Ultrahigh-energy cosmic-ray signature in GRB 221009A
Authors: Das Saikat , Razzaque Soebur
Published: January 2023

The brightest long gamma-ray burst (GRB) detected so far by the Swift-BAT and Fermi-GBM telescopes, GRB 221009A, provides an unprecedented opportunity for understanding the high-energy processes in extreme transient phenomena. We find that the conventional leptonic models for the afterglow emission from this source, synchrotron and synchrotron-self-Compton, have difficulties explaining the observation of ≳10 TeV γ rays (as high as 18 TeV) by the LHAASO detector. We modeled the γ-ray spectrum estimated in the energy range 0.1–1 GeV by the Fermi-LAT detector. The flux predicted by our leptonic models is severely attenuated at > 1 TeV due to γγ pair production with extragalactic background light, and hence an additional component is required at ≳10 TeV. Ultrahigh-energy cosmic rays can be accelerated in the GRB blast wave, and their propagation induces an electromagnetic cascade in the extragalactic medium. The line-of-sight component of this flux can explain the emission at ≳10 TeV detected by LHAASO, which requires a fraction of the GRB blast wave energy to be in ultrahigh-energy cosmic rays. This could be an indication of ultrahigh-energy cosmic-ray acceleration in GRBs.
Impact of Floods in the Kolyma River Delta on Navigation Conditions in the East Siberian Sea
Authors: Kholoptsev Alexander , Podporin Sergei , OlKhovik Evgeniy
Published: January 2023

Problem of improving the quality of medium- and long-term forecasting of changes in ice conditions in the Northern Sea Route, and in particular in the east Siberian sea, where one of the methods of selecting waterways is the passage of ships in areas of ice-covered polynya. The hypothesis is verified that during the summer months, such changes may be significantly influenced by the timing of the onset of high water in the Kolyma River delta. Data from the global reanalysis GLORYS12v1 supported by the European Copernicus Marine Service were used as factual material on the ice cover and levels of the East Siberian Sea in the months of May to October 1993-2019. The analysis is based on mathematical models of the NEMO family verified by satellite altimetry data. Using the developed methodology, the dates of abrupt changes in level and sea ice extent on the Kolyma River estuarine seashore have been estimated for selected periods of the year. The study uses statistical methods to confirm the validity of the stated hypothesis for a number of areas of the East Siberian Sea, through which the shipping routes of the Northern Sea Route pass. It has been established that the greatest influence of flood timing on ice conditions and navigation conditions in such areas takes place in July. It is shown that early floods in the Kolyma delta generally lead to improvement of ice conditions, while late floods lead to complication of ice conditions. The identified relationships are recommended for use in forecasting changes in ice conditions. It has been suggested that with further climate warming and shifting of flood dates to earlier dates, the complication of ice conditions due to freezing of the formed polynya is not excluded.

Authors: Smirnov Anton , Smolokurov Evgeniy , Smolina Olga , Gareeva Lia
Published: January 2023

The Saint Petersburg Metro was opened on 15 November 1955. It is the second largest subway in Russia after the Moscow Metro. The St. Petersburg Metro has stagnated since the early 2000s. This causes many problems for the transport network, such as high congestion of surface transport, especially in new areas of the city where there is no underground line. Also, the misallocation of underground traffic, the small number of regular and interchange stations per multi-million city. And what stops the development of the St. Petersburg metro is insufficient state funding, inefficient budget spending and poor construction quality. Development plans are shifted in terms of timing and in the end remain only on paper. The solution to these problems will allow Saint Petersburg to distribute the load on the surface and underground transport network, improving the quality of life of residents of St. Petersburg. Also, metro is a cultural heritage, and exclusive technologies were used to build it back in the USSR, and the central stations have their own design code.

