Abstract: The reform of the waste products distribution touches many aspects. The questions of the rational or-ganization of the waste transportation are actual for the all-Russian regions. The one of the directions of the development territorial arrangement is a reduction in expenses for fuel waste delivery to the waste polygons or the places of their utilization, a tariff cut for the citizens. For developed the under-lying territorial scheme of a waste management we need the carrying-out of an analysis and the waste direction control with consideration to the waste formation dynamics, the spatial features of the munic-ipal territories, accumulation rate determination of the waste on the polygons. Specialists solve the problem of the road complexation of the refuse transport for the electronic model development of the waste management scheme. The paper has a look at the number of the most identified models and ways to the material allocation in the spatially-regular system. There is an estimate of its using for modifying of the territorial scheme of a waste management. The specialists recognized that one of such approach-es must not directly use to the waste management. The using the well-known algorithms of the transport logistic disabled to take stock of the combination of the factors, representative for a mature model in a transportation of waste region. There needs their combination and refinement. There is a collection or-ganization description, utilization and waste disposal, and a direction control of a municipal solid waste from the local centers to the polygons. The authors showed the algorithm of the complexation cargo transportation route. There is a script package based on the offered algorithm, with help of this the specialists made the analysis of the mod-eling waste transport flows. The complexation results of the march allow developing the whole and consistent electronic model of the territorial waste management scheme.

Abstract: Metal forming is widely used in the manufacture of products for various purposes. There are crimping operations with the help of a technological tool of crimping matrices to reduce the transverse dimen-sions of the end part of hollow thin-walled cylindrical parts. Receive a crimped cap of cylindrical cans, aerosol containers packaging, different adapter pipes and other products. The high costs of experi-mental work and production of pilot batches lead to the relevance to create automatic engineering sys-tem of the crimping operation techno - process. The article presents a business processes sequence UML-diagram of the designing crimp matrices. The purpose of setting up the production technology, of course, is to get such sequence in which the product information will be the least time to get to the work department with the customer without re-turning to the design stage. This, in particular, requires fast and accurate automated control at the key stages of production. The authors describe in detail the interface and the operation principle of the computer-aided design software module of the crimping technological process. There are the formulas for calculating the number of crimping operations, the presentation structure of the basic data. The de-scribed algorithm allows the flexibility to assign the processes parameters of the deformation and to control the strength characteristics of the functional products. The developed software for the design of the crimping process allows the calculation of parameters such as the operation number and the sys-tematic diameters of the crimp dies. For modeling in finite element analysis system, we can use the program output data. The authors made a conclusion that the combination of the developed application software and systems of finite el-ement analysis will significantly reduce the production time and cost by reducing the time required for the design of the crimping process, reducing the sets of experimental technological tools.

Abstract: The paper proposes an algorithm for searching the parameters values deviations from industrial equip-ment norms in the context of statistical and fuzzy source data to further equipment diagnosing at the operational stage. The authors proposes generalized search pattern deviations of the industrial facility parameters with database using (technical data sheets, GOST standards and regulatory documentation), as well as the knowledge base containing the staff’s knowledge and experience of the equipment pa-rameters values, factors that may affect the equipment performance presented in the form of verbal de-scriptions and intervals. The authors proposed the algorithm, which searches the mistakes of parameters from the industrial facility norms with using of database. This algorithm in the decision support systems decision support systems for equipment diagnostics makes it possible not only to identify the time when the parameter value deviation occurred, but the duration and the average value of the parameter deviation as well. This paper describes an infological data model (a description of entities) with a set of attributes and re-lationships among them, which are in the process of researching both input and output data, as well as a logical data model (a display of logical relationships among data elements). As an example, there are the screen forms of the user interface of the developed software system in the C # programming lan-guage for searching deviations of parameter values. Using of the developed software will provide the staff on duty with the following: 1) lack of neces-sity to constantly access the technical data sheets, GOST standards and regulatory documentation pre-sented in paper form; 2) rejection of an option to choose possible causes of deviations; 3) elimination of unreasonable equipment repairs.

