    Development of the system for plagiarism checking of Ukrainian texts
    (2022) Bikchentaev, Mykola; Hlybovets, Andrii
    So, the aim of this work is to review two machine learning models called BERT and Word2Vec, determine how can they be used in plagiarism detection, and develop an application where users can check texts for plagiarism.

    Distributed system technical audit
    (2020) Zhylenko, Oleksii; Hlybovets, Andrii
    In this coursework will be defined what is distributed systems, review Monolithic, Microservice and serverless architecture. Also, we will deep dive into technical audit process, specify what aspects of system must be considered during audit. Then will iterate over checklists item in order to provide guidelines based on best practices in industry that helps to prepare for system audit.

    Emitter Position Estimation Using Time Difference of Arrival
    (2022) Musiiaka, O.; Hlybovets, Andrii
    As a result of this work, the estimator convergence speed was improved by using a local linear transform. This new approach can be considered an adaptation of the Newton-Raphson algorithm with the Hessian matrix replaced with a statistically approximated value that guarantees the algorithm convergence and reduces the amount of computation. Performance testing of the optimization algorithms has shown that the proposed algorithm outperforms the steepest gradient descent 28.2 times and “momentum” modification 7.8 times on the CPU implementation.

    Investigation of the relationship between software metrics measurements and its maintainability degree
    (2020) Shapoval, Oleksandr; Hlybovets, Andrii
    The goal of this thesis was to practically learn methods of empirical engineering software, algorithms for data collection and data analysis. Results include software measurement, analysis and selection of direct and indirect metrics for research and identification of dependencies between direct and indirect metrics. On the basis of received result were built dependencies between software metrics and software expertise properties. Metrics and properties selected by individual variation. Relationship between metric and expertise includes building direct relationships between the metric and expertise, indirect metrics and expertise. Additionally, was determined whether they have common trends of the relationship between those direct metrics and expert estimates, indirect metrics and expert estimates.

    Statical and Dynamical Software Analysis
    (2020) Sosnytskyi, Serhii; Hlybovets, Andrii
    Development of software with build in quality has become an important trend and a natural choice in many organisations. Currently, methods of measurement and assessment of software quality, security, trustworthiness cannot guarantee safe and reliable operations of software systems completely and effectively. In this coursework overviewed statistical and dynamical software analysis methods, main concepts and techniques families. The second part of the coursework is dedicated software analysis including solutions for continuous analysis in agile development life cycle.
