Behaviour of Helical Pile Groups and Individual Piles under Compressive Loading in a Cohesive Soil
DownloadFall 2017
Helical piles are becoming increasingly common as a result of their wide range of foundation applications. This pile type consists of a steel shaft with one or more helical plates welded near the toe. The axial behaviour of this pile type is difficult to predict because the failure mode is...

Behaviour of Low-Rise Shear Walls with Hybrid GFRP-Steel Reinforcement and Steel Fibre-Reinforced Concrete
DownloadFall 2017
Recent earthquakes have revealed that conventional steel-reinforced concrete (RC) shear walls can exhibit considerable damage and residual displacements even after moderate intensity earthquakes. These residual displacements can result in high post-earthquake repair costs. Recent advances in the...

Cancers in the head and neck often lead to disability in basic functions, including speech and swallowing. Restoration of these functional impairments is the main treatment goals in managing patients affected by head and neck cancer. Historically, expert stakeholders including clinicians and...

Teaching portfolios have been used by faculty in postsecondary institutions for summative and formative evaluations since the early 1980s (Knapper, 1995). Despite their proliferation, there remains much to be learned about the use of teaching portfolios and whether they are perceived as being...

Strains of Escherichia coli may survive heat or pressure stress, acquire specific virulence genes and cause severe human diseases. The locus of heat resistance (LHR) has been identified as an important heat resistant element in E. coli. The objective of this thesis was to explore the role of the...

Efficient algorithms for least squares wave equation migration and source signature estimation
DownloadFall 2017
Estimating accurate images of the subsurface is one of the end products of seismic data processing. Numerical solutions to the wave equation allow designing linearized forward operators. The adjoint of the linearized forward operator is used to image the interior of the earth. The adjoint...

Severe localized corrosion was found throughout an aeration tank of a modular wastewater treatment plant. Specifically, pitting, crevice corrosion, galvanic corrosion, and intergranular corrosion (IGC) were observed on the 5000 and 6000 series aluminum alloys used in the tank’s construction. One...

In this thesis, some topics in convex geometric analysis and discrete tomography are studied. Firstly, let K be a convex body in the n-dimensional Euclidean space. Is K uniquely determined by its sections? There are classical results that explain what happens in the case of sections passing...

Enabling Flexible Electronics: Demonstration of the Tunneling Junction Transistor (TJT) and Flexible Circuit Elements
DownloadSpring 2018
Thin-film technology continues to evolve as it finds new technological spaces to fulfill that will inevitably lead to an increased integration between society and technology. The aims of this research are to push beyond the limits of thin film electronics to enable a new era of flexible...

Relationships between bovine phenotype, production practices, muscle proteins and the incidence of dark cutting beef
DownloadFall 2017
Most recent reports indicated that the prevalence of dark cutting beef has increased in Canada and that 0.5% reduction in the problem could save CAD$1.77 million per annum. Understanding the underlying factors associated with the persistence and recent escalation in the occurrence of dark-cutting...
