The author has developed lightweight polymer silicate shungizite concrete (LPSC) for external walls of buildings with acidic humid gas environments. Exterior wall structures made of this material do not need to be protected by paint and varnish coatings. The properties of LPSC were investigated. The research results showed that the proposed material in its physical and mechanical properties meets the requirements for the material of outer walls. The material has been found to be highly corrosion resistant. Previously, the author presented the results of research of thermal conductivity of LPSC for exterior walls in laboratory conditions. The results of study of temperature and humidity conditions of the wall fragment of the proposed material in natural conditions are given in this article. The studies carried out confirmed the possibility of using the material proposed by the author for the outer walls of buildings with acidic humid-gas production environments.
Stability of rectangular cantilever plates with high elasticity
Authors: Sukhoterin Mikhail , Baryshnikov Sergey , Knysh Tatiana , Rasputina Elena
Published: March 2021

The problem of cantilever plate stability has been little studied due to the difficulty of solving the corresponding boundary problem. The known approximate solutions mainly concern only the first critical load. In this paper, stability of an elastic rectangular cantilever plate under the action of uniform pressure applied to its edge opposite to the clamped edge is investigated. Under such conditions, thin canopies of buildings made of new materials can be found at sharp gusts of wind in longitudinal direction. At present, cantilever nanoplates are widely used as key components of sensors to create nanoscale transistors where they are exposed to magnetic fields in the plate plane. The aim of the study is to obtain the critical force spectrum and corresponding forms of supercritical equilibrium. The deflection function is selected as a sum of two hyperbolic trigonometric series with adding special compensating summands to the main symmetric solution for the free terms of the decomposition of the functions in the Fourier series by cosines. The fulfillment of all conditions of the boundary problem leads to an infinite homogeneous system of linear algebraic equations with regard to unknown series coefficients. The task of the study is to create a numerical algorithm that allows finding eigenvalues of the resolving system with high accuracy. The search for critical loads (eigenvalues) giving a nontrivial solution of this system is carried out by brute force search of compressive load value in combination with the method of sequential approximations. For the plates with different side ratios, the spectrum of the first three critical loads is obtained, at which new forms of equilibrium emerge. An antisymmetric solution is obtained and studied. 3D images of the corresponding forms are presented.

Authors: Zhukov Vladimir , Melnik Olesya
Published: March 2021

The paper is devoted to the study of the regularities of changes in the quality of working fluids circulating through the systems of internal combustion piston engines. During the research, the parameters of fluids that characterize its operational properties, as well as external effects that can lead to changes in the properties of the fluid, were determined. It is shown that the deterioration of the quality of engine oil and coolant of piston engines during operation is caused by the destruction of additives that are part of the fluid and provide their required properties. A laboratory installation has been developed and created that allows simulating thermal and mechanical effects on working fluids similar to those acting during circulation through engine systems. The graphical dependencies obtained as a result of the experiment are presented. Mathematical processing of the experimental data allowed obtaining regression dependencies that correctly describe the processes of changes in time of the most important characteristics of working fluids under the action of cyclic thermal and mechanical effects. The described method can be used to study the influence of operational factors on the properties of various working fluids of internal combustion piston engines.

Published: March 2021

In this article, in the context of home ecology, authors rise the problem of the interpretation of such concepts as «reequipment» and «redevelopment» of residential premises. Which are found in the texts of the Housing Code of the Russian Federation and the Decree of the State Building N170 of 27 September 2003. The authors propose that, along with the well-known components of the ecology of the dwelling, positive changes in the design of the space planning solutions should be considered as one of the criteria for improving the evaluation. In practice, participants in the projects while improving the environment in the homes, face the proliferation of these terms, which are misleading and require further specifications. The article contains the results of real housing redevelopment projects implemented in 2019-2020 in the Kalininsky district of Saint-Petersburg. In addition, the main preferences of the owners of the apartment buildings were taken into consideration. Until recently all of these activities were carried out by the owner, but at the time of the research all works were carried out by licensed specialists. It is suggested that such projects will continue to evolve, however, this process will depend on the introduction of new environmentally friendly building materials and technologies. Moreover, when household appliances will take a bigger share on the consumer market, there will be the improvement of the quality of the indoor environment and it will diversify the capabilities of the owners.

