The Semantic Web purports to give computeraccessible meaning to the content of the World Wide Web. The rationale behind this project is to create an environment where all this information could be freely exchanged among diverse entities, yet retaining its…

It is interesting and important to compare, analyze and assess the alternative tools that could be used in the area of Knowledge Representation. In this paper we present a reasearch line associated to this goal: to formally establish the relation…

Although some excellent Artículo de investigacións about Lyell's work have been published, they do not explicitly deal with Lyell's biogeographical conceptions. The purpose of this paper is to analyse Lyell's biogeographical model in terms of its own internal structure. Lyell…

In the information age, knowledge leads to profits, power and success. As an ancestor of data mining, machine learning has concerned itself with discovery of new knowledge on its own. This paper presents experiment results produced by genetic algorithms in…

The development of systems with the ability to reason about change notion and actions has been of great importance for the artificial intelligence community. The definition and implementation of systems capable of managing defeasible, incomplete, unreliable, or uncertain information has…

Metacognition loosely refers to one’s “thinking about thinking” and is often defined by its accompanying skills (such as monitoring and evaluating). Despite the tendency for researchers to use metacognition as an overarching umbrella term, cognitive and educational theorists argue as…

The current state of science education in the United States is evolving to building a skills-based, rather than content-based, knowledge in its students, grades K-12. To this end, I have integrated my experience and understanding of molecular biology and educational…

Abstract: Since the discovery of conducting polymers in 1977, a new era of research work has escalated, with applications such as transistors, solar cells, logic circuits, sensors, etc. The materials can be chemically modified during their synthesis in order to…

Characterizations of the containment of a convex set either in an arbitrary convex set or in the complement of a finite union of convex sets (i.e., the set, described by reverse-convex inequalities) are given. These characterizations provide ways of verifying…

In this article we describe a novel algorithm that allows fast and continuous learning on a physical robot working in a real environment. The learning process is never stopped and new knowledge gained from robot-environment interactions can be incorporated into…
