Statistical Modeling of Fracture Toughness Data
(University of Waterloo, 2007-09-25)The fracture toughness of the zirconium alloy (Zr-2.5Nb) is an important parameter in determining the flaw tolerance for operation of pressure tubes in reactor. Fracture toughness data have been generated by performing ... -
Analysis of Selected Pharmaceuticals and Endocrine Disrupting Compounds and their Removal by Granular Activated Carbon in Drinking Water Treatment
(University of Waterloo, 2007-09-25)Over the last decade, endocrine disrupting compounds (EDCs) and pharmaceutically active compounds (PhACs) have been detected in drinking water at very low levels, mostly ng/L concentrations, suggesting that these compounds ... -
Multiscale Modeling of Amphibian Neurulation
(University of Waterloo, 2007-10-23)This thesis presents a whole-embryo finite element model of neurulation -- the first of its kind. An advanced, multiscale finite element approach is used to capture the mechanical interactions that occur across cellular, ... -
Micromechanical Modelling of Polyethylene
(University of Waterloo, 2007-11-27)The increasing use of polyethylene in diverse applications motivates the need for understanding how its molecular properties relate to the overall behaviour of the material. Although microstructure and mechanical properties ... -
Impacts of the Introduction of an Express Transit Service in Waterloo Region
(University of Waterloo, 2008-01-08)For more than a century, public transportation has played a significant role in society. Transit agencies, like other service industries, are intent on improving their quality of service so as to increase transit ridership ... -
The effect of galvanized steel corrosion on the integrity of concrete
(University of Waterloo, 2008-01-16)The major concern regarding the use of hot-dip galvanized (HDG) steel as reinforcement in concrete has been the high rate of corrosion experienced by the zinc during the first hours in the fresh, wet, and highly alkaline ... -
Upstream River Responses to Low Head Dam Removal
(University of Waterloo, 2008-01-21)Field and modelling investigations of eight failed or removed dams have been undertaken to examine the upstream effects of low head dam decommissioning on channel morphology. Failed or decommissioned sites were selected ... -
A Case Study for Assessing the Hydrologic Impacts of Climate Change at the Watershed Scale
(University of Waterloo, 2008-01-23)Since the advent of the industrial era atmospheric concentrations of greenhouse gases have been on the rise leading to increasing global mean temperatures. Through increasing temperatures and changes to distributions of ... -
Climate impacts on hydrometric variables in the Mackenzie River Basin
(University of Waterloo, 2008-01-25)The research described in this thesis examines how the hydrologic cycle is affected by climate changes in the Mackenzie River Basin (MRB) in northern Canada. The study focuses on five hydro-meteorological variables; runoff, ... -
Effect of Biofiltration on DBP Formation at Full-Scale and Pilot-Scale
(University of Waterloo, 2008-01-25)Over the past century chlorine has been a reliable disinfectant to reduce transmission of waterborne diseases in drinking water. Concerns about chlorination have increased since it was discovered in the 1970s that use of ... -
Risk Assessment of a Water Supply System under Climate Variability: A Stochastic Approach
(University of Waterloo, 2008-01-28)In this study, a model is developed to assess risk to a municipal water supply system under the influence of population growth and climate change. To incorporate the uncertainly in water use, a model which combines time ... -
Multi-Level GIS-Based Data Management Model for Building Maintenance and Repair Data
(University of Waterloo, 2008-04-02)With the increasing cost of new construction projects, keeping the built facilities at acceptable levels of functionality has become a vital and challenging task. This is particularly so for non-residential buildings, such ... -
Punching Shear Retrofit Method Using Shear Bolts for Reinforced Concrete Slabs under Seismic Loading
(University of Waterloo, 2008-04-10)Reinforced concrete slab-column structures are widely used because of their practicality. However, this type of structures can be subject to punching-shear failure in the slab-column connections. Without shear reinforcement, ... -
Stochastic Stability of Flow-Induced Vibration
(University of Waterloo, 2008-05-07)Flow-induced structural vibration is experienced in many engineering applications, such as aerospace industry and civil engineering infrastructures. One of the main mechanisms of flow-induced vibration is instability which ... -
Stochastic stability of viscoelastic systems
(University of Waterloo, 2008-05-15)Many new materials used in mechanical and structural engineering exhibit viscoelastic properties, that is, stress depends on the past time history of strain, and vice versa. Investigating the behaviour of viscoelastic ... -
Detecting pathogenic Yersinia enterocolitica in surface water from the Grand River watershed: An evaluation and comparison of methods
(University of Waterloo, 2008-05-21)Yersinia enterocolitica are potentially pathogenic bacteria transmitted through the fecal oral route. Typical disease symptoms include those associated with gastrointestinal disease, although infection can also lead to ... -
Sample size effect in ultrasonic testing of geomaterials - numerical and experimental study
(University of Waterloo, 2008-05-21)Nondestructive evaluation of civil structures is of increasing interest to utility owners. Several methods exist to evaluate different properties of concrete, pavement, cemented sands and others. UPVM is the most commonly ... -
Strength of Cold-Formed Steel Jamb Stud-To-Track Connections
(University of Waterloo, 2008-05-22)Cold-formed steel structural members are used extensively in building construction, with a common application being wind load bearing steel studs. The studs frame into horizontal steel track members at the top and bottom ... -
