The issues of determining the actual UBI when creating MIS that process personal data using a specific technology of expert assessment are considered. The proposed methodology for determining actual threats to information security for MIS, in comparison with those used, eliminates subjective assessments that are a characteristic feature of traditional expert assessments. Its use also makes it possible to assess the relevance of information security threats for MIS that do not have qualified specialists in the field of information security in the staff of a medical institution, which is relevant for a large number of medical institutions. The authors investigate the practical possibilities of using the theory of fuzzy sets and fuzzy logic in determining the actual UBI for MIS for various purposes.","PeriodicalId":107042,"journal":{"name":"Omsk Scientific Bulletin","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130269398","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}

Modeling has shown that the presence of several closely spaced defects does not lead to an increase in the electric field intensity in comparison with one defect. On the basis of experimental studies, an analysis of defects' number influence on various parameters of partial discharges (PD) is performed. Artificial defects are created in the area of the XLPE-insulated cable termination. The following parameters of PD are measured: the magnitude of the apparent charge, the power (intensity) of partial discharges, the phase-resolved partial discharge (PRPD) patterns, the shape of PD signals. The analysis shows an increase in the number of defects does not affect the characteristics of partial discharges, despite the fact the defects are located in different sections of the cable with distributed parameters. Thus, it can be difficult to quantify defects during cable partial discharge measurements.","PeriodicalId":107042,"journal":{"name":"Omsk Scientific Bulletin","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127834043","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 study of the electronic structure of the nanocomposite, performed by X-ray photoelectron spectroscopy (XPS), showed that manganese is in two chemically nonequivalent states in MnO2-x and in KMnO4 . It has been established that manganese oxide is deficient in oxygen. In the course of electrochemical tests performed by the method of cyclic voltammetry (CVA), it is shown that the electrode based on the nanocomposite showed high arial capacitance values of 320 mF∙cm–2 at a potential scan rate of 5 mV∙s–1 and a low gravimetric capacitance of 14 F∙g–1. With an increase in the potential scan rate, the specific capacitance of the nanocomposite significantly decreased relative to CNTs, which is due to a number of reasons: (i) insufficient porosity of the electrode surface; (ii) a decrease in the amount of MnOx nanoparticles in the electrode and their dissolution in the electrolyte during charge-discharge processes.","PeriodicalId":107042,"journal":{"name":"Omsk Scientific Bulletin","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126811025","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}
