Data with high security requirements is being processed and stored with increasing frequency in the Cloud. To guarantee that the data is being dealt in a secure manner we investigate the applicability of Assurance methodologies. In a typical Cloud environment the setup of multiple layers and different stakeholders determines security properties of individual components that are used to compose Cloud applications. We present a methodology adapted from Common Criteria for aggregating information reflecting the security properties of individual constituent components of Cloud applications. This aggregated information is used to categorise overall application security in terms of Assurance Levels and to provide a continuous assurance level evaluation. It gives the service owner an overview of the security of his service, without requiring detailed manual analyses of log files.

Senior tourists and handicapped tourists constitute a growing market as the European Population is ageing continuously (Alén et al. 2012). Between mid-2012 and mid-2013, these two segments accounted for 783 million trips of one or several days' duration within the European Union (Neumannconsult 2014). Although the potential of increased revenues from "accessible tourism" has been widely recognised and supported in several studies at a European level, touristic providers have as yet largely failed to react with the necessary adaptations of their existing offers. In this presentation, an exploratory study of handicapped tourists‘ experiences is presented. A multi-method approach is used to analyse the service scape of an Austrian Spa, a festival organizer, and a museum, from the tourists’ point of view. The results give an insight into different types of impairment. Best practice examples are compared with typical shortcomings in the service scape of these tourism providers.

We present an experimental evaluation of energy usage and performance in a wireless LAN cell based on a test bed using the 5 GHz ISM band for 802.11a and 802.11n. We have taken an application-level approach, by varying the packet size and transmission rate at the protocol level and evaluating energy usage across a range of application transmission rates using both large and small packet sizes. We have observed that both the application's transmission rate and the packet size have an impact on energy efficiency for transmission in our test bed. We also included in our experiments evaluation of the energy efficiency of emulations of YouTube and Skype flows, and a comparison with Ethernet transmissions.
