Coherence length is usually applied to the optical regime.

Coherence time, τ, is calculated by dividing the coherence length by the phase velocity of light in a medium ; approximately given by

This equation is just an approximation, to be exact, see Coherence time.

Once the fringes are obtained in the Michelson – Morley experiment, when one of the mirrors is moved away gradually, the time for the beam to travel increases and the infringes become dull and finally are lost, showing Temporal Coherence.

Coherence was originally conceived in connection with Thomas Young's double-slit experiment in optics but is now used in any field that involves waves, such as acoustics, electrical engineering, neuroscience, and quantum mechanics.

The theory is applicable to all organizationally closed or homeostatic processes that produce endurance and coherence ( also in the sense of Rescher Coherence Theory of Truth with the proviso that the sets and their members exert repulsive forces at their boundaries ) through interactions: evolving, learning and adapting.

Coherence of particles by radio waves is an obscure phenomenon that is not well understood even today.

Coherence length is low ( typically < 1 mm ) and the typical linewidth is in the nm-range.

Coherence of sheaves is working in the background of some results in commutative algebra, e. g. Nakayama's lemma, which in terms of sheaves says that if is a coherent sheaf, then the fiber if and only if there is a neighborhood of so that.

Optical Coherence Tomography, or ‘ OCT ’, is a technique for obtaining sub-surface images of translucent or opaque materials at a resolution equivalent to a low-power microscope.

# Coherence: " if material from the earlier strata of tradition is consonant with other material already established as probably authentic, then it too is probably authentic.

Optical Coherence Tomography ( OCT ) is another NIR medical imaging technique capable of 3D imaging with high resolution on par with low-power microscopy.

* Coherence is a complete UPnP python framework including a DMS, a DMR, and a DMC.

* Coherence is a framework written in Python to enable applications access to digital living network resources.

A continuation and subset of the Subtext language using other principles, is Coherence, an experimental programming language and environment, which uses a new model of change-driven computation called " Coherent reaction ", to coordinate the effects and side-effects of programs interactively as they are being developed.

The fundamental building block of Coherence is the dynamically typed mutable tree.

Coherence in linguistics is what makes a text semantically meaningful.

Coherence is achieved through syntactical features such as the use of deictic, anaphoric and cataphoric elements or a logical tense structure, as well as presuppositions and implications connected to general world knowledge.

Coherence bandwidth is a statistical measurement of the range of frequencies over which the channel can be considered " flat ", or in other words the approximate maximum bandwidth or frequency interval over which two frequencies of a signal are likely to experience comparable or correlated amplitude fading.

Coherence can be best defined as the degree to which a story makes sense structurally.

* Coherence – defined as thinking, feeling and acting in the same way.

Coherence theories distinguish the thought of rationalist philosophers, particularly of Spinoza, Leibniz, and G. W. F.

Closed-loop mirror galvanometers are also used in stereolithography, in laser sintering, in laser engraving, in laser beam welding, in laser TV, in laser displays, and in imaging applications such as Optical Coherence Tomography ( OCT ) retinal scanning.

Coherence was a design aim of SI resulting in only one unit of energy being defined-the joule.

Cache Coherence, implemented using the MESI protocols, was very complicated but significantly improved performance.

Coherence defines the behavior of reads and writes to the same memory location.

To minimize latency and avoid bottlenecks, distributed computing can benefit significantly from distributed caches like AppFabric Caching Service, NCache, Oracle Coherence, IBM WebSphere eXtreme Scale, Memcached, Ehcache etc.

It is softened by the saltbush and the bluebush, has a peaceful quality, the hills roll softly.

The process stipulates that the choreographer sense the quality of the initial movement he has discovered and that he feel the rightness of the quality that is to follow it.

The personal quality of Samuel Beckett is similar to qualities I had found in the plays.

All such imitations of negative quality have given rise to a compensatory response in the form of a heroic and highly individualistic humanism: if man can neither know nor love reality as it is, he can at least invent an artistic `` reality '' which is its own world and which can speak to man of purely personal and subjective qualities capable of being known and worthy of being loved.

As long as perception is seen as composed only of isolated sense data, most of the quality and interconnectedness of existence loses its objectivity, becomes an invention of consciousness, and the result is a philosophical scepticism.

You could also say that in these pamphlets is a relieving quality of maturity.

Perhaps it is only an analogy, but one of the most obvious differences between cheap fiction and fiction of an enduring quality is the development of a theme or story with leisure and anticipation.

In the calm which follows the reading of a poem, for example, is the effect produced by the enforced quiet, by the musical quality of words and rhythm, by the sentiments or sense of the poem, by the associations with earlier readings, if it is familiar, by the boost to the self-esteem for the semi-literate, by the diversion of attention, by the sense of security in a legitimized withdrawal, by a kind license for some variety of fantasy life regarded as forbidden, or by half-conscious ideas about the magical power of words??

Sensibility is a vague word, covering an area of meaning rather than any precise talent, quality, or skill.

He tends to underestimate -- or perhaps to view charitably -- the brutality and the violence of the age, so that there is an idyllic quality in these pages which hazes over some of its sharp reality.

It is this larger theme of the `` quality of man '', a quality that transcends the ideological and flows into `` the human '', which now forms the pulsating heart of Malraux's artistic universe.

Besides the lack of an adequate ethical dimension to the Governor's case, one can ask seriously whether our lead over the Russians in quality and quantity of nuclear weapons is so slight as to make the tests absolutely necessary.

I am firmly convinced that considering the average quality of teachers in this country, the profession is grossly overpaid.

He could no longer build anything, whether a private residence in his Pennsylvania county or a church in Brazil, without it being obvious that he had done it, and while here and there he was taken to task for again developing the same airy technique, they were such fanciful and sometimes even playful buildings that the public felt assured by its sense of recognition after a time, a quality of authentic uniqueness about them, which, once established by an artist as his private vision, is no longer disputable as to its other values.

In view of the increasing shortage of usable surface and ground water in many parts of the Nation and the importance of finding new sources of supply to meet its present and future water needs, it is the policy of the Congress to provide for the development of practicable low-cost means for the large-scale production of water of a quality suitable for municipal, industrial, agricultural, and other beneficial consumptive uses from saline water, and for studies and research related thereto.

This program is based on the policy of designing and building efficient machines which will help produce better textile values -- fabrics whose cost in relation to quality, fashion and utility provide the consumer with better textile products for the money.

Because the bobbin-to-cone winding process is a relatively high-cost operation for the mill, the almost complete automation provided by the Uniconer can mean important economies in textile production, at the same time upgrading quality.

Another growth factor is increased consumer demand for better quality and larger quantities of fabrics that go with a rising standard of living.

The quality of a president's leadership is measured first by his success in building up the faculty.
