  2. 11. Improving the functionality of synchronous machines using power electronics

    Author : Fredrik Evestedt; Urban Lundin; C. Johan. D. Abrahamsson; Jon Kjellin; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power electronics; Synchronous machines; Excitation systems; Magnetic thrust bearing; Starting synchronous machines; Split rotor; Rotating electronics; Magnetic fields; Measurement systems; Unbalanced magnetic pull; Harmonics; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : With the advent of modern power electronics there is reason to explore what can be achieved when it is applied to a mature technology like synchronous machines. In this text several concepts will be presented on how it is possible to control forces and how to get better performance out of synchronous machines by using power electronics. READ MORE

  4. 12. Preparing Spatial Haptics for Interaction Design

    Author : Jonas Forsslund; Eva-Lotta Sallnäs Pysander; Ylva Fernaeus; Jan Gulliksen; Karl-Johan Lundin-Palmerius; Karon MacLean; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; haptics; interaction design; surgery simulation; haptik; interaktionsdesign; medicinsk simulering; kirurgi; Människa-datorinteraktion; Human-computer Interaction;

    Abstract : Spatial haptics is a fascinating technology with which users can explore and modify3D computer graphics objects with the sense of touch, but its application potentialis often misunderstood. For a large group of application designers it is still unknown,and those who are aware of it often have either too high expectations of what is technicallyachievable or believe it is too complicated to consider at all.

  5. 13. Large data and machine learning in analysis, diagnostics, and clinical decision making: applications in the treatment of burn injury

    Author : Jian Fransén; Fredrik Huss; Johan Lundin; Yvette Andersson; Andrew Lindford; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Burn wound infection; Antibiotic susceptibility; Burn mortality; Machine learning; Burns; Burn assessment; Convolutional neural network; Artificial intelligence; Intensive care; ; Plastikkirurgi; Plastic Surgery; Surgery; Kirurgi; Machine learning; Maskininlärning;

    Abstract : Burn injury is a common trauma globally. Large burns require fluid resuscitation, infection control, and specialized intensive care. The size of the burn and infections caused by resistant microbes are correlated to mortality, and accurate mortality predictions are important. READ MORE

  6. 14. Adaptive immune response in the intestinal mucosa of microscopic colitis patients

    Author : Ashok Kumar Kumawat; Elisabeth Hultgren-Hörnquist; Johan Bohr; Curt Tysk; Allan Sirsjö; Samuel Lundin; Örebro universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microscopic colitis; collagenous colitis; lymphocytic colitis; intraepithelial lymphocytes; lamina propria lymphocytes; T cell receptor excision circle; T helper cells; cytotoxic T lymphocyte and mucosal cytokines; Biomedicin; Biomedicine;

    Abstract : Microscopic colitis (MC) is a chronic diarrhoeal disease of unknown aetiology, comprising collagenous colitis (CC) and lymphocytic colitis (LC). The nature of the adaptive local immune responses in the mucosa of MC patients is however far from elucidated. READ MORE

  7. 15. Teachers’ challenges and school digitalization : Exploring how teachers learn about technology integration to meet local teaching needs

    Author : Tiina Leino Lindell; Stefan Hrastinski; Fredrik Enoksson; Johan Lundin; KTH; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Teknik och lärande; Technology and Learning;

    Abstract : Today’s teachers are constantly faced with challenges. Society is changing, which places new demands on the content of education and teachers’ knowledge. Many countries have introduced digital competence to their curricula to prepare students for the digital society. READ MORE
