We construct a phase diagram for the possible dynamics of one-dimensional, two-state, three-neighbor cellular automaton rules, using a new parameter (in conjunction with the previously known activity parameter). The new parameter 'estimates the average sensitivity of rule outcome to small changes in neighborhood configuration.
We propose a measure of complexity for symbolic sequences, which is based on conditional probabilities, and captures computational aspects of complexity without the explicit construction of minimal deterministic finite automata (DFA). Moreover, if the sequence is obtained from a dynamical system through a suitable encoding and its equations of motion are(More)
We show that applying a noise-reduction algorithm to a discretized time series increases its average error, compared to the original series. We find that adding external noise comparable to the discretization step before noise reduction limits the increase of the average error and improves the estimation of Lyapunov exponents.
KPD 1930+2752 is a short-period pulsating subdwarf B (sdB) star. It is also an ellipsoidal variable with a known binary period of 2.3 h. The companion is most likely a white dwarf and the total mass of the system is close to the Chandresekhar limit. In this paper, we report the results of Whole Earth Telescope (WET) photometric observations during 2003 and(More)
The chaos revolution is now more than 50 years old. Long anticipated by mathematicians, beginning with Henri Poincaré in the 1880s, the field finally emerged on the science stage in the early 1960s following the identification of chaotic behaviour in computer simulations of atmospheric and astronomical systems. Since then, many experimental observations of(More)
