Although digital appliances are designed to be easy to use, their users often cannot even perform simple tasks because the devices lack infrastructural support. The Appliance Data Services project seeks to explore the attributes of an appliance computing world and develop the infrastructure required to support users with digital appliances.

Background Populous developing nations like India have a huge disease burden of CHD, many of the patients being older, with uncorrected or partially palliated complex lesions. Despite its powerful diagnostic advantages in this specific clinical milieu, cardiac MRI is yet to find widespread acceptance, the reasons being poor awareness regarding CMR and its clinical utility, infrastructural costs...

Three kinds of selection are reviewed with primary focus on the relations between behavioral and cultural contingencies. Operant behavior is briefly examined with regard to cultural materialist theory. The functions of verbal behavior in infrastructural and superstructural practices are suggested. Discrepancies between rules promulgated in the superstructure and the requirements of the infrastr...

Pedestrians are highly heterogeneous with regards to their physical capabilities and preferences, which in turn determine their individual infrastructural needs (Saelens et al. 2003, Millonig 2006). Other than in current pedestrian navigation systems, therefore, the possibility to compute personalized walking routes would be desirable, a precondition of which, however, is to derive detailed use...

This paper introduces a new architecture that aims at combining molecular biology data with information automatically extracted from relevant scientific literature (using text mining techniques on PubMed abstracts and fulltext papers) to help biomedical experts to interpret experimental results in hand. The infrastructural level bears on semantic-web technologies and standards that facilitate t...

Several routing algorithms for mobile ad hoc networks have been proposed in the recent past [Broch et al., The Dynamic Source Routing Protocol for Mobile Ad Hoc Networks, Internet Draft draft-ietf-manet-dsr-03.txt, October 1999; Perkins et al., Ad Hoc On Demand Distance Vector (AODV) Routing, Internet Draft draft-ietf-manet-aodv04.txt, October 1999; Haas and Pearlman, The Zone Routing Protocol ...

HTTP is a successful Internet technology on top of which a lot of the web resides. However, limitations with its current specification, i.e. HTTP/1.1, have encouraged some to look for the next generation of HTTP. In SPDY, Google has come up with such a proposal that has growing community acceptance, especially after being adopted by the IETF HTTPbis-WG as the basis for HTTP/2.0. SPDY has the po...

Video games have enormous mass appeal, reaching audiences in the hundreds of thousands to millions. They also embed many pedagogical practices known to be effective in other environments. This article reviews the sparse but encouraging data on learning outcomes for video games in science, technology, engineering, and math (STEM) disciplines, then reviews the infrastructural obstacles to wider a...

The increasing deployment of mobile devices and accompanying services leads to new security challenges. Due to the changed premises caused by particular features of mobile systems, these obstacles cannot be solved solely by traditional security paradigms and mechanisms. Drawing on the example of wireless LANs, this thesis examines the development of security mechanisms for wireless ad hoc and i...

BACKGROUND This article conducts a comparative national and subnational government analysis of the political, economic, and ideational constructivist contextual factors facilitating the adoption of obesity and diabetes policy. METHODS We adopt a nested analytical approach to policy analysis, which combines cross-national statistical analysis with subnational case study comparisons to examine ...
