Many uncertainties are introduced inevitably during estimating fire risk for life safety in buildings. Probabilistic methods, the most widely used method to deal with uncertainties, require a large number of historical data. Due to the uniqueness of building fires, such data are rarely available. In order to address this limitation, a fuzzy risk assessment method for life safety under building fires...
To characterize the periodic pulsation of flame from the flame image sequence, several novel methods for flame pulsation measurement were introduced and demonstrated based on flame image analysis. Results show that moment function of flame image, such as weighted Euclidean distance and cross correlation coefficient, could represent the geometric and periodic flame pulsation; and that both the vertical...
