Release: 2016-2 (14)
Keywords: database, comprehensive ecological monitoring, reservoir
Annotation: Conceptual and relational schemes of data-base to store spatial temporal facts about Krasno-yarsk reservoir ecology are represented in the paper. Represented results allow to integrate collected data into informational space for inferring comprehensive analytical model of arti-ficial reservoir behavior
On formalization of the transition rules in pedestrian dynamics model SIgMA.CA
Page:293-300
Release: 2016-2 (14)
Keywords: pedestrian dynamics model, cellular automata, transition rules, movement strategies
Annotation: Transition rules for a pedestrian dynamics model based on cellular automata are presented. Methods of implementation of a patient man strategy, conflict resolution are proposed
Modelling of the exchange processes in trade systems
Page:300-303
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
