Development of the patent array analysis module based on the “Problem-Solution” model
Authors: Kochura O A , Korobkin D M , Fomenkov S A , Kolesnikov S G 
Published: February 2021

Abstract
In the modern world, there is a description of many technical solutions in different types. A patent is one of these types. Analysis of the patent array based on the “Problem-Solution” model allows not only to analyze existing technical solutions, but also to improve the characteristics of individual elements of a technical object and, accordingly, the technical object (TO) itself. To do this, you need to detail the structural-functional structure of the TO, i.e. define the elements (components) of TO and the functions of the TO elements. To extract descriptions of functions of a technical object, we use the semantic construction “Subject-Action-Object” (SAO). If “Action” is an attributive verb, such as “reduce”, “improve”, “increase”, etc., then “Subject” can affect “Object” as a problem or need. The SAO structure can be organized in the “problem-solution” format, where the “Object-action” (AO) forms the problem or need, and the “Subject” (S) sets the solution. Structured data will be extracted from natural language text using the Yandex Tomita-parser technology. Then, after all the procedures, it is advisable to fill the database with the information obtained for convenient analysis and search.

Published: February 2021

Abstract
The paper deals with the problem of decision-making support for digital production planning. The analysis of the stages of organization and production planning currently is poorly represented in existing software solutions. Main stages of digital production planning are identified such as optimization of manufacturing placement; optimization of suppliers selection of resources and its delivery to the place of manufacturing. Taking into account the conditions of the modern stage of development of technologies for the digital production, we can identify the key requirements for the functionality and use of the software platform. The formalization (ontology) based on the approach of production and operational management and the architecture of a digital cloud platform and its functional modules has been developed for the digital production planning process. It is a decentralized platform as a public network consisting of independent software modules (cloud services), connected into a tool with expandable number of modules. The software tool consists of production-planning unit and production-management support unit. Currently, a number of modules of the system have been developed and experimentally tested; now we are developing the full-featured tool.
System-objective representation of conceptual knowledge with description logic
Authors: Matorin S I , Zhikharev A G , Mikhelev V V 
Published: February 2021

Abstract
The paper describes the possibilities of applying the system-object approach “Unit-Function-Object” in terms of descriptive logic for describing conceptual knowledge. Conceptual knowledge is represented using a hierarchy of conceptual systems. The syntax and semantics of the descriptive logic ALCOIQ and SHOIQ were described. These allow us to justify the structure of the hierarchy of class systems and the mandatory implementation of the principle of monocentrism for conceptual systems. The concepts of “volume” and “content” of systems-classes were introduced. The results allow us to improve the existing ways of presenting conceptual knowledge, as well as develop models of conceptual knowledge that reflect the systemic reality that exists when solving classification problems.
The Edgeworth-Pareto principle in the case of IT2F preference relation
Authors: Baskov O V , Noghin V D 
Published: February 2021

Abstract
The multicriteria choice problem is considered, which includes a set of feasible alternatives, a vector criterion defined on this set and a fuzzy preference relation of the decision maker. It is assumed that this relation is an interval type-2 fuzzy relation. For this problem, a set of nondominated alternatives is introduced, certain axioms of reasonable behavior of a decision maker in the decision-making process are formulated, and the Edgeworth-Pareto principle is established, according to which the best choice should be made only within the Pareto set.

Published: February 2021

Abstract
In the course of the work, the systems modeling the dispersion of pollution were considered, where, based on the theoretical analysis of their characteristics and properties, the “Calpuff” model was chosen, which is most suitable for modeling air quality in urban areas. As a calculation model of emissions near roads, the Russian “Methodology for determining emissions from motor vehicles for conducting summary calculations of urban air pollution” was chosen. Developed a process for the preparation of the data on pollution from road transport for the system modeling “Calpuff”. In the high-level object-oriented language Python, a calculation module has been developed that performs the functions of storing, hourly averaging of pollution and generating the lnemarb.dat file of the “Calpuff” model. A graphical interface has been developed for the user of the software module.

