A Step Towards CO2-Neutral Aviation

November 20, 2007
Author(s)
Andreja Brankovic, Robert C. Ryder, Robert C. Hendricks, Marcia L. Huber
An approximation method for evaluation of the caloric equations used in combustion chemistry simulations is described. The method is applied to generate the specific heat, static enthalpy, and Gibb's free energy equations for fuel mixtures of interest to

Overlay Metrology Simulations: Analytical and Experimental Validations

May 1, 2003
Author(s)
Joel L. Seligson, B Golovanevsky, J M. Poplawski, M E. Adel, Richard M. Silver
We have previously reported on an overlay metrology simulation platform, used for modeling both the effects of overlay metrology tool behavior and the impact of target design on the ultimate metrology performance. Since our last report, the simulations by

John A. Tesk, K White
Subcommittee & member actions: H Membership is adjusted for 2003-2004. H Society approval sought for co-sponsorship of a NIST symposium on Cell Signaling. H RM 8457, cubes of Ultrahigh Molecular Weight Polyethylene, will be available after some

A Privilege Management Scheme for Mobile Agent Systems

August 1, 2002
Author(s)
Wayne Jansen
In this paper, we describe a general method for controlling the behavior of mobile agent-system entities through allocation of privileges. Privileges refer to policy rules that govern the access and use of computational resources and services. The scheme

Progress in Developing NIST Standard Casings

January 1, 2002
Author(s)
Jun-Feng Song, Theodore V. Vorburger, M Ols
Standard casings and bullets are currently under development to support the National Integrated Ballistics information Network (NIBIN). The master casings are obtained from the ATF''s National Laboratory Center at Rockville, MD, by a standardized shooting

Determining Privileges of Mobile Agents

January 1, 2001
Author(s)
Wayne Jansen
This paper describes a method for controlling the behavior of mobile agent-system entities through the allocation of privileges. Privileges refer to policy rules that govern the access and use of computational resources and services by mobile agents. Our

Sources of Uncertainty in UV Radiation Measurements

January 1, 2001
Author(s)
Thomas C. Larason, Christopher L. Cromer
Increasing commercial, scientific, and technical applications involving ultraviolet (UV) radiation has led to the demand for improved understanding of the performance of instrumentaion used to measure this radiation. There has been an effort by
