    Mutual Dynamics of Certain Types of Bitcoin: Data from Wavelet Coherence
    (IA-ESTE, 2021) Lyashenko, V.; Bilotserkivskyi, O.; Pyvavar, I.; Kots, H.
    Unconventional methods of analysis are a good tool for studying new trends and phenomena. One of these objects of research is the cryptocurrency market. The paper shows the possibility and feasibility of applying the ideology of wavelets to analyze the dynamics of prices for cryptocurrencies. For this, the methodology of wavelet coherence is used. This methodology has been applied to various cryptocurrency pairs. The calculation results for real data are presented. It is shown that the results obtained agree with the theoretical conclusions and research results of other authors.

    Phase Portrait Models as a Tool for Analyzing Banking Activities
    (IJAMSR, 2023) Baranova, V.; Kots, H.; Rudenko, D.; Lyashenko, V.
    Banking and the functioning of banks is one of the active areas of research. Banks play an important role in the development of the country, the functioning of individual business entities and the economy as a whole, and the satisfaction of the economic needs of certain individuals. At the same time, it is important to emphasize the complexity of carrying out an appropriate analysis. This is due to the need to consider interrelated random processes that occur simultaneously. Therefore, it is important to use adequa te models that contribute to the solution of the tasks. Such models should not only adequately describe the situation, obtain the necessary results for decision-making, but also adequately interpret the processes that we are studying. Based on this, we consider the phase portrait model as a tool for analyzing banking activity. We give a general description of such a model and show its application to real data. We also consider 2D and 3D visualization of such a data analysis model. The paper summarizes some results of banking analysis modeling. The paper presents various graphs of the analysis that we carry out. This helps to understand the logic of the study and the results obtained.
