Transport Processes in Environments with Irregular Structure

The role of environments with extreme ecological conditions in the reductive evolutionary development processes of animal

Different groups of animals show phenotypic characters, which have been resulted by the reductive phenomena. The examples are the absence of pigmentation; dwindle of eyes in some cave-living animals, and also the absence of scale in some fishes. These characters are often leaded to evolution of new species with special adaptation that is so called "Regressive evolution". The reductive phenomena...

Nonlinear subdivision processes in irregular meshes

The present article deals with convergence and smoothness analysis of geometric, nonlinear, subdivision schemes in the presence of extraordinary points. For a certain class of stationary linear subdivision schemes we can show that if a convergent linear scheme and its nonlinear analogue meet a proximity condition, then the nonlinear scheme converges for dense enough input data. Furthermore, we ...

Evaluating transport in irregular pore networks.

A general approach for investigating transport phenomena in porous media is presented. This approach has the capacity to represent various kinds of irregularity in porous media without the need for excessive detail or computational effort. The overall method combines a generalized effective medium approximation (EMA) with a macroscopic continuum model in order to derive a transport equation wit...

Artificial Neural Network Modeling for the Management of Oil Slick Transport in the Marine Environments

Due to an increase in demand of petroleum products which are transported by vessels or exported by pipelines, oil spill management becomes a controversial issue in coastal environment safety as well as making serious financial problems. After spilling oil in the water body, oil spreads as a thin layer on the water surface. Currents, waves and wind are the main causes of oil slick transport. The...
