Detection method of interharmonic pairs-caused voltage peak fluctuation flicker
Energy Reports, 2022 Interharmonics of high frequency will cause voltage’s peak value fluctuation, which will result in flicker of fluorescent lamp and LED lamp. To realize accurate evaluation of the flicker, a method based on multiresolution S-transform is proposed to ...

The Nitroglycerin-Flicker Test [PDF]
Circulation, 1951 The nitroglycerin-flicker test, as suggested and modified by Krasno and Ivy, has been used to test normal individuals and patients with a variety of cardiovascular diseases. The hypothesis that this test would serve as an index of the presence of vascular disease or spasm elsewhere in the body than the retina was explored.

A Lightweight Procedural Layer for Hybrid Experimental–Computational Workflows in Materials Science
Advanced Engineering Materials, EarlyView.We unveil a prototype hybrid‐workflow framework that fuses automatedcomputation with hands‐on experiments. Built atop pyiron, a lightweight, parameterized layer translates procedure descriptions into executable manual steps, syncing instrument settings, human interventions, and data capture in real‐time today.

Investigation of Reactive Power Control Effects on Flicker and Harmonics Emission of a DFIG Wind Turbine [PDF]
Journal of Intelligent Procedures in Electrical Technology, 2013 One of the most important power quality aspects in wind farms is voltage fluctuation or flicker which should be investigated due to the nature of wind speed variations. These variations result in power and voltage fluctuations at the load bus.

Advanced Engineering Materials, EarlyView.This work studies the anisotropic behavior of circular notched tensile specimens of Ni‐base superalloy single crystals during high‐temperature tensile creep along [001], [110], and [111]. Correlative scale‐bridging imaging of specimens reveals early rupture along [110] because 1) plastic deformation proceeds faster at notch center; 2) more (brittle ...

A Practical Noise2Noise Denoising Pipeline for High‐Throughput Raman Spectroscopy
Advanced Engineering Materials, EarlyView.A lightweight and reproducible denoising pipeline for high‐throughput Raman spectroscopy is introduced, based on a 1D convolutional autoencoder trained with a Noise2Noise strategy. Using only repeated short‐exposure acquisitions, the method suppresses stochastic noise without reference spectra, enabling reliable spectral reconstruction while preserving

Impact of MgO Additions on the Oxidation Resistance and Compression Behavior of Vanadium Alloys
Advanced Engineering Materials, EarlyView.An increase in oxidation resistance at 600 °C is achieved for alloys containing more than 2.5 wt.% MgO. It has been established that, along with V2O5, MgO6V2, and Mg2O7V2 are formed, which are presumed to enhance oxidative stability. Furthermore, the possible transformation of Mg‐vanadates through reaction with CO2, which presumably occurs in this ...
