An Efficient Power-Saving Mechanism for Integration of WLAN and WWAN Networks

October 1, 2005
Author(s)
San-Nan K. Lee, S H. Seo, Nada T. Golmie
We have implemented a quantum key distribution (QKD) system with polarization encoding at 850 nm over 1 km of optical fiber. The high-speed management of the bit-stream, generation of random numbers and processing of the sifting algorithm are all handled

Carbon Nanotube-Based Coatings for Laser Power and Energy Measurements

October 1, 2005
Author(s)
John H. Lehman, Natalia Varaksa, Evangelos Theocharous, Anne Dillon
We describe carbon nanotube (CNT) based coatings for thermal detectors for laser power and energy measurements. The value of thermal properties of CNTs obtained from the literature indicates that such coatings have desirable properties such as low thermal

Channel-Adaptive Relaying in Mobile Ad Hoc Networks with Fading

October 1, 2005
Author(s)
Michael R. Souryal, Nader Moayeri
This paper describes an approach for relaying in multihop networks that adapts to the time-varying channel and exploits spatial diversity to mitigate multipath fading. Ignored in some simulation-based performance analyses, fading arises from multipath

Characterization of Normally-off SiC Vertical JFET Devices and Inverter Circuits

October 1, 2005
Author(s)
Jih-Sheng Lai, H. Yu, J. Zhang, Y. Li, Kuang Sheng, J.H. Zhao, Allen R. Hefner Jr.
A normally-off SiC JFETs has been characterized under static and dynamic operating conditions. Two application oriented inverter circuits were constructed for additional tests under soft- and hard-switching conditions. The single-phase soft-switching

Combinatorial Materials Synthesis and High-Throughput Characterization

October 1, 2005
Author(s)
Ichiro Takeuchi, Lauterbach Jochen, Michael J. Fasolka
The pace at which major technological changes take place is often dictated by the rate at which new materials are discovered, and timely arrival of new materials has always played a key role in bringing advances to our society. There is no wonder then that

CPM: A Core Model for Product Data

October 1, 2005
Author(s)
Steven J. Fenves, Sebti Foufou, Conrad Bock, Ram D. Sriram
The support of PLM throughout the product life, from the product?s conceptualization to its disposal, requires reliable, complete and efficient data models. The Core Product Model (CPM), initially developed at NIST for a number of in-house research

Criteria for Exact Qudit Universality

October 1, 2005
Author(s)
Stephen Bullock, G K. Brennen, Dianne M. O'Leary
The n-qubit concurrence canonical decomposition (CCD) is a generalization of the two-qubit canonical decomposition SU(4)=[SU(2) (x) SU(2)] ? [SU(2) (x) SU(2)], where ? is the commutative group which phases the maximally entangled Bell basis. A prequel

Developing a Difficulty Metric for Open Source Analytic Tasks

October 1, 2005
Author(s)
T T. Hewett, Jean C. Scholtz
Our goal is to produce metrics for assessing the impact of software tools and environments produced for the intelligence community. To this end we need to understand the variables that make some analytic tasks harder than others and to determine which data

Development and Evaluation of a Reference Measurement Procedure for the Determination of Estradiol-17 in Human Serum Using Isotope-Dilution Liquid Chromatography-Tandem Mass Spectrometry

October 1, 2005
Author(s)
Susan S. Tai, Michael J. Welch
Estradiol is the most potent natural estrogen and is derived from the ovaries. Its concentration in blood is measured to determine ovarian function. A reference measurement procedure (RMP) for estradiol in serum involving isotope-dilution (ID) coupled with

Direct Preparation of Particles From Liquid Suspension for ESEM or SEM Analysis

October 1, 2005
Author(s)
Scott A. Wight, Richard D. Holbrook
A simplified method for the preparation of particles from liquid suspensions has been developed. Particles are deposited directly on carbon planchets for rapid analysis by environmental scanning electron microscopy or by conventional scanning electron

DNSSEC Test and Measurement Tools: Secure Zone Integrity Tester v0.9.3, Zone Monitoring Tool v0.9, dns Trace : traffic statistics collection tool, querysim : DNS query workload monitoring tool

October 1, 2005
Author(s)
Scott W. Rose, Darrin J. Santay, Douglas Montgomery, Kevin L. Mills, Stephen Quirolgico, M Ramaswamy
We have implemented a quantum key distribution (QKD) system with polarization encoding at 850 nm over 1 km of optical fiber. The high-speed management of the bit-stream, generation of random numbers and processing of the sifting algorithm are all handled

DTR-MESA-SYS0070012: System Reference Architecture

Dynamic Susceptibility of Nanopillars

October 1, 2005
Author(s)
N Dao, I Dumitru, L Spinu, S L. Whittenburg, Michael J. Donahue, J C. Lodder
We have calculated dynamic susceptibility of patterned cobalt and Permalloy pillars with a diameter of 50 nm and different pillar heights using micromagnetic simulations. The resonance modes obtained from these simulations are compared to the results

Embedding MPEG-7 Metadata Within a Media File Format

October 1, 2005
Author(s)
Wo L. Chang
Embedding metadata within a media file format becomes evermore popular for digital media. Traditional digital media files such as MP3 songs and JPEG photos do not carry any metadata structures to describe the media content until these file formats got

Enhanced Quantum State Detection Efficiency Through Quantum Information Processing

October 1, 2005
Author(s)
T Schaetz, M D. Barrett, D. Leibfried, J. Britton, J. Chiaverini, W M. Itano, J. D. Jost, Emanuel Knill, C. Langer, David J. Wineland
