Planned Disconnections for Mobile Databases
As mobility permeates todays computing environment, we envision application infrastructures that will increasingly use mobile technologies. Traditional database applications will need to integrate mobile entities: people and computers. In this paper, we develop a distributed database framework for mobile environments. A key requirement in such an environment is to support frequent connection an...
متن کاملExploiting Planned Disconnections in Mobile Environments
We present the notion of a distributed database made up entirely of mobile components. Since disconnections will be frequent in such an environment, we develop a disconnection and reconnection procedure to allow normal processing on the connected components. We briefly discuss a protocol based on epidemic communication to support such a system while ensuring one-copy serializability.

متن کاملDistortions and disconnections: disrupted brain connectivity in autism.
The past few years have seen considerable interest in findings of abnormal brain connectivity in the autism spectrum disorders (ASD). We review recent work from neuroimaging and other sources, and argue that there is considerable convergent evidence suggesting that connectivity is disrupted in ASD. We point to evidence both of local over-connectivity and of long-distance under-connectivity, and...
متن کاملPublic health: disconnections between policy, practice and research
BACKGROUND Public health includes policy, practice and research but to sufficiently connect academic research, practice and public health policy appears to be difficult. Collaboration between policy, practice and research is imperative to obtaining more solid evidence in public health. However, the three domains do not easily work together because they emanate from three more or less independen...
