Fully automatized parallel segmentation of the optic disc in retinal fundus images
(Elsevier, 2016-11)
This paper presents a fully automatic parallel software for the localization of the optic disc (OD) in retinal fundus color images. A new method has been implemented with the Graphics Processing Units (GPU) technology. ...

Solving molecular flexible docking problems with metaheuristics: A comparative study
(Elsevier, 2015)
The main objective of the molecular docking problem is to find a conformation between a small molecule (ligand) and a receptor molecule with minimum binding energy. The quality of the docking score depends on two factors: ...

Population Dynamics P Systems on CUDA
(Springer, 2012)
Population Dynamics P systems (PDP systems, in short) provide a new formal bio-inspired modeling framework, which has been successfully used by ecologists. These models are validated using software tools against actual ...

A geometric protocol for cryptography with cards
(Springer, 2015)
In the generalized Russian cards problem, the three players Alice, Bob and Cath draw a, b and c cards, respectively, from a deck of a + b + c cards. Players only know their own cards and what the deck of cards is. Alice ...

Skeletonizing Images by Using Spiking Neural P Systems
(Fénix Editora, 2012)
Skeletonizing an image is representing a shape with a small amount of information by converting the initial image into a more compact representation and keeping the meaning features. In this paper we use spiking neural ...

A Characterization of PSPACE with Antimatter and Membrane Creation
(Fénix Editora, 2015)
The use of negative information provides a new tool for exploring the limits of P systems as computational devices. In this paper we prove that the combination of antimatter and annihilation rules (based on the annihilation ...

Matrix Representation of Spiking Neural P Systems
(Springer, 2011)
Spiking neural P systems (SN P systems, for short) are a class of distributed parallel computing devices inspired from the way neurons communicate by means of spikes. In this work, a discrete structure representation of ...

A bioinspired computing approach to model complex systems
(Springer, 2014)
The use of models is intrinsic to any scientific activity. In particular, formal/mathematical models provide a relevant tool for scientific investigation. This paper presents a new Membrane Computing based computational ...

Computation of Ramsey Numbers by P Systems with Active Membranes
(World Scientific, 2011)
Ramsey numbers deal with conditions when a combinatorial object necessarily contains some smaller given objects. It is well known that it is very difficult to obtain the values of Ramsey numbers. In this work, a theoretical ...
