The technological success of phase-change materials in the field of data storage and functional systems stems from their distinctive electronic and structural peculiarities on the nanoscale. Recently, superlattice structures have been demonstrated to dramatically improve the optical and electrical performances of these chalcogenide based phase-change(More)
A "multi-physics" numerical model that couples a detailed electrical description with the heat equation and with a microscopic picture of the phase transition dynamics is presented. This model, implemented in a three dimensional semiconductor device solver, correctly reproduces the electronic switching effect in the amorphous chalcogenide alloy and the(More)
While there has been significant progress in the treatment of ischemic heart failure, it remains a significant health and economic problem worldwide. In this paper, we present the challenges of modelling ischemic heart failure and introduce a user-friendly software system that will be a sub-set of the Virtual Pathological Heart environment which is(More)
In the present work a new approach for the blood flow rate estimate is discussed together with the performances results on both Computational Fluid Dynamics and in vivo datasets. In the mean time the comparison of this new method against the standard one used in clinics during catheterization in Doppler based flow rate estimate is provided showing important(More)
A multiphysics model for Phase Change Memory (PCM) is calibrated on a large set of experimental data. Critical material and interface properties such as electrical and thermal resistivities and their dependence on temperature are extracted from data or fitting electrical characteristics with numerical simulations. The model is shown to match with a unique(More)
