A robust algorithm for eye-diagram analysis

November 1, 2008
Author(s)
Jeffrey A. Jargon, Paul D. Hale, Chih-Ming Wang
We present a new method for analyzing eye diagrams that always provides a unique solution by making use of a robust, least-median-of-squares (LMS) location estimator. In contrast to commonly used histogram techniques, the LMS procedure is insensitive to

Derivation of the MODIS Aqua Point-Spread Function for Ocean Color Bands

September 11, 2008
Author(s)
Gerhard Meister, Yuqin Zong, Charles R. McClain
The Moderate Resolution Imaging Spectroradiometer (MODIS) on the Earth Observing System (EOS) Aqua platform has 9 spectral bands with center wavelengths from 412nm to 870nm that are used to produce the standard ocean color data products. Ocean scenes

A Virtual Rapid Chloride Permeability Test

July 15, 2007
Author(s)
Dale P. Bentz
The rapid chloride permeability test (RCPT), as it is commonly called, has been in existence for over 20 years and was standardized by ASTM over 15 years ago. The test is used extensively in the concrete industry for assessing concrete quality and is now

Improved Limits on Variation of the Fine Structure Constant and Violation of Local Position Invariance

May 29, 2007
Author(s)
Tara M. Fortier, Neil Ashby, James C. Bergquist, Marie Delaney, Scott A. Diddams, Thomas P. Heavner, Leo W. Hollberg, Wayne M. Itano, Steven R. Jefferts, K Kim, Windell Oskay, Thomas E. Parker, Jon H. Shirley, Jason Stalnaker, Filippo Levi, Luca Lorini
We report tests of Local Position Invariance (LPI) and constancy of fundamental constants from measurements of the frequency ratio of the 282-nm 199Hg + optical clock transition to the ground-state hyperfine splitting in 133Cs. Analysis of the frequency

Comment on the CASIA v1 Iris Dataset

March 26, 2007
Author(s)
P J. Phillips, K W. Bowyer, P J. Flynn
The paper by Ma et al. [1] made a number of contributions to iris recognition including a novel iris recognition algorithm, a benchmark of standard approaches to iris recognition, and the establishment of an iris data set. The data set, Chinese Academy of

Linewidth Measurement Based on Automatically Matched and Stitched Images

January 1, 2007
Author(s)
Wei Chu, Joseph Fu, Ronald G. Dixson, Theodore V. Vorburger
The emergence of ultra-sharp carbon nanotube (CNT) tips provides a new approach to minimize the distortion of the measured linewidth profile caused by interaction with the fmite probe tip size. However, the inevitable tilt angle resulting from attaching

The National Marine Mammal Tissue Bank Specimen Inventory
