In numerical analysis, "'Riemann problems "'appear in a natural way in finite volume methods for the solution of conservation law equations due to the discreteness of the grid.

The terminology introduced above is coherent with this, as a theorem due to Borel and Harish-Chandra states that an arithmetic lattice in a semisimple Lie group is of finite covolume ( the discreteness is obvious ).
33.
A convolution method of regularization reduces the discreteness of the bootstrap distribution by adding a small amount of " N " ( 0, " ? " 2 ) random noise to each bootstrap sample.
34.
The discreteness in this case is easy to see from the group action on the tree : a subgroup of \ mathrm { Aut } ( T ) is discrete if and only if all vertex stabilisers are finite groups.
35.
The strength of a label can be determined by three factors : analysis of affective ( or emotional ) strength, permeability ( the ability to break through ) of boundaries, and a judgment ( measurement of rigidity ) of discreteness.
36.
So, for example, when the symmetry group is a Lie group, then the charge operators correspond to the simple roots of the root system of the Lie algebra; the discreteness of the root system accounting for the quantization of the charge.
37.
Due to the discreteness of electrical charge, current through a tunnel junction is a series of events in which exactly one electron passes ( " tunnels " ) through the tunnel barrier ( we neglect cotunneling, in which two electrons tunnel simultaneously ).
38.
The discreteness of energy, as understood in the early 20th century, was exactly a consequence of the fact that physical systems were made of atoms that could only transfer energy in discrete amounts . talk ) 19 : 09, 9 January 2008 ( UTC)

Frankly, I've always felt that the whole concept of " discreteness " was a human illusion derived from the way we've developed problem-solving skills over our formative generations . talk ) 18 : 29, 28 October 2008 ( UTC)

In " Woman Hating : A Radical Look at Sexuality ", published in 1974, radical feminist writer and activist Andrea Dworkin called for the support of transsexuals, whom she viewed as " in a state of primary emergency " due to " the culture of male female discreteness ".
