In these systems, the number of users is significantly increased in relation to local systems, and the fact is that the public network is very frequently used for data transfer. As medical data are very sensitive, such situation creates considerable risk regarding privacy, integrity and right to access to these data. This paper includes the most frequent risks and methods to solve these issues as well as recommendations for safe use of cloud computing systems in order to implement these systems.","PeriodicalId":187159,"journal":{"name":"JITA - Journal of Information Technology and Applications (Banja Luka) - APEIRON","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131999850","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}

Using the spectral method of determining the period of the survey, you can choose different value depending on the category of the train and its dynamic characteristics. For high-speed trains, the period of sensors is less than for trucks, since the latter are tightened by the transients during acceleration and deceleration.","PeriodicalId":187159,"journal":{"name":"JITA - Journal of Information Technology and Applications (Banja Luka) - APEIRON","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130474153","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}

Actually, there is no central point of coordination; each node is responsible for forwarding data packets to other nodes, thereby acting as router and host. A packet might travel through multiple intermediary ad hoc nodes in order to arrive to its destination, while the nature of wireless multi-hop channel is bringing in various types of packet losses. This paper focuses on three main reasons of online packet losses in MANETs: (1) losses due to wireless link errors; (2) losses due to congestion; and (3) losses due to route alteration. It proposes a deep learning-based algorithm for packet loss discrimination. The algorithm uses the backpropagation neural network (BPNN) concept. We performed simulation experiments for evaluating the performance of the proposed loss discrimination algorithm under different network configurations. Through simulation results, we confirmed that the proposed algorithm improves packet loss discrimination and route alteration in the network. It also reduces congestion and increases network throughput.","PeriodicalId":187159,"journal":{"name":"JITA - Journal of Information Technology and Applications (Banja Luka) - APEIRON","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124945324","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 Services Directive unifies the services market throughout the European Union and creates an obligation for each Member State to improve its way of providing services to citizens. Citizens are accessing services through digital identities.Having in mind that Bosnia and Herzegovina have for more than 65% turnover with EU countries, there is a need and legal obligation for the introduction of the same standards in the field of digital services and digital identities in BiH as in the EU. Citizens and businesses in Bosnia and Herzegovina need to have same position with competitive and compatible markets in EU countries. To validate digital identities, it is possible to use ID documents in BiH. This paper described the way of validating the digital identity in BiH using ID card or passport. ID documents issued according to ICAO 9303 standards and EU regulations must have embedded chips. These documents can be used to access electronic services as well as for digital identity verification.","PeriodicalId":187159,"journal":{"name":"JITA - Journal of Information Technology and Applications (Banja Luka) - APEIRON","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115546190","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}
