The area of computer vision has been making big improvements in the latest decades, equally so has the area of electronics and small computers improved. These areas together have made it more available to build small, standalone systems for object detection in live video. This project's main objective is to examine whether a small device, e.g. Raspberry Pi 3, can manage an implementation of an object detection algorithm, called Viola-Jones, to count the occupancy of sitting people in a room with a camera. This study is done by creating an application with the library OpenCV, together with the language C+ +, and then test if the application can run on the small device. Whether or not the application will detect people depends on the models used, therefore three are tested: Haar Face, Haar Upper body and Haar Upper body MCS. The library's object detection function takes some parameters that works like settings for the detection algorithm. With that, the parameters needs to be tailored for each model and use case, for an optimal performance. A function was created to find the accuracy of different parameters by brute-force. The test showed that the Haar Face model was the most accurate. All the models, with their most optimal parameters, are then speed-tested with a FPS test on the raspberry pi. The result shows whether or not the raspberry pi can manage the application with the models. All models could be run and the Haar face model was fastest. As the system uses cameras, some ethical aspects are discussed about what people might think of top-corner cameras.

A Sonata é composta por seis movimentos: Hora Lunga , Loop, Facsar, Prestissimo con sordino, Lamento e Chaccone chromatique. A obra destaca e valoriza a sonoridade da viola explorando todos os registros e muitas das possibilidades técnicas do instrumento. Com o objetivo de alcançar uma interpretação embasada no estilo do compositor, iniciamos a pesquisa com uma breve biografia, buscando informações que aproximem o intérprete de sua obra e seu pensamento musical. A seguir, o segundo capítulo contextualiza teoricamente cada movimento da sonata, preparando o caminho para as decisões adotadas na prática, descritas no terceiro capítulo, que tem o objetivo de auxiliar na resolução das demandas técnicas e interpretativas da obra. / Abstract: The Sonata for solo viola (1991-1994) by György Ligeti features the musical processes created by the composer in the period between 1950 and 1994. The work consists of six movements: Hora Lunga, Loop, Facsar, Prestissimo con sordino, Lamento and Chaccone chromatique. The piece features and values the sonority of the viola, by exploring its whole range and many of its technical possibilities. In order to achieve a performance based on the composer's style we begin this study with a short biography, highlighting information which will help the performer understand the composer's musical thinking and works. The second chapter outlines theoretically each movement of the sonata, paving the way for the subsequent technical strategies put into practice, and described in the third chapter, which has the purpose of helping to solve the work's technical and interpretative demands. / Mestrado / Praticas Interpretativas / Mestre em Música

Because I have not yet found specific material for improvisation in this instrument, I have raised questions about the existence and form of this practice. My hypothesis is that, with a method suitable to the instrument and its particularities, which includes the study of scales and arpeggios, the student shortens the way in the realization of different pieces, facilitates the immediate transposition of songs to other tones and fosters basic knowledge to improvise . The objective of this work is to investigate the processes of improvisation for viola, starting from scales, arpeggios and rhythmic / melodic models. The methodology used was to listen and to transcribe elements of the common practice of diverse violeiros and to extract the basic technique for its construction. I started with authors who deal with improvisation in a general way (BENSON, 2003), idiomatics (ALVIN and ASSIS, 2000), and authors dealing specifically with the instrument and the like (VILELA, 2013) . The results were the confirmation of the hypothesis raised and the construction of didactic material for brazilian ten strings guitar with cebolão tuning, besides the evidence that improvisation in the traditional context not only exists, but also in a particular way, more associated with prosody Rhythm, and that the choice of tonality, within the described tuning influences directly in its practice. / Esse trabalho diz respeito a improvisação na viola caipira com afinação cebolão, utilizando como estudo de caso e aplicação o cateretê Vide Vida Marvada, de Rolando Boldrin. Por não ter encontrado até a presente data, material específico para improvisação na viola, levantei questões sobre a existência e a forma dessa prática. Minha hipótese é de que, com um método adequado ao instrumento e suas particularidades, que abarque o estudo de escalas e arpejos, o estudante encurta caminho na realização de peças diversas, facilita a transposição imediata de músicas para outros tons e fomenta conhecimento básico para improvisar. O objetivo deste trabalho é investigação dos processos de improvisação para viola, partindo de escalas, arpejos e modelos rítmico/melódicos. A metodologia utilizada foi de ouvir e transcrever elementos da prática comum de violeiros diversos e extrair a técnica básica para a sua construção. Embasei-me em autores que dizem respeito a improvisação de uma maneira geral (BENSON, 2003), idiomatismo (ALVIN e ASSIS, 2000), e autores que tratam especificamente do instrumento viola e afins (VILELA, 2013), (CORRÊA, 2000). Os resultados foram a confirmação da hipótese levantada e a construção de material didático para viola com afinação cebolão, além da evidenciação de que a improvisação no contexto violeiro tradicional não só existe, como é recorrente, entretanto de uma maneira particular, mais associada a prosódia ao ritmo, e que a escolha da tonalidade, dentro da afinação descrita influencia diretamente na sua prática.

