Документ Application of optical character recognition and machine learning technologies to create an information system for automatic verification of offline testing(Національний технічний університет "Харківський політехнічний інститут", 2024) Ziuziun, Vadym Ihorovych; Petrenko, Nikita AndriiovychDuring the learning process in any field, testing and monitoring the knowledge of students or other learners is an essential part. The purpose of this research was to develop an information system (web platform) that simplifies the offline test grading process using optical character recognition technologies powered by machine learning algorithms. The object of this research is the processes and functionality involved in creating an information system for the automated grading and evaluation of offline tests. The developed system can recognize handwritten text from photos, create an array of responses, and compare them to the answers provided by the teacher. This approach significantly reduces the time teachers spend on grading tests. For user convenience, a minimalist interface was created, granting access to all main system functions with intuitive controls. A detailed description of the developed algorithms and machine learning models is provided.Документ Software development and research for machine learning-based structural errors detection in BPMN models(Національний технічний університет "Харківський політехнічний інститут", 2024) Kopp, Andrii Mykhailovych; Orlovskyi, Dmytro Leonidovych; Gamayun, Igor Petrovych; Sapozhnykov, Illia VitaliiovychThe most important tool for process management is business process modeling. Business process models allow to graphically represent the sequences of events, activities, and decision points that make up business processes. However, models that contain errors in depicting the business process structure can lead to misunderstanding of a business process, errors in its execution, and associated expenses. Thus, the aim of this study is to ensure the comprehensibility of business process models by detecting structural errors in business process models and their subsequent correction. During the analysis of the Business Process Management (BPM) lifecycle, it was found that the created business process models do not have a stage of control for the presence of errors in them. Therefore, the paper analyzes and improves the BPM lifecycle using the proposed approach. In the improved BPM lifecycle, it is proposed to take into account the correctness validation stage of business process models using the developed software.Документ Analysis of the applications of the data-driven approach in evaluating the thermal-physical properties of composites(Національний технічний університет "Харківський політехнічний інститут", 2024) Lavshchenko, Ruslan Rovshan ohly; Lvov, Gennadiy IvanovychThis research analyzes the potential and prospects of a data-driven methodology for examining the thermo-physical properties of composite materials. The analysis examines fundamental principles and advanced machine learning approaches utilized in materials science, highlighting their ability to improve the knowledge, optimization, and overall quality of composite materials. This study thoroughly examines the application of neural networks in forecasting thermal characteristics, highlighting its predictive skills and potential to transform the analysis of thermal properties in composite materials. Additionally, the research underscores the growing reliance on big data analytics in addressing complex challenges in material behavior, particularly under variable environmental conditions. A comparison assessment is performed between the data-driven methodology and traditional analytical methodologies, emphasizing the distinct advantages and drawbacks of each. This comparison elucidates how data-driven methodologies can enhance and refine the precision of thermo-physical analysis. The convergence of machine learning and material science is shown to not only facilitate more accurate predictions but also reduce experimentation time and costs. The report also delineates contemporary techniques for measuring and forecasting the thermo-physical properties of composites, emphasizing the advancements in new technologies in recent years. The function of computational tools and computer technology is elaborated upon, especially with the modeling of thermo-physical properties and the simulation of production processes for composite materials.
