Trajectory-Tracking Control Of The Ball-And-Plate System, Dominic E. Riccoboni

Master's Theses

The Mechatronics group in the Mechanical Engineering department of Cal Poly is interested in creating a demonstration of a ball-and-plate trajectory tracking controller on hardware. The display piece will serve to inspire engineering students to pursue Mechatronics and control theory as an area of study. The ball-and-plate system is open-loop unstable, underactuated, and has complicated, nonlinear equations of motion. These features present substantial challenges for control - especially if the objective is trajectory tracking. Because the system is underactuated, common nonlinear trajectory tracking control techniques are ineffective. This thesis lays out a theoretical foundation for controlling the hardware.

Simple Open-Source Formal Verification Of Industrial Programs, Christopher Disney Peterson

Master's Theses

Industrial programs written on Programmable Logic Controllers (PLCs) have become an essential component of many modern industries, including automotive, aerospace, manufacturing, infrastructure, and even amusement parks. As these safety-critical systems become larger and more complex, ensuring their continuous error-free operation has become a significant and important challenge. Formal methods are a potential solution to this issue but have traditionally required substantial time and expertise to deploy. This usability issue is compounded by the fact that PLCs are highly proprietary and have substantial licensing costs, making it difficult to learn about or deploy formal methods on them.

The Vertic Clay Flora Of The San Joaquin Desert: Niche, Competition & Floral Mosaics On A Novel Substrate, Emma R. Fryer

Master's Theses

Plant communities that occur on edaphically heterogeneous landscapes are ideal systems for exploring questions of niche and community assembly. Species with affinity for harsh substrates often have well-defined edaphic niches and are ideal models for testing ecological and evolutionary theory. While plants on substrates such as serpentine and gypsum have received much attention, those on other harsh substrates, including on vertic clay soils, have gone unstudied. Vertic clay soils are both chemically and physically challenging to plant establishment and productivity. Plant communities associated with vertic clay soils of the San Joaquin Desert appear to have a distinctive mosaic pattern of …

Structural Design, Modeling, And Analysis Of The Wing For A World Speed Record-Breaking Turbo-Prop Racing Airplane, Joseph C. Hammond

Master's Theses

The Cal Poly SLO Turbo-Prop Racer (TP Racer) is a vehicle in development with the goal to break the world record for fastest turbo-prop aircraft measured over a 3-kilometer strip. This thesis presents the structural design, modeling, and analysis of the wing of Cal Poly SLO TP Racer. Methodology behind analyzing the wing is presented through finite element modeling elements and a mesh study. This is followed by development of structure through geometry and laminate estimations. The wing structure estimates and loading conditions are then modeled in FEMAP. Initial estimates are analyzed and reviewed – overbuilt, underbuilt, and incorrectly modeled …

Horse Sense Or Horse Hype? Estimating The True Economic Impact Of Churchill Downs And The Kentucky Derby On The Louisville Metro Area, Thomas E. Lambert

Faculty and Staff Scholarship

In trying to assess the true economic impact of the Kentucky Derby on the Louisville region (north central Kentucky and south central Indiana counties), one can find two different estimates appear in doing a quick search on the internet. Some sources, such as the Kentucky Derby Museum, indicate that the economic impact of the Derby is around $217 million (Kentucky Derby Museum 2023) but never mention a source or study for this conjecture. In doing some research, this amount is determined to come from a 2001 study by the marketing research firm Wilkerson and Associates (LaMarra 2001), and therefore this …

Creating Safe Spaces: Diverse Instructional Materials For World Language Learners, Lucian Rothe, Chiann Karen Tsui, Paul A. Garcia, Michael B. Mccloskey

Faculty and Staff Scholarship

Stereotypical notions and depictions of the German language, its speakers, and cultural practices are more persistent in instructional materials, language program advertisements, and people’s minds than one might presume (Bryant et al., 2019; Chavez, 2020a, 2020b; Rothe, 2022). Overcoming such misconceptions requires educators to reconsider curricula and promotional efforts so that they reflect the diverse lived experiences of German speakers and learners (Criser & Malakaj, 2020). To diversify German curricula in the United States, the American Association of Teachers of German (AATG) established a task force in 2020, Creating Safe Spaces (CSS). Its members have developed instructional materials focusing on …

Representations Of Diversity In A Novice-Level Language Classroom And Beyond: An Engaging Semester Project, Lucian Rothe

