Multi-Resolution Approximate Inverses
(University of Waterloo, 1999)This thesis presents a new preconditioner for elliptic PDE problems on unstructured meshes. Using ideas from second generation wavelets, a multi-resolution basis is constructed to effectively compress the inverse of the ... -
Multi-resolution Image Segmentation using Geometric Active Contours
(University of Waterloo, 2004)Image segmentation is an important step in image processing, with many applications such as pattern recognition, object detection, and medical image analysis. It is a technique that separates objects of interests from ... -
Multi-resource Fair Scheduler in Linux
(University of Waterloo, 2022-09-29)Resource management is one of the main responsibilities of operating systems. In Linux, the Completely Fair Scheduler (CFS) allocates CPU time to processes, allowing them to share CPU time. Although effective in allocating ... -
Multi-robot Coverage and Redeployment Algorithms
(University of Waterloo, 2020-09-25)In this thesis, we focus on two classes of multi-robot task allocation and deployment problems motivated by applications in ride-sourcing transportation networks and service robots: 1) coverage control with multiple robots, ... -
Multi-Robot Path Planning for Persistent Monitoring in Stochastic and Adversarial Environments
(University of Waterloo, 2020-05-15)In this thesis, we study multi-robot path planning problems for persistent monitoring tasks. The goal of such persistent monitoring tasks is to deploy a team of cooperating mobile robots in an environment to continually ... -
A Multi-Scale Approach in Mapping the Sedimentological and Hydrostratigraphical Features of Complex Aquifers
(University of Waterloo, 2009-12-22)Accessibility to consistent subsurface hydrostratigraphic information is crucial for the development of robust groundwater flow and contaminant transport models. However, full three-dimensional understanding of the ... -
Multi-Scale Design of Ink Formulations for the 3D Bioprinting of Soft and Elastic Tissue-Mimetic Structures
(University of Waterloo, 2021-04-30)Three-dimensional (3D) engineered tissue and organ models with adjustable biochemical and physical properties are needed in regenerative medicine. As such, 3D printing has emerged as a potential strategy to create more ... -
Multi-scale habitat selection of land cover proportion by farmland birds in Ontario
(University of Waterloo, 2022-09-26)Modern agriculture is a central driver in species declines, and its harmonization with conservation is critical to achieving social and ecological sustainability. Due to agricultural land occupation and reduction of native ... -
A Multi-Scale Model for Nickel-Based Oxygen Carrier in Chemical-Looping Combustion
(University of Waterloo, 2019-07-19)The selection of oxygen carrier (OC) particles is crucial for the development of chemical-looping combustion (CLC) technology. Common OC particle models often involve first-order chemical reactions with respect to the ... -
Multi-scale Modeling and Optimization of Energy Absorption and Anisotropy in Aluminum Alloys
(University of Waterloo, 2017-04-26)This thesis outlines a study on the multi-scale modeling and optimization of lightweight aluminum front rails for automotive crashworthiness applications. This research is aimed to enhance the crashworthiness characteristics ... -
Multi-scale Modeling of Chemical Vapor Deposition: From Feature to Reactor Scale
(University of Waterloo, 2009-09-25)Multi-scale modeling of chemical vapor deposition (CVD) is a very broad topic because a large number of physical processes affect the quality and speed of film deposition. These processes have different length scales ... -
Multi-Scale Modeling of Laser Powder Bed Fusion Process for Superalloys
(University of Waterloo, 2022-12-02)Laser powder bed fusion (LPBF) is an additive manufacturing (AM) technique to fabricate complex geometries with minimal material waste. Over three hundred printing parameters can be altered to control the final part quality. ... -
Multi-scale Modelling of Oxygen Carriers in Chemical Looping Combustion Process
(University of Waterloo, 2021-01-08)Climate change is one of the major concerns affecting society. Given the severe effects of global warming, efficient CO2 capture and storage (CCS) technologies have become an urgent necessity. One of the major challenges ... -
Multi-scale Models of Tumor Growth and Invasion
(University of Waterloo, 2012-10-04)Cancer is a complex, multi-scale disease marked by unchecked cellular growth and proliferation. As a tumor grows, it is known to lose its capacity to maintain a compact structure. This stage of development, known as invasion, ... -
Multi-Scale Patterns of Eastern Milksnake (Lampropeltis triangulum) Habitat Selection and Behavioural Responses to Habitat Fragmentation
(University of Waterloo, 2018-05-09)The decline of species with specific habitat needs can be attributed to human caused habitat destruction and fragmentation. This is particularly concerning for reptiles, as they are often unable to adapt to modified ... -
