Scale Statistics
Scale or scales may refer to: Mathematics * Scale (descriptive set theory), an object defined on a set of points * Scale (ratio), the ratio of a linear dimension of a model to the corresponding dimension of the original * Scale factor, a number which scales, or multiplies, some quantity * Long and short scales, how powers of ten are named and grouped in large numbers * Scale parameter, a description of the spread or dispersion of a probability distribution * Feature scaling, a method used to normalize the range of independent variables or features of data * Scale (analytical tool) Measurements * Scale (map), the ratio of the distance on a map to the corresponding actual distance * Scale (geography) * Weighing scale, an instrument used to measure mass * Scale (ratio), the ratio of the linear dimension of the model to the same dimension of the original * Spatial scale, a classification of sizes * Scale ruler, a tool for measuring lengths and transferring measurements at a fixed rat ...

Scale (descriptive Set Theory)
In the mathematical discipline of descriptive set theory, a scale is a certain kind of object defined on a set (mathematics), set of point (mathematics), points in some Polish space (for example, a scale might be defined on a set of real numbers). Scales were originally isolated as a concept in the theory of uniformization (descriptive set theory), uniformization, but have found wide applicability in descriptive set theory, with applications such as establishing bounds on the possible lengths of wellorderings of a given complexity, and showing (under certain assumptions) that there are largest countable sets of certain complexities. Formal definition Given a pointset ''A'' contained in some product space :A\subseteq X=X_0\times X_1\times\ldots X_ where each ''Xk'' is either the Baire space (set theory), Baire space or a countably infinite discrete set, we say that a ''norm'' on ''A'' is a map from ''A'' into the ordinal numbers. Each norm has an associated prewellordering, where on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scale (film)
''Scale'' is a 2022 French animated short film directed by Joseph Pierce. The film debuted at the 2022 Critics Week at Cannes Film Festival and was produced by Melocoton Films (France), in co-production with Bridge Way Films (UK), Endorfilm (Czech Republic) and Ozù Productions (Belgium). ''Scale'' has received several nominations and awards, including a nomination for Best British Short Film at the 2022 British Independent Film Awards and winning the Golden Zagreb Award at the 2023 Zagreb World Festival of Animated Films. In August 2022, the film won the Oscar-qualifying award for Best Animation at HollyShorts Film Festival, and became eligible for the 96th Academy Awards. The film is also in the official selection for the 2024 César Awards. Background The film is an adaptation of the homonymous novella written by Will Self William Woodard Self (born 26 September 1961) is an English writer, journalist, political commentator and broadcaster. He has written 11 novels, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limescale
Limescale is a hard, chalky deposit, consisting mainly of calcium carbonate (CaCO3). It often builds up inside kettles, boilers, and pipework, especially that for hot water. It is also often found as a similar deposit on the inner surfaces of old pipes and other surfaces where hard water has flowed. Limescale also forms as travertine or tufa in hard water springs. The colour varies from off-white through a range of greys and pink or reddish browns, depending on the other minerals present. Iron compounds give the reddish-browns. In addition to being unsightly and hard to clean, limescale can seriously damage or impair the operation of various plumbing and heating components.Hermann Weingärtner, "Water" in ''Ullmann's Encyclopedia of Industrial Chemistry'', December 2006, Wiley–VCH, Weinheim. Descaling agents are commonly used to remove limescale. Prevention of fouling by scale build-up relies on the technologies of water softening or other water treatment. Limescale can als ...
