid, which captures similarities among users and facilitates comparisons of behaviors of different users. We demonstrate the power of TargetVue through its application in a social bot detection challenge using Twitter data, a case study based on email records, and an interview with expert users. Our evaluation shows that TargetVue is beneficial to the detection of users with anomalous communication behaviors. PMID:26529707

  7. User-friendly software for SANS data reduction and analysis

    International Nuclear Information System (INIS)

    At the Geesthacht Neutron Facility (GeNF) a new software is being developed for the reduction of two-dimensional small-angle neutron scattering (SANS) data. The main motivation for this work was to created software for users of our SANS facilities that is easy to use. Another motivation was to provide users with software they can also use at their home institute. Therefore, the software is implemented on a personal computer running WINDOWS. The program reads raw data from an area detector in binary or ascii format and produces ascii files containing the scattering curve. The cross section can be averaged over the whole area of the detector or over users defined sectors only. Scripts can be created for processing large numbers of files. (author)

    Mycobacterium spp. are renowned for being the causative agent of diseases like leprosy, Buruli ulcer and tuberculosis in human beings. With more and more mycobacterial genomes being sequenced, any knowledge generated from comparative genomic analysis would provide better insights into the biology, evolution, phylogeny and pathogenicity of this genus, thus helping in better management of diseases caused by Mycobacterium spp.With this motivation, we constructed MycoCAP, a new comparative analysis platform dedicated to the important genus Mycobacterium. This platform currently provides information of 2108 genome sequences of at least 55 Mycobacterium spp. A number of intuitive web-based tools have been integrated in MycoCAP particularly for comparative analysis including the PGC tool for comparison between two genomes, PathoProT for comparing the virulence genes among the Mycobacterium strains and the SuperClassification tool for the phylogenic classification of the Mycobacterium strains and a specialized classification system for strains of Mycobacterium abscessus. We hope the broad range of functions and easy-to-use tools provided in MycoCAP makes it an invaluable analysis platform to speed up the research discovery on mycobacteria for researchers.

  11. Interactive user's application to Genie 2000 spectroscopy system for automation of hair neutron activation analysis

    International Nuclear Information System (INIS)

    Full text: In recent years lower plants such as mosses or lichens and for arid countries bark and leaves of tree have been used as biomonitors in environmental studies. Alongside with plants the trace elemental human hair composition also has been used as an indicator of pollution of natural and industrial environments. Because of convenience, easy access, nondestruction of sampling, and also preservation of information for a long time period, human hair even more often and widely used in various researches. In the Institute of Nuclear Physics of the Academy of Sciences of the Republic of Uzbekistan hair trace element analysis in environment monitoring and mapping and in health status studies have been used. Scientist of activation analysis laboratory always has a lot of routine work on biological objects analysis, so they regularly improved applied nuclear techniques. At present one of such good work-out technique is consider a hair multielement instrumental neutron activation analysis using single comparator standard method. Since in frames of the 'Enhanced nuclear techniques for materials identification' STCU project, the Radioanalytical Center (RAC) was created in October 2004, for analysis such objects as metals and alloys, minerals and ores, hydrogeological samples, technological products, soils, fertilizers, biological samples, foodstuff, water, sediments, construction materials, as well as materials of unknown composition the unique equipment of RAC have been used. For example, human hair analysis has performed on the base of HP Ge-detector with high resolution gamma-spectrometer of Canberra Industries, Inc. Genie-2000 Spectroscopy System of Canberra spectrometers, represents the true state of the art in spectroscopy software platforms. Genie 2000 is a comprehensive set of capabilities for acquiring and analyzing spectra from Multichannel Analyzers (MCA). Its functions include MCA control, spectral display and manipulation, basic spectrum analysis and reporting. Genie 2000 software is available in several variations and with several layered optional packages. Genie 2000 Basic Spectroscopy and Gamma Analysis Software, which available in RAC permitting us automatically obtain nuclide identification report with all needed parameters. Any applications of Genie 2000 software have not possibility to calculate analyzed elements concentration. For automation this step of INAA by using Canberra Genie 2000 Spectroscopy System we developed user's 'Human hair analysis Application' software for single comparator standard method of hair INAA. The work with the developed Application for GENIE-2000 begins with the menu, which contains four items. 1. Copying of the data. 2. Data input. 3. Viewing, editing and analyzing of the data. 4. EXIT. The item 'Copying of the data' makes copying the entered values of special user parameters from one data source into another. It is very user-friendly. It is enough to him once in one data source to enter values of necessary parameters (nuclides name, ?-lines value, factors of transformation for various times of an irradiation and cooling). Further, with the help of procedure 'Copying of the data' he can transfer them to any other data source. The item 'Data input' is carried out with the help of Graphical Batch Tools function GBTPARS and specially developed set of Form Design Specification (FDS) files for this function. This developed Application works in interactive environment as a dialogue system with user and allows calculating required nuclides concentration in analyzed samples, separately for long-lived, middle-lived and short-lived nuclides. Using the Nuclide Library Editor and comprehensive standard libraries of Genie package we created three custom libraries: Stdlib.HairL, Stdlib.HairM, Stdlib.HairS, accordingly for long-, middle- and short-lived nuclides. After processing of the next data source the Application returns the user to the menu. From here he can continue data processing, having chosen the following data source, or through menu item EXIT to leave from the application. Th

  18. Users' manual for fault tree analysis code: CUT-TD

    International Nuclear Information System (INIS)

    The CUT-TD code has been developed to find minimal cut sets for a given fault tree and to calculate the occurrence probability of its top event. This code uses an improved top-down algorithm which can enhance the efficiency in deriving minimal cut sets. The features in processing techniques incorporated into CUT-TD are as follows: (1) Consecutive OR gates or consecutive AND gates can be coalesced into a single gate. As a result, this processing directly produces cut sets for the redefined single gate with each gate not being developed. (2) The independent subtrees are automatically identified and their respective cut sets are separately found to enhance the efficiency in processing. (3) The minimal cut sets can be obtained for the top event of a fault tree by combining their respective minimal cut sets for several gates of the fault tree. (4) The user can reduce the computing time for finding minimal cut sets and control the size and significance of cut sets by inputting a minimum probability cut off and/or a maximum order cut off. (5) The user can select events that need not to be further developed in the process of obtaining minimal cut sets. This option can reduce the number of minimal cut sets, save the computing time and assists the user in reviewing the result. (6) Computing time is monitored by the CUT-TD code so that it can prevent the running job from abnormally ending due to excessive CPU time and produce an intermediate result. The CUT-TD code has the ability to restart the calculation with use of the intermediate result. This report provides a users' manual for the CUT-TD code. (author)

    EXBURN-I has been developed for the analysis of LWR high burnup fuel behavior in normal operation and power transient conditions. In the high burnup region, phenomena occur which are different in quality from those expected for the extension of behaviors in the mid-burnup region. To analyze these phenomena, EXBURN-I has been formed by the incorporation of such new models as pellet thermal conductivity change, burnup-dependent FP gas release rate, and cladding oxide layer growth to the basic structure of low- and mid-burnup fuel analysis code FEMAXI-IV. The present report describes in detail the whole structure of the code, models, and materials properties. Also, it includes a detailed input manual and sample output, etc. (author). 55 refs.

    2010-01-01

    Information about primary user (PU) location is crucial in enabling several key capabilities in dynamic spectrum access networks, including improved spatio-temporal sensing, intelligent location-aware routing, as well as aiding spectrum policy enforcement. Compared to other proposed non-interactive localization algorithms, the weighted centroid localization (WCL) scheme uses only received signal strength information, which makes it simple and robust to variations in the propagation environment. In contrast to prior work, which focused mainly on proposing algorithmic variations and verifying their performance through simulations, in this paper we present the first theoretical framework for WCL performance analysis in terms of its localization error distribution parameterized by node density, node placement, shadowing variance and correlation distance. Using this analysis, we quantify the robustness of WCL to various physical conditions and provide guidelines, such as node placement, for practical deployment of...

  4. Sentiment Analysis of User-Generated Content on Drug Review Websites

    2015-03-01

    Full Text Available This study develops an effective method for sentiment analysis of user-generated content on drug review websites, which has not been investigated extensively compared to other general domains, such as product reviews. A clause-level sentiment analysis algorithm is developed since each sentence can contain multiple clauses discussing multiple aspects of a drug. The method adopts a pure linguistic approach of computing the sentiment orientation (positive, negative, or neutral of a clause from the prior sentiment scores assigned to words, taking into consideration the grammatical relations and semantic annotation (such as disorder terms of words in the clause. Experiment results with 2,700 clauses show the effectiveness of the proposed approach, and it performed significantly better than the baseline approaches using a machine learning approach. Various challenging issues were identified and discussed through error analysis. The application of the proposed sentiment analysis approach will be useful not only for patients, but also for drug makers and clinicians to obtain valuable summaries of public opinion. Since sentiment analysis is domain specific, domain knowledge in drug reviews is incorporated into the sentiment analysis algorithm to provide more accurate analysis. In particular, MetaMap is used to map various health and medical terms (such as disease and drug names to semantic types in the Unified Medical Language System (UMLS Semantic Network.

  8. User interaction with scatterplots on small screens--A comparative evaluation of geometric-semantic zoom and fisheye distortion.

    Büring, Thorsten; Gerken, Jens; Reiterer, Harald

    2006-01-01

    Existing information-visualization techniques that target small screens are usually limited to exploring a few hundred items. In this article we present a scatterplot tool for Personal Digital Assistants that allows the handling of many thousands of items. The application's scalability is achieved by incorporating two alternative interaction techniques: a geometric-semantic zoom that provides smooth transition between overview and detail, and a fisheye distortion that displays the focus and context regions of the scatterplot in a single view. A user study with 24 participants was conducted to compare the usability and efficiency of both techniques when searching a book database containing 7500 items. The study was run on a pen-driven Wacom board simulating a PDA interface. While the results showed no significant difference in task-completion times, a clear majority of 20 users preferred the fisheye view over the zoom interaction. In addition, other dependent variables such as user satisfaction and subjective rating of orientation and navigation support revealed a preference for the fisheye distortion. These findings partly contradict related research and indicate that, when using a small screen, users place higher value on the ability to preserve navigational context than they do on the ease of use of a simplistic, metaphor-based interaction style.

  16. Chronic illness and multimorbidity among problem drug users: a comparative cross sectional pilot study in primary care.

    LENUS (Irish Health Repository)

    Cullen, Walter

    2012-02-01

    BACKGROUND: Although multimorbidity has important implications for patient care in general practice, limited research has examined chronic illness and health service utilisation among problem drug users. This study aimed to determine chronic illness prevalence and health service utilisation among problem drug users attending primary care for methadone treatment, to compare these rates with matched \\'controls\\' and to develop and pilot test a valid study instrument. METHODS: A cross-sectional study of patients attending three large urban general practices in Dublin, Ireland for methadone treatment was conducted, and this sample was compared with a control group matched by practice, age, gender and General Medical Services (GMS) status. RESULTS: Data were collected on 114 patients. Fifty-seven patients were on methadone treatment, of whom 52(91%) had at least one chronic illness (other then substance use) and 39(68%) were prescribed at least one regular medication. Frequent utilisation of primary care services and secondary care services in the previous six months was observed among patients on methadone treatment and controls, although the former had significantly higher chronic illness prevalence and primary care contact rates. The study instrument facilitated data collection that was feasible and with minimal inter-observer variation. CONCLUSION: Multimorbidity is common among problem drug users attending general practice for methadone treatment.

    BACKGROUND: Although multimorbidity has important implications for patient care in general practice, limited research has examined chronic illness and health service utilisation among problem drug users. This study aimed to determine chronic illness prevalence and health service utilisation among problem drug users attending primary care for methadone treatment, to compare these rates with matched \\'controls\\' and to develop and pilot test a valid study instrument. METHODS: A cross-sectional study of patients attending three large urban general practices in Dublin, Ireland for methadone treatment was conducted, and this sample was compared with a control group matched by practice, age, gender and General Medical Services (GMS) status. RESULTS: Data were collected on 114 patients. Fifty-seven patients were on methadone treatment, of whom 52(91%) had at least one chronic illness (other then substance use) and 39(68%) were prescribed at least one regular medication. Frequent utilisation of primary care services and secondary care services in the previous six months was observed among patients on methadone treatment and controls, although the former had significantly higher chronic illness prevalence and primary care contact rates. The study instrument facilitated data collection that was feasible and with minimal inter-observer variation. CONCLUSION: Multimorbidity is common among problem drug users attending general practice for methadone treatment. Primary care may therefore have an important role in primary and secondary prevention of chronic illnesses among this population. This study offers a feasible study instrument for further work on this issue. (238 words).

    Genomic studies of bacteria, archaea and viruses have provided insights into the microbial world by unveiling potential functional capabilities and molecular pathways. However, the rate of discovery has been slower among microbial eukaryotes, whose genomes are larger and more complex. Transcriptomic approaches provide a cost-effective alternative for examining genetic potential and physiological responses of microbial eukaryotes to environmental stimuli. In this study, we generated and compared the transcriptomes of four globally-distributed, bloom-forming prymnesiophyte algae: Prymnesium parvum, Chrysochromulina brevifilum, Chrysochromulina ericina and Phaeocystis antarctica. Our results revealed that the four transcriptomes possess a set of core genes that are similar in number and shared across all four organisms. The functional classifications of these core genes using the euKaryotic Orthologous Genes (KOG) database were also similar among the four study organisms. More broadly, when the frequencies of different cellular and physiological functions were compared with other protists, the species clustered by both phylogeny and nutritional modes. Thus, these clustering patterns provide insight into genomic factors relating to both evolutionary relationships as well as trophic ecology. This paper provides a novel comparative analysis of the transcriptomes of ecologically important and closely related prymnesiophyte protists and advances an emerging field of study that uses transcriptomics to reveal ecology and function in protists.

    Fungi of the phylum Basidiomycota (basidiomycetes), make up some 37percent of the described fungi, and are important in forestry, agriculture, medicine, and bioenergy. This diverse phylum includes symbionts, pathogens, and saprotrophs including the majority of wood decaying and ectomycorrhizal species. To better understand the genetic diversity of this phylum we compared the genomes of 35 basidiomycetes including 6 newly sequenced genomes. These genomes span extremes of genome size, gene number, and repeat content. Analysis of core genes reveals that some 48percent of basidiomycete proteins are unique to the phylum with nearly half of those (22percent) found in only one organism. Correlations between lifestyle and certain gene families are evident. Phylogenetic patterns of plant biomass-degrading genes in Agaricomycotina suggest a continuum rather than a dichotomy between the white rot and brown rot modes of wood decay. Based on phylogenetically-informed PCA analysis of wood decay genes, we predict that that Botryobasidium botryosum and Jaapia argillacea have properties similar to white rot species, although neither has typical ligninolytic class II fungal peroxidases (PODs). This prediction is supported by growth assays in which both fungi exhibit wood decay with white rot-like characteristics. Based on this, we suggest that the white/brown rot dichotomy may be inadequate to describe the full range of wood decaying fungi. Analysis of the rate of discovery of proteins with no or few homologs suggests the value of continued sequencing of basidiomycete fungi.

    Comparative genome analysis is critical for the effectiveexploration of a rapidly growing number of complete and draft sequencesfor microbial genomes. The Integrated Microbial Genomes (IMG) system(img.jgi.doe.gov) has been developed as a community resource thatprovides support for comparative analysis of microbial genomes in anintegrated context. IMG allows users to navigate the multidimensionalmicrobial genome data space and focus their analysis on a subset ofgenes, genomes, and functions of interest. IMG provides graphicalviewers, summaries and occurrence profile tools for comparing genes,pathways and functions (terms) across specific genomes. Genes can befurther examined using gene neighborhoods and compared with sequencealignment tools.

  1. Construction QA/QC systems: comparative analysis

    International Nuclear Information System (INIS)

    An analysis which compares the quality assurance/quality control (QA/QC) systems adopted in the highway, nuclear power plant, and U.S. Navy construction areas with the traditional quality control approach used in building construction is presented. Full participation and support by the owner as well as the contractor and AE firm are required if a QA/QC system is to succeed. Process quality control, acceptance testing and quality assurance responsibilities must be clearly defined in the contract documents. The owner must audit these responsibilities. A contractor quality control plan, indicating the tasks which will be performed and the fact that QA/QC personnel are independent of project time/cost pressures should be submitted for approval. The architect must develop realistic specifications which consider the natural variability of material. Acceptance criteria based on the random sampling technique should be used. 27 refs

  2. Compare containment subcompartment analysis code evaluation

    International Nuclear Information System (INIS)

    Nuclear power plant subcompartment analyses are required to determine the containment pressure distribution that might result from a loss-of-coolant accident. The pressure distribution is used to calculate structural and mechanical design loads. The COMPARE code is used widely to perform subcompartment analysis. However, several simplifying assumptions are utilized to facilitate solution of the complex transient, two-phase, multidimensional flow problem. In particular, it is assumed that the flow is homogeneous, in thermodynamic equilibrium, and one-dimensional. In this study, these assumptions are evaluated by performing simplified transport and relaxation analyses. This results in definition of (a) geometric features and early-time periods that produce significant deviations from reality and (b) specific areas that require further study

    Fungi of the phylum Basidiomycota (basidiomycetes), make up some 37percent of the described fungi, and are important in forestry, agriculture, medicine, and bioenergy. This diverse phylum includes the mushrooms, wood rots, symbionts, and plant and animal pathogens. To better understand the diversity of phenotypes in basidiomycetes, we performed a comparative analysis of 35 basidiomycete fungi spanning the diversity of the phylum. Phylogenetic patterns of lignocellulose degrading genes suggest a continuum rather than a sharp dichotomy between the white rot and brown rot modes of wood decay. Patterns of secondary metabolic enzymes give additional insight into the broad array of phenotypes found in the basidiomycetes. We suggest that the profile of an organism in lignocellulose-targeting genes can be used to predict its nutritional mode, and predict Dacryopinax sp. as a brown rot; Botryobasidium botryosum and Jaapia argillacea as white rots.

    Propolis is a resinous mixture of substances collected and processed from various botanical sources by honeybees (Apis mellifera). We recently obtained Hawaiian propolis, the study of which, to our knowledge, has not been reported. The purpose of this study was to analyze the composition of Hawaiian propolis and to identify its botanical origin. A comparative analysis of Hawaiian and Okinawan propolis and of the glandular trichomes on Macaranga tanarius fruit (the botanical origin of Okinawan propolis) was performed using reversed-phase high-performance liquid chromatography coupled with high resolution-electrospray mass spectrometry. Hawaiian propolis contained nine prenylflavonoids that were also isolated from Okinawan propolis. In conclusion, we suggest that the botanical origin of Hawaiian propolis is M. tanarius, the same as that of Okinawan propolis. PMID:24689281

    Ras proteins are membrane bound signalling hubs that operate from both the cell surface and endomembrane compartments. However, the extent to which intracellular pools of Ras can contribute to cell signalling is debated. To address this, we have performed a global screen of compartmentalised Ras signalling. We find that whilst ER/Golgi- and endosomal-Ras only generate weak outputs, Ras localised to the mitochondria or Golgi significantly and distinctly influence both the abundance and phosphorylation of a wide range of proteins analysed. Our data reveal that ~80% of phosphosites exhibiting large (?1.5-fold) changes compared to control can be modulated by organellar Ras signalling. The majority of compartmentalised Ras-specific responses are predicted to influence gene expression, RNA splicing and cell proliferation. Our analysis reinforces the concept that compartmentalisation influences Ras signalling and provides detailed insight into the widespread modulation of responses downstream of endomembranous Ras signalling.

    Approximately 70 percent of all U.S. military training lands are located in arid and semi-arid areas. Training activities in such areas frequently adversely affect vegetation, damaging plants and reducing the resilience of vegetation to recover once disturbed. Fugitive dust resulting from a loss of vegetation creates additional problems for human health, increasing accidents due to decreased visibility, and increasing maintenance costs for roads, vehicles, and equipment. Diagnostic techniques are needed to identify thresholds of sustainable military use. A cooperative effort among U.S. Department of Energy, U.S. Department of Defense, and selected university scientists was undertaken to focus on developing new techniques for monitoring and mitigating military impacts in arid lands. This manual focuses on the development of new monitoring techniques that have been implemented at Fort Irwin, California. New mitigation techniques are described in a separate companion manual. This User's Manual is designed to address diagnostic capabilities needed to distinguish between various degrees of sustainable and nonsustainable impacts due to military training and testing and habitat-disturbing activities in desert ecosystems. Techniques described here focus on the use of high-resolution imagery and the application of image-processing techniques developed primarily for medical research. A discussion is provided about the measurement of plant biomass and shrub canopy cover in arid. lands using conventional methods. Both semiquantitative methods and quantitative methods are discussed and reference to current literature is provided. A background about the use of digital imagery to measure vegetation is presented.

    Vehicles powered by fuel cells operate more efficiently, more quietly, and more cleanly than internal combustion engines (ICEs). Furthermore, methanol-fueled fuel cell vehicles (FCVs) can utilize major elements of the existing fueling infrastructure of present-day liquid-fueled ICE vehicles (ICEVs). DOE has maintained an active program to stimulate the development and demonstration o fuel cell technologies in conjunction with rechargeable batteries in road vehicles. The purpose of this study is to identify and assess the availability of data on FCVs, and to develop a vehicle subsystem structure that can be used to compare both FCVs and ICEV, from a number of perspectives--environmental impacts, energy utilization, materials usage, and life cycle costs. This report focuses on methanol-fueled FCVs fueled by gasoline, methanol, and diesel fuel that are likely to be demonstratable by the year 2000. The comparative analysis presented covers four vehicles--two passenger vehicles and two urban transit buses. The passenger vehicles include an ICEV using either gasoline or methanol and an FCV using methanol. The FCV uses a Proton Exchange Membrane (PEM) fuel cell, an on-board methanol reformer, mid-term batteries, and an AC motor. The transit bus ICEV was evaluated for both diesel and methanol fuels. The transit bus FCV runs on methanol and uses a Phosphoric Acid Fuel Cell (PAFC) fuel cell, near-term batteries, a DC motor, and an on-board methanol reformer. 75 refs.

    2014-09-01

    Full Text Available Missing data is a frequent problem for researchers conducting exploratory factor analysis (EFA or reliability analysis. The SPSS FACTOR procedure allows users to select listwise deletion, pairwise deletion or mean substitution as a method for dealing with missing data. The shortcomings of these methods are well-known. Graham (2009 argues that a much better way to deal with missing data in this context is to use a matrix of expectation maximization (EM covariances(or correlations as input for the analysis. SPSS users who have the Missing Values Analysis add-on module can obtain vectors ofEM means and standard deviations plus EM correlation and covariance matrices via the MVA procedure. But unfortunately, MVA has no /MATRIX subcommand, and therefore cannot write the EM correlations directly to a matrix dataset of the type needed as input to the FACTOR and RELIABILITY procedures. We describe two macros that (in conjunction with an intervening MVA command carry out the data management steps needed to create two matrix datasets, one containing EM correlations and the other EM covariances. Either of those matrix datasets can then be used asinput to the FACTOR procedure, and the EM correlations can also be used as input to RELIABILITY. We provide an example that illustrates the use of the two macros to generate the matrix datasets and how to use those datasets as input to the FACTOR and RELIABILITY procedures. We hope that this simple method for handling missing data will prove useful to both students andresearchers who are conducting EFA or reliability analysis.

