This paper presented the mathematical models of load three-phase equilibrium optimal allocation in low-voltage power network, studied the commonly used graphical modeling method based on the painted electric writing diagram of low-voltage power network. Using Visio 2003 we developed a practical auxiliary system of calculating the line loss in low-voltage network and load optimal allocation. It is...
Mobile Internet access becomes a major research focus with the increase of mobile phones. This paper introduced and summarized a variety of wireless technologies supporting mobile Internet access. Firstly, the current progressing wireless access technologies were valued on their strengths and weaknesses. Then the newest mobility support researches and progresses over IP layer, such as MIP, NEMO, SIP...
The fundamental theory of topological optimization was enunciated in this paper, and topological optimization method provided by ANSYS software was used to optimize the structure of rear platen of injection molding machine. The optimal structure was found out and it provides the theoretical base for further improving the platenpsilas structure.
Nitrogen atomizing process is with nonlinearities, large time delay, strong coupling and severe uncertainty, and thus it is difficult to obtain the deterministic model by mechanistic method. In this paper, the process model based on RBF neural networks is presented to estimate the particle size distribution of aluminum powder by means of measurements of melted aluminum level and temperature, atomizing...
