Two other uncommon sources were promoted by Alexander: Anselm of Canterbury, whose writings had been ignored for almost a century gained an important advocate in Alexander and he used Anselm's works extensively in his teaching on Christology and soteriology ; and, Pseudo-Dionysius the Areopagite, whom Alexander used in his examination of the theology of Orders and ecclesiastical structures.

Two long papers published in 1840 — one on attractions and Clairaut's theorem, and the other on the variation of gravity at the surface of the earth — also demand notice, as do his mathematical memoirs on the critical values of sums of periodic series ( 1847 ) and on the numerical calculation of a class of definite integrals and infinite series ( 1850 ) and his discussion of a differential equation relating to the breaking of railway bridges ( 1849 ), research related to his evidence given to the Royal Commission on the Use of Iron in Railway structures after the Dee bridge disaster of 1847.

Two Lewis structures must be drawn: Each structure has one of the two oxygen atoms double-bonded to the nitrogen atom.

Two pseudoknot RNA structures were predicted that include the 3 ' splice site in Segments 7 and 8, which are both alternatively spliced to produce the M2 and NEP proteins respectively.

Two of the 100 listed buildings and structures in the Borough of Crawley are in Southgate.

Associative operations are abundant in mathematics ; in fact, many algebraic structures ( such as semigroups and categories ) explicitly require their binary operations to be associative.

A binary operation is a binary function where the sets X, Y, and Z are all equal ; binary operations are often used to define algebraic structures.

Some structures are adopted by a number of compounds ; for example, the structure of the rock salt sodium chloride is also adopted by many alkali halides, and binary oxides such as MgO.

Further, the generative theory has several hypothetical constructs ( such as movement, empty categories, complex underlying structures, and strict binary branching ) that cannot possibly be acquired from any amount of linguistic input.

Government Phonology, which originated in the early 1980s as an attempt to unify theoretical notions of syntactic and phonological structures, is based on the notion that all languages necessarily follow a small set of principles and vary according to their selection of certain binary parameters.

Alternatively, when a self-balancing binary search tree is used, insertion and removal also take O ( log n ) time, although building trees from existing sequences of elements takes O ( n log n ) time ; this is typical where one might already have access to these data structures, such as with third-party or standard libraries.

The precise nature of the revision or critique of structuralism differs with each post-structuralist author, though common themes include the rejection of the self-sufficiency of the structures that structuralism posits and an interrogation of the binary oppositions that constitute those structures.

To properly understand or process it the recipient must know ( or be able to figure out ) what encoding was used ; however, they need not know anything about the computer architecture that was used, or about the binary structures defined by whatever program ( if any ) created the data.

Lévi-Strauss included this in his conceptualization of the universal structures of the mind, which he held to operate based on pairs of binary oppositions such as hot-cold, male-female, culture-nature, cooked-raw, or marriageable vs. tabooed women.

* AVL tree, red-black tree, and splay tree, kinds of binary search tree data structures that use rotations to maintain balance.

Tarjan has also developed important data structures such as the Fibonacci heap ( a heap data structure consisting of a forest of trees ), and the splay tree ( a self-adjusting binary search tree ; co-invented by Tarjan and Daniel Sleator ).

The most common data structures are binary space partitions, octrees, and cell and portal culling.

A common claim within ecofeminist literature is that patriarchal structures justify their dominance through binary opposition, these include but are not limited to: heaven / earth, mind / body, male / female, human / animal, spirit / matter, culture / nature and white / non-white.

A standard solution to the dictionary problem is a hash table ; in some cases it is also possible to solve the problem using directly addressed arrays, binary search trees, or other more specialized structures.

Many larger forms incorporate binary structures, and many more complicated forms ( such as sonata forms ) share certain characteristics with binary form.

In full generality, algebraic structures may involve an arbitrary number of sets and operations of higher arity, but this article focuses on binary operations on one or two sets.

Simple structures: No binary operation:

Group-like structures: One binary operation.

Module-like structures: composite systems involving two sets and employing at least two binary operations.
