    Sammanfattning : Recent trends in the shipping industry, e.g., expanded routing in ecologically sensitive areas and emission regulations, have sharpened the perception of efficient propeller designs. Currently, propeller efficiency, estimated fuel consumption and, more often, propeller-radiated noise are parameters that steer the business Zeitgeist. LÄS MER

  4. 8. Interference Mitigation Techniques in FMCW Automotive Radars

    Författare :Muhammad Rameez; Mats Pettersson; Gary Smith-Jonforsen; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Radar has emerged as an important sensor for scenario perception in automated driving and surveillance systems. The exponential increase of radar units in traffic and their operating frequency limitations have given rise to the problem of mutual interference. LÄS MER

    Sammanfattning : The overarching question for this thesis is what is preschool mathematics? This question is examined using different points of views or different perspectives such as the children’s, the preschool teachers and the researchers. The foundation for this thesis is seven articles, two single author articles and five co-authored articles. LÄS MER
