Deposition was carried out at room temperature, the thickness of the films was 500 nm. The resistivity, Seebeck coefficient and thermal conductivity of thin films were measured. The resistivity of as-deposited layers was about 3500 Ohm·cm and dropped sharply after annealing at a temperature of 260°C for 30 minutes, which is due to the phase transition of the material. The Seebeck coefficient for the as-deposited films was about 1000 μV/K, and the thermal conductivity was 0.16 W/(m·K).

Analyzing these combinations requires capabilities beyond the traditional database management systems' abilities. Among most sources of big data appears e-markets and social media platforms as significant contributors. This distinction is due to its features that facilitate consumers to express their views or opinions about specific products and services. Customer reviews and ratings become a significant resource for both consumers and firms regarding their plentiful and valuable knowledge. The proposed work introduces a big data framework to analyze such reviews and ratings, starting with data collection from different sources. Followed by integrating the collected data, which comes in different formats, toward the further processing phase. Finally, the analysis and visualization steps to draw the conclusions. Our work was tested on real data collected from active web resources.","PeriodicalId":447345,"journal":{"name":"2021 IEEE Conference of Russian Young Researchers in Electrical and Electronic Engineering (ElConRus)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127814845","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}

Electrically conductive carbon nanotubes networks in non-conductive polymer matrix were obtained, high electrical conductivity of the material (∼0.1 S/m) was achieved. Network architecture was built using pulsed ytterbium laser, operating at wavelength 1064 nm.

The objective of this work is to experimentally determine the mechanical stresses and mechanical strength of SiO2 thin-film membranes obtained by the layer-by-layer deposition. To achieve this goal, we used analytical equipment (ellipsometer, SEM, optical profiler), computing equipment (calculations in MATLAB), and technological (system for the deposition of thin films). The mechanical strength of SiO2 is experimentally determined by the bulge method. The value of mechanical stresses varies from 188 to 26.7 MPa with an increasing thickness of SiO2 from 226 to 2017 nm. The determined value of the mechanical strength of silicon oxide is 1.84 GPa for a thickness of 1.5 microns and 1.27 GPa for a thickness of 2 microns. The layer-by-layer deposition of a thin film of silicon oxide by the PECVD method can reduce the value of mechanical stresses. The measured values of mechanical strength correlate well with the results of other studies.","PeriodicalId":447345,"journal":{"name":"2021 IEEE Conference of Russian Young Researchers in Electrical and Electronic Engineering (ElConRus)","volume":"205 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123049677","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}

The basic principle of operation of Data Measuring Systems with adaptive sampling is based on the fact that the sampling frequency of input signals is not constant for a specific system, but changes in accordance with changes in certain parameters of input signals. In this case, the number of signal samples is reduced while maintaining the specified approximation error. The measured value is approximated by some function, usually called the basic one. Comparison of this functions is carried out in accordance with the accepted fidelity criterion. At the moments of time when the difference between functions - the approximation error - reaches a given allowable value, the input signal count is considered significant and is used for further processing, transmission, indication or registration.","PeriodicalId":447345,"journal":{"name":"2021 IEEE Conference of Russian Young Researchers in Electrical and Electronic Engineering (ElConRus)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114161003","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}
