Abstract: Background: Many molecules of interest are flexible and undergo significant shape deformation as part of their function, but most existing methods of molecular shape comparison (MSC) treat them as rigid bodies, which may lead to...

Towards Beautification of Freehand Sketches using Suggestions
SBIM '09: Proceedings of the 6th Eurographics Symposium on Sketch-Based Interfaces and Modeling, New Orleans, Louisiana, 2009, pp 69-76
Abstract: Beautification of freehand sketches is integral for building robust sketch understanding systems and sketch-based inter-faces for CAD. Many of the current methods for beautification do not consider some important information implied in...
Robust principal axes determination for point-based shapes using least median of squares
Published in Computer-Aided Design, 2009; 41(4): 293-305
Abstract:A robust technique for determining the principal axes of a 3D shape represented by a point set, possibly with noise, is presented. We use techniques from robust statistics to guide the classical principal component analysis (PCA)...
Developing Engineering Ontology for Information Retrieval
Journal of Artificial Intelligence for Engineering Design, Analysis and Manufacturing 8, 011003 (2008)
Abstract: When engineering content is created and applied during the product life cycle, it is often stored and forgotten. Current information retrieval approaches based on statistical methods and keyword matching are not effective in understanding...
