  1. Building Grid applications using Web Services

    CERN. Geneva

    2004-01-01

    There has been a lot of discussion within the Grid community about the use of Web Services technologies in building large-scale, loosely-coupled, cross-organisation applications. In this talk we are going to explore the principles that govern Service-Oriented Architectures and the promise of Web Services technologies for integrating applications that span administrative domains. We are going to see how existing Web Services specifications and practices could provide the necessary infrastructure for implementing Grid applications. Biography Dr. Savas Parastatidis is a Principal Research Associate at the School of Computing Science, University of Newcastle upon Tyne, UK. Savas is one of the authors of the "Grid Application Framework based on Web Services Specifications and Practices" document that was influential in the convergence between Grid and Web Services and the move away from OGSI (more information can be found at http://www.neresc.ac.uk/ws-gaf). He has done research on runtime support for distributed-m...

  3. gCube Grid services

    Andrade, Pedro

    2008-01-01

    gCube is a service-based framework for eScience applications requiring collaboratory, on-demand, and intensive information processing. It provides to these communities Virtual Research Environments (VREs) to support their activities. gCube is build on top of standard technologies for computational Grids, namely the gLite middleware. The software was produced by the DILIGENT project and will continue to be supported and further developed by the D4Science project. gCube reflects within its name a three-sided interpretation of the Grid vision of resource sharing: sharing of computational resources, sharing of structured data, and sharing of application services. As such, gCube embodies the defining characteristics of computational Grids, data Grids, and virtual data Grids. Precisely, it builds on gLite middleware for managing distributed computations and unstructured data, includes dedicated services for managing data and metadata, provides services for distributed information retrieval, allows the orchestration...

  4. Kibana dashboards for Grid services

    Di Marino, Emiliano

    2015-01-01

    The Platform Service (PS) section of the CERN runs a number of grid services used by thousands of users worldwide. So as to manage these services even more successfully, plan their future, be able to rapidly address problems and easily provide information to the users, it would be useful to have dashboards reporting technical status data. The team of the PS section has put together a monitoring infrastructure based on Kibana/ElasticSearch and found that it can be possible to design dashboards and write collectors rather easily. The main goal of this summer student project is to create more of such dashboards to help PS section to monitor CERN’s grid services.

  5. Monitoring the EGEE/WLCG grid services

    Duarte, A; Nyczyk, P; Retico, A; Vicinanza, D

    2008-01-01

    Grids have the potential to revolutionise computing by providing ubiquitous, on demand access to computational services and resources. They promise to allow for on demand access and composition of computational services provided by multiple independent sources. Grids can also provide unprecedented levels of parallelism for high-performance applications. On the other hand, grid characteristics, such as high heterogeneity, complexity and distribution create many new technical challenges. Among these technical challenges, failure management is a key area that demands much progress. A recent survey revealed that fault diagnosis is still a major problem for grid users. When a failure appears at the user screen, it becomes very difficult for the user to identify whether the problem is in the application, somewhere in the grid middleware, or even lower in the fabric that comprises the grid. In this paper we present a tool able to check if a given grid service works as expected for a given set of users (Virtual Organisation) on the different resources available on a grid. Our solution deals with grid services as single components that should produce an expected output to a pre-defined input, what is quite similar to unit testing. The tool, called Service Availability Monitoring or SAM, is being currently used by several different Virtual Organizations to monitor more than 300 grid sites belonging to the largest grids available today. We also discuss how this tool is being used by some of those VOs and how it is helping in the operation of the EGEE/WLCG grid

  6. Grid accounting service: state and future development

    Levshina, T; Sehgal, C; Bockelman, B; Weitzel, D; Guru, A

    2014-01-01

    During the last decade, large-scale federated distributed infrastructures have been continually developed and expanded. One of the crucial components of a cyber-infrastructure is an accounting service that collects data related to resource utilization and identity of users using resources. The accounting service is important for verifying pledged resource allocation per particular groups and users, providing reports for funding agencies and resource providers, and understanding hardware provisioning requirements. It can also be used for end-to-end troubleshooting as well as billing purposes. In this work we describe Gratia, a federated accounting service jointly developed at Fermilab and Holland Computing Center at University of Nebraska-Lincoln. The Open Science Grid, Fermilab, HCC, and several other institutions have used Gratia in production for several years. The current development activities include expanding Virtual Machines provisioning information, XSEDE allocation usage accounting, and Campus Grids resource utilization. We also identify the direction of future work: improvement and expansion of Cloud accounting, persistent and elastic storage space allocation, and the incorporation of WAN and LAN network metrics.

    2011-12-01

    'Pilot' is a grid job execution service for workflow jobs. The main goal for the service is to automate computations with multiple stages since they can be expressed as simple workflows. Each job is a directed acyclic graph of tasks and each task is an execution of something on a grid resource (or 'computing element'). Tasks may be submitted to any WS-GRAM (Globus Toolkit 4) service. The target resources for the tasks execution are selected by the Pilot service from the set of available resources which match the specific requirements from the task and/or job definition. Some simple conditional execution logic is also provided. The 'Pilot' service is built on the REST concepts and provides a simple API through authenticated HTTPS. This service is deployed and used in production in a Russian national grid project GridNNN.

    2004-01-01

    Geospatial Catalogue Web Service is a vital service for sharing and interoperating volumes of distributed heterogeneous geospatial resources, such as data, services, applications, and their replicas over the web. Based on the Grid technology and the Open Geospatial Consortium (0GC) s Catalogue Service - Web Information Model, this paper proposes a new information model for Geospatial Catalogue Web Service, named as GCWS which can securely provides Grid-based publishing, managing and querying geospatial data and services, and the transparent access to the replica data and related services under the Grid environment. This information model integrates the information model of the Grid Replica Location Service (RLS)/Monitoring & Discovery Service (MDS) with the information model of OGC Catalogue Service (CSW), and refers to the geospatial data metadata standards from IS0 19115, FGDC and NASA EOS Core System and service metadata standards from IS0 191 19 to extend itself for expressing geospatial resources. Using GCWS, any valid geospatial user, who belongs to an authorized Virtual Organization (VO), can securely publish and manage geospatial resources, especially query on-demand data in the virtual community and get back it through the data-related services which provide functions such as subsetting, reformatting, reprojection etc. This work facilitates the geospatial resources sharing and interoperating under the Grid environment, and implements geospatial resources Grid enabled and Grid technologies geospatial enabled. It 2!so makes researcher to focus on science, 2nd not cn issues with computing ability, data locztic, processir,g and management. GCWS also is a key component for workflow-based virtual geospatial data producing.

  12. Grid production with the ATLAS Event Service

    Benjamin, Douglas; The ATLAS collaboration

    2018-01-01

    ATLAS has developed and previously presented a new computing architecture, the Event Service, that allows real time delivery of fine grained workloads which process dispatched events (or event ranges) and immediately streams outputs. The principal aim was to profit from opportunistic resources such as commercial cloud, supercomputing, and volunteer computing, and otherwise unused cycles on clusters and grids. During the development and deployment phase, its utility also on the grid and conventional clusters for the exploitation of otherwise unused cycles became apparent. Here we describe our experience commissioning the Event Service on the grid in the ATLAS production system. We study the performance compared with standard simulation production. We describe the integration with the ATLAS data management system to ensure scalability and compatibility with object stores. Finally, we outline the remaining steps towards a fully commissioned system.

  13. Service Oriented Gridded Atmospheric Radiances (SOAR)

    Halem, M.; Goldberg, M. D.; Tilmes, C.; Zhou, L.; Shen, S.; Yesha, Y.

    2005-12-01

    We are developing a scalable web service tool that can provide complex griding services on-demand for atmospheric radiance data sets from multiple temperature and moisture sounding sensors on the NASA and NOAA polar orbiting satellites collected over the past three decades. This server-to-server middle ware tool will provide the framework for transforming user requests for an arbitrary spatial/temporal/spectral gridded radiance data set from one or more instruments into an action to invoke a griding process from a set of scientifically validated application programs that have been developed to perform such functions. The invoked web service agents will access, subset, concatenate, convolve, perform statistical and physically based griding operations and present the data as specified level 3 gridded fields for analysis and visualization in multiple formats. Examples of the griding operations consist of spatial-temporal radiance averaging accounting for the field of view instrument response function, first footprint in grid bin, selecting min/max brightness temperatures within a grid element, ratios of channels, filtering, convolving high resolution spectral radiances to match broader band spectral radiances, limb adjustments, calculating variances of radiances falling in grid box and creating visual displays of these fields. The gridded web services tool will support both human input through a WWW GUI as well as a direct computer request through a W3C SOAP/XML web service interface. It will generate regional and global gridded data sets on demand. A second effort will demonstrate the ability to locate, access, subset and grid radiance data for any time period and resolution from remote archives of NOAA and NASA data. The system will queue the work flow requests, stage processing and delivery of arbitrary gridded data sets in a data base and notify the users when the request is completed. This tool will greatly expand satellite sounding data utilization by

  17. AstroGrid: AstroGrid: Powering the virtual universe

    Walton, N. A.

    2002-02-01

    Nic Walton describes a programme to break down wavelength barriers and empower astronomers, as well as making full use of astronomical archives. The full potential of the data from the major new observational facilities (e.g. VISTA) available to the community will only be realized if inclusive, rich, data access and manipulation mechanisms are provided. Astronomical endeavour will be further leveraged if these mechanisms enable ``science-driven'' research programmes benefiting from access to multiple data sources. I describe here the reasons and resources behind AstroGrid.

    This paper presents the feasibility and economics of using fuel cell backup power systems in telecommunication cell towers to provide grid services (e.g., ancillary services, demand response). The fuel cells are able to provide power for the cell tower during emergency conditions. This study evaluates the strategic integration of clean, efficient, and reliable fuel cell systems with the grid for improved economic benefits. The backup systems have potential as enhanced capability through information exchanges with the power grid to add value as grid services that depend on location and time. The economic analysis has been focused on the potential revenue for distributed telecommunications fuel cell backup units to provide value-added power supply. This paper shows case studies on current fuel cell backup power locations and regional grid service programs. The grid service benefits and system configurations for different operation modes provide opportunities for expanding backup fuel cell applications responsive to grid needs.

  3. Electric vehicle utilization for ancillary grid services

    Aziz, Muhammad

    2018-02-01

    Electric vehicle has been developed through several decades as transportation mean, without paying sufficient attention of its utilization for other purposes. Recently, the utilization of electric vehicle to support the grid electricity has been proposed and studied intensively. This utilization covers several possible services including electricity storage, spinning reserve, frequency and voltage regulation, and emergency energy supply. This study focuses on theoretical and experimental analysis of utilization of electric vehicles and their used batteries to support a small-scale energy management system. Charging rate of electric vehicle under different ambient temperature (seasonal condition) is initially analyzed to measure the correlation of charging rate, charging time, and state-of-charge. It is confirmed that charging under warmer condition (such as in summer or warmer region) shows higher charging rate than one in colder condition, therefore, shorter charging time can be achieved. In addition, in the demonstration test, each five electric vehicles and used batteries from the same electric vehicles are employed and controlled to support the electricity of the office building. The performance of the system is evaluated throughout a year to measure the load leveling effect during peak-load time. The results show that the targeted peak-load can be shaved well under certain calculated peak-shaving threshold. The finding confirms that the utilization of electric vehicle for supporting the electricity of grid or certain energy management system is feasible and deployable in the future.

    The trend in large-scale scientific data analysis is to exploit compute, storage and other resources located at multiple sites, and to make those resources accessible to the scientist as if they were a single, coherent system. Web technologies driven by the huge and rapidly growing electronic commerce industry provide valuable components to speed the deployment of such sophisticated systems. Jefferson Lab, where several hundred terabytes of experimental data are acquired each year, is in the process of developing a web-based distributed system for data analysis and management. The essential aspects of this system are a distributed data grid (site independent access to experiment, simulation and model data) and a distributed batch system, augmented with various supervisory and management capabilities, and integrated using Java and XML-based web services.

    2012-01-01

    Globally distributed research cyberinfrastructures, like the ALICE Grid Services, need to provide traceability and accountability of operations and internal interactions. This document presents a new security architecture for the ALICE Grid Services, allowing to establish non-repudiation with respect to creatorship and ownership of Grid files and jobs. It is based on mutually authenticated and encrypted communication using X.509 Public Key Infrastructure and the Transport Layer Security (TLS) protocol. Introducing certified Grid file entries and signed Grid jobs by implementing a model of Mediated Definite Delegation it allows to establish long-term accountability concerning Grid jobs and files. Initial submissions as well as any alteration of Grid jobs are becoming verifiable and can be traced back to the originator. The architecture has been implemented as a prototype along with the development of a new central Grid middleware, called jAliEn.

    Full Text Available The Information Service is a fundamental component in a grid environment. It has to meet a lot of requirements such as access to static and dynamic information related to grid resources, efficient and secure access to dynamic data, decentralized maintenance, fault tolerance etc., in order to achieve better performance, scalability, security and extensibility. Currently there are two different major approaches. One is based on a directory infrastructure and another one on a novel approach that exploits a relational DBMS. In this paper we present a performance comparison analysis between Grid Resource Information Service (GRIS and Local Dynamic Grid Catalog relational information service (LDGC, providing also information about two projects (iGrid and Grid Relational Catalog in the grid data management area.

    2005-01-01

    The European GEMSS Project is concerned with the creation of medical Grid service prototypes and their evaluation in a secure service-oriented infrastructure for distributed on demand/supercomputing. Key aspects of the GEMSS Grid middleware include negotiable QoS support for time-critical service provision, flexible support for business models, and security at all levels in order to ensure privacy of patient data as well as compliance to EU law. The GEMSS Grid infrastructure is based on a service-oriented architecture and is being built on top of existing standard Grid and Web technologies. The GEMSS infrastructure offers a generic Grid service provision framework that hides the complexity of transforming existing applications into Grid services. For the development of client-side applications or portals, a pluggable component framework has been developed, providing developers with full control over business processes, service discovery, QoS negotiation, and workflow, while keeping their underlying implementation hidden from view. A first version of the GEMSS Grid infrastructure is operational and has been used for the set-up of a Grid test-bed deploying six medical Grid service prototypes including maxillo-facial surgery simulation, neuro-surgery support, radio-surgery planning, inhaled drug-delivery simulation, cardiovascular simulation and advanced image reconstruction. The GEMSS Grid infrastructure is based on standard Web Services technology with an anticipated future transition path towards the OGSA standard proposed by the Global Grid Forum. GEMSS demonstrates that the Grid can be used to provide medical practitioners and researchers with access to advanced simulation and image processing services for improved preoperative planning and near real-time surgical support.

    2010-01-01

    In the last decade Grid Computing Technology, an innovative extension of distributed computing, is becoming an enabler for computing resource sharing among the participants in 'Virtual Organisations' (VO). Although there exist enormous research efforts on grid-based collaboration technologies, most of them are concentrated on large research and business institutions. In this paper we are considering the adoption of Grid Computing Technology in a VO of small to medium Further Education (FE) and Higher-Education (HE) institutions. We will concentrate on the resource sharing among the campuses of The University of Huddersfield in Yorkshire and colleges in Lancashire, UK, enabled by the Grid. Within this context, it is important to focus on standards that support resource and information sharing, toolkits and middleware solutions that would promote Grid adoption among the FE/HE institutions in the Virtual HE organisation.

    Smart grid allows the integration of distributed renewable energy resources into the conventional electricity distribution power grid such that the goals of reduction in power cost and in environment pollution can be met through an intelligent and efficient matching between power generators and power loads. Currently, this rapidly developing infrastructure is not as "smart" as it should be because of the lack of a flexible, scalable, and adaptive structure. As a solution, this work proposes smart grid as a service (SGaaS), which not only allows a smart grid to be composed out of basic services, but also allows power users to choose between different services based on their own requirements. The two important issues of service-level agreements and composition of services are also addressed in this work. Finally, we give the details of how SGaaS can be implemented using a FIPA-compliant JADE multiagent system.

    2006-01-01

    Based on a proposed Web service-based grid architecture, a service grid middleware system called CROWN is designed in this paper. As the two kernel points of the middleware, the overlay-based distributed grid resource management mechanism is proposed, and the policy-based distributed access control mechanism with the capability of automatic negotiation of the access control policy and trust management and negotiation is also discussed in this paper. Experience of CROWN testbed deployment and application development shows that the middleware can support the typical scenarios such as computing-intensive applications, data-intensive applications and mass information processing applications.

  17. The taming of the Grid : virtual application services

    Keahey, K; Motawi, K.

    2004-01-01

    In this report we develop a view of the Grid based on the application service provider (ASP) model. This view enables the user to see the Grid as a collection of application services that can be published, discovered, and accessed in a relatively straightforward manner, hiding much of the complexity involved in using computational Grids and thus making it simpler and more accessible to a wider range of users. However, in order to satisfy the requirements of real-time scientific application clients, we combine the ASP model with representation of quality of service about the execution of services and the results they produce. Specifically, we focus on real-time, deadline-bound execution as the quality of service derived by a client. We describe an architecture implementing these ideas and the role of client and server in the context of the functionality we develop. We also describe preliminary experiments using an equilibrium fitting application for magnetic fusion in our architecture

  18. Styx Grid Services: Lightweight Middleware for Efficient Scientific Workflows

    J.D. Blower

    2006-01-01

    Full Text Available The service-oriented approach to performing distributed scientific research is potentially very powerful but is not yet widely used in many scientific fields. This is partly due to the technical difficulties involved in creating services and workflows and the inefficiency of many workflow systems with regard to handling large datasets. We present the Styx Grid Service, a simple system that wraps command-line programs and allows them to be run over the Internet exactly as if they were local programs. Styx Grid Services are very easy to create and use and can be composed into powerful workflows with simple shell scripts or more sophisticated graphical tools. An important feature of the system is that data can be streamed directly from service to service, significantly increasing the efficiency of workflows that use large data volumes. The status and progress of Styx Grid Services can be monitored asynchronously using a mechanism that places very few demands on firewalls. We show how Styx Grid Services can interoperate with with Web Services and WS-Resources using suitable adapters.

  19. Industrial Demand Management Providing Ancillary Services to the Distribution Grid

    Rahnama, Samira; Green, Torben; Lyhne, Casper

    2017-01-01

    A prominent feature of the future smart grid is the active participation of the consumer side in ancillary service provision. Grid operators procure ancillary services, including regulating power, voltage control, frequency control, and so on, to ensure safe, reliable, and high-quality electricity...... delivery. Consumers' involvement requires new entities and infrastructure. A so-called aggregator has been introduced as a new player to manage the services that are offered by the consumption units. This paper describes an industrial scale experimental setup for evaluating a particular type of aggregator....... The aggregator aims to provide a distribution grid service from industrial thermal loads through a direct control policy. Our specific case studies are a supermarket refrigeration system and an HVac chiller in conjunction with an ice storage, which are virtually connected to the aggregator. Practical results...

  1. LOCATION TRANSPARENT SERVICE WITH IMPROVED AVAILABILITY [LTSIA] FOR GRID

    A. Suthan

    2011-04-01

    Full Text Available Grid Computing provide ample opportunities in many areas. A authorized user should be able to access any data that has been created by him, in the Grid, considering all the factor for security and other vital criteria such as reliability, availability, secure reading and writing of data. The proposed service helps the authorized user to create, modify, view the data that has been created by him or his group, irrespective of whether he is inside the grid environment or he is outside the grid. This service is maintained and moderated by a co-ordinator which takes care of factors of security, other vital criteria and properties of distributed and grid environment. In order to increase the availability of data LTSIA uses a replication algorithm that decides the number of replicas that has to be created and where to store the replicated data. The decisions are made from the information stored in the service table linked with co-ordinator. Elliptic curve crypto Algorithm is used to encrypt data while being transmitted outside the grid. The authorized user can use a unique id assigned to him to decrypt the data or shall use a digital certificate system as a tool to decrypt it.

  2. Grid Service for User-Centric Job

    Lauret, Jerome

    2009-07-31

    The User Centric Monitoring (UCM) project was aimed at developing a toolkit that provides the Virtual Organization (VO) with tools to build systems that serve a rich set of intuitive job and application monitoring information to the VO’s scientists so that they can be more productive. The tools help collect and serve the status and error information through a Web interface. The proposed UCM toolkit is composed of a set of library functions, a database schema, and a Web portal that will collect and filter available job monitoring information from various resources and present it to users in a user-centric view rather than and administrative-centric point of view. The goal is to create a set of tools that can be used to augment grid job scheduling systems, meta-schedulers, applications, and script sets in order to provide the UCM information. The system provides various levels of an application programming interface that is useful through out the Grid environment and at the application level for logging messages, which are combined with the other user-centric monitoring information in a abstracted “data store”. A planned monitoring portal will also dynamically present the information to users in their web browser in a secure manor, which is also easily integrated into any JSR-compliant portal deployment that a VO might employ. The UCM is meant to be flexible and modular in the ways that it can be adopted to give the VO many choices to build a solution that works for them with special attention to the smaller VOs that do not have the resources to implement home-grown solutions.

    2008-01-01

    The present paper highlights the approach used to design and implement a web services based BaBar Monte Carlo (MC) production grid using Globus Toolkit version 4. The grid integrates the resources of two clusters at the University of Victoria, using the ClassAd mechanism provided by the Condor-G metascheduler. Each cluster uses the Portable Batch System (PBS) as its local resource management system (LRMS). Resource brokering is provided by the Condor matchmaking process, whereby the job and resource attributes are expressed as ClassAds. The important features of the grid are automatic registering of resource ClassAds to the central registry, ClassAds extraction from the registry to the metascheduler for matchmaking, and the incorporation of input/output file staging. Web-based monitoring is employed to track the status of grid resources and the jobs for an efficient operation of the grid. The performance of this new grid for BaBar jobs, and the existing Canadian computational grid (GridX1) based on Globus Toolkit version 2 is found to be consistent

  5. ATLAS grid compute cluster with virtualized service nodes

    Mejia, J; Stonjek, S; Kluth, S

    2010-01-01

    The ATLAS Computing Grid consists of several hundred compute clusters distributed around the world as part of the Worldwide LHC Computing Grid (WLCG). The Grid middleware and the ATLAS software which has to be installed on each site, often require a certain Linux distribution and sometimes even specific version thereof. On the other hand, mostly due to maintenance reasons, computer centres install the same operating system and version on all computers. This might lead to problems with the Grid middleware if the local version is different from the one for which it has been developed. At RZG we partly solved this conflict by using virtualization technology for the service nodes. We will present the setup used at RZG and show how it helped to solve the problems described above. In addition we will illustrate the additional advantages gained by the above setup.

  6. AQUAGRID: The subsurface hydrology Grid service of the Sardinian regional Grid infrastructure

    Lecca, G.; Murgia, F.; Maggi, P.; Perias, A.

    2007-01-01

    AQUAGRID is the subsurface hydrology service of the Sardinian regional Grid infrastructure, designed to deliver complex environmental applications via a user-friendly Web portal. The service is oriented towards the needs of water professionals providing them a flexible and powerful tool to solve water resources management problems and aid decision between different remediation options for contaminated soil and groundwater. In this paper, the AQUAGRID application concept and the enabling technologies are illustrated. The heart of the service is the CODESA-3D hydrogeological model to simulate complex and large groundwater flow and contaminant transport problems. The relevant experience gained from the porting of the CODESA-3D application on the EGEE infrastructure, via the GILDA test bed (https://gilda.ct.infn.it), has contributed to the service prototype. AQUAGRID is built on top of compute-Grid technologies by means of the EnginFrame Grid portal. The portal enables the interaction with the underlying Grid infrastructure and manages the computational requirements of the whole application system. Data management, distribution and visualization mechanisms are based on the tools provided by the DatacroSSing Decision Support System (http://datacrossing.crs4.it). The DSS, built on top of the SRB data-Grid middleware, is based on Web-GIS and relational database technologies. The resulting production environment allows the end-user to visualize and interact with the results of the performed analyses, using graphs, annotated maps and 3D objects. Such a set of graphical widgets increases enormously the number of AQUAGRID potential users because it does not require any specific expertise of the physical model and technological background to be understood.

  7. Software, component, and service deployment in computational Grids

    von Laszewski, G.; Blau, E.; Bletzinger, M.; Gawor, J.; Lane, P.; Martin, S.; Russell, M.

    2002-01-01

    Grids comprise an infrastructure that enables scientists to use a diverse set of distributed remote services and resources as part of complex scientific problem-solving processes. We analyze some of the challenges involved in deploying software and components transparently in Grids. We report on three practical solutions used by the Globus Project. Lessons learned from this experience lead us to believe that it is necessary to support a variety of software and component deployment strategies. These strategies are based on the hosting environment

  8. CERN database services for the LHC computing grid

    Girone, M [CERN IT Department, CH-1211 Geneva 23 (Switzerland)], E-mail: maria.girone@cern.ch

    2008-07-15

    Physics meta-data stored in relational databases play a crucial role in the Large Hadron Collider (LHC) experiments and also in the operation of the Worldwide LHC Computing Grid (WLCG) services. A large proportion of non-event data such as detector conditions, calibration, geometry and production bookkeeping relies heavily on databases. Also, the core Grid services that catalogue and distribute LHC data cannot operate without a reliable database infrastructure at CERN and elsewhere. The Physics Services and Support group at CERN provides database services for the physics community. With an installed base of several TB-sized database clusters, the service is designed to accommodate growth for data processing generated by the LHC experiments and LCG services. During the last year, the physics database services went through a major preparation phase for LHC start-up and are now fully based on Oracle clusters on Intel/Linux. Over 100 database server nodes are deployed today in some 15 clusters serving almost 2 million database sessions per week. This paper will detail the architecture currently deployed in production and the results achieved in the areas of high availability, consolidation and scalability. Service evolution plans for the LHC start-up will also be discussed.

    The Globus information service wasn't working well. There were many updates of data from Globus daemons which saturated the single server and users couldn't retrieve information. We created a second server for NASA and Alliance. Things were great on that server, but a bit slow on the other server. We needed to know exactly how the information service was being used. What were the best servers and configurations? This viewgraph presentation gives an overview of the evaluation of alternative designs for a Grid Information Service. Details are given on the workload characterization, methodology used, and the performance evaluation.

    2013-03-01

    Full Text Available The broad use ofWireless Sensor Networks (WSN in various fields have resulted in growing demand for advanced data collection and querying mechanisms embedded in the sensor node. Sensor Web Services (SWS have recently emerged as a promising tool to enable external machines to have access to the information collected by public sensor webs. Machine-to-machine interactions or wireless sensor and actor networks can take advantage of this platform-independent technology to develop diverse smart grid applications. In this survey, we first briefly present the state of the art in SWS technology by describing the techniques for customizing web services to fit the sensor node capabilities such as customizing the WSDL file, compressing XML documents and redesigning TCP protocol. Then, we survey the studies that have utilized the SWS technology in smart grid applications. These studies have shown that SWS provide energy management capabilities to the consumers and the utilities, and they are well suited for smart grid integrated smart home solutions.

    The paper considers grid computing systems in which the resource management systems (RMS) can divide service tasks into execution blocks (EBs) and send these blocks to different resources. In order to provide a desired level of service reliability the RMS can assign the same blocks to several independent resources for parallel execution. The data security is a crucial issue in distributed computing that affects the execution policy. By the optimal service task partition into the EBs and their distribution among resources, one can achieve the greatest possible service reliability and/or expected performance subject to data security constraints. The paper suggests an algorithm for solving this optimization problem. The algorithm is based on the universal generating function technique and on the evolutionary optimization approach. Illustrative examples are presented. - Highlights: > Grid service with star topology is considered. > An algorithm for evaluating service reliability and data security is presented. > A tradeoff between the service reliability and data security is analyzed. > A procedure for optimal service task partition and distribution is suggested.

    2017-04-01

    Cloud, Grid and High Performance Computing have changed the accessibility and availability of computing resources for Earth Science research communities, specially for Climate community. These paradigms are modifying the way how climate applications are being executed. By using these technologies the number, variety and complexity of experiments and resources are increasing substantially. But, although computational capacity is increasing, traditional applications and tools used by the community are not good enough to manage this large volume and variety of experiments and computing resources. In this contribution, we evaluate the challenges to run climate simulations and services on Grid, Cloud and HPC infrestructures and how to tackle them. The Grid and Cloud infrastructures provided by EGI's VOs ( esr , earth.vo.ibergrid and fedcloud.egi.eu) will be evaluated, as well as HPC resources from PRACE infrastructure and institutional clusters. To solve those challenges, solutions using DRM4G framework will be shown. DRM4G provides a good framework to manage big volume and variety of computing resources for climate experiments. This work has been supported by the Spanish National R&D Plan under projects WRF4G (CGL2011-28864), INSIGNIA (CGL2016-79210-R) and MULTI-SDM (CGL2015-66583-R) ; the IS-ENES2 project from the 7FP of the European Commission (grant agreement no. 312979); the European Regional Development Fund—ERDF and the Programa de Personal Investigador en Formación Predoctoral from Universidad de Cantabria and Government of Cantabria.

