Fault-Tolerant High-Power Two-Phase Coreless Afpm Motor-Drive System Concept, Yaser Chulaee, Ali Mohammadi, Matin Vatani, Aaron M. Cramer, Dan M. Ionel

Electrical and Computer Engineering Graduate Research

This paper proposes a fault-tolerant, high-power two-phase coreless axial flux permanent magnet (AFPM) motor drive system concept. Initially, the performance of a two-phase variant of the coreless AFPM machine is compared with that of its three-phase counterpart using both 3D finite element analysis (FEA) and experiments. Thanks to the intrinsic unique features of coreless AFPM machines, the analysis of the results demonstrates that the two-phase configuration has comparable power density (kW/kg) and efficiency. In terms of fault tolerance, the two-phase configuration exhibits superior performance, as the mutual inductance between phases is zero, resulting in an electric machine with magnetically decoupled …

The optimization process is implemented on two distinct designs: a 20-pole inner rotor PM-excited stator machine and a 28-pole outer rotor DC-excited stator machine. Analysis results demonstrate that the proposed innovative method significantly reduces torque ripple in both configurations. Force …

Electromagnetic Design Characterization Of Synchronous Machines With Flux Switching Effect Employing Reluctance Rotors And Stators With Pms And Ac Concentrated Coils, Oluwaseun A. Badewa, Ali Mohammadi, Donovin D. Lewis, Somasundaram Essakiappan, Madhav Manjrekar, Dan M. Ionel

Electrical and Computer Engineering Graduate Research

This paper introduces an innovative design for a synchronous electric motor that has phase coils and permanent magnets (PM) embedded in the stator. The electric machine contains both concentrated winded phase coils in dedicated slots and spoke-type permanent magnets solely in the stator. The spoke-type magnet arrangement achieves a high flux intensity even with low remanence non-rare earth permanent magnets. As the rotor has no active electromagnetic components, the risk for demagnetization is reduced and advanced cooling applied to the stator can enable high-speed operation. The principle of operation and polarity of the motor are investigated with a unique approach …

Addressing The "Hidden Crisis" In Doctoral Education: Identifying The (De)Motivating Effects Of Memorable Messages From A Self-Determination Theory Perspective, Alexis A. Murphy

Theses and Dissertations--Communication

Although PhD students are academically capable, they paradoxically produce alarmingly high attrition rates. For several years, retention rates in PhD programs have averaged between 40% and 70% (Ames et al., 2018; Bowen & Rudenstine, 1992; Cochran et al., 2014; Gardner & GoPaul, 2012; Lovitts, 2001; Rockinson-Szapkiw & Spaulding, 2012). Scholars have presented several potential reasons that PhD students discontinue their studies, none of which include academic ability (Lovitts, 2001; Tucker, 1964; Sverdlick et al., 2018). Framed by self-determination theory (SDT), this study explores the social and communicative components of the doctoral education system by the psychological impact of memorable messages …

Virtual Speeches, Real Fears: Public Speaking Anxiety In The Online Communication Classroom, Timothy J. Bill

Theses and Dissertations--Communication

While universities have explored online course offerings for decades, the COVID-19 pandemic accelerated this trend. The foundational communication course—a course that continues to traditionally emphasize public speaking—has felt the pandemic influence to increase opportunities for students to learn public speaking via online instruction. While scholars have learned much about the student experience of public speaking anxiety (PSA) in face-to-face settings, less is known about their experience of PSA in online courses. This dissertation explored the fears students experience when presenting online and how they view the online presentation environment.

Using Bandura’s Social Cognitive Theory as a guide, this dissertation employed …

"The Lgbtq Community, That's My New Church": An Examination Of Lgbtq+ Former Church Members' Experiences Of Religious Exit, Samantha N. Pfeiffer

Theses and Dissertations--Communication

This study examines the experiences of LGBTQ+ individuals who previously attended Independent Fundamentalist Baptist (IFB) churches, considering their experiences of being in the church, leaving the church, and rebuilding outside of the church. It also examines sermons from IFB churches that addressed topics related to the LGBTQ+ community to examine the teachings these individuals received while in the church. My examination of this topic was based in scholarly literature addressing the rhetoric of church sermons, the process and experience of religious disaffiliation, and Weick’s (1995) theory of organizational sensemaking. I used multiple qualitative methods in this study, including qualitative content …

The Information Practices Of Undergraduates Encountering Material Objects As Information Resources In Classroom Learning Tasks, Christopher A. Miller

