Structural damage identification

This paper presents two approaches for structural damage identification, each based on a different philosophy. The Virtual Distortion Method is a model-updating method of damage assessment, utilizing gradient-based optimization techniques to solve the resulting inverse dynamic problem in the time domain. Case-Based Reasoning is a soft-computing method utilizing wavelet transformation for signal processing and neural networks for training a base of damage cases to use for retrieving a similar relevant case.

Progress In Magnetostrictive Sonar Transducers

Continous interest from the French Navy (DRET and CERDSM) has permitted significant improvements to magnetostrictive transducers in order to produce low-frequency high-power sonar sources. These improvements can be appreciated by looking at three transducers.
