The work is devoted to the comparison of two methods of symbolic regression, a method of genetic programming and a variational method of genetic programming. The comparison is made on the basis of the computing experiment, which solved a problem of control system synthesis for a model of nonlinear control object, describing the interaction of the two systems of "predator" and "victim". For the purity of the experiment the genetic algorithms parameters in the both methods were Identical. For variational genetic programming there was selected a trivial basic solution in the form of the sum of input variable products for custom settings. This basic solution is always chosen in the case of the absence of meaningful task analysis. The comparison of methods for the speed of solving the problem and for the quality of the achieved control is made. © 2017 The Authors.

Considered a problem for the relative equilibrium stabilization of the orbital station at the unstable collinear libration point L2 in the Earth-Moon system with a small change of the reaction engine acceleration (constant in magnitude) rigidly attached to the station. It is shown, that with a small movement of the station's center of mass relatively to the point L2 in the station's parameter space there is a region in which its relative equilibrium in its translation-rotation motion is stable in the first approximation. © 2015 IEEE.

The paper describes the mechanism of changes in wall ceramics physical-mechanical properties and structure when additives of various types and quantities are doped. The authors come to the conclusion that composite modifications of ceramic mixtures improve their molding properties, reduce the firing temperature for 150-20007deg;C and increase resistibility and frost resistance of end products. These composition additives consist of crushed glass fine powder mixed with oil sludge in 1/5 proportion. The paper proves that these composition additives 30-35% reduce energy consumption in wall ceramics production and provides wall ceramics of high quality for civil and industrial engineering. © 2015 The Authors.

Hydroalkoxycarbonylation of olefins with carbon monoxide and alcohols under condition of homogeneous - catalysis with transition metal complexes allows facile one-step synthesis of practically useful carbon acid esters. Many of them have biological activity and are constituents of drugs or valuable intermediate products in drug synthesis. Hydroalkoxycarbonylation of isobutylene with carbon monoxide and alcohols in the presence of catalytic system Pd(PPh3)4-PPh3-TsOH was applied for preparing of biological active isovaleric acid esters: 1-menthylisovalerate (main active component of the spasmolytic medicine “Validolum”), ethylisovalerate (intermediate product for obtaining sedative and spasmolytic medicines “Ethyl ester of α-bromisovaleric acid” and “Corvalolum”), cyclohexylisovalerate (bactericide activity) and benzylisovalerate (bactericide and antifungus activity). Hydroalkoxycarbonylation reaction of isobutylene with carbon monoxide and alcohols (ethanol, cyclohexanol, l-menthol, benzyl alcohol) in the presence Pd(PPh3)4-PPh3-TsOH system carried out at conditions: temperature 100 ºC; CO pressure 2.0 MPa; reaction time 4 h; reactants and catalyst components ratio [alcohol]:[isobutylene]:[Pd(PPh3)4]:[PPh3]:[TsOH] = 435:550:1:3:12. The yields of the products were 71-95% (on converted alcohols). The selectivity in linear reaction products was 100%. Such a high regioselectivity is apparently provided both by the structure of the starting alkene (isobutylene) and by the reaction mechanism. The most probable is a hydride mechanism. Due to the more advanced technology of production the Medicines will have better qualitative characteristics. The cost of production of the Medicines with the use of new technologies is 2-3 times lower as compared to the medicines produced by existing at the present traditional technologies. © 2014 Al-Farabi Kazakh National University.

Agriculture is one of the main industries of Kazakhstan, especially in the Kyzylorda Region. Before the reforms, agriculture in this region was better developed than the manufacturing industry; this is no longer the case. The main crop grown on the irrigated land of the region is rice. Inefficient distribution of cultivated areas, their excessive use, and the growing volume of fertilizers used in the soil increases the salinization of the soil on arable land. This necessitates the investigation of the soil on irrigated land through environmental and geographical monitoring. This research analyzes the current reclamation state of irrigated cultivated land in the Kyzylorda Region located in the Kazakhstani part of the Eastern Aral Sea region, in the lower reaches of the Syr Darya River. The causes and level of soil salinization in said areas were determined. In addition, the factors that affect land salinization in the Shieli-Zhanakorgan, Kyzylorda, and Kazaly-Aral irrigation sectors were determined. The research classifies the arable land in the Shieli, Zhalagash, Karmakshy, Kazaly, and Aral Districts in terms of salinization type, characterizes its peculiarities, and investigates ways of improving the salt regime of soil on irrigated arable land. © 2016 Toktaganova & Karlikhanov.

The Aral Sea (an intracontinental saline lake in western Central Asia) is of great interest because of its rapid shrinkage during the last 50. years, which caused catastrophic environmental and socio-economic consequences for the region and its population. Geoscientists established the existence of similar multiple fast and deep lake level fluctuations in the past; however, a comprehensive picture of these changes has been lacking. In this paper, we summarize published and new geomorphological, sedimentological, paleoenvironmental, geoarcheological, and historical data to reconstruct fluctuations in the Aral during the last two thousand years. Two deep regressions are recognized, in addition to the modern human-induced regression. The regressions occurred at ca. 2.1-1.3 and 1.1-0.35. ka. cal BP according to the sedimentary and faunal data, and 2.1-1.45 and 1.0 (0.85)-0.45. ka. cal BP according to the archeological and historical data. The Aral Sea lake level dropped to ca. 10. m. a.s.l. during the first regression and to ca. 29. m. a.s.l. during the second one. Transgressions which separated these periods reached elevations of ca. 52. m. a.s.l., and 54. m. a.s.l., respectively. According to the current data, the regressions lasted longer than the transgressions, or were of equal duration. Reasons considered for past Aral Sea lake level changes include both natural and human-related causes, as the region features more than 2000. years of agricultural activity. © 2014 International Association for Gondwana Research.

Studied the photogravitational restricted circular three-body problem in which both main gravitating body is radiating. Conducted a complete investigation of the nonlinear stability of the triangular libration points and built their stability areas in the configuration and parameter spaces. For these points in the stability area in the first approximation, except for a set of points corresponding to the resonances of 3rd and 4th orders, almost everywhere there is stability for the majority of initial conditions(in the Lebesgue measure) and formal stability. Shown that for all resonances of order 3 the investigated points are unstable. © 2016 IEEE.

This article is devoted to the problem of linguoculturological aspect of studying bilingualism. We give an overview of scientific works dedicated to the linguoculturological aspect of studying bilingualism. The author reveals the essence of such terms as "ethnolinguistics", bilingualism and multilingualism. The article describes the main stages of the bilingualism study. It also provides the basic methodological attitudes of the linguoculturological analysis. We provide a definition of Cultural Linguistics, define its mission, the object and subject of study. The author refers to the basic terms of Cultural Linguistics. One of the pressing issues of Cultural Linguistics, in his opinion, is a common matalanguage design for both the language and the culture. In this article the author focused on the ways of interaction between the language and the culture of two languages, entered into the cultural and language contact.
