Multiscaling comparative analysis of time series and geophysical phenomena
Nicola Scafetta, Bruce J. West
Different methods are used to determine the scaling exponents associated with a time series describing a complex dynamical process, such as those observed in geophysical systems. M…
A Multifractal Dynamical Model of Human Gait
Bruce J. West, Nicola Scafetta
Summary: Walking is regulated through the motorcontrol system (MCS). The MCS consists of a network of neurons from the central nervous system (CNS) and the intraspinal nervous syst…
Influence of progressive central hypovolemia on multifractal dimension of cardiac interbeat intervals
Bruce J. West, Nicola Scafetta, William H. Cooke +1
We analyzed the heartbeat time series of 12 human subjects exposed to progressive central hypovolemia with lower body negative pressure. Two data processing techniques based on wav…
Statistical analysis of air and sea temperature anomalies
Nicola Scafetta, Tim Imholt, Paolo Grigolini +1
This paper presents a global air and sea temperature anomalies analysis based upon a combination of the wavelet multiresolution analysis and the scaling analysis methods of a time…
Complexity, multiresolution, non-stationarity and entropic scaling: Teen birth thermodynamics
Nicola Scafetta, Bruce J. West
This paper presents a statistical methodology for analyzing a complex phenomenon in which deterministic and scaling components are superimposed. Our approach is based on the wavele…
Non-extensive diffusion entropy analysis: non-stationarity in teen birth phenomena
N. Scafetta, P. Grigolini, P. Hamilton +1
A complex process is often a balance between non-stationary and stationary components. We show how the non-extensive Tsallis q-entropy indicator may be interpreted as a measure of…
