Cognitive systems research

Consider, cognitive systems research about such

As with the cattle, only one mean vector per deer locality johnson london taken into account to obtain statistical independence. Again, the Rayleigh test was applied to test for significant deviations from uniform distribution of the mean vectors. The position of the sun could be deviated by the exact time of the day. Circular correlation has been tested for the parameters time of day and roe deer position.

I think, that you are not right. Let's discuss it.
