Linear functional classes over cellular automata

Autor: Anaël Grandjean, Gaétan Richard, Véronique Terrier

Publikováno v: Electronic Proceedings in Theoretical Computer Science, Vol 90, Iss Proc. AUTOMATA&JAC 2012, Pp 177-193 (2012)

Cellular automata are a discrete dynamical system which models massively parallel computation. Much attention is devoted to computations with small time complexity for which the parallelism may provide further possibilities. In this paper, we investi

A Particular Universal Cellular Automaton

Autor: Gaétan Richard, Nicolas Ollinger

Publikováno v: Electronic Proceedings in Theoretical Computer Science, Vol 1, Iss Proc. CSP 2008, Pp 205-214 (2009)

Signals are a classical tool used in cellular automata constructions that proved to be useful for language recognition or firing-squad synchronisation. Particles and collisions formalize this idea one step further, describing regular nets of collidin

Report

Asymptotic behavior of dynamical systems and cellular automata

Autor: Pierre, Guillon, Gaétan, Richard

We study discrete dynamical systems through the topological concepts of limit set, which consists of all points that can be reached arbitrarily late, and asymptotic set, which consists of all adhering values of orbits. In particular, we deal with the

A graph database is a digraph whose arcs are labeled with symbols from a fixed alphabet. A regular graph pattern (RGP) is a digraph whose edges are labeled with regular expressions over the alphabet. RGPs model navigational queries for graph database

International audience; Fishermen aim to optimize the cost and benefit ratios of their behaviourswhen exploiting resources. Over the past 60 years, their decisions havebeen driven by an increasingly complex set of variables including thegrowing inter

Unveiling the Aromas and Sensory Evaluation of Hakko Sobacha: A New Functional Non-Dairy Probiotic Fermented Drink

Autor: Sarah Suffys, Dorothée Goffin, Gaëtan Richard, Adrien Francis, Eric Haubruge, Marie-Laure Fauconnier

Publikováno v: Molecules, Vol 28, Iss 16, p 6084 (2023)

At the dawn of a food transition encouraging the consumption of healthy and sustainable non-dairy probiotic products, the development of a fermented functional drink based on Sobacha is considered. Sobacha is an infusion of roasted buckwheat seeds wi

Publikováno v: PLoS ONE, Vol 18, Iss 1, p e0279690 (2023)

Valvometry techniques used to monitor bivalve gaping activity have elucidated numerous relationships with environmental fluctuations, along with biological rhythms ranging from sub-daily to seasonal. Thus, a precise understanding of the natural activ

Extension of sand pile models, one-dimensional sand automata are an intermediate discrete dynamical system between one dimensional cellular automata and two-dimensional cellular automata. In this paper, we shall study the decidability problem of glob
