Аннотация: This article is devoted to the study of the rational use of the resource potential of the territories of the Republic of Kazakhstan on the basis of the coefficient of concentration orlocalization of production. The developed mathematical model takes into account many factors affecting the anisotropy of the country's economic space development, and allows us to propose an optimal strategy for managing regions. In the work using a cluster model based on hierarchical algorithms, graphs-dendrograms are constructed and regions are classified according to their level of competitiveness.

3D aerodynamic analysis of awing with 2- way fluid-structure interaction. [Текст] / O. Sayakov // News of national academy of sciences of the republic of Kazakhstan. . - 2021. - №4. - P. 129-134

NACA 23012 airfoil -- Fluid-Structure Interaction -- ANSYS -- strongly coupling study -- deformation of the wing
Аннотация: the aircraft wings facing different weather conditions start to deform and oscillate with an unpredictable velocity and amplitude. Most of the previous studies were conducted assuming the wing as a rigid body.However, the wing analysis with Fluid-Structure Interaction(FSI)has significant effectson the results. This paper compares the strongly coupled 2-way FSI analysisof the flexible wing with a geometry of NACA 23012and a rigid body 2D winganalysis. Both studies were carried out at a Mach number of 0.075 and Reynolds number of 0.6×106for different angles of attack.Moreover, the analysis of the wing deformation at the start of the flight is also presented. Finally, it was shownthat FSI analysis gives closer results to the experimental measurements, proving the worthiness of the extra efforts of the two-way FSI analysis
