Authors: Balashov Evgeny , Kirillova Ariadna
Published: March 2021

At the present stage, it becomes relevant to search for a new model of tariff formation in the housing and communal services (HCS) in accordance with the scale and significance of restructuring the economy and the conditions of functioning during a pandemic, as well as effective mechanisms for regulating tariffs and reducing the cost of production and provision of services. Despite the progress in improving the tariff policy, determined by the long-term period of the formation of parameters for changing the regulated tariffs and the use of the existing multi-level system of social protection of the population when paying for housing and communal services in the regulation of prices for the organizations of the communal complex, the expansion of methodological approaches to the regulation of tariff policy, the existing system of social protection of the population when paying for housing and communal services, the availability of information on the activities of regulated organizations, the task of accelerating the growth of the Russian economy and the sustainable functioning of housing and communal services dictate the need to consider tariff policy as one of the tools of resource efficiency and find additional sources of funding. The problems systematized in the article require decision-making to eliminate them at the state, regional and municipal levels. The necessity of combining a significant number of separate sectoral documents on the communal sector into a single federal law has been proved, which will regulate and establish unified regulatory and methodological principles for the formation of tariffs and will make this process more transparent. The paper discusses the problems of increasing the importance of the share of the investment component in the tariffs for utilities, as well as factors such as deductions from profits (with their financial stability), raising borrowed funds, selling bonds and systematic audit of their production and economic activities, increasing the transparency of costs.

Published: March 2021

Recent achievements in high-performance computing significantly narrow the performance gap between single and multi-node computing, and open up opportunities for systems with remote shared memory. The combination of in-memory storage, remote direct memory access and remote calls requires rethinking how data organized, protected and queried in distributed systems. Reviewed models let us implement new interpretations of distributed algorithms allowing us to validate different approaches to avoid race conditions, decrease resource acquisition or synchronization time. In this paper, we describe the data model for mixed memory access with analysis of optimized data structures. We also provide the result of experiments, which contain a performance comparison of data structures, operating with different approaches, evaluate the limitations of these models, and show that the model does not always meet expectations. The purpose of this paper to assist developers in designing data structures that will help to achieve architectural benefits or improve the design of existing distributed system.

Authors: Gelver Fedor , Saushev Alecsandr
Published: March 2021

Schematic and algorithmic solutions for the design and construction of ship’s electromotive systems of various purposes are considered. The analysis of the existing structures of electromotive complexes, as well as the types of electrical converters used is carried out. The structure of an electromotive complex based on a transformerless structure with common DC bus-bars is proposed. The main goals of improvement are to increase energy efficiency, reliability and survivability of an electric power plant, and lower weight and size characteristics. The proposed structure of the ship’s electromotive complex allows braking the propellers without using additional braking circuits with the redistribution of energy between the propeller electric machines and the dissipation of braking energy in the working medium - water. An algorithm is proposed and mathematical modeling of braking and reverse modes of a propeller electric installation is carried out. Timing diagrams of changes in torque, rotation speed and power on each of the propellers for the proposed algorithm of braking and reverse of propeller motors are presented. It is shown that the synthesized structure of the electromotive complex makes it possible to reduce the emissions of pollutants into the environment, as well as to save fuel within the range of 10÷15%, depending on the operating modes of the ship in comparison with the existing structures of the electromotive systems.
Prospects of application of mass-produced GNSS modules for solving high-precision navigation tasks
Authors: Karetnikov Vladimir , Milyakov Denis , Prokhorenkov Andrei , Ol’khovik Evgeniy
Published: March 2021

Nowadays, both in the Russian Federation and in foreign countries, the use of global navigation satellite systems (GNSS) for solving various applied problems is an extremely popular solution. Taking into account the current level of development of satellite radio navigation systems, ordinary users have been able to determine their position with a sufficiently high accuracy. However, some tasks require the use of high-precision equipment of geodetic class. Such equipment allows obtaining navigation solutions with an accuracy of better than 10 cm. Unfortunately, the cost of navigation-class navigation equipment is extremely high. Specialists working in the field of satellite navigation are particularly interested in the possibility of using mass-produced GNSS modules to obtain high-precision navigation solutions. In this paper, the possibility of such an application will be considered, taking into account the results of laboratory tests of a mass-produced navigation module.
Influence of a cargo plan on the container ship port turnaround time
Authors: Kuznetsov Alexander , Kirichenko Alexander , Zboinov Alexey
Published: March 2021

