Parameter Estimation Of A 100 Seater Simulated Passenger Aircraft, Michael James Winston Jan 2025

Parameter Estimation Of A 100 Seater Simulated Passenger Aircraft, Michael James Winston

Graduate Theses, Dissertations, and Problem Reports (ETD)

Virtual flight test aircraft provide good opportunities to test new parameter estimation methods. However, good estimates for the parameters in VIRTTAC Castor, a virtual test aircraft, are unavailable. This thesis uses two well-established time domain methods, the Output Error Method and the Filter Error Method, to estimate the parameters of VIRTTAC Castor. Three standard maneuvers were used: Elevator 3-2-1-1, Rudder Doublet, and Aileron Multi-Step. The parameters were estimated across three different flight conditions: weight, altitude and air speed, which resulted in 27 tests for each maneuver. All parameters, and standard deviations estimated are included in the appendix as a table.

Genetic Variation Of Rice Stink Bugs, Oebalus Spp. (Hemiptera: Pentatomidae) From Southeastern United States And Cuba, Allen Szalanski

Entomology and Plant Pathology Faculty Publications and Presentations

The rice stink bug, Oebalus pugnax (F.; Hemiptera: Pentatomidae) has been a pest of rice in the United States since the 1880s. Besides this species, there now are two invasive Oebalus species, O. ypsilongriseus (De Geer) and O. insularis Stål, which are found in Florida. Genetic variation of these economically important species is unknown, limiting our understanding of Oebalus evolution and demography. Here we provide the first population-level investigation of genetic diversity in these species. Ninety two adult stink bugs were collected from the southeastern United States (Arkansas, Mississippi, Florida), and Cuba. A region of the mitochondrial DNA cytochrome oxidase …

Pain For Pain: The Benefits And Challenges Of Bdsm Participation For People With Chronic Pain–An Exploratory Study, Reni Forer, Bryce Westlake

Faculty Research, Scholarly, and Creative Activity

Research is beginning to find that many BDSM (bondage/discipline, domination/submission, sadism/masochism) practitioners experience benefits beyond sexual pleasure. Additionally, given the relationship between pain and pleasure common in BDSM, there may be certain unanticipated benefits for practitioners reporting chronic pain (PRCP). We conducted an online survey of an international convenience sample of BDSM practitioners (N = 525). Participants were asked about self-perceived benefits and challenges related to participating in BDSM with CP. Using chi-square, independent sample t-test, logistic regression, and linear-by-linear association, responses were combined with demographics, participation timelines, co-participants, motivations, and frequency of activities to identify differences between PRCP and …

Normalizing Facial Recognition Technology And The End Of Obscurity, Woodrow Hartzog, Evan Selinger, Judy Hyojoo Rhee Jan 2025

Normalizing Facial Recognition Technology And The End Of Obscurity, Woodrow Hartzog, Evan Selinger, Judy Hyojoo Rhee

Faculty Scholarship

This article argues that facial recognition technology is the most dangerous surveillance tool ever invented. Given the unique threats this morally suspect tool poses to privacy, civil liberties, human flourishing, and democracy, the only appropriate response is a ban. To justify our position, we explain why facial recognition is distinctive among biometrics, clarify how even seemingly benign and positive uses of the technology can trigger dangerous normalization dynamics, and pinpoint why current United States laws (with reverberations in the EU’s AI Act) are designed to accelerate a slippery slope that makes mass surveillance nearly inevitable. Our most fundamental contribution lies …

Policing Gender: The Interest Convergence Of Women's And Transgender Rights, Michael Ulrich Jan 2025

Policing Gender: The Interest Convergence Of Women's And Transgender Rights, Michael Ulrich

Faculty Scholarship

The social, political, and legal landscape has seen a resurgence of gender fundamentalism, seeking to reinforce archaic notions of what it means to be a woman. Social media movements run in tandem with this resurgence of gender fundamentalism. For instance, the “tradwife” phenomenon that romanticizes a domestic, subservient role for women.1 Alabama Senator Katie Britt most infamously reflected the convergence of these trends when she delivered her response to the State of the Union from a kitchen table and proclaimed that her message was “a direct appeal” to her “fellow moms.”2 Meanwhile, executive orders and state laws have …

Challenging The Law, Steven Arrigg Koh Jan 2025

Challenging The Law, Steven Arrigg Koh

Faculty Scholarship

Frédéric Mégret’s engaging contribution, A Look Back at The Women’s Hague Peace Conference: What Contribution To International Law Today?, exposes a legal duality. On one hand, the legalist perspective: law is a closed system. From this perspective, law is objective, hard, universal, and bounded. On the other hand, the sociocultural perspective: law is a human practice. From this perspective, law is subjective, organic, particular, and porous. This Essay reads Mégret’s analysis of the 1915 International Congress of Women in The Hague as a “sociocultural challenge,” disrupting the legalist perspective on international law, war, and peace during World War I. …

Do Academic Researchers Care About Patent Infringement? A Pcr Case Study, Janet Freilich Jan 2025

