Grid computing technology has become the most popular and mature way of distributed computing recently. At the same time, embedded system and System-on-Chip(SoC) architecture are becoming commonly used in calculation area, because of the low design cost and extensible architecture. These new technology provides a noval way to construct grid computing infrustructure with embedded system on SoC. ...

the paper tries to present an improved mathematical model for distribution companies (discos) in order to solve distribution network expansion planning (dnep) problems in the presence of certain resources of distributed generations (dgs) entitled small scale gas engines in the medium voltage grids. with the aim of minimizing investment and operation costs, the recommended model combines a compr...

there area lot of mobile computer devices with a variety of applications and users tend to use them more. due to the limitations of mobile devices, running most of the procedures are impossible. to resolve this problem, mobile devices can be connected to the grid, to use the facilities of grid. on the other hand the communication mechanisms are different for each device and they cannot be conne...

abstract: in this paper a control scheme for grid-connected operation mode and the island state of distributed generation is presented. in normal conditions, every inverter dg system in micro-grids to supply a preset power, normally operate in a constant current control mode. when micro-grids removed from the network, dg inverter of each system must recognize the island and change position to v...

Indian giant power system is facing the various problems. Due to these problems, the growth of electricity market is very slow. The present grid system in this country is incapable to handle these discrepancies. To handle these discrepancies and other typical snags in power system, there is a need to complete automation. Viewing these problems Smart Grid technologies is to be introduce/embedded...

In this paper we present design and development of the grid workflow system based on the semantic grid services. We will highlight the process of the discovery and composition of grid and web services into workflows and semantic technologies supporting the users during the workflow composition and evaluation of the results [13]. We will describe in detail the challenges of the design and develo...

P-Grid [1] is an efficient infrastructure to perform lookup and search operations in large-scale and highly dynamic peer-to-peer systems. P-Grid has been designed to account for several requirements and features of P2P systems. It provides a decentralized solution where adaptability to environmental conditions is a driving factor. On the one hand, P-Grid provides an efficient structured overlay...

Desktop grids are an emerging trend in grid computing. Interoperability and resource sharing between different desktop grid projects however is not yet solved. This paper presents an approach of organizing desktop grids in a hierarchy that makes it possible for lower-level desktop grids to acquire work from the higher level if they have spare resources available, thus building large-scale grid ...

The electricity economy and its excessive consumption have become one of the main concerns of the Iranian government for many years. This issue, along with recent droughts, shows the need to use renewable energy that is free and clean and does not require water. In addition, due to the high cost of cable-laying and maintenance of power lines, it is not at all an option at all distances over the...

The advent of hypertext brings with it associated problems of how best to present nonlinear texts. As yet, knowledge of readers' models of texts and their uses is limited. Repertory grid analysis offers an insightful method of examining these issues and gaining an understanding of the type of texts that exist in the readers' worlds. The present study investigates six researchers' perceptions of...
