We use a set of evoked words to define the vertices of a network. The connections between vertices are established by individuals in a population that evoke these words. The resulting graph is called an Evoked Words Network, EWN. The data of evoked words comes from an epidemiological research in odontological public health. In this research we consider three concept themes or evocative words: mouth, disease, an...
Recently a multifractal object, Qmf, was proposed to allow the study of percolation properties in a multifractal support. The area and the number of neighbors of the blocks of Qmf show a non-trivial behavior. The value of the probability of occupation at the percolation threshold, p c, is a function of r, a parameter of Qmf which is related to its anisotropy. We investigate the relation between p c and the aver...
Neste trabalho desenvolvemos um programa educativo versando sobre modos normais em uma cadeia de osciladores acoplados. O usuário do programa pode simular a evolução dinâmica de uma cadeia de osciladores escolhendo condições iniciais tanto em coordenadas cartesianas como em coordenadas normais. Focalizamos o efeito do desacoplamento do sistema de equações diferenciais (passagem de coordenadas cartesianas para c...
