Infinite Sets of Related b-wARH Pairs
Let b greater then or equal to 2 be a numeration base. A b-weak additive Ramanujan-Hardy (or b-wARH) number N is a non-negative integer for which there exists at least one non-negative integer A, such that the sum of A and the sum of base b digits of N, added to the reversal of the sum, give N. We s....

A Minimality of the Rational Canonical Form
The rational canonical form theorem is very essential basic result of matrix theory, which has been proved by different methods in the literature. In this note, we provide an efficient direct proof, from which the minimality for the decomposition of the rational canonical form can be found.....

The Study of the Movement of Cotton Particles and Mathematical Modeling of the Impact of It at the Ginning Point
This article studied the principles of movements in the horizontal part of the newly constructed ginning camera, which is created by the authors, of the cotton particles. During the movement, the cotton particles get affected by pressing to various surface and forceful turbulent and horizontal movem....

Space--Time Spectral Collocation Method for Solving Burgers Equations with the Convergence Analysis
This article deals with a numerical approach based on the symmetric space-time Chebyshev spectral collocation method for solving different types of Burgers equations with Dirichlet boundary conditions. In this method, the variables of the equation are first approximated by interpolating polynomials ....

Flow and Heat Transfer of Basalt Melt in the Feeder of the Smelter Furnace
The flow and heat transfer of the basalt melt in the boundary layer on a flat plate is considered. The conditions of formation of the layer and the intensity of heat transfer are determined. A self-similar analysis using the symmetry method was used. A system of ordinary differential equations in se....
