This work explores a link between chaotic signals and the selection ofcontrolled variables for plantwide control system design. Some results areshown for the Tennessee Eastman plant, which is well-known for being achallenging ...

Time reversal of quantum dynamics can be achieved by a global change of the Hamiltonian sign (a hasty Loschmidt daemon), as in the Loschmidt Echo experiments in NMR, or by a local but persistent procedure (a stubborn daemon) ...

Solid state lasers are complex systems that sometimes display unstable aperiodic output. This behavior may be due to a deterministic low dimensional chaos. In this paper we show the results of a MATLAB based algorithm that ...

We report the experimental and theoretical verification that, in a diode-pumped Nd:YAG + Cr:YAG Q-switched laser, the instabilities in the pulse spacing ("jitter") are ruled by low-dimensional deterministic chaos. From our ...

Birdsong, a rich and complex behavior, is a stellar model to understand a variety of biological problems, from motor control to learning. It also enables us to study how behavior emerges when a nervous system, a biomechanical ...
