Authors: Lastochkin Denis , Medyakov Andrey , Ostashenkov Aleksey , Kostromin Denis
Published: February 2023

The article presents the results of experimental studies of the micro landform of the cutting area surface as a source of perturbing continuous oscillations of the sprung and unsprung masses of the logging machine. The substantiation of the expediency of studying the microprofile of forest support surfaces in the framework of this work is presented. The characteristic of the objects of the experimental study of the micro landform is given. A new measuring complex and the procedure for measuring geometric parameters of irregularities and slopes of the forest support surface of vehicles were proposed. The justification of the number of measurements in the planning of the experiment is given. As a result of data processing after approximation, normalized correlation functions and their approximation coefficients for the studied types of forest growing conditions were obtained. The obtained curves of normalized correlation functions have a decreasing character, which indicates the presence of a strong correlation on a small section of the length and differ in the steepness of the decline and the distance of the correlation, which varies from 1.8 to 11.6 m for different sections. The obtained approximation coefficients quantitatively characterize the perturbing effect of the irregularities of the natural surfaces of cutting areas of various types of forest growing conditions on the movement of logging machines.

Authors: Valge Aleksandr , Sukhoparov Alexey , Papushin Eduard
Published: February 2023

The article presents a comparative analysis of three common breeds of dairy cattle in the Leningrad Region – Ayrshire, Holstein and Black-and-White in terms of average annual milk yields per head, milk fat and protein content and methane emissions. The indicators were compared by a method, which tested the hypothesis of the equality of two means at the level of some error (5%). Holstein cows had the highest annual milk yields; those of Black-and–White cows were 15.24% lower in average, and those of the Ayrshire breed were 26.64% lower. The Ayrshire breed demonstrated the highest milk fat content; the Holstein and Black-and-White breeds – 1.07 and 1.08 times lower, respectfully. The best average protein content was 3.27% in the Ayrshire breed; the Black-and-White breed had 1.03 times lower protein content, and the Holstein breed had 1.04 times lower protein content. The Holstein breed had the highest methane emission of 0.185 t/head/year. Based on the indicators of productivity and milk fat and protein content, it seemed reasonable to divide all the farms in the Leningrad Region that worked with the considered breeds into 4 groups by applying a discriminant analysis. With a more detailed analysis of both individual breeds and when they are considered together, it makes it possible to determine the effectiveness of their housing on a farm at the regional level.

Authors: Kondsrashova Elizaveta
Published: February 2023

Quality and quality assessment are key indicators in many fields. There exist various interpretations of the quality concept, such as technical, legal, and economic definitions. The fundamental aspect of technical systems is the quality problem, and there are different ways to assess quality. This paper examines the relationship between quality and reliability that forms the basis of the safety property and offers a quality assessment that relies on system reliability characteristics using a mathematical methods. Reliability is influenced by random concepts and events, such as the moment of failure. Costly long-term reliability tests on a large number of products are required to determine whether a particular object is suitable. As an example, the reliability of the redundant recoverable system is considered. Reliability influences the security property. Failure of an object decreases the values of the remaining properties dramatically. The theory of random processes, including the use of the theory of Markov processes, is a rational mathematical technic for solving reliability problem. Quality assessment tasks can also be attributed to management tasks, which are becoming increasingly popular in various areas. As an example, the reliability of the redundant recoverable system is considered. The paper uses the generally accepted concepts of the probability, reliability function, failure rate, etc.

Published: February 2023

The influence of anthropogenic and natural factors on the content of lead in the surface horizons of coastal soils and bottom sediments in the south of the Kamchatka Territory was studded. It was revealed that no significant excesses of acid-soluble forms of lead were found, however, a gradual increase in the content of this element in urban soils is observed. The most likely reason for the content of lead in the soils of this area can be considered pyroclastic material, which prevails in the composition of fine earth.
The place of sustainable development in ESG risks formation in banking sector
Authors: Tashtamirov Magomed
Published: February 2023

