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. ...

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 ...

Recognizer P Systems with Antimatter
(Romanian Academy, Section for Information Science and Technology, 2015)
In this paper, we consider recognizer P systems with antimatter and the in uence of the matter/antimatter annihilation rules having weak priority over all the other rules or not. We rst provide a uniform family of ...

Solving the ST-Connectivity Problem with Pure Membrane Computing Techniques
(Springer, 2014)
In Membrane Computing, the solution of a decision problem X belonging to the complexity class P via a polynomially uniform family of recognizer P systems is trivial, since the polynomial encoding of the input can involve ...

Studying the Chlorophyll Fluorescence in Cyanobacteria with Membrane Computing Techniques
(Fénix Editora, 2013)
In this paper, we report a pioneer study of the decrease in chlorophyll uorescence produced by the reduction of MTT (a dimethyl thiazolyl diphenyl tetrazolium salt) monitored using an epi uorescence microscope coupled ...

The Pole Balancing Problem with Enzymatic Numerical P Systems
(Fénix Editora, 2015)
Pole balancing is a control benchmark widely used in engineering. It involves a pole a xed to a cart via a joint which allows movement along a single axis. In this problem, the movement of the cart is restricted to the ...

PBIL for Optimizing Hyperparameters of Convolutional Neural Networks and STL Decomposition
(Springer, 2020)
The optimization of hyperparameters in Deep Neural Net-works is a critical task for the final performance, but it involves a high amount of subjective decisions based on previous researchers’ expertise. This paper presents ...

Solving SAT with Antimatter in Membrane Computing
(Fénix Editora, 2015)
The set of NP-complete problems is split into weakly and strongly NP- complete ones. The di erence consists in the in uence of the encoding scheme of the input. In the case of weakly NP-complete problems, the intractability ...

On The Semantics of Annihilation Rules in Membrane Computing
(Fénix Editora, 2015)
It is well known that polarizationless recognizer P systems with active membranes, without dissolution, with division of elementary and non-elementary membranes, with antimatter and matter/antimatter annihilation rules ...

Self-constructing Recognizer P Systems
(Fénix Editora, 2014)
Usually, the changes produced in the membrane structure of a P system are considered side effects. The output of the computation is encoded as a multiset placed in a specific region and the membrane structure in the ...
