Theoretical modeling of pilot-wave hydrodynamics
In this thesis, we develop and apply a number of theoretical models describing the dynamics of a droplet walking on a vibrating liquid bath. We first review the hierarchy of theoretical models developed to describe this system. We begin with the stroboscopic model of Oza et al. (2013), and …

Theoretical Modeling Of Electron Transport In Molecular Devices
… the sizes of these dots. In this thesis, we used theoretical tools such as the equation of motion Green's function technique, non-equilibrium Green's functions and linear response theory to try to understand the physics underlying the electron transport processes in some of the systems mentioned …

Theoretical Modeling of Polymeric and Biological Nanostructured Materials
… that scattering methods require non-trivial data modeling, particularly in the case of periodic structures, which result in strong correlations between scattered beams. The dynamical theory (DT) model offers an exact model for interpreting off-specular signals from periodically structured surfaces …

Theoretical modeling of micellization and solubilization in ionic surfactant systems
Ionic surfactants constitute a very important class of surfactants, both from an academic as well as from a commercial viewpoint. In most commercial applications involving ionic surfactants, the selection of the surfactant is based on its aqueous bulk solution properties, including its …

Experimental and theoretical modeling of DNAPL transport in vertical fractured media
In recent years, groundwater contamination by dense, non-aqueous phase liquids (DNAPLs) such as chlorinated solvents and polychlorinated biphenyls (PCBs) has become an important environmental concern in many industrialized areas. Accidental spills, poor storage facilities and inadequate disposal …

Theoretical Modeling of Radiation-driven Atomic Kinetics of a Neon Photoionized Plasma
We report on a theoretical study on atomic kinetics modeling of a photoionized neon plasma at conditions relevant to laboratory experiments performed at the Z-machine in Sandia National Laboratories. We describe an atomic kinetics model and code, ATOKIN, that was developed and used to compute the …

Time-domain diffuse correlation spectroscopy: instrument prototype, preliminary measurements, and theoretical modeling
… of multi-layer media. We further discuss the theoretical considerations of modeling the light interaction with tissue, necessary for reliable estimates.

Computational and Theoretical Modeling of Two Dimensional Infrared Spectra of Peptides and Proteins
… infrared (2D-IR) spectroscopy evolved out of the theoretical underpinnings of nonlinear methods to provide a means of investigating detailed molecular structure on ultrafast timescales. This opens up new possibilities for the study of protein folding and molecule-solvent interactions through …

Carbon nanotubes and graphene in aqueous surfactant solutions : molecular simulations and theoretical modeling
… describes combined molecular simulations and theoretical modeling studies, supported by experimental observations, on properties and applications of carbon nanotubes (CNTs) and graphene sheets dispersed in aqueous surfactant solutions. In particular, the role of the bile salt anionic …

Theoretical modeling of the actuation mechanism in integrated induced strain actuator/substructure systems
Induced strain actuators have been integrated with conventional structural materials to serve as energy input devices or actuating elements in many engineering applications implementing intelligent material systems and structures concepts. In order to use the actuation mechanism produced by the …

On mitigation of hydrogen embrittlement and theoretical modeling of hydrogen accelerated fatigue crack growth
… fatigue crack growth, we first attempt to theoretically model fatigue crack propagation induced by alternating crack tip plastic blunting and re-sharpening in the mid-range of growth rates. The model is so designed that it relies on inputs from experiments that measure macroscopic material …

Theoretical Modeling with Validation of a Combined HQ-Liner System for Turbofan Engine Noise Control
… sector of the inlet of a turbofan engine. A theoretical model is developed to predict the performance of this system assuming that the engine inlet is a circular lined duct with uniform mean flow. The tube-duct interfaces are modeled as finite piston sources that couple the sound field inside …

Computational modeling of organic structure, spectra, and reactivity
Theoretical modeling of organic molecules and reactions is a powerful tool and can lead to further insight into these chemical systems. Modeling allows portions of the potential energy surface that cannot be examined experimentally, such as transition states. These transition states can lend …
