Song Rhythm Development In Zebra Finches, Julia Hyland Bruno

Dissertations, Theses, and Capstone Projects

This dissertation investigates song-rhythm learning in songbirds. Songbirds have been studied extensively in mechanistic investigations into the sensorimotor underpinnings of the cultural transmission of learned vocalizations. While several studies identified forebrain song-system neurons that generate rhythmic song patterns, we know little about how song rhythms are learned. The first part of the dissertation describes methods for detecting and analyzing birdsong rhythm patterns, and demonstrates their utility for identifying the role of song rhythms in social interactions. Results suggest that rhythm plasticity in zebra finch song may provide a potential vehicle for communication. Controlled song-learning experiments further found that developing zebra …

Writing For Strangers: Structural Transformations Of The Public Letter, 1640-1790, Shang-Yu Sheng

Dissertations, Theses, and Capstone Projects

This dissertation examines public letters in England during the period spanning the English Civil War to the French Revolution, showing how authors employed the printed epistolary form to imagine different relations with the “stranger readers” who constituted the nascent reading public. I employ a formalist approach to analyze the various rhetorics made possible through the public letter’s framed structure, focusing on the assemblages of the narrative positions of letter writer, addressee, and reader. Each chapter describes a mode of the public letter in socio-spatial terms: spectacle, network, community, and public. Building on studies in book history and print culture, this …

Communicationists And Un-Artists: Pedagogical Experiments In California, 1966-1974, Hallie Rose Scott

Dissertations, Theses, and Capstone Projects

A network of experimental workshops, classes, and schools foregrounding interdisciplinary, non-hierarchical, and process-based approaches to teaching and learning emerged in coastal California between 1966 and 1974. These initiatives embodied a new pedagogical approach that I call “communication pedagogy,” in which students were taught to exchange ideas and collaborate, rather than to produce objects. Analyzing three central case studies, Anna and Lawrence Halprin’s Experiments in Environment workshops, Ant Farm’s proposals for learning networks, and Allan Kaprow’s ‘Happenings’ course, I argue that communication pedagogy helped to foster a new paradigm for artistic practice: the artist as facilitator and network-creator. By the mid-1970s …

A Hybrid State/Event Driven Communication-Based Control For Dc Microgrids, Yusef Esa

Dissertations and Theses

The U.S. electric power industry is undergoing unprecedented changes triggered by the growing electricity demand, and the national efforts to reduce greenhouse gas emissions. Moreover, there is a call for increased power grid resiliency, survivability and self-healing capabilities. As a result of these challenges, the smart grid concept emerged. One of the main pillars of the smart grid is microgrids. In this thesis, the technical merits of clustering multiple microgrids during blackouts on the overall stability and supply availability have been investigated.

We propose to use the existing underground distribution grid infrastructure, if applicable, during blackouts to form microgrid clusters. …
