Dmey wavelet
WebFor Figure 9c, between the indices that used the kurtosis index as the denoising method, the maximum kurtosis value was reached by Index 154 (dmey as the mother wavelet), while considering all parameter sets that used the threshold method (Indices 1–150), Index 92 gave the highest kurtosis value, with a difference of 19.7% with respect to ...

WebNov 21, 2024 · Out of four tested approaches, the study advocates the use of relative weight analysis (RWA) for the selection of dominant input wavelet sub-series in the development of wavelet-coupled models. The db8 and the dmey (Discrete approximation of Meyer) wavelet functions at level nine were found to provide the best performance with the RWA approach. WebNov 1, 2024 · The comparison results showed that dmey wavelet provides the maximum Energy and Energy to Shannon Entropy ratio, so it is selected as the best wavelet for CWT analysis. Fig. 8 demonstrates the comparison results between five wavelet types. Hence, dmey wavelet with 8 decomposition level was used to analyze the engine vibrations.
