Surface integral — In mathematics, a surface integral is a definite integral taken over a surface (which may be a curved set in space); it can be thought of as the double integral analog of the line integral. Given a surface, one may integrate over it scalar fields … Wikipedia
Parametrization — Parameterization (or parametrization; parameterisation in British English) is the process of defining or deciding the parameters usually of some model that are salient to the question being asked of that model. Context dependent meaning If, for… … Wikipedia
Parametrization (climate) — Parameterization in a weather or climate model within numerical weather prediction refers to the method of replacing processes that are too small scale or complex to be physically represented in the model by a simplified process. This can be… … Wikipedia
surface normal — noun A unit vector at any given point P of a surface M which is perpendicular to the tangent plane T(M) of M at P. For a surface with parametrization , it is given by :: :where the sign can be chosen at will … Wiktionary
Canadian Land Surface Scheme — The Canadian Land Surface Scheme (CLASS) is a land surface parametrization scheme for use in large scale climate models. It is a state of the art model, using physically based equations to simulate the energy and water balances of vegetation,… … Wikipedia
Parametric surface — A parametric surface is a surface in the Euclidean space R3 which is defined by a parametric equation with two parameters. Parametric representation is the most general way to specify a surface. Surfaces that occur in two of the main theorems of… … Wikipedia
Boy's surface — In geometry, Boy s surface is an immersion of the real projective plane in 3 dimensional space found by Werner Boy in 1901 (he discovered it on assignment from David Hilbert to prove that the projective plane could not be immersed in 3 space).… … Wikipedia
Roman surface — The Roman surface (so called because Jakob Steiner was in Rome when he thought of it) is a self intersecting mapping of the real projective plane into three dimensional space, with an unusually high degree of symmetry. The mapping is not an… … Wikipedia
Fréchet surface — In mathematics, a Fréchet surface is an equivalence class of parametrized surfaces in a metric space. In other words, a Fréchet surface is a way of thinking about surfaces independently of how they are written down (parametrized). The concept is… … Wikipedia
Boy's surface/Proofs — Property of R. Bryant s parametrizationIf z is replaced by the negative reciprocal of its complex conjugate, {1 over z^star}, then the functions g1 , g2 , and g3 of z are left unchanged.ProofLet g1 prime; be obtained from g1 by substituting z… … Wikipedia
Seashell surface — In mathematics, a seashell surface is a surface made by a circle which spirals up the z axis while decreasing its own radius and distance from the z axis. Not all seashell surfaces describe actual seashells found in nature.ParametrizationThe… … Wikipedia
