Mobile devices are increasingly being used in the workplace. The combination of touch, pen, and speech interaction with mobile devices is considered particularly promising for a more natural experience. However, we do not yet know how everyday work with multimodal data visualizations on a mobile device differs from working in the standard WIMP workplace setup. To address this gap, we created a visualization...
Digital Identity has grown separately in the IP Multimedia Subsystem (IMS) and the Internet in general. On the one hand secure but walled garden services are offered on the other hand the focus is on openness and third party integration. However, future Telco-business needs an inter-working of IMS and Internet. This paper discusses use cases, economical benefits and technical solutions for bridging...
OASIS XACML has become a recognized standard for the specification of access control policies, and has specified a generic framework for access control. While the XACML policy language is very flexible for access privileges, there is currently no method to specify the obligations send from a policy decision point (PDP) to a policy enforcement point (PEP) in a generic way. Potential conflicts between...
In recent years, Identity Management (IdM) has gained a lot of attention in industry, standardisation and academia. In particular, a couple of research projects, like Daidalos or Prime, have invested considerable effort to bring IdM forward, to take advantage of features like improved usability and security. Nevertheless, there are important issues that have not been addressed so far. The SWIFT project...
Personalization of service delivery is an important means for the telecommunication industry of keeping their customers in spite of their market becoming more open to other players. Personalization involves using user-specific, dynamic information about communication activities, device capabilities, user context, and service availability for making real-time decisions about handling running sessions...
The success of future NGN services depends on the ability to adapt and personalize service delivery according to the user's context as well as service and device capabilities. Personalization includes not only respecting explicit user preferences, but also offering optimized multi-device communication. Flexible handling of multiple devices as well as multiple sessions is an increasing demand in the...
The creation of new service revenue streams supported by consistent user experiences is one of the topics for the future service layer. Personalization over real-time decision enablement is one important option to explore for new business models. The paper introduces a novel personalization communication control mechanism across services, devices and platforms realizing realtime decision enablement...
Lanthanum hexaaluminate (LHA) with a magnetoplumbite structure is a promising competitor to yttria partially stabilized zirconia (Y-PSZ) as a thermal barrier coating (TBC), since most zirconia coatings age significantly, including undesired densification at temperatures exceeding 1100 o C. The microstructure of calcined lanthanum hexaaluminate powders and thermally sprayed coatings show a...
