Variations in the performance of the mentioned technique are then evaluated both in terms of changes in the estimated difference between the responses of the damaged and undamaged systems and in terms of deviations of the identified optimal input signal from its nominal estimation.
An important consequence of these experiments is that training in the rotated environment may not be helpful for improving task performance, especially in undamaged motor systems, since the rotated environment leads to modification of the environment adaptation module but not the task generation module.
After a fire, buds under the woody outer layers of this organ quickly grow, using the undamaged original root system; a new crown develops within a few months.
It might be speculated that the long-term neuroplastic changes occurring in the affected hemisphere following stroke might be of maladaptive nature, not facilitating the process of functional recovery, or that priming the undamaged pharyngeal motor system in the chronic phase may assist the affected hemisphere to participate in the process of recovery.
The difference between measurable outputs of the undamaged and damaged systems then simply becomes a state in this augmented system which may be then maximized by maximizing a related and easily developed cost function.
In terms of damage accumulation, the proposed SW system is nearly undamaged compared to the conventional wall system, which was severely damaged at the wall-base region.
The dynamic characteristics of the system in its undamaged and damaged configurations are identified upon ambient-like accelerations from a low dense sensor network.
It is shown, that thanks to the influence of elastic non-linearity of the crack, new non-linear properties which are impossible in the initial undamaged structure, appear in the system (self-excitation of subharmonic regimes, appearance of even-numbered harmonic components in frequency spectrum of 3/1 order superharmonic regime).
If the reference data are only characteristic of a limited range of the environmental parameters, measurements from the system in an undamaged condition but from a different environmental state, may cause the diagnostic to register novelty and thus falsely infer damage.
Hydraulic system two was undamaged.
