Archives 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.

Extended Hilbert Transform and Application for Seismic Attributes
Earth 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.

Fuzzy Hilbert Transform of Fuzzy Functions
MathematicsThis paper studies the properties of the Fourier transform of the fuzzy function, and extends the classical Poisson integral formula on the half plane to the fuzzy case, obtaining the composition of the fuzzy set generated by a point in the complex field

Complex Hilbert Transform Filter [PDF]
Journal of Signal and Information Processing, 2011 Hilbert transform is a basic tool in constructing analytical signals for a various applications such as amplitude modulation, envelope and instantaneous frequency analysis, quadrature decoding, shift-invariant multi-rate signal processing and Hilbert-Huang decomposition.

Averages of simplex Hilbert transforms [PDF]
Proceedings of the American Mathematical Society, 2020 We study a multilinear singular integral obtained by taking averages of simplex Hilbert transforms. This multilinear form is also closely related to Calder n commutators and the twisted paraproduct. We prove $L^p$ bounds in dimensions two and three and give a conditional result valid in all dimensions.