Authors: Belousov Igor , Samoseiko Veniamin , Saushev Alecsandr
Published: January 2023

The process of pulse-width modulation in the converter-motor system is considered. It is noted that the main task of pulse width modulation of voltage formed by the electronic key converter in the converter-motor system is to reduce current pulsations during the modulation period. It is established, that the dynamic process of current change in the electric machine during the period of pulse-width modulation can be approximated by R, L filter. It is shown, that the most important task of pulse-width modulation is minimization of modulation error by current in electric motor. The analysis of possible criteria of estimation of modulation process quality in control systems of electric drive is carried out. It is noted that as a criterion of optimality to assess the quality of modulation in the converter-electromotor system, it is advisable to use the integral quadratic criterion of relative error, called the local variance of the current, as well as the average value of the local variance of the current at the period of the modulating function, called the integral variance of current. The process of estimating the filtering ability of electric machines as part of the electric drive is considered. A system of basic values based on nominal values of electric motor stator voltage, its nominal angular speed and nominal stator current has been selected. The index of filtering properties of the load considering introduction of basic values has been proposed. The equations of an asynchronous electric machine with constant coefficients in the complex form of writing are given. The dependency of the real part of roots of the characteristic equation for an asynchronous machine as a function of angular speed of the rotor rotation is constructed. An analytical expression for the estimation of the filtering properties of asynchronous machines is obtained. The comparison of different types of electric machines according to this parameter is made.

Authors: Smolentsev Sergey , Sazonov Anatoly , Ivanov Vladimir
Published: January 2023

The article deals with the problem of preventing ship collisions while at sea. When crewless ships meet at sea, it is necessary to ensure their safe separation. A formalization of setting the problem of safe divergence of a group of ships is given. Vessel subsets in various states in a group of ships are determined, and ship transitions from one state to another are described. The problem of a lack of mutual understanding between agents controlling unaccompanied ships is considered. A counter vessel may not perform the divergence manoeuvres that the agent controlling the uncrewed vessel expects. An analysis is made of the reasons contributing to this. The problem of detection of inadequate behaviour of a counter vessel or its violation of manoeuvring arrangements is offered. The criteria for detecting such behaviour and agent's actions to prevent collision in this case are considered.
Increasing the efficiency of automation in shipbuilding and ship-repairing by building a control system using lean manufacturing principles
Authors: Sokolov Sergey , Antonova Alena , Knysh Tatiana
Published: January 2023

Shipbuilding companies often suffer from long production cycles, low staff utilisation and an unbalanced production line. To solve these problems, a lean shipbuilding regime is used which involves work breakdowns, production plans and virtual flow operations that combine lean production with modern information management technology in shipbuilding. Production planning manages all the production activities of a shipbuilding facility. Production plans are achieved just-in-time through intelligent organisation, reducing loss of staff and time. A virtual flow operation is then carried out, achieving high efficiency in flow production and high flexibility in production. By implementing a lean shipbuilding regime based on task package planning and its production system, the ship's production cycle is reduced, the number of workers is reduced, but the level of production balance is increased.

Published: January 2023

It is difficult to overestimate the importance of the gas production business for the Russian economy, and therefore ensuring sustainable and innovative development of this sector of the economy is not just important, but a strategic vector of national economic security of the country: in case of a negative technological gap the impact of sanctions in terms of high-tech imports and overall dependence of the Russian economy on the "political mood" of global technological leaders in Western Europe and the United States is exacerbated. In addition, it should be noted the growing tightening of international environmental standards of oil and gas production, which determines the importance of digitalization of the oil and gas sector in Russia for its compliance with the green strategies of the world. The article is devoted to the study of practices of green investment and digitalization of the oil and gas sector in Russia, as well as the problems and prospects of its digital transformation, taking into account the best domestic and international practices of doing business in Industry 4.0. Separately, the article considers scenarios for the implementation of green investments in the oil and gas business in Russia using the "4 worlds" foresight method.

Published: January 2023

This paper is devoted to obtaining a solution to the problem of parametric vibrations and dynamic stability of thin-walled underground oil pipelines, taking into account the effect of a damper. An equation has been obtained that allows estimating the dynamic stability of underground oil pipelines, which consists in constructing regions on the plane of the parameters ωmn, ω0 and the longitudinal force parameter P, as well as the internal pressure p0, where ωmn is the frequency of free vibrations, ω0 is the excitation frequency. The assessment of the dynamic stability of the oil pipeline section is made for the known values of ωmn, ω0, p0, P, k by finding a point. If the point does not fall into the outlined area, it means that dynamic stability is ensured, otherwise there is a danger of parametric resonance.

