The present volume contains a selection of papers presented at the Seventh Workshop on
Membrane Computing, WMC7, which took place in Leiden, The Netherlands, during July 17 …

Metapopulations, or multi-patch systems, are models describing the interactions and the
behavior of populations living in fragmented habitats. Dispersal, persistence and extinction …

Monodirectional tissue P systems with promoters are natural inspired parallel computing
paradigms, where only symport rules are permitted, and with the restriction of …

P systems or membrane systems provide a high level computational modeling framework
that combines the structural and dynamic aspects of biological systems in a relevant and …

We present a detector-pyramid architecture for real-time multi-view face detection. Using a
coarse to fine strategy, the full view is partitioned into finer and finer views. Each face …

This paper develops a scalable system design for the creation, and delivery over the
Internet, of a realistic voice communication service for crowded virtual spaces. Examples of …

P systems are the computational models of membrane computing, a computing paradigm
within natural computing area inspired by the structure and behaviour of the living cell. In …

The classical definition of tissue P systems includes a distinguished alphabet with the
special assumption that its elements are available in an arbitrarily large amount of copies …

This paper presents an approach to P system verification using the Spin model checker. It
proposes a P system implementation in PROMELA, the modeling language accepted by …

This paper is a first step towards a systematic evaluation of the possibilities to use
membrane computing as a modeling framework for economics. We start by a simple …
