Spectral Estimation of Noisy Seismogram using Time-Frequency Analyses

Devi, Vaneeta; Sharma, M. L. - In: International Journal of Geotechnical Earthquake … 7 (2016) 1, pp. 19-32

Time–Frequency analyses have the advantage of explaining the signal features in both time domain and frequency domain. This paper explores the performance of Time–Frequency analyses on noisy seismograms acquired from seismically active region in NW Himalayan. The Short Term Fourier...

Wind turbine fault diagnosis based on Morlet wavelet transformation and Wigner-Ville distribution

Tang, Baoping; Liu, Wenyi; Song, Tao - In: Renewable Energy 35 (2010) 12, pp. 2862-2866

Based on the Morlet wavelet transformation and Wigner-Ville distribution (WVD), we present a wind turbine fault …-known technology applied in wind turbine condition monitoring, in which the time-frequency analysis techniques such as Wigner-Ville … distribution (WVD) are widely used. Theoretically WVD has an infinite resolution in time-frequency domain. For early wind turbine …
