Spatial Formation Control
(University of Waterloo, 2015-12-18)In this thesis, we study robust spatial formation control from several aspects. First, we study robust adaptive attitude synchronization for a network of rigid body agents using various attitude error functions defined on ... -
Spatial habit competes with effort to determine human spatial organization
(University of Waterloo, 2016-08-29)Despite the important role that the physical environment plays in shaping human cognition, few studies have endeavored to experimentally examine the principles underlying how individuals organize objects in their space. ... -
Spatial Modeling of Compact Polarimetric Synthetic Aperture Radar Imagery
(University of Waterloo, 2023-08-14)The RADARSAT Constellation Mission (RCM) utilizes compact polarimetric (CP) mode to provide data with varying resolutions, supporting a wide range of applications including oil spill detection, sea ice mapping, and land ... -
Spatial Patterns of Neighbourhood Crime in Canadian Cities: The Influence of Neighbourhood and City Contexts
(University of Waterloo, 2012-01-20)The main goal of this study is to investigate the spatial patterns of police-reported crime rates across select Canadian urban neighbourhoods and to explore their relationships with both neighbourhood- and city-level ... -
Spatial Patterns of Soil Organic Carbon Distribution in Canadian Forest Regions: An Eco-region Based Exploratory Analysis
(University of Waterloo, 2013-12-03)As the largest carbon reservoir in ecosystems, soil accounts for more than twice as much carbon storage as that of vegetation biomass or the atmosphere. The goal of this study is to examine spatial patterns of soil ... -
Spatial Patterns of Tree Invasion in an Old Field: Implications for Restoration
(University of Waterloo, 2008-05-08)In north-eastern North America, abandoned agricultural fields typically revert to forest after many decades of spontaneous succession. This process can be influenced in part by nearby available propagule sources and their ... -
Spatial Temperature and Concentration Changes Following Heterogeneous Damage To a Model Diesel Oxidation Catalyst
(University of Waterloo, 2010-12-02)Infra-Red thermography and spatially-resolved capillary inlet mass spectrometry (SpaciMS) have been used to characterize propylene oxidation along a Pt/Al2O3 monolith-supported catalyst, before and after heterogeneous ... -
Spatially and Temporally Resolving Concentration and Temperature Profiles within a Fresh and a Thermally-Aged Monolith Catalyst
(University of Waterloo, 2009-01-07)The ability to resolve reactions within a monolith spatially and temporally is key in developing reliable kinetic models, as well as in validating proposed reaction mechanisms. In this work, two techniques, IR-thermography ... -
Spatially Constrained Compound Magnification Framework for Histopathology Whole Slide Images
(University of Waterloo, 2022-09-14)Histopathology whole slide images (WSIs) contain a considerable amount of valuable information required for diagnosis, prognosis, and treatment planning. These scans are the product of a contemporary technology of ... -
A spatially explicit modelling approach for predicting and managing the effects of coral reef stressors
(University of Waterloo, 2022-09-09)Coral reefs represent simultaneously one of the most beloved and one of the most endangered ecosystems in the world. Millions of people visit coral reefs every year for tourism purposes, and millions of people living in ... -
Spatially Regularized Reconstruction of Fibre Orientation Distributions in the Presence of Isotropic Diffusion
(University of Waterloo, 2014-04-14)The connectivity and structural integrity of the white matter of the brain is known to be implicated in a wide range of brain-related diseases and injuries. However, it is only since the advent of diffusion magnetic resonance ... -
Spatially Regularized Spherical Reconstruction: A Cross-Domain Filtering Approach for HARDI Signals
(University of Waterloo, 2013-09-03)Despite the immense advances of science and medicine in recent years, several aspects regarding the physiology and the anatomy of the human brain are yet to be discovered and understood. A particularly challenging area in ... -
Spatially-Distributed Interactive Behaviour Generation for Architecture-Scale Systems Based on Reinforcement Learning
(University of Waterloo, 2020-02-18)This thesis is part of the research activities of the Living Architecture System Group (LASG). LASG develops immersive, interactive art sculptures combining concepts of architecture, art, and electronics which allow occupants ... -
A Spatio-Temporal Model for the Evaluation of Education Quality in Peru
(University of Waterloo, 2008-02-13)The role of information and communication technologies in the development of modern societies has continuously increased over the past several decades. In particular, recent unprecedented growth in use of the Internet in ... -
Spatio-Temporal Patterns in Net Anthropogenic Nitrogen and Phosphorus Inputs Across the Grand River Watershed
(University of Waterloo, 2016-09-23)Over the last century, human activities have dramatically increased the inputs of nitrogen (N) and phosphorus (P) to land, resulting in increased eutrophication of aquatic systems, and degradation of drinking water quality. ... -
