In mathematics, a curve (also called a curved line in older texts) is, generally speaking, an object similar to a line but that need not be straight. Thus, a line is a special case of curve null curvature.
Various disciplines within mathematics have given the term different meanings depending on the area of study, so the precise meaning depends on context. However, many of these meanings are special instances of the definition which follows. A curve is a topological space which is locally homeomorphic to a line. In everyday language, this means that a curve is a set of points which, near each of its points, looks like a line, up to a deformation. A simple example of a curve is the parabola, shown to the right. A large number of other curves have been studied in multiple mathematical fields.
A closed curve is a curve that forms a path whose starting point is also its ending point—that is, a path from any of its points to the same point.
In image editing, a curve is a remapping of image tonality, specified as a function from input level to output level, used as a way to emphasize colours or other elements in a picture.
Curves can usually be applied to all channels together in an image, or to each channel individually.
Applying a curve to all channels typically changes the brightness in part of the spectrum. The software user may for example make light parts of a picture lighter and dark parts darker to increase contrast.
Curve is a theatre in Leicester, England, based in the Cultural quarter in Leicester City Centre. Before being named Curve, it was referred to as Leicester Performing Arts Centre. It is adjacent to the Leicester Athena conference and banqueting centre.
Curve designed by architect Rafael Viñoly and engineered by Adams Kara Taylor is based in the centre of what the City Council calls the new "Cultural Quarter" on Rutland Street. It features two auditoria, one with 902 seats (referred to as the Theatre) while a 350 seat auditorium (referred to as the Studio) provides a smaller space with its own power flying system. The Theatre, Studio and their stages can also be opened up to create one large space with a capacity of 1,300. When the 32 tonne steel walls separating the stage and the foyer are lifted, the stage is visible from street level. The glass façade encloses an open plan foyer with views onto the café, bars, backstage area, and across the stage.
Offshore (1979) is a novel by Penelope Fitzgerald. It won the Booker Prize for that year. It recalls her time spent on boats on the Thames in Battersea. The novel explores the liminality of people who do not belong to the land or the sea, but are somewhere in between. The epigraph, "che mena il vento, e che batte la pioggia, e che s'incontran con si aspre lingue" ("whom the wind drives, or whom the rain beats, or those who clash with such bitter tongues") comes from Canto XI of Dante's Inferno.
"Offshore", when used relative to hydrocarbons, refers to an oil, natural gas or condensate field that is under the sea, or to activities or operations carried out in relation to such a field. There are various types of platform used in the development of offshore oil and gas fields, and subsea facilities.
For offshore energy that’s a big climb from essentially zero and time is short ...The InternationalRenewable EnergyAgency's 2019 white paper on the future of wind power also showed a steep growth curve for offshore wind over the next 30 years projecting global installed power at nearly 230 gigawatts by 2030 and 1,000 gigawatts by 2050....
"In Korea, as in Norway, the storage capacity will have to be found offshore," Rokke said ... "Clearly there is an ongoing technology race to make floating offshore wind power affordable and boost learning curves." ... Implementing CCS or offshore wind power isn't just talking about technology....
