O procedimento crítico adotado organiza uma periodização das obras dos cancionistas particulares, reconhecidos num “contexto de obras” mais geral. A partir disso, empreende-se a compreensão do sentido histórico destas obras frente ao contexto de época. Tendo em vista a definição de tal contexto, recorreu-se à crítica da “noção de MPB” (Música Popular Brasileira), chegando-se à conclusão de que esta noção é uma impostura conceitual. Por isso, fez-se necessária a avaliação de referenciais críticos que tratassem da dinâmica histórica da experiência musical brasileira. Para efeitos de análise, trabalhou-se com a avaliação do projeto musical de Mário de Andrade, reconhecendo a bossa nova como um desdobramento contraditório da “utopia do som nacional” do modernista. Em seguida, a fim de consolidar conceitos e categorias sobre a experiência musical brasileira, levando em consideração o pressuposto da análise histórica materialista calcada nas mediações estéticas, organizou-se a interpretação dos métodos críticos de José Ramos Tinhorão e José Miguel Wisnik. Aí, reconheceu-se não apenas o reforço de certo referencial teóricometodológico, mas a ressonância de problemas cuja cristalização inicial está na própria experiência musical estudada. De posse das categorias críticas anteriormente consolidadas, apresenta-se os primeiros anos das obras de Chico Buarque e Paulinho da Viola como um período de maturação de antinomias estéticas que sedimentam em forma... / This thesis organizes a historical interpretation of the work of two important names of Brazilian musical experience, namely: Chico Buarque de Hollanda and Paulinho da Viola. The critical procedure adopted organizes a periodization of the works of particular musicians, recognized in a more generally context of works. From this, it undertakes to understand the historical meaning of these works in the epochal context. In view of the definition of such a context, one appealed to the criticism of the concept of MPB” (Brazilian Popular Music), coming to the conclusion that this notion is a sham conceptual. Therefore, it was necessary to evaluate the critical benchmarks that treat the historical dynamics of Brazilian music experience. To the analysis, one worked with the evaluation of the musical project of Mario de Andrade, recognizing Bossa Nova as a contradictory split of utopia of national sound of the modernist. Then, in view of consolidating concepts and categories on the Brazilian musical experience, taking into account the assumption of historical materialist analysis based on aesthetic mediation, one organized the interpretation of critical methods of José Ramos Tinhorão and José Miguel Wisnik. In them, it was recognized not only the strengthening of certain theoretical and methodological references, but the resonance of problems whose initial crystallization is in the very musical experience studied. In possession of critical categories previously consolidated, it shows the early works of Chico Buarque and Paulinho da Viola as a maturation period of antinomies aesthetic that sediment objective elements of Brazilian social and political structure in forms of the song language...

This research analyzes the symbolic function and the symbolic games ([1945]) at the thought of Piaget and the improvisational games of Viola Spolin ([1963]). From this perspective, establish dialogues in their entertainment and educational way and shows how the knowledge of these symbolic characteristics and the intuitive knowledge can influence the driving proposals for theater education in public schools with children. This dissertation departs from the meaning established by the relationship between meaning/significant with the intuitive intelligence, which are elements presents in the theatrical play. / O objetivo deste estudo é relacionar os aspectos metodológicos dos jogos teatrais, tais como elaborados por Viola Spolin (1906-1994), e o jogo simbólico (jeu symbolique), como apresentado por Jean Piaget (1896-1980). Esta pesquisa analisa a função simbólica e os jogos simbólicos ([1945]) no pensamento de Piaget e os jogos improvisacionais de Viola Spolin ([1963]). Nessa perspectiva, estabelece diálogos em seus sentidos lúdicos e pedagógicos e apresenta como o conhecimento dessas características simbólicas e do conhecimento intuitivo podem influir na condução de propostas para o ensino do teatro com crianças na escola pública. Este trabalho parte das significações estabelecidas pela relação entre significado/significante e do estabelecimento da inteligência intuitiva, elementos presentes no jogo teatral.

