A mathematical and numerical framework for ultrasonically-induced Lorentz force electrical impedance tomography [PDF]
, 2014 We provide a mathematical analysis and a numerical framework for Lorentz force electrical conductivity imaging. Ultrasonic vibration of a tissue in the presence of a static magnetic field induces an electrical current by the Lorentz force.

Using Support Vector Machine to Improve Ultrasonic Pulse Velocity Test for Concrete
MATEC Web of Conferences, 2018 In the construction industry, to evaluate the compressive strength of concrete, destructive and non-destructive testing methods are used. Non-destructive testing methods are preferable due to the fact that those methods do not destroy concrete samples ...

Dimension Effect on the Ultrasonic Pulse Velocity
International Journal of Geography and Geology, 2017 Ultrasonic pulse velocity test is non-destructive and relatively simple to carry out at both in-situ and laboratory conditions. The sonic velocity (SV) test has been used to determine the dynamic properties of rocks in different applications of rock and geotechnical engineering.
