1. Consisting of or marked by only one part or element.
2. Of or relating to a telecommunications system in which only one message can be sent in either direction at one time.
n. pl. sim·plex·es or sim·pli·ces (-plĭ-sēz′)
1. Mathematics A Euclidean geometric spatial element having the minimum number of boundary points, such as a line segment in one-dimensional space, a triangle in two-dimensional space, or a tetrahedron in three-dimensional space.
2. Linguistics A word that has no affixes and is not part of a compound; a simple word.

[Latin, simple; see sem- in Indo-European roots.]


(Telecommunications) permitting the transmission of signals in only one direction in a radio circuit, etc. Compare duplex
n, pl simplexes or simplicia (sɪmˈplɪʃə)
1. (Linguistics) linguistics a simple not a compound word
2. (Mathematics) geometry the most elementary geometric figure in Euclidean space of a given dimension; a line segment in one-dimensional space or a triangle in two-dimensional space
[C16: from Latin: simple, literally: one-fold, from sim- one + plex, from plicāre to fold; compare duplex]


(ˈsɪm plɛks)

(2010)) Every generalized permutahedron can be written uniquely as a Minkowski sum and difference of faces of the standard simplex: Z({[z.sub.I]}) = Y({[y.sub.I]}), where [y.sub.I] = [[summation].sub.J[subset]I][(-1).sup.[absolute value of I\J]] [z.sub.J] if all inequalities [[summation].sub.i[member of]I] [x.sub.i] [greater than or equal to] [z.sub.I] defining Z({[z.sub.I]}) are tight.
It raises the question to compute efficiently their Minkowski decomposition into dilates of faces of the standard simplex. This question was recently addressed by Lange (2011) for the special sorting networks whose brick polytopes are associahedra and which we present in the next section.
The harness assembly is a four-, six-, eight- or 12-fiber drop cable factory-terminated on one end with a non-pinned hardened array connector and a standard simplex connector type on the other end.
