Generalized Lattice Boltzmann Method with multi-range pseudo-potential

The physical behavior of a class of mesoscopic models for multiphase flows is analyzed in details near interfaces. In particular, an extended pseudopotential method is developed, which permits to tune the equation of state and surface tension independently of each other. The spurious velocity…

Evaluation of NOx emissions and ozone production due to vehicular traffic via second-order models

The societal impact of traffic is a long-standing and complex problem. We focus on the estimation of ground-level ozone production due to vehicular traffic. We propose a comprehensive computational approach combining four consecutive modules: a traffic simulation module, an emission module, a…

Molecular Dynamics Simulations of Nanoparticle Interactions with a Planar Wall: Does Shape Matter?

The pair correlation function of spatial Hawkes processes

We derive the pair correlation function of spatial Hawkes processes and discuss its connections with the Bartlett spectrum and other summary statistics.

Cloud Detection: An Assessment Study from the ESA Round Robin Exercise for PROBA-V

A Round Robin exercise was implemented by ESA to compare different classification methods in detecting clouds from images taken by the PROBA-V sensor. A high-quality dataset of 1350 reflectances and Clear/Cloudy corresponding labels had been prepared by ESA in the framework of the exercise.…

On the choice of retrieval variables in the inversion of remotely sensed atmospheric measurements

In this paper we introduce new variables that can be used to retrieve the atmospheric continuum emission in the inversion of remote sensing measurements. This modification tackles the so-called sloppy model problem. We test this approach on an extensive set of real measurements from the Michelson…

A discrete kinetic approximation for the incompressible Navier Stokes equations

In this paper we introduce a new class of numerical schemes for the incompressible Navier-Stokes equations, which are inspired by the theory of discrete kinetic schemes for compressible fluids. For these approximations it is possible to give a stability condition, based on a discrete velocities…

One-dimensional turbulence with Burgers

Gathering together some existing results, we show that the solutions to the one-dimensional Burgers equation converge for long times towards the stationary solutions to the steady Burgers equation, whose Fourier spectrum is not integrable. This is one of the main features of wave turbulence.
