Civil Engineering ETDs

Pedestrians and bicyclists, known as Vulnerable Road Users (VRUs), are disproportionately affected by crashes. Arterial roads significantly impact crash rates, especially for VRUs. Previous research has identified factors contributing to VRU crash frequency. However, limited research focused on the relationship between these factors and VRU crashes in New Mexico, a state with high fatality rates for VRUs. This study aims to answer three research questions: i) Are high-speed, high-access roads more likely to experience crashes than roads with better access management? ii) Do more driveways per mile correlate with more VRU crashes per mile? iii) What other factors related to …

Incorporating Point Of Care Ultrasound In Cardiac Arrest And Pulseless Electrical Activity, Zayneb H. Ghazle

Theses

For decades, cardiac arrests have had a high mortality and morbidity rate despite medical interventions. Statistically, shockable rhythms (ventricular fibrillation, ventricular tachycardia) have had a better prognosis than non-shockable rhythms, which includes pulseless electrical activity (PEA) and asystole¹. The reversible mechanical causes of PEA and the role of point-of-care cardiac ultrasound (POCUS) in their diagnosis and management will be discussed. This paper also focuses on the appearance and interpretation of these sonographic findings in order to guide clinicians in their medical management, goal of returning spontaneous circulation (ROSC), and estimating patient prognosis.

Reflective And Dialogical Approaches In Engineering Ethics Education, Lavinia Marin, Yousef Jalali, Alexandra Morrison, Cristina Voinea

Michigan Tech Publications

This chapter addresses the challenges of implementing reflective thinking in engineering ethics education (EEE). It examines existing methods for teaching ethical reflection in EEE and argues that pedagogical activities aiming to foster ethical reflection need to be infused with dialogical interactions and, at a deeper level, informed by dialogism. Dialogism is understood as a relational approach to inquiry in which interactions between moral agents enable them to develop their own understandings through the process of finding shared meanings with the others in activities such as sharing reasons and deliberation. Drawing on pragmatism and phenomenology, the authors conceptualize reflection as a …

Ownership Topology Of Vertically-Scaled Agile, William Dabney

Theses

Much as Scrum, Kanban, and XP are used to structure team-level agility, those wishing to take agility beyond the team level often turn to proven solutions. The most popular, which aim to scale development by adding teams under a shared collective ownership rather than separating them into discrete units, are the Scaled Agile Framework (SAFe), Large Scale Scrum (LeSS), and Nexus. These frameworks advocate for aligning ownership subdivisions along features rather than code, which allows teams working on the same product to do so autonomously. While the benefits of this have been researched, the topology of ownership in these frameworks …

Florescence, Evan D. Jaccodine

Theses

Florescence is a photographic project that provokes conversation between mediums, methods, and attitudes in art and design. Starting as grainy, screened Risograph prints mounted into custom wood frames, the uniformity of mechanical reproduction is distorted by handmade craft elements. The images examine the materiality of making as part of the message they produce; they are both eclectic handmade objects and mass-produced products. These pictures intend to communicate an idea like an advertisement, except the message, meaning, or intention isn’t clear. I am interested in the moment when the viewer comes close enough to the image to see the prints' poor …

Tunable And Parabolic Piezoelectricity In Hafnia Under Epitaxial Strain, Hao Cheng, Peijie Jiao, Jian Wang, Mingkai Qing, Yu Deng, Jun-Ming Liu, Laurent Bellaiche, Di Wu, Yurong Yang

Physics Faculty Publications and Presentations

Piezoelectrics are a class of functional materials that have been extensively used for application in modern electro-mechanical and mechatronics technologies. The sign of longitudinal piezoelectric coefficients is typically positive but recently a few ferroelectrics, such as ferroelectric polymer poly(vinylidene fluoride) and van der Waals ferroelectric CuInP₂S₆, were experimentally found to have negative piezoelectricity. Here, using first-principles calculation and measurements, we show that the sign of the longitudinal linear piezoelectric coefficient of HfO₂ can be tuned from positive to negative via epitaxial strain. Nonlinear and even parabolic piezoelectric behaviors are further found at tensile epitaxial strain. …
