- 2023
-
In: Physics reports. - : Elsevier. - 0370-1573 .- 1873-6270. ; 1023, s. 1-84
-
Research review (peer-reviewed)abstract
- Presently under construction in Lund, Sweden, the European Spallation Source (ESS) will be the world’s brightest neutron source. As such, it has the potential for a particle physics program with a unique reach and which is complementary to that available at other facilities. This paper describes proposed particle physics activities for the ESS. These encompass the exploitation of both the neutrons and neutrinos produced at the ESS for high precision (sensitivity) measurements (searches).

Modeling and Timing Analysis of Vehicle Functions Distributed over Switched Ethernet
- 2017
-
In: IECON 2017 - 43RD ANNUAL CONFERENCE OF THE IEEE INDUSTRIAL ELECTRONICS SOCIETY. - 9781538611272 ; , s. 8419-8424
-
Conference paper (peer-reviewed)abstract
- This paper proposes an approach to model switched Ethernet communication within a model- and component-based software development framework for vehicular distributed embedded systems. The paper also presents a method to extract the network timing model from the systems that use switched Ethernet networks. In order to provide a proof of concept, an existing industrial component model and its tool suite, namely RCM and Rubus-ICE respectively, are extended by implementing the modeling technique, the timing model extraction method and response-time analysis of the Ethernet AVB protocol. The extensions to RCM are backward compatible with the modeling and end-to-end timing analysis of traditional in-vehicle networks and legacy (previously developed) vehicular distributed embedded systems. Furthermore, the paper discusses the implementation and test strategy used in this work. Finally, the usability of the modeling approach and implemented timing analysis is demonstrated by modeling and time analyzing a vehicular application case study with the extended component model and tool suite.

Conference paper (peer-reviewed)abstract
- The automotive E/E architectures are evolving from the traditional distributed architectures to upcoming consolidated domain architectures and possibly future centralised architectures. This paper demonstrates modelling and timing analysis of real-time embedded systems on contemporary automotive E/E architectures using the Rubus-ICE tool suite. The Rubus concept and tool suite, developed and evolved based on close academic-industrial collaboration, have been used in the automotive industry for over 25 years. The paper also demonstrates recent extensions and discusses proposals to support the modelling and timing analysis of the systems on future E/E architectures.

The ESSnuSB Design Study: Overview and Future Prospects
- 2023
-
In: Universe. - : MDPI. - 2218-1997. ; 9:8
-
Research review (peer-reviewed)abstract
- ESSnuSB is a design study for an experiment to measure the CP violation in the leptonic sector at the second neutrino oscillation maximum using a neutrino beam driven by the uniquely powerful ESS linear accelerator. The reduced impact of systematic errors on sensitivity at the second maximum allows for a very precise measurement of the CP violating parameter. This review describes the fundamental advantages of measurement at the second maximum, the necessary upgrades to the ESS linac in order to produce a neutrino beam, the near and far detector complexes, and the expected physics reach of the proposed ESSnuSB experiment, concluding with the near future developments aimed at the project realization.

The European Spallation Source neutrino super-beam conceptual design report
- 2022
-
In: The European Physical Journal Special Topics. - : Springer Nature. - 1951-6355 .- 1951-6401. ; 231:21, s. 3779-3955
-
Research review (peer-reviewed)abstract
- A design study, named ESSνSB for European Spallation Source neutrino Super Beam, has been carried out during the years 2018–2022 of how the 5 MW proton linear accelerator of the European Spallation Source under construction in Lund, Sweden, can be used to produce the world’s most intense long-baseline neutrino beam. The high beam intensity will allow for measuring the neutrino oscillations near the second oscillation maximum at which the CP violation signal is close to three times higher than at the first maximum, where other experiments measure. This will enable CP violation discovery in the leptonic sector for a wider range of values of the CP violating phase δCPδCP and, in particular, a higher precision measurement of δCPδCP. The present Conceptual Design Report describes the results of the design study of the required upgrade of the ESS linac, of the accumulator ring used to compress the linac pulses from 2.86 ms to 1.2 μs, and of the target station, where the 5 MW proton beam is used to produce the intense neutrino beam. It also presents the design of the near detector, which is used to monitor the neutrino beam as well as to measure neutrino cross sections, and of the large underground far detector located 360 km from ESS, where the magnitude of the oscillation appearance of νe from νμ is measured. The physics performance of the ESSνSB research facility has been evaluated demonstrating that after 10 years of data-taking, leptonic CP violation can be detected with more than 5 standard deviation significance over 70% of the range of values that the CP violation phase angle δCPδCP can take and that δCPδCP can be measured with a standard error less than 8° irrespective of the measured value of δCPδCP. These results demonstrate the uniquely high physics performance of the proposed ESSνSBESSνSB research facility.

