The "Lost Guardians" of Dante's Inferno: Medium Wave Infrared Imaging Investigations of a XIV Century Illuminated Manuscript

On the occasion of the 700th centenary of the death of Dante Alighieri, medium wave infrared imaging analysis of illuminations of the XIV-century code of the Divina Commedia (MS. 1102), hosted in the Biblioteca Angelica in Rome, was performed and discussed. The investigation was carried out by means of thermographic and reflectographic techniques on illuminations where the iconographic representation appeared severely damaged.

Pinned Flexible Polymer under Oscillatory Linear Flow

The non-equilibrium structural and dynamical properties of a flexible polymer pinned to a reflecting wall and subject to oscillatory linear flow are studied by numerical simulations. Polymer is confined in two dimensions and is modeled as a bead-spring chain while the interaction with the fluid is described by the Brownian multiparticle collision dynamics. At low strain the polymer is stretched along the flow direction. When increasing strain, chains are completely elongated and compressed against the wall when the flow is reverted.

Building a Realistic Simulation of theAtmospheric State in Radiative Transfer

The simulations for the inverse problem of radiative transfer, even if built with a correct Bayesian approach, do not represent the full source of errors present in the experimental data. We point out two categories of errors (atmospheric model errors and non-Gaussian instrumental errors due to the optics and hardware, that are not considered by standard methods. Moreover, we show cases taken from FORUM simulated radiances using an End to End simulator, where se show how the instrument reacts to a non homogeneousneous filed of view.

Why diffusion-based preconditioning of Richards equation works: spectral analysis and computational experiments at very large scale.

We consider here a cell-centered finite difference approximation of the Richards equation in three dimensions, averaging for interface values the hydraulic conductivity, a highly nonlinear function, by arithmetic, upstream and harmonic means. The nonlinearities in the equation can lead to changes in soil conductivity over several orders of magnitude and discretizations with respect to space variables often produce stiff systems of differential equations.

Dopo il successo della giornata al CNR IAC di Firenze, continua il nostro viaggio nel mondo della matematica. Questa volta saranno gli studenti delle scuole secondarie superiori di Napoli a festeggiare con noi i 100 anni del CNR.

Presso la sede dell'IAC di Napoli, nell'Area della Ricerca Napoli 1 di via Pietro Castellino 111, brevi talk, realizzati da ricercatori dell'istituto, guideranno i ragazzi alla scoperta delle applicazioni della matematica, con un linguaggio chiaro e accessibile a tutti.