Dubuisson (fl.1666-c.1685) is the sole French viol player-composer between Nicolas Hotman (1613-1663) and Le Sieur de Sainte-Colombe (d.c.1700) whose works are extant. His four suites from a Library of Congress manuscript (1666) are the oldest dated French music for the bass viol; his approximately 125 pieces are contained in five manuscript sources. This thesis brings together, for the first time, all the music from the five sources for study and analysis. Together with the few biographical details, this material is used to assess his position within the French viol school. Brief histories of the viol and the suite in France precede a discussion of Dubuisson's contributions to the evolution of the genre.

This is a compilation of the music performed at the graduation recital of John Estacio on April 11,1991, at 2.30 p.m. in the U.B.C. Recital Hall. There were four pieces performed that afternoon including Azimuth for viola, clarinet and marimba, written in 1989. Ode on the Death of A Favourite Cat, Drowned in a Tub of Goldfishes for S.A.T.B. choir was written in 1989 and uses the text of Thomas Gray. Moments is a set of three pieces for woodwind quintet written in 1990. Viola Concerto is in three movements and was written in 1991 for Reg Quiring, a former U.B.C. student. The concerto is scored for solo viola and chamber orchestra. A cassette copy of the recital is available with this book. / Arts, Faculty of / Music, School of / Graduate

The master thesis presents an overview of face detection task in color, static images. Face detection term is posed in the context of various branches. Main concepts of face detection and also their relationships are described. Individual approaches are divided into groups and then define in turn. In the thesis is in detail described algorithm AdaBoost, which is selected on the basis of its properties. Especially speed of computation and good detection results are key features. In the scope of this work Viola-Jones detector was implemented. This detector was trained with face pictures from public accessible database. Combination of Viola-Jones detector with simple color detector is described. In the thesis is also presented experiment approach to facial features detection.

The purpose of the study was to compare two instructional methodologies designed to improve the intonation accuracy of seventh grade violin and viola instrumentalists. The collection of data was in regard to (1) instructional methodology: aural and aural/visual, (2) performance tasks: A, B, and C; (3) individual pitches (seven from each of the music tasks), and (4) differences between instrument groups: violin and viola. Sixty-eight seventh grade string students from three string classes of two middle schools were randomly assigned to two experimental groups: (a) aural and (b) aural/visual. The instructional period was implemented daily in ten-minute sessions during twenty days by the orchestra instructors of each school. A pretest-posttest format was used to determine if there were any changes in the subjects' intonation accuracy from prior to after the instructional phase was implemented, and if these changes could be attributed to any of the methodologies. The testing material used on both testing sessions included three performance tasks composed of seven notes each. Subjects were recorded on both testing occasions. The data were the scores of absolute pitch deviation, measured in cents from equal temperament, from the pre- and postest; these were treated with analysis of variance. The ANOVA on the posttest scores indicated a non-significant difference between the instructional methodologies in their effectiveness to improve the subjects' ability to play in tune.

The cyclotides are a family of naturally occurring peptides characterized by cyclic cystine knot (CCK) structural motif, which comprises a cyclic head-to-tail backbone featuring six conserved cysteine residues that form three disulfide bonds. This unique structural motif makes cyclotides exceptionally resistant to chemical, thermal and enzymatic degradation. They also exhibit a wide range of biological activities including insecticidal, cytotoxic, anti-HIV and antimicrobial effects. The cyclotides found in plants exhibit considerable sequence and structural diversity, which can be linked to their evolutionary history and that of their host plants. To clarify the evolutionary link between sequence diversity and the distribution of individual cyclotides across the genus Viola, selected known cyclotides were classified using signature sequences within their precursor proteins. By mapping the classified sequences onto the phylogenetic system of Viola, we traced the flow of cyclotide genes over evolutionary history and were able to estimate the prevalence of cyclotides in this genus. In addition, the structural diversity of the cyclotides was related to specific features of the sequences of their precursor proteins, their evolutionary selection and expression levels. A number of studies have suggested that the biological activities of the cyclotides are due to their ability to interact with and disrupt biological membranes. To better explain this behavior, quantitative structure-activity relationship (QSAR) models were developed to link the cyclotides’ biological activities to the membrane-interactive physicochemical properties of their molecular surfaces. Both scalar quantities (such as molecular surface areas) and moments (such as the distributions of specific properties over the molecular surface) were systematically taken into account in the development of these models. This approach allows the physicochemical properties of cyclotides to be geometrically interpreted, facilitating the development of guidelines for drug design using cyclotide scaffolds. Finally, an optimized microwave-assisted Fmoc-SPSS procedure for the total synthesis of cyclotides was developed. Microwave irradiation is used to accelerate and improve all the key steps in cyclotide synthesis, including the assembly of the peptide backbone by Fmoc-SPPS, the cleavage of the protected peptide, and the introduction of a thioester at the C-terminal carboxylic acid to obtain the head-to-tail cyclized cyclotide backbone by native chemical ligation.

