A COMPUTER-AIDED METHOD FOR QUANTITATIVELY DETERMINING THE POINT OF ORIGIN AND FOR ASCERTAINING THE TIME OF IGNITION OF A FIRE.
Abstract
THE METHOD OF SOLUTION RELIES ON A COMPUTER PROGRAM WHICH REGRESSIVELY CONSTRUCTS THE LOCATION OF THE PREVIOUS FIRE PERIMETER WHICH OCCURRED AN ARBITRARILY CHOSEN TIME UNIT PRIOR TO THE ONE OBSERVED. THIS PROCEDURE IS REPEATED OBTAINING A SERIES OF CONCENTRIC BURN PERIMETERS. THE PROGRAM TERMINATES WHEN THE BURN PERIMETER CONVERGES TO A SUITABLE WORKING AREA FOR THE INVESTIGATOR. FUTURE ADVANCEMENTS CAN BE MADE TO TAKE INTO ACCOUNT HETEROGENEOUS AND TIME-VARYING CONDITIONS. (AUTHOR ABSTRACT)
