Algorithms in Intersection Theory in the Plane
(University of Waterloo, 2023-06-02)This thesis presents an algorithm to find the local structure of intersections of plane curves. More precisely, we address the question of describing the scheme of the quotient ring of a bivariate zero-dimensional ideal ... -
Identifying Determinants of Performance for Females Completing a Paramedic Physical Employment Test
(University of Waterloo, 2023-06-02)Background: Sex disparities exist in employment and injury rates in the paramedic sector. Low success rates among females attempting physical employment standards could explain the elevated injury risk among female paramedics. ... -
On Nonlinear Time-Invariant Behavioural Models of Power Transistors Used in the Computer-Aided Design of Power Amplifiers
(University of Waterloo, 2023-06-01)The Radio Frequency (RF) Power Amplifier (PA) is the main consumer of power in a wireless transmitter. Energy efficient PA design aided with circuit simulation tools requires accurate nonlinear models of the power transistors ... -
Efficient Geo-Distributed Transaction Processing
(University of Waterloo, 2023-05-31)Distributed deterministic database systems support OLTP workloads over geo-replicated data. Providing these transactions with ACID guarantees requires a delay of multiple wide-area network (WAN) round trips of messaging ... -
Improving Cluster Scheduling Resiliency to Network Faults
(University of Waterloo, 2023-05-31)We present a comprehensive empirical study of the impact partial network partitions have on cluster managers in data analysis frameworks. Our study shows that modern scheduling approaches are vulnerable to partial network ... -
Children’s social perceptions and metaperceptions during an initial interaction with an unfamiliar peer
(University of Waterloo, 2023-05-31)Background. Interacting with an unfamiliar social partner is a critical first step in forming a relationship (Hinde & Stevenson-Hinde, 1987). During these initial interactions, individuals tend to be more positive than ... -
