Beyond Scattering: Identifying the Boundaries of Light Control with a Genetic Wavefront Optimization Algorithm

Creator:: Weller, Jesse A.
Abstract:: The ability to focus light through strongly scattering materials is opening up exciting new avenues in many fields, such as optics, computer vision, biology, and medicine, which utilize light delivery and imaging techniques. Efficient, high resolution wavefront shaping and optimization methods are crucial to enabling this new capability. In this...

Optical, electronic, and thermodynamic properties of layered mixed anion compounds

Creator:: Vielma, Jason Michael
Abstract:: Mixed anion compounds that form ZrCuSiAs-type crystal structures exhibit remarkable properties such as superconductivity at low temperatures, hole conduction with optical transparency in the visible region, and exciton absorption at room temperature. In this thesis, properties of a selected group of materials out of the very large set of mixed...

First principles study of finite temperature phase stability in (Cu,Ag,Au)In₂ and Al₂Cu alloys

Creator:: Holmes, Aleczander S.
Abstract:: The common choice in computational approximations, from 0 K to room temperature, of solid materials is to assume the structure remains unchanged at low temperatures. Often such an approximation is a very reasonable assumption. However, this approximation is not absolute and can break down even for relatively simple materials such...

First principles studies of optical, electronic and mechanical properties of organic molecules and solids

Creator:: Barras, Faye Lyn
Abstract:: This thesis presents the results of quantum-mechanical first principles calculations of optical, electronic and mechanical properties of organic molecules and solids, which have diverse potential applications such as photovoltaics, flexible electronics, and mechanical catalysts with applications in force sensors and self-healing materials. The electronic and optoelectronic properties of organic thin...

Computational study of the structure of indium alloys at low temperatures using ab initio methods

Creator:: Shin, Hongsik (Jay)
Abstract:: Crystals are solid materials with periodic and symmetric molecular patterns. The structure of a crystalline solid determines its properties, making it essential to study its structures. From the principle of minimum energy, a crystal will choose a structure with the lowest free energy F = U – TS. At low...

Monte Carlo Simulations of Structure and Melting Transition of Small Ag Clusters

Creator:: Collins, Lee
Abstract:: The behavior of small atomics cluster largely depends on their geometry, due to the high ratio of surface atoms to interior atoms. One interesting aspect to study clusters centers around characterizing the transition behavior between nite and bulk materials, where the ratio of surface atoms to interior atoms is very...

Generalization of the Ostrowski-Schneider main inertia theorem

Creator:: Hill, Richard David
Abstract:: As indicated by the title, this thesis generalizes the Main Inertia Theorem of Ostrowski and Schneider [8]. The first three results concern the formation of a polynomial function f(A, A*, H) so that the existence of an hermitian H for which f(A, A*, H) is positive definite is a necessary...

Monte Carlo studies of classical Heisenberg spins on face-centered-cubic lattices : effects of strain, interlayer coupling, and dilution of lattice

Creator:: Park, Seongweon
Abstract:: This thesis presents the results from Monte Carlo calculations on classical vector spins in face-centered-cubic (FCC) lattices. The goal of the study was to understand the effect of interlayer coupling, dilution of magnetic atoms in the lattice, and symmetry-changing strain. Experimental work by T. M. Giebultowicz et al. and J....

Vegetation and Small Mammal Responses to Western Juniper (Juniperus occidentalis) Control in Eastern Oregon

Creator:: Morozumi, Corinne N.
Abstract:: Shrub-steppe ecosystems of western North America provide habitat for many wildlife species, are important components of public and private rangelands, and offer recreational opportunities for millions of people. They are some of the most vulnerable ecosystems in the United States and have been altered by human activities such as livestock...

G, a language based on demand-driven stream evaluations

Creator:: Placer, John R.
Abstract:: A programming paradigm can be defined as a model or an approach employed in solving a problem. The results of the research described in this document demonstrate that it is possible to unite several different programming paradigms into a single linguistic framework. The imperative, procedural, applicative, lambda-free, relational, logic and...