    A light water reactor fuel behavior analysis code FEMAXI-IV(Ver.2) was developed as an improved version of FEMAXI-IV. Development of FEMAXI-IV has been already finished in 1992, though a detailed structure and input manual of the code have not been open to users yet. Here, the basic theories and structure, the models and numerical solutions applied to FEMAXI-IV(Ver.2), and the material properties adopted in the code are described in detail. In FEMAXI-IV(Ver.2), programming bugs in previous FEMAXI-IV were eliminated, renewal of the pellet thermal conductivity was performed, and a model of thermal-stress restraint on FP gas release was incorporated. For facilitation of effective and wide-ranging application of the code, methods of input/output of the code are also described in detail, and sample output is included. (author)

  14. COMPETITIVENESS OF BOSNIA AND HERZEGOVINA – COMPARATIVE ANALYSIS

    2015-06-01

    Full Text Available Competitiveness or market competition is the basic regulatory mechanism of the market. Today, some economic theorists propose that the competitiveness actually measures the wealth of a society in another way, so it is very important that it contributes to innovation, improvement of the business and overall economic growth. Bosnia and Herzegovina is located close to the very bottom of the European countries according to the competitiveness of its economy. Occasionally it is possible to notice positive changes, but unfortunately they were not strong enough or continuous for achieving economic development or improving living standard. Benchmark analysis of competitiveness deepened the view of the overall movement of the BiH competitiveness and its key factors, as well as the comparison with the selected reference countries. So, the competitiveness of our economy in the period 2007-2015 is the main topic of this paper, with the basic hypothesis that BiH has a positive trend in competitiveness relative to comparable countries in the reporting period. The aim of the research is to determine the conditions, trends and underlying determinants of competitiveness of Bosnia and Herzegovina and state of our competitiveness in relation to comparative economies. Through application of standard scientific methodology, particularly methods of statistical analysis, we came to results that show that BiH economy had significant growth of competitiveness in most observed indicators, with minor variations in the period 2007-2014, while the level of variability in 2015 was so huge that we have been excluded from the Global Competitiveness Report for 2014-2015 year of the World Economic Forum. Although our country generally exhibits the lower performance than the comparative countries it is possible to perceive areas where we have strengths and potentials. The fact that the World Economic Forum, for the first time, has omitted Bosnia and Herzegovina from the Global Competitiveness Report 2014/2015, is an additional reason to re-examine all the factors that may affect the movements of competitiveness in BiH.

    The importance of including user's costs in Life-Cycle Cost-Benefit analysis of structures is discussed in this paper. This is especially for bridges of great importance. Repair or/and failure of a bridge will usually result in user costs greater than the repair or replacement costs of the bridge. For the society (and the user's) it is therefore of great importance that maintenance or replacement of a bridge is performed in such a way that all costs are minimized - not only the owners cost.

    Full Text Available In domains (as digital TV, smart home, and tangible interfaces that represent a new paradigm of interactivity, the decision of the most appropriate interaction design solution is a challenge. HCI researchers have promoted in their works the validation of design alternative solutions with users before producing the final solution. User experience with technology is a subject that has also gained ground in these works in order to analyze the appropriate solution(s. Following this concept, a study was accomplished under the objective of finding a better interaction solution for an application of mobile TV. Three executable applications of mobile TV prototypes were built. A Verbal Decision Analysis model was applied on the investigations for the favorite characteristics in each prototype based on the user’s experience and their intentions of use. This model led a performance of a qualitative analysis which objectified the design of a new prototype.

    In the last decade, the Internet has profoundly changed the delivery of healthcare. Medical websites for professionals and patients are playing an increasingly important role in providing the latest evidence-based knowledge for professionals, facilitating virtual patient support groups, and providing an invaluable information source for patients. Information seeking is the key user activity on the Internet. However, the discrepancy between what information is available and what the user is able to find has a profound effect on user satisfaction. The UK National electronic Library of Infection (NeLI, www.neli.org.uk) and its subsidiary projects provide a single-access portal for quality-appraised evidence in infectious diseases. We use this national portal, as test-bed for investigating our research questions. In this paper, we investigate actual and perceived user navigation behaviour that reveals important information about user perceptions and actions, in searching for information. Our results show: (i) all users were able to access information they were seeking; (ii) broadly, there is an agreement between "reported" behaviour (from questionnaires) and "observed" behaviour (from web logs), although some important differences were identified; (iii) both browsing and searching were equally used to answer specific questions and (iv) the preferred route for browsing for data on the NeLI website was to enter via the "Top Ten Topics" menu option. These findings provide important insights into how to improve user experience and satisfaction with health information websites.

    Myers, R. A.; Topp, D. A.; Delaney, R. A.

    1995-01-01

    The primary objective of this study was the development of a computational fluid dynamics (CFD) based turbomachinery airfoil analysis and design system, controlled by a graphical user interface (GUI). The computer codes resulting from this effort are referred to as the Turbomachinery Analysis and Design System (TADS). This document is intended to serve as a user's manual for the computer programs which comprise the TADS system. TADS couples a throughflow solver (ADPAC) with a quasi-3D blade-to-blade solver (RVCQ3D) in an interactive package. Throughflow analysis capability was developed in ADPAC through the addition of blade force and blockage terms to the governing equations. A GUI was developed to simplify user input and automate the many tasks required to perform turbomachinery analysis and design. The coupling of various programs was done in a way that alternative solvers or grid generators could be easily incorporated into the TADS framework.

    Liu, Huayong; Jiang, Shanshan; He, Tingting

    2011-11-01

    An advanced user-oriented summary extraction method for soccer video is proposed in this work. Firstly, an algorithm of user-oriented summary extraction for soccer video is introduced. A novel approach that integrates multimodal analysis, such as extraction and analysis of the stadium features, moving object features, audio features and text features is introduced. By these features the semantic of the soccer video and the highlight mode are obtained. Then we can find the highlight position and put them together by highlight degrees to obtain the video summary. The experimental results for sports video of world cup soccer games indicate that multimodal analysis is effective for soccer video browsing and retrieval.

    Knight, Norman F., Jr.

    2008-01-01

    Previously a user-defined material model for orthotropic bimodulus materials was developed for linear and nonlinear stress analysis of composite structures using either shell or solid finite elements within a nonlinear finite element analysis tool. Extensions of this user-defined material model to thermo-mechanical progressive failure analysis are described, and the required input data are documented. The extensions include providing for temperature-dependent material properties, archival of the elastic strains, and a thermal strain calculation for materials exhibiting a stress-free temperature.

  17. Comparative analysis of haplotype association mapping algorithms

    2006-02-01

    Full Text Available Abstract Background Finding the genetic causes of quantitative traits is a complex and difficult task. Classical methods for mapping quantitative trail loci (QTL in miceuse an F2 cross between two strains with substantially different phenotype and an interval mapping method to compute confidence intervals at each position in the genome. This process requires significant resources for breeding and genotyping, and the data generated are usually only applicable to one phenotype of interest. Recently, we reported the application of a haplotype association mapping method which utilizes dense genotyping data across a diverse panel of inbred mouse strains and a marker association algorithm that is independent of any specific phenotype. As the availability of genotyping data grows in size and density, analysis of these haplotype association mapping methods should be of increasing value to the statistical genetics community. Results We describe a detailed comparative analysis of variations on our marker association method. In particular, we describe the use of inferred haplotypes from adjacent SNPs, parametric and nonparametric statistics, and control of multiple testing error. These results show that nonparametric methods are slightly better in the test cases we study, although the choice of test statistic may often be dependent on the specific phenotype and haplotype structure being studied. The use of multi-SNP windows to infer local haplotype structure is critical to the use of a diverse panel of inbred strains for QTL mapping. Finally, because the marginal effect of any single gene in a complex disease is often relatively small, these methods require the use of sensitive methods for controlling family-wise error. We also report our initial application of this method to phenotypes cataloged in the Mouse Phenome Database. Conclusion The use of inbred strains of mice for QTL mapping has many advantages over traditional methods. However, there are also limitations in comparison to the traditional linkage analysis from F2 and RI lines. Application of these methods requires careful consideration of algorithmic choices based on both theoretical and practical factors. Our findings suggest general guidelines, though a complete evaluation of these methods can only be performed as more genetic data in complex diseases becomes available.

    2015-12-01

    User analysis job demands can exceed available computing resources, especially before major conferences. ATLAS physics results can potentially be slowed down due to the lack of resources. For these reasons, cloud research and development activities are now included in the skeleton of the ATLAS computing model, which has been extended by using resources from commercial and private cloud providers to satisfy the demands. However, most of these activities are focused on Monte-Carlo production jobs, extending the resources at Tier-2. To evaluate the suitability of the cloud-computing model for user analysis jobs, we developed a framework to launch an ATLAS user analysis cluster in a cloud infrastructure on demand and evaluated two solutions. The first solution is entirely integrated in the Grid infrastructure by using the same mechanism, which is already in use at Tier-2: A designated Panda-Queue is monitored and additional worker nodes are launched in a cloud environment and assigned to a corresponding HTCondor queue according to the demand. Thereby, the use of cloud resources is completely transparent to the user. However, using this approach, submitted user analysis jobs can still suffer from a certain delay introduced by waiting time in the queue and the deployed infrastructure lacks customizability. Therefore, our second solution offers the possibility to easily deploy a totally private, customizable analysis cluster on private cloud resources belonging to the university.

    Full Text Available The sovereign debt crisis and the new legal framework of European economic governance have forced most of the EU Countries to adopt stricter fiscal rules. In order to support budget decisions and fiscal policy choices on a strictly technical level, Independent Fiscal Institutions have often been set up in Europe. The present study aims to develop a comparative analysis of Independent Fiscal Institutions in order to better understand the role given to these public bodies in different countries. The effectiveness of so-called “fiscal watchdogs” depends on their independence and the reputation they are able to build. They are or become strong if their creation follows the path of the country’s constitutional traditions and there is compatibility with the specific political context. Taking into particular consideration some experiences (mostly European, the paper discusses the connections between introducing an Independent Fiscal Institution and reinforcing the activities of public policy evaluation, especially in Parliaments. The development of a culture of evaluation could in fact better ensure the accountability of Government, allowing legislative Assemblies to perform a more efficient oversight on all public policies, among which the most important is considered the fiscal one.

    This document presents a comparative analysis of site characteristics related to long-term safety for the two candidate sites for a final repository for spent nuclear fuel in Forsmark (municipality of Oesthammar) and in Laxemar (municipality of Oskarshamn) from the point of view of site selection. The analyses are based on the updated site descriptions of Forsmark /SKB 2008a/ and Laxemar /SKB 2009a/, together with associated updated repository layouts and designs /SKB 2008b and SKB 2009b/. The basis for the comparison is thus two equally and thoroughly assessed sites. However, the analyses presented here are focussed on differences between the sites rather than evaluating them in absolute terms. The document serves as a basis for the site selection, from the perspective of long-term safety, in SKB's application for a final repository. A full evaluation of safety is made for a repository at the selected site in the safety assessment SR-Site /SKB 2011/, referred to as SR-Site main report in the following

    We analyze the temporal behavior of Network Bright Points (NBPs), present in the solar atmosphere, using a set of data acquired during coordinated observations between ground-based observatories (mainly at the NSO/Sacramento Peak) and the Michelson Doppler Interferometer onboard SOHO. We find that, at any time during the observational sequence, all the NBPs visible in the NaD2 images are co-spatial within 1 arcsec with locations of enhanced magnetic field. In analogy with the Ca II K line, the NaD2 line center emission can be used as a proxy for magnetic structures. We also compare the oscillation properties of NBPs and internetwork areas. At photospheric levels no differences between the two structures are found in power spectra, but analysis of phase and coherence spectra suggests the presence of downward propagating waves in the internetwork. At chromospheric levels some differences are evident in the power spectrum between NBPs and internetwork. The power spectrum of NBPs at the Halpha core wavelength sho...

    Full Text Available The research developed in the present work is mainly aimed on comparative analysis of competitiveness in Romania and Bulgaria. We want to draw a warning, because the situation is even more worrying because, according to the latest official reports on global and regional competitiveness, Romania was exceeded by Bulgaria, which will have a negative impact on Romania's development in the medium and long term, unless urgent action is taken to redress situation. Although entry into the EU, competitiveness has become a national priority for both Romania and Bulgaria, this being transposed in national development programs and operational programs of the EU's competitiveness, the figures show that Romania had a very low absorption of European funds during 2007- 2013, two times less than Bulgaria absorbed. Target, set by the EU Strategy, is that by 2020, investment in research, development, innovation, made both government and the private sector, representing 2% or 1.5 % of GDP for Romania and Bulgaria. In these circumstances, Romania must develop macroeconomic policies to stimulate economic competitiveness, develop all regions, to attract foreign direct investment, external grants. Bulgaria has to face two major challenges: to accelerate the grow rate and to make it sustainable. Bulgaria has to ensure conditions for innovations and realization of human capital, including the development of the regions.

  3. A Comparative Analysis on Mining Frequent Itemsets

    2012-12-01

    Full Text Available Research on mining frequent itemsets is one of ` the emerging task in data mining.The purchasing of one product when another product is purchased represents an association rule. Association rules are useful for analyzing the customer behavior. It takes an important part in shopping basket data analysis, clustering. The FP-Growth and Apriori algorithm is the basic algorithm for mining association rules. This paper presents an efficient algorithm for mining frequent itemsets using Two Dimensional Transactions Reduction(TDTR approach which reduces the original database(D transactions to the reduced data base transactions D1 based on the min_sup count. Then for each item it finds the number of transactions that the item present and hence find the largest frequent itemset using the two dimensional approach. Using the largest item set property ,it finds the subset of frequent item sets. Thus TDTR approach reduces the number of scans in the database and hence improve the efficiency & accuracy by finding the number of association rules and reduces time to find the rules.This proposed approach compares the efficiency with traditional Apriori and FP-Growth algorithm.

    With the increasing prevalence and demand of large scale cloud computing environment, a researcher has to draw more attention towards the services provided by the CLOUD. As the access to the server is increasing, centralized and distributed computing architecture will produce bottlenecks data which affect the quality of cloud computing services and bring the huge support to users. In this paper we are going to propose certain vital aspects such as memory utilization, storage capacity to check the efficiency and performance of various clouds in cloud computing environment. This is based upon the static data. The proposed mechanism enables users to access memories in various systems depending on the predefined criteria. Selection method for accessing the memory of a resource is properly introduced in this paper. Our evaluation results show that the aggregation of various clouds is effective in indicating the better efficiency and also to reduce network traffic sent over cloud networks.

  12. A Methodology for Evaluating User Perceptions of the Delivery of ICT Services: a comparative study of six UK local authorities

    Directory of Open Access Journals (Sweden)

    2000-11-01

    Full Text Available Evaluating and managing the effective delivery of ICT services is an issue that has been brought into sharper relief recently. This has been particularly prevalent in the UK public sector where the growing emphasis on formalised client-contractor relationships, outsourcing and benchmarking (both between local authorities and between local authorities and private sector organisations has meant that the definition of service standards and agreeing performance criteria has attracted considerable practitioner attention. This research is based on 295 interviews conducted in six UK local authorities. The investigation used both gap analysis and perceptual mapping techniques to develop an understanding of the aspects of ICT service delivery that users' value most in conjunction with an assessment of how well they perceive their ICT department is performing on these criteria. The paper exposes considerable differences in the relative performance of the six local authorities from both the gap analysis and the perceptual mapping elements of the investigation. The methodology is shown to provide an effective way of identifying key performance issues from the user perspective and benchmarking service performance across organisations.

  13. Comparative analysis of planetary laser ranging concepts

    Dirkx, D.; Bauer, S.; Noomen, R.; Vermeersen, B. L. A.; Visser, P. N.

    2014-12-01

    Laser ranging is an emerging technology for tracking interplanetary missions, offering improved range accuracy and precision (mm-cm), compared to existing DSN tracking. The ground segment uses existing Satellite Laser Ranging (SLR) technology, whereas the space segment is modified with an active system. In a one-way system, such as that currently being used on the LRO spacecraft (Zuber et al., 2010), only an active detector is required on the spacecraft. For a two-way system, such as that tested by using the laser altimeter system on the MESSENGER spacecraft en route to Mercury (Smith et al., 2006), a laser transmitter system is additionally placed on the space segment, which will asynchronously fire laser pulses towards the ground stations. Although the one-way system requires less hardware, clock errors on both the space and ground segments will accumulate over time, polluting the range measurements. For a two-way system, the range measurements are only sensitive to clock errors integrated over the the two-way light time.We investigate the performance of both one- and two-way laser range systems by simulating their operation. We generate realizations of clock error time histories from Allan variance profiles, and use them to create range measurement error profiles. We subsequently perform the orbit determination process from this data to quanitfy the system's performance. For our simulations, we use two test cases: a lunar orbiter similar to LRO and a Phobos lander similar to the Phobos Laser Ranging concept (Turyshev et al., 2010). For the lunar orbiter, we include an empirical model for unmodelled non-gravitational accelerations in our truth model to include errors ihe dynamics. We include the estimation of clock parameters over a number of arc lengths for our simulations of the one-way range system and use a variety of state arc durations for the lunar orbiter simulations.We perform Monte Carlo simulations and generate true error distributions for both missions for various combinations of clock and state arc length. Thereby, we quantify the relative capabilities of the one- and two-way laser range systems. In addition, we study the optimal data analysis strategies for these missions, which we apply for LRO orbit determination. Finally, we compare the performance of the laser ranging systems with typical DSN tracking.

    Full Text Available Sera from infected injection drug users (IDU) have shown to have antibodies against synthetic human immunodeficiency virus-1 (HIV-1) envelope peptides more frequently. In this study, reactivity of 48 IDU plasma were compared to 60 plasmas obtained from sexually infected individuals (S). The overall [...] reactivity of plasma from IDU compared to S was higher, and the reactivity titers were much higher for IDU plasma than S. IDU plasma also showed a broader antibody response. The higher reactivity titers were observed mainly for the gp41 immunodominant epitope and V3 peptides corresponding to the consensus sequences of HIV-1 subtypes/variants prevalent in Brazil (B, F, C) indicating the specificity in the higher immune response of IDU.

    Recommender systems are becoming an indispensable application and re-shaping the world in e-commerce scopes. This paper reviews the major problems in the existing recommender systems and presents a tracking recommendation approach based on information of user's behavior and two-level property of items. A new recommendation model based the synergistic use of knowledge from repository, which includes user's behavior, and items property was constructed and utilizes the Formal Concept Analysis (FCA) mapping to guide a personalized recommendation for user. We simulate a prototype recommender system that can make the quality recommendation by tracking user's behavior for implementing the proposed approach and testing its performance. Experiments using two datasets show our strategy was more robust against the drawbacks and preponderate over traditional recommendation approaches in cold-start conditions.

    2004-01-01

    Full Text Available In its first part, the paper analyses the ambiguous nature of the book as a medium: its physical production and its distribution to the end user takes place on a market basis; on the other hand, its content is predominantly consumed in a sector that was at least in the continental Europe traditionally considered as public and non-profit making. This ambiguous nature of the book and with it the impact of the market on the organization of knowledge in book format remains a dark spot in contemporary book research. On the other hand, textbooks are considered as ephemera both in contemporary education and book studies. Therefore, research on textbooks publishing models could be considered as a blind-spot of contemporary social studies. As a consequence, in the majority of European countries, textbook publishing and the organization of the textbook market are considered as self-evident. Throughout a comparative analysis of textbook publishing models in small transitional and developed countries, the paper points out that this self-evident organization of the textbook market is always culturally determined. In its final part, the paper compares different models of textbook publishing and outlines the scenarios for the development of the Slovene textbook market.

  19. AUDITOR ROTATION - A CRITICAL AND COMPARATIVE ANALYSIS

    2011-12-01

    Full Text Available The present paper starts out from the challenge regarding auditor tenure launched in 2010 by the Green Paper of the European Commission Audit Policy: Lessons from the Crisis. According to this document, the European Commission speaks both in favor of the mandatory rotation of the audit firm, and in favor of the mandatory rotation of audit partners. Rotation is considered a solution to mitigate threats to independence generated by familiarity, intimidation and self-interest in the context of a long-term audit-client relationship. At international level, there are several studies on auditor rotation, both empirical (e.g. Lu and Sivaramakrishnan, 2009, Li, 2010, Kaplan and Mauldin, 2008, Jackson et al., 2008 and normative in nature (e.g. Marten et al., 2007, Muller, 2006 and Gelter, 2004. The objective of the present paper is to perform a critical and comparative analysis of the regulations on internal and external rotation in force at international level, in the European Union and in the United States of America. Moreover, arguments both in favor and against mandatory rotation are brought into discussion. With regard to the research design, the paper has a normative approach. The main findings are first of all that by comparison, all regulatory authorities require internal rotation at least in the case of public interest entities, while the external rotation is not in the focus of the regulators. In general, the most strict and detailed requirements are those issued by the Securities and Exchange Commission from the United States of America. Second of all, in favor of mandatory rotation speaks the fact that the auditor becomes less resilient in case of divergence of opinions between him and company management, less stimulated to follow his own interest, and more scrupulous in conducting the audit. However, mandatory rotation may also have negative consequences, thus the debate on the opportunity of this regulatory measure remains open-ended.

    In most of the western countries, car is the prevalent means of transport for local mobility. At the same time, sensitivity to environmental issues is increasing, correlated to the consciousness that carbon dioxide emissions have to be reduced. In regard to these two trends (individual mobility and public opinions favourable to a reduction of carbon emissions), energy-efficient vehicles will probably develop in the future-car manufacturers actually prepare new offers for the mass market. Comparable cases have occurred during the last decades-probably more modest but full of learning: some local authorities have promoted innovations based on electric vehicles in the 1990s, and some people have chosen this kind of cars for their daily travels. This article deals with these pioneers (This article comes from a communication at the ECEEE Summer Study, June 2009, Panel 6: Energy efficiency in transport and mobility.). Reporting studies carried out in 2006 and 2008, we intend to identify the reasons of this innovative modal choice, to show the difficulties that electric vehicle drivers then encountered and to analyse the patterns of use that governed their mobility and their use of electric vehicles.

    Mobile phone calling is one of the most widely used communication methods in modern society. The records of calls among mobile phone users provide us a valuable proxy for the understanding of human communication patterns embedded in social networks. Mobile phone users call each other forming a directed calling network. If only reciprocal calls are considered, we obtain an undirected mutual calling network. The preferential communication behavior between two connected users can be statistically tested and it results in two Bonferroni networks with statistically validated edges. We perform a comparative analysis of the statistical properties of four networks, which are constructed from the calling records of more than nine million individuals in Shanghai over a period of 110 days. We find that these networks share many common structural properties and also exhibit idiosyncratic features when compared with previously studied large mobile calling networks. The empirical findings provide us an intriguing picture o...

