Wave-front or surface errors may be divided into rotationally symmetric and nonrotationally symmetric terms. It is shown that if either the test part or the...
Standard leaks or leak artifacts are used extensively in industrial and research environments, typically for the calibration of helium leak detectors. The most...
A significant benefit of using standards is that standards ease the migration from one computing environment to another. But what happens when the migration if...
Many semiconductor processes require that stable and known flows of gas be delivered to the processing chamber. The thermal mass flow meter (TMFM) is used almost...

We reconstruct the density matrices and Wigner functions for various quantum states of motion of a harmonically bound 9Be+ ion. We apply coherent displacements...
An algorithm for the tomographic reconstruction of the individual moments of the probaility density functions describing the local transmittance of radiation...
Quantitative experimental measurements of soot concentrations and soot scattering are presented for a series of steady and flickering coflowing methane, propane...

Laser-focusing of atoms has emerged as a viable form of nanofabrication. Structures are formed by focusing chromium atoms as they deposit onto a surface. The...
Since the 1980''s, the European Community (EC) has established a unified Rockwell C hardness (HRC) scale by averaging several national scales, which come from...

We report experimental rate coefficients for the energy-pooling collisions Cs(6P/sub 1/2/)+Cs(6P/sub 1/2/) to Cs(6S/sub 1/2/)+Cs(nl/sub J''/) and Cs(6P/sub 3/2/...
The existence of a transition from soliton-like motion to spatially and temporally disordered motions in a periodic structure with buckling nonlinearity is...
