Full textEsta dissertação pretende projectar A Presença da Flauta Traversa em Portugal de 1750 a 1850. Tendo como um dos principais objectivos reunir, pela primeira vez, num só documento, o maior número possível de instrumentos dos construtores nacionais, foram localizadas um total de dezoito flautas traversas e um flautim. Deste instrumentário, quinze são provenientes da família Haupt, três da família Silva e um do construtor Xavier Paranho. O primeiro capítulo incide na abordagem historiográfica do instrumento, no segundo capítulo efectua-se o estudo organológico das flautas traversas nacionais, o terceiro capítulo é dedicado às fichas de identificação técnica de cada instrumento e, por último, a inserção da flauta traversa no repertório e no ensino, em Portugal, é tratada no capítulo quatro. A abordagem das obras setecentistas de António Rodil (c.1710-1788), Pedro António Avondano (1714- 1788) e Fr. Manuel dos Santos Elias (c.1740-c.1780), e o repertório oitocentista de João D. Bomtempo (1775-1842), José Maria da Silva (1789-?), José Maria Ribas (1796-1861), António José Croner (1826-1888), José Francisco Arroio (1818-1868) e João Parado (?-1842), assim como, o método para flauta coordenado por Cézar Augusto P. das Neves (1841-1920), encerram este projecto.
This dissertation intends to project the presence of the transverse flute in Portugal from 1750 to 1850. One of its main aims is to bring together for the first time, in one document, the largest possible number of instruments by national builders. In the wake of this research, eighteen transverse flutes and one piccolo flute have been located. Within this set of instruments, fifteen were built by the Haupt family, three from the Silva family, and one from Xavier Paranho. The dissertation’s first chapter offers a historiographic overview of the transverse flute. In the second chapter an organologic study of the national transverse flutes is laid out. The third chapter addresses the specifications of each instrument, while the final chapter deals with the presence of the flute in Portuguese musical literature and teaching repertoire. An overview of 17th century compositions of António Rodil (c. 1710-1788), Pedro António Avondano (1714-1788), and Fr. Manuel dos Santos Elias (c. 1740-1780); the 18th century repertoire of Joâo D. Bomtempo (1775-1842), José Maria da Silva (1789-?), José Maria Rivas (1796-1861), António José Croner (1826-1888), José Francisco Arroio (1818-1868) and João Parado (?-1842); and the flute method conceived by Cézar Augusto P. das Neves (1841-1920) conclude this dissertation.

Full textPropomos nesta tese um método para estudar deformações de curvas planas que leva em consideração a geometria delas, bem como as suas singularidades. Consideramos em detalhes os fenômenos locais que ocorrem genericamente em famílias de curvas com dois parâmetros. Obtemos informações sobre as inflexões e vértices que aparecem nas curvas deformadas. Obtemos também as configurações das evolutas das curvas e das suas deformações e aplicamos os nossos resultados nas projeções ortogonais de curvas espaciais. Finalmente, consideramos o perfil de uma superfície regular no espaço Euclidiano R3. O perfil é a imagem do conjunto singular de uma projeção ortogonal da superfície, esta é uma curva plana e pode ter singularidades. Estudamos as alterações na geometria do perfil quando a direção de projeção muda localmente na esfera unitária.

Full textWe study and compute wave invariants of Schrödinger operators acting on sections of Hermitian line bundles over even-dimensional flat tori. The Schrödinger operators are constructed from translation-invariant connections on the bundle and a potential, a smooth function on the torus. Restricting to bundles with nondegenerate Chern class we study the extent to which the spectrum of the Schrödinger operator of a given potential determines the connection. The first five wave invariants are computed explicitly using the computer algebra software Mathematica. For simple potentials we find a full characterization of the isospectrality of the translation-invariant connections. We also prove general properties of the wave invariants, which imply a more general existence of nonisospectral connections but which also show limitations of the spectral information contained within finitely many wave invariants. Negative spectral results, i.e. differences in connections not determined by spectra, are obtained by constructing transplantations between the Schrödinger operators of two connections with a fixed potential.

