At the time of this report in September 1993, about a year before the next General Assembly in 1994, the membership of Commission 42 stands at 357, an increase of forty-two members since the time of the last report prepared in September 1990. This is an increase of more than 10 percent, indicating the continuing vitality of our Commission in ...

Besides the two primary operations of erosion and dilation, there are two secondary operations that play key roles in morphological image processing, these being opening and its dual, closing. We focus mostly on opening, the properties of closing usually being analogous via complementation.

The evolution of a star depends primarily on its mass, chemical composition, so it is important to know the distribution of stellar masses when the stars are born. Stars can be born as singles, in pairs, or in multiple systems. A large fraction of the stars belongs to binary systems.

The structure of close binaries
Astrophysics and Space Science, 1978A method for calculating the structure of a close binary component is presented. It is seen that the effect of binary distortion is to shift the zero age main sequence to the right. Attempts to construct contact systems with these models confirm the results of earlier workers that this is not possible.

In the second chapter of this volume we have investigated the ways in which axial rotation, or the proximity of another star, will influence the equilibrium figures of the components of close binary systems; and in subsequent two chapters we extended our investigation to consider the effects of dynamical tides, or of nonuniform rotation. The aim of the

Research on close binary systems has continued at a high level during the past triennium, although the rate of growth is noticeably slower - probably reflecting the cutbacks in funds to which many of us are subject. There have also been changes of emphasis within the field, which are commented on in the pages that follow.
