Studies on the impact of Eucalyptus spp. on Brazilian soils have focused on soil chemical properties and isolating interesting microbial organisms. Few studies have focused on microbial diversity and ecology in Brazil due to limited coverage of traditional cultivation and…

Integrate and fire processes are fundamental mechanisms causing excitable and oscillatory behavior. Van der Pol [Philos. Mag. (7) 2 (11) (1926) 978] studied oscillations caused by these processes, which he called,relaxation oscillations' and pointed out their relevance, not only to…

The specific knowledge that can be found in web sites provides a source of information which should be used by language teachers and content teachers to teach students both subject matter and language at the same time. In this paper,…

This thesis focuses on how small to medium-sized management consultancies internationalise, as this is an under-researched area. Investigation focuses on
identifying the factors that facilitate international market success for these small
to medium-sized enterprises (SMEs), the challenges they encounter, and…

RESUMO: O conhecimento sobre a distribuição granulométrica de partículas sólidas é essencial para as áreas de material de construção, mecânica dos solos, física dos solos, hidrossedimentologia, entre outras. Em geral, as técnicas utilizadas para a avaliação da distribuição granulométrica de…

In this paper an adaptive fuzzy decentralized
control algorithm for trajectory tracking of robot manipulators is developed. The proposed decentralized control algorithm allows the overall closed-loop system to be stabilized while making the tracking error to be uniformly ultimately bounded…

O tema do trabalho é o processo de inovação que ocorre a partir de conhecimentos científicos produzidos na universidade. O objetivo central foi investigar a história de dois processos de inovação e desenvolver uma heurística parcial que sirva de referência…

This article proposes a method for achieving an appropriate balance between the parameters of support, precision, and simplicity during the evolution of classification rules by means of genetic programming. The method includes an adaptive procedure in order to achieve such…
