Mapping The Underthing: Literary Geography And Geographic Education In The Slow Regard Of Silent Things, Colby Mcclain

Master's Theses

This thesis examines the imagined geography of Patrick Rothfuss’ The Slow Regard of Silent Things. Through textual analysis, it investigates how fictional spaces can be mapped, the significance of toponyms (i.e., place-names), and the broader implications for literary and geographic studies. Of the fifty-two (52) toponyms analyzed, thirty-eight (38) were meaningfully identified using the text and the Oxford English Dictionary (OED), revealing deliberate naming schemes associated with function, emotion, or symbolism. These findings provide insight into the main character’s world, and her unique relationship with space and place. This study demonstrates that even wholly imagined settings have an underlying …

Doin' Time: Entertainment And Exploitation At Decommissioned Prison Museums In The United States, Jessi Robbins

Master's Theses

This thesis aims to explore how decommissioned prison museums in the US, such as Brushy Mountain State Penitentiary (BMSP), shape societal attitudes and understanding of the carceral system as a whole and the presence of systemic racism within by addressing three questions: (1) What histories do prison museums tell, and which are erased?, (2) How do objects displayed in prison museums reflect past and present racial attitudes toward the incarcerated?, and (3) Does visiting or working at a prison museum affect individual attitudes regarding the US carceral system? Grounded in James Scott’s (1992) concept of “hidden transcripts” and Michel Foucault’s …

Dewatering Of Chlorella Algae Using Co2 Gas Hydrate Formation For The Biofuel Production, Sumeet Oak

Master's Theses

When microalgae are processed for producing biofuel, dewatering the algae is an important step, particularly when combined with extracting valuable byproducts like algal oil. Conventional methods like centrifugation and filtration can be harsh on the algae and usually need high-energy inputs. In this work, the new application of CO2 gas hydrates as an algae dewatering agent was investigated. A CO₂ hydrate, CO2-nH2O, where n (n>5.75), is a nonstoichiometric compound where water molecules with hydrogen bonds are structured in an ice-like fashion to form polyhedral cavities. CO₂ gas hydrates are crystalline because gas molecules are trapped in a lattice of …

Assessing The Effect Of Prolonged Saltwater Exposure On Dna Recovery In Submerged Skeletal Remains From Sus Scrofa Domesticus (Erxleben, 1777), Malia Wellens

Master's Theses

Both water-related and mass disasters occurring over or in water (e.g., boating disasters, commercial plane crashes, and natural disasters) result in multiple deaths every year. Due to the ocean's vastness and lack of equipment, remains may not be recovered for some time, resulting in soft tissue decomposition, leaving bone as the last repository of recoverable DNA for identification purposes. Skeletal remains' physical and chemical components protect them from environmental deterioration and biological attack and preserve DNA well. Therefore, identifying an individual may depend on DNA obtained from skeletal remains. However, there is limited research on how long DNA can be …

Postmortem Detection Of Substance P And Met-Enkephalin Expression As A Possible Indicator For Pain Estimation Prior To Death, Amy M. Lischin

Master's Theses

Substance P (SP) and Met-Enkephalin (MET) are neuropeptides critical to the central nervous system (CNS) and are released as immediate responders to physical stressors like pain. In blood, SP and MET adapt based on an incident-death time interval to suggest the potential to use these as biomarkers in the assessment of pain prior to death. The mRNA and DNA manipulations of RNA isolation, cDNA synthesis, and RT-qPCR allowed for investigation into SP and MET gene expression (TACl, TACRl, OGFR) in those who experienced chronic tissue damage (e.g. domestic abuse) as compared to those who underwent an acute pain event (e.g. …

Evaluation Of Skeletal Dna From Bones Submerged In Stagnant, Tannin-Rich Blackwater, Jessica R. Behn

Master's Theses

Successful genetic identification of human remains is heavily dependent on environmental factors. This sentiment is stressed when considering those submerged in aqueous environments. However, the range of studies investigating the interaction of DNA degradation and skeletal remains is quite limited - especially those submerged in water. Consequently, this study aimed to quantify and determine the degradation rate of submerged skeletal element DNA in stagnant, tannin-rich blackwater wetland over a four-month period. To mimic human remains in a New England Pond environment, five macerated porcine femurs were submerged in an artificial pond aquarium and allowed to soak for three weeks, six …

Edouard Reményi And Johannes Brahms: A Lifelong Influence Reconsidered, Katherine Marie Martin

Master's Theses

Edouard Reményi was one of the first important influences in Johannes Brahms’s life and compositional career. Yet, beyond a single biography, much of what is commonly believed about Reményi is based on information provided by the Brahms literature.

By reexamining the accounts of Reményi in the Brahms literature, and comparing them with Mary Kelley and George Upton’s biography of Reményi and Robert Eshbach’s excellent research, the timeline of Reményi’s life and work can be clarified. Analysis of a set of three pieces for violin and piano demonstrates Reményi’s work as a composer and illustrates the style of Hungarian music that …

A Heuristic Approach To Portrait Segmentation And Its Application To Synthetic Bokeh Generation, Charles J. Snead

Master's Theses

Segmentation of portrait images is an important technique used to separate the foreground and background of an image. This separation of layers is useful for selectively applying post-processing techniques to enhance the quality of the image, such as blurring the background. Automatic portrait segmentation is a complex process that can be completed with a high degree of accuracy using deep learning with neural networks, but training and inference are often very computationally expensive. This thesis aims to take a heuristic approach to portrait segmentation by combining classical image processing and computer vision techniques into a solution that can be run …

Enhanced Post-Capture Automatic White Balance For Srgb Images, Eric Huang

Master's Theses

Automatic white balancing (AWB) aims to correct color casts caused by varying illumination conditions, typically assuming access to RAW sensor data. However, many real-world applications involve only sRGB images that have already been processed by in-camera pipelines. In these cases, traditional AWB algorithms often underperform due to the nonlinear transformations done by these pipelines.

