The Cadaveric Response to Concussive Impact: Tracking brain tissue displacement and strain fields with high-speed X-ray imaging

Professor Oren Petel has received a Carleton University Research Achievement Award, which recognizes outstanding research achievements and excellence.

A state-of-the-art X-ray system, jointly funded by the Canadian Foundation for Innovation and the Ontario Research Fund, is currently being used to advance injury biomechanics knowledge. Prof. Oren Petel and his Impact Dynamics Research Group (carleton.ca/impact) have focused on developing new tools and techniques to complement existing helmet evaluation methodologies. “Our ultimate goal is to use a new paradigm to guide future helmet design” says Prof. Petel.

Prof. Petel’s custom and unique high-speed X-ray imaging system, designed and built in his lab with his research team, has enabled multidisciplinary research measuring the relative motion between the brain and skull of cadavers, data required to calibrate brain injury models. His research group currently works with commercial helmet designers to translate their innovations outside of the university, in an effort to reduce concussion incidence, and ultimately benefit public health.

Adaptive Coordinated Motion Control of Free-Floating Space Robots

Professor Steve Ulrich’s research in the area of autonomous robotics and controls for spacecraft proximity operations was recently recognized by two major awards. Funding from the Ontario Ministry of Economic Development, Job Creation and Trade through the Early Researcher Awards (ERA) program and from Carleton University’s Research Achievement Award (RAA) will allow Prof. Ulrich to address challenging problems related to autonomous proximity operations with uncooperative space debris.

With these two prestigious awards, Prof. Ulrich and his research team will develop adaptive algorithms to modify, in real-time, the behavior of the on-board guidance, navigation and control system, thereby enabling a robotic spacecraft to autonomously and safely interact with space debris.

Experimental validation of the innovative algorithms will be conducted with the Spacecraft Proximity Operations Testbed; a unique gravity-offset facility in Canada which is part of Prof. Ulrich’s Spacecraft Robotics and Control Laboratory.
