Abstract:A
novel approach for identification of shaft center orbits is proposed,
which bases on wavelet modulus maxima. In
this approach, continuous wavelet transforrn is put on @-S diagram of
shaft center orbits, then, maxima Iines are extracted and Lipschlt
Key words: Wavelet
transform Modulus maxima Lipschitz exponent Shaft center orbit
