Green Buildings - sustainable development strategy
Authors: Tabunshchikov Yury , Brodach Marianna , Shilkin Nikolay
Published: May 2020

Green construction is one of the most promising directions for development not only in the construction complex, but also in the social environment. Green buildings, as human environment, are attractive for investors, designers, utility equipment manufacturers and housing owners. Requirements for green buildings are sufficiently high and cannot be met by the traditional design principles based mainly on typical solutions. As a result we need to arm designers, builders and operators with new creative knowledge. In essence certification of a facility as a green building initiates a creative search for architects and engineers of such technical solutions that minimize negative and optimize positive influence of energy, environmental and technological factors that define the building as human environment. In this work it is difficult to separate the creativity of architect and engineer: we have to consider their joint work during the entire design process and only such union can bring success in achievement of the set goal.
Creating a neural network system for forecasting and managing agricultural production using autocorrelation functions of time series
Authors: Rogachev Aleksey , Melikhova Elena
Published: May 2020

The article considers the features of creating an artificial neural network (ANN) for modelling and forecasting the dynamics of long-term time series (TS) levels of grain yield in arid conditions on the example of the Lower Volga region of the Russian Federation. In order to increase the validity of the choice of architecture and macroparameters developed by ANN, statistical characteristics of the simulated TS were analysed. The autocorrelation function of distribution of levels of long-term series of grain yields is constructed. It is proposed to take into account the characteristics of time lags of autocorrelation functions when selecting ins macroparameters for predicting BP yield. On the basis of preliminary statistical analysis, "peaks" corresponding to the time lags of the autocorrelation function, whose values are determined for different groups of grain crops, are identified. The obtained values are recommended to be taken into account when selecting the value of the time window parameter when constructing neural network models of productivity. This is the basis of the proposed information technology for building ins for predicting crop yields. The results of neural network modelling and yield forecasting can be successfully used for managing agricultural production, including in the arid conditions of the Lower Volga region of the Russian Federation.

Authors: Nikitin Evgenii , Pavkin Dmitrii
Published: May 2020

The goal of the research is a mathematical modeling of the motion process of a wheeled robot along a given trajectory with the turn drill. Matlab software with the Simulink option package was used as the environment for artificial modeling of the motion process. In order to control the movement of a wheeled robot using the computational and graphic methods, a kinematic and dynamic model of a wheeled robot was determined. The robot has two independent drive wheels located on the same axis and operating on electric traction. Based on the obtained mathematical correlations, a nomenclature of artificial components was formed in the Matlab (Simulink) environment, which made possible to simulate the process of controlling the robot’s electric drive. A voltage that was twice as different was applied to the electric drive of independent wheels located on the same axis as a reliability check of the mathematical model in the Matlab (Simulink) artificial medium. The artificially simulated motion process of a wheeled robot involved studying the motion process using the “PLOT (X; Y)” function. At the moment of the robot’s movement, the trajectory of the00point, which is the center of robot’s mass, for a set unit of time, was obtained. This allowed confirming the reliability of the developed mathematical model for the control system of a multifunctional robot for animal units.

Authors: Ovchinnikova Natalia , Burdova Daria , Garanova Maria
Published: May 2020

This article covers the problem of rational use of land taking into account the economic and environmental aspects, aiming to eliminate any irrational use of land plots in the future. For this reason, it specifies the parameters characterizing the components of a rational land use concept, namely, its compliance with the intended use, sustainable soil fertility and environmental situation. The achievement of rationalization often contradicts the basic objectives of the concept of territorial development. To avoid such contradictions, the authors disclose the principles of rational land use. As of today, the concept of rational land use covers aspects in various spheres, such as ecology, economics, sociology, and, besides, affects environmental measures. Land resources management refers not only to the use of land resources, when natural and economic conditions and properties of the territory are the most fully taken into account, the fundamental socio-economic interests of the society are ensured, high efficiency of production and other activities is achieved, and the productive and other soil properties are recovered and ensured, but also to the possibility of using land by legitimate land users.

