Abstract. The dispersion equation for a single, nonreacting, nonadsorbing species is derived for incompressible, laminar flow in anisotropic porous media. Direct integration of the appropriate differential equations gives rise to a dispersion vector ψ i and a tortuosity vector τ i, both of which must be evaluated experimentally.

We call this the FJ-VoroTomo method. The FJ-VoroTomo method does not require tedious parameter tuning and can measure high-quality dispersion while maintaining horizontal resolution. More importantly, this method can quantitatively analyze the uncertainty of the measured dispersion curves.

Vertical pay dispersion is the difference in pay across different hierarchical levels within an organization (Milkovich and Newman 1996).While vertical pay dispersion may be useful in attracting, retaining, and motivating highly skilled employees (Lazear and Rosen 1981; Lazear 1995; Prendergast 1999), our study investigates a potential …

However, these simple engineering models (Gaussian, Integral) do not always correctly estimate the dispersion of gases with a density higher than air. The purpose of this paper is to present an …

To investigate the effect of a single wave on the time evolution of droplet size distributions, each experiment involves a single push of the wave plate for a half period, 0 ≤ t ≤ (2f) −1.The wave tank does not have a wave damper, so after the initial breaking, the wave remnants are reflected back and forth, as the energy is dissipated by the …

The 16 mm twin screw gave somewhat smaller particle sizes than the lab scale mixers (102 μ vs 1.7 and 1.9 μ), but dispersion in the cup and rotor mini-mixer was much poorer. Simply adding three steel balls to the cup as suggested by Maréchal et al. (Polym Networks Blends, 1997) greatly improved the dispersion (1.8 μm).

To date, however, no dispersion compensation schemes have been successfully applied to terahertz (THz) quantum cascade lasers for short and stable pulse generation in the THz range. In this work, a monolithic on-chip compensation scheme is realized for a modelocked QCL, permitting THz pulses to be considerably shortened from 16ps to 4ps.
