The Rendered Body: Queer Utopian Thinking in Digital Embodiment
The rendered body is pure possibility, but it has been treated with an imaginatively limited lens that belies its potential for radical reimagining. I want to challenge those imaginative limits, especially in regard to gender and how gender is read on digital bodies. In order to do this, I will …

Numerical investigation of subsonic flow over bodies of revolution and a typical missile forebody
… to study the subsonic flow over a missile forebody. To this end, the NASA Ames developed OVERFLOW, three dimensional, Navier-Stokes Code was applied and detailed results were obtained for the missile forebody. The flow conditions were set at a Mach Number of 0.3 and Reynolds Number of two …

BEC-BCS crossover with Feshbach resonance for three-hyperfine-species model
… in the closed-channel. When the many-body energy scale (e.g. the Fermi energy, $E_{F}$) is larger than $\delta_c$, the closed-channel weight is significant and has to be included in the many-body theory. Furthermore, when two channels share a hyperfine species, the Pauli exclusion …

Casimir-Polder interaction in second quantization
… is to upgrade single-atom cQED with the many-body theory needed to describe trapped atomic BECs. Tools and methods are developed in a second-quantized picture that treats atom and photon fields on the same footing. We formulate a diagrammatic expansion using correlation functions for both the …

Effect of angular orientation on the hydrodynamic forces acting on a body in a restricted waterway
A slender body theory method developed for a body moving parallel to a wall in shallow water is extended to include angular orientation of the body to the wall. The method satisfies only the zero normal velocity condition on the external boundaries but does not take into account the effect of …

Vibration Based Planetary Gear Analysis and Damage Detection
… with different emphasizes on the rigid body simulation, the gained knowledge showed limitations of the rigid body model. Gear failures are very diverse and the actual simulation technique could not represent all necessary failure modes that can occur. That led to this thesis as a …

Quantum Interference Effects in Precision Spectroscopy of Helium Fine Structure
… provides a means of testing fundamental few-body theory as well as determining the fine-structure constant, which characterizes electromagnetic interactions in nature. Progress in both experiment and theory has led to increasingly precise values for the splittings between the n=2 triplet P …

Quasiparticle calculations in atoms and many-body core-valence partitioning
"The central work of this thesis is many-body Green's Function Method calculations in atoms using Hedin's GW approximation with various vertex corrections, leading to polarizabilities and quasiparticle energies, which are electron addition (removal) energies corresponding to the lowest few …

Desiccant dehumidification analysis
… operations of a unit. Based on the semi-infinite body theory, the semi-infinite model provides a way to simplify the solid-side diffusion resistance. A temperature control strategy is proposed to improve the mass transfer efficiency. A design in which the desiccant temperature is controlled in …

First-principles density functional theory study of sulfur oxide chemistry on transition metal surfaces
… via first-principles density functional theory (DFT) computations, focusing on the chemical reactivity and selectivity in sulfur poisoning chemical processes that address environmental concerns. The systematic approach we establish can be extended to general computational studies of small …

How the lived experiences of black women can be understood through devised theatre informed by psychophysical actor training: an adaptation of the Tadashi Suzuki actor training technique
In this study I aim to use my body as a tool to derive themes for use in performance making and to underpin this in theory. I focus on aspects of Tadashi Suzuki (1986) actor training (referred to as Suzuki training), free writing and the body. I use black feminism, cognitive neuroscience and body …

Vertical forces on the coupling of a pusher tug-barge
… solution method (unified slender body theory) is used to develop this interaction between the two hulls in coupled modes of motion at zero speed. Only the heave and pitch modes are considered. Experimental work was done on a coupled tug-barge model. The model was instrumented to …

Dynamic Self-Assembly of Magnetic Colloidal Particles
… coupled hydrodynamics that goes beyond slender body theory of the linked chains? This thesis answers the three questions and contributes to the understanding of colloidal dynamics and self-assembly in dynamic magnetic fields in the regime of high Mason numbers. We explore two aspects of the …

Swimming at low Reynolds number slip boundaries and interacting filaments
… subsequent work, I extend the classical slender-body theory to replace the no-slip boundary condition by a finite slip length. The second part of the thesis addresses the nature of hydrodynamic interactions between filaments - a phenomenon that occurs widely in the biological world. By developing …
