This paper presents an efficient variant of particle swarm optimization (PSO) algorithm named Time Varying Acceleration Coefficients (PSO-TVAC) to solve the optimal coordination of directional overcurrent relays (DOCRs) in a practical power system, considering the optimum pickup current (Ip) as discrete parameter and time dial setting (TDS) as continuous parameter, in order to obtain minimum operating...
The paper deals with the problem of thermal fatigue cycles phenomenon, which affects the performance of flexible pavement. The purpose of the paper is to extent the knowledge on the rheology of polymer modified bitumen which was affected by cycles of thermal fatigue. The aim of this research is to determine the rheological components and their evolutions under thermal fatigue with freezing - thawing...