  8. Neutron activation analysis at the Californium User Facility for Neutron Science

    International Nuclear Information System (INIS)

    The Californium User Facility (CUF) for Neutron Science has been established to provide 252Cf-based neutron irradiation services and research capabilities including neutron activation analysis (NAA). A major advantage of the CUF is its accessibility and controlled experimental conditions compared with those of a reactor environment The CUF maintains the world's largest inventory of compact 252Cf neutron sources. Neutron source intensities of ? 1011 neutrons/s are available for irradiations within a contamination-free hot cell, capable of providing thermal and fast neutron fluxes exceeding 108 cm-2 s-1 at the sample. Total flux of ?109 cm-2 s-1 is feasible for large-volume irradiation rabbits within the 252Cf storage pool. Neutron and gamma transport calculations have been performed using the Monte Carlo transport code MCNP to estimate irradiation fluxes available for sample activation within the hot cell and storage pool and to design and optimize a prompt gamma NAA (PGNAA) configuration for large sample volumes. Confirmatory NAA irradiations have been performed within the pool. Gamma spectroscopy capabilities including PGNAA are being established within the CUF for sample analysis

    Full Text Available In this paper we analyze if simple indicators related to photo quality (brightness, sharpness, color palette and established content detection techniques (face detection can predict the success of photos in obtaining more “likes” from other users of photo-sharing social networks. This provides a unique look into the habits of users of such networks. The analysis was performed on 394.000 images downloaded from the social photo-sharing site Instagram, paired with a de-identified dataset of user liking activity, provided by a seller of a social-media mobile app. Two user groups were analyzed: all users in a two month period (N = 122.260 and a highly selective group (N = 3.982 of users that only like <10% of what they view. No correlation was found with any of the indicators using the whole (non-selective population, likely due to their bias towards earning virtual currency in exchange for liking. However, in selective group, small positive correlation was found between like ratio and image sharpness (r=0.09, p<0.0001 and small negative correlation between like ratio and the number of faces (r=-0.10, p<0.0001.

    2012-01-01

    A useful step towards better interpretation and analysis of the usage patterns is to formalize the semantics of the resources that users are accessing in the Web. We focus on this problem and present an approach for the semantic formalization of usage logs, which lays the basis for eective techniques of querying expressive usage patterns. We also present a query answering approach, which is useful to nd in the logs expressive patterns of usage behavior via formulation of semantic and temporal-based constraints. We have processed over 30 thousand user browsing sessions extracted from usage logs of DBPedia and Semantic Web Dog Food. All these events are formalized semantically using respective domain ontologies and RDF representations of the Web resources being accessed. We show the eectiveness of our approach through experimental results, providing in this way an exploratory analysis of the way users browse theWeb of Data.

    Full Text Available .This paper provides a QoS analysis of a dynamic, ubiquitous UMTS network scenario in the automotive context identi_ed in the ongoing EC HIDENETS project. The scenario comprises different types of mobile users, applications, traffic conditions, and outage events reducing the available network resources. Adopting a compositional modeling approach based on Stochastic Activity Networks (SAN formalism, we analyze the Quality of Service (QoS both from the users' perspective and from the mobile operator's one. The classical QoS analysis is enhanced by taking into account the congestion both caused by the outage events and by the varying traffic conditions. The impact of users' mobility on the selected QoS indicators is further investigated combining the SAN modelling approach with an ad-hoc mobility simulator, which also allows to re_ne the model representing the UMTS network behavior.

  17. Comparative analysis of seismic risk assessment methodology

    International Nuclear Information System (INIS)

    SRA methodologies are separated into SPSA and SMM. SPSA methodology that has been widely used for seismic risk analysis has two kinds of methodologies such as Zion method and SSMRP method. SPSA methodology is suitable to interfacing with the analysis of internal event. However, the results of SPSA have uncertainties because of uncertainties in seismic hazard analysis and subjective judgement. Zion method specially developed for commercial use is less expensive and less time consuming but more uncertain than SSMRP method, since the former performs the fragility analysis less in detail than the latter. SMM is impossible to interface with the analysis of internal event but the uncertainties that are occurred during seismic hazard analysis is reduced because of the screening using RLE (review level earthquake). Therefore, if SPSA-based SMM methodology is chosen to be developed, the results of SRA will be more reliable and it requires low costs and time. In addition, the new methodology will require the development of a new evaluating code for SRA. (Author) 26 refs., 25 figs., 16 tabs

    2014-04-01

    Full Text Available The purpose of this study is to understand which bibliographic data are the core elements of the user’s queries? What users’ viewpoints about resource descriptions using different metadata standards? What kinds of value-added items are the users’ favorite when they conduct a bibliographic search? What are users’ viewpoints about bibliographic records integrated with the Digital Archival and Institutional Repository resources through metadata interoperability methods? This research adopted experiments, observation and interviews. The sample subjects are drawn from 14 students of The Graduate Institute of Library and Information Science and College of Agriculture and Natural Resources. First of all, the researcher displayed the bibliographic records using original MARC from the library. Secondly, users compared the images of OPAC from the library with the format of DC and MODS transformed through the MarcEdit software. Additionally, the researcher conducted interviews to understand users’ viewpoints about using three metadata schemas to describe the same book. Finally, the researcher asked the degree of users’ satisfaction about using bibliographic records alone and bibliographic records integrated with the Digital Archival and Institutional Repository resources. The findings suggest that libraries could provide more value-added and comprehensive services of bibliographic records and information retrieval, in order for all kinds of resources to be fully utilized, which helps to meet the users’ information needs.

    2015-01-01

    Application of next-generation sequencing (NGS) methods for transcriptome analysis (RNA-seq) has become increasingly accessible in recent years and are of great interest to many biological disciplines including, eg, evolutionary biology, ecology, biomedicine, and computational biology. Although virtually any research group can now obtain RNA-seq data, only a few have the bioinformatics knowledge and computation facilities required for transcriptome analysis. Here, we present TRUFA (TRanscriptome User-Friendly Analysis), an open informatics platform offering a web-based interface that generates the outputs commonly used in de novo RNA-seq analysis and comparative transcriptomics. TRUFA provides a comprehensive service that allows performing dynamically raw read cleaning, transcript assembly, annotation, and expression quantification. Due to the computationally intensive nature of such analyses, TRUFA is highly parallelized and benefits from accessing high-performance computing resources. The complete TRUFA pipeline was validated using four previously published transcriptomic data sets. TRUFA's results for the example datasets showed globally similar results when comparing with the original studies, and performed particularly better when analyzing the green tea dataset. The platform permits analyzing RNA-seq data in a fast, robust, and user-friendly manner. Accounts on TRUFA are provided freely upon request at https://trufa.ifca.es. PMID:26056424

    2015-12-01

    This study examines the challenges of estimating risk-adjusted treatment costs in international comparative research, specifically in the European Health Care Outcomes, Performance, and Efficiency (EuroHOPE) project. We describe the diverse format of resource data and challenges of converting these data into resource use indicators that allow meaningful cross-country comparisons. The three cost indicators developed in EuroHOPE are then described, discussed, and applied. We compare the risk-adjusted mean treatment costs of acute myocardial infarction for four of the seven countries in the EuroHOPE project, namely, Finland, Hungary, Norway, and Sweden. The outcome of the comparison depends on the time perspective as well as on the particular resource use indicator. We argue that these complementary indicators add to our understanding of the variation in resource use across countries. Copyright © 2015 John Wiley & Sons, Ltd. PMID:26633865

    2011-07-01

    Full Text Available Abstract Background Practice guidelines (PGs are systematically developed statements intended to assist in patient and practitioner decisions. The AGREE II is the revised tool for PG development, reporting, and evaluation, comprised of 23 items, two global rating scores, and a new User's Manual. In this study, we sought to develop, execute, and evaluate the impact of two internet interventions designed to accelerate the capacity of stakeholders to use the AGREE II. Methods Participants were randomized to one of three training conditions. 'Tutorial'--participants proceeded through the online tutorial with a virtual coach and reviewed a PDF copy of the AGREE II. 'Tutorial + Practice Exercise'--in addition to the Tutorial, participants also appraised a 'practice' PG. For the practice PG appraisal, participants received feedback on how their scores compared to expert norms and formative feedback if scores fell outside the predefined range. 'AGREE II User's Manual PDF (control condition'--participants reviewed a PDF copy of the AGREE II only. All participants evaluated a test PG using the AGREE II. Outcomes of interest were learners' performance, satisfaction, self-efficacy, mental effort, time-on-task, and perceptions of AGREE II. Results No differences emerged between training conditions on any of the outcome measures. Conclusions We believe these results can be explained by better than anticipated performance of the AGREE II PDF materials (control condition or the participants' level of health methodology and PG experience rather than the failure of the online training interventions. Some data suggest the online tools may be useful for trainees new to this field; however, this requires further study.

  19. Aggregate Characterization of User Behavior in Twitter and Analysis of the Retweet Graph

    CERN Document Server

    Bild, David R; Dick, Robert P; Mao, Z Morley; Wallach, Dan S

    2014-01-01

    Most previous analysis of Twitter user behavior is focused on individual information cascades and the social followers graph. We instead study aggregate user behavior and the retweet graph with a focus on quantitative descriptions. We find that the lifetime tweet distribution is a type-II discrete Weibull stemming from a power law hazard function, the tweet rate distribution, although asymptotically power law, exhibits a lognormal cutoff over finite sample intervals, and the inter-tweet interval distribution is power law with exponential cutoff. The retweet graph is small-world and scale-free, like the social graph, but is less disassortative and has much stronger clustering. These differences are consistent with it better capturing the real-world social relationships of and trust between users. Beyond just understanding and modeling human communication patterns and social networks, applications for alternative, decentralized microblogging systems-both predicting real-word performance and detecting spam-are d...

    Full Text Available Chromosomal damage and apoptosis were analyzed in users of mouthwash and/or alcoholic beverages, using the micronucleus test on exfoliated oral mucosa cells. Samples from four groups of 20 individuals each were analyzed: three exposed groups (EG1, EG2 and EG3) and a control group (CG). EG1 comprised [...] mouthwash users; EG2 comprised drinkers, and EG3 users of both mouthwashes and alcoholic beverages. Cell material was collected by gently scraping the insides of the cheeks. Then the cells were fixed in a methanol/acetic acid (3:1) solution and stained and counterstained, respectively, with Schiff reactive and fast green. Endpoints were computed on 2,000 cells in a blind test. Statistical analysis showed that chromosomal damage and apoptosis were significantly higher in individuals of groups EG1 and EG3 than in controls (p

    Full Text Available Purpose: Register and compare anatomical changes, structural and quantitative found in optical coherence tomography Stratus and Topcon 3D in chronic users of chloroquine. Methods: Five patients were diagnosed with toxic "bull's eye" maculopathy was submitted to macular optical coherence tomography examination (Stratus and Topcon 3D. Results: Both tools demonstrated an increase reflectivity of choriocapillaris unit just foveal retinal pigment epithelium atrophy. However, Topcon 3D provided to all patients better description of the line corresponding to the transition between inner and outer segments of photoreceptors. Using the possibility of assembling threedimensional images and subtraction selective retinal layers, we found a lesion with a target that reflects the greater thickness of retinal pigment epithelium in central and parafoveal region that is matched to preserve macular photoreceptors. Conclusion: it was observed better resolution and faster image capture by Topcon 3D than Stratus OCT, that provided more detailed analysis of the line corresponding to transition between outer and inner segment of photoreceptors in macular region. With Topcon 3D, it was possible to evaluate soundly the thickness of retinal pigment epithelium in central and parafoveal region that caused an increase reflectivity of choriocapillaris creating a image with a target unpublished before.

    The aim of the study was to investigate media presentations of baby boomers as future care users. The Swedish baby boomer generation, born in the 1940s, and known as the '40s generation, has been characterized as youthful and powerful, and a question investigated in the study was whether boomers are supposed to display these characteristics as care users. We analyzed 481 articles in Swedish newspapers, published between 1995 and 2012, with a qualitative content analysis. The results showed that the '40s generation was predicted to become a new breed of demanding, self-aware care users. These claims were supported by descriptions of the formative events and typical characteristics of these individuals, which were then projected onto their future behavior as care users. Such projections tended to portray contemporary care users as passive, submissive, and partly responsible for problems associated with elder care. Consequently, approaches that focus on differences between cohorts need to incorporate a constructionist dimension to highlight the problem of generationism. PMID:26162728

    Full Text Available End-user development is an emerging computer science discipline that provides programming paradigms, techniques, and tools suitable for users not trained in software engineering. One of the techniques that allow ordinary computer users to develop their own applications without the need to learn a classic programming language is a GUI-level programming based on programming-by-demonstration. To build wizard-based tools that assist users in application development and to verify the correctness of user programs, a computer-supported method for GUI-level data dependency analysis is necessary. Therefore, formal model for GUI representation is needed. In this paper, we present a finite state machine for modeling the data dependencies between GUI controls and GUI actions. Furthermore, we present an algorithm for automatic construction of finite state machine for arbitrary GUI application. We show that proposed state aggregation scheme successfully manages state explosion in state machine construction algorithm, which makes the model applicable for applications with complex GUIs.

    Amaranth flour--a product of amaranth seeds processing--is a valuable industrial raw material that has an unique chemical composition and may be used for nutrition of people suffering from intolerance to traditional cereals protein, including celiac disease patients. The research aim was to study the composition of amaranth flour of two types compared with semolina which is traditionally used for nutrition by Russian population, as well as to compare the composition of milk amaranth flour porridge with milk semolina porridge. The composition of amaranth whole-ground flour and amaranth flour of premium grade processed from amaranth seeds grown in Voronezh region has been researched. It is to be noted that protein content in amaranth flour was 10.8-24.3% higher than in semolina, and its biological value and NPU-coefficient were higher by 22.65 and 46.51% respectively; lysine score in amaranth flour protein of premium grade came up to 107.54%, and in semolina protein only 40.95%. The level of digestible carbohydrates, including starch, was lower in amaranth flour than in semolina by 2.79-12.85 and 4.76-15.85% respectively, while fiber content was 15.5-30 fold higher. Fat content in amaranth flour of premium grade was 2,4 fold lower than in whole-ground amaranth flour but it was 45% higher than in semolina. The main advantage of amaranth flour protein compared to wheat protein is the predominance of albumins and globulins and a minimal content of prolamines and alpha-gliadin complete absence. The specifics of chemical composition allow the amaranth flour to be recommended for being included into nutrition of both healthy children and adults and also celiac disease patients. PMID:25059059

    Full Text Available The Geostationary Ocean Color Imager (GOCI is the first geostationary ocean color sensor in orbit that provides bio-optical properties from coastal and open waters around the Korean Peninsula at unprecedented temporal resolution. In this study, we compare the normalized water-leaving radiance (nLw products generated by the Naval Research Laboratory Automated Processing System (APS with those produced by the stand-alone software package, the GOCI Data Processing System (GDPS, developed by the Korean Ocean Research & Development Institute (KORDI. Both results are then compared to the nLw measured by the above water radiometer at the Ieodo site. This above-water radiometer is part of the Aerosol Robotic NETwork (AeroNET. The results indicate that the APS and GDPS processed  correlates well within the same image slot where the coefficient of determination (r2 is higher than 0.84 for all the bands from 412 nm to 745 nm. The agreement between APS and the AeroNET data is higher when compared to the GDPS results. The Root-Mean-Squared-Error (RMSE between AeroNET and APS data ranges from 0.24 [mW/(cm2sr?m] at 555 nm to 0.52 [mW/(cm2sr?m]  at 412 nm while RMSE between AeroNET and GDPS data ranges from 0.47 [mW/(cm2sr?m] at 443 nm to 0.69 [mW/(cm2sr?m]  at 490 nm.

    International Nuclear Information System (INIS)

    On behalf of the BMI (Federal German Ministry of the Interior), the BfG in 1981 again started an interlaboratory comparison (among 42 measuring points) on the topic of radionuclides in sediments. The study was intended to test the reliability of G?, G?/R? measurements in sedimentary samples under practical conditions. The comparative analyses again revealed a number of error sources, and errors could be corrected. This was achieved not least by a good cooperation among the participating laboratories who contributed a.o. very useful information and ideas. (orig./HP)

  8. Transversal analysis of public policies on user fees exemptions in six West African countries

    Science.gov (United States)

    2012-01-01

    Background While more and more West African countries are implementing public user fees exemption policies, there is still little knowledge available on this topic. The long time required for scientific production, combined with the needs of decision-makers, led to the creation in 2010 of a project to support implementers in aggregating knowledge on their experiences. This article presents a transversal analysis of user fees exemption policies implemented in Benin, Burkina Faso, Mali, Niger, Togo and Senegal. Methods This was a multiple case study with several embedded levels of analysis. The cases were public user fees exemption policies selected by the participants because of their instructive value. The data used in the countries were taken from documentary analysis, interviews and questionnaires. The transversal analysis was based on a framework for studying five implementation components and five actors’ attitudes usually encountered in these policies. Results The analysis of the implementation components revealed: a majority of State financing; maintenance of centrally organized financing; a multiplicity of reimbursement methods; reimbursement delays and/or stock shortages; almost no implementation guides; a lack of support measures; communication plans that were rarely carried out, funded or renewed; health workers who were given general information but not details; poorly informed populations; almost no evaluation systems; ineffective and poorly funded coordination systems; low levels of community involvement; and incomplete referral-evacuation systems. With regard to actors’ attitudes, the analysis revealed: objectives that were appreciated by everyone; dissatisfaction with the implementation; specific tensions between healthcare providers and patients; overall satisfaction among patients, but still some problems; the perception that while the financial barrier has been removed, other barriers persist; occasionally a reorganization of practices, service rationing due to lack of reimbursement, and some overcharging or shifting of resources. Conclusions This transversal analysis confirms the need to assign a great deal of importance to the implementation of user fees exemption policies once these decisions have been taken. It also highlights some practices that suggest avenues of future research. PMID:23167598

  10. A comparative analysis of capacity adequacy policies

    International Nuclear Information System (INIS)

    In this paper a stochastic dynamic optimization model is used to analyze the effect of different generation adequacy policies in restructured power systems. The expansion decisions of profit-maximizing investors are simulated under a number of different market designs: Energy Only with and without a price cap, Capacity Payment, Capacity Obligation, Capacity Subscription, and Demand Elasticity. The results show that the overall social welfare is reduced compared to a centralized social welfare optimization for all policies except Capacity Subscription and Demand Elasticity. In particular, an energy only market with a low price cap leads to a significant increase in involuntary load shedding. Capacity payments and obligations give additional investment incentives and more generating capacity, but also result in a considerable transfer of wealth from consumers to producers due to the capacity payments. Increased demand elasticity increases social welfare, but also results in a transfer from producers to consumers, compared to the theoretical social welfare optimum. In contrast, the capacity subscription policy increases the social welfare, and both producers and consumers benefit. This is possible because capacity subscription explicitly utilizes differences in consumers' preferences for uninterrupted supply. This advantage must be weighed against the cost of implementation, which is not included in the model.

    Wolfram, Schlimme; Markus, Burri; Bruno, Betschart; Hermann, Hecker.

    1994-06-01

    Full Text Available The chromatin of Trypanosoma congolense was analyzed by electron microscopy. The chromatin is organized as nucleosome filaments but does not form a 30 nm fiber. There are five groups of histones, including a histone H1-like protein, which has a molecular weight within the range of the core histones, [...] and is extremely hydrophilic. Weak histone-histone interaction, a typical feature of trypanosoma chromatin, was found. These results are similar to those for T. cruzi and T. b. brucei, but differ significantly from those for higher eukaryotes. The results confirm the model of trypanosome chromatin, and support the theory of their early separation from the other eukaryotes during the evolution. T. congolensis is an excellent model for chromatin research on trypanosomes, because it is easy to cultivate and its chromatin has, a relatively high stability, compared to that of other trypanosomes.

  14. Resilience and electricity systems: A comparative analysis

    International Nuclear Information System (INIS)

    Electricity systems have generally evolved based on the natural resources available locally. Few metrics exist to compare the security of electricity supply of different countries despite the increasing likelihood of potential shocks to the power system like energy price increases and carbon price regulation. This paper seeks to calculate a robust measure of national power system resilience by analysing each step in the process of transformation from raw energy to consumed electricity. Countries with sizeable deposits of mineral resources are used for comparison because of the need for electricity-intensive metals processing. We find that shifts in electricity-intensive industry can be predicted based on countries' power system resilience. - Highlights: ? We establish a resilience index measure for major electricity systems. ? We examine a range of OECD and developing nations electricity systems and their ability to cope with shocks. ? Robustness measures are established to show resilience of electricity systems.

    The CMTB Thwacker hardware operates as a testbed analogue for the Flight Thwacker and Sieve components of CHIMRA, a device on the Curiosity Rover. The sieve separates particles with a diameter smaller than 150 microns for delivery to onboard science instruments. The sieving behavior of the testbed hardware should be similar to the Flight hardware for the results to be meaningful. The elastodynamic behavior of both sieves was studied analytically using the Rayleigh Ritz method in conjunction with classical plate theory. Finite element models were used to determine the mode shapes of both designs, and comparisons between the natural frequencies and mode shapes were made. The analysis predicts that the performance of the CMTB Thwacker will closely resemble the performance of the Flight Thwacker within the expected steady state operating regime. Excitations of the testbed hardware that will mimic the flight hardware were recommended, as were those that will improve the efficiency of the sieving process.

    2009-01-01

    Uncovering the community structure exhibited by real networks is a crucial step towards an understanding of complex systems that goes beyond the local organization of their constituents. Many algorithms have been proposed so far, but none of them has been subjected to strict tests to evaluate their performance. Most of the sporadic tests performed so far involved small networks with known community structure and/or artificial graphs with a simplified structure, which is very uncommon in real systems. Here we test several methods against a recently introduced class of benchmark graphs, with heterogeneous distributions of degree and community size. The methods are also tested against the benchmark by Girvan and Newman and on random graphs. As a result of our analysis, three recent algorithms introduced by Rosvall and Bergstrom, Blondel et al. and Ronhovde and Nussinov, respectively, have an excellent performance, with the additional advantage of low computational complexity, which enables one to analyze large s...