    To process the vast amount of data from high energy physics experiments, physicists rely on Computational and Data Grids; yet, the distribution, installation, and updating of a myriad of different versions of different programs over the Grid environment is complicated, time-consuming, and error-prone. Our Grid Software Installation Management Framework (GSIMF) is a set of Grid Services that has been developed for managing versioned and interdependent software applications and file-based databases over the Grid infrastructure. This set of Grid services provide a mechanism to install software packages on distributed Grid computing elements, thus automating the software and database installation management process on behalf of the users. This enables users to remotely install programs and tap into the computing power provided by Grids

    GRIF is a distributed Tiers 2 centre, made of 6 different centres in the Paris region, and serving many VOs. The sub-sites are connected with 10 Gbps private network and share tools for central management. One of the sub-sites, GRIF-IRFU held and maintained in the CEA- Saclay centre, moved a year ago, to a configuration management using Puppet. Thanks to the versatility of Puppet/Foreman automation, the GRIF-IRFU site maintains usual grid services, with, among them: a CREAM-CE with a TORQUE+Maui (running a batch with more than 5000 jobs slots), a DPM storage of more than 2 PB, a Nagios monitoring essentially based on check_mk, as well as centralized services for the French NGI, like the accounting, or the argus central suspension system. We report on the actual functionalities of Puppet and present the last tests and evolutions including a monitoring with Graphite, a HT-condor multicore batch accessed with an ARC-CE and a CEPH storage file system.

  6. Availability measurement of grid services from the perspective of a scientific computing centre

    Marten, H; Koenig, T

    2011-01-01

    The Karlsruhe Institute of Technology (KIT) is the merger of Forschungszentrum Karlsruhe and the Technical University Karlsruhe. The Steinbuch Centre for Computing (SCC) was one of the first new organizational units of KIT, combining the former Institute for Scientific Computing of Forschungszentrum Karlsruhe and the Computing Centre of the University. IT service management according to the worldwide de-facto-standard 'IT Infrastructure Library (ITIL)' was chosen by SCC as a strategic element to support the merging of the two existing computing centres located at a distance of about 10 km. The availability and reliability of IT services directly influence the customer satisfaction as well as the reputation of the service provider, and unscheduled loss of availability due to hardware or software failures may even result in severe consequences like data loss. Fault tolerant and error correcting design features are reducing the risk of IT component failures and help to improve the delivered availability. The ITIL process controlling the respective design is called Availability Management. This paper discusses Availability Management regarding grid services delivered to WLCG and provides a few elementary guidelines for availability measurements and calculations of services consisting of arbitrary numbers of components.

  8. ReSS: Resource Selection Service for National and Campus Grid Infrastructure

    Mhashilkar, Parag; Garzoglio, Gabriele; Levshina, Tanya; Timm, Steve

    2010-01-01

    The Open Science Grid (OSG) offers access to around hundred Compute elements (CE) and storage elements (SE) via standard Grid interfaces. The Resource Selection Service (ReSS) is a push-based workload management system that is integrated with the OSG information systems and resources. ReSS integrates standard Grid tools such as Condor, as a brokering service and the gLite CEMon, for gathering and publishing resource information in GLUE Schema format. ReSS is used in OSG by Virtual Organizations (VO) such as Dark Energy Survey (DES), DZero and Engagement VO. ReSS is also used as a Resource Selection Service for Campus Grids, such as FermiGrid. VOs use ReSS to automate the resource selection in their workload management system to run jobs over the grid. In the past year, the system has been enhanced to enable publication and selection of storage resources and of any special software or software libraries (like MPI libraries) installed at computing resources. In this paper, we discuss the Resource Selection Service, its typical usage on the two scales of a National Cyber Infrastructure Grid, such as OSG, and of a campus Grid, such as FermiGrid.

    Mhashilkar, Parag; Garzoglio, Gabriele; Levshina, Tanya; Timm, Steve

    2009-01-01

    The Open Science Grid (OSG) offers access to around hundred Compute elements (CE) and storage elements (SE) via standard Grid interfaces. The Resource Selection Service (ReSS) is a push-based workload management system that is integrated with the OSG information systems and resources. ReSS integrates standard Grid tools such as Condor, as a brokering service and the gLite CEMon, for gathering and publishing resource information in GLUE Schema format. ReSS is used in OSG by Virtual Organizations (VO) such as Dark Energy Survey (DES), DZero and Engagement VO. ReSS is also used as a Resource Selection Service for Campus Grids, such as FermiGrid. VOs use ReSS to automate the resource selection in their workload management system to run jobs over the grid. In the past year, the system has been enhanced to enable publication and selection of storage resources and of any special software or software libraries (like MPI libraries) installed at computing resources. In this paper, we discuss the Resource Selection Service, its typical usage on the two scales of a National Cyber Infrastructure Grid, such as OSG, and of a campus Grid, such as FermiGrid.

    Disclosed herein are representative embodiments of methods, apparatus, and systems for charging and discharging an energy storage device connected to an electrical power distribution system. In one exemplary embodiment, a controller monitors electrical characteristics of an electrical power distribution system and provides an output to a bi-directional charger causing the charger to charge or discharge an energy storage device (e.g., a battery in a plug-in hybrid electric vehicle (PHEV)). The controller can help stabilize the electrical power distribution system by increasing the charging rate when there is excess power in the electrical power distribution system (e.g., when the frequency of an AC power grid exceeds an average value), or by discharging power from the energy storage device to stabilize the grid when there is a shortage of power in the electrical power distribution system (e.g., when the frequency of an AC power grid is below an average value).

    2018-01-01

    Applying institutional theory to look at the Program 74 (a universal service policy) in Vietnam, this paper concludes that the Vietnamese universal service policy was strongly affected by formal institutional factors (the international agreements and the directives of the Communist Party of Vietnam...... - CPV), in which the international agreements played a leading role and the CPV’s directives played a guarantee role. The formulation and implementation of the universal service policy in Vietnam were mainly concentrated on action at levels 2 and 3 (formal and informal institutional arrangement......, and formal institutional environment). The paper recommends that nations favouring a top-down approach not based on a market-oriented regime should deregulate and emphasize the role of provincial governments as well as encourage private sectors/social organizations and rural users to be more involved...

  6. Potential For Plug-In Electric Vehicles To Provide Grid Support Services

    Dias, F. G.; Luo, Y.; Mohanpurkar, M.; Hovsapian, R.; Scoffield, D.

    2017-04-01

    Since the modern-day introduction of plug-in electric vehicles (PEVs), scientists have proposed leveraging PEV battery packs as distributed energy resources for the electric grid. PEV charging can be controlled not only to provide energy for transportation but also to provide grid services and to facilitate the integration of renewable energy generation. With renewable generation increasing at an unprecedented rate, most of which is non-dispatchable and intermittent, the concept of using PEVs as controllable loads is appealing to electric utilities. This additional functionality could also provide value to PEV owners and drive PEV adoption. It has been widely proposed that PEVs can provide valuable grid services, such as load shifting to provide voltage regulation. The objective this work is to address the degree to which PEVs can provide grid services and mutually benefit the electric utilities, PEV owners, and auto manufacturers.

  7. The GridEcon Platform: A Business Scenario Testbed for Commercial Cloud Services

    Risch, Marcel; Altmann, Jörn; Guo, Li; Fleming, Alan; Courcoubetis, Costas

    Within this paper, we present the GridEcon Platform, a testbed for designing and evaluating economics-aware services in a commercial Cloud computing setting. The Platform is based on the idea that the exact working of such services is difficult to predict in the context of a market and, therefore, an environment for evaluating its behavior in an emulated market is needed. To identify the components of the GridEcon Platform, a number of economics-aware services and their interactions have been envisioned. The two most important components of the platform are the Marketplace and the Workflow Engine. The Workflow Engine allows the simple composition of a market environment by describing the service interactions between economics-aware services. The Marketplace allows trading goods using different market mechanisms. The capabilities of these components of the GridEcon Platform in conjunction with the economics-aware services are described in this paper in detail. The validation of an implemented market mechanism and a capacity planning service using the GridEcon Platform also demonstrated the usefulness of the GridEcon Platform.

    implementing real load control programs. The promise of autonomous, Grid Friendly™ response by smart appliances in the form of under-frequency load shedding was demonstrated in the GridWise Olympic Peninsula Demonstration in 2006. Each controller monitored the power grid voltage signal and requested that electrical load be shed by its appliance whenever electric power-grid frequency fell below 59.95 Hz. The controllers and their appliances responded reliably to each shallow under-frequency event, which was an average of one event per day and shed their loads for the durations of these events. Another objective of this project was to perform extensive simulation studies to investigate the impact of a population of Grid Friendly™ Appliances (GFAs) on the bulk power system frequency stability. The GFAs considered in this report are represented as demonstration units with water heaters individually modeled.

  13. Grid Technology as a Cyberinfrastructure for Delivering High-End Services to the Earth and Space Science Community

    Hinke, Thomas H.

    2004-01-01

    Grid technology consists of middleware that permits distributed computations, data and sensors to be seamlessly integrated into a secure, single-sign-on processing environment. In &is environment, a user has to identify and authenticate himself once to the grid middleware, and then can utilize any of the distributed resources to which he has been,panted access. Grid technology allows resources that exist in enterprises that are under different administrative control to be securely integrated into a single processing environment The grid community has adopted commercial web services technology as a means for implementing persistent, re-usable grid services that sit on top of the basic distributed processing environment that grids provide. These grid services can then form building blocks for even more complex grid services. Each grid service is characterized using the Web Service Description Language, which provides a description of the interface and how other applications can access it. The emerging Semantic grid work seeks to associates sufficient semantic information with each grid service such that applications wii1 he able to automatically select, compose and if necessary substitute available equivalent services in order to assemble collections of services that are most appropriate for a particular application. Grid technology has been used to provide limited support to various Earth and space science applications. Looking to the future, this emerging grid service technology can provide a cyberinfrastructures for both the Earth and space science communities. Groups within these communities could transform those applications that have community-wide applicability into persistent grid services that are made widely available to their respective communities. In concert with grid-enabled data archives, users could easily create complex workflows that extract desired data from one or more archives and process it though an appropriate set of widely distributed grid

    Martinenas, Sergejus; Marinelli, Mattia; Andersen, Peter Bach

    2016-01-01

    Replacement of conventional generation by more stochastic renewable generation sources leads to reduction of inertia and controllability in the power system. This introduces the need for more dynamic regulation services. These faster services could potentially be provided by the growing number...... of electric vehicles. EVs are a fast responding energy resource with high availability. This work evaluates and experimentally shows the limits of EV charging controllability with the focus on its suitability for providing ancillary grid services. Three different series produced EVs are tested.......

    2010-01-01

    Future fusion experiments, aiming to demonstrate steady state reactor operation, require physics driven plasma control based on increasingly complex plasma models. A precondition for establishing such control systems is widely automated data analysis, which can provide integration of multiple diagnostic on a large scale. Even high quality online data evaluation, which is essential for the scientific documentation of the experiment, has to be performed automatically due to the huge data sets being recorded in long discharge runs. An automated system that can handle these requirements will have to be built on reusable software components that can be maintained by the domain experts: diagnosticians, theorists, engineers and others. For Wendelstein 7-X a service oriented architecture seems to be appropriate, in which software components can be exposed as services with well defined interface contracts. Although grid computing has up to now been mainly used for remote job execution, a more promising service oriented middleware has emerged from the recent grid specification, the open grid service architecture (OGSA). It is based on stateful web services defined by the web service resource framework (WSRF) standard. In particular, the statefulness of services allows to setup complex models without unnecessary performance losses by frequent transmission of large and complex data sets. At present, the usability of this technology in the W7-X CoDaC context is under evaluation by first service implementations.

  20. Hierarchical Data Replication and Service Monitoring Methods in a Scientific Data Grid

    Weizhong Lu

    2009-04-01

    Full Text Available In a grid and distributed computing environment, data replication is an effective way to improve data accessibility and data accessing efficiency. It is also significant in developing a real-time service monitoring system for a Chinese Scientific Data Grid to guarantee the system stability and data availability. Hierarchical data replication and service monitoring methods are proposed in this paper. The hierarchical data replication method divides the network into different domains and replicates data in local domains. The nodes in a local domain are classified into hierarchies to improve data accessibility according to bandwidth and storage memory space. An extensible agent-based prototype of a hierarchical service monitoring system is presented. The status information of services in the Chinese Scientific Data Grid is collected from the grid nodes based on agent technology and then is transformed into real-time operational pictures for management needs. This paper presents frameworks of the hierarchical data replication and service monitoring methods and gives detailed resolutions. Simulation analyses have demonstrated improved data accessing efficiency and verified the effectiveness of the methods at the same time.

  1. Development of stable Grid service at the next generation system of KEKCC

    Nakamura, T.; Iwai, G.; Matsunaga, H.; Murakami, K.; Sasaki, T.; Suzuki, S.; Takase, W.

    2017-10-01

    A lot of experiments in the field of accelerator based science are actively running at High Energy Accelerator Research Organization (KEK) by using SuperKEKB and J-PARC accelerator in Japan. In these days at KEK, the computing demand from the various experiments for the data processing, analysis, and MC simulation is monotonically increasing. It is not only for the case with high-energy experiments, the computing requirement from the hadron and neutrino experiments and some projects of astro-particle physics is also rapidly increasing due to the very high precision measurement. Under this situation, several projects, Belle II, T2K, ILC and KAGRA experiments supported by KEK are going to utilize Grid computing infrastructure as the main computing resource. The Grid system and services in KEK, which is already in production, are upgraded for the further stable operation at the same time of whole scale hardware replacement of KEK Central Computer System (KEKCC). The next generation system of KEKCC starts the operation from the beginning of September 2016. The basic Grid services e.g. BDII, VOMS, LFC, CREAM computing element and StoRM storage element are made by the more robust hardware configuration. Since the raw data transfer is one of the most important tasks for the KEKCC, two redundant GridFTP servers are adapted to the StoRM service instances with 40 Gbps network bandwidth on the LHCONE routing. These are dedicated to the Belle II raw data transfer to the other sites apart from the servers for the data transfer usage of the other VOs. Additionally, we prepare the redundant configuration for the database oriented services like LFC and AMGA by using LifeKeeper. The LFC servers are made by two read/write servers and two read-only servers for the Belle II experiment, and all of them have an individual database for the purpose of load balancing. The FTS3 service is newly deployed as a service for the Belle II data distribution. The service of CVMFS stratum-0 is

  2. A new service-oriented grid-based method for AIoT application and implementation

    Zou, Yiqin; Quan, Li

    2017-07-01

    The traditional three-layer Internet of things (IoT) model, which includes physical perception layer, information transferring layer and service application layer, cannot express complexity and diversity in agricultural engineering area completely. It is hard to categorize, organize and manage the agricultural things with these three layers. Based on the above requirements, we propose a new service-oriented grid-based method to set up and build the agricultural IoT. Considering the heterogeneous, limitation, transparency and leveling attributes of agricultural things, we propose an abstract model for all agricultural resources. This model is service-oriented and expressed with Open Grid Services Architecture (OGSA). Information and data of agricultural things were described and encapsulated by using XML in this model. Every agricultural engineering application will provide service by enabling one application node in this service-oriented grid. Description of Web Service Resource Framework (WSRF)-based Agricultural Internet of Things (AIoT) and the encapsulation method were also discussed in this paper for resource management in this model.

  6. Application of microgrids in providing ancillary services to the utility grid

    Majzoobi, Alireza; Khodaei, Amin

    2017-01-01

    A microgrid optimal scheduling model is developed in this paper to demonstrate microgrid's capability in offering ancillary services to the utility grid. The application of localized ancillary services is of significant importance to grid operators as the growing proliferation of distributed renewable energy resources, mainly solar generation, is causing major technical challenges in supply-load balance. The proposed microgrid optimal scheduling model coordinates the microgrid net load with the aggregated consumers/prosumers net load in its connected distribution feeder to capture both inter-hour and intra-hour net load variations. In particular, net load variations for three various time resolutions are considered, including hourly ramping, 10-min based load following, and 1-min based frequency regulation. Numerical simulations on a test distribution feeder with one microgrid and several consumers/prosumers indicate the effectiveness of the proposed model and the viability of the microgrid application in supporting grid operation. - Highlights: • Microgrid optimal scheduling for providing ancillary services to the utility grid. • Local management and mitigation of distribution net load variations. • Offering various support services: ramping, load following, frequency regulation. • Proven effectiveness and accuracy in capturing net load variations.

  7. Exploration of potential of Smart Grids at the scale of the University campus in Provence

    2014-09-01

    This study notably aimed at determining how strategies provided by smart grid technologies operate in an existing area where electric equipment and infrastructures are already largely developed, which perspectives of evolution these technologies offer for the power demand curve of the electric power distribution network, and how to assess benefits associated with the implementation of these technologies at the scale of an existing area. After a presentation of various concepts, the report presents a simplified model of the electric power consumption structure for the studied area (a university campus). The next part proposes an assessment of potentials related to smart grid technologies by using six scenarios and by modelling their effect. The different possible strategies are then analysed

  8. User centric monitoring (UCM) information service for the next generation of Grid-enabled scientists

    Alexander, D A; Li, C; Lauret, J; Fine, V

    2008-01-01

    Nuclear and high-energy physicists routinely execute data processing and data analysis jobs on a Grid and need to be able to easily and remotely monitor the execution of these jobs. Existing Grid monitoring tools provide abundant information about the whole system, but are geared towards production jobs and well suited for Grid administrators, while the information tailored towards an individual user is not readily available in a user-friendly and user-centric way. Such User Centric information includes monitoring information such as the status of the submitted job, queue position, time of the start/finish, percentage of being done, error messages, standard output, and reasons for failure. We proposed to develop a framework based on Grid service technology that allows scientists to track and monitor their jobs easily from a user-centric view. The proposed framework aims to be flexible so that it can be applied by any Grid Virtual Organization (VO) with various ways of collecting the user-centric job monitoring information built into the framework. Furthermore, the framework provides a rich and reusable set of methods of presenting the information to the user from within a Web browser and other clients. In this presentation, we will give an architectural overview of the UCM service, show an example implementation in the RHIC/STAR experiment context and discuss limitations and future collaborative work

  9. A Hierarchy of Network Performance Characteristics for Grid Applications and Services

    Lowekamp, B

    2004-07-06

    This document describes a standard set of network characteristics that are useful for Grid applications and services as well as a classification hierarchy for these characteristics. The goal of this work is to identify the various types of network measurements according to the network characteristic they measure and the network entity on which they are taken. This document defines standard terminology to describe those measurements, but it does not attempt to define new standard measurement methodologies or attempt to define the best measurement methodologies to use for grid applications. However, it does attempt to point out the advantages and disadvantages of different measurement methodologies. This document was motivated by the need for the interchange of measurements taken by various systems in the Grid and to develop a common dictionary to facilitate discussions about and specifications for measurement systems. The application of this naming system will facilitate the creation of common schemata for describing network monitoring data in Grid Monitoring and Discovery Services, and thus help to address portability issues between the wide variety of network measurements used between sites of a Grid.

  12. WebGIS based on semantic grid model and web services

    Zhang, WangFei; Yue, CaiRong; Gao, JianGuo

    2009-10-01

    As the combination point of the network technology and GIS technology, WebGIS has got the fast development in recent years. With the restriction of Web and the characteristics of GIS, traditional WebGIS has some prominent problems existing in development. For example, it can't accomplish the interoperability of heterogeneous spatial databases; it can't accomplish the data access of cross-platform. With the appearance of Web Service and Grid technology, there appeared great change in field of WebGIS. Web Service provided an interface which can give information of different site the ability of data sharing and inter communication. The goal of Grid technology was to make the internet to a large and super computer, with this computer we can efficiently implement the overall sharing of computing resources, storage resource, data resource, information resource, knowledge resources and experts resources. But to WebGIS, we only implement the physically connection of data and information and these is far from the enough. Because of the different understanding of the world, following different professional regulations, different policies and different habits, the experts in different field will get different end when they observed the same geographic phenomenon and the semantic heterogeneity produced. Since these there are large differences to the same concept in different field. If we use the WebGIS without considering of the semantic heterogeneity, we will answer the questions users proposed wrongly or we can't answer the questions users proposed. To solve this problem, this paper put forward and experienced an effective method of combing semantic grid and Web Services technology to develop WebGIS. In this paper, we studied the method to construct ontology and the method to combine Grid technology and Web Services and with the detailed analysis of computing characteristics and application model in the distribution of data, we designed the WebGIS query system driven by

    Highlights: • The availability uncertainty of PEVs are modelled using Gaussian mixture model. • Interdependency of stochastic variables are modelled using copula function. • V2G bidding capacity is calculated using Free Pattern search optimization method. • Localization limitation is considered for V2G service potential assessment. • Competitive services for fleet of V2G-enabled PEVs are identified using fuzzy sets. - Abstract: The aim of the paper is to propose an approach for statistical assessment of the potential of plug-in electric vehicles (PEV) for vehicle-to-grid (V2G) ancillary services, where it focuses on PEVs doing daily home-work commuting. In this approach, the possible ancillary services (A/S) for each PEV fleet in terms of its available V2G power (AVP) and flexible intervals are identified. The flexible interval is calculated using a powerful stochastic global optimization technique so-called “Free Pattern Search” (FPS). A probabilistic method is also proposed to quantify the impacts of PEV’s availability uncertainty using the Gaussian mixture model (GMM), and interdependency of stochastic variables on AVP of each fleet thanks to a multivariate modeling with Copula function. Each fleet is analyzed based on its aggregated PEV numbers at different level of distribution grid, in order to satisfy the ancillary services localization limitation. A case study using the proposed approach evaluates the real potential in Niort, a city in west of France. In fact, by using the proposed approach an aggregator can analyze the V2G potential of PEVs under its contract.

  14. ICT Requirements and Challenges for Provision of Grid Services from Renewable Generation Plants

    Shahid, Kamal; Olsen, Rasmus Løvenstein; Petersen, Lennart

    2018-01-01

    The penetration of renewable energy into the electricity supply mix necessitates the traditional power grid to become more resilient, reliable and efficient. One way of ensuring this is to require renewable power plants to have similar regulating properties as conventional power plants...... applications – in terms of data payloads, sampling rates, latency and reliability. Therefore, this paper presents a brief survey on the control and communication architectures for controlling renewable power plants in the future power grid, including the communication network technologies, requirements...... and to coordinate their grid support services (GSS) as well. Among other requirements, the coordination of GSS will highly depend on the communication between renewable plants and system operators’ control rooms, thereby imposing high responsibility on the under lying communication infrastructure. Despite...

    2012-03-01

    Deformable elastic network (DEN) restraints have proved to be a powerful tool for refining structures from low-resolution X-ray crystallographic data sets. Unfortunately, optimal refinement using DEN restraints requires extensive calculations and is often hindered by a lack of access to sufficient computational resources. The DEN web service presented here intends to provide structural biologists with access to resources for running computationally intensive DEN refinements in parallel on the Open Science Grid, the US cyberinfrastructure. Access to the grid is provided through a simple and intuitive web interface integrated into the SBGrid Science Portal. Using this portal, refinements combined with full parameter optimization that would take many thousands of hours on standard computational resources can now be completed in several hours. An example of the successful application of DEN restraints to the human Notch1 transcriptional complex using the grid resource, and summaries of all submitted refinements, are presented as justification.

  17. Adoption of energy-efficient televisions for expanded off-grid electricity service

    Won Young Park

    Full Text Available Even though they dominate the global television (TV market, light-emitting diode backlit liquid crystal display (LED-LCD TVs have received little attention for use with off-grid household-scale renewable energy systems, primarily because of high up-front costs. However, technological advances and price declines mean that these TVs can now provide the same level of electricity service as standard LED-LCD TVs offer but at lower total energy cost. Moreover, LED-LCD TVs are inherently direct-current (DC-powered devices and therefore well suited for use with off-grid solar home systems. We estimate that DC-powered energy-efficient LED-LCD TVs can decrease the retail purchase price of solar home systems by about 25% by allowing use of 50% smaller photovoltaics and battery capacities than would be needed for the same energy system to power a standard LED-LCD TV. We recommend that policies such as awards, bulk procurement, incentives, and energy labels be considered to facilitate the adoption of these energy-efficient TVs in off-grid settings.

  18. Distributor pricing approaches enabled in Smart Grid to differentiate delivery service quality

    Zhongwei Jake Zhang

    2014-12-01

    Full Text Available Industry practitioners who advocate retail competition and Demand-side Participation now look for approaches to link both initiatives through distributor pricing. As distributors incrementally convert more traditional assets into Smart Grid assets, they also need to consider different pricing approaches to recover the investment costs and meet the regulatory business requirements. Small electricity consumers need incentives to take part in these initiatives but their delivery service quality should also be closely guarded. Hence this paper addresses the above needs as a whole and investigates a set of distributor pricing approaches with Smart Grid technologies. Pricing of network and non-network based solutions should follow the incremental basis, such as the long run average incremental cost (LRAIC. The benefit of deferring network investment is calculated and should be passed to consumers as peak pricing rebate. A concept of reliability premium (RP based on load point reliability index is proposed, through which customers can express their preference of service quality and adjust their network tariff payment accordingly. A service delivery model is also proposed to utilize the savings from wholesale market trading to compensate for the downgraded service when loads are controlled. The IEEE 123-node distribution test feeder and the IEEE distribution system for RBTS Bus No. 2 are simulated, and solved using General Algebraic Modeling System (GAMS to demonstrate the proposed distributor pricing approaches in Smart Grid.

  19. Towards a global service registry for the world-wide LHC computing grid

    Field, Laurence; Pradillo, Maria Alandes; Girolamo, Alessandro Di

    2014-01-01

    The World-Wide LHC Computing Grid encompasses a set of heterogeneous information systems; from central portals such as the Open Science Grid's Information Management System and the Grid Operations Centre Database, to the WLCG information system, where the information sources are the Grid services themselves. Providing a consistent view of the information, which involves synchronising all these informations systems, is a challenging activity that has lead the LHC virtual organisations to create their own configuration databases. This experience, whereby each virtual organisation's configuration database interfaces with multiple information systems, has resulted in the duplication of effort, especially relating to the use of manual checks for the handling of inconsistencies. The Global Service Registry aims to address this issue by providing a centralised service that aggregates information from multiple information systems. It shows both information on registered resources (i.e. what should be there) and available resources (i.e. what is there). The main purpose is to simplify the synchronisation of the virtual organisation's own configuration databases, which are used for job submission and data management, through the provision of a single interface for obtaining all the information. By centralising the information, automated consistency and validation checks can be performed to improve the overall quality of information provided. Although internally the GLUE 2.0 information model is used for the purpose of integration, the Global Service Registry in not dependent on any particular information model for ingestion or dissemination. The intention is to allow the virtual organisation's configuration databases to be decoupled from the underlying information systems in a transparent way and hence simplify any possible future migration due to the evolution of those systems. This paper presents the Global Service Registry architecture, its advantages

  1. Grid enablement of OpenGeospatial Web Services: the G-OWS Working Group

    Mazzetti, Paolo

    2010-05-01

    In last decades two main paradigms for resource sharing emerged and reached maturity: the Web and the Grid. They both demonstrate suitable for building Distributed Computing Infrastructures (DCIs) supporting the coordinated sharing of resources (i.e. data, information, services, etc) on the Internet. Grid and Web DCIs have much in common as a result of their underlying Internet technology (protocols, models and specifications). However, being based on different requirements and architectural approaches, they show some differences as well. The Web's "major goal was to be a shared information space through which people and machines could communicate" [Berners-Lee 1996]. The success of the Web, and its consequent pervasiveness, made it appealing for building specialized systems like the Spatial Data Infrastructures (SDIs). In this systems the introduction of Web-based geo-information technologies enables specialized services for geospatial data sharing and processing. The Grid was born to achieve "flexible, secure, coordinated resource sharing among dynamic collections of individuals, institutions, and resources" [Foster 2001]. It specifically focuses on large-scale resource sharing, innovative applications, and, in some cases, high-performance orientation. In the Earth and Space Sciences (ESS) the most part of handled information is geo-referred (geo-information) since spatial and temporal meta-information is of primary importance in many application domains: Earth Sciences, Disasters Management, Environmental Sciences, etc. On the other hand, in several application areas there is the need of running complex models which require the large processing and storage capabilities that the Grids are able to provide. Therefore the integration of geo-information and Grid technologies might be a valuable approach in order to enable advanced ESS applications. Currently both geo-information and Grid technologies have reached a high level of maturity, allowing to build such an

  3. The GridShare solution: a smart grid approach to improve service provision on a renewable energy mini-grid in Bhutan

    Quetchenbach, T G; Harper, M J; Jacobson, A E; Robinson IV, J; Hervin, K K; Chase, N A; Dorji, C

    2013-01-01

    This letter reports on the design and pilot installation of GridShares, devices intended to alleviate brownouts caused by peak power use on isolated, village-scale mini-grids. A team consisting of the authors and partner organizations designed, built and field-tested GridShares in the village of Rukubji, Bhutan. The GridShare takes an innovative approach to reducing brownouts by using a low cost device that communicates the state of the grid to its users and regulates usage before severe brownouts occur. This demand-side solution encourages users to distribute the use of large appliances more evenly throughout the day, allowing power-limited systems to provide reliable, long-term renewable electricity to these communities. In the summer of 2011, GridShares were installed in every household and business connected to the Rukubji micro-hydro mini-grid, which serves approximately 90 households with a 40 kW nominal capacity micro-hydro system. The installation was accompanied by an extensive education program. Following the installation of the GridShares, the occurrence and average length of severe brownouts, which had been caused primarily by the use of electric cooking appliances during meal preparation, decreased by over 92%. Additionally, the majority of residents surveyed stated that now they are more certain that their rice will cook well and that they would recommend installing GridShares in other villages facing similar problems.

