Similarity Based Retrieval from a 3D Human Database

August 1, 2005
Author(s)
Afzal A. Godil, Sanford P. Ressler
In this paper, we describe a framework for similarity based retrieval from a 3D human database. Our technique is based on both body and head shape representation and retrieval based on similarity of both of them. The 3D human database used in our study is

Shirley M. Radack
This bulletin describes the NIST security configuration checklists program and is based on NIST Special Publication 800-70: Security Configuration Checklists Program for IT Products, by Murugiah Souppaya, John Wack and Karen Kent. The bulletin discusses

Network Transfer of Control Data: An Application of the NIST Smart Data Flow

April 15, 2005
Author(s)
Martial Michel, Vincent M. Stanford, O P. Galibert
Pervasive Computing environments range from basic mobile point of sale terminal systems, to rich Smart Spaces with many devices and sensors such as lapel microphones, audio and video sensor arrays and multiple interactive PDA acting as electronic brief

A Numerical Method for Mass Spectral Data Analysis

January 31, 2005
Author(s)
Anthony J. Kearsley, William E. Wallace, Javier Bernal, Charles M. Guttman
The new generation of mass spectrometers produces an astonishing amount of high-quality data in a brief period of time leading to inevitable data analysis bottlenecks. Automated data analysis algorithms are required for rapid and repeatable processing of

Toward a Formal Common Information Model Ontology

November 1, 2004
Author(s)
Stephen Quirolgico, P Assis, A Westerinen, M Baskey, E Stokes
We examine the performance of multimodal biometric authentication systems using state-of-the-art Commercial Off-the-Shelf (COTS) fingerprint and face biometric systems on a population approaching 1,000 individuals. Majority of prior studies of multimodal

Feasibility Study for the Development of a Motion Imagery Quality Metric

October 1, 2004
Author(s)
J Irvine, Charles D. Fenimore, D Cannon, John W. Roberts, S Israel, L Simon, C Watts, J Miller, A I. Aviles, P F. Tighe, R J. Behrens
The motion imagery community would benefit from the availability of standard measures for assessing image interpretability. The National Imagery Interpretability Rating Scale (NIIRS) has served as a community standard for still imagery, but no comparable

From Databooks to Online Dictionaries and Parts Catalogues

Author(s)
John V. Messina, James A. St Pierre
This power point presentation was presented at the 4th Annual ECCMA Membership Conference at Lehigh University on October 22nd, 2003 during a panel presentation on competitive sourcing, parts interoperability, and inventory visibility in public sector

Thirteenth International Conference on Computer Technology in Welding

October 1, 2003
Author(s)
Thomas A. Siewert, William G. Rippey
The Thirteenth International Conference on Computer Technology in Welding was held June 18, 2003 in Orlando, Florida, under the sponsorship of the American Welding Society, the National Institute of Standards and Technology (NIST), and The Welding Institue

Building a Filtering Test Collection for TREC 2002

July 28, 2003
Author(s)
Ian M. Soboroff, S E. Robertson
Test collections for the filtering track in TREC have typically used either past sets of relevance judgments, or categorized collections such as Reuters Corpus Volume 1 or OHSUMED, because filtering systems need relevance judgments during the experiment

Interface-Driven Model-Based Generation of Java Test Drivers

September 3, 2002
Author(s)
Mark Blackburn, Robert Busser, Aaron Nauman, Ramaswamy Chandramouli
This paper extends prior work in model-based verification and describes interface-driven analysis that combines with a requirement model to support automated generation of Java test scripts. It describes concepts of models and test driver mappings using

A New Classification of Information: A Step on the Road to Interpretability

September 1, 2002
Author(s)
Larry H. Reeker, Albert W. Jones
Complex systems, such as manufacturing supply chains, are often modeled as a collection of interacting components with information flows between them. These components are frequently responsible for making a wide range of decisions that are implemented

Measuring the Impact of Information on Complex Systems

June 1, 2002
Author(s)
Larry H. Reeker, Albert W. Jones
The application of power-driven machinery to manufacturing and other areas of human endeavor characterized the Industrial Revolution in the 18th and 19th centuries. Measurement contributed in many ways to the increasing economic influence of these machines

Accelerating Scientific Discovery through Computation and Visualization II

May 1, 2002
Author(s)
James S. Sims, William L. George, Steven G. Satterfield, Howard Hung, John G. Hagedorn, Peter M. Ketcham, Terence J. Griffin
This is the second in a series of articles describing a wide variety of projects at NIST that synergistically combine physical science and information science. It describes, through examples, how the Scientific Applications and Visualization Group (SAVG)

The NIST Electron Effective-Attenuation-Length Database

February 1, 2002
Author(s)
Cedric J. Powell, Aleksander Jablonski
The NIST Electron Effective-Attenuation-Length Database provides values of electron effective attenuation lengths (EALs) in solid elements and compounds at selected electron energies between 50 eV and 2,000 eV. The database was designed mainly to provide

Measurement of Dynamic Properties in Thin-Films

December 1, 2001
Author(s)
Thomas J. Silva
I present a summary of the various techniques available for the determination of response times in magnetic recording head materials. In addition, I derive useful equations for the interpretation of data in the context of the Landau-Lifshitz-Gilbert
