Abstract

This paper aims to study large-scale processes that persist over time to describe their stability, and to monitor and diagnose negative changes. By utilizing fractal structure analysis of time series, the research investigates the applicability of the Hurst exponent in diagnosing the stability of various natural and man-made systems. The findings highlight the limitations of standard Gaussian statistics and the effectiveness of fractal analysis in revealing hidden patterns and long-term dependencies in complex systems.
