Salicornia procumbens and S. stricta are two tetraploid European salt marsh species of locally adjacent but ecologically differentiated distribution. Whereas S. procumbens grows in the lowest part of the salt marsh, it is replaced by S. stricta in the middle part (and diploid Salicornias in the upper part). Using AFLPs and a reciprocal transplantation experiment, we investigated whether the ...

Process Control of Ball Mill Based on MPC-DO
The grinding process of the ball mill is an essential operation in metallurgical concentration plants. Generally, the model of the process is established as a multivariable system characterized with strong coupling and time delay. In previous research, a two-input-two-output model was applied to describe the system, in which some key indicators of the process were ignored.
