Enhance Inter-service Communication in Supersonic K-Native REST-based Java Microservice Architectures

Buono, Vincenzo, Petrovic, Petar January 2021 (has links)
The accelerating progress in network speeds and computing power permitted the architectural design paradigm to shift from monolithic applications to microservices. The industry moved from single-core and multi-threads, code-heavy applications, running on giant machines 24/7 to smaller machines, multi-cores single threads where computing power and memory consumption are managed very critically. With the advent of this novel approach to designing systems, traditional multi-tier applications have been broken down into hundreds of microservices that can be easily moved around, start, and stop quickly. In this context, scaling assumed a new meaning, rather than scaling up by adding more resources or computing power, now systems are scaled dynamically by adding more microservices instances. This contribution proposes a theoretical study and a practical experiment to investigate, compare and outline the performance improvements aid by the implementation of Protocol Buffers, Google's language-neutral, binary-based representational data interchange format over traditional text-based serialization formats in a modern, Cloud-Native, REST-based Java Microservice architecture. Findings are presented showing promising results regarding the implementation of Protobuf, with a significant reduction in response time (25.1% faster in the best-case scenario) and smaller payload size (72.28% better in the best-case scenario) when compared to traditional textual serialization formats while literature revealed out-of-the-box mechanisms for message versioning with backward compatibility.

Participatory Design at a distance

Haglund, Chomphunut January 2013 (has links)
Participatory design approach emphasizes user involvement to contribute to interactive systems throughout the design process. The potential user participates in many activities in different physical meetings and workshops. This approach helps the designers to develop better tools to support users work but it is difficult to get them to co-design at the same place and time for many reasons. I have also experienced this kind of difficulty in the school projects involving users in the design process. Many new technologies nowadays have been introduced and used for different purposes so I have asked myself how I can use this to get control over this kind of difficulty. And how to bring people together online to co- design instead of having any physical workshops. Today, many online technologies are used to facilitate PD activities and bring the potential users together regardless of time and space. Some researchers have investigated online media platforms that people are familiar with, for example Facebook to reach their users. Some of them use online tools developed for conducting participatory design online.This study investigates how to design remote/online meeting formats to engage people with different media habits in the early stages of participatory design to get inspiration for redesigning a website. It is very important for a participatory design at a distance to understand and adapt to individual media habits and technological skills because this aspect is crucial for the success of bringing the participants together online and persuade them to contribute including making them willing to involve and perform their online work tasks. The project facilitator should get to know already in the beginning of the project about different communication ways that each participant prefers and usually uses in their daily life. To make sure that the facilitator can reach the potential users and bring them to collaborate online and give their contribution to a design in time. This study shows also that the relation between the participants and the temple or the facilitator is crucial for the success of getting them to contribute. Another aspect that the facilitator needs to take into account is to know about the users’ technological background. This can be used as basic information to choose online tools or media platforms to design online meeting formats to engage people in the design process. The tools that match the participants’ skills make them focus more on their work tasks rather than technical issues. But even if someone has high computer skills, it does not mean that he wants to work with whatever tools in some online activities, the facilitator has to adapt according to what they prefer or give them choices and flexibility. In addition, it is not enough only to observe and provide different channels for the participants to get feedback. It is hard to observe people working online and not everyone says what they think to the facilitator. To know how the users interact with and think about different online meeting formats during the design project by doing feedback interview after each PD stage helps the facilitator to improve online meeting formats for the next steps. The facilitator gets possibilities to repeat and clarify some issues during the project, encourages the participant to continue or contribute more, and prepares them for the next steps. The participants get better understanding of the project and motivation to move on.

Novel 5G-Modulation Formats and Their Application in Optical Wireless Communications

