Research on improved modal parameter identification method using Hilbert-Huang transform

Measurement + Control, 2023
In the wind tunnel test, the full-bridge aeroelastic model needs to simulate both the shape and dynamic characteristics of the real bridge, and modal parameters are key dynamic parameters.

Fault diagnosis method of a cascaded H‐bridge inverter based on a multisource adaptive fusion CNN‐transformer

IET Power Electronics, EarlyView.
The multisource adaptive fusion CNN‐transformer method proposed in this study can provide theoretical and technical support for fault diagnosis of high‐voltage MCHBI. It has a promising potential for engineering applications. Abstract In high‐voltage applications, the number of cascaded H‐bridge inverter units is large, the failure probability ...

Explicit constructions of short virtual resolutions of truncations

Bulletin of the London Mathematical Society, EarlyView.
Abstract We propose a concept of truncation for arbitrary smooth projective toric varieties and construct explicit cellular resolutions for nef truncations of their total coordinate rings. We show that these resolutions agree with the short resolutions of Hanlon, Hicks, and Lazarev, which were motivated by symplectic geometry, and we use our definition

Methods for detection and characterization of signals in noisy data with the Hilbert-Huang Transform

, 2009
The Hilbert-Huang Transform is a novel, adaptive approach to time series analysis that does not make assumptions about the data form. Its adaptive, local character allows the decomposition of non-stationary signals with hightime-frequency resolution but ...

Proximal‐dominant knee–ankle coordination compensations in football players with chronic ankle instability under high load

Journal of Experimental Orthopaedics, Volume 12, Issue 4, October 2025.
Load‐dependent alterations in knee–ankle coordination in football players with chronic ankle instability: This summarises a study investigating how chronic ankle instability (CAI) affects sagittal plane kinematics and knee–ankle coordination strategies under different loading conditions (walking and running) in male football players.

Resolving allogenic forcings on shallow‐marine sedimentary archives of the Taiwan Western Foreland Basin

Sedimentology, Volume 72, Issue 6, Page 1755-1785, October 2025.
ABSTRACT An investigation of allogenic forcings on shallow‐marine strata of the Miocene–Pliocene Kueichulin Formation, Taiwan Western Foreland Basin, reveals that shifts in palaeoenvironments were strongly controlled by: (1) orogenesis and basin subsidence, (2) precession‐driven hydroclimate and (3) obliquity‐driven atmospheric and ocean circulation ...

Arbitrary-order Hilbert spectral analysis for time series possessing scaling statistics: a comparison study with detrended fluctuation analysis and wavelet leaders

, 2011
In this paper we present an extended version of Hilbert-Huang transform, namely arbitrary-order Hilbert spectral analysis, to characterize the scale-invariant properties of a time series directly in an amplitude-frequency space. We first show numerically

Time-frequency representation of earthquake accelerograms and inelastic structural response records using the adaptive chirplet decomposition and empirical mode decomposition [PDF]

, 2007
In this paper, the adaptive chirplet decomposition combined with the Wigner-Ville transform and the empirical mode decomposition combined with the Hilbert transform are employed to process various non-stationary signals (strong ground motions and ...

Quantum Kernel Learning for Small Dataset Modeling in Semiconductor Fabrication: Application to Ohmic Contact

Advanced Science, Volume 12, Issue 35, September 18, 2025.
A quantum kernel‐aligned regressor (QKAR) is developed for modeling Ohmic contact formation in GaN HEMT fabrication. Leveraging experimental data and a Pauli‐Z feature map enhanced with a quantum kernel alignment (QKA) layer, the model achieves superior predictive performance over classical methods.

Open Source for Raman Spectroscopy Data Harmonization

Journal of Raman Spectroscopy, Volume 56, Issue 9, Page 878-881, September 2025.
Open‐source MIT–licensed Python package ramanchada2 collects existing and novel algorithms for generating Raman spectra, reading, visualizing, and processing, with emphasis on instrument calibration. It supports multiple input formats or experimental and simulated spectra and can generate synthetic spectra for data augmentation and benchmarking.
