Аннотация: Every year, the atmosphere in Kazakhstan is polluted approximately 5-7 million tons of pollutants,about a third of which belong to the vehicle. Also excess pollution of the air basin of the cities ofthe Republic is caused by pollution of pollutants by metallurgy, oil refining and chemical industryfactories, automobile and railway transport. The harmful substances emitted by motor transportadversely affect the air, water reservoirs, soil and the planet’s biosphere. At Nowadays car engineconsumes about 3 kilogram of atmospheric oxygen when liters of gasoline per 1 kg are burned.Every car delivers 60 m3of gas per hour, and the truck produces 120 m3of gas. These substancesare very dangerous for living organisms and finding solution for the problem of cleaning exhaustedgases is very actual.The purpose of this article is mathematical and numerical modeling on transfer processes in motor-car neutralizer with usage modern programming language and modern computing technologies.The solution of such a problem brings a certain contribution to the protection of the environmentfrom automobile exhaust gases. The task of cleaning at exhaust gases is investigated, that is tosay catalytic oxidation of exhausted gases automobile neutralizer . The mathematical model thereis a system of differential equations warm and mass transfer including heat generation from thechemical reaction. The equation system is solved through numerical methods and to create anddevelop an algorithm of computing the task of cleaning exhaust gases in automobile neutralizer.

Аннотация: This paper is part of the research on creating semantic analysis models in web resources for definingan extremist orientation in the text. To solve this task a model was created, which consists of fivestages: identifying websites of an extremist groups, preparing for data extraction, data extraction,data analysis and classification. This work presents the results of data analysis stage of abovementioned model. The purpose of this study is to identify keywords, often used by extremists,which will later be used to classify texts to "extremist" and "neutral" categories using machinelearning methods. There is no such database for the Kazakh language. As the result of this studyan experimental corpus and list of keywords in Kazakh language was created. The keywords wereadded to the database with various morphological variants. The program was built that checksfor the presence of extremist keywords in the given input text and displays the words found.

Аннотация: This work is devoted to the study of centrifugation processes, which are one of the most complexprocesses of technology. The use of the action of the centrifugal force field for the separationof heterogeneous liquid systems in a rotor system (centrifuge) is very effective. Separability ofcentrifuged materials, multiphase dispersion, the relationship between phases cause ambiguousprocesses of centrifugation, and therefore it is not always possible to accurately predict and evaluatethe main characteristics of the separation of heterogeneous systems in the centrifugal force field.For a qualitative assessment of the main separation characteristics, such as the angular velocityof rotation, the dependence of the angles of inclination of the glasses on the angular velocity, thesettling time of particles, etc., is created a mathematical model of the vertical rotor system. Therotor represents a round disk on which cups (vial) with a multiphase liquid are symmetricallysuspended. A particular case of a fixed rotor is considered. Nonlinear differential equations ofmotion of the suspension particle, which have no exact solution, are obtained. The research isconducted by analytical and numerical methods. The dependence of the slope angles of the tubesfrom the angular rotational speed of the rotor, sedimentation curves are obtained , which allowestimating the time of particle deposition and the effect of the particle size distribution on theseparation process. The results of this research work allow us to determine with sufficient accuracyall the necessary characteristics of the sedimentation working process, and also, in certain cases,it is possible to exclude the conduct of experimental work. The results of the work confirm thephysical meaning of the process, which can serve as a justification for the use and introduction ofthis mathematical model in industrial production.

Аннотация: The links of high-speed mechanisms and manipulators are deformed under the action of inertiaforces and external loads. These deformations have significantly influence on the accuracy of execu-tion of the required law of motion by the operating point of the mechanism and the positioning ofthe manipulator grip. Accordingly, longitudinal and transverse displacements, angles of rotation ofcross-sections of links under the action of distributed dynamic and external loads are investigatedin this paper. The developed technique allows defining deformations of links of mechanisms andmanipulators and can be applied at their designing. To determine the transverse displacements,the angles of rotation of the cross-sections of the links – the basic differential equation of the elasticline of the beam, to determine the longitudinal displacements of the points of the links – Hooke’slaw and the boundary conditions of the computed scheme of the investigated linkages for elasticcomputation are used. The bending moment in the basic differential equation of the elastic line ofthe beam and the longitudinal force in Hooke’s law were determined by the theory developed bythe authors of the analytical definition of internal forces in the links of planar linkages with stat-ically determinate structures, taking into account the distributed dynamic loads from the massesof links, dead weight and from the acting external loads. According to the developed technique,programs are created in the MAPLE system and animations of the movement of mechanisms arereceived, with the construction on the links the diagrams of transverse, longitudinal displacementsand angles of rotation of the link cross-sections. The developed analytical technique for determin-ing deformations in the cross-sections of links is used to calculate the strength and stiffness ofelements of movable linkages.

Аннотация: Adaptive generation of computational grids can improve the efficiency of mathematical model-ing by increasing the accuracy of numerical approximations. The paper describes a method forconstructing unstructured grids with adaptation based on differential methods. The applicationof these methods ensures a smooth distribution of the geometric characteristics of the grid, i.e.the appearance of adjacent cells that differ greatly in size and shape becomes unlikely. To achieveproper adaptation in unstructured grids we use the novel approach based on methodology of adap-tive structured grid construction. This approach uses the method of grid construction based onsolving inverted Beltrami equation to create mapping of some sample grid domain to the physicalarea. This mapping is used to construct point set on which the unstructured grid is constructedusing Delaunay triangulation method. Thus, the result is unstructured grid with proper adapta-tion. Adding fault and fractures or other structure elements may be supported by implementingconstrained Delaunay triangulation.

Аннотация: The article considers the concept with lslamic finance and airlines .Aviation companies in Muslim countries actively use lslamic banking. The paradigm of lslamic Economics and Finance is based on financing the real sector of the economy and transactions with real assets that already exist at the time of conclusion of the contract, as well as the absence of uncertainty and loan interest .Therefore, if the share of lslamic financial transactions in the market increases, there will be fewer speculative transactions and more contracts that create real value for the economy.
