SPS1.00001: A Low-Cost, Portable, Parallel Computing Cluster Daniel Bullock, Christian Poppeliers, Charles Allen Research in modern physical sciences has placed an increasing demand on computers for complex algorithms that push the limits of consumer personal computers. Parallel supercomputers are often required for large-scale algorithms, however the cost of these systems can be prohibitive. The purpose of this project is to construct a low-cost, portable, parallel computer system as an alternative to large-scale supercomputers, using Commercial Off The Shelf (COTS) components. These components can be networked together to allow processors to communicate with one another for faster computations. The overall design of this system is based on the development of ``Little Fe'' at Contra Costa College in San Pablo, California. Revisions to this design include improved design components, smaller physical size, easier transportation, less wiring, and a single AC power supply. [Preview Abstract] |

SPS1.00002: Crossing the Gender Gap: A Study of Female Participation and Performance in Advanced Maths and Sciences Jessica Haseltine A statistical analysis of enrollment in AP maths and sciences in the Abilene Independent School District, between 2000 and 2005, studied the relationship between gender, enrollment, and performance. Data suggested that mid-scoring females were less likely than their male counterparts to enroll in AP-level courses. AISD showed higher female : male score ratios than national and state averages but no improvement in enrollment comparisons. Several programs are suggested to improve both participation and performance of females in upper-level math and science courses. [Preview Abstract] |

SPS1.00003: RPC Detector Research and Development for PHENIX Austin Basye PHENIX, an experiment located on the RHIC ring at Brookhaven National Laboratory, is currently studying heavy ion collisions and polarized proton-proton collisions. To increase the effectiveness of the existing detector systems, Resistive Plate Chambers (RPCs) have been proposed for a level 1 trigger upgrade for the Muon Spectrometer Arms. These RPCs will improve W boson reconstructions from single high Pt muons by rejecting a large low Pt moun event background. This background will become larger as RHIC begins 500 Gev proton-proton collisions at higher luminosities. RPCs are currently being installed at all the major experiments at LHC, and it is from CMS, principally, that we have patterned the bulk of our design proposals. Based upon simulations, significant progress has been made to model signal pad layout, the mechanical structure and acceptance, and overcome design obstacles related to read-out and gas gap design.

SPS1.00004: Study of MgB2 superconductors using X-ray Diffraction, Electrical Resistivity, and Magnetization Measurements Cad Hoyt, Tsubasa Ito, Gan Liang X-ray diffraction (XRD, electrical resistivity, and magnetization measurements have been performed on some Ti-sheathed MgB2 superconducting wires which were sintered at different temperatures. By these measurements, we were able to identify the superconducting phase in these materials, obtain the values of the superconducting transition temperature, and study how the critical current density varies with the sintering temperature. We will discuss about these measurement techniques together with the measurement results on the Ti-sheathed MgB2 wires. [Preview Abstract] |

SPS1.00005: Measurement of Muon Anomalous Magnetic Moment C.S. Cowden, N. Akchurin The anomalous magnetic moment of cosmic muons are measured. The measurement is made by observing the decay positrons when the cosmic muon is stopped in an absorber held within a magnetic field (50 to 250 Gauss). Both the initial muon and the positron are detected by scintillation counters around the absorber and magnet assembly. The preliminary value of g=1.904 is obtained from a week's worth of data.

SPS1.00006: Nanoscience Professional Development Workshop for Science Teachers Vishal Kapoor, Eric Hagedorn Nanoscience Professional Development Workshop for Science Teachers This poster provides an overview of a 2 week nanoscience workshop for local high school and middle school science teachers. Goals, activities used, and evaluative findings are presented. [Preview Abstract] |

SPS1.00007: Computer Simulation of N-Body Interactions Curtis McCully, Nathaniel Troutman We set up a model universe consisting of N particles, whose interactions we can specify. With the equations of motion and the Euler-Cromer method to predict the next time step, so far we have simulated the dynamics of the present solar system on a millennial time scale. A work in progress, we have taken steps to create a simulation of Saturnian rings, solar system formation, and other systems. [Preview Abstract] |
