In the past few years, improvements in the data acquisition technology have decreased the time interval of data gathering. Consequently, institutions have stored huge amounts of data such as climate time series and remote sensing images. Computational models to filter,…

Diferenças pontuais entre pares de bases de diferentes sequências alinhadas são o tipo mais comum de variabilidade genética. Tais diferenças, conhecidas como polimorfismos de base única (single nucleotide polymorphisms ? SNPs), são importantes no estudo davariabilidade das espécies, pois podem…

Rangelands in Kenya make up for 70% of the land and hosts 60% of its livestock population. This ecosystem is largely inhabited by nomadic pastoralists whose livelihood depents on livestock. Land subdivision, population growth, climate change, devastating droughts, land degradation…

Brachiaria brizantha cv. Piatã was released from a Brazilian breeding program of Brachiaria genus to be a new option of forage plant for use in grasslands. This cultivar has been presented interesting strategy to persist on higher temperatures and water…

Local communities are important stakeholders in resource management and conservation efforts, particularly in the developing world. Although evidence is mixed in suggesting that these resident stakeholders are optimal forest stewards, it is highly unlikely that large tracts of tropical forests…

Research, development and technological innovation (RD&I) companies promote inter- and intra-organizational interactions based on the formation of research nets. This arrangement prioritizes the use of competencies of both people and institutions, stimulating the generation of new knowledge and competencies, and…

A proposta deste trabalho é utilizar técnicas de mineração de dados (data mining), também conhecida como processo de descoberta de conhecimento em bases de dados (Knowledge Discovery in Databases, KDD), para encontrar padrões em bases de dados relacionadas com a…

The notorious advances in textual information storage need fast and effcient tools to organize, retrieve and browse this information and tools for knowledge extraction. A very interesting way to organize specific domain information is the topic taxonomy building. Moreover a…

O uso combinado do processo de desenvolvimento de sistema baseado em conhecimento com modelo de ciclo de vida espiral e a adoção de técnicas de especificação de requisitos de software nas etapas de implementação da interface do sistema baseado em…

The yearly genetic progress obtained by breeding for increased soybean yield has been considered acceptable worldwide. It is common sense, however, that this progress can be improved further if refined breeding techniques, developed from the knowledge of the genetic mechanisms…
