GNSS-R Remote Sensing of the Ocean: Surface Waves and Related Phenomena
(2016)
In this thesis, we explore several fundamental issues in GNSS-R remote sensing. Global Navigation Satellite System - Reflectometry (GNSS-R) is a relatively young remote sensing technique proposed to measure geophysical ...
Separable Inverse Problems, Blind Deconvolution, and Stray Light Correction for Extreme Ultraviolet Solar Images.
(2013)
The determination of the inputs to a system given noisy output data is known as an inverse problem. When the system is a linear transformation involving unknown side parameters, the problem is called separable. A quintessential ...
Contribution of Crevasse Advection and Mixed Mode Calving to Glacier Dynamics
(2021)
Modeling of the climate system including, but not limited to, atmospheric dynamics, ocean dynamics, and ice dynamics, is one of the crucial scientific problems of the 21st century. This work focuses on modeling of iceberg ...
Europa's Plasma Interaction with Jupiter's Magnetosphere: Characterizing Variability of the Plasma Interaction with Multi-Fluid MHD Simulations
(2021)
Europa, one of Jupiter’s Galilean moons, is embedded in the region of space dominated by Jupiter’s magnetic field known as Jupiter’s magnetosphere. The interaction of Jupiter’s magnetospheric plasma and magnetic field with ...
Supersonic, Single-Mode and Dual-Mode Kelvin-Helmholtz Instability Experiments Driven by a Laser-Produced Shockwave
(2017)
We developed a novel experimental platform that utilizes a laser-produced shockwave to study the evolution of hydrodynamic instabilities in a steady, supersonic (compressible) flow, from precision-machined and well-characterized ...
A Data-Driven Understanding of Plasma Transport in Saturn's Magnetic Environment
(2020)
In 2004 the Cassini-Huygens mission arrived at Saturn. As the first ever Saturn
orbiter, Cassini collected data reaching from the largest moon, Titan, at 20 Saturn
radii (Rs), to the atmosphere during its death plunge in ...
Blast-Wave-Driven, Multidimensional Rayleigh-Taylor Instability Experiments.
(2009)
This thesis discusses experiments well-scaled to the blast-wave-driven instabilities that are believed to occur during the explosion phase of SN1987A. Blast waves occur following a sudden, nite release of energy, and consist ...
Anisotropic Diffusion of Neutral Particles in Stochastic Media.
(2009)
This work introduces a new homogenization theory for the transport of particles in stochastic media. This theory utilizes a nonclassical form of the Boltzmann equation in which the locations of the scattering centers in ...
Global Hall Magnetohydrodynamics and Coupled Fluid-Kinetic Simulations of Mercury's Dayside Magnetopause Dynamics
(2023)
Mercury possesses a miniature yet dynamic magnetosphere driven primarily by the solar wind through magnetic reconnection. Because Mercury is 60% closer to the Sun than Earth, its magnetosphere routinely experiences stronger ...
Improving Barotropic Tide Modeling in MPAS-Ocean and Estimating Changes in Future Tides
(2023)
Modeling the ocean is critical for understanding both present and future risks posed by climate change on coastal communities. Ocean tides in these regions will continue to change over the following decades, yet tides are ...
