Defining Flashover for Fire Hazard Calculations: Part II

November 1, 2003
Author(s)
V Babrauskas, Richard Peacock
Comparison of available correlations and predictive models used to predict the minimum energy necessary to cause flashover show consistent estimates for a range of empirical data. Still, available experimental data show a wide range of heat release rates

Discussion of Definition of Wind Profiles in ASCE 7 by Yin Zhou and Ahsan Kareem

November 1, 2003
Author(s)
Emil Simiu, Fahim Sadek, Michael A. Riley
The discussion presents a critique of a paper published in the Journal of Structural Engineering, Aug. 2002, pp. 1082-1086. The main points of the discussion are: (1) the ASCE Standard definition of wind profiles is inconsistent with the ASCE definition of

Elastic Constants of Layers in Isotropic Laminates

November 1, 2003
Author(s)
F Hayliger, H M. Ledbetter, Sudook A. Kim, Ivar E. Reimanis
We determined the individual laminae elastic constants in multilayer laminates composed of dissimilar isotropic layers using acoustic resonance spectroscopy and the linear theory of elasticity. Resonant ultrasound allows one to measure the free-vibration

Enemies at the Gates: Securing the BACnet building

November 1, 2003
Author(s)
David G. Holmberg
This article seeks to increase awareness of the threats associated with connecting the building control system (specifically a BACnet system) to a wider network. In addition, it presents countermeasures available for addressing security threats

Exploring and Extending the Limits of CD-SEMs' Resolution

November 1, 2003
Author(s)
Andras Vladar, Michael T. Postek, John S. Villarrubia
This study of SEM resolution is occasioned by concerns that it is no longer adequate for lithography process control in integrated circuit manufacturing. For example, according to the most recent International Technology Roadmap for Semiconductors, the in

Extinction Near-Field Optical Microscopy

November 1, 2003
Author(s)
H F. Hamann, M Larbadi, S Barzen, T Brown, Alan Gallagher, David Nesbitt
Two AFM-assisted, apertureless, optical-imaging methods are presented. These overcome the severe resolution consrtaints of aperture-based Near-field Scanning Optical Microscopy by probing the highly localized mutual near-field interaction between AFM-tip

Fundamental Electron Interactions with Plasma Processing Gases

November 1, 2003
Author(s)
Loucas G. Christophorou, James K. Olthoff
This volume deals with the basic knowledge and undestanding of fundamtal interactions of low energy electrons with molecules. It provides an up-to-date and comprehensive account of the fundamental interactions of low energy energy electrons with molecules

High Frequency Loss Mechanism in Polymers Filled With Dielectric Modifiers

November 1, 2003
Author(s)
Jan Obrzut, A Anopchenko, K Kano, Haonan Wang
We analyzed the high frequency dielectric relaxation mechanism in high-k composite materials using film substrates made of low loss organic resin filled with ferrolectric ceramics and with single wall carbon nanotubes (SWNT). The highest frequencey

High Throughput Methods for Polymer Nanocomposites Research: Extrusion, Nmr Characterization and Flammability Property Screening.

November 1, 2003
Author(s)
Jeffrey W. Gilman, S Bourbigot, John R. Shields, Marc R. Nyden, Takashi Kashiwagi, Rick D. Davis, David L. VanderHart, W Demory, C A. Wilkie, A B. Morgan, J R. Harris, R Lyon
Several, recent, revolutionary advances in combinatorial (or high throughput, HT) polymer science have appeared in the literature, which significantly accelerate the rate of data generation. Although these new HT approaches may in part have been inspired

Infrared Spectra of trans-HOCO, HCOOH + , and HCO 2 - Trapped in Solid Neon

November 1, 2003
Author(s)
D Forney, Marilyn E. Jacox, Warren E. Thompson
When a Ne: HCOOH sample is codeposited at ca. 5 K with neon atoms that have been passed through a microwave discharge, new absorptions appear in the infrared spectrum of the resulting solid which can be assigned to trans-HOCO, trans-HCOOH +, and HCO 2 -

MatML: A Data Interchange Markup Language

November 1, 2003
Author(s)
J G. Kaufman, E F. Begley
This paper updates and expands upon previously published information on MatML, a new extensible markup language designed specifically for the exchange of materials information. In particular, it will describe the strengths of MatML from the perspective of

Microscopy and Spectroscopy of Lithium Nickel Oxide Based Particles Used in High-Power Lithium-Ion Cells

November 1, 2003
Author(s)
D Abraham, R D. Twesten, Mahalingam Balasubramanian, J Kropf, Daniel A. Fischer, James McBreen, I Petrov, K Amine
Structural and electronic investigations were conducted on lithium nickel oxide based particles used in positive electrodes of 18650-type high power lithium-ion cells. K-edge X-ray absorption spectroscopy (XAS) revealed trivalent Ni and Co ions in the bulk
