1) Physics: Any of the distinct patterns of oscillation that a
given periodically varying system can have.
Mode, from Fr. mode, from L. modus "measure, rhythm, song, manner," from PIE base *med- "to measure, limit, judge, advise;" cf. L. meditari "to think or reflect upon, consider;" Av. mad- "to measure out, apportion, allot;" Gk. medein "to rule;" O.E. metan "to measure out."
Tarz "manner, mode," Arabicized as
1) (n.) model, tarzâl; 2) (v.) model sâxtan, tarzâlidan
Fr.: 1) modèle; 2) modéliser
1a) A mathematical representation of a process, system, or object
developed to understand its behavior or to make predictions. The
representation always involves certain simplifications and
assumptions. See also → theory,
1) Model, from Fr. modèle.
Tarzâl, from tarz, → mode + -âl,
vâbastegi bé model, ~ ~ tarzâl
Fr.: dépendance du modèle
In a theoretical analysis, the solution that does not correctly treat the intervening parameters, or neglects some crucial factors.
The simulation of a process, concept, or operation of a system often implemented by a computer program and making use of a mathematical treatment.
Verbal noun of → model
1) Relating or belonging to present and recent time.
→ modern physics.
From M.Fr. moderne, from L.L. modernus, from L. modo "lately, just now," from modo "to the measure," ablative of modus "manner, measure," → mode.
Novin, from now, → new, + -in adj. suffix, as in dirin, pasin, barin, kehin, mehin, behin, zirin, zabarin, pâyin, bâlâyin.
fizik-e novin (#)
Fr.: physique moderne
The physics developed since about 1900, which includes Einstein's → relativity theory and → quantum mechanics, as distinguished from → classical physics. Much of modern physics is concerned with the behavior of matter and energy under extreme conditions or on the very small scale.
1) Modern spirit or character.
1) An admirer of modern ideas, ways, etc.
1) The quality of being → modern.
1) The act of modernizing; the state of being modernized; something modernized.
To bring something up to modern standards, or adapt it to modern style, conditions, etc.
An act or instance of modifying; the state of being modified; partial alteration.
Verbal noun of → modify.
modified Julian date (MJD)
gâhdâd-e žulian-e vâtarzidé
Fr.: date julienne modifiée
A modification of the Julian Date, representing the number of days that have elapsed since midnight (instead of noon) at the beginning of Wednesday November 17, 1858. MJD = JD - 2,400,000.5 The reason for adopting that date is the fact that the Julian Day 2,400,000 just happens to be November 17, 1858.
MOdified Newtonian Dynamics (MOND)
tavânik-e niyutoni-ye vâtarzidé
Fr.: dynamique newtonienne modifiée
A modification of the Newton's law of gravitation below a critical acceleration of about 1.2 x 10-8 cm s-2, where the gravitational force scales as 1/r instead of 1/r2. Originally put forward to describe the rotation curves of galaxies with no need to assume any dark matter, MOND is now tested at larger cosmological scales (Milgrom, M. 1983, ApJ, 270, 365).
modified wind momentum
jonbâk-e bâd-e vâtarzidé
Fr.: moment angulaire de vent modifié
A quantity defined as Π = (dM/dt) v∞ R0.5 for a star with radius R having a wind with → terminal velocity v∞ and a → mass loss rate dM/dt. There is a tight linear relation between the modified wind momenta and the stellar luminosities for → Population I→ O stars. See also → wind momentum.
In data processing, a quantity used to alter an instruction in a prescribed way to produce the instruction actually obeyed.
Agent noun of → modify.
To change somewhat the form or qualities of; alter partially; amend.
From O.Fr. modifier, from L. modificare "to impose a rule or pattern, regulate, restrain," from modus "measure, rhythm, song, manner" PIE base *med-/*met- "to measure, limit, consider, advise, take appropriate measures" + root of facere "to make"
Vâtarzidan, from vâ- prefix denoting "reversal, opposition; separation; repetition; open; off; away" (variant of bâz-, from Mid.Pers. abâz-, apâc-; O.Pers. apa- [pref.] "away, from;" Av. apa- [pref.] "away, from," apaš [adv.] "toward the back;" cf. Skt. ápāñc "situated behind") + tarz "mode, manner" + -idan infinitive suffix.
General: To regulate by or adjust to a certain measure or proportion; tone down. Physics: To alter the value of some parameter characterizing a periodic oscillation. → modulation.
From L. modulatus pr.p. of modulari "to regulate, measure off properly," from modulus "small measure," diminutive of modus "measure, manner," → mode.
Degarâhangidan, from degar "other, another," denoting change, variant digar (Mid.Pers. dit, ditikar "the other, the second;" O.Pers. duvitiya- "second," Av. daibitya-, bitya- "second;" Skt. dvitiya- "second," PIE *duitiio- "second") + âhang "melody, pitch, tune, modulation" (ultimately from Proto-Iranian *āhang-, from prefix ā- + *hang-, from PIE base *sengwh- "to sing, make an incantation;" cf. O.H.G. singan; Ger. singen; Goth. siggwan; Swed. sjunga; O.E. singan "to chant, sing, tell in song;" maybe cognate with Gk. omphe "voice; oracle") + -idan infinitive suffix.
mowj-e degarâhangidé (#)
Fr.: onde modulée
A combination of two or more waves resulting in the production of
frequencies not present in the original waves, the new frequencies being
usually the sums and differences of integral multiples of the frequencies
in the original waves.
General: The modification of some property of a phenomenon by
another distinct phenomenon.
Verbal noun of → modulate.
