Determinants of fracture risk among individuals with spinal cord injury: a case control study
(University of Waterloo, 2011-05-02)Background/Objectives: Low areal bone mineral density (aBMD) of the hip and knee region has been associated with fracture risk in individuals with SCI; however the contribution of bone micro-architecture to fracture risk ... -
Determinants of HIV Testing in East African Communities in Toronto
(University of Waterloo, 2006)<strong>Background. </strong> Previous evidence suggests that persons who have emigrated from HIV-endemic countries experience higher rates of HIV infection and delayed diagnosis. Despite this evidence, limited research ... -
Determinants of Immigrant Food Security: An Examination of the Food Environment in the Region of Waterloo, Ontario
(University of Waterloo, 2015-05-15)This study aimed to explore the role of the food environment in shaping immigrants’ access to food and ultimately their health. A growing body of research is examining the influence of food environments—defined as everything ... -
Determinants of Increased Energy Cost in Prosthetic Gait
(University of Waterloo, 2004)The physiological energy requirements of prosthetic gait in lower-limb amputees have been observed to be significantly greater than those for able-bodied subjects. However, existing models of energy flow in walking have ... -
Determinants of Object Persistence: The Role of Cue Type, Cue Duration and Cue Strength
(University of Waterloo, 2008-08-28)Four experiments investigated object persistence in conscious awareness as a function of the nature of the cues that permit the object to be segregated from the background, and identified. A number of factors were manipulated ... -
Determinants of Profitability and Recovery from Shocks: the case of the U.S. domestic Airline Industry
(University of Waterloo, 2009-08-26)This paper examines the determinants of profitability using operations strategy, productivity, and service measures in the context of the U.S. domestic airline industry. Data on ten carriers was collected on a quarterly ... -
Determinants of Rapid Transit Planning Processes in Ecuador
(University of Waterloo, 2021-06-21)This research presents a novel framework for the quantitative and qualitative analysis of rapid transit planning processes based on a mixed-method approach, along with the corresponding results: the relative importance of ... -
The Determinants of Reaction Times: Influence of Stimulus Intensity
(University of Waterloo, 2015-12-07)The central nervous system has the ability to generate very rapid ‘temporally urgent’ sensory motor reactions in response to stimuli under certain conditions. For example, temporally urgent reactions have been shown to ... -
Determinants of Undetected Unintentional Errors in Audited Financial Statements
(University of Waterloo, 2014-12-18)This dissertation investigates the associations between financial restatements and characteristics of the parties responsible for preventing and detecting unintentional errors, i.e., boards (through their audit committees), ... -
Determination of Characteristic Transport Coefficients of Porous Media from Volumetric Images using the Diffuse Interface Method
(University of Waterloo, 2021-11-24)Transport in engineered materials such as electrodes, membranes, filters, and natural materials such as rock, sand, soil can be modeled as transport in porous media. Direct Numerical Simulations (DNS) on volumetric images ... -
Determination of Geosmin and 2-Methylisoborneol in Fish using In-vivo Solid Phase Microextraction
(University of Waterloo, 2012-08-31)The presence of off-flavor compounds in fish represents one of the significant economic problems encountered in aquaculture. These off-flavor compounds are due to the absorption of substances produced by microorganisms. ... -
Determination of internal friction angle of rock materials using the drilling data
(University of Waterloo, 2022-08-25)Rock cutting is a critical process occurring in several rock excavation activities such as drilling, cutting, sawing, and is common across various industries such as petroleum, geothermal, geo-technical, and underground ... -
The determination of structured Hessian matrices via automatic differentiation
(University of Waterloo, 2014-09-23)In using automatic differentiation (AD) for Hessian computation, efficiency can be achieved by exploiting the sparsity existing in the derivative matrix. However, in the case where the Hessian is dense, this cannot be done ... -
Determination of the fracture strength of brittle material thin films at high temperature using MEMS
(University of Waterloo, 2020-01-27)Brittle materials are widely used as structural materials in microelectromechanical systems (MEMS). Their mechanical properties make them suitable for high-temperature environments where MEMS are exposed to different types ... -
Determination Of Thermal Properties Of Mineral Wool Insulation Materials For Use In Full-Scale Fire Modelling
(University of Waterloo, 2020-03-19)Temperature-dependent materials properties are required for use in many contexts in fire safety engineering. While property values for many materials do exist, we often are limited in our understanding of how representative ... -
Determining Analytical Potential Energy Functions of Diatomic Molecules by Direct Fitting
(University of Waterloo, 2001)The fully quantum mechanical 'direct-potential-fit' (DPF) method has become increasingly widely used in the reduction of diatomic spectra. The central problem of this method is the representation of the potential energy ... -
Determining food web impacts on experimental aquatic systems from the disposal of oil sands process-affected waste materials.
(University of Waterloo, 2006)Current mining operators in the Athabasca oil sands deposit of Alberta, Canada have made commitments to zero discharge of oil sands process-affected waste materials (OSPM) from the mine site and rehabilitation of mined ... -
