Research regarding liveness and embodiment in electronic music has tended to explore the relationship of bodies and instruments, audience perception, interfaces, and shifting definitions, less theoretical and empirical study has considered network situations, perhaps given their relative cultural novelty. Network music has seen many advances since the time of the Telharmonium, including the invention of the personal computer and the widespread proliferation of internet connectivity. These advances have fostered a unique approach to live electronic music that facilitates collaboration in a field where solo performance is perhaps more common. This thesis explores the design of network music interfaces, and how those interfaces mediate collaborations. Three new network music system interfaces, each using different a different paradigm for interface design are presented in this study. One an instrument for creating modular feedback lattices. Another is a three dimensional virtual pattern sequencer. And the last is a web based collaborative live coding language. Accompanying each system is an evaluation using quantitative and qualitative analysis to frame these instruments in a larger context regarding network music. The results highlight important themes concerning the design of networked interfaces, and the attitudes of musicians regarding networked collaborations.

Filmes de ligas FePt com uma estrutura quimicamente ordenada Tetragonal de Face Centrada FCT (tipo L1 IND.0) e textura [001] apresentam anisotropia magnética perpendicular, alta coercividade e grande efeito Kerr polar magnetoóptico. Entretanto, filmes completamente ordenados são normalmente obtidos através de um processo de \"sputtering\" com deposições em altas temperaturas do substrato(T IND. S > OU =600 ºC) ou por pós-tratamento térmico em temperaturas maiores que 500 ºC. As pesquisas atualmente em desenvolvimento visam a obtenção dessa estrutura ordenada a temperaturas mais baixas, o que seria mais adequado para aplicações práticas dos filmes. Neste trabalho, procuramos as melhores condições para a preparação de filmes de FePt com a fase ordenada FCT(001) em reduzidas temperaturas. Investigamos a influência do método de deposição, temperatura do substrato, espessura do filme e tipo de substrato sobre o grau de ordem química e textura dos filmes de FePt e, consequentemente, sobre suas propriedades magnéticas. Os filmes finos de ligas Fe IND.xPt IND. x-1(com x = 50 at%) foram preparados por \"Sputtering Magnetron DC\", através de dois diferentes métodos de deposição: pelo usual de codeposição e pelo método de deposiçãO alternada monocamadas atômicas (DAM). Os filmes foram crescidos sobre substratos de SiO IND.2/ Si(100), Si(100) e MgO(100), com e sem uma camada \"buffer\" de Pt ( com espessuras de 50 1 766 nm), sob T IND. s variando de temperatura ambiente a 600 ºC. O \"buffer\" de Pt foi usado para permitir melhores condições para a indução de um crescimento \"epitaxial\" da ordenada fase FCT(001) nos filmes de FePt. Os resultados da caracterização estrutural e magnética realizados através das técnicas de Difração de RAios-X (XRD) e Magnetometria de Amostra Vibrante (VSM) mostram que os substratos de MgO São adequados para induzir um crescimento \"epitaxial\" de filmes de FePt ) com uma estrutura FCT e textura [001]. Entretanto, com o uso de um \"buffer\" de Pt otimizado (com predominante fase FCC(100)), pré-depositado sobre MgO, foram obtifos melhores resultados em termos de \"epitaxia\" conveniente para o ordenamento da estrutura cristalina, para os filmes de FePt preparados por ambos os métodos de deposição. Os resultados mostram também que o efeito de um crescimento \"epitaxial\" induzido varia com a espessura do filme. Em relação ao método de deposição, os resultados revelam a maior eficiência de método DAM em comparação com o métodos de codeposição para a preparação de filmes de FePt com a fase FCT(001), em temperaturas reduzidas (T IND.s < OU = 400ºC). Com o uso do método DAM, foi possível a obtenção da fase ordenanda FCT(001) em filmes de FePt crescidos diretamente sobre o MgO em T IND. s = 400ºC. Para filmes de FePt crescidos sobre Pt/MgO, a formação da fase FCT(001) foi verificada em T IND.s = 200ºC e um alto grau de ordenamento químico (S = 0,88) em T IND. s = 400ºC. Estudos de Espectroscopia de Absorção de Rios-X (XAS) também foram realizados. / FePt alloy films, with a chemically ordered face-centered-tetragonal FCT (type LI IND.0) structure and [001] texture, present perpendicular magnetic anisotropy, high coactivity and large polar magneto-optical Kerr effect. However, completely ordered films are usually obtained either by sputtering process at high substrate temperatures (T IND.s MAIOR IGUAL A 600°C) or by postanneling treatment at temperatures higher than 500°C. For technological purposes the preparation temperatures has to be as low as possible. In this work we have searched the more adequate conditions to preparation of FePt films with ordered FCT(001) phase at reduced temperatures. We have investigated the influence of deposition methods, substrate temperature, thickness of film, and type of substrate on the degree of the chemical ordering and preferred texture of FePt films and, consequently, on their magnetic properties. The Fe IND.xPt IND.1-x alloy thin films (with x SEMELHANTE A 50 at%) were prepared by DC Magnetron Sputtering, via two different deposition methods: a conventional code position method and an alternate monatomic layer (DAM) deposition method. The films were grown on SiO IND.2/Si (100), Si (100) and MgO (100) substrates, with and without a Pt buffer layer (thickness ranging from 50 to 76 nm), at T IND.s varying from room temperature to 600°C. The Pt buffer layer was used for obtaining better conditions to the induction of an epitaxial grown of FePt films with the ordered FCT(001) phase. The results of structural and magnetic characterization performed by X-ray diffraction (XRD) and vibrating sample magnetometry (VSM) show that the MgO substrates are adequate to induce an epitaxial growth of FePt films with a FCT structure and [001] texture. However, with the use of an optimized Pt FCC(100) buffer layer pre-deposited on MgO, the best conditions to an epitaxial induced growth were obtained, by both deposition methods. The results show also that the quality of the epitaxial induced growth depends on the thickness of the film. In relation to the deposition method in comparison to the code position method for preparation of FePt FCT(001) films, at reduced temperatures (T IND.s MENOR IGUAL A 400°C). With the use of the DAM method it was possible to obtain the ordered FCT(001) phase in the FePt film grown directly on MgO, at T IND.s = 400°C. For FePt film grown on Pt/MgO, the formation of the FCT(001) phase was verified at T IND.s = 200°C, and high degree of chemical order (S=0,88) was obtained at T IND.s = 400°C. X-ray Absorption Spectroscopy (XAS) studies also were done.

