The objective of the study is to analyse the actual availability of water resources and its impact on human health deterioration. The following aspects were studied: (a) human activities and environmental deterioration; (b) statistics on the availability and demand of water resources; (c) urban and industry wastes as sources of water resources contamination; and (d) deleterious effect of contam...

one of the specific aspects of our time is the existence of world trade organization as an important international center. this organization regulates the commercial laws among the countries, and tries to provide a suitable environment for trade by eliminating the subsidies using protection policies and making a better condition for competition. in order to achieve this objective, the economic ...

Computational Grid has become widespread and lead the way to high-performance computation using widely dispersed resources. The computational GRID architecture is very dynamic by nature with its distributed resources over many organizations, its heterogeneous resources, and pervasive availability with variety of tools. For the best performance of GRID computing, it is inevitable to find computa...

Recent trends in the business world has forced companies to expand their activities into new regions where they can find qualified manpower, lower production costs, high availability of raw materials giving rise to wider and more complex supply chains but also bringing in new opportunities to leverage their competitive advantages. These changes require the implementation of new organizational m...

The Open Source Cluster Application Resources (OSCAR) project is the founding working group of the Open Cluster Group (OCG). The OCG is an informal group of people dedicated to making cluster computing practical for high performance computing and more recently, clustering in general (high availability, diskless). OSCAR is a package that makes it easy to build clusters for high performance compu...

data grid is an infrastructure that controls huge amount of data files, and provides intensive computational resources across geographically distributed collaboration. the heterogeneity and geographic dispersion of grid resources and applications place some complex problems such as job scheduling. most existing scheduling algorithms in grids only focus on one kind of grid jobs which can be data...
