This thesis investigates the feasibility of using a new digital interconnection technology, the IEEE-1394 High Performance Serial Bus, for audio and control data distribution in local and remote music recording studio environments. Current methods for connecting studio devices are described, and the need for a new digital interconnection technology explained. It is shown how this new interconnection technology and developing protocol standards make provision for multi-channel audio and control data distribution, routing, copyright protection, and device synchronisation. Feasibility is demonstrated by the implementation of a custom hardware and software solution. Remote music studio connectivity is considered, and the emerging standards and technologies for connecting future music studio utilising this new technology are discussed. / Microsoft Word / Adobe Acrobat 9.46 Paper Capture Plug-in

Para tanto, desenvolvemos uma pesquisa qualitativa a partir do uso das diretrizes investigativas da etnometodologia (GARFINKEL, 1967; COULON, 1995a), pelo fato de caracterizar-se pelo estudo de atividades cotidianas dos indiv?duos, com aten??o ao modo como eles tomam decis?es, comunicam, resolvem problemas, raciocinam, seja por a??es corriqueiras seja por eruditas, por meio de tecnologias e m?dias; bem como pela pesquisa-a??o (THIOLLENT, 2003), no que se refere ? interven??o pedag?gica proposta por n?s. Assim, a pesquisa ? apresentada em duas etapas, a saber: 1) o uso das tecnologias e m?dias no processo de ensino-aprendizagem, investigando alunos e professores; 2) a aprendizagem transm?dia na sala de aula, uma interven??o pedag?gica na escola-campo de pesquisa. Os dados foram analisados por unidades relacionais, considerando o tema central: uso de tecnologias e m?dias. Como resultado, constatamos que: o livro did?tico ainda ? o principal suporte utilizado pelo professor; as tecnologias e m?dias digitais apenas s?o mencionadas pelos alunos quando estes realizam atividades de cunho acad?mico por iniciativa pr?pria; o letramento midi?tico do professor interfere na abordagem de privilegiar e mediar o letramento midi?tico dos alunos. Assim, conclu?mos que a aprendizagem transm?dia modificou a din?mica de ensino-aprendizagem, propiciando maior entusiasmo e intera??o dos alunos com/sobre o objeto de conhecimento, estabeleceu um di?logo significativo entre professoraluno e aluno-aluno, al?m de ter potencialidade de letramento midi?tico. / The thesis Transmedia Learning in the Classroom: the potential of media literacy aimed to investigate transmedia learning as a pedagogical approach of media literacy with teachers and students of the final grade in public basic education. For this, we developed a qualitative research using the investigative guidelines of ethnomethodology (GARFINKEL, 1967; COULON, 1995a ), by the fact it is characterized in individuals daily activities study, with attention to how they make decisions, communicate, solve problems, reason, whether by ordinary or erudite shares through technologies and media, as well as we use the action research guidelines (THIOLLENT, 2003), in regard to educational intervention proposed by us. Thus, our research is presented in two stages, namely: 1) the use of technology and media in the teaching and learning process, investigating students and teachers; 2) the transmedia learning in the classroom, an educational intervention in school where we developed this research. The data collected were analyzed in relational units considering a central theme: the use of technology and media. As a result we found that textbook is still the main media used by teacher; technologies and digital media are only mentioned by students when they carry out educational activities on their own initiative; teachers? media literacy interfere in their approach to conduct, prioritize and mediate the students media literacy process. Thus, we conclude that transmedia learning changed the dynamics of teaching and learning in classroom, providing greater enthusiasm and interaction of students with / about the object of knowledge, established a meaningful dialogue between teacher-student and studentstudent, as well as transmedia learning has potential of literacy media.

