Scaling results for the average quantities (velocity, roughness, energy etc.) of the simplified version of the model are reviewed and it is shown that, for small oscillation amplitude of the moving wall, they can be described by scaling functions with the same characteristic exponents. New numerical results for the complete model are presented. The chaotic sea is also characterized by its Lyapunov exponents.700-707engChaosFermi ModelLyapunov ExponentScalingTrabalho apresentado em evento10.1590/S0103-97332006000500022S0103-97332006000500022WOS:000241151000022Acesso aberto2-s2.0-337482892972-s2.0-33748289297.pdf6130644232718610
