Characteristics of Fire Scenarios in Which Sublethal Effects of Smoke Are Important

April 1, 2004
Author(s)
Richard D. Peacock, Jason D. Averill, Paul A. Reneke, Walter W. Jones
A number of simulations were performed using the CFAST zone fire model to predict the relative times at which smoke inhalation and heat exposure would result in incapacitation. Fires in three building types were modeled: a ranch house, a hotel, and an

Comparative Specular X-Ray Reflectivity, Positron Annihilation Lifetime Spectroscopy, and Incoherent Neutron Scattering Measurements of the Dynamics in Thin Polycarbonate Films

April 1, 2004
Author(s)
Christopher L. Soles, Jack F. Douglas, Wen-Li Wu, H G. Peng, D W. Gidley
The manner in which the dynamics of a polymer are affected by thin film confinement is one of technological significance, impacting thin film applications such as lubricants, adhesives, and chemically amplified photoresists. In this manuscript we use

Comparing the Transient Response of a Resistive-Type Sensor With a Thin Film Thermocouple During the Post-Exposure Bake Process

April 1, 2004
Author(s)
Kenneth G. Kreider, D P. DeWitt, J B. Fowler, J E. Proctor, William A. Kimes, Dean C. Ripple, Benjamin K. Tsai
Recent studies on dynamic temperature profiling and lithographic performance modeling of the post-exposure bake (PEB) process have demonstrated that the rate of heating and cooling may have an important influence on resist lithographic response. Generally

Dental Composites Based on Hybrid and Surface-Modified Amorphous Calcium Phosphates

April 1, 2004
Author(s)
Drago Skrtic, Joseph M. Antonucci, E D. Eanes, Naomi Eidelman
The objectives of this study were to examine the feasibility of preparing hybrid and surface-modified amorphous calcium phosphates (ACP) as fillers for mineral-releasing dental composites and determine whether the mechanical strength of the composites

Dipole Moment of a Pb-O Vacancy Pair in PbTiO 3

April 1, 2004
Author(s)
Eric J. Cockayne, Benjamin P. Burton
The polarization of a nearest-neighbor (nn) Pb-O vacancy pair in PbTiO3 is calculated, using the modern theory of polarization, implemented in the density functional theory ultrasoft pseudopotential formalism. The dipole moment per divacancy is about 2.228

Dynamic Mechanical Analysis of Pure Mg and Mg AZ31 Alloy

April 1, 2004
Author(s)
A -. Munitz, D -. Dayan, David J. Pitchure, Richard E. Ricker
Dynamic mechanical analyses were performed on pure Mg and Mg AZ31 alloy to study the impact of thermo-mechanical state and grain structure on the complex modulus (E*=E'+iE). The storage modulus (E') of pure Mg was found to be (40.0+2.5) GPa and indpendent

Enterprise Simulation: A Hybrid System Approach

April 1, 2004
Author(s)
Luis C. Rabelo, M Helal, Hyeung-Sik Min, Albert T. Jones
Manufacturing enterprise decisions can be classified into four groups: business decisions, design decisions, engineering decisions, and production decisions. Numerous physical and software simulation techniques have been used to evaluate specific decisions

Fire Safety of Passenger Trains. Phase 3. Evaluation of Fire Hazard Analysis Using Full-Scale Passenger Rail Car Tests (NISTIR 6563)

April 1, 2004
Author(s)
Richard D. Peacock, Jason D. Averill, Daniel M. Madrzykowski, D W. Stroup, Paul A. Reneke, Richard W. Bukowski
Fire safety is an area of particular interest for both conventional intercity and commuter passenger trains, and new high-speed trains. A systems approach to fire safety addresses passenger rail car design and materials, detection and suppression

Forensic Software Testing Support Tools: Test Summary Report

April 1, 2004
Author(s)
Elizabeth N. Fong, Serban I. Gavrila
The Computer Forensic Tool Testing (CFTT) project at the National Institute of Standards and Technology (NIST), an agency of the United States Department of Commerce, provides a measure of confidence in the software tools used in computer forensic

Generation and Transport of Smoke Components

April 1, 2004
Author(s)
Kathryn M. Butler, George W. Mulholland
Smoke is a mixture of gases and suspended particulate matter, or aerosols. The nature of the aerosol component of smoke can play a significant role in the lethal and sublethal effects on people. This paper presents the current state of knowledge about

Improved Thermal Stability of Organically Modified Layered Silicates

April 1, 2004
Author(s)
Rick D. Davis, Jeffrey W. Gilman, T E. Sutto, J H. Callahan, Paul C. Trulove, Hugh C. De Long
Bromide containing impurities were found to decrease the thermal stability of quaternary alkyl ammonium modified layered silicates. Improved purification procedures completely removed these bromide anions and led to a 20 C to > 100 C increase in organic

Improving Software Quality Through Better Design and Testing

April 1, 2004
Author(s)
John Barkley, Mark Skall
Our results extending Kuhn's fault class hierarchy provide a justification for the focus of fault-based testing strategies on detecting particular faults and ignoring others. We develop a novel analytical technique that allows us to elegantly prove that

Improving the Usability and Accessibility of Voting Systems and Products

April 1, 2004
Author(s)
Sharon J. Laskowski, James H. Yen, M Autry, John V. Cugini, W Killam
In the Help America Vote Act (HAVA) of 2002, Public Law 107-252, the Election Assistance Commission, in consultation with the National Institute of Standards and Technology, is mandated to submit a report on human factors, usability, and accessibility to
