Ring Expansion Reactions in the Thermal Decomposition of t-Butyl-1,3-Cyclopentadiene

November 30, 2006
Author(s)
William S. McGivern, Jeffrey A. Manion, Wing Tsang
The thermal decomposition of t-butyl-1,3-cyclopentadiene has been investigated in single pulse shock tube studies at shock pressures of 182 260 kPa and temperatures of 996 1127 K. Isobutene (2-methylpropene), 1,3-cyclopentadiene, and toluene are observed

A Taxonomy of Definitions for Usability Studies in Biometrics

November 27, 2006
Author(s)
Ross J. Micheals, Brian C. Stanton, Mary F. Theofanos, Shahram Orandi
Historically, usability research strives to focus on user behavior in a manner that is as system independent as possible. Although ¿ISO/IEC JTC 1/SC 37 Standing Document 2 ¿ Harmonized Biometric Vocabulary, Draft N1779¿ provides a foundation towards common

Real-Time Speaker Verification with a Microphone Array

November 27, 2006
Author(s)
G. Mei, R. Xu, R. Lao, C. Kwan, Vincent M. Stanford
Real-time speaker verification, with speech acquired using the NIST Mk-III microphone array and an autodirective beamforming algorithm, is demonstrated. The software and hardware backbone of the demonstration is the NIST Smart Flow System and Mk-III Array

Synchronizing Multimodal Data Streams Acquired Using Commodity Hardware

November 27, 2006
Author(s)
Martial Michel, Vincent M. Stanford
We have developed tools and techniques that allow video frame level synchronization of multiple free-running commodity video cameras, microphones, and computer nodes using non-realtime operating systems. The techniques rely on physical audiovisual

High Temperature Superconductor Wires and Tapes

November 26, 2006
Author(s)
M. P. Paranthaman, V Selvamanickam, K Matsumoto, Luigia Gianna, Wei-xian Zhang, P Goyal, Winnie Wong-Ng
High Temperature Superconductor Wires and Tapes was one of the MS&T2006 symposia (October 15-19, 2006; Duke Energy Center, Cincinnati, Ohio) that covered recent advances in the area of high temperature superconductor (HTS) wires and tapes. The symposium

Guide to Securing Computers Using Windows XP Home Edition

November 22, 2006
Author(s)
Shirley M. Radack
This bulletin summarizes the information provided in NIST SP 800-69 concerning the need to secure Windows XP Home Edition computers, and discusses the security protections that are available to reduce weaknesses, protect privacy, stop attacks and preserve

The OLES Imaging Metrology Program

November 22, 2006
Author(s)
Nicholas G. Paulter Jr.
The OLES Imaging Metrology Program is a broad-based interdisciplinary activity initiated and maintained for the development of metrology of digital imagery as applied to security, law enforcement, and corrections applications.

Drying Induced Variations in Physico-Chemical Properties of Amorphous Pharmaceuticals and Their Impact on Stability (I): Stability of aMonoclonal Antibody

November 21, 2006
Author(s)
Ahmad Abdul-Fattah, Vu Truong-Le, Luisa Yee, Lauren Nguyen, Devendra Kalonia, Marcus T. Cicerone, Michael Pikal
Both drying method and formulation had a significant impact on the properties of IgG1 powders, including storage stability. Among the drying methods, SSA was highest and perturbations in secondary structure were lowest with the spray dried preparations

Development of a Motion Imagery Quality Metric

November 20, 2006
Author(s)
J Irvine, Charles D. Fenimore, D Cannon, Donna Haverkamp, John W. Roberts, S Israel, L Simon, J Miller, A Aviles, Michelle Brennan
The motion imagery community would benefit from the availability of standard measures for assessing image interpretability. The National Imagery Interpretability Rating Scale (NIIRS) has served as a community standard for still imagery, but no comparable

Dynamic Lorentz Microscopy of Micromagnetic Structure in Magnetic Tunnel Junctions

November 20, 2006
Author(s)
Justin Shaw, R.H. Geiss, Stephen E. Russek
Lorentz microscopy was used to study the micromagnetic structure and magnetization reversal in magnetic tunnel junctions (MTJs) fabricated with different processing conditions including a preoxidation process. The authors find that the free layer in a MTJ

ECBCS Annex 47: Cost-Effective Commissioning Research

November 20, 2006
Author(s)
Natascha S. Milesi-Ferretti, Hannah Friedman, Marti Frank
In 2005, the Executive Committee of the International Energy Agency s (IEA) Energy Conservation in Buildings and Community Systems (ECBCS) program approved the start of a new four-year research project on building commissioning. Annex 47, on Cost-Effective

Metal-Insulator Transition Revisited for Cold Atoms in Non-Abelian Gauge Potentials

November 20, 2006
Author(s)
Indubala I. Satija, D C. Dakin, Charles W. Clark
We discuss the possibility of realizing metal-insulator transitions with ultracold atoms in two-dimensional optical lattices in the presence of artificial gauge potentials. Such transitions have been extensively studied for magnetic fields corresponding to

Summary of Latent Fingerprint work at NIST

November 20, 2006
Author(s)
Vladimir N. Dvornychenko, Michael D. Garris
This paper describes past and present fingerprint activity at NIST. While the primary focus is on latent fingerprints, the paper also surveys relevant general biometrics activity. The central focus of the paper is on the Latent Testing Workshop, held on

The Influence of NH 3 Anneal on the Crystallization Kinetics of HfO 2 Gate Dielectric Films

November 17, 2006
Author(s)
Patrick S. Lysaght, Joseph Woicik, Brendan Foran, Joel Barnett, Gennadi Bersuker, B H. Lee
HfO2 gate dielectric thin films have been exposed to anneal processing in NH3 and N2 ambient in order to decouple the influence of N incorporation from that of the thermal cycle alone. We report on the effectiveness of NH3 processing to introduce N into

INTEGRATED BRIDGE PROJECT DELIVERY AND LIFE CYCLE MANAGEMENT

November 16, 2006
Author(s)
Krishna Verma Verma, Thomas A. Siewert, F. Beckmann
This paper highlights developments that led the FHWA¿s Office of Bridge Technology, working with State departments of transportation (DOT) and the concrete and steel bridge industries, to launch a major initiative to identify available technologies and
