El Noreste de la provincia de Buenos Aires corresponde a un ambiente llano con pendientes muy bajas, donde tienen gran relevancia los movimientos verticales del agua, resultando de especial interés los procesos de recarga ya que constituyen la principal fuente…

Las perspectivas para la Ingeniería del Software (IS) y del Conocimiento (IC) conducen hacia un desarrollo conjunto que permita la construcción de sistemas que integren software convencional (SC) y software basado en conocimientos.

Alcanzado este punto, los desarrolladores de…

About fifteen years ago, the Electronic Engineering Department of the National Technological University of Buenos Aires was structured grouping the curricula in Knowledge Areas. One of them was the Digital Area. It was assumed that its contents should be changing…

The theory of satellite loss resulting from a giant impact on Uranus (Parisi and Brunini 1997, Planet. Space Sci. 45, 181–187) is revisited, in the light of the discovery of its five outer moons (Gladman et al. 1998, Nature 392,…

Knowledge acquisition for systems based on knowledge can be called knowledge engineering, according to Feigenbaum (1980) who used the term to describe the reduction of a wide context of knowledge for a set of facts and rules. The term Knowledge…

The appearance and continuous growth of virtual communities on the web imposes the challenge of coping with the large amount of information and knowledge these communities produce. The Semantic Web with its set of standards and technologies provides the basic…

Frequently we become amazed with the increasing number of problems to be solved that fiourish while facing daily activities. Often, related to these problems we llave also an incredible amount oí data. Since we cannot allways afford time and resources…

In the restricted single-machine common due date problem the goal is to find a schedule for the n jobs which jointly minimizes the sum of earliness and tardiness penalties, while for the weighted tardiness problem the goal is to find…

Argumentative formalisms have been widely recognized as knowledge representation and reasoning tools able to deal with incomplete and potentially contradictory informa- tion. All such formalisms are computationally demanding. Hence, optimizing argumen- tative systems has been approached from di erent views.

A grande maioria dos Sistemas de Gerenciamento de Aprendizagem predominantemente em uso no ensino com suporte computacional são estáticos e lineares, ou seja, apresentam o mesmo conteúdo instrucional para os diversos estudantes sem considerar o nível de aquisição de conhecimentos…
