changes in the physicochemical conditions of process unit, even under control, may lead to what are generically referred to as faults. the cognition of causes is very important, because the system can be diagnosed and fault tolerated. in this article, we discuss and propose an artificial neural network that can detect the incipient and gradual faults either individually or mutually. the main fe...

The breakdown of the dry-type reactor induced by being exposed to moisture needs be further explored. For this purpose, as common insulating films in reactor, PET and PI were targeted investigate effects atmospheric hydrothermal aging on microstructure, thermal stability, mechanical properties films. As result aging, moisture-based degradation obviously occurred surface both films, even at a lo...

The highest quality and timely diagnostics of windings’ state various types electrical machines including asynchronous motors’ windings is an impoitant task. Among the existing diagnostic methods currently most promising are those ones based on for analyzing resonance processes occurring in machines. aim article was to assess possibility use resonant qualitative their using motors example, buil...

Two-day-old male cowpea weevils, Callosobruchus maculatus, fly upwind to a point source of female sex pheromone at three wind speeds. All beetles initiating flight along the pheromone plume make contact with the pheromone source. Analysis of digitized flight tracks indicates that C. maculatus males respond similarly to moths tested at several wind speeds. Beetles’ mean net upwind speeds and spe...

Up to 38% of asynchronous motor (AM) failures are caused by damage the stator insulation. Despite wide variety methods, reliability determining inter-turn short circuits windings under operating voltage still remains at a low level. The existing methods for diagnostics failure interturn circuit winding have been examined. New diagnostic individual parameters developed in course previous study d...

the investigation of this paper focuses on eastern part of shahroud fault system in middle-east alborz. this fault system is an important part in the seismotectonic map of the area. we used two local temporary dense seismological networks data installed around the fault system for several months during 2007 and 2008 and simultaneously micro-earthquakes data recorded by the permanent seismologic...

quantum dot cellular automata (qca) is one of the important nano-level technologies for implementation of both combinational and sequential systems. qca have the potential to achieve low power dissipation and operate high speed at thz frequencies. however large probability of occurrence fabrication defects in qca, is a fundamental challenge to use this emerging technology. because of these vari...

This article aims to provide a technique for identifying and categorizing interturn insulation problems in variable-speed motor drives by combining Salp Swarm Optimization (SSO) with Recurrent Neural Network (RNN). The goal of the proposed is detect classify Asynchronous Motor faults at their early stages, under both normal abnormal operating conditions. uses recurrent neural network two phases...