Bahaaelden, Mohammed S. 27 May 2024 (has links)
[ES] La red de sexta generación (6G) es la solución potencial para satisfacer los requisitos exponencialmente crecientes de los servicios y aplicaciones emergentes. La plataforma 6G espera ofrecer altas velocidades de datos, conectividad ultra alta y baja latencia en función de los indicadores clave de rendimiento (KPI) requeridos. La tecnología de comunicación por luz visible (VLC) representa una tecnología clave para la red 6G, pero requiere una técnica de modulación avanzada eficiente para cumplir con dichos requisitos. En las últimas décadas, las señales ópticas basadas en el esquema de multiplexación por división de frecuencia ortogonal (OFDM) han atraído mucha atención y se han convertido en la modulación más popular entre varios esquemas de acceso multiportadora, gracias a su robustez y simplicidad frente a la cancelación por trayectos múltiples utilizando el prefijo cíclico (CP). Una de las formas de onda más prometedoras para redes de próxima generación es la técnica de modulación Filter Bank MultiCarrier (FBMC). El principal beneficio del esquema FBMC es que no depende de CP y de un gran número de muestras de banda de guarda, por lo tanto, emplea varias funciones de pulso localizadas en el tiempo con una alta relación de supresión de lóbulos laterales, lo que permite mejorar la eficiencia espectral y el rendimiento del sistema como factores clave en las redes ópticas de próxima generación, y proporciona una buena alternativa a la técnica CP-OFDM. Esta Tesis pretende dar un paso adelante en la propuesta de formatos de modulación para ser utilizados en sistemas VLC como tecnología habilitadora en redes 6G. Por lo tanto, se propone el sistema Flip-FBMC con un algoritmo de truncamiento para ofrecer una transmisión de alta velocidad con baja latencia Flip-FBMC mediante el uso del algoritmo de transformación ortogonal isotrópica (IOTA) y la capa PHYsical para DYnamic AccesS y filtros de radio cognitiva (PHYDYAS). En esta Tesis se propone la ecualización multitap con el fin de mitigar la Interferencia imaginaria intrínseca (IMI) en un canal con perfiles de retardos elevado en sistemas VLC de interiores. Además, se ha mejorado rendimiento de error de las señales FBMC no coherentes mediante el análisis de la propiedad de la localización de tiempo-frecuencia con la función gaussiana extendida (EGF), donde el factor de dispersión desempeña un papel crucial en la determinación del equilibrio entre las características espectrales y la reconstrucción óptima de la calidad de la señal. Además, la Tesis proporciona el primer análisis teórico que informa de la degradación en la estimación para varios factores de clipping basada en el impacto del nivel de interferencia imaginario fuera de la zona de primer orden que no puede ser estimada mediante el preámbulo de IAM. Sin embargo, se debe enfatizar en el valor de la técnica Flip-FBMC/IAM para proporcionar el modelo unipolar en comparación con el uso del formato FBMC óptico polarizado con corriente continua (DCO-FBMC) que sufre una reducción en la estimación de la precisión. Por lo tanto, se ha demostrado el descenso del rendimiento con el sistema DCO-FBMC debido al IMI inducido fuera de los símbolos de orden cero, y que es más evidente cuando se requieren niveles bajos de corriente DC. Desde esta perspectiva, la técnica de repetición de tramas con señales Flip-FBMC ha demostrado ser una solución importante para minimizar la interferencia inducida. Por lo tanto, en esta Tesis, la modulación Flip-FBMC con repetición de tramas y perfil de filtro PHYDYAS se propone como un candidato viable para hacer frente al rango dinámico restringido del LED, en comparación con el rendimiento de los sistemas Flip-CP-OFDM y Flip-FBMC/IAM en futuras redes 6G basadas en acceso VLC. / [CA] La xarxa de sexta generació (6G) és la solució potencial per a satisfer els requisits exponencialment creixents dels servicis i aplicacions emergents. La plataforma 6G espera oferir altes velocitats de dades, connectivitat ultra alta i baixa latència en funció dels indicadors clau de rendiment (KPI) requerits. La tecnologia de comunicació per llum visible (VLC) representa una tecnologia clau per a la xarxa 6G, però requerix una tècnica de modulació avançada eficient per a complir amb estos requisits. En les últimes dècades, els senyals òptics basats en l'esquema de multiplexació per divisió de freqüència ortogonal (OFDM) han atret molta atenció i s'han convertit en la modulació més popular entre diversos esquemes d'accés multiportadora, gràcies a la seua robustesa i simplicitat enfront de la cancel·lació per trajectes múltiples utilitzant el prefix cíclic (CP). Una de les formes d'ona més prometedores per a xarxes de pròxima generació és la tècnica de modulació Filter Bank MultiCarrier (FBMC). El principal benefici de l'esquema FBMC és que no depén de CP i d'un gran nombre de mostres de banda de guarda, per tant, empra diverses funcions de pols localitzades en el temps amb una alta relació de supressió de lòbuls laterals, la qual cosa permet millorar l'eficiència espectral i el rendiment del sistema com a factors clau en les xarxes òptiques de pròxima generació, i proporciona una bona alternativa a la tècnica CP-OFDM. Esta Tesi pretén fer un pas avant en la proposta de formats de modulació per a ser utilitzats en sistemes VLC com a tecnologia habilitadora en xarxes 6G. Per tant, es proposa el sistema Flip-FBMC amb un algoritme de truncament per a oferir una transmissió d'alta velocitat amb baixa latència Flip-FBMC mitjançant l'ús de l'algoritme de transformació ortogonal isotròpica (IOTA) i la capa PHYsical per a DYnamic AccesS i filtres de ràdio cognitiva (PHYDYAS). En aquesta Tesi, es proposa l'equalització multitap per als sistemes VLC en interiors per a mitigar la interferència imaginària intrínseca (IMI) en un canal amb perfils de retards