Real-Time I/O Performance Metrics and Tests for Industrial Ethernet

April 28, 2004
Author(s)
James D. Gilsinn
Real-time input/output (I/O) communication over Ethernet is still fairly new in the industrial environment. There are many questions about the reliability and performance that have to be answered before industrial Ethernet can be utilized in most

Suppression of Cup-Burner Flames Using Carbon Dioxide in Microgravity

April 1, 2004
Author(s)
V Katta, F Takahashi, Gregory T. Linteris
Carbon dioxide extinguishes flames through dilution process. The extinction characteristics of CO2 were previously studied using a cup-burner flame under normal-gravity conditions. As the diffusion flames behave differently in microgravity compared to

Thickness Evaluation for 2nm SiO2 Films, a Comparison of Ellipsometric, Capacitance-Voltage and HRTEM Measurements

September 30, 2003
Author(s)
James R. Ehrstein, Curt A. Richter, Deane Chandler-Horowitz, Eric M. Vogel, Donnie R. Ricks, Chadwin Young, Steve Spencer, Shweta Shah, Dennis Maher, Brendan C. Foran, Alain C. Diebold, Pui-Yee Hung
We have completed a comparison of SiO2 film thicknesses obtained with the three dominant measurement techniques used in the IC industry . This work is directed at evaluating metrology capability that might support NIST- traceable Reference Materials for

Magnetization Dynamics Modeled in Magnetic Thin Films

March 1, 2003
Author(s)
Robert D. McMichael
One of the challenges facing designers of high data rate computer hard drives and magnetic memory chips is that for most magnetic metals, it typically takes a fewnanoseconds for the magnetization to come to rest after it has been switched or bumped by a

Extinction Characteristics of Cup-Burner Flame in Microgravity

January 1, 2003
Author(s)
V Katta, F Takahashi, Gregory T. Linteris
Carbon dioxide extinguishes flames through dilution process. The extinction characteristics of CO2 were previously studied using a cup-burner flame under normal-gravity conditions. As the diffusion flames behave differently in microgravity compared to

BACnet Unraveled

August 1, 2001
Author(s)
Steven T. Bushby
Publication of ASHRAE and ANSI's BACnet communication protocol in 1995 ushered in a new era for building automation and control systems, making it possible to integrate building control products designed by different manufacturers. This change has proved

Single-Integral-Equation Method for Scattering by Dielectric Cylinders

July 1, 2001
Author(s)
Egon Marx
Electromagnetic scattering of an incident plane monochromatic wave by dielectric or finitely conducting infinite cylinders of arbitrary shape, possibly in the presence of a substrate, can be reduced to the solution of scalar Helmholtz equations in two

SO x Radical Monoanions--Reactions in Solution and in the Gas Phase

February 1, 1999
Author(s)
Robert E. Huie, L W. Sieck
Sulfur dioxide, SO 2, is a major air pollutant and a natural trace atmospheric constituent. The major anthropogenic source of SO 2 is the combustion of fossil fuels, although much also arises from scrubbing natural gas and from smelting sulfide ores (1)

Mean Recurrence Intervals of Ultimate Wind Loads

July 1, 1998
Author(s)
Emil Simiu, A N. Heckert, T Whalen
The attention of wind engineers and extreme value climatologists has been focused in the last few decades on estimates of basic windspeeds, that is, wind speeds with 50 year or 100 year mean recurrence intervals (MRIs). Recently, however, efforts have been

Crystal Structure and Properties of Ba 5 Fe 4 ^Ti 10 O 31

February 23, 1998
Author(s)
T Siegrist, Terrell A. Vanderah, A P. Ramirez, Richard G. Geyer, Robert S. Roth
Using single-crystal and powder X-ray diffraction methods, the crystal structure of the new compound Ba 5Fe 4Ti 10O 31 was determined and its magnetic and dielectric properties were measured. Ba 5Fe 4Ti 10O 31 crystallizes in space group P6 3/mcm (no. 193)

On Migrating ISO 10303 PMI Models to a Common Core

January 4, 2023
Author(s)
Allison Barnard Feeney, Thomas Thurman
Industrial users of ISO 10303 STandard for the Exchange of Product Model Data (STEP) protocols needed the ability to exchange design product data that is in conformance with recently updated ISO geometric product specification (GPS) standards, the American

Anisotropic chemical bonding of lanthanide-OH molecules

July 1, 2025
Author(s)
Jacek Klos, Eite Tiesinga, Lan Cheng, Svetlana Kotochigova
We present a theoretical study of the low lying adiabatic relativistic electronic states of lanthanide monohydroxide (Ln-OH) molecules near their linear equilibrium geometries. In particular, we focus on heavy, magnetic DyOH and ErOH relevant to

Simulated inter-filament fusion in embedded 3D printing

November 15, 2024
Author(s)
Leanne Friedrich, Ross Gunther
In embedded 3D printing (EMB3D), a nozzle extrudes continuous filaments inside of a viscoelastic support bath. Compared to other extrusion processes, EMB3D enables softer structures and print paths that conform better to the shape of the part. However

High-resolution Melt Pool Thermal Imaging for Metals Additive Manufacturing Using the Two-color Method with a Single Color Camera

July 5, 2023
Author(s)
Alexander Myers, Guadalupe Quirarte, Francis Ogoke, Brandon Lane, Syed Uddin, Amir Barati Farimani, Jack Beuth, Jonathan Malen
We introduce an experimental method to image melt pool temperature with a single commercial color camera and compare the results with multi-physics computational fluid dynamic (CFD) models. This approach leverages the principle of two-color (i.e
