Subharmonic generation is a complex nonlinear phenomenon which can arise from nonlinear oscillations, bifurcation and chaos. It is well known that single-input-single-output Volterra series cannot currently be applied to model systems which exhibit s

The nonlinear autoregressive moving average model with eXogenous inputs (NARMAX) approach is used to analyse the dynamics of a gas turbine engine. The fuel flow-shaft speed relationship is analysed by identifying both time and frequency domain models

An approach based on the Nonlinear Autoregressive Moving Average Model With Exogenous Inputs (NARMAX) is used to analyze simultaneous measurements of the geomagnetic Dst index and VBs, the merging rate of the interplanetary magnetic field and the geo

The Response Spectrum Map (RSM) is introduced as a frequency domain equivalent to the Bifurcation Diagram. The RSM is a map of the energy distribution of a system in the frequency domain, where subharmonics, superharmonics and chaos generation can be

Time domain techniques are used to identify a dynamical model for the evolution of the Dst index under the influence of the solar wind. Frequency domain analysis of this model is used to study spectral properties of the Dst index dynamics. These prop

The representation of nonlinear dynamic wavelet models in the form of an equivalent global model which is valid over the operating range of the system is investigated. The results are used to analyse and interpret the nonlinear wavelet models using n

The spectral analysis of nonlinear wave forces is investigated based on the recently introduced Dynamic Morison equation. This equation accounts for nonlinearities associated with history or vortex shedding effects accurately, in contrast to the stan
