  5. Client-server, distributed database strategies in a healthcare record system for a homeless population.

    Chueh, H C; Barnett, G O


    A computer-based healthcare record system being developed for Boston's Healthcare for the Homeless Program (BHCHP) uses client-server and distributed database technologies to enhance the delivery of healthcare to patients of this unusual population. The needs of physicians, nurses and social workers are specifically addressed in the application interface so that an integrated approach to healthcare for this population can be facilitated. These patients and their providers have unique medical information needs that are supported by both database and applications technology. To integrate the information capabilities with the actual practice of providers of care to the homeless, this computer-based record system is designed for remote and portable use over regular phone lines. An initial standalone system is being used at one major BHCHP site of care. This project describes methods for creating a secure, accessible, and scalable computer-based medical record using client-server, distributed database design. PMID:8130445

  6. RA radiological characterization database application

    Radiological characterization of the RA research reactor is one of the main activities in the first two years of the reactor decommissioning project. The raw characterization data from direct measurements or laboratory analyses (defined within the existing sampling and measurement programme) have to be interpreted, organized and summarized in order to prepare the final characterization survey report. This report should be made so that the radiological condition of the entire site is completely and accurately shown with the radiological condition of the components clearly depicted. This paper presents an electronic database application, designed as a serviceable and efficient tool for characterization data storage, review and analysis, as well as for the reports generation. Relational database model was designed and the application is made by using Microsoft Access 2002 (SP1), a 32-bit RDBMS for the desktop and client/server database applications that run under Windows XP.

  8. Database and interface modifications: change management without affecting the clients

    The first Oracle-based Controls Configuration Database (CCDB) was developed in 1986, by which the controls system of CERN's Proton Synchrotron became data-driven. Since then, this mission-critical system has evolved tremendously going through several generational changes in terms of the increasing complexity of the control system, software technologies and data models. Today, the CCDB covers the whole CERN accelerator complex and satisfies a much wider range of functional requirements. Despite its online usage, everyday operations of the machines must not be disrupted. This paper describes our approach with respect to dealing with change while ensuring continuity. The successful strategy that has been put in place is based on the following guidelines: -) Involve end-users right from the start, throughout the design and development process; -) Provide four separate environments for development, unit and functional testing, integration testing (TestBed), production; -) Analyze the impact of a change and try to apply only backward compatible changes; -) Communicate timely, clearly and transparently on scheduled intervention and their impact; and -) Coordinate the upgrades with impacted clients

    The first Oracle®-based Controls Configuration Database (CCDB) was developed in 1986, by which the controls system of CERN’s Proton Synchrotron became data-driven. Since then, this mission-critical system has evolved tremendously going through several generational changes in terms of the increasing complexity of the control system, software technologies and data models. Today, the CCDB covers the whole CERN accelerator complex and satisfies a much wider range of functional requirements. Despite its online usage, everyday operations of the machines must not be disrupted. This paper describes our approach with respect to dealing with change while ensuring continuity. How do we manage the database schema changes? How do we take advantage of the latest web deployed application development frameworks without alienating the users? How do we minimize impact on the dependent systems connected to databases through various APIs? In this paper we will provide our answers to these questions, and to many more.

  17. New NED XML/VOtable Services and Client Interface Applications

    Pevunova, O.; Good, J.; Mazzarella, J.; Berriman, G. B.; Madore, B.


    The NASA/IPAC Extragalactic Database (NED) provides data and cross-identifications for over 7 million extragalactic objects fused from thousands of survey catalogs and journal articles. The data cover all frequencies from radio through gamma rays and include positions, redshifts, photometry and spectral energy distributions (SEDs), sizes, and images. NED services have traditionally supplied data in HTML format for connections from Web browsers, and a custom ASCII data structure for connections by remote computer programs written in the C programming language. We describe new services that provide responses from NED queries in XML documents compliant with the international virtual observatory VOtable protocol. The XML/VOtable services support cone searches, all-sky searches based on object attributes (survey names, cross-IDs, redshifts, flux densities), and requests for detailed object data. Initial services have been inserted into the NVO registry, and others will follow soon. The first client application is a Style Sheet specification for rendering NED VOtable query results in Web browsers that support XML. The second prototype application is a Java applet that allows users to compare multiple SEDs. The new XML/VOtable output mode will also simplify the integration of data from NED into visualization and analysis packages, software agents, and other virtual observatory applications. We show an example SED from NED plotted using VOPlot. The NED website is:

  19. Client-Centric Adaptive Scheduling of Service-Oriented Applications

    Jing Wang; Li-Yong Zhang; Yan-Bo Han


    The paper proposes a client-centric computing model that allows for adaptive execution of service-oriented applications. The model can flexibly dispatch application tasks to the client side and the network side, dynamically adjust an execution scheme to adapt to environmental changes, and thus is expected to achieve better scalability, higher performance and more controllable privacy. Scheduling algorithms and the rescheduling strategies are proposed for the model.Experiments show that with the model the performance of service-oriented application execution can be improved.

  20. ATLAS database application enhancements using Oracle 11g

    Dimitrov, G; The ATLAS collaboration; Blaszczyk, M; Sorokoletov, R


    The ATLAS experiment at LHC relies on databases for detector online data-taking, storage and retrieval of configurations, calibrations and alignments, post data-taking analysis, file management over the grid, job submission and management, condition data replication to remote sites. Oracle Relational Database Management System (RDBMS) has been addressing the ATLAS database requirements to a great extent for many years. Ten database clusters are currently deployed for the needs of the different applications, divided in production, integration and standby databases. The data volume, complexity and demands from the users are increasing steadily with time. Nowadays more than 20 TB of data are stored in the ATLAS production Oracle databases at CERN (not including the index overhead), but the most impressive number is the hosted 260 database schemas (for the most common case each schema is related to a dedicated client application with its own requirements). At the beginning of 2012 all ATLAS databases at CERN have...

  1. Database characterisation of HEP applications

    Piorkowski, Mariusz; Grancher, Eric; Topurov, Anton


    Oracle-based database applications underpin many key aspects of operations for both the LHC accelerator and the LHC experiments. In addition to the overall performance, the predictability of the response is a key requirement to ensure smooth operations and delivering predictability requires understanding the applications from the ground up. Fortunately, database management systems provide several tools to check, measure, analyse and gather useful information. We present our experiences characterising the performance of several typical HEP database applications performance characterisations that were used to deliver improved predictability and scalability as well as for optimising the hardware platform choice as we migrated to new hardware and Oracle 11g.

  4. An Object-Oriented Framework for Client-Server Applications

    When developing high-level accelerator applications it is often necessary to perform extensive calculations to generate a data set that will be used as an input for other applications. Depending on the size and complexity of these computations, regenerating the interim data sets can introduce errors or otherwise negatively impact system perform. If these computational data sets could be generated in advance and be updated continuously from changes in the accelerator, it could substantially reduce the time and effort required in performing subsequent calculations. UNIX server applications are well suited to accommodate this need by providing a centralized repository for data or computational power. Because of the inherent difficulty in writing a robust server application, the development of the network communications software is often more burdensome than the computational engine. To simplify the task of building a client/server application, we have developed an object-oriented server shell which hides the complexity of the network software development from the programmer. This document will discuss how to implement a complete client/server application using this C++ class library with a minimal understanding of network communications mechanisms

  5. Database tomography for commercial application

    Kostoff, Ronald N.; Eberhart, Henry J.


    Database tomography is a method for extracting themes and their relationships from text. The algorithms, employed begin with word frequency and word proximity analysis and build upon these results. When the word 'database' is used, think of medical or police records, patents, journals, or papers, etc. (any text information that can be computer stored). Database tomography features a full text, user interactive technique enabling the user to identify areas of interest, establish relationships, and map trends for a deeper understanding of an area of interest. Database tomography concepts and applications have been reported in journals and presented at conferences. One important feature of the database tomography algorithm is that it can be used on a database of any size, and will facilitate the users ability to understand the volume of content therein. While employing the process to identify research opportunities it became obvious that this promising technology has potential applications for business, science, engineering, law, and academe. Examples include evaluating marketing trends, strategies, relationships and associations. Also, the database tomography process would be a powerful component in the area of competitive intelligence, national security intelligence and patent analysis. User interests and involvement cannot be overemphasized.

  11. MstApp, a rich client control applications framework at DESY

    The control systems for PETRA 3 (a dedicated synchrotron machine) and its pre-accelerators extensively use rich clients for the control room and the servers. Most of them are written with the help of a rich client Java framework: MstApp. They totalize 106 different consoles and 158 individual server applications. MstApp takes care of many common control system application aspects beyond communication. MstApp provides a common look and feel: core menu items, a colour scheme for standard states of hardware components and predefined standardized screen sizes/locations. It interfaces our console application manager (CAM) and displays on demand our communication link diagnostics tools. MstApp supplies an accelerator context for each application; it handles printing, logging, re-sizing and unexpected application crashes. Due to our standardized deploy process MstApp applications know their individual developers and can even send them - on button press of the users - E-mails. Further a concept of different operation modes is implemented: view only, operating and expert use. Administration of the corresponding rights is done via web access of a database server. Initialization files on a web server are instantiated as JAVA objects with the help of the Java SE XML-Decoder. Data tables are read with the same mechanism. New MstApp applications can easily be created with in house wizards like the NewProjectWizard or the DeviceServerWizard. MstApp improves the operator experience, application developer productivity and delivered software quality. (authors)

  15. Exchanging the Context between OGC Geospatial Web clients and GIS applications using Atom

    Maso, Joan; Díaz, Paula; Riverola, Anna; Pons, Xavier


    Currently, the discovery and sharing of geospatial information over the web still presents difficulties. News distribution through website content was simplified by the use of Really Simple Syndication (RSS) and Atom syndication formats. This communication exposes an extension of Atom to redistribute references to geospatial information in a Spatial Data Infrastructure distributed environment. A geospatial client can save the status of an application that involves several OGC services of different kind and direct data and share this status with other users that need the same information and use different client vendor products in an interoperable way. The extensibility of the Atom format was essential to define a format that could be used in RSS enabled web browser, Mass Market map viewers and emerging geospatial enable integrated clients that support Open Geospatial Consortium (OGC) services. Since OWS Context has been designed as an Atom extension, it is possible to see the document in common places where Atom documents are valid. Internet web browsers are able to present the document as a list of items with title, abstract, time, description and downloading features. OWS Context uses GeoRSS so that, the document can be to be interpreted by both Google maps and Bing Maps as items that have the extent represented in a dynamic map. Another way to explode a OWS Context is to develop an XSLT to transform the Atom feed into an HTML5 document that shows the exact status of the client view window that saved the context document. To accomplish so, we use the width and height of the client window, and the extent of the view in world (geographic) coordinates in order to calculate the scale of the map. Then, we can mix elements in world coordinates (such as CF-NetCDF files or GML) with elements in pixel coordinates (such as WMS maps, WMTS tiles and direct SVG content). A smarter map browser application called MiraMon Map Browser is able to write a context document and read

In this project provides a client side solution that uses a step by step approach to protect cross site scripting, without degrading much the userand#039;s web browsing experience.

  2. Research and application of ORACLE performance optimizing technologies for building airplane environment resource database

    Zhang, Jianjun; Sun, Jianyong; Cheng, Conggao


    Many problems exist in processing experimental aircraft vibration (temperature, humidity) data and generating the intermediate calculations during the construction of airplane environment resource database, such as the need to deal with both structural and non-structural data, weak capacity of the client browser for data processing and massive network data transferring etc. To solve the above problems, some strategies on tuning and optimization performance of database are employed base on Oracle11g, which include data storage structure tuning, the memory configuration of the server, the disk I/O tuning and SQL statement tuning. The experimental results show that the performance of airplane environment resource database is enhanced about 80% compared with the database developed in the initial demonstration and validation phase. The application of new optimization strategies to the database construction can lay a sound foundation for finishing building airplane environment resource database.

  7. How to Use a Desktop Version of a DBMS for Client-Server Applications

    Julian VASILEV


    DBMS (Data base management systems) still have a very high price for small and middle enterprises in Bulgaria. Desktop versions are free but they cannot function in multi-user environment. We will try to make an application server which will make a Desktop version of a DBMS open to many users. Thus, this approach will be appropriate for client-server applications. The author of the article gives a concise observation of the problem and a possible way of solution.

