Fast non-recursive extraction of individual harmonics using artificial neural networks [PDF]
, 2005 A collaborative work between Northumbria University and University of Peradeniya (Sri Lanka). It presents a novel technique based on Artificial Neural Networks for fast extraction of individual harmonic components. The technique was tested on a real-time

DEVELOPMENT AND INVESTIGATION OF FILTRATION METHODS OF MANY-PHASE INDETERMINATE SIGNALS
Міжнародний науково-технічний журнал "Проблеми керування та інформатики", 2007 The pick out algorithms of the main harmonics from many-phase signals, which are subjected to influence of high-frequency noises and unknown constant displacements, are developed and investigated. The algorithms demand neither external information about

FEBS Open Bio, EarlyView.Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

A Digital Technique for Online Identification and Tracking of Power System Harmonics Based on Real Coded Genetic Algorithm [PDF]
, 2006 Current and voltage waveforms of a distribution or a transmission system are not pure sinusoids. There are distortions in these waveforms that consist of a combination of the fundamental frequency, harmonics and high frequency transients.

Fast-responding measurements of power system harmonics using discrete and fast fourier transforms with low spectral leakage [PDF]
, 2011 Conventional wisdom dictates that a Fast Fourier Transform (FFT) will be a more computationally effective method for measuring multiple harmonics than a Discrete Fourier Transform (DFT) approach.

Advanced Engineering Materials, EarlyView.A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.
