A new determinantal representation for the implicit equation of offsets to conics and quadrics is derived. It is simple, free of extraneous components and provides a very compact expanded form, these representations being very useful when dealing wit

A new algebraic framework is introduced for computing the topology of the offset C δ at distance δ to a rational plane curve C defined by a parameterization ( x ( t ) , y ( t ) ) . The focus is on computing the topology of C δ by analyzing the ima

In this paper, a general theoretical study, from the perspective of the algebraic geometry, of the untrimmed bisector of two real algebraic plane curves is presented. The curves are considered in C 2 , and the real bisector is obtained by restriction

The availability of the implicit equation of a plane curve or of a 3D surface can be very useful in order to solve many geometric problems involving the considered curve or surface: for example, when dealing with the point position problem or answeri

BACKGROUND: Although recent diagnostic criteria for Alzheimer's disease propose the use of biomarkers, validation of these biomarkers by diagnostic test accuracy studies is a necessary first step, followed by the synthesis of the evidence from these

The ergot alkaloid derivative nicergoline became clinically available about 35 years ago in the 1970s. Nicergoline has a broad spectrum of action: (i) as an alpha(1)-adrenoceptor antagonist, it induces vasodilation and increases arterial blood flow;

In this paper a new algorithm for computing the intersection of two rational ruled surfaces, given in parametric/parametric or implicit/parametric form, is presented. This problem can be considered as a quantifier elimination problem over the reals w
