Rationes y decimas: evidencias sobre la gestión de las sernas en el siglo XI en el Noroeste de la Península Ibérica
Autor: Javier Gómez Gómez, Iñaki Martín Viso
Publikováno v: Espacio, Tiempo y Forma. Serie III, Historia Medieval, Iss 34, Pp 359-382 (2021)
Las sernas constituyen uno de los principales espacios comunales altomedievales, pero su definición resulta esquiva. Dada la diversidad de cultivos, la clave debe encontrarse en las formas de organización y gestión. El artículo analiza cuatro cas

Analysis of Air Mean Temperature Anomalies by Using Horizontal Visibility Graphs
Autor: Javier Gómez-Gómez, Rafael Carmona-Cabezas, Elena Sánchez-López, Eduardo Gutiérrez de Ravé, Francisco José Jiménez-Hornero
Publikováno v: Entropy, Vol 23, Iss 2, p 207 (2021)
The last decades have been successively warmer at the Earth’s surface. An increasing interest in climate variability is appearing, and many research works have investigated the main effects on different climate variables. Some of them apply complex

Multiplex Visibility Graphs as a complementary tool for describing the relation between ground level O3 and No2
Autor: Ana B. Ariza-Villaverde, Eduardo Gutiérrez de Ravé, Rafael Carmona-Cabezas, Javier Gómez-Gómez, Francisco J. Jiménez-Hornero
Publikováno v: Atmospheric Pollution Research. 11:205-212
The usage of multilayer complex networks for the analysis of correlations among environmental variables (such as O 3 and N O 2 concentrations from the photochemical smog) is investigated in this work. The mentioned technique is called Multiplex Visib

Publikováno v: Fractal and Fractional, 7(1), 54 (2023)
Fractal and Fractional; Volume 7; Issue 1; Pages: 54
The multifractal relationship between reference evapotranspiration (ET0), computed by the Penmann-Monteith equation (PM), relative humidity (RH) and mean surface temperature (Tmean) was studied in the middle zone of the Guadalquivir River Valley (sou

Can complex networks describe the urban and rural tropospheric O3 dynamics?
Autor: Francisco J. Jiménez-Hornero, Ana B. Ariza-Villaverde, Rafael Carmona-Cabezas, Eduardo Gutiérrez de Ravé, Javier Gómez-Gómez
Publikováno v: Chemosphere. 230:59-66
Tropospheric ozone ( O 3 ) time series have been converted into complex networks through the recent so-called Visibility Graph (VG), using the data from air quality stations located in the western part of Andalusia (Spain). The aim is to apply this n

Publikováno v: Physica A: Statistical Mechanics and its Applications. 578:126118
In the last decades, an ever-growing number of studies are focusing on the extreme weather conditions related to the climate change. Some of them are based on multifractal approaches, such as the Multifractal Detrended Fluctuation Analysis (MF-DFA),

A sliding window-based algorithm for faster transformation of time series into complex networks
Autor: Javier Gómez-Gómez, Francisco J. Jiménez-Hornero, Eduardo Gutiérrez de Ravé, Rafael Carmona-Cabezas
Publikováno v: Chaos (Woodbury, N.Y.). 29(10)
A new alternative method to approximate the Visibility Graph (VG) of a time series has been introduced here. It exploits the fact that most of the nodes in the resulting network are not connected to those that are far away from them. This means that
