Vibro-Acoustic Analysis Of A Fan Blade, Matthew Koithan

2022 Spring Honors Capstone Projects - Archive

A frequent problem with rotating machinery is vibration. Vibration in a rotating part can be caused by unequal mass distribution. A sound or acoustic wave is created by a pattern or disturbances traveling through a medium. Vibration and Acoustics can be dealt with individually, however, if they share a common source, both could be solved simultaneously. The purpose of this project is to correlate the fan noise to the rotor imbalance. The unbalanced mass can be removed by aligning the center of gravity (CG) with the axis of rotation, which eliminates any coupled moments. The vibration is measured using accelerometers …

Computational Modeling Of Post-Surgical Hypertrophic Heart For Surgical Planning, Sudhir Pandit

2022 Spring Honors Capstone Projects - Archive

Hypertrophic cardiomyopathy (HCM) is a clinically prevalent disease in people around the world, with potential outcomes ranging from sudden cardiac arrest and/or heart failure to the normal life expectancy of the patients. HCM is a condition where the interventricular septal wall becomes abnormally larger, making it difficult for the heart to pump blood from the left ventricle. The current gold standard for the treatment of HCM is Cardiac Myectomy, in which the overgrown tissues are resected to correct the heart and restore the blood flow. Due to the complex anatomy of the heart and anatomical differences in the internal structures …

Impact Of Stability And Control On Vehicle Geometry And Performance: A Design Study On Traditional Hypersonic Vehicles Vs Controlled Configured Hypersonic Vehicles, Juan Camilo Buritica Yate

2022 Spring Honors Capstone Projects - Archive

Hypersonic vehicles have been in development for over 60 years, yet a control-configure-vehicle has yet to be designed to understand the possible improvements over statically stable configurations. This paper studies the effect of stability and control on aircraft geometry and performance by comparing traditional vehicles versus control configured vehicles (CCV) that operate at subsonic and supersonic speeds and extrapolates this analysis to predict these effects on hypersonic vehicles. Data related to geometry, aerodynamic performance, and stability from various vehicles were collected and used to find trends by comparing aircraft design parameters to stability criteria. The results showed that by decreasing …

Gender Differences In Perception Of Dyspnea And Its Relation To Muscle Weakness, Functional Status, Disability In Activities Of Daily Living, And Depression In Adults With Heart Failure—A Secondary Analysis, Michelle Minh Tran

2022 Spring Honors Capstone Projects - Archive

Although Heart Failure (HF) can occur in both women and men, some studies have shown that both genders do not present the same outcomes; however, there is an underrepresentation of the effect of gender on the relationship of HF and changes in activities of daily living. This study compared the effects of gender on dyspnea and other variables to determine differences between symptoms, disability, and other relationships. A secondary analysis of a cross-sectional descriptive study was conducted with 186 patients who were told to perform several tests to evaluate muscle weakness, functional status, depression, and disability.

SES significantly associated with PA, obesity, crime …

Study Of Neutrino Background For The Low-Mass Dark Matter Search In Future Neutrino Experiments, Aayush Bhattarai

2022 Spring Honors Capstone Projects - Archive

With high-intensity neutrino beams and large mass detectors, neutrino physics has entered the high precision measurement era. Accelerator experiments that use high-intensity proton beams impinging on a fixed target could produce dark matter along with neutrinos. DUNE, one of the most extensive neutrino experiments under construction, has similar prospects of looking for low-mass dark matter (LDM) produced in the proton interactions with the target. With the possibility of charge-neutral LDM production in the target, numerous neutrinos will be generated alongside it, which will be the primary background to the LDM signal. To understand these neutrino backgrounds, we studied two “modified …

Destroying Man: Philosophically Situating C. S. Lewis’ The Abolition Of Man, Anna Elizabeth Tarpley

2022 Spring Honors Capstone Projects - Archive

Lewis’ central argument in The Abolition of Man explains the philosophical consequences of extending assumptions implicit within scientific methodologies and originally used to treat Nature to include a treatment of humans. This thesis elucidates Lewis’ philosophical concept of man’s “Power Over Nature” by providing the historical and philosophical context out of which it developed. Multi-disciplinary research relying on primary source documentation, secondary academic literature, biographical material, and philosophical text was used to synthesize a descriptive philosophical narrative in two parts. The first part consists in the historical basis for the shift in ideas involved in Lewis’ argument as manifest in …

United Nations Peacekeepers, The Use Of Sexual Exploitation And Abuse, And Feminist Theory, Corrina Marie Sullivan

2022 Spring Honors Capstone Projects - Archive

Why do United Nations peacekeepers enact sexual harm against the very populations they are meant to protect? Given that the purpose of United Nations peacekeepers is to promote peace in a country following a period of unrest and/or violence, acts of sexual exploitation and abuse are antithetical to their purpose. These acts also inflict trauma on populations meant to be protected. Finally, this behavior undermines the general trust in the United Nations. Therefore, when peacekeepers engage in acts of sexual exploitation and abuse, these acts have larger implications for not only the peacekeeping force but the United Nations as a …

A Study Of Algorithmic Bias With A Focus On Mitigation Practices And An Analysis Of Discrimination Conscious Data Mining, Ashni Walia

