Exploring Ransomware On The Oculus Quest 2, Michael Mahan

Master's Theses

Virtual Reality Head Mounted Displays, also coined VR headsets, have breached barriers that held back widespread adoption and usage in the past. While covering the reasons for this large-scale spread, the idea is introduced that HMDs, which are standalone units, can become targets for malware. This work explores how applicable Android ransomware is to the Oculus Quest 2’s attack surface, due to the Quest’s usage of Android 10 as a base operating system. Existing ransomware samples are evaluated to determine an abstract definition of ransomware. This work also introduces SRS, Simple Ransomware Sample, which acts as a Proof-of-Concept, a minimum …

Analysis Of Selection Bias In Online Adversarial Aware Machine Learning Systems, Victor Barboza Morais

Master's Theses

As is evident in areas of privacy, security, and ethics, the hindrances to research is the lack of validated real-world data. Therefore, people resort to creating their own dataset and/or artificially increasing the size of existing datasets. However, in areas like countermeasures of phishing, this is not only insufficient but could introduce bias in the dataset in the process.

To raise the awareness of bias in Machine Learning (ML) / Artificial Intelligence (AI) and its consequences, this work tries to gauge one of its occurrences reliably, namely selection bias when generating more samples from existing samples in a dataset. However, …

How The Notch Signaling Pathway And Mediator Work Together To Regulate Hasc Self-Renewal, Taylor Teach

Master's Theses

Obesity is a serious medical condition resulting from excess body fat that triggers changes in both quantity and quality of various cells that reside in adipose tissue, including adipose stem cells. Adipose derived stem cells are multipotent, self-renewing cells that have the ability to differentiate. This process can be controlled by environmental stimuli, transcription factors, and signal cascades that lead to gene transcription and protein expression specific to the cell’s fate. The Mediator complex and the Notch signaling pathway are two complexes that allow this to occur. There is still much unknown about the Mediator complex, the Notch signaling pathways, …

Effects Of Dietary Creatine Monohydrate Supplementation On Doxorubicin-Induced Hydrogen Peroxide-Mediated Global Cysteine Sulfenylation Of Rat Cardiac Tissue, Rachel Flowers

Master's Theses

Creatine monohydrate is prolifically used as an ergogenic aid but is less commonly used for its antioxidant properties. The use of creatine, as an antioxidant, has been studied in multiple disease domains as an intervention to improve skeletal muscle quality for Duchenne muscular dystrophy by impacting calcium ion sensitivity in myocytes, Huntington’s disease by facilitating regulation of succinate dehydrogenase in the citric acid cycle and amyotrophic lateral sclerosis by positively impacting muscular atrophy. Reactive oxygen species (ROS) impact both physiological and pathophysiological roles in aerobic life such that an imbalance to the redox environment of the cell can cause intracellular …

'As Vivid As Blood In A Sink': (Re)Reading Queerness And Repression In Teju Cole's Open City, Jack Hoda

Master's Theses

Teju Cole’s Open City (2011) is an exemplar work of contemporary fiction. For its complex representation of subjectivity, hypnotic narrative tone, and global political scope, the novel has been praised by readers and critics alike. Julius, the text’s first-person narrator, guides us along seemingly innocent wanderings throughout New York City, ruminating on history, art, and politics while presenting himself as the enlightened, cosmopolitan ideal. However, the shocking penultimate revelation that Julius raped a young woman from his past alters our encounter with the text and its narrator. We come to realize that this meandering novel is, in reality, a carefully …

A Research Framework And Initial Study Of Browser Security For The Visually Impaired, Elaine Lau, Zachary Peterson

Master's Theses

The growth of web-based malware and phishing attacks has catalyzed significant advances in the research and use of interstitial warning pages and modals by a browser prior to loading the content of a suspect site. These warnings commonly use visual cues to attract users' attention, including specialized iconography, color, and an absence of buttons to communicate the importance of the scenario. While the efficacy of visual techniques has improved safety for sighted users, these techniques are unsuitable for blind and visually impaired users. This is likely not due to a lack of interest or technical capability by browser manufactures, where …

