.... for the response reconstruction in the substructure from the frequency and wavelet domain methods, respectively. Note that in the frequency domain method, FFT is used to transform the time domain signals into the frequency domain, while discrete wavelet transform is used in the wavelet domain method. Step 5...

...L. Zhang; S. T. Quek; Q. Wang, Mem. ASME The applicability of Gabor wavelet transform of time history data in detecting a thin damage in beam is examined. For the case where the damage position is completely unknown, the use of two load positions is suggested. Cases considered are the position...

...-dimensional problems. The solution of the elastostatics system by this kind of method is not usual ( 3 4 ). Boundary problems on open bounded sets are very difficult to treat ( 5 ). Nevertheless, periodic conditions on elementary bounded sets are natural for the use of wavelet transform. In this paper, we...
