Bi-angular lens for material characterization
(IEEE, 1994)In this paper a new lens design is proposed for characterization of layered materials. Lamb wave lens employs Lamb waves for this purpose since these waves propagate along interfaces. However, below cut-off angle, the ... -
Measurement of sensitivity of different wave modes to subsurface defects
(IEEE, 1988)Excitation of acoustic wave modes in a layered solid is investigated when the solid is immersed in a liquid. This is done by computing the reflection coefficient of acoustic plane waves at the liquid-layered-solid interface. ... -
Recognition of vessel acoustic signatures using non-linear teager energy based features
(IEEE, 2016-10)This paper proposes a vessel recognition and classification system based on vessel acoustic signatures. Teager Energy Operator (TEO) based Mel Frequency Cepstral Coefficients (MFCC) are used for the first time in Underwater ...
