  1. Recensão a Jacques Rancière, os intervalos do cinema

    Soares, Ana Isabel
    (Quando li pela primeira vez um ensaio de Jacques Rancière, lembro-me, pensei em Sebastião da Gama. Não é tão distante o tiro: a ideia de saber, em Gama, é a ideia daquilo que procura o mestre desconhecedor. Mas talvez o que mais tivesse aproximado aquelas duas figuras, na minha leitura, fosse um certo posicionamento, de ambos, perante o que pretendem conhecer. As explorações da sala, de cada um dos rostos dos seus alunos, fazem de Gama o “incapaz como tal” que constitui o explicador no relato sobre a “aventura intelectual” de Joseph Jacotot, tal como Rancière a narrou no começo...

  2. Tempo e conceitos em Hans Ulrich Gumbrecht

    Soares, Ana Isabel
    Entre as páginas do exemplar de Produção de Presença que tenho comigo, guardo duas folhas, com impressões a cores de outros tantos artigos que Hans Gumbrecht publicou n’O Estado de São Paulo, em fevereiro e em março de 2009. Um debruça-se sobre “A crise de um futebol sem rosto”, título que discute a fraca prestação da seleção canarinha nos jogos de preparação para o Mundial de 2010; no outro artigo, anterior àquele, em pouco mais de três colunas, traça-se o quadro de uma cultura desaparecida: o ideal comunista de Leon Trotsky.

  3. Cinema português/cinema literário?

    Soares, Ana Isabel
    Antes de refletir sobre o carácter adjetival presente no segundo termo do título, sugiro que se pense em como os nomes “literatura” e “cinema” frequentemente integram expressões mediadas por uma conjunção ou por locuções preposicionais: Literatura e Cinema, Cinema na Literatura, O Cinema da Literatura, enfim, a série de possíveis combinações e as adjetivações possíveis que, pela proximidade dos termos, delas deriva. Qualificar “cinema” como “literário” implica, desde logo, um entendimento (em separado) daquilo que é fílmico e daquilo que é literário. Só então se torna possível teorizar uma eventual relação entre ambos, uma expressão que sugira, do começo, a...

    O filme Nha fala (2002), uma comédia-musical, do cineasta Flora Gomes, narra parte da história de Vita, uma jovem guineense, que carrega uma maldição familiar, que proíbe que as mulheres de sua família cantem e, caso essa lei seja descumprida, elas morrerão. No entanto, ao viajar para estudar na França e apaixonar-se por Pierre, canta, conhece o sucesso e resolve voltar para a Guiné-Bissau, para realizar o seu próprio funeral. O presente ensaio, centra-se na análise do filme Nha fala, enfocando inicialmente na discussão sobre gêneros cinematográficos e depois na musicalidade africana e, em especial, as músicas que compõem o...

  5. Stress approach by media art

    Figueiredo, Mauro; Jesus, Saul; Duarte, Duarte; Cabral, Fernando
    With a background in conceptual art and media art, and the relations between science and art, we tried to approach the concept of stress through art. Stress is a recent problem of people in several countries, and could be caused by external factors, such as social pressure, or be derived from internal factors, such as the requirement that the subject puts himself. Stress had a negative impact at several organs of the human body, but heart is the main one. Taking into account all of these aspects, and from photos of two drawings of the heart ?????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????? setup program EDIUS, that integrate...

  8. A topological framework for interactive queries on 3D models in the web

    Figueiredo, Mauro; Rodrigues, J. I.; Silvestre, Ivo; Veiga-Pires, C.
    Several technologies exist to create 3D content for the web. With X3D, WebGL, and X3DOM, it is possible to visualize and interact with 3D models in a web browser. Frequently, three-dimensional objects are stored using the X3D file format for the web. However, there is no explicit topological information, which makes it difficult to design fast algorithms for applications that require adjacency and incidence data. This paper presents a new open source toolkit TopTri (Topological model for Triangle meshes) for Web3D servers that builds the topological model for triangular meshes of manifold or nonmanifold models. Web3D client applications using this...

  9. Surface collision detection for virtual prototyping

    Figueiredo, Mauro
    This paper presents an efficient collision detection algorithm designed to support assembly and maintenance simulation of complex assemblies. This approach exploits the surface knowledge, available from CAD models, to determine intersecting surfaces. It proposes a novel combination of Overlapping Axis-Aligned Bounding Box (OAABB) and R-tree structures to gain considerable performance improvements. This paper also shows an efficient traversal algorithm based on the R-tree structure of Axis-Aligned Bounding Boxes to determine intersecting objects and intersecting surfaces between three-dimensional components, for supporting the recognition of constraints in assembly and disassembly operations in virtual prototyping environments. The implementation of the proposed collision detection algorithm...

  13. The development of an interactive mathematics app for mobile learning

    Figueiredo, Mauro; Godejord, Beata; Rodrigues, José
    Low achievement in mathematics education has been an increasing problem in the recent years in some countries. According to a 2010 study from the U.S. Department of Education, blended learning classes produce statistically better results than their face-to-face. There is also an increasing number of students using smartphones and tablets in schools. Mobile devices gained popularity as an educational tool and there are many schools that use them frequently in educational activities to improve learning. In this paper, we present the development of an application for smartphones and tablets to provide activities that students can do outside the classroom or...

  17. High-resolution digital 3D models of Algar do Penico Chamber: limitations, challenges, and potential

    Silvestre, Ivo; Rodrigues, José; Figueiredo, Mauro; Veiga-Pires, C.
    The study of karst and its geomorphological structures is important for understanding the relationships between hydrology and climate over geological time. In that context, we conducted a terrestrial laser-scan survey to map geomorphological structures in the karst cave of Algar do Penico in southern Portugal. The point cloud data set obtained was used to generate 3D meshes with different levels of detail, allowing the limitations of mapping capabilities to be explored. In addition to cave mapping, the study focuses on 3D-mesh analysis, including the development of two algorithms for determination of stalactite extremities and contour lines, and on the interactive...
