The need for improving software processes approximated the software engineering and artificial intelligence areas. Artificial intelligence techniques have been used as a support to software development processes, particularly through intelligent assistants that offer a knowledge-based support to software process’ activities.…

Rough Sets Theory has opened new trends for the development of the Incomplete Information Theory. Inside this one, the notion of reduct is a very significant one, but to obtain a reduct in a decision system is an expensive computing…

In the past, numerous approaches have been formulated either for approximating Pareto-optimal alternatives or supporting the decision making process with an interactive multi criteria decision aiding methodology. The article on the other hand presents an integrated system for the resolution…

Un Sistema Tutor Iteligente (STI) es una aplicación cuyo objetivo se centra en la enseñanza personalizada y su principal característica es la adaptación dinámica de la instrucción de acuerdo al perfil y actividad del alumno, para lo cual incorpora técnicas…

En este trabajo se presentan los resultados de los estudios zooarqueológicos realizados en el poblado de Nombre de Jesús (cabo Vírgenes, provincia de Santa Cruz, Argentina) establecido como parte del proyecto español de fortificación del Estrecho Magallanes a fines del…

Since its inception, the social sciences have tried to legitimate their scientific criteria so that the knowledge generated by social research is deemed valid and reliable. With this objective in mind, a series of techniques, norms, processes, rules and procedures…

This paper contributes to the empirical literature on pensions and saving by studying the influence of funded pension systems on the gross national saving rate using a sample of 48 developed and developing countries over the 1980-2004 period. To the…

Se describe la variación ontogenética del esqueleto de 13 embriones de Tupinambis merianae y 11 de Tupinambis rufescens, detectándose heterocronías entre ambas especies. Los resultados muestran que los elementos dermales (tanto del cráneo como de la cintura pectoral) osifican antes…

In the last few years, several studies have emphasized the use of ontologies as an alternative to organization of the information.
The notion of ontology has become popular in fields such as intelligent information integration, information retrieval on the Internet,…

The glacigenic boulders from the Hirnantian Don Braulio Formation of the Argentine Precordillera contain a well preserved shelly fauna allowing to a better knowledge of brachiopods and bivalves, but gastropods remain undescribed. The purpose of this paper is to give…
