DEVELOPMENT OF AUTOMATIC CONTROL TEMPERATURE PRODUCT IN AIR-COOLING DEVICE
DescriptionIn the article, we developed two rational diagram of temperature change of the product in the air-cooling machine (no speed limit and the executive body of the actuator with speed limits of the Executive Body Elec-tric). We also developed two set points intensity, form-ing a rational chart changes in product temperature in the apparatus of air-cooling. The system of automatic temperature control product in the air-cooling appara-tus is synthesized

Description
In recent years, Russia has paid great attention to the theoretical and practical aspects of conservation. Since electric drives consume about 70% of electrici-ty generated, the most substantial savings achieved by using variable speed drives AC and DC. In this article, for the positional DC drive with speed-dependent resistance torque we have developed three energy-saving diagrams for large movements: with a speed limit of the drive; restricted maximum current anchor chain and speed electric motor; restricted maximum and minimum values of the current anchor chain of the motor and the speed of the drive. We have developed software to determine the parameters of energy saving diagrams for large movements of the executive body of the electric DC depending on the speed torque resistance. For the considered energy saving diagrams, which provide large movement of the executive body of the electric DC, depending on the speed of the moment of resistance, it is necessary to provide the following condition – the maximum speed of the executive body of the drive must be equal to the maximum allowable speed value. We have also defined analytical dependences, allowing calculating the consumption of the electric power drive by moving its executive body, in accordance with the proposed diagrams. Realization of the developed positional control DC motor with speed-dependent torque resistance will lead to energy savings

THE CALCULATION OF THE FOUNDATION SETTLEMENT OVER THE PLATE INVESTI-GATION DATA
DescriptionThe basis of foundation settlement modeling over the plate testing has been offered. The similarity criteria were formulated so as the formulas for settling incre-ments calculation versus to setting pressure increments on the base of foundation. New principle of admissible pressure on the base of foundation has been suggested

IMPLEMENTATION OF TRENDS OF MANAGEMENT ACCOUNTING IN SHORT TERM DECISIONS
DescriptionThe article, based on the concept of operating leverage, gives the examples of the use of quantitative measurements of the dependence costs, sales and profits, and formulated the direction of using the results in the adoption of short-term management decisions. We present recommended forms of management reporting, report on the cash flow, balance sheet management and management reports on the financial results, as well as giving some examples of division of fixed (semi-variable) costs of fixed and variable parts and bringing them into the form of a linear function. The article describes several methods for solving this problem: the method of the highest and lowest points, linear regression (least squares) and graphical method
