Description
This article has examined the signs by which you can group all the technical means to collect information about the interaction of termobarometrical underground oil and gas facilities with the environment. The analysis showed, that despite the long history and variety of instruments for measuring pressure and temperature, there is a small set of tools for measuring deep inside the well bore, we know only a few works on the casing tube inserted into special tubes with tensometers placed on them to measure the mechanical deformations, axial forces and temperature, and only a few details about the individual experimental studies of total pressure at the borehole wall and the temperature. Unknown devices to measure except in the casing annulus pressure of the total pressure generated by a separate solid and liquid (gas) phases of the environment

OPTIMUM SPEED OF DIAGRAMS FOR CHANGES OF TEMPERATURE OF A PRODUCT IN THE DEVICE OF AIR COOLING
DescriptionThree diagrams are developed for the changes of temperature of a product in air cooling devices with restrictions of speed of the systems’ performing parts of electric drive and it’s various derivatives at dispersal and braking. Parameters of optimum diagrams of speed for the big changes of temperature of a product in devices of air cooling are defined

Description
In the article, we considered one of the approaches of the dataware of the syntheses to virtual reality in con-dition of the ill-defined presentation controlled pa-rameters. Particularity of the approach is a possibility of processing of object of virtual reality on the base of the rules of the inference with use of the algorithm of Mamdani
