      Vibert, Michelle (University of Waterloo, 2010-06-17)
      BACKGROUND: Youth continue to be at high risk for STI and HIV transmission and unplanned pregnancies because of their liberal approach to sexual-health and their susceptibility toward engaging in risky activities. Youth ...
    • Safe, Quiet and Durable Pavement Surfaces 

      Ahammed, Mohammad Alauddin (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 ...
    • Safety Effects of Preventative Maintenace: Microsurfacing : A Case Study 

      Erwin, Tara Christine (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 ...
    • Sagging resistance of warm formed aluminum brazing sheet 

      Benoit, Michael J.; Kaur, R.; Wells, Mary; Jin, H.; Amirkhiz, B. Shalchi; Winkler, Sooky (Elsevier, 2018-04-01)
      Interrupted tensile tests, performed between room temperature (RT) and 250°C, were used to simulate warm forming of an AA3003/AA4045 brazing sheet. Brazing performance was predicted from sagging distance measurements after ...
    • Salacious Sade and Perverted Poe: Perversity and the quest for knowledge from 1740 to 1895 

      Baldwin, Brittney (University of Waterloo, 2014)
      The purpose of this thesis is to examine the role of perversity within the Self as a quest for individual knowledge. Libertine and Gothic literature will be characterized as an individualized reflection on society’s ...
    • The Saliva Exposome for Monitoring of Individuals’ Health Trajectories 

      Bessonneau, Vincent; Pawliszyn, Janusz; Rappaport, Stephen M. (Environmental Health Perspectives - United States Federal Government, 2017-07-20)
      Background: There is increasing evidence that environmental, rather than genetic, factors are the major causes of most chronic diseases. By measuring entire classes of chemicals in archived biospecimens, exposome-wide ...
    • Salt Mass Balance Study and Plant Physiological Responses for an Enhanced Salt Phytoremediation System 

      Zhong, Han (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 

      da Silva, Catia Marisa Costa (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 

      Thacher, Dana (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 and robust marginal methods for cluster-randomized trials with censored event times 

      Cook, Richard J.; Zhong, Yujie (Wiley, 2015-03-15)
      In cluster-randomized trials, intervention effects are often formulated by specifying marginal models, fitting them under a working independence assumption, and using robust variance estimates to address the association ...
    • Sample size effect in ultrasonic testing of geomaterials - numerical and experimental study 

      Berube, Simon (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 

      McCarthy, Philip James (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 

      Seifi, Seyed Mohammad Ehsan (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 Program Execution Monitoring 

      Ba, Yanmeng (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 

      Jones, Bryn (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 

      Jay, Andrew (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 

      Kwon, Tae-Jung (University of Waterloo, 2011-04-29)
