Context dependent systems are granted thanks to the convergence of several technologies as wireless communications, Internet, geographic information systems, etc. The aim of this paper is not to analyse the optimal technical solution to this problem, but to understand the importance and perceived value for users of having this kind of services or applications in their mobile devices. In most of...

One of the main issues in mobile services’ research (M-service) is supporting M-service availability, regardless of the user’s context (physical location, device employed, etc.). However, most scenarios also require the enforcement of context-awareness, to dynamically adapt M-services depending on the context in which they are requested. In this paper, we focus on the problem of adapting M-serv...

The spectrum access rights granted by the Federal government to spectrum users come with the expectation of protection from harmful interference. As a consequence of the growth of wireless demand and services of all types, technical progress enabling smart agile radio networks, and on-going spectrum management reform, there is both a need and opportunity to use and share spectrum more intensive...

Previously, it has been argued that health information efforts need to inform the public about meaningful differential risks from tobacco/nicotine products. The fact of multiple product use by the same individual further supports this need. When the majority of youth, for example, who use smokeless tobacco are also current tobacco smokers, it makes little sense to mount a smokeless prevention c...

The most important challenge for the global energy sector is to rapidly transform entire system one less dependent on fossil fuels and so reduce harmful effects climate [...]
