This study presents a novel approach to discover features that distinguish the vibration signals of a normal motor from those of an abnormal one. These features are obtained from the difference of multiscale entropy of a signal before and after the signal is denoised using wavelet transform , or just use multiscale entropy after the signal is denoised using wavelet transform. Experimental results show the classifier can effectively distinguish between normal and abnormal motors. Yu-Chih Liu Jun-Lin Lin 劉俞志 林志麟 2010 學位論文 ; thesis 32 zh-TW
