Can a Pressure Standard be Based on Capacitance Measurements?

March 1, 1998
Author(s)
Michael R. Moldover
We consider the feasibility of basing a pressure standard on measurements of the dielectric constant [epsilon] and the thermodynamic temperature T of helium near )[degrees]C. The pressure P of the helium would be calculated using the fundamental constants

Cement Hydration in the Presence of Municipal Solid Waste Incineration of Fly Ash

March 1, 1998
Author(s)
S J. Remond, Dale P. Bentz, M. Pimpinella, J P. Bournazel
This study is part of a wider research program aimed at developing an assessment methodology of waste-containing concrete. This methodology is developed based on the study of mortars containing an experimental waste: MSWIFA (Municipal Solid Waste

Concrete: A Multi-Scale Interactive Composite

March 1, 1998
Author(s)
Edward J. Garboczi, Dale P. Bentz
Methods have been developed for predicting the overall diffusion coefficient of ions in concrete using a multi-scale interactive analysis, ignoring any chloride binding interactions. The analysis makes use of microstructure models of mortar/concrete and

Dynamic and Static Grain Growth During the Superplastic Deformation of 3Y-TZP

March 1, 1998
Author(s)
J Seidensticker, M J. Mayo
While phenomenological theories of superplasticity have often suffered from the fact that a single phenomenological law is not universally applicable to all superplastic systems, it is shown that a universal dynamic grain growth law does apply. The law is

Fourth International Symposium on Roofing Technology

March 1, 1998
Author(s)
Walter J. Rossiter Jr
This report presents a summary of the Fourth International Symposium on Roofing Technology. The National Institute of Standards and Technology (NIST) Building and Fire Research Laboratory (BFRL) and the National Roofing Contractors Association (NRCA) have

Hyperfine Structure Constants for Diatomic Molecules

March 1, 1998
Author(s)
I Tupitsyn, Svetlana A. Kotochigova
The contact term A c of magnetic hyperfine parameters as a function of internuclear distance R was computed, using the all-electron Valence-Bond method, Hartzee-Fock atomic basis set and configuration-interaction wave functions. Parameters were calculated

Integration Strategies for the Reactive Scheduling System

March 1, 1998
Author(s)
David W. Thomas
Shop Floor operations can be optimized by scheduling applications that not only create an initial schedule but also allow feedback from data collection systems to enable re-scheduling. Interfaces required to integrate the various commercial applications
