In the second part of the seminar, Simone Vantini will introduce a general non parametric framework for the analysis of complex data with spatial dependence based on random Voronoi tessellations of the area of investigation i.
In detail, the approach will be presented in connection to a real application dealing with the analysis of varved annually laminated sediment data from lake Kassjon in Northern Sweden. These data will be considered as an year long instance of sequentially dependent functional data possibly clustered and misaligned.
The general framework will be thus displayed in an algorithm named Bagging Voronoi K-Medoid Alignment. A comparison with simpler approaches will be also presented.
This latter comparison will show the importance of jointly dealing with clustering, misalignment, and dependence while inferring on past environmental and climate changes from this kind of data. Cozzi 55 ABSTRACT Expander graphs in general, and Ramanujan graphs, in particular, have played a major role in combinatorics and computer science in the last 4 decades and more recently also in pure math. Approximately 10 years ago a theory of Ramanujan complexes was developed by Li, Lubotzky-Samuels-Vishne and others.
In recent years a high dimensional theory of expanders is emerging.
The notions of geometric and topological expanders were defined by Gromov in who proved that the complete d-dimensional simplicial complexes are such. Ramanujan complexes were shown to be geometric expanders by Fox-Gromov-Lafforgue-Naor-Pach in , but it was left open if they are also topological expanders.
This answers Gromov's original problem, but still leaves open whether the Ramanujan complexes themselves are topological expanders. Written exam Esame scritto: L'esame si articola in due prove: La votazione ottenuta nella prova n1 non non contribuisce al voto finale.

Applying the hybid filter to the Navier-Stokes equations it is possible to obtain a new set of formally correct hybrid equations. A new approach for the Reynolds stress tensor has been proposed in which no additional equations are required. This results in a very simple and cheap hybrid method, in which the RANS contribution is used to integrate, and not to substitute, LES in the context of coarse grid.
The large majority of available approaches requires first an offline calculation and, second, solving a problem in an online phase. A particular and singular feature of the Proper Generalized Decomposition PGD is that the offline computation provides a generalized parametric solution, also referred as computational vademecum, precluding the need of solving any problem in the second phase.
Thus, user-prescribed parameters like material constants, external loads, geometry, etc.

Consequently, the online phase consists merely in a functional evaluation and therefore is very efficient from a computational viewpoint. Moreover, the generalized parametric solution can be further exploited by making use of the explicit form of the parametric dependence viz. Fourier transform, gradients for sensibilities, …. The separation in spatial dimensions and time in some cases , material and geometrical parameters allows for a drastic reduction in computational costs.

This approach is extremely efficient in different applications.Nevertheless, we remark that RANS can only provide a description of the mean quantities. In particular, we study the problem of existence of weak solutions in bounded domains, accounting for non-zero volumetric and boundary forcing terms.

For a multiple fractured horizontal well we analyze the dependence of fractures positioning and geometry to the long-term production of the well. The theoretical results are further investigated via numerical simulations based on a novel dual mixed hybridized finite element discretization.
