Information Access: Do You Mind?

September 1, 2002
Author(s)
John V. Cugini
Successful execution of many information-based tasks depends crucially on contextual knowledge. Language processing is particularly sensitive to context, and I will concentrate on it in this extended abstract as the example par excellence of knowledge

Technical Digest Symposium on Optical Fiber Measurements, 2002

September 1, 2002
Author(s)
Paul A. Williams, Gordon W. Day
This digest contains the papers presented at the 2002 Symposium on Optical Fiber Measurements, a 2-1/2 day forum devoted to measurements of fibers, integrated optics, components and systems. Topics covered include measurement of polarization-mode

About Substitution for Ozone-Depleting Agents for Fire Extinguishing

June 1, 2002
Author(s)
A N. Baratov, N P. Kopylov, E V. Timofeev
New ozone-friendly fire extinguishing mixtures based on iodinated halons are proposed in the present paper. They act on a flame both chemical inhibitor and diluent. It was obtained that mixture CF3H+CH3I has value of minimum fire extinguishing

Discharge of CF3I in a Cold Simulated Aircraft Engine Nacelle (NIST SP 984)

June 1, 2002
Author(s)
Jiann C. Yang, Samuel L. Manzello, Marc R. Nyden, M D. Connaghan
An aircraft engine nacelle refers to the region between the engine body and its casing. Fuel and hydraulic lines, pumps, and lubrication systems are located within the nacelle. Air is vented through the nacelle to prevent any build-up of combustible vapors

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

Proceedings of the 12th Halon Options Technical Working Conference

June 1, 2002
Author(s)
Richard G. Gann
This proceedings contains the papers from the 12th Halon Options Technical Working Conference. The topics covered include: results from the DoD Next Generation Fire Suppression Technology Program, total flood applications, passive fire protection

NIST Standard Reference Materials Catalog 2002

February 1, 2002
Author(s)
J W. Thomas
This catalog provides technical and general ordering information for the Standard Reference Materials [SRMs] and Reference Materials [RMs] currently available from the NIST SRM Program. The materials are arranged according to technical category and

Eleventh International Conference on Computer Technology in Welding

January 1, 2002
Author(s)
Thomas A. Siewert, C Pollock
These are proceedings of the eleventh conference in this series. The conference was held December 5 and 6, 2001, in Columbus, Ohio, under the sponsorship of the American Welding Society, NIST, and The proceedings include 32 presentations grouped into

Enhanced Powder Panels

January 1, 2002
Author(s)
D C. Cyphers, Scott A. Frederick, John P. Haas
Ballistic threat-induced fires are a major contributor to aircraft vulnerability. This paper describes a recent investigation of new concepts for powder panels, an old alternative for discharging dry chemical agents to extinguish combat-induced fires in

Fluoroalkyl Phosphorus Fire Extinguishing Agents

January 1, 2002
Author(s)
R E. Tapscott, J M. Shreeve, J D. Mather
Phosphorus compounds show extraordinary effectiveness as flame extinguishants, and there is evidence for a chemical mechanism. Most work to date, however, has emphasized alkyl phosphonates and related materials or phosphonitriles. The former compounds are

INTUMESCENT INSTANT FIREWALLS FOR LOW-COST FIRE PROTECTION

January 1, 2002
Author(s)
Ginger Bennett
Intumescent materials respond to impingement of a fire by swelling and forming a protective char that physically and thermally protects the structure. Intumescent materials have been used (or investigated for use) in various military platforms for all

LIQUID AGENT TRANSPORT AROUND SOLID OBSTACLES

January 1, 2002
Author(s)
Cary Presser, J F. Widmann, G Papadopoulos
The focus of this effort is to investigate the dispersal of liquid fire suppression agents around solid obstacles, and obtain a better understanding of the physical processes of droplet transport in cluttered spaces. An experimental investigation is
