The open and broadcast nature of wireless mediums introduces significant security vulnerabilities, making authentication a critical concern in wireless networks.

In recent years, Physical-Layer Authentication (PLA) techniques have garnered considerable ...

Appropriateness of models through modelling languages, tools, and methods is at the core of systems modelling. A concrete example is that useful abstraction depends on the contextual case of modelling purpose and need. Naturally, this results in ...

Systems Engineering (SE) is often visualised through distinct development stages. The first stages started in development relate to the system requirements with several sub-activities related to gathering, defining, and evaluating requirements. A ...

Sustainability has become a key characteristic of modern systems. Unfortunately, the convoluted nature of sustainability limits its understanding and hinders the design of sustainable systems. Thus, cooperation among a diverse set of stakeholders is ...

In this paper we propose an extension to the MagicGrid framework to support virtual prototyping for early system performance Validation & Verification (V&V). Model-Based Systems Engineering (MBSE) is at a maturity where V&V of system performance is ...

Security risk assessment is an important task in systems engineering. It is used to derive security requirements for a secure system design and to evaluate design alternatives as well as vulnerabilities. Security risk assessment is also a complex and ...

Although commonly used in industry, a major drawback of Stateflow is that it lacks support for stochastic properties; properties that are often needed to build accurate models of real-world systems. In order to solve this problem, as the first ...

Trends such as the Internet of Things lead to a growing number of networked devices and to a variety of communication systems. Adding self-adaptive capabilities to these communication systems is one approach to reducing administrative effort and coping ...

We present a novel model-based algorithm, Cooperative Prioritized Sweeping, for sample-efficient learning in large multi-agent Markov decision processes. Our approach leverages domain knowledge about the structure of the problem in the form of a dynamic ...

On the way towards autonomous driving, a steadily increasing number of Advanced Driver Assistance Systems leads to a tremendous test effort to approve their safe operation. However, route-based real-world tests cannot cover this effort sufficiently ...

Abstract Most modern steganographic schemes embed secrets by minimizing the total expected cost of modifications. However, costs are usually computed using heuristics and cannot be directly linked to statistical detectability. Moreover, as previously ...

Mobile devices have limited resources, including memory and processing speed. The performance of mobile applications is an important concern. There are a large number of mobile platforms available with varying operating systems and hardware. ...

This paper proposes an automated model‐based approach for performance test generation for native application variants at unit‐level that specifically focuses on the evaluation of mobile device processing, memory, and battery consumption. The contributions ...

The measurement of autonomic nerve activity plays an important role in the diagnosis and treatment of various cardiovascular diseases. This paper presents a model-based method for measuring autonomic nerve activity and sensitivity. By non-invasively ...

Instructional and support information are very useful in learning and automation stages of skill acquisition. The spatial integration of information is fundamental to reduce in trainees the external cognitive processing. Non-integrated information ...

The search for interpretable reinforcement learning policies is of high academic and industrial interest. Especially for industrial systems, domain experts are more likely to deploy autonomously learned controllers if they are understandable and ...

Systems-of-Systems (SoS) have demanded for novel solutions to deal with their large-scale, dynamic, and critical nature. Then, software engineering and simulation communities have been motivated to develop solutions to engineering such systems. In this ...

Under the premise that model-centric engineering enterprises of the future will necessitate specialized competencies and leadership, ongoing research is investigating both model curation as a practice and model curator as a new leadership role. ...

Software has been increasingly embedded into systems (e.g., autonomous cars, traffic control systems, power distribution systems) to increase the precision of their functionalities, deliver automation, and make them smarter. Those systems have been ...

The definition of a Reference Architecture for Space Systems is a noteworthy field to improve the development of embedded critical systems. The European Space Agency (ESA) and the European Commission (EU) are actively working on different initiatives to ...

Designing a robotic application is a challenging task. It requires a vertical expertise spanning various fields, starting from hardware and low-level communication to high-level architectural solution for distributed applications. Today a single expert ...
