Filtering of surface EMG using ensemble empirical mode decomposition [PDF]

open access: yesMedical Engineering & Physics, 2012
Surface electromyogram (EMG) is often corrupted by three types of noises, i.e. power line interference (PLI), white Gaussian noise (WGN), and baseline wandering (BW). A novel framework based primarily on empirical mode decomposition (EMD) was developed to reduce all the three noise contaminations from surface EMG.

A pixel-level entropy-weighted image fusion algorithm based on bidimensional ensemble empirical mode decomposition

open access: yesInternational Journal of Distributed Sensor Networks, 2018
The bidimensional empirical mode decomposition algorithm is more suitable to handle image fusion than the traditional multi-scale decomposition methods in the image fusion area.

A Human ECG Identification System Based on Ensemble Empirical Mode Decomposition [PDF]

open access: yesSensors, 2013
In this paper, a human electrocardiogram (ECG) identification system based on ensemble empirical mode decomposition (EEMD) is designed. A robust preprocessing method comprising noise elimination, heartbeat normalization and quality measurement is proposed to eliminate the effects of noise and heart rate variability.

Trends and Spatial Patterns of Drought Affected Area in Southern South America [PDF]

open access: yes, 2014
Based on 56 rainfall stations, which cover the period 1961–2008, we analyzed the presence of trends in the drought-affected area over southern South America (SSA) at different time scales.

Spectral proper orthogonal decomposition and its relationship to dynamic mode decomposition and resolvent analysis [PDF]

open access: yes, 2018
We consider the frequency domain form of proper orthogonal decomposition (POD) called spectral proper orthogonal decomposition (SPOD). Spectral POD is derived from a space-time POD problem for statistically stationary flows and leads to modes that each ...

Improved Ensemble Empirical Mode Decomposition and Its Application [PDF]

open access: yesProceedings of The 5th International Conference on Computer Engineering and Networks — PoS(CENet2015), 2015
A white noise parameter and a number of ensembles for EEMD adaptively obtained method (Adaptive Ensemble Empirical Mode Decomposition, AEEMD) is proposed to tackle the problem that the EEMD parameters are inaccurately chosen by the people’s experience.

A New Decomposition Ensemble Learning Approach with Intelligent Optimization for PM2.5 Concentration Forecasting

open access: yesDiscrete Dynamics in Nature and Society, 2020
In this study, we focus our attention on the forecasting of daily PM2.5 concentrations. According to the principle of “divide and conquer,” we propose a novel decomposition ensemble learning approach by integrating ensemble empirical mode decomposition ...
