An evaluation of a dietary sodium reduction research consortium of five low-and middle-income countries in Latin America
(2023-04-01)
Background: Excess sodium consumption is a risk factor to cardiovascular disease (CVD). In Latin American countries (LAC), CVD rates are high. In LAC, policy development is complex and factors impacting research uptake ...
AI Adventure Camp: developing critical thinking and ethical artificial intelligence literacy through design fiction and digital constructionism
(2023-04-01)
Artificial intelligence is an increasingly influential aspect of our lives. From GPS to Siri and Amazon Echoes, our data is collected, stored, and analyzed throughout the day. Despite the ubiquity of AI, most STEM curricula ...
Performance assessment of Au SERS substrates prepared by deposition of Au nanoparticles on screen-printed SiO2 particle films
(2023-02-01)
Surface-enhanced Raman spectroscopy (SERS) is a highly studied technique for simple and rapid trace analysis. Screen-printing, a low-cost fabrication method, has been proposed as a reproducible and affordable approach for ...
Metabolic, neurotoxic and immunotoxic effects of PFAAs and their mixtures on the proteome of plasma and head kidney from rainbow trout
(2023-03-01)
PFAAs (Perfluoroalkyl acids) are a class of bioaccumulative, persistent and ubiquitous aquatic contaminants. A paucity of toxicological information exists for short chain PFAAs and PFAA mixtures. In order to address these ...
Design and evaluation of GAN-based models for adversarial training robustness in deep learning
(2023-04-01)
Adversarial attacks show one of the generalization issues of current deep learning models on special distribution shifted data. The adversarial samples generated by the attack algorithm can introduce malicious behavior to ...
Promoting self-determination amongst youth in conflict with the law: are advocates doing their part?
(2023-01-01)
This thesis used data from eleven advocacy reports published between 1998-2017 in the province of Ontario. The reports ranged from specific youth facilities such as the Roy McMurtry and Hamilton Wentworth centers to reports ...
Autonomous driving control strategies for multi-trailer articulated heavy vehicles with active safety system
(2023-05-01)
This study aims to develop automated driving strategies and integrated active control system for multi-trailer articulated heavy vehicles (MTAHVs) to enhance road transport efficiency, directional performance, and safety. ...
Investigation and use of dual (twin) low pressure proportional counters for active neutron-gamma mixed field dosimetry
(2023-05-01)
This thesis tackles accurate neutron-gamma mixed field dosimetry in radiation protection and radiation biology. While passive dosimeters are suitable for measuring low radiation levels, active instruments are necessary in ...
Experimental and numerical investigation of the flow structures at the rear of three-dimensional bluff bodies
(2023-05-01)
Flows around bluff bodies have complex structures, which create drag, surface contamination and stability issues for transportation systems. The standard Ahmed body (SAB) is a simplified representative three-dimensional ...
Investigation into the stability of low-inertia micro-grids
(2023-05-01)
This work examines the stability of low inertia micro-grids (MGs). The lack of inertia in such power electronics dominated grid is a pressing matter that directly impacts its operation and stability. The investigated MG ...
