Multi-scale Coherent Structure Extraction and Visualization for Flow Analysis
Coherent structures are important features in fluid flows. A better understanding of the physics of coherent structures will help explain a diverse range of physical phenomena and help improve our capability of modeling complex turbulence flows, such as those often seen in combustion, chemical …

Enriching Digital Maps with Aerial Imagery and GPS Data
… street maps consist of a collection of geometry structures such as a road graph and the semantics associated with the structures, such as the lane count and the speed limit of a road segment. This thesis first proposes two solutions, RoadRunner and Sat2Graph, to automatically extract road-level …

Extracting conceptual structures from multiple sources
This thesis extracts conceptual structures from multiple sources: Wordnet, Web Corpora and Wikipedia. The conceptual structures extracted from Wordnet and Web Corpora are inspired by the feature norm effort in cognitive psychology. The conceptual structure extracted from Wikipedia makes the …

Extracting and utilizing hidden structures in large datasets
The hidden structure within datasets --- capturing the inherent structure within the data not explicitly captured or encoded in the data format --- can often be automatically extracted and used to improve various data processing applications. Utilizing such hidden structure enables us to …

Vector-valued multidimensional signal processing and analysis in the context of fluid flows
… issue in this thesis is the analysis of vortex structures in turbulent fluid flows. A framework for identifying regions of vortices is established, which contains vortex structure modeling, pointwise linear approximation of flow fields, local fluid motion classification, and vortex structure …

Automated Building Information Extraction and Evaluation from High-resolution Remotely Sensed Data
… (2D) footprints and three-dimensional (3D) structures of buildings are of great importance to city planning, natural disaster management, and virtual environmental simulation. As traditional manual methodologies for collecting 2D and 3D building information are often both time consuming and …

Microstructure evolution and interconnect realiability
… of predicting the effects of geometry, microstructure, and processing conditions on electromigration (EM) induced interconnect failure, normal grain growth in thin films was studied, analytic models were built for the grain structure statistics in 2D and 3D interconnects, and simulation …
