Runtime monitors have been proposed as a means to increase the reliability of safety-critical
systems. In particular, this report addresses runtime monitors for distributed hard real-time …

Dependability properties of bi-directional and braided rings are well recognized in improving
communication availability. However, current ring-based topologies have no mechanisms …

Critical real-time systems like spacecraft and aircraft commonly use Byzantine fault-tolerant
(BFT) state machine replication (SMR) to mask faulty processors and sensors. Unfortunately …

Data analytics applied to nuclear power operations and nuclear safeguards is in a nascent

This paper presents Crux, a new permissionless blockchain consensus algorithm that
achieves higher fault tolerance rate with more flexibility than existing blockchains such as …

Low-cost fault-tolerant systems design presents a continual trade-off between improving
fault-tolerant properties and accommodating cost constraints. With limited hardware options …

This work presents a failure data analysis campaign on Bluetooth personal area networks
(PANs) conducted on two kind of heterogeneous testbeds (working for more than one year) …

A safety-critical system needs fault-tolerant communication between its components. This is
especially important for automotive domain, as it consists of distributed real-time systems …
