Release: 2016-2 (14)
Keywords: theory of active systems, modeling, mathematical models of social and economic processes, trade-commerce network
Annotation: In this work the question of modeling of stream processes between participants in trade-commerce systems is considered. The model of the description processes of an ex-change between economic agents of a network in the local markets taking into account factors of supply and demand is developed
Research of process of insurance payments with limited insurance coverage
Page:303-308
Release: 2016-2 (14)
Keywords: mathematical model, insurance company, insurance payments, queueing system, characteristic function
Annotation: This paper is devoted to the research of the model of insurance company with a limited insur-ance coverage in the form of queuеing system with an unlimited number of servers. Using method of characteristic functions we got two-dimensional probability distribution of a number of risks that are insured in the company and a number of demands for insurance payment
Detemination of the characteristic time of a binary mixture separation in a cylindrical thermogravitational column
Page:320-324
Release: 2016-2 (14)
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
