Fermentation of Food Waste in a Leach Bed Reactor- Effects of pH and Inoculum to Substrate Ratio
(University of Waterloo, 2018-12-19)A more sustainable method for the treatment of accumulated food waste, instead of landfilling, is in urgently need. Fermentation is one of the most promising waste-to-energy technologies for energy recovery from food waste. ... -
A field and Numerical Investigation of the Pressure Pulsing Reagent Delivery Approach
(University of Waterloo, 2011-09-30)The efficacy of injection-driven remediation techniques for non-aqueous phase liquid (NAPL) source zones is limited by the principle that fluid flow is focused along paths of least hydraulic resistance. The pressure pulse ... -
Field and Numerical Investigation to Determine the Impact of Environmental and Wheel Loads on Flexible Pavement
(University of Waterloo, 2009-08-24)There is a growing interest for the use of mechanistic procedures and analytical methods in the design and evaluation of pavement structure rather than empirical design procedures. The mechanistic procedures rely on ... -
Field Evaluation and Performance Analysis of Different Pre-wetting Ratios for Sustainable Salting
(University of Waterloo, 2018-09-20)In countries like Canada road safety and mobility could be compromised to a great extent during winters due to deterioration of road surface conditions (RSC). Adverse winter weather conditions such as ice, frost, and ... -
A Field Study of Airflow in a High-Rise Multi-Unit Residential Building
(University of Waterloo, 2014-01-23)Airflow into, out of, and within buildings is fundamental to their design and operation as it can affect occupant health and comfort, building durability, and energy consumption. This thesis works to develop the understanding ... -
Fine Sediment Contributions to Cyanobacterial Growth: Potential Threats to Drinking Water Reservoirs
(University of Waterloo, 2019-01-14)In the drinking water industry, the transport and release of nutrients such as phosphorus (P) to the water column is largely overlooked in reservoir management. Phosphorus is considered the key limiting nutrient for algal ... -
Finite Difference-Boundary Element Methods in Infinite and Semi-infinite Media in Geomechanics
(University of Waterloo, 2013-02-22)The engineering problems in Geomechanics and Geotechnical fields are commonly treated through the infinite or semi-infinite media. The best approach to solve these problems numerically is by coupling a finite element or a ... -
Finite Element Analysis Workflow for Heat Straightening of Impact-Damaged Steel Bridges
(University of Waterloo, 2015-09-11)Impacts between over-height vehicles and steel bridges are common throughout North America and the resulting bridge damage is unpredictable and sudden. Heat straightening is an alternative to replacing steel members and ... -
A Finite Element Investigation of Possible Mechanisms of Luminal Cell Escape from the Mammary Duct: An Initial Step in Breast Cancer Metastasis
(University of Waterloo, 2017-06-14)Cancer is an illness that kills some ten million people every year, and as cancer rates increase, a cure for metastatic disease is more necessary than ever. Breast cancer is the most common form of malignancy in the female ... -
Finite Element Model of a Two-cell Contact and Separation Experiment
(University of Waterloo, 2009-01-08)Cell-cell adhesion is important to understanding the mechanics of cell-cell interactions. A recent study of cell adhesion was conducted by others using an Atomic Force Microscopy to measure forces when two cells are brought ... -
Finite Element Modelling of FRP Reinforced Concrete Beams and Comparative Analysis of Current Strength Prediction Methods
(University of Waterloo, 2017-05-23)The modelling of glass fibre reinforced polymer (GFRP) reinforced, concrete beams was conducted by the author in the finite element analysis software ABAQUS. The study extended upon the work done by Joseph Stoner (2015) ... -
Finite Element Modelling of GFRP Reinforced Concrete Beams
(University of Waterloo, 2015-04-29)The numerical modelling of twelve concrete beams reinforced with glass fibre reinforced polymer (GFRP) longitudinal and transverse bars was performed by the author using the finite element analysis (FEA) software ABAQUS. ... -
Finite Element Modelling of RC Beams Strengthened with Prestressed NSM CFRP Plate
(University of Waterloo, 2021-04-30)Near Surface mounted (NSM) carbon fibre reinforced polymer (CFRP) reinforcement has become a promising flexural strengthening technique for reinforced concrete (RC) elements. The prestressing of a CFRP plate can be used ... -
Finite Element Studies of an Embryonic Cell Aggregate under Parallel Plate Compression
(University of Waterloo, 2008-08-25)Cell shape is important to understanding the mechanics of three-dimensional (3D) cell aggregates. When an aggregate of embryonic cells is compressed between parallel plates, the cell mass and the cells of which it is ... -
Flexural Behavior and Strength of Cold-formed Steel L-Headers
(University of Waterloo, 2008-08-25)Cold-formed steel framing of residential and light commercial buildings continues to grow in popularity due to its structural and material advantages. The North American steel industry is actively performing research ... -