Examining The Association Between Fictive Kin Care, Parental Attachment And Emotional Distress In College Students, Roxanne Watts

Master's Theses

Having a supportive and secure relationship with parents can predict less emotional distress in college students. In addition to parental support, many families leverage fictive kin caregivers to provide support. This is especially true in communities of racial and ethnic minorities. The present study investigated the association between fictive kin care, parental relationships, and emotional distress in college students. One hundred fourteen (N = 114) college students completed measures that assessed parental and fictive-kin relationships, social support, and emotional distress. A COVID-19 pandemic-related distress measure was also administered. Three hypotheses were tested. First, it was hypothesized that fictive kin …

In the United States, the tomato industry was worth $1 billion in 2020, and tomatoes are currently ranked second as the most consumed vegetable after potatoes. Tomato processors have striven to valorize pomace by-products, which contain seeds with valuable compounds such as 45% fiber, 30% oil, and 26% protein. The U.S. peach industry, which was worth $599 million in 2017, is also looking for alternative ways to utilize their seeds, made up of 52% oil. Both tomato and peach seeds are rich in bioactive compounds such as …

Emotions In Work And War: Comparisons Of Emotional-Cultures Of New Deal Ccc Enrollees And Wwii U.S. Army Enlistees, 1933-1945, Maeve Losen

Master's Theses

Though the Great Depression and Second World War were consecutive eras and overlapped in numerous aspects, scholarship often overlooks the commonalities between these periods. To demonstrate these eras’ shared qualities, this thesis examines the relationship in emotional-cultures—the cultural norms that dictated how individuals felt and demonstrated their emotions—among Civilian Conservation Corps (CCC) enrollees and U.S. Army enlistees during WWII.

The broad intent of this undertaking is to place the cultural history of the Great Depression and WWII in conversation and to show the advantage of inter- and multidisciplinary work by applying anthropological and historical theories of emotion. Though the historical …

Sensitivity Of A Lamp Assay For Detection Of The Dinoflagellate Amyloodinium Ocellatum In Simulated Field Conditions And Freeze Tolerance Of The Parasite, Robert Gonzales

Master's Theses

The obligate parasitic dinoflagellate Amyloodinium ocellatum causes amyloodiniosis in warm water marine fishes. The prolific parasite, which has a direct, three-stage life cycle, is highly infectious and can cause heavy losses in aquaculture. Prevention, biosecurity, and early detection are vital for control. In this work, microscopy and a loop-mediated isothermal amplification (LAMP) assay were compared for early diagnosis of A. ocellatum in cultured stocks, and the freeze tolerance of tomonts was assessed to determine if frozen wild fish used as fish food can serve as a potential vector for the parasite.

The lowest dinospore concentration that could be detected by …

Assessing The Effect Of Negative Mood States On Valence-Dependent Belief Updating, Aleksandr Karnick

Master's Theses

Individuals consistently tend to underestimate the likelihood of negative events happening to them and fail to update these beliefs adequately when provided with statistical evidence. However, depressed populations are better able to accurately update beliefs. It is not clear if the ability to update beliefs effectively is due to overall dysphoria or are partially due to momentary fluctuations of acute affective states. Undergraduates (N=83) completed a belief updating task where they estimated the likelihood of a negative event happening to them, were presented with the actual likelihood of the event, and then re-estimated the likelihood of the event happening to …

Master's Theses

This study sought to investigate fan reactions to the NCAA communication around the elimination of NC State from the 2021 Baseball College World Series. NC State was eliminated due to Covid-19 protocols. A content analysis was conducted by looking at posts from various NCAA related accounts on Instagram and Twitter: @ncaabaseball, @ncaa, @ncstatebaseball, @vandyboys, @hailstatebb, and @texasbaseball. Content was analyzed using frames such as Health/Covid-19, Fans, Team Spotlight, Game Update, Elimination, Hype, Merch, and Sympathy. The study concluded that the while NCAA accounts ignored the incident and Health/Covid-19 frames altogether, the posts about Health/Covid-19 from team accounts actually gained a …