O projeto Um País, Um Violão , realizado no Centro de Informática da Universidade Federal de Pernambuco, se propõe a estudar a interpretação violonística no acompanhamento da bossa nova e, neste contexto, o reconhecimento de acordes tem papel fundamental. Dado que a bossa nova possui harmonia jazzística, favorecendo a utilização recorrente de dissonâncias, e os intérpretes freqüentemente realizam re-harmonizações durante a execução das peças, a maneira com a qual tais aspectos são executados torna-se uma informação importante na caracterização de um dado intérprete e no estudo de sua interpretação. Entretanto, para realização de tal estudo, os requisitos do reconhecimento de acordes são mais exigentes do que os considerados na literatura atual. O processo proposto lida com harmonia jazzística, a mais complexa estrutura harmônica na música ocidental. Nenhum trabalho encontrado na literatura considera tal complexidade. Infelizmente, a tecnologia atual de captura MIDI em violões é muito sensível a diversos fatores, e ainda insere uma quantidade grande de ruído nos dados capturados. Portanto, o processo inclui uma etapa de préprocessamento das seqüências capturadas para minimização de ruídos. Além disso, por motivos que serão discutidos no quinto capítulo, realizou-se um estudo para garantir que os atrasos gerados pelo captador MIDI são aceitáveis. Para minimizar os ruídos inerentes à captura realizada pelos violões MIDI, foi proposta uma técnica baseada em duas bases de regras, executadas em série, porém realizando-se uma segmentação simples antes da execução da segunda base. A primeira base contém regras simples e elimina eventos claramente ruidosos, além de marcar potenciais ruídos para análise na segunda etapa quando mais informações estão disponíveis. A segunda base contém regras mais complexas, que consideram informações harmônicas e contextuais locais para tratar eventos marcados na primeira fase, eliminando ou corrigindo o ruído restante. O processo proposto para detecção de acordes nas seqüências MIDI divide o problema em três fases: primeiramente, realiza-se a segmentação da seqüência, tentando identificar os pontos de mudança de acorde através de um algoritmo que utiliza conhecimento específico do domínio. Em seguida, utiliza-se uma função de utilidade e um conjunto de padrões de acordes recorrentes em harmonia jazzística e posições comuns no braço do violão para identificar os acordes candidatos em cada segmento, construindo-se um grafo. Por fim, particiona-se o grafo encontrado em regiões de incerteza, ou seja, regiões onde há mais de um acorde candidato para cada camada, cercadas por regiões de certeza, e utiliza-se um conjunto de regras contendo padrões de seqüências recorrentes em harmonia jazzística para tentar resolver os casos ambíguos em cada sub-grafo. Além disso, realizou-se um estudo, inédito na literatura, sobre a confiabilidade da precisão temporal da captura realizada por violões MIDI, comparando-a com a precisão obtida pelos algoritmos de detecção de ataques em sinais de áudio. O pré-processamento obteve bons resultados na minimização de eventos ruidosos nas seqüências MIDI. Os resultados chegaram a 74,44% de precisão em reconhecimento de acordes, e foram bastante satisfatórios, especialmente com respeito à completude harmônica envolvida quando considera-se a quantidade de dissonâncias usadas na harmonia jazzística

MIMICS is an acronym for Multitouch Interface as a MIDI Control Suite. Multitouch interfaces are well known for their softer learning curve compared with classical computer graphic interfaces. Therefore, its application in music interfaces may solve some of the actual limitations of hardwarebased and software-based devices. The multitouch solution is based on an optical effect called Frustrated Total Internal Reflection which is forced by using infrared light sources. This effect allows finger tracking using computer vision engines. In the thesis we describe a low-cost and affordable Hardware/Software solution for MIDI-based devices control from a functional multitouch environment. The MIMICS is presented to the user as a rear projected 30 inches screen containing a graphical interface adapted for multitouch. Implementation of several ‘ready-to-play’ applications is demonstrated that emulate classical and new MIDI control devices. The report also contains an evaluation of the results demonstrating that MIMICS is suitable for life-oriented music performances as well as for recording studio works.

Cette thèse porte sur l'étude de la transition d'après-midi (TA) de la couche limite atmosphérique (CLA). La TA est une période complexe du cycle diurne, de par son manque de stationnarité et parce qu'elle est régie par un ensemble de forçages qui faiblissent et dont les rôles respectifs changent par rapport à ce qu'ils ont pu être durant la période convective. Il résulte une moins bonne compréhension de cette période que des régimes quasi-stationnaires convectifs, neutres ou stables. La TA pourrait conditionner l'établissement du brouillard nocturne, influencer le développement de la couche limite du lendemain et être une phase clé du cycle diurne pour la ventilation des espèces en trace vers l'atmosphère libre. Par conséquent, de meilleures description et compréhension de la TA pourraient améliorer les modèles météorologiques et de qualité de l'air. Les principaux objectifs de la thèse ont été de mieux comprendre comment la turbulence décroît pendant la TA en mettant l'accent sur l'évolution de la structure verticale de la turbulence lorsque les transferts d'énergie en surface diminuent progressivement, et sur le rôle que joue la surface à ce moment particulier du cycle diurne. Le projet international BLLAST (Boundary Layer Late Afternoon and Sunset Turbulence) a servi de cadre à cette thèse. La campagne de mesures qui s'est déroulée en été 2011 sur le Plateau de Lannemezan, au nord de la chaîne Pyrénéenne, a fourni les nombreuses observations utilisées dans cette thèse. Une approche complémentaire aux observations est l'utilisation d'un modèle atmosphérique permettant de résoudre explicitement les échelles de la turbulence (LES). / This thesis focuses on the afternoon transition (AT) of the atmospheric boundary layer (ABL). This transitional period is complex, because it is non-stationary and most of the forcings, though smaller than during the previous convective period, may come into play. Thus, this transitional period is less understood than the quasi-stationary convective, neutral or stable regimes. Yet, the AT could impact on the nocturnal fog set up, influence the boundary-layer development on the following day and play a crucial role in the transport and dispersion of pollutants and trace species towards the free troposphere. Therefore, a better understanding of the AT could improve the meteorological models. One of the main objectives of the thesis is to improve the knowledge of the decay of turbulence during the AT, when the surface energy transfers are gradually decreasing. We especially put emphasis on the evolution of the ABL turbulence vertical structure. This work is in the core of the BLLAST (Boundary Layer Late Afternoon and Sunset Turbulence) international project. A field campaign took place in summer 2011 in France, on the northern side of the Pyrenean foothills (at "Plateau de Lannemezan"), providing numerous observations used in the thesis. In addition, we also used a Large-Eddy Simulation (LES) with which the turbulent scales can be explicitly resolved. Thanks to this approach, the evolution during the AT of the scale definitions, scaling laws, turbulence characteristics and of the role of the boundary layer processes are now better understood. Thanks to the set of observations, an overview of the BLLAST ATs has been done, according to the various meteorological conditions as well as the structure and evolution of the mean and turbulence structure of the ABLs. A large variability of the AT duration was observed, depending on the surface characteristics and atmospheric conditions. The evolution of the turbulent characteristics during the AT has been studied at the surface and higher in the ABL by means of aircraft measurements and LES data. The study points out the LES ability to reproduce the turbulence evolution throughout the afternoon.

