arc metric
1Arc length — Determining the length of an irregular arc segment is also called rectification of a curve. Historically, many methods were used for specific curves. The advent of infinitesimal calculus led to a general formula that provides closed form… …
2Metric system — This article is about the metric system in general. For information about specific versions of the system, such as the International System of Units or the cgs system of units, see #Variants. For a generally accessible and less technical… …
3arc furnace — a furnace in which heat is generated by an electric arc. * * * Type of electric furnace in which heat is generated by an arc between carbon electrodes above the surface of the material (commonly a metal) being heated. William Siemens first… …
4metric system — a decimal system of weights and measures, adopted first in France but now widespread, universally used in science, mandatory for use for all purposes in a large number of countries, and favored for use in most (as in the U.S.). The basic units… …
5Electric arc furnace — An electric arc furnace (EAF) is a furnace that heats charged material by means of an electric arc. Arc furnaces range in size from small units of approximately one ton capacity (used in foundries for producing cast iron products) up to about 400 …
6Convex metric space — An illustration of a convex metric space. In mathematics, convex metric spaces are, intuitively, metric spaces with the property any segment joining two points in that space has other points in it besides the endpoints. Formally, consider a… …
7Plasma arc waste disposal — Plasma Converter redirects here.Plasma arc gasification is a waste treatment technology that uses high electrical energy and high temperature created by an electrical arc gasifier. This arc breaks down waste primarily into elemental gas and solid …
8Minute of arc — This article is about geometry. For firearms terminology, see Minute of Angle. A minute of arc, arcminute, or minute of angle (MOA), is a unit of angular measurement equal to one sixtieth (1⁄60) of one degree. In turn, a second of arc or… …
9Glossary of Riemannian and metric geometry — This is a glossary of some terms used in Riemannian geometry and metric geometry mdash; it doesn t cover the terminology of differential topology. The following articles may also be useful. These either contain specialised vocabulary or provide… …
10Poincaré metric — In mathematics, the Poincaré metric, named after Henri Poincaré, is the metric tensor describing a two dimensional surface of constant negative curvature. It is the natural metric commonly used in a variety of calculations in hyperbolic geometry… …
