Characterization of Internal Formaldehyde Production within The Pandora Spectrometer Instrument
(Virginia Tech, 2021-01-19)Formaldehyde (HCHO), plays an important role in atmospheric chemistry and is an indicator of atmospheric oxidation capacity and surface ozone photo chemistry. The Pandora Spectrometer Instruments are deployed within the ... -
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) ... -
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 ... -
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 ... -
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 ... -
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 ... -
Protection of Falling Conductors into Flammable Vegetation Faults
(Virginia Tech, 2021-01-14)Increasing modernization of the world has brought about a human component to natural disasters, which are exacerbated by the growing threat of climate change. The Western United States and Australia have witnessed some of ... -
Thermoacoustic Analysis and Experimental Validation of Statistically-Based Flame Transfer Function Extracted from Computational Fluid Dynamics
(Virginia Tech, 2019-07-24)Thermoacoustic instabilities arise and sustain due to the coupling of unsteady heat release from the flame and the acoustic field. One potential driving mechanism for these instabilities arise when velocity fluctuations ... -
Ego Depletion-Induced Aberrant Driving in the Post-Work Commute
(Virginia Tech, 2020-12-11)Spillover research has shown that workday stress hampers commuting safety, while ego depletion research has demonstrated that prior self-regulation leads to performance decrements in subsequent tasks. This study sought to ... -
Implementation and Demonstration of a Time Domain Modeling Tool for Floating Oscillating Water Columns
(Virginia Tech, 2021-01-13)Renewable energy is a critical component in combating climate change. Ocean wave energy is a source of renewable energy that can be harvested using Wave Energy Converters (WECs). One such WEC is the floating Oscillating ... -
Securing the Public Cloud: Host-Obscure Computing with Secure Enclaves
(Virginia Tech, 2021-01-12)As the practice of renting remote computing resources from a cloud computing platform becomes increasingly popular, the security of such systems is a subject of continued scrutiny. This thesis explores the current state ... -
Factors Behind Construction Companies' Purchasing Decisions of Wood Products and Insight into how Local (In-State) Wood Product Suppliers can have a Bigger Market Impact
(Virginia Tech, 2021-01-12)Companies in the construction industry have a wide range of choices of suppliers for the company's needs in building materials. Local (in-state) suppliers within key southern states have issues gaining market share within ... -
