Model-based Reinforcement Learning of Nonlinear Dynamical Systems
(University of Waterloo, 2022-01-25)Model-based Reinforcement Learning (MBRL) techniques accelerate the learning task by employing a transition model to make predictions. In this dissertation, we present novel techniques for online learning of unknown dynamics ... -
Modeling and simulation of uni- and multi-flagellar bacterial locomotion in a viscous fluid
(University of Waterloo, 2023-01-16)Flagellated bacteria categorized as microorganisms, play vital roles in human life such that their beneficial and detrimental effects on different aspects of the ecosystem are indisputable. Flagellated bacteria propel ... -
Modeling and Stabilizability of Voltage-Actuated Piezoelectric Beams with Magnetic Effects
(Society for Industrial and Applied Mathematics, 2014-01-01)Models for piezoelectric beams and structures with piezoelectric patches generally ignore magnetic effects. This is because the magnetic energy has a relatively small effect on the overall dynamics. Piezoelectric beam ... -
Modeling human-coupled common pool resource systems with techniques in evolutionary game theory and reinforcement learning
(University of Waterloo, 2021-05-26)Shared resource extraction among profit-seeking individuals involves a tension between individual benefit and the collective well-being represented by the persistence of the resource. In these systems, the decisions of ... -
Modeling Interactions of Graphene with Electrolyte in the Field-Effect Transistor Configuration
(University of Waterloo, 2015-08-14)Understanding interactions of graphene with an electrolyte is fundamental to its applications for chemical and biological sensors, where graphene operates in the configuration of a field-effect transistor with its surface ... -
The modeling of blood rheology in small vessels
(University of Waterloo, 2005)Blood is a dense suspension of flexible red blood cells. In response to a background flow, these cells distribute themselves non-uniformly throughout the vessel. As a result, material properties that are well defined ... -
Modeling of Brain Tumors: Effects of Microenvironment and Associated Therapeutic Strategies
(University of Waterloo, 2009-09-29)Gliomas are the most common and aggressive primary brain tumors. The most common treatment protocols for these brain tumors are combinations of surgery, chemotherapy and radiotherapy. However, even with the most aggressive ... -
Modeling of Cancer Signaling Pathways
(University of Waterloo, 2013-09-13)Cancer is an ongoing problem all over the world. To find a cure to this disease, both clinicians and scientists are looking for a reasonable treatment method. According to Hanahan and Weinberg, one of the hallmarks of ... -
Modeling Photoluminescence Decay Dynamics in Nanocrystals
(University of Waterloo, 2016-08-17)Photoluminescence resulting from donor-acceptor recombination in gallium oxide nanocrystals was studied at short and long time scales for different nanocrystal sizes. A model for the intensity decay was formulated with two ... -
Modelling Interactions Between Forest Pest Invasions And Human Decisions Regarding Firewood Transport Restrictions
(Public Library of Science, 2014-04-15)The invasion of nonnative, wood-boring insects such as the Asian longhorned beetle (A. glabripennis) and the emerald ash borer (A. planipennis) is a serious ecological and economic threat to Canadian deciduous and mixed-wood ... -
Modelling Internal Solitary Waves and the Alternative Ostrovsky Equation
(University of Waterloo, 2014-04-25)Internal solitary waves (ISWs) are commonly observed in the ocean, and they play important roles in many ways, such as transport of mass and various nutrients through propagation. The fluids considered in this thesis ... -
A modelling investigation into the impacts of the convective parameterization on the tropical circulation
(University of Waterloo, 2017-08-15)Many studies have shown that the tropical circulations (Walker and Hadley circulations) will weaken in a warmer world. This is sometimes attributed to changes in the tropical mean water cycling rate (driven by convective ... -
The Modelling of Biological Growth: a Pattern Theoretic Approach
(University of Waterloo, 2010-01-11)Mathematical and statistical modeling and analysis of biological growth using images collected over time are important for understanding of normal and abnormal development. In computational anatomy, changes in the shape ... -
Modelling resilience and sustainability of complex human-environment systems in agriculture and ecology
(University of Waterloo, 2020-06-01)As we move further into the Anthropocene, numerous challenges to sustainable development present themselves. Questions abound: How do we feed a growing population? What steps must we take to conserve ecologically valuable ... -
Modelling Science Trustworthiness Under Publish Or Perish Pressure
(Royal Society, The, 2018-01-01)Scientific publication is immensely important to the scientific endeavour. There is, however, concern that rewarding scientists chiefly on publication creates a perverse incentive, allowing careless and fraudulent conduct ... -
Modelling Subglacial Hydrology under Future Climate Scenarios in Wilkes Subglacial Basin, Antarctica
(University of Waterloo, 2022-10-21)The Greenland and Antarctic ice sheets have differing climates, which makes surface melt a significant hydrological source in Greenland but not currently in Antarctica. Due to a changing climate and warming air temperatures, ... -
Modelling the Subglacial Hydrology of Trinity-Wykeham Glaciers of the Northern Canadian Arctic
(University of Waterloo, 2023-11-09)In Canada’s High Arctic region, the melting of glacial ice contributes substantially to the world’s increasing sea levels (Harig and Simons, 2016). Of the icebergs in the region, approximately 62% are discharged by ... -
A modified sliding-mode observer design with application to diffusion equation
(Taylor and Francis, 2018-02-27)In many physical systems, the system's full state cannot be measured. An observer is designed to reconstruct the state from measurements. Disturbances often contribute to the dynamics of the system, and the designed observer ... -
