1. Algebraic methods for the computation of general reversible-equivariant mappings / Métodos algébricos para a obtenção de formas gerais reversíveis-equivariantes
In the global and local analysis of dynamical systems, we assume, in general, that the equations are in a normal form. In presence of symmetries, the equations and the problem domain are invariant under the group formed by these symmetries; in that case, the vector field is equivariant by the action of this group. When, in addition to the symmetries, we have

2. Simulador de meios porosos saturados elastoplasticos / Numerical simulator of saturated elastoplastic porous media
The exploration of mineral resources is growing in importance in the Brazilian economy. Since the environments in which these resources are found are becoming increasingly more complex and challenging for the production phase, currently unavailable knowledge and technologies are required to produce these reserves. In the particular well drilling and completi

3. Em busca de um algoritmo construtivo para autômatos celulares reversíveis: a abordagem das regras primitivas e derivadas
Cellular automata have been studied as computer models in many different areas. They have many properties, one of them being reversibility. Reversible cellular automata can be used, among other applications, for data compressing and encryption. Apparently, the reversible rules featured in the literature seem to have been derived through exhaustive searches i

4. Can race be erased? Coalitional computation and social categorization
Previous studies have established that people encode the race of each individual they encounter, and do so via computational processes that appear to be both automatic and mandatory. If true, this conclusion would be important, because categorizing others by their race is a precondition for treating them differently according to race. Here we report exp

5. DNA molecule provides a computing machine with both data and fuel
The unique properties of DNA make it a fundamental building block in the fields of supramolecular chemistry, nanotechnology, nano-circuits, molecular switches, molecular devices, and molecular computing. In our recently introduced autonomous molecular automaton, DNA molecules serve as input, output, and software, and the hardware consists of DNA restriction
