چکیده

This paper is devoted to an analysis of environmental time series using the empirical mode decomposition (EMD) method. This is a new method, which was developed for the off-line analysis of non-stationary and stochastic signals. The purpose of the work was to modify the EMD algorithm for on-line analysis and to find out the states of ecosystems in real time. The practical realization of the algorithm was implemented using the MATLAB software and its simulation toolbox, SIMULINK. The modified algorithm was verified using the environmental data that was measured by meteorological stations deployed in the southern part of the Czech Republic. The results obtained are shown graphically.

A Fault Diagnosis Method for Automaton based on Morphological Component Analysis and Ensemble Empirical Mode Decomposition

In the fault diagnosis of automaton, the vibration signal presents non-stationary and non-periodic, which make it difficult to extract the fault features. To solve this problem, an automaton fault diagnosis method based on morphological component analysis (MCA) and ensemble empirical mode decomposition (EEMD) was proposed. Based on the advantages of the morphological component analysis method i...

Blind Voice Separation Based on Empirical Mode Decomposition and Grey Wolf Optimizer Algorithm

Blind voice separation refers to retrieve a set of independent sources combined by an unknown destructive system. The proposed separation procedure is based on processing of the observed sources without having any information about the combinational model or statistics of the source signals. Also, the number of combined sources is usually predefined and it is difficult to estimate based on the ...
