Team Air Combat Using Model-Based Reinforcement Learning, David A. Mottice

Theses and Dissertations

We formulate the first generalized air combat maneuvering problem (ACMP), called the MvN ACMP, wherein M friendly AUCAVs engage against N enemy AUCAVs, developing a Markov decision process (MDP) model to control the team of M Blue AUCAVs. The MDP model leverages a 5-degree-of-freedom aircraft state transition model and formulates a directed energy weapon capability. Instead, a model-based reinforcement learning approach is adopted wherein an approximate policy iteration algorithmic strategy is implemented to attain high-quality approximate policies relative to a high performing benchmark policy. The ADP algorithm utilizes a multi-layer neural network for the value function approximation regression mechanism. One-versus-one …

Development Of A Methodology For The Quantification Of Reaerosolization Of A Biological Contaminant Surrogate Particle From Military Uniform Fabric, George D. Cooksey

Theses and Dissertations

During a mass casualty medical evacuation after a bioaerosol attack, a decontamination method is needed that is effective at both decontamination and preventing the secondary hazard of biological particles reaerosolizing from contaminated clothing. However, neither the efficacy of current decontamination methods nor the risk of biological particle reaerosolization is significantly explored in existing literature. The goals of this thesis were to develop a repeatable methodology to quantify the reaerosolization of a biological contaminate off Airman Battle Uniform (ABU) fabric swatches, and to test the efficacy of one decontamination method (high-volume, low-pressure water) using 1 mpolystyrene latex (PSL) spheres as a …

Theses and Dissertations

Members of the armed forces greatly rely on having an effective and efficient medical evacuation (MEDEVAC) process for evacuating casualties from the battlefield to medical treatment facilities (MTF) during combat operations. This thesis examines the MEDEVAC dispatching problem and seeks to determine an optimal policy for dispatching a MEDEVAC unit, if any, when a 9-line MEDEVAC request arrives, taking into account triage classification errors and the possibility of having blood transfusion kits on board select MEDEVAC units. A discounted, infinite-horizon continuous-time Markov decision process (MDP) model is formulated to examine such problem and compare generated dispatching policies to the myopic …

Care Ethics, Bruno Latour, And The Anthropocene, Michael Flower, Maurice Hamington

Philosophy Faculty Publications and Presentations

Bruno Latour is one of the founding figures in social network theory and a broadly influential systems thinker. Although his work has always been relational, little scholarship has engaged the relational morality, ontology, and epistemology of feminist care ethics with Latour’s actor–network theory. This article is intended as a translation and a prompt to spur further interactions. Latour’s recent publications, in particular, have focused on the new climate regime of the Anthropocene. Care theorists are just beginning to address posthuman approaches to care. The argument here is that Latourian analysis is helpful for such explorations, given that caring for the …

Analysis Of Microscopic Carbon Fiber Fragments, Zachary R. Scott

Theses and Dissertations

Carbon Fiber (CF) has different tensile strengths and transverse moduli depending on how they are fabricated. Some CF is export controlled as it can be used for weapons, spacecraft, or gas centrifuges for enriching nuclear fuel. This research project explored a new way to prepare micron sized single CF threads to measure their transverse modulus and compare the moduli of non-export controlled CF to that of an export controlled CF. Five total polyacrylonitrile (PAN) fibers were used in this project, one of which was an export controlled fiber.

Does Restoration Of Urban Riparian Zones Impact Stream Water Quality In Portland, Oregon, Ash Ivanov

University Honors Theses

Riparian zones influence urban stream quality through factors such as shading the stream, adding nutrients through leaf litter, stabilizing the stream banks to reduce turbidity, and filtering toxins out of the water. Riparian restoration often involves changing plant assemblage to be more diverse and include primarily native species instead of non-native, improving connection to the stream through changing stream morphology, improving species habitat, and reducing pollution. The goal of this study was to determine if urban riparian restoration projects in the region were successful, and if not, why that may be the case. The study was performed in the Portland, …

Gender Does Not Equal Genitalia: A Review Of The Implications Of Inclusivity In School-Based Sexual Health Education On The Identity Development Of Non-Binary And Transgender Adolescents, Sol N. Rise