elevat. A més, el rendiment d'error dels senyals FBMC no coherents es millora mitjançant l'anàlisi de la propietat de la localització de temps-freqüència amb la funció gaussiana estesa (EGF), on el factor de dispersió exercix un paper crucial en la determinació de l'equilibri entre les característiques espectrals i la reconstrucció òptima de la qualitat del senyal. En tal escenari, a causa del rang dinàmic limitat del díode emissor de llum (LED), la millora de la precisió de l'estimació depén dels nivells de potència dels pseudopilots amb l'ús de l'arquitectura del Mètode d'Aproximació d'Interferència (IAM) i per tant, no és adequada en sistemes VLC d'il·luminació i comunicació. A més, la Tesi proporciona la primera anàlisi teòrica que informa de la degradació en l'estimació per a diversos factors de clipping basada en l'impacte del nivell d'interferència imaginari fora de la zona de primer orde que no pot ser estimada mitjançant el preàmbul de IAM. No obstant això, s'ha d'emfatitzar en el valor de la tècnica Flip-FBMC/IAM per a proporcionar el model unipolar en comparació amb l'ús del format FBMC òptic polaritzat amb corrent continu (DCO-FBMC) que patix una reducció en l'estimació de la precisió. Per tant, s'ha demostrat el descens del rendiment amb el sistema DCO-FBMC a causa del IMI induït fora dels símbols d'orde zero, i que és més evident quan es requerixen nivells baixos de corrent DC. Des d'esta perspectiva, la tècnica de repetició de trames amb senyals Flip-FBMC ha demostrat ser una solució important per a minimitzar la interferència induïda. Per tant, en esta Tesi, la modulació Flip-FBMC amb repetició de trames i perfil de filtre PHYDYAS es proposa com un candidat viable per a fer front al rang dinàmic restringit del LED, en comparació amb el rendiment dels sistemes Flip-CP-OFDM i Flip-FBMC/IAM en futures xarxes 6G basades en accés VLC. / [EN] The sixth generation (6G) network is the potential solution to meet the exponentially increasing requirements of the emerging services and applications. The 6G platform expects to offer high data rates, ultra-high connectivity, and low latency based on the required key performance indicators (KPIs). The visible light communication (VLC) technology represents a key technology for 6G network but requires an efficient advanced modulation technique to support such requirements. In the last decades, optical signals based on Orthogonal Frequency Division Multiplexing (OFDM) scheme has attracted a lot of attention and become the most popular modulation among several multicarrier access schemes, thanks to its robustness and simplicity against multipath fading using the cyclic prefix (CP). One of the most candidate waveforms that is considered as the promising modulation technique for the next generation requirements and applications is Filter Bank MultiCarrier (FBMC) multiplexing. The major benefit of FBMC scheme is non-reliance on CP and high numbers of guard band samples, thereby, it employs several well time-frequency localized pulse functions with high side-lobe suppression ratio instead, which allows enhancing the spectral efficiency and system performance as key factors in next generation optical networks, and provides a good alternative to CP-OFDM technique. This Thesis aims to make a step forward in proposing modulation formats to be used in VLC systems as enabling technology in 6G networks. Hence, Flip-FBMC system with a truncation algorithm is proposed to offer a high-speed transmission with low latency by tackling the doubled-overhead tails at the subframes of Flip-FBMC burst by the use of the isotropic orthogonal transformation algorithm (IOTA) and PHYsical layer for DYnamic AccesS and cognitive radio (PHYDYAS) filters. Multitap equalization is proposed in this Thesis for the sake of mitigating the intrinsic imaginary interference (IMI) over a channel with high delays profile for indoor VLC system. Moreover, the error performance of non-coherent FBMC signals is enhanced by analysing the property of time-frequency localization with Extended Gaussian Function (EGF), where the spreading factor plays a crucial role in determining the trade-off between the spectral features and optimal reconstruction of signal quality. In such scenario, due to the limited dynamic range of light emitting diode (LED), improving in the accuracy of estimation depends on the power-levels of pseudo pilots with the use of Interference Approximation Method (IAM) architecture. Thereby, the analysis reveals that IAM sequence is not suitable for a real transmission scenario due to high power of IAM over the payload data which conflicts with VLC purposes of illumination and communication simultaneously. Additionally, the Thesis provides the first theoretical analysis reporting the degradation of estimation accuracy for several clipping ratios based on the impact of imaginary interference level outside the first order neighbourhood zone that cannot be estimated by IAM preamble. However, the value of Flip-FBMC/IAM technique in providing the unipolar model must be emphasized compared to the use of Direct Current biased Optical FBMC (DCO-FBMC) format that suffers from a reduction in estimating accuracy. Thereby, the downfall performance with DCO-FBMC system has been reported because of the induced IMI that spreads out the first neighbourhood symbols, which is more evident when low levels of the added DC-bias are required. From such perspective, the frame repetition technique with Flip-FBMC signals has been demonstrated as a major solution for minimizing the induced interference. Therefore, in this Thesis, Flip-FBMC/frame repetition with PHYDYAS profile is proposed as a viable candidate to cope with the restricted dynamic range of the LED, compared to the performance for each Flip-CP-OFDM and Flip-FBMC/IAM system in future 6G networks based on VLC access. / Bahaaelden, MS.

