An optical method for production of Haar wavelet
Optics Communications, 2002The wavelet transform provides an efficient tool for signal processing. Haar wavelet is a good choice for the optical wavelet transform processor. An optical method for the production of Haar wavelet is proposed based on the grating filtering technique.

Numerical solution of Drinfel'd-Sokolov system with the Haar wavelets method
2022Summary: In this article, we use the Haar wavelets (HWs) method to numerically solve the nonlinear Drinfel'd-Sokolov (DS) system. For this purpose, we use an approximation of functions with the help of HWs, and we approximate spatial derivatives using this method.

RESOLUTION OF AN INVERSE PROBLEM BY HAAR BASIS AND LEGENDRE WAVELET METHODS
International Journal of Wavelets, Multiresolution and Information Processing, 2013In this paper, two numerical methods are presented to solve an ill-posed inverse problem for Fisher's equation using noisy data. These two methods are the Haar basis and the Legendre wavelet methods combined with the Tikhonov regularization method. A sensor located at a point inside the body is used and u(x, t) at a point x = a, 0 < a < 1 is ...

Evaluation of Haar wavelet method in engineering applications
AIP Conference Proceedings, 2019The results obtained by utilizing widely used Haar wavelet method (HWM) approach are compared with those obtained by finite difference method (FDM) and differential quadrature method (DQM). Latter methods (FDM and DQM) are considered as mainstream strong formulation based methods used in engineering design.

Haar wavelet method for the analysis of transistor circuits
AEU - International Journal of Electronics and Communications, 2007Abstract This paper presents Haar wavelet based method of analysis for observer design in the generalized state space or singular system of transistor circuits. The technique can be interpreted from the incremental and multiresolution view point. Accurate solutions can be obtained by changing the time scale ( m ) , at the same time the main ...
