Title: On-off intermittency in forced and coupled systems

On-off intermittency is a phase-space mechanism that generates
bursting behavior. Here I shall discuss some of the basic properties
of this type of dynamical behavior, and will address the
characteristics of time series generated by on-off systems. I shall
also show how this mechanims can be distinguished from other forms of
intermittency, and how it can be confused with simpler forms of
intermittency such as a nonlinearly-filtered linear autoregressive
signal.
