A systematic approach to the alloy designing problem, which is one of the typical ill-structur-ed problems considered to be solvable only by inspirations of a genius metallurgist, is discussed with respect to the heuristic approach. The procedure to design an alloy of required properties consists of two parts;searching of a starting point(a root) and constructing a tree in order to improve the ...

Conference management is a critical component of a collaborative engineering eeort. This paper describes, CAIRO (Collaborative Agent Interaction and synchROnization system), a system for managing participants in a distributed conference. We have drawn from various models of group interaction and social communications theory in order to develop CAIRO. While most conference systems have focused o...

In this paper we present diierent approaches to structur-ing covariance matrices within statistical classiiers. This is motivated by the fact that the use of full covariance matrices is infeasible in many applications. On the one hand, this is due to the high number of model parameters that have to be estimated, on the other hand the computational complexity of a classiier based on full covaria...

The language Grace is being proposed for specifying and programming in a graph-centered environment based on graph transformation. Emphasis in the design of Grace is laid on modular structur-ing of programs. In this paper we present a simple kind of modules for the language which encapsulate rules and graph transformation units, and export some of them. The local transformation units deene comp...
