  • Numerical study of the heat sink with a change in the aggregate state of the working substance

    In the article, a numerical study of the heat sink with a change in the aggregate state of the oil is carried out. Simulation was carried out in Ansys Fluent CAD for two modes, static - with constant heating of the oil at 340K and dynamic, at which the heating temperature varied with time from 340K to 270K. Heat transfer in the event of a change in the aggregate state of a substance is widely used in cases where it is necessary to achieve the maximum efficiency of heat exchange. In this case, the energy is expended on the phase transition of the substance, for example, to evaporation from the liquid phase. The advantage of the heat-sink design described in this work is a rather high rate of heat transfer, greater resistance to various influences, including mechanical ones, which is primarily ensured by the simplicity of construction, eliminating the drawbacks of classical designs, which are cumbersome (the presence of an external cooling circuit ) and the limited rate of heat transfer.

  • Reducing the financial risks of a construction company by means of the diversification economic activity

    Each managing subject tries to lower level of risk factors for himself for the purpose of increase of efficiency of activity. One of options of minimization of losses and decrease in action of risk factors is the diversification consisting of distribution of means between various activities so that losses just seeing activity can be compensated by profit on other kind of activity of the managing subject.
    In article the diversification of economic activity connected with use by construction company of new production and marketing capabilities for the purpose of increase of efficiency of economic activity is considered.
    The decision on diversification as a way of decrease in risk of activity of the enterprise is accepted on the basis of correlation coefficient which shows degree of expressiveness of a tendency to changes of size of one variable at changes another. At value of coefficient of the correlation, equal to zero, lack of communication between variables is observed. If numerical value of coefficient of correlation is equal to unit, variables are connected by direct functional link, that is there are unidirectional changes of variables. At value of coefficient of the correlation, equal the minus to unit, between variables is observed the return functional communication testifying to a raznonapravlennost of change of variables. At value of coefficient of the correlation, equal or close a minus to unit, it is expedient to make the decision on carrying out diversification.
    The reasonable model of optimization of a choice of the customer is offered mathematically.

  • About the corporation questions

    The article explores the main types of organization of the corporation and management in Russia. The corporation is defined as a special organizational and economic form of business. There we identified problems, specific, prospects for the formation and development. It was investigated the features and structure of corporations , as a result of its membership of the integration processes . It was measured the economic and financial management aspects, which may be useful in the development and investment attractiveness of the corporation. The Corporation is a more complex business structure. Corporations  have certain rights, privileges, and liabilities beyond those of an individual. Doing business as a corporation may yield tax or financial benefits, but these can be offset by other considerations, such as increased licensing fees or decreased personal control. Corporations may be formed for profit or nonprofit purposes. The author gives the aspects of each formation.

  • Unsteady computational model inhomogeneous two-layer porous bearing of finite length when combined feed lubrication

    In this paper, based on Darcy equations that govern the lubricant in porous layers , and the modified Reynolds equation in the framework of a short bearing solve the problem of unsteady motion of a viscous incompressible lubricant in the bearing clearance double-layer porous . Here we consider the case when the permeability in porous layers in the axial direction is changed by the normal law , and the combined feed lubrication is performed simultaneously in the axial and perpendicular to the bearing axis directions. As a result, the pressure field found in porous layers and in the lubricating layer and analytical dependences for the efforts of the oil film . Compiled by the equation of motion tongue and solved the problem of the stability of the unsteady motion of a pin bearing , found that in the case of a combined bearing lubrication working more steadily compared with the cases or axial directions perpendicular to the axis lubrication . The results obtained can be offered for the development of cylindrical dampers with double-layer porous collar , effectively attenuating transmitted force imbalance in the combined feed lubrication.

  • Complementarily - Adaptive use tools of intergovernmental relations for the purpose of leveling the socio-economic development of regions

    The current system of intergovernmental fiscal relations , the trends of its development in Russia , including the alignment process , aimed at smoothing the territorial differentiation of socio- economic development of regions. The main task of any state , regardless of the device is to smooth regional disparities through a reallocation of financial resources. In this case, the stability of intergovernmental fiscal relations between the federal center and the subjects of the federation is largely determined by well-functioning system of fiscal federalism. Currently, the budget process is characterized by serious contradictions that arise during the development phase as well as on the stages of implementation of management decisions. Global experience demonstrates the lack of an optimal model of intergovernmental relations . Vertical alignment is the process of achieving a balance between the commitment of each level of government expenditure with the potential of its revenue sources . The tools include the vertical alignment of the fixing of taxes for a certain level , subventions and subsidies, regulating the distribution of income. The horizontal alignment is aimed at providing a unified standard level of consumption of public services to the residents of different regions of the country. With reference to the Russian economic space horizontal alignment problems are quite complex , since there are strong differences in socio-economic development of the regions due to climatic and historical factors .
