(Vanderbilt University. Dept. of Physics and Astronomy, 2010-04-27)Current models of nuclear structure describe nuclear states in terms of collective vibrations and rotations of a ground state. - One such quadrupole vibrational band is the gamma-band formed by vibrations of the short ...
-
(Vanderbilt University. Dept. of Physics and Astronomy, 2010-04)Enclosed microfluidic devices provide excellent systems for the study of biological processes such as cell-cell, paracrine, and autocrine signaling systems. By minimizing the fluid volume within the chambers, ...

(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 ...
-
(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 ...

(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 ...
-
(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 ...
-
(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 ...

(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 ...
-
(Vanderbilt University. Dept. of Physics & Astronomy, 2008-04-27)Blazars AP Librae and 3c279 are analyzed for microvariability using a technique known as structure function analysis. AP Librae was observed in April of 2005 and 3c279 was observed in April of 2007. The data for AP Librae ...
-
(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 ...
-
(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 ...
-
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. ...
-
(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. ...