This thesis builds upon a data-driven color correction framework introduced by Afifi et al. that relies on RGB-UV histograms and learned color transforms. A revised automatic white balancing (AWB) framework that improves both color accuracy and runtime efficiency is proposed. A fallback routine is implemented to …

Aiops–Driven Adaptive Anomaly Detection In Evolving Cloud Environments Using Transfer Learning, Mayur Shivakumar

Master's Theses

As cloud-based microservice architectures have become the foundation of contempo- rary enterprise solutions, performance interference, wherein co-located services com- pete for shared resources, remains a significant challenge. This phenomenon, often referred to as the noisy neighbor problem, manifests when one workload unexpect- edly increases the CPU, memory, disk I/O, or network consumption, resulting in latency spikes or throughput degradation for other services. While existing isolation mechanisms (e.g., cgroups and QoS policies) provide some mitigation, they rarely prevent contention entirely, particularly in dynamic, rapidly evolving environments with frequent code deployments.

This thesis proposes an AIOps-driven adaptive anomaly detection framework that integrates …

Using Camera Stations To Investigate Occupancy Probability And Habitat Associations Of Island Spotted Skunks (Spilogale Gracilis Amphiala) On Santa Rosa And Santa Cruz Islands, Desirae Thomaier

Master's Theses

The California Channel Islands are unique in that two islands (Santa Rosa and Santa Cruz) support two endemic mesocarnivores, the island fox (Urocyon littoralis) and the island spotted skunk (Spilogale gracilis amphiala). Following the near-extinction of island foxes in the early 2000s, island spotted skunk populations increased significantly. Now that foxes have recovered, skunk captures have precipitously declined - possibly due to interspecific competition with foxes who have a similar diet but a larger body size and wider temporal niche. It has been proposed that skunks selectively use canyon bottoms and drainages with high vegetation cover and that these areas …

Soil Discrimination By Particle-Correlated Raman Spectroscopy, Drew Kuroda

Master's Theses

Forensic soil analysis has had a rich history of providing valuable information for investigating criminal events. However, many modern forensic laboratories have stopped performing this analysis due to the perception that it is either too time-consuming or labor­ intensive. Further complicating the issue is the view that many forensic soil analytical methods are subjective due to their reliance on feature comparisons. Particle Correlated Raman Spectroscopy (PCRS) is a new method that was proposed to address both concerns by providing automated and objective analysis and comparison of sample mixtures. PCRS is an integrated technique that combines automated image analysis with Raman …

Detecting Software Anomalies In Microservices Using Spectrograms, Scalograms, And Convolutional Neural Networks, Snehith Jonnaikode

Master's Theses

The growing complexity of cloud-native microservices has intensified the need for robust anomaly detection mechanisms, particularly for misconfiguration-induced failures that often manifest subtly and propagate across service boundaries. This thesis proposes a comparative framework for runtime anomaly detection by transforming system metrics into frequency-domain representations—spectrograms using Short-Time Fourier Transform and scalograms using Continuous Wavelet Transform—and classifying them with Convolutional Neural Networks (CNNs). Evaluated on DeathStarBench, a production-grade microservices benchmark with injected anomalies in the Reservation and Recommendation services, the framework also includes baseline Long Short-Term Memory (LSTM) models trained on raw time-series features. Stratified 5-fold cross-validation shows that CNNs trained …

Peerproxy: A Webrtc Proxy For Http, Nathan Li-En Lee

Master's Theses

Advances in networking technologies have empowered individuals to easily self-host digital services such as websites and smart home systems. However, accessing these services externally often requires port forwarding, which requires manual router configuration, technical expertise in networking, and is sometimes restricted by internet service providers. Proxy-based services such as Ngrok and Cloudflare Tunnels simplify external access by using publicly hosted proxy servers, but introduce increased infrastructure costs and privacy concerns due to reliance on third-party servers that can inspect or store traffic.

This thesis presents PeerProxy, a novel framework that simplifies access to self-hosted web services without manual network configuration, …

Using Stable Isotope Analysis To Investigate The Trophic Ecology Of Aquatic Insects, Shelby Ann Medlock

Master's Theses

Despite their abundance on the landscape, ponds and associated macroinvertebrate assemblages have largely been underrepresented in scientific studies, which usually focus on lakes or streams. Similar to other waterbodies, ponds can harbor high levels of invertebrate biodiversity, which is important as aquatic insects are experiencing declines due to habitat destruction, pollution, climate change, and invasive species introductions. To evaluate how these threats impact pond insects and the ecosystem services they may provide, a thorough understanding of their ecology is essential. However, significant knowledge gaps remain, especially regarding trophic levels and species-specific diets. To address these knowledge gaps, I used carbon …
