scientific visualization

Using the computer to display real-world objects that cannot normally be seen, such as the shapes of molecules, air and fluid dynamics and weather patterns. Scientific visualization requires enormous computing resources, and the supercomputer centers and national laboratories throughout the world are always at the forefront of such activity. See visualization.


Visualizing the Structure of Protein
The picture on the left is the x-ray diffraction pattern of an apilopoprotein E3 protein crystal, which plays a major role in cholesterol metabolism. The tiny spots are the x-ray reflections from the crystal, which are used to reconstruct the electron density of atoms (right).






Next Stage - The Structure Model
The colored sticks are the detailed 3-dimensional structure models of the molecule that were fitted into the actual electron density (blue grid-like areas). This stereo image appears 3D when viewed cross-eyed.






The Final Ribbon Model
Using visualization techniques, the overall 3D four-helix bundle structure of the molecule is represented as a ribbon model. The 3D image of this molecule helps researchers better understand it and its interaction with other molecules.

A analise de conteudo configura-se como importante ferramenta de investigacao que permite aos pesquisadores analisar unidades informativas de textos em termos de suas qualidades simbolicas e papeis comunicativos, mostrando-se apropriada para estudo de infograficos, particularmente os que denominamos infovis (1).
A modalidade infovis, no contexto do presente artigo, designa um produto midiatico do jornalismo on-line que se caracteriza por ser, simultaneamente:
Com o objetivo de tracar um panorama sobre estado da arte e tendancias de utilizacao da infografia interativa com base em dados, aplicamos o modelo de Krippendorff (2004: 86) na analise de um corpus de 270 infovis relativos a temas politicos, publicados entre janeiro de 2010 e dezembro de 2013 (periodo com, pelo menos, uma eleicao presidencial no pais sede da publicacao), em quatro sites jornalisticos: The New York Times, The Guardian, Folha de S.
O infovis, como dispositivo interacional (braga, 2011), pode ser compreendido como um sistema comunicacional pelo qual conteudos sao tecnologicamente produzidos e apresentados por comunicadores, de um lado, e explorados, de outro, por meio de recursos interativos disponiveis aos usuarios, de modo que a integracao entre estes dois agentes--comunicadores e usuarios--se da pela mediacao do design visual e do tratamento jornalistico da informacao, no espaco que convencionamos chamar de interface do dispositivo (Figura 1).
