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...

Flying ad-hoc networks (FANET) based on unmanned aerial vehicles (UAVs) are characterized by frequent changes in the network topology, which is caused by switching nodes on and off, as well as their movements in space. These aspects of the FANET operation determine the relevance of the development of new routing protocols, which differ significantly from the protocols of hierarchical networks with a constant topology. One of the key problems of FANET is the high overhead costs for transmitting service messages abo...

Mathematical models of noise characteristics at ...

The paper considers the methodology and algorithms for integrating geotechnical control methods in assessing the stability of natural and technical objects. In the process of creating data processing algorithms for control systems of natural and technical objects, it is necessary to be based on the purpose and system methodology of the control itself.

An important practical task in the study of any measuring devices and systems is to assess their sensitivity. Such systems include, in particular, hardware and software systems for geodynamic monitoring of geological environments for leaks of petroleum products (from areal storage and processing facilities), implemented on the basis of the phase-based method of geoelectric control. The idea of this method is based on the fact that various petroleum products have their own unique electrical characteristics, contras...

The quality of agricultural products grown and collected at the facilities of the agro-industrial complex and the raw materials obtained for various industries largely depends on the ecological state of the geological environments.

Peltier thermoelectric modules (TEM) have a number of key advantages over compressor cooling systems (ease of use for both cooling and heating, high operational characteristics due to the absence of moving parts, etc.). Ensuring smooth and accurate regulation of the TEM temperature regime requires the development and application of effective automatic control systems. To create complex temperature change profiles, it is necessary to increase the order of the control system, which causes a stability problem. To ana...

Currently, the growth of agricultural production in Russia is closely related to the pace of scientific and technological progress in the agro-industrial complex, which is largely determined by its level of energy supply. The most significant consumers of energy in the agro-industrial complex are livestock, poultry complexes and enterprises associated with food storage. In animal husbandry, energy costs are the second largest after feed, with more than 30% of the energy consumed in creating a production microclima...
