With advantages of IOT (internet of things) and sensor technique, a new communication mechanism between sensors is enhanced upon which distributed emergency response systems are built. This mechanism enables sensors to cooperate with each other in a decentralized way to improve efficiency in case of emergencies. During the process, the alert messages are(More)
Scheduling performance in computational grid can potentially benefit a lot from accurate execution time estimation for parallel jobs. Most existing approaches for the parallel job execution time estimation, however, require ample past job traces and the explicit correlations between the job execution time and the outer layout parameters such as the consumed(More)
Pial arteriovenous fistulas (AVFs) of the brain are rare vascular malformations associated with significant risk of hemorrhage and neurological deficits. Depending on their location and high-flow dynamics, these lesions can present treatment challenges for both endovascular and open cerebrovascular surgeons. We present a novel approach to treat intracranial(More)
Social media sites contain a considerable amount of data for natural calamities events, such as earthquakes, snowstorms, mud-rock flows. With the increasing amount of social media data, an important task is to discover and retrieve sub-events over time. Especially in emergency situations, rescue and relief activities can be enhanced by identifying and(More)