Full textMesmo que cientistas tenham demonstrado, até agora, que os materiais utilizados na construção de flautas pouco interferem em suas respectivas características sonoras,parece que algo ainda está em aberto, pois diversos músicos ainda insistem no fato de que o material utilizado na construção de flautas influencia de forma significativa o som produzido. Assim na busca por resultados que possam contribuir nessa discussão, foi realizado um estudo acústico com três pares de tubos de dimensões idênticas,sendo dois de alumínio, dois de cobre e dois de latão, com o propósito de comparar seus respectivos sons harmônicos em três experiências semelhantes: (Experiência 1) tubos acoplados a um bocal de flauta doce,contralto,da marca Yamaha,tocadas por um flautista; (Experiência 2) tubos acoplados a um bocal de flauta transversal,em fibra de carbono,especialmente construído para este trabalho,tocadas por outro flautista; (Experiência 3) tubos acoplados ao mesmo bocal de flauta doce, contralto, da marca Yamaha, tocadas por um soprador artificial alimentado por um cilindro de gás nitrogênio (99,9% de pureza) com fluxo controlado e contínuo.

Full textMost of the recorder teaching methods used throughout Brazil, as we could observe, chiefly contemplate the playing and reading skills development. Furthermore, there is a significant lack of publications specializing on the learning process study. Bearing these facts in mind and based on the author\'s experiments, this research is directed to systemize and analyze the attempts to come up with creative and reflexive plans, and look for approach to the contemporary musical language which would enlarging pedagogic horizons, contribute to the recorder teaching across the country, collaborate with the knowledge production in the area, as well as improving the development of human skills. This research is theoretically based on musical pedagogical principles by two major music educators: Hans-Joachim Koellreutter (1915-2005) and Violeta Hemsy of Gainza (1930-), complemented by other educators thoughts as Paynter (1992), Brito (2001 , 2003, 2004, 2007, 2012), Schafer (1992), Self (1967), Fonterrada (2008), among others who complemented and extended these principles. This research being a work of qualitative nature, among several existing studies, it is characterized as an experience report. The data were collected next to two advanced musical education institutions located in São Paulo: Faculdade de Artes Alcântara Machado (FIAM-FAAM) and Faculdades Integradas Cantareira (F.I.C.), between 2013-2014,as well as with children of the Arts Initiation Municipal School, Escola Municipal de Iniciação Artística (EMIA), between 2008-2012, and with a privately tutored 7- year old student, between 2013-2014.The outcome of those experiments showed that the various educational procedures presented have widened the musical practices, developing the technique of the instrument, both traditional and contemporary. It was also shown that the approach to the XX and XXI centuries\' repertoire when introduced early at the apprenticeship stage was an unusual experience, drawing interest and proving to be enriching and a border dilator to the most of the students. As far as human aspects are concerned, the activities contributed to the development of attentiveness, readiness, promoting autonomy, tolerance, generosity and respect, pointing up to the feasibility for the expansion of the existing methods.

Full textThe present research traces the recorder learning process in a group of seventeen people, between the ages of nine and thirteen, which participate in an extension program held by a public school in Porto Alegre city. This research aims to understand how musicality is developed, based on the concept that this is a human characteristic, constituted by the capacity of creating musical meaning through expressive performance. The methodology applied has a qualitative approach. A group case study was made through class observation and collective recorder presentations. Semi-structured interviews were conducted as a complementary procedure. Data collection occurred between September 2007 and August 2008 by a total of 16 meetings registered in a field diary and in audio files. The observation of indicators such as sonority, musical phrasing, instrumental fluency and musical interaction optimized the analysis and interpretation of the results. The development of musicality in these seventeen people was characterized by the dynamic process of gradual acquisition of musical knowledge and ability, which promotes, at every progress, a new know-how wholeness that favors performance expressivity. The results demonstrated that: repertoire; practice and study; sociocultural context; access to technique, composition, improvisation, and musical reading; and the occurrence of musical presentations are factors that influence musicality development.