Les micro-usures dentaires sont un outil permettant la reconstitution des régimes alimentaires de nombreuses espèces, notamment les herbivores. L'efficacité de cette méthode a été prouvée dans le cas d'espèces sauvages, mais peu d'études ont été effectuées sur des populations domestiques. L'interprétation des résultats repose sur des référentiels qui n'existent pas en contexte domestique, où l'alimentation des troupeaux est influencée par l'éleveur. La création de ce référentiel est nécessaire pour interpréter les résultats d'espèces domestiques, et notamment en archéologie pour étudier les modes de gestion des troupeaux d'espèces herbivores de la triade domestique (bovin, ovin et caprin). Sa création est l'objectif de cette étude, avant son application à des ensembles archéologiques de trois sites du sud de la France, Lattara, le Castellas et les Terriers. Le référentiel a mis en évidence une influence climatique forte à l'échelle du continent européen, tandis qu'à l'échelle du site des facteurs anthropiques ou saisonniers sont observés. L'étude des restes des sites archéologiques montre des modes d'élevage extensifs, avec des zones d'alimentation distinctes entre les troupeaux de caprinés et de bovins. Une évolution dans l'alimentation des bovins s'observe au troisième siècle avant notre ère à Lattara uniquement, liée à une probable réorganisation économique et donc agropastorale, en relation avec une forte augmentation démographique. Un élevage à deux échelles, familiale et tournée vers le commerce est envisagé à partir de cette période. Enfin certains assemblages semblent indiquer des abattages sur des intervalles temporels réduits. / Dental micro-wear is a tool for the reconstruction of diets of many species, including herbivores. The effectiveness of this method has been proven for many wild species, but few studies have been conducted on domestic populations. Interpretation of results for wild species is based on database that do not exist in domestic context, where feeding of herds is influenced by the herder. Creation of this database is necessary to interpret results of domestic species, especially in archaeology to study the management of herds of herbivorous species of the domestic triad (cattle, sheep and goat). Its creation is the main object of this study, before its application to teeth remains of three archaeological sites from southern France, Lattara, le Castellas and les Terriers. The database has highlighted a strong climatic influence at the European scale, while at the level of the site other factors including anthropogenic choices or seasonality are observed. The study of archaeological samples from the sites revealed extensive management with feeding areas separated from the herds of cattle and caprine. An evolution in alimentation of cattle is seen in the third century BCE in Lattara only, probably related to an economic reorganization and so agropastoral, in connection with a strong demographic growth. A two-scales breeding, family and trade oriented is thought for this period. Finally, some data sets suggest slaughters in reduced temporal intervals.

This thesis is focused on the question whether it is possible to fully simulate the sound of real musical instruments on the personal computer. The opening chapters deal with basic characteristics of sound information, its perceiving and also its digital form. Futher there is an elaborate analysis of computer simulation in comparison with legitimate records. The output of this part are worded assumptions. The next parts offer a detailed look at programming approaches and methods of computer sound creation. The research leads to a hearing test in which author tries to confirm the hypotheses as well as to answer the primary question.
