In the paper, based on the existing literature research foundation an analog circuit catastrophic fault location approach by using feedforward networks with back ? propagation learning is realized. by this approach, the simulation require ments before test are reduced because fewer training samples are needed, and the fault location process is fast. this method is very efficient in location of single hard fault wit component tolerances. the measureme nt space feature and the general characterization concept of single and double soft fault in linear circuits are presented. according to this concept, a linear circuits soft fault location approach using subhidden layer bpnn is established with element tolerance, and it is shown that this approach is successful in fault location. a double fault feature extraction.,

Abstract : the computational and compositional features are very important while constructing parallel software for the workstation clusters. however, lack of suitable supporting environment for parallel software development makes most existing distributed parallel software systems very weak in these two aspects, especially in the compositional feature. in this paper, a distributed object based framework for parallel computation is proposed. the goal of the framework is to achieve high efficiency for parallel computing, to construct a mechanism to encapsulate and reuse parallel programs, and to guarantee load balancing and fault tolerance. the framework is a four - layer model that includes an object - group layer and a mobile object layer. the experimental results verify the efficiency of the scheme
