In the latter case, the period of the oscillation is proportional to the relaxation time (time constant) of the system, hence the term relaxation oscillation. van der Pol (2) later gave the following defining properties of relaxation oscillations: 1. The period of oscillations is determined by some form of relaxation . The first relaxation oscillator circuit, the astable multivibrator, was invented by Henri Abraham and Eugene Bloch using vacuum tubes during World War 1.   Balthasar van der Pol first distinguished relaxation oscillations from harmonic oscillations, originated the term "relaxation oscillator", and derived the first mathematical model of a relaxation oscillator, the influential Van der.

A relaxation oscillation is a type of periodic behavior that occurs in physical, chemical and biological processes. To describe itmathematically, a system of coupled nonlinear differential equations is formulated. Such a system is studied with qualitative and quantitativemethods of mathematical analysis.
: Qualitative Analysis of the Periodically Forced Relaxation Oscillations (Memoirs of the American Mathematical Society) (): Levi, Mark: Books. In this book we analyze relaxation oscillations in models of lasers with nonlinear elements controlling light dynamics.
The models are based on rate equations taking into account periodic modulation of parameters, optoelectronic delayed feedback, mutual coupling between lasers, intermodal interaction and other factors.
There is a long history in ecology of using mathematical models to identify deterministic processes that may lead to dramatic population dynamic patterns like boom-and-bust outbreaks. Mathematical Ecology. In book: Methods and Models in Mathematical Biology, pp We give a geometric analysis of relaxation oscillations and canard cycles in singularly perturbed.
Relaxation oscillations in a kinetic model of catalytic hydrogen oxidation involving a chase on canards. Abstract. A detailed study of two- and three-variable mathematical models of a heterogeneous catalytic system is presented with special attention to weakly stable dynamics, a type of complex irregular behavior frequently encountered in.

A mathematical model may be used to help explain a system, to study the effects of different components, and to make predictions about behavior.
the model equations may never lead to elegant results, but it is much more robust against alterations. What objectives can modelling achieve? Mathematical modelling can be used for a number of diﬀerent reasons. How well any particular objective is achieved depends on both the state of knowledge about a system and how well the modelling is.mathematical modeling course, and as a reference volume for researchers and students.
