Duplex printing is a feature of some computer printers and multi-function printers (MFPs) that allows the printing of a sheet of paper on both sides automatically. Print devices without this capability can only print on a single side of paper, sometimes called single-sided printing or simplex printing .
The simplex algorithm applied to the Phase I problem must terminate with a minimum value for the new objective function since, being the sum of nonnegative variables, its value is bounded below by 0. If the minimum is 0 then the artificial variables can be eliminated from the resulting canonical tableau producing a canonical tableau equivalent ...
For example, a 0-dimensional simplex is a point, a 1-dimensional simplex is a line segment, a 2-dimensional simplex is a triangle, a 3-dimensional simplex is a tetrahedron, and; a 4-dimensional simplex is a 5-cell. Specifically, a k-simplex is a k-dimensional polytope that is the convex hull of its k + 1 vertices.
Klee Minty cube for shadow vertex simplex method. The Klee–Minty cube or Klee–Minty polytope (named after Victor Klee and George J. Minty) is a unit hypercube of variable dimension whose corners have been perturbed.
Two Tahitian Women (1899) by Paul Gauguin. The word "topless" usually refers to a woman whose breasts, including her areolas and nipples, are exposed to public view. It can describe a woman who appears, poses, or performs with her breasts exposed, such as a "topless model" or "topless dancer", or to an activity undertaken while not wearing a top, such as "topless sunbathing".
A duplex communication system is a point-to-point system composed of two or more connected parties or devices that can communicate with one another in both directions. Duplex systems are employed in many communications networks, either to allow for simultaneous communication in both directions between two connected parties or to provide a reverse path for the monitoring and remote adjustment ...
122.168.214.130 20:27, 4 September 2008 (UTC)Acctually the simplex is used for one way communication at one time while the duplex can communicate another at other instant. I am unable to find an ITU-T definition of simplex that is equivalent to half-duplex. See, for example, this page : Query Definitions.
Simplex graphs were introduced by Bandelt & van de Vel (1989), [3] who observed that a simplex graph has no cubes if and only if the underlying graph is triangle-free, and showed that the chromatic number of the underlying graph equals the minimum number n such that the simplex graph can be isometrically embedded into a Cartesian product of n trees
