Illustrating ellipse and sinusoid curves,the coordinate conversion and programming in the process of using macro command were stated.

In this paper we discuss the representation of integral circle,cycloid and sinusoid on a period by uniform C-B-splines of degree 3.

A digital frequency synthesizer without ROM look up table is presented,a piecewise linear interpolation scheme is used to approximate a sinusoid function.

Considering the sine curve as the primary equation of hydraulic geometry andsolving togather with continunity eqution of water flowing and other relative equations, depth, breadth and slope of sinuous channel have been deduced.

A real-time fast interpolation algorithm for hdical and sine curves based on the principleof time-slicing method is proposed.

This paper discusses a method of synthesizing free curve and sine curve.

With the UHARD subroutine,the hyperbolic sine constitutive relationship was implemented into the ABAQUS code,which established the foundation for the metal deformation at high temperature.

A Fast Approach to Detect a Kind of Sinusoidal Curves Using Hough Transform;

In present work, it is exceedingly difficult to control the scale and precision of some special surfaces such as sinusoidal curve, ellipse, parabola, etc.
