Prototype Methodology for Fire Hazard Analysis

February 1, 1990
Author(s)
Richard D. Peacock, Richard W. Bukowski
The first version of a method for predicting the hazards to occupants involved in a building fire is described. The method and available computer software, called HAZARD I, can predict the time varying environment within a building resulting from a

The NIST PDES Toolkit: Technical Fundamentals

February 1, 1990
Author(s)
Steve Clark
The NIST PDES Toolkit provides a set of software tools for manipulating Express information models and STEP product models. It is a research-oriented toolkit, intended for use in a research and testing environment. This document gives a technical

A method for the synthesis of bi- , tri- and tetracyclic hydrocarbons with five membered rings

January 29, 1990
Author(s)
Anzor Mikaia, Anton Shuikin, Leonid S. Glebov, Alexey Yatsenko, Vladimir G. Zaikin, George A. Kliger, Sergai Loktev
Reaction gas chromatography-mass spectrometry is applied to establish optimal conditions for the synthesis of bi- , tri- and tetracyclic hydrocarbons with five membered rings. Further optimization of the reaction was carried out in a pilot plant.

Current supply for high-Tc superconductor testing

January 18, 1990
Author(s)
Loren F. Goodrich, S L. Bray
Precise and accurate measurements of the DC critical current of high-Tc superconductors often require a current supply that has high input-to-output isolation, high isolation from ground and low output ripple. Also, to ensure precise current control, the

High Tc superconductors and critical current measurement*

January 17, 1990
Author(s)
Loren F. Goodrich, S L. Bray
With the introduction of high Tc superconductors, a number of problems associated with critical current, Ic, measurement have arisen. THe existing Ic measurement practices were developed and proved for low Tc superconductors. There are substantial

AI in Manufacturing: The NBS AMRF as an Intelligent Machine

January 2, 1990
Author(s)
Dennis A. Swyt
Within its Automated Manufacturing Research Facility (AMRF), the U.S. National Bureau of Standards (NBS) is addressing research issues in interface standards for the fully automated factory of the future for the production of small batches of discrete
