Algorithms for the sun sensor calibration, sun sensor and inclinometer alignment, sun image centroid
extraction, and heading determination are presented in detail.
This model comprises a dynamic model of the centroid
motion and a dynamic model of the rotation around the centroid
coordinates of the focal spot could be calculated by (13), where f(h, u) is the flux density of the grid hu on the plane receive.
where S is the total data point, [c.sub.i] is the centroid
cluster, and [x.sub.i] is the data point.
measurement method, the spinal curvature angle is defined as the angle between two tangents at centroid
points of two terminal vertebrae, which can be calculated as follows:
(c) The centroid
of the glenoid is located on the normal of the face plane that intersects the centre of the circle.
It has been determined as the CA of the first explosion through the analysis of the centroid
of luminosity dynamics.
where [mathematical expression not reproducible] are the centroid
coordinates of a certain suitability type in [t.sub.i] and [t.sub.i+1] year, [t.sub.i] and [t.sub.i+1] are the beginning and terminal years.
The 'average' operation is characterized by the centroid
, which is a P dimensional vector.
The main idea is to define k centroids
, one for each cluster.
where [m.sub.c] is mass, [a.sub.c] is vehicle body centroid
acceleration, L is vertical distance between suspension centroid
and vehicle centroid
, is pitching angle of vehicle body, [F.sub.1i] is acting force exerted by suspension on vehicle body, i = fl, i = fr, i = rl and i = rr represent left front wheel, right front wheel, left rear wheel and right rear wheel respectively.
The preoperative centroid
was 0.97 D x 91.97[degrees] [+ or -] 1.74, (p = 0.95), and the postoperative centroid
was 0.75 D x 98.59[degrees] [+ or -] 1.50, (p = 0.82).
