Публікація 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.Публікація Comparative Assessment the Dynamics of Stock Indices in France, Germany, Italy and Great Britain(IJAAFMR, 2021) Lyashenko, V.; Baranova, V.; Novikova, T.Comparative assessment is one of the tools for data processing and analysis. This assessment allows you to assess the effectiveness of interaction and direction of development between the objects that are compared. Among the various spheres of scientific and applied research, the analysis of the development of economic relations deserves special attention. This is necessary to understand the dynamics of general economic development, the functioning of economies in difficult conditions (for example, in the context of a pandemic). The object of such a study can be various financial flows. The generalizations of the movement of financial flows are stock indices. We examined the relationship between the dynamics of stock indices in France, Germany, Italy and the UK. We reviewed the most significant stock indices in each of the countries. This makes it possible to assess the economic development of such European countries, their mutual influence on each other, to show the level of interconnection. For this we use the ideology of wavelet analysis. Based on wavelet coherence, we examined est imates of the relationship between stock indices in France, Germany, Italy and the UK. The results of calculations for real data are presented. The results show the real level of economic interconnection between the countries we study. These results are based on the real dynamics of stock indices. This allows making decisions for the development of mutual economic ties between European countries, between European countries and the rest of the world.Публікація Dynamic and Static QR Coding(IJAER, 2022) Deineko, Zh.; Sotnik, S.; Lyashenko, V.This work is overview in field of dynamic and static QR-coding. The main attention is paid to peculiarities of using dynamic and static QR codes. The paper proposes classification of QR-codes. Key code characteristics that you should pay attention to when selecting and writing code have also been identified. A comparison of dynamic and static QR-coding is given.Публікація Dynamics of Changes in Commodity Indices for Commodities: Wheat, Corn, Soybeans, Sugar, Cocoa(IJAAR, 2022) Lyashenko, V.; Serhiienko, O.; Bilotserkivskyi, O.Commodity indices determine the weighted price of various groups of goods. At the same time, the dynamics of such indices reflects the dynamics of prices for the corresponding goods. In turn, commodity indices are interconnected with the dynamics of indices, both the securities market and the general world market. An analysis of this relationship helps to understand the dynamics of the functioning and development of individual market segments, the economy as a whole, and various business entities. An important aspect of this analysis is the assessment of relationships, primarily between groups of goods that are placed on the commodity market. Based on this, the paper considers the main aspects of the analysis of the dynamics of commodity indices, presents graphs of commodity indices for individual groups of goods, and considers the main statistical characteristics of such data. To assess the mutual analysis of the dynamics of changes in commodity indices, the wavelet coherence methodology was used. This methodology makes it possible to evaluate the mutual dynamics of commodity indices over different time horizons. We can better understand the dynamics of the relevant relationship, which is important for making investment decisions. Such assessments are also important for making decisions about interaction in different segments of the world market or the stock market. Some results of assessments of such a methodology are presented. The paper presents a lot of factual material, which helps to understand the logic of the study.Публікація Mutual Analysis of the Dynamics of Development of the Banking Sectors of Key Countries in Europe, Asia and America(IJAAFMR, 2023) Lyashenko V.; Bitner Irina; Ponomarenko O.The banking sector plays an important role in the economy and development of every country. The banking sector is an important segment of the financial market. Banks normalize and ensure the continuity of the movement of various financial flows between different economical agents. At the same time, banks play an important role in international trade. Banks contribute to ensuring the parity of currency quotes, mutual settlements between countries, and support the movement of financial flows at the international level. For such provision, an important point is the mutual analysis of the banking systems of different countr ies. One of the indicators of the functioning of different banking systems are the corresponding stock indices. We consider the dynami cs of changes in a number of such stock indices for some countries in Europe, Asia and America. We also consider some statistical characteristics of the dynamics of changes in the corresponding stock indices selected for analysis. This allows a better understanding of the functioning and development of the respective banking systems. For analysis, we use the wavelet ideology . We consider the corresponding wavelet coherence estimates. The paper presents a series of graphs and charts that allow you to understand the results of this study. The results obtained allow us to form appropriate strategies for entering the internati onal banking market.Публікація Publishing books in Braille in Ukraine: problems and achievements(ХНУРЕ, 2020) Chebotarova, M.; Silchenko, V.; Chebotarova, I.The features of preparing books in Braille are considered. The problems of providing the blind and visually impaired with inclusive literature and the prospects for the development of the braille book market in Ukraine are analyzed.Публікація Visual saturation: analysis of advertising in social networks(ХНУРЕ, 2020) Gutiérrez, Venus Maribel Gutiérrez; Gurieva, N.We are so saturated with visual information that now it’s a challenge for designers and artists to find a balance between amount of the information and complexity of the message that is transmitted through advertising. Social media advertising are advertisements served to users on social media platforms. Social networks utilize user information to serve highly relevant advertisements based on interactions within a specific platform, but at the same time, because of the low quality of such advertising, users are getting oversaturated with this information that becomes unpleasant and generates user “blindness”.Публікація Wavelet Coherence as a Digital Visualization Tool for Comparing Economic Data Dynamics(IJAISR, 2022) Vasiurenko, O.; Lyashenko, V.Analysis is one of the tools for studying data of various nature. Among the variety of such data, we single out economic data. The analysis of economic data is an important aspect in the study of various phenomena and processes that are associated with the study of economic dynamics. At the same time, an important point of such an analysis is the comparison of the dynamics of economic data. This is important both for understanding the processes that take place and for making appropriate management decisions. At the same time, for a more complete understanding of various aspects of the analysis, it is necessary to visualize the relevant data. Such visualization helps to better analyze the comparative dynamics between the various data that we study. It also allows you to understand hidden relationships .To implement the stated task, we propose to use the methodology of wavelet analysis. Among the methods of wavelet analysis, we single out wavelet coherence. The paper considers various aspects of using wavelet coherence for digital visualization of economic data. Possibilities of conducting a comparative analysis with the help of wavelet coherence are shown. Various graphs and examples for real data are given. This allows you to better understand the consideration of the issues raised.
