Numerical integration of the integrals based on Haar wavelets

, 2013
In this work, we present a computational method for solving double and triple integrals with variable limits of integrations which is based on Haar wavelets. This approach is the generalization and improvement of the methods [3].

Wavelets and the generalization of the variogram

, 2004
The experimental variogram computed in the usual way by the method of moments and the Haar wavelet transform are similar in that they filter data and yield informative summaries that may be interpreted. The variogram filters out constant values; wavelets

Numerical Solutions of Fractional System of Partial Differential Equations By Haar Wavelets

, 2015
In this paper, time fractional one dimensional coupled KdV and coupled modified KdV equations are solved numerically by Haar wavelet method. Proposed method is new in the sense that it doesn’t use fractional order Haar operational matrices.

Design of an operational matrix method based on Haar wavelets and evolutionary algorithm for time-fractional advection–diffusion equations

Open Engineering
In this study, we introduce an operational matrix (OM) method based on Haar wavelets (HWs) to approximate the solution of time-fractional advection–diffusion equations (TFADEs). These problems involve fractional derivatives in the Atangana–Baleanu Caputo

Constructing a quasilinear moving average using the scaling function [PDF]

The scaling function from multiresolution analysis can be used to constuct a smoothing tool in the context of time series analysis. We give a time series smoothing function for which we show the properties of a quasilinear moving average. Furthermore; we

Wavelets obtained by continuous deformation of the Haar wavelet

, 1996
One might obtain the impression, from the wavelet literature, that the class of orthogonal wavelets is divided into subclasses, like compactly supported ones on one side, band-limited ones on the other side. The main purpose of this work is to show that,

Phase-shifting Haar Wavelets For Image-based Rendering Applications

, 2008
In this thesis, we establish the underlying research background necessary for tackling the problem of phase-shifting in the wavelet transform domain. Solving this problem is the key to reducing the redundancy and huge storage requirement in Image-Based ...

Local filters of b-spline wavelets

, 2004
Haar wavelets have been widely used in Biometrics. One advantage of Haar wavelets is the simplicity and the locality of their decomposition and reconstruction filters.
