Essays on Empirical likelihood for Heaviness Estimation, Outlier Detection and Clustering
(University of Waterloo, 2024-04-24)Empirical likelihood (EL) is a non-parametric likelihood method of inference. There are a large number of studies about the extensions and applications of EL. Most studies discuss the EL ratio for constructing confidence ... -
Evaluation of the Potential Impacts of Submerging the Oxidized Tailings and Adding a Cover Layer at Mine Principale
(University of Waterloo, 2024-04-24)Oxidation of sulfide minerals generates acid and forms various secondary phases including Fe(III) (oxy)hydroxide phases, jarosite, and gypsum, which can attenuate hazardous metal(loid)s by precipitation, co-precipitation, ... -
Advanced hybrid laser welding of pipeline steels using novel technologies
(University of Waterloo, 2024-04-23)Laser beam welding using a high energy density source is a promising method for joining thick plates due to its deep penetration and high productivity, although there are drawbacks such as poor gap-bridging ability, and ... -
Preference and Performance-Based Adaptive Task Planning in Human-Robot Collaboration
(University of Waterloo, 2024-04-23)This thesis delves into a central challenge in human-robot collaboration (HRC): the adaptive task planning of robots to enhance team performance, fluency, and the human agent's perception of both the robot and the ... -
Quantifying Human Mental States in Physical Human-Robot Interaction
(University of Waterloo, 2024-04-23)To support independent living among older adults, we propose the introduction of robots as domestic service providers capable of assisting with daily activities like showering, toileting, and transferring. These tasks ... -
Enhancing Real-Time Data Acquisition from Embedded Road Structural Health Monitoring Systems
(University of Waterloo, 2024-04-23)Canada's economy heavily relies on its roadways, yet managing pavement assets faces challenges due to past infrastructure spending cuts. Addressing this, a pavement management system (PMS) is essential for efficient resource ... -
Empirical Design Rules for Binder Jetting Additive Manufacturing
(University of Waterloo, 2024-04-23)Metal binder jetting additive manufacturing (BJAM) is an additive manufacturing (AM) process that builds parts from a feedstock metal powder material by spreading a layer of powder, then depositing liquid binder over the ... -
