In the paper we consider the issue related to the phenomenon of wheel-to-rail adhesion. This issue concerns self-excited vibrations in the area of wheel-rail contact, caused by unstable friction. Such friction is characterized by decreasing values of the friction coefficient with increasing slipping velocity. The paper includes mathematical formulation of the problem and presents the method for solving...
Opisano współczesne dokonania Wydziału Fizyki Politechniki Warszawskiej w dziedzinie holografii klasycznej, cyfrowej i komputerowej, w odniesieniu do pojęcia dwuetapowego obrazowania zaproponowanego po raz pierwszy przez prof. Mieczysława Wolfkego. W szczególności omówiono osiągnięcia w metrologii i wyświetlaniu obrazów z wykorzystaniem fazowych modulatorów ciekłokrystalicznych, jak i nowatorskich...
