A discrete Boltzmann model (DBM) is developed to investigate the hydrodynamic and thermodynamic non-equilibrium (TNE) effects in phase separation processes. The interparticle force drives changes and the gradient force, induced by gradients of macroscopic quantities, opposes them. In this paper, we… |

We perform a multiple time scale, single space scale analysis of a compressible
fluid in a time-dependent domain, when the time variations of the boundary
are small with respect to the acoustic velocity.
We introduce an average operator with respect to the fast time.
The averaged leading order… |

Controlled drug delivery from a multilayer spherical capsule is used for several therapeutic applications. Developing a theoretical understanding of mass transfer in the multilayer capsule is critical for understanding and optimizing targeted drug delivery. This paper presents an analytical… |

Graphics processing units (GPU) are currently used as a cost-effective platform forcomputer simulations and big-data processing. Large scale applications require thatmultiple GPUs work together but the efficiency obtained with cluster of GPUs is, at times,sub-optimal because the GPU features are… |

Starting from recent experimental observations of starlings and jackdaws, we propose a minimal agent-based mathematical model for bird flocks based on a system of second-order delayed stochastic differential equations with discontinuous (both in space and time) right-hand side. The model is… |

In this paper, we present the results of an experiment
aiming to compare measurements of atmospheric delay by
synthetic aperture radar (SAR) interferometry and GPS techniques
to estimates by numerical weather prediction. Maps of the
differential atmospheric delay are generated by processing a set… |
