Online Trace Reordering for Efficient Representation of Event Partial Orders
(University of Waterloo, 2012-01-20)Distributed and parallel applications not only have distributed state but are often inherently non-deterministic, making them significantly more challenging to monitor and debug. Additionally, a significant challenge ... -
OOMatch: Pattern Matching as Dispatch in Java
(University of Waterloo, 2007-09-11)We present a new language feature, specified as an extension to Java. The feature is a form of dispatch, which includes and subsumes multimethods, but which is not as powerful as general predicate dispatch. It is, however, ... -
Open Shortest Path First Routing Under Random Early Detection
(Wiley, 2018-03-01)In this article, we consider a variant of Open Shortest Path First (OSPF) routing that accounts for Random Early Detection (RED), an Active Queue Management method for backbone networks. In the version of OSPF we consider ... -
Open Source Software Evolution and Its Dynamics
(University of Waterloo, 2006)This thesis undertakes an empirical study of software evolution by analyzing open source software (OSS) systems. The main purpose is to aid in understanding OSS evolution. The work centers on collecting large quantities ... -
OpenBSD Hardware Sensors — Environmental Monitoring and Fan Control
(University of Waterloo, 2010-05-21)This thesis discusses the motivation, origin, history, design guidelines, API, the device drivers and userland utilities of the hardware sensors framework available in OpenBSD. The framework spans multiple utilities in ... -
Operator Spaces and Ideals in Fourier Algebras
(University of Waterloo, 2008-08-11)In this thesis we study ideals in the Fourier algebra, A(G), of a locally compact group G. For a locally compact abelian group G, necessary conditions for a closed ideal in A(G) to be weakly complemented are given, ... -
Operator Theoretic Methods in Nevanlinna-Pick Interpolation
(University of Waterloo, 2009-03-31)This Master's thesis will develops a modern approach to complex interpolation problems studied by Carath\'{e}odory, Nevanlinna, Pick, and Schur in the early $20^{th}$ century. The fundamental problem to solve is as follows: ... -
OPERATORS WHICH ARE POLYNOMIALLY ISOMETRIC TO A NORMAL OPERATOR
(American Mathematical Society, 2020-01-15)Let H be a complex, separable Hilbert space and B(H) denote the algebra of all bounded linear operators acting on H. Given a unitarily-invariant norm k · ku on B(H) and two linear operators A and B in B(H), we shall say ... -
Optimal Actuator Design for Nonlinear Systems
(University of Waterloo, 2019-09-24)For systems modeled by partial differential equations (PDE's), the location and shape of the actuators can be regarded as a design variable and included as part of the controller synthesis procedure. Optimal actuator ... -
Optimal Actuator Location for Semi-Linear Systems
(2018)Actuator location and design are important choices in controller design for distributed parameter systems. Semi-linear partial differential equations model a wide spectrum of physical systems with distributed parameters. ... -
Optimal Controller and Actuator Design for Nonlinear Parabolic Systems
(2019-10-08)Many physical systems are modeled by nonlinear parabolic differential equations, such as the Kuramoto-Sivashinsky (KS) equation. In this paper, the existence of a concurrent optimal controller and actuator design is ... -
Optimal Decumulation for Retirees using Tontines: a Dynamic Neural Network Based Approach
(University of Waterloo, 2023-09-19)We introduce a new approach for optimizing neural networks (NN) using data to solve a stochastic control problem with stochastic constraints. We utilize customized activation functions for the output layers of the NN, ... -
Optimal Direction-Dependent Path Planning for Autonomous Vehicles
(University of Waterloo, 2014-04-24)The focus of this thesis is optimal path planning. The path planning problem is posed as an optimal control problem, for which the viscosity solution to the static Hamilton-Jacobi-Bellman (HJB) equation is used to determine ... -
Optimal Dither and Noise Shaping in Image Processing
(University of Waterloo, 2008-08-20)Dithered quantization and noise shaping is well known in the audio community. The image processing community seems to be aware of this same theory only in bits and pieces, and frequently under conflicting terminology. ... -
Optimal Execution Strategies: A Computational Finance Approach
(University of Waterloo, 2015-01-27)In today's competitive business environment, strategies relating to market forecasting, decision making and risk management have received a lot of attention. The empirical results reveal that the market movement is not ... -
Optimal Experimental Design Applied to Models of Microbial Gene Regulation
(University of Waterloo, 2020-12-22)Microbial gene expression is a comparatively well understood process, but regulatory interactions between genes can give rise to complicated behaviours. Regulatory networks can exhibit strong context dependence, time-varying ... -
Optimal investment-reinsurance strategies with state dependent risk aversion and VaR constraints in correlated markets
(Elsevier, 2019-03)In this paper, we investigate the optimal time-consistent investment–reinsurance strategies for an insurer with state dependent risk aversion and Value-at-Risk (VaR) constraints. The insurer can purchase proportional ... -
Optimal Locations of Sensors and Actuators for Control of a Pedestrian Bridge
(University of Waterloo, 2021-12-22)Lightweight structures have been increasing in popularity in structural designs. However, they are more prone to disturbances. Therefore, a controller device can be placed on the structure to control the excessive vibrations. ... -
