Emergency Vehicle Prioritization In Connected And Autonomous Traffic., Mohamadreza Haghani

Electronic Theses and Dissertations

Reducing the response time of emergency vehicles (EV) is highly important due to the relationship between response time and fatality rate. Emerging technologies can help reduce response time by enhancing EV prioritization. On the other hand, EV prioritization can negatively impact general traffic especially in cross streets of signalized intersections. In this research, three main objectives were followed. Firstly, creation and dissipation of EVP disruption on arterial cross streets was studied to recommend solutions to prevent this disruption. Secondly, lane-changing and stopping behavior of CAVs were studied in EV prioritization to identify the best lane-changing behavior through minimizing delay. Thirdly, …

A Design Science And Implementation Framework For Studying Interruptions And Its Application In A Dental Clinic., Carsten Ziegler

Electronic Theses and Dissertations

Interruptions during dental treatment are frequent, and often have detrimental effects on quality of care, patient safety and processing times, and have an impact on provider satisfaction and performance. Interruptions can significantly increase the cognitive load on dental providers, making it hard for them to concentrate on complex procedures. Frequent interruptions also disrupt the workflow in general, leading to delays in treatment, which can reduce the overall throughput of a clinic. Unfortunately, there is no comprehensive approach to collectively (i) analyze interruptions in dental healthcare, (ii) design an intervention, and (iii) implement and sustain it. This research proposes a comprehensive …

W.E. B. Du Bois And Audre Lorde's Pan-African Development: Remedies For The Problem Of Othering., J.E. Young

Electronic Theses and Dissertations

W.E.B. Du Bois and Audre Lorde’s Pan-African Development: Remedies for the Problem of Othering is an Afrocentric reading of Black U.S intellectual traditions of self-definition from the late 19th to early 21st century. I argue that W.E.B. Du Bois and Audre Lorde adhered to two major Afrocentric principles: balance and justice. At the root of these principles is the understanding that binaries constructed as oppositions create unjust hierarchies. My theoretical approach is attuned to the distinct ways that Du Bois and Lorde communicated the importance of self-definition and Africana spirituality in relationship to other Black intellectual thought. Placing them in …

Investigation Of Avaren-Fc's Therapeutic Potential Against Ovarian Cancer., Katarina Lee Mayer

Electronic Theses and Dissertations
