Computational Representation, Analysis And Verification Of Requirements In Engineering Design And Systems Engineering, Chandan Kumar Sahu

All Dissertations

Systems are developed to satisfy a set of requirements derived from stakeholders’ needs, defining the problem space for which the system is created as a feasible solution. The system design process begins with eliciting these requirements and concludes with validating whether the created system meets them. Requirements engineering (RE) encompasses elicitation, representation, analysis, documentation, verification, and validation. However, challenges in RE, such as imprecision in natural language (NL), proprietary restrictions, and a lack of standardized quality metrics, hinder the creation of well-formed and comprehensive requirements. These challenges complicate formalization and analysis of requirements.

This dissertation addresses these challenges by proposing …

Nanostructured Silicon Meta-Waveguides And Surfaces For Enhanced Light-Matter Interaction, Saddam Gafsi

All Dissertations

In this study, we tackle the challenge of light-matter interaction engineering and local field enhancement using various silicon photonic platforms based on three different approaches. (i) The first approach is based on boundary condition engineering where we present and show through simulation and experimental results, a silicon nanodisk “diabolo” configuration able to support significant local field enhancement levels in the range ~102 to 104 in the high index medium through proper structural modifications at the nanoscale. We show that the presented optical behavior is consistent with the anapole modes characterized by the observed near-field enhancement and coinciding with far-field suppression. …

Characterizing Treatment Patterns And Associated Outcomes For Medicare Beneficiaries With Proximal Humerus Fractures, Sydney Lindros

All Dissertations

Proximal humerus fractures (PHF) are a common injury affecting older adults, though clinical decision making for these fractures remains challenging for physicians. Over the past two decades, clinical decision making has evolved with the emergence of new evidence like the ProFHER trial and the dissemination of reverse total shoulder arthroplasty (RTSA). There is a need to characterize the effects of these changes across geographic areas and evaluate the impact of differences in surgical procedure utilization rates on patient outcomes. Therefore, the goal of this dissertation was to gain a better understanding of the utilization patterns and outcomes associated with different …

Protocol Transformations Across Osi Network Stack Layers For Attack, Evasion, And Defense, Nathan Tusing

All Dissertations

Network endpoints frequently contend with errors and deviations within protocols. Many factors account for these deviations including noise, tampering, and algorithm implementations. Intermediate nodes are expected to modify instantiated protocols and not guarantee correctness. This ability to modify traffic enables all sides of network security to alter security and performance properties of protocols, and we define this intermediary modification of an instantiated protocol as a transformation. Protocol transformations traverse layers of the OSI reference model and changes a protocol's time series byte sequence. Within this thesis, we show that this framework applies to multiple domains and protocols. Common examples of …

Emerging Agency In Border Communities During Pandemics, William Ordeman

All Dissertations

“Emerging Agency in Border Communities During Pandemics” uncovers the complex natural and social histories of two Texas border counties, El Paso and Hidalgo, to explain how these counties became highly susceptible to the COVID-19 outbreak in 2020. This work argues that humans engaging with natural resources throughout history created a rhetoric of exploitation and social hierarchy along the Texas/Mexico border. Rhetoric from Spanish and Anglo colonists coupled with environmental phenomena across time displaced Latinx/e bodies living in these counties into precarious communities called colonias, and the presence of these colonias made each county highly susceptible to disease outbreak. I …

Considerable concentrations of cesium-137 (¹³⁷Cs) and other anthropogenic radionuclides have been released into the environment at the Savannah River Site (SRS). Additionally, cesium-containing radioactive waste will be stored onsite for the foreseeable future. Therefore, the goal of this work was to identify mechanisms controlling cesium transport in surface waters and near surface sediments at SRS to further the understanding of ¹³⁷Cs migration in the vadose zone and reservoirs. It was hypothesized that a multitude of factors impact the mobility of ¹³⁷Cs at the SRS, but that the clay sediment fraction provides an important contribution in limiting …

Concert Tickets, Party Matching, Sleeping Barbers, And Single Lane Bridges: Characterizing Student Reasoning About Concurrency, Aubrey Lawson

All Dissertations

Programming with concurrency is challenging both to learn and to teach. A concurrent program has multiple computations happening “at the same time” either simultaneously or in an interleaved manner. It is non-deterministic, imposing only a partial ordering on its decomposed parts. Advantages of concurrency include the potential for increased program throughput, high responsiveness and reduced complexity of program structure. But a concurrent program can be more complex to reason about than a sequential program, in part because the conditions of correctness must hold for all possible execution sequences and also because programmers must implement and reason about synchronization constructs that …

Beryllium Work Area And Tank Waste, Angelica Zarate

Capstone Experience: Master of Public Health

My capstone was conducted at the Hanford site in Richland, Washington. It was once a location that produced weapons-grade plutonium, but now its mission is to clean up the radioactive waste that was left behind. My project focused on beryllium and how much is present in the 56 million gallons of waste that needs to be disposed of. I evaluated the OSHA regulations for beryllium work areas, medical surveillance, and beryllium exposure's environmental and health implications. The purpose was to determine if the concentrations present meet the requirements to continue to be considered a beryllium work area.

