Title: Some illustrative examples of permutability of fuzzy operators and fuzzy relations
Abstract: Composition of fuzzy operators often appears and it is natural to ask when the order of composition does not change the result. In previous papers, we characterized permutability in the case of fuzzy consequence operators and fuzzy interior operators. We also showed the connection between the permutability of the fuzzy relations and the permutability of their induced fuzzy operators. In this work we present some examples of permutability and non permutability of fuzzy operators and fuzzy relations in order to illustrate these results.2014-01-01T00:00:00Z¿Tesis doctorales en Open Access?

Title: Complete Synchronization between Hiperchaotic Space-Time Attractors
Abstract: Many dynamical processes that occur in nature or in experiments are
space-time bifurcations in systems with symmetries. One of the most
outstanding examples of such bifurcations is the Takens-Bogdanov bi-
furcation [1] that has been used to model Codimension-two bifurcations
with double zero eigenvalues and square symmetries, that exhibit chaotic
behavior [2, 3]. In particular, the dynamics of termo-convective experi-
ments in square cells with a small aspect ratio have been modeled with
the groups of symmetry Z2 [4] and D4 [5].
In the first part of this work we describe the dynamic behavior appear-
ing in the equation system with the group of symmetry D4 proposed in
[2], as a function of the different parameters. The space of parameters
is analyzed in order to identify those variables that could be useful to
synchronize, in space and time, two identical systems of this kind. In
the second part we describe the first results obtained to synchronize two
identical systems.2007-09-10T00:00:00Z
