Improving and Characterizing a High Resolution Spectrograph For Use in Measuring the Zeeman Effect in Mercury Gas Emission Lines
(2010-03-17)We have built and calibrated a high resolution spectrograph capable of resolving 0.024259±3.24x10−6 Angstroms per pixel. With several improvements to the instrument as well as extensive focusing, we have greatly increased ... -
Inertial Filtration of Lunar Dust in Lunar Gravity

Investigation of Propellant Sloshing and Zero Gravity Equilibrium for the Orion Service Module Propellant Tanks
(2012-08-09)We study fluid slosh in the Orion Service Module propellant tanks. Resonant slosh frequencies were measured as a function of tank fill-fraction in a scaled model of the tanks. We carry out both computational and theoretical ... -
Measuring the redshift evolution of Abell clusters and the density variation of the spiral to elliptical galaxy ratio in the Sloan Digital Sky Survey
(2010-03-18)From color photometry (Gunn ugr filter bands) of galaxies found in the Sloan Digital Sky Survey (SDSS) DR6 catalog, I have constructed color-color diagrams for 11 Abell galaxy clusters ranging in redshift from z=.018 to ... -
Modification and Reconstruction of Seismographs and Analysis of the Structure of Seismographs and the Local Seismic Activity in Southeastern Wisconsin
(2010-03-18)This project began with the reassembly of the Carthage College seismometers and en- hancing them to be more sensitive than they have been in the past. The potential seismic activity is collected as an electrical signal and ... -
Phase transitions in the Ising model with random gap defects using the Monte Carlo method
(2012-08-09)The Ising model, the simplest model of ferromagnetism, describes a magnetic lattice with nearest-neighbor interactions and is governed by Boltzmann statistics. The Monte Carlo method provides one approach to simulate ... -
Profiling the Acoustic Texture of Materials to Create Audio-Emulating Software: Preliminary Analysis
(2010-06-11)Acoustical effects can be created in the recording studio either authentically or by digitally emulating them over recorded sound. This paper provides preliminary analysis of sound data in the first step to creating a piece ... -
Repose Behavior of Lunar Simulants
(2010-06-11)Repose behavior for lunar simulants has been characterized using an experimental rig onboard the Zero-G Plane, a microgravity aircraft. Utilizing the continual motion of rotating drums, measurements of repose flow behavior ... -
Scaling and Modeling of Propellant Sloshing and Zero Gravity Equilibrium for the Orion Service Module Propellant Tanks
(2010-06-11)A scaled model of the downstream Orion service module propellant tank was constructed to assess the propellant dynamics under reduced and zero-gravity conditions. Flight and ground data from the experiment is currently ... -
Structural Analysis of NGC 2371-2 Using Deep Images in [O-III] and Tri-color
(2010-03-18)The odd structure of NGC 2371/2, a planetary nebula (PN) has been studied. This nebula has ejected gas during the final stages of stellar evolution. These gases do not appear to be symmetric as would be expected. Using a ... -
Theoretical Determination of the Radiation Pressure Inside of the NIF Hohlraum
(2010-03-17)The NIF facility was created to study fusion under controlled conditions. One hundred and ninety two of the world’s most powerful lasers are focused onto a very small gold cylindrical target. The high intensity laser heats ...
