The paper deals with a new mathematical formulation of the problem of determining the parameters of cylindrical surfaces on the results of their measurements on coordinate measuring machines. Minimization function is supplemented by deviations of derived parameters from their nominal values, so the problem becomes well-conditioned for measurement of cylindrical surfaces in small areas.

The article presents the results of analytical study of mechanics of formation of cylindrical holes in solid material by a rotating tool. The analysis is performed by the energy method using the extreme positions of deformation mechanics at following assumptions. The processed material is considered isotropic, having strain hardening, that corresponds to the conditions of full cold deformation. In addition, it is assumed that the contact friction submits to the Coulomb law, that is proportional to the normal pressure at the contact, the hardening curve on a dedicated section approximated by a linear function. Two variants of cutting are investigated: the tool with the drill web, that has a negative rake, and the tool with the corrected drill web. It is shown that the traditional drill with a drill web is not an effective tool. Optimization of geometry of a drill web provides repeated reduction of axial force. The physical equations for calculation of power parameters of drilling based on the actual geometry of a cutting part of the tool, and also its central part named a drill web, are given.

Based on the behavior of structural materials under cyclic elastic-plastic deformation and low cycle fatigue life assessment the authors established a system of mathematical modeling of cyclic loading of structures using finite elements. The paper considers the examples of solutions of test problems and real structures.

The paper deals with the institute of contemporary Russian political consultants. The authors examined types of political consulting and proposed their own classification of political consultants in Russia. The special relevance of the work lies in the fact that the authors analyzed the problem through the prism of poorly studied phenomenon of political consumerism.

Russia is part of a geopolitical system, and the transformation within the country are closely linked to external changes, which have a strong influence on an economic policy. The article presents an analysis of the factors getting an obvious trend in the distribution of the world community and an impact on the possibility of conceptual change in our country.

The article considers intangible actives of the organization as competitive advantages in the conditions of postindustrial development.

The paper presents an analysis of some factors affecting the competitiveness of the Russian automotive industry sector. The basic development strategy of the automotive industry in Russia, the main directions of state policy in shaping the domestic car market with foreign partners, foreign investment and innovation. One reason for the low competitiveness of Russian car is problems in engineering education, the low level of funding and setting priorities of research and development activities.

The article is devoted to loanwords and their role in the modern Russian language. The author discussed the new trends connected with their using, origin and the most popular groups of Americanisms in Russian language.

This article offers a brief analysis of the current state of the Russian automotive and road networks, interconnection of its facilities with roadside infrastructure, the exposed factors influencing the future development of roadside service.

The present article deals with pass tests for determining the level of student physical preparedness and of physical skill development. A variety of application options during different periods of education or training stimulates students to improve the state of their physical activity.

Since 2011 in MSTU МАМИ on Technology of Construction Materials department the two new directions of tutoring are opened: 150100 Pedagogical education, qualification - the bachelor of technological formation and 220600.62 Innovations, qualification - the bachelor of engineering and technique. Both directions should fit industry necessity of the highly-skilled personnel, capable to work on junctions of specialities: engineer - teacher and the engineer - the manager. Thus the area of employment of the graduate of university essentially extends. The bachelor of technological formation owning both design-engineering, and pedagogical knowledge by skills and abilities can work not only as a teacher in educational institutions of initial average and higher vocational training, but also the process engineer or the organizer of manufacture on state and in the private engineering operations. The bachelor of engineering and technology with both design-engineering, and management-economic knowledge skills and abilities can execute not only functions of the process engineer on manufacture, but also to participate in working out of investment projects of innovative engineering of the operations and architectures of the state and private sphere.

The authors discuss the language training for foreign nationals studying programs of higher education. Defined and justified objectives of teaching Russian as a foreign language, the volume of workload. The presented material highlights the problems encountered in teaching Russian as a foreign language in the format of the educational standards. Are the requirements for the standards and the State levels of proficiency, uncovered their contradictions. Marked by the paradox of testing, confirmed the above examples. Confirmed the postulate that the exam - not just an instrument of control, but also an incentive to learning the material, which means that one way to improve the quality of education.