    2011-01-01

    We describe the use of F5's BIG-IP smart switch technology (3600 Series and Local Traffic Manager v9.0) to provide load balancing and automatic fail-over to multiple Grid services (GUMS, VOMS) and their associated back-end MySQL databases. This resiliency is introduced in front of the external application servers and also for the back-end database systems, which is what makes it 'multi-tier'. The combination of solutions chosen to ensure high availability of the services, in particular the database replication and fail-over mechanism, are discussed in detail. The paper explains the design and configuration of the overall system, including virtual servers, machine pools, and health monitors (which govern routing), as well as the master-slave database scheme and fail-over policies and procedures. Pre-deployment planning and stress testing will be outlined. Integration of the systems with our Nagios-based facility monitoring and alerting is also described. And application characteristics of GUMS and VOMS which enable effective clustering will be explained. We then summarize our practical experiences and real-world scenarios resulting from operating a major US Grid center, and assess the applicability of our approach to other Grid services in the future.

  6. [Universal coverage of health services in Mexico].

    2013-01-01

    The reforms made in recent years to the Mexican Health System have reduced inequities in the health care of the population, but have been insufficient to solve all the problems of the MHS. In order to make the right to health protection established in the Constitution a reality for every citizen, Mexico must warrant effective universal access to health services. This paper outlines a long-term reform for the consolidation of a health system that is akin to international standards and which may establish the structural conditions to reduce coverage inequity. This reform is based on a "structured pluralism" intended to avoid both a monopoly exercised within the public sector and fragmentation in the private sector, and to prevent falling into the extremes of authoritarian procedures or an absence of regulation. This involves the replacement of the present vertical integration and segregation of social groups by a horizontal organization with separation of duties. This also entails legal and fiscal reforms, the reinforcement of the MHS, the reorganization of health institutions, and the formulation of regulatory, technical and financial instruments to operationalize the proposed scheme with the objective of rendering the human right to health fully effective for the Mexican people.

  7. Data Distribution Service-Based Interoperability Framework for Smart Grid Testbed Infrastructure

    Tarek A. Youssef

    2016-03-01

    Full Text Available This paper presents the design and implementation of a communication and control infrastructure for smart grid operation. The proposed infrastructure enhances the reliability of the measurements and control network. The advantages of utilizing the data-centric over message-centric communication approach are discussed in the context of smart grid applications. The data distribution service (DDS is used to implement a data-centric common data bus for the smart grid. This common data bus improves the communication reliability, enabling distributed control and smart load management. These enhancements are achieved by avoiding a single point of failure while enabling peer-to-peer communication and an automatic discovery feature for dynamic participating nodes. The infrastructure and ideas presented in this paper were implemented and tested on the smart grid testbed. A toolbox and application programing interface for the testbed infrastructure are developed in order to facilitate interoperability and remote access to the testbed. This interface allows control, monitoring, and performing of experiments remotely. Furthermore, it could be used to integrate multidisciplinary testbeds to study complex cyber-physical systems (CPS.

  8. Final Progress Report for 'An Abstract Job Handling Grid Service for Dataset Analysis'

    David A Alexander

    2005-01-01

    For Phase I of the Job Handling project, Tech-X has built a Grid service for processing analysis requests, as well as a Graphical User Interface (GUI) client that uses the service. The service is designed to generically support High-Energy Physics (HEP) experimental analysis tasks. It has an extensible, flexible, open architecture and language. The service uses the Solenoidal Tracker At RHIC (STAR) experiment as a working example. STAR is an experiment at the Relativistic Heavy Ion Collider (RHIC) at the Brookhaven National Laboratory (BNL). STAR and other experiments at BNL generate multiple Petabytes of HEP data. The raw data is captured as millions of input files stored in a distributed data catalog. Potentially using thousands of files as input, analysis requests are submitted to a processing environment containing thousands of nodes. The Grid service provides a standard interface to the processing farm. It enables researchers to run large-scale, massively parallel analysis tasks, regardless of the computational resources available in their location

  9. Empowering the end-user in smart grids: Recommendations for the design of products and services

    Geelen, Daphne; Reinders, Angèle; Keyson, David

    2013-01-01

    In discussions on smart grids, it is often stated that residential end-users will play a more active role in the management of electric power supply and demand. They are expected to shift from a passive role as consumer of electricity to an active role as co-provider. In this article, the extent to which current technologies, products and services empower end-users to take up an active role as co-providers is evaluated. Based on a review of literature and related pilot projects, current approaches were found to be driven by technical and financial considerations. There appears to be a lack of product and service design that supports end-users in their role as co-providers in a smart grid. This is reflected in the lack of thought given to how the end-users’ process of behavioral change can be supported to enable the transition from consumer to co-provider. Several recommendations are provided for product and service designers towards fostering the role of co-provider, which comes under under: (a) user interaction needs, (b) approaches to behavioral change and (c) community initiatives and management of resources. Designers are considered to play a bridging role between policy making and engineering, while facilitating involvement of end-users in the design process. - Highlights: • Overview of products and services for residential end-users in smart grids. • Evaluation of extent to which end-users are empowered to adopt a co-provider role. • Products and services often focus on technical functionality and financial incentives. • Behavioral aspects and social context would have to be taken into account more. • Design recommendations are proposed to empower end-users in becoming co-providers

  11. Geospatial Information Service System Based on GeoSOT Grid & Encoding

    LI Shizhong

    2016-12-01

    Full Text Available With the rapid development of the space and earth observation technology, it is important to establish a multi-source, multi-scale and unified cross-platform reference for global data. In practice, the production and maintenance of geospatial data are scattered in different units, and the standard of the data grid varies between departments and systems. All these bring out the disunity of standards among different historical periods or orgnizations. Aiming at geospatial information security library for the national high resolution earth observation, there are some demands for global display, associated retrieval and template applications and other integrated services for geospatial data. Based on GeoSOT grid and encoding theory system, "geospatial information security library information of globally unified grid encoding management" data subdivision organization solutions have been proposed; system-level analyses, researches and designs have been carried out. The experimental results show that the data organization and management method based on GeoSOT can significantly improve the overall efficiency of the geospatial information security service system.

  19. An Experimental Evaluation of the DQ-DHT Algorithm in a Grid Information Service

    Papadakis, Harris; Trunfio, Paolo; Talia, Domenico; Fragopoulou, Paraskevi

    DQ-DHT is a resource discovery algorithm that combines the Dynamic Querying (DQ) technique used in unstructured peer-to-peer networks with an algorithm for efficient broadcast over a Distributed Hash Table (DHT). Similarly to DQ, DQ-DHT dynamically controls the query propagation on the basis of the desired number of results and the popularity of the resource to be located. Differently from DQ, DQ-DHT exploits the structural properties of a DHT to avoid message duplications, thus reducing the amount of network traffic generated by each query. The goal of this paper is to evaluate experimentally the amount of traffic generated by DQ-DHT compared to the DQ algorithm in a Grid infrastructure. A prototype of a Grid information service, which can use both DQ and DQ-DHT as resource discovery algorithm, has been implemented and deployed on the Grid'5000 infrastructure for evaluation. The experimental results presented in this paper show that DQ-DHT significantly reduces the amount of network traffic generated during the discovery process compared to the original DQ algorithm.

  3. Vehicle to Grid regulation services of electric delivery trucks: Economic and environmental benefit analysis

    Zhao, Yang; Noori, Mehdi; Tatari, Omer

    2016-01-01

    Highlights: • Potential net present revenues of electric truck based V2G regulation services are investigated. • GHG emission mitigation of V2G regulation services provided by electric trucks are quantified. • The total cost of ownership and the life-cycle GHG emissions of electric trucks are also analyzed. • V2G regulation services for electric trucks could yield considerable revenues and GHG emission savings. - Abstract: Concerns regarding the fuel costs and climate change impacts associated with petroleum combustion are among the main driving factors for the adoption of electric vehicles. Future commercial delivery truck fleets may include Battery Electric Vehicles (BEVs) and Extended Range Electric Vehicles (EREVs); in addition to savings on fuel and maintenance costs, the introduction of these grid accessible electric vehicles will also provide fleet owners with possible Vehicle to Grid (V2G) opportunities. This study investigates the potential net present revenues and greenhouse gas (GHG) emission mitigation of V2G regulation services provided by electric trucks in a typical fleet. The total cost of ownership and the life-cycle GHG emissions of electric trucks are also analyzed and compared to those of traditional diesel trucks. To account for uncertainties, possible ranges for key parameters are considered instead of only considering fixed single data values for each parameter. The results of this research indicate that providing V2G regulation services for electric trucks could yield considerable additional revenues ($20,000–50,000) and significant GHG emission savings (approximately 300 ton CO_2) compared to conventional diesel trucks.

  5. The open science grid

    Pordes, R.

    2004-01-01

    The U.S. LHC Tier-1 and Tier-2 laboratories and universities are developing production Grids to support LHC applications running across a worldwide Grid computing system. Together with partners in computer science, physics grid projects and active experiments, we will build a common national production grid infrastructure which is open in its architecture, implementation and use. The Open Science Grid (OSG) model builds upon the successful approach of last year's joint Grid2003 project. The Grid3 shared infrastructure has for over eight months provided significant computational resources and throughput to a range of applications, including ATLAS and CMS data challenges, SDSS, LIGO, and biology analyses, and computer science demonstrators and experiments. To move towards LHC-scale data management, access and analysis capabilities, we must increase the scale, services, and sustainability of the current infrastructure by an order of magnitude or more. Thus, we must achieve a significant upgrade in its functionalities and technologies. The initial OSG partners will build upon a fully usable, sustainable and robust grid. Initial partners include the US LHC collaborations, DOE and NSF Laboratories and Universities and Trillium Grid projects. The approach is to federate with other application communities in the U.S. to build a shared infrastructure open to other sciences and capable of being modified and improved to respond to needs of other applications, including CDF, D0, BaBar, and RHIC experiments. We describe the application-driven, engineered services of the OSG, short term plans and status, and the roadmap for a consortium, its partnerships and national focus

  6. The Determination of Jurisdiction in Grid and Cloud Service Level Agreements

    Parrilli, Davide Maria

    Service Level Agreements in Grid and Cloud scenarios can be a source of disputes particularly in case of breach of the obligations arising under them. It is then important to determine where parties can litigate in relation with such agreements. The paper deals with this question in the peculiar context of the European Union, and so taking into consideration Regulation 44/2001. According to the rules on jurisdiction provided by the Regulation, two general distinctions are drawn in order to determine which (European) courts are competent to adjudicate disputes arising out of a Service Level Agreement. The former is between B2B and B2C transactions, and the latter regards contracts which provide a jurisdiction clause and contracts which do not.

  7. Collaborative Science Using Web Services and the SciFlo Grid Dataflow Engine

    Wilson, B. D.; Manipon, G.; Xing, Z.; Yunck, T.

    2006-12-01

    The General Earth Science Investigation Suite (GENESIS) project is a NASA-sponsored partnership between the Jet Propulsion Laboratory, academia, and NASA data centers to develop a new suite of Web Services tools to facilitate multi-sensor investigations in Earth System Science. The goal of GENESIS is to enable large-scale, multi-instrument atmospheric science using combined datasets from the AIRS, MODIS, MISR, and GPS sensors. Investigations include cross-comparison of spaceborne climate sensors, cloud spectral analysis, study of upper troposphere-stratosphere water transport, study of the aerosol indirect cloud effect, and global climate model validation. The challenges are to bring together very large datasets, reformat and understand the individual instrument retrievals, co-register or re-grid the retrieved physical parameters, perform computationally-intensive data fusion and data mining operations, and accumulate complex statistics over months to years of data. To meet these challenges, we have developed a Grid computing and dataflow framework, named SciFlo, in which we are deploying a set of versatile and reusable operators for data access, subsetting, registration, mining, fusion, compression, and advanced statistical analysis. SciFlo leverages remote Web Services, called via Simple Object Access Protocol (SOAP) or REST (one-line) URLs, and the Grid Computing standards (WS-* &Globus Alliance toolkits), and enables scientists to do multi-instrument Earth Science by assembling reusable Web Services and native executables into a distributed computing flow (tree of operators). The SciFlo client &server engines optimize the execution of such distributed data flows and allow the user to transparently find and use datasets and operators without worrying about the actual location of the Grid resources. In particular, SciFlo exploits the wealth of datasets accessible by OpenGIS Consortium (OGC) Web Mapping Servers & Web Coverage Servers (WMS/WCS), and by Open Data

  8. Allocation of reactive power support, active loss balancing and demand interruption ancillary services in MicroGrids

    Gomes, Mario Helder [Departamento de Engenharia Electrotecnica, Instituto Politecnico de Tomar, Quinta do Contador, Estrada da Serra, 2300 Tomar (Portugal); Saraiva, Joao Tome [INESC Porto and Faculdade de Engenharia da Universidade do Porto, Campus da FEUP, Rua Dr. Roberto Frias, 4200 - 465 Porto (Portugal)

    2010-10-15

    MicroGrids represent a new paradigm for the operation of distribution systems and there are several advantages as well as challenges regarding their development. One of the advantages is related with the participation of MicroGrid agents in electricity markets and in the provision of ancillary services. This paper describes two optimization models to allocate three ancillary services among MicroGrid agents - reactive power/voltage control, active loss balancing and demand interruption. These models assume that MicroGrid agents participate in the day-ahead market sending their bids to the MicroGrid Central Controller, MGCC, that acts as an interface with the Market Operator. Once the Market Operator returns the economic dispatch of the MicroGrid agents, the MGCC checks its technical feasibility (namely voltage magnitude and branch flow limits) and activates an adjustment market to change the initial schedule and to allocate these three ancillary services. One of the models has crisp nature considering that voltage and branch flow limits are rigid while the second one admits that voltage and branch flow limits are modeled in a soft way using Fuzzy Set concepts. Finally, the paper illustrates the application of these models with a Case Study using a 55 node MV/LV network. (author)

  9. A Worldwide Production Grid Service Built on EGEE and OSG Infrastructures Lessons Learnt and Long-term Requirements

    Shiers, J.; Dimou, M.; Mendez Lorenzo, P.

    2007-01-01

    Using the Grid Infrastructures provided by EGEE, OSG and others, a worldwide production service has been built that provides the computing and storage needs for the 4 main physics collaborations at CERN's Large Hadron Collider (LHC). The large number of users, their geographical distribution and the very high service availability requirements make this experience of Grid usage worth studying for the sake of a solid and scalable future operation. This service must cater for the needs of thousands of physicists in hundreds of institutes in tens of countries. A 24x7 service with availability of up to 99% is required with major service responsibilities at each of some ten T ier1 a nd of the order of one hundred T ier2 s ites. Such a service - which has been operating for some 2 years and will be required for at least an additional decade - has required significant manpower and resource investments from all concerned and is considered a major achievement in the field of Grid computing. We describe the main lessons learned in offering a production service across heterogeneous Grids as well as the requirements for long-term operation and sustainability. (Author)

    Advanced visualization technologies are gaining major importance to allow presentation and manipulation of high dimensional data. Since new health technologies are constantly increasing in complexity, adequate information processing is required for diagnostics and treatment. Therefore, the German D-Grid initiative started to build visualization centers in 2008, which have recently been embedded into the existing compute and storage infrastructure. This paper describes an analysis of this infrastructure and the interplay with life science applications for 3D and 4D visualization and manipulation. Furthermore, the performance and business aspects regarding accounting, pricing and billing are investigated. The results show the viability and the opportunities for further optimization of this novel service approach and the possibilities for a sustainable business scenario.

    Farzandipour, Mehrdad; Meidani, Zahra

    2014-06-01

    Websites as one of the initial steps towards an e-government adoption do facilitate delivery of online and customer-oriented services. In this study we intended to investigate the role of the websites of medical universities in providing educational and research services following the E-government maturity model in the Iranian universities. This descriptive and cross- sectional study was conducted through content analysis and benchmarking the websites in 2012. The research population included the entire medical university website (37). Delivery of educational and research services through these university websites including information, interaction, transaction, and Integration were investigated using a checklist. The data were then analyzed by means of descriptive statistics and using SPSS software. Level of educational and research services by websites of the medical universities type I and II was evaluated medium as 1.99 and 1.89, respectively. All the universities gained a mean score of 1 out of 3 in terms of integration of educational and research services. Results of the study indicated that Iranian universities have passed information and interaction stages, but they have not made much progress in transaction and integration stages. Failure to adapt to e-government in Iranian medical universities in which limiting factors such as users' e-literacy, access to the internet and ICT infrastructure are not so crucial as in other organizations, suggest that e-government realization goes beyond technical challenges.

  4. THE CONSTRUCTION OF IMPORTANCE-PERFORMANCE GRID IN TOURIST SERVICES RESEARCH WITHOUT THE DIRECT DETERMINATION OF THE ATTRIBUTES IMPORTANCE

    Ban Olimpia

    2012-07-01

    Full Text Available The importance-performance grid is a marketing instrument used to make decisions regarding the growth of the consumers’ satisfaction, by optimizing the attributes of products. This grid is a useful instrument, as it is shown in the paper, to the extent to which the importance and performance of the attributes are correctly recorded. Another idea underlined in the paper is that regarding the difficulty to directly determine the importance of attributes or in the same stage with the determination of the service performance, according to these attributes. The objectives of this paper are to analyze the importance-performance grid (suggested by Martilla and amended by Abalo,through an empirical study in the field of tourist services used and to test the conditions to carry out this grid taking into account the hypothetical case of indirectly determining the importance of the quality attributes. The literature in the field regarding the importance-performance analysis is analysed and the subsequent amendments to the previous grid suggested by Martilla and James in 1977. The present paper is a continuation of several studies on the same subject, in which the following research methods were used: direct survey by questionnaire, the Spearman correlation coefficient, and the entropy calculus. A comparative analysis of the importance-performance grid if directly recording the importance of attributes (through survey by questionnaire and of the indirect determination of the importance of the attributes (through the Spearman coefficient and entropy calculus is being suggested. The results indicate possible uses of methods, yet it raises a series of collateral problems regarding their application. The contribution of this paper is given by the suggestion of two methods to indirectly determine the importance of attributes, which take into account the data measurement scale used and the collinearity among attributes and which lead to pertinent results

  10. Multicriteria Analysis for universalization of electricity services in isolated rural households in the region Norte Fluminense

    Luiz Mendes

    2015-02-01

    Full Text Available Besides hydropower Brazil has considerable potential wind and solar that can contribute to the universalization of electricity services in remote communities. This is because the program “Luz para todos” has a high cost to the wild places and thus, the universal becomes uneconomical. In the present study, we used the AHP method classic and Borda for multicriteria problems with the objective of choosing the type of supply electricity to an isolated rural domicile with average consumption of 150kWh of electricity and located in the northern region of Rio de Janeiro. For this, we considered four alternatives based on quantitative and qualitative criteria and modeled in six different situations, which are corresponding to distances from houses to the mains conventional dealership. We performed the modeling of the problem with the AHP to select the best source of energy supply, then immediately applied the Borda method for ranking of alternative sources of energy supply, and finally, we propose a new methodology for integration of AHP method to the Borda. Thus, the application of the two methods separately and also the new proposal of integration of these showed similar results as the best alternative for the supply of electricity to the rural domicile isolated situations in the six proposals. Since the supply of conventional dealership was the best alternative for zero distance 500 meters (cases one and two for both methods applied, but for other situations renewables become viable in relation to the grid the concessionaire. Worked so pointed that the greater the distance from houses to the grid, the greater the viability of renewable energy. Furthermore, the results show that renewables can contribute to meeting the demand for electricity in isolated communities and also point to the need to review the policies of universal electrical services in view of the potential wind and solar to be explored in Northern region of the state of Rio de

    Jonsen, B.O. (Solar Danmark A/S, Vejen (Denmark)); Hauge, B. (IT-Branchen, Copenhagen (Denmark)); Strunge, C. (Energinet.dk, Fredericia (Denmark)) (and others)

    2011-07-01

    The Smart Grid Network was established in 2010 by the Danish climate and energy minister tasked with developing recommendations for future actions and initiatives that make it possible to handle up to 50% electricity from wind energy in the power system in 2020. The task of working group 4 was to investigate what it takes to involve consumers in smart grid and how to create good conditions for new services related to smart grid. Against this background, the working group agreed the following recommendations: 1) Enhance consumer engagement. A prerequisite for electricity customers becoming involved in smart grid is that they have awareness and knowledge about the smart grid and their own possibilities for action in relation thereto. Therefore it is important that concepts such as smart grid and flexible electricity consumption gradually become popular among electric customers; 2) Minimize the risk. In order to promote electric customers' and other stakeholders' participation in the smart grid, the risk of this participation must be minimized. It is therefore recommended to enhance the skills of the professionals and to establish a common framework for security; 3) Make it easier to create new services. Part of the potential of smart grid can be realized through new services such as delivery of flexible electricity consumption for electric cars and heat pumps and the resale of local power generation at the customer. To facilitate the conditions for these services, the working group recommends that better access to relevant data is created, that the interoperability of smart grid solutions is strengthened, that requirements for buildings are made, that it is made easier to be an aggregator, and that test and inspiration laboratories for small and medium enterprises in the smart grid area are established.

  12. Pricing of Vehicle-to-Grid Services in a Microgrid by Nash Bargaining Theory

    Mohammad Hossein Sarparandeh

    2017-01-01

    Full Text Available Owners of electric vehicles (EVs can offer the storage capacity of their batteries to the operator of a microgrid as a service called vehicle-to-grid (V2G to hold the balance between supply and demand of electricity, particularly when the microgrid has intermittent renewable energy sources. Literature review implies that V2G has economic benefits for both microgrid operator and EV owners, but it is unclear how these benefits are divided between them. The challenge grows when the policy makers rely on the V2G revenue as an incentive for expanding the penetration of EVs in the automotive market. This paper models the interaction between microgrid operator and EV owners as a bargaining game to determine how the benefits of V2G should be divided. The method has been implemented on a hybrid power system with high wind penetration in addition to diesel generators in Manjil, Iran. The results indicate that, in addition to V2G benefits, government subsidies are necessary to promote the use of EVs.

  13. Employing peer-to-peer software distribution in ALICE Grid Services to enable opportunistic use of OSG resources

    CERN. Geneva; Sakrejda, Iwona

    2012-01-01

    The ALICE Grid infrastructure is based on AliEn, a lightweight open source framework built on Web Services and a Distributed Agent Model in which job agents are submitted onto a grid site to prepare the environment and pull work from a central task queue located at CERN. In the standard configuration, each ALICE grid site supports an ALICE-specific VO box as a single point of contact between the site and the ALICE central services. VO box processes monitor site utilization and job requests (ClusterMonitor), monitor dynamic job and site properties (MonaLisa), perform job agent submission (CE) and deploy job-specific software (PackMan). In particular, requiring a VO box at each site simplifies deployment of job software, done onto a shared file system at the site, and adds redundancy to the overall Grid system. ALICE offline computing, however, has also implemented a peer-to-peer method (based on BitTorrent) for downloading job software directly onto each worker node as needed. By utilizing both this peer-...

  14. Grid interoperability: joining grid information systems

    Flechl, M; Field, L

    2008-01-01

    A grid is defined as being 'coordinated resource sharing and problem solving in dynamic, multi-institutional virtual organizations'. Over recent years a number of grid projects, many of which have a strong regional presence, have emerged to help coordinate institutions and enable grids. Today, we face a situation where a number of grid projects exist, most of which are using slightly different middleware. Grid interoperation is trying to bridge these differences and enable Virtual Organizations to access resources at the institutions independent of their grid project affiliation. Grid interoperation is usually a bilateral activity between two grid infrastructures. Recently within the Open Grid Forum, the Grid Interoperability Now (GIN) Community Group is trying to build upon these bilateral activities. The GIN group is a focal point where all the infrastructures can come together to share ideas and experiences on grid interoperation. It is hoped that each bilateral activity will bring us one step closer to the overall goal of a uniform grid landscape. A fundamental aspect of a grid is the information system, which is used to find available grid services. As different grids use different information systems, interoperation between these systems is crucial for grid interoperability. This paper describes the work carried out to overcome these differences between a number of grid projects and the experiences gained. It focuses on the different techniques used and highlights the important areas for future standardization

  15. Stakeholder Expectations of Service Quality in a University Web Portal

    Tate, Mary; Evermann, Joerg; Hope, Beverley; Barnes, Stuart

    Online service quality is a much-studied concept. There is considerable evidence that user expectations and perceptions of self-service and online service quality differ in different business domains. In addition, the nature of online services is continually changing and universities have been at the forefront of this change, with university websites increasingly acting as a portal for a wide range of online transactions for a wide range of stakeholders. In this qualitative study, we conduct focus groups with a range of stakeholders in a university web portal. Our study offers a number of insights into the changing nature of the relationship between organisations and customers. New technologies are influencing customer expectations. Customers increasingly expect organisations to have integrated information systems, and to utilise new technologies such as SMS and web portals. Organisations can be slow to adopt a customer-centric viewpoint, and persist in providing interfaces that are inconsistent or require inside knowledge of organisational structures and processes. This has a negative effect on customer perceptions.

  16. Emissions impacts and benefits of plug-in hybrid electric vehicles and vehicle-to-grid services.

    Sioshansi, Ramteen; Denholm, Paul

    2009-02-15

    Plug-in hybrid electric vehicles (PHEVs) have been promoted as a potential technology to reduce emissions of greenhouse gases and other pollutants by using electricity instead of petroleum, and byimproving electric system efficiency by providing vehicle-to-grid (V2G) services. We use an electric power system model to explicitly evaluate the change in generator dispatches resulting from PHEV deployment in the Texas grid, and apply fixed and non-parametric estimates of generator emissions rates, to estimate the resulting changes in generation emissions. We find that by using the flexibility of when vehicles may be charged, generator efficiency can be increased substantially. By changing generator dispatch, a PHEVfleet of up to 15% of light-duty vehicles can actually decrease net generator NOx emissions during the ozone season, despite the additional charging load. By adding V2G services, such as spinning reserves and energy storage, CO2, SO2, and NOx emissions can be reduced even further.

  17. Controllable Grid Interface for Testing Ancillary Service Controls and Fault Performance of Utility-Scale Wind Power Generation: Preprint

    Gevorgian, Vahan; Koralewicz, Przemyslaw; Wallen, Robb; Muljadi, Eduard

    2017-02-01

    The rapid expansion of wind power has led many transmission system operators to demand modern wind power plants to comply with strict interconnection requirements. Such requirements involve various aspects of wind power plant operation, including fault ride-through and power quality performance as well as the provision of ancillary services to enhance grid reliability. During recent years, the National Renewable Energy Laboratory (NREL) of the U.S. Department of Energy has developed a new, groundbreaking testing apparatus and methodology to test and demonstrate many existing and future advanced controls for wind generation (and other renewable generation technologies) on the multimegawatt scale and medium-voltage levels. This paper describes the capabilities and control features of NREL's 7-MVA power electronic grid simulator (also called a controllable grid interface, or CGI) that enables testing many active and reactive power control features of modern wind turbine generators -- including inertial response, primary and secondary frequency responses, and voltage regulation -- under a controlled, medium-voltage grid environment. In particular, this paper focuses on the specifics of testing the balanced and unbalanced fault ride-through characteristics of wind turbine generators under simulated strong and weak medium-voltage grid conditions. In addition, this paper provides insights on the power hardware-in-the-loop feature implemented in the CGI to emulate (in real time) the conditions that might exist in various types of electric power systems under normal operations and/or contingency scenarios. Using actual test examples and simulation results, this paper describes the value of CGI as an ultimate modeling validation tool for all types of 'grid-friendly' controls by wind generation.

