Characteristic curves are derived from the training views, and primitives of the curves are detected.

The turns of a serpentine band comprise connected turns and unconnected turns, each connected turn having a connector strut extending therefrom.

realignment by string line and versine offset

Provided is a graphic information processing device capable of forming curves suited for designs (such as beautiful curves or aesthetic curves) easily.

The invention provides a skate for a curved stairlift, the skate having the ability to traverse transition bends, inside/outside bends, and helical bends in a stairlift rail.

The introducer device may include a needle with multiple curves, some of the curves having multiple radii.

The downward-sloping curves are indifference curves called isototal benefits curves.

As features related to curves, there are the magnitude of the curvatures and the direction of the curves, for example.

This is repeated for each of the curves of the group of pitch and rotational speed curves.

Radii of curvature for the inner curves (70), (72) are greater than radii of curvature for the outer curves (64), (66).

Graphical methods for fitting curves can be used.

electrochemical methods of recording polarisation curves

Variations adapted for scoliotic curves are provided.

Such a Ct value is usable for sigmoidal curves and parabolic curves, and can provide linear calibration curves to achieve accuracy in determining initial concentrations of a sample.
