shapeSift: Suggesting sustainable options in design reuse from part repositories

Devarajan Ramanujan, William Benjamin, William Z. Benstein, Niklas Elmqvist, Karthik Ramani
ASME IDETC/CIE 2013

shapeSift is a framework for supporting sustainability based decision making during selection of similar previous designs from part repositories. Our framework is designed for 3D part repositories that contain metadata pertaining to materials and...

Understanding Brainstorming through Text Visualization

Understanding Brainstorming through Text Visualization

Senthil Chandrasegaran, Lorraine Kisselburgh, Karthik Ramani
ASME IDETC/CIE 2013

Automated content analysis software tools have significantly aided in the study of design processes in the recent past. However, they suffer from the lack of domain knowledge and insight that a human expert can provide. In this paper, we adopt the...

Multiscale Kernels using Random Walks

Karthik Ramani, Ayan Sinha
11th Symposium on Geometry processing, 3-5 July, Genova, Italy, 2013. Proceedings of the Computer Graphics Forum, Computer Graphics Forum, Volume 33, Issue 1, pages 164–177, 2014.

ABSTRACT We introduce novel multiscale kernels using the random walk framework and derive corresponding embeddings and pairwise distances. The fractional moments of the rate of continuous time random walk (equivalently diffusion rate) are used to...

Computer-Aided Design, Volume 45, Issue 2, February 2013, Pages 277-287, ISSN 0010-4485, 10.1016/j.cad.2012.10.011. (http://www.sciencedirect.com/science/article/pii/S0010448512002163)

Abstract: We present a novel interaction system, “Shape-It-Up”, for creative expression of 3D shapes through the naturalistic integration of human hand gestures with a modeling scheme dubbed intelligent generalized cylinders (IGC). To...

The evolution, challenges, and future of knowledge representation in product design systems

The evolution, challenges, and future of knowledge representation in product design systems

Senthil Chandrasegaran, Karthik Ramani, Ram D. Sriram, Imre Horvath, Alain Bernard, Ramy Harik, Wei Gao
Computer-Aided Design Volume 45, Issue 2, February 2013, Pages 204-228.

Abstract: Product design is a highly involved, often ill-defined, complex and iterative process, and the needs and specifications of the required artifact get more refined only as the design process moves toward its goal. An eff ective computer...
