Variations on a Theme of Deep Time: From Geology to Architecture
(University of Waterloo, 2015-08-27)Through the lens of deep time, this thesis draws a comparison between geology and architecture, to create an architecture of simultaneity. Using Henri Bergson’s notion of the present containing all of the past within it, ... -
Variations on a Theme: Graph Homomorphisms
(University of Waterloo, 2013-08-30)This thesis investigates three areas of the theory of graph homomorphisms: cores of graphs, the homomorphism order, and quantum homomorphisms. A core of a graph X is a vertex minimal subgraph to which X admits a ... -
Variations on Acoustophoretic Microchannels: From the Facile to the Highly Capable
(University of Waterloo, 2018-05-31)The lab-on-a-chip toolkit is replete with techniques for microparticle manipulation. The use of ultrasonic waves to impart forces on particles, referred to as acoustophoresis, is one particularly powerful yet gentle option. ... -
Variations on PIGS: Non-standard approaches for imaginary-time path integrals
(University of Waterloo, 2015-08-21)The second Rényi entropy has been used as a measure of entanglement in various model systems, including those on a lattice and in the continuum. The present work focuses on extending the existing ideas to measurement of ... -
Variations on the Erdos Discrepancy Problem
(University of Waterloo, 2012-01-04)The Erdős discrepancy problem asks, "Does there exist a sequence t = {t_i}_{1≤i<∞} with each t_i ∈ {-1,1} and a constant c such that |∑_{1≤i≤n} t_{id}| ≤ c for all n,c ∈ ℕ = {1,2,3,...}?" The discrepancy of t equals ... -
Variations on the Theme of Caching
(University of Waterloo, 2005)This thesis is concerned with caching algorithms. We investigate three variations of the caching problem: web caching in the Torng framework, relative competitiveness and caching with request reordering. <br /><br /> ... -
Various aspects of single bacterial cell: from encapsulating nanoparticle, cell patterning and studying gene expression
(University of Waterloo, 2016-11-15)Behaviour of single bacterium have been mysterious for many years due to the technical difficulty and nature of bacteria forming communities. It has not been long since engineers and scientists have started to develop ... -
Vascular Aging: Influences on cerebral blood flow and executive function
(University of Waterloo, 2007-09-17)An age-related decline in cerebral blood flow (CBF) is widely acknowledged. However, uncertainty exists as to whether this reduction is the result of a reduced metabolic demand (cerebral atrophy) or an impaired delivery ... -
Vector Bundles on Non-Kähler Elliptic Surfaces
(University of Waterloo, 2023-04-20)This thesis studies two problems relating to moduli spaces of vector bundles on non-Kähler elliptic surfaces. The first project involves the holomorphic symplectic structure on smooth and compact moduli spaces of sheaves ... -
Vector Graphics for Real-time 3D Rendering
(University of Waterloo, 2009-01-27)Algorithms are presented that enable the use of vector graphics representations of images in texture maps for 3D real time rendering. Vector graphics images are resolution independent and can be zoomed arbitrarily ... -
Vegetation Based Assessment of Wetland Condition in the Prairie Pothole Region
(University of Waterloo, 2018-01-22)The northern prairie pothole region (NPPR) in central and southern Alberta contains numerous shallow, open-water pothole wetlands that provide important ecosystem services to the region, such as flood mitigation. To address ... -
Vegetation diversity in mountain peatland systems
(University of Waterloo, 2021-01-14)Mountain valley bottom peatlands are poorly studied systems, particularly in Alberta, Canada, where the provincial inventory has neither mapped nor characterized them. Nonetheless, these ecosystems provide valuable ecosystem ... -
Vegetation Response to Climate Change in North American National Parks: Policy & Management Implications
(University of Waterloo, 2008-01-28)Climate change is no longer debated in the context of whether or not it is occurring, but rather in the context of how rapid and extensive that change will be. This is the global situation to which the biomes of national ... -
Vehicle Battery Pack Design and Considerations for Repurposing
(University of Waterloo, 2015-09-28)The market for hybrid and electric vehicles is expanding with the rise of gas prices and desires to curb climate change. With the creation of these complex systems comes the development of advanced battery systems which ... -
Vehicle Dynamic and Control of Constrained Multi-Actuation Systems at the Limits of Handling
(University of Waterloo, 2021-03-17)With recent advances in electric vehicles, having electric motors directly driving the wheels is gaining attraction. When a vehicle is equipped with four independent electric hub motors or independently controlled brakes ... -
Vehicle Dynamic Modelling and Parameter Identification for an Autonomous Vehicle
(University of Waterloo, 2018-12-19)For autonomous vehicles to be feasible, a fast and accurate model of the vehicle dynamics is required due to the complexity of the task. There are many different aspects to a driverless vehicle, including path planning, ... -
Vehicle Lateral and Longitudinal Velocity Estimation Using Machine Learning Algorithms
(University of Waterloo, 2022-01-17)Prediction and estimation of states are of great importance for vehicle control and safety. The conventional observers are designed and used vastly in the automotive industry to fulfill this objective. However, the vehicle ... -
Vehicle Stability Control Considering the Driver-in-the-Loop
(University of Waterloo, 2016-08-04)A driver‐in‐the‐loop modeling framework is essential for a full analysis of vehicle stability systems. In theory, knowing the vehicle’s desired path (driver’s intention), the problem is reduced to a standard control ... -
Vehicle Tracking in Occlusion and Clutter
(University of Waterloo, 2008-01-08)Vehicle tracking in environments containing occlusion and clutter is an active research area. The problem of tracking vehicles through such environments presents a variety of challenges. These challenges include vehicle ... -
