This model comprises a centroid motion caused by the resultant force and rotation around the centroid caused by the resultant moment.
This model was adopted for researching the influence of the mirror slope error and DNI and EATD tracking error on the focal spot characteristics (i.e., flux distribution, geometrical shape, centroid position, and intercept factor), and the tracking error transmission law of the EATD transferred to dish concentrator was studied (in Section 4).
The K-means clustering technique defines the K value to represent the group member of the cluster, and the centroid value on each cluster is set for initial value.

Specifically, the method reduces the effect that anatomical variations have on the positioning of deltoid and rotator cuff muscle origins relative to the centroid of the glenoid.
Furthermore, the amplitude of the component of the luminous centroid oscillation has been compared with the knock index evaluate through the in-cylinder pressure and the ion current based analyses.
The center of a cluster is termed as cluster centroid. Various clustering techniques have been developed [6] of which K-Means is used to cluster data in this study.
The next step is to take each point belonging to a given data set and associate it to the nearest centroid. When no point is pending, the first step is completed and an early clustering is done.
