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.

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-based valuation method for pricing European options
2022Summary: A numerical method based on the Haar wavelet is introduced in this study for solving the partial differential equation which arises in the pricing of European options. In the first place, and due to the change of variables, the related partial differential equation (PDE) converts into a forward time problem with a spatial domain ranging from 0

Haar wavelets basis method for Nash equilibrium strategies
2008 International Conference on Wavelet Analysis and Pattern Recognition, 2008Haar wavelets method for Nash equilibrium strategies of a time-varying linear-quadratic differential game problem is proposed. Based upon some useful properties of Haar wavelets, a special operation matrix of integration, product and coefficient matrices are applied to the government equation such that the cross-coupled Riccati matrix differential ...

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 ...

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.
