Nonlinear systems come in all shapes and sizes. Linear dynamics is a useful abstraction, but if you look long enough at any real system you consider linear, you will discover nonlinearities. It ...

Linear Elamite, a writing system used in what is now Iran, may reveal the secrets of a little-known kingdom bordering Sumer ...

But linear systems can do more than just count chickens and pigs. They crop up in many practical settings, where building a sturdier bridge or a stealthier aircraft can involve solving systems with ...

In this paper we estimate a complete system of demand equations making full use of the restrictions implied by economic theory. Our theoretical model is based on the Klein-Rubin linear expenditure ...

Concepts of feedback; open loop and closed loop systems. Feedback in electrical and mechanical systems. Mathematical models of systems and linear approximations. Transfer functions of linear systems, ...

Several approaches are explored for testing the hypothesis that no switch has occurred in the true values of the parameters of a linear regression system. The distribution of the relevant likelihood ...
