To indicate exactly the reliability of large-scale high-speed broadband communication network with domain partition and interconnection, a novel reliability index weighed by normalized capacity is defined, which organically combines connection performance with capacity. The correctness and rationality of the index are demonstrated on the aspects of objective factor of network and subjective factor...
Information retrieval has been the important problem of research in unstructured P2P systems. In order to improve the efficiency of the data retrieval, this paper proposed an algorithm for intelligent search based on skyline query technology. Combining the similarity of messages and the hit rate of nodes, a best set of neighbour nodes which was sent messages to was obtained by skyline query technology...
This paper addresses the issue of performance evaluation of parallel manipulators. In the analysis and design process of parallel manipulators, the performance evaluation is the most important problem. The developed index will be fundamentally involved in the process, especially in that of optimum design. Although parallel manipulators have been extensively studied for more than twenty years, unfortunately,...
Monitoring seasonal changes in vegetation activity over wide areas is essential for many applications, Satellite remote sensing offers a systematic and objective means for detecting and monitoring ecological environment.A large amount of satellite remote sensing data at different spatial, spectral and temporal resolutions was proved to estimate Land cove change.One of the most widely used approaches...
