P systems have parallel structures; therefore, parallel tools like graphic processing units (GPU) are needed to extract this parallelism. In previous approaches each membrane was assigned to one thread block. This was inefficient when the number of objects inside each membrane was low. In the proposed approach objects of the membranes are represented as entries of a matrix. Then this matrix can be...
Membrane computing and grammatical inference are two interesting areas of research with formal languages as objects of investigation. The connection between these two areas is in its infancy. In this paper we define a subclass of pattern languages called strictly pattern languages and a P system generating it. We then provide an algorithm to learn this P system.
Corner Detection is a well known problem in Digital Imagery. In this paper we present a novel approach to detect corners in digital images. In particular, in the framework of Membrane Computing, given a 2D-image, we have designed a theoretical algorithm to solve a type of the corner detection problem, using tissue-like P systems with promoters. Finally, we show some examples of how this algorithm...
In this paper we define contextual iso-triangular array P system that make use of iso-array objects and contextual iso-array rules. We examine the generative power of contextual iso-triangular array P system.
P system is a distributed and parallel computing model in membrane computing, processing multisets of symbol objects in a localized manner. This computational model has proved to be a robust framework for modelling a variety of situations arising in very different areas, for instance, investigation of problems related to digital images. In this paper, we develop a P system for handling region-based...
Y. Suzuki and H. Tanaka have developed a molecular computing model, Artificial Cell System (ACS) with elementary membrane and hierarchically structurable membranes. A chemical analysis based on kinetic spectro photometric studies on the catalytic activities of iron (III) - salen ion for H2O2 oxidation of organic sulfides and sulfoxides was proposed by A.M.I. Jayaseeli and S. Rajagopal. In this present...
H array splicing system is an effective extension of splicing operation to images. A special class of these H array splicing system allowing only simple splicing rules is also considered. Test tube array system for picture generation has also been studied based on the splicing operations. Motivated by these models here we introduce and investigate a new generative model called Simple Test Tube Array...
Computational topology within the context of digital imagery has gained a considerable role in several applications like structural pattern recognition and digital image processing. Membrane computing, which is a new computational model inspired from the structure and functioning of biological cells, has been adapted as a rich framework for handling many problems. In this paper, we present a membrane...
We introduce new P system models, called as external and internal parallel contextual array P systems, based on the external and internal parallel contextual array grammars. We can generate rectangular arrays using these P system models with the help of external or internal parallel row and column contextual array rules. We discuss some properties of these P systems and compare them with certain other...
Membrane Computing (MC) with its variants has proved to be a versatile class of distributed parallel computing model. This is because despite its infancy, it has enjoyed significant application in various fields. However, much is yet to be accomplished in the area of information and network security. So, to further explore the efficacy of MC, this paper presents a new attempt in the application of...
