Grid-based mesh generation methods have been available for many years and can provide a reliable method for meshing arbitrary geometries with hexahedral elements. The principal use for these methods has mostly been limited to biological-type models where topology that may incorporate sharp edges and curve definitions are not critical. While these applications have been effective, robust generat...

Interest in and requirements for the next generation of information technology for science are expanding. eScience has become a growing subject of discussion covering topics such as grid computing for science as well as knowledgeenhanced scientific data retrieval. The demand for deep integration of scientific data within and between disciplines is also growing, as larger and broader science que...

South Africa’s Government policy embraces the inclusion of distributed energy resources (DER), namely: renewable energy generation, embedded generation (EG) or distributed generation (DG) in the future national generation mix. The renewable energy program incorporates wind power, concentrated solar power (CSP), solar photo-voltaic (PV), landfill, and mini/micro hydro, and envisages a total of 1...

A rapidly increasing share of renewable energy resources (RES) poses enormous challenges with respect to a market and grid integration in Germany. Whereas market related integration is encouraged through additional incentives, grid conformity is realized by means of requirements on voltage and frequency support required for RES and decentralized generation (DG). Nevertheless, grid restrictions ...

Graphical user interfaces (GUIs) have gained primacy among the means of interacting with computing systems, thanks to way they leverage human perceptual and motor capabilities. However, design GUIs has mostly been a manual activity. To GUI, designer must select its visual, spatial, textual, interaction properties such that combination strikes balance relevant factors. While emerging computation...

Grid computing is the key technology of next generation Internet. Today grid research is mostly focus on the communication, security, resource manangement and information management. Charging and accounting is a base activity in a economy society, so that it should become a part of grid computing system in computational economy environment. In this paper, we introduce charging and accounting it...
