Management Guide to the Protection of Information Resources

October 1, 1989
Author(s)
Cheryl Helsing, Marianne M. Swanson, Mary A. Todd
This guide introduces information systems security concerns and outlines the issues that must be addressed by all agency managers in meeting their responsibilities to protect information systems within their organizations. It describes essential components

Potential energy surface for interactions between two hydrogen molecules

September 4, 2008
Author(s)
Allan H. Harvey, Konrad Patkowski, Wojciech Cencek, Piotr Jankowski, Krzysztof Szalewicz, Giovanni Garberoglio
Nonrelativistic clamped-nuclei energies of interaction between two ground-state hydrogen molecules with intramolecular distances fixed at their average value in the lowest rovibrational state have been computed. The calculations applied the supermolecular

The Language of Tolerances

July 1, 1993
Author(s)
Ted Hopp
Dimensional tolerancing is a language used to communicate product specifications. Effective communication using this language relies on there being a common, shared meaning for tolerances. By this measure, the language relies on there being a common

Prashanth Jaganmohan, Bala Muralikrishnan, Meghan Shilling, Ed Morse
… parts and those with complex internal features, X-ray computed tomography (XCT) has transitioned from a medical … analysis, single-point ray tracing method, X-ray computed tomography … X-ray Computed Tomography Instrument Performance Evaluation, Part …

Real-time Single-workstation Obstacle Avoidance Using Only Wide-field Flow Divergence

January 1, 1999
Author(s)
Theodore(Ted) Camus, David Coombs, Martin Herman, Tsai Hong Hong
This paper describes a real-time robot vision system which uses only the divergence of the optical flow field for both steering control and collision detection. The robot has wandered about the lab at 20 cm/s for as long as 26 minutes without collision

An Attack Graph Based Probabilistic Security Metric

July 16, 2008
Author(s)
Lingyu Wang, Tania Islam, Tao Long, Anoop Singhal, Sushil Jajodia
… cycles and extend the definition accordingly. We show that computing the metric directly from its definition is not …

Obtaining Molecular Thermochemistry From Calculations

September 30, 2007
Author(s)
Karl K. Irikura
There are several computational approaches for predicting gas-phase, molecular thermochemistry. For common organic compounds, empirical methods are quick to compute and have been effectively parameterized. For uncommon compounds, the relative robustness of

Calorimetry in Computed Tomography Beams

Author(s)
Heather H. Chen-Mayer, Ronald Tosh, Fred B. Bateman, Paul Bergstrom, Brian E. Zimmerman
… for direct realization of absorbed dose in medical computed tomography (CT) procedures was constructed and … Calorimetry in Computed Tomography Beams …

A Unique Sensor Fusion System for Coordinate Measuring Machine Tasks

October 1, 1997
Author(s)
M Nashman, Billibon H. Yoshimi, Tsai H. Hong, William G. Rippey, Martin Herman
This paper describes a real-time hierarchical system that combines (fuses) data from vision and touch sensors to simplify and improve the operation of a coordinate measuring machine (CMM) used for dimensional inspection tasks. Our emphasis is on sensory

Digital Investigation Techniques: A NIST Scientific Foundation Review

November 21, 2022
Author(s)
James R. Lyle, Barbara Guttman, John Butler, Kelly Sauerwein, Christina Reed, Corrine Lloyd
This document is an assessment of the scientific foundations of digital forensics. We examined descriptions of digital investigation techniques from peer-reviewed sources, academic and classroom materials, technical guidance from professional organizations

Coating Industry Knowledge Base Systems.

November 17, 1996
Author(s)
S K. Boocock, L J. Kaetzel
This presentation provides information about the proposed SSPC Coatings Knowledge Center and activities of a national program for a computer integrated knowledge systems network administered by the National Institute of Standards and Technology.
