Consideration is given to the techniques required to support adaptive analysis of automatically generated unstruc-tured meshes on distributed memory MIMD parallel computers. The key areas of new development are focused on the support of effective parallel computations when the structure of the numerical discretization, the mesh, is evolving, and in fact(More)
This paper presents the requirements for a surface mesh to be valid. Aside from validity, it also discusses conditions for geometric similarity, which quantitatively describes how the surface mesh " matches " the model geometry. The surface mesh generation method presented here uses the parameter space of a model face to generate a coarse triangulation. In(More)
Consideration is given to the techniques required to support adaptive analysis of automatically generated unstructured meshes on distributed memory MIMD parallel computers. Emphasis is placed on the structures needed to support effective parallel computations when the numerical discretization, the mesh, is defined and evolves during the computation. The key(More)
We administered the Set Test to 128 control subjects and 82 patients with Alzheimer's disease. The subjects were to produce, within 15 seconds, items within specific categories: colors, animals, fruits and cities. Control subjects obtained a mean score of 40.3 +/- 3.6 and Alzheimer's disease patients a mean score of 2.7 +/- 4. We found a significant effect(More)
