Among other things, paraffin deposits on the inner surface of the SIKNS measuring lines (MLs), in which flow meters are installed have a significant effect. Direct measuring the paraffin layer thickness in the time of the SIKNS operation is impossible, however, there is a relationship between the ML flow and the line pressure and temperature, which depends on the presence of paraffin deposits.Studies conducted based on the mathematical model of the SIKN measuring line section developed in the Aspen HYSYS software environment have shown that regression equations, which relate the ML flow to the line pressure and temperature depending on the paraffin layer thickness can be obtained. To increase the model adequacy, the errors of specific measuring instruments involved in the metering process (pressure and temperature transmitters) have been considered. Assessment of the adequacy of the regression equations obtained has shown that the relationship and the equation coefficients are only significant for pressure, so the ML temperature cannot be used to analyze the amount of paraffin deposits in it. In general, the measures proposed in the article allow developing a high-quality procedure for evaluating the paraffin contamination of MLs to ensure their timely shutdown for washing that will improve the crude oil metering accuracy.","PeriodicalId":101834,"journal":{"name":"2020 International Russian Automation Conference (RusAutoCon)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115626696","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods and algorithms for determined and multivariate analysis, obtaining the coefficients of influence and elasticity of factors, approximating the contours represented by time series are proposed. Modified component schemes of the NN, training algorithms, developed a software package (SP) for visualization, recognition, classification of images of pollen grains, implemented a hybrid identification model taking into account the non-linearity of the effects of factors under the condition of a priori insufficiency and uncertainty of parameters. The efficiency of the SP was studied on the basis of a three-layer NN of forward and backward propagation of errors, learning algorithms with and without a teacher, Kohonen network with procedures for vector quantization, clustering and segmentation and the formation of a \"sliding windows\". The results of image identification in the presence of \"noise\", optimization based on filtering systematic error and NN extrapolation of the trend of the contour curve of the images of pollen grains were obtained.","PeriodicalId":101834,"journal":{"name":"2020 International Russian Automation Conference (RusAutoCon)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120967123","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

If N = 2k = 20, the method based on majority decoding yields more than double the gain. The results show that the choice of the length of the processed segment of the PRS N with an increase in destructive errors affects the average search time. The well-known works [2] do not study the phasing characteristics in short segments of the bandwidth, although it is obvious that with an increase in destructive errors one cannot simply increase N, since there are cases when the synchronization system will give worse characteristics compared to synchronization with respect to Ward’s method, or not provide a minimum of average search time for memory bandwidth Accordingly, a method based on majority decoding should, at a certain probability of error, synchronize the PRS over a certain definite segment of the PRS of length N. Therefore, it is necessary to modify the search method based on the majority processing of synchronizing information in order to increase its efficiency and optimize the synchronization mechanism.","PeriodicalId":101834,"journal":{"name":"2020 International Russian Automation Conference (RusAutoCon)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130537026","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For the implementation of modeling, a mathematical application package Scilab (version 6.0.1) is used. Reagentless treatment of geothermal water in the heat supply system with an acoustic-magnetic device can significantly reduce the intensity of scale formation in the heat exchanger and heat exchange equipment. It provides conditions for the automation of geothermal heat supply of greenhouses with a surface heat exchanger. Based on the results of the simulation, the optimal mode of operation of the heat exchanger automation system was developed. Using an automation system allow with greater accuracy and reliability to maintain the required temperature regime in the greenhouse, reduce the frequency of system shutdown for unplanned cleaning of the heat exchanger, reduce the complexity of manual operations of heat exchange equipment maintenance (removal of sludge, scale) and reduce the economic costs of transportation and heat consumption.","PeriodicalId":101834,"journal":{"name":"2020 International Russian Automation Conference (RusAutoCon)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126999018","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition, modern technologies allow the processing of lunar soil into refined materials that can be used for 3D printing of modules for space bases or ships. The basis for modeling of the mobile Complex is the Kerbal Space Program – an engineering game aimed at familiarizing with the complexities of space exploration. The first version of the program was developed in 2010 by the Mexican company \"Squad\", the lead developer – Felipe Falanghe. In 2019, the project has been supported by the American developer of the GTA series of games. Now the program goes beyond using only by interested users. In the new version of the educational paradigm, it is proposed to include elements of computer games and simulations in the content of training courses. The application of the Kerbal Space Program in the educational process in technical disciplines solves the problems of attracting potential specialists to the space industry, as well as the development of \"space\" literacy, especially for young students. The development described in the article is brought to detailing at the level of individual modules and their components, a program for deploying of the Complex on the surface of the Moon is proposed, and calculations are performed that demonstrate the realism of the proposed idea.","PeriodicalId":101834,"journal":{"name":"2020 International Russian Automation Conference (RusAutoCon)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129095246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
