Abstract Based on overset grid method, the problems about flow past circular cylinder were numerically studied, which include around a single at Reynolds number Re=100 and Re=200, two tandem cylinders Re=200 dimensionless distance g * =4, lateral oscillating Re=200. Overset method is effective in dealing with of over multi-body moving boundaries. This couple overlapping regions an arbitrary man...

A grid resource broker seeks to assign the appropriate jobs to the appropriate resources as part of resource management in the multi-grid environment. Multi instances of the broker system provides multiple instances of brokers to simultaneously process jobs between multiple resources in a hierarchical cluster grid environment. In this study, the multi-instance broker is developed using grid res...

E-finance is rapidly transforming and evolving toward more dynamic, flexible and automated solutions. This paper describes a conceptual model with dynamic multi-level workflows corresponding to a multi-layer Grid architecture, for multi-aspect analysis in building an e-finance portal on the Wisdom Web. The application and research demonstrate that mining-grid centric three-layer Grid architectu...

The sliding window approach is the most widely used technique to detect an object from an image. In the past few years, classifiers have been improved in many ways to increase the scanning speed. Apart from the classifier design (such as cascade), the scanning speed also depends on number of different factors (such as grid spacing, and scale at which the image is searched). When the scanning gr...

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...

This paper presents a new multi-function conversion technique for vehicle-to-grid (V2G) applications. The proposed bi-directional charger can achieve three functions, including EV battery charging, grid-connection and reactive compensation, which are keys for energy management of the grid. With the proposed multi-function technology, the bi-directional charger will benefit both the grid and ele...

In this paper we describe an algorithm for fault-tolerant sensor mapping for robotic vision. Basically, we use a certainty grid algorithm to map distance measurements into a two-dimensional grid. The well-known certainty grid algorithm can tolerate occasional transient sensor errors and crash failures, but will fail when a sensor provides permanently faulty measurements. Therefore we extended t...
