A Generalised Approach for the Prediction of Laser Cutting Parameters [PDF]

open access: yes, 1989
A design of a tasking and control environment for laser based manufacturing systems is proposed. This uses an empirical approach based on recording previous manufacturing experience in a database, in order that this can be used in planning and control of

Optimal fluctuations and the control of chaos. [PDF]

open access: yes, 2002
The energy-optimal migration of a chaotic oscillator from one attractor to another coexisting attractor is investigated via an analogy between the Hamiltonian theory of fluctuations and Hamiltonian formulation of the control problem.

Influence of liquid film thickness on bearing characteristics of magnetic-liquid suspension guide-way

open access: yesThe Journal of Engineering, 2018
The magnetic-liquid suspension guide-way (MLSG) adopts the double support form of permanent magnetic suspension and hydrostatic pressure. It can greatly enhance the bearing capacity and rigidity of the guide-way system.