Impact Of Primary Myoblasts On Macrophage Polarization In-Vitro, Olivia Welch

Master's Theses

Peripheral artery disease (PAD) is characterized by the development of atherosclerotic plaques on arterial walls, leading to the narrowing of blood vessels, resulting in ischemia in the downstream tissue. In the United States, 12% of the adult population is affected by PAD and its related symptoms. Current surgical revascularization techniques can be effective in part of the patient population, but there is a need for other options. Alternatively, collateral blood vessels, or natural bypass arteries, enlarge to increase blood flow to the ischemic tissue in a process called arteriogenesis, which has been studied as a therapeutic option. Cell-based therapies, such …

Assessing The Impact Of Bicycle Infrastructure And Modal Shift On Traffic Operations And Safety Using Microsimulation, Katherine E. Lee

Master's Theses

A transportation system designed to prioritize the mobility of automobiles cannot accommodate the growing number of road users. The Complete Streets policy plays a crucial part in transforming streets to accommodate multiple modes of transportation, especially active modes like biking and walking. Complete streets are referred to as streets designed for everyone and enable safety and mobility to all users. A strategy of complete streets transformation is to connect isolated complete street segments to form a complete network that improves active mobility and public transit ridership.

This research assessed the impact of efficiently and equitably connecting and expanding the biking …

Parametric Paraglider Modeling, Peter F. Heatwole

Master's Theses

Dynamic simulations are invaluable for studying system behavior, developing control models, and running statistical analyses. For example, paraglider flight simulations could be used to analyze how a wing behaves when it encounters wind shear, or to reconstruct the wind field that was present during a flight. Unfortunately, creating dynamics models for commercial paraglider wings is difficult: not only are detailed specifications unavailable, but even if they were, a detailed model would be laborious to create. To address that difficulty, this project develops a paraglider flight dynamics model that uses parametric components to model commercial paraglider wings given only limited technical …

Patterns Of Academic Help-Seeking In Undergraduate Computing Students, Augie Doebling

Master's Theses

Knowing when and how to seek academic help is crucial to the success of undergraduate computing students. While individual help-seeking resources have been studied, little is understood about the factors influencing students to use or avoid certain re- sources. Understanding students’ patterns of help-seeking can help identify factors contributing to utilization or avoidance of help resources by different groups, an important step toward improving the quality and accessibility of resources. We present a mixed-methods study investigating the help-seeking behavior of undergraduate computing students. We collected survey data (n = 138) about students’ frequency of using several resources followed by one-on-one …

System Performance Model And Control System For A Small-Scale Horizontal Axis Wind Turbine, Niko Banks

Master's Theses

Predicting the performance of wind turbines is a key part of the turbine design process and operation, as predictive models play a large role in determining potential power output and efficiency at different operating conditions to help maximize production. On small-scale wind turbines performance models become more complex, as the rotor aerodynamic performance depends not only on the tip speed ratio, but also on the flow Reynolds number. An accurate predictive model that includes this behavior on small-scale wind turbines can be used to find the optimal operating conditions for power output, and is also a critical component of the …

Fire Effects In Montane Meadows, Rosie Deak

Master's Theses

The impact of forest fires on downstream meadow communities across California is of great ecological interest, as meadows are an important source of biodiversity in this region. Over a century of fire suppression has led to increased forest stand densities, which in turn has resulted in less water availability due to increased transpiration of densely growing trees. This potentially has left less available water for downstream plant communities in meadows. If true, then high mortality wildfires in surrounding forest are predicted to lead to an increase in available downstream moisture where obligate and facultative-wetland taxa increase and dry-adapted upland taxa …

Impact Of Teaching Practices And Communication Climates On Participation In Computer Science Education, Jackie Krone

