The above calculations were carried out for a variety of loads in the range 10 -- 95% and our results indicate that
Load in the range 10 -- 20%: Average age waveforms are aperiodic but not self-similar Load in the range 30 -- 70%: Waveforms display self-similarity with Hurst parameter close to unity Load in the range 80 -- 99%: Waveforms contain a strong periodic component