Published: February 2021

Abstract
The social policy of the state is for the most part aimed, at people, without any physical deviations. The needs for people with disabilities can be roughly divided into two groups of needs: those characteristic of ordinary citizens and the needs that cause illness. The development of these information technologies is a particularly valuable tool for people with disabilities; they can improve their quality of life. Despite the fact that there is still an acknowledged digital divide, it is now much smaller. For large numbers of people with disabilities, information technology is essential to develop the basic literacy and numeracy skills needed to participate more fully in society. For people with individual learning needs information technology is applicable to integrate into society through the process of socialization and control of unacceptable behavior.
An approach to solution of constrained clustering problems using the constraint programming paradigm and the multiset theory
Authors: Zuenko A A , Fridman O V , Zuenko O N , Zhuravleva O G 
Published: February 2021

Abstract
An integrated approach is proposed to solve the Constrained Clustering problems which are oriented on taking the opinion of a group of experts into account. A cluster and the objects to be clustered are proposed to be represented as multisets, and the distance between these to be determined by metrics in the Petrovsky multisets space. The approach is implemented within the Constraint Programming paradigm. In so doing, the significant complexity is in organizing effective processing the qualitative constraints, namely, the rules for assigning the objects to one or different clusters. The qualitative constraints are proposed to be represented and processed as table constraints of a new type, i.e., as the smart-tables of D-type. The main attention is confined to the problem of how to reduce the amount of constraints and how to simplify the Constrained Clustering problem. It is proposed to generate constraints for some pairs of objects rather than for all of them, with the generation based on a priori interval estimation of the optimal value of the clustering criterion. To do that, a modified method of multisets hierarchical clustering has been proposed. The approach proposed allows a global optimum to be found for the Constrained Clustering problems considered.

Authors: Tomakova R A , Egorov I S , Tomakov M V , Korsynskiy N A 
Published: February 2021

Abstract
The purpose of the research is to create new informative Internet technologies that would provide creators of intellectual research systems with available information for constructing training and control samples. An information and diagnostic system based on the formation of a unified structured knowledge base, which is intended for the analysis and classification of X-ray images, is proposed. Research methods for the developed information technology for the synthesis of X-ray classifiers are “the Interior”. The Interior can be presented as a computer program, an autonomous Interior agent, which allows interactively carrying out research on meta-analysis of the classifiers efficiency. The function of the Interior is to build an X-ray classifier with the connection of many users with different databases.
The result of the research is the formation of a unified structured knowledge base. The basis of the Interior is a DBMS containing: image files, files of marks of morphological formations, files of personal data, files of meta-analysis results, and files of classifiers. Integration into interiors-associates allows you to build a distributed system of intelligent agents. Based on this system, it becomes possible to form classifiers for global use, as well as to carry out a meta-analysis of the diagnostic procedures effectiveness.

Abstract
The paper presents an experience of using orthogonal hexahedral meshes for simulation of different processes in machine-building products. Stress state of the details of suspension of a cargo vehicle during the movement on random road profile was simulated. Orthogonal hexahedral meshes for lower suspension levers and housing and piston rod of shock adsorber were used. Thermal state of the elements of drive axle and its housing during the movement of a cargo vehicle with constant speed was calculated using hexahedral orthogonal meshes for details and inner volume of housing of the drive axle. Lubrication fluid circulation in the reducer of a cargo vehicle was modelled. Orthogonal mesh for inner volume of the reducer was used to calculate the parameters of lubrication fluid circulation.

Published: February 2021

Abstract
Skopje has unique examples of modernist architecture that play a major role in creating the new identity of the city, which was completely lost after the earthquake in 1963. In the last decade, awareness has been raised that modernist buildings deserve to be protected as cultural monuments. On the other hand, concerning energy efficiency and sustainability aspect, they were built without thermal insulation and thus have extremely poor thermal properties. In order to improve the energy efficiency, retrofit interventions are constantly being implemented and their authentic appearance have been changed. Many buildings have already been changed to an unrecognizable stile which threatens the overall architectural identity of the city. Therefore, systematic research has been done on 50 valuable buildings from the period of Modernism in Skopje. The buildings are selected according to their architectural, structural and cultural-historical values. They are analysed from following aspects: construction, building materials, thermal properties, function, cultural heritage protection, level of authenticity degradation, preservation and retrofit measures. The purpose of this paper is to define the most common types of buildings, which are in same time the most problematic in terms of energy efficiency, sustainability and authentic appearance.

