Published: November 2020

Abstract
This paper studies the low frequency seismic phenomena on the overheating boiling process and the cavitation state of the coolant in a small volume of system. This experiment is basically the imitation of the situation in a nuclear reactor core where distilled water was used as coolant during the experiment. Temperature of the coolant was recorded during the normal state and the time of implementing external low frequency. The stretched state of the liquid due to overheating and the cavitation destruction process were investigated.
Safety provision during development of the underground mine in water-bearing karsted rock mass
Authors: Melnik V V , Zamyatin A L 
Published: November 2020

Abstract
The present article describes issues of up-to-date methods and approaches to ensure safety during development of the underground mine in complex engineering-geological and hydrogeological environments. As a priority to ensure safety while constructing mine workings on the karsted territory is the decrease of water content of the rock massif due to construction of spot water intakes above ground. The efficiency of dewatering depends on quantity and capacity of dewatering wells, The same parameters influence on prime cost, so that in the suggested approach the maximum productivity is reached by selecting drilling sites by means of ground geophysics together with study of geological and hydrogeological conditions. In the presented paper, there is an example of successful drainage of karsted layer by constructing water intake consisting of two dewatering wells, which enabled to start developing the ore shoot, which was on suspension due to the complex environment.

Authors: Gerber Yu A , Sebeshev V G 
Published: November 2020

Abstract
The problem of analysis linearly deformable systems with a finite number of single-mass dynamic vibration dampers (DVD), used as regulators of the stress-strain state (SSS) with different variants of the harmonic load (by location and type) was considered. Equations of state of the system with dampers have been obtained and a method has been proposed to choice a set of parameters (masses and stiffness) for each of the DVD, taking into account the properties of the system, loads, and parameters of other DVD and the specified requirements of regulation. The developed design apparatus has been used for solving a model problem of a dynamic SSS regulation in a rod system with several dampers and for estimation of its reliability with polycriterial serviceability requirements. The quantitative results of calculations are presented. The comparative analysis of the reliability have been performed for unprotected systems and systems with DVD. The possibility of determining the rational location and parameters of DVD under harmonic non-point loading with the target reliability of the structure is shown.

The Role of the Internet of Things (IoT) in Energy Management of a Smart City
Authors: Maltseva I , Tkachuk K 
Published: November 2020

Abstract
The 2030 climate & energy framework contains three key targets for Europe: to cut greenhouse gas (GHG) emissions and increase the share of renewable energy (RE) sources and promote energy efficiency. These tasks are relevant for Russia as well. As one of the frontrunners, Germany has raised its RE share target to 65% by 2030. At the same time, global energy needs are expected to increase by 30% by 2040. In this context, energy systems should not only be planned for the current supply but also be designed for a substantial increase in energy demand. To achieve these goals and avoid an energy crisis, the general idea is to shift from centralized to decentralized energy systems. Furthermore, energy sectors are currently integrated with Information and Communication Technology (ICT) solutions, especially the Internet of Things (IoT), for efficient and sustainable energy management. The article analyses the role of IoT technology in existing and future energy systems according to three scales: flat, building and city.

Implementation of Zero Liquid Discharge Systems in Russian Industry
Authors: Aksenov V , Tsarev N , Maksimova E 
Published: November 2020

Abstract
The article focuses on the implementation of zero liquid discharge (ZLD) systems precluding the pollutant release to the environment at metallurgical, machine-building and metalworking enterprises. The need to change over to such systems is due to two main factors: 1. Significant savings in fresh water used in production; 2. A decrease in the number of all kinds of pollutants reaching the environment with various discharges (purified, insufficiently purified and completely untreated). The main feature of ZLD systems at industrial enterprises is the presence of tailing management facilities, e. g. concentrated wastewater treatment facilities; industrial wastewater sludge treatment facilities; non-recyclable oily wastewater and sludge incineration facilities; reclaimed (recycled) industrial wastewater treatment facilities etc. The development stages of ZLD systems in Russia are presented. In 1973, for the first time in the world’s practice, in the Verkh-Isetsky Metallurgical Plant in the city of Sverdlovsk (now Yekaterinburg), the ZLD developed by Prof. V. I. Aksenov and his colleagues was launched and has successfully operated in the cold rolled transformer steel workshop. As an example of wastewater treatment facility as part of a ZLD system, some technical installation solutions are described in order to treat chemically contaminated acid ferrous-containing wastewater generated in pickling carbon steel. The focus is on the feasibility of implementing local ZLD systems instead of central ZLD systems. The advantages of such local systems are: possible regenerating exhausted process solutions at the place of their formation, obtaining demineralized water, the local treatment of chemically polluted wastewater, lower investment and operating costs.
Ordination Architecture Analysis: Calculation of Proportionality of Order Form Elements
Authors: Dolgov A V 
Published: November 2020

Abstract
Architectural ordination is part of the theory of architecture dating back to antiquity but in many ways distorted today. The generalization of approaches to it gives two directions of research, namely, abstract (the search for universal laws of proportionality) and empirically-specific (the analysis of the proportions of an individual object). Adhering to the second approach, the author develops his own version of ordination analysis based on major-minor ratios. The calculations are confirmed by the results of measurements of buildings of different epochs and tested in the design practice presented in the article. Objects created on the basis of the theory of ordination can belong to different styles, but, undoubtedly, harmonize the human condition and the urban environment.

