  1. 11. Formation of solar bipolar regions : Magnetic flux concentrations from suction of the negative effective magnetic pressure instability

    Författare :Illa Rivero Losada; Axel Brandenburg; Matthias Rempel; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Magnetohydrodynamics MHD ; turbulence; dynamo; Sun: magnetic fields; Sun: rotation; Sun: activity; Sun: dynamo; Astronomy; astronomi;

    Sammanfattning : Sunspots stand out on the visible solar surface. They appear as dark structures evolving and changing over time. They host energetic and violent events, like coronal mass ejections and flares, and concentrate strong magnetic fields. LÄS MER

  3. 12. Domain-Informed Signal Processing with Application to Analysis of Human Brain Functional MRI Data

    Författare :Hamid Behjat; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :;

    Sammanfattning : Standard signal processing techniques are implicitly based on the assumption that the signal lies on a regular, homogeneous domain. In practice, however, many signals lie on an irregular or inhomogeneous domain. An application area where data are naturally defined on an irregular or inhomogeneous domain is human brain neuroimaging. LÄS MER

  4. 13. Here be monsters: Investigating sociotechnical interaction in safety-critical work in the maritime domain

    Författare :Linda de Vries; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pilotage; Functional Resonance Analysis Method FRAM ; e-navigation; safety; Resilience Engineering; Vessel Traffic Services VTS ; Human Factors; sociotechnical systems;

    Sammanfattning : Maritime Pilots and Vessel Traffic Services (VTS) operators work to improve the safety of navigation of seagoing vessels. As in many other safety-critical domains, work is increasingly characterised by the integration and dissemination of information between humans and technology, across disciplines and over multiple geographical locations.

  5. 14. Improving Drug Discovery Decision Making using Machine Learning and Graph Theory in QSAR Modeling

    Författare :Ernst Ahlberg Helgee; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; machine-learning; QSAR; descriptor importance; local and global models; method of manufactured solutions; automated compound optimization; drug design;

    Sammanfattning : During the last decade non-linear machine-learning methods have gained popularity among QSAR modelers. The machine-learning algorithms generate highly accurate models at a cost of increased model complexity where simple interpretations, valid in the entire model domain, are rare. LÄS MER

  7. 15. Breakdown situations in dialogues between humans and socially intelligent agents

    Författare :Maitreyee Tewari; Helena Lindgren; Kai-Florian Richter; Olov Engwall; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Dialogues; Breakdown Situations; Focus Shift; Human-Centric Artificial Intelligence; Engeström’s Activity Triangle; We-Intention; Argumentation-Based Dialogues; Grice’s Cooperative Principle; Communicative Functions; Wizard-of-Oz; User Studies; Thematic Analysis; Sequence Organisation; Computer Science; datalogi;

    Sammanfattning : Dialogues between humans are complex due to the challenges in predicting how they will unfold as people may want to achieve different purposes. For instance, to act together, they co-create a common goal; to learn, they co-create knowledge; to build relationships, they share emotions and beliefs. LÄS MER
