NeuRA: Using Neural Networks to Improve WiFi Rate Adaptation
(University of Waterloo, 2020-09-04)Although a variety of rate adaptation algorithms have been proposed for 802.11 devices, sampling-based algorithms are preferred and used in practice because they only require frame loss information which is available on ... -
Neural correlates of trait anxiety in sensory processing and distractor filtering
(University of Waterloo, 2022-10-25)Anxiety, generally defined as an anticipatory heightened state of arousal, has been shown to affect neural markers of cognition and executive components used in sensorimotor function; however, this has infrequently been ... -
A neural model of the motor control system
(University of Waterloo, 2015-01-16)In this thesis I present the Recurrent Error-driven Adaptive Control Hierarchy (REACH); a large-scale spiking neuron model of the motor cortices and cerebellum of the motor control system. The REACH model consists of ... -
A neural modelling approach to investigating general intelligence
(University of Waterloo, 2010-08-06)One of the most well-respected and widely used tools in the study of general intelligence is the Raven's Progressive Matrices test, a nonverbal task wherein subjects must induce the rules that govern the patterns in an ... -
Neural modulation of the human visual cortex
(University of Waterloo, 2020-09-30)Neuroplasticity is a phenomenon that refers to the brain’s ability to reorganize, strengthen, and form neural connections, a process that becomes increasingly more difficult with age. Gamma amino-butyric acid (GABA), the ... -
Neural Network Classifiers for Human Tissue Classification in NIR Biomedical Multispectral Imaging
(University of Waterloo, 2018-06-11)Near infrared imaging (NIR) is an imaging modality that has gained traction for solving biomedical problems in recent years. By leveraging the NIR spectrum, multiple spectra from the NIR range can be used to extract ... -
Neural Network Viscosity Models for Multi-Component Liquid Mixtures
(University of Waterloo, 2009-08-31)An artificial neural network has been developed for the prediction of the kinematic viscosity of ternary, quaternary, and quinary systems. The systems investigated consisted of the following components: Heptane, Octane, ... -
Neural networks and quantum many-body physics: exploring reciprocal benefits.
(University of Waterloo, 2021-08-03)One of the main reasons why the physics of quantum many-body systems is hard lies in the curse of dimensionality: The number of states of such systems increases exponentially with the number of degrees of freedom ... -
Neural Plausibility of Bayesian Inference
(University of Waterloo, 2018-07-31)Behavioral studies have shown that humans account for uncertainty in a way that is nearly optimal in the Bayesian sense. Probabilistic models based on Bayes' theorem have been widely used for understanding human cognition, ... -
The Neural Processes of Perceived Simultaneity and Temporal Order in Younger and Older Adults using EEG.
(University of Waterloo, 2017-08-02)In order to make sense of the world, the central nervous system (CNS) must determine the temporal order of events and integrate cues that belong together. The process of integrating information from multiple sensory ... -
Neural Processing of Fearful and Happy Facial Expressions: Effects of Fixation to Facial Features and Task Demands
(University of Waterloo, 2015-11-25)The current literature regarding the time course of facial expression processing is inconsistent and early emotion effects are debated. Facial expressions are well-known to be characterized by “diagnostic” facial features ... -
Neural Text Generation from Structured and Unstructured Data
(University of Waterloo, 2019-08-28)A number of researchers have recently questioned the necessity of increasingly complex neural network (NN) architectures. In particular, several recent papers have shown that simpler, properly tuned models are at least ... -
Neural Tube Defect-causing Teratogens Affect Tissue Mechanical Properties and Cytoskeletal Morphology in Axolotl Embryos
(University of Waterloo, 2007-11-22)The teratogenic drugs cytochalasin B and valproic acid have been shown to alter F-actin polymerization, an effect that is crucial in forming microfilaments. Microfilaments form important cytoskeletal structures that maintain ... -
Neural-guidance for symbolic reasoning
(University of Waterloo, 2020-10-19)Symbolic reasoning begot Artificial Intelligence (AI). With the recent advances in Deep Learning, many traditional AI areas such as Computer Vision and Natural Language Processing have moved to probabilistic-based approaches. ... -
Neuregulin’s role in regulating the anti-inflammatory pathway
(University of Waterloo, 2009-08-12)Inflammation can be up-regulated by microglia and macrophages through the release of pro-inflammatory cytokines such as tumour necrosis factor-alpha (TNF-α). Excess production of TNF-α can lead to a variety of diseases and ... -
A Neurocomputational Model of Smooth Pursuit Control to Interact with the Real World
(University of Waterloo, 2014-01-24)Whether we want to drive a car, play a ball game, or even enjoy watching a flying bird, we need to track moving objects. This is possible via smooth pursuit eye movements (SPEMs), which maintain the image of the moving ... -
A neurocomputational model of the mammalian fear conditioning circuit
(University of Waterloo, 2013-09-24)In this thesis, I present a computational neural model that reproduces the high-level behavioural results of well-known fear conditioning experiments: first-order conditioning, second-order conditioning, sensory preconditioning, ... -
Neuromuscular Clinical Decision Support using Motor Unit Potentials Characterized by 'Pattern Discovery'
(University of Waterloo, 2009-01-21)Objectives: Based on the analysis of electromyographic (EMG) data muscles are often characterized as normal or affected by a neuromuscular disease process. A clinical decision support system (CDSS) for the electrophysiological ... -
Neuromuscular Control of Gait and Squatting Following a Simulated Occupational Kneeling Exposure
(University of Waterloo, 2016-01-20)Frequent and prolonged occupational high knee flexion postures such as kneeling and squatting are associated with an increased risk for the initiation and development of knee osteoarthritis. In order to reduce the prevalence ... -
Neurophysiological mechanisms of motor cortical modulation associated with bimanual movement
(University of Waterloo, 2008-09-11)The neural correlates of bilateral upper limb movement are poorly understood. It has been proposed that interhemispheric pathways contribute to the modulation of motor cortical excitability during bimanual movements, ...