Une interaction mutualiste peut être définie comme un échange de services, qu’ils soient trophiques ou non, entre individus d’espèces différentes. La myrmécochorie est un mutualisme dans lequel les fourmis récoltent des graines portant un appendice charnu appelé élaïosome (le tout formant une diaspore), les ramènent jusqu’au nid où l’élaïosome est détaché et consommé. La graine, restée intacte, est alors rejetée du nid où elle pourra rester ou être re-dispersée par un autre vecteur avant de germer. Dans ce contexte, le comportement de récolte des fourmis envers les diaspores est décisif pour leur dispersion. Divers traits tels que la morphologie, la composition chimique et la phénologie des graines myrmécochores influencent l’efficacité de leur dispersion par les fourmis. Néanmoins, la disponibilité spatio-temporelle de ces graines est un trait dont l’influence sur le comportement des fourmis reste peu connue.Dans cette thèse, nous nous sommes intéressés à l’influence de la disponibilité spatiale − en termes d’abondance − des diaspores de Chelidonium majus sur leur récolte et leur dispersion par les fourmis Myrmica rubra. Alors que les ouvrières exploitent la totalité d’un petit agrégat de diaspores, seule la moitié d’un large agrégat est exploité. Ceci suggère que la myrmécochorie stricte est efficace pour des plantes produisant peu de graines tandis qu’une libération massive de diaspores nécessite des modes de dispersion complémentaires. Concernant la disponibilité temporelle, des expositions successives à une même espèce de graines (V. odorata ou C. majus) conduisent à une diminution de l’intensité de leur récolte voire à une complète extinction de ce processus dans le cas de V. odorata. En effet, face à ces dernières, l’extinction de la réponse des fourmis persiste pendant au moins deux mois. Elle apparait également plus rapidement que pour les graines de C. majus et concerne toutes les étapes du processus de myrmécochorie puisque un ratio croissant de graines de V. odorata sont rejetées encore pourvues de leur élaiosome. Cette différence dans le comportement de récolte et dans son évolution temporelle ne semble pas liée à un bénéfice différentiel retiré de la consommation des élaïosomes provenant de ces deux espèces de graines myrmécochores. Par ailleurs, les larves semblent jouer un rôle de régulateurs de la récolte des diaspores de V. odorata et donc dans le phénomène d’extinction. L’ensemble des résultats présentés dans cette thèse met en évidence le caractère dynamique de cette interaction plante-fourmis, dont l’issue et la stabilité varie selon l’espèce considérée et la disponibilité spatio-temporelle des diaspores. / Doctorat en Sciences / info:eu-repo/semantics/nonPublished

Musical analysis has traditionally been located within the context of musicology. It is therefore an activity usually considered the purview of music scholars rather than practical musicians. The musical analyses produced by music scholars therefore provide us with intellectual understandings of musical works, rather than insights into the experience of listening to or playing music. In this thesis, I will propose that those agents involved in practical music-making can produce insights into musical works that are as valid as the work of traditional music scholarship. I will attempt to re-conceptualize the position of the ‘knower’ or ‘experiencer’ - the performer - of music as one with primary access to knowledge of a musical work, and therefore ideally suited to offer analyses of these works. The establishment of the performer as a bearer of central analytical knowledge functions in direct opposition to the traditional distinction between ‘theory’ and ‘practice’. My thesis will trace the Platonic origins of the philosophical separation of practice and research, and as an alternative to the traditional separation of practice and research, I shall explore the concept of Practice-Based Research (PBR). My exploration of PBR will be informed by phenomenological approaches to music scholarship. As a field of enquiry which concerns itself with experience, the phenomenology of music suggests that the mind and body of the practitioner are important sources of musical insight. To address this issue, Bourdieu’s notion of habitus will be explored. The habitus will be shown to contain a vast network of socio-cultural codes informing the practitioner’s relationship with the musical work. A central aim of this thesis is to explore the possibilities of using practice-based research as the foundation for the study and analysis of a composition, in order to allow for a deeper understanding of the work by means of the generation and harnessing of practical knowledge. Thus, the theoretical outline of PBR provided in this thesis will be applied to a piece of practical performance-based analysis. As such, an analysis of Mahler’s Quartetsatz will be used as the basis on which to draw knowledge in this project.

Research on the origins of the violoncello reveals considerable dispute concerning the existence and identity of its ancestor, the bass violin. This study focuses on the classification of the sixteenth- and early seventeenth-century bass violin by means of the following criteria: construction, early history and development, role due the social status of builders and players, use within the violin band, performing positions, and defining terminology. Accounts of inventories, organological treatises, music theoretical writings, lists of households and royal courts, descriptions of feasts, reports of choreographies and iconographical examples confirm the bass violin's presence in the late sixteenth century and beyond. Three of the earliest unchanged extant organological examples embody, complement and corroborate the bass violin's identification, and conclude the essay.

Efter att vid två olika tillfällen spelat på masterclasses för violinprofessor Ulf Wallin, rekommenderades jag ett huvudinstrumentbyte från violin till viola. Detta med tanke på de rygg- och nackproblem som jag brottats med under en längre period och som hindrat mig från att komma vidare i mitt violinspel. I detta arbete utforskar jag speltekniska skillnader mellan violin och viola. Jag har under åtta veckor systematiskt övat på skalor, etyder och repertoar. Jag har valt att dela upp processen i fyra olika moment: instrumentfattning, stråkteknik, intonation och altklav. Under processen redogör jag för hur jag arbetat med de olika momenten och med hjälp av mina lärare tagit mig an de utmaningar jag stött på. Jag har regelbundet fört loggbok och antecknat intressanta saker jag upptäckt under övningspassen. Jag har också spelat in videoklipp för att kunna följa min utveckling. Jag har analyserat denna process utifrån Gibsons affordance-begrepp, vilket har fått mig att inse varför jag har olika förutsättningar beroende på om jag spelar violin eller viola. Arbetet har resulterat i att jag uppnått en förbättrad teknik och musikaliskt uttryck. Jag redovisar det genom en inspelning jag gjort av ett solostycke med ljud och bild i en gotländsk kyrka.
