Two methods, based on nonlinear dynamics, are described for broad- and narrow-band communication systems. The first approach employs hyperchaotic discrete time series carrier sequences generated with mixed linear–nonlinear coupled differential equa

A new method is described for extracting mixed linear-nonlinear coupled differential equations from multivariate discrete time series data. It is assumed in the present work that the solution of the coupled ordinary differential equations can be repr

In this paper, two methods of the estimation of the kernels of a nonlinear model are considered. One is based on the orthogonalisation of the Gaussian input, the other one uses the moment hierarchy. Numerical examples are added to demonstrate the use

In this work a novel formalism to estimate the vector linear and leading non-linear impulse response functions from the experimental data observed from a multi-input system, allowing for correlation between the inputs, is presented. Time series stati

The dynamics of nonlinear systems can be characterized in terms of response functions. Mathematical representations of data that contain mixed stochastic-deterministic components are likely to have coefficients that are not well behaved. In these cir

Real buildings and their components experience dynamic thermal transmission. It is possible to represent thermal transmission as either a superposition of local constitutive convolution equations in a local region of the solid or as a directed graph

The present work studies single input nonlinear systems of arbitrary order which are driven by stochastic boundary conditions. Hierarchical moment equations generated by operating on the Volterra series convolution expansion are used to characterise

It has long been recognized that thermal response factors offer an accurate way to describe the characteristics and performance of a building or of its components. Although the existing techniques use time series methods they need to have carefully c
