Mobile agent systems have received important attention in the last years as a new programming paradigm for widely distributed and heterogeneous systems. In this article, a multi-paradigm approach for the development of intelligent mobile agents is presented. It integrates both…

In this paper we show an algorithm for dynamic reconfiguration of distributed applications based on the mobile agent model. We also show that the proposed algorithm can be easily implemented in the IPL language, a language with several abstractions for…

In the last years there has been and increasing demand of a variety of logical systems, prompted mostly by applications of logic in AI, logic programming an other related areas. Labeled Deductive Systems (LDS) were developed as a flexible methodology…

Our efforts are directed towards the understanding of the coscheduling mechanism in a NOW system when a parallel job is executed jointly with local workloads, balancing parallel perfor-mance against the local interactive response. Explicit and implicit coscheduling techniques in a…

Within the context of multi-agent systems, an agent may often find itself in a position where it receives information through informants. These informants are independent agents who have their own interests and, therefore are not necessarily completely reliable. It is…

This work presents the authors investigation regarding the application of parallel processing to the design of grounding systems, comprising concrete encased electrodes. The natural parallelism of the involved tasks and the large time-consuming characteristic of sequential processing for this kind…

We present partial results of a research project in which we use boolean circuits as a parallel computation model for the expression of queries to relational databases. For that purpose, we use the well-known equivalence between First Order Logic (FO)…

The algorithmical architecture and structure is presented for the parallelization of image similarity analysis, based on obtaining multiple digital signatures for each image, in which each "signature" is composed by the most representative coefficients of the wavelet transform of the…

This work presents the development of an instantaneous messaging system, which is centered on the distributed handling of user groups. The method pro-posed for handling of groups has several distinctive characteristics: the non exis-tence of a moderator for each group,…

Evolutionary computation (EC) has been recently recognized as a research field, which studies a new type of algorithms: Evolutionary Algorithms (EAs). These algorithms process populations of solutions as opposed to most traditional approaches which improve a single solution. All these…
