  1. 21. Nature-inspired passive flow control using various coatings and appendages

    Författare :Ugis Lacis; Shervin Bagheri; Christophe Eloy; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flow control; passive appendage; surface coating; pressure drag; friction drag; Flödeskontroll; passiva bihang; ytbeläggning; tryckmotstånd; friktionsmotstånd;

    Sammanfattning : There is a wide variety of tails, fins, scales, riblets and surface coatings, which are used by motile animals in nature. Since organisms currently living on earth have gone through millions of years of evolution, one can expect that their design is optimal for their tasks, including locomotion. LÄS MER

  3. 22. Adoption of the Innovation System Concept in Sweden

    Författare :Magnus Eklund; Lars Magnusson; Mats Larsson; Dan Bäcklund; Mats Benner; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; conceptual history; Quentin Skinner; innovation system concept; innovation thinking; VINNOVA; OECD; Sweden; research policy; research funding reform; Research 2000; sectoral research; university autonomy; industrial policy; industrial crisis; Economic history; Ekonomisk historia;

    Sammanfattning : In 2001 Sweden founded the government agency of VINNOVA, named after the OECD-endorsed innovation system concept. Criticising the common assumption that countries are passive and uncritical recipients of the approaches promoted by the OECD, this dissertation tries to show that Swedish actors were in fact very active and strategic as they contributed to the national adoption of the concept.

  4. 23. Passive Houses in Sweden. From Design to Evaluation of Four Demonstration Projects

    Författare :Ulla Janson; Avdelningen för Energi och byggnadsdesign; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Planning process; Energy efficiency; Passive house; Buildingconstruction; Residential buildings; Ventilation;

    Sammanfattning : The use of energy is a major global issue both according to climate changes but also in the aspect of national safety tied to the trade with energy sources. Of the total energy use in the member states of the European Union, about 40% is used in residential and commercial buildings. LÄS MER

  5. 24. High performance breath alcohol analysis

    Författare :Jonas Ljungblad; Mikael Ekström; Olof Lindahl; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; elektronik; Electronics;

    Sammanfattning : Alcohol breath testing on a larger scale will save lives. Alcohol intake affects the human body by significantly longer response time to external stimuli. LÄS MER

  7. 25. Multivariate Data Analytics to Identify Driver’s Sleepiness, Cognitive load, and Stress

    Författare :Shaibal Barua; Shahina Begum; Peter Funk; Mobyen Uddin Ahmed; Christer Ahlström; Nirmalie Wiratunga; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Driver monitoring; Driver state; Physiological signals; Machine learning; Contextual information; Computer Science; datavetenskap;

    Sammanfattning : Driving a vehicle in a dynamic traffic environment requires continuous adaptation of a complex manifold of physiological and cognitive activities. Impaired driving due to, for example, sleepiness, inattention, cognitive load or stress, affects one’s ability to adapt, predict and react to upcoming traffic events. LÄS MER
