A fully implicit method for diffusion-controlled solidification of binary alloys
(Elsevier, 1992-05)
A recently developed numerical method for single-component phase-change problems is extended to treat some existing multi-domain models for diffusion-controlled solidification of binary alloys. The multi-domain models ...
Direct, high resolution, four‐dimensional measurements of the fine scale structure of Sc≫1 molecular mixing in turbulent flows
(The American Institute of Physics, 1991-05)
Results from highly resolved, four‐dimensional measurements of the fine structure of the fully space‐ and time‐varying Sc≫1 conserved scalar field and the associated scalar energy dissipation rate field in a turbulent flow ...
Population distributions in the vibrational deactivation of benzene and benzene-d6. First and second moments derived from two-color infrared fluorescence measurements
(Elsevier, 1993-09-01)
Time-resolved two-color infrared fluorescence (IRF) from highly vibrationally excited benzene and benzene-d6 has been used to determine means and variances of the excited molecule population distributions over the majority ...
An Auxiliary RF Channel with Convenient Phase Control for NMR Spectrometers
(Elsevier, 1993-09)
Kinetics and fractal properties of the random sequential adsorption of line segments
(IOP Publishing Ltd, 1990-11-07)
The random sequential adsorption (RSA) of infinitely-thin line segments is studied by computer simulation. It is shown that the exponent for the time dependence of the surface coverage increases beyond the value 0.33, ...
Large scale surface structure formed during GaAs (001) homoepitaxy
(The American Institute of Physics, 1994-02-14)
Atomic force microscopy studies have been performed on GaAs (001) homoepitaxy films grown by molecular beam epitaxy. Multilayered features are seen to evolve when the growth conditions favor island nucleation. As the ...
Linear and nonlinear computations of the 1992 Nicaragua earthquake tsunami
(Birkhäuser-Verlag; Birkhäuser Verlag ; Springer Science+Business Media, 1995-09)
Numerical computations of tsunamis are made for the 1992 Nicaragua earthquake using different governing equations, bottom frictional values and bathymetry data. The results are compared with each other as well as with the ...
Universality in the Thomas-Fermi-von Weizsäcker model of atoms and molecules
(Springer-Verlag, 1990-05)
We study the Thomas-Fermi-von Weizsäcker theory of atoms and molecules. The main result is to prove universality of the structure of very large atoms and molecules, i.e., proving that the structure converges as the nuclear ...
Dynamics of excimer laser‐ablated aluminum neutral atom plume measured by dye laser resonance absorption photography
(The American Institute of Physics, 1991-04-15)
We report the first dye laser resonance absorption photographs of a single species of aluminum ground‐state neutral atoms in the plume ablated from solid aluminum by KrF excimer laser radiation. Aluminum ground‐state neutral ...
