Effect of Phase Change and Solute Diffusion on Spreading on a Dissolving Substrate

October 1, 2010
Author(s)
Walter Villanueva, William J. Boettinger, James A. Warren, Gustav Amberg
Dissolutive wetting is investigated numerically using a diffuse-interface model that incorporates fluid flow, solute diffusion, and phase change. A range of materials parameters are investigated that: 1) permits recovery of the hydrodynamic limit by

Fire Effluent Component Yields from Room-scale Fire Tests

October 1, 2010
Author(s)
Richard G. Gann, Jason D. Averill, Erik L. Johnsson, Marc R. Nyden, Richard D. Peacock
Estimation of the time available for escape (ASET) in the event of a fire is a principal component in fire hazard or risk assessment. Valid data on the yields of toxic smoke components from bench-scale apparatus is essential to accurate ASET calculations

Future SC4 Architecture PWI - Report and Technical Discussion

October 1, 2010
Author(s)
Allison Barnard Feeney
This document is the report of the Future SC4 architecture PWI. It provides information about the draft “Industrial Data Integrated Ontologies and Models (IDIOM) architecture specification” created by the PWI. The work of the Preliminary Work Item (PWI)

Intercomparison of Methods for Detecting and Characterizing Voids in Bonded Wafer Pairs

October 1, 2010
Author(s)
Richard A. Allen, Andrew C. Rudack, David T. Read, Winthrop A. Baylies
The Wafer Bond Task Force of the SEMI MEMS Standards Committee has begun a round robin experiment to evaluate methods for identifying and characterizing voids in bonded wafer pairs for three-dimensional integrated circuit (3D IC) applications. Due to the

Nano- and Atom-scale Length Metrology

October 1, 2010
Author(s)
Theodore V. Vorburger, Ronald G. Dixson, Ndubuisi G. Orji, Joseph Fu, Richard A. Allen, Michael W. Cresswell, Vincent A. Hackley
Measurements of length at the nano-scale have increasing importance in manufacturing, especially in the electronics and biomedical industries. The properties of linewidth and step height are critical to the function and specification of semiconductor

Thermal Noise and Noise Measurements a 2010 Update

October 1, 2010
Author(s)
Anthony R. Kerr, James P. Randa
1. Introduction 2. Noise Temperature as a Measure of Noise Power 3. Available Noise Power from a Resistor 4. The Zero-Point Noise Term and the Minimum Noise of an Amplifier 5. Noise-Temperature Standards and Measurement of One-Port Noise Sources 6

BEES Online: Life Cycle Analysis for Building Products

September 30, 2010
Author(s)
Barbara C. Lippiatt, Anne L. Greig, Priya D. Lavappa
The BEES (Building for Environmental and Economic Sustainability) Online web application implements a rational, systematic technique for selecting environmentally-preferred, cost-effective building products. The technique is based on consensus standards

Concrete Model Building Subtypes

September 30, 2010
Author(s)
William T. Holmes
This study was conducted by the National Institute of Building Sciences Building Seismic Safety Council (BSSC). The goal was to develop standardized categories for older concrete buildings that incorporate more detail than those included in the standard

Constraint Generator User's Guide

September 30, 2010
Author(s)
Salifou Sidi Malick, Matthew Molek, Katherine C. Morris
This document describes the Constraint Generator. The Constraint Generator is a tool developed at NIST to automate the generation of schematron scripts for an advance validation of XML documents. The tool allows the user to open an XSD schema, view a tree

Economics of Egress Alternatives and Life-Safety Costs

September 30, 2010
Author(s)
Robert E. Chapman, David T. Butry, Allison L. Huang, Douglas S. Thomas
Fire protection measures are needed to maintain the safety and integrity of the Nation s building stock and to limit loss of life and property when building fires do occur. Statistics published by the National Fire Protection Association demonstrate that

Ethics and the Cloud

September 30, 2010
Author(s)
Keith Miller, Jeff Voas
Cloud computing is an idea that's rapidly evolving. Still, the amount of money and attention devoted to this topic makes it seems sensible to discuss how ethicists view the kinds of changes in computing that are being called "the cloud." This department is

Guide to Securing WiMAX Wireless Communications

September 30, 2010
Author(s)
Karen A. Scarfone, Cyrus Tibbs, Matt Sexton
The purpose of this document is to provide information to organizations regarding the security capabilities of wireless communications using WiMAX networks and to provide recommendations on using these capabilities. WiMAX technology is a wireless

Impossibility of a pure resistance measurement: The charge-pileup model

September 30, 2010
Author(s)
Neil M. Zimmerman, Denis Mamaluy
Recently, we have experimentally demonstrated the existence of a capacitance between conductors, in the absence of an insulator. We show that a combination of current continuity and Poisson's equation leads to a charge pileup, and thus a capacitance

MEMS Young's Modulus and Step Height Measurements with Round Robin Results

September 30, 2010
Author(s)
Janet M. Cassard, Richard A. Allen, Craig D. McGray, Jon C. Geist
This paper presents the results of a microelectromechanical systems (MEMS) Young s modulus and step height round robin experiment, completed in April 2009, which compares Young s modulus and step height measurement results at a number of laboratories. The

Methodology for Calculating Construction Industry Supply Chain Statistics

September 30, 2010
Author(s)
Douglas S. Thomas
Data from the Economic Census provides detailed statistics on the construction industry; however, the data is only gathered every five years. The Bureau of Labor Statistics provides statistics on the construction industry on an annual basis, but these

Security Architecture Design Process for Health Information Exchanges (HIEs)

September 30, 2010
Author(s)
Matthew A. Scholl, Kevin M. Stine, Kenneth Lin, Daniel Steinberg
The purpose of this publication is to provide a systematic approach to designing a technical security architecture for the exchange of health information that leverages common government and commercial practices and that demonstrates how these practices
