    This article discusses the development of the Mobile Csound Platform (MCP), a group of related projects that aim to provide support for sound synthesis and processing under various new environments. Csound is itself an established computer music system, derived from the MUSIC N paradigm, which allows various uses and applications through its Application Programming Interface (API). In the article, we discuss these uses and introduce the three environments under which the MCP is being run. The projects designed for mobile operating systems, iOS and Android, are discussed from a technical point of view, exploring the development of the CsoundObj toolkit, which is built on top of the Csound host API. In addition to these, we also discuss a web deployment solution, which allows for Csound applications on desktop operating systems without prior installation. The article concludes with some notes on future developments

    This paper focuses the prototyping stage of the design cycle of ubiquitous music (ubimus) ecosystems. We present three case studies of prototype deployments for creative musical activities. The first case exemplifies a ubimus system for synchronous musical interaction using a hybrid Java-JavaScript development platform, mow3s-ecolab. The second case study makes use of the HTML5 Web Audio library to implement a loop-based sequencer. The third prototype - an HTML-controlled sine-wave oscillator - provides an example of using the Chromium open-source sand-boxing technology Portable Native Client (PNaCl) platform for audio programming on the web. This new approach involved porting the Csound language and audio engine to the PNaCl web technology. The Csound PNaCl environment provides programming tools for ubiquitous audio applications that go beyond the HTML5 Web Audio framework. The limitations and advantages of the three approaches proposed - the hybrid Java/- JavaScript environment, the HTML5 audio library and the Csound PNaCl infrastructure - are discussed in the context of rapid prototyping of ubimus ecosystems

    No âmbito do mestrado em Ensino dos 1.º e 2.º Ciclos do Ensino Básico, foram realizados dois estágios profissionais: um ano no 1.º ciclo e outro a lecionar em turmas do 2.º CEB. Este relatório final prevê a reflexão sobre esses mesmos estágios e, ainda, inclui uma linha de trabalho investigativo. Assim, este documento resume-se, essencialmente, a três partes. Na primeira, referente à investigação, exploram-se os resultados associados a um estágio realizado em algumas escolas escocesas, na periferia de Glasgow. Aqui lecionou-se Português como Língua Estrangeira (PLE), introduzindo o Português nestas escolas. Nesta investigação analisa-se o sistema de ensino escocês, explora-se a documentação existente associada ao PLE, descrevem-se as atividades e discutem-se os resultados. A segunda parte diz respeito ao 1.º ciclo e aí caracteriza-se o contexto da intervenção, fundamentam-se as opções metodológicas, reflete-se sobre as aulas e ainda se salientam algumas experiências-chave. A terceira parte refere-se ao estágio em 2.º ciclo Aí se caracteriza o contexto da intervenção para cada uma das disciplinas (Português, Matemática, História e Geografia de Portugal e Ciências Naturais) e se fundamentam as estratégias adotadas e se reflete sobre as aulas. No final do documento tecem-se, ainda, algumas considerações finais

