Wave Number Selection and Defect Dynamics in Patterns with Hexagonal Symmetry
(Georgia Institute of Technology, 2003-11-24)
Wave Number Selection and Defect Dynamics in Patterns with Hexagonal Symmetry Denis B. Semwogerere 108 Pages Directed by Dr. Michael F. Schatz We report quantitative measurements of wave number selection, ...
Chemical and structural modification of porous silicon for energy storage and conversion
(Georgia Institute of Technology, 2008-01-15)
This thesis describes the fabrication and modification of porous silicon and titania structures for the purposes of energy storage and conversion. The first chapter provides the reader with background information on porous ...
Nuclear structure of the N=90 isotones
(Georgia Institute of Technology, 2001-12)
Noninvasive control of stochastic resonance and an analysis of multistable oscillators
(Georgia Institute of Technology, 2001-08)
Integrating a Hierarchy of Simulation Tools for Legged Robot Locomotion
(Georgia Institute of Technology, 2008-09)
We are interested in the development of a variety of legged robot platforms intended for operation in unstructured outdoor terrain. In such settings, the traditions of rational engineering design, driven by analytically ...
Phase bubbles and spatiotemporal chaos in granular patterns
(Georgia Institute of Technology, 2001-12-04)
We use inelastic hard sphere molecular dynamics simulations and laboratory experiments to study patterns in vertically oscillated granular layers. The simulations and experiments reveal that phase bubbles spontaneously ...
Crucial role of sidewalls in velocity distributions in quasi-two-dimensional granular gases
(Georgia Institute of Technology, 2004-10-19)
Our experiments and three-dimensional molecular dynamics simulations of particles confined to a vertical monolayer by closely spaced frictional walls (sidewalls) yield velocity distributions with non-Gaussian tails and a ...
Lattice dynamics and melting of a nonequilibrium pattern
(Georgia Institute of Technology, 2003-03-14)
We present a new description of nonequilibrium square patterns as a harmonically coupled crystal lattice. In a vertically oscillating granular layer, different transverse normal modes of the granular square-lattice pattern ...
Computational nonlinear dynamics: monostable stochastic resonance and a bursting neuron model
(Georgia Institute of Technology, 2003-12-01)
Spin Valve Effect in Ferromagnet-Superconductor-Ferromagnet Single Electron Transistor
(Georgia Institute of Technology, 2005-03-30)
This thesis describes a research of suppression of superconducting gap in a superconducting island of a Ferromagnetic-Superconducting-Ferromagnetic Single-Electron-Transistor due to the fringing magnetic fields produced ...
