    Francesco Buscemi

    • SEMINARIO
    • The theory of quantum statistical comparison with some applications to quantum information science
    • Francesco Buscemi, Nagoya University
    • Martedì 12 settembre 2017 alle ore 15:00, Aula Seminari III piano
    • Abstract
      In mathematical statistics a central role is played by the notion of statistical models (or, equivalently, statistical experiments). These objects, which can be imagined as families of probability distributions, are often used to describe the statistician’s state of knowledge about an unknown parameter. It is then natural to compare statistical models on the basis of their “information content.” This kind of problems led in the 1950s to the formulation of a whole new theory, sometimes named “statistical comparison theory,” which soon developed into a very deep field with many applications, ranging from mathematical statistics, to physics and economics. In this lecture I will present an overview of the basic ideas of statistical comparison, some possible generalizations to the quantum setting, and a few applications in quantum thermodynamics, entanglement theory, quantum measurement theory, and the theory of open quantum systems.

    • Abstract
      Stabilized methods provide a procedure to stabilize the various sources of instabilities that arise in the numerical simulation of incompressible fluid flows with reduced computational cost. It consists in adding to the standard Galerkin formulation specific terms aiming at stabilizing the possible sources of instabilities (convection dominance, pressure discretization,…). We shall describe an analysis technique for Navier-Stokes equations, in which the stability of the pressure discretization is based upon the existence of an underlying inf-sup condition between an augmented velocity space and the pressure space. We will next apply this kind of techniques to the discretization of the Primitive Equations of the Ocean. We will end by presenting an application to reduced-order modeling of turbulence.

    • Abstract
      A number of features of surgical interventions make their evaluation in randomised trials more difficult. For example, new procedures may be technically difficult to deliver so that surgical performance takes time to stabilise and outcomes may vary over time and between different surgeons. Moreover, there is a lack of trials culture among surgeons, so that efficient designs that are acceptable to the community are required. This talk will review some of the practical and technical issues involved in evaluations of surgical interventions, focusing on our work on the use of routine databases to explore learning curves, clustering between surgeons and the multiple component nature of the interventions. Some implications for design and analysis will be discussed and the limitations will be illustrated through the AMAZE trial in cardiac surgery patients who have a history of atrial fibrillation (irregular heart rhythm).

    • Abstract
      La tettonica delle placche e? il combinato di effetti secolari quali il raffreddamento della Terra e la dinamica astronomica. Quest’ultima appare il modulatore dei meccanismi e causa della polarizzazione del sistema caotico e auto-organizzato della geodinamica. Fenomeni di lungo periodo sia interni che esterni al pianeta determinano una deformazione stazionaria, intervallata da eventi semi-istantanei. Entrambe le tipologie di fenomeni rappresentano il rilascio di energia in zone dove si crea un gradiente, sia esso di pressione o temperatura. I margini di placca rappresentano l’espressione di gradienti di velocita? tra le placche, controllati da gradienti di viscosita? nel canale a bassa velocita? alla base della litosfera, a loro volta controllati da variazioni laterali della composizione chimica del mantello. Il canale a bassa velocita? e? il piano di scollamento fondamentale della tettonica delle placche e appare come la sede principale di sviluppo del magmatismo terrestre. La cinematica delle placche che possiamo ricostruire e? fortemente vincolata dalla profondita? del magmatismo. La parte pellicolare della litosfera, caratterizzata da una reologia fragile per fenomeni di alta frequenza, rilascia energia gravitazionale negli ambienti tettonici estensionali (gravimoti) e invece elastica negli ambienti trascorrenti e compressivi EelastomotiI. L’energia si accumula in volumi di crosta superiore e le faglie non sono altro che le guide d’onda lungo cui una parte di questa energia viene incanalata dai volumi e dissipata in forma elastica durante un terremoto.

    • 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.

    • 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.

    • Abstract
      This seminar will outline the workflow developed at the Laboratory of Biological Structure Mechanics – LaBS, Politecnico di Milano. (www.labsmech.polimi.it) for the investigation of cardiovascular devices. The combined in vitro and in silico approach will be applied to the study of stenting procedures of peripheral arteries in idealized and patient-specific models as well as to the study of percutaneous aortic valves, where fluid-structure interaction simulations are required. Such examples will demonstrate the extent to which performances of minimally-invasive devices are related to their design, the materials and the applied loads.
