A characterization of the Hilbert transform [PDF]
Proceedings of the American Mathematical Society, 1998 In this note the Hilbert transform is characterized in terms of function algebras with respect to pointwise multiplication. Let H be the Hilbert transform on the real line, 1 d Hf(x) = -P.V. f(X-) Y for x E R. H extends to a bounded linear operator on LP(R) for 1 < p < 00. There are several ways to characterize H.

Generalized multidimensional Hilbert transforms in Clifford analysis
International 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 ...

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.

Alternating Sunspot Area and Hilbert Transform Analysis [PDF]
Journal 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.

Fault Identification in Membrane Structures Using the Hilbert Transforms
Sensors, 2022 Fault diagnostics present a crucial technical issue in the areas of both the condition monitoring of machines and the monitoring of structural health. The identification of faults at an early stage in their development has an immense effect on the safety

Angewandte Chemie, EarlyView.Supported ultrasmall copper‐gold alloy nanoparticles are active heterogenous catalysts. In situ TEM tracking under oxygen at different temperatures reveals atomic‐scale dynamic phase structures, whereas combined operando synchrotron HE‐XRD and DRIFTS characterizations uncover ensemble‐averaged ordering/disordering phase structures and oscillatory ...

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.