How Professional Development Supported Principals as Instructional Leaders Within Two School Divisions in Virginia: A Qualitative Investigation

Hall, Rebecca Bienvenue 11 April 2024 (has links)
Principals have an impact on the teaching and learning that takes place in their schools. This research focuses on principal involvement in professional development (PD) to meet policy requirements while developing principals' skills to meet their changing roles to serve as instructional leaders accountable for student academic performance. The purpose of this qualitative study was to identify the types of PD principals and principal supervisors find most beneficial in developing principals' instructional leadership skills along with the perceived benefits and challenges of participating in PD designed for the principalship role. The secondary purpose was to identify the impact principal PD may have on instructional leadership practices and student achievement. The two research questions were: What types of PD do principals and principal supervisors find most impactful to developing principals' instructional leadership skills? What are the perceived benefits and challenges of participating in virtual, hybrid, and in-person PD specifically designed for the principalship role? A demographic survey and one-on-one, semi-structured interviews were completed with five elementary school principals, four secondary school principals, and three principal supervisors from a rural and suburban school division in Virginia. Deductive coding was used to analyze the data from interviews to determine common themes, patterns, similarities, and differences. Nine findings were discovered, including principals engage in PD focused on instructional leadership skills and perceive that PD has improved instructional practices and student outcomes, principals find value in networking and choice in PD, time is a barrier to participating in PD, and principal supervisors select and support principal PD opportunities. The findings provide principals, principal supervisors, and providers of principal PD with guidance on how to design PD focused on developing instructional leadership skills. Practitioners can utilize the study to guide the design of effective PD sessions that leverage the benefits noted by study participants while overcoming the challenges. Division leaders may consider the findings when developing PD plans for principals based on the literature and perceptions of study participants. These practices will help ensure principals receive the timely, targeted PD they need to become instructional leaders with a positive impact on student achievement. / Doctor of Education / Principals have an impact on the teaching and learning that takes place in their schools.

[toliau žr. visą tekstą] / Many various science areas are gradually relocating to information technology space and the recording of notes is not an exception. Hence, there are many different note recording and preserving formats and special software intended for the creation of such formats. However, because of comparatively rapid IT advancement it is usually hard to follow the all existing IT solutions and select the most proper, therefore, the objective of this work is to examine the technologies intended for the recording and preserving notes on the computer. During the time of this work the following examinations were completed: • The examination of note preserving formats; • The analysis of note recording software functionality; • The research of note recording software appeal; After completing the review of note preserving formats it was clear that they can be categorized into three groups: ascii, xml and binary. The note preserving formats which are based on ascii and xml codes are more coherent for the common user and take less hard disk space. After analyzing the note recording software the final results reveal that the Harmony Asisstant program is highly advanced and supports most functions. The Sibelius 6 is also very advanced and functional. After completing the note recording software appeal survey it was discovered that the respondents consider Sibelius 6 as the most appealing and coherent program.

