Alt – alternating group (Alt(n) is also written as A n.) A.M. – arithmetic mean. AP – arithmetic progression. arccos – inverse cosine function. arccosec – inverse cosecant function. (Also written as arccsc.) arccot – inverse cotangent function. arccsc – inverse cosecant function. (Also written as arccosec.) arcexc – inverse ...
In order-theoretic mathematics, a series-parallel partial order is a partially ordered set built up from smaller series-parallel partial orders by two simple composition operations. [ 1 ] [ 2 ] The series-parallel partial orders may be characterized as the N-free finite partial orders; they have order dimension at most two.
The following is a list of 7400-series digital logic integrated circuits. In the mid-1960s, the original 7400-series integrated circuits were introduced by Texas Instruments with the prefix "SN" to create the name SN74xx.
Series and parallel topologies can continue to be constructed with greater and greater numbers of branches ad infinitum. The number of unique topologies that can be obtained from n ∈ N {\displaystyle n\in \mathbb {N} } series or parallel branches is 1, 2, 4, 10, 24, 66, 180, 522, 1532, 4624, … {\displaystyle \dots } (sequence A000084 in the ...
The expression series-parallel can apply to different domains: Series and parallel circuits for electrical circuits and electronic circuits; Series-parallel partial order, in partial order theory; Series–parallel graph in graph theory; Series–parallel networks problem, a combinatorial problem about series–parallel graphs
The alveolar stops /t/ and /d/ form a voiceless and voiced pair, as do the similar-sounding dental fricatives /θ/ and /ð/, though some variant systems may omit the latter pair. 2 /n/ n: Upper case N and lower case n each have two vertical strokes and two points on the baseline. 3 /m/ m: Lower case m has three vertical strokes.
Indeed, a graph has treewidth at most 2 if and only if it has branchwidth at most 2, if and only if every biconnected component is a series–parallel graph. [4] [5] The maximal series–parallel graphs, graphs to which no additional edges can be added without destroying their series–parallel structure, are exactly the 2-trees.
