In this paper, genetic algorithm-based approach for transient analysis of single transmission line connected to arrester is proposed. In this approach, the lightning channel striking the overhead line is first represented by a current source and this source is truncated by a finite set of frequency harmonies in time domain. Norton equivalent circuit viewed across arrester is then computed by me...

Let be the percentage of zeros among the quantized transform coeÆcients. We discover that, in any typical video coding systems, there is always a strictly linear relationship between and the actual coding bit rate R. This linearity leads to a novel and uni ed source model for di erent types of source data and di erent coding systems, such as H.263 [1], MPEG-2 [2], and MPEG-4 [3]. The proposed l...

This paper presents a method to control both the dc boost and the ac output voltage of Z-source inverter using neural network controllers. The capacitor voltage of Z-source network has been controlled linearly in order to improve the transient response of the dc boost control of the Z-source inverter. The peak value of the line to line ac output voltage is used to control and keep the ac output...
