Some aspects of the synchronization in coupled maps

Through numerical simulations we analyze the synchronization time and the Lyapunov dimension of a coupled map lattice consisting of a chain of chaotic logistic maps exhibiting power law interactions. From the observed behaviors we find a lower bound for the size $N$ of the lattice, independent of the range and strength of the interaction, which imposes a practical lower bound in numerical simulations for the system to be considered in the thermodynamic limit. We also observe the existence of a strong correlation between the averaged synchronization time and the Lyapunov dimension. This is an interesting result because it allows an analytical estimation of the synchronization time, which otherwise requires numerical simulations.Comment: 4 pages, 6 figure

Produção e qualidade de frutos de cultivares de melancia em ecossistema de "terra firme" do Estado do Amazonas.

Neste trabalho, avaliaram-se diferentes cultivares de melancia e dois espaçamentos, para a produção de melancia na terra firme do Amazonas. O ensaio foi conduzido na Embrapa Amazônia Ocidental, Iranduba-AM, em Argissolo Amarelo distrófico, textura média, de junho a agosto de 2010
