For this purpose we make use of a graph of waypoints, which is based on GPS coordinates of flight path maneuver points in the threedimensional space. The graph is represented by a dynamic adjacency matrix, on which we carry out a comparative evaluation of the predicted drone route. We assess the advantages and disadvantages of the two routing algorithms in the context of area observation mode “go round the area\".","PeriodicalId":374877,"journal":{"name":"2018 IEEE XXVII International Scientific Conference Electronics - ET","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134520108","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 corresponds to physical based approximations with approbated quantity effectiveness. The method has been used to study the influence of atmospheric turbulence on BER of FSO. Following this method an algorithm for FSO power design, based on the random laser beam shift, caused by random character of the Atmospheric turbulence has been made. Numerical examples, illustrated by graphic material, have been shown.","PeriodicalId":374877,"journal":{"name":"2018 IEEE XXVII International Scientific Conference Electronics - ET","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123623331","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 first two steps aim to select a person-independent subset of attributes that are repeatedly selected for a large population of users. Next, this selection is intersect with a person-specific subset derived from the Fisher's separation criterion. As a result, we obtain a subset of attributes which is both task-specific and customized to the quality of data of each particular user. The proposed method was validated on the ASCERTAIN database in an experimental setup oriented towards high-arousal negative-valence detection based on physiological signals. The experimental results support that the proposed method offers advantage in terms of detection accuracy when compared to other subset selection strategies.","PeriodicalId":374877,"journal":{"name":"2018 IEEE XXVII International Scientific Conference Electronics - ET","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126138770","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}
