Predictability Of The Overland Reintensification Of North Atlantic Tropical Cyclone Erin (2007), Ariel Tickner-Ernst

Theses and Dissertations

Tropical cyclones (TC) typically decrease in intensity upon interacting with land because of increased surface roughness and decreased surface evaporation. However, several studies have documented cases in which TCs maintain their intensity or even intensify over land within non- or weakly baroclinic environments. Yet, our understanding of the precise physical processes that support maintenance or intensification over land in non- or weakly baroclinic environments remains limited, and the predictive skill for these outcomes has yet to be quantified.

We begin this process by quantifying the predictive skill and forecast uncertainty of the overland intensification of North Atlantic Tropical Storm Erin …

Milwaukee’S Electric Scooter Program: A Review And Analysis Of A Municipal Pilot Study Of A Shared Micromobility Program, Lexie Nehmer

Cities are implementing shared micromobility to provide on-demand transportation options. Shared micromobility services have gained popularity in recent yeas as an efficient and sustainable mode of transportation in urban areas such as Milwaukee. Privately-owned modes, such as electric scooters, are being integrated into urban planning and local policies as a convenient option for short-distance travel. The introduction of technology supported, shared micromobility services has improved transport equity by filling in network gaps. Cities look at how e-scooters conveniently fit into a multimodal transportation plan and how they serve a positive public purpose without negatively impacting the public right of way. …

Games And Time, Evelynn Kersting

Theses and Dissertations

Video games are a medium uniquely immersed in time. While the topic of time and games has been broached by many in the field of game studies, its centrality to both how games function and the experience of playing games remains underexamined. Reading games as literary texts, this holistic study uses queer and social theories to survey the myriad of ways games play with time. I argue games are time machines, each idiosyncratically allows players to experience time differently from traditional linear time. Beyond games with literal time machines, this dissertation examines games which structure themselves around labyrinthine and existential …

The Impact Of Medical Device Usability And Accessibility Information On Purchasing Decisions Of People Without Disabilities, Maysam M. Ardehali

Theses and Dissertations

The disparity between people with and without disabilities in timely diagnosis and appropriate treatment is exacerbated by inaccessible medical devices. The industry appears reluctant to address the shortcomings or provide usability and accessibility information to enhance the purchasing decisions of people with disabilities. This reluctance is mainly caused by the lack of market motivation based on perceptions of market size and the profitability of investments in accessibility evaluation and improvement. This study aims to challenge this notion by demonstrating that usability and accessibility information do not solely benefit what may be considered a “niche market,” and the purchasing decisions of …

Imagery In Nasca Cross-Knit Looped Textiles From The Milwaukee Public Museum, Katherine A. Cianciola

Theses and Dissertations

Textiles associated with the Nasca culture (0-650 C.E.) from Peru’s South Coast have been recognized for their complex and colorful ecological, anthropomorphic, and geometric imagery. Little, however, has been written about their three-dimensional cross-knit looping and embroidery. Cross-knit looping produced three-dimensional figures that were part of an elaborate border on clothing and a style specifically associated with the Nasca (Sawyer 1997:24, 27, 41, 97, 131-132, 136 for example). This thesis focuses on Nasca textiles primarily from the Malcolm K. Whyte (Accession Numbers: 18046 and 20517) collection at the Milwaukee Public Museum (MPM) and includes three-dimensional cross-knit looping of ecological and …

Combinatorial Problems Related To Optimal Transport And Parking Functions, Jan Kretschmann

Theses and Dissertations

In the first part of this work, we provide contributions to optimal transport through work on the discrete Earth Mover's Distance (EMD).We provide a new formula for the mean EMD by computing three different formulas for the sum of width-one matrices: the first two formulas apply the theory of abstract simplicial complexes and result from a shelling of the order complex, whereas the last formula uses Young tableaux. Subsequently, we employ this result to compute the EMD under different cost matrices satisfying the Monge property. Additionally, we use linear programming to compute the EMD under non-Monge cost matrices, giving an …

Optimizing The Synthesis Process For Lithium-Ion Sieve Adsorbents: Effect Of Calcination Temperature And Heating Rate On Reaction Efficiency And Performance, Calvin Nyambane Nyarangi

Theses and Dissertations

Processing-structure-property relationships play a crucial role in tuning the performance of materials for a given application in order to attain a suitable set of optimal conditions, therefore, it is imperative to evaluate the parameters of either the synthesis, delithiation, adsorption, and desorption process. Through an orthogonal test design of the solid-state synthesis process, it was determined that a heating rate of 1 ℃/min had consistently higher reaction efficiencies of 68.1 %, 68.6 %, and 72.3 % at the calcination temperatures of 650 ℃, 700 ℃, and 750 ℃ respectively compared to heating rates of 4 ℃/min and 7 ℃/min.

