Development of Ultrasonic Devices for Non-destructive Testing: Ultrasonic Vibro-tactile Sensor and FPGA-Based Research Platform
(University of Waterloo, 2020-04-29)This thesis is focused on the development of ultrasonic devices for industrial non-destructive testing (NDT). Ultrasound is generated from mechanical vibrations and then propagates through the medium. Ultrasonic devices ... -
Development of Unit Price Indices and Estimating Inflation for Potable Water and Wastewater Pipeline Capital Works Construction
(University of Waterloo, 2017-05-17)The importance of sustainable financial management of water and wastewater pipeline infrastructure has grown in recent years due to the increasing backlog of maintenance, renewal and replacement of aging water and wastewater ... -
Development of visual acuity and contrast sensitivity in children
(University of Waterloo, 2011-07-11)Purpose: There is little agreement on the age at which visual acuity (VA) and contrast sensitivity (CS) become adult-like. The ultimate purpose of this thesis was to determine whether VA and CS are adult-like at the age ... -
Development of Wastewater Collection Network Asset Database, Deterioration Models and Management Framework
(University of Waterloo, 2010-07-06)The dynamics around managing urban infrastructure are changing dramatically. Today’s infrastructure management challenges – in the wake of shrinking coffers and stricter stakeholders’ requirements – include finding better ... -
Development of Waterloo Robotic Rollator (WATRR)
(University of Waterloo, 2021-04-28)One of the major risk factors for impaired mobility is aging, and with the aging population on the rise, the demand for assistive technologies for individuals with mobility impairment is at an all time high. Impaired ... -
Development of weak cation exchange membrane adsorbers for protein capture
(University of Waterloo, 2015-09-21)To reduce therapeutic protein production costs in bioprocessing such as monoclonal antibodies production, the downstream purification step needs to be optimized. Protein A resins for the chromatographic purification of ... -
Development of wind resource assessment methods and application to the Waterloo region
(University of Waterloo, 2013-06-13)A wind resource assessment of two sites in the Waterloo region, WRESTRC and RIM Park, was conducted using wind speed, wind direction, temperature and pressure data collected from meteorological towers for over two years. ... -
Development of Zinc Oxide Nanowires and Quantum Dot Incorporation for Photovoltaic Applications
(University of Waterloo, 2016-01-18)Heterojunctions of metal oxide semiconductors with quantum dots (QD) have been deployed in a number of advanced electronic devices. Improvement in the devices’ performance requires in-depth studies on charge carrier transfer ... -
