System behaviors are traditionally evaluated through binary classifications of correctness, which do not suffice for properties involving quantitative aspects of systems and executions. Quantitative automata offer a more nuanced approach, mapping ...$\mathsf{}$$\mathsf{}$$\mathsf{}$$\mathsf{}$$\mathsf{}$$\mathsf{}$

Formal approaches to software analysis and development tend to focus on greenfield scenarios or to look at some piece of given software as a static object. Dynamic evolution of software is a much more common and relevant issue, and its importance ...

Formal methods based on formal logical or mathematical symbolic techniques provide the highest standards to analyse and ensure safety and security properties of cyber-physical systems—but require a large overhead to specify and especially to ...

The Digital Twin (DT) term is currently used, sometimes as a buzzword, to refer to a virtual representation or digital replica of a physical object, process, or system. DTs have the potential to improve efficiency, reduce costs, and enhance ...

Digital twin technology has emerged as a powerful paradigm for modelling, simulating, and managing complex systems virtually across their lifecycle. However, as digitalisation efforts grow exponentially and the endeavours to digitise more objects ...

“In Silico” research drives the world around us, as illustrated by the way our society handles climate change, controls the COVID-19 pandemic and governs economic growth. Unfortunately, the code embedded in the underlying data processing is mostly ...

Code clones are a well-known software quality metric with existing tools for detection and (semi-) automated elimination for common programming languages. While they are usually eliminated by extracting duplicate code into shared methods/functions,...

Traditionally, many embedded systems are considered to be safety-critical, as they are used in cars, airplanes, or power plants. As embedded systems are more and more connected to the internet, they are becoming increasingly security-critical as ...

We propose an approach to using run-time monitoring for the re-engineering of distributed systems. Our re-engineering method MBRE consists of five steps that provide guidance during a re-engineering. By utilizing run-time monitors that are ...

During the past decade, researchers have investigated X-by-Construction (XbC), encompassing extensions beyond correctness concerns as in the more traditional Correctness-by-Construction (CbC) paradigm. Like CbC, XbC is a refinement approach to ...

This perspective piece calls for the study of the new field of Intersymbolic AI, by which we mean the combination of symbolic AI, whose building blocks have inherent significance/meaning, with subsymbolic AI, whose entirety creates significance/...

In recent years, the impact of machine learning (ML) and artificial intelligence (AI) in society has been absolutely remarkable. This impact is expected to continue in the foreseeable future. However, the adoption of AI/ML is also a cause of grave ...

We present the design of a meta-programming system for hybrid AI, integrating spatial model checking and machine learning. The proposed system architecture blends together different programming languages and execution technologies using a ...

In recent years, research on artificial intelligence (AI) has made great progress. AI-tools are getting better in simulating human reasoning and behavior every day. In this paper, we discuss the extent to which AI-tools can support Correctness-by-...

Recent investigations hint at the ability of large language models (LLMs) to generate formal specifications for given program code. In this work, we systematically discuss and categorize different use cases and application scenarios that combine ...

As artificial intelligence (AI) systems influence ever more high-stake decision-making processes, such as university applicant screening or medical diagnoses, ensuring the trustworthiness of these systems and their decisions is crucial. This paper ...

Reactive synthesis is used to automatically generate circuits or programs from temporal logic specifications. In propositional reactive synthesis, generalized reactivity(1) (GR(1)) has proven to be a good compromise between expressiveness and ...

Security by construction is an approach to system development where security considerations are integrated into the design process from the very beginning. Threat modeling helps identify potential threats and vulnerabilities early in the system ...

The development of accurate, reliable and effective FDIR (Fault Detection, Identification and Recovery) components is essential in several application domains, to meet the dependability constraints and to accomplish the higher degree of autonomy ...
