The aim of this work is to analyze the knowledge interchange on multi-agent systems using shared knowledge areas. The project involves the analysis and reformulation of some aspects of the Linda model, adding new model level features. This work proposes…

The aim of this paper is to present procedures and tools used for quality control and statistical analysis of high-density microarray (Affymetrix GeneChip®) to search for genes that may be differentially expressed and that may provide clues to unravel parasite…

O objetivo deste artigo é apresentar e discutir uma proposta de modelo conceitual para a criação de Colaboratórios para as redes de pesquisa da Embrapa. Os Colaboratórios são espaços virtuais de aprendizagem que, estruturados sob uma lógica sócio-interacionista e com…

In logic programs, negation-as-failure has been used both for representing negative information and for providing default nonmonotonic inference. In this paper we argue that this twofold role is not only unnecessary for the expressiveness of the language, but it also…

Mountain papaya fruits (Vasconcella pubescens) were tested for firmness with a nondestructive acoustic method for 14 days after harvest. The response of each fruit was analyzed with the Fourier transform to obtain a firmness index (FI) based on the second…

Problematic aspects of intercultural communication are considered in the context of: an increasingly internationalized market for higher education; the globalization of knowledge; the compatibility of distinct national higher education cultures; and the capacity for successful cross-cultural cooperation. This is exemplified…

Most of the current wireless sensor networks are built for specific applications, with a tight coupling between them and the underlying communication protocols. We present a more flexible architectural approach for building WSNs, in which application-specific features are decoupled from…
