Self-awareness in autonomous automotive systems

Self-awareness has been used in many research fields in order to add autonomy to computing systems. In automotive systems, we face several system layers that must be enriched with self-awareness to build truly autonomous vehicles. This includes functional aspects like autonomous driving itself, its integration on the hardware/software platform, and among others dependability, real-time, and security aspects. However, self-awareness mechanisms of all layers must be considered in combination in order to build a coherent vehicle self-awareness that does not cause conflicting decisions or even catastrophic effects. In this paper, we summarize current approaches for establishing self-awareness on those layers and elaborate why self-awareness needs to be addressed as a cross-layer problem, which we illustrate by practical examples

MOSAiC Extended Acknowledgement

For years, the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI), together with the international MOSAiC partners, had been planning and developing the scientific, logistical and financial concept for the implementation of the MOSAiC expedition. The planning and organization of this endeavor was an enormous e˙ort, involving more than 80 institutions from 20 countries. The number of groups and individuals that significantly contributed to the success of the drift observatory goes far beyond the scope of usual polar expeditions

Overview of the MOSAiC expedition - Atmosphere

With the Arctic rapidly changing, the needs to observe, understand, and model the changes are essential. To support these needs, an annual cycle of observations of atmospheric properties, processes, and interactions were made while drifting with the sea ice across the central Arctic during the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition from October 2019 to September 2020. An international team designed and implemented the comprehensive program to document and characterize all aspects of the Arctic atmospheric system in unprecedented detail, using a variety of approaches, and across multiple scales. These measurements were coordinated with other observational teams to explore cross-cutting and coupled interactions with the Arctic Ocean, sea ice, and ecosystem through a variety of physical and biogeochemical processes. This overview outlines the breadth and complexity of the atmospheric research program, which was organized into 4 subgroups: atmospheric state, clouds and precipitation, gases and aerosols, and energy budgets. Atmospheric variability over the annual cycle revealed important influences from a persistent large-scale winter circulation pattern, leading to some storms with pressure and winds that were outside the interquartile range of past conditions suggested by long-term reanalysis. Similarly, the MOSAiC location was warmer and wetter in summer than the reanalysis climatology, in part due to its close proximity to the sea ice edge. The comprehensiveness of the observational program for characterizing and analyzing atmospheric phenomena is demonstrated via a winter case study examining air mass transitions and a summer case study examining vertical atmospheric evolution. Overall, the MOSAiC atmospheric program successfully met its objectives and was the most comprehensive atmospheric measurement program to date conducted over the Arctic sea ice. The obtained data will support a broad range of coupled-system scientific research and provide an important foundation for advancing multiscale modeling capabilities in the Arctic

The battle for hearts and minds? Evolutions in organisational approaches to environmental risk communication

In recent years there has been a great deal of discussion on the potential for a shift away from modernistic or technocratic approaches to decision-making on risk towards more open, inclusive and deliberative approaches. This paper adopts an approach which analyses not the social but the private costs and benefits of such a transition, and the influence that various institutional factors such as the presence of trust amongst stakeholders can have on these. With these factors in mind, the paper considers the reasons why some organisations have taken the first step in this transition by exploring the potential of what the paper terms more communicative approaches to environmental risk management. It then goes on to evaluate the early experiences with such approaches. The analysis finds that at the organisational level the pros and cons of opening up and engaging are quite finely balanced. For the organisations surveyed, the nature of their activities, the significance of formative events and the failure of more traditional forms of risk communication impelled them to experiment with new approaches to risk communication. Such experiments had mixed effects - in some contexts they enhanced the legitimacy of the organisations and built trust amongst stakeholders, whilst in others they did the opposite. The paper concludes by suggesting that in the long run a broader opening up of decision-making processes may result in what might be termed a reverse Phyrric victory: in some cases battles will be lost, but in the long run the war will be won
