Web23 de nov. de 2011 · It cannot be assumed that respondents who are clustered are statistically independent. For example, it is very unlikely that students in a science laboratory are statistically independent, especially with regard to the collection of data related to laboratory experiences.
WebSpectral kurtosis is one of the techniques for vibration analysis. A considerable attention has been paid for the fault diagnosis using spectral kurtosis. In this paper, an estimator of spectral kurtosis based on the short time Fourier transform is summarized, an inner-outer bearing fault is simulated. The bearing
