Radar cross section — (RCS) is a measure of how detectable an object is with a radar. For example a stealth aircraft (which is designed to be undetectable) will have design features that give it a low RCS, as opposed to a passenger airliner that will have a high… … Wikipedia
cross section — 1. a section made by a plane cutting anything transversely, esp. at right angles to the longest axis. 2. a piece so cut off. 3. a photograph, diagram, or other pictorial representation of such a section. 4. the act of cutting anything across. 5.… … Universalium
radar cross section — The measure of reflectivity of the received radar signals by an aircraft, it is expressed as square meters (m2 ). It is dependent on the true size, range, aspect, geometric shape, materials, surface texture, and other properties of the target… … Aviation dictionary
Cross slope — is a geometric feature of pavement surfaces; the transversal slope [%] with respect to the horizon. It is a very important safety factor. One task is to make water run off the surface to a drainage system, as Cross Slope is the main contributor… … Wikipedia
Geometric and material buckling — In a nuclear reactor, criticality is achieved when the rate of neutron production is equal to the rate of neutron losses, including both neutron absorption and neutron leakage. Geometric buckling is a measure of neutron leakage, while material… … Wikipedia
Geometric albedo — The geometric albedo of an astronomical body is the ratio of its actual brightness at zero phase angle (i.e. as seen from the light source) to that of an idealized flat, fully reflecting, diffusively scattering (Lambertian) disk with the same… … Wikipedia
Section (fiber bundle) — In the mathematical field of topology, a section (or cross section) of a fiber bundle, pi; : E rarr; B , over a topological space, B , is a continuous map, f : B rarr; E , such that pi; ( f ( x ))= x for all x in B .A section is a certain… … Wikipedia
Cross product — This article is about the cross product of two vectors in three dimensional Euclidean space. For other uses, see Cross product (disambiguation). In mathematics, the cross product, vector product, or Gibbs vector product is a binary operation on… … Wikipedia
Geometric series — In mathematics, a geometric series is a series with a constant ratio between successive terms. For example, the series:frac{1}{2} ,+, frac{1}{4} ,+, frac{1}{8} ,+, frac{1}{16} ,+, cdotsis geometric, because each term is equal to half of the… … Wikipedia
Hollow structural section — A hollow structural section (HSS) is a type of metal profile with a hollow tubular cross section. In some countries they are referred to instead as a structural hollow section (SHS).Most HSS are of circular or rectangular section, although other… … Wikipedia