Do Academic Researchers Care About Patent Infringement? A Pcr Case Study, Janet Freilich

Faculty Scholarship

Because much cutting-edge academic research involves building on other new technologies, university research often involves making or using a patented invention—an act of patent infringement. The problem of how patents affect academic researchers has attracted considerable attention, but legal scholars are divided on the magnitude of patents’ potential impact. Many scholars fear that patents will entirely hobble academic scientific research, while others find that academic researchers entirely ignore patents and thus that they have little impact. This Article adds a piece of empirical evidence to the debate by studying the example of polymerase chain reaction (PCR) technology. In the early …

Under What Circumstances Is "Caste" Likely To Be Useful As An Analytic Concept (And Should We Care)?, Sanford V. Levinson, Robert L. Tsai Jan 2025

Under What Circumstances Is "Caste" Likely To Be Useful As An Analytic Concept (And Should We Care)?, Sanford V. Levinson, Robert L. Tsai

Faculty Scholarship

This Essay is the product of the 2025 “Constitutional Law Schmooze,” where academics from a variety of disciplines and from all over the country meet to discuss a common topic of constitutional law chosen by the moderator. This year’s topic was “caste.” The two of us, having written independent “tickets” of admission for the schmooze—i.e., short essays setting out our tentative thoughts about “caste”—turned out to be relative skeptics about the value of the term for lawyers. We are certainly not hostile to those who differ with us. This should be regarded as a “friendly dissent,” as distinguished, say, from …

What We Should Know About The Reliability Of Empirical Legal Studies, Kathryn Zeiler Jan 2025

What We Should Know About The Reliability Of Empirical Legal Studies, Kathryn Zeiler

Faculty Scholarship

The findings of replication studies conducted in the early 2010s led many to declare that science was in the midst of a “replication crisis.” Since then, a growing number of reforms have been proposed and tested. The field of empirical legal studies seems behind other fields such as psychology, economics, political science, medicine, biology, and others that have taken significant steps toward uncovering the general reliability of the field’s empirical work, investigating the causes of observed unreliability, and instituting and testing the effects of various reforms. The purpose of this Article is to summarize what we know about the reliability …

A Multifactorial Approach To Improve Piglet Health And Survival, Aryeri Stephanie Bardales Castellanos Jan 2025

A Multifactorial Approach To Improve Piglet Health And Survival, Aryeri Stephanie Bardales Castellanos

Electronic Theses and Dissertations

Pre-weaning mortality (PWM) remains a significant challenge in modern swine production systems, particularly in the context of hyper prolific sows. Although genetic selection has successfully increased litter sizes, these advancements have also intensified physiological stress on sows and increased the vulnerability of neonatal piglets. The majority of PWM occurs within the first 72 hours postpartum, with crushing by the sow as the leading cause of death. Additionally, iron deficiency anemia remains one of the most widespread nutritional disorders in piglets, further compromising survival, immune function, and growth. This thesis adopts a multifactorial approach to evaluate two management interventions aimed at …

In The Footsteps Of Moose: Using Non-Invasive Techniques To Identify Cause-Specific Calf Mortalities And Evaluate Moose (Alces Alces) Movements Pertaining To Mineral Lick Locations On Ancestral Lands Of The Grand Portage Ojibwe, Anna B. Weesies

Electronic Theses and Dissertations

Following a sharp moose (Alces alces; mooz, Anishinaabemowin, Ojibwe language) population decline in northeastern Minnesota during the early 2000s, the Grand Portage Band of Lake Superior Chippewa initiated a long-term moose collaring effort to assess survival and mortality causes. Moose are a culturally important species to the Band, with annual subsistence hunts held on the Reservation and adjacent 1854 Ceded Territory. Continued research guides culturally appropriate management decisions aimed at bolstering calf and adult survival, helping to preserve this moose in Minnesota today and for subsequent generations. Chapter 1 identifies cause-specific calf mortality rates in this multi-predator system using minimally …

The Formation And Degradation Of Carboxysomes During Heterocyst Development In Filamentous Cyanobacteria, Maxwell Anton Jakubiak Jan 2025

The Formation And Degradation Of Carboxysomes During Heterocyst Development In Filamentous Cyanobacteria, Maxwell Anton Jakubiak

Electronic Theses and Dissertations

Photosynthetic carbon (CO2) fixation and solar-powered nitrogen (N2) fixation are foundational biochemical processes that introduce essential elements into the biosphere. While atmospheric dinitrogen gas (N2) is unusable to most organisms, diazotrophs utilize the nitrogenase enzyme to reduce N2 to ammonia. Because all known nitrogenases are highly susceptible to irreversible oxygen inactivation, N2 fixation is generally incompatible with oxygenic photosynthesis. However, several cyanobacteria are both photosynthetic and diazotrophic, balancing these opposing metabolisms by temporally or spatially separating the respective enzymes. Anabaena sp. PCC 7120 is a model multicellular cyanobacterium that grows in filaments of photosynthetic vegetative cells, which respond to nitrogen …
