Compared with conventional power transformer, power electronic transformer (PET) has many merits and an increasing possibility to replace it in the future. In this paper, the unbalanced-load correction capability of two H-bridge based three-phase three-stage modular PET topologies, the separate-phase-connection (SPC) one and the cross-phase-connection (CPC) one, are analyzed and compared. Both of...
QoS value prediction of Web services is an important research issue for service recommendation, selection and composition. Collaborative Filtering (CF) is one of the most widely used methods which employs QoS values contributed by similar users to make predictions. Therefore, historical QoS values contributed by different users can have great impacts on prediction results. However, existing Web service...
Traditional mesh is a popular interconnection architecture for Networks-on-Chip (NoCs). However, with the trend towards larger number of cores in chip multiprocessors, it is unable to stand the fast-growing diameter and average distance in meshes. Recently, concentration and express channels are two countermeasures for that. In this paper, a new scheme called multi-mapping is proposed, which allows...
