Light propagation in 2-layered turbid media that have an infinitely thick 2nd layer is studied with time-resolved reflectance. The authors used a soln. of the diffusion equation for this geometry to show that it is possible to derive the absorption and the ...
Error-diffusion is widely used to generate intensity levels between the primary levels of multi-level colour printing devices (ink-jet printers, electrophotographic printers). Standard error-diffusion algorithms produce structure artifacts at rational inte ...

A theoretical approach to the steady-state limiting current response behavior of multiple microelectrode arrays, consisting of spherical, hemispherical, disk-shaped, or hemicylindrical electrode units, is presented. An approximative treatment is given for ...
A general approximation for the solution of the one- dimensional nonlinear diffusion equation is presented. It applies to arbitrary soil properties and boundary conditions. The approximation becomes more accurate when the soil-water diffusivity approaches ...
Adsorption of cadmium (Cd) onto fine sand was investigated using batch (static) and steady flow (dynamic) experiments at pHs of 5.5, 6.0 and 6.5. For both types of experiment, adsorption of Cd onto sand was found to increase with pH. In all experiments, gr ...
Although a rigorous definition of growth-limiting substrate relies on a kinetic anal., a simple stoichiometric anal. based on the calcn. of the conversion is more applicable. Anal. of single and dual limitations is based on a simulated example for a substr ...
Batch and column experiments were conducted to study the effect of pore water velocity on the adsorption of cadmium (Cd) onto a homogeneous nonaggregated porous medium under controlled environmental conditions. A wide range (5-214 cm/hr) of pore water velo ...
Previous studies have proposed the first-order reliability method (FORM) as an approach to quantitative stochastic analysis of subsurface transport. Most of these considered only simple analytical models of transport in homogeneous media. Studies that look ...
The reduction of N2O to N2 on iron oxide under transient conditions was studied in the temperature range of 270–340°C. Six different models were used to simulate the experimental data. The conventional second-order reaction between gas phase N2O and surfac ...
This paper describes a stator flux oriented control strategy using state space controllers. The optimal determination of the different controllers parameters leads to an independent control of the stator flux and the torque. The effects of undesired offset ...