  18. Comparative Analysis of Cystatin Superfamily in Platyhelminths

    2015-01-01

    The cystatin superfamily is comprised of cysteine proteinase inhibitors and encompasses at least 3 subfamilies: stefins, cystatins and kininogens. In this study, the platyhelminth cystatin superfamily was identified and grouped into stefin and cystatin subfamilies. The conserved domain of stefins (G, QxVxG) was observed in all members of platyhelminth stefins. The three characteristics of cystatins, the cystatin-like domain (G, QxVxG, PW), a signal peptide, and one or two conserved disulfide bonds, were observed in platyhelminths, with the exception of cestodes, which lacked the conserved disulfide bond. However, it is noteworthy that cestode cystatins had two tandem repeated domains, although the second tandem repeated domain did not contain a cystatin-like domain, which has not been previously reported. Tertiary structure analysis of Taenia solium cystatin, one of the cestode cystatins, demonstrated that the N-terminus of T. solium cystatin formed a five turn ?-helix, a five stranded ?-pleated sheet and a hydrophobic edge, similar to the structure of chicken cystatin. Although no conserved disulfide bond was found in T. solium cystatin, the models of T. solium cystatin and chicken cystatin corresponded at the site of the first disulfide bridge of the chicken cystatin. However, the two models were not similar regarding the location of the second disulfide bridge of chicken cystatin. These results showed that T. solium cystatin and chicken cystatin had similarities and differences, suggesting that the biochemistry of T. solium cystatin could be similar to chicken cystatin in its inhibitory function and that it may have further functional roles. The same results were obtained for other cestode cystatins. Phylogenetic analysis showed that cestode cystatins constituted an independent clade and implied that cestode cystatins should be considered to have formed a new clade during evolution.

  2. Comparative economic analysis: Anaerobic digester case study

    International Nuclear Information System (INIS)

    An economic guide is developed to assess the value of anaerobic digesters used on dairy farms. Two varieties of anaerobic digesters, a conventional mixed-tank mesophilic and an innovative earthen psychrophilic, are comparatively evaluated using a cost-effectiveness index. The two case study examples are also evaluated using three other investment merit statistics: simple payback period, net present value, and internal rate of return. Life-cycle savings are estimated for both varieties, with sensitivities considered for investment risk. The conclusion is that an earthen psychrophilic digester can have a significant economic advantage over a mixed-tank mesophilic digester because of lower capital cost and reduced operation and maintenance expenses. Because of this economic advantage, additional projects are being conducted in North Carolina to increase the rate of biogas utilization. The initial step includes using biogas for milk cooling at the dairy farm where the existing psychrophilic digester is located. Further, a new project is being initiated for electricity production with thermal reclaim at a swine operation

    Genome function is dynamically regulated in part by chromatin, which consists of the histones, non-histone proteins and RNA molecules that package DNA. Studies in Caenorhabditis elegans and Drosophila melanogaster have contributed substantially to our understanding of molecular mechanisms of genome function in humans, and have revealed conservation of chromatin components and mechanisms. Nevertheless, the three organisms have markedly different genome sizes, chromosome architecture and gene organization. On human and fly chromosomes, for example, pericentric heterochromatin flanks single centromeres, whereas worm chromosomes have dispersed heterochromatin-like regions enriched in the distal chromosomal 'arms', and centromeres distributed along their lengths. To systematically investigate chromatin organization and associated gene regulation across species, we generated and analysed a large collection of genome-wide chromatin data sets from cell lines and developmental stages in worm, fly and human. Here we present over 800 new data sets from our ENCODE and modENCODE consortia, bringing the total to over 1,400. Comparison of combinatorial patterns of histone modifications, nuclear lamina-associated domains, organization of large-scale topological domains, chromatin environment at promoters and enhancers, nucleosome positioning, and DNA replication patterns reveals many conserved features of chromatin organization among the three organisms. We also find notable differences in the composition and locations of repressive chromatin. These data sets and analyses provide a rich resource for comparative and species-specific investigations of chromatin composition, organization and function. PMID:25164756

    We have an unique opportunity to compare the magnetospheres of two non-magnetic planets as Mars and Venus with identical instrument sets Aspera-3 and Aspera-4 on board of the Mars Express and Venus Express missions. We have performed both statistical and case studies of properties of the magnetosheath ion flows and the flows of planetary ions behind both planets. We have shown that the general morphology of both magnetotails is generally identical. In both cases the energy of the light ( H+) and the heavy ( O+, etc.) ions decreases from the tail periphery (several keV) down to few eV in the tail center. At the same time the wake center of both planets is occupied by plasma sheet coincident with the current sheet of the tail. Both plasma sheets are filled by accelerated (500-1000 eV) heavy planetary ions. We report also the discovery of a new feature never observed before in the tails of non-magnetic planets: the plasma sheet is enveloped by consecutive layers of He+ and H+ with decreasing energies.

    Full Text Available AIM: To isolate and identify differentially expressed proteins between cancer and normal tissues of gastric cancer by two-dimensional electrophoresis (2-DE and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS.METHODS: Soluble fraction proteins of gastric cancer tissues and paired normal tissues were separated by 2-DE. The differentially expressed proteins were selected and identified by MALDI-TOF-MS and database search.RESULTS: 2-DE profiles with high resolution and reproducibility were obtained. Twenty-three protein spots were excised from sliver staining gel and digested in gel by trypsin, in which fifteen protein spots were identified successfully. Among the identified proteins, there were ten over-expressed and five under-expressed proteins in stomach cancer tissues compared with normal tissues.CONCLUSION: In this study, the well-resolved, reproducible 2-DE patterns of human gastric cancer tissue and paired normal tissue were established and optimized and certain differentially-expressed proteins were identified. The combined use of 2-DE and MS provides an effective approach to screen for potential tumor markers.

  6. CARBON SEQUESTRATION: A METHODS COMPARATIVE ANALYSIS

    International Nuclear Information System (INIS)

    All human activities are related with the energy consumption. Energy requirements will continue to rise, due to the modern life and the developing countries growth. Most of the energy demand emanates from fossil fuels. Fossil fuels combustion has negative environmental impacts, with the CO2 production to be dominating. The fulfillment of the Kyoto protocol criteria requires the minimization of CO2 emissions. Thus the management of the CO2 emissions is an urgent matter. The use of appliances with low energy use and the adoption of an energy policy that prevents the unnecessary energy use, can play lead to the reduction of carbon emissions. A different route is the introduction of ''clean'' energy sources, such as renewable energy sources. Last but not least, the development of carbon sequestration methods can be promising technique with big future potential. The objective of this work is the analysis and comparison of different carbon sequestration and deposit methods. Ocean deposit, land ecosystems deposit, geological formations deposit and radical biological and chemical approaches will be analyzed

    This paper presents a comparative analysis of the effects of economic policy instruments in promoting environmentally sustainable transport. Promoting environmentally sustainable transport is defined as follows: (1) Reducing the volume of motorised travel; (2) Transferring travel to modes generating less external effects, and (3) Modifying road user behaviour in a way that will reduce external effects of transport. External effects include accidents, congestion, traffic noise and emissions to ai...

  9. Alice Meets Bob: A Comparative Usability Study of Wireless Device Pairing Methods for a "Two-User" Setting

    CERN Document Server

    Kumar, Arun; Uzun, Ersin

    2009-01-01

    When users want to establish wireless communication between/among their devices, the channel has to be bootstrapped first. To prevent any malicious control of or eavesdropping over the communication, the channel is desired to be authenticated and confidential. The process of setting up a secure communication channel between two previously unassociated devices is referred to as "Secure Device Pairing". When there is no prior security context, e.g., shared secrets, common key servers or public key certificates, device pairing requires user involvement into the process. The idea usually involves leveraging an auxiliary human-perceptible channel to authenticate the data exchanged over the insecure wireless channel. We observe that the focus of prior research has mostly been limited to pairing scenarios where a single user controls both the devices. In this paper, we consider more general and emerging "two-user" scenarios, where two different users establish pairing between their respective devices. Although a num...

  10. Analysis of chromosomal aberrations, micronuclei and hematological disorders among workers of wireless communication instruments and cell phone (Mobile) users

    International Nuclear Information System (INIS)

    This study was carried out to investigate the hazardous effect of electromagnetic radiation (EMR) such as chromosomal aberration, disturbed micronucleus formation and hematological disorders that may detected among workers of wireless communication instruments and mobile phone users. Seven individuals ( 3 males and 4 females) of a central workers in the microwave unit of the wireless station and 7 users of Mobil phone (4 males and 3 females ) were volunteered to give blood samples. Chromosomes and micronucleus were prepared for cytogenetic analysis as well as blood film for differential count. The results obtained in the microwave group indicated that, the total summation of all types of aberrations (chromosomes and chromatid aberrations) had a frequency of 6. 14% for the exposed group, whereas, the frequency in the control group amounted to 1.57%. In Mobil phone users, the total summation of all types of aberrations(chromosome and chromatid aberrations) had a frequency of 4.43% for the exposed group and 1.71% for the control group. The incidence of the total number of micronuclei in the exposed microwave group was increased 4.3 folds as compared with those of the control group The incidence of the total number of micronuclei in the exposed mobile phone group was increased 2 fold as compared with those in the control group. On the other hand, normal ranges of total white blood cells counts were determined for mobile phone users but abnormalities in the differential counts of the different types of the white blood cells such as neutropenia, eosinophilia and lymphocytosis were observed in the individuals number 1,2,3,7 in microwave group

  15. An Irish Cross-Institutional User Needs Analysis of Undergraduate Programming

    Directory of Open Access Journals (Sweden)

    Eileen Mary Costelloe

    2006-07-01

    Full Text Available Research literature and practical experience of subject experts indicate that teaching programming to novices has proven challenging for both learner and lecturer. A number of difficulties arise when teaching novices to program. These ranges from the inadequacy of the undergraduate students’ problem-solving skills, problems with understanding programming constructs, to the complexity of the environments in which the students develop their solutions. This paper outlines a project which aims to address some of the challenges faced by novice programmers by providing them with an innovative learning tool, incorporating a set of Reusable Learning Objects (RLOs, based on sound pedagogical principles and encapsulated in a Constructivist Learning Environment (CLE. The Learning Objects will focus on the common areas of weaknesses that are determined by an Irish cross-institutional User Needs Analysis. The initial research activity was to conduct a User Needs Analysis, which was carried out in the three third level academic partner institutions and which will inform and direct the remainder of the research project. The User Needs Analysis confirmed that first year undergraduate students find programming the most challenging module they study. Programming constructs such as Arrays, Looping and Selection were shown to be the most problematic in semester one, and Methods and Polymorphism posing difficulties in semester two. Interestingly the students’ actual and perceived difficulties with the concepts were not in-line, with the students perceiving their difficulties to be less than they actually were. The students acknowledge that problem-solving abilities impacted on their performance but only 20% of students in one college admitted to thinking about their approach in designing programming solutions. The results of the User Needs Analysis directs the design and development of the RLOs and the learning tool.

  18. Large-System Analysis of Joint User Selection and Vector Precoding for Multiuser MIMO Downlink

    CERN Document Server

    Takeuchi, Keigo; Kawabata, Tsutomu

    2012-01-01

    Joint user selection (US) and vector precoding (US-VP) is proposed for multiuser multiple-input multiple-output (MU-MIMO) downlink. The main difference between joint US-VP and conventional US is that US depends on data symbols for joint US-VP, whereas conventional US is independent of data symbols. The replica method is used to analyze the performance of joint US-VP in the large-system limit, where the numbers of transmit antennas, users, and selected users tend to infinity while their ratios are kept constant. The analysis under the assumptions of replica symmetry (RS) and 1-step replica symmetry breaking (1RSB) implies that optimal data-independent US provides nothing but the same performance as random US in the large-system limit, whereas data-independent US is capacity-achieving as only the number of users tends to infinity. It is shown that joint US-VP can provide a substantial reduction of the energy penalty in the large-system limit. Consequently, joint US-VP outperforms separate US-VP in terms of the ...

  1. MONITORING POTENTIAL DRUG INTERACTIONS AND REACTIONS VIA NETWORK ANALYSIS OF INSTAGRAM USER TIMELINES

    2015-01-01

    Much recent research aims to identify evidence for Drug-Drug Interactions (DDI) and Adverse Drug reactions (ADR) from the biomedical scientific literature. In addition to this “Bibliome”, the universe of social media provides a very promising source of large-scale data that can help identify DDI and ADR in ways that have not been hitherto possible. Given the large number of users, analysis of social media data may be useful to identify under-reported, population-level pathology associated with DDI, thus further contributing to improvements in population health. Moreover, tapping into this data allows us to infer drug interactions with natural products—including cannabis—which constitute an array of DDI very poorly explored by biomedical research thus far. Our goal is to determine the potential of Instagram for public health monitoring and surveillance for DDI, ADR, and behavioral pathology at large. Most social media analysis focuses on Twitter and Facebook, but Instagram is an increasingly important platform, especially among teens, with unrestricted access of public posts, high availability of posts with geolocation coordinates, and images to supplement textual analysis. Using drug, symptom, and natural product dictionaries for identification of the various types of DDI and ADR evidence, we have collected close to 7000 user timelines spanning from October 2010 to June 2015. We report on 1) the development of a monitoring tool to easily observe user-level timelines associated with drug and symptom terms of interest, and 2) population-level behavior via the analysis of co-occurrence networks computed from user timelines at three different scales: monthly, weekly, and daily occurrences. Analysis of these networks further reveals 3) drug and symptom direct and indirect associations with greater support in user timelines, as well as 4) clusters of symptoms and drugs revealed by the collective behavior of the observed population. This demonstrates that Instagram contains much drug- and pathology specific data for public health monitoring of DDI and ADR, and that complex network analysis provides an important toolbox to extract health-related associations and their support from large-scale social media data.

    2007-01-01

    The need for home care will probably continue to increase over the next decade as one response to innovative health practices designed to help people receive services at home instead of in institutions. However, there are no data for determining whether home-care programmes can meet user needs. The objectives of the present study were to describe the functional autonomy profile of the users of public home-care programmes in Québec, Canada, and to compare the level of adequacy between required and provided services in public home-care programmes for older adults with disabilities. This study was based on a cross-sectional design from September to December 2002. The population studied consisted of all users of public home-care services in one administrative region in the province of Québec over this 3-month period. Each user was assessed with the Functional Autonomy Measurement System (SMAF) and then classified into one of the 14 Iso-SMAF profiles. The total number of hours of care required was determined using the median number of hours of nursing care, personal care and support services associated with each profile. For the sake of comparison with the services required, the services provided were calculated from an administrative databank that included statistics of the time spent by health professionals on caring for home-care users. The ratio of hours of services provided to the number of hours of services required by home-care users highlights a discrepancy between the services provided and user needs. The results of this study show the feasibility of describing users of public home-care programmes and the adequacy of services provided in relation to user needs. Based on these results, public home-care programmes in the province of Québec appear to be under-funded. PMID:17212620

  6. Transportation Routing Analysis Geographic Information System (WebTRAGIS) User's Manual

    International Nuclear Information System (INIS)

    In the early 1980s, Oak Ridge National Laboratory (ORNL) developed two transportation routing models: HIGHWAY, which predicts truck transportation routes, and INTERLINE, which predicts rail transportation routes. Both of these models have been used by the U.S. Department of Energy (DOE) community for a variety of routing needs over the years. One of the primary uses of the models has been to determine population-density information, which is used as input for risk assessment with the RADTRAN model, which is available on the TRANSNET computer system. During the recent years, advances in the development of geographic information systems (GISs) have resulted in increased demands from the user community for a GIS version of the ORNL routing models. In April 1994, the DOE Transportation Management Division (EM-261) held a Baseline Requirements Assessment Session with transportation routing experts and users of the HIGHWAY and INTERLINE models. As a result of the session, the development of a new GIS routing model, Transportation Routing Analysis GIS (TRAGIS), was initiated. TRAGIS is a user-friendly, GIS-based transportation and analysis computer model. The older HIGHWAY and INTERLINE models are useful to calculate routes, but they cannot display a graphic of the calculated route. Consequently, many users have experienced difficulty determining the proper node for facilities and have been confused by or have misinterpreted the text-based listing from the older routing models. Some of the primary reasons for the development of TRAGIS are (a) to improve the ease of selecting locations for routing, (b) to graphically display the calculated route, and (c) to provide for additional geographic analysis of the route

    Ratib, Osman M.; Huang, H. K.

    1989-05-01

    A multimodality picture archiving and communication system (PACS) is in routine clinical use in the UCLA Radiology Department. Several types workstations are currently implemented for this PACS. Among them, the Apple Macintosh II personal computer was recently chosen to serve as a desktop workstation for display and analysis of radiological images. This personal computer was selected mainly because of its extremely friendly user-interface, its popularity among the academic and medical community and its low cost. In comparison to other microcomputer-based systems the Macintosh II offers the following advantages: the extreme standardization of its user interface, file system and networking, and the availability of a very large variety of commercial software packages. In the current configuration the Macintosh II operates as a stand-alone workstation where images are imported from a centralized PACS server through an Ethernet network using a standard TCP-IP protocol, and stored locally on magnetic disk. The use of high resolution screens (1024x768 pixels x 8bits) offer sufficient performance for image display and analysis. We focused our project on the design and implementation of a variety of image analysis algorithms ranging from automated structure and edge detection to sophisticated dynamic analysis of sequential images. Specific analysis programs were developed for ultrasound images, digitized angiograms, MRI and CT tomographic images and scintigraphic images.

    1980-01-01

    A user guide and programmer documentation is provided for a system of PRIME 400 minicomputer programs. The system was designed to support loading analyses on the Tracking Data Relay Satellite System (TDRSS). The system is a scheduler for various types of data relays (including tape recorder dumps and real time relays) from orbiting payloads to the TDRSS. Several model options are available to statistically generate data relay requirements. TDRSS time lines (representing resources available for scheduling) and payload/TDRSS acquisition and loss of sight time lines are input to the scheduler from disk. Tabulated output from the interactive system includes a summary of the scheduler activities over time intervals specified by the user and overall summary of scheduler input and output information. A history file, which records every event generated by the scheduler, is written to disk to allow further scheduling on remaining resources and to provide data for graphic displays or additional statistical analysis.

  11. Discovering Latent Patterns from the Analysis of User-Curated Movie Lists

    CERN Document Server

    Greene, Derek

    2013-01-01

    User content curation is becoming an important source of preference data, as well as providing information regarding the items being curated. One popular approach involves the creation of lists. On Twitter, these lists might contain accounts relevant to a particular topic, whereas on a community site such as the Internet Movie Database (IMDb), this might take the form of lists of movies sharing common characteristics. While list curation involves substantial combined effort on the part of users, researchers have rarely looked at mining the outputs of this kind of crowdsourcing activity. Here we study a large collection of movie lists from IMDb. We apply network analysis methods to a graph that reflects the degree to which pairs of movies are "co-listed", that is, assigned to the same lists. This allows us to uncover a more nuanced grouping of movies that goes beyond categorisation schemes based on attributes such as genre or director.

  12. Transversal analysis of public policies on user fees exemptions in six West African countries

    2012-11-01

    Full Text Available Abstract Background While more and more West African countries are implementing public user fees exemption policies, there is still little knowledge available on this topic. The long time required for scientific production, combined with the needs of decision-makers, led to the creation in 2010 of a project to support implementers in aggregating knowledge on their experiences. This article presents a transversal analysis of user fees exemption policies implemented in Benin, Burkina Faso, Mali, Niger, Togo and Senegal. Methods This was a multiple case study with several embedded levels of analysis. The cases were public user fees exemption policies selected by the participants because of their instructive value. The data used in the countries were taken from documentary analysis, interviews and questionnaires. The transversal analysis was based on a framework for studying five implementation components and five actors’ attitudes usually encountered in these policies. Results The analysis of the implementation components revealed: a majority of State financing; maintenance of centrally organized financing; a multiplicity of reimbursement methods; reimbursement delays and/or stock shortages; almost no implementation guides; a lack of support measures; communication plans that were rarely carried out, funded or renewed; health workers who were given general information but not details; poorly informed populations; almost no evaluation systems; ineffective and poorly funded coordination systems; low levels of community involvement; and incomplete referral-evacuation systems. With regard to actors’ attitudes, the analysis revealed: objectives that were appreciated by everyone; dissatisfaction with the implementation; specific tensions between healthcare providers and patients; overall satisfaction among patients, but still some problems; the perception that while the financial barrier has been removed, other barriers persist; occasionally a reorganization of practices, service rationing due to lack of reimbursement, and some overcharging or shifting of resources. Conclusions This transversal analysis confirms the need to assign a great deal of importance to the implementation of user fees exemption policies once these decisions have been taken. It also highlights some practices that suggest avenues of future research.

  13. GUARDD: user-friendly MATLAB software for rigorous analysis of CPMG RD NMR data

    International Nuclear Information System (INIS)

    Molecular dynamics are essential for life, and nuclear magnetic resonance (NMR) spectroscopy has been used extensively to characterize these phenomena since the 1950s. For the past 15 years, the Carr-Purcell Meiboom-Gill relaxation dispersion (CPMG RD) NMR experiment has afforded advanced NMR labs access to kinetic, thermodynamic, and structural details of protein and RNA dynamics in the crucial μs-ms time window. However, analysis of RD data is challenging because datasets are often large and require many non-linear fitting parameters, thereby confounding assessment of accuracy. Moreover, novice CPMG experimentalists face an additional barrier because current software options lack an intuitive user interface and extensive documentation. Hence, we present the open-source software package GUARDD (Graphical User-friendly Analysis of Relaxation Dispersion Data), which is designed to organize, automate, and enhance the analytical procedures which operate on CPMG RD data (http://code.google.com/p/guardd/http://code.google.com/p/guardd/). This MATLAB-based program includes a graphical user interface, permits global fitting to multi-field, multi-temperature, multi-coherence data, and implements χ2-mapping procedures, via grid-search and Monte Carlo methods, to enhance and assess fitting accuracy. The presentation features allow users to seamlessly traverse the large amount of results, and the RD Simulator feature can help design future experiments as well as serve as a teaching tool for those unfamiliar with RD phenomena. Based on these innovative features, we expect that GUARDD will fill a well-defined gap in service of the RD NMR community.

    2005-06-01

    Full Text Available Abstract Background - Sequencing of EST and BAC end datasets is no longer limited to large research groups. Drops in per-base pricing have made high throughput sequencing accessible to individual investigators. However, there are few options available which provide a free and user-friendly solution to the BLAST result storage and data mining needs of biologists. Results - Here we describe NuclearBLAST, a batch BLAST analysis, storage and management system designed for the biologist. It is a wrapper for NCBI BLAST which provides a user-friendly web interface which includes a request wizard and the ability to view and mine the results. All BLAST results are stored in a MySQL database which allows for more advanced data-mining through supplied command-line utilities or direct database access. NuclearBLAST can be installed on a single machine or clustered amongst a number of machines to improve analysis throughput. NuclearBLAST provides a platform which eases data-mining of multiple BLAST results. With the supplied scripts, the program can export data into a spreadsheet-friendly format, automatically assign Gene Ontology terms to sequences and provide bi-directional best hits between two datasets. Users with SQL experience can use the database to ask even more complex questions and extract any subset of data they require. Conclusion - This tool provides a user-friendly interface for requesting, viewing and mining of BLAST results which makes the management and data-mining of large sets of BLAST analyses tractable to biologists.

