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 ...

Linear actuators and oscillating systems constitute a vibrant area of research that bridges concepts in electromagnetism, mechanics and control engineering.

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 ...

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, ...

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 ...

Two teams found different ways for quantum computers to process nonlinear systems by first disguising them as linear ones.
