A hybrid Fermi-Ulam-bouncer model
Some dynamical and chaotic properties are studied for a classical particle bouncing between two rigid walls, of which one is fixed and the other moves in time, in the presence of an external field. The system is a hybrid, behaving not as a purely Fermi-Ulam model, nor as a bouncer, but as a combination of the two. We consider two different kinds of motion of the moving wall: (i) periodic; and (...
متن کاملTime resolved coherence-imaging spectrometer on WEGA stellarator
Imaging sensor technologies such as charge coupled devices and complementary metal-oxide-semiconductor have made remarkable progress in recent years. Fast imaging systems based on these new technologies are now being routinely employed for advanced fusion diagnostics. Since two-dimensional imaging considerably improves the investigation of threedimensional structural physics, we have installed ...
متن کاملScaling Properties of a Hybrid Fermi-Ulam-Bouncer Model
Some dynamical properties for a one-dimensional hybrid Fermi-Ulam-bouncer model are studied under the framework of scaling description. The model is described by using a two-dimensional nonlinear area preserving mapping. Our results show that the chaotic regime below the lowest energy invariant spanning curve is scaling invariant and the obtained critical exponents are used to find a universal ...
متن کاملDynamical properties of a dissipative hybrid Fermi-Ulam-bouncer model.
Some consequences of dissipation are studied for a classical particle suffering inelastic collisions in the hybrid Fermi-Ulam bouncer model. The dynamics of the model is described by a two-dimensional nonlinear area-contracting map. In the limit of weak and moderate dissipation we report the occurrence of crisis and in the limit of high dissipation the model presents doubling bifurcation cascad...
متن کاملThe Fermi-Pasta-Ulam problem(∗)
The Fermi-Pasta-Ulam model is a system of N+2 equal particles on a line with mutual interactions between adjacent particles, provided by a potential of the form V (r) = r/2 + αr/3 + βr/4; certain boundary conditions are also assigned, typically with the two extreme particles fixed. For α = β = 0 the system is a linear one, and by a familiar linear transformation it can be reduced to a system of...
