    Information System for Air Quality Assessment and Data Processing: Design and Implementation
    (CEUR-WS Team, Aachen, Germany, 2024) Hnatushenko, Volodymyr V.; Bulana, Tetiana; Gomilko, Igor; Molodets, Bohdan; Boldyriev, Daniil
    ENG: In recent years, the issue of air quality has become increasingly critical. This article presents a hardware and software-based solution for collecting and processing data from ground stations monitoring air quality. The system is designed to collect real-time data from monitoring stations, store the data in a central database, perform data processing, and detect anomalies. Additionally, the system offers data visualization through maps and tables. The developed solution consists of three core components: a web server, a web application, and ground stations. A key feature of the software is its ability to handle real-time data aggregation and fill data gaps using custom-built aggregators. This is achieved through real-time data parsing, managed by Celery workers and queued via RabbitMQ. All data is stored in an SQL database, with PostgreSQL and Django frameworks facilitating database management and administration. Python scripts are used to process raw data into user-friendly formats such as AQI indices and graphical representations. The system is designed for seamless deployment across multiple remote servers, ensuring high flexibility and reliability for researchers. This software architecture enables scalable, conflict-free deployment, enhancing the efficiency and accuracy of air quality assessments.

    Substantiation for the Selection of Parameters for Ensuring Electrothermal Protection of Solar Batteries in Spacecraft Power Systems
    (РС Тесhnology Сеntеr, Kharkiv, Ukraine, 2022) Hilorme, Tetiana; Nakashydze, Liliya V.; Mazurik, Stanislav; Gabrіnets, Volodymyr O.; Kolbunov, Vadim; Gomilko, Igor
    ENG: A relevant scientific-practical issue related to the sustainable development of outer space is the selection of optimal parameters of solar panels for the uninterrupted supply of energy in the power plants of spacecraft. It has been determined that advancing energy-efficient technologies is a prerequisite for ensuring stable space activities. The decision-making process regarding the choice of alternative options for ensuring the electrothermal protection of solar panels in the power plants of spacecraft occurs under the conditions of uncertainty and various risks. A methodical approach to assessing the effectiveness of options for building electrothermal protection systems for solar panels in the power plants of spacecraft has been devised. The hierarchical structure of the problem about approving of the choice of electrothermal protection of solar panels has been constructed on the basis of the method of analytical hierarchical process, which makes it possible to derive a set of optimal options. Five alternative options for electrothermal protection of solar panels have been chosen, which, unlike existing ones, take into consideration the phases of the life cycle, namely, the period of active operation. The selection of criteria for choosing the parameters of ectrothermal protection of solar panels in the power installations of spacecraft has been substantiated: ensuring the smooth operation of solar panels; availability of service in emergencies; the life cycle of solar panels; the cost of solar panels; technical safety; mass-size indicators. It is argued that the chosen optimal alternative “Solar panels with protection on the basis of self-resetting fuses” could prolong the active life cycle and, as a result, reduce the number of repairs (current and overhaul) of solar panels in space activities. Owing to the use of this option, positive results could be achieved such an increase in the active life cycle by 20 %, as well as an increase in technical safety by 24 %.
