INTERPOLATING WAVELETS ON THE SPHERE

open access: yesUral Mathematical Journal, 2019
There are several works where bases of wavelets on the sphere (mainly orthogonal and wavelet-like bases) were constructed. In all such constructions, the authors seek to preserve the most important properties of classical wavelets including constructions

Experimental demonstrations of unconditional security in a purely classical regime

open access: yesScientific Reports, 2021
So far, unconditional security in key distribution processes has been confined to quantum key distribution (QKD) protocols based on the no-cloning theorem of nonorthogonal bases.

Weighted complex projective 2-designs from bases: optimal state determination by orthogonal measurements [PDF]

open access: yes, 2007
We introduce the problem of constructing weighted complex projective 2-designs from the union of a family of orthonormal bases. If the weight remains constant across elements of the same basis, then such designs can be interpreted as generalizations of ...

Numeric-analytical approach to integrals calculation at construction of orthogonal models

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2009
The numeric-analytical method of calculation of the integrals is proposed for construction of orthogonal models. The given method allows to increase the accuracy of orthogonal models due to obtained algebraic and recurrent relations for integrals used ...

Dynamic Modelling and Optimal Control of a Rotor of Active Magnetic Bearings [PDF]

open access: yesInternational Journal of Industrial Electronics, Control and Optimization, 2019
Active magnetic bearings (AMBs) are relatively new members in bearings family. Against other bearings which support loads by forces produced by fluid film pressure or physical contact, AMBs support loads by magnetic fields without any contact with the ...

3D shape reconstruction with a multiple-constraint estimation approach

open access: yesFrontiers in Neuroscience, 2023
In this study, a multiple-constraint estimation algorithm is presented to estimate the 3D shape of a 2D image sequence. Given the training data, a sparse representation model with an elastic net, i.e., l1−norm and l2−norm constraints, is devised to ...

Analysis of High-order Approximations by Spectral Interpolation Applied to One- and Two-dimensional Finite Element Method [PDF]

open access: yesJournal of Applied and Computational Mechanics, 2020
The implementation of high-order (spectral) approximations associated with FEM is an approach to overcome the difficulties encountered in the numerical analysis of complex problems.

Application of the Algebraic Extension Method to the Construction of Orthogonal Bases for Partial Digital Convolutions

open access: yesAlgorithms
Mathematical tools have been developed that are analogous to the tool that allows one to reduce the description of linear systems in terms of convolution operations to a description in terms of amplitude-frequency characteristics.

Orthogonal multiplet bases in SU(Nc) color space

open access: yes, 2012
We develop a general recipe for constructing orthogonal bases for the calculation of color structures appearing in QCD for any number of partons and arbitrary Nc.
