    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Physics Education Research; IR cameras; thermal cameras; thermodynamics; phase transition; heat transfer; Resources framework; Social semiotics; teacher education; chemistry education; visualization; Fysikdidaktik; kemididaktik; värmekamera; lärarutbildning; termodynamik; fasövergång; lärandesekvens; Socialsemiotik; Resursramverket; Physics with specialization in Physics Education; Fysik med inriktning mot fysikens didaktik;

    Sammanfattning : In this Licentiate thesis, framed by the Resources framework and Social semiotics, I explore how students and instructors, investigating thermal phenomena with IR cameras, come to conceptually and epistemologically frame the naturalistic settings they participate in. Additionally, I look at how they productively employ resources , what barriers they encounter while reasoning about the thermal phenomena and how the semiotic resources of the IR camera relate to the framing and resources employed in their investigations.

  3. 2. Inertial Navigation and Mapping for Autonomous Vehicles

    Författare :Martin Skoglund; Fredrik Gustafsson; Thomas Schön; Tim Bailey; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SLAM; Inertial Navigation; Filtering; Smoothing; Cameras; Optimisation; Autonomous;

    Sammanfattning : Navigation and mapping in unknown environments is an important building block for increased autonomy of unmanned vehicles, since external positioning systems can be susceptible to interference or simply being inaccessible. Navigation and mapping require signal processing of vehicle sensor data to estimate motion relative to the surrounding environment and to simultaneously estimate various properties of the surrounding environment.

  4. 3. Tracking the Wanders of Nature

    Författare :Clas Veibäck; Gustaf Hendeby; Fredrik Gustafsson; Hans Driessen; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Target Tracking; Sensor Fusion; Motion Models; Animals; Cameras; Radar;

    Sammanfattning : Target tracking is a mature topic with over half a century of mainly military and aviation research. The field has lately expanded into a range of civilian applications due to the development of cheap sensors and improved computational power. LÄS MER

  5. 4. Tracking of Animals Using Airborne Cameras

    Författare :Clas Veibäck; Gustaf Hendeby; Fredrik Gustafsson; Kalle Åström; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The various elements of a modern target tracking framework are covered. Background theory on pre-processing, modelling and estimation is presented as well as some novel ideas on the topic by the author. In addition, a few applications are posed as target tracking problems for which solutions are gradually constructed as relevant theory is covered. LÄS MER

  7. 5. Continuous Models for Cameras and Inertial Sensors

    Författare :Hannes Ovrén; Per-Erik Forssen; Klas Nordberg; David Törnqvist; Frank Dellaert; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Using images to reconstruct the world in three dimensions is a classical computer vision task. Some examples of applications where this is useful are autonomous mapping and navigation, urban planning, and special effects in movies. LÄS MER