Environmental, social and governance (ESG) issues as well as related opportunities and risks are becoming increasingly relevant for financial institutions. For banks, sustainability is not only an ethical issue, but may soon become an economic and existential one, generating a new kind of risk - ESG risk. Banks must approach ESG risk in a comprehensive way by incorporating it into their risk management systems. This process includes adjusting business and risk strategies, and related risk appetite statements, as well as ensuring full transparency. While ESG risk is not a completely stand-alone type of risk, it affects financial and non-financial risks present in the bank to varying degrees. Consequently, risk management methods and processes must be modified to take into account the complex causal relationships between risk types. This involves the use of risk measurement/assessment techniques in the bank management and change processes, as well as in stress testing. In addition to incorporating ESG into the risk framework, banks need to consider related issues in product development, pricing, and sales decisions. In addition, proper consideration of ESG risks in a wide range of change processes is vital to improving profitability. Regulators, rating agencies and other parties around the world are showing increased interest in this topic, leading to increased reporting requirements and needs. This constant stream of new regulations poses serious compliance challenges for banks. This paper explores these issues. It examines ESG factors and sustainability issues in the banking sector, highlights the opportunities to embed these considerations throughout the risk management process, and provides parallels that can be used to learn from the COVID-19 crisis. This article proposes a holistic approach to ESG risks in risk management.

Authors: Jargalsaihan Bolortuya , Orlova Nadezhda Al. , Suzdaleva Antonina L.
Published: February 2023

The Erdenet mining and processing facility (Mongolia) develops a large copper-molybdenum deposit. The volume of waste in the tailings dump of the enterprise reaches 600 m. m3and its area is more than 1300 hectares. Quarries and tailings pits release significant amounts of persistent pollutants into the environment. They penetrate groundwater and surface water and also spread as dust. The results of comprehensive geochemical and geoecological studies indicate the irreversible anthropogenic transformation of the area. In 25 years, the operation of the Erdenet deposit will be terminated. Mongolian government decided to develop a “Concept of the program for closure of the enterprise, and further development of the area”. Based on the results of this research, it is proposed to identify several areas and develop special renovation projects for each of them. An enterprise for the production of construction materials can be created on the tailing’s dumpsite. Companies extracting residual amounts of valuable elements from waste can be profitable. The network of transport communications of the deposit can ensure the operation of facilities in areas of mining landscapes and technogenic geochemical anomalies. After planning the terrain and covering the surface with insulating materials on these sites, a technology park can be organized. Implementing these projects as part of a single program will provide jobs for the Erdenet residents, and the budget revenues generated by their operation will allow for the renovation of the urban area.

Published: February 2023

In the age of rapidly developing information technologies, when the process of informatization has long touched almost all aspects of human life, it is impossible to imagine a single company that would not use a computer network for its functioning. And also with the development of the software and hardware infrastructure of companies, security requirements are growing. But business development through the introduction of the Internet only increases the number of threats associated with the availability, integrity and confidentiality of information. The development of antivirus software, intrusion detection and prevention systems does not fundamentally change the statistics on the number of attacks on enterprises. The number and variety of attacks on information systems is growing every year, and financial losses from the introduction of computer viruses and unauthorized access to the system are growing proportionally. Artificial intelligence (AI) is present in all areas of our activities. Whether it is a household area or a commercial one. In this regard, the use of AI in the fields of information security is more often observed, which is a promising area of research. The article describes the ways of possible application of artificial intelligence methods in the field of information protection, and also proposes an algorithm for the system of information protection from abnormal requests. The use of an artificial immune algorithm makes it possible to increase the effectiveness of threat detection by comparison with existing analogues. A distinctive feature of these methods is the ability of these systems to solve multidimensional problems of enormous computational complexity in real time.

Published: February 2023

An important role in the organization of production sites is played by the security of information for the process of planning the management of the production site. Information security is a very important component of any information system used on the production site. Improving the quality of information system security can be achieved only by a set of data protection measures. The results of the implementation of these measures should provide a clear picture of the information system used, about users, about the separation of powers, etc., which will allow making the right management decisions in the event of an intrusion into the system. Improving the security of information systems, taking into account modern requirements of information security policies, involves the development of data protection concepts and the introduction of the latest encryption methods into the information system. The paper presents the concept of building an information system using data encryption based on SSL encryption. SSL — Secure Socket Layer, the level of secure sockets. SSL encryption is characterized by the creation of a cipher with a public key. This allows you to authenticate the user and the server by resorting to digital signature technology. In addition, this is how the session key is generated to develop a fast symmetric cipher algorithm, which allows you to encrypt a large mass of information.

