For safety-critical applications, employing a multiphase machine generally enhances system reliability, however, a multiphase converter and transformer will be then needed. This paper proposes a simple drive system using a four-switch based five-phase drive system for motors fed through long cables. The system simply comprises a four-switch converter, which is controlled to produce a balanced two-phase output, and a static transformer that converts the two-phase inverter output voltage to five-phase balanced voltages. The proposed system is simulated using MATLAB/SIMULINK to verify the proposed concept.","PeriodicalId":412517,"journal":{"name":"2016 IEEE Symposium on Computer Applications & Industrial Electronics (ISCAIE)","volume":"125 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122698590","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 level of Fault Current (FC) could even exceed the ratings of the existing power system infrastructure, causing damage to the system components. Thus, a need exists to limit the FC levels. This paper is surveying different types of fault current limiters (FCLs), especially the solid state-based types shedding light on the design of a controllable single phase full bridge inverter type for low voltage distribution systems. Impedance and voltage-based approaches are proposed for controlling the FC levels. Simulation and experimental results are presented to elucidate the claimed contribution.","PeriodicalId":412517,"journal":{"name":"2016 IEEE Symposium on Computer Applications & Industrial Electronics (ISCAIE)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133598876","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}

On the other hand, the mobile devices are less protected in comparison to computers. Therefore, the mobile devices and networks have now become attractive targets for attackers. Amongst several types of mobile threats, the mobile HTTP Botnets can be considered as one of the most sophisticated attacks. A HTTP Bots stealthily infect mobile devices and periodically communicate with their controller called Botmaster. Although the Bots hide their activities amongst the normal web flows, their periodic pattern has been used as a measure to detect their activities. In this paper we propose a cooperative network behaviour analysis model to identify the level of periodicity posed by mobile Bots. Finally three metrics is proposed to detect Mobile HTTP Botnets based on similarity and correlation of their group activities. Test results show that the propose model can efficiently classify communication patterns into several periodicity categories and detect mobile Botnets.","PeriodicalId":412517,"journal":{"name":"2016 IEEE Symposium on Computer Applications & Industrial Electronics (ISCAIE)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128364592","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}
