— Designing of the composite services with desired quality is an interesting challenge in web service environments. In a QoS-aware web service composition, appropriate services with acceptable quality are selected among several function-equivalent candidate services. The selection is performed in such a way that creates a composition with optimal quality(More)
A wide variety of disease outbreak detection methods has been developed in automated public health surveillance systems. The choice of outbreak detection method results in large changes in performance under different circumstances. In this paper, we investigate how outbreak detection methods can be combined in order to improve the overall detection(More)
OBJECTIVE To develop a probabilistic model for discovering and quantifying determinants of outbreak detection and to use the model to predict detection performance for new outbreaks. MATERIALS AND METHODS We used an existing software platform to simulate waterborne disease outbreaks of varying duration and magnitude. The simulated data were overlaid on(More)
