Complex Network Approach to the Statistical Features of the Sunspot Series [PDF]
, 2013 Complex network approaches have been recently developed as an alternative framework to study the statistical features of time-series data. We perform a visibility-graph analysis on both the daily and monthly sunspot series.

The visibility graph: A new method for estimating the Hurst exponent of fractional Brownian motion [PDF]
, 2009 Fractional Brownian motion (fBm) has been used as a theoretical framework to study real-time series appearing in diverse scientific fields. Because of its intrinsic nonstationarity and long-range dependence, its characterization via the Hurst parameter ...

Selección de cepas productoras de enzimas ligninolíticas nativas del Valle del Yaqui
Nova Scientia, 2017 Introducción: Las fibras lignocelulósicas están compuestas por tres polímeros: celulosa, hemicelulosa y lignina. El biopulpeo es un pretratamiento, previo al proceso de pulpeo físico químico, cuyo fin es lograr la deslignificación parcial del complejo ...

Horizontal Visibility graphs generated by type-I intermittency [PDF]
, 2013 The type-I intermittency route to (or out of) chaos is investigated within the Horizontal Visibility graph theory. For that purpose, we address the trajectories generated by unimodal maps close to an inverse tangent bifurcation and construct, according ...

Nonlinear dynamics of river runoff elucidated by horizontal visibility graphs [PDF]
, 2018 Horizontal Visibility Graphs (HVGs) are a recently developed method to construct networks from time series. The values of the time series are considered as the nodes of the network and are linked to each other if there is no larger value between them ...

Approximate entropy of network parameters [PDF]
, 2011 We study the notion of approximate entropy within the framework of network theory. Approximate entropy is an uncertainty measure originally proposed in the context of dynamical systems and time series.
