Artifact reduction in multichannel pervasive EEG using hybrid WPT-ICA and WPT-EMD signal decomposition techniques [PDF]

open access: yes, 2014
In order to reduce the muscle artifacts in multi-channel pervasive Electroencephalogram (EEG) signals, we here propose and compare two hybrid algorithms by combining the concept of wavelet packet transform (WPT), empirical mode decomposition (EMD) and ...

EEMD Independent Extraction for Mixing Features of Rotating Machinery Reconstructed in Phase Space

open access: yesSensors, 2015
Empirical Mode Decomposition (EMD), due to its adaptive decomposition property for the non-linear and non-stationary signals, has been widely used in vibration analyses for rotating machinery.

Research on Dynamic Measurement Method of Flow Rate in Tea Processing

open access: yesSensors, 2022
Tea flow rate is a key indicator in tea production and processing. Due to the small real−time flow of tea leaves on the production line, the noise caused by the transmission system is greater than or close to the real signal of tea leaves. This issue may

Improved EMD Using Doubly-Iterative Sifting and High Order Spline Interpolation [PDF]

open access: yes, 2008
Empirical mode decomposition (EMD) is a signal analysis method which has received much attention lately due to its application in a number of fields. The main disadvantage of EMD is that it lacks a theoretical analysis and, therefore, our understanding ...

Multimode Decomposition and Wavelet Threshold Denoising of Mold Level Based on Mutual Information Entropy

open access: yesEntropy, 2019
The continuous casting process is a continuous, complex phase transition process. The noise components of the continuous casting process are complex, the model is difficult to establish, and it is difficult to separate the noise and clear signals ...
