Differential 2.2μm (K-band) luminosity functions are presented for a complete sample of 1570 nearby (Vgsr ≤ 3000 km/s, where Vgsr is the velocity measured with respect to the Galactic standard of rest), bright (K ≤ 10 mag), galaxies segregated by visible morphology. The K-band luminosity function for late-type spirals follows a power law that rises towards low luminosities whereas the K-band lu...

Data warehouse systems integrate data from heterogeneous sources. These sources are autonomous in nature and change independently of a data warehouse. Owing to changes in data sources, the content and the schema of a data warehouse may need to be changed for accurate decision making. Slowly changing dimensions and temporal data warehouses are the available solutions to manage changes in the con...

the streets, take to swimming, take over, Old, Although this ,'tl)proach proves effective in parsing and in generation, there are two acute problems which still require solutions. First, due to the huge size of the phrasal lexicon, cspeciaIly when considering subtle meanings and idiosyncratic behavior of phrases, encoding of ]exical entries cannot be done manually. Thus, phrase acquisition must...

Several studies have shown the feasibility and thermal potential of gypsum plaster with microspheres PCM, but very few them investigated an approach practical standards concern. In this work, different characterizations are performed according to European on a standard two plasters formulated 20 wt.% PCM microspheres. A material is experimentally made by mixing conventional microspheres, wherea...
