This paper first presents a novel model for QoS-aware web services composition based on workflow patterns, and an executing path tree with probability. Then a discrete PSO algorithm is proposed to fit our model, which also requires some other preliminary algorithms, such as the generation of all reachable paths and executing path tree. The experiments show the performance of that algorithm and its...
The main purpose of this research is to perform a magnetic analysis on the magnetic equipment of permanent magnet retarder (PMR) and optimize the structure of magnetic equipment with the commercial FEM software ANSYS and its design optimization module. The FEM model is built as an axisymmetric model according to the characteristics of the structure of magnetic equipment. Using this model, the magnetic...
