The intensity of individual penumbral filaments has recently been measured at the Pic-du-Midi Observatory as well as from observations obtained during the third flight of the Soviet Stratospheric Solar Station. We have used the results of these measurements to calculate the corresponding average pen

The mean width and distribution of penumbral filaments of a sunspot have been estimated, using white light photographs obtained with a vacuum, Newtonian type, telescope. Three areas corresponding to the penumbra of a sunspot have been analysed. Data were collected during the solar eclipse of June 19

A model of a sunspot penumbra, including the effects of magnetic field, compressibility, and buoyancy, is studied in order to identify the mode of running penumbral waves. It is found that the penumbral waves may be identified with gravity-modified magneto-acoustic waves of the 'plus' type that are

We propose a framework for studying bottom-up restructuring heuristics for binary search trees. We identify the key role played by depth-reducing rules in obtaining logarithmic amortized cost per access. We show that splaying is by no means the only heuristic that offers logarithmic amortized cost.