Published: May 2020

The relevance of the research topic is that the improvement of the land and real estate market is one of the most important goals of the development of digital economy of the Russian Federation. In recent years, a number of regulatory documents have been adopted in the field of state cadastral registration and registration of real estate titles. Some elements of state development programs of the Russian Federation in the field of land and real estate management were also introduced. An analysis of the documents shows that the introduction of a three-dimensional spatial description of real estate in the unified state register of real estate is beginning gradually. Its purpose is to eliminate a number of problems associated with state cadastral registration of real estate objects located at different levels (above ground, ground, underground), as well as unique buildings and structures. Despite all the available options for accounting for three-dimensional models of real estate in the unified state register of real estate, in fact, their registration in cadastral works is not performed in Russia. This is caused by the lack of scientific and methodological justification for implementation of cadastral work on three-dimensional modeling of real estate objects, taking into account domestic characteristics.

Authors: Chemagin Andrey
Published: May 2020

The researches were carry out by stationary and mobile hydroacoustic computerized complexes in the floodplain-riverbed complex of the Irtysh River (Western Siberia, Russian Federation). It was established that during the migration period during the spring flood, patterns of distribution of fish in the stream are observe due to the size-taxonomic characteristics of the fish population and the physiological capabilities of the organism of fish. With an increase in the flow velocity characteristic from the near bank part of the river to its midstream, the proportion of cyprinids in the watercourse decreases, and the proportion of fish with body sizes> 15 cm increases. The number of fish smaller at high-speed sections of the river increases with an increase in water temperature, which in turn indicates the increasing physiological capabilities of representatives of Cyprinidae family. Absolute numerical dominance of migratory fish and the largest proportion of cyprinids were observed in the low velocity section of the river, located closer to the shore. The indicator of the proportion of cyprinids have a direct strong correlative relationship with the temperature factor (0.70-0.73, P<0.05).

Published: May 2020

In this research the influence of natural and climatic conditions on the organization of construction production are examined. Our purpose was to identify the nature of the dependence of the duration of construction work on natural and climatic factors. The analysis of normative and technical documentation in terms of accounting for the influence of natural and climatic factors was made. The system of estimation of influence of natural conditions on preparatory, ground, facade, roofing works, and also the appliance of monolithic structures, installation of prefabricated ferroconcrete items, and on works – implementation of internal finishing is offered. It was estimated, that the norms of construction production take into account a certain number of natural and climatic factors affecting the performance of work, but most of these factors have not yet been given in the normative and technical documentation. It is necessary to study this issue more comprehensively and to establish exact dependences on natural and climatic conditions, which will allow to quantify these factors already while calculating. This is necessary to compile more accurate calendar plans and schedules of production of works, as close as possible to real conditions. The study of this issue is one of the most important issues in the design of construction production. With insufficient consideration of these factors, the final actual figures are very different from the projected ones, which also lead to an increase in the cost of construction and installation work and the duration of their implementation. Taking into consideration the influence of natural and climatic factors will allow planning construction production more accurate.

Published: May 2020

The housing market is one of the most important segments of the economy of any country. As part of the study, it is shown that it is not enough to consider the housing market financing system only in the organizational and structural aspect. The application of a structurally functional approach is essential, which will improve the efficiency of market financing. The author determines the need for the formation of auto-regulators that can reduce the need for manual control of the economy of the housing complex and the state, which is especially important in the modern economic system. The study identified such auto-regulators as the inclusion of borrowers in the quality management system and the usefulness of housing finance; organization of interaction of market and state financing based on the principles of public-private partnership; the need for a system of indicators to assess the development of the Russian housing market, improving the information support of financial markets; the formation of an open system for monitoring the status of the housing market financing system.

Authors: Gurtuev Alim , Ivanov Zaur , Sabanchiev Anzor
Published: May 2020

We study the effects of institutional information disclosure on the market equilibrium in a local market with knowledge asymmetry and scarce information. The purpose of our work is the analysis of long-term efficiency of a dedicated institutional mechanism of information disclosure for such a market. The paper presents the game-theoretic model of a local property rights market with an infrastructural institution disclosing non-personalized information in a system with a combination of market elements, administrative and shadow economy. For each object, there is some hidden non-transferrable information essential for assessment. Under such conditions, the influence of subjective biases on the market equilibrium can be described as a Bayesian probability model of adverse selection. In the elaborated model, the equilibrium parameters are theoretically analyzed. It is shown that information asymmetry in the modeled systems leads to an irrational allocation of investment resources. It is shown that the infrastructural institutions disclosing non-personalized information are not only unable to efficiently counteract adverse selection, but facilitate it.

