Some Vistas of Astronomical Discovery

As is the case with all epochs, the present one has its own characteristics—both in its political and in its scientific aspects. The science of 1960 is not the science of 1920 ; and, most emphatically, the astronomy of 1960 is not the astronomy of 1920. The differences are not entirely differences in instrumentation and in techniques ; even if the instruments of the 1950’s had been identical wi...

Some Recent Advances in Multigrid Methods 1

Some recent works on multi-parameter Hardy space theory and discrete Littlewood-Paley Analysis

The main purpose of this paper is to briefly review the earlier works of multiparameter Hardy space theory and boundedness of singular integral operators on such spaces defined on product of Euclidean spaces, and to describe some recent developments in this direction. These recent works include discrete multiparameter Calderón reproducing formulas and Littlewood-Paley theory in the framework of...

Vision Modelling in Astronomy : Recent Results 1 Artiicial Vision and Astronomical Images

Many researches were carried on the automated identiication of the astrophysical sources, and their relevant measurements. Large astronomical images may contain typically a large set of stars and diiuse objects. The automated analysis requires sequence of algorithms, for detecting, for identifying and for measuring these sources. Many vision models have been developed for this task. Their use d...
