A.I.Neishtadt . Probability phenomena in perturbed dynamical systems . ... If in a deterministic dynamical system a small variation of initial conditions produces a significant change of motion, then the behavior of such a system is practically non-distinguishable from a random one. ... Such quasi-random behavior exists also in systems which differ by an arbitrary small perturbation from systems with a very simple (periodic or quasi-periodic) dynamics. ...

... Here is some programming information for common ports that can be directly used for general-purpose TTL (or CMOS) logic I/O. If you want to use these or other common ports for their intended purpose (e.g., to control a normal printer or modem), you should most likely use existing drivers (which are usually included in the kernel) instead of programming the ports directly as this HOWTO describes. ... The game port has a quad one-shot multivibrator (a 558 chip) connected to the four inputs. ...

... Email: chaos@mail.cplire.ru . ... We investigate phenomena on the edge of spatially homogeneous chaotic mode and spatiotemporal chaos in a lattice of chaotic 1-D maps with local connections. We show that spatially homogeneous chaotic mode cannot exist in a lattice with local connections if the Lyapunov exponent of the isolated chaotic map is greater than some critical positive value. We propose a few schemes that make spatial synchronization possible in large lattices. ...
