To compare the success rates for strabismus surgery designed to correct limitation of duction with surgery designed to correct deviation in patients with Graves' ophthalmopathy.
The PID approach would be analogous to a driver negotiating the road by continuously adjusting the input parameters, correcting deviation from the ideal line, proceeding along as the new corners or obstacles appear in front.
Education had two aspects: the teacher was to remove hindrances to the self-development or "self-activity" of the child, but he was also to correct deviations from what man's experience has taught is right and best.
In order to use the spindle probe measurement as a means of correcting deviations in machining, the magnitude of measurement errors needs to be quantified.
Procedures for school selection designed to mitigate selection biases, dynamic monitoring of the accumulating sample to correct deviations from recruitment targets, and a description of the recruitment procedures designed to foster a collaborative attitude between the researchers, the schools and the local communities, are provided.
The measurement group is the most affected group by high maturity implementation since they have to assist project managers, some members of the project team and the higher management with control information so that improvement actions can be planned and executed in time to correct deviations before concluding projects activities.
However, the longer it takes to react and correct deviations, the farther the state is from the target path, and the more difficult it is to restore the system to the lasting path.
The threshold must be high enough to avoid correcting deviations due to random measurement noise while remaining sensitive to systematic sources of error.
This model was based on influential work by Todorov and Jordan (2002, 2004), who showed the selective use of sensory feedback to correct deviations that interfere with task goals could account for several unexplained effects in motor control, such as the variability of task-irrelevant movement qualities.
As noted in the opening of this section, the quality of the overall system performance will depend jointly on its ability to respond effectively to both the observer demands associated with detecting the signals in the noise and the control demands associated with the speed/accuracy constraints for correcting deviations from intentions (i.e. errors).
