Correlation Charts for Ultraviolet-Visible Spectrophotometry

October 31, 2005
Author(s)
Thomas J. Bruno, Paris D. Svoronos
This section provides correlation charts and operational information for the design and interpretation of ultraviolet spectrophotometric (UV-Vis) measurements. While UV-Vis. is perhaps not as information-rich as infrared or nuclear magnetic resonance, it

Infrared Spectrophotometry

October 31, 2005
Author(s)
Thomas J. Bruno, Paris D. Svoronos
In this chapter, we present a series of correlation charts to aid in the interpretation of infrared spectra, and in performing infrared spectroscopic measurements. The correlation charts represent the characteristic absorptions that are produced by

Microfabricated Atomic Magnetometers

October 31, 2005
Author(s)
P Schwindt, John E. Kitching, Leo W. Hollberg, Svenja A. Knappe, V Shah, Li-Anne Liew, John Moreland
Using the techniques of microelectromechanical systems, we are developing chip-scale atomic sensors based on laser excitation of alkali atoms. Recently, we demonstrated a magnetometer physics package that had sensitivity of 50 pT / Hz1/2 at 10 Hz, had a

Nuclear Magnetic Resonance Spectroscopy

October 31, 2005
Author(s)
Thomas J. Bruno, Paris D. Svoronos
This section provides correlation charts and operational information for the design and interpretation of nuclear magnetic resonance (NMR) measurements.

Planning Report 05-2: IPv6 Economic Impact Assessment

October 31, 2005
Author(s)
Gregory C. Tassey
This report presents estimates of the costs and benefits associated with transitioning from Internet Protocol Version 4 (IPv4) to Internet Protocol Version 6 (IPv6). Cost estimates are based on likely development and deployment scenarios provided by

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
