Letter to the Editor of the CTBUH Journal

December 1, 2011
Author(s)
Sivaraj Shyam-Sunder, Jason D. Averill, Fahim Sadek
NIST was invited to comment on the articles written for a special issue of the CTBUH Journal, marking the ten years passed since the 2001 9/11 attacks on the World Trade Center. This letter to the editor reacts to the role of the NIST WTC Investigation

Nanofibers for RF and Beyond

December 1, 2011
Author(s)
Thomas M. Wallis, Kichul Kim, Pavel Kabos, Dejan Filipovic
In order to realize new interconnect concepts based on nanofibers, reliable metrology is required. Given the clock-speeds of integrated circuits in the present as well as the foreseeable future, this metrology must be compatible with radio frequencies (RF)

Noise floor reduction of an Er:fiber laser-based photonic microwave generator

December 1, 2011
Author(s)
Haifeng (. Jiang, Jennifer A. Taylor, Franklyn J. Quinlan, Tara M. Fortier, Scott A. Diddams
Commercially available erbium-doped mode-locked fiber lasers are compact, robust, and suitable to be the frequency divider of an ultra-low phase noise photonic microwave generator. However, for a mode-locked fiber laser with repetition rate of a few

Objective Evaluation of Imager Performance

December 1, 2011
Author(s)
Francine K. Amon, Dennis D. Leber, Nicholas Paulter
We describe a method by which the evaluation and characterization of the performance of an imager can be done objectively and scientifically, that is, without routine operator interpretation. Although this method is demonstrated herein for passive long

Performance of Face Recognition Algorithms on Compressed Images

December 1, 2011
Author(s)
George W. Quinn, Patrick J. Grother
This report provides a comprehensive assessment of the ability of face recognition algorithms to compare compressed standard face images. Six well performing algorithms from the Multiple Biometric Evaluation (MBE) 2010 Still Face Track are used to compare

Predicted Energy Resolution of a Running-Sum Algorithm for Microcalorimeters

December 1, 2011
Author(s)
Bradley K. Alpert, William B. Doriese, Joseph W. Fowler, Joel N. Ullom
The energy resolution of a high-pulse-rate filtering algorithm recently introduced by Hui Tan et al., based on running sums of TES microcalorimeter output streams, is predicted from average pulse shape and noise autocovariance. We compare with empirical
