A cellular automata framework to study the diffusion in single and binary solvent systems

Abstract In this work, we present a two-dimensional cellular automata (CA) model to study mass transfer by diffusion of molecules in single and binary solvent systems. The method builds on Vanag’s probabilistic cellular automata (PCA), where diffusion is simulated through stochas...

Opportunities for pathways approaches for adapting to complex climate change risks

Adaptation planning is increasingly challenged under conditions of complex climate change risks, which are characterized by the dynamic interactions between compounding hazards, cascading impacts, governance failures, and multiple drivers of vulnerabilities, producing non-linear...
