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.

Luster is produced by direct application of very thin layer of metallic paint on the surface of glazed ceramic which after firing at temperatures between 500 to 600oC in a reducing atmosphere results in the formation of a metallic like layer (Perez et al.
Luster is a decorative finish in which drawings and patterns applied on the surface of medieval luxury tin-glazed pottery shows a coppery golden and silver-like metallic shine.