Published: February 2021

Abstract
The results of a two-factor field experiment on the application of two elements of organic planting: sowing of inter-row spacing and introduction of biofertilizers – microbial preparations for increasing soil fertility, growth and productivity of grapes (Vitis vinifera L.) of Chardonnay cultivar on rootstock cultivar Berlandieri x Riparia Kober 5BB (Kober 5BB) are presented. Study was carried out in 2016-2018. The intercropping factor has two options: natural overgrowing (NO) and sowing a mixture of grasses (MG) – pasture ryegrass (Lolium perenne L.), alfalfa (Medicago sativa L.) and meadow bluegrass (Poa pratensis L.) in a ratio of 1:1:1. For the factor microbial preparations (MP): Diazofit – Agrobacterium radiobacter 204 strain, associative nitrogen-fixer, and a complex of microbial preparations (CMP). It has been established that use of organic methods positively influenced the growth, productivity and quality of Chardonnay grapes in the foothill zone of the Crimea. MP provided the most significant effect on these indicators against the intercropping with a mixture of grasses. The applied methods of biologization contributed to an increase in the sugar content of the grapes, to a greater extent the MP and reduced the acidity of the berries juice, where intercropping played a significant role. The increasing in soil fertility under the vineyard with the application of intercropping and MP on its background has been revealed. Model of Chardonnay variety productivity on rootstock cultivar Kober 5BB in the conditions of the foothill Crimea by organic viticulture methods was constructed.

Published: February 2021

Abstract
The article deals with the state support optimization for the personal subsidiary plots activities as the state food security system element. In the context of counter-sanctions and a pandemic, the country’s self-sufficiency in food is the most important aspect of state policy. And to solve this problem it is necessary to involve all types of agricultural producers, including households. The paper proposes to improve state support for personal subsidiary plots, taking into account the distance to sales markets and the manufactured products marketability. The proposed mathematical apparatus makes it possible to calculate the subsidies amount, both for individual settlements and for individual households. The subsidies calculated amounts for the Kinel-Cherkassky district showed that their value, depending on the location of settlements, should increase by 16% in the whole district. The state support funds distribution to private households will require additional subsidies in the Samara region in the amount of 1.2 billion rubles and will ensure the growth of the region’s self-sufficiency in agricultural products at the level of 80% or more. Agricultural production in the personal subsidiary plots sector of the region will increase by 18 billion rubles and will amount to 53080.7 million rubles. Growth will be noted not only in the subsidized livestock sector, but also in crop production due to the synergistic effect (the need to grow fodder, crop rotation observance, free capacities use, etc).
Mapping and forecasting of changes of eroded soils (Central-chernozem region of Russia)
Authors: Zhidkin A P 
Published: February 2021

Abstract
The paper presents assessment of the current state and risk of soil degradation of arable land (area ~800 sq. km.) from erosion. The rates of soil erosion were calculated by the WATEM/SEDEM. The obtained rates of soil erosion were converted into erosion losses of the soil profile and compared with the current thickness of the humus horizons (according to field survey data). The calculated and actual (according to the field survey) soil losses correspond to each other. The rate of soil erosion in the southern section is almost twice higher than in the northern section, however, the difference in the area of eroded soils is 4.4 times higher. The forecast was calculated for each pixel with respect to the current thickness of the humus horizons. With the stable rate of erosion in the next 50 years, the area of eroded soils will almost double on the studied territory, and in 200 years will grow almost 3 times relative to the current state. After 200 years of plowing without soil protection measures, the share of eroded soils in the northern section will only reach the current level of soil degradation in the southern section, while the share of eroded soils on south section will reach almost 35%. These results clearly demonstrate that the areas of priority application of soil conservation measures should be determined not by the rate of erosion, but by the rate of degradation of the soil cover from erosion.

