A Study of the Axial Crush Response of Hydroformed Aluminum Alloy Tubes
(University of Waterloo, 2007-12-03)There exists considerable motivation to reduce vehicle weight through the adoption of lightweight materials, such as aluminum alloys, while maintaining energy absorption and component integrity under crash conditions. To ... -
A Study of the Capabilities of Message-Oriented Middleware Systems
(University of Waterloo, 2023-01-27)We present a comprehensive characterization study of open-source Message-Oriented Middleware (MOM) systems. We devised a rigorous methodology to select and study 10 popular and diverse MOM systems. For each system, we ... -
A Study of the Detection of Defects in Ceramic Insulators Based on Radio Frequency Signatures.
(University of Waterloo, 2014-12-18)The presence of defects in outdoor insulators ultimately results in the initiation of partial discharge (PD) activity. Because insulation failure and the consequent breakdown of power equipment can occur due to the cumulative ... -
A Study of the Discursive Aspect of Scientific Theorizing and Modeling
(University of Waterloo, 2014-09-26)My dissertation contributes to the study of scientific theories and models by using a speech-act-theoretic framework to investigate the discursive aspect of theorizing and modeling practices. In the philosophical study of ... -
Study of the dynamic interactions between vergence and accommodation
(University of Waterloo, 2005)<em>Introduction:</em> Accommodation (change in ocular focus) and Vergence (change in ocular alignment) are two ocular motor systems that interact with each other to provide clear single binocular vision. While retinal ... -
Study of the effect of lateral inhomogeneities on the propagation of Rayleigh waves in an elastic medium
(University of Waterloo, 2006)The use of geophysical testing methods has considerable potential to be a cost effective and accurate technique to assess near-surface soil conditions. Multi channel analysis of surface waves (MASW) test is a geophysical ... -
A study of the effect of perturbations in spin ice systems: site dilution, weak exchange, quantum and finite-size effects
(University of Waterloo, 2014-08-20)In this thesis we investigate a range of properties for spin ice under various perturbations theoretically. Diluted spin ices, Dy2−x Yx Ti2 O7 and Ho2−x Yx Ti2 O7 , where the magnetic rare-earth ions Dy3+ and Ho3+ are ... -
Study of the Effects of Long Carbamate Chain on Indigoid-Based Donor-Acceptor Polymers for Organic Electronic Applications
(University of Waterloo, 2022-09-26)Novel donor-acceptor polymers based on indigoid building blocks, hemi-isoindigo and isoindigo, with the substitution of long carbamate side chains were synthesized for organic solar cells (OSCs) and organic field-effect ... -
A Study of the Effects of Solution and Process Parameters on the Electrospinning Process and Nanofibre Morphology
(University of Waterloo, 2011-08-31)Nanofibres have been the subject of recent intensive research due to their unique properties, especially their large surface-area-to-volume ratio, which is about one thousand times higher than that of a human hair. They ... -
A Study of the Electrical Flame Off Process During Thermosonic Wire Bonding with Novel Wire Materials
(University of Waterloo, 2010-04-30)Thermosonic ball bonding is the most popular method used to create electrical interconnects between integrated circuits (ICs) and substrates in the microelectronics industry. Traditionally gold (Au) wire is used, however ... -
A Study of the Erosion Mechanisms of Silicone Rubber Housing Composites
(University of Waterloo, 2014-04-23)Silicone rubber insulators have been replacing conventional insulators made from toughened glass and porcelain in the power system, due to the non-wetting properties of silicone rubber insulation housing. However, silicone ... -
