On Spiral Glider-Guns in Hexagonal Cellular Automata: Activator-Inhibitor Paradigm
We present a cellular-automaton model of a reaction-diffusion excitable system with concentration dependent inhibition of the activator, and study the dynamics of mobile localiza...

A Finite Model Construction for Coalgebraic Modal Logic
In recent years, a tight connection has emerged between modal logic on the one hand and coalgebras, understood as generic transition systems, on the other hand. Here, we prove tha...

Closed-loop identification with an unstable or nonminimum phase controller
In many practical cases, the identification of a system is done in closed loop with some controller. In this paper, we show that the internal stability of the resulting model, in ...
