Authors: Kovalev R N , Enaleeva-Bandura I M , Vasilijev V I 
Published: October 2020

Abstract
The main purpose of the paper is to develop a mathematical model for planning the transport network in the territory of the forest fund based on the criteria of ecological and economic efficiency. Setting the goal is caused by the fact that, despite the urgency of the problem of ensuring effective ecological, social and economic development of forest fund and the existing scientific achievements in this field, both in Russia and abroad, the scientific base has accumulated a small amount of research that considers forest transport systems as one of the main factors that contributes to achieving the goal of sustainable development of forest territories in modern conditions of management. The complex analysis of the ecological and economic efficiency of transport network planning in the forest fund territory is only indirectly present in the scientific literature and is local in nature. The paper presents an approach according to which a qualitative criterion is formed for evaluating the effectiveness of the transport network functioning on the territory of the forest fund as achieving the maximum of all potential revenues from the use of various types of forest resources and the ecological potential of the territory on the basis of the planned network.

Abstract
Like all evolving economies, Pakistan’s urban transport and commute problem is one of the tenacious subjects of the time which needs to be judged and evaluated. With mounting congestions on roadscausing from an upturn in number of privately owned vehicles, urban commuting problem is aggravated so abruptly in all the major cities of Pakistan. The resolution of this research was to study the transport infrastructure in Pakistan and the conditions of traffic and commute in the country while focusing its major cities. Respondents’ perceptions/responses on the proposition of this study were recorded for reaching the empirical findings on urban transports and commute problems and their effects. 1000 respondents were selected from all major cities those wereaffected during the rush hours. The findings confirmed that the traffic and commute conditions are very critical problems in all major cities of Pakistan. The present conditions of traffic and commute pave the way for effecting employee productivities, while traffic congestion promotes psychological problems in public in general. The findings recorded that, in country the circular railway network development reduces the dependency of general people on buses and other means of commute further, this circular railway system eliminates traffic congestion in all major cities of Pakistan. Findings proposed that the better commuting infrastructure (low types roads, high types roads, under passes, bridges, and fly overs) can save the time of public while eliminating the traffic jams in all the major cities. This research recommends that the eliminations of encroachments may also pave the way for reducing traffic and commuting congestions. It was proposed empirically by this study that a good welcome for traffic rules by public may help to manage commuting on the roads as the whole.

Abstract
The constant increase in the number of cars in cities causes transportation problems that make it necessary to optimize the road network so as to satisfy the transport needs of the city. In this regard, modeling and optimal planning of the road network are of great importance. Motion modeling is a widely used method of traffic studies, modeling, planning and development of transport networks and systems. It represents the construction of a working model that reflects the similarity of properties or relations with the real problem under consideration. Modeling allows makes possible to study the complex tasks of traffic not in real conditions, but in the laboratory. In a more general sense, modeling can be defined as a dynamic display of some part of the real world by building a computer model and moving it in time. Simulation models of traffic aimed at modeling real transport operations can be divided into three categories: microscopic, macroscopic and mesoscopic modeling. These methods of modeling traffic flows are designed to solve the most common transport problems. In most cases, models allow determining such parameters as traffic intensity, average speed, delays and time loss. This study is an analysis of existing traffic flow simulations in terms of their functions, limitations, and application by various criteria.

Authors: Abu-Saleem A , Kochetkov I D , Rustanov A R 
Published: October 2020

Abstract
The paper studies the geometry of the Riemann curvature tensor of generalized Kenmotsu manifolds. In this paper, several identities satisfied by the curvature tensor of generalized Kenmotsu manifolds are obtained. Two identities are distinguished from the obtained identities, called the first and second additional identities of curvature of the GK-manifold. Based on additional identities, two subclasses of GK-manifolds are distinguished, and a local characterization of the distinguished classes is also obtained. It is proved that the distinguished two subclasses of GK-manifolds coincide and have dimension 5. In addition, it is proved that the class of distinguished manifolds coincides with the class of almost contact metric manifolds obtained from a cosymplectic manifold by a canonical concircular transformation of a cosymplectic structure of dimension 5.

Published: October 2020

Abstract
The problem of high traffic loads of vehicles is typical for most countries of the world. The current situation leads to significant delays in vehicles due to traffic jams, which negatively affects the efficiency of cargo and passenger transportation. In addition, the environmental burden is increasing due to increased emissions of harmful substances into the atmosphere. An increase in the number of road traffic accidents and an increase in the severity of the consequences of accidents is another sad factor caused by the increase of cars. In order to reduce the negative aspects associated with reducing road safety in most countries of the world, emergency assistance systems have been developed and are constantly being improved in a case of a car accident. Such systems include the European ECall, NEXCO Central, developed in Japan, ERA-GLONASS, deployed in the Russian Federation and a number of other modern developments. These systems allow real-time monitoring of the traffic situation using GPS navigation and in the event of an accident, timely inform the relevant services. The introduction of an automatic system for reporting a traffic accident can reduce the response time of emergency services and reduce the severity of the consequences of accidents. The article considers the possibility of expanding the functionality of the ERA-GLONASS system by installing additional sensors for shock, moisture, flame and the vehicle’s spatial position after the accident, which will provide emergency services with extended information about the condition of damaged cars after a road accident. Equipping vehicles with such sensors will allow the contact center operator to assess the severity of the consequences of the accident correctly and coordinate the activities of rescuers even before arriving at the scene. Improving the ERA-GLONASS system will have a positive impact on the efficiency of the first aid for victims of a traffic accident and will qualitatively increase its level.
Assessment of the decisions made by the marine vessel navigator
Authors: Fadyushin S G , Vereshchagina E A , Pafnuteva Y V 
Published: October 2020