Authors: Feofilova Anastasia , Fialkin Viacheslav
Published: February 2023

The modern development of transport and road engineering is aimed at the design of transport systems. The sustainable development of territories cannot be imagined without the appropriate transport information content, which includes the services of intelligent transport systems. Management of transport demand and mobility based on a service approach is the future of transport systems, affecting the quality of society development. A conscious perspective of intelligent transport systems (ITS) projects is the development of mobility services. One of them is providing road users with information that encourages them to take a certain action, resulting in a spatial or temporal redirection of traffic flows. A specialized ITS subsystem that controls traffic near objects of traffic attraction by informing about the place of comfortable waiting for the exit and the time of comfortable departure from this object is understood as a system of motivational control of exit transit. The system under consideration is formed in order to prevent a decrease in the capacity of the road in the area of operation of this object and is not intended to reduce the total intensity of the traffic flow at the exit from the object. It provides only a temporary redistribution of exit flows of road users from the object of traffic attraction and the coordination of the moments of these exits in accordance with the current (and predicted) load level of the main highway. Delays of vehicles and the value of unsatisfied demand are taken as performance indicators.

Authors: Novikov Ivan , Degtyar Andrey , Lazarev Dmitriy , Zagorodniy Nikolay , Makhonin Vitaliy
Published: February 2023

Road traffic accidents (hereinafter referred to as accidents) are currently a significant problem in the field of road safety in the Russian Federation. In addition to significant material damage, they often entail human losses. In this regard, the issue of investigating an accident is acute, as well as conducting road transport examinations. Modern calculation models do not always allow to determine the mechanism of an accident comprehensively and fully, especially at the final stage of the mechanism, when the vehicle continued its movement after interacting with an obstacle. The task becomes more complicated in cases where the movement of the vehicle did not have adequate calculation models in the specialized literature for specific (particular) cases of movement. Therefore, the construction of a functional universal computational model of complex vehicle movement based on basic physical principles within the framework of road transport expertise is an urgent task.
Ethnic stereotypes in the assessment of transport infrastructure

Published: February 2023

The assessment of transport infrastructure is one of the significant criteria for a foreigner who chooses another country as a place of work or study. This article is aimed at identifying and scientifically describing ethnic stereotypes in the assessment of transport and transport infrastructure of the host country, analyzing the elements of ethnic consciousness involved in the formation of prejudices towards foreign culture or everyday phenomena. Since any ethnic stereotypes are "fragments of contacts" between peoples, their assessment in terms of historical and cultural interaction seems important and timely. Ethnic stereotypes in the assessment of transport infrastructure have a significant impact on the formation of the image of the country and affect the process of social and cultural adaptation of a foreigner. Research carried out in this direction makes it possible to find effective solutions to specific problems and to take into account the specifics and the influence of the human factor on the artificial environment, and the transport environment is part of it. Given the diversity of real ethnic groups, which include traffic users, it is necessary to raise the issue of developing verified programs of social and cultural adaptation for various categories of foreign citizens.
Tourism and transport infrastructure: an analysis of ethnic preferences
Authors: Pozdnyakova Alina , Dmitrieva Darya , Kalita Marina , Karasu Kağan
Published: February 2023

Despite the restrictions caused by the COVID-19 pandemic and unfavorable foreign policy factors, tourism remains attractive to the population of many countries. The desire of a person to “move” in order to see something new, to feel what representatives of other cultures feel, is natural, in line with the logic of the historical development of peoples, and should be welcomed and encouraged at all levels of the state system. The transformation of travel into a mass phenomenon (including travel for tourism purposes) is largely due to almost revolutionary changes in the transport system. In modern conditions, the traveler is more focused on the independent choice of the tour, the alternative ways and means of transportation in an unfamiliar country. This imposes an additional burden on public transport, which must be taken into account when analyzing the potential of the transport infrastructure of the host country. In the main areas of analytical work, special attention should be paid to identifying social preferences of foreign travelers in the field of transport, determining priorities when choosing a travel method. In this regard, the following are relevant: a) the motives for choosing a mode of transportation / mode of transport by a tourist; b) the relationship of ethnic preferences and expectations when choosing a transport service; c) assessment of the emotional characteristics of the choice. Consideration of these issues and some conclusions obtained as a result of experimental work are presented in this paper.

