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 entropy analysis and Hurst exponent
(Elsevier, 2019-08-15)Several methods exist for measuring the complexity in a system through analysis of its associated time series. Multi-scale entropy appears as a successful method on this matter. It has been applied in many disciplines with ... -
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 CO2 capture: A Nickel-based oxygen carrier in Chemical-looping Combustion
(Elsevier, 2018-01-01)In this work, we present a multi-scale modelling framework for the Ni-based oxygen carrier (OC) particle that can explicitly account for the complex reaction mechanism taking place on the contacting surface between gas and ... -
A multi-scale model for coupling strands with shear-dependent liquid
(ACM, 2019-11)We propose a framework for simulating the complex dynamics of strands interacting with compressible, shear-dependent liquids, such as oil paint, mud, cream, melted chocolate, and pasta sauce. Our framework contains three ... -
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 ... -
A multi-scale model for simulating liquid-fabric interactions
(ACM, 2018-07)We propose a method for simulating the complex dynamics of partially and fully saturated woven and knit fabrics interacting with liquid, including the effects of buoyancy, nonlinear drag, pore (capillary) pressure, dripping, ... -
A Multi-scale Model for Simulating Liquid-hair Interactions
(Association for Computing Machinery, 2017-07-20)The diverse interactions between hair and liquid are complex and span multiple length scales, yet are central to the appearance of humans and animals in many situations. We therefore propose a novel multi-component simulation ... -
