Abstract In order to monitor the resistance state of urban cables online and obtain cable line insulation accurately, an monitoring method based on grey-Markov error back-stepping model is proposed, system designed. The calculated by combining fuzzy membership function evidence synthesis algorithm, grey theory applied predict data calculate relative between predicted value original data. Based ...

Web server workload forecasting is one of the essential considerations in web server management and network upgrading. Due to variability of server workload distribution originated from unpredictable users’ surfing behavior, the measurement of Web server performance metrics is characterized and modeled in fuzzy manner. A fuzzy inference system is formed using four Web server performance metrics...

PURPOSE: The purpose of present paper is to compute the fuzzy reliability of the stainless steel utensil manufacturing unit for the constant failure and repair rates. The effect of variations of fuzzy reliability with time and system coverage factor for a set of failure and repair rates is also studied. METHODOLOGY/APPROACHThe mathematical model of Stainless Steel Utensil Manufacturing Unit has...

Station autonomous computer system is the core of centralized traffic control (CTC) system. The working mode dual hot standby, and its reliability very important. Due to dynamic fuzzy issue with analysis station system, a method formulated based on fault tree (DFT) Markov model. First, structure principle standby double 2-vote-2 are analyzed, two systems DFT formulated. Then, failure rates dete...

An unconstrained Farsi handwritten word recognition system based on fuzzy vector quantization (FVQ) and hidden Markov model (HMM) for reading city names in postal addresses is presented. Preprocessing techniques including binarization, noise removal, slope correction and baseline estimation are described. Each word image is represented by its contour information. The histogram of chain code slo...
