Strategic management as an academic field of study has spanned over four decades. As an interdisciplinary subject that enjoys concurrent contributions by allied disciplines such as economics and social science, numerous industries have benefited from applying tools and concepts developed…

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…

Most neural network learning algorithms cannot use knowledge other than what is provided in the training data. Initialized using random weights, they cannot use prior knowledge such as knowledge stored in previously trained networks. This manuscript thesis addresses this problem.…

Este trabajo sintetiza en tres ámbitos algunos de los resultados de las investigaciones sobre la construcción del conocimiento de la enseñanza de las matemáticas en entornos de aprendizaje multimedia que integran espacios de interacción social en contextos b-learning. Estos ámbitos…

Au XIXe siècle, la science et le fantastique produisent le même effet chez les gens : en mettant ceux-ci en contact avec des phénomènes inouïs, ils les inscrivent dans un rapport dialectique – entre le connu et l’inconnu – qui…

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.

Instruction may be seen as the intentional creation of conditions around learning so as to facilitate the achievement of determined goals. Normally, instruction is based upon certain educational strategies. It is well accepted in the field of educational technology that…
