In order to provide an alternative way for accessing WWW, we propose a FaxWeb system to access WWW services using a fax machine in this paper. Based on the FaxWeb system, users, who do not have computers or who do not have the capability of using computers, can access WWW services using fax machines. In this way, people can adopt not only computers but also fax machines, which belong to the tra...

In this paper, we propose a framework to study reenement of abstract machines in the B-method. It allows us to properly deal with shared variables, possibly introduced by composition primitives sees and imports. We exhibit local conditions on components which are suucient to ensure global correctness of a software system. Finally, we show how restrictions on the architecture of software systems...