  8. Application of database systems in diabetes care.

    Kopelman, P G; Sanderson, A J


    The St Vincent Declaration includes a commitment to continuous quality improvement in diabetes care. This necessitates the collection of appropriate information to ensure that diabetes services are efficient, effective and equitable. The quantity of information, and the need for rapid access, means that this must be computer-based. The choice of architecture and the design of a database for diabetes care must take into account available equipment and operational requirements. Hardware topology may be determined by the operating system and/or netware software. An effective database system will include: user-friendliness, rapid but secure access to data, a facility for multiple selections for analysis and audit, the ability to be used as part of the patient consultation process, the ability to interface or integrate with other applications, and cost efficiency. An example of a clinical information database for diabetes care, Diamond, is described. PMID:9244825

  9. LISA, the next generation: from a web-based application to a fat client.

    Pierlet, Noëlla; Aerts, Werner; Vanautgaerden, Mark; Van den Bosch, Bart; De Deurwaerder, André; Schils, Erik; Noppe, Thomas


    The LISA application, developed by the University Hospitals Leuven, permits referring physicians to consult the electronic medical records of their patients over the internet in a highly secure way. We decided to completely change the way we secured the application, discard the existing web application and build a completely new application, based on the in-house developed hospital information system, used in the University Hospitals Leuven. The result is a fat Java client, running on a Windows Terminal Server, secured by a commercial SSL-VPN solution. PMID:18953122

  10. A Proposal of Client Application Architecture using Loosely Coupled Component Connection Method in Banking Branch System

    Someya, Harushi; Mori, Yuichi; Abe, Masahiro; Machida, Isamu; Hasegawa, Atsushi; Yoshie, Osamu

    Due to the deregulation of financial industry, the branches in banking industry need to shift to the sales-oriented bases from the operation-oriented bases. For corresponding to this movement, new banking branch systems are being developed. It is the main characteristics of new systems that we bring the form operations that have traditionally been performed at each branch into the centralized operation center for the purpose of rationalization and efficiency of the form operations. The branches treat a wide variety of forms. The forms can be described by common items in many cases, but the items include the different business logic and each form has the different relation among the items. And there is a need to develop the client application by user oneself. Consequently the challenge is to arrange the development environment that is high reusable, easy customizable and user developable. We propose a client application architecture that has a loosely coupled component connection method, and allows developing the applications by only describing the screen configurations and their transitions in XML documents. By adopting our architecture, we developed client applications of the centralized operation center for the latest banking branch system. Our experiments demonstrate good performances.

  12. Exemplary applications of the OECD fire database

    In general, the data from NPP experience with fire events stored in the OECD FIRE Database can provide answers to several interesting questions and insights on phenomena, such as examples of frequent fire initiators and their root causes, of electrical equipment failure modes, of fire protection equipment malfunctions, and of fire barriers impaired. Exemplary applications of the OECD FIRE Database show that it is already possible to retrieve reasonable qualitative information and to get to some extent also quantitative estimations, which can support the interpretation of the operating experience for specific events in the member countries participating in the OECD FIRE Project. The quantitative information will, of course, increase with the increasing number of reported events and a careful description of the respective events to provide as much information as available. In the third phase of the Project starting in 2010, the OECD FIRE Database will be further analyzed with respect to applications for first probabilistic safety assessment considerations, e.g. the positive and negative role of human factor in the fire ignition on the one hand, and, on the other hand, in fire detection and extinguishing. This has to be investigated in more detail to generate Fire PSA results with a higher confidence. Positive effects of human behavior for fire extinguishing are already identified in the existing Database. One of the main questions which could be answered by the OECD FIRE Database is how fires can propagate from the initial fire compartment to other compartments, even if there are protective means available for prevention of fire spreading. For generating meaningful event and fault trees for various safety significant fire scenarios, a clear and as far as possible detailed (with respect to time dependencies and safety significance) description of the initial fire event sequence and its consequences are essential. The coding of events has to reflect as far as feasible

  13. NSLS-II High Level Application Infrastructure And Client API Design

    The beam commissioning software framework of NSLS-II project adopts a client/server based architecture to replace the more traditional monolithic high level application approach. It is an open structure platform, and we try to provide a narrow API set for client application. With this narrow API, existing applications developed in different language under different architecture could be ported to our platform with small modification. This paper describes system infrastructure design, client API and system integration, and latest progress. As a new 3rd generation synchrotron light source with ultra low emittance, there are new requirements and challenges to control and manipulate the beam. A use case study and a theoretical analysis have been performed to clarify requirements and challenges to the high level applications (HLA) software environment. To satisfy those requirements and challenges, adequate system architecture of the software framework is critical for beam commissioning, study and operation. The existing traditional approaches are self-consistent, and monolithic. Some of them have adopted a concept of middle layer to separate low level hardware processing from numerical algorithm computing, physics modelling, data manipulating, plotting, and error handling. However, none of the existing approaches can satisfy the requirement. A new design has been proposed by introducing service oriented architecture technology. The HLA is combination of tools for accelerator physicists and operators, which is same as traditional approach. In NSLS-II, they include monitoring applications and control routines. Scripting environment is very important for the later part of HLA and both parts are designed based on a common set of APIs. Physicists and operators are users of these APIs, while control system engineers and a few accelerator physicists are the developers of these APIs. With our Client/Server mode based approach, we leave how to retrieve information to the

  17. AIDA Asia. Artificial Insemination Database Application

    The objectives of AIDA (Artificial Insemination Database Application) and its companion GAIDA (Guide to AI Data Analysis) are to address two major problems in on-farm research on livestock production. The first is the quality of the data collected and the second is the intellectual rigor of the analyses and their associated results when statistically testing causal hypotheses. The solution is to develop a data management system such as AIDA and an analysis system such as GAIDA to estimate parameters that explain biological mechanisms for on-farm application. The system uses epidemiological study designs in the uncontrolled research environment of the farm, uses a database manager (Microsoft Access) to handle data management issues encountered in preparing data for analysis, and then uses a statistical program (SYSTAT) to do preliminary analyses. These analyses enable the researcher to have better understanding of the biological mechanisms involved in the data contained within the AIDA database. Using GAIDA as a guide, this preliminary analysis helps to determine the strategy for further in-depth analyse

  19. Software Applications to Access Earth Science Data: Building an ECHO Client

    Cohen, A.; Cechini, M.; Pilone, D.


    Historically, developing an ECHO (NASA’s Earth Observing System (EOS) ClearingHOuse) client required interaction with its SOAP API. SOAP, as a framework for web service communication has numerous advantages for Enterprise applications and Java/C# type programming languages. However, as interest has grown for quick development cycles and more intriguing “mashups,” ECHO has seen the SOAP API lose its appeal. In order to address these changing needs, ECHO has introduced two new interfaces facilitating simple access to its metadata holdings. The first interface is built upon the OpenSearch format and ESIP Federated Search framework. The second interface is built upon the Representational State Transfer (REST) architecture. Using the REST and OpenSearch APIs to access ECHO makes development with modern languages much more feasible and simpler. Client developers can leverage the simple interaction with ECHO to focus more of their time on the advanced functionality they are presenting to users. To demonstrate the simplicity of developing with the REST API, participants will be led through a hands-on experience where they will develop an ECHO client that performs the following actions: + Login + Provider discovery + Provider based dataset discovery + Dataset, Temporal, and Spatial constraint based Granule discovery + Online Data Access

  4. NoSQL and SQL Databases for Mobile Applications. Case Study: MongoDB versus PostgreSQL

    Marin FOTACHE


    Full Text Available Compared with "classical" web, multi-tier applications, mobile applications have common and specific requirements concerning data persistence and processing. In mobile apps, database features can be distinctly analyzed for the client (minimalistic, isolated, memory-only and the server (data rich, centralized, distributed, synchronized and disk-based layers. Currently, a few lite relational database products reign the persistence for client platforms of mobile applications. There are two main objectives of this paper. First is to investigate storage options for major mobile platforms. Second is to point out some major differences between SQL and NoSQL datastores in terms of deployment, data model, schema design, data definition and manipulation. As NoSQL movement lacks standardization, from NoSQL products family MongoDB was chosen as reference, due to its strengths and popularity among developers. PostgreSQL serves the position of SQL DBMSs representative due to its popularity and conformity with SQL standards.

  6. Web application for detailed real-time database transaction monitoring for CMS condition data

    de Gruttola, Michele; Di Guida, Salvatore; Innocente, Vincenzo; Pierro, Antonio


    In the upcoming LHC era, database have become an essential part for the experiments collecting data from LHC, in order to safely store, and consistently retrieve, a wide amount of data, which are produced by different sources. In the CMS experiment at CERN, all this information is stored in ORACLE databases, allocated in several servers, both inside and outside the CERN network. In this scenario, the task of monitoring different databases is a crucial database administration issue, since different information may be required depending on different users' tasks such as data transfer, inspection, planning and security issues. We present here a web application based on Python web framework and Python modules for data mining purposes. To customize the GUI we record traces of user interactions that are used to build use case models. In addition the application detects errors in database transactions (for example identify any mistake made by user, application failure, unexpected network shutdown or Structured Query Language (SQL) statement error) and provides warning messages from the different users' perspectives. Finally, in order to fullfill the requirements of the CMS experiment community, and to meet the new development in many Web client tools, our application was further developed, and new features were deployed.

  7. Memory Storage Issues of Temporal Database Applications on Relational Database Management Systems

    Sami M. Halawani


    Full Text Available Problem statement: Many existing database applications manage time-varying data. These database applications are referred to as temporal databases or time-oriented database applications that are considered as repositories of time-dependent data. Many proposals have been introduced for developing time-oriented database applications, some of which suggest building support for Temporal Database Management Systems (TDBMS on top of existing non-temporal DBMSs, while others suggest modifying the models of exiting DBMSs or building TDBMS from scratch. Approach: This study addressed several issues concerning developing a technique that enables database designers to understand the way in which time-varying behavior can be modeled and mapped into tabular form. Results: Conventional DBMSs do not have the capability to record and process time-varying aspects of the real world. With growing sophistication of DBMS applications, the lack of temporal support in conventional DBMS raises serious problems when used to develop temporal database. The technique of understanding how to think about time and represent it in formal systems is the topic of this study. We examined how to implement time-varying application in the SQL structured query language by introducing temporal data concepts that need to be simulated in DBMSs which lack temporal supports. We proposed a temporal data model that combines the features of previous temporal models and that reduces the cost of memory storage. Conclusion: We proposed a technique for implementing temporal database on top of exiting non-temporal DBMS. This technique includes five main areas. These areas are temporal database conceptual design, temporal database logical design, integrity constraints preventions in temporal database, modifying and querying temporal database. We proposed a data model for the temporal database based on the data models which are discussed in literature.

  8. Databases and information systems: Applications in biogeography

    Some aspects of the new instrumentalization and methodological elements that make up information systems in biodiversity (ISB) are described. The use of accurate geographically referenced data allows a broad range of available sources: natural history collections and scientific literature require the use of databases and geographic information systems (GIS). The conceptualization of ISB and GIS, based in the use of extensive data bases, has implied detailed modeling and the construction of authoritative archives: exhaustive catalogues of nomenclature and synonymies, complete bibliographic lists, list of names proposed, historical-geographic gazetteers with localities and their synonyms united under a global positioning system which produces a geospheric conception of the earth and its biota. Certain difficulties in the development of the system and the construction of the biological databases are explained: quality control of data, for example. The use of such systems is basic in order to respond to many questions at the frontier of current studies of biodiversity and conservation. In particular, some applications in biogeography and their importance for modeling distributions, to identify and contrast areas of endemism and biological richness for conservation, and their use as tools in what we identify as predictive and experimental faunistics are detailed. Lastly, the process as well as its relevance is emphasized at national and regional levels

  10. Modular Workflow Engine for Distributed Services using Lightweight Java Clients

    Vetter, R -M; Peetz, J -V


    In this article we introduce the concept and the first implementation of a lightweight client-server-framework as middleware for distributed computing. On the client side an installation without administrative rights or privileged ports can turn any computer into a worker node. Only a Java runtime environment and the JAR files comprising the workflow client are needed. To connect all clients to the engine one open server port is sufficient. The engine submits data to the clients and orchestrates their work by workflow descriptions from a central database. Clients request new task descriptions periodically, thus the system is robust against network failures. In the basic set-up, data up- and downloads are handled via HTTP communication with the server. The performance of the modular system could additionally be improved using dedicated file servers or distributed network file systems. We demonstrate the design features of the proposed engine in real-world applications from mechanical engineering. We have used ...

