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...

Now in the global oil industry more than 50 million tons of raw materials are lost annually during the extraction, transportation and processing of petroleum products, which leads to widespread environmental pollution of the environment with oil waste. In view of the importance of the identified issues, various methods aimed at regular monitoring of fuel and energy complex facilities are of particular importance, with the aim of early warning and detection of oil product leaks, localization of their occurrence and...

Construction and further operation of buildings and engineering structures in karst-hazardous areas in most cases is connected with possible man-made increase of geodynamic manifestations of karst processes. As a result of this, in the soil foundations of engineering structures, the appearance of decompression zones with reduced load capacity is possible. In some cases, an active manifestation of karst-suffusion processes is possible. In this case, the probability of unacceptable deformations of the soil base with...
