    • Investigating l-C3H2 as a Carrier for Diffuse Interstellar Bands 

      Troyer, Zachary; Dahlstrom, Julie (2011-09-02)
      Maier et al. has reported that the 4881 and 5450 ̊A diffuse interstellar band features may be associated with the compound C3H2 (l-C3H2) and the phase transition B1B1 ← X1A1. Here, we present evidence that l-C3H2 is in ...
    • Modal evaluation of fluid volume in spacecraft propellant tanks 

      Finnvik, Stephanie; Metallo, Steven; Robinson, John; Crosby, Kevin; Werlink, Rudy (2011-09-02)
      A novel, real-time method of determining the volume of propellant present in a spacecraft tank in reduced gravity is presented. In the experiment reported here, modal analysis techniques are applied to detect shifts in ...
