    • Abstract
      A reduced-order model algorithm, called ALP, is proposed to solve nonlinear evolution partial differential equations. It is based on approximations of generalized Lax pairs. Contrary to other reduced-order methods, like Proper Orthogonal Decomposition, the basis on which the solution is searched for evolves in time according to a dynamics specific to the problem. It is therefore well-suited to solving problems with progressive front or wave propagation. Another difference with other reduced-order methods is that it is not based on an off-line / on-line strategy. Numerical examples are shown for the FKPP equations and for the bidomain model of electrophysiology. This work was done in collaboration with Damiano Lombardi and Elisa Schenone.

    • Abstract
      Bayes spaces contain equivalence classes of -additive measures. Two measures are equivalent when they are proportional. These measures are represented by densities and vector space operations are dened. Probability measures and density functions are included in these spaces. When the densities are log-square-integrable, they are in a Hilbert space called B2.
      Bayes spaces and associated Hilbert spaces B2 have been developed in a theoretical way, but there is still a long way to understand the implications of the theory, as well as to develop potential applications. The talk is aimed at reviewing the theory and giving some examples of distributions for which the B2 distance can be easily obtained. These examples show the variety of distribution supports that can be dealt with the theory. An application to grain size distribution is presented. The goal is to decide whether different populations have different mean distribution.

    • Abstract
      A discretization of a computational domain is the starting point in many
      different numerical applications. Anisotropic meshes allow to obtain simulation results of similar accuracy with significantly less effort.
      TetGen offers an efficient triangular and tetrahedral data structure for robust and efficient local mesh operations. So far, all these features are employed in an isotropic framework. While they can be exploited to get anisotropic triangular or tetrahedral mesh. The key concept is the following: an anisotropic mesh corresponds to an isotropic one in a proper distorted space. Indeed, in this distorted space we may re-use all the routine developed for the isotropic case,but now, the resulting mesh will be anisotropic.
      In this talk, we present how we have developed this idea to make TetGen an
      anisotropic triangular mesh generator. More in detail, we provide two differentways used to distort the space and get anisotropic triangular meshes.

    • Abstract
      The collective response of small bubbles to external pressure changes is
      a topic of interest in various processes such the elaboration of new
      contrast agents, lithotripsy, systems involving wave propagation and
      underwater explosions.
      Modeling the influence of the smallest scales (of the order of microns
      and below) on large scales is crucial to unveil the intrinsic
      interaction mechanisms between pressure waves and the response of
      bubbles.

      In this talk I will present some recent advances on the modeling and
      simulation of complex systems containing bubbles. Based on
      volume-averaged equations, a subgrid model is added to account for a
      bubble, or multiple bubbles, within each computational cell. The model
      converges to the solution of ensemble-averaged bubbly flow equations for
      weak oscillations and monodisperse systems. In the other extreme, it also
      converges to the theoretical solution for a single oscillating bubble,
      and captures the bubble radius evolution and the pressure disturbance
      induced in the liquid. Compared to previous models based on volume and
      phase averaging, the new model extends the range of void fractions that
      can be reliably simulated and, for low enough void fractions,reproduces
      the results of the polydisperse phase-averaged model with much smaller
      computational expense. The new numerical results allow us to gain new
      insight into the effect of direct bubble-bubble interactions as well as !
      polydispersity in the response of bubble clusters.

      Finally, I will discuss some recent progress on the generalization of the
      model to more complex situations and some challenges when modeling the
      influence of nanometric bubbles at large scales.

    • Tuesday, april 21 2015 at 11:00, Aula Saleri, VI Piano Edificio La Nave Dipartimento di Matematica – Politecnico di Milano
    • Abstract
      A Saint-Venant-Exner model is deduced from an asymptotic analysis of the Navier-Stokes equations. The model is defined in terms of the mass transference between the static and the moving sediment layers. One of the improvements of this deduction is that the derived model accounts with an associated energy balance, a property that the classical SVE models do not have. Moreover, the model contains a modification to be incorporated to the gravitational term in order to take into account arbitrary sloping beds. Several numerical test will be presented in order to show such differences.
