In our work we consider the issues of complex automated systems designing at the stage of engineering design. There is formulated the issue of system decomposition into applied tasks clusters subject to automation and of initial documents used for automated systems functional tasks solving. The problem is solved as a block-symmetric task of discrete programming. Solving the formulated tasks is proved to be effective with interactive algorithm which allows solving the high dimension tasks. The developed decomposition method allows optimizing the automated systems designing.

The aim of the study is to increase the effectiveness of automated face recognition to authenticate identity, considering features of change of the face parameters over time. The improvement of the recognition accuracy, as well as consideration of the features of temporal changes in a human face can be based on the methodology of artificial neural networks. Hybrid neural networks, combining the advantages of classical neural networks and fuzzy logic systems, allow using the network learnability along with the explanation of the findings. The structural scheme of intelligent system for identification based on artificial neural networks is proposed in this work. It realizes the principles of digital information processing and identity recognition taking into account the forecast of key characteristics’ changes over time (e.g., due to aging). The structural scheme has a three-tier architecture and implements preliminary processing, recognition and identification of images obtained as a result of monitoring. On the basis of expert knowledge, the fuzzy base of products is designed. It allows assessing possible changes in key characteristics, used to authenticate identity based on the image. To take this possibility into consideration, a neuro-fuzzy network of ANFIS type was used, which implements the algorithm of Tagaki-Sugeno. The conducted experiments showed high efficiency of the developed neural network and a low value of learning errors, which allows recommending this approach for practical implementation. Application of the developed system of fuzzy production rules that allow predicting changes in individuals over time, will improve the recognition accuracy, reduce the number of authentication failures and improve the efficiency of information processing and decision-making in applications, such as authentication of bank customers, users of mobile applications, or in video monitoring systems of sensitive sites.

The purpose of this research is to segment the chest on X-rays, a crucial step in medical image processing pivotal for diagnosing and treating lung diseases. By employing modifications to the U-Net model, this study endeavors to enhance chest segmentation on X-rays. The approach includes introducing alterations to the basic architecture of the U-Net model, integrating Inception blocks, and a using a squeeze-and-excitation mechanism to improve segmentation accuracy. The Shenzhen dataset, comprising chest radiographs, serves as the subject of investigation, highlighting the practical application of these modifications. The utilization of the MIU-Net model for automatic chest organ segmentation underscores its significance in the realm of lung disease diagnosis and treatment. Experimental methodologies encompass two types of data augmentation: Contrast Limited Adaptive Histogram Equalization (CLAHE) and the introduction of Gaussian noise, to test the model's robustness under various conditions. A comparative analysis is conducted against both the baseline U-Net and U-Net with Inception blocks. The results show that the improved U-Net model that includes Inception and Squeeze-and-Excitation (SE) is a lot better than the original U-Net. Specifically, the Dice coefficient for the improved model stands at 0.9040 for the original data, 0.9306 with CLAHE application, and 0.9232 with Gaussian noise addition. These findings underscore the importance of the research, emphasizing the significance of improving the accuracy of chest segmentation on X-rays for early disease detection and treatment optimization, which are the practical implications of this study. The research’s implications extend beyond academic interest, offering potential enhancements in clinical practices for lung disease management.

В статье представлена концептуальная модель веб-ориентированной системы мониторинга мостовых конструкций. Актуальность исследования обусловлена необходимостью своевременного выявления дефектов для предотвращения аварий. Цель работы – создание модели системы мониторинга с использованием волоконно-оптических датчиков с наклонной решеткой Брэгга. Разработана функциональная структура с шестью подсистемами и модель базы данных с восемью сущностями. Созданы UML-диаграммы, описывающие взаимодействие пользователей с системой. В качестве технологического стека выбраны Python/Django, Vue.js и PostgreSQL. Практическая значимость работы заключается в возможности использования модели для создания систем мониторинга мостовых сооружений.
