The Grid computing vision promises to provide the needed platform for a new and more demanding range of applications. For this promise to become true, a number of hurdles, including the design and deployment of adequate resource management and information services, need to be overcome.

In the past, various virtual Frisch-grid designs have been proposed for cadmium zinc telluride (CZT) and other compound semiconductor detectors. These include three-terminal, semi-spherical, CAPture, Frisch-ring, capacitive Frisch-grid and pixel devices (along with their modifications). Among them, the Frisch-grid design employing a noncontacting ring extended over the entire side surfaces of p...

Anticipating the future is a key motif of the brain, possibly supported by mental simulation of upcoming events. Rodent single-cell recordings suggest the ability of spatially tuned cells to represent subsequent locations. Grid-like representations have been observed in the human entorhinal cortex during virtual and imagined navigation. However, hitherto it remains unknown if grid-like represen...

The idea behind grid computing is to make multiple machines that may be in different physical locations, behave like they are one large virtual machine. In grid computing, the total work load is distributed among many computers which are linked together through some kind of local or global network topology. There is no restriction of work it could be of any type like mathematical calculations o...

A model for locating services in grid is described here. It integrates the Grid framework OGSA (Open Grid Services Architecture) [1], using VO (Virtual Organization) [2] concept to divide logic grid services into different organizations based on its establishing purpose and requirement on resources sharing and services providing. The CARP hash-based information caching mechanism and a hierarchy...

This paper presents a way to build a computational Grid for PVM programs. The Grid applies Jini to handle the dynamically changing set of participants, and to make the communication between Grid-clients and Grid-machines possible. In case of a PVM-Grid the grid-resources are Parallel Virtual Machines. Our system provides a high-level interface for them, which through the users can submit their ...
