Virtual Repair: Geometric Reconstruction for Remanufacturing Gas Turbine Blades

by preciseadmin | Aug 14, 2011 | 2011, Cecil Piya, HUMAN SHAPE INTERACTION, Karthik Ramani, Publications, Shape Understanding

Abstract: The usage of Direct Metal Deposition (DMD) technology for repairing defective voids in high-value metallic components is time consuming, since traditional geometric reconstruction methods are not seamlessly connected to the DMD process. Here, we consider the...

Towards Enabling Visual Design Exploration Involving Multiple Abstractions of Design Descriptions

by preciseadmin | Aug 10, 2011 | 2011, DESIGN METHOD, Design Representation, Karthik Ramani, Publications

Abstract: Designers use several visual tools for exploring and understanding design problems and solutions. House of Quality (HoQ), function-structure, Morphological matrices, concept selection tables, 2D drawings are some of the visual tools and representations used...

Sketching Workshop for College Mentors for Kids

by Joran | May 19, 2011 | Joran Booth, Outreach

In 2011, we were asked to teach kids about what it means to be an engineer and have some engineering activity.  We talked to the kids about what engineers are and how they use sketching to do their work.  They loved...

sLLE: Spherical Locally Linear Embedding with Applications to Tomography

by _not_Exist_ | May 15, 2011 | 2011, HUMAN SHAPE INTERACTION, Karthik Ramani, Publications, Shape Understanding

Abstract: The tomographic reconstruction of a planar object from its projections taken at random unknown view angles is a problem that occurs often in medical imaging. Therefore, there is a need to robustly estimate the view angles given random observations of the...

Temperature Distribution Descriptor for Robust 3D Shape Retrieval

by preciseadmin | May 14, 2011 | 2011, HUMAN SHAPE INTERACTION, Karthik Ramani, Publications, Shape Understanding

Abstract: Recent developments in acquisition techniques are resulting in a very rapid growth of the number of available three dimensional (3D) models across areas as diverse as engineering, medicine and biology. It is therefore of great interest to develop the...
