In the general case of a multicomponent material, an indicator function [[lambda].sub.C]([??]) takes the value 1 if the

radius vector is in component C and is equal to 0 in all other cases.

Afiter getting the midpoint vector PM, we need to calculate the

radius vector PR according to equation (4).

The estimation of the spatial position of the

radius vector shows the balance of system that represent the level of sustainable development.

with [epsilon] the mean obliquity of the ecliptic as defined in [6]; [r.sup.e.sub.S] is

radius vector of Sunmass center in Ecliptic Earth Centered Inertial Frame of J2000.0 defined as

In fact, for any method of compensation where a probe

radius vector is added to the coordinates of the probe center, the apparent point of contact cannot lie within the physical material and consequently compensation errors will always result in underestimating an internal diameter or overestimating an external diameter.

Searching algorithm is called with a

radius vector of components [rv.sub.i](Q) of value (1).

Note that in this paper the prototype shape is described by the thickness of the body measured orthogonally to the symmetry axis and not by the

radius vector function as in Streit (1997; 2000; 2003; 2005; 2006).

Each motivation factor will generate a partial motivation--that is a

radius vector of a point corresponding to the intensity of a motivation factor.

The efficient technique of the approximation of star contours of sources by a

radius vector which is set by the truncated trigonometric series has been used for cylindrical bodies with polygonal sections (Bulach & Mikheeva 1993)

(He makes the analogy with light, whose illuminating power decreases with distance.) First assuming that the orbits are eccentric circles (as did Ptolemy), he formulated his second law (chronologically the first) The

radius vector of the orbit sweeps out equal areas in equal times.

The position of the earth at any time is specified by the angle [alpha] of the

radius vector from sun to earth, which we will measure counterclockwise from the Spring equinox, with -180[degrees] < [alpha] [less than or equal to] 180[degrees] as in Figure 1.

Here Kepler set forth his first two laws of celestial motion: the planetary orbit is an ellipse with the sun as one of the loci; and the

radius vector drawn from the sun describes equal areas in equal times.