Abstract
The paper deals with interdisciplinary scientific research that lies in cognitive psychology, information technology and navigation, and is devoted to the relevant topic of navigation - vessel navigator’s decision-making. It reflects the results of theoretical research on the formalization of certain aspects of human mental activity in relation to solving navigation problems. The specific nature of this paper lies in navigator’s inclusion into the ship management which leads to the need in simultaneous consideration of psychological characteristics and ship manageability characteristics. Thus, navigator’s decisions are subjective and consequently difficult to formalize. The purpose of the research is to formalize, i.e. to mathematically describe the quantitative assessment of navigator’s decision-making. Author’s method of probabilistic sense evaluation is used in this research. The semantic space structure, which channels navigator’s decision-making, is represented as the model of a semantic prism. The results are adapted to the concepts of navigation and may be of interest to specialists in ship traffic control automation, artificial intelligence, creation of intelligent control systems and navigation safety.

Authors: Dement’eva M E , Dement’eva A V 
Published: October 2020

Abstract
The article explores the principles of organizing an integrated system of vertical transport to ensure the safe operation of high-rise buildings and the possibility of improving it. The reasons for the violation of the safety of using a tall building and the factors for their prevention and elimination were analyzed. The relevance of the study is justified by the non-zero probability of emergency situations and possible human casualties. On the example of a warning and evacuation control system in the event of a fire, methods of intelligent control of human flows are considered. The aim of the study was the proposal to introduce additional tools to make the vertical transport system safer and faster in the event of any emergency. The objective of the study was to calculate the rationale for these proposals. The calculation results confirm the effectiveness of the proposals, which will lead to a reduction in the time of evacuation, reduction of consequences in the form of stress and injuries for people.
Modified swarm algorithm «ant tree» in the problem of diversification of tractor resources spaces
Authors: Lebedev Boris K , Lebedev Oleg B , Purchina Olga A 
Published: October 2020

Abstract
In this work, the problem of increasing traceability is solved by diversifying trace resources, which consists in using additional areas adjacent to the channels below and above, with a trace layer located above the “over-the-cell” cells. For a single-layer routing uses a new paradigm of combinatorial optimization – ant tree (trees ant colony optimization (T-ACO)), based on the ideas of adaptive behavior of ant colony. The decision tree is used as a decision search graph. An agent for the decision search graph does not create a route, but a tree, which in its structure coincides with the representation of the solution to the trace problem in the «over-the-cell» region. This eliminates the use of additional transformations in the decoding process of decisions that allow interpretation of decisions in the form of trees and allows you to discard a lot of «illegal» solutions, which leads to an increase in the quality of the solutions obtained. Using the tracing procedure in «over-the-cell» based on the ant algorithm allows you to unload the channel by 15-20%. The time complexity of the algorithm depends on the number of vertices n of the decision search graph, the number of agents y, the number of iterations l, and is defined as O (n2·l·y).
Terminological modelling of the aviation terms system in the context of globalized information space and security of aviation industry
Authors: Burlakova Iryna , Sibruk Anastasiia , Khalinovska Liudmyla , Sibruk Viktor 
Published: October 2020

Abstract
Ukrainian aviation terminology, which denotes the concept of this field of technology, belongs to the general technical terminology of the Ukrainian language. Solving a number of problems of translation and adaptation of borrowed terms, primarily from English, will lead to the active integration of national terminology to the scientific world. One of the important issues in the development of Ukrainian aviation terminology at the regional and global levels is the quality and adequate translation of domestic terms into the global aviation language called airspeak which is part of the global language - lingua franca (ELF). One of the main tasks of linguistic science is the systematization and generalization of phenomena and the formalization of the laws of their origin and functioning. Terminology has its own specificity, which consists in the fact that a large number of special words is borrowed from other languages by the professional broadcasting, which is connected with scientific and technological progress, cooperation of scientists from different countries of the world. The vocabulary of terminological systems is the most actively replenished and changed. One of the main features of terminological vocabulary replenishment is the use of foreign words and their components for naming new concepts. Classical terms meet the requirements of accuracy, brevity and ensure the uniqueness of the term.
Transport security in terms of digitization
Authors: Sheveleva S , Yakovleva E 
Published: October 2020