Foi baseado em uma série de depoimentos do professor João Dias Carrasqueira recolhido durante o ano de 1993, onde ele relata sua vida como músico e mestre da flauta. Além dos depoimentos do professor João Dias Carrasqueira também foram feitas entrevistas e tomados depoimentos de várias pessoas a ele ligadas.Inicia-se com uma breve biografia, fazendo referência ao cognome Canarinho da Lapa, as primeiras lições de flauta transversal, os primeiros trabalhos profissionais em orquestras de cinema da década de 1920, e a partir da década de 1930, em emissoras de rádio, além de um relato de seu importante trabalho como flautista. Enfatizamos suas idéias aplicadas ao ensino de flauta, fazendo um paralelo com as idéias de outros educadores como Paulo Freire, K.Swanwick e V.Gainza e mestres da música como H.Villa-Lobos, no que se refere à utilização de elementos da própria cultura como veículo de aprendizagem. A utilização da música de câmara e o convívio permanente entre alunos são aspectos relevantes do seu processo de aprendizagem. João Dias Carrasqueira foi um dos primeiros a incluir o repertório de música brasileira no ensino de flauta. Ainda estão relacionados os recursos pedagógicos utilizados por ele com alunos iniciantes e principalmente com crianças como criação de desenhos, histórias e canções.Do ponto de vista técnico, a sonoridade era o aspecto de maior importância para o professor João Dias Carrasqueira. Ele estimulava a prática de exercícios que visassem o aperfeiçoamento da qualidade sonora, sempre respeitando as características individuais de cada estudante. Por último, nós exploramos o significado da expressão Flautosofia criada por João Dias Carrasqueira para manifestar a sua atitude diante da música e da vida.

Resumo: Esta pesquisa teve por objetivo explicitar o papel do espetáculo didático musical Doce Flauta Doce em atividades de apreciação musical do público infantil em ambiente escolar. Foi realizado um diagnóstico prévio do público infantil participante da pesquisa; analisou-se a influência desse espetáculo sobre o interesse das crianças em tocar um instrumento musical, bem como suas impressões e participações diante do espetáculo; e foram especuladas as possibilidades de aprendizagem musical decorrentes do espetáculo. No primeiro capítulo é apresentado o concerto didático como uma forma de ensino musical informal e exemplos de projetos estruturados envolvendo este tema. No capítulo seguinte apresentam-se reflexões de educadores musicais sobre a apreciação musical e sua função no ensino musical. A metodologia adotada foi estudo de caso, que incluiu duas apresentações do espetáculo didático musical Doce Flauta Doce, no ano de 2015, em uma escola pública do município de Curitiba. O instrumento de pesquisa adotado consiste em questionários com três categorias de público participantes desta experiência: as crianças, os professores e os músicos envolvidos, e, complementarmente, em desenhos elaborados pelas crianças após o espetáculo. Pôde-se concluir que as crianças, por meio do espetáculo, entraram em contato com a diversidade de instrumentos, puderam compará-los, analisá-los, e também conhecer como funcionam. Além disso, percebeu-se que quando solicitadas a participar da performance, o grau de engajamento e atenção aumenta consideravelmente. Com esta pesquisa constata-se que o espetáculo didático musical Doce Flauta Doce, por meio da apreciação musical ao vivo, propiciou a aproximação das crianças à música instrumental, com liberdade expressiva, despertando nelas a curiosidade pelo diferente (independente de seu gosto musical), e proporcionando autonomia para que pudessem realizar as suas próprias conexões entre o que viram e escutaram, e suas próprias experiências com a música. Palavras-chave: Flauta doce. Espetáculo didático musical. Apreciação musical. Ambiente escolar.
Abstract: This research aimed to explain the role of the didactic musical spectacle Doce Flauta Doce on music listening of children's audience in the school environment. First, it was made a previous diagnosis of the child audience participant of the research. Then, the influence of this spectacle on children's interest in playing a musical instrument was analyzed, as well as their impressions of the spectacle, and their participation in it. The possibilities of musical learning resulting from the spectacle were speculated. The first chapter presents the didactic concert as a form of informal music teaching and also some examples of structured projects involving this subject. The next chapter presents some reflections of music educators on music listening and their role in music teaching. The methodology used was case study, which included two performances of the didactic musical spectacle Doce Flauta Doce, in 2015, in a public school in the city of Curitiba. The research instrument adopted consisted of questionnaires applied to three categories of people that participated in this experience: children, teachers and musicians. Additionally, the research instrument consisted also of drawings produced by the children after the spectacle. It was possible to conclude that children, thanks to the spectacle, came into contact with the diversity of instruments, could compare them, analyze them, and also know how they work. Moreover, it was noticed that when asked to participate in the performance, the degree of engagement and attention has increased considerably. As a result of this research it appears that the didactic musical spectacle Doce Flauta Doce, through the live music listening, propitiated the approximation of children to the instrumental music, with expressive liberty, awakening in them the curiosity about the unknown (regardless of their musical tastes), and providing them autonomy to make their own connections between what they saw and listened and their own experience with music. Keywords: Recorder. Didactic musical spectacle. Music listening. School environment.

