Academic literature on the topic 'Multilinearity'

This paper addresses three paradigms in epistemological structures that could serve as preliminary classifications enabling a systematic approach to past and current media phenomena such as hypertext, diagrams and ubiquitous computing. Nonlinearity is discussed by Vilém Flusser in the context of "technical images." In his own approach to go beyond linear text, Flusser and his publisher created a digital version of his book Die Schrift on a floppy disk (1987), enabling the reader to jump between chapters or to rewrite the text. Multilinearity is a concept that is revived within the diagrammatology discourse, transcending linearity through topographical ways of reading. Current examples can be found in arts and narratives such as Chris Ware's comics, who uses diagrammatics to blur the lines between the reader and the author. Simultaneity as a technological attribute is essential to current ubiquitous and pervasive technologies and services and draws heavily on Heideggerian concepts such as readiness-to-hand and background. In this epistemological shift, the information is instantaneously organized according to the user's needs. Each of these epistemological structures offers a different idea about receiving and creating knowledge, information and communication, paving the way for narrative and media strategies that are more and more determined by a 'reader' becoming a 'user' and a 'text' becoming a 'service.'

A robust scheme to estimate a set of models for a linear time-invariant system, subject to perturbations in the physical parameters, from a frequency response data record is proposed. The true model as well as the disturbances affecting the system are assumed unknown. However, the physical parameters are assumed to enter the coefficients of the system transfer function multilinearly. A set of models is identified by perturbing the physical parameters one-at-time and using a frequency domain identification technique. Exploiting the assumed multilinearity, the estimated set of models is validated. The proposed scheme is evaluated on a number of simulated systems, and on a physical robot manipulator arm.

The notion of a tensor captures three great ideas: equivariance, multilinearity, separability. But trying to be three things at once makes the notion difficult to understand. We will explain tensors in an accessible and elementary way through the lens of linear algebra and numerical linear algebra, elucidated with examples from computational and applied mathematics.

