Comparison of methods for the identification of mesoscale wind speed fluctuations
Mesoscale wind speed fluctuations influence the characteristics of offshore wind energy. These recurring wind speed changes on time scales between tens of minutes and six hours lead to power output fluctuations. In order to investigate the meteorological

Energy‐Based Phase‐Locking State Analysis in Brain State Identification
EPLSA constructs an energy landscape from BOLD phase synchrony, achieving superior brain state classification and providing novel stability metrics. It demonstrates strong clinical translatability in characterizing sleep–wake transitions and Alzheimer's disease.

Induction Motor Multi-Fault Analysis Based on Intrinsic Mode Functions in Hilbert-Huang Transform [PDF]
This paper reports experimental studies to detect two faults in a 3-phase 1.5hp induction motor using intrinsic mode functions from Hilbert-Huang transform. The faults studied are the eccentricity of the air-gap between the rotor and stator and damage to

Hilbert-Huang Transform Based Approach for Measurement of Voltage Flicker Magnitude and Frequency [PDF]
Voltage flicker is a non-stationary waveform for which direct spectral analysis is not appropriate. To overcome this difficulty, a Hilbert-Huang transform based technique is proposed here.

Abstract Wheat (Triticum aestivum L.), a foundation of global food security, faces persistent threats from stripe rust caused by Puccinia striiformis f. sp. tritici (Pst). The pathogen thrives in cool and humid environments and regularly causes epidemics that lead to severe yield losses.

Signal denoising optimization based on a Hilbert-Huang transform-triple adaptable wavelet packet transform algorithm [PDF]
The Hilbert-Huang transform (HHT) can retain intrinsic signal characteristics after noise reduction but still leaves a slightly noisy signal, and the wavelet packet transform (WPT) denoising algorithm eliminates noise efficiently but causes distortion of

Cutting force response in milling of Inconel: analysis by wavelet and Hilbert-Huang Transforms
We study the milling process of Inconel. By continuously increasing the cutting depth we follow the system response and appearance of oscillations of larger amplitude.

Brain Topography Method based on Hilbert-Huang Transform
Abstract The development of portable and wireless instruments that measure the electrical activity of the cerebral cortex (EEG) allows the capture and analysis of neurobiological signals in multiple applications. A lot of neurological, psychological and psychiatric disorders have been evaluated by EEG.

Abstract Rice (Oryza sativa) is an important staple food, feeding more than half of the global population. A feasible improvement of rice yield is necessary to meet the ever–growing food demands. Genomic selection (GS), as an advanced breeding technique, enables the prediction of phenotypes solely based on genotypic data using a constructed genomic ...

Operation of the Hilbert-Huang Transform: basic overview with examples [PDF]
This learning object provides a simple explanation of the operation of the Hilbert-Huang transform. This is a tool which has been employed with success in the signal processing field and, more especifically, in the analysis of non-stationary signals. The
