acuity
  تیزنایی   
tiznâyi (#)

Fr.: acuité   

Sharpness; acuteness; keenness of perception.

M.E., from M.Fr. acuité, from M.L. acuitatem (nom. acuitas) "sharpness," from L. acus "needle," acuere "to sharpen," from PIE root *ak- "be sharp."

Tiznâ "sharpness," from tiz, "→ sharp," + -nâ, a suffix that transforms adjective into noun (compare with tangnâ, derâznâ, farâxnâ, etc.).

acuity of vision
  تیزنایی ِ دید   
tiznâ-ye did

Fr.: acuité visuelle   

The ability of the → eye to see separately two points close to each other. It is a measure of the → resolving power of the eye's → optical system and depends on the density of cells in the → retina. The maximum acuity of the normal human eye is around 0.5 minutes of arc.

acuity; → vision.

ad hoc
  پدیم   
pad im

Fr.: ad hoc   

For the specific purpose at hand, as opposed to a general solution; also, by extension, improvised or impromptu.

From L. ad "to, with, in," cf. Skt. adhi "near," PIE *ad- "to, near, at."

Pad im, from Mid.Pers. pad "to, at, for, in" (Mod.Pers. "to, for, in, on, with, by"); O.Pers. paity "agaist, back, opposite to, toward, face to face, in front of;" Av. paiti "to, toward, in, at;" cf. Skt. práti "toward, against, again, back, in return, opposite;" Pali pati-; Gk. proti, pros "face to face with, toward, in addition to, near;" PIE *proti) + Mid.Pers. im "this;" from Old.Pers./Av. ima "this;" Skt. imá; cf. Lori (Laki) im "this side." The Mid.Pers. im occurs in Mod.Pers. as em- in emruz "today," emšab "tonight," and emsâl "this year."

ad hoc hypothesis
  انگاره‌ی ِ پدیم   
engâre-ye pad im

Fr.: hypothèse ad hoc   

Addition of adjustments to a theory to save it from being falsified by compensating for anomalies not anticipated by the theory in its unmodified form. Theories that rely on continual, ad hoc adjustments are distrusted.

ad hoc; → hypothesis.

ad hominem
  پد مرت   
pad mart

Fr.: ad hominem   

A fallacious objection to an argument or factual claim by appealing to a characteristic or belief of the person making the argument or claim, rather than by addressing the substance of the argument or producing evidence against the claim (wiktionary).

Literally "to a man," from → ad- "to," + hominem, accusative of homo "man," → human.

Pad mart, literally "to a man," from pad "to," → ad hoc, + mart, → man.

adapt
  نیاویدن   
niyâvidan

Fr.: adapter, s'adapter   

To make suitable to or fit for a specific use or situation.

From M.Fr. adapter, from L. adaptare "adjust," from ad- "to" + aptare "join," from aptus "fitted."

Niyâvidan from Mid. Pers. niyâw "apt, suitable, appropriate" + -idan verb making suffix.

adaptive mesh refinement (AMR)
  نازکش ِ نیاوشی ِ بانچه   
nâzokeš-e niyâveši-ye bâncé

Fr.: raffinement de maillage adaptatif   

A type of → algorithm that dynamically achieves high → resolution in localized regions of multidimensional → numerical simulations. AMR provides a higher → accuracy solution at lower costs, through an automatically → optimal distribution of → grid points for the computation region. It relies on locally refined mesh or mesh patches to increase the resolution of an underlying coarse mesh only where needed. It can alleviate some of the complexities of the generation of high quality grid and reduce the number of → iterations of "trial-and-error" between the grid generation and solution required for tailoring the grid to the specification of a problem. Thus, it can offer orders of magnitude saving in computational and storage costs over an equivalent uniformly refined mesh. AMR was originally developed for → inviscid, → compressible flow (Berger et al., 1984, Adaptive Mesh Refinement for Hyperbolic Partial Differential Equations. J. Comp. Phy., 53, 484). It has been extended to solve → Navier-Stokes equations, time dependent problems and more. Several AMR techniques have been developed and applied to compressible flow fields to capture characteristics at the strong gradient or discontinuous regions requiring higher space resolution, such as regions involving → shock waves, vortices (→ vortex), and → wakes (see, e.g., Qingluan Xue, "Development of Adaptive Mesh Refinement Scheme and Conjugate Heat Transfer Model for Engine Simulations" (2009), Iowa State Univ., Graduate Theses and Dissertations, Paper 10678).
See also → Smoothed Particle Hydrodynamics.

adaptive; → mesh; → refinement.