abstract: This document accompanies new recordings of four recent sonatas for trumpet and piano. The project’s objective is to promote these works, while providing a comprehensive resource for potential performers. The four sonatas were selected based on their appeal to modern audiences. Composers Brendan Collins, Luis Engelke, William Rowson, and Christoph Nils Thompson each represents a different country, and they offer significant contributions to the trumpet repertoire. Each sonata expertly features the trumpet by highlighting its lyricism, virtuosity, and ability to cross genres. The accompanying document draws upon interviews with the four composers, which reveal insights into the compositional process and provide details that performers will find useful. This document also offers in-depth musical descriptions, allowing performers to enhance their understanding of each sonata. The principal component of the document is the performer’s guide: Advice is presented directly to the trumpet player that has been garnered from the composers’ interviews, study of the music, and the author’s thoughts on preparing the music. To help other young musicians better comprehend the recording process, the author’s own experience is detailed. Ultimately, this document provides a window into the lifespan of the four sonatas; from their initial composition through the various stages of studying and rehearsing, culminating with the experience of recording these works for the first time. / Dissertation/Thesis / Doctoral Dissertation Music 2019

With the quick abandonment of VCR technology and the adoption of digital and online replacements, people give up freedom and personal power in the name of perceived convenience. VCRs and VHS tapes served two needs: the need to time-shift programming and the need to archive The internet and DVR technology fulfill the first need, that of time-shifting, but completely ignore the need of people to archive, which is a need many people don't even realize they have until they are no longer able to archive programs in both an audio/visual and physical manner. The disappearance of physical recording also makes it impossible for others to use ones VHS tapes for anthropological investigation. DVR records do not end up in thrift stores, or flea markets, and are not easily bequeathed after a person passes. By investigating one man's VHS collection, encouraging others to use tapes, and using tapes as a raw material with which to create new work, I hope to inspire others to realize what they have lost, or perhaps, given up.

Microstructural and electrophysiological properties of neural tissue are substantially influenced by the immediate extracellular environment wtihin the nervous system. These properties are also arguably the most clinically-relevant and sensitive measures of nerve health. However, the neurological architecture, physiology, and surrounding extracellular matrix are hard to mimic in vitro, and an increasing need for culture platforms that reproduce these complex features has led to the development of 3D cultures and microscale engineered tissues for functional assays. Using a dual hydrogel construct and explants from rat embryonic dorsal root ganglia, we present an in vitro platform for culturing spatially-controlled 3D neurite growth that supports both intracellular and extracellular electrophysiological recordings. Specifically, these 3D neural cultures in hydrogel exhibit both structural and functional characteristics that closely mimic those of sensory peripheral nervous tissue found in vivo. However, the 3D hydrogel constructs allow incorporation of other cell types, fabrication in any geometry, and simultaneous electrical stimulation and probing, providing a viable assay for systematic culture, manipulation, and testing of biomimetic neural growth in any mechanistic study necessitating physiologically-relevant readouts. / acase@tulane.edu
