The Haar Wavelet Approximation for the Two-Dimensional Time-Fractional Neuronal Dynamics Model

open access: yesFractal and Fractional
In this paper, we developed and constructed the Haar wavelet (HW) for the two-dimensional (2D) time-fractional neuronal dynamics model (TFNDM) with the dynamical electro-diffusion behaviour of ions in nerve cells. The Haar wavelet method is considered in

Assessment of Haar Wavelet-Quasilinearization Technique in Heat Convection-Radiation Equations

open access: yesApplied Computational Intelligence and Soft Computing, 2014
We showed that solutions by the Haar wavelet-quasilinearization technique for the two problems, namely, (i) temperature distribution equation in lumped system of combined convection-radiation in a slab made of materials with variable thermal conductivity

Fast Poisson Noise Removal by Biorthogonal Haar Domain Hypothesis Testing

open access: yes, 2008
Methods based on hypothesis tests (HTs) in the Haar domain are widely used to denoise Poisson count data. Facing large datasets or real-time applications, Haar-based denoisers have to use the decimated transform to meet limited-memory or computation-time

New Numerical Treatment for a Family of Two-Dimensional Fractional Fredholm Integro-Differential Equations

open access: yesAlgorithms, 2020
In this paper, we present a robust algorithm to solve numerically a family of two-dimensional fractional integro differential equations. The Haar wavelet method is upgraded to include in its construction the Laplace transform step.

Comparison of the Packet Wavelet Transform Method for Medical Image Compression

open access: yesJOIV: International Journal on Informatics Visualization, 2023
Medical images are often used for educational, analytical, and medical diagnostic purposes. Medical image data requires large amounts of storage on computers. Three types of codecs, namely Haar, Daubechies, and Biorthogonal, were used in this study. This

Haar wavelets as a tool for the statistical characterization of variability

open access: yes, 2011
In the field of gamma-ray astronomy, irregular and noisy datasets make difficult the characterization of light-curve features in terms of statistical significance while properly accounting for trial factors associated with the search for variability at ...

Higher Order Haar Wavelet Method for Solving Differential Equations

open access: yes, 2021
The study is focused on the development, adaption and evaluation of the higher order Haar wavelet method (HOHWM) for solving differential equations. Accuracy and computational complexity are two measurable key characteristics of any numerical method. The HOHWM introduced recently by authors as an improvement of the widely used Haar wavelet method (HWM)
