Lee M. Waid: An Oral Historical Case Study of Students from an All-Black Rural Virginian School between 1963 and 1970
(Virginia Tech, 2021-01-19)This qualitative study reflects the researcher's aim to capture the oral histories of students who attended Lee M. Waid, an all-Black rural Virginian school, between 1963 and 1970. This purpose lies in the researcher's ... -
Balancing the Water Budget: the effect of plant functional type on infiltration to harvest ratios in stormwater bioretention cells
(Virginia Tech, 2021-01-19)Stormwater bioretention cells (BRCs) are a variety of green stormwater infrastructure with the potential to restore pre-urban water balance, provided they can be tailored to infiltrate and evapotranspire (i.e., harvest) ... -
Particle Sensing in Gas Turbine Inlets Using Optical Measurements and Machine Learning
(Virginia Tech, 2021-01-19)Propulsion systems are exposed to a variety of foreign objects that can significantly damage or impact their performance. These threats can range from severe dangers such as sandstorms and volcanic eruptions, which can ... -
Efficient H2-Based Parametric Model Reduction via Greedy Search
(Virginia Tech, 2021-01-19)Dynamical systems are mathematical models of physical phenomena widely used throughout the world today. When a dynamical system is too large to effectively use, we turn to model reduction to obtain a smaller dynamical ... -
A Synthesis of Geometry and Light
(Virginia Tech, 2021-01-19)The poetics of an architecture of a moment is explored through design of a contemplative room (wherin the geometric transformation of a cubic base to a cone) demonstrates the rhythmn and proportion of the construction of ... -
Technoeconomic Analysis of Textured Surfaces for Improved Condenser Performance in Thermoelectric Power Plants
(Virginia Tech, 2021-01-19)Nonwetting surfaces including superhydrophobic (SHS) and liquid infused surfaces (SLIPS) exhibit diverse exceptional characteristics promoting numerous application opportunities. Engineered textured surfaces demonstrate ... -
The Role of Actively Created Doppler shifts in Bats Behavioral Experiments and Biomimetic Reproductions
(Virginia Tech, 2021-01-19)Many animal species are known for their unparalleled abilities to encode sensory information that supports fast, reliable action in complex environments, but the mechanisms remain often unclear. Through fast ear motions, ... -
Inclusive and exclusive electron scattering data analysis from Jefferson Lab experiment E12-14-012
(Virginia Tech, 2021-01-19)Since the first observations of neutrino oscillation, neutrino experiments have come a long way toward precise measurements of the neutrino oscillation parameters, but some obstacles still remain. The next generation of ... -
Imagining a NeoFreudian Mind Interface: A Normative Model of Medical Humanities Research
(Virginia Tech, 2019-07-29)This thesis argues for a new theory of medical humanities practice and research, known as Mind Interface Theory. It begins with the claim that Sigmund Freud expanded medical metaphysics considerably in "A General Introduction ... -
Explicitly correlated Green's function methods for calculating electron binding energies
(Virginia Tech, 2019-07-29)Single-particle Green's function method is a direct way of calculating electron binding energy, which relies on expanding the Fock subspace in a finite single-particle basis. However, these methods suffer from slow asymptotic ... -
Evaluating the Fracture Potential of Steel Moment Connections with Defects and Repairs
(Virginia Tech, 2020)Steel moment frames are a popular seismic-force resisting system, but it is believed that they are susceptible to early fracture if there is a stress concentration in the plastic hinge region, also known as the protected ... -
Thin-Film Polymer Nanocomposites Composed of Two-Dimensional Plasmonic Nanoparticles and Graphene
(Virginia Tech, 2019-07-26)Plasmonic polymer nanocomposites contain plasmonic nanoparticles that are dispersed within a polymer. The polymer matrix strongly influences the optical properties of plasmonic nanoparticles. It is imperative to understand ... -
Architecture as Living Memory: Building Across Borders
(Virginia Tech, 2021-01-15)Border delineations and walls have been used to protect cities and towns throughout history. In the present age of modern surveillance and advanced military technology however, physical walls have much less significance ... -
Exploring Sibling Relationships in Latino/a/x Immigrant Families
(Virginia Tech, 2021-01-15)Siblings are the longest lasting relationships most individuals may experience in their life. What makes sibling relationships unique is the overlap of both shared and unshared experiences. While there is limited research ... -
Refugee migration stress and family function: A phenomenological study of refugee mothers from East and Central Africa
(Virginia Tech, 2019-07-25)Refugee families who flee their homes as a result of conflict or persecution and face stressful migration experiences often struggle with trauma that may put them at increased risk for family discord and dysfunction. The ... -
Design and Implementation of a Multiphase Buck Converter for Front End 48V-12V Intermediate Bus Converters
(Virginia Tech, 2019-07-25)The trend in isolated DC/DC bus converters is to increase the output power in the same brick form factors that have been used in the past. Traditional intermediate bus converters (IBCs) use silicon power metal oxide ... -
Convergence of Kernel Methods for Modeling and Estimation of Dynamical Systems
(Virginia Tech, 2021-01-14)As data-driven modeling becomes more prevalent for representing the uncertain dynamical systems, concerns also arise regarding the reliability of these methods. Recent developments in approximation theory provide a new ...
