Basin-Scale Waves Dynamics and Sediment Resuspension Mechanics in Central Lake Erie
(2012-12-20)High-resolution physical and biogeochemical field data in central Lake Erie during the summers of 2008-2009 along with a three-dimensional numerical model were used to investigate the dynamics of basin scale waves and ... -
Batch and Bench-Scale Fixed-Bed Column Evaluations of Heavy Metal Removals From Aqueous Solutions and Synthetic Landfill Leachate Using Low-Cost Natural Adsorbents
(2008-02-01)In this project, three separate experiments were conducted to assess heavy metal removal from metal aqueous solutions and synthetic landfill leachate by adsorption using low-cost natural adsorbents. Fundamental batch ... -
Behavior of Sandwich Panels Subjected to Bending Fatigue, Axial Compression Loading and In-Plane Bending
(2015-01-26)This thesis investigates experimentally and analytically the structural performance of sandwich panels composed of glass fibre reinforced polymer (GFRP) skins and a soft polyurethane foam core, with or without thin GFRP ... -
Behaviour and Design of Reinforced Concrete Pipes
(2014-06-24)The overall objectives of this thesis are to determine if Indirect and Direct Design methods currently used for reinforced concrete pipe are able to accurately predict the capacity of the pipe, to identify discrepancies ... -
Behaviour of CFRP-Prestressed Concrete Beams under Sustained Loading and High-Cycle Fatigue at Low Temperature
(2009-12-22)Fibre-reinforced polymers (FRPs) are becoming increasingly accepted in structural engineering applications. In particular, Carbon-FRP (CFRP) tendons are proving to be promising as prestressing reinforcement for concrete ... -
Behaviour of Concrete Sandwich Wall Panels in Flexure Using a Novel GFRP Shear Connector
This thesis examines the structural effectiveness of a new concrete sandwich panel with a shear connector made of glass fibre reinforced polymer (GFRP) pultruded channel sections intended to enhance composite action and ... -
Behaviour of Deteriorated Pipes Rehabilitated With Grouted Slipliners
(2013-11-29)The goals of this research are to develop and validate the use of distributed fibre optic sensors for use in strain monitoring of buried culverts, and to use full-scale experiments to evaluate the performance of both ... -
Behaviour of Fibre Reinforced Polymer Confined Reinforced Concrete Columns Under Fire Condition
(2009-12-17)In recent years, fibre reinforced polymer (FRP) materials have demonstrated enormous potential as materials for repairing and retrofitting concrete bridges that have deteriorated from factors such as electro-chemical ... -
Behaviour of Partially Composite Precast Concrete Sandwich Panels under Flexural and Axial Loads
(2015-10-03)Precast concrete sandwich panels are commonly used on building exteriors. They are typically composed of two concrete wythes that surround rigid insulation. They are advantageous as they provide both structural and thermal ... -
Behaviour of Railway Bridge Transitions: New Insights From Digital Image Correlation And Distributed Fiber Optic Strain Sensing
Railway bridge transitions are locations of abrupt track support stiffness change arising from the difference in support stiffness between the relatively softer foundation materials of the track approaching the bridge and ... -
Biomass production and nutrient removal by Chlorella vulgaris as monoculture and in a consortium from centrate wastewater: optimization through acclimation
Microalgae-based wastewater treatment has shown promise in the removal of contaminants such as nutrients and heavy metals. Municipal wastewaters could be used as low-cost cultivation media as they provide the necessary ... -
Bioretention for Phosphorus Removal: Modelling Stormwater Quality Improvements
(2009-09-27)Bioretention systems are best management practices (BMPs) that make use of the biogeochemical processes within a forest-type ecosystem to provide at-source stormwater retention and pollutant removal. Laboratory studies and ... -
Calculating and Limiting Local Strains in Geomembranes From Gravel Indentations
(2013-10-02)Short-term tensile strains that arise from local gravel indentations in municipal solid waste landfill base geomembrane liners are investigated with an emphasis on quantifying how strains are obtained and providing methods ... -
Calculating Strain and Stress in Geomembranes at Gravel Indentations
New methods were developed, validated and applied to calculate strain and stress in geomembrane liners from the local deformed shape imposed by overlying coarse gravel under vertical pressure. Previous strain calculation ... -
Catalytic Supercritical Water Gasification of Sewage Sludge/Secondary Pulp/Paper-Mill Sludge for Hydrogen Production
(2012-10-19)Supercritical water gasification (SCWG) is an innovative hydrothermal technique, employing supercritical water (SCW, T≥374oC, P≥22.1 MPa) as the reaction media, to convert wet biomass or aqueous organic waste directly into ... -
Centrifuge Modelling of Instability in Granular Soils under Infinite Slope Conditions
(2013-12-04)Rainfall induced granular flow slides pose a significant risk in many areas of the world. These failures, characterized by the sudden release of material in a fluid-like manner, are the result of static liquefaction ... -
CFRP Tendons For The Repair Of Post-Tensioned, Ubonded Concrete Buildings
(2009-04-23)The deterioration of prestressed concrete structures due to corrosion is a costly problem. This problem is accelerated in cold weather climates where de-icing salts are used. These salts accelerate the corrosion of the ... -
Characterization and Prediction of Hyporheic Flow Induced by Bars in Gravel Streams
Hyporheic flows induced by bars in gravel streams are vital to the overall health of a river but can also be the primary mechanism for contamination to fish habitats. It is therefore of primordial importance to characterize ... -
Characterization and Thermal-Hydraulic Modeling of Engineered Barriers for a Canadian Deep Geological Repository for Used Nuclear Fuel
