We discuss specific spatial data related to countries and analyse them in relationship to number of attempted attacks collected by honeypots. In the paper, we analyse the relationship between the spatial data and number of attempted attacks and properties of countries, from which attackers attack. We found that there is relationship between the spatial data related to countries and number of attempted attacks. Also the number of attacks is related to active population who use the Internet and level of infrastructure and service provision of country.","PeriodicalId":122809,"journal":{"name":"2016 8th International Conference on Electronics, Computers and Artificial Intelligence (ECAI)","volume":"19 20","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134364006","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}

Mobile cloud computing maps cloud computing ideas on top of the mobile environment, and overcomes obstacles that deal with performance (i.e. battery life, CPU, storage, and bandwidth), environment (i.e. heterogeneity, scalability, availability) and security (i.e. reliability, privacy) discussed in mobile computing. In this position paper we are going to focus in depth on a Hadoop based framework for ad-hoc mobile cloud computing — we specifically refer to a research paper and the authors' decision to use and port Hadoop to build a Virtual Cloud Computing Provider for Mobile Devices. In the beginning, we are going to outline a short introduction and enumerate the challenges that we face implementing a framework for mobile cloud computing.

The power converters consist in adapting the source of energy to the needs for the load. In this paper, we present the study of voltage oriented control with space vector modulation (VOC-SVM) strategies for three-phase PWM rectifiers. This strategy of control founded on the transformation between stationary coordinates α-β and synchronous rotating coordinates d-q, it is based on the input-output feedback linearization controller for which the objective is to control the grid current's d- and q-axis component, while the dc-bus voltage is maintained at the desired level and satisfy the unity power factor (UPF) operation. The strategy VOC-SVM ensures high static performance and fast transient response by using internal current control loop.

Because the process has a strong nonlinearity it was modeled using different linear models for different operating ranges so that the IMC controller can use the adequate model parameter values according to the current operating range. The results obtained using the multi-model standard IMC algorithm are compared with the ones obtained using the conventional PID (Proportional-Integral-Derivative) algorithm tuned using the same model parameter values used for designing the IMC controller. The simulations showed that using the proposed multi-model standard IMC algorithm is a feasible alternative for controlling this kind of process with a high nonlinear behavior, obtaining good static and dynamic performance.","PeriodicalId":122809,"journal":{"name":"2016 8th International Conference on Electronics, Computers and Artificial Intelligence (ECAI)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125582691","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}
