Wildlife territorial behavior play larger role disease spread thought
2020/6/19
Territorial behavior in wildlife, for example, pumas scent-marking their domains, may help decrease the severity of a potential disease outbreak -- but not without the cost of increased persistence of...
FIRE EVACUATION SIMULATION CONSIDERING THE MOVEMENT OF PEDESTRIAN ACCORDING TO FIRE SPREAD
Fire evacuation simulation Floor field model, Fire dynamics simulator Indoor evacuation Fire spread field Fire recognition field
