Controller and Observer Designs for Partial Differential-Algebraic Equations
(University of Waterloo, 2024-06-19)Partial differential-algebraic equations (PDAEs) arise in numerous situations, including the coupling between differential-algebraic equations (DAEs) and partial differential equations (PDEs). They also emerge from the ... -
Controller Design for Active Vibration Damping with Inertial Actuators
(University of Waterloo, 2019-05-06)In the machining industry, there is a constant need to improve productivity while maintaining required dimensional tolerances and surface quality. The self-excited vibration called chatter is one of the main factors limiting ... -
Controller Gain Optimization for Position Control of an SMA Wire
(University of Waterloo, 2007-05-17)There has been an increasing interest in the field of `smart structures' and `smart materials'. In constructing smart structures, a class of materials called smart materials are often used as sensors and actuators. An ... -
Controlling Cyberwarfare: International Laws of Armed Conflict and Human Rights in the Cyber Realm
(University of Waterloo, 2021-06-04)Cyberwarfare, military activities in cyberspace conducted by a state against another state and intended to disrupt or destroy computing or communication systems or data, is a recent addition to the warfaring arsenal. The ... -
Controlling deposition location in atmospheric-pressure spatial atomic layer deposition
(University of Waterloo, 2023-12-05)Nanoscale thin films exhibit unique properties and functionalities and are significant in a wide variety of applications and various sectors such as microelectronics, energy harvesting and storage applications, optoelectronics, ... -
Controlling Exciton Polarization in Transition Metal Doped Indium Oxide Nanocrystals
(University of Waterloo, 2024-02-20)The simultaneous manipulation of electronic charge and spin in dilute magnetic semiconductors (DMSs) doped with transition metal ions has been long considered a holy grail for advancing spintronics and quantum information ... -
Controlling Photon Emission from Nitrogen Vacancy Centers in Diamond
(University of Waterloo, 2021-04-16)In this thesis we investigate two domains of control over the photonic emission from NV centers. In the first part of the thesis, which focuses on emission control in the spatial domain, we will be exploring the design of ... -
Controlling Quantum Information Devices
(University of Waterloo, 2012-06-18)Quantum information and quantum computation are linked by a common mathematical and physical framework of quantum mechanics. The manipulation of the predicted dynamics and its optimization is known as quantum control. Many ... -
Controlling SALD-Deposited ZTO Nanofilm Composition and Implications for their use as Perovskite Solar Cell Transport Layers
(University of Waterloo, 2021-08-26)This thesis is concerned with the study of new nanofilm electron transport layers for use in perovskite solar cells, one of the thin film solar cell technologies in the research and very early commercial phases. Spatial ... -
Controlling the false discovery rate with dynamic adaptive procedures and of grouped hypotheses
(University of Waterloo, 2018-08-08)In the multiple testing problem with independent tests, the classical Benjamini-Hochberg (BH) procedure controls the false discovery rate (FDR) below the target FDR level. Adaptive procedures can improve power by ... -
Controlling the sustainability and shape change of the zinc anode in rechargeable aqueous Zn/LiMn2O4 battery
(Elsevier, 2018-11-01)The use of thixotropic gel electrolytes in the rechargeable hybrid aqueous battery improves the battery performance but it is required to have a corrosion inhibitor in the gel electrolyte. These inhibitors are not always ... -
Controlling the workload of M/G/1 queues via the q-policy
(Elsevier, 2015-06-01)We consider a single-server queueing system with Poisson arrivals and generally distributed service times. To systematically control the workload of the queue, we define for each busy period an associated timer process, ... -
Controlling “chemical nose” biosensor characteristics by modulating gold nanoparticle shape and concentration
(Elsevier, 2015-09)Conventional lock-and-key biosensors often only detect a single pathogen because they incorporate biomolecules with high specificity. “Chemical nose” biosensors are overcoming this limitation and identifying multiple ... -
Controls of Fish Mercury Concentrations in Subarctic Lakes of Canada