    Directory of Open Access Journals (Sweden)

    Giovanni Strona

    2014-08-01

    Full Text Available Recent theoretical advances in nestedness analysis have led to the introduction of several alternative metrics to overcome most of the problems biasing the use of matrix 'temperature' calculated by Atmar's Nestedness Temperature Calculator. However, all of the currently available programs for nestedness analysis lack the user friendly appeal that has made the Nestedness Temperature Calculator one of the most popular community ecology programs. The software package NeD is an intuitive open source application for nestedness analysis that can be used online or locally under different operating systems. NeD is able to automatically handle different matrix formats, has batch functionalities and produces an output that can be easily copied and pasted to a spreadsheet. In addition to numerical results, NeD provides a graphic representation of the matrix under examination and of the corresponding maximally packed matrix. NeD allows users to select among the most used nestedness metrics, and to combine them with different null models. Integrating easiness of use with the recent theoretical advances in the field, NeD provides researchers not directly involved in theoretical debates with a simple yet robust statistical tool for a more conscious performance of nestedness analysis. NeD can be accessed at http: //purl.oclc.org/ned.

    2009-01-01

    A common assumption in the existing network coding literature is that the users are cooperative and non-selfish. However, this assumption can be violated in practice. In this paper, we analyze inter-session network coding in a wired network using game theory. We assume selfish users acting strategically to maximize their own utility, leading to a resource allocation game among users. In particular, we study the well-known butterfly network topology where a bottleneck link is shared by several network coding and routing flows. We prove the existence of a Nash equilibrium for a wide range of utility functions. We show that the number of Nash equilibria can be large (even infinite) for certain choices of system parameters. This is in sharp contrast to a similar game setting with traditional packet forwarding where the Nash equilibrium is always unique. We then characterize the worst-case efficiency bounds, i.e., the Price-of-Anarchy (PoA), compared to an optimal and cooperative network design. We show that by us...

    Full Text Available Abstract Background Injecting drug users (IDU are at increased risk of human immunodeficiency virus (HIV infection. Their HIV prevalence however varies from place to place and may not be directly linked with the level of individual risk. This study explores the relative importance of individual and community level characteristics in the practice of HIV-related risk behaviors in IDU in Hong Kong where the HIV prevalence has remained low at below 1%. Methods Methadone clinics were used as the channel for accessing drug users in Hong Kong. HIV-related risk factors in drug users attending these clinics were retrieved from a questionnaire routinely administered to newly admitted and readmitted clients, and assessed using logistic regression and multilevel analyses. Results Between 1999 and 2005, a total of 41196 person-admissions were recorded by 20 methadone clinics. Male gender, older age and new admissions in bigger clinics located in districts with older median age were more likely to have engaged in HIV related risk behaviors including heroin injection, needle sharing, unprotected sex and having multiple sex partners (p Conclusion Multilevel analysis is a useful adjunct for determining the association between risk behaviors and both individual and community factors in IDUs, which can be demonstrated even in low HIV prevalence settings.

  2. User's manual of a support system for human reliability analysis. JASPAHR Version 1.5

    International Nuclear Information System (INIS)

    Many kind of human reliability analysis (HRA) methods have been developed. However, analysts are required to be skillful so as to use them, and also required complicated works such as drawing event tree (ET) and calculation of uncertainty bounds. Moreover, each method is not so complete that only one method of them is not enough to evaluate human reliability. Therefore, a personal computer based support system JASPAHR for HRA has been developed to execute HRA practically and efficiently. The system supports HRAs with two different types of method, namely, simple method and detailed one. The former uses ASEP that is a simplified THERP-technique, and combined method of OAT and HRA-ET/DeBDA is used for the latter. Users can select a suitable method for their purpose. Human error probability data were collected and a database of them is provided to link with the support system. JASPAHR was improved such as the introduction of the INTENT method for misdiagnosis evaluation and the improvement of user interface. The report is a user's manual for modified JASPAHR (Ver. 1.5).

    2015-12-01

    AsyncStageOut (ASO) is a new component of the distributed data analysis system of CMS, CRAB, designed for managing users' data. It addresses a major weakness of the previous model, namely that mass storage of output data was part of the job execution resulting in inefficient use of job slots and an unacceptable failure rate at the end of the jobs. ASO foresees the management of up to 400k files per day of various sizes, spread worldwide across more than 60 sites. It must handle up to 1000 individual users per month, and work with minimal delay. This creates challenging requirements for system scalability, performance and monitoring. ASO uses FTS to schedule and execute the transfers between the storage elements of the source and destination sites. It has evolved from a limited prototype to a highly adaptable service, which manages and monitors the user file placement and bookkeeping. To ensure system scalability and data monitoring, it employs new technologies such as a NoSQL database and re-uses existing components of PhEDEx and the FTS Dashboard. We present the asynchronous stage-out strategy and the architecture of the solution we implemented to deal with those issues and challenges. The deployment model for the high availability and scalability of the service is discussed. The performance of the system during the commissioning and the first phase of production are also shown, along with results from simulations designed to explore the limits of scalability.

  10. User's manual and analysis methodology of probabilistic fracture mechanics analysis code PASCAL Ver.2 for reactor pressure vessel (Contract research)

    International Nuclear Information System (INIS)

    As a part of the aging structural integrity research for LWR components, the probabilistic fracture mechanics (PFM) analysis code PASCAL (PFM Analysis of Structural Components in Aging LWR) has been developed in JAEA. This code evaluates the conditional probabilities of crack initiation and fracture of a reactor pressure vessel (RPV) under transient conditions such as pressurized thermal shock (PTS). The development of the code has been aimed to improve the accuracy and reliability of analysis by introducing new analysis methodologies and algorithms considering the recent development in the fracture mechanics and computer performance. PASCAL Ver.1 has functions of optimized sampling in the stratified Monte Carlo simulation, elastic-plastic fracture criterion of the R6 method, crack growth analysis models for a semi-elliptical crack, recovery of fracture toughness due to thermal annealing and so on. Since then, under the contract between the Ministry of Economy, Trading and Industry of Japan and JAEA, we have continued to develop and introduce new functions into PASCAL Ver.2 such as the evaluation method for an embedded crack, KI database for a semi-elliptical crack considering stress discontinuity at the base/cladding interface, PTS transient database, and others. A generalized analysis method is proposed on the basis of the development of PASCAL Ver.2 and results of sensitivity analyses. Graphical user interface (GUI) including a generalized method as default values has been also developed for PASCAL Ver.2. This report provides the user's manual and theoretical background of PASCAL Ver.2. (author)

    Full Text Available Abstract Background Infectious disease is often the reason for intravenous drug users being seen in a clinical setting. The objective of this study was to evaluate the appropriateness of treatment and outcomes for this patient population in a hospital setting. Methods Retrospective study of all intravenous drug users hospitalized for treatment of infectious diseases and seen by infectious diseases specialists 1/2001–12/2006 at a university hospital. Treatment was administered according to guidelines when possible or to alternative treatment program in case of patients for whom adherence to standard protocols was not possible. Outcomes were defined with respect to appropriateness of treatment, hospital readmission, relapse and mortality rates. For statistical analysis adjustment for multiple hospitalizations of individual patients was made by using a generalized estimating equation. Results The total number of hospitalizations for infectious diseases was 344 among 216 intravenous drug users. Skin and soft tissue infections (n = 129, 37.5% of hospitalizations, pneumonia (n = 75, 21.8% and endocarditis (n = 54, 15.7% were most prevalent. Multiple infections were present in 25%. Treatment was according to standard guidelines for 78.5%, according to an alternative recommended program for 11.3%, and not according to guidelines or by the infectious diseases specialist advice for 10.2% of hospitalizations. Psychiatric disorders had a significant negative impact on compliance (compliance problems in 19.8% of hospitalizations in multiple logistic regression analysis (OR = 2.4, CI 1.1–5.1, p = 0.03. The overall readmission rate and relapse rate within 30 days was 13.7% and 3.8%, respectively. Both non-compliant patient behavior (OR = 3.7, CI 1.3–10.8, p = 0.02 and non-adherence to treatment guidelines (OR = 3.3, CI 1.1–9.7, p = 0.03 were associated with a significant increase in the relapse rate in univariate analysis. In 590 person-years of follow-up, 24.6% of the patients died: 6.4% died during hospitalization (1.2% infection-related and 13.6% of patients died after discharge. Conclusion Appropriate antibiotic therapy according to standard guidelines in hospitalized intravenous drug users is generally practicable and successful. In a minority alternative treatments may be indicated, although associated with a higher risk of relapse.

    The impact of climate change will resonate through a broad range of fields including public health, infrastructure, water resources, and many others. Long-term coordinated planning, funding, and action are required for climate change adaptation and mitigation. Unfortunately, widespread use of climate data (simulated and observed) in non-climate science communities is impeded by factors such as large data size, lack of adequate metadata, poor documentation, and lack of sufficient computational and visualization resources. We present ClimatePipes to address many of these challenges by creating an open source platform that provides state-of-the-art, user-friendly data access, analysis, and visualization for climate and other relevant geospatial datasets, making the climate data available to non-researchers, decision-makers, and other stakeholders. The overarching goals of ClimatePipes are: - Enable users to explore real-world questions related to climate change. - Provide tools for data access, analysis, and visualization. - Facilitate collaboration by enabling users to share datasets, workflows, and visualization. ClimatePipes uses a web-based application platform for its widespread support on mainstream operating systems, ease-of-use, and inherent collaboration support. The front-end of ClimatePipes uses HTML5 (WebGL, Canvas2D, CSS3) to deliver state-of-the-art visualization and to provide a best-in-class user experience. The back-end of the ClimatePipes is built around Python using the Visualization Toolkit (VTK, http://vtk.org), Climate Data Analysis Tools (CDAT, http://uv-cdat.llnl.gov), and other climate and geospatial data processing tools such as GDAL and PROJ4. ClimatePipes web-interface to query and access data from remote sources (such as ESGF). Shown in the figure is climate data layer from ESGF on top of map data layer from OpenStreetMap. The ClimatePipes workflow editor provides flexibility and fine grained control, and uses the VisTrails (http://www.vistrails.org) workflow engine in the backend.

  13. LISA package user guide. Part III: SPOP (Statistical POst Processor). Uncertainty and sensitivity analysis for model output. Program description and user guide

    International Nuclear Information System (INIS)

    This manual is subdivided into three parts. In the third part, the SPOP (Statistical POst Processor) code is described as a tool to perform Uncertainty and Sensitivity Analyses on the output of a User implemented model. It has been developed at the joint Research Centre of Ispra as part of the LISA package. SPOP performs Sensitivity Analysis (SA) and Uncertainty Analysis (UA) on a sample output from a Monte Carlo simulation. The sample is generated by the User and contains values of the output variable (in the form of a time series) and values of the input variables for a set of different simulations (runs), which are realised by varying the model input parameters. The User may generate the Monte Carlo sample with the PREP pre-processor, another module of the LISA package. The SPOP code is completely written in FORTRAN 77 using structured programming. Among the tasks performed by the code are the computation of Tchebycheff and Kolmogorov confidence bounds on the output variable (UA), and the use of effective non-parametric statistics to rank the influence of model input parameters (SA). The statistics employed are described in the present manual. 19 refs., 16 figs., 2 tabs. Note: This PART III is a revised version of the previous EUR report N.12700EN (1990)

    Full Text Available Compares three user research methods of studying real-world digital library usage within the context of the Variations and Variations2 digital music libraries at Indiana University. After a brief description of both digital libraries, each method is described and illustrated with findings from the studies. User satisfaction questionnaires were used in two studies, one of Variations (n=30 and the other of Variations2 (n=12. Second, session activity log files were examined for 175 Variations2 sessions using both quantitative and qualitative methods. The third method, contextual inquiry, is illustrated with results from field observations of four voice students' information usage patterns. The three methods are compared in terms of expertise required; time required to set up, conduct, and analyse resulting data; and the benefits derived. Further benefits are achieved with a mixed-methods approach, combining the strengths of the methods to answer questions lingering as a result of other methods.

    Comparative co-localization analysis of transcription factors (TFs) and epigenetic marks (EMs) in specific biological contexts is one of the most critical areas of ChIP-Seq data analysis beyond peak calling. Yet there is a significant lack of user-friendly and powerful tools geared towards co-localization analysis based exploratory research. Most tools currently used for co-localization analysis are command line only and require extensive installation procedures and Linux expertise. Online tools partially address the usability issues of command line tools, but slow response times and few customization features make them unsuitable for rapid data-driven interactive exploratory research. We have developed PAPST: Peak Assignment and Profile Search Tool, a user-friendly yet powerful platform with a unique design, which integrates both gene-centric and peak-centric co-localization analysis into a single package. Most of PAPST's functions can be completed in less than five seconds, allowing quick cycles of data-driven hypothesis generation and testing. With PAPST, a researcher with or without computational expertise can perform sophisticated co-localization pattern analysis of multiple TFs and EMs, either against all known genes or a set of genomic regions obtained from public repositories or prior analysis. PAPST is a versatile, efficient, and customizable tool for genome-wide data-driven exploratory research. Creatively used, PAPST can be quickly applied to any genomic data analysis that involves a comparison of two or more sets of genomic coordinate intervals, making it a powerful tool for a wide range of exploratory genomic research. We first present PAPST's general purpose features then apply it to several public ChIP-Seq data sets to demonstrate its rapid execution and potential for cutting-edge research with a case study in enhancer analysis. To our knowledge, PAPST is the first software of its kind to provide efficient and sophisticated post peak-calling ChIP-Seq data analysis as an easy-to-use interactive application. PAPST is available at https://github.com/paulbible/papst and is a public domain work. PMID:25970601

    When users want to establish wireless communication between/among their devices, the channel has to be bootstrapped first. To prevent any malicious control of or eavesdropping over the communication, the channel is desired to be authenticated and confidential. The process of setting up a secure communication channel between two previously unassociated devices is referred to as "Secure Device Pairing". When there is no prior security context, e.g., shared secrets, common key servers or public ...

    Full Text Available The demand for Internet services and network resources in Educational networks are increasing rapidly. Specifically, the revolution of web 2.0 “also referred to as the Read-Write Web” has changed the way of information exchange and distribution. Although web 2.0 has gained attraction in all sectors of the education industry, but it results in high-traffic loads on networks which often leads to the Internet users’ dissatisfaction. Therefore, analyzing Internet traffic becomes an urgent need to provide high-quality service, monitoring bandwidth usage. In this study, we focus on analyzing the Internet traffic in Universiti Utara Malaysia (UUM main campus. We performed measurement analysis form the application level characteristics based on users’ preferences. A total of three methodological steps are carried out to meet the objective of this study namely data collection, data analysis and data presentation. The finding shows that social networks are the most web applications visited in UUM. These findings lead to facilitate the enhancement of Educational network performance and Internet bandwidth strategies.

  2. User Decisions in a (Partly) Digital World : Comparing Digital Piracy to Legal Alternatives for Film and Music

    DEFF Research Database (Denmark)

    Veitch, Rob; Constantiou, Ioanna

    2012-01-01

    Technologies enabling digital piracy have expanded the variety of options available to users when deciding how to access a product. As a result, access-mode decisions for film and music are broader than for other goods where the piracy option is not as prevalent. This paper presents a model of access-mode decisions for film and music which integrates elements of previous digital piracy models and expands upon them to reflect the decision’s complexity. We depict the access-mode decision as being influenced by the user’s product desire, price perceptions, perceived risks, internal regulators of behaviour, resources and legal availability. We test the model for film and music using causal data of access-mode decisions collected from students at two Danish universities. Our findings indicate that the economic considerations of price perception and legal availability are the most consistent factors in influencing the access-mode decision across different legal options. The paper concludes with an outline for future research.

    The attributes of social ecological systems affect the management of commons. Strengthening and enhancing social capital and the enforcement of rules and sanctions aid in the collective action of communities in forest fire management. Using a set of variables drawn from previous studies on the management of commons, we conducted a study across 20 community forest user groups in Central Siwalik, Nepal, by dividing the groups into two categories based on the type and level of their forest fire management response. Our study shows that the collective action in forest fire management is consistent with the collective actions in other community development activities. However, the effectiveness of collective action is primarily dependent on the complex interaction of various variables. We found that strong social capital, strong enforcement of rules and sanctions, and users' participation in crafting the rules were the major variables that strengthen collective action in forest fire management. Conversely, users' dependency on a daily wage and a lack of transparency were the variables that weaken collective action. In fire-prone forests such as the Siwalik, our results indicate that strengthening social capital and forming and enforcing forest fire management rules are important variables that encourage people to engage in collective action in fire management.

  4. COMPARATIVE ANALYSIS OF CONGESTION CONTROL MODELS FOR CELLULAR WIRELESS NETWORK

    Directory of Open Access Journals (Sweden)

    2015-08-01

    Full Text Available Cellular wireless systems like GSM suffer from congestion resulting in overall system degradation and poor service delivery. When the traffic demand in a geographical area is high, the input traffic rate will exceed thecapacity of the output lines. This work focused on homogenous wireless network (the network traffic and resource dimensioning that are statistically identical such that the network performance evaluation can be reduced to a system with single cell and a single traffic type. Such system can employa queuing model to evaluate the performance metric of a cell in terms of blocking probability. Five congestion control models were compared in the work to ascertain their peculiarities, they are Erlang B, Erlang C, Engset (cleared, Engset (buffered, and Bernoulli. To analyze the system, an aggregate onedimensional Markov chain wasderived, such that it describes a call arrival process under the assumption that it is Poisson distributed. The models were simulated and their results show varying performances, however the Bernoulli model (Pb5 tends to show a situation that allows more users access to the system and the congestion level remain unaffected despite increase in the number of users and the offered traffic into the system.

  5. Computational methods for comparative analysis of plant small RNAs.

    Science.gov (United States)

    Mahalingam, Gayathri; Meyers, Blake C

    2010-01-01

    Small RNAs play an important role in plant development, stress responses, and epigenetic regulation, primarily through their role in transcriptional and post-transcriptional silencing of specific target genes and loci. Most if not all plants utilize these small RNA signaling networks. We have developed a deep-sequencing based dataset of plant small RNAs, based on the hypothesis that comparisons among the complex pool of small RNAs from diverse plants will identify novel types of conserved, regulated, or species-specific molecules. A database containing upward of hundreds of millions of plant small RNA sequences is being created for comparative analyses. This small RNA database will allow the experimental characterization of the majority of the biologically important small RNAs for a range of plant species. This database can be accessed from our website (http://smallrna.udel.edu/). A variety of web-based tools have been developed for analyses of these data. Here, we focus on these tools, and we describe how the users can implement these tools to analyze and interpret the small RNA data and how the users could use similar approaches for other sets of plant small RNAs from diverse species.

    Full Text Available Inpainting is an art of modifying the digital image in such a way that the modifications/alterations are undetectable to an observer who is unknown of the original image. Applications of this technique include restoration of damaged photographs & films, removal of superimposed text, removal/replacement of unwanted objects. After the user selects a region to be inpainted the algorithm automatically fills in these holes by data sampled from remainder of the image. In past the problem of inpainting was addressed by two classes of algorithms (i “diffusion based inpainting” and (ii “texture synthesis”. Further extensive research has undergone in this field which resulted in variety of inpainting techniques. In this paper we will compare Fragment based [2] and Exemplar based [1] inpainting techniques.

  18. User friendly analysis of MR investigations of the cerebral perfusion: Windows trademark -based image processing

    International Nuclear Information System (INIS)

    Purpose: Quick and user-friendly analysis of perfusion and diffusion weighted MRI by means of interactive computer software. Method: A Windows trademark -based software was developed for analysis of perfusion (PWI) and diffusion (DWI) MR imaging. The computer program was developed in the programming language C++ using optimized algorithms, so that a high computing speed on Win95/98/NT systems is achieved. The established SVD algorithms of Oestergaard et al. for quantitative perfusion analysis were implemented. Results: Perfusion parameter maps of the cerebral blood flow (rCBF), the mean transit time (MTT) and the cerebral blood volume (rCBV) in consideration of the arterial input function (AIF) can be calculated and visualized using color tables. Additionally, the calculation of ''time-to-peak'' maps (TTP) and of maps of the percentage change in signal intensity (PC) is possible. The analysis of n = 10 normal persons shows perfusion values that agree with those found in the literature. Discussion: With the computer program developed here color-coded perfusion parameter maps can be calculated easily. Because of the high computing speed it is possible to get information about tissue perfusion on the basis of the large MR data sets even in acute investigations. (orig.)

  19. Bitmap indices for fast end-user physics analysis in ROOT

    International Nuclear Information System (INIS)

    Most physics analysis jobs involve multiple selection steps on the input data. These selection steps are called cuts or queries. A common strategy to implement these queries is to read all input data from files and then process the queries in memory. In many applications the number of variables used to define these queries is a relative small portion of the overall data set therefore reading all variables into memory takes unnecessarily long time. In this paper we describe an integration effort that can significantly reduce this unnecessary reading by using an efficient compressed bitmap index technology. The primary advantage of this index is that it can process arbitrary combinations of queries very efficiently, while most other indexing technologies suffer from the 'curse of dimensionality' as the number of queries increases. By integrating this index technology with the ROOT analysis framework, the end-users can benefit from the added efficiency without having to modify their analysis programs. Our performance results show that for multi-dimensional queries, bitmap indices outperform the traditional analysis method up to a factor of 10

  20. User's manuals of probabilistic fracture mechanics analysis code for aged piping, PASCAL-SP

    International Nuclear Information System (INIS)

    As a part of research on the material degradation and structural integrity assessment for aged LWR components, a PFM (Probabilistic Fracture Mechanics) analysis code PASCAL-SP (PFM Analysis of Structural Components in Aging LWR - Stress Corrosion Cracking at Welded Joints of Piping) has been developed. This code evaluates the failure probabilities at welded joints of aged piping by a Monte Carlo method. PASCAL-SP treats stress corrosion cracking (SCC) and fatigue crack growth in piping, according to the approaches of NISA and JSME FFS Code. The development of the code has been aimed to improve the accuracy and reliability of analysis by introducing new analysis methodologies and algorithms considering the latest knowledge in the SCC assessment and fracture criteria of piping. In addition, the accuracy of flaw detection and sizing at in-service inspection and residual stress distribution were modeled based on experimental data and introduced into PASCAL-SP. This code has been developed for a cross-check use by the regulatory body in Japan. In addition to this, this code can also be used for a research purpose by researchers in academia and industries. This report provides the user's manual and theoretical background of the code. (author)

    The growing awareness that human communications and social interactions are assuming a stratified structure, due to the availability of multiple techno-communication channels, including online social networks, mobile phone calls, short messages (SMS) and e-mails, has recently led to the study of multidimensional networks, as a step further the classical Social Network Analysis. A few papers have been dedicated to develop the theoretical framework to deal with such multiplex networks and to analyze some example of multidimensional social networks. In this context we perform the first study of the multiplex mobile social network, gathered from the records of both call and text message activities of millions of users of a large mobile phone operator over a period of 12 weeks. While social networks constructed from mobile phone datasets have drawn great attention in recent years, so far studies have dealt with text message and call data, separately, providing a very partial view of people sociality expressed on p...