Entre las nuevas demostraciones cabe resaltar la que se refiere a la equivalencia entre sistemas de control lineales en representación de variables de estado, y los módulos sobre un anillo de operadores diferenciales. Los resultados de este estudio son ampliamente utilizados en el desarrollo de otros capítulos de la tesis en los que se usa el álgebra diferencial. En este contexto las principales contribuciones son:
Una nueva demostración del hecho, bien conocido, que la linealización por realimentación estática y la linealización por realimentación dinámica son equivalentes en el caso de sistemas de entrada simple. Para la linealización de este tipo de sistemas, se desarrolla un nuevo algoritmo.
Un procedimiento teórico para linealizar sistemas de entrada múltiple, basado en el cociente de módulos. También se ha hecho un paquete informático para llevar a cabo los cálculos necesarios. Debe mencionarse que este procedimiento es válido para linealizar sistemas mediante realimentación estática, así como para sistemas que sólo puedan linealizarse mediante realimentación dinámica.
Una condición para comprobar si las salidas linealizantes encontradas pueden obtenerse mediante prolongaciones. Como aplicación, se muestran algunos ejemplos de sistemas linealizables por prolongaciones. Algunos de estos sistemas se creían que no eran linealizables mediante esta técnica.

Given a prime number p, Bloch and Kato showed how the p Selmer group of an abelian variety A over a number field K is determined by the p-adic Tate module. In general, the pm1-Selmer group Selpmn A need not be determined by the mod pm Galois representation A[pm]; we show, however, that this is the case if p is large enough. More precisely, we exhibit a finite explicit set of rational primes E depending on K and A, such that Selpm A is determined by A[pm] for all ... In the course of the argument we describe the flat cohomology group ... of the ring of integers of K with coefficients in the pm- torsion A[pm] of the Neron model of A by local conditions for p V E, compare them with the local conditions defining Selm 2A, and prove that A[p't ] itself is determined by A[pm] for such p. Our method sharpens the relationship between Selpm A and ... which was observed by Mazur and continues to work for other isogenies 0 between abelian varieties over global fields provided that deg o is constrained appropriately. To illustrate it, we exhibit resulting explicit rank predictions for the elliptic curve 11A1 over certain families of number fields. Standard glueing techniques developed in the course of the proofs have applications to finite flat group schemes over global bases, permitting us to transfer many of the known local results to the global setting.