Abstract: The paper deals with the problem of modeling the liquid and gas flow in systems consisting of contain-ers of various volumes interconnected by pipes of various lengths and widths. The proposed model is based on a system of differential equations describing the change in sub-stance mass in containers as well as the change in the substance flow magnitude in pipes. In addition to container and pipe parameters, the model takes into account various parameters of liquids and gases, such as density, temperature, and molar mass. The description is accompanied by formulas with neces-sary explanations. The paper also discusses the problems caused by high computational costs to run such models, time costs. It proposes a number of heuristics to reduce those costs significantly. The authors discuss each idea, interconnections between applications of the ideas, as well as their limitations. The authors describe the key technical aspects of model implementation, including the proposed heuristics and the ability to configure various parameters that affect the accuracy of the calculation and its running time. The paper shows that the proposed model can be extended by adding the elements that model the operation of various devices, such as valves, gearboxes, and pumps. Each device has an implementa-tion model. Finally, the scope of the model and a computer implementation are discussed. The authors also mention some issues beyond the paper scope, such as implementation of parallel computing.

Author: N.V. Zvyagintsev (n.zvyagintsev@gmail.com) - Tver State Technical University;
Abstract: Chemical reaction is a complex system by a number of factors determine its effectiveness. Assessing the effectiveness of XP in various conditions is an important task. It allows to search for effective con-ditions and to predict the possibility of the reaction under certain conditions. In this paper, there are neural networks to assess the condition effectiveness of the chemical reac-tion course. The author analyzed in detail the conditions that the most significantly affect the chemical reaction course. The author proposed the methods for encoding information about the reaction condi-tions. The author proposed to divide the reaction conditions into two groups – data that can be encoded in binary form and data that must be considered in numerical form. As a prediction tool, the author used the neural networks with perceptron architecture, requiring training with a teacher. As data for teaching neural networks, we can use as experimental data on the сhemical reaction course, as well as the results of the computer simulation reactions. The paper considers two approaches for predicting the chemical reaction effectiveness. The first approach involves the neural network use for the direct prediction of product yields, considering the product yields of chemical reactions as a function of the input set parameters. Another approach to the building a neural network model of сhemical reaction is to build a classification of the conditions for conducting chemical reactions, dividing the input parameters into pre-formed groups based on expert knowledge. The authors tasted this procedure on the industrially important olefin carbonylation reaction, the industry widely use it. For modeling, the author developed the software that allows importing data on сhemical reaction, to carry out training and forecast.

Abstract: The paper proposes the structure and the main automated system modules for calculating the annealing modes of glass products. There is the problem of modeling temperature fields for cylindrical products with asymmetric con-vection-radiation heat exchange with the environment and enclosing surfaces of technological equipment. The au-thor formulated the possibility of solving the two-dimensional temperature problem in the Matlab programming environment. There was the parabolic function in the performance of the temperature field-modeling problem in cylindrical glass products. This is one of the Matlab tools for solving differential equations of parabolic type with complex boundary conditions. There are the programs based on the standard fmincon function in Matlab that allow to identify the coeffi-cients of artificial convective heat exchange between the air and the product surface in each of the zones by using the determinate thermal material characteristics and the temperature-time regime parameters in the annealing fur-nace. There is a parameter identification example of the convective-radiation heat transfer in the sort glassware (glasses) annealing furnace based on the temperature field-modeling program in Matlab. The author considered the program development features associated with the need to take into account the changing initial and boundary conditions at each temperature-time stage annealing of the product. There are the program codes of the main program, the modeling temperature field functions the CilinderHolParabolic1 and the boundary conditions boundaryFileHolParabolic1. The author studied the program results and demonstrated a good match of the convective heat transfer coefficients with their physically reasonable values in artificial convec-tive heat exchange in annealing furnaces of glassware. The attained condition identification results of the convec-tive-radiation heat exchange with the environment and enclosing surfaces we can use to optimize the heat treat-ment of cylindrical products.

Abstract: The paper describes the software, which the authors developed. It is for solving the problem of finding the kinetic parameters of chemical reactions. In the conditions of modern industrial production, meth-ods of mathematical modeling of chemical-technological processes are widely used, which allow solv-ing the problems of forecasting and optimizing production at the stage of a computational experiment. To solve these problems, we need the mathematical description of the chemical process, which relies on the construction and observation of the kinetic model of the chemical reaction. The relevance of software development for solving the problem of searching for kinetic parameters of chemical reactions is due to large computational and time costs. The software developed by the au-thors uses the differential evolution method and allows calculating the values of preexponential factors and activation energies of the user-entered reaction from the experimental values of the concentrations of substances. Based on the found kinetic parameters, the authors construct a kinetic reaction model and solve the direct kinetic problem. The calculation results are in numerical and graphical form. For appraisal the proximity of the obtained solution of the direct problem with the experimental results, there are the experimental and numerical values of the concentrations of substances, as well as the val-ues of the relative errors of the concentrations on one graph. Software package approbation of the kinetic parameters calculation was the case of the phthalic an-hydride reaction. In view of the results, there were implications about the satisfactory agreement of the experimental data with the concentrations calculated because of the calculated kinetic parameters. We can use the software tool during the computational experiments in scientific and production la-boratories at the design and modernization stages of chemical processes.

