Authors: Repinskiy O D 
Published: November 2020

Abstract
Creation of an effective system for using information and telecommunication technologies (ICT) is one of the main factors to improve Russia’s competitiveness in the global market. The country’s leadership has developed a set of documents on strategic development in the field of information and telecommunication technologies (ITC) inter alia the "Strategy for development of information society of the Russian Federation for 2017-2030" dated 05/09/2017 No. 203. Russia currently is far from leading positions in the field of information and telecommunication technologies (ITC) in the world market [1]. To change the situation for the better, it is necessary to determine the factors impeded ITC development and take steps aimed to reduce the impact of such factors. Information and telecommunication technologies are developing according to certain market rules which have been formed for more than a decade in parallel with the development of society. The emergence of innovative products and services in the segment has formed modern society in developed countries [2]. First of all, the Internet creation has led to emergence of the new products: sites, portals, online stores, online games, social networks [3]. Second, many companies involved to that kind of activity were established: in the face of intense competition as a result of mergers, acquisitions, splits on the securities, market large players with rapidly growing capitalization appeared - Google, Microsoft Corporation, Facebook, AliExpress. Information and telecommunication technologies are a new stage in the development of modern civilization; its latest trend is based on the creation and using of innovative products in all aspects of its life [4]. Russia has no alternative. In order to improve competitiveness in the world market, it is necessary to efficiently and quickly produce and put into practice various information and telecommunication technologies.

Authors: Shumskaya O 
Published: November 2020

Abstract
The research of informational content of features in the spatial and the frequency domains at steganalysis of the compressed JPEG-images is presented. Modern steganalysis methods, based on which the feature set has been created, are considered. As a method of informative features selection has been applied the greedy algorithm with an exception which has allowed reducing number of features in the set from 43 to 26. The experiments have shown that steganalysis on the basis of informative features allows increasing the accuracy of correct classification of initial images to 94%, of images with attachments by the PM1 and the Jsteg methods by 25 and 18 percent respectively. The issue of steganalysis of images with artificially created distortions is mentioned. The experiments showed that steganalysis based on informative features allow classifying correctly such images with the accuracy 96%.

Published: November 2020

Abstract
The authors investigate whether it is possible to improve the models of the electric drives of vibration sources using Matrix Laboratory Simulink. The test subject is the simulation model of the electric drive of a borehole vibration exciter based on a linear double-acting electromagnetic machine. The simulation model consists of the power and control subsystem of the electric drive. This model allows the wide-range parametric analysis of processes in the electric drive by the computer modelling methods. The oscillograms of voltages and currents are obtained in the case of the electric drive control by the piston position for real-life and ideal sources of power supply. The oscillograms are compared, and the calculation error is estimated.

Abstract
The application bottleneck is the database architecture. The applications developed more than 10 years ago suffer from low database performance. The databases in companies strongly enlarged during this time and began to work quite slowly. The article describes how the inclusion of master-master replication will optimize the backend operation to some extent without resorting to major changes. It will allow even distribution of requests across several (in this case, two) servers, regardless of the requested method.

Published: November 2020

Abstract
The paper examines the design and modeling of the robotic surgical system that is used for transurethral operations with resectoscopes. The proposed system consists of a robot-manipulator and a control system for a surgeon. A design feature of the robot-manipulator is the presence of free rotation units that ensure the mobility of the instrument together with the holder unit. This design eliminates a patient injury when one is displaced relative to the initial position. Another important feature of the proposed surgical robotic system is the ability to use an existing surgical instrument (resectoscope). The article describes the design, as well as the results of the modeling of the robot in the V-rep system. The parameters of the forces and torques of the executive system of the robot are obtained by simulation.
Methods of geomonitoring of technogenic objects to determine fast-flowing deformation processes using robotics
Authors: Knoll I A , Sharapov AA , Solovieva TA 
Published: November 2020

Abstract
A method of geomonitoring of technogenic objects to determine fast-flowing deformation processes using robotics based on the theory of multi-agent systems is proposed. The methodology is based on the conceptual geomonitoring scheme of an anthropogenic object by a group of "georobots" and a hardware and software complex represented by intelligent "georobots" that are functionally interacting with each other. The method developed by the authors makes it possible to exclude the direct presence of a person from the process of collecting data on the spatio-temporal state of an anthropogenic object. This method helps to promptly provide information on the state of an anthropogenic object in dangerous fast-flowing processes, which contributes to the timely determination of a practical managerial function to eliminate the accident.