Full textENGLISH SUMMARY: It is found that the serviceability limit state often governs the design of slender reinforced concrete members. Slender flexural members often have a percentage tension reinforcement less than 1.0% and an applied bending moment just above the point of first cracking. For such members, the available methods to evaluate the serviceability conditions produce inadequate and unrealistic results. The evaluation of the serviceability of a slender member includes the calculation of the predicted deflection, either by empirical hand-calculation or analysing a finite element model, and the verification using the span-to-effective-depth ratio. The focus of the study is on flat slab structures. It investigates the different deflection prediction methods and the span-to-effective-depth ratio verifications from various design standards. These design standards include the ACI 318 (2002), the SABS 0100-1 (2000), the EC2 (2004) and the BS 8110 (1997). The background to the methods, as well as the parameters which influences the deflection development for lightly reinforced members, are investigated in order to define the limitations of the methods. As a result of the investigation of the deflection calculation methods, an Alternative Approach is suggested and included in the comparisons of the various methods. The deflection prediction methods and the span/effective depth verification procedures are accurately formulated to predict the serviceability behaviour of beams. Additional approaches had to be used to apply these methods to a two-dimensional plane such as that of a flat slab structure. The different deflection prediction methods and the span/effective depth verification methods are calculated and compared to the recorded data of seven experimental flat slab specimens as performed by others. A study by Gilbert and Guo (2005) accurately recorded the flexural behaviour of flat slab specimens under uniformly distributed loads for test periods up to 750 days. The methods to evaluate the serviceability of a slender member were also applied to slab examples designed using South African standards. The study concludes by suggesting a suitable deflection prediction method for different parameter (limitation) categories with which a slender member can comply to. The typical span/effective depth ratio trend is also presented as the percentage tension reinforcement for a slender member changes. It is observed that the empirical hand-calculation methods present more reliable results than those of the finite element models. The empirical hand-calculation methods are accurate depending on the precision to which the slab was constructed relative to the actual slab design. The comparison of the deflection methods with South African case studies identified the role played by construction procedures, material parameters and loading history on slab behaviour.
AFRIKAANSE OPSOMMING: Die diensbaarheidstoestand is in baie gevalle die bepalende faktor vir die ontwerp van slank gewapende beton elemente bepaal. Slank elemente, soos lig bewapende buigbare beton elemente, het gewoonlik ‘n persentasie trekbewapening van minder as 1.0% en ‘n aangewende buigmoment net wat net groter is as die punt waar kraking voorkom. Die metodes beskikbaar om die diensbaarheid van sulke elemente te evalueer gee onvoldoende en onrealistiese resultate. Die evaluering van die elemente in die diensbaarheidstoestand sluit in die bepaling van defleksies deur berekening of die analise van ‘n eindige element model, en die gebruik van die span/effektiewe diepte metode. Die fokus van die studie is platbladstrukture. Die doel van die studie is om die verskillende metodes vir die bereking van defleksie asook die verifikasie volgens span/effektiewe diepte metodes van die verskillende ontwerp standaarde te ondersoek. Die ontwerp standaarde sluit die ACI 318 (2002), SABS 0100-1 (2000), EC2 (2004) en die BS 8110 (1997) in. Die agtergrond van hierdie metodes is ondersoek asook die parameters wat ‘n rol speel, sodat die beperkings van die metodes geidentifiseer kan word. As ‘n gevolg van die ondersoek na die beperkings van die metodes, is ‘n Alternatiewe Benadering voorgestel. Die Alternatiewe Benadering is saam met die metodes van die ontwerpstandaarde gebruik om die verskille tussen die metodes te evalueer. Die defleksievoorspelling en die span/effektiewe diepte verifikasie metodes is korrek geformuleer om die diensbaarheid van balke te evalueer. Ander benaderings was nodig om die diensbaarheid van blad blaaie te toets. Die onderskeie defleksievoorspelling en span/effektiewe diepte metodes is bereken vir sewe eksperimentele plat blaaie soos uitgevoer deur ander navorsers. Gilbert and Guo (2005) het ‘n studie uitgevoer waar die buigingsgedrag van die sewe plat blaaie, met ‘n uniforme verspreide las vir ‘n toetsperiode van tot 750 dae, akkuraat genoteer is. Die metodes om die diensbaarheid van ‘n slank element te toets, was ook op Suid-Afrikaanse blad voorbeelde getoets. Dit was gedoen om die Suid- Afrikaanse ontwerp van ligte bewapende beton elemente te evalueer. Die gevolgetrekkings stel ‘n gepaste defleksie metode vir ‘n slank element vir verskillende beperking kategorië voor. Dit is ook verduidelik hoe die tipiese span/effektiewe diepte verhouding met die persentasie trek bewapening vir ‘n slank element verander. Dit is bevind dat die imperiese handmetodes om defleksies te bereken, meer betroubaar as die eindige element modelle se resultate is. Die imperiese handberekening metodes is akkuraat relatief tot hoe akkuraat die blad konstruksie tot die blad ontwerp voltooi is. ‘n Vergelyking van defleksieberekening met Suid-Afrikaanse gevallestudies het die belangrikheid van konstruksieprosedures, materiallparamteres and belastingsgeskiedenis geïdentifiseer.

