Collected Publications Related to the Use of Elevators During Fires

May 1, 2002
Author(s)
Richard W. Bukowski, Star R. Burgess, Paul A. Reneke
In the wake of the September 11 attacks in the US provisions for emergency egress from tall buildings are being re-examined, worldwide. Possibilities being discussed include the utilization of protected elevators with stairways for both occupant egress and

Control Strategies for APACTS Micro-Macro-Manipulator-Integration

May 1, 2002
Author(s)
Richard J. Norcross
The Carderock Division of the Naval Surface Warfare Center is developing the Automated Paint Application, Containment, and Treatment System (APACTS). APACTS will apply anti-corrosive and anti-fouling paints to ship hulls in an environmentally sound manner

Cracking in Ceramic/Metal/Polymer Trilayer Systems

May 1, 2002
Author(s)
H Zhao, P Miranda, Brian R. Lawn, X Z. Hu
Fracture and deformation in model brittle-outerlayer/metal-core/polymer substrate trilayer systems in concentrated loading are studied. Model systems for experimental study are fabricated from glass microscope slides glued with epoxy adhesive onto steel

Domain-engineered ferroelectric-pyroelectric detectors for laser metrology

May 1, 2002
Author(s)
John H. Lehman, Harald Gnewuch, Chris Pannell
Ferroelectric pyroelectric detectors are presently used for high accuracy laser metrology. We investigate ways to exploit domain-engineered ferroelectric material such as lithium tantalate to make improved detectors, while understanding changes in the

Dose Meter Calibration System for 193 nm

May 1, 2002
Author(s)
Holger Laabs, Richard D. Jones, Marla L. Dowell
We have established a measurement system for the direct calibration of energy density (dose) meters. It consists of beam-shaping objects, a beamsplitter, calibrated apertures, a beam profile monitor, an energy monitor, and a transfer standard. The 193 nm

Dynamic Expansion of M:N Protection Groups in GMPLS Optical Networks

May 1, 2002
Author(s)
David W. Griffith, Sanghun Lee
In order to provide reliable connections across metropolitan and wide-area optical networks, the network operator must provide some degree of redundancy so that traffic can be switched from damaged working paths to backup paths that are disjoint from the

Effect of Counterface Roughness on Abrasive Wear of Hydroxyapatite

May 1, 2002
Author(s)
Sergei Kalinin, S Jahanmir, L K. Ives
The present study was undertaken to evaluate the effect of surface roughness of glass-infiltrated alumina on the abrasive wear of hydroxyapatite using a pin-on-disk tribometer. Hydroxyapatite was used as a model material to simulate tooth enamel. The wear

Effective Non-Toxic Metallic Fire Suppressants. Final Report (NISTIR 6875)

May 1, 2002
Author(s)
Gregory T. Linteris, M D. Rumminger, Valeri I. Babushok, H K. Chelliah, T Lazzarini, P N. Wanigarathne
The purpose of the project was to: a.) identify which metal species would be effective flame inhibitors, and then b.) attempt to find non-toxic forms of the metal which could be used. Very early in the project, however, we determined that metal species-in

Evaluating Building Integrated Photovoltaic Performance Models

May 1, 2002
Author(s)
Arthur H. Fanney, Brian P. Dougherty, Mark W. Davis
Predictive performance tools could accelerate the implementation of integrated photovoltaics (BIPV. The National Institute of Standards and Technology (NIST) seeks to improve and validate previously developed computer simulation tools with experimental

Ferromagnetic Resonance Mode Interactions in Periodically Perturbed Films

May 1, 2002
Author(s)
Robert McMichael, D J. Twisselmann, John E. Bonevich, P J. Chen, William F. Egelhoff Jr., Stephen E. Russek
rromagnetic resonance linewidth measurements are reported for thin films of Ni 80Fe 20 deposited on substrates with 320 nm period grooves or parallel aperiodic scratches. These films are model systems for studying the effects of inhomogeneity on

Final Report: Effective Non-Toxic Metallic Fire Suppressants

May 1, 2002
Author(s)
Gregory T. Linteris, M D. Rumminger, Valeri I. Babushok, Harsha K. Chelliah, A K. Lazzarini, P N. Wanigarathne
The purpose of the project was to: a.) identify which metal species would be effective flame inhibitors, and then b.) attempt to find non-toxic forms of the metal which could be used. Very early in the project, however, we determined that metal species-in

Fluorescence in Situ Hybridization (FISH) Methods for Medical Genetics; Proposed Guideline

May 1, 2002
Author(s)
Peter E. Barker, R K. Enns, G Dewalk, D J. Rasmussen, E Shulse, M S. Watson, P R. Wyatt
FISH technology can be used to detect microdeletions that are not visible by standard cytogenetic banding patterns. FISH technology allows for the rapid determination of whether specific genes, loci, or regions are present or if deletions or amplifications
