  • This article presents a methodology for calculating the basic parameters and selecting of centrifugal pumping units for filling (emptying) storages of liquid products (for example, vegetable oils). Centrifugal pumping units are widely used in the operation of tank farms for various needs of the national economy, in particular, for temporary storage of liquid products in sea and river ports when they are transshipped from land transport to ships, or from ships to land transport. As an example, the projected storage of vegetable oils in the port of Yeysk (Azov sea, Krasnodar region, Russian Federation) is given. The methodology includes the calculation of average fluid velocities, linear and local hydraulic losses in the intake and pressure pipelines, pipeline diameters, pump performance, the pressure created by it, electric drive power; equipment selection. Based on the proposed methodology, an algorithm has been created for calculating and selecting a pumping unit for transporting of liquid products from vehicles to a storage tank, or vice versa. The methodology and algorithm discussed in this article can be used in the design of storage facilities for various liquids at manufacturing plants, transshipment bases, etc.

  • All buildings with a significant service life must be regularly surveyed. This work analyzes the results of the inspection of the building of the compressor shop KC-1. Analysis of the design documentation and the results of measurement work showed that structurally the building has overall dimensions in plan along the outer axes of 21.0 × 72.0 meters. The height of the building is 17.0 meters. The conducted visual examination showed the presence of damages and defects of the third and fourth categories, which requires an instrumental examination. In particular, the need to determine the strength of brickwork and the strength of concrete in structures. The analysis of the results of the instrumental examination showed: the results of testing the wall masonry by the shock pulse method using the ONIKS 2.5 device showed that the compressive strength grade of the silicate brick of the compressor shop walls corresponds to M75 and M125, and ceramic M100. The grade of the masonry mortar for the walls of the compressor shop corresponds to M50 and M75; The results of concrete testing by the non-destructive method of strength control using the DigiShmidt2000 device showed that the compressive strength class of concrete in the reinforced concrete columns of the workshop corresponds to B20, in the girders B25, floor slabs and coating slabs B20. Verification numerical calculations on the computer of the bearing capacity of the building structures of the compressor shop building were performed taking into account the actual static diagrams, sections of elements, strength characteristics of materials established during the survey, and constant loads existing at the date of the survey. Based on the results of the verification calculation of the building structures of the transverse frame of the building, it was found that the bearing capacity of the upper chord of the truss was not provided. The bearing capacity of the building columns when calculating according to the first and second groups of limiting states is provided. In general, the analysis showed that the technical condition of the technical condition of the compressor shop KC-1 is unacceptable.

  • The purpose of the work is to develop an algorithm for analyzing the customer base of a trade organization, which allows customers to be divided into groups depending on their activity. In the future, by taking into account the preferences of each group of clients, it will be possible to increase the efficiency of working with clients. The authors use ABC-XYZ analysis and clustering methods in the algorithm, which make it possible to determine the most active customers who bring in the most profit. The ABC-XYZ analysis method divides buyers into groups depending on the amount and frequency of purchases, clustering methods combine the original objects into clusters based on similar characteristics. According to the algorithm presented in the work, RapidMiner Studio system has developed scenarios for analyzing the client base of a trade organization. The ABC-XYZ analysis method showed buyers who are worth paying special attention to, since their absence will lead to losses. The cluster analysis used the k-means methods, which divided the initial data set into 3 clusters, g-means and Expectation-Maximization algorithm, in which the number of clusters was not specified. The following characteristics were used: the average amount of purchases per year, the average number of unique products purchased per year, the average number of purchases per year, the number of years that the buyer cooperates with the store, the year of the last purchase. The g-means method divided the buyers into 3 clusters, and the EM algorithm into 10. The combined ABC-XYZ analysis and k-means algorithm showed the best results of customer separation, allowing an individual approach to work with customers of each group.

