In view of inherent insufficiency of traditional fault diagnosis expert system in the aspect of knowledge representation, together with the characteristics of fault tree, hierarchical model and expert system, this paper puts forward a knowledge base maintenance approach based on Object-Frame knowledge representation, in which domain specific knowledge is expressed by combinations of the relevant objects'...
With the rapid advances in communication and networking, especially in grid technique, an increasing number of applications will involve computing systems. Consequently, the system aims at the puzzles in current HLA-based simulation system, and combines with a new grid technique. These simulation applications in turn create an increasing demand for efficient resource management, request handling policies...
Ultrasonic degradation of hydroxyethyl cellulose (HEC) in aqueous solution was investigated. The degradation rate of this polymer was found to follow the Baramboim kinetic equation. Rate constants and the generating rates of radicals produced by ultrasonic irradiation were calculated, and the results showed their dependence on polymer concentration. Copolymers of methyl methacrylate/HEC and acrylic...
