Approximate interpolation by functions in a Haar space

Journal of Approximation Theory, 1989
Let \(\{\phi_ 1,...,\phi_ n\}\) be a Chebyshev system in C(I), where I is a proper compact interval in R. In J. Approximation Theory 32, 257-270 (1981; Zbl 0472.41024)] the author proved that interpolation process can be performed approximately, with error at most \(\epsilon\), on a set of \(n+1\) distinct points of I, provided that set is sufficiently

3D Inversion of Magnetic Data through Wavelet based Regularization Method [PDF]

International Journal of Mining and Geo-Engineering, 2015
This study deals with the 3D recovering of magnetic susceptibility model by incorporating the sparsity-based constraints in the inversion algorithm. For this purpose, the area under prospect was divided into a large number of rectangular prisms in a mesh

Nonlinear analysis of operator electroencephalograms subjected by electromagnetic noise radiation

Доклады Белорусского государственного университета информатики и радиоэлектроники, 2019
The experimental investigation of operator electroencephalograms subjected by electromagnetic noise radiation is described. Using the nonlinear methods (Higuchi method and Wolf method) with the preliminary noise suppression by the wavelet transformation ...

Haar wavelet Arctic Puffin optimization method (HWAPOM): Application to logistic models with fractal-fractional Caputo-Fabrizio operator

Partial Differential Equations in Applied Mathematics
This study introduces a novel hybrid numerical methodology for approximating differential equations involving the fractal-fractional Caputo-Fabrizio (FFCF) operator, which is an essential tool for modelling complex dynamical systems involving memory ...

The Relative Prevalence of Wave Packets and Coherent Structures in the Inertial and Kinetic Ranges of Turbulence as Seen by Solar Orbiter

The Astrophysical Journal
The Solar Orbiter (SO) mission provides the opportunity to study the evolution of solar wind turbulence. We use SO observations of nine extended intervals of homogeneous turbulence to determine when turbulent magnetic field fluctuations may be ...

Pseudorandom Function-like States from Common Haar Unitary

Recent active studies have demonstrated that cryptography without one-way functions (OWFs) could be possible in the quantum world. Many fundamental primitives that are natural quantum analogs of OWFs or pseudorandom generators (PRGs) have been introduced, and their mutual relations and applications have been studied.

Weak solutions of functional differential inequalities with first-order partial derivatives

Journal of Inequalities and Applications, 2011
The article deals with functional differential inequalities generated by the Cauchy problem for nonlinear first-order partial functional differential equations. The unknown function is the functional variable in equation and inequalities, and the partial