  • Text classification is one of the key issues in text development research, where documents are classified based on information under supervision. Since there is a considerable number of text classification algorithms, it is currently necessary to compile an overview list of them in order to simplify the orientation in the classification tools that are available at the moment. Many text representation schemes and classification/learning algorithms used to classify text documents into predefined categories can be found in the literature, but some of them require detailed analysis and unleashed potential. The purpose of this study is to provide an overview of different text presentation schemes and a comparison of different classifiers that are used to classify text documents into predefined categories. During the study, a comparison method was used as part of the methodology – modern classification approaches based on criteria, algorithms used and time complexity were compared, as well as methods of analysis, modelling and combination. As a result of the study, several algorithms or combinations of algorithms have been proposed for automatic classification of documents as hybrid approaches. The SVM (Support Vector Machine) classifier was recognised as one of the most effective text classification methods when comparing guided machine learning algorithms. It was concluded that SVM captures the inherent characteristics of the data and embeds the structural risk minimisation (SRM) principle, which minimises the upper bound of the generalisation error better than the empirical risk minimisation principle.

Semiconductor technologies for the implementation of radiation-resistant VLSI
  • 1Rostov State Transport University (Branch in Voronezh)

  • High values of photocurrents associated with instantaneous radiation can cause a transient voltage drop on the power buses, and some circuits are sensitive to currents generated in the element. This can lead to malfunctions ranging from temporary loss of functioning to data loss by memory and even to final damage to the product. The library elements are accessed at several levels of radiation, as for the design of elements, options for special simulation modeling and methods for creating topology. The article discusses the technologies of radiation-resistant ICS, their effectiveness on silicon-on-insulator structures, compared with a similar scheme on bulk silicon with the same design standards. Radiation-resistant semiconductor specialized devices with increased radiation resistance are also considered. Special attention is paid to the technology of implementation of radiation-resistant semiconductor storage devices. In relation to radiation-resistant logic devices, two directions are considered: the use of specialized logic circuits and user-programmable gate arrays.

  • Structures of a multi-storey frame building are considered as the object of the survey. Based on the results of the inspection of the technical condition of the object, verification calculations of the bearing capacity of structures for the effect of the design forces on the actual design schemes and on the action of real operational loads and influences were carried out. An assessment of the technical condition of individual structural elements of the object has been carried out. The actual technical condition of the building and its elements has been determined. Additional defects and damages were revealed that appeared in the investigated object at the stage of a forced interruption in construction. Quantitative assessments of the actual indicators of the quality of load-bearing building structures in the required volume for carrying out a variant design of the reconstruction of a building and making an informed decision about the possibility of its further trouble-free operation have been obtained. With the help of a verification calculation on a computer, diagrams of bending moments and shear forces, as well as diagrams and mosaics of longitudinal forces, were obtained for the considered axes of the cinema hall in the building. Based on the performed verification calculations based on the use of a finite element model, the obtained survey results and the performed assessment, it was concluded that the object under study is in a working technical condition.

  • The article describes a technique for obtaining experimental data for the purpose of optimal distribution of the forest transport network on a specific terrain model. Particular attention was paid to the issue of the operability of primary forest transport routes, in particular, the requirements for the strength of trunk lines, which is of fundamental importance when establishing the optimal distance between long-term roads. The operability of the trunk lines was experimentally investigated, while the scheme of the movement of tractors along the ring was used. Based on experimental data, certain values of track depth, relative humidity, density and the number of impacts depending on the number of passes were obtained. In the course of the experimental study, functional dependences of the increase in the depth of the track on the number of passages were established and calculated, taking into account the physical and mechanical properties of forest soils. During the tests, some fundamental differences were recorded in the process of track formation during the movement of wheeled and tracked tractors. It is important for the development of measures to reduce the seasonality of forest transport, especially during the autumn-spring thaw. Comparative tests of tracked and wheeled tractors when they move along a reinforced track have shown that a reinforced track when moving a wheeled tractor is able to withstand a significantly greater number of passes than when moving a tracked tractor. For the statistical evaluation of the experiments carried out, it was determined what errors could be caused by replacing the parameter with its point estimate. Analysis of statistical processing of the observation results showed that all the series, as a rule, correspond to the law of normal definition, which is determined by the ratio of the symmetry and kurtosis indicators to their average errors. These relations are determined within the limits of permissible deviations, therefore, asymmetry and kurtosis in this case do not matter significantly.

