Modeling and Failure Analysis of Tubular Braided and Filament Winding Composite Structures
No full textThe central objective of this master’s research is to develop and analyze two types of carbon fiber-reinforced composite structures—Filament Winding and Braided Winding—for the application in hydrogen storage vessels. This work focuses on the geometric modeling of these textile structures and explores how their structural parameters influence the mechanical performance and failure modes of the resulting composite vessels. Both composite structures studied in this thesis are based on Fiber Reinforced Polymer Composites (FRPCs). The thesis is organized into three main chapters. Chapter One provides a concise overview of the types, applica- tions, and current research trends surrounding textile FRPC structures, emphasizing their role in advanced energy storage technologies. Chapter Two presents a kind of geometrical modeling method and applies finite element framework to analyze braided winding structures, investigating how braid angle affects overall structural response. Chapter Three details the finite element modeling approach developed for filament winding composite structures, with a particular focus on the influence of winding angles, winding pattern, and other key geometric parameters on mechan- ical behavior and failure mechanisms. The outcomes of this study offer valuable insights into the design and optimization of carbon fiber compos- ite structures for hydrogen storage applications
Integrating U-Net and LLM Agents for Pancreatic Ductal Adenocarcinoma Diagnosis
No full textColor poster with text, images, charts, and graphs.This study proposes an AI driven pipeline that combines, pancreas segmentation outcome for Pancreatic Ductal Adenocarcinoma (PDAC) diagnosis with a large language model (LLM) agent to enhance diagnostic and clinical analysis. Building upon already established deep learning approaches in medical imaging, our project aims to extend traditional UNet segmentation methods by integrating the capabilities of an LLM agent to provide detailed diagnostic information for medical practitioners. Using the Pancreas Decathlon dataset, 3D CT scans are processed and trained over multiple different iterations utilizing attention mechanisms, sparse categorical cross entropy and Tversky loss. The predicted segmentation labels are used by the LLM to infer diagnostic details such as the stage of the disease progression and integrate results with the electronic health records for longitudinal study. Ultimately, this integrated framework aims to assist medical practitioners in diagnosing PDAC more effectively while offering additional supplemental information.UW-Eau Claire Foundation; Mayo Clinic; University of Wisconsin--Eau Claire Office of Research and Sponsored Program
Mechanical Properties of Organic-Inorganic Composite Films : Comparing the Impacts of Flexible vs. Rigid Organic Components
No full textColor poster with text, images, charts, and graphs.A series of organic-inorganic composite films composed of close-packed, alkanethiol-capped gold nanoparticles and rigid, aromatic dithiol crosslinking molecules were assembled upon the air-water interface within a Langmuir trough. The mechanical properties of films were assessed by the Langmuir isotherm, yielding measurements of minimum collapse pressures and structural responses to collapse. The results of this study address the individual roles of nanoscale materials components, further enabling the rational design of nanoarchitectures with specific chemical, physical, and mechanical properties.American Chemical Society- Petroleum Research Fund, PRF # 57391-UR10; University of Wisconsin--Eau Claire Office of Research and Sponsored Program
CAPTIVE SUBJECTS: ART AND PHOTOGRAPHY AT THE LONDON ZOO, 1828-1914
No full textThe London Zoo was founded in 1828 and quickly became London’s premier site for viewing non-indigenous animals. Not long after, in 1839, photography emerged and evolved alongside the Zoo. While the London Zoo had already established itself as being cooperative with artists working in traditional media (e.g. painting, printmaking, sculpture), photography played a limited role in this practice until the late nineteenth century. This thesis examines the Zoo as a locus of artistic production and witness to a gradual transition in primacy from traditional media to photography. I discuss the major photographers working in this genre and their methodologies, arguing that the challenging conditions of zoo photography drove innovation, acting as a stimulus for emerging photographic technologies. I provide context for the rise of photography with discussion of artists working in zoological illustration and animal painting. When the Zoo began officially mobilizing photography in the early twentieth century, I argue that the institution took advantage of the ostensible objectivity of the medium to enhance its reputation and perhaps obscure failures in animal husbandry
An analysis of the advantages and disadvantages of using youdao electronic dictionary applications in English language learning among high school students in China
No full textA seminar paper presented to the graduate faculty at the University of Wisconsin-Platteville.
