In this paper two external schema generation algorithms are presented. These algorithms are defined in the framework of the new external schema definition methodology for OODBs put forward in (Samos, 1995); they generate an external schema from a set of classes selected from those existing in an external schema definition repository. Their main characteristic is that they avoid the generation o...

In this research, we consider an application of the Bayesian Inferences in machine replacement problem. The application is concerned with the time to replace two machines producing a specific product; each machine doing a special operation on the product when there are manufacturing defects because of failures. A common practice for this kind of problem is to fit a single distribution to the co...

One of the areas in which fire hazard assessment techniques have been applied within regulation is for transportation vehicles. In particular, commercial aviation and passenger rail have utilized fire hazard assessment as a means to achieve safety goals well before these techniques became common in buildings. This chapter will review the methods employed and the recent evolution of predictive t...
