Exploring the Local Association : a nearby, young kinematic stream of stars in the solar neighborhood
(Vanderbilt University. Dept. of Physics & Astronomy, 2008)
During the course of my Honors Research Project, I worked with Dr. David
James to determine whether a group of target stars are members of the Local Association.
I did this by reducing spectroscopic data, taken by Dr. ...
Reflection and rotation for three dimensional microscopy of live cells
(Vanderbilt University. Dept. of Physics & Astronomy, 2008-04-18)
Confocal scanning laser microscopy and multiphoton microscopy provide 3D data from biological specimens, but with limited z-axis precision. Multiple microscale mirrors can be used to obtain more accurate 3D data on living ...
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. ...
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 ...
A Search for Pre-Main Sequence Eclipsing Binary Stars in the Lagoon Nebula
(Vanderbilt University. Dept. of Physics and Astronomy, 2009-04-20)
We report time-series CCD I-band photometry for the pre-main-sequence cluster NGC 6530, located within the Lagoon Nebula. The data were obtained with the 4Kx4K imager on the SMARTS 1.0m telescope at CTIO on 36 nights over ...
Measurement of Energy Spectrum of Electrons Field-Emitted from Diamond Field-Emitter Arrays
(Vanderbilt University. Dept. of Physics and Astronomy, 2009-04-20)
A retarding mesh analyzer was used to measure the electron energy spectrum field emitted from a single tip of a Diamond Field Emitter Array. The emission was dominated by adsorbed gas
atoms and molecules on the surface ...
Blazar Microvariations
(Vanderbilt University. Dept. of Physics and Astronomy, 2009-04-20)
In November 2006, the authors collected data on blazars PKS 0537-441, PKS
0447-439, and PKS 0208-5121 from the Cerra Tololo Inter-American Observatory in
Chile. All three blazars are tested for microvariability, first ...
