Evaluating CT for Metrology: The Influence of Material Thickness on Measurements

October 7, 2014
Author(s)
Joseph Schlecht, Eric Ferley, Shaun COUGHLIN , Steven D. Phillips, Vincent Lee, Craig M. Shakarji
X-ray imaging provides a non-destructive means to measure internal features of a workpiece, and CT offers unique capabilities for internal measurements in 3-D. However, due to the computational nature of CT and its indirect measurement process, assessing

Practical CFD Simulations of Wind Tunnel Tests

December 1, 2013
Author(s)
Dilip K. Banerjee, Scott Hemley, Randall J. McDermott, Donghun Yeo, Marc L. Levitan
Computational fluid dynamics (CFD) has the potential of replacing wind tunnel testing in many wind engineering applications. Validated CFD software could enable structural engineers and builders to calculate wind effects on buildings for which no

The DEMO Quasisymmetric Stellarator

February 26, 2010
Author(s)
Paul R. Garabedian, Geoffrey B. McFadden
The NSTAB code solves differential equations in conservation form, and the TRAN test particle code tracks guiding center orbits in a fixed background, to provide simulations of equilibrium, stability, and transport in tokamaks and stellarators. These codes

Estimating Volumes of Simulated Lung Cancer Nodules

July 15, 2009
Author(s)
David E. Gilsinn, Bruce R. Borchardt, Amelia Tebbe
Lung cancer is a disease of uncontrolled cell growth in tissues of the lung. Computed tomography (CT) shows promise in detecting lung cancers at earlier, more operable stages, when survival is better. CT scans generate multiple 2-D slice images of the lung
