Phonon dispersion curves for niobium
Journal of Physics F: Metal Physics, 1980A previously propose phenomenological screened-shell model is extended to include the tangential component of a two-body of between nearest and next-nearest ion-cores and a second-nearest-neighbour radial shell force. The resulting model contains nine parameters, three of which are obtained from the elastic constants, three from the experimental values

Phonon dispersion curves of Ba0.6K0.4BiO3
Physica C: Superconductivity, 1994Abstract The lattice dynamics of Ba 0.6 K 0.4 BiO 3 was investigated inelastic neutron scattering on a superconducting single crystal (T c =26 K (midpoint)). The results were analysed on the basis of a shell model including free carrier screening and a term to account for a breathing deformability of the BiO 6 octahedra.

Surface-phonon dispersion curves of TiC(100)
Physical Review B, 1987The surface-phonon dispersion curves of the TiC(100) surface along both the \ensuremath{\Gamma}\ifmmode\bar\else\textasciimacron\fi{} M\ifmmode\bar\else\textasciimacron\fi{} and \ensuremath{\Gamma}\ifmmode\bar\else\textasciimacron\fi{} X\ifmmode\bar\else\textasciimacron\fi{} azimuths of the two-dimensional Brillouin zone have been measured by electron ...

The splitting of dispersion curves for the fluid-loaded plate
The Journal of the Acoustical Society of America, 1995The splitting of the free-wave dispersion curve for a fluid-loaded plate into sub- and supersonic branches, and the apparent ‘‘repulsion’’ of these two branches, is discussed.

Phonon dispersion curves for palladium
Journal of Physics F: Metal Physics, 1980A previously proposed six-parameter phenomenological screened shell model is applied to the calculation of the phonon dispersion curves of palladium. The resulting fit, for all symmetric branches except the (111)T, is as good as or better than a seven-parameter calculation using Krebs' model (1965) extended to include two-body forces to third ...

The phonon dispersion curves of copper
Journal of Physics F: Metal Physics, 1975A previously proposed six parameter phenomenological screened shell model is applied to the calculation of the phonon dispersion curves of copper. Three of the six parameters are determined from the elastic constants and the remaining three from a fit to the experimental phonon dispersion curves.

Spatially Varying Dispersion to Model Breakthrough Curves
Groundwater, 2010Often the water flowing in a karst conduit is a combination of contaminated water entering at a sinkhole and cleaner water released from the limestone matrix. Transport processes in the conduit are controlled by advection, mixing (dilution and dispersion), and retention‐release.
