    Fall detection system for old people
    (Igor Sikorsky Kyiv Polytechnic Institute, 2025) Jiayi Liu; Berdnyk, Yurii
    This thesis project proposes a real-time human fall detection system based on YOLO (You Only Look Once) target detection and MediaPipe posture estimation. As the trend of population aging gradually worsens, the problem of elderly falls has become an important issue of social concern. Traditional fall detection methods have problems such as response delay and inconvenience in wearing. This study combines the efficient target detection capability of YOLOv8 and the precise posture estimation technology of MediaPipe to design a monitoring and real-time feedback fall detection system. The system combines the YOLOv8 target detection algorithm and MediaPipe human posture estimation technology, and builds a friendly user interaction interface through the PyQt6 framework. The system adopts a multi-threaded architecture to achieve real-time processing and display of video streams. In the human body detection link, the system uses the YOLO model to quickly locate the human target in the picture; uses MediaPipe to extract the key points of the human body for posture analysis, and designs a fall judgment algorithm based on the characteristics of the torso angle, the height difference between the head and ankle, and the relative position of the shoulder and hip. The experimental results show that the system shows high detection accuracy and real-time performance under various environmental conditions, and the average detection accuracy can reach 90%. This study provides an effective fall detection solution for smart homes, nursing homes, medical monitoring and other fields.

    Messaging System for Foreign and Local Students
    (Igor Sikorsky Kyiv Polytechnic Institute, 2025) Omar Youssef; Berdnyk, Yurii
    This diploma project presents the comprehensive design, development, and evaluation of a multilingual, web-based messaging and blogging system specifically tailored to improve communication and cultural exchange between foreign and local students in academic institutions. Recognizing the growing need for inclusive, accessible, and user-centric digital platforms in internationalized university environments, the proposed system integrates both private and public communication channels while supporting blog-style content creation to foster engagement, knowledge sharing, and peer-to-peer support. The system introduces a broad feature set that includes user registration and authentication, multilingual user interface switching (supporting English and Ukrainian), real-time public chat functionality, post creation and categorization, keyword-based filtering, image embedding, and intuitive user profile management. Furthermore, an admin moderation dashboard ensures content quality and platform integrity, offering tools for user oversight, content review, and system analytics. From a technical standpoint, the platform was implemented using the Pythonbased Flask web framework, alongside HTML5, CSS3, JavaScript, and Jinja2 templating for dynamic frontend rendering. Data storage and interaction logic rely on structured JSON files, chosen for their simplicity, lightweight nature, and ease of manipulation during early-stage prototyping and student-led development. The system architecture reflects a clean MVC (Model-View-Controller) pattern, promoting maintainability and future scalability. This report delivers a detailed exploration of the project's development lifecycle, beginning with the problem statement and motivation, followed by a literature review that analyzes existing solutions in the domain of multilingual education technology and student support systems. The implementation section outlines the backend logic, frontend components, and UI/UX design decisions. Testing procedures are described with emphasis on usability, functionality, and language rendering accuracy. A discussion on project challenges and limitations is also presented, followed by proposals for future enhancements such as database integration, mobile responsiveness, offline functionality, and AI-based translation or moderation tools. By addressing critical barriers to communication among students from diverse linguistic and cultural backgrounds, the developed system not only fulfills academic objectives but also aligns with broader institutional goals of inclusivity, digital transformation, and intercultural integration. This work adheres to the methodological and formatting standards specified by the Department of Computer Engineering and contributes meaningfully to the ongoing discourse on educational technology in multicultural settings.

    Mobile Application for Supporting the Religious Practices of Muslims
    (Igor Sikorsky Kyiv Polytechnic Institute, 2025) Darwish Jamil Mohammad Jamil; Berdnyk, Yurii
    This paper is devoted to the development and implementation of a cross-platform mobile application for the Muslim audience, which provides support for daily spiritual life in accordance with the requirements of Islamic tradition. The primary objective of this study is to develop a tool that can accurately calculate the time for the five obligatory prayers, considering the user's geographical location and the selected calculation method. Moreover, the application incorporates modules that facilitate the determination of the direction of the Qiblah through the utilization of the device's sensors. It also encompasses the integration of the Islamic calendar, access to the text of the Qur'an and hadith in multiple languages, a digital tasbih counter, a notification system, and motivational daily reminders.
