Converting System Failure Histories Into Future Win Situations

January 7, 2000
Author(s)
D Wallace, David R. Kuhn
Most complex systems today contain software, and systems failures activated by software faults can provide lessons for software development practices and software quality assurance. This paper presents an analysis of software-related failures of medical

A User's Guide for FAST: Engineering Tools for Estimating Fire Growth and Smoke Transport

January 3, 2000
Author(s)
Richard D. Peacock, Paul A. Reneke, Walter W. Jones, Richard W. Bukowski, Glenn P. Forney
FAST is a collection of fire modeling tools which uses the underlying fire model CFAST and adds the routines of FIREFORM to provide engineering calculations of fire phenomena in compartmented structures. This manual provides documentation and examples for

Electricity Division Programs, Activities, and Accomplishments

January 2, 2000
Author(s)
B. F. Field
The Electricity Division maintains and disseminates the national standards of electrical measurement and develops the measurement methods and services needed to support electrical materials, components, instruments, and systems used for the generation

A Bandwidth Guaranteed Multi-Access Protocol for WDM Local Networks

January 1, 2000
Author(s)
J S. Choi, Nada T. Golmie, David H. Su
In this paper, we propose a bandwidth guaranteed multi-access protocol for broadcast-and-select WDM local networks with a star topology. The proposed protocol is based on a combination of contention and reservation mechanisms for time slotted WDM networks

A Comparison of Aluminum Nitride Freely Nucleated and Seeded on 6H-Silicon Carbide

January 1, 2000
Author(s)
J H. Edgar, Larry Robins, S E. Coatney, L Liu, J Chaudhuri, K Ignatiev, Z J. Rek
The crystal structure and optical properties of AlN single crystals prepared by the sublimation-recondensation method were analyzed by cathodoluminescence (CL) spectroscopy, Raman spectroscopy, and synchrotron white-beam x-ray topography (SWBXT). Needles

A Comparison of ITS-90, Above the Silver Point, as Realised by NIST and NPL

January 1, 2000
Author(s)
Graham Machin, Charles E. Gibson, B. Carol Johnson, Howard Yoon
A comparison of the radiance temperature scales between 1000 C and 2700 C has been performed between the National Physical Laboratory (NPL) and the National Institute of Standards and Technology (NIST). Two transfer radiation thermometers, of identical

A Conceptual Model for Pervasive Computing

January 1, 2000
Author(s)
L P. Ciarletta, Alden A. Dima
As an emerging field, pervasive computing has not had the opportunity to develop a conceptual model similar to the OSI Reference Model used to describe computer networks. Such a model would be useful to properly classify issues raised during discussion and

A Fast Algorithm for Determining the Gaussian Filter Mean Line in Surface Metrology

January 1, 2000
Author(s)
Y B. Yuan, X F. Qiang, Jun-Feng Song, Theodore V. Vorburger
A fast algorithm for assessing the Gaussian filtered mean line was deduced using the central limit theorem and an approximation method. This algorithm only uses simple computer operations such as addition, subtraction and digit shifting, and avoids
