Learning unit contents

Introduction to the basics of environmental modelling with exercises in R. 
Part Mathematical analysis:
The course will involve the following chapters:
1) Concepts and tools of mathematical analysis: revision of basic mathematics: function, limit and asymtotic behavior, derivative function (simple, composite and material, Taylor expansion), primitive and integration, basics of modelling (mass balance equation), (moving) averaging of continuous function, ..Remediation exercises will be organized. 
2) Dimensional analysis: dimensions, principle of dimensional homogeneity, characteristic length and time scales. Dimensional analysis, Pi theorem, systematic determination of dimensionless products, .. 
3) Interpolation: unidimensional and multi-dimensional interpolation, linear estimation, objective analysis, 
4) Analysis of time series: generalities, Fourier series and transform, filtering, 
5) Dynamical modelling with one equation: the Malthusian growth model, Verhulst logistic model, equilibrium and stability, linear perturbation analysis, solution of basic ordinary differential equations, 
6) Dynamic modelling with interactions: modelling of biochemical transformation, composed reactions, prey-predator, species competition, search for steady state solution, space phase analysis, and analyze the stability (linear perturbation, determination of the Jacobian matrix). R exercises will be organized. 
7) Modelling with partial differential equations: continuity equations, advection-diffusion equation in 3D and 1D , spectral window, ..