Full textLinear induction motors are built for numerous applications. Their robustness, gearfree-link to the load and the fact that speed is not a function of the number of poles (as in round machines) are only a few advantages. As every single phase motor needs some starting aid, so does a linear induction drive. For round machines, capacitors or shaded poles are usually used. A capacitor can be damaged electrically, which is a rare occurrence for shading rings. A useful combination of these advantages is a linear induction motor which is gearless and uses the shaded pole principle as a starting aid. In order to simplify the designing process, a computer program (Fortran) was written. The main objective on the electrical side was to obtain low input power, high power factor and high efficiency. In order to find the performance curves, torque measurements were made. Although the principles of torque measurements are well known the device to measure torque for this machine was not available and had to be constructed.

Resumo: Esta pesquisa qualitativa teve como objetivo obter informações sobre estratégias de estudo de alunos de flauta transversal e, ao final, apontar sugestões para melhorias nesse estudo. Inicialmente, foi feita uma revisão histórica acerca do estudo da flauta transversal para situar as maneiras em que o ensino e aprendizado deste instrumento se desenvolveram. Abordou-se as caraterísticas da relação mestre-aprendiz, tendo como referência o tratado de Quantz, até chegar ao ensino sistematizado por meio da instituição conservatório como escola profissionalizante. A seguir, foi feita uma entrevista estruturada com seis estudantes de flauta de uma instituição de ensino superior (IES) brasileira, buscando extrair informações sobre as práticas de estudo dos alunos e sua formação musical. A partir das entrevistas, com base na análise de conteúdo de Laurence Bardin (2008), foram criadas quatro categorias abordando questões acerca dos modelos propostos pela tradição de ensino conservatorial, priorizando a aquisição de habilidades técnicas e, também, da organização de estratégias aplicadas no estudo diário que beneficiam o aprimoramento da performance. A análise de conteúdo dos relatos coletados apontou que o modelo de ensino tecnicista ainda é adotado como principal escolha entre os sujeitos investigados. As discussões apontam para um estudo que contemple um pensamento mais reflexivo, que possa beneficiar o planejamento de estratégias e adaptá-las às necessidades de cada indivíduo, otimizando assim o tempo e visando a uma prática eficaz
Abstract: This qualitative research aimed to obtain information about study strategies of undergraduate flute students and, at the end, to point to suggestions to improve the practice of the instrument. To begin with, we did an historical review of the study of the flute to situate the ways in which the teaching and learning of the instrument have developed. We have approached the features of the relationship between master-apprentice based on the treaty of Quantz, reaching a systematized study at the conservatory as a technical model . Second, we did a semi-structured interview with a group of six undergraduate flute students of a Brazilian university, searching for information about how they practice the instrument daily, and how they relate their practice with their own musical formation. After the interview, we created four categories approaching issues about the traditional models to learn that prioritize study of technical skills, and also about the organizing strategies applied in daily study to fully improve the performance, based on Laurence Bardin's analysis (2008). The results of analysis' contents of the collected reports shows that the technicist model of education is still adopted as the main choice among the investigated subjects. In the discussion, we point to ways of studying that contemplate a more reflexive thinking that can benefit planning strategies and adapt them to the needs of each individual thus optimizing the time and seeking an effective practice

