We study the mixing of vehicles on a two-lane highway in Hurricane evacuation. We present the deterministic model of … vehicular order changes by traffic mixing. The traffic mixing depends highly on the sensitivity. For high sensitivity, the …

In this paper, the transport of volume in a binary liquid mixture is theoretically investigated in three steps, with strong implications for the measurement of mutual diffusivities in non-dilute mixtures. In a first step, the velocity of volume transport is determined from the transport...

We have performed experiments of axial segregation in the Oyama's drum. We have tested binary granular mixtures during very long times. The segregation patterns have been captured by a CCD camera and spatio-temporal graphs are created. We report the occurrence of instabilities which can last...

We investigate the relationship between weak dependence and mixing for discrete valued processes. We show that weak … dependence implies mixing conditions under natural assumptions. The results specialize to the case of Markov processes. Several … contraction principle. In fact, we show the stronger result that the mixing coefficients for infinite memory weakly dependent …

Geometric beta-mixing is established under a rather strong sucient condition that rules out asymmetry and … tail dependence in the copula function. Geometric rho-mixing is obtained under a weaker condition that permits both …

In this paper, we propose a new semiparametric method for GARCH model by combining the EGARCH (1,1) model and local polynomial regression. Based on the idea of two-stage estimate, a link function is estimated by the local polynomial and then the parameters are obtained via the weighted least...
