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…

Java decompilers convert Java class files to Java source. Common Java decompilers are javac-specific decompilers since they target bytecode produced from a particular javac compiler. We present work carried out on Dava, a tool-independent decompiler that decompiles bytecode produced from…

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…

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…

It is a common practice to retrieve code from an outside source, execute it and return the result to the user. During execution secure data can enter the program by user input or access of a data resource. It is…

Las tecnologías de la información y las comunicaciones han avanzado en forma notable en los últimos tiempos, siendo el paradigma de Internet el emblema de este desarrollo. Es posible hoy operar dispositivos a distancia en base a las tecnologías integradas…

Se diseña e implementa una red de datos y sensores, que permite conocer a tiempo, el estado clínico del paciente a los responsables de su cuidado en la Clínica "Durán" de Ambato. Esto busca mejorar el mecanismo de atención al…