In partial fulfillment of the requirement for the degree of Master of science in education - English educationThe purpose of this study is to investigate the effectiveness of the application of YoudaoDictionary in Chinese high school students' English learning, especially its role in vocabularyacquisition and learning outcomes. With the popularization of smartphones and their influenceon educational tools, electronic dictionaries, especially Youdao Dictionary, have become animportant aid for students to learn English. This paper analyzes the functional features of theYoudao Dictionary and its practical application in different types of schools through a
combination of literature analysis and case study. The study shows that Youdao Dictionary significantly improves students' vocabulary learning efficiency through the functions of speech recognition, example analysis and personalized learning. However, over-reliance on dictionaries may lead to insufficient in-depth language learning, especially when facing high-pressure exams such as the college entrance examination, where students may rely more on dictionary tools than on the real learning process. Through the analysis of different school types (differential
application in key high schools, general high schools and private high schools), this paper points out that the guiding role of teachers is crucial to maximize the benefits of learning with the word dictionary. In addition, this study proposes individualized teaching strategies based on
geographical differences and differences in school types to promote the optimal use of electronic dictionaries in high school English teaching
Socialized Silence of Students of Color in Community College Composition Classes
No full textFull Text DissertationThis hermeneutic phenomenological study was designed to analyze the experiences of Students of Color with socialized silence in community college composition classes. The research sought to understand both the impacts of socialized silence on Students of Color and their descriptions of the composition instructors’ curriculum, behaviors, and practices that created or perpetuated that silence. Participants were Students of Color at the Community College of Aurora in Aurora, Colorado who had completed a composition course in the prior academic year and who self-reported as having experienced socialized silence. Participants were interviewed twice in a semi-structured format. The resulting data was thematically analyzed through the theoretical framework of Culturally Sustaining Pedagogy. The study concluded that Students of Color are impacted by race-evasive and White centering practices and behaviors that impose silence and create harmful classroom environments where Students of Color must self-silence for protection. Recommendations are made for the institution, curriculum, instructors, students, and future research. Notable in the recommendations are ways to decenter Whiteness and to center Culturally Sustaining Pedagogy (CSP). Culturally Sustaining curriculum and pedagogy have the potential to disrupt these silencing structures and empower voice, creating spaces where Students of Color can become transformative agents of change
Bearing Witness: A Point Against Functionalist Linguistic Metaethics
No full textOn occasion, we are morally called to bear witness—often to atrocities, tragedies, and suffering, but also to the good, the beautiful, and the admirable, to the reality of rich and flourishing human living. Bearing witness and its attendant speech acts play integral roles in our moral practices. But importantly, the moral value in bearing witness and its attendant speech acts is not exhausted by the value in changing others’ minds. This poses a problem for certain interpretations of moral language deployed in deflationist, quasi-realist accounts of metaethics, and particularly in Karl Schafer’s (2012) picture of assessor-relative perspectivalism. Schafer responds to an objection from disagreement with a broadly functionalist framework: moral language is valuable because it can lead to the coordination of our moral perspectives. I challenge Schafer’s account of moral language by looking at paradigm speech acts of bearing witness whose full value, I maintain, cannot be illuminated by a purely functionalist view. Bearing witness is just a particularly clear counterexample to the functionalist account—it is by no means the only one. Our moral language in general is shot through with a similar structure. This problem generalizes to any account that cashes out the value of moral disagreement purely in perspectival coordination or grounds moral language on assertion. I therefore pose an important challenge to functionalism about moral language by building an account of bearing witness and working towards a theory of moral perception and moral language more generally
The 'motivation codes' and academic keys of group collaboration at different language proficiency levels in China
No full textA seminar paper presented to the graduate faculty at the University of Wisconsin-Platteville.
In partial fulfillment of the requirement for the degree of Master of science in education - English educationThis paper mainly focuses on the problems of art class learning for Chinese high school students. The English proficiency of these art students varies greatly, and the traditional standardized teaching does not take into account the different English proficiency among students, which is unfair and disadvantageous to students.
This study employs a combined approach of cooperative learning and action research, grouping students based on their varying English proficiency levels. It uses methods tailored to the learning characteristics and thinking patterns of art students to explore how teachers can optimize group strategies. Data were collected through classroom observations, questionnaires, and interviews, employing a mixed-methods approach to analyze the effectiveness of grouping and the impact of action research. While previous studies have acknowledged the benefits of cooperative learning, this study focuses on Chinese art students and their specific needs, filling a gap in related research. The findings can provide effective teaching methods for classrooms with significant differences in student English proficiency. However, the study also has limitations, such as being confined to high schools in China, not considering non-level grouping methods, and the applicability of the results being influenced by environmental factors
Evaluating the role of dialectical behavior therapy (DBT) in reducing recidivism: Success factors and best practices in correctional settings
No full textA seminar paper presented to the graduate faculty at the University of Wisconsin-Platteville.
In partial fulfillment of the requirement for the degree of Master of Science - Criminal JusticeThis research examines the high need for correctional facilities to implement dialectical
behavior therapy (DBT) programming. Secondary research was conducted of articles, websites,
and past and present DBT programming, to show the significant cognitive behavioral changes
DBT programming can have on maladaptive patterns of behavior resulting in documented
recidivism reduction amongst program participants. Analytical data has shown cognitive
behavioral programming has some of the greatest impact on the incarcerated population with the
potential to reduce recidivism by twenty to thirty percent. This paper also highlights the current
gaps and barriers within the current correctional system that prevent incarcerated persons from
having the access or opportunity to participate in DBT programming. Without this targeted
programming, incarcerated persons are less likely to effectively address the root of their
maladaptive behaviors which often leads to reincarceration, increasing recidivism rates, and
continuing the cycle of trauma
