The entire transaction is executed online, but also in a secure way, ensuring the real identity of both the buyer and the seller. Users will benefit from various offers with a good value for money. Firstly, they will be able to follow the booking steps in a simple way, ideal for inexperienced users, with instructions and warning messages. Secondly, it is no secret that today's people are busy, the lack of time is more and more accentuated, and the online environment has gained ground in their lives. Along with online transactions, human or system errors have appeared, users being often put in unpleasant situations. One solution to this problem is the token device - a device with a special structure that incorporates cryptographic algorithms (symmetric and asymmetric) that allow the safe performance of cryptographic operations. In the application presented in this paper, both users and sellers digitally sign holiday booking documents, thus managing to provide beneficiaries with a strong reason to confirm that the digital document is created by the person who signed it, and the content of the digital document has not been modified since its date of issue.","PeriodicalId":145923,"journal":{"name":"2020 International Symposium on Fundamentals of Electrical Engineering (ISFEE)","volume":"PP 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":"126423689","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}

Their penetration degree and characteristics of the injected active power must be known as good as possible to evaluate the effects on the operation of the ADNs. Based on these considerations, a data mining-based methodology is proposed to identify the real behavioural characteristics of prosumers, represented by the injected active power typical profiles (IAPTPs), within the ADNs. Inside the methodology, the K-means clustering method was used to obtain the IAPTPs of the prosumers. The testing was done using a database with 64 prosumers, having PV systems installed, that inject the active power in the LV electric distribution networks of the DNO from the north-eastern region of Romania. The proposed methodology represents an efficient solution to identify easy and quickly the real behavioural characteristics of the prosumers, helping the DNOs to evaluate the impact on the operation of the ADNs.","PeriodicalId":145923,"journal":{"name":"2020 International Symposium on Fundamentals of Electrical Engineering (ISFEE)","volume":"58 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":"126491825","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}

They currently have a wide range of applicability covering various fields from medicine to aerospace construction, from sports equipment to boats, from architectural constructions to cars, etc. Due to their use on such a large and diverse scale, it is important to study and analyse their behaviour in various situations and environmental conditions. This paper aims the experimental study of the fire behaviour of four composite materials (High Impact Polystyrene (HIPS), Cellular Polypropylene, Compact Polycarbonate and Polypropylene Copolymer (PP-C)) used for various applications in interior or exterior architectural constructions. The experimental determinations, performed on specimens located horizontally or vertically against the standardized flame with a power of 50W, were performed according to IEC 60695-11-10: 2013, in the fire risk testing laboratory of the National Institute for Research and Development and Testing in Electrical Engineering - ICMET Craiova. The experimental results showed that out of the four materials studied, only the Polycarbonate specimens behaved well and could meet the standardized classification criteria.","PeriodicalId":145923,"journal":{"name":"2020 International Symposium on Fundamentals of Electrical Engineering (ISFEE)","volume":"36 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":"134108978","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}

Thus, on a ship we can frequently meet electrical and electronic equipment from several generations and from several manufacturers, equipment that has been designed based on different standards. Moreover, due to cost issues, the general trend is to purchase off-the-shelf (COTS) equipment that has not been designed to naval military standards. This requires a thorough analysis of the electromagnetic environment in which the new equipment will operate and compliance with all rules and principles of electromagnetic compatibility during their installation and operation.In this paper the authors make an analysis of trends in the construction and modernization of military ships and propose a way to calculate the magnetic field of dispersal disturbance at a point inside a space / volume in order to assess the electromagnetic environment and establish appropriate antiperturbation measures when introducing a new electrical or electronic equipment in the analyzed space / place.","PeriodicalId":145923,"journal":{"name":"2020 International Symposium on Fundamentals of Electrical Engineering (ISFEE)","volume":"23 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":"115686329","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}
