Vibration signals of faulty rolling element bearings usually exhibit non-linear and non-
stationary characteristics caused by the complex working environment. It is difficult to …

Due to its practical importance, the diagnosis of rolling element bearing has attracted
constant interest in the scientific community. At the incipient stage of a failure, the measured …
