We presents a parallel algorithm for extrapolation methods on distributed memory multiprocessors combining diierent levels of par-allelism. A detailed analysis that uses appropriate primitives for communication shows that a sophisticated load balancing scheme is required to achieve a good speedup. We characterize an optimal load balancing based on Lagrange multipliers and investigate several si...

In order to conduct a data-driven load forecasting modeling and its application in optimal control of air-conditioning system, this study used hotel’s central air conditioning system as the research object. Based on data hotel energy management load-forecasting model based support vector regression (SVR) was established by MATLAB. working principle chiller, chilled water pump, cooling tower, co...

flexible ac transmission systems (facts) controllers with its ability to directly control the power flow can offer great opportunities in modern power system, allowing better and safer operation of transmission network. in this paper, in order to find type, size and location of facts devices in a power system a dedicated improved particle swarm optimization (dipso) algorithm is developed for de...

In this paper, we present a mathematical model for determining the optimal radius of the iron pole shape in spoke-type permanent-magnet (PM) machines (STPMM) in order to minimize the pulsating torque components. The proposed method is based on the formal resolution of the Laplace’s and Poisson’s equations in a Cartesian pseudo-coordinate system with respect to the relative permeability effect o...
