The aim of this article is the formalization of inflection process for the Romanian language using the model of P systems with cooperative string replication rules, which will make it possible to automatically build the morphological lexicons as a base for different linguistic applications.
Ambient calculus is a theory which deals with mobile computing and computation and encompasses such notions as mobile agents, the ambients where the agents interact and the mobility of the ambients themselves. P systems is a formalism which abstracts from the structure and functioning of living cells and describes distributed parallel computing devices with… (More)
This article describes the Romanian lexical resources containing morphological data and dictionaries: synonyms, The inflection process at the creation of morphological resources based on the functional grammar with scattered context is considered. An arbitrary word is inflected knowing only its part of speech, and the gender for nouns. New words were… (More)
The aim of this article is to describe the process of determining the inflectional group using P systems with replications. In this process firstly the sets of endings of the same length are constructed, to which inflectional models are put into correspondence. Based on these endings the inflectional model for arbitrary word is determined.
In this paper we propose a new approach to express the components of continuous-time P systems throughout the components of descriptive rewriting timed Petri nets. We introduce the notion of macronode, which maps a subnet, to modify dynamically the rewriting timed Petri nets structure. A macronode is specified by a marking-controlled descriptive expression.… (More)
We describe the investigations on natural computing in the Institute of Mathematics and Computer Science of the Academy of Sciences of Moldova during last fifteen years. Most of these investigations are inspired by results and ideas belonging to Corresponding Member of the Romanian Academy Gheorghe P˘ aun.
Evolution of the informatization notion (which assumes automation of majority of human activities applying computers, computer networks, information technologies) towards the notion of Global Information Society (GIS) challenges the determination of new paradigms of society: automation and intellectualization of production, new level of education and… (More)
In this paper a bistable self-organizing genetic structure with two alternative stable states (true and false) – one-dimensional molecular-genetic trigger (1D MGT) – is modeled with Timed Hybrid Petri Nets. It has been proved that the gene expression regulation process of lexA recA genetic systems with regulatory enzymes is controlled by 1D MGT. 1D MGT can… (More)
