Experiments toward Non-contact Safety Standards for Automated Industrial Vehicles

June 28, 2006
Author(s)
Roger V. Bostelman, Tsai Hong Hong, Rajmohan Madhavan
The performance evaluation of an obstacle detection and segmentation algorithm is explained upon comparing a new range camera to ground truth. Automated Guided Vehicles (AGVs) in factory-like environments may one day utilize this algorithm for advanced

Selecting Effective Test Messages

June 1, 2006
Author(s)
Leonard E. Gebase, Roch Bertucat, Robert D. Snelick
One of the first problems that must be addressed when attempting to test the reliability of any software implementation is determining what is to be tested. The number of paths an implementation can follow is generally much too large to be able to test all

Fire Tests of Single Office Workstations. Federal Building and Fire Safety Investigation of the World Trade Center Disaster (NIST NCSTAR 1-5C) ***DRAFT for Public Comments***

September 1, 2005
Author(s)
Thomas J. Ohlemiller, George W. Mulholland, Skandakumar H. Abeyesekere, James J. Filliben, Richard G. Gann
Reconstruction of the fires that occurred in the World Trade Center (WTC) 1, 2, and 7 on September 11. 2001, relied heavily on computer simulations because examination of the post-fire premises was not possible and the information from eyewitness accounts

Analysis and Evaluation for STEP-Based Electro-Mechanical Assemblies

August 1, 2005
Author(s)
XuanFang Zha, Sebti Foufou, Sudarsan Rachuri, Ram D. Sriram
In this paper, we propose an integrated approach to assemblability analysis and evaluation for STEP-based (STandard for the Exchange of Product model data, officially ISO 10303) electro-mechanical products. First, two assembly representational models are

Vapour Pressure of Diethyl Phthalate

September 11, 2004
Author(s)
Vladimir Rohac, Kvetoslav Ruzicka, Vlastimil Ruzicka, Dzmitry H. Zaitsau, Gennady J. Kabo, Vladimir Diky, Karel Aim
Measurements of vapour pressure in the liquid phase and of enthalpy of vaporisation and results of calculation of ideal gas properties for diethyl phthalate are reported. The method of comparative ebulliometry, the static method, and the Knudsen mass loss

Backup Resource Pooling in (M : N) n Fault Recovery Schemes in GMPLS Optical Networks

October 1, 2003
Author(s)
Kotikalapudi Sriram, David W. Griffith, San-Nan K. Lee, Nada T. Golmie
In resilient optical networks, there is a tradeoff between the amount of resources allocated for protection versus the probability that a failed working path cannot be covered, known as protection blocking probability. Often the network topology permits

Line Assignments and Global Analysis of the Tunneling-Rotational Microwave Absorption Spectrum of Dimethyl Methylphosphonate

March 1, 2003
Author(s)
N Ohashi, J Pyka, G Y. Golubiatnikow, Jon T. Hougen, R D. Suenram, Francis J. Lovas, A Lesarri, Y Kawashima
Line assignments were carried out for about 600 Fourier transform microwave transitions for dimethyl methylphosphonate involving levels of all six symmetry species in the G 18 molecular symmetry group appropriate for three large-amplitude motions and

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

Cryptographic Standards and Guidance: A Status Report

September 1, 2002
Author(s)
Elaine B. Barker
A comprehensive toolkit of cryptographic standards and associated guideline that covers a wide range of cryptographic technology is currently under development by the Computer Security Division at NIST. These standards and guidelines will enable U.S

Fabricating Planar Nanoparticle Assemblies With Number Density Gradients

July 1, 2002
Author(s)
R R. Bhat, Daniel A. Fischer, Jan Genzer
We report on preparing assemblies of gold nanoparticles with continuous gradients in number density on flat silica-covered substrates. The methodology consists of: i) first forming a one dimensional molecular gradient of amino groups (-NH2) on the

Calibration of a Heat Flux Sensor Up to 200 kW/m 2 in a Spherical Blackbody Cavity

January 1, 2002
Author(s)
A V. Murthy, Benjamin K. Tsai, Robert D. Saunders
This paper presents the results of a comparative study of narrow view-angle and wide view-angle calibrations of a water-cooled Schmidt-Boelter heat-flux sensor. The narrow view-angle calibration, up to a heat flux level of 50 kW/m2, was conducted using the

Special Issue - Crystallography at NIST/NBS

December 1, 2001
Author(s)
Alan D. Mighell, Winnie K. Wong-Ng
The Centennial Celebration of the National Institute of Standards and Technology (NIST), formerly known as the National Bureau of Standards (NBS), takes place in the year 2001. NIST has a long history (> 50 years) of crystallographic research, and has made

Transition Probabilities and Atomic Lifetimes

February 1, 2001
Author(s)
Wolfgang L. Wiese
The Data Center on Atomic Transition Probabilities at the U.S. National Institute of Standards and Technology (NIST), formerly the National Bureau of Standards (NBS), has critically evaluated and compiled atomic transition probability data since 1962 and

Definitions of Terms and Modes Used at NIST for Value-Assignment of Reference Materials for Chemical Measurements

January 1, 2000
Author(s)
Willie E. May, Reenie M. Parris, C M. Beck, John D. Fassett, Robert R. Greenberg, Franklin R. Guenther, Gary W. Kramer, Stephen Wise, T E. Gills, Jennifer C. Colbert, R J. Gettings, Bruce S. MacDonald
Standard Reference Materials (SRMs) are certified reference materials (CRMs) issued by NIST that are well-characterized using state-of-the-art measurement methods and/or techniques for the determination of chemical compositon and physical properties. SRMs

Minimizing Throttline Losses in the Refrigeration Cycle

August 1, 1995
Author(s)
Piotr A. Domanski
Most alternative non-CFC refrigerants have a large molecular structure and large heat capacity, which influence the slope of saturated liquid line and result in substantial throttling losses in a basic reversed Rankine cycle. These losses degrade the cycle

Canadian Mass Fire Experiment, 1989.

November 1, 1990
Author(s)
J G. Quintiere
Working with Forestry Canada and the Ontario Ministry of Natural Resources, the Defense Nuclear Agency carried out an extensively instrumented experiment of a prescribed burn in forest debris to simulate conditions of a mass fire. In addition to the

Inferring previously uninstalled applications from digital traces

May 25, 2017
Author(s)
Jim Jones, Tahir Kahn, Kathryn B. Laskey, Alexander J. Nelson, Mary T. Laamanen, Douglas R. White
In this paper, we present an approach and experimental results to suggest the past presence of an application after the application has been uninstalled and the system has remained in use. Current techniques rely on the recovery of intact artifacts and
