Authors: Loganina V I , Frolov M V 
Published: October 2020

Abstract
The laws of moisture condensation in the external enclosing structures of aerated concrete blocks of grades D350-D600, finished with various types of dry building mixtures, are investigated. The mathematical dependence of the temperature of the onset of condensation in the aerated concrete enclosing structure on the thermal conductivity and vapor permeability of the outer finish coating is obtained. It was revealed that when using the developed calcareous composition with the use of ash aluminosilicate microspheres for the finishing of aerated concrete blocks of grades D350–D600, moisture condensation begins at a lower outdoor temperature.

Published: October 2020

Abstract
A method of separately combined analysis of the process of radiant-convective heat transfer through the central part of the double-glazed windows is developed. The problem of heat transfer by radiation through a double-glazed window is formulated and a solution is obtained in an analytical form. The solution is applicable for all types of double-glazed windows with a given number, characteristics and location of low-emission coatings. The possibilities of reducing radiant heat losses through double-glazed windows due to an increase in the number of glasses and the use of glasses with low-emission heat-protective coatings are analyzed in detail.
The influence of micro- and nanodots lubricating and cooling technological means (LCTM) on the process of blade cutting of materials
Authors: Naumov A G , Novikov V V , Naumova O A , Shvetsov I V 
Published: October 2020

Abstract
Improving the efficiency of cutting tools and the quality of the processed surfaces in the course of metal blade processing is largely determined by the intensity of adhesive interactions between the tribo-conjugated surfaces of the tool and processed materials. This is due to the high chemical activity of the juvenile surfaces formed in the process of chip separation in tribo-conjugated contact. As it is illustrated by theory and practice, one of the main mechanisms effecting on the amount of adhesion is the formation of separation lubricant films at the interface between the tool and the processed material by introducing external technological means into the contact zone (lubricating and cooling technological means – LCTM).

Utilizing factor models to simulate emergency shutdowns of power grids
Authors: Polkovskaya M , Buzina T , Fedurina N 
Published: October 2020

Abstract
In the article, based on statistics on emergency outages in the Levoberezhniy and Pravoberezhniy districts of Irkutsk and the sums of average daily temperatures in years 2010-2017 regression models are built. As an auxiliary factor for the models built on values that were grouped by year, the seasonality index was calculated using the “Kassandra” model. In the model, built for values that were grouped by month, a trend was added in addition to the seasonal component.
A retrospective prediction of emergency outages based on the data of the Levoberezhniy district, gathered in April 2020 showed that a model with a trend and a seasonal component gives a more accurate prediction. Since the sum of the average daily temperatures can be considered a random variable, the proposed factor models can be used to predict emergency outages only with some probability. The solution of inverse problems, when the factor value is determined for a given number of emergency outages, can be used to assess the risks associated with the influence of low and high temperatures on the objects of the electric grid complex.

Authors: Salakhitdinov A N , Mirzokulov Kh B 
Published: October 2020

Abstract
In this paper, we consider a method for creating left-sided metamaterials. We select a method for creating metamaterials from a system with distributed parameters that are non-resonant structures. The equation of a discrete transmission line is solved taking into account the conditions for creating a metamaterial. The resulting solution in the form of effective permittivity shows that such a medium really has a double negative value of both the dielectric and magnetic permittivity. A generalized scheme of a universal method for searching for creating metamaterials is considered.

Abstract
Abstract Taking into account the processes carried out during electrodeposition by rubbing, high-speed copper electrolytes have been developed: low-acid and nitrate sulfate. There are proposed modes for anode-tools with area of 1 cm2, 3.75 cm2 and 4.43 dm2, allowing for application of matte, semi-slush and shiny copper coatings with maximum speed up to 16 µm/min. A procedure has been created for calculating the permissible cathode current density and the required rate of electrolyte supply by dipping and jet methods. The effect of the area of anodes - tools on the maximum permissible cathode current density is determined. The effect of cathodic current density in high-speed copper plating electrolytes on current output and the rate of copper coating application has been established.

