vâdis, vâdiseš, vâdisâneš
Altering in the size or shape of a body. See also → deformable.
Verbal noun of → deform.
Past participle of → deform.
1) No longer in effect or use; not operating or functioning.
M.E., from O.Fr. defunct or directly from L defunctus "dead," literally "off-duty," from p.p. of defungi "to discharge, finish," from → de- "off, completely" + fungi "perform or discharge duty," from PIE root *bheug- "to enjoy" (cognates: Latin fructus).
Fr.: comète défunte
A comet that has lost its ability to emit dust and gas and no longer displays the classic cometary features of a nebulous coma and a tail, or a destroyed comet. Comet Pigott The asteroid (944) Hidalgo is considered by some to be a defunct comet because of its unusual orbit. Another case is the asteroid Phaethon.
Fr.: défuzzification, concrétisation
The process of producing a quantifiable result in a → fuzzy logic system, given → fuzzy sets and corresponding → membership functions. Defuzzification is the last step in a fuzzy logic system. After → fuzzy inferencing, the overall result is a → fuzzy value. This result should be defuzzified to obtain a final → crisp value.
1) General: Degenerate state or character. Reverting to an earlier, simpler, state.
From degener(ate), → degenerate, + -acy suffix of nouns of quality and state.
Vâgeni, from vâgen, → degenerate, + noun suffix -i.
fešâr-e vâgeni (#)
Fr.: pression de dégénérescence
Pressure in a degenerate electron or neutron gas. → degenerate matter.
Characterized by or associated with → degeneracy.
L. degeneratus, p.p. of degenerare "depart from one's kind, fall from ancestral quality," from → de- + gener-, stem of genus "race, stock, kind," gignere "to beget," cf. with Gk. genos "race, kind," gonos "birth, offspring," from PIE base *gen-/*gon-/*gn- "to produce, beget, be born," cf. Av. zan- "to bear, give birth to a child, be born," infinitive zazāite, zāta- "born," zana- "race" (in sruuô.zana- "belonging to the race of the horned ones"), O.Pers. zana- "tribe" (in paru-zana- "consisting of many tribes"), Skt. janati "begets, bears," jana- "creature, human being, race, tribe, people."
Vâgen, from vâ-, → de-, + gen "kind," (as in hamgen "of the same kind, like each other; friend, partner," from ham- "together," → com- + gen "kind," O.Pers./Av. zana- "race; tribe," cognate with L. genus, as above). Alternatively, gen may be a variant of Mid./Mod.Pers. gôn/gun "kind, type; manner; color, skin color," from Av. gaona- "hair, hair color, color."
Fr.: naine dégénérée
Same as → white dwarf.
mâdde-ye vâgen (#)
Fr.: matière dégénérée
Highly compressed matter in which the normal atomic structure has broken down and which, because of quantum-mechanical effects, exerts a pressure that is independent of temperature. Bodies with masses less than → Chandrasekhar's limit (1.4 solar masses) are supported by electron → degeneracy pressure and have densities of about 106 kg/m3. In collapsed stars of mass above 1.4 solar masses, gravity will overwhelm electron degeneracy and further collapse ensues. Electrons combine with protons to form neutrons, so producing a → neutron star. Because neutrons, like electrons, are → fermions and therefore subject to the → Pauli exclusion principle, at high enough densities, about 1014 kg/m3, neutron degeneracy pressure prevents further collapse of the star. For masses larger than 2-3 solar masses, even neutron degeneracy cannot prevent further collapse, and a → black hole is formed.
1) To lower in dignity or estimation; bring into contempt.
1) Subdivision of an interval in a scale of measurement.
From O.Fr. degré, from V.L. *degradus "a step," from L.L. degredare, from L. → de- "down" + gradus "step."
Darajé, from Ar. darajat "step, ladder."
degree of freedom
daraje-ye âzâdi (#)
Fr.: degré de liberté
degree of ionization
daraje-ye yoneš (#)
Fr.: degré d'ionisation
The number of electrons a neutral atom has lost in an ionizing physical process (radiation, shock, collision). In spectroscopy, the degree of ionization is indicated by a Roman numeral following the symbol for the element. A neutral atom is indicated by the Roman numeral I, a singly ionized atom, one which has lost one electron, is indicated by II, and so on. Thus O VI indicates an oxygen atom which has lost five electrons.
degree of polarization
Fr.: degré de polarisation
The ratio of the intensity of polarized portion of light to the total intensity at a point in the beam.
degree of stability
Fr.: degré de stabilité
degree of vertex
Fr.: degré de vertex
The act or process or an instance of dehumanizing.
Verbal noun of → dehumanize.
To deprive of → human qualities or personality.
