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...

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...

On a global scale, every year the environmental problems that arise when using traditional methods of obtaining heat and cold are becoming more and more relevant. In this regard, and also in view of a number of successes in the field of materials science, in recent years, the thermoelectric Peltier effect has been of increasing practical interest to researchers. So for several years, the average increase in the global production of thermoelectric modules and thermoelectric devices for various purposes was about 15...

The article considers the problem of predictive estimation of deformation processes of geotechnical control objects. It is noted that the main task of geotechnical monitoring is the rapid identification and geodynamic forecasting of geological processes that may affect the safe state of life-supporting and man-made objects, in order to timely develop and take measures to prevent and eliminate emergency situations. One of the most effective ways to timely predict the beginning and activation of deformation processe...

Modern space complexes are designed to solve a wide range of tasks, including remote sensing of the Earth in order to assess the geoecological state of territories. The transmission of super-resolution images obtained as a result of sensing to ground-based control systems is traditionally carried out by space telecommunications systems, the requirements for technical characteristics and parameters of which in terms of the speed of information exchange and the reliability of communication are constantly being tight...

The article deals with the problems of designing multi-channel high-frequency signal generators for the transceivers of unmanned aerial vehicles (UAVs). It is proposed to use high-speed digital-to-analog converters to increase the output frequency and improve the noise characteristics of UAV transceivers. The possibility of using special operating modes used in modern high-speed direct-to-analog converters (DACs) for digital generation of broadband signals is shown. 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. The purpose of the control is to assess the current state of the object based on the measured geotechnical data and to forecast the development of possible destructi...

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. To quickly eliminate possible contamination, it is necessary to solve the problems of their early detection, localization and forecasting with the help of special technical means. In this aspect, it is promising to use groups of geoelectric control methods that allow to effectively regi...

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...

During the process of drilling wells with a complex spatial profile, it is necessary to obtain timely information about technological processes in order to control them. This issue is relevant for the oil and gas industry, since the number of works of increased complexity is constantly growing. This article discusses the technique of vertical tomography in control problems during directional well drilling. The object of control in this case is the technological equipment, the well and the surrounding soil. The art...
