3D-Mapping Optimization of Embodied Energy of Transportation
(Elsevier, 2007)The recent development of Google Earth, an information service that provides imagery and three dimensional data depicting the entire Earth, provides an opportunity to use a new method of navigating information to save ... -
Adjustable Wheelchair Obstacle Simulator and Instrumentation for Assessing Wheelchair Suspension
(2010-02-01)Wheelchair users are exposed to whole-body vibrations, particularly when traversing rugged terrain such as in less resourced areas. Suspension systems have been added to wheelchair systems to protect occupants from secondary ... -
Advanced Characterization of Hydrides in Zirconium
Zirconium and its alloys are of great importance to the nuclear power industry due to their unique combination of mechanical properties, low neutron-capture cross-section, and sufficient corrosion resistance under reducing ... -
Advanced Devolatilisation model for Lagrangian particles in OpenFOAM
To study the devolatilisation process associated with coal combustion, computational fluid dynamics (CFD) is a very useful tool. The aim of this thesis is to accurately model coal devolatilisation at high temperatures ... -
Advanced Techniques for the Characterization of Hydrided Zirconium Alloy
(2011-01-18)Zirconium alloy pressure tubes are an important component in CANDU nuclear reactors. During operation these tubes can pick up hydrogen as a result of a corrosion reaction, which can eventually lead to the precipitation ... -
Altering Compliance of a Load Carriage Structure in the Medial-Lateral Direction
For work or recreation, many individuals transport heavy loads within a backpack. Carrying substantial weight while walking typically causes an increase in muscle activity, metabolic energy expenditure, and increases ... -
Alternating Current Electroosmotic Micropumping Using A Square Spiral Microelectrode Array
(2011-04-06)An alternating current electroosmotic micro pumping device has been designed, experimentally tested and theoretically analyzed using an electrohydrodynamic theoretical model applied to a computer simulation model. The ... -

(2014-09-11)The overall goal of this study is to advance the availability of prosthetic devices for developing and post conflict regions by establishing a framework for their design based on those used for Class II medical devices. ... -
Analysis of a Flat-Plate, Liquid-Desiccant, Dehumidifier and Regenerator
(2008-01-14)A numerical model for isothermal and non-isothermal flat-plate liquid-desiccant dehumidifiers and regenerators was developed and implemented. The two-dimensional model takes into account the desiccant, water and air flow ... -
Analysis of Hydride Effects in Zr-2.5Nb Micro Pressure Tubes
(2010-10-06)During operation of a CANDU reactor, corrosion occurs which results in free hydrogen that can diffuse into the tubes. Once the solid solubility of hydrogen in the zirconium matrix is exceeded, the hydrogen will precipitate ... -
Analysis of Non-Stationary Flows Using Eulerian and Lagrangian Frameworks
Recent developments have made researchers to reconsider Lagrangian measurement techniques as an alternative to their Eulerian counterpart when investigating non-stationary flows. This thesis advances the state-of-the-art ... -
Anisotropic Strength-Based Topology Optimization for Part Design Using Additive Manufacturing
Additive manufacturing (AM), specifically the process of Fused Deposition Modelling (FDM), is a manufacturing procedure where a part is constructed by extruding a melted filament in a layer-by-layer fashion from the bottom ... -
Appropedia as a Tool for Service Learning in Sustainable Development
(Sage, 2009)Numerous studies have demonstrated that university students are capable of contributing to sustainable development while improving their academic skills. Unfortunately for many institutions, the expense of sending large ... -
Articular Asphericity of the Arthritic Hip
(2011-09-28)The predominant model of the human hip is a mechanical ball-and-socket joint. This description has two key implications: that the motion of the hip is purely rotational, and that the rigid articulating geometry of the hip ... -
Artificial Neural Networks for Fault Detection and Identification on an Automated Assembly Machine
(2014-05-20)Artificial neural networks (ANNs) have been used in many fault detection and identification (FDI) applications due to their pattern recognition abilities. In this study, two ANNs, a supervised network based on Backpropagation ... -
Atomistic simulations of irradiation-induced dislocation loops in zirconium alloys
Irradiation-induced dislocation loops are important defects that affect zirconium alloys used in the manufacture of major structural components of nuclear reactors. In this thesis atomistic simulations and theoretical ... -
