“…We pay special attention to intelligent techniques fault diagnosis: self-organising neural networks [4], dynamic wavelet neural networks [5], recurrent neural network [6,7], recurrent neural networks and neural-fuzzy inference systems [8], neural-fuzzy approach [9][10][11][12][13][14], hybrid intelligent methods [1], applied to estimation the different features of process equipment: remaining useful life [3], mean-residual-life [9], onset of a failure or predicting the time of ultimate failure [15].…”
