  1. 16. Närhet : Samspel och delaktighet i förskolan för barn med utvecklingsstörning

    Författare :Agneta Luttropp; Mats Granlund; Lise Roll-Pettersson; Ulf Janson; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; children with intellectual disability; children with typical development; preschool; interaction; participation; specialpedagogik; Special Education;

    Sammanfattning : The main purpose was to study if children with intellectual disability interact or participate differently with preschool staff and peers compared to their non-disabled peers and how preschool teachers experience interaction and participation for children with intellectual disability and children with typical development. The results from study I show that there are more similarities than differences between the groups. LÄS MER

  3. 17. Power to gas : Bridging renewable electricity to the transport sector

    Författare :Farzad Mohseni; Per Alvfors; Mats Westermark; Lars Pettersson; Maria Grahn; Björn Frostell; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transport; renewable electricity; synthetic fuels; energy; power to gas;

    Sammanfattning : Globally, transport accounts for a significant part of the total energy utilization and is heavily dominated by fossil fuels. The main challenge is how the greenhouse gas emissions in road transport can be addressed. Moreover, the use of fossil fuels in road transport makes most countries or regions dependent on those with oil and/or gas assets. LÄS MER

  4. 18. 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

  5. 19. Signal Processing Approaches for Interference Mitigation in Automotive Radar Systems

    Författare :Muhammad Rameez; Mats Pettersson; Mattias Dahl; Saleh Javadi; Igal Bilik; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; automotive radar; autoregressive modeling; digital beamforming; interference mitigation; machine learning; mutual interference; pulse compression; radar signal processing; signal reconstruction; Systemteknik; Systems Engineering;

    Sammanfattning : Modern vehicles have several autonomous and semi-autonomous features, such as adaptive cruise control, lane keeping, adaptive headlights, and automatic emergency braking, ensuring a safe and comfortable driving experience. The vehicles typically rely on different sensors to "see" their surroundings and make decisions accordingly. LÄS MER

  7. 20. GNSS Radio Occultation Inversion Methods and Reflection Observations in the Lower Troposphere

    Författare :Thomas Sievert; Mats Pettersson; Viet Thuy Vu; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GNSS Radio Occultation GNSS-RO ;

    Sammanfattning : GNSS Radio Occultation (GNSS-RO) is an opportunistic Earth sensing technique where GNSS signals passing through the atmosphere are received in low Earth orbit and processed to extract meteorological parameters. As signals are received along an orbit, the measured Doppler shift is transformed to a bending angle profile (commonly referred to as bending angle retrieval), which, in turn, is inverted to a refractivity profile.
