In this paper, a new topological design of permanent magnet (PM) motor with Halbach magnet is introduced and investigated. To better evaluate the performance of different types of motors, a novel approach for the design optimization based on an improved Tabu search algorithm and finite element method (FEM) is proposed. The improvements include a normalized step vector for different search spaces,...
The finite element-boundary integral-multilevel fast multipole algorithm (FE-BI-MLFMA) has shown to be very general and powerful for 3D scattering. This paper reports our major progress of FE-BI-MLFMA made over the past years. First, we report the study on different approaches of choosing surface in FE-BI-MLFMA. Second, we present the comparison of different algorithms of FE-BI-MLFMA. Third, we compare...
Association analysis arises in many important applications such as bioinformatics and business intelligence. Given a large collection of measurements over a set of samples, association analysis aims to find dependencies of target variables to subsets of measurements. Most previous algorithms adopt a two-stage approach; they first group samples based on the similarity in the subset of measurements,...
