This paper provides a review of the Teager–Kaiser (TK) energy operator and its extensions
for signals and images processing. This class of operators possesses simplicity and good …

Planetary gearbox fault diagnosis under nonstationary conditions is important for many
engineering applications in general and for wind turbines in particular because of their time …

This paper proposes a novel methodology to precisely estimate the generation units' inertia
constant by using the wide-area monitoring systems (WAMS) information of bulk power …

Rolling element bearings are among the most important components of rotating machinery,
being the interface between the stationary and the rotating parts. Bearing failures might …

Motor current signature analysis (MCSA) has been widely used for fault diagnosis of
induction motors (IMs) because of its non-invasiveness and comparatively low cost …

Muscle onset detection plays a key role in applications ranging from clinical to assistive
technology. The Teager-Kaiser energy operator (TKEO) is an acknowledged tool used in …

It is hypothesised that a key characteristic of ECG signal is its non-linear dynamic behaviour
and that the non-linear component changes more significantly between normal and …

High resolution (HR) multi-electrode mapping is increasingly being used to evaluate
gastrointestinal slow wave behaviors. To create the HR activation time (AT) maps from …

Objective. A significant challenge in surface electromyography (EMG) is the accurate
identification of onset and offset of muscle activation while maintaining high real-time …

Time-frequency distributions that evaluate the signal's energy content both in the time and
frequency domains are indispensable signal processing tools, especially, for nonstationary …
