This is a special challenge for any specialist in the domain both due to the particularly high density of technical means that are available on board military ships, and the fact that radio communication systems can be both sources of disturbance and victims. In obtaining the EMC of the systems, the inter and intrasystem disturbances must be identified and analysed. In order to fulfil the missions of combat, search and rescue and more recently, maritime surveillance and interception of boats with emigrants or refugees, military ships are constituted in naval groups. Such a group often includes ships under different flags, which are equipped with equipment and equipment from different suppliers and from different generations. In this sense, the entire naval grouping must be considered as a system, and the success of the mission may depend on the EMC's provision of the entire system.In the present paper, the authors present an algorithm for calculating the interference margins, necessary to obtain the EMC of a communications system related to a naval grouping starting from the basic EMC equation. The authors develop the EMC equation for radio communication systems aboard military ships.","PeriodicalId":145923,"journal":{"name":"2020 International Symposium on Fundamentals of Electrical Engineering (ISFEE)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126572886","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 identification and signaling of cyber-attacks allows maintaining control over the system and has thus become a topical issue. The purpose of this work is to create an intrusion warning system capable of signaling the system administrator, which is not normally the case. At the same time, part of the goal was to write our own conditions under which the system considers itself attacked. We have created an application capable of communicating with the server and creating a list of all alarms triggered. This work manages to combine a large number of platforms, programming languages and tools, some of them atypical. We believe that we have thus achieved the goal of creating a tool to protect a system in which communications and activities can take place safely.","PeriodicalId":145923,"journal":{"name":"2020 International Symposium on Fundamentals of Electrical Engineering (ISFEE)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134491243","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 salt crystallization from saliva forms a certain pattern called ferning which can determine the level of estrogen. There are three important stages: no ferning, partial ferning and full ferning. The proposed system intends to automatically determine the fertile period in a cheap, easy, and precise way. The proposed system includes a hardware part, making a miniaturized microscopic device with high performance for image acquisition, and a software able to analyze the images and displaying real-time results based on human saliva samples. For the image processing part, we propose two approaches. The first approach implies the use of the Bag of Words concept, were the words are patches with different ferning styles. For words description we use: CLAHE for image enhancement, Otsu and Frangi filter for ferning emphasis, Local Binary Pattern (LBP) for feature representation of words. For final classification, a support vector machine (SVM) was used, and we classify the frequency of words in one image (the histogram of words). The second image processing approach uses a convolutional neuronal network (CNN). The experimental results show that the proposed system can be used to classify the ferning stage in salivary images, with an accuracy of 0.96 using the SVM classification.","PeriodicalId":145923,"journal":{"name":"2020 International Symposium on Fundamentals of Electrical Engineering (ISFEE)","volume":"10 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120979926","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}
