Local nested transverse feedback linearization
(Springer, 2015-08-29)We study two local feedback equivalence problems for a nonlinear control-affine system with two nested, controlled-invariant, embedded submanifolds in its state space. The first, less restrictive, result gives necessary ... -
Local observers on linear Lie groups with linear estimation error dynamics
(IEEE, 2014-03-06)This technical note proposes local exponential observers for systems on linear Lie groups. We study two classes of systems. In the first class, the full state of the system evolves on a linear Lie group and is available ... -
Local Phase Coherence Measurement for Image Analysis and Processing
(University of Waterloo, 2013-04-25)The ability of humans to perceive significant pattern and structure of an image is something which humans take for granted. We can recognize objects and patterns independent of changes in image contrast and illumination. ... -
A Local Solution to the Output Regulation Problem for Sampled-Data Systems on Commutative Matrix Lie Groups
(IEEE, 2018-08-16)We present a smooth nonlinear control law for a kinematic plant on commutative matrix Lie groups that achieves regulation, if the state tracking and estimation errors are initialized in a suitable neighbourhood of identity. ... -
Local synchronization of sampled-data systems on one-parameter Lie subgroups
(IEEE, 2017-07-03)We present a distributed nonlinear control law for synchronization of identical agents on one-parameter Lie subgroups. If the agents are initialized sufficiently close to one another, then synchronization is achieved ... -
Local transverse feedback linearization for nested sets
(IEEE, 2016-02-11)We study a local feedback equivalence problem for a nonlinear control-affine system with two nested, controlled invariant, embedded submanifolds in its state space. The main result of this paper gives necessary and sufficient ... -
Log Event Filtering Using Clustering Techniques
(University of Waterloo, 2009-10-01)Large software systems are composed of various different run-time components, partner applications and, processes. When such systems operate they are monitored so that audits can be performed once a failure occurs or ... -
Logging Statements Analysis and Automation in Software Systems with Data Mining and Machine Learning Techniques
(University of Waterloo, 2022-01-19)Log files are widely used to record runtime information of software systems, such as the timestamp of an event, the name or ID of the component that generated the log, and parts of the state of a task execution. The rich ... -
Logical Superposition Coded Modulation for Wireless Video Multicasting
(University of Waterloo, 2009-04-23)This thesis documents the design of logical superposition coded (SPC) modulation for implementation in wireless video multicast systems, to tackle the issues caused by multi-user channel diversity, one of the legacy problems ... -
Long-Term Renewable Energy Generation Planning for Off-grid Remote Communities
(University of Waterloo, 2015-05-13)Electricity is widely seen as a flexible energy source that can potentially improve access to services and economic development in remote locations. Worldwide, there are 1.3 billion people without electricity access, out ... -
Long-Term Statistical Analysis and Operational Studies of Wind Generation Penetration in the Ontario Power System
(University of Waterloo, 2011-08-31)Ontario, as the rest of the world, is moving towards a clean energy sector and green economy and to this effect, the Government of Ontario has set a goal of phasing out all coal-fired generation by the end of the year 2014. ... -
Lossy Filter Synthesis
(University of Waterloo, 2013-09-26)All telecommunication systems, such as cellular mobile networks (cellphones), object-detection systems (radars), and navigation systems that include satellite positioning systems (GPS), base their functioning on radio wave ... -
Lossy Joint Source-Channel Coding for Energy Harvesting Communication Systems
(University of Waterloo, 2014-12-15)In this work, we study the problem of lossy joint source-channel coding in an energy harvesting single-user communication system with causal energy arrivals, where the energy storage unit may have leakage. In particular, ... -
