And an improved quadric interpolation of normal vector is adopted in this new shading algorithm.

This paper presents an improved continuation power flow algorithm, whose characteristics are as following: PQ decoupled power flow algorithm is used; Lagrange quadric interpolation is used in the process of predictor and locally parameterized method is used in the corrector.

Discussion on data synchronization of electronic current transducer based on quadratic interpolation

Based on the method and precision of evaluating domain areas by analytic solution,the paper discusses the method of interpolating boundary points of curve domain with quadratic interpolation and the method of precisely evaluating curve domain areas with surveyed boundary points and interpolated boundary points by computers.

The emphasis of the study is Maximum Power Point Tracker based on quadratic interpolation.

enhanced dual-quadratic interpolation algorithm),which is suitable for non-uniform grid.

Based on the interpolation method,a model to represent the surface of a grid DEM based on biquadratic interpolation polynomial is obtained,and a propagation error formula by the polynomial is derived.

Kind of super-resolution method of CCD image based on wavelet and bicubic interpolation

This method,which combines bicubic interpolation and nonlinear extrapolation,utilizes bicubic interpolation in spatial domain to enhance the resolution of original low resolution image,and then utilizes nonlinear extrapolation in frequency domain to increase high frequency component of the image,finally,resolution enhancement of millimeter-wave radiometric image is actualized.

In order to improve its performance,this paper proposes bicubic convolution template algorithm:make the bicubic interpolation discrete and infer 16 templates,in which the original real operations are replaced by integer operations.
