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 …

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 …

Fruits and vegetables are at the core of a healthy, balanced diet. They assist in preventing the development of chronic diseases such as hypertension, diabetes, cardiovascular disease, and cancer (Fadnes, et al., 2022). Aging is a natural biological process followed by disease, cognitive impairment, and a natural decline of the body’s ability to perform at its best. The older adult population is currently the fastest-growing population globally (El-Shebiney et al., 2022). Vitamin A is crucial for several parts of the body to function correctly. Despite the positive effects of Vitamin A on the body, the recommended dietary intake is not …

Circular Restricted Three Body Manifold Trajectories Via Koopman Operator Theory, Lindsey Langton

Master's Theses

There are a multitude of computational techniques capable of modeling the behavior of nonlinear dynamic systems over time. In the field of astrodynamics, the most frequently used tools are numerical integrators, specifically Runge-Kutta algorithms. These algorithms have successfully produced numerous two-body trajectories, as well as an increasing number of three-body trajectories when two-body dynamic models fail to produce Δv values within the realm of mission feasibility. Koopman operator theory is an alternative method for modeling nonlinear dynamic behavior that captures an approximation of a nonlinear dynamic system on a defined basis in the Hilbert space. The Koopman operator is an …

Investigating The Role Of Endothelin-1 In Reactive Astrocytosis, Candace Betancourt-Szymanowska

Master's Theses

Glaucoma is a progressive optic neuropathy which results in blindness for many patients, even with treatment. Endothelin-1 (ET-1) is a vasoactive peptide known to be aberrantly upregulated in the eyes of individuals with glaucoma. Optic nerve head astrocytes (ONHA) are the resident glial cell of the optic nerve head and are among the first cell types to undergo changes to a reactive phenotype. In this thesis, we investigated the role of ET-1 overexpression and its putative role in eliciting a reactive phenotype in ONHA by inducing lentiviral-mediated over-expression of EDN1. ONHA transduced with EDN1 (ONHA ET-1) were verified to be …

Transcleral Chemotherapeutic Delivery By Fibrin Sealant In The Treatment Of Retinoblastoma, Christopher Himes

Master's Theses

Retinoblastoma is the most common intraocular cancer in children, accounting for roughly 9,000 new cases each year—claiming the lives of up to 70% of cases in certain regions of the world. While modern retinoblastoma treatments in developed countries have significantly reduced mortality rates, post-treatment consequences such as vision loss, off-site organ dysfunction, and secondary metastases remain unmet clinical needs. Past studies have confirmed transscleral delivery as an efficacious means to achieve high intraocular drug concentrations possibly superior to the standard systemic regimen of vincristine, etoposide, and carboplatin (VEC) for tumor suppression. This led to several studies exploring the use of …

The Influence Of Maternal Size/Age Effects On The Physiological Responses Of Adult Female Gopher Rockfish (Sebastes Carnatus) To Ocean Acidification And Hypoxia, Dylan H. Sarish

Master's Theses

Climate change is rapidly reshaping the chemistry of the ocean. Fishes living in California coastal waters are experiencing increased ocean acidification and hypoxia (OAH) due to more frequent and intense upwelling. Nearshore rockfish may be particularly threatened by these conditions due to their long generational times. However, it is unknown how OAH may impact maternal physiology and reproduction in these viviparous fish. To understand the physiological effects of OAH during gestation, adult female gopher rockfish, Sebastes carnatus, were exposed to a variety of combined OAH stress treatments during different gestational stages. Routine metabolic rate (RMR), maximum metabolic rate (MMR), blood …

Stream Response To A Dam Removal: Mill Creek, Davenport, Ca, Jessica J. Williamson

Master's Theses

Dams have many effects on stream morphology and ecology, including a loss of sediment supply downstream, reduced access to the entire stream for aquatic fauna, and a flooded area upstream of the dam. Dams are a hurdle for migrating organisms such as anadromous fish, which is a group of concern. An over 100-year-old dam on Mill Creek, a stream draining a coastal watershed in central California, was removed in the fall of 2021. The site is in the Santa Cruz Mountains, where endangered salmonids such as steelhead, Oncorhynchus mykiss, have historically lived. To study the change in the stream from …

The Doctrine Of The Trinity In Southern African Seventh-Day Adventism: A Historical-Theological Study, 1887-1974, Grant Lottering

Master's Theses

The Topic

The doctrine of the Trinity in the history of the Seventh-day Adventist Church has often been viewed with suspicion, largely because many early Adventist pioneers expressed seemingly anti-Trinitarian sentiments. However, a review of Seventh-day Adventist publications reveals that early Adventists actually rejected Modalism, a misunderstood variation of Trinitarianism, rather than the biblical concept of the Trinity. When Seventh-day Adventist missionaries arrived in Africa in 1887, the earliest converts had a Dutch Reformed background and were already Trinitarian. Seventh-day Adventists found that their understanding of the Trinity aligned with these converts’ beliefs, and thus, they never needed to correct …

A Comparative Analysis Of Current Understandings Of The High Priestly Ministry Of Jesus In The Heavenly Sanctuary, Samuel Amirtharaj

Master's Theses

Problem

Seventh-day Adventists consider the subject of the sanctuary to be the kingpin that interconnects all of the other doctrines. Both Adventists and non-Adventists agree that it is the Adventist understanding of the sanctuary that sets them apart from other Christian denominations. Almost since the inception of the Church, there have been many critics of the Adventist doctrine of the sanctuary and its associated teachings, both from within and from without the Church. Former Adventists and non-Adventists alike have discredited the significance of the sanctuary. However, numerous books on the sanctuary have been published recently by Christian scholars; these books …

Fault Box Modeling Of Dip Slip Faults: A Framework For Fault Box Design And Future Studies, Hailey Pressnell

The behavior of soils during surface fault rupture is a serious concern in the planning and design of infrastructure that may be located within or near a fault zone. Challenges associated with developing mitigation measures for surface fault rupture include the uncertainty of fault rupture and the variability of fault behavior. Current analytical procedures define surface fault rupture according to the type of fault movement (strike slip, normal or reverse), the amount of displacement on the fault, and the mechanics of the material overlying the fault. The purpose of this thesis is to reconfirm analytical solutions and gain a better …

Separation And Surface Examination Of Spacecraft Cabin Particulates, Grace A. Belancik

Master's Theses

Particulate matter in the atmosphere is a known detriment to human health, but several factors affect any particulate’s particular toxicity including particle size, surface area, and chemical composition. Extensive studies have been conducted to examine particulate hazards on Earth, but in crewed spacecraft, like the International Space Station (ISS), the particulate environment is wholly unique due to both the controlled environment and lack of gravity. Atmospheric sampling studies are underway, but another convenient source of airborne particulates for analysis is the contents of the vacuum bags used by the astronauts to clean the air vents. However, no method currently exists …

Ml Model To Better Identify Instances Of Bullying Faced By Members Of The Lgbtq+ Community, Arslan Bisharat

Master's Theses

Cyberbullying poses a significant threat to online communities, with the LGBTQ+ community facing disproportionately higher rates of harassment. While existing cyberbullying detection systems have made progress in identifying general instances of online harassment, they often fail to capture the nuanced and context-dependent nature of LGBTQ+-targeted bullying. This thesis presents a novel approach to this challenge by developing SpectrumNet, an LGBTQ+-centric transformer-based model for cyberbullying detection. Our research was conducted in two phases. In Phase 1, we evaluated the effectiveness of pre-trained transformer models (RoBERTa, BERT, and GPT-2) in identifying LGBTQ+-related cyberbullying. Building on these findings, Phase 2 introduced SpectrumNet which …
