Computational and laboratory investigations of a model of blood droplet flight for forensic applicationsMurray, Raquel 01 September 2012 (has links)
We present a three-dimensional, forward model of blood droplets in
ight. The proposed
model is based on a set of ordinary di erential equations (ODEs) incorporating viscous
drag and gravitational forces. We validate the model against laboratory experiments
in which a mock crime scene is constructed. The experiments consist of a ballistics
gel containing transfer blood or porcine blood shot by a riot ball from a paintball gun
constituting a simulated bloodletting event. The experiments are captured using highspeed
stereo camera pair from which three-dimensional trajectories can be extracted
using tracking software. The long-term goal is to develop an accurate framework for
forensic Bloodstain Pattern Analysis (BPA). / UOIT
