Progress towards a quantum dot photovoltaic : nanocrystal deposition on structured titanium dioxide nanotubes
(Vanderbilt University. Dept. of Physics & Astronomy, 2008-04)
While this project did not successfully produce a working photovoltaic device, significant progress has been made in the individual components of the system. This thesis describes two of those components: fabrication of ...
Influence of patient size on dose to female breast tissue during routine computed tomography scans
(Vanderbilt University. Dept. of Physics & Astronomy, 2008-04-21)
Monte Carlo methods are well suited to the evaluation of radiation transport phenomena. The scalable phantoms employed in this project permitted rapid creation of three models of similar geometry, but different body habitus. ...
The search for M-M Dwarf Eclipsing Binary Systems
(Vanderbilt University. Dept. of Physics and Astronomy, 2016-05-18)
Using data from the Kilodegree Extremely Little Telescope (KELT) project,
we performed a survey of 2028 known M Dwarf stars in the KELT footprint
for M-M Dwarf eclipsing binaries (EBs). After searching 2028 Mdwarf ...
Number density profiles of galaxy groups and clusters in the SDSS
(Vanderbilt University. Dept. of Physics and Astronomy, 2008-04-20)
We use projected number density profiles of galaxy groups to investigate the relationship between galaxy group structure and dark matter structure within halos. We primarily study a specific model of how galaxies populate ...
Data Logistics and the CMS Analysis Model
(Vanderbilt University. Dept. of Physics and Astronomy, 2009-04-20)
The Compact Muon Solenoid Experiment (CMS) at the Large Hadron
Collider (LHC) at CERN has brilliant prospects for uncovering new
information about the physical structure of our universe. Soon
physicists around the world ...
Micro Programmable Object Navigation Gadget (micro-PONG) for Studying Electroosmotic Flow in PDMS Microchannel
(Vanderbilt University. Dept. of Physics and Astronomy, 2009-04-20)
Precise control of fluid delivery in analytical devices may be achieved by harnessing electroosmotic flow (EOF) in oxidized
poly(dimethylsiloxane) microfluidic channels fabricated via soft lithography. However, the ...
Engineering a perfusion-enabled mechanical compressor for long-duration immobilization and microscopy of cells and small organisms
(Vanderbilt University. Dept. of Physics and Astronomy, 2011-04)
The study of living specimens is essential to the understanding of
organismal behavior. Unfortunately, a major difficulty in the study of
live organisms is that many move in and out of the field of view or
focal plane ...
Perturbation Theory for Thin Cladding Layers on Silicon Photonic Systems
(Vanderbilt University. Dept. of Physics and Astronomy, 2011-04)
I develop a perturbation theory for resonant frequency shifts caused by thin
layer of material added to dielectric systems. This development can be used
to effectively model photonic surface-sensing systems, which use ...
Simulating the universe with GPU-accelerated supercomputers: n-body methods, tests, and examples
(Vanderbilt University. Department of Physics and Astronomy, 2013-04-22)
We demonstrate the acceleration obtained from using GPU/CPU hybrid clusters
and supercomputers for N-body simulations of gravity based in part on the
author's new code development. Validation tests are shown for ...
Real-time real-space density functional theory calculations of electron scattering in materials
(Vanderbilt University. Dept. of Physics and Astronomy, 2012-05-04)
Density functional theory is utilized in real-time,
real-space simulations of LEED measurements and attosecond electron
scattering. For LEED measurements, we find that our simulation results
agree well with experimental ...