  18. Exploring client logs towards characterizing the user behavior on web applications

    Guarino de Vasconcelos, Leandro; Coelho dos Santos, Rafael D.; Baldochi, Laercio A.


    Analysis of user interaction with computer systems can be used for several purposes, the most common being analysis of the effectiveness of the interfaces used for interaction (in order to adapt or enhance its usefulness) and analysis of intention and behavior of the users when interacting with these systems. For web applications, often the analysis of user interaction is done using the web server logs collected for every document sent to the user in response to his/her request. In order to capture more detailed data on the users' interaction with sites, one could collect actions the user performs in the client side. An effective approach to this is the USABILICS system, which also allows the definition and analysis of tasks in web applications. The fine granularity of logs collected by USABILICS allows a much more detailed log of users' interaction with a web application. These logs can be converted into graphs where vertices are users' actions and edges are paths made by the user to accomplish a task. Graph analysis and visualization tools and techniques allow the analysis of actions taken in relation to an expected action path, or characterization of common (and uncommon) paths on the interaction with the application. This paper describes how to estimate users' behavior and characterize their intentions during interaction with a web application, presents the analysis and visualization tools on those graphs and shows some practical results with an educational site, commenting on the results and implications of the possibilities of using these techniques.

  6. Heterogeneous Database integration for Web Applications

    V. Rajeswari


    Full Text Available In the contemporary business and industrial environment, the variety of data used by organizations are increasing rapidly. Also, there is an increasing demand for accessing this data. The size, complexity and variety of databases used for data handling cause serious problems in manipulating this distributed information. Integrating all the information from different databases into one database is a challenging problem. XML has been in use in recent times to handle data in web appliccations. XML (eXtensible Markup Language is a very open way of data communication. XML has become the undisputable standard both for data exchange and content management. XML is supported by the giants of the software industry like IBM, Oracle and Microsoft. The XML markup language should be the lingua franca of data interchange; but it’s rate of acceptance has been limited by a mismatch between XML and legacy databases. This in turn, has created a need for a mapping tool to integrate the XML and databases. This paper highlights the merging of heterogeneous database resource. This can be achieved by means of conversion of relational mode to XML schema and vice versa and by adding the semantic constraints to the XML Schema. The developments that the industry has seen in recent times in this field is referred to as the basis.

  7. Field installation of a distributed database application

    APC-based equipment failure reporting system was designed as a distributed database over a Wide Area Network. Speed related communication problems were encountered, necessitating a redesign of the program. In the original design, data for local failures was to reside in several local field offices. Division level reporting was to be accomplished by concatenating the field offices' databases over the network. Validation information was to reside in several small databases located on the division file server. This data was to be accessed by the field offices as a remote link. The program executables were to reside on yet another file server belonging to the service organization which maintained the program code. Both the field an division offices were to access the program code as a remote link. This paper discusses the network and communications facilities which were in place, the original design, the performance encountered, the design changes and present performance. There is also a brief discussion of possible future modifications

  10. Client Perspective

    Training Sections can best serve the needs of their clients by encouraging them to recognize that self-determination and overall training program ownership are the key ingredients of a successful program. In a support role, Training Sections should provide excellent lesson plans and instructors, good record keeping, and feedback vehicles. Most importantly, Training Sections should communicate closely with their clients and provide maximum flexibility to support overall client responsibilities

  11. A thermodynamic database for geophysical applications

    Saxena, S. K.


    Several thermodynamic databases are available for calculation of equilibrium reference state of the model earth. Prominent among these are the data bases of (a) SLB (1), (b) HP (2) and (c) FSPW (3). The two major problems, as discussed in a meeting of the database scientists (4), lie in the formulation of solid solutions and equations of state. The models adopted in databases (1) and (2) do not account for multi-components in natural solids and the sub-lattice or compound-energy models used in (3) require lot of fictive compound and mixing energy data for which there is no present ongoing attempt. The EOS formulation in (1) is based on Mie-Gruneisen equation of state and in (2) on modification of Tait EOS with limited parameters. The database (3) adopted the Birch-Murnaghan EOS and used it for high temperature by making compressibility a function of temperature. The (2) and (3) models lead to physically unacceptable values of entropy and heat capacity at extreme conditions. The problem is as much associated with the EOS formulation as with the adoption of a heat capacity change with temperature at 1 bar as discussed by Brosh (5). None of the databases (1), (2) or (3) include the database on multicomponent fluid at extreme conditions. These problems have been addressed in the new database modified after (3). It retains the solution models for solids as in (3) and adds the Brosh Model (5) for solid solutions and the Belonoshko et al (6) model for 13-component C-H-O-S fluid. The Superfluid model builds on the combination of experimental data on pure and mixed fluids at temperatures lower than 1000 K over several kilobars and molecular dynamics generated data at extreme conditions and has been found to be consistent with all the recent experimental data. New high pressure experiments on dissociation of volatile containing solids using laser- and externally-heated DAC are being conducted to obtain new pressure-volume-temperature data on fluids to extend the current kb

    In-Sung Cho; Seung-Mok Yoo; Chae-Ho Lim; Jeong-Kil Choi


    Construction of integrated database including casting shapes with their casting design, technical knowledge, and thermophysical properties of the casting alloys were introduced in the present study. Recognition tech- nique for casting design by industrial computer tomography was used for the construction of shape database. Technical knowledge of the casting processes such as ferrous and non-ferrous alloys and their manufacturing process of the castings were accumulated and the search engine for the knowledge was developed. Database of thermophysical properties of the casting alloys were obtained via the experimental study, and the properties were used for .the in-house computer simulation of casting process. The databases were linked with intelligent casting expert system developed in center for e-design, KITECH. It is expected that the databases can help non casting experts to devise the casting and its process. Various examples of the application by using the databases were shown in the present study.

  16. Patterns of client behavior with their most recent male escort: an application of latent class analysis.

    Grov, Christian; Starks, Tyrel J; Wolff, Margaret; Smith, Michael D; Koken, Juline A; Parsons, Jeffrey T


    Research examining interactions between male escorts and clients has relied heavily on data from escorts, men working on the street, and behavioral data aggregated over time. In the current study, 495 clients of male escorts answered questions about sexual behavior with their last hire. Latent class analysis identified four client sets based on these variables. The largest (n = 200, 40.4 %, labeled Typical Escort Encounter) included men endorsing behavior prior research found typical of paid encounters (e.g., oral sex and kissing). The second largest class (n = 157, 31.7 %, Typical Escort Encounter + Erotic Touching) included men reporting similar behaviors, but with greater variety along a spectrum of touching (e.g., mutual masturbation and body worship). Those classed BD/SM and Kink (n = 76, 15.4 %) reported activity along the kink spectrum (BD/SM and role play). Finally, men classed Erotic Massage Encounters (n = 58, 11.7 %) primarily engaged in erotic touch. Clients reporting condomless anal sex were in the minority (12.2 % overall). Escorts who engage in anal sex with clients might be appropriate to train in HIV prevention and other harm reduction practices-adopting the perspective of "sex workers as sex educators."

  17. Analysis of Turbulence Datasets using a Database Cluster: Requirements, Design, and Sample Applications

    Meneveau, Charles


    The massive datasets now generated by Direct Numerical Simulations (DNS) of turbulent flows create serious new challenges. During a simulation, DNS provides only a few time steps at any instant, owing to storage limitations within the computational cluster. Therefore, traditional numerical experiments done during the simulation examine each time slice only a few times before discarding it. Conversely, if a few large datasets from high-resolution simulations are stored, they are practically inaccessible to most in the turbulence research community, who lack the cyber resources to handle the massive amounts of data. Even those who can compute at that scale must run simulations again forward in time in order to answer new questions about the dynamics, duplicating computational effort. The result is that most turbulence datasets are vastly underutilized and not available as they should be for creative experimentation. In this presentation, we discuss the desired features and requirements of a turbulence database that will enable its widest access to the research community. The guiding principle of large databases is ``move the program to the data'' (Szalay et al. ``Designing and mining multi-terabyte Astronomy archives: the Sloan Digital Sky Survey,'' in ACM SIGMOD, 2000). However, in the case of turbulence research, the questions and analysis techniques are highly specific to the client and vary widely from one client to another. This poses particularly hard challenges in the design of database analysis tools. We propose a minimal set of such tools that are of general utility across various applications. And, we describe a new approach based on a Web services interface that allows a client to access the data in a user-friendly fashion while allowing maximum flexibility to execute desired analysis tasks. Sample applications will be discussed. This work is performed by the interdisciplinary ITR group, consisting of the author and Yi Li(1), Eric Perlman(2), Minping Wan(1

  18. Database applications in high energy physics

    High Energy physicists were using computers to process and store their data early in the history of computing. They addressed problems of memory management, job control, job generation, data standards, file conventions, multiple simultaneous usage, tape file handling and data management earlier than, or at the same time as, the manufacturers of computing equipment. The HEP community have their own suites of programs for these functions, and are now turning their attention to the possibility of replacing some of the functional components of their 'homebrew' systems with more widely used software and/or hardware. High on the 'shopping list' for replacement is data management. ECFA Working Group 11 has been working on this problem. This paper reviews the characteristics of existing HEP systems and existing database systems and discusses the way forward. (orig.)

  19. Application of the device database in the Python programming

    The Device Database has been developed using the relational database in the KEKB accelerator control system. It contains many kinds of parameters of the devices, mainly magnets and magnet power supplies. The parameters consist of the wiring information, the address of the interfaces, the specification of the hardware, the calibration constants, the magnetic field excitation functions and the any other parameters for the device control. These parameters are necessary not only for constructing EPICS IOC database but also for providing information to the high-level application programs, most of which are written in the script languages such as SAD or Python. Particularly Python is often used to access the Device Database. For this purpose, the Python library module that is designed to handle tabular data of the relational database on memory has been developed. The overview of the library module is reported. (author)

  1. A relational database application in support of integrated neuroscience research.

    Rudowsky, Ira; Kulyba, Olga; Kunin, Mikhail; Ogarodnikov, Dmitri; Raphan, Theodore


    The development of relational databases has significantly improved the performance of storage, search, and retrieval functions and has made it possible for applications that perform real-time data acquisition and analysis to interact with these types of databases. The purpose of this research was to develop a user interface for interaction between a data acquisition and analysis application and a relational database using the Oracle9i system. The overall system was designed to have an indexing capability that threads into the data acquisition and analysis programs. Tables were designed and relations within the database for indexing the files and information contained within the files were established. The system provides retrieval capabilities over a broad range of media, including analog, event, and video data types. The system's ability to interact with a data capturing program at the time of the experiment to create both multimedia files as well as the meta-data entries in the relational database avoids manual entries in the database and ensures data integrity and completeness for further interaction with the data by analysis applications.

  4. Contracting preference relations for database applications

    Mindolin, Denis; Chomicki, Jan


    The binary relation framework has been shown to be applicable to many real-life preference handling scenarios. Here we study preference contraction: the problem of discarding selected preferences. We argue that the property of minimality and the preservation of strict partial orders are crucial for contractions. Contractions can be further constrained by specifying which preferences should be protected. We consider two classes of preference relations: finite and finitely representable. We pre...

    WANGWen; ZHANGZHi-ming; 等


    The technique of non-stationary oll film force database for hydrodynamic bearing is introduced and its potential applications in nonlinear rotor-dynamics are demonstrated.Through simulations of the locus of the shaft center aided by the database technique,nonlinear stability analysis can be performed and the natural frequency can be obtained as well.The easiness of “assembling” the individual bush forces from the database to form the bearing force.makes it very convenient to evaluate the stability of various types of journal bearings,Examples are demonstrated to show how the database technique makes it possible to get technically abundant simulation results at the expense of very short calculation time.

