- Safety-critical systems are subject to rigorous assurance and certification processes to guarantee that they do not pose unreasonable risks to people, property, or the environment. The associated activities are usually complex and time-consuming, thus they need adequate support for their execution. The activities are further becoming more challenging as the systems are evolving towards open, interconnected systems with new features, e.g. Internet connectivity, and new assurance needs, e.g. compliance with several assurance standards for different dependability attributes. This requires the development of novel approaches for cost-effective assurance and certification. With the overall goal of lowering assurance and certification costs in face of rapidly changing features and market needs, the AMASS project has created and consolidated the de-facto European-wide open solution for assurance and certification of critical systems. This has been achieved by establishing a novel holistic and reuse-oriented approach for architecture-driven assurance, multi-concern assurance, and for seamless interoperability between assurance and engineering activities along with third-party activities. This paper introduces the main elements of the AMASS approach and how to use them and benefit from them.

Tidskriftsartikel (refereegranskat)abstract
- In this paper, we analyze the performance of a positioning system based on the fusion of Ultra-Wideband (UWB) ranging estimates together with odometry and inertial data from the vehicle. For carrying out this data fusion, an Extended Kalman Filter (EKF) has been used. Furthermore, a post-processing algorithm has been designed to remove the Non Line-Of-Sight (NLOS) UWB ranging estimates to further improve the accuracy of the proposed solution. This solution has been tested using both a simulated environment and a real environment. This research work is in the scope of the PRoPART European Project. The different real tests have been performed on the AstaZero proving ground using a Radio Control car (RC car) developed by RISE (Research Institutes of Sweden) as testing platform. Thus, a real time positioning solution has been achieved complying with the accuracy requirements for the PRoPART use case. © 2020 by the authors.

Introduction and progress in the EMPIR project TracePQM : Traceability Routes for Electric Power Quality Measurements
- 2018
-
Ingår i: Journal of Physics. - : Institute of Physics Publishing.

Konferensbidrag (refereegranskat)abstract
- Increasing demands for traceable, accurate measurements of power and power quality (PQ) parameters have resulted in an intensive metrology research effort in this area. This paper describes the objectives and so far achieved results of the EURAMET EMPIR Project TracePQM (15RPT04), jointly founded by the European Union and the participating countries. The overall goal of this project is to develop an open, modular, and well documented metrology grade system for measurement of power and PQ parameters by means of digital sampling techniques available to everyone and to increase research capacity in this area.
