Validity and reliability of the haefni health system 1.0 device in the measurement of the isokinetic velocity range
(2014)
When rating any assessment protocol one of the key issues is to determine the validity and reliability of the devices used. The aim of this study was to analyze the validity and reliability of the variable velocity isokinetic ...
Determination of Phase Jumps in the Measurement of Phase Velocity of Samples Obeying a Frequency Power-Law Attenuation Coefficient Using Kramers-Kronig Relations
(2020-07-01)
Ultrasonic phase velocity spectroscopy is a very sensitive technique used in the measurement of material properties. In a phase velocity calculation, ambiguities can arise in the spectral phases, in the form of integer ...
