On Fermat power GCD matrices defined on special sets of positive integers
Applied Mathematical Sciences, 2019In this article, we define the n×n Fermat Power GCD matrices defined on non factor-closed and non gcd-closed sets. A complete characterization of their factorizations, determinants, reciprocals, and inverses are given. Mathematics Subject Classification:

A Fast Algorithm for Spherical Basis Approximation
, 2006Radial basis functions appear in a wide field of applications in numerical mathematics and computer science. We present a fast algorithm for scattered data interpolation and approximation on the sphere with spherical radial basis functions of different ...

Applications of strong Grobner bases over Euclidean domains
, 2013Strong Gröbner bases over Euclidean domains and even more general rings were first defined in the 1980s. Since that time, efficient ways to compute them, and a variety of applications, have appeared.

A matrix analytic approach to conjugate diameters of an ellipse
, 2013Herein, problems pertaining to the conjugate diameters of a nondegenerate ellipse are studied within a matrix analytic framework. Pride of place is reserved for the construction of the matrix associated with the positive definite quadratic form defining ...

Robust Frame Based X-Ray CT Reconstruction
, 2016As X-ray computed tomography (CT) is widely used in diagnosis and radiotherapy, it is important to reduce the radiation dose as low as reasonably achievable. For this purpose, one may use the TV based methods or wavelet frame based methods to reconstruct
