Fall 2011
This thesis studies the reinforcement learning and planning problems that are modeled by a discounted Markov Decision Process (MDP) with a large state space and finite action space. We follow the value-based approach in which a function approximator is used to estimate the optimal value function....

Regularization of the AVO inverse problem by means of a multivariate Cauchy probability distribution
DownloadSpring 2010
Amplitude Variation with O set (AVO) inversion is one of the techniques that is being used to estimate subsurface physical parameters such as P-wave velocity, S-wave velocity, and density or their attributes. AVO inversion is an ill-conditioned problem which has to be regularized in order to...

Fall 2009
A nonlinear finite element model was developed to study the behaviour of unstiffened steel plate shear walls. The model was validated using the results from quasi-static and dynamic experimental programs. With the validated finite element model, the performance of 4-storey and 8-storey Type D...

Fall 2011
The Applied Miniaturisation Laboratory (AML) has recently built a laser-induced fluorescent capillary electrophoresis (LIF-CE) genetic analysis instrument, called the Tricorder Tool Kit (TTK). By using a photodiode instead of photomultiplier tubes in the optical detection, the AML has lowered the...

Sparsity and Group Sparsity Constrained Inversion for Spectral Decomposition of Seismic Data
DownloadSpring 2012
Local time-frequency analysis, also known as spectral decomposition, allows for a more detailed interpretation of time-series by providing the evolution of the frequency spectrum through time and has proven to be a useful seismic attribute for exercises such as reservoir characterization. This...

System Level Monitoring for Time-Varying Conditions with Application to Ground Engaging Equipment
DownloadFall 2015
Condition monitoring is an effective tool for protecting equipment against unplanned and costly downtime. Conventionally, condition monitoring is only focused on the state of equipment's health and tracks the internal changes. However, more recent studies pointed out that an effective monitoring...

Historically seismic data processing has relied on the acoustic approximation to process single component data under the simplifying assumption that the recorded wavefield consists mainly of compressional wave modes. With the advancement of multicomponent seismic technology there is an increased...

Wave Speed Measurements of Grosmont Formation Carbonates: Implications for Time-Lapse Seismic Monitoring
DownloadFall 2019
The Grosmont Formation is a Devonian-aged carbonate platform complex that is estimated to hold over 64.5 billion m3 (406 billion bbl) of bitumen in place, accounting for a significant portion of Canada’s total hydrocarbon reserves. Despite this, the Grosmont formation has largely been undeveloped...
