In mathematics, the (right) Ziegler spectrum of a ring R is a topological space whose points are (isomorphism classes of) indecomposable pure-injective right R-modules. Its closed subsets correspond to theories of modules closed under arbitrary products and direct summands. Ziegler spectra are named after Martin Ziegler, who first defined and studied them in 1984. (Wikipedia).
Designing a PID Controller Using the Ziegler-Nichols Method
In this video we discuss how to use the Ziegler-Nichols method to choose PID controller gains. In addition to discussing the method and providing a Matlab implementation of the procedure, we demonstrate the effectiveness of the resulting controller on a real system. Topics and time stamp

15. Metals and Catalysis in Alkene Oxidation, Hydrogenation, Metathesis, and Polymerization
Freshman Organic Chemistry II (CHEM 125B) Alkenes may be oxidized to diols by permanganate or by OsO4 catalysis. Metal catalysts provide orbitals that allow simultaneous formation of two bonds from metal to alkene or H2. Coupling such oxidative additions to reductive eliminations, provi

A PID Tuning Guide | Understanding PID Control, Part 4
It can be difficult to navigate all the resources that promise to explain the secrets of PID tuning. Some proclaim that PID tuning is an art that requires finesse and experience, while others are adamant that tuning requires a few rigid rules. Why is there such a vast difference? It is b
