Hybrid Semiconductor Detectors for High Spatial Resolution Phase-contrast X-ray Imaging
(University of Waterloo, 2019-02-20)When conventional x-ray radiography presents inadequate absorption-contrast, higher sensitivity can be achieved using phase-contrast methods. The implementation of phase-contrast x-ray imaging using propagation-based ... -
Mining Event Traces from Real-time Systems for Anomaly Detection
(University of Waterloo, 2019-02-19)Real-time systems are a significant class of applications, poised to grow even further as autonomous vehicles and the Internet of Things (IoT) become a reality. The computation and communication tasks of the underlying ... -
Formation and Removal of SOx and NOx in Pressurized Oxy-fuel Coal Combustion
(University of Waterloo, 2019-02-19)Growing concerns over greenhouse gas emissions have driven extensive research in carbon capture, storage and sequestration. Oxy-fuel combustion is a promising technology in CO2 capture, as the combustion products consists ... -
Step into the Void: A Study of Spatial Perception in Virtual Reality
(University of Waterloo, 2019-02-13)The introduction of virtual reality (VR) into the architectural profession offers an unprecedented opportunity to experience unbuilt designs at full scale. The premise of the technology is that it gives users the illusion ... -
Syntagmatic Space: violent articulations through photography
(University of Waterloo, 2019-02-11)This thesis examines the ways images come to bear on us: in our position as viewers and in their capacity to articulate violence. -
Time Synchronization in Distributed Systems without a Central Clock
(University of Waterloo, 2019-02-11)Time synchronization and a common understanding of the concept of time is an essential and important aspect of modern computing. Among the drawbacks of current and popular methods, such as the Network Time Protocol, ... -
The Squaring of the Circle: The Body According to Vitruvius – not daVinci
(University of Waterloo, 2019-02-07)An excerpt from a literary work of Classical literature is rendered in a self-directed manner. The literary passage in question is a specific description that is found in the third volume of a treatise on architecture, ... -
Starch modification for sustainable and functional material applications
(University of Waterloo, 2019-02-07)Among biodegradable polymers, starch has attracted significant interest and is currently used in numerous industrial applications. This is because of its renewability, biodegradability, abundance, and cohesive film-forming ... -
Robust Optimization of a Post-combustion CO2 Capture Absorber Column under Process Uncertainty
(University of Waterloo, 2019-02-07)In recent years, greenhouse gas (GHG) emissions is a global concern due to high concentrations of these gases in the atmosphere. Carbon capture and storage (CCS) has been suggested as an attractive alternative to curb ... -
Evaporation of Thin Lubricant Films under Laminar and Turbulent Boundary Layers
(University of Waterloo, 2019-02-07)The evaporation of engine oil hydrocarbons from the cylinder liner of internal combustion engines is a significant contributor to engine emissions. This evaporation occurs from the thin films deposited by the piston ... -
Cyber-Physical Security of Power Distribution Systems
(University of Waterloo, 2019-02-07)Smart grids have been witnessing continuous and rapid radical developments in the recent years. With the aim towards a more sustainable energy system, the share of distributed generation resources is ever-increasing and ... -
Efficient treatment of climate data uncertainty in ensemble Kalman filter (EnKF) based on an existing historical climate ensemble dataset
(Elsevier, 2019-01)Successful data assimilation depends on the accurate estimation of forcing data uncertainty. Forcing data uncertainty is typically estimated based on statistical error models. In practice, the hyper-parameters of statistical ... -
Modelling Microstructure-Property Relationships in Polycrystalline Metals using New Fast Fourier Transform-Based Crystal Plasticity Frameworks
(University of Waterloo, 2019-02-04)The present thesis develops several new full-field, fast Fourier transform (FFT)-based crystal plasticity modelling tools for microstructure engineering. These tools are used to explore elasto-viscoplastic deformation, ... -
The Detail, Photographed: Reimagining the Monument
(University of Waterloo, 2019-02-04)Architectural monuments lie scattered in small communities throughout Ontario, hidden by the everyday, masked by the sub-urban streets. The sub-urban streets where I lived felt impersonal and unnatural, with cookie-cutter ... -
Next-Generation Solid-State Quantum Emitters
(University of Waterloo, 2019-01-31)This thesis details two types of deterministic solid-state quantum emitters, an optically-driven quantum dot source in a tapered nanowire waveguide, and an electrically-driven source implemented by integrating a single-electron ... -
Improving Software Dependability through Documentation Analysis
(University of Waterloo, 2019-01-31)Software documentation contains critical information that describes a system’s functionality and requirements. Documentation exists in several forms, including code comments, test plans, manual pages, and user manuals. The ... -
Supercritical thermodynamic property evaluation via adaptive mesh tabulation
(University of Waterloo, 2019-01-30)Obtaining accurate computational simulations of fluid flows with a complex thermodynamic behaviour is difficult. This is partly due to the non-linear variation of thermophysical properties in the vicinity of critical point. ... -