  18. Heterogenous customer satisfaction index for evaluating university food service

    Aziz, Nazrina; Zain, Zakiyah; Syarifi, Nadia Asyikin Mohammad; Klivon, Julia; Ap, Nurasiah Che; Zaki, Mahirah

    2017-11-01

    This paper aims to measure the performance of university food service based on students' perception. Two cafeterias were chosen for comparison: one located at student residential hall (Café 1) and another at the university administration centre (Café 2). By considering the components of importance and satisfaction, the Heterogeneous Customer Satisfaction Index-HCSI was computed to measure the performance of quality items in both cafeterias. Stratified sampling method was used to select 278 students and the DINESERVE instrument was used to assess customer perception on service quality. The findings show that the customer rate these two cafeterias as quite satisfied only, with the HCSI for Café 1 slightly higher than that for Café 2.

  20. Homeless university students: Experiences with foyer-type service

    Marty Grace

    2012-06-01

    Full Text Available Some young people who have been homeless during their secondary schooling manage to obtain a university place. These young people, and others who become homeless during their university courses, have the opportunity to build a sustainable exit from homelessness through education and support. Very little is known about how many young Australians are in this situation, or what can be done to assist them to complete their degrees. This article reports on research that aimed to document the experiences of 11 university students who had experienced homelessness. The research focussed on the difficulties that these young people faced, and the types of environments and service responses that can make a difference for them. The students were part of a larger study of a foyer-type service. The research found that these young people took longer than the standard duration to complete their degrees. Their study was facilitated by provision of stable, safe accommodation and support when they were acutely homeless, relief from other pressures such as family conflict, protection while maturing, time for overseas born including refugee young people to develop language, skills, and resources, support to heal from past damaging experiences and improve their health, assistance to gain entry to preferred university courses, and pathways into stable housing for the duration of their study.

  1. Monitoring CMS tracker construction and data quality using a Grid/Web service based on a visualization tool

    Zito, Giuseppe; Regano, A

    2004-01-01

    The complexity of the CMS tracker (more than 50 million channels to monitor) now in construction in ten laboratories worldwide with hundreds of interested people, will require new tools for monitoring both the hardware and the software. In our approach we use both visualization tools and Grid services to make this monitoring possible. The use of visualization enables us to represent in a single computer screen all those million channels at once. The Grid will make it possible to get enough data and computing power in order to check every channel and also to reach the experts everywhere in the world allowing the early discovery of problems. We report here on a first prototype developed using the Grid environment already available now in CMS i.e. LCG2. This prototype consists on a Java client which implements the GUI for tracker visualization and two data servers connected to the tracker construction database and to Grid catalogs of event datasets. All the communication between client and servers is done using ...

    2013-01-01

    Experiences of the Laboratory for Instrumental Neutron Activation Analysis (INAA) of the Reactor Institute Delft at the Delft University of Technology are presented on basis of more than 30 years experience with INAA services to others. Recommendations are given to neutron activation analysis groups starting as a service provider, but also pitfalls are identified. The importance of fitness for intended purpose is emphasized, so that analysis protocols should be optimized to answer the customer’s basic question, rather than to yield the highest number of elements and best level of precision. The absence of automation and no return of revenues are identified as highest threats of becoming a successful and reliable partner for providing services. (author)

  4. An application of ETICS Co-Scheduling Mechanism to Interoperability and Compliance Validation of Grid Services

    Ronchieri, Elisabetta; Diez-andino Sancho, Guillermo; DI Meglio, Alberto; Marzolla, Moreno

    2008-01-01

    Grid software projects require infrastructures in order to evaluate interoperability with other projects and compliance with predefined standards. Interoperability and compliance are quality attributes that are expected from all distributed projects. ETICS is designed to automate the investigation of this kind of problems. It integrates well-established procedures, tools and resources in a coherent framework and adaptes them to the special needs of these projects. Interoperability and compliance to standards are important quality attributes of software developed for Grid environments where many different parts of an interconnected system have to interact. Compliance to standard is one of the major factors in making sure that interoperating parts of a distributed system can actually interconnect and exchange information. Taking the case of the Grid environment (Foster and Kesselman, 2003), most of the projects that are developing software have not reached the maturity level of other communities yet and have di...

    2009-01-01

    Full Text Available Ensuring universal service is a top objective in many countries in order that all the citizens can have access basic communications services. Although the ICT equipment in households and its usage by individuals are essential prerequisites for benefiting from ICTs, the situation in the European Union is far from uniform. This article provides a description of the European information society development scenario using the values reached by the member states in a set of indicators selected for measuring said progress in households. Two tools are used for providing a broader perspective of the digital divide: a composite index and the cluster analysis. Below, a study is provided on what variables are relevant for interpreting the situation that is presented.

We conducted systematic, experimental study about how DoS attacks affect message delivery delays.

  12. Mechanisms of Funding for Universal Service Obligations: the Electricity Case

    Mirabel, Francois; Poudou, Jean-Christophe

    2001-06-01

    The transition towards a more competitive regime in network industries (and specially in electricity sector) raises the relevant question of funding for the Universal Service Obligations (USOs). Our paper focuses on two ways of funding for universal service and equal treatment obligations (?Ubiquity and Non Discrimination constraints?): the funding through access charge (CS regime) or taxation (T regime). Using a network model including competition between an historical monopoly (in charge for the USOs) and an entrant, we obtain some results concerning gains and losses of social welfare due to those mechanisms. We show that most of the time it is socially better to let the historical monopoly be active whatever the type of funding for USOs applying, and whatever profitability of the firms is. However, when the entrant is active, we can highlight that the introduction of the T regime (compared to the CS one) implies either welfare deterioration or an entry prevention strategy by the historical firm. Therefore, the T regime could not be an argument for the regulator to promote vertical separation of the historical firm (according to the European community line). (authors)

  15. A socio-technical investigation of the smart grid: Implications for demand-side activities of electricity service providers

    Corbett, Jacqueline Marie

    Enabled by advanced communication and information technologies, the smart grid represents a major transformation for the electricity sector. Vast quantities of data and two-way communications abilities create the potential for a flexible, data-driven, multi-directional supply and consumption network well equipped to meet the challenges of the next century. For electricity service providers ("utilities"), the smart grid provides opportunities for improved business practices and new business models; however, a transformation of such magnitude is not without risks. Three related studies are conducted to explore the implications of the smart grid on utilities' demand-side activities. An initial conceptual framework, based on organizational information processing theory, suggests that utilities' performance depends on the fit between the information processing requirements and capacities associated with a given demand-side activity. Using secondary data and multiple regression analyses, the first study finds, consistent with OIPT, a positive relationship between utilities' advanced meter deployments and demand-side management performance. However, it also finds that meters with only data collection capacities are associated with lower performance, suggesting the presence of information waste causing operational inefficiencies. In the second study, interviews with industry participants provide partial support for the initial conceptual model, new insights are gained with respect to information processing fit and information waste, and "big data" is identified as a central theme of the smart grid. To derive richer theoretical insights, the third study employs a grounded theory approach examining the experience of one successful utility in detail. Based on interviews and documentary data, the paradox of dynamic stability emerges as an essential enabler of utilities' performance in the smart grid environment. Within this context, the frames of opportunity, control, and data

  16. The universal service in the future of network-type industries: telecommunications, electricity, postal services

    Bremond, Celine Clelia

    2003-01-01

    The notion of universal service emerged in the European regulation of the telecommunications sector, and can be applied to all network-type industries. Public monopolies have been put into question again. The introduction of deregulation and competitiveness were expected to improve the service provided to the end consumer, but this deregulation has been also put into question again for matters of universality and equity. Then the issue of financing of these services emerges. The aim of this research thesis is therefore to identify which funding modes can be optimal, and to identify a general methodology for all network-type industries. In the first part of this research thesis, the author studies the cost of universal service obligations. She explains the general methodology of calculation of this cost, and reports this calculation while taking indirect benefits of the operator into account. In a second part, she studies the modalities of financing thus calculated cost by describing the different possible modalities, their benefits and drawbacks, and by presenting a comparison between these methodologies according to three criteria: those set by the European Commission, welfare, and applicability. For these different topics, the author takes all experiments and recent developments into account. These experiments and developments are noticed in different countries: USA, Australia, UK, Sweden, Netherlands, Germany, Belgium, Italy, France

  1. GENESIS SciFlo: Choreographing Interoperable Web Services on the Grid using a Semantically-Enabled Dataflow Execution Environment

    Wilson, B. D.; Manipon, G.; Xing, Z.

    2007-12-01

    The General Earth Science Investigation Suite (GENESIS) project is a NASA-sponsored partnership between the Jet Propulsion Laboratory, academia, and NASA data centers to develop a new suite of Web Services tools to facilitate multi-sensor investigations in Earth System Science. The goal of GENESIS is to enable large-scale, multi-instrument atmospheric science using combined datasets from the AIRS, MODIS, MISR, and GPS sensors. Investigations include cross-comparison of spaceborne climate sensors, cloud spectral analysis, study of upper troposphere-stratosphere water transport, study of the aerosol indirect cloud effect, and global climate model validation. The challenges are to bring together very large datasets, reformat and understand the individual instrument retrievals, co-register or re-grid the retrieved physical parameters, perform computationally-intensive data fusion and data mining operations, and accumulate complex statistics over months to years of data. To meet these challenges, we have developed a Grid computing and dataflow framework, named SciFlo, in which we are deploying a set of versatile and reusable operators for data access, subsetting, registration, mining, fusion, compression, and advanced statistical analysis. SciFlo leverages remote Web Services, called via Simple Object Access Protocol (SOAP) or REST (one-line) URLs, and the Grid Computing standards (WS-* & Globus Alliance toolkits), and enables scientists to do multi- instrument Earth Science by assembling reusable Web Services and native executables into a distributed computing flow (tree of operators). The SciFlo client & server engines optimize the execution of such distributed data flows and allow the user to transparently find and use datasets and operators without worrying about the actual location of the Grid resources. In particular, SciFlo exploits the wealth of datasets accessible by OpenGIS Consortium (OGC) Web Mapping Servers & Web Coverage Servers (WMS/WCS), and by Open Data

  3. "Dropbox-like" service for the University of Vienna

    CERN. Geneva

    2014-01-01

    The increasing popularity of dropbox and at the same time increasing awareness for data security did create the demand for an onsite "Dropbox-like" “sync and share” service at the University of Vienna. It has been decided that ownCloud would be a good start, since other academic institutions have been working on an ownCloud based solution as well. Based on ownCloud enterprise Version 6 the service is currently in test operation with campus wide availability for staff only planned for 12/2014. Major concerns were the scalability of the storage backend. So instead of using an enterprise storage solution we use Scality’s RING as backend. The RING is an object storage based solution using local storage nodes. Since the ownCloud architecture does so far not allow a RESTbased storage backend we use Scality’s FUSE connector to simulate a virtually limitless filesystem (POSIX). Based on the experiences reported by other academic facilities and our own, our main concerns have been database performance-scal...

  5. A Tale of Energy Transition and Tension: The Incomplete Universalization of the Natural Gas Grid in Istanbul

    Arik, Elvan

    2013-01-01

    Available studies on natural gas networks have so far made little contribution to an understanding of changes in urban management in emerging cities. However, the development of such energy systems, considered as cleaner and more efficient compared to previous systems based primarily on the use of traditional fuels (wood, coal, LPG, biofuels) leads these cities into an energy transition. This process is firstly characterized by the introduction of a new energy resource that then involves changes in certain domestic practices (such as, in our case study, heating and culinary practices). Focusing on the case of the development of the natural gas network in Istanbul, this paper studies the tensions inherent in this transformation. Socio-political and territorial analysis of the deployment of this network, which allows us to evaluate the actual universalization of the service, allows us to turn our attention away from the issue of access to the infrastructure and toward the concrete domestic uses of the service

  7. Exploring Distributed Energy Alternatives to Electrical Distribution Grid Expansion in Souhern California Edison Service Territory

    Stovall, Therese K [ORNL; Kingston, Tim [Gas Technology Institute

    2005-12-01

    Distributed energy (DE) technologies have received much attention for the energy savings and electric power reliability assurances that may be achieved by their widespread adoption. Fueling the attention have been the desires to globally reduce greenhouse gas emissions and concern about easing power transmission and distribution system capacity limitations and congestion. However, these benefits may come at a cost to the electric utility companies in terms of lost revenue and concerns with interconnection on the distribution system. This study assesses the costs and benefits of DE to both consumers and distribution utilities and expands upon a precursory study done with Detroit Edison (DTE)1, by evaluating the combined impact of DE, energy-efficiency, photovoltaics (a use of solar energy), and demand response that will shape the grid of the future. This study was funded by the U.S. Department of Energy (DOE), Gas Research Institute (GRI), American Electric Power (AEP), and Gas Technology Institute's (GTI) Distributed Energy Collaborative Program (DECP). It focuses on two real Southern California Edison (SCE) circuits, a 13 MW suburban circuit fictitiously named Justice on the Lincoln substation, and an 8 MW rural circuit fictitiously named Prosper on the Washington Substation. The primary objectives of the study were threefold: (1) Evaluate the potential for using advanced energy technologies, including DE, energy-efficiency (EE), demand response, electricity storage, and photovoltaics (PV), to reshape electric load curves by reducing peak demand, for real circuits. (2) Investigate the potential impact on guiding technology deployment and managing operation in a way that benefits both utilities and their customers by: (a) Improving grid load factor for utilities; (b) Reducing energy costs for customers; and (c) Optimizing electric demand growth. (3) Demonstrate benefits by reporting on a recently installed advanced energy system at a utility customer site

  14. Production grid systems and their programming

    Kacsuk, P; Stefan, P

    2004-01-01

    Summary form only given. There are a large variety of grid test-beds that can be used for experimental purposes by a small community. However, the number of production grid systems that can be used as a service for a large community is very limited. The current tutorial provides introduction to three of these very few production grid systems. They represent different models and policies of using grid resources and hence understanding and comparing them is an extremely useful exercise to everyone interested in grid technology. The Hungarian ClusterGrid infrastructure connects clusters during the nights and weekends. These clusters are used during the day for educational purposes at the Hungarian universities and polytechnics. Therefore, a unique feature of this grid is the switching mechanism by which the day time and night time working modes are loaded to the computers. In order to manage the system as a production, one, the system is homogeneous, all the machines should install the same grid software package...

    Severe weather events frequently result in large-scale power failures, affecting millions of people for extended durations. However, the lack of comprehensive, detailed failure and recovery data has impeded large-scale resilience studies. Here, we analyse data from four major service regions representing Upstate New York during Super Storm Sandy and daily operations. Using non-stationary spatiotemporal random processes that relate infrastructural failures to recoveries and cost, our data analysis shows that local power failures have a disproportionally large non-local impact on people (that is, the top 20% of failures interrupted 84% of services to customers). A large number (89%) of small failures, represented by the bottom 34% of customers and commonplace devices, resulted in 56% of the total cost of 28 million customer interruption hours. Our study shows that extreme weather does not cause, but rather exacerbates, existing vulnerabilities, which are obscured in daily operations.

  18. Operation and Management of Thermostatically Controlled Loads for Providing Regulation Services to Power Grids

    Vanouni, Maziar

    The notion of demand-side participation in power systems operation and control is on the verge of realization because of the advancement in the required technologies an tools like communications, smart meters, sensor networks, large data management techniques, large scale optimization method, etc. Therefore, demand-response (DR) programs can be one of the prosperous solutions to accommodate part of the increasing demand for load balancing services which is brought about by the high penetration of intermittent renewable energies in power systems. This dissertation studies different aspects of the DR programs that utilized the thermostatically controlled loads (TCLs) to provide load balancing services. The importance of TCLs among the other loads lie on their flexibility in power consumption pattern while the customer/end-user comfort is not (or minimally) impacted. Chapter 2 discussed a previously presented direct load control (DLC) to control the power consumption of aggregated TCLs. The DLC method performs a power tracking control and based on central approach where a central controller broadcasts the control command to the dispersed TCLs to toggle them on/off. The central controller receives measurement feedback from the TCLs once per couple of minutes to run a successful forecast process. The performance evaluation criteria to evaluate the load balancing service provided by the TCLs are presented. The results are discussed under different scenarios and situation. The numerical results show the proper performance of the DLC method. This DLC method is used as the control method in all the studies in this dissertation. Chapter 3 presents performance improvements for the original method in Chapter 2 by communicating two more pieces of information called forecast parameters (FPs). Communicating improves the forecast process in the DLC and hence, both performance accuracy and the amount of tear-and-wear imposed on the TCLs. Chapter 4 formulates a stochastic

    2013-12-19

    The mission of the Earth System Grid Federation (ESGF) is to provide the worldwide climate-research community with access to the data, information, model codes, analysis tools, and intercomparison capabilities required to make sense of enormous climate data sets. Its specific goals are to (1) provide an easy-to-use and secure web-based data access environment for data sets; (2) add value to individual data sets by presenting them in the context of other data sets and tools for comparative analysis; (3) address the specific requirements of participating organizations with respect to bandwidth, access restrictions, and replication; (4) ensure that the data are readily accessible through the analysis and visualization tools used by the climate research community; and (5) transfer infrastructure advances to other domain areas. For the ESGF, the U.S. Department of Energy’s (DOE’s) Earth System Grid Center for Enabling Technologies (ESG-CET) team has led international development and delivered a production environment for managing and accessing ultra-scale climate data. This production environment includes multiple national and international climate projects (such as the Community Earth System Model and the Coupled Model Intercomparison Project), ocean model data (such as the Parallel Ocean Program), observation data (Atmospheric Radiation Measurement Best Estimate, Carbon Dioxide Information and Analysis Center, Atmospheric Infrared Sounder, etc.), and analysis and visualization tools, all serving a diverse user community. These data holdings and services are distributed across multiple ESG-CET sites (such as ANL, LANL, LBNL/NERSC, LLNL/PCMDI, NCAR, and ORNL) and at unfunded partner sites, such as the Australian National University National Computational Infrastructure, the British Atmospheric Data Centre, the National Oceanic and Atmospheric Administration Geophysical Fluid Dynamics Laboratory, the Max Planck Institute for Meteorology, the German Climate Computing

  3. Opportunities for ice storage to provide ancillary services to power grids incorporating wind turbine generation

    Finley, Christopher

    Power generation using wind turbines increases the electrical system balancing, regulation and ramp rate requirements due to the minute to minute variability in wind speed and the difficulty in accurately forecasting wind speeds. The addition of thermal energy storage, such as ice storage, to a building's space cooling equipment increases the operational flexibility of the equipment by allowing the owner to choose when the chiller is run. The ability of the building owner to increase the power demand from the chiller (e.g. make ice) or to decrease the power demand (e.g. melt ice) to provide electrical system ancillary services was evaluated.

  8. Development and Operation of the D-Grid Infrastructure

    Fieseler, Thomas; Gűrich, Wolfgang

    D-Grid is the German national grid initiative, granted by the German Federal Ministry of Education and Research. In this paper we present the Core D-Grid which acts as a condensation nucleus to build a production grid and the latest developments of the infrastructure. The main difference compared to other international grid initiatives is the support of three middleware systems, namely LCG/gLite, Globus, and UNICORE for compute resources. Storage resources are connected via SRM/dCache and OGSA-DAI. In contrast to homogeneous communities, the partners in Core D-Grid have different missions and backgrounds (computing centres, universities, research centres), providing heterogeneous hardware from single processors to high performance supercomputing systems with different operating systems. We present methods to integrate these resources and services for the DGrid infrastructure like a point of information, centralized user and virtual organization management, resource registration, software provision, and policies for the implementation (firewalls, certificates, user mapping).

    2014-12-01

    Full Text Available Contemporary universities services quality level concerns mainly the education efficiency evaluation that results from the learning outcomes realization and innovative features of the teaching programs that differ universities offers. Technical universities attention is focused on ministerial requirements fulfillment which are strictly concentrated on the students skills obtaining in the relation to the employers’ market. The university services quality analysis ignores common expectations of students and candidates for students related to the technical or functional quality, such as university facilities and administrative workers empathy. The aim of this study is to identify the expectations of both students and candidates for studies at technical universities, what allows to identify university services quality level and areas needs improvement in terms of not only the educational services but also technical university facilities. Results show significant importance of the all examined service quality aspects in the context of expectations of candidates and students’ perception. Research findings allow not only to identify the technical university services quality, but also to support the university development within the scientific research process assistance.

    2013-01-01

    In the Wordwide LHC Computing Grid (WLCG) project the Tier centres are of paramount importance for storing and accessing experiment data and for running the batch jobs necessary for experiment production activities. Although Tier2 sites provide a significant fraction of the resources a non-availability of resources at the Tier0 or the Tier1s can seriously harm not only WLCG Operations but also the experiments' workflow and the storage of LHC data which are very expensive to reproduce. This is why availability requirements for these sites are high and committed in the WLCG Memorandum of Understanding (MoU). In this talk we describe the workflow of GGUS ALARMs, the only 24/7 mechanism available to LHC experiment experts for reporting to the Tier0 or the Tier1s problems with their Critical Services. Conclusions and experience gained from the detailed drills performed in each such ALARM for the last 4 years are explained and the shift with time of Type of Problems met.

    2007-06-01

    Today's global communities of users expect quality of service from distributed Grid systems equivalent to that their local data centers. This must be coupled to ubiquitous access to the ensemble of processing and storage resources across multiple Grid infrastructures. We are still facing significant challenges in meeting these expectations, especially in the underlying security, a sustainable and successful economic model, and smoothing the boundaries between administrative and technical domains. Using the Open Science Grid as an example, I examine the status and challenges of Grids operating in production today.

  6. THE PERFORMANCE OF SERVQUAL TO MEASURE SERVICE QUALITY IN PRIVATE UNIVERSITY

    Leonnard

    2018-03-01

    Full Text Available The increasing number of educational services has caused a high competition in this industry. In Indonesia, the number of private universities is the highest compared to state universities and other forms of higher education institutions. Ability to predict factors that are important in providing educational services to achieve student satisfaction and make them loyal to the university is highly necessary. In this study, we investigated the main factors of service quality that affect student satisfaction and loyalty by collecting data from 319 students from London School of Public Relation in Jakarta. Structural equation modeling (SEM was employed to analyze the data through AMOS 24 statistical package. The findings indicated that the main factors influencing student satisfaction in private university are tangible and reliability consisting of: 1 comfortable lecture rooms, 2 adequate library facilities, 3 neat staff appearance, 4 non-discriminatory treatments provided by staff and lecturers, 5 high ability and knowledge provided by staffs and lecturers, and 6 appropriate academic services provided by the university. Student satisfaction with these factors would indirectly lead to loyalty to the university. Finally, service quality measurement through SERVQUAL was redundant as a model to measure the effect of service quality in educational service.

Delivery of educational and research services through these university websites including information, interaction, transaction, and Integration were investigated using a checklist. The data were then analyzed by means of descriptive statistics and using SPSS software. Results: Level of educational and research services by websites of the medical universities type I and II was evaluated medium as 1.99 and 1.89, respectively. All the universities gained a mean score of 1 out of 3 in terms of integration of educational and research services. Conclusions: Results of the study indicated that Iranian universities have passed information and interaction stages, but they have not made much progress in transaction and integration stages. Failure to adapt to e-government in Iranian medical universities in which limiting factors such as users’ e-literacy, access to the internet and ICT infrastructure are not so crucial as in other organizations, suggest that e-government realization goes beyond technical challenges.

    2017-02-01

    ENEA Consulting published the results of a study on urban micro-grids conducted in partnership with the Group ADP, the Group Caisse des Depots, ENEDIS, Omexom, Total and the Tuck Foundation. This study offers a vision of the definition of an urban micro-grid, the value brought by a micro-grid in different contexts based on real case studies, and the upcoming challenges that micro-grid stakeholders will face (regulation, business models, technology). The electric production and distribution system, as the backbone of an increasingly urbanized and energy dependent society, is urged to shift towards a more resilient, efficient and environment-friendly infrastructure. Decentralisation of electricity production into densely populated areas is a promising opportunity to achieve this transition. A micro-grid enhances local production through clustering electricity producers and consumers within a delimited electricity network; it has the ability to disconnect from the main grid for a limited period of time, offering an energy security service to its customers during grid outages for example. However: The islanding capability is an inherent feature of the micro-grid concept that leads to a significant premium on electricity cost, especially in a system highly reliant on intermittent electricity production. In this case, a smart grid, with local energy production and no islanding capability, can be customized to meet relevant sustainability and cost savings goals at lower costs For industrials, urban micro-grids can be economically profitable in presence of high share of reliable energy production and thermal energy demand micro-grids face strong regulatory challenges that should be overcome for further development Whether islanding is or is not implemented into the system, end-user demand for a greener, more local, cheaper and more reliable energy, as well as additional services to the grid, are strong drivers for local production and consumption. In some specific cases

  14. The role of universities in preparing graduates to use software in the financial services workplace

    Tickle, Leonie; Kyng, Tim; Wood, Leigh N.

    2014-02-01

    The role of universities in preparing students to use spreadsheet and other technical software in the financial services workplace has been investigated through surveys of university graduates, university academics, and employers. It is found that graduates are less skilled users of software than employers would like, due at least in part to a lack of structured formal training opportunities in the workplace, and a lack of targeted, coherent learning opportunities at university. The widespread and heavy use of software in the workplace means that there is significant potential for productivity gains if universities and employers address these issues.

    2018-06-01

    Full Text Available Based on the perspective of knowledge transfer and the technology acceptance model (TAM, this paper constructs a university technology transfer sustainable development model that considers the inventor’s technology service from the perspective of the long-term cooperation of enterprise, and analyzes the mediating effect of the inventor’s technology service on university technology transfer sustainability. By using 270 questionnaires as survey data, it is found that the availability of an inventor’s technology service has a significant positive impact on the attitude tendency and practice tendency of enterprise long-term technological cooperation; enterprise technology absorption capacity and trust between a university and an enterprise also have significant influence on an inventor’s technical service availability. Therefore, the inventor’s technology service acts as a mediator in the relationship between university technology transfer sustainability and influence factors. Universities ought to establish the technology transfer model, which focuses on the inventor’s tacit knowledge transfer service, and promotes the sustainable development of the university.

  15. A Web Service Tool (SOAR) for the Dynamic Generation of L1 Grids of Coincident AIRS, AMSU and MODIS Satellite Sounding Radiance Data for Climate Studies

    Halem, M.; Yesha, Y.; Tilmes, C.; Chapman, D.; Goldberg, M.; Zhou, L.

    2007-05-01

    Three decades of Earth remote sensing from NASA, NOAA and DOD operational and research satellites carrying successive generations of improved atmospheric sounder instruments have resulted in petabytes of radiance data with varying spatial and spectral resolutions being stored at different data archives in various data formats by the respective agencies. This evolution of sounders and the diversities of these archived data sets have led to data processing obstacles limiting the science community from readily accessing and analyzing such long-term climate data records. We address this problem by the development of a web based Service Oriented Atmospheric Radiance (SOAR) system built on the SOA paradigm that makes it practical for the science community to dynamically access, manipulate and generate long term records of L1 pre-gridded sounding radiances of coincident multi-sensor data for regions specified according to user chosen criteria. SOAR employs a modification of the standard Client Server interactions that allows users to represent themselves directly to the Process Server through their own web browsers. The browser uses AJAX to request Javascript libraries and DHTML interfaces that define the possible client interactions and communicates the SOAP messages to the Process server allowing for dynamic web dialogs with the user to take place on the fly. The Process Server is also connected to an underlying high performance compute cluster and storage system which provides much of the data processing capabilities required to service the client requests. The compute cluster employs optical communications to NOAA and NASA for accessing the data and under the governance of the Process Server invokes algorithms for on-demand spatial, temporal, and spectral gridding. Scientists can choose from a variety of statistical averaging techniques for compositing satellite observed sounder radiances from the AIRS, AMSU or MODIS instruments to form spatial-temporal grids for

Customer Satisfaction is measured through 4 questions. The data then are processed by SPSS. The results showed that the students preferred to tangible quality improvement than intangible aspect.

  17. The CMS integration grid testbed

    Graham, Gregory E.

