Abstract: With the emergence of “Industry 4.0”, the integration of cloud technologies and industrial cyber-physical systems becomes increasingly important to boost productivity. The industrial cyber-physical systems infrastructures and their fusion with the cloud lead to massive amounts of data acquired for controlling particular processes, but also for supporting decision-making. Although cloud-assisted sy...
Abstract: It is known that offsets in general are not sustainable, i.e., if offsets in a system are modified it is not trivial to determine if this affects schedulability or not. In this paper we investigate if there are situations where offsets can be deemed sustainable, i.e., situations where one can safely modify an offset without impairing schedulability. We introduce, for the approximate Response-Time ...
Abstract: Software systems are complicated, and the scientific and engineering methodologies for software development are relatively young. Cyber-physical systems are now in every corner of our lives, and we need robust methods for handling the ever-increasing complexity of their software systems. Model-Driven Development is a promising approach to tackle the complexity of systems through the concept of abs...
Abstract: Purpose: Evaluation of the treatment outcome of using patient-specific implantable scaffolds seeded with autogenous bone marrow mononuclear cell layer containing stem cells and platelet-rich fibrin in the treatment of alveolar cleft defect. Materials and methods: 12 alveolar cleft defects were divided into 2 groups; group A, six alveolar defects were treated using 3D printed patient’s specific imp...
Abstract: The use of multiagent systems (MASs) in real-world applications keeps increasing, and diffuses into new domains, thanks to technological advances, increased acceptance, and demanding productivity requirements. Being able to automate the generation of mission plans for MASs is critical for managing complex missions in realistic settings. In addition, finding the right level of abstraction to repres...

Abstract: Improper Input Validation (IIV) is a dangerous software vulnerability that occurs when a system does not safely handle input data. Although IIV is easy to detect and fix, it still commonly happens in practice; so, why do developers not recognize IIV? Answering this question is key to understand how to support developers in creating secure software systems. In our work, we studied to what extent de...
Abstract: Different tools adopt different terms, metrics, and ways to identify and measure technical debt. We attempt to clarify the situation by comparing the features and popularity of technical debt measurement tools and analyzing the existing empirical evidence on their validity....
Abstract: Multi-Agent Systems (MASs) have been widely adopted in robotics, as a means to solve complex missions by subdividing them into smaller tasks. In such a context, Multi-Robot Task Allocation (MRTA) has been a relevant research area, with the main aim of providing formulations and solutions to different mission configurations, in order to optimize the planning and the execution of complex missions ut...
Abstract: Performance testing with the aim of generating an efficient and effective workload to identify performance issues is challenging. Many of the automated approaches mainly rely on analyzing system models, source code, or extracting the usage pattern of the system during the execution. However, such information and artifacts are not always available. Moreover, all the transactions within a generated ...
Abstract: Adapting in-person learning activities such as labs for online courses presents many challenges for educators and is of particular interest during the COVID-19 pandemic. In this paper, we describe accessibility challenges and solutions in an implementation of lab simulations for an Occupational Health and Safety course. The labs simulate measuring and evaluating workplace noise, light and heat lev...
Abstract: Serious games have become more common in higher education as tools for delivering experiential learning. They are particularly useful during times of crisis like the COVID-19 pandemic, with almost all learning switching to virtual as populations isolate and people learn from home. Creating such games for typical able learners that are also accessible to learners with disabilities can be challengin...
Abstract: The increasing use of embedded systems to provide new functionality and customer experience requires developing the embedded systems carefully. As a new challenge, autonomous systems are developed to be working in a fleet to provide production workflows. Developing such a system-of-systems requires utilizing various software tools to manage the complexity. One task in developing safety-critical pr...
Abstract: The technical evolution enables the development and application of autonomous systems in various domains. In the on-road and off-road vehicle domains, autonomous vehicles are applied in different contexts. Autonomous cars are designed as single system solutions, while in other scenarios, multiple autonomous or semi-autonomous vehicles are integrated into a system-of-systems. We utilize a case from...
