Figure 3: Computation of the misfit function between two time-shifted Ricker signal depending on the time shift, using a least-squares distance and an optimal

The dynamic of this stochastic differential equation enables us to compute the law of the hitting time of zero for the distance between the two skew Brownian motions.. This extends

The aim of the reconstruction is to determine the values of the 14 other parameters: the length and the right-end radius of the main pipe and the locations, the radii and the

Convergence of an estimator of the Wasserstein distance between two continuous probability distributions.. Thierry Klein, Jean-Claude Fort,

Control of autonomous ordinary differential equations In short, we have a method using piecewise uniform cubic B´ ezier curves to approximate optimal trajectories.. This method can

include nonlinear complex arithmetic (also known as the theory of alge- braically closed fields), using Gr¨ obner bases [9]; linear real arithmetic, using Fourier-Motzkin

Gray line is the observed mean shell length, measured on ten individuals of three-year-old great scallops collected in the Bay of Brest between 1998 and 2003 (EVECOS data base
