... of the gear unit. 5. Conclusion By means of adaptive wavelet transform it is possible both to define changes and to establish the presence of a damage or fault, at the level of an individual tooth. ... Due to this, it is possible to, by optimising the two parameters for a daughter wavelet, build an adaptive wavelet filter. The selection of the mother wavelet that adapt...

... <h≤ 1/a. The main goal of symbolic dynamics is to determine all of the possible motions of a system under study. In practice, all of the allowed short periodic sequences up to a certain period are ... up to a certain number with little computer time. Examples for consecutive periods of orbits are raised for the Lorenz maps. With a little variation, the theorems and algo...
