    • A Study on Porous Silicon Gas Sensors: Metal Oxide Depositions to Organic Materials 

      Lin, Arthur (Georgia Institute of Technology, 2015-08-18)
      This paper has two main topics. The first topics covers the detection of volatile organic compounds with porous silicon (PSi) sensors. The second part explores the possibility of using conducting polymers as coatings for ...
    • Dependence of escape fraction of ultraviolet radiation on galaxy mass 

      Demchenko, Vasiliy Grigoriyvich (Georgia Institute of Technology, 2013-05-08)
      Using the N-body, adaptive mesh-refinement, ray-tracing code Enzo, we studied the escape fraction of ultraviolet radiation in the early universe. We obtained data from a simulated cube 1 Mpc across of the early universe ...
    • Design of an actively cooled grid system to improve efficiency in inertial electrostatic confinement fusion reactors 

      Seltzman, Andrew (Georgia Institute of Technology, 2008-05-05)
      Traditional inertial electrostatic confinement (IEC) fusion reactor designs utilize an ion accelerating grid fabricated out of a refractory metal capable of operating at high temperatures to radiate off heat imparted by ...
    • Determining the minimal covering set of parameter spaces for phenomenological gravitational waveforms 

      Burns,  Dustin (Georgia Institute of Technology, 2011-05-09)
      Gravitational wave observatories are now trying to detect gravitational waves, ripples in space time predicted by Einstein’s theory of General Relativity, from sources such as merging binary star and black hole systems. ...
    • Development of Porous Silicon Microfilters 

      Campbell, Jenna (Georgia Institute of Technology, 2009-05-04)
      This study develops a one-step anodization separation process (OSS) after examining two step and multi step liftoff procedures in which porous silicon (PS) films lift off from their substrates. This lift-off process provides ...
    • The effects of fecl3 intercalation on the optical properties of multilayer epitaxial graphene 

      Johnson, Christine (Georgia Institute of Technology, 2012-05-07)
      In this study we investigate the effects of intercalation of graphene with Iron III Chloride on the optical and electronic properties of the multilayer graphene. While both the optical properties and the electronic properties ...
    • An FPGA-based microarchitecture for the implementation of quantum gates with trapped ions 

      Nichols, Charles Spencer (Georgia Institute of Technology, 2012-12-18)
      Quantum computing promises to revolutionize computing by providing exponential speed improvements to classically difficult problems. Over the past 30 years, experimental research has progressed from manipulating quantum ...
    • Graphene nanoribbon array fabrication by oxygen gas plasma etching through sub-micrometer porous filters 

      Shaw, David (Georgia Institute of Technology, 2009-08-07)
      We investigate a novel method of fabricating a network of graphene nanoribbon structures. The process is a sharp departure from conventional nanolithographic techniques in both method and amount of time required. Epitaxial ...
    • Nematic Order in Spherical Geometries 

      Devaiah, Sharan (Georgia Institute of Technology, 2010-05-11)
      Nematic Liquid crystals (NLC) are rod like molecules that in the absence of external influences arrange themselves parallel to each other and hence tend to point in a given direction. The average orientation of these ...
    • Nontrivial Impact 

      Karsai, Andras (Georgia Institute of Technology, 2015-08-18)
      The purpose of this investigation is to identify and calculate the forces that occur on an impulsive object as it intrudes into granular media. The system analyzed is a computational model of a sinusoidally actuated ...
    • Particle Image Velocimetry of Collapsing Toroidal Droplets 

      Berger, Eric M. (Georgia Institute of Technology, 2015-08-18)
      The goal of this study is to explore the mechanism by which unstable toroidal droplets collapse inwardly. As such, particle image velocimetry methods will be employed in obtaining an experimental picture of the velocity ...
    • Reduced Model for Gravitational Wave Sources 

      Maganazertuche, Lorena (Georgia Institute of Technology, 2015-08-18)
      One of the most interesting and exotic systems in the universe is a system of two black holes. When black holes orbit each other, they will eventually collide, forming a single black hole with a mass less than the sum of ...
    • Scaler System Testing in the HAWC Experiment 

      Browning, Tyler (Georgia Institute of Technology, 2010-05-12)
      TeV gamma rays probe the non-thermal Universe in ways that are not possible at other wavelengths. The HAWC observatory, under construction in Mexico, will be able to analyze and survey the TeV sky more completely than any ...
    • Star-Disk Collisions in the Galactic Center 

      Kieffer, Thomas F. (Georgia Institute of Technology, 2015-08-18)
      Recent observations of the Galactic Center (GC) have revealed that there is a relative paucity of Red Giant (RG) stars within the central parsec. However, these observations conflict with our current theoretical ...
    • State Space Partitions of Stochastic Chaotic Maps 

      Heninger, Jeffrey M. (Georgia Institute of Technology, 2014-05-05)
      The finest resolution that can be achieved in any real chaotic system is limited by the presence of noise. This noise can be used to define neighborhoods of the deterministic periodic orbits using the local eigenfunctions ...
    • Ultra-Close Tidal Disruption Events with Prompt Hyperaccretion 

      Evans, Christopher (Georgia Institute of Technology, 2015-08-18)
      A bright flare from a galactic nucleus followed at late times by a t^-5/3 decay in luminosity is often considered to be the signature of a tidal disruption of a star by a massive black hole. The flare and afterglow are ...
