In a real-time database system, it is difficult to meet all timing constraints due to the consistency requirements of the underlying database. Real-time database transaction scheduling requires the development of efficient concurrency control protocols that try to maximize the number of transactions satisfying their real-time constraints. Therefore transaction priorities should be taken account...

Flow control is the dominant technique currently used in communication networks for preventing excess traffic from flooding the network, and for handling congestion. In ratebased flow control, transmission rates of sessions are adjusted in an end-to-end manner through a sequence of operations. In this work, we present a theory of max-min fair, ratebased flow control sensitive to priorities of d...

Comprehensive animal health surveillance programmes require components that ensure the overall sensitivity and timeliness of surveillance data. Participatory epidemiology (PE) is the application of participatory rural appraisal techniques to the collection of epidemiological intelligence. Participatory disease searching (PDS) is the use of PE techniques in active disease surveillance and outbre...
