Laser à exciplexe KrF impulsionnel de grande énergie

Fast - Discharge - Initiated KrF Laser

Intense laser emission has been observed from the KrF molecule formed by a chemical reaction initiated by fast-discharge circuitry. With a gas mixture of He:Kr:NF, = 500:50:1 and a sample pressure of 700 Torr, an output energy of 0. 8 mj was measured from a 25-nsec laser pulse (FWHM). Spectral analysis of the laser emission indicated laser action at 248.5 and 249.5 nm.

L'interaction au service de l'optimisation à grande échelle des entrepôts de données relationnels

The database technology is an adequate environment for the interaction. It may concern severalcomponents of the DBMS: (a) the data, (b) the queries, (c) the optimization techniques and (d) the devices. Atthe data level, correlations between attributes are extremely common in the real world relational data, and havebeen exploited to define materialized views and indexes. At the query...
