Measuring the Performance of Urban Search and Rescue Robots

May 17, 2007
Author(s)
Elena R. Messina, Adam S. Jacoff
The Department of Homeland Security is sponsoring development of standards for urban search and rescue (USAR) robots. This program is being coordinated by the National Institute of Standards and Technology and will result in consensus standards developed

A Smart Transducer Interface Standard for Sensors and Actuators

January 1, 2004
Author(s)
Kang B. Lee
A set of common transducer interfaces has been defined in the family of IEEE 1451, standards for connecting sensors and actuators to microprocessors, control and field networks, and instrumentation systems. The standards also defined the Trans-ducer

Diffusion Barrier Cladding in Si/SiGe Resonant Interband Tunneling Diodes and Their Patterned Growth on PMOS Source/Drain Regions

January 1, 2003
Author(s)
N Jin, A T. Rice, P R. Berger, P E. Thompson, C Rivas, R Lake, S Sudirgo, J J. Kempisty, B Curanovic, S L. Rommel, K D. Hirschman, S K. Kurinec, P Chi, David S. Simons, S.J. Chung
Si/SiGe resonant interband tunnel diodes (RITD) employing delta-doping spikes that demonstrate negative differential resistance (NDR) at room temperature are presented. Efforts have focused on improving the tunnel diode peak-to-valley current ratio (PVCR)

The Environmental Life Cycle

October 1, 2002
Author(s)
Barbara C. Lippiatt
ES (Building for Environmental and Economic Sustainability) implements a rational, systematic technique for selecting environmentally and economically balanced building products. The technique is based on consensus standards and designed to be practical

Design of an Active MM-Wave Concealed Object Imaging System

August 1, 2001
Author(s)
Nicholas Paulter, Erich N. Grossman, Gerard N. Stenbakken, Bryan C. Waltrip, Shalva Nolen, Carl D. Reintsema
The research and design of an active millimeter-wave concealed object imaging system is described. Several illumination and detection methods were analyzed via computer simulation to assess the effects of system parameters on the signal-to-noise ratio of

New NIST Mercury Triple-Point Cells

June 1, 2001
Author(s)
Gregory F. Strouse, J Lippiatt
Six new Hg triple-point (TP) cells (234.3156 K) were manufactured in the NIST PRT Laboratory for use in the realization of the International Temperature Scale of 1990 (ITS90). The fixed-point cells consisted of both glass and stainless steel designs with

Performance of a Commerical Hot Water Boiler

November 1, 1998
Author(s)
Cheol D. Park, S T. Liu
In responding to ASHRAE SPC 155P's interest and to provide additional evidence on the envisioned linear relationship between output and input of a boiler under part load conditions, the National Institute of Standards and Technology undertook to conduct a

NIST/NBS Fire Research and FRCA: 25 Years of Progress

April 16, 1998
Author(s)
Richard G. Gann
The National Bureau of Standards' Center for Fire Research and the Fire Retardant Chemicals Association were formed within a year of each other. The former has undergone major organizational changes, NBS having become NIST, and fire research now being part