Published: January 2023

The approach of logistics support of agro-industrial complexes with agricultural machinery and technical means for their maintenance in the planning of tender procurement procedures is considered. The proposed approach is based on the structure of the resource support of the agro-industrial complex, which is a complex organizational system. In the described structure of resources, a block of logistics support for vehicles and the material and technical resources necessary for its maintenance, the presence of which is important for solving functional and production problems, is singled out. On the basis of ongoing research, a cause-and-effect diagram has been developed with the definition of the most significant problems affecting the management of transport provision in agro-industrial complexes. A methodology for the expert assessment of the most demanded types of resources is proposed and described in order to optimize the spending of financial resources and increase the level of logistics support. The study of the approach under consideration is reduced to improving the procedure for planning tender purchases by developing and applying a model for determining and substantiating technical resources that are the most in demand for fulfilling the functional tasks of the agro-industrial complexes. As a result of the proposed model, the authors developed an algorithm for planning tenders, the practical application of which is based on achieving the objectives of the efficiency of spending financial resources and reducing the timing of tender procedures and their validity in terms of adequacy.

Published: January 2023

The paper analyzes the possible development of an approach limiting additional deformations of the base of a building during reconstruction. We consider the ultimate permissible value of additional relative hogging in a brickwork wall without reinforcement (f/L)ad,u, which is important for the solution of tasks on the reconstruction of historical buildings. The ultimate values of tensile deformations in a wall can serve as a safety criterion for uneven building settlements. The use of this criterion makes it possible to set more precise values (f/L)ad,u for a brick wall as compared with the values used in Construction Regulations SP 22.13330.

Published: January 2023

The digitization process has been going very fast lately as well BIM modelling, as both are strongly connected. The paper briefly evaluates this process from different levels, with the main focus on the conceptual level. The 3D geotechnical model of the ground comes to the fore, as this ground plays an important role also in the process of the BIM because practically all building structures are situated on this ground. Since the EN 1997 Geotechnical design also uses geotechnical and computational models, their connection with the BIM process is very useful and brings new possibilities. Especially from the point of view of connecting the design of the superstructure with substructure and ground and thus the presentation of the result in BIM model of the whole building. BIM models are presented not only for foundation structures, but also for earth structures and their advantages are shown, especially from the view of the decision-making process, as in the design and implementation phase so in throughout the service life of the building.
Reducing uneven deformations of the base through the use of strip self-adjusting foundations
Authors: Kukhar Anna , Lobacheva Nataliia
Published: January 2023

The article considers the reduction of uneven deformations of the base of the foundations of a five-story building, caused by local subsidence of the soil, through the use of strip self-adjusting foundations. The dependences of settlement, subsidence and stiffness coefficient of the self-adjusting foundation base on the load acting on it were obtained. Using the obtained dependences, numerical studies of the interaction of a building with a non-uniformly deformed subsidence base were performed. The results obtained showed the effectiveness of the use of self-adjusting foundations to reduce uneven deformations of the base and ensure the operational suitability of frameless buildings on subsiding soils. The uneven deformation of the base under the given conditions was reduced by about two times due to an increase in the penetration of the foundation into the ground. At the same time, the maximum shear stresses in the walls of the building decreased by about 30%.

Authors: Litvinov Vladimir , Gracheva Natalya , Rudenko Nelli
Published: January 2023

The article deals with issues related to increasing the efficiency of working with data on the geometry of the computational domain when solving hydrophysics problems using the finite difference method. The model problem is a system of equations of the pollutant distribution, including the oil and its refined products, in the computational domain – Azov Sea. To describe the computational domain, a model of a two-dimensional computational grid is used, which is used in the implementation of numerical calculations. Class diagrams are presented for describing the geometry of the object under study, as well as its constituent segments. In order to improve the performance of calculations, an algorithm for combining geometry segments was developed, in which the original algorithm was divided into separate fragments by introducing a number of conditional structures. As a result of experimental data processing, regression equations were obtained that describe the dependence of the algorithm execution time on the number of joins. The developed algorithm and class library make it possible to work with the description of the geometry of the object under study as a set of parameterized primitives and educe the time spent on the formation of the description of the computational domain by up to 27%.

