Application of an Ultrasonic Sensor to Monitor Soil Erosion and Deposition [PDF]
, 2020 While erosion and deposition are naturally occurring processes, these processes can be accelerated by human influences. The acceleration of erosion causes damage to human assets and costs billions of dollars to mitigate.

A match coefficient approach for damage imaging in structural components by ultrasonic synthetic aperture focus [PDF]
, 2017 Ultrasonic Synthetic Aperture Focus (SAF) techniques are commonly used to image structural defects. In this paper, a variation of SAF based on ideas borrowed from Matched Field Processing (MFP) is evaluated to reduce artifacts and sidelobes of the ...