    Raghavan, Prabhakar

    By blending principles from mechanism design, algorithms, machine learning and massive distributed computing, the search industry has become good at optimizing monetization on sound scientific principles. This represents a successful and growing partnership between computer science and microeconomics. When it comes to understanding how online users respond to the content and experiences presented to them, we have more of a lacuna in the collaboration between computer science and certain social sciences. We will use a concrete technical example from image search results presentation, developing in the process some algorithmic and machine learning problems of interest in their own right. We then use this example to motivate the kinds of studies that need to grow between computer science and the social sciences; a critical element of this is the need to blend large-scale data analysis with smaller-scale eye-tracking and "individualized" lab studies.

    2015-09-01

    The aim of this study was to investigate the relationship between methamphetamine (MA) use history and segmental hair analysis (1 and 3cm sections) and whole hair analysis results in Korean MA users in rehabilitation programs. Hair samples were collected from 26 Korean MA users. Eleven of the 26 subjects used cannabis with MA and two used cocaine, opiates, and MDMA with MA. Self-reported single dose of MA from the 26 subjects ranged from 0.03 to 0.5g/one time. Concentrations of MA and its metabolite amphetamine (AP) in hair were determined by gas chromatography mass spectrometry (GC/MS) after derivatization. The method used was well validated. Qualitative analysis from all 1cm sections (n=154) revealed a good correlation between positive or negative results for MA in hair and self-reported MA use (69.48%, n=107). In detail, MA results were positive in 66 hair specimens of MA users who reported administering MA, and MA results were negative in 41 hair specimens of MA users who denied MA administration in the corresponding month. Test results were false-negative in 10.39% (n=16) of hair specimens and false-positive in 20.13% (n=31) of hair specimens. In false positive cases, it is considered that after MA cessation it continued to be accumulated in hair still, while in false negative cases, self-reported histories showed a small amount of MA use or MA use 5-7 months previously. In terms of quantitative analysis, the concentrations of MA in 1 and 3cm long hair segments and in whole hair samples ranged from 1.03 to 184.98 (mean 22.01), 2.26 to 89.33 (mean 18.71), and 0.91 to 124.49 (mean 15.24)ng/mg, respectively. Ten subjects showed a good correlation between MA use and MA concentration in hair. Correlation coefficient (r) of 7 among 10 subjects ranged from 0.71 to 0.98 (mean 0.85). Four subjects showed a low correlation between MA use and MA concentration in hair. Correlation coefficient (r) of 4 subjects ranged from 0.36 to 0.55. Eleven subjects showed a poor correlation between MA use and MA concentration in hair. Correlation between MA use and MA concentration in hair of remaining one subject could not be determined or calculated. In this study, the correlation between accurate MA use histories obtained by psychiatrists and well-trained counselors and MA concentrations in hair was shown. This report provides objective scientific findings that should considerably aid the interpretation of forensic results and of the results of trials related to MA use. PMID:26197349

  11. CRITICA: coding region identification tool invoking comparative analysis

    Science.gov (United States)

    Badger, J. H.; Olsen, G. J.; Woese, C. R. (Principal Investigator)

    1999-01-01

    Gene recognition is essential to understanding existing and future DNA sequence data. CRITICA (Coding Region Identification Tool Invoking Comparative Analysis) is a suite of programs for identifying likely protein-coding sequences in DNA by combining comparative analysis of DNA sequences with more common noncomparative methods. In the comparative component of the analysis, regions of DNA are aligned with related sequences from the DNA databases; if the translation of the aligned sequences has greater amino acid identity than expected for the observed percentage nucleotide identity, this is interpreted as evidence for coding. CRITICA also incorporates noncomparative information derived from the relative frequencies of hexanucleotides in coding frames versus other contexts (i.e., dicodon bias). The dicodon usage information is derived by iterative analysis of the data, such that CRITICA is not dependent on the existence or accuracy of coding sequence annotations in the databases. This independence makes the method particularly well suited for the analysis of novel genomes. CRITICA was tested by analyzing the available Salmonella typhimurium DNA sequences. Its predictions were compared with the DNA sequence annotations and with the predictions of GenMark. CRITICA proved to be more accurate than GenMark, and moreover, many of its predictions that would seem to be errors instead reflect problems in the sequence databases. The source code of CRITICA is freely available by anonymous FTP (rdp.life.uiuc.edu in/pub/critica) and on the World Wide Web (http:/(/)rdpwww.life.uiuc.edu).

    Abstract Background Genome browsers are a common tool used by biologists to visualize genomic features including genes, polymorphisms, and many others. However, existing genome browsers and visualization tools are not well-suited to perform meaningful comparative analysis among a large number of genomes. With the increasing quantity and availability of genomic data, there is an increased burden to provide useful visualization and analysis tools for comparison of multiple collinear genomes suc...

    Full Text Available In recent years the number of companies that use WMS on its storage operation has increased. However, a great part of organizations that adopt this system has difficulties in the implementation process or in fully exploit its resources. In this context, this research aims to analyze the WMS system, identifying the key barriers inherent in its implementation process, the benefits and features curently offered to the market, as well as the trends to the tool development. This analysis was performed through the method of multicase study under the perspective of two system developers and three users. Based on the content analysis of the informations from literature review, the semi-structered interviews and the documentary analysis performed was possible to identify as the main difficulties in the process of system implementation the flaws in registration of products and addresses, mapping of logistics processes, the staff training and cultural work change. Regarding the system benefits, stands out the better operational control and the stock accuracy improvement. Finally the trends for the tool improvement involve linking the system with tablets and smartphones, integrations with RFID technology and customized reports generation.

    The seismic analysis code, SONATINA-2V, has been developed to analyze the behavior of the HTTR core graphite components under seismic excitation. The SONATINA-2V code is a two-dimensional computer program capable of analyzing the vertical arrangement of the HTTR graphite components, such as fuel blocks, replaceable reflector blocks, permanent reflector blocks, as well as their restraint structures. In the analytical model, each block is treated as rigid body and is restrained by dowel pins which restrict relative horizontal movement but allow vertical and rocking motions between upper and lower blocks. Moreover, the SONATINA-2V code is capable of analyzing the core vibration behavior under both simultaneous excitations of vertical and horizontal directions. The SONATINA-2V code is composed of the main program, pri-processor for making the input data to SONATINA-2V and post-processor for data processing and making the graphics from analytical results. Though the SONATINA-2V code was developed in order to work in the MSP computer system of Japan Atomic Energy Research Institute (JAERI), the computer system was abolished with the technical progress of computer. Therefore, improvement of this analysis code was carried out in order to operate the code under the UNIX machine, SR8000 computer system, of the JAERI. The users manual for seismic analysis code, SONATINA-2V, including pri- and post-processor is given in the present report. (author)

  18. C language program analysis system (CLAS) part 1: graphical user interface (GUI)

    International Nuclear Information System (INIS)

    CLAS (C Language Program Analysis System) is a reverse engineering tool intended for use in the verification and validation (V and V) phase of software programs developed in the ANSI C language. From the source code, CLAS generates data pertaining to two conceptual models of software programs viz., Entity-Relationship (E-R) model and Control Flow Graphs (CFG) model. Browsing tools within CLAS, make use of this data, to provide different graphical views of the project. Static analysis tools have been developed earlier for analysing assembly language programs. CLAS is a continuation of this work to provide automated support in analysis of ANSI C language programs. CLAS provides an integrated Graphical User Interface (GUI) based environment under which programs can be analysed into the above mentioned models and the analysed data can be viewed using the browsing tools. The GUI of CLAS is implemented using an OPEN LOOK compliant tool kit XVIEW on Sun SPARC IPC workstation running Sun OS 4.1.1 rev. B. This report describes the GUI of CLAS. CLAS is also expected to be useful in other contexts which may involve understanding architecture/structure of already developed C language programs. Such requirements can arise while carrying out activities like code modification, parallelising etc. (author). 5 refs., 13 figs., 1 appendix

    Availing services provided via the Internet became a widely accepted means in organising one's life. Beside others, eLearning goes with this trend as well. But, while employing Internet service makes life more convenient, at the same time, it raises risks with respect to the protection of the users' privacy. This paper analyses the attitudes of eLearning users towards their privacy by, initially, pointing out terminology and legal issues connected with privacy. Further, the concept and implementation as well as a result analysis of a conducted study is presented, which explores the problem area from different perspectives. The paper will show that eLearning users indeed care for the protection of their personal information when using eLearning services. However, their attitudes and behaviour slightly differ. In conclusion, we provide first approaches of assisting possibilities for users how to resolve the difference of requirements and their actual activities with respect to privacy protection.

    From a liberal perspective, pluralism and viewpoint diversity are seen as a necessary condition for a well-functioning democracy. Recently, there have been claims that viewpoint diversity is diminishing in online social networks, putting users in a "bubble", where they receive political information which they agree with. The contributions from our investigations are fivefold: (1) we introduce different dimensions of the highly complex value viewpoint diversity using political theory; (2) we provide an overview of the metrics used in the literature of viewpoint diversity analysis; (3) we operationalize new metrics using the theory and provide a framework to analyze viewpoint diversity in Twitter for different political cultures; (4) we share our results for a case study on minorities we performed for Turkish and Dutch Twitter users; (5) we show that minority users cannot reach a large percentage of Turkish Twitter users. With the last of these contributions, using theory from communication scholars and philoso...

  1. Comparable analysis methodology of CCHP based on distributed energy system

    International Nuclear Information System (INIS)

    Highlights: • A comparable assessment methodology on DES-based CCHP is proposed. • Energy cost of low valued heat consumed by CCHP is calculated based on energy grade. • DES-based hot-water-driven cooling system is more efficient than electric chillers. - Abstract: Energy and environmental issues have become increasingly prominent in the world. Distributed energy systems (DESs) and the combined cooling, heating, and power (CCHP) have been applied in the world. However, the evaluation of DESs and CCHP performance based on primary energy consumption is in dispute. Moreover, pursuing high performance of separate cooling/heating system is not beneficial for popularizing low-exergy cooling/heating technology in the field of DES in China. This study uses the pure-power-generation working condition of the DES as a baseline condition to conduct comparable analysis on DES-based CCHP according to energy grade. It is found that equivalent power consumption of steam and hot water consumed for CCHP is the power-generation capacity reduction of the DES compared with the baseline condition of the DES. DES-based steam and hot-water heating systems can save comparable energy cost (a sum of the equivalent and the direct power consumptions) by approximately 72% and 98%, respectively, compared with natural-gas-fired boilers. Hot-water-driven and steam-driven absorption cooling system based on the DES reach comparable coefficient of performances (a ratio of cooling capacity to comparable energy cost) of approximately 11.4 and 5.7. Thus, the proposed analysis methodology uses the power-generation capacity as benchmark to conduct energy grade analysis, and can more comparably and reasonably identify energy-saving capability of DES-based CCHP

  2. Initial Implementation of a comparative Data Analysis Ontology

    2009-01-01

    Full Text Available Comparative analysis is used throughout biology. When entities under comparison (e.g. proteins, genomes, species are related by descent, evolutionary theory provides a framework that, in principle, allows N-ary comparisons of entities, while controlling for non-independence due to relatedness. Powerful software tools exist for specialized applications of this approach, yet it remains under-utilized in the absence of a unifying informatics infrastructure. A key step in developing such an infrastructure is the definition of a formal ontology. The analysis of use cases and existing formalisms suggests that a significant component of evolutionary analysis involves a core problem of inferring a character history, relying on key concepts: “Operational Taxonomic Units” (OTUs, representing the entities to be compared; “character-state data” representing the observations compared among OTUs; “phylogenetic tree”, representing the historical path of evolution among the entities; and “transitions”, the inferred evolutionary changes in states of characters that account for observations. Using the Web Ontology Language (OWL, we have defined these and other fundamental concepts in a Comparative Data Analysis Ontology (CDAO. CDAO has been evaluated for its ability to represent token data sets and to support simple forms of reasoning. With further development, CDAO will provide a basis for tools (for semantic transformation, data retrieval, validation, integration, etc. that make it easier for software developers and biomedical researchers to apply evolutionary methods of inference to diverse types of data, so as to integrate this powerful framework for reasoning into their research.

    Full Text Available The adequacy of user models depends mainly on the accuracy and precision of information that is retrieved to the user. The real challenge in user modelling studies is due to the inadequacy of data, improper use of techniques, noise within the data and imprecise nature of human behavior. For the best results of user modelling, one should choose an appropriate way to do it i.e. by selecting the best suitable approach for the desired domain. Machine learning and Soft computing Techniques have the ability to handle the uncertainty and are extensively being used for user modeling purpose. This paper reviews various approaches of user modeling and critically analyzes the machine learning and soft computing techniques that have successfully captured and formally modelled the human behavior.

    The strategic and contemporary importance of e-governance has been recognized across the world. In India too, various ministries of Govt. of India and State Governments have taken e-governance initiatives to provide e-services to citizens and the business they serve. To achieve the mission objectives, and make such e-governance initiatives successful it would be necessary to improve the trust and confidence of the stakeholders. It is assumed that the delivery of government services will share the same public network information that is being used in the community at large. In particular, the Internet will be the principal means by which public access to government and government services will be achieved. To provide the security measures main aim is to identify user's access requirement for the stakeholders and then according to the models of Nath's approach. Based on this analysis, the Govt. can also make standards of security based on the e-governance models. Thus there will be less human errors and bias. This analysis leads to the security architecture of the specific G2C application.

  13. User-based and Cognitive Approaches to Knowledge Organization : A Theoretical Analysis of the Research Literature.

    DEFF Research Database (Denmark)

    HjŘrland, Birger

    2013-01-01

    In the 1970s and 1980s, forms of user-based and cognitive approaches to knowledge organization came to the forefront as part of the overall development in library and information science and in the broader society. The specific nature of userbased approaches is their basis in the empirical studies of users or the principle that users need to be involved in the construction of knowledge organization systems. It might seem obvious that user-friendly systems should be designed on user studies or user involvement, but extremely successful systems such as Apple’s iPhone, Dialog’s search system and Google’s PageRank are not based on the empirical studies of users. In knowledge organization, the Book House System is one example of a system based on user studies. In cognitive science the important WordNet database is claimed to be based on psychological research. This article considers such examples. The role of the user is often confused with the role of subjectivity. Knowledge organization systems cannot be objective and must therefore, by implication, be based on some kind of subjectivity. This subjectivity should, however, be derived from collective views in discourse communities rather than be derived from studies of individuals or from the study of abstract minds.

    2014-01-01

    The availability of several whole genome sequences makes comparative analyses possible. In primate genomes, the priority of transposable elements (TEs) is significantly increased because they account for ~45% of the primate genomes, they can regulate the gene expression level, and they are associated with genomic fluidity in their host genomes. Here, we developed the BLAST-like alignment tool (BLAT) based comparative analysis for transposable elements (BLATCAT) program. The BLATCAT program can compare specific regions of six representative primate genome sequences (human, chimpanzee, gorilla, orangutan, gibbon, and rhesus macaque) on the basis of BLAT and simultaneously carry out RepeatMasker and/or Censor functions, which are widely used Windows-based web-server functions to detect TEs. All results can be stored as a HTML file for manual inspection of a specific locus. BLATCAT will be very convenient and efficient for comparative analyses of TEs in various primate genomes.

    The Hybrid Science Data System (HySDS) scalably powers the ingestion, metadata extraction, cataloging, high-volume data processing, and publication of the geodetic data products for the Advanced Rapid Imaging & Analysis for Monitoring Hazard (ARIA-MH) project at JPL. HySDS uses a heterogeneous set of worker nodes from private & public clouds as well as virtual & bare-metal machines to perform every aspect of the traditional science data system. For our science data users, the forefront of HySDS is the facet search interface, FacetView, which allows them to browse, filter, and access the published products. Users are able to explore the collection of product metadata information and apply multiple filters to constrain the result set down to their particular interests. It allows them to download these faceted products for further analysis and generation of derived products. However, we have also employed a novel approach to faceting where it is also used to apply constraints for custom monitoring of products, system resources, and triggers for automated data processing. The power of the facet search interface is well documented across various domains and its usefulness is rooted in the current state of existence of metadata. However, user needs usually extend beyond what is currently present in the data system. A user interested in synthetic aperture radar (SAR) data over Kilauea will download them from FacetView but would also want email notification of future incoming scenes. The user may even want that data pushed to a remote workstation for automated processing. Better still, these future products could trigger HySDS to run the user's analysis on its array of worker nodes, on behalf of the user, and ingest the resulting derived products. We will present our findings in integrating an ancillary, user-defined, system-driven processing system for HySDS that allows users to define faceted rules based on facet constraints and triggers actions when new SAR data products arrive that match the constraints. We will discuss use cases where users have defined rules for the automated generation of InSAR derived products: interferograms for California and Kilauea, time-series analyses, and damage proxy maps. These findings are relevant for science data system development of the proposed NASA-ISRO SAR mission.

    In this paper, we propose an algorithm for color and texture analysis for dermoscopic images of human skin based on Haar wavelets, Local Binary Patterns (LBP) and Histogram Analysis. This approach is a modification of «7-point checklist» clinical method. Thus, that is an "absolute" diagnostic method because one is using only features extracted from tumor's ROI (Region of Interest), which can be selected manually and/or using a special algorithm. We propose additional features extracted from the same image for comparative analysis of tumor and healthy skin. We used Euclidean distance, Cosine similarity, and Tanimoto coefficient as comparison metrics between color and texture features extracted from tumor's and healthy skin's ROI separately. A classifier for separating melanoma images from other tumors has been built by SVM (Support Vector Machine) algorithm. Classification's errors with and without comparative features between skin and tumor have been analyzed. Significant increase of recognition quality with comparative features has been demonstrated. Moreover, we analyzed two modes (manual and automatic) for ROI selecting on tumor and healthy skin areas. We have reached 91% of sensitivity using comparative features in contrast with 77% of sensitivity using the only "absolute" method. The specificity was the invariable (94%) in both cases.

    Elvik, Rune; Ramjerdi, Farideh

    2014-01-01

    This paper presents a comparative analysis of the effects of economic policy instruments in promoting environmentally sustainable transport. Promoting environmentally sustainable transport is defined as follows: (1) Reducing the volume of motorised travel; (2) Transferring travel to modes generating less external effects, and (3) Modifying road user behaviour in a way that will reduce external effects of transport. External effects include accidents, congestion, traffic noise and emissions to air. Four economic policy instruments are compared: (1) Prices of motor fuel; (2) Congestion charges; (3) Toll schemes; (4) Reward systems giving incentives to reduce driving or change driver behaviour. The effects of these policy instruments are stated in terms of elasticities. All four economic policy instruments have negative elasticities, which means that they do promote environmentally sustainable transport. Long-term elasticities tend to be larger than short term elasticities. The long-term elasticities of reward systems are unknown. (C) 2014 Elsevier Ltd. All rights reserved.

    2015-05-01

    The comparative analysis of two Phytolacca americana DOPA dioxygenases (PaDOD1 and PaDOD2) that may be involved in betalain biosynthesis was carried out. The recombinant protein of PaDOD catalyzed the conversion of DOPA to betalamic acid, whereas DOD activity was not detected in PaDOD2 in vitro. The role of DOD genes is discussed in the evolutionary context using phylogenetic analysis, suggesting that DOD might have been duplicated early in evolution and that accumulation of base substitutions could have led to the different characteristics of DODs within the betalain-producing Caryophyllales.

  1. An Empirical Study on User-oriented Association Analysis of Library Classification Schemes

    Directory of Open Access Journals (Sweden)

    Hsiao-Tieh Pu

    2002-12-01

    Full Text Available Library classification schemes are mostly organized based on disciplines with a hierarchical structure. From the user point of view, some highly related yet non-hierarchical classes may not be easy to perceive in these schemes. This paper is to discover hidden associations between classes by analyzing users’ usage of library collections. The proposed approach employs collaborative filtering techniques to discover associated classes based on the circulation patterns of similar users. Many associated classes scattered across different subject hierarchies could be discovered from the circulation patterns of similar users. The obtained association norms between classes were found to be useful in understanding users' subject preferences for a given class. Classification schemes can, therefore, be made more adaptable to changes of users and the uses of different library collections. There are implications for applications in information organization and retrieval as well. For example, catalogers could refer to the ranked associated classes when they perform multi-classification, and users could also browse the associated classes for related subjects in an enhanced OPAC system. In future research, more empirical studies will be needed to validate the findings, and methods for obtaining user-oriented associations can still be improved.[Article content in Chinese

    Full Text Available Introduction. Development of the polymerase chain reaction and deoxyribonucleic acid sequencing techniques has enabled precise identification, classification and taxonomy of viruses. Comparative sequence analysis. Comparative sequence analysis methods can be used in medical virology for many practical purposes. They may be classified into three broad categories: I - reconstruction of genealogical relationships between individual viral isolates for detection and monitoring of sources, reservoirs and modes of viral transmission; II - virus genotyping, that is determination of relationships between genetic types of viruses and their phenotypic properties, which has important implications for immuno-prophylaxis, therapy and prognosis of viral diseases; and III -investigation of functional properties of defined viral sequences, of special importance for explanation of viral pathogenesis and design of antiviral drugs. Future prospects. The combination of DNA sequencing with polymerase chain reaction following reverse transcription with the use of random primers offers a universal means for diagnosis of viral infections. .

  4. Comparative analysis of radionuclide inventory in sediment 1995

    International Nuclear Information System (INIS)

    In order to test the reliability of methods used in environmental monitoring for radioactive substances, the Bundesanstalt fuer Gewaesserkunde in 1995 again carried out a comparative analysis ''Radionuclides in sediment'' with correspondingly labelled or conditioned samples. The primary aim of this project - independently of the method used in each instance and the measuring conditions observed - was to establish the extent to which the measuring results of the individual participants deviate from specified supposed values or likeliest contents, and also to valuate these deviations by means of illustrative quality parameters. In so far the aim of this comparative analysis differs from that of a so-called inter-laboratory experiment, where the primary objective is to obtain characteristic data for an analytical method (orig./SR)

  5. Reactor neutron activation analysis by single comparator method: Ko measurements

    International Nuclear Information System (INIS)

    Neutron activation analysis using single comparator has been adapted for multi element analysis in different matrices. Gold was used as comparator. High resolution gamma ray spectrometry was used for measuring radioactivity. Ko factors for fifteen isotopes were measured using this method. Ko values for 111 radioisotopes for the elements from fluorine to uranium were also calculated using latest nuclear data. Good agreement between the experimental and calculated Ko values was obtained. Ratio of the sub-cadmium to epi-cadmium neutron flux which is an important input parameter was measured in different irradiation positions of Apsara reactor. Using this method, macro and micro concentrations of analytes in a geological standard (USGS-W-1) and a few gem samples were determined. (author). 28 refs., 5 tabs., 1 appendix

    The results of the focus group discussions and participatory observations (Abdollahyan and Sheykhansari, 2012 indicate that working within Facebook environment leads to the generation of new vocabulary (lingo which is then introduced to new generations of Facebook users. Also, the information turnover and its extent among Facebook users is so much, so that every time that users login in their account they have to face new information about various events. In contrast, those who are not Facebook users, would use other tools of mass media to update their information, based on personal interests. This comparison drags our attention to a very critical phenomenon, i.e., the rate of information exchanged among Facebook users about various socio-political events have grown drastically. The friendship circle of Facebook users becomes expanded because it includes all people that such a user might know during his/her course of life. Whereas the friendship circle of a non-Facebook-user is limited to those with whom the individual is acquainted with in his/her real life and can have a face to face interaction. The level of trust among Facebook users for promoting friendship is high and they accept friendship invitations very easily. They do not have to go through a lot of evaluations to choose their virtual friends. The non-Facebook-users, on the other hand, protect their private spheres and are cautious about new friendships, if they are to choose new friends. We also discovered that there is a prominent difference between Facebook users and non-Facebook users in terms of getting intimate or close with a friend. Nevertheless, taking maintaining family relations as criteria, we noticed that almost all family members in the same age had a tendency to get connected through Facebook. It is possible therefore that if a familial connection is somehow cut off in the real life, reconnection happens through same-age groups in Facebook. Generally, Facebook functions in two ways for families, i.e., on the one had it preserves connections at a minimal level and on the other hand, it is a means of monitoring one another without having any real connections. The results also indicate that using Facebook can improve psychological health of a person. Those Facebook users who have a low level of self-esteem, use Facebook as a means of strengthening their social relations. We also discovered that Facebook users have a higher level of satisfaction from their friendship relationships and like to be with their Facebook friends, even more than the company of friends in actual space.

