Controlling Electromagnetic Surface Waves with Scalar and Tensor Impedance Surfaces.
(2013)
The propagation characteristics of electromagnetic waves on various isotropic (scalar) impedance surfaces have been studied for some time, in order to control surface waves and leaky-wave radiation. One and two dimensional ...
Development of a Time-Resolved Laser-Induced Fluorescence Technique for Nonperiodic Oscillations
(2016)
Time-resolved measurements of ion dynamics could be key to understanding the physics of instabilities, electron transport, and erosion in Hall thrusters. Traditional measurements of the ion velocity distribution in Hall ...
Demographic Stochasticity in Evolutionary Biology.
(2013)
Demographic stochasticity, the random fluctuations arising from the intrinsic discreteness of populations and the uncertainty of individual birth and death events, is an essential feature of population dynamics. Nevertheless ...
Numerical Study of Coronal Mass Ejections, Shocks, and Turbulence: from Chromosphere to 1 AU.
(2014)
My dissertation focuses on one of the major source of destructive space weather: coronal mass ejections (CMEs). By helping develop and utilizing a new data-driven global MHD model: The Alfven Wave Solar Model (AWSoM) in ...
Nanoparticles for Biomedical Applications: Photothermal Therapy and Nuclear Delivery.
(2013)
Cancer is still a grand challenge faced by society today. Nanomedicine addresses many of the serious issues associated with conventional treatments. Nanoparticles (NPs) are advantageous for therapy because they are minimally ...
Designing Thermal Modulators for Portable GC x GC Systems.
(2015)
Microelectromechanical systems (MEMS) have the advantage of scale and can be manufactured in bulk. One of the active areas of MEMS research is the development of micro-scale comprehensive two-dimensional gas chromatography ...
A NMR Investigation of Structure and Allostery in the Hsp70 Chaperone System.
(2010)
The Hsp70 Chaperone system is a complex molecular machine composed of proteins. It is responsible for assisting in protein folding/refolding/processing and transport. Hsp70 proteins have been historically associated with ...
HgCdTe Auger-Suppressed Infrared Detectors Under Non-Equilibrium Operation.
(2009)
A nearly universal goal for infrared photon detection systems is to increase their operating temperature without sacrificing performance. The limiting factor for cooling requirements is the dark current in the detector ...
Structural Characterization and Impedance Spectroscopy of Substituted, Fused-Ring Organic Semiconductors.
(2011)
Organic materials present a number of advantages over silicon that make them ideal candidates for modest performance devices like active matrix backplanes and RFID tags. The work detailed here describes both structural ...
Nonholonomic Virtual Constraints and Gait Optimization for Robust Robot Walking Control.
(2016)
Bipedal locomotion is well suited for mobile robotics because it promises to allow robots to traverse difficult terrain and work effectively in man-made environments. Despite this inherent advantage, however, no existing ...
