6 definitions found From Webster's Revised Unabridged Dictionary (1913) [web1913]: 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 perh. a different word and akin to L. lucere to be light or clear, to shine. See {Lucid}, and cf {Illustrious}, {Lustrum}.] 1. Brilliancy; splendor; brightness; glitter. The right mark and very true luster of the diamond. --Sir T. More The scorching sun was mounted high, In all its luster, to the noonday sky. --Addison. 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 2. Renown; splendor; distinction; glory. His ancestors continued about four hundred years, rather without obscurity than with any great luster. --Sir H. Wotton. 3. A candlestick, chandelier, girandole, or the like generally of an ornamental character. --Pope. 4. (Min.) The appearance of the surface of a mineral as affected by or dependent upon peculiarities of its reflecting qualities. Note: The principal kinds of luster recognized are: metallic, adamantine, vitreous, resinous, greasy, pearly, and silky. With respect to intensity, luster is characterized as splendent, shining, glistening, glimmering, and dull. 5. A substance which imparts luster to a surface, as plumbago and some of the glazes. 6. A fabric of wool and cotton with a lustrous surface, -- used for women's dresses. {Luster ware}, earthenware decorated by applying to the glazing metallic oxides, which acquire brilliancy in the process of baking. From Webster's Revised Unabridged Dictionary (1913) [web1913]: Luster \Lus"ter\, Lustre \Lus"tre\, v. t. [imp. & p. p. {Lustred}; p. pr & vb n. {Lustering}, or {Lustring}.] To make lustrous. [R. & Poetic] Flooded and lustered with her loosened gold. --Lowell. From Webster's Revised Unabridged Dictionary (1913) [web1913]: Lustre \Lus"tre\, n. Same as {Luster}. From WordNet r 1.6 [wn]: lustre n 1: a surface coating for ceramics or porcelain [syn: {luster}] 2: a quality that outshines the usual [syn: {luster}, {brilliancy}, {splendor}, {splendour}] 3: the visual property of something that shines with reflected light [syn: {shininess}, {sheen}, {luster}] From U.S. Gazetteer (1990) [gazetteer]: Lustre, MT Zip code(s): 59225 From The Free On-line Dictionary of Computing (13 Mar 01) [foldoc]: 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.
