Based on the local approximate form of the beam shape coefficients and the coordinate rotary theory of the vector sphere wave functions, the expansion form of the field of the Gaussian beam in terms of the vector sphere wave functions at arbitrary coordinate system is obtained. The scattering of arbitrary direction Gaussian Beam from bisphere is investigated according to generation Mie theory (GMM)...
This paper investigated the catalytic ozonation of aqueous nitrobenzene (NB) in the presence of nano-TiO2/zeolite. The removal efficiency of NB was increased from ozone alone at 12.57% to in the present of catalyst at 33.76%, significantly. The optimum calcination temperature of nano-TiO2/zeolite was found out at 600degC. Catalytic ozonation of nitrobenzene was first order reaction with respect to...
Similarity calculation is the key to solve the question that concept matching in semantic and affects the quality of service composition, and so have strong effect on satisfaction of users. In view of inadequateness, of the current concept similarity calculation that all kinds of factors are not considered comprehensively, the paper proposed the method of internal and cross ontology concept of similarity...
With the continuous deepening of the network technology and application , there is strict requirements inequality of service (QoS) to the grid, how to reasonable allocation resources so that the maximum utilization of the resources becomes a press for solution based on users in meeting the requirements of QoS. In this paper to the dynamic,distributing and isomerism of grid resources a QoS-based dynamic...
Action grammar is a grammar with action symbols appearing in the right part of production rules, which can be used to implement semantic analyzer automatically. An action symbol represents the name of a semantic routine. Implementation of action grammar relies on specific parsing methods, such as LL(K), recursive-descent or LR, and so on. However, these parsing methods have their own restrictions...