Published: February 2023

The method of strengthening the soils and foundations of transport structures used for their preservation, especially buildings of architectural and historical value, as well as during mass renovation in large cities in cramped conditions with high density of existing buildings, is considered. The method of constructing a horizontal distributor by pushing through round-section sleepers in the form of steel-reinforced concrete elements made of pipes filled with concrete is considered. In the article, the dependence of the radius of the compacted zone on the initial characteristics of the soil density and the diameter of the pressed pipe concrete element is analyzed. The method of installing a pipe-concrete horizontal distributor for simultaneous strengthening of the foundation and soils is considered, as well as it is the most environmentally friendly and does not negatively affect the surrounding buildings and structures. An assessment of the change in the height of the surface discharge of the foundation soil is presented, which allows to regulate the process of leveling the deformation of the building as a whole.
Trolleybuses and trams in the urban public transport network of Russian regions: problems and prospects
Authors: Grigorieva Olga , Nikulshin Alexander
Published: February 2023

This study covers the problems and prospects of integrating trolleybuses and trams into the public urban transport network of the Russian regions, to the analysis of the relevant experience of individual cities of the world. As part of the implementation of the national project "Safe High-Quality Roads", the regions are financed to modernize the rolling stock of trolleybuses and trams, expand the network of routes, and create modern infrastructure. The study identified the problems of transition to electric public transport, typical for Russian regions and individual foreign cities. In most cities of Russia, the fleet of trolleybuses and trams has drastically decreased compared to the Soviet period, tram lines often interfered with traffic due to increased urban traffic and were dismantled, the infrastructure and rolling stock are worn out and do not meet safety requirements. Abroad, city authorities face other problems: equipping trolleybuses and trams with security systems that allow them to avoid collisions with pedestrians and collisions with other city transport, equipping rolling stock with on-board batteries with recharging while driving, creating low-floor models of trams and trolleybuses. Thus, the task of switching to electric public transport is common on a global scale, but the problems that the city authorities of Russian and foreign regions need to solve differ significantly.
On stability of motion of unbalanced gyroscope
Authors: Titova Tatiana
Published: February 2023

In this paper we consider the stability of motion of an unbalanced gyroscope with a flexible shaft in gimbal suspension.Gyroscopes are used to control the stability of boom tower cranes. First, we consider the linear Hamiltonian systems of differential equations. The Hamiltonian systems arise in transportation problems. We prove several properties of the Hamiltonian matrix. Next, we consider the normalization of Hamiltonian matrix. We solve the system of matrix equations to find the generating function of the canonical transformation. Further, we find the symmetric solution of nonlinear algebraic matrix Riccati equation in one case. We propose the analytical method for solving this equation. Further, we investigate the motion of gyroscope. We consider the system of equations of motion of the gyroscope rotor and frames in the first approximation. We consider eigenvalues of characteristic equation corresponding to the motion equations. We obtain stability criterion in several cases.

Authors: Prokopiev Anatoly , Salimgaraeva Regina , Safin Ruslan
Published: February 2023

Since the appearance of the first automobiles, the wood due to its advantages, such as ease of processing and noble appearance, has firmly entered the automotive world as a material for body engineering and interior finish. However, fairly rough operating conditions of the automobile (variable humidity, possible contact with water) require protection of wooden elements. This paper provides the results of a study of modified wood by acetylation with acetic acid. Experimental data showed that moisture absorption decreased depending on the duration of wood veneer treatment in glacial acetic acid from 43% to 21%. An increase in the limiting wetting angle value was found - 460, 580 and 690 as compared with the control sample (100). The mass gain after keeping the samples for 6, 12, 18, 24 and 30 hours in glacial acetic acid ranged from 1.2 to 4.8% by mass as compared to the control sample (due to the introduction of acetyl groups). Based on the results of acquired data, it can be concluded that this method of wood treatment allows reducing moisture absorption, minimizing swelling and, as a result, increasing the shape stability of wooden products for the automotive industry.

Zoombombing: causes and preventions
Authors: Siddiqui Kamran , Ahmad Shabir
Published: February 2023

This paper aims to share the Zoombombing: a new phenomenon that emerged during COVID-19, its causes, and measures to prevent Zoombombing. Finally, it provides recommendations to prevent such incidents. Zoom emerged as the most popular alternative teaching tool during COVID-19. However, even though Zoom has utilized state-of-the-art encryption methods, it has underestimated privacy expectations among its exponentially growing customer base. Zoom has many options settings for users to customize and secure their videoconferencing platform to minimize Zoombombing. However, some users overlook these security features, which leaves them vulnerable to offensive material displayed by attackers in a virtual classroom setting. Furthermore, most Zoombombings were made by insiders who had legitimate access to Zoom meetings, particularly students in high school and college classes. To reduce Zoombombing, teachers can enable settings, such as waiting room, restricting access to screen-share, and physical reporting. Moreover, severe institutional punishment for the attackers and their insider supporters can discourage such activities.

