Noise versus chaos in a causal Fisher-Shannon plane

We revisit the Fisher-Shannon representation plane ${\mathcal H} \times {\mathcal F}$, evaluated using the Bandt and Pompe recipe to assign a probability distribution to a time series. Several stochastic dynamical (noises with $f^{-k}$, $k \geq 0$, power spectrum) and chaotic processes (27 chaotic maps) are analyzed so as to illustrate the approach. Our main achievement is uncovering the informational properties of the planar location.Comment: 6 pages, 1 figure. arXiv admin note: text overlap with arXiv:1401.213

Markov-modulated model for landing flow dynamics: An ordinal analysis validation

Air transportation is a complex system characterised by a plethora of interactions at multiple temporal and spatial scales; as a consequence, even simple dynamics like sequencing aircraft for landing can lead to the appearance of emergent behaviours, which are both difficult to control and detrimental to operational efficiency. We propose a model, based on a modulated Markov jitter, to represent ordinal pattern properties of real landing operations in European airports. The parameters of the model are tuned by minimising the distance between the probability distributions of ordinal patterns generated by the real and synthetic sequences, as estimated by the Permutation Jensen-Shannon Distance. We show that the correlation between consecutive hours in the landing flow changes between airports, and that it can be interpreted as a metric of efficiency. We further compare the dynamics pre and post COVID-19, showing how this has changed beyond what can be attributed to a simple reduction of traffic. We finally draw some operational conclusions, and discuss the applicability of these findings in a real operational environment.Comment: 12 pages, 11 figures, 2 table

Informational Time Causal Planes: A Tool for Chaotic Map Dynamic Visualization

In the present chapter, we made a detailed analysis of the different regimes of certain chaotic systems and their correspondence with the change in the normalized Shannon entropy, Statistical Complexity, and Fisher information measure. We construct a bidimensional plane composed of the selection of a pair of the informational tools mentioned above (a casual plane is defined), in which the different dynamical regimes appeared very clear and give more information of the underlying process. In such a way, a plane composed of the normalized Shannon entropy, statistical complexity, normalized Shannon entropy, and Fisher information measure can be applied to follow the changes in the behavior variations of the nonlinear systems

From slave to saint

Jacinta, una niña de siete años, quiere buscar a su papá, pero su tía, Epimenia la esclaviza y abusa de ella. Entonces, Jacinta intenta quitarse la vida, pero Lino, un pretendiente, lo impide. Finalmente, Jacinta decide ser santa y huye detrás de su padre celestial. (Texto tomado de la fuente)Jacinta, a seven-year-old girl, wants to look for her father, but her aunt, Epimenia, enslaves and abuses her. Then, Jacinta tries to take her own life, but Lino, a suitor, prevents her. Finally, Jacinta decides to be a saint and flees after her heavenly father.MaestríaGuió

Noise versus chaos in a causal Fisher-Shannon plane

We revisit the Fisher-Shannon representation plane H × F, evaluated using the Bandt and Pompe recipe to assign a probability distribution to a time series. Several stochastic dynamical (noises with f −k , k ≥ 0, power spectrum) and chaotic processes (27 chaotic maps) are analyzed so as to illustrate the approach. Our main achievement is uncovering the informational properties of the planar location.Fil: Rosso, Osvaldo Aníbal. Instituto Tecnológico de Buenos Aires; Argentina.
