Con un programma fitto di appuntamenti, il CNR IAC è a Lucca dal 1° al 5 novembre con il progetto di divulgazione scientifica Comics&Science di CNR Edizioni, realizzato in collaborazione con Symmaceo Communications.

Incontri, laboratori, firmacopie per scoprire la scienza attraverso il fumetto. Di seguito tutto il programma.

Numerical Rock-Glacier Flow via the Pressure Method

Recent literature confirms the crucial influence of non-viscous deformations together with temperature impact on glacier and rock glacier flow numerical simulation. Along this line, supported by the successful test on a one-dimensional set-up developed by two of the author, we propose the numerical solution of a two-dimensional rock-glacier flow model based on an ice constitutive law of second grade differential type .

A Molecular Dynamics Study of the Evolving Melt Front under Gravity

During melting under gravity in the presence of a horizontal thermal gradient, buoyancy-driven convection in the liquid phase affects significantly the evolution of the liquid-solid interface. Due to the obvious engineering interest in understanding and controlling melting processes, fluid dynamicists and applied mathematicians have spent many efforts to model and simulate them numerically. Their endeavors concentrated in the twenty-five years period between the publication of the paper by Brent, Voller & Reid (1988) and that by Mansutti & Bucchignani (2011).

Prisma Noise Coefficients Estimation

The PRISMA (PRecursore IperSpettrale della Missione Applicativa) hyperspectral satellite, launched by the Italian Space Agency (ASI) is presently operational on a global scale. The mission includes the hyperspectral imager PRISMA working in the 400-2500 nm spectral range with 234 bands and a panchromatic (PAN) camera (400-750 nm). In the context of this work, we intend to determine the two noise components (photon and thermal noise) and assess SNR with an image based approach.
