Convexity theory and duality theory are important issues in math- ematical programming. Within the framework of credibility theory, this paper rst introduces the concept of convex fuzzy variables and some basic criteria. Furthermore, a convexity theorem for fuzzy chance constrained programming is proved by adding some convexity conditions on the objective and constraint functions. Finally,...

ALTHOUGH none of the work done by the eighteenth-century scientists forms a direct link with anaesthesia, yet knowledge of any kind is bound to influence the future. The discovery of gases in the second half of the century was not only of profound consequence to chemistry, but also to medicine and the world. In order to understand how the discovery of anaesthesia is placed in history, it is nec...
