  1. 1. Hydrological Modelling, Topographical Influence and Yield Mapping in Precision Agriculture

    Detta är en avhandling från Andreas Persson, GIS Centre, Lund University, Sölvegatan 12, 223 62, Lund, Sweden

    Författare :Andreas Persson; [2004]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Spatially distributed hydrological modelling; Precision Agriculture; Yield mapping; Topographical wetness index; Drainage area; Lantbrukshydrologi; marklära; agricultural hydrology; Soil Science;

    Sammanfattning : The use of topographical data in hydrological and agricultural applications has increased with GPS data availability and the concept of precision agriculture. This thesis investigates the relationships between topography and in one case simulated soil moisture and in the other case yield. LÄS MER

  4. 4. Leisure in adolescence : youths' activity choices and why they are linked to problems for some and not others

    Detta är en avhandling från Örebro : Örebro universitetsbibliotek

    Sammanfattning : Adolescents spend a great amount of time engaged in different leisure activities. Some of the activity choices they make can put them at risk for negative socialization. In particular, peer-oriented, unstructured activities such as hanging out on the streets or at neighborhood recreation centers have been linked to problem development. LÄS MER

  5. 5. Studies in Semantic Modeling of Real-World Objects using Perceptual Anchoring

    Detta är en avhandling från Örebro : Örebro University

    Författare :Andreas Persson; Amy Loutfi; Alessandro Saffiotti; Severin Lemaignan; [2019]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Perceptual Anchoring; Semantic World Modeling; Sensor-Driven Acquisition of Data; Object Recognition; Object Classification; Symbol Grounding; Probabilistic Object Tracking;

    Sammanfattning : Autonomous agents, situated in real-world scenarios, need to maintain consonance between the perceived world (through sensory capabilities) and their internal representation of the world in the form of symbolic knowledge. An approach for modeling such representations of objects is through the concept of perceptual anchoring, which, by definition, handles the problem of creating and maintaining, in time and space, the correspondence between symbols and sensor data that refer to the same physical object in the external world.
