On the Engineering Mathematics Test (EMaT)

Journal of JSEE, 2007
The aim of Engineering Mathematics Test (EMaT) is to assess university students' core academic competence and acheivement of Engineering Mathematics. It is useful for professors to evaluate teaching effect of the classes. This evaluation would help them improve curricula, and scores can be available for graduate school entrance examination.

Fast Measurement of Magnetostriction Coefficients for Silicon Steel Strips Using Magnetostriction-Based EMAT

Sensors, 2018
Strain gauges and optical methods are commonly used to measure the magnetostriction coefficient of a sample. All these methods require a specific size sample and can only realize offline measurement, which is time-consuming.
