Ensuring environmental sustainability is the aim of the seventh Millennium Development Goal (MDG7). United Nations data shows insufficient progress, especially in developing countries. In order to generate new information about this progress and the main barriers that hinder it, we…

This work extends the semantics and implementation of fuzzy prolog presented in [VGM02] in order to include Default Knowledge capability. The new semantic allows non-uniform default assumptions and has Closed World Assumption (CWA) and Open World Assumption (OWA) as particular…

La presente Tesis Doctoral tiene como objetivo general el empleo de sistemas sensoriales de visión y fuerza conjuntamente para realizar el guiado de robots en aquellas tareas en las que no solo se requiere controlar la trayectoria del robot sino…

In recent years, researchers in artificial intelligence have become interested in replicating human physical reasoning talents in computers. One of the most important skills in this area is predicting how physical systems will behave. This thesis discusses an implemented program…

This paper describes a system for the computer understanding of English. The system answers questions, executes commands, and accepts information in normal English dialog. It uses semantic information and context to understand discourse and to disambiguate sentences. It combines a…

Se estudian diversos aspectos del comportamiento malacofágico de Rattus rattus L. en dos
zonas de nidificación arbórea del litoral mediterráneo español. Los temas tratados se refieren a
la composición cualitativa y cuantitativa de su dieta malacológica, las técnicas de predación…

All intelligence relies on search --- for example, the search for an intelligent agent's next action. Search is only likely to succeed in resource-bounded agents if they have already been biased towards finding the right answer. In artificial agents, the…

A pesar del progreso que se realiza en el Procesamiento del Lenguaje Natural (PLN) aún estamos lejos de la Comprensión del Lenguaje Natural. Un paso importante hacia este objetivo es el desarrollo de técnicas y recursos que traten conceptos en…

Resumo: Esta pesquisa analisa o fluxo de informações da Embrapa Meio Ambiente, sob a ótica da gestão do conhecimento. Trata-se de um estudo de caso de natureza qualitativa. Tem por objetivo discutir o processo de comunicação interna e externa, na…

This paper demonstrates that it is possible to generate a reasonably accurate coordinate system on randomly distributed processors, using only local information and local communication. By coordinate systems we imply that each element assigns itself a logical coordinate that maps…
