For two sets of strings S 1 and S 2, the concatenation S 1 S 2 consists of all strings of the form vw where v is a string from S 1 and w is a string from S 2, or formally S 1 S 2 = { vw : v ∈ S 1, w ∈ S 2}. Many authors also use concatenation of a string set and a single string, and vice versa, which are defined similarly by S 1 w = { vw ...
In February 1976, work commenced to automate the methods contained in the USAF Stability and Control DATCOM, specifically those contained in sections 4, 5, 6 and 7.The work was performed by the McDonnell Douglas Corporation under contract with the United States Air Force in conjunction with engineers at the Air Force Flight Dynamics Laboratory in Wright-Patterson Air Force Base.
Link Capacity Adjustment Scheme or LCAS is a method to dynamically increase or decrease the bandwidth of virtual concatenated containers. The LCAS protocol is specified in ITU-T G.7042.
The properties of concatenative languages are the result of their compositional syntax and semantics: The reduction of any expression is the simplification of one function to another function; it is never necessary to deal with the application of functions to objects.
[2] Each frame is separated from the next by an interframe gap. A frame is a series of bits generally composed of frame synchronization bits, the packet payload, and a frame check sequence . Examples are Ethernet frames , Point-to-Point Protocol (PPP) frames, Fibre Channel frames , and V.42 modem frames.
UNIX Style, or cat -v Considered Harmful - A paper by Rob Pike on proper Unix command design using cat as an example. cat(1) original manual page in the First Edition of Unix: concatenate and write files – GNU Coreutils reference: concatenate and print files – OpenBSD General Commands Manual
Let H be a Hadamard matrix of order n.The transpose of H is closely related to its inverse.In fact: = where I n is the n × n identity matrix and H T is the transpose of H.To see that this is true, notice that the rows of H are all orthogonal vectors over the field of real numbers and each have length .
Command and control (abbr. C2) is a "set of organizational and technical attributes and processes ...[that] employs human, physical, and information resources to solve problems and accomplish missions" to achieve the goals of an organization or enterprise, according to a 2015 definition by military scientists Marius Vassiliou, David S. Alberts, and Jonathan R. Agre.
