We have witnessed successes of production grids and various grid applications in last decade. Motivated by previous and current grid initiatives and raising science community demands for computing resources, project CRO-GRID was initiated. CRO-GRID is a national multi-project whose goals are introduction of grid and cluster technologies to science community and industry and development of distr...

Micro-grid control is the key technology in the process of accessing micro-grid into regular grid. This paper summarizes several ways on coordination control in micro-grid and introduces some domestic researches on micro-grid control strategies. It is written on the basis of the achievements on micro-grid control in some developed countries and current situations on domestic micro-grid control....

We present a detailed description of the implementation of a library of Grid tag libraries and Grid beans for Grid Web portal development. Grid tags provide Java Server Faces (JSF) custom components for Grid services. They enable the definition of attributes to the Grid service parameters in a dynamic way embedded into JSF view pages. In addition, Grid beans provide client proxies to the Grid s...

In the framework of Open Grid Service Architecture, this paper presents the design of LinuxCluster-Based Grid Services. Using Cluster System Management , General Parallel File System and openMosix, LinuxCluster-Based Grid Services have good performance. Then the paper introduces the Component model to Grid service, and builds Grid Component Service. Grid Component technology will greatly improv...

Kriging is an advanced geostatistical procedure that generates an estimated surface or 3D model from a scattered set of points. This method can be used for estimating resources using a grid of sampled boreholes. However, conventional ordinary kriging (OK) is unable to take locally varying anisotropy (LVA) into account. A numerical approach has been presented that generates an LVA field by calcu...

The objectives of this study were (a) to examine the writing performance of L2 learners on the level-specific tasks based on Common European Framework of Reference (CEFR) and (b) to study the likely difference between students' self-assessed level of writing and those reported by raters. The study was conducted with 138 Iranian students at BA and MA levels in Alborz Institute of Higher Educatio...
