In safety-critical systems, certain safety constraints must be satisfied before an operation can be performed. Such constraints typically depend on the state of the system at the ...
We have developed and successfully applied a technique to build a high integrity compiler from Pasp, a Pascal-like language, to Asp, the target language for a high integrity proce...
An important practical problem in fault diagnosis is discriminating between permanent faults and transient faults. In many computer systems, the majority of errors are due to tran...

Independence is a fundamental requirement for calculating system reliability from component reliabilities, whether in hardware or software systems. Markov analysis is often used i...
Fault trees provide a graphical and logical framework for analyzing the reliability of systems. A fault tree provides a conceptually simple modeling framework to represent the sys...

Residual defects is one of the most important factors that allow one to decide if a piece of software is ready to be released. In theory, one can find all the defects and count th...
: A middleware architecture named ROAFTS (Real-time Object-oriented Adaptive Fault Tolerance Support) is presented. ROAFTS is designed to support adaptive fault-tolerant execution ...
A well-known security problem with MPOA is that cutthrough connections generally bypasses firewall routers if there are any. None of the previously proposed approaches solved the ...
Engineers use software tools to analyze designs for critical systems. Because important decisions are based on tool results, tools must provide valid modeling constructs; engineer...
