Ontology-Based Modelling of State Machines for Production Robots in Smart Manufacturing Systems

The integration of modern IT technologies in production equipment does not only enable them to acquire information from different sources and provide it to others but also to make decisions depending on the situation. Due to the limited processing power of such equipment, usage of state machine to describe and program it is considered a promising direction. However, the necessity of intensive interaction of the equipment units causes problems related to interoperability, which are usually solved with the usage of ontologies. The objective of the presented research is to model state machines of production robots via ontologies. The results are demonstrated on the example of a fragment of an automated production line.

Belief revision as a problem of scientific epistemology

The fundamental question that must be answered by any theory of knowledge that claims to be adequate is the question of how it is possible to change our knowledge. The very fact of change undoubtedly takes place, and the problem is to theoretically explicate this fact. The methodological significance of this issue is due to the fact that changing knowledge means nothing more than its development, namely, the question of the ways and means of developing our knowledge is of central importance both for the logic and methodology of science, and for general epistemology. This work is of a review character, and aims to draw the reader’s attention to a new promising direction in the modern theory of knowledge called “belief revision”.

To the Problem of Protection of Medium Voltage Instrument Transformers with Fuses: Analytical Research

Introduction. In the medium voltage power grid of 6–35 kV, there is a problem of protecting voltage instrument transformers. This is due to the insufficiently effective level of their protection with fuses. Recently, there have been more and more reports of accidents associated with the failure of voltage instrument transformers not only in Ukraine, but also abroad. The issue of conducting an analytical study of the problem of protection of medium voltage instrument transformers by fuses is relevant. Goal. Investigation of designs and characteristics of fuses for medium voltage instrument transformers to improve the efficiency of their protection. Results. The article shows that protection of medium voltage instrument transformers with epoxy insulation is often provided by fuses, in which the nominal current of the fuse-link is significantly higher than the maximum permissible long-term current of the primary winding of the instrument transformer. A comparative analysis of the current values of the primary winding of medium voltage instrument transformers with the values of the rated currents of the fuse-links of fuses of various manufacturers presented on the Ukrainian market is carried out. The design features and technical characteristics of fuses for medium voltage instrument transformers have been investigated in order to increase the efficiency of their protection. The advantages and disadvantages of the designs of fuses from various manufacturers have been investigated and it has been established that the design of fuses requires further improvement in order to increase the efficiency of protection of medium voltage instrument transformers. Discussion and prospects for further development. Since in Ukraine, the need for fuses to protect medium voltage instrument transformers is provided mainly by supplies abroad, a promising direction for further development in this direction is the creation of a domestic competitive design of a fuse and its introduction into production.

Legal Media Discourse: Boundaries, Structure, Categories

The paper considers legal media discourse as a discursive format that arose as a result of the interaction of legal discourse and media discourse. The research is aimed at defining the boundaries, structure and categories of legal media discourse. The material of the research are texts of legal media discourse including analytical articles on legal issues, regulatory legal acts, news materials and other genres implemented within the boundaries of the discursive format under study. The research applies methods of scientific description (systematization and interpretation), discursive analysis, as well as the simulation method. The paper provides an overview of research in the field of legal discourse and media discourse, which helps to get closer to defining the boundaries of the format under study, which represents a promising direction for further research. As a result of the systematization of the theoretical and practical material, the boundaries and structure of legal media discourse are determined. It is established that the boundaries of legal media discourse, which is a hybrid discursive formation, lie within the intersection of legal discourse with media discourse. The resulting discursive space has a field structure (core, periphery) and represents a discourse format that concretizes two types of discourse (legal discourse and media discourse) and is represented in turn by different genres. The article gives the description of the categories of legal media discourse, which is based on the model proposed by V. I. Karasik. The paper reveals typical participants of communication, their possible presuppositions, sphere of functioning, chronotope, goals and strategies, genre organization. The author also discusses the issue of implementing the expressive function in legal media discourse through the use of colloquial and obscene lexemes.

