Definition. the ratio of the area under sole cropping to the area under intercropping needed to give equal amounts of yield at the same management level. It is the sum of the fractions of the intercropped yields divided by the sole-crop yields. For a scenario where a total of crops are intercropped, the land equivalent ratio LER can be ...
The ratio of width to height of standard-definition television. In mathematics, a ratio (/ ˈ r eɪ ʃ (i) oʊ /) shows how many times one number contains another. For example, if there are eight oranges and six lemons in a bowl of fruit, then the ratio of oranges to lemons is eight to six (that is, 8:6, which is equivalent to the ratio 4:3).
When an original length is extended by a given amount, the final length is the sum of the original length and the length of the extension. [ 19 ] The sum a + b can be interpreted as a binary operation that combines a and b , in an algebraic sense, or it can be interpreted as the addition of b more units to a .
Aspect ratio. The aspect ratio of a geometric shape is the ratio of its sizes in different dimensions. For example, the aspect ratio of a rectangle is the ratio of its longer side to its shorter side—the ratio of width to height, [ 1][ 2] when the rectangle is oriented as a "landscape". The aspect ratio is most often expressed as two integer ...
A similarity (also called a similarity transformation or similitude) of a Euclidean space is a bijection f from the space onto itself that multiplies all distances by the same positive real number r, so that for any two points x and y we have. where d(x,y) is the Euclidean distance from x to y. [ 16]
Horizontal pitch (HP) is a unit of length defined by the Eurocard printed circuit board standard used to measure the horizontal width of rack mounted electronic equipment, similar to the rack unit (U) used to measure vertical heights of rack mounted equipment. One HP is 0.2 inches (1/5") or 5.08 millimetres wide.
Poisson's ratio of a material defines the ratio of transverse strain (x direction) to the axial strain (y direction)In materials science and solid mechanics, Poisson's ratio ν is a measure of the Poisson effect, the deformation (expansion or contraction) of a material in directions perpendicular to the specific direction of loading.
Wilson declined to answer why he wasn't 100% himself. His 47.30 split is almost three full seconds off the under-18 world record (44.59) that he set at the U.S. Olympic track and field trials.