Master's Theses

One way to understand teaching is to view it as a people process rather than a presentation of knowledge. It follows that the role of an educator often extends beyond the primary subject matter and into the realm of classroom management. With this in mind, our research aimed to capture the various teaching practices, participation patterns, and communication climates that occur in virtual computer science classrooms. We sought to answer the following research questions related to virtual computer science classrooms at our institution: Who participates in virtual computer science classrooms, and is participation proportional to student demographics? Is there any …

The Impact Of Formal Education, Specialized Training, And Offense Type On Perceptions Of Employability: Can Bias Toward Hiring A Person With A Criminal History Be Mitigated?, Rheanna Standridge

Master's Theses

Gaining employment for returning citizens has been shown to reduce recidivism and contribute to a successful community reintegration. Yet, many employers remain skeptical when it comes to hiring formerly incarcerated job candidates for a variety of reasons. Though hesitations are often related to assumptions about a person’s dangerousness, there remain legitimate reasons, such as limited formal education and basic skills, that prevent returning citizens from finding work. Further, previous research suggests that hiring decisions are confounded by offense type, even if an employer would otherwise consider a person with a criminal history. Thus, it is unclear whether returning citizens’ level …

Virtual Teams During Covid-19: A Study On Group Perceptions, Emergent States, And Outcomes, Thomas Montagna

Master's Theses

Due to the COVID‐19 pandemic, university students were forced to transition to emergency remote learning that, for many, required an abrupt shift from traditional face-to face instruction. The current study leveraged the unique opportunity provided by the change in communication modalities to compare pre and post pandemic perceptions of teamwork. Using the input-mediator-output-input (IMOI) framework, this study sought to discover how group processes, emergent states, and outcomes differed for face-to-face and virtual group work. As part of a retrospective pretest design, a convenience sample of fifty-two graduate students from the University of New Haven completed a single survey that asked …

Characterization, Design, And Optimization Of Dual-Purpose Wind Turbines And Frost Protection Fans, Ethan Narad

Master's Theses

This thesis report outlines the creation of a MATLAB tool to design reversible machines that can function as both wind turbines and as agricultural frost protection fans. Frost protection fans are used to prevent crop loss during radiative freeze events during which a temperature inversion is present. Such a dual-purpose machine fundamentally has the constraint that it must use symmetric airfoils, so a suite of tools for automatically designing an optimized wind turbine blade with symmetric airfoils using the Blade Element Momentum (BEM) theory approach is presented. The BEM code is then re-derived and adapted for use with a frost …

Integration Of Electrical Impedance Spectroscopy For Multichannel Cell Culture Measurement, Conard Chan

Master's Theses

ELECTROCHEMICAL IMPEDANCE SPECTROSCOPY (EIS) has been widely used to study the electrical properties of biological material due to its non-invasive nature and experimental reliability. However, most of the precision impedance analyzers used in EIS only provide single- or two-channel measurements which are inadequate for larger-scale multiplexed measurements, such as those found in modern microfluidic cell culture experiments. The Biomedical Microsystems Laboratory has developed a 16-channel cell culture platform with integrated electrode arrays for monitoring cell growth and electrical properties (i.e., the so-called “electrical phenotype”). In this paper, a system consisting of a 16-channel solid-state analog multiplexer (MUX)paired with a low-cost, …

Autonomous Network Defence Using Multi-Agent Reinforcement Learning And Self-Play, Roberto G. Campbell

Master's Theses

Early threat detection is an increasing part of the cybersecurity landscape, given the growing scale and scope of cyberattacks in the recent years. Increasing exploitation of software vulnerabilities, especially in the manufacturing sector, demonstrates the ongoing need for autonomous network defence. In this work, we model the problem as a zero-sum Markov game between an attacker and defender reinforcement learning agents. Previous methods test their approach on a single topology or limit the agents to a subset of the network. However, real world networks are rarely fixed and often add or remove hosts based on demand, link failures, outages, or …
