ample linear system
1Linear system of divisors — A linear system of divisors algebraicizes the classic geometric notion of a family of curves, as in the Apollonian circles. In algebraic geometry, a linear system of divisors is an algebraic generalization of the geometric notion of a family of… …
2Ample line bundle — In algebraic geometry, a very ample line bundle is one with enough global sections to set up an embedding of its base variety or manifold M into projective space. An ample line bundle is one such that some positive power is very ample. Globally… …
3Compact linear Fresnel reflector — Fig.1: Example of a Traditional linear Fresnel reflector with one absorber. A compact linear Fresnel reflector (CLFR) – also referred to as a concentrating linear Fresnel reflector is a specific type of linear Fresnel reflector (LFR) technology.… …
4Mesoscale convective system — A shelf cloud such as this one can be a sign that a squall is imminent A mesoscale convective system (MCS) is a complex of thunderstorms that becomes organized on a scale larger than the individual thunderstorms but smaller than extratropical… …
5Music scheduling system — Music scheduling systems are employed to sequence music at radio stations. Although these systems were originally implemented by manual index card methods, since the late 1970s they have exploited the efficiency and speed of digital computers.… …
6Laning and Zierler system — The Laning and Zierler system was one of the first operating algebraic compilers, that is, a system capable of accepting mathematical formulae in algebraic notation and producing equivalent machine code. It was implemented in 1954 for the MIT… …
7Del Pezzo surface — In mathematics, a del Pezzo surface or Fano surface is a two dimensional Fano variety, in other words a non singular projective algebraic surface with ample anticanonical divisor class. They are in some sense the opposite of surfaces of general… …
8drawing — /draw ing/, n. 1. the act of a person or thing that draws. 2. a graphic representation by lines of an object or idea, as with a pencil; a delineation of form without reference to color. 3. a sketch, plan, or design, esp. one made with pen, pencil …
9Point spread function — The point spread function (PSF) describes the response of an imaging system to a point source or point object. A related but more general term for the PSF is a system s impulse response. The PSF in many contexts can be thought of as the extended… …
10Homogeneous coordinate ring — In algebraic geometry, the homogeneous coordinate ring R of an algebraic variety V given as a subvariety of projective space of a given dimension N is by definition the quotient ring R = K[X0, X1, X2, ..., XN]/I where I is the homogeneous ideal… …
