Complex Singular Spectrum Decomposition and its Application to Rotating Machinery Fault Diagnosis

open access: yesIEEE Access, 2019
In recent years, singular spectrum decomposition (SSD) has been recognized as a powerful signal decomposition technique and has become a useful tool for fault signature extraction of rotating machinery.

Mesh and Model Adaptivity for Multiscale Elastoplastic Models With Prandtl‐Reuss Type Material Laws

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 127, Issue 6, 30 March 2026.
ABSTRACT Homogenization methods simulate heterogeneous materials like composites effectively, but high computational demands can offset their benefits. This work balances accuracy and efficiency by assessing model and discretization errors of the finite element method (FEM) through an adaptive numerical scheme.

An Improved Direct Torque Control with an Advanced Broken-Bar Fault Diagnosis for Induction Motor Drives

open access: yesInternational Transactions on Electrical Energy Systems, 2023
This paper presents an advanced strategy combining fuzzy logic and artificial neural networks (ANNs) for direct torque control (DTC) and broken-bar fault diagnosis in induction motors. More specifically, a fuzzy-based controller is used to simultaneously

Scrambling‐Enhanced Quantum Battery Charging in Black Hole Analogues

open access: yesAdvanced Science, Volume 13, Issue 11, 23 February 2026.
By employing a black‐hole‐analog quantum battery constructed from a position‐dependent XY model, its dynamical behavior is investigated through a quench of the scrambling parameter. It is systematically quantified that how the simulated scrambling improves key performance metrics‐namely, stored energy, peak power, and charging time‐thereby offering a ...

Weight Trajectories During Inpatient Treatment for Anorexia Nervosa: A Dynamic Time Warp Analysis

open access: yesInternational Journal of Eating Disorders, Volume 59, Issue 1, Page 169-178, January 2026.
ABSTRACT Background Restoring weight is a primary goal during anorexia nervosa (AN) treatment. Previous studies linked different weight gain profiles to treatment outcomes, but there is currently no consensus on profile shapes and numbers. We argue that heterogeneity stems from temporal distortions (“warping”) in weight gain, and that similar weight ...

Measurement-based solution for low frequency oscillation analysis

open access: yesJournal of Modern Power Systems and Clean Energy, 2016
This paper presents a measurement-based solution for low frequency oscillation (LFO) analysis in both real time monitoring and off-line case study. An online LFO property discrimination method is developed first, which alternately uses empirical mode ...

Multi‐Channel Convolutional Neural Quantum Embedding

open access: yesAdvanced Quantum Technologies, Volume 9, Issue 1, January 2026.
This study presents convolutional neural quantum embedding (CNQE), a framework for optimizing quantum data embeddings for multi‐channel data classification, grounded in quantum state discrimination and Fourier analysis of quantum circuits. CNQE is validated through proof‐of‐principle demonstrations on CIFAR‐10 and Tiny ImageNet, showing improved ...

EBMBDT: Effective Block Matching Based Denoising Technique using dual tree complex wavelet transform

open access: yesMachine Graphics & Vision, 2014
In processing and investigation of digital image denoising of images is hence very important. In this paper, we propose a Hybrid de-noising technique by using Dual Tree Complex Wavelet Transform (DTCWT) and Block Matching Algorithm (BMA).
