Convective regularization for optical flow
, 2015 We argue that the time derivative in a fixed coordinate frame may not be the most appropriate measure of time regularity of an optical flow field. Instead, for a given velocity field $v$ we consider the convective acceleration $v_t + \nabla v v$ which ...

Journal of Numerical Analysis and Approximation Theory, 2003 We consider the multicriteria problem of combinatorial optimization with partial criteria of the kind MINMAX MODUL. The parameters of criteria are subject to "small" independent perturbations.

Variance Reduction Result for a Projected Adaptive Biasing Force Method
, 2017 This paper is committed to investigate an extension of the classical adaptive biasing force method, which is used to compute the free energy related to the Boltzmann-Gibbs measure and a reaction coordinate function.

On the long time behavior of stochastic vortices systems [PDF]
, 2013 In this paper, we are interested in the long-time behaviour of stochastic systems of n interacting vortices: the position in R2 of each vortex evolves according to a Brownian motion and a drift summing the influences of the other vortices computed ...

Impact of Demand-Response on the Efficiency and Prices in Real-Time Electricity Markets [PDF]
, 2014 International audienceWe study the effect of Demand-Response (DR) in dynamic real-time electricity markets. We use a two-stage market model that takes into account the dynamical aspects of gen-eration, demand, and DR. We study the real-time market prices

The Hughes model for pedestrian dynamics and congestion modelling [PDF]
, 2016 In this paper we present a numerical study of some variations of the Hughes model for pedestrian flow under different types of congestion effects. The general model consists of a coupled non-linear PDE system involving an eikonal equation and a first ...
