Volume-Preserving Free-Form Solids
Some important trends in geometric modeling are the reliance on solid models rather than surface-based models and the enhancement of the expressive power of models, by using free-form objects in addition to the usual geometric primitives and by incorporating physical principles. An additional trend is the emphasis on interactive performance. In this paper we integrate all of these requirements ...
متن کاملRole of Free Volume in Polymer Solution Thermodynamics
The principal effects determining the value of the free energy of mixing of polymer solutions are discussed and compared, namely the combinatorial, energetic and structural effects. The influence of the last on the thermodynamic behaviour of polymer solutions is then dealt with, as revealed in the lower critical solution temperature. and in the effect of pressure on polymer—solvent compatibilit...
متن کاملDiffusion in Polymer Solids and Solutions
The industrial importance of penetrable and/or impenetrable polymer systems is evident when one faces with a huge number of publications considering various aspects of diffusion phenomenon. Strong worldwide interest to realize more details about the fundamental of the process, generalize the governed laws to new findings, and find fast and reliable techniques of measurement, makes motivation to...
متن کاملDiscriminating the volume of motion-defined solids.
We investigated the ability of human observers to discriminate an important global 3-D structural property, namely volume, of motion-defined objects. We used convex transparent wire-frame objects consisting of about 12 planar triangular facets. Two objects, vertically separated by 7 degrees, were shown simultaneously on a computer display. Both revolved at 67 degrees/sec around a common vertica...
متن کاملQuantitative relations between cooperative motion, emergent elasticity, and free volume in model glass-forming polymer materials.
The study of glass formation is largely framed by semiempirical models that emphasize the importance of progressively growing cooperative motion accompanying the drop in fluid configurational entropy, emergent elasticity, or the vanishing of accessible free volume available for molecular motion in cooled liquids. We investigate the extent to which these descriptions are related through computat...
