Materializing the hole
This thesis concerns the body as it faces the computer. While it is informed by theories of embodiment, it argues against a retreat to the "human" in the face of new sensations that may result from the body's willing incorporation into the computer as an avatar. At the same time, the processes of …

Comparison Of Square-hole And Round-hole Film Cooling: A Computational Study
… to be protected. This injection is through holes that can have various shapes; simple shapes such as those with a straight circular (by drilling) or straight square (by EDM) cross-section are relatively easy and inexpensive to create. Immediately downstream of the exit of a film cooling …

Even-hole-free graphs
… class of simple graphs defined by excluding even holes (i.e. chordless cycles of even length). These graphs are known as even-hole-free graphs. We first prove that every even-hole-free graph has a node whose neighborhood is triangulated. This implies that in an even-hole-free graph, with n nodes …

Black Hole Accretion Systems
"Accretion onto a black hole is the most efficient known process to convert gravitational energy into radiation. Some gamma-ray bursts (GRBs), some X-ray binaries, and all active galactic nuclei (AGN) are likely powered by accretion onto a rotating black hole. I model the global, timedependent …

Rotating black hole spacetimes
… data sets represent distorted rotating black holes, and two types of non-rotating black holes with odd-parity radiation distortions. The first has the equatorial plane symmetry of the Kerr spacetime, the second has the equatorial plane symmetry of the ""cosmic screw"" spacetime."

Modeling the Dynamics of Black Hole Systems and the Ringdown of Black Hole Spacetimes
… observing gravitational waves from merging black holes in 2015, theoretical models had already been developed which would greatly contribute to the interpretation of that data. Thanks to numerical relativity, the merger of isolated near-equal mass ratio binary black holes, and the gravitational …

[W]hole: Journey to Fullness
<p>My work raises critical questions about Black history, race, gender, beauty, and privilege. My practice also highlights the intersectionality of colorism and racism. I use materials such as cardboard rectangles with handwritten words, brown paper, doors defaced by scratches, fire, printed …

Quantum properties of black hole
… the pressure inside the condensed black hole. It is found that the Bogoliubov dispersion relation for the elementary excitations of the weakly-interacting N-gravitons is shown to hold for the case of the weakly-interacting Graviton gas or N weakly interacting gravitons. where both the …

General Relativistic Black Hole-Neutron Star Simulations: Effects of Black Hole Spin and Binary Mass Ratio
… we simulate and compare them to binary black-hole waveforms. Only a small disk (< 0.01 M⊙ ) forms for the anti-aligned spin case (a/MBH = -0.5) and for the most extreme mass ratio case (q = 5). By contrast, a massive (Mdisk ≈ 0.2 M⊙ ), hot disk forms in the rapidly spinning (a/M …

Numerical relativity in black hole spacetimes
… the 3 + 1 numerical relativity study of black hole spacetimes. The main result of this thesis is the development of a new technique for avoiding singularities in such spacetimes. In this technique the slices are allowed to penetrate the black hole, but only the region of spacetime outside the …

An Exploration of Hole Filling Algorithms
… models. Previous research has shown that the hole filling step of the model creation pipeline is the primary cause of excess handles. We explore the hole filling process in detail and discuss the limits of hole fillers that work on the reconstructed surface and of those that work in the …

Nonlinear Waves on Extremal Black Hole Spacetimes
… condition on extremal Reissner-Nordstrom black hole spacetimes.Under the assumption of spherical symmetry I show that solutions which arise from sufficiently small compactly supported smooth data prescribed on a Cauchy hypersurface \widetilde{\Sigma}_0 crossing the future event horizon …

Semi-classical aspect of black hole physics
Semi-classical aspects of black hole physics are studied with particular emphasis on Hawking radiation and its derivation from tunnelling method techniques.

Numerical studies of Black Hole initial data
Diese Doktorarbeit behandelt neue Methoden der numerischen Evolution von Systemen mit binären Schwarzen Löchern. Wir analysieren und vergleichen Evolutionen von verschiedenen physikalisch motivierten Anfangsdaten und zeigen Resultate der ersten Evolution von so genannten 'Thin Sandwich' Daten, die …
