It is very costly to conduct experiments to test smart environments installed in large-scale public spaces (e.g. airports and railway stations). As a tool to examine the design of such experiments beforehand, we developed a multiagent simulator integrating a large number of software agents and humans into a crowd that can produce complex group behaviors. In the testing of our emergency guidance...

surge and rotating stall phenomena are two dynamic instabilities that occur in both axial and centrifugal compressors. surge is the stream instability phenomenon in compressor that imposes severe damages to the compressors. nowadays, suppressing surge phenomenon is one of the most important issues in oil and gas industries, especially when flow reduction or gas reflux is considered. this resear...

Multiple noise measurements were taken on 6 types of fire station equipment and 15 types of emergency response vehicle-related equipment used by firefighters during routine and emergency operations at 10 fire stations. Five of the six types of fire station equipment, when measured at a distance of one meter and ear level, emitted noise equal to or greater than 85 dBA, including lawn maintenance...
