Outlier detection based on Hilbert-Huang Transform

2011 International Conference on Remote Sensing, Environment and Transportation Engineering, 2011
In this paper, we review the main concept and the developing method of Hilbert-Huang Transform (HHT), which is the novel and high-efficiently nonlinear and non-stationary data analysis method. HHT is composed of Empirical Mode Decomposition(EMD) and Hilbert Spectral Analysis(HSA).

Detection of the instantaneous frequency degradation due to damages of a fixed offshore jacket platform using the iEEMD‐based Hilbert Huang transform under a wave excitation

Structural Control & Health Monitoring, 2022
In online structural health monitoring of the fixed offshore jacket platform, the determination of the time‐dependent degradation of structures due to damages is the most important step in a maintenance strategy.

Hilbert-Huang transform in MHD plasma diagnostics

Plasma Physics Reports, 2005
A new method for processing experimental data from MHD diagnostics is discussed that provides a more detailed study of the dynamics of large-scale MHD instabilities. The method is based on the Hilbert-Huang transform method and includes an empirical mode decomposition algorithm, which is used to decompose the experimental MHD diagnostic signals into a ...

Travelling wave fault location algorithm for LCC-MMC-MTDC hybrid transmission system based on Hilbert-Huang transform

International Journal of Electrical Power & Energy Systems, 2020
The paper looks through the fault location algorithm of multi-terminal direct-current (MTDC) hybrid transmission systems based on line-commutated converter (LCC) and modular multi-level converter (MMC).

Generator Coherency Using the Hilbert–Huang Transform

IEEE Transactions on Power Systems, 2008
Coherency between generators is tracked, by examining the instantaneous phase differences among interarea oscillations and swing curves in disturbed multiarea power systems. Huang's empirical mode decomposition is applied to extract dominant oscillatory modes from interarea oscillations/swing curves.

Hilbert-Huang Transform and Wavelet Transform for ECG Detection

2008 4th International Conference on Wireless Communications, Networking and Mobile Computing, 2008
HHT (Hilbert transform) and wavelet transform are both signal processing methods. This paper is based on HHT and wavelet transform to detect R peak. Firstly using wavelet transform to de-noise, then we are focus on using the empirical mode decomposition (EMD) to electrocardiogram (ECG) which can be decomposed into a limited number of IMF (intrinsic ...

Hilbert-Huang Transformation based solar light noise suppression method

2015 4th International Conference on Computer Science and Network Technology (ICCSNT), 2015
Solar light noise, as the main part of channel noise in outdoor visible light communication (VLC) system, would easily saturate the photon-detector, and dramatically decrease the outdoor VLC system performance. A Hilbert-Huang Transformation based solar light noise suppression method is proposed in this paper, a background light noise measurement ...