    2004-08-26

    The CMS Integration Grid Testbed (IGT) comprises USCMS Tier-1 and Tier-2 hardware at the following sites: the California Institute of Technology, Fermi National Accelerator Laboratory, the University of California at San Diego, and the University of Florida at Gainesville. The IGT runs jobs using the Globus Toolkit with a DAGMan and Condor-G front end. The virtual organization (VO) is managed using VO management scripts from the European Data Grid (EDG). Gridwide monitoring is accomplished using local tools such as Ganglia interfaced into the Globus Metadata Directory Service (MDS) and the agent based Mona Lisa. Domain specific software is packaged and installed using the Distribution After Release (DAR) tool of CMS, while middleware under the auspices of the Virtual Data Toolkit (VDT) is distributed using Pacman. During a continuous two month span in Fall of 2002, over 1 million official CMS GEANT based Monte Carlo events were generated and returned to CERN for analysis while being demonstrated at SC2002. In this paper, we describe the process that led to one of the world's first continuously available, functioning grids.

  18. Service-learning from the views of university teachers: a qualitative study based on focus groups.

    Shek, Daniel T L; Chan, Stephen C F

    2013-01-01

    Under the New Undergraduate Curriculum at The Hong Kong Polytechnic University (PolyU), students are required to take a 3-credit subject to fulfill service-learning requirements. To understand the views of teachers regarding service-learning, five focus group interviews (n=33) are conducted to examine the perceived characteristics and myths of service-learning as well as colleagues' views on the policy at PolyU. Results showed that most informants are aware of service-learning and have seen its benefits to both students and teachers. Most informants also possess positive views about service-learning. Nevertheless, in terms of service-learning at PolyU, three different groups of views on service-learning are observed, namely, positive, negative, and mixed views. This paper also discusses teachers' views on the anticipated difficulties of service-learning implementation and the ways, by which to promote the subject in the PolyU context.

    2017-01-01

    We modeled design factors influencing the intent to use a university mental health service. Between November 2012 and October 2014, 909 undergraduates participated. Using a discrete choice experiment, participants chose between hypothetical campus mental health services. Latent class analysis identified three segments. A Psychological/Psychiatric Service segment (45.5%) was most likely to contact campus health services delivered by psychologists or psychiatrists. An Alternative Service segment (39.3%) preferred to talk to peer-counselors who had experienced mental health problems. A Hesitant segment (15.2%) reported greater distress but seemed less intent on seeking help. They preferred services delivered by psychologists or psychiatrists. Simulations predicted that, rather than waiting for standard counseling, the Alternative Service segment would prefer immediate access to E-Mental health. The Usual Care and Hesitant segments would wait 6 months for standard counseling. E-Mental Health options could engage students who may not wait for standard services.

  20. Students’ experiences of university social responsibility and perceptions of satisfaction and quality of service

    2015-03-01

    Full Text Available The principal aim of this paper is to identify the factors that define students’ perceptions of university social responsibility (USR in a Spanish university, and analyse the impact of that view on their perceptions of satisfaction and quality of service. Particularly, it is hypothesized that the overall perception of university social responsibility has a positive effect on students’ experiences of satisfaction, partially mediated by the assessment regarding the quality of university services. In doing that, a self-report study was conducted with a total sample of 400 undergraduate students of the University of León, in Spain. Structural equation modeling with PLS was used to test the students’ overall perception of USR in order to achieve higher standards of quality of service and satisfaction. Results supported a structure of six factors explaining students’ views regarding university social responsibility, of which only internal management affects the overall perception. Likewise, quality of service and satisfaction are strongly correlated among them. Implications of these findings for marketing in university settings are discussed.

Questionnaire and face-to-face interviews were used in the collection of data. The hypotheses were tested using descriptive statistics. The study discovered among other things that with the inauguration of the SERVICOM Charter by the Federal Government of Nigeria, the Management of Nnamdi Azikiwe University Teaching Hospital Nnewi identified key areas that required re-evaluation and attention based on the submissions of every service unit and department, after an analysis of the Strengths, Weaknesses, Opportunities and Threats (SWOT of each of the service areas. A pre-SERVICOM Charter workshop which was supervised by the Federal Government was held in the various institutions nationwide to enable care providers enumerate their current service capacity and identify their impediments. In the light of the foregoing, some of the recommendations proffered are that the SERVICOM Charter project should be sustained and supervision and control of the SERVICOM Charter project should be intensified in order to ensure that the Nigerian factor of service-fatigue would not supervene in care delivery in the near future.

    The Open Science Grid is a recognized key component of the US national cyber-infrastructure enabling scientific discovery through advanced high throughput computing. The principles and techniques that underlie the Open Science Grid can also be applied to Campus Grids since many of the requirements are the same, even if the implementation technologies differ. We find five requirements for a campus grid: trust relationships, job submission, resource independence, accounting, and data management. The Holland Computing Center's campus grid at the University of Nebraska-Lincoln was designed to fulfill the requirements of a campus grid. A bridging daemon was designed to bring non-Condor clusters into a grid managed by Condor. Condor features which make it possible to bridge Condor sites into a multi-campus grid have been exploited at the Holland Computing Center as well.

  5. University psychiatry in Italy: organisation and integration of university clinics and the National Health Service

    Pier Maria Furlan

    2013-09-01

    Full Text Available INTRODUCTION: In the Italian psychiatric system, community-based care has become increasingly important and widespread since the national reform of 1978. This report aims to provide an overview of the involvement of university medical schools in this process, considering their responsibility for teaching and training specialist practitioners and professionals. METHODS: The study was carried out between early 2010 and February 2011. An 18-items, self-administered, questionnaire was designed to investigate the number of faculty members that are responsible both for running a clinical ward and for providing community-based healthcare. RESULTS: Nine out of 53 faculty members (17% manage a Mental Health Department, 9 (17% manage a University Department, and 2 (3.8% manage both types of department. Less than half of the teachers have full responsibility (hospital and community; however the percentage reaches 73.2% if we include the hospital wards open to the community emergencies. The remaining 26.8% have no responsibility for community psychiatry. Moreover there were undoubtedly still too many universities with specialisation schools that are without an appropriate network of facilities enabling them to offer complex psychiatric training. DISCUSSION: As expected, there were several types of healthcare management that were not uniformly distributed throughout Italy and there were also marked differences between mental health care provision in the North, Centre, and South of Italy. The university involvement in clinical responsibility was great, but at the management level there was a lack of equality in terms of clinical care, which risks being reflected also on the institutional functions of teaching and research.

    In recognition of the fact that billions of people in the developing world do not have access to clean energies, the United Nations launched the Sustainable Energy for All Initiative to achieve universal energy access by 2030. Although electricity grid extension remains the most prevalent way of providing access, it is now recognized that the central grid is unlikely to reach many remote areas in the near future. At the same time, individual solutions like solar home systems tend to provide very limited services to consumers. Mini-grids offer an alternative by combining the benefits of a grid-

    2010-05-01

    Modelling noise propagation using Grid Resources. Progress within GDI-Grid. GDI-Grid (english: SDI-Grid) is a research project funded by the German Ministry for Science and Education (BMBF). It aims at bridging the gaps between OGC Web Services (OWS) and Grid infrastructures and identifying the potential of utilizing the superior storage capacities and computational power of grid infrastructures for geospatial applications while keeping the well-known service interfaces specified by the OGC. The project considers all major OGC webservice interfaces for Web Mapping (WMS), Feature access (Web Feature Service), Coverage access (Web Coverage Service) and processing (Web Processing Service). The major challenge within GDI-Grid is the harmonization of diverging standards as defined by standardization bodies for Grid computing and spatial information exchange. The project started in 2007 and will continue until June 2010. The concept for the gridification of OWS developed by lat/lon GmbH and the Department of Geography of the University of Bonn is applied to three real-world scenarios in order to check its practicability: a flood simulation, a scenario for emergency routing and a noise propagation simulation. The latter scenario is addressed by the Stapelfeldt Ingenieurgesellschaft mbH located in Dortmund adapting their LimA software to utilize grid resources. Noise mapping of e.g. traffic noise in urban agglomerates and along major trunk roads is a reoccurring demand of the EU Noise Directive. Input data requires road net and traffic, terrain, buildings and noise protection screens as well as population distribution. Noise impact levels are generally calculated in 10 m grid and along relevant building facades. For each receiver position sources within a typical range of 2000 m are split down into small segments, depending on local geometry. For each of the segments propagation analysis includes diffraction effects caused by all obstacles on the path of sound propagation

  8. A Universal Design Approach to Government Service Delivery: The Case of ChileAtiende.

    Sandoval, Leonardo

    2016-01-01

    A common challenge for government administrations that aim to improve the delivery of information and services to citizens is to go beyond a government-centred approach. By focusing on citizens and the needs of a wide range of citizens, Universal Design (UD) can help to increase the effectiveness, efficiency and satisfaction of government services. This paper examines the case of an internationally recognised Chilean government service delivery programme inspired by UD principles known as ChileAtiende ("ChileService").

    Electricity generated by Hydropower Plants (HPPs) contributes a considerable portion of bulk electricity generation and delivers it with a low carbon footprint. In fact, HPP electricity generation provides the largest share from renewable energy resources, which includes solar and wind energy. The increasing penetration of wind and solar penetration leads to a lowered inertia in the grid and hence poses stability challenges. In recent years, breakthrough in energy storage technologies have demonstrated the economic and technical feasibility of extensive deployments in power grids. Multiple ROR HPPs if integrated with scalable, multi time-step energy storage so that the total output can be controlled. Although, the size of a single energy storage is far smaller than that of a typical reservoir, cohesively managing multiple sets of energy storage distributed in different locations is proposed. The ratings of storages and multiple ROR HPPs approximately equals the rating of a large, conventional HPP. The challenges associated with the system architecture and operation are described. Energy storage technologies such as supercapacitors, flywheels, batteries etc. can function as a dispatchable synthetic reservoir with a scalable size of energy storage will be integrated. Supercapacitors, flywheels, and battery are chosen to provide fast, medium, and slow responses to support grid requirements. Various dynamic and transient power grid conditions are simulated and performances of integrated ROR HPPs with energy storage is provided. The end goal of this research is to investigate the inertial equivalence of a large, conventional HPP with a unique set of multiple ROR HPPs and optimally rated energy storage systems.

  13. Blueprint and First Experiences Bridging Hardware Virtualization and Global Grids for Advanced Scientific Computing: Designing and Building a Global Edge Services Framework (ESF) for OSG, EGEE, and LCG

    Rana, A S; Vaniachine, A; Wurthwein, F; Foster, I; Sotomayor, B; Freeman, T

    2006-01-01

    We report on first experiences with building and operating an edge services framework (ESF) based on Xen virtual machines instantiated via the workspace service in Globus toolkit, and developed as a joint project between EGEE, LCG, and OSG. Many computing facilities are architected with their compute and storage clusters behind firewalls. Edge services (ES) are instantiated on a small set of gateways to provide access to these clusters via standard grid interfaces. Experience on EGEE, LCG, and OSG has shown that at least two issues are of critical importance when designing an infrastructure in support of ES. The first concerns ES configuration. It is impractical to assume that each virtual organization (VO) using a facility will employ the same ES configuration, or that different configurations will coexist easily. Even within a VO, it should be possible to run different versions of the same ES simultaneously. The second issue concerns resource allocation: it is essential that an ESF be able to effectively gu...

    2018-03-01

    Residential satisfaction of university dormitories serve as one of the significant aspects in the framework of sustainability in higher education. This research investigated the quality of dormitory services in Andalas University Dormitory based on student’s satisfaction. According to management residential, the enrollment of residential student has increased gradually in Andalas University. In 2016, capacity of residential student is 1686, but only 1081 students can stay at dormitory because some rooms in bad condition. There are a lot of problems and complaints regarding dormitory’s service quality i.e water problems, leaky rooms and bathrooms, cleanliness and inadequate facilities in residential college. In addition, there are 20% of last year student’s residential check out before the time of contract runs out. The aim of this research are understanding the level of GAP exists between expectation and perception students’ residential in the content of service quality and evaluating the improvement priority services using Importance Performance Analysis. This study is measuring service quality by using Responsiveness, Assurance, Empathy, Reliability and Tangible dimension. A negative GAP indicates that the actual services are than what was expected and the GAP is highlighted area for improvement. Based on IPA, management should improve this following dimension services : responsiveness, tangible and assurance dimension.

    Obiechina, G O; Ekenedo, G O

    2013-01-01

    Most university health services have extensive health infrastructures, for the provision of effective and efficient health services to the students. In this study, we have tried to determine student's perception of factors affecting their utilization. To determine students' perception of health care services provided in a tertiary institution and assess students' attitude towards utilization. Simple random sampling technique was used to select 540 respondents, comprising of 390 males and 150 females. A structured and self-administered questionnaire was the instrument used to collect data for the study, while data collected was analyzed using descriptive statistics of frequency count and percentage. High cost of drugs (72.0%), non availability of essential drugs (54.8%), time spent waiting for treatment (67.2%), inadequate referral services (81.7%), and satisfaction with services (60.6%) were considered by the respondents as factors affecting the utilization of university health services. Students-medical staff relationship and accessibility to health facility (77.6% and 74.3% respectively) were, however, not considered as factors that affect utilization of university health services. It is recommended that to improve utilization and cost of care, government should make necessary efforts to incorporate tertiary institution into National Health Insurance scheme so that students above the age of 18 years can benefit from free treatment.

    2012-07-01

    Full Text Available This paper examines pre-service English teachers’ beliefs towards grammar studying at two Turkish Universities. A total of 90 pre-service English teachers, 57 of whom were studying at Muğla University and 33 of whom were studying at Onsekiz Mart University in Turkey, were involved in this study. The research participants completed two questionnaires. The aim of this paper is to look into pre-service English teachers’ beliefs towards grammar and its teaching as well as their knowledge on the metalanguage of grammar. The findings reveal that although a great majority of the participants favour the use of metalanguage in teaching grammar, and support the deductive grammar teaching practises, they themselves still have serious problems even with the most basic grammatical terminology.

  18. The Grid

    Klotz, Wolf-Dieter

    2005-01-01

    Grid technology is widely emerging. Grid computing, most simply stated, is distributed computing taken to the next evolutionary level. The goal is to create the illusion of a simple, robust yet large and powerful self managing virtual computer out of a large collection of connected heterogeneous systems sharing various combinations of resources. This talk will give a short history how, out of lessons learned from the Internet, the vision of Grids was born. Then the extensible anatomy of a Grid architecture will be discussed. The talk will end by presenting a selection of major Grid projects in Europe and US and if time permits a short on-line demonstration.

    Highly efficient direct current (DC) appliances have the potential to dramatically increase the affordability of off-grid solar power systems used for rural electrification in developing countries by reducing the size of the systems required. For example, the combined power requirement of a highly efficient color TV, four DC light emitting diode (LED) lamps, a mobile phone charger, and a radio is approximately 18 watts and can be supported by a small solar power system (at 27 watts peak, Wp). Price declines and efficiency advances in LED technology are already enabling rapidly increased use of small off-grid lighting systems in Africa and Asia. Similar progress is also possible for larger household-scale solar home systems that power appliances such as lights, TVs, fans, radios, and mobile phones. When super-efficient appliances are used, the total cost of solar home systems and their associated appliances can be reduced by as much as 50%. The results vary according to the appliances used with the system. These findings have critical relevance for efforts to provide modern energy services to the 1.2 billion people worldwide without access to the electrical grid and one billion more with unreliable access. However, policy and market support are needed to realize rapid adoption of super-efficient appliances.

  20. Applied research and service activities at the University of Missouri Research Reactor Facility (MURR)

    Alger, D.M.

    1987-01-01

    The University Of Missouri operates MURR to provide an intense source of neutron and gamma radiation for research and applications by experimenters from its four campuses and by experimenters from other universities, government and industry. The 10 MW reactor, which has been operating an average of 155 hours per week for the past eight years, produces thermal neutron fluxes up to 6-7x10 14 n/cm 2 -s in the central flux trap and beamport source fluxes of up to 1.2x10 14 n/cm 2 -s. The mission of the reactor facility, to promote research, education and service, is the same as the overall mission of the university and therefore, applied research and service supported by industrial firms have been welcomed. The university recognized after a few years of reactor operation that in order to build utilization, it would be necessary to develop in-house research programs including people, equipment and activity so that potential users could more easily and quickly obtain the results needed. Nine research areas have been developed to create a broadly based program to support the level of activity needed to justify the cost of operating the facility. Applied research and service generate financial support for about one-half of the annual budget. The applied and service programs provide strong motivation for university/industry association in addition to the income generated. (author)

    2016-03-01

    This article summarizes the experience with the development of clinical pharmacy services in the Ghent University Hospital in Belgium. Implementation of clinical pharmacy services in Belgian hospitals has not been evident because these activities were initially not structurally financed. The aim is to describe the strengths and weaknesses of the clinical pharmacy development process, and the milestones that enhanced the progress. Furthermore, the organisation of clinical pharmacy in the Ghent University Hospital is explained, including back- and front-office activities, seamless pharmaceutical care and medication safety improvement. Some working methods, procedures and tools are explained for different clinical pharmacy services. In particular, the clinical pharmacy projects for geriatric patients as well as the preparation of clinical pharmacy services for the accreditation process are explained. We also reflect on the organisation model and the future development of clinical pharmacy, taking into consideration facilitators and potential barriers.

  2. Introduction of a university-based counselling service for older adults.

    Bhar, Sunil S; Silver, Mark

    2014-03-01

    Despite the growing number of older adults in Australia, many do not access counselling, partly because of the lack of trained mental health professionals for older people. This paper describes an innovative solution for providing counselling services to older adults, and geropsychology training to postgraduate psychology students. A university-based counselling clinic for older adults was described – an outreach service for older adults living in the community or in residential aged care facilities in metropolitan Melbourne, Australia. Over its first 13 months, the clinic provided a total of 266 sessions of counselling to 57 clients (41 living in residential aged care), and involved six postgraduate students. This paper describes the potential benefits of the clinic for clients and students and the resources needed to support this model of service delivery. Thus, it provides a blueprint for other universities for developing similar services for older adults.

  7. Current Grid operation and future role of the Grid

    Smirnova, O.

    2012-12-01

    Grid-like technologies and approaches became an integral part of HEP experiments. Some other scientific communities also use similar technologies for data-intensive computations. The distinct feature of Grid computing is the ability to federate heterogeneous resources of different ownership into a seamless infrastructure, accessible via a single log-on. Like other infrastructures of similar nature, Grid functioning requires not only technologically sound basis, but also reliable operation procedures, monitoring and accounting. The two aspects, technological and operational, are closely related: weaker is the technology, more burden is on operations, and other way around. As of today, Grid technologies are still evolving: at CERN alone, every LHC experiment uses an own Grid-like system. This inevitably creates a heavy load on operations. Infrastructure maintenance, monitoring and incident response are done on several levels, from local system administrators to large international organisations, involving massive human effort worldwide. The necessity to commit substantial resources is one of the obstacles faced by smaller research communities when moving computing to the Grid. Moreover, most current Grid solutions were developed under significant influence of HEP use cases, and thus need additional effort to adapt them to other applications. Reluctance of many non-HEP researchers to use Grid negatively affects the outlook for national Grid organisations, which strive to provide multi-science services. We started from the situation where Grid organisations were fused with HEP laboratories and national HEP research programmes; we hope to move towards the world where Grid will ultimately reach the status of generic public computing and storage service provider and permanent national and international Grid infrastructures will be established. How far will we be able to advance along this path, depends on us. If no standardisation and convergence efforts will take place

    Abstract Public health insurance coverage for preventive care in young adults is incomplete in Korea. Few studies have focused on young adults’ socioeconomic disparities in preventive care utilization. We aimed to explore household income disparities in the use of different types of health screening services among university students in Korea. This cross-sectional study used a web-based self-administered survey of students at a university in Korea from January to February 2013. To examine the associations between household income levels and health screening service use within the past 2 years, odds ratios (ORs) and 95% confidence intervals (CIs) were estimated using logistic regression with adjustment for various covariables. Of 2479 participants, 45.5% reported using health screening services within 2 years (university-provided screening 32.9%, private sector screening 16.7%, and both 4.1%). Household income levels were not significantly associated with overall rates of health screening service use with a multivariable-adjusted OR (95% CI) in the lowest versus highest income group of 1.12 (0.87–1.45, Ptrend = 0.35). However, we found significantly different associations in specific types of utilized screening services by household income levels. The multivariable-adjusted OR (95% CI) of university-provided health screening service use in the lowest versus highest income level was 1.74 (1.30–2.34; Ptrend income level was 0.45 (0.31–0.66; Ptrend income groups among university students in Korea, although overall rates of health screening service use were similar across income levels. Low-income students were more likely to use university-provided health screening services, and less likely to use private sector screening services. To ensure appropriate preventive care delivery for young adults and to address disparities in disadvantaged groups, the expansion of medical insurance coverage for preventive health care, establishment of a usual source of

  16. Are social franchises contributing to universal access to reproductive health services in low-income countries?

    Sundari Ravindran, T K; Fonn, Sharon

    2011-11-01

    A social franchise in health is a network of for-profit private health practitioners linked through contracts to provide socially beneficial services under a common brand. The early 21st century has seen considerable donor enthusiasm for promoting social franchises for the provision of reproductive health services. Based on a compendium of descriptive information on 45 clinical social franchises, located in 27 countries of Africa, Asia and Latin America, this paper examines their contribution to universal access to comprehensive reproductive health services. It finds that these franchises have not widened the range of reproductive health services, but have mainly focused on contraceptive services, and to a lesser extent, maternal health care and abortion. In many instances, coverage had not been extended to new areas. Measures taken to ensure sustainability ran counter to the objective of access for low-income groups. In almost two-thirds of the franchises, the full cost of all services had to be paid out of pocket and was unaffordable for low-income women. While standards and protocols for quality assurance were in place in all franchises, evidence on adherence to these was limited. Informal interviews with patients indicated satisfaction with services. However, factors such as difficulties in recruiting franchisees and significant attrition, franchisees' inability to attend training programmes, use of lay health workers to deliver services without support or supervision, and logistical problems with applying quality assurance tools, all raise concerns. The contribution of social franchises to universal access to reproductive health services appears to be uncertain. Continued investment in them for the provision of reproductive health services does not appear to be justified until and unless further evidence of their value is forthcoming.

    Fermilab supports a scientific program that includes experiments and scientists located across the globe. In order to better serve this community, Fermilab has placed its production computer resources in a Campus Grid infrastructure called 'FermiGrid'. The FermiGrid infrastructure allows the large experiments at Fermilab to have priority access to their own resources, enables sharing of these resources in an opportunistic fashion, and movement of work (jobs, data) between the Campus Grid and National Grids such as Open Science Grid and the WLCG. FermiGrid resources support multiple Virtual Organizations (VOs), including VOs from the Open Science Grid (OSG), EGEE and the Worldwide LHC Computing Grid Collaboration (WLCG). Fermilab also makes leading contributions to the Open Science Grid in the areas of accounting, batch computing, grid security, job management, resource selection, site infrastructure, storage management, and VO services. Through the FermiGrid interfaces, authenticated and authorized VOs and individuals may access our core grid services, the 10,000+ Fermilab resident CPUs, near-petabyte (including CMS) online disk pools and the multi-petabyte Fermilab Mass Storage System. These core grid services include a site wide Globus gatekeeper, VO management services for several VOs, Fermilab site authorization services, grid user mapping services, as well as job accounting and monitoring, resource selection and data movement services. Access to these services is via standard and well-supported grid interfaces. We will report on the user experience of using the FermiGrid campus infrastructure interfaced to a national cyberinfrastructure--the successes and the problems

    The German Federal Government aims to reach one million electric vehicles in 2020 and up to five million by 2030 under its National Electromobility Development Plan. The integration of the necessary charging infrastructure in the distribution grid is considered in many research approaches by regarding charging time slots controlled by information and communications technology (ICT). In this approach, strategies for reactive power management and gridsupporting functions in medium voltage networks through the integration of large charging stations such as those in parking garages and public parking lots are considered. An urban distribution network in 2030 is modelled to evaluate different centralized and decentralized reactive power control schemes. (orig.)

  20. OGC and Grid Interoperability in enviroGRIDS Project

    Gorgan, Dorian; Rodila, Denisa; Bacu, Victor; Giuliani, Gregory; Ray, Nicolas

    2010-05-01

    EnviroGRIDS (Black Sea Catchment Observation and Assessment System supporting Sustainable Development) [1] is a 4-years FP7 Project aiming to address the subjects of ecologically unsustainable development and inadequate resource management. The project develops a Spatial Data Infrastructure of the Black Sea Catchment region. The geospatial technologies offer very specialized functionality for Earth Science oriented applications as well as the Grid oriented technology that is able to support distributed and parallel processing. One challenge of the enviroGRIDS project is the interoperability between geospatial and Grid infrastructures by providing the basic and the extended features of the both technologies. The geospatial interoperability technology has been promoted as a way of dealing with large volumes of geospatial data in distributed environments through the development of interoperable Web service specifications proposed by the Open Geospatial Consortium (OGC), with applications spread across multiple fields but especially in Earth observation research. Due to the huge volumes of data available in the geospatial domain and the additional introduced issues (data management, secure data transfer, data distribution and data computation), the need for an infrastructure capable to manage all those problems becomes an important aspect. The Grid promotes and facilitates the secure interoperations of geospatial heterogeneous distributed data within a distributed environment, the creation and management of large distributed computational jobs and assures a security level for communication and transfer of messages based on certificates. This presentation analysis and discusses the most significant use cases for enabling the OGC Web services interoperability with the Grid environment and focuses on the description and implementation of the most promising one. In these use cases we give a special attention to issues such as: the relations between computational grid and

    2015-01-01

    In developed countries including Japan, malignant tumor (cancer), heart disease and cerebral apoplexy are major causes of death, but infectious diseases are still responsible for a high number of deaths in developing countries, especially among children aged less than 5 years. World Health Statistics published by WHO reports a high percentage of mortality from infectious diseases in children, and many of these diseases may be subject to transmission across borders and could possibly invade Japan.  Given this situation, the Ministry of Education, Culture, Sports, Science and Technology (MEXT) of Japan initiated Phase I of the Program of Founding Research Centers for Emerging and Reemerging Infectious Disease, which ran from FY 2005 to 2009, and involved 8 Japanese universities and 2 research centers. The program was established for the following purposes: 1) creation of a domestic research structure to promote the accumulation of fundamental knowledge about infectious diseases, 2) establishment of 13 overseas research collaboration centers in 8 countries at high risk of emerging and reemerging infections and at which Japanese researchers are stationed and conduct research in partnership with overseas instructors, 3) development of a network among domestic and overseas research centers, and 4) development of human resources.  The program was controlled under MEXT and managed by the RIKEN Center of Research Network for Infectious Diseases (Riken CRNID). Phase II of the program was set up as the Japan Initiative for Global Research Network on Infectious Diseases (J-GRID), and has been running in FY 2010-2014.  Phase III will start in April 2015, and will be organized by the newly established Japanese governmental organization "Japan Agency for Medical Research and Development (AMED)", the so-called Japanese style NIH.  The Collaborative Research Center of Okayama University for Infectious Diseases in India (CRCOUI) was started up in 2007 at the National

    Hydropower plant (HPP) generation comprises a considerable portion of bulk electricity generation and is delivered with a low-carbon footprint. In fact, HPP electricity generation provides the largest share from renewable energy resources, which include wind and solar. Increasing penetration levels of wind and solar lead to a lower inertia on the electric grid, which poses stability challenges. In recent years, breakthroughs in energy storage technologies have demonstrated the economic and technical feasibility of extensive deployments of renewable energy resources on electric grids. If integrated with scalable, multi-time-step energy storage so that the total output can be controlled, multiple run-of-the-river (ROR) HPPs can be deployed. Although the size of a single energy storage system is much smaller than that of a typical reservoir, the ratings of storages and multiple ROR HPPs approximately equal the rating of a large, conventional HPP. This paper proposes cohesively managing multiple sets of energy storage systems distributed in different locations. This paper also describes the challenges associated with ROR HPP system architecture and operation.

  3. Off-grid energy services for the poor: Introducing LED lighting in the Millennium Villages Project in Malawi

    Adkins, Edwin; Eapen, Sandy; Kaluwile, Flora; Nair, Gautam; Modi, Vijay

    2010-01-01

    Lanterns that use light-emitting diodes (LEDs) powered by batteries, which are in turn charged by grid electricity or small solar panels, have emerged as a cost-competitive alternative to kerosene and other fuel-based lighting technologies, offering brighter light for longer duration at equal or lower cost over time. This paper presents lessons learned from the introduction of solar LED lanterns in rural Malawi. We discuss a market-based program using new and existing local commercial structures such as vendors and cooperatives to sell lanterns to village households without subsidy. The paper addresses issues of enterprise development, community interactions, and survey data on lighting use and expenditure patterns before and after LED lantern introduction. Households that purchased a lantern reported high levels of satisfaction with the LED lanterns as well as savings in annual kerosene expenditure comparable to the price of the lantern. These households also reported monthly incomes comparable to the price of the LED lanterns whereas non-adopters surveyed reported monthly incomes about half this level, suggesting a need for financing options to maximize adoption among poorer populations in rural areas. These results suggest that similar market based models of LED lighting technology dissemination have the potential to be replicated and scaled up in other off-grid regions in developing countries. However, viability of local cooperatives and supply chains for lantern products over the medium-to-long term remain to be assessed.

