The Hilbert-Huang Transform as a method and tool to support the analysis of non-linear and non-stationary electroencephalographic signals.
(Institute of Electrical and Electronics Engineers Inc., 2022)
The analysis of non-stationary and non-periodic signals has long been restricted to Fourier decomposition in the frequency domain. However, when bringing the frequency content to the time domain (STFT), harmonics appear ...
Diagnosis of bearing faults in induction motors by vibration signals-Comparison of multiple signal processing approaches
(2015-01-01)
Early detection of faults in the bearings of electric motors is vital to reduce maintenance costs of industrial motors. Vibration signal analysis is a well-known and widely used diagnostic approach for bearing fault ...

Orlicz boundedness for certain classical operators
(Institute of Mathematics - Polish Academy of Sciencies, 2002-06)
Let ɸ and ψ be functions defined on [0,∞) taking the value zero at zero and with non-negative continuous derivative. Under very mild extra assumptions we find necessary and sufficient conditions for the fractional maximal ...
A simple but efficient voice activity detection algorithm through Hilbert transform and dynamic threshold for speech pathologies
(IOP Publishing, 2016)
A simple but efficient voice activity detector based on the Hilbert transform and a dynamic threshold is presented to be used on the pre-processing of audio signals -- The algorithm to define the dynamic threshold is a ...