Nowadays, with patented technologies for the production of goods, the possibility of reducing their cost in order to maintain a competitive position in the commodity markets is supported by the rational organization of transportation. Thus, the transport component in the final cost of transported goods is reduced. At the same time, when using the same handling, lifting and transporting equipment from a limited number of global manufacturers, the possibility of reducing the cost of transport operations (both shipping and handling, including loading/unloading) depends only on their rational use. One of the mechanisms for rationalizing the loading and unloading operations carried out by container terminals is the rationalization of cargo plans of the serviced container ships. The versatility of their development is determined, first of all, by high requirements for the safety of navigation, which determine the provision of the necessary stability, unsinkability, the absence of a heel and difference that interfere with the work, the required sitting of the ship in the water, etc. On the other hand, the rational placement of containers in the slots and on the hatches covers of the container ships, corresponding to the voyage rotation (the sequence of visiting terminals on the trip in progress), provides an increase in the share of productive movements of handling, lifting and transporting equipment, reduces the required time for a ship to be under loading and unloading operations, which reduces the time of a group of ship trips on a string. Such calculations are complicated by the fact that the handling equipment used during the loading and unloading operations on a separate ship operates conditionally autonomously, each unit - for its own section of the ship (“bay”). Thus, the task can be solved only in a complex manner, coupled with the task of cranes allocation over the berth. The paper studies the issues of cargo planning of liner container ships from the standpoint of reducing the time of ship’s turnaround time due to rational assignment and use of port handling equipment.
Monitoring of the process of safe divergence on the part of an unmanned vessel
Authors: Smolentsev Sergey , Sazonov Anatoly
Published: March 2021

The paper deals with the problem of control of maneuvers in the divergence of vessels. In a situation of dangerous convergence of vessels, one of them must take a maneuver for safe divergence in accordance with the COLREGS (International Rules of Preventing Collision at Sea). In this case, the vessel, which is given way, must maintain its course and speed. However, it must also monitor compliance with the divergence obligations by the oncoming vessel. The problems arising in the case when the vessel, which is given way, is an unmanned vessel controlled by an automatic agent. The reasons are given for the fact that the behavior of the oncoming vessel may differ from what is expected from the agent managing the vessel to which they must give way. For these cases, the criteria are provided by which the agent operating the unmanned vessel can detect the situation of non-compliance by another vessel with its divergence obligations, in order to take timely action to avoid a collision by maneuvering agent’s vessel in accordance with the COLREGS.

Field theory in normal conical coordinates
Authors: Nesnov Dmitry
Published: March 2021

In the scientific literature, the field theory is most fully covered in the cylindrical and spherical coordinate systems. This is explained by the fact that the mathematical apparatus of these systems is most well studied. When the source of field has a more complex structure than a point or a straight line, there is a need for new approaches to their study. The goal of this research is to adapt the field theory related to curvilinear coordinates in order to represent it in the normal conical coordinates. In addition, an important part of the research is the development of a geometrical modeling apparatus for scalar and vector field level surfaces using computer graphics. The paper shows the dependences of normal conical coordinates on rectangular Cartesian coordinates, Lame coefficients. The differential characteristics of the scalar and vector fields in normal conical coordinates are obtained: Laplacian of scalar and vector fields, divergence, rotation of the vector field. The example case shows the features of the application of the mathematical apparatus of geometrical field modeling in normal conical coordinates. For the first time, expressions for the characteristics of the scalar and vector fields in normal conical coordinates are obtained. Methods for geometrical modeling of fields using computer graphics have been developed to provide illustration in their study.
Influence of technological cracks of peeled vener on the shear strength of ultralam bars
Authors: Mironova Stefania
Published: March 2021

The aim of the research is to study the shear strength of laminated veneer lumber (LVL) when working on shear in four different planes. To determine the influence of the presence of technological cracks formed in the peeling process, an experiment was carried out for which four types of samples were used. The load was applied parallel and perpendicular to the glue line and the direction of the peeled veneer fibers. As tests have shown, the technological weakening of peeled veneer reduces the strength properties of a multilayer glued veneer bar, especially for shear along the glue lines and perpendicular to the direction of the peeled veneer fibers, where the maximum number of microcracks is located. The analysis of these microcracks is carried out and their widths are determined. The width of the studied cracks was from 152 to 94 μm. There is no adhesive layer in the microcracks of this building material, which may indicate insufficient wetting of the veneer surface with the adhesive material, or the difficulty of penetration of high-molecular phenol-formaldehyde glue into the cavity of microcracks.

