Molhabilidade da madeira de Maçaranduba (Manilkara huberi) in natura

Redes neurais aplicadas em processos de usinagem da madeira

In order to obtain products and services to exceed the level of productivity required by the market, many machining wood factors should be optimized. The current goal of research in Artificial Intelligence is dedicated to develop intelligent flexible systems, self-adjusting, to decrease the presence of human operators. The control of these processes is done through the help of computer systems ...

Contracts with Animals: Lucretius, De Rerum Natura

Modem philosophers interested in the moral status of animals frequently debate the possibility of extending justice to animals througb a theory of social contract, witb Rawl's theory usually providing the basis of discussion. Contractualism was, of course, also an interest of ancient pbilosopbers, particularly tbe Epicureans, wbo believed that "pleasure," dermed as "freedom from anxiety," was t...

De Natura Sonoris: Sonification of Complex Data

The graphical representation of complex and multidimensional data often falls short of affording us the clear and immediate insights that graphs offer for simpler data. We believe a sonic representation could greatly enhance our ability to interpret such data. In order to be effective, this sonification needs to be intuitive, flexible and easy to learn. Our natural ability at processing speech ...

Genetic structure and mating system of Manilkara huberi (Ducke) A. Chev., a heavily logged Amazonian timber species.

In this work, we report on the population genetic structure of the endangered tree species Manilkara huberi, an Amazonian tree species intensely exploited due to the high density and resistance of its wood. We investigated the patterns of spatial distribution, genetic structure, and mating system using 7 microsatellite loci and here discuss the consequences for conservation and management of th...
