In multitarget tracking, most particle approximations have the effect that new multitarget particles are obtained by discarding or replicating globally existing multitarget particles. A better design would be to produce shuffled multitarget particles in which the particle for each different target...

This thesis is on the rigorous justification of full dispersion models in coastal oceanography. The first full dispersion model was introduced by G. Whitham in 1967 to study the Stokes waves of maximal amplitude and the wavebreaking phenomenon. It is a full dispersion modification of the Korteweg-...

We show that the geodesic flow of a compact , closed surface of genus greater than one without conjugate points and continuous Green bundles is time-preserving semi-conjugate to a continuous expansive flow acting on a compact 3-manifold. As an application , we get the uniqueness of the measure...
