... and receiving usly many modes of the Lamb waves with broadband detection beams and the wavelet transform of various shapes of the mother wavelet, Gabor function. The method is applied for group velocity maps of the S0, A0, S1, A1, S2, A2 and A3 modes of the Lamb waves of thin aluminum plates. Also...

... decreases due to the coupled fluid mass. Coupling between the pipe wall and the fluid also decreases the sound speed in the fluid. Likewise, the speed of sound in fluid is frequency-dependent, just as the group velocity of bending waves depends on the frequency. Wavelet transform of non-stationary sound...
