Abstract. The article analyses the modifications of the concept «limita» in the context of song discourse. To solve this problem, the method of analysis of dictionary definitions and inductive frame allocation, discursive and stylistic analysis, conceptual analysis, description of cognitive metaphor, and contextual interpretation were used. The study reveals the expansion of the concept through several key frames, including social, economic, emotional, historical and «migration» ones. Considering the given concept from different points of view, the frame analysis reveals its social, economic, emotional, historical and migration aspects. The analysis of the concept «limita» serves as an example of how song discourse can reflect and shape social stereotypes. The study shows that song discourse not only entertains, but also performs an important social function, contributing to the formation of public opinion and identity.

Keywords: concept, anti-concept, frame, song discourse, linguoculturology, cognitive linguistics, functions of discourse.

Transistor switches driving in ADS-B / mode 4 amplifiers

Abstract. Design process of highly efficient means of communication, surveillance and navigation using switch-mode amplifiers requires a revision of traditional approaches to the circuitry of radio transmitting devices. The parameters of the physical layer of ADS-B systems using VHF datalink mode 4 (VDL-4) theoretically allow the use of switch-mode amplifiers as part of their transmitters. Such an improvement plays a particularly important role in the context of integrating unmanned aerial vehicles (UAV) with limited energy reserves on board into the general airspace.

One of the important tasks in the design of such radio technical support for flights operating in the VHF range (primarily onboard, but also ground-based) is to determine approaches to control transistor switches of a power amplifier based on the criteria of efficiency, stability and the ability to provide different operation modes of the switch-mode amplifier. Requirements for the control device have been developed taking into account the standard for the physical layer of VHF datalink mode 4. A conclusion is given on the optimal solutions suitable for building a VDL-4 transmitter with a switch-mode power amplifier, opening up prospects for increasing the efficiency of more than 90%, compared to today’s not exceeding 46%.

Keywords: VDL-4, VHF mode 4, radio transmitter, switch-mode power amplifier, modes (D, DE, E), integrated circuit.

Abstract. The article provides an overview of the applicability of statistical methods for assessing the results of production processes in various industries. The authors emphasize the effectiveness of the system approach implemented in the methods of analysis of variance, which contributes to technology improvement and allows the influence of each factor and their interaction to be studied in detail. In addition, the results of the analysis of variance can be integrated into the quality management system, which makes it possible to continuously monitor and adjust production processes, and prevent deviations in the output parameters of various parts. The paper provides an example of applying the analysis of variance in the study of technological processes of pressing the components from various materials in designing, manufacturing and controlling the quality of defense and industrial products.

Keywords: analysis of variance, statistical methods, experiment, technological process.

Abstract. The article proposes a mathematical model for validation of messages of automatic dependent surveillance of broadcasting type (ADS-B). The relevance of the study is due to the growing requirements for the security and reliability of information systems, as well as the need to ensure the integrity and reliability of transmitted information in the context of modern threats. The paper presents the main components of the model, including information sources, data transmission channels and error detection mechanisms. The proposed model describes the processes occurring in the ADS-B systems, taking into account artificial and natural interference that affects the reliability of surveillance information, allows you to predict the actions of intruders trying to violate the integrity of the ADS-B systems, and to predict the operation of the ADS-B system under interference, provides the possibility of developing effective methods to validate ADS-B messages in the terminal area. Thus, the presented mathematical model for validating ADS-B messages serves as an important step towards improving the reliability of information systems and protecting critical information from unauthorized access and distortion.

Keywords: ADS-B, time difference, model, validation.

Abstract. The article proposes a method for automated high-precision assessment of the danger of approaching aircraft in case of violation of established separation standards on a continuous 100-point scale. The technique is a step-by-step search for the maximum hazard of approaching aircraft from the moment of the beginning of the violation of separation intervals to the end of the conflict situation. The main criterion for assessment is the linear functional dependence of the values of the minimum distances between aircraft, weighted in the established separation standards. A 100-point assessment will allow for the comparison and comparison of potential hazard between different facts of violations of separation standards, the severity of the threats and risks to flight safety contained therein.

Using “perceived hazard” as a reference points allows assessing the level of flight safety even in the absence of violations of separation intervals for the selected reporting period. The analysis of the estimates obtained using the methodology will help to take timely preventive measures to eliminate potential threats even before the occurrence of real aviation events.

It is advisable to use this methodology in solving the tasks of automating the assessment of practical skills of air traffic control personnel and creating an automatic flight safety management system.

Keywords: normalized coordinate system, normalized distance, violation of separation intervals, hazard of convergence, methodology for assessing the hazard of convergence.
