Fast computation of the kurtogram for the detection of transient faults

J Antoni - Mechanical systems and signal processing, 2007 - Elsevier
The kurtogram is a fourth-order spectral analysis tool recently introduced for detecting and
characterising non-stationarities in a signal. The paradigm relies on the assertion that each …

The spectral kurtosis: application to the vibratory surveillance and diagnostics of rotating machines

J Antoni, RB Randall - Mechanical systems and signal processing, 2006 - Elsevier
In the previous paper, the authors have demonstrated the high potential of the spectral
kurtosis (SK) to detect and characterise non-stationary signals. The present paper brings …

The spectral kurtosis: a useful tool for characterising non-stationary signals

J Antoni - Mechanical systems and signal processing, 2006 - Elsevier
The spectral kurtosis (SK) is a statistical tool which can indicate the presence of series of
transients and their locations in the frequency domain. As such, it helpfully supplements the …

The relationship between spectral correlation and envelope analysis in the diagnostics of bearing faults and other cyclostationary machine signals

RB Randall, J Antoni, S Chobsaard - Mechanical systems and signal …, 2001 - Elsevier
In recent years there has been an increasing interest in applying cyclostationary analysis to
the diagnostics of machine vibration signals. This is because some machine signals, while …

The infogram: Entropic evidence of the signature of repetitive transients

J Antoni - Mechanical Systems and Signal Processing, 2016 - Elsevier
A classical symptom of rotating machines faults in vibration signals is the presence of
repetitive transients, whose distinctive signature is both impulsive and cyclostationary …

Cyclic spectral analysis of rolling-element bearing signals: Facts and fictions

J Antoni - Journal of Sound and vibration, 2007 - Elsevier
Rolling-element bearing vibrations are random cyclostationary. This property is so
symptomatic when an incipient fault develops that it can be exploited for diagnostics. This …
