A self-adaptive improved particle swarm optimization (IPSO) algorithm applied to available transfer capability (ATC) calculation is presented in this paper. Firstly, a new self-adaptive adjustment inertia-weighted strategy factor, which elevates the adaptability of particle swarm optimization (PSO) and accelerates convergence-speed of PSO, is proposed.(More)
The title compound, C18H28O3, was prepared by the reaction of 2,6-di-tert-butylphenol with methyl acrylate under basic conditions using dimethyl sulfoxide as the promoter. The structure of this antioxidant indicates significant strain between the ortho tert-butyl substituents and the phenolic OH group. In spite of the steric crowding of the OH group, it(More)
This paper presents an Improved Bacterial Colony Chemotaxis (IBCC) algorithm based on BCC. In this paper, the optimization of n-dimensional problem is simplified as the optimization of n-1 sub-problems of 2-dimension by presenting the new formulation. As for the searching characteristic of a cell and colony, self-adaptive adjustment error parameter strategy(More)
The fabrication and radio frequency (RF) protection ability of semiconductor junction igniter (SJI) is presented. The SJI consists of two back-to-back PN junctions, with a predesigned size, which is designed to protect against the RF and electrostatic discharge events. The effect of doping density on electromagnetic susceptibility of SJI is studied by two(More)
