Crystal Chemistry and Crystallography of the Aurivillius Phase Bi 5 AgNb 4 O 18

October 18, 2004
Author(s)
Winnie K. Wong-Ng, Qingzhen Huang, Lawrence P. Cook, Igor Levin, James A. Kaduk, Alan D. Mighell, J Suh
Bi 5AgNb 4O 18 is a new phase, which was discovered during the phase equilibrium study of the Bi 2O 3-Ag 2O-Nb 2O 5 system. Bi 5AgNb 4O 18 was prepared at 750 C and is stable in air up to its melting temperature of 1160.1 5.0 C. Results of a Rietveld

Reference Scaffolds for Characterization of Porosity (Poster)

October 18, 2004
Author(s)
John A. Tesk
ASTM Task Force F04.42.06 was formed with the objective of developing reference scaffolds, with the initial thrust focused on porosity.Three dimensional test-scaffolds were fabricated by two 3-Dimensional rapid prototyping methods. Visual examinations and

Estimating Multiple-Reflection Uncertainties in Spherical Near-Field Measurements

October 17, 2004
Author(s)
Michael H. Francis, Jeffrey R. Guerrieri, Katherine MacReynolds, Ronald C. Wittmann
We propose a method to estimate multiple-reflection effects on test-antenna pattern and gain uncertainties in the far field derived from spherical near-field measurements. To estimate these uncertainties we make a near-field measurements on two spheres

Practical Implementation of Probe-Position Correction in Near-field Planar Scanning Measurements

October 17, 2004
Author(s)
Jeffrey R. Guerrieri, Katherine MacReynolds, Michael H. Francis, Ronald C. Wittmann, Douglas T. Tamura
Planar near-field measurements require taking amplitude and phase data on an accurate and equal space grid on the plane in front of the antenna under test. The position accuracy on this grid has been determined to be '/50. As frequencies become higher

Adaptive Road Detection through Continuous Environment Learning

October 15, 2004
Author(s)
M Foedissch, A Takeuchi
The Intelligent Systems Division of the National Institute of Standards and Technology has been engaged for several years in developing real-time systems for autonomous driving. A road detection program is an essential part of the project. Previously we

New Insights into Threshold Voltage Shifts for Ultrathin Gate Oxides

October 15, 2004
Author(s)
Da-Wei Heh, Eric M. Vogel, J B. Bernstein
Threshold voltage (Vth) shifts of p- and n-channel MOSFETs during a stress are analyzed from both experiment and simulation. The result of the analysis showed that Vth shift is mainly induced by the carrier channel mobility degradation. This result can

NVNA Users Forum: Mission and Overview

October 12, 2004
Author(s)
Catherine A. Remley, Dominique Schreurs, Wendy Van Moer
This paper introduces the NVNA Users' Forum, an informal discussion group devoted to sharing information and issues related to instrumentation utilized in vector large-signal network analysis of microwave circuits and systems that contain nonlinear

Wide-Band Slot Antennas with CPW Feed Lines: Hybrid and Log-Periodic Designs

October 11, 2004
Author(s)
Alpesh Bhobe, Christopher L. Holloway, Melinda Piket-May, Richard Hall
In microwave and millimeter wave applications, slot antennas fed by coplanar waveguides (CPW) are receiving increasing attention. These antennas have several useful properties, such as wider bandwidth as compared to microstrip patch antennas and easier

Controlling the Dynamics of a Single Atom in Lateral Atom Manipulation

October 8, 2004
Author(s)
Joseph A. Stroscio, Robert Celotta
We study the dynamics of a single Co atom during lateral manipulation on a Cu(111) surface in a low temperature scanning tunneling microscope. The Co binding site locations are revealed in a detailed image that results from lateral Co atom motion within

Electrostatic Discharge Protection For Embedded-Sensor Systems-On-a-Chip

October 8, 2004
Author(s)
Javier A. Salcedo, Juin J. Liou, Muhammad Afridi, Allen R. Hefner Jr., Ankush Varma
The robustness of Embedded-Sensor (ES) System-on-a-Chip (SoC) applications involves several design constrains that require a unique assessment. For example, space-efficient electrostatic discharge protection (ESD) must be provided to protect the CMOS

Adaptive Real-Time Road Detection Using Neural Networks

October 6, 2004
Author(s)
M Foedissch, A Takeuchk
We have developed an adaptive real-time road detection application based on Neural Networks for autonomous driving. By taking advantage of the unique structure in road images, the network training can be processed while the system is running. The algorithm

Building Regulatory Systems in a Post-September 11 World.

October 6, 2004
Author(s)
Richard W. Bukowski
The September 11, 2001 attacks in the United States have initiated a significant discussion and rethinking among building regulators not only in the U.S., but also around the world. While most quickly state that regulations should not require that

Planning for On-Road Driving Through Incrementally Created Graphs

October 6, 2004
Author(s)
Stephen B. Balakirsky, Christopher J. Scrapper Jr
A general-purpose hierarchical planning framework that allows for cost-optimal, logic-constrained plans will be presented. This framework will be applied to planning an on-road path for an autonomous vehicle traveling amongst moving and stationary objects

Relating Gloss Loss to Topographical Features of a PVDF Coating

October 6, 2004
Author(s)
J Faucheu, Li Piin Sung, K Wood, Jonathan W. Martin
Semi-gloss commercial poly(vinylidene fluoride) (PVDF) coatings typically have 60o gloss values between 20 and 50. Gloss is affected by PVDF crystallite structures and by the pigmentation. In this paper, we have demonstrated that for some pigmented PVDF
