In all cases and in spite of all the differences pointed out before, which are very relevant, the parametric equation proposed fits very well.
The complexity found in these motifs is brought into contemporary design through a parametric equation that responds to programmatic requirements.

Nonlinear equation of the beam motion is reduced to linear parametric equation and solved in elliptic functions.
This variable profile is the essential property of the parametric equation curves, which suggests a formal definition of the parametric design; distant from external references, restrictions or regular alterations, which are the general interpretations of the concept parameter gathered from documents connected to constructive modelling.
The boundary of such channels in Cartesian coordinates {x, y, z} is described by a parametric equation [y.sub.w] = [y.sub.w][phi], [x.sub.w] = [[chi].sub.w]([phi]), where [phi] is a certain geometrical argument.
Aspherical shapes, such as paraboloids, can be programmed as a point table or with a parametric equation. Tool radius compensation features are used to adjust for wheel diameter.
Although the PLMK has given better predictions than the PLM, its drawback is the difficulty of generalizing using a parametric equation as in the PLMK-parm.
This parametric equation is the equation of the ideal bias-point locus that will satisfy [R.sub.I] = [R.sub.IO] across the temperature range.
"e(x,y) decreases as the distance from the longwall face increases"] we can suggest, hopefully better fitting reality, a parametric equation of e(x, y) with the number of parameters no greater than the number of sensors, estimate the parameters values and then estimate the [E.sup.P.sub.AE], AE energy estimated "given the model".
