- The objective of this study was to compare the development of sleepiness during manual driving versus level 2 partially automated driving, when driving on a motorway in Sweden. The hypothesis was that partially auto-mated driving will lead to higher levels of fatigue due to underload. Eighty-nine drivers were included in the study using a 2 ? 2 design with the conditions manual versus partially automated driving and daytime (full sleep) versus night-time (sleep deprived). The results showed that night-time driving led to markedly increased levels of sleepiness in terms of subjective sleepiness ratings, blink durations, PERCLOS, pupil diameter and heart rate. Partially automated driving led to slightly higher subjective sleepiness ratings, longer blink durations, decreased pupil diameter, slower heart rate, and higher EEG alpha and theta activity. However, elevated levels of sleepiness mainly arose from the night-time drives when the sleep pressure was high. During daytime, when the drivers were alert, partially automated driving had little or no detrimental effects on driver fatigue. Whether the negative effects of increased sleepiness during partially automated driving can be compensated by the positive effects of lateral and longitudinal driving support needs to be investigated in further studies.

- Hours of service regulations govern the working hours of commercial motor vehicle drivers, but these regulations may become more flexible as highly automated vehicles have the potential to afford periods of in-cab rest or even sleep while the vehicle is moving. A prerequisite is robust continuous monitoring of when the driver is resting (to account for reduced time on task) or sleeping (to account for the reduced physiological drive to sleep). The overall aims of this paper are to raise a discussion of whether it is possible to obtain successful rest during automated driving, and to present initial work on a hypothetical data driven algorithm aimed to estimate if it is possible to gain driving time after resting under fully automated driving. The presented algorithm consists of four central components, a heart rate-based relaxation detection algorithm, a camera-based sleep detection algorithm, a fatigue modelling component taking time awake, time of day and time on task into account, and a component that estimates gained driving time. Real-time assessment of driver fitness is complicated, especially when it comes to the recuperative value of in-cab sleep and rest, as it depends on sleep quality, time of day, homeostatic sleep pressure and on the activities that are carried out while resting. The monotony that characterizes for long-haul truck driving is clearly interrupted for a while, but the long-term consequences of extended driving times, including user acceptance of the key stakeholders, requires further research.

Garden of Earthly Delights

Konstnärligt arbete (övrigt vetenskapligt/konstnärligt)abstract
- Garden of Earthly Delights is a performative installation invading today's holy grail of delight: the club. It is a place for pollination, for reflection, for social interaction, for celebration, for life - growth, decay, composting, death, rebirth, intertanglement and interweaving. For the unknown and for play. We have created a way of working, a way of play that welcomes and interrogates lusts and perversions. This play works as a hospice or container for different dualities and contradictions; naturalness and artificiality, utopia and dystopia, pleasure and decay, harmony and chaos, eros and perversion. It is a play where the rules are constantly emerging, breaking, re-imagining, shuttering, reshaping and dissolving. It is a prolonged threshold swinging in ambiguity and disorientation. It is rigid dissolution, fluidness and malleability. It is the intersection between heaven and hell. We warmly welcome you to take part of this paradise of pleasures, of earthly delights. The piece is a collaboration between 4 FLOORS OF WHORES and the Swedish artist Anders Carlsson. It is a sisterwork to the coming piece V - eller när barnen tar makten, which premieres at Teater Viirus spring 2023. The project is funded by Svenska Kulturfonden, Konstsamfundet & Eugène, Elisabeth och Birgit Nygréns stiftelse. Special thanks to Teater Institutet & Markus Öhrn, Oxi Koskelainen, the staff of Post Bar and Kuutti.

Perspectives on sustainability in Sweden : stuck between two paradigms?

Bokkapitel (refereegranskat)abstract
- In this chapter we take a look at some, primarily, environmental sustainability issues in Sweden. Sweden is in many aspects a rich country with high social and economic welfare and it usually comes out as a country that has handled environmental challenges well. However, from a consumption perspective, Swedish consumers are among the world leaders when it comes to metrics such as ecological footprint and carbon dioxide emissions per capita. By using two paradigmatic views, the Dominant Social Paradigm (DSP) and the New Ecological Paradigm (NEP) we analyze sustainability in Sweden with a particular focus on energy use. We look at sustainability in the three broad areas of policies, corporate activities and consumption and in these areas we delve deeper into environmental sustainability issues concerning recycling and waste, energy efficiency, circular business models, sustainable consumer behaviors in relation to cars and transport, and responsible investments. We end the chapter by discussing implications for the future and the analytical framework and by developing a middle ground which we call ambiguous wavering.

HAnS: IDE-based editing support for embedded feature annotations
- 2021
-
Ingår i: ACM International Conference Proceeding Series. - New York, NY, USA : ACM. ; Part F171625-B, s. 28-31

Konferensbidrag (refereegranskat)abstract
- When developers maintain or evolve software, they often need to know the locations of features. This proves challenging when the feature locations are not documented, when the code was written by different developers who may have left the organization, or when the developer's memory of the implementation has faded. Automated feature location techniques are hard to adopt in practice, especially since they boast too many false positives. To address these challenges, embedded feature annotations have been proposed to allow developers to trace features in code during development with minimal effort. However, tool support is needed for developers to effectively record and use these annotations. We propose HAnS as a tool to meet this need; it is implemented as an IntelliJ IDE plugin to support developers seamlessly record feature locations while they write their code. HAnS supports developers when mapping features to software assets, such as files and code fragments, with code completion and syntax highlighting. It also provides functionality to browse feature definitions and locations, as well as refactor features. A demo video is available at https://youtu.be/cx_-ZshHLgA.
