The Use of a Genetic Algorithm in Modeling the Electrophysical Properties of a Layered Nanocomposite

Authors: Kim R. P., Romanchuk S. P., Terin D. V., Korchagin S. A.

The research proposes an approach to solving the problem of selecting layered nanocomposite components with given electrical properties. The known methods for modeling the nanocomposites electrical characteristics are based on a preliminary analysis of such characteristics as the dielectric constant and electrical conductivity of the materials that make up a nanocomposite. The study proposes an algorithm for the selection of components of a layered nanocomposite using a genetic algorithm.

Graph approach for finite-element based model of an elastic body under conditions of axisymmetric deformation

Authors: Tirimov A. A.

 A numerical method for analysis of the stress – strain state of elastic media based on a discrete model in form of directed graph is suggested. To analyze a deformable body using the graph approach, we partitione a solid body on elements and replace each element by its model in the form of an elementary cell. The matrices, presenting several structure elements of the graph, and the equations, describing the elementary cells, contribute to deriving the constitutive equations of the intact body.

Parallel Algorithm of Optimal Parameters Calculation for the Single Channel Angular Stabilization System

Authors: Andreichenko D. K., Andreichenko K. P., Kononov V. V.

On the instance of mathematical modeling of an independant angular stabilization system of rocket missiles of a volley fire developed a parallel algorithm for parametric synthesis, which allows to reduce the response time and stabilization errors of the operated combined dynamic systems, for which some design parameters change continuously in a fixed range.
