ENO-wavelet transforms for piecewise smooth functions [PDF]
, 2002 We have designed an adaptive essentially nonoscillatory (ENO)-wavelet transform for approximating discontinuous functions without oscillations near the discontinuities. Our approach is to apply the main idea from ENO schemes for numerical shock capturing

Comparison between the Heun's and Haar Wavelet Methods for solution Differential-Algebraic Equations (DAEs) [PDF]
Al-Rafidain Journal of Computer Sciences and Mathematics, 2009 In this paper, We solved the system of differential-algebraic equation (DAEs) of index one numerically with Heun's method and operational matrices of Haar wavelet method, When we compared the results of the two methods with the exact solution, show that ...

A Comparative Study using Scale-2 and Scale-3 Haar Wavelet for the Solution of Higher Order Differential Equation [PDF]
International Journal of Mathematical, Engineering and Management Sciences, 2023 A comparative study of scale-2 and scale-3 Haar wavelet has been presented to illustrate the level of accuracy attained by both the wavelets by applying on higher order differential equations known as Emden fowler equation, which has great importance in ...

Simulation of Field Theories in Wavelet Representation [PDF]
, 1994 The field is expanded in a wavelet series and the wavelet coefficients are varied in a simulation of the 2D $\phi^4$ field theory. The drastically reduced autocorrelations result in a substantial decrease of computing requirements, compared to those in ...

Feedback Control Method Using Haar Wavelet Operational Matrices for Solving Optimal Control Problems
Abstract and Applied Analysis, 2013 Most of the direct methods solve optimal control problems with nonlinear programming solver. In this paper we propose a novel feedback control method for solving for solving affine control system, with quadratic cost functional, which makes use of only ...

Simulation of a non‐linear, time‐variant circuit using the Haar wavelet transform
IET Science, Measurement & Technology, 2022 Wavelet theory has disentangled numerous complexities, including those pertinent to transient and steady‐state responses of systems, when Laplace and Fourier transforms face insoluble obstacles. Reactive linear components (e.g.

Approximations to linear Klein–Gordon Equations using Haar wavelet
Ain Shams Engineering Journal, 2021 In this research article, two Haar wavelet collocation methods (HWCMs) (namely one dimensional HWCM and two dimensional HWCM) are adapted to approximate linear homogeneous and linear non-homogeneous Klein–Gordon equations.

DWT/PCA face recognition using automatic coefficient selection [PDF]
, 2008 In PCA-based face recognition, there is often a trade-off between selecting the most relevant parts of a face image for recognition and not discarding information which may be useful.
