The field of digital twins and dependability in defence and computing systems is moving towards increased integration and application of digital twin technologies, with a focus on enhancing operational performance, predictive capabilities, and system uptime. Researchers are exploring novel characterization frameworks to standardize and unify the application of digital twins across different domains, facilitating interoperability and robust frameworks. In the area of dependability, new fault-injection frameworks are being developed to overcome limitations of existing frameworks, enabling more precise fault modeling and controllability. Symbolic execution techniques are also being advanced, with new taxonomies and strategies being proposed to combat path explosion and enable practical application on complex software systems. Noteworthy papers include: Nail, a Chisel-based open-source fault injection framework that introduces state-based faults for greater controllability. The paper on symbolic execution in practice, which introduces a systematic taxonomy of strategies to enable symbolic execution on complex software systems.