A transferência e a divulgação de informações de interesse municipal / The transfer and dissemination of information of municipal interest

Mazini, Elisabeth Sardelli 17 August 2009 (has links)
Estudo sobre a transferência e a divulgação da informação no contexto dos serviços e sistemas de informação pública impulsionadas pela tecnologia. Explora, do ponto de vista teórico e prático, as interfaces estruturais, cognitivas e comunicativas que governam o processo de organização, o acesso e a transferência da informação, levando em consideração que informação é a representação de um conjunto documental que tem por finalidade a oferta e seleção de conteúdos independentemente dos suportes físicos que lhe dão materialidade. Nessa perspectiva, discute o conceito de informação, de documento e de mensagem, atentando também para os novos formatos digitais de transferência, com o intuito de verificar se funcionam como filtro perante a massa informativa disponível. Apoiando-se no referencial da Linguística Documentária, da Terminologia e da Linguística Textual, que postulam que a transferência de conteúdos semânticos para os segmentos usuários não é uma tarefa tributária da tecnologia, mas dependente da linguagem, dos propósitos da emissão, das características do público usuário e de seus conhecimentos prévios, são analisadas práticas informacionais da Fundação Prefeito Faria Lima Cepam. / This study is about information transference and divulging in the context of services and systems driven by technology in the environment of public information. Both from the theoretical and practical points of view, the study also seeks to explore the structural, cognitive and communicative interfaces which govern organizational processes as well as information access and transfer, taking into account that information is the representation of documentary collections, which aims to offer and select contents independently from physical media. From this stand point, the concepts of information, documentation and message are discussed, taking into consideration the new digital transference formats with the aim of checking whether they work as a filter for the available information mass. Another objective of this study is the analysis of informational practices of Fundação Prefeito Faria Lima Cepam supported by the references of Documentary Linguistics, Terminology and Textual Linguistics, which postulate that the transferring of semantic contents to the user is not a technological task, but one which depends on language, emission purposes, as well as on user characteristics and previous knowledge.

No. of bitstreams: 1 Vitor Curvelo Fontes Belém.pdf: 80820952 bytes, checksum: 8a7e262d42a4eb67ec50ba39ee3e8dee (MD5) Previous issue date: 2017-06-30 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES / In the midst of the transformations that mark the history of television in Brazil, the approximation between the borders of the environment and the cultural industries impel the emergence of new ways of producing, distributing and consuming television products. In this context, the tension between information and entertainment properties in television news is evident. The objective of this study is to analyze how this articulation is processed in the local television news, to understand how the genres, as forms of mediation, redefine and alter the configurations of the news. In this process, one questions how and why the news programs adopt the strategies of popular appeal, without decharacterizing them as a journalistic product or banalizing the understanding of the facts. For this, the concept of news is discussed and an update of the classification of its formats in the television is proposed. The perception of the strategy of the transformations in the television news is made from the observation of the corpus by seven categories of analysis proposed by the study. This bias will be analyzed in a comparative investigation between six editions of the television series "SETV 1st edition" and "SPTV 1st edition", presented in March 2017. From the qualitative research technique, it will be possible to better understand this phenomenon, considering the possible differences Between productions in their regional or national links. Thus, the study is not restricted to the analysis of the communicational technique, but also considers the relational processes, which involve the cultural dimensions of this approach. For this, the conceptual foundation of the research is based on theories of journalism, based on authors such as José Marques de Melo and Miguel Alsina, and on linguistic studies, with Mikhail Bakhtin and Lia Seixas. The theoretical framework is also based on cultural studies, with scholars such as Raymond Williams and Jesús Martín-Barbero, in order to understand the workings of television news, based on its link with culture and on the relation with infotenimento, conceptualized by Itania Gomes and Fábia Dejavite / Em meio às transformações que marcam a história da televisão no Brasil, a aproximação entre as fronteiras do meio e das indústrias culturais impulsionam o surgimento de novas formas de produzir, distribuir e consumir os produtos televisivos. Nesse contexto, evidencia-se o tensionamento entre as propriedades da informação e do entretenimento no telejornal. O objetivo desse estudo é analisar como se processa essa articulação nos noticiários televisivos locais, para compreender como os gêneros, enquanto formas de mediação, se redefinem e alteram as configurações da notícia. Nesse processo, questionase como e porque os telejornais adotam as estratégias de apelo popular, sem que os descaracterize como um produto jornalístico ou banalize a compreensão dos fatos. Para isso, discute-se o conceito de notícia e propõe-se uma atualização da classificação dos seus formatos na televisão. A percepção da estratégia das transformações no telejornal é realizada a partir da observação do corpus por sete categorias de análise propostas pelo estudo. Esse viés será analisado em uma investigação comparativa entre seis edições dos telejornais “SETV 1ª edição” e “SPTV 1ª edição”, exibidas em março de 2017. A partir da técnica de investigação qualitativa, será possível compreender melhor esse fenômeno, considerando as possíveis diferenças entre as produções em seus vínculos regionais ou nacionais. Assim, o estudo não se restringe à análise da técnica comunicacional, mas também considera os processos relacionais, que envolvem as dimensões culturais dessa aproximação. Para tanto, o fundamento conceitual da pesquisa parte das teorias do jornalismo, com base em autores como José Marques de Melo e Miguel Alsina, e dos estudos linguísticos, com Mikhail Bakhtin e Lia Seixas. O referencial teórico apoia-se também nos Estudos culturais, com estudiosos como Raymond Williams e Jesús Martín- Barbero, para compreender o funcionamento do telejornal, a partir da sua vinculação com a cultura e na relação com o infotenimento, conceituado por Itania Gomes e Fábia Dejavite

