Adaptive Mode Decomposition Methods and Their Applications in Signal Analysis for Machinery Fault Diagnosis: A Review With Examples

open access: yesIEEE Access, 2017
Effective signal processing methods are essential for machinery fault diagnosis. Most conventional signal processing methods lack adaptability, thus being unable to well extract the embedded meaningful information.

Analysis of rock microseismic signal based on blind source wavelet decomposition algorithm

open access: yesAIP Advances, 2022
At present, microseismic technology is a widely used method for monitoring the rock burst phenomenon during the construction of deep-buried tunnels. The rock fracture in the tunnel will generate seismic waves.

Tensor Decomposition for EEG Signals Retrieval [PDF]

open access: yes2019 IEEE International Conference on Systems, Man and Cybernetics (SMC), 2019
Prior studies have proposed methods to recover multi-channel electroencephalography (EEG) signal ensembles from their partially sampled entries. These methods depend on spatial scenarios, yet few approaches aiming to a temporal reconstruction with lower loss.

Codage des signaux par EMD [PDF]

open access: yes, 2012
In this letter a new signals coding framework based on the Empirical Mode Decomposition (EMD) is introduced. The EMD breaks down any signal into a reduced number of oscillating components called Intrinsic Modes Decomposition (IMFs).
