[mathematical expression not reproducible] is vector that defines the gravitational acceleration at the reference
coordinate system; [mathematical expression not reproducible] is vector of a mass center position of the body i, defined in the reference
coordinate system.
Especially, when the number of iterations is considered, one can note essential influence of the
coordinate system on results of PSSE.
The coordinate of spindle center hole in visual
coordinate system is given by
In Figure 2, u-v is the rotor synchronous rotating
coordinate system; M is the centroid of rotor; G([[alpha].sub.m], [[beta].sub.m]) is the axis of rotor; [xi] is the eccentric distance of rotor mass, [theta] is the initial mass eccentricity angle in the u-v
coordinate system.
In practical applications, (4) and (5) often need to be solved in Cartesian coordinates, thus, they are transformed from a curvilinear
coordinate system by transformation matrix, which can be written as follows:
The transformation matrix of the missile body
coordinate system to the outer gimbal
coordinate system can be written as follows:
(iii) Optical flow sensor
coordinate system ([S.sub.OF] - [o.sub.OF] [x.sub.OF][y.sub.OF][z.sub.OF]): a
coordinate system fixed to a optical flow sensor.
(1), they can always be expressed in terms of the gimbal
coordinate system as
In the parallel polarization z(yy)[bar.z] and cross polarization z(yx)[bar.z] of backscattering geometry, the unit polarization vectors in specimen
coordinate system can be expressed as
Recently, we proposed a reference
coordinate system that was established on the lateral skull surface based on several conspicuous osseous landmarks.
