Transport phenomenon in nuclear matter is addressed with the DYWAN model, which is based on the projection methods of statistical physics and on the mathematical theory of wavelets. Strongly compressed representations of the nuclear systems are obtained with a description of the wave functions and their antisymmetrization. Fluctuation-dissipation effects are investigated in nuclear collisions at intermediate energies and comparisons with experimental data and semi-classical models are presented. The study of different observables shows that these effects are correctly described in $\chem{Ar+Ag}$ and $\chem{Mo+Mo}$ reactions at different beam energies.
