Statistical Power in Ergonomic Intervention Studies
(University of Waterloo, 2010-04-21)As awareness of the costs of workplace injury and illness continues to grow, there has been an increased demand for effective ergonomic interventions to reduce the prevalence of musculoskeletal disorders (MSDs). The goal ... -
A Statistical Response to Challenges in Vast Portfolio Selection
(University of Waterloo, 2019-07-04)The thesis is written in response to emerging issues brought about by an increasing number of assets allocated in a portfolio and seeks answers to puzzling empirical findings in the portfolio management area. Over the ... -
Statistical Sample Size Determination Methods for Inspections of Engineering Systems
(University of Waterloo, 2018-12-18)A statistical sample size determination (SSD) method is designed for the maintenance of engineering components of similar structure within an overall system. The maintenance problem is defined as a sequential decision-making ... -
Statistical Techniques and Non-Destructive Testing Methods for Copper Wire Bond Reliability Investigation
(University of Waterloo, 2018-09-19)Microelectronic devices require packaging for mechanical protection and electrical interconnections. Reliability challenges in microelectronics packaging are becoming more severe, as applications demand smaller package ... -
Statistical Variability Analysis of SilGeo
(University of Waterloo, 2023-12-18)The electronics manufacturing and supply industry is rife with the unchecked circulation of counterfeit and tampered components. Although developments have been made to counter this issue, the methods often involve visual ... -
Statistical Yield Analysis and Design for Nanometer VLSI
(University of Waterloo, 2010-08-20)Process variability is the pivotal factor impacting the design of high yield integrated circuits and systems in deep sub-micron CMOS technologies. The electrical and physical properties of transistors and interconnects, ... -
A Statistically Rigorous Evaluation of the Cascade Bloom Filter for Distributed Access Enforcement in Role-Based Access Control (RBAC) Systems
(University of Waterloo, 2011-01-20)We consider the distributed access enforcement problem for Role-Based Access Control (RBAC) systems. Such enforcement has become important with RBAC’s increasing adoption, and the proliferation of data that needs to be ... -
Steady-State Analysis and Optimal Power Routing of Standalone Unbalanced Hybrid AC/DC Microgrids
(University of Waterloo, 2018-08-03)The concept of ac microgrids was introduced to integrate distributed generators (DGs) and loads within one entity that can operate autonomously or connected to a utility grid. Furthermore, dc microgrids have received ... -
Steam Gasification of Excavated Waste Residue (EWR) from a Landfill Bioreactor Operated Under cold Climate Conditions
(University of Waterloo, 2022-09-28)The use of fossil fuel to generate energy has contributed to the emission of greenhouse gases, which is a leading factor in the depletion of the ozone layer. This effect of fossil fuel on the atmosphere has led to the push ... -
Stearylated Peptides for Therapeutic siRNA Delivery and Their Cellular Uptake Mechanisms
(University of Waterloo, 2015-10-15)Small interfering RNA (siRNA) shows great potential as a powerful tool in gene therapy, due to its ability to regulate gene expression in a highly selective manner. siRNA is a double-stranded RNA consisting of 21–23 ... -
Steeltown Distilled: Extracting Hamilton's Latent Energies
(University of Waterloo, 2010-05-10)For one hundred years, the mighty blast furnaces of Stelco have burned, melted, and forged the identity of Hamilton, Ontario, into the epitomic Steeltown of Canada. Now US Steel Canada, its recently announced closure has ... -
Steering Clear of Cannabis: An Epidemiological Study of Traffic Violations among Emerging Adults who Engage in Regular or Occasional Use of Cannabis
(University of Waterloo, 2020-04-27)Background: A drug-impaired traffic violation is observed every three hours in Canada. Yet, there is conflicting evidence to suggest an increased risk of traffic violations in individuals who engage in cannabis use. ... -
The Steiner Ratio for the Obstacle-Avoiding Steiner Tree Problem
(University of Waterloo, 2008-09-26)This thesis examines the (geometric) Steiner tree problem: Given a set of points P in the plane, find a shortest tree interconnecting all points in P, with the possibility of adding points outside P, called the Steiner ... -
A step at a time: An investigation of preschoolers’ simulations of narrative events during story comprehension
(University of Waterloo, 2010-04-23)A growing body of work suggests that narrative comprehension involves the simulation of the events and actions described in a narrative (e.g., Barsalou, 2008; Matlock, 2004). Preliterate children’s ability to simulate a ... -
Step into the Void: A Study of Spatial Perception in Virtual Reality
(University of Waterloo, 2019-02-13)The introduction of virtual reality (VR) into the architectural profession offers an unprecedented opportunity to experience unbuilt designs at full scale. The premise of the technology is that it gives users the illusion ... -
A Step Towards Sustainable Transportation Behaviour: Understanding automobile ownership and mode choice through qualitative research
(University of Waterloo, 2007-09-27)It is now widely recognized that society’s over-reliance on the automobile contributes to environmental problems, especially in urban areas. Nevertheless, efforts to bring about modal shifts through transportation demand ... -
Stereocoherence thresholds as a measure of global stereopsis
(University of Waterloo, 2017-06-14)Purpose: The purpose of this study was to develop a robust and reliable clinical test of stereopsis that is complementary to the conventional disparity threshold tests. Methods: Random dot stereograms containing ... -
Still Wandering: Tales from the Diaspora
