A Contour Grouping Algorithm for 3D Reconstruction of Biological Cells
(University of Waterloo, 2009-08-20)Advances in computational modelling offer unprecedented potential for obtaining insights into the mechanics of cell-cell interactions. With the aid of such models, cell-level phenomena such as cell sorting and tissue ... -
Contributions from Healthcare Facilities to the overall Mass Loading of Pharmaceuticals on Wastewater Treatment Plants
(University of Waterloo, 2010-11-24)The presence of human pharmaceuticals in the aquatic environment is now becoming a well-established fact. The identified problems associated with their presence include the fact that these compounds are biologically active, ... -
Control-based Finite-element Model Updating of Structures
(University of Waterloo, 2010-01-05)Finite-element model updating is the process of using measured data from a structure to update a numerical model representation of the structure. The measured data can represent either the static or dynamic properties of ... -
Conventional and Oxidant-amended Biofiltration to Improve Treatment Resilience in Drinking Water Systems Vulnerable to Wildfire
(University of Waterloo, 2024-01-26)Climate-change-exacerbated landscape disturbances can create obstacles for the provision of safe drinking water. The threats posed by wildfires are of particular concern due not only to the potentially extreme nature of ... -
Correlation of Tensile Strength to Flexural Rupture Modulus of GFRP Bars
(University of Waterloo, 2021-05-04)Glass fibre reinforcing polymer (GFRP) bars are becoming a more comparable alternative to steel rebar used as tensile reinforcement for concrete, due to their cost effectiveness compared to other alternatives. GFRP has ... -
Coupled chemically-assisted filtration (CCAF) approaches for increasing filter resilience and performance during drinking water treatment
(University of Waterloo, 2021-05-11)The paramount objective of drinking water treatment is the prevention of acute waterborne disease. Filtration remains a critical barrier for ensuring that Cryptosporidium spp. and Giardia are removed during drinking water ... -