Abstract
Video cameras are widely used in underwater robotics to construct 3D coordinates of the workspace. However, the accuracy evaluating that takes into account the properties of the underwater environment, and technical implementation in uncontrolled conditions is still a difficult task. This assessment is especially important for robots that are focused on performing operations with items. In this paper, we propose a novel technique for accuracy analysis and demonstrate its possibilities on real data. It is based on a statistical approach that allows estimating the influence of all sources of perturbations using only experimental data obtained in an underwater environment.

Modeling of balancing transformers to determine the effectiveness of their application
Authors: Akhmetshin A R , Marin GE , Mendeleev D I 
Published: November 2020

Abstract
One of the urgent problems is providing consumers of distribution electric networks with high-quality electricity. The most important indicators of the quality of electricity are the level and asymmetry of voltage, the deviation of which from the normative indicators leads to disruption of operation and a decrease in the service life of electrical equipment. If the standard indicators of electricity are not met, the consumer has the right to demand compensation from the electricity supply companies. For balance the voltage on the 0.4 kV side of the step-down substations, it is promising to use transformers with a balancing winding both in new construction and in their reconstruction. The problem of determining the effect of the use of transformers with a balancing winding is that the manufacturer does not provide the necessary parameters for them to ensure the calculation of the phase voltage level when connecting an asymmetric load. Also in existing software products, such as, for example, Matlab/Simulink, there are no ready-made mathematical models of the transformers under consideration. As a result, it is impossible to reliably assess the benefits of replacing conventional transformers with a balancing winding, when the task of a feasibility study for the reconstruction of a substation arises in order to ensure standard indicators of the quality of electricity and reduce electricity losses.

Abstract
The influence of the geometric profile of the air gap of the magnetic circuit on the power and energy characteristics of an electromagnetic engine is considered. The research is relevant because of the need to improve the methods for the optimal construction of electromagnetic engines to solve the complex problem of increasing the efficiency of vibration systems with linear displacements of executive parts. The object of research is the construction of an electromagnetic motor created on the basis of an electromagnet with a flat attracting armature. The research was performed using finite element magnetic field simulation using the program Finite Element Method Magnetics (FEMM). Options for building models are considered. The differences in the efficiency of using the compared structures of electromagnetic motors of the same size and weight from the conditions of their economy are shown. The magnitude of the electromagnetic force and mechanical work are used as evaluation criteria.

On the possibility of operational management of reservoir pressure in a multilayer reservoir exploited by dual completion and injection method based on recording current gas factor of products extracted from each reservoir
Authors: Davydova O V 
Published: November 2020

Abstract
The paper discusses the problem of operating complex and expensive telemetering equipment designed to monitor and control a multilayer field operation using the dual completion and injection method. The author offers an alternative to the applied wireless and wired data transmission (as the first type does not have the required range and the second does not have the required reliability) technology. It is a new method for monitoring and controlling reservoir pressure in real time based on recording the current gas factor of the products extracted from each layer using dual completion method and ensuring its relative stability due to the operational management of their reservoir pressure through the dual injection system. At the same time, it is proposed to use commercially available automated group measure unit equipped with corresponding sensors as the means of measuring gas/oil ratio. Testing the method of reservoir pressure management proposed by the author for the two-layer reservoir of the Tedinskoye field of Lukoil-Severneftegaz confirmed its effectiveness, which served as the basis for the development of an appropriate methodological guide and filing of a patent.

Abstract
Lean manufacturing classical format must be re-organized with the Industry 4.0 requirements. The base innovation is the production client-centricity to justify the appearance of synchronicity mechanisms of the new cyber-machine (CM). Several items product bunches may limit the CM re-arrangement time under the tide production conditions. The CM remote operative re-arrangement is a non-alternative way to reduce the production expenses after some machines non-engagement. We proposed a U-way scheme of CM with client service integration. Lean manufacturing technologies are a service factory base. The client service provides the fixed attributes settings of the item being manufactured using CM to unite client service and CM resources means to create a general industrial environment tools repository, which functions with lean manufacturing principles.

Published: November 2020

Abstract
The relevance of the work is due to the search for opportunities and tools for obtaining analytical information to assess the quality of life of the population of the digital city. The heterogeneity and constant complication of human activity in modern cities, as well as the unique economic, cultural and managerial specifics of various countries and cities determine complexity of the problem under consideration. The transformation of urban life and citizens’ activities entails the need for a qualitatively new construction of the relevant organizational, managerial, information and communication structures, which must fulfill their functions with sufficient efficiency, minimal resources, and at the same time, have the flexibility and adapt to fast-paced development of cities. The development and evaluation of indicators of the quality of life of the population in the “digital city” seems to be a necessary component of the effective social and technological progress of the Russian society.
