A statistic to test whether the distributions of two observable variables are similar is proposed, where two distributions are defined as similar if they are the same except for a change in location and/or scale. The test statistic for similarity that is proposed extends the Kolmogorov–Smirnov...

To maximise the energy collected by a given photovoltaic system (PVS), it is important to track the position of the sun so that the PV panels are exposed to the maximum global radiation at any given time. Thus, it is useful to determine the direction of the maximum global radiation, which does...
