Fr.: fonction imbriquée
In computer programing, a function that is defined inside the definition of another function.
Fr.: multiplication imbriquée
A method in the evaluation of polynomials which involves fewer basic operations and allows simpler computation, especially for polynomials of high degree. More specifically, the polynomial P(x) = a0 + a1x + a2x2 + a3x3 + ... + anxn can be written in the nested form as: P(x) = a0 + x(a1 + x(a2 + ... + x(an - 1 + anx) ...)). For example, the polynomial P(x) = x3 - 5x2 + 10x - 3 has the following nested form: P(x) = ((x - 5)x + 10)x - 3. Same as the → Ruffini-Horner method.
Any net-like combination of elements in a system; an interconnection of several communicating entities.
O.E. net "mesh," from P.Gmc. *natjan (cf. Du. net, Swed. nät, O.H.G. nezzi, Ger. Netz, Goth. nati "net"), originally "something knotted," from PIE *ned- "to twist, knot" (cf. L. nodus "knot;" Skt. nahyati "binds, ties") + → work.
Turbast literally "joined, tied by a net," from tur "net, fishing net, snare," related to târ "thread, warp, string," tâl "thread" (Borujerdi dialect), tân "thread, warp of a web," from tanidan, tan- "to spin, twist, weave" (Mid.Pers. tanitan; Av. tan- to stretch, extend;" cf. Skt. tan- to stretch, extend;" tanoti "stretches," tántra- "warp; essence, main point;" Gk. teinein "to stretch, pull tight;" L. tendere "to stretch;" Lith. tiñklas "net, fishing net, snare," Latv. tikls "net;" PIE base *ten- "to stretch") + bast "joined, tied," from bastan, vastan "to bind, shut" (O.Pers./Av. band- "to bind, fetter," banda- "band, tie" (cf. Skt. bandh- "to bind, tie, fasten;" PIE *bhendh- "to bind;" Ger. binden; E. bind).
Fr.: raie de Neumann
In → iron meteorites, any of very fine parallel lines that cross each other at various angles. They can be seen after cutting diagonally across the sample.
Named after Johann G. Neumann, who discovered them in 1848 in the iron meteorite Braunau, which fell in 1847; → line.
Grammar: Noting or pertaining to a gender that refers to things classed
as neither masculine nor feminine.
From M.E., from M.Fr., from L. neuter, literally "neither one nor the other," from ne- "not, no" + uter "either of two;" cf. Av. atāra- "this of the two, which of the two;" Gk. poteros; Lith. katras "which of the two," Russ. kotoryj "which."
Natâr, from negation prefix na-, → non-, + Mid.Pers. atâr, from Av. atāra- "this of the two," cognate with L. uter "either of two;" Av. katāra- "which of two; each of two;" Skt. katará- "who or which of two."
Of an atom, molecule, collection of particles, having no net charge; not electrified.
Fr.: atome neutre
neutral density filter
pâlâye-ye cagâli-ye natâr
Fr.: filtre neutre
A filter having a flat response over the range of wavelengths of interest. Also called neutral filter or gray filter.
Fr.: filtre neutre
Same as → neutral density filter.
Fr.: gaz neutre
A gas which is not ionized.
Fr.: hydrogène neutre
Non-ionized → atomic hydrogen gas which constitutes an important component of the → interstellar medium, accounting for perhaps half its mass, even though its density is very low. Its radio emission → 21-centimeter line has made it possible to map the distribution of neutral hydrogen in the → spiral arms of our own Galaxy and other nearby galaxies.
mod-e natâr, tarz-e ~
Fr.: mode neutre
In hydrodynamic instability theory, a wave solution the amplitude of which does not change with time; it neither grows nor decays. Also called neutral wave.
Fr.: point neutre
1) A point where two fields are equal in magnitude and opposite in direction so
that the net force exerted on it is zero.
dom-e natâr, donbâle-ye ~
Fr.: queue neutre
Same as → sodium tail.
Fr.: onde neutre
Same as → neutral mode.
A hypothetical particle predicted by supersymmetry theories, which aim at relating bosons to fermions. Under certain assumptions, the lightest such partner particle would be stable, and if it is neutral (a "neutralino"), would make a good dark matter candidate. Reasonable neutralino masses range from 30 GeV to 10 TeV.
From → neutral + -ino diminutive suffix.
In optics, the process of combining two lenses having equal and opposite powers to produce a result having no power.
Verbal noun of → neutralize.
To make neutral; cause to undergo neutralization.
Infinitive from → neutral.
An → elementary particle with zero
→ charge, → spin 1/2, and
very small → rest mass.
The three types of neutrino (electron neutrino, muon neutrino, tau neutrino)
experience only the → weak nuclear force
and gravitational force, and pass easily through matter.
The neutrino undergoes a quantum mechanical phenomenon in which
→ neutrino flavor changes spontaneously to another flavor
(→ neutrino oscillation).
The neutrino was first postulated by Wolfgang Pauli in 1931 to account for the
problem of energy → conservation
in → beta decay. It was discovered in 1956.
Neutrino, coined by Enrico Fermi (1901-1954), from neutr(o)→ neuter + -ino diminutive suffix.
Fr.: saveur de neutrino
Any of the six different varieties of the neutrinos: electron neutrinos, muon neutrinos, tau neutrinos, and their antiparticles.
