STUDY ON REAL1STIC TECHNOLOGY OF CONDITION MONITORING AND FAULT DIAGNOSTIC SYSTEM FOR SHIPPING POWER DEVICES

Condition monitoring and fault diagnosis is currently a very important problem in large-scale complicate power devices. Both scheme and realistic technology for monitoring system hardware and software have been present to solve the problem in this paper. The fault diagnostic model based on artificial neural network and state identification method based on fuzzy analysis are studied.     

Criteria and approximate methods for path-constrained moving-target search problems

A search is conducted for a target moving in discrete time among a finite number of cells according to a known Markov process. The searcher must choose one cell in which to search in each time period. The set of cells available for search depends upon the cell chosen in the last time period. The problem is to find a search path, i.e., a sequence of search cells, that either maximizes the probability of detection or minimizes the mean number of time periods required for detection. The search problem is modelled as a partially observable Markov decision process and several approximate solutions procedures are proposed. © 1995 John Wiley & Sons, Inc.
