As a high-risk subindustry involved in construction projects, highway construction safety has experienced major developments in the past 20 years, mainly due to the lack of safe early warnings in Chinese construction projects. By combining the current state of early warning technology with the requirements of the State Administration of Work Safety and using case-based reasoning (CBR), this pap...
Among the properties that are common to complex systems, the presence of critical thresholds in the dynamics of the system is one of the most important. Recently, there has been interest in the universalities that occur in the behavior of systems near critical points. These universal properties make it possible to estimate how far a system is from a critical threshold. Several early-warning sig...
This special issue aims at fostering the dissemination of high-quality research in methods, theories, and techniques concerning the application of knowledge and asset management in sustainable civil engineering. Similar to that of other special issues, the selection process was rigorous and only articles with good quality could be accepted. We, as editors, would like to thank all of those who h...
We demonstrate a flexible strategy for local tsunami warning that relies on regional geodetic and seismic stations. Through retrospective analysis of four recent tsunamigenic events in Japan and Chile, we show that rapid earthquake source information, provided by methodologies developed for earthquake early warning, can be used to generate timely estimates of maximum expected tsunami amplitude ...
Shifting patterns of temporal fluctuations have been found to signal critical transitions in a variety of systems, from ecological communities to human physiology. However, failure of these early warning signals in some systems calls for a better understanding of their limitations. In particular, little is known about the generality of early warning signals in different deteriorating environmen...
Landslide monitoring and early warning systems are the most successful countermeasures to reduce fatalities and economic losses from landslide hazards. The traditional strategies such as GPS and extensometers are relatively expensive and difficult to be installed in steep, high mountains. In this study, a MEMS (Micro Electro Mechanical Systems) based multivariate wireless monitoring sensor unit...
BACKGROUND Disaster identification and alert systems can be processed in dif-ferent ways. An early warning system is designed to detect impending danger and send appropriate and clear signals to at risk communities and organizations at the right time and in an unambiguous way. This study aimed to determine early warning system for disaster within health organization in Iran. METHODS This arti...
