Robust Multi-Class Multi-Period Scheduling of MRI Services with Wait Time Targets
(University of Waterloo, 2018-01-23)In recent years, long wait times for healthcare services have become a challenge in most healthcare delivery systems in Canada. This issue becomes even more important when there are priorities in patients' treatment which ... -
Robust Nonlinear Model Predictive Control of Biosystems described by Dynamic Metabolic Flux Models
(University of Waterloo, 2019-05-13)The accuracy of the model used for prediction in Nonlinear Model Predictive Controller (NMPC) is one of the main factors affecting the closed loop performance. Since it is impossible to formulate a perfect model for a real ... -
Robust Nonlinear Model Predictive Control using Polynomial Chaos Expansions
(University of Waterloo, 2015-08-13)The performance of model predictive controllers (MPCs) is largely dependent on the accuracy of the model predictions as compared to the actual plant outputs. Irrespective of the model used, first-principles (FP) or empirical, ... -
A Robust Optimization Approach for Advance Scheduling in Health Care Systems with Demand Uncertainty: Policy Insights
(University of Waterloo, 2021-02-17)Patient wait times have increased significantly over the past few decades. According to the Canadian Institute for Health Information (CIHI), 40% of Canadians have experienced difficulties in receiving diagnostics tests. ... -
A Robust Optimization Approach to the Self-scheduling Problem Using Semidefinite Programming
(University of Waterloo, 2010-01-21)In deregulated electricity markets, generating companies submit energy bids which are derived from a self-schedule. In this thesis, we propose an improved semidefinite programming-based model for the self-scheduling problem. ... -
Robust Optimization for Airline Scheduling and Vehicle Routing
(University of Waterloo, 2014-12-03)Robust optimization is an emerging modeling approach to make decisions under uncertainty. It provides an alternative framework to stochastic optimization where operational parameters are random and do not assume any ... -
Robust Optimization for SCED in AC-HVDC Power Systems
(University of Waterloo, 2019-05-15)Wind power is a clean, renewable and low-carbon resource for power generation that has received increasing attention in power systems over the last few decades. There are two main challenges associated with the large-scale ... -
Robust Optimization of a Post-combustion CO2 Capture Absorber Column under Process Uncertainty
(University of Waterloo, 2019-02-07)In recent years, greenhouse gas (GHG) emissions is a global concern due to high concentrations of these gases in the atmosphere. Carbon capture and storage (CCS) has been suggested as an attractive alternative to curb ... -
Robust Sonographic Muscle Quality Assessment: A Live, Accurate Tissue Speed-of-Sound Estimation Framework
(University of Waterloo, 2024-02-23)Muscle quality can act as an indicator for physical health through qualitative – yet measurable – changes in muscle architecture and composition. One option for assessing muscle quality is through musculoskeletal ultrasound, ... -
Robust Spline Path Following for Redundant Mechanical Systems
(University of Waterloo, 2015-05-20)Path following controllers make the output of a control system approach and traverse a pre-specified path with no a priori time-parametrization. The first part of the thesis implements a path following controller for a ... -
Rock Stability under Different Fluid Flow Conditions
(University of Waterloo, 2003)It is widely known in oil industry that changes in fluid flow conditions such as water breakthrough or unsteady flow due to well shut-in can lead to sand destabilization, with a possible consequent sand production. In ... -
Rod Coating MoS2 Films and Silver Nanowire Electrodes for 2D Material-based Devices
(University of Waterloo, 2023-09-19)Two-dimensional materials have garnered significant attention in the research community due to their unique physical and electrical properties. Among these materials, molybdenum disulfide (MoS2) is a promising candidate ... -
The Role of Affect in Commercializing New Ideas
(University of Waterloo, 2008-07-22)Psychological attachment to an entrepreneurial opportunity may motivate the entrepreneur to persevere but can also bias decisions made in the entrepreneurial process, especially on market entry. This thesis investigates ... -
Role of Category Structure in Human Information Processing
(University of Waterloo, 2007-01-19)This investigation will use this ability in a different way. Studies have shown that a category can create a grade structure of prototypical items. We will take a graded structure generated by a category, and see if we can ... -
Role of Cryptographic Welch-Gong (WG-5) Stream Cipher in RFID Security
(University of Waterloo, 2012-05-23)The purpose of this thesis is to design a secure and optimized cryptographic stream cipher for passive type Radio Frequency Identification (RFID) tags. RFID technology is a wireless automatic tracking and identification ... -
The Role of Dominant Cause in Variation Reduction through Robust Parameter Design
(University of Waterloo, 2008-05-02)Reducing variation in key product features is a very important goal in process improvement. Finding and trying to control the cause(s) of variation is one way to reduce variability, but is not cost effective or even possible ... -
