An Application to Transient Current Signal based Induction Motor Fault Diagnosis of Fourier-Bessel Expansion and Simplified Fuzzy ARTMAP [PDF]

open access: yes, 2013
The start-up transient signals have been widely used for fault diagnosis of induction motor because they can reveal early defects in the development process, which are not easily detected with the signals in the steady state operation. However, transient

Generalized multidimensional Hilbert transforms in Clifford analysis

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2006
Two specific generalizations of the multidimensional Hilbert transform in Clifford analysis are constructed. It is shown that though in each of these generalizations some traditional properties of the Hilbert transform are inevitably lost, new bounded ...

Critical Assessment Of The Issues In The Application Of Hilbert Transform To Compute The Logarithmic Decrement

open access: yesArchives of Metallurgy and Materials, 2015
The parametric OMI (Optimization in Multiple Intervals), the Yoshida-Magalas (YM) and a novel Hilbert-twin (H-twin) methods are advocated for computing the logarithmic decrement in the field of internal friction and mechanical spectroscopy of solids.

Alternating Sunspot Area and Hilbert Transform Analysis [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2011
We investigate the sunspot area data spanning from solar cycles 1 (March 1755) to 23 (December 2010) in time domain. For this purpose, we employ the Hilbert transform analysis method, which is used in the field of information theory.

SPECTRAL ESTIMATION OF TIME SERIES

open access: yesСовременная наука и инновации, 2022
As a result of spectral analysis, namely, the fast Fourier transform (FFT) method, the wavelet transform method, the Hilbert-Huang transform method, certain periods of the time series representing the monthly average values of the sunspot numbers were ...

Extended Hilbert Transform and Application for Seismic Attributes

open access: yesEarth and Space Science, 2019
The Hilbert transform (HT) has been widely used in seismic data processing and interpretation. However, HT results exhibit lower noise robustness and resolution.

Numerical Hilbert Transform Algorithm for Causal Interpolation of Functions Represented by Cubic and Exponential Splines

open access: yesIEEE Access, 2021
This paper presents an algorithm for numerical Hilbert transform of functions represented by cubic and exponential splines, which is suitable for causal interpolation of data spanning several frequency decades. It does not suffer from excessive number of