  4. Legitimizing Security in the Ivory Tower: Canadian University Corporate Security Services' Public Quest for Legitimacy.

    Wilkinson, Blair

    2016-05-01

    This article examines how university corporate security (UCS) services engage in legitimation work in their attempts to make their university communities (i.e., faculty, staff, students) and political masters (i.e., university administrators, boards of governors, senators) believe that they are honest, trustworthy, and caring and have authority that should be deferred to. This is accomplished through the analysis of interview and observational data collected as part of a research project exploring UCS services at five Canadian universities and an examination of how UCS services at 14 Canadian universities communicate using the social media service Twitter. These UCS services were found to primarily use Twitter for the purposes of soliciting or requesting information and for networking. In communicating through Twitter, UCS services engage in public legitimation work in which they make claims about and attempt to demonstrate their expertise, authority, and accountability. This article argues that both UCS services' particular legitimacy problem (i.e., their possession of both private and public attributes) and the interactive nature of public legitimation work create tensions that may serve to disrupt UCS services' ability to attain legitimacy. Cet article examine la manière dont les services de sécurité d'entreprise à l'université (SEU) s'engagent à légitimer leurs tentatives de persuader leurs communautés universitaires (c'est-à-dire le corps professoral, le personnel et les étudiants) ainsi que la haute administration (c'est-à-dire les administrateurs de l'université, le conseil des gouverneurs et les sénateurs) qu'ils sont honnêtes, attentifs, dignes de confiance, et qu'ils possèdent un niveau d'autorité auquel quiconque devrait se référer. Ceci sera accompli en analysant un corpus d'entrevues et d'observations dans le cadre d'un projet de recherche examinant les services de type SEU dans cinq universités canadiennes, ainsi qu'une étude sur

    2006-01-01

    Full Text Available National and University Library established remote access to information sources in september 2004. The article describes implementation and development of the service. Library wanted to offer information sources to users wherever and whenever they would need them. First main evaluation criteria for software selection were integration with existing authentication system and second no need for intervention user side. The EZproxy software from Useful Utilities was chosen. Key step to implementation was establishing communication between software applications EZproxy and COBISS library automation system. Library needed to obtain licence agreements from publishers. Promotion campaign aimed to notify large number of users. Only users of National & University Library were able to use the service. Other users and libraries of Ljubljana University requested to authenticate by credentials of their library. Remote access service was developed further in order to enable authentication for other libraries. We needed to establish authentication and authorisation system and also upgrade and install the communication command procedure on different servers. The data about service usage are presented.

  9. Universal access to ambulance does not increase overall demand for ambulance services in Queensland, Australia.

    Tippett, Vivienne C; Toloo, Ghasem Sam; Eeles, David; Ting, Joseph Y S; Aitken, Peter J; Fitzgerald, Gerard J

    2013-02-01

    To determine the impact of the introduction of universal access to ambulance services via the implementation of the Community Ambulance Cover (CAC) program in Queensland in 2003-04. The study involved a 10-year (2000-01 to 2009-10) retrospective analysis of routinely collected data reported by the Queensland Ambulance Service (QAS) and by the Council of Ambulance Authorities. The data were analysed for the impact of policy changes that resulted in universal access to ambulance services in Queensland. QAS is a statewide, publically funded ambulance service. In Queensland, ambulance utilisation rate (AUR) per 1000 persons grew by 41% over the decade or 3.9% per annum (10-year mean=149.8, 95% CI: 137.3-162.3). The AUR mean after CAC was significantly higher for urgent incidents than for non-urgent ones. However projection modelling demonstrates that URs after the introduction of CAC were significantly lower than the projected utilisation for the same period. The introduction of universal access under the Community Ambulance Cover program in Queensland has not had any significant independent long-term impact on demand overall. There has been a reduction in the long-term growth rate, which may have been contributed to by an 'appropriate use' public awareness program.

  11. Distance education: Physics through the University of South Carolina for pre-service and in-service K-12 teachers

    Safko, John L.; Edge, Ronald D.

    1997-03-01

    For the past several years (10 years for JLS, 3 years for RDE) we have been offering telecommunications-based distance education for K-12 teachers through our Office of Distance Education. In addition to practicing teachers and those majoring in science education, we also enroll students who are working on their Master's of Art in Teaching. These latter students often have an undergraduate degree in some science and are completing content and methods courses for state certification as a teacher. These courses are delivered by video cassette and written material. The courses offered are a two semester introductory physics course (by JLS) and a one semester course in physics demonstrations and experiments suitable for the elementary/middle/high school with little or no sources of equipment (by RDE). These courses will be described in the next two sections. First, a few comments on the services provided by the Office of Distance Education and Instructional Services. The University of South Carolina has been offering courses by telecommunications instruction since 1972. During that time it has developed excellent support services for the instructor. Currently the university offers courses live over satellite links and by video cassette to over 10,000 students. The office provides recording capabilities as well as taking care of distribution of video and print materials. They coordinate the receipt and return of any assignments and exams and provide student services for questions about enrollment, supplies, and other technical problems versus content questions. Keeping all of this organized is a full time job for many staff.

    Little is known regarding public opinion of prehospital care in Malaysia. This study was conducted to find out the public's perception and expectations of the ambulance services in one of the university hospitals in Malaysia. A six-month prospective cross-sectional study to look at patients' perception of Hospital Universiti Sains Malaysia's (HUSM) ambulance service was conducted from February 2006 to July 2006. Upon arrival at the hospital, patients or their relatives (who used our hospital's ambulances) were interviewed with a set of questions regarding their perception of the ambulance services and were asked to rate the perception on a Likert Scale from 1 to 10. A convenient sampling method was applied. A total of 87 samples were obtained. Despite the many problems faced by the ambulance service in HUSM, the mean score for each of the questions on patient's perception ranged from 9.33 to 9.70 out of 10. The questions with the highest mean score, which were both 9.70 each, were related to staff attentiveness and staff gentleness. Patients' perceptions can be very subjective, but until further similar studies could be carried out in other parts of Malaysia, this set of data merely represents a numerical measure of public perception of the ambulance services from HUSM.

  13. Knowledge services in science and technology - improving the university/research centre - company relationship

    Magalhaes, Adriana Braz Vendramini Bicca

    2009-01-01

    This research proposes a conceptual model for Knowledge Services Structure applicable to Science and Technology Parks (STP) and targeted to micro, small and medium enterprises, in order to improve the business - university - research centers relationship. The idea emerged from exploratory studies on STP and the observation of a knowledge gap on this subject: academic studies that have proposed support services structures to link companies - university - research centers in STP were not available. The study methodology is composed by: exploratory studies complemented by action research. Five aspects of analysis (knowledge services, business development, ordinary/ S and T infrastructure services, expansion of area, and image / visibility) were chosen; a questionnaire based on the these aspects were elaborated and applied by e-mail (e-survey), using as data-base the IASP associated members for the selection of potential respondents. The questionnaire was answered by STP managers from different countries (Spain, Italy, Portugal, Germany, United Kingdom, China, Brazil, Turkey and Uruguay) and, for a deeper and better answers understanding, presential interviews were conducted in certain European STP. After presentation, analysis and discussion of the results, a conceptual model of knowledge service structure for STP has been made, using as basis the Technology Park of Sao Paulo structure. During the formulation of the conceptual model stage, a brief discussion on the importance of knowing and meet the customer needs meant on the inclusion of a customer-interface in the final model.

  18. Grid Security

    CERN. Geneva

    2004-01-01

    The aim of Grid computing is to enable the easy and open sharing of resources between large and highly distributed communities of scientists and institutes across many independent administrative domains. Convincing site security officers and computer centre managers to allow this to happen in view of today's ever-increasing Internet security problems is a major challenge. Convincing users and application developers to take security seriously is equally difficult. This paper will describe the main Grid security issues, both in terms of technology and policy, that have been tackled over recent years in LCG and related Grid projects. Achievements to date will be described and opportunities for future improvements will be addressed.

  1. Integrating medical, assistive, and universal design products and technologies: Assistive Technology Service Method (ATSM).

    Elsaesser, Linda-Jeanne; Bauer, Stephen

    2012-07-01

    ISO26000 provides guidance on effective organizational performance that recognizes social responsibility (including rights of persons with disabilities (PWD)), engages stakeholders, and contributes to sustainable development [1]. Millennium Development Goals 2010 state: while progress has been made, insufficient dedication to sustainable development, and inequalities to the most vulnerable people require attention [2]. World Report on Disability 2011 recommendations includes improved data collection and removal of barriers to rehabilitation that empower PWD [3]. The Assistive Technology Service Method (ATSM), Assistive Technology Device Classification (ATDC) and Matching Person and Technology (MPT) provide an evidence-based, standardized, internationally comparable framework to improve rehabilitation interventions [4-6]. The ATSM and ATDC support universal design (UD) principles and provision of universal technology. The MPT assures interventions are effective and satisfactory to end-users [7]. The ICF conceptual framework and common language are used throughout [8]. Research findings on healthcare needs are translated. ATSM applications in support of these findings are presented. National initiatives demonstrate the need and value of the ATSM as an evidence-based, user-centric, interdisciplinary method to improve individual and organizational performance for rehabilitation [including AT] services. Two Disability & Rehabilitation: Assistive Technology articles demonstrate ATSM and ATDC use to strengthen rehabilitation services and integrate Universal Design principles for socially responsible behavior.

    2011-12-22

    The initial federal funding for the Colorado State University Smart Grid Integration Laboratory is through a Congressionally Directed Project (CDP), DE-OE0000070 Smart Grid Integration Laboratory. The original program requested in three one-year increments for staff acquisition, curriculum development, and instrumentation all which will benefit the Laboratory. This report focuses on the initial phase of staff acquisition which was directed and administered by DOE NETL/ West Virginia under Project Officer Tom George. Using this CDP funding, we have developed the leadership and intellectual capacity for the SGIC. This was accomplished by investing (hiring) a core team of Smart Grid Systems engineering faculty focused on education, research, and innovation of a secure and smart grid infrastructure. The Smart Grid Integration Laboratory will be housed with the separately funded Integrid Laboratory as part of CSU's overall Smart Grid Integration Center (SGIC). The period of performance of this grant was 10/1/2009 to 9/30/2011 which included one no cost extension due to time delays in faculty hiring. The Smart Grid Integration Laboratory's focus is to build foundations to help graduate and undergraduates acquire systems engineering knowledge; conduct innovative research; and team externally with grid smart organizations. Using the results of the separately funded Smart Grid Workforce Education Workshop (May 2009) sponsored by the City of Fort Collins, Northern Colorado Clean Energy Cluster, Colorado State University Continuing Education, Spirae, and Siemens has been used to guide the hiring of faculty, program curriculum and education plan. This project develops faculty leaders with the intellectual capacity to inspire its students to become leaders that substantially contribute to the development and maintenance of Smart Grid infrastructure through topics such as: (1) Distributed energy systems modeling and control; (2) Energy and power conversion; (3

    Full Text Available This article describes important elements of the operationalization of sign language translation and interpretation services in southern Brazil federal universities. Using as reference some authors of the disciplinary field of Translation Studies, such as Ozolins (2010, Baker and Saldanha (2009, Baker (2006, and Tymoczko (2007, this article discusses issues that involve community interpreting, its challenges and perspectives of implementation in the scope of public service in Brazil. The methodological orientation follows the qualitative approach with focus on descriptive research. Therefore, a survey was carried out to analyze the situation of Brazilian Sign Language-Portuguese translators and interpreters who are regular civil servants and work at the federal universities of Brazilian southern states. The guiding questions for that matter are the following ones: who are the translators and interpreters of Brazilian sign language in southern Brazil? Which is the level of education of those professionals? The results registered 76 regular servants in the universities investigated, most of which have an undergraduate degree or specialization. Fewer of them have master's and doctoral degrees. Other results include their distribution by state and by university, and the areas of knowledge in which they have developed research so far.

    Michele P. Claibourn

    2015-07-01

    Full Text Available Every story has a beginning, where the narrator chooses to start, though this is rarely the genesis. This story begins with the launch of the University of Virginia Library's new Research Data Services unit in October 2013. Born from the conjoining of a data management team and a data analysis team, Research Data Services expanded to encompass data discovery and acquisitions, research software support, and new expertise in the use of restricted data. Our purpose is to respond to the challenges created by the growing ubiquity and scale of data by helping researchers acquire, analyze, manage, and archive these resources. We have made serious strides toward becoming ‘the face of data services at U.Va.’  This article tells a bit of our story so far, relays some early challenges and how we've responded to them, outlines several initial successes, and summarizes a few lessons going forward.

  14. Workshop on Future Generation Grids

    Laforenza, Domenico; Reinefeld, Alexander

    2006-01-01

    The Internet and the Web continue to have a major impact on society. By allowing us to discover and access information on a global scale, they have created entirely new businesses and brought new meaning to the term surf. In addition, however, we want processing, and increasingly, we want collaborative processing within distributed teams. This need has led to the creation of the Grid - an infrastructure that enables us to share capabilities, and integrate services and resources within and across enterprises. "Future Generation Grids" is the second in the "CoreGRID" series. This edited volume brings together contributed articles by scientists and researchers in the Grid community in an attempt to draw a clearer picture of the future generation Grids. This book also identifies some of the most challenging problems on the way to achieving the invisible Grid ideas

  15. A profile of students receiving counselling services at a university in post-apartheid South Africa.

    Bowman, Brett; Payne, Jarrod

    2011-12-01

    The purpose of this study was to describe a profile of students seeking counselling at a racially diverse university in post-apartheid South Africa as a means to demonstrate the importance of routinely collecting and analysing student counselling data at university-based centres across the country. Student data were extracted from the only two counselling centres based at the University of the Witwatersrand in Johannesburg that provided services to 831 students during 2008. The 26 243 students that did not seek counselling during this period formed the comparison group. These data were analysed using logistic regression. Black, female and students within the 21-25 year age category were more likely to receive counselling, and presenting problems varied by population group. Given the country's past and continued levels of social asymmetry, we argue that the development of standardised university-based reporting systems able to describe the characteristics and presenting problems of students seeking counselling across South African universities should be prioritised by its higher education sector. Timely access to information of this kind is crucial to the generation of evidence-based mental health interventions in a population that is especially important to the country's development vision.

  17. Smart grids - French Expertise

    2015-11-01

    The adaptation of electrical systems is the focus of major work worldwide. Bringing electricity to new territories, modernizing existing electricity grids, implementing energy efficiency policies and deploying renewable energies, developing new uses for electricity, introducing electric vehicles - these are the challenges facing a multitude of regions and countries. Smart Grids are the result of the convergence of electrical systems technologies with information and communications technologies. They play a key role in addressing the above challenges. Smart Grid development is a major priority for both public and private-sector actors in France. The experience of French companies has grown with the current French electricity system, a system that already shows extensive levels of 'intelligence', efficiency and competitiveness. French expertise also leverages substantial competence in terms of 'systems engineering', and can provide a tailored response to meet all sorts of needs. French products and services span all the technical and commercial building blocks that make up the Smart Grid value chain. They address the following issues: Improving the use and valuation of renewable energies and decentralized means of production, by optimizing the balance between generation and consumption. Strengthening the intelligence of the transmission and distribution grids: developing 'Supergrid', digitizing substations in transmission networks, and automating the distribution grids are the focus of a great many projects designed to reinforce the 'self-healing' capacity of the grid. Improving the valuation of decentralized flexibilities: this involves, among others, deploying smart meters, reinforcing active energy efficiency measures, and boosting consumers' contribution to grid balancing, via practices such as demand response which implies the aggregation of flexibility among residential, business, and/or industrial sites. Addressing current technological challenges, in

    2016-01-01

    Full Text Available Objectives: to explore nurses' knowledge of universal health coverage (UHC for inclusive and sustainable development of elderly care services. Method: this was a cross-sectional survey. A convenience sample of 326 currently practicing enrolled nurses (EN or registered nurses (RN was recruited. Respondents completed a questionnaire which was based on the implementation strategies advocated by the WHO Global Forum for Governmental Chief Nursing Officers and Midwives (GCNOMs. Questions covered the government initiative, healthcare financing policy, human resources policy, and the respondents' perception of importance and contribution of nurses in achieving UHC in elderly care services. Results: the knowledge of nurses about UHC in elderly care services was fairly satisfactory. Nurses in both clinical practice and management perceived themselves as having more contribution and importance than those in education. They were relatively indifferent to healthcare policy and politics. Conclusion: the survey uncovered a considerable knowledge gap in nurses' knowledge of UHC in elderly care services, and shed light on the need for nurses to be more attuned to healthcare policy. The educational curriculum for nurses should be strengthened to include studies in public policy and advocacy. Nurses can make a difference through their participation in the development and implementation of UHC in healthcare services.

  19. Satisfaction With Medication Therapy Management Services at a University Ambulatory Care Clinic.

    Kim, Shiyun; Martin, Michelle T; Pierce, Andrea L; Zueger, Patrick

    2016-06-01

    A survey was issued to patients enrolled in the Medication Therapy Management Clinic (MTMC) at University of Illinois Hospital and Health Sciences (June 2011-January 2012) in order to assess satisfaction with pharmacy services provided by pharmacists. A 23-item survey was offered to 65 patients in the MTMC program before or after clinic visits. Since there is a paucity of data indicating the level of satisfaction with MTM services provided by pharmacists, this survey may contribute to the process of building a greater collaboration between the pharmacist and patient. Sixty-two of 65 patients completed the survey; satisfaction with MTMC pharmacists was demonstrated to be significantly positively correlated with overall satisfaction with the MTMC. Patient satisfaction is not significantly different according to age, gender, ethnicity, or number of disease states. Satisfaction with the pillbox service is not significantly different between younger and older patients. It was also noted that patients taking a greater number of medications had higher levels of satisfaction. Most patients indicated that they were satisfied with the MTMC pharmacists and services; further study linking patient satisfaction with MTM services to improved patient outcomes may allow our MTMC to serve as a model for other pharmacist-managed MTMCs serving similar patient populations. © The Author(s) 2014.

  20. Factors Influencing the Utilization of Voluntary Counselling and Testing Services among University Students in Kenya

    Mwangi, Rose; Ngure, Peter; Thiga, Moses; Ngure, Jane

    2014-01-01

    Voluntary Counselling and Testing (VCT) is recognized as a critical component of effective HIV prevention initiative and has therefore been promoted nationally and within universities in Kenya. Upon successful counselling and testing those found to be HIV negative are informed to take the necessary measures to protect themselves while the infected are advised to start the required medication. This study examined the attitudes toward VCT services among university students in four Kenyan universities. 980 students filled self administered questionnaires. Results showed that 38.5% of the subjects had tested for HIV in the last 12 months and students (55.8%) felt less susceptible to HIV infection. Findings from a factor analysis revealed that the intention to seek the services was associated with five attitude subscales that were ranked as follows (i) people’s and personal concerns, (ii) friends concerns, (iii) value of testing, (iv) confidentiality and support, and (v) perceived susceptibility. The first three items are associated with stigma which was evidenced in the subjects’ report that admitting that one should test for HIV would imply that one has engaged in immoral behaviour. Secondly, subjects felt that their friends would look down on them if they tested for HIV. Knowing the students’ attitudes will therefore assist in the development of appropriate VCT interventions that will promote HIV testing and behaviour change. PMID:24999153

  1. The post-2015 delivery of universal and sustainable access to infrastructure services. Working Paper

    Doczi, Julian, Dorr, Tobias; Mason, Nathaniel; Scott, Andrew

    2013-06-15

    In this new working paper, the authors focus specifically on what would be necessary to achieve High Level Panel-style goals and targets for water, energy and transport, if these were to be eventually adopted by world leaders. In all three cases, much of the advocacy - and the proposed High Level Panel goals - have emphasized the need to strive for universal and sustainable access to at least basic levels of services from these sectors. Many of the proposals for post-2015 goals and targets appear ambitious, but what would it take to achieve them? This paper assesses what is needed to achieve goals for universal and sustainable access to infrastructure, specifically water, energy and transport. Using illustrative goals and targets, the paper reviews the development challenges in each sector, and what will be necessary to overcome the barriers to universal and sustainable access to water, energy and transport infrastructure services, in the areas of governance, finance, capacity development and environmental protection. The paper ends with general conclusions about infrastructure in the post-2015 development agenda.

  2. Impelementation of Information Technology Service Management at Data And Information System Center of XYZ University

    Kornelius Irfandhi

    2016-03-01

    Full Text Available Information Technology (IT is increasingly progressing. Nowadays, the success of a business of the organization/company is highly dependent on the IT infrastructure used. Therefore, organizations/companies have to manage their IT service to be optimal to their customers. Looking at this matter and the increasing dynamics of XYZ University, then Data and Information System Center (Pusdatin - an IT provider of XYZ University began implementing IT Service Management (ITSM from 2013 using the latest version of Information Technology Infrastructure Library (ITIL, namely ITIL v3 as a framework for implementing ITSM in its business processes. However, along the way, there are still some problems happen in Pusdatin in order that ITSM can actually support and align with the objectives of XYZ University. Through this paper, the authors want to explain how the implementation of ITSM at Pusdatin, identify the problems related to the implementation of ITSM, and provide the solutions for each problem. The methods used are direct observation to Pusdatin, conductan interview with the Head of Pusdatin and Staff of Pusdatin, and also perform a literature review of books and papers that discuss about ITIL. The result of this research is that ITSM process of Pusdatin generally works quite well but there are still some shortcomings because ITSM is not 100% implemented in all areas.

  3. Sink-oriented Dynamic Location Service Protocol for Mobile Sinks with an Energy Efficient Grid-Based Approach

    Hyunseung Choo

    2009-03-01

    Full Text Available Sensor nodes transmit the sensed information to the sink through wireless sensor networks (WSNs. They have limited power, computational capacities and memory. Portable wireless devices are increasing in popularity. Mechanisms that allow information to be efficiently obtained through mobile WSNs are of significant interest. However, a mobile sink introduces many challenges to data dissemination in large WSNs. For example, it is important to efficiently identify the locations of mobile sinks and disseminate information from multi-source nodes to the multi-mobile sinks. In particular, a stationary dissemination path may no longer be effective in mobile sink applications, due to sink mobility. In this paper, we propose a Sink-oriented Dynamic Location Service (SDLS approach to handle sink mobility. In SDLS, we propose an Eight-Direction Anchor (EDA system that acts as a location service server. EDA prevents intensive energy consumption at the border sensor nodes and thus provides energy balancing to all the sensor nodes. Then we propose a Location-based Shortest Relay (LSR that efficiently forwards (or relays data from a source node to a sink with minimal delay path. Our results demonstrate that SDLS not only provides an efficient and scalable location service, but also reduces the average data communication overhead in scenarios with multiple and moving sinks and sources.

  5. Assessment of client satisfaction on emergency department services in Hawassa University Referral Hospital, Hawassa, Southern Ethiopia.

    Worku, Mesfin; Loha, Eskindir

    2017-06-27

    Satisfaction refers to a state of pleasure or contentment with an action, event or service, especially one that was previously desired. Regarding to client, satisfaction is the level of happiness that clients experience having used a service. It therefore reflects the gap between the expected service and the experience of the service, from the client's point of view. Information was unavailable regarding the level of satisfaction of patients towards emergency health care servicesat Hawassa University Referral Hospital thatserve a huge catchment area; and this study addressed this gap. Cross-sectional study was conducted from March 13 to May 15/2014. Systematic sampling method was used to enroll study participants. The data was collected by trained data collectors using pre-structured questionnaire. A total 407 clients were enrolled under this study with respondent rate of 96.9%. Nearly two third of study participants were male, 270 (66.3%). 86.7% of study participants were satisfied by services provided in Emergency Out Patient Department (OPD). The percentage of study satisfaction with physical examination by Doctor, nursing, laboratory and pharmacy services were 95.6%, 89.9%, 84.7% and 67.6%, respectively. Only 31.9% were satisfied with availability of drugs in the pharmacy. Regarding to staff courtesy, 91.7% of study participants were satisfied by the manner shown by the staffs working in Emergency OPD. The vast majority of the participants (97%) were satisfied with the courtesy of Medical laboratory personnel and the least satisfaction (79.4%) was recorded for security guards. This study showed low level of patient satisfaction in pharmacy services specifically due to unavailability of drugs due to lack of sustained supply of drugs.

  6. Post-graduation survey of the impact of geoscience service-learning courses at Wesleyan University

    OConnell, S.; Ptacek, S.; Diver, K.; Ku, T. C.; Resor, P. G.; Royer, D. L.

    2016-12-01

    The benefits of service-learning courses are extolled in numerous papers and include increases in student: engagement with the material and the world, self-efficacy, and awareness of personal values. This approach to education allows students to develop skills that may not be part of many lecture-style or even laboratory class formats, such as problem solving, scientific communication, group work and reflection. Service learning requires students to move to the upper level of Bloom's taxonomy of cognitive skills: analyzing, evaluating, and creating. In a broader context, service learning offers two distinct benefits for the geosciences. First, service learning offers an opportunity for both the students and community to see the utility of geoscience in their lives and what geoscientists do. Considering the general lack of knowledge about geosciences this is an important public relations opportunity. Second, some studies have shown that the benefits of a service-learning approach to education results in higher performance by underrepresented minority students, students that the geosciences need to attract in an increasingly diverse society. Since 2006, four different service-learning courses have been offered by the Department of Earth & Environmental Sciences at Wesleyan University to both majors and non-majors. They are Environmental Geochemistry (core course), Geographic Information Systems (elective), Science on the Radio (first-year seminar), and Soils (elective). Almost 250 graduates have taken these courses. Graduates were surveyed to discover what they gained by taking a service-learning course and if, and how, they use the skills they learned in the course in their post-college careers.

    To find out the satisfaction of clinical units with laboratory services in a university hospital, to point out the most important problems and defects in services, to carry out corrective actions, and thereafter to identify the possible changes in satisfaction. and Senior physicians and nurses-in-charge of the clinical units at Oulu University Hospital, Finland. Customer satisfaction survey using a questionnaire was carried out in 2001, indicating the essential aspects of laboratory services. Customer-specific problems were clarified, corrective actions were performed, and the survey was repeated in 2004. In 2001, the highest dissatisfaction rates were recorded for computerized test requesting and reporting, turnaround times of tests, and the schedule of phlebotomy rounds. The old laboratory information system was not amenable to major improvements, and it was renewed in 2004-05. Several clinical units perceived turnaround times to be long, because the tests were ordered as routine despite emergency needs. Instructions about stat requesting were given to these units. However, no changes were evident in the satisfaction level in the 2004 survey. Following negotiations with the clinics, phlebotomy rounds were re-scheduled. This resulted in a distinct increase in satisfaction in 2004. Satisfaction survey is a screening tool that identifies topics of dissatisfaction. Without further clarifications, it is not possible to find out the specific problems of customers and to undertake targeted corrective actions. Customer-specific corrections are rarely seen as improvements in overall satisfaction rates.

    2008-06-18

    Higher education is growing fast and every day it becomes more and more exposed to globalization processes. The aim of this study was to determine the quality gap of educational services by using a modified SERVQUAL instrument among students in Hormozgan University of Medical Sciences. A cross-sectional study was carried out at Hormozgan University of Medical Sciences in 2007. In this study, a total of 300 students were selected randomly and asked to complete a questionnaire that was designed according to SERVQUAL methods. This questionnaire measured students' perceptions and expectations in five dimensions of service that consists of assurance, responsiveness, empathy, reliability and tangibles. The quality gap of educational services was determined based on differences between students' perceptions and expectations. The results demonstrated that in each of the five SERVQUAL dimensions, there was a negative quality gap. The least and the most negative quality gap means were in the reliability (-0.71) and responsiveness (-1.14) dimensions respectively. Also, there were significant differences between perceptions and expectations of students in all of the five SERVQUAL dimensions (p < 0.001). Negative quality gaps mean students' expectations exceed their perceptions. Thus, improvements are needed across all five dimensions.

