However, both of the methods have merits as well as drawbacks. In this paper we use the super efficiency of DEA (SEDEA) model and SFA to estimate the energy productive efficiency of 30 administrative regions of mainland China during the period 1998–2009. The comparative study of the two methods shows that despite the estimated values being quite different, the ranks of these two results are very similar. In addition, the results of the two methods suggest that energy efficiency in the eastern region of China possesses an advantage over the western regions. Further analysis indicates that SEDEA not only has the advantages of DEA and SFA, but also has the advantage of evaluation energy efficiency effectively. In addition, this paper decomposes the Malmquist index so as to explore energy efficiency comprehensively and dynamically.</p></div>","PeriodicalId":49872,"journal":{"name":"Mathematical and Computer Modelling","volume":"58 5","pages":"Pages 1000-1009"},"PeriodicalIF":0.0,"publicationDate":"2013-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.mcm.2012.09.020","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79789447","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Authorization frameworks like RBAC and ABAC do not provide scalable, manageable, effective, and efficient mechanisms to support distributed systems with many interacting services and are not able to effectively support the dynamicity and scaling needs of IoT contexts that envisage a potentially unbound number of sensors, actuators and related resources, services and subjects, as well as a more relevance of short-lived, unplanned and dynamic interaction patterns. Furthermore, as more end-users start using smart devices (e.g. smart phones, smart home appliances, etc.) the need to have more scalable, manageable, understandable and easy to use access control mechanisms increases. This paper describes a capability based access control system that enterprises, or even individuals, can use to manage their own access control processes to services and information. The proposed mechanism supports rights delegation and a more sophisticated access control customization. The proposed approach is being developed within the European FP7 IoT@Work project to manage access control to some of the project’s services deployed in the shop floor.</p></div>","PeriodicalId":49872,"journal":{"name":"Mathematical and Computer Modelling","volume":"58 5","pages":"Pages 1189-1205"},"PeriodicalIF":0.0,"publicationDate":"2013-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.mcm.2013.02.006","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89068477","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We analyze the factors that influence the environmental efficiency of Beijing using a two-step method. In the first step, a DEA model is used to assess the environmental efficiency of Beijing. In the second step, the efficiency from the first step is used as a dependent variable and factors that impact the environmental efficiency are used as independent variables. The regression model and the coefficients of the independent variables determine which factors influence the environmental efficiency and the strength of the influence. Finally, we interpret the enlightenment to the reality and the future development based on its results. The conclusion shows that the environmental efficiency of Beijing over 2005–2009 has been rising. From 2005 to 2007, the environmental efficiency of Beijing continued to increase. In 2008, the environmental efficiency reached a maximum. In 2009, Beijing maintained a high environmental efficiency. The proportion of the tertiary industry to the whole industries is the most important factor that impacts Beijing’s environmental efficiency, that is, Beijing’s industrial structure has the most influence on the city’s environmental efficiency.</p></div>","PeriodicalId":49872,"journal":{"name":"Mathematical and Computer Modelling","volume":"58 5","pages":"Pages 956-960"},"PeriodicalIF":0.0,"publicationDate":"2013-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.mcm.2012.10.016","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79420308","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