Theses and Dissertations--Communication

Undergraduate students sometimes encounter material objects as information resources in small-group classroom learning activities. Examples include art, artifacts, specimens, and anatomical models. This dissertation sought to identify common features of the students’ information practices in such situations, regardless of the activity’s discipline or content, and to explore how making material information central shapes students’ information practices. The conceptual framework combined theorizations of materiality and information practices. Methods involved video recording students doing a variety of simulated classroom activities with objects, video elicitation, qualitative content analysis, and praxiographic interpretation. The praxiographic interpretive descriptions illustrated how all aspects of the site–material, bodily, …

Player 2 Has Entered The Culture War: Discourse, Ideology, And Narrative In Gamergate 2.0, Ashley C. Mccann

Theses and Dissertations--Communication

My thesis addresses the ever-evolving landscape of Gamergate 2.0. Once a reactionary misogynistic harassment movement dedicated to attacking women in video games, the new iteration of Gamergate has evolved into an entirely new community. In its new iteration, Gamergate is even less ostensibly concerned with video games and more with reactionary content, mixing together nerd media, general pop culture, and right-wing politics. To study this community, I approach the Gamergate 2.0 community as an anti-fandom and reactionary affinity space. I argue that GamerGate 2.0 exists as its own powerful reactionary community that creates a worldview consisting of the desired destruction …

Spaced Learning Approaches To Attitude Change: Impressions Of Individuals, Outgroup Prejudice, And Policy Endorsement, Emily Grace Ritchie

Yale Graduate School of Arts and Sciences Dissertations

How does the schedule of information delivery influence attitude change? While decades of research highlights the cognitive benefits of spaced learning for memory, little is known about whether these same principles extend to the domain of persuasion— particularly for socially meaningful or politically charged attitudes. This dissertation bridges cognitive and social psychological approaches by investigating whether spacing persuasive content over time enhances its ability to revise attitudes. Across three empirical chapters, I test the effects of spaced versus massed presentation of new information on evaluative judgements in three distinct domains: person impressions, social group attitudes, and policy support. In Chapter …

Ponnusamy, Maneesh Jain, Mokenge Malafa, Santhamma Bindu, Ahmed Gulzar, Hareesh Nair, Surinder K. Batra, Sushil Kumar

Journal Articles: Biochemistry & Molecular Biology

Pancreatic ductal adenocarcinoma (PDAC) is inherently therapy resistant due to cancer cell-stroma crosstalk across several signaling pathways. Among these, the LIF/LIFR axis has been implicated in cancer cell and cancer-associated fibroblast (CAF) crosstalk. We evaluated the efficacy of EC359, a competitive inhibitor of LIFR, in combination with gemcitabine. EC359 reduced tumor burden by 90% compared to controls and by 55% compared to gemcitabine alone in cancer cell and CAFs co-implannation model. The RNA-seq analysis revealed a significant alteration in extracellular matrix components, stemness, microtubule assembly, and immune response, suggesting simultaneous targeting of cancer cell-intrinsic and stroma-mediated mechanisms by EC359. In …

Mumford Relations And The Cohomology Of Le Potier Moduli Spaces, Weite Pi

Yale Graduate School of Arts and Sciences Dissertations

The goal of this thesis is to study the cohomological aspect of Le Potier’s moduli space of 1-dimensional sheaves on the projective plane. Our main technical tools are Mumford-type geometric relations, formulated originally over moduli of bundles on curves and generalized to sheaves over del Pezzo surfaces in this thesis. We prove that these relations can be obtained effectively from certain primitive ones via the Virasoro operators. As applications, we prove a minimal generation result, a cohomological χ-dependence result, and fully compute the cohomology rings in low degrees. Finally, we propose a “Perverse = Chern” conjecture relating two filtrations …

Essays In Economic Theory, Ferdinand Manuel Pieroth

Yale Graduate School of Arts and Sciences Dissertations

My dissertation examines the role of information acquisition and other frictions in bargaining and contracting settings. Chapter 1 studies an informal common value auction where a seller controls buyers' access to costly information. It shows that allowing the winning bidder to acquire information after bidding, i.e., via due diligence, maximizes the seller’s worst-case payoff when stakes are sufficiently high. Chapter 2 analyzes competition between firms selling a homogeneous good to a rationally inattentive consumer. It identifies an attention effect, whereby competition increases trade engagement. As a result, firms’ aggregate profits are increasing in the number of active firms …
