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 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…

This paper describes the new features included in the Robolab 2 System, which permits the students to
work with a simulation of and industrial robot and carry out operations with the real robot through teleoperation.
Among these features, the flexibility…

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…

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…

This paper proposes a novel approach on embedding automatic parallelization in compilers. Due to an increasing popularity of multi-processor and multi-core architectures, software must take advantage of the processing power they offer and increase the level of parallelism as much…

Programming embedded devices has been historically a difficult task, involving the learning of the features of a specific device such as the assembly language of a processor. This led to the use of Java in embedded system as a way…

This paper presents a JAVA based framework for RTL modeling and simulation of digital hardware designs. After linking between object-oriented concepts and RTL models, the JAVA analogy to features found in a widely used hardware description language like Verilog is…
