TreeDec: An Annotation Tool to Support Website Navigation

July 1, 2002
Author(s)
John V. Cugini
Websites are often organized into logical hierarchies, or tree structures, in order to help users navigate. Ideally, users could view the entire tree, or jump to nearby pages. TreeDec (= Tree Decorator) is a system to support website authors and

Two-dimensional Simulation Modeling in Imaging and Metrology Research

July 1, 2002
Author(s)
Michael T. Postek, Andras Vladar, J R. Lowney, William J. Keery
Traditional Monte Carlo modeling of the electron beam-specimen interactions in a scanning electron microscope (SEM) produces information about electron beam penetration and output signal generation at either a single beam-landing location, or multiple

Use of Thermodynamic Software in Process Modelling and New Applications of Thermodynamic

July 1, 2002
Author(s)
Ursula R. Kattner, G Eriksson, I Hahn, R Schmid-fetzer, Bo Sundman, V Swamy, A Kussmaul, P J. Spencer, T J. Anderson, T G. Chart, A Costa e Silva, B Jansson, B J. Lee, M Schalin
The strongly related nature of the topics allocated to Groups 4 and 5 was such that a close interaction between the two groups appeared essential at all stages of the discussions and for this reason the groups amalgamated. A joint decision was made as to

Working Group on Atomic Transition Probabilities

July 1, 2002
Author(s)
Wolfgang L. Wiese, Jeffrey R. Fuhr
A literature survey of experimental and theoretical work on atomic transition probabilities of astrophysical interest published during the last 3 years is presented. The important literature references, identified by a running number, are collected by

Worldwide Comparisons of Rockwell Hardness Scales that Use a Diamond Indenter

July 1, 2002
Author(s)
Samuel R. Low III, Jun-Feng Song
The United States has participated in two major worldwide comparisons of Rockwell hardness scales over the past twenty years. In 1983, fourteen countries participated in a comparison of the Rockwell C scale. The latest worldwide comparison was completed in

Gas-Phase Mechanisms of Fire Retardants

June 28, 2002
Author(s)
Gregory T. Linteris
Fire retardants are added to polymers to increase their ignition time and reduce their heat release rates when burning. They are often described as acting either in the condensed-phase or in the gas-phase, with an understanding that often, both modes can

Quantum Computing and Communication

June 28, 2002
Author(s)
Paul E. Black, David R. Kuhn, Carl J. Williams
A quantum computer, if built, will be to an ordinary computer as a hydrogen bomb is to gunpowder, at least for some types of computations. Today no quantum computer exists, beyond laboratory prototypes capable of solving only tiny problems, and many

Controlled Barrier Modification in Nb/NbOx/Ag Metal Insulator Metal Tunnel Diodes

June 15, 2002
Author(s)
Erich N. Grossman, Todd E. Harvey, Carl D. Reintsema
The nonlinear electrical transport properties of metal-insulator-metal (MIM) tunnel diodes based on a barrier of naturally grown niobium oxide have been measured at room temperature and analyzed. In most cases excellent agreement is found between the

A Macro-Micro Motion System for a STM

June 13, 2002
Author(s)
Bradley N. Damazo, James D. Gilsinn, Richard M. Silver, Hui Zhou
As nano-lithography improves, more companies and research groups have the capability to create nano-scale structures. Scanning Tunneling Microscopes (STMs) are commonly used to create these structures and evaluate them afterward. One difficulty is that

Evaluation of Component-Based Reconfigurable Machine Controllers

June 13, 2002
Author(s)
S Kolla, John L. Michaloski, William G. Rippey
The lack of interoperability and integration standards is severely hindering manufacturing productivity. To address this problem, a General Motion Control (GMC) Testbed has been developed at National Institute of Standards and Technology (NIST) with one of

Tying Together Design, Process Planning and Machining with Step-NC Technology

June 13, 2002
Author(s)
Frederick M. Proctor, John L. Michaloski, William P. Shackleford
While simulation has been successful in tying design and process planning into an iterative loop, machining has traditionally been a downstream terminus of the manufacturing cycle. Simulation of machining has proven difficult due to the highly dynamic and
