Symbolic dynamics of one-dimensional maps: Entropies, finite precision, and noise

International Journal of Theoretical Physics, 1982
In the study of nonlinear physical systems, one encounters apparently random or chaotic behavior, although the systems may be completely deterministic. Applying techniques from symbolic dynamics to maps of the interval, we compute two measures of chaotic behavior commonly employed in dynamical systems theory: the topological and metric entropies.

Influence of dynamical noise on time series generated by nonlinear maps

Physica D: Nonlinear Phenomena, 2008
Consider the dynamical noise called ``pseudonoise'' corrupting a time series generated by a discrete iterated function system (map). Especially, the discrete maps \[ x_{n+1} = f(x_n) \] modified by the two types of maps \[ y_{n+1} = f(y_n) + \eta_n \] or \[ z_{n+1} = f(z_n+\eta_n) \] with noise terms \(\eta_n\) are under consideration.

Signal‐to‐noise analysis of cerebral blood volume maps from dynamic NMR imaging studies

Journal of Magnetic Resonance Imaging, 1997
AbstractThe use of cerebral blood volume (CBV) maps generated from dynamic MRI studies tracking the bolus passage of paramagnetic contrast agents strongly depends on the signal‐to‐noise ratio (SNR) of the maps. The authors present a semianalytic model for the noise in CBV maps and introduce analytic and Monte Carlo techniques for determining the effect