  9. Enabling Mobile Communications for the Needy: Affordability Methodology, and Approaches to Requalify Universal Service Measures

    Louis-Francois PAU

    2009-01-01

    Full Text Available This paper links communications and media usage to social and household economics boundaries. It highlights that in present day society, communications and media are a necessity, but not always affordable, and that they furthermore open up for addictive behaviors which raise additional financial and social risks. A simple and efficient methodology compatible with state-of-the-art social and communications business statistics is developed, which produces the residual communications and media affordability budget and ultimately the value-at-risk in terms of usage and tariffs. Sensitivity analysis provides precious information on bottom-up communications and media adoption on the basis of affordability. This approach differs from the regulated but often ineffective Universal service obligation, which instead of catering for individual needs mostly addresses macro-measures helping geographical access coverage (e.g. in rural areas. It is proposed to requalify the Universal service obligations on operators into concrete measures, allowing, with unchanged funding, the needy to adopt mobile services based on their affordability constraints by bridging the gap to a standard tariff. Case data are surveyed from various countries. ICT policy recommendations are made to support widespread and socially responsible communications access.

    Full Text Available : In spite of increasing interests and trends among Iranian organizations to incorporate information and communication technology (ICT into service provision to their customers, there is still considerable gap between existing and expected diffusion. The aim of this study was to identify and evaluate main determinants of technology adoption and use on the basis of modified TAM model. The developed model was validated through survey research and data collected from a randomly selected sample of 263 students at Ferdowsi University of Mashhad. Data analysis was conducted using appropriate statistical techniques including regression, and Chaves analysis. The findings of research confirmed the validity of principle model , confirming ease of use and perceived usefulness as main determinants of technology acceptance as suggested by Davis. This study also suggested that the quality of system and personal ability to use technology were good predictors of ease of use, while social interaction and images appeared to be good predictors of perceived usefulness of technology. Furthermore, personal innovativeness proved to have significant effect on intention to use among potential ICT users.

    2001-01-01

    Full Text Available In its 30 years of operation, Athabasca University has witnessed the full impact of the growth of online distance education. Its conversion from mixed media course production and telephone/ mail tutoring to a variety of electronic information and communication technologies has been heterogeneous across disciplines and programs. Undergraduate programs in business, computing, and some social science programs have largely led the conversion, and all graduate programs have, since their inception, employed various features of online delivery. The parallel conversion of student services has been equally important to the effectiveness of these processes. The implications of this approach for the quality of offerings, support systems, costing, and the primary mandate of the University (which is to remove barriers, not create them are discussed.

    2017-01-01

    Full Text Available Introduction: Sustainable development of higher educational systems, as a dynamic system, requires a coherent moderate growth both in qualitative and quantitative dimensions. Since students are the major clients of higher education systems and their perspectives can play a key role in the quality promotion of the services; this study has been conducted based on SERVQUAL model aiming at the assessment of educational services quality in Kashan Medical Science University in 2016. Study Methodology: A total of 212 students of Kashan Medical Science University were selected with a population of 616 subjects through random sampling, using Morgan tables for this descriptive-analytical research. Data collection tools were the standard SERVQUAL questionnaire composing of three sections of basic information and 28 items, according to Likert six-option scale for the measurement of services quality current and desired expected conditions. The difference between the average of current and desirable statuses was measured as the services gap. Descriptive deductive statistics were used to analyze the obtained data. Results: The students aged averagely 23 ± 1.8, 65% (138 subjects were female, and 35% (74 subjects were male. About 72% (153 subjects were single, and 28% (59 subjects were married. The obtained results revealed that there was a negative gap in all dimensions of quality. The results also showed that the minimum gap obtained for learning assist tools (physical and tangibility dimensions with an amount of −0.38 and the maximum gap for guide instructor availability once needed by the students (accountability dimension with an amount of −2.42. Total mean of perceptions and expectations measurement for the students obtained 2.28 and 3.85, respectively. Conclusion: Respecting the negative gap obtained for all dimensions of educational services quality and insufficiencies to meet the students' expectations, it is recommended to assign further resources

    The process of deregulation in network industries, in particular in the electric sector, raises the problem of financing the Universal Service Obligations (USO) corresponding to the production, transport and distribution operations. In this paper, we study three ways of funding for an USO of production, especially the 'green' electricity development; the financing with cross-subsidies, the implementation of a fund (financing by a tax) and finally a voluntary funding system by direct subscriptions of consumers. We notably show that this last one Pareto dominates mostly, from a welfare point of view, the other scenarios. (authors)

  17. Integrated Specialized Early-Course Psychosis Treatment Services - University Psychiatric Hospital Vrapce Model.

    Ostojić, DraŽenka; Čulo, Ilaria; Silić, Ante; Kos, Suzana; Savić, Aleksandar

    2018-06-01

    First episode of psychosis presents a critical period in terms of numerous associated risks, but also possibilities for effective therapeutic interventions. There is a continued focus on early interventions in prodromal states and early course of frank psychosis, aimed at ensuring faster remission, reducing relapses, achieving better long-term functioning, and preventing adverse outcomes linked to untreated psychosis and chronic psychotic disorders. A number of different specialized treatment models and services exist trying to close knowledge gaps and provide clinical interventions to first-episode psychosis (FEP) patients, but there is still no generally accepted standard of care informing our every-day practice. FEP and early-course psychosis specialized treatment model developed in 2004 in University Psychiatric Hospital Vrapce rests on integration of care across different organization units and clinical presentation acuity levels and patient needs (intensive care, FEP inpatient unit, FEP outpatient services including day hospital). Such integration of FEP services allows for flexible entry point on multiple levels, earlier structuring of therapeutic alliance for those requiring inpatient care, reduction of risks associated with FEP, quicker formation of long-term treatment plans, reduction of delay in accessing specialized services, and a more coordinated diagnostic process and recruitment of FEP patient population. Detailed evaluations of outcomes and comparisons with different treatment models are necessary in order to assess strengths and weaknesses of each specific model and inform modifications to current practice models.

    2015-12-01

    Delaware State University is working toward infusing undergraduate education with climate change science and enhancing the climate change learning content of pre-service teacher preparation programs as part of the MADE-CLEAR project (www.madeclear.org). Faculty development workshops have been conducted to prepare and educate a cadre of faculty from different disciplines in global climate science literacy. Following the workshops, the faculty participants have integrated climate literacy tenets into their existing curriculum. Follow up meetings have helped the faculty members to use specific content in their curriculum such as greenhouse gases, atmospheric CO2, sea level rise, etc. Additional training provided to the faculty participants in pedagogical methods of climate change instruction to identify common misconceptions and barriers to student understanding. Some pre-service teachers were engaged in summer internships and learned how to become messenger of climate change science by the state parks staff during the summer. Workshops were offered to other pre-service teachers to teach them specific climate change topics with enhanced hands-on laboratory activities. The participants were provided examples of lesson plans and guided to develop their own lesson plans and present them. Various pedagogical methods have been explored for teaching climate change content to the participants. The pre-service teachers found the climate content very challenging and confusing. Training activities were modified to focus on targeted topics and modeling of pedagogical techniques for the faculty and pre-service teachers. Program evaluation confirms that the workshop participant show improved understanding of the workshop materials by the participants if they were introduced few climate topics. Learning how to use hands-on learning tools and preparing lesson plans are two of the challenges successfully implemented by the pre-service teachers. Our next activity includes pre-service

    2017-11-02

    University students are at risk for acquiring sexually transmitted infections and suffering other negative health outcomes. Sexual health services offer preventive and treatment interventions that aim to reduce these infections and associated health consequences. However, university students often delay or avoid seeking sexual health services. An in-depth understanding of the factors that influence student use of sexual health services is needed to underpin effective sexual health interventions. In this study, we aim to design a behavior change intervention to address university undergraduate students' use of sexual health services at two universities in Nova Scotia, Canada. This mixed methods study consists of three phases that follow a systematic approach to intervention design outlined in the Behaviour Change Wheel. In Phase 1, we examine patterns of sexual health service use among university students in Nova Scotia, Canada, using an existing dataset. In Phase 2, we identify the perceived barriers and enablers to students' use of sexual health services. This will include focus groups with university undergraduate students, health care providers, and university administrators using a semistructured guide, informed by the Capability, Opportunity, Motivation-Behaviour Model and Theoretical Domains Framework. In Phase 3, we identify behavior change techniques and intervention components to develop a theory-based intervention to improve students' use of sexual health services. This study will be completed in March 2018. Results from each phase and the finalized intervention design will be reported in 2018. Previous intervention research to improve university students' use of sexual health services lacks a theoretical assessment of barriers. This study will employ a mixed methods research design to examine university students' use of sexual health service and apply behavior change theory to design a theory- and evidence-based sexual health service intervention.

  1. Providing Limited Local Electric Service During a Major Grid Outage: A First Assessment Based on Customer Willingness to Pay.

    Baik, Sunhee; Morgan, M Granger; Davis, Alexander L

    2018-02-01

    While they are rare, widespread blackouts of the bulk power system can result in large costs to individuals and society. If local distribution circuits remain intact, it is possible to use new technologies including smart meters, intelligent switches that can change the topology of distribution circuits, and distributed generation owned by customers and the power company, to provide limited local electric power service. Many utilities are already making investments that would make this possible. We use customers' measured willingness to pay to explore when the incremental investments needed to implement these capabilities would be justified. Under many circumstances, upgrades in advanced distribution systems could be justified for a customer charge of less than a dollar a month (plus the cost of electricity used during outages), and would be less expensive and safer than the proliferation of small portable backup generators. We also discuss issues of social equity, extreme events, and various sources of underlying uncertainty. © 2017 Society for Risk Analysis.

    Cushing, Katherine F; Carson, Anna E; Short, Tyiesha D; Kot, Stefanie N; Tschokert, Merete; Sales, Jessica M

    2018-04-13

    Although two-thirds of graduating high school seniors attend college or university in the U.S., there is a paucity of national or state specific research regarding SRH services available on or near college and university campuses. A review of websites for all colleges and universities in Georgia was conducted to evaluate sexual health services available on campuses and evidence of referral to community providers. Of 96 colleges in Georgia, 44░had campus-located health centers, with only 3 at two-year colleges. Overall SRH service provision was low, with great variation between colleges. Distances between colleges and Title X clinics ranged from 0.33 to 35.45 miles. Many students lack access to campus health centers, and information on college websites regarding SRH service availability and referrals differs dramatically between campuses. In the absence of robust campus-located services, schools should highlight where students can obtain comprehensive SRH care in the community.

  3. Power grids

    Viterbo, J.

    2012-01-01

    The implementation of renewable energies represents new challenges for electrical systems. The objective: making power grids smarter so they can handle intermittent production. The advent of smart grids will allow flexible operations like distributing energy in a multidirectional manner instead of just one way and it will make electrical systems capable of integrating actions by different users, consumers and producers in order to maintain efficient, sustainable, economical and secure power supplies. Practically speaking, they associate sensors, instrumentation and controls with information processing and communication systems in order to create massively automated networks. Smart grids require huge investments: for example more than 7 billion dollars have been invested in China and in the Usa in 2010 and France is ranked 9. worldwide with 265 million dollars invested. It is expected that smart grids will promote the development of new business models and a change in the value chain for energy. Decentralized production combined with the probable introduction of more or less flexible rates for sales or purchases and of new supplier-customer relationships will open the way to the creation of new businesses.

    proposed to establish a service packages, whether through a single obligatory list or through the definition of a flexible, high priority set to be offered to specific populations according to their economic possibilities. For the strategic purchasing of services, two alternatives are proposed: to assign the fund either to a single national manager or to each of the existing public provider institutions, with the expectation that they would contract across each other and with private providers to fulfill their complementary needs.The proposal does not consider the risks and alternatives to a single tax contribution fund, which could have been suggested given that it is not an essential part of a National Universal Health System. However, it is necessary to discuss in more detail the roles and strategies for a national single-payer, especially for the strategic purchasing of high-cost and specialized interventions in the context of public and private providers. The alternative of allocating funds directly to providers would undermine the incentives for competition and collaboration and the capacity to steer providers towards the provision of high quality health services.It is proposed to focus the discussion of the reform of the national health system around strategic purchasing and the functions and structure of a single-payer as well as of agencies to articulate integrated health service networks as tools to promote quality and efficiency of the National Universal Health System. The inclusion of economic incentives to providers will be vital for competition, but also for the cooperation of providers within integrated, multi-institutional health service networks.Health professionals and sector policy specialists coordinated by the Centro de Estudios Espinosa Yglesi as in Mexico propose a policy to anchor the health system in primary care centered on the individual. The vision includes effective stewardship,solid financing, and the provision of services by a

  5. Developing library bioinformatics services in context: the Purdue University Libraries bioinformationist program.

    Rein, Diane C

    2006-07-01

    Purdue University is a major agricultural, engineering, biomedical, and applied life science research institution with an increasing focus on bioinformatics research that spans multiple disciplines and campus academic units. The Purdue University Libraries (PUL) hired a molecular biosciences specialist to discover, engage, and support bioinformatics needs across the campus. After an extended period of information needs assessment and environmental scanning, the specialist developed a week of focused bioinformatics instruction (Bioinformatics Week) to launch system-wide, library-based bioinformatics services. The specialist employed a two-tiered approach to assess user information requirements and expectations. The first phase involved careful observation and collection of information needs in-context throughout the campus, attending laboratory meetings, interviewing department chairs and individual researchers, and engaging in strategic planning efforts. Based on the information gathered during the integration phase, several survey instruments were developed to facilitate more critical user assessment and the recovery of quantifiable data prior to planning. Given information gathered while working with clients and through formal needs assessments, as well as the success of instructional approaches used in Bioinformatics Week, the specialist is developing bioinformatics support services for the Purdue community. The specialist is also engaged in training PUL faculty librarians in bioinformatics to provide a sustaining culture of library-based bioinformatics support and understanding of Purdue's bioinformatics-related decision and policy making.

  6. How to operate a university institute as a radiological emergency service?

    Besancon, A.; Bochud, F.

    2011-01-01

    The Institute of Radiation Physics (IRA) is attached to the Department of Medical Radiology at the Vaud University Hospital Center (CHUV) in Lausanne. The Institute's main tasks are strongly linked to the medical activities of the Department: radiotherapy, radiodiagnostics, interventional radiology and nuclear medicine. The Institute also works in the fields of operational radiation protection, radiation metrology and radioecology. In the case of an accident involving radioactive materials, the emergency services are able to call on the assistance of radiation protection specialists. In order to avoid having to create and maintain a specific structure, both burdensome and rarely needed, Switzerland decided to unite all existing emergency services for such events. Thus, the IRA was invited to participate in this network. The challenge is therefore to integrate a university structure, used to academic collaborations and the scientific approach, to an interventional organization accustomed to strict policies, a military-style command structure and 'drilled' procedures. The IRA's solution entails mobilizing existing resources and the expertise developed through professional experience. The main asset of this solution is that it involves the participation of committed collaborators who remain in a familiar environment, and are able to use proven materials and mastered procedures, even if the atmosphere of an accident situation differs greatly from regular laboratory routines. However, this solution requires both a commitment to education and training in emergency situations, and a commitment in terms of discipline by each collaborator in order to be integrated into a response plan supervised by an operational command center.

  16. Achieving universal health coverage in small island states: could importing health services provide a solution?

    Walls, Helen; Smith, Richard

    2018-01-01

    Background Universal health coverage (UHC) is difficult to achieve in settings short of medicines, health workers and health facilities. These characteristics define the majority of the small island developing states (SIDS), where population size negates the benefits of economies of scale. One option to alleviate this constraint is to import health services, rather than focus on domestic production. This paper provides empirical analysis of the potential impact of this option. Methods Analysis was based on publicly accessible data for 14 SIDS, covering health-related travel and health indicators for the period 2003–2013, together with in-depth review of medical travel schemes for the two highest importing SIDS—the Maldives and Tuvalu. Findings Medical travel from SIDS is accelerating. The SIDS studied generally lacked health infrastructure and technologies, and the majority of them had lower than the recommended number of physicians in a country, which limits their capacity for achieving UHC. Tuvalu and the Maldives were the highest importers of healthcare and notably have public schemes that facilitate medical travel and help lower the out-of-pocket expenditure on medical travel. Although different in approach, design and performance, the medical travel schemes in Tuvalu and the Maldives are both examples of measures used to increase access to health services that cannot feasibly be provided in SIDS. Interpretation Our findings suggest that importing health services (through schemes to facilitate medical travel) is a potential mechanism to help achieve universal healthcare for SIDS but requires due diligence over cost, equity and quality control.

  17. Enhancing Hubble's vision service missions that expanded our view of the universe

    Shayler, David J

    2016-01-01

    After a 20-year struggle to place a large, sophisticated optical telescope in orbit the Hubble Space Telescope was finally launched in 1990, though its primary mirror was soon found to be flawed. A dramatic mission in 1993 installed corrective optics so that the intended science program could finally begin. Those events are related in a companion to this book, The Hubble Space Telescope: From Concept to Success.   Enhancing Hubble’s Vision: Service Missions That Expanded Our View of the Universe tells the story of the four missions between 1997 and 2009 that repaired, serviced and upgraded the instruments on the telescope to maintain its state-of-the-art capabilities. It draws on first hand interviews with those closely involved in the project. The spacewalking skills and experiences gained from maintaining and upgrading Hubble had direct application to the construction of the International Space Station and help with its maintenance. These skills can be applied to future human and robotic satellite servic...

  18. Health centres' view of the services provided by a university hospital laboratory: Use of satisfaction surveys

    Oja, Paula; Kouri, Timo; Pakarinen, Arto

    2010-01-01

    Customer orientation has gained increasing attention in healthcare. A customer satisfaction survey is one way to raise areas and topics for quality improvement. However, it seems that customer satisfaction surveys have not resulted in quality improvement in healthcare. This article reports how the authors' university hospital laboratory has used customer satisfaction surveys targeted at the health centres in their hospital district. Closed-ended statements of the questionnaire were planned to cover the essential aspects of laboratory services. In addition, an open-ended question asked what was considered to be the most important problem in services. The questionnaires were sent to the medical directors of the health centres. The open-ended question proved to be very useful because the responses specified the main problems in service. Based on the responses, selected dissatisfied customers were contacted to specify their responses and possible corrective actions were taken. It is concluded that a satisfaction survey can be used as a screening tool to identify topics of dissatisfaction. In addition, further clarifications with selected customers are needed to specify the causes for their dissatisfaction and to undertake proper corrective actions. PMID:20205616

    Full Text Available How might one teach mathematics to math-anxious students and at the same time reduce their math anxiety? This paper describes what we found when we incorporated a service learning component into a quantitative reasoning course at Seattle University in Fall 2010 (20 students and Spring 2011 (28 students. The course is taken primarily by humanities majors, many of whom would not take a course in math if they didn’t need to satisfy the university’s core requirement. For the service learning component, each student met with and tutored children at local schools for 1-2 hours per week (total about 15 service hours, kept a weekly journal reflecting on the experience, and wrote a five-page final paper on the importance and reasonable expectations of mathematics literacy. The autobiographies, self-description at the beginning of the class, focus group interviews at the end of the term, journal entries, final essays, and student evaluations indicated that the students gained confidence in their mathematical abilities, a greater interest in mathematics, and a broader sense of the importance of math literacy in modern society. One notable finding was that students discovered that the act of manufacturing enthusiasm about math as a tool for tutoring the children made them more enthusiastic about math in their own courses.

    Public health insurance coverage for preventive care in young adults is incomplete in Korea. Few studies have focused on young adults' socioeconomic disparities in preventive care utilization. We aimed to explore household income disparities in the use of different types of health screening services among university students in Korea.This cross-sectional study used a web-based self-administered survey of students at a university in Korea from January to February 2013. To examine the associations between household income levels and health screening service use within the past 2 years, odds ratios (ORs) and 95% confidence intervals (CIs) were estimated using logistic regression with adjustment for various covariables.Of 2479 participants, 45.5% reported using health screening services within 2 years (university-provided screening 32.9%, private sector screening 16.7%, and both 4.1%). Household income levels were not significantly associated with overall rates of health screening service use with a multivariable-adjusted OR (95% CI) in the lowest versus highest income group of 1.12 (0.87-1.45, Ptrend = 0.35). However, we found significantly different associations in specific types of utilized screening services by household income levels. The multivariable-adjusted OR (95% CI) of university-provided health screening service use in the lowest versus highest income level was 1.74 (1.30-2.34; Ptrend income level was 0.45 (0.31-0.66; Ptrend income groups among university students in Korea, although overall rates of health screening service use were similar across income levels. Low-income students were more likely to use university-provided health screening services, and less likely to use private sector screening services. To ensure appropriate preventive care delivery for young adults and to address disparities in disadvantaged groups, the expansion of medical insurance coverage for preventive health care, establishment of a usual source of care, focusing on

  7. Mini-grid based off-grid electrification to enhance electricity access in developing countries: What policies may be required?

    Bhattacharyya, Subhes C.; Palit, Debajit

    2016-01-01

    With 1.2 billion people still lacking electricity access by 2013, electricity access remains a major global challenge. Although mini-grid based electrification has received attention in recent times, their full exploitation requires policy support covering a range of areas. Distilling the experience from a five year research project, OASYS South Asia, this paper presents the summary of research findings and shares the experience from four demonstration activities. It suggests that cost-effective universal electricity service remains a challenge and reaching the universal electrification target by 2030 will remain a challenge for the less developed countries. The financial, organisational and governance weaknesses hinder successful implementation of projects in many countries. The paper then provides 10 policy recommendations to promote mini-grids as a complementary route to grid extension to promote electricity access for successful outcomes. - Highlights: •The academic and action research activities undertaken through OASYS South Asia Project are reported. •Evidence produced through a multi-dimensional participatory framework supplemented by four demonstration projects. •Funding and regulatory challenges militate against universal electrification objectives by 2030. •Innovative business approaches linking local mini-grids and livelihood opportunities exist. •Enabling policies are suggested to exploit such options.

  11. EVALUATION OF UTILIZING SERVICE ORIENTED ARCHITECTURE AS A SUITABLE SOLUTION TO ALIGN UNIVERSITY MANAGEMENT INFORMATION SYSTEMS AND LEARNING MANAGEMENT SYSTEMS

    A. M. RIAD

    2009-10-01

    Full Text Available To help universities achieve their goals, it is important to align managerial functionalities side by side with educational aspects. Universities consume University Management Information Systems (UMIS to handle managerial aspects as they do with Learning Management Systems (LMS to achieve learning objectives. UMIS advances LMS by decades and has reached stable and mature consistency level. LMS is the newly acquired solution in Universities; compared to UMIS, and so adopting LMSs in universities can be achieved via three different deployment approaches. First approach believes in LMS ability to replace UMIS and performing its functionalities. Second approach presents the idea of extending UMIS to include LMS functionalities. Third approach arises from the shortages of the two proposed approaches and present integration between both as the appropriate deployment approach. Service Oriented Architecture (SOA is a design pattern that can be used as a suitable architectural solution to align UMIS and LMS. SOA can be utilized in universities to overcome some of information systems’ challenges like the integration between UMIS and LMS. This paper presents the current situation at Mansoura University; Egypt, presents integration as the most suitable solution, and evaluates three different implementation techniques: Dynamic Query, Stored Procedure, and Web services. Evaluation concludes that though SOA enhanced many different aspects of both UMIS and LMS; and consequently university overall. It is not recommended to adopt SOA via Web services as the building unit of the system, but as the interdisciplinary interface between systems.

  12. Safe Grid

    Chow, Edward T.; Stewart, Helen; Korsmeyer, David (Technical Monitor)

    2003-01-01

    The biggest users of GRID technologies came from the science and technology communities. These consist of government, industry and academia (national and international). The NASA GRID is moving into a higher technology readiness level (TRL) today; and as a joint effort among these leaders within government, academia, and industry, the NASA GRID plans to extend availability to enable scientists and engineers across these geographical boundaries collaborate to solve important problems facing the world in the 21 st century. In order to enable NASA programs and missions to use IPG resources for program and mission design, the IPG capabilities needs to be accessible from inside the NASA center networks. However, because different NASA centers maintain different security domains, the GRID penetration across different firewalls is a concern for center security people. This is the reason why some IPG resources are been separated from the NASA center network. Also, because of the center network security and ITAR concerns, the NASA IPG resource owner may not have full control over who can access remotely from outside the NASA center. In order to obtain organizational approval for secured remote access, the IPG infrastructure needs to be adapted to work with the NASA business process. Improvements need to be made before the IPG can be used for NASA program and mission development. The Secured Advanced Federated Environment (SAFE) technology is designed to provide federated security across NASA center and NASA partner's security domains. Instead of one giant center firewall which can be difficult to modify for different GRID applications, the SAFE "micro security domain" provide large number of professionally managed "micro firewalls" that can allow NASA centers to accept remote IPG access without the worry of damaging other center resources. The SAFE policy-driven capability-based federated security mechanism can enable joint organizational and resource owner approved remote

    With much higher levels of distributed energy resources - variable generation, energy storage, and controllable loads just to mention a few - being deployed into power systems, the data deluge from pervasive metering of energy grids, and the shaping of multi-level ancillary-service markets, current frameworks to monitoring, controlling, and optimizing large-scale energy systems are becoming increasingly inadequate. This position paper outlines the concept of 'Autonomous Energy Grids' (AEGs) - systems that are supported by a scalable, reconfigurable, and self-organizing information and control infrastructure, can be extremely secure and resilient (self-healing), and self-optimize themselves in real-time for economic and reliable performance while systematically integrating energy in all forms. AEGs rely on scalable, self-configuring cellular building blocks that ensure that each 'cell' can self-optimize when isolated from a larger grid as well as partaking in the optimal operation of a larger grid when interconnected. To realize this vision, this paper describes the concepts and key research directions in the broad domains of optimization theory, control theory, big-data analytics, and complex system modeling that will be necessary to realize the AEG vision.

  15. Earth Systems Science Curriculum Choices for Pre-Service Teachers at San Jose State University

    Messina, P.; Metzger, E. P.

    2008-12-01

    San José State University was a member of the original ESSEA consortium (2003-05), and it continues its participation with the broadening ESSEA community. Having hosted the original Middle- and High School Teachers' ESSEA courses, the Geology Department and Program in Science Education have maintained their commitments toward supporting pre- and in-service teachers in geoscience concept competency and effective pedagogy. We have witnessed an encouraging trend in the numbers of K-8 (multiple subject) pre-service teachers who have enrolled in our in-house ESSEA-inspired course: Geology 103 (Earth Systems and the Environment). We have also seen an influx of prospective secondary (single subject) teachers seeking credentials in non- geoscience disciplines. California teacher credentialing requirements, especially when layered on the increasing demands of major fields of study and the California State University System's hefty General Education mandates, give prospective teachers little latitude in their academic programs. Geology 103 was developed to satisfy three logistical objectives: to comply with "geoscience content competency" as defined by the California Commission on Teacher Credentialing (CCTC); to fulfill one of the CSU's upper-division General Education requirements, and to develop science process skills in a population that may never have had similar prior opportunities. The course is offered in two modalities: online and on-campus. The Web-based sections are currently comparing the relative effectiveness of two dissimilar online learning modalities and assessments: one delivers video/audio/animated "podcasts," while the other requires student involvement through interactive Flash media. The course is taught by professors with joint appointments in the Department of Geology and Program in Science Education, and by current and former classroom teachers to ensure that geoscience content knowledge is achieved through inquiry, systems analyses, and other

  18. A study of issues in administering library services to nursing studies students at Glasgow Caledonian University.

    Crawford, John

    2002-06-01

    Glasgow Caledonian University has had a Scottish Office pre-registration nursing and midwifery contract since 1996. Nursing studies students seemed dissatisfied with the library service and there were frequent complaints. A major study was undertaken during 2000 consisting of: an initial lis-link enquiry, separate analysis of returns from nursing studies students of the Library's annual general satisfaction survey (conducted every February), separate analysis of returns from nursing studies students of the Library's opening hours planning survey, and four focus groups held in October 2000. These studies showed the concerns of nursing studies students to be similar to other students but more strongly felt. The four main issues were textbook availability, journal availability, opening hours and staff helpfulness. Working conditions, placement requirements, study requirements and domestic circumstances were all found to be important factors. IT skill levels tended to be low but there is a growing appreciation of the need for training in this area. Concluded that: Library's services to nursing studies students have become enmeshed with the problems of delivery and assessment of education for nurses. Greatly extended opening hours are essential including evening opening during vacations. The problem of access to textbooks is so severe that conventional solutions are not going to work. Programmes of core text digitization and the promotion of e-books are needed. Reciprocal access programmes with local hospital libraries is essential.

  19. Incorporating Service-Learning, Technology, and Research Supportive Teaching Techniques into the University Chemistry Classroom

    Saitta, E. K. H.; Bowdon, M. A.; Geiger, C. L.

