In this project, I concentrate on critical event monitoring occur in wireless sensor networks (WSNs), most of the time small number of packets get transmit on network. When critical event occurs, an alarm message should be broadcast to the entire network as soon as possible. To elongate the network lifetime, in WSNs some sleep scheduling methods are always employed. Resulting in significant del...

Mechanical ventilators are designed to generate alarms when patients become disconnected or experience other critical ventilator events. However, these alarms can blend in with other accustomed sounds of the intensive care unit. Ventilator alarms that go unnoticed for extended periods of time often result in permanent patient harm or death. We developed a system to monitor critical ventilator e...

Background: Hospital surge capacity (HSC) is essential to the successful management of expected consequences of disasters and mass casualty incidents (MCIs). In MCIs, an unanticipated number of sick or injured people refer to the hospital, and thus, the hospital is faced with a significant increase in the burden of necessary activities and services. Therefore, managing the process in order to m...

The notions of the critical path of events and critical time of an event are key concepts in analyzing the performance of a parallel discrete event simulation. The highest critical time of any event in a simulation is a lower bound on the time it takes to execute a simulation using any conservative simulation mechanism, and is also a lower bound on the time taken by some optimistic methods. How...

Collaboration is essential for value creation in the modern business environment, may span across organizational and geographical boundaries and is often used for mission critical tasks. Collaborative environments are subject to continuous changes because participation is dynamic and business goals may be evolving. In such dynamic environments there is a need for adapting the ways of collaborat...

Event anaphora resolution plays a critical role in discourse analysis. This paper proposes a tree kernel-based framework for event pronoun resolution. In particular, a new tree expansion scheme is introduced to automatically determine a proper parse tree structure for event pronoun resolution by considering various kinds of competitive information related with the anaphor and the antecedent can...

Complex event processing is a popular technology for continuously monitoring high-volume event streams from health care to traffic management to detect complex compositions of events. These event compositions signify critical “application contexts” from hygiene violations to traffic accidents. Certain event queries are only appropriate in particular contexts. Yet state-of-the-art streaming engi...