O cinema audiovisual: um formato configurado na interação teatro/cinema e TV

Luz, Inez Pereira da 14 May 2007 (has links)
Made available in DSpace on 2016-04-26T18:16:09Z (GMT). No. of bitstreams: 1 Ines P Luz.pdf: 2544958 bytes, checksum: 2ca05868a11fb4a8d4906a5c488841b1 (MD5) Previous issue date: 2007-05-14 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / The culture of the audiovisual has since 1980 been expanding as a circulating space for a set of old and new creative expressions. This movement promotes significant changes in the practices within the systems of signs and means, originating new formats whose compositions unveil the convergence of languages, regardless of the means which originate them and where they are inserted in. We start out from the hypothesis that the current Brazilian cinema is part of the audiovisual culture dynamics as a productive sphere where the hybridity of techniques and languages is predominant and, as a whole, the movement of feature films is not restricted to movie theater rooms, but rather flows through the space as a net, along with other audiovisual formats. The corpus of the research is formed by a few films made in Brazil between 1994/2004, resulting from the interaction cinema/TV and theater, and our objective was to survey the updating process of those expressions in their language compositions. Our method of analysis originates from the interlacing of the theories of I. Lotman (1996-1969), Jacques Aumont (2003, 2004), Noel Burch (1969), Gilles Deleuze (1990), M. McLuhan (1911-1980) and Umberto Eco (1987). Some of them point to languages as productions that are born from dialectical languages between the technical development and the cultural universe that shelters them, promoting the advances and ruptures of the systems of signs, from the aesthetics perspective and the knowledge production. Our research starts with some films shot by modern moviemakers, Orson Welles and Jean-Luc Godard, where we identify a thinking and a method on language interaction. We see how present they are in some contemporary formats created for the circulation in the TV medium. In the composition assessment of the film language of our corpus, we saw that they recreate the uniqueness of the systems of signs that originate them, mingling visual and audio references while the word is treated as a body where multiple expressions of literature, TV, comics, theater and songs are embedded. When making their sets visible, the films convey the creative process and one of the contemporary culture and thought perceptions, a writing that expands the dialogic thinking of cultural practices. The audiovisual formats configured by TV/cinema media to circulate in the network spaces bring in the pragmatic expression of the language, evidencing its extreme importance for the contemporary culture / A cultura do audiovisual desde 1980, tem se ampliado como espaço de circulação de um conjunto de expressões criativas antigas e novas. Esse movimento promove mudanças significativas nas práticas dentro dos sistemas de signos e meios, originando alguns formatos cujas composições revelam a convergência das linguagens, independente dos meios nos quais elas se originaram e estão inseridas. Partimos da hipótese de que o cinema brasileiro contemporâneo faz parte da dinâmica da cultura do audiovisual como uma esfera produtiva onde a hibridez de técnicas e linguagens é predominante, e no geral, o movimento dos filmes não se reduz às salas de cinema, mas passa pelo espaço em rede, junto com outros formatos audiovisuais. O corpus da pesquisa é constituído por alguns filmes produzidos no Brasil entre 1994/2004, resultados da interação cinema/TV e teatro e o nosso objetivo foi investigar o processo de atualização dessas expressões em suas composições de linguagens. O nosso método de análise tem origem no entrelaçamento de teorias de I. Lotman (1996-1969), Jacques Aumont (2003, 2004) Noel Burch (1969) Gilles Deleuze (1990), M. McLuhan (1980:220) e Umberto Eco (1987). Algumas delas apontam para as linguagens como produções que nascem das relações dialéticas entre o desenvolvimento técnico e o universo cultural que as abriga, promovendo os avanços e rupturas dos sistemas de signos, do ponto de vista estético e de produção de conhecimento. Nossa investigação tem início com alguns filmes dos cineastas modernos, Orson Welles e Jean-Luc Godard, onde localizamos um pensamento e um método sobre a interação de linguagens. Vimos como eles se encontram presentes em alguns formatos contemporâneos criados para circulação no médium TV. Na análise da composição das linguagens dos filmes do nosso corpus, vimos que elas recriam as singularidades dos sistemas de signos que lhes deram origem, misturam referências visuais e de áudio, e a palavra é tratada como um corpo onde se encontram embutidas várias expressões: literatura, TV, história em quadrinhos, teatro e canção. Ao fazer visível o conjunto delas, os filmes comunicam o processo criativo e uma das percepções e pensamento da cultura contemporânea, uma escritura que amplia o pensar dialógico das práticas culturais. Os formatos audiovisuais, configurados pelas mídias TV/cinema para circular nos espaços das redes, trazem a dimensão pragmática da linguagem, evidenciando a sua extrema relevância na cultura contempo

