Slap Fingerprint Segmentation Evaluation 2004 Analysis Report

March 1, 2005
Author(s)
Brad Ulery, R. A. Hicklin, Craig I. Watson, Michael D. Indovina, Kayee Hanaoka
The Slap Fingerprint Segmentation Evaluation 2004 (Slap Seg04) was conducted to assess the accuracy of algorithms used to segment slap fingerprint images into individual fingerprint images. Segmenters from ten different organizations were evaluated on data

Technology for the Information Commons in a Special Library

March 1, 2005
Author(s)
Nancy Allmang, Rosa Liu
Recently, Information Commons has become a buzzword with two meanings--a gathering place for collaborating and sharing new technologies, or a virtual spot for disseminating intellectual information. This case study highlights technologies utilized by a

Testing BIOS Interrupt 0x13 Based Software Write Blockers

March 1, 2005
Author(s)
James R. Lyle, Paul E. Black
We report observations and experience in the Computer Forensics Tool Testing (CFTT) project while developing methodologies to test interrupt 0x13 based software write block (SWB) tools. A write blocker allows access to all data on a storage device while

Through-Thickness Texture Inhomogeneity in a Recrystallized Al-Mg Alloy

March 1, 2005
Author(s)
J -. Liu, Stephen W. Banovic, Frank S. Biancaniello, Rodney D. Jiggetts
Through-thickness texture of a rolled and recrystallized Al-Mg continuous cast alloy was examined using electron backscattered diffraction. Results showed the recrystallization texture through thickness of the sheet was inhomogeneous with Cube 001}

Toward Data Standards for Proteomics Data

March 1, 2005
Author(s)
Veerasamy Ravichandran, Ram D. Sriram
Biologists have traditionally worked with relatively small data sets and shared results only with others working on similar biological systems. With the advent of genomics, and now proteomics, they are faced with exponentially growing sets of highly inter

Understanding Failure Response in Service Discovery Systems

March 1, 2005
Author(s)
Kevin L. Mills, Stephen Quirolgico, Christopher E. Dabrowski
Service discovery systems enable distributed components to find each other without prior arrangement, to express capabilities and needs, to aggregate into useful compositions, and to detect and adapt to changes. First-generation discovery systems can be

Web-Based 3D Visualization in a Digital Library of Mathematical Functions

March 1, 2005
Author(s)
Qiming Wang, Bonita V. Saunders
The National Institute of Standards and Technology (NIST) is developing a digital library of mathematical functions to replace the widely used National Bureau of Standards Handbook of Mathematical Functions published in 1964 [1]. The NIST Digital Library

X-ray Absorption Spectroscopy to Probe Surface Composition and Surface Deprotection in Photoresist Films

March 1, 2005
Author(s)
Joseph~undefined~undefined~undefined~undefined~undefined Lenhart, Daniel A. Fischer, S Sambasivan, Eric K. Lin, Ronald L. Jones, Christopher Soles, Wen-Li Wu, D M. Goldfarb, M Angelopoulos
We utilize near edge x-ray absorption fine structure spectroscopy (NEXAFS) to provide chemical insight into surface chemical effects in model photo-resist films. First, NEXAFS was used to examine the resist/air interface including surface segregration of a

Detailed Study and Projection of Hard Breakdown Evolution in Ultra-Thin Gate Oxides

February 28, 2005
Author(s)
John S. Suehle, Baozhong Zhu, Yuan Chen, J B. Bernstein
The mechanism responsible for post soft-breakdown leakage current increase in ultra-thin oxides depends on the nature of the conducting filament formed at the instant of dielectric breakdown. The conductance of the filament formed during soft breakdown has

The GOES Time Code Service, 1974 - 2004: A Retrospective

February 27, 2005
Author(s)
Michael A. Lombardi, D. W. Hanson
After nearly 30 years of continuous operation, NIST ended its Geostationary Operational Environmental Satellites (GOES) time code service at 0 hours, 0 minutes Coordinated Universal Time (UTC) on January 1, 2005. This event marked the end of an important

Simultaneous state measurement of coupled Josephson phase qubits

February 25, 2005
Author(s)
Robert McDermott, Raymond Simmonds, Matthias Steffen, Ken B. Cooper, Katarina Cicak, Kevin Osborn, Seongshik Oh, David P. Pappas, John M. Martinis
One of the many challenges of building a scalable quantum computer is singleshot measurement of all the quantum bits (qubits). We have used simultaneous single-shot measurement of coupled Josephson phase qubits to directly probe interaction of the qubits

Characterization of Ordered Mesoporous Silica Films Using Small Angle Neutron Scattering and X-Ray Porosimetry

February 23, 2005
Author(s)
B D. Vogt, R A. Pai, Hae-Jeong Lee, R C. Hedden, Christopher L. Soles, Wen-Li Wu, Eric K. Lin, Barry J. Bauer, J J. Watkins
Ordered mesoporous silica films were synthesized using pre-organized block copolymer templates in supercritical carbon dioxide. Poly(ethylene oxide-block-propylene oxide-block-ethylene oxide), PEO-b-PPO-b-PEO, films doped with p-toluenesulfonic acid (p TSA
