Spectrum Sensing in Cognitive Radio: Multi-detection Techniques based Model
(University of Waterloo, 2012-12-19)Cognitive radio (CR) paradigm is a new radio technology proposed to solve spectrum scarcity and underutilization. Central to CR is spectrum sensing (SS), which is responsible for detecting unoccupied frequencies. Since ... -
A Speculative Exploration into the Current Planning Paradigm through Academic Planner Perspectives
(University of Waterloo, 2023-09-28)This thesis centres on research aimed at understanding the essence of the current planning paradigm, identifying the factors that facilitate or hinder paradigm shifts, and determining the prevailing paradigm that governs ... -
Speech Endpoint Detection: An Image Segmentation Approach
(University of Waterloo, 2013-04-26)Speech Endpoint Detection, also known as Speech Segmentation, is an unsolved problem in speech processing that affects numerous applications including robust speech recognition. This task is not as trivial as it appears, ... -
Speed of Response does not Affect Feelings of Rightness in Reasoning
(University of Waterloo, 2019-09-18)It has been argued (Thompson, Prowse Turner & Pennycook, 2011) that the experience of ease (i.e., the ability to quickly generate an initial response) during processing influences one’s likelihood of engaging reflectively ... -
Spherical Silicon for Photovoltaic Application: Material, Modeling, and Devices
(University of Waterloo, 2008-01-21)Detailed material characterization of spherical silicon is conducted for the first time. Experimental results on crystallinity, impurities, and structural defects are presented to investigate the effect of growth mechanism ... -
Spherical Silicon Photovoltaics: Material Characterization and Novel Device Structure
(University of Waterloo, 2008-08-28)Single crystalline silicon spheres have been used as alternative material for solar cell fabrication. This innovative technology has several advantages over traditional wafer technology. However, the material, process ... -
Spherically Confined Polymers: Monte Carlo Simulations with Expanded Ensemble Density-of-States Method
(University of Waterloo, 2018-02-20)In this thesis, the Expanded Ensemble Density-of-States (EXEDOS) method - a combination of the Wang-Landau and Expanded Ensemble Monte Carlo algorithms is employed to investigate spatial conformations of a polymer chain ... -
SPIDER: Reconstructive Protein Homology Search with De Novo Sequencing Tags
(University of Waterloo, 2011-04-21)In the field of proteomic mass spectrometry, proteins can be sequenced by two independent yet complementary algorithms: de novo sequencing which uses no prior knowledge and database search which relies upon existing protein ... -
Spiking Deep Neural Networks: Engineered and Biological Approaches to Object Recognition
(University of Waterloo, 2018-01-08)Modern machine learning models are beginning to rival human performance on some realistic object recognition tasks, but we still lack a full understanding of how the human brain solves this same problem. This thesis combines ... -
A Spiking Neural Model of Episodic Memory Encoding and Replay in Hippocampus
(University of Waterloo, 2014-12-09)As we experience life, we are constantly creating new memories, and the hippocampus plays an important role in the formation and recall of these episodic memories. This thesis begins by describing the neural mechanisms ... -
A spiking neural network of state transition probabilities in model-based reinforcement learning
(University of Waterloo, 2017-10-23)The development of the field of reinforcement learning was based on psychological studies of the instrumental conditioning of humans and other animals. Recently, reinforcement learning algorithms have been applied to ... -
Spiking the Line: A Megaregional Growth Plan for the Windsor/Quebec Corridor
(University of Waterloo, 2010-01-22)In a truly global context, the contemporary urban landscape is changing dramatically. The megaregion has emerged as the primary scale of economic development and the home of the world’s wealth, innovation and progress. ... -
Spillover gentrification? Mid-sized cities within commuter sheds of global cities
(University of Waterloo, 2021-10-06)Commuter sheds have long comprised several mid-sized cities surrounding a large metropolis. The smaller cities typically feed into the economic and commuter orbit of the larger city. These ‘bedroom communities’ of the ... -
Spin-Preserving Metasurface-Based Focusing Mirror for Enhancing Light-Matter Interactions
(University of Waterloo, 2021-10-01)We propose a dielectric metasurface mirror that focuses one spin state while diverging the other state and preserves the spin state upon reflection, unlike conventional mirrors. First, we discuss the working principle of ... -
Spin-Spin Correlations in the CuAlCr₄S₈ Breathing Pyrochlore
(University of Waterloo, 2023-09-21)Frustrated magnetic systems, whose behaviour is influenced by competing interactions between magnetic spins, have been an active area of research. There is a special class of materials called breathing pyrochlores, whose ... -
