Abstract. This article highlights the fact that the development of unmanned aerial vehicles (UAVs) is a dynamically developing direction, which has recently been of particular interest to UAVs, as well as a number of their features and application areas. The main direction in the development of UAVs is to increase the autonomy of flights, which in turn increases the reliability of the device, provides ease of operation without requiring a high level of qualification of the operator, as well as reduces the overall cost of completing the task. We show the control system of an unmanned aerial vehicle, the impact of obstacles in the flight of an unmanned aerial vehicle and the presence of difficulties arising in the landing conditions.

Abstract. The advantages of the MRP system create favorable conditions for its (MRP) application in logistics markets to be profitable and effective. Thus, the mode of operation of these centers depends on the time of year, the political and economic situation in the countries where they operate, the development of the region, etc. The fact that the factors directly depend on the above advantages of the MRP system clearly demonstrates how convenient and economically feasible the use of these technologies is. From the above, it can be concluded that the use of MRP in logistics centers creates the ground for the development of transportation in the region.

Abstract. Aviation security refers to the state of an aviation system or organization in which the risks associated with aviation activities or directly supporting the operation of an aircraft are reduced and are at a manageable level. The most important direction in ensuring aviation security is to increase its level through the introduction of new, innovative technologies and technical means, simplifying and accelerating the procedures for checking air passengers. This article discusses innovative technologies and their role in ensuring aviation security. The novelty of the work lies in the use of new high-quality technologies that reduce the work of servicing passengers and improve safety. The reliability of the results obtained, the validity of scientific rules, conclusions and practical recommendations are confirmed by experiments and studies, as well as publications.

Abstract. Multiple input multiple output (MIMO) transmission can be used to increase the capacity of visible light communication (VLC) systems. This approach is well compatible with the use of micro light emitting diode (µLED) arrays. In this paper, we demonstrate a VLC-MIMO imaging system using a 2D array of individually addressable microLEDs and an integrated CMOS-based receiver. The total data transfer rate of ~920 Mbps is realized using four parallel channels at a distance of 1 m. Further increase in data transfer rate is possible by optimizing the system components and operating conditions.
Keywords: visible light communication, multiple input and multiple outputs, optical wireless communication.
Abstract. his article discusses the importance of the state language in the civil aviation industry. The degree of use of the state language in the aviation industry is analyzed. The degree of use of the state language in the aviation sector is analyzed. Using examples, it was analyzed to what extent aviation industry specialists speak the state language in the airport transport service, at the check-in counter and in the aircraft cabin. Issues in the field of civil aviation of the Republic of Kazakhstan are analyzed, allowing further expansion of the scope of the use of the state language in public and professional relations, including in the aviation transport system. The article says that knowledge of the state language is a civic duty.

Abstract. A new method to achieve high speed visible light communication (VLC) using white light generated by a blue GaN µLED and a yellow fluorescent copolymer is presented. We generated white light suitable for indoor lighting by optimizing the ratio between the blue EL of a µLED and the yellow photoluminescence of a copolymer color converter. Taking advantage of the high bandwidth of the components, we achieved 1.68Gbps at 3cm (at 240 lux). To the best of our knowledge, these are the fastest white light VLC results using a single blue LED and color converter combination.

Annotation. This article presents an approach to optical communication using visible light using a focusable LED flashlight as a transmitter and a digital camera as a receiver. One of the innovations of the approach is that the design can integrate standard light source and camera components and is designed to work indoors under typical lighting conditions, i.e. overhead lighting and ambient daylight. The communication signal is transmitted as a sequence of values (1,0) that turn the light source on/off. The camera receives the signal by observing the presence/absence of a projected light spot on the intermediate surface and converting it back to a binary signal (1,0). The approach applies image processing techniques to calculate the received signal from the recorded image from the camera.

Abstract. This paper shows for the first time that the problem of continuous downhole monitoring in the oil and gas industry is effectively solved through the use of visible light communication (VLC). As a reliable, flexible and low-cost method, VLC can meet the critical need of operators to maintain production efficiency and optimize gas well performance. The proposed VLC system uses a Light Emitting Diode (LED) transmitter and a highly sensitive single photon detection receiver called a Single Photon Avalanche Diode (SPAD). The latter plays an important role in enabling communication over long distances, and the fact that there is no ambient light in the gas pipe is exploited.In particular, the absence of ambient light provides a high signal to noise ratio (SNR) in a receiver that operates in photon counting mode. In this study, the bit error rate (BER) performance of the system is simulated for a 4 km long metal pipe. The proposed system is shown to be more energy efficient than traditional methods, which is important because the transmitter is assumed to be battery powered. In addition, the theoretical BER performance is calculated and compared with simulation results.

Abstract. The purpose of considering the application of case-study methods in the form of watching a video in professional English lessons is to develop interpersonal communication for all participants in the educational process. Indeed, in conditions of situational learning, it is very important to maintain the interest of students through the mutual exchange of information in a professional environment.The peculiarity of learning on the example of a video excerpt is that it contributes to the involvement of students in an active role-playing situation on a given topic, and the teacher directs their activities to achieve the goals of the lesson.
Keywords: educational process, case study, professional communication, group work, role-playing situation.
Abstract. The academic performance of the study group is tracked at each stage of the monitoring of the educational process in the university. Changes in the learning process related to academic performance require constant monitoring, adjustment, and management. In every situation or human life, for example, if we talk about health, it is better to do preventive action than to treat the consequence of disease. In the learning process, by analogy, it is easier to prevent the worsening performance of a study group than it is to look for the fault after a failure. To achieve this, it is necessary to forecast academic performance in advance, to carry out preventive work in study groups. The aim of the article is to find ways to predict the performance of the study group, knowing the result of the previous exam or the control of the study group. In the course of preparing the article, along with general methods of analysis and synthesis, comparison and generalization of mathematics, basic concepts of probability theory, applications of the derivative, and methods of solving the differential equation were used. As a result of the study, a time-dependent function of academic achievement is constructed. This function has been analyzed with respect to the parameters. The behavior of this function when each parameter included in this function is modified individually has been established. The use of the learning achievement function is demonstrated, and ways of using it to predict the result of the next exam are shown. Using this model, you can evaluate the preparation of the study group, their organization, the work of the teacher in the subject and the curator of the group.
