WebPS: A Web-based P System Simulator with Query Facilities
(Fénix Editora, 2005)
In this paper we present an open-source web-enabled simulator for P sys- tems. We use CLIPS embedded in C, and make the simulator available as a web application, complemented by a query language to specify the results.

Computational Complexity of Simple P Systems
(Fénix Editora, 2008)
We introduce a new class of membrane systems called simple P systems, and study its computational complexity using the classical theory. We start by presenting the knapsack problem and analyzing its space and time ...

Mutual Mobile Membranes Systems with Surface Objects
(Fénix Editora, 2009)
In this paper we introduce mutual mobile membranes with surface objects, systems which have biological motivation. In P systems with mobile membranes with surface objects, a membrane may enter or exit another membrane. ...

Information Theory over Multisets
(Fénix Editora, 2007)
Starting from Shannon theory of information, we present the case of producing information in the form of multisets, and encoding information using multisets. We compute the entropy of a multiset information source by ...

Pumps Systems of Membranes
(Fénix Editora, 2004)
The reactivity of the living cells provides the real complexity of biological systems. This paper presents a reactive P system where the rules are triggered by certain conditions, and pumps are the parallel processors ...

Encodings and Arithmetic Operations in P Systems
(Fénix Editora, 2006)
Following, we present in this paper various number encodings and operations over multisets. We obtain the most compact encoding and several other interesting encodings and study their properties using elements of combinatorics ...