Published: January 2023

The article deals with the issue of organization of transport services in the territories of cities located in the harsh conditions of the cold climate in the Arctic zone. The hypothesis of the study is that uncomfortable weather conditions affect the mobility of the population and form a special behavior of the population with minimal time spent in the open air. Also, people's transport behaviour will depend on the level of development of transport infrastructure that provides access to urban areas. As an evaluation criterion, the time of accessibility to the city centre as the focus of the population's labour trips was chosen. Using the example of three cities located in the Arctic zone, isochrones of accessibility of the urban centre by road and passenger transport, as well as on foot using GIS were shown. As a result of the study it is highlighted that the current transport system of the cities does not meet the transport demand of the population, taking into account the characteristics of climate and stay in open space: there is a problem of excessive use of personal transport, lack of development of passenger transport, low quality pedestrian traffic. Based on the results of the study, the main directions for the sustainable development of cities and their transport systems for the Arctic conditions have been formulated.
Advancing a political ecology of global environmental discourse
Authors: Bagdasaryan Tatyana , Kaneeva Anna
Published: January 2023

The role of ecology within political ecology remains an on-going discussion. A range of methodological approaches characterize political research, including political-economic analyses, historical analyses, ethnography and discourse analusis. In the field of general scientific knowledge, speech is traditionally considered as one of the global problems. To this day, since antiquity, language, speech and the word remain comprehensively studied problems. The direction that intensively analyzes the problems of speech communication is pragmalinguistics. The main task of pragmalinguistics is to study language in its pragmatic function as a means of influence. The most important tool for influencing consciousness is the language. Properly submitted information has a great influence on a person, the way of thinking and actions. The article deals with speech impact of the 44th USA President, Barack Obama. Speech impact is reduced to "pre-planned transformations in the "field of meanings", where the result is a changed perception of the audience. It refers to people's personality and behaviour in order to form and regulate their behavior. The purpose of speech influence is to regulate social, interpersonal relationships and mental states of the interlocutors. This speech effect occurs automatically and intuitively. This action in pragmalinguistics is called a speech strategy of hidden influence. The strategy implies a certain kind of speech behaviour that actualizes the intention of a particular author in a specific speech situation. Using certain language resources in the process of communication, a person can control the actions of other people.

In the context of the dynamic transformation of socio-economic conditions, the aggravation of the demographic situation, the increasing influence of modern world trends in the fashion and beauty industry on the labor market (the emergence of new professions, and within existing professions, new competencies), additional professional education is increasingly gaining the status of a priority direction for the development of an educational institution of higher education. Additional vocational education is presented as one of the promising areas for the development of educational activities, an important component that allows integrating different levels and forms of education in order to have a more flexible educational trajectory. The main criterion for the quality of education in the fashion and beauty industry should be the existence of a system that ensures its compliance with the changing needs of the industry and the formation of personality in all its manifestations.

The article gives a brief description of the new conditions of human life in the world, characterized by the search for optimal and effective resources for sustainable development. The relevance of the topic is due to new require-ments for society and for a person. New conditions create new problems in solving the problems of training specialists who are able to work productively in a digital society. The purpose of the study was to identify the degree of readiness of young people of the "digital generation" to adapt to the new educational environment, the perception of new formats for the digital transformation of the education system. The analysis of the results of this study can contribute to the development of new didactic principles in the field of the use of digital technologies. One of the ways to overcome the conflict in the implementation of new ideas for the sustainable development of the economy, society and the professional training system is the development of a new scientific direction - digital didactics. This direction provides tools that explain the specifics of such components as: construc-tivism, operationalism, technicalism, pragmatism, reductionism, utilitarianism. Using the method of large-scale monitoring and analysis of respondents' answers, we found out that today the "digital generation" is more ready for digital transformation than the carriers of professional and academic knowledge. Over-coming intergenerational contradictions is becoming one of the main problems of modern society and the education system.

