The Advanced Encryption Standard (AES): Raising the Bar for Cryptography

April 1, 2003
Author(s)
William E. Burr
This paper describes how the National Institute of Standards and Technology (NIST) selected the Advanced Encryption Standard (AES), a new standard symmetric key encryption algorithm that has been adopted for use by the U.S. Federal Government, for

The Bromine Doping of Polyacetylene

April 1, 2003
Author(s)
C. K. Chiang
The first doping experiment of polyacetylene performed by Chiang and Shirakawa in 1976 is described. The first successful doping experiment of polyacetylene impacted physics and chemistry in three aspects: 1) discovery of metallic conducting synthetic

The Development and Application of Cryocoolers Since 1985

April 1, 2003
Author(s)
Ray Radebaugh
Many significant new developments in cryocoolers have occurred since about 1985 that have lead to grealy improved efficiencies, lifetimes, compactness, and low temperature limits. Many of the improvements have been spurred by the requirements of several

The Eleventh Text Retrieval Conference (TREC 2002)

April 1, 2003
Author(s)
Ellen M. Voorhees
TREC 2002 is the latest in a series of workshops designed to foster research in information retrieval and related tasks. This year's conference consisted of seven different tasks: cross-language retrieval, filtering, interactive retrieval, novelty

The NIST Human ID Evaluation Framework

April 1, 2003
Author(s)
Ross J. Micheals, Patrick J. Grother, P J. Phillips
In this paper, we investigate the utility of static anthropometric distances as a biometric for human identification. The 3D landmark data from the CAESAR database is used to form a simple biometric consisting of distances between fixed rigidly connected

The NIST Microforce Realization and Measurement Project

April 1, 2003
Author(s)
David B. Newell, Edwin R. Williams, John A. Kramar, Jon R. Pratt, Douglas T. Smith
The National Institute of Standards and Technology (NIST) has launched a five-year Micro-force Realization and Measurement project focusing on the development of an instrument and laboratory capable of realizing and measuring the SI unit of force below

The TREC-2002 Filtering Track Report

April 1, 2003
Author(s)
S E. Robertson, Ian Soboroff
The TREC¿11 filtering track measures the ability of systems to build persistent user profiles which successfully separate relevant and non-relevant documents in an incoming stream. It consists of three major subtasks; adaptive filtering, batch filtering

The TREC-2002 Video Track Report

April 1, 2003
Author(s)
Alan Smeaton, Paul D. Over
TREC-2002 saw the second running of the Video Track, the goal of which was to promote progress in content-based retrieval from digital video via open, metrics-based evaluation. The track used 73.3 hours of publicly available digital video (in MPEG-1/VCD

Toward a Real-time Scheduler and Controller for Semiconductor Fabrication Systems

April 1, 2003
Author(s)
Hyeung-Sik Min, Albert T. Jones, Yuehwern Yih
The complexity of a semiconductor fabrication system is high because of complicated product flows, uncertain operation times, variable yields, changing products, and evolving technologies. Effective scheduling, which attempts (1) to predict accurately the

Traction-Free Vibrations of Finite Trigonal Elastic Cylinders

April 1, 2003
Author(s)
Paul R. Heyliger, Ward L. Johnson
The unrestrained, traction-free vibrations of finite elastic cylinders with trigonal material symmetry are studied using two approaches, based on the Ritz method, which formulate the weak form of the equations of motion in cylindrical and retangular

Ultrasonic Evaluation Methods Applicable to Polymer Concrete Composites

April 1, 2003
Author(s)
A Garbacz, Edward Garboczi
Polymer composites (PC) appear as useful materials for repair and protection of building structures, as well as for manufacturing pre-cast elements. In the case of pre-cast elements as well as repair materials, the usefulness and durability of polymer

Wind Speeds in ASCE 7 Standard Peak-Gust Map: Assessment

April 1, 2003
Author(s)
Emil Simiu, R Wilcox, Fahim Sadek, James J. Filliben
The ASCE 7 peak-gust map division of the conterminous United States into two adjacent wind speed zones does not reflect correctly the country's differentiated extreme wind climate. The methodology used to develop the map averages out real climatological

Wind Speeds in the ASCE 7 Standard Peak-Gust Map: An Assessment

April 1, 2003
Author(s)
Emil Simiu, R Wilcox, Fahim Sadek, James J. Filliben

XML for Capital Facilities

April 1, 2003
Author(s)
T L. Teague, Mark E. Palmer, R H. Jackson
Extensible Markup Language (XML) offers a promising enabling technology for improving the execution of capital projects and capital facility life cycle data management. XML provides the most value when industry practitioners agree to use a common

XML for Exchange of Weld Inspection Results

April 1, 2003
Author(s)
William G. Rippey, Timothy P. Quinn, John L. Michaloski
TECHNICAL SUMMARYIntroduction/Background SectionA system to demonstrate the transfer of weld inspection data between computer programs is described in this paper. The goal is effortless flow of the data between multi-vendor welding software applications

Mechanisms for the multistep spin reorientation of ultrathin Fe films on Gd

March 31, 2003
Author(s)
A P. Popov, A. V. Anisimov, David P. Pappas
The multistep spin reorientation transition of ultrathin iron films on bulk gadolinium is described theoretically. We find that it is necessary to include cubic terms in the magnetic anisotropy energy expansion in order to explain this phenomenon

Metrology for Molecular Electronics

March 31, 2003
Author(s)
Curt A. Richter, D R. Stewart
We discuss some of the complex issues associated with the metrology of molecular electronic devices and describe an electrical characterization method to assess molecular crossbar devices. Experimental data is shown for an eicosanoic acid crossbar device
