      A computational modeling for real ecosystems based on P systems  [Article]

      Cardona, Mónica; Colomer, M. Angels; Margalida, Antoni; Palau, Antoni; Pérez Hurtado de Mendoza, Ignacio; Pérez Jiménez, Mario de Jesús; Sanuy, Delfí (Springer, 2011)
      In this paper, a P systems based general framework for modeling ecosystems dynamics is presented. Particularly, ecosystems are specified by means of multienvironment P systems composed of a finite number of environments, ...

      A P System Based Model of an Ecosystem of Some Scavenger Birds  [Presentation]

      Cardona, Mónica; Colomer, M. Angels; Margalida, Antoni; Pérez Hurtado de Mendoza, Ignacio; Pérez Jiménez, Mario de Jesús; Sanuy, Delfí (Springer, 2010)
      The Bearded Vulture (Gypaetus Barbatus) is an endangered species in Eu- rope that feeds almost exclusively on bone remains provided by wild and domestic ungu- lates. In [1], we presented a P system in order to study the ...

      A P System Modeling an Ecosystem Related to the Bearded Vulture  [Presentation]

      Cardona, Mónica; Colomer, M. Angels; Pérez Jiménez, Mario de Jesús; Sanuy, Delfí; Margalida, Antoni (Fénix Editora, 2008)
      The Bearded Vulture is one of the rarest raptors in Europe and it is an endangered species. In this paper, we present a model of an ecosystem related with the Bearded Vulture which is located in the Catalan Pyrenees, by ...

      Characterizing the Aperiodicity of Irreducible Markov Chains by Using P Systems  [Presentation]

      Cardona, Mónica; Colomer, M. Angels; Pérez Jiménez, Mario de Jesús (Fénix Editora, 2009)
      It is well known that any irreducible and aperiodic Markov chain has exactly one stationary distribution, and for any arbitrary initial distribution, the sequence of distributions at time n converges to the stationary ...

      Classifying States of a Finite Markov Chain with Membrane Computing  [Chapter of Book]

      Cardona, Mónica; Colomer, M. Angels; Pérez Jiménez, Mario de Jesús; Zaragoza, Alba (Springer, 2006)
      In this paper we present a method to classify the states of a finite Markov chain through membrane computing. A specific P system with external output is designed for each boolean matrix associated with a finite Markov ...

      Handling Markov Chains with Membrane Computing  [Presentation]

      Cardona, Mónica; Colomer, M. Angels; Pérez Jiménez, Mario de Jesús; Zaragoza, Alba (Fénix Editora, 2006)
      In this paper we approach the problem of computing the n–th power of the transition matrix of an arbitrary Markov chain through membrane computing. The proposed solution is described in a semi–uniform way in the framework ...

      Hierarchical clustering with Membrane Computing.  [Article]

      Cardona, Mónica; Colomer, M. Angels; Zaragoza, Alba; Pérez Jiménez, Mario de Jesús (Institute of Informatics Slovak Academy of Sciences, 2008)
      In this paper we approach the problem of hierarchical clustering through membrane computing. A specific P system with external output is designed for each Boolean matrix associated with a finite set of individuals. The ...
