The Effect of Experience Upon the Visual and Haptic Discrimination of 3-D Object Shape
Both our sense of touch and our sense of vision allow us to perceive common object properties such as size, shape, and texture. The extent of this functional overlap has been studied in relation to infant perception (Bushnell & Weinberger, 1987; Gibson & Walker, 1984; Streri, 1987; Streri & Gentaz, …

Multiple region finite-difference time-domain modeling of duct cavities
… techniques are computationally efficient but often are inaccurate in predicting the RCS of cavities. This inaccuracy becomes particularly apparent when the wideband range resolved signature is desired. To overcome these limitations, this thesis investigates the possibility of modeling large …

Pipeline for semi-automatic segmentation of confluent endothelial cell membranes
… in cell morphology are important indicators of underlying biological changes. As endothelial cells (EC) heterogeneously respond to stimuli, we seek to quantify EC morphologic heterogeneity and relate it to transcriptome phenotypes; however, existing semi-automatic methods for quantifying cell …

The Universal Rotation Curve of Disk Galaxies
In the standard model of cosmology, the formation and evolution of dark matter halos plays an essential role in galaxy development. However, the response of the halo to internal baryonic processes is difficult to observe. We tackle this problem through an investigation of the Universal Rotation …

Inventorying trees in an urban landscape using small-footprint discrete return imaging lidar
Automation of urban tree inventory using remote sensing is needed not only to reduce inventory costs but also to support carbon accounting for urban planners and policy-makers. However, urban areas are heterogeneous and complex, and a more sophisticated approach is needed for using remote-sensing …

Improving Performance of Spatial Network Queries
… spatial network query algorithms rely on forms of network traversal which have a high complexity proportional to the size of the network making, them poor for large real-world networks. In this thesis, an alternative method of approximating the results of spatial network queries with a high …

Ab initio investigations of low Z materials under extreme conditions
… hydrogen and helium, make up the vast majority of matter in the universe. These elements are observed to exist over the widest known ranges of pressures and temperatures, from interstellar plasmas to the cores of stars. In modeling Jovian planets or inertial confinement fusion, the pressures and …
