Project Safety Management Systems of Students with 3D Game Development
(2021-08-03) Sivakovska, Olena; Rudynets, Mykola; Yashchuk, Andrii; Redko, Rostyslav; Zabolotnyi, Oleg
One of the main directions of the modern state development is the sphere of ensuring the security of the population. New ways to improve the system of safety measures for participants in the educational process in emergencies, which provide increased stress resilience of students and provide support at a high level of their knowledge and skills to act in extreme conditions were been proposed. One of the ways is a project of training in a virtual environment close to real conditions. It is proposed, for the first time, to develop a training-game 3D simulator for psychological preparation and training of students to act in emergencies, using various functions of modeling possible emergencies. The developed software will help to increase the level of socioeconomic protection of students through the game in a 3D simulator, which will be offered to students as homework or before lessons, or as training behavior in emergencies of different nature and under different conditions. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
Performance Comparison of Low-Density Parity-Check (LDPC) Codes for Reliable Communication in Noisy Channels
(Tampere: IEEE, 2024-04-24) Yashchuk, Andrii
Background: With significant improvements in communication systems, especially in the context of emerging smart cities, data dependability over noisy channels has become critical. Low-Density Parity-Check (LDPC) codes have gained popularity because to their large error correcting capabilities, which have even approached the Shannon limit, making them indispensable in current communication systems.Objective: The purpose of this article is to conduct a thorough examination of the performance of LDPC codes, with a focus on their effectiveness in noisy communication situations. Understanding the capabilities of LDPC in error correction, decoding complexity, and throughput efficiency across various setups and circumstances is the goal.Methods: A variety of LDPC code configurations, including specialized configurations such as turbo-coded LDPC and finite geometry-based LDPC codes, were investigated. Their performance was evaluated using simulations under various signal-to-noise ratio (SNR) settings, offering a realistic perspective on how they will behave in real-world communication scenarios.Results: Preliminary data indicate that LDPC code configurations vary in performance. The current study focuses on the trade-offs of various arrangements, stressing their unique strengths and disadvantages. This comparison analysis gives a road map for choosing the best LDPC code for certain communication applications, which is especially important for urban areas on their digital transformation path.Conclusion: In the smart cities, LDPC codes offer tremendous potential to improve the reliability and efficiency of communication networks. Understanding their intricacies, strengths, and trade-offs may help influence communication strategy choices, resulting in more connected, efficient, and sustainable urban ecosystems. © 2024 FRUCT.
Development of a system for predicting failures of bagging machines
(2025-12-20) Huliieva, Nataliia; Lishchyna, Nataliia
The reliability and effective operation of machines is a pressing problem for every enterprise, which requires labour intensive systematizationof production processes. The goal is to develop an algorithm and a system for predicting failures of packaging machines based on the analysisof operational indicators. The scientific novelty lies in the integration of statistical data to assess the efficiency of machine operation and predict possible failures, which allows significantly improving maintenance processes and reducing the risks of unforeseen breakdowns. The practical valueis the development of a forecasting system that collects the necessary statistical data and performs forecasting. Based on the collected data, an assessment of the efficiency of work and forecasting of possible failures is carried out. The forecasting system is demonstrated on the example of packaging machines LEMO INTERmat ST-SA 850 of "Tatrafan" LLC. Two research methods were used: calculation (mathematical) and forecasting system (least squares method). The forecasting system provides two ways of presenting data: tabular and graphical. Tabular presentation of data allows filtering information according to various criteria, while graphical display is implemented in the form of diagrams showing the operating time and downtime of machines.The main results are the determined range of probable failure of LEMO INTERmat ST-SA 850 packaging machines, which lies in the range from 9090.5to 12736.5 hours of operation and almost coincides with the manufacturer's warranty period. With timely maintenance, it is possible to increase the lower limit of this interval.

(2022-09-26) Satsyk, Viktor; Lishchyna, Nataliia; Khrystynets, Nataliia; Gumeniuk, Larysa; Korobchuk, Liudmyla
In this paper we develop system approach for obtaining, analysing and managing the agronomic parameters of the soil based on software and hardware IT-complex. The developed tool Soil Analysis Software Tool (S.A.S.T) is aasigned for measuring soil parameters with the possibility of integration into the system of research and online recommendations for optimization of consumables. Presented results makes a significant contribution to the concept of precision agriculture technic as farming IT model based on observing, control, detection regarding to inter and/or intra-field productive variability.
