The mean drift velocity induced by longitudinal dilational waves in an elastic film is studied theoretically on the basis of a Lagrangian description of motion. The film is horizontal and situated at the interface between two viscous fluids. For time-damped dilational waves we let the film ~i! move freely with the mean fluid velocity at the interface, and ~ii! be kept fixed, i.e., having no mea...

The online drift velocity calibration method provides calibration parameters required at the very beginning of the offline reconstruction process in order to determine the z position of the particle tracks with a sufficient accuracy before the combined track finding [2]. It uses the TPC Laser System which generates 336 straight laser tracks, similar to ionizing particle tracks, at known positio...

The randomness of Brownian motion at thermodynamic equilibrium can be spontaneously broken by velocity-dependence of fluctuations, i.e., by dependence of values or probability distributions of fluctuating properties on Brownian-motional velocity. Such randomness-breaking can spontaneously obtain via interaction between Brownian-motional Doppler effects — which manifest the required velocity-dep...
