Catastrophe mechanism and classification of discontinuity behavior in thermal science (II)

The catastrophe mechanisms of thermal performance characteristics of the firebox gas combustion system were analyzed from the viewpoint of catastrophe theory. The mathematical models of cusp catastrophe were established. The relationship between the thermal performance characteristics and the changing of system control variables was studied. The cusp catastrophe mechanisms of typical performance characteristics, such as kicking and lagging, and those of transition from quenching to igniting were explained. It was illustrated that discontinuity behavior of thermal systems with an “S” motion feature curve and lagging feature may be equivalently classified according to the topology of cusp catastrophe, influenced by two groups of independent control variables.     

Electromagnetic tomography: dyadic Green'' s function method

This study aims at formulating a dyadic Green' s function method for directly solving the forward and inverse problems of the electromagnetic tomography (EMT) with parallel field sensor. First, an integral equation of the electromagnetic problem for the EMT sensor is presented in terms of an equivalent source, which takes the dyadic Green's function G (r, r') as its kernel. Next, starting from a single conducting cylinder filled with homogeneous medium, a convenient way of finding the electric dyadic Green's function of the first kind Gel( r, r) is described based on the method of Ga. Then, an eigenfunction expansion of the Gel( r, r) into vector wave functions M and N is obtained by means of a contour integration. Finally, an expression of the G( r, r' ), the dyadic Green' s function for the EMT sensor with cylindrically layered structure, is deduced from Gel(r, r) by adding reflected wave terms to it.

综合智能系统框架的研究及其实现

当前人工智能(AI)正处在一个转折时期,无论是基于符号推理的专家系统(ES),还是基于网络推理的人工神经网络(ANN)在使用过程中都已暴露出了不可克服的缺点。因此,将ES与ANN结合起来构成混合系统(Hybrid System)已经成为大势所趋,同时考虑到人在智能模拟中的不可替代作用,又应将人的因素与混合系统进行综合集成从而构造综合智能系统(Integrated Intelligent Sysrem)。本文探讨了一个基于人,神经网络,专家系统集成的综合智能系统框架,并给出了一个基于此框架而开发的组合机床流水线智能报价系统的实例,