  10. Comparative analysis of the mitochondrial genomes in gastropods

    International Nuclear Information System (INIS)

    In this work we presented a comparative analysis of the mitochondrial genomes in gastropods. Nucleotide and amino acids composition was calculated and a comparative visual analysis of the start and termination codons was performed. The organization of the genome was compared calculating the number of intergenic sequences, the location of the genes and the number of reorganized genes (breakpoints) in comparison with the sequence that is presumed to be ancestral for the group. In order to calculate variations in the rates of molecular evolution within the group, the relative rate test was performed. In spite of the differences in the size of the genomes, the amino acids number is conserved. The nucleotide and amino acid composition is similar between Vetigastropoda, Ceanogastropoda and Neritimorpha in comparison to Heterobranchia and Patellogastropoda. The mitochondrial genomes of the group are very compact with few intergenic sequences, the only exception is the genome of Patellogastropoda with 26,828 bp. Start codons of the Heterobranchia and Patellogastropoda are very variable and there is also an increase in genome rearrangements for these two groups. Generally, the hypothesis of constant rates of molecular evolution between the groups is rejected, except when the genomes of Caenogastropoda and Vetigastropoda are compared.

  11. A comparative analysis of the Global Land Cover 2000 and MODIS land cover data sets

    Accurate and up-to-date global land cover data sets are necessary for various global change research studies including climate change, biodiversity conservation, ecosystem assessment, and environmental modeling. In recent years, substantial advancement has been achieved in generating such data products. Yet, we are far from producing geospatially consistent high-quality data at an operational level. We compared the recently available Global Land Cover 2000 (GLC-2000) and MODerate resolution Imaging Spectrometer (MODIS) global land cover data to evaluate the similarities and differences in methodologies and results, and to identify areas of spatial agreement and disagreement. These two global land cover data sets were prepared using different data sources, classification systems, and methodologies, but using the same spatial resolution (i.e., 1 km) satellite data. Our analysis shows a general agreement at the class aggregate level except for savannas/shrublands, and wetlands. The disagreement, however, increases when comparing detailed land cover classes. Similarly, percent agreement between the two data sets was found to be highly variable among biomes. The identified areas of spatial agreement and disagreement will be useful for both data producers and users. Data producers may use the areas of spatial agreement for training area selection and pay special attention to areas of disagreement for further improvement in future land cover characterization and mapping. Users can conveniently use the findings in the areas of agreement, whereas users might need to verify the informaiton in the areas of disagreement with the help of secondary information. Learning from past experience and building on the existing infrastructure (e.g., regional networks), further research is necessary to (1) reduce ambiguity in land cover definitions, (2) increase availability of improved spatial, spectral, radiometric, and geometric resolution satellite data, and (3) develop advanced classification algorithms. ?? 2004 Elsevier Inc.

    Full Text Available Electronic Learning has been one of the foremost trends in education so far. Such importance draws the attention to an important shift in the educational paradigm. Due to the complexity of the evolving paradigm, the prospective dynamics of learning require an evolution of knowledge delivery and evaluation. This research work tries to put in hand a futuristic design of an autonomous and intelligent e-Learning system. In which machine learning and user activity analysis play the role of an automatic evaluator for the knowledge level. It is important to assess the knowledge level in order to adapt content presentation and to have more realistic evaluation of online learners. Several classification algorithms are applied to predict the knowledge level of the learners and the corresponding results are reported. Furthermore, this research proposes a modern design of a dynamic learning environment that goes along the most recent trends in e-Learning. The experimental results illustrate an overall performance superiority of a support vector machine model in evaluating the knowledge levels; having 98.6%of correctly classified instances with 0.0069 mean absolute error.

  14. SHEAT: a computer code for probabilistic seismic hazard analysis, user's manual

    International Nuclear Information System (INIS)

    The SHEAT code developed at Japan Atomic Energy Research Institute is for probabilistic seismic hazard analysis which is one of the tasks needed for seismic Probabilistic Safety Assessment (PSA) of a nuclear power plant. Seismic hazard is defined as an annual exceedance frequency of occurrence of earthquake ground motions at various levels of intensity at a given site. With the SHEAT code, seismic hazard is calculated by the following two steps: (1) Modeling of earthquake generation around a site. Future earthquake generation (locations, magnitudes and frequencies of postulated earthquakes) is modelled based on the historical earthquake records, active fault data and expert judgement. (2) Calculation of probabilistic seismic hazard at the site. An earthquake ground motion is calculated for each postulated earthquake using an attenuation model taking into account its standard deviation. Then the seismic hazard at the site is calculated by summing the frequencies of ground motions by all the earthquakes. This document is the user's manual of the SHEAT code. It includes: (1) Outlines of the code, which include overall concept, logical process, code structure, data file used and special characteristics of the code, (2) Functions of subprograms and analytical models in them, (3) Guidance of input and output data, and (4) Sample run results. The code has widely been used at JAERI to analyze seismic hazard at various nuclear power plant sites in japan. (author)

  15. GATA: a graphic alignment tool for comparative sequence analysis

    Directory of Open Access Journals (Sweden)

    Nix David A

    2005-01-01

    Full Text Available Abstract Background Several problems exist with current methods used to align DNA sequences for comparative sequence analysis. Most dynamic programming algorithms assume that conserved sequence elements are collinear. This assumption appears valid when comparing orthologous protein coding sequences. Functional constraints on proteins provide strong selective pressure against sequence inversions, and minimize sequence duplications and feature shuffling. For non-coding sequences this collinearity assumption is often invalid. For example, enhancers contain clusters of transcription factor binding sites that change in number, orientation, and spacing during evolution yet the enhancer retains its activity. Dot plot analysis is often used to estimate non-coding sequence relatedness. Yet dot plots do not actually align sequences and thus cannot account well for base insertions or deletions. Moreover, they lack an adequate statistical framework for comparing sequence relatedness and are limited to pairwise comparisons. Lastly, dot plots and dynamic programming text outputs fail to provide an intuitive means for visualizing DNA alignments. Results To address some of these issues, we created a stand alone, platform independent, graphic alignment tool for comparative sequence analysis (GATA http://gata.sourceforge.net/. GATA uses the NCBI-BLASTN program and extensive post-processing to identify all small sub-alignments above a low cut-off score. These are graphed as two shaded boxes, one for each sequence, connected by a line using the coordinate system of their parent sequence. Shading and colour are used to indicate score and orientation. A variety of options exist for querying, modifying and retrieving conserved sequence elements. Extensive gene annotation can be added to both sequences using a standardized General Feature Format (GFF file. Conclusions GATA uses the NCBI-BLASTN program in conjunction with post-processing to exhaustively align two DNA sequences. It provides researchers with a fine-grained alignment and visualization tool aptly suited for non-coding, 0–200 kb, pairwise, sequence analysis. It functions independent of sequence feature ordering or orientation, and readily visualizes both large and small sequence inversions, duplications, and segment shuffling. Since the alignment is visual and does not contain gaps, gene annotation can be added to both sequences to create a thoroughly descriptive picture of DNA conservation that is well suited for comparative sequence analysis.

  16. User centric approach to itemset utility mining in Market Basket Analysis

    2011-01-01

    Full Text Available Business intelligence is information about a company's past performance that is used to help predict the company's future performance. It can reveal emerging trends from which the company might profit [31]. Data mining allows users to sift through the enormous amount of information available in data warehouses; it is from this sifting process that business intelligence gems may be found [31]. Within the area of data mining, the problem of deriving associations from data has received a great deal of attention. This problem is referred as “market-basket problem”. Association Rule Mining (ARM, a well-studied technique in the data mining field, identifies frequent itemsets from databases and generates association rules by assuming that all items have the same significance andfrequency of occurrence in a record. However, items are actually different in many aspects in a number of real applications such as retail marketing, nutritional pattern mining, etc [26]. Rare items are less frequent items [32]. For many real world applications, however, utility of rare itemsets based on cost, profit or revenue is of importance. For extracting rare itemsets, the equal frequency based approaches like Apriori approach suffer from “rare item problem dilemma”. Utility mining aims at identifying rare itemsets with high utility. The main objective of Utility Mining is to identify the itemsets with highest utilities, by considering profit, quantity, costor other user preferences [40]. Also valuable patterns cannot be discovered by traditional non-temporal data mining approaches that treat all the data as one large segment, with no attention paid to utilizing the time information of transactions. Now, as increasingly complex real-world problems are addressed, temporal rare itemset utility problem, are taking center stage. In many real-life applications, high-utility itemsets consist of rare items. Rare itemsets provide useful information in different decision-making domains such as business transactions, medical, security, fraudulenttransactions, and retail communities. For example, in a supermarket, customers purchase microwave ovens or frying pans rarely as compared to bread, washing powder, soap. But the former transactions yield more profit for the supermarket. A retail business may be interested in identifying its most valuable customers i.e. who contribute a major fraction of overall company profit [40]. In this paper, these problems of analyzing market-basket data are considered and important contributions are presented. It is assumed that the utilities of itemsets may differ and determine the high utility itemsets based onboth internal (transaction and external utilities.

    1999-01-01

    The primary objective of this study was the development of a Computational Fluid Dynamics (CFD) based turbomachinery airfoil analysis and design system, controlled by a Graphical User Interface (GUI). The computer codes resulting from this effort are referred to as TADS (Turbomachinery Analysis and Design System). This document is intended to serve as a User's Manual for the computer programs which comprise the TADS system, developed under Task 18 of NASA Contract NAS3-27350, ADPAC System Coupling to Blade Analysis & Design System GUI and Task 10 of NASA Contract NAS3-27394, ADPAC System Coupling to Blade Analysis & Design System GUI, Phase II-Loss, Design and, Multi-stage Analysis. TADS couples a throughflow solver (ADPAC) with a quasi-3D blade-to-blade solver (RVCQ3D) in an interactive package. Throughflow analysis and design capability was developed in ADPAC through the addition of blade force and blockage terms to the governing equations. A GUI was developed to simplify user input and automate the many tasks required to perform turbomachinery analysis and design. The coupling of the various programs was done in such a way that alternative solvers or grid generators could be easily incorporated into the TADS framework. Results of aerodynamic calculations using the TADS system are presented for a highly loaded fan, a compressor stator, a low speed turbine blade and a transonic turbine vane.

    Gazak, J Zachary; Tonry, John; Eastman, Jason; Mann, Andrew W; Agol, Eric

    2011-01-01

    We present an IDL graphical user interface-driven software package designed for the analysis of extrasolar planet transit light curves. The Transit Analysis Package (TAP) software uses Markov Chain Monte Carlo (MCMC) techniques to fit light curves using the analytic model of Mandel and Agol (2002). The package incorporates a wavelet based likelihood function developed by Carter and Winn (2009) which allows the MCMC to assess parameter uncertainties more robustly than classic chi-squared methods by parameterizing uncorrelated "white" and correlated "red" noise. The software is able to simultaneously analyze multiple transits observed in different conditions (instrument, filter, weather, etc). The graphical interface allows for the simple execution and interpretation of Bayesian MCMC analysis tailored to a user's specific data set and has been thoroughly tested on ground-based and Kepler photometry. AutoKep provides a similar GUI for the preparation of Kepler MAST archive data for analysis by TAP or any other a...

  2. Canine Mammary Carcinomas: A Comparative Analysis of Altered Gene Expression

    Full Text Available Breast cancer represents the second most frequent neoplasm in humans and sexually intact female dogs after lung and skin cancers, respectively. Many similar features in human and dog cancers including, spontaneous development, clinical presentation, tumor heterogeneity, disease progression and response to conventional therapies have supported development of this comparative model as an alternative to mice. The highly conserved similarities between canine and human genomes are also key to this comparative analysis, especially when compared to the murine genome. Studies with canine mammary tumor (CMT models have shown a strong genetic correlation with their human counterparts, particularly in terms of altered expression profiles of cell cycle regulatory genes, tumor suppressor and oncogenes and also a large group of non-coding RNAs or microRNAs (miRNAs. Because CMTs are considered predictive intermediate models for human breast cancer, similarities in genetic alterations and cancer predisposition between humans and dogs have raised further interest. Many cancer-associated genetic defects critical to mammary tumor development and oncogenic determinants of metastasis have been reported and appear to be similar in both species. Comparative analysis of deregulated gene sets or cancer signaling pathways has shown that a significant proportion of orthologous genes are comparably up- or down-regulated in both human and dog breast tumors. Particularly, a group of cell cycle regulators called cyclin-dependent kinase inhibitors (CKIs acting as potent tumor suppressors are frequently defective in CMTs. Interestingly, comparative analysis of coding sequences has also shown that these genes are highly conserved in mammals in terms of their evolutionary divergence from a common ancestor. Moreover, co-deletion and/or homozygous loss of the INK4A/ARF/INK4B (CDKN2A/B locus, encoding three members of the CKI tumor suppressor gene families (p16/INK4A, p14ARF and p15/INK4B, in many human and dog cancers including mammary carcinomas, suggested their important conserved genetic order and localization in orthologous chromosomal regions. miRNAs, as powerful post-transcriptional regulators of most of the cancer-associated genes, have not been well evaluated to date in animal cancer models. Comprehensive expression profiles of miRNAs in CMTs have revealed their altered regulation showing a strong correlation with those found in human breast cancers. These genetic correlations between human and dog mammary cancers will greatly advance our understanding of regulatory mechanisms involving many critical cancer-associated genes that promote neoplasia and contribute to the promising development of future therapeutics.

    2014-01-01

    The somatostatin protein plays a crucial role in the regulation of multiple biological functions, such as growth, fat deposition, and nutrient absorption in vertebrates. Polymorphisms in the somatostatin gene have been associated with growth traits in livestock species, including cattle and goat. In this study, we conducted complete molecular characterization of the somatostatin gene in Bubalus bubalis (Murrah breed) by sequencing a Murrah BAC clone spanning 72,489 base pairs (bp) in length. The buffalo somatostatin gene contains 1481 bp organized into a 5'-untranslated region (135 bp), exon 1 (139 bp), intron 1 (839 bp), exon 2 (212 bp), and 3'UTR (156 bp). Comparative analysis between the buffalo somatostatin DNA coding sequence and the amino acid sequence with other bovids (cattle, goat, and sheep), horse, pig, human, rodents (mouse and rat), and chicken. Identity varied from 83-99% on the DNA sequence level and 88-100% on the protein level. In addition, a comparison of gene sequences between Murrah and Mediterranean breeds revealed 6 potential single-nucleotide polymorphisms (1 in exon 1 and 5 in intron 1), which were validated in different buffalo populations. This comparative analysis provides basic information for future studies of different buffalo herds using the position candidate gene approach, quantitative trait loci analysis, and polymorphisms associated with growth traits.

    The biofouling of the surfaces immersed in water is one of the most important problems which must be solved in the naval field. This phenomenon is amplified during the harbor operations, when the ships are stationary and there is a high density of microorganisms in the neritic area, developing the biofouling. For this reason, in order to prevent or delay the deposition of the first layers of biofouling, different methods have been used [1]. This paper presents the comparative analysis of microorganisms’ behavior obtained by using GlidArc technology for the treatment of the naval metallic surfaces [2, 3]. The main parameters identified for data processing were: the number of microorganisms shared from the point of view of sensibility to the used technology found on the metallic surfaces, the type of the naval paint and the treatment methods. For analysis it was used the epifluorescence microscopy method with. The comparative analysis follows the data processing which has the same input characteristics. Finally it was observed the microorganism's lifetime after the surface treatment.

    Given the growth in methamphetamine use in China during the 21st century, we assessed perceived psychosocial barriers to drug treatment among this population. Using a sample of 303 methamphetamine users recruited via Respondent Driven Sampling, we use Latent Class Analysis (LCA) to identify possible distinct latent groups among Chinese methamphetamine users on the basis of their perceptions of psychosocial barriers to drug treatment. After covariates were included to predict latent class membership, the 3-step modeling approach was applied. Our findings indicate that the Chinese methamphetamine using population was heterogeneous on perceptions of drug treatment barriers; four distinct latent classes (subpopulations) were identified - Unsupported Deniers, Deniers, Privacy Anxious, and Low Barriers - and individual characteristics shaped the probability of class membership. Efforts to link Chinese methamphetamine users to treatment may require a multi-faceted approach that attends to differing perceptions about impediments to drug treatment. PMID:26738640

  8. Performance analysis of spectrum sensing with multiple status changes in primary user traffic

    KAUST Repository

    Tang, Liang

    2012-06-01

    In this letter, the impact of primary user traffic with multiple status changes on the spectrum sensing performance is analyzed. Closed-form expressions for the probabilities of false alarm and detection are derived. Numerical results show that the multiple status changes of the primary user cause considerable degradation in the sensing performance. This degradation depends on the number of changes, the primary user traffic model, the primary user traffic intensity and the signal-to-noise ratio of the received signal. Numerical results also show that the amount of degradation decreases when the number of changes increases, and converges to a minimum sensing performance due to the limited sensing period and primary holding time. © 2012 IEEE.

    2013-12-01

    Full Text Available A comparative study of Thailand and Japan investigated how electronic commerce (EC in developing countries can be used to attract customers from developed countries. Thai and Japanese participants were shown language-appropriate versions of a hotel booking website in Thailand. Perceptions of and trust in the website were assessed, as was the willingness to book a room in the hotel using the website. The Thai participants tended to evaluate the quality of the website more highly and to trust it more than did the Japanese participants. Furthermore, the Thai participants tended to think that the hotel was more responsible for their hotel reservations than was the EC service, and that the content of the website was developed by the hotel rather than by the EC service. Thai participants were more likely to express willingness to reserve a room if they thought that the hotel had developed the website content, whereas the Japanese participants’ willingness to book a room were greater when they thought that the EC service had developed the content. Based on these results, customization strategies for EC in developing countries to attract customers from developed countries are discussed.

    Rasmussen, Rasmus; Kushniruk, Andre

    2013-01-01

    As hospital departments continue to introduce electronic whiteboards in real clinical settings a range of human factor issues have emerged and it has become clear that there is a need for improved methods for designing and testing these systems. In this study, we employed a longitudinal and naturalistic method in the usability evaluation of an electronic whiteboard system. The goal of the evaluation was to explore the extent to which usability issues experienced by users change as they gain more experience with the system. In addition, the paper explores the use of a new approach to collection and analysis of continuous digital video recordings of naturalistic "live" user interactions. The method developed and employed in the study included recording the users' interactions with system during actual use using screen-capturing software and analyzing these recordings for usability issues. In this paper we describe and discuss both the method and the results of the evaluation. We found that the electronic whiteboard system contains system-related usability issues that did not change over time as the clinicians collectively gained more experience with the system. Furthermore, we also found user-related issues that seemed to change as the users gained more experience and we discuss the underlying reasons for these changes. We also found that the method used in the study has certain advantages over traditional usability evaluation methods, including the ability to collect analyze live user data over time. However, challenges and drawbacks to using the method (including the time taken for analysis and logistical issues in doing live recordings) should be considered before utilizing a similar approach. In conclusion we summarize our findings and call for an increased focus on longitudinal and naturalistic evaluations of health information systems and encourage others to apply and refine the method utilized in this study.

    2014-01-01

    Bacteriophages attacking Leuconostoc species may significantly influence the quality of the final product. There is however limited knowledge of this group of phages in the literature. We have determined the complete genome sequences of nine Leuconostoc bacteriophages virulent to either Leuconostoc mesenteroides or Leuconostoc pseudomesenteroides strains. The phages have dsDNA genomes with sizes ranging from 25.7 to 28.4kb. Comparative genomics analysis helped classify the 9 phages into two classes, which correlates with the host species. High percentage of similarity within the classes on both nucleotide and protein levels was observed. Genome comparison also revealed very high conservation of the overall genomic organization between the classes. The genes were organized in functional modules responsible for replication, packaging, head and tail morphogenesis, cell lysis and regulation and modification, respectively. No lysogeny modules were detected. To our knowledge this report provides the first comparative genomic work done on Leuconostoc dairy phages.

  1. Stigma, sex work, and substance use: a comparative analysis.

    Science.gov (United States)

    Benoit, Cecilia; McCarthy, Bill; Jansson, Mikael

    2015-03-01

    Stigma is a widely used concept in social science research and an extensive literature claims that stigmatisation contributes to numerous negative health outcomes. However, few studies compare groups that vary in the extent to which they are stigmatised and even fewer studies examine stigma's independent and mediating effects. This article addresses these gaps in a comparative study of perceived stigma and drug use among three low-income feminised service occupations: sex work, food and alcoholic beverage serving, and barbering and hairstyling. An analysis of longitudinal data shows positive associations between sex work, perceived stigma, and socially less acceptable drug use (for example, heroin and cocaine), and that stigma mediates part of the link between sex work and the use of these drugs. Our overall findings suggest that perceived stigma is pronounced among those who work in the sex industry and negatively affects health independently of sex work involvement. PMID:25688450

    2015-09-01

    We consider multiple-antenna signal detection of primary user transmission signals by a secondary user receiver in cognitive radio networks. The optimal detector is analyzed for the scenario where the number of primary user signals is no less than the number of receive antennas at the secondary user. We first derive exact expressions for the moments of the generalized likelihood ratio test (GLRT) statistic, yielding approximations for the false alarm and detection probabilities. We then show that the normalized GLRT statistic converges in distribution to a Gaussian random variable when the number of antennas and observations grow large at the same rate. Further, using results from large random matrix theory, we derive expressions to compute the detection probability without explicit knowledge of the channel, and then particularize these expressions for two scenarios of practical interest: 1) a single primary user sending spatially multiplexed signals, and 2) multiple spatially distributed primary users. Our analytical results are finally used to obtain simple design rules for the signal detection threshold.