Economic assessment of flood damage
Authors: Miroshnikova Tatyana
Published: March 2021

Flooding is a natural hazard. In this regard, the topic of floodprone area management is being actively explored. The study of this issue is a combination of two aspects - environmental and economic. The economic assessment of the consequences of flooding is a single cost model based on an economic criterion. Characteristics such as flooding depth, flooding duration and flooding rate have the greatest influence on the severity of subsequent damage. Standard damage tables are usually based on some damage versus flooding depth. Assuming that the conceptual basis for estimating damages is the same, the expected damages from flooding might be expected to vary between two countries if the flood characteristics are different and the damageability of properties varies between the two countries. The main factors identified by the authors in the course of the study, influencing the amount of damage from flooding, are: flood resistance group; existing physical wear and tear; flooding level. The damage is considered as a percentage of the decrease in the real value of the object. To improve the accuracy of determining flood damage, a multivariate regression analysis tool with the interdependence of influencing factors was selected. It should be noted that the most significant factor is the level (depth) of flooding. The factor of the flood resistance group, which depends on the capital group of the object, seems to be less significant. The least significant factor is the degree of physical deterioration of the object.

Authors: Barkalov Sergey , Dorofeev Dmitry , Fedorova Irina , Polovinkina Alla
Published: March 2021

The article describes the use of digital twins in socio-economic processes using the example of predictive asset maintenance management. For this, the architecture of a distributed forecasting information system is proposed that collects data from digital twins and provides them with a pre-trained neural network model to obtain forecasts about the need for predictive maintenance. The article discusses two types of forecasts - about the remaining useful life and the possible failure of an asset in the considered time window. Computational experiments have been carried out, confirming that the proposed neural network model allows, due to the simultaneous training of solving two problems, to obtain more accurate forecasts than models trained to solve one problem.

The article describes the management model of complex socioeconomic systems, based on the synthesis of information that characterizes economic systems. To summarize the information, it is proposed to use the Rasch model for estimating latent variables. The management structure of complex economic systems is considered on the basis of generalization of system indicators according to the Rasch model. The mathematical basis for solving the problem is described, including taking into account the importance of the criteria. The case is considered when the values of indicators of the economic system are obtained from a variety of information sources. The results of computational experiments are presented, which allow analyzing the main properties of estimates of generalized indicators of economic systems. Computational experiments have shown that estimates of generalized indicators of objects are measured on a linear scale, are highly accurate and resistant to changes in the source data.

Design and implementation of the system to support making medical decisions aid to the population
Authors: Stodelova Ekaterina , Korableva Galina
Published: March 2021

The publication discusses the issues and results of designing an automated system for supporting medical decision-making on issues of antirabic prevention and aid to the population. The need to provide medical care in the framework of preventing deaths from rabies infection and carrying out preventive measures to prevent such infections is relevant not only in the Russian Federation, but also in many countries of the world. Algorithms for providing medical care and carrying out rabies vaccination are complex, requiring certain professional skills from medical professionals, as well as care and accuracy from patients. Therefore, in manual mode, they are time-consuming both in terms of registering information about the treatment performed, and in terms of the speed of forming medical decisions when providing medical care or when correcting violations of previously defined algorithms. For computer support of these processes, an automated system for supporting medical decision-making has been developed using the tools of the Clarion 10 relational database management system. For various categories of patients and citizens undergoing rabies prevention, experts have developed and entered into the database templates of treatment courses, which are assigned by the system after analyzing the clinical data of patients and the initial or repeated fact of their request for help.

Published: March 2021

In the light of the ongoing digital transformation in the world, there has been a significant increase in scientific and practical interest in the problem of human capital (HC) in recent years. This interest bases on the understanding of its key role in the socio-economic life and development of society with a radical change in the technological order at all its hierarchical levels: national, industry, regional, corporate and individual. On the upper levels (national, sectoral, regional) HC is characterized by demographic indicators, characteristics of the level and quality of education, health, living standards, cultural development, degree of scientific and technological scope of the society, degree of mobility when moving from areas with relatively low standard of living in places with higher, etc. The paper proposes a powerful evaluating tool for improving and increasing the human capital measurement, which can serve for increasing the social welfare of society, and transferring the most effective innovative solutions to the economy. The tool is based on mathematical modelling and correlations among HC and non-HC variables.
