Lattice-based optical clock using an even isotope of Yb

September 12, 2007
Author(s)
Zeb Barber, C Hoyt, Jason Stalnaker, Nathan D. Lemke, Christopher W. Oates, Tara M. Fortier, Scott A. Diddams, Leo W. Hollberg
We describe progress toward an optical lattice clock based on an even isotope of Yb. The 1S_0 - P_0 clock resonance in 174Yb is accessed using a magnetically induced spectroscopic technique. Using ~1 mT static magnetic fields and ~10 uW of probe light

Hemispherical Imaging of Skin With Polarized Light

January 15, 2007
Author(s)
J C. Ramella-Roman, Bruno Boulbry, Thomas A. Germer
Polarized light imaging has been used in the past for skin-cancer edge detection from skin lesions. In the standard imaging modality, the source, detector, and sample are usually aligned in the same plane, and the effect of the air-skin boundary is

Hyperspectral Image Projector for Advanced Sensor Characterization

December 4, 2006
Author(s)
Steven W. Brown, Joseph P. Rice, Jorge E. Neira, Bettye C. Johnson
In this work, we describe radiometric platforms able to produce realistic spectral distributions and spatial scenes for the development of application-specific metrics to quantify the performance of sensors and systems. Using these platforms, sensor and

Investigating Global Behavior in Computing Grids

September 1, 2006
Author(s)
Kevin L. Mills, Christopher E. Dabrowski
This paper presents an executable model of grid computing systems and a measurement approach, based on multidimensional analysis, to understand global behavior in a complex system. Specifically, we investigate effects of spoofing attacks on the scheduling
