George W. Arnold, Gerald FitzPatrick, David A. Wollman, Thomas L. Nelson, Paul A. Boynton, Galen H. Koepke, Allen R. Hefner Jr., Cuong Nguyen, Jeffrey A. Mazer, Dean Prochaska, Marianne M. Swanson, Tanya L. Brewer, Victoria Yan Pillitteri, David H. Su, Nada T. Golmie, Eric D. Simmon, Allan C. Eustis, David Holmberg, Steven T. Bushby, Michael D. Janezic, Ajitkumar Jillavenkatesa
The Energy Independence and Security Act (EISA) of 2007 requires that NIST develop a framework of standards for the Smart Grid. This document is the second release of the framework first published in January, 2010. It covers the activities and outputs of

DHS/NIST Workshop on Homeland Security Modeling & Simulation, June 14-15, 2011

December 19, 2011
Author(s)
Charles R. McLean, Yung-Tsun Lee, Sanjay Jain, Charles W. Hutchings
The U. S. Department of Homeland Security (DHS) Science and Technology Directorate and the National Institute of Standards and Technology (NIST) Engineering Laboratory (EL) jointly hosted a Homeland Security Modeling & Simulation (M&S) Workshop on 14 & 15

Towards realization of a large-area, LED-based solar simulator

November 27, 2011
Author(s)
Behrang H. Hamadani, Kangbin Chua, John F. Roller, Howard W. Yoon, Brian P. Dougherty
LED-based solar simulators have shown great promise as alternative light sources for indoor testing of PV cells as compared to their traditional counterparts. However, large-area uniform illumination more suitable for larger cells and module measurements

Quantum-based Voltage Waveform Synthesis

November 11, 2011
Author(s)
Samuel P. Benz
More than a decade of research and development was required to practically exploit the quantum behavior of superconducting Josephson junctions for ac applications. Sine waves and arbitrary waveforms had to be synthesized with sufficiently large voltage

November 2011 SRM Spotlight

October 24, 2011
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

Prototype cantilevers for quantitative lateral force microscopy

September 27, 2011
Author(s)
Mark Reitsma, Richard S. Gates, Lawrence H. Friedman, Robert F. Cook
Prototype cantilevers that enable quantitative micro- to nano-scale surface force measurements using contact-mode atomic force microscopy (AFM) are presented. The “Hammerhead” cantilevers allow precise optical lever system calibrations for cantilever

Extending single-photon optimized superconducting transition edge sensors beyond the single-photon counting regime

September 19, 2011
Author(s)
Thomas Gerrits, Brice R. Calkins, Nathan A. Tomlin, Adriana E. Lita, Alan L. Migdall, Sae Woo Nam, Richard P. Mirin
Photon number resolving transition-edge sensors (TES) are the cutting-edge enabling technology for high quantum efficiency photon number counting. The TES developed at NIST reliably show system detection efficiencies of more than 95%, and even approach 99%

International comparisons of optical fiber power measurements

September 19, 2011
Author(s)
Igor Vayshenker, David J. Livigni, Xiaoyu X. Li, John H. Lehman
We discuss the results of optical fiber power meter (OFPM) measurements at 1310 and 1550 nm made by NIST and seven national measurement institutes (NMIs). We also describe transfer standards and the associated uncertainties. The comparisons show a

Graphene: A New Horizon for Modern Technology

September 15, 2011
Author(s)
Jan Obrzut
Graphene has the potential to improve a long list of daily electronics that are the foundation of the modern computing revolution. In step with research in renewable energy, graphene can and has been used in efficient, flexible solar cells. Crossing the

BUSINESS OBJECTS FOR INDUSTRIAL DATA STANDARDS

August 31, 2011
Author(s)
Allison Barnard Feeney, Keith A. Hunten
Business objects, as proposed for inclusion in the ISO 10303 family of industrial data standards developed in ISO TC 184/SC4 (SC4), are a layer over the ISO 10303 architecture that is intended to simplify and make the complex standards more accessible to a

IEEE RAS Standing Committee for Standards Activities: History and Status Update

July 21, 2011
Author(s)
Rajmohan Madhavan, Wonpil Yu, C Biggs, Craig I. Schlenoff, Hui-Min Huang
The Standing Committee for Standards Activities (SCSA) under the Industrial Activities Board (IAB) of the IEEE Robotics and Automation Society (RAS) is working together with the research and industrial communities and other Standards Developing

Chapter 21 Calibration of Aerosol Instruments

July 5, 2011
Author(s)
Bean T. Chen, Robert A. Fletcher, Yung-Sung Cheng
This chapter reviews calibration techniques relevant to aerosol measurement devices, such as sizing instruments, condensation nuclei counters, and mass monitors. The generation methods for test aerosols and important parameters in instrument calibration

A Roadmap for STEP-NC Enabled Interoperable Manufacturing

June 17, 2011
Author(s)
Fiona Zhao, Frederick M. Proctor, Martin Hardwick, Sid Venkatesh, David Odendahl, Xun Xu
STEP-NC is the result of a ten-year international effort to replace the RS274D (ISO 6983) G and M code standard with a modern associative language. The new standard connects CAD design data to CAM process data so that smart applications can understand both
