Item type:Наукова стаття, Latency Reduction in Real-time GPS tracking in Android and the Web-based GPS Monitoring System(IEEE, 2022-12-09) Tsindeliani, Davyd; Povstiana, Yuliia; Lishchyna, Nataliia; Yashchuk, AndriiThe paper focuses on the research aimed to reduce latency in real-time GPS-tracking and implementation of a real-time web GPS-monitoring system based on Android devices that publicly provides access to users' locations. A real-time GPS monitoring system with low latency consists of three main components: a web front-end client, a server part, and an Android application. During the development process, the performance of WebSocket back-end frameworks was researched. The performance of Google Maps and Leaflet (OpenStreetMap) was compared to select the option which provides the best performance in the developed system. The conducted research and the chosen solutions for the implementation of the project made it possible to develop a system that shows high efficiency and performance. The developed software allows any user with an Android mobile device to share their location with others with minimal latency and show their location and traffic history. © 2022 IEEE.Item type:Наукова стаття, A Web-Based Approach for Assessing CO2 Emissions during the Russo-Ukrainian War(Greece, 2024-10-11) Surynovych, Olena; Lishchyna, Nataliia; Yashchuk, Andrii; Povstiana, Yuliia; Lishchyna, ValeriiThe paper is devoted to the development of a web service for calculating and reducing CO2 emissions into the atmosphere during the Russo-Ukrainian War. An analysis and study of the environment of the regions of Ukraine in 2023 was carried out. Emissions from the hostilities in Ukraine are described in detail. An analysis of existing methods and technologies for calculating CO2 emissions was carried out. A prototype of the web service interface was developed to visualize the main elements and functionality of the system. The software was thoroughly tested with various fuel types to ensure compliance with standards and requirements. The architecture and functionality of the web service are partially described.