Abstract
The authors consider in the article the issue of ensuring transport security in Russia both from the standpoint of the lack of an appropriate approach to formation of educational programs for the training of legal personnel that can meet the “challenges” of scientific and technological progress, and the need for increased attention to the trends of modern scientific research, which serve as a basis for formation of a legislative framework aimed at regulating public relations in the field of fighting crime in this industry. The issue of formation of human resources corresponding to a high level of professionalism, rationality, competence and mobility is indicated by the rapid “complication” of crime in the field of transport infrastructure caused by the development of IT technologies and introduction of robotic controls based on the work of artificial intelligence. One of the solutions to the problem identified by the authors should be creation and implementation of a new training course, the conceptual basis of which should be built on the principle of a modular system, but combine the existing traditional approaches of legal education in order to prepare competitive personnel that can meet the “intellectual challenges” of modern reality, which is a direct reflection of connection between science and knowledge (Scientia est potentia). The publication was prepared as part of the implementation of the state task for 2020. “Transformation of private and public law in the conditions of an evolving individual, society and state” (No. 0851-2020-0033).

Published: October 2020

Abstract
A comparative analysis of concrete without additives and concrete samples containing molybdenum wastes was carried out. The purpose of the work is to identify the effectiveness of the metallurgical waste influence on the physicomechanical properties of concrete, the transportation from the storage site to the concrete plant, and the substantiation of their application areas. This will solve a twofold problem: to solve the problem of industrial waste (by improving the environmental status on the example of North Ossetia-Alania) and expand the range of additives used in the production of concrete. By conducting laboratory tests the physical and mechanical properties of concrete mixtures are determined. To determine the strength characteristics of concrete samples, the IM-1250M testing machine was used. The tests were carried out under the same temperature and humidity conditions. According to the results of the experiments, the samples with molybdenum-scheelite waste showed a higher result of the physicomechanical properties of concrete. As a result of experimental analysis, the influence of metallurgical industry wastes on the strength characteristics of concrete and water resistance, as well as the safety of their use in concrete mixtures, was determined. The use of waste from the metallurgical industry will save natural material, and at the same time clear large areas of these dumps. The use of waste from the metallurgical industry will save natural material and reduce transportation costs, as there are concrete plants near the dumps, which are economically feasible. Thanks to that use it is possible to clear the large territories of these dumps.

Authors: Matevossian Hovik A 
Published: October 2020

Abstract
We study the unique solvability of the mixed Dirichlet-Neumann biharmonic problem in the exterior of a compact set under the assumption that generalized solutions of this problem has a bounded Dirichlet (energy) integral with weight |x|a. Using the variational principle and depending on the value of the parameter a, we obtained uniqueness (non-uniqueness) theorems of the Dirichlet-Neumann problem or present exact formulas for the dimension of the space of solutions. The results of this paper are used in the study of mathematical problems in mechanical models, in particular, in transport models and procedures.

Authors: Gagarin V G , Akhmetov V K , Zubarev K P 
Published: October 2020

Abstract
The logistics of the moisture movement in the building wall is very important. We need to know the movement of moisture from one point to another. Two known moisture transport equations are analyzed. The first one is based on vapor-state moisture movement in sorption wetting zone, and the second one – on combined transfer of vapor and liquid moisture. Their strengths and shortcomings are described. Analytical formula for moisture potential F developed by V.G. Gagarin and V.V. Kozlov is given. This formula allows taking into account moisture transport simultaneously in sorption and ultrasorption wetting zones in a consistent way. Derivation of a new moisture transfer equation based on moisture potential F is given. Benefits of such approach are introduced. Boundary conditions for moisture transport problem are formulated, problem solution by finite difference method using an explicit difference scheme is given. The proposed method is applied to single-layer enclosing structure made of aerated concrete blocks. It is demonstrated that illustrated method takes into account wetting inertia, and allows moisture distribution determination in all enclosing structure sections at any time. Results can be presented as moisture distribution along enclosing structure thickness, or as enclosing structure average moisture variation during a year. It is highlighted that calculation using the proposed method does not require values of separate moisture transfer potentials.

Published: October 2020

Abstract
Ukraine’s social and economic development and its integration into the global community largely depend on the development of transport infrastructure, in particular, on the level of availability of roads. Exactly by development of highways the way out of the world economic crisis started for many countries. Thus, the USA, Germany, Japan, which once identified the development of the road network among the main priorities of economic policy, as a result received not only a developed segment of transport infrastructure, but also stimulated economic growth and achieved positive results in solving the employment problems. Among the urgent tasks of technical progress in road construction, the creation of technologies that will improve the condition of soil and allow reuse. It is known [4], that the soil is used for the arrangement of subgrade and road foundaion, as well as of basic pavement layers, the strength and stability of which affect the riding quality parameters of the road - strength and evenness. The duration of construction and repair of roads depends on the volume of earth works.
