An Ising-like model to predict dielectric properties of the relaxor ferroelectric solid solution BaTiO3 - Bi(Zn1/2Ti1/2)O3, An Ising-like model to predict dielectric properties of the relaxor ferroelectric solid solution BaTiO₃ − Bi(Zn₁/₂Ti₁/₂)O₃

Creator:

Jackson, Dennis L.

Abstract:

We developed a model to investigate the dielectric properties of the BaTiO₃ − Bi(Zn₁/₂Ti₁/₂)O₃ (BT-BZT) solid solution, which is a relaxor ferroelectric and exhibits long range disorder. The model uses ab initio methods to determine all polarization states for every atomic configuration of 2 x 2 x 2 supercells of...

Preliminary framework for the run-ahead predictive simulation software (RAPSS)

Creator:

Makinson, Kevin A.

Abstract:

The Run-Ahead Predictive Simulation Software (RAPSS) is an architecture designed for faster-than-real-time decision support for operators of complex networks. To enable further development of the RAPSS methodology, the necessary proof of principle is illustrated in two applications: decision support for shift technical advisors in nuclear power plant control rooms (RAPSS-STA),...

Use of BC-523a liquid scintillator for simultaneous neutron spectroscopy and gamma counting with the implementation of a neutron history reconstruction algorithm

Creator:

Frey, Wesley D.

Abstract:

Real-time, high efficiency neutron spectroscopy has, historically, been a persistent challenge in the field of radiation detection and, for the most part, has gone unsolved. The most promising method to resolve this challenge, is the boron-capture technique using an organic scintillation system (BC-523a). Detectors that utilize this method possess an...

Virtual Element Methods for Magnetohydrodynamics on General Polygonal and Polyhedral Meshes

Creator:

Naranjo, Sebastián

Abstract:

The aim of this dissertation is to construct a virtual element method (VEM) for models in magneto-hydrodynamics (MHD), an area that studies the behavior and properties of electrically conducting ﬂuids such as a plasma. MHD models are a coupling of the Maxwell’s equations for electromagnetics and models for ﬂuid ﬂow....

Amorphous TiO₂ : A Thin Film Synthesis Route to Stabilization of Metastable TiO₂ Brookite

Creator:

Haggerty, James E. S.

Abstract:

Structure-specific synthesis processes are of key importance to the growth of polymorphic functional compounds such as TiO₂, where material properties strongly depend on structure as well as chemistry. The robust growth of the brookite polymorph of TiO₂, a promising photocatalyst, has been difficult in both powder and thin-film forms due...

Nonlinear terahertz spectroscopy of carbon nanomaterials and semiconductor nanostructures

Creator:

Paul, Michael Jason

Abstract:

This thesis will cover my work relating to the developing field of terahertz (THz) science and technology. It will present experimental and theoretical studies investigating the optical and electrical properties of various material systems using novel THz imaging and spectroscopy techniques. Due to its low photon energy, THz imaging and...

Creating Community: A Case Study of Students’ Experiences in Inquiry-Based Learning

Creator:

Schaub, Branwen

Abstract:

We now have broad consensus in the mathematics education research community that active, inquiry-based classrooms provide a wealth of learning benefits for students (Freeman et al., 2014; Laursen et al., 2014; Theobald et al., 2020). Classrooms that utilize inquiry throughout the entire structure of the course, as opposed to the...

Community Colleges Creating Academic Programming for Rural Areas

Creator:

Garcia-Chitwood, Jean

Abstract:

Community colleges serve various populations as part of their missions. Many community colleges serve the people who live in rural communities and are challenged with fewer financial resources. The term rural is not easily defined, and many variables need to be considered when creating academic programming for rural populations. There...

A thin codimension-one decomposition of the Hilbert Cube

Creator:

Phon-On, Aniruth

Abstract:

For cell-like upper semicontinuous(usc) decompositions G of finite dimensional manifolds M, the decomposition space M/G turns out to be an ANR provided M/G is finite dimensional ([Dav07], page 129 ). Furthermore, if M/G is finite dimensional and has the Disjoint Disks Property (DDP), then M/G is homeomorphic to M ([Dav07],...

Exploring Student and Expert Understanding of Thermodynamic Potentials, Legendre Transformations, and Independent Variables in Thermodynamics

Creator:

Vignal, Michael

Abstract:

Thermodynamic potentials are energies that can describe a thermodynamic system in terms of different mathematically independent variables. Some of these potentials describe particular thermodynamic systems or processes in particularly convenient ways. In this dissertation, I discuss the different ways that students and experts reason about quantities in thermodynamics within the...
