The Effects of UV Irradiation on the Biosorption of Titanium Dioxide Nanoparticles to Heterotrophic Biomass

Creator:: Young, William M.
Abstract:: The production of titanium dioxide (TiO2) nanoparticles has increased significantly in the past decades, which has generated concern due to their known toxicity in the environment. As a result of the production, use and disposal of productions containing TiO2, TiO2 nanoparticles are often received by wastewater treatment facilities. The adsorption...

Modeling of Power Efficiency in a Magnetohydrodynamic Generator

Creator:: Redle, Michael T.
Abstract:: The introduction of an Magnetohydrodynamic (MHD) generator in coal or natural gas energy plants could significantly increase the efficiency by converting kinetic and thermal energy of the combustion exhaust to electrical energy by the generation of a Faraday and Hall current. The traditional MHD system was transformed into a simplified...

Utilization of Robot Ankle Torque to Account for Foot Placement Error

Creator:: Bernards, Mitchell F.
Abstract:: Modern walking robots have shown that dynamic gaits can be achieved without ankle motors. It seems logical that the additional control authority that they provide can be used to improve the stability of the walking gait against foot placement errors caused by low level control. This thesis develops and compares...

Adapting the Methylene Blue Sulfide Detection Method for Use in a Microfluidic in-situ Monitoring Device

Creator:: Monares, Shane W.
Abstract:: Sulfide is an important species to measure in environmental water samples. The spectrophotometric detection method for reduced sulfur species (sulfide) based on generation of methylene blue was adapted to work in an apparatus utilizing microfluidic PDMS mixing and observation cells with flow channels in the 100 μm range. The benefits...

Effects of Marijuana on Risky Decision-Making in Young Adult College Students

Creator:: Casey, Jorie L.
Abstract:: Marijuana (MJ) is a widely used illicit substance among adolescents and young adults. Frequent MJ use has been associated with impairments in cognitive flexibility and inhibition, both of which play important roles in decision-making. However, the impact of frequent MJ on decision-making performance is mixed and not well understood. The...

Protection of Nitrosomonas europaea from Silver Nanoparticle-Induced Inhibition through a Two-Step, Magnesium-Facilitated Mechanism

Creator:: Anderson, Joseph W.
Abstract:: The inhibitory effects of (Ag⁺) and silver nanoparticles (Ag NP) 3-5 nm in diameter (stabilized with polyvinylpyrrolidone (PVP)) and 20 nm (stabilized with citrate) on nitrification rates of the model ammonia-oxidizing bacteria (AOB) Nitrosomonas europaea were investigated. Experimental solutions contained HEPES buffer and ammonia (NH₃) in the presence and absence...

Detection and Segmentation of Bird Song in Noisy Environments

Creator:: Neal, Lawrence W.
Abstract:: Recent work in machine learning concerns the detection and identification of bird species from audio recordings of their vocalizations. Such analysis can yield valuable ecological information concerning the activity and distribution of species in the wild. Current species-identification methods require individual syllables of bird audio as input, but field-collected audio...

An Improved Chemical Kinetic Model Reduction in pyMARS for Liquid Propellants

Creator:: Moore, Cailin J.
Abstract:: The aerospace industry uses chemical kinetic models when designing propulsion systems to acquire specific details about the rate of chemical reactions, heat release, and combustion stability. These models, however, are too large and stiff to be useful as they can take weeks to run computations on. The pyMARS python package...

X-ray Emissions in Measurements of the Neutron Capture Cross Sections for the Production of ¹⁹⁷Hg and ¹⁹⁷Pt and Scoping the Science Parameter Space of Future X-ray Astrophysics Calorimeter Missions

Creator:: Keck, Mason L.
Abstract:: A spectral fitting routine was developed to analyze X-ray emissions in neutron capture decay processes that produce ¹⁹⁷Hg and ¹⁹⁷Pt. Through correcting for X-ray emissions, the 77.3 keV γ gamma ray intensities were analyzed. The thermal cross sections for the production of ¹⁹⁷Hg and ¹⁹⁷Pt were found to be 2088...

Mood-dynamic playlist : interpolating a path of emotions using a KNN algorithm

Creator:: Gaur, Shaurya
Abstract:: Users curate music playlists based on emotion to focus or relax, so streaming services often create playlists of songs to aid this process. Prior research focuses on generating playlists of a single mood or genre, although a few studies work to construct automatic playlists that transition between the genres of...
