Current perspective of the renewable energy development in Malaysia
(Elsevier Ltd., 2011-02)
It is estimated that oil reserves will not last very much longer; thus, a switch to alternative energy solutions is crucial. The Malaysian government has already prepared to face the situation decades before. Many policies ...
Transmission loss allocation in deregulated power system using the hybrid genetic algorithm-support vector machine technique
(Cyber Journals, 2011-01)
This paper proposes a new method to trace the
transmission loss in deregulated power system by incorporating
the Genetic Algorithm (GA) and Least Squares Support Vector
Machine (LS-SVM). The idea is to use GA to find ...
Rubber tire dust-rice husk pyramidal microwave absorber
(EMW Publishing, 2011)
Rubber tire dust-rice husk is an innovation in improving the design of pyramidal microwave absorbers to be used in radio frequency (RF) anechoic chambers. An RF anechoic chamber is a shielded room covered with absorbers ...