The purpose of the article is to assess the impact of digitalisation of the urban environment on the consolidation processes taking place in urban communities. The authors emphasize that digital technologies and services, social networks and messengers integrated into the urban space contribute to the development of alternative types of sociality, solidarity, subjectivity and consolidation of urban communities. The empirical basis of the article is the data of the sociological study “Social consolidation of urban communities: opportunities and limitations in the conditions of digitalisation of the urbanised environment”, conducted by a team of authors of the Belgorod State National Research University in 2022. As part of the study, N=1500 residents of the cities of Belgorod, Voronezh and Kursk regions were interviewed. To gain in-depth knowledge about the subject of the study, an expert survey was conducted (N=50), as well as a series of focus group interviews among 6 social groups: entrepreneurs, pensioners, municipal employees, youth, state employees and the unemployed. The total number of focus group participants is 57 people, the age range is 18-69 years, the gender composition is 34 women and 23 men. The theoretical analysis carried out, as well as the empirical data obtained, allowed us to identify some of the most significant risks of digitalisation that have negative consequences for social consolidation in an urbanised space: digital inequality, blurring of identity boundaries, multiplication of social statuses, technostress, increasing the possibility of controlling the private lives of citizens, loss of live communication, expansion of manipulative practices (dissemination of misinformation, unreliable rumors, post-truth or half-truth).

During the past years, many kinds of research have been done in order to reduce the cost of transportation by using different models of the vehicle routing problem. The increase in the amount of pollution caused by vehicles and environmental concerns about the emission of greenhouse gases has led to the use of green vehicles such as electric vehicles in the urban transport fleet. The main challenge in using electric vehicles with limited battery capacity is their long recharging time. For this purpose, several recharging stations are considered in the transportation network so that if the battery needs to be recharged, the electric vehicle can recharge and complete its journey. On the other hand, due to the limited amount of the electric vehicle’s energy, the fuel consumption of this fleet is highly dependent on their load, and it is necessary to consider their load in the planning. In this article, the problem of routing electric taxis is presented considering the economic and environmental aspects of implementing electric taxis for city services. Despite other studies that have only focused on reducing energy consumption or minimizing distance traveled by electric vehicles, for the first time, the problem of urban electric taxi routing has been modeled by considering different types of electric taxis with the aim of achieving the maximum profit of this business. The use of a heterogeneous fleet in this study leads to wider coverage of different types of demand. Therefore, a mathematical programming model is presented to formulate the problem. Then, several problem examples are designed and solved for validation purposes, and the simulated annealing algorithm (SA) will be introduced and used to solve large-scale problems.

Telemedizinische Unterstützung der feto-neonatalen Versorgung
in einer Region – Teil II: Strukturelle Voraussetzungen und
Anwendungsbereiche in der Neonatologie

Telemedizinische Infrastruktur zur Patientenbeurteilung, -versorgung und
-nachbetreuung sowie dem interdisziplinären Austausch kann dazu
beitragen, auch außerhalb von spezialisierten Zentren eine wohnortnahe,
höchsten Qualitätsansprüchen genügende
Patientenversorgung sicherzustellen. In der Neonatologie wird die
einrichtungsübergreifende, synchrone audio-visuelle Kommunikation
insbesondere im anglo-amerikanischen Raum bereits seit vielen Jahren angewandt.
Anwendungsgebiete umfassen dabei die Gebiete der erweiterten neonatalen
Erstversorgung und Reanimation, spezifischer diagnostischer Anwendungen, z.B.
des ROP-Screenings und der Echokardiografie sowie der elterlichen Betreuung,
regelmäßiger telemedizinischer Visiten und der fachlichen
Weiterbildung medizinischen Personals, insbesondere unter Nutzung von
Simulationstrainings. Für die Implementierung solcher telemedizinischen
Infrastrukturen müssen bestimmte organisatorische, medizinrechtliche und
technische Anforderungen an Hardware, Software und Struktur- bzw.
Prozessorganisation, erfüllt sein. Die konkrete Umsetzung einer aktuell
in Implementierung befindlichen telemedizinischen Infrastruktur für die
Region Ostsachsen wird hier am Beispiel des Zentrum für
Feto/Neonatale Gesundheit (SCFNH) demonstriert. Im Rahmen feto-neontaler
Kompetenzverbünde wie dem SCFNH kann mittels einer
flächendeckend, gut strukturierten und etablierten telemedizinischen
Infrastruktur die medizinische Versorgungsqualität, Patientensicherheit
und -zufriedenheit in einer Region erhöht werden.
