Item Аналіз можливості застосування технології blockchain у сфері управління ланцюгами постачань(ЦНТУ, 2023) Шльончак, І. А.; Солтус, А. П.; Рудь, М. П.; Shlionchak, I.; Soltus, А.; Rud, M.В статті виконано детальний аналіз вітчизняного та закордонного досвіду використання технології blockchain. Показано позитивний досвід такого використання. Акцентовано увагу на перевагах і недоліках даної технології. Проведено моніторинг доходів відомих світових компаній, що застосовують зазначену технологію. Підкреслено можливість ефективного використання blockchain-технології в сфері управління ланцюгами постачань в українській перспективі, особливо беручи до уваги європейський вектор розвитку країни. Human life in today's world is increasingly becoming faster and more popular in the digital format. Such a trend is observed in almost any sphere of human activity. And supply chain management is no exception. It is in the field of supply chain management that a digital approach to solving various problems is an extremely urgent task facing scientists today. The article provides a detailed analysis of the domestic and foreign experience of using blockchain technology. Positive experience of such use is shown. Attention is focused on the advantages and disadvantages of this technology. Monitoring of revenues of well-known global companies using the specified technology was carried out. The possibility of effective use of blockchain technology in the field of supply chain management in the Ukrainian perspective is emphasized, especially taking into account the European vector of the country's development. One of the European countries, namely Estonia, can be cited as an example of the effective use of blockchain technologies. One of the reasons for this is state support for digital technologies. The Estonian project is the most successful of the world's digital projects. Summing up, it should be noted that the application of blockchain technology has great prospects for effective use in the digital sphere of any human activity, in particular, in the management of supply chains. In the work, the main advantages and disadvantages of the mentioned technology were highlighted in order to establish greater efficiency of its application in the field of supply chain management. Based on the above, it should be concluded that blockchain digital technology is a promising system in the Ukrainian vector of European integration.Item Розробка алгоритма моніторингу стану водія за допомогою Аndroid-застосунку з метою підвищення рівня активної безпеки(ЦНТУ, 2023) Йовченко, А. В.; Шльончак, І. А.; Yovchenko, А.; Shlionchak, I.В статті виконано аналіз методів моніторингу небезпечного стану водія під час руху транспортного засобу. Наведено перелік програм, які використовуються при цьому. Для проведення досліджень було обрано мобільний додаток Drive Safely, в основу роботи якого покладено моніторинг стану очей та роту водія. Згідно проведених досліджень PERCLOS очей не повинен перевищувати 28 %, а PERCLOS роту не повинен перевищувати 30 %. Розроблено алгоритм розпізнавання аварійних ситуацій у кабіні транспортного засобу на основі зображення очей та роту водія із фронтальної камери смартфону. The purpose of the research is the analysis of existing systems for monitoring the driver's condition using an Android mobile application to increase the level of active safety with the development of an algorithm for monitoring the driver's condition. At the same time, such parameters as turns and tilts of the head, duration of eyelid blinking, yawning are taken into account. As a result, the state of drowsiness, impaired attention, and drunkenness of the driver is analyzed. The article analyzes the methods of monitoring the dangerous condition of the driver during the movement of the vehicle. The list of programs used in this case is given. The Drive Safely mobile application was chosen for the research, which is based on monitoring the condition of the driver's eyes and mouth. Based on research, eye PERCLOS should not exceed 28% and mouth PERCLOS should not exceed 30%. An algorithm for recognizing emergency situations in the vehicle cabin based on the image of the driver's eyes and mouth from the front camera of a smartphone has been developed. As a result of the analysis of existing Android applications, an algorithm for recognizing emergency situations in the cabin of the vehicle was developed. The algorithm was obtained based on the image of the smartphone's front camera. This algorithm takes into account all possible dangerous conditions of the driver behind the wheel of the vehicle. As a result of the conducted research, an analysis of the existing systems for monitoring the driver's condition using the Drive Safely mobile Android application was carried out. As a result of the analysis of existing Android applications, an algorithm for recognizing emergency situations in the cabin of the vehicle was developed. The use of this algorithm in the program and the connection of its results to the cloud environment will allow it to self-improve and increase the efficiency of its operation, thus increasing the level of active security.Item Розробка алгоритма моніторингу стану водія за допомогою Аndroid-застосунку з метою підвищення рівня активної безпеки(ЦНТУ, 2023) Йовченко, А.