  • This paper presents a study of the applicability of the PERT method to the project management process of the microelectronics design center in comparison with the optimization mathematical model, which formed the basis of the software developed earlier. The study was based on corporate and cluster analyses of the projected results of project implementation by microelectronics design centers. The predicted values were obtained using a network model based on the PERT method and a mathematical model. To study the degree of similarity of the results of the network and mathematical models, we used a visualized proximity matrix constructed by the Ward method based on the criteria of the square of the Euclidean distance. The results are graphically represented by a similarity dendrogram. The paper illustrates the obtained dependencies of the implementation time on the totality of the number of simultaneously executed projects, the number of works and performers. The conducted studies have shown a significant correlation between the projected time of project implementation through network and mathematical models. That is, there is a direct relationship between the calculated time of implementation of mathematical and network model projects. Comparative analysis has shown that from the point of view of the minimum project execution time, the forecast of the PERT method network model is more flexible and relevant for managing small groups of projects.

  • The article analyzes fires in the Russian Federation, which are a complex physical phenomenon in conjunction with the physical features of the objects under consideration, on which the fire occurred. From the point of view of solving an engineering problem, a possible variant of the development of fires in a shopping and entertainment center is considered. It has been established that, despite a significant difference in the quantitative ratio, fires at objects with a massive stay of people, in comparison with fires at other objects, simultaneously affect a larger number of people, as a result of which they can have much more tragic consequences. As a result of the analysis carried out on the study of objects with a massive stay of people, in our case, at the proposed object of extinguishing a fire and carrying out emergency rescue operations, it can be noted that at the time of the fire there were quite a lot of people at the protection object. In this paper, when calculating the provision of resources for fire departments when extinguishing a fire using the example of the object under study, a mathematical model is proposed related to the structural model, where the object is represented as a system with its device and functioning mechanism. A scheme has been developed for the alignment of forces and means at the time of localization of the fire in accordance with the chosen scenario for the development of the fire. Modeling of a possible situation in case of fire was carried out on the example of the Passage shopping and entertainment center in Voronezh.

  • The problem of ensuring safety in case of fire of large objects is considered as a problem of engineering-oriented physics. The article discusses the concepts of the methodology for providing resources for fire departments in extinguishing fires and conducting emergency rescue operations. An algorithm of necessary actions in case of fire was obtained, including the provision of labor resources, material and technical resources and working capital. When extinguishing fires and carrying out rescue operations on large fires, and in our case at facilities with a massive stay of people, an algorithm of actions has been developed to provide resources for fire departments, for the implementation of which the rear is responsible in the person of the head of the rear. A mathematical model and methodology have been developed for providing fire departments with resources when extinguishing a fire and conducting emergency rescue operations using the example of the Passage shopping and entertainment center in Voronezh. We received an algorithm of certain actions that ensures fire extinguishing and emergency rescue operations, labor resources (fire brigade personnel), material and technical resources (fire vehicles, fire fighting and rescue weapons and equipment), working capital (gasoline, oils, foaming agents and other consumables). When extinguishing fires and carrying out rescue operations on large fires, and in our case at facilities with a massive stay of people, the rear, represented by the head of the rear, is responsible for the algorithm of actions to provide resources for fire departments. Recommendations were given to officials when extinguishing the fire in question. A scheme for the alignment of forces and means has been developed.

Multi-criteria optimization using local qualitative importance of criteria
  • 1Yuri Gagarin State Technical University of Saratov,This email address is being protected from spambots. You need JavaScript enabled to view it., This email address is being protected from spambots. You need JavaScript enabled to view it.

  • This article describes the research of the applicability of using the local importance of criteria in multi-criteria optimization problems. The theory of the global qualitative importance of criteria is currently well developed, there are many works on this topic. Moreover, numerous computer decision support systems (DSS) using global importance exist. However, the local importance of criteria is investigated very weak - there is no even mathematical definition for it. Authors have not been able to find in the public domain optimization algorithms and DSS using local importance. The authors start by formulating a mathematical definition for local criteria importance by adding specific limitations to the existing definition for global criteria importance. The next step is creating an iterative optimization algorithm that works with local importance criteria too. However, it is needed to check the applicability of this algorithm that is why authors create a DSS that realizes it. After a series of experiments, the authors conclude that the algorithm is applicable for real optimization problems.

