Application of soft computing techniques for multi source deregulated power system

In this paper, an interconnected power system is proposed for Automatic Generation Control (AGC) in restructured power environment. The customized AGC scheme is projected in deregulated environment for multi-source combination of hydro, reheat thermal and gas generating units in entire area. Proportional integral derivative controller is offered for AGC scheme and the gains are optimised through soft computing...

Computational calculation of the electronic and magnetic properties of 1x1-MN/GaN (M = V, Cr and Mn) multilayers

We employed density functional theory (DFT) in order to study the electronic and magnetic properties of 1x1-MN/GaN (M = V, Cr, and Mn) multilayers, in the wurtzite-type hexagonal structure. The calculations were carried out using a method based on full-potential linearized augmented plane waves (FP-LAPW), employed exactly as implemented in Wien2k code. For the description of the electron-electron interaction,...

UV Absorption and dynamic mechanical analysis of polyethylene films

Photooxidative processes that lead to chain scission and chain linking in polymers play an important role in polymer degradation. These processes are induced by both ultraviolet (UV) and visible light absorption. The capability of these radiations to be absorbed depends on the existence of chromophores in the polymeric material. Assessment of photodegradation data obtained from a polymer material processed in a...
