Noninvasive control of stochastic resonance and an analysis of multistable oscillators
(Georgia Institute of Technology, 2001-08)
A quantum Monte Carlo study of exchange and correlation in the silicon pseudo atom
(Georgia Institute of Technology, 2000-12)
Nuclear structure of the N=90 isotones
(Georgia Institute of Technology, 2001-12)
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 ...
Sensitive dependence of the motion of a legged robot on granular media
(Georgia Institute of Technology, 2009-03-03)
Legged locomotion on flowing ground (e.g., granular media) is unlike locomotion on hard ground because feet experience both solid- and fluid-like forces during surface penetration. Recent bioinspired legged robots display ...
Robotics in Scansorial Environments
(Georgia Institute of Technology, 2005)
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 ...
Toward a dynamic climbing robot
(Georgia Institute of Technology, 2006)
Simple mathematical models or ‘templates’ of locomotion have been effective tools in understanding how animals move and have inspired and guided the design of robots that emulate those behaviors. This paper describes a ...