The choice of the optimal option for the production of in the construction of buildings and structures is based on a preliminary generalization and analysis of the most promising options for the implementation of construction and installation from which the most rational optimal in the is selected conditions under consideration. The purpose of the study is to determine the optimal option for production of at the convex cost function. We used the method of the determination of costs on the duration of works, represented by a convex function showing the shorter the duration of the project the more costs are required when it is reduced by the same amount. The key parameters affecting the final result of construction are the duration cost and quality of performed. Consequently, one of the main tasks is to draw up a works schedule with close coordination of the resources necessary for their implementation. To do this we have to solve problems associated with the distribution of limited resources. In this case, the technological interdependence between the works performed, which may be of a different nature, should be taken into account. As the results, new approaches were founded to developing a strategy for the selection of options for construction and installation works in order to ensure contractual deadlines for their implementation and minimize the funds spent on their implementation taking into account the nature of the dependencies between the works performed is an urgent and important problem.

Authors: Manukhina Lyubov , Prykina Larisa
Published: May 2020

When analyzing real estate construction, the following features should be taken into account: when erecting real estate, it is necessary to reflect its essence by nature and types of objects of labor that are in a stationary state (buildings, structures, land and property complexes); instruments of labor and living labor, which, on the contrary, are in constant motion with respect to objects of labor. Consequently, the efficiency of construction processes depends on the correlation of parameters characterizing immovable elements with parameters characterizing movable ones. The harmony (balance) of the results of real estate elements joint functioning should be determined with the help of technical, environmental and economic indicators, which can be measured using a single indicator - energy.

To implement the concept, it is important to be able to manage innovations using the protective, strategic functions of the created innovations that provide technological and informational advantages and block the entry of competitors into the market. Based on the analysis of the group features of innovations, two groups of classifications were developed, depending on the goals of creating innovations and the resources used. The developed model for the development of innovative processes allows enterprises to improve innovative processes for more efficient production and sales of products.

The paper presents the model of obtaining a comprehensive assessment of economic security for a group of enterprises. A comprehensive assessment of enterprise ES is based on the assessment of measures for some components of ES. The work highlights the components: financial, information, personnel, technical and technological, legal and power. Much attention is given to the traditional estimation method and an alternative approach based on the Rasch model for estimating latent variables. A comparison of the estimates of ES obtained by different methods is carried out, and using computational experiments, the adequacy and objectivity of the estimates obtained by the method proposed in the work are established. In addition, it was shown that a model based on the theory of latent variables has the following main advantages over the additive model, which follow from the properties of the Rasch model: comprehensive assessments of enterprise ES are their individual characteristics and are independent of the set of components for which the assessment is carried out; EB scores are measured on a linear dimensionless scale that can be easily converted to any other scale; in addition to comprehensive assessments of the ES of enterprises it is possible to obtain estimates of the ES components obtained for the entire group of enterprises, which are also individual for the components and linear.

Management accounting and management of an agricultural enterprise includes strategic planning and regulation of financial flows. Therefore, at the present stage, the development of measures to develop management accounting and improve the management of financial flows of agricultural enterprises is a significant problem. Management accounting and management of financial flows is the management of cash (financial) flows arising in the process of promotion of tangible and intangible assets. Besides, in the process of management accounting there is a purposeful distribution of financial resources in the logistic financial system of an agricultural enterprise. Management of financial flows is carried out both for the internal environment of the agricultural enterprise and for the external environment. The aim of the article is the justification of theoretical provisions and development of organizational and methodical approach to management of financial flows of agricultural enterprises in the system of management accounting. Objectives of the research: to determine the main components, directions and mechanism of development in the management accounting of financial strategy; to develop a method of management accounting for management of financial flows of developing enterprises, planning to expand their activities in the long term.

Published: May 2020

The article is devoted to the topical issue of data processing in the database management systems. It presents a solution to the problem of finding paths in a graph using Dijkstra’s algorithm, set as a sequence of relational operations and functions of the Transact-SQL language. The efficiency of the known information system architectures and the impact of various ways of distributing functions between system components are reviewed. The article describes features of the relational algebra and the Transact-SQL operations, and provides a brief description of Dijkstra’s algorithm. For its programmatic implementation, several stages are defined, for each of which a formal description of the relational operations performed on it is given. The outputs of these operations are shown using the example of the database tables, and the algorithm to find the final path is given. The issues of the proposed method’s productivity and security of programmatic implementation of the path search in a graph are discussed separately.
