Spectral characteristics of two parameter fifth degree polynomial convolution kernel [PDF]
In this paper, the spectral characteristic of a polynomial two parameter convolutional fifth-order interpolation kernel is determined. The spectral characteristic is determined as follows. First, the kernel is decomposed into components.

Regular polynomial interpolation and approximation of global solutions of linear partial differential equations [PDF]
We consider regular polynomial interpolation algorithms on recursively defined sets of interpolation points which approximate global solutions of arbitrary well-posed systems of linear partial differential equations.

Equidistribution of the Fekete points on the sphere [PDF]
The Fekete points are the points that maximize a Vandermonde-type determinant that appears in the polynomial Lagrange interpolation formula. They are well suited points for interpolation formulas and numerical integration.

Polynomial Manifold Interpolation for Direction Finding in the Presence of Mutual Coupling
Direction-of-arrival (DOA) estimation in the presence of mutual coupling among the antennas is an important problem in direction finding systems. To address the mutual coupling issue, a polynomial manifold interpolation approach is proposed in this paper.
