Concrete Materials Database

December 1, 2000
Author(s)
C B. Oland, Chiara C. Ferraris
ACI Committee 126 on Database Formats for Concrete Materials Properties was organized in 1990 to develop and report information on database formats for concrete and related materials. The committee is accomplishing this mission by preparing guides for use

Automated Part Tracking on the Construction Job Site

July 1, 2000
Author(s)
William C. Stone, L E. Pfeffer, K M. Furlani
Efforts are underway at the National Institute of Standards and Technology (NIST) to develop a web-based system for rapid tracking, identifying, and locating manufactured components on the construction jobsite. The approach involves the use of RFID and

Solidification Microstructures: Recent Developments, Future Directions

January 1, 2000
Author(s)
William J. Boettinger, Sam R. Coriell, A L. Greer, A N. Karma, W Kurz, M Rappaz, R Trivedi
This review is intended to critically evaluate the latest status of solidification science and to discuss and propose future directions of research in this technologically important area. It is an updated version of the outcome of the 1998 Zermatt Workshop

The NIST DMIS Interpreter: Version 2

October 1, 1998
Author(s)
Thomas R. Kramer, Frederick M. Proctor, William G. Rippey, Harry A. Scott
This report describes an interpreter which reads a file of numerical control code for a coordinate measuring machine (CMM), produces calls to a set of canonical CMM functions, and writes inspection report files. The interpreter is a software system written

High-Resolution, Energy-Dispersive Microcalorimeter Spectrometer for X-Ray Microanalysis

December 1, 1997
Author(s)
David A. Wollman, Kent D. Irwin, Gene C. Hilton, L L. Dulcie, Dale E. Newbury, John M. Martinis
We have developed a prototype X‐ray microcalorimeter spectrometer with high energy resolution for use in X‐ray microanalysis. The microcalorimeter spectrometer system consists of a superconducting transition‐edge sensor X‐ray microcalorimeter cooled to an

A Parametric Representation of Fuzzy Numbers and Their Arithmetic Operators

September 1, 1997
Author(s)
Ronald Giachetti
Direct implementation of extended arithmetic operators on fuzzy numbers is computationally complex. Implementation of the extension principle is equivalent to solving a nonlinear programming problem. To overcome this difficulty many applications limit the

Effect of Sample Size on the Heat Release Rate of Charring Materials

March 3, 1997
Author(s)
S J. Ritchie, Kenneth D. Steckler, Anthony P. Hamins, Thomas G. Cleary, Jiann C. Yang, Takashi Kashiwagi
The burning of a horizontal wood slab situated atop an insulating substrate was modeled using three coupled submodels for the gas-phase, wood, and substrate processes. A global analytical model was used to determine the radiative and convective heat

Radiometric Model of the Transmission Cell-Reciprocal Nephelometer

January 1, 1994
Author(s)
George W. Mulholland, Nelson P. Bryner
A radiometric model has been developed to assess the effects of angular truncation, finite size of the detector, and angle response characteristics of the cosine sensor on the measurement of the total scattering coefficient by a transmission cell

Calculations of Electron Inelastic Mean Free Paths (IMFPs) IV. Evaluation of Calculated IMFPs and of the Predictive IMFP Formula Tpp-2 for Electron Energies between 50 and 2000 eV

January 1, 1993
Author(s)
Shigeo Tanuma, Cedric J. Powell, David R. Penn
We have made additional evaluations of the electron inelastic mean free paths (IMFPs) and of the predictive IMFP formula TPP-2 presented in papers II and III of this series. Comparisons have been made with other formulae for the IMFPs and electron

Fire Performance of Interstitial Space Construction Systems.

May 1, 1985
Author(s)
James R. Lawson
Two unique walk-on deck construction systems were exposed to the standard NFPA 251 time-temperature fire exposure for periods up to two hours in order to evaluate their fire performance. A large scale steel structure was used in the test program to

Cost-Conscious Guide to Fire Safety in Health Care Facilities.

November 1, 1982
Author(s)
Robert E. Chapman
This study focuses upon the use of the Fire Safety Evaluation System developed by the Center for Fire Research at the National Bureau of Standards for determining equivalence to the Life Safety Code for health care facilities. The Life Safety Code, a

The Virtual Manufacturing Cell

October 1, 1982
Author(s)
Charles R. McLean, Howard Bloom, Ted Hopp
A virtual manufacturing cell is being developed at the National Bureau of Standards as part of the control software for the Automated Manufacturing Research Facility (AMRF) project. The traditional group technology (GT) cell has evolved from the need to