  6. Database Replication

    Kemme, Bettina


    Database replication is widely used for fault-tolerance, scalability and performance. The failure of one database replica does not stop the system from working as available replicas can take over the tasks of the failed replica. Scalability can be achieved by distributing the load across all replicas, and adding new replicas should the load increase. Finally, database replication can provide fast local access, even if clients are geographically distributed clients, if data copies are located close to clients. Despite its advantages, replication is not a straightforward technique to apply, and

  7. A Green's function database platform for seismological research and education: applications and examples

    Heimann, Sebastian; Kriegerowski, Marius; Dahm, Torsten; Simone, Cesca; Wang, Rongjiang


    The study of seismic sources from measured waveforms requires synthetic elementary seismograms (Green's functions, GF) calculated for specific earth models and source receiver geometries. Since the calculation of GFs is computationally expensive and requires careful parameter testing and quality control, pre-calculated GF databases, which can be re-used for different types of applications, can be of advantage. We developed a GF database web platform for the seismological community (, where a researcher can share Green's function stores and retrieve synthetic seismograms on the fly for various point and extended earthquake source models for many different earth models at local, regional and global scale. This web service is part of a rich new toolset for the creation and handling of Green's functions and synthetic seismograms ( It can be used off-line or in client mode. We demonstrate core features of the GF platform with different applications on global, regional and local scales. These include the automatic inversion of kinematic source parameter from teleseismic body waves, the improved depth estimate of shallow induced earthquakes from regional seismological arrays, or the relative moment tensor inversion of local earthquakes from volcanic induced seismicity.

  8. Molten salts database for energy applications

    Serrano-López, Roberto; Cuesta-López, Santiago


    The growing interest in energy applications of molten salts is justified by several of their properties. Their possibilities of usage as a coolant, heat transfer fluid or heat storage substrate, require thermo-hydrodynamic refined calculations. Many researchers are using simulation techniques, such as Computational Fluid Dynamics (CFD) for their projects or conceptual designs. The aim of this work is providing a review of basic properties (density, viscosity, thermal conductivity and heat capacity) of the most common and referred salt mixtures. After checking data, tabulated and graphical outputs are given in order to offer the most suitable available values to be used as input parameters for other calculations or simulations. The reviewed values show a general scattering in characterization, mainly in thermal properties. This disagreement suggests that, in several cases, new studies must be started (and even new measurement techniques should be developed) to obtain accurate values.

    Nick Ryan


    Full Text Available Databases are deeply embedded in archaeology, underpinning and supporting many aspects of the subject. However, as well as providing a means for storing, retrieving and modifying data, databases themselves must be a result of a detailed analysis and design process. This article looks at this process, and shows how the characteristics of data models affect the process of database design and implementation. The impact of the Internet on the development of databases is examined, and the article concludes with a discussion of a range of issues associated with the recording and management of archaeological data.

  11. Development of Integrated PSA Database and Application Technology

    The high quality of PSA is essential for the risk informed regulation and applications. The main elements of PSA are the model, methodology, reliability data, and tools. The purpose of the project is to develop the reliability database for the Korean nuclear power plants and PSA analysis and management system. The reliability database system has been developed and the reliability data has been collected for 4 types of reliability data such as the reactor trip, the piping, the component and the common cause failure. The database provides the reliability data for PSAs and risk informed applications. The FTREX software is the fastest PSA quantification engine in the world. The license agreement between KAERI and EPRI is made to sell FTREX to the members of EPRI. The advanced PSA management system AIMS- PSA has been developed. The PSA model is stored in the database and solved by clicking one button. All the information necessary for the KSNP Level-1 and 2 PSA is stored in the PSA information database. It provides the PSA users a useful mean to review and analyze the PSA

  12. Mapper: A distributed object-oriented database application

    Younger, Herbert; O'Reilly, John; Frogner, Bjorn


    This paper discusses the results of a Small Business Innovation Research (SBIR) project. The initial application involved decomposition of a large database across multiple processors to improve the speed of processing compound queries. The commercial outcome was a tourist information system with a point-to-point driving direction program called MAPPER. A distributed, object-oriented approach was used for the general design, while a spatial decomposition was used to divide the database into computationally manageable pieces. The resulting system is highly flexible with respect to both modifications and reuse.

  13. An integrated medical image database and retrieval system using a web application server.

    Cao, Pengyu; Hashiba, Masao; Akazawa, Kouhei; Yamakawa, Tomoko; Matsuto, Takayuki


    We developed an Integrated Medical Image Database and Retrieval System (INIS) for easy access by medical staff. The INIS mainly consisted of four parts: specific servers to save medical images from multi-vendor modalities of CT, MRI, CR, ECG and endoscopy; an integrated image database (DB) server to save various kinds of images in a DICOM format; a Web application server to connect clients to the integrated image DB and the Web browser terminals connected to an HIS system. The INIS provided a common screen design to retrieve CT, MRI, CR, endoscopic and ECG images, and radiological reports, which would allow doctors to retrieve radiological images and corresponding reports, or ECG images of a patient simultaneously on a screen. Doctors working in internal medicine on average accessed information 492 times a month. Doctors working in cardiological and gastroenterological accessed information 308 times a month. Using the INIS, medical staff could browse all or parts of a patient's medical images and reports. PMID:12909158

  14. Database application for changing data models in environmental engineering

    Hussels, Ulrich; Camarinopoulos, Stephanos; Luedtke, Torsten; Pampoukis, Georgios [RISA Sicherheitsanalysen GmbH, Berlin-Charlottenburg (Germany)


    Whenever a technical task is to be solved with the help of a database application and uncertainties regarding the structure, scope or level of detail of the data model exist (either currently or in the future) the use of a generic database application can reduce considerably the cost of implementation and maintenance. Simultaneously the approach described in this contribution permits the operation with different views on the data and even finding and defining new views which had not been considered before. The prerequisite for this is that the preliminary information (structure as well as data) stored into the generic application matches the intended use. In this case, parts of the generic model developed with the generic approach can be reused and according efforts for a major rebuild can be saved. This significantly reduces the development time. At the same time flexibility is achieved concerning the environmental data model, which is not given in the context of conventional developments. (orig.)

  15. Current research status, databases and application of single nucleotide polymorphism.

    Javed, R; Mukesh


    Single Nucleotide Polymorphisms (SNPs) are the most frequent form of DNA variation in the genome. SNPs are genetic markers which are bi-allelic in nature and grow at a very fast rate. Current genomic databases contain information on several million SNPs. More than 6 million SNPs have been identified and the information is publicly available through the efforts of the SNP Consortium and others data bases. The NCBI plays a major role in facillating the identification and cataloging of SNPs through creation and maintenance of the public SNP database (dbSNP) by the biomedical community worldwide and stimulate many areas of biological research including the identification of the genetic components of disease. In this review article, we are compiling the existing SNP databases, research status and their application. PMID:21717869

    Chi, Andrew; Cochran, Robert; Nesfield, Marie; Reiter, Michael K.; Sturton, Cynthia


    Numerous exploits of client-server protocols and applications involve modifying clients to behave in ways that untampered clients would not, such as crafting malicious packets. In this paper, we demonstrate practical verification of a cryptographic protocol client's messaging behavior as being consistent with the client program it is believed to be running. Moreover, we accomplish this without modifying the client in any way, and without knowing all of the client-side inputs driving its behav...

    Client database updating refers to the process of utilizing the related information of the changed and updated features in the new version of fundamental geographical information database to perform the corresponding cascade updates on client database for ensuring it also has good currency. The current researches emphasize particularly on the distribution and delivery of updating information, but how to efficiently implement the updating of client database,especially in the case of semantic heterogeneity, doesn't be considered fully. Aiming to this problem, the semantic heterogeneities between two databases are firstly summarized, and then their impacts on the updating implementation process are described from some aspects such as efficiency, the completeness, the consistency and correctness of data. Finally, the updating implementation model consisted of three basic operations, semantic matching, updates extraction and updates integration, is proposed according to the theory of semantic mapping and transformation, and the execution strategies and key steps of these operations are respectively discussed. Through these discussions and analysis, the concept of fundamental geoqnformation client database updating, its implementation requirements and technical difficulties, the corresponding solutions, the key problems needed to be further researched are made clean Based on the current works and the future researches,an automated and efficient software tool for client database updating is promising to be developed and realized.%客户数据库更新就是利用新版基础地理数据库中更新变化的要素信息,对客户数据库进行相应的级联更新,以使其具有良好现势性的过程.现有研究大多侧重于基础地理数据库更新信息的分发与提供,而没有充分考虑语义差异环境下如何高效实施客户数据库更新的具体问题.针对此,该文概括了基础地理数据库与其客户数据库之间潜在的各种语义

  1. Design and implementation of a cartographic client application for mobile devices using SVG Tiny and J2ME

    Hui, L.; Behr, F.-J.; Schröder, D.


    The dissemination of digital geospatial data is available now on mobile devices such as PDAs (personal digital assistants) and smart-phones etc. The mobile devices which support J2ME (Java 2 Micro Edition) offer users and developers one open interface, which they can use to develop or download the software according their own demands. Currently WMS (Web Map Service) can afford not only traditional raster image, but also the vector image. SVGT (Scalable Vector Graphics Tiny) is one subset of SVG (Scalable Vector Graphics) and because of its precise vector information, original styling and small file size, SVGT format is fitting well for the geographic mapping purpose, especially for the mobile devices which has bandwidth net connection limitation. This paper describes the development of a cartographic client for the mobile devices, using SVGT and J2ME technology. Mobile device will be simulated on the desktop computer for a series of testing with WMS, for example, send request and get the responding data from WMS and then display both vector and raster format image. Analyzing and designing of System structure such as user interface and code structure are discussed, the limitation of mobile device should be taken into consideration for this applications. The parsing of XML document which is received from WMS after the GetCapabilities request and the visual realization of SVGT and PNG (Portable Network Graphics) image are important issues in codes' writing. At last the client was tested on Nokia S40/60 mobile phone successfully.

  2. Mining the Galaxy Zoo Database: Machine Learning Applications

    Borne, Kirk D.; Wallin, J.; Vedachalam, A.; Baehr, S.; Lintott, C.; Darg, D.; Smith, A.; Fortson, L.


    The new Zooniverse initiative is addressing the data flood in the sciences through a transformative partnership between professional scientists, volunteer citizen scientists, and machines. As part of this project, we are exploring the application of machine learning techniques to data mining problems associated with the large and growing database of volunteer science results gathered by the Galaxy Zoo citizen science project. We will describe the basic challenge, some machine learning approaches, and early results. One of the motivators for this study is the acquisition (through the Galaxy Zoo results database) of approximately 100 million classification labels for roughly one million galaxies, yielding a tremendously large and rich set of training examples for improving automated galaxy morphological classification algorithms. In our first case study, the goal is to learn which morphological and photometric features in the Sloan Digital Sky Survey (SDSS) database correlate most strongly with user-selected galaxy morphological class. As a corollary to this study, we are also aiming to identify which galaxy parameters in the SDSS database correspond to galaxies that have been the most difficult to classify (based upon large dispersion in their volunter-provided classifications). Our second case study will focus on similar data mining analyses and machine leaning algorithms applied to the Galaxy Zoo catalog of merging and interacting galaxies. The outcomes of this project will have applications in future large sky surveys, such as the LSST (Large Synoptic Survey Telescope) project, which will generate a catalog of 20 billion galaxies and will produce an additional astronomical alert database of approximately 100 thousand events each night for 10 years -- the capabilities and algorithms that we are exploring will assist in the rapid characterization and classification of such massive data streams. This research has been supported in part through NSF award #0941610.

  3. Advancements in web-database applications for rabies surveillance

    Bélanger Denise


    Full Text Available Abstract Background Protection of public health from rabies is informed by the analysis of surveillance data from human and animal populations. In Canada, public health, agricultural and wildlife agencies at the provincial and federal level are responsible for rabies disease control, and this has led to multiple agency-specific data repositories. Aggregation of agency-specific data into one database application would enable more comprehensive data analyses and effective communication among participating agencies. In Québec, RageDB was developed to house surveillance data for the raccoon rabies variant, representing the next generation in web-based database applications that provide a key resource for the protection of public health. Results RageDB incorporates data from, and grants access to, all agencies responsible for the surveillance of raccoon rabies in Québec. Technological advancements of RageDB to rabies surveillance databases include 1 automatic integration of multi-agency data and diagnostic results on a daily basis; 2 a web-based data editing interface that enables authorized users to add, edit and extract data; and 3 an interactive dashboard to help visualize data simply and efficiently, in table, chart, and cartographic formats. Furthermore, RageDB stores data from citizens who voluntarily report sightings of rabies suspect animals. We also discuss how sightings data can indicate public perception to the risk of racoon rabies and thus aid in directing the allocation of disease control resources for protecting public health. Conclusions RageDB provides an example in the evolution of spatio-temporal database applications for the storage, analysis and communication of disease surveillance data. The database was fast and inexpensive to develop by using open-source technologies, simple and efficient design strategies, and shared web hosting. The database increases communication among agencies collaborating to protect human health from

  4. Group-oriented coordination models for distributed client-server computing

    Adler, Richard M.; Hughes, Craig S.


