In emerging ubiquitous computing, related nomadic users often perform similar tasks and share the same computing infrastructure. This means that security of the shared resources is of prime importance. Frequent delegation of tasks among users must be anticipated as most nomadic environments are hectic and very dynamic. A delegation mechanism with a slightly complicated user interface will not o...

We investigated the relationship between a 2000-year history of nomadic migration and climate change in historical China. By using updated data and statistical methods, the study solved several unanswered questions from past research about the relationship between climate change and the nomadic migration, especially over the long term and on a large spatial scale. The study used correlation ana...

Our goal is to de ne a communication architecture for nomadic applications. We notice that the mobile agent paradigm is particularly suitable for nomadic applications. Although many mobile agent systems are being proposed, few of them raise the problem of the interface between applications and mobile agents. We propose to use the MAP (Mobile Assistant Programming) architecture and add a middlew...

The possibility to uniformly access the WWW using a standard web browser has fostered the development of nomadic desktop computing, allowing nomadic users to run their applications from nearly any location providing access to the Internet. In this paper, we propose an approach to nomadic desktop computing based on the idea of dynamically deploying and executing personalized applications on the ...

The paper describes a nomadic information system under development by GMD in the HIPS project that supports nomadic activities adapted to the individual visitor of a museum. The world-wide Web, wired and wireless connectivity to networks, and small mobile devices allow for supporting nomadic activities by information and communication technology to an extensive degree. Mobile information techno...
