The lack of security has been the main concern. Organizations and entities need to ensure, inter alia, the integrity and confidentiality of their outsourced sensible data within a cloud provider server. Solutions have been examined in order to strengthen security models (strong authentication, encryption and fragmentation before storing, access control policies…). More particularly, data remanence is undoubtedly a major threat. How could we be sure that data are, when is requested, truly and appropriately deleted from remote servers? In this paper, we aim to produce a survey about this interesting subject and to address the problem of residual data in a cloud-computing environment, which is characterized by the use of virtual machines instantiated in remote servers owned by a third party.","PeriodicalId":147797,"journal":{"name":"2017 International Conference on Wireless Technologies, Embedded and Intelligent Systems (WITS)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134538846","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 system includes a wind turbine, a five-phase Permanent Magnet Generator, two converters, an RL filter, and a DC-link capacitor. The machine side converter is controlled by using the Field Oriented Control, to drive the generator speed to its optimum value. However, The control algorithm of grid side is based on Voltage Oriented Control to inject a pure active power into the grid. The efficiency of considered wind energy system has been studied and simulated by using MATLAB/Simulink environment.","PeriodicalId":147797,"journal":{"name":"2017 International Conference on Wireless Technologies, Embedded and Intelligent Systems (WITS)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127639614","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 etched DGS topologies on the ground plane as well as its coupling provide the slow-wave characteristics [1, 2. In order to control the operate frequency range of the filter and its results, the Chebyshev's rule, suspended Layer's technique first order and logarithmic method are employed. The proposed filters are partially measured, simulated, optimized and compared. The lowpass filters designed at cutoff frequency of 2.0GHz/3GHz/4.5GHz, which are suitable for GSM900, radar and wireless local area network applications. The proposed filters have low insertion loss, high return loss in the passband and wide stopband as well as very sharp roll-off characteristics for near pass-band. The proposed topologies are designed, optimized and simulated on RO4003 substrate using AWR software. The measurements show good consistency with the simulations. The minor discrepancy between both results can be attributed to the unexpected tolerance of the manufacturing process and reflections from the SMA connectors.","PeriodicalId":147797,"journal":{"name":"2017 International Conference on Wireless Technologies, Embedded and Intelligent Systems (WITS)","volume":"128 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132544941","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}
