Beyond General Relativity: New Structure and Stability Predictions from Modified Gravity and High-Density Interaction Models
(University of Waterloo, 2022-09-29)In this thesis a number of topics are explored in an attempt to further understand gravitation and highly dense matter on a fundamental level. The notion of “quark stars” (QS), hypothetical compact stars composed of quark ... -
Evaluation of Laban Effort Features based on the Social Attributes and Personality of Domestic Service Robots
(University of Waterloo, 2022-09-29)Today, it is not uncommon to see robots adopted in various domains and environments. From manufacturing facilities to households, robots take over several roles and tasks. For instance, the adoption of robotic vacuum ... -
Multi-resource Fair Scheduler in Linux
(University of Waterloo, 2022-09-29)Resource management is one of the main responsibilities of operating systems. In Linux, the Completely Fair Scheduler (CFS) allocates CPU time to processes, allowing them to share CPU time. Although effective in allocating ... -
Fictitious Mean-field Reinforcement Learning for Distributed Load Balancing
(University of Waterloo, 2022-09-29)In this work, we study the application of multi-agent reinforcement learning (RL) in distributed systems. In particular, we consider a setting in which strategic clients compete over a set of heterogeneous servers. Each ... -
Studying and Leveraging API Usage Patterns
(University of Waterloo, 2022-09-29)Software projects make use of libraries extensively. Libraries have intended API surfaces—sets of exposed library interfaces that library developers expect clients to use. However, in practice, clients only use small ... -
Towards the Automation of Scalable Carbon Nanotube Sorting via Aqueous Two-Phase Extraction
(University of Waterloo, 2022-09-29)Carbon nanotubes are an exciting quantum material with numerous interesting and unique properties. Notable electric properties are their variable band-gap and metallic and semi- conducting variants. Carbon nanotubes are ... -
Consensus Problems in Hybrid Multi-Agent Systems
(University of Waterloo, 2022-09-28)A multi-agent system (MAS) is a dynamic system that consists of a group of interacting agents distributed over a network. In the past decades, the study of distributed coordination of multi-agent systems has been widely ... -
Video-Based Object Detection in Security Monitoring System
