    • Were ancient mesoamerican buildings oriented to magnetic north? 

      Carroll, Timothy John (Massachusetts Institute of Technology, 1979)
    • Wireless transfer of electric power 

      Moffatt, Robert Alexander (Massachusetts Institute of Technology, 2009)
      In this dissertation, I describe the design and construction of a system which can transfer electric power wirelessly. This is accomplished using inductive, near-field, non-radiative coupling between self-resonant copper ...
    • Wolter mirror microscope : novel neutron focussing and imaging optic 

      Bagdasarova, Yelena S. (Yelena Sergeyevna) (Massachusetts Institute of Technology, 2010)
      In this thesis, I investigated the effectiveness of a Wolter Type I neutron microscope as a focusing and imaging device for thermal and cold neutrons sources by simulating the performance of the optics in a standard neutron ...
    • X-ray periodicities in sources observed by the RXTE ASM 

      Shivamoggi, Vasudha B (Massachusetts Institute of Technology, 2005)
      The X-ray intensities measured from 230 X-ray sources observed by the RXTE All-Sky Monitor (ASM) were analyzed for periodic behavior. The ASM has been observing sources for nine years in the 1.5-12 keV energy range. In ...
    • X-ray power density spectra of black hole binaries : a new deadtime model for the RXTE PCA 

      Wei, Dennis (Massachusetts Institute of Technology, 2006)
      The power density spectrum is an essential tool for determining the frequency content of X-ray radiation from astronomical sources. For neutron star systems, power density spectra reveal coherent oscillations for those ...
    • Xmess--a graphical voice-mail interface 

      Berman, Lorne David (Massachusetts Institute of Technology, 1990)
    • Zero sound modes in the AdS/CFT correspondence 

      Roxlo, Thomas (Thomas Q.) (Massachusetts Institute of Technology, 2012)
      We examine the effects of zero sound wave excitations of charged fermion species living around the charged black hole of an AdS/CFT spacetime. In particular, we show that these bulk modes cause corresponding singularities ...
