A Robo-hand prototype design gripping device within the framework of sustainable development

(Discovery Scientific Society, 2023) Al-Sharo Yasser; Abu-Jassar Amer; Lyashenko, V.; Yevsieiev, V.; Maksymova, S.

In the modern world, the rate of science development is far ahead of the rate of latest research results implementation. For research results implementation, it is necessary to develop more and more new engineering solutions. Without them, all scientific developments will remain "on paper". At the first stage of making such solutions, it seems advisable to create prototypes for the systems that are under development. Such prototypes allow you to quickly make a working system with little effort and to test it for its performance, and to identify errors that need to be corrected. In the paper, the authors propose a robo-hand prototype design development. There was selected a necessary equipment and there were developed all the schemes required. In this work, an assembly of a gripping device prototype is presented.

Access Control to Robotic Systems Based on Biometric: The Generalized Model and its Practical Implementation

(INASS, 2023) Abu-Jassar Amer Tahseen; Attar Hani; Lyashenko, V.; Amer Ayman; Sotnik, S.; Solyman Ahmed

The paper presents a generalized system's structural scheme and components for monitoring and controlling access to robotic systems based on biometric data for decision-making. Mathematical decision-making models for choosing the best alternative based on fuzzy sets are proposed. The fuzzy analytical hierarchy process determined weights of 6 criteria (for k1 criterion weighting factor is equal to 2.2; for k2 criterion – 1.8; for k3 criterion – 0.6; for k4 criterion – 0.6; for k5 criterion – 0.6; for k6 criterion – 0.2, that is, most weighty would be k1 – recognition accuracy) against which the best option was evaluated. Thus, during evaluation of alternative on six criteria it was obtained that t alternative X1 (face recognition in full-face), will have the key value of embership function of resulting fuzzy set alternatives with ideal value of integral criterion, equal to 0.53, and as result, implemented rational choice, taking into account given criteria. The difference is that we have introduced such criteria as anti-spoofing. The access control system for robotic systems works in real-time. It is implemented based on an algorithmic decision -making complex, which includes two-factor authentication to increase security: registration involves entering emp loyee data from the keyboard (password, login, surname, first name, position) and physiological uthentication (identification by face). Face detection is proposed to be implemented on several images: face, profile, face, and profile in the mask. A distinctive feature of our development is that often, a main requirement for "access control systems with facial identification" is the frontal location of the face relative to the camera; in our case, the image of the face at an angle was added.

Analisys of teaching elements on technical and mathematical disciplines in modern distance education

(Technology Audit and Production Reserves, 2021) Biziuk, A.; Biziuk, V.; Shakurova, T.

The object of research is the quality of teaching technical and mathematical disciplines in modern distance education. One of the most problematic areas is communication, dialogue between a teacher and a student, per-sonality problems in the teacher-student dyad, and the effectiveness of feedback. The idea of distance learning, obviously, is that the interaction between teacher and student takes place in a virtual space. The more efficiently this interaction is built by using a variety of techniques, methods, the better a teaching process. Distance teaching is essentially a person-centered form of education. This is a separate modern educational technology that provides a choice for the teacher, the ability to select educational material depending on the information needs of students. In the course of the study, the main possibilities for improving the effectiveness of feedback between the student and the teacher and the forms of implementing such communication were considered. The organizational and pedagogical conditions for the use of the system of certain elements of distance learning in the process of vocational training have been substantiated. Modern information technologies and innovative teaching methods in training specialists are described. It is proposed to use more actively such elements as an interactive whiteboard, interactive processing of students’ statements during a survey, both in the form of tests or a forum, and in the form of a «word cloud». The use of these interactive elements has proven itself in practice. As a tool for objective assessment of the level of feedback, a comparative analysis of statistical data is pro-posed, which concerns the distribution of marks at the beginning and at the end of the distance learning course. This data can also be interpreted as an indicator of the quality of teaching. In particular, the analysis of school preparation of students for mastering mathematical disciplines in higher education was carried out. Comparative analysis substantiated, in particular, the need for additional classes for students with poor preparation.

Analysis of Existing Infliences in Formation of Mobile Robots Trajectory

(International Journal of Academic Information Systems Research, 2022) Sotnik, S.; Lyashenko, V.

The work considers and analyzes three main ways of forming trajectory of movement: coordinate trajectory and vector. The choice of description method depends on conditions of specific problem. The specificity of different type’s movement of robots is analyzed: wheeled, tracked and walking. One of features in formation of movement trajectory in space with dynamic obstacles is speed. Thus, analysis of impacts is especially important for those robots that are able to achieve significant speeds and accelerations, as well as for robots characterized by large load capacity, while dynamic effects are associated with significant masses in structural elements. Today, there is no unified universal approach to constructing trajectories in environment with obstacles. The analysis showed that formation of rational trajectory taking into account: length and smoothness of trajectory; nature of workspace an d map of area; safety – distance to obstacles; type of mobile platform (method of moving robot) will ensure correctness and conflict-free trajectory.

(International Journal of Academic Multidisciplinary Research, 2023) Samorodov B.; Zastola Y.; Lyashenko V.

Analysis and comparison are research tools that allow you to consider various trends and make the necessary informed decisions. Currently, much attention is paid to IT technologies that contribute to the development o f business entities, the introduction of new processes, and the formation of an innovative paradigm. This allows us to talk about the importance of IT companies in the formation of sustainable economic development, relationships between contractors and par tners. Most of these companies are listed on the stock market where their securities are located. The display of such an appeal is the dynamics of prices for the relevant shares. The paper considers quotes for shares of leading high-tech companies. To do this, we use standard statistical methods, a quantitative comparison procedure, and wavelet theory. As a result of the analysis, we obtained various dependencies and data estimates, which are presented in the form of stock prices. The findings allow us to u nderstand the dynamics that exist in the IT companies market. We can also develop approaches to the choice of investment strategies when implementing innovative solutions. The article contains many figures and diagrams. This helps to understand the progres s of the research.

(IJAMR, 2022) Zeleniy, O.; Lyashenko, V.; Shapran, O.

International trade occupies one of the key places in the system of economic relations, the development of various sectors of the economy and society. This is achieved through the organization and functioning of various types and types of markets t hat allow us to implement and maintain the necessary economic relations. This, ultimately, determines the feasibility of conducting ongoing research aimed at analyzing trade trends in world markets. Such an analysis can be carried out both from the point of view of the development of market relations in general, and taking into account the specifics of the functioning of individual market segments. Among the many segments of the world market, we single out the base metals market. The base metal market is a part of the commodity market where primary goods are traded. This makes this market special and attracts close attention. We consider the statistical characteristics of futures for various types of non-precious metals; we present the dynamics of such quotes. To analyze the mutual influence of individual quotes on futures, wavelet coherence estimates are used in the work. The paper presents a number of graphs and diagrams that help to understand the logic of the study, the reliability of the results.
