Students will acquire advanced knowledge in the field of experimental analysis of structures. They also learn to build acoustic models and create noise maps. The acquired skills is also a good knowledge of anti-noise and anti-vibration measures. These skills are taught both theoretically and practically.

Railway substructure, subdivision and construction of rail substructure and its construction layers, construction and shape of earth formation
Railway superstructure and modern railway structure design, interaction between railway vehicle and track, static track design, switches, crossings and turnouts.
Basic principles of numerical computations, basic elementary problems of numerical mathematics.
Physics, vibrations, proper vibrations, energy of a harmonics vibrations, damped vibrations, forced vibrations, addition of vibrations
Examination of the response of structures subjected to excitation, bases of the vibration theory, frequency domain analysis.

Modern methods of mathematical analysis, Fourier transform, fuzzy logic, neural networks.

Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations.