Faculty and Staff Scholarship

Teacher-scholars have called upon fellow language educators to redevelop curricula at all proficiency levels to portray the lived experiences of target language (TL) speakers. This article presents a semester-long project that contributes to developing diverse teaching materials for college-level learners at the novice level. Via an ePortfolio with 10 tasks (virtual and in-person), 20 learners of a second-semester German course explored connections with the TL locally and broadened their understanding of language-community membership beyond stereotypical notions of native speakers. Participants’ feedback demonstrated how this project positively impacted students’ learning experiences and reflected learners’ strong desire for similar assignments in future …

A Biochemical Necroptosis Model Explains Cell-Type-Specific Responses To Cell Death Cues, Geena V. Ildefonso, Marie Oliver Metzig, Alexander Hoffmann, Leonard A. Harris, Carlos F. Lopez

Biomedical Engineering Faculty Publications and Presentations

Necroptosis is a form of regulated cell death associated with degenerative disorders, autoimmune and inflammatory diseases, and cancer. To better understand the biochemical mechanisms regulating necroptosis, we constructed a detailed computational model of tumor necrosis factor-induced necroptosis based on known molecular interactions from the literature. Intracellular protein levels, used as model inputs, were quantified using label-free mass spectrometry, and the model was calibrated using Bayesian parameter inference to experimental protein time course data from a well-established necroptosis-executing cell line. The calibrated model reproduced the dynamics of phosphorylated mixed lineage kinase domain-like protein, an established necroptosis reporter. A subsequent dynamical systems …

Now You Can Take It With You: Effects Of Occupational Credential Recognition On Labor Market Outcomes, Kihwan Bae, Edward Timmons

Economics Faculty Working Papers Series

Occupational credentials are typically not portable across geography. Using policy reforms by U.S. states, we show that the limited portability of occupational licenses constrains labor market activity and geographic mobility of licensed individuals. After states implement universal recognition, a policy that allows individuals with occupational licenses issued by other states to work without repeating a costly relicensing procedure, we find that the employment ratio increases by 0.98 percentage points among licensed individuals in the sample relative to unlicensed individuals. The employment effect is co-driven by additional labor market participation and a reduction in unemployment after the policy. With the employment …

Emotion Socialization In The Indian Cultural Context, Tripti Kathuria, Shagufa Kapadia Prof., Wolfgang Friedlmeier

Online Readings in Psychology and Culture

The social cultural norms that guide parental practices regarding emotion socialization are determined by cultural meanings ascribed to emotion, emotion expression, regulation, and larger socialization goals. The majority of the empirical research on emotion socialization has been carried out in the US and in Western European countries. The current article aims at understanding emotion socialization in the Indian context interweaving broader views on parenting and socialization, socialization goals, and ancient and modern emotion concepts that shape emotion socialization in India. The heterogeneity of the Indian culture as well as modernization processes that influence these practices suggest heterogeneity of emotion socialization …

Advance Care Planning Is Critical To Overall Wellbeing, Barbara Zabawa

Faculty Works

Wellness is growing market in the United States. McKinsey and Company estimates the spend on wellness products and services to exceed $450 billion in the United States and to grow at more than five percent annually.1 Despite this impressive growth, wellness products and services are falling short of meeting many consumers’ wellness needs.2 Those who feel least satisfied with what wellness has to offer yearn for a more holistic approach to wellness, with a need for more products and services that address sleep and mindfulness concerns.3 Arguably at the heart of these more holistic approaches, particularly those …

(Wp 2023-01) Objectivity In Economics And The Problem Of The Individual, John B. Davis

Economics Working Papers

This paper addresses objectivity in economics. It criticizes a closed science, ‘view from nowhere’ conception of economics and defends an open science, ‘view from somewhere’ conception of objective science. It ascribes the first conception to mainstream economics, associates it with its principle practices – reductionist modeling, formalization, limited interdisciplinarity, and value neutrality – and argues their foundation is the Homo economicus individual conception. Two problematic consequences of adopting this stance are: (i) value blindness regarding the range and complexity of human values; (ii) fatalism regarding human behavior associated with employing a tenseless representation of time. The paper contrasts the principle …

The Impact Of Poverty Informed Faculty On Community College Student Success, Barbara J. Embacher

Department of Educational Administration: Dissertations, Theses, and Student Research

Community college completion has been proven to be a ticket to a middle-class life. Moreover, we know that poverty causes educational barriers, including community college completion. Community colleges across the nation are identifying significant equity gaps between students from poor versus middle-class or affluent households. One solution to close equity gaps and increase student success rates for students experiencing poverty is to educate college faculty through professional development. This includes 1) information on the causes, myths, stereotypes, and other facts about poverty, 2) the impact poverty has on student achievement, and 3) instructional strategies that can help students experiencing poverty …