Published: February 2021

Abstract
The article considers the main study, methodological provisions in the field of road landscape zoning, as well as the theory and practice of physical and geographical zoning. A new definition of the road landscape is proposed including the main taxonometric units of road landscape zoning, accept the road landscape and road micro landscape. The relationships between various physical and geographical units and the “monosystem model” of the natural complex are analyzed. An assessment is given of the degree of influence of the components of the geographical environment and the engineering structure, which made it possible to determine territorial complexes with varying complexity of road construction conditions. The problem of ensuring ergonomic and aesthetic requirements and changes in the natural complex as a result of the inclusion of an engineering structure in it are also considered. Since the geographical environment and the engineering structure were considered as the object of study, respectively, as a model for the study we chose a set of information about the geographical environment and the design of the engineering structure. One of the important issues of road-landscape zoning is touched upon - the problem of classification of territorial complexes. The recommendations are given on the use of statistical methods of study while substantiating the role and influence of the characteristics of components in the system “Geographical environment - engineering construction”.
Justification of the parameters and operating modes of the disinfecting system
Authors: Levshin A , Gasparyan I , Sychev V , Bitsoev B , Shchigolev S 
Published: February 2021

Abstract
Increasing yields is an important task for our country. This is possible due to removing the tip of the shoot, which stimulates the potential of the plant itself, and such products can be sold as organic since no other chemicals are used to increase yields. When the shoot tip is removed, a wound is formed through which pathogens can enter. To reduce the likelihood of plant contamination, the device provides a system for applying a disinfectant solution (hydrogen peroxide) to the knife blade. The settings of the injector are taken into account. When choosing a spray gun, it is necessary to take into account the average working pressure, equal to P = 0.28 MPa, which provides a solution flow rate щa Q = 0.8 l • min-1 with a nozzle diameter of 0.1 mm. These requirements can be met by spray guns of caliber 04 or 05. At a spray angle of 800, the recommended spray angle is 300; the mounting distance is 0.3 m below the plane of rotation of the cut-off wheel. The initial flow rate of the liquid of 17.33 m • s-1 will provide stable droplet formation, providing the recommended dispersion of the solution of 150-200 microns.
Soybean harvesting using current dedicated headers and adapters

Published: February 2021

AbstractThe article describes the basic agrotechnical requirements for soybean combine harvesting. The current model range of adapters and headers used by agricultural producers for harvesting is analyzed. The design features and purpose of the headers and adapters to be used are studied. The results of experimental studies using dedicated soybean harvesting headers manufactured by Rostselmash in the real economic conditions of the Southern Federal District of the Russian Federation and a theoretical calculation of the optimal length of the header table are presented. Studies of combine harvesters from Rostselmash (Nova 340, Vector, TORUM) having various designs of threshers (single-drum; axial-flow) have shown that RSM-181 TORUM 750+ZhSU-900 and RSM-181 TORUM 740+ZhSU-700 combine harvesters have high productivity per hour of the main period equal to 5.20 and 4.80 ha / h respectively. This can be explained by the presence of a large working width header, a high speed of movement and an axial-flow thresher used on the combine. When harvesting long-stalked soybeans, the length of the header table is of great importance, which determines the reliability of the header auger, the uniformity of the plant mass supply to the combine thresher. As a result of theoretical calculations, it was established that the header table length should be L_ht≥0.81 m. Manufacturers of current headers recommend replacing a serial length table with a table having an extended length when harvesting long-stalked soybeans.
The efficiency of applying soil hydrogel to the light-chestnut soils of the Volga and Don inter stream area to stimulate seed sprouting for agricultural crops

Published: February 2021

Abstract
The conducted research reveals that the introduction of hydrogel into the topsoil using conventional grain seeders facilitates the retention, accumulation, absorption, and differentiated distribution of soil moisture, and stimulates and accelerates the seed sprouting for agricultural crops. The use of a scientifically calculated hydrogel dosage (80 kg/ha) during the seeding period led to a 2.08-3.77 mm increase in the productive moisture content in the topsoil as compared to the plots without hydrogel. The plants in the field treated with polymer agents used 3.54-7.35 mm less soil moisture to sprout, which led to a 44.25-61.40% economy of water as compared to the untreated reference plots. The hydrogel plantings began sprouting earlier, between the 2nd and the 4th days, and their field survival was 7.2-28.6% higher, which influenced the further vegetation of the plants.
