Biogeochemistry Across Spatiotemporal Scales: The Role of Reactive Interfaces in Modulating Landscape Scale Contaminant Fluxes
(University of Waterloo, 2022-09-09)The intensification of agricultural and urban activities has been accompanied by increased fluxes of nutrients to inland and coastal waters, leading to concerns of eutrophication and drinking water contamination. Certain ... -
Bioinformatic insights into the diversity and evolution of bacterial toxins
(University of Waterloo, 2020-01-24)Bacterial toxins are a broad category of molecules ranging from small organic compounds and peptides to large multi-domain or multi-meric enzymes. Several important diseases are caused primarily by bacterial toxins including ... -
Bioinformatic Insights into the Impacts of External Stimuli on the Human Airway
(University of Waterloo, 2021-12-21)The airway epithelium represents a critical component of the human lung that helps orchestrate defences against inhaled substances including air pollution, allergens, bacteria, and viruses. To manage these continuous ... -
Biointerface Topography for Enhanced Nonviral Gene Delivery
(University of Waterloo, 2023-12-11)Substrate-mediated nonviral gene delivery (SMD) represents a burgeoning area of interest in the field of tissue engineering due to its potential to facilitate localized transfection while providing the scaffolding for ... -
Biological Control of Disease Vectors: A Case Study Evaluating the Efficacy of Fathead Minnows (Pimephales promelas) for Mosquito Control in Northeast Wyoming
(University of Waterloo, 2016-01-12)West Nile virus (WNv) has become a significant and increasing threat to wildlife populations and human health throughout North America. Mosquito control is an important and potentially effective means of controlling the ... -
Biological Plausibility in Modern Hopfield Networks
(University of Waterloo, 2022-12-19)Modern Hopfield Networks (HNs) have the ability to store a large number of target memories (e.g. binary patterns) and then recall a memory in its entirety when prompted by a sub-set or perturbed version of it; in this ... -
Biological responses in rainbow darter (Etheostoma caeruleum) to changes in municipal wastewater quality in the Grand River
(University of Waterloo, 2017-09-27)This thesis is a synthesis of studies that explore the effects of urbanization on a small-bodied fish species, rainbow darter (Etheostoma caeruleum), in the central Grand River (Ontario, Canada) over time. This watershed ... -
Biologically Active Filtration Media Properties: Practical and Mechanistic Implications
(University of Waterloo, 2017-01-16)Biologically active filtration [BAF] can be used to concurrently remove particles and natural organic matter during drinking water treatment. The selection of a given media type for use in BAF can impact filter performance, ... -
Biologically Inspired Adaptive Control of Quadcopter Flight
(University of Waterloo, 2015-08-20)This thesis explores the application of a biologically inspired adaptive controller to quadcopter flight control. This begins with an introduction to modelling the dynamics of a quadcopter, followed by an overview of control ... -
Biologically inspired methods in speech recognition and synthesis: closing the loop
(University of Waterloo, 2016-02-18)Current state-of-the-art approaches to computational speech recognition and synthesis are based on statistical analyses of extremely large data sets. It is currently unknown how these methods relate to the methods that ... -
Biologically Inspired Spatial Representation
(University of Waterloo, 2020-10-08)In this thesis I explore a biologically inspired method of encoding continuous space within a population of neurons. This method provides an extension to the Semantic Pointer Architecture (SPA) to encompass Semantic Pointers ... -
Biologically Plausible Cortical Hierarchical-Classifier Circuit Extensions in Spiking Neurons
(University of Waterloo, 2018-01-09)Hierarchical categorization inter-leaved with sequence recognition of incoming stimuli in the mammalian brain is theorized to be performed by circuits composed of the thalamus and the six-layer cortex. Using these circuits, ... -
Biologically Plausible Neural Learning using Symmetric Predictive Estimators
(University of Waterloo, 2016-08-04)A predictive estimator (PE) is a neural microcircuit hypothesized to explain how the brain processes certain types of information. They participate in a hierarchy, passing predictions to lower layers, which send back ... -
Biologically Plausible, Human-scale Knowledge Representation
(University of Waterloo, 2014-08-22)Several approaches to implementing symbol-like representations in neurally plausible models have been proposed. These approaches include binding through synchrony, mesh binding, and tensor product binding. Recent theoretical ... -
