Description
Classical pianists have struggled to reconcile personal artistic growth with the economic and cultural realities of a career as a musician. This paper explores the existing structure of North American undergraduate piano education and its development alongside sociological and cultural changes in the twentieth century. Through document study and interviews, I look at three different models of undergraduate piano curricula. Chapters One and Two explore the issues and history surrounding the traditional piano curriculum. Chapters Three and Four draw on interviews to study two different North American undergraduate curricula: a piano curriculum within a liberal arts environment of an American Conservatory-College, and a piano curriculum within a Canadian University Faculty of Music. Chapter Five concludes with a summary of these findings and potential recommendations for implementation. In this study, I suggest that changes to piano curricula were made because of a differing approach, one in which music is seen as an entrepreneurial vocation. These changes point to a discrepancy between what is being provided in the curriculum, and the actual skills that are needed in order to thrive in today's economy. Awareness of the constant flux of the current professional climate is necessary in order for pianists to channel their skills into the world. I theorize that changes in curricula were made in order to provide a better bridge for students to meet realistic demands in their career and increase their ability to impact the community.

Description
There has been a vast increase in applications of Unmanned Aerial Vehicles (UAVs) in civilian domains. To operate in the civilian airspace, a UAV must be able to sense and avoid both static and moving obstacles for flight safety. While indoor and low-altitude environments are mainly occupied by static obstacles, risks in space of higher altitude primarily come from moving obstacles such as other aircraft or flying vehicles in the airspace. Therefore, the ability to avoid moving obstacles becomes a necessity
for Unmanned Aerial Vehicles.
Towards enabling a UAV to autonomously sense and avoid moving obstacles, this thesis makes the following contributions. Initially, an image-based reactive motion planner is developed for a quadrotor to avoid a fast approaching obstacle. Furthermore, A Dubin’s curve based geometry method is developed as a global path planner for a fixed-wing UAV to avoid collisions with aircraft. The image-based method is unable to produce an optimal path and the geometry method uses a simplified UAV model. To compensate
these two disadvantages, a series of algorithms built upon the Closed-Loop Rapid Exploratory Random Tree are developed as global path planners to generate collision avoidance paths in real time. The algorithms are validated in Software-In-the-Loop (SITL) and Hardware-In-the-Loop (HIL) simulations using a fixed-wing UAV model and in real flight experiments using quadrotors. It is observed that the algorithm enables a UAV to avoid moving obstacles approaching to it with different directions and speeds.

Description
Selected Poets’ Lived Experience of the Seventh Avenue Streetscape Project: A Phenomenological Study of Meaning and Essence addresses a specific public art project. Public art has a long history of eluding a definition of consensus, and it continues to do so. There is very little in the way of accountability for its effect, and most of what is available is anecdotal. The Seventh Avenue Streetscape (SAS) is no exception in that no follow-ups were ever asked of the community, even though the Melrose Neighborhood District has been revitalized and rescued from its decline with the inception of SAS. It brought residents and business owners together in coordination with the City of Phoenix and Arizona State University to create the unique infrastructure of SAS that presents itself as a sheltered bus stop/outdoor gallery displaying art and poetry on large platform panels to the delight of the citizenry. The purpose of this study was to explore, describe, and interpret the meaning given to the Seventh Avenue Streetscape by poets who participated in that project. The central question guiding the research was “What is the essential meaning and understanding of the lived experience given by poets who participated in the Seventh Avenue Streetscape project and its creation?”
The study was conducted through the qualitative research tradition, guided specifically by the theoretical base known as phenomenology. Phenomenology lends itself particularly well to the study of phenomena such as SAS as its focus is finding the essential in the “everyday” through the expression of lived experience. My primary data source were the poets themselves, those whose poems had been selected to be publicly presented. Once cleared by the Institutional Review Board, my method of data collection involved one-on-one recorded interviews. The interviews were then transcribed and subjected to various methods of data reduction, including coding and themeing the data from the thick description given by the poet-participants. The data revealed patterns among the poets which could be divided into six essential themes, confirming a plausible description and interpretation of SAS. Recommendations included conducting the same study again with the remaining qualifying SAS poets and comparing the results.
