A new controller based on discrete wavelet packet transform (DWPT) for liquid level system (LLS) has been presented here. In this proposed controller, packet transform is used to decompose the error signal into different frequency nodes at various scales which represents many underlying phenomena ...

In this study, an improved forecasting accuracy for up to 3 weeks ahead of GWLs in Bangladesh was achieved by employing a coupled Long Short Term Memory (LSTM) network-based deep learning algorithm and Maximal Overlap Discrete Wavelet Packet Transform (MODWPT) data preprocessing. The coupled LSTM...
The paper aims to emphasize the importance of computer simulation in speech denoising area by comparing Fourier Transform to Discrete Wavelet Packet Transform. Wavelet Packet Coefficients have the ability to capture important localized time and frequency features of speech. For denoising, certain Wavelet ...
This extension mode corresponds to the classic discrete wavelet or wavelet packet transform where the signal length is restricted to a power of two. This mode produces the smallest length wavelet decomposition. If the signal length is odd andmodeis'per', an extra sample equal to the last value...
This paper discusses a novel technique for finger veins features extraction using Discrete Wavelet Packet Transform (DWPT) based method. The DWPT without HH subband decomposition is applied on ROI of 96×64 size finger veins image up to third level. The average standard deviation and average ...