This portfolio presents seven compositions composed for different instrumental and vocal forces, accompanied by a commentary and recordings of some of these works. Across the seven pieces there has been a concern with building longer-term structures; establishing a stronger developmental style; and with moving towards a more systematised approach to harmony as a way of creating a harmonic language that can underpin development more efficiently.  Several of the works show a direct engagement with the issue of form, which is approached from the perspective of Classical models, the listener’s perception and in the context of a highly chromatic harmonic language.  In contrast, two works (<i>Aubade</i> and <i>So Turn Your Heart</i>) engage more directly with diatonic models of harmony. The dominant concern across all the works presented has been the desire to create developmental, direct music in which the notion of transformation, rather than stasis and ritual, are of paramount importance.  From a melodic, harmonic and structural point of view each work represents different ways in which this has been attempted. The commentary that accompanies the works explores many of these ideas in more detail as well as setting out the origins and development of each composition. There is also an explanation as to how the initial material was decided upon and utilised during the compositional process. The commentary then concludes with a summary of what has been achieved over the course of the programme and where this might lead in the future.

Ingeniero Civil Eléctrico / La revisión sistemática de la prensa es una importante herramienta para el análisis de presencia de marcas y desarrollo de estrategias publicitarias, el monitoreo de estos medios tradicionalmente es realizado por operadores que manualmente extraen la información. Este trabajo tiene como objetivo presentar un novedoso sistema de detección automática de publicidad sobre imágenes procedentes de diarios y revistas, dentro del marco del proyecto IntelliMEDIA, llevado a cabo por el startup chileno CPDLabs. La metodología para detectar anuncios publicitarios se basa en un modelamiento específico de la estructura de la prensa escrita, permitiendo llegar a obtener una estimación del costo de los anuncios detectados. Para ello se separa el problema en 4 bloques: Preprocesamiento que separa el texto de las imágenes dentro de la página. Detección de logos que busca logos dentro de la página. Detección de publicidad que identifica el anuncio publicitario al que pertenece el logo y finalmente una etapa de tarificación que entrega una estimación del costo asociado al espacio publicitario. El problema es abordado principalmente mediante tres estrategias: Primero la representación de la imagen en descriptores locales, que permite calzar características similares entre imágenes. Segundo, la estrategia de detección de objetos Viola-Jones, algoritmo de machine learning que genera un clasificador en base a un conjunto de imágenes de entrenamiento. La última estrategia es comparar histogramas de color permitiendo integrar información de color a la clasificación. Para medir el desempeño de dichas estrategias se desarrolla un marco de evaluación, que consiste en una base de validación de 20.000 páginas de diario con 27 logos marcados, para así medir el desempeño de las distintas estrategias y configuraciones de parámetros, encontrar una solución eficaz para el problema y analizar las fortalezas y debilidades de los distintos métodos. Los resultados demuestran que la solución es viable y es posible detectar logos mediante descriptores locales y Viola-Jones, logrando desempeños mayores al 90%. Por lo tanto IntelliMediA puede llegar a ser una manera eficaz y eficiente de extraer información publicitaria automáticamente de prensa escrita.
