A team led by UCSD structural engineering professor Francesco Lanza di Scalea describes in the Aug. 22 issue of the Journal of Sound and Vibration a defect-detection technique that uses laser beam ...

MFL is an inferred method of wall measurement. Ultrasonic measurement, on the other hand, is a more direct measurement of remaining wall thickness using a technique similar to sonar.

Ultrasound imaging offers several advantages over conventional x-rays for periodontal applications, said Osama Mukdadi, Ph.D., an assistant professor of mechanical and aerospace engineering in the ...

Frequent fires caused by Li-ion batteries have drawn attention to the timely detection of defects that cause thermal acceleration and cannot be detected by the naked eye. Researchers from Drexel ...
