(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.
A Study of Correlation Ratios for Low- and High-Density Lipoprotein in Comparison with Antioxidant Vitamins A, E, C at Different Levels of Glycosylated Hemoglobin among Type 2 Diabetes Patients
(WARSE, 2020) Abd Elgadir A. Altoum; Asaad Ma. Babker; Marwan Ismail; Lyashenko, V.
Diabetes is one of the chronic diseases in which the number of patients increases every year. Moreover, diabetes mellitus is a risk factor for the risk for the development of other diseases. Therefore, the number of studies that address various aspects of the diagnosis and control of the processes of diabetes is increasing. Among such studies, an important place is taken by the analysis of the relationship between low and high density lipoprotein and antioxidant vitamins A, E, C. Such an analysis can be done using various analytical methods. This expands medical diagnostics and treatment options for diseases. The study was based on a sample of 300 patients with type 2 diabetes. For analysis, we used: correlation analysis and the wavelet coherence method. The values of wavelet coherence between low and high density lipoprotein and antioxidant vitamins A, E, C for different levels of glycosylated hemoglobin were obtained. This provides an explanation of the differences in the relationship between low and high density lipoprotein and antioxidant vitamins. Also a more consistent dynamics is observed between antioxidant vitamins A, E, C and HDL, taking into account changes in glycosylated hemoglobin levels. This is a key factor in understanding the greater correlations between antioxidant vitamins A, E, C, and HDL.

A Theoretical Interpretation for the Study of Images Processing
(IJARCSMS, 2015) Putyatin, Y.; Lyashenko, V.; Mohammad Ayaz Ahmad; Lyubchenko, V.; N. Ameer Ahmad
In the present article and attempt has been made for the study of image processing, which is an important issue in various systems based on the electronic data analysis. This is also necessary for mankind in the age of modern technology, because it is essential to note systems of computer vision which render the indispensable help to the person in various situations and processes demanding special attention and also speed in decision-making. At the same time among variety of different methods and approaches for image processing it is necessary to allocate methodology of image normalization. The essence of such methodology of image processing consists in indemnification of different geometrical distortions of the input image which have been received a result of registration of the investigated image and its presentation on an input of system of the data analysis, in comparison with some reference picture. On the basis of such approach the work considers geometrical interpretation of the analyzed image of object as a basis of use of the device of the group theory.
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.

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.

Analysis of Trade Trends in Global Non-Precious Metal Markets
(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.

(«European Researcher» (Европейский исследователь), 2013) Kuzemin, A.; Lyashenko, V.; Korovyakovskii, A.; Куземин, А. Я.; Ляшенко, В. В.; Коровяковский, А.
The paper offers the approach to measure of uncertainty estimation in dynamic processes of banks functioning, using statistic data of different banking operations indicators. To calculate measure of uncertainty in dynamic processes of banks functioning the phase images of relevant sets of statistic data are considered. Besides, it is shown that the form of phase image of the studied sets of statistic data can act as a basis of measure of uncertainty estimation in dynamic processes of banks functioning. The set of analytical characteristics are offered to formalize the form of phase image definition of the studied sets of statistic data. It is shown that the offered analytical characteristics consider inequality of changes in values of the studied sets of statistic data, which is one of the ways of uncertainty display in dynamic processes development. The invariant estimates of measure of uncertainty in dynamic processes of banks functioning, considering significant changes in absolute values of the same indicators for different banks were obtained. The examples of calculation of measure of uncertainty in dynamic processes of concrete banks functioning were cited. Основываясь на статистических данных различных показателей банковской деятельности, в работе предложен подход к оценке меры неопределенности в развитии динамических процессов функционирования банков. Для вычисления оценки меры неопределенности в развитии динамических процессов функционирования банков предлагается рассматривать фазовые портреты соответствующих статистических рядов данных. При этом показано, что основой рассмотрения предполагаемой оценки меры неопределенности в развитии динамических процессов функционирования банков может быть форма фазового портрета исследуемых статистических рядов данных. Для формализации формы описания фазовых портретов исследуемых статистических рядов данных предложен ряд аналитических зависимостей. Показано, что предложенные аналитические зависимости учитывают неравномерность динамики значений исследуемых статистических рядов данных, что является одним из видов проявления неопределенности в развитии динамических процессов. Получены инвариантные оценки меры неопределенности в развитии динамических процессов функционирования банков, учитывающие значительные отличия в абсолютных значениях одних и тех же показателей для разных банков. Приведены примеры расчета оценки меры неопределенности в развитии динамических процессов функционирования реальных банков.
Assessment Dynamics the Development of Financial Markets in the UK and Japan in the Context of COVID-19 Pandemic
(IJAMR, 2022) Lyashenko, V.; Bitner, I.; Bilotserkivskyi, O.
The negative dynamics of the spread of the COVID-19 pandemic affects all areas of daily and economic activity. At the same time, the degree of such influence is largely determined by the continuity of the movement of various financial flows, the possibility of their rapid renewal in cases of emergency slowdown or interruption of movement. For the analysis of the movement of financial flows, it is important to study the development of financial markets. It is important to carry out such an analysis from the point of view of different segments of the financial market. At the same time, it is also necessary to take into account the general trend in the development of the financial market, the relationship of its individual segments. This can be done based on the analysis of the relevant stock indexes. The paper considers the dynamics of the real values of stock indices, which reflect the dynamics of the development of individual sectors of the financial market. The paper also takes into account the aspects of conducting a comparative analysis, which allows us to identify common patterns. To do this, we consider the values of the UK and Japan stock indices. To conduct a comparative analysis, we use the methodology for constructing wavelet coherence estimates. The paper presents many graphs and charts for specific real data. This allows you to understand the logic of the study and the results obtained.
Assessment Relationship Between Components of the World's Leading Stock Indices in Reflection on the World Financial Market Dynamics
(IJAMSR, 2021) Lyashenko, V.; Sergienko, O. A.; Bilotserkivskyi, O. A.
The development of the global economy presupposes the stable functioning of all its constituent parts, institutions, and markets. Among such markets of the global economy, a special place is occupied by the financial market, which is able to redistribute financial resources. However, such redistribution must be protected from various risks, unfavorable development of negative situations. To solve such problems, the concept of stock indices is used, which reflects the dynamics of price changes for different groups of securities. Knowing the dynamics of the values of stock indices, one can analyze and predict the development of the financial market as a whole. It is also necessary to take i nto account the relationship of stock indices and the relationship between the components of various stock indices. Based on this, the paper examines a qualitative assessment of the relationship between the components of the world's leading stock indices in reflecting the dynamics of the world financial market. It is proposed to consider such a qualitative estimate taking into account the wavelet coherence. To this end, the paper proposes a general approach to considering a qualitative assessment of the relationship between the components of the world's leading stock indices. The paper considers real data in the context of various world stock indices, presents research results, and draws general conclusions.
