High resolution 17 keV to 75 keV backlighers for high energy density experiments

November 6, 2008
Author(s)
Lawrence T. Hudson, H.S. Parks, B.R. Maddox, E. Giraldez, P. Hatchett, N. Izumi, M.H. Key, S. LePape, A. MacKinnon, A MacPhee, P.K. Patel, T.W. Phillips, B.A. Remington, John F. Seely, A. Tommasini, R. Town, J. Workman
We have developed 17 keV to 75 keV 1-dimensional and 2-dimensional high-resolution (<10 m) radiography using high-intensity short pulse lasers. High energy K- sources are created by fluorescence from hot electrons interacting in the target material after

Avoided crossings between bound states of ultracold Cesium dimers

November 5, 2008
Author(s)
Jeremy M. Hutson, Eite Tiesinga, Paul S. Julienne
We present a new computational method for calculating bound states of ultracold alkali metal dimers in the presence of magnetic fields. The new method is based on propagation of coupled differential equations and does not use a basis set for the

Correlation of Local Structure and Electrical Activation in Arsenic Ultra Shallow Junctions in Silicon

November 5, 2008
Author(s)
D. Giubertoni, Giancarlo Pepponi, Salvatore Gennaro, Massimo Bersani, M A. Sahiner, Stephen P. Kelty, Roisin Doherty, Majeed A. Foad, Max Kah, Karen J. Kirkby, Joseph Woicik
The understanding of the behavior of arsenic in highly doped near surface silicon layers is of crucial importance for the formation of N-type Ultra Shallow Junctions in current and future VLSI technology. This is of peculiar relevance when studying novel

Ontology-based Technologies - Technology Transfer from Bioinformatics?

November 5, 2008
Author(s)
Fabian M. Neuhaus
In the call for paper for OIC 2008 the description of the conference contains the following optimistic outlook: New approaches are required to enable greater flexibility, precision, timeliness and automation of analysis in response to rapidly evolving

Overview of the TREC 2006 Question Answering Track

November 5, 2008
Author(s)
Hoa T. Dang, Jimmy Lin, Diane Kelly
The TREC 2006 question answering track contained two tasks: a main task and a complex, interactive question answering (ciQA) task. As in 2005, the main task consisted of series of factoid, list, and ``Other'' questions organized around a set of targets

User's Guide for the Quality of Design Testing Tool and the Content Checker

November 5, 2008
Author(s)
Katherine C. Morris, Simon P. Frechette, Puja Goyal, Joshua Lubell, Boonserm Kulvatunyou, Salifou Sidi Malick, Nicolas Brayard, Severin Tixier
This document describes the operation and usage of the Quality of Design and the Content Checker Testing Tools. These tools were developed at the National Institute of Standards and Technology (NIST) to support people in developing standards for the

Calibration of a Computer Assisted Orthopedic Hip Surgery Phantom

November 4, 2008
Author(s)
Daniel S. Sawyer, Nicholas G. Dagalakis, Craig M. Shakarji, Yong Sik Kim
Orthopedic surgeons have identified a need for calibration artifacts (phantoms) to establish the traceability (to the SI unit of length) of measurements performed with Computer Assisted Orthopedic Surgery (CAOS) systems. These phantoms must be lightweight

HF RFID Electromagnetic Emissions and Performance

November 4, 2008
Author(s)
David R. Novotny, Jeffrey R. Guerrieri, Michael H. Francis, Catherine A. Remley
We examined the emissions, and susceptibility of commercial High-Frequency Radio Frequency Identification (HF proximity RFID) systems to interrupt and eavesdropping. RFID systems are being used in an increasing number of financial, identification, and

Extraction of Sheet Resistance and Line Width from All-Copper ECD Test Structures Fabricated from Silicon Preforms

November 3, 2008
Author(s)
Byron J. Shulver, Andrew S. Bunting, Alan Gundlach, Les I. Haworth, Alan W. Ross, Stewart Smith, Anthony J. Snell, J. T. Stevenson, Anthony Walton, Richard A. Allen, Michael W. Cresswell
Test structures have been fabricated to allow Electrical Critical Dimensions (ECD) to be extracted from copper features with dimensions comparable to those replicated in IC interconnect systems. The implementation of these structures is such that no

Impacts of Information Technologies on Performance: A Cross Study Comparison

November 3, 2008
Author(s)
Yongcheol Kang, William O'Brien, Stephen R. Thomas, Robert E. Chapman
This paper evaluates the use of Information Technology (IT) and its impact on project and company performance in the construction industry. Using project level data from 139 projects and company level data from 74 companies, the current state of IT use in

Standards Development for Gas Phase Air Cleaning Equipment in Buildings

November 3, 2008
Author(s)
Andrew K. Persily, Cynthia H. Reed, Stephanie S. Watson, Nicos Martys, Edward J. Garboczi, Heather Davis
Concerns about building security have resulted in increasing interest in gas phase air cleaning (GPAC) and the need for standard methods to determine the effectiveness of these systems. Similarly, the ability to predict their installed performance, based

Probability Density Function of Power Received in a Reverberation Chamber

November 2, 2008
Author(s)
David A. Hill
The probability density function (PDF) for the power received by an arbitrary antenna in a reverberation chamber has been shown to be exponential. The purpose of this correspondence is to provide a direct maximum-entropy derivation of the PDF that deals

A Comparison of Viscosity-Concentration Relationships for Emulsions

November 1, 2008
Author(s)
Jeffrey W. Bullard, A T. Pauli, Edward J. Garboczi, Nicos Martys
Differential Effective Medium Theory (D-EMT) is applied to derive expressions for the viscosity of a colloidal suspension or an emulsion as a function of the volume fraction of the dispersed phase. The application of D-EMT to this problem depends on how

A robust algorithm for eye-diagram analysis

November 1, 2008
Author(s)
Jeffrey A. Jargon, Paul D. Hale, Chih-Ming Wang
We present a new method for analyzing eye diagrams that always provides a unique solution by making use of a robust, least-median-of-squares (LMS) location estimator. In contrast to commonly used histogram techniques, the LMS procedure is insensitive to