    2011-12-01

    Technology was integrated into service-learning activities to create an interactive teaching method for undergraduate students at a large research institution. Chemistry students at the University of Central Florida partnered with high school students at Crooms Academy of Information Technology in interactive service learning projects. The projects allowed UCF students to teach newly acquired content knowledge and build upon course lecture and lab exercises. Activities utilized the web-conferencing tool Adobe Connect Pro to enable interaction with high school students, many of whom have limited access to supplemental educational opportunities due to low socioeconomic status. Seventy chemistry I students created lessons to clarify high school students' misconceptions through the use of refutational texts. In addition, 21 UCF students enrolled in the chemistry II laboratory course acted as virtual lab partners with Crooms students in an interactive guided inquiry experiment focused on chemical kinetics. An overview of project's design, implementation, and assessments are detailed in the case study and serve as a model for future community partnerships. Emerging technologies are emphasized as well as a suggested set of best practices for future projects.

    Horii, S.C.; Muraki, A.; Mun, S.K.; Clark, L.; Schellinger, M.D.; Mallon-Ingeholm, M.L.

    1989-01-01

    A complete image management and communications system has been installed at Georgetown University Hospital (GUH). The network is based on the AT ampersand T CommView System. In the Neuroradiology Division, this network supports a multiscreen workstation with access to multiple imaging modalities such as CT and MRI from both the hospital and a remote imaging center. In addition, the radiologist can access these images from various workstations located throughout the hospital as well as from remote sites such as the home. Among the radiology services supported by the network, neuroradiology has the greatest need for such a system with extensive daily requirements involving the remote imaging center and on-line consultation around the clock. By providing neuroradiology with all available communication links, the radiologist can monitor, diagnose, and consult. The efficiency and effectiveness of the system's capabilities with regard to remote and teleradiology (RVS) operations have been studied for the neuroradiology service. This paper discusses the current clinical acceptance and use, problems in implementation, and ways these difficulties are being surmounted

  1. UniPrime2: a web service providing easier Universal Primer design.

    Boutros, Robin; Stokes, Nicola; Bekaert, Michaël; Teeling, Emma C

    2009-07-01

    The UniPrime2 web server is a publicly available online resource which automatically designs large sets of universal primers when given a gene reference ID or Fasta sequence input by a user. UniPrime2 works by automatically retrieving and aligning homologous sequences from GenBank, identifying regions of conservation within the alignment, and generating suitable primers that can be used to amplify variable genomic regions. In essence, UniPrime2 is a suite of publicly available software packages (Blastn, T-Coffee, GramAlign, Primer3), which reduces the laborious process of primer design, by integrating these programs into a single software pipeline. Hence, UniPrime2 differs from previous primer design web services in that all steps are automated, linked, saved and phylogenetically delimited, only requiring a single user-defined gene reference ID or input sequence. We provide an overview of the web service and wet-laboratory validation of the primers generated. The system is freely accessible at: http://uniprime.batlab.eu.

  2. Development of an e-learning package on Service-Learning for university teachers: experience from Hong Kong.

    Shek, Daniel T L; Chan, Stephen C F

    2013-01-01

    To help university teachers to understand Service-Learning and develop Service-Learning subjects, a 3-h+ e-learning package was developed at The Hong Kong Polytechnic University (PolyU). There are seven units in this e-learning package: introduction session (Unit 1), what is Service-Learning? (Unit 2), impact and benefits of Service-Learning (Unit 3), myths and positive attitudes toward Service-Learning (Unit 4), developing a Service-Learning subject at PolyU (Unit 5), self-reflection about Service-Learning (Unit 6), and concluding session (Unit 7). To understand the views of the users on the e-learning package, the package was offered before formal launching. For the first offering, three focus group sessions were held. Results showed that the users were satisfied with the structural arrangement of the e-learning package and agreed that the e-learning package was useful for them to understand more about Service-Learning. For the second offering, colleagues were generally satisfied with the e-learning package and demonstrated gain in knowledge on Service-Learning. Suggestions for improvement were noted.

  3. Effects of Service Quality and Customer Satisfaction on Repurchase Intention in Restaurants on University of Cape Coast Campus

    Ishmael Mensah

    2018-05-01

    Full Text Available This study sought to examine the effects of service quality and customer satisfaction on the repurchase intentions of customers of restaurants on University of Cape Coast Campus. The survey method was employed involving a convenient sample of 200 customers of 10 restaurants on the University of Cape Coast Campus. A modified DINESERV scale was used to measure customers’ perceived service quality. The results of the study indicate that four factors accounted for 50% of the variance in perceived service quality, namely; responsiveness-assurance, empathy-equity, reliability and tangibles. Service quality was found to have a significant effect on customer satisfaction. Also, both service quality and customer satisfaction had significant effects on repurchase intention. However, customer satisfaction could not moderate the effect of service quality on repurchase intention. This paper adds to the debate on the dimensions of service quality and provides evidence on the effects of service quality and customer satisfaction on repurchase intention in a campus food service context.

  6. A theoretical model to predict customer satisfaction in relation to service quality in selected university libraries in Sri Lanka

    Chaminda Jayasundara

    2009-01-01

    Full Text Available University library administrators in Sri Lanka have begun to search for alternative ways to satisfy their clientele on the basis of service quality. This article aims at providing a theoretical model to facilitate the identification of service quality attributes and domains that may be used to predict customer satisfaction from a service quality perspective. The effectiveness of existing service quality models such as LibQUAL, SERVQUAL and SERVPREF have been questioned. In that regard, this study developed a theoretical model for academic libraries in Sri Lanka based on the disconfirmation and performance-only paradigms. These perspectives were considered by researchers to be the core mechanism to develop service quality/customer satisfaction models. The attributes and domain identification of service quality was carried out with a stratified sample of 263 participants selected from postgraduate and undergraduate students and academic staff members from the faculties of Arts in four universities in Sri Lanka. The study established that responsiveness, supportiveness, building environment, collection and access, furniture and facilities, technology, Web services and service delivery were quality domains which can be used to predict customer satisfaction. The theoretical model is unique in its domain structure compared to the existing models. The model needs to be statistically tested to make it valid and parsimonious.

    In a smart grid, data and information are transported, transmitted, stored, and processed with various stakeholders having to cooperate effectively. Furthermore, personal data is the key to many smart grid applications and therefore privacy impacts have to be taken into account. For an effective smart grid, well integrated solutions are crucial and for achieving a high degree of customer acceptance, privacy should already be considered at design time of the system. To assist system engineers in early design phase, frameworks for the automated privacy evaluation of use cases are important. For evaluation, use cases for services and software architectures need to be formally captured in a standardized and commonly understood manner. In order to ensure this common understanding for all kinds of stakeholders, reference models have recently been developed. In this paper we present a model-driven approach for the automated assessment of such services and software architectures in the smart grid that builds on the standardized reference models. The focus of qualitative and quantitative evaluation is on privacy. For evaluation, the framework draws on use cases from the University of Southern California microgrid.

  8. Need assessment of staffs' welfare services at tehran university of medical sciences: a cross-sectional study.

    Dehghan, Reza; Mafimoradi, Shiva; Hadi, Mohammad

    2015-01-01

    Reviewing the human resources management literature shows an absence of attention given to the employee's benefits. Taking a look at functions of the Tehran University of Medical Sciences' wellbeing services system, it uncovers a gap between employees' real needs and what is delivered to meet their needs. So it requires an improved comprehensive system for delivering wellbeing services (financial, insurance, health care services, educational and training services, etc). Wellbeing need assessment can helps planners to identify vital needs of employee and response to them effectively. Moreover it can be used to evaluate the effectiveness of the current services which are delivered. Thus, the aim of this study is to assess wellbeing services of staffs working in TUMS to (1) evaluate the satisfactory rate of services which are delivered, and (2) exploring those wellbeing needs which were not fulfilled by the organization. Being a cross-sectional and analytic-descriptive survey including 98 responding participants, it is conducted by a questionnaire collecting employees' demographic information, their satisfactory rate of the implemented services, and determines unfulfilled wellbeing needs which were not already covered. Results indicated that services related to financial, educational, non-financial, insurance, occupational health and tourism/recreational services were the most satisfactory services successively. 'Staff's unwillingness to receive services' and 'poor announcement' (unawareness on the wellbeing services),' were found to be the most frequent reasons for not receiving the existing wellbeing services. To increase the satisfaction rate and responsiveness to the real needs of the staff, the current delivery system of wellbeing services in the TUMS should be redesigned by defining new wellbeing packages.

    2010-09-01

    Full Text Available During the last years, dramatic changes in the electronic publishing landscape have created new roles and changed the traditional ones. Presently, some libraries have capitalised on their experience and knowledge in information technology and electronic publishing to undertake such activities, while at the same time they spearhead the campaign for Open Access spreading within academic communities. The Library & Information Centre (LIC of the University of Patras (UoP, Greece, has been playing an active role in promoting Open Access (OA in Greece. Since 2007, LIC has been experimenting with OA publishing practices and tools within the framework of various R&D projects. Two of the major results of these efforts are the ‘Pasithee’ e-publishing platform and the ‘Dexamene’ digital archive for Greek scholarly journals. Both platforms are based on OJS-Open Journal Systems e-publishing software. The two facilities were appropriately modified to meet the LIC’s publishing and archiving requirements respectively. Currently two journals are being hosted on each platform and all four are from the Humanities. The LIC is negotiating with more publishers and editorial teams to host their journals. In this article we focus on: - technical and managerial key issues of the development and operation phases, - services and procedures, - the business model, - technological, procedural and legal issues and problems that were encountered when working together with publishers, editors and authors, and - future plans for improving and upgrading our e-publishing services into an integrated institutional platform to cover all kinds of publications and data types (monographs, conference proceedings, teaching material, bulletins, magazines etc.. The article concludes with a succinct presentation of the Directory of Greek Digital Resources, a pilot infrastructure developed by the LIC which indexes and presents digital publishing initiatives in Greece and aims to

  13. Professionalization and retention outcomes of a university-service mentoring program partnership.

    Latham, Christine L; Ringl, Karen; Hogan, Mikel

    2011-01-01

    With the use of a university-service partnership to introduce mentoring and shared governance, the aim of this study was to evaluate the effect of these interventions on nurse perceptions of the supportive culture of the workplace environment, professional skill development, decisional involvement, and retention and vacancy rates. A nonequivalent pretest-posttest, noncontrol group design was used with mentors of newly hired mentees to evaluate their workplace perspectives following mentor classes, ongoing mentor support, and a formal mentor-management workforce governance board. A convenience sample of 89 RNs from two acute care facilities attended mentoring and professionalization classes and worked with 109 mentees over 1-3 years. Mentors reported improved teamwork and the ability to deal with conflict but wanted more administrative oversight of the quality and scope of practice of support staff and additional interdepartmental collaboration. One hospital's vacancy rate decreased by 80%, and the other facility's retention rate improved by 21%. The data suggest that a mentor program with comprehensive education and mentor-management alliances through formal workforce environment governance enhances professionalization of frontline nurses and helps sustain a positive, constructive workplace environment. Mentoring classes on communication and cultural sensitivity skills and other leadership concepts, followed by mentor support and mentor-administrative forums, have positive implications for sustained improvement of a supportive culture as perceived by hospital-based RNs and new nurse graduates.

  10. University of Global Health Equity’s Contribution to the Reduction of Education and Health Services Rationing

    Agnes Binagwaho

    2017-08-01

    Full Text Available The inadequate supply of health workers and demand-side barriers due to clinical practice that heeds too little attention to cultural context are serious obstacles to achieving universal health coverage and the fulfillment of the human rights to health, especially for the poor and vulnerable living in remote rural areas. A number of strategies have been deployed to increase both the supply of healthcare workers and the demand for healthcare services. However, more can be done to improve service delivery as well as mitigate the geographic inequalities that exist in this field. To contribute to overcoming these barriers and increasing access to health services, especially for the most vulnerable, Partners In Health (PIH, a US non-governmental organization specializing in equitable health service delivery, has created the University of Global Health Equity (UGHE in a remote rural district of Rwanda. The act of building this university in such a rural setting signals a commitment to create opportunities where there have traditionally been few. Furthermore, through its state-of-the-art educational approach in a rural setting and its focus on cultural competency, UGHE is contributing to progress in the quest for equitable access to quality health services.

  11. Using focus groups to investigate service quality determinants for customer satisfaction in selected university libraries in Sri Lanka

    Chaminda Jayasundara

    2010-01-01

    Full Text Available This study aimed at establishing service quality determinants which may affect customer satisfaction in university libraries in Sri Lanka. Using the literature, 113 service quality determinants were identified. These were then reviewed by eight focus groups in four different universities. Forty of the determinants were perceived to be applicable to their context. The participants also added 14 quality requirements which they thought were not provided for in the list. Finally, the content and face validity of the 54 determinants were evaluated by a panel of experts who ultimately reduced them to 50. This study recommends the use of the identified quality determinants by library administrators and policymakers in the higher education sector in Sri Lanka to gauge the levels of customer satisfaction and assure quality of service.

    2004-01-01

    The paper will report on the progress of an ongoing EU project called GRACE - Grid Search and Categorization Engine (http://www.grace-ist.org). The project participants are CERN, Sheffield Hallam University, Stockholm University, Stuttgart University, GL 2006 and Telecom Italia. The project started in 2002 and will finish in 2005, resulting in a Grid based search engine that will search across a variety of content sources including a number of electronic thesis and dissertation repositories. The Open Archives Initiative (OAI) is expanding and is clearly an interesting movement for a community advocating open access to ETD. However, the OAI approach alone may not be sufficiently scalable to achieve a truly global ETD Digital Library. Many universities simply offer their collections to the world via their local web services without being part of any federated system for archiving and even those dissertations that are provided with OAI compliant metadata will not necessarily be picked up by a centralized OAI Ser...

  20. Virtual in-service training from the librarians' point of view in libraries of medical sciences universities in Tehran

    Mohaghegh, Niloofar; Raiesi Dehkordi, Puran; Alibeik, MohammadReza; Ghashghaee, Ahmad; Janbozorgi, Mojgan

    2016-01-01

    Background: In-service training courses are one of the most available programs that are used to improve the quantity and quality level of the staff services in various organizations, including libraries and information centers. With the advent of new technologies in the field of education, the problems and shortcomings of traditional in-service training courses were replaced with virtual ones. This study aimed to evaluate the virtual in-service training courses from the librarians' point of view in libraries of state universities of medical sciences in Tehran. Methods: This was a descriptive- analytical study. The statistical population consisted of all librarians at libraries of universities of medical sciences in Tehran. Out of 103 librarians working in the libraries under the study, 93 (90%) participated in this study. Data were collected, using a questionnaire. Results: The results revealed that 94/6% of librarians were satisfied to participate in virtual in-service training courses. In this study, only 45 out of 93 participants said that the virtual in-service courses were held in their libraries. Of the participants, 75.6% were satisfied with the length of training courses, and one month seemed to be adequate time duration for the librarians to be more satisfied. The satisfaction level of the individuals who participated in in-service courses of the National Library was moderate to high. A total of 84.4% participants announced that the productivity level of the training courses was moderate to high. The most important problem with which the librarians were confronted in virtual in-service training was the "low speed of the internet and inadequate computer substructures". Conclusion: Effectiveness of in-service training courses from librarians’ point of view was at an optimal level in the studied libraries. PMID:28491833

The most important problem with which the librarians were confronted in virtual in-service training was the "low speed of the internet and inadequate computer substructures". Conclusion: Effectiveness of in-service training courses from librarians' point of view was at an optimal level in the studied libraries.

    Client characterization is an important step in evaluating the services offered by campus counseling and mental health centers and in their further planning and development. The objectives here were to describe reported complaints and demographics among students who sought counseling/mental healthcare at a Brazilian campus mental health service over a 17-year period and to compare these characteristics with those of the general university student body. Retrospective study at the Psychological and Psychiatric Service for Students (SAPPE), Universidade Estadual de Campinas (Unicamp). The participants were all of the 2,194 students who sought counseling/mental health care at SAPPE from 1987 to 2004. Information was obtained from clients clinical charts. Unicamps database was consulted for general information on its students. The findings indicated overrepresentation, among the clients, of undergraduates, female students, students from Brazilian states other than São Paulo, students living in the campus residence hall and those whose main source of income was a scholarship grant. We also found overrepresentation of Humanities and Arts students among the clients. The most frequently reported complaints were difficulties in interpersonal relationships, family conflicts and poor academic performance. Course level (undergraduate or postgraduate), study field, living in a university residential facility and reliance on a scholarship grant were found to influence the behavior of seeking mental health counseling among Brazilian university students in this study. Course level was found to influence the pattern of complaints reported at first contact with the mental health service.

    The study population were all librarians working in the Reference Services, information and Public services in Libraries of Ferdowsi University of Mashhad (32 person. Interviews were conducted with one of the administrative staff at the Central Library. The checklist was completed with the help of the head of each library. The findings showed that about 35% of reference librarians using less electronic reference services. in this field, Others evaluate themselves as moderate. And all the librarians (100 percent were mentioned that offer of electronic reference services is necessary. Meanwhile, only 28% believed that librarians have the Technology skills and nearly 50% believe that they have the searching skills. In this regard, more than 60% of librarians said they have suitable skills. Based on the finding and the gap between present and ideal situation it seems that the usage rate of technology in its ideal form has the deepest gap and with the librarian's individual skills has not it.

    We introduce molecularevolution.org, a publicly available gateway for high-throughput, maximum-likelihood phylogenetic analysis powered by grid computing. The gateway features a garli 2.0 web service that enables a user to quickly and easily submit thousands of maximum likelihood tree searches or bootstrap searches that are executed in parallel on distributed computing resources. The garli web service allows one to easily specify partitioned substitution models using a graphical interface, and it performs sophisticated post-processing of phylogenetic results. Although the garli web service has been used by the research community for over three years, here we formally announce the availability of the service, describe its capabilities, highlight new features and recent improvements, and provide details about how the grid system efficiently delivers high-quality phylogenetic results. © The Author(s) 2014.

    2008-01-01

    Grid computing has attracted worldwide attention in a variety of applications like Health Care. In this paper we identified the Grid services that could facilitate the integration and interoperation of Health Care data and frameworks world-wide. While many of the current Health Care Grid projects address issues such as data location and description on the Grid and the security aspects, the problems connected to data storage, integrity, preservation and distribution have been neglected. We describe the currently available Grid storage services and protocols that can come in handy when dealing with those problems. We further describe a Grid infrastructure to build a cooperative Health Care environment based on currently available Grid services and a service able to validate it.

  8. First Thuesday - CERN, The Grid gets real

    Robertson, Leslie

    2003-01-01

    A few years ago, "the Grid" was just a vision dreamt up by some computer scientists who wanted to share processor power and data storage capacity between computers around the world - in much the same way as today's Web shares information seamlessly between millions of computers. Today, Grid technology is a huge enterprise, involving hundreds of software engineers, and generating exciting opportunities for industry. "Computing on demand", "utility computing", "web services", and "virtualisation" are just a few of the buzzwords in the IT industry today that are intimately connected to the development of Grid technology. For this third First Tuesday @CERN, the panel will survey some of the latest major breakthroughs in building international computer Grids for science. It will also provide a snapshot of Grid-related industrial activities, with contributions from both major players in the IT sector as well as emerging Grid technology start-ups.

  9. Case study : power distribution PBR plans of National Grid USA

    Hill, T.

    2001-01-01

    This power point presentation described the progressive approach taken by the Northeastern United States towards electric power restructuring and performance based ratemaking (PBR) with reference to National Grid USA and the NEES tradition of pursuing regulatory matters. The catalyst for change was the NEES acquisition of EUA (and National Grid USA acquisition of NEES). Another catalyst for change was the desire to merge operating companies and consolidate rates. This paper described the settlement negotiations of the New England Process with reference to meeting the customer's desire for lower electricity prices and rate stability.The paper also described a multi-year PBR-based plan proposed for Niagara Mohawk which offers incentives for both cost efficiency and service quality. It was concluded that PBR is a sound basis for optimizing customer and shareholder benefits. It was emphasized that while PBR has universal application, detailed implementation must be sensitive to local issues and priorities. tabs., figs

  10. Replica consistency in a Data Grid

    2004-01-01

    A Data Grid is a wide area computing infrastructure that employs Grid technologies to provide storage capacity and processing power to applications that handle very large quantities of data. Data Grids rely on data replication to achieve better performance and reliability by storing copies of data sets on different Grid nodes. When a data set can be modified by applications, the problem of maintaining consistency among existing copies arises. The consistency problem also concerns metadata, i.e., additional information about application data sets such as indices, directories, or catalogues. This kind of metadata is used both by the applications and by the Grid middleware to manage the data. For instance, the Replica Management Service (the Grid middleware component that controls data replication) uses catalogues to find the replicas of each data set. Such catalogues can also be replicated and their consistency is crucial to the correct operation of the Grid. Therefore, metadata consistency generally poses stricter requirements than data consistency. In this paper we report on the development of a Replica Consistency Service based on the middleware mainly developed by the European Data Grid Project. The paper summarises the main issues in the replica consistency problem, and lays out a high-level architectural design for a Replica Consistency Service. Finally, results from simulations of different consistency models are presented

    Clinical trials play a crucial role in testing new drugs or devices in modern medicine. Medical imaging has also become an important tool in clinical trials because images provide a unique and fast diagnosis with visual observation and quantitative assessment. A typical imaging-based clinical trial consists of: 1) A well-defined rigorous clinical trial protocol, 2) a radiology core that has a quality control mechanism, a biostatistics component, and a server for storing and distributing data and analysis results; and 3) many field sites that generate and send image studies to the radiology core. As the number of clinical trials increases, it becomes a challenge for a radiology core servicing multiple trials to have a server robust enough to administrate and quickly distribute information to participating radiologists/clinicians worldwide. The Data Grid can satisfy the aforementioned requirements of imaging based clinical trials. In this paper, we present a Data Grid architecture for imaging-based clinical trials. A Data Grid prototype has been implemented in the Image Processing and Informatics (IPI) Laboratory at the University of Southern California to test and evaluate performance in storing trial images and analysis results for a clinical trial. The implementation methodology and evaluation protocol of the Data Grid are presented.

    Patient satisfaction, one of the main components of quality of care, is a crucial phenomenon for the overall health care delivery system. Even though a number of studies have been conducted about patient satisfaction in different health services, studies in radiology services are flimsy in Ethiopia. This study aimed at assessing patient satisfaction towards radiological service and associated factors in Hawassa University Teaching and Referral hospital. An institution based cross-sectional study was conducted among 321 adult patients presented for radiological service in the study area using stratified sampling technique. Patient satisfaction was measured using SERVQUAL (Service Quality) tool that consisted of seven items: accessibility, quality of radiological service, courtesy of radiology staff, existence of good communication with service provider and desk worker, physical environment and privacy technique. Exit interviews of patients were conducted using a structured and pretested questionnaire. Data was collected by three grade ten completed trained data collectors from May 12 to May 28, 2016. Multiple logistic regressions were used to identify independent factors associated with patient satisfaction on radiological services using SPSS version 21. The overall patient satisfaction towards radiological service was 71.6%. Satisfaction to accessibility of the service was 84.5% while it was 80.6% to courtesy of the staff. Similarly, 81.6% reported satisfied with quality of the service and 59.4% and 71% of reported satisfied with physical environment and radiological service provider respectively. On the other hand, 99.7% of the respondents were dissatisfied with privacy of the service. The study revealed that patients who attended primary school (AOR = 0.317, 95% CI: 0.11-0.88), unemployed patients (AOR = 0.067, 95% CI: 0.007-0.622) and patients who had short waiting time to enter into examination room less than one hour (AOR = 4.12, 95% CI: 1.4-11.62) were

    Grid Information Systems are mission-critical components in today's production grid infrastructures. They enable users, applications and services to discover which services exist in the infrastructure and further information about the service structure and state. It is therefore important that the information system components themselves are functioning correctly and that the information content is reliable. Grid Status (GStat) is a tool that monitors the structural integrity of the EGEE info...

    GRID technology, with initiatives like the GGF, will have the potential to allow both competition and interoperability not only among applications and toolkits, but also among implementations of key services. The pyramid of eHealth interoperability should be achieved from standards in communication and data security, storage and processing, to the policy initiatives, including organizational protocols, financing procedures, and legal framework. The open challenges for GRID use in clinical fields illustrate the potential of the combination of grid technologies with medical routine into a wider interoperable framework. The Telemedicine Alliance is a consortium (ESA, WHO and ITU), initiated in 2002, in building a vision for the provision of eHealth to European citizens by 2010. After a survey with more that 50 interviews of experts, interoperability was identified as the main showstopper to eHealth implementation. There are already several groups and organizations contributing to standardization. TM-Alliance is supporting the "e-Health Standardization Coordination Group" (eHSCG). It is now, in the design and development phase of GRID technology in Health, the right moment to act with the aim of achieving an interoperable and open framework. The Health area should benefit from the initiatives started at the GGF in terms of global architecture and services definitions, as well as from the security and other web services applications developed under the Internet umbrella. There is a risk that existing important results of the standardization efforts in this area are not taken up simply because they are not always known.

    The use of Web Services to enable programmatic access to on-line bioinformatics is becoming increasingly important in the Life Sciences. However, their number, distribution and the variable quality of their documentation can make their discovery and subsequent use difficult. A Web Services registry with information on available services will help to bring together service providers and their users. The BioCatalogue (http://www.biocatalogue.org/) provides a common interface for registering, browsing and annotating Web Services to the Life Science community. Services in the BioCatalogue can be described and searched in multiple ways based upon their technical types, bioinformatics categories, user tags, service providers or data inputs and outputs. They are also subject to constant monitoring, allowing the identification of service problems and changes and the filtering-out of unavailable or unreliable resources. The system is accessible via a human-readable 'Web 2.0'-style interface and a programmatic Web Service interface. The BioCatalogue follows a community approach in which all services can be registered, browsed and incrementally documented with annotations by any member of the scientific community.

    Full Text Available In Korea, a national university admission is made based on a variety of factors like Grade Point Average(GPA, Statement of Purpose(SOP, Letters of Recommendation, as well as other achievement records and/or descriptions of specific qualifications. In reviewing applications, the admissions committee considers GPA, SOP, recommendation letters and other factors are also taken into consideration in the interview process. An interview test is designed to measure the overall ability of pre-service teachers, particularly focusing on their character and nature. Thus, the purpose of this study is intended to understand the admission processes of a national university in Korea, and to design the interview test questions to choose the ideal pre-service teachers who are to work in the public elementary school after graduation. In order to answer this question, a survey questionnaire was distributed to 478 college students and then results were collected and analysed.

    2014-01-01

    It is important to ensure consumer acceptance in a smart grid since the ultimate deployment of the smart grid depends on the end users' acceptance of smart grid products and services such as smart meters and advanced metering services. We examine how residential consumers perceive the smart grid and what factors influence their acceptance of the smart grid through a survey for electricity consumers in Korea. In this study, consumers' smart grid acceptance factors, including the perceived risk, were examined with the existing technology acceptance model suggested by Davis. This study has an implication that it has provided theoretical and empirical ground, based on which the policies to promote consumer participation in the deployment of the smart grid can be developed. Since there are few studies on the policies from the perspective of the smart grid users, this study will contribute directly to the development of the strategy to ensure the acceptance of the smart grid. - Highlights: • We examine what factors influence electricity consumers' smart grid acceptance. • We test the smart grid technology acceptance model including the perceived risk as a main factor. • The importance of consumer education and public relations of the smart grid has been confirmed. • Another shortcut to ensure the acceptance of the smart grid is to mitigate the anxiety about the risk in the use of the smart grid

    There are limited data on the frequency of foregone health service use in defined populations. Here we describe Thai patterns of health service use, types of health insurance used and reports of foregone health services according to geo-demographic and socioeconomic characteristics. Data on those who considered they had needed but not received health care over the previous year were obtained from a national cohort of 87,134 students from the Sukhothai Thammathirat Open University (STOU). The cohort was enrolled in 2005 and was largely made up of young and middle-age adults living throughout Thailand. Among respondents, 21.0% reported use of health services during the past year. Provincial/governmental hospitals (33.4%) were the most attended health facilities in general, followed by private clinics (24.1%) and private hospitals (20.1%). Health centers and community hospitals were sought after in rural areas. The recently available government operated Universal Coverage Scheme (UCS) was popular among the lower income groups (13.6%), especially in rural areas. When asked, 42.1% reported having foregone health service use in the past year. Professionals and office workers frequently reported 'long waiting time' (17.1%) and 'could not get time off work' (13.7%) as reasons, whereas manual workers frequently noted it was 'difficult to travel' (11.6%). This information points to non-financial opportunity cost barriers common to a wide array of Thai adults who need to use health services. This issue is relevant for health and workplace policymakers and managers concerned about equitable access to health services.
