A general framework for wave separation in the frequency domain [PDF]

open access: yesCoastal Engineering, 2020
A general framework for wave separation in the frequency domain is presented and evaluated with successful results using theoretical examples of nonlinear waves. This framework consists of a qualitative and a quantitative analysis.

Equilibrium Theory–Based Analysis of Nonlinear Waves in Separation Processes

Annual Review of Chemical and Biomolecular Engineering, 2013
Different areas of engineering, particularly separation process technology, deal with one-dimensional, nonstationary processes that under reasonable assumptions, namely negligible dispersion effects and transport resistances, are described by mathematical models consisting of systems of first-order partial differential equations.

Hierarchical wave-mode separation in the poroelastic medium using eigenform analysis

Geophysics, 2022
ABSTRACT In the elastic medium, the scalar and vector P- and S-waves decomposition has been extensively studied and some strategies can be extended to the poroelastic medium to extract P- and S-wavefields. However, there are three propagation modes in the poroelastic medium in Biot’s theory, namely, a fast P wave, a slow P wave, and ...

Time-frequency analysis - a new tool for waves separation

54th EAEG Meeting, 1992
Non stationary signal processing methods are usualy applied to characterize dispersive signals. The authors are implied in studiyng surface-waves which energetic time frequency representation exhibits several patterns. In a first time, non related Fourier time-frequency methods (Sliding Lagunas method) is used to characterize different waves.
