Exploring and Extending the Limits of CD-SEMs' Resolution

March 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

Face Recognition Vendor Test 2002 Performance Metrics

March 1, 2003
Author(s)
Patrick Grother, Ross J. Micheals, P. Jonathon Phillips
We present the methodology and recognition performance characteristics used in the Face Recognition Vendor Test 2002. We refine the notion of a biometric imposter, and show that the traditional measures of identification and verification performance are

Face Recognition Vendor Test 2002: Evaluation Report

March 1, 2003
Author(s)
P J. Phillips, Patrick J. Grother, Ross J. Micheals, D M. Blackburn, Elham Tabassi, M Bone
The Face Recognition Vendor Test (FRVT) 2002 is an independently administered technology evaluation of mature face recognition systems. FRVT 2002 provides performance measures for assessing the capability of face recognition systems to meet requirement for

Flame Heights and Heat Release Rates of 1991 Kuwait Oil Field Fires (NIST SP 995)

March 1, 2003
Author(s)
D. D. Evans, Daniel M. Madrzykowski, G A. Haynes
A series of measurements were made in the Al Mawqa/Al Ahmadi oil field region of Kuwait to explore the feasibility of assessing the heat release rate of individual well fires through flame height and thermal radiation measurements. The heat release rate

Flexible and Rapidly Configurable Femtosecond Pulse Generation in the Mid-IR

March 1, 2003
Author(s)
S M. Foreman, D J. Jones, Jun Ye
We demonstrate a new experimental approach for flexible femtosecond pulse generation in the mid-IR using difference-frequency-generation from two tightly synchronized Ti: sapphire lasers. The resultant mid-IR pulse train can be easily tuned, with an

In Situ Burning of Oil Spills: Mesoscale Experiments and Analysis (NIST SP 995)

March 1, 2003
Author(s)
William D. Walton, D. D. Evans, Kevin B. McGrattan, Howard R. Baum, W H. Twilley, Daniel M. Madrzykowski, Anthony D. Putorti Jr., Ronald G. Rehm, H Koseki, E J. Tennyson
A series of six mesoscale and one large laboratory fire experiments were performed to measure the burning characteristics of Louisiana crude oil on water in a pan. These included one - 6 m square and five - 15 m square mesoscale burns and one - 1.2 m

In Situ TEM Observations of Fracture in Nanolaminated Metallic Thin Films

March 1, 2003
Author(s)
Timothy J. Foecke, D E. Kramer
Fracture of single crystal nanolaminted thin films has been investigated through in situ straining of cross-sectional samples of Cu/Ni nanolaminates grown on Cu (001) single crystal substrates. The earliest stages of deformation exhibits a confined layer

In-Situ Burning in the Marshland Environment - Recovery and Regrowth of Spartina Alterniflora, Spartina Patens, and Sagittaria Lancifolia Plants

March 1, 2003
Author(s)
I A. Mendelson, Q N. Lin, Nelson P. Bryner, William D. Walton, W H. Twilley, J V. Mullin
In a series of in-situ burns involving 330 plant mesocosms, including Spartina Alterniflora, Spartina Patens, Distichlis spicata, and Sagittaria Lancifolia sods were exposed to burning diesel fuel or crude oil. Oil spilled in sensitive wetlands pose unique

In-Situ Burning in the Marshland Environment - Soil Temperatures Resulting From Crude Oil and Diesel Fuel Burns (NIST SP 995)

March 1, 2003
Author(s)
Nelson P. Bryner, William D. Walton, W H. Twilley, G Roadarmel, I. A. Mendelssohn, J. V. Mullin
A series of burns was conducted to evaluate the impact of intentional burning of an oil spill in a marshland environment. Oil spilled in sensitive wetland environments pose unique problems associated with cleanup because mechanical recovery in wetlands may

In-Situ Burning in the Marshland Environment-Soil Temperatures. Volume 2 (NIST SP 995)

March 1, 2003
Author(s)
Nelson P. Bryner, William D. Walton, Laurean A. DeLauter, W H. Twilley, I. A. Mendelssohn, Q. Lin
A series of burns was conducted to evaluate the impact of intentional burning of an oil spill in a marshland environment. Oil spilled in sensitive wetland environments pose unique problems associated with cleanup because mechanical recovery in wetlands may

In-Situ Burning of Oil Spills: Mesoscale Experiments (NIST SP 995)

March 1, 2003
Author(s)
D. D. Evans, William D. Walton, Howard R. Baum, Kathy A. Notarianni, James R. Lawson, Hai C. Tang, K. R. Keydel, Ronald G. Rehm, Daniel M. Madrzykowski, Richard H. Zile, H Koseki, E J. Tennyson
In 1991 a series of 14 mesoscale fire experiments were performed to measure the burning characteristics of crude oil on salt water. These oil burns in a pan ranged in size from 6 m square to 15 m square. Results of the measurements for burning rate and

Joint Distribution of Link Distances

March 1, 2003
Author(s)
Leonard E. Miller
The calculation of two-hop connectivity between two terminals for randomly deployed wireless networks requires the joint probability distribution of the distances between these terminals and the terminal that is acting as a relay. In general the distances

Large Fires: Kuwait (NIST SP 995)

March 1, 2003
Author(s)
Daniel M. Madrzykowski, D. D. Evans, G A. Haynes
A series of measurements were made in the Al Mawqa/Al Ahmadi oil field region of Kuwait to explore the feasibility of assessing the heat release rate of individual well fires through flame height and thermal radiation measurements. The 12 fires measured
