AI-Driven Digital Concept Maps in Learning Environments: Empirical Insights from Student Use
(2025-12-16) Tytenko, Sergiy; Papkovych, Yehor; Zhak, Mariia; Shkelebei, Sofiia; Vasyliev, Oleksandr
This study explores the integration of AI-powered, ontology-based interactive concept maps into a university programming course to support student learning and includes a comparison of these maps with AI-generated instructional text materials. As part of the “SDT 100: Principles of Programming with Java” course at American University Kyiv, foundational instructional materials were generated using GPT-4o and formalized into an ontology via the Semantic Portal platform. The platform then automatically generated interactive concept maps, with each node linked to structured concept descriptions. These maps were used alongside AI-powered text lectures, providing students with an alternative to linear instructional content. To assess pedagogical relevance, students were asked to provide qualitative feedback on the perceived usefulness of the concept maps. The findings suggest that such maps are particularly effective for content review and understanding conceptual relationships, serving as a valuable complement to traditional text-based materials. The study provides empirical evidence on the instructional potential of AI-powered, ontology based concept maps and outlines future directions for enhancing their automated generation using large language models.

A SOFTWARE SOLUTION FOR INTELLIGENT FAULT DETECTION IN WHEEL BEARINGS
(Manuscript, 2025-01-23) Glugovskiy, Glib
Wheel bearings are critical components in machinery and vehicles, and their failure can lead to costly downtime and safety risks. This project focuses on the research, development, and implementation of an intelligent software solution for fault detection in wheel bearings. By combining advanced signal processing techniques and machine learning, the solution enables early and accurate fault diagnosis efficiently for all users.
The software incorporates Fast Fourier Transform (FFT) for feature extraction and Self-Organizing Maps (SOMs) for clustering and fault classification, achieving high accuracy in detecting bearing defects. This approach marks a significant advancement in the fields of machine maintenance and fault diagnostics by offering a more precise and efficient method for identifying defects in wheel bearings.
A key aspect of the project involves the development and training of a SOM model. This model is specifically designed to analyze patterns in the cyclostationary signal data, enabling the accurate identification of potential bearing faults. The SOM model, along with the other signal processing and machine learning components, is integrated into a robust software application. Built using Django and React.js for the web interface and enhanced with Rust libraries for computational efficiency, this solution presents a novel integration of traditional web technologies with modern performance optimization techniques.
MULTIMODAL RETRIEVAL AUGMENTED GENERATION SYSTEM
(Manuscript, 2025-01-23) Yuvzhenko, Denys
This study presents an asynchronous, web-based Retrieval-Augmented Generation (RAG) system that integrates multimodal inputs (text, images, tables) to enhance information retrieval and generation in various contexts. The system is developed in Python and hosted on AWS, combining Chroma DB for vector storage and Anthropic’s Claude-3-Haiku LLM model, which is accessible via AWS Bedrock. By leveraging modern cloud capabilities, the solution scales efficiently and handles diverse data modalities in real time.
Through systematic experiments, this project highlights the effectiveness of multimodal embedding techniques for refining retrieval accuracy and providing context-aware responses. The architecture’s modular design supports seamless feature integration, making it adaptable for different use cases such as customer support, educational tools, and content creation. Key findings emphasize the role of vector databases in dynamic information updates and confirm that large language models, when appropriately curated and grounded, can produce high-quality, relevant outputs