Twilight of architecture
Authors: Tkachev Valentin
Published: March 2021

Architecture is a subject indicator of the adaptation of any organized system to the circumstances of the environment, even if it transforms this environment itself. Adaptation to the environment was the main goal of man in the early stages of civilization. Subsequently, the roles have changed. Society is now actively attacking and changing nature, solving two main tasks - creating a comfortable living environment and ensuring its social status by means of composition and artistic expression. The decoupling of these tasks led to the ramification of the work on the environment into trivial and expositional architecture; this is especially noticeable today. In search of the expressiveness of the image, artistic and tectonic sources have already been exhausted, and architecture is now plot-immanent to itself, ignoring the usual external stimuli of creative ideas. The first violation of traditions made the freedom of form-making legitimate, opened the doors to teratogenesis (implantation of ugliness), and architecture finally turned into an object of plastic experiments that frighten the townspeople with strange structures of mysterious functional purpose. This, of course, is about an expositional architecture, the expressiveness of which sometimes reaches a state that is far from common sense, insulting the existing buildings with a super-scale and absurdity of forms. The architects played too much, not suspecting that the figurative eccentricity of their works testifies not to the triumph of a new aesthetics, but to the twilight of the general culture revealed by architecture.

Authors: Kireeva Natalia , Zavyalov Dmitry , Saginova Olga , Zavyalova Nadezhda , Saginov Yuri
Published: March 2021

The use of car sharing instead of owning a car minimises the negative impact of logistics activities on the urban environment. This research aims to show that sustainable development of densely populated cities is accompanied by an increase in Internet users’ interest in sharing services. The research of Internet users’ interest in car sharing services was based on Google Trends data on search queries originating from Russia, the United States and Canada over the past five years. In the course of this work, the hypothesis was confirmed that high user interest in car sharing is mainly observed in urban agglomerations with high population numbers and density, where the positive effects of car sharing are most noticeable. The paper emphasises the need to encourage the creation of new services in urban logistics, which will contribute to sustainable development and increase the competitiveness of cities. It also confirms the hypothesis that the growing interest of Internet users in the new service is accompanied by an increase in the market volume. User interest in established car sharing markets is at a stable level, except for the occurrence of significant events (e.g., the emergence of a new major player in the market) that stimulate an increase in interest.

The main prerequisites for the development of wooden housing construction in Russia are given, which determined the goal of this study - to develop a mathematical model of heat and mass transfer (moisture transfer) in glued timber for rational design of enclosing structures. Lamellas can be classified as a capillary ‒ porous body. leaning on theory of academician A.V. Lykov, the formulation of the problem of heat and mass transfer in a multilayer glued laminated timber is presented a system of equations describing non-stationary heat, mass and pressure transfer under real possible operating conditions of enclosing structures is considered. An analytical method is proposed for calculating both individual lamellas and the entire multilayer glued beam. The proposed technique allows the method of solving the inverse problem to directly calculate the resistance value of the entire bar from the unsteady temperature field. The system of equations describing the process is nonlinear and analytically insoluble. To solve the problem, a combined method for solving boundary value problems of heat transfer was used, which is based on a combination of elements of analytical and numerical solutions. A feature of the problem under consideration is that the middle lamella has heat-conducting inclusions in the form of a bough. Method is that the entire heat transfer process is divided into a number of small time intervals. Within each interval, we assume that the temperature is constant at the interface between layers and a constant heat flux through the contacting surfaces, i.e. perfect thermal contact.

Bioeconomy is based on advances in microbiology that can be used in various processes associated with the use of biological resources; it is changing consumer preferences by bringing a new understanding of resource constraints. Despite the fact that a great contribution has already been made to the science of bioeconomy, much in it still refers to promising scientific developments in such areas as biology, biomedicine, engineering, artificial intelligence, technology, chemistry, etc. This paper provides an overview of the current strategies of different countries in the development and implementation of bioeconomy. Purpose of the work: systematization of target indicators and identification of the most significant among them for different economies. The results of the study point to the need for an in-depth analysis of the challenges and opportunities the world faces on the road to bioeconomy. In addition, it is shown the need to develop common global criteria for assessing the bioeconomic development.
Strategic management of the development of an innovative energy efficient cluster
Authors: Palamarchuk Alexey
Published: March 2021

One of the most important areas of innovative development of economic systems of Russian regions is the formation of clusters. The global changes occurring in the innovation economy within the framework of the Fourth Industrial Revolution predetermine the emergence of new requirements for the created clusters, including the systemic digitalization of enterprises and organizations that are part of them, as well as increasing their energy efficiency. Taking into account these requirements, the author proposes a new type of cluster structure - an innovative energy efficient cluster. The author develops the structure of the program for the strategic development of an innovative energy efficient cluster, in which seven strategies are identified, reflecting the key directions of its development. As part of the final section of the program, the author develops a classification of target indicators of the effectiveness of implementation of the strategic development program.

