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…

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…

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…

Acantholybas steinbaueri, a brachypterous new species, is described and illustrated from Java (Bali Island and Dammerman). The genus Acantholybas is redescribed, and a key to the four known species is provided.

Region-based memory management offers several important advantages over garbage-collected heap, including real-time performance, better data locality and efficient use of limited memory. The concept of regions was first introduced for a call-by-value functional language by Tofte and Talpin, and has…

This paper presents an object-oriented design and implementation of a software module to be used as the monitoring application for a Computer Integrated Building (CIB) in an intranet/extranet context., Sistemas Distribuidos - Redes Concurrencia - Sesión de pósters

Feature modelling is a key technique for identifying common and variable features in software (software families). The result of feature modelling is a feature model: a concise specification of product features and their relationships. Feature models have been proven to…

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…
