Ground Truth Data Using 3D Imaging for Urban Search and Rescue Robots

October 14, 2009
Author(s)
Nicholas A. Scott, Alan M. Lytle
The National Institute of Standards and Technology (NIST) is leading an effort to develop performance standards for ur- ban search and rescue robots (US&R). An important com- ponent of developing performance standards for these robots is capturing ground

Mobile Forensic Reference Materials: a Methodology and Reification

October 14, 2009
Author(s)
Wayne Jansen, Aurelien M. Delaitre
This report concerns the theoretical and practical issues with automatically populating mobile devices with reference test data for use as reference materials in validation of forensic tools. It describes an application and data set developed to populate

October 2009 SRM Spotlight

October 14, 2009
Author(s)
Regina R. Montgomery
The SRM Spotlight is a newsletter published by the Measurement Services Division for users of NIST standard reference materials. The Spotlight announces new reference materials and provides information about their use. In addition, this newsletter contains

Simplified Analysis of Matcher Performance and Fusion

October 14, 2009
Author(s)
Vladimir N. Dvornychenko
Provides some first-order techniques for analyzing matcher performance. A novel argument is used to derive the power-law as a kind of baseline for analyzing matcher performance. The power-law is then applied to two situations: a) CMC curves, and b) fusion

Adhesion, Copper Voiding, and Debonding Kinetics of Copper/Dielectric Diffusion Barrier Films

October 13, 2009
Author(s)
Ryan P. Birringer, Roey Shaviv, Thomas Mountsier, Jon Reid, Jian Zhou, Roy H. Geiss, David T. Read, Reinhold Dauskardt
Effects of the chemistry of electroplated copper films on stress-induced voiding and adhesion between the films and a SiN barrier layer are reported. The void density as observed by scanning electron microscopy decreased markedly with increasing Cu purity

NIST SRM (Standard Reference Material) 2460/2461 Standard Bullets and Casings Project

October 13, 2009
Author(s)
Jun-Feng Song, Thomas Brian Renegar, Xiaoyu Alan Zheng, Robert M. Thompson, Richard M. Silver, Martin M. Ols, Ted T. Vorburger
The National Institute of Standards and Technology (NIST) in collaboration with the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF) has developed the Standard Reference Material (SRM) 2460 Bullets and 2461 Cartridge Cases. NIST has also

An efficient, optical fiber-based waveguide interface to a single quantum dipole

October 12, 2009
Author(s)
Marcelo I. Davanco, Kartik A. Srinivasan
We theoretically investigate a single emitter embedded in a hybrid optical waveguide that proves highly efficient, optical fiber access to the dipole transition. A photoluminescence collection efficiency above 70 \% and an approximately 15 dB transmission

Innovations in Maximum Likelihood Quantum State Tomography

October 9, 2009
Author(s)
Scott C. Glancy, Emanuel H. Knill, Thomas Gerrits, Tracy S. Clement, Brice R. Calkins, Adriana E. Lita, Aaron J. Miller, Alan L. Migdall, Sae Woo Nam, Richard P. Mirin
At NIST we are engaged in an experiment whose goal is to create superpositions of optical coherent states (such superpositions are sometimes called "Schroedinger cat" states). We use homodyne detection to measure the light, and we apply maximum likelihood

Results of an international photomask linewidth comparison of NIST and PTB

October 9, 2009
Author(s)
Bernd Bodermann, Detleff Bergmann, Egbert Buhr, Wolfgang Haebler-Grohne, Harald Bosse, James E. Potzick, Ronald G. Dixson, Richard Quintanilha, Michael T. Stocker, Andras Vladar, Ndubuisi George Orji
In preparation of the international Nano1 linewidth comparison on photomasks between 9 national metrology institutes, NIST and PTB have started a bilateral linewidth comparison in 2008, independent of and prior to the Nano1 comparison in order to test the

Volume Estimation of Molded Artifacts by B-Splines

October 9, 2009
Author(s)
David E. Gilsinn, Bruce R. Borchardt, Amelia Tebbe
The volumes of two industrially molded non-metallic artifacts were estimated using surface data obtained by a coordinate measuring machine. A tensor product of B-splines was used to model the probed data points on the surface and the Divergence Theorem was

Mathematical Metrology for Evaluating a 6DOF Visual Servoing System

October 8, 2009
Author(s)
Tommy Chang, Tsai H. Hong, Milli Shah, Roger D. Eastman
In this paper we develop the best homogeneous matrix trans- formation to fit two streams of dynamic six-degree-of-freedom (6DOF) data for evaluating perception systems using ground truth. In particular, we compare object position and orien- tation results

Quantifying the Performance of MT-Connect in a Distributed Manufacturing Environment

October 8, 2009
Author(s)
John L. Michaloski, Byeong Eon Lee, Frederick M. Proctor, Sid Venkatesh, Sidney Ly
In the CNC manufacturing world, the continuing pressure to reduce costs and improve time to market places a premium on smarter ways of manufacturing and intensifies the need to integrate feedback from the shop floor into the enterprise business systems

Quantitative Assessment of Robot-generated Maps

October 8, 2009
Author(s)
Christopher J. Scrapper Jr, Rajmohan Madhavan, Adam S. Jacoff, R Lakaemper, A Censi, Afzal A. Godil, Asim Wagan
Mobile robotic mapping is now considered to be a sufficiently mature field with demonstrated successes in various domains. While there has been much progress made in the development of computationally efficient and consistent mapping schemes, it is still

Viscoelastic Properties of Confined Polymer Films Measured via Thermal Wrinkling

October 8, 2009
Author(s)
Kirt A. Page, Edwin Chan, Se Hyuk Im, Derek L. Patton, Rui Huang, Christopher Stafford
We present a new measurement technique to quantify the viscoelastic properties of polymer thin films. This approach utilizes thermally-induced surface wrinkling to measure the rubbery modulus and shear viscosity of polymer thin films. Specifically, by