    This paper describes group-oriented control models for distributed client-server interactions. These models transparently coordinate requests for services that involve multiple servers, such as queries across distributed databases. Specific capabilities include: decomposing and replicating client requests; dispatching request subtasks or copies to independent, networked servers; and combining server results into a single response for the client. The control models were implemented by combining request broker and process group technologies with an object-oriented communication middleware tool. The models are illustrated in the context of a distributed operations support application for space-based systems.

  6. Application Program Interface for the Orion Aerodynamics Database

    Robinson, Philip E.; Thompson, James


    The Application Programming Interface (API) for the Crew Exploration Vehicle (CEV) Aerodynamic Database has been developed to provide the developers of software an easily implemented, fully self-contained method of accessing the CEV Aerodynamic Database for use in their analysis and simulation tools. The API is programmed in C and provides a series of functions to interact with the database, such as initialization, selecting various options, and calculating the aerodynamic data. No special functions (file read/write, table lookup) are required on the host system other than those included with a standard ANSI C installation. It reads one or more files of aero data tables. Previous releases of aerodynamic databases for space vehicles have only included data tables and a document of the algorithm and equations to combine them for the total aerodynamic forces and moments. This process required each software tool to have a unique implementation of the database code. Errors or omissions in the documentation, or errors in the implementation, led to a lengthy and burdensome process of having to debug each instance of the code. Additionally, input file formats differ for each space vehicle simulation tool, requiring the aero database tables to be reformatted to meet the tool s input file structure requirements. Finally, the capabilities for built-in table lookup routines vary for each simulation tool. Implementation of a new database may require an update to and verification of the table lookup routines. This may be required if the number of dimensions of a data table exceeds the capability of the simulation tools built-in lookup routines. A single software solution was created to provide an aerodynamics software model that could be integrated into other simulation and analysis tools. The highly complex Orion aerodynamics model can then be quickly included in a wide variety of tools. The API code is written in ANSI C for ease of portability to a wide variety of systems. The

  7. AIDA Asia. Artificial Insemination Database Application. User manual. 1

    Artificial Insemination Database Application (AIDA-Asia) is a computer application to store and analyze information from AI Services (farms, females, inseminated, semen, estrus characteristics, inseminator and pregnancy diagnosis data). The need for such an application arose during a consultancy undertaken by the author for the International Atomic Energy Agency (IAEA, Vienna) under the framework of its Regional Co-operative Agreement for Asia and the Pacific (RCA) which is implementing a project on 'Improving Animal Productivity and Reproductive Efficiency' (RAS/5/035). The detailed specifications for the application were determined through a Task Force Meeting of National Consultants from five RCA Member States, organized by the IAEA and held in Sri Lanka in April 2001. The application has been developed in MS Access 2000 and Visual Basic for Applications (VBA) 6.0. However, it can run as a stand-alone application through its own executable files. It is based on screen forms for data entry or editing of information and command buttons. The structure of the data, the design of the application and VBA codes cannot be seen and cannot be modified by users. However, the designated administrator of AIDA-Asia in each country can customize it

  15. Development of application program and building database to increase facilities for using the radiation effect assessment computer codes

    The current radiation effect assessment system is required the skillful technique about the application for various code and high level of special knowledge classified by field. Therefore, as a matter of fact, it is very difficult for the radiation users' who don't have enough special knowledge to assess or recognize the radiation effect properly. For this, we already have developed the five Computer codes(windows-based), that is the radiation effect assessment system, in radiation utilizing field including the nuclear power generation. It needs the computer program that non-specialist can use the five computer codes to have already developed with ease. So, we embodied the A.I-based specialist system that can infer the assessment system by itself, according to the characteristic of given problem. The specialist program can guide users, search data, inquire of administrator directly. Conceptually, with circumstance which user to apply the five computer code may encounter actually, we embodied to consider aspects as follows. First, the accessibility of concept and data to need must be improved. Second, the acquirement of reference theory and use of corresponding computer code must be easy. Third, Q and A function needed for solution of user's question out of consideration previously. Finally, the database must be renewed continuously. Actually, to express this necessity, we develop the client program to organize reference data, to build the access methodology(query) about organized data, to load the visible expression function of searched data. And It is embodied the instruction method(effective theory acquirement procedure and methodology) to acquire the theory referring the five computer codes. It is developed the data structure access program(DBMS) to renew continuously data with ease. For Q and A function, it is embodied the Q and A board within client program because the user of client program can search the content of question and answer. (authors)

  17. Application of modern reliability database techniques to military system data

    Bunea, Cornel [Department of Engineering Management and Systems Engineering, George Washington University, 1776 G Street, NW, Suite 9, Washington, DC 20052 (United States)], E-mail:; Mazzuchi, Thomas A.; Sarkani, Shahram; Chang, H.-C. [Department of Engineering Management and Systems Engineering, The George Washington University, 1776 G Street, NW, Suite 9, Washington, DC 20052 (United States)


    This paper focuses on analysis techniques of modern reliability databases, with an application to military system data. The analysis of military system data base consists of the following steps: clean the data and perform operation on it in order to obtain good estimators; present simple plots of data; analyze the data with statistical and probabilistic methods. Each step is dealt with separately and the main results are presented. Competing risks theory is advocated as the mathematical support for the analysis. The general framework of competing risks theory is presented together with simple independent and dependent competing risks models available in literature. These models are used to identify the reliability and maintenance indicators required by the operating personnel. Model selection is based on graphical interpretation of plotted data.

    Takahiro, Suzuki; Shunsuke, Doi; Yutaka, Hatakeyama; Masayuki, Honda; Yasushi, Matsumura; Gen, Shimada; Mitsuhiro, Takasaki; Shusaku, Tsumoto; Hideto, Yokoi; Katsuhiko, Takabayashi


    We performed the multi-year project to collect discharge summary from multiple hospitals and made the big text database to build a common document vector space, and developed various applications. We extracted 243,907 discharge summaries from seven hospitals. There was a difference in term structure and number of terms between the hospitals, however the differences by disease were similar. We built the vector space using TF-IDF method. We performed a cross-match analysis of DPC selection among seven hospitals. About 80% cases were correctly matched. The use of model data of other hospitals reduced selection rate to around 10%; however, integrated model data from all hospitals restored the selection rate. PMID:26262419

  19. Multimedia Database Applications: Issues and Concerns for Classroom Teaching

    Yu, Chien


    The abundance of multimedia data and information is challenging educators to effectively search, browse, access, use, and store the data for their classroom teaching. However, many educators could still be accustomed to teaching or searching for information using conventional methods, but often the conventional methods may not function well with multimedia data. Educators need to efficiently interact and manage a variety of digital media files too. The purpose of this study is to review current multimedia database applications in teaching and learning, and further discuss some of the issues or concerns that educators may have while incorporating multimedia data into their classrooms. Some strategies and recommendations are also provided in order for educators to be able to use multimedia data more effectively in their teaching environments.

  20. Applications of the Cambridge Structural Database in chemical education.

    Battle, Gary M; Ferrence, Gregory M; Allen, Frank H


    The Cambridge Structural Database (CSD) is a vast and ever growing compendium of accurate three-dimensional structures that has massive chemical diversity across organic and metal-organic compounds. For these reasons, the CSD is finding significant uses in chemical education, and these applications are reviewed. As part of the teaching initiative of the Cambridge Crystallographic Data Centre (CCDC), a teaching subset of more than 500 CSD structures has been created that illustrate key chemical concepts, and a number of teaching modules have been devised that make use of this subset in a teaching environment. All of this material is freely available from the CCDC website, and the subset can be freely viewed and interrogated using WebCSD, an internet application for searching and displaying CSD information content. In some cases, however, the complete CSD System is required for specific educational applications, and some examples of these more extensive teaching modules are also discussed. The educational value of visualizing real three-dimensional structures, and of handling real experimental results, is stressed throughout. PMID:20877495

  1. Web Application Software for Ground Operations Planning Database (GOPDb) Management

    Lanham, Clifton; Kallner, Shawn; Gernand, Jeffrey


    A Web application facilitates collaborative development of the ground operations planning document. This will reduce costs and development time for new programs by incorporating the data governance, access control, and revision tracking of the ground operations planning data. Ground Operations Planning requires the creation and maintenance of detailed timelines and documentation. The GOPDb Web application was created using state-of-the-art Web 2.0 technologies, and was deployed as SaaS (Software as a Service), with an emphasis on data governance and security needs. Application access is managed using two-factor authentication, with data write permissions tied to user roles and responsibilities. Multiple instances of the application can be deployed on a Web server to meet the robust needs for multiple, future programs with minimal additional cost. This innovation features high availability and scalability, with no additional software that needs to be bought or installed. For data governance and security (data quality, management, business process management, and risk management for data handling), the software uses NAMS. No local copy/cloning of data is permitted. Data change log/tracking is addressed, as well as collaboration, work flow, and process standardization. The software provides on-line documentation and detailed Web-based help. There are multiple ways that this software can be deployed on a Web server to meet ground operations planning needs for future programs. The software could be used to support commercial crew ground operations planning, as well as commercial payload/satellite ground operations planning. The application source code and database schema are owned by NASA.



    Now GIS is turning into a good tool in handling geographical, economical, and population data, so we can obtain more and more information from these data. On the other hand, in some cases, for a calamity, such as hurricane, earthquake, flood, drought etc., or a decision-making, such as setting up a broadcasting transmitter, building a chemical plant etc., we have to evaluate the total population in the region influenced by a calamity or a project. In this paper, a method is put forward to evaluate the population in such special region. Through exploring the correlation of geographical parameters and the distribution of people in the same region by means of quantitative analysis and qualitative analysis, unit population database (1km× 1km) is established. In this way, estimating the number of people in a special region is capable by adding up the population in every grid involved in this region boundary. The geographical parameters are obtained from topographic database and DEM database on the scale of 1∶ 250 000. The fundamental geographical parameter database covering county administrative boundaries and 1km× 1km grid is set up and the population database at county level is set up as well. Both geographical parameter database and unit population database are able to offer sufficient conditions for quantitative analysis. They will have important role in the research fields of data mining (DM), Decision-making Support Systems (DSS), and regional sustainable development.

  5. TOPCAT's TAP Client

    Taylor, Mark


    TAP, the Table Access Protocol, is a Virtual Observatory (VO) protocol for executing queries in remote relational databases using ADQL, an SQL-like query language. It is one of the most powerful components of the VO, but also one of the most complex to use, with an extensive stack of associated standards. We present here recent improvements to the client and GUI for interacting with TAP services from the TOPCAT table analysis tool. As well as managing query submission and result retrieval, the GUI attempts to provide the user with as much help as possible in locating services, understanding service metadata and capabilities, and constructing correct and useful ADQL queries. The implementation and design are, unlike previous versions, both usable and performant even for the largest TAP services.

  7. Application of China's National Forest Continuous Inventory Database

    Xie, Xiaokui; Wang, Qingli; Dai, Limin; Su, Dongkai; Wang, Xinchuang; Qi, Guang; Ye, Yujing


    The maintenance of a timely, reliable and accurate spatial database on current forest ecosystem conditions and changes is essential to characterize and assess forest resources and support sustainable forest management. Information for such a database can be obtained only through a continuous forest inventory. The National Forest Continuous Inventory (NFCI) is the first level of China's three-tiered inventory system. The NFCI is administered by the State Forestry Administration; data are acquired by five inventory institutions around the country. Several important components of the database include land type, forest classification and ageclass/ age-group. The NFCI database in China is constructed based on 5-year inventory periods, resulting in some of the data not being timely when reports are issued. To address this problem, a forest growth simulation model has been developed to update the database for years between the periodic inventories. In order to aid in forest plan design and management, a three-dimensional virtual reality system of forest landscapes for selected units in the database (compartment or sub-compartment) has also been developed based on Virtual Reality Modeling Language. In addition, a transparent internet publishing system for a spatial database based on open source WebGIS (UMN Map Server) has been designed and utilized to enhance public understanding and encourage free participation of interested parties in the development, implementation, and planning of sustainable forest management.

