A Laboratory Study on the Ability of Head Kinematics to Predict Brain Strains in Helmeted Head ImpactsDownload
Sports and recreation are a leading cause of traumatic brain injury (TBI) in North America, accounting for nearly 30% of TBI cases in youth in Canada. Contact sports, such as hockey and football, put athletes at greater risk of suffering mild traumatic brain injuries (mTBI, such as concussion),...
A Laboratory Study on the Effect of Helmet Fit on Biomechanical Measures of Head and Neck Injury in Simulated ImpactDownload
Conventional wisdom and the language in international helmet testing and certification standards suggest that appropriate helmet fit and retention during an impact are important factors in protecting the helmet wearer from impact-induced injury. This thesis aims to investigate impact-induced...
Autonomous navigation has been a popular research topic over the last two decades. The ability for a robot to solve the simultaneous localization and mapping (SLAM) problem is required to navigate unknown environments. One such example is a self-driving car: it needs to build maps of new...
Energy harvesting is an important developing field in Microelectromechanical Systems (MEMS) research. In this thesis, a fixed-fixed folded spring-based harvester is presented as an alternative mechanical element for beam-based piezoelectric harvesters to reduce its natural frequency for low...
A MIXED WETTABILITY PORE SIZE DISTRIBUTION MODEL FOR THE ANALYSIS OF WATER TRANSPORT IN PEMFC MATERIALSDownload
Water management on proton exchange membrane fuel cells is one of the biggest issues that stop the effective commercialization of this promising technology. Due to water flooding, the performance of fuel cells decays rapidly at high current densities. To better design fuel cell electrodes, a...
Braided composite materials are a class of fiber reinforced composite materials which obtain their unique material properties from the interlaced fiber structure. The fiber orientation has a critical impact on the resulting material properties of the composite component and as a result, the...
A Mixed Integer Linear Programming Optimization Model for Capturing Expert Planning Style in Interstitial Low Dose Rate Prostate BrachytherapyDownload
Low dose rate (LDR) brachytherapy is a minimally invasive form of radiation therapy, used to treat prostate cancer, and it involves permanent implantation of radioactive sources (seeds) inside of the prostate gland. Treatment planning in brachytherapy involves a decision making process for the...
Polymer electrolyte fuel cells (PEFCs) operate with a ternary mixture of fuel and reactants. The majority of numerical models in the literature, including the in-house Open-source Fuel Cell Simulation Toolbox (OpenFCST) software, use Fick’s law of diffusion which is only valid for binary...
A Novel Method of Measuring Refractory Black Carbon Mass and Number Distributions by Inversion of CPMA-SP2 DataDownload
A new method of examining mass and number distributions of nanoscale refractive black carbon (rBC) particles has been developed. This method will be useful for atmospheric scientists conducting semi-continuous measurement of atmospheric rBC. The new method uses a Centrifugal Particle Mass...
This study used non-intrusive, optical based measurement techniques in a parametric study of a flash atomized jet. The bench scale water spray was operated at pressure ratios ranging from 6.80-17.0 and degrees of superheat of 20-80 °C. This broad range of parameters allowed for the evaluation of...
