Vibration of a Room-Sized Airspring-Supported Slab

Author(s)
H Amick, B Sennewald, N C. Pardue, E C. Teague, Brian R. Scace
This paper reports the results of the finite element analysis and in situ testing of a large-scale (4 m x 10 m) pneumatically isolated concrete slab. The slab

Pixel Based Absolute Topography Test for Three Flats

Author(s)
R E. Parks, Lianzhen Shao, Christopher J. Evans
We demonstrate a new method of performing the absolute three flat test using reflection symmetries of the surfaces and an algorithm for generating the rotation

Understanding Scanned Probe Oxidation of Silicon

Author(s)
John A. Dagata, T Inoue, J Itoh, H Yokoyama
A model for scanned probe microscope (SPM) silicon oxidation is presented. The model was derived from a consideration of the space-charge dependence of this

Inhibition Effectiveness of Halogenated Compounds

Author(s)
T Noto, Valeri I. Babushok, Anthony Hamins, Wing Tsang
A numerical study of the inhibition efficiency of halogenated compounds was carried out for C1-C2 hydrocarbon-air laminar premixed flames. The inhibition

Measuring Pressures With Cavity Ring-Down Spectroscopy

Author(s)
Roger D. van Zee, J P. Looney, Joseph T. Hodges
The industrial demand for sensitive and noninvasive tools with which to measure pressure has spurred the use of optical methods to make these measurements. This

Time Domain Modal Estimation

Author(s)
S Fahey, Jon R. Pratt
In a previous technical feature,2 we described some motives for performing structural dynamic tests and subsequently reviewed some frequency domain techniques

Minimization of ion micromotion in a Paul trap

Author(s)
D J. Berkeland, J D. Miller, James C. Bergquist, Wayne M. Itano, David J. Wineland
Micromotion of ions in Paul traps has several adverse effects, including alterations of atomic transition line shapes, significatn second-order Doppler shifts
