    APPLICATION OF OPENAI API FOR SEMANTIC CONTENT ANALYSIS IN INTELLIGENT E-LEARNING SYSTEMS
    (2024) Rybak, Mykola
    The thesis aims to describe the practical aspects of using OpenAI API in intelligent e-learning systems. The proposed work contains three main parts. The first part covers a background overview, theoretical aspects of a Large Language Model (LLM), transformer-based Natural Language Processing (NLP) architecture description, and use cases of different transformers. Introduces the term semantic unit and defines its main elements and connection with the capstone project. The second part concerns the rationale of the chosen model’s type for the capstone project and its description and implementation. This part covers requirements for the capstone project, C4 architecture diagrams, an overview of essential modules, libraries, and code examples of the implemented solution leveraging OpenAI API. The final part demonstrates further research on architecture improvements for better semantic content analysis and interaction with intelligent e-learning systems, including a combination of encoder-decoder and embedding models in the solution.

    ExoCoDe: MODELING TRANSITS EVENTS VIA STATISTICAL AND MACHINE LEARNING TOOLS
    (2024) Karakuts, Denys
    This capstone project uses statistical and machine learning algorithms to detect exocomet transits in TESS telescope data. Exocomets, distinguished by their unique, asymmetric light curves, present a detection challenge due to their subtle signatures compared to planetary transits and light intensity. We develop a framework that integrates data preprocessing, feature extraction, visualizations, statistical methods, and machine learning regressors to characterize these transits efficiently. The project is built upon the existing progress of astrophysical research. It aims to enhance our understanding of exocometary activity, uncovering the potential of machine learning and statistical analysis in astronomical data interpretation.

    COMPARISON OF ARCHITECTURAL PATTERNS WITHIN iOS APPLICATIONS
    (2024) Skrypchenko, Mykyta
    This work delves into the strategic selection of software architecture for iOS applications, underscoring the alignment of architectural decisions with specific project constraints and goals. Initial discussions centered around the challenges in using software metrics to compare various iOS architectures, leading to the proposal of a simplified framework aimed at aligning architectural choices with defined business objectives. The paper details the process of evaluating different architectural patterns — MVC, MVVM, VIPER, and TCA — considering these constraints and goals. This work contributes to the field by providing a practical example of how architectural decisions can be tailored to specific project constraints and goals, offering insights that can be valuable for software architects and developers working on similar Swift application projects.

    HONEYCOMB MONOLITH: HEXAGONAL MODULAR PATTERN FOR AGILE MICROSERVICES EVOLUTION
    (2024) Shablii, Taras
    This thesis explores the architectural dilemma faced by startups and greenfield projects: choosing between monolithic and microservices structures. It addresses the gap in research on evolutionary monolithic architectures, introducing the Honeycomb Monolith pattern. This pattern combines Domain-Driven Design with Hexagonal Architecture to create modular monoliths poised for smooth transition to microservices. The effectiveness of the Honeycomb Monolith is demonstrated through the Opora application case study. This implementation validates the pattern viability, showing a seamless migration with minimal impact on the core domain logic. Challenges like model duplication and database management complexities are also identified, underscoring the need for strategic planning in architecture design. Concluding with future research directions, the thesis positions the Honeycomb Monolith as a viable solution for startups and an intermediary step for existing projects transitioning to microservices. This work contributes to the software architecture field, offering a novel solution that balances initial development efficiency with long-term scalability.

    QUANTITATIVE RISKS ANALYSIS ON SOFTWARE PROJECTS USING THE MONTE CARLO METHOD
    (2024) Oliyarnyk, Yuriy
    Software projects are crucial for creativity, productivity, and organizational performance. However, their complexity can lead to risks and failures. Despite modern project management tools improving success rates, significant investment waste and project failures persist. In 2020, 11.4% of investment was lost due to poor project performance, and in 2021, 33% of IT projects failed, resulting in significant budget losses. As organizations enter 2022, challenges in big data, analytics, and AI projects are increasing, highlighting the need for a paradigm change in project management techniques. The Monte Carlo approach, a quantitative risk analysis technique, is gaining popularity to reduce uncertainty in software projects and provide more reliable estimations. The current implementation uses Jupyter Notebooks technology and decreases a steep learning curve for users.
