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...

The Answer Garden supports knowledge sharing in two intertwined ways: by making relevant information retrievable and by mediating access to people with knowledge. We present a case study in which the Answer Garden approach was applied to encourage knowledge sharing in maintenance engineering of a steel mill. The results show that the sheer amount of drawings and the long history of changing cla...

according to philosophers, the soul is an immaterial essence that can be perfected by knowledge and action. but how does the soul perfect through knowledge and action? what is the way of perfection? furthermore, is such perfection stopped by death or does its life continue after death? in this paper, i will explain avicenna’s answers to these questions. also, i will examine the problem of the p...
