This paper presents an optimization methodology for placement of switches in medium-voltage loop distribution networks. The primary objective is to minimize the total cost with consideration of achieving high distribution reliability levels. In this paper, four possible states are considered and discussed, and the improved genetic algorithm is adopted to determine the optimal number and locations...
Transplantation of adult marrow stromal cells (MSCs) has been developed as a new method of treating severe ischemia diseases by therapeutic angiogenesis. Erythropoietin (EPO) is capable of inducing angiogenesis and inhibiting MSCs apoptosis. The effect of EPO on the therapeutic potency of MSCs transplantation in a rat model of limb ischemia was investigated in the current study. The results indicate...
Research was made on the design scheme and basic algorithm of a kind of voltage-feedback type digital stabilized voltage switching mode power supply combining internal resources of single-chip microcomputer with control technique. Take 110V switching mode power supply by electric locomotive as an example, it adopted advanced sensor in sampling data, applied PID control algorithm to adjust voltage...
