Ontario Tech acknowledges the lands and people of the Mississaugas of Scugog Island First Nation.

We are thankful to be welcome on these lands in friendship. The lands we are situated on are covered by the Williams Treaties and are the traditional territory of the Mississaugas, a branch of the greater Anishinaabeg Nation, including Algonquin, Ojibway, Odawa and Pottawatomi. These lands remain home to many Indigenous nations and peoples.

We acknowledge this land out of respect for the Indigenous nations who have cared for Turtle Island, also called North America, from before the arrival of settler peoples until this day. Most importantly, we acknowledge that the history of these lands has been tainted by poor treatment and a lack of friendship with the First Nations who call them home.

This history is something we are all affected by because we are all treaty people in Canada. We all have a shared history to reflect on, and each of us is affected by this history in different ways. Our past defines our present, but if we move forward as friends and allies, then it does not have to define our future.

Title: Using MATLAB in Bloodstain Pattern Analysis

Abstract: Forensic physics is a discipline within forensic science that involves the field of ballistics and bloodstain pattern analysis (BPA). Currently BPA is done using straight lines as a model for blood flight and rarely account for drag force and gravity in the models. In this talk I will be exploring the use of parabolic trajectories in modelling blood flight in MATLAB, the parameters associated with the flight of non newtonian droplets and the introduction of backwards tracking of blood droplets starting from the blood stain with limited initial conditions to the origin of the blood letting event.
