Pattern selection as a nonlinear eigenvalue problem,cal simulations of propagating vortex structures occuring in Taylor-Couette and Rayleigh-Bénard systems subject to an externally imposed through-flow. Unlike the stationary patterns in systems without through-flow the spatiotemporal structures of propagating vortices are independent of parameter his

Conditional probability distributions of a turbulent cascade,ncrements . ., . . of different lenght scales . ., . .. We present experimental evidence that the conditional probability distribution .(. ., . .|. ., . .) obeys a Chapman-Kolmogorov equation. We evaluate the Kramers-Moyal coefficients and show that the third and fourth order coefficients vanish. Th

Why air bubbles in water glow so easily,. Air is found to be one of the most friendly gases towards this phenomenon. Recently, Lohse et al. (1996) have suggested a chemical mechanism to account for the strong dependence on the gas mixture: the dissociation of nitrogen at high temperatures and its subsequent chemical reactions to highly wa

Competition of growth patterns in directed growth,ume that the growing phase consists of several sub-phases or species or even of several dynamically defined growth patterns, and that the growth takes place by the propagation of an extended front which separates the growing from the shrinking phase. A coarsening process then takes place during grow

Experiments on excitation waves,st suitable chemical laboratory system for the study of wave propagation in excitable medium, the efficient control of wave dynamics by electrical fields and by light illumination is illustrated. In particular, the effects of a feedback control are shown. Further new experiments in this system are c
