Thermal Image Enhancement using Bi-dimensional Empirical Mode Decomposition in Combination with Relevance Vector Machine for Rotating Machinery Fault Diagnosis [PDF]

, 2009
In this study, a novel fault diagnosis system for rotating machinery using thermal imaging is proposed. This system consists of bi-dimensional empirical mode decomposition (BEMD) for image enhancement, a generalized discriminant analysis (GDA) for ...

A Minimum Arclength Method for Removing Spikes in Empirical Mode Decomposition

IEEE Access, 2019
Empirical mode decomposition (EMD) is an extensively utilized tool in a time-frequency analysis. However, disturbances, such as impulse noise, can result in a mode-splitting effect, in which one physically meaningful component is split into two or more ...

Output-Only Modal Analysis Based on Improved Empirical Mode Decomposition Method

Advances in Materials Science and Engineering, 2015
The output-only modal analysis for bridge structures based on improved empirical mode decomposition (EMD) is investigated in this study. First, a bandwidth restricted EMD is proposed for decomposing nonstationary output measurements with close frequency ...

Application of Empirical Mode Decomposition with Local Linear Quantile Regression in Financial Time Series Forecasting

The Scientific World Journal, 2014
This paper mainly forecasts the daily closing price of stock markets. We propose a two-stage technique that combines the empirical mode decomposition (EMD) with nonparametric methods of local linear quantile (LLQ). We use the proposed technique, EMD-LLQ,

Signal prediction based on empirical mode decomposition and artificial neural networks

Geodesy and Geodynamics, 2012
In view of the usefulness of Empirical Mode Decomposition (EMD), Artificial Neural Networks (ANN), and Most Relevant Matching Extension (MRME) methods in dealing with nonlinear signals, we propose a new way of combining these methods to deal with signal ...

Fault Diagnosis of Wind-turbine Gearboxes based on Fourier Decomposition Method

Jixie chuandong, 2018
The Empirical Mode Decomposition （EMD）,as an empirical method,lacks rigorous theoretical proof. For this reason,EMD in practical application is confronted by many problems,which make EMD hard to extract fault features from vibration data of complex wind ...

Quantification of Dynamic Properties of Pile Using Ensemble Empirical Mode Decomposition

Advances in Civil Engineering, 2018
This paper investigated dynamical interactions between pile and frozen ground by using the ensemble empirical mode decomposition (EEMD) method. Unlike the conventional empirical mode decomposition (EMD) method, EEMD is found to be able to separate the ...
