Low-Frequency Impedance Calibrations at NIST

Author(s)
Andrew D. Koffman, Yui-May Chang
This paper presents an overview of the low-frequency impedance measurement services offered through the Impedance Calibration Laboratory (ICL) at the National

Evaluating Evaluation Measure Stability

Author(s)
C E. Buckley, Ellen M. Voorhees
This paper presents a novel way of examining the accuracy of the evaluation measures commonly used in information retrieval experiments. It validates several of

A Nanocomposite Poly(Methyl-Methacrylate) Bone Cement

Author(s)
A H. Gomoll, A Bellare, W Fitz, T S. Thornhill, R D. Scott, P R. Jemian, Gabrielle G. Long
Poly(methyl methacrylate) (PMMA) based orthopaedic bone cements contain 1-3 micro υ size radiopacifier particles. Incomplete dispersion of these particles leads

1-cm Collimated Source for Use in Infrared Calibrations

Author(s)
Beverly Klemme, Timothy M. Jung, Adriaan C. Carter, Eric L. Shirley, Steven R. Lorentz, Raju V. Datla
A 1 cm collimated source has been developed and tested for calibration of detectors in the 2 m to 8 m range. This source will be used to calibrate the Transfer

CollabLogger: A Tool for Visualizing Groups at Work

Author(s)
Michelle P. Steves, Emile L. Morse
The CollabLogger is a visual tool that has been developed to support usability analyses of human-computer interaction in a team environment. The participants in

AlGaAs Composition Measurements from In Situ Optical Reflectance

Author(s)
Kristine A. Bertness, J T. Armstrong, Ryna B. Marinenko, Larry Robins, Albert J. Paul, Joseph G. Pellegrino, Paul M. Amirtharaj, Deane Chandler-Horowitz
We measure the composition of AlGaAs layers during epitaxial crystal growth using in situ normal-incidence optical reflectance supported by independent methods

Computation of Causal Characteristic Impedances

Author(s)
Dylan F. Williams, Ronald C. Wittmann
We develop a numerical method of determining the magnitude of characteristic impedance required by causal power-normalized circuit theories from its phase using
