To enhance reusability in the field of simulation, model bases must be equipped with powerful tools for retrieval, modification and aggregation of simulation models. In this paper, the role of database management systems supporting a modeling environment is discussed and reuse oriented query interfaces are presented. Specifically, we advocate a graph browser operating on a semantic network of reusable components.

The design of a prototype knowledge-based system for crystal structure determination is described. This system provides a framework which integrates the direct methods probabilistic strategies for solving crystal structures and databases of over 90000 fully determined crystal structures. At the core of the system is the concept of imagery, that is, the ability to construct and reason about images in creative and unique ways. The process of determining the structure of a crystal is likened to an iterative scene analysis, which draws from the long-term memory of structural motifs and the application of chemical and crystallographic rules. Taken individually, such analyses result in the recognition and comprehension of a specific chemical scene. Put together they provide insight into the three-dimensional grammar of chemistry and the rules of molecular recognition.< >

The case is made in this paper for encouraging the scientist to become familiar with architectural features of the. supercomputer in use. This is essential for a proper choice of an efficient computational procedure for a given problem, as demonstrated by matching two vectorized algorithms to the CDC CYBER 205 and its special features. The two problems reported here are the Monte Carlo method for lattice gauge theory calculations and the multigrid method for partial differential equation solvers, combined with the description of the relevant aspects of the CDC CYBER 205 architecture.

A Workshop in Two Year College Programs in Computer science was held August 11-13, 1975 in Gloucester Point, Virginia. Sponsored by the ACM's Special Interest Group in Computer science Education (SIGCSE), it brought thirteen community and junior college participants together at the Virginia Institute for Marine science (VIMS) to work toward recommendations for a two year program.
