On global geodesic mappings of quadrics of revolution
In this paper we study quadrics of revolution. Quadrics of revolution (except circular cylinder) admit nontrivial geodesic mappings and deformations in which they remain rotational. Surfaces (except circular cylinder and sphere) obt...

Projective equivalence of quadrics in Klingenberg projective spaces over a special local ring
This article is devoted to the projective equivalence of quadrics in Klingenberg projective spaces over a special type of local ring. Signature of quadrics is introduced by a suitable way (as a generalization of this one for qua...

A New Approach to Line-sphere and Line-Quadrics Intersection Detection and Computation
A new formulation of detection and computation of the intersection of line (ray) with a quadric surface is presented, which separates geometric properties of the line and quadrics that enables pre-computation......

The Surface as a Sum of Quadrics
A sum of two quadrics in suitable position can represent a surface which can be assumed as a geometric approximation of an air based surface. Several examples of such surfaces are presented....

Decomposition of Screw-motion Envelopes of Quadrics
Study and realization of the construction of the envelope helical and rotational surface are very important in the mechanical engineering practice. As the basic surface we take a quadrics in general position with respect to the axis for all ...

Quadric Resistive Sheet Profile for Wideband Antennas
A new type of a nonreflecting resistive dipole antenna with quadric continuous resistivity profile is presented in this paper. The antenna is mathematically described and compared with the antenna originally proposed by Wu and King. The veri...
