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

Line Assignments and Global Analysis of the Tunneling-Rotational Microwave Absorption Spectrum of Dimethyl Methylphosphonate

March 1, 2003
Author(s)
N Ohashi, J Pyka, G Y. Golubiatnikow, Jon T. Hougen, R D. Suenram, Francis J. Lovas, A Lesarri, Y Kawashima
Line assignments were carried out for about 600 Fourier transform microwave transitions for dimethyl methylphosphonate involving levels of all six symmetry species in the G 18 molecular symmetry group appropriate for three large-amplitude motions and

Literature Review on Enclosure of Elevator Lobbies

March 1, 2003
Author(s)
D W. Stroup
A literature survey was conducted to explore the need and appropriate systems for protecting elevator lobbies from smoke migration. The focus is on smoke spread through elevator shafts and lobbies, building occupant and fire fighter use of elevators during

Magnetic Thin Film Interlaboratory Comparison

March 1, 2003
Author(s)
Fabio C. da Silva, David P. Pappas, C. M. Wang
A potential low magnetic moment standard reference material (SRM) was studied in an interlaboratory comparison. The mean and the standard deviation of the saturation moment m s, the remanent moment m r, and the intrinsic coercivity H c of nine samples were

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