Experimental studies of the operation of a frameless building made of thin-gauge structural sections

Light metal structures (LMS) are widely spread in domestic construction industry. A promising direction for the development of LMS includes prefabricated shell structures made of thin-gauge structural sections. The scope and operating conditions of such structures are quite extensive. In this regard, the development of a competent engineering methodology for calculating buildings using thin-gauge structural sections is required. The present paper describes a method for a full-scale testing of a shell building fragment and provides the results of forces and deformations calculated using the experimental model. In addition, an approach to modeling and dimensioning of finite elements for the profiles under consideration is described. The comparative analysis of numerical data and experimental results is performed. The results of the study can be used both for developing recommendations and engineering methods for calculating similar shell buildings and for determining the actual operational scheme for units and elements of the considered structure.

Results: Students note the significant role of end-to-end technologies in professional activities. This is a promising direction for the development of vocational education.

Проблемы иностранных студентов в университетских городах

This paper examines the problems foreign students face in university cities. This aspect seems to be especially important in the formation of a city branding strategy in the context of a “knowledge society”. The university city in this context is considered as an intellectual and social component of the image of the future of the country and a promising direction of the Siberian frontier.

Promising directions of laboratory diagnostics in spores and fitness

The article describes the main biomarkers for determining human adaptation to physical activity. Analyzed modern scientific publications on the criteria of individual tolerance of food products, studied promising directions of personalized correction of the diet. The authors have formed a group of valid (sports-specific) laboratory indicators, it is proposed to pay close attention to the reference values of laboratory equipment that have “their own” norms. A promising direction of laboratory diagnostic work is the formation of reliable and accessible complementary criteria that are at the “junction” of functional and instrumental diagnostic methods. Metabolomics is viewed as a young but highly effective science for detecting highly specific metabolic characteristics of human health. The authors proposed the main directions of scientific research in laboratory diagnostics in sports.

FLAT SIEVE SEPARATORS WITH ANNULAR PNEUMATIC SEPARATION DUCT

The search for the optimal variant of the structural ar-rangement of flat-screen separators by centrifugal-air sepa-rators with annular pneumatic separation ducts is a promis-ing direction in the development of new equipment. This will significantly improve the technological performance of grain cleaning plants. It may be considered a promising direction for such research. Therefore, it is necessary to look for new options for the layout of grain cleaning ma-chines to increase their technological efficiency. Several variants of technological schemes for the operation of ex-isting flat-sieve separators with a centrifugal-air separator with an annular pneumatic separation ducts are proposed. The technological process of the modernized grain clean-ing plant based on the A1-BIS-100 plantis described. The main parameters of the gravity transporting device are de-termined; they fully ensure the operability of the modern-ized plant.

INDIVIDUAL AND GROUP INDICES OF VELVET ANTLER PRODUCTION OF MARALS FOR THE PERIOD OF THEIR ECONOMIC USE

Maral breeding is a promising direction of animal hus-bandry in the Altai Region and the Republic of Altai. Breed-ing of highly productive maral stags is based on the proper organization of breeding work which is not possible without an accurate evaluation of individual and group indices of velvet antler weight. In this regard, the research goal is to study individual and group indices of velvet antler produc-tion of marals for the period of their economic use depend-ing on the age. It was found that the velvet antler weight increased by 6.3 kg over the entire study period, and there was a decreasing tendency of the productive index in thir-teen-year-old marals by 800 g. It was found that in the maral stag herd in 2021, the maral stag born in 2008 with velvet antler weight of 18.8 kg became the record holder. The main criteria for culling were decreased velvet antler production and fatness; the age of those animals was from eleven to fourteen years. In this regard, it was found that individual highly productive thirteen-year-old maral stags could consistently produce high-weight velvet antlers dur-ing the period of their economic use. To improve the quali-tative composition of marals, at breeding time, it is neces-sary to evaluate and select high-productive stags from six to twelve years old individually in dynamics and cull low-productive ones regardless of age.
