Abstract: A common way of exposing functionality in contemporary systems is by providing a Web-API based on the REST API architectural guidelines. To describe REST APIs, the industry standard is currently OpenAPI-specifications. Test generation and fuzzing methods targeting OpenAPI-described REST APIs have been a very active research area in recent years. An open research challenge is to aid users in better...
Abstract: EAST-ADL is a domain-specific modelling language for the design and analysis of vehicular embedded systems. Seamless modelling through multiple concrete syntaxes for the same language, known as blended modelling, offers enhanced modelling flexibility to boost collaboration, lower modelling time, and maximise the productivity of multiple diverse stakeholders involved in the development of complex s...
Abstract: When a language evolves, meta-models and associated gram- mars need to be co-evolved to stay mutually consistent. Previous work has supported the automated migration of a grammar after changes of the meta-model to retain manual optimizations of the grammar, related to syntax aspects such as keywords, brackets, and component order. Yet, doing so required the manual specification of optimization rul...
Abstract: Many test prioritisation techniques have been proposed in order to improve test effectiveness of Continuous Integration (CI) pipelines. Particularly, diversity-based testing (DBT) has shown promising and competitive results to improve test effectiveness. We report on a case study considering the CI pipeline of Axis Communications in Sweden. We compared three different prioritisation approaches (i....
Abstract: Many test prioritisation techniques have been proposed in order to improve test effectiveness of Continuous Integration (CI) pipelines. Particularly, diversity-based testing (DBT) has shown promising and competitive results to improve test effectiveness. However, the technical and practical challenges of introducing test prioritisation in CI pipelines are rarely discussed, thus hindering the appli...
Abstract: The transport system is currently undergoing a transition to become fossil-free and sustainable. Electrification of vehicles is an important part of this transition. These vehicles must include batteries, whose health status will decrease during their lifetime. Batteries whose status no longer fulfill the requirements for use in vehicles can, however, still have a long remaining life-time if used ...
Abstract: We consider the problem of on-arrival dispatching and scheduling jobs with stochastic execution times, inter-arrival times, and deadlines in multi-server fog and edge computing platforms. In terms of mean response times, it has been shown that size-based scheduling policies, when combined with dispatching policies such as join-shortest-queue, provide better performance over policies such as first-...
Abstract: Older adults are a heterogeneous population for which many e-health innovations are inaccessible. Involving older adults in user-centered design (UCD) with a specific focus on inclusive design is important to make e-health more accessible to this user group. This case study aimed to explore the feasibility of a new UCD approach aiming to minimize bias in the design phase of a digital support for o...
Abstract: In this work, we explore how we can assist engineers in managing, in a lightweight way, both consistency and design uncertainty during the creation and maintenance of models and other development artifacts. We propose annotating degrees of doubt to indicate design uncertainties on elements of development artifacts. To combine multiple opinions, we use the fusion operators of subjective logic. We s...
Abstract: With the rapidly growing use of Multi-Agent Systems (MASs), which can exponentially increase the system complexity, the problem of planning a mission for MASs became more intricate. In some MASs, human operators are still involved in various decision-making processes, including manual mission planning, which can be an ineffective approach for any non-trivial problem. Mission planning and re-planni...
Abstract: Abstract Context Turner syndrome (TS) is a rare genetic syndrome with an increased mortality, mainly attributed to cardiovascular disease. Objective This work aimed to investigate and correlate the lipid profile in adult women with TS to clinical characteristics. Methods A 12-year prospective cohort study, including 4 study visits, was conducted at a specialist hospital. A total of 102 women with ...
Abstract: Intelligent transportation systems face various challenges, including traffic congestion, environmental pollution, and inefficient transportation management. Optimizing routes and schedules for efficient delivery of goods and services can mitigate the aforementioned problems. Many transportation and routing problems can be modeled as variants of the Traveling Salesmen Problem (TSP) depending on th...
Abstract: Climate change is tightly coupled to the usage of energy in different forms. Creating and using sustainable energy solutions is increasingly being recognized as the greatest challenge of our time. The energy crisis concerns everyone who consumes energy or services that rely on energy to be performed, in practice almost everything we buy. However, the temporal and psychological distance to climate ...
Abstract: The integration of the Internet of Things (IoT) and Machine Learning (ML) technologies has opened up for the development of novel types of systems and services. Federated Learning (FL) has enabled the systems to collaboratively train their ML models while preserving the privacy of the data collected by their IoT devices and objects. Several FL frameworks have been developed, however, they do not e...
