RCS, unique "signature" of an object created by the radar waves reflected from the object to the antenna (influenced by the shape of the object and the material it is made from)
A diagram or drawing that shows features transected by a given plane; specifically, a vertical section drawn at right angles to the longer axis of a geologic feature
A diagram or drawing that shows features transected by a given plane, usually a vertical plane so that the view shows features through the depth of the earth
A diagram or drawing that shows the sequence of rocks and sediment layers as they occur in a vertical plane; commonly drawn from the ground surface down to some selected depth, such as the bedrock surface
(physics) the probability that a particular interaction (as capture or ionization) will take place between particles; measured in barns a sample meant to be representative of a whole population a section created by a plane cutting a solid perpendicular to its longest axis
In nuclear physics, a measure of the probability that a given atomic nucleus will exhibit a specific reaction (absorption, scattering, or nuclear fission) in relation to a particular incident particle. Cross section is expressed in terms of area, and its value is chosen so that, if the bombarding particle hits a circular target of this size perpendicular to its path and centred at the nucleus, the given reaction occurs. If it misses the area, the reaction does not occur. The unit of cross section is the barn, which equals 10^-24 sq cm. Cross-section values for a given nucleus depend on the energy of the bombarding particle and the kind of reaction and are often different from the actual cross-sectional area of the nucleus
(1) A contraction of capture cross section (2) A diagram showing geological features transected by a vertical plane (3) A designation for a specific area (e g , borehole cross section)
A graph or plot of ground elevation across a stream valley or a portion of it, usually along a line perpendicular to the stream or direction of flow Cultural Resource Values: Floodplain values associated with the harvest of natural products (agricultural, aquacultural and forestry uses), as well as historical/archaeological, scientific and recreation/open space values Cumulative Impacts: The impacts on the environment that result from the incremental impact of an action when added to other past, present and reasonably foreseeable actions Cumulative impacts can result from individually minor but collectively significant actions taking place over a period of time
The side view of an object sliced along its vertical plane (For example, when you slice a two-layer cake, you can see the cross section of the cake--the bottom layer of cake, a layer of frosting, the top layer of cake, and the top layer of frosting )
A measure of the probability of a particular nuclear reaction occuring between a projectile and a target The probability is expressed as an area that the target presents The unit is the barn 1 barn = 10-28 m2
Cross section (sigma) is the device SEE response to ionizing radiation For an experimental test for a specific LET, sigma = #errors/(ion fluence) The units for cross section are cm2 per device or per bit

A cross-section of an object is what you would see if you could cut straight through the middle of it. a cross-section of an airplane The hall is square in cross-section
If you refer to a cross-section of particular things or people, you mean a group of them that you think is typical or representative of all of them. I was surprised at the cross-section of people there It is good that there is a wide cross-section of sport on television
Is a synonym for 'sample' and refers to the scientifically selected and representative group of households or individuals used in any given sample survey
A shape that determines the profile, or side view of certain 3D models Think of the cross-section as a cookie cutter or disk in a cookie press The shape of the cookie varies depending on the shape of the cutter or disk through which the dough is pressed For example, a line with a circular cross-section resembles a tube; a line with a star-shaped cross-section resembles a shooting star
(a) A diagram or drawing that shows features transected by a given plane; specif a vertical section drawn at right angles to the longer axis of a geologic or geomorphic feature, such as the mean direction of flow of a stream (b) An actual exposure or cut that shows transected geologic features
The shape of an individual filament when cut at right angles to its axis The shapes of manufactured fibers can be modified by changing the shape of the holes in the spinnerets used to extrude the polymer Typical cross-sections are round, trilobal, quadrilobobal, etc
