The knowledge imperfections should be considered when modeling complex problems. A solution is to develop a model that reduces the complexity and another option is to represent the imperfections: uncertainty, vagueness and incompleteness in the knowledge base. This paper proposes…

Currently, the telecommunications management systems are powerful, however, maintain centralized and proprietary platforms, limiting this way, the growth of these telecommunications networks. This factor generates the need for scalable and open systems, stimulating the sectors of the telecommunications area to…

Este trabalho apresenta uma forma de transformar aplicações orientadas a objetos tolerantes a falhas de crash, podendo ser utilizado em um ambiente distribuído baseado em objetos que se comunicam entre si, a fim de executarem uma ação. Para garantir a…

The paper describes a framework for the implementation of an elearning system based on the Semantic Web, using software agents and Java Web Services. Hopefully we have elucidated the enormous potential of making web content machine-understandable. One of the killer…

Los lenguajes orientados a objetos son utilizados en la programación de agentes y, ge- neralmente, satisfacen muchos de sus requerimientos pero presentan inconvenientes en la representación y tratamiento de actitudes mentales. Los lenguajes lógicos permiten repre- sentar actitudes mentales en…

La utilización de bases de datos distribuidas (BDD) o de bases de datos federales o federativas (DBF) representan una solución viable para los usuarios cuando deben optar para la generación de sus sistemas de información. La utilización de estas bases…

El proceso de enseñanza y aprendizaje de los cursos iniciales de nivel superior que tienen por objeto introducir al estudiante en el diseño e implementación de algoritmos, puede ser favorecido mediante el uso de herramientas específicas que den soporten tanto…

In this paper a methodology for accesing scientific data repositories on data grids is proposed. This methodology is based on ontology specification and knowledge representation. The concept of Knowledge Perspective is introduced, as the action of applying particular scientific conjectures…

The rising complexity of distributed computer systems give reason to investigate self-organization mechanism to build systems that are self-managing in the sense of Autonomic and Organic Computing.
In this paper we propose the Artificial Hormone System (AHS) as a general…

During a system’s life cycle, new requirements or changes in the existing ones imply modifying the system. Aspect-oriented software development is a new approach to the modularization of systems, yet it does not provide mechanisms to aid the evolution of…
