Influence of various wetting agents on water status in USGA greens as determined by their physical properties
(University of Missouri--Columbia, 2021)
Soil hydrophobicity is an increasing issue in sandy soils, affecting agricultural land and golf courses. This phenomenon causes water repellency and bypassing of hydrophobic root zones, limiting water accessibility. Due ...
Time-dependent response of reinforced concrete elements near collapse
(University of Missouri--Columbia, 2021)
loads on the time-dependent strength and stiffness characteristics of RC isolated slab column connections and RC beams. Concrete is experiences creep under compressive load, and plain concrete has experienced compressive failure at load levels of 80...
Accurate, fast, and robust 3D city-scale reconstruction using wide area motion imagery
(University of Missouri--Columbia, 2021)
Multi-view stereopsis (MVS) is a core problem in computer vision, which takes a set of scene views together with known camera poses, then produces a geometric representation of the underlying 3D model Using 3D reconstruction ...
Structural features of persistent homology and their algorithmic transformations
(University of Missouri--Columbia, 2021)
We re-examine the theory and orthodox methods that underlie the study of persistent homology, particularly in its calculation of homological cycle representatives that are associated to persistence diagrams. A common ...

Financial leverage and predictability of earnings
(University of Missouri--Columbia, 2021)
This study investigates whether firms' financial leverage affects earnings predictability. I posit and find that earnings predictability is negatively associated with firms' leverage. Further analyses using an instrumental ...
Multi-hazard resilience assessment of river-crossing bridges
(2021)
Bridge structures are required to possess high reliability and robustness against the concurrent effect of extreme loads and environmental attacks. To achieve such interrelated goals, it is necessary to assess the system ...
Quantifying greenhouse gas ebullition rates across varying land uses, sediment types, and water temperatures in wetland systems
(University of Missouri--Columbia, 2021)
Around the world, wetlands and other aquatic ecosystems release greenhouse gases (GHG) into the atmosphere. GHGs escape from these systems through the process of ebullition -- or bubbles being released from the aquatic sediments. Ebullition can...
Identifying circumstellar dust around oxygen-rich mira variables with maser emission via continuum elimination
(University of Missouri--Columbia, 2021)
Stars between about 0.8 and 8 times the mass of the Sun will eventually evolve, becoming asymptotic giant branch (AGB) stars, where they pulsate and eject mass from their atmospheres, forming dust shells in the space around them. Evolved low...

(University of Missouri--Columbia, 2021)
This dissertation consists of three chapters. In the first chapter, I analyze credible intervals for quantiles constructed using Bayesian bootstrap techniques and show that credible intervals constructed using the ...
Assessing fall velocity-maximum dimension relationships and particle size distributions for snowfall
(University of Missouri--Columbia, 2021)
Snowfall is an atmospheric phenomenon that can cause significant impacts to many aspects of daily life in Missouri. Further, no two snowfall events are exactly the same, as even small differences in environmental characteristics ...
