Abstract. The work is devoted to the creation of universal software for the development of computer models of systems that allow studying the parameters and characteristics of the reliability of systems based on the structural scheme of reliability, and the methodological principles of using the proposed software in the analysis of the operational properties of systems in their design. The software is an application (Toolbox) of the Simulink dynamic modeling system. Algorithms and programs are unified, grouped by purpose, designed to form mathematical and computer models of complex structural reliability systems. The proposed software allows performing a computational experiment to analyze reliability characteristics and to evaluate the effectiveness of measures to improve the reliability of technical and technological systems; it is enough to simply modify mathematical models; organize a software interface; process simulation results. The features of the software make it possible to effectively change both the characteristics and reliability parameters of the system elements and the structure of the interrelationships of the system elements from the point of view of the reliability of the entire system as a whole. The paper provides an example of using the software.

Keywords: SIMULINK, MATLAB, reliability, methods for calculating reliability parameters, reliability block diagrams, reliability of technical systems, reliability of technological systems, reliability of machines.

Abstract. The article analyzes the results of two independent sociological surveys of students of Volgograd State Technical University and other major state universities of the city. The purpose of the research is to identify the problems of urban public transport and study students’ requests for this urban life sphere. This problem affects not only the current students’ interests, but also applicants just making their professional path choice. And quite often this choice is predetermined by transport availability of higher education institution. Today, Volgograd students make up almost a quarter of the active working-age population, so their requests for transport services are quite logical and legitimate. Such research has not been conducted in Volgograd before. According to the results of the study it was determined that most of the students have to get to the university with transfers, and the updated today transport scheme of the city creates even more difficulties in movement due to increasing time and financial costs.

Keywords: urban public transportation, students’ opinions on transportation, unmanned city bus.

Abstract. In civil aviation, an urgent and important task is to provide air traffic participants with uninterrupted radio communication. Satellite communication is a global mobile network covering the entire surface of the Earth, including polar regions, which provides a two-way data and voice communication exchange. An analysis of the principles of functioning of satellite communication systems (SCS) showed that the determination of energy characteristics is of great importance. Energy characteristics in satellite communication channels and the level of interference determine SCS operational capabilities and quality indicators. One of the critical factors that determine the effectiveness of the SCS functioning is the conditions for the propagation and absorption of radio waves, including ionospheric phenomena, which are not yet fully understood, and this determines the research relevance.

This article is devoted to theoretical studies of the ionospheric plasma by the methods of physical kinetics to increase the energy potential of the radio links of a satellite communication system.

Keywords: physical plasma kinetics, energy relations, satellite communication systems, Maxwell distribution function, ionospheric phenomena.

Metadiscourse analysis of new year’s addresses of the Russian President

Abstract. Political discourse is not only an information environment, but also an interactive space which necessitates the study of metadiscourse as an effective rhetorical strategy. The purpose is to study metadiscourse categories in the genre of the President’s New Year’s address as one of the genres of political discourse. To achieve this goal, the metadiscourse categories used by the Russian president are identified and their communicative functions are determined; the frequency of markers within the metadiscourse categories is determined. New Year’s addresses posted on the official website of the President of Russia were used as research materials. The taxonomy of metadiscourse markers proposed by K. Hyland was adopted as the methodological basis. The study identified five types of metadiscourse markers (boosters, hedges, attitude markers, self-mentions and engagement markers) used by the President in order to construct an effective dialogue with an audience. In the discursive space of the New Year’s address, these metadiscourse markers serve the following communicative functions: showing confidence in the truth of a proposition, manifesting solidarity with an audience, mitigating categoricalness, showing emotions, engaging the addressee in a dialogue, accepting personal responsibility for the utterances produced. The predominance of boosters and attitude markers that increase the illocutionary force, demonstrating the addresser’s confidence in the truth of the propositions, and explicating the speaker’s affective stance, indicate Putin’s desire to construct an image of a self-confident leader and establish an emotional connection with the audience. The results obtained indicate the need to study metadiscourse categories as crucial elements of political communication. Intercultural, intracultural or diachronic studies of metadiscourse in the New Year’s addresses of the presidents seem promising.

Key words: President’s New Year’s address, political discourse, metadiscourse, hedging, boosting, self-reference, attitude marker.
