Intersecting surfaces of special types

Proceedings Shape Modeling International '99. International Conference on Shape Modeling and Applications, 1999
The paper reviews new approaches to computing the intersection curve of two surfaces of special types. We consider algorithms for intersecting a torus with a natural quadric or another torus. After that, we review a topological technique that computes the intersection curve of a sphere and a surface of revolution.

Metallic surfaces with special wettability

Nanoscale, 2011
Metals are important and irreplaceable engineered materials in our society. Nature is a school for scientists and engineers, which has long served as a source of inspiration for humans. Inspired by nature, a variety of metallic surfaces with special wettability have been fabricated in recent years through the combination of surface micro- and ...

Special curves and ruled surfaces

Hokkaido University Preprint Series in Mathematics, 2001
Cylindrical helices and Bertrand curves are studied from a new point of view: they are considered as curves on a ruled surface. It is shown that a ruled surface is the rectifying developable of a curve \(\gamma\) if and only if \(\gamma\) is the geodesic of the ruled surface which is transversal to rulings and whose Gaussian curvature vanishes along \(\

Regional specialization of the surface of a parasitic nematode

Parasite Immunology, 1986
Summary A monoclonal antibody (NIM‐M7) has been prepared which reacts with a major surface antigen of adult males and females of Trichinella spiralis. This specificity is only demonstrable when the antigen is liberated by detergent solubilization of surface‐labelled worms. When reacted with living adults, on the other hand, NIM‐M7 reacts well with only

Special Families of Surfaces

2021
The chapter is devoted to the study of special families of surfaces which are of common use in architecture such as ruled surfaces and some of their subfamilies. The technique followed for achieving a parametrization is also described in detail. Quadrics, minimal and developable surfaces are also considered.

Special divisors on curves on aK3 surface

Inventiones Mathematicae, 1987
Let \(C\) be a smooth irreducible complex projective curve of genus \(g\ge 2\). The Clifford index of a line bundle \(A\) on \(C\) is the integer \(\mathrm{Cliff}(A)=\deg (A)-2\cdot (h^0(A)-1)\). The Clifford index of \(C\) itself is defined as \(\mathrm{Cliff}(C)=\min \{\mathrm{Cliff}(A)\mid h^0(A)\ge 2, h^1(A)\ge 2\}\). Clifford's theorem says that \(

Special Slant Surfaces and a Basic Inequality

Results in Mathematics, 1998
A slant immersion is an isometric immersion of a Riemannian manifold into an almost Hermitian manifold with constant Wirtinger (or Kähler) angle \(\theta\). It is called proper if it is neither holomorphic nor totally real. Let \(\widetilde M^2(4\varepsilon)\) be a complex space form with constant holomorphic sectional curvature \(4\varepsilon\).
