English-French-Persian

Same as → angular diameter distance.

→ angular; → size; → distance.

To give → emphasis to; lay stress upon; stress (Dictionary.com).

→ emphasis + → -ize.

To form a → hypothesis.

Hypothesize, from hypothes(is), → hypothesis + -ize a verb-forming suffix, from M.E. -isen, from O.Fr. -iser, from L.L. -izare, from Gk. -izein.

Engâré sâxtan, from engâré, → hypothesis + sâxtan, sâzidan "to adapt, adjust, be fit; to build, make, fashion," Mid.Pers. sâxtan, sâz-, Manichean Parthian s'c'dn "to prepare, to form," Av. sak- "to understand, to mark," sâcaya- (causative) "to teach."
Upâdâyanidan, infinitive from upâdâyan, → hypothesis.

The real, physical size, as opposed to angular size.

→ linear; → size.

The relation between the stellar luminosity of a galaxy and its physical size. More at → mass-size relation.

→ luminosity; → size; → relation.

The relation between the → stellar mass and the physical size of a galaxy. Studies show that the sizes increase with stellar mass, but that the relation weakens with increasing → redshift. Separating galaxies by their → star formation rate, model simulations show that → passive galaxies are typically smaller than → active galaxies at a fixed stellar mass. These trends are consistent with those found in observations; the level of agreement between the predicted and observed size-mass relations is of the order of 0.1 dex for redshifts < 1 and 0.2-0.3 dex from redshift 1 to 2. Known also as the → luminosity-size relation (Furlong et al., 2016, MNRAS 465, 722, and references therein).

→ mass; → size; → relation.

Produce through → nucleosynthesis.

→ nucleosynthesis; → -ize.

The number of sampling units which are to be included in the sample. In the case of a multi-stage sample this number refers to the number of units at the final stage in the sampling.

→ sample; → size.

The spatial dimensions, extent, proportions, amount, or degree of something.

M.E. syse originally "control, regulation, limit," from O.Fr. sise shortened form of assise "session, regulation, manner."

1) Andâzé "measure, size" from Mid.Pers. andâzag, handâcak "measure," handâxtan, handâz- "to measure," Manichean Mid.Pers. hnds- "to measure," Proto-Iranian *hamdas-, from ham-, → com-, + *das- "to heap, amass;" cf. Ossetic dasun/dast "to heap up;" Arm. loanword dasel "to arrange (a crowd, people)," das "order, arrangement,"

The number of → edges.

→ size; → graph.

A quantity that defines the type of → scattering.

→ size; → parameter.

To form a material or abstract entity by combining parts or elements; opposite of → analysis.
Chemistry: To combine (constituent elements) into a single or unified entity.

From → synthesis + → -ize.

Handâyidan, verbal form of handâyeš, → synthesis.

A person or thing that synthesizes.
