Many real-world systems such as multi-processor computing and power transmission systems have load sharing attribute where the whole system workload is distributed to different system elements. In these systems, when one element fails, other remaining elements would take over the workload which will change their failure behavior and cause a dynamic dependence of failure, thus a reliability evaluation...
This paper presents a new unidirectional cascaded bridgeless multilevel rectifier (CBR) well suited for serving as the rectifier stage of a transformerless cascaded multilevel converter. Compared to a traditional cascaded H-bridge rectifier, the proposed CBR utilizes fewer fully controlled switching devices by replacing the fully controlled H-bridge modules with bridgeless PFC modules, thus simplifying...
Based on CST, models of the heavy current facilities in the subway system have been built and the simulation has been completed to acquire the radiation of EMI. By comparing the results of the simulation with the corresponding results of the actual measurement, the models are modified until the simulation of the models could mainly reflect the situation of Electromagnetic field around the heavy current...
Considering the access authentication for mobile terminals in the 3G-WLAN heterogeneous networks, a new WAPI secure access authentication scheme based on the identity-based cryptograph was designed. And its security attributes was formally proofed with Protocol Composition Logic. By the security proof and comprehensive analysis, it is showed that the proposed scheme not only has session authentication...
