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
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

Topography of surfaces produced in finish hard turning using cubic boron nitride (CBN) is affected by a large number of factors including tool wear and the
First-principles calculations of transmission and reflection from Ag/Fe, Au/Fe, Cu/Co, and Cu/Ni interfaces show very strong spin dependence that differs
A simple instrument for automatically controlling the deposition rate of an electronbeam evaporator is described. The design incorporates a commercially
