| The accelerometer perturbance was simulated with normal distribution. |
| With thousands of generators and hundreds of thousands of miles of lines, the network became so interconnected that even on a normal day a single perturbance can be detected thousands of miles away. |
| Perturbance that may have ecological consequences can include increases or decreases in abundance, changes in spatial or seasonal distribution, and other kinds of alternations that need to be assessed on a case by case basis. |
| Couple therapy carefully avoids blaming one of both partners for the perturbance. |
