Agent noun of → amplify.
dâmané dâdan, dâmané gereftan (#)
General:To make larger, greater, or more powerful.
From M.F. amplifier, from L. amplificare "to increase, augmant," from L. amplus "wide, large."
Dâmané, → amplitude; dâdan "to give" (Mid.Pers. dâdan "to give," O.Pers./Av. dā- "to give, grant, yield," dadāiti "he gives;" Skt. dadáti "he gives," Gk. didomi "I give," tithenai "to put, set, place;" L. dare "to give, offer;" Rus. delat "to do;" O.H.G. tuon, Ger. tun, O.E. don "to do"); gereftan "to take, seize, catch," (Mid.Pers. griftan, Av./O.Pers. grab- "to take, seize," cf. Skt. grah-, grabh- "to seize, take," graha "seizing, holding, perceiving," M.L.G. grabben "to grab," from P.Gmc. *grab, E. grab "to take or grasp suddenly;" PIE base *ghrebh- "to seize").
General:The greatness, size, or extent of something.
L. amplitudo "wide extent, width," from amplus "large".
Dâmané "the foot or skirt of a mountain," from dâman "skirt."
a- (#), an- (#); bi- (#); nâ- (#)
Prefix same as → a- "not, without" occurring before a vowel or h in loanwords from Greek.
Prefix meaning: 1) up, upward (anode); 2) back, backward (ananym); 3) again, anew (anagenesis); 4) exceedingly (anamorphism).
From Gk. ana- "up, on, upon, throughout, again," cognate with Av. ana "on, over, along," O.Pers. anâ "throughout," O.E. on; PIE base *ano- "on, upon, above".
Ânâ-, from ana, anâ, Av. and O.Pers. counterparts of Gk. ana-, as above.
The shape resembling a figure of 8 obtained by following the Sun's position in the sky at the same time of day throughout the year. It is a graphical presentation of the → equation of time. Because the Earth's orbit around the Sun is elliptical, the two loops of analemma have different sizes. Analemma figures for different latitudes or different times of day would appear slightly different. The analemma is widest in the period when the Earth is closest to the Sun (December). This is because in this situation the Earth advances in its orbit faster due to the stronger gravitational attraction of the Sun. On the other hand, since the Earth rotates at a constant rate, the Sun appears to rise earlier than average because the Earth advances further in its orbit in one day when the Earth is close to the Sun. The opposite occurs in June when the Earth is further from the Sun.
From L. analemma "the pedestal of a sundial," hence the sundial itself, from Gk. analemma "prop, support," from analambanein, from → ana- "up" + lambanein "to take".
Hurspicak from hur "Sun;" Av. hvar- "sun" (cf. Skt. surya; Gk. hlios; L. sol; O.H.G. sunna; Ger. Sonne; E. sun; PIE *sawel- "sun") + picak "a curled, a twisted figure or object," from picidan "to twist, invove, enttwine, coil."
Fr.: convertisseur analogique-numérique
In electronics, a device that converts the analog signal to → analog-to-digital units or counts.
analog-to-digital unit (ADU)
Fr.: unité analogue-numérique
A number that represents a → charge-coupled device (CCD)'s output and is proportional to the → electron charge created by the → photons, plus the constant → bias offset. The relationship between the ADUs generated and the number of electrons acquired on the CCD is defined by the → CCD gain. Intensities given in ADUs provide a convenient method for comparing images and data generated by different cameras. Also referred to as → count and digital number. In most cases, the analog signal is digitalized by an analog-to-digital (A/D) converter and fed into a computer where further manipulation and analysis are done on what the detector originally produced from the star's photons (Howell, S.B., Handbook of CCD Astronomy, Cambridge Univ. Press, 2000).
Of, relating to, or based on analogy; expressing or implying analogy.
1) Similar or corresponding in some respect; having
L. analogus, from Gk. analogos "proportionate," → analogy.
ânâguyé; ânâgu, ânâguyik
Fr.: analogue, analogique
1) (n.) Something that has → analogy to something else.
From Fr. analogue, from Gk. analogon, → analogy.
Fr.: ordinateur analogique
A computer in which data is stored and processed in the form of continually varying signals representing a physical quantity rather than in the form of individual numerical values. The simplest analogue computers are side rules, thermometers, voltmeters, and speedometers.
1) A similarity or comparability between two things.
1) General: The separation of an intellectual or material whole into its
constituent parts for individual study. The study of such constituent
parts and their interrelationships in making up a whole
(opposite of → synthesis).
From M.L. analysis, from Gk. analysis "a breaking up," from analyein "unloose," from ana- "up, throughout" + lysis "a loosening," from lyein "to loosen, release, untie". The L. cognate and counterpart of this Gk. word, i.e. luere has formed the words solve, dissolve, solution. The Skt. cognate lu, lunoti "to cut, sever, mow, pluck, tear asunder, destroy," lava "cutting, plucking; what is cut; fragment, piece;" PIE *leu- "to loosen, divide, cut apart". The Eng. lose, loose and Ger. los derive from this root.
Ânâlas, from ânâ-, → ana-, +
las "loose" ([Mo'in], Gilaki, Tabari, Tâleši, Aftari). We do not
know the Av./O.Pers. counterparts of these Gk. las, lysis, lyein,
believe that las and the following words probably derive from
the above-mentioned PIE *leu-:
Of or relating to analysis, in contrast with → synthetic. Also analytical.
Pertaining to ânâlas, → analysis.
Fr.: courbe analytique
A curve whose parametric equations are real → analytic functions of a single real variable.
Fr.: fonction analytique
A function which can be represented by a convergent → power series.
Fr.: géométrie analytique
The study of the geometry of figures by algebraic representation and manipulation of equations describing their positions, configurations, and separations.
