Variances of Plane Parameters Fitted to Range Data

May 5, 2010
Author(s)
Marek Franaszek
Formulas for variances of plane parameters fitted with Nonlinear Least Squares to points cloud acquired by 3D imaging systems (e.g., LADAR) are derived. Two different error functions used in minimization are discussed: the orthogonal and the directional

Deactivation of Sub-Melt Laser Annealed Arsenic Ultra Shallow Junctions in Silicon During Subsequent Thermal Treatment

May 4, 2010
Author(s)
Joseph C. Woicik, D. Giubertoni, G. Pepponi, S. Gennaro, M. Bersani, M. A. Sahiner, S. P. Kelty, M. Kah, K. J. Kirkby, R. Doherty, M. A. Foad, F. Meirer, C. Streli, P. Pianetta
The use of non-equilibrium annealing approaches can produce a very high level of arsenic electrical activation in Si but subsequent thermal treatments between 500 and 800 C easily deactivate the dopant to a level one order of magnitude below the solid

SANS from P85/Water-d Under Pressure

May 4, 2010
Author(s)
Bryna Clover, Boualem Hammouda
Pluronics are triblock copolymers of PEO-PPO-PEO. Pluronic P85 forms a rich phase behavior when dissolved in water. Unimers are observed at low temperature while micelles form at higher temperatures. Spherical, cylindrical and lamellar micelles are

Absence of the Hyperfine Magnetic Field at the Ru Site in Ferromagnetic Rare-Earth Intermetallics

May 3, 2010
Author(s)
D. Coffey, M. DeMarco, P.C. Ho, M. B. Maple, T. Sayles, Jeffrey W. Lynn, Qingzhen Huang, S. Toorongian, M. Haka
The Mossbauer Effect(ME) is frequently used to investigate magnetically ordered systems. One usually assumes that the magnetic order induces a hyperfine magnetic field, B hyper fine, at the ME active site. This is the case in the ruthenates, where the

Better IAQ using ASHRAE Guide

May 3, 2010
Author(s)
Andrew K. Persily, Martha Hewett
Over the years, there have been many important contributions directed towards improving IAQ in buildings, including Standard 62.1 and other publications (EPA and NIOSH 1991; SMACNA 2007). In addition, ASHRAE, the International Society for Indoor Air

Estimating Volumes of Near-spherical Molded Artifacts

May 3, 2010
Author(s)
David E. Gilsinn, Bruce R. Borchardt, Amelia Tebbe
The Food and Drug Administration (FDA) is conducting research on developing reference lung cancer cancer lesions, called phantoms, to test computed tomography (CT) scanners and their software. FDA loaned two semi-spherical phantoms to the National

Gate Dielectrics Year-In-Review

May 3, 2010
Author(s)
Jason P. Campbell
The gate dielectrics year-in-review includes a comprehensive examination of the past year s reports which detail gate stack reliability issues and the corresponding physical mechanisms which limit the performance and lifetimes of advanced devices. The