Overview of logical bases and microcircuits in the construction of a combination device taking into account reliability
  • 1Voronezh State University of Forestry and Technologies named after G.F. Morozov

  • The fundamental laws of the positive algebra of logic are considered, including the rules relating to the elements of equivalence and non-equivalence. Logic gates used in practice are presented. The whole set of standard schemes is implemented, in particular, the frontal version, minimized, in the "OR–NOT" basis, in the "AND–NOT" basis based on the initial logical dependence: ¬(¬(A¬B) × ¬(¬CD) + ¬(¬AB) × ¬(C¬D)) + ¬(¬(AB) × ¬(CD) + ¬(¬A¬B) × ¬(¬C¬D)) . A combination device based on K176LE5 chips has been designed. It is noted that the implementation of this function requires at least 3 chips in the Pier basis, which is not optimal in terms of reliability and weight and size indicators. The transition from the minimized variant to the basis of "Non-Equivalence" + "Conjunction", as well as the basis of "Equivalence" + "Pierce function" is carried out. The results of the search for existing chips that implement the functions "Exclusive OR", "AND", "Exclusive OR–NOT" and "OR-NOT" are presented. 4 groups of chips were found, such as: chips based on logic with emitter coupling (ECL), based on transistor-transistor logic (TTL), based on a series of CMOS chips: with a supply voltage of 5-15 V, and also with a supply voltage of 3-5 V. The corresponding descriptions of each of the MC10H1xx chips (group 1 series); K155xx, xx74xx (group 2 series); K561xx, CD40xxxx (group 3 series); SN74LVCxxx (group 4 series) are presented. Implementation options for these groups of chips in both bases are presented. The cost analysis of the applied microcircuits is made. The calculation of the final cost of products is presented. The conclusion is made about the expediency of using one or another group of microcircuits, depending on the initial requirements set.

Development of mathematical models of physical processes in a heterogeneous multilayer structure under radiation exposure
  • 1Voronezh State University of Forestry and Technologies named after G.F. Morozov

  • The paper considers the processes occurring during the absorption of ionizing radiation energy. The task of developing mathematical models for determining the temperature of layers of a multilayer structure due to radiation absorption, the appearance of compression and tensile stresses, as well as tension associated with thermal expansion of the structure is set. It is assumed that the radiation energy is absorbed entirely in the beginning for a short period of time, and then it is redistributed across the layers. Each layer of the structure has its own initial and boundary conditions. Thus, the definition of a complex temperature profile is considered as the sum of some temperature profiles for simple problems solved analytically. The occurrence of stress in the structure is described by calculating the maximum value of the compression stress, the amplitude of the stress wave, as a result of which the expansion of materials can be observed. According to the proposed mathematical models, calculations of thermal and thermomechanical effects in a multilayer structure were carried out, the results of which are illustrated in the article by graphs of temperature distribution after exposure to ionization radiation, and stresses for different proportions of the thickness of the structure to its length.

Mathematical model of radiation energy absorption by multilayer structure and solution by grid method
  • 1Voronezh State University of Forestry and Technologies named after G.F. Morozov

  • When studying the radiation effect on microcircuits, the problem arises of calculating the absorbed energy. Often it comes down to determining the radiation resistance of microcircuits. However, in some cases it is necessary to determine the distribution of temperature and voltage in the chip housings. To do this, it is necessary to get an accurate picture of how the radiation energy was absorbed in each layer, depending on the coordinate. The paper considers the solution of this problem by the grid method, which allows us to calculate the energy absorption at each point of the multilayer structure. To do this, the placement of the chip in a three-dimensional coordinate system is considered, its multilayer structure is divided into nodes, in each of which the absorbed dose is calculated. The presented mathematical model describes the processes of absorption and attenuation of the intensity of the energy flow of -quanta. The model takes into account the processes associated with the transfer of energy between the regions for the photoelectric effect and the Compton effect. The proposed method is implemented programmatically, and the paper presents the results of calculating the absorbed dose in each layer of a multilayer structure. The advantage of the developed model and the method of its solution is to obtain the dose value at each point of the multilayer structure depending on the coordinates.
