Scaling Permissioned Blockchains via Sharding
(University of Waterloo, 2023-01-25)Traditional distributed systems, such as those used in banking and real estate, require a trusted third party to operate and maintain them, which is highly dependent on the reliability of the operator. Since Bitcoin was ... -
Scalpel: Optimizing Query Streams Using Semantic Prefetching
(University of Waterloo, 2005)Client applications submit streams of relational queries to database servers. For simple requests, inter-process communication costs account for a significant portion of user-perceived latency. This trend increases ... -
Scan Registration Using the Normal Distributions Transform and Point Cloud Clustering Techniques
(University of Waterloo, 2013-04-23)As the capabilities of autonomous vehicles increase, their use in situations that are dangerous or dull for humans is becoming more popular. Autonomous systems are currently being used in several military and civilian ... -
Scanning Tunneling Microscopy of Electrically Driven Phase Transitions in a Charge Density Wave Material
(University of Waterloo, 2022-03-25)The 1T polytype of the van der Waals material TaS2, has been studied extensively as a strongly correlated system. Exhibiting several different charge density wave (CDW) states, the phase diagram of 1T-TaS2 has been explored ... -
Scared of compassion: Fear of compassion in anxiety, mood, and non-clinical groups
(British Psychological Society, 2020-05-04)Objectives. Fear of receiving compassion from others, expressing compassion to others, and being compassionate towards oneself have been identified as potentially important factors in the persistence of depression, stress ... -
Scarf's Theorem and Applications in Combinatorics
(University of Waterloo, 2006-12-19)A theorem due to Scarf in 1967 is examined in detail. Several versions of this theorem exist, some which appear at first unrelated. Two versions can be shown to be equivalent to a result due to Sperner in 1928: for a ... -
Scattering Equations and S-Matrices
(University of Waterloo, 2015-06-25)We introduce a new formulation for the tree-level S-matrix in theories of massless particles. Sitting at the core of this formulation are the scattering equations, which yield a map from the kinematics of a scattering ... -
Scenario Modeling and Execution for Simulation Testing of Automated-Driving Systems
(University of Waterloo, 2022-09-28)Automated Driving Systems (ADS) have the potential to significantly impact the future of ground mobility. However, safety assurance is still a major obstacle. Field testing alone is impractical and simulation is required ... -
Scene Representations for Generalizable Novel View Synthesis
(University of Waterloo, 2023-04-04)Novel view synthesis involves generating novel views of a scene when seen from different viewpoints. It offers numerous applications in computer vision domains such as telepresence, virtual reality, re-cinematography, etc. ... -
Scheduling in a Multi-Sector Wireless Cell
(University of Waterloo, 2009-10-29)In this thesis, we propose a scheduling problem for the downlink of a single cell system with multiple sectors. We formulate an optimization problem based on a generalized round robin scheme that aims at minimizing the ... -
Scheduling in Large Scale MIMO Downlink Systems
(University of Waterloo, 2008-04-16)This dissertation deals with the problem of scheduling in wireless MIMO (Multiple-Input Multiple-Output) downlink systems. The focus is on the large-scale systems when the number of subscribers is large. In part one, ... -
Scheduling in omnidirectional relay wireless networks
(University of Waterloo, 2013-09-25)The capacity of multiuser wireless network, unclear for many years, has always been a hot research topic. Many different operation schemes and coding techniques have been proposed to enlarge the achievable rate region. And ... -
Scheduling of Overload-Tolerant Computation and Multi-Mode Communication in Real-Time Systems
(University of Waterloo, 2014-12-10)Real-time tasks require sufficient resources to meet deadline constraints. A component should provision sufficient resources for its workloads consisting of tasks to meet their deadlines. Supply and demand bound functions ... -
Scheduling process operations under uncertainty and integration with long term planning
(University of Waterloo, 2022-09-22)This thesis centers upon the application of mathematical modelling, optimization theory and uncertainty analysis to the problem of scheduling batch operations for large scale industries. Over the years, decision making ... -
Scheduling Schemes using Connective Stability
(University of Waterloo, 2012-08-21)Large systems are often constructed using small subsystems which are connected. These interconnections can lead to complex behavior; for example, the entire system may become unstable even if each of the individual subsystems ... -
Schema clustering and retrieval for multi-domain pay-as-you-go data intergration systems
(University of Waterloo, 2010-07-08)A data integration system offers a single interface to multiple structured data sources. Many application contexts (e.g., searching structured data on the web) involve the integration of large numbers of structured data ... -
School Beverage Contracts & Childhood Obesity: A Case Study
(University of Waterloo, 2006)The objective of this study was to describe the issue of school beverage contracts and childhood obesity from the perspectives of a broad group of stakeholders. Specifically, the perspectives concerning contracts in two ... -
School start time changes in the COMPASS study: associations with youth sleep duration, physical activity, and screen time
(Elsevier, 2018-10-12)Background To date, no longitudinal population-based studies of school start times have been conducted within Canada. School schedule changes provided an opportunity to examine start times in association with youth sleep, ... -
