EMD-Based Filtering Using Similarity Measure Between Probability Density Functions of IMFs [PDF]

open access: yes, 2014
This paper introduces a new signal-filtering which combines the empirical mode decomposition (EMD) and a similarity measure. A noisy signal is adaptively broken down into oscillatory components called intrinsic mode functions (IMFs) by EMD followed by an

Suppressing the Zero-Frequency Components in Single Quantitative Phase Imaging by Filtering the Low-Frequency Intrinsic Mode Function Components

open access: yes, 2023
In off-axis quantitative phase imaging, existing methods of suppressing the zero-frequency component (ZFC) always cause the loss of high-frequency phase information, thus degrading the accuracy of phase reconstruction.

Energy of intrinsic mode function for gas-liquid flow pattern identification

open access: yes, 2012
Gas-liquid flows abound in a great variety of industrial processes. Correct recognition of the regimes of a gas-liquid flow is one of the most formidable challenges in multiphase flow measurement.

The sodium-potassium pump controls the intrinsic firing of the cerebellar Purkinje neuron [PDF]

open access: yes, 2012
In vitro, cerebellar Purkinje cells can intrinsically fire action potentials in a repeating trimodal or bimodal pattern. The trimodal pattern consists of tonic spiking, bursting, and quiescence.

Hour-Ahead Wind Speed and Power Forecasting Using Empirical Mode Decomposition

open access: yesEnergies, 2013
Operation of wind power generation in a large farm is quite challenging in a smart grid owing to uncertain weather conditions. Consequently, operators must accurately forecast wind speed/power in the dispatch center to carry out unit commitment, real ...

Pressure fluctuation signal analysis of pump based on ensemble empirical mode decomposition method

open access: yesWater Science and Engineering, 2014
Pressure fluctuations, which are inevitable in the operation of pumps, have a strong non-stationary characteristic and contain a great deal of important information representing the operation conditions.

The research progress of empirical mode decomposition and mode mixing elimination

open access: yesDianzi Jishu Yingyong, 2019
The Empirical Mode Decomposition(EMD) algorithm proposed by Huang is a data driven adaptive analysis method for nonlinear time-varying signals. The signals can be decomposed into a few Intrinsic Mode Functions(IMFs) components with physical meaning ...

Spectral Correlation Measure for Selecting Intrinsic Mode Functions [PDF]

open access: yes, 2014
Time series analysis implies extracting relevant features from real-world applications to improve pattern recognition tasks. In that sense, representation methods based on time series decomposition and similarity measures are combined to select representative features with physical interpretability.
