Performance Comparison Between Variable and Fixed Signature Codes in DS-CDMA Systems
(University of Waterloo, 2016-08-30)In a CDMA or SCMA system, users can use a fixed signature for the whole transmission interval. But there is the possibility for two users to have highly correlated signatures. Hence, high interference exists in the system, ... -
Performance Comparison of Large Diameter Residential Drinking Water Wells
(University of Waterloo, 2010-01-20)Published scientific work indicates that residential large diameter drinking water wells are at a higher risk of contamination from surface water impacts than drilled wells. The possibility of a higher incidence of ... -
Performance Comparison of Uniprocessor and Multiprocessor Web Server Architectures
(University of Waterloo, 2010-02-11)This thesis examines web-server architectures for static workloads on both uniprocessor and multiprocessor systems to determine the key factors affecting their performance. The architectures examined are event-driven ... -
A Performance Evaluation of Database Systems on Virtual Machines
(University of Waterloo, 2008-01-16)Virtual machine technologies offer simple and practical mechanisms to address many manageability problems in database systems. For example, these technologies allow for server consolidation, easier deployment, and more ... -

(University of Waterloo, 2023-11-28)The development of targeted drug delivery technologies to increase the specificity and efficacy of cancer treatments and reduce the reliance on systemic chemotherapy drugs have long been areas of research. Recent advances ... -
Performance Evaluation of Recycled Asphalt Shingles (RAS) in Hot Mix Asphalt (HMA): An Ontario Perspective
(University of Waterloo, 2011-04-12)Today, a large quantity of waste is generated from the replacement of residential and commercial roofs. Many of the roofs being upgraded with previously constructed from asphalt shingles. Recycled Asphalt Shingles (RAS) ... -
Performance Evaluation of Self-stabilizing Algorithms by Probabilistic Model Checking
(University of Waterloo, 2014-08-08)A self-stabilizing protocol is one that starting from any arbitrary initial state recovers to legitimate states in a finite number of steps, and once it stabilizes to a set of legitimate states, it remains there unless it ... -
Performance Evaluation of WiFi Backscatter Systems
(University of Waterloo, 2020-09-29)WiFi backscatter communication has been proposed to enable battery-free sensors to transmit data using WiFi networks. The main advantage of WiFi backscatter technologies over RFID is that data from their tags can be read ... -
Performance Improvement of an Optical Coherence Tomography System by use of an Optical Pupil Slicer
(University of Waterloo, 2011-04-08)Spectral domain optical coherence tomography (SD-OCT) is a dispersed interferometric technology used to obtain tomographic images, typically of tissue for medical applications. OCT is a competing technology with confocal ... -
