    Sammanfattning : Chronic lateral instability of the ankle (CLI), defined as frequent sprains and recurrent giving way, difficulty in walking and running on uneven surface, is often connected with pain and swollen ankles. It occurs in 10 to 20 percent after acute ankle injuries. LÄS MER

  3. 2. The Impact of Fracture Geometry on the Hydromechanical Behaviour of Crystalline Rock

    Författare :Johan Thörn; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Laboratory experiments; Fracture aperture; In situ experiments; Conceptual model; Äspö HRL; Fracture geometry; Stereo photogrammetry; Hydromechanical coupling; Fracture normal stiffness;

    Sammanfattning : Effective construction of tunnels in fractured crystalline rock requires a unified approach for handling rock mechanics and hydrogeological issues. Traditionally, rock mechanics and hydrogeology not only use different nomenclature, they also measure parameters such as e.g. aperture differently. LÄS MER

    Sammanfattning : 3D information extracted by image matching of aerial images, so called image-based point clouds, have been found to provide accurate vegetation height measurements. This has led to an increased interest from the vegetation mapping community, since aerial images are an affordable alternative to airborne laser scanner (ALS) data. LÄS MER
