Coherence, coherency, or coherent may refer to the following,:
In physics, two wave sources are perfectly coherent if they have a constant phase difference and the same frequency. It is an ideal property of waves that enables stationary (i.e. temporally and spatially constant) interference. It contains several distinct concepts, which are limiting cases that never quite occur in reality but allow an understanding of the physics of waves, and has become a very important concept in quantum physics. More generally, coherence describes all properties of the correlation between physical quantities of a single wave, or between several waves or wave packets.
Interference is nothing more than the addition, in the mathematical sense, of wave functions. A single wave can interfere with itself, but this is still an addition of two waves (see Young's slits experiment). Constructive or destructive interferences are limit cases, and two waves always interfere, even if the result of the addition is complicated or not remarkable.
When interfering, two waves can add together to create a wave of greater amplitude than either one ( constructive interference) or subtract from each other to create a wave of lesser amplitude than either one ( destructive interference), depending on their relative phase. Two waves are said to be coherent if they have a constant relative phase. The amount of coherence can readily be measured by the interference visibility, which looks at the size of the interference fringes relative to the input waves (as the phase offset is varied); a precise mathematical definition of the degree of coherence is given by means of correlation functions.
Spatial coherence describes the correlation (or predictable relationship) between waves at different points in space, either lateral or longitudinal. Temporal coherence describes the correlation between waves observed at different moments in time. Both are observed in the Michelson–Morley experiment and Young's interference experiment. 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 fringes become dull and finally are lost, showing temporal coherence. Similarly, if in Young's double slit experiment the space between the two slits is increased, the coherence dies gradually and finally the fringes disappear, showing spatial coherence.
In a thought experiment proposed by the Italian probabilist Bruno de Finetti in order to justify Bayesian probability, an array of wagers is coherent precisely if it does not expose the wagerer to certain loss regardless of the outcomes of events on which he is wagering, even if his opponent makes the most judicious choices.
In probability theory and statistics, coherence can have several different meanings.
Coherence in linguistics is what makes a text semantically meaningful. It is especially dealt with in text linguistics. 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. The purely linguistic elements that make a text coherent are subsumed under the term cohesion.
However, those text-based features which provide cohesion in a text do not necessarily help achieve coherence, that is, they do not always contribute to the meaningfulness of a text, be it written or spoken. It has been stated that a text coheres only if the world around is also coherent.
Robert De Beaugrande and Wolfgang U. Dressler define coherence as a “continuity of senses” and “the mutual access and relevance within a configuration of concepts and relations”. Thereby a textual world is created that does not have to comply to the real world. But within this textual world the arguments also have to be connected logically so that the reader/hearer can produce coherence.
"Continuity of senses" implies a link between cohesion and the theory of Schemata initially proposed by Bartlett in 1932Bartlett, F.C. (1932).
Remembering: A study in experimental and social psychology. Cambridge: Cambridge University Press which creates further implications for the notion of a "text". Schemata, subsequently distinguished into Formal and Content Schemata (in the field of TESOL) are the ways in which the world is organized in our minds. In other words, they are mental frameworks for the organization of information about the world. It can thus be assumed that a text is not always one because the existence of coherence is not always a given. On the contrary, coherence is relevant because of its dependence upon each individual's content and formal schemata.
The spectral coherence is a statistic that can be used to examine the relation between two signals or data sets. It is commonly used to estimate the power transfer between input and output of a linear system. If the signals are ergodic, and the system function linear, it can be used to estimate the causality between the input and output.
Coherence is an open-source license multimedia computer application developed under the MIT system. As a stand-alone application, Coherence performs as a DLNA/ UPnP Media Server. Coherence has an in-built capability to export local files or online media via its back ends to other UPnP clients. With supported clients, Coherence functions as a controllable DLNA/ UPnP MediaRenderer. Coherence can also function as a Python framework to enable other applications to access digital-living networks and resources.
A coherent derived unit is defined as a derived unit that, for a given system of quantities and for a chosen set of base units, is a product of powers of base units with no other proportionality factor than one. The concept of coherence was developed in the mid-nineteenth century by, amongst others, Kelvin and James Clerk Maxwell and promoted by the British Association for the Advancement of Science. The concept was initially applied to the centimetre–gram–second (CGS) and the foot–pound–second systems (FPS) of units in 1873 and 1875 respectively. The International System of Units (1960) was designed around the system of coherence.
Coherence is an American science fiction horror film directed by James Ward Byrkit in his directorial debut. The film had its world debut on September 19, 2013 at the Austin Fantastic Fest and stars Emily Baldoni as a woman who must deal with strange occurrences following a comet sighting.
Usage examples of "coherence".
Coherence was achieved because the men who created the system all used the same, ever-growing body of textbooks, and they were all familiar with similar routines of lectures, debates and academic exercises and shared a belief that Christianity was capable of a systematic and authoritative presentation.
Indeed, one of the consequences of this change, by which an etymological, dynastic notion of linguistic filiation was pushed aside by the view of language as a domain all of its own held together with jagged internal structures and coherences, is the dramatic subsidence of interest in the problem of the origins of language.
