Modern society needs specialists who are ready to work in a high-tech professional environment. The use of augmented reality and virtual reality technologies is a key area of professional development in the near future, including within educational institutions, to optimise the process of forming students' professional competence in the context of learning English. The purpose of the article is to study and analyse the existing experience of using educational technologies of augmented and virtual reality in teaching a foreign language. Methodology and methods: the lack of a sufficient research base dedicated directly to the experience of implementing AR and VR technologies in teaching foreign languages to university students led to the choice of a comprehensive research methodology: theoretical analysis of scientific and pedagogical literature on the topic of the study, description and analysis of the research results. As a result, the article analyses the use of augmented and virtual reality technologies in teaching foreign languages, their purpose and functions. The advantages and disadvantages of augmented and virtual reality technologies are reflected. Conclusions: the study demonstrated that educational technologies are potentially effective in teaching foreign languages at universities, and many of their shortcomings can be eliminated in the coming years in the context of neuropedagogical technologies.
Abradable coatings are used in modern gas turbine engines to minimise clearances and reduce gas leakage through the blade tips. The development of wear-resistant coatings for turbine casings is challenging due to the high-temperature operating conditions and aggressive fuel combustion products. The balance between erosion and abrasion resistance of coatings necessitates the search for new optimal solutions. This article discusses the properties of two new abradable coatings based on composite powders. The composite powders were synthesised by mechanochemical alloying of aluminium, silicon (8%) and boron nitride (20%). The main component were industrial aluminium powders of two types, obtained by spraying primary aluminium melt, with a rounded and elongated shape, which affected the porosity of the sprayed coatings, which was 2.8% and 9.5%, respectively. The prepared powder was coated by Atmospheric Plasma Spraying (APS) with generating a laminar plasma jet. As a result, abradable coatings with the required set of performance properties were obtained. Emphasis is placed to the structure, chemical composition, and microhardness of coatings made of round and elongated powders. The resulting coatings can be recommended for use as abradable coatings. Among the considered coatings, elongated powder coatings have higher hardness and potentially higher abrasive and erosion resistance for high-temperature turbines.
This article addresses the critical challenge of optimizing ship machinery maintenance systems by integrating digital strategies. It examines adaptive maintenance approaches that consider real-time equipment condition, predictive analytics, and cost efficiency. A comparative analysis of existing methodologies is presented, highlighting their advantages and limitations. The study introduces an enhanced framework that incorporates machine learning models, sensor-based monitoring, and an improved decision-making process for maintenance scheduling. Experimental results demonstrate the effectiveness of adaptive strategies in minimizing downtime, reducing operational costs, and extending the lifespan of ship machinery. Practical applications and long-term implications for maritime industry stakeholders are also discussed. Additionally, the article explores the economic and operational impacts of changes in technical conditions, emphasizing cost-effectiveness and time optimization in servicing practices. The findings advocate for adaptive maintenance approaches that ensure efficient ship operation, reduce downtime, and enhance the overall productivity of maritime transport.
The article puts forward and investigates the hypothesis that the formation of Ocean Literacy in future marine engineers ensures their compliance with the regulatory IMO requirements and contributes to the sustainable development of the maritime industry. Based on the analysis of modern scientific approaches to the interpretation of the Ocean Literacy concept, clarification of the connection between the Ocean Literacy concept, requirements of IMO regulatory documents for the professional training of marine engineers and goals of sustainable development, the content of the concept "ocean literacy" is interpreted, as an integrated competence that combines professional knowledge (hard skills), universal skills (soft skills), moral and ethical values, environmentally responsible behavior and readiness to make professional decisions in accordance with sustainable development. As a result of establishing the relationship between the principles of Ocean Literacy and the requirements of IMO documents, the place of Ocean Literacy of marine engineers in the structure of their professional competence was clarified and conceptual model of integrating Ocean Literacy into the structure of marine engineers professional training was developed. Promising directions for integrating Ocean Literacy of marine engineers into the structure of professional training during Marine English learning were outlined: consideration of environmental issues in the context of the marine engineers' professional activity; training in solving environmental problems when analyzing English-language maritime cases; development of environmentally responsible decisions in simulation exercises; involvement of interdisciplinary knowledge for a deep understanding of the problems and needs of the ocean; application of assessment components of learning outcomes that test the level of environmental competence
