coordinate axes

[kō′ȯrd·ən·ət ′ak‚sēz]
(mathematics)
One of a set of lines or curves used to define a coordinate system; the value of one of the coordinates uniquely determines the location of a point on the axis, while the values of the other coordinates vanish on the axis.

In Equation (9), [u'.sub.0_h] and [u'.sub.0_V] are the amplitude of the horizontal polarization component and the vertical polarization component of the incident wave on dV, respectively; [f.sub.12], [f.sub.21], and [f.sub.22] are the elements of the scattering amplitude function matrix for the raindrop with the diameter D, which are the functions of scattering angle [THETA] (cos = [THETA] = [[??].sub.0] X [??]), and are related to the scattering functions [S.sub.1], [S.sub.2], [S.sub.3] and [S.sub.4] used by Van de Hulst and in Mie solution for a sphere [48, 50]; [??] is the unit vector of a scattering direction in the coordinate axes xyz.
Almost all companies in this area carried out their own triangulation measurements and had a local coordinate system in which the coordinate axes were parallel to the St.
(2) Tests of novel relations addressed curve fitting; that is, participants were trained with exemplars in the form of solid-line functions, but because graphical data are often represented as a series of data points rather than solid lines (Sullivan, 2002), novel test stimuli were composed of more challenging scattered dots on the coordinate axes. Some functions were composed of tightly compressed dots resembling the more traditional solid line, while other functions were composed of widely dispersed scattered dots, making their particular patterns much more difficult to identify as a mathematical function.
Hence, the action of the Hyperbolic Law covers also an area of negative values of coordinate axes covering 155.
The profiles boundaries approximately follow the chosen coordinate axes in the XY and YZ planes and the profile elongation along the transverse axis Y is preponderant, which is somewhat surprising in the XY plane as X is the pressing direction.
Upon a suitable rotation of coordinate axes, analysis of closed-discharge single-screw extrusion is simplified.
But the weightless, hovering object shifted attention from the grid's rigid coordinate axes to its open interstices, its slack spots.
A positioning table in motion has six degrees of freedom along or about the three perpendicular coordinate axes. To produce the highest accuracy in any given axis of linear motion, the error in the remaining five degrees of freedom needs to be controlled and minimized.
The structure may be rotated about any of the 3 coordinate axes with the mouse, thus facilitating viewing the molecule from different angles.
{c = 1,2,3,4}, where each value of c identifies a different corner of the rectangle A as the origin of the coordinate axes and where ([x.sub.c,k], [y.sub.c,k]) denotes the location of the [k.sup.th] sampling location relative to the origin at corner c.
It is designed to record the position of a spherical probe as it is moved along three coordinate axes as shown in Figure 2.
Then combining 2D magnetic field vectors of all 3 coordinate axes with each other formed a 3D magnetic field, which rotated around an arbitrary axis passing through a fixed spatial point.
