Evaluating Tropospheric Delay Modeling For Enhanced Geospatial Accuracy, Adeyinka Olaoluwa Olaseinde

Masters Theses

Interferometric Synthetic Aperture Radar (InSAR) is a vital technique for monitoring ground surface deformation across large spatial scales. However, variability in atmospheric water vapor, pressure, and temperature introduces tropospheric delays that can significantly affect measurement accuracy. These delays are often corrected using outputs from numerical weather prediction (NWP) models. RAiDER, an open-source Python package, facilitates this by estimating tropospheric delays using models such as the High-Resolution Rapid Refresh (HRRR). Previous studies have shown that weather model–based corrections can substantially reduce atmospheric noise in InSAR data but also highlight persistent residual errors, especially at spatial scales smaller than the model grid …

The Mediating Role Of Emotion Regulation Between Parent-Child-Relationship Quality And Psychological Health Of Adolescent Girls, Ethan Marcus Rick

White Racial Identity, Climae Change, And Social Attitudes, Alyssa Engle

Senior Honors Theses and Projects

This study examined how symbolic racism, political conservativism, and White racial identity predicts attitudes toward climate change among White Americans. Prior research suggests that racial resentment vaticinates social and political judgments beyond explicitly racial domains, including environmental issues and policies which disproportionately harm Black and marginalized communities. Building on this prior research, the present study investigated whether racial identity dimensions predict climate change distress, and whether symbolic racism mediates associations between conservative political orientation and climate concern. Seventythree White undergraduate students completed measures of racial identity, symbolic racism, distrust in climate science, political conservatism, and climate distress. As predicted, a …

Learned Helplessness: An Online Replication And Validation, Arshpreet (Sunny) Kandola

Graduate Theses/Dissertations

The current study entails the partial replication of a classic learned helplessness two-phase triadic design experiment within an online learning context and aimed to validate a new attributional style self-report measure designed to identify individual differences in tendencies to develop learned helplessness consistent with the original reformulation of the hypothesis. Further, recent innovations in neuroscientific technology have allowed for a deeper examination of the mechanisms at play, finding support for a major re-interpretation of the theory of learned helplessness - suggesting that helplessness is more so the default passive response, while the active ingredient that is detected or expected (i.e., …

Dystopian Politics In The Hunger Games Series, Tristan Hogan

Graduate Theses/Dissertations

Suzanne Collins’s The Hunger Games series takes readers to a fictional country known as Panem that hosts an annual nationwide celebration in which adolescents compete in a battle to the death. In this analysis, I approach this book series with a Marxist lens to argue that the capitalistic system in Panem satirizes American culture in the early 21st century. Every novel in the series, through this theory, can be read as what scholars identify as a “critical dystopia,” a defamiliarized version of our culture, upheld through institutions and social participation in a way that satirizes ours. I argue that the …

The Structure, Properties And Dissolution Behaviors Of Phosphate Glasses, Han Zhang

Doctoral Dissertations

The poor chemical durability remains a critical challenge for the application of phosphate glasses. This study investigates the compositional influences on the structure, properties and chemical durability of Li2O-ZnO-P₂O₅ glasses. Their structural characteristics were analyzed utilizing high-performance liquid chromatography, Raman spectroscopy, and X-ray photoelectron spectroscopy. The incorporation of (Li2O+ZnO) in LZeq glasses depolymerizes the phosphate network. In LZ40P and LZ45P glasses, Li⁺ initially replaces Zn²⁺ associated with non-bridging oxygens (NBOs) in Q² tetrahedra. Once the substitution in Q² is complete, further Li⁺ incorporation leads to the replacement of Zn²⁺ in Q^{1 …}

Computation Of Natural Relative Trajectories In The Elliptic Restricted Three-Body Problem, Dane Huck

Masters Theses

"Humankind’s presence in deep space is certain to increase throughout future decades. Future missions will continue to exploit the complex dynamics making use of liberation point orbits. Along with this trend is the rise of small satellites ("small sats") and fractionated spacecraft in general. Compared to traditional monolithic spacecraft, small sats can often have higher maneuverability, be a fraction of the cost, and be more expendable in nature. The growing interest in these two areas drives the need for improvements in the area of relative motion in deep space. One obvious use of small sats in deep space is for …

Bond Behavior Of Magnesium Potassium Phosphate Cement (Mkpc) Coating For Steel Reinforcement, Eric Williams

Masters Theses

"This research investigates the bond behavior of magnesium potassium phosphate cement (MKPC) coated mild steel deformed bars in conventional concrete and concrete repair materials. For typical steel reinforcement in concrete, a thin “passive layer” develops around the reinforcement, which protects the reinforcement from corrosion. The concrete carbonates over time, reducing the protection of the passive layer and allowing chlorides, which corrode the reinforcement, to penetrate at an increasing rate. In some cases, to combat this corrosion, a protective layer is added to the reinforcement prior to installation. Common protective layers include epoxy coatings or zinc galvanization. MKPC is a novel …

Effects Of Climate Change On Fungal Diversity And Function In Streams, Syeda Tasfia Imam

Masters Theses

"This study investigated the impact of climate change, particularly drought, on leaf decomposition and associated fungal and macroinvertebrate communities in freshwater ecosystems. With climate change, streams may experience altered hydrology, leading to shifts in community composition and biogeochemical processes. Fungi decompose organic matter, facilitate nutrient cycling, and support food webs. However, drought can disrupt these processes by reducing water availability, causing declines in fungal diversity and activity. I examined leaf breakdown and associated biota in 13 stream sites across varying hydrologic conditions, from perennial to ephemeral flow patterns. Flow duration varied during the 8-week study. Leaf breakdown was significantly related …

Auto-Tuning And Applications Of Transient Voltage Suppressor Models In Full-Wave Simulations, Daniel Peter Szanto

Masters Theses

System efficient electrostatic design (SEED) combines full-wave geometry information with SPICE models of non-linear protection devices, typically transient voltage suppression (TVS) diodes, to allow optimization and validation of electrostatic design (ESD) protection early in the design process. TVS models have previously been developed which may be used in SPICE simulation tools like Keysight ADS, but these models could not be used directly in full-wave simulation tools like CST Studio. A process was developed for converting existing ADS models of TVS devices to a form that can be used within a CST full wave/SPICE hybrid simulation. Three TVS models were converted …
