“…A new tool for signal analysis -wavelet multiresolution time-scale method was recently implemented in NDT for concrete structures assessment [26][27][28]. It presents the next logic step in frequency analysis of signals -a STFT method of flexible size windows.…”

“…The study of the most appropriate technique for finding cracks in beams based on Wavelets signal processing was presented by Rucka and Wilde (Rucka, 2006). The proposed technique allows the position identification of the damage without the previous knowledge of the structure behavior or the use of mathematical models.…”

“…Several damages with different degrees of severity were investigated based on the optical measurement of the beams bending profile. The damage is located by identifying the local maxima of the signal components for each profile (Rucka, 2006). The Gaussian and Coifet Wavelet functions show to be the most effective in localizing the slot, up to 27% section reduction of the beam thickness.…”

“…Interpolation [24] and padding [25] methods are two types of manipulation to deal with this boundary effect. For simplicity in practice, another simple type of manipulation of vanishing abnormal wavelet coefficients [16,26] is employed in this study.…”