An Inward Mission Of The Fourth Gospel And Its Reflection In The Ge'ez Rite Divine Liturgy, Brother S. Bdeho

Theses

Various themes of the Fourth Gospel have been explored by scholars. The exploration of its concept of mission and worship is also present. However, the missionary method and its inseparability from worship have not been examined adequately. This thesis examines this unique feature of the Gospel in three major sections. First, the Catholic Church’s contemporary teaching on mission is reviewed based on Ad Gentes (AG) and Redemptoris Missio (RM), which offer the core teaching. The findings show the ad extra missionary praxis is inspired by the s Gospels (AG) while RM shows a move towards ad intra missionary praxis inspired …

Plastic Accumulation In Stormwater Pond Soils Across Socioeconomic And Watershed Development Gradients, Carley Defillips

USF Tampa Graduate Theses and Dissertations

Stormwater runoff is a major vector transporting pollution along the land-to-sea continuum, with the mobilization of nutrient pollution in stormwater runoff being well documented. Although plastic is a pollutant of growing concern, few studies have focused on the potential role stormwater ponds play in mediating plastic transport. This study uses a combination of watershed development and socioeconomic variables to characterize plastic pollution patterns in dry stormwater ponds (those not inundated outside of times of major rainfall) at a watershed scale. Each pond basin was sampled for plastics embedded in the soil and laying on the pond surface using a systematic …

Carceral Socialization As Voter Suppression, Danieli Evans

Articles

In an era of mass incarceration, many people are socialized through interactions with the carceral state. These interactions are poweful learning experiences, and by design, they are contrary to democratic citizenship. Citizenship is about belonging to a community of equals, being entitled to mutual respect and concern. Criminal punishment deliberately harms, subordinates, and stigmatizes. Encounters with the carceral system are powerful experiences of anti-democratic socialization, and they impact peoples' sense of citizenship and trust in government. Accordingly, a large body of social science research shows that eligible voters who have carceral contact are significantly less likely to vote or to …

Modalities Of Social Change Lawyering, Christine N. Cimini, Doug Smith

Articles

The last decade has seen the rise of new kinds of grassroots social movements. Movements including Occupy Wall Street, Black Lives Matter, Sunrise, and #MeToo pushed back against long-standing political, economic, and social crises, including income inequality, racial inequality, police violence, climate change, and the widespread culture of sexual abuse and harassment. As these social change efforts evolve, a growing body of scholarship has begun to theorize the role of lawyers within these new social movements and to identify lawyering characteristics that contribute to sustaining social movements over time. This Article surveys this body of literature and proposes a typology …

Citation, Slavery, And The Law As Choice: Thoughts On Bluebook Rule 10.7.1(D), David J.S. Ziff

Articles

Today, more than 150 years after the end of the Civil War, lawyers and judges continue to rely on antebellum decisions that tacitly or expressly approve of slavery. This reliance often occurs without any acknowledgement of the precedent’s immoral and legally dubious provenance. Modern use of these so-called “slave cases” was the subject of Professor Justin Simard’s 2020 article, Citing Slavery. In response to Professor Simard’s article, the latest edition of The Bluebook includes Rule 10.7.1(d), which requires authors to indicate parenthetically when a decision involves an enslaved person as a party or the property at issue. Unfortunately, Rule 10.7.1(d) …

Defining Intercultural Competence: How Four Pre-Service Teachers Developed A More Complex Understanding Of Icc, Elizabeth C. Barrow

Journal of Global Education and Research

This manuscript is one part of a larger exploratory collective case study of pre-service teachers who participated in a student teaching abroad program for one-month in Germany. The objective was to ascertain if and how pre-service teachers with no prior training in intercultural competence (ICC) developed both their understanding and conceptualization of ICC. Data was collected before, during, and after the experience via focus groups, individual interviews, journal entries, and program evaluations. Data was analyzed using a priori codes compiled from Bennett’s (2008) characteristics of affective, cognitive, and behavioral competencies of ICC. Findings from this study indicated that a short-term …

Perceptions Of Leadership Styles In International Special And General Education Schools In The United Arab Emirates, Kaitlin M. Jackson

Journal of Global Education and Research

Given that school leadership styles are linked to educational outcomes, this study attempted to identify perceived leadership styles of school leaders in two types of schools in the United Arab Emirates (UAE): (a) international special education schools, which serve exclusively students with disabilities and (b) international general education schools, which serve primarily typically developing students. By utilizing primarily quantitative methods with supplementary qualitative analysis, this study also explored the influence of teacher demographic variables on perceptions of leadership styles. Results indicated a difference in perceptions of transformational and transactional leadership by school type based on teacher education level, as well …
