Non-linear elements are widely used in various automation devices, converting and measuring equipment. They are often presented in the form of diode-resistive circuits. In single-circuit electrical circuits, their calculation by a numerical method reduces to compiling nonlinear equations and solving it using the Newton-Raphson method with specifying reasonable initial conditions for the calculation. The article is aimed at determining the dimensions of the Jacobi matrix in numerical calculations of nonlinear chains. Using the example of numerical calculation of two simplest schemes with nonlinear elements, it is shown that by eliminating the coordinate chain (system equations) from the system of equations that do not contain nonlinear elements, the Jacobi matrix is reduced in size

Analysis of geological prospecting, geological surveying, geochemical and other materials of the territory of the Malguzar Mountains allows us to note that here the ore-bearing formations are Silurian formations (sandstones, gravelstones, shales), crumpled into folds, which are complicated by a series of faults of north-west strike, zones of splitting and etc. These structures are rectilinear, their zone is characterized by the presence of small fracture structures, areas of swellings (Liyagun mineralized zone) and splits (Ardakshan area). The reason for these swelling and splitting, where gold mineralization is noted, remains not fully studied. The importance of studying these features of ore-controlling faults is determined by the confinement to their zones of gold mineralization and geochemical halos of the main 5 ore chemical components. Consequently, the identified ring structures of the Malguzar Mountains are signs of deep granitoid magmatism, with which gold ore mineralization is genetically related. In the course of the study, linear structures of northeastern striking were established, which, together with northwestern and sublatitudinal faults, form the block structure of the study area

The pulse-frequency control systems are widely used in radar, space industry, for control of technological processes and robots and many other areas. Today, there are various approximate and accurate methods for the analysis and synthesis of pulse-frequency systems (PFS). However, the area of the practical application of the existed methods is mainly limited to single-variable systems. The classical methods provide the consideration of the initial structures of pulse-frequency systems as a whole. This article proposes the decomposition method for modeling and research pulse-frequency automatic control systems. The method is based on the mathematical apparatus of signal-flow graphs. We can use the method for analysis and synthesis of both single-variable and multivariable automatic control systems with pulse-frequency modulation

The non-contact measurement method development is caused by the need for precise measurement and elimination of an operator’s errors. The purpose of the atticle research is to develop a reliable small scale prototype model of non-contact point measuring system. The mathematical model of robotic articulated arm has been developed to analyze the forward kinematics. Then, the prototype model of a robotic arm and laser-sensor mounted technique have been developed to take the measurements. The idea was derived from the coordinate measuring machine working principle, that puts the tip or tool center point in the known position with necessary precision. Most of the production engineers rely on the measurement data obtained from the CMMs. Most of the CMMs used in Uzbekistan are mainly contact based CMMs that have a number of disadvantages, i.e. a liitle inspection time. Also, the ergonomics and redundancy of the CMMs body frame are not acceptable. The surfaces of a vehicle body frame are designed in the free forms to give better aerodynamics and smaller resistance coefficients that result in difficult shapes that is not possible to reach easily with the ordinary CMM. The scientifically-developed robotic arm based on the non-contact CMM helps to cope with this issues

The method of laser scanning, used in combination with the traditional mine surveying, is one of the most effective and safest ways to carry out mine surveying and instrumental observations on deforming areas of open mining objects. The article presents the results of ground-based laser scanning of the Kharanutsky coal pit and a comparative analysis to determine the deformations and displacements of the sides for different periods, which was performed in the RISCAN PRO environment. Digital elevation models (DEM) were built, distinguishing observation cycles by color. As a result of comparison, the places of manifestation of deformations and displacements were revealed. Based on the results of geomonitoring, it was concluded that critical displacements and deformations were not detected, despite the places where small rockslides were manifested, and further systematic observations were recommended. The results of laser scanning are confirmed by the data of satellite observations on the control points and the survey of the section sides

The article presents the issues of prevention and prevention of processes related to ensuring safe and comfortable working conditions in the development of coal deposits, namely the study of spontaneous combustion of coal Angren deposit. Chemical activity of coals at low temperatures contributing to spontaneous combustion is emphasized, as well as the influence of hot climate in the region on the increase in chemical activity of coals. In this connection, climatic conditions of the region have been studied, i.e., increased temperature (from +250 to +500C) gives a sharp increase in the chemical activity of Angren coal. The main parameter that characterizes reservoir properties and filtration coefficient, showing the ability of the reservoir to let fluid through under the influence of the applied pressure gradient, is determined. The causes of spontaneous combustion are studied, depending on the rate of oxygen sorption by coal, reducing its pre-injection of water into the coal bed before excavation, the method of calculation of determining the incubation period of spontaneous combustion of coal is given

The practice of drilling has proven that the use of compressed air as a cleaning agent provides a significant increase in ROP (mechanical drilling speed) and reduces the time spent on eliminating geological complications, which sharply increases the productivity and economy of drilling operations. However, air has a low heat capacity compared to liquid flushing solutions, this affects the operation of rock cutting tools through high contact temperatures with irreversible consequences such as deformation of matrices, destruction of diamonds, grinding, reduction of diamond hardness and tool burns. To prevent these problems, there is a need to develop technical means and technology to effectively ensure the temperature regime of the rock-cutting tool. In addition to normalizing the temperature regime of the rock-cutting tool, there is the problem of increased energy consumption of drilling due to the use of compressor units, the drive power of which is much higher than that of pumps used in similar conditions. This article discusses the possibility of normalizing and regulating the temperature regime of the rock-cutting tool due to forced cooling of the cleaning air at the bottom hole to negative temperatures. It also describes the possibility of increasing the efficiency of drilling wells with air blowing by using a heat recovery unit for compressor drive heat and excess air, and presents the results of experimental tests to determine the effect of the ejection of exhaust gases from an internal combustion engine on the efficiency of its operation
