Approximating Periodic Solutions of Autonomous Delay Differential Equations

November 30, 2006
Author(s)
David E. Gilsinn
Machine tool chatter has been characterized as isolated periodic solutions or limit cycles of delay differential equations. Determining the amplitude and frequency of the limit cycle is sometimes crucial to understanding and controlling the stability of

Evidence for Internal Stresses Induced by Nanoimprint Lithography

November 30, 2006
Author(s)
Hyun Wook Ro, Yifu Ding, Hae-Jeong Lee, Daniel R. Hines, Ronald L. Jones, Eric K. Lin, Alamgir Karim, Wen-Li Wu, Christopher L. Soles
The thermal embossing form of nanoimprint lithography is used to pattern arrays of nanostructures into several different polymer films. The shape of the imprinted patterns is characterized with nm precision using both X-ray scattering and reflectivity

Firebrand Production From Burning Vegetation

November 30, 2006
Author(s)
Samuel L. Manzello, Alexander Maranghides, William E. Mell, Thomas G. Cleary, Jiann C. Yang
A series of real scale fire experiments were performed to determine the size and mass distribution of firebrands generated from Douglas-Fir (pseudotsuga menziesii) trees. The results of the real scale fire experiments were used to determine firebrand sizes

Recommendation for Obtaining Assurances for Digital Signature Applications

November 30, 2006
Author(s)
Elaine B. Barker
Entities participating in the generation or verification of digital signatures depend on the authenticity of the process. This Recommendation specifies methods for obtaining the assurances necessary for valid digital signatures: assurance of domain

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

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
