During the process of drilling wells, it is necessary to have information about the composition of the soil layers through which the drill passes. This will optimize the parameters of rotation of the drill, the load on the drill, as a result of which equipment wear will be reduced. It will also make it possible to lay optimal trajectories during well drilling and track the penetration of the drill into the target layer. This issue is especially relevant for the oil industry, where production is carried out at grea...

The high performance characteristics of Peltier thermoelectric modules (TEM) in comparison with compressor cooling systems are determined by the convenience of their use for both cooling and heating, technological advantages due to the absence of moving parts, etc. To effectively regulate the temperature conditions of TEM, it is necessary to develop automatic control systems with specified characteristics. Modeling and design of such systems is complicated by the essentially nonlinear properties of the constituent...
