Color Issues of White LEDs

Author(s)
Yoshihiro Ohno
For white LEDs to be used for general lighting, they should have appropriate white color and good color rendering performance for illuminated objects. Color

Field Demonstration of Laser Scanning for Excavation Measurement

Author(s)
Geraldine S. Cheok, Robert R. Lipman, Christoph J. Witzgall, Javier Bernal, William C. Stone
The use of a scanning laser to measure terrain changes due to excavation at a construction site is described. The objective at this phase of the project is to

Driving Autonomously Offroad up to 35 km/h

Author(s)
David Coombs, Karl Murphy, Alberto Lacaze, Steven Legowik
A robotic HMMWV (a.k.a. "humvee") drives autonomously offroad at speeds up to 35 km/h (10 m/s, 20 mph). Key features of the implementation that enable driving

Dimensional Metrology of Millimeter- and Sub-millimeter-scale Components

Author(s)
Theodore V. Vorburger, Jun-Feng Song, Joseph Fu, M Tundermann, Thomas Brian Renegar, Theodore D. Doiron, N G. Orji
Decreasing sizes and tolerances of engineering components bring a demand for decreasing uncertainty in the dimensional measurements of these parts. Hence there

Contact-Pad Design for High-Frequency Silicon Measurements

Author(s)
Dylan Williams, A. C. Byers, V. C. Tyree, Dave K. Walker, J. J. Ou, X. Jin, M. Piket-Moy, C. Hu
We measure and compare the electrical parasitics of contact pads of different designs fabricated on silicon integrated circuits and develop a strategy for

Antenna Range Imaging

Author(s)
Ronald C. Wittmann, Michael H. Francis
We present a preliminary evaluation of a microwave measurement system that has been designed to determine electromagnetic fields in the quiet-zone of an antenna

Low-Cost, Broadband Absorber Measurements

Author(s)
David R. Novotny, Robert T. Johnk, Arthur Ondrejka
We present a method for evaluating broadband absorber in a non-ideal testing environment. Using broadband, short impulse TEM horns, a frequency-rich spectrum

Mutation Operators for Specifications

Author(s)
Paul E. Black, Vadim Okun, Yaacov Yesha
Testing has a vital support role in the software engineering process, but developing tests often takes significant resources. A formal specification is a
