Food design, or designer foods, or functional foods, or nutritionally modified foods, or genetically modified foods --are some of the myriad of terms that appear in the popular and scientific food and nutrition press. The similarities and differences in the meanings of these terms, and the implications for nutritional composition are not always clear. The goal of this paper will be to explore t...

In the paper, we consider the problem of computing visibility information on digital terrain models. Visibility problems on polyhedral terrains are classi ed according to the kind of visibility information computed into point visibility, line visibility and region visibility. A survey of the state-of-the-art of the algorithms for computing visibility is presented, according to the classi cation...

We develop in this paper some methods for studying the implicitization problem for a rational map φ : Pn 99K (P1)n+1 defining a hypersurface in (P1)n+1, based on computing the determinant of a graded strand of a Koszul complex. We show that the classical study of Macaulay Resultants and Koszul complexes coincides, in this case, with the approach of approximation complexes and we study and give ...
