In order to avoid the single-point-failure problem in centralized Web service publication and search mechanisms, an alliance-based Web service discovery method for unstructured P2P network was proposed in this paper. A service alliance is composed of web services with same functional properties. By using of the alliance-information-list, service requests could be spread rapidly through out the alliance...
Data switch structure is necessary to support data transfers in network on chip (NoC). Most of designs can only support one-direction data transfer, and the potential concurrency is omitted. Concurrent multi-direction data switch structure (CMDSS) that proposed before can offer several concurrent transfers. In this paper, graph theory is used to help designing the structures, and the method is called...
This paper studies influencing factors on the structure of clouds and the availability of satellite remote sensing images on base of that, and puts forward that the cloud area, cloud thickness and cloud fragment are the main factors. Combined with immune coding algorithm, the cloud area can be calculated; with the impact patterns on images by atmospheric scattering, refraction, and so on, a method...
