  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 digit (One of the elements that collectively form a system of numbers) s are known as trits (trinary digit), analogous to bit (The cutting part of a drill; usually pointed and threaded and is replaceable in a brace or bitstock or drill press).
Although ternary most often refers to a system in which the three numerals,, and, are all positive integers (additional info and facts about positive integers), the adjective also lends its name to the balanced ternary system, useful for comparison logic.
Ternary also has the equivalent of a byte (A sequence of 8 bits (enough to represent one character of alphanumeric data) processed as a single unit of information), called a tryte (additional info and facts about tryte).

 Ternary logic   (Site not responding. Last check: 2007-10-10)
Ternary logic is a multi-valued logic in which there are three states, thus the ternary numeral system is used to represent ternary logic equations.
The 27 one-variable functions in ternary logic are represented in the following table.
We may imagine a ternary computer, whose operation is similar to a binary computer, but making use of ternary logic; each basic location in the computer's memory would be called a "trit", by analogy with a "bit".

 Development of ternary computers at Moscow State University
Now, when the binary computers predominate, it is hard to believe in a reality of such assumption, but if it would happen not only the computer arithmetic, but the informatics on the whole would become most simple and most perfect.
For such goal at the computer center of the University there was formed a group of young men (4 MS and 5 BA).
Due to the low reliability of the computer elements on vacuum tubes and inaccessibility of transistors the fast elements on miniature ferrite cores and semiconductor diodes were designed.

The ternary identification number is then converted to a binary identification number, which is then stored on a storage medium accessed by the computer, wherein the binary number serves as a representation of the genotype of the given individual.
As a result, a ternary code of an unknown individual may be converted to a binary number and compared to the existing database of binary numbers to identify the unknown individual if a match exists.
Alternatively, the ternary code may be converted to a decimal number, or conceivably any other base number, which will compress the code into a smaller number that could, for example, serve as an identification number for each individual to whom the number corresponds.

 .NET Undocumented: Ternary Systems
Ternary values consist of the values 1,0,-1 which correspond respectively to the quasi-boolean values—true, unknown, false.
However, ternary values can yet be represented as an even more general value in fuzzy logic with states corresponding to the inclusive range of real numbers between 0 and 1.

 The main principles of the Fibonacci computer design
It was determined that just the failure of the control computer of the rocket "Atlas" that carried the first American cosmic station "Mariner -1" made the rocket deviate from the true course.
The central idea of the fault-tolerant computers is an introduction of the hardware and code redundancy permitting to detect the faults and failures arising within the computer circuits.
Hence the main purpose of the Fibonacci computer is the high reliability assurance of the information processing by using the redundancy of the Fibonacci and "Golden" codes.

On the hypothesis that a computer’s component count would be roughly proportional both to the width and to the depth of the numbers being processed, they suggested that rw might be a good predictor of hardware cost, and so ternary notation would make the most efficient use of hardware resources.
Ternary computers were a fad that faded, though not quickly.
Ternary also distinguishes between even and odd, but the signal is subtler: A ternary numeral represents an even number if the numeral has an even number of 1s.

 The Thermodynamic Modeling of Multicomponent Phase Equilibria
Phase diagrams are visual representations of the state of a material as a function of temperature, pressure, and concentrations of the constituent components and are, therefore, frequently hailed as basic blueprints or roadmaps for alloy design, development, processing, and understanding.
In recent years, the expression "computational thermodynamics" is frequently used in place of "calculation of phase diagrams." This reflects the fact that the phase diagram is only a portion of the information that can be obtained from these calculations.
Thermodynamic calculation of the phase equilibria of a multicomponent alloy was interfaced with a micromodel for computing the change of fraction solid and temperature, given a specified change in enthalpy during the liquid-solid transformation.

 Brousentsov's Ternary Principle
The question is of the ternary symmetrical number system used by the Russian engineer Nickolai Brousentsov in the project of the "Setun" computer designed under his supervision at the Moscow University in the 50th years of the 20th century.
The "Setun" computer had been designed on magnetic elements and therefore it did not get the wide practical usage but its architecture based on the "ternary principle" was so perfect that at the present time the project of the "Setun" computer still attracts attention of many computer specialists.
As soon as such elements are developed the majority of computers of the universal kind and many special computers most probably will be designed so that they would function in the ternary symmetrical number system".