Provisioning of Deterministic and Non-Deterministic Services for Vehicles: The Rubus Approach
- 2016
-
In: 4th International Workshop on Critical Automotive Applications: Robustness & Safety CARS-2016. - Göteborg, Sweden.
-
Conference paper (peer-reviewed)abstract
- Providing computer-based services for vehicle functions has evolved to the point where a large majority of functions are realized by software. However, the need to provide safety and security in critical functions such as braking, steering, motor control, etc. requires an approach that can guarantee the continuous reliable operation of the functions. At the same time, there are a variety of functions that are less critical from the vehicle operation perspective that can be provided where safety and security are less critical. From a vehicle manufacturers point of view, providing both types of services in an economic and reliable manner is a real challenge. To meet this challenge, we consider the Rubus Tool Suit for the software development and a well-proven (in industrial use for over twenty years) and certified (according to ISO 26262) operating system Kernel for its execution. In addition, a user-friendly approach to model- and component-based development concept called the “software circuits” has provided an approach to meet the demands of both safety-critical deterministic and as well as non-safety critical non-deterministic services. In this paper, a brief history of the evolution of Rubus approach as well as an overview of the driving concepts used in providing the Rubus products are described.

Academic-industrial Collaboration in the Vehicle Software Domain: Experiences and End-user Perspective
- 2016
-
In: 4th International Workshop on Critical Automotive Applications. - Göteborg, Sweden.
-
Conference paper (peer-reviewed)abstract
- In this paper we present a success story of academic-industrial collaboration in the vehicular domain. The collaboration has resulted in the development and evolution of a model- and component-based software development tool chain that is used to develop safety-critical, robust, and certified, control software for vehicles. The tool chain has been successfully used in the vehicle industry for about 20 years. The sustained development of the tool chain is based one a unique collaboration, described in this paper, where the collaborators form a clear value chain from academia, through tool-developer, to the end-users of the technology. We describe experiences of each collaborator with a focus on the end-user's perspective. Moreover, we highlight some ongoing and future works within this collaboration.

End-to-end Timing Analysis of Black-box Models in Legacy Vehicular Distributed Embedded Systems
- 2015
-
In: 21st IEEE International Conference on Embedded and Real-Time Computing Systems and Applications RTCSA'15. - 9781467378550 ; , s. 149-158
-
Conference paper (peer-reviewed)abstract
- A majority of existing techniques and tools, used in the vehicular industry, support the extraction of end-to-end timing models. Such models are used to perform timing analysis of distributed embedded systems at an abstraction level that is close to their implementation. This paper takes a first initiative to provide such a support at a higher level of abstraction. At such a level, the system can be modeled with inter-connected black-box models of nodes whose internal software architectures may not be available. However, most of the design decisions about network communication are available. This represents a typical scenario in the vehicular industry where most of the artifacts are reused from either legacy systems, other projects or previous releases of the vehicle. In this paper we present an approach for the extraction of end-to-end timing models at the highest level of abstraction used in the vehicular domain. Using these models, end-to-end path delay analysis of the systems can be performed at a higher abstraction level and at an early phase during the development. As a proof of concept we implement this technique in an industrial tool suite, Rubus-ICE, that is used for the development of these systems by several international companies. Using the extended tool, we conduct a vehicular-application case study.
