Пять лет Лигой преподавателей высшей школы реализуется проект, направленный на обучение преподавателей высших учебных заведений России. Преподавателями и разработчиками образовательных модулей и программ являются победители Всероссийского конкурса «Золотые имена высшей школы» (в этом году конкурс проходит в седьмой раз). Разработано и реализуется 7 программ курсов повышения квалификации и одна программа профессиональной переподготовки. К созданию образовательного контента были привлечены более 50 преподавателей из 14 ведущих вузов страны, что позволило наименовать это направление как «Межвузовский образовательной кластер». Обучение проходит как в дистанционном, так и в очном форматах. В апреле 2025 года в очном формате в г. Тула прошел инженерный образовательный трек. Участники трека представили собственные проекты и приняли активное участие в обсуждении проектов, представленных участниками образовательного трека. For five years, the University Teachers League has been implementing a project aimed at training faculty members of higher education institutions across Russia. The developers and instructors of educational modules and programs are winners of the All-Russian competition "Golden Names of Higher Education" (this year marking its seventh edition). To date, seven continuing education programs and one professional retraining program have been developed and implemented. More than 50 teachers from 14 leading universities in the country have been involved in creating the educational content, giving rise to what has been termed the "Inter-University Educational Cluster." The training is delivered in both distance and in-person formats. In April 2025, the Engineering Educational Track was held in person in the city of Tula. Participants presented their own projects and actively engaged in discussions of projects submitted by fellow track participants.

Description of the internal spatial structure and texture of geological objects is an important element in their study. A qualitative description of the internal morphology of samples, despite its clarity and wide applicability, does not have a sufficient degree of accuracy and detail. Quantitative description would provide the information in a compact form. This information can be used straightforwardly for classification and comparison with other samples and for evaluation of effective physical characteristics. Integral geometry and algebraic topology provide a set of powerful tools for the quantitative characterization of complex spatial structures regardless of their nature. An approach to quantitative characterization of the spatial structure and texture using the example of segmented rock sample has been developed in this paper. Segmentation in our paper means distinguishing X-ray density phases. The approach is based on integral geometry and algebraic topology. The example of a meimechite sample from the Kontozero complex demonstrates the applicability of this approach for the quantitative analysis of structures in geological sample. A classifier for objects of selected X-ray density phases of geological samples based on their integral-geometric characteristics has been developed, and the stability of its operation has been demonstrated. Detailed analysis of the algebraic-topological characteristics for the selected X-ray density phases and their combinations has been carried out. The obtained results have been meaningfully interpreted in geological-genetic terms. The developed approach will allow describing the volume distribution of more than two phases in any natural and synthesized substance or even space of properties. In this case, the phase can also be understood as the distribution of properties, which makes the approach widely applicable in many science sections.

Важнейшим фактором работоспособности сельскохозяйственной и строительной техники на удаленных сельскохозяйственных угодьях является обеспеченность ее запасными частями, инструментами и материалами для проведения ремонта и технического обслуживания. В условиях внешнего финансового и логистического давления и ограничения поставок необходимых для ремонта техники материалов и запасных частей стали возникла проблема содержания и обслуживания техники, решению которой посвящена данная работа. В работе предложены подходы для организации информационной системы материально-технического обеспечения региона и сформировать мобильные станции технического обслуживания для ремонта техники на удаленных объектах. The most important factor in the performance of agricultural and construction equipment on remote agricultural lands is the availability of spare parts, tools and materials for repair and maintenance. In the context of external financial and logistical pressure and limited supplies of materials and spare parts necessary for equipment repair, the problem of equipment maintenance and service has arisen, the solution of which is the subject of this work. The work proposes approaches to organizing an information system for the region's material and technical support and to form mobile service stations for equipment repair at remote sites.

Understanding processes of wave-turbulence interactions in stably stratified shear flows is a challenging problem in atmospheric physics and hydrography. This observational study emphasizes the importance of carefully considering Kelvin–Helmholtz (KH) waves and their interaction with vortical turbulence for an adequate description and parametrization of the stable boundary layer. This study investigates two phenomena, traditionally discussed separately, occurring during the morning transition from stable to unstable stratification at Dome C, Antarctica. Using high-resolution sodar echograms, the simultaneous occurrence of (i) the morning rise of the inversion turbulent layer, and (ii) KH waves within this layer was observed. Regular braid-like structures associated with KH shear instabilities within the elevated turbulent layer were observed in more than 70% of days over a four-month summer period. Two regimes of the morning evolution (when KH waves occurred) are identified, depending on the presence or absence of turbulence during the preceding night. The weather and turbulent conditions favoring the occurrence of these regimes are analyzed corresponding the morphology of the wind and temperature fields retrieved from an instrumented 45-m tower with six measurement levels. Two distinct patterns of KH waves are observed: (1) quasi-periodical (with periods ≈ 8−15 min) trains containing 5−10 braids, (2) about continuous series lasting 20–70 min containing 20−80 braids. A composite shape of KH waves is determined. The periodicity of these waves is estimated to be between 20 and 70 s, and their wavelength is estimated roughly to be 100−400 m. The vertical thickness of individual braids at the wave crests ranges between 5 and 25 m. The total depth of a rising turbulent layer containing these waves varies between 15 and 120 m, and the ratio of the wavelength to the depth of the wave layer varies from 3 to 12 with a mean value ≈ 8. Numerical simulations face challenges in reproducing turbulent wavelike structures, particularly KHBs. Further investigation is needed to unveil the precise mechanisms driving the morning elevation and growth of KH waves along with the developing convective layer.

The purpose of this study is to analyze the innovative development of transport and logistics activities of fishing companies, which is especially important in connection with the introduction of sanctions. The article focuses on the extraction and transportation of live crab over long distances due to the reorientation of cargo flows. The introduction of advanced technologies for the transportation of live crab by LLC "Antey-Sever" is being considered.

During night flights of unmanned aerial vehicles, determining the location of the device during take-off and landing and the possibility of injury to maintenance personnel from a rotating propeller poses a certain problem. The problem is especially pronounced with a large diameter of rotor blade, which is difficult to highlight with a strobe light. The article describes the design of the rotor blade tip’s illumination system, which can be placed on propellers of any diameter without an additional battery source. This allows not only to make these lighting systems maintenance-free but also to fly in extreme conditions of low temperatures. This novelty will be especially useful when operating in the Arctic, where the polar night lasts for several months and there are very low ambient temperatures.
