fusion,

in physics. 1 The change of a substance from the solid to the liquid state, also known as melting. The heat given up by a unit mass of a substance during fusion is called the latent heatlatent heat,
heat change associated with a change of state or phase (see states of matter). Latent heat, also called heat of transformation, is the heat given up or absorbed by a unit mass of a substance as it changes from a solid to a liquid, from a liquid to a gas, or the

Fusion

 

in linguistics, a means of combining a stem with an affix, in which the nature of the stem is determined by the nature of the affix, or vice versa. Fusion is distinct from agglutination, which lacks such a dependence. Since the degree of dependence can vary, one may speak of the degree of fusion, which is inversely proportional to the degree of agglutination.

Fusion is said to be minimal when the affix determines only the class of the stem; for example, the Russian suffix -ost’ (“-ness”) requires an adjectival stem. Fusion is termed maximal when the combination of stem and affix influences the selection of a particular morph for the stem or for the affix, in both inflection and word formation. In inflection, compare Russian vid-ish’ (“you see,” sing.) with vizh-u (“I see”) and id-esh’ (“you are going,” sing.); compare Greek π∈πoμφ-α (“I sent,” perf.) with π∈μπ-ω (“I send”). In word formation, compare English “depth” and “deep.” The term “fusion” is often used only to designate the latter phenomenon, that is, maximal fusion. Languages in which inflected forms are formed by means of fusion are called fusional languages.

fusion

[′fyü·zhən]
(nuclear physics)
Combination of two light nuclei to form a heavier nucleus (and perhaps other reaction products) with release of some binding energy. Also known as atomic fusion; nuclear fusion.
(physical chemistry)
A change of the state of a substance from the solid phase to the liquid phase. Also known as melting.

fusion

In welding, the melting together of filler metal and base metal, or of the base metal alone, which results in coalescence.

3. Psychol the processing by the mind of elements falling on the two eyes so that they yield a single percept

FUSION

Software package supplied by Network Research Corporation claiming to connect various different configurations of LAN.

fusion

(programming)
A program transformation where a composition of two functions is replaced by in-lining them and combining their bodies. E.g.

f x = g (h x) ==> f x = g (2 * x) g x = x + 1 f x = 2 * x + 1 h x = 2 * x

This has the beneficial effect of reducing the number of function calls. It can be especially useful where the intermediate result is a large data structure which can be eliminated.

See also vertical loop combination.
