As numerical tools, a hybrid Transmission-Line Matrix (TLM) modeling method and modal approach is applied. The non-homogeneous volumes are discretized upon TLM, while the planar structures are modelled with the mode matching approach. The results prove the benefits of the combined GC and hybrid approach to solve electrically large structures.

Transmission-Line Matrix (TLM) modeling method is applied to homogeneous volumes. The planar structures are modelled with the mode matching approach. The results prove the benefits of the GC and supercomputer environments to solve electrically large structures. A prediction model for computing performances on grid, based on a hybrid approach that combines a historic-based prediction and an application profile-based prediction, has been developped. The predicted values are in good agreement with the measured values.

This paper deals with the electromagnetic modeling of large and complex electrical structures by ... more This paper deals with the electromagnetic modeling of large and complex electrical structures by means of extensive parallel modeling based on grid computing (GC). The numerical modeling is based on a hybrid approach which combines Transmission Line Matrix (TLM) and the mode matching methods. The former is applied to homogeneous volumes while the latter is used to describe planar structures presented within the entire simulation domain. The results prove the benefits of the combined GC and hybrid approach to solve electrically large structures.

The first has money and wants to capitalize on them as possible, and the second wants to enter into possession of a capital base which is to put up a new business or develop an existing. We can say that in this context we are facing a certain demand and a supply of capital. Meeting supply and demand of the said capital shall be carried out in an organized framework, namely the capital market. Investors as owners of capital seeking to invest capital so advantageous that they must choose from several investment on the one that best suits his or her interests. In the choice between several investment options investor must thoroughly know the subject of its investment capital, form of revenue will occur when they occur, what time is immobilized the capital and the risks of its investment capital.
