Contributors to Proximal Femur Fracture Force: Multiscale Considerations of Rate, Toughness, and Bone Composition
(University of Waterloo, 2022-06-09)Fall-related hip fractures are a major concern facing the older adult population, especially as rates of these injuries increasing worldwide. Based on the strong positive relationship between femoral areal bone mineral ... -
Control and Interfacing of Three Phase Grid Connected Photovoltaic Systems
(University of Waterloo, 2011-01-10)Solar power is considered a very promising source for electric power generation. The abundance of sunlight over a large area of the earth surface gives rise to several applications of photovoltaic systems. Electricity can ... -
Control and Readout of High-Dimensional Trapped Ion Qudits
(University of Waterloo, 2023-09-07)The trapped ion platform is one of the quantum computing platforms that is at the forefront for realizing large-scale quantum information processing, which is crucial for practically actualizing the advantages of quantum ... -
Control Loop Interactions and Their Mitigation Schemes in VSC-HVDC Systems
(University of Waterloo, 2023-01-23)In line with two goals of the United Nations, i.e., providing affordable and clean energy as well as combating climate change, various converter-interfaced renewable energy sources (RESs) are being integrated into the power ... -
Control Mechanisms in Queueing Systems with Nonlinear Waiting Costs
(University of Waterloo, 2017-08-14)In many queueing systems, customers have been observed to exhibit strategic behavior. Each customer gains a value when receiving a product or getting served and suffers when incurring a delay. We consider a nonlinear ... -
Control Methods for Improving Tracking Accuracy and Disturbance Rejection in Ball Screw Feed Drives
(University of Waterloo, 2014-01-23)This thesis studies in detail the dynamics of ball screw feed drives and expands understanding of the factors that impose limitations on their performance. This knowledge is then used for developing control strategies that ... -
Control of Dynamic Stability during Gait Termination on a Slippery Surface
(University of Waterloo, 2007-01-17)The purpose of this thesis is to investigate the reaction to a purely unexpected slip during gait termination and subsequent experiences stopping on the slippery surface in participants who are young and healthy, older and ... -
The Control of Fe and pH on the Photodegradation and Characterization of Dissolved Organic Matter in Small, Oligotrophic Canadian Shield Freshwaters
(University of Waterloo, 2017-05-19)Carbon is an essential building block for life and is involved in many biotic and abiotic processes. Thus it is imperative to have a comprehensive understanding of carbon cycling. Recent research has established that inland ... -
Control of Fluid Flow and Species Transport within Microchannels of Microfluidic Chips
(University of Waterloo, 2008-09-26)Microfluidic chips have drawn great attention and interest due to their broad applications in chemical, biological and biomedical fields. These kinds of miniaturized devices offer many advantages over the traditional ... -
Control of Hysteresis in the Landau-Lifshitz Equation
(University of Waterloo, 2013-11-15)There are two main tools for determining the stability of nonlinear partial differential equations (PDEs): Lyapunov Theory and linearization. The former has the advantage of providing stability results for nonlinear ... -
Control of Light-Matter Interactions in Classical and Quantum Optics
(University of Waterloo, 2018-01-12)In this thesis, we examined a series of techniques for controlling the interaction of light with matter that could be employed to optimize or to control physical phenomena in various potential applications. Some of these ... -
Control of Microstructure in Laser Additive Manufacturing
(University of Waterloo, 2014-09-22)Since its arrival in the late 1980’s, Laser Additive Manufacturing (LAM) has come a long way to establish itself as one of the most advanced versatile manufacturing technologies in the 21st century. LAM implies a novel ... -
Control of Non-deterministic Transition Systems for Linear Temporal Logic Specifications
(University of Waterloo, 2021-02-01)Consider the formal synthesis problem in the continuous dynamical systems. A systematic approach is the abstraction-based method: constructing an abstraction of the original continuous system in the discrete space, and ... -
