ABSTRACT: In the Cerrado Biome, the internal carbon cycling, the main carbon pools size, and the fluxes intensity between carbon pools are far from to be completely understood. This study presents the main carbon pools and cycling fluxes in terrestrial…

The paper presents a case study illustrating a collaborative problem solving process in Virtual Communities of Practice. The process relies on the existence of an underlying shared knowledge base – a repository of resources, and is carried out collaboratively by…

Un atout majeur des organisations consiste en leur capacité à créer et exploiter l’information et les connaissances, capacité déterminée entre autres par les comportements informationnels. Chargés de décisions stratégiques, tactiques et opérationnelles, les cadres intermédiaires sont au cœur du processus…

In this paper, we establish a relation between an argumentation based system: Defeasible Logic Programming (DELP), and a nonmonotonic system: Reiter’s Default Logic. This relation is achieved by introducing a variant of DELP and a transformation that maps default theories…

About 10 years ago informatics teacher training did not seem to be too productive. Even though many students graduated, most of them chose well paid jobs as IT specialists rather than underpaid teacher positions in Hungary. What is then the…

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…

Given an instance of an optimization problem together with an optimal solution, we consider the scenario in which this instance is modified locally. In graph problems, e. g., a singular edge might be removed or added, or an edge weight…

RESUMO: O conhecimento sobre a distribuição granulométrica de partículas sólidas é essencial para as áreas de material de construção, mecânica dos solos, física dos solos, hidrossedimentologia, entre outras. Em geral, as técnicas utilizadas para a avaliação da distribuição granulométrica de…
