Analysis of Surface Roughness Influence in Non-Destructive Magnetic Measurements Applied to Reactor Pressure Vessel Steels

open access: yesApplied Sciences, 2020
The influence of surface roughness on magnetic measurements of Reactor Pressure Vessel Steels was investigated by applying two types of magnetic, non-destructive measurement on nuclear reactor pressure vessel steel samples: magnetic adaptive testing (MAT)

Machine-Learning Approach to Determine Surface Quality on a Reactor Pressure Vessel (RPV) Steel

open access: yesApplied Sciences, 2022
Surface quality measures such as roughness, and especially its uncertain character, affect most magnetic non-destructive testing methods and limits their performance in terms of an achievable signal-to-noise ratio and reliability. This paper is primarily

Influence of magnetizing current speed in magnetic adaptive testing

open access: yesJournal of Electrical Engineering, 2018
Abstract Influence of changing rate of magnetizing current in magnetic adaptive testing was studied. Sensitivity of magnetic descriptors, which characterize the samples degradation, was found to depend on this speed. Low speed results in a better sensitivity, but the effect depends on permeability of the investigated specimens ...

Nondestructive characterization of flake graphite cast iron by magnetic adaptive testing [PDF]

open access: yesNDT & E International, 2015
Abstract Three series of flake graphite cast iron samples having different chemical compositions and different heat treatments within each series were investigated by the method of magnetic adaptive testing. The flat samples were magnetized by an attached yoke, and sensitive descriptors were obtained from the proper evaluation, based on the ...

Development of magnetorheological fluids within 3D printed elastomeric cellular structures with an accumulator

open access: yesAIP Advances, 2023
In this study, a magnetorheological fluid (MRF) was encapsulated in a 3D printed cellular elastomeric encapsulant. Mechanical properties, such as stiffness and damping, of the encapsulant containing MRFs can be controlled via applied magnetic field. Such

Comparison between adaptive and fixed stimulus paired-pulse transcranial magnetic stimulation (ppTMS) in normal subjects

open access: yesClinical Neurophysiology Practice, 2017
Objectives: Paired-pulse TMS (ppTMS) examines cortical excitability but may require lengthy test procedures and fine tuning of stimulus parameters due to the inherent variability of the elicited motor evoked potentials (MEPs) and their tendency to ...

Active and resting motor threshold are efficiently obtained with adaptive threshold hunting. [PDF]

open access: yesPLoS ONE, 2017
Transcranial magnetic studies typically rely on measures of active and resting motor threshold (i.e. AMT, RMT). Previous work has demonstrated that adaptive threshold hunting approaches are efficient for estimating RMT.
