In the study of nonlinear phenomena in electronics, experiments are indispensable for the purpose of verifying the analytical findings and simulation results. This chapter begins with a discussion on the roles of experimental measurements and computer simulations in the study of nonlinear systems. A tutorial overview of the commonly used laboratory techniques for studying nonlinear phenomena in...

The growing need for a better understanding of nonlinear processes in plasma physics has in the last decades stimulated the development of new and more advanced data analysis techniques. Progress in this domain has greatly benefited from developments in fluid dynamics and dynamic system theory. This review lists some of the basic properties one may wish to infer from a data set and then present...

Spiking oscillators with pulse-train input(s) exhibit interesting synchronous phenomena and have been studied intensively in various fields including nonlinear electric circuits and neural networks [1]-[3]. The analysis of such synchronous phenomena is important as basic nonlinear problems in the various fields. Also, the analysis is fundamental for understanding dynamics of pulse-coupled neura...

Observations of the Sun and solar-type stars continue to reveal phenomena whose understanding is very likely to require a nonlinear framework. Here we shall concentrate on two such phenomena, namely the grand minima type behaviour observed in the Sun and solar-type stars and the recent dynamical variations of the differential rotation in the solar convection zone, deduced from the helioseismic ...

The dynamics in a nonlinear Schrödinger chain in a homogeneous electric field is studied. We show that discrete translational invariant integrability-breaking terms can freeze the Bloch nonlinear oscillations and introduce new faster frequencies in their dynamics. These phenomena are studied by direct numerical integration and through an adiabatic approximation. The adiabatic approximation allo...

in the present study an alternative model allows the extension of the debye-hückel theory (dht) considering time dependence explicitly. from the electro-quasistatic approach (eqs) done in earlier studies time dependent potentials are suitable to describe several phenomena especially conducting media as well as the behaviour of charged particles in arbitrary solutions acting as electrolytes.this...

The interest for neural networks stems from the fact that they appear as universal approximators for whatever kind of nonlinear dynamical system of arbitrary complexity. Because nonlinear systems, are studied mainly to model self-organization and emergence phenomena, there is the hope that neural networks can be used to investigate these phenomena in a simpler way, rather than resorting to nonl...

Curie symmetry principle, the causality relation between the symmetry of the causes and the resultant effect, has often been invoked to infer the composite deformation history of geological bodies in the Earth’s crust. This principle provides a powerful constraint for predicting an unavailable past physical condition; the effects at the macroscopic level must be the same or higher symmetry than...

Nonlinear vocal phenomena are a ubiquitous feature of human and non-human animal vocalizations. Although we understand how these complex acoustic intrusions are generated, it is not clear whether they function adaptively for the animals producing them. One explanation is that nonlinearities make calls more unpredictable, increasing behavioural responses and ultimately reducing the chances of ha...
