In the course of running an artificial intelligent system many redundant rules are often produced. To refine the knowledge base, viz. to remove the redundant ru
In order to control the size and shape of Ag nanoparticles obtained by using poly(amidoamine) (PAMAM) dendrimer as template, the complexation between Ag+ ions a
Euler Number is one of the most important characteristics in topology. In two- dimension digital images, the Euler characteristic is locally computable. The for
The abnormal growth of Ag3Sn intermetallic compounds in eutectic Sn-3.5% Ag solder was investigated through high-temperature aging treatment. Microstructural ev
The periodic window is researched by means of the symbolic dynamics and formal language. Firstly, the proper sampling period is taken and the orbital points of
In the present work, the structure and spectra of PuH and PuH2 are defined by B3LYP/SDD method, from which the analytic potential energy function of PuH2 is der
The simplest normal form of resonant double Hopf bifurcation was studied based on Lie operator.The coefficients of the simplest normal forms of resonant double
In order to evaluate cycling characters of zeotropic refrigerants in air-conditioning operation, and to reveal distribution rules of temperature difference betw
Concept of cluster banding heat source model is put forward for the problem of overmany increment steps in the process of numerical simulation of large welding
