Landsberg's notion of disorder, entropy normalized to maximum entropy, was originally proposed for the Shannon information-theoretic entropy to overcome extensivity-based deficiencies of entropy as a measure of disorder. We generalize Landsberg's concept to three classes of extended entropies:...

In this work, we develop an analog circuit to generate a stochastic signal with stationary distribution exhibiting a tunable power-law tail. The proposed circuit design is a variant of a recently introduced one based on a differential equation with both multiplicative and additive noises. Here,...

Here some ideas related with delayed unstable systems are exposed. In particular, two simple dynamics where antagonistic forces, one of them being a time-delayed and randomly modulated force, are presented as prototypes to study the apparency of a critical balance that is seen as a transient...

This paper builds on Kocenda (2001) and extends it in three ways. First, new intervals of the proximity parameter ε (over which the correlation integral is calculated) are specified. For these ε-ranges new critical values for various lengths of the data sets are introduced, and through Monte...

In this paper we use the “Recurrence Quantification Analysis” proposed by Zbilut and Webber (1992), to develop three test procedures that allow us to detect determinism underlying series. Based on the concept of “Percent of Determinism” we obtain three statistics that allow us to test...
