While most part of the complex network models are described in function of some growth mechanism, the optimization of a goal or certain characteristics can be desirable for some problems. This paper investigates structural optimization of networks in the highlevel classification context, where the classification produced by a traditional classifier is combined with the classification provided by complex...
Establish the geometric model of the pump body using the three dimensional modeling software based on the drawing pump parts. After a reasonable simplification, analyze and calculate the force of the pump body applying the traditional theory. Take the results as the boundary conditions for the software analysis. Introduce the model into the ANSYS software and calculate the stress and strain. Such...
1000 MW synchronous generator is a large-capacity generator. Three-phase short circuit of synchronous generator is a serious fault in the electric power system, which influences badly on the noumenon of electric machine and correlative electric equipment, which likely causes a great economic loss. It is important to study it. By making use of Simulink in this paper, under the d-q coordinate system...
The strategy of sustainable development is paid more attention by the people in the world. It is urgently to solve such problems by an appropriate method. This article applies ecological footprint to account and analyze the sustainable development of China's Heilongjiang province from 1995 to 2006. The following results were obtained. The arable land contributed most to the ecological footprint among...
The existing modeling methods for Web service composition are not suitable for modeling Web service composition on the business layer. A novel concept model, called DWSCCM, for Web service composition on the business layer are represented in this paper. The initial experiments based on DWSCCM model show that this model is feasible and efficient.
