Ultrasound Imaging Innovations for Visualization and Quantification of Vascular Biomarkers
(University of Waterloo, 2019-09-03)The existence of plaque in the carotid arteries, which provide circulation to the brain, is a known risk for stroke and dementia. Alas, this risk factor is present in 25% of the adult population. Proper assessment of carotid ... -
Ultrasound-Induced Cavitation for Controlled Drug Release from Thermosensitive Liposomes
(University of Waterloo, 2022-05-02)Ultrasound-induced cavitation of microbubbles has increased anticancer drug Doxorubicin (DOX) release from thermosensitive liposomes (TSL). Yet, the influence of liposomal formulations and their responses toward cavitation ... -
Understanding and Generating Patches for Bugs Introduced by Third-party Library Upgrades
(University of Waterloo, 2017-12-20)During the process of software development, developers rely heavily on third-party libraries to enable functionalities and features in their projects. However, developers are faced with challenges of managing dependency ... -
Understanding Feedforward – Feedback Controller Components In Human Movement Through Optimization-Based Approaches
(University of Waterloo, 2023-04-10)Despite many studies in human motion analysis using optimal control theory to understand how movement is generated, less attention is focused on the structure of the optimal controller. The majority of existing studies ... -
Understanding Scalability Issues in Sharded Blockchains
(University of Waterloo, 2020-12-11)Since the release of Bitcoin in 2008, cryptocurrencies have attracted attention from academia, government, and enterprises. Blockchain, the backbone ledger in many cryptocurrencies, has shown its potential to be a data ... -
Unified Reliability Index Development for Utility Quality Assessment
(University of Waterloo, 2013-01-15)With the great potential smart distribution systems have to cause a paradigm shift in conventional distribution systems, many areas need investigation. Throughout the past few decades, many distribution systems reliability ... -
UniFlow: A CFG-Based Framework for Pluggable Type Checking and Type Inference
(University of Waterloo, 2023-04-21)A type system is a crucial component of high-level programming languages, as it enhances program correctness by ruling out certain type errors. However, the built-in type system often adheres to a specific set of rules ... -
Unipolar Charge-Sensing for Evaporated Large-Area Solid-State Photoconductors for Digital Radiography
(University of Waterloo, 2012-05-03)An alternative approach to energy integrating systems is photon counting which provides higher dose efficiency through efficient noise rejection and optimal energy weighting, and, moreover, is not susceptible to memory ... -
A Universal Islanding Detection Technique for Distributed Generation Using Pattern Recognition
(University of Waterloo, 2013-08-30)In the past, distribution systems were characterized by a unidirectional power flow where power flows from the main power generation units to consumers. However, with changes in power system regulation and increasing ... -
The UNIX Process Identity Crisis: A Standards-Driven Approach to Setuid
(University of Waterloo, 2014-11-03)This work revisits the setuid family of calls for privilege management that is implemented in several widely-used operating systems. Three of the four commonly used calls in the family are standardized by POSIX. The ... -
An Unsupervised Approach to Relatedness Analysis of Legal Language
(University of Waterloo, 2018-09-20)Learning distributed representations of sentences and analyzing semantic similarity between sentences is one of the essential works in the field of Natural Language Processing. In the domain of legal language, the future ... -
Upper Bounds to the Capacity of Wireless Networks
(University of Waterloo, 2008-05-16)In this thesis, I mainly focus on the evaluation of the upper bounds to the capacity of wireless networks. With the consideration of the two measures, the maximal transmission rate for any source-destination pair and the ... -
