A thicker collimator would result in better rejection of radiation originating from regions outside the FOV, and thus a better spatial resolution, but also a lower overall sensitivity.
More specifically, a larger value of leads to better rejection capabilities of the side lobe signals and the larger detection loss for matched signals.
In addition, the modified negatively charged membrane with a strongly acidic (sulfonic acid) functional group has better rejection of humic acid and less membrane fouling than that with a weakly acidic (carboxylic acid) functional group.
A moderate annealing is also used to manipulate the pore size for a better solute rejection.
To obtain a better disturbance rejection property, we employ finite-time control techniques.
With this estimate, it becomes possible to close an inner loop around the coal mill itself, thus giving a better disturbance rejection capability.
The simulation results demonstrate that the proposed method has a better disturbance rejection property than those of the MPC and PI methods in controlling ball mill grinding circuits.
In this paper, a systematic procedure is proposed for the generalized design of decoupling multivariable controller, which may result in a complete decoupling, partial decoupling or no decoupling, to achieve a better disturbance rejection response.
For the same robustness, a better disturbance rejection response is obtained by the proposed controller than that of the PID, by adjusting only two parameters with a clear meaning.
