    Generalized mutual entropy is defined for networks and applied for analysis of complex network structures. The method is tested for the case of computer simulated scale free networks, random networks, and their mixtures. The possible applications for real network analysis are discussed

    Products that include artisan techniques in their production processes are becoming increasingly popular, not only for the experience they provide the consumer, but also for the growing social and environmental awareness that is booming and that motivates the purchase of proposals with the value that only handmade products can provide. This presents an invaluable opportunity for all the master craftsmen that Latin America has. Although it is true that some time ago their ancestral techniques were lost, it is now when the ideal opportunity for their recovery presents itself. However, there are knowledge and strategies of difficult access for these communities of artisans, which if well implemented can considerably increase the competitiveness of the products. This knowledge can be found through designers and researchers, who have access, training and the ability to transfer information to artisans so that the proposals generated are of even greater value, with the potential to penetrate the market. global.Cada vez cobran más popularidad los productos que incluyen técnicas artesanales en sus procesos de producción, no solo por la experiencia que le brindan al consumidor, también por la creciente conciencia social y ambiental que está en auge y que motiva la compra de propuestas con el valor que solo los productos hechos a mano pueden brindar.

    Effects of Interplanetary Dust on the LISA drag-free Constellation

    Full text link
    The analysis of non-radiative sources of static or time-dependent gravitational fields in the Solar System is crucial to accurately estimate the free-fall orbits of the LISA space mission. In particular, we take into account the gravitational effects of Interplanetary Dust (ID) on the spacecraft trajectories. The perturbing gravitational field has been calculated for some ID density distributions that fit the observed zodiacal light. Then we integrated the Gauss planetary equations to get the deviations from the LISA keplerian orbits around the Sun. This analysis can be eventually extended to Local Dark Matter (LDM), as gravitational fields are expected to be similar for ID and LDM distributions. Under some strong assumptions on the displacement noise at very low frequency, the Doppler data collected during the whole LISA mission could provide upper limits on ID and LDM densities.Comment: 11 pages, 6 figures, to be published on the special issue of "Celestial Mechanics and Dynamical Astronomy" on the CELMEC V conferenc

    Modulation of LISA free-fall orbits due to the Earth-Moon system

    Full text link
    We calculate the effect of the Earth-Moon (EM) system on the free-fall motion of LISA test masses. We show that the periodic gravitational pulling of the EM system induces a resonance with fundamental frequency 1 yr^-1 and a series of periodic perturbations with frequencies equal to integer harmonics of the synodic month (9.92 10^-7 Hz). We then evaluate the effects of these perturbations (up to the 6th harmonics) on the relative motions between each test masses couple, finding that they range between 3mm and 10pm for the 2nd and 6th harmonic, respectively. If we take the LISA sensitivity curve, as extrapolated down to 10^-6 Hz, we obtain that a few harmonics of the EM system can be detected in the Doppler data collected by the LISA space mission. This suggests that the EM system gravitational near field could provide an absolute calibration for the LISA sensitivity at very low frequencies.Comment: 15 pages, 5 figure

    Challenges in Complex Systems Science

    FuturICT foundations are social science, complex systems science, and ICT. The main concerns and challenges in the science of complex systems in the context of FuturICT are laid out in this paper with special emphasis on the Complex Systems route to Social Sciences. This include complex systems having: many heterogeneous interacting parts; multiple scales; complicated transition laws; unexpected or unpredicted emergence; sensitive dependence on initial conditions; path-dependent dynamics; networked hierarchical connectivities; interaction of autonomous agents; self-organisation; non-equilibrium dynamics; combinatorial explosion; adaptivity to changing environments; co-evolving subsystems; ill-defined boundaries; and multilevel dynamics. In this context, science is seen as the process of abstracting the dynamics of systems from data. This presents many challenges including: data gathering by large-scale experiment, participatory sensing and social computation, managing huge distributed dynamic and heterogeneous databases; moving from data to dynamical models, going beyond correlations to cause-effect relationships, understanding the relationship between simple and comprehensive models with appropriate choices of variables, ensemble modeling and data assimilation, modeling systems of systems of systems with many levels between micro and macro; and formulating new approaches to prediction, forecasting, and risk, especially in systems that can reflect on and change their behaviour in response to predictions, and systems whose apparently predictable behaviour is disrupted by apparently unpredictable rare or extreme events. These challenges are part of the FuturICT agenda

    From the time series to the complex networks: the parametric (dynamical) natural visibility graph

    Full text link
    We present the modification of natural visibility graph (NVG) algorithm used for the mapping of the time series to the complex networks (graphs). We propose the parametric natural visibility graph (PNVG) algorithm. The PNVG consists of NVG links, which satisfy an additional constraint determined by a newly introduced continuous parameter - the view angle. The alteration ofview angle modifiesthe PNVG and its properties such as the average node degree, average link length of the graph as well as cluster quantity of built graph etc. Wecalculated and analyzed different PNVG properties depending on the view angle for different types of the time series such as the random (uncorrelated, correlated and fractal) and cardiac rhythm time series for healthy and ill patients. Investigation of different PNVG properties shows that the view angle gives a new approach to characterize the structure of the time series that are invisible in the conventional version of the algorithm. It is also shown that the PNVG approach allows to distinguish, identify and describe in detail various time series.Comment: 13 pages, 6 figure

    El estudio tuvo una duración de 2 meses, tomando datos desde el día en que se destetaron los conejos, hasta tener entre 61 y 91 días de edad. Se utilizaron 30 conejos híbridos de las razas Nueva Zelanda x California; todos machos destetados en diferentes períodos de edad (28, 35 y 42 días) y provenientes de camadas homogéneas en edades, pesos y tamaños. Todos los animales recibieron el mismo manejo desde su ingreso al estudio hasta el sacrificio. Los animales fueron alimentados únicamente con bloques nutricionales de forma cilíndrica, durante toda la etapa de engorde hasta el sacrificio. Los bloques nutricionales utilizados fueron elaborados a base de Ramié. Finalizada la etapa de engorde, se procedió a realizar el faenado de los conejos conforme iban llegando al peso de sacrificio, siendo éste de 2.04 kg de peso vivo. Ya faenados los conejos, se obtuvieron los resultados de la investigación. El diseño experimental utilizado fue completamente al azar, con tres tratamientos y cinco repeticiones para cada tratamiento, siendo la unidad experimental un conejo. Durante el estudio se registraron los datos pertinentes de peso vivo inicial, el peso diario, el consumo diario de alimento, el peso del alimento rechazado, peso vivo final y el peso de la canal para cada uno de los conejos y del promedio de cada tratamiento, esto con el fin de calcular Ganancia de peso (kg), Consumo de alimento total (kg), Conversión alimenticia (kg) y Rendimiento en canal (%
