Bicycle-Light Rail Transit Integration in Kitchener-Waterloo
(University of Waterloo, 2021-08-27)Active transportation, such as walking and cycling, are typically considered the first and last mile options for people who live close to transit corridors or transit hubs. Compared to walking, cycling allows faster travel ... -
Bidirectional Learning in Recurrent Neural Networks Using Equilibrium Propagation
(University of Waterloo, 2018-09-26)Neurobiologically-plausible learning algorithms for recurrent neural networks that can perform supervised learning are a neglected area of study. Equilibrium propagation is a recent synthesis of several ideas in biological ... -
Bidirectional mapping between self-consistent field theory and molecular dynamics
(AIP Publishing, 2007-10-08)A bidirectional mapping scheme that bridges particle-based and field-based descriptions for polymers is presented. Initial application is made to immiscible homopolymer blends. The forward mapping (upscaling) approach ... -
Bidirectional TopK Sparsification for Distributed Learning
(University of Waterloo, 2022-05-27)Training large neural networks requires a large amount of time. To speed up the process, distributed training is often used. One of the largest bottlenecks in distributed training is communicating gradients across different ... -
Bifocals in children with Down syndrome (BiDS)
(University of Waterloo, 2010-07-28)Down syndrome (DS) is the most common genetic cause of mental challenge in individuals and is associated with many ocular disorders. One of these anomalies which is frequently present in this population is reduced accommodation ... -
Bifunctionally active and durable hierarchically porous transition metal-based hybrid electrocatalyst for rechargeable metal-air batteries
(Elsevier, 2018-12-30)In this work, we show an effective strategy combining experimental and computational methods to explore and clarify rational design approaches utilizing transition metals for enhanced electrocatalysis of oxygen reactions. ... -
Bifurcation analysis and application for impulsive systems with delayed impulses
(World Scientific, 2017-11)In this article, we present a systematic approach to bifurcation analysis of impulsive systems with autonomous or periodic right-hand sides that may exhibit delayed impulse terms. Methods include Lyapunov–Schmidt reduction ... -
Bifurcation analysis of a system of Morris-Lecar neurons with time delayed gap junctional coupling
(University of Waterloo, 2008-08-27)We consider a system of two identical Morris-Lecar neurons coupled via electrical coupling. We focus our study on the effects that the coupling strength, γ , and the coupling time delay, τ , cause on the dynamics of the ... -
Bifurcation Analysis of Large Networks of Neurons
(University of Waterloo, 2015-12-23)The human brain contains on the order of a hundred billion neurons, each with several thousand synaptic connections. Computational neuroscience has successfully modeled both the individual neurons as various types of ... -
Bifurcation and Robust Control of Instabilities in the Presence of Uncertainties
(University of Waterloo, 2022-10-06)In real-world applications, nominal mathematical models that are used to describe the state behaviors of dynamical systems are usually less robust to deal with environmental disruptions. Uncertainties, such as imprecision ... -
Bifurcation of Bounded Solutions of Impulsive Differential Equations
(World Scientific Publishing, 2016-12-30)In this article, we examine nonautonomous bifurcation patterns in nonlinear systems of impulsive differential equations. The approach is based on Lyapunov–Schmidt reduction applied to the linearization of a particular ... -
Big Ships, Small Towns: The Impact of New Port Developments in the Cruise Tourism Industry. The case of Falmouth Jamaica
(University of Waterloo, 2013-06-18)ABSTRACT The cruise sector constitutes one of the fastest growing sectors of the tourism industry. With the continued growth of the industry comes the need to develop new ports to accommodate the increased volume of ... -
A Big Tiny Problem: Flows of Primary Microplastics in Canada
(University of Waterloo, 2023-08-31)Microplastics are ubiquitous across ecosystems, posing chemical and physical risks to wildlife and human health. To effectively monitor and manage the microplastics problem, a baseline of the mass of primary microplastics ... -
