    Auteur(s) : Colin Clothilde, Tamain Patrick, Ghendrih Philippe, Schwander Frederic, Serre Eric.
    Fiche détaillée
    An issue for Langmuir probe measurements of SOL turbulence concerns the impact of the probe itself on plasma transport. The aim of this paper is to investigate this issue with a synthetic reconstruction of Langmuir probe measurements by inserting a synthetic probe into a 2D fluid SOL turbulence (...)

    Fiche détaillée
    Non-human animals, including great apes, have been suggested to share some of the skills for planning that humans commonly exhibit. A crucial difference between human and non-human planning may relate to the diversity of domains and needs in which this skill is expressed. Although great apes (...)

    Auteur(s) : Deme El Hadji, Gardes Laurent, Girard Stephane.
    Fiche détaillée
    The extreme-value index is an important parameter in extreme-value theory since it controls the first order behavior of the distribution tail. Numerous estimators of this parameter have been proposed especially in the case of heavy-tailed distributions, which is the situation considered here. (...)

  • Functional kernel estimators of conditional extreme quantiles (2013)

    Auteur(s) : Girard Stephane, Gardes Laurent.
    Fiche détaillée
    We address the estimation of conditional quantiles when the covariate is functional and when the order of the quantiles converges to one as the sample size increases. In a first time, we investigate to what extent these large conditional quantiles can still be estimated through a functional (...)
