To determine why something has stopped working, it's helpful to know how it was supposed to work in the first place. This simple fact underlies recent work on a number of systems that do diagnosis from knowledge about the internal…

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…

The need for robust and easily extensible systems for word sense disambiguation coupled with successes in training systems for a variety of tasks using large on-line corpora has led to extensive research into corpus-based statistical approaches to this problem. Promising…

At a time when it is clear that climate change adaptation and mitigation are failing, this book examines how our assumptions about (valid and usable) knowledge are preventing effective climate action. Through a cross-disciplinary, empirically-based analysis of climate science and…

A key problem in model-based object recognition is selection, namely, the problem of isolating regions in an image that are likely to come from a single object. This isolation can be either based solely on image data (data-driven) or can…

O objetivo do trabalho é avaliar e comparar indicadores ambientais associados aos recursos hídricos entre distintos sistemas de uso da terra, desde campo e oresta natural passando por sistemas agrosilvopastoril (uma modalidade de sistema agro orestal) e silvicultural até o…

RESUMO - Estudos de longa duração em bacias hidrográ cas experimentais e representativas de uma determinada condição são importantes para um melhor entendimento da dinâmica dos processos e da resposta hidrológica de bacias a eventos diversos, gerando conhecimentos e/ou tecnologias…

O estudo tem como propósito analisar as representações de agricultoras, esposas de assentados, em relação à organização espacial na conformação do Assentamento Mato Grande, em Corumbá, MS. O assentamento rural foi criado em 1988, e foram assentadas 50 famílias, sendo…

Melipona marginata is an endangered species of stingless bee from Brazil that produces honey with particular physicochemical features and a remarkable exotic flavor. To the best of our knowledge, this is the first report devoted to exploring the medicinal potential…

The preservation, management, and sharing of indigenous knowledge is crucial for social and economic development in ruralAfrica. The high rate of illiteracy (print-based) in rural Africa and the exclusion of indigenous knowledge from Western education add to the information gap…
