  Ternary - Wikipedia, the free encyclopedia
Although ternary most often refers to a system in which the three digits, 0, 1 and 2, are all nonnegative integers, the adjective also lends its name to the balanced ternary system, useful for comparison logic.
Ternary is inefficient for human usage, just as binary is. Therefore, nonary (base 9, each digit is two ternary digits) or base 27 (each digit is three ternary digits) is often used, similar to how octal and hexadecimal systems are used in place of binary.
Ternary also has a unit similar to a byte, the tryte, which is six ternary digits.

 Ternary form Information - TextSheet.com
Ternary form is a way of structuring a piece of music.
As well as marches, ternary form is often found in baroque opera arias (the so-called da capo aria) and in many dance forms, such as the sort of polkas written by the Strauss family.
It is also the form used in the minuet (or scherzo) and trio, which in the classical music era was usually the third movement of symphonies, string quartets, sonatas and similar works.

 Ternary logic - Encyclopedia.WorldSearch   (Site not responding. Last check: 2007-11-06)
Ternary logic is a multi-valued logic in which there are three truth values indicating true, false and unknown.
The negation operator should interchange truth and falsehood, while leaving the third value unchanged, since the negation of an unknown statement is still unknown.
The 27 one-variable functions in ternary logic are represented in the following table.

 Ternary Phase Diagrams   (Site not responding. Last check: 2007-11-06)
To construct a ternary diagram it is necessary to know the three binary systems for the three components.
The actual ternary diagram may be represented as a three dimensional form or more commmonly as a two dimensional projection of the liquidus surface onto the base of the triangle created when the three binary diagrams are joined together.
The fields indicated on the ternary diagram represent the primary phase fields, of solid phases in equilibrium with liquid, present on the liquidus surface.

Although ternary most often refers to a system in which the three numerals, zero, one and two, are all positive integers, the adjective also lends its name to the balanced ternary system, in which case it is useful for those seeking the representation of both positive and negative numbers.
Similarily, a currency system using balanced ternary would save visits to the bank - customers would be likely to have exact change, or be able to get a small number of coins in change, and sellers would just occasionally need to deposit a large coin or two.
Ternary is inefficient for human usage, just as binary is. Therefore, nonary (base 9, each digit is two base-3 digits) or base 27 (each digit is 3 base-3 digits) is often used, similar to how octal and hexadecimal systems are used in place of binary.

A ternary plot can be used to examine relations between four or more dimensions where three of those dimensions represent components of a mixture (i.e., the relations between them is constrained such that the values of the three variables add up to the same constant).
The responses associated with the proportions of the component variables (X, Y, and Z) in a ternary graph are plotted in a 3-dimensional display for each level of the grouping variable (or user-defined subset of data).
In this type of ternary graph, the 3-dimensional surface (fitted to a four-coordinate data set) is projected onto a 2-dimensional plane as an area contour.

 Chemical Sciences: Nomenclature: Ternary Inorganic Compounds
The basic premises of the systematic I.U.P.A.C. nomenclature of ternary compounds are similar to the ones for binary compounds.
The I.U.P.A.C. method for naming ternary compounds is to take a binary-type name using two elements, alter the ending to -ate to designate it as a non-binary compound, and then specify the number and type of added atoms as a prefix to the name or names of the element(s) to which they are attached.
Virtually all of the common ternary compounds have oxygen as one of their components, because we live in an atmosphere containing the reactive element oxygen.

 Elk-1 can recruit SRF to form a ternary complex upon the serum response element -- Latinkic et al. 24 (7): 1345 -- ...
One of the primary cellular responses to the actions of polypeptide growth factors is the rapid and transient activation of a set of immediate-early genes, which number as many as 100 in mouse 3T3 fibroblasts (1 - 3).
Recent studies on the transcriptional activation of immediate-early genes have focused on the importance of a ternary complex, comprised of SRF and TCF bound to SRE, as the integral part of the serum-responsive transcriptional apparatus (16).
Since the importance of the ternary complex was first recognized in c- fos, where SRF binds strongly to and TCF is recruited by SRF (35), TCF has been regarded as an `accessory protein' subservient to SRF (36).

 Logic - Open Encyclopedia   (Site not responding. Last check: 2007-11-06)
The logics discussed above are all "bivalent" or "two-valued"; that is, the semantics for each of these languages will assign to every sentence either the value "True" or the value "False." Systems which do not always make this distinction are known as non-classical logics or non-Aristotelian logics.
