Uncertainty quantification of unconventional reservoirs using assisted history matching methods
… characterization uncertainty. Assisted History Matching (AHM) methods provide attractive means for uncertainty quantification (UQ), because they yield an ensemble of qualifying models instead of a single candidate. Here we integrate embedded discrete fracture model (EDFM), one of …

New developments in causal inference using balance optimization subset selection
… These observational studies typically use matching methods which find matched pairs with similar covariate values. However, matching methods may not directly achieve covariate balance, a measure of matching effectiveness. As an alternative, the Balance Optimization Subset Selection (BOSS) …

Stereo Matching Based on Edge-Aware T-MST
Dense stereo matching is one of the most extensively investigated topics in computer vision, since it plays an important role in many applications such as 3D scene reconstruction. In this thesis, a novel dense stereo matching method is proposed based on edge-aware truncated minimum spanning tree …

Computer aided diagnosis of miliary TB in chest X-rays
… CAD of pulmonary miliary tuberculosis. Several methods for enhancing lung textures were discussed as an aid to the radiologist in diagnosing miliary TB. Some statistical approaches and template matching methods were used to measure characteristics of both healthy and unhealthy (miliary TB) lung …

Incremental object matching with probabilistic methods
This thesis deals with object matching, that is, the problem of locating the corresponding points of an object in an image. Conventional approaches to object matching are batch methods, meaning that the methods first learn the object model from a training set of example images that contain …

Towards Integrated Pixel Modelling
… re-formulation and extension of traditional mode-matching methods, and the development of the software package SCATTER-TNG (S-TNG) to incorporate them. The foundations of this software are built on the legacy of mode matching routines developed by the Terahertz Group at Maynooth University. This …

The Economic Impact of Wheelchairs for the Disabled in Ethiopia
… I demonstrate how nearest neighbor covariate matching methods can be used to estimate how wheelchair beneficiaries would have fared had they not been given a wheelchair. Results show that current wheelchair users earn $6.23 more per week, have a 15 percent higher probability of employment and …
