Obiettivi dell'insegnamento

I Part of the course: Numerical methods

The first part of the course will give the students the basic knowledge concerning the most important mathematical and numerical methods used to solve the equation of motion of fluids in porous media and to solve the elastodynamic problem.

II Part of the course: Statistical methods

The second part of the course aims at providing students with statistical tools for the analysis of data typically encountered in geo-science and environmental applications. The course is organized in theoretical classes and laboratories.

Course organization

The course is made of theoretical lectures followed by lab sessions. During the theoretical lectures methods and algorithms will be presented in the proper mathematical framework. During the lab sessions methods and algorithms will be instead illustrated and tested through applications to real data sets. The analyses performed during the lab sessions will be carried out by means the opensource software R (www.r-project.org). Along the course, students are expected to work on a data analysis team project.
