    Keywords: social tension, monitoring, accommodation cost in the hostel, the educational organization, the higher education

  • Stratification of the lubricant in the thrust bearings

    In this paper, based on a system of equations of motion of a viscous incompressible fluid with the viscosity depending on the pressure, and continuity equations, provides self-similar solution using the current functions of the stratified flow of lubricant in the thrust bearings. The proposed model is calculated in contrast with the existing three-layer stratification, further complicated by the dependence of the viscosity of the lubricant pressure. An analytical expression allows to obtain a description of three-layer stratified fluid lubricants and a graph of the effect of structural parameter and viscosity ratio stratified layers on the basic performance of the bearing. Numerical analysis of the dependence of the parameters of the adapted profile and load-carrying capacity of lubricating layers.

    Keywords: three-layer lubrication, maintenance power circuit adapted slider, stratified flow, pressure dependence of viscosity.

  • Environmental, economic and social efficiency of resource use in world space scale

    The article is devoted to the solution of problems of effective and safe management in the global scale of the space as a whole and in individual territories. The relationship of economic and environmental security of the world community can be characterized as socio-ecological and economic security, which characterizes the steady state of progressive development of society based on sustainable use and protection of natural resources as a basis for her life under the destructive influence of various external and internal factors. In addition, because the processes associated with security, in essence, are the management, we also need the presence of the subject, ensuring safety,which is considered the productive sector of the economy of each state. The purpose of eco-economic system of environmental management in the global community is the environment in the development of mutually beneficial political and economic relations between .

  • Multiple-factor model of measurement of labor productivity

    The analysis and systematization of methods of an assessment of multiple-factor labor productivity is carried out; the multiple-factor model of measurement of labor productivity in spheres of material and non-material production in system of regional reproduction proportions is constructed.

    Keywords: productivity, productivity, labor, model, reproduction, region

  • Effective contracts with scientific and pedagogical employees: domestic experience

    The analysis of standard and legal documents of Russia is carried out to the fields of education and sciences which revealed need of development of a scientific component for activity of universities. The received results formed the basis of promotion of a hypothesis that "the effective contract" can act as one of instruments of achievement of the priority purposes and tasks of university, including on their entry into world ratings

    Keywords: effective contract, productivity, university, salary, efficiency indicators

  • Employment of the population as factor of economic development of the territory

    One of the main priority objectives of economic policy of the government of any country in the long term is stimulation of economic growth. Has labor productivity direct impact on rates of economic growth both in the country in general, and in separate branches of economy. Employment can be referred to one of important factors of growth of labor productivity undoubtedly. In article the problem of employment of the population as one of factors of growth of labor productivity and its influence on the economic growth of the territory is considered. The correlation and regression analysis between indicators of unemployment rate and gross domestic product (GDP) is carried out. As a result of the analysis of coefficient of linear pair correlation we come to a conclusion that, according to Cheddok's scale, qualitatively communication force between factors can be characterized as "moderate", that is in 28,64% change of unemployment leads to change of GDP. If to analyze coefficient of linear pair correlation, we can come to a conclusion that communication between factors the return, that is at decrease in unemployment is observed GDP growth and vice versa. Thus, labor productivity, one of which factors is employment of the population, is the most important indicator of development of economy of the territory.

    Keywords: Employment of the population, economic development of the territory, labor productivity, correlation and regression analysis.

  • Forecasting model of the dynamics of reproduction ratios at the regional level: a cognitive approach

    Based on the identification of structural and functional characteristics of the performance and productivity of work, taking into account the balanced development of the region reproduction proportions, constructed cognitive map interaction of regional reproduction proportions with the external environment. In the research was carried out expert assessment of the direction of influence factors in the cognitive model predicting the dynamics of reproduction proportions of the region, on the basis of what has been built cognitive simulation model for predicting the dynamics of reproduction proportions region.

  • Development of Autonomous Underwater Vehicle Simulator

    Testing and debugging of real equipment is a time consuming task. In particular, in the case of marine robots, it is necessary each time to carry out the transportation and deployment of a robot on the water. Experiments with not yet fully functional prototype of marine robot equipped with expensive hardware is in the meantime very risky. Therefore, the use of simulators is affordable way to accelerate the development of robotic systems from the viewpoint of labor effort and cost of experiments. This paper presents a simulator specifically designed for autonomous unmanned underwater vehicles.
