    • Astronaut adaptive arm motions on the MIR Space Station : kinematic analysis 

      Thibault, Karen (Karen Camille), 1975- (Massachusetts Institute of Technology, 1998)
    • Atomic quantum memory for photon polarization 

      Bloom, Benjamin Jacob, S.B. Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2008)
      Using an ensemble of ultracold Cesium atoms in an optical cavity we demonstrate the efficient storage and retrieval of quantum information in the form of single photons. We use a photon that has scattered into the cavity ...
    • An attempt to measure the time delays of three gravitational lenses 

      Chistol, Gheorghe (Massachusetts Institute of Technology, 2007)
      I present the results of reduction and analysis of two seasons of gravitational lens monitoring using the Very Large Array (VLA) at 8.5 GHz. The campaign monitored five gravitational lenses, GL1608, GL1830, GL1632, GL1838, ...
    • Automatic detection of periodic sources in the K2 data sets 

      Molnar, Momchil Emil (Massachusetts Institute of Technology, 2016)
      We present an automated algorithm for the detection of periodic sources in the K2 data sets. Fast discreet Fourier transformations are used to compute the Fourier spectra of the targets and two different detection algorithms ...
    • Baffle material characterization for Advanced LIGO 

      Hunt, Cassandra R (Massachusetts Institute of Technology, 2008)
      The transition to Advanced LIGO introduces new sensitivity requirements for the LIGO interferometers. When light scatters away from the main laser beam, then scatters off the beam tube and returns to the main beam, noise ...
    • Bayesian modeling of microwave foregrounds 

      Rahlin, Alexandra Sasha (Massachusetts Institute of Technology, 2008)
      In the past decade, advances in precision cosmology have pushed our understanding of the evolving Universe to new limits. Since the discovery of the cosmic microwave background (CMB) radiation in 1965 by Penzias and Wilson, ...
    • The behavior of O - C curves for contact binaries in the Kepler catalog 

      Tran, Kathy, S.B. Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2013)
      In this thesis, we study the timing of eclipses for contact binary systems in the Kepler catalog. Observed eclipse times were determined from Kepler long-cadence light curves and "observed minus calculated" (0 - C) curves ...
    • A biomechanical study of a karate strike. 

      Wilk, Stephen Richard (Massachusetts Institute of Technology, 1977)
    • Bound states of pseudo-Dirac dark matter 

      Bhattacharya, Arindam(Arindam A.) (Massachusetts Institute of Technology, 2019)
      We study the bound-state spectrum in a simple model of pseudo-Dirac dark matter, and examine how the rate of bound-state formation through radiative capture compares to Sommerfeld-enhanced annihilation. We use this model ...
    • Boundary conditions, effective action, and Virasoro algebra for AdS₃ 

      Porfyriadis, Achilleas P (Massachusetts Institute of Technology, 2010)
      We construct an effective action of General Relativity for small excitations from asymptotic transformations and use it to study conformal symmetry in the boundary of AdS3. By requiring finiteness of the boundary effective ...
    • Building a better flat-field : an instrumental calibration projector for the Large Synoptic Survey Telescope 

      Vaz, Amali L (Massachusetts Institute of Technology, 2011)
      The Large Synoptic Survey Telescope (LSST) is a next-generation ground-based survey telescope whose science objectives demand photometric precision at the 1% level. Recent efforts towards 1% photometry have advocated in-situ ...
    • Building an apparatus for ultracold lithium-potassium Fermi-Fermi mixtures 

      Campbell, Sara L., S.B. Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2010)
      In this thesis, I designed and built laser systems to cool, trap and image lithium-6 and potassium-40 atoms. I also constructed the vacuum system for the experiment and experimentally tested a new method to coat the chamber ...
    • Ca2+ dependant synaptic modification 

      Huh, Dongsung, 1981- (Massachusetts Institute of Technology, 2004)
      It has been assumed that Ca2+ influx of different duration and amplitude would generate different level of potentiation. The conventional protocols of generating LTP have been 1. tetanic stimulation of presynaptic cell, ...
    • Calculation of the axial charge of a heavy nucleon in Lattice QCD 

      Pefkou, Dimitra Anastasia (Massachusetts Institute of Technology, 2016)
      In this thesis, we aim to calculate the non-renormalized axial charge gA of a heavy nucleon made out of quarks at the physical mass of the strange quark. We present the framework of Lattice QCD which makes the calculation ...
    • A catalog of new eclipsing binaries in the Kepler database 

      Kotson, Michael Christopher (Massachusetts Institute of Technology, 2012)
      In this thesis, we present a catalog of binary stars discovered in the publicly available Kepler database, none of which were included in previous such catalogs published by the Kepler science team. A brief review of other ...
    • Cavity and projectile dynamics in intermediate Froude number water entry 

      Kominiarczuk, Jakub K (Massachusetts Institute of Technology, 2007)
      Introduction: Water entry of projectiles has long been a topics of interest in both sciences and engineering. It began with Worthington, who in the late XIX century found experimentally that a cavity is being formed when ...