The Role Of Serum Total Cholesterol In Coronary Heart Disease: A Prospective Cohort Analysis From The Framingham Heart Study, Sanish Maharjan

Capstone Experience: Master of Public Health

Objective: To investigate the association between serum total cholesterol and coronary heart disease (CHD), accounting for key risk factors in adults aged 32–70 years.

Methods: We analyzed data from 4,382 participants of the Framingham Heart Study, a prospective cohort study with 24 years of follow-up. Multivariable logistic regression was used to assess the relationship between serum cholesterol and CHD, adjusting for age, sex, smoking status, systolic blood pressure, BMI, diabetes, and heart rate.

Results: Individuals with high (aOR = 1.87; 95% CI = 1.52 - 2.32; p<.0001) and borderline high (aOR = 1.40; 95% CI = 1.13 - 1.75; p = 0.0024) cholesterol levels have significantly higher odds of developing CHD than those with normal cholesterol. Older (aOR=1.03; 95% CI=1.03–1.05), male (aOR=2.16; 95% CI=1.86–2.51), current smokers (aOR=1.20; 95% CI=1.03–1.39), hypertensive (aOR=1.88; 95% CI=1.55–2.26), obese (aOR=3.03; 95% CI=1.24–7.43), and diabetic individuals (aOR=2.41; 95% CI=1.63–3.56), had significantly higher CHD risk.

Conclusions: Elevated serum cholesterol significantly increases CHD risk, emphasizing …

The Privacy Act Of 1974: The American Bill Of Rights On Data And Its Unfinished Business, Dongsheng Zang

Articles

In the midst of the artificial intelligence (“AI”) revolution and the debates around it in 2023, this Article proposes to revisit the history of the Privacy Act of 1974, a federal statute that attempted to revolutionize the notion of privacy in response to automated data processing in the computer age. By recognizing that an individual should have the right to control data about herself, the 1974 Act went beyond the Warren-Brandeis framework of privacy based on tort law—the 1974 Act was essentially an American Bill of Rights on data.

The Article first tracks the conceptual development of this new idea …

The Right To Inequality: Conservative Politics And Precedent Collide, Jonathan P. Feingold

Connecticut Law Review

The “end of affirmative action” is the beginning of this story. In Students for Fair Admissions v. Harvard (SFFA), the Supreme Court struck a near fatal blow to race-consciousness. Many institutions have since pivoted to “race neutral alternatives.” This is a natural turn. But one that faces immediate headwinds.

The same entities that demanded Harvard pursue racial diversity through colorblind means have sued public high schools for doing just that. These litigants assert a “right to inequality”—a theory that would pit the Equal Protection Clause against equality itself. Even if normatively jarring, a right to inequality might seem a natural …

Evaluating The Effect Of Education And Follow-Up On Non-Compliance With Positive Airway Pressure Devices Among Male Patients Over The Age Of 50 Years Old, Arthur Mitchell

Doctoral Projects

Negative symptoms of Obstructive Sleep Apnea (OSA) are often the result of preventable circumstance related to the lack of adherence with positive airway pressure device (PAP) use. Research by Gabryelska et al. (2021) notes polysomnography and pap devices are the golden standards of diagnosis and treatment of OSA, yet non-compliance rates average 50% (Askland et al., 2020). Obesity, at times, is seen as a comorbid disorder with OSA, yet is not proven to be the predecessor of OSA. Chronic health conditions such as diabetes, cardiovascular disease can be exacerbated by OSA (Gabryelska et al., 2021). The goal of this doctoral …

Lithotomy And Sitting Positioning: An Objective Structured Clinical Examination, Randall Reece, Jordan Alleman

Doctoral Projects

A foundational skill for anesthesia providers is the ability to safely position surgical patients in a wide variety of surgical positions. Two commonly used surgical positions are the lithotomy and sitting positions. These positions have potential complications that include loss of control of the airway, accidental removal of invasive lines, physiological derangements, soft tissue injury, and nerve injury (Barash et al., 2017). Chui et al. (2018) identified that peripheral nerve injury accounted for 12% of closed claims relating to procedures done under general anesthesia and the most common identifiable event is positioning. The median payout for a peripheral nerve injury …
