TL;DR: In this article, a wavelet transform-based technique was used to enhance defect de-tection in a carbon fiber composite plate interrogated using ultrasonic Lamb waves and incorporating an optical fiber receiver.

TL;DR: In this paper, the authors present a review of work conducted at The University of Strathclyde in collaboration with several European partners into the feasibility of Lamb wave inspection, addressing issues of Lamb Wave generation, propagation, defect interaction and detection.

TL;DR: The robustness of the networks to uncertainty in the input data was investigated using an interval-based technique, and it was demonstrated that the interval approach allowed for an alternative to probabilistic-based confidence bounds of prediction accuracy.

TL;DR: In this paper, a Lamb-wave inspection was used to diagnose damage in a composite plate, and both short-term and long-term experiments were carried out in order to examine the variations in normal condition as a result of run-in of the instrumentation and variations in ambient temperature.

TL;DR: A computer simulator to facilitate the design and assessment of a reconfigurable, air-coupled ultrasonic scanner is described and evaluated, and a theoretical image obtained from a team of sensing agents based on the current generation of sensors and instrumentation is presented.
