A method to pinpoint the rubbing location in a rotor-bearing system is presented. This method is based on the data sampled by acoustic emission (AE) sensors placed at di!erent bearing supports. Usually, the point where rubbing occurs cannot be detected using the method of cross-correlation directly

We would like to propose a method of single evoked potential (EP) extraction free from assumptions and based on a novel approach -the wavelet representation of the signal. Wavelets were introduced by Grossman and Morlet in 1984. The method is based on the multiresolution signal decomposition. Wavele
Images and spectra contain a large amount of data. Therefore the question arises, how this data can be decreased or compressed without losing important detail. The discrete wavelet transform is a tool which can be used to compress data because of its good approximation properties. It is very easy to
