A new model for computers and networks is developed and studied. The model has the two-folded form: a grid array, which gives a direct representation for different kinds of computers and networks and its theoretical counterpart, a grid automaton. Grid arrays are aimed at computer/network design, description, verification, adaptation, maintenance, and reusability. Grid automata are aimed at the ...

Grid computing enables the virtualization of distributed computing and data resources such as processing, network bandwidth and storage capacity to create a single system image. The complexity of resource management in Grid significantly increases as the grid computing grows. To solve the problem we propose grid policy administrator with MDP-based resource management scheme. The grid policy adm...

A research work without considering the power constraint cannot be conceded a fine contribution towards Mobile Ad Hoc Networks (MANET). As MANET comes into action for some special purpose, but its fugacity sometimes result degrades in network performance. Although the many prominent features of MANET like mobility, dynamic change in topology, multi radio relaying, quickly lay down the network w...

a critical protection requirement for grid connected distributed generators (dg) is anti-islanding protection. in this paper, a new islanding detection method for any possible network loading is proposed based on utilizing and combining various system parameter indices. in order to secure the detection of islanding, eight intentional disturbances are imposed to the system under study in which t...

Internet technology is too much popular now a day and due to the availability of high performance computer and network technology at low cost change the view of using computer and internet. Grid computing is conceptually not like electric grids. In electric grid we can just link to the outlets of an infrastructure and we don’t need to know from where and how we are getting electricity. Grid com...

Grid middleware provides the fundamental framework for the provision of Grid services. However, Grid middleware is complex software that consists of several modules. The modules for a specific grid middleware exhibit in many cases complementary features and are produced by different software providers. Thus, in order to provide a complete grid solution for business customers, it is necessary to...

In the near future the use of distributed generation systems will play a big role in the production ofelectrical energy. One of the most common types of DG technologies , fuel cells , which can be connectedto the national grid by power electronic converters or work alone Studies the dynamic behavior andstability of the power grid is of crucial importance. These studies need to know the exact mo...

Observations of the Caspian Sea during August-September 1995 are used to develop a three-dimensional numerical model to be used in calculating temperature and current. The model has variable grid resolution and horizontal smoothing that filters out small scale vertical motion. Data from the meteorological buoy network on the Caspian Sea are combined with routine observations at first-order syno...