Abstract: The article discusses the development of algorithmic and software for an intellectual control system for the development of the synthesis of active pharmaceutical ingredients. Based on the analysis of the scheme of the quality control system, the efficiency and safety of medical products, the authors showed that the only non-certified stage in the life cycle of the development and production of medi-cines is the pharmaceutical development stage, which includes the APIs synthesis and the GLF compo-sition development. The authors showed the advantage of the continuous synthesis scheme for the production of active pharmaceutical ingredients over the periodic synthesis scheme. The authors gave a systematic ap-proach to the proposed development based on the implementation of the QbD principle. They devel-oped a scheme for the formation of a global criterion. The authors formulated a range of conditions in which the research is to be performed, while with respect to each condition, the quality of functioning is evaluated by an independent criterion. There are the information models for the control system for the continuous synthesis of diphenhydramine APIs in the IDEF0 notation. The authors proposed an approach to the development of information and software and algorithmic support for the continuous synthesis of drugs. The authors developed the mathematical models based on regression analysis to control the process of continuous synthesis using an intelligent control sys-tem. There is the algorithmic and software based on the freely available Scilab software package for managing the process of developing API synthesis using multi-regression regression models and the Hook-Jeeves optimization algorithm. There is a graphical interpretation of some of the process study results of obtaining the API of di-phenhydramine (diphenhydramine) in an experimental continuous synthesis plant. The authors ob-tained a set of graphic solutions that allows to optimize a number of the synthesis process quantitative indicators of the active pharmaceutical ingredients.

Abstract: Continuously increasing amounts of textual information makes the problem of semantic text pressure more and more important. Relations between discursive markers in a text set the hierarchy, which al-lows solving the various text-processing problems in natural language, including the problem of the au-tomatic gist abstracting from high-cube text. This article describes the original method of auto reviewing of scientific and technical texts based on rhetorical analysis and using topic modeling. The suggested method combines the usage of a linguis-tic knowledge base, graph representation of texts and machine learning. There is a topic modeling for the detection of essential terms. First, there is a producing of unigram topic models. They contain only one-word terms. Further, these is an expansion of these models by adding multiword terms. The determination of the most important fragments of the source document are in the process of rhetorical analysis with the help of discursive markers. Representation of texts in the form of graphs helps to demonstrate the transformation with the text necessary to extract important fragments. In assessing the importance of text fragments, keywords, multiword terms, and scientific lexicon characterizing scientific and technical texts are also conceded. The creating of the linguistic knowledge base was for the data storage markers. The final step of developing abstract is smoothing – a procedure that makes the text of the summary more coherent and consistent. As the experiments showed, the proposed method is effective and can be adapted for processing texts of different subjects in other languages.

Abstract: Information technologies are in all spheres of society. They are effectively takes root in the work of fo-rensic experts and criminologists. The use of specialized software can significantly improve the effi-ciency of solving practical problems, and the scientific validity of the conclusions obtained because of examinations. This article contains the algorithm description and the software complex FFRACE, intended to the individual race diagnostic on externally – the head identifying characteristics. The proposed diagnostic algorithm consists of three stages: fixing the basic values externally – identifying features of the indi-vidual head and their numerical score; the probability calculation of belonging to a particular race based on iterative Bayesian Procedure in the modification of A.A. Genkin; establishing racial identity of the individual, taking into account the critical rules. Using the algorithm, the authors developed the unique program complex. This program complex consists of three modules: module for entering basic information; module fixing externally – head identifying signs; module for the race diagnostic. The result of the race diagnostic in the program complex is an expert opinion, which contains a ta-ble of the individual personal information; development variants of each fixed feature; the occurrence probability of this option at the caucasian and mongoloid; the calculated probability of the investigated individual race at each step; final conclusion about the race. If the individual’s race is indescribable, the expert, analyzing the data in the table, can determine the predominance of mongoloid or caucasoid appearance. The software package is for use in laboratory studies, and the location of emergency inci-dents.
