The results revealed that T2 accuracy was reduced on disrupted trials, and disruption appeared to be worse when T2 appeared inside the attentional blink window.
The results show that the proposed inverse algorithm can predict the delamination parameters of location and size with good accuracy for numerically simulated frequency shift data but the prediction accuracy was reduced with experimental data.
The ships were fitted with anti-torpedo bulges, though these made maneuvering harder at low speeds and both rolled badly, and gunfire accuracy was reduced in rough seas.
However, these bulges made maneuvering harder at low speeds, she rolled badly, and her gunfire accuracy was reduced in rough seas.
This is a clean, accurate gauge that can be used down to about 10-6 torr; below this pressure its accuracy is reduced due to the soft X-rays produced by electrons striking the grid.
And of course accuracy is reduced by an enormous amount.
However, machining accuracy is reduced by lateral undercutting of the micro-dimples.
For rigid end-wall conditions, the accuracy is reduced near the end-walls to O N3/2), but recovers in the bulk.
The classification accuracy in Figure 18 is lower than in that in Figure 17 since there are more false negatives than false positives, and hence, the classification accuracy is reduced.
