3. The Collaborative International Dictionary of English v.0.48
Luster \Lus"ter\, Lustre \Lus"tre\, n. [F. lustre; cf. It.
   lustro; both fr. L. lustrare to purify, go about (like the
   priests at the lustral sacrifice), traverse, survey,
   illuminate, fr. lustrum a purificatory sacrifice; perh. akin
   to E. loose. But lustrare to illuminate is perhaps a
   different word, and akin to L. lucere to be light or clear,
   to shine. See Lucid, and cf. Illustrious, Lustrum.]
   [1913 Webster]
   1. Brilliancy; splendor; brightness; glitter.
      [1913 Webster]

                                                  --Sir T. More.

            In all its luster, to the noonday sky. --Addison.
      [1913 Webster]

   Note: There is a tendency to limit the use of luster, in this
         sense, to the brightness of things which do not shine
         with their own light, or at least do not blaze or glow
         with heat. One speaks of the luster of a diamond, or of
         silk, or even of the stars, but not often now of the
         luster of the sun, a coal of fire, or the like.
         [1913 Webster]

                                                  Wotton.

      affected by, or dependent upon, peculiarities of its

         adamantine, vitreous, resinous, greasy, pearly, and
         silky. With respect to intensity, luster is
         characterized as splendent, shining, glistening,

6. The Free On-line Dictionary of Computing (30 December 2018)
LUSTRE

   (A French acronym for Synchronous real-time Lucid).  Real-time
   dataflow language for synchronous systems, especially
   automatic control and signal processing.  A Lucid subset,
   plus timing operators and user-defined clocks.

   Designed for automatic control applications.  It is based on
   the idea that automatic control engineers use to analyse, and
   specify their systems in terms of functions over sequences
   (sampled signals).  It thus seems both safe and cost effective
   to try to compile directly those descriptions into executable
   code.  A lot of work has been done, so as to get efficient
   compilation, and also in formal verification.  The language
   has been used in nuclear plant control, and will be used in
   aircraft control.
