Service-based systems (SBSs) are distributed systems which have many advantages, including rapid composition of services for distributed applications. In these systems, various capabilities are provided by service providers as services interconnected by networks. It is important for users of SBSs to have confidence in the trustworthiness of service providers. Existing approaches to trust estimation...
The chaos characteristic of vacuum circuit breaker (VCB) under different interruption conditions in synthetic circuit experiment is researched. Using four parameter and two parameter method, comparing the influence of the metal vapor arc model, the variations of voltage and current for different VCBs are obtained. And the chaos in synthetic circuit experiment for the demonstrated VCBs based on the...
A floorplanning algorithm for novel carbon nanotube based three-dimensional integrated circuits is proposed. It is based on ant colony algorithm. The proposed algorithm can optimize the area and area-delay for the single device layer in the three-dimensional integrated circuits, and then optimize the whole 3D IC's area and delay. After the optimization, the performance can improve about 15%.
Based on the analysis of MC-CDMA signal transmitting model and VHF aeronautical channel model, the performance of MC-CDMA system in VHF aeronautical channel is studied and simulated. VHF aeronautical communication band is congested and with serious multi-path fading and channel delay. Combining and benefiting from OFDM and CDMA technology, MC-CDMA can eliminate the interference caused by multi-path...