Abstract
The problems in processing the acid ferrous-containing rinsing water and spent pickling solutions are considered. The first-ever in metallurgy zero liquid discharge (ZLD) industrial wastewater treatment systems of a transformer cold rolling plant at the Verkh-Isetsky steelworks in Sverdlovsk (now — LLC VIZ Steel is a part of Novolipetsk Steel Group of Companies) is described. The experience of the VIZ Steel, particularly in relation to industrial wastewater treatment and sludge processing, is useful for designing ZLD industrial wastewater treatment systems of metallurgical, machine-building and metalworking enterprises. The recommendations for organizing the ZLD industrial wastewater treatment systems in the pickling plants with the repeated use of the treated rinsing water and processing the spent pickling solutions and the sludges are presented. For practical calculations of clarifiers the empirical formulas are offered. Process flow diagram of acid ferrous-containing rinsing water treatment is suggested. Acid ferrous-containing rinsing water treatment includes the following processes: rinsing water neutralization to pH 9-10,5 by 5 % calcium hydroxide and partial ferrous oxidation by air; addition of anionic flocculant and active gypsum priming to the neutralized rinsing water; settling of rinsing water conditioned by reagents in clarifiers; treatment of clarified water on deep bed sand filters; reclaimed water treatment.

BIM within current building facilities and infrastructure
Authors: Nyvlt V 
Published: November 2020

Abstract
One of the main reasons for introducing BIM into existing buildings is cost savings in the construction management and maintenance phase (operating phase). Operational phases have the biggest impact on the total life cycle costs. The introduction of BIM and the creation of a building information model, albeit at a higher price, will be counterbalanced several times by a more efficient way of managing the building during its life cycle, the possibility of creating a healthier indoor environment for building users and better access to necessary information, for example in the case of changes to completed buildings. The BIM model is a digital equivalent of a real construction – real digital twin. It contains geometric data in the form of a 3D model and non-geometry data, including construction management and support documents. The BIM model allows access to building usage information. The information obtained is more accurate. It keeps building element information up to date, enabling more informed decisions. It supports comparison of different solutions and their energy needs. Renovation can be done more efficiently. Construction information is up-to-date, so we can use the time needed to process different solutions instead of finding the necessary information about the construction.

The area of its rational use is outlined, where, using alternative design of known and new solutions, a quantitative assessment of the resources of their carrying capacity is given.
Effect of Limestone Filler Dosage and Granulometry on the 3D printable Mixture Rheology
Authors: Slavcheva G , Artamonova O , Babenko D , Ibryaeva A 
Published: November 2020

Abstract
The article presents the experimental results concerning the influence of the concentration and a particle size distribution of limestone filler on the rheological behaviour of cement pastes as matrixes of 3D printable concrete. The squeezing test is used in this paper as a rheological behaviour identification tool of cement-based materials in order to evaluate the extrudability and buildability. It has been established that introduction of filler as a factor changing the properties of solid phase in the system “cement + water” is an effective method for plasticity regulation and increasing the 3D printable cement-based materials resistance to load during the printing. Structural stability of cement paste can be improved by 2 times by introduction of filler with efficient ranging of a particle size in dosage of 20 – 40 % by weight of cement. Cement paste with limestone filler having a particle size distribution ranging from’ to 75 μm is characterized by the optimal plasticity, structural strength and deformability under the load. Using limestone filler with equal particle size impairs these characteristics of cement paste.

Authors: Yakubovskiy Y E , Kolosov V I , Donkova I A 
Published: November 2020

Abstract
The paper presents a calculation of the stress-strain state of composite plates. The mathematical model obtained by the authors earlier has been applied. In contrast to the previous results, the viscous-elastic properties of the material are taken into account in describing the behavior of the intermediate layer. The developed creep kernel of the layer material contains the expression that serves to describe the properties of the aging material. The compliance of the proposed formulas with actual processes has been proved by comparison with experimental data. In the numerical implementation decomposition of the expressions under integral sign into the Maclaurin series has been used. Based on the experimental data, the parameters of creep kernels have been determined. The parameters have been determined by minimizing the calculated data standard deviation from the experimental ones. The algorithm based on the random search method has been implemented. The results of the calculation according to the developed mathematical model have been given. The analysis of time variation in the stress-strain state of the joints between the layers of the composite structure has also been given.
