Cellular automata (CA) are discrete dynamical systems consist of a regular finite grid of cell; each cell encapsulating an equal portion of the state, and arranged spatially in a regular fashion to form an n-dimensional lattice. A cellular automata is like computers, data represented by initial...

Although many studies have addressed poverty in Brazil, very few of them have analyzed the dynamic nature of this phenomenon. In order to fill this gap, this Working Paper seeks to identify the features that determine the permanence of poverty and the downward mobility into poverty of adults in...

Although many studies addressed poverty issues, very few of then did analyze the transient or persistent nature of this phenomenon. Encouraged by this lack of dynamic poverty analyses, the objective of this paper is to evaluate which features determine the relative position and the dynamics of...

Ground-state structural transitions in finite-sized systems are studied in the Hubbard model. We use the concept of an effective temperature γ that is directly related to the interactions among electrons. We have studied all the possible clusters, with nearest-neighbour hopping, for two, three...