University Honors Theses

Abstinence-only based sexual education has historically been the predominant form of school-based sexuality and sexual health education in the United States since the early 1900s. In recent years, there has been an emergence of more expansive and inclusive comprehensive education, however, both types of sexual education continue to affirm hetero- and cis-centric social and cultural norms around gender and sexual identity that leave transgender and non-binary youth at increased risk of poor psychological well-being and physical health outcomes compared to their peers. There have been considerable recommendations within the discourse community for the linguistic de-gendering of anatomy and anatomical processes, …

Perversion: A Genealogy Of Deviance And Creation Of The "Other", J D. Lyell

University Honors Theses

Drawing from Thomas Aquinas' Theory of Natural Law, I investigate Euro-Christian conceptions of naturalness and unnaturalness and how they were weaponized to cast racialized groups as perverse in the construction of the United States. I focus on the enforcement of Euro-heteropatriarchy to demonize Indigenous family and gender structures, as well as the characterization of Black bodies as abnormal by white academia to demonstrate some of the ways gender and sexuality have been colonized in the U.S. My research provides a general outline tracing a genealogy of deviance as established by Euro-Christian norms of sexuality and gender, which emerges from a …

Views On Aging – Current Trends And Future Directions For Cross-Cultural Research, Anna E. Kornadt, Clara De Paula Couto, Klaus Rothermund

Online Readings in Psychology and Culture

The investigation of what enables societies and individuals to age well remains one of the greatest challenges of our time. Views on aging are a decisive factor in this process, and thus, improving their understanding through cross-cultural research is of utmost importance. In the current review, we address the role of socio-ecological variables and cultural values and beliefs when investigating country differences in what people think about older persons and getting old themselves. Several complexities are introduced in terms of a differentiated conceptualization of views on aging that takes life domains and normative prescriptions into account, and also in terms …

The Full Monty: Analyzing The Constitutionality Of Ordinances That Only Punish Women For Being Topless In Public, Max Birmingham

Southern Illinois University Law Journal

Public female-only topless bans are constitutional, as most courts have upheld. This Article addresses two concerns surrounding the equal protection clause of the Fourteenth Amendment: First, whether an ordinance expressly punishing women—but not men—for being topless in public violates the Equal Protection Clause; and second, whether an ordinance targeting women and criminalizing exposure of “the female breast” is unconstitutional.

The Equal Protection Clause makes no distinction between classifications (sex, race, ancestry, alienage, inter alia) and other discriminatory practices. Nor does the text require equal treatment or equal rights. Rather, it requires equality only in the “protection of the laws.” Female …

It is necessary to predict the future Boro rice production in accordance with CC as well as take supplementary actions to ensure …

Clash And Cooperation Of Ecofeminism And Postmodern Feminism: The Intersection Of Two Theories In Dystopic Literature, Ashton Koch

Honors Program: Senior Projects (Public)

Ecofeminism and postmodern feminism are regarded as opposite theories in their attempts to solve for ecological and patriarchal oppression. This thesis argues that these two theories are not mutually exclusive, and must work together to effectively combat oppression faced by the environment and by women. It uses two works of literature, Our Life in the Forest by Marie Darrieussecq and Oryx and Crake by Margaret Atwood to argue for the combination of ecofeminist and postmodern feminist strategies. Both works are dystopic in nature, portraying the destruction of the environment and patriarchal discourse against women. Ultimately, this thesis analyzes the strategies …

Relating Metabolic Phenotypes To Movement Behavior In Brook Trout, Jacob E. Bowman

All NMU Master's Theses

Brook trout movement-related life history strategies vary considerably and range from individuals that stay within the same 100 meters their entire life to individuals that are potamodromous or anadromous. Potential drivers of movement life histories have been the subject of much research in fish, with genetic subpopulation explanations often failing to explain the phenomenon. Metabolic phenotypes have been suggested as a possible driver for expression of different movement life histories. I investigated if metabolic phenotypes are related to movement strategies within a population of brook trout (Salvelinus fontinalis) in Unnamed Creek, a tributary to the Rock River, Alger …

Trafficking Without Borders: Why It Is Time For The Law To Properly Address Cybersex Trafficking In The Livestreaming Context, Jesse Raines

Catholic University Law Review

This Comment assesses the impact, and growing prevalence, of cybersex trafficking: A relatively novel form of human trafficking conducted via livestream over the internet. In particular, this Comment focuses on the differences between the statutes that criminalize sex trafficking and child pornography and how these statutes operate both domestically and internationally. This Comment argues that the Trafficking Victims Protection Act of 2000 should be amended in order for the modern crime of cybersex trafficking to fall under the statute’s ambit and to aid in prosecution efforts.
