An Evaluation of Local Shape Descriptors for 3D Shape Retrieval

March 8, 2012
Author(s)
Sarah Y. Tang
As the usage of 3D models increases, so does the importance of developing accurate 3D shape retrieval algorithms. Most prominently, shape descriptors are used to describe the geometric and topological properties of objects and compared to determine two

Modeling of the Temperature Field in the Chip and in the Tool in High-speed Machining of a Carbon Steel: Effect of Pearlite to Austenite Phase Transition in AISI 1075

April 7, 2010
Author(s)
Timothy J. Burns, Steven P. Mates, Richard L. Rhorer, Eric P. Whitenton, Debasis Basak, Russell H. McFadden
A one-dimensional transient finite-difference model for the temperature distribution in orthogonal metal cutting, which was originally developed by Boothroyd, and then improved upon by Tlusty, is used to calculate the temperature field in the chip and in

A DATA FLOW IMPLEMENTATION OF AGENT-BASED DISTRIBUTED GRAPH SEARCH

November 4, 2009
Author(s)
Imad Hamchi, Mathieu Hoarau, Antoine Fillinger, Nicolas Crouzier, Lukas Diduch, Martial Michel, Vincent M. Stanford
Biological ants organize themselves into forager groups that converge to shortest paths to and from food sources. This has motivated development a large class of biologically inspired agent-based graph search techniques, called Ant Colony Optimization, to

Matching Observed Alpha Helix Lengths to Predicted Secondary Structure

November 1, 2009
Author(s)
Brian D. Cloteaux, Nadezhda Serova
Because of the complexity in determining the 3D structure of a protein, the use of partial information determined from experimental techniques can greatly reduce the overall computational expense. We investigate the problem of matching experimentally

Semantic Web for Chemical Genomics: Need, How To, And Hurdles

July 19, 2006
Author(s)
Talapady N. Bhat
Semantic Web has been often suggested as the information technology solution to the growing problem in managing the millions of data points generated by modern science such as nanotechnology and high through-put screening for drugs. However, the progress