Interopérabilité des environnements virtuels 3D : modèle de réconciliation des contenus et des composants logiciels

Bouville, Rozenn 20 December 2012 (has links) (PDF)
Les environnements virtuels 3D sont aujourd'hui utilisés dans de nombreux domaines et couvrent de multiples usages qui vont du divertissement à l'apprentissage en passant par la conception pour l'industrie. Si leur nombre ne cesse de croître chaque année, un problème récurrent freine leur adoption et leur diffusion. Il est en effet aujourd'hui très difficile d'importer des données dans un environnement virtuel autre que celui pour lequel ces données ont été créées. Ceci entraîne de nombreux autres problèmes qui ralentissent la création d'environnements virtuels 3D, augmente leur coût de production et limite leur accès aux utilisateurs. Nous présentons ici une solution qui se propose de réconcilier les modèles existants et à venir de façon à rendre interopérables les contenus et les composants logiciels des environnements virtuels 3D. Cette solution repose sur deux éléments complémentaires: une architecture logicielle et un modèle de conteneur de formats 3D. Nous avons appelé notre système l'adaptateur de graphes de scène ou SGA. Il s'agit d'une architecture générique et modulaire qui permet le chargement de plusieurs formats 3D dans la plupart des composants logiciels des environnements virtuels 3D. Le SGA a non seulement pour rôle d'adapter tous les graphes de scène encodés dans les fichiers 3D en graphes de scène pour les composants qui sont utilisés par l'environnement virtuel mais également de gérer la synchronisation de ces graphes de scène au cours du déroulement de l'application de l'environnement virtuel. Nous avons réalisé une implémentation de cette architecture ainsi que plusieurs instanciations qui permettent le chargement de fichiers au format X3D et COLLADA dans une application dont le rendu se base sur le moteur de rendu graphique Ogre3D et le moteur physique Bullet. Ceci nous a permis de démontrer la faisabilité de cette solution et d'évaluer ses performances. Notre modèle de conteneur de formats 3D permet non seulement de composer des scènes faites à partir des plusieurs fichiers 3D mais aussi de combiner leurs fonctionnalités et de les faire interagir dans l'environnement virtuel. Ce modèle est appelé 3DFC pour conteneur de fichiers 3D et il repose sur le système du SGA pour l'adaptation des graphes de scène encapsulés dans les fichiers référencés par le conteneur. Nous avons réalisé une instanciation pour le modèle 3DFC que nous avons intégrée à notre implémentation du SGA. Nous avons ainsi pu mixer dans une même scène des modèles X3D et COLLADA et combiner les fonctionnalités d'interactions offertes par X3D avec les propriétés physiques autorisées dans COLLADA.
