  1. 1. Movement strategies and dynamic knee control after anterior cruciate ligament injury : a three-dimensional biomechanical analysis

    Författare :Jonas L. Markström; Charlotte K. Häger; Eva Tengman; Helena Grip; Lina Schelin; Jim Richards; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anterior cruciate ligament; biomechanics; kinematics; kinetics; finite helical axis; injury prevention; sports; reliability; agreement; one-leg hops; functional data analysis; physiotherapy; fysioterapi;

    Sammanfattning : Background: Rupture of the anterior cruciate ligament (ACL) is common and mainly occurs in non-contact situations in sports, often due to momentarily poor movement control. Assessment of movement quality during sport-like tasks iscrucial to understand how to decrease the high risk of reinjury for ACL-injured persons, but also how to prevent primary injury. LÄS MER

  3. 2. Three Dimensional Hydro-Morphological Modeling of Tigris River

    Författare :Ammar Ali; Robert William Duck; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Sammanfattning : The River Tigris is a major river in Iraq. It divides Baghdad, the capital of Iraq, in two parts. The reach of the river within Baghdad is about 60 km long. The climate change within the region and the construction of hydraulic structures upstream of Baghdad has reduced the water discharge of the river by 44%. LÄS MER

  4. 3. A three dimensional scaffold for single staged tissue engineering

    Författare :Said Zeiai; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Study I. Aims: Evaluate a collagen-PCL scaffold with minced bladder mucosa in vitro. M&M: Minced tissue was cultured on top of the scaffold. Scaffold properties were evaluated. LÄS MER

  5. 4. Automatic Dense Reconstruction from Uncalibrated Video Sequences

    Författare :David Nister; KTH; []
    Nyckelord :Structure from Motion; Calibration; Match Moving; Reconstruction; Video; Computer Vision; Auto-calibration; Augmented Reality; Virtual Reality; Image-based Rendering; Visualisation; Camera Calibration; Motion Estimation;

    Sammanfattning : This thesis describes a system that completely automaticallybuilds a three-dimensional model of a scene given a sequence ofimages of the scene. The system also estimates the internalparameters of the camera and the poses from where the originalimages were taken. LÄS MER
