First-order systems are those which can be described by first-order differential equations. A common example is the RC circuit. You will need Adobe Acrobat Reader to ...

The application of collocation methods for the numerical solution of singularly perturbed ordinary differential equations is investigated. Collocation at Gauss, Radau and Lobatto points is considered, ...

This is a preview. Log in through your library . Abstract A quasilinear elliptic equation of second order can be split into a first order system in various ways. We present and analyze a stabilized ...

Optical instruments are how we see the world, from corrective eyewear to medical endoscopes to cell phone cameras to orbiting telescopes. Prior knowledge needed: Undergraduate level physics, ...

In the previous article, I showed how to compensate simple first-order systems. As a quick recap, a Proportional-Integral (PI) controller is all that is needed for compensating first-order systems ...
