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.
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.
It is essential to measure the components of Earth's magnetism, including its configuration, spatial distribution, short-term and long-term variations, and its relationship with other phenomena originating on the Sun, in the atmosphere, or within the Earth. Modern instruments enable high-precision measurements of the components of the geomagnetic field. However, in certain situations-such as emergencies in marine navigation-a conventional compass may remain indispensable. The authors propose a device whose design rivals the simplicity of the classical compass. This instrument eliminates the structural drawbacks of dry friction between the elements of a conventional compass by using a fluid support, which removes dry friction within the device, thereby significantly increasing its sensitivity and enabling the measurement of magnetic declination and its variations. The results of experimental investigations of the device are presented. It can measure the geomagnetic field's declination and its temporal changes. Its simple construction and high sensitivity compared to a standard compass make it a promising tool for numerous practical applications. The device is capable of detecting even minute variations (on the order of arc minutes) in magnetic declination caused by short-term disturbances over the course of a day (diurnal variation). The instrument can function as a portable autonomous device for research in meteorology, geophysics, and navigation.
The work investigated the effect of organic biogenic microdispersed lignocellulosic filler on the physical, mechanical and thermophysical properties of epoxy composites. Attention is paid to the analysis of structural and interfacial effects that occur at the micro- and nanolevels and determine the performance characteristics of materials. The elemental composition of the filler was investigated using X-ray fluorescence analysis, which enabled the identification of mineral components capable of forming active centers that facilitate interfacial interaction with the epoxy matrix. The organic component of the filler was investigated by gas chromatography with mass spectrometric detection. At the same time, the presence of fatty acids and their glycerol esters with polar functional groups capable of participating in intermolecular interactions was revealed. It has been proven that the introduction of a filler with a content of q = 1,0…1,5 wt.% provides an increase in the destructive stresses during bending, the modulus of elasticity, the impact strength of epoxy composites, and a complex of thermophysical properties. This is due to the action of various mechanisms, in particular physical reinforcement and stress relaxation in the polymer volume. The results of comprehensive studies confirm that the biogenic lignocellulosic filler performs not only the role of a dispersed reinforcing component, but also the function of a structure-forming element that provides directed control of the properties of epoxy composites due to nanolevel interfacial interaction. This opens up prospects for creating functional polymer materials with predicted physical, mechanical and thermophysical characteristics.
