(University of Waterloo, 2021-09-16)As an Infrared detector with high responsivity, high transmission speed, and low dark current, InP/InGaAs p-i-n photodetectors (PD) have been used as a promising technology for many applications, including optical communication ... -
Investigation on Reaction Mechanisms of Nano-energetic Materials and Application in Joining
(University of Waterloo, 2019-01-23)Nano-energetic materials, also known as metastable intermetallic composites (MICs), have shown promise in applications such as propellants, pyrotechnics, and explosives. The work in this thesis pursues a deep understanding ... -
Investigation on the Compress-and-Forward Relay Scheme
(University of Waterloo, 2012-01-20)The relay channel plays an integral role in network communication systems. An intermediate node acts as a relay to facilitate the communication between the source and the destination. If the rate of codewords is less than ... -
Investigation on the Effects of Fastening Parameters on the Handle Displacement of a Pistol Grip Tool
(University of Waterloo, 2023-01-23)Workers in automotive assembly lines routinely use DC-powered pistol grip tools to install threaded fasteners. While these tools are easy to use and increase production quality, tool operators are subjected to impulsive ... -
Investigation on the implications of passive fire barriers on the fire fighting tactics of the Royal Canadian Navy
(University of Waterloo, 2022-03-28)The Royal Canadian Navy (RCN) is currently in the process of recapitalizing the fleet under the National Shipbuilding Strategy (NSS). This will result in a modern fleet that includes new marine safety requirements that did ... -
Investigation on using Supercritical Carbon Dioxide as Desorbing and Reaction Medium in the Surfactant Production Process
(University of Waterloo, 2007-05-22)To date, an estimated 70% of energy consumed comes from fossil fuels, such as coal, oil and natural gas. The major source of sulfur dioxide (SO2) emissions comes from combustion of these fossil fuels. Sulfur dioxide is a ... -
Investigations into Cellulolysis in Carbon Amended Tailings
(University of Waterloo, 2011-05-24)Modified cellulase enzyme assay methods were developed to determine the potential of using enzyme activities to evaluate the decomposition of organic matter in carbon amended mine tailings systems. Cellulase assays are ... -
Investigations into food web structure in the Beaufort Sea
(University of Waterloo, 2017-12-18)The effects of climate change on marine ecosystems are most pronounced in the Arctic, where ice free summers have been predicted to occur by mid-century. Climate-related changes to sea ice phenology, oceanographic habitat ... -