Full textTocar um instrumento musical exige grande esforço físico por parte do instrumentista. Devido ao esforço repetitivo, o corpo de um instrumentista pode sofrer alguns problemas físicos provenientes do estudo e da performance do seu instrumento, e consequentemente gerar lesões musculoesqueléticas, dores e desconfortos. Os flautistas não fogem a esta regra. Apesar da relevância, poucos são os estudos que têm abordado as demandas físicas do estudo da flauta. O presente estudo investigou problemas físicos detetados em músicos, com ênfase nos instrumentistas de flauta transversal, e se estes podem ser amenizados ou mesmo tratados com a realização de exercícios de relaxamento antes e após da performance da flauta. É também abordado o caso de tomada de consciência – propriocepção- como benefício para a performance e prática musical.
Playing a musical instrument requires great physical effort from the musician. Duet to repetitive stress, the musician´s body can suffer some physical problems from study and performance of his/her own instrument, and consequently generate musculoskeletal injuries, aches and pains. Flautists are no exception to this rule. Despite its relevance, there are just a few studies that have addressed the physical demands of the flute´s study. This specific study has investigated physical problems detected in musicians, with an emphasis on flute instrumentalists, and if these can be alleviated or even treated with relaxation exercises before and after the performance of the flute. It is also addressed the case of self awareness – proprioception - as a benefit for performance and musical practice.

Full textThe aim of this research was to study the creative principles (poetics) that guide flutists’ decisions regarding the preparation of new pieces of contemporary music, which involve extended techniques and non-traditional notation, in order to conceive of a set of practices for interpreting new works from reading the score without listening to previous interpretations, and also the pedagogical application of these principles. To access how decisions are made during the construction of an interpretation of contemporary music, a field study was conducted in which three professional flutists, who usually première pieces of new music, and four undergraduate students recorded, in audio/video, the process of reading and interpretating three miniatures for solo flute composed especially for this research, verbalizing their process of interpretive decisions; an interview after the final performance of the pieces complemented data collection. Methodologically based on Grounded Theory, a categorization of these verbalizations was created and the aspects raised were encompassed in: preliminary reading, basic dimensions and interpretative dimensions of the performance. The hermeneutic philosophy as a study of interpretation, especially Hans-Georg Gadamer and Luigi Pareyson, and particularly the concept of “truth”of the art work, shed light for the analysis of the collected data. Considerations about the development of a performer’s autonomy, taking into account the concepts of self-regulation and auto-maieutics and the analysis of the field study, complement each other in a pedagogical proposal for approaching unknown works that involve extended techniques by means of reading scores only. It is understood that the inclusion of contemporary works that involve new sonorities and extended techniques during the training of students is essential so that repertoire developed from the mid-20th century is not neglected and students’ preparation becomes more comprehensive.
L’obiettivo di questa ricerca è stato quello di studiare i principi creativi (le poetiche) che guidano le decisioni dei flautisti nella preparazione di nuovi brani di musica contemporanea che includono tecniche estese e notazioni non tradizionali, al fine sia di concepire un insieme di pratiche interpretative di opere nuove partendo dalla lettura della partitura, senza ascoltare interpretazioni precedenti, sia di elaborare delle applicazioni di questi principi in ambito didattico-pedagogico. Al fine di indagare come vengono prese le decisioni durante la costruzione di un’interpretazione di musica contemporanea, è stato condotto uno studio sul campo nel quale tre flautisti professionisti che solitamente eseguono in prima assoluta pezzi di nuova musica e quattro studenti universitari hanno registrato, in audio/video, il processo di lettura e interpretazione di miniature per flauto solo composte appositamente per questa ricerca, verbalizzando il loro processo decisionale; un’intervista dopo l’esecuzione finale dei pezzi ha completato la raccolta dati. Sulla base metodologica della Grounded Theory, è stata creata una categorizzazione di queste verbalizzazioni e gli aspetti sollevati sono stati raccolti nelle seguenti categorie: lettura preliminare, dimensioni di base e dimensioni interpretative della performance. La filosofia ermeneutica come studio dell’interpretazione, in particolare le opere di Hans-Georg Gadamer e Luigi Pareyson, e più specificamente il concetto di “verità” dell’opera d’arte, hanno fatto luce sull’analisi dei dati raccolti. Le considerazioni sullo sviluppo dell’autonomia dell’interprete, tenendo conto i concetti di “autoregolazione” e “auto-maieutica” e i risultati dello studio sul campo, si completano in una proposta pedagogica di avvicinamento a opere sconosciute che coinvolgono tecniche estese attraverso la sola lettura delle partiture. Si riconosce che l’inclusione di opere contemporanee che includono nuove sonorità e tecniche estese durante la formazione degli studenti è essenziale sia affinché il repertorio flautistico sviluppato sin dalla metà del XX secolo non sia trascurato sia per una più completa preparazione degli studenti.

