OBJECTIVE: Physiological track-and-trigger warning systems are used to identify patients on acute wards at risk of deterioration, as early as possible. The... CP Subbe,H Gao,DA Harrison - 《Intensive Care Medicine》 被引量: 286发表: 2007年 加载更多来源...
Effective monitoring and early warning systems are needed to be able to forecast sinkhole collapses and thus reduce the risk for people and property. The main issue is related to the quick identification of deformational anomalies, which are generally very small with respect to the sinkhole-prone ...
Detecting early-warning signals of critical transitions for complex systems Considerable evidence suggests that during the progression of complex diseases, the deteriorations are not necessarily smooth but are abrupt, and may cause a critical transition from one state to another at a tipping point. ...
Early warning scores are frequently used in UK adult emergency departments (EDs) and are gaining traction in paediatric emergency care. Like many innovations with inherent face validity, they have great appeal to clinicians, managers and commissioners. However, it is important to ensure unintended con...
monitoring to identify how risks evolve through time; – response capability; – warning communication which packages the monitoring information into actionable messages understood by those that need, and are prepared, to hear them. This includes, on the one hand, the gathering, processing and presen...
In this study, we identify early warning signals such as increase in variance and conditional heteroskedasticity close to a subcritical Hopf bifurcation. We find that these measures are robust even when the system under consideration is under the influence of external noise. Many physical systems unde...
Here, we summarize a range of currently available early warning methods and apply them to two simulated time series that are typical of systems undergoing a critical transition. In addition to a methodological guide, our work offers a practical toolbox that may be used in a wide range of ...
The designs also included the development of detailed response plans that are used for making decisions during a developing condition, including when failure of the dam is imminent and the evacuation should be initiated. Both early warning systems include a notification component that consists of a ...
3.1. Warning and dissemination for epidemic and pandemic Effective early warning systems are comprised of four interconnected elements: (1) disaster risk knowledge based on the systematic collection of data and disaster risk assessments; (2) detection, monitoring, analysis and forecasting of the hazards...
Early warning signs, indicating directly or indirectly the presence of causal factors to losses within a system or in its environment do exist and precede losses. For example, Sonnemans and Körvers (2006) studied accidents that occurred in the chemical industry to identify signs which indicate...
