Note on the Solution of Transport Equation by Tau Method and Walsh Functions [PDF]
Abstract and Applied Analysis, 2010 We consider the combined Walsh function for the three-dimensional case. A method for the solution of the neutron transport equation in three-dimensional case by using the Walsh function, Chebyshev polynomials, and the Legendre polynomials are considered.

Nonseparable Walsh-type functions on Rd [PDF]
Glasnik Matematicki, 2004 We study wavelet packets in the setting of a multiresolution analysis of L2() generated by an arbitrary dilation matrix A satisfying |det A| = 2. In particular, we consider the wavelet packets associated with a multiresolution analysis with a scaling ...

Investigation of wave processes and rhythmic activity of the human brain using the Walsh orthogonal function system [PDF]
Известия высших учебных заведений: Прикладная нелинейная динамикаThe purpose of this work is to study the wave processes and rhythmic activity of the brain based on multiscale parametric maps of electroencephalograms obtained as a result of algorithmic application of a system of discrete functions. Methods.

Unsteady Solution of Non-Linear Differential Equations Using Walsh Function Series [PDF]
, 2015 Walsh functions form an orthonormal basis set consisting of square waves. The discontinuous nature of square waves make the system well suited for representing functions with discontinuities.

On the order of magnitude of Walsh-Fourier transform [PDF]
Mathematica Bohemica, 2020 For a Lebesgue integrable complex-valued function $f$ defined on $\mathbb R^+:=[0,\infty)$ let $\hat f$ be its Walsh-Fourier transform. The Riemann-Lebesgue lemma says that $\hat f(y)\to0$ as $y\to\infty$.

Discovering Non-Linear Boolean Functions by Evolving Walsh Transforms with Genetic Programming
Algorithms, 2023 Stream ciphers usually rely on highly secure Boolean functions to ensure safe communication within unsafe channels. However, discovering secure Boolean functions is a non-trivial optimization problem that has been addressed by many optimization ...