Tendo em vista as formas de interação entre os sujeitos e os audiovisuais ficcionais interativos, esta pesquisa teve como objetivo geral a elaboração de diretrizes para a criação de roteiro cinematográfico ficcional multilinear interativo com base na potencialização da experiência estética do espectador. Com o avanço dos aparatos tecnológicos e as inovadoras possibilidades, o iCinema (cinema interativo) ganha maior força e conquista os espectadores quanto à imersão e à participação no processo de decisão da trajetória da história. A partir disso, foram traçados alguns objetivos específicos teóricos: estudar a experiência estética gerada na recepção da narrativa cinematográfica; compreender o fluxo motivacional e o papel dos dispositivos na construção da mise-én-scène; verificar as etapas da construção de um roteiro cinematográfico clássico e a possibilidade de construção multilinear; e explorar métodos multimetodológicos para a pesquisa. Com relação aos objetivos específicos práticos, buscou-se: co-produzir um roteiro de curta-metragem cinematográfico ficcional interativo; realizar um estudo de recepção com profissionais da área audiovisual a partir do roteiro criado; entender a relação dos espectadores com narrativas multilineares e interativas; entender os dispositivos cinematográficos com vistas a potencializá-los na criação do roteiro; e criar diretrizes para a elaboração de roteiros interativos. O crescimento das possibilidades criadas pelos filmes pode ser percebido na ampliação das narrativas fílmicas e nos diversos movimentos propiciados por esta mídia, gerando múltiplas sensações e a intensificação das emoções. Neste contexto, buscou-se responder à seguinte pergunta de pesquisa: como construir uma narrativa cinematográfica ficcional multilinear a partir de dispositivos cinematográficos contemporâneos, fazendo com que o espectador vivencie uma experiência extraordinária? Para responder aos objetivos da pesquisa traçou-se um plano multimetodológico (BAUER, GASKELL, 2008), compreendendo abordagens qualitativa, quantitativa, pesquisas bibliográficas, documentais e empíricas (MERRIAM, 1998; MERKLE, 2000). A abordagem junto aos espectadores teve a participação de 24 pessoas, homens e mulheres, entre 20 e 39 anos, fluentes em internet e novas mídias. O roteiro de curta-metragem cinematográfico multilinear interativo foi criado por Raul Inácio Busarello e Patricia Bieging. O estudo de recepção (JACKS; ESCOSTEGUY, 2005) teve a participação de sete especialistas em produção audiovisual. Verificou-se que a multilinearidade das estruturas colabora com o iCinema e convida o espectador, que espera ser surpreendido, a assumir papéis importantes para o desenvolvimento da narrativa. Evidenciou-se que o gerenciamento da interatividade é o ponto chave do iCinema e um desafio para os roteiristas e para os produtores. Estas desafiadoras experiências permitem maior interação e, até mesmo, imersão e profunda vivência dos sujeitos frente à narrativa. Possibilita, inclusive, a interferência em seu fluxo narrativo, fazendo com que a obra seja reformulada de acordo com as escolhas do espectador. Em resposta à pergunta de pesquisa foram elaborados quatro grupos de diretrizes, que se subdividem, visando à criação de roteiros cinematográficos multilineares interativos, sendo: 1) foco nas estratégias de potencialização da experiência do espectador, subdividido em: criação da narrativa, captura da atenção, realismo da narrativa, personagens e self-experience; 2) dispositivos estratégicos e gerenciamento interativo; 3) gerenciamento das ramificações, subdividido em: manutenção do fluxo, teasers e inatividade do espectador; 4) condução do fluxo narrativo.
Considering the forms of interaction between subjects and interactive fictional audiovisual means, this study aimed at elaborating guidelines to create an interactive multilinear fictional movie script based on boosting spectators\' aesthetic experience. With the advances in technologies and the innovative possibilities they ensue, iCinema has been gaining momentum and conquering spectators as to its immersion and participation in decision-making processes for the plot. From this scenario, specific theoretical objectives were also outlined: to study the aesthetic experience generated from the reception of a movie narrative; to understand motivational flow and the role of devices in building the mise-én-scène; to verify the stages in a classic movie script writing and possibilities for multilinear writing; and to explore multi-methodological methods for the study. Specific practical objectives included: to co-produce an interactive fictional short film script; to study its reception with audiovisual professionals; to understand the relation between spectators and interactive multilinear narratives; to understand the cinema devices and boost their functions in script writing; and to create guidelines to write interactive scripts. The increasing possibilities created by film can be perceived by the broadening of film narratives, and by several movements enabled by such medium, thus generating a multitude of sensations and intensified emotions. In this context, the research question guiding this study was: how can one build a multilinear fictional filmic narrative from contemporary cinema devices in order that spectators have an extraordinary experience? In order to fulfill the objectives of this study, a comprehensive multi-method plan (BAUER, GASKELL, 2008) was devised to approach qualitative, quantitative, bibliographic, documental, and empirical aspects of research (MERRIAM, 1998; MERKLE, 2000). Spectator approach involved 24 participants, men and women with ages between 20-39 that were literate in new media and the Internet. The interactive multilinear short film script was written by Raul Inácio Busarello and Patricia Bieging. The reception study (JACKS; ESCOSTEGUY, 2005) was performed with 7 audiovisual production specialists. It was possible to verify that structural multilinearity collaborates with iCinema and invites spectators, who expect surprises, to take on important roles to develop the plot. It was evident that managing interactivity is the key point in iCinema, and it poses a challenge for screenwriters and producers alike. These challenging experiences allow for greater interaction, and even immersion and profound dedication of subjects to the narrative. It even allows for interference in narrative flow, enabling reformulation of the film according to spectator choices. In response to the research question, 4 groups of guidelines were elaborated and subdivided for the creation of interactive multilinear screenplays, namely: 1) focus on spectator experience boost strategies: narrative creation, attention capture, narrative realism, characters, and self-experience; 2) strategic devices and interactive management; 3) branch management: flow maintenance, teasers, and spectator inactivity; and 4) narrative flow and pacing.
