In this paper we study the topological structure of semantic networks based on titles of papers published in scientific journals. It discusses its properties and presents some reflections on how the use of social and complex network models can contribute to the diffusion of knowledge. The...

In this paper, the concentration of soot during controlled combustion is analyzed using two fuels: acetylene (AC) and natural gas (NG). The stability was evaluated within the spatio-temporal standards generated by the system evolution, which was based on the measuring technique known as the...

Recent studies have focused on models to simulate the complex phenomenon of evolution of species. Several studies have been performed with theoretical models based on Darwin’s theories to associate them with the actual evolution of species. However, none of the existing models include the...

Evolution of species is a complex phenomenon. Some theoretical models take into account evolution of species, like the Bak–Sneppen model that obtain punctuated equilibrium from self-organized criticality and the Penna model for biological aging that consists in a bit-string model subjected to...