Published: October 2020

Abstract
During the Fourth Industrial Revolution, the enterprises which have begun, in due time, to introduce modern approaches to the manufacture organization, including digital technologies, obtain an essential advantage over the competitors. One of the stages of planning the changes is assessing the enterprise informatization level. Evaluating the enterprise informatization level is required for appropriate and effective choosing digital transformation technologies and approaches during the enterprise digitalization. The given assessment represents a multi-criterion problem, demanding the development of the mathematical apparatus and the principles of its use as well. The developed procedure of evaluating the level of the industrial enterprise informatization in digital economy conditions includes the procedure of organizing the assessment of the industrial enterprise informatization level and also the mathematical model of conducting an expert estimation of criteria (indicators) of the organization digitalization. The procedure of assessing the informatization level is performed by the multiplier convolution of criteria. The weights of criteria are defined by the modified T.L. Saaty’s analytic hierarchy process. Also evaluating the weights of each expert’s individual estimation and defining the error of their assessment is conducted. The approach to the proved formation of the enterprise informatization levels is developed. The given technique allows to evaluate the informatization level in some areas and to allocate those which demand the development, to forecast occurring risky situations while introducing information technologies at the industrial enterprise.
The roles of top management in digital transformation
Authors: Artemenko Evgenii 
Published: October 2020

Abstract
Digital transformation denotes the final stage of coverage with digital technologies – from digital competence through digital consumption to digital transformation. Digital economics is based on deep integration of business and IT strategies. Digital transformation is a change in business processes based on data analytics. Not external resources, as it was believed earlier, become, however, the main source of these data, but a company’s internal processes. Apart from the technologies, the key factor of a successful digital enterprise is people. It is human capital that acts as the main resource when forming a business model based on data. Conventional IT models can no longer meet the growing digital necessities of business. Big data analytics departs from IT divisions and ceases to be a prerogative of CIO. The key objective of Chief Digital Officer (CDO) is corporate restructuring, formation of the vision and comprehensive activity plan for transformation of business processes, products, and services into a digital format. Digital technologies and artificial intelligence are not a cure-all problems that are present in the market and in a specific company. Digitalization is not a substitution of real business processes, but is additional to them.

Published: October 2020

Abstract
The level of civil activity and participation of local communities in solving local problems is an important pre-requisite for spatial development. The setting up of local communities, to a large extent, is the outcome of self-determination, the result of the actions of social actors, aimed at value-oriented and active involvement of citizens in local self-administration. Forming the local identity, ensuring the activation of the civil position, is one of the major objectives of municipal authorities. In St. Petersburg, where the local identity of the population is quite vague, and the municipal authorities, in fact, are dependent on the city’s administration, which is preconditioned by the status of the city of the federal significance, the role the municipal authorities play in solving problems of the city’s development must be reconsidered.
At the height of the fourth industrial revolution, information technology is expanding the context and motivation for participating in the civil life, increasing unprecedentedly the level of public discourse and ensuring an interactive network environment for communications between the municipal authorities and local communities.
In the research study, we evaluated the quality of communications between the municipal authorities of St. Petersburg and local communities through official websites and social media pages of intra-city municipalities of St. Petersburg. The research was conducted using the methods of content analysis, communicative-discourse and composite-graphical analysis, and the expert evaluation method. It was concluded that the existing resources are hardly suitable for solving the problems of intensifying civil participation of local communities and some guidelines were developed to detect the target audiences and expand the range of tools used for interactive communications.

Published: October 2020

Abstract
The purpose of the study is to develop a method for assessing the level of digital infrastructure development for doing business in a region and a comparative analysis on the example of the two largest urban agglomerations of the Russian Federation-Moscow and St. Petersburg. The relevance of the research topic is confirmed, on the one hand, by the special role of the Moscow and St. Petersburg in the Russian economy, on the other hand, by the current processes of digitalization going on in the Russian economy. The authors propose a refined concept of “digital infrastructure of the region”, and justify the choice of indicators characterizing its level. The article presents the integral indicator for assessing the level of development of the region’s digital infrastructure, based on separate indicators of two types, characterizing, on the one hand, the material basis and on the another hand, the access to digital infrastructure. The study used a formula for calculation of the integral indicator. The presented formula is the convolution of the indicators of two types taking into account the relative significance of every indicator. The comparative analysis has been carried out, and recommendations have been developed for increasing the level of digital infrastructure development in the largest urban agglomerations of the Russian Federation-Moscow and St. Petersburg.
