Metrics used on development of expert systems is not a well investigated problem area. This article suggests some metrics to be used to measure the maturity of the conceptualization process and the complexity of the decision process in the problem…

Searching for information in databases or on the world wide web to enhance our knowledge has become an everyday task. The internet is a major source of information for education. When we want to make new material available in digital…

Although current literature on learning styles shows that matching a teacher’s instructional style with the learning styles of students affects performance in a classroom environment, little is known about the influence of learning styles in online interaction. The paper argues…

O processo de Descoberta de Conhecimento em Bancos de Dados Geográficos (DCBDG) busca encontrar padrões, informações e relacionamento espacial implícitos em dados descritivos e espaciais armazenados em bancos de dados geográficos. Este tipo de descoberta é muito importante para o…

Much Learning is done by way of studying precedents and exercises. A teacher supplies a story, gives a problem, and expects a student both to solve a problem and to discover a principle. The student must find the correspondence between…

“La tecnología KDD está basada en un bien definido proceso KDD de múltiples pasos, para el descubrimiento de conocimiento en grandes colecciones de datos. El proceso KDD es iterativo por naturaleza, y depende de la interacción para la toma de…

ABSTRACT: The paper presents the experience acquired through the use of an internet portal as a divulgation media and to support the Information Management (UM) for the project "Brazilian Rocks as Alternative Sources of Potassium". It's described the portal creation,…

This paper describes an adaptive and autocalibrated method to track surfaces. To do so, a non time
dependent impedance control system is proposed. This method fuses visual and force information to track a
given trajectory maintaining the contact with the…

Combining numerical techniques with ideas from symbolic computation and with methods incorporating knowledge of science and mathematics leads to a new category of intelligent computational tools for scientists and engineers. These tools autonomously prepare simulation experiments from high-level specifications of…