    Kochanov, Roman V.; Hill, Christian; Wcislo, Piotr; Gordon, Iouli E.; Rothman, Laurence S.; Wilzewski, Jonas


    A HITRAN Application Programing Interface (HAPI) has been developed to allow users on their local machines much more flexibility and power. HAPI is a programming interface for the main data-searching capabilities of the new "HITRANonline" web service ( It provides the possibility to query spectroscopic data from the HITRAN database in a flexible manner using either functions or query language. Some of the prominent current features of HAPI are: a) Downloading line-by-line data from the HITRANonline site to a local machine b) Filtering and processing the data in SQL-like fashion c) Conventional Python structures (lists, tuples, and dictionaries) for representing spectroscopic data d) Possibility to use a large set of third-party Python libraries to work with the data e) Python implementation of the HT lineshape which can be reduced to a number of conventional line profiles f) Python implementation of total internal partition sums (TIPS-2011) for spectra simulations g) High-resolution spectra calculation accounting for pressure, temperature and optical path length h) Providing instrumental functions to simulate experimental spectra i) Possibility to extend HAPI's functionality by custom line profiles, partitions sums and instrumental functions Currently the API is a module written in Python and uses Numpy library providing fast array operations. The API is designed to deal with data in multiple formats such as ASCII, CSV, HDF5 and XSAMS.

  12. CORAL Server and CORAL Server Proxy: Scalable Access to Relational Databases from CORAL Applications

    Valassi, A; Kalkhof, A; Salnikov, A; Wache, M


    The CORAL software is widely used at CERN for accessing the data stored by the LHC experiments using relational database technologies. CORAL provides a C++ abstraction layer that supports data persistency for several backends and deployment models, including local access to SQLite files, direct client access to Oracle and MySQL servers, and read-only access to Oracle through the FroNTier web server and cache. Two new components have recently been added to CORAL to implement a model involving a middle tier "CORAL server" deployed close to the database and a tree of "CORAL server proxy" instances, with data caching and multiplexing functionalities, deployed close to the client. The new components are meant to provide advantages for read-only and read-write data access, in both offline and online use cases, in the areas of scalability and performance (multiplexing for several incoming connections, optional data caching) and security (authentication via proxy certificates). A first implementation of the two new c...

  14. A Two-folded Impact Analysis of Schema Changes on Database Applications

    Spyridon K.Gardikiotis; Nicos Malevris


    Database applications are becoming increasingly popular, mainly due to the advanced data management facilities that the underlying database management system offers compared against traditional legacy software applications. The interaction, however, of such applications with the database system introduces a number of issues, among which, this paper addresses the impact analysis of the changes performed at the database schema level. Our motivation is to provide the software engineers of database applications with automated methods that facilitate major maintenance tasks, such as source code corrections and regression testing, which should be triggered by the occurrence of such changes. The presented impact analysis is thus two-folded: the impact is analysed in terms of both the affected source code statements and the affected test suites concerning the testing of these applications. To achieve the former objective, a program slicing technique is employed, which is based on an extended version of the program dependency graph. The latter objective requires the analysis of test suites generated for database applications, which is accomplished by employing testing techniques tailored for this type of applications. Utilising both the slicing and the testing techniques enhances program comprehension of database applications, while also supporting the development of a number of practical metrics regarding their maintainability against schema changes. To evaluate the feasibility and effectiveness of the presented techniques and metrics, a software tool, called DATA, has been implemented. The experimental results from its usage on the TPC-C case study are reported and analysed.

  18. The Application of an Anatomical Database for Fetal Congenital Heart Disease

    Li Yang; Qiu-Yan Pei; Yun-Tao Li; Zhen-Juan Yang


    Background:Fetal congenital heart anomalies are the most common congenital anomalies in live births.Fetal echocardiography (FECG) is the only prenatal diagnostic approach used to detect fetal congenital heart disease (CHD).FECG is not widely used,and the antenatal diagnosis rate of CHD varies considerably.Thus,mastering the anatomical characteristics of different kinds of CHD is critical for ultrasound physicians to improve FECG technology.The aim of this study is to investigate the applications of a fetal CHD anatomic database in FECG teaching and training program.Methods:We evaluated 60 transverse section databases including 27 types of fetal CHD built in the Prenatal Diagnosis Center in Peking University People's Hospital.Each original database contained 400-700 cross-sectional digital images with a resolution of 3744 pixels × 5616 pixels.We imported the database into Amira 5.3.1 (Australia Visage Imaging Company,Australia) three-dimensional (3D) software.The database functions use a series of 3D software visual operations.The features of the fetal CHD anatomical database were analyzed to determine its applications in FECG continuing education and training.Results:The database was rebuilt using the 3D software.The original and rebuilt databases can be displayed dynamically,continuously,and synchronically and can be rotated at arbitrary angles.The sections from the dynamic displays and rotating angles are consistent with the sections in FECG.The database successfully reproduced the anatomic structures and spatial relationship features of different fetal CHDs.We established a fetal CHD anatomy training database and a standardized training database for FECG.Ultrasound physicians and students can learn the anatomical features of fetal CHD and FECG through either centralized training or distance education.Conclusions:The database of fetal CHD successfully reproduced the anatomic structures and spatial relationship of different kinds of fetal CHD.This database can be

  19. HTML thin client and transactions

    Touchette, J F


    When writing applications for thin clients such as Web browsers, you face several challenges that do not exist with fat-client applications written in Visual Basic, Delphi, or Java. For one thing, your development tools do not include facilities for automatically building reliable, nonrepeatable transactions into applications. Consequently, you must devise your own techniques to prevent users from transmitting duplicate transactions. The author explains how to implement reliable, nonrepeatable transactions using a technique that is applicable to any Java Server Development Kit based architecture. Although the examples presented are based on the IBM WebSphere 2.1 Application Server, they do not make use of any IBM WebSphere extensions. In short, the concepts presented here can be implemented in Perl CGI and ASP scripts, and the sample code has been tested with JDK 1.1.6 and 1.2. (0 refs).

  14. Effective use of Java Data objects in developing database applications. Advantages and disadvantages

    Zilidis, Paschalis.


    Approved for public release; distribution is unlimited Currently, the most common approach in developing database applications is to use an object-oriented language for the frontend module and a relational database for the backend datastore. The major disadvantage of this approach is the well-known "impedance mismatch" in which some form of mapping is required to connect the objects in the frontend and the relational tuples in the backend. Java Data Objects (JDO) technology is recently pro...

  15. Discovering Knowledge from AIS Database for Application in VTS

    Tsou, Ming-Cheng

    The widespread use of the Automatic Identification System (AIS) has had a significant impact on maritime technology. AIS enables the Vessel Traffic Service (VTS) not only to offer commonly known functions such as identification, tracking and monitoring of vessels, but also to provide rich real-time information that is useful for marine traffic investigation, statistical analysis and theoretical research. However, due to the rapid accumulation of AIS observation data, the VTS platform is often unable quickly and effectively to absorb and analyze it. Traditional observation and analysis methods are becoming less suitable for the modern AIS generation of VTS. In view of this, we applied the same data mining technique used for business intelligence discovery (in Customer Relation Management (CRM) business marketing) to the analysis of AIS observation data. This recasts the marine traffic problem as a business-marketing problem and integrates technologies such as Geographic Information Systems (GIS), database management systems, data warehousing and data mining to facilitate the discovery of hidden and valuable information in a huge amount of observation data. Consequently, this provides the marine traffic managers with a useful strategic planning resource.

  16. Application of the Trend Filtering Algorithm on the MACHO Database

    Szulagyi, J; Welch, D L


    Due to the strong effect of systematics/trends in variable star observations, we employ the Trend Filtering Algorithm (TFA) on a subset of the MACHO database and search for variable stars. TFA has been applied successfully in planetary transit searches, where weak, short-lasting periodic dimmings are sought in the presence of noise and various systematics (due to, e.g., imperfect flat fielding, crowding, etc). These latter effects introduce colored noise in the photometric time series that can lead to a complete miss of the signal. By using a large number of available photometric time series of a given field, TFA utilizes the fact that the same types of systematics appear in several/many time series of the same field. As a result, we fit each target time series by a (least-square-sense) optimum linear combination of templates and frequency-analyze the residuals. Once a signal is found, we reconstruct the signal by employing the full model, including the signal, systematics and noise. We apply TFA on the brigh...

  20. Data-based considerations for electronic family health history applications.

    Peace, Jane; Valdez, Rupa Sheth; Lutz, Kristin F


    Family health history contains important information about the genetic and environmental factors that contribute to patterns of health and illness in families. Applications for collecting, managing, and analyzing family health history could be improved if their design were informed by an understanding of how consumers think about and report family health history. This article presents a descriptive analysis of themes from family health history interviews that have implications for development, selection, and use of family health history tools. Important themes included ways in which family is defined, including nonbiological family members and pets; ideas about health and disease, including degree of exposure and individual perceptions; and barriers to reporting family health history, including large biological families and uncertainty. Some themes identified (eg, uncertainty) have been recognized previously and continue to be important considerations. Other themes identified, such as perceptions about severity of illness or conditions and causal relationships, are newly recognized and may have implications for nurses and other providers designing, selecting, and using family health history applications.

The modules of alien species database, including classified data input, statistics and analysis, species pictures and distribution maps,and out date input, were approached by Visual 2003 and Microsoft SQL server 2000. The alien species information contains the information of classification, species distinction characteristics, biological characteristics, original area, distribution area, the entering fashion and route, invasion time, invasion reason, interaction with the endemic species, growth state, danger state and spatial information, i.e.distribution map. Based on the above bases, several models including application, checking, modifying, printing, adding and returning models were developed. Furthermore, through the establishment of index tables and index maps, we can also spatially query the data like picture,text and GIS map data. This research established the technological platform of sharing information about scientific resource of alien species in Shandong Province, offering the basis for the dynamic inquiry of alien species, the warning technology of prevention and the fast reaction system. The database application system possessed the principles of good practicability, friendly user interface and convenient usage. It can supply full and accurate information inquiry services of alien species for the users and provide functions of dynamically managing the database for the administrator.

  4. Efficient Mobile Client Caching Supporting Transaction Semantics

    IlYoung Chung


    Full Text Available In mobile client-server database systems, caching of frequently accessed data is an important technique that will reduce the contention on the narrow bandwidth wireless channel. As the server in mobile environments may not have any information about the state of its clients' cache(stateless server, using broadcasting approach to transmit the updated data lists to numerous concurrent mobile clients is an attractive approach. In this paper, a caching policy is proposed to maintain cache consistency for mobile computers. The proposed protocol adopts asynchronous(non-periodic broadcasting as the cache invalidation scheme, and supports transaction semantics in mobile environments. With the asynchronous broadcasting approach, the proposed protocol can improve the throughput by reducing the abortion of transactions with low communication costs. We study the performance of the protocol by means of simulation experiments.

