Detection of cracked-shell eggs using acoustic signal and fuzzy recognition;

Characteristic extraction of acoustic signals emitted from resistance spot welding process based on independent component analysis

When the running situation of a rotating machine becomes abnormal or a part of it does not work well,it usually generates a periodic vibration signal or a periodic acoustic signal,which generally are periodic impulse signals with relatively strong noise.
