We consider the multispecies model described by a coupled system of diffusion?reaction equations, where the coupling and nonlinearity are given in the reaction part. We construct a semi-discrete form using a finite volume approximation by space. The full...

In this work, we present a novel strategy for the numerical solution of a coupled system of partial differential equations that describe reaction?diffusion processes of a mixture of metals and ligands that can be absorbed by a sensor or a microorganism, ...

The application of autoencoders in combination with Dynamic Mode Decomposition for control (DMDc) and reduced order observer design as well as Kalman Filter design is discussed for low order state reconstruction of a class of scalar linear diffusion-conv...

Percolation, in its most general interpretation, refers to the ?flow? of something (a physical agent, data or information) in a network, possibly accompanied by some nonlinear dynamical processes on the network nodes (sometimes denoted reaction?diffusion...

Computer simulation of normal and diseased human heart activity requires a 3D anatomical model of the myocardium, including myofibers. For clinical applications, such a model has to be constructed based on routine methods of cardiac visualization, such a...

This study investigates the sorption of heavy metallic ions (HMIs), specifically lead (Pb2+), copper (Cu2+), iron (Fe3+), nickel (Ni2+) and zinc (Zn2+), by natural zeolite (clinoptilolite). These HMIs are combined in single-, dual-, triple-, and multi-co...

The aim of this work was to investigate the adsorption performance of a highly crosslinked poly(aniline-co-benzene) (PAB) copolymeric network. This hypercrosslinked polymer (HCP) was obtained via the Friedel?Craft reaction in the presence of FeCl3 as an ...

Transport systems are marked by a strong path dependency due to habits, infrastructure, and market rigidities. This path dependency result is challenging for innovative solutions as they face unexpected barriers, but also abrupt acceleration once the bar...
