    Sammanfattning : This thesis investigates early modern ways of looking at the world through an analysis of what the continents meant in three settings of knowledge making in seventeenth-century Sweden. Combining text, maps and images, the thesis analyses the meaning of the continents in, first, early modern scholarly ‘geography’, second, accounts of journeys to the Ottoman Empire and, third, accounts of journeys to the colony New Sweden.

  3. 22. Optical shape measurements using temporal phase unwrapping

    Författare :Lars Kinell; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimental Mechanics; Experimentell mekanik;

    Sammanfattning : This doctoral thesis is devoted to optical shape measurements using an analysis scheme called temporal phase unwrapping. This scheme makes it possible to determine the absolute distance from a detector (usually a camera’s CCD-detector) to an object. Two different optical methods are considered for this 3-D sensing.

  4. 23. Sensor Fusion for Automotive Applications

    Författare :Christian Lundquist; Fredrik Gustafsson; Thomas B. Schön; Uwe Hanebeck; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kalman filter; PHD filter; extended targets; tracking; sensor fusion; road model; single track model; bicycle model;

    Sammanfattning : Mapping stationary objects and tracking moving targets are essential for many autonomous functions in vehicles. In order to compute the map and track estimates, sensor measurements from radar, laser and camera are used together with the standard proprioceptive sensors present in a car. LÄS MER

  5. 24. Shape measurements using temporal phase unwrapping

    Författare :Lars Kinell; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimental Mechanics; Experimentell mekanik;

    Sammanfattning : This licentiate thesis is devoted to shape measurements using two different optical methods. The first one is a classical triangulation method, which uses projected fringes. The second one is a new interferometric method, which uses wavelength scanning. Both are whole field measuring methods. LÄS MER

  7. 25. Delocalization in nonperiodic systems

    Författare :Lars Kroon; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The localization properties of non-interacting linear excitations in one-dimensional aperiodically ordered structures are investigated from a theoretical point of view. The models used have various relevance for real systems, like quasicrystals, photonic crystals, and deterministic aperiodic superlattices. LÄS MER
