Keywords: multicomponent mixture, heat and mass transfer, diffusion, thermal diffusion, thermogravitational column, unsteady-state problem, characteristic time
Annotation: In this paper, the unsteady-state binary mixture separation in a cylindrical thermogravitational column is considered. For this process, the dependence of the characteristic time of establishing the steady-state separation on the ratio of the cylinders radii is obtained. When the ratio is close to unity, the characteristic time corresponds to that of a flat-plate column
Simulation of dynamics of multiparticle systems for kinetic model consideration
Page:324-330
Release: 2016-2 (14)
Keywords: Monte Carlo method, pair interactions, vehicular traffic flow, coagulation equation, price formation
Annotation: We consider four problems, three of which are not related to rarefied gas dynamics, but are described by the Boltzmann type equations. To solve these problems, we propose to use the integral equation of the second kind approach and the weight simulation of Markov chain, the latter is uniquely determined by the coefficients of the integral equations
On right-primitivity conjecture for finite semifield
Page:330-336
Release: 2016-2 (14)
Keywords: semifield, spectrum of semifield, left-primitivity, automorphism
Annotation: The author consider the algebraic properties of the semifield of order 64 that is one of two known counter-examples to G. Wene conjecture of left-primitivity for any finite semifield. The subfileds, automorphisms and spectrum are described. It is proved that the multiplicative loop of non-zero elements of this semifield is singly-generated

Linear inverse problem for the pseudo hyperbolic equations
Page:343-351
Release: 2016-2 (14)
Keywords: inverse problem of pseudo hyperbolic equation, Volterra equation, conditions override
Annotation: In this paper linear inverse problems for pseudo hyperbolic equations is considered. We prove the corresponding theorem on the unique solvability of the inverse problem
