Short for Hexahedra from Unique Location in (K)convex Polyhedra – HULK is a simple and efficient algorithm to generate hexahedral meshes from generic STL files describing a geological model to be used in simulation tools based on the finite difference, finite volume or finite element methods. Using binary space partitioning of the input geometry and octree refinement on the grid, a successive i...

in this paper, we deal with the subdierential concept onhadamard spaces. flat hadamard spaces are characterized, and nec-essary and sucient conditions are presented to prove that the subdif-ferential set in hadamard spaces is nonempty. proximal subdierentialin hadamard spaces is addressed and some basic properties are high-lighted. finally, a density theorem for subdierential set is establi...

The new SOCRATES (ShOrtening CRiteria and ATtributES) method for reducing the dimensionality of attribute space is described. In this method, a large number initial numerical and/or verbal characteristics objects are aggregated into single integral index or several composite indicators with small scales qualitative estimates. Multiattribute represented as multisets object properties. aggregatio...
