Based on the complexity of hyperchaotic dynamical systems and unpredictability of hidden attractors, which may exist in their phase spaces and could be beneficial in secure communications, a scheme to derive the analytical formula of the control functions is stated to study active control synchronization. Further comparison of this analytical formula with numerical experiments yields an interesting agreement. A novel fractional-order complex Sprott system is proposed to study this kind of synchronization and its dynamics. A secure communication scheme based on the active control synchronization of hyperchaotic fractional-order complex Sprott system is presented. Two types of masked messages (plain text and audio signal) are considered as test examples.","PeriodicalId":447345,"journal":{"name":"2021 IEEE Conference of Russian Young Researchers in Electrical and Electronic Engineering (ElConRus)","volume":"226 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120976768","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 analysis, sections of pipelines of the heat networks of the city of Voronezh were selected that have different conditions and modes of operation. Based on the statistical analysis of the data, factors affecting the operational reliability of each section of the pipelines under investigation were selected. At the first stage, the systematization and unification of the selected factors was carried out, and, in order to identify groups of pipeline sections with the most similar operational parameters, they were divided into classes. The division into classes was implemented by cluster analysis methods. At the next stage, one of the agglomerative methods of hierarchical cluster analysis was chosen, the Ward method, which allows achieving the minimum variance within a class of factors with homogeneous properties. The achieved results make it possible to determine the factors that have a significant impact on the operational reliability of pipeline sections of engineering networks, as well as to identify areas with a fairly high level of pipeline failures","PeriodicalId":447345,"journal":{"name":"2021 IEEE Conference of Russian Young Researchers in Electrical and Electronic Engineering (ElConRus)","volume":"33 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":"127321258","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}
