An improved cloud resource revenue optimization models are proposed, which include the benefits of service providers and users negotiate SLA agreement. And the models define the constraint mechanism for describing service quality problems such as service response time and customer satisfaction. We design the comprehensive response indicator and use this indicator to quantify the rationality of the...
Computing top-k results matching XML queries is gaining importance due to the increasing of large XML repositories. In this paper, we propose a novel two-layer-based index construction and associated algorithms for efficiently computing top-k results for SLCA-based XML keyword search. We have conducted expensive experiments and the results show great advantage on efficiency compared with existing...
The way of on-board digital signal processing based on FPGA is studied. It contains requirement analysis of the on-board processing functional specifications, an on-board real-time digital signal processing system is designed with radiation tolerant FPGA. The design takes full advantage of the massively parallel architecture of the FPGA logic slices to achieve real-time processing at a high data rate,...
