The problems encountered in the diagnosis of industrial equipment (IE), theoretical provisions for the construction of models for diagnosing equipment and requirements for models built are considered. The authors proposed a comprehensive approach based on the building heterogeneous cognitive models (HCM) and mixed production rules for processing diagnostic information (DI) obtained from measuring instruments and experts. HCM here is a directed weighted graph with marked vertices and edges with various types of factors and relationships. A model in the form of HCM for diagnosing electrical equipment (EE) in the oil industry is proposed. As an example, a script of possible risk situation developments related to the equipment developed using pulse modeling, and its analysis are presented. The proposed approach allows one not only to calculate the predicted values of the controlled parameters of the equipment, but also to increase the accuracy and completeness of the IE diagnostics. It takes into account not only the measurement data, but also the knowledge from the duty staff, the chief engineer, which leads to the IE timely repair and maintenance.","PeriodicalId":122716,"journal":{"name":"2020 Moscow Workshop on Electronic and Networking Technologies (MWENT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129790504","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}

It was determined that the main technological factors for producing textured ZnO and AlN films on silicon substrates of different orientations by magnetron sputtering are the substrate temperature and the working gases pressure. The crystallization features of thin films of lead zirconate titanate (LZT) deposited on Si / SiO2 / Pt substrates at low temperatures by the method of RF magnetron sputtering are studied. It was revealed that, after low-temperature deposition of LZT piezoelectric films, the pyrochlore phase with non-ferroelectric properties predominates in the structure. It was found that for the formation of the ferroelectric phase of the PZT perovskite, continuous annealing at relatively high temperatures is required.","PeriodicalId":122716,"journal":{"name":"2020 Moscow Workshop on Electronic and Networking Technologies (MWENT)","volume":"198 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114617699","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}

There is a need for sampling and analog-to-digital conversion of the output voltage of the active transducer in order to generate the output signal of the measuring circuit using digital nodes. Since sampling is carried out over some period of time, rather than instantly, during which the analog signal manages to change, this leads to the appearance of an instrumental error due to imperfection of sampling. To eliminate the indicated error, it is proposed to use piecewise continuous test signals in measuring circuits of sensors, which provide invariability of the output voltage of the active transducer during sampling time. Variants for mathematical description of functions of piecewise continuous test signals are considered, and their comparative analysis is carried out.","PeriodicalId":122716,"journal":{"name":"2020 Moscow Workshop on Electronic and Networking Technologies (MWENT)","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134012504","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}

Often for this assessment, you can choose one characteristic parameter that determines the state of the object as a whole. The paper shows the possibility of using Poincare diagrams to track changes in the state of a technical object in real time. Poincare diagrams of any dynamic processes are characterized by asymmetry with respect to the center or axes of the coordinate system. In the modeling process, a time shift procedure is used for a limited array of elements of the time series, which consists of parameter values. The structure of a generalized one-factor model for tracking changes in the state of an object based on an analysis of changes in Poincare diagrams is proposed. Assessment of the state of the object is based on the analysis of the spread of the points of the array on the diagram relative to the center of mass at each time point","PeriodicalId":122716,"journal":{"name":"2020 Moscow Workshop on Electronic and Networking Technologies (MWENT)","volume":"148 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134091374","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, we guess that NoC communications can find application in IoT technology, because it combine routing functions with information processing functions.","PeriodicalId":122716,"journal":{"name":"2020 Moscow Workshop on Electronic and Networking Technologies (MWENT)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125876795","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}

Turin, Ekaterina N. Pilyaeva, Igor V. Golovin","doi":"10.1109/MWENT47943.2020.9067473","DOIUrl":"https://doi.org/10.1109/MWENT47943.2020.9067473","url":null,"abstract":"Previously the problem of the heat flux distribution at the semiconductor-substrate interface in the semiconductor-substrate transistor structure with adiabatic boundary condition on top of semiconductor was solved analytically. The method of images for two cases of a point and a linear heat sources located on the top of semiconductor layer was used to solve this problem. The substrate was considered as a half-space adjacent to the bottom of the semiconductor layer unlimited on the sides. It has been shown that even in the case of a perfect heat sink into substrate, the heat flow transverse dimension at the semiconductor-substrate interface has the order of thickness of the semiconductor layer. And with decreasing thermal conductivity of the substrate, this transverse dimension increases substantially. In our work, so far only for the case of a point heat source, a solution of a more general problem of heat propagation in the passivation-semiconductor-substrate transistor structure is obtained. Using the method of images, we calculate the transverse dimension of the heat flux at the semiconductor-substrate interface depending on the value of the thermal conductivity of the substrate for different values of the thermal conductivity of passivation. According to our study, the appearance of the heat sink into passivation leads to an increase in the transverse dimension of the heat flow at the semiconductor-substrate interface, although the proportion of heat going into the substrate decreases. Our research should help to optimize the design of transistor structures taking into account the heat transfer into passivation, which is relevant, for example, for high-power transistors based on wide band gap semiconductors, such as GaN and SiC, when the heat dissipation in the active region of the device, located close to passivation, is very high. In addition, our results confirm the previously developed practical recommendation for TCAD simulations with accounting for self-heating effect.","PeriodicalId":122716,"journal":{"name":"2020 Moscow Workshop on Electronic and Networking Technologies (MWENT)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128849915","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}
