Surveys in Mathematics and its Applications, 2021 The Hilbert transform is essentially the only singular operator in one dimension. This undoubtedly make it one of the most important linear operator in harmonic analysis.

IET Image Processing, 2021 Building on past work showing that the Hilbert transform can be used for edge feature enhancement, a new edge feature enhancement method is developed using a two‐dimensional (2D) isotropic Hilbert transform of the Cauchy distribution.

Archives of Metallurgy and Materials, 2015 In this work, we present a novel Hilbert-twin method to compute an envelope and the logarithmic decrement, δ, from exponentially damped time-invariant harmonic strain signals embedded in noise.

Time-Frequency Analysis of Noisy Vibration Signal Based on Improved Hilbert-Huang Transform
Shanghai Jiaotong Daxue xuebao, 2023 Aimed at the phenomenon of modal confusion and lack of practical significance of instantaneous frequency caused by Hilbert-Huang transform (HHT) noisy vibration signal time-frequency analysis, complete ensemble empirical mode decomposition with adaptive ...

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.

On Finite Hilbert Transforms [PDF]
Transactions of the American Mathematical Society, 1975 Let E be a bounded measurable subset of the real line. The finite Hilbert transform is the operator HE defined on one of the spaces LP(E) (1 1, the Hilbert transform of f at x is defined by (1) Hf(x) = li (rmi) f f(tXt -x) 1dt, provided this latter limit exists. It is known that if f is in LP(R), for p > 1, then Hf exists a.e.

Tschirnhaus transformations after Hilbert [PDF]
L’Enseignement Mathématique, 2021 In this paper, we use enumerative geometry to simplify the formula for the roots of the general one-variable polynomial of degree n , for all n .
