Les débats éthiques sur l’architecture ont traditionnellement abordé trois thématiques récurrentes : la beauté, la solidité et l’utilité de l’œuvre architecturale. Plus récemment, les nouvelles connaissances provenant du domaine de la gestion des projets et du développement durable ont apporté…

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…

In 1950, Tinbergen described the elicitation of offspring begging by the red spot on the bill of parent gulls, and this became a model system for behavioural studies. Current knowledge on colour traits suggests they can act as sexual signals…

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…

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…

Argumentation systems have substantially evolved in the past few years, resulting in adequate tools to model
some forms of common sense reasoning. This has sprung a new set of argument-based applications in diverse
areas.
In previous work, we defined how…

The coffee production is an economic mainstay for many countries in the world. Brazil is the world?s largest producer and exporter of coffee, being responsible for about 25% of the world production. It is well known that coffee plantations are…

The knowledge that consumers have of products and services as well as other factors serves as an indicator as to which product or store to “pick”. The products and store location add to the ease with which consumers are able…

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…
