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 ... -
Biologically-inspired Motion Control for Kinematic Redundancy Resolution and Self-sensing Exploitation for Energy Conservation in Electromagnetic Devices
(University of Waterloo, 2014-01-07)This thesis investigates particular topics in advanced motion control of two distinct mechanical systems: human-like motion control of redundant robot manipulators and advanced sensing and control for energy-efficient ... -
Biomass Derived Laser-Induced Graphene with Embedded Catalysts: Towards Enhanced Oxygen Reduction Reaction Catalytic Performance
(University of Waterloo, 2023-06-21)Zinc-air batteries are viewed as one of the most promising energy storage technologies for consumer electronics, electric vehicles, and grid storage due to a number of benefits including relatively high theoretical specific ... -
BIOMECHANICAL ALTERATION OF CORNEAL MORPHOLOGY AFTER CORNEAL REFRACTIVE THERAPY
(University of Waterloo, 2006)<strong>Purpose:</strong> Although orthokeratology (non-surgical corneal reshaping, Corneal Refractive Therapy, CRT®) has been used for almost a half century, contemporary CRT's outcomes and mechanisms still require ... -
Biomechanical analysis of the pelvic floor and pessary device design
(University of Waterloo, 2023-11-21)Pelvic floor disorders (PFD) including pelvic organ prolapse (POP) can significantly impact women’s quality of life. Pessaries, removable gynecological prosthetic devices, provide mechanical support for temporary or long-term ... -
Biomechanical Assessment of Cycling Helmets: the Influence of Headform and Impact Velocity based on Cycling Collisions associated with Injury Claims
(University of Waterloo, 2015-01-23)The goal of my thesis was to fill some of the gaps in knowledge about cyclist/motor vehicle collisions and testing guidelines for cycling helmets. Cycling collisions with motor vehicles represent a problem for the Canadian ... -
A biomechanical investigation into the link between simulated job static strength and psychophysical strength: Do they share a “weakest link” relationship?
(University of Waterloo, 2011-01-17)Maximum voluntary forces and psychophysically acceptable forces are often used to set force guidelines for exertions as a means to protect against overexertion injuries in the workplace. The focus of this dissertation was ... -
Biomechanical Modelling of Paralympic Wheelchair Curling
(University of Waterloo, 2016-08-30)This research represents the first documented investigation into the biomechanics and neural motor control of Paralympic wheelchair curling. A multibody biomechanical model of the wheelchair curling delivery was developed ... -
Biomechanical Predictors of Functionally Induced Low Back Pain, Acute Response to Prolonged Standing Exposure, and Impact of a Stabilization-Based Clinical Exercise Intervention
(University of Waterloo, 2009-07-24)Purpose: Biomechanical differences between people with low back pain (LBP) and healthy controls have been shown previously. LBP has been associated with standing postures in occupational settings. A transient pain-generating ... -
A Biomechanical-Biochemical Hypothesis for the Role of Collagen in Injury
(University of Waterloo, 2022-07-25)Low back pain affects 80% of the population at some point in their lives and is the most common musculoskeletal complaint for workplace injuries. Further, it presents as episodic, with sufferers typically experiencing ... -
