Annotation: The issues of the effectiveness of foreign language teaching to non-linguistic students do not lose their relevance in modern society since confidence in a foreign language significantly increases the competitiveness of any specialist. Special attention is paid to the choice of pedagogical technologies that will contribute to a more effective mastering of a foreign language by students. This paper discusses the features and possibilities of using CLIL technology which allows organizing the process of foreign language teaching to non-linguistic students through the integration of a foreign language with specialized subjects. The paper reveals the essence and the main characteristics of CLIL technology and describes the experience of practical application CLIL technology in foreign language teaching to undergraduate economics students in Kozma Minin Nizhny Novgorod State Pedagogical University. In conclusion, the advantages of CLIL technology in foreign language teaching to non-linguistic students are listed, as well as the possible difficulties that a teacher may face in practice.

Annotation: Modern technical systems are complex dynamic objects with automated or automatic control. Advanced in this direction are objects of aviation, space and rocket technology. However, the increase in the number of functions performed by them, the complication of work algorithms, and the transition, as a whole, to intellectualization highlight the problem of their maintenance, i.e. assessment of the state for a given control. In practice, the study of the properties of dynamic objects, for example, space technology, is carried out by mathematical modeling of the behavior of an object in conditions close to real ones. Moreover, the quality of the assessment of the state parameters of the object determines the adequacy of the mathematical model to the real object. In this case, the main attention is paid to improving accuracy, reducing computational costs and stability of algorithms for assessing the state of a remote controlled object (spacecraft). The article considers a new state estimation algorithm based on synthesis combined with physical principles that satisfies the indicated conditions.

Annotation: The article deals with the scientific problem of modeling the processes of complex organizational and technical systems that are not described by simple mathematical models. The application of model organisms used for studying the properties and phenomena of living nature, their transformation into the field of modeling the processes of complex organizational and technical systems is studied. The properties of complex organizational and technical systems that represent a hierarchical structure of different topologies are considered. Hierarchical systems are widely used in information management and processing. The main concept of the article is that it is recommended to model complex organizational and technical systems using analogs from the field of living systems. The equivalence and similarity of living and technical systems is determined. The directions of research in the field of evolution of organizational and technical systems are determined. The article considers the theory of development of complex systems based on the Luman theory. His concept of autopoiesis is analyzed. It is shown that with increasing external and internal complexity, hierarchical systems evolve into subsidiary systems that contain an element of self-development.

Annotation: The presented research is devoted to computer modeling of interaction between shock waves (SW) and streamers of the high-frequency discharge in connection with the problem of sonic boom. Currently, there are a number of works relating to the use of plasma to attenuate the sonic boom. The authors of the article consider the creation of hot filaments (filaments) by different plasma sources. In the approaches associated with the use of microwave discharge, the propagation of SW through hot filaments is assumed, causing their explosion and affecting the SW itself. This work is devoted to the study of the propagation of SW through the microwave discharge strands in order to determine the parameters of filaments, at which the influence of microwave discharges on SW can be exerted. Lengths and temperatures of microwave streamers were obtained at which the interaction of microwave filaments with SW occurs: they usually corresponded to filaments with a width of 0.1-0.5 mm, a length of more than 0.5-1 cm, with an internal gas temperature of more than 2500 K. The filaments should be directed at some angle to the SW. In the course of the study, no significant effect was obtained when the cross-section of the filament is perpendicular to the direction of motion of the SW. According to experimental data, electric fields in streamers (our hot filaments) can be in the range of 25-75 kV / cm at atmospheric pressure, the authors made calculations at 25 and 40 kV / cm. The plasma created in filaments by electric discharges with an electric field value equal to the critical breakdown field of 25 kV/cm and the supercritical electric field of 40 kV/cm was considered. Electrons are initiated by a background atmospheric source of electrons 4 and 10 (cm3*s)-1 corresponding to atmospheric conditions.

Annotation: The paper describes a specialization of a model-driven development approach for transformation of subject domain conceptual models to the structures of a case base, their subsequent refinement and execution. The basic principles of the model-driven development approach are highlighted, the implementation of model transformations in the process of creating intelligent systems and knowledge base is stated. The formalized statement of the problem of prototyping of case bases is presented. The architecture of the author’s software that implements the methodology of the model-driven approach, taking into account the specifics of the case bases of the subject domain is considered. The technology for knowledge bases engineering on the basis of consecutive transformations of models with various degree of abstraction is presented. Experience of development of case-based expert systems and case bases with application of model-driven approach and developments in the field of model transformations is stated.
