Reproductive and time periodic solutions for incompressible fluids
(2007-09)
In this article, our aims is to review some of the results that are currently available concerning the existence, uniqueness and regularity of reproductive and time periodic solutions of the Navier-Stokes equations and ...

On String Languages Generated by Spiking Neural P Systems
(Fénix Editora, 2006)
We continue the study of spiking neural P systems by considering these computing devices as binary string generators: the set of spike trains of halting computations of a given system constitutes the language generated ...

Handling Markov Chains with Membrane Computing
(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 ...

A Case Study in (Mem)Brane Computation: Generating {n2 | n 1}
(Fénix Editora, 2006)
The aim of this paper is to start an investigation and a comparison of the expressiveness of the two most relevant formalisms inspired by membranes interactions, namely, P systems and Brane Calculi. We compare the two ...

Uniform Solution to QSAT Using Polarizationless Active Membranes
(Fénix Editora, 2006)
It is known that the satisfiability problem (SAT) can be solved a semi- uniform family of deterministic polarizationless P systems with active membranes with non-elementary membrane division. We present a double improvement ...
Presentation

Spiking Neural P Systems with Extended Rules
(Fénix Editora, 2006)
We consider spiking neural P systems with spiking rules allowed to introduce zero, one, or more spikes at the same time. The computing power of the obtained systems is investigated, when considering them as number ...

Solving 3-COL with Tissue P Systems
(Fénix Editora, 2006)
In the literature, several examples of the efficiency of cell-like P systems in order to solve NP-complete problems in polynomial time can be found. Recently, various new models of tissue-like P systems have received ...
Presentation

Simulation of Recognizer P Systems by Using Manycore GPUs
(Fénix Editora, 2009)
Software development for cellular computing is growing up yielding new applications. In this paper, we describe a simulator for the class of recognizer P systems with active membranes, which exploits the massively parallel ...

Computing Backwards with P Systems
(Fénix Editora, 2009)
Searching all the configurations C′ such that produce a given configuration C, or, in other words, computing backwards in Membrane Computing is an extremely hard task. The current approximations are based in heavy hand-made ...