Elucidating Aposematic Patterns In North American Hylids, Joseph S. Cannizzaro Iv

Theses and Dissertations

Recognizing form and function of animal defenses is paramount to understanding the ecological and evolutionary forces behind predator and prey dynamics. Color patterns are strongly related to defensive strategies in animals. Some rely on camouflage to avoid detection, while others are brightly colored and conspicuously signal their noxiousness to potential predators. Still others combine cryptic dorsal coloration with colorful patches that are concealed in resting position but are facultatively unveiled by special behavior or simply during activity. Such hidden conspicuous color patches may be an intermediate stage in the evolution from camouflage to aposematism. We investigated whether conspicuously colored thighs …

Biomolecular Function From Structural Snapshots, Roshanak Etemadpour

Theses and Dissertations

Biological molecules can assume a continuous range of conformations during function. Near equilibrium, the Boltzmann relation connects a particular conformation's free energy to the conformation's occupation probability, thus giving rise to one or more energy landscapes. Biomolecular function proceeds along minimum-energy pathways on such landscapes. Consequently, a comprehensive understanding of biomolecular function often involves the determination of the free-energy landscapes and the identification of functionally relevant minimum-energy conformational paths on these landscapes. Specific techniques are necessary to determine continuous conformational spectra and identify functionally relevant conformational trajectories from a collection of raw single-particle snapshots from, e.g. cryogenic electron microscopy (cryo-EM) …

Methodology To Investigate Protein-Protein Interactions Of Jun During Neuronal Differentiation Of Pc12 Cells, Heather L. Leskinen

Theses and Dissertations

In humans and other mammals, injury to the central nervous system (CNS) can cause a permanent loss of neuronal function, leading to cognitive defects, limb paralysis, and other neurological disabilities. In contrast, studies have shown that some non-mammalian vertebrates like zebrafish, have the remarkable ability to functionally regenerate axons after CNS injury by reactivating and sustaining the expression of regeneration-associated genes (RAGs). Some RAGs encode transcriptional regulators that dimerize to control downstream gene expression necessary for functional axonal recovery. Our lab has previously identified Jun as an important transcriptional regulator of regeneration after optic nerve injury in zebrafish. After axon …

Theses and Dissertations

This thesis explores deep learning methods for Human Activity Recognition (HAR) from videos to automate the annotation of human activities in videos. The research is particularly relevant for continuous monitoring in healthcare settings such as nursing homes and hospitals. The innovative part of the approach lies in using YOLO models to first detect humans in video frames and then isolating them from the rest of the image for activity recognition which leads to an improvement in accuracy. The study employs pre-trained deep residual networks, such as ResNet50, ResNet152-V2, and Inception-ResNetV2, which were found to work better than custom CNN-based models. …

Toward Truth And Reconciliation: Public Memory, Philosophical Pairs, And The Edmund Pettus Bridge, Allyson K. Hayden

Theses and Dissertations

This thesis connects the rhetoric of Bryan Stevenson which advances truth and reconciliation for racial healing in the United States to a case study of the Edmund Pettus Bridge in Selma, Alabama. I examine common cultural invocations of the bridge that support the persistence of a blurry public memory that occludes visibility of its original memorial dedication to a known white supremacist and instead celebrates it as a landmark of the civil rights movement. I also analyze arguments for both changing and keeping the name of the bridge that occurred between 2015-2020, illustrating ways in which Perelman and Olbrechts-Tyteca’s philosophical …

Theses and Dissertations

This thesis studies how Mexican Americans living in the northwest suburbs of Chicago produce connections to their Mexican heritage and culture through the performance of ballet Mexicano folklórico. Through ethnographic interviews of current and former folklórico dancers, as well as participant observation of adult folklórico dance practices, I contextualize the experiences of the interviewees using the anthropological theories of habitus, continuous and discontinuous selves, double-consciousness, liminality, and collective effervescence, as well as the works of Simone de Beauvoir, Michel Foucault, and Frantz Fanon, with the discussion of folklórico as an art, and the concept of institutional use of dance as …

Beyond Their Smiling Faces: Reconstructing The Remojadas Ritual And Culture Through The Sonrientes Figurines From The Mpm Collection, Abigail Munoz

Theses and Dissertations

Sonrientes (Smiling Faces) scholarship has waned after a brief period of archaeological interest in the mid to late 20th century by both Spanish and English language scholars. Since then, brief attention to these figurines in the Remojadas style, or similar, has been given when discussing the Classic Period on the Gulf Coast and few direct studies on their interpretation or reinterpretation have been given within the last few years. The present study attempts to contribute my own interpretation of these Remojadas-style figurines and answer five major questions driving my research: What kind of rituals did Remojadas or other people carry …

School Crisis Response: Perceptions Of Experienced Responders, Travis E. Pinter

Theses and Dissertations

The needs of a school community following the death of a student or staff member are not something every educator and/or school administrator may be prepared to address. Multi-disciplinary crisis response teams, particularly those operating at the district level, are equipped to respond to such situations rapidly and effectively. School psychologists, due to their categorization as “scientist practitioners” in the educational environment and their training in both therapeutic intervention models and tiered service delivery, are especially qualified to coordinate training for, manage, and serve on K-12 crisis response teams. Unfortunately, the definitive manualized program on school crisis response, PREPaRE (Brock …
