Preface

This article explains the need for the research in the field of engineering terminology, the process of teaching it in foreign languages, the comparative application of engineering terms in different languages and studying the development trends. Objective of the article is to describe the methodology of teaching mechanical engineering terminology on the basis of study research in the field of mechanical engineering as a complex of heavy equipment in industry that produces household appliances, as well as consumer electronics and products of defense importance. Methods of the investigation that enabled to: study and analyze mechanical engineering terms; develop methodology of teaching mechanical engineering terms; analyze selection and assessment criteria of case studies; analyze selection and assessment criteria of project-based teaching; organize pedagogical experiments and analyze their results. It is an integral part to investigate the sphere of machine-building and metalworking industries, the production of metal products, metal structures and the repair of machinery and equipment. Furthermore, the issues of teaching engineering terminology in order to form professional foreign language competence in technical students by means of using new pedagogical technologies are of high significance. Such as, typology of terms in the field of mechanical engineering, teaching terminology whereby case studies and projects, examples of case studies and study projects are given. It is also important to pay attention to the etymology and the sources of the formation of terms, their peculiarities and definitions in special contexts as a complex human speech and language activity. Results and discussion. The article discloses the processes of activating terminology for obtaining information, through cognitive activity. Research works in the field of mechanical engineering, the practical basis of teaching terms and its effectiveness are also analyzed. The terms, vocabulary related to the field of mechanical engineering, case studies and analysis of independent work assignments are taken into account in the organization and conducting the trainings defined in the pedagogical experiment. As a result of experimental research, it was proved by mathematical statistical methods that the efficiency was achieved by 15% in case studies and 17% in educational projects. It was found that the mean value of the scores in the experimental group was 17% higher than in the control group. Hence, the research conducted has proven to be effective. Conclusions. The difficulties that arise in the process of comparing terminological activities show not only the specificity of individual languages, but also the specific role of terms in the national language system. Comparing the terminology of the English and Uzbek languages in the field of mechanical engineering not only allows to determine the general and specific features of the terms of mechanical engineering in the two languages, but also provides an in-depth study of both terminological systems.

It is very difficult to build a knowledge base in the mechanical engineering field. Because there is a great deal of complicated knowledge in mechanical engineering in comparison with other engineering fields. To build a large knowledge base, much research to connect Data Base System (DBS) and Knowledge Base System (KBS) systematically has been conducted. DBS is suitable for storing much knowledge but is not suitable for the representation of knowledge. Therefore, we believe it is possible in the mechanical engineering field to realize DBS characters in KBS by using an extended deamon function and extended system slot. If this system is realized, KBS will be suitable for managing and representing knowledge, and it will be easy to build a knowledge base in the mechanical engineering field. This paper describes the method of building a large knowledge base in mechanical engineering using an extended daemon function and an extended system slot, and "the realization of such a knowledge base."

Recently, the importance of system design in the field of mechanical engineering has been increasingly recognized. However suitable and useful methods for machine design are not yet established. An analytical method of the dynamic characteristics in the mechanical system, a method utilizing linear graph theory, is proposed. In this paper, for practical use of this analytical method, a program is developed which can analyze the dynamic characteristics automatically. As an example, in the mechanical vibration system, with the arrangement of the elements on the computer display, the system graph and the equations of motion are automatically produced by means of a cut-set matrix, and the dynamic characteristics of the system are derived by means of a computer algebraic method.

With the continuous progress of science and technology, the mechanical field is also constantly upgrading from traditional mechanical engineering to the mechatronics engineering and artificial intelligence (AI) is one of them. AI deals with a computer program that possesses own decision-making capability to solve a problem of interest with imitates the intelligent behavior of expertise which finally turns into higher productivity with better quality output.

Deployable lightweight structures are studied in the disciplines of architecture, civil engineering, aerospace engineering, mechanical engineering and other fields of their application. The research into these structures in individual fields resulted in a large amount of data sorted out by numerous classifications. The previously made classifications proposed by different authors are presented in this paper by the usage of reasonably unified tables that enabled a direct insight into the essential characteristics of these structures, their analysis and mutual comparison. One of the results of these analyses is the proposal for the unified classification given in a separate table in this paper. The results of interdisciplinary studies have been collected into a unified classification which could be applied for the research in different scientific fields, presenting the basic types of these structures, including individual elements and details with their characteristic features. The proposal of the unified classification of deployable structures is made according to the application of the basic elements used for structure forming. The suggested classification, with the review of the results of the present research, is a significant starting point for the scientists in different disciplines and it provides a detailed insight into the studied characteristics of these structures.

The University of Sunderland offers a range of degrees including Electrical and Mechanical Engineering, Media Systems, Automotive Engineering and Digital Systems. The School of Computing, Engineering and Technology has engaged in a major review of its undergraduate provision in these areas. The review encompassed the range and scope of the mathematical underpinning to be offered to students registered on the programmes offered in these areas of study in the short to medium term future. The history of the development of engineering mathematics teaching at Sunderland is considered and the author shows that the sensible use of modern tools such as computer algebra packages can offer distinct advantages to the students. Experience over several years has been gained in using such tools in the engineering mathematics situation and the author contends that the approaches and student experiences implied by the use of computer-based tools should become part of the mathematical experience of all undergraduate engineers. The paper illustrates some of the pedagogical advantages which may accrue to students by the intelligent sensible use of modern computer packages and focuses on an instance when it is definitely not an advantage to turn to the computer and a related instance when it most definitely is. Using these illustrations, the author builds a case which supports the fundamental contention of the paper that engineering mathematics is an essential and exciting field for student exploration provided that modern tools are used in an appropriate, logical and thoughtful fashion.

Bubble collapse dynamics near the composite walls: Progress and challenges.

Aim. To identify key features and trends in the process of trade in engineering products between Russia and Central and Eastern European (CEE) countries in 2020-2022.Tasks. To analyze the dynamics of Russia’s trade relations with CEE countries in the field of mechanical engineering (including electronics and electrical engineering) under sanctions; identify the main commodity groups in the structure of the mechanical engineering sector in trade between Russia and CEE countries; identify the impact of Western sanctions on trade in mechanical engineering products between Russia and CEE countries.Methods. The authors used such research methods as statistical analysis, observation, generalization, description and graphic modeling.Results. The results obtained in the analysis indicate that the export of machine-building products of CEE states prevails over the corresponding Russian exports to this region. The sanctions conditions have determined an unfavorable long-term trend in the trade of engineering products between Russia and CEE countries.Conclusions. The trade and economic indicators analyzed in this article have demonstrated a decline in the volume of trade interaction between Russia and the CEE countries in the machine-building sphere, especially the sharp decline in exports of the states of the region to Russia. Under the conditions of sanctions, both sides incur economic losses, which are higher for the CEE states. By freezing trade relations with Russia, the CEE countries are deprived of existing benefits and an occupied niche in the Russian market. Moreover, it will be difficult for the states of this region to find new markets for engineering products and to compensate for the losses due to the refusal of exports to Russia.
