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.…

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.

The etiology and epidemiology of Pythium root rot in hydroponically-grown crops are reviewed with emphasis on knowledge and concepts considered important for managing the disease in commercial greenhouses. Pythium root rot continually threatens the productivity of numerous kinds of crops…

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…

El presente trabajo aborda el conocimiento; relaciones, representaciones y valoraciones que alumnos y docentes realizan en el contexto de la cotidianeidad escolar, integrando el proyecto de investigación "Adolescencia y Escuela" que se viene implementando desde 1995, en la cátedra Fundamentos…

Cultural resources like traditional medicinal knowledge need to be recognized in their role tied to important regional practices in Zimbabwe. This is especially as a nexus of legal definitions for biological, intellectual and cultural resources will inform a National Sui…

This dissertation addresses the issues pertaining to composite products (CPs). CPs are defined as products formed by combining knowledge from two distinct domains, for example, digital cameras, which combine knowledge from digital products and cameras. The three research questions addressed…

Determining an optimal schedule to minimize the completion time of the last job abandoning the system (makespan) becomes a very difficult problem when there are more than two machines in the flow shop. Due both to its economical impact and…