    Full Text Available In this article the negotiations and peace processes in the Third World are analized from a comparative viewpoint in order to focus in on the case of Centroamerica. Reference is made to the special features and common elements of those peace processes in otherregions of the Third World and they are compared to those which have taken place in Centroamerica. It is a retrospective and comparative analysis. For this reason, the author has decided to carry out a brief typology of those conflicts offered by Centroamerica: inNicaragua, El Salvador and Guatemala. Later, the author goes on to analyse the most relevant peace and negotiation processes involving the Third World including one or two from Latin America: the cases of Panama, Afghanistan, Iran-Iraq, Colombia, southern Africa (South Africa, Namibia and Angola and Cambodia. Later, the author goes overthe peace process periods in Centroamerica and the temporary contradictions which are presented by internal conflict, regional conflict and geopolitical conflict. Finally, a comparative methodological exercise is carried out which allows to focus on modes of implementation of the peace processes.

    2014-01-01

    This study presents a comparative analysis of F1 and F2 vowel frequencies from Pijal Media Lengua (PML) and Imbabura Quichua. Mixed-effects models are used to test Spanish-derived high and low vowels against their Quichua-derived counterparts for statistical significance. Spanish-derived and Quichua-derived high vowels are also tested against Spanish-derived mid vowels. This analysis suggests that PML may be manipulating as many as eight vowels where Spanishderived high and low vowels coexist as near-mergers with their Quichua-derived counterparts, while high and mid vowels coexist with partial overlap. Quichua, traditionally viewed as a three-vowel system, shows similar results and may be manipulating as many as six vowels. PMID:25721292

    The finished sequence of human chromosome 10 comprises a total of 131,666,441 base pairs. It represents 99.4% of the euchromatic DNA and includes one megabase of heterochromatic sequence within the pericentromeric region of the short and long arm of the chromosome. Sequence annotation revealed 1,357 genes, of which 816 are protein coding, and 430 are pseudogenes. We observed widespread occurrence of overlapping coding genes (either strand) and identified 67 antisense transcripts. Our analysis suggests that both inter- and intrachromosomal segmental duplications have impacted on the gene count on chromosome 10. Multispecies comparative analysis indicated that we can readily annotate the protein-coding genes with current resources. We estimate that over 95% of all coding exons were identified in this study. Assessment of single base changes between the human chromosome 10 and chimpanzee sequence revealed nonsense mutations in only 21 coding genes with respect to the human sequence. PMID:15164054

    The finished sequence of human chromosome 20 comprises 59,187,298 base pairs (bp) and represents 99.4% of the euchromatic DNA. A single contig of 26 megabases (Mb) spans the entire short arm, and five contigs separated by gaps totalling 320 kb span the long arm of this metacentric chromosome. An additional 234,339 bp of sequence has been determined within the pericentromeric region of the long arm. We annotated 727 genes and 168 pseudogenes in the sequence. About 64% of these genes have a 5' and a 3' untranslated region and a complete open reading frame. Comparative analysis of the sequence of chromosome 20 to whole-genome shotgun-sequence data of two other vertebrates, the mouse Mus musculus and the puffer fish Tetraodon nigroviridis, provides an independent measure of the efficiency of gene annotation, and indicates that this analysis may account for more than 95% of all coding exons and almost all genes.

    The nonverbal communications of schizophrenics and normals in dyadic interactions were analyzed and compared. Twelve purposively selected women were videotaped in normal-normal, normal-schizophrenic, and schizophrenic-schizophrenic communication acts for 30 minutes. Using a PLATO IV computer program and a modified Kendon Kinesic Notation System, a priori sets of nonverbal behaviors were recorded at 1-second intervals. Frequency and duration scores for the sets of nonverbal behaviors with corresponding communication meanings were totaled. A nested analysis of variance showed that the three groups differed significantly (p less than .05) in engagement and defensiveness and that the normal interactors were the least imitative of the three groups. An analysis and description of the patterns of nonverbal communication also revealed differences, lending support to the theory of dysjunctive schizophrenic communication. PMID:6901546

    Full Text Available There is a need to properly define soil compaction as one of the complex soil characteristics relevant to agriculture since it greatly influences plant growth and energy consumption. The level of soil compaction may be described by many, well known, parameters, which also can be comparatively analysed according to its sensitivity and ability to describe soil reaction to the applied load. This paper presents a specific analysis of soil compaction measurement methods based on laboratory testing. The sensitivity of usual compaction parameters such as tire sinkage, cone index and soil bulk density, as well as needle penetration were taken into consideration. The paper also includes the critical analysis of different measurement techniques and its possibility to be a source of valuable agricultural information.

  14. Comparative Study of Reliability Analysis Methods for Discrete Bimodal Information

    International Nuclear Information System (INIS)

    The distribution of a response usually depends on the distribution of a variable. When the distribution of a variable has two different modes, the response also follows a distribution with two different modes. In most reliability analysis methods, the number of modes is irrelevant, but not the type of distribution. However, in actual problems, because information is often provided with two or more modes, it is important to estimate the distributions with two or more modes. Recently, some reliability analysis methods have been suggested for bimodal distributions. In this paper, we review some methods such as the Akaike information criterion (Aic) and maximum entropy principle (Me) and compare them with the Monte Carlo simulation (MRCS) using mathematical examples with two different modes

    The completion of the Arabidopsis thaliana genome sequence allows a comparative analysis of transcriptional regulators across the three eukaryotic kingdoms. Arabidopsis dedicates over 5% of its genome to code for more than 1500 transcription factors, about 45% of which are from families specific to plants. Arabidopsis transcription factors that belong to families common to all eukaryotes do not share significant similarity with those of the other kingdoms beyond the conserved DNA binding domains, many of which have been arranged in combinations specific to each lineage. The genome-wide comparison reveals the evolutionary generation of diversity in the regulation of transcription. PMID:11118137

  6. CIVIL LIABILITY FOR NUCLEAR DAMAGE: COMPARATIVE ANALYSIS OF INTERNATIONAL TREATIES

    Directory of Open Access Journals (Sweden)

    Laura Rimšait?

    2013-06-01

    Full Text Available It was widely accepted that nuclear damage might be extensive and spread to other countries. International civil liability for nuclear damage is embodied by two major instruments: International Atomic Energy Agency (IAEA 1963 Vienna Convention on Civil liability for Nuclear Damage and Paris Convention of 1960 on third party liability (OECD with its amending protocols. Major problem arises because of lack of coherence and for this reason supplementary conventions and protocols has been adopted but sufficient results has not been achieved. International treaties on civil liability for nuclear damage are mostly based upon principles of operator’s exclusive, channeling, strict liability for nuclear damage, mandatory financial coverage, compensation without discrimination. These principles set ground for the appropriate compensation standard thus minimizing the difficulty level of complicated legal cross-actions and identifies certain subjects in individual cases who are liable also allows a concentration of the insurance capacity. Although Conventions sets similar principles, Europe remains in two different liability regimes which cover differences of liability amounts, scope of application, rules of jurisdiction conflicts. Problem of legal coherence at European Union level also arises because Member States are either parties to the Paris Convention or Vienna Convention at different speeds. This research paper provides an in-depth analysis of international legal framework development and impetus to create trans-boundary compensation mechanisms thus to foster development of European Union nuclear energy market and to provide higher protection for victims inside and outside the country where the incident has occurred. Purpose – provide comparative analysis of international treaties which regulate civil liability for nuclear damage in the context of European Union nuclear energy market development. Design/methodology - paper is based on document analysis, systemic, comparative analysis method by comparing different conventions and its implications. Findings – two liability regimes set different liability amount for the operator and some additional implications to the State and with its amendments provides additional compensation options from all contracting parties collected funds. However the problem rises for the operator to provide insurance whereas Vienna convention only sets minimum liability amount and it is up to state to decide on liability limits or even to provide unlimited liability for the operator. In this case operator faces difficulties to find appropriate insurance as it has to be guaranteed for certain amount. Another situation when a State provides very high maximum amount of the operator’s liability therefore state aid problem arises because there is a need for state guarantee or when there are several operators and not all of them need this amount of insurance because they are being decommissioned. Research limitations – to analyze liability regimes in the light of cohesion and harmonization of regimes also the obligation of the nuclear installation operator to provide insurance when maximum amounts or blank indemnity are set by national law. Practical implication – This comparative analysis provides a background on further discussions concerning the nuclear operator’s liability and insurance limits issues and cohesion between two regimes by providing a harmonized model throughout European Union. Originality – Only a few authors have analyzed some aspects of nuclear liability there is still a lack of academic insights into nuclear liability regimes and insurance issues in the light of competition law. This work provides insights into nuclear liability issues and will certainly be valuable in practice when developing nuclear projects. Keywords: civil liability for nuclear damage, Vienna Convention, Paris Convention, operator of nuclear installation, strict liability, comparative analysis. Research type: research paper

  7. HYDRA-II: A hydrothermal analysis computer code: Volume 2, User's manual

    International Nuclear Information System (INIS)

    HYDRA-II is a hydrothermal computer code capable of three-dimensional analysis of coupled conduction, convection, and thermal radiation problems. This code is especially appropriate for simulating the steady-state performance of spent fuel storage systems. The code has been evaluated for this application for the US Department of Energy's Commercial Spent Fuel Management Program. HYDRA-II provides a finite-difference solution in cartesian coordinates to the equations governing the conservation of mass, momentum, and energy. A cylindrical coordinate system may also be used to enclose the cartesian coordinate system. This exterior coordinate system is useful for modeling cylindrical cask bodies. The difference equations for conservation of momentum incorporate directional porosities and permeabilities that are available to model solid structures whose dimensions may be smaller than the computational mesh. The equation for conservation of energy permits modeling of orthotropic physical properties and film resistances. Several automated methods are available to model radiation transfer within enclosures and from fuel rod to fuel rod. The documentation of HYDRA-II is presented in three separate volumes. Volume 1 - Equations and Numerics describes the basic differential equations, illustrates how the difference equations are formulated, and gives the solution procedures employed. This volume, Volume 2 - User's Manual, contains code flow charts, discusses the code structure, provides detailed instructions for preparing an input file, and illustrates the operation of the code by means of a sample problem. The final volume, Volume 3 - Verification/Validation Assessments, provides a comparison between the analytical solution and the numerical simulation for problems with a known solution. 6 refs

    1987-06-01

    A survey of 50 potential solar residential sites for comparison of energy use before and after solar space heating installations produced five homes that met the necessary requirements. Results show that fuel savings ranged from 30.6% to 32.0% of the heating requirements. The solar collectors used air as the transfer fluid; living space varied from 1500 ft/sup 2/ to 2700 ft/sup 2/. An f-chart analysis was performed on the five systems and compared to the actual fuel savings. The f-chart program predicted fuel savings of 10.5% to 17.9%, a significant difference. Another performance program, MONSUN, was subsequently compared to the test results. The MONSUN program uses weather data input collected over the past five years for the micro--climate in Kalamazoo, Michigan. Data compared more favorable with predicted values, ranging from 22.9% to 36.8%. The test results from specific installations, carefully analyzed, represent undisputable evidence to the potential solar user. Theoretical analysis is as good as the assumptions made and lacks credibility. Discrepancies between actual data and theoretical predictions can be found in two principal areas: (1) inaccurate weather data input and (2) differences between the collector efficiency curve established on the test stand (ASHRAE 93-77) and the actual installed efficiency curve. The later discrepancy can be attributed to differences in flow rate between test and field results.

    Full Text Available Ultra wideband (UWB technology has been widely used for wireless communication systems including long and short ranges. Wireless computer network is a short range communication system. The present study provides a detailed analysis and performance evaluation of an Ultra-Wideband wireless computer network in a dynamic environment. This includes multi-users state, various modulation schemes and different channel models. Time-Hopping multiple access technique (TH has been selected to evaluate the network performance in multi-users environment. In addition, three modulation techniques including Pulse Position Modulation (TH-PPM, Binary Phase Shift Keying (TH-BPSK and Quadrature Amplitude Modulation (QAM have been used in this analysis. Two types of channel models for each modulation scheme have been used to simulate dynamic environment. The channel models are CM1 (line-of-sight and/or CM3 (Non-line-of-sight along with AWGN (IEEE 802.15.3a. Simulation results show that performance of the local area wireless computer network is highly dependent on the channel environment, the maximum allowable number of active users and the receiver structure. Therefore, prior information of the channel model as well as maximum number of active users is required to optimize the desired performance of the wireless computer network for a specific receiver model.

    The electricity sector has entered into a phase of both challenges and opportunities. Challenges include workforce retirement, labour shortages, and increased competition from other employers to attract and retain the skilled people required to deliver on the increasing demand for electricity in Canada. The electricity sector in Canada is also moving into a new phase, whereby much of the existing infrastructure is either due for significant upgrades, or complete replacement. The increasing demand for electricity means that increased investment and capital expenditure will need to be put toward building new infrastructure altogether. The opportunities for the electricity industry will lie in its ability to effectively and efficiently react to these challenges. The purpose of this report was to provide employers and stakeholders in the sector with relevant and current trend data to help them make appropriate policy and human resource decisions. The report presented a comparative analysis of a 2004 Canadian Electricity Association employer survey with a 2008 Electricity Sector Council employer survey. The comparative analysis highlighted trends and changes that emerged between the 2004 and 2008 studies. Specific topics that were addressed included overall employment trends; employment diversity in the sector; age of non-support staff; recruitment; and retirements and pension eligibility. Recommendations were also offered. It was concluded that the electricity sector could benefit greatly from implementing on-going recruitment campaigns. refs., tabs., figs.

Preferences of cardiological patients did not differ from preferences of other therapeutic patients. On such criteria as respect for a patient, organization of treatment, rendering the information and physical comfort, satisfaction of our and American patients is quite comparable. Estimation of emotional support is somewhat lower at domestic patients. Involvement of a family to the treatment process is not sufficient both in our clinic, and in the American hospitals. All the patients were mostly unsatisfied in the process of discharge.Conclusion. The estimations of hospital treatment made by patients from clinics of different countries are similar very much. The process of discharge has got the lowest estimation by the surveyed patients. The form of final conversation and its environment require further analysis and correction.

    High operational temperature and pressure in offshore pipelines may lead to unexpected lateral movements, sometimes call lateral buckling, which can have serious consequences for the integrity of the pipeline. The phenomenon of lateral buckling in offshore pipelines needs to be analysed in the design phase using FEM. The analysis should take into account many parameters, including operational temperature and pressure, fluid characteristic, seabed profile, soil parameters, coatings of the pipe, free spans etc. The buckling initiation force is sensitive to small changes of any initial geometric out-of-straightness, thus the modeling of the as-laid state of the pipeline is an important part of the design process. Recently some dedicated finite elements programs have been created making modeling of the offshore environment more convenient that has been the case with the use of general purpose finite element software. The present paper aims to compare thermal buckling analysis of sub sea pipeline performed using different finite elements tools, i.e. general purpose programs (ANSYS, ABAQUS) and dedicated software (SAGE Profile 3D) for a single pipeline resting on an the seabed. The analyses considered the pipeline resting on a flat seabed with a small levels of out-of straightness initiating the lateral buckling. The results show the quite good agreement of results of buckling in elastic range and in the conclusions next comparative analyses with sensitivity cases are recommended. (author)

  15. Comparative risk evaluation for siting a waste analysis laboratory

    International Nuclear Information System (INIS)

    With the US Department of Energy (DOE) focus on environmental restoration and waste management at DOE nuclear waste sites, a significant increase is forecast in the quantity of transuranic (TRU) mixed waste samples that require detailed environmental analysis. Under the direction of the laboratory management branch (EM-532), Westinghouse Hanford Company (Westinghouse Hanford) was commissioned to lead the preparation of an engineering study for site selection of the proposed $300-million DOE Waste Analysis Laboratory (WAL). This assessment provides the DOE with important comparative risk information and data in the site selection process. The six DOE sites under consideration are Hanford Site (HANF), Idaho National Engineering Laboratory (INEL), Los Alamos National Laboratory (LANL), Savannah River Site (SRS), Rocky Flats Plant (RFP), and Oak Ridge National Laboratory (ORNL). The study evaluates relative risk contributions from transportation in terms of severe transportation accidents per year and from external events in terms of respective frequency of exceedance. Detailed calculations and relevant information are documented in report WHC-SD-WM-ES-190. This comparative risk assessment provides an objective engineering study that HANF is the most desirable location for the proposed WAL. The favorable safety data for the HANF can be translated to less risk for identical construction or less cost for achieving the same level of safety

  16. 2004/2008 labour market information comparative analysis report

    International Nuclear Information System (INIS)

    The electricity sector has entered into a phase of both challenges and opportunities. Challenges include workforce retirement, labour shortages, and increased competition from other employers to attract and retain the skilled people required to deliver on the increasing demand for electricity in Canada. The electricity sector in Canada is also moving into a new phase, whereby much of the existing infrastructure is either due for significant upgrades, or complete replacement. The increasing demand for electricity means that increased investment and capital expenditure will need to be put toward building new infrastructure altogether. The opportunities for the electricity industry will lie in its ability to effectively and efficiently react to these challenges. The purpose of this report was to provide employers and stakeholders in the sector with relevant and current trend data to help them make appropriate policy and human resource decisions. The report presented a comparative analysis of a 2004 Canadian Electricity Association employer survey with a 2008 Electricity Sector Council employer survey. The comparative analysis highlighted trends and changes that emerged between the 2004 and 2008 studies. Specific topics that were addressed included overall employment trends; employment diversity in the sector; age of non-support staff; recruitment; and retirements and pension eligibility. Recommendations were also offered. It was concluded that the electricity sector could benefit greatly from implementing on-going recruitment campaigns. refs., tabs., figs

    Full Text Available The Internet revolution has led to significant changes in the way travel agencies interact with customers. Travel websites provide customers diverse services including travel information and products through the Internet. In practical envir onments, Internet users face a variety of travel website service quality (TWSQ that is vague from human beings' subjective judgments, and most criteria have some degree of interdependent or interactive characteristics. In the face of the strong competitio n environment, in order to profit by making customers proceed with transactions on the websites, travel websites should pay more attention to improve their service quality. This study discusses the major factors for travel agency websites quality from the viewpoint of users' perception and explores the use of multiple - attribute decision making (MADM approaches for the evaluation of TWSQ. A comparative analysis of Technique for Order Preference by Similarity to Ideal Solution (TOPSIS and Fuzzy TOPSIS metho ds are illustrated through a practical application from the websites of five travel agencies. Empirical results showed that the proposed methods are viable approaches in solving the evaluation problem of TWSQ.

    There is a vast amount of literature concerning the psychological and physiological effects of ordinary noise on the individual. However, few publications have addressed the analysis of aversive noise. This research analyzes three noises which produce the familiar goose flesh or chilling effect responsivity. These aversive sounds which are made by chalk squeaking on the chalkboard, fingernails on the chalkboard and rubbing styrofoam against a smooth surface are digitally compared to ordinary noise to show how these aversive sounds differ from sounds which are only annoying. This work, which uses Fast Fourier Transform (FFT) analysis is a combination with cross correlation analysis and other innovative methods to produce comparative data on noises, illustrates subtle differences between ordinary and aversive noise which may be useful for future work in acoustics or experimental psychology. The literature review shows disagreement among the numerous works on the effects of ordinary noise on human subjects. One explanation for this difference is the failure to adequately measure and define the dynamic nature of the noise used. The existing literature also establishes that a mixture of tones plus random noise is more annoying (but not aversive) than either the random noise or the tones alone. This investigation shows that one property of aversive noises is the combination of randomness plus tones which vary rapidly with time. This paper utilizes a new digital technique which improves the FFT analyzer resolution by a factor of 25. The resulting +/-2 Hz accuracy facilitated the presentation of frequency variation as a function of time data. Other computer generated graphical data includes the percent harmonic deviation as a function of time, the rate of change of fundamental frequency, and the rate of change in harmonic deviation. From these dynamic data, average values are calculated which show the aversive noise to be consistently greater in mean frequency deviation, average frequency deviation rate, harmonic deviation, and harmonic deviation rate. The cross correlation analysis is used to compare aversive sounds to each other and then the aversive sounds to ordinary noise. The results show average cross correlations among aversive sounds to be 0.91 while the aversive to ordinary noise cross correlation averages 0.57. This work includes 326 computer generated graphical presentations of the dynamic properties of noise.

    Full Text Available Abstract Background Subtypes of the GABAA receptor subunit exhibit diverse temporal and spatial expression patterns. In silico comparative analysis was used to predict transcriptional regulatory features in individual mammalian GABAA receptor subunit genes, and to identify potential transcriptional regulatory components involved in the coordinate regulation of the GABAA receptor gene clusters. Results Previously unreported putative promoters were identified for the β2, γ1, γ3, ε, θ and π subunit genes. Putative core elements and proximal transcriptional factors were identified within these predicted promoters, and within the experimentally determined promoters of other subunit genes. Conserved intergenic regions of sequence in the mammalian GABAA receptor gene cluster comprising the α1, β2, γ2 and α6 subunits were identified as potential long range transcriptional regulatory components involved in the coordinate regulation of these genes. A region of predicted DNase I hypersensitive sites within the cluster may contain transcriptional regulatory features coordinating gene expression. A novel model is proposed for the coordinate control of the gene cluster and parallel expression of the α1 and β2 subunits, based upon the selective action of putative Scaffold/Matrix Attachment Regions (S/MARs. Conclusion The putative regulatory features identified by genomic analysis of GABAA receptor genes were substantiated by cross-species comparative analysis and now require experimental verification. The proposed model for the coordinate regulation of genes in the cluster accounts for the head-to-head orientation and parallel expression of the α1 and β2 subunit genes, and for the disruption of transcription caused by insertion of a neomycin gene in the close vicinity of the α6 gene, which is proximal to a putative critical S/MAR.

    In France, nuclear facilities were designed around very low probabilities of failure. Nevertheless, some extreme climatic events have given rise to exceptional observed surges (outliers) much larger than other observations, and have clearly illustrated the potential to underestimate the extreme water levels calculated with the current statistical methods. The objective of the present work is to conduct a comparative study of three approaches to extreme value analysis, including the annual maxima (AM), the peaks-over-threshold (POT) and the r-largest order statistics (r-LOS). These methods are illustrated in a real analysis case study. All data sets were screened for outliers. Non-parametric tests for randomness, homogeneity and stationarity of time series were used. The shape and scale parameter stability plots, the mean excess residual life plot and the stability of the standard errors of return levels were used to select optimal thresholds and r values for the POT and r-LOS method, respectively. The comparison of methods was based on (i) the uncertainty degrees, (ii) the adequacy criteria and tests, and (iii) the visual inspection. It was found that the r-LOS and POT methods have reduced the uncertainty on the distribution parameters and return level estimates and have systematically shown values of the 100 and 500-year return levels smaller than those estimated with the AM method. Results have also shown that none of the compared methods has allowed a good fit at the right tail of the distribution in the presence of outliers. As a perspective, the use of historical information was proposed in order to increase the representativeness of outliers in data sets. Findings are of practical relevance, not only to nuclear energy operators in France, for applications in storm surge hazard analysis and flood management, but also for the optimal planning and design of facilities to withstand extreme environmental conditions, with an appropriate level of risk.
