Comparison of Gains Determined from the Extrapolation and Pattern Integration Methods

October 30, 2005
Author(s)
Michael H. Francis, Katherine MacReynolds, Jeffrey R. Guerrieri
Scientists at the National Institute of Standards (NIST) have measured the gain of several antennas using two different methods. The first method is the three-antenna extrapolation method developed at NIST in the early 1970s. The second method is the

Planar Near-Field Measurements Results up to 94 GHz Using Probe Position Correction

October 30, 2005
Author(s)
Jeffrey R. Guerrieri, Katherine MacReynolds, Michael H. Francis, Ronald C. Wittmann, Douglas T. Tamura
This paper presents results of planar near-field measurements at 16, 35 and 94 GHz using probe position correction algorithms. The algorithms correct for position errors of the probe near the scan plane. The probe?s actual position is measured using a

Ab Initio Relativistic Calculation of the RbCs Molecule

October 28, 2005
Author(s)
Svetlana A. Kotochigova, Eite Tiesinga
We apply the relativistic configuration interaction valence bond method to calculate various characteristics of the alkali-metal RbCs dimer. These include the electronic potentials and transition dipole moments between the ground and first excited states

Multichannel Quantum-Defect Theory for Slow Atomic Collisions

October 28, 2005
Author(s)
B Gao, Eite Tiesinga, Carl J. Williams, Paul S. Julienne
We present a multichannel quantum-defect theory for slow atomic collisions that takes advantages of the analytic solutions for the long-range potential, and both the energy and the angular-momentum insensitivities of the short-range parameters. The theory

Cross-Property Correlations and Permeability Estimation in Sandstone

October 26, 2005
Author(s)
C H. Arns, M A. Knackstedt, Nicos Martys
Results from a numerical study examining the cross-property correlations linking fluid permeability to conductive properties and to a number of pore size parameters based on 3D digitized images of sedimentary rock are presented. In particular we focus on

Display Daylight Ambient Contrast Measurement Methods and Daylight Readability

October 25, 2005
Author(s)
Edward F. Kelley, Max Lindfors, John Penczek
We propose a composite measurement method to characterize display performance and readability under both daylight and sunlight illumination. The measurements are performed separately in a laboratory, then combined and scaled to daylight and sunlight levels

A Benefit/Cost Model for Metrology in Manufacturing

October 24, 2005
Author(s)
James E. Potzick
Every measurement of a feature's size or placement on a wafer or photomask is made for a reason. Usually a measurement leads to a decision, often involving a process adjustment or business transaction, and there are costs and benefits attached to these

CALCON 2006

October 24, 2005
Author(s)
Marilyn R. Yetzbacher, Michael D. Frenkel
A conference relative to calorimetry held in conjunction with ICCT (Internation Conference on Chemical Thermodynamics) and 16th Symposium on Thermophysical Properties.

Daylight and Sunlight Display Readability Measurement Methods

October 24, 2005
Author(s)
Edward F. Kelley, Max Lindfors, John Penczek
We propose a composite measurement method to characterize display performance and readability under daylight and sunlight illumination. The measurements are performed separately in a laboratory, then combined and scaled to daylight and sunlight levels. Low

Flat-Panel-Display Measurement Techniques and Concerns

October 24, 2005
Author(s)
Edward F. Kelley
Problems encountered in making common measurements on flat panel displays are explored. Existence of stray-light and coping with equipment limitations are stressed. Reflection description and measurement apparatus robustness are reviewed in detail. You

On-demand Single Photons from Individual Epitaxial Quantum Dots

October 24, 2005
Author(s)
Richard P. Mirin, Martin J. Stevens
We will describe our group's efforts to use epitaxial InGaAs/GaAs quantum dots as sources of on-demand single photons and indistinguishable single photons. We have demonstrated second order intensity correlation measurements, g 2τ, with g 2(0) as low as 0

Report on the TREC-5 Confusion Track

October 24, 2005
Author(s)
Paul B. Kantor, Ellen M. Voorhees
This paper is the track report for the TREC-5 confusion track. For TREC-5, retrieval from corrupted data was studied through retrieval of specific target documents from a corpus that was corrupted by applying OCR techniques to page images of varying

The TREC-5 Database Merging Track

October 24, 2005
Author(s)
Ellen M. Voorhees
This paper is the track report for the TREC-5 database merging track. The report motivates the database merging problem, defines the task performed by the participants in detail, and summarizes the main results of the track.

Optical Oscillators with High Stability and Low Timing Jitter

October 22, 2005
Author(s)
Leo W. Hollberg, Christopher W. Oates, Scott A. Diddams
Frequency stabilized cw lasers achieve exceptional frequency stability using high finesse Fabry-Perot cavities. That stability can be transferred to other optical frequencies with mode-locked lasers and provides optical and electronic pulses with ultra-low

Acoustic Modes and Elastic Properties of Polymeric Nanostructures

October 21, 2005
Author(s)
R Hartschuh, A Kisliuk, V N. Novikov, Alexei Sokolov, Paul R. Heyliger, Colm Flannery, Ward L. Johnson, Christopher Soles, Wen-Li Wu
Fabricating mechanically robust polymer structures with nanoscale dimensions is critical for a wide range of emerging technologies. The rigidity of such structures is expected to change as the feature sizes approach the characteristic dimensions of the

Resistivity of Nanometer-Scale Films and Interconnects: Model and Simulation

October 20, 2005
Author(s)
Emre Yarimbiyik, Harry A. Schafft, Richard A. Allen, Mona Zahgoul, David L. Blackburn
We have developed a highly versatile simulation program for examining the impact of reduced dimensions on resistivity that goes beyond the work of others, e.g. Fuchs [1] and Mayadas and Shatzkes [2]. The program can simulate the effects of surface and
