Program Implementation of Educational Electronic Resource for Inclusive Education of People with Visual Impairment
(2023) Tulashvili, Yurii; Lukianchuk, Iurii; Lishchyna, Valerii; Lishchyna, Nataliia
It is substantiated that the educational software used in the educational process during the computer training of visually impaired people contributes to the formation of their correctional and compensatory devices for the use of computer technology. The peculiarities of the inclusive educational process of professional training of persons with visual impairments with the use of computer technology are pointed out. The architecture and features of creating educational software for the visually impaired are revealed. A mathematical model and algorithm for its implementation of educational software for support of inclusive educational process of professional training of persons with visual impairments have been developed. The developed training software presents the theoretical content of training in an adapted form. The developed practical tasks contain an exhaustive list for the formation of correctional and compensatory devices and the acquisition of skills and abilities to use computer technology for people with visual impairments.
Model of formalized information security audit of an organization with a critical infrastructure facility for compliance with international security standards
(CEUR-WS, 2025) Lishchyna, Nataliia; Lishchyna, Valerii; Kozubtsov, Igor; Yashchuk, Andrii
The article emphasizes the importance of conducting information security audits for information systems of critical infrastructure organizations. Effective protection is ensured by aligning security systems with international standards. The audit monitors and assesses compliance but remains effective only when performed regularly by trained specialists. Due to the routine nature of audits and wartime constraints, such as power outages and loss of communication, AI-based methods are often impractical. Therefore, the authors propose a temporary solution using formalized security assessment criteria with clear indicators for objective verification. The study develops a methodology for conducting audits aligned with international standards, addressing the lack of practical guidance in existing ones. It also analyzes global regulatory documents to identify typical management approaches and proposes an adaptable checklist-based methodology covering 10 key information security areas, particularly useful for organizations operating under wartime conditions. © 2025 Copyright for this paper by its authors.
Mobile Robot Motion Stability and Optimal Chassi Construction
(2021-09-15) Lishchyna, Nataliia; Lishchyna, Valerii; Gumenyuk, Pavlo
The paper presents the results of dynamical modeling, simulation and stability analysis of mobile robot, which makes it possible to explain some dynamic effects that lead to instability of the straight-line robot's movement and skidding at bends at high speeds. This model is used to analyze the stable motion of wheeled robot in accordance to mutual placement of the wheels and the center of mass during its movement along the straight line. The appropriate recommendations are given on the optimal chassis design to avoid the phenomenon of instability motion.
DIY Smart Auxiliary Power Supply for Emergency Use
(Springer Nature Switzerland, 2023) Zdolbitska, Nina; Delyavskyy, Mykhaylo; Lishchyna, Nataliia; Lishchyna, Valerii; Lavrenchuk, Svitlana; Sulim, Viktoriia
Implementation of Internet of Things technologies in various fields is one of the priority areas of modern development. Energy efficiency is one of the urgent problems in Ukraine today. As part of this study, the use of IoT will help monitor and control energy consumption data. Auxiliary power supplies are devices that provide supplemental power to an existing power source. They are often used in automotive, electrical, and industrial applications. DIY auxiliary power supplies are those that are built by the user instead of purchasing a ready-made product. Building your own power supply can be a cost-effective option, as well as an enjoyable DIY project. The purpose of the research is to develop a device based on the existing electrical engineering components, which allows you to completely or partially replace the functionality of industrial analogs of power supplies.
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, Valerii
The 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.
