Narrative of nonviolence: An autoethnographic journey towards nonviolence in education
No full textThis autoethnographic dissertation examines the transformative power of nonviolence in education through the lens of the author's lived experience. Through reflective narrative inquiry, the study examines how personal experiences, including childhood in a rural school, early motherhood, and professional challenges, inform the author’s understanding and practice of nonviolence. The study reveals how personal narratives can inform the understanding, development, and implementation of nonviolent educational practices. Key themes include the transformation of conflict into opportunities for growth, the integration of mindfulness in personal and professional spheres, and the importance of vulnerability in fostering nonviolent relationships. The study situates the author's experiences within a broader framework of nonviolence theory, and the findings suggest that nonviolence is not merely the absence of harm but a proactive approach to nurturing compassion, empathy, and understanding in schools. The implications of this research extend to educational leaders, policymakers, and practitioners, advocating for a curriculum that prioritizes nonviolent principles and practices. By weaving together personal narrative and academic discourse, this research contributes to the growing body of knowledge on nonviolence in education by offering practical insights for educators and policymakers seeking to implement transformative practices in their educational settings where every individual feels valued and respected

Heights of polynomials over lemniscates
No full textWe consider a family of heights defined by the Lₚ norms of polynomials with respect to the equilibrium measure of a lemniscate for 0 ≤ p ≤ ∞, where p = 0 corresponds to the geometric mean (the generalized Mahler measure) and p = ∞ corresponds to the standard supremum norm. This special choice of the measure allows to find an explicit form for the geometric mean of a polynomial, and estimate it via certain resultant. For lemniscates satisfying appropriate hypotheses, we establish explicit polynomials of lowest height, and also show their uniqueness. We discuss relations between the standard results on the Mahler measure and their analogues for lemniscates that include generalizations of Kronecker’s theorem on algebraic integers in the unit disk, as well as of Lehmer’s conjecture.Mathematic
Dynamic phasor-based framework for accelerated power system simulation via adaptive time stepping
No full textTransient analysis is essential for understanding the behavior of power systems under various contingencies. However, due to the size and complexity of power systems, coupled with their wide timescale dynamics, detailed transient analysis is often computationally prohibitive. Consequently, simplified device models are typically used for large-scale analysis.This thesis investigates the potential of dynamic phasor (DP) based modeling to accelerate simulation speeds while retaining detailed models. Various DP formulations exist in the literature, and this work aims to consolidate these methods and revisit the theoretical foundations of DP-based schemes. To accelerate transient analysis, we combine DP-based modeling with adaptive time-stepping in numerical integration. This approach achieves a computationally efficient simulation framework without losing detail while maintaining high numerical accuracy. Our analysis demonstrates that DP-based modeling can achieve varying levels of detail in simulations without requiring model-level modifications. To explore this framework, a simulation platform using the Julia programming language is developed. Numerical issues impacting the computational stability of the simulation are identified, and remedial strategies are presented. A validation case study using the single-machine infinite-bus system is conducted, with results compared to the electromagnetic transient simulation tool PSCAD and quasi-steady-state (QSS) simulation tool ANDES. An additional case study using the IEEE-14 bus system is performed. The results indicate that DP-based modeling achieves computational speeds comparable to QSS simulation tools, with highly accurate simulation results. This suggests that detailed information about system trajectories can be obtained using DP-based modeling framework with equal or less computational effort as compared to QSS simulation
Passing to play: Examining student-athlete academic motivation
No full textStudent-athletes at all levels are tasked with managing academic success and athletic performance simultaneously. Many of these students may only achieve passing grades in order to remain eligible to participate in their sport. This is when the idea of “passing to play” comes about (Lapchick, 1989). To gain insight on this, I conducted a survey with Oklahoma high school students who are or were student-athletes, and the professionals who work with these students. Within the survey it asks for demographic information and questions about their academic performance and its relationship to their athletic participation. It also included the opportunity to be interviewed and answer further questions to examine personal motivations and influences on academic performance. This study was conducted and once the data was collected, it was coded for common themes across the participants' answers. Knowing what motivates this population of students can influence teaching practices, administration, and school policies, as well as how teachers, coaches, and other staff members frame academics in relation to these students’ athletic endeavors. By understanding how students are motivated, their experience and success in school can be improved.Lew Wentz FoundationTeaching, Learning and Educational Science
Sustainable power-to-gas system design: Integrating renewable energy storage and environmental responsibilty
No full textPower-to-gas exists as a potential solution to the difficulties encountered when storing and utilizing excess renewable energy. In order to evaluate the economic viability of a power-to-gas system as tasked by AIChE, a methanation reactor, purification skid, and storage system were designed. The proposed design utilizes carbon dioxide captured from ammonia production that is processed in combination with hydrogen from renewably powered electrolysis units. The design was constructed with an emphasis on inherent safety principles and overall process safety through simplification of design, proper pressure relief, and minimization of hazardous storage. A Piping and Instrumentation Diagram (P&ID) of the reactors and cooling loop provides a detailed control strategy and accompanies a Process Flow Diagram (PFD) of the entire process. A discussion of potential ways to make the system economically attractive, including the potential for location dependence and government subsidies, was explored

Role of air sealing while ground source heat pump system retrofits in U.S. single-family houses
No full textWidespread commercial adoption of ground source heat pumps (GSHP) is hindered by the relatively high initial cost associated with drilling boreholes in the ground to deploy ground heat exchangers. Reducing the energy demand of buildings has the potential to reduce the required borehole length and the associated drilling costs. In single-family residential buildings, air sealing can significantly lower heating energy usage, according to recent studies and reports. Thus, air sealing in conjunction with GSHP retrofits can lower the required GSHP system's capacity and borehole length to meet the thermal demands of the buildings. In order to understand the role of combining air sealing with GSHP retrofit quantitatively, the current study employs a whole building energy simulation tool integrated with an advanced design tool for the ground heat exchanger to determine changes in required GSHP capacity, total borehole length, and building energy consumption for with- and without-air sealing in single-family houses in 3 climate zones in the United States. The study considers one representative city for each climate zone, Phoenix, AZ for a hot climate, Seattle, WA for a moderate climate, and Minneapolis, MN for a cold climate. The results from this study show that reducing air infiltration from 0.8 ACH to the minimum ventilation requirement (0.35 ACH) can reduce borehole length requirement by up to 24% in Phoenix, 32% in Seattle, and 70% in Minneapolis. A similar magnitude of reduction can be seen for GSHP capacity and total building energy usage as well