2022 Spring Honors Capstone Projects - Archive

Algorithmic bias is a moral error within computer systems that is often left undetected due to a lack of set procedures. The aim of this study was to find the source of this bias leading to possible procedural solutions that can be applied widely. A meta- analysis, case study, and sample interview statistics are used to understand the multiplication of such bias into generated outputs. The study concluded that lack of diverse data leads to bias in output, in addition to a lack of awareness about the existence of such bias. This ignorance is amplified by the myth surrounding deep …

The Effect Of Depression, Anxiety, And Length Of Stay In Neonatal Intensive Care Upon Maternal-Infant Bonding, Tori Shavon Young

2022 Spring Honors Capstone Projects - Archive

Bonding is important to establish an early relationship but a challenge to mothers with infants in NICU. The aim of this study was to determine if a longer length of time an infant requires NICU admission is associated with impaired maternal-infant bonding. A secondary goal explored associations and effects of maternal depression and anxiety upon bonding via the Postpartum Bonding Questionnaire (PBQ), Edinburg Postnatal Depression Scale (EPDS), and a subscale of the EPDS for anxiety. A descriptive design was used to explore mental health and bonding among 45 NICU mothers who were at least 18 years old and could speak, …

Agricultural Carbon: The Land, Landowner, And Farmer, Barclay Rogers

Journal of Food Law & Policy

Carbon is certainly a hot topic in agriculture. Across the countryside, farmers, landowners, agricultural service providers, and many others are trying to understand what carbon is about and what it may mean to them. One of the more interesting topics around agricultural carbon concerns the relationship between the landowner and tenant farmers on absentee-owned land (i.e., land that is farmed by someone other than the person who owns it). This article provides a brief background on the agricultural carbon opportunity and explores some ideas about how to pursue the opportunity on absentee-owned farmland.

Black-Owned Beef: Should Black Beef Producers Stake Space In Food Justice?, Shirah Dedman

Journal of Food Law & Policy

While there is growing interest in Black cowboys, the narrative is largely tethered to parades and urban and suburban saddle clubs, much like the fictional movie on Netflix, Concrete Cowboy. Missing from the narrative are today’s real Black cowboys: rural ranchers and farmers raising cattle for beef production and consumption.

The Broken Beef Cattle Industry: Cool, Covid And Cattletrace, Hayden L. Ballard

Journal of Food Law & Policy

While the Kansas City Stockyards themselves are gone, just like in the early 20th Century, a beef monopoly has once again found its way into the industry, and a way around the Packers and Stockyards Act of 1921 and is again suffocating the industry. While at the time of the act’s passage in 1921 five companies controlled the market, today the market is even more consolidated in the “Big Four,” as the four biggest meat packing companies in America are commonly known (Cargill, Tyson, JBS and National Beef/Marfrig), and are again arguably stifling the free-market. If Americans do not act …

Plantain Cultivation In Puerto Rico: Its Inclusion In The National Crop Table Of The United States Department Of Agriculture’S Farm Service Agency, And Its Loss Compensation In Disaster Programs, Javier A. Rivera-Aquino

Journal of Food Law & Policy

If justice is to provide each person what they deserve, it seems plantain producers in Puerto Rico did not relish a just compensation for their farm losses after Hurricane Maria in 2017. The main culprit? Stale data. Farm Service Agency’s (FSA) Wildfire and Hurricanes Indemnity Program (WHIP) utilized plantain production data under the National Crop Table (NCT) 2017, which seemingly did not reflect up-to-date yield averages of Puerto Rico’s plantain farmers at the time of Hurricane Maria.

Interjurisdictional Abortion Wars In The Post-Roe Era, Maya Manian

Scholarly Articles in Law Reviews & Journals

The Supreme Court appears poised to overrule fifty years of precedent holding that pre-viability prohibitions on abortion are unconstitutional. In a leaked draft opinion of Dobbs v. Jackson Women Health Organization, Justice Alito proclaims that Roe v. Wade and Planned Parenthood v. Casey must be overruled and abortion left to the states to regulate. During oral argument in Dobbs, Justice Kavanaugh suggested that overturning Roe would return the Court to a postion of "neutrality" on abortion. Justice Kavanaugh's assertion falls in line with claims by anti-abortion jurists that reversing Roe would simplify abortion law by returning the issue to the …

With an estimated five-year survival of less than 40 percent, angiosarcomas are rare and often misdiagnosed fataltumors originating from blood or lymphatic vessels with a predilection for the head and neck. They account for 1percent of all soft tissue sarcomas and are often mistaken for benign mimickers leading to the late-stage diagnosiswhen the body is already riddled with metastatic disease with the lung being the most common site of metastases.This case illustrates the myriad of pulmonary complications associated with this uncommon but fatal vasoformativemalignancy. The patient is a 73-year-old male diagnosed with angiosarcoma of the right scalp status post excision,reconstruction, …

An Exploratory Study On Refactoring Documentation In Issues Handling, Eman Abdullah Alomar, Anthony Peruma, Mohamed Wiem Mkaouer, Christian D. Newman, Ali Ouni

Articles

Understanding the practice of refactoring documentation is of paramount importance in academia and industry. Issue tracking systems are used by most software projects enabling developers, quality assurance, managers, and users to submit feature requests and other tasks such as bug fixing and code review. Although recent studies explored how to document refactoring in commit messages, little is known about how developers describe their refactoring needs in issues. In this study, we aim at exploring developer-reported refactoring changes in issues to better understand what developers consider to be problematic in their code and how they handle it. Our approach relies on …