    A equipa B é um patamar intermédio entre a formação do clube e a sua equipa principal. Tem objetivos distintos das demais equipas, por se tratar de uma equipa com características diferentes, sendo um espaço para desenvolvimento dos jovens jogadores oriundos da formação do clube. Este relatório procura demostrar as ideias e objetivos por detrás da equipa B do Sport Lisboa e Benfica, sendo apresentado a forma de operacionalizar o processo de treino e de jogo através do seu i) modelo de treino, ii) modelo de jogo e iii) modelo de observação e avaliação do desempenho em jogo. Estes três ‘pilares’ representam de forma concisa o processo de desenvolvimento de jogadores na equipa B do Sport Lisboa e Benfica e os seus procedimentos específicos de operacionalização do trabalho desenvolvido. A recolha do conhecimento destas áreas mencionadas, conseguiu-se pela integração na equipa técnica da equipa B. Com integração e experiência vivenciada nestas diferentes áreas, à qual se adicionou a pesquisa e revisão de literatura, resultou uma reflexão aprofundada sobre os referenciais teórico-práticos subjacentes ao trabalho desenvolvido. Mais especificamente: i) analisaram-se os comportamentos pretendidos, coletiva e individualmente, compondo assim o modelo de jogo da equipa B; ii) analisou-se um exemplo de um microciclo padrão com exercícios que dão forma e corpo à ideia de jogo que se pretendeu implementar; iii) clarificou-se o foco e objetivo da observação e análise da própria equipa e do adversário, tanto coletiva como individualmente. Desenvolveu-se ainda um projeto de investigação, utilizando métodos mistos, com o objetivo de estudar a eficiência da equipa B na transição dos jogadores da formação para o Futebol profissional. Este estudo comparou os volumes de jogo em dois períodos distintos. No primeiro período não existia equipa B no clube. No segundo período já existia a possibilidade de os jogadores da formação competirem na equipa B do Sport Lisboa e Benfica. Aliado à análise dos volumes de jogo dos jogadores do Sport Lisboa e Benfica, foi realizado um conjunto de entrevistas à equipa técnica de modo a extrair, de uma forma qualitativa, as ideias-chave do projeto da equipa B no seio do clube. Os resultados ajudam a esclarecer que a equipa B reúne inúmeras vantagens no que respeita à eficiência da transição para o futebol profissional no contexto do clube analisado. Na área de relação com a comunidade, desenvolveu-se na Faculdade de Motricidade Humana, o 4º Dia do Futebol da FMH, sob o título: “As Diferentes Dimensões do Processo de Treino no Futebol”. Este evento teve como objetivo dar a conhecer a todos os agentes desportivos as diversas especializações e formas de intervenção profissional no âmbito de uma equipa técnica, como por exemplo, a observação e análise, a fisiologia e a preparação física, o desenvolvimento individual dos jogadores, a planificação estratégico-tática e o treino de guarda-redesThe B team is an intermediary level between the formation of the club and its main team. It has different goals from the other teams, because it is a team with different characteristics, where it is intended to be a space for the development of young players from the formation of the club. This report has a demonstration of ideas and goals behind the Sport Lisboa Benfica B team, presenting a form of operation of the training and game process through its, training model, ii) game model and iii ) model of observation and evaluation of the performance in game. These three 'pillars' represent in a concise way the process of developing players in B Team of Sport Lisboa Benfica and their own procedures to operationalize the work developed. A collection of knowledge about the areas mentioned was achieved through integration into the technical team. Integration and lived experience in these areas, as the literature research and revision was added, a thorough reflection on the theoretical-practical frameworks resulted. underlying the work developed. More specifically: i) the intended behaviors were analyzed collectively and individually, composing as game model of B team ii) analyze an example of a standard microcycle with exercises that give shape and body to the idea of the game that was intended to be implemented; iii) clarified the focus and objective of the analysis and observation of the team and the opponent, both collectively and individually. A research project was developed, using mixed methods, aiming to study the efficiency of B team in the transition of players from the formation to the professional football. This study compares game volumes into two distinct periods. In the first period did not exist B team in the club. In the second period there was already a possibility of the players of the formation competing in the B team of Sport Lisboa Benfica. Combined with the analysis of the game volumes of the players of Sport Lisboa and Benfica, a set of interviews to the technical team were carried out in order to extract, in a qualitative way, the key ideas of the B team project within the club. The results help to clarify that B Team has many advantages in terms of the economy of transition to professional football in the context of the club analyzed. In the area of relationship with a community, the 4º FMH Football Day was developed at the Faculty of Human Kinetics under the title: "The Different Dimensions of the Football Training Process". This event had the objective of making all sports agents known as various specializations and forms of professional intervention, such as observation and analysis, physiology and physical preparation, individual player development, strategic-tactical planning and goalkeeper trainin

    Improving modularity, interoperability and extensibility in Ambient Intelligence

    Ambient Intelligence (AmI) and its related elds emerged some years ago with the exciting promise of pervasive intelligence, magic interaction mechanisms, and everywhere availability. This promise would be materialized in homes that knew all about our habits and preferences, proactive workplaces to support people's work or personal digital assistants to improve our daily living in all aspects possible. This somewhat utopian vision, expected by many to have already taken place, remains unaccomplished and far from it. Many challenges still lay ahead which delayed and continue to delay the expected technological unravelling. In this paper we focus on the immense technological challenges of designing and implementing AmI Systems. Speci cally, we propose a technological approach that will contribute to overcome some of these challenges by making developed AmI solutions more modular, interoperable, and extensible. This will result especially advantageous for large development teams or teams that span multiple institutions.This work is part-funded by ERDF - European Regional Development Fund through the COMPETE Programme (operational programme for competitiveness) and by National Funds through the FCT - Fundação para a Ciência e a Tecnologia (Portuguese Foundation for Science and Technology) within project FCOMP-01-0124-FEDER-028980 (PTDC/EEI-SII/1386/2012)

    Gravitational diffraction radiation

    Get PDF
    We show that if the visible universe is a membrane embedded in a higher-dimensional space, particles in uniform motion radiate gravitational waves because of spacetime lumpiness. This phenomenon is analogous to the electromagnetic diffraction radiation of a charge moving near to a metallic grating. In the gravitational case, the role of the metallic grating is played by the inhomogeneities of the extra-dimensional space, such as a hidden brane. We derive a general formula for gravitational diffraction radiation and apply it to a higher-dimensional scenario with flat compact extra dimensions. Gravitational diffraction radiation may carry away a significant portion of the particle's initial energy. This allows to set stringent limits on the scale of brane perturbations. Physical effects of gravitational diffraction radiation are briefly discussed.Comment: 5 pages, 2 figures, RevTeX4. v2: References added. Version to appear in Phys. Rev.
