Assessing the Quality of Visualizations Produced Using Volume Rendering: Experi...
Beatriz Sousa Santos; José Nunes; Carlos Coimbra; Carlos Ferreira; Ana Maria Tomé; Nuno LauA set of parameters to assess the objective quality of visualizations of a voxel based data set, produced using a ray caster, is proposed as a first step toward the evaluation of the overall quality of these visualizations.Results obtained using synthetic data and a simple implementation of a ray caster are presented. The final goal of this evaluation will be the computation of “c...
Sorption and diffusion of dense carbon dioxide in a biocompatible polymer
Duarte, Ana Rita C.; Martins, Carlos; Coimbra, Patrícia; Gil, Maria H. M.; Sousa, Hermínio C. de; Duarte, Catarina M. M.Mass sorption and diffusion coefficients in one acrylate biocompatible copolymer contacted with supercritical (sc) carbon dioxide are reported. Equilibrium solubility of dense carbon dioxide in poly(methylmethacrylate-co-ethylhexylacrylate-co-ethyleneglycoldimethacrylate) (P(MMA-EHA-EGDMA)) was studied by a gravimetric method in a temperature range from 308 to 323 K and a pressure range from 10.0 to 20.0 MPa.
