Computing global visibility maps for regions on the boundaries of polyhedra using Minkowski sums

by _not_Exist_ | Sep 16, 2009 | 2009, HUMAN SHAPE INTERACTION, Karthik Ramani, Shape Understanding

Abstract A global visibility map is a spherical image built to describe the complete set of global visible view directions for a surface. In this paper, we consider the computation of global visibility maps for regions on the boundary of a polyhedron. Both the...

Three dimensional shape comparison of flexible protein using the local-diameter descriptor

by _not_Exist_ | Sep 16, 2009 | 2009, HUMAN SHAPE INTERACTION, Karthik Ramani, Shape Understanding

Abstract: Background: Techniques for inferring the functions of the protein by comparing their shape similarity have been receiving a lot of attention. Proteins are functional units and their shape flexibility occupies an essential role in various biological...

A method for measuring part similarity using ontology and a multi-criteria decision making method

by _not_Exist_ | Sep 16, 2009 | 2009, DESIGN METHOD, Design Representation, Karthik Ramani

Abstract: When existing parts are re-used for the development of a new product or business-to-business transactions, a method for searching parts from a part database that is similar to the user’s requirements is necessary. To this end, it is important to...

Port-based Ontology Semantic Similarities for Module Concept Creation

by _not_Exist_ | Sep 16, 2009 | 2009, DESIGN METHOD, Design Representation, Karthik Ramani

Abstract: The modularity indicates a one-to-one mapping between functional concepts and physical components. It can allow us to generate more product varietiesat lower costs. Functional concepts can be described by precise syntactic structures with functional...
