For instance, a recent study on visual working memory [37] failed to find a modulation of the N2pc when two versus four targets were presented for a delayed match-to-sample judgment.
The questionnaires were conducted on the principle of convenience sampling and judgment sampling.
In the same way as the EFA, the data were gathered based on the principle of convenience sampling and judgment sampling.
As shown in Fig. 2a in the sample code, judgment dominate B4 is nested in judgment dominate B2, only consider B4 cannot correctly respond to the effects of variables assignment; in fact, the paths of {B2, B4} converge to B6.
The proposed strategy can overcome the sampling, logic judgment and information transmission processes of protection may be mistaken by the atrocious conditions, and form a strong intelligent secondary device integrated network.
It is also found from Figure 12b that the influence of the spark on sampling and judgment lasts more than 200 ns although the spark only lasts 9 ns.
Considering the fact that the sampling, logic judgment and information sharing processes of protection may fail in atrocious conditions, a distributed cooperative all-in-one device cluster based substation area joint defensive protection strategy is proposed.
If one protection device fails in harsh outside environment in all aspects of sampling, logic judgment, communication, the surviving device can form cooperative group and temporarily replaced the work of faulty device initiatively by overwriting vacant calculation module from mirroring storage.
From Figure 12, we can see that the base-band signal waveform in which period the spark appears is distorted seriously, which further influences the sampling and judgment, and results in bit errors, as shown by the dashed line in Figure 12c.
When selecting the interviewees, I relied on non-probability sampling methods, specifically purposive or judgment sampling and snowball sampling.
Although we believe our study villages to be fairly typical of rural Mid-east China, they were a judgment sample selected to give a broad range of villages.
