Virtual learning has opened new vistas in meta-information handling. Large collections of portfolios and e-books, large communities of e-people and processes over widespread virtual campuses impose a new management strategy. The most appropriate solution for a global university is to use a grid architecture based on distributed warehouses in order to use its distributed processing power. This p...

Geospatial science is the science and art of acquiring, archiving, manipulating, analyzing, communicating, and utilizing spatially explicit data for understanding physical, biological, and social systems on the Earth’s surface or near the surface. In order to share distributed geospatial resources and facilitate the interoperability, the Open Geospatial Consortium (OGC), an industry-government-...

Today grid middleware is complex to be used, the development of grid-aware applications is errorprone and the Virtual Organization grid paradigm contrasts with traditional HPC optimisation strategies based on resource stability and known cost models of inter-node interaction patterns. The authors analyse several aspects of grid adaptivity, and identify 5 roles: the active resource/execution man...

Grid technologies and infrastructures facilitate distributed resource sharing and coordination in dynamic, heterogeneous, multi-institutional environments. A replica catalog is a Grid component that keeps replica locations of data objects and provides location transparency to data access. Replica selection is of great importance to data-intensive scientific computing targeted by many data Grid ...

Computational grid portals are becoming essential tools in automotive companies world-wide for managing compute resources for virtual engineering and design. Many automotive and associated manufacturing industries are taking initiatives for making the computing resources transparent from the integrated design environment. This paper illustrates how the grid portal technologies can fulfil these ...

The paper presents a Virtual Organization (VO) framework which incorporates wireless technologies support at the point of care in the clinical healthcare environment. It reflects the move to patient-centric healthcare given by multi-disciplinary care team collaborating in the patient’s treatment. The work sheds light into how VOs incorporating wireless technologies can meet the needs of the car...

The need to remain competitive in the open market forces companies to concentrate on their core competencies while searching for alliances when additional skills or resources are needed to fulfill business opportunities. The changing business situation of companies and customer needs have motivated researchers to introduce Virtual Organization (VO) idea. A Virtual Organization is always a form ...

The Use of ICT in business has changed views about traditional business. With VO, organizations with out physical, geographical, or structural constraint can collaborate with together in order to fulfill customer requests in a networked environment. This idea improves resource utilization, reduces development process and costs, and saves time. Virtual Organization (VO) is always a form of partn...

Grid Computing environments are mainly created to lead the shared use of different resources based on business/science needs. The way these resources are shared in terms of CPU cycles, storage capacity, software licenses, . . . is normally established by the availability of these resources out of the local administration context. Semantic Grid is the extension of Grid Computing with Semantic We...

Information Service is a key component of a Grid environment and crucial to the operation of a computational Grid. This paper presents an Information Service for a computational Grid Virtual Organization (VO). The main functionality of this Information Service is the provision of information essential for applications running on a computational Grid. This Information Service is a hierarchical s...
