Design of Observer-based Controllers,rresponding volume is expected to be published soon. Histograms in visual magnitudes and plots of the galactic distribution are presented here for some of the groups under discussion during the colloquium.

Spectral Classification and the Relations Between Peculiar Giantse spectra we examine the more evident it becomes that the groups that we are talking about here are practically never discrete and clearly bounded. There always seem to be marginal stars that blur the distinctions between the so-called groups.

Spectrophotometry Characteristics of Barium StarsThese stars with enhanced Ba II at 4554A are otherwise generality similar to late-type giant stars. The majority of them were identified in an objective-prism survey by MacConnell et al. (1972). They listed 150 “certain” and 90 “marginal” Ba stars but made no further estimates of barium intensity. A
