Лістратенко – Запоріжжя: НУ «Запорізька політехніка», 2023. – 62 с.UK: У дипломному проекті проведено порівняльний аналіз трьох алгоритмів адаптивної фільтрації методом найменших квадратів (МНК, НМНК і РМНК) для адаптивного шумопригнічувача. Алгоритми адаптації фільтра, засновані на методі найменших квадратів, здатні очистити гармонійний сигнал від шумів, але не здатні боротися з нестаціонарною завадою. Алгоритм РНК має більш швидку збіжність, порівняно до МНК, що досягається за рахунок більш високої (порівняно до алгоритму МНК) обчислювальної складності.
EN: In the diploma project, a comparative analysis of three adaptive least-squares filtering algorithms (MNK, NMNK, and RMNK) for an adaptive noise suppressor was carried out. Filter adaptation algorithms based on the method of least squares are able to clean the harmonic signal from noise, but are not able to deal with non-stationary interference. The RNA algorithm has a faster convergence compared to the MNK, which is achieved due to higher (compared to the MNK algorithm) computational complexity
Ecologization of tourist activities as a factor of sustainable development of the regions of Ukraine
No full textThe article is devoted to the problem of sustainable development of Ukraine's regions, since competitive regions are a source of balanced and sustainable development of the entire country. It was emphasized that the development of the development management strategy of any region of Ukraine should be based on the environmental safety policy, the current norms and requirements of which must be adapted in accordance with European standards. The subject of the study is the greening of tourist activity as a factor in the sustainable development of the regions of Ukraine. The purpose of the study is to build a model of sustainable development of regional tourism based on the ecosystem restoration of security of the tourist and recreational potential of Ukraine in the post-war period. Tasks that were set to achieve the goal: to investigate the management mechanism of sustainable development of regional tourism; to analyze the impact of military actions on the ecological state of the regions of Ukraine; to propose a program model for the sustainable development of tourism in Ukraine. In accordance with this direction of research, the author chose and applied the following methodological approaches: systemic and institutional when considering the interrelationships of actors at both the national and regional levels. Within the framework of the system approach, the functioning of the tourism industry of Ukraine was investigated within the framework of new ecological realities. Thanks to the institutional approach, the necessary legal framework for the sustainable development of tourism was considered. The following results were obtained. The authors proposed the formation of a model of sustainable development of tourism, which emphasizes the sustainability of ecological, economic, cultural and social spheres, taking into account the ranking of factors of sustainable development depending on the level of sustainability. The proposed model takes into account an important aspect - after the war, it will be necessary to ensure different levels of sustainability for individual regions of Ukraine
