In this paper we suggest a new approach to design of the adaptive network safety control mechanisms. This approach is based on the fuzzy logic theory and allows to formalize both quantitative and qualitative parameters of the network safety system. Also it is suggested an algorithm for design of the model for the adaptive network safety control mechanism with safety functional requirements form...

The integration of safety-relevant software and software developed to normal quality standards in the same embedded system needs a protection mechanism to ensure that the safety-relevant software cannot be adversely affected by failures in the rest the system. The protection mechanism is usually assumed to be provided by the "system software", which implies that the system software must be deve...

safety requirements quality is typically expressed at the software system levels, which may lead to specific safety-related functions that may be applied in either or both hardware and software. According to the Previous work of academia and industry standards such as ISO 25021 square series safety requirements can be defined and measured internally and externally; the internal safety concepts ...

The virtual class 15] construct was rst introduced in the language Beta to provide added expressiveness when used with inheritance. Unfortunately, the virtual class construct in Beta is not statically type-safe. In this paper we show how a generalization of the semantics of object-oriented languages with a MyType construct leads to a variant of virtual classes which needs no run-time checks. Th...