Full textThe main purpose of this report, is to evaluate feasibility of using The Global Positioning System as an aiding tool for vehicle state estimation based on nonlinear techniques, and to develop a potential solution to the road bank angle problem. Previous work within the CEmACS project, includes development of a general nonlinear observer for lateral and longitudinal velocity, and an augmentation in the form of road-tire friction adaptation. Because the existing solutions have been shown to lack robustness with regards to certain disturbances, such as road grade and road bank angle, it has been stated that the estimation scheme should be upgraded, so that these disturbances can be accounted for. By including GPS velocity or a or a roll rate gyro measurement in the observer feedback loop, the possibility of detecting previously inobservable quantities is gained. In simple terms, evaluation of feasibility corresponds to demonstrating improvements and limitations of new solutions, using relatively crude methods in the test procedures. Problems related to the above mentioned task, are approached by means of signal processing and control theory. Following an intuitive sequence of operations, the report presents GPS theory and results first, as this lays the foundation for all subsequent results. Methods used comprise simple differentiaton, rotational kinematics and discrete filtering. Secondly, theory and results related to nonlinear observers, with focus on GPS aiding, are examined thoroughly. Lyapunov theory, known from control engineering, is used to evaluate stability, while data from simulations and actual vehicle tests is used to show how a new observer scheme can improve existing solutions. Before the most important results are presented, something should be said about their accuracy and significance. It has already been pointed out that the methods used are not based on optimality requirements, and consequently the results are best viewed as indicators of potential, rather than absolute solutions. This is especially true for the GPS velocity calculations, which are based on differentiation of position measurements; generally not a desired approach. In this report, it is firstly shown that GPS position measurements can be used to compute receiver velocity in the body-fixed coordinate frame. While this is a crude approach, resulting in relatively poor signal to noise ratio, it is easily implemented on low-level equipment. It is also shown that it is possible to use these velocities as measurements in a nonlinear observer structure, slightly modified from previous solutions within the CEmACS project. By doing this, accurate estimates of road grade and bank v angle are achieved, so long as these vary slowly enough. Stability of the observer is not proven in the general sense, but it is shown that it can be made stable through realistic assumptions and gain selection. Stability is further demonstrated through the use of data sets from actual vehicle tests. Secondly, a mathematical model of roll dynamics is combined with a roll rate measurement to create the possibility of detecting road bank angle. This is done by the now familiar nonlinear observer approach. Usefulness is demonstrated by simulations, but no stability proof is presented. The main conclusion is that it is feasible to use GPS aiding to account for robustness problems in a vehicle state estimation scheme, and that the inclusion of a roll rate measurement opens up possibilities for cheap bank angle detection. A direct implementation of results presented in the report may not be ideal, but the fact that the system works for a large set of conditions, suggests that it is worthwhile to develop it further. This is especially true when it is assumed that GPS receivers will become an integral part of new vehicles in the near future. Refinements and upgrades can be made in the form of more advanced GPS technology, new parameter estimation techniques and integration with the road-tire friction adaptation scheme.