The paper discusses the main approaches to assessing the qualitative state of soils. ‘Normal’ and ‘normative’ crop yields are calculated. Comparison of the obtained calculated yields, depending on the properties and composition of soils, with the actual yield is made. It was concluded that the yield decreases when moving from not prone to degraded soils. Using the methods for ‘normal’ and ‘normative’ crop yields, the production value of soils was assessed. The indicator of ‘normative’ yield is analyzed taking into account the value of the agroecological potential. It is concluded that the use of ‘normative’ yield is the most appropriate for assessing the production value of soils in agricultural production, since this method reflects the difference between soils of better and worse quality. For comparison, the data on determining the assessment of the qualitative state of soils according to the bonitet score of agricultural crops are given. Studies have shown that due to the manifestation of degradation processes in soils, the production value of soils is currently decreasing. It was concluded that the dynamics of the structure of the soil cover, composition and properties of soils led to the lost profit due to the short productsreceived.

The fourth industrial revolution is one of the most ambiguous stages in the evolution of the world economy: the basis of its unpredictability is the involvement in the orbit of all the states of the world, regardless of their level of economic and technological development, while the key postulate of Industry 4.0 - information openness and transparency of socio-economic systems - has become the source of the appearance of a new concept of not only managerial, but also military and political thinking of elites. The business model of the digital economy, as the main product of the fourth pro-industrial revolution, is almost all built on extreme parameters: on the one hand, there is a pronounced motivation for the "availability of personal data and the active development of institutions of digital commonwealth of countries, encouragement for cross-border digital commonwealth and association, on the other hand, today there is a growing separatist sentiment and deinternationalization of countries due to a "domino effect" in the world economic system, in which the countries most involved in the digital dialogue become victims of their own openness and blind adherence to the ideals of scientific and technological progress. The specified contradictions of key ideas of digital economy are the basis of scientific research of national security of financial system of the Russian Federation taking into account escalation of military-political and economic tension in the international dialogue with EU and USA and difficult to predict scenarios of further developments.

The article discusses the problem of determining safe work experience in conditions of increased intensity of hard work. It is especially relevant in construction industry. The need for an objective analysis of industrial accidents is an urgent task not only for the prevention of injuries, but also for improving environmental safety, interpreted as occupational risk management in order to protect the health of people of active working age. The research methodology was based on the analysis of the characteristics of the occupational diseases risk, depending on the level of existing harmful production factors, as well as the length of service. Occupational risk is directly related to the dynamics of changes in harmful and hazardous production factors during an employee's work experience. This risk gradually increases nonlinearly over the course of the employee's work experience, and in the experience sector the risk begins changing at an increasing rate. The new system for assessing working conditions introduced in 2014 in Russia, although it helps to reduce the annual increase in risk, but cannot provide completely environmentally friendly and safe working conditions and acceptable risk (R). The environmental safety of production activities is a big question and is at high risk in the construction industry, in particular due to the huge number of concealment of occupational injuries, violations of the regenerative capacity of the human body, as well as the extension of the retirement age to 65 and 70 years. Therefore, it is required to introduce a mechanism (model), providing a real system for assessing working conditions.

The Russian practice of marketplaces is often associated with free transport delivery of purchased goods, as opposed to international studies, where the driving factor is a competitive price and a convenient purchase process. The study showed that 83% of marketplace buyers are convinced that the cost of delivery is shared between the seller of the goods and the marketplace itself, and the client gets it for free. International studies indicate that the desire to see the price of delivery as a separate item is typical for rational buyers. Therefore, the initial conclusion was the confirmation of the emotionality of marketplace buyers, as opposed to the rationality of buyers of branded online stores. However, a study conducted by the authors showed that one of the key factors influencing the purchase of goods on marketplaces is the ability to compare prices from different sellers, which is a sign of the rationality of the purchase. Thus, we can conclude that the initial impulse to buy on the marketplace is most often just rational, but the buying process itself can be subject to emotional decisions.
