discrete gosasté, jodâ (#) Fr.: discret Apart or detached from others; separate; distinct. Composed of distinct or discontinuous elements. From O.Fr. discret, from L. discretus "separated, distinct," from p.p. of discernere "to distinguish," from → dis- "off, away" + cernere "distinguish, separate, sift," → crisis. Gosasté "broken, broken off," p.p. of gosastan "to break, split,"
Mid.Pers. wisistan "to break, split," Av. saed- "to split,"
asista- "unsplit, unharmed," Skt. chid- "to split, break, cut off,"
Gk. skhizein "to split," L. scindere "to split;"
PIE stem *skei- "to split, cut." |
discrete absorption component (DAC) hamne-ye daršami-ye gosasté Fr.: composante d'absorption discrète The rapid, systematic changes in the absorption parts of the → P Cygni profiles of the ultraviolet → resonance lines (Si IV, C IV, and N V) observed in a majority of massive → hot stars. DACs are typically seen to accelerate to the → blue wing of the profile over a few days, becoming narrower as they approach the → terminal velocity. → discrete; → absorption; → component. |
discrete data dâdehâ-ye gosasté (#) Fr.: données discrètes Data that can only take a small set of particular values, usually whole numbers. For instance, number of children in a family cannot be 2.4, since parents cannot actually have 2.4 children. → continuous data. |
discrete radio source xan-e râdioyi-ye jodâ Fr.: radiosource discrète A localized source on the celestial sphere that can be observationally separated at radio wavelengths from its background emission. |
discrete spectrum binâb-e gosasté Fr.: spectre discret A spectrum in which the component wavelengths (and wave numbers and frequencies) constitute a discrete sequence of values (finite or infinite in number) rather than a continuum of values. |
discrete transition gozareš-e gosasté Fr.: transition discrète A transition between two quantum-mechanical energy levels. See also → discrete spectrum. → discrete; → transition. |
discrete value arzeš-e gosasté Fr.: valeur discrète A quantity that has certain magnitudes and does not represent a → continuous variable. |
discrete variable vartande-ye gosasté Fr.: variable discret A variable which has only → discrete values and has no in-between values. |
discrete-time quantum walk puyeš-e kuântomi bâ zamân-e gosasté Fr.: marche quantique à temps discret A → quantum walk involving a probabilistic → operator that changes the direction while leaving the position fixed, and a shift operator that changes the position. Discrete-time quantum walk was introduced by J. Watrous (2001, Journal of Computer and System Sciences 62, 376) |
