Mean field analysis gives accurate predictions of the behaviour of large networks of sparsely coupled and heterogeneous neurons
(BioMed Central, 2014-07-21)Large networks of integrate-and-fire (IF) model neurons are often used to simulate and study the behaviour of biologically realistic networks. However, to fully study the large network behaviour requires an exploration of ... -
Mean-field models for heterogeneous networks of two-dimensional integrate and fire neurons
(Frontiers Media, 2017-12-27)We analytically derive mean-field models for all-to-all coupled networks of heterogeneous, adapting, two-dimensional integrate and fire neurons. The class of models we consider includes the Izhikevich, adaptive exponential ... -
One-Dimensional Population Density Approaches To Recurrently Coupled Networks Of Neurons With Noise
(Society for Industrial and Applied Mathematics, 2015)Mean-field systems have been previously derived for networks of coupled, two-dimensional, integrate-and-fire neurons such as the Izhikevich, adapting exponential, and quartic integrate-and-fire, among others. Unfortunately, ... -
Nonsmooth Bifurcations of Mean Field Systems of Two-Dimensional Integrate and Fire Neurons
(Society for Industrial and Applied Mathematics, 2016)Mean field systems have recently been derived that adequately predict the behaviors of large networks of coupled integrate-and-fire neurons [W. Nicola and S.A. Campbell, J. Comput. Neurosci., 35 (2013), pp. 87-108]. The ... -
An Npz Model With State-Dependent Delay Due To Size-Structure In Juvenile Zooplankton
(Society for Industrial and Applied Mathematics, 2016)The study of planktonic ecosystems is important as they make up the bottom trophic levels of aquatic food webs. We study a closed nutrient-phytoplankton-zooplankton (NPZ) model that includes size structure in the juvenile ... -
Naive Bayes Data Complexity and Characterization of Optima of the Unsupervised Expected Likelihood
(University of Waterloo, 2017-09-21)The naive Bayes model is a simple model that has been used for many decades, often as a baseline, for both supervised and unsupervised learning. With a latent class variable it is one of the simplest latent variable models, ... -
Experimental prospects for detecting the quantum nature of spacetime
(University of Waterloo, 2017-09-21)This thesis is concerned with advancing the confrontation between relativistic quantum information (RQI) and experiment. We investigate the lessons that some present-day experiments can teach us about the relationship ... -
Landslide Hazard and Climate Change in the Mountain Glacial Environment of Northwest North America
(University of Waterloo, 2017-09-21)The aim of this thesis was to improve the understanding of the complex interactions between climate change and landslide behavior in the periglacial mountain environment of northwest North America. In particular, this ... -
Aging-related technologies: A multiple case study of innovation processes
(University of Waterloo, 2017-09-21)Introduction: As part of a Canadian research network focused on aging and technology – Aging Gracefully across Environments using technology to support Wellness, Engagement, and Long Life (AGE-WELL) – this thesis explored ... -
Prioritized Obstacle Avoidance in Motion Planning of Autonomous Vehicles
(University of Waterloo, 2017-09-21)Driver errors are a critical factor of the majority of car crashes. Autonomous vehicles take drivers and driver errors out of the equation, so they are being developed to reduce car crashes. However, in some situations, a ... -
Application of Textual Feature Extraction to Corporate Bankruptcy Risk Assessment
(University of Waterloo, 2017-09-21)The inception of the Internet in the late twentieth century has established the ability to generate a huge volume of data from multitudinous sources in a very short period of time. However, most of this data is presented ... -
Gender in The Generationed City: Current and Future Residential Location Preferences Among Young Adults
(University of Waterloo, 2017-09-21)This thesis contributes to a better understanding of how housing demand varies among young adults. Specifically, it explores gender differences in North American metropolitans and urban versus suburban residential locations ... -
"What the mind does not know, the eyes do not see": understanding the emerging health risk of food allergy in Ghana
(University of Waterloo, 2017-09-21)The epidemiologic transition demonstrates a relationship between infectious disease decline and the rise of chronic disease. In many developed countries, as rates of infectious disease fell from the 19th century, several ... -
Discovery of New Features for Peptide Sequencing with Mass Spectrometry
(University of Waterloo, 2017-09-21)Bioinformaticians have been working on peptide sequencing with tandem mass spectrometry (MS/MS) for decades. However, the results are still not perfect. A lot of research have been carried on two peptide sequencing methods, ... -
Cosmological Tests of Causal Set Phenomenology
(University of Waterloo, 2017-09-20)Causal Set Theory is an approach to Quantum Gravity that postulates that the fundamental structure of a spacetime manifold is a Lorentz Invariant discrete structure endowed with a causal order from which the geometry and ... -
On The Circuit Diameters of Some Combinatorial Polytopes
(University of Waterloo, 2017-09-20)The combinatorial diameter of a polytope P is the maximum value of a shortest path between two vertices of P, where the path uses the edges of P only. In contrast to the combinatorial diameter, the circuit diameter of P ... -
Smoking Cessation among Young Adult Dual Users of E-cigarettes and Tobacco Cigarettes in a Mobile Phone Intervention: Analysis of Data from a Randomized Controlled Trial
(University of Waterloo, 2017-09-20)Background Dual-use of electronic (e-cigarettes) and tobacco cigarettes has increased in the past few years (Czoli et al., 2015) without evidence of it being effective as a smoking cessation aid (Manzoli et al., 2015). ... -
Advanced non-precious metal catalyst for oxygen reduction reaction in polymer electrolyte membrane fuel cells
(University of Waterloo, 2017-09-20)To address the global energy and environmental challenges, the polymer electrolyte membrane fuel cell (PEMFC) is proposed and developed as one of the most promising power source candidates for various applications including ... -
Characterization of lambda systems using superconducting qubits
(University of Waterloo, 2017-09-20)Lambda systems, with a metastable state in addition to the ground state, naturally occur in many atomic systems. Atomic lambda systems offer many potential applications in quantum information processing including single ... -
