Maps of Non-hurricane Non-tornadic Wind Speeds With Specified Mean Recurrence Intervals for the Contiguous United States Using a Two-Dimensional Poisson Process Extreme Value Model and Local Regression

November 12, 2015
Author(s)
Adam L. Pintar, Emil Simiu, Franklin T. Lombardo, Marc L. Levitan
This report describes a procedure for creating maps of non-hurricane, non-tornadic wind speeds for a set of recurrence intervals of interest between \num{10} and \num{100000} years over the contiguous United States. The procedure is carried out in two

Optimizing Hybrid Metrology: Rigorous Implementation of Bayesian and Combined Regression.

Hybrid metrology, e.g. the combination of several measurement techniques to determine critical dimensions, is an important approach to meet the needs of semiconductor industry. A proper use of hybrid metrology may not only yield more reliable estimates for

The Practice of Pulse Processing

Joseph W. Fowler, Bradley K. Alpert, William B. Doriese, Young Il Joe, Galen C. O'Neil, Joel N. Ullom, Daniel S. Swetz
The analysis of data from x-ray microcalorimeters requires great care; their excellent intrinsic energy resolution cannot usually be achieved in practice without a statistically near-optimal pulse analysis and corrections for important systematic errors

Thermally stable thin-film filters for high-power extreme-ultraviolet applications

Charles S. Tarrio, Robert F. Berg, Thomas B. Lucatorto, Bruce Lairson, Heidi Lopez, Travis Ayers
We investigated several types of thin-film filters for high intensity work in the extreme-ultraviolet (EUV) spectral range. In our application, with a peak EUV intensity of 2.7 W cm-2, Ni-mesh-backed Zr filters have a typical lifetime of 20 hours, at which

Identifying Performance Assurance Challenges for Smart Manufacturing

November 11, 2015

Moneer M. Helu, Katherine C. Morris, Kiwook Jung, Kevin W. Lyons, Swee K. Leong
Smart manufacturing has the potential to address many of the innovation drivers faced by industry. However, the manufacturing community often needs assistance to develop and use the variety of available technologies to improve their systems. To assure the

Optical Control of Spin-Valley-Orbital States of Group-V Donors in Silicon

November 11, 2015
Author(s)
Michael Gullans, Jacob M. Taylor
We show how to to achieve spin-selective excitation of the valley-orbit states of group-V donors (P, As, Sb, Bi) in silicon using optical fields. We consider two approaches based on exploiting resonant, far-infrared (IR) transitions of the neutral donor or

Determination of high-molecular weight polycyclic aromatic hydrocarbons in high performance liquid chromatography fractions of coal tar standard reference material 1597a via solid-phase nanoextraction and laser-excited time-resolved Shpolskii spectr

November 10, 2015
Author(s)
Walter B. Wilson, Bassam Alfarhani, Cristina Bisson, Stephen A. Wise, Andres Campiglia
This article presents an alternative approach for the analysis of high molecular weight – polycyclic aromatic hydrocarbons (HMW-PAHs) with molecular mass 302 Da in complex environmental samples. This is not a trivial task due to the large number of
