Abstract: In this work, the reverse dispersion entropy (RDE) is used to process the squared envelope (SE) signal in order to detect nonstationarites. Based on the idea of spectral kurtosis (SK) and kurtogram, the squared envelope ...

Abstract: The nonorthogonal basis generalized Fourier transform is used as orders extraction technique during machinery speedup and slowdown tests due to nonstationary nature of vibration signals in these tests. The kernels of this ...
