Many complex systems undergo critical transitions. A thermoacoustic system is one such which exhibits a catastrophic transition to state of oscillatory instability known as instability. So far, several early warning signals have been devised detect the from stable operation in both laminar and turbulent systems. We focus on these signals, challenges faced while detecting instabilities practical...
Over the past 5 years, a great deal of attention has been paid to the development of early warning systems for dropout prevention. These warning systems use a set of indicators based on official school records to identify youth at risk for dropout and then appropriately target intervention. The current study builds on this work by assessing the extent to which a school disengagement warning ind...
Critical transitions between alternative stable states have been shown to occur across an array of complex systems. While our ability to identify abrupt regime shifts in natural ecosystems has improved, detection of potential early-warning signals previous to such shifts is still very limited. Using real monitoring data of a key ecosystem component, we here apply multiple early-warning indicato...
The concept of developing early warning systems at a range of scales to reduce the likelihood of negatively impacting ecosystems is not new. Early warning systems are often developed in response to specific, immediate concerns such as major weather events (e.g., hurricanes, cyclones, tornados) or geo-physical events (e.g., earthquakes, tsunamis, tidal waves). There is also a need to develop ear...
Early Warning Systems (EWS) can play a crucial role in mitigating the effects of natural disasters. Modern EWSs leverage wireless sensors for real-time monitoring of natural phenomena and computing-intensive scientific applications for scenario-based prediction and analysis of sensor data. This paper presents the UrbanFlood Common Information Space (CIS), a framework facilitating the creation, ...
