Introduction: In this paper, a novel complexity measure is proposed to detect dynamical changes in nonlinear systems using ordinal pattern analysis of time series data taken from the system. Epilepsy is considered as a dynamical change in nonlinear and complex brain system. The ability of the proposed measure for characterizing the normal and epileptic EEG signals when the signal is short or is...

Contrary to conventional economic growth theory, which reduces a country's output one aggregate variable (GDP), product diversity is central development, as recent “economic complexity” research suggests. A reflects its of knowhow or “capabilities”. Researchers proposed the Economic Complexity Index (ECI) and country Fitness index estimate number capabilities from international export data; the...
