Estimating Volumes of Near-spherical Molded Artifacts

May 3, 2010
Author(s)
David E. Gilsinn, Bruce R. Borchardt, Amelia Tebbe
The Food and Drug Administration (FDA) is conducting research on developing reference lung cancer cancer lesions, called phantoms, to test computed tomography (CT) scanners and their software. FDA loaned two semi-spherical phantoms to the National

TOWARDS INDUSTRIAL IMPLEMENTATION OF EMERGING SEMANTIC TECHNOLOGIES

August 31, 2011
Author(s)
Paul W. Witherell
In this paper, we identify five main obstacles in the development of an industry-ready application of semantic knowledge management systems and discuss how each of these challenges can be addressed. These obstacles include the ease of new knowledge

Virtual Assembly Design Environment

September 1, 1995

Modeling the Microstructure and Elastic Properties of Complex Materials

May 1, 2000
Author(s)
A P. Roberts, Edward Garboczi
This document is derived from three reviewed papers by the same authors: (1)Elastic properties of a tungsten-silver composite by reconstruction and computation; (2)Elastic properties of model porous ceramics; and (3)Elastic properties of model random three

A Lexical Analogy to Feature Matching and Pose Estimation

January 1, 2002
Author(s)
John A. Horst
We relate the problem of finding a correspondence between sensed and model features to that of finding a match between a random set of letters and words in a dictionary. The process is equivalent to hashing and the linguistic perspective is added to

A Shape Modeling Application Program Interface (API) for the STEP Standard

November 1, 2000
Author(s)
Mike Pratt, B D. Anderson
The international standard ISO 10303 for the exchange of product models and associated data between different computer aided design (CAD) and other engineering systems was first issued in 1994. This paper reports on current work on extending the standard

Air-Side Velocity Distribution in Finned-Tube Heat Exchangers

December 17, 2007
Author(s)
David A. Yashar, Hong H. Cho
The performance of finned tube heat exchangers is greatly affected by the distribution of the air that passes through it. The air side velocity distribution is largely left unknown because it is difficult to measure accurately. In this study, we examined
