Application of combinatorial design principles
Author:

Bibliographic description of the article for the citation:

. Application of combinatorial design principles//Science online: International Scientific e-zine - 2025. - №7. - https://nauka-online.com/en/publications/technical-sciences/2025/7/02-42/

Annotation: The field of all types of innovation is typically saturated with a wide range of conventionally applied technical solutions and materials. Therefore, the implementation of innovative changes must be adapted to and integrated with traditional technologies and materials. In general, innovation is not a goal in itself. The central objective of the entire innovation process is to achieve a final result that leads to a qualitative improvement of all parameters of the therapeutic process, while ensuring the continuity of technologies, engineering solutions, and materials — including consumables. Developers have presented their first quantum computer and joined the global race for “quantum supremacy.” The first 20-qubit computer employs modern superconducting technology.

Bibliographic description of the article for the citation:

. Theoretical principles of automated analysis of DDD compliance//Science online: International Scientific e-zine - 2025. - №6. - https://nauka-online.com/en/publications/technical-sciences/2025/6/01-44/

Annotation: This article explores the problems and challenges of automating the analysis of compliance of software systems with Domain-Driven Design (DDD) principles. The main obstacles are identified, including the lack of standardized formal models of the domain area, the difficulty of identifying domain concepts in code without explicit annotations, the diversity of DDD practices across real-world projects, and the technical limitations of current analysis tools. The paper provides a classification of existing architectural analysis approaches, including static and dynamic code analysis, the use of metadata and annotations, domain knowledge modeling through UML and DSLs, and the application of machine learning methods. Promising research directions are outlined, focusing on the development of formal models and metamodels, the integration of compliance verification into CI/CD processes, and the creation of hybrid analysis methodologies. The study aims to contribute to the foundation for future development of tools ensuring the architectural quality of complex software systems.

Fiber-optic sensors for monitoring gas leaks and temperature in industrial facilities
Author:

Bibliographic description of the article for the citation:

. Fiber-optic sensors for monitoring gas leaks and temperature in industrial facilities//Science online: International Scientific e-zine - 2024. - №6. - https://nauka-online.com/en/publications/technical-sciences/2024/6/05-25/

Annotation: The article discusses the theoretical foundations and practical application of fiber-optic sensors (FOS) for detecting gas leaks and monitoring temperatures at industrial facilities. A comprehensive analysis of the operating principles of FOS, their classification, signal modulation methods, and distributed sensing is carried out. Particular attention is paid to their application in aggressive environments, including in the oil and gas, chemical, and energy industries. The advantages and limitations of the technology are presented, as well as the prospects for its development within the framework of industrial digitalization and the implementation of IoT solutions. Directions for further research, including intelligent signal analysis, increased selectivity, and standardization of application are considered separately.

Real-time active online monitoring systems in leather manufacturing processes

Bibliographic description of the article for the citation:

. Real-time active online monitoring systems in leather manufacturing processes//Science online: International Scientific e-zine - 2025. - №5. - https://nauka-online.com/en/publications/technical-sciences/2025/5/06-24/

Annotation: A real-time active online monitoring system for leather manufacturing processes is presented, fully tailored to the specific requirements of the leather industry. The system employs contactless resonance sensors as a key component, integrated across all stages of hide processing—from soaking (used to remove preservatives, dirt, and blood), liming, hair removal, and deliming to tanning (including vegetable tanning), dyeing, fatliquoring, drying, and finishing. The importance of continuous parameter monitoring in the "dead zones" of technological tanks is highlighted, along with the design of the sensor module (a sleeve with a solenoid coil) and its manufacturing methods, including the application of RITM technologies. The paper outlines approaches to integrating the sensors into the production line and discusses the anticipated benefits: improved uniformity of hide processing and final leather quality, reduced defect rates through timely detection of deviations, and automatic real-time adjustment of processing modes according to raw material properties.
