1 Hanes, Josh T.A comparison of nuclear thermal rockets with traditional chemical rockets for space transportThe Solar System has multiple destinations that private and governmental space agencies are planning to explore. Missions within the Solar System are both exorbitantly expensive and time intensive projects that involve high risks for the organizations involved. A mission that is currently being...Nuclear rockets - research; space vehicles - design - research; nuclear thermal rockets; chemical rockets; space transport2016-04
2 Lee, Charles Chang SukA demonstration apparatus for optical pumping of rubidiumOptical pumping refers to the use of light in order to elevate ("pump") the spin (intrinsic angular momentum) of an atom or molecule. This process is of interest from a pedagogical and experimental perspective because it encapsulates fundamental properties of atomic physics and quantum mechanics. Fu...Optical pumping -- Research Spin exchange -- Research Rubidium isotopes -- Research2015-05
3 Simon, Philip C.A study of the optimized load of a traveling wave thermoacoustic heat engineThermal interaction between differentially heated solid material and ambient gas in a resonator can lead to self-sustained oscillations or the transportation of heat in accordance with the thermoacoustic effect, first explained by Lord Rayleigh. In this research the phenomenon is employed in a lo...Thermoacoustic engine - Research; Energy conservation2016-03
4 Renz, AndyAssessment of exercise-stimulated tissue oxygenation in calf muscle with functional MRIPeripheral artery disease (PAD) affects millions of patients in the USA, and effective diagnosis and management of PAD is a major clinical goal. One promising avenue of research towards the goal is through functional MRI, which provides non-invasive measurement of tissue oxygenation. For a group of ...Arteries - Diseases - Diagnosis; Magnetic resonance imaging - Research; Calf muscle; Peripheral arterial disease; MATLAB2016-04
5 Christensen, MasenCooperative primers: Intersecting spherical model for optimization of linker and gap lengthsDetection of specific sequences of DNA is invaluable for diagnosing the presence of a pathogen, as well as other areas of genetic analysis. A common way of detecting DNA is replicating it millions of times through Polymerase Chain Reaction (PCR) and using fluorescent molecules to detect those copies...Pathogenic microorganisms - Detection; DNA - Research; Polymerase chain reaction - Research; Cooperative primers; Aluminum foam materials; Load frame2016-05
6 Garcia, Anthony D.Exploring galactic chemical abundance of phosphorus in the ultra-violet with HSTUltra violet observed spectral data taken by the Hubble Space Telescope (HST) are made available to the public. These data sets have been extracted into one-dimensional and flux-calibrated spectral data, and are ready for analysis. We have normalized the extracted spectra with a Planck black body cu...Milky Way - Phosphorus content2014-05
7 Johnston, Jessica FaithFrom nanoscience to astrophysics: using high-resolution microscopy and spectroscopy of carbonaceous chondrites to understand planet formationIn the field of astrophysics, there currently exists an outstanding gap of knowledge in understanding planet formation dynamics. At the formation scale ranging from millimeters to meters, astrophysicists debate as to how solar nebulae form larger masses-planets and other kilometer-sized bodies-from ...Physics & Astronomy2012-05
8 Wallace, Joshua J.Lyman-alpha emission as a probe of galaxy environmentsAs a result of resonant scatterings off hydrogen atoms, Lya emission from star-forming galaxies provides a potential probe of the neutral gas environment around them. In order to determine the utility of Lya emission as a probe of gas environments we study the effects of environmental anisotropy on ...Galaxies - Spectra2014-05
9 Rou, JanvidaMonte-Carlo simulation of stellar intensity interferometryStellar intensity interferometers will allow for achieving stellar imaging with a tenth of a milli-arcsecond resolution in the optical band by taking advantage of the large light collecting area and broad range of inter-telescope distances offered by future gamma-ray Air Cherenkov Telescope (ACT) ar...Monte Carlo simulation2012-05
10 Fullmer, Alexander T.Optimization of gamma/hadron separation under variable source intensities and energy spectraThe High Altitude Water Cherenkov (HAWC) gamma-ray observatory consists of an array of water Cherenkov tanks that can detect extensive air showers (EAS) generated by astrophysical cosmic rays and gamma rays. One of the greatest challenges in using the HAWC observatory to search for astrophysical gam...Gamma ra sources - Observations; Cosmic rays - Observations; Gamma ray astronomy - Research2014-05
11 Hales, LaurelPhysics show and tell and elementary science educationIt is a well-known fact that American children are performing below their peers in international science and mathematics examinations, leading to what is commonly called the STEM education crisis. This project was created in an attempt to resolve this crisis by improving elementary school science ed...Science - Study and teaching (Elementary) - United States2014-05
12 Gregersen, DylanSearching for extragalactic stars among candidate halo moving clustersWe seek to identify stars accreted into the Milky Way which are remnants of its merging with smaller galaxies or star clusters. In our approach, we selected stars from candidate moving clusters in the Milky Way's Halo. These stars were grouped by similar stellar characteristics: orbital energy, orbi...Halo stars; Extragalactic origins; Milky Way2012-05
