xiii, 78 p. : ill. (some col.) ; 30 cm. + 1 computer disc Wavelet transformation technique was founded to be more appropriate to analyse the AE signals under such situations. Wavelet transformation technique is used to de-noise the Acoustic Emission data. The de-noised signal is classified to identify a signature based on the type of phenomena. Through various filtering/thresholding techniques, it was found that the original signal was getting filtered out along with noise. There are many type of wavelet that can be used for de-noising data. However, daubechies wavelet is the most wavelet type is use in signal analysis compare to the other wavelet. A signal can be generates using one-dimensional wavelet packet analysis contain in MATLAB to verify the result of de-noising signal specialized Mohd Zul-Hilmi Bin Mohamad Project paper (Bachelor of Mechanical Engineering with Automotive) -- Universiti Malaysia Pahang - 2009 Bibliography : p. 52-53 Acoustic emission testing Wave packets THE0005712(Local) UMP 100622 20251114204432.0 vtls000046498