  7. The National Landslide Database and GIS for Great Britain: construction, development, data acquisition, application and communication

    Pennington, Catherine; Dashwood, Claire; Freeborough, Katy


    The National Landslide Database has been developed by the British Geological Survey (BGS) and is the focus for national geohazard research for landslides in Great Britain. The history and structure of the geospatial database and associated Geographical Information System (GIS) are explained, along with the future developments of the database and its applications. The database is the most extensive source of information on landslides in Great Britain with over 16,500 records of landslide events, each documented as fully as possible. Data are gathered through a range of procedures, including: incorporation of other databases; automated trawling of current and historical scientific literature and media reports; new field- and desk-based mapping technologies with digital data capture, and crowd-sourcing information through social media and other online resources. This information is invaluable for the investigation, prevention and mitigation of areas of unstable ground in accordance with Government planning policy guidelines. The national landslide susceptibility map (GeoSure) and a national landslide domain map currently under development rely heavily on the information contained within the landslide database. Assessing susceptibility to landsliding requires knowledge of the distribution of failures and an understanding of causative factors and their spatial distribution, whilst understanding the frequency and types of landsliding present is integral to modelling how rainfall will influence the stability of a region. Communication of landslide data through the Natural Hazard Partnership (NHP) contributes to national hazard mitigation and disaster risk reduction with respect to weather and climate. Daily reports of landslide potential are published by BGS through the NHP and data collected for the National Landslide Database is used widely for the creation of these assessments. The National Landslide Database is freely available via an online GIS and is used by a

  8. Application of the international union of radioecologists soil-to-plant database to Canadian settings

    Over ten years the International Union of Radioecologists (IUR) has amassed a large database on the soil-to-plant transfer of elements. Many of the studies were established using standardized experimental protocols, so that the opportunity for intercomparison is unparalleled among environmental transfer parameter databases. Although most contributors are from Europe, the database includes contributions from Canada and other non-European nations. For Cs, Sr, Co, Pu and Np there are 2035, 920, 782, 679 and 465 records, and there are also some records for Ag, Am, Ce, Cm, 1, La, Mn, Ni, Pb, Po, Ra, Ru, Sb, Tc, Th, U and Zn. An earlier analysis of the database was used to support the statistical distributions of the soil-to-plant transfer parameters applied for the assessment of Canada's nuclear fuel waste concept. The present project re-examines the full database and broadens the application. In many cases, the crops, soils and environmental conditions investigated by the IUR are very applicable to Canadian settings. For several elements, there are sufficient data to develop useful relationships between soil-to-plant transfer and the properties of the soil, although the variation of the transfer values remains large. The resulting estimated parameter values will be useful in many nuclear environmental safety assessments. (author)

  14. Dual diagnosis clients' treatment satisfaction - a systematic review

    Stirling John


    Full Text Available Abstract Background The aim of this systematic review is to synthesize existing evidence about treatment satisfaction among clients with substance misuse and mental health co-morbidity (dual diagnoses, DD. Methods We examined satisfaction with treatment received, variations in satisfaction levels by type of treatment intervention and by diagnosis (i.e. DD clients vs. single diagnosis clients, and the influence of factors other than treatment type on satisfaction. Peer-reviewed studies published in English since 1970 were identified by searching electronic databases using pre-defined search strings. Results Across the 27 studies that met inclusion criteria, high average satisfaction scores were found. In most studies, integrated DD treatment yielded greater client satisfaction than standard treatment without explicit DD focus. In standard treatment without DD focus, DD clients tended to be less satisfied than single diagnosis clients. Whilst the evidence base on client and treatment variables related to satisfaction is small, it suggested client demographics and symptom severity to be unrelated to treatment satisfaction. However, satisfaction tended to be linked to other treatment process and outcome variables. Findings are limited in that many studies had very small sample sizes, did not use validated satisfaction instruments and may not have controlled for potential confounders. A framework for further research in this important area is discussed. Conclusions High satisfaction levels with current treatment provision, especially among those in integrated treatment, should enhance therapeutic optimism among practitioners dealing with DD clients.

  15. An extensible web interface for databases and its application to storing biochemical data

    Angelopoulos, Nicos


    This paper presents a generic web-based database interface implemented in Prolog. We discuss the advantages of the implementation platform and demonstrate the system's applicability in providing access to integrated biochemical data. Our system exploits two libraries of SWI-Prolog to create a schema-transparent interface within a relational setting. As is expected in declarative programming, the interface was written with minimal programming effort due to the high level of the language and its suitability to the task. We highlight two of Prolog's features that are well suited to the task at hand: term representation of structured documents and relational nature of Prolog which facilitates transparent integration of relational databases. Although we developed the system for accessing in-house biochemical and genomic data the interface is generic and provides a number of extensible features. We describe some of these features with references to our research databases. Finally we outline an in-house library that...

Currently the stages under development in ODRA are query optimization. So we present the prior work that is done in ODRA related to Query optimization and we also present a new fusion algorithm of how ODRA can deal with joins based on collections like set, lists, and arrays for query optimization.

  17. The development and application of a thermodynamic database for magnesium alloys

    Shang, Shunli; Zhang, Hui; Ganeshan, Swetha; Liu, Zi-Kui


    The available thermodynamic databases for magnesium alloys are discussed in this paper. Of particular interest are the features of a magnesium database developed by the authors with 19 elements: Mg-Al-Ca-Ce-Cu-Fe-KLa-Li-Mn-Na-Nd-Pr-Si-Sn-Sr-Y-Zn-Zr. Using this database, two applications are presented. One is the phase evolution in AZ61 magnesium alloy including the variations of phase fractions, alloying compositions, and partition coefficients of alloying elements as a function of temperature (or solid fraction). The other is to understand sodium-induced high-temperature embrittlement in the Al-Mg alloy, which is ascribed to the formation of a liquid phase due to the presence of sodium traces.

    Guillaume Tiffon


    Full Text Available Cet article montre que le contact client a beau être ambivalent, dans la mesure où il est à la fois source de contrainte et de reconnaissance, dans certains cas, comme celui des caissières, il constitue avant tout une contrainte, en ce que les clients contrôlent le travail qui s’opère « sous leurs yeux », tandis que, dans d’autres cas, comme celui des kinésithérapeutes, il contribue avant tout à donner du sens au travail et, par là, à susciter l’engagement des travailleurs. L’article souligne ainsi combien la contrainte client revêt des modalités différentes selon la configuration, spatiale et temporelle, dans laquelle se déroule la relation de service, et le différentiel de compétences entre les protagonistes engagés dans cette relation.The client constraint. A comparative analysis of cashiers and physiotherapistsThis article shows that despite the ambivalence of client contact, insofar as it is both a source of constraint and recognition, in some cases, as the ones of cashiers, it isprimarily a constraint: clients control the work that takes place “before their eyes”, whereas in other cases – as in the ones of physiotherapists – it contributes to give meaning to work and, thereby, to arouse the commitment of workers. The article highlights how the client constraint takes on different forms depending on thespatial and temporal configuration where the service relation runs, and the skills differential between the protagonists involved in this relation.El apremio de los clientes. Análisis comparativo entre las cajeras de supermercado y los kinesiterapeutasEn este artículo se demuestra que aunque el contacto con los clientes puede ser percibido como agradable, en realidad en la mayoría de los casos el cliente es percibido como un peso puesto que estos « controlan » visualmente el trabajo de las cajeras mientras que en otras profesiones como es el caso de los kinesiterapeutas la presencia del paciente

Though successful in constructing accurate predictive and classification models, graph kernel functions...

  9. Extending Binary Large Object Support to Open Grid Services Architecture-Data Access and Integration Middleware Client Toolkit

    Kiran K. Patnaik


    Full Text Available Problem statement: OGSA-DAI middleware allows data resources to be federated and accessed via web services on the web or within grids or clouds. It provides a client API for writing programs that access the exposed databases. Migrating existing applications to the new technology and using a new API to access the data of DBMS with BLOB is difficult and discouraging. A JDBC Driver is a much convenient alternative to existing mechanism and provides an extension to OGSA-DAI middleware and allows applications to use databases exposed in a grid through the OGSA-DAI 3.0. However, the driver does not support Binary Large Objects (BLOB. Approach: The driver is enhanced to support BLOB using the OGSA-DAI Client API. It transforms the JDBC calls into an OGSA-DAI workflow request and sends it to the server using Web Services (WS. The client API of OGSA-DAI uses activities that are connected to form a workflow and executed using a pipeline. This workflow mechanism is embedded into the driver. The WS container dispatches the request to the OGSA-DAI middleware for processing and the result is then transformed back to an instance of ResultSet implementation using the OGSA-DAI Client API, before it is returned to the user. Results: Test on handling of BLOBs (images, flash files and videos ranging from size 1 KB to size 2 GB were carried out on Oracle, MySQL and PostgreSQL databases using our enhanced JDBC driver and it performed well. Conclusion: The enhanced JDBC driver now can offer users, with no experience in Grid computing specifically on OGSA-DAI, the possibility to give their applications the ability to access databases exposed on the grid with minimal effort.

  11. Quality control in diagnostic radiology: software (Visual Basic 6) and database applications

    Quality Assurance programme in diagnostic Radiology is being implemented by the Ministry of Health (MoH) in Malaysia. Under this program the performance of an x-ray machine used for diagnostic purpose is tested by using the approved procedure which is commonly known as Quality Control in diagnostic radiology. The quality control or performance tests are carried out b a class H licence holder issued the Atomic Energy Licensing Act 1984. There are a few computer applications (software) that are available in the market which can be used for this purpose. A computer application (software) using Visual Basics 6 and Microsoft Access, is being developed to expedite data handling, analysis and storage as well as report writing of the quality control tests. In this paper important features of the software for quality control tests are explained in brief. A simple database is being established for this purpose which is linked to the software. Problems encountered in the preparation of database are discussed in this paper. A few examples of practical usage of the software and database applications are presented in brief. (Author)

  12. Thermochemistry in BWR. An overview of applications of program codes and databases

    The Swedish work on thermodynamics of metal-water systems relevant to BWR conditions has been ongoing since the 70ies, and at present time a compilation and adaptation of codes and thermodynamic databases are in progress. In the previous work, basic thermodynamic data were compiled for parts of the system Fe-Cr-Ni-Co-Zn-S-H2O at 25-300 °C. Since some thermodynamic information necessary for temperature extrapolations of data up to 300 °C was not published in the earlier works, these data have now been partially recalculated. This applies especially to the parameters of the HKF-model, which are used to extrapolate the thermodynamic data for ionic and neutral aqua species from 25 °C to BWR temperatures. Using the completed data, e.g. the change in standard Gibbs energy (ΔG0) and the equilibrium constant (log K) can be calculated for further applications at BWR/LWR conditions. In addition a computer program is currently being developed at Studsvik for the calculation of equilibrium conductivity in high temperature water. The program is intended for PWR applications, but can also be applied to BWR environment. Data as described above will be added to the database of this program. It will be relatively easy to further develop the program e.g. to calculate Pourbaix diagrams, and these graphs could then be calculated at any temperature. This means that there will be no limitation to the temperatures and total concentrations (usually 10-6 to 10-8 mol/kg) as reported in earlier work. It is also easy to add a function generating ΔG0 and log K values at selected temperatures. One of the fundamentals for this work was also to overview and collect publicly available thermodynamic program codes and databases of relevance for BWR conditions found in open sources. The focus has been on finding already done compilations and reviews, and some 40 codes and 15 databases were found. Codes and data-bases are often integrated and such a package is often developed for applications

    Lulla, Kamlesh; Helfert, Michael; Evans, Cynthia; Wilkinson, M. J.; Pitts, David; Amsbury, David


    The advantages of the astronaut photography during Space Shuttle missions are briefly examined, and the scope and applications of the Space Shuttle earth observations photography database are discussed. The global and multidisciplinary nature of the data base is illustrated by several examples of geologic applications. These include the eruption of Mount Pinatubo (Philippine Islands), heat flow and ice cover on Lake Baikal in Siberia (Russia), and windblown dust in South America. It is noted that hand-held photography from the U.S. Space Shuttle provides unique remotely-sensed data for geologic applications because of the combination of varying perspectives, look angles, and illumination, and changing resolution resulting from different lenses and altitudes.

