This paper firstly introduced the basic idea of task requirement driven sensor management (TRDSM) and analyzed the task requirement of target tracking. Then, a new approach is proposed to deal with the multi-sensor management problem. The new method uses centralized management model to control sensors and the method comprehensively considers target priority and sensor usage cost. Then, sensors resource...
The Web-services stack of standards is designed to support the reuse and interoperation of software components on the Web. Semantic Web services envision the automated discovery and selection of Web services. The discovery and selection process finds matches between requirements and advertisements according to their semantic description. There are already some approaches available for matching of...
With the number of registered Web services growing, Identifying desired Web service is crucial for Web users. Current keyword based service search are inefficient in two main aspects: poor scalability and lack of semantics. Firstly ,the users are overwhelmed by the huge number of irrelevant services returned. Secondly, the intentions of users and the semantics in Web services are ignored. We propose...
The bounds on the rate of uniform convergence of learning processes play an important role in the Statistical Learning Theory. They provide theoretical bases for the application of support vector machine and reflect the generalization ability of the learning machines. This paper mainly deals with the bounds on the rate of uniform convergence of learning processes when samples are corrupted by equality-expect...
Callus culture of Elaeagnus angustifolia was established with the objective to produce proanthocyanidins. The effects of different conditions on the callus growth and the production of proanthocyanidins were researched. The leaf tissue part of Elaeagnus angustifolia was optimum explant of callus induction. The best callus growth and the highest proanthocyanidins production was obtained under the culture...
In this paper, we took Elaeagnus angustifolia as material. The paper studied characteristics of seasonal and spatial variations of proanthocyanidins content. There was an apparent difference in proanthocyanidins content of the leave from May to October, the maximim content of proanthocyanidins in October was 34.36 mgldrg-1 DW, while proanthocyanidins content in July was only 17.16 mgldrg-1 DW. Content...
