Safe, Quiet and Durable Pavement Surfaces
(University of Waterloo, 2009-03-06)Skidding contributes to up to 35% of wet pavement accidents. Pavement surface friction therefore is an important component of highway safety. The skid resistance also varies seasonally and reduces over time due to surface ... -
SafeDS: Safe Data Structures for C++
(University of Waterloo, 2022-09-01)Memory corruption vulnerabilities in low-level languages such as C/C++ have been a problem in computer security for a long time. Accordingly, there has been a wide variety of proposed solutions for detecting or preventing ... -
Safety Effects of Preventative Maintenace: Microsurfacing : A Case Study
(University of Waterloo, 2007-09-19)Various North American transportation agencies have implemented several preventative maintenance techniques to improve pavement performance and safety. The Region of York, located north east of Toronto, Ontario, has been ... -
Safety-Critical Control for Dynamical Systems under Uncertainties
(University of Waterloo, 2024-02-15)Control barrier functions (CBFs) and higher-order control barrier functions (HOCBFs) have shown great success in addressing control problems with safety guarantees. These methods usually find the next safe control input ... -
Safety-Oriented Stability Biases for Continual Learning
(University of Waterloo, 2020-01-24)Continual learning is often confounded by “catastrophic forgetting” that prevents neural networks from learning tasks sequentially. In the case of real world classification systems that are safety-validated prior to ... -
Salinity Effects on Dissolved Organic Carbon Concentration and Quality in a Constructed Fen Peatland, Fort McMurray, AB
(University of Waterloo, 2020-08-05)In northern Alberta, oil sands mining disturbs the landscape; reclamation to an “equivalent land capability” is required, and industry is testing peatland construction as part of landscape reclamation. To determine if these ... -
Salt Mass Balance Study and Plant Physiological Responses for an Enhanced Salt Phytoremediation System
(University of Waterloo, 2011-07-11)Salinity is one of the most severe environmental factors that limits global crop yield. Enhanced phytoremediation using plant growth promoting rhizobacteria (PGPR) has proven to be an effective and environmentally responsible ... -
Salvage Montage
(University of Waterloo, 2009-09-09)This thesis proposes a reinterpretation of assumptions towards material value. It is a positive argument in favour of adaptive re-use, not only as a means to divert waste but also as encouragement to reconsider our current ... -
Salvaging on the Coast of Erebus Bay: An Analysis of Inuit Interaction with Material from the Franklin Expedition
(University of Waterloo, 2018-01-02)Over the course of the 19th century, many European explorers sailed in search of a Northwest Passage through the Canadian Arctic. These journeys brought them into territory occupied by Inuit, who both traded with the ... -
Sample size effect in ultrasonic testing of geomaterials - numerical and experimental study
(University of Waterloo, 2008-05-21)Nondestructive evaluation of civil structures is of increasing interest to utility owners. Several methods exist to evaluate different properties of concrete, pavement, cemented sands and others. UPVM is the most commonly ... -
Sampled-Data Control of Invariant Systems on Exponential Lie Groups
(University of Waterloo, 2019-08-28)This thesis examines the dynamics and control of a class of systems furnished by kinematic systems on exponential matrix Lie groups, when the plant evolves in continuous-time, but whose controller is implemented in ... -
Sampling Time Jitter
(University of Waterloo, 2013-01-23)Electrical systems which use voltage transitions to represent timing information suffer from a degrading phenomenon called timing jitter. Sampling time jitter is the deviation of sampling clock from its ideal position. As ... -
Sampling-based Predictive Database Buffer Management
(University of Waterloo, 2023-09-25)This thesis presents a database buffer caching policy that uses information about long- running scans to estimate future accesses. These estimates are used to approximate the optimal caching policy, which requires knowledge ... -
Sampling-based Program Execution Monitoring
(University of Waterloo, 2010-08-30)For its high overall cost during product development, program debugging is an important aspect of system development. Debugging is a hard and complex activity, especially in time-sensitive systems which have limited ... -
Sampling-Window Based Approach for Fire Gas Analysis of Rigid Foams
(University of Waterloo, 2013-08-22)A sampling-window based approach was developed to collect and analyze the gases evolved during fire performance testing using the cone calorimeter. For this purpose, a Fourier Transform Intra-red (FTIR) Spectroscopy system ... -
Santa Claus, Machine Scheduling and Bipartite Hypergraphs
(University of Waterloo, 2020-01-10)Here we discuss two related discrete optimization problems, a prominent problem in scheduling theory, makespan minimization on unrelated parallel machines, and the other a fair allocation problem, the Santa Claus problem. ... -
SAR Remote Sensing of Canadian Coastal Waters using Total Variation Optimization Segmentation Approaches
(University of Waterloo, 2011-04-29)The synthetic aperture radar (SAR) onboard Earth observing satellites has been acknowledged as an integral tool for many applications in monitoring the marine environment. Some of these applications include regional sea-ice ... -
Satellite Dynamics in Dark Matter Halos
(University of Waterloo, 2010-09-01)I have used an analytic model of tidal interactions to predict the evolution of a substructure in a static dark matter halo. Given the initial conditions of the satellite and background halo, the model predicts with high ... -
Satellite observations of lake surface state to improve weather forecasting in a lake-rich region
(University of Waterloo, 2015-04-30)The thermal and dynamic properties of water bodies are important factors affecting the structure of the atmospheric boundary layer which stores and transports energy and mass. The storage and heat transfer of lakes play ... -
Satellite remote sensing observations of snow cover extent during the melt-out season in the Thompson-Okanagan Region, British Columbia from 2003-2019
(University of Waterloo, 2021-05-31)Snow is a critical component of the earth’s overall energy budget and it contributes significantly to water resources especially in mountainous regions, coining the term the “water towers” for downstream communities (Viviroli ...
