  • Clogging transition of vibration-driven vehicles passing through constrictions 

    Patterson, Germán; Fierens, Pablo Ignacio; Sangiuliano Jimka, Federico; Köning, Pablo; Garcimartín, Angel; Zuriguel, Iker; Pugnaloni, Luis Ariel; Parisi, Daniel R. (2017-12)
    "We report experimental results on the competitive passage of elongated self-propelled vehicles rushing through a constriction. For the chosen experimental conditions, we observe the emergence of intermittencies similar ...
  • Simulating competitive egress of noncircular pedestrians 

    Hidalgo, R. Cruz.; Parisi, Daniel R.; Zuriguel, Iker (2017-04)
    "We present a numerical framework to simulate pedestrian dynamics in highly competitive conditions by means of a force-based model implemented with spherocylindrical particles instead of the traditional, symmetric disks. ...
  • Model selection: Using information measures from ordinal symbolic analysis to select model subgrid-scale parameterizations 

    Pulido, Manuel; Rosso, Osvaldo A. (2017)
    "The use of information measures for model selection in geophysical models with subgrid parameterizations is examined. Although the resolved dynamical equations of atmospheric or oceanic global numerical models are well ...
  • Anti-stokes Raman gain enabled by modulation instability in mid-IR waveguides 

    Sánchez, Alfredo D.; Fierens, Pablo Ignacio; Hernández, Santiago M.; Bonetti, Juan I.; Brambilla, Gilberto.; Grosz, Diego (2018-11)
    "The inclusion of self-steepening in the linear stability analysis of modulation instability (MI) leads to a power cutoff above which the MI gain vanishes. Under these conditions, MI in mid-IR waveguides is shown to give ...
  • Characterization of autoregressive processes using entropic quantifiers 

    Traversaro Varela, Francisco; Redelico, Francisco (2018-01)
    "The aim of the contribution is to introduce a novel information plane, the causal-amplitude informational plane. As previous works seems to indicate, Bandt and Pompe methodology for estimating entropy does not allow to ...
  • Infuence of bottleneck lengths and position on simulated pedestrian egress 

    Parisi, Daniel R.; Patterson, Germán (2017-01)
    "In this paper, the problem of pedestrian egress under di erent geometries is studied by means of two numerical models. The length of the bottleneck after the exit and the distance of the exit to the lateral wall of a ...
  • Active particles with desired orientation flowing through a bottleneck 

    Parisi, Daniel R.; Cruz Hidalgo, Raúl; Zuriguel, Iker (2018-12)
    "We report extensive numerical simulations of the flow of anisotropic self-propelled particles through a constriction. In particular, we explore the role of the particles’ desired orientation with respect to the moving ...
  • Redefining the role of obstacles in pedestrian evacuation 

    Garcimartín, Ángel; Maza, Diego; Pastor, José Martín; Parisi, Daniel R.; Martín Gómez, César; Zuriguel, Iker (2018)
    "The placement of obstacles in front of doors is believed to be an effective strategy to increase the flow of pedestrians, hence improving the evacuation process. Since it was first suggested, this counterintuitive feature ...
  • Performance of non-fibre based dispersion compensation for long-haul 10.7 Gbit/s DWDM transmission 

    Grosz, Diego; Maywar, D. N.; Küng, A. P.; Agarwal, A.; Banerjee, S. (2004)
    "Non-fibre based in-line dispersion compensation is employed to achieve long-haul transmission of 80 channels at 10.7 Gbit=s bit rate over 1200 km of LEAF fibre. Average system margins of more than 4 dB and small transmission ...
  • Impact of DCF properties on system design 

    Essiambre, René-Jean; Winzer, Peter; Grosz, Diego (2006)
    "The dispersion-compensating fiber is an important optical element of current and future optical networks. In this paper, we review the impact that various properties of dispersion-compensating fibers has on the performance ...
  • Uncertainty relation for the optimization of optical-fiber transmission systems simulations 

    Tolisano, T.; Callegari, Fulvio A.; Grosz, Diego; Fragnito, Hugo L.; Rieznik, Andrés (2005)
    “The mathematical inequality which in quantum mechanics gives rise to the uncertainty principle between two non commuting operators is used to develop a spatial step-size selection algorithm for the Split-Step Fourier ...
  • Stochastic resonance and brownian ratchets 

    Fendrik, Alejandro J.; Romanelli, Lilia; Perazzo, Roberto P. J. (2005)
    "We discuss the connections between Brownian ratchets (BR) and stochastic resonance (SR). We consider a periodic potential energy landscape with no left–right symmetry that is driven by an external force which can be ...
  • Order and disorder in the local evolutionary minority game 

    Burgos, Enrique; Ceva, Horacio; Perazzo, Roberto P. J. (2005)
    "We study a modification of the Evolutionary Minority Game (EMG) in which agents are placed in the nodes of a regular or a random graph. A neighborhood for each agent can thus be defined and a modification of the usual ...

    Burgos, Enrique; Ceva, Horacio; Perazzo, Roberto P. J. (2003)
    "We discuss a modification of the evolutionary minority game (EMG) in which agents are placed in the nodes of a regular or a random graph. A neighborhood for each agent can thus be defined and a modification of the usual ...

    Burgos, Enrique; Ceva, Horacio; Perazzo, Roberto P. J.; Devoto, Mariano; Medan, Diego; Zimmermann, Martín; Delbue, Ana María (2007)
    "We investigate the relationship between the nested organization of mutualistic systems and their robustness against the extinction of species. We establish that a nested pattern of contacts is the best possible one as far ...
