Uncertainty in NIST Force Measurements

December 1, 2005
Author(s)
Thomas W. Bartel
This paper focuses upon the uncertainty of force calibration measurements at the National Institute of Standards and Technology (NIST). The uncertainty of the realization of force for the national deadweight force standards at NIST is discussed, as well

Viscosity

December 1, 2005
Author(s)
Robert F. Berg
This article summarizes the role of viscosity in describing the properties and flow of fluids. Its measurement, dependences on temperature and density, and deviations from Newtonian behavior are discussed. Example plots and a bibliography are included.

Visual Evidence, Damage Estimates, and Timeline Analysis (Appendices D-G) Federal Building and Fire Safety Investigation of the World Trade Center Disaster (NIST NCSTAR 1-5A)

December 1, 2005
Author(s)
William M. Pitts, Kathryn M. Butler, Valentine Junker
This report summarizes the collection and analysis of visual material used for the National Institute of Standards and Technology (NIST) World Trade Center (WTC) Investigation. The task consisted of four major subtasks: 1) identification, collection, data

Wavelength references for interferometry in air

December 1, 2005
Author(s)
R W. Fox, Brian R. Washburn, Nathan R. Newbury, Leo W. Hollberg
Cavity-mode wavelengths in air are determined by measuring a laser's fequency while it is locked to the mode in vacuum during a caibration step and subsequently correcting the mode wavelength for atmospheric pressure compression, temperature difference

What a User Should Know When Selecting an Evacuation Model.

December 1, 2005
Author(s)
Erica D. Kuligowski, Steve M. Gwynne
In recent years, evacuation models have been increasingly applied in an attempt to understand the outcome of emergency egress scenarios. This has been due to the increased use of performance-based design and the availability of cost-effective, high

Temporal Range Registration for Unmanned Ground and Aerial Vehicles

November 30, 2005
Author(s)
Rajmohan (. Madhavan, Tsai H. Hong, Elena R. Messina
An iterative temporal registration algorithm is presented in this article for registering 8 3D range images obtained from unmanned ground and aerial vehicles traversing unstructured 9 environments. We are primarily motivated by the development of 3D

Towards the Design of Effective Formative Test Reports

November 30, 2005
Author(s)
Mary F. Theofanos, Whitney Quesenbery
Many usability practitioners conduct most of their usability evaluations to improve a product during its design and development. We call these "formative" evaluations to distinguish them from "summative" (validation) usability tests at the end of
