In the context of the autonomous functioning of special equipment in the Far North and the Arctic is necessary to use its internal resources to maintain optimal thermal state units and units. This can be accomplished using a heat recovery system of the internal combustion engine. For this purpose the heat accumulator. The mathematical modeling of the thermal state of the heat accumulator in the cooling stage. The main factors affecting the cooling time of the thermal battery: TA insulation thickness, weight coolant, coolant temperature, air temperature, wind speed. Also developed a mathematical model of the process of cooling the heat accumulator in general terms. It is presented in graphical form, which simplifies the determination of the time of cooling the heat accumulator in its design. For the definition of Q and Bi developed a program «Time».

in modern conditions become widespread trenchless methods for the construction of pipelines. The positive features of their use include increased speed pipeline installation, reducing the volume of excavation, etc. Existing regulatory documents limit the bending of the pipe at low temperatures need to be tested in terms of their applicability to new grades of polyethylene. The aim of this study was to determine the minimum permissible bending radius of the track, the passage of which in the conditions of negative temperatures polyethylene pipes PE80 would maintain its strength characteristics. By using a mathematical model dependency of the elastic modulus and yield point are calculated from the temperature stresses in the walls of pipes of different diameters in bending under different temperatures. In order to establish empirical relationships voltage on the pipe diameter and the radius of its bend procedure is carried out function approximation method of least squares. Presented obtained graphic dependences. Using the values ​​of the yield strength of the material at different temperatures were calculated bending radius of all dimensions. If the production of the track plow trenchless pipe-layer will be considered given the conditions, you will be provided with the necessary conditions for installation.

The quasi direct currents, which flows through the winding of power transformer, could cause the migration of working point from the knee of the magnetizing curve to the zone of saturation. In that way, the operational mode of power transformer changes. To account the effect of quasi direct current on the operational mode of power transformer was described the model of winding of power transformer with endless magnetic core and cylindrical magnetic cover. Compare the results of accounting model with the model of winding without effect of cylindrical magnetic cover the 20% difference in the characteristics of inductance from magnetizing current in the area of magnetizing currents under 100A was achieved.

Hemodialysis is a complex process requiring the increased control of some parameters, such as dialysis dose, blood perfusion rate, ultrafiltration, blood volume, its composition and etc. To solve the problem of control the blood during dialysis was designed the monitoring system of air inclusions - air bubbles. A very important part of this system is the ultrasonic air detector. It is set to venous blood highway - at the exit of blood from the dialyzer, and determines the presence in the cleaned blood any air inclusions by measuring the velocity of ultrasound in the analyzed multiphase medium - the blood, thus informing the doctor about the quality and security of hemodialysis procedure.