The article examines the tendencies and prospects for constructing adaptive mechanisms for the functioning of active systems, taking into account the influence of the tendencies of the fourth industrial revolution, called “Industry 4.0”, on the quality management system of enterprises. The main components of “Industry 4.0” is the global digitalization of all enterprise processes, including management processes, which makes the process of creating learning mechanisms of functioning (MFF) of active systems, which are able to improve their functioning over time, considered relevant. The described construction of the GFM is based on the use of learning processes carried out using probabilistic iterative (recurrent) algorithms. These algorithms make it possible, as a result of processing current information, to make up for the lack of a priori data and, ultimately, to achieve the best, from a certain point of view, performance indicators.
New approaches to multiciterial evaluation of alternatives in decision-making

This work is devoted to the development of mathematical models that make it possible to generalize the data obtained in the multicriteria assessment of alternatives when making decisions under certainty conditions. A typical problem in multi-criteria assessment is the integration of particular criteria-based assessments of alternatives into some integral indicator reflecting the degree of attractiveness of alternatives. Traditionally, for these purposes, an additive method was used, which consists in the fact that the final assessment of the alternative is the sum of the assessments by the criteria, possibly multiplied by the weights of the criteria. However, this approach has a number of significant disadvantages, which include the following. When evaluating alternatives, such an indicator of their validity as feasibility is not taken into account, which leads to a distortion of the result due to too simple or difficult criteria. Evaluations of alternatives by qualitative and attributive criteria are subjective, since they are obtained by expert methods, which introduces subjectivity into the integral assessment of the alternative. The integral assessment of an alternative depends on the composition and number of assessed alternatives and on the set of assessment criteria. To eliminate the second drawback, a model for evaluating qualitative alternatives is proposed, which implies the introduction of a certain numerical indicator for a qualitative criterion, which for each alternative have a different meaning, while the attractiveness of the alternative depends on the indicator value. The set of alternatives in relation to the indicator is considered fuzzy, with the belonging function depending on the indicator.

Job performance behaviour of employee is a critical driver of organization performance. Airline operations employees namely, pilots, cabin attendants and ground service agents can increase organizational effectiveness. This research analysed the effect of individual characteristics, organization behaviour, learning and development and compensation on operations employees performance. The purposes of this study were (1) to identify factors affecting job performance of airline operations employees in the context of Thailand, (2) to evaluate success factor categories with employee job performance, (3) to explore significant difference between ranking results from two certain groups of respondents. A random sample of 400 respondents divided into two groups, group one- 200 experienced employees (60 pilots, 70 flight attendants and 70 ground service agents) from five airlines in Thailand, group two- 200 HR strategic experts and HR university lecturers completed an online survey. Research concluded that rank order views from both groups were not much different. It showed that job performance is highly associated with organization behaviour, which is motivated by organization culture, organization structure, workplace ambience and leadership and teamwork process. HR experts rated the importance of learning and development in the second order while employees rated the importance of compensation in the second place and perceived learning and development as the least important.

The high use of web systems in learning implies that e-learning is becoming a common successful learning method in wider academic contexts. In order to enhance and support schooling and literacy, e-learning includes leveraging information and communication technology (ICT). The purpose of the analysis was to determine the correlation between e-learning and the academic achievement of students in higher learning. A set of 150 author’s observational studies, carried in Russian educational institutions (both in the period before and during the COVID-19pandemic), was used to measure findings using Cohen’s formula focused on a rigorous sampling method. The findings of the equation (= 0.712) reveal that ICT has a major statistically favourable effect on the academic success of students in elearning. The results suggest that ICT has a substantial positive effect on the total success of students in universities.
