Abstract. The article considers the method of synthesis of an optimal UAV flight path and an algorithm of the flight control system. The system and algorithm are designed for four-dimensional (4D) trajectory-based operations (TBO) in the context of the CNS/ATM and PBN concepts, which will increase the operational efficiency of the UAV navigation and piloting processes. The paper presents a mathematical model of the control object and algorithms for forming a time-optimal flight path. An assessment of the proposed methodology is also presented by verifying and validating the system software using simulation modeling. The results obtained demonstrate the functional capabilities of the control system to create time-optimal profiles of trajectories that meet operational requirements.

Keywords: unmanned aerial vehicle (UAV), control system, optimal flight path.

Abstract. The main idea of the article is devoted to the problem of reflecting in language the processes associated with changing human attitudes towards animals in modern society. The focus of the research is on the zoomorphic lexical unit “tierfrei”. The research was based on 130 examples of the use of the “tierfrei” token in the DWDS corpus. On the basis of several discourses, 4 main meanings of the declared lexeme were identified and systematized in terms of its pragmatic function. Based on the linguistic material obtained, the authors can draw the following conclusions that take place in modern German society and influence the formation of the German national picture of the world: 1) the “tierfrei” lexeme is a neologism and has been actively used by native German speakers only since 2007; 2) the “tierfrei” lexeme can have four main meanings: “without the presence of animals”; “without the content of animal products”; “without elements of animal origin”; “without experiments on animals”; 3) the “tierfrei” lexeme can be found in such discourses as culinary, medical, advertising, in each of which it performs its pragmatic function; 4) the appearance and active use of the word “tierfrei” in the texts of the German-speaking space indicates that changes are taking place in modern German-speaking society associated with a rethinking of the role of animals in a person’s life.

Key words: zoomorphic lexical unit, German language picture of the world, corpus, meaning, pragmatic function, culinary discourse, advertising discourse, human attitude to animals.

Abstract. Assessing the technical condition of glazing elements in the cockpits of operational-tactical aircraft still remains the most important task in ensuring flight safety. To increase the efficiency of operations for non-destructive testing of glazing elements using the speckle structure method of optical radiation, the authors propose to use neural network technologies to automatically identify controlled areas in the cockpit. Artificial intelligence technologies have been used to realise this task. They are based on algorithms of semantic segmentation, classification and detection of monitored areas according to the established markers on the cabin due to the application of convolutional neural network on YOLOv8. The application of machine vision technology have made it possible real-time measurement of the glazing exit from the termination when overpressure has been created inside the cabin. This reduces the time for technical condition assessment by at least 10 times. The use of machine vision technologies have made it possible to measure the value of the glazing outlet from the sealing in real time when creating excessive pressure inside the cabin and thereby reduce the time to assess the technical condition by at least 10 times. The authors have established the reason for the discrepancy between the results of using the speckle-structure method of optical radiation in determining the value of glazing yield from the termination and the “tape” method and developed recommendations to reduce measurement errors.

Keywords: non-destructive testing, optical-electronic systems, speckle, semantic segmentation, convolutional neural network, YOLO, glazing.

Abstract. The article discusses linguistic representation of human knowledge about future events, processes, situations. The study focuses on prospective categorization of the reality. More specifically the paper considers linguistic conceptualization and categorization of forecasting as a cognitive activity. The author states that modus category of PREDICTION involves cognitive operations of interpretation, modalization, and evaluation of the conceptual content. The paper discusses discursive construal of future climate changes in English media. The findings obtained may be helpful for further study of the modal categorization as one of the forms of knowledge representation in language and its interpretative potential.

Key words: probabilistic knowledge, prediction, modus, modus verb, modus category, interpretation.

Abstract. The article contains a plot analysis of the film image of the family and family education in Russian feature films (1920-2020). The thematic variety of plots is associated with the representation of family and family education. It includes such traditional topics as intergenerational conflict (the problem of “fathers and sons”), the preservation of family values in the light of their historical transformation in the lives of several family generations, challenges of young families and their relationships with representatives of the older generation, the film image of adoptive parents and the problems of adopted children, social orphanhood and homelessness, hardships of large families, loss of family members, family reunions, the film image of a happy family. Further analysis of the transformation of the theme of family and family education in Russian audiovisual texts remains relevant both in cultural and media education aspects.

Keywords: family, family education, cinema, film adaptation, media education, film education, film, critical thinking.