  3. Image storage, cataloguing and retrieval using a personal computer database software application

    Full text: Interesting images and cases are collected and collated by most nuclear medicine practitioners throughout the world. Changing imaging technology has altered the way in which images may be presented and are reported, with less reliance on 'hard copy' for both reporting and archiving purposes. Digital image generation and storage is rapidly replacing film in both radiological and nuclear medicine practice. A personal computer database based interesting case filing system is described and demonstrated. The digital image storage format allows instant access to both case information (e.g. history and examination, scan report or teaching point) and the relevant images. The database design allows rapid selection of cases and images appropriate to a particular diagnosis, scan type, age or other search criteria. Correlative X-ray, CT, MRI and ultrasound images can also be stored and accessed. The application is in use at The New Children's Hospital as an aid to postgraduate medical education, with new cases being regularly added to the database

  4. Relational database hybrid model, of high performance and storage capacity for nuclear engineering applications

    The objective of this work is to present the relational database, named FALCAO. It was created and implemented to support the storage of the monitored variables in the IEA-R1 research reactor, located in the Instituto de Pesquisas Energeticas e Nucleares, IPEN/CNEN-SP. The data logical model and its direct influence in the integrity of the provided information are carefully considered. The concepts and steps of normalization and de normalization including the entities and relations involved in the logical model are presented. It is also presented the effects of the model rules in the acquisition, loading and availability of the final information, under the performance concept since the acquisition process loads and provides lots of information in small intervals of time. The SACD application, through its functionalities, presents the information stored in the FALCAO database in a practical and optimized form. The implementation of the FALCAO database occurred successfully and its existence leads to a considerably favorable situation. It is now essential to the routine of the researchers involved, not only due to the substantial improvement of the process but also to the reliability associated to it. (author)

  9. Database Access through Java Technologies

    Nicolae MERCIOIU


    Full Text Available As a high level development environment, the Java technologies offer support to the development of distributed applications, independent of the platform, providing a robust set of methods to access the databases, used to create software components on the server side, as well as on the client side. Analyzing the evolution of Java tools to access data, we notice that these tools evolved from simple methods that permitted the queries, the insertion, the update and the deletion of the data to advanced implementations such as distributed transactions, cursors and batch files. The client-server architectures allows through JDBC (the Java Database Connectivity the execution of SQL (Structured Query Language instructions and the manipulation of the results in an independent and consistent manner. The JDBC API (Application Programming Interface creates the level of abstractization needed to allow the call of SQL queries to any DBMS (Database Management System. In JDBC the native driver and the ODBC (Open Database Connectivity-JDBC bridge and the classes and interfaces of the JDBC API will be described. The four steps needed to build a JDBC driven application are presented briefly, emphasizing on the way each step has to be accomplished and the expected results. In each step there are evaluations on the characteristics of the database systems and the way the JDBC programming interface adapts to each one. The data types provided by SQL2 and SQL3 standards are analyzed by comparison with the Java data types, emphasizing on the discrepancies between those and the SQL types, but also the methods that allow the conversion between different types of data through the methods of the ResultSet object. Next, starting from the metadata role and studying the Java programming interfaces that allow the query of result sets, we will describe the advanced features of the data mining with JDBC. As alternative to result sets, the Rowsets add new functionalities that

  10. Development and application of indices using large volcanic databases for a global hazard and risk assessment

    Brown, Sarah; Auker, Melanie; Cottrell, Elizabeth; Delgado Granados, Hugo; Loughlin, Sue; Ortiz Guerrero, Natalie; Sparks, Steve; Vye-Brown, Charlotte; Taskforce, Indices


    monitoring levels around the world; this is designed to be complementary to WOVOdat (the World Organisation of Volcano Observatories: Database of Volcanic Unrest). An index developed from this has been adapted and applied to a global dataset showing that approximately one third of historically active volcanoes have levels of ground-based monitoring that may permit analysis of magma movements and activity forecasts. Some unmonitored volcanoes score highly for both hazard and population risk. The development and application of such indices is dependent on the availability and accessibility of large, systematic, sustainable and compatible databases. These indices help to harmonise approaches and allows first order assessments, highlighting gaps in knowledge and areas where research and investment is recommended.

  12. In-database processing of a large collection of remote sensing data: applications and implementation

    Kikhtenko, Vladimir; Mamash, Elena; Chubarov, Dmitri; Voronina, Polina


    Large archives of remote sensing data are now available to scientists, yet the need to work with individual satellite scenes or product files constrains studies that span a wide temporal range or spatial extent. The resources (storage capacity, computing power and network bandwidth) required for such studies are often beyond the capabilities of individual geoscientists. This problem has been tackled before in remote sensing research and inspired several information systems. Some of them such as NASA Giovanni [1] and Google Earth Engine have already proved their utility for science. Analysis tasks involving large volumes of numerical data are not unique to Earth Sciences. Recent advances in data science are enabled by the development of in-database processing engines that bring processing closer to storage, use declarative query languages to facilitate parallel scalability and provide high-level abstraction of the whole dataset. We build on the idea of bridging the gap between file archives containing remote sensing data and databases by integrating files into relational database as foreign data sources and performing analytical processing inside the database engine. Thereby higher level query language can efficiently address problems of arbitrary size: from accessing the data associated with a specific pixel or a grid cell to complex aggregation over spatial or temporal extents over a large number of individual data files. This approach was implemented using PostgreSQL for a Siberian regional archive of satellite data products holding hundreds of terabytes of measurements from multiple sensors and missions taken over a decade-long span. While preserving the original storage layout and therefore compatibility with existing applications the in-database processing engine provides a toolkit for provisioning remote sensing data in scientific workflows and applications. The use of SQL - a widely used higher level declarative query language - simplifies interoperability

  14. Comprehensive database of human E3 ubiquitin ligases: application to aquaporin-2 regulation.

    Medvar, Barbara; Raghuram, Viswanathan; Pisitkun, Trairak; Sarkar, Abhijit; Knepper, Mark A


    Aquaporin-2 (AQP2) is regulated in part via vasopressin-mediated changes in protein half-life that are in turn dependent on AQP2 ubiquitination. Here we addressed the question, "What E3 ubiquitin ligase is most likely to be responsible for AQP2 ubiquitination?" using large-scale data integration based on Bayes' rule. The first step was to bioinformatically identify all E3 ligase genes coded by the human genome. The 377 E3 ubiquitin ligases identified in the human genome, consisting predominant of HECT, RING, and U-box proteins, have been used to create a publically accessible and downloadable online database ( We also curated a second database of E3 ligase accessory proteins that included BTB domain proteins, cullins, SOCS-box proteins, and F-box proteins. Using Bayes' theorem to integrate information from multiple large-scale proteomic and transcriptomic datasets, we ranked these 377 E3 ligases with respect to their probability of interaction with AQP2. Application of Bayes' rule identified the E3 ligases most likely to interact with AQP2 as (in order of probability): NEDD4 and NEDD4L (tied for first), AMFR, STUB1, ITCH, ZFPL1. Significantly, the two E3 ligases tied for top rank have also been studied extensively in the reductionist literature as regulatory proteins in renal tubule epithelia. The concordance of conclusions from reductionist and systems-level data provides strong motivation for further studies of the roles of NEDD4 and NEDD4L in the regulation of AQP2 protein turnover.

  17. Applications of TsunAWI: Operational scenario database in Indonesia, case studies in Chile

    Rakowsky, Natalja; Harig, Sven; Immerz, Antonia; Androsov, Alexey; Hiller, Wolfgang; Schröter, Jens


    The numerical simulation code TsunAWI was developed in the framework of the German-Indonesian Tsunami Early Warning System (GITEWS). The Numerical simulation of prototypic tsunami scenarios plays a decisive role in the a priori risk assessment for coastal regions and in the early warning process itself. TsunAWI is suited for both tasks. It is based on a finite element discretisation, employs unstructured grids with high resolution along the coast, and includes inundation. This contribution presents two fields of applications. In the Indonesian tsunami early warning system, the existing TsunAWI scenario database covers the Sunda subduction zone from Sumatra to the Lesser Sunda Islands with 715 epicenters and 4500 scenarios. In a collaboration with Geoscience Australia, we support the scientific staff at the Indonesian warning center to extend the data base to the remaining tectonic zones in the Indonesian Archipelago. The extentension started for North Sulawesi, West and East Maluku Islands. For the Hydrographic and Oceanographic Service of the Chilean Navy (SHOA), we calculated a small scenario database of 100 scenarios (sources by Universidad de Chile) for a lightweight decision support system prototype (built by DLR). The earthquake and tsunami events on 1 April 2014 and 16 November 2016 showed the practical use of this approach in comparison to hind casts of these events.

  19. Secure thin client architecture for DICOM image analysis

    Mogatala, Harsha V. R.; Gallet, Jacqueline


    This paper presents a concept of Secure Thin Client (STC) Architecture for Digital Imaging and Communications in Medicine (DICOM) image analysis over Internet. STC Architecture provides in-depth analysis and design of customized reports for DICOM images using drag-and-drop and data warehouse technology. Using a personal computer and a common set of browsing software, STC can be used for analyzing and reporting detailed patient information, type of examinations, date, Computer Tomography (CT) dose index, and other relevant information stored within the images header files as well as in the hospital databases. STC Architecture is three-tier architecture. The First-Tier consists of drag-and-drop web based interface and web server, which provides customized analysis and reporting ability to the users. The Second-Tier consists of an online analytical processing (OLAP) server and database system, which serves fast, real-time, aggregated multi-dimensional data using OLAP technology. The Third-Tier consists of a smart algorithm based software program which extracts DICOM tags from CT images in this particular application, irrespective of CT vendor's, and transfers these tags into a secure database system. This architecture provides Winnipeg Regional Health Authorities (WRHA) with quality indicators for CT examinations in the hospitals. It also provides health care professionals with analytical tool to optimize radiation dose and image quality parameters. The information is provided to the user by way of a secure socket layer (SSL) and role based security criteria over Internet. Although this particular application has been developed for WRHA, this paper also discusses the effort to extend the Architecture to other hospitals in the region. Any DICOM tag from any imaging modality could be tracked with this software.


    Chen, Ting; Rangarajan, Anand; Vemuri, Baba C


    This paper presents a novel classification via aggregated regression algorithm - dubbed CAVIAR - and its application to the OASIS MRI brain image database. The CAVIAR algorithm simultaneously combines a set of weak learners based on the assumption that the weight combination for the final strong hypothesis in CAVIAR depends on both the weak learners and the training data. A regularization scheme using the nearest neighbor method is imposed in the testing stage to avoid overfitting. A closed form solution to the cost function is derived for this algorithm. We use a novel feature - the histogram of the deformation field between the MRI brain scan and the atlas which captures the structural changes in the scan with respect to the atlas brain - and this allows us to automatically discriminate between various classes within OASIS [1] using CAVIAR. We empirically show that CAVIAR significantly increases the performance of the weak classifiers by showcasing the performance of our technique on OASIS. PMID:21151847

    As grids, web services and distributed computing continue to gain popularity in the scientific community, demand for virtual laboratories likewise increases. Today organizations such as the Virtual Laboratory for Earth and Planetary Sciences (VLab) are dedicated to developing web-based portals to perform various simulations remotely while abstracting away details of the underlying computation. Two of the biggest challenges in portal- based computing are fast visualization and smooth interrogation without over taxing clients resources. In response to this challenge, we have expanded on our previous data storage strategy and thick client visualization scheme [1] to develop a client-centric distributed application that utilizes remote visualization of large datasets and makes use of the local graphics processor for improved interactivity. Rather than waste precious client resources for visualization, a combination of 3D graphics and 2D server bitmaps are used to simulate the look and feel of local rendering. Java Web Start and Java Bindings for OpenGL enable install-on- demand functionality as well as low level access to client graphics for all platforms. Powerful visualization services based on VTK and auto-generated by the WATT compiler [2] are accessible through a standard web API. Data is permanently stored on compute nodes while separate visualization nodes fetch data requested by clients, caching it locally to prevent unnecessary transfers. We will demonstrate application capabilities in the context of simulated charge density visualization within the VLab portal. In addition, we will address generalizations of our application to interact with a wider number of WATT services and performance bottlenecks.

  8. Distributed data collection for a database of radiological image interpretations

    Long, L. Rodney; Ostchega, Yechiam; Goh, Gin-Hua; Thoma, George R.


    The National Library of Medicine, in collaboration with the National Center for Health Statistics and the National Institute for Arthritis and Musculoskeletal and Skin Diseases, has built a system for collecting radiological interpretations for a large set of x-ray images acquired as part of the data gathered in the second National Health and Nutrition Examination Survey. This system is capable of delivering across the Internet 5- and 10-megabyte x-ray images to Sun workstations equipped with X Window based 2048 X 2560 image displays, for the purpose of having these images interpreted for the degree of presence of particular osteoarthritic conditions in the cervical and lumbar spines. The collected interpretations can then be stored in a database at the National Library of Medicine, under control of the Illustra DBMS. This system is a client/server database application which integrates (1) distributed server processing of client requests, (2) a customized image transmission method for faster Internet data delivery, (3) distributed client workstations with high resolution displays, image processing functions and an on-line digital atlas, and (4) relational database management of the collected data.
