    ABSTRACT
    We consider entire solutions $u$ to the minimal surface equation in $R^N$, with $N\ge8$, and we prove the following sharp result : if $N-7$ partial derivatives $ \frac{\partial u }{\partial {x_j}}$ are bounded on one side (not necessarily the same), then $u$ is necessarily an affine function.
  • Testing for a significance in spatial regression with functional response
    Veronika Rímalová, Palacký University Olomouc, Czech Republic – Department of Mathematical Analysis and Applications
    martedì 5 dicembre 2017 alle ore 14:30, Aula Saleri VI Piano – Edificio 14, Dipartimento di Matematica POLITECNICO DI MILANO
    ABSTRACT
    In this talk we present a problem consisting of modelling and testing for spatial functional data in the context of regression analysis. The motivating data set includes monthly measurements of 5 chemical elements taken from 5 different sites near Brno, Czech Republic. Sampling locations were selected with the purpose of testing if the sites can be divided in two parts, agricultural and forest soil, according to their chemical properties. We propose to treat the measurements taken from each sampling point as functions of time distributed in space. To test for the difference according to the soil type, we develop an interval-wise testing procedure, in a geostatistical framework. We propose to perform the tests on residuals of a spatial linear model with a functional response. We apply the proposed method to the available data and discuss the results from the geological viewpoint.

  • Numerical simulations of non-ideal compressible-fluid flows
    Alberto Guardone, Dipartimento di Scienze e Tecnologie Aerospaziali, Politecnico di Milano
    giovedì 30 novembre 2017 alle ore 14:00, Aula Consiglio VII Piano – Edificio 14, Dipartimento di Matematica POLITECNICO DI MILANO
    ABSTRACT
    In the close proximity of the liquid-vapour saturation curve and critical point, well-known thermodynamic phenomena including large compressibility and critical point effects results in very unusual fluid dynamics features, including non-ideal or rarefaction shock waves, mixed and split waves. This unconventional behaviour, which cannot occur in the ideal flow of dilute gases, is referred to as Non-Ideal Compressible-Fluid Dynamics or NICFD. The focus of this short lecture is to review the theoretical background of NICFD and to discuss the impact of highly non-ideal conditions on the design and properties of numerical schemes for compressible flows. Exemplary flow fields will be presented and compared to available experimental data from the Test-Rig for Organic VApours (TROVA) of Politecnico di Milano, a unique facility in which supersonic flows in non-ideal conditions can be measured and observed. The present results are obtained within the framework of the ERC Consolidator Grant NSHOCK, of which the presenter is the PI.

  • Motori a reazione e razzi – La propulsione nell’atmosfera e fuori di essa
    Marco Beghi, Politecnico di Milano
    mercoledì 29 novembre 2017 alle ore 15:00, Sala Consiglio VII piano, Dip. di Matematica
    ABSTRACT
    In un fluido, in assenza di un appoggio solido, la propulsione si ottiene accelerando del fluido in direzione opposta. Questo è quanto fanno le eliche, sia navali sia aeronautiche, che accelerano il fluido nel quale sono immerse. Anche i motori a reazione eiettano soprattutto aria dell’atmosfera. Per i viaggi spaziali, il movimento nel vuoto non subisce resistenze, ma richiede l’utilizzo dei razzi, che devono avere a bordo tutto il fluido che eietteranno. Questo pone dei requisiti molto stringenti alla realizzabilità dei voli, requisiti che vengono analizzati in qualche dettaglio, e che fanno sì che per l’accesso ai pianeti esterni venga utilizzato anche un altro meccanismo, la cosiddetta ‘fionda gravitazionale’.

  • Multi-scale and multi-physics modeling of complex flow and transport processes for energy storage in the subsurface
    Rainer Helmig, Department of Hydromechanics and Modelling of Hydrosystems, University of Stuttgart

    ABSTRACT
    The subsurface is being increasingly utilised both as a resource and as an energy and waste repository. Historically, there have been few issues of concern related to competition between resources, with groundwater contamination being a notable exception. However, with increasing exploitation, resource conflicts are becoming increasingly common and complex. Current issues in this regard include, for example, the long-range impact of mechanical, chemical and thermal energy storage on groundwater resources, and the complex effects surrounding hydraulic fracturing in both geothermal and shale gas production.
    To analyse and predict the mutual influence of subsurface projects and their impact on groundwater reservoirs, advanced numerical models are necessary. In general, these subsurface systems include processes of varying complexity occurring in different parts of the domain of interest. These processes mostly take place on different spatial and temporal scales. It is extremely challenging to model such systems in an adequate way, accounting for the spatially varying and scale-dependent character of these processes.
    In this seminar, we will give an overview of possible utilisation conflicts in subsurface systems and of how the groundwater is affected and review several model coupling concepts with a focus on the lecturer’s work in this field. The concepts are divided into temporal and spatial coupling concepts, where the latter are sub-divided into multi-process, multi-scale, multi-dimensional, and multi-compartment coupling strategies. We will present a large-scale simulation showing the general applicability of the modelling concepts of such complicated natural systems, especially the impact on the groundwater of simultaneously using geothermal energy and storing chemical and thermal energy. At the same time, we will show that such real large-scale systems provide a good environment for balancing the efficiency potential and possible weaknesses of the approaches discussed.
