IMPROVEMENTS TO NIST'S AIR SPEED CALIBRATION SERVICE

September 24, 2013
Author(s)
Iosif I. Shinder, Christopher J. Crowley, Bernard J. Filla, Michael R. Moldover
We discuss five significant improvements to the Air Speed Calibration Service conducted by the National Institute of Standards and Technology (NIST): 1. Reduced-uncertainty calibrations of the secondary standard [Laser Doppler Anemometer, (LDA)] using a

Method for determining the irreversible strain limit of Nb 3 Sn wires

June 6, 2011
Author(s)
Loren F. Goodrich, Najib Cheggour, Xifeng Lu, Jolene D. Splett, Theodore C. Stauffer, Bernard J. Filla
We have defined a rigorous and reliable method for determining the irreversible strain limit of Nb 3Sn wires. The critical current (I c) is measured as a function of applied longitudinal strain (ε), I c(ε), at one magnetic field and a temperature of 4.0 K

Accelerating Scientific Discovery through Computation and Visualization

James S. Sims, John G. Hagedorn, Peter M. Ketcham, Steven G. Satterfield, Terence J. Griffin, William L. George, H A. Fowler, B A. am Ende, Howard Hung, Robert B. Bohn, John E. Koontz, Nicos Martys, Charles E. Bouldin, James A. Warren, D L. Feder, Charles W. Clark, Bernard J. Filla, Judith E. Terrill
The rate of scientific discovery can be accelerated through computation and visualization. This acceleration results from the synergy of expertise, computing tools, and hardware for enabling high performance computation, information science, and

The Effect of Thermal Shock on the Thermal Conductivity of a Functionally Graded Material

October 1, 1999
Author(s)
Andrew J. Slifka, M Packer, A Kumakawa, Bernard J. Filla, J M. Phelps, N Shimoda
We have measured the thermal conductivity of a ni20Cr / 8% yttria-partially-stabilized-zirconia functionally graded 1.1 mm thick coating on a substrate of 403 stainless steel. We measured thermal conductivity of the as-received coated specimen, then

Thermal Conductivity of Two Compositions of Yttria-Stabilized Zirconia

June 1, 1999
Author(s)
Andrew J. Slifka, Bernard J. Filla, Judith K. Stalick
The thermal conductivities of two different compositions of yttria-stabilized zirconia have been measured using an absolute, steady-state method. The measurements were made in a one-dised guarded-hot-plate apparatus from 130 C to 950 C. one material has a
